Auto interpretable depth learning model to analyze the hemodynamic changes and pulmonary complications in laparoscopic gynecologic tumor surgery with nalmefene hydrochloride combined with general anesthesia.

In this work, based on intelligent computing, the biological signals of patients were analyzed to investigate the hemodynamic changes and pulmonary complications of Nalmefene Hcl combined with general anesthesia (GA) in laparoscopic gynecological tumor surgery (GTS). Eighty computer-aided GTS patients were randomly divided into a control group (n = 40) and an observation group (n = 40). Biomedical electrocardiogram (ECG) signals were detected by wavelet neural network in all patients undergoing laparoscopic gynecological tumor surgery and were computerized according to the android interface definition language model (AIDL). GA was used during surgery. The observation group was injected intravenously with 0.2 μg/kg naproxenacin hydrochloride after operation. The control group was given 1 mL 0.9% sodium chloride solution after operation. Mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), pulse oxygen saturation (SPO), coma score, and adverse reactions (AR) were compared between the two groups at 10, 20, and 30 minutes after wakefulness. The hemodynamic parameters between the two groups were compared. Serum urocholine (URO) and creatinine (Cre) levels were analyzed in patients without complications. ECG waveform based on wavelet neural network has a high recognition rate and strong generalization ability. 37 patients in the observation group recovered within 10 minutes after surgery, and the recovery rate at 30 minutes was 95%. 30 patients in the control group awoke 10 minutes after the operation, and the recovery rate at 30 minutes m-AR was 75%. The average abstract windows toolkit (AWT) of the observation group and control group was 11.87 ± 5.78 min and 16.46 ± 5.32 min, respectively, and the difference was significant (p < 0.05). There were significant differences in HR, systolic blood pressure (SBP), and diastolic blood pressure (DBP) between the observation group and the control group during the extubation (p < 0.05). Blood gas indexes PaO2, PvO2, PaCO2, and PvCO2 in the observation group were significantly different from those in the control group half an hour after the operation and half an hour after pneumoperitoneum (p > 0.05). Intelligent computational biological signal detection was beneficial to the development of surgery. Nalmefene Hcl combined with GA on the basis of the AIDL model has a significant effect on the awakening of GTS patients and can shorten sleep time. Patients with underlying cardiac disease were more likely to develop postoperative lung complications.

ПРОГНОЗ НАСТУПЛЕНИЯ ЗНАЧИМЫХ ИШЕМИЧЕСКИХ СОБЫТИЙ И ЛЕТАЛЬНОГО ИСХОДА У БОЛЬНЫХ ИНФАРКТОМ МИОКАРДА НА ФОНЕ ХРОНИЧЕСКОЙ ОБСТРУКТИВНОЙ БОЛЕЗНИ ЛЕГКИХ

Introduction. Myocardial infarction remains significant due to its high prevalence and disability. Of particular importance is the prediction of the risk of adverse events in myocardial infarction patients with cardiorespiratory comorbidity, in particular with chronic obstructive pulmonary disease. It can be assumed that endogenous intoxication syndrome can be considered as a predictor of life-threatening events (repeated myocardial infarction, stroke) and lethal outcome in patients with myocardial infarction against chronic obstructive pulmonary disease. Aim. The aim is to determine the probability of combined endpoint development (repeated myocardial infarction, stroke, lethal outcome) in patients with myocardial infarction against chronic obstructive pulmonary disease during 12-month follow-up depending on gender-anamnestic and clinical-functional characteristics. Material and methods. We examined 325 patients with myocardial infarction - 195 patients with myocardial infarction against chronic obstructive pulmonary disease and 130 patients with myocardial infarction without chronic obstructive pulmonary disease (comparison group). As markers of endogenous intoxication syndrome, we studied middle weight molecules, hematological intoxication indices, blood gas indices, apoptosis, protein and lipid peroxidation and antioxidant protection, inflammation and renal function. Statistical data processing was performed using SPSS 26.0 software package. Results and discussion. Two-stage cluster analysis resulted in four clusters characterizing the type of endogenous intoxication syndrome: «polymarker-retentive», «necrotic- inflammatory», «hypoxic-inflammatory» and a cluster with no endogenous intoxication syndrome. The polymarker- retentive type of endogenous intoxication syndrome prevailed among patients with myocardial infarction against chronic obstructive pulmonary disease. Recurrent myocardial infarction, stroke and mortality constituted the combined endpoint. A decision tree was constructed to determine the probability of developing the combined endpoint in patients with myocardial infarction against the background of chronic obstructive pulmonary disease during the 12-month follow-up. It was found that the most significant predictors of combined endpoint occurrence are polymarker-retentive type of endogenous intoxication syndrome, the presence of acute infarction period complications and pronounced bronchoobstruction (degree 3-4). Conclusion. The constructed decision tree allows to stratify patients with high risk of repeated infarction, stroke and lethal outcome during the first year of follow-up after myocardial infarction against chronic obstructive pulmonary disease without increasing economic costs, which promotes optimization of treatment and secondary prevention in this category of patients.

Comparison of Venous Blood Gas and Biochemical Parameters in Sunda Pangolin (Manis javanica) and Chinese Pangolin (Manis pentadactyla) before and after Isoflurane Anesthesia

Venous blood gas analytes are commonly examined in animals, and the results may be important when evaluating the overall health status of an animal. Pangolins are critically endangered mammals, and there is limited information on their physiological reference values in the literature. The aim of this study was to analyze venous blood gas and biochemical parameters before and during isoflurane anesthesia in wild healthy Sunda and Chinese pangolins. The results obtained showed that the blood gas index trends of the two pangolin species before and after isoflurane anesthesia were the same. After anesthesia, the partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), total carbon dioxide (CO2), mean blood bicarbonate (HCO3-), extracellular fluid compartment (BEecf) base excess and the mean blood glucose (Glu) levels of both pangolin species showed a significant increase compared to the pre-anesthesia period. In contrast, the mean blood potassium (K+), lactate (Lac) and mean blood pH levels were significantly lower. No significant differences in the mean blood sodium (Na+) or blood ionized calcium (iCa) levels were observed during anesthesia. This study is important for future comparisons and understanding the health status of this endangered species.

Intravenous lipid emulsion for the treatment of acute lipid-soluble anesthetic drug toxicity in pediatric patients

Clinical studies on the use of lipid emulsions for the treatment of lipid-soluble anesthetic drug intoxication in children are relatively absent. Since children are not shrinking versions of adults, the therapeutic efficacy of lipid emulsions for the treatment of lipid-soluble anesthetic drug intoxication in pediatric patients is uncertain. This paper investigates the therapeutic efficacy and therapeutic mechanism of intravenous lipid emulsion for reversing acute narcotic drug intoxication in pediatric patients based on clinical data from west China Hospital of Sichuan University. The clinical data of 106 pediatric patients with acute lipid-soluble drug intoxication admitted to an inpatient center in the past 3 years were retrospectively analyzed and randomly divided into an observation group and a control group. The cardiac function indexes and blood gas indexes of patients in both groups were compared before and after treatment. After treatment, the left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter (LVEDD) values and plasma B-type natriuretic peptide (BNP) in the observation group were lower than control group, and the left heart ejection fraction (LVEF) was higher than those in the control group, with statistically significant differences (P&lt;0.05). The arterial oxygen saturation (), partial pressure of oxygen () and acid-base (pH) values were higher in the observation group than in the control group, and the partial pressure of carbon dioxide () values were lower than in the control group. And these differences were statistically significant (P&lt;0.05). Therefore, intravenous lipid emulsion has a positive effect in reversing acute fat-soluble anesthetic drug intoxication in pediatric patients, and is effective in promoting recovery of cardiac function, reversing respiratory failure, and improving blood gas indexes. The results of the study demonstrated the effectiveness of intravenous lipid emulsion in reversing pediatric lipid-soluble anesthetic drug intoxication and enrich the clinical research on this issue.

Volume Incentive Spirometry Reduces Pulmonary Complications in Patients After Open Abdominal Surgery: A Randomized Clinical Trial.

To compare the effect of diaphragmatic breathing and volume incentive spirometry (VIS) on hemodynamics, pulmonary function, and blood gas in patients following open abdominal surgery under general anesthesia. A total of 58 patients who received open abdominal surgery were randomly assigned to the control group (n=29) undergoing diaphragmatic breathing exercises and the VIS group (n=29) undergoing VIS exercises. All the participants performed the six-minute walk test (6MWT) preoperatively to evaluate their functional capacity. Hemodynamic indexes, pulmonary function tests, and blood gas indexes were recorded before surgery and on the 1st, 3rd, and 5th postoperative day. The functional capacity was not significantly different between the two groups during the preoperative period (P >0.05). At 3 days and 5 days postoperatively, patients in the VIS group had a significantly higher SpO2 than that in the control group (P <0.05). Pulmonary function test values were reduced in both two groups postoperatively when compared to the preoperative values but improved for three and five days afterward (P <0.05). Of note, the significantly elevated levels of peak expiratory flow (PEF), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio were observed on the 1st, 3rd, and 5th postoperative days in the VIS group compared with those in the control group (P <0.05). Besides, bass excess (BE), and pH values were significantly higher in the VIS group on the 1st postoperative day than those in the control group (P <0.05). Diaphragmatic breathing and VIS could improve postoperative pulmonary function, but VIS exercise might be a better option for improving hemodynamics, pulmonary function, and blood gas for patients after open abdominal surgery, hence lowering the incidence of postoperative pulmonary complications.

The Short and Long Term Consequences of Delayed Cord Clamping on Late Pre-Term Infants.

To explore the effect of delayed cord clamping on preterm infants. A retrospective analysis was conducted using the clinical data of 163 preterm infants with a gestational age of 34-36 weeks + 6 who were admitted to the neonatology department within 2 hours after birth. The blood routine examination indices within 2 hours and at 3-5 days after birth, the biochemical indices and arterial blood gas (ABG) indices within 2 hours after birth, and the hemoglobin level 5-6 months after birth were compared between the early cord clamping (ECC) group and the delayed cord clamping (DCC) group. Compared with the ECC group, the DCC group had significantly higher venous blood levels of red blood cells, hemoglobin, and hematocrit within 2 hours and at 3-5 days after birth. The ABG bicarbonate (HCO3) level within 2 hours after birth was obviously higher in the DCC group than in the ECC group, and the ABG absolute base excess(BE) and lactate levels were lower in the DCC group than in the ECC group (P < 0.05). There was no significant difference between the two groups in the incidence of hypothermia, hypoglycemia, respiratory distress, septicemia, feeding intolerance, polycythemia, and hyperbilirubinemia requiring phototherapy during hospitalization (P > 0.05). Compared with the ECC group, the DCC group had a significantly higher venous blood hemoglobin level 5-6 months after birth. The incidence of anemia in the DCC group was significantly lower than in the ECC group (P < 0.05). Delayed cord clamping can significantly increase the hemoglobin levels of preterm infants at birth and at 5-6 months after birth and can improve the oxygen circulation supply to the organs of such infants. Therefore, delayed cord clamping can improve the prognosis of preterm infants.

Effects of combination treatment with theophylline sustained release tablets and thymalfasin on pulmonary function, immunity, and inflammation in elderly patients with chronic obstructive pulmonary disease and respiratory failure

Purpose: To investigate the effect of combined administration of theophylline sustained-release tablets and thymalfasin on pulmonary function, immunity, and inflammation in elderly patients with chronic obstructive pulmonary disease (COPD) and respiratory failure.&#x0D; Methods: A total of 122 elderly patients in Fujian Geriatric Hospital, Fuzhou, China who suffered from acute attack of COPD with respiratory failure from January 2019 - January 2020 were selected for this study. The patients were divided randomly and evenly into study and control groups. Theophylline sustained-release tablets were administered to subjects in the control group, while theophylline sustained-release tablets and thymalfasin were administered to subjects in the study group. Pulmonary function indicators, viz, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC), blood gas indicators (PaCO2, PaO2, and SaO2), inflammatory factors (sICAM-1, PGE2, and hs-CRP), immune cells (Th17, Treg, and Th17/Treg), as well as exercise ability (the 6 min walking distance test) were evaluated for each group. Adverse reactions were also assessed.&#x0D; Results: There were no significant differences in pulmonary function, blood gas, inflammation, immunity, and exercise ability between the two groups before treatment (p &lt; 0.01). However, all parameters improved significantly for both groups after treatment, with better outcomes for all parameters in the study group. A proportion of (14.75 %) patients in the study group showed adverse events, while 13.11 % of the patients in the control group exhibited adverse effects, meaning that the study group had a slightly but not significantly higher rate of adverse events.&#x0D; Conclusion: The combined administration of theophylline sustained-release tablets and thymalfasin reduces inflammation and improves physical immunity, leading to enhancement of blood gas and pulmonary function in elderly patients with COPD and respiratory failure. However, further clinical trials are required prior to application of this combination therapy in clinical practice.

Hypoxemia in thoracoscopic lung resection surgery using a video double-lumen tube versus a conventional double-lumen tube: A propensity score-matched analysis.

Malposition of the double-lumen tubes (DLTs) may lead to hypoxemia during one-lung ventilation (OLV). Video double-lumen tubes (VDLTs) enable continuous observation of DLT position and avoid displacement. We aimed to investigate whether VDLTs could reduce the incidence of hypoxemia during OLV compared with conventional double-lumen tubes (cDLT) in thoracoscopic lung resection surgery. This was a retrospective cohort study. Adult patients who underwent elective thoracoscopic lung resection surgery and required VDLTs or cDLTs for OLV at Shanghai Chest Hospital from January 2019 to May 2021 were included. The primary outcome was the incidence of hypoxemia during OLV between VDLT and cDLT. Secondary outcomes included bronchoscopy use, the degree of PaO2 decline, and arterial blood gas indices. A total of 1,780 patients were finally analyzed in propensity score-matched cohorts (VDLT vs. cDLT 1:1 n = 890). The incidence of hypoxemia decreased from 6.5% (58/890) in cDLT group to 3.6% (32/890) in VDLT group (Relative Risk [RR]: 1.812, 95% CI: 1.19-2.76, p = 0.005). The use of bronchoscopy was reduced by 90% in VDLT group (VDLT 10.0% (89/890) vs. cDLT 100% (890/890), p < 0.001). PaO2 after OLV was 221 [136.0-325.0] mmHg in cDLT group compared to 234 [159.7-336.2] mmHg in VDLT group, p = 0.003. The percentage of PaO2 decline was 41.4 [15.4-61.9] % in cDLT group, while it was 37.7 [8.7-55.9] % in the VDLT group, p < 0.001. In patients who suffered from hypoxemia, there were no significant differences in arterial blood gas indices or the percentage of PaO2 decline. VDLTs reduce the incidence of hypoxemia and the use of bronchoscopy during OLV compared with cDLTs. VDLT may be a feasible option for thoracoscopic surgery.

Investigation of the efficacy and pharmacological mechanism of Danhong injections for treating chronic obstructive pulmonary disease: A PRISMA-compliant meta-analysis and network pharmacology analysis.

Accumulating evidence supported the clinical efficacy of Danhong injection (DHI) on chronic obstructive pulmonary disease (COPD). It is urgent to summarize the effects of DHI on various outcomes in COPD patients and to elucidate the molecular mechanisms of DHI in treating COPD. Eligible studies were retrieved from 6 databases including China national knowledge infrastructure, Wangfang, VIP, web of science, PubMed, and Embase. The heterogeneity across studies was tested using the I2 statistic and the quality of studies was assessed. The pooled evaluation of outcomes was calculated using a fix- or random-effect model according to the heterogeneity. The underlying mechanism of DHI in treating COPD was analyzed using network pharmacology. A total of 34 eligible studies with a general medium quality were included in the meta-analysis. The pooled data showed that DHI intervention significantly increased clinical efficacy as compared to routine treatment. Meanwhile, our data also revealed that the addition of DHI markedly improved hemorheological indicators, lung function index, arterial blood gas index, and as well as blood coagulation functions. However, the current meta-analysis lacked sufficient data to support the significant effect of DHI on prothrombin time and activated partial thromboplastin time. Network pharmacology found 59 candidate targets of DHI in treating COPD, and enrichment analysis found these targets were associated with lymphocyte proliferation and activation, glucocorticoid receptor signaling, TREM1 signaling, IL-12 signaling and production in macrophages, and aryl hydrocarbon receptor signaling. Multiple core targets including AKT1, TNF, and IL1B, etc. Were identified and might play an important role in the action of DHI against COPD. Taken together, this study suggested that DHI could ameliorate hemorheological indicators, lung function, arterial blood gas, and as well as coagulation functions of COPD patients and elucidate the underlying mechanism of DHI against COPD.

Correlation Between Blood Gas Indicators and Outcome of Status Epilepticus Patients in Prof. Dr. I.G.N.G. Ngoerah General Hospital 2019-2020

Background: Status epilepticus (SE) is an emergency in which immediate and effective care is needed. Metabolic acidosis often occurs after SE. Peripheral vasoconstriction will enhance perfusion and adequacy of oxygenation to the most active metabolic organs which are the brain and muscles, so hypoventilation and hypoxia will occur. Aim: This study aims to present the general description of SE patients in Prof. Dr. I.G.N.G. Ngoerah General Hospital and to analyze the correlation between blood gas indicators and SE patient outcomes. Method: This is a cross-sectional study of SE patients that were admitted at Prof. Dr. I.G.N.G. Ngoerah General Hospital from January 2019 to December 2020 with a consecutive sampling method. The patient’s data were acquired from the medical record and the hospital’s information system. Statistical tests were done by the SPSS program. Results: Hundred eight SE patients are enrolled in this study. The types of seizure are focal seizure (N=55) and general seizure (N=53). There are 51 (47.2%) patients who survived and 57 (52.8%) patients who died during medical care. Thirty-four patients needed intensive care. The duration of care is between 2 to 37 days. Factors related to mortality are comorbidity (p=0.00), renal failure (p=0.05), pneumonia (p=0.00), sepsis (p=0.00), intensive care (p=0.01), longer duration of care (p=0.008), and blood gas analysis abnormality (p=0.011) with 2.7 OR. Conclusion: Blood gas analysis is correlated with worse outcomes in patients with SE. Keywords: blood gas, status epilepticus, outcome

Efficiency and Safety of Laparoscopic Radical Cystectomy for Muscle-Invasive Bladder Cancer, and Postoperative Recurrence.

To evaluate the efficiency of open radical cystectomy (ORC) in relation to laparoscopic radical cystectomy (LRC) for muscle-invasive bladder cancer, and incidence of postoperative recurrence. A total of 90 patients with muscle-invasive bladder cancer admitted to our urology department from January 2019 to May 2022 were included in this study. Using the random number table, the patients were assigned equally to ORC and LRC groups. The perioperative data of the patients were collected and recorded. The outcome indicators comprised erythrocyte pressure and creatinine levels, blood gas analysis, type of urinary diversion, and histopathology of surgically removed tumors. Operation time of LRC was significantly longer than that of ORC, but other perioperative indices of LRC were better than those of ORC (p < 0.05). Hematocrit levels in LRC group were higher than those in ORC group at postoperative 1 day and before discharge (p < 0.05). However, creatinine levels were lower in LRC group than in ORC group at postoperative 1 day and before discharge (p < 0.05). Moreover, LRC resulted in better blood gas indices than ORC (p < 0.05). There were no significant differences in the type of urinary diversion and histopathological results from surgically removed tumor between the two groups (p > 0.05). Patients who received LRC had a lower incidence of complications than those given ORC (p < 0.05). LRC reduced perioperative complications, decreased mean length of hospital stays, and enhanced recovery of gastrointestinal and renal functions. These data suggest that LRC is safer and more efficient than ORC. However, further studies are required prior to clinical application of this procedure.

An optimal dietary sodium chloride supplemental level of broiler chicks fed a corn-soybean meal diet from 1 to 21 days of age.

Sodium chloride (NaCl) is usually added to diets to meet the Na and Cl requirements of broilers in the Chinese poultry industry, but the optimal dietary NaCl supplemental level was not well-established. The present study was conducted to estimate the optimal dietary NaCl supplemental level of broilers fed a corn-soybean meal diet from 1 to 21 days of age. A total of 490, 1-day-old Arbor Acres male broilers were fed a NaCl-unsupplemented corn-soybean meal basal diet (control) and the basal diet supplemented with 0.10, 0.20, 0.30, 0.40, 0.50 or 0.60% NaCl for 21 days. Regression analysis was conducted to evaluate the optimal dietary NaCl level using the best fitted broken-line or asymptotic models. As dietary supplemental NaCl levels increased, average daily gain (ADG), average daily feed intake (ADFI), blood partial pressure of CO2, total CO2, base excess and anion gap, blood concentrations of HCO3, Na and Cl, serum Na concentration, jejunal villus height (VH) and tibia ash content increased linearly and quadratically (P < 0.05), while feed/gain ratio, relative weights of heart, liver and kidney, blood K concentration, serum concentrations of K, uric acid and glucose, and osmotic pressure decreased linearly and quadratically (P < 0.05). The estimates of optimal dietary NaCl levels were 0.20-0.22% based on the best fitted broken-line or asymptotic models (P < 0.0001) of ADG, ADFI and feed/gain ratio, and 0.08-0.24% based on the best fitted broken-line or asymptotic models (P < 0.0001) of blood gas indices, serum parameters, jejunal VH, tibia ash content and organ indices. These results suggested that the optimal dietary NaCl supplemental level would be 0.24% for broilers fed the corn-soybean meal diet from 1 to 21 days of age, which is lower than the current dietary NaCl supplemental level (0.30%) in the Chinese broiler production.

Clinical effect of antibiotic combined with fiber bronchoscope perfusion in treatment of pneumonia after severe cerebral hemorrhage.

To explore the curative effect of antibiotic combined with mucosolvan perfusion under fiber bronchoscope in treatment of pneumonia after severe cerebral hemorrhage. The clinical data of 120 patients with pneumonia after severe cerebral hemorrhage admitted to our hospital from January 2017 to December 2019 were collected. All patients were divided into the lavage group and perfusion group by random number method, with 60 patients in each group. Patients in the lavage group received antibiotics combined with mucosolvan lavage therapy under fiber bronchoscope, while patients in the perfusion group received antibiotics combined with mucosolvan perfusion therapy under fiber bronchoscope. Clinical pulmonary infection score (CPIS), arterial blood gas index, clinical symptom improvement, and hospitalization costs were compared between the two groups before and after treatment. CPIS scores were improved after treatment in both groups (P < .05), and CPIS scores of patients in the perfusion group were lower than those in the lavage group at 3, 5, and 7 days after treatment (P < .05). The blood oxygen saturation and partial arterial oxygen pressure of the perfusion group were all higher than those of the lavage group (P < .05), while the partial carbon dioxide pressure was lower than that of the lavage group (P < .05). In the perfusion group, the duration of cough, adequacy of fever, disappearance of rhonchus in the lungs, and the length of hospital stay were less than those in the lavage group (P < .05). The hospitalization costs of perfusion group were lower than that of lavage group (P < .05). The combination of antibiotics and mucosolvan infusion therapy under fiber bronchoscope can effectively improve the clinical efficacy, reduce the hospitalization cost, and improve the prognosis of patients with pneumonia after severe cerebral hemorrhage.

The patients were assigned to control group (n = 41) and a study group (n = 40). The control patients were treated with Xuebijing injection, i.v., while the study group received a combination of Xuebijing injection and thymosin α1 via the subcutaneous route. Patients’ body temperature, heartbeat, white blood cell count, as well as other parameters, including blood gas indices, serum concentrations of IL-6, TNF-α and C-reactive protein (CRP), as well as well as blood gas indices were determined by enzyme-linked immunosorbent assay (ELISA). Bacterial clearance and therapeutic effectiveness were evaluated pre- and post-treatment.&#x0D; Results: Post-therapy basal temperature, breathing, heartbeat, number of white blood cells and other indices decreased in study patients, relative to control (p &lt; 0.05). Moreover, the levels of hydrogen ion concentration (pH) and arterial carbon dioxide partial pressure (PaCO2) were significantly lower in study group than in control group (p &lt; 0.05). Patients in the study group had lower serum levels of IL-6, TNF-α and CRP, when compared to control group, while bacterial load was significantly reduced in study subjects, relative to controls (p &lt; 0.05).&#x0D; Conclusion: Combined use of thymosin α1 and Xuebijing is significantly effective in the management of patients suffering from ASB. The combination therapy also improves the hemorheological status of patients. Thus, it is a potential therapeutic strategy for ASB.&#x0D; Keywords: Acute bronchopneumonia; Xuebijing; Thymosin α1; Septicemia; Inflammation

Effect of combined treatment with linezolid and ulinastatin on respiratory function and serum inflammatory factors in elderly patients with severe pneumonia

Purpose: To investigate the clinical effect of linezolid in combination with ulinastatin on respiratory function and serum inflammatory factors in elderly patients with severe pneumonia.&#x0D; Methods: Ninety-eight (98) elderly patients with severe pneumonia in Nuclear Industry 416 Hospital (January 2019 - January 2020) were equally randomized into group M and group N. Group M patients received linezolid alone, while those in group N received linezolid in combination with ulinastatin. Indices related to respiratory function such as maximal mid-expiratory flow (MMF), peak expiratory flow (PEF), maximal expiratory pressure (PEmax), maximal inspiratory pressure (Pimax), as well as serum inflammatory factors such as C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α), were determined.&#x0D; Results: Total treatment effectiveness, pulmonary function indexes and arterial blood gas indices were higher in group N, while serum inflammatory factors and CPIS and APACHE II scores were lower, when compared with group M (p &lt; 0.05). The incidence of adverse reactions in both groups was comparable (p &gt; 0.05).&#x0D; Conclusion: Combined use of linezolid and ulinastatin produces marked therapeutic effect in elderly patients with severe pneumonia. It effectively lowers serum inflammatory factor levels, elevates arterial blood gas indices and improves pulmonary function. However, further clinical trials are required prior to its introduction in clinical practice.&#x0D; Keywords: Severe pneumonia; Respiratory function; Serum inflammatory factor; Linezolid; Ulinastatin

Effect of Intensive Nursing Intervention on Blood Gas Index, Lung Function and Prognosis of Elderly Patients with Severe Pneumonia

The effect of high-frequency oscillatory ventilator combined with pulmonary surfactant in the treatment of neonatal respiratory distress syndrome.

Objective:To investigate the efficacy of high-frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) in the treatment of neonatal respiratory distress syndrome (NRDS).Methods:This study is a retrospective clinical study. Seventy-two NRDS neonates were selected as the subjects from November 2019 to November 2020, and divided into observation group (40 cases, HFOV treatment) and control group (32 cases, conventional mechanical ventilation treatment). All cases were treated with PS and comprehensive treatment. The therapeutic effect, arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), Percentage of inhaled oxygen concentration (FiO2), mean arterialpressure, oxygenation index (OI), and complications were compared in the 2 groups.Results:The total effective rate of the observation group was 90.0%, significantly higher than that of the control group. After treatment, the observation group has higher PaO2 levels and lower levels of PaCO2, mean arterial pressure, FiO2, and OI than the control group. There was no significant difference in the incidence of complications between the 2 groups.Conclusion:HFOV combined with PS has a significant effect on NRDS, which can improve the arterial blood gas index without increasing the incidence of complications.

Protective effect of salidroside on lung tissue in rats exposed rapidly to high altitude.

To study the protective effect and mechanism of salidroside on lung tissue of rats exposed rapidly to high altitude. Thirty-six Wistar male rats were randomly divided into blank control group, model control group, Rhodiola rosea capsule (137 mg/kg) group, salidroside low-dose (14 mg/kg), medium-dose (28 mg/kg) and high-dose (56 mg/kg) groups, with 6 rats in each group. After 5 continuous days of drug administration in the plain lab, rats were rapidly moved to 4010 m plateau field lab. After exposure to hypoxia condition for 3 days the blood gas indexes were detected; the serum levels of inflammatory factors were measured by enzyme linked immunosorbent assay (ELISA); the oxidative stress index of lung tissue was measured; the pathological changes of lung tissue were observed by microscopy with hematoxylin and eosin (HE) staining; and the expression of occludin in lung tissues was determined by western blotting. Compared with blank control group, arterial oxygen saturation (SaO 2), arterial oxygen partial pressure (PaO 2), blood pH, standard bicarbonate (SBC) and actual bicarbonate levels in model control group were significantly decreased, and hemoglobin level was significantly increased (all P<0.05). In the model control group, the contents of mast cell protease (MCP) 1, interleukin (IL)-6 and IL-1β were significantly increased, while the contents of interferon-γ were significantly decreased (all P<0.01). The contents of glutathione and total superoxide dismutase in the lung tissues of model control group were significantly decreased, while the content of malondialdehyde was significantly increased (all P<0.01). After Rhodiola rosea and salidroside were given, SaO 2, pH, hemoglobin, SBC and actual bicarbonate were improved compared with the model control group. Compared with the model control group, the Rhodiola rosea group and salidroside groups had different degrees of improvement in the contents of the above inflammatory factors and oxidative stress indexes, and the salidroside groups had better improvement in MCP-1 and IL-6 than the Rhodiola rosea group. HE staining showed that, after the administration of Rhodiola rosea capsules and salidroside at low, medium and high doses, the hypoxic injury was significantly improved, the cell wall gradually became thinner, and the alveolar wall gradually became complete. The expression of occludin in the model control group was lower than that in the blank control group ( P<0.05), while the expression of occludin in the salidroside high-dose group was significantly higher than that in the model control group ( P<0.01). Salidroside can improve the abnormality of blood gas index, hypoxia symptoms and acid-base balance disorder, dysregulation of inflammatory factors caused by hypoxia in rats, and improve lung tissue injury and oxidative stress injury, which has a protective effect on lung tissue injury of rats exposed rapidly to the high-altitude plateau, and the effect is better than Rhodiola rosea capsule on the whole.

Effects of High-Frequency Chest Wall Oscillation Expectoration System on Pulmonary Rehabilitation and Cortisol Function in Patients with Severe AECOPD.

Objective To investigate the effect of high-frequency chest wall oscillatory expectoration system (HFCWO) on pulmonary rehabilitation and cortisol function in patients with severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods The 65 severe AECOPD patients admitted to our hospital from January 2019 to May 2020 were divided into group A with 33 cases and group B with 32 cases by random number table method. After 14 days of intervention, the improvement time of clinical symptoms in the two groups was recorded, and blood gas, lung function, inflammatory, and cortisol function-related indicators were evaluated before and after treatment. Results The remission time of expectoration, pulmonary signs, and hospital stay in group A were significantly shorter than those in group B (P < 0.05). Compared with before treatment, blood oxygen partial pressure (PaO2), forced vital capacity (FVC), forced expiratory volume at 1 s (EFV1), and EFV1/FVC increased significantly; blood carbon dioxide partial pressure (PaCO2), C-reactive protein (CRP), interleukin-6 (IL-6), white blood cell count (WBC), plasma cortisol (COR), and adrenocorticotropic hormone (ACTH) levels were significantly decreased, and the above indicators in group A increased or decreased more significantly than those in group B (P < 0.05); there was no significant difference in tolerance and adverse reactions between the two groups (P > 0.05). Conclusion HFCWO has good pulmonary rehabilitation effect in the treatment of severe AECOPD and can significantly improve the blood gas indexes, inflammation, and cortisol function of patients, which is safe and feasible.
