综合疗法治疗腰椎间盘突出症40例

目前治疗腰椎间盘突出症主要用椎间的旋转复位法，包括定点旋转复位和侧卧斜扳复位。自2004年8月以来，笔者在临床中遇到部分患者不配合或不能完成旋转复位法，因而采用自创凿击复位法，取得满意效果，现报告如下。     

Evaluation of modified hemodilution combined therapy in the treatment of acute ischemic stroke in the elderly

BACKGROUND: Thrombolysis therapy is not suitable for the elderly patients with acute ischemic stroke who delayed to be diagnosed for more than 3 hours, but traditional medicine is also not very ideal.OBJECTIVE: To observe the clinical therapeutic effect of modified hemodilution combined therapy applied in elderly patients with acute cerebral thrombosis and analyze the mechanism of this therapeutic method.DESIGN: 1:1 paired grouping according to gender and controlled observation.SETTING: Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University.PARTICIPANTS Totally 90 elderly patients with acute ischemic stroke who received the treatment in the Cadre Ward and Mental Ward, Department of Internal Medicine, Chengzhanyuan District, First Hospital Affiliated to Zhejiang University from March 1996 to June 2004 were recruited. They all met the diagnosis criteria revised by the Fourth Academic Conference of National Cerebrovascular Diseases in 1995 and were diagnosed as acute ischemic stroke by skull CT. They were informed of therapeutic plan and detected items.According to 1:1 paired principle in gender, 90 enrolled patients were assigned into treated group (n=45)and control group (n=45). There were 39 male and 6 female in the treatment group, and they were aged (76±6)years, ranging from 71 to 84 years, and hospitalized at the 14th to 76th hours after onset. There were 39 male and 6 female in the control group, and they were aged (76±6)years , ranging from 70 to 82years, and hospitalized at the 16th to 72th hours after onset.METHODS: Therapeutic method: Patients of treated group received modified hemodilution combined therapy.200 mL whole blood of patients was exchanged with 500 mL dextran-40 (including 20 mL danshen parenteral solution and 32 mg heparin) at the beginning of therapy; From the 2nd day, compound huangqi tea bag (Huangqi mainly, including danshen, honghua, chuanxiong, shishao and a little acetyl salicylic acid) was made, twice a day, 1 bag once. At the same time, the above-mentioned dextran-40 liquid of 500 mL was intravenously injected, once a day, 14 days in total; On the 6th day after therapy, the above-mentioned aseptic autoblood stored in refrigerator at 4 ℃ was transfused back into the patients following pre-treatment of high-concentration oxygenation and ultraviolet irradiation by light quantum instrument. Patients of control group were intravenously injected of 0.4 g venoruton(Traditional Chinese medicine compound parenteral solution for promoting blood circulation and removing blood stasis ) and 50 g/L glucose of 500 mL, 75 mg coagulation index, change of platelet aggregation rate and change of hemorrheology of patients in two groups were monitored before and after therapy. The level of blood lipid of patients in two groups was measured with American Beckman automatic biochemistry analyzer. Blood flow rate of middle cerebral artery of resting electrocardiogram were measured with American HP SONOS 2500 sonoscope. Neuro-dysfunction score revised in the national conference (1995) was used to evaluate the recovery of neurological function effect were observed at the same time.effect of drug.RESULTS: Totally 90 patients were enrolled in the experiment.

GENERAL SURGERY——Breast The effect of HO-1 activated via P38α pathway in the genesis and chemotherapy resistance of breast carcinoma

Objective To investigate the role of p38a pathway and HO-1 in the genesis and chemotherapy resistance of breast cancer. Methods The proliferation and apoptosis of human breast cancer cells were examined by MTT assay. The expression of p38a and HO-1 mRNA were examined by RT-PCR. Results The p38a mRNA level in 78 % of samples was significantly greater than that in the normal tissue and the p38a mRNA level in patients with lymph node metastasis was higher than that without lymph node metastasis （P 〈 0.01 ）. The HO-1 activated with 5 μmol/L pirarubicin increased more in MCF-7/adr cells than in MCF-7 cells, and was completely blocked by p38a inhibitor in MCF-7/ADR but only partially in the MCF-7 cell line.

The CLDN5 locus may be involved in the vulnerability to schizophrenia.

The present study was designed to detect three single nucleotide polymorphisms (SNPs) located on 22q11 that was thought as being of particularly importance for genetic research into schizophrenia. We recruited a total of 176 Chinese family trios of Han descent, consisting of mothers, fathers and affected offspring with schizophrenia for the genetic analysis. The transmission disequilibrium test (TDT) showed that of three SNPs, rs10314 in the 3'-untranslated region of the CLDN5 locus was associated with schizophrenia (chi(2) = 4.75, P = 0.029). The other two SNPs, rs1548359 present in the CDC45L locus centromeric of rs10314 and rs739371 in the 5'-flanking region of the CLDN5 locus, did not show such an association. The global chi-square (chi(2)) test showed that the 3-SNP haplotype system was not associated with schizophrenia although the 1-df test for individual haplotypes showed that the rs1548359(C)-rs10314(G)-rs739371(C) haplotype was excessively non-transmitted (chi(2) = 5.32, P = 0.02). Because the claudin proteins are a major component for barrier-forming tight junctions that could play a crucial role in response to changing natural, physiological and pathological conditions, the CLDN5 association with schizophrenia may be an important clue leading to look into a meeting point of genetic and environmental factors.
