Objective To study the pharmacokinetics and pharmacodynamics of recombinant human insulin preparations SciLin TM R and Humulin (R) R,and to evaluate their bioequivalence in Chinese healthy volunteers.Methods In this positive control,single dose,open label,randomized cross-over study,20 male healthy volunteers were recruited from March to October 2007,and tested on two experimental days with an interval of 7-14 days.The volunteers were divided into two groups with a random number table,one group was injected with SciLin TMR for the first time and Humulin (R) R for the second time,the other group was injected with the opposite.The pharmacokinetics and pharmacodynamic properties were evaluated by euglycemic glucose clamp study.Results Time to peak concentration [Tmax,(105.8 ± 19.1) minutes vs.(103.5 ± 18.1) minutes,P =0.389) and time to maximum glucose infusion rate [TGIRmax,(132.8 ± 16.8) minutes vs.(132.8 ± 18.6) minutes,P =0.697] for SciLin TMR and Humulin(R) R were similar.The relative bioavailability of SciLin TMR was (102.2 ± 7.6) ％,and the relative biological effectiveness was (107.4 ± 18.8) ％.The 90％ confidence interval(CI) of peak concentration(Cmax) and area under the curve of blood glucose concentration at 0-10 hours (AUCIns 0-10) of SciLin TM R were 99.32 ％-102.62 ％ (equivalent range 70％-143 ％) and 98.98 ％-104.99 ％ (equivalent range 80％-125％),respectively;90％ CI of the maximum glucose infusion rate (GIRmax) and AUCGIR0-10 were 97.36％ ～ 103.49％ (equivalent range 70％-143％) and 98.72％-113.54％ (equivalent range 80％-125％),respectively,indicating that SciLin TMR and Humulin (R) R was bioequivalent.There was no clinically significant abnormalities in the safety indexes before and after the tests.During the trial,no hypoglycemic events,allergic reactions,or local injection adverse reaction occurred.Conclusion The studied recombinant human insulin preparation SciLin TMR may be bioequivalent as Humulin (R) R.

SUMMARY We analyzed the clinicopathological characteristics of one patient with Rhupus syndrome as-sociated nephropathy in Peking University People ’s Hospital, and reviewed the related literature .The pa-tient was a middle aged female .She developed rheumatoid arthritis first , and then manifested mild sys-temic lupus erythematosus together with positive anti-neutrophil cytoplasmic antibodies ( ANCA ) and cryoglobulinemia several years later .The renal biopsy was performed and manifested as lupus nephritis . The transmission electron microscopy revealed cryoglobulinemia associated renal damage .This report shows that the clinicopathological characteristics in patients with Rhupus syndrome associated nephropathy are complicated .The renal pathology can be used as a diagnostic tool .

Objective To evaluate the value of continuous glucose monitoring system (CGMS) in the gestational patients with impaired glucose regulation. Methods The glucose level in the subcutaneous tissue was monitored by CGMS for 3 days in 6 patients with gestational diabetes mellitus (GDM) and 6 patients with gestational impaired glucose tolerance (GIGT). The fluctuation coefficient of blood glucose, percentage of hyperglycemic time, and percentage of hypoglycemic time were calculated. Results As shown by CGMS, the fluctuation coefficient of blood glucose, mean glucose level, percentage of hyperglycemic time, percentage of hypoglycemic time, mean fasting blood glucose, and mean postprandial blood glucose (PBG) levels were not significantly different between GDM group and GIGT group (P ＞ 0. 05). The time for reaching the peak PBG level ranged 90-120minutes in both two groups (P ＞ 0. 05). No sensor-related adverse events were noted. Conclusions It is safe to apply CGMS sensor in pregnant women. The blood glucose profiles are comparable between GDM and GIGT patients by CGMS; therefore, control of blood glucose should be equally strict in patients with GIGT as those with GDM.

Objective To establish luciferase-labeled mesenchymal stem cells in vitro.Methods From May,2013 to January,2014,recombinant lentiviral vectors containing luciferase gene was transfected in to mesenchymal stem cell line C3H10T1/2.Puromycin was used to filter the cells.Western-blot and immunofluorescenceimaging were used to detect the transfection efficiency.Results Western blotting analysis showed that the size of this protein in cells expressing about 60KD.Showed that infected C3H10T1/2 cells expressing luciferase protein.I mmunofluorescence,compared with the uninfected control group,virus-infected cells group of about 100％ of the cells were positive for red fluorescence.Show that had built a good stable expression of luciferase C3H10T1/2 cells.Conclusion A monoclonal cell line stably and highly expressing luciferase is obtained with luciferase-labeled mesen chymal stem cells.

Five population groups, including farmers living in Veining (a cold hilly southern county), farmers and labourers in Shijiazhuang (a northern district), coastal fishermen in Zhoushan and "Yi" nationality farmers in Veining (where the incidence of hypertension is very low in China) were selected randomly (467 male subjects, 40-59 years old) to explore nutritional parameters-BP relationships. The results showed; (1) Pulse rate, QI and BP were lowest in Veining "Han" and "Yi" nationality groups. (2) Values of blood and urine nutritional parameters were in close accord with the diet customs of the different population groups. (3) Urine Na, Ca, Ca/Mg, urea nitrogen and serum cholesterol, total protein, albumin, uric acid were higher, while urine K was lower in hypertensives. (4) Urine Na, Na/K, Ca/ Mg and serum albumin, total protein, cholesterol, triglyceride, uric acid levels correlated positively, while K inversely with BP on multivariate stepwise regression and/or discrimination analyses. These results suggested high Na (Ca)-intake might be hypertensive, while high K(Mg)-intake an-tihypertensive, the serum protein - BP relationship could not be ascribed as a secondary effect of hemoconcentration in hypertension; a high protein intake, regardless of nature, could be hypertensionogenic; hyperlipidemia seemed to be a risk factor of hypertension, not being the secondary consequence to high BP. In designing a strategic protocol for primary prevention of hypertension, the above should be given due consideration.

Eight populations including 4 Chinese districts and 4 nationalities 484 subjects (male, 40~59 years) were conducted for exploring amino acid (22 sorts)-BP relationship by multi-variate regression and discrimination analyses. Results showed:(1)The different amino acid levels found among "Ka-zak", "Han" and "Uygur" nationalities living in one of the same Xinjiang region might be a reflection of their diverse dietary patterns; while the difference seen between "Han" and "Yi" nationalities living in one of the same Quizhou area, taking similar diet, might be due to the inherited metabolic influence. (2) The levels of aspartic and (or) glutamic acids were the the highest in the Quizhou "Han" and "Yi" groups living in cold hilly area, while other amino acids were comparatively lower, in keeping with their BP, Quetelet's indices and serum urea levels to be the lowest, tentatively denoting that the tissue metabolic turnover rate might be also lower as well in these groups. (3) The serum levels of sulfur containing amino acids in those populations taking much animal foods, were all higher, therefor ethe lower incidences of cardio-cerebro-vascular diseases seen in fishmen can not be thus wholly ascribed to the high intake of fish meat rich in sulfur containing amino acids. (4) From BP regression equations, valine, cysteine, alanine, threonine were found to be the prohypertensives while glycine, leucine, methionine and phenylalanine,the antihypertensives.
