Objective To investigate the hemostatic effect of the radial hemostatic compression device(TR Band hemostatic gasbag)after transradial coronary intervention and discuss the optimal hemostasis time.Methods 266 patients who received transradial coronary angiography and used TR Band hemostatic gasbag for hemostasis were divided into group A,B and C,according to the compression time,the compression time in group A (90 cases)was 8 h,10 h in group B (87cases),12 h in group C (89 cases).The condition of bleeding,changes in blood oxygen saturation,and hand swelling in each group were compared.Results The bleeding rates of group A,B and C were respectively 16.7％,3.4％ and 9.0％,the difference was statistically significant.The incidence of hand swelling after operation in group A,B and C were respectively 27.8％,12.6％ and 21.3％,the difference was statistically significant.No significant difference was seen in blood oxygen saturation between three groups.Conclusions Application of radial hemostatic compression device after transradial coronary intervention proved good hemostasis effect,compression time for 10 h has the best effect and less adverse effect.

Based on the research project of the French language teaching reform in Kunming Medical College——the Application and Analogy of Modern Foreign Languages Pedagogy,the successes and disadvantages of the visual-audio-oral course were studied.The teaching reform's purpose and focal points were primarily introduced.Then,the successful experiences of academic period arrangement,teaching materials selection,in-class instruction and students' academic achievements were elaborated.Finally,by making a comparison of students' French language proficiency between the present experimental classes and the former ordinary classes,a few disadvantages of the reform were interpreted.

The British and French language analogy method in bilingual teaching was applied to the clinical students who were learning medical French in Kunming Medical University. Based on the students' good English foundation , a series of problems were solved properly such as contradictions between the professional course and foreign language classes , unmatched textbooks and teaching con-tents, the teachers' quality by lexical analogy and textual analogy and the rational allocation of the British and French language analogy teaching content. The teaching contents and methods were also properly worked out and good results were got.

Objective To explore the characteristics of illness attribution of outpatients with multiple somatic symptoms in Peking Union Medical College Hospital. Methods It was a cross-sectional study conducted from March to October,2012. A total of 150 outpatients were recruited from the departments of Gastroenterology,Traditional Chinese Medicine and Psychological Medicine by convenience sampling. Somatic symptom scale of the Patient Health Questionnaire (PHQ-15) was used to screening each patient in the waiting list. With the cut-off value of 10,patients were divided into the somatic symptom positive (SOM+) group and somatic symptom negative (SOM-) group. Sociodemographic characteristics were compared between these two groups. All the subjects completed interviews including questions about illness attribution. All the answers of illness attribution were concluded into three major groups as physical factors,situational factors and psychological factors. Results The proportion of female was significantly higher in SOM+ group than in SOM-group (69.3% vs. 53.3%;χ=4.048,P=0.044). In SOM+ group,significantly more patients contributed their illness to psychological factors (64.0% vs. 45.0%;χ=5.273,P=0.022). There was no significantly difference between SOM+ group and SOM-group on the phenomenon of multiple illness attribution (41.0% vs. 32.0%;χ=1.407,P=0.236). However,in the Department of Gastroenterology,there were significantly more outpatients in SOM+ group with multiple illness attribution (60.0% vs. 32.0%;χ=3.945,P=0.047).Conclusions The outpatients in general hospital with multiple somatic symptoms are more likely to contribute their illness to psychological factors. The phenomenon of multiple illness attribution is common among patients. Clinicians should increase their awareness and knowledge of illness attribution,so as to provide better holistic health services.

AIM:To investigate the role of reactive oxygen species (ROS) in the regulation of intracellular Ca2+induced by angiotensin II ( Ang II) in the primarily cultured medullary neurons .METHODS:Primarily cultured me-dullary neurons were prepared from 14-day-old embryos of Sprague-Dawley rats in the study .The identification of medullary neurons was assessed by double-labeling immunofluorescence .To explore the role of ROS , mainly the superoxide ( O2 ·-) , the O2 ·-generation was measured using the fluorogenic probe dihydroethidium ( DHE) .To determine intracellular free cal-cium concentration ( [ Ca2+] i ) , the neurons were loaded with the Ca 2+-specific dye Fura-2/AM.The cell viability after adding Ang II was also examined using CCK-8 assay.RESULTS:Most of the cultured cells were medullary neurons , more than 80%of which were glutamate positive neurons .Ang II (5 μmol/L) increased the level of ROS within 10 min in the medullary neurons .Ang II at 5μmol/L induced a significant [ Ca2+] i increase in the medullary neurons , and the effect of Ang II occurred rapidly and reached a peak within 20 min after administration.The level of [Ca2+]i started to decline after washout .The Ca2+elevation induced by Ang II was significantly decreased by apocynin or TEMPOL .No significant differ-ence in the cell viability between control group and 5μmol/L Ang II treatment group was observed .CONCLUSION:ROS is involved in the regulation of [Ca2+]i induced by Ang II in the primarily cultured medullary neurons , suggesting a poten-tial intracellular signaling mechanism involved in the Ang II-mediated oxidant regulation of central neural control of blood pressure.

AIM:To investigate the role of heat shock protein 70(HSP70)in hepatitis B virus (HBV) replica-tion.METHODS:The effect of HBV replication on the expression of HSP 70 was analyzed by RT-qPCR.The overexpres-sion efficiency of HSP70 was confirmed by Western blot .The effect of HSP70 overexpression on HBV DNA replicative in-termediates was analyzed by RT-qPCR and Southern blot .The effects of HSP70 overexpression on the expression level of HBV 3.5 kb mRNA and HBV core protein were measured by RT-qPCR and Western blot, respectively.The Effect of HSP70 overexpression on HBV promoter activity was detected by dual luciferase reporter system .RESULTS: The mRNA levels of HSP70 were inhibited by HBV replication .Overexpression of HSP70 repressed the expression of HBV DNA repli-cative intermediates, 3.5 kb mRNA and core protein, as well as HBV core promoter activity .CONCLUSION:HBV rep-lication inhibits the expression of HSP70.Overexpression of HSP70 represses HBV replication.These data suggest that HSP70 repressed HBV replication by inhibiting HBV core promoter activity .

Objective:To evaluate the validity and reliability of the Problem Area in Diabetes Scale (PAID) for assessing diabetes-related distress in patients with type 2 diabetes. Methods:Totally 203 outpatients with type 2 diabetes from a tertiary hospital in Beijing were selected. They were assessed with PAID,Hamilton Depression Scale (HAMD-17),Patient Health Questionaire-9(PHQ-9),World Health Organization Five item Well-Being Index (WHO-5 ),Mini-International Neuropsychiatric Interview (MINI)and HbA1 C. Item analysis and exploratory factoranalysis were conducted to test constructive validity. Concurrent validity was evaluated by the correlation coeffi-cients with the other instruments mentioned above. Totally 3 1 subjects were retested 4 weeks later to obtain the test-retest reliability. Results:Exploratory factor analysis produced 4 factors,including emotional,therapeutic,diet and perceived society support problems specific to diabetics. The total variance contribution ratio was 64. 33%. Except i-tem 7 and 20,no item was across two factors. The correlation coefficients of each item with relevant subscale score ranged from 0. 67 to 0. 86. The PAID scores were positively correlated with the scores of HAMD-17,PHQ-9 and HbA1C (r=0. 48,0. 43,0. 21,P<0. 001 or 0. 01),and negatively correlated with WHO-5 scores (r=-0. 46,P<0. 001). The Cronbach's αcoefficients were 0. 94 for the total scale and 0. 81 -0. 88 for the 4 subscales. The test-retest reliability coefficient was 0. 65 for the total scale and 0. 53-0. 73 for the 4 subscales. Conclusion:The validi-ty and reliability of the Problem Area in Diabetes Scale are acceptable in Chinese mainland,and can be available to assess the stress related to diabetics.

OBJECTIVETo investigate the effect of minocycline on hyperpolarization-activated current (Ih) in the substantia gelatinosa (SG) neurons in rat spinal dorsal horn.

METHODSIn vitro spinal cord transverse slices were prepared from 3-5-week-old male Sprague-Dawley rats. Using whole-cell patch clamp technique, Ih currents were recorded before and after bath application of minocycline (1-300 µmol/L) to the SG neurons.

RESULTSIh currents were observed in nearly 50% of the recorded neurons, and were blocked by Ih blocker CsCl and ZD7288. Minocycline rapidly and reversibly reduced the amplitude of Ih and decreased the current density in a concentration-dependent manner with an IC50 of 34 µmol/L.

CONCLUSIONMinocycline suppresses the excitability of SG neurons through inhibiting the amplitude and current density of Ih and thereby contributes to pain modulation.

OBJECTIVE: To explore the role of sinomenine in treatment of allergic rhinitis mice model and its possible mechanism. METHOD: We used ovalbumin (OVA) to make allergic rhinitis model of BALB/c mice. Saline was used in the control group. When we challenged the mice with OVA intranasally, the mice in sinomenine treatment group were feed by the food containing sinomenine. Mice were then killed 24 h after the last OVA challenge. The noses of mice from each group were removed en bloc and fixed, then each section was stained with hematoxylin and eosin. ELISA assay was used to measure the concentration of anti-OVA IgE, IL-4 and IFN-gamma. The proteins expressive level of T-bet and GATA3 were examined. RESULT: Nasal mucosa of the mice in sinomenine treatment group were not hyperplasia and without obvious infiltration of eosinophils. The concentration of anti-OVA IgE, IL-4 and IFN-gamma in the serum and T-bet and GATA3 expression levels of sinomenine treatment group were lower than those of allergic rhinitis group. CONCLUSION The sinomenine can be used to treat allergic rhinitis mice, and the mechanism may rely on the improvements of the Th1/Th2 imbalance.
