Objective To evaluate the effect of community health education on pre-hospital delay and clinical outcomes of hospitalization of the patients with acute myocardial infarction.Methods Community health education for the adults living near the Linyi People's Hospital was conducted from July 1st to October 30th,2012.ST-elevation acute myocardial infarction identified 1 year prior to or during the health education program was used as control (n=81) or study group (n=89),respectively.Delay from the onset of ST-elevation acute myocardial infarction symptoms to hospital admission,the rate of reperfusion therapy,the in-hospital malignant complications and the death rate were compared between the two groups.Student's t test,Chi-square test,Fisher's exact probability test and the Wilcoxon rank sum test were used for data analysis.Results Median pre-hospital delay was 80 (47-150) min in the study group,less than 90 (60-255) min of the control group (Wilcoxon W=6 912.00,Z=-2.182,P=0.029).The rate of reperfusion therapy was 54％ in the study group,higher than 38％ of the control group (x2 =4.181,P=0.041).The overall incidence of severe complications during hospitalization was 24％ in the study group,less than 42％ in the control group (x2=6.732,P=0.009).Conclusion Community health education could decrease pre-hospital delay for acute myocardial infarction,improve the rate of reperfusion therapy and decrease the overall incidence of severe complications during hospitalization.

Objective To study the effects of aerobic exercises on platelet function in patients with phase Ⅰ essential hypertension (EH). Methods Low-intensity aerobic exercises therapy was given to 36 patients with phase Ⅰ EH for three months. Changes of their blood pressure, heart rate, platelet aggregation rate (PAGTmax), alpha-granule membrane protein (GMP-140) and mean platelet volume (MPV) werer ecorded and compared to those in 36 normal healthy controls. Results As compared to those in controls,PAGTmax, level of GMP-140 and MPV were all increased in patients with phase Ⅰ EH before exercises therapy(t=15.221, 10. 916 and 16. 401, respectively, all P < 0. 01 ). After exercises therapy, 24-hour mean blood pressure decreased in association with reduction in PAGTmax to (0. 80±0. 05)% from (0. 88±0. 08) % (t=4. 323, P < 0. 05), level of GMP-140 decreased to ( 28±20) μg/L from (57±23 ) μg/L ( t=15.049, P<0.01) and MPV decreased to (9.0±0.9)fl from (9.1±0.9)fl (t=5.518, P <0.05) before it. But, there was no significant difference in these in dicators of platelet function in controls before and after exercise therapy (P>0.05). Conclusions Aerobic exercises therapy could be effective in lowering blood pressure in patients of mild EH with increased platelet activation, as well as inhibition ontheir platelet activation.

Objective To investigate the change of heart rate variability(HRV) in patients with white coat hypertension (WCH).Methods Participants were classified as essential hypertension (EH) group (n=35),white coat hypertension (WCH) group (n=35),normotension (NT) group (n=35) based on clinic and 24 h ambulatory blood pressure monitoring.The time and frequency-domain measures of HRV were measured by 24 h ambulatory electrocardiographic recording.Results Compared with NT controls,the standard deviation of normal-to-normal intervals (SDNN),rate-mean-square of the difference of successive RR intervals (RMSSD) and high frequence (HF) in the patients with EH and WCH were significantly decreased[SDNN:NT(132.2?21.5)vs EH(115.9?18.9)vs WCH(120.6?17.5)ms;RMSSD:NT(36.8?9.3)vs EH(28.6?8.9)vs WCH(27.5?8.5)ms;HF:NT(206.8?99.7)vs EH(159.5?86.6)vs WCH(161.1?84.5)ms2/Hz;all P0.05).Conclusion These changes in the parameters of HRV showed cardiac autonomic nerve dysfunction in white coat hypertensive patients.

Objective To investigate the role of glycogen synthase kinase-3β (GSK-3β) in the trafficking of NR1-containing N-methyl-D-aspartate receptor (NMDAR) and NR2B-containing NMDAR in the spinal cord in rats with incisional pain (IP) and remifentanil-induced hyperalgesia.Methods Twenty-four male Sprague-Dawley rats,aged 2-3 months,weighing 240-260 g,were randomly divided into 3 groups ( n =8 each):control group (group C),remifentanil group (group R) and GSK-3β inhibitor TDZD-8 group (group TDZD-8).A 1-cm longitudinal incision was made in the plantar surface of the left hindpaw in anesthetized rats.In group C,dimethyl sulfoxide (DMSO) 2 ml/kg was injected and then the normal saline (equal to the volume of remifentanil) was infused for 60 min via the caudal vein.In group R,DMSO 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg· kg- 1 ·min- 1 for 60 min.In group TDZD-8,TDZD-8 2 ml/kg was injected before IP was made and then remifentanil was infused at a rate of 1.2 μg·kg-1 ·min-1 for 60 min.Paw withdrawal threshold (PWT) and paw withdrawal latency (PWL) were measured 24 h before infusion of normal saline or remifentanil and at 2,6,24 and 48 h after intravenous injection.The rats were sacrificed after the last measurement of the pain threshold and L4-6 segment of the spinal cord was removed to determine the expression of NMDAR NR1 and NR2B subunits in cell membrane (s) and cytoplasm (i) in the spinal cord by Western blot analysis.The ratios of sNR1/iNR1 and sNR2B/iNR2B were calculated.Results Compared with group C,PWT was significantly decreased and PWL was significantly shortened,the expression of sNR1 and sNR2B was up-regulated,the expression of iNR1 and iNR2B was down-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly increased in groups R and TDZD-8 (P ＜ 0.05).Compared with group R,PWT was significantly increased and PWL was significantly prolonged,the expression of sNR1 and sNR2B was down-regulated,the expression of iNR1 and iNR2B was up-regulated,and the ratios of sNR1/iNR1 and sNR2B/iNR2B were significantly decreased in group TDZD-8 ( P ＜ 0.05).Conclusion GSK-3β is involved in the regulation of trafficking of NR1-containing NMDAR and NR2B-containing NMDAR from cytoplasm to cell membrane in the spinal cord in rats with IP and hyperalgesia induced by remifentanil.

砄bjectire: To investigate whether the disturbed occlusion can induce TMJ degeneration. Methods: 2 Rhesus female monkeys, 1 served as experimental animal and the other as the control, were included. Right mandibular first molar and left maxillary first molar of the experimental animal were extracted. Small strings were set at the missing space to pull the neighbor teeth inclined into the space and to occlude with opposite teeth in convex to convex relation. 8 months later condyles and discs of both animals were surgically obtained and prepared for scanning electron microscopy examination. Results: Gelatin like material was found over the condyle and disc surface of the control animal and obvious rigids were found on its articular surface. On the sagittal section of the condyle cells arranged in lines of each of the three layers of the soft tissue were observed. But on the top of the condyle surface of the experimental animal there was an area from media anterior to lateral posterior where the gelatin like material twisted or even disappeared here and there. There was an area where fibers were exposed. The soft tissue layers were thinner and the cellular layer was discontinued locally. The waves on the surface of middle and posterior part of the disc were disturbed and fossae like changes were found on the inferior surface. Conclusion: TMJ degeneration can be produced by gradually induced occlusal disturbance.

Objective To investigate the infection situation of group A human rotavirus(HRV)among the infants and young children with diarrhea in Lanzhou city,and to observe the relation between genders and age with the viral positive rate.Methods 2 378 samples of feces in the infants and young children with diarrhea were collected in this hospital from January to December 2013.The group A HRV antigen in samples was detected by using the immunochromatographic sandwich method.The positive rates of group A HRV infection in different months were analyzed and compared with the bacterial diarrhea;the viral positive rates in different genders and ages were analyzed.Results Among 2 378 detected feces samples,the average positive rate of group A HRV was 24.1% and the highest was 39.8% during the months from October to December;the average positive rate of bacterial diarrhea was 28.2% and the highest was 38.2% during the months from July to September.The positive rate of group A HRV was 25.5% in male children patients and 22.6% in female children patients,but the difference was not statistically significant (P >0. 05).The differences in the positive rates of group A HRV among different ages had statistical significance (P <0.05).The average positive rate was highest(29.0%)in children patients aged less than 2 years old,followed by the children patients aged 2 - <4 years old,which was 21.6%.Conclusion The group A HRV has the higher infection positive rate in winter and early spring,which mainly focuses on the children patients aged less than 2 years old.
