Safety and efficacy of oral nemonoxacin versus levofloxacin in treatment of community-acquired pneumonia: A phase 3, multicenter,randomized, double-blind,double-dummy,active-controlled,non-inferiority trial

Background/Purpose

Nemonoxacin is a novel nonfluorinated quinolone with excellent in vitro activity against most pathogens in community-acquired pneumonia (CAP), especially Gram-positive isolates. The purpose of this study was to assess the efficacy and safety of nemonoxacin compared with levofloxacin in patients with CAP.

原发性肝癌患者抑郁症状与不成熟防御机制的关系

目的：了解原发性肝癌（PLC）患者的抑郁症状和不成熟防御机制（IDM）的水平，探讨PLC患者的抑郁症状与IDM的关系。方法：采用流调用抑郁自评量表（CES－D）和防御式方式问卷（DSQ）对PLC患者和健康组各100例进行调查。结果：1）PLC患者中49％可能或肯定有抑郁症状，其中23％肯定有抑郁症状，其发生率高于健康组；2）PLC组的CES－D总分高于健康组；3）PLC组比健康组采用较多分裂和潜意显现机制，采用较少抱怨机制；4）肯定有抑郁症状者比无抑郁症状者采用较多IDM；5）两组CES－D总分与IDM均分呈显著正相关，Pearson r为0.473-0.776，其中PLC组为0．473。结论：抑郁症状是PLC患者常见的负性情绪，医护人员应引起重视，并指导患者采用成熟的防御机制代替不成熟防御机制，预防并减轻患者的抑郁症状，以提高患者的生活质量。

16例应激性溃疡的临床诊治体会

目的 报告应激性溃疡的临床诊治体会。方法 全组16例,男12例,女4例。术前均无溃疡病史,血红蛋白检查均正常。术后早期应用糖皮质激素9例,出血前发生肺不张、严重呼吸道感染、呼吸功能不全6例,低血容量休克5例,急性重症出血坏死性胰腺炎4例,食管癌、贲门癌术后6例,严重烧伤(80％(?)Ⅱ°)1例。14例保守治疗,2例保守治疗无效而手术治疗。结果14例经治疗后(2例手术治疗)痊愈出院,2例死亡。结论 应激性溃疡大出血患者多病情危重,难以忍受二次手术,死亡率约为50％,因此应采取有效的保守治疗,对于保守治疗无效、大出血休克或胃肠穿孔者应及时手术治疗。     

股骨粗隆间骨折采用改良L形钢板内固定的生物力学原理与临床应用

作者自1994年始采用自行设计L形钢板内固定治疗不稳定股骨粗隆间骨折60例，平均随访25个月，X线片显示骨折愈合时间6～13周，平均8．9周，伤肢功能在3个月内基本恢复正常，无骨折延迟愈合及髋内翻现象。为论证改良L形钢板的优点，本文采用8具新鲜尸股骨沿着它的外侧、内侧骨皮质粘贴6个应变片，观察股骨近端应变和位移分布，以检验改良L形钢板固定粗隆间骨折的效果。在实验前后将股骨粗隆造成二部分或四部分骨折。利用实验结果给制成应变和位移图，并与鹅头打固定组相比较。在载荷加至1800N时比较两种内固定器械的生物力学性能。结果表明，在治疗不稳定粗隆间骨折中，L形钢板比鹅头钉更具有生物力学的优势。     

脑卒中后癫痫60例临床分析

目的探讨脑卒中癫痫的，I岳床特点及发病机制。方法对1000例脑卒中患者中60例继发性癫痫患者的临床资料进行回顾性分析。结果脑卒中癫痫的总发生率6．00％，卒中后早期癫痫的发生率为53．33％（32／60），晚期发生率为46．67％（28／60），以部分发作为最多占65．00％（39／60），卒中后癫痫的发生率与病灶部位有关，皮质病灶较易发生卒中后癫痫，皮质（10．65％）与皮层下（2．73％）比较差异有显著意义（P〈0．05），而不同卒中类型癫痫发生率差异无显著意义（P〉0．05）。结论脑卒中是老年人癫痫发作的最常见原因，皮层病灶较易发生癫痫。     

Successful treatment of chronic idiopathic urticaria and angioedema with cimetidine alone

We have studied a 50-year-old white man with chronic urticaria and angioedema who has responded to treatment with cimetidine alone for over 2 yr. In a double-blind, placebo-controlled study, cimetidine alone was at least as effective as chlorpheniramine in relief of urticaria and angioedema. Additionally, cimetidine significantly inhibited (p less than 0.01) the wheal response to histamine when it was compared to placebo. The inhibition of wheal response to histamine by cimetidine was significantly higher (p less than 0.05) than chlorpheniramine. The presence of predominantly H2- rather than H1-histamine receptors in the cutaneous blood vessels may be responsible for the therapeutic effects of cimetidine in this patient.     

Relationships among genotypes, virulence and clinical forms of Sporothrix schenckii infection

This study explored the relationships among genotypes, virulence and clinical forms of Sporothrix schenckii. Genomic DNA from isolates of S. schenckii, collected from different clinical forms of sporotrichosis, was amplified by randomly amplified polymorphic DNA (RAPD). Suspensions of different isolates of S. schenckii were inoculated into healthy BALB/c mice to compare their virulence, and the numbers and distribution of spores were determined by histological analysis. RAPD analysis indicated that the isolates from different clinical forms of sporotrichosis belonged to different genotypes. The mice inoculated with isolates from disseminated sporotrichosis showed an earlier onset of illness and more severe lesions than those inoculated with isolates from lymphocutaneous sporotrichosis, which, in turn, showed an earlier onset of illness and more severe lesions than those inoculated with isolates from fixed cutaneous sporotrichosis. Healthy BALB/c mice injected with isolates from disseminated sporotrichosis died within 10 days, whereas isolates from lymphocutaneous sporotrichosis and fixed cutaneous sporotrichosis failed to cause death. Histologically, mice inoculated with isolates from disseminated sporotrichosis had more spores than those inoculated with isolates from lymphocutaneous sporotrichosis and fixed cutaneous sporotrichosis. Thus, different genotypes may be associated closely with the virulence of different clinical forms of S. schenckii infection.     

An epidemiologic approach to computerized medical diagnosis—AEDMI program

A program called “An Epidemiological Approach to Computerized Medical Diagnosis” (AEDMI) is presented. Using an interactive questionnaire, physician-patient interviews are conducted and a summary of the relevant clinical data is provided. Standard items, obained on a multi-centre basis, form a large-scale data base. Simultaneously, the reasoning of clinical experts in each real case is analyzed to obtain a knowledge-rules data base. The methodology of the program combines Bayesian systems, expert systems, and other new lines of researcg such as neural networks or case-based reasoning. The general concepts of clinical decision making aid systems are reviewed. This publication is aimed at obtaining international cooperation.     

90例小儿发热惊厥脑电图与临床预后关系

本文报告了90例发热惊厥(FC)患儿的脑电图检查结果,认为对FC患儿的脑电图检查时间应在退热至少2周后进行;FC起病年龄低者再发率高,且脑发育成熟前起病的FC患儿脑损伤轻严重;对于某些患者,引起FC的体温逐渐降低,这些患儿转为无热惊厥(癫痫)的可能性明显增高;家族史不仅会影响FC的发病倾向而且会影响FC的复发及转归。
