Objective To observe the therapeutic effect of electroacupuncture (EA) on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training for poststroke lower limb dysfunction. Methods Fifty-two qualified mild hemiplegia cases were randomized into control group A ( N=17) , control group B (N=17), and observation group (N=18 ). Control group A was given conventional rehabilitation training, control group B was given conventional rehabilitation training and task-targeting knee strength-coordination isokinetic muscle strength training based on visual feedback, and observation group was given EA on acupoints located along anterior and posterior thigh muscles plus the treatment for control group B. The treatment for the three groups was performed once a day, five days a week, lasting 3 weeks. Before and after treatment, the lower limb motor function, peak torque ( PT) of knee flexion and extension muscles, and gait speed and gait symmetry were monitored. Results After treatment for 3 weeks, the lower limb motor function, PT and gait symmetry were much improved in the three groups (P<0.05 compared with those before treatment) . Except that the gait speed and lower limb muscle tension of observation group did not differ from those of control group B ( P>0.05) , the improvement of observation indexes of control group B was superior to that of control group A, and the improvement of observation indexes of observation group was more obvious than that of the two control groups ( P<0.05) . Conclusion EA on acupoints located along anterior and posterior thigh muscles plus isokinetic muscle strength training is more effective for improving lower limb motor function of poststroke lower limb dysfunction patients than conventional isokinetic training.

AIM: To investigate the bio-effects of salusins on rat heart and cardiomyocytes. METHODS: The cardiac function was determined by multipurpose polygraph in isolated rat heart treated with various concentrations of salusin-? or salusin-?. [ 45Ca 2+] and [3H]-Leu incorporation were determined in cultured neonatal rat cardiomyocytes with ?-liquid scintillation counter. RESULTS: 10 -12-10 -7mol/L salusin-? and salusin-? had no effects on isolated rat cardiac function. However, salusin-? and salusin-? stimulated [ 45Ca 2+] uptake and [3H]-Leu incorporation. The [ 45Ca 2+] uptake induced by salusins were inhibited by nicardipine, and were synergistically increased by endothelin-1. The [3H]-Leu incorporation induced by salusin-? and salusin-? was inhibited by nicardipine, FK506 (a special inhibitor of carcineulin), PD 98059 (inhibitor of MAPK) and chelerthine (inhibitor of PKC). The effects of salusin-? on [ 45Ca 2+] uptake was stronger than those of salusin-?. But there were no statistical difference in [3H]-Leu incorporation between salusin-? and salusin-?. CONCLUSIONS: Salusin-? and salusin-? did not affect directly cardiac function in rat hearts. But salusins improved calcium uptake and protein synthesize in neonatal rat cardiomyocytes. Those effects of salusins were related with calcium channel, carcinuelin, MAPK and PKC signal pathways. Salusins may be the regulatory factors for myocardium growth and hypertrophy.

ObjectiveTo investigate the comorbidity of community patients with stroke in Songjiang District， Shanghai， determine the prevalence and characteristics of comorbidities and influencing factors， and provide scientific evidence for prevention and treatment of stroke. MethodsA natural population-based cohort study was conducted in several communities of Songjiang District from April 2016 to October 2017. Questionnaire survey， physical examination and biochemical examination were conducted in the cohort population to understand the comorbidity of 1 523 patients with stroke at baseline. ResultsThe prevalence of comorbidities in community patients with stroke was 74.0%， which was higher in female （76.36%） than that in male （70.76%）. The average number of comorbidities was 2.62±1.56， which was significantly higher in female （2.70±1.58） than that in male （2.52±1.54） （t=-2.31， P=0.021）. In this population， the most common two-comorbidity combination was hypertension+central obesity （35.85%）， and the most common three-comorbidity combination was hypertension+dyslipidemia+central obesity （17.20%）， with statistically significant differences by gender and age groups （P<0.05）. Multivariate analysis showed that age ≥65 years， urban population， hyperhomocysteinemia （HHcy）， and family history of hypertension were risk factors associated with comorbidities， whereas educational level of middle school and high school， and physical exercise 1‒3 days per week were protective factors. ConclusionPrevalence of comorbidity is high in community patients with stroke in Songjiang District， Shanghai. It is suggested to control blood pressure and body weight， adopt healthy lifestyle and take comprehensive prevention and treatment measures in this population.

【Objective】 To explore the efficacy of transurethral columnar balloon dilation of prostate (TUCBDP) and transurethral bipolar plasmakinetic resection of prostate (TUPKP) for patients with small volume (≤30 mL) benign prostatic hyperplasia (BPH) and the effects on urinary control and sexual function. 【Methods】 Clinical data of BPH patients who underwent surgical treatment during Jun.2021 and Jan.2022 were reviewed. A total of 95 patients with prostate volume ≤30 mL and regular sexual life were selected as subjects, including 45 patients who received TUCBDP as the TUCBDP group and 50 patients who received TUPKP as the TUPKP group. The patients were followed up for 12 months, and the perioperative data and follow-up results were analyzed. 【Results】 The TUCBDP group had shorter operation time, less intraoperative blood loss, less postoperative hemoglobin loss and sodium concentration loss, shorter bladder irrigation time, lower pain score, shorter urinary tube indwelling time and shorter hospital stay than the TUPKP group (P<0.05). Twelve months after surgery, the International Prostate Symptom score (IPSS), quality of life score (QoL), residual urine volume (PVR) and maximum urine flow rate (Qmax) were significantly improved in both groups (P<0.05). The International Index of Erectile Function-5 (IIEF-5), Erection Hardness Grading Score (EHS), Sexual Function Score in Patients with Premature Ejaculation-5 (CIPE-5) score had no significant differences compared with those before surgery (P>0.05). The TUPKP group had worse ejaculation function score and ejaculation disturbance score after surgery (P<0.05), while the TUCBDP group had no significant change (P>0.05), and the two indexes were superior in the TUCBDP group than in the TUPKP group. The TUCBDP group had significantly lower complication rate than the TUPKP group (P<0.05). 【Conclusion】 TUCBDP is safe and effective in the treatment of small volume (≤30 mL) BPH, less trauma, less biochemical interference, less pain, fewer complications, and shorter course of disease. It has little effect on the ejaculation function and erectile function, and is more suitable for patients requiring retention of sexual function. It has a good application prospect in the treatment of small volume BPH.
