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.

Objective To observe the growth and differentiation of the cultured mouse bone marrow stromal cells in vitro into neural like cells. Methods Bone marrow stromal cells (BMSCs) isolated from mice were cultured according to the routine method, and induced to differentiate by basic fibroblast growth factor b (bFGF), retinoic acid (RA), nerve growth factor (NGF), and dimethylsulfoxide (DMSO). Expressions of neural microfilament protein (NF 200), glial fibrillary acidic protein (GFAP), and fibronectin at 72 h after inductin were determined by immunoflurenscence and immunocytochemicalmethod. Results At 72 h after inductin, neural like changes were found in BMSCs. Immunohistochemical stain showed that 60% BMSCs differentiated into NF 200 positive cells, and about 50% BMSCs into GFAP positive cells. Fibronectin expression was significantly lower as compared with that in the control group. Conclusion Combined action of RA, bFGF, NGF, and DMSO can induce BMSCs to differentiate into neural like cells in vitro .

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 pretr eatment with anti-B lymphocyte serum on the immunogenecity and endocrine functi on of islet preparations.Methods　Porcine ICCs were pretre ated with anti-B lymphocyte serum which was produced using the mixed adult porc i ne B lymphocyte as antigen.The immunogenecity of islet was measured by mixed isl et 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 lymphocy te serum and the MHCⅠ antigen and SLA-DR antigen positive cell numbers was mar kedly decreased in comparison with that of control group (P＜0.001).There wa s no significant difference in insulin release of additional different groups.[ WT5”HZ Conclusion　The pretreatment of islet preparation with anti -B lymphocyte serum may decrease the immunogenecity of islet preparation,while there is no marked influence on its insulin release function.

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 enhance the understanding of the diagnosis of benign tumor in the knee joints.[Method] Thirteen patients(9 males and 4 females,aged 7 to 49 years,38.2 years arerage)with tumor in the knee joints were diagnosed and treated under arthroscopy since 1996.There were 3 with the synovial hemangioma,2 with tensoynovial giant cell tumor,4 with ganglion cysts of cruciate ligament and synovial cysts,1 with chondroma in the soft tissue,2 with desmoid tumor in the cruciate ligament and 1 with cruciate ligament desmoid.The curative effects were observed through a follow-up of more than half a year.[Result]All the cases were diagnozed under arthroscope and confirmed by the pathological examinations.All the patients were treated under arthroscope and followed by 11 months to 6 years.Clinical symptom improved obviously and no recurrence was found after the operation.Assessment of the curative effects were 46% excellent,39% good and 15% fair.[Conclusion]Benign tumor in the knee joints is rare.It's often difficult to diagnoze in the clinical practice.Arthroscopy is a very useful method for the diagnosis and treatment of the suspected patients with benign tumor in knee joints.

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.
