OBJECTIVE:To establish early warning mechanisms of antibiotics drug resistance,and to provide reference for ra-tional drug use in the clinic. METHODS:The consumption amount of top 3 to 10 drugs in the list of consumption sum and amount in outpatient prescription and inpatient medical orders of our hospital during 2014 was analyzed statistically,including antibiotics, anti-tumor drugs,drugs for cardiovascular system,drugs for digestive system,biologicals. Top 5 Gram-positive bacterial and Gram-negative bacterial which induced infection in our hospital in Nov. 2014 was analyzed statistically in terms of resistant rate. RE-SULTS:Total consumption sum of drugs was 16 038.28 ten thousand yuan in our hospital in 2014,accounting for 27.95%;antibi-otics drugs accounted for 9.55%(1 531.44 ten thousand yuan) of total consumption sum,drugs for cardiovascular system 3.30%(529.60 ten thousand yuan),drugs for digestive system 8.32%(1 333.68 ten thousand yuan),anti-tumor drugs 2.93%(469.27 ten thousand yuan),and biologicals 3.50%(561.22 ten thousand yuan). 1 575 bacterial samples were detected in Nov. 2014,and bacte-rial were detected in 358 samples with positive rate of 22.73%. 136 Gram-positive bacterial were detected,and top 5 were Staphylo-coccus epidermidis, Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium and Streptococcus agalactiae. 222 Gram-negative bacterial were detected,and top 5 were Escherichia coli,Klebsiella pneumoniae,Acinetobacter baumannii,Hae-mophilus influenzae and Enterobacter cloacae. CONCLUSIONS:Five categories of drugs used in our hospital is rational compara-tively,and the proprotion of antibiotics in total consumption sum is much lower than other hospitals;control and standardization of antibiotics use has made some achievements.

Tyrosine kinase receptors mediate many critical cellular functions that contribute to tumor progression and metastasis.Recepteur d'origine nantais(RON)belongs to a subfamily of receptor tyrosine kinases(RTK)with unique expression patterns and biological activities.RON is activated by a serum-derived growth factor macrophage stimulating protein(MSP),primarily expressed in cells of epithelial origin.RON activation induced cell transformation,growth,migration and matrix invasion.We review RON molecular structure,activation,and carcinogenic mechanism related.It will contribute to cancel treatment and to discuss RON expression in the tumor.

Objective To investigate the influence of laparoscopic resection of colorectal cancer on (postoperative) micrometastasis of tumor cells.Methods Using cytokeratin,CK-20 mRNA as target gene,the RT-PCR method was used to examine the pre-and post-operative changes in the number of tumor cells in the peripheral blood of 48 cases of colorectal cancer.Results After operation,the number of tumor cells in(peripheral) blood was significantly higher in the laparoscopic surgery group as compared to that of traditional(laparotomy) operation group(P0.05),but was significantly related to positive rate of proliferating cell nuclear antigen(PCNA)(P

Objective To understand the the current situation of the slogans in the schistosomiasis health education from the linguistic aspect.Methods Sixty-two slogans in the schistosomiasis health education were collected,then the rationality and validity of them were analyzed from two aspects :the language form and the semantic content.Results Most of the slogans had the appropriate language form and the rational semantic content,they could propagandize the policy and educate the people very well,but there were still some slogans had the inappropriate language form or have the irrational semantic content and so on.Conclusion In order to make the slogans in the schistosomiasis health education more effective,we should attach importance to the language form and the semantic content of them.

Objective:To observe the clinical effect of Desensitizer Oravive combined Er:YAG laser irradiation on dentin hypersen-sitivity.Methods:240 molars in 86 patients with dentin hypersensitivity were divided into 2 groups(n =1 20).In control group De-sensitizer Oravive was applied to the teeth surface for 30 s;in combination group the teeth surfaces were treated by Er:YAG laser irra-diation for 60 s,and then by Desensitizer oravive for 30 s.Each tooth was treated only once.Pain and pain relief were evaluated by VAS before treatment and immediately,4,8 and 1 2 weeks after treatment.Data were statistically analyzed.Results:Before treat-ment,VAS showed no significant difference between the groups(P >0.05).Both groups exhibited lower VAS after treatment(P <0. 05),VAS values were lower(P <0.05)and the effective rate was higher in the combination group than those in the control group at each treatment stage(P <0.05).Conclusion:Desensitizer Oravive combined with Er:YAG laser is more effective than Desensitizer Oravive in the treatment of dentin hypersensitivity.

Objective To develop a fast shimming method for permanent magnet MRI system. Methods Peak location method (PLM) was improved by calculating the eddy current effect, and the time deviation was replaced by their phase to increase the precision. Results Experiment showed that the new method took less than 45 s, which was 3 times faster than conventional method while providing the same homogeneity. The result of PLM satisfied the requirement of homogeneity. Conclusion This new method can significantly improve the homogeneity in a short time and satisfy further fast pulse sequence development on 0.5T permanent magnet MRI system, which can be generalized for any permanent magnet first order shimming.

It was the honor to participate in the exchange program between University of Malta and Soochow University focusing on Dementia care;gerontology and elderly rehabilitation care from September 2016 to January 2017. During those 5 months, as a nursing graduate student, the experience which made me a deeply impression is the point of view ofperson-centred carefrom the medical care I′ve seen in Malta. This essay combined with the exchange experience through clinical observation and practice at hospitals in Malta, is going to highlight the point of view of person-centred care. That can reflect on some shortages of domestic in the medical care environment in China, hoping for a morehumane, moreperson-centred, andperson in heartmedical care environment.

Aim To investigate the toxicity of isopsor-alen in HepG2 cells and its effects on bile acid, bile acid synthesis and transport. Methods Cell viability was evaluated by MTT assay and bile acid was deter-mined inside HepG2 cells, with exposure to various isopsoralen for 24h. The mRNA transcription of BSEP, MRP2, MRP3, NTCP, OATP2, OSTα, CYP7A1, CYP27 A1 , FXR and PXR were assessed by real-time PCR. Results The cell viability was decreased dose-dependently with isopsoralen in HepG2 cells, and IC50 was 118. 1μmol·L-1 exposure to isopsoralen for 24h. Bile acid inside cells significantly increased with 100 and 400 μmol · L-1 isopsoralen. Isopsoralen caused the down-regulation of MRP2 , MRP3 , CYP7 A1 mRNA at 25 μmol · L-1 . Beside these, the up-regulation of OATP2,OSTα,CYP27A1,FXR,PXR with 100 μmol· L-1 isopsoralen, but there was no significant change of BSEP and NTCP. Conclusion The results show that isopsoralen induces bile acid accumulation and cytotox-icity which may be associated with the down-regulation of MRP2, MRP3 in HepG2 cells.
