育龄妇女月经周期中心血管功能的变化

本研究采用先进的三维超声成像技术及多普勒技术对正常育龄妇女月经周期中心血管功能进行研究。结果：月经周期中ＨＲ、ＢＰ无变化；血清Ｅ２是周期性变化，排卵前达高峰。ＳＶ、ＣＯ、ＥＦ在排卵前期升高达峰值，显著高于月经期和黄体期；ＳＶＲ排卵前期最低，而Ｖｅｄ、Ｖｅｓ无变化。Ｖｍａｘ、Ａ、Ｅ在内源性Ｅ２高峰时明显加快，而Ｅ／Ａ比值无明显变化。结果提示：月经周期中随内源性Ｅ２的周期性变化，心脏功能也发生周期性变化。Ｅ２高峰时，心输出量、心搏量和射血分数达最高。外周阻力最低，心脏内血流速度加快。     

Clinical and experimental study of xiao er ke cuan ling oral liquid in the treatment of infantile bronchopneumonia]

Xiao Er Ke Chuan Ling Oral Liquid (KCL) is a Chinese herbal preparation consisted of 10 herbs such as Prunus armeniacae, Scutelaria baicalensis, Lonicera japonica etc. 30 children suffering from bronchopneumonia and/or acute bronchitis were treated with KCL (treated group) and another 30 cases were treated with penicillin and aminophylline (control group). Results: cure rate and effective rate in treated group was 26.6%, and 93.3% respectively. While in control group was 30% and 96.6% respectively. No significant differences were seen between them(P > 0.05). The pharmacodynamic experiment showed KCL had potent pharmacological action. The experiment on tracheal fragment of Guinea pig in vitro showed it caused moderately strong smooth muscle relaxation, through inhibition the effect of histamine and acetylcholine. Asthma induction experiment of Guinea pig in vivo showed KCL could significantly prolong the latent period of asthma and alleviate asthmatic symptom. Ammonium water cough induction experiment in mice showed it may apparently prolong cough latent period and reduce times of cough relapse and alleviate cough symptom. KCL had potent antipyretic effect on fever model induced by triple vaccine in rabbits. Bacteriostatic and antiviral experiment in vitro showed the drug had quite strong inhibitory effects for Streptococcus hemolyticus, Staphylococcus aureus, Flexners Dysentery bacillus, Diplococcus pneumoniae and Pseudomonas aeruginosa, and it could potently inhibit the respiratory syncytial virus. KCL is an effective drug in treating bronchopneumonia and acute bronchitis.     

An etiological study on fulminant viral hepatitis]

Viral markers were studied in 79 cases of viral hepatitis with hepatic failure. The results were shown as follows: 8 cases were positive for anti-HAV IgM (10.12%); 76 cases positive for HBsAg or anti-HBc IgM (96.20%) and 41 cases positive for anti-HCV antibodies (51.89%). Among those with anti-HCV positive, 35 cases were co-infected with HBV, 5 cases with HAV and/or HCV, only one was infected with HCV alone 2 cases were HD-Ag positive (2.52%) and one not identified (1.27%). With the reference of clinical findings, patients co-infected with HBV/HCV or anti-HBc IgM positive were more critical and usually entail higher mortality. In cases with HCV co-infections, the positive HBV replication markers seems to be reduced. Hepatic failure without HBV replicative markers had a high rate of hepatic coma as well as poor outcome.     

不典型脑转移瘤CT和MR的诊断分析

目的：提高CT与MR对不典型脑转移瘤的诊断准确性。方法：回顾性分析58例经临床手术证实的有完整资料的不典型脑转移瘤的CT和MR表现。结果：病变大部分位于幕上，有钙化者较多，约2／3有强化和水肿，且多发。部分有出血和囊变。结论：不典型脑转移瘤的CT和MR表现多种多样，多发者相对容易诊断，单发者诊断不易。颅外肿瘤的检查有助于鉴别诊断。肺部的影像学检查是必不可少的。     

显微内窥镜下治疗腰椎间盘突出症和腰椎管狭窄症

目的探讨显微内窥镜(MED)治疗腰椎间盘突出症和腰椎管狭窄症的临床效果。方法MED下切除增生内聚的关节突、肥厚的黄韧带及突出的椎间盘，彻底解除对硬膜、神经根的压迫。结果随访324例，按中华骨科学脊柱学组腰背痛手术评定标准，优297例，良14例，差13例，疗效优良率达96．0％，结论MED损伤小、恢复快、疗效好。
