Objective To evaluate the clinical efficacy of Shengyang Juxian Acupuncture Method(mainly with the function of elevating yang to cure prolapse syndrome)combined with neuromuscular electrical stimulation(NMES)in treating postpartum diastasis recti abdominis(DRA).Methods A total of 200 patients diagnosed with postpartum DRA at Tangshan Maternal and Child Health Hospital from March 2022 to December 2022 were enrolled and randomly divided into an observation group and a control group using a number list,with 100 cases in each group.The control group received NMES therapy,while the observation group underwent additional Shengyang Juxian Acupuncture Method for 1 month.Clinical efficacy was assessed by comparing inter-recti distance(IRD),abdominal circumference,pelvic floor muscle strength(type Ⅰ and Ⅱ muscle fibers).The Visual Analogue Scale(VAS)scores for low back pain,and 36-Item Short Form Health Survey(SF-36)scores were compared before and after treatment.Results(1)After treatment,both groups showed significant improvements in IRD and abdominal circumference(P＜0.05),with superior outcomes in the observation group,the difference being statistically significant(P＜0.05).(2)Pelvic floor muscle strength of type Ⅰ and Ⅱ fibers markedly improved in both groups,with greater enhancement in the observation group,the difference being statistically significant(P＜0.05).(3)VAS and SF-36 scores significantly improved in both groups(P＜0.05),yet the observation group demonstrated more pronounced improvements,the difference being statistically significant(P＜0.05).(4)The total effective rate was 96.00%(96/100)in the observation group versus 80.00%(80/100)in the control group,with superior outcomes in the observation group,the difference being statistically significant(P＜0.05).Conclusion Shengyang Juxian Acupuncture Method combined with NMES effectively promotes rectus abdominis recovery,enhances pelvic floor muscle strength,alleviates low back pain,and improves quality of life in postpartum DRA patients,demonstrating significant clinical efficacy.

Objective To investigate whether transcutaneous electrical acupoint stimulation(TEAS)can improve the muscle strength,endurance and work efficiency of calf muscles in healthy young men,aiming to explore a new method for preventing and combating microgravity-induced muscle atrophy in space environments.Methods 40 healthy young men aged 18-35 years were randomly divided into a Control group(Pseudo Transcutaneous Electrical Acupoint Stimulation)and a Experimental group(Transcutaneous Electrical Acupoint Stimulation)in a 1∶1 ratio,with 20 participants in each group.In the Control group,the indicator light of the stimulator was covered,and the device was turned on,but the electrodes did not contact the skin,The device automatically turned offafter 3 seconds.In the Experimental group,the TEAS device was connected to the current and TEAS intervention was performed.The electrical stimulation waveform was a sperse-dense wave with a frequency of 4/20 Hz,and the intensity was determined by patient tolerance.The acupoints selected for electrical stimulation in both groups were bilateral Zusanli(ST36)、Liangqiu(ST34),Taixi(KI3),and Fuliu(KI7).Zusanli and Liangqiu were paired,and Taixi and Fuliu were paired.The intervention frequency was 30 min/time,1 time/day,6 days/week,for 2 weeks.The relative peak torque at 60°/s,relative peak torque at 180°/s,and average power at 180°/s of the bilateral calf muscles were measured using an isokinetic dynamometer at 0th,7th,and 14d day of the experiment.Results After 1 week of TEAS,compared with Control group,there were no significant changes in the relative peak torque at 60°/s,relative peak torque at 180°/s and average power at 180°/s of the bilateral anterior calf muscles in the Experimental group(all P>0.05);however,compared with Control group,the relative peak torque at 60°/s and the relative peak torque at 180°/s of the bilateral posterior calf muscles in the Experimental group were significantly increased(all P<0.05).After 2 weeks TEAS;compared with the Control group,there were no significant changes in the relative peak torque at 60°/s,relative peak torque at 180°/s and average power at 180°/s of the bilateral anterior calf muscles in the Experimental group(all P>0.05);however,the relative peak torque at 60°/s,relative peak torque at 180°/s,and average power at 180°/s of the bilateral posterior calf muscles were significantly increased in the Experimental group(all P<0.05).Conclusion TEAS of Zusanli,Liangqiu,Fuliu and Taixi acupoints on the lower limbs for 2 weeks can effectively improve the maximum muscle strength,endurance and work efficiency of the posterior calf muscles in healthy young men.

Diabetic kidney disease(DKD)with increasing global prevalence lacks effective therapeutic targets to halt or reverse its progression.Therapeutic targets supported by causal genetic evidence are more likely to succeed in randomized clinical trials.In this study,we integrated large-scale plasma proteomics,genetic-driven causal inference,and experimental validation to identify prioritized targets for DKD using the UK Biobank(UKB)and FinnGen cohorts.Among 2844 diabetic patients(528 with DKD),we identified 37 targets significantly associated with incident DKD,supported by both observational and causal evi-dence.Of these,22％(8/37)of the potential targets are currently under investigation for DKD or other diseases.Our prospective study confirmed that higher levels of three prioritized targets-insulin-like growth factor binding protein 4(IGFBP4),family with sequence similarity 3 member C(FAM3C),and prostaglandin D2 synthase(PTGDS)—were associated with a 4.35,3.51,and 3.57-fold increased likeli-hood of developing DKD,respectively.In addition,population-level protein-altering variants(PAVs)analysis and in vitro experiments cross-validated FAM3C and IGFBP4 as potential new target candidates for DKD,through the classic NLR family pyrin domain containing 3(NLRP3)-caspase-1-gasdermin D(GSDMD)apoptotic axis.Our results demonstrate that integrating omics data mining with causal inference may be a promising strategy for prioritizing therapeutic targets.

Right ventricular-pulmonary artery coupling(RVPAC)refers to the relationship between right ventricular contractility and afterload.Normal RVPAC is maintained only when right ventricular function and pulmonary vascular resistance are appropriately matched.When right ventricular contractility cannot increase to match afterload,thus resulting in right ventricular dysfunction.RVPAC plays an important role in pathophysiology and progression of many cardiovascular diseases,which is crucial for the prognosis of patients.Therefore,early and accurate evaluation of RVPAC has great significance for patient's condition assessment,clinical decision-making,risk stratification and prognosis judgment.There are many evaluation methods currently,which can be divided into invasive and non-invasive methods,among which the non-invasive methods are mainly correlated with ultrasound.This review summarizes pathological mechanism and evaluation methods of RVPAC,advantages and disadvantages of each method and application value of RVPAC in various cardiovascular diseases.
