Objective To investigate the contamination of carbapenem-resistant Acinetobacter baumannii (CRAB) from object surface of key departments in a hospital,and identify whether these CRAB were homologous. Methods Environmental hygienic monitoring in intensive care unit (ICU),emergency intensive care unit(EICU), hemodialysis room and operating room was conducted.Acinetobacter baumannii (A.baumannii)isolated from ICU and EICU environmental specimens were amplified and typed by enterobacterial repetitive intergenic consensus-poly-merase chain reaction (ERIC-PCR).Results Except hand hygiene of health care workers in EICU was qualified, bacterial count of object surface of ICU and EICU were all unqualified;detection results of specimens from hemodi-alysis room and operating room were all qualified.A total of 53 specimens were taken from object surface of ICU and EICU,7 (13.21 %)A.baumannii isolates were isolated,and all were CRAB isolates,6 of which were of the same genotype and were identical with A.baumannii from patients’sputum.Conclusion CRAB isolated from object surface in key departments is homologous,cleaning and disinfection of environmental object surface should be inten-sified to reduce the occurrence of healthcare-associated infection.

SASP, 5-ASA, 4ASA are effectivedrugs for ulcerative colitis. They contain the same structure, but their action modes are different. The precise mechanism of salicylates are unclear. SASP,5-ASA inhibit inflammatory mediators, but 4ASA has no effect on PG or LT. 5-ASA has a strong force to scavenge the reactive oxygen metabolites. 4-ASA is weak in this aspect. The salicylates influence the function of several cy-tokines at different degree, such as IL-1, IL-6, IL-2, INF-a, TNF-r, GM-CSF, etc, probably bypreventing the binding of cytokine and receptor, or decreasing some cytokine synthesis and liberation. SASP inhibits neutrophilial cell degrandulation, releases lysosome and other enzymes, and changes the activity of lymphacyte. The salicylates also effect nitric oxide synthesis,adhesion molecules and the intestine permeability.

Liver cancer remains difficult to treat, owing to a paucity of drugs that target critical dependencies; broad-spectrum kinase inhibitors such as sorafenib provide only a modest benefit to patients with hepatocellular carcinoma. The induction of senescence may represent a strategy for the treatment of cancer, especially when combined with a second drug that selectively eliminates senescent cancer cells (senolysis). Here, using a kinome-focused genetic screen, we show that pharmacological inhibition of the DNA-replication kinase CDC7 induces senescence selectively in liver cancer cells with mutations in TP53. A follow-up chemical screen identified the antidepressant sertraline as an agent that kills hepatocellular carcinoma cells that have been rendered senescent by inhibition of CDC7. Sertraline suppressed mTOR signalling, and selective drugs that target this pathway were highly effective in causing the apoptotic cell death of hepatocellular carcinoma cells treated with a CDC7 inhibitor. The feedback reactivation of mTOR signalling after its inhibition is blocked in cells that have been treated with a CDC7 inhibitor, which leads to the sustained inhibition of mTOR and cell death. Using multiple in vivo mouse models of liver cancer, we show that treatment with combined inhibition of CDC7 and mTOR results in a marked reduction of tumour growth. Our data indicate that exploiting an induced vulnerability could be an effective treatment for liver cancer.

Objective To investigate the plasma expression of plasma prekallikrein(KLKB1)in latent autoimmune diabetes in a‐dults(LADA),type1diabetes(T1DM),type2diabetes(T2DM)andhealthypeople,anditsrelationshipwithLADAincombination with other indicators .Methods Among the four groups ,KLKB1 ,glycosylated hemoglobin(HbA1c) ,fasting blood glucose(FPG) ,2 h postprandial plasma glucose(2 h PG) ,Fasting c‐peptide(FCP) ,2 h postprandial C peptide(2 h CP) ,and glutamic acid decarboxy‐lase antibody(GADA)were detected respectively .And the detection results were analyzed by statistics .Results By comparison , there were statistically significant difference between LADA group and other groups on FPG(except for T2DM group) ,2 h PG , HbA1c ,FCP and 2 h CP(P< 0 .05) .And except for T1DM group ,there was statistically significant difference between LADA group and other groups on GADA ,too(P<0 .05) .The plasma expression of KLKB1 in LADA was significantly higher than those in T2DM group and NC group(P<0 .05) .The levels of KLKB1 was related with FCP、HbA1c、FPG、2 h PG(P<0 .05) ,and it was not related with age ,course ,and 2 h CP(P>0 .05) .Receiver operating characteristic (ROC) showed that only using KLKB1 to di‐agnose LADA had its limitation .Conclusion KLKB1 could be used as a clinical indicator to predict the onset of LADA to a certain degree .We could screen for LADA by using KLKB1 and other indicators in people at high risk .

PAX6 gene plays an important role in embryological development, and the mutation of this gene may result incongenital aniridia, retinoblastoma, macula hypoplasia, Peters' anomaly and so on. A brief introduction of the background PAX6 gene, and the association between PAX6 and retinal diseases were summarized in this review.

AIM:To evaluate the efficacy of treating traumatic optic neuropathy( TON) with mouse nerve growth factor.
METHODS: We searched the Cochrane Library, Pubmed, Medline, CNKI, Wanfang database and VIP to collect randomized controlled trials ( RCTs ) of using mouse nerve growth factor for TON. The quality of the included trials was assessed and poor-qualified trials were eliminated before the meta - analysis was conducted.
RESULTS:Seven RCTs with a total of 399 eyes included were retrieved, and OR=3. 78 with a 95%CI of [ 2. 35, 6.06], the difference was significant (P<0. 01).
CONCLUSION:The existing evidence supports that the prognosis of TON is better when mouse nerve growth factor are adopted in treatment, but there is still a need for well-planned, large-scale and multicenter RCTs to verify it.
