电针巨刺对中风偏瘫患者甲皱微循环的影响

<正> 《灵枢·官针篇》说:“巨刺者,左取右,右取左”。巨刺治疗中风偏瘫早在元代就有记载。《济生拔粹·针经摘英集》曰:“治中风手足不遂,针百会、听会、肩髃、曲池、三里、悬钟、风市,其七穴左治右,右治左”。巨刺历来受到各家重视,但其依据何在?与针刺瘫痪侧肢体(下称瘫刺)是否有差异?作者试用电针巨刺对中风偏瘫患者甲皱微循环的影响进行了观察。     

Immune responses to the expressed products of the CSP antige n gene of Plasmodium falciparum southern China isolate FCC1/HN in Hela cell

Objective To construct a eukaryotic expression system with pcDNA3-PfCSP/Hela for the Circ umsporozoite protein (CSP) gene of Plasmodium falciparum (P.falciparum), t o observe the immune responses in BALB/c mice induced by the expressed proteins .Methods The recombinant plasmid pcDNA3-PfCSP was transformed into the Hela cell line. The expressed protein was isolated and analyzed by using SDS-PAGE and used for immunization of BALB/c mice by subcutaneous, intravenous, and intraperitone al adminstration.Enzyme-linked immunosorbent assay(ELISA), Dot-ELISA, Wester n blot, T lymphocyte proliferation test, natural killer cell(NKC) activity assay , and CD4(+) and CD8(+) T cell detection were used for observation of humoral an d cellular immune responses.Results Immune sera strongly reacted with the expressed protein, antibody titer was up to 1∶6400 as detected by ELISA.Western blot analysis revealed a specific b and at 38.3 Kda.When the spleen cells of normal and immunized BALB/c mice we re specifically stimulated with expressed protein, the optical densities were 0 .12±0.03 and 0.34±0.04, respectively.The latter were significantly highe r than the former (P&lt;0.01).We used the MTT colorimetric assay to measure NKC activity of mice spleen.The results showed that the NKC activity of immuni zed BALB/c mice was remarkably higher than that of the controls (P&lt;0.05). CD4(+) and CD8(+) T cells were detected by using monoclonal antibody immunofluor escence methods.The results showed that the percentage of CD4(+) and CD8(+) T cells of immunized group were significantly higher than that of control group ( P&lt;0.05).Conclusions The humoral and cell-mediated immune responses and elevated NKC activity to pr oducts made with a eukaryotic expression system could be specifically detected i n BALB/c mice.These findings indicate that the expressed protein could enhance the immune function in mice.

Studies on association between lipoprotein lipase gene polymorphisms of Pvu Ⅱ site and hypertriglyceridemics in Chinese

Objective To explore whether Pvu Ⅱ restriction fragment length polymorphisms (RFLP) in the lipoprotein lipase (LPL) gene are associated with hypertriglyceridemics (HTG).Methods Pvu Ⅱ restriction fragment length polymorphisms in the lipoprotein lipase gene on a sample of 135 HTG patients and 193 age-matched healthy individuals in Chengdu area were detected with the method of PCR-RFLP.Results The P+P+ genotype frequency and P+ allelic frequency of LPL gene for HTG cases are higher than those for control groups (0.460 vs 0.337, P<0.05; 0.689 vs 0.565, P<0.01). The serum levels of TG, apoC Ⅱ, apoC Ⅲ, apoE and TG/HDL-C in P+P+ genotype are higher than those in P-P- genotype (P<0.05).Conclusion The results suggest that P+P+ genotype in the lipoprotein lipase gene is associated with susceptibility to hypertriglyceridemics in Chinese population.     

51例闭经的临床分析和治疗探讨

目的 探讨闭经的病因、治疗方法及疗效。方法 对1989年2月－2001年2月间我院妇科内分泌治疗的51例闭经患者的临床资料进行回顾性分析,并根据患者的临床症状及血清激素水平特征归类讨论。结果 51例闭经患者,未婚8例,女婚43例,其中3例结婚时间短于半年,37例为不孕症者,占72．5％。多囊卵巢综合征（PCOS）21例（41．2％）;卵巢早衰（POF）18例（35．3％）;高催乳素血症（HPRL）6例;垂体微腺瘤4例;高雄激素血症（HT）2例。通过内分泌药物治疗后观察,PCOS患者的妊娠率为58．8％;POF患者中仅有1例妊娠;HPRL6例患者中有5例妊娠;垂体微腺瘤3例（已婚）中有2例妊娠;高雄激素血症的2例患者中1例妊娠。结论 闭经患者经过适当的治疗,除POF外其妊娠率效果较为满意。     

小鼠补体受体Ⅱ型基因改造后感染EB病毒

通过对小鼠补体受体Ⅱ型基因（CR2）进行定点突变,然后将野生型和突变型小鼠CR2/1（MCR2/1）及人CR2（hCR2)用电穿孔方法导入小鼠SP2/0进行表达,采用免疫组织化学等方法鉴定阳性细胞系。用EB病毒对转染阳性细胞进行感染,EBER-1杂交结果显示,仅转染hCR2和突变型MCR2（mtMCR2)的SP2/0细胞感染了EB病毒,前者感染EB病毒的阳性率较后者高很多。这为进一步研究EB病毒进入细胞的机制及建立EB病毒相关的鼻咽癌动物模型奠定了良好的基础。     

绝经后骨质疏松大鼠模型的综合评价

利用双能X线骨密度仪、扫描电镜和骨生物力学试验综合评价大鼠去卵巢后的骨骼状况。结果显示：①大鼠卵巢切除后,活体、离体腰椎以及股骨（除R3区）、胫骨近端干骺端（R1区）的离体骨密度显著下降（P＜0.01),离体L5和L6的骨丢失率最大,达13%;②骨小梁减少、变细,连接中断,骨小梁表面有吸收陷窝;③腰椎压缩强度和股骨力学性均下降,前者更明显,腰椎最大压缩力下降率达33.32%。提示：①类似于绝经后妇女,6月龄大鼠在卵巢切除4个月后骨量和骨质量均下降,特别在富含松质骨的部位,如腰椎、股骨远端等;②利用绝经后骨质疏松大鼠模型评价骨质疏松新药的有效性,应包括该新药对骨量、骨结构和骨强度的作用。     

中脑导水管周围灰质内注射抗强啡肽血清对神经降压素镇痛作用的影响

目的：探讨大鼠中脑导水管周围灰质（PAG）内内源性强啡肽对神经降压素（NT）镇痛作用的影响。方法：以钾离子透入法引起大鼠甩尾反应的电流强度（mA)为痛行为反应的指标,观察向PAG内注入NT,抗神经降压素血清和抗强啡肽A1－13血清对动物痛阈的影响。结果：PAG内注入NT后,大鼠痛阈明显升高;注入抗神经降压素血清后,大鼠痛阈则明显降低,而注入抗强啡肽血清后,对NT的镇痛效应无显著影响,结论：PAG内NT在痛觉调制中发挥着重要的作用,且其作用不依赖于PAG内的内源性强啡肽。     

3T3—L1脂肪细胞中高糖诱导胰岛素抵抗的分子机制

We investigated the cellular effect of high glucose using 3T3-L1 adipocytes on glucose transport activity, the expression of insulin signaling proteins and IRS1 tyrosine phosphorylation. Results showed that adipocytes treated with different high glucose (10, 15 and 25 mmol.L-1) for 24 hours showed to impair the basal and insulin-induced increase in glucose uptake in a dose-dependent manner and decreased significantly IRS1 tyrosine phosphorylation. High concentration of glucose produced opposite effects on IRS1 and IRS2: down-regulated IRS1 protein expression level and tightly up-regulated IRS2 contents. p85 and PKB were unaffected. Chronic exposure to high glucose can inhibit glucose uptake and induce insulin resistance. The mechanism may be involved in affecting the expression of insulin signaling peptides and tyrosine phosphorylation.     

先天性心脏病合并肺动脉高压患者体外循环围术期血浆内皮素水平的动态观察

应用放射免疫方法,对22例左向右分流型先天性心脏病合并肺动脉高压患者（肺高压组）及16例左向右分流先天性心脏病无肺高压患者（无肺高压组）体外循环心内直视手术围术期血浆内皮素水平进行了动态检测。结果发现：两者体外循环心内手术围术期血浆内皮素水平显著升高;无肺高压组术后血浆内皮素水平迅速下降并于手术后6h恢复至术前水平;肺高压组术后血浆内皮素水平下降缓慢,术后48h尚未恢复至术前水平。
