不同疗法对肌筋膜疼痛病人的自主神经功能的影响

目的：本研究的目的是观察注射疗法及复合小针刀疗法治疗肌筋膜疼痛综合征对自主神经系统功能的影响。方法：选择40例诊断明确的肌筋膜疼痛病人，随机分为两组，每组20例。Ⅰ组：采用注射疗法治疗；IS组：采用注射疗法加小针刀治疗。观察两组病人治疗前后心率变异（HRV）的频域变化，低频LF、超低频LLF、高频HF、低高频比LF／HF及心率变异指数HR-Ⅵ；用视觉模拟评分法（VAS）评定治疗前后疗效并随访观察其远期疗效。结果：①HRV频域指标组内比较：LF、LLF、HF以及HRVI治疗前舆治疗后1min比较有显着性差异（P〈0．05），与5min、10min比较有非常显着性差异（P〈0．01）。LF／HF治疗前与治疗后5min、10min比较有显着性差异（P〈0．05）。组间治疗后1、5、10min，两两比较无显着性差异。②组间比较：病人治疗后临床症状、VAS评分均较治疗前降低．治疗前后IS组有非常显着性差异（P〈0．01）。两组VAS降低率有非常显着性差异（P〈0．01）。③回访病例中，两组治疗有效率比较有显着性差异（P〈0．05）。结论：注射疗法以及复合小针刀疗法均可有效改善肌筋膜疼痛病人的自主神经功能，其机制可能是通过调节、稳定自主神经系统功能达到缓解疼痛。注射疗法复合小针刀疗法的远期疗效优于单纯注射疗法。     

霉酚酸酯对肾病综合征大鼠肾组织白细胞介素8的影响

目的 探讨白细胞介素8(IL-8)在肾病综合征大鼠蛋白尿形成中的作用及霉酚酸酯(MMF)对其的影响。方法 应用阿霉素肾病模型，用MMF对肾病形成过程进行干预。采用放射免疫法测定血清及肾组织IL-8含量。结果MMF可减轻肾病蛋白尿，降低肾组织IL-8含量。结论 MMF降低肾组织IL-8含量，可能是其对肾病综合征大鼠保护作用的机制之一。     

根管治疗术远期疗效的影响因素

根管治疗术（root canal therapy,RCT）是治疗牙髓病、根尖周病的主要方法.影响根管治疗术远期疗效的因素较多,而RCT前根尖周状态和根充位置是两大主要因素.     

碱性成纤维细胞生长因子（bFGF）加速猪背部创伤修复的实验研究

实验采用猪背部创伤模型，观察重组的碱性成纤维细胞生长因子（ｂＦＧＦ）对创伤修复的作用。在无菌条件下用特制打孔器在猪背部切割皮肤，形成２．５ｃｍ２的园型创面。将１５０个创面分成５组，分别以ｂＦＧＦ（６０ｕ／ｃｍ２创面），ｂＦＧＦ（（６０ｕ／ｃｍ２创面）加ＳＤ－Ａｇ、ＳＤ－Ａｇ、生理盐水以及不治疗等方法处理，每间隔一天换药一次。实验结果表明，ｂＦＧＦ具有显著促进肉芽组织生长、加速创面再上皮化率以及增加创面愈合组织抗张力强度等作用。ＦＧＦ显著促修复效应的确切机制尚不完全清楚，可能包括直接与间接效应两方面。     

Central circulation in rats with different tolerance to acute blood loss

Study of the dynamics of cardiac output in rats with different tolerance to acute massive blood loss showed that the pumping ability of the heart remains intact during the entire posthemorrhagic period in all high-resistant and in 65% low-resistant rats. In 35% rats that were low-resistant to blood loss, the cardiac output deficiency syndrome developed after cessation of bleeding against the background fall in arterial pressure and a decrease in the hepatic blood flow, which are the signs of rapid variant of the dysfunction produced by acute blood loss.

Midazolam in treatment of various types of seizures in children

Midazolam is a recently developed water-soluble benzodiazepine that shares anxiolytic, muscle relaxant, hypnotic and anticonvulsant actions with other members of this class. There are limited studies that midazolam can be used successfully to treat seizures in adults and children. In this study, 0.2 mg/kg intramuscular (IM) midazolam was administered to 11 children (eight boys and three girls), aged 3 days to 4 years (mean age 1.8±1.4 years), with seizures of various types. In all but one child, seizures stopped in 15 s–5 min after injection. No side effects were observed. These results suggest that IM administration of midazolam may be useful in a variety of seizures during childhood, especially in case of intravenous (IV) line problem.     

Effects of specific antibodies on the ultrastructure of mouse oocytes

The effects of antiovarian antiserum and monoclonal antibodies to the oolemma antigens on the ultrastructure of mouse oocytes and their microenvironment are studied. The antioolemma monoclonal antibodies cause more pronounced degenerative changes in the oocyte that in its microenvironment. Antiovarian antiserum induces greater changes in the microenvironment than in the oocyte. Changes induced in the oocyte by the antiserum are secondary relative to changes occurring in the microenvironment, while changes observed in the oocyte treated with monoclonal antibodies are primary.
