Objective To study the effects of total saponins of Chaenomeles speciosa on release of β-hexosaminidase from rat basophilic leukemia-2H3 ( RBL-2H3 ) mast cells. Methods After rat RBL-2H3 mast cells were prepared, total saponins of Chaenomeles speciosa and the RBL-2H3 mast cells were co-cultured.The toxic effects of total saponins of Chaenomeles speciosa on mast cells were detected by MTT method, β-hexosaminidase release rate was measured by fluorescence quantitative spectrophotometric method, and cell supernatants of tumor necrosis factor-α( TNF-α) release were detected by ELISA. Results After total saponins of Chaenomeles speciosa were co-cultured with RBL-2H3 mast cells with different antigen stimulation, β-hexosaminidase release rates and the levels of TNF-α of mast cells significantly decreased compared with the control group. Conclusion Total saponins of Chaenomeles speciosa inhibit the degranulation of RBL-2H3 mast cells in a dose dependent manner, which provids basis for studying mechanism of inhibiting allergic reactions.

Objective To explore the relationships of post- traumatic growth with self- care efficacy and psychological resilience in patients with breast cancer. Methods Totally 303 patients with breast cancer were investigated with Post- traumatic Growth Inventory (PTGI), Chinese version of Strategies Used by People to Promote Health (C- SUPPH) and Connor- Davidson Resilience Scale (CD- RISC). Results The total score of PTGI was 63.74±13.00 and the status of post- traumatic growth in breast cancer patients was in middle level, with a highest interpersonal score of 24.49±5.05, a lowest mental change score of 3.84± 1.91. Correlation analysis showed that post- traumatic growth was positively correlated with the level of self- care efficacy and psychological resilience (P<0.01 or 0.05). Regression analysis showed that self- care efficacy and psychological resilience in breast cancer patients could effectively predict the post- traumatic growth with an explanation rate of 36.1%. Conclusions Self- care efficacy and psychological resilience in patients with breast cancer are closely correlated with post- traumatic growth. It is suggested to take appropriate measures to promote post-traumatic growth of the breast cancer patients.

Objective:To investigate the effects of Qingluotongbi granule(QLT) on RANKL(receptor activator of nuclear factor-?B ligand) expression in peripheral blood T lymphocytes of RA patients.Methods:RANKL expression of peripheral blood T lymphocyts was examined using flow cytometry.Six cases of RA patients were enrolled with six healthy volunteers as the control.Meanwhile examination for the level of RANKL expression in T cells after incubation in presense of QLT-contained serum was observed.Results:RANKL expression of peripheral blood T lymphocytes was much higher in active state RA patients than in healthy people(P

AIM: To observe the effect of Qingluo Tongbi Granule(QLTBG)——containing serum on the proliferation of osteoblasts(OB) and osteoclasts(OC),the activity of AKP of OB. METHODS: (1) OB were separated from the skull of SD rats aged 1 d and OC from the thighbone and shinbone of SD rats aged 5 d.(2) The proliferation of OB and OC was detected by MTT method,and the activity of AKP of OB was examined by diazol method. RESULTS: The proliferation capability of OB was strengthened markedly by the rat sera containing 7.2,14.4 g/kg QLTBG,which could reinforce the activity of AKP obviously as well,while the proliferation of OB was inhibited remarkably by the rat sera containing 3.6,7.2,14.4 g/kg QLT. CONCLUSION: The sera containing QLTBG could enhance the proliferation of OB and the activity of AKP,restrain the proliferation of OC simultaneously.

Objective To investigate the risk factors of worsening renal function (WRF) in patients with chronic heart failure ( CHF) and WRF influence on prognosis. Methods A case-control study were undertaken to analyze independent risk factor statistically related to incidence of WRF, and to assess the influence of WRF on prognosis. Results The independent predictors of WRF were creatinine level at admission (OR 2.248,95% CI 1.088-4.647, P = 0.029) and NYHA class on admission ( OR 2.485, 95% CI 1.3854. 459, P = 0.002). The mortality of patient with WRF was obviously higher than that of control group during hospitalization( OR 3. 824,95% CI 2. 452-5. 637 ,P ＜0.015). Conclusions WRF is a common complication among patients hospitalized for CHF, and is obviously associated with mortality during hospitalization. Higher creatinine level and weak heart function are independent risk factors for incidence of WRF of patients with CHF.

Objective To explore the effect of mefformin on glucose metabolism of rat myoblast with high fat environment.Methods The skeletal muscles of suckling Wister rats were subjected to primary culture.The myoblasts of passage 5 were divided into 5 groups:The control group was cultured in DMEM with 0.5％ BSA for 12 h.The high-fat group was exposed to 0.3 mmol/L palmitic acid for 12 h.On the basis of high-fat treatment,three intervention groups were added with 2.5,5.0 and 7.5 μg/ml metformin,respectively,for additional 24 h.Isotope tracer method was conducted to show the influence on 2-dexoy-D-[3H]glucose uptake of rat myoblast.Results With the increasing concentration of mefformin,[3H]-G uptake elevated [ ( 1.83 ± 0.34) 10-2pmd/( min · g) vs (2.33 ± 0.47 ) 10-2 pmd/( min · g),P ＜ 0.05 ],and the group of 7.5 μg/ml metformin uptakes the most.Conclusions Metformin can upregulate the glucose-uptake in rat myoblasts under the environment of high fat,and it shows a dose-dependent relationship.

ObjectiveTo study the effect of Ghrelin on activation of UCP3 and phosphorylation of ACC under the high fat environment in rat myoblast,and to support the study on prevention of type 2 diabetes.MethodsThe rat myoblast were exposed to 0.3 mmol/L palmitic acid for 12 h,at the same time,10-11 mol/L,10-9 mol/L,10-7 mol/L Ghrelin were added.The expression of UCP3 mRNA was determined by RT-PCR.The protein levels of UCP3 and p-ACC were measured by western blotting.ResultsCompared with the control group,UCP3 mRNA and the protein levels of UCP3 and p-ACC were obviously decreased in 0.3 mmol/L PA group(UCP3 mRNA:P =0.000,UCP3 protein levels:P =0.000,p-ACC protein levels:P =0.003).Compared with the 0.3 mmol/L PA group,with the increasing concentration of Ghrelin,UCP3 mRNA and the protein levels of UCP3 and p-ACC were elevated.The effects of 10-7 mol/L Ghrelin were significant(UCP3 mRNA:P =0.017,UCP3 protein levels:P =0.000,p-ACC protein levels:P =0.007).ConclusionsGhrelin could enhance activation of UCP3 and phosphorylation of ACC under high fat environment in rat myoblast.

OBJECTIVE: To evaluate the protective effects of oral administration of D-methionine tablets on noise-induced hearing impairment. METHOD: Two hundred and three volunteers were recruited and randomly divided into two groups: experimental group (n= 113) and control group (n=90). The subjects received oral administration of D-methionine tablets in the experimental group and placebo in the control group before noise exposure. Routine audiometric evaluation and ABR testing were performed and recorded before and after noise exposure. The statistical analysis was carried out with SPSS 11.0. RESULT: There were no differences in auditory threshold and I-V interpeak latency pre-noise exposure (P>0.05), however, there were statistically significant differences between two groups 1 d, 7 d after noise exposure (P<0.01 and P<0.05). In-respective-group, there were statistically significant differences between before and 1 d after noise exposure (P<0.05 and P<0.01), however, no difference was noted between before and 7 d after noise exposure in the experimental group (P>0.05). CONCLUSION The protective effects of D-methionine tablets were prominent on the noise-induced hearing impairment. Further studies regarding the optimal time of D-methionine administration will be recommended in the future.
