眼轴线后部眶容积增大与眼球内陷比值的测定研究

目的:通过测量眼眶爆裂性骨折伴有眼眶扩大患者的后部眼眶容积、观察眼球内陷出现的时间及程度,研究后部眶容积扩大与眼球内陷的关系比值,为病情预测和眶内填充手术提供比较精确的参考数据。方法:将96例患者按发病时间分为早期病例组(60例、受伤时间1周以内)和晚期病例组(36例、受伤时间3个月以上),早期组除进行后部眼眶容积测量外,分别于1周、2周、3周测定眼球突出度(相差>1mm为阳性),记录眼球内陷出现时间,用卡方检验进行统计学分析;晚期组测量后部眶容积增大值和眼球内陷量,对其相关性采用Pearson统计方法进行统计学分析,并得出回归方程及相关系数。结果:早期组60例患者中,(58.33%)例患者在1周内出现眼球内陷,4(880%)例在2周内出现内陷,3周时有5(388.33%)例呈现出内陷;2周时出现眼球内陷的例数与1周时有显著性差异(χ2=62.484,P<0.001),2周时出现眼球内陷例数与3周时无差异(χ2=1.563,P>0.05),1周时出现眼球内陷例数与3周时有显著差异(χ2=76.885,P<0.001),后部眶容积增大与眼球内陷的比值约为1.0,两者之间呈正相关(r=0.994,P<0.001),即后部眶容积每增加1ml,产生1.0mm的眼球内陷。结论:眼球内陷通常于伤后2周～3周出现,3个月时趋向稳定;后部眶容积增大与眼球内陷产生比值为1.0,呈正相关;后部眶容积扩大与眼球内陷比值可预测发生眼球内陷的可能性和程度,为手术矫正眼球内陷提供可靠、精确的参考,具有十分重要的临床指导意义。

P17 Pharmacology in the integrated course ＂Basic Medical Sciences＂ in Zhejiang University School of Medicine

According to traditional teaching mode, the courses in preclinical medicine including pharmacology are separately run. This mode causes a series of disadvantages including loose connection between knowledge in different disciplines and weak ability to bridge basic preclinical knowledge and clinical practice. In order to overcome the disadvantages and promote the teaching efficiency, we constructed a new integrated course-Course of Basic Medical Sciences, which includes 6 traditional courses, anatomy, histology and embryology, physiology, pathology, pathophysiology and pharmacology. We integrated these courses based on the human organ systems and according to the principle-＂ From macro to micro, From morphological to functional, From normal to abnormal and From disease to drug therapy＂ and published the series of textbook in 2004. The contents of pharmacology are taught just after pathology and pathophysiology in every organ system. In comparison with the traditional teaching mode, teachers of pharmacology need not spend a lot of time to review preceding knowledge of anatomy and histology, physiology, pathophysiology and pathology. This is helpful in saving time and improving the teaching efficiency.     

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。     

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.

Inhibitory effect of glycyrrhiza uralensis fish and chelidonium majus L on gastrocarcinogenesis induced by N-methyl-N′-nitron-N-nitrosoguanidine

In order to investigate the antagonistic effect of Glycyrrhiza Uralensis Fish (GUF) and Chelidonium maJus L (CML) on gastrccarcinogenesis induced by MNNG in Wastar rats, we treated the rats with MNNG alone (group 1) and with MNNG plus GUF and CML (group 2 and 3) respectively. The incidence of infiltrating adenocarcinoma of the glandular stomach and duodenum in group 2 was significantly lower than that in group 1 (26.7% vs. 67.8%). The differentiation and aggressivenees of carcinomas occured in group 2 were much better and mild than those in group 1. Present study also demonstrated that the inhibitory effect of CML on proliferation of human stomach carcinoma cell line MGC-803 was very remarkable; in addition, GUF and CML were able to antagonise the mutagenic activation of MNNG. These results suggest that GUF and CML may be empoyed in prevention of gastric carcinoma.
