OBJECTIVE:To establish an HPLC method for determination of Emodin in Yanyan granules.METHODS:The stationary phase was Diamonsil C18(150mm? 4.6mm,5? m)column and the mobile phase was methanol-0.1% phosphoric acid(68∶ 32),with detection wavelength set at 254nm.RESULTS:Within the range of 0.26～ 3.90? g Emodin had a good linearity,and the average recovery was 96.73%(RSD=1.49%).CONCLUSION:The method is accurate,sensitive,reproducible,simple and can be used for the quality control of Yanyan granules.

Decorin( DCN) is one of the leucine-rich proteoglycan family of small molecules.It is recog-nized as a tumor suppressor gene.DCN can inhibit tumor cell proliferation and metastasis by binding and inactiva-tion of transforming growth factor beta( TGF-β) and inhibiting the expression of vascular endothelial growth fac-tor or by activating the signaling pathway that promotes cell proliferation by EGFR/MAPK/p21.it plays an impor-tant effect on tumor development,angiogenesis and metastasis.DCN is expressed in various malignant tumors,By up or down regulation,DCN can exert its anti tumor activity,as well as reducing or delaying the occurrence and development of many kinds of malignant tumor.DCN gene may be a potential target for the treatment of many kinds of malignant tumors.

Objective To investigate the clinical significance of detection of serum IL -6,IL -17, GM-CSF and TNF -αlevels in patients with rheumatoid arthritis.Methods A retrospective research was made in 79 cases with rheumatoid arthritis,and they were divided into stable period and active period,and another 40 healthy persons were chosen as control group.IL -6,IL -17,GM-CSF and TNF -αlevels were compared,and the relevance was investigated.Results CRP,ESR and DAS28 of active period [39.14 (35.81 )mg/L,41.92 (33.27)mg/L, 4.85(2.74)]were higher than those of the stable period[21.07(16.53)mg/L,29.57(25.14)mg/L,2.88(1.76)] and control group[5.92(2.80)mg/L,3.19(2.24)mg/L],the differences were statistically significant (F =7.013, 6.224,2.136,all P <0.05).Serum levels of GM-CSF,IL -6 and TNF -αof active period[33.81(26.97)pg/mL, 47.23(42.81 )pg/mL,75.35 (41.69 )pg/mL]were higher than those of control group [6.19 (5.11 )pg/mL, 4.68(5.21)pg/mL,33.18 (20.94)pg/mL]and stable period [12.81 (9.76 )pg/mL,8.46 (10.37 )pg/mL, 43.05(38.14)pg/mL],the differences were statistically significant (F =5.328,6.117,8.016,all P <0.05).And there was no significant difference in IL -17 level between the groups (F =0.776,P >0.05).No correlation was observed between IL17 and DAS28,GM-CSF and IL -6 (r =0.213,0.167,0.316,all P >0.05),TNF -αand DAS28,GM-CSF,IL -6 and IL -17 (r =0.761,0.729,0.549,0.421,all P <0.05 ),IL -6 and DAS28 and GM-CSF (r =0.648,0.626,all P <0.05),GM-CSF and DAS28 had good correlation (r =0.563,P <0.05). Conclusion IL -6,GM-CSF and TNF -αlevels were positively correlated with the progression of rheumatoid arthritis,joint detection is of great value in monitoring the disease.

BACKGROUND:Diabetes mel itus after kidney transplantation is an important metabolic complication of the transplanted organ, and seriously affects the quality of life and long-term survival rate of patients, which is a risk factor for renal al ograft dysfunction and cardiovascular disease. OBJECTIVE:To investigate the changes in fasting blood glucose and prognosis of patients who had survived more than 1 year after renal transplantation. METHODS:Total y 42 patients undergoing renal transplantation admitted at Xiantao First People’s Hospital from January 2003 to January 2013, including 7 cases of preoperative diabetes, 11 cases of impaired fasting glucose and 24 cases of normal fasting blood glucose. Fasting blood glucose levels were detected at 1, 7, 14 days and 1, 3, 6, 12 months after renal transplantation, and the survival conditions were also compared among different groups. Cox proportional hazard model was used to analyze influential factors of survival in patients undergoing renal transplantation. RESULTS AND CONCLUSION:The fasting blood glucose levels in the diabetes mel itus group were significantly higher than those in the impaired fasting glucose group and normal fasting blood glucose group before and after renal transplantation (P<0.05). The fasting blood glucose levels were increased in al the groups at 1 day after transplantation (P<0.05), and stabilized at 3 months after transplantation. The survival rate was significantly higher in the normal fasting blood glucose group than in the diabetes mel itus and impaired fasting glucose groups after renal transplantation (P<0.05). Cox proportional hazard model analysis showed that preoperative fasting blood glucose, age, postoperative tumor and infection were the independent risk factors for death in patients undergoing renal transplantation, among which, postoperative tumor led to the highest death risk ratio that was 2.376. Taken together, preoperative diabetes mel itus has some impacts on renal recipients who survive more than 1 year fol owing transplantation, but postoperative diabetes mel itus had no influence on the survival rate of the patients.

The research on the clinical characteristic and epidemiology in Henoch-Schonlein purpara of children indicates that genetic factors are closely connected with the disease and pathological process.In recent years,molecular biology studies show that C1 GALT1 gene,IL gene,vasomotor and endothelial function regulation genes,angiotensin-converting enzyme gene,angiotensinogen gene,MEFV gene and so on,which have aberrant IgAl giycosylation,are closely related with pathogenesis of Henoch-Schonlein purpura in children.The paper reviews the progress of genetic mechanism associated with Henoch-Schonlein purpura in recent years.

As one of the chronic diseases,asthma,plays a serious impact on human daily life.Asthma in children has showed an increasing trend in recent years,but the mechanisms of asthma are not yet clear.Studies have found that store-operated calcium entry(SOCE) plays an important role in the physiological activity of the body.The enhanced SOCE activity can promote cell growth,proliferation,and migration of a variety of cell types.SOCE important molecules STIM1 and ORAI1 may be involved in the asthmatic airway occurrence of hyperresponsiveness and airway remodeling,and closely to the asthmatic development.
