WDR4 as a potential indicator of clinical prognosis and immunotherapy in hepatocellular carcinoma.

e16275 Background: Immunotherapy has garnered increasing attention in hepatocellular carcinoma (HCC) treatment. However, there remains a pressing need for effective immunological predictive biomarkers. In our previous study, utilizing data extracted from The Cancer Genome Atlas (TCGA) database, we identified a positive correlation between WDR4 expression levels in hepatocellular carcinoma and various clinical parameters, encompassing Stage, T-stage, pathological grade, AFP level, and vascular invasion. Additionally, higher WDR4 expression was linked to poorer prognosis. Leveraging The TIMER and GEPIA databases, we further elucidated a significant association between WDR4 expression levels and the extent of immune cell infiltration, particularly macrophages, B lymphocytes, and myeloid suppressor cells, in hepatocellular carcinoma. These findings propose the potential utility of WDR4 as a biomarker for immune infiltration in hepatocellular carcinoma. As noted in the trial NCT03867084, which hypothesized that adjuvant pembrolizumab might surpass placebo efficacy, there still exists a gap in identifying the specific population benefiting from adjuvant immunotherapy. Methods: Clinical and pathological data from patients who underwent single-agent immunotherapy for HCC were additionally collected from Hunan Provincial People's Hospital between January 1, 2019, and January 31, 2024. These patients participated in the clinical trial (NCT03867084) with informed consent. The relationship between WDR4 expression levels, clinical pathological data, and patient prognosis was assessed using the Kruskal-Wallis test and Kaplan-Meier survival curve analysis. Results: WDR4 displayed significant upregulation in HCC tissues compared to para-carcinoma tissues (P < 0.001) and exhibited robust diagnostic potential. WDR4 expression showed significant associations with various immune cells, including macrophages (r = 0.278, P < 0.001). Kaplan-Meier survival analysis indicated that patients with high WDR4 expression had shorter postoperative progression-free survival in the context of immunotherapy. Data from 37 patients who underwent postoperative single-agent immunotherapy for hepatocellular carcinoma (NCT03867084) revealed a significant correlation between WDR4 expression levels and Disease-Free Survival (DFS), with notable statistical significance (Log-rank P < 0.001). Conclusions: WDR4 demonstrates elevated expression levels within HCC tissues and is associated with immune infiltration, establishing it as a prognostic biomarker in HCC. Furthermore, the positive correlation observed between WDR4 and CD68 as well as PD-L1 underscores its potential as a guiding factor in immunotherapeutic approaches for HCC.

Efficacy and safety of donafenib combined with anti-PD-1 antibodies for initially unresectable hepatocellular carcinoma (HCC): A retrospective real-world study.

e16131 Background: Given its clear efficacy and high safety demonstrated in the phase 3 ZGDH3 study, donafenib has been recommended by the Chinese guidelines for the first-line treatment of unresectable hepatocellular carcinoma (uHCC). Recently, combination therapies have shown favorable results. However, the clinical experience of donafenib combined with anti-PD-1 therapy for uHCC has not yet been investigated. Thus, we aimed to investigate the efficacy and safety of donafenib combined with anti-PD-1 antibody in the treatment of uHCC. Methods: A single-center, retrospective study was performed based on the medical records of consecutive patients diagnosed with HCC who were not suitable for curative surgery at Hunan Provincial People's Hospital from July 2021 to September 2023. Patient with ≥18 years, no prior systemic therapy, having at least one measurable lesion (per mRECIST) were enrolled. Patients were treated with donafenib and anti-PD-1 antibodies until disease progression or unacceptable toxicity, local treatment such as TACE, HAIC or ablation were allowed. The primary endpoint was progression-free survival (PFS) by mRecist criteria, and secondary endpoints included overall survival (OS), objective response rate (ORR) and disease control rate (DCR) by mRecist criteria, and safety. The last follow-up time was December 15, 2023. Results: In total, 48 patients were enrolled: 87.5% males, median age 59.5 years (range, 32.0-78.0), 95.8% ECOG of 0, 68.8% HBV positive, 14.6% BCLC stage B, 75.0% BCLC stage C, 47.9% baseline AFP≥400 ng/mL, 70.8% with macrovascular invasion. Among them, 9 patients (18.8%) received donafenib combined with anti-PD-1 antibody as first-line treatment, 37 (77.1%) with concurrent TACE(n = 25) or HAIC(n = 6) or both as treatment(n = 6), 2 (4.2%) received ablation treatment. At the time of data cut-off, the median follow-up time was 10.0 months (95% CI, 6.37-12.2). Considering efficacy, 9 pts (18.7%) achieved complete response, 20 (41.7%) achieved partial response, 17 (35.4%) had stable disease, and 2(4.2%) had progressive disease. The ORR and DCR were 60.4% and 95.8% by mRecist, respectively. Median progression-free survival was 15.8 months (95% CI, 8.9-NA). Median overall survival was not reached, 12-month OS rate were 90.7% (95% CI:73.7%-96.9%). In terms of safety, 44 pts (91.7%) had TRAEs. The incidence of ≥grade 3 TRAEs was 33.3% (16/48). Common TRAEs included elevated AST(45.8%), hand-foot syndrome (39.6%), decreased platelet count(35.4%),elevated ALT(31.2%), rash (25.0%) and decreased white blood cell count (14.6%). Grade 3/4 TRAEs included elevated AST(10.4%), elevated ALT(8.3%), rash(8.3%) and hand-foot syndrome (8.3%). No grade 5 TRAEs were observed. Conclusions: Donafenib combined with anti-PD-1 antibodies shows promising efficacy and manageable toxicity in patients with initially uHCC.

Prediction of footplate position after implantable collamer lens implantation based on iris and ciliary body morphologies.

To investigate the factors affecting footplate position and its influence on vault characteristics after implantable collamer lens (ICL) implantation. Hunan Provincial People's Hospital, Changsha, China. Retrospective case series. This study included 124 patients (124 eyes). Ultrasound biomicroscopy (UBM) was performed to assess the iris and ciliary body morphologies and observe the footplate position. Using multiple linear regression, the relationship between various ocular and ICL parameters and the vault as well as the factors affecting the footplate distance (FD) were analyzed. Based on the FD, 3 groups were formed: group 1 (<500 μm), group 2 (500 to 1000 μm), and group 3 (>1000 μm). The distribution of the vault range postoperatively was observed for the 3 groups. Ciliary sulcus angle and FD significantly affected the vault (adjusted R2 = 0.190, F = 6.763, P < .001), with FD being the most important factor influencing the vault (β = -0.383, P < .001). Postoperative UBM revealed that the footplate was located at different positions in the posterior chamber, with the majority (52%) being located on the ciliary body. The mean size of the 4 footplate orientations was 0.88 ± 0.24 mm. Multiple linear regression analysis revealed that ciliary body thickness (CBT), iris curvature (IC), and ICL iris contact length (IRCL) significantly influenced the FD (adjusted R2 = 0.373, F = 11.432, P < .001). The vault range differed significantly among the 3 groups (X 2 = 32.33, P < .001). Different postoperative ICL footplate positions significantly affect the vault. CBT, IC, and IRCL can alter the position of the footplate from the expected position. This study provides reference for ICL size selection and vault prediction.

To summarize the clinical data of 7 children with activated phosphoinositide 3-kinase delta syndrome (APDS) and enhance understanding of the disease. A retrospective analysis was conducted on clinical data of 7 APDS children admitted to Hunan Provincial People's Hospital from January 2019 to August 2023. Among the 7 children (4 males, 3 females), the median age of onset was 30 months, and the median age at diagnosis was 101 months. Recurrent respiratory tract infections, hepatosplenomegaly, and multiple lymphadenopathy were observed in all 7 cases. Sepsis was observed in 5 cases, otitis media and multiple caries were observed in 3 cases, and diarrhea and joint pain were observed in 2 cases. Lymphoma and systemic lupus erythematosus were observed in 1 case each. Fiberoptic bronchoscopy was performed in 4 cases, revealing scattered nodular protrusions in the bronchial lumen. The most common respiratory pathogen was Streptococcus pneumoniae (4 cases). Six patients had a p.E1021K missense mutation, and one had a p.434-475del splice site mutation. p.E1021K is the most common mutation site in APDS children. Children who present with one or more of the following symptoms: recurrent respiratory tract infections, hepatosplenomegaly, multiple lymphadenopathy, otitis media, and caries, and exhibit scattered nodular protrusions on fiberoptic bronchoscopy, should be vigilant for APDS.

Efficacy analysis of 7 cases of mixed neuroendocrine-nonneuroendocrine neoplasm of the duodenal papilla

The clinical data of 7 patients diagnosed with mixed neuroendocrine-nonneuroendocrine neoplasm were analyzed in the Department of Hepatobiliary Surgery of Hunan Provincial People's Hospital from January 2016 to December 2022. Among the 7 patients, 5 were male and 2 were female, with an average age of 59.3 years. Its clinical characteristics are similar to malignant ampulla tumors, and it is difficult to differentiate them. The preoperative puncture biopsy positivity rate is low, making it difficult to diagnose preoperatively, and the prognosis is worse.Comprehensive treatment including surgery, chemotherapy, and radiotherapy can be the preferred treatment option for this disease.

HE4 Serum Levels are Associated with Poor Prognosis in Patients with Acute Heart Failure Combined with Chronic Kidney Disease.

The levels of human epididymis protein 4 (HE4) is associated not only with the prognosis of patients with acute heart failure (AHF), but also with chronic kidney disease (CKD). Our study aims to understand the prediction value of HE4 on prognosis in patients with AHF combined with CKD. This study prospectively enrolled patients diagnosed with AHF combined with CKD at the Department of Cardiology of Hunan Provincial People's Hospital from March 2019 to December 2022. Serum levels of HE4 were measured using a chemiluminescence microparticle immunoassay. The endpoint events included heart failure readmission and cardiovascular death. A total of 130 patients with AHF combined with CKD were included in the stud. The median age is 73 years (interquartile range: 65-79 years). Among the patients, 94 experienced the endpoint events. The multivariable Cox analysis reveals that LnHE4 (HR=2.280, 95% CI 1.300-3.998, P = 0.004) and age (HR=1.024, 95% CI 1.003-1.045, P = 0.025) are independent predictors of the endpoint events. The Kaplan-Meier survival curve demonstrates that patients with HE4 levels>276.15 pmol/L has a significantly higher incidence of endpoint events compared to those with HE4 levels≤276.15 pmol/L (Log rank test: χ2=19.689, P < 0.001). After adjusting for age and gender, the HR is 2.520 (95% CI: 1.626-3.906, P < 0.001). HE4 is an independent predictor of heart failure readmission and cardiovascular death in patients with AHF combined with CKD.

Neutrophil CD64 index as a new early predictive biomarker for infected pancreatic necrosis in acute pancreatitis

ObjectiveInfectious pancreatic necrosis (IPN) is a serious complication of acute pancreatitis, and early recognition and timely intervention are the keys to improving clinical outcomes. The purpose of this study was to investigate the predictive capacity of the neutrophil CD64 index (nCD64 index) on IPN in patients with acute pancreatitisMethodsThis study comprises two independent cohorts: the training cohort consisted of 202 patients from Hunan Provincial People's Hospital, and the validation cohort consisted of 100 patients from Changsha Central Hospital. Peripheral blood samples were collected on the day of admission and on the 3rd, 5th, 7th, and 10th days of hospitalization, and the nCD64 index was detected by flow cytometry. Additionally, relevant clinical characteristics and laboratory biomarkers were collected and analyzed.ResultsWe observed that nCD64 index on admission was significantly higher in the IPN group than Non-IPN group (p < 0.001). In the training cohort, a higher occurrence rate of IPN was observed in the high nCD64 index group compared to the moderate and low nCD64 index group (p < 0.001). Further analysis showed that nCD64 index was significant positive correlated with the incidence rate of IPN (p < 0.001, correlation coefficient = 0.972). Furthermore, logistic regression analysis showed that high expression of the nCD64 index on admission was a risk factor for the occurrence of IPN (OR = 2.971, p = 0.038). We further found that the nCD64 index of IPN patients was significantly higher than the Non-IPN patients on the days 1, 3, and 5 after admission, and the nCD64 index of IPN patients before and after the onset (p < 0.05). At the same time, this study revealed that the nCD64 index on admission showed good predictive efficacy for IPN (AUC = 0.859, sensitivity = 80.8%, specificity = 87.5%), which was comparable to APACHE II score. And this finding was further validated in an independent cohort of 100 participants (AUC = 0.919, Sensitivity = 100.0%, Specificity = 76.6%).ConclusionThis study demonstrated the clinical value of nCD64 index in patients with IPN patients for the first time through two independent cohort studies. The nCD64 index can be used as an early prediction and risk assessment tool for the occurrence of IPN, contributing to the improvement of patient outcomes and efficiency of medical resource allocation.

Qualitative research on the cognition of breastfeeding knowledge in primiparas during pregnancy.

In view of the lack of attention and predictability in postpartum breastfeeding in primiparas, health education on breastfeeding during pregnancy should be carried out to publicize the benefits of breastfeeding. To investigate how well the primiparas during pregnancy are known of breastfeeding knowledge, and to provide a basis for developing health education measures for them. With the adoption of the objective sampling method and the principle of saturation, 10 primiparas in the obstetrics outpatient department of the Hunan Provincial People's Hospital were selected as the study participants. Semi-structured in-depth interviews combined with the observation method were used for data collection. The interview data were analyzed and the theme was refined by Colaizzi's seven-step method. The results of the four themes of the cognition of breastfeeding knowledge among primiparas were as follows: Lack of knowledge and curiosity about breastfeeding in some women, lack of access to correct breastfeeding knowledge, insufficient support from family members for postpartum breastfeeding, and lack of approach to solve problems during breastfeeding among primiparas. Due to the current problems of the cognition of breastfeeding knowledge in primiparas, it was imperative to build a health education model suitable for primiparas to improve this knowledge.

Comparison of asymmetric Z-plasty and Stallard Z-plasty in correction of epicanthus.

To investigate the clinical effect of asymmetric Z-plasty with central axis inward displacement and stallard Z-plasty in the correction of epicanthus. We retrospectively analyzed 193 patients who underwent epicanthal plasty in the Department of Plastic and Laser Cosmetology of Hunan Provincial People's Hospital from 2009 to 2019. The patients were divided into two groups according to different surgical methods: group A (n = 125) received the asymmetric Z-plasty with central axis inward displacement method and group B (n = 68) received the stallard Z-plasty method. The incidence of early postoperative complications, epicanthus retraction and scar concealment from 6 months after the operation were analyzed and evaluated. After 7 days postoperation, both group A and B of patients had grade A wound healing without any infection or poor wound healing. As for the retraction of the epicanthus, 97.6% of group A patients had no retraction and 2.7% had mild retraction, while 92.6% of group B patients had no retraction and 7.4% had mild retraction. The rank-sum test showed no statistically significant difference (p > 0.05) between the two groups. Regarding scar concealment, 35.2% of group A patients had partially hidden scars and 64.8% had completely hidden scars, while 72.1% of group B patients had no hidden scars and 27.9% had partially hidden scars, with a statistically significant difference (p < 0.05). Compared with stallard Z-plasty, asymmetric Z-plasty with central axis inward displacement has the advantages of concealed incision, easier scar concealment, less scar hyperplasia and stable effect, which results in higher postoperative satisfaction.

Salvage Treatment of Nivolumab and Lenvatinib in Patients with Recurrent Hepatocellular Carcinoma

Background: The clinical efficacy of Lenvatinib (a multi‐kinase inhibitor) and Nivolumab (an immune checkpoint inhibitor) have been shown in the management of hepatocellular carcinoma (HCC). However, real-life experience data of HCC patients receiving the Nivolumab and Lenvatinib combination are scarce, especially those who experienced the first-line or even multi-line treatment. Methods: Recurrent HCC patients (n = 28) treated with Nivolumab plus Lenvatinib as salvage therapy in Hunan Provincial People's Hospital from December 2016 to March 31, 2020, were analyzed. All patients were treated with Nivolumab (3 mg/kg), and Lenvatinib (8 mg/day), and administered every three weeks. Demographics, clinical statistics, and start and end dates of combination therapy were collected and recorded. In addition, progression-free survival (PFS) and OS were calculated from the start of Nivolumab plus Lenvatinib. Treatment outcomes were scored based on the Common Toxicity Criteria for Adverse Events (CTCAE), version 4.0. SPSS17.0 software and GraphPad Prism were used for statistical analyses. Results: All the patients had portal vein tumor thrombus (PVTT) who were in Child-Pugh grade A and Barcelona Clinic Liver Cancer (BCLC) stage C. 11 patients (39.3%) were treated with sorafenib only, and 17 patients (60.7%) were treated with at least two lines of multi-target treatment. The disease control rate (CR+PR+SD) was 23/28 (82.1%), with the median overall survival (OS) and median progression-free survival (PFS) of 8.7 months and 5.7 months, respectively. Hyperbilirubinemia was the most common adverse event encountered with these combinations. However, no grade 3 or 4 toxicity was found in all HCC patients. Conclusions: The combination salvage therapy of Nivolumab and Lenvatinib was found effective in HCC patients, and most importantly, the side effects were controllable, and no grade 3 - 4 side effects were observed.

Left atrial function index predicts poor outcomes in acute myocardial infarction patients treated with percutaneous coronary intervention.

The left atrial function index (LAFI) is an index that combines the left atrial emptying fraction, adjusted left atrial volume and stroke volume. The prognostic value of LAFI in acute myocardial infarction (AMI) patients treated with percutaneous coronary intervention (PCI) is unknown. This study aims to determine whether LAFI predicts prognosis in AMI patients treated with PCI. Patients with newly diagnosed AMI who were treated with PCI at Hunan Provincial People's Hospital from March 2020 to October 2021 were prospectively enrolled. All patients underwent transthoracic echocardiography (TTE) at baseline and follow-up. The endpoint events included rehospitalization due to unstable angina, nonfatal myocardial infarction, rehospitalization due to heart failure and cardiovascular death. A total of 368 patients with AMI (92 women; mean age, 61.45 ± 11.91 years) were studied with a median follow-up of 14 ± 6.58 months. Sixty-nine patients had endpoint events. Patients who presented with events had a significantly lower LAFI than patients without events (34.25 ± 12.86 vs. 48.38 ± 19.42, P < 0.0001). Multivariate Cox analysis demonstrated that LAFI (HR = 0.97 [95% CI: 0.95; 0.99]; P = 0.012) and the Killip classification (HR = 1.51 [95% CI: 1.03; 2.22]; P = 0.034) were independently predictive of endpoint events. Kaplan-Meier survival curves showed that patients with LAFI ≤ 40.17 cm/ml/m2 had higher events than patients with LAFI > 40.17 cm/ml/m2 (HR = 8.53 [95% CI: 4.74; 15.35]; P < 0.0001). LAFI is a strong and independent predictor of adverse events and can be used for risk stratification in patients with AMI treated with PCI.

Comparisons of the Fusion Point of Orbital Septum and Levator Aponeurosis in Patients with and Without Mild Ptosis.

By comparing the position of the fusion point between the oriental orbital septum and the levator aponeurosis of the upper eyelid in Asian without and with mild ptosis, this study explores the relationship between the fusion point and mild ptosis, providing scientific basis for better utilizing the orbital septum to correct mild ptosis. In this study, the outpatients who underwent double eyelid blepharoplasty with incision method in the plastic laser cosmetology department of Hunan Provincial People's Hospital from October 2018 to April 2019 were divided into the normal group and the mild ptosis group. The position of the fusion part of the orbital septum and the aponeurosis of the levator palpebrae superioris was observed in the two groups. There are three types of this position: the height of the fusion part is greater than the width of the tarsal plate, the height of the fusion part is equal to the width of the tarsal plate, and the height of the fusion part is less than the width of the tarsal plate. After the fusion part was exposed during the operation, the width of tarsal plate and the height of fusion part were measured with a scale. The difference of the location of fusion part between the two groups was analyzed. The tarsal plate width was 11.061 ± 0.635mm in the normal group and 11.062 ± 0.675mm in the mild ptosis group. There was no significant difference in tarsal plate width between normal group and mild ptosis group (t = 0.645, p = 0.16). The height of the fusion part was 11.032 ± 0.646mm in the normal group and 11.645 ± 0.429mm in the mild ptosis group. The fusion position of mild ptosis group was higher than that of normal group (t = 3.769, P < 0.05). There was significant difference in the distribution of fusion site between the two groups (x2 =38.00, P < 0.0001). The height of aponeurosis fusion of orbital septum and levator palpebrae superioris in mild ptosis group was higher than that in normal group, which may be the cause of mild ptosis. It is suggested that the appropriate treatment of orbital septum in clinical operation may be effective in the treatment of mild blepharoptosis.

SK-Unet++: An improved Unet++ network with adaptive receptive fields for automatic segmentation of ultrasound thyroid nodule images.

The quality of segmentation of thyroid nodules in ultrasound images is a crucial factor in preventing the cancerization of thyroid nodules. However, the existing standards for the ultrasound imaging of cancerous nodules have limitations, and changes of the echo pattern of thyroid nodules pose challenges in accurately segmenting nodules, which can affect the diagnostic results of medical professionals. The aim of this study is to address the challenges related to segmentation accuracy due to noise, low contrast, morphological scale variations, and blurred edges of thyroid nodules in ultrasound images and improve the accuracy of ultrasound-based thyroid nodule segmentation, thereby aiding the clinical diagnosis of thyroid nodules. In this study, the dataset of thyroid ultrasound images was obtained from Hunan Provincial People's Hospital, consisting of a total of 3572 samples used for the training, validation, and testing of this model at a ratio of 8:1:1. A novel SK-Unet++ network was used to enhance the segmentation accuracy of thyroid nodules. SK-Unet++ is a novel deep learning architecture that adds the adaptive receptive fields based on the selective kernel (SK) attention mechanisms into the Unet++ network. The convolution blocks of the original UNet++ encoder part were replaced with finer SK convolution blocks in SK-Unet++. First, multiple skip connections were incorporated so that SK-Unet++ can make information from previous layers of the neural network to bypass certain layers and directly propagate to subsequent layers. The feature maps of the corresponding locations were fused on the channel, resulting in enhanced segmentation accuracy. Second, we added the adaptive receptive fields. The adaptive receptive fields were used to capture multiscale spatial features better by dynamically adjusting its receptive field. The assessment metrics contained dice similarity coefficient (Dsc), accuracy (Acc), precision (Pre), recall (Re), and Hausdorff distance, and all comparison experiments used the paired t-tests to assess whether statistically significant performance differences existed (p<0.05). And to address the multi-comparison problem, we performed the false discovery rate (FDR) correction after the test. The segmentation model had an Acc of 80.6%, Dsc of 84.7%, Pre of 77.5%, Re of 71.7%, and an average Hausdorff distance of 15.80mm. Ablation experimental results demonstrated that each module in the network could contribute to the improved performance (p<0.05) and determined the best combination of parameters. A comparison with other state-of-the-art methods showed that SK-Unet++ significantly outperformed them in terms of segmentation performance (p<0.05), with a more accurate segmentation contour. Additionally, the adaptive weight changes of the SK module were monitored during the training process, and the resulting change curves demonstrated their convergence. Our proposed method demonstrates favorable performance in the segmentation of ultrasound images of thyroid nodules. Results confirmed that SK-Unet++ is a feasible and effective method for the automatic segmentation of thyroid nodules in ultrasound images. The high accuracy achieved by our method can facilitate efficient screening of patients with thyroid nodules, ultimately reducing the workload of clinicians and radiologists.

Ultrasound-based histological differences of pretarsal fat fascia before and after double eyelid blepharoplasty with the orbital septum method.

To observe the changes of pretarsal fat fascia histological structure after double eyelid blepharoplasty with the orbital septum method. From December 2019 to February 2022, the patients with congenital single eyelid who underwent double eyelid blepharoplasty with the orbital septum method at the Plastic and cosmetic surgery department of Hunan provincial people's Hospital and the same number of congenital double eyelid volunteers. Then divided into three groups: preoperative eyelid ultrasound images in Group A, postoperative eyelid ultrasound images in Group B, and congenital double eyelid volunteers in Group C. To study the histological differences of pretarsal fat fascia before and after double eyelid blepharoplasty with the orbital septum method and congenital double eyelid by ultrasound. Ninety-eight patients who underwent double eyelid blepharoplasty with the orbital septum method met the inclusion criteria. All 98 patients aged 22.88 ± 3.00 years, including 7 males and 91 females, followed up for 6-12 months. Included 98 volunteers with congenital double eyelid, aged 23.58 ± 2.59 years, including 49 males and 49 females. Ultrasound showed that the pretarsal fat fascia was divided into two layers. The dense layer adhered closely to the surface of the tarsus with no statistically significant differences. There was a statistically significant difference in the thickness of the pretarsal loose fat fascia layer between Group A and B. The points a b c in Group A were significantly thicker than those in Group B and C, and there was no significant difference between Group B and C. Postoperative evaluation: 83 cases were satisfied, 11 cases were basically satisfied and 4 cases were unsatisfied. After double eyelid blepharoplasty using orbital septum, the histological structure of pretarsal fat fascia is similar to that of congenital double eyelid, suggesting that double eyelid blepharoplasty with the orbital septum method can change the structure of pretarsal fat fascia and make it similar to congenital double eyelid, which is one of the anatomical bases for its good clinical effect.

Radio frequency identification technology reduce intravenous thrombolysis time in acute ischemic stroke.

To inspect whether time management with radio frequency identification technology (RFID) reduces symptom onset-to-intravenous thrombolysis time (OTT) in acute ischemic stroke (AIS). In the retrospective study, patients with AIS, transferred by Emergency Medical Services (EMS) to Hunan Provincial People's Hospital between September 2019 to June 2022, divided into three groups, as traditional group, in-hospital RFID group and whole process RFID group. Baseline characteristics and time metrics were compared. After the whole emergency process applied with RFID time management, Door to intravenous thrombolysis time (DNT) was reduced from 125.00±43.16 min to 32.59±25.45 min (F = 121.857, p<0.001), and OTT was reduced from 235.53±57.27 min to 144.31±47.96 min (F = 10.377, p<0.001). Time management with RFID is effective in reducing OTT in AIS patients with thrombolysis treatment.

Development and Validation of a Prediction Model of the Risk of Pneumonia in Patients with SARS-CoV-2 Infection.

To establish a prediction model of pneumonia risk in SARS-CoV-2-infected patients to reduce unnecessary chest CT scans. The model was constructed based on a retrospective cohort study. We selected SARS-CoV-2 test-positive patients and collected their clinical data and chest CT images from the outpatient and emergency departments of Hunan Provincial People's Hospital, China. Univariate and multivariate logistic regression and least absolute shrinkage and selection operator (LASSO) regression were utilized to identify predictors of pneumonia risk for patients infected with SARS-CoV-2. These predictors were then incorporated into a nomogram to establish the model. To ensure its performance, the model was evaluated from the aspects of discrimination, calibration, and clinical validity. In addition, a smoothed curve was fitted using a generalized additive model (GAM) to explore the association between the pneumonia grade and the model's predicted probability of pneumonia. We selected 299 SARS-CoV-2 test-positive patients, of whom 205 cases were in the training cohort and 94 cases were in the validation cohort. Age, CRP natural log-transformed value (InCRP), and monocyte percentage (%Mon) were found to be valid predictors of pneumonia risk. This predictive model achieved good discrimination of AUC in the training and validation cohorts which was 0.7820 (95% CI: 0.7254-0.8439) and 0.8432 (95% CI: 0.7588-0.9151), respectively. At the cut-off value of 0.5, it had a sensitivity and specificity of 70.75% and 66.33% in the training cohort and 76.09% and 73.91% in the validation cohort, respectively. With suitable calibration accuracy shown in calibration curves, decision curve analysis indicated high clinical value in predicting pneumonia probability in SARS-CoV-2-infected patients. The probability of pneumonia predicted by the model was positively correlated with the actual pneumonia classification. This study has developed a pneumonia risk prediction model that can be utilized for diagnostic purposes in predicting the probability of pneumonia in patients infected with SARS-CoV-2.

Arterial partial pressure of oxygen and procalcitonin combined with ROX index predict the timing of tracheal intubation in patients with acute severe pancreatitis

To investigate the efficacy of arterial partial pressure of oxygen (PaO2), procalcitonin (PCT) combined with ROX index in predicting the timing of tracheal intubation in patients with acute severe pancreatitis (SAP). A case-control study was conducted. A total of 148 patients with SAP admitted to Hunan Provincial People's Hospital from January 2019 to December 2022 were selected as the research objects. According to whether endotracheal intubation was used after admission during hospitalization, the patients were divided into the intubation group (102 cases) and non-intubation group (46 cases). Gender, age, white blood cell count (WBC), lymphocyte count (LYM), platelet count (PLT), C-reactive protein (CRP), hemoglobin (Hb), PCT, PaO2, arterial partial pressure of carbon dioxide (PaCO2), arterial bicarbonate ion (HCO3-) 1 day after admission, arterial lactic acid (Lac), lactate dehydrogenase (LDH), heart rate (HR), respiratory rate (RR), pulse oxygen saturation (SpO2), oxygenation index (PaO2/FiO2), blood pressure, worst ROX index (ROX index = SpO2/FiO2/RR) within 30 minutes of admission and 30 minutes before intubation of the two groups were measured. Multivariate Logistic regression was used to analyze the independent risk factors for the timing of endotracheal intubation in patients with SAP. The receiver operator characteristic curve (ROC curve) was used to determine the optimal predictive cut-off value for endotracheal intubation. There were no significant differences in age, gender, WBC, LYM, CRP, Hb, LDH, HR and blood pressure at admission between the two groups. The PLT, Lac, PCT and RR in the intubation group were significantly higher than those in the un-intubation group, and HCO3-, PaO2, SpO2, PaO2/FiO2, the worst ROX index within 30 minutes after admission and 30 minutes before intubation were significantly lower than those in the non-intubation group (all P < 0.05). Logistic regression analysis showed that the worst ROX index within 30 minutes before intubation was the largest negative influencing factor for the timing of tracheal intubation in SAP patients [odds ratio (OR) = 0.723, 95% confidence interval (95%CI) was 0.568-0.896, P = 0.000], followed by PaO2 (OR = 0.872, 95%CI was 0.677-1.105, P < 0.001). PCT was the positive influencing factor (OR = 1.605, 95%CI was 1.240-2.089, P < 0.001). ROC curve analysis showed that the area under the ROC curve (AUC) of PaO2, PCT, the worst ROX index within 30 minutes before intubation and the combination to evaluate the tracheal intubation time of patients with SAP were 0.715, 0.702, 0.722 and 0.808, the sensitivity was 78.1%, 75.0%, 81.5% and 89.3%, the specificity was 66.7%, 59.0%, 73.2% and 86.4%, and the best cut-off value was 60.23 mmHg (1 mmHg ≈ 0.133 kPa), 2.72 μg/L, 4.85, and 0.58, respectively. The AUC of the combination of PaO2, PCT and the worst ROX index within 30 minutes before intubation predicted the timing of tracheal intubation in patients with SAP was significantly greater than using each index alone (all P < 0.01). The worst ROX index within 30 minutes before intubation combined with PaO2 and PCT is helpful for clinicians to make a decision for tracheal intubation in patients with SAP.

Left atrial function index predicts poor outcome in STEMI patients treated with percutaneous coronary intervention

The prognostic value of the left atrial function index (LAFI) in acute ST segment elevation myocardial infarction (STEMI) patients treated with percutaneous coronary intervention (PCI) is unknown. This study sought to determine whether the LAFI predicts prognosis in STEMI patients treated with PCI. Patients with newly diagnosed STEMI who were treated with PCI in Hunan Provincial People's Hospital from March 2020 to October 2020 were prospectively enrolled. All patients underwent transthoracic echocardiography at baseline and follow-up. The endpoint events included rehospitalization due to unstable angina, nonfatal myocardial infarction, rehospitalization due to heart failure and cardiovascular death. A total of 156 STEMI patients treated with PCI were studied with a median follow-up of 14 months. Forty-eight patients had endpoint events. The LAFI had the highest area under the receiver operating characteristic curve (AUC) predicting the endpoint events, with an AUC of 0.90 (95% CI 0.84–0.94). Multivariate Cox analysis demonstrated that only the LAFI (HR: 0.91, 95% CI 0.87–0.96, P < 0.0001) was independently predictive of endpoint events. Kaplan‒Meier survival curves showed that patients with an LAFI ≤ 42.25 cm/cc/m2 had more events than patients with an LAFI > 42.25 cm/cc/m2 (HR: 19.15, 95% CI 8.90–41.21, P < 0.001). The LAFI is a strong and independent predictor of events in STEMI patients treated with PCI.

The role of bronchoscopy in slide tracheoplasty in children

To study the role of bronchoscopy in slide tracheoplasty. A retrospective analysis was conducted on the diagnosis and treatment of four children with tracheal stenosis admitted to Hunan Provincial People's Hospital from 2017 to 2020. The role of bronchoscopy was summarized in the preoperative evaluation, intraoperative positioning and measurement, and postoperative wound evaluation and treatment during slide tracheoplasty. Bronchoscopy evaluation before slide tracheoplasty showed that 3 of the 4 children had complete trachea rings, 2 had pulmonary artery sling, and 2 had multiple stenosis. Slide tracheoplasty was performed in the hospital on 3 children, and the midpoint of the stenosis segment was judged under bronchoscopy, and the length of the stenosis segment was measured, which assisted in the resection of the stenosis segment of the trachea. The pathogens were identified by lavage after the surgery. One child who developed scar traction 9 months after slide tracheoplasty in another hospital was improved by interventional treatment under bronchoscopy. Mucosal changes were found under bronchoscopy in 2 children 4 days after surgery, and the treatment plan was adjusted. One month after surgery, 2 children had granulation hyperplasia, which was improved by cryotherapy under bronchoscopy. One child abandoned treatment due to anastomotic necrosis and died. Three survivors were followed up for over 6 months with good prognosis, but all had tracheobronchial malacia. Bronchoscopy can be used for the management of slide tracheoplasty in children with tracheal stenosis, which is helpful to postoperative rehabilitation and follow-up.

Alveolar rhabdomyosarcoma with multiple bone marrow infiltration

A 15-year-old girl visited Hunan Provincial People's Hospital (The First Affiliated Hospital of Hunan Normal University, Changsha, China) in November, 2022, because of a 13-day history of lower back and leg pain. She had no previous medical history. Her symptoms did not alleviate after treatment with intravenous fluids and analgesics in a local hospital. Abdominal tenderness and muscle spasm were detected on physical examination. Laboratory test results showed a white blood cell count of 14·03 × 109 per L (reference range 4–10 × 109 per L), a neutrophil count of 9·6 × 109 per L (reference range 1·3–8·3 × 109 per L), a monocyte count of 0·78 × 109 per L (reference range 0·14–0·6 × 109 per L), and a platelet count of 85 × 109 per L (reference range 100–300 × 109 per L). PET-CT scan showed extensive and diffuse bone marrow involvement and a hypermetabolic subcutaneous nodule in the chest wall (figure). Therefore, lymphoma was considered as the initial diagnosis.
