Objective:To enhance the understanding of clinical doctors on the concurrence of Sj?gren′s syndrome (SS) and myasthenia gravis (MG), provide reference forclinical diagnosis and treatment.Methods:The medical record of SS、MG patient Taian Central hospital in october 2021 was reviewed and a retrospective analysis was conducted. Based on the key words, the main databases domestic and abroad from Jan 1973 to April 2024. The cases reported in the literature were searched out and merged with our case and analyzed by SPSS 27.0. The measurement data of normal distribution were expressed by mean standard deviation ± s, and the measurement data of abnormal distribution were expressed by M( Q1, Q3). Counting data were expressed as examples and percentages (%) . Results:Twenty-one patients with SS complicated with MG were reviewed. Among them, 19(90.5%) patients were female. The average age was (47.6 ± 3.1) years, and the median time from onset to diagnosis was 24 (11, 78) months. There were 11 patients (52.4%) with myasthenia gravis as the initial presentation. The main clinical manifestations of patients with myasthenia muscle fatigue (80.9%, 17/21), gravis include fatigue ptosis (71.4%, 15/21), diplopia, blurred vision (57.1%, 12/21), dysphagia (33.3%, 7/21), joint pain (33.3%, 7/21), odysarthria, and unclear speech (23.8%, 5/21), hair loss (14.3%, 3/21), and swelling of the excocrine glands(9.5%, 2/21). Eighteen patients (85.7%, 18/21) showed positive anti acetylcholine receptor antibodies. Sixteen patients (76.2%) were positive for ANA, and 14 patients (66.8%) were positive for anti SSA or (and) anti SSB antibodies. Four patients (19.0%) also had other autoimmune diseases (Hashimoto′s thyroiditis, rheumatoid arthritis, optic neuritis). In terms of treatment, cholinesterase inhibitors were the most common treatment measure, applied to 18 patients (85.7%), followed by glucocorticoid therapy, and applied to 14 patients (66.8%). In addition, 7 patients (33.3%) received immunosuppressive agents therapy, 5 patients (23.8%) underwent thymectomy, 2 patients (9.5%) received intravenous human immunoglobulin injection, and 1 patient (4.8%) underwent plasma exchange. All patients showed improvement after treatment.Conclusion:SS and MG are both autoimmune diseases, and their coexistence is rare. Clinicans should be aware of this rare association. Early diagnosis is crucial for the treatment and prognosis of patients,and requiresa comprehensive assessment of clinical symptoms, laboratory tests, and auto-antibody test results.

Objective To investigate the mechanism of action and potential biomarkers of Jiangzhi Qingshen capsules in the treatment of dyslipidaemia based on clinical lipid metabolomics.Methods 30 patients with dyslipidaemia from Zhengzhou Hospital of Chinese Medicine were collected as the test group,and their lipid levels before and after taking Jiang Zhi Qing Shen capsule for 12 weeks were compared.Another 30 healthy patients were enrolled in the physical examination department of Zhengzhou Hospital of Chinese Medicine,and metabolomics investigation was carried out on plasma samples of the test group before and after the treatment as well as those of the healthy patients by LC-MS/MS technology.The differences between the groups were compared by multivariate statistical analysis,and the potential biomarkers were identified by HMDB and lipidblast databases,so as to clarify the possible pathways and targets for the treatment of mild dyslipidaemia by Jiangzhi Qingshen capsules.Results Jiangzhi Qingshen capsules could improve patients' blood lipid level,BMI and abdominal circumference significantly(P<0.05).And metabolomics results showed that 29 lipid metabolites in the plasma of the treated patients were dialled back,which involved cholesterol metabolism,fat digestion and absorption,glycerol-phospholipid metabolism and other biological processes.Conclusion The efficacy of Jiangzhi Qingshen capsules in treating dyslipidaemia was confirmed,and its mechanism of action might be related to the regulation of lipid metabolism.Metabolites such as acylcarnitine(Acar),phosphatidylethanolamine(PE)and phosphatidylcholine(PC)were expected to be used as the biomarkers of dyslipidaemia,so as to provide objective scientific basis for the lipid-lowering capsule,and to facilitate the promotion of its application.

Objective To explore the effect of transcutaneous electrical acupoint stimulation bracelet at Neiguan acupoint on the postoperative nausea and vomiting after thyroidectomy under general an-esthesia.Methods Seventy-two female patients underwent thyroidectomy,aged 18-50 years,ASA physical status Ⅰ or Ⅱ,were enrolled.The patients were assigned 1 ∶ 1 to two groups by permuted block randomization:the electrical stimulation group and the control group,36 patients in each group.Before an-esthesia induction,patients in both groups wore domestic transcutaneous electrical acupoint stimulation bracelets,and the electrodes were aimed at Neiguan acupoint.The electrical stimulation group started to stimulate Neiguan acupoint,and adjusted the proper intensity to make the patient feel tingling in the related area of the hand.When the bracelet was fixed firmly,turned it off.At the end of the operation,the bracelet was turned on with the stimulation intensity set before induction for 24 hours.Patients in the control group also wore the bracelet for 24 hours,but it was never turned on.The number of cases of postoperative nausea and vomiting(PONV)and the number of remedial cases of antiemetic drugs were recorded.Results Compared with the control group,the incidence of PONV and postoperative vomiting in the electrical stimula-tion group were significantly reduced within 24 hours after surgery(P＜0.05),and the differences were mainly in 1-6 hours after surgery(P＜0.05).There was no significant difference in the rate of remedial ca-ses of antiemetic drugs between the two groups at different time periods.Conclusion Transcutaneous electri-cal stimulation bracelet at Neiguan acupoint can effectively reduce the incidence of PONV within 24 hours after thyroidectomy.

Objective To explore the patterns of functional gait asymmetry during the support phase and the differentiation of bilateral foot functions,to gain insights into the human movement compensa-tion mechanisms and stability control characteristics,so as to provide theoretical references for the pre-vention and rehabilitation treatment of unilateral foot and ankle injuries.Methods Twelve young females with normal feet were recruited,and the time percentage of each phase of the support period,the change of longitudinal arch angle,the vertical ground reaction force and the center of plantar pressure trajectory of the dominant and non-dominant feet were collected by using a three-dimensional motion capture and a high-frequency plantar pressure testing system when the subjects walked at the optimum speed with the incremental loading of weights[0%body weight(BW),10%BW and 20%BW].The ef-fects of laterality(dominant foot,non-dominant foot)and load(0%BW,10%BW,20%BW)on arch changes and gait parameters,and the interactions between them,were analyzed using a two-way re-peated-measures ANOVA.Results The factors of laterality and load interacted significantly on arch changes,but not on gait parameters.(2)Compared with 0%BW,the time percentage of the buffering phase of the nondominant feet with the load of 20%BW increased(P<0.05),while that of the domi-nant ones decreased(P<0.05),with an increase in the buffering load of both feet with the load of 20%BW(P<0.05)and the buffering force excursion of both feet with the load of 10%BW(P<0.05).More-over,changes in longitudinal arch angle increased(P<0.05)with the load of 10%and 20%BW,the pedal extension load rate increased(P<0.05)with the above BW load in the non-dominant feet,and the horizontal slope of pedal extension decreased(P<0.05)with 20%BW load in the dominant feet.Compared with 10%BW,when the feed was loaded 20%BW,the time percentage in the buffering phase and the buffering force offset of the dominant feet decreased(P<0.05),while the buffering load of both feet increased(P<0.05).(3)Compared with the non-dominant feet,for the dominant feet,the buffering load rate at the load of 10%and 20%BW and changes in the longitudinal arch angle at the load of 20%BW decreased(P<0.05),while the horizontal slope of the pedal extension without load in-creased(P<0.05).Conclusion Walking with load induces function differentiation in bilateral feet.The dominant foot has more efficient horizontal extension without load and better buffering function in the vertical direction with loads,while the non-dominant feet perform a more adequate weight-bearing and extension function vertically with larger load.It is suggested that unilateral injury feet should not be given too much load,and it is inappropriate to select a single foot to represent and evaluate the func-tion and injury risk of the double feet in loaded walking.

Objective:To analyze the supervision mode and problems of intensive countywide medical communities and explore the methods and strategies to improve their supervision system.Methods:From March 2022 to May 2022, a stratified random sampling method was used and the intensive countywide medical communities in the province were selected for field study. In-depth interviews were made with the staff of the healthcare administration departments and health insurance agencies affiliated with intensive countywide medical communities, directors of general hospitals, directors of township hospitals, and heads of functional departments. These interviews mainly covered the principal entities of countywide medical community supervision, supervision measures and contents, supervision effects, supervision weaknesses, and how to improve internal and external supervision mechanisms. The interviews results were analyzed using thematic framework analysis and the data were subject to a descriptive analysis.Results:23 persons of five intensive countywide medical communities were selected for key person interview. The finalized framework of regulatory elements of intensive countywide medical communities consists of such five general themes as regulatory subjects, regulatory content, regulatory measures, regulatory effectiveness and existing problems, comprising 14 level-1 indicators and 52 level-2 indicators. The main regulatory bodies were mainly government departments (15 times), the regulatory content was focused on medical resources (10 times), the regulatory measures cover specific regulations (4 times), specific activities (4 times) and assessment and evaluation (4 times). And the regulatory effectiveness demonstrated a currently strong regulation strength of medical communities (5 times), and the existing problems were insufficient government supervision (12 times), difficulties encountered by social forces in their supervision (11 times) and internal governance (5 times).Conclusions:The supervision system of intensive countywide medical communities should be optimized by improving the governmental supervision mechanism, inviting supervision of social forces and building an effective internal governance.

Objective To analyze the epidemiological characteristics of norovirus infectious diarrhea in the active monitoring of foodborne diseases in Jiangsu Province from 2015 to 2020, so as to provide reference for the prevention and control of foodborne diseases caused by norovirus. Methods Norovirus positive diarrhea cases were collected from sentinel hospitals in 13 districts and cities of Jiangsu Province, and their epidemiological and clinical characteristics were analyzed. Results Atotal of 3 620 norovirus positive cases were detected and isolated from 61 489 samples. The main serotype was GII (71.97%), the onset season was winter and spring, and the onset age was 1-3 years old and 14-34 years old. There was no significant difference in norovirus positive rate between different sexes, and the main symptom was diarrhea (incidence rate was 92.10%), Meat and meat products (20.20%) were the main types of suspected exposed foods. Conclusion Norovirus infection has obvious seasonal characteristics, and the population is generally susceptible. It is high in children and young people, and meat food was the main suspicious exposure food. We should continue to improve the ability of active monitoring, identification, early warning and control of foodborne diseases, so as to reduce the occurrence of foodborne diseases.

OBJECTIVE To establish the quality evaluation method of Polyporus formula granules, and to comprehensive evaluate the quality uniformity and stability of products from different manufacturers. METHODS The fingerprint of Polyporus formula granules was determined by HPLC. Shim-pack GIST C18-AQ(4.6 mm×150 mm, 3 μm) was used, mobile phase was acetonitrile-water with gradient elution, volume flow rate was 1.0 mL·min-1, detection wavelength was 350 nm (0-3 min) and 250 nm(3-35 min), column temperature was 30℃. HPLC fingerprints of Polyporus formula granules from different manufacturers were established, common peaks were identified, similarities were evaluated and cluster analysis were performed. HPLC was used to determine the contents of 4 active ingredients, and the quality of 16 batches of samples was analyzed and evaluated. RESULTS The established HPLC fingerprint of Polyporus formula granules defined 14 common peaks and identified 6 common components. They were peak 2(uridine), peak 4(guanosine), peak 6(adenosine), peak 12(polyporusteron B), peak 13(polyporusteron A), peak 14(polyporusteron C). The similarity of 16 batches of samples were 0.609-0.982, and could be clustered into 2 categories by cluster analysis. Guanosine, adenosine, polyporusteron B and polyporusteron A all showed good linear relationships(r ≥ 0.999 7), RSDs of instrument precision, stability and reproducibility tests were <3%. The average recoveries were 98.22%, 99.32%, 99.56%, 99.15%, RSD<3%(n=6). The contents of guanosine, adenosine, polyporusteron B, polyporusteron A in 16 batches of samples were 6.326-28.006, 13.392-44.058, 10.324-30.335, 9.270-26.964 μg·g-1.CONCLUSION There is considerable quality difference among different manufacturers. The established fingerprint combine with the compound determination can comprehensively and accurately evaluate the internal quality of Polyporus formula granules, and provide a basis for the overall improvement of the quality.

Objective To analyze the correlation between intestinal flora changes and neonatal necrotizing enterocolitis (NEC)through 16S rRNA metagenomic sequencing and bacterial culture. Methods From September 2018 to March 2019, 10 NEC cases and 6 controls were randomly selected in the neonatal ICU ward of Nanjing maternal and child health care hospital to analyze the 16S rRNA metagenomic diversity of the for intestinal flora. The fecal samples and corresponding environmental samples were corrected from 51 cases of NEC children and their case controls to isolate and culture Clostridium. Results The dispersion of samples within the case group was smaller than that of the control group, and the sample diversity was higher than that of the control group. In the isolation and culture of Clostridium, the overall detection rate of Clostridium in the case group was 43.14% (22/51), and the detection rate of Clostridium butyricum was the highest (19.61%, 10/51). There was a statistical difference between the two groups (χ²=5.85, P=0.015 58). All Clostridium strains did not carry the A, B and E type neurotoxin genes. Conclusion: Increased intestinal flora diversity, intestinal flora abundance and changes in the abundance of Clostridium may be closely related to the intestinal environment of children with NEC; Clostridium, especially Clostridium butyricum, may be related to the occurrence of NEC.
