The experience in the treatment of patients with extensive full-thickness burns

The aim of the present study is to analyze the changes of cure rate and the main causes of death in the last 40 years, and to summarize our experience in the treatment of extensive full-thickness burn patients. The clinical characteristics, cure rate and main causes of death of 73 cases with total burned area more than 90% TBSA and full-thickness burn area more than 70% TBSA were analyzed retrospectively. Among them, 21 cases (28.8%) were cured and 52 cases (71.2%) died. The cure rate increased significantly in the recent years, and the main causes of death changed from shock and sepsis in the time period 1959–1978 to sepsis and MODS in the past two decades. Due to the improvement of early comprehensive management of burn shock, aggressive surgical approach to full-thickness burn wound and potent systemic supporting measures, the survival rate increased significantly.     

弧菌,气单胞菌及邻单胞菌编码鉴定研究

采用编码技术对医学常见的弧菌属、气单胞菌属及邻单胞菌属的１２ 个菌种进行编码,建立了７ 位数编码鉴定法。并用此法鉴定了２０８ 株标准菌株,与常规鉴定法比较,两法无显著统计学意义（χ２ ＝０－４４ ,Ｐ＞０－０５）,符合率为９５－６７％ 。此鉴定法快捷、可靠、操作简便、判定结果简单、适合于临床、卫生及基层微生物实验室推广应用。     

Ramsay Hunt综合征的诊治

目的对Ramsay Hunt综合征(HS)临床和治疗进行分析,为了早期诊断和提高疗效.方法 84例HS病人平均年龄48.3岁,男女比为2.2:1,右侧发病多于左人侧(52/32).先有疱疹的63例,先有面瘫的21例,自觉听力障碍的57例,有眩晕的34例,治疗以保守治疗为主,无效者行面神经减压术.结果半规管功能受损者27例,中度以上听力受损者11例.经过治疗面肌功能完全恢复的达51.19%,总有效率为95.23%.结论对HS要早期诊断,及时治疗,注意鉴别诊断,面瘫保守治疗无效考虑面神经减压术.先出现疱疹的要比先出现面瘫的预后好.

地塞米松对去甲肾上腺素在孤束核引起的心血管活动的影响

目的：研究糖皮质激素对去甲肾上腺素在孤束核对心血管活动调节的影响。方法：向内侧和中间内侧孤束（ＮＴＳ）微量注射地塞米松（Ｄｅｘ）去甲肾上腺素（ＮＥ）,米非司酮及荷包牡丹碱（Ｂｉｃ）观察它们引起的心血管活动的变化。结果：Ｄｅｘ（０．３９ｍｍｏｌ．Ｌ＾－１,０．１μＬ）可以消除１０ｍｉｎ后在同一区域性注射ＮＥ（８ｍｍｏｌ．Ｌ＾－１,０．１μＬ）所引起的血压下降,心率减慢的效应,这种抑制作用４ｈ内不消失     

五种酚类抗氧化剂活性差异的理论解释

AIM: To verify the effectiveness of structure-activity relationship (SAR) and theoretical calculation methods for antioxidants. METHODS: Preliminary elucidation on the differences of activities of 5 antioxidants was performed by SAR. Then semiempirical quantum chemistry method AM1 was employed to calculate the delta HOF value, the difference between the heat of formation of antioxidant and its free radical, which was used as a theoretical parameter to elucidate the differences of activities of the antioxidants thoroughly. RESULTS: delta HOF values of antioxidants were obtained as follows: ferulic acid, 150.58 kJ.mol-1; anion of ferulic acid, 122.64 kJ.mol-1; modified ferulic acid, 137.70 kJ.mol-1; anion of modified ferulic acid, 118.99 kJ.mol-1; salvianic acid, 134.17 kJ.mol-1; rutin, 137.83 kJ.mol-1, L-EGCG, 124.39 kJ.mol-1; paeonol, 176.79 kJ.mol-1. The differences of the antioxidant activities were elucidated, and how to further enhance the antioxidant activity was investigated as well. CONCLUSION: The SAR and calculation methods are rather effective to elucidate the differences of antioxidant activities, and present some new clues for structural modification of antioxidants to increase their activities.     

生理性近视眼

作者统计分析1999名学生及学龄前儿童(4～18岁)正常眼的视力及睫状肌麻痹下的屈光,发现各年龄组屈光度都可计算出一定范围的正常值,并呈现正态分布曲线。结合其他观察比较,特提出生理性近视眼的概念,并就其表现特点及其与病理性近视眼的区别,作了详细讨论。对于人群中大量存在的生理性近视眼(或称单纯性近视眼),作者认为可看作是现代文明社会中的一种适应性结果,属于一类生物学变异,而不是一种眼病。     

HBV DNA含量与慢性乙型肝炎分析

目的　探讨慢性乙型肝炎患者血清中病毒血症水平与病情程度的相羞生。 方法　 采用FQ -PCR方法检测 12 6例慢性乙型肝炎轻、中、重度患者的血清HBVDNA含量。 结果　 慢乙肝轻、中、重度组HBVDNA含量分别是 (4 85± 1 0 )× 10 8- 10 7copy .ml、(3 82± 0 8)× 10 6- 10 5copy .ml、(1 8± 0 5 )× 10 5- 10 4copy .ml。结论　慢乙肝轻、中、重度各组之间的HBVDNA含量差异有显著性 ;中重度组病毒含量与总胆红素水平呈负相关 ,与白 /球比例呈正相关。     

孟鲁司特钠对大鼠异丙肾上腺素心肌坏死的保护作用

 目的观察白三烯受体拮抗剂孟鲁司特钠对大鼠心肌坏死的保护作用。方法大鼠皮下注射异丙肾上腺素(2 mg·kg^-1)造成心肌坏死模型，ig给予孟鲁司特钠，测定血清AST，LDH，CK，MDA含量，心肌NO含量和坏死心肌面积。结果大鼠预先给予孟鲁司特钠10.0，30.0 mg·kg^-1，可以降低血清LDH，CK，MDA含量，减少心肌坏死面积。孟鲁司特钠30.0 mg·kg^-1还能促进心肌NO释放。结论孟鲁司特钠对大鼠异丙肾上腺素心肌坏死具有保护作用，有进一步研制成心肌缺血治疗药物的可能。
