Objective To observe the effect of total glucosides of peony on hypergammaglobulinemia of undifferentiated connective tissue disease(UCTD). Methods Fifty patients with UCTD were randomly divided into the treat-ment group (total glucosides of peony and hydroxychloroquine and thymosin) (n=30) and the control group (hydroxychloroquine and thymosin) (n=20). The changes between the two groups on hypergammaglobulinemia after treated for 3 months were compared. Results The two groups all had the IgG and IgA decreased, but the treatment group decreased more significantly. In addition, the treatment group had decreased RF. Conclusion Total glucosides of peony can improve the hypergammaglobulinemia of UCTD.

Objective To enhance the understanding of hemophagocytic syndrome(HPS)by analyzing the clinical manifestations, diagnosis and therapy. Methods The clinical data of 12 patients with HPS were retrospectively collected in the People's Hospital of Jiangsu Province from 2000 to 2007. The relevant literature were reviewed. Results Twelve patients were diagnosed as secondary hemophagocytic syndrome most secondary to virus and bacteria infection. Some patients condition was associated with systemic lupus erythematosus or histiocytic necrotizing lympheadenitis. All of the 12 patients had high fever, abnormal liver function and showed a decrease in the number of blood cells in a short time. After antivirus and antibiotic treatment, 11 patients'condition were improved and 1 patient died. Conclusion Hemophagocytic syndrome is not a common clinical condition but with poor prognosis. When patient presents with fever without apparent reasons and pancytopenia, bone marrow examination should be done and sometimes repeated bone marrow examinations are needed. The diagnosis of secondary haemophagocytic syndrome needs multidisciplineary cooperation. Aggressive diagnostic procedures are needed to clarify the diagnosis and prompt treatments are warranted to improve prognosis.

Objective To investigate the prevalence and risk factors of hyperuricemia (HUA) in rural residents of Gaoyou City,Jiangsu Province.Methods A total of 4504 rural residents were investigated in a cross-sectional study.Questionarre survey and physical examination were used for the stndy.Fatsing venous blood samples were collected for biochemical examination.T-test,chi-square test for multiple-group data comparison and logistic regression analysis were used for statistical analysis.Results The prevalence of HUA was 11.9％,15.7％ in male,which was significantly higher than 8.6％ in the female (P＜0.01),the risks of HUA in male was 1.98 times higher than in female.The average value of serum uric acid in this population was higher than.that of female.The prevalence of HUA in female increased with age.Non-conditional logistic regression analysis showed WHR,Cr,Tg,hypertension were the independent risk factors of male patients with HUA.Age,BMI,Cr,Tg,hypertension were independent risk factors of HUA in female.Conclusion The prevalence of HUA can be affected by age and sex.Weight control,keeping blood pressure and blood lipid profiles in normals levels are important for the prevention of HUA.

Objective To study the expression of Adiponectin (AD) and its receptors Adiponectin receptor 1 (Adipo R1) and Adipo R2 in the synovial fluids and the synovium of rheumatoid arthritis (RA). Methods ELISA was used to determine the levels of AD in 23 RA and 23 osteoarthritis (OA) patients. Real-time PCR and Western blot techniques were employed to study the expression of AD, AdipoR1 and AdipoR2 in the synovium of 10 RA and OA patients. Results It was observed that approximately twice more adiponeetin in the synovial fluids of patients with RA than with OA. Adiponectin and AdipoR1, but not AdipoR2 mRNA, were significantly expressed in synovium of RA patients in comparison with OA. Adiponectin and AdipoR1 protein were wuch more expressed in synovium from RA than those from OA. Conclusion High expression of Adiponectin and AdipoRl is likely to contribute to the formation of inflammatory joints in RA.

Objective To introduce a practical high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)method for the detection of seven growth hormone-releasing peptides (GHRPs)including GHRP-1,GHRP-2,GHRP-4,GHRP-5,GHRP-6,Hexarelin and Alexamorelin and two growth hormone secretagogues(GHS)including anamorelin and ipamorelin,and study the stability of these nine substances in the human urine.Method The urine samples were purified and extracted by a solid phase extraction procedure using Oasis(R) WCX column.The urine was first centrifuged and taken out 1 mL into a small column,cleaned by 5％ NH4OH and 20％ CH3CN respectively,eluated using the mixture of water and acetomitrile(1/3)with 2％ formic acid,blow-dried in the nitrogen at 35℃ and finally redissolved to be injected into the LC-MS/MS.Result The limits of detection were between 0.01～0.5 ng/mL accordingly.The spiked recoveries at the low concentration(1 ng/mL),medium concentration(2 ng/mL)and high concentration(10 ng/mL)ranged between 40％ and 76％.The intra-and interday precisions of the target substances at these three concentrations were all less than 15％.The indoor temperature,refrigeration condition and multigelation were observed to have significant impact on the anamorelin,GHRP-2,GHRP-4 and GHRP-5.Conclusion The method established in this study is simple,and its specificity and sensitivity meets the international standard and technical documents for laboratories set up by the Wworld Anti-Doping Agency.It has been applied in our routine work.Multigelation should be avoided in the transport,detection and long-term laboratory storage of urine samples.
