Livin is a new member of the inhibitors of apoptosis protein(IAP) gene family. It is highly expressed in most human tumors, involved in inhibiting cell apoptosis, and closely related with tumor occurrence, development and prognosis. So Livin could be a new target for tumorous early diagnosis and cancer therapy. This paper summarizes the Livin gene molecular structure, tissue expression, biological function,and its application in cancer treatment.

OBJECTIVE:To control the drug quality risk in drug withdrawal links of hospital pharmacy,and provide reference for the application of quality risk management(QRM)in hospital pharmacy. METHODS:Drug QRM was developed in drug with-drawal links through risk identification,risk assessment,risk control,risk assessment and other steps. Using the incidence of risk factors and reusable rate of withdrawal drug as indexes,related data of before(Jul.-Dec. 2015)and after(Jan.-Jun. 2016)devel-oping QRM in our hospital were compared to evaluate the effect of drug QRM. RESULTS:Determining whether specific storage drugs kept the required storage conditions,whether the numbers of withdrawal drugs counted to minimal packaging and other 5 fac-tors were high-risk factors(the risk score of each factor>4 points);control measures were taken separately for high risk factors, then high-risk factors were reduced to acceptable levels(risk score<4 points). After developing QRM,the incidence of risk factors were reduced than before(reduce 1.35%-6.19%),reusable rate of withdrawal drug was increased(98.64% vs. 86.32%)(all P<0.05). CONCLUSIONS:Developing QRM in drug withdrawal links of hospital pharmacy can reduce the drug quality risk.

Objective To explore the relationship between single nucleotide polymorphisms (rs12953-717) of SMAD7 and susceptibility of non-small cell lung cancer (NSCLC) in Chinese Han population.Methods A single nucleotide polymorphisms (rs12953717) from SMAD7 was detected via Sequenom system in 528 NSCLC cases and 762 healthy controls.Data was statistically analyzed by unconditional Logistic regression method.Results rs12953717 had significant differences between non-small cell lung cancer patients and the controls.Compared with CC/TT (CC combined with TT) genotype,the adjusted odds ratio for the CT genotype was 4.107 (95％ CI:3.206 ～ 5.260,P =0.000 1).Smokers had a 2.004 odds ratio (95 ％ CI =1.583 ～ 2.537,P =0.000 1) of NSCLC compared with the controls.There was a 10.074-fold increased risk of NSCLC among the subjects with CT genotype and smokers.Conclusion The polymorphism of rs12953717 may have relation with risk of NSCLC.Heterozygote (CT) is a susceptibility genotype of NSCLC.Smoking is one of the risk factors of NSCLC.Smoking and CT genotype have synergistic effects on NSCLC susceptibility.

Objective To investigate the change in heat shock protein 70(HSP7O) in the brain tissue of fetal and newborn rats after prenatal hypoxic adaptation and the possible mechanism of the protective effect. Methods Twenty-two 22d pregnant Wistar rats were randomly divided into two groups: GroupⅠ(hypoxic adaptation group) and group Ⅱ(control group). The animals in group Ⅰ were placed in a tightly closed hypoxic adaptation chamber, of which the oxygen and carbon dioxide concentrations were monitored. The pregnant rats were taken out and exposed to fresh air for 5 mm when the 02 % in the chamber was reduced to 15 %, then the pregnant rats were placed back in the chamber and the above process was repeated once. The animals were then left for their natural labor. In control group the pregnant rats underwent the same process but the chamber was not tightly closed(O2 %= 21 %). Prenatal rats were delivered by cesarean section at lb. 3h, 8h, 24h, 48h, 72h, 120h and 168h after hypoxic adaptation and decapitated and brain was removed. Seven newborn rats from each group were decapitated and brain was removed for determination of HSP70 expression with immunohistochimical technique. Results No HSP7O expression was observed in the brain tissue of normal prenatal and newborn rats. HSP70 was observed in the different regions of hippocampus and cortex from 8h to 168h after hypoxic adaptation. Strongest HSP70 expression was observed in hippocampus CAl . Conclusions HSP70 plays a role in the formation of prenatal hypoxic adaptation.

Objective To examine whether the prenatal hypoxia adaptation has any protective effect on the brain of the newborn rat Methods 12 22 day pregnant Wistar rats were randomly divided into 2 groups: the control group and the treated group In the treated group the pregnant rats were placed in a tightly closed hypoxia adaptation chamber When the O 2% in the chamber dropped to 15%, the rat was taken out to breathe fresh air for 5 min then put back in the chamber This process was repeated until its natural delivery In control the chamber was not tightly closed (O 2%=21%) 40 newborn rats weighing 6 8g were selected and subjected to brain ischemia and hypoxia, Left common carotid artrey was ligated under ether anesthesia 2h after recovery from surgery the newborn rats were placed in hypoxia chamber (T=36℃?1℃,O 2%=9%)for 1 5h 24h later they were sacrificed and brain was removed for microscopic examination (optical and electron) and flow cytometry measurement Results In the treated group most newborns were normal There were a few apoptosis cells in early stage The rate of apoptosis was 2 9%, necrosis cells could hardly be seen In the control group, although most neurons were also normal but there were apoptosis cells in early, middle and late stage and even necrosis cells The rate of apoptosis was 9 51%, which was significantly different from that in the treated group Conclusions Prenatal hypoxia adaptation has protective effect on the brain of newborn rat

ve To determine the most approprite hypoxic concentration and duration for prenatal hypoxic adaptation animal experiment by exposing pregnant rats to the hypoxic air of different oxygen concentration.Methods Full-term pregnant rats( gestation time 22 days) were placed in an airtight cabin specially designed for hypoxic adaptation experiment. The rats were divided into 7 groups. The Q2 concentration in the airtight cabin was decreased from 21% (group Ⅰ as control) to 18% (group Ⅱ), 17% (group Ⅲ), 16% (group Ⅳ), 15% (group Ⅴ), 14% (group Ⅵ) and 13% (group Ⅶ) respectively. The animals were exposed to short duration of hypoxic air twice with a break of 5min breathing fresh air. The duration of the first hypoxic episode lasted 10 min (group Ⅰ ) , 5 min (group Ⅱ), 7.5min (group Ⅲ), 9.83 min (group Ⅳ), 11.5 min (group Ⅴ), 13.17 min (group Ⅵ) and 14 min (group Ⅶ) respectively. The second hypoxic episode lasted 10min, 9.33 min, 11 min, 15.17 min, 13.33 min, 17 min and 18 min respectively. Ten newborn rats (1 day after birth) randomly selected from each group were placed in a 100ml airtight bottle and the duration from the start to the time when the newborn rat stopped breathing was recorded as hypoxia surviving time. Another 10 newborn rats randomly selected from each group were decapitated and brain was removed for light and electron microscopic examination to determine the degree of neuronal damages. Results In group Ⅰ-Ⅴ the newborn rats were normal (pink skin color and good extremity movement) . In group VI 10/55 (18%) newborn rats were cyanotic with diminished extremity movement, the others were normal. In group VIII 11/52(21% ) newborn rats died, 14/ 52(27%) were cyanotic with diminished extremity movement. Neuronal damages could be seen in cyanoticnewborn rats including decreased number, swelling, apoptosis of neurons and expanded mitochondria. The hypoxia surviving time was significantly longer in group Ⅳ, Ⅴ and Ⅵ than that in control group. Conclusions Hypoxic air containing 15% O2 is appropriate for animal experiment of prenatal hypoxic adaptation. It is better to divide prenatal hypoxia into two episodes lasting 11.5 min and 13.33 min with a break of 5 min between them when animals breathe fresh air.

Objective To investigate the mechanism involved in the brain protection afforded by prenatal hypoxic adaptation by determining the quantitative variation in bcl-2 and bax mRNA expression.Methods Twenty-four Wistar pregnant (22d pregnant) rat were randomly divided into two groups: group I (hypoxia group) and group *** ( control group) . In group Ⅰ the pregnant rats were placed in an airtight cabin specially designed for hypoxic adaptation. When O2 % in the cabin decreased to 15%, the animals were taken out breathing fresh air for 5min and then placed back in the cabin and underwent another episode of hypoxia. In group Ⅱ the animals were placed in the cabin which was not tightly closed and underwent no hypoxia. 7 fetal or newborn rats were taken at 1st, 3rd, 24th, 48th, 72nd, 120th, and 168th h after prenatal hypoxic adaptation from each group and their brains removed for determination of bcl-2 mRNA and bax mRNA. Results In control group the expression of bcl-2 and bax were observed in the brain tissue of normal fetal or newborn rats from the 22nd day in the uterus to the 7th day postpartum during which there were no significant changes in bcl-2 gene expression while bax gene expression gradually decreased with time ( the decrease was of no statistical significance) . In hypoxia group bax gene expression decreased at 8th h after hypoxic adaptation and reached the bottom at 24th h which persisted until 120th h; while bcl-2 gene expression started increasing at 24th h after hypoxic adaptation and persisted until 72nd h. The bcl-2/bax ratio also started increasing at 8th h after hypoxic adaptation and peaked at 24th h and persisted until 72nd h. Conclusions In the brain tissue of fetal and newborn rats which have undergone prenatal hypoxic adaptation, bcl-2 gene expression is elevated, bax gene expression decreases and bcl-2/bax ratio increases. These changes are time -dependent.
