OBJECTIVE: To investigate the association between long-term glycemic control and cerebral infarction risk in patients with diabetes through a large-scale cohort study. METHODS: This prospective, community-based cohort study included 12,054 patients with diabetes. From 2006 to 2012, 38,272 fasting blood glucose (FBG) measurements were obtained from these participants. FBG trajectory patterns were generated using latent mixture modelling. Cox proportional hazards models were applied to assess the subsequent risk of cerebral infarction associated with different FBG trajectory patterns. RESULTS: At baseline, the mean age of the participants was 55.2 years. Four distinct FBG trajectories were identified based on FBG concentrations and their changes over the 6-year follow-up period. After a median follow-up of 6.9 years, 786 cerebral infarction events were recorded. Different trajectory patterns were associated with significantly varied outcome risks (Log-Rank P < 0.001). Compared with the low-stability group, Hazard Ratio ( HR) adjusted for potential confounders were 1.37 for the moderate-increasing group, 1.23 for the elevated-decreasing group, and 2.08 for the elevated-stable group. CONCLUSION Sustained high FBG levels were found to play a critical role in the development of ischemic stroke among patients with diabetes. Controlling FBG levels may reduce the risk of cerebral infarction.

This study was aimed at understanding the genomic characteristics of the Vibrio cholerae O1 group isolated from humans in Fujian Province,to provide essential data for the molecular epidemiological study of cholera.From 2008 to 2022,16 strains of the V.cholerae O1 group from patients and carriers were collected,and antibiotic sensitivity was determined accord-ing to the minimum inhibitory concentration(MIC).The whole genome sequences obtained through second generation sequen-cing were analyzed in open source software,including snippy,Roary,and Prokka,as well as online analysis websites,inclu-ding NCBI and BacWGSTdb,for core-genome multilocus sequence typing(cgMLST),core-genome single nucleotide polymor-phism analysis(cgSNP),virulence gene analysis,drug resistance gene prediction,and pan-genomic diversity analysis.The whole genome sequences of V.cholerae were divided into five sequence types(STs),among which the newly discovered ST182 and ST1480 were the evolutionary branches of the current dominant clonal group ST75 in China,and were highly related to two strains isolated from Taiwan in 2010 and 2013,respectively.Both toxigenic strains and non-toxigenic strains carried a variety of virulence factors and showed gene variation to varying degrees.Thirteen drug resistance genes in seven categories were predicted,among which the distribution of colistin and tetracycline resistance genes was consistent with the drug resistance phenotype.Pan-ge-nomic analysis indicated that V.cholerae had an open pan-genome,and Roary cluster analysis showed higher resolution than cgMLST.In summary,V.cholerae O1 group isolates from humans in Fujian Province have polymorphisms in genome structure and function,and the newly discovered ST1480 clone group has epidemic potential.Therefore,the monitoring of such strains must be strengthened.

Objective:To evaluate the effect of automated flexible endoscope channel brushing system (AFECBS) on endoscope reprocessing.Methods:A prospective randomized controlled study was conducted. The used endoscopes were divided into automatic group and manual group by random number table method, 200 in each group. In the automatic group, the AFECBS was used to scrub each tube 3 times during endoscope cleaning; and in the manual group, scrubbing and disinfection personnel routinely brushed each pipeline for 3 times. The primary end point was the qualified rate of endoscopic cleaning quality in the two groups, and the secondary end point was the time spent by the scrubbing and disinfection personnel on the two groups.Results:The qualified rate of overall cleaning in the automatic group was 90.0% (180/200), and in the manual group was 81.0% (162/200). The qualified rate of the automatic group was higher than that of the manual group ( χ2=6.534, P=0.011). The qualified rate of gastroscope cleaning in the automatic group was higher than that in the manual group [92.0% (127/138) VS 81.6% (120/147), χ2=6.658, P=0.010]. There was no significant difference in the qualified rate of colonoscope cleaning between the automatic group and the manual group [85.5% (53/62) VS 79.2% (42/53), χ2=0.774, P=0.379]. When the cleaning personnel scoured 5 endoscopes in each of the two groups, the time of the automatic group (5.17±0.42 min) was shorter than that of the manual group (9.60±0.53 min) ( t=92.644, P<0.001). Conclusion:Compared with manual scrubbing, AFECBS can improve the qualified rate of endoscope cleaning and the work efficiency of scrubbing and disinfection personnel, which is worthy of clinical application.

Non-alcoholic fatty liver disease (NAFLD) is considered to be a manifestation of metabolic syndrome and has become one of the chronic diseases that endanger health around the world. There is still a lack of effective therapeutic drugs in clinical practice. Farnesoid X receptor (FXR) has been a popular target for NAFLD research in recent years. Fexaramine (Fex) is a potent and selective agonist of FXR, and its mechanism of action to improve NAFLD is unclear. Therefore, in this study, a mouse model of NAFLD was constructed using a high-fat, high-cholesterol diet and treated with Fex orally for 6 weeks. We evaluated the ameliorative effect of Fex on disorders of glucolipid metabolism in NAFLD mice, and preliminarily explored its potential mechanism of action. The animal experiments were approved by the Animal Ethics Committee of Shanghai University of Traditional Chinese Medicine (approval number: PZSHUTCM210913011). In this study, it was found that 100 mg·kg^-1 Fex significantly inhibited body weight gain, alleviated insulin resistance, improved liver injury and lipid accumulation in NAFLD mice. The effect of Fex on the expression of hepatic intestinal FXR and its target genes in NAFLD mice was further examined. Analysis of serum and hepatic bile acid profiles and expression related to hepatic lipid metabolism. It was found that Fex could stimulate intestinal FXR, promote fibroblast growth factor 15 (FGF15) secretion, inhibit the expression of cytochrome P450 family 7 subfamily A member 1 (CYP7A1), the rate-limiting enzyme of bile acid synthesis in liver, regulate bile acid synthesis by negative feedback, and improve the disorder of bile acid metabolism. At the same time, Fex reduces liver lipid synthesis and absorption, increases fatty acid oxidation, thus improving liver lipid metabolism. This study shows that Fex can improve NAFLD by activating intestinal FXR-FGF15 signal pathway and regulating liver lipid metabolism.

Objective: To explore the epidemiological characteristic of a COVID-19 outbreak caused by 2019-nCoV Omicron variant BF.7 and other provinces imported in Shenzhen and analyze transmission chains and characteristics. Methods: Field epidemiological survey was conducted to identify the transmission chain, analyze the generation relationship among the cases. The 2019-nCoV nucleic acid positive samples were used for gene sequencing. Results: From 8 to 23 October, 2022, a total of 196 cases of COVID-19 were reported in Shenzhen, all the cases had epidemiological links. In the cases, 100 were men and 96 were women, with a median of age, M (Q₁, Q₃) was 33(25, 46) years. The outbreak was caused by traverlers initial cases infected with 2019-nCoV who returned to Shenzhen after traveling outside of Guangdong Province.There were four transmission chains, including the transmission in place of residence and neighbourhood, affecting 8 persons, transmission in social activity in the evening on 7 October, affecting 65 persons, transmission in work place on 8 October, affecting 48 persons, and transmission in a building near the work place, affecting 74 persons. The median of the incubation period of the infection, M (Q₁, Q₃) was 1.44 (1.11, 2.17) days. The incubation period of indoor exposure less than that of the outdoor exposure, M (Q₁, Q₃) was 1.38 (1.06, 1.84) and 1.95 (1.22, 2.99) days, respcetively (Wald χ²=10.27, P=0.001). With the increase of case generation, the number and probability of gene mutation increased. In the same transmission chain, the proportion of having 1-3 mutation sites was high in the cases in the first generation. Conclusions: The transmission chains were clear in this epidemic. The incubation period of Omicron variant BF.7 infection was shorter, the transmission speed was faster, and the gene mutation rate was higher. It is necessary to conduct prompt response and strict disease control when epidemic occurs.

Arrhythmia, a common and frequently occurring cardiovascular disease, causes a heavy burden on the public health of China. Approximately 20 million patients are suffering from this disease in China and treated by pharmacological and surgical therapies. However, antiarrhythmic drugs can cause arrhythmia and surgical treatment has the risks of failure and recurrence. Therefore, the clinical outcome of arrhythmia remains to be improved. According to the traditional Chinese medicine(TCM) theory, arrhythmia is a disease of palpitation induced by 7 conditions: liver depression and Qi stagnation, accumulation of turbid phlegm, fluid retention attacking the heart, fire-heat disturbing the heart, stasis obstruction of heart vessel, cold congealing in heart vessel, and the deficiency of Qi, blood, Yin, and Yang. Therefore, this study concisely proposed 7 TCM syndromes of arrhythmia, including the palpitation due to depression, phlegm, fluid retention, fire, blood stasis, cold, and deficiency. The corresponding treatment strategies were recommended as follows: Chaihu Longgu Muli Decoction for the palpitation due to depression, Wendan Decoction for the palpitation due to phlegm, Linggui Zhugan Decoction for the palpitation due to fluid retention, Sanhuang Xiexin Decoction for the palpitation due to fire, Xuefu Zhuyu Decoction for the palpitation due to blood stasis, and Mahuang Fuzi Xixin Decoction for the palpitation due to cold, and Guizhi Gancao Decoction, Guizhi Gancao Longgu Muli Decoction, Huanglian Ejiao Decoction, Zhigancao Decoction, and Guipi Decoction for the palpitation due to the deficiency of Qi, blood, Yin, and Yang. Multiple formulas should be combined if the patient presents several TCM syndromes simultaneously. According to the principles of the correspondence between formula and syndrome and the treatment with consideration to both pathogenesis and pathology and both herbal nature and pharmacology, this study proposed an integrated treatment model of "pathogenesis-pathology-nature-pharmacology" to enhance the clinical efficacy of classic herbal formulas in the treatment of arrhythmia.

The relationship between disease and syndrome is a research focus in integrated traditional Chinese and western medicine. Depending on the focus, the disease-syndrome combination for treatment is manifested as the different treatment methods for the same disease and the same treatment method for different diseases based on the syndrome, and different treatment methods for the same syndrome and the same treatment method for different syndromes based on the disease. The mainstream model is the combination of di-sease identification in modern medicine with syndrome identification and core pathogenesis in traditional Chinese medicine. However, current research on the combination of disease and syndrome and core pathogenesis tends to focus on the heterogeneity between disease and syndrome and the separation of syndrome and treatment. Therefore, the study proposed the research idea and model of core formulas-syndromes(CFS). According to the theory of formula-syndrome correspondence, the research idea of CFS deepens the research on core pathogenesis, which aims to summarize the core formulas and syndromes for diseases. The research fields include diagnostic criteria for the indications of formulas, distribution patterns of formulas and syndromes for diseases, the evolution of medicinal-syndrome based on formulas-syndromes, formula combination law based on formulas-syndromes, and the dynamic evolution of formulas-syndromes. Through the summary of ancient classics, clinical experience, and medical records, and with the methods of expert consultation, factor analysis, and clustering analysis, research on the diagnostic criteria for the indications of formulas aims to explore the diagnosis information such as the diseases, symptoms, signs, and pathophysiology. The research on the distribution patterns of formulas and syndromes for diseases tends to summarize the specific types of formulas and syndromes for the diseases through literature research and clinical cross-sectional studies based on the establishment of diagnostic criteria for the indications of formulas. The research on the evolution of medicinal-syndrome aims to clarify the medicinal-syndrome law through literature and clinical research. The formula combination law refers to the fact that the core prescriptions for a disease often appear in combination with other prescriptions on a regular basis. The dynamic evolution of formulas-syndromes refers to the continuous transformation and change of formulas and syndromes in the process of disease development with changes in time and space. The CFS is conducive to the unification of disease, syndrome and treatment and to the deepening of the research model of disease and syndrome integration.

Hypertension and its target organ damage have become a major public health problem. Sexual dysfunction is a new problem in the treatment of modern hypertension. Modern pathophysiological studies have shown that hypertension can lead to sexual dysfunction. In addition, three major hypotensive drugs represented by diuretics can also lead to sexual dysfunction. In traditional Chinese medicine(TCM), hypertension belongs to "vertigo" "headache" "head wind", etc. In the past, the understanding of the TCM pathogenesis of hypertension was mainly from the perspectives of "liver wind" and "Yang hyperactivity". However, based on the in-depth research on ancient and modern literature and medical records and many years of clinical practice, it has been identified that kidney deficiency was the key pathogenesis. Hypertension complicated with sexual dysfunction belongs to the category of kidney deficiency syndrome in TCM, especially the deficiency of kidney Yin. Previous studies by other research groups showed that Yin-enriching and kidney-tonifying method could effectively reduce blood pressure, improve sexual dysfunction, reverse risk factors, and protect target organs. This article systematically discussed the TCM understanding, modern pathophysiological mechanism, and the clinical treatment strategy of kidney-tonifying drugs(single drugs and compounds) in the treatment of hypertension complicated with sexual dysfunction in order to provide a scientific basis for kidney-tonifying method in the treatment of hypertension complicated with sexual dysfunction.

OBJECTIVE: To explore clinical effect of Scarf osteotomy combined with soft tissue balance in treating severe hallux valgus. METHODS: Totally 38 patients(50 feet) with severe hallux valux who underwent Scarf osteotomy combined with soft tissue balance surgery from June 2019 to June 2021 were retrospectively analyzed, aged from 29 to 64 years old with an average of(54.7±6.8) years old; 26 feet on the left side and 24 feet on the right side;the courses of disease ranged from 5 to 23 years with an average of (12.4±3.9) years. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA) were compared before and after operation, and postoperative complications was observed. American orthopedic foot ankle society(AOFAS) score before operation and final follow-up was used to evaluate recovery of forefoot function, and visual analogue scale (VAS) was used to evaluate pain relief. RESULTS: Thirty-eight patients (50 feet) were followed up from 15 to 23 months with an average of (18.3±3.2) months. Preoperative HVA, IMA and DMAA were (44.61±3.92)°, (18.74±2.51)°, (12.85±2.11)°, and improved to (13.45±2.13)°, (7.83±1.36)°, (7.03±1.39)°at final follow-up, which had statistical differneces(P<0.05). No delayed union or nonunion of osteotomy end, fracture or loosening of internal fixation, hallux varus occurred. VAS and AOFAS score improved from (6.81±2.14), (43.6±8.4)points before operation to (1.97±0.78), (87.6±5.2) points at final follow-up, which had statistical difference(P<0.01). According to AOFAS at final follow-up, 20 feet got excellent result, 28 feet good and 2 feet moderate. CONCLUSION Scarf osteotomy combined with soft tissue balance release for severe hallux valgus has good stability and corrective effect, but learning curve and postoperative complications should be paid attention.

Objective: To explore the relationship between obesity status and death stratified by different multi-morbidity status in older adults in China. Methods: Data for older Chinese adults aged ≥65 years were from Chinese Longitudinal Healthy Longevity Survey (CLHLS). Multi-morbidity patterns based on 13 chronic conditions were explored using exploratory factor analysis. Cox models were used to examine relationships between obesity status and death stratified by disease count and multi-morbidity patterns at baseline, respectively. Besides, obesity status was defined by baseline body mass index and waist circumference. Results: A total of 6 272 participants were included in the analyses. Multi-morbidity including cardio-metabolic, sensory perception and other patterns were identified. For those without any chronic condition, compared with those without central obesity, central obesity was associated with a higher risk for death (HR=1.66, 95%CI:1.04-2.66). For those only with one chronic condition, compared with normal weight, underweight was associated with a higher risk for death (HR=1.41, 95%CI: 1.10-1.80). For those with multi-morbidity, compared with normal weight, underweight increased the risk for death (HR=1.19, 95%CI:1.05-1.34). Compared with those without central obesity, central obesity decreased the risk for death (HR=0.88, 95%CI:0.78-0.99). Conclusions: Relationships between obesity status and death varied by multi-morbidity status in older adults in China. Underweight and non-central obesity were associated with increased risks for death in older adults with only one chronic disease or multi-morbidity. Therefore, it is necessary to pay attention to multi-morbidity status in the management of obesity in older adults and provide effective targeted body weight management plan.
