用酶联免疫吸附术观察向附睾注射鱼肝油酸钠后抗精子抗体的变化

本研究用酶联免疫吸附术观察8只家兔在附睾注射鱼肝油酸钠后血清及精浆中的抗精子抗体。血清抗精子抗体阳性率为37.5～50.0%,最早检出率为术后2个月,6～7月达高峰。精浆抗精子抗体阳性率为25%,最早检出率为术后4个月,且此时己达高峰。与输精管结扎资料相比,发现血清抗精子抗体检出率偏低,而精浆相应抗体偏高,表明向附睾注射鱼肝油酸钠引起的免疫反应有别于结扎,以生殖道局部为主。

BIOEQUIVALENCE BETWEEN rhGH FOR RECONSTITUTION AND READY-TO-USE rhGH IN TWO LIQUID FORMULATIONS

Objective To evaluate the bioequivalence between recombinant human growth hormone （rhGH） for reconstitution, and two dosages of liquid formulation of rhGH [ （151U） 5mg or （301U） lOmg per 3ml ]. Methods The study drugs were tested in a randomized, single-blind and three-period crossover studies in 24 healthy male subjects. The three drugs were administered by subcutaneous injection at a dose of O. 21U/kg body weight. A continuous somatostatin infusion was given in order to suppress the secretion of endogenous GH. The ve- nous blood samples were drawn at different time points to test the serum concentration of GH. The pharmacokinetic parameters were analyzed by statistical methods. Results 90% confidence intervals （CI） of AUC0-24h among three products were all within 80% - 125% interval （ 103. 4% - 116. 5%, 105. 7% - 119. 6% and 91.9% - 103. 7%, respectively）, and the Cls of C,~ among three products were all within 70% - 143% interval （91.9% - 114. 0%, 103. 7% -127. 2% and 81.6% -97. 4%, respectively）. There was no statisitical difference of tmax among all the three products. Conclusion These data demonstrate that there is bioequivalence between rhGH for reconstitution and two liquid formulations of rhGH.

口腔门诊治疗并发晕厥106例回顾分析

目的：通过对1983年以来，孝感市中心医院口腔中心门诊治疗并发晕厥106例的回顾性分析，探讨口腔门诊治疗并发单纯性晕厥的原因及一些相关因素，增强医患双方的防治意识，安全顺利的进行口腔门诊治疗。方法：对106例单纯性晕厥反应，采取现场询问式调查的方法，对其一般情况，口腔门诊治疗经历，治疗时的心态，口腔门诊治疗的了解，以及不同口腔治疗晕厥发生情况等进行调查、归纳、分析。结果：1)晕厥的发生与患者的年龄有关，12～40岁口腔门诊治疗经历欠缺的患者是口腔门诊治疗并发晕厥的高危人群。2)口腔患者进行治疗前心理准备充足与否对并发晕厥反应的影响较大。3)晕厥在口腔门诊某些治疗中发生率较高，拔牙术最多，其次为脓肿切排。86％(92例)属因畏惧疼痛导致紧张而诱发的血管抑制性晕厥。4)晕厥多发生于治疗初期(93：13)。结论：口腔门诊治疗并发晕厥临床表现多不严重，但对患者就诊和医师的治疗影响明显，切实做好口腔治疗错误信息，消除和减轻他们的疑虑和畏惧的紧张心情，对保障口腔门诊治疗安全尤为重要。

Non-immune therapy of IgA glomerulonephritis

Summary: The involvement of the IgA immune system and complement components in IgA glomerulonephritis (IgAGN) has prompted the use of immunosuppressive drugs in therapy, but none has so far been shown to alter the natural course of the disease. Because most patients with IgAGN present during the chronic phase of their illness, at the time when the initiating immune events may no longer be active, nonimmune therapy which targets the common pathway of progressive renal injury is likely to be more useful. There is increasing evidence that angiotensin-converting enzyme inhibitors (ACEI) reduce proteinuria and renal injury in patients with IgAGN, and this effect may be observed in both normotensive and hypertensive patients. Yet to be determined is whether this effect is specific for ACEI and whatever other effective antihypertensive drugs may achieve a similar result. Fish oil has recently been shown to retard the progression of renal failure in patients with aggressive IgAGN, but a narrow therapeutic window appears to exist for this form of treatment. Antiplatelet agents on their own appear to be ineffective but in combination with anticoagulation (low dose warfarin) have been shown to have an antiproteinuric effect and may preserve renal function in patients with progressive disease. Future directions of non-immune therapy of IgAGN include evaluation of the renoprotective effect of angiotensin II receptor antagonists, free-radical scavengers and antilipid drugs. More work should also be done to identify factors which put the patients at risk of developing progressive disease and which predict therapeutic response, as has been done recently with the identification of the deletion polymorphism of the angiotensin-converting enzyme gene as a marker of progressive disease and therapeutic response to ACEI in patients with IgAGN.
