Objective:To observe the clinical effect of electrophysiological technique in treating chronic prostatitis.Meth-ods:Choose 40 patients of chronic prostatitis/chronic pelvic pain syndrome(chronicprostatis/chronicpelvicpainsyndrome,CP/CPPS)in People's Hospital in Zhijin and People's hospital in Guizhou Province from January 2022 to April 2023,The patients were randomly divided into control group(n=20)and treatment group(n=20).The treatment group received low-frequency neuromuscular electri-cal stimulation combined with drug therapy,while the control group received drug therapy alone.The improvement of prostatitis symp-tom score(NIH-CPSI)and International Prostatitis Symptom score(IPSS)before and after treatment was compared and analyzed.Results:A total of 37 patients were followed up(1 patient in the treatment group withdrew due to hypersensitivity to the electrode;2 patients in the control group were lost to follow-up.)There was no significant difference in baseline data between the two groups(P>0.05).The NIH-CPSI score and IPSS score before and after treatment were compared between the two groups,and the difference was statistically significant(P<0.05).The IPSS score of the two groups after treatment was compared,the average reduction of the treat-ment group was15.84±0.92 points,and that of the control group was7.17±0.40 points,and the difference was statistically signifi-cant(t=4.792,P<0.05).The NIH-CPSI score of the two groups after treatment was compared,and the average reduction was 17.47±0.92 points in the treatment group and 10.56±0.49 points in the control group.The difference between the two groups was statistically significant(t=6.654,P<0.05).Conclusion:The effect of electrophysiological combined drug therapy is obviously better than that of simple drug therapy.Electrophysiological therapy for chronic prostatitis has definite clinical effect and is worth pro-moting and applying.

Objective: To investigate the association between the urinary arsenic level and serum total testosterone in Chinese men aged 18 to 79 years. Methods: A total of 5 048 male participants aged 18 to 79 years were recruited from the China National Human Biomonitoring (CNHBM) from 2017 to 2018. Questionnaires and physical examinations were used to collect information on demographic characteristics, lifestyle, food intake frequency and health status. Venous blood and urine samples were collected to detect the level of serum total testosterone, urinary arsenic and urinary creatinine. Participants were divided into three groups (low, middle, and high) based on the tertiles of creatinine-adjusted urinary arsenic concentration. Weighted multiple linear regression was fitted to analyze the association of urinary arsenic with serum total testosterone. Results: The weighted average age of 5 048 Chinese men was (46.72±0.40) years. Geometric mean concentration (95%CI) of urinary arsenic, creatinine-adjusted urinary arsenic and serum testosterone was 22.46 (20.08, 25.12) μg/L, 19.36 (16.92, 22.15) μg/g·Cr and 18.13 (17.42, 18.85) nmol/L, respectively. After controlling for covariates, compared with the low-level urinary arsenic group, the testosterone level of the participants in the middle-level group and the high-level group decreased gradually. The percentile ratio (95%CI) was -5.17% (-13.14%, 3.54%) and -10.33% (-15.68%, -4.63). The subgroup analysis showed that the association between the urinary arsenic level and testosterone level was more obvious in the group with BMI<24 kg/m² group (P_interaction=0.023). Conclusion: There is a negative association between the urinary arsenic level and serum total testosterone in Chinese men aged 18 to 79 years.

Objective: To verify effects of rs1061622 at tumor necrosis factor-α receptor II (TNF-RII) gene (TNF-RII) on post-traumatic stress disorder (PTSD) and its interactive effects with PTSD on serum lipids levels in adolescents. Methods: PTSD was measured by PTSD Checklist-Civilian Version (PCL-C) in 699 adolescent survivors at 6 months after Wenchuan earthquake in China. A polymerase chain reaction and restriction fragment length polymorphism assay were utilized for TNF-RII rs1061622 genotyping followed by verification using DNA sequencing. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol were tested using routine methods. Results: G (deoxyguanine) allele carriers had higher PCL-C scores than TT (deoxythymidine) homozygotes in female subjects. Female adolescents had higher PCL-C scores than male subjects in TT homozygotes. Predictors of PTSD prevalence and severity were different between G allele carriers and TT homozygotes. Subjects with PTSD had lower TG, TG/HDL-C, TC/HDL-C, and higher HDL-C than adolescents without PTSD in male G allele carriers. G allele carriers had higher TG/HDL-C and TC/HDL-C than TT homozygotes in male adolescents without PTSD, and lower TG and TG/HDL-C in male PTSD patients. G allele carriers had higher TG than TT homozygotes only in female adolescents without PTSD. Conclusion These results suggest reciprocal actions of TNF-RII rs1061622 with other factors on PTSD severity, interplays of TNF-RII rs1061622 with PTSD on serum lipid levels, and novel treatment strategies for PTSD and comorbidities of PTSD with hyperlipidemia among adolescents with different genetic backgrounds of TNF-RII rs1061622 after experiencing traumatic events.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

OBJECTIVE: To explore the characteristics and rules of acupoint sensitization phenomena based on knee osteoarthritis (KOA), one of the clinical dominant diseases of acupuncture-moxibustion. METHODS: In combination with literature and expert experiences, the acupoints with the highest use frequency in treatment of KOA were screened, e.g. Heding (EX-LE 2), Liangqiu (ST 34), Mingmen (GV 4), Neixiyan (EX-LE 4), Ququan (LR 8) and Dubi (ST 35). In 814 patients with KOA and 217 healthy subjects, the acupoint temperature, mechanic pain threshold and pressure pain threshold were detected separately. Using machine learning method, the sensitization was judged at each acupoint. RESULTS: Compared with healthy subjects, the acupoint temperature was increased and the mechanic pain threshold and pressure pain threshold were reduced in KOA patients (P<0.05). Besides, the cut-off value was presented to distinguish whether the acupoint was sensitized or not. The results of machine learning showed that the highest prediction accuracy of acupoint sensitization was 86.7% (Shenshu [BL 23]) and the lowest one was 73.9% (Heding [EX LE 2]). The prediction accuracy at the third clinical stage trial was higher, the highest was 93.3% (Ququan [LR 8]) in KOA patients. CONCLUSION It is confirmed that the acupoint sensitization reflects the characteristics of disease and is correlative with the conditions of illness, which may provide the reference for the auxiliary diagnosis and condition assessment of KOA.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Objective:To analyze the risk factors for early neurological deterioration(END)in elderly patients with acute ischemic stroke(AIS)after intravenous thrombolysis.Methods:Clinical data of 118 patients with AIS who had received thrombolysis were collected retrospectively.According to the occurrence of END, cases were divided into the END group(n=28)and the non-END group(n=90). Univariate analysis was used to compare general characteristics, clinical data, laboratory test results, TOAST classification, infarct location, and degree of culprit vessel stenosis between the two groups.Multivariate Logistic regression analysis was used to analyze the related factors for END.Results:Univariate analysis showed that the proportion of patients with diabetes mellitus and previous cerebral infarction was higher in the END group than in the non-END group( χ2=4.000 and 8.056, P=0.046 and 0.005). There were significant differences in National Institutes of Health Stroke Scale(NIHSS)score, time from onset to thrombolysis, thrombolysis time, swallowing dysfunction, albumin, leukocyte count, neutrophil count, lymphocyte count, glycosylated hemoglobin(HbA1c), creatinine, total cholesterol(TC), low density lipoprotein cholesterol(LDL-C), high density lipoprotein cholesterol(HDL-C)and lipoprotein(a)levels between the two groups(all P<0.05). There were also significant differences between the two groups in TOAST classification, infarct location and degree of culprit vessel stenosis( χ2=13.109 and 9.509, Z=2.912, P=0.004, 0.023 and 0.004). Multivariate Logistic regression analysis showed that NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vessel stenosis and leukocyte count on admission were independent risk factors for END( OR=1.122, 2.131, 1.965, 1.876 and 1.563, P=0.036, 0.024, 0.028, 0.030 and 0.041). Conclusions:NIHSS score, HbA1c, cardiogenic stroke, degree of culprit vascular stenosis and leukocyte count on admission are independent risk factors for END, which should be closely monitored and managed with well formulated preventive measures in order to improve the prognosis of AIS patients.

Objective:To assess the efficacy and safety of cinepazide maleate injection in the treatment of patients with acute ischemic stroke.Methods:A multicenter, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial, led by Peking Union Medical College Hospital, was conducted in 65 Hospitals in China. The efficacy of cinepazide maleate injection in patients with acute anterior circulation cerebral infarction with onset time of ≤48 hours, 7≤National Institute of Health stroke scale (NIHSS) score ≤25 was assessed from August 2016 to February 2019, using the proportion of modified Rankin scale (mRS) score≤1 and Barthel index (BI) score≤95 on day 14 as efficacy endpoint. The patients were divided into treatment group who were treated with cinepazide maleate injection and control group who were treated with placebo.Results:A total 937 patients were involved in the final efficacy analysis (466 in treatment group and 471 in control group). The proportion of subjects with mRS score≤1 on day 14 after treatment were higher in the treatment group than that in the control group (102/466(21.89%) vs76/471(16.14%)). Logistic regression analysis showed that patients treated with cinepazide maleate were significantly more likely to have a favorable outcome (mRS score≤1) than patients treated with placebo on day 14 ( OR=0.677, 95% CI 0.484-0.948 , P=0.023), and patients treated with cinepazide maleate were more likely to reach independence in activities of daily living (Barthel Index ≥95) than those treated with placebo on day 14 (125/466(26.82%) vs 91/471(19.32%); OR=0.632, 95% CI0.459-0.869, P=0.005). The rate of adverse events was similar between the treatment and control groups. Conclusion:The 14-day treatment with cinepazide maleate injection could reduce the degree of disability whereas did not increase the risk of adverse events.
