Objective To explore the expression of COX-2 and p38MAPK in patients with trauma MODS. Methods Forty MODS patients were evaluated. The levels of peripheral blood mononuclear cells COX-2 and p38MAPK in MODS patients and 40 normal controls was detected by enzyme linked immunosor-bent assay (ELISA). RT-PCR was used to measure the COX-2 mRNA and p38MAPK mRNA expression of in PBMCs. ANOV and correlation analysis were used in statistical analysis. Results The levels of COX-2 and p38MAPK of PBMCs and the mRNA expression in MODS group were higher than in control group (all P <0.05). The levels of COX-2 and p38MAPK of PBMCs and the mRNA expression in dead group were higher than in survival group( all P <0.05). The levels of COX-2 and p38MAPK of PBMCs were positively correlated, (r =0.6 147, P<0.01). The expression of COX-2 mRNA, p38MAPK mRNA of PBMCs and APACHE I scoring were positively correlated (r1 =0.5 009, P1 <0.05,r2 =0. 5 316, P2 <0. 05). Conclusions COX-2 and p38MAPK of PBMCs take part in the onset of MODS, and may service as index to judge the prognosis of MODS.

OBJECTIVE To study the clinical curative effect of Qigui Yishen decoction in the treatment of patients with chronic kidney diseases of spleen and kidney deficiency.METHODS Patients with chronic kidney diseases met the diagnosis criteria were divided into two groups.Both groups were given the high quality low protein,low salt,low fat,low phosphorus diet,and also given basic treatments such as correcting water and electrolyte disorders,acidosis,anemia,lowering blood pres-sure,anticoagulation and regulating lipid.On the basis of this,the treatment group was also given Qigui Yishen decoction o-rally.Objective indexes including kidney function,serum plasminogen activator inhibitor-1(PAI-1),transforming growth fac-tor-β1(TGF-β1)and changes of TCM syndrome scores were observed after four weeks.RESULTS After the treatment,TCM syndrome scores in two groups decreased significantly compared with pre-treatment(P<0.05~0.01),and the treatment group was better than the control group(P<0.05~0.01).PAI-1,ALB/Cr,TGF-β1 and IL-6 levels in two groups decreased significantly after treatment(P<0.05~0.01),and the treatment group was better the control group(P<0.05~0.01). CONCLUSIONS Qigui Yishen decoction has definite curative effect on protecting renal function and alleviating the progress of renal fibrosis,and its therapeutic effect may be related to the improvement of blood coagulation and endothelial cell function.

The study is a paticular embodiment of Chinese patent medicine based on biopharmaceutics classification system of Chinese materia medica (CMMBCS) , focusing on assessment of synchronization issues of dissolution that may affect the timing of the multicomponent absorption. The accumulative dissolution percentages of nine components in Gengen Qinlian tablets in different dissolution solvents and times were determined by HPLC. The dissolution curve was drew and its similarity was evaluated by similarity factors (f2) and cluster method. Results in this experiment showed that the components that peak 7 and peak 8 (baicalin) represented had poor similarity with the reference peak 2 (puerarin). Their similarity factors were both 43 in water dissolution media and 31 and 45 in pH 7.4 dissolution media, respectively. Components that peaks represented had better similarity with the reference peak 2 (puerarin) in other medium. It illustrated that components that peak 3,4,5,6 (berberine) represented had fully synchronous dissolution characteristics with the reference peak 2 (puerarin), components peak 1 and 9 represented had nearly fully synchronous dissolution characteristics with the reference peak 2 (puerarin), while components that peak 7 and 8 (baicalin) represented had no synchronous dissolution characteristics with the reference peak 2 (puerarin).

ObjectiveTo investigate the ratios of peripheral blood CD4+CD25highFoxp3+ regulatory T cells of systemic lupus erythematosus(SLE) patients,and explore its association with disease activity and nephropathy.MethodsPBMC lymphocytes in 42 patients with SLE and PBMC in 40 normal healthy donors were evaluated for the proportion of Treg cells,as a percentage of the total CD4+ cells,by flow cytometric analysis.Levels of mRNA for Foxp3 were measured with a real-time quantitative PCR.The proportion of Treg cells and its association with SLEDAI,nephropathy,serum anti-dsDNA antibody,and C3 levels were analyzed.Statistical analysis was conducted with t-test and Spearman's correlation analysis.ResultsPatients with active disease had statistically significantly lower levels of CD4+CD25highFoxp3+ Treg than normal controls [(4±3)% vs (7±4)%,P<0.05],while no significant difference could be found between patients with nonactive disease and normal controls(P>0.05).The percentage of peripheral blood CD4+CD25highFoxp3+ Treg/CD4+ in patients with active disease was significantly lower when compared to patients with non-active disease [(9±6)% vs (10±6)%,P<0.05],and it was related to the disease activity.SLE patients with nephropathy had significantly lower levels of CD4+CD25highFoxp3+ Treg and CD4+CD25highFoxp3+ Treg/CD4+ than patients without nephropathy(P<0.05).Foxp3 mRNA levels were lower in PBMC from active disease patients than those in non-active disease.In addition,there was a negative correlation between the populations of CD4+CD25highFoxp3+ and SLEDAI(r=-0.5892,P<0.05).There was a negative correlation between the percentage of CD4+CD25highFoxp3+/CD4+ and SLEDAI (r=-0.4962,P<0.05),while there was a positive correlation between the percentage of CD4+CD25highFoxp3+/CD4+ and C3(r=0.3867,P<0.05).There was a positive correlation between the populations of CD4+CD25highFoxp3+ and Foxp3 mRNA(r=0.6142,P<0.01 ).ConclusionThese suggest that the decrease of CD4+CD25highFoxp3+ Treg and Foxp3 mRNA expression may play a crucial role in the pathogenesis of SLE.

AIM: To observe the inhibition of c-Met inhibitor on proliferation of lens epithelial cells (LECs).METHODS: Human's LECs were cultured and hepatocyte growth factor (HGF) and K252a were added to second passage of cells supplied with Dulbecco's modified eagle's medium (DMEM). MTT assay was used to examine the proliferation of LECs, and Western-blot was used to detect the expression change of Bcl-2 and Caspase-3.RESULTS: The photodensity (A) of HGF (50nmol/L) + K252a (30nmol/L) was not significantly different from that of DMEM control (P>0.05). The expression of Bcl-2 and Caspase-3 were not significantly different from that in the control group.CONCLUSION: K252a, the inhibitor of c-Met, can effectively inhibit the proliferation of LECs.

Objective:To explore the main factors of hypothyroidism after radiotherapy and to identify the optimal thyroid dosimetric parameters by analyzing the dosimetric parameters of the thyroid.Methods:The general clinical characteristics and dosimetric parameters of 206 patients with nasopharyngeal carcinoma treated in Cancer Hospital of University of Chinese Academy of Sciences were collected, and the correlation between them and the incidence of hypothyroidism was analyzed.Results:The incidence of hypothyroidism in patients with nasopharyngeal carcinoma after radiotherapy was 50.49%(104/206). Univariate analysis showed that gender, N-stage, volume, mean dose, V 20Gy, V 25Gy, V 30Gy, V 35Gy, V 40Gy, V 45Gy of thyroid were associated with the incidence of hypothyroidism. Multivariate analysis demonstrated that volume (≤12.82 cm 3) and mean dose of thyroid were the independent risk factors of hypothyroidism. Mean dose of thyroid combined with volume could significantly predict the incidence of hypothyroidism after radiotherapy. Conclusion:Mean dose of thyroid ≤ 47.21 Gy is the optimal dosimetric parameter for radiation-induced hypothyroidism, especially the patients with thyroid volume ≤ 12.82 cm 3 should pay more attention to the protection of thyroid gland during radiotherapy.
