Up-regulation of Niacinamide in Intervertebral Disc Aggrecan in vitro

The regulatory effects of niacinamide （Nia） on intervertebral disc （IVD） aggrecan in vitro was investigated. Chiba＇s 10 ng/mL interleukin-1 （IL-1）-induced rabbit IVD degeneration model in vitro was established. 0.5, 0. 25 and 0.05 mg/mL Nia was added to normal and degenerated IVDs for intervention. On the first and second week after intervention, safranin O-fast green staining intensity and glycosaminoglycan （GS） content were measured. The expression of aggrecan core protein was detected by RT-PCR. The results showed： （1） After treatment with 0. 5 mg/mL Nia for one week, the GS content in nucleus pulposus （NP） was increased by 44.80% as compared with control group （P〈0. 01） ; The GS content in IL-1 induction groups was increased with the increase of Nia concentrations： After treatment with 0. 5 mg/mL for one week, the GS content in NP was increased by 68.30% as compared with control group （P〈0. 01）. After two weeks, GS content in NP and fibrous rings was still higher than in control group at the same period （P〈0. 01） and untreated group （P〈0.01）. （2） Safranin O-fast green staining revealed that with the increase of Nia concentrations, staining density in NP and fibrous rings was increased and histological structure damage to IVDs by IL-1β was alleviated. （3） RT-PCR showed that the expression of core protein gene in IL-1β-induced degenerated IVDS was increased with the increase of Nia concentrations. It was concluded that under conditions in vitro, Nia could up-regulate the expression of aggrecan in IVDs and protect IVDs from IL-1β-induced degeneration at least partially, which offers a potential choice for IVD degeneration clinical therapy.     

Brief Introduction to Digital Acupoint Pressure Therapy

The Concept of Digital Acupoint Pressure Therapy The digital acupoint pressure therapy means that according to different diseases and the illness condition, the physician strikes, presses or taps the acupoints with hands on the patient＇s body surface to promote the circulation of qi and blood, thus making dysfunctions of certain organs or the affected areas return to normal.

基于混合正态模型的糖尿病住院病人医疗保险设计

目的提出一种基于混合正态模型来拟合糖尿病住院病人风险损失规律的精算方法.方法采用EM算法对混合正态风险模型进行参数估计;采用Kolmogorov-Smirnov检验对混合正态风险模型的拟合优度进行检验;采用随机抽样模拟和t检验法比较随机样本指标与模型参数之间的差异;采用逐步判别分析方法,对随机保单进行分类与甄别;设计保险条款,作为保险双方有约束力的合同.结果由训练样本拟合得到四元混合正态模型;模型的拟合精度很高（P=0.99701）;按μi＋1.645σi可得到4种保险等级下的总保费;样本指标与模型参数之间的差异无统计学意义.结论 本文设计的面向糖尿病住院病人的医疗保险,可根据投保人因糖尿病住院风险损失额划分成4种类型保单持有者,并由此厘定出4种不同等级的保险费,因而体现了高风险损失应承担高额保险费的保险原则,有利于投保人根据自身情况选择保单类别.     

中西医结合治疗急性重症胰腺炎临床体会

目的探讨分析中西医结合治疗急性重症胰腺炎的疗效以及可行性。方法回顾分析我院1999年9月￣2005年9月收治的行中西医结合治疗的急性重症胰腺炎病人72例的治疗情况,与以往行手术治疗的治疗效果进行比较。结果治愈57例,治愈率79.2%,中转手术8例,死亡7例,死亡率9.7%,并发症发生率18%。结论中西医结合方法治疗急性重症胰腺炎的效果良好,可明显降低并发症发生率及死亡率。     

儿童伤害的流行现状与预防控制

凡由于能量(机械能、热能、化学能等)的传递或干扰超过人体的耐受性造成组织损伤,或窒息导致缺氧,影响了正常活动,需要医治或看护,称之为伤害[1]。伤害按其意图可分为意外伤害和故意伤害,常见的意外伤害包括道路交通伤害、溺水、跌伤、中毒和烧烫伤;常见的儿童故意伤害包括儿童     

铅对小鼠睾丸TGFβ1及Caspase-3表达的影响

目的 探讨不同浓度和时间醋酸铅染毒对小鼠睾丸转化生长因子β1（Transforming growth factor β1，TGFβ1）、半胱天冬酶3（Caspase-3）表达的影响，进一步阐明醋酸铅所致睾丸毒性的作用机制。方法 45只雄性小鼠分为空白对照组和0．2％，0．4％醋酸铅染毒组，每组15只。并在第2，4，6周分别处死每组小鼠各5只，取其睾丸组织，免疫组化检测TGFβ1、Caspase-3表达的差异。结果 染铅后不同周TGFβ1、Caspase-3的表达较空白对照组增强，差异有统计学意义（P〈0．05）。且随着染毒时间的延长，表达越强（P〈0．05）。但在0．2％与0．4％不同周染铅组之间TGFβ1、Caspase-3的表达差异并无统计学意义（P〉0．05）。结论 醋酸铅使睾丸TGFβ1 Caspse-3的表达增强，从而促使生殖细胞发生凋亡。
