掌侧锁定接骨板与普通接骨板治疗桡骨远端骨折疗效的比较

目的 比较掌侧锁定接骨板与普通接骨板治疗桡骨远端骨折的长期疗效.方法 对2005年9月-2007年11月间,采用切开复位掌侧锁定接骨板或普通接骨板内固定的45例随访资料完整的患者,进行两种疗法的比较.其中23例行锁定接骨板内固定,22例行普通接骨板内固定.按照AO分型:A型11例,B型11例,C型23例.随访内容包括:腕关节活动度(屈曲、背伸、尺偏、桡偏),前臂旋前、旋后活动范围,影像学资料(尺偏角、掌倾角、桡骨高度),应用DASH上肢功能评定标准和Gartland/Wertey腕关节评分法进行评分.结果 术后随访时间平均为18.8个月(12～36个月).腕关节活动度中,锁定板组背伸及两组的桡偏范围低于Gartland/Werley腕关节评分的基本范围.两组DASH值、腕关节活动度及前臂旋转范围,握力、捏力的恢复差异无统计学意义.Gartland/Werley腕关节评分普通接骨板治疗组优于锁定接骨板治疗组,差异有统计学意义.掌倾角均值两组都低于正常范围,尺偏角与桡骨高度均值在正常范围内,两组间差异无统计学意义.结论 掌侧锁定接骨板与普通接骨板在桡骨远端骨折治疗中具有相同疗效.

Quinone oxidoreductase (NQO1) gene polymorphism may not confer a susceptibility to mood disorders

Quinone oxidoreductase (NQO1) plays a key role in the cellular antioxidant defense by detoxifying quinine derivatives. Case-control association study of the possible relationship between the NQO1 gene polymorphism and mood disorders (patients with major depressive disorder, n=61; patients with bipolar I disorder, n=80; control, n=106) was carried out using PCR-based techniques. These preliminary results showed that the NQO1 gene polymorphism was not related to a susceptibility to mood disorders.

4-Acetyl-12,13-epoxyl-9-trichothecene-3, 15-diol from Isaria japonica mediates apoptosis of rat bladder carcinoma NBT-II cells by decreasing anti-apoptotic Bcl-2 expression and increasing pro-apoptotic Bax expression

We studied the effect of 4-acetyl-12,13-epoxyl-9-trichothecene-3, 15-diol (AETD) isolated from Isaria japonica, one of the most popular Chinese fungal medicines, on the induction of apoptosis in rat bladder carcinoma NBT-II cells. AETD was cytotoxic to NBT-II cells, and this cytotoxic effect appears to be attributed to its induction of apoptotic cell death, as AETD induced nuclear morphological changes and internucleosomal DNA fragmentation, and increased the proportion of hypodiploid cells and activity of caspase-3. AETD treatment also decreased the expression of the anti-apoptotic protein Bcl-2 and increased the expression of the pro-apoptotic protein Bax. These results provide important information in understanding the mechanism(s) of AETD-induced apoptosis.

No evidence for interaction between 5-HT2A receptor and serotonin transporter genes in schizophrenia

This study was to aim at investigating the potential interaction for the serotonin receptor gene (5-HTR) 2A and serotonin transporter gene (5-HTTLPR) polymorphisms in the development of schizophrenia, as well as the interaction of the two polymorphisms in relation with symptomatology, family history, age of onset and antipsychotic response. Genomic DNA analysis with polymerase chain reaction (PCR) was used for the genotyping. One hundred and eleven (111) patients with schizophrenia and 172 normal controls participated in the study. We did not find any association between the individual polymorphism and schizophrenia. The significant interaction effect between 5-HTTLPR and 5-HTR2A polymorphisms on the development of schizophrenia as well as on the antipsychotics response, family history, symptomatology and age at onset, was not found. However, subject with 5-HTR2A*TT genotype were found to have lower age of onset, compared to their counterparts (p=0.01). These results suggest that the interaction between 5-HTTLPR and 5-HTR2A polymorphisms may not contribute to susceptibility to schizophrenia as well as some clinical factors such as antipsychotic response, at least in the Korean population.     

胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.
