OBJECTIVEThis study aimed to explore the effect of the up-regulation of Notch1 on osteoclastogenesis induced to osteoclasts by receptor activator for nuclear factor-kappaB ligand (RANKL) and macrophage colony-stimulating factors (MCSF) in vitro.

METHODSThe bone marrow stem cells (BMSCs) of Rosa(-notch1) mice were cultured and induced to osteoclasts by RANKL and MCSF. The BMSCs were transfected with the Ad-Cre-green fluorescent protein (GFP) virus or Ad-GFP virus. Total RNA from cells was extracted, and the gene expression levels of Notch1, Notch2, Notch3, Notch4, Deltal, Delta3, Delta4, Jagged1, Hes1, and tartrate resistant acid phosphatase (TRAP) were detected at the defined stage by reverse transcription-polymerase chain reaction (RT-PCR). Osteoclast formation was analyzed by TRAP assay.

RESULTSThe number of TRAP-positive multinuclear cells of the experimental group significantly decreased compared with that of the control group. The mRNA expression levels of Notch1, Notch3, Jagged1, Delta3, and Hesl of the experimental group were significantly higher than those of the control group, whereas the TRAP mRNA expression of the experimental group was significantly lower than that of the control group (P<0.05).

CONCLUSIONUp-regulation of Notch1 inhibit osteoclastogenesis of BMSCs induced by RANKL and MCSF in vitro.

Objective To investigate the effects of high molecular bio-degradable film on preventing peritoneal adhesion.Methods One hundred and twenty rats were divided into control group,non-bio-degradable film group and polycaprolactone(PCL) group.Animal models of peritoneal adhesion made by operations on rats serve as control group.In the study,non-bio-degradable film and bio-degradable,namely PCL films sensitive to pseudomonas enzyme,were put into the opening of peritoneum.The effect of the films on peritoneal adhesion was examined on 1,3,7 and 30 d after operation.Results Peritoneal adhesion was found in all the rats of control group and very low in PCL group and non-bio-degradable film group.Conclusion PCL film can effectively prevent the formation of postoperative peritoneal adhesion.

Objective To analyze the incidence rate of congenital malformations in Xintai City from January 2010 to December 2013,and to investigate the risk factors for neonatal malformations. Methods A total of 21 463 ca-ses of perinatal infants pregnant for 28 weeks later to postpartum 7 d in Xintai city from January 2010 to December 2013 were retrospectively analyzed. The congenital malformations detection data were analyzed. The risk factors were analyzed by univariate and Logistic analysis methods. Results There were 281 cases with congenital malformations were identi-fied out,and the congenital malformation rate was 1. 31%(281 / 21 463 cases). The incidence rates of multi - finger (toe)[0. 24%(52 / 21 463 cases)],cleft lip[0. 23%(49 / 21 463 cases)],and congenital heart disease[0. 22%(47 /21 463 cases)]were the main congenital malformations. Total malformation rates in the year of 2010,2011,2012,and 2013 were similar(1. 26% ,1. 25% ,1. 33% ,1. 26% ,Z = - 1. 826,P = 0. 068). Univariate and Logistic regression analysis results showed that birth weight,parity,births number,gestational age,educational level,residence,income,ill-ness history,exposure to pesticides,hepatitis,influenza,severe vomiting of pregnancy,threatened abortion,threatened premature,contraceptives,smoking history,drinking history,and father's chronic disease were the risk factors for neo-natal congenital malformations( χ2 = 10. 212,4. 299,5. 860,5. 278,10. 422,9. 327,15. 680,127. 395,245. 735, 74. 141,718. 876,96. 414,77. 770,11. 300,9. 126,74. 927,68. 283,5. 450,P = 0. 001,0. 038,0. 015,0. 022, 0. 001,0. 002,0. 000,0. 000,0. 000,0. 000,0. 000,0. 000,0. 001,0. 001,0. 003,0. 000,0. 000,0. 020 ). Conclusions Neonatal congenital malformation is mainly determined by genetic and environmental factors. For childbearing age and pregnant women,targeted health education should be strengthened to reduce the incidence rate of congenital malformations.

OBJECTIVE:To investigate the procurability and prices of essential medicines in Hubei Xiaogan rural area.METHODS:According to the standard methodology for the investigation of drug prices recommended by the World Health Organization and European Health Action International organization,a survey on the procurability and prices of essential medicines was conducted in 4 hospitals and 3 drugstores in Hubei Xiaogan rural area.RESULTS:The procurability of essential medicines in both hospitals and drugstores was low.The prices of drugs were lower in drugstores than in hospitals.As compared with the international reference prices,the drug prices in drugstores were lower while those in hospitals were higher.The markup ratio in one hospital was far above 15.0%,while those in the other two hospitals were all within 15.0%.CONCLUSION:The procurability of essential medicines in Hubei Xiaogan rural area remains to be increased,and there is space for the reduction of drug prices.

Objective To investigate the level change of interleukin-4(IL-4) and IL-12, and their effect on airway inflammation in rat asthma. Methods Rat model of asthma was set up by ovalbumin sensitization. Total cell count and eosinophil count in branchoalveolar lavage fluid(BALF) were performed, and levels of IL-4 and IL-12 in BALF were measured by ELISA. Results After ovalbumin sensitization, airway occurred obvious inflammation. Eosinophil count began increasing at 1 hour after sensitization, obviously increased at 8 hours, reached a maximum at 24 hours, started declining at 96 hours, and decreased to near normal range at 7 to 14 days. The changes of total cell count had the same tendency as eosinophil count changes. The level of IL-4 in BALF elevated at 1h after sensitization, reached a maximun at 8 to 96 hours, and reduced to near normal level at 7 to 14 days. The changes of IL-12 in BALF had the same tendency as IL-4 level changes. Eosinophil count was positively related with IL-4 level(r=0.74,P0.05). There was a close correlation between IL-4/IL-12 ratio and eosinophil count (r=0.85,P

OBJECTIVE To investigate the drug-resistance of ESBLs-producing Escherichia coli for guiding the clinical drug-using.METHODS The Kirby-Bauer agar diffusion method was used to analyze the drug resistance of 68 E.coli isolates in these three years.The ESBLs-producing strains were detected by confirmed test.RESULTS Thirty one ESBLs-producing strains were detected and the isolated rate was 54.4%;the resistant rates of these isolates were up to 50% to penicillin and three generations cephalosporin.The resistant rate to quinolone was about 70%.All of the strains were susceptible to imipenem.CONCLUSIONS More attention should be paid on the detection of ESBLs-producing E.coli and prevent the prevalence of the drug-resistant strains.

Through analyzing and considering on concrete conditions of the clinical engineering, which finds that the function allocation of department is not accurate and summarizes that should based on the technical support work and gain the development opportunity in the initial stage. According to the service theory of "all patients as the center" combines with economic and social benefits to analyze the specific circumstances of provincial and municipal hospitals, the functions location and development idea of clinical engineering department in all levels of hospital are researched respectively so that all work can be carried out smoothly and complete the important mission which hospital endow with the subject.

Objective To investigate the correlation between blood pressure variability and variabilities of some feature variables extracted from photoplethysmography (PPG) signal.Methods Continuous blood pressure (BP) and PPG signal were collected simultaneously from 19 healthy subjects under rest and after exercise.Eight feature variables were extracted from the PPG signal.The relationship between the beat-to-beat variability of BP and feature variables extracted from PPG were quantified by calculating Person's correlation coefficient.Results The variability of the amplitude of PPG was highly correlated with systolic BP variability both under rest (0.75) and after exercise (0.76).Meanwhile,the correlations between systolic BP variability and the variability of the time from the trough to the dicrotic north were 0.74(under rest) and 0.78(after exercise).Conclusion The amplitude variability of PPG is highly correlated with systolic BP variability and can be potentially used for monitoring BP variability.
