Marchiafava-Bignami disease treated by mianserin hydrochloride in short-term evaluated by neuropsychological analysis

Since 1903, Marchiafava‐Bignami disease has been recognized as a rare syndrome with focal demyelination and necrosis in the corpus callosum, which is usually found in chronic alcoholics. It extends into the neighboring white matter and occasionally as far as the subcortical regions. We report a Japanese patient with Marchiafava‐Bignami disease associated with alcohol abuse, who had traveled around Western Europe, North America and China for more than 30 years. As he suffered extreme delirium in the early stages we administered a low dose (10 mg) of mianserin hydrochloride. He was very irritable and uncooperative on admission, after 20 days his delirium had disappeared and his temper had become very calm and mild. After 40 days, his intelligence level increased substantially as measured by various neuropsychological tests.     

1142例胃癌切除术围手术期死亡因素分析

目的研究影响胃癌围手术期死亡的主要因素,为指导选择合理的切除范围和手术方式提供依据。方法回顾1989年1月至2004年3月胃癌手术后1142例患者的临床资料,按照不同年代分为3组,第1组:1989年1月至1994年1月,405例;第2组:1994年2月至1999年1月,377例;第3组:1999年2月至2004年3月,360例。比较3组间的围手术期死亡率,采用Logistic多因素回归分析研究影响手术死亡率的危险因素。结果全组患者术后并发症发生率和死亡率分别为11.2%(128/1142)和3.6%(41/1142)。第1、2、3组的术后并发症发生率依次为13.1%、10.1%和10.3%;3组比较,P>0.05。3组手术死亡率依次为4.7%、3.4%和2.5%,3组比较,P>0.05。术后最常见的并发症是吻合口瘘(24.2%,31/128),影响手术死亡的主要因素为临床Ⅳ期、姑息性切除术、联合脏器切除及术前合并症的存在(P<0.05)。Logistic多元回归分析显示淋巴结的清除范围和手术方式不是影响手术死亡的主要因素(P>0.05)。结论胃癌晚期患者手术死亡率高,对胃癌Ⅳ期患者行姑息性切除手术时应避免施行不必要的淋巴结清除及联合脏器切除术。     

高龄急性脑梗死患者阿替普酶静脉溶栓有效性、安全性及预后影响因素分析

目的 探讨高龄急性脑梗死患者接受阿替普酶静脉溶栓治疗有效性、安全性和临床预后的影响
因素。
方法 前瞻性连续纳入江苏省苏北人民医院2016年9月-2018年9月收治入院进行阿替普酶静脉溶
栓治疗的急性脑梗死患者，按照年龄将患者分为年龄≥80岁组和年龄＜80岁组。比较两组患者入院
时、溶栓24 h NIHSS评分，6个月mRS评分及死亡率，观察两组溶栓相关出血转化、症状性颅内出血及
肺部感染的发生情况。应用多因素Logistic回归分析观察所有患者静脉溶栓预后的独立影响因素。
结果 最终共纳入患者119例，男性69例（58.0%），年龄范围46～94岁，平均70.12±10.55岁，入院
NIHSS评分4～38分。其中年龄≥80岁患者29例，年龄＜80岁患者90例。静脉溶栓后，两组患者溶栓
24 h NIHSS评分较入院时均明显降低（均P＜0.05），两组治疗24 h NIHSS评分比较差异无统计学意义；
两组的出血转化、症状性颅内出血、肺部感染、6个月预后良好及死亡率比较，差异均无统计学意义。
多因素Logistic回归分析显示，入院到静脉溶栓时间、入院时NIHSS评分及肺部感染是脑梗死静脉溶
栓6个月预后的独立危险因素（P＜0.05），高龄不是影响预后的因素（P＞0.05）。
结论 高龄急性脑梗死患者静脉溶栓治疗安全有效，未增加颅内出血转化风险、死亡率及不良预
后。入院到静脉溶栓时间、入院时NIHSS评分及肺部感染是急性脑梗死患者静脉溶栓6个月预后不良
的独立危险因素。

罗格列酮对糖尿病大鼠肾脏保护作用机制的探讨

目的 探讨罗格列酮对糖尿病大鼠肾脏的保护作用机制。方法 将大鼠分为正常组、糖尿病组、小剂量罗格列酮组、大剂量罗格列酮组。药物干预4周后，检测各组大鼠的血糖（BS）、三酰甘油（TG）、胆固醇（TC）、肌酐（Scr）水平及尿白蛋白定量（24h）。随后处死大鼠，测定肾组织中丙二醛（MDA）含量、总抗氧化能力（T-AOC）及铜锌超氧化物歧化酶（Cu-ZnSOD）、谷胱甘肽过氧化酶（GSH-Px）、核转录因子-κB（NF-κB）的活性。同时留取。肾脏组织作PAS染色行病理检查。RT-PCR和免疫组化法检测。肾组织中单核细胞化学吸引蛋白质1（MCP-1）mRNA及蛋白质的表达。结果 与糖尿病组相比，大剂量罗格列酮干预组BS、TC、TG差异无统计学意义；而。肾组织MDA含量、MCP-1mRNA及蛋白质表达、NF-κB活性差异有统计学意义（P〈0．05），SOD、GSH-Px、T-AOC活性显著上升；肾小球面积及体积减小。结论大剂量的罗格列酮可显著改善糖尿病大鼠的。肾脏损害，其机制可能与其抗氧化，抑制NF-κB活性，降低MCP-1的含量有关。     

Association of the GNAS1 gene variant with hypertension is dependent on alcohol consumption.

The beta-adrenoceptor (beta-AR)-stimulatory guanine nucleotide-binding (Gs) protein system has been shown to play important roles in the cardiovascular system. The gene encoding the alpha-subunit of Gs proteins (GNAS1) is a candidate genetic determinant for hypertension. Because alcohol consumption is known to affect blood pressure partly through the beta-AR-Gs protein system, we examined the possible interaction between GNAS1 T393C polymorphism and drinking status in the association with hypertension in the present study. As a result, a non-significant but reasonable trend supporting the presence of an interaction was shown (p = 0.076). In line with this trend, the T393C polymorphism significantly interacted with drinking status in the association with systolic blood pressure (p = 0.028). Moreover, supporting the presence of an interaction, T allele carriers consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than CC homozygotes in non-drinkers and light drinkers. In contrast, CC homozygotes consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than T allele carriers in moderate to heavy drinkers. The present study also showed a significant interaction between the T393C polymorphism and drinking status in the association with pulse pressure (p = 0.026), reflected by a significant association between the T393C polymorphism and pulse pressure in moderate to heavy drinkers (p = 0.026). These findings may be helpful in conducting further molecular and biological studies on the relationship among the effects of alcohol, the beta-AR-Gs protein system, and hypertension.     

蛋白酶对降低异常精液粘稠度的实验对比研究

目的通过不同蛋白酶类对降低高粘稠度精液的粘稠度效果对比,寻找理想的降低精液粘稠度的药物。方法将高粘稠度精液标本分为两组,A组:31例采用α-糜蛋白酶降低精液粘稠度:B组:32例采用尿激酶降低精液粘稠度;两组均观察用药前后的精子活动力。采用配对t检验和单因素方差分析对所得数据作统计学处理。结果高粘稠度精液用药物(α-糜蛋白酶或者尿激酶)液化精液后,精子的活动力较用药前有明显提高(P<0．001);用药前后精液的粘稠度都存在着明显的差异,精液的粘稠度分别下降44．83％和55．45％(P<0．001);在A组和B组的对比研究中,单因素方差分析检验提示:用药后两组间粘稠度数据有显著的差异(P<0．001￡(?)。结论蛋白酶可以有效地降低异常精液粘稠度的精液,从实验结果提示尿激酶降低精液粘稠度的效果优于α-糜蛋白酶,这有助于临床开展应用性研究和治疗。
