To study the contribution of T cell subsets in the pathogenesis of Murine hepatitis virus Type3 (MHV-3) induced chronic viral hepatitis in C3H/Hej mice, ninety C3H/Hej mice were chosen to individually receive 10 plaque forming units (PFU) of MHV-3 intraperitoneally. The changes of virus titer and pathology in liver tissue were examined by standard plaque assay and by the hematoxylin/eosin (HE) staining method from 2 days post MHV-3 infection. The ratios of T cell subsets including CD3+CD4+CD8-, CD3+CD4-CD8+, CD3+CD4-CD8-, CD3+CD4+CD25+, CD3+CD4+CD25- and CD3+CD4-CD25+ T lymphocyte of total T lymphocytes in blood, spleen and liver were examined at 0, 2, 4, 6,8, 10, 12, 15, 20, 25, 30, 40 days post MHV-3 infection by flow cytosorting. We observed that the virus titer raised and showed persistent virus duplications and inflammatory changes in the livers of C3H/Hej mice from 2 days post MHV-3 infection. The double negative T cell (DN Treg cell) and CD4+CD25+ T cell ratios increased significantly from 2 days post MHV-3 infection in C3H/Hej mice, and CD3+CD4+CD8-, CD3+CD4-CD8+, CD3+CD4+CD25- and CD3+CD4-CD25+ T cell ratios decreased accordingly. In conclusion, the changes of virus titer and pathology in the livers of C3H/Hej mice post MHV-3 suggest their contribution to viral persistence. Further characterizations of DN Treg cells are that infection indicates that MHV-3 could induce the chronic inflammation in livers of C3H/Hej mice.The increase of the DN Treg cell and CD4+CD25+ T cell ratios in C3H/Hej mice post MHV-3 infection suggests that DN Treg cells and CD4+CD25+ T cells may both have important suppressive immunomodulation functions in the development of chronic viral hepatitis and have important roles in the virus persistent infection. Further characterizations of DNT cell and CD4+CD25+ T cell are under investigation.

Objective To investigate the changes of calcium /calmodulin - dependent protein kinase Ⅱ (CAMKⅡD) gene expression in 3T3 - L1 preadipocyte diffe-rentiation and TNF - ? regulation of CAMKⅡD gene expression on matured adipocytes. Methods 3T3 - L1 preadipocytes were cultured and differentiated into adipocytes. The levels of CAMKⅡD gene mRNA expression at various times were evaluated by RT-PCR. Matured adipocytes were interfered with 0.1,1.0,10.0 ?g/L TNF - ? and the levels of CAMKⅡD gene mRNA expression were evaluated. Results The levels of CAMKⅡD gene mRNA expression in 3T3 - L1 adipocytes were significantly down- regulated at first day, compared with those at zero day (P0. 05). CAMKⅡD gene mRNA expression decreased significantly at 12 hours after treatment with 10.0 ?g/L TNF-?, treatment of matured adipocytes with TNF - ? did not have any regulation role on it. Conclusions CAMKⅡD gene is involved in the differentiation of adipocytes and related to the etiology of obesity. The changes in the level of CAMKⅡD gene mRNA expression during 3T3 - L1 preadipocyte differentiation may contribute to the differentiation and adipogenesis of adipocytes. It seems that TNF - ? does not have any regulation role on the expression of CAMKⅡD genes.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

OBJECTIVETo assess the quality of life (QOL) in long-term survivors with acute leukemia (AL).

METHODSNinety-five long-term survivors with AL drawn from 29 hospitals in Shanghai during the period 1984 - 1994 were studied. Questionnaire FACT-G was completed in order to assess the QOL for long-term survivors with AL.

RESULTSQuestionnaires assessing QOL were filled in by 95 long-term survivors with AL. Majority of the survivor turned out having normal QOL. The average QOL score was 85. Patients aged over 60 years old and illiterate had higher QOL score. About 50% of the patients had returned to full-time job or school. 12.6% of the patients had had secondary diseases due to chemotherapy. Nearly half of the married patients were not satisfied with their sexual life.

CONCLUSIONThus, prevention of having secondary diseases and to keep sexual function must call for serious attention during chemotherapy. The biggest challenge was to prevent relapse and the affordability to treatment.

Orobanche caerulescens is an important medicinal resource in Orobanchaceae. The present study aims to establish methods for determination of acteoside, crenatoside, and total phenylethanoid glycosides in O. caerulescens, and determine the content in 15 samples to evaluate the resource utilization of this medicinal plant. The content of acteoside and crenatoside were quantitatively determined by HPLC, while total phenylpropanoid glycosides was estimated by UV-VIS spectrophotometry. According to the results, the content of acteoside was the highest in O. caerulescens, followed by crenatoside. The contents of acteoside, crenatoside, and total phenylethanoid glycosides were between 1.15% - 15.60%, 0.83% - 4.47%, and 6.78% - 27.43%, respectively, which had significant differences. The acquisition time has great influence on the content of main components of O. caerulescens. The content of phenylethanoid glycosides is higher in the samples which were collected at the flowering stage. The two determination methods were proved to be simple, accurate and reliable, and can be used to evaluate the quality and resource utilization of O. caerulescens.
