Effect of Vaginoscopy versus Conventional Hysteroscopy on Pain, Complications, and Patient Satisfaction in Patients with Endometrial Polyps.

Background Hysteroscopy is considered the gold standard for diagnosing intrauterine pathology. Traditional hysteroscopy requires the placement of a vaginal speculum and cervical forceps, which are large in diameter, causing discomfort and pain to the patient and even causing vagal reflexes. Aims To investigate the impact and clinical value of vaginoscopy versus conventional hysteroscopy on pain, complications, and patient satisfaction in patients with endometrial polyps and to analyse the advantages of clinical application of vaginoscopy examination. Materials and Methods One hundred and twenty-five patients with endometrial polyps treated in our hospital from May 2021 to December 2021 were selected for this study and divided into 52 cases in the hysteroscopy group and 73 cases in the vaginoscopy group according to the random remainder grouping method. Conventional hysteroscopy was used, and in the vaginoscopy group, vaginoscopy was performed. The impact of pain, complications, patient satisfaction, and clinical value of the two groups was observed and compared. Results The time taken for the examination varied between the different hysteroscopic methods, with the hysteroscopy group taking the longest time compared to the vaginoscopy group (P < 0.01). The VAS scores immediately after the examination and 30 minutes after the examination were both significantly higher in the hysteroscopy group than in the vaginoscopy group (P < 0.01). The difference in NPY, PGE2, and 5-HT after the pain-causing mediator intervention was significantly better in the vaginoscopy group than in the hysteroscopy group. The difference in the incidence of complications such as abortion syndrome, cervical laceration, uterine perforation, and haemorrhage after treatment was significantly lower in the vaginoscopy group than in the hysteroscopy group. In the vaginoscopy group, the satisfaction rate was 91% significantly higher than that of the hysteroscopy group (P < 0.05). Conclusion The vaginoscopy technique shortens the examination and treatment time, reduces patient pain, improves patient compliance, reduces the use of preintervention drugs and anaesthetics, and reduces complications.

After treatment, the amount of urine leakage in the experimental group was less than that in the control group, and the difference was statistically significant (<italic>P</italic>&lt;0.05). 2) After treatment, the irritation symptoms, stress symptoms, discomfort symptoms and the total scores of UDI-6 were found significantly lower in the experimental group than in the control group (<italic>P</italic>&lt;0.05). These scores were significantly lower in both groups after treatment (<italic>P</italic>&lt;0.05), except for the discomfort symptoms in the control group. 3) In the dimensions of limited behavior, psychological impact, social barriers and total scores of I-QOL, the intergroup, time and intergroup, and time interaction effects of the two groups were statistically significant (<italic>P</italic>&lt;0.05). After treatment and at follow-up, the scores of overall I-QOL and limited behaviors, psychological impacts, social barriers were improved in both groups (<italic>P</italic>&lt;0.05), and the experimental group improved more than the control group (<italic>P</italic>&lt;0.05). At follow-up, the score of social barriers in the experimental group was higher than that after treatment (<italic>P</italic>&lt;0.05), but there were no significant differences in the scores of overall I-QOL and other dimensions compared with those after treatment (<italic>P</italic>&gt;0.05). <bold>Conclusion</bold> Traditional Chinese medicine hot pressing can improve the symptoms of urinary leakage in female patients with SUI and enhance the quality of life, which is better than conventional rehabilitation and nursing.

Evaluation of staff satisfaction after the implementation of a daily goals sheet in the routine work of an oral outpatient department and its influence on work efficiency

BackgroundIn March 2021, the supervision group of our hospital inspected the daily work of the outpatient department in the branch and found many problems in the process, such as an excessive number of daily check-up forms, nurses’ confusion regarding the daily check-up process, and the omission of daily check-up items. Therefore, focusing on these problem, our hospital established a quality improvement team to conduct a status survey and perform this study. This study evaluated the feasibility, availability and sustainability of using a daily goals sheet in the routine work of a stomatological outpatient department and investigated the satisfaction of the nursing staff with the sheet.MethodsAfter determining the theme of this study through the status survey, 60 nurses were randomly selected and divided into an experimental group and a control group by a random grouping method. Then, the study was divided into two stages: Applying the PDCA cycle method and following the MECE (Mad Exclusive, Collectively Exhaustive) principle to design, manufacture and apply the daily goals sheet. After the expert group performed Stage one, an analysis of work efficiency and routine omissions and a staff satisfaction survey were carried out. The results of the groups either using the daily goals sheet (n = 30) or not (n = 30) were analysed and compared.ResultsThe average work time of the daily goals sheet group was 15.20 ± 1.70 min, and that of the nondaily goals sheet group was 25.30 ± 2.70 min (P < 0.001). The omission rate was 0% in the daily goals sheet group and 16.67% in the nondaily goals sheet group. Staff satisfaction with the use of the daily goals sheet was high.ConclusionThe daily goals sheet can make routine work more efficient and convenient in a stomatological outpatient department. It is recommended for use in stomatological outpatient departments or hospitals.

Overwork Affects Extracellular Matrix of Arterial Vessel Wall in Rats

Objective To explore the effect of overwork (OW) on extracellular matrix of arterial vessel wall in rats. Methods Random number grouping method was employed to assign 18 Sprague-Dawley rats into three groups(n=6):the control group(no special treatment),group OW(forced swimming twice a day for 15 days),and sleep deficiency(SD)+OW group(in addition to forced swimming twice a day,the rats were put on the platforms in water to limit sleep for 15 days).On the 16th day,the abdominal aorta and common carotid artery were collected after blood sampling from heart under deep anesthesia.A part of the abdominal aorta sample was taken for Masson staining of collagen fiber,and Verhoeff-Van Gieson staining was carried out for the elastic fiber of common carotid artery.Image J was employed for the quantitative analysis of collagen fiber and elastic fiber content.The expression of collagen 1(Col-1) protein was quantified by immunohistochemistry and the ultrastructure of vascular matrix was examined by transmission electron microscopy.The other part of the abdominal aorta sample was used to determine the mRNA levels of matrix metalloproteinase(MMP)-1,MMP-2,MMP-9,tissue inhibitor of metalloproteinases-1(TIMP-1),and Col-1 by quantitative real-time polymerase chain reaction. Results Compared with that in control group,the content of collagen fiber in groups OW and SD+OW had no significant change(all P>0.05);the content of elastic fiber in groups OW and SD+OW decreased(all P<0.001) and had no significant difference between each other(P>0.05).The vascular vessel wall of group OW showed slight fiber breakage,while that of group SD+OW presented wormhole-like or spongy fiber fragmentation.The mRNA levels of MMP-1 and MMP-2 in groups OW and SD+OW had no significant difference between each other(P>0.05) but were higher than that in control group(all P<0.001).The mRNA levels of MMP-9 and TIMP-1 had no significant difference among the three groups(all P>0.05).Groups OW and SD+OW had lower mRNA level(all P<0.001) and protein level(all P<0.001) of Col-1 than control group,while the mRNA and protein levels of Col-1 had no significant difference between groups OW and SD+OW(P>0.05). Conclusion OW can reduce the content of Col-1 and elastic fibers in the extracellular matrix of arterial vessels,destroy the elastic lamina of vascular wall,up-regulate the expression of MMP-1 and MMP-2,thereby injuring arterial vessels.

Analgesic effects of different concentrations of ropivacaine in transversalis fascia plane block during laparotomy

ObjectiveTo explore the analgesic effects of different concentrations of ropivacaine in transversalis fascia plane (TFP) block during laparotomy.MethodsNinety patients who underwent laparotomy admitted to our hospital from March 2019 to March 2020 were selected as the study subjects and were divided equally into a low concentration group, a medium concentration group, and a high concentration group according to the randomized grouping method. The low concentration group adopted 0.4% ropivacaine 40 ml, the medium concentration group was given 0.5% ropivacaine 40 ml, and the high concentration group was given 0.6% ropivacaine 40 ml. The hemodynamic indexes and the incidence of adverse reactions in the two groups were compared. The Numerical Rating Scale (NRS) was used to assess the postoperative pain in the three groups, the Bruggrmann comfort scale (BCS) was used to assess the comfort level in the three groups, and the Mini-mental State Examination (MMSE) was used to evaluate the postoperative cognitive function of the three groups of patients.ResultsThe mean artery pressure (MAP) and heart rate (HR) levels at T1 and T2 were significantly lower in the medium concentration group than in the other two groups (P < 0.05). The low concentration group had a significantly higher NRS score at T2 than the medium concentration group and the high concentration group (P < 0.05). A significantly higher BCS score was observed in the high concentration group than the other two groups (P < 0.05). There were significantly higher Ramsay scores and MMSE scores in the medium concentration group than in the low concentration and high concentration groups (P < 0.05). The overall incidence of adverse reactions of the high concentration group was significantly higher than that of the low concentration group (P < 0.05), but showed similar results with the medium concentration group.ConclusionThe medium concentration group exhibits a better analgesic effect than the low concentration group and higher safety than the high concentration group. Therefore, the use of medium concentration ropivacaine in TFP block may provide a referential basis for clinical treatment.

Positive impacts of e-aid cognitive behavioural therapy on the sleep quality and mood of nurses on site during the COVID-19 pandemic.

ObjectiveTo investigate the positive impact of e-aid cognitive behavioural therapy on the sleep quality, anxiety, and depression of nurses on site during the COVID-19 pandemic.MethodsNurses on site at the Tianjin Medical University General Hospital Airport Site experiencing insomnia, anxiety and depression during the COVID-19 prevention and control period, from February 2020 to April 2021, were selected and divided into either an e-aid cognitive behavioural therapy (eCBT-I) group or a control group using a randomized grouping method. The eCBT-I group was given standard eCBT-I for 6 weeks; the control group did not get any intervention. The Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI) were used to evaluate the sleep quality of the subjects. The Generalized Anxiety Disorder 7-item (GAD-7) and the Patient Health Questionnaire (PHQ-9) were used to assess the subjects’ anxiety and depression. Changes in sleep quality, anxiety and depression before and after treatment were compared between the two groups.ResultsOf 118 nurses randomized, the PSQI and ISI scores within the eCBT-I group (n=60) were significantly lower after treatment (5.9 ± 3.9, 6.7 ± 4.5) than before treatment (10.4 ± 3.5, 12.4 ± 4.7) (p <0.05). Compared to the scores of the control group (n=58) (9.1 ± 3.9, 10.6 ± 4.1), the PSQI and ISI scores in the eCBT-I group (5.9 ± 3.9, 6.7 ± 4.5) were lower after treatment (p <0.05). The GAD-7 and PHQ-9 scores in the eCBT-I group were all lower after treatment (3.7±3.4, 4.2±4.1) than before treatment (6.7±4.9, 7.7±5.1) (p <0.05). Compared with subjects in the control group (7.1±5.6, 7.3±5.1), subjects in the eCBT-I group (3.7±3.4, 4.2±4.1) had lower scores on the GAD-7 and PHQ-9 scales after treatment (p <0.05).ConclusioneCBT-I improved the sleep quality of frontline nurses during the COVID-19 prevention and control period and relieved anxiety and depression.

Reliability analysis of fatigue data using non‐probabilistic convex modelling approach

AbstractLife scatter should be estimated when performing fatigue reliability analysis for a structure. Probabilistic approaches require a large amount of statistical information, which is usually unrealistic because of the test condition constraints. In this study, a non‐probabilistic convex modelling approach was proposed for estimating E‐N scatter. A random grouping method is employed to enlarge the sample size for uncertainty quantification. The limited experimental data of AISI H11 was used for E‐N scatter estimation. The results show that non‐probabilistic convex modelling approach is more competitive in practical engineering application, especially for high‐reliability based optimization design.

Effects of Damage Control Resuscitation Combined with Alanyl Glutamine on Complications and Survival in Sufferers with Severe Multiple Trauma

To explore the clinical value of damage control resuscitation combined with alanyl glutamine in the treatment of severe multiple trauma sufferers is the main objective of the study. A total of 120 sufferers with injury severity score≥16 points of severe multiple trauma who were admitted to our hospital from November 2019 to February 2022 were selected and separated into blank group and intervention group (group J and group M) according to random grouping method with 40 people in each group. The general information, clinical indicators, thromboelastography indicators, complications and survival rate of the sufferers were recorded. The operation time, coagulation function time, hospitalization time, body temperature recovery time, prothrombin time, activated partial thromboplastin time, blood loss, total fluid input and mortality of the study subjects were statistically significant. The coagulation indexes of the three groups of research subjects before blood transfusion were not statistically significant and the coagulation indexes of the intervention group (J and M groups) after blood transfusion were statistically significant compared with the blank group. Damage control resuscitation combined with alanyl glutamine significantly reduces complication rates in sufferers with severe polytrauma, thereby improving the survival rate of sufferers after surgery.

Optimized matching between students of the automation major and their specialized project design assignment

Specialized project design (SPD) is a compulsory course for most of the engineering students in China. A SPD course requires teamwork of students. It is therefore an important issue about how to group students in a more reasonable form to increase students’ interest in the course and improve their performance. However, at present, it remains a challenge to quantitatively assess the effectiveness of group teaching and optimize group teaching through state-of-the-art methods such as artificial intelligence. In this study, we propose a qualitative analysis method to study the group teaching of students through teacher’s subjective evaluation of different aspects of students’ abilities. In particular, the proposed method is a background-based grouping method which takes into account the students’ scores attained in prerequisite courses of a SPD course and realized by a genetic algorithm. Results of our experiment demonstrate that, compared with the conventional random grouping method, the proposed method improves the students’ average scores in all eight SPD topics by 2.5 in the grade 2016 and 1.875 in grade 2017, respectively (the total score is 100). Therefore, our findings strongly support that grouping students based on their strengths (for example, the courses they are good at) can enhance students’ interest in the SPD course and thereby improve students’ SPD performance.

Influences of gas explosion on acute blast lung injury and time phase changes of pulmonary function in rats under real roadway environment

Objective: The aims of this study were to investigate the effect of gas explosion on rats and to explore the pulmonary function alterations associated with gas explosion-induced acute blast lung injury (ABLI) in real roadway environment. Methods: In April 2018, the large coal mine gas explosion test roadway and explosion test system were used to simulate the real gas explosion roadway environment, fixed the cage and set the explosion parameters. 72 SD rats, male, SPF grade, were randomly divided into nine groups by completely random grouping method according to their body weight: control group, close range group (160 m) , and long range group (240 m) . In each group, there were wound groups (24 h group and 48h group, 8/group, total 48 in six groups) and no wound groups (8/group, total 24 in three groups) . Except for the control group, the other groups were placed in cages at different distances under anesthesia, the experiment of gas explosion was carried out by placing the rats in a position that could force the lungs. The changes of respiratory function of the rats in the non-invasive group were monitored with pulmonary function instrument at 2 h, 24 h, 48 h, 72 h and 168h after the explosion, and were killed under anesthesia 7 days later; the rats in invasive groups were anesthetized and killed at 24 h, 48 h and 168 h, respectively. Gross observation, lung wet-dry ratio and lung histopathology were performed. Results: Compared with the control group, f (respiratory frequency, f) , MV (minute ventilation, MV) , PEF (peak expiratory flow rate, PEF) , PIF (peak inspiratory flow rate, PIF) and EF50 (1/2 tidal volume expiratory flow, EF50) of rats in the close and long range groups decreased significantly after gas explosion 2 h. PAU (respiration pause, PAU) , Te (expiratory time, Te) , Ti (inspiratory time, Ti) and Tr (relaxation time, Tr) were significantly increased (P<0.05) . After 48 h, TV (tidal volume, TV) , Penh (enhanced respiration pause, Penh) , PAU, and PIF of rats in the long range group were significantly increased (P<0.05) . After 72 h, MV in the long range group was significantly decreased (P<0.05) . Compared with the control group, Penh, PAU, Ti and Te were significantly decreased after 168 h in the close and long range groups, with statistical significance (P<0.05) . At the same time, the body weight of rats in different range groups was significantly decreased (P<0.05) . In addition, both HE staining and routine observation of lung tissues of rats in different range groups showed that gas explosion caused pulmonary edema, obviously congested pulmonary capillaries, a large number of inflammatory cells and infiltrated red blood cells. Conclusion: Gas explosion in real roadway environment can cause the change of respiratory function phase and lung tissue damage in rats, suggesting that the model of gas explosion-induced ABLI has been initially established successfully, which would provide a basis for further study on the pathogenesis of ABLI.

Modeling kaolinite electrical features under pressure using Pseudo Random Renormalization Group method at the audio frequency range

Few reports are displayed on relation between electrical characteristics of rocks and pressure. The objective of this article is the interpretation and modeling of experimental kaolinite specimens under various pressures (0- ~4.5 Kb, at ~50% humidity), and frequency (10 Hz - 10 kHz). Complex impedance measurements were performed for samples. At low pressure range (≤1 Kb); the reliance of the experimental capacitance and conductance on the pressure displays a considerable dependence on the applied pressure. Constant conductances are present at higher pressures. With rising pressure the capacitance decreases. These behaviors are interpreted by percolation theory. With the rise of pressure, the pore spaces decrease and conducting paths between grains increase. The behavior of capacitance and conductance with frequency is comparable with other reports as it will be discussed. Due to existence of water, it was supposed there is impedance at the kaolinite grain surfaces. Also, it was supposed the presence of charge movement and chemical reaction at surface grains. Renormalization group model as a member of the percolation group methods was used to interpret and model experimental data. We developed a model using four phases to analyze the probable deviations in electrical features that may control pressure.

Objective: To observe the clinical efficacy of vitrectomy combined with foveal-sparing circular internal limiting membrane peeling with the central fovea reserved in patients with high myopic foveoschisis. Methods: Case-control study. A total of 72 patients (86 eyes) with foveoschisis due to high myopia who underwent vitrectomy combined with internal limiting membrane peeling in Lishui Municipal Central Hospital of Zhejiang Province from June 2016 to May 2017 were enrolled, including 18 males (18 eyes) and 54 females (68 eyes), aged (50.5±8.9) years. The patients were randomly divided into the observation group (34 cases, 43 eyes) and the control group (38 cases, 43 eyes) using a random number table and random number residual grouping method. Vitrectomy was performed in all patients. In the control group, the limiting membrane in the macular area was removed during surgery. In the observation group, the foveal annular internal limiting membrane was preserved during surgery. In severe cases, cataract extraction was performed. Results: In the observation group, the mean central foveal thickness (CFT) on optical coherence tomography was (723.49±130.95) μm preoperatively and decreased to (286.33±210.73) μm postoperatively, and the difference had statistical significance (t=17.059, P=0.000). In 39 eyes with complete or partial healing of the foveal split, the best corrected visual acuity (BCVA) was (0.99±0.40) logMAR before the treatment and increased to 0.68±0.24 after the treatment, and the difference had statistical significance (t=7.585, P=0.000). In the control group, the mean CFT was (726.98±140.62) μm and (297.88±241.56.) μm before and after the treatment, respectively, and the difference had statistical significance (t=16.271, P=0.000). In 38 eyes with complete or partial healing of the foveal split, the BCVA increased from preoperative 1.04±0.47 to postoperative 0.69±0.21, and the difference had statistical significance (t=6.707, P=0.00).

The water quality, contaminant migration characteristics, and emissions quantity of pollutants in the basin would have a great impact on aquatic creatures, agricultural irrigation, human life, and so on. In the aquaculture industry, because water colour can reflect the species and number of phytoplankton in the water, the water quality type can be obtained by analysing the colour of the aquaculture water using image processing techniques. Therefore, this study proposes an intelligent monitoring approach for water quality. The critical features of water colour images are extracted, and then using the machine learning methods, an intelligent system for water quality monitoring is established based on the fused random vector functional link network (RVFL) and group method of data handling (GMDH) model. The proposed approach presents a superior performance relative to other state-of-the-art methods, and it achieves an average predicting accuracy of 96.19% on the feature dataset. Experimental findings demonstrate the validity of the proposed approach, and it is accomplished efficiently for the monitoring of water quality.

Application of Artificial Intelligence-based predictive methods in Ionic liquid studies: A review

Comprehensive experimental investigation and accurate predictive models are required to understand the dynamics in Ionic liquid (IL) properties. Examples of these predictive models are empirical correlations, Quantitative Structure Property Relationship (QSPR) and Machine Learning (ML). In this study, we reported the application of various ML models for predicting thermo-physical properties of ILs. Our study showed that these ML models could be categorized into conventional and hybrid models. These conventional models include Artificial Neural Networks (ANN), Least Square Support Vector Machine (LSSVM) and Adaptive Neuro-Fuzzy Inference System (ANFIS). Meanwhile, the hybrid models consist of random forest, gradient boosting, and group method of data handling. We provided an overview of these ML models and optimization methods such as genetic algorithm, particle swarm algorithm, and Coupled Simulated Annealing (CSA) algorithm, and their applications in IL studies. We observed that ANN, LSSVM, and ANFIS represent the three most frequently used ML approaches in predicting the various properties of ILs among the models discussed. The investigation revealed that the ANN approach is most widely used, while the studies involving the solubility of gases (H2S and CO2) represent the most common problems related to ML application in IL studies. However, the combination of conventional ML and optimization algorithms such as LSSVM-CSA gives better accuracy compared to ANN in most applications. It is noteworthy that system parameters (temperature and pressure) and critical properties (critical temperature and critical pressure) are the key thermo-physical that depicts the phase behavior of any ILs. Finally, to generalize MLs methods to certain ILs based on similarity in cations and anions, it is important to represent the molecular descriptions of the liquid as one of the property predictors.

Impact of ISBAR Communication Training on Interpersonal Communication and Teamwork of Residents in General Practice Standardized Training

Interpersonal communication and teamwork is one of the training objectives of standardized training for residents. The ISBAR (Identify, Situation, Background, Assessment, Request) communication training model can effectively improve physicians’ clinical communication skills and teamwork ability. Our research aims to explore the impact of the ISBAR communication training on the interpersonal communication and teamwork of residents in general practice standardized training. A total of 92 general practitioners (GP) who participated in the Standardized Residency Training in the First Affiliated Hospital of Xi’an Jiaotong University in September 2018 were randomly recruited and divided into observation group（n=46） and control group（n=46） using simple random grouping method. GP in the observation group was trained by the ISBAR communication training model, whereas GP in the control group was trained by the traditional clinical education model. Six different scales were used to assess the interpersonal communication ability and teamwork ability of the two groups at different time points. After two weeks of training，the scores of interpersonal communication ability and teamwork ability in the observation group were higher than those in the control group（P&lt;0.05）. ISBAR communication training model may significantly improve the interpersonal communication skills and teamwork ability of residents in general practice standardized training.
