Objective To analyze the epidemiological characteristics and epidemic situation of children with Kashin-Beck disease (KBD) in China,and provide the basis for formulating prevention and control measures. Methods Fixed-point monitoring,moving-point monitoring,and full coverage of monitoring were promoted successively from 1990 to 2023. Some children (7-12 years old) underwent clinical and right-hand X-ray examinations every year. According to the KBD diagnosis criteria,clinical and X-ray assessments were used to confirm the diagnosis. Results In 1990,the national KBD detectable rate was 21.01％. X-ray detection decreased to below 10％ in 2003 and below 5％ in 2007. Between 2010 and 2018,the prevalence of KBD in children was less than 0.4％,which fluctuated at a low level,and has decreased to 0％ since 2019. Spatial epidemiological analysis indicated a spatial clustering of adult patients prevalence rate in the KBD areas. Conclusion The evaluation results of the elimination of KBD in China over the last 5 years showed that all villages in the monitored areas have reached the elimination standard. While the adult KBD patients still need for policy consideration and care.

Objective:To explore the prospective associations between physical activity and incident ischemic stroke in adults.Methods:Data of China Kadoorie Biobank study in Tongxiang of Zhejiang were used. After excluding participants with cancers, strokes, heart diseases and diabetes at baseline study, a total of 53 916 participants aged 30-79 years were included in the final analysis. The participants were divided into 5 groups according to the quintiles of their physical activity level. Cox proportional hazard regression models was used to calculate the hazard ratios ( HR) for the analysis on the association between baseline physical activity level and risk for ischemic stroke. Results:The total physical activity level in the participants was (30.63±15.25) metabolic equivalent (MET)-h/d, and it was higher in men [(31.04±15.48) MET-h/d] than that in women [(30.33±15.07) MET-h/d] ( P<0.001). In 595 526 person-years of the follow-up (average 11.4 years), a total of 1 138 men and 1 082 women were newly diagnosed with ischemic stroke. Compared to participants with the lowest physical activity level (<16.17 MET-h/d), after adjusting for socio-demographic factors, lifestyle, BMI, waist circumference, and SBP, the HRs for the risk for ischemic stroke in those with moderate low physical activity level (16.17-24.94 MET-h/d), moderate physical activity level (24.95-35.63 MET-h/d), moderate high physical activity level (35.64-43.86 MET-h/d) and the highest physical activity level (≥43.87 MET-h/d) were 0.93 (95% CI: 0.83-1.04), 0.87 (95% CI: 0.76-0.98), 0.82 (95% CI: 0.71-0.95) and 0.76 (95% CI: 0.64-0.89), respectively. Conclusion:Improving physical activity level has an effect on reducing the risk for ischemic stroke.

The incidence of male infertility has been increasing year by year,and one of the major causes is testicular spermato-genic epithelial injury,which affects the spermatogenic function of the testis.Ferroptosis is a novel mode of cell death and plays an im-portant role in testicular cell injury.Some traditional Chinese medicines can intervene in the progression of testicular injury by regula-ting the ferroptosis pathway in testicular spermatogenic epithelia.This paper focuses on the effect of traditional Chinese drugs in regula-ting the ferroptosis pathway in testicular cells,and summarizes the advances in the studies of traditional Chinese medicines in the treat-ment of testicular spermatogenic epithelial injury,aiming to provide a theoretical basis for the selection of relevant medicines and their clinical application.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Objective:To investigate the dynamic prevalence of Kashin-Beck disease (KBD) in 2020, and to provide the basis for assessment of KBD control and elimination.Methods:According to the "Kashin-Beck Disease Monitoring Plan (2019 Edition)", collection of basic information of endemic areas and children KBD examination were executed in all endemic areas from every endemic county (city, district, banner) of 13 endemic provinces. All children aged 7 - 12 years in endemic areas underwent clinical examination, X-ray examination was performed for clinically positive children. According to the criteria of "Diagnosis of Kashin-Beck Disease" (WS/T 207-2010), KBD cases were diagnosed by both clinical examination and X-ray check.Results:In monitoring of 827 986 children of 7 - 12 years old, a total of 703 children with similar clinical signs of KBD were suspected positive cases. X-ray results showed that 703 children were normal, with no X-ray positive change, they were not children KBD cases.Conclusions:In 2020, no cases of Kashin-Beck disease are detected in children nationwide, and the condition of Kashin-Beck disease in children nationwide continues to be at a level of elimination.

BACKGROUND: Existing evidence suggests that fruit consumption is a significant influencing factor for chronic obstructive pulmonary disease (COPD), but this is unclear in the Chinese population. We examined the association of fresh fruit consumption with the risk of COPD-related hospitalization and death in a nationwide, population-based prospective cohort from China. METHODS: Between 2004 and 2008, the China Kadoorie Biobank recruited >0.5 million adults aged 30 to 79 years from ten diverse regions across China. After excluding individuals diagnosed with major chronic diseases and prevalent COPD, the prospective analysis included 421,428 participants. Cox regression was used to calculate the hazard ratios (HRs) for the association between fresh fruit consumption and risk of COPD-related hospitalization and death, with adjustment for established and potential confounders. RESULTS: During a mean follow-up of 10.9 years, 11,292 COPD hospitalization events and deaths were documented, with an overall incidence rate of 2.47/1000 person-years. Participants who consumed fresh fruit daily had a 22% lower risk of COPD-related hospitalization and death compared with non-consumers (HR = 0.78, 95% confidence interval [CI]: 0.71-0.87). The inverse association between fresh fruit consumption and COPD-related hospitalization and death was stronger among non-current smokers and participants with normal body mass index (BMI) (18.5 kg/m 2 ≤ BMI < 24.0 kg/m 2 ); the corresponding HRs for daily fresh fruit consumption were 0.78 (95% CI: 0.68-0.89) and 0.69 (95% CI: 0.59-0.79) compared with their counterparts, respectively. CONCLUSIONS High-frequency fruit consumption was associated with a lower risk of COPD in Chinese adults. Increasing fruit consumption, together with cigarette cessation and weight control, should be considered in the prevention and management of COPD.

Abstract: Objective　To explore the early diagnostic value of peripheral blood peroxisome proliferator-activated receptor γ (PPARγ) combined with γ-interferon (IFN-γ) release assay (IGRA) in the diagnosis of pulmonary tuberculosis in patients with end-stage renal disease (ESRD), and to provide reference for clinical diagnosis and treatment. Methods　From January 2019 to December 2021, 70 ESRD patients with suspicious symptoms of pulmonary tuberculosis were treated at Hebei Chest Hospital were selected as the research objects. According to the examination results, they were divided into ESRD group (40 cases) and ESRD complicated by pulmonary tuberculosis (40 cases, comorbidity group). In addition, 40 cases with pulmonary tuberculosis were used as the PTB group. All three groups of patients underwent IGRA test, and the peripheral blood PPARγ level was detected by enzyme-linked immunosorbent assay, and the diagnostic value of PPARγ combined with IGRA test for ESRD patients with pulmonary tuberculosis was explored. Results The expression level of PPARγ and IFN-γ content in the PTB group and the comorbidity group were obviously higher than those in the ESRD group (P<0.05), while the differences in PPARγ expression level and IFN-γ content between the PTB and comorbidity groups were not statistically significant (P>0.05). The ROC curve showed that the areas under the curve (AUC) of PPARγ and IGRA in the diagnosis of end-stage renal disease combined with tuberculosis were 0.823 (95%CI: 0.722-0.925) and 0.773 (95%CI: 0.662-0.883), respectively, and the AUC of combined detection was 0.928 (95%CI: 0.871-0.984), which was better than that of PPARγ and IGRA alone (Z/P=2.057/0.039, 2.843/0.005). The Kappa values of serum PPARγ and IGRA test compared with the clinical gold standard results in the diagnosis of ESRD complicated with pulmonary tuberculosis were 0.557 and 0.444 (P<0.05). The combined screening of ESRD with pulmonary tuberculosis was consistent with the clinical gold standard (Kappa=0.661, P<0.05). Among the 30 ESRD patients complicated with pulmonary tuberculosis, the sensitivity of PPARγ combined with IGRA test in diagnosis of ESRD complicated with pulmonary tuberculosis was 93.33% (28/30), which was higher than 70.00% (21/30) of PPARγ and 66.67% (20/30) of IGRA test alone (P<0.05). Conclusions Peripheral blood PPARγ and IGRA tests have certain diagnostic value for ESRD complicated with tuberculosis, and the combined detection of the two can improve the sensitivity and reduce the rate of missed diagnosis, which is worthy of clinical promotion.

OBJECTIVE: To observe the clinical significance of translocator proteins (TSPO) gene in the treatment of FLT3-ITD/DNMT3A R882 double-mutated acute myeloid leukemia (AML). METHODS: Seventy-six patients with AML hospitalized in the Department of Hematology of the Affiliated People's Hospital of Ningbo University from June 2018 to June 2020 were selected, including 34 patients with FLT3-ITD mutation, 27 patients with DNMT3A R882 mutation, 15 patients with FLT3-ITD/DNMT3A R882 double mutation, as well as 19 patients with immune thrombocytopenia (ITP) hospitalized during the same period as control group. RNA was routinely extracted from 3 ml bone marrow retained during bone puncture, and TSPO gene expression was detected by transcriptome sequencing (using 2-deltadeltaCt calculation). RESULTS: The expression of TSPO gene in FLT3-ITD group and DNMT3A R882 group at first diagnosis was 2.02±1.04 and 1.85±0.76, respectively, which were both higher than 1.00±0.06 in control group, but the differences were not statistically significant (P=0.671, P=0.821). The expression of TSPO gene in the FLT3-ITD/DNMT3A R882 group was 3.98±1.07, wich was significantly higher than that in the FLT3-ITD group and DNMT3A R882 group, the differences were statistically significant (P=0.032, P=0.021). The expression of TSPO gene in patients who achieved complete response after chemotherapy in the FLT3-ITD/DNMT3A R882 group was 1.19±0.87, which was significantly lower than that at first diagnosis, and the difference was statistically significant (P=0.011). CONCLUSION TSPO gene may be used as an indicator of efficacy in FLT3-ITD /DNMT3A R882 double-mutated AML.
