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.

Background: Obesity and chronic pain are related in both directions, according to earlier observational research.This research aimed to analyze the causal association between obesity and chronic pain at the genetic level, as well as to assess whether common factors mediate this relationship. Methods: This study used bidirectional two sample Mendelian randomization (MR) technique to analyze the association between obesity and chronic pain. Obesity's summary genome-wide association data were obtained from European ancestry groups, as measured by body mass index (BMI), waist-to-hip ratio, waist circumference (WC), and hip circumference (HC), genome-wide association study data for chronic pain also came from the UK population, including chronic pain at three different sites (back, hip, and headache), chronic widespread pain (CWP), and multisite chronic pain (MCP). Secondly, a two-step MR and multivariate MR investigation was performed to evaluate the mediating effects of several proposed confounders. Results: The authors discovered a link between chronic pain and obesity. More specifically, a sensitivity analysis was done to confirm the associations between greater BMI, WC, and HC with an increased risk of CWP and MCP.Importantly, the intermediate MR results suggest that education levels and smoking initiation may mediate the causal relationship between BMI on CWP, with a mediation effect of 23.08% and 15.38%, respectively. Conclusions The authors’ findings demonstrate that the importance of education and smoking in understanding chronic pain’s pathogenesis, which is important for the primary prevention and prognosis of chronic pain.

OBJECTIVE To investigate the effects and underlying mechanisms of Yiqi Huoxue Decoction(YQHX)on mitochon-drial midzone division and peripheral fission in myocardial tissue after myocardial infarction(MI).METHODS A total of 48 male SPF-grade C57BL/6N mice were randomly divided into a sham-operated group(Sham,n=12)and a left anterior descending coronary ar-tery ligation MI model(n=36).After MI surgery,mice deemed to have successfully developed the model were randomly divided into a model group(MI,n=12),a YQHX group(n=12),and an empagliflozin group(EMPA,n=12)based on echocardiographic results.Four weeks after infarction,cardiac function and structural changes were comprehensively evaluated using echocardiography imaging,serum myocardial injury biomarkers,and hematoxylin-eosin(HE)staining.Transmission electron microscopy(TEM)was employed to observe mitochondrial ultrastructural,morphological,and quantitative changes at the peri-infarct zone.Myocardial mitochondria and cytoplas-mic fractions were isolated from myocardial tissue using a mitochondrial extraction kit,and the spatial expression changes of mitochon-drial fission-related proteins in both mitochondria and cytoplasm of the peri-infarct myocardium were analyzed by Western blot.These proteins included dynamin-related protein 1(Drp1),its phosphorylated form at serine 616(P-Drp1-Ser616),mitochondrial fission fac-tor(MFF),and mitochondrial fission protein 1(Fis1).RESULTS Compared with the MI group,mice in the YQHX group exhibited sig-nificantly increased left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)(P<0.000 1),as well as decreased left ventricular internal dimension-diastole(LVIDd)and left ventricular end-systolic diameter(LVIDs)(P<0.05,P<0.01),suggesting improved cardiac function.Additionally,serum levels of lactate dehydrogenase(LDH)and creatine kinase-MB(CK-MB)were significantly reduced in the YQHX group(P<0.05,P<0.001),indicating cardio-protective effects of YQHX against ischemic in-jury.HE staining showed that YQHX improved cellular morphology,suggesting structural improvement.TEM showed that YQHX sig-nificantly improved mitochondrial swelling and reduced mitochondrial fragmentation in the marginal zone of myocardial infarction,thereby preserving mitochondrial ultrastructure.Furthermore,Western blot showed that YQHX treatment significantly downregulated P-Drp1-Ser616 expression(P<0.05)in the cytoplasm.Interestingly,YQHX treatment significantly downregulated mitochondrial Fis1 expression(P<0.05),thereby inhibiting peripheral mitochondrial fission.Meanwhile,YQHX treatment significantly increased MFF ex-pression in mitochondria(P<0.01),which may promote mitochondrial midzone fission.CONCLUSION YQHX improves cardiac structure and function after MI,potentially by promoting myocardial mitochondrial midzone fission and inhibiting mitochondrial periph-eral fission in ischemic cardiomyocytes.

Objective:To understand the basic information such as age,job title,and education of rehabilita-tion therapists in the Grade Ⅲ public psychiatric hospitals in China,and provide fundamental data for the construc-tion of the mental health rehabilitation talent team.Methods:The staffing of rehabilitation therapists in 43 Grade Ⅲpublic psychiatric hospitals in eastern,central,and western regions of China were investigated.The age,education,job title,professional relevance and inter-regional differences of the rehabilitation therapists were statistically ana-lyzed.Results:There were 197 rehabilitation therapists in 43 hospitals surveyed.The age distribution was mainly in 20-30 and 30-40 years old with a bachelor's degree and junior,and more than half of the personnel had their first academy degree related to the rehabilitation profession.The differences in age,education,job title were statistically significant in the eastern,central and western regions.Conclusion:The overall quality of the rehabilitation therapists in China's Grade Ⅲ public psychiatric hospitals is relatively high,and the age structure is reasonable.However,the proportion of senior professional titles is relatively low.Therefore,it is necessary to focus on talent training and the establishment of promotion systems in the future,in order to improve the professional development space and level of the entire industry.

Objective:To investigate the clinical effects of Meek skin grafting combined with platelet-rich plasma (PRP) in repairing of extensive deep burn wounds.Methods:This study was a retrospective observational study. From August 2018 to August 2023, 44 patients who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 23 males and 21 females. Their age ranged from 22 to 62 years and the total burn area was 30%-80% total body surface area, the burns on limbs or torso were deep partial-thickness to full-thickness. According to the treatment process of deep burns on the limbs or torso, the patients were divided into observation group (21 cases) and control group (23 cases). patients in observation group were treated with Meek skin grafting combined with PRP at the same time, while patients in control group were treated with Meek skin grafting alone. The survival of Meek skin grafts was observed on the 10 th day after operation. The wound healing rate in the operation area of patients was observed on the 14 th day after operation. The postoperative wound healing time and positive rate of bacterial culture of wound secretion specimens were recorded. Results:On the 10 th day after operation, the skin grafting area of patients in observation group were dry, and the skin grafts adhered closely to the wound base with ruddy color, with a survival rate of (89±4)%; whereas in control group, some of Meek skin grafts fell off in the skin graft area, and the residual wounds were scattered in irregular map shape, accompanied by purulent secretions. The survival rate of skin grafts was (79±6)%, which was significantly lower than that in observation group ( t=6.72, P<0.05). On the 14 th day after operation, 19 patients in observation group had complete wound healing in the operation area, and the other 2 patients had small residual wounds, which healed after 1 week delay through dressing changes; in control group, the wounds in 12 patients healed completely, the wounds in 6 patients healed after supplementary stamp skin grafting, and the wounds in 5 patients healed with delay after routine dressing changes. The wound healing rate was significantly lower than that in observation group ( P<0.05). After operation, the wound healing time of the operation area of patients in observation group was (13.3±1.6) days, which was significantly shorter than (16.4±3.5) days in control group ( t=3.72, P<0.05); there was no statistically significant difference in the positive rate of bacterial culture of wound secretion specimens between observation group and control group after operation ( P>0.05). Conclusions:Compared with Meek skin grafting alone, Meek skin grafting combined with autologous PRP can promote the survival of skin grafts, accelerate the expansion and fusion of skin grafts, and shorten the wound healing time, thereby improving the therapeutic effect in the repairing of extensive deep burn wounds.
