Meta-analysis of the efficacy of acupuncture in the treatment of the vascular cognitive impairment associated with cerebral small vessel disease

ObjectiveTo systematically evaluate the efficacy and safety of acupuncture in the treatment of the vascular cognitive impairment (VCI) associated with cerebral small vessel disease (CSVD–VCI) and to provide a theoretical basis for clinical acupuncture treatment for CSVD–VCI.MethodVarious databases, including China National Knowledge Infrastructure, Wanfang Data, Chinese Science and Technology Journal Database, Chinese BioMedical Literature Service System, PubMed, the Cochrane Library, and EBSCOhost, were searched for randomized controlled trials (RCTs) related to acupuncture treatment for CSVD–VCI. The quality of the included trials was evaluated, and a meta-analysis was conducted using the Review Manager 5.4 software.ResultsTen articles on RCTs were included, involving 761 patients, i.e., 381 in the acupuncture group and 380 in the control group. The meta-analysis results indicated that the use of acupuncture alone and acupuncture alongside other therapies for CSVD–VCI could improve the overall clinical response rate [odds ratio = 3.51, 95% confidence interval (CI) = (2.05, 6.00), P < 0.00001], increase the patients’ Montreal Cognitive Assessment scores [mean difference (MD) = 3.33, 95%CI (2.98, 3.68), P < 0.00001], Mini-Mental State Examination scores [MD = 2.78, 95%CI (2.51, 3.06), P < 0.00001], and activities of daily living scores [MD = 6.30, 95%CI (4.22, 8.37), P < 0.00001], and shorten the latency of auditory evoked potential P300 [MD = −14.67, 95%CI (−19.54, −9.80), P < 0.00001].ConclusionAcupuncture alone and acupuncture alongside other therapies are superior to non-acupuncture-based therapies in the treatment of CSVD–VCI. However, due to the small number of relevant available articles and their general low quality, this conclusion may be biased. More clinical RCTs with a larger sample size and higher quality are needed to support this theory.

肠泻停胶囊止泻作用研究

目的 观察肠泻停胶囊的止泻作用。方法 采用新斯的明负荷肠推进亢进以及番泻叶、蓖麻油诱导的腹泻模型，通过测定肠推进百分率、腹泻潜伏期以及腹泻次数等指标来评价肠泻停胶囊的止泻作用，通过离体豚鼠回肠试验，观察其可能的作用机制。结果 肠泻停胶囊明显降低正常小鼠以及新斯的明负荷小鼠的小肠推进百分率；对口服番泻叶浸荆或蓖麻油所致的腹泻模型小鼠均有明显的保护作用；对豚鼠离体回肠的收缩幅度和张力有明显的抑制作用。结论 肠泻停胶囊具有明显的止泻作用。

杀菌剂十三吗啉的致突变性

目的研究杀菌剂十三吗啉原药的致突变性。方法小鼠骨髓多染红细胞微核试验剂量设为150、3006、00 mg/kg;小鼠睾丸精母细胞染色体畸变试验剂量设为163、326、652 mg/kg。Ames试验剂量设为5、50、500、1 000、5 000μg/皿。结果小鼠骨髓多染红细胞微核试验和小鼠睾丸精母细胞染色体畸变试验,各剂量组和阴性对照组比较,差异无显著意义(P>0.05);Ames试验中各测试浓度的回变菌落数均末超过自然回变菌落数的2倍。结论该试验范围内,未见十三吗啉原药有致突变性。     

dl-四氢巴马汀抗大鼠胃溃疡作用

 目的研究dl-四氢巴马汀(dl-THP)对大鼠急、慢性溃疡的保护作用,并初步分析其机制。方法胃黏膜损伤由吲哚美辛、束缚应激、结扎幽门和胃浆膜下注入醋酸引起。dl-THP15,30,45mg·kg^-1灌胃,1日2次,共5次。测定大鼠胃溃疡数目、面积、胃酸分泌、胃蛋白酶活性以及胃黏膜血流。结果dl-THP15,30,45mg·kg^-1能抑制大鼠胃黏膜损伤,且呈剂量依赖性;dl-THP30mg·kg^-1对大鼠慢性胃溃疡的抑制率为75.8%,与雷尼替丁30mg·kg^-1的67.7%相仿。dl-THP可增加胃黏膜血流,但对胃酸和胃蛋白酶分泌无影响。结论dl-THP具有明显抗实验性胃溃疡作用,可能与其增加胃黏膜血流有关,亦可能部分通过阻滞胃黏膜DA受体而发挥作用。
