Objective To evaluate the teaching effectiveness of applying article structure analysis to improve medical graduate students' ability to read research articles.Methods 48 medical graduate students from basic medicine school of the Fourth Military Medical University were randomly and equally divided into the experimental group and control group.In the reading ability training of scientific research papers,the experimental group used the teaching of the structure analysis,while the control group used the collective self study.Before and after the training,the two groups of students were implemented a unified reading ability test and self reading ability evaluation survey,and after the training,the teaching satisfaction survey was conducted among the experimental group only.SPSS 16 was used to analyze the correlation data and Wilcoxon for signed-rank t est.Results After training the reading ability test results showed that reading ability score (P=0.013),consumed reading time score (P=0.003) and reading efficiency (P=0.004) of the experimental group were significantly higher than those of control group.The two groups of students' self-evaluation of the reading ability showed that after training,the scores of the students in the experimental group were higher than those in the control group,and the differences were statistically significant (P values were less than 0.05).The experimental group students' teaching satisfaction survey to article structure analysis showed students' score in 6 survey contents were greater than 3,namely degree of evaluation was more than general,among which,the score of four survey contents was more than 4,that is to achieve satisfied or very satisfied.Conclttsion Applying article structure analysis can significantly improve medical graduate students' ability to read research articles.

Objective To investigate the acoustic characteristics of snoring sound in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and with simple snoring. Methods 22 patients with OSAHS and 15 with simple snoring were included in this study. Natural overnight snoring was digitally recorded and portable sleep mo-nitoring was performed simultaneously. 10 snores, which were the 1st snores after 10 cycles of obstructive apnea, from each patient in OSAHS group, and 10 snores from each patient in simple snoring group were analyzed in the time and frequency domains. Results The sound waves of snoring in the two groups exhibited different patterns both in the time and frequency domains. The snoring spectrum of patients with simple snoring showed distinct fun-damental- harmonic structures which were not clear in patients with OSAHS. The central frequency of the patients with OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with simple snoring. In the OSAHS group, the central frequency of the patients with moderate-to-severe OSAHS was higher, and 800 Hz power ratio was lower than those of the patients with mild OSAHS. The differences of the two parameters were of statistical significance. Conclusion The snoring sounds in patients with OSAHS and with simple snoring have dif-ferent characteristics in time and frequency domains, indicating that it is feasible to research the OSAHS by way of snore monitoring and analyzing technique.

Objective To investigate whether TG2 plays an important role in the osteoblast differentiation and mineralization.Methods TG2 mRNA of SaOS-2 cells was knocked down using a lentivirus stably expressing short-hairpin ( sh) RNA targeting TG2.Then the cells were cultured in osteo-inductive medium for 14 d to measure mineralization and for 7 d to measure the levels of osteoblastic differentiation markers including ALP activity and mRNA of collagen I, osteocalcin ( OCN) and BMP-2.The wild-type SaOS-2 cells and scrambled shRNA-transducted SaOS-2 cells served as the controls. Results The controls displayed an increasing trend of the level of ALP activity and mRNA of collagen I, osteocalcin and BMP-2,and notable mineralization at 14 d.When TG2 was knocked down, ALP activity, mRNA of collagen I, osteocalcin and BMP-2 at 7d,and mineralization at 14 d were all significantly lower in comparison with the corresponding values in the controls.Conclusion TG2 is involved in the differentiation and mineralization of osteoblasts in vitro.

Wistar rats(n=24) were divided into normal control group(NC), food restriction group(FR), and catch-up group(RN). Serum glucose,lipids, gastrin, the ratio of visceral fat to body fat, adipocyte CCK2R mRNA and protein levels were determined. Compared with NC group, FR rats had lower serum gastrin and visceral fat formation. The adipocyte CCK2R mRNA and protein levels of FR rats were lower than those of NC rats. Serum gastrin level of RN rats was higher than those of FR and NC rats(P＜0.05). The ratio of visceral fat to body fat in RN rats increased compared with FR rats and was close to that of NC rats. The adipocyte CCK2R mRNA and protein levels of RN rats were higher than those of FR and NC rats. Gastrin and its receptor pathway possibly play a role in the mechanism of visceral fat accumulation in catch-up rats.

Cultured primary human umbilical vein endothelial cells (HUVECs) were divided into 4 groups:normal control( NG ),persistent high glucose ( HG ),hyperglycemia group ( TG ),and mannitol control ( MA )groups.After 1,4,and 7 days of culture,cells were collected.Cell proliferation,cell apoptosis,ROS,SOD,MDA,and NO level,eNOS mRNA and protein level were measured.Endothelial cell proliferation was inhibited in HG,TG,and MA groups compared with NG group.Hyperglycemia memory induced apoptosis of endothelial cells,increased ROS and MDA generation,and down-regulated intracellular SOD level,findings similar to those in HG group.After 24 h of culturing,eNOS expression and NO generation in both HG and TG groups were higher than those in NG group.However,after 7 days of culturing,eNOS expression and NO generation in both HG and TG groups were lower than those in NG group.These results suggest that in hyperglycemia memory cell model,transient hyperglysemia may lead to persistent imbalance in oxidative stress and reduce endothelium-derived relaxing factor NO level,indicating that hyperglycemia memory may play an important role in persistent vascular endothelial cell injury.

ObjectiveTo explore the bone anabolic effects after a single local injection of simvastatin into femoral cavities of osteoporotic rats.MethodsThirty-six female SD rats(3 months old,body weight 250-300 g) were ovariectomized(OVX) and low-calcium-diet fed for 3 months,OVX rats were randomized into 3 groups(n=12).Left femurs of group A,B and C were injected with 0,5 and 10 mg simvastatin,respectively.Half of the rats in each group were randomly euthanized separately 1 and 5 months after simvastatin injection.Left femurs were taken out for bone mineral density (BMD) assessment with dual energy X-ray absorptiometry,bone histomorphometic changes were analysized by Micro-CT,and two kinds of biomechanical tests were used to evaluate the osteogenic effects.ResultsOne and five months after injection,BMD in mid-diaphysis significantly increased in simvastatin-injected groups compared to the control group.For Micro-CT analysis,significant increase in total bone volume/total tissue volume,cortical wall thickness,trabecular thickness,trabecular number,and a significant decrease in trabecular spacing were observed in simvastatin-injected groups compared to the control group.For both biomechanics (the three-pointbreaking test of condyles and axial compressive testing of proximal femur),the values were significantly higher in simvastatin-injected groups than the control group.ConclusionLocal simvastatin treatment showed a positive effect on improving mechanical strength,structure of osteopenic femurs and BMD.Our findings may provide a new strategy for the prevention and treatment of osteoporosis,especially for osteoporotic fractures.

ObjectiveTo evaluate the treatment efifcacy of the treatment promotion of standardized management for chil-dren with asthma.MethodsMedical records of 150 children with asthma were reviewed and divided into management group or control group according to whether standardized management was accepted. Comprehensive asthma education for asthma pa-tients and their parents including asthma associated basic knowledge education, health education as well as follow-ups at deifned intervals was conducted in 78 cases. In the meantime, standardized asthma therapies were performed. Control group involved 72 cases who did not receive asthma education managements and only accepted regular clinical therapies. After 1-year observational follow-up, , clinical efifcacy of children with asthma, changes of knowledge-attitude-practice of parents, and compliance of med-ication were compared between the two groups.ResultsAfter promotion of standardized managements treatment, asthma con-trol rates in the management group were signiifcantly higher than that of the control group(χ2=54.68,P<0.01); In addition, the rate of asthma attacks, emergency visits as well as hospitalizations were obviously reduced in the management group than control group (both withP<0.01). Knowledge associated with asthma, therapy and management executions as well as knowledge-atti-tude-practice of parents also demonstrated apparent elevations in the management group (P<0.01); At the same time, management group has illustrated superior medication compliance over the control group (χ2=66.27,P<0.01).ConclusionPromotion of standardized treatment management among children with asthma can help to achieve effective control by raising levels of knowl-edge-attitude-practice of the parents as well as the patient’s compliance to the treatment.

BACKGROUND: Cristata L flavonoid is a kind of plant estrin, which possesses multiple physiological function, has no toxicity and adverse effect, and is effective in treating and preventing osteoporosis.OBJECTIVE: To study the effect of cristata L flavonoid on bone morphogenetic protein, urine inorganic salt and content of lysozyme of rats with diabetes mellitus (DM).DESIGN: Randomized grouping design and controlled study.SETTING: Pharmaceutical Laboratory of Xinxiang Medical College.MATERIALS: The experiment was completed in the Xinxiang Medical College from September to December 2003. Totally 24 health male SD rats were randomly divided into three groups: normal control group, diabetes mellitus (DM) group, DM + cristata L flavonoid group with 8 in each group.were injected intraperineally with 60 mg/kg streptozotocin, and 48-72 hours later, blood of rear caudal vein was collected to measure total blood glucose.Rats were determined as DM if the blood glucose was ≥ 16.7 mmol/L; oth erwise, 60 mg/kg streptozotocin was injected once more. After modeling,cristata L flavonoid and rats in normal control group were given the same was measured with atomic absorbency method and content of urine sodium histochemistry of bone morphogenic protein-2 (BMP2) in bone was detected with streptavidin tagged by peroxidase and immunohistochemic expression lysozyme reflected reabsorption function of renal tubule was measured with with t-test. MAIN OUTCOME MEASURES: Comparison between content of calcium, sodium, kalium in urine and lysozyme and immunohistochemic expression of BMP2 10-week intervention later.calcium and sodium in urine in DM model group were obviously higher than those in normal control group, but content of kalium in urine was obviously lower (P ＜ 0.05-0.01). Contents of calcium in urine in DM +cristata L flavonoid group were obvioualy lower than those in DM model group and normal control group were obviously higher than those in DM model group, and content of lysozyme in urine in those groups was obviously lower than that in DM model group (P ＜ 0.05-0.01).CONCLUSION: Expression of BMP2 of DM rats is decreased, but after supplement of cristata L flavonoid compound, the expression is increased.In addition, output of urine calcium and sodium in DM rats is decreased,and reabsorption function of renal tubule is increased.
