Objective To investigate the status of disinfection and sterilization quality of different levels of medical institu-tes in Xi’an,and improve the management level of disinfection and sterilization of medical institutes. Methods Disinfection and sterilization efficacy of 69 medical institutes were monitored and evaluated according to Standardization for Disinfec-tionTechniques (2002 edition)and Sanitary Standards for Hospital Disinfection (GB15982-1995). Results From 2011 to 2013,2 224 specimens were tested,1 766 (79.41% )were qualified.The qualified rate of tertiary medical institutes was higher than second and below medical institutes (83.67% vs 77.50% ,P= 0.001),the qualified rate between public medical institutes and private medical institutes was not statistically different (79 .64% vs 78 .20% , P= 0.532),the qualified rate of comprehensive medical institutes was higher than specialized medical institutes (80.18% vs 74.92% ,P= 0.030). Of different detected specimens,the qualified rates of disinfectant in use and pressure steam sterilizers (including test pack and process challenge device)were higher (98.46% ,100.00% ,and 98.06% respectively),while the hands of health care workers (HCWs)and glutaraldehyde were lower(58.48% and 43 .28% respectively).Conclusion Disinfection and sterilization quality in different medical institutes in Xi’an is dif-ferent,and different disinfected and sterilized objects are also varied .It is necessary to intensify the management of hand hygiene of HCWs and concentration of glutaraldehyde.

AIM: To investigate the possible impact of conductive keratoplasty(CK)on intraocular pressure( IOP ).METHODS: 36 eyes of 20 patients with hyperopia underwent IOP measurement with non-contact tonometer (NCT), Goldmann applanation tonometer (GAT) and Schiotz tonometer before and after CK.RESULTS: After CK, a significant decrease was observed by NCT, GAT and Schiotz measurements. The change in IOP readings was not correlated with age, sex,keratometric readings, or attempted correction.CONCLUSION: The applanation tonometer atend to underestimate the true IOP after CK.

OBJECTIVE: To investigate the instruction for drug use for pregnant and lactating women and to provide reference for standardizing drug package inserts. METHODS: Four hundred and ninty drug instructions sampled from the pharmacy in our hospital were investigated and analyzed on the part for pregnant and lactating women medication by Provisions for Drug Insert Sheets and Labels, Regulatory Guidelines for the chemicals non-prescription drug, Regulatory Guidelines for chemicals and living creature product and other references. RESULTS: In prescription medicines, The rate of pregnant and lactating women to use the medicine circumstance marked was 53.91%, and that of "not yet clear" or "still have no data" was 13.28%, and the other 32.81% have never carried on to mark. In non-prescription medicines, The rate of pregnant and lactating women to use the medicine circumstance marked was 46.23%, 53.77% have never carried on to mark. CONCLUSION: The contents of pregnant and lactating women medication are far from perfect, Which should draw attention to better management.

Objective To explore the effect of physical condition on autonomous social participation function in stroke patients. Meth-ods A survey was conducted on 283 cases of stroke patients from October, 2014 to September, 2015. They were tested with General Situa-tion Questionnaire, Disease Status Questionnaire, Impact on Participation and Autonomy Questionnaire (IPA), Chinese Stroke Scale (CSS), and Mini-Mental State Examination (MMSE). Results Multivariate regression analysis showed that age, scores of MMSE and CSS, and physical disabilities were the factors related with autonomous social participation function in stroke patients (t>2.513, P<0.05). Conclusion It is needed to prevent and treat the complications of stroke early, which may contribute to the improvement of autonomous social participa-tion in stroke patients.

ObjectiveTo retrospectively analyze the relationship between clinicopathological,biological characteristics and the outcome of renal cell carcinoma(RCC) and evaluate the risk factors related to metastasis in young patients.MethodsThe data of 83 RCC patients younger than 40-year-old, treated from January 1986 to December 2007 in Tianjin Cancer Hospital,were analyzed retrospectively.The complete follow-up data of the 83 cases were collected.The operative methods included partial and radical surgery.Clinical staging were consistent with the 2004 UICC TNM classification criterion.The histological sections were reviewed.Various biological factors including VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-kit and PCNA were tested by immunohistochemistry staining.The adjuvant radiation therapy, chemotherapy and immunotherapy after operation were carried out on the basis of pathological and biological features.The 83 cases were divided into two groups according to metastasis and non-metastasis status within 5 years.The prognosis related factors including clinical factors, pathological and biological factors were evaluated.Chi-square test was used for the analysis of 5-years metastasis status; and multivariate analysis was carried out using Cox proportional hazards models to assess the independent effect of the metastasis factors (the test standard α = 0.05).ResultsThe 5-year follow-up data showed that the metastasis rate in the 83 cases was 16.87％ (14/83).The Chi-square test results indicated that the patients with clinical stage Ⅲ and grade 3 had the highest metastasis rate (57.14％ and 78.57％respectively,x2 =38.042, x2 = 9.820; Ps ＜ 0.01) .The VEGFR-3 and PCNA positive expression rates were 92.86％ and 85.71％ respectively in metastasis group.The metastatic risk of early stage patients was 3.444 times as much as the advanced stage patients.ConclusionThe young patients with clinical advanced renal cell carcinoma had worse outcome.The stage,grade, VEGFR-3 and PCNA expression were the risk factors correlated with the metastasis risk for young RCC patients.TNM stage was an independent predictive risk factor of metastasis in young patients.

In recent years,research on autoimmune pancreatitis (AIP) has gained significant progress.AIP is a special type of chronic pancreatitis which is mediated by an autoimmune mechanism.It is characterized by the infiltration of lymphocytes and plasma cells leading to pancreatic fibrosis and dysfunction.AIP can affect the bile ducts,salivary glands,kidneys and other organs outside the pancreas.The common manifestations include obstructive jaundice,abdominal pain,and weight loss,which are similar to pancreatic cancer.Steroid therapy is of significant effect.There is no consensus nowadays on the diagnostic criteria of AIP across the world.There are many studies on the pathological subtypes,imaging,serological markers and biopsy techniques on AIP,and research focuses on the differential diagnosis from pancreatic cancer.
