Objective To investigate compliance rate of clinic appointments among residents contracting family doctor service and its influencing factors.Methods Total 1 442 clinic appointments among residents contracting family doctor service in Yuetan community were investigated by face to face questionnaire.Results Among 1 442 clinic appointments in Yuetan community health service center in June 2015,563 were kept with a compliance rate of 37.2％.There were significant difference in compliance rate among the residents with difference degree of education (OR =1.461,95 ％ CI:1.296-1.646,P =0.000),between those with and without chronic diseases(OR =2.009,95％ CI:1.136-3.550,P =0.016),with and without receiving first contact care at community (OR =1.360,95％ CI:1.036-1.785,P =0.027),with and without satisfying with family doctor service (OR =1.315,95 ％ CI:1.060-1.630,P =0.013),with and without recognizing clinic appointment system (OR =2.765,95％ CI:2.142-3.569,P =0.000).Among the 906 failed appointments,the reasons were forgetting the appointment in 525 (57.9％),missing the date in 124 (13.7％),time conflict in 92 (10.2％),not bring reservation form in 85 (9.4％),being hospitalized or engaging in other medical service in 41 (4.5％) andneglecting appointment system in 39 (4.3％).Conclusion Compliance rate of clinic appointments among residents contracting family doctor service is lower,and necessary measures should be taken to increase the compliance rate.

Objective:To evaluate the occlusal function of patients with Class ⅡDivision 1 malocclusion.Methods:T-Scan II system 4.02 was used to record total occlusal force(TOF),asymmetry index of occlusal force(AOF),number of occlusal contacts(NOC),asymmetry index of occlusal area(AOA),center of force(COF),maximal movement of COF(MMCOF),occlusal interference index(OII)of 26 Class ⅡDivision 1 malocclusion in the intercuspal position(ICP)comparing with 26 normal occlusion.Results:TOF in Class ⅡDivision 1 malocclusion was significantly smaller than that in normal occlusion(P0.05);AOF,AOA,COF,MMCOF,OII in ClassⅡ1 were significantly higher than those in normal occlusion(P

The thermal characters such as temperature field, temperature grads and cooling power are very important for sur geons to estimate and improve curative effect. The freezing experiment around a 3.4mm cryoprobe was conducted and a multi dimensional numerical model based on enthalpy method and solved by finite element scheme for the freezing process of simu lative biological tissues during cryosurgery is presented. The results of the numerical solution were validated against experimen taal data .The utility of the numerical solution for the design and application of c ryodevices is demonstrated.

Objective To investigate the alterations and molecular mechanism of neural cell apoptosis after frontal lobe sharp injury in infant rats.Methods Brain damage was induced by frontal lobe sharp injury.dUTP nick end labeling(TUNEL) method was used to detect cell apoptosis after brain injury,and immunohistochemistry was used to detect the expression of Bax,Bcl-2 proteins in and around the area of injury,respectively.Results The apoptosis cells were found as early as 1 hour and reached a peak at 24 hours post-injury,then gradually diminished until 120 hours when only few apoptosis cells presented.The expression of Bax and Bcl-2 proteins increased significantly 1 hour after frontal lobe injury.Bax protein reached its peak at 12 hours while Bcl-2 protein reached its peak at 1 hour post-injury.The ratio of Bax to Bcl-2 increased after lesion with peak at 24 hours,and then decreased thereafter.At 120 hours,very weak expression of Bax and Bcl-2 protein detected.There were few Bax and Bcl-2 positive cells in frontal lobe cortex in blank control and sham operation group.Conclusions Cell apoptosis exists after frontal lobe sharp injury in infant rats and the change of the number of apoptotic cells is correlated with time course of post-injury.The ratio of Bax to Bcl-2 may play a vital role in cell apoptosis.

Objective To investigate the gait differences among patients with Alzheimer's disease (AD) and mild cognitive impairment(AD-MCI) and the person with normal cognitive function,and analyze the reasons for the abnormal gait.Methods Eighty patients were included and divided into 3 groups according to the cognitive status:noncognitive impairment (NCI group,n =30),patients with mild cognitive impairment (AD-MCI group,n =29),Alzheimer's disease (AD group,n =21).The mini-mental state examination (MMSE),the Montreal Cognitive Assessment (MoCA),Addenbrooke's Cognitive Examination (ACE-R),the connection test (TMT-A),Digit Span Test(DST),activities of daily living questionnaire(ADL) and associated gait and balance scale (5 times sit to stand test (FTSTT),3 m walking test (TUG),Berg balance scale) were used to evaluate all research objects in each group.Results There were significant differences in NCI group compared with AD-MCI group and AD group in terms of FTSTT,TUG,Berg balance Scale and leg speed((9.59±2.39) s vs.(13.71±4.65) s vs.(14.15±4.20) s,(7.70±1.58) s vs.(11.13±3.02) s vs.(11.35±4.43) s,(54.20±1.56) points vs.(48.17±4.93) points vs.(48.10±5.46) points,(82.12±22.79) cm/s vs.(57.49± 14.89) cm/s vs.(57.70±14.68) cm/s;P＜0.05).There were significant differences in NCI group compared with AD-MCI group and AD group in terms of MMSE,MoCA,ACE-R,TMT-A,DST((28.67±1.27) points vs.(26.76±2.59) points vs.(21.86±5.29) points,(26.03±2.58) points vs.(22.39±5.05) points vs.(16.90±5.05) points,(85.80±5.90) points vs.(78.03±7.58) points vs.(60.95± 13.99) points,(12.66±5.36) s vs.(18.99 ± 11.46) s vs.(30.49±26.98)s,(18.60±4.64) points vs.(15.94±4.76) points vs.(12.86±5.23) points;P ＜0.05).Conclusion Gait disorder might be an early sign for cognitive impairment.

Objective To investigate the prevalence and frequency of the common mutations in Uigur non-syndromic deafness group in Xinjiang Uigur Autonomous Region of China, by means of screening nine mutations of four known deafness genes. Methods One hundred eighty-four Uigur patients and 133 Han patients with non-syndromic hearing loss were enrolled in this study. The screening was performed on GJB2, GJB3, mtDNA 12S rRNA and SLC26A4 deafness genes of 35delG, 176de116,235de1C ,299-300delAT,538C ＞ T, 1555A ＞ G, 1494C ＞ T,2168A ＞ G, IVS7-2A ＞ G in these two groups, by means of genic microarray. Results The totlal mutation rate found in the Uigur deafness groups was 12. 50%, significantly different from that in the Han deafness groups (30. 83% ,χ2 = 16. 092 ,P ＜0. 01 ). The GJB2 mutation rate in the Uigur deafness groups was 9. 24%, not significantly different from that in the Han deafness groups ( 14. 29% ,χ2 = 1. 953 ,P ＞0. 05 ). The mutation rate of SL C26A4 was 1.63% and 13.53% respectively in Uigur and Han deafness groups, and has significant difference (χ2 = 17. 683, P ＜ 0. 01 ). The mt DNA 12S rRNA mutation rate in the Uigur deafness groups was 1.63%, not significantly different from that in the Han deafness groups (3.01%, χ2 = 0. 175, P ＞ 0. 05 ). The GJB3 mutation rate of these two deafness groups was very low, shown as 0. 75% and 0 respectively. Conclusions The mutation rate of common deafness genes is lower in the Uigar nonsyndromie deafness group, and the mutation rate of SLC26A4 genes is significantly lower than that in the Han deafness groups. The most common mutation in four known deafness genes is GJB2, whose favorite spots are 235delC and 35delG.

Objective To investigate the brain protective effect of isoflurane preconditioning on the rat liver against ischemia-reperfusion through determining the content of S-100β protein in peripheral blood in combination with mitochondrial ultrastructure in rat brain.Methods A total of 45 SD rats were randomly divided into three groups,sham group (group S):the only separation of the hepatoduodenal ligament,but did not block the hepatic portal blood supply; ischemia-reperfusion group (group I/R):liver ischemia 60min,reperfusion 120 min; isoflurane preconditioning group (group ISO):60 min before liver I/R,ISO pretreatment for 30 min,elution in the air after 30 min; 24 h after recirculation the forebrain tissues were rapidly removed.The changes of mitochondrial ultrastructure were observed by electron microscopy.The content of S-100β protein in serum was measured before ischemia and reperfusion 120 min through the application of Elisa kit.Results Marked swelling of mitochondria with disrupted cristae and damaged matrix were observed in group I/R,while relative intact mitochondria were seen in sham and ISO groups.The content of S-100β protein in serum was significantly higher in I/R group [(1.52 ±0.26) μg/ml] than in sham [(0.31 ±0.05)μg/ml] and ISO [(0.79 ± 0.21) μg/ml] groups (P ＜0.05).Conclusions The liver ischemia-reperfusion may injure the brain of the rat and isoflurane preconditioning can protect the rat brain from injury.
