Background::Atopic dermatitis (AD) is a chronic inflammatory skin disorder impacting populations worldwide, although its clinical characteristics and patient demographics remain uncharacterized in China. The aim of this study was to investigate the demographics, comorbidities, aggravating factors, and treatments in AD patients across different age groups in China.Methods::This cross-sectional study included Chinese AD patients from 205 hospitals spanning 30 provinces. Patients completed dermatologist-led surveys of general medical history, comorbidities, AD-related aggravating factors, and medications. Two-level mixed-ordered logistic regression was used to evaluate aggravating factors.Results::Overall, 16,838 respondents were included in the final analysis (aged 30.9 ± 24.1 years). The proportion of severe AD was the highest in patients with AD onset at ≥60 years (26.73%). Allergic rhinitis and hypertension were the most common atopic and metabolism-related non-atopic comorbidities, respectively. AD severity was significantly associated with chronic urticaria, food allergies, and diabetes. Aggravating factors including foods, seasonal changes, and psychological factors were also linked to AD severity. The cross-sectional survey implied that severe AD may be related to the undertreatment of effective systemic or topical interventions.Conclusion::To enhance the management of AD, it is crucial to consider both aggravating factors and the increased utilization of systemic immunotherapy.Registration::ClinicalTrials.gov, NCT05316805

Objective:To evaluate the differences in total effectiveness, Visual Analogue Scale (VAS) scores, and Cox Menstrual Symptom Scale (CMSS) scores among four non-invasive Traditional Chinese Medicine (TCM) techniques: moxibustion, massage therapy, acupoint application, and auricular acupressure, for the care of primary dysmenorrhea (PD) using network Meta-analysis, providing evidence-based guidance for clinical decision-making.Methods:Randomized controlled trials (RCTs) involving the four non-invasive TCM techniques for PD care were retrieved from databases including China National Knowledge Infrastructure, VIP, Wanfang, SinoMed, PubMed, Embase, Web of Science, and Cochrane Library up to November 30, 2023. Network Meta-analysis was conducted using RevMan 5.4 and Stata 17.0.Results:A total of 83 studies involving 8 370 PD patients were included. The network Meta-analysis showed that all four TCM techniques were superior to control measures in terms of total effectiveness and reducing VAS scores. Moxibustion, acupoint application, and auricular acupressure were also superior in reducing CMSS scores. Ranking of the effects of different interventions: total effectiveness: auricular acupressure > moxibustion > acupoint application > massage therapy > acupuncture > Chinese patent medicine > Western medicine > blank control > placebo treatment; VAS scores: moxibustion > auricular acupressure > acupoint application > acupuncture > placebo treatment > massage therapy > Western medicine > Chinese patent medicine > blank control; CMSS scores: auricular acupressure > moxibustion > acupuncture > placebo treatment > acupoint application > Western medicine > blank control.Conclusions:The four non-invasive TCM techniques have significant advantages in PD care, with auricular acupressure and moxibustion being the preferred choices for clinical care.

Objective: To explore the effect of replacing rice bowls with trays on controlling the salt intake among school aged children, providing new evidence and insights for salt reduction intervention. Methods: From April to May 2024, 373 students from grades 4-9 at a boarding school in Guizhou Province were enrolled through stratified random cluster sampling, with one intervention class and one control class per grade. During the intervention period for one month, and the types of meals provided, pricing standards, and dining procedures shall remain consistent with daily operations, the intervention group ( n =181) compartmentalized trays for lunch and dinner, while the control group ( n =192) still used a rice bowl. Pre and post intervention assessments included 24 hour urine collection, questionnaire surveys, and physical measurements. The difference in differences analysis combined with multiple linear regression was used to analyze the changes in sodium intake and to evaluate the net effect of the intervention. Results: The post intervention 24 hour sodium intake in the intervention group was ( 2 222.6 ±1 013.6) mg, an increase of 94.6 mg from baseline, with no statistically significant difference ( t=1.10, P >0.05). In contrast, the post intervention 24 hour sodium intake in the control group was (2 080.5±895.7) mg, a decrease of 190.8 mg from baseline, showing a statistically significant difference ( t=-2.39, P <0.05). The difference in differences results indicated that after adjusting the model for factors such as gender, grade and dietary behaviors affecting sodium intake, the intervention group showed a net increase of 232.5 mg [ β(95%CI )=232.5(-40.3-505.2)] in 24 hour sodium intake compared to the control group, with no statistically significant net effect ( P >0.05). Conclusions Merely changing tableware is insufficient to control children s salt intake effectively. Based on continuous practical explorations and evidence based research grounded in the nudge theory, multi dimensional measures such as salt reduction education and the construction of a supportive environment should be integrated to form an intervention system that achieves synergistic and enhanced effects.

OBJECTIVE: To compare the clinical efficacy of electroacupuncture (EA) at neuro-arterial stimulation points with topical western medication in treating post-stroke shoulder-hand syndrome (SHS). METHODS: A total of 72 patients with post-stroke SHS were randomly assigned to an observation group (n=36, 2 cases dropped out) and a control group (n=36, 3 cases dropped out). Both groups received standard neurological treatment, comprehensive rehabilitation, and physical therapy. The observation group received EA at neuro-arterial stimulation points, including the ipsilateral stellate ganglion point, vagus nerve trunk and auricular branch (left side), and stimulation points of the radial and ulnar arteries, radial nerve, ulnar nerve, and median nerve, once daily for 4 weeks. The control group was treated with topical diclofenac diethylamine emulgel, and mucopolysaccharide polysulfate cream was added for patients with pronounced early-stage edema, twice a day for 4 weeks. The VAS pain score and hand edema volume were recorded before treatment, at 2 and 4 weeks during treatment, and 2 weeks after treatment completion (follow-up). Musculoskeletal ultrasound was used to measure the thickness of the dorsal hand and middle finger skin on the affected side before and after 4 weeks of treatment. RESULTS: Compared before treatment, the VAS pain scores and edema volume of the affected hand in both groups were decreased at week 2, week 4, and follow-up (P<0.05). At week 4, both groups showed lower VAS pain scores and edema volume than those at week 2 (P<0.05); during follow-up, both VAS pain scores and edema volume were further reduced compared to those at week 4 (P<0.05). At week 2, week 4, and follow-up, the VAS scores and edema volume of the affected hand in the observation group were lower than those in the control group (P<0.05). Compared before treatment, the dorsal hand skin thickness and middle finger skin thickness on the affected side were decreased in both groups after 4 weeks of treatment (P<0.05). Compared with the control group, the observation group showed thinner dorsal hand and middle finger skin thickness after 4 weeks of treatment (P<0.05). CONCLUSION EA at neuro-arterial stimulation points effectively alleviates pain and edema in patients with post-stroke SHS, and demonstrates superior efficacy compared to topical western medication.

[Objective]To investigate the regulatory effect and potential mechanisms of isocitrate dehydrogenase 3A(IDH3A)on cardiomyocyte hypertrophy.[Methods]The expression of IDH3A in the myocardium of healthy volunteers(n=10)and patients with heart failure(HF)(n=10),and in the myocardium of mice subjected to transverse aortic constriction(TAC)surgery and sham operation,as well as in phenylephrine(PE)-induced neonatal rat ventricular cardiomyocytes(NRVCs),was assessed by real-time quantitative polymerase chain reaction(RT-qPCR)and Western blot assay.The effect of adenovirus-mediated overexpression of IDH3A on the expression of hypertrophy-related genes in PE-induced NRVCs was also evaluated.The effect of IDH3A on NRVCs area was examined by phalloidin staining assay.A mutant of IDH3A with abolished enzymatic activity,IDH3A_D208A,was generated through site-directed mutagenesis.The impact of this IDH3A mutant on the hypertrophic phenotype,ATP and ROS levels in NRVCs was evaluated to investigate whether the regulatory role of IDH3A in cardiomyocyte hypertrophy was dependent on its enzymatic activity.The effect of exogenous α-ketoglutaric acid(AKG)on cardiomyocyte hypertrophy was also detected by Western blot and phalloidin staining assay,respectively.[Results]IDH3A was significantly decreased in the myocardium of HF patients,in the myocardium of TAC-operated mice,and in PE-induced NRVCs(P=0.005 2,P=0.026 6,P=0.041 3 and P=0.006 6,respectively).Overexpression of IDH3A markedly suppressed the expression of hypertrophy-related genes and the increase of cell size of PE-induced NRVCs(P<0.000 1,P=0.000 1 and P=0.000 2,respectively).The ATP and ROS analysis indicated that IDH3A inhibited the increases of ATP and ROS levels in PE-induced NRVCs(P=0.001 2 and P<0.000 1,respectively),whereas the enzymatically inactive IDH3A mutant lacked this effect.Exogenous AKG provision could,but overexpression of IDH3A mutant failed to suppress PE-induced NRVCs hypertrophy.[Conclusion]IDH3A inhibits cardiomyocyte hypertrophy via elevating AKG level,providing scientific evidence for study on IDH3A-based treatment of cardiac hypertrophy.
