Background/Purpose

Nemonoxacin is a novel nonfluorinated quinolone with excellent in vitro activity against most pathogens in community-acquired pneumonia (CAP), especially Gram-positive isolates. The purpose of this study was to assess the efficacy and safety of nemonoxacin compared with levofloxacin in patients with CAP.

Penetration moxibustion for postpartum subinvolution of uterus: Two case reports and mechanism analysis: 透灸法成功治疗产后子宫复旧不良:两则病例报告及机制分析

This article introduced the application of penetration moxibustion in successfully treating two cases of postpartum subinvolution of uterus. The main complaint of one case was increasing volume of abnormal vaginal bleeding for five days after delivery. The bleeding stopped after the patient received 7 times treatment of warming needle and penetration moxibustion on Zhōngjí (中极CV3), Guānyuán (关元CV4) and Qìhăi (气海CV6). The other case complained about persistent abdominal pain for 15 days, which was worsening for the recent 2 days. The symptom of abdominal pain was relieved after the penetration moxibustion was applied on CV4, CV6 and Zǐgōng (子宫 EX-CA1) for 5 times for the case. Penetration moxibustion can relieve abdominal pain during the postpartum period, accelerate lochia discharge, and recovery of menstrual and uterine cavity. Àiyè (艾叶 Artemisiae Argyi Folium) was proved to have antibacterial, hemostatic, and analgesic effects. The warming function and radiation features of moxibustion can help to alleviate spasm of the smooth muscle in the uterus and enhance the metabolism of the uterine tissue by expanding microvessels and improving the circulations of both blood and lymph. It can also activate cells in the uterine tissue by increased temperature in order to enhance the decomposition and elimination of pathological wastes, such as inflammation and hematoma. In addition, it can also relieve pelvic pain by inhibiting neuronal excitability.     

当归不同有效部位对高原低氧模型小鼠免疫功能的影响

目的探讨当归不同有效部位对高原低氧模型小鼠免疫功能的干预作用。方法将SPF级小鼠采用随机数字表法分为对照组、模型组、红景天组及当归有效部位B、X、C组。灌胃给药,每日1次,连续21 d。除对照组外,第8日起各组小鼠每日灌胃30 min后于低氧舱中模拟高海拔环境进行低氧暴露。第22日出舱称重后眼球采血处死小鼠,制备脾淋巴细胞悬液。MTT法检测各组小鼠脾淋巴细胞增殖能力、转化能力及NK细胞杀伤活力。ELISA检测各组小鼠血清白细胞介素(IL)-2含量。结果与对照组比较,模型组小鼠在处死前体质量明显下降,脾淋巴细胞增殖能力、转化能力、刺激指数及NK细胞杀伤活性均明显下降,血清IL-2含量明显降低(P0.05,P0.01);与模型组比较,各给药组小鼠脾淋巴细胞增殖能力、转化能力及NK细胞杀伤活性均明显升高(P0.05,P0.01),当归有效部位X组刺激指数明显升高,当归有效部位X、C组血清IL-2含量均明显升高(P0.05,P0.01)。结论当归不同有效部位对低氧暴露下的小鼠免疫功能具有一定的增强作用。

Improving the health and treatment success rates of in vitro fertilization patients with traditional Chinese medicine: Need for more robust evidence and innovative approaches

Maximising access to and the success of fertility treatments should be a priority for global reproductive health, as should overall patient well-being. The demand for in vitro fertilization(IVF) and other assisted fertility treatments has increased over the past decade and is likely to further increase in years to come.Nevertheless, there is still considerable unmet demand for infertility support worldwide. Moreover, the high emotional, physical and financial burden experienced by individuals un...     

咳喘宁胶囊对慢性阻塞性肺疾病稳定期患者气道炎症细胞及炎性介质的影响

目的观察咳喘宁胶囊对慢性阻塞性肺疾病(COPD)稳定期患者气道炎症细胞及炎性介质的影响。方法采用随机数字表法将110例COPD稳定期患者随机分为治疗组和对照组各55例。2组均予复方异丙托溴铵溶液气雾吸入。同时,治疗组口服咳喘宁胶囊,每次4粒,每日3次;对照组口服等剂量安慰剂胶囊。疗程均为3个月。观察痰炎症细胞分类计数、血清及痰上清液中炎症因子水平。结果治疗组治疗后痰中性粒细胞下降(P0.05)、巨噬细胞增多(P0.05),与对照组比较差异有统计学意义(P0.05)。2组治疗前后血清白细胞介素(IL)-6、IL-8、白三烯B4(LTB4)水平差异无统计学意义(P0.05);治疗组治疗后痰上清液IL-6、IL-8、LTB4水平均下降(P0.05),与对照组比较差异有统计学意义(P0.05)。结论咳喘宁胶囊对稳定期COPD患者气道炎症细胞及炎性介质释放有明显的抑制作用。     

微管调控成骨细胞功能的研究进展

成骨细胞是一类具有成骨潜能的细胞,在骨稳态及骨重建的维持过程中具有重要作用,其分化过程受多种因素的调控。微管（microtubules,MT）在成骨细胞增殖、分化、矿化和自噬等生理过程中均发挥着重要作用。近年来研究发现,微管调控成骨细胞功能与微管翻译后修饰及微管相关蛋白介导的微管动态重组密切相关,但其具体机制尚未完全明了。本文拟对微管调控成骨细胞功能的研究进展作一综述。     

补肾固本方对大鼠骨质疏松模型中PI3K/AKT/mTOR信号通路表达的调控研究

目的观察补肾固本方对去卵巢骨质疏松(osteoporosis,OP)大鼠骨组织中PI3K/AKT/mTOR信号通路的影响,探讨补肾固本方干预OP的作用机制。方法将100只SD大鼠随机分为5组:正常组(C组)、模型组(M组)、补肾固本方组(B组)、补肾固本方+PI3k受体特异性阻断剂LY294002组(B+L组)、PI3k受体特异性阻断剂LY294002组(L组),除正常组外,其余4组建立去卵巢大鼠OP模型。药物连续干预12周后,采用ELISA方法检测血清中E2、BGP、ALP水平,实时荧光定量聚合酶链式反应(Real-time PCR)检测各组股骨组织中LC3、Beclin1、caspase-9 mRNA的表达情况,蛋白质印迹法(Western blot)检测各组股骨组织中PI3K、AKT、mTOR蛋白的表达。结果补肾固本方可显著增高OP大鼠血清E2水平,降低BGP、ALP水平,显著上调LC3、Beclin1表达水平,降低caspase-9、PI3K、p-AKT、mTOR的表达;而上述变化能够被PI3k受体特异性阻断剂LY294002所阻断,且其差异具有统计学意义(P0.05)。结论补肾固本方减少去卵巢后大鼠OP的发生,其机制可能与抑制PI3K/AKT/mTOR信号通路及其下游基因蛋白表达有关。
