Objective To investigate the auxiliary effects of huaier granule on hepatoeellular carcinoma (HCC)patients after liver transplantation.Methods Sixty HCC patients who had undergone liver transplantation from Julv 2004 to June 2006 and met the standard of UCSF were involved in this study.All patients were divided into huaier granule group(n=20),chemotherapy group(n=15),huaier granule+chemotherapy group (n=15)and control group(n=10).The white blood cell count,liver function,cell immunity and immunologieal reiection were detected.The 1-year tumor recurrence rate wag calculated.Results The white blood cell counts in chemotherapy group 1,3,and 6 months after treatment were significantly lower than that before treatment (F=62.053,58.472,49.807,P<0.05).The changes of white blood cell counts of the other 3 groups before and aftertreatment were small.The difference on the white blood cell counts of the 4 groups had no statistical 8ignincanee(F=102.361,113.412,87.572,P<0.05).The NK activity,CD4+/CD8+ ratio,IL-2 level in huaier granule group and huaier granule+chemotherapy group 1,3,6 months after treatment were significantly higher than those before treatment,and were significantly higher than those in chemotherapy group and control group(P<0.05).No immunological rejection occurred in all the groups.Two patients in each group had recurrence and metastasis of HCC within 1 year after the treatment.and the incidence in control group was higher than the other 3 groups(P<0.05). Conclusions Humer granule can increase the white blood cell count which is decreased after chemotherapy,impmve cellular immunity,and effectively suppress the recurrence and metastasis of HCC at the first year after operation.

As a depot drug delivery system, injectable polylactide-polyglycolide (PLGA) sustained-release microspheres have been successfully used to treat many diseases since the first microsphere product Lupron depot was approved for marketing in the United States in 1989. It has the ability of long-term release in the body for several days to several months, which can not only reduce the times of administration, but also reduce the drug blood concentration fluctuations, significantly improve the safety and patient compliance.

In recent years, layer-by-layer self-assembly (LbL) has developed rapidly. It has been widely used in various industries such as medicine and metallurgy because of its simplicity, flexibility and controllability. In the study of drug delivery system, hollow microcapsules constructed by LbL method as drug carrier have great advantages in drug release, circulation

The efficient and safe delivery of drugs to the therapeutic site through the biofilm has traditionally been a difficult and hot topic in the field of drug delivery. In recent years, alkyl polyglycoside (APG) have become ideal penetration enhancers for drug delivery systems because of their high permeability, good safety and biodegradability, which has attracted wide attention of domestic and foreign researchers. In this paper, the physical and chemical properties, characteristics, action mechanism and application of APG in drug delivery system are reviewed, and its application prospect in drug delivery system is prospected.

OBJECTIVETo investigate the protective effects of oxymatrine on chronic heart failure induced by isoproterenol (ISO) and to observe its effects on ADMA metabolism pathway in ISO-induced chronic heart failure in rats.
METHODMale Sprague-Dawley rats were given oxymatrine (100,50 mg kg-1) orally for 14 days. Heart failure was induced in rats by subcutaneous injection of isoproterenol (5 mg kg-1 d-1 ) at the 8th day for 1 week. Serum parameters, haemodynamic parameters, Heart weight, and histopathological variables were analysed. Expression of protein levels were measured by Western blot.
RESULTOxymatrine (100,50 mg kg-1) significantly attenuated serum content of cTn I, improved left ventricle systolic and diastolic function and left ventricular remodeling, reduced the ISO-induced myocardial pathological changes compared with ISO group. In addition, oxymatrine (100,50 mg kg-1) significantly reduced serum level of ADMA (P <0. 01), normalize the reduced dimethylarginine dimethylaminohydrolase 2 (DDAH2) expression (P <0. 01) , but had no effect on the isoproterenol-induced upregulated protein arginine methyltransferases 1 expression.
CONCLUSIONOxymatrine could ameliorate the experimental ventricular remodeling in ISO-induced chronic heart failure in rats and the mechanism involved in reducing serum content of ADMA and increased DDAH2 expression.

OBJECTIVETo study the mechanism of the apoptosis induced by N-[4-hydroxyphenyl] retinamide (4-HPR) in bladder cancer cell line T24, and the involvement of DNA damage and repair.
METHODST24 cells were treated with 4-HPR at the concentration of 2.5, 5.0 and 10.0 micromol/L, and the cell grow inhibition was measured by cell counting assay. The fluorescent intensity of reactive oxygen species (ROS) was determined by spectrofluorometer. The apoptosis was measured by flow cytometry and DNA fragment assay. The expression of XRCC1 protein and activation of caspase-3 were detected by Western blot.
RESULTS4-HPR induced apoptosis in T24 cell. A dose-dependent increase in the percentage of apoptosis cells was observed (1.8%, 4.0% and 10.5% respectively at 2.5, 5.0, 10.0 micromol/L 4HPR). In the meantime, ROS level in the cell was increased (peaked at 3 fold). It also caused down-regulation of the expression of XRCC1, and activation of caspase-3. Vitamin C effectively inhibited ROS rise induced by 4-HPR, and also partially inhibited cell growth, apoptosis, and down-regulation of the expression of XRCC1.
CONCLUSIONThe generation of ROS and DNA damage may be the major mechanism of the apoptosis of bladder cancer cell line T24 induced by 4-HPR.

OBJECTIVE:
To study the influence of dasatinib treatment on body height in children with acute myeloid leukemia (AML).
METHODS:
A retrospective analysis was performed for the clinical data of 86 AML children aged <17 years. According to the treatment regimen, these children were divided into a conventional chemotherapy group and a dasatinib chemotherapy group. The 57 children in the conventional chemotherapy group were given conventional chemotherapy drugs without tyrosine kinase inhibitor, and the 29 children in the dasatinib chemotherapy group were given conventional chemotherapy drugs and dasatinib. The two groups were compared in terms of height standard deviation score (HtSDS) at the beginning of treatment and after treatment, as well as the change in HtSDS after 1 and 2 years of treatment.
RESULTS:
There was no significant difference in HtSDS between the conventional and dasatinib chemotherapy groups before treatment. Within the first two years of treatment, the dasatinib chemotherapy group had a similar change trend of HtSDS as the conventional chemotherapy group. Four children in the dasatinib chemotherapy group reached the final adult height during follow-up, which was significantly lower than the target height (P=0.044). In the conventional chemotherapy group, there was no significant difference between final adult height and target height. In the dasatinib chemotherapy group, the children in adolescence had a significant change in HtSDS after treatment (P=0.032).
CONCLUSIONS
Dasatinib treatment may affect the final height of children with AML, and the use of dasatinib after the beginning of adolescence may lead to growth disorder, but dasatinib treatment has little effect on body height in the short-term treatment.

OBJECTIVETo investigate maternal-fetal transmission at human bocavirus (HBoV).
METHODSIgG antibody to HBoV in serum samples of 316 mothers were determined with ELISA and HBoV DNA was determined with real time PCR in the sera of the mothers and their infants.
RESULTSHBoV-IgG was positive in 40.20 percent (127/316) of the mothers, while it was positive in 29.43 percent (93/316) of the cord blood specimens of the infants. The difference between the two groups was significant (X2=8.12, P less than 0.005); 93 samples of both the mothers and the infants were positive for HBoV-IgG.
CONCLUSIONHBoV-IgG can cross the placenta to the fetuses through placenta. Further study is needed to answer the question whether vertical maternal-fetal transmission occurs.
