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.

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.

AIM: To observe the application of Suresight handheld auto- refractometer in measuring diopter of infants in Community Health Service Center.
METHODS:Totally 836 cases ( 1 672 eyes ) from June 2013 to December 2013 were examined diopter of infants by Suresight handheld auto-refractometer in Community Health Service Center.
RESULTS: Within 1 672 eyes of 836 infants were examined, 202 eyes were diagnosed ametropia, 38 eyes were suspicious, 240 eyes were transferred to the department of ophthalmology, the referral rate was 14.35%; 172 eyes were diagnosed ametropia, and the diagnosis rate of the referral patients was 71. 67%. Among 172 eyes, 46 eyes were provided with corrected glasses, accounting for 2. 75% of the number of screening, and 126 eyes were given intensive monitoring, accounting for 7.54% of the number of screening.
CONCLUSION: Application of Suresight handheld auto-refractometer in refraction screening for infants in Community Health Service Center is convenient and effective. With two - way referral between community health service center and department of ophthalmology can monitor and intervene vision development of infants much earlier.

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.

Brain metastasis ( BM) is a common brain tumor in a-dults, originating from extracranial location in the body. There has been a growing interest in producing suitable animal models for studying BM in vivo. Current BM models take peripheral or brain route for tumor cell inoculation, including intra-cardiac or intra-carotid artery injection or orthotopic injection. Direct im-plantation of patient tumor biopsies into rodent brain bears ad-vantages of clinical relevance. This review presents a compre-hensive introduction to key elements for establishing animal mod-els of BM, with highlights on selections of suitable model ani-mals, brain-seeking tumor cell lines, reasonable inoculation routes, as well as succedent phenotyping methods. In the end, perspectives and future directions in this field are discussed.

Objective To investigate the role of tyrosine kinase Src in a murine C.albicans infection model. Methods Observed cell proliferation by alarmarblue assay at 2, 24 and 48 h after Src inhibitor PP2 treatment. Phagocytosis was determined by a fluorometric assay. Cytokine TNF-αand IL-10 production was detected by ELISA. Results The 0~33.3 μmol/L PP2 had no effect on cell proliferation after PP2 treatment for 2 h. When the PP2 treatment extended to 24 or 48 h, PP2 (11.1, 33.3μmol/L) showed significant inhibition on cell proliferation with 78%, 9%, and 54%,13%, respectively. At 48 h after 11.1μmol/L PP2 treatment, the internalization of C.albicans in macrophage is significantly inhibited, contributing to the inhibition of cell proliferation. However, the 11.1 and 33.3μmol/L PP2 significantly inhibited the cytokine TNF-αand IL-10 production during C.albicans infection (P<0.01). Conclusion Src kinase played an important role during C.albicans infection, especially for the cytokine TNF-αand IL-10 production.

Objective: To investigate the roots and canals morphology o f extracted maxillary first premolars. Methods: The root morphol ogy and the root canals of 115 extracted maxillary first premolars were visualiz ed on radiographs taken in the mesio-distal direction, then the teeth were cut transversely and root sections were examined, the root canal systems was analyse d with Vertucci’s classification. Results: 74(64%) teeth were w ith one root, 41(36%) with two roots, all teeth with two roots had two canals a nd each canal with one apical foramen,〔TypeⅠ(1)〕.39% of the single-root teet h demonstrated one canal, whereas 61% of the single-root teeth had two canals, 〔TypeⅡ(2-1), TypeⅣ(2) and TypeⅤ(1-2)〕.Conclusions: The roots of maxillary first premolars possesses a variety of canal system types.

Objective:To investigate the root canal anatomy of one-rooted mandibular second molars. Methods:The root canals of 18 one-rooted mandibular second molars were visualized on radiographs and clinical examination, some specimens were cut at the mid-root level and observations were made on the coronal root section. Teeth with C-shaped canal system were categorized by using a modification of Melton classification.Results:12 molars exhibited C-shaped canals.2 molars were classified as category Ⅰ,5 as Ⅱ and another 5 cases as Ⅲ.Conclusions:C-shaped canals in mandibular second molars vary in canal number and shape.
