OBJECTIVE To understand the current situation in management of nosocomial infections in hospitals,and provide rational preventive measures in order to improve the medical care quality.METHODS An observatory study was conducted and reasonable suggestions were preferred referring to foreign nosocomial infections modes.RESULTS Problems were found to a different extent in administration of nosocomial infections.Most alarming problems were shortages of rules and regulations,and deficiency of infection propaganda and administration coordination.CONCLUSIONS Strengthening management of nosocomial infections is one of the key issues for improvement of the medical care quality and should be paid special attention.

Objective: To search for new isoflavones with more potent antitumor activities from the target compounds synthesized by inserting a double bond or an acetylene bond between chromone and its 3-substituted phenyl, ester and hydroxymethyl groups, or by formation of an amide of 3′ or 4′-amino group of isoflavones with norcantharidin. Methods: The key intermediate 3-iodo-7-methoxyl-4H-chromen-4-one (5) was prepared with 2-hydroxyl-4-methoxyl- acetophenone and ethyl formate. The target compounds with 3-substituted double bond or acetylene groups were synthesized by Heck coupling and Sonogashira coupling reaction; the amide compounds were synthesized by Suzuki coupling reaction and amide formation of 3′ or 4′-amino group of isoflavones with norcantharidin. All of the target compounds were confirmed by 1HNMR, MS and IR spectra. The IC50 values of target compounds were determined by the standard method using two kinds of human tumor cell lines, colon cancer cell line HCT116 and liver cancer cell line SMMC 7721 to study their anti-tumor activities. Results: All the 17 target compounds obtained had certain anti-tumor effect in vitro, with compounds 7h and 7e showing better anti-tumor effects, which were similar to that of control curcumin and more potent than that of genistein in vitro. Conclusion: The insertion of a double bond or an acetylene bond between chromone and its 3-substituted phenyl, ester and hydroxymethyl groups may promote the anti-tumor activities of isoflavone analogues. It seems that the formation of an amide of 3′- or 4′-amino group of isoflavones with norcantharidin has no noticeable promotion effect on the anti-tumor activities.

AIM: To compare the efficacy and safety of bevacizumab with mitomycin ( MMC ) in augmenting trabeculectomy for glaucoma.
METHODS: Databases including PubMed, CBM, CNKI, VIP and WanFang Data were electronically searched for all randomized controlled trials ( RCTs) about comparing the efficacy and safety between bevacizumab and MMC in augmenting trabeculectomy for glaucoma before the date of Jun. 2016. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, and evaluated the included studies. Then, Meta-analysis was performed.
RESULTS: A total 4 RCT involving 286 eyes ( 143 for bevacizumab group, 143 for MMC group) were included. The results of Meta-analysis showed that there was no significant difference between bevacizumab and MMC in the last follow-up after surgery in IOP (WMD=2. 21, 95%CI: -0.17 to 4.58, P=0.07), complete success rate (OR=0. 69, 95%CI:0. 26 to 1. 81, P=0. 45) and the numbers of anti-glaucoma medicine ( OR= 0. 12, 95%CI: -0. 15 to 0.39,P=0. 39). And there was no significant difference between bevacizumab and MMC in postoperative complications:hypotony (OR=0.7, 95%CI:0.12 to 4.05, P=0.69), bleb leak (OR=1, 95%CI: 0. 21 to 4. 74,P=1), encapsulated bleb (OR=1. 15, 95%CI: 0. 38 to 3. 44, P=0.81), choroidal detachment (OR=1. 22, 95%CI: 0. 29 to 5.22, P=0. 78) and cataract (OR=1. 15, 95%CI: 0. 38 to 3.44, P=0. 81).
CONCLUSION: Bevacizumab and MMC in augmenting trabeculectomy for glaucoma have similar efficacy and safety. Bevacizumab can't result in better outcome in term of IOP reduction. Clinicians should choose suitable solution according to disease characteristics.

Objective To explore the incidence and distribution features of neonatal phenylketonuria(PKU) and congenital hypothyroidism(CH) in Lianyungang area.Methods The heel blood samples dried on filter paper was collected from newborns after 72 hours.As the screening indicators,PKU was detected through serum phenylalanine concentration(Phe) detection by Guthrie′s bacterial inhibition assay and CH was detected through serum thyroid stimulating hormone(TSH) levels detection by time-resolved fluorometry(TRFIA) or enzyme linked immunosorbent assay(ELISA).Results Sixty-four children with CH were diagnosed and the rate of CH was 1∶2423,41 patients were examined by thyroid gland nuclein kinescope picture,among which there were 23 patients whose thyroid glands were unusal.These patients lived in 45 towns(streets),which had no difference between men and women,city and country side.A couple of twins were screened for CH;15 cases of PKU was detected with an incidence of 1∶10 339.These patients′ parents were neither consanguineous marriage nor dominance hereditary family history.Their physical and mental development were similar to the same age children after interventive treatment.Conclusions The distribution of CH and PKU is diffuse in Lianyungang.Neonatal screening is the only valid means to find patients with CH and PKU.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.
