The traditional Chinese medicine Antiinflammation No6, composed of Flos Lonicerae, Herba Taraxaci, Folium Isatidis and Herba Houttuyniae and proved to be highly effective clinically in the treatment of certain acute bacterial and viral infections, has been found in the present study to inhibit the prostaglandin E productin by zymosan-stimulated rat peritoneal macrophages (RPM?). In contrast, the production of lysozyme by non-stimulated RPM?, as well as the expression of C_3b receptors on the macrophage plasma membrane, was markedly enhanced by the drug. All these results seem to be in accordance with the authors' speculation that the basic mechanisms underlying the clinical effect of the drug may well be due to, at least in part, its potentiating action on the immune system.

0.05). The duration of normoglycemia in experimental group was 23～65 days (mean 48 days), while 3～6 days (mean 5 days) in control group, with the difference being very significant between the two groups (P

Objective To preliminarily evaluate the effect of endoscopy in treatment of subcutaneous hematoma in the limbs. Methods From March 1998 to October 2001, endoscope techniques were ferformed in 7 cases of old subcutaneous hematoma, among which were 2 cases of subcutaneous hematoma on the lateral femur, 1 on the medial knee joint, 1 on the traumatic prepatellar bursa and 3 on the anterior tibia. The area of the biggest hematoma was 20 cm?5 cm and that of the smallest 4 cm?6 cm. Results All the patients were followed up with a time range of 3-16 months and got sound healing with no scar in the skin and deeper tissues, pain or dysfunction. Conclusions The endoscope for larger subcutaneous hematoma in the limbs has the advantages such as smaller incision, less scar, accurate manipulation,mild postoperative reaction and fast recovery. Therefore, it can not only obtain similar curative effect to that of the traditional open operation but also avoid the shortcomings of the traditional operation. Endoscope techniques should be the first alternative to hematoma of over 5 cm or hard subcutaneous hematoma in the limbs.

[Objective]To introduce the knowledge for the diagnosis of acute gout arthritis that attacked initially in the knee and improve its early treatment.[Method]Seventeen cases with acute gout arthritis in the knee were diagnosed and treated under arthroscopy since 2000.The experiences were analysed retrospectively and the therapatic results were observed through a follow-up of more than 6 months.[Result]Before arthroscopy,only 5 cases were considered as acute gout arthritis,the other 12 cases were given a misdiagnosis.All the patients were diagnosed and given a debridment simutaneously under arthoscopy.Then,the patients were given an postoperative systematic drugs therapy.The follow-up(ranged from 10 to 24 months)showed that all the patients acquired a short-term and long-term satisfactory therapeutic effect.[Conclusion]The acute gout arthritis attacked initially in the knee is rare and its misdiagnosis rate is very high.The significant improvement and extensive application of arthroscopic techniques will improve its diagnosis rate and provide a new way for its early surgical treatment.

With the expansion of the overseas students in China,the psychological health education has been paid more and more attention.For the weak ability of conflicts management,prominent communication barrier and inveterate cultural difference,a preliminary study of convergence education of psychological health for overseas students is conducted in the perspective of positive psychology by building students'positive emotional experiences,cultivating students' positive qualities,as well as optimizing ideological education environment,around the theme as well as the virtues underlined in the theory of positive psychology on the basis of the convergence experiences of Chongqing Medical University.

Objective To investigate the influence of pretreatment with anti-B lymphocyte serum on the immunogenecity and endocrine function of islet preparations.Methods Porcine ICCs were pretreated with anti-B lymphocyte serum which was produced using the mixed adult porcine B lymphocyte as antigen.The immunogenecity of islet was measured by mixed islet lymphocyte culture (MILC) and SLA-DR positive cell number within the islet and the islet function was assayed with insulin release test.Results The cpm value of MILC of the group pretreated with anti-B lymphocyte serum and the MHCⅠ antigen and SLA-DR antigen positive cell numbers was markedly decreased in comparison with that of control group ( P

Objective To survey the prevalence of diabetes mellitus in adults of urban inhabitants of Shanghai. Methods Of 9376 adults aged 30 years and over, 1137 whose capillary blood glucose concentrations≥6. 7mmol/L 2 hours after 100g steam-bread meal underwent to OGTT and measurement of height.body weight and WHR. WHO (1985) standard was used as diagnostic criteria, the results were compared with those diagnosed with ADA (1997) criteria. Results According to WHO criteria,the prevalence rates of DM was 4. 16 %,and the prevalence rate of IGT was 4. 26%. But according to ADA(1997) criteria, the prevalence rate of DM was 4. 76%. The prevalence rate of DM and IGT were significantly increased with increasing age in those aged over 40. The prevalence rates of DM and IGT were much higher in patients with BMI≥25 than in those with BMI

Objective To analyse the causes of complications and accidents of arthroscopy and a discussion of the preventive measures. Methods 1 540 cases of arthroscopy were carried out from May 1980 to May 1999, including 1 426 cases of the knee, 59 of the ankle, 17 of the wrist, 21 of the first metatarsophalangeal joint, 8 of the hip, 6 of the elbow and 3 of the shoulder. Results Surgical instruments (blade, tip of forceps) broken in the articular cavity took place in 8 cases, injury of the normal tissue including the cartilage, meniscus, and ligaments happened in 40 cases, nerve branch and vascular injured around the inlets in 11 cases, water seeping out in 13 cases, infection following the formation of hematoma in 5 cases, refracture of patella during operation in 1 case, myocardial infarction after operation in 1 case, totally, complications and accidents were seen in 79 cases (5.1％ ). Conclusion Arthroscopic complications are mainly related to unskillful manipulation of the instruments, poor team work, inadequate exposure of intra-articular structure and negligence of timely replacing the nearly worn parts of the apparatus. The complications can all be prevented by improving above mentioned points.

Objective To study the changes of the rat's hearing threshold by long-term treatment with Vitamin-C and the reason of the changes. Methods Forty-two Wistar rats were randomly divided into two groups: the treatment group was treated with water added Vit-C and the placebo group was treated with drinking water.(1)Concentrations of malondialolehyde(MDA)of the cochlea with fluorescence chromatometry.(2) Auditory sensibilities with auditory brainstem response testing.(3) The frequency of the mtDNA~(4834)bp deletion in the cochlea with polymerase chain reaction technique. Results Hearing threshold of both groups become worse with aging,and the treatment group showed the better auditory sensitivities,the less concentrations of MDA and the less frequency of mtDNA~(4834)bp deletion compare with the placebo group. Conclusions Long-term treatment with Vitamin-C could reduce the degree of hearing loss of the rats and the concentrations of MDA of the cochlea and the frequency of mtDNA~(4834)bp deletion in the cochlea.The oxygen radicals theory should be the etiology of presbyacusis.
