Objective:To explore the mechanisms underlying the proliferative inhibition of Chinese herbal medicine Kang-Ai injection(KAI)in gastric cancer ***:Gastric cancer cell lines MGC803 and BGC823 were treated by 0,0.3%,1%,3%and 10%KAI for 24,48 and 72 h,*** cell proliferation was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide(MTT)*** apoptosis and cell cycle were evaluated by flow ***(IL)-6 mRNA and protein expression levels were detected by quantitative real-time polymerase chain reaction(qRT-PCR)and enzyme-linked immune sorbent assay(ELISA),*** protein expression levels of cyclin A,cyclin E,cyclin B1,cyclin D1,p21,retinoblastoma(RB),protein kinase B(AKT),extracellular regulated protein kinases(ERK),signal transducer and activator of transcription(STAT)1 and STAT3 were detected by Western ***:KAI inhibited the proliferation of MGC803 and BGC823 gastric cancer cells in dose-and time-dependent *** treated with KAI for 48 h,the proportion of G,phase was increased,expression level of cyclin D1 and phosphorylation-RB were down-regulated,whereas the expression of p21 was up-regulated(all P<0.01).Furthermore,48-h treatment with KAI decreased the phosphorylation level of STAT3,inhibited the mRNA and protein expressions of IL-6(all P<0.01).IL-6 at dose of 10 ng/mL significantly attenuated the proliferative effect of both 3%and 10%KAI,and recovered KAI-inhibited STAT3 phosphorylation and cyclin D1 expression level(all P<0.01).Conclusion:KAI exerted an anti-proliferative function by inhibiting IL-6/STAT3 signaling pathway followed by the induction of G_(1)phase arrest in gastric cancer cells.

为了保障再生水水质生物稳定性,控制再生水在储存、输配和利用过程中微生物生长,对再生水臭氧氧化处理工艺水质生物稳定性进行了研究。研究发现,臭氧氧化对再生水厂二级出水的溶解性有机碳（DOC）去除效果有限,对UV254和荧光强度有较好的去除效果,但可导致水样AOC水平升高,水质生物稳定性降低。分析臭氧氧化后不同有机物组分的变化情况,发现臭氧氧化对分子量为0.5~20 k Da有机物有较好的去除效果,而分子量小于0.5 k Da有机物没有明显变化。

目的探讨针刺联合人羊膜间充质细胞(human amniotic mesenchymal cells,HAMCs)移植对去卵巢骨质疏松协同效应研究。方法选择雌性未孕的Wistar大鼠45只,完全随机分组分为假手术组、模型组及实验组(针刺+人羊膜间充质细胞移植),每组各15只。各组手术伤口恢复后,第7天开行针刺+尾静脉注射HAMCs液(假手术组除外)连续干预12周,于末次干预后24 h,处死大鼠并采集标本。从开始干预至处死,每周测定1次各组大鼠的体质量,双能X线吸收骨密度仪分别测定左侧股骨中点、远端和近端骨密度,用原子吸收法测定其骨钙含量;干预12周后采用ELISA法检测血清25-羟基维生素D(25-HVD)、I型胶原C端肽(CTX-I)、骨特异性碱性磷酸酶(BAP)、抗酒石酸酸性磷酸酶5b(TRAP5b)的表达变化;干预12周后检测各组大鼠生物力学性能的变化。干预12周后RT-PCR技术检测椎骨中转化生长因子β1(TGF-β1)的基因表达情况。结果假手术组大鼠体重逐渐增加,符合动物自然生长规律,模型组于造模后两个月开始,体重却明显高于假手术组,实验组体重渐增,与假手术组相近。模型组比较假手术组的骨密度和骨钙含量均降低,差异具有统计学意义(P<0.05),与模型组较,实验组的骨密度和骨钙含量含量均升高,差异具有统计学意义(P<0.05)。ELISA法显示,血清25-HVD、CTX-I、BAP、TRAP5b的表达,与假手术组比较,模型组显著降低,与模型组比较,实验组显著升高,(P<0.05)。生物法力学检测显示,假手术组的极限载荷、极限应力和弹性模量比模型组有显著增高(P<0.05),实验组的极限载荷和弹性模量比假手术组有显著增高(P<0.05)。RT-PCR检测显示TGF-β1的m-RNA的表达,与假手术组、模型组比较,实验组明显上调(P<0.05)。结论针刺联合人羊膜间充质细胞(HAMCs)移植具有较好的对去卵巢骨质疏松协同效应,可改善去卵巢大鼠骨质疏松症的作用。

目的从中国基本医疗保险支付角度出发,预测将达格列净纳入国家基本医疗保险药品乙类目录后,未来5年对医疗保险基金支出可能产生的影响。方法基于中国糖尿病流行病学数据界定目标人群,并根据专家意见确定达格列净与市场现有药品的替代关系,构建预算影响分析模型。估算目标人群的药品费用与不良事件(心力衰竭住院、主要不良心血管事件、严重低血糖和肾病住院)相关医疗费用,预测达格列净进入基本医疗保险目录后对医疗保险基金支出的影响。结果若达格列净进入国家基本医疗保险目录乙类,2018—2021年对医疗保险基金支出的影响分别为+0.71、+1.41、+2.54、+1.87、-0.08亿元。敏感性分析结果显示,在多种不同情形下增量医疗保险基金支出差异不大。结论达格列净在进入医疗保险目录后的最初几年,会在一定程度上增加医疗保险基金支出。但随着达格列净用药人数的增加,其可以节约更多的不良事件相关医疗费用,长期来看会节省医疗保险基金支出。
