Objective To observe the therapeutic effect of Shenluo'an Decoction(SD) for the treatment of obese patients with early diabetic nephropathy and to explore the possible mechanism.Methods A total of 68 obese patients with early diabetic nephropathy were randomly assigned into control group and treatment group,34 cases in each group.Both groups were given conventional western medicine treatment including lifestyle regulation,dietary control,and medicine for lowering blood pressure,blood glucose and blood lipids.Additionally,the control group was given oral use of Irbesartan,and the treatment group was given oral use of SD combined with Irbesartan.Before and after treatment,we observed the traditional Chinese medical syndrome scores,body mass index(BMI),blood levels of cystatin C (Cys C),β2-microglobumin(β2-MG),homocysteine (Hcy) and fasting blood glucose (FBG),and urine parameters of urinary monocyte chemoattractant protein-1 / urinary creatinine (UMCP-1/UCR),urinary factor of regulated on activation in normal T cell expressed and secreted / urinary creatinine (URANTES/UCR),urinary albumin-to-creatinine ratio (UACR) and urinary albumin excretion ratio (UAER) before treatment and after treatment for 16 weeks.After treatment,the clinical efficacy and safety were also evaluated.Results (1) During the treatment,5 cases were dropped out,and a total of 63 cases (32 from the treatment group and 31 from the control group) completed the experiment.(2) The total effective rate of the treatment group(90.6％) was significantly higher than that of the control group(67.7％),the difference being significant(P ＜ 0.05).(3)BMI of the two groups after treatment was significantly lower than that before treatment (P ＜ 0.05).(4) After treatment,the traditional Chinese medical syndrome scores,blood parameters (Cys C,β2-MG,Hcy,FBG) and urine parameters (UMCP-1/UCR,URANTES/UCR,UACR,UAER) in the treatment group were decreased as compared with those before treatment and those in the control group after treatment(P ＜0.05).(5) A positive correlation was present among the parameters of UMCP-1/UCR,URANTES/UCR,UACR and UAER.(6) No abnormal changes took place in the blood and stool routine examination,hepatic function,or electrocardiography of the 63 cases.Conclusion SD combined with western medicine exerts certain therapeutic effect for obese patients with early diabetic nephropathy,and is effective on relieving clinical symptoms anddecreasing BMI,Cys C,β2-MG,UACR,UAER,UMCP-1 and URANTES.Its mechanism is probably related with the inhibition of chronic renal inflammation.

OBJECTIVE: Osteoblasts are essential for osteogenesis and bone metabolism, the in vitro culture of osteoblasts is the foundation for studies on bone metabolism and osteogenetic mechanism. Therefore, it is of great significance to study the related factors affecting it.DATA SOURCES: Related literature about the influencing factors of in vitro culture of osteoblasts were searched for in Medline from January 1980 to December 2004 with retrieval words of "osteoblasts, culture in vitro, in fluencing factors", with the language limited to English. Meanwhile, it was also searched in the CBM between January 1995 and December 2004 with the retrieval words of "osteoblasts, in vitro culture, influencing factors",with the language of the articles limited to Chinese.STUDY SELECTION: After preliminary examination, literature that met the need of this study was searched for the full text. Inclusion criteria: Factors influencing the in vitro culture of osteoblasts included ① physical factors; ② microelements; ③ growth factors; and ④ hormones.Reviews were removed from this study because of summary or repetitive research.DATA EXTRACTION: A total of 105 articles related to the influencing factors of the in vitrocul ture of osteoblasts were obtained, articles of repetitive and similar researchwere removed; thereby 17 articles were included in the study.DATA SYNTHESIS: ① Physical factors: Ionizing radiation, microgravity,external force, and oxygen pressure. ② Microelements: microelement deficiency would hinder the skeletal growth, or even lead to malformation. Osteoblastic proliferation is closely related to some microelements, mainly including zinc, aluminum, fluorine, copper, manganese, calcium, and magnesium. ③ Growth factors closely related to osteogenesis mainly consist of bone morphogenetic protein, platelet-derived growth factor, fibroblast growth factor, transforming growth factor-beta, insulin like growth factor,and osteogenic growth peptide (OGP). ④ Hormones capable of promoting the proliferation and differentiation are growth hormone, estrogen, thyroxine, parathyroxine, and glucocorticosteroid.CONCLUSION: Multiple factors are involved in the in vitro culture of osteoblasts. It is helpful to understand these influencing factors to seek an effective way for the in vitro culture ofosteoblasts that is applied in tissue engineering.

Objective To observe the changes of β-catenin expression in human skin fibroblasts (HSFs) after induced by oxidative stress, and to explore its possible roles in oxidative stress-induced premature senescence (SIPS) of HSFs. Methods Fibroblasts were isolated from the foreskin of a child and subjected to a primary culture. The fibroblasts of second to fourth passage were treated with various concentrations of H2O2 for 2 hours to establish an optimized model of stress-induced premature senescence, β-galactosidase assay kit was used to detect the activity of β-galactosidase in H2O2rinduced HSFs, RT-PCR and Western blot to measure the mRNA and protein expressions of β-catenin in control and senescent HSFs. Results Premature senescence of HSFs could be induced by the treatment with H2O2 of 150 μmol/L for 2 hours. The proportion of β-galactosidase-positive cells was (2.97 ± 0.25)% in control HSFs and (37.67 ± 1.53)% in senescent HSFs (P< 0.01). A significant increase was observed in the β-catenin/GAPDH protein ratio and β-catenin/GAPDH mRNA ratio in control HSFs compared with the senescent HSFs (0.62 ± 0.03 vs. 0.31 ± 0.01, t = 14.97, P < 0.01; 0.59 ± 0.04 vs. 0.29 ± 0.30, t = 10.06, P < 0.01). Conclusions The two-hour treatment with H2O2 of 150 μmol/L could induce the premature senescence of HSFs, and there is a notable decrease in the expression of β-catenin in prematurely senescent HSFs induced by oxidative stress, implying that β-catenin is an important target gene for the regulation of skin aging.
