Objective To explore the effect of transforming growth factor ?_1 (TGF-?_1) on expression of paxillin(Pax) in human kidney proximal tubular epithelial cell line (HKC cells) in different phases. Methods HKC cells cultured in vitro were divided into four groups at random. Control group(C group): HKC cells were cultured with serum free medium (FSM), and TGF-?_1-treated groups (T1, T2, T3 group): HKC cells were cultured with FSM containing 10ng/ml TGF-?_1. In the latter groups, duration of treatment varied as follows: T1 group for 24h, T2 group for 48h, T3 group for 72h. The proliferation of HKC cells induced by TGF-?_1 was assessed by MTT and the expression of Pax was determined. The gene expression of Pax was determined by reverse transcripton polymerase chain reaction (RT-PCR) and the protein expression of Pax was assessed by immunohistochemical staining and Western blot. Results TGF-?_1 could induce the proliferation of HKC cells in a time-dependent manner. In C group there was expression of Pax mRNA and protein in HKC cells. The expression of Pax mRNA and protein in HKC cells was positive in all the T groups, especially in T2 group and T3 group they were significantly increased compared with T1 group (P

Chinese Journal of Primary Medicine and Pharmacy 2009;16(1):20-21
Objective To explore the factors associated with infections in children with leukemia after chem-otherapy. Methods Clinical data of fifty-six children with leukemia, who infected after chemotherapy were reviewed with infection characteristics and some related factors. Results The infection rates were 27% in upper airway,37% in lower upper airway,12% in oral cavity,5% in gastrointestinal tract,3% in perianal abscess,7% in urinary sys-tem,5% in scpficaemia and 2% in ofitis media. Most infection happened from five to ten days after chemotherapy,and the infection rates varied with chemotherapy scheme. The persistence time of infection were (8.5±2.2) days in the children with the numbers of neutrophil below 0.5×109/L and (3.5±1.4) days in those above 0.5×109/L with significant difference(P <0.01). Conclusions After chemotherapy,the children had more chances to be infected. To be more exact, the /nfection was more common observed in respiratory tract, next in gastrointestinal tract. And the stronger the medicine used the number of heterophil granulocyte dropped much more ,the infection happened more easily.

5.Diabetes mellitus and primary liver cancer: risk factor or real cause?
Journal of Clinical Hepatology 2017;33(4):757-762
With an increasing prevalence all over the world,diabetes mellitus is considered as a potential cause of liver cancer in patients with non-viral hepatitis.Whether diabetes mellitus is the cause of liver cancer and related pathogenesis remain unknown.The article reviews recent large-sample cohort studies and confirms that diabetes mellitus increases the incidence rate of liver cancer and affects its prognosis.This article also investigates the association of hepatitis C,obesity,and nonalcoholic fatty liver disease with diabetes mellitus and liver cancer and finds that insulin resistance and activation of chronic inflammatory factors may be involved in the generation and proliferation of cancer cells.This article elaborates on the influence of anti-insulin resistance drugs on the development and progression of liver cancer and points out that diabetes mellitus may be the cause of liver cancer.Effective control of insulin resistance can help to reduce the development and progression of diabetes-associated liver cancer.
