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.

Objective:To observe the effect of low intensity pulsed ultrasound on early experimental osteoarthritis of rabbit knees.Methods:Experimental osteoarthritis of rabbit knees were made by Hulth's method.A total of 30 rabbits were divided averagely into 3 groups randomly.One hind knee of 10 rabbits of each group were treated with LIPU randomly while the others as control for 2、4 and 8 weeks respectively.All animals were sacrificed after LIPU.Then the histo-histochemical changes were evaluated by Mankin's score method.Results:Mankin's scores showed that the pathological changes in LIPU group were slighter than those in control group.Conclusion:LIPU can slow down the disease progress of experimental osteoarthritis of rabbit knee.

Objective]Observe the clinical effects of acupuncture treatment of athletes uterine bleeding. [Method]This study included 90 patients with uterine bleeding, randomly divided into three groups, treatment group 30 cases treated by acupuncture. The western medicine control group 30 cases treated with western medicine. Chinese medicine control group 30 cases were treated by traditional Chinese medicinal broth. One treatment course(after 30d) observation curative effect.[Results]The western medicine control group 15 cases cured, 6 cases were markedly effective, 6 cases better, 3 had no effect, the total effective rate was 90%. Traditional Chinese medicine control group 21 cases cured, 6 cases had marked effect, improvement in 3 cases, the total effective rate was 100%. Treatment group: 24 cases were cured, 3 cases had marked effect, improvement in 3 cases, the total effective rate was 100%.[Conclusions]Three treatments had curative effect, but the side effects of western medicine stopped taking the drug repeatedly; for the special athletes, the acupuncture treatment is worthy of popularization and application.

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 evaluate the role and surgical curative effect of the holmium laser under minor-caliber ureteroscope (F4.5) for the treatment of incarcerated ureteral calculus. Methods The holmium laser under minor-caliber ureteroscope (F4.5) was used to treat the incarcerated ureteral calculus with the course more than 2 months in 286 cases (334 sides) . Results 262 patients (304 sides) were successful in operation of single cavity treatment, with success rate of 91.6%. Conclusion Long course incarcerated ureteral calculus often associated with ureteral obstruction lesions (narrow,polyp,granulation hyperplasia,ureter cyst,etc.). Compared with thick ureteroscopy, minor-caliber ureteroscope has high single success rate for the treatment of incarcerated ureteral calculus with high safety, less complications, high gravel and platoon stone rates, and simultaneous treatment of the ureteral obstruction lesions.

Objective To explore the risk factors,composition of pathogen and drug sensitivity of pulmonary infection in neurosurgical intensive care unit(NICU) and provide basis forclinical effective prevention and appropriate treatment.Methods Retrospective analysis the detected pathogenic strains,theirdrug resistance and predisposing factors of the cases of pulmonary infection in NICU from January 2010 to September 2011.Results Among the isolated 602 bacteriastrains,363 strains (60.2％ ) were G-bacteria,71 strains ( 11.8％ ) were G + bacteria,168 strains (28 ％ )were molds.In G-bacteria,the main strains are acinetobacter and pseudomonas aeruginosa,and in G+ bacteria,staphylococcus epidermidis based most.Conclusion Acinetobacter has become the dominant flora of pulmonary infection in NICU and it has multidrug resistance to antibiotics in clinical.The Specific pathogen should be indentified through bacteriological examination of sputum as soon as possible,and the antibiotics should be used alternatively based on their drug sensitivity to control lung infection in critically ill patients.

Objective To investigate the prevalence of BK virus(BKV) infection in renal transplant recipients and the methods for its clinical diagnosis and treatment.Methods The urine and blood samples of 64 renal transplant recipients were taken for the BKV cytological and PCR tests.Five clinical factors were investigated to find the etiologic risks of BKV infection in renal transplant recipients.Four BKV infected recipients received experimental treatment.Results The occurrence of urine decoy cell,BKV viruria and viremia in all patients was(28.7 %),(17.2 %) and(6.3 %),respectively.The occurrence of urine decoy cell in serum creatinine(SCR) level elevated recipients was higher than that in SCR stable recipients(P=(0.04)).No significant relationships were found between the five clinical factors(gender,age,induction therapy,acute rejection episode,renal function after transplantation) and the occurrence of urine decoy cell,viruria and viremia.Ganciclovir treatment showed effective in four BKV infected recipients.Conclusions BKV monitoring is necessary for those recipients with evaluated SCR levels after renal transplantation.BKV viremia test can be used as a screening test.The efficacy of ganciclovir in the treatment of BKV infection should be further investigated.

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.
