This article reviewed the advances in studies on intestinal absorption characteristics of zinc and possible mechanisms.It has set a foundation for elucidating important functions of zinc absorption in maintaining zinc homeostasis in the body of animals.

Objective To determine the reversal effect of psoralen on multidrug resistance (MDR) in the harringtonine (HT)-resistant leukemic cell line HL60/HT. Method The modulating effect of psoralen on MDR in HL60 and HL60/HT cells were determined by the measurement of cell growth and viability via MTT assay. High performance liquid chromatography(HPLC) was used to analyze intracellular HT concentrations in HL60/HT and HL60 cells treated with psoralen. Result Psoralen from 1 to 20 μmol/L could reduce the value of IC50 to HT and enhance the accumulation of HT in HL60/HT cells. Conclusion Psoralen can reverse MDR of HL60/HT cells and is a potential modulator of MDR.

Arsenic trioxide (As2O3)is the main component of traditional Chinese medicine arsenic,which was initially used in the treatment of blood system diseases.In recent years,studies have found that it also has a good effect on a variety of solid tumors,especially gastric cancer.It has been confirmed that As2O3 can inhibit proliferation and metastasis of gastric cancer cells,induce apoptosis and protective autophagy,inhibite lymphatic formation and angiogenesis,affect the expression of telomere-related proteins in gastric cancer cells.

Objective To study the relationship between serum homocysteine level and acute type 2 diabetes mellitus complicated with cerebral infarction.Methods Patients were divided into three groups:acute diabetic cerebral infarction group including 87 patients,diabetes mellitus including 72 patients and control group including 67 healthy persons.The HCY,folic acid,VitB12 and serum lipid were determined.The data was analyzed and the relationship was discussed.Results The level of HCY in diabetic cerebral infarction group[(15.7 ±9.7)nmol/L]was much higher than that in the other two groups[(11.9±7.2)nmol/L and(13.5±6.1)nmol/L].Conclusion HCY maybe participate in occurrence and development of diabetes and pathological changes of blood vessels.It was an independent risk factor of acute cerebral infarction.

Docetaxel and vinorelbine, which were plant alkaloids, had showed the good activities as chemotherapy of breast cancer. Combination chemotherapy with docetaxel and vinorelbine had drawn more and more attention. This papers reviewed the docetaxel/vinorelbine combination treatment of breast cancer.

Objective To evaluatethe application value of APACHE Ⅱ on the prognoses in prediction of pin hole multi-directional intracranial hematoma aspiration to cure severe cerebral hemorrhage.Methods APACHE Ⅱ scoring system was conducted in randomly collected 58 severe cerebral hemorrhage patients' data (30 patients underwent surgical treatment,28 patients underwent conservative treatment)to evaluate the disease severity,prognosis and effect of the pin hole multi-directional intracranial hematoma aspiration.Results The APACHE Ⅱ score of treatment group on the first day was 28.00 ± 1.92 and the predicted mortality was 0.86 ±0.03.The score was decreased obviously on the tenth day(8.20 ± 0.76)and the predicted mortality was 0.57 ± 0.05.The actual mortality was 33.33％.Conclusion APACHE Ⅱ scoring system is suitable for judging the disease severity and predicting the prognosis of severe cerebral hemorrhage patients,it proves that surgical treatment effect of the pin hole multi-directional intracranial hematoma aspiration is remarkable.

Objective To investigate androgen receptor (AR) expression in triple negative breast cancer(TNBC) patients and its predictive value for clinical outcomes.Methods Five hundred and sixty-eight primary breast cancer patients who received surgery treatment from January 2008 to January 2010 were included in this study.Tissue sections of surgical resection specimens were underwent estrogen receptor (ER),progesterone receptor (PR),and human epidermal growth factor receptor 2 (HER2) immunohisto chemical staining,according to the judgment for triple negative breast cancer and non triple negative breast cancer.Data on age,family history,menstruation,tumor size,tumor stage,tumor grade,pathological type and lymph node metastasis were collected for analysis.Immunohistochemical analysis of AR was done in tissue sections of triple negative breast cancer patients,Kaplan-Meier method was used to compare survival between AR(+) and AR(-) groups,and Log-rank method was used to determine the association between AR-positive expression and 5-year overall survival as well as disease free survival.Results Among 568 breast cancer patients,174 (30.6％)TNBC patients were identified,including 84 patiens with AR (-) expression and 90 patients with AR (+) expression.During 5 years' follow-up,reccurrence rate was 35.7％ (30/84) in AR (-) group and 20.0％ (18/90) in AR(+) group;5-year overall survival rate was 73.8％ in AR(-) group and 81.1％ in AR(+) group.There was no significant association between AR(+) expression and 5-year death or recurrence rate,while after adjusting for age,menstruation,tumor size and lymph node metastasis,AR (+) expression was significantly associated with decreased 5-year death and recurrence rate,adjusted hazard ratio (HR) was 0.794,95CI (0.430-1.021) and 0.722,95CI (0.451-0.965) respectively.Conclusion AR (-) expression is associated with increased risk of death and recurrence and is a promising predictive marker for poor clinical outcomes.

Breast cancer is regarded as a heterogenous disease classified into different molecular subtypes,resulting in different biologic behavior and sensitivity to treatment respectively.Molecular biology typing that based gene expression profiles and biological characteristics of breast cancer can reflect the biological behavior of tumors exactly,which has important clinical significance.
