Objective:To construct an evaluation the index system of entrustable professional activities for resident training doctors in psychiatric department,and to provide reference for formulating training strategies and assessment standards.Entrustable professional activities refers to the ability of trainees to perform and complete spe-cific clinical tasks independently after they have been trusted.Methods:Through documental analysis and semi-structured interviews,the item database of entrustable professional activities for psychiatric resident training physi-cians was established.Delphi consultation was conducted among 63 experts in the field of psychiatry from 7 national resident training bases and 3 medical colleges in China.Indicators were comprehensively screened and sorted out,and indicators at all levels and their weights were determined by the analytic hierarchy process.Results:A hierarchi-cal evaluation index system of entrustable professional activities for psychiatric resident training doctors was con-structed,including 4 first-level indicators,17 second-level indicators and 68 third-level indicators.The weights of the first-level,second-level and third-level indicators were determined.Conclusion:The evaluation index system of en-trustable professional activities is comprehensive and systematic,which is suitable for clinical work and convenient for practical application.It could provide quantitative standards for the assessment of psychiatric residents and pro-mote the improvement of training quality.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective To summarize the liver biopsy and clinical features of patients with liver injury of unknown origin,and to investigate the value of ultrasound-guided percutaneous liver biopsy in the diagnosis of liver injury of unknown origin.Methods A retrospective analysis was performed for the clinical data and ultrasound-guided percutaneous liver biopsy results of 94 patients with liver injury of unknown origin who were admitted to Zhongshan Hospital,Xiamen University,from January 2018 to February 2023.According to the proportion of the patients with different final diagnoses,the patients were divided into autoimmune liver disease(AILD)group,metabolic associated fatty liver disease(MAFLD)group,drug-induced liver injury(DILI)group,alcoholic liver disease(ALD)group,and unknown group.An analysis of variance was used for comparison of normally distributed continuous data between multiple groups,and the Bonferroni analysis or the Dunnett'T3 test was used for further comparison between two groups;the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups;the Fisher's exact test was used for comparison of categorical data between multiple groups.Results All 94 patients with liver injury of unknown origin underwent ultrasound-guided percutaneous liver biopsy after admission,among whom 90 patients(95.7%)had a confirmed diagnosis based on liver biopsy and clinical features.There were 43 patients(45.7%)with AILD,21(22.3%)with MAFLD,15(16.0%)with DILI,6(6.4%)with ALD,1(1.1%)with AILD and MAFLD,1(1.1%)with hemochromatosis,1(1.1%)with Budd-Chiari syndrome,1(1.1%)with congenital hepatic fibrosis,and 1(1.1%)with idiopathic portal hypertension,while 4 patients(4.3%)still had an unknown etiology after liver biopsy.There were significant differences between the patients with top five diagnoses in age(F=4.457,P<0.05),body mass index(BMI)(F=3.245,P<0.05),aspartate aminotransferase(AST)(H=11.128,P<0.05),gamma-glutamyl transpeptidase(GGT)(H=24.789,P<0.05),alkaline phosphatase(ALP)(H=26.013,P<0.05),IgG(H=19.099,P<0.05),IgM(H=21.263,P<0.05),AMA-M2 positive rate(P<0.05),and ANA positive rate(P<0.05).Compared with the MAFLD group,the AILD group had significantly higher age,AST,GGT,and ALP and a significantly lower BMI;compared with the MAFLD group and the DILI group,the AILD group had significant increases in IgG and IgM;the AILD group had significant increases in the positive rates of AMA-M2 and ANA compared with the other four groups.Conclusion AILD,MAFLD,and DILI are the most common causes in patients with liver injury of unknown origin.Ultrasound-guided percutaneous liver biopsy plays an important role in determining the cause of liver injury of unknown origin,but it is still needed to make a comprehensive analysis based on clinical history,different types of liver injury,laboratory markers,and imaging data.

Objective To investigate the impact of intrauterine infection combined with perinatal antibi-otic treatment on early neonatal gut microbiota.Methods Forty-six full term neonates delivered and hospital-ized in the Pediatrics Department of Women and Children's Hospital of Chongqing Medical University from January to June 2022 were selected as the study subjects.They were divided into the observation group (hav-ing,n=22) and the control group (not having,n=24) according to whether or not the mothers having chorio-amnionitis.The fecal samples were collected from the subjects on 0-2 d and 5-7 d after birth.The high-throughput sequencing technology was applied to conduct the bacterial 16S rRNA gene sequencing analysis in the fecal samples.The diversity,classification and relative abundance of gut floras were compared.Results Compared with the control group,the antibiotics use rate in prenatal and neonatal period in the observation group was higher,the antibiotic use duration in the neonatal period was longer,and the differences were statistically sig-nificant (P<0.05).The Shannon index on 5-7 d after birth in the two groups was increased compared with that on 0-2 d,moreover the observation group was lower than the control group,and the differences were statistically significant (P<0.05).The two groups of gut floras were mainly composed of Proteobacteria,Fir-micutes,Bacteroidetes,and Actinobacteria. Compared with the control group,the relative abundance of Pro-teobacteria on 5-7 d after birth in the observation group was higher,and the relative abundance of Actinobac-teria was lower,the differences were statistical significant (P<0.05). The two groups of gut floras were mainly composed of Bifidobacterium,Enterococcus,Streptococcus,Klebsiella,Bacteroidetes,and Escherichia/Shigella genera.Compared with the control group,the relative abundance of Bifidobacterium,Streptococcus and Bacteroides on 5-7 d after birth in the observation group was lower,the relative abundance of Klebsiella,and Escherichia/Shigella was higher,the differences were statistically significant (P<0.05).Conclusion In-trauterine infection and perinatal antibiotic treatment decrease the diversity of early neonatal gut flora,and the development of specific floras is delayed.

Purpose To explore the value of contrast-enhanced ultrasound(CEUS)in the differential diagnosis of gallbladder polypoid lesions(GPLs)(diameter≥10 mm).Materials and Methods A prospective enrollment of 229 patients with GPLs who underwent cholecystectomy in 17 hospitals from December 1 2021 to June 30 2024 was conducted to analyze the relationship between general data,conventional ultrasound,CEUS characteristics and the nature of GPLs.Multivariate Logistic regression was employed to identify independent risk factors for neoplastic polyps,the differential diagnostic value of different indicators was compared.Results Among 229 patients with GPLs,there were 108 cases of cholesterol polyps,102 cases of adenoma and 19 cases of gallbladder cancer.Age(Z=-4.476,P<0.001),polyp number(χ2=15.561,P<0.001),diameter(Z=-8.149,P<0.001),echogenicity(χ2=9.241,P=0.010),vascularity(χ2=23.107,P<0.001),enhancement intensity(χ2=47.610,P<0.001),enhancement pattern(χ2=6.468,P=0.011),vascular type(χ2=84.470,P<0.001),integrity of gallbladder wall(χ2=7.662,P=0.006)and stalk width(Z=-9.831,P<0.001)between cholesterol polyps and neoplastic polyps were statistically significant.Age,location,diameter,echogenicity,enhancement pattern,vascular type and stalk width between adenoma and gallbladder cancer were statistically significant(Z=-4.333,-3.902,-5.042,all P<0.05).Multivariate Logistic regression analysis showed that hyper-enhancement,branched vascular type and stalk width were independent risk factors for neoplastic polyps(OR=4.563,5.770,3.075,all P<0.001).The combination of independent risk factors was better than single factor and diameter in the differential diagnosis of cholesterol polyps and neoplastic polyps(all P<0.01).Conclusion CEUS can effectively identify the nature of GPLs and provide a valuable imaging reference for the selection of treatment methods.

Objective:To evaluate the clinical effect of high-intensity focused ultrasound(HIFU)and drug con-servative treatment on the treatment of type Ⅰ and type Ⅱ cesarean scar pregnancy(CSP).Methods:A retrospec-tive analysis was performed on 191 patients diagnosed with type Ⅰ and type Ⅱ CSP by ultrasonography and trea-ted in Mianyang Central Hospital from January 2018 to December 2021,and they were divided into drug group(n=67)and HIFU group(n=124)according to different treatment methods before curettage surgery.After receiv-ing conservative drug treatment or HIFU treatment,preformnegative pressure suction curettage under ultrasound monitoring to evaluate the effectiveness and safety of the two pretreatment methods.Results:There were no sig-nificant differences in age,number of cesarean sections,gestational age,the maximum diameter of the gestational sac,number of incision pregnancies,the β-hCG level before pretreatment,the heart tube pulse in the gestational sac,size of fetal bud,and fertility requirements between the medication group and HIFU group(P＞0.05).The proportion of type Ⅱ incision in HIFU group was higher than that in drug group(P＜Q.05).There were no signifi-cant differences between the two groups in intraoperative bleeding,treatment outcome effective rate after pretreat-ment,postoperative vaginal bleeding duration,postoperative uterine cavity residual,rate of reoperation and rate of repregnancy(P＞0.05).There were statistical differences between the two groups in the operation time of curet-tage surgery,whether the operation method was changed after pre-treatment,total hospital stay,β-hCG recovery time and hospitalization cost(P＜0.05).Following up to November 2022,there were 12 cases re-pregnancies in the drug group and 16 cases re-pregnancies in the HIFU group.Conclusions:For type Ⅰ and type Ⅱ CSP,HIFU pretreatment before negative pressure suction curettage under ultrasound monitoring is a safe and effective treat-ment,which improves the treatment effect and reduces the hospitalization time of patients.It may be an effective clinical therapy for type Ⅰ and type Ⅱ CSP treatment.

A total of 4 patients with renal cancer were admitted to our hospital from October 2006 to September 2015 in a familial renal cancer family. Among the 4 patients, 1 patient showed unilateral multiple clear cell carcinoma, 1 patient showed bilateral multiple clear cell carcinoma, and 2 patients showed bilateral multiple chromophobe cell carcinoma. No mutation of VHL or FLCN gene was found in all patients by genetic analysis.

Objective:To analyze the outcomes of extremely preterm infants (EPIs) after the implementation and quality improvement of an intervention program from the prenatal period to delivery room and the factors influencing the mortality of EPIs.Methods:This was a retrospective study involving 185 EPIs admitted to neonatal intensive care unit (NICU) of Chongqing Health Center for Women and Children from July 1, 2014, to June 30, 2021. The intervention program from the prenatal period to delivery room was implemented in our hospital in January 2018, according to which, EPIs who were admitted before this time were grouped as the historical group ( n=45) and those who were admitted after as the program group ( n=140). The survival rate and morbidity of the two groups were analyzed and compared using t test, Mann Whitney U test, and Chi-square test. The factors influencing the mortality of EPIs were analyzed by univariate screening and logistic regression. Results:(1) The median gestational age of these EPIs was 26 +6 weeks, ranging from 23 +3 to 27 +6 weeks, and the median birth weight was 950 g, ranging from 390 g to 1 290 g. (2) After the intervention, the proportion of patients in whom the neonatologists were involved in prenatal consultation, women who received a full course of antenatal corticosteroid and magnesium sulfate, and cesarean delivery as well as the neonatal temperature on admission to NICU all increased significantly [77.1% (108/140) vs 8.9% (4/45); 67.9% (95/140) vs 35.6% (16/45); 67.1% (94/140) vs 48.9% (22/45); 44.3% (62/140) vs 17.8% (8/45); 36.6 ℃ (36.3-36.9 ℃) vs 35.2 ℃ (35.0-35.3 ℃), respectively, χ2 or Z values were 66.41, 14.81, 4.85, 10.17 and－9.34, respectively, all P<0.05]. Both delayed cord clamping (DCC) and nasal continuous positive airway pressure (nCPAP) were included in the intervention program, with implementation rates from zero before to 67.9% (95/140) and 89.3%(125/140), respectively. Compared to the historical group, the proportion of infants with 1-minute Apgar score ≤3, endotracheal intubation in the delivery room or mechanical ventilation within 72 h after birth were decreased in the program group [7.1% (10/140) vs 17.8% (8/45), 37.1% (52/140) vs 73.3% (33/45), 38.6% (54/140) vs 57.8% (26/45), χ2 values were 4.39, 17.96 and 5.12, respectively. all P<0.05]. (3) After the intervention, the overall survival rate of EPIs and that among those with gestational age from 27 to 27 +6 weeks were significantly improved [72.9% (102/140) vs 53.3% (24/45), OR=2.349, P=0.015; 84.1% (53/63) vs 56.6% (13/23), OR=4.077, P=0.007]. Although the incidence of periventricular and intraventricular hemorrhage, late-onset sepsis, and retinopathy of prematurity showed a downward trend, the differences were not statistically significant (all P>0.05) (4) Multivariate logistic regression analysis showed that 1-minute Apgar score ≤3 ( OR=8.890, 95% CI:2.005-39.412), low 5-minute Apgar score ( OR=1.468, 95% CI:1.103-1.953), and higher rate of mechanical ventilation within 72 h ( OR=7.165, 95% CI:2.942-17.449) were independent risk factors for the mortality of EPIs; and using nCPAP in the delivery room ( OR=0.314, 95% CI:0.137-0.719) and birth weight ( OR=0.996, 95% CI:0.993-0.999) were protective factors. Conclusions:Early interventions for EPIs in the prenatal period or the delivery room, the quality improvement program, including intrapartum temperature management, DCC, and nCPAP, is likely to improve the survival rate and outcome of EPIs.

Objective:With the development of digital technology, network technology and mobile technology, new media aided-teaching has become a hot topic in medical teaching. However, the studies about the application of new media aided-teaching in training for professional postgraduates of neurosurgery are still less studied.Methods:In this study, 24 Batch 2015-2016 professional postgraduates of neurosurgery from Neurosurgery Department of Affiliated Hospital of Southwest Medical University were divided into the test group and control group, with 12 students in each group. From September 2016 to August 2018, students in the test group were taught with conventional teaching and various new media such as WeChat official accounts, professional video sharing websites and so on. The control group adopted conventional teaching methods. Students' theoretical knowledge, operation ability and clinical research ability were assessed between the two groups. SPSS 22.0 software was used for t test and descriptive statistics on the data.Results:The results of t test analysis showed that the scores of theoretical knowledge and general ability in test group were higher than those in control group, with significant differences ( P < 0.05). Meanwhile, the scores of teaching satisfaction, professional interest, teaching participation, knowledge mastery and scientific research ability in the test group were higher than those in the control group, with significant differences ( P<0.05). Conclusion:Conventional teaching combined with new media aided-teaching is a good new training model for professional postgraduates of neurosurgery, which has improved students' participation and motivation of study and contributed to the training of medical students' comprehensive abilities.

Objective: To explore the relationship among cognitive flexibility, depression and eating attitude of adolescents and the influencing factors of eating attitude. Methods: A total of 1 231 subjects were assessed using general information questionnaire, Kutcher Adolescent Depression Scale 11 item(KADS-11), Cognitive Flexibility Inventory(CFI), Eating Attitude Test 26(EAT-26). Data were analyzed by independent sample t-test, univariate linear regression, spearman correlation analysis and Logistic regression. Results: There were significant differences in EAT 26 among adolescents between genders and between those with or without depression(P<0.01). Statistically significant differences were observed in CFI, flexible control and KADS 11 among adolescents with or without eating disorders(P<0.01). The scores of EAT 26 was negatively correlated with CFI (r=-0.19, P<0.01) and flexible control(r=-0.23, P<0.01). And there was a significant positive correlation between EAT 26 and KADS 11(r=0.23, P<0.01). Female(OR=2.40, 95%CI=1.87-3.23), depression (OR=1.76, 95%CI=1.35-2.29) and poor flexible control (OR=1.94, 95%CI=1.48-2.54) were risk factors for eating disorders. Conclusion Female, individuals with depressive symptoms or with poor flexible control ability are more likely to have eating disorders which need more attention.
