不同孔径骨修复材料消旋聚乳酸对骨再生的影响

目的：探讨不同孔径三维多孔骨修复材料DL－PLA植入兔桡骨骨缺损区对骨长入的影响，方法：将采用浇注盐析技术制成的孔隙率为75％而孔径不同的三维多孔DL－PLA材料植入兔桡骨骨缺损区，并设立空白对照组，分别在术后2，4，8，12周行X线检查，取材做大体观察，组织形态学检查，生物力学检测，结果：植入材料孔径为约250，400，750μm者均有大量新生骨组织形成，而植入孔径约为75μm者及空白对照组12周时民损区两端骨髓腔已闭合，植入250μm者8和12周时抗弯强度最高（P＜0．01），结论：三维多孔材料孔径大小对骨长入起决定性作用，孔径为约250um的材料最有利于骨长入。     

甜梦口服液配伍安定治疗顽固性失眠临床应用研究

失眠症是由多种因素引起的临床常见病症,患者难以入睡或睡后易醒,严重影响工作学习和日常生活.尤其是顽固性失眠,给予传统镇静催眠药(如安定)后效果不理想,由于病程较长,常引发精神异常和其他功能障碍,使患者身心遭受严重伤害,带来巨大痛苦.笔者在临床中用甜梦口服液配伍安定治疗顽固性失眠效果显著,故在动物实验的基础上制定了临床观察计划,对其配伍应用效果进行对比研究,现报告如下.     

Preliminary study on the nucleic acid hybridization technic in detecting HSV-2 DNA corresponding sequence of cancer tissues of the uterine cervix

In this paper, 34 samples, 25 from 18 cervical carcinoma patients and 9 from 8 non-cervical carcinoma patients, were assayed using (alpha-32P) dCTP HSV-2 DNA probe and nucleic acid hybridization technic. It was shown that the positive rates of HSV-2 DNA corresponding sequence were 50% (2/4), 36% (5/14) and 12% (1/8) in the in situ cancer, invasive cancer and non-cervical cancer tissues. No HSV was isolated from 7 cancer specimens which showed a positive reaction by nucleic acid hybridization.     

Genetic diversity and molecular identification of mosquito species in the Anopheles maculatus group using the ITS2 region of rDNA.

The species diversity and genetic structure of mosquitoes belonging to the Anopheles maculatus group in Southeast Asia were investigated using the internal transcribed spacer 2 (ITS2) of ribosomal DNA (rDNA). A molecular phylogeny indicates the presence of at least one hitherto unrecognised species. Mosquitoes of chromosomal form K from eastern Thailand have a unique ITS2 sequence that is 3.7% divergent from the next most closely related taxon (An. sawadwongporni) in the group. In the context of negligible intraspecific variation at ITS2, this suggests that chromosomal form K is most probably a distinct species. Although An. maculatus sensu stricto from northern Thailand and southern Thailand/peninsular Malaysia differ from each other in chromosomal banding pattern and vectorial capacity, no intraspecific variation was observed in the ITS2 sequences of this species over this entire geographic area despite an extensive survey. A PCR-based identification method was developed to distinguish five species of the group (An. maculatus, An. dravidicus, An. pseudowillmori, An. sawadwongporni and chromosomal form K) to assist field-based studies in northwestern Thailand. Sequences from 187 mosquitoes (mostly An. maculatus and An. sawadwongporni) revealed no intraspecific variation in specimens from Thailand, Cambodia, mainland China, Malaysia, Taiwan and Vietnam, suggesting that this identification method will be widely applicable in Southeast Asia. The lack of detectable genetic structure also suggests that populations of these species are either connected by gene flow and/or share a recent common history.     

可切除原发性十二指肠恶性肿瘤X线征象分析

目的 :对可切除的原发性十二指肠恶性肿瘤X线征象进行分析。方法 :对 2 6例原发性十二指肠恶性肿瘤胃肠道造影及CT征象进行了回顾性对比分析总结。结果 :全部病例均经手术病理证实 ,其中腺癌 2 2例 ,平滑肌肉瘤 3例 ,非何杰金氏淋巴瘤 1例。描述包括肿瘤的部位 ,造影X线表现 (黏膜破坏 ,充盈缺损及龛影 ,管腔不规则狭窄 ,肠腔外改变等 )及CT表现 (肠壁增厚肠腔狭窄 ,局部肿块 ,梗阻性改变及转移 )。不能手术切除的影像学征象为 :肿瘤直径大于 6cm ;腹腔、系膜淋巴结成团肿大 ;腔静脉、肠系膜动静脉等重要血管管径被包绕大于 2 / 3时。结论 :CT与X线造影对肿瘤的位置、大小、形态 ,肿瘤的继发征象的术前评价 ,能够提供能否手术切除的重要依据。     

近端胆管癌的外科治疗

目的 探讨近端胆管癌的外科治疗及疗效。方法 57例近端胆管癌患者中21例行外科手术治疗,36例行非手术外引流治疗。结果21例手术治疗患者中17例存活14月以上,36例行鼻胆管引流或内置管引流术患者均在8月内死亡。结论 外科手术治疗近端胆管癌疗效明显优于鼻胆管引流术（ENBD）或内置管引流术（EHBD）胆管内外引流。     

细菌性痢疾季节性高峰变化及其与气温关系的研究

目的 探讨气温对细菌性痢疾发病的影响。方法 应用相关回归统计法和圆形分布法对资料进行研究。结果 菌痢的月平均发病百分构成比与相应年份月平均气温呈正相关(r=0.5099,P<0.01);辖区近10年的平均气温较前10年有所上升,尤其秋冬季与初春月平均气温升高了1℃左右,而菌痢发病高峰时点明显后移(F=11.49,P<0.01),流行高峰期也有后移倾向。结论 气温对菌痢的发病有直接影响,气温升高,菌痢的发病增加,年平均气温升高可导致菌痢的发病高峰时间后移。
