The genes for TEM and aminoglycoside-modifying enzymes (AMEs) in Acinetobacter baumannii were studied to provide molecular biological support for monitoring their drug resistance.MethodsTwenty strains of Acinetobacter baumannii were clinically isolated from the period of August, 2002 to Feburary, 2004. The drug resistance of these strains to thirteen kinds of antimicrobial agents was tested by microdilute test. The TEM and AMEs genotypes of these strains were analyzed by polymerase chain reaction and verificated by DNA sequencing .Results All twenty strains were sensitive to Imipenam and Meropenem. The resistant rates of the twenty strains to Piperacillin/ Tazobactam, cefepime and ceftazidime were 45.0%, 65.0% and 70.0%, respectively. The resistant rate to aminoglycosides antibiotics was 75.0%. The resistant rates to other antimicrobial agents were greater than 65.0%. The positive rate of genotype TEM, aac(3)-Ⅰ, aac(3)-Ⅱ aac(6”)-1 and ant(3”)-Ⅰ were 45.0%, 55.0%, 15.0%, 35.0%, and 60.0%, respectively. The genotypes of SHV, AmpC DHA and AmpC MIR were all tested negative.Conlusions The multiple-drug-resistance of Acinetobacter baumannii isolated from Tongde Hospital was a serious issue.There were high percentages of TEM and AMEs genotypes. Because of the imperfection frame of the primer,some familiar genes just like OXA,VER and PER were not experimented. We shall further discuss the drug resistance of the third/fourth generations cephalosporin.

Effects of thioproline on thrombus formation and platelet function were studied. Thioprolline given in vitro ( 1 g/L ) or ex vivo ( iv 25mg /kg ) shortened length of thrombi and decresed the wet and dry weight of thrombi in rabbits or rats. Thioproline given iv vitro ( 1 g/L ) or ex vivo ( iv 50mg/kg ) inhibited platelet adhesion and aggregation induced by ADP in rabbits.

Objective: To analyze the status quo of assanation and ethics courses and their social requirement, thus to explore a scientific mode for the course setting; Method: The course setting status quo of assanation and ethics is analyzed among 18 colleges in which the nursing speciality is set up. A questionnaire was also conducted to investigate students' inclination towards politics-sorted courses, and relevant data were analyzed. Results: The establishing rate of assanation courses in the higher professional colleges is higher than that in the comprehensive universities. The most favorable subjects among freshmen are the Chinese national political theories, and assanation & ethics, while the counterparts among seniors are assanation & ethics, law basis, and philosophy. Seniors have an obvious higher desire for the course of assanation & ethics compared with freshmen (P

Objective To study the pathologic feature and rational diagnosis and treatment of Mirizzi Syndrome. Method The clinical data of 43 cases treated by surgery were retrospectively analysed. Results All the 43 cases underwent operation, including partial cholecystecomy in 8 cases, cholecystectomy in 16cases , cholecystectomy plus common bile duct exploration with T tube drainage in 9 cases, choledochojejunostomy in 10 cases. Of the 43 cases, 36 cases were followed up for 1～5 years. Of them, 29 cases were in excellent, 6 cases in good and 1 case in poor. Conclusions The pathologic type of Mirizzi Syndrome is variant. It is difficult to make a definite diagnoses before operation. So vary imaginal technique should be adopted. Different operative procedures should be used according to patients' pathologic type.

Objective To investigate the polymorphism of human cytomegalovius UL143 gene of low passage clinical isolates in Guangzhou,China.Method PCR was performed to amplify the entire HCMV ULl43 gene region of 3 clinical isolates,which had been proven by multiplex PCR.The amplification products were cloned into pMD18-T-Vector and subjected to sequencing.The result of DNA sequences were analyzed together with the one of published homologous sequences in GenBank from 14 clinical isolates.Result There were several stop codons in UL143 gene due to a base deletion in open reading frame (ORF) of D3 isolate,which could lead to produce non-functional protein.UL143 ORF of Toledo isolate consisted of 279 nueleotides,encoding a protein with 92 amino acids.UL143 ORFs of other isolates consisted of 252 nueleotides,encoding a protein with 83 amino acids.The DNA sequences were quite conserved and all the variations were base substitution.The amino acid sequences of different isolates were highly conserved.with variation of 1.2%-2.4%.There were no additional or deleted sites of post translational modification of UL143 protein in all clinical isolates except Toledo isolate.There were some differences in the secondary structure among different isolates.The isoelectric point of UL143 protein of all clinical isolates except Toledo isolate was 8.75.Conclusion All DNA and deduced amino acid sequences of UL143 gene shared great similarity among HCMV clinical strains regardless of their polymorphism.

Objective: To investigate the effect of the frenulum identification positioning method with a disposable suture device in circumcision for the prevention of postoperative penile frenulum malposition. METHODS: Totally 212 patients with phimosis or redundant prepuce underwent circumcision from March 2015 to September 2016, including 109 cases of conventional circumcision (the control group) and 103 cases treated by frenulum identification positioning with a disposable suture device (the observation group). We observed the postoperative position of the penile frenulum and median raphe and compared the deviation angles of the frenulum between the two groups of patients. RESULTS: The median of penile frenulum deviation angle (interquartile range) was 0 (3.56) in the observation group, significantly smaller than 12.41 (19.59) in the control (P <0.001, P = 0.000). And the rate of frenulum deviation was remarkably lower in the former (8.74% ［9/103］) than in the latter group (66.06% ［72/109］) (P <0.01). CONCLUSIONS Circumcision using the frenulum identification positioning method with a disposable suture device can effectively avoid postoperative penile frenulum malposition. With the advantages of safety and easy operation, it deserves clinical application and popularization.

Summary: To investigate the difference in expression of hTERT gene between HbsAg-positive human hepatocellular carcinoma (HCC) and HbsAg-negative HCC and to explore the relationship between HBV infection and hTERT gene expression in HCC. The expression of hTERT protein in 30 cases of HbsAg positive HCC and 17 cases of HbsAg negative HCC was detected by immunohistochemistry (SP method), and the expression of hTERT mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). t-test, Chi-squared test and cochran- armitage trend test were used to see whether there was an interrelation between HBsAg and hTERT gene in HCC. The expression of hTERT protein was mostly located in plasm and occasionally in the nucleus of liver cancer cells. The positive rate of hTERT protein and hTERT mRNA in HbsAg positive HCC- 93.33 % (28/30) and 83.33 % (25/30) respectively which were much higher than those in HbsAg negative HCC- 52.94 % (9/17), 47.06 % (8/17) (P<0.01) respectively. HbsAg is related to hTERT gene expression in human hepatocellular carcinoma. The hTERT gene activated by the efficacious ingredient of HBV may play an important role in hepatocellular transformation and carcinogenesis.
