[Acupuncture for chronic prostatitis/chronic pelvic pain syndrome: a randomized controlled trial].

OBJECTIVE: To observe the short-term efficacy, long-term efficacy and safety of acupuncture for chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). METHODS: Forty-two patients with CP/CPPS were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases). The patients in the acupuncture group were treated with acupuncture at bilateral Zhongliao (BL 33), Huiyang (BL 35), Shenshu (BL 23) and Sanyinjiao (SP 6); the needling depth of Zhongliao (BL 33) and Huiyang (BL 35) was 60 to 80 mm, while Shenshu (BL 23) and Sanyinjiao (SP 6) was directly punctured of 30 mm. The patients in the sham acupuncture group were treated with acupuncture at non-acupoints, including points 2 cm next to Shenshu (BL 23), Zhongliao (BL 33) and Huiyang (BL 35), and the midpoint of the connecting line between the spleen meridian and the kidney meridian. All the non-acupoints were treated with directly puncture of 2 to 3 mm. The needles were left for 30 min in both groups, once every other day in the first four weeks, three times a week, and twice a week in the next four weeks, totally 20 treatments. Before treatment, after treatment and in follow-up of 24 weeks after treatment completion, the National Institutes of Health-chronic prostatitis symptom index (NIH-CPSI) score and urinary flow rate were observed in both groups; the clinical efficacy and safety were evaluated. RESULTS: Compared with those before treatment, the pain and discomfort scores, urination symptoms scores, quality of life scores and total scores of NIH-CPSI in both groups were reduced after treatment in the two groups (P<0.01), while each item score and total score of NIH-CPSI in the acupuncture group were reduced in follow-up (P<0.01, P<0.05). After treatment and in follow-up, each item score and total score of NIH-CPSI in the acupuncture group were lower than those in the sham acupuncture group (P<0.05, P<0.01). After treatment, the maximum and average urinary flow rates in the acupuncture group were higher than those before treatment (P<0.05), and the average urinary flow rate in the acupuncture group was higher than that in the sham acupuncture group (P<0.05). The total effective rate was 75.0% (15/20) in the acupuncture group, which was higher than 42.9% (9/21) in the sham acupuncture group (P<0.05). No significant adverse reactions were observed in the two groups, and there was no significant difference in the incidence of adverse reactions between the two groups (P>0.05). CONCLUSION: Acupuncture could effectively alleviate the clinical symptoms, improve quality of life, and has a sustained, safe and reliable therapeutic effect in patients with CP/CPPS.

Pubescenosides Q-R, two new phenolic glycosides from Ilex pubescens.

Two new phenolic glycosides (1-2), along with six existing compounds (3-8), were isolated from the ethanolic extract of Ilex pubescens roots, a traditional folk medicine. These structures were determined using HR-ESI-MS, IR, UV, and NMR (including 1 D, 2 D-NMR). The anti-inflammatory activities of three phenolic glycosides (1-3) were evaluated in the human HepG2 cell lines. The results showed that compound 3 could induce P-gp and BCRP expression through the Nrf2-mediated pathway.[Formula: see text].

[Effect of electronic moxibustion on memory function in patients with amnestic mild cognitive impairment].

OBJECTIVE: To observe the effect of electronic moxibustion on memory function in the patients with amnestic mild cognitive impairment (aMCI). METHODS: A total of 59 aMCI patients were randomized into an electronic moxibustion group (30 cases) and a placebo moxibustion group (29 cases). In the electronic moxibustion group, the electronic moxibustion was applied to Baihui (GV 20), Dazhui (GV 14), Mingmen (GV 4) and Taixi (KI 3), 45 ℃ in temperature, 20 min each time. The treatment was given once a day, 5 times a week. The treatment for 4 weeks was as one course and 2 courses were required totally. In the placebo moxibustion group, the moxa-free patch was used, 38 ℃ in temperature. The acupoint selection and the treatment frequency were same as the electronic moxibustion group. Before and after treatment, Rivermead behavior memory test (RBMT) was adopted to evaluate the global memory function of the patients in the two groups and the N-back task test was adopted to evaluate working memory function separately. Additionally, the mini-mental state examination (MMSE) and its immediate memory, Montreal cognitive assessment (MoCA) and its delay recall were adopted to evaluate the global cognitive function and memory function. RESULTS: In the electronic moxibustion group, after treatment, RBMT score, N-back accuracy rates, MMSE and MoCA scores and the scores of immediate memory and delay recall were improved significantly as compared with those before treatment (P<0.01). In the placebo moxibustion group, the accuracy rates of 1-back and 2-back task and the scores of immediate memory and delay recall were improved obviously as compared with those before treatment (P<0.05, P<0.01). After treatment, the improvements of RBMT score, the accuracy rates of N-back task and MMSE and MoCA scores in the electronic moxibustion group were higher than those in the placebo moxibustion group (P<0.05). CONCLUSION: Electronic moxibustion improves memory function in the patients with amnestic mild cognitive impairment.

Comparative analysis of robotic vs laparoscopic radical hysterectomy for cervical cancer.

BACKGROUND: Cervical cancer is the most common gynecological malignancy, ranking first in female reproductive malignancies with more than 500000 new cases and 275000 deaths each year. Traditionally, open radical hysterectomy is considered the standard surgical procedure for the treatment of resectable cervical cancer. The latest guidelines from the National Comprehensive Cancer Network and the European Society of Gynecological Oncology suggest that open surgery and laparoscopic surgery (using traditional laparoscopic or robotic techniques) are the main surgical approaches for radical hysterectomy for patients with stage IA2-IIA cervical cancer. Robotic surgery has been increasingly used in abdominal surgery and has shown more beneficial effects. AIM: To analyse the perioperative conditions, complications, and short-term and long-term effects in patients undergoing robotic radical hysterectomy (RRH) and laparoscopic radical hysterectomy (LRH) to compare their clinical efficacy, safety, and feasibility. METHODS: The perioperative data of patients undergoing RRH and LRH were extracted and collected from the database of surgical treatments for cervical cancer for statistical analysis. RESULTS: Of the patients, 342 underwent LRH for cervical cancer, and 216 underwent RRH. The total complication rate was 9.65% (20 patients) in the RRH group and 17.59% (60 patients) in the LRH group. The complication rate was significantly lower in the RRH group than in the LRH group. There was no significant difference in the follow-up period (P = 0.658). The total recurrence rates were 15.7% and 12% in the RRH and LRH groups, respectively. The progression-free survival time was 28.91 ± 15.68 mo and 28.34 ± 15.13 mo in the RRH and LRH groups, respectively (P = 0.669). The overall survival (OS) rates were 92.13% and 94.45% in the RRH and LRH groups, respectively (P = 0.292). The OS time was 29.87 ± 15.92 mo and 29.41 ± 15.14 mo in the RRH and LRH groups, respectively (P = 0.732). The survival curves and the progression-free survival curves were not statistically significantly different between the two groups (P = 0.407 and 0.28, respectively). CONCLUSION: RRH is associated with significantly less operative time and blood loss than LRH. The two procedures have similar complication rates, OS, and progression-free survival time.

Protective effects of l-arginine against testosterone synthesis decreased by T-2 toxin in mouse Leydig cells.

The testosterone levels decreased by T-2 toxin in mouse Leydig cells were reported previously. It is not known, however, whether l-arginine improves the situation and what's the mechanism. Leydig cells were isolated and cultured with control, 10 nM T-2 toxin, 0.25, 0.5 or 1.0 mM l-arginine, and 10 nM T-2 toxin supplemented with 0.25, 0.5 or 1.0 mM l-arginine for 24 h. Cells and supernatants were collected to detect the mRNA expression and activities of P450scc (cholesterol side-chain cleavage enzyme), 3ß-HSD-1 (3ß-hydroxysteroid dehydrogenase/isomerase-1) and StAR (steroidogenic acute regulatory protein). Results revealed that l-arginine increased the testosterone levels declined by T-2 toxin and up-regulated the activities and mRNA expression of P450scc, 3ß-HSD-1 and StAR down-regulated by T-2 toxin in Leydig cells. Therefore, we concluded that l-arginine ameliorated the testosterone levels decreased by T-2 Toxin via regulating the mRNA expression and activities of P450scc, 3ß-HSD-1 and StAR in mouse Leydig cells.

A retrospective study of acupuncture as an adjunctive therapy to topical ibuprofen for chronic knee pain due to osteoarthritis.

This retrospective study investigated the effectiveness and safety of acupuncture as an adjunctive therapy to topical ibuprofen (TIP) for patients with chronic knee pain (CKP) due to osteoarthritis.This retrospective study analyzed medical records of 84 patients with CKP due to osteoarthritis. These patients were divided into a treatment group (n = 42) and a control group (n = 42). The patients in the treatment group were treated with acupuncture plus TIP, while the subjects in the control group received TIP monotherapy. The primary effectiveness endpoint was assessed by Western Ontario and McMaster Universities osteoarthritis index (WOMAC). The secondary effectiveness endpoints were evaluated by the numeric rating scale (NRS), 12-item Short FormHealth Survey (SF-12, mainly including mental component summary [MCS], and physical component summary [PCS]), and adverse events. All patients received an 8-week treatment. All endpoints were measured pre-treatment and posttreatment.The patients who received acupuncture plus TIP showed better effectiveness in both primary endpoint of WOMAC scale (pain, P < .01; function, P < .01; and stiffness, P < .01) and secondary endpoints of NRS (P < .01), and SF-12 (MCS, P < .01; and PCS, P < .01), than patients who received TIP monotherapy. In addition, both groups had similar safety profile.The results of this study showed that the effectiveness of acupuncture plus TIP may be better than TIP monotherapy for patients with CKP due to osteoarthritis.

[Professor ZHANG Qing-ping's experience in the treatment of vascular dementia with acupuncture and moxibustion].

In the aspects of the acupoint prescription, acupuncture techniques and typical cases, the characteristics and experience of professor ZHANG Qing-ping in the clinical treatment of vascular dementia with acupuncture and moxibustion were introduced. Vascular dementia is treated on the base of etiology, focusing on the brain as the root cause, with the reinforcing and the promoting as the dominant principle of acupuncture. The treatment is emphasized on tonifying the kidney to fill up marrow, strengthening the spleen to nourish the brain and promoting the collateral circulation to improve the intelligence. Concerning to the general situation of the disease, regulating mind stressed in treatment. In clinical practice, Baihui (GV 20) is the chief acupoint to benefit the brain. Yuan-source points and the eight influential points are predominated to tonify the functions of zangfu organs and fill up vessels. Moxibustion is adopted to resolve the stagnation and promote circulation in meridian as well as regulate qi and blood circulation. Specially, the moxibustion technique for resolving the stagnation and promoting circulation in meridian achieves the satisfactory therapeutic effects in clinical treatment.

Effectiveness of neuromuscular electrical stimulation and ibuprofen for pain caused by necrosis of the femoral head: A retrospective study.

This retrospective study analyzed the effectiveness of neuromuscular electrical stimulation (NMES) for pain relief caused by necrosis of femoral head (NFH).Totally, 80 cases of patients with NFH were analyzed and then were assigned to a treatment group or a control group in this study. Of these, 40 cases in the treatment group received ibuprofen and NMES therapy. The other 40 cases in the control group received ibuprofen alone. Cases in both groups were treated for a total of 6 weeks. The primary outcome of pain intensity was measured by a visual analog scale (VAS). The secondary outcome was assessed by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). In addition, adverse events (AEs) were also recorded in each case. All outcomes were evaluated before and after the treatment.After treatment, patients in the treatment group showed more effectiveness in pain relief, as measured by VAS (P < .01) and WOMAC sub-pain scale (P < .01), except stiffness, as evaluated by WOMAC sub-stiffness scale (P = .07), and function, as assessed by WOMAC sub-function scale (P = .09), than patients in the control group. Additionally, no significant differences in AEs were detected between 2 groups.This study found that NMES may be helpful for pain relief in patients with NFH.

l-arginine protects against T-2 toxin-induced male reproductive impairments in mice.

l-arginine is beneficial for reproductive health; however, whether l-arginine may confer protection against T-2 toxin-induced reproductive impairment is not known. To address this, we used a mice model treated with T-2 toxin to investigate protective effects of l-arginine. Experimentally, we pre-treated mice with designed diet of l-arginine supplementation prior to the T-2 toxin-injected intraperitoneally exposure and then assessed semen quality, fertility and serum testosterone concentration. The results showed that l-arginine improved semen quality (e.g., live spermatozoa, abnormal spermatozoa, and acrosomal integrity of spermatozoa), testicular and cauda epididymal sperm counts, efficiency of sperm production and serum testosterone concentration in mice treated with T-2 toxin. In addition, l-arginine could increase pregnancy rate and decrease fetal resorption rate in females mated with T-2 toxin exposed males. Collectively, these findings suggest that dietary l-arginine supplementation may protect male reproductive impairments in mice treated with T-2 toxin through improving semen quality and serum testosterone levels.

Role of early environmental enrichment on the social dominance tube test at adulthood in the rat.

RATIONALE: Environmental enrichment (EE) could influence brain plasticity and behavior in rodents. Whether the early EE may predispose individuals to a particular social hierarchy in the social dominance tube test (SDTT) at adulthood is still unknown. OBJECTIVE: The present study directly investigated the influence of EE on competitive success in the SDTT among adult rats. METHODS: Male rats were maintained in EE from postnatal days 21 to 35. Social dominance behavior was determined by SDTT, competitive food foraging test, and mate preference test at adulthood. IBA-1 expression in the hypothalamus was examined using immunohistochemistry and western blot. RESULTS: EE rats were prone to become submissive during a social encounter with standard environment (SE) rats in the SDTT. No difference was found in food foraging in the competitive food foraging test between SE and EE rats. Male EE rats were more attractive than the SE to the female rats in the mate preference test. IBA-1 expression was found to be decreased in the hypothalamus of EE rats compared to SE group. Infusion of a microglia inhibitor reduced percentage of forward in SE rats in the SDTT. Infusion of DNA methyltransferase inhibitor prevented the development of subordinate status in EE rats and restored the expression of IBA-1 in the hypothalamus. CONCLUSIONS: The results suggest that early EE did not lead to reduced social hierarchy in the male rat. However, EE caused a reduction in the percentage of forward in the SDTT, which might be associated with reduced number of microglia in the hypothalamus.

In situ investigation to three dimensional structures of Chinese medicines seeds / 中国中药杂志

This paper is aimed to microscopic identification of traditional Chinese medicines (TCMs) using an in situ imaging method. In this study, two kinds of Zingiberaceae seeds, Amomi Rotundus Fructus and Alpiniae Katsumadai Semen, were investigated by synchrotron radiation in-line X-ray phase-contrast computed tomography (IXPCT) imaging method. The results showed that the microstructures of these Zingiberaceae seeds could be clearly obtained from the virtual slices information in different observing angles. It proves that IXPCT is an effective imaging method, which can provide the imaging information for the microscopic identification of the intact TCMs in situ and non-destructively.
