Objective To investigate the effects of rosiglitazone (RSG) on glycemia and ?-cell function in type 2 diabetic patients. Mothods Open-label and self-match trial was carried out. 31 cases of type 2 diabetic patients were divided into RSG monotherapy group (n=13), RSG plus metformin group (n=9), and RSG plus sulphonylureas group. All the patients received treatment for 12 weeks. Weight, body mass index, FBG, FINS, blood pressure, TG, Tch, HDL, LDL, ALT, AST and TBIL were determined before and after therapy. The insulin resistance (HOMA-IR) and ?-cell function (HOMA-?) of the patients were evaluated using homeostasis model assessment (HOMA). Results Compared with before treatment, there was a significant improvement in FBG, FINS, HOMA-? and HOMA-IR in all the patients after treatment (FBG 8.89?2.49mmol/L, FINS 17.89?5.78mU/L, HOMA-? 79.75?41.28,HOMA-IR 7.15?3.40 vs FBG 7.27?2.26mmol/L, FINS 14.33?3.82mU/L,HOMA-? 120.84?140.66,HOMA-IR 4.63?1.81, respectively,P

Objective To explore the role of CD4+CD25+CD127low/-regulatory T cells (Tregs) in the pathogenesis of psoriasis vulgaris(PV). Methods Flow cytometry analysis was used to detect the amount of Tregs in peripheral blood and ELISA to test the levels of IL-10 and TGF-β1 in blood serum; the suppressive function of Tregs on autologous CD4+CD25-T cells was determined by MTT method. Results No significant difference was found in the proportion of Tregs in PV patients and healthy controls(P>0.05). There was a diminished suppression of Tregs from patients on autologous CD4+CD25- responder T cell proliferation in PV patients when compared with that in controls (P < 0.01). The serum level of IL-10 in patients was lower than that in controls (P < 0.01) while that of TGF-β1 in PV patients was significantly higher than that in controls(P < 0.01). Conclusion Abnormal function of Tregs and low secretion of IL-10 in PV patients might be related to the pathogenesis of psoriasis.

Objective To find out a relatively accurate teenagers' age estimation method.Method 233 cases were collected with emphasis to their type of crime, the intervals from commitment of the crime to age assessment, and the differences between self - reported and appraised age. By regression equation (method 1), CHN evaluation (method 2) and comprehensive method designed by the authors (method 3), 130 male teenagers whose osteophiph-ysis hadn' t been closed were compared and analyzed, statistically andyzed by Chi square test. Results The analysis showed : (1) 72.10% cases were of plundering and robbing type. (2) The intervals from commitment of the crime to age assessment in 75.10% cases were less than six months. (3) Self- reported ages in 60.73% cases were less than appraised age. (4) The accordance rate between method 1, method 2 to method 3 was 90.77% and 83.08% respectively. Conclusion The age estimation on living body should be performed as soon as possible after commitment of the case, and method 1 seems to be more accurate than method 2 in estimating 18 years-old person,and the method designed by us should be better than the other two.

Objective We tried to investigate the nutritional status and related factors in patients undergoing allogenetic hematopoietic stem cell transplantation.Methods A total of 75 patients were recruited from a class-three hospital in Suzhou.They were investigated with a basic information questionnaire and the Patient-Generated-Subjective Global Assessment (PG-SGA).The related factors influencing nutritional status were analyzed.Results The PAB level began to rise since conditioningregimen,and it rose to the highest level in the second week,then began to decline.The weight and the BMI had been declining in the four weeks since conditioning regimen.29.33％ of the patients were malnourished,the scored PG-SGA was (5.60±4.96),the percentage of patients with dietary problems was 33.3％ before conditioning regimen; 85.33％ of the patients were malnourished,the scored PG-SGA was (19.26±7.18),the percentage of patients with dietary problems was 93.2％ in the second week since conditioning regimen; 85.33％ of the patients were malnourished,the scored PG-SGA was (12.95±6.19),the percentage of patients with dietary problems was 75.8％ in the fourth week; Age is the main factor affecting the patients' albumin level in the second week.Conclusions The nutritional status of patients deteriorated and the percentage of patients with malnutrition increased during allogeneic hematopoietic stem cell transplantation.Clinical staff should pay attention to the assessment of nutritional status,and give a reasonable nutritional support when necessary.

AIM:To investigate atrial natriuretic peptide(ANP) circadian in the encapsulated human ANP(hANP) cDNA transfected cells,to alter the ANP circadian by artificial control to achieve the objective of effectively treat hypertension or congestive heart failure(CHF). METHODS:ANP cDNA was transfected into Chinese hamster ovary(CHO) cells,which were encapsulated in polycarprolactone(PCL) tubes.The longterm survival of transfected CHO cells and the levels of ANP secreted were detected.Circadian rhythm of ANP secreted by encapsulated transfected cells was also studied,which was regulated by melatonin. RESULTS:During culturing,the ANP level secreted by transfected CHO cells in 2 mL of culture medium within 24 hours could reach 210.3 ng/L in a 20 mm-long and 2 mm-diameter PCL tube.The section of ANP displayed a circadian variation:higher in daytime,but lower at night.The acrophase of circadian rhythm was 4:15 but could be shifted to 7:55 after melatonin management. CONCLUSION:ANP cDNA transfected CHO cells that encapsulated into PCL tube can secret ANP,which might be suitable for the future implantation into human body.Our research provides a new approach in the treatment of hypertension and CHF by ANP.
