OBJECTIVE: To observe the clinical efficacy of acupuncture based on "status-target coherence" theory combined with Kegel exercises for vaginal laxity syndrome (VLS). METHODS: Sixty-six patients with VLS were randomized into an observation group (33 cases, 2 cases dropped out, 1 case was discontinued) and a control group (33 cases, 5 cases dropped out). The observation group was treated with acupuncture combined with Kegel exercises, acupuncture was applied to bilateral Ciliao (BL32), Zhongliao (BL33), Sanyinjiao (SP6), etc. The control group was treated with Kegel exercises. Both acupuncture and Kegel exercises were performed once every other day, three times a week for 12 weeks. Before and after treatment, the vaginal laxity questionnaire (VLQ) score, pelvic floor muscle strength (vaginal resting pressure, vaginal systolic pressure, vaginal contraction duration), degree of vaginal laxity and sexual satisfaction questionnaire (SSQ) grade were observed in both groups. RESULTS: After treatment, the VLQ score, vaginal resting pressure, vaginal systolic pressure, vaginal contraction duration in the observation group were elevated compared with those before treatment (P<0.05), and SSQ grade was improved (P<0.05); and the above indexes in the observation group were better than those in the control group (P<0.05). There were no significant difference before and after treatment in the degree of vaginal laxity in the two groups (P>0.05). CONCLUSION Acupuncture based on "status-target coherence" theory combined with Kegel exercises can effectively enhance the strength of pelvic floor muscles, improve the symptoms of vaginal laxity, and improve the satisfaction of sexual life, and its therapeutic effect is better than Kegel exercises alone.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

OBJECTIVE: To investigate the Wnt signaling pathway and miRNAs mechanism of extracts of Plastrum Testudinis (PT) in the treatment of osteoporosis (OP). METHODS: Thirty female Sprague Dawley rats were randomly divided into 5 groups by random number table method, including sham group, ovariectomized group (OVX), ovariectomized groups treated with high-, medium-, and low-dose PT (160, 80, 40 mg/kg per day, respectively), with 6 rats in each group. Except for the sham group, the other rats underwent bilateral ovariectomy to simulate OP and received PT by oral gavage for 10 consecutive weeks. After treatment, bone mineral density was measured by dual-energy X-ray absorptiometry; bone microstructure was analyzed by micro-computed tomography and hematoxylin and eosin staining; and the expressions of osteogenic differentiation-related factors were detected by immunochemistry, Western blot, and quantitative polymerase chain reaction. In addition, Dickkopf-1 (Dkk-1) was used to inhibit the Wnt signaling pathway in bone marrow mesenchymal stem cells (BMSCs) and miRNA overexpression was used to evaluate the effect of miR-214 on the osteogenic differentiation of BMSCs. Subsequently, PT extract was used to rescue the effects of Dkk-1 and miR-214, and its impacts on the osteogenic differentiation-related factors of BMSCs were evaluated. RESULTS: PT-M and PT-L significantly reduced the weight gain in OVX rats (P<0.05). PT also regulated the bone mass and bone microarchitecture of the femur in OVX rats, and increased the expressions of bone formation-related factors including alkaline phosphatase, bone morphogenetic protein type 2, collagen type I alpha 1, and runt-related transcription factor 2 when compared with the OVX group (P<0.05 or P<0.01). Meanwhile, different doses of PT significantly rescued the inhibition of Wnt signaling pathway-related factors in OVX rats, and increased the mRNA or protein expressions of Wnt3a, β-catenin, glycogen synthase kinase-3β, and low-density lipoprotein receptor-related protein 5 (P<0.05 or P<0.01). PT stimulated the osteogenic differentiation of BMSCs inhibited by Dkk-1 and activated the Wnt signaling pathway. In addition, the expression of miR-214 was decreased in OVX rats (P<0.01), and it was negatively correlated with the osteogenic differentiation of BMSCs (P<0.01). MiR-214 mimic inhibited Wnt signaling pathway in BMSCs (P<0.05 or P<0.01). Conversely, PT effectively counteracted the effect of miR-214 mimic, thereby activating the Wnt signaling pathway and stimulating osteogenic differentiation in BMSCs (P<0.05 or P<0.01). CONCLUSION PT stimulates bone formation in OVX rats through β-catenin-mediated Wnt signaling pathway, which may be related to inhibiting miR-214 in BMSCs.

Aim To investigate the preventive and therapeutic effects of the mfat-1 gene therapy on exper-imental autoimmune encephalomyelitis in mice.Meth-ods mfat-1 gene therapy was used to render the host endogenous capability of producing ω-3 PUFAs,con-comitantly reduce the levels of ω-6 PUFAs,and change the proportion of ω-3/ω-6 PUFAs.Then,the levels of PUFAs in blood were analyzed by gas chromatography.The neurological deficits in mice were evaluated by neurological dysfunction score.HE staining and LFB staining of mouse spinal cord slices were used to ob-serve central nervous system inflammation infiltration and demyelinating lesions.Flow cytometry microsphere microarray technology was used to detect the content of cytokines in serum.Results The mfat-1 gene therapy could significantly raise the proportion of ω-3/ω-6 PU-FAs(P＜0.05),markedly delay the incubation period and peak period and reduce neurological dysfunction scores(P＜0.05),and improve inflammation and de-myelination of spinal cords(P＜0.05).It could also greatly increase the levels of IL-2,IFN-γ,IL-4 and IL-17 in serum(P＜0.05).Conclusion The pro-portion of ω-3/ω-6 PUFAs in blood circulation en-hanced by mfat-1 gene therapy can effectively prevent and treat experimental autoimmune encephalomyelitis in mice.

Objective This study aimed to understand the epidemic status and phylogenetic relationships of rotavirus group A(RVA)in the Pearl River Delta region of Guangdong Province,China. Methods This study included individuals aged 28 days-85 years.A total of 706 stool samples from patients with acute gastroenteritis collected between January 2019 and January 2020 were analyzed for 17 causative pathogens,including RVA,using a Gastrointestinal Pathogen Panel,followed by genotyping,virus isolation,and complete sequencing to assess the genetic diversity of RVA. Results The overall RVA infection rate was 14.59%(103/706),with an irregular epidemiological pattern.The proportion of co-infection with RVA and other pathogens was 39.81%(41/103).Acute gastroenteritis is highly prevalent in young children aged 0-1 year,and RVA is the key pathogen circulating in patients 6-10 months of age with diarrhea.G9P[8](58.25%,60/103)was found to be the predominant genotype in the RVA strains,and the 41 RVA-positive strains that were successfully sequenced belonged to three different RVA genotypes in the phylogenetic analysis.Recombination analysis showed that gene reassortment events,selection pressure,codon usage bias,gene polymorphism,and post-translational modifications(PTMs)occurred in the G9P[8]and G3P[8]strains. Conclusion This study provides molecular evidence of RVA prevalence in the Pearl River Delta region of China,further enriching the existing information on its genetics and evolutionary characteristics and suggesting the emergence of genetic diversity.Strengthening the surveillance of genotypic changes and gene reassortment in RVA strains is essential for further research and a better understanding of strain variations for further vaccine development.

Objective The leptin receptor,encoded by the LEPR gene,is involved in tumorigenesis.A potential functional variant of LEPR,rs1137101(Gln223Arg),has been extensively investigated for its contribution to the risk of digestive system(DS)cancers,but results remain conflicting rather than conclusive.Here,we performed a case-control study and subsequent meta-analysis to examine the association between rs1137101 and DS cancer risk. Methods A total of 1,727 patients with cancer(gastric/liver/colorectal:460/480/787)and 800 healthy controls were recruited.Genotyping of rs1137101 was conducted using a polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)assay and confirmed using Sanger sequencing.Twenty-four eligible studies were included in the meta-analysis. Results After Bonferroni correction,the case-control study revealed that rs1137101 was significantly associated with the risk of liver cancer in the Hubei Chinese population.The meta-analysis suggested that rs1137101 is significantly associated with the risk of overall DS,gastric,and liver cancer in the Chinese population. Conclusion The LEPR rs1137101 variant may be a genetic biomarker for susceptibility to DS cancers(especially liver and gastric cancer)in the Chinese population.

Objective To understand the consumption of hand hygiene(HH)products and HH compliance in in-tensive care units(ICUs)of secondary and higher grade medical institutions(MIs)in Shanghai,and provide basis for further monitoring of HH among health care workers(HCWs).Methods Through healthcare-associated infec-tion surveillance system,the consumption of HH products and HH compliance in ICUs from secondary and higher grade MIs in Shanghai in 2017-2021 were analyzed.Results 105 ICUs from 74 MIs were included in analysis,the average consumption of HH products was 79.24(44.88-258.63)mL/(bed·day),with statistically significant difference among different types of ICUs(P＜0.001).The average consumption of HH products increased from 65.75 mL/(bed·day)in 2017 to 87.55 mL/(bed·day)in 2021,showing an increasing trend year by year(P＜0.001).HCWs'HH compliance rate was 82.13％,with the highest in nurses(86.59％)and the lowest(48.90％)in medical technicians,HH compliance rates of HCWs of different occupations were statistically significant different(P＜0.001).Among the implementation modes of HH,39.86％used running water for hand washing,42.27％used alcohol-based hand rub to wipe hands,13.22％didn't take HH measures,and 4.65％didn't take HH mea-sures when wearing gloves,with statistically significant differences among different HH implementation modes of HCWs(P＜0.001).There was a positive correlation between the average consumption of HH products per bed·day and HCWs'HH compliance rate(r=0.703,P＜0.05).Conclusion The average consumption of HH products per bed·day and HH compliance rate of HCWs in ICUs in Shanghai presents an increasing trend year by year.There are differences in the average consumption of HH products per bed·day and HH compliance rate among different types of ICUs.The implementation of HH can be evaluated by continuously surveillance on the average consumption of HH products per bed·day.

OBJECTIVE: To investigate the effects of the B7-H4 gene rs10754339 and miR-125a gene rs12976445 on cancer susceptibility through a case-control study and meta-analysis. METHODS: A total of 1,490 cancer patients (lung/gastric/liver/: 550/460/480) and 800 controls were recruited in this case-control study. The meta-analysis was performed by pooling the data from previous related studies and the present study. RESULTS: The results of this study showed that in the Hubei Han Chinese population, the rs10754339 gene was significantly associated with the risk of lung and gastric cancer but not liver cancer, and the rs12976445 gene was significantly associated with the risk of lung cancer but not liver or gastric cancer. The meta-analysis results indicated that rs10754339 and rs12976445 contributed to cancer susceptibility in the Chinese population and also revealed a significant association between rs10754339 and breast cancer risk, as well as between rs12976445 and lung cancer risk. CONCLUSION The B7-H4 gene rs10754339 and miR-125a gene rs12976445 may be the potential genetic markers for cancer susceptibility in the Chinese population, which should be validated in future studies with larger sample sizes in other ethnic populations.
