Effect of Electroacupuncture on Spermatogenesis in Rats with Oligozoospermia of Insufficiency of Shen (Kidney) Essence Syndrome

Objective: To assess the effect of electroacupuncture(EA) on expression of cytoskeletal proteins from Sertoli cells(SCs) and spermatogenesis in rats with oligozoospermia of insufficiency of Shen(Kidney)essence syndrome(OIKES).Methods: Twenty healthy male Sprague-Dawley rats were randomly assigned to four groups using a random number table: control,tripterygium glycosides(TG) treatment,sham and EA groups(n=5 in each group).A rat model of OIKES was established by oral gavage with TG.The EA group was treated with TG and received EA at Shenshu(BL 23) and Zusanli(ST 36) acupoints for 20 min,once daily for 30 days,while the sham group received EA at identical acupoints with skin penetration without stimulation.After 30 days,the ?nal body weight and coef?cients for the testis and epididymis were calculated and sperm parameters were measured.Immunohistochemical analyses were performed to detect expression of vimentin and α-tubulin in SCs and proliferating cell nuclear antigen(PCNA) immunoreactivity in germ cells.Apoptosis in germ cells was quanti?ed by the transferase biotin-dUTP nick end labeling assay.Results: Compared with the control group,the final body weight and testis/epididymis coefficients of rats in the TG-treated group were not significantly different,but the sperm count and motility were lower(P0.05).Expressions of vimentin and α-tubulin were also signi?cantly weaker(P0.01).The PCNA immunoreactivity of germ cells was decreased(P=0.059),whereas the apoptotic index of germ cells was increased signi?cantly(P0.01).In contrast,EA at BL 23 and ST 36 acupoints signi?cantly improved the ?nal body weight as well as the sperm count,concentration and motility(P0.01 or P0.05).EA increased expression of vimentin and α-tubulin in SCs markedly,and signi?cantly enhanced PCNA immunoreactivity with decreased apoptosis in germ cells(P0.01 or P0.05).Conclusions: EA at BL 23 and ST 36 acupoints has protective effects on spermatogenesis in rats with OIKES.This effect seems to be achieved by attenuating TG-induced disruption of cytoskeletal protein in SCs.     

电针对缺血性脑卒中大鼠记忆功能及脑内突触囊泡蛋白的影响

观察电针对缺血性脑卒中大鼠记忆功能及脑内突触囊泡蛋白（synaptic vesicular protein，SYN）的影响，探讨其可能的作用机制。方法 选取90 只SD大鼠随机分为模型组、电针组、假手术组，每组各30只。线拴法制作急性大脑中动脉缺血大鼠模型。电针组取“百会”“水沟”“内关”“三阴交”穴位，应用“醒脑开窍”法进行电针，每天电针30 min，连续电针6 d休1 d，7 d为一个疗程，首次电针干预在造模成功24 h后进行。模型组和假手术组不进行电针干预。大鼠分别按7、14、21 d 3个亚组进行运动及记忆功能评分，TTC染色测定脑梗死体积、Western blot检测脑内SYN的蛋白表达。结果 电针组运动功能评分较模型组显著降低（P<0.01），电针组进入隐藏区潜伏期时间较模型组显著缩短（P<0.01），电针组脑梗死率较模型组显著缩小（P<0.01），SYN的蛋白表达电针组较模型组明显增强（P<0.01）。假手术组无神经功能缺损及脑梗死灶，SYN表达最弱。结论 电针干预能减小脑梗死体积，上调脑内SYN的表达，进而促进缺血性脑卒中大鼠的记忆及运动等神经功能的恢复。     

中医治疗椎动脉型颈椎病研究进展

中医治疗椎动脉型颈椎病(cervical spondylosis of vertebral artery type,CSA)的主要方法有针灸治疗、中药治疗、手法治疗、综合疗法治疗等,其中针灸治疗包括电针治疗、其他针具治疗、灸法治疗;中药治疗包括中药内服治疗与中药外用治疗;手法治疗是采用不同推拿手法改善颈部肌肉紧张状态;综合疗法为电针、推拿、艾灸、中药熏蒸等相结合,为目前临床应用较多的治疗方法。目前,中医治疗CSA仍存在一些问题,比如研究样本量较小、无高质量、多中心随机对照研究,对照组设计欠科学、观察指标简单、无远期疗效观察等;大部分研究手法及中药治疗缺乏安全性、规范性探讨。因此未来临床研究本病应扩大样本量,采取多中心、随机对照模式,细化研究指标,并将安全性、规范性纳入研究范围,制定手法量学标准,为CAS的实际推广治疗本病方法提供依据。     

Complete Recovery Following Electroacupuncture Therapy in Refractory Unilateral Sensorineural Hearing Loss

Role of electroacupuncture (EA) in refractory unilateral sensorineural hearing loss (SNHL) remains unclear but might be promising for the Meniere's disease. Two cases of unilateral SNHL who were unresponsive to conventional treatment of sudden SNHL showed complete recovery after receiving EA therapy. The first case was a 46-year-old woman who received EA in the seventh month after the acute onset of sudden right hearing loss and tinnitus. She had mild-to-moderate degree of SNHL at high frequencies in the right ear with episodic vertigo. The second case was a 55-year-old woman who received EA in the sixth year after developing sudden SNHL in the right ear. Before the EA began, her pure tone average of the affected ear was 45 dB and the phonetically balanced score was 88%. The regimen for both patients included 12 sessions of EA over four weeks at the main acupoints (Tinggong (SI 19), Ermen (TE 21), Qimai (TE 18) and Yifeng (TE 17) on the affected ear and the adjuvant acupoints (Zhongzhu (TE 3), Hegu (LI 4), Qihai (CV 6), Guanyuan (CV 4), Taixi (KI 3), and Taichong (LIV 3)). Both patients regained their normal hearing thresholds three weeks after the first EA. No adverse events were observed. Hence, EA may be a useful additional therapy in unilateral SNHL, even at the late phase when other treatments have failed because the possibility of Meniere's disease cannot be excluded.
