Objective Insulin resistance is a possible cause of polycystic ovary syndrome(PCOS).It is presumed that ectonucleotide pyrophosphatase/phosphodiesterase 1(ENPP1) is associated with insulin resistance.The purpose of this study is to explore the expression of ENPP1 in granulosa cells of the ovary and its relationship with PCOS. Methods Twelve aliquots of follicular granulosa cells were isolated from 12 samples of the patients with PCOS and 22 aliquots from 22 samples of the patients without PCOS,respectively.ENPP1 expression was analyzed by reverse transcription polymerase chain reaction(RT-PCR) and in situ hybridization.The relative expression of ENPP1 mRNA was detected by real-time quantitative polymerase chain reaction(real-time PCR). Results ENPP1 was expressed in granulosa cells of the ovary.ENPP1 expression's 2~(-?Ct) in granulosa cells of PCOS was significantly higher than non-PCOS(1.67?0.89 vs.0.94?0.76,P=0.017).Conclusion ENPP1 expression plays a role in ovary function and may be closely associated with the development of PCOS.

Objective To build model of intestinal motility disorders (IMD) in mice after severe craniocerebral trauma by using modified free fall impact method so as to lay the foundation for further study on development mechanism of postinjury IMD.Methods Severe craniocerebral trauma in mice was induced by a cylindrical sleeve rod impactor.Pathological changes of cerebral and intestinal tissue in mice were observed at 1,6 hours and 1,3,7 days after severe craniocerebral trauma.Brain water content and intestinal propulsion percentage were detected in each time point as well.Results Acute inflammation and congestion of the intestine were observed in phase of cerebral hemorrhage and edema after severe craniocerebral trauma in mice.Brain water content was increased at 6 hours and reached the peak at 24 hours.Intestine propulsion percentage showed a fall at one hour and dropped to the lowest level at 6 hours.Conclusions IMD exists in mice with severe craniocerebral trauma.The device involving modified Feeney free fall impact method can successfully establish animal model of IMD in mice with severe craniocerebral trauma.

Objective To investigate the distribution of acquired carbapenemases in carbapenemresistant strains of Klebsiella pneumoniae, and explore its role in epidemiology of nosocomial infection. Methods From November 2008 to March 2009, twenty clinical isolates of carbapenem-resistant Klebsiella pneumoniae were collected from children hospitalized in Wuhan children's hospital. MICs of antibiotics were tested by DNA of Klebsiella pneumoniae. Modified Hodge test was used to screen strains producing carbapenemases,combined imipenem(IPM)-EDTA , meropenem(MEM)- EDTA and ceftazidime(CAZ) - EDTA double-disk synergy test (DDST) were used to detect metallo-β-lactamase-producing. PCR amplification of the carbapenemase and integrase genes, and sequencing were performed. Plasmid conjugation transfer experiments and Southern hybridization were applied to study the mode of drug resistance transmission. Results Four types of Klebsiella pneumoniae were detected by PFGE, type A consisted of 5 strains, including 3 strains of type Al and 2 strains of type A2), type B (2 strains), type C (12strains) and type D (1 strain). Type A and C were the main drug resistant clones. Eight strains of Klebsiella pneumoniae carried both KPC-2 and IMP-4 genes, 10 strains carried IMP-4 gene, 2 strains carried KPC-2 gene. None of NDM-1 ,GIM, SPM, SIM, OXA-23, and VIM carbapenemase genes was detected in 20 isolates. All of 20 isolates carried lntl which were found to be located on bacterial chromosome by Southern blot. Conclusions KPC-2and IMP-4 genes are the major carbapenemase genes in Klebsiella pneumoniae isolated in Wuhan.Transmission of drug resistance is mainly through vertical transmission of type C resistant clone and horizontal transmission of Intl on bacteria chromosome.

Objective To investigate the molecular epidemiology of CRAB isolated from children in wuhan. Methods Forty non-repetitive strains of CRAB were collected from hospitalized children of emergency department, neonatal medicine, cardiothoracic surgery, bone surgery, respiratory medicine and renal medicine in Wuhan children's hospital during December 2008 and May 2009. MIC values were PFGE; KPC, IMP, GIM, SPM, SIM, OXA-23, VIM genes and integrase gene were amplified by PCR and then sequenced to confirm the genotypes.; Plasmid conjugation experiment was used to study the transfer method of bacterial resistance and southern blot hybridization was used to target the resistance genes. Results Susceptible rates of 40 strains to gentamicin, tobramycin, amikacin, ciprofloxacin, levofloxacin, trimoxazole were 20%, 5%, 93%, 93%, 95%, and 23% respectively. Eleven types of clone were detected by PFGE,including 29 strains of type A clone, 2 strains of type B clone, and 1 strain for each type of C to K clone. Eleven isolates produced both IMP-4 and OXA-23 carbapemase. Twenty-six isolates only possessed OXA-23 carbapemase. Thirty-six strains carried class Ⅰ integron. The results of southern blot hybridization showed that Intl, IMP-4 and OXA-23 type were located on chromosome. Conclusions Type A clone of CRAB is the most common. OXA-23 and IMP-4 type are the major acquired carbapemases, especially the OXA-23 is the most common type. The horizontal transmission of OXA-23 and IMP-4 gene mediated by Int1 and the spread of type A resistant clone is the major way of the spread of carbapenem-resistant Acinetobacter baumannii in the region.

The serum myocardial enzymes and isoenzymes activities were measured in 65 bum patients. The results showed that serum CK, CK-MB, LDH and AST activities, and CK-MB/CK and LDH1/LDH2 ratios were markedly elevated after burn injury. The CK-MB/CK ratio in major bum patients was higher than 0.05 1 -3d and 14d postbum. The results suggest that myocardial cells of serious bum patients are significantly injured in both early period and 14 d postbum.

OBJECTIVE: Off-label uses of drugs incur much debate, which is often encountered when doing prescription comment. The reasonability assessment of off-label uses is the key problem and requires solution urgently. This paper attempts to set up a normative evaluation process of off-label uses in routine prescription comment. METHODS: The off-label uses gathered in 2014 prescription comment were used for example. The off-label uses were searched in the Cochrane Library, and the results such as CDSR (Cochrane Database of Systematic Review), DARE (Database of Abstracts of Reviews of Effectiveness), RCT (Random Clinical Controlled Trial) and CCT (Clinical Controlled Trial) were screened according the criterion and analyzed. RESULTS: Eight Off-label uses were found with prescription comment. The edaravone for head injury, L-ornithine-L-aspartate for rise of hepatic transaminase, progesterone for urinary calculi and levocarnitine for myocardium protection were no evidence found in Cochrane Library, and were treated as irrationality. According to results of CDSR and DARE the edaravone for brain hemorrhage, and levocarnitine for cancer fatigue were not supported, but thymalfasin for cancer were supported. After assessing risk of bias with Cochrane tool, only under special circumstances can alprostadil for pulmonary hypertension (PH) or pulmonary arterial hypertension (PAH) be evaluated as conformation with evidence-based medicine. CONCLUSION: Assessment of reasonability for Off-label uses according to evaluation process using Cochrane Library can improve medication reasonability and safety, and increase the knowledge and competence of drug administration.
