重症急性胰腺炎102例临床分析

目的探讨重症急性胰腺炎的合理治疗方案。方法以1985年1月～2005年8月间收治的102例重症急性胰腺炎作研究对象，比较手术组与非手术组的主要并发症和死亡率。A组：1985年1月～1993年12月以手术治疗为主41例；B组：1994年1月～2005年8月以早期非手术治疗为主61例。结果手术组死亡率和并发症发生率明显高于非手术组，两组病死率及并发症发生率比较差异有显著性（P〈0．05）。结论重症急性胰腺炎采用早期非手术治疗能有效降低病死率和并发症发生率。大多数重症急性胰腺炎可经非手术治愈。     

钛瓷瓷裂的临床研究和原因分析

目的：分析钛-瓷修复体失败的原因。方法：对38例瓷裂的钛-瓷修复体进行分析：①肉眼观察烤瓷崩瓷部铸件的表面颜色并用便携式厚度测试仪测量其厚度，与未发生瓷裂的正常镰铬合金烤瓷比较；②观察烤瓷崩瓷的部位；③X-ray检测铸件内部气孔。结果：本组崩瓷的钛-瓷修复体，其断层或有气泡，或金属表面氧化层明显增厚（P〈0．05）。而且，所有发生崩瓷的部位均在受力点或因技工本身操作不当引起。结论：钛-瓷修复体失败的原因与加工过程中工艺、瓷的受力点以及与钛元素化学性能有关。     

不同性别的大学生心理健康调查研究

目的：探讨不同性别的大学生心理状况的影响。方法：以260名大学生为研究对象，采用SCL-90对不同性别的大学生进行了评定。结果：女生在抑郁、焦虑和恐怖方面高于男生，两者均存在显著性差异（P〈0．01）。结论：大学生中女性学生存在一定的心理缺陷，应针对性地开展专业教育，帮助大学生建立稳定、乐观和积极进取的健康心理。     

Blunted renal dopaminergic system activity in puromycin aminonucleoside-induced nephrotic syndrome.

BACKGROUND: A primary tubular sodium handling abnormality has been implicated in the edema formation of nephrotic syndrome. Dopamine synthesized by renal proximal tubules behaves as an endogenous natriuretic hormone by activating D(1)-like receptors as a paracrine/autocrine substance. METHODS: We examined the time courses of the urinary excretion of sodium, protein and dopamine in puromycin aminonucleoside (PAN)-treated and control rats. The rats were sacrificed during greatest sodium retention (day 7) as well as during negative sodium balance (day 14) for the evaluation of renal aromatic l-amino acid decarboxylase (AADC) activity, the enzyme responsible for the synthesis of renal dopamine. Also, the influence of volume expansion (VE) and the effects of the D(1)-like agonist fenoldopam (10 microg/kg bw/min) on natriuresis and on proximal tubular Na(+),K(+)-ATPase activity were examined on day 7. RESULTS: The daily urinary excretion of dopamine was decreased in PAN-treated rats, from day 5 and beyond. This was accompanied by a marked decrease in the renal AADC activity, on days 7 and 14. During VE, the fenoldopam-induced decrease in proximal tubular Na(+),K(+)-ATPase activity was more pronounced in PAN-treated rats than in controls. However, the urinary sodium excretion during fenoldopam infusion was markedly increased in control rats but was not altered in PAN-treated animals. CONCLUSION: PAN nephrosis is associated with a blunted renal dopaminergic system activity which may contribute to enhance the proximal tubular Na(+),K(+)-ATPase activity. However, the lack of renal dopamine appears not to be related with the overall renal sodium retention in a state of proteinuria.     

新氨基糖苷类抗生素89－07给药方案研究

用小鼠败血症系统感染模型，以感染小鼠肾匀浆活菌计数为标准，以庆大霉素为对照药，探讨日剂量单次与分两次给药两种方案对新氨基糖苷类抗生素８９—０７体内抗留作用的影响。结果表明大肠杆菌９０－０２０、绿脓假单胞菌３—３７４、金葡球菌９０—５０６对抗生素８９—０７和庆大霉素均敏感（ＭＩＣ范围０．０６２５～２ｍｇ／Ｌ）；抗生素８９—０７和庆大霉素日剂量单次给药组（ＯＤ）３株实验菌的肾匀浆活菌计数值由给药前的４．９４±０．０９、４．６０±０．２７、４．８６±０．１０１ｇｃｆｕ／ｍｌ分别降至１．９４±０．１９、１．８４±０．２５、１．８８±０．２５１ｇｃｆｕ／ｍｌ（给药后７～８ｈ）．日剂量分两次给药组（ＢＩＤ）则分别降至２．９５±０．４８、２．８７±０．３７、３．４４±０．２７１ｇｃｆｕ／ｍｌ。ＯＤ组对３株实验菌的最大杀菌作用Ｅｍａｘ分别为３．０２、２．９７和２．８５１ｇｃｆｕ／ｍｌ，ＯＤ给药方案的体内杀菌作用明显优于ＢＩＤ方案。     

Acute Immobilization Stress and Intraventricular Injection of CRF Suppress Naloxone-Induced LH Release in Ovariectomized Estrogen-Primed Rats

The present study was undertaken to evaluate the role and possible interaction of the endogenous opioid peptide (EOP) and corticotropin-releasing factor (CRF) in the acute stress-induced suppression of gonadotropin secretion in ovariectomized estrogen-primed rats. An intravenous (i.v.) injection of naloxone (10 or 20  mg/kg), an EOP antagonist, significantly elevated serum luteinizing hormone (LH) levels within 10  min in non-stressed animals. The naloxone-induced LH release was completely eliminated when tested 30  min after the onset of acute immobilization. In a subsequent study, it was found that suppression of the naloxone-induced LH release occurred as early as 5  min after the stress onset, and was still evident 60  min after the end of a 30-min period of immobilization. The effect of naloxone was restored 3  h after liberation of the animal from the 30-min immobilization. An intraventricular (i.c.v.) injection of CRF (1 or 5  μg) also significantly suppressed, in a dose-related manner, the effect of a subsequent i.v. injection of naloxone. However, an i.c.v. injection of α -helical CRF(9-41) (25 or 50  μg), a CRF antagonist, prior to immobilization, could not interfere with the suppressive effect of stress on naloxone-induced LH release. These results suggest that both acute immobilization stress and CRF can inhibit the LH secretory activity without mediation by EOP neurons. However, the stress-related suppression may involve non-CRF mechanism(s).
