ObjectiveTo improve the quality and service performance of community visual health services in Shanghai, and to establish a set of reasonable and effective evaluation index system for community visual health services. MethodsCentered on the national and Shanghai-based visual health policies and based on the current status and development trends of community visual health service program in Shanghai, the candidate indicators were formed through literature review and expert interviews, firstly. The framework of an evaluation index system was formulated through qualitative research successively, which was further revised and perfected using the Delphi method. Coefficient weights were calculated using the analytic hierarchy process (AHP), culminating in the establishment of the community visual health evaluation index system, lastly. ResultsA total of 22 visual health experts from district-level center for disease control, hospital ophthalmology and leaders in charging of visual health service in community health centers participated in the Delphi questionnaire survey, with a questionnaire recovery rate of 100% and an expert authority coefficient of 0.86, indicating high credibility. After a round of correspondence to experts’ importance ratings and discussions, a comprehensive evaluation index system comprising 3 primary indicators, 12 secondary indicators, and 47 tertiary indicators, along with 5 additional indicators, was finalized. ConclusionAn index system tailored to effective evaluation for community visual health initiatives was drawn up in this study, which can promote the capacity building in community eye health services, facilitating the high-quality development of visual health courses, and enhancing residents’ eye health.

Objective:To construct talent training objectives and courses for undergraduate education of tropical medicine.Methods:Two rounds of questionnaire consultation were conducted among 15 experts by Delphi method. SPSS 26.0 software was used for statistical analysis, and the recovery rate, expert authority coefficient, mean of importance score, full score ratio, coefficient of variation and Kendall coordination coefficient were calculated respectively. Kendall's rank correlation test was used to analyze the degree of expert coordination, and the "boundary value method" was used to screen the indicators.Results:The effective recovery rates of the two rounds of consultation were all 100.00% and the expert authority coefficient was 0.815. The coordination coefficient was 0.25, 0.32, and 0.27, 0.36 respectively, and the significance test showed P<0.001. Finally, 11 talent training objectives and 7 courses for undergraduate education of tropical medicine were formed. Conclusions:The talent training objectives and courses for undergraduate education of tropical medicine are reasonable and reliable, which can provide theoretical support for tropical medicine talent training and have certain guiding value.

This article aimed to summarise the clinical experience of Professor XIONG Jibai in treating henoch-schonlein purpura （HSP） from the perspective of "simultaneous treatment of wind and blood". HSP was devided into acute phase and transitional phase in clinic. It was considered that the wind pathogen exists throughout the disease course， and the treatment is guided by the "four methods of treating blood" in TANG Rongchuan's Treatise on Blood Syndromes - Blood Vomiting （《血证论·吐血》）， which are stanching bleeding， expelling stasis， tranquilising blood， and tonifying blood. In the acute phase， wind-heat damaging collateral symdrome and blood-heat frenetic flow syndrome are common， which could be treated by the method of cooling blood to dispel wind， and eliminating stasis to stop bleeding， with self-prescribed modified Ziping Xiaofeng Powder （紫萍消风散）； in the transitional phase， syndrome of effulgent fire due to yin deficiency and syndrome of qi deficiency failing to control are common， which could be treated by the method of tranquilising blood and tonifying deficiency， with modified Zhibai Dihuang Decoction （知柏地黄汤） and Guipi Decoction （归脾汤）. At the same time， it is believed that wind-related medicinal has the function of eliminating stasis， stanching bleeding， and cooling blood， and the wind-related medicinal should be used throughout the treatment.

Background Currently,there has been a gradual increase in the incidence of mental diseases,becoming a problem that has attracted great concern of the general public.Zhuhai is a core city of the Guangdong-Hong Kong-Macao Greater Bay Area,and the local government have attached great importance to the mental health of residents.The systematic study on the mental health has focused largely on pregnant women and medical workers,yet few are on the adult residents.Objective To investigate the prevalence and its influencing factors of anxiety and depression among adult residents in Zhuhai,so as to provide references for formulating targeted psychological intervention strategies.Methods From September 1 to December 1,2021,a cohort of 5 600 permanent residents aged 18 years and above in Zhuhai were selected through multistage sampling.All participants were subjected to complete Patients' Health Questionnaire Depression Scale-9 item(PHQ-9),Generalized Anxiety Disorder Scale-7 item(GAD-7)and National Mental Health Literacy Questionnaire based on Wenjuanxing software.Then Logistic regression was employed to identify the factors associated with anxiety and depression among the residents.Results Among the 5 600 residents,depressive symptoms were detected in 842(15.04％)residents and anxiety symptoms in 579(10.34％)residents.Logistic regression analysis yielded that female gender(OR=1.488),living in Doumen district(OR=1.942),junior college/undergraduate level(OR=3.602),postgraduate and above(OR=5.904),irregular meal pattern(OR=3.320),comorbid chronic diseases(OR=3.244),disqualification of self-assessment(OR=3.414)and disqualification of mental health skill(OR=2.131)were risk factors for depression symptoms,whereas age≥25 years old(of all age groups OR<1),monthly per capita income>20 000 yuan(OR=0.438)and exercising≥3 times a week(OR=0.431)were protective factors for depression symptoms.Age of 25～34 years old(OR=2.051),living in Jinwan district(OR=1.729)or Doumen district(OR=1.901),junior college/undergraduate level(OR=2.955),postgraduate and above(OR=6.662),irregular meal pattern(OR=2.741),comorbid chronic diseases(OR=3.535),disqualification of self-assessment(OR=3.325)and disqualification of mental health skill(OR=1.838)were risk factors for anxiety symptoms,while monthly per capita income of 6 001～9 000 yuan(OR=0.665)and exercising≥3 times a week(OR=0.572)were protective factors for anxiety symptoms.Conclusion The mental health status of adult residents in Zhuhai is affected by various factors,including gender,age,region of residence,education level,meal pattern,exercise frequency and chronic diseases.

Objective:To understand molecular characteristics and antibiotic resistance of Clostridioides ( C.) difficile isolated from children in China, and provide data support the development of disease risk assessment and burden studies. Methods:A total of 155 strains of C. difficile isolated from children aged <12 years in 14 provinces (autonomous regions, municipalities) in China from 2010 to 2023 were used for the analyses on molecular characteristics and antibiotic resistance of C. difficile by PCR and drug susceptibility test. Results:A total of 26 sequence types (STs) and 18 ribotypes (RTs) were identified in the 155 C. difficile isolates, in which ST3 (20.65%), ST54 (16.13%), ST35 (12.90%), and RT012/ICDC007 (14.84%), RT001/ICDC001 (11.61%), RT046/ICDC018 (8.39%) were the most common. One highly virulent strain with RT078 and 27 non-toxin-producing strains were also found; the predominant toxin gene was tcdA+ tcdB+ cdt-. All the strains were sensitive to metronidazole and vancomycin, and there were 29 multidrug-resistant strains, in which 1 strain was resistant to all the seven antibiotics except for vancomycin and metronidazole. Conclusions:Molecular characteristics and antibiotic resistance of C. difficile in children were similar to those in whole population in China, but there were regional distribution differences. It is necessary to strengthen the routine drug-resistance surveillance for C. difficile infection in children in China.

Objective:To investigate the clinical characteristics and treatment of patients with perianal necrotizing fasciitis.Methods:This study was a retrospective cohort study. Twenty patients with perianal necrotizing fasciitis who met the inclusion criteria were admitted to the Department of Burn and Plastic Surgery of the First Affiliated Hospital of Guangxi Medical University (hereinafter referred to as our department) from August 2013 to September 2023, including 19 males and 1 female, aged 24-74 (56±11) years. Based on the spreading route of perianal infection to the lower abdomen, the patients were divided into perianal-inguinal-lower abdominal wall group (12 cases) and perianal-pelvic cavity-retroperitoneal group (8 cases). The following clinical data were compared between the two groups of patients: general data, including gender, age, combined underlying diseases, blood glucose level and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score when admitted to our department, and laboratory risk indicator for necrotizing fasciitis (LRINEC) score when admitted to our department and at 14 d after admitted to our department; infection indicators when admitted to our department, including C-reactive protein level, white blood cell count, lymphocyte count, procalcitonin level, and lactic acid level; clinical outcome-related indicators, including time from onset to definite infection range, number of surgery, treatment in intensive care unit (ICU), length of hospital stay, treatment outcome, and recurrence of necrotizing fasciitis during follow-up; detection of pathogen and bacterial drug resistance in wound necrotic tissue specimen when admitted to our department.Results:Compared with those in perianal-inguinal-lower abdominal wall group, the APACHE Ⅱ score and lactic acid level when admitted to our department and LRINEC score at 14 d after admitted to our department (with t values of -5.98, -5.01, and -2.86, respectively, P<0.05) and ICU treatment ratio ( P<0.05) were significantly increased, the time from onset to definite infection range was significantly prolonged ( Z=-3.75, P<0.05), and the number of surgery was significantly increased ( Z=2.80, P<0.05) in patients in perianal-pelvic cavity-retroperitoneal group. There were no statistically significant differences in other data between the two groups of patients ( P>0.05). Eighteen patients were cured, and no recurrence of perianal necrotizing fasciitis was observed during follow-up of 6 months in 18 cured patients. The main bacteria were Escherichia coliand Klebsiella pneumoniae, and the fungui were Aspergillus and Candida albicans detected in wound necrotic tissue specimens in two groups of patients when admitted to our department. The ratio of multiple drug resistance of bacteria in wound necrotic tissue specimens in perianal-pelvic cavity-retroperitoneal group of patients was significantly higher than that in perianal-inguinal-lower abdominal wall group ( P<0.05). Conclusions:Perianal necrotizing fasciitis can spread to the lower abdomen through two routes: the perianal-inguinal-lower abdominal wall route and the perianal-pelvic cavity-retroperitoneal route. The latter is more insidious in disease progression and more challenging in treatment. Establishing a mechanism of multi-disciplinary team diagnosis and treatment can achieve the goal of early diagnosis and precise treatment of perianal necrotizing fasciitis.

Guillain-Barre syndrome rarely develops after allogeneic hematopoietic stem cell transplantation (allo-HSCT), and only a few reports exist in China. Guillain-Barre syndrome is an acute and life-threatening condition that requires early diagnosis and treatment. A patient with acute myeloid leukemia underwent allogeneic HSCT for >5 months and gradually developed limb muscle weakness and limited eye movement after coexisting with delayed acute intestinal graft-versus-host disease. After the examination of cerebrospinal fluid and electromyography, the diagnosis of Guillain–Barre syndrome was confirmed. After a high-dose intravenous immunoglobulin (IVIg) treatment, muscle strength gradually recovered, and the prognosis was good.

The onset of myasthenia gravis (MG) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) seriously threatens the survival of patients, since it is acute, and is prone to rapid progression. Two patients with acute myeloid leukemia (AML), who had undergone allo-HSCT developed shortness of breath, and gradually developed cervical weakness and dyspnea. The acetylcholine receptor (AChR) antibody and neostigmine test enabled the diagnosis of MG. The condition of the patients improved after treatment with pyridostigmine bromide, glucocorticoids and rituximab.

Objective:To evaluate the application value of transabdominal wall suspended laparoscopic appendectomy (LA) in patients with acute suppurative appendicitis or concurrent periappendiceal abscess.Methods:The clinical data of 107 patients with acute suppurative appendicitis or concurrent periappendiceal abscess in Hexi University, Zhangye People′s Hospital from September 2019 to December 2022 were retrospectively analyzed. Among them, 53 patients underwent open appendectomy (OA) (OA group), and 54 patients underwent transabdominal wall suspended LA (LA group). The operation time, postoperative pain score, postoperative hospitalization time, recovery time of gastrointestinal function, postoperative complications and hospital cost were compared between two groups.Results:In the LA group, 2 cases were transferred to OA due to heavy abdominal adhesion and unclear anatomy, and 3 cases could not undergo transabdominal wall suspended LA due to perforation of the root of the appendix or gangrene of the appendix. There was no statistical difference in operation time between two groups ( P>0.05); the postoperative hospitalization time, recovery time of gastrointestinal function, postoperative pain score and total incidence of postoperative complications in LA group were significantly lower than those in OA group: (4.92 ± 1.70) d vs. (7.51 ± 3.96) d, (20.64 ± 7.37) h vs. (35.32 ± 10.13) h, (5.62 ± 1.12) scores vs. (6.83 ± 0.93) scores and 5.56% (3/54) vs. 24.53% (13/53), the hospital cost was significantly higher than that in OA group: (8 325.47 ± 856.22) yuan vs. (6 458.64 ± 2 085.93) yuan, and there were statistical differences ( P<0.05). Conclusions:Transabdominal wall suspended LA has the advantages of wide indications, easy operation, minimal trauma, fast recovery, and fewer complications, but with relatively high hospitalization cost.

Objective:To evaluate the effect of applying high-fidelity simulation model in the teaching of lower urinary tract injury.Methods:A total of 50 junior medical students majoring in clinical medicine were enrolled. They were randomly assigned to the control group or the experimental group. The students in the control group were taught using the traditional method involving PPT presentation and videos on lower urinary tract anatomy, surgical basis of lower urinary tract injury, and operative methods for lower urinary tract injury. The students in the experimental group were taught using the simulation model for observation and related operation. After four class hours (40 minutes/class hour) of teaching, the students in the two groups were subjected to theoretical assessment and questionnaire survey. The differences between the two groups were compared and analyzed using the t and χ 2 tests in SPSS 26.0. Results:The total scores of theoretical assessment were (36.80±4.00) and (33.12±3.62) in the experimental group and the control group, respectively, and the difference was significant ( P<0.05). The results of the questionnaire showed that the self-evaluation of the experimental group was better than that of the control group in the mastery of theoretical knowledge, clinical operation, early treatment, operation process, and key steps, and the differences were statistically significant ( P<0.05). Conclusions:Compared with the traditional teaching method, the high-fidelity simulation model improves the efficiency of learning anatomy knowledge and operation process, and promotes the mastery of important and difficult knowledge in lower urinary tract injury. This method merits popularization.
