It is a challenging and important project to prolong the in vivo half life of protein and peptide drugs by physicochemical methods without new molecular entities generation. Protein crystallization provides a new strategy for improving the stability and in vivo delivery of these drugs. We show here that recombinant human interferon-alpha (rhIFN) can form spherical crystals. The physical and chemical features of the crystals were characterized, and drug dissolution was determined in vitro. The pharmacokinetics of crystallized interferon after sc injection in rabbit at 1.5 x 10(7) U x kg(-1) was compared to that of soluble form. The crystals were characterized as mono-dispersed spheres, with yield of > 80%, mean diameter size of about 16 microm and crystallinity of 23.2%. The in vitro dissolution behavior of crystallized rhIFN was featured as low initial burst release (21% within the first 2 h) and prolonged cumulative dissolution time up to 72 h without biological potency lost. After sc administration of soluble and crystallized interferon in rabbits, the peak time (T(max)) and half life (t1/2) were prolonged from (1.80 +/- 0.45) h and (1.35 +/- 0.35) h to (13.20 +/- 2.68) h and (10.68 +/- 1.97) h, respectively. The corresponding peak concentration decreased from (1 411.10 +/- 575.28) U x mL(-1) to (721.37 +/- 206.55) U x mL(-1). PK/PD analysis indicated that (96.87 +/- 20.30) % of relative bioavailability was obtained. The research results of this work will provide important academic value and application prospect for improving clinical therapeutic effect and development of biomacromolecules delivery system for protein and peptide drugs.

Objective To evaluate the protective effects of the ethanol extract and fractions from Polygonatum odoratum on renal lesion in diabetic rats. Methods An experimental diabetic rat model was successfully induced by one ip injection of streptozotocin (STZ) at a dose of 60 mg/kg. Diabetic rats were ig administrated the ethanol extract or fractions for 80 d. Serum levels of creatinine (Cr), urea (Ur), glycosylation hemoglobin (GHb), renal advanced glycation end products (AGEs), and urinary albumin (UAL) excretion rate were determined by biochemical methods. Glomerular volume and renal pathological changes were observed by optic microscope. Results Treatments with the ethanol extract and chloroform fraction decreased the levels of GHb and UAL excretion rate, and inhibited renal AGEs formation and renal pathological changes in STZ-induced diabetic rats. Conclusion The ethanol extract and chloroform fraction have protective effects on renal lesion in diabetic rats, which might be related to inhibiting AGEs formation.

Objective To investigate the relationship between body mass index (BMI) and health-related quality of life (HRQOL) in the adult Chinese population.Methods Data of 21 108 adults was collected from a cross-sectional survey performed in 9 provinces of China (Jiangsu,Anhui,Gansu,Qinghai,Fujian,Beijing,Jilin,Jiangxi and Henan province).Rank sum test was used to compare HRQOL with different BMI category.Multiple logistic regression analysis was used to assess the impact of different BMI category on HRQOL after adjusted for sex,age,marital,education,physical activity status,and tobacco and alcohol addiction.Results (1) For healthy subjects,the overweight BMI group had the highest HRQOL score in the physical component summary (PCS) (83.69±14.09) and mental component summary (MCS)(80.29± 15.41),while the underweight group had the worst HRQOL(81.20-± 14.05,74.82± 16.41).For subjects with chronic condition,overweight had the highest H RQOL score in the PCS(74.63± 18.51),and obese group had the best HRQOL in the MCS (76.75± 18.83).The variation among healthy and chronic disease subjects was much greater than the differences among BMI category groups.(2) Compared with normal weight,data on odds ratio(ORs) of impaired HRQOL in PCS(healthy subjects OR=1.23(1.10-1.35),chronic disease subjects OR=1.48(1.20-1.82)) MCS(healthy subjects OR=1.14(1.03-1.26),chronic disease subjects OR=1.37 (1.11-1.68)) and multiple dimensions increased among underweight.ORs of impaired HRQOL in PCS and general health dimension,MCS (healthy subjects OR =0.81 (0.72-0.91),chronic disease subjects OR=0.80(0.71-0.91)) and multiple dimensions decreased among overweight.ORs of impaired HRQOL in physical functioning dimension (healthy subjects OR=1.91 (1.25-2.92),chronic disease subjects OR=1.65(1.21-2.26)) while in MCS and role emotional and mental health dimension decreased among obese.Conclusion Whatever health or chronic disease,the influence of BMI on HRQOL is similar:the HRQOL score for the underweight group is significantly lower than that for other BMI groups in PCS and MCS.Overweight and the obese people has better HRQOL in MCS,and the obese people has poor physical function.The relation above between BMI and HRQOL is more obvious in people with chronic disease.

Objective To examine the function of body mass index(BMI)as a moderator reflecting the relationship between chronic disease and health-related quality of life(HRQOL). Methods This study included 8 314 participants pooled from a general population-based cross-sectional survey that had been conducted in Beijing and 8 provinces of China(Jiangsu,Anhui,Gansu, Qinghai,Fujian,Jilin,Jiangxi,and Henan). Hierarchical multiple regression was emplayed to test the moderating effect. Results In physical component summary of SF-36,the regression coefficient of interaction on chronic disease and BMI was not significantly different(β=0.084,P=0.142),while the new ΔR2 was not significantly different (ΔR2=0.000,P=0.142) either. In mental component summary of SF-36,the interaction on chronic disease and BMI was significantly different(β=0.132, P=0.034),so as the new ΔR2(ΔR2=0.001,P=0.034). Compared to the standard regression coefficient,chronic disease had a greater negative impact on HRQOL than BMI on both physical and mental component summaries. Conclusion Our results indicated that BMI could moderate the association between chronic disease and HRQOL. The higher the BMI,the smaller negative impact of chronic disease on HRQOL in mental component summary was seen.
