Objective:To detect mRNA expression of IL-6 and IL-8 in allergen-induced late-phase cutaneous reactions in schneiderian membrane subjects. Methods:Cryostat sections from rhinitis biopsies from 24 h allergen-induced late-phase cutaneous reactions (LPR) in 10human atopic subjects were hybridization with 35S-labeled RNA probes for IL-6 and IL-8.Results:mRNA was detected for IL-6 (9/10) and IL8 (10/10).Compared with the control, there were significant increases in the numbers of ce11 expreasing mRNA expression for IL-6 and IL-8(P＜0.05, P＜0.01). Conclusion: The augmentation of mRNA expression of IL-6 and IL-8 maybe regarded as the mark of rhinits in IL PR.

Objective To investigate the effect of milk basic protein (MBP) on bone metabolism in normal and ovariectomized (Ovx) rats. Method Forty-eight female Sprague-Dawley rats were ovariectomized and another 12 rats received sham operation (Sham). After 10 d recovery period, the Ovx rats were randomly divided into 4 groups: control, low-dose, medium-dose, and high-dose MBP group. Another 44 normal female rats without ovariectomy were also divided into 4 groups as above. The MBP dosages for each group were respectively 0, 10, 20, 30 mg/kg bw. All rats were i.g. administered for 90 d. Bone mineral density (BMD) of the femur (at proximal end, middle of diaphysis, and distal end) was measured by dual-energy X-ray absorptiometry in vivo. The amounts of calcium, magnesium and phosphorus were analyzed by ICP-AES. Results BMD at distal end of femur was significantly higher in normal low-dose group than in normal control group while no significant effect was observed in Ovx MBP groups. As for the amounts of calcium, magnesium and phosphorus, there were no significant differences among normal experimental groups and also among Ovx experimental groups. However, some variations in the level of those minerals were observed. Conclusion MBP at 10 mg/kg bw significantly elevated BMD at femoral distal end in normal rats, while no similar effect was observed in Ovx rats. Besides its influence on bone minerals, there may be another mechanism involved in its effect on bone metabolism.

Objective Face-down positioning after vitrectomy and gas tamponade is still the standard position for patients with rhegmatogenous retinal detachment.The study was to compare the nursing effects of face-down position and flexible position after vitrecto-my for the repair of rhegmatogenous retinal detachment. Methods We investigated 120 cases of patients with rhegmatogenous retinal detachment in this study.All patients received vitrectomy with long-acting gas for tamponade, 60 patients in face-down position and 60 in the flexible position.Patients were followed up for 6 months.Observation was made on the rates of anatomical retinal reattachment and postoperative complications between the groups. Results The rates of anatomical retinal reattachment after surgery were 88.33%in the face-down position group and 100% in the flexible position group respectively.As to the satisfaction of position, the flexible position group was 100%, which was much higher than 41.67%in face-down position group(P<0.01). Conclusion Flexible position nurs-ing after vitrectomy and gas tamponade for rhegmatogenous retinal detachment repair is safe and effective.Flexible position can replace face-down position for the comfort of patients with rhegmatogenous retinal detachment after vitrectomy with gas tamponade.

The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

Objective To investigate the features of renal lesion in patients with rheumatoid arthritis (RA). Methods The clinical pathology changes of 20 patients with renal lesion by RA were analyzed. Results The clinical features of patients showed chronic glomerulonephritis in 8 cases,nephritic syndrome 4 cases, chronic interstitial nephritis in 3 cases, chronic renal failure in 4 cases, and acute renal failure in 1 case. The patients with glomerulonephritis accompanied with the increase of immunoglobulin, erythrocyte sedimentation rate, C-reactive protein or rheumatoid factor. Kidney biopsy of 7 patients found membranous nephro-pathy in, IgA nephropathy in 3 and vasculitis in 1. Conclusion The common renal lesion in RA is glomerulonephritis, with mesangial proliferative glomerulonephritis or membranous nephropathy. One of the basic pathoh,gi,.al changes is vasculitis,which could result in necrotizing vasculitis.The disorder of immunologic function couht play important role in renal damage in patients with RA.
