Objective To compare the effect of different general anesthesia method on preoperation cognitive function in elderly patients.Methods According to the digital table,82 elderly patients(non cardiac surgical operation) were selected and divided into the two groups,each group 41 cases.The group A was given to sufentanil combined with propofol intravenous injection anesthesia,and the group B was given to sevoflurane inhalation anesthesia.The cognitive function of patients of two groups in preoperative,postoperative 3h,6h,24h were assessed by simple intelligence scale(MMSE),and the indicators of postoperative recovery were evaluated.Results The postoperative sleep time [(6.9 ± 1.2) min],language ability recovery time [(9.8 ± 2.2) min] in the group A were all higher than those of group B (t =6.687,5.640,all P ＜ 0.01).The MMSE scores in group A after 3h [(17.1 ± 2.2) points],6h [(19.6 ±2.7)points],24h[(22.4 ±2.3) points] were lower than those of group B(t =10.026,6.229,5.082,all P＜0.01).And the PCOD rate in group A after 24h was 36.6％,which was higher than 17.1％ in group B(x2 =3.98,P ＜ 0.05).Conclusion The inhalational anesthetic methods has more quickly postoperative recovery,lower incidence of cognitive dysfunction,better clinical effects.

years ago, Noma first applicated the patch\|clamp technique to CN\|treated mamammalian heart cells,evealed specific K + channels which were depressed by intracellular ATP at level greater than 1 mM.He suggested the ATP-sensitive channels are important for regulating cellular energy metabolism in the control of membrane exitability.Recent studies supported the hypothesis and suggested that ATP-sensitive channels play an important role in hypoxia,myocardial ischemia/reperfusion and is chemic preconditioning.

AIM: To determine the effects of phospholipase A 2 (PLA 2) and K ATP on rat ischemia/reperfusion(I/R)-induced arrhythmia. METHODS: Myocardial ischemia and reperfusion were produced by occlusion and reirregation of the left anterior descending artery(LAD). An inhibitor of PLA 2, 5,5-dithio-bis(2-nitrobenzoic acid) (DTNB) (16 mg /kg), a K ATP opener pinacidil (0.2 mg/kg), a K ATP blocker glibenclamide (0.3 mg/kg) was used 5 min prior to 10 min regional ischemia and 10 min reperfusion. RESULTS: DTNB (16 mg/kg) reduced the scores of arrhythmia, creatine kinase (CPK) and lactate dehydrogenase(LDH) (P

The public ethics consciousness,with medical ethics included,fundamentally depends on the gradual improvement in the self-identity of human as objective itself.However,the improvement of humanistic consciousness is a long and painful process.Former recognition of historical culture,including the humanistic ideal in traditional Chinese ethical thoughts and systemic rational thoughts in modern western society,mainly employs transcendental test of abstract anthroposophy as its cultural premise,superficially enhancing certain individuals and their thoughts,motives,and objectives to historical ontology,but actually resulting in the absence of human individuals in realistic history.The self-conscious improvement of human-oriented public ethics can only be realized by the subjective humanistic consciousness which undergoes the regression from axiology,epistemology,to existence theory,making human realize that they themselves are the utmost purpose of all values and significances.

Objective To investigate the multi-organ lesions and the occurrence of coronary aneurysms in children with Kawasaki disease(KD).Methods 92 pediatric inpatients with KD were enrolled and studied.The organs involved and coronary aneurysms(CAA)were determined by checking blood routine,urine routine,stool routine,chest X-ray,electrokardiogram,liver function,echocardiogram,and clinical manifestation.Results The incidence of various organs involved in 92 patients with KD:heart 71.7%;lung 37.0%;liver 34.8%;brain 12.0%;kidney 18.5%;gastrointestinal tract 15.2%;spleen 2.2%;gallbladder 1.1%;joints 9.8%.In addition,the rate of two organs involved simultaneously was 40.2%,three and more 34.8%.The incidence of CAA in brain lesion,joints lesion and pericardial effusion complications of KD was 45.5%,44.4%,and 41.7%,respectively.Conclusions The data shows that the incidence of heart involvement in the sick-children with KD is highest,and other organs,such as lung,liver,kidney,gastrointestinal tract,brain and joints are involved in turn.The incidence of 2 and more organs involved simultaneously amounts to75.0%.CAA is the most serious complication of KD.Our study suggests that the incidence of CAA is obviously high in these lesions of brain,joints and pericardial effusion involvement in KD.

OBJECTIVE:To establish a method for the determination of dissolution of Xiaocaihu pill,and compare the differ-ence of preparation from different manufacturers. METHODS:Using 0.1 mol/L HCl as dissolution medium,rotating basket method was used to determine the dissolution of preparations. HPLC was adopted to determine the content of baicalin:column was TSKgel ODS C18 with mobile phase of methanol-water-phosphoric acid (65∶35∶0.7,V/V/V) at a flow rate of 1 ml/min,detection wave-length was 280 nm,column temperature was 30 ℃,and injection volume was 5 μl. RESULTS:The linear range of baicalin was 0.488-124.8 mg/L (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recovery was 100.14%-104.78%(RSD=1.58%,n=9). The average t50(50% dissolution time)of baicalin was 85.81 min. CONCLUSIONS:The method is simple with good precision,stability and reproducibility,and can be used for the dissolution determination of Xiaocaihu pill. Xiaocaihu pill from different manufacturers shows great differences,both preparation formulation and clinical use should attach importance to the dissolution of solid preparations.

Objective To evaluate the application value of virtual touch tissue quantification(VTQ) in the differential diagnosis of small breast lesions.Methods Fifty-six patients with sixty-nine small breast lesions whose largest diameter were less than or equal to 1 cm were evaluated with VTQ.The shear wave velocity (SWV) of the lesions and normal breast tissue were measured to analyze the diversity of different pathological types lesions of SWV and to find the optimal cut-off points using ROC curve to predict small breast cancer.Resuits The mean SWV(Vm) and the ratio (mean of lesions and normal tissue) of SWV (Vm1/Vm2) in benign group was (2.93 ± 1.32)m/s,1.79 ± 0.63,respectively,and that in malignant group was (5.65 ± 2.63) m/s,3.61 ± 1.35,respectively,there were statistically significant differences between benign group and malignant group (t test,P ＜0.05).The cut-off point of Vm was determined as 4.43 m/ s,the sensitivity,specificity and accuracy of diagnosing breast cancer were 80.5％,89.3％,92.8％,respectively.The cut-off point of Vm1/Vm2 was determined as 2.37,the sensitivity,specificity and accuracy of diagnosing breast cancer were 76.9％,81.2％,89.9％,respectively.Conclusions VTQ technique can provide helpful information in the differential diagnosis of small breast lesions.

Objective:To analyze the awareness rate of obesity risk factors among children and adoles-cents, and to provide the basis for preventing their obesity. Methods: The students selected by using stratified cluster sampling method, were measured for the body height, weight, and waist circumference, and were surveyed for the awareness rate of obesity risk factors by using the questionnaire. The distribu-tion characteristics of awareness on obesity risk factors were analyzed. Results: The awareness rate of obesity risk factors was 74 . 1%, and there was no significant difference on the awareness rate of obesity risk factors between the males [71. 2% (247/347)] and females [77. 2% (257/333)], the abdominal obesity students [73. 5% (202/275)] and non-abdominal obesity students [74. 6% (302/405)], the overall obesity students [74. 3% (185/249)] and non-overall obesity students [74. 0% (319/431)], re-spectively. However, the awareness rate of obesity risk factors among the primary school students was 81. 9% (272/332) that was higher than that of the middle school students [66. 7% (232/348)] (P<0. 05). Compared with the primary school students, the non-awareness risk of obesity risk factors would in-crease among the middle school students (OR=2. 23, P<0. 05). Conclusion:The overall awareness rate of obesity risk factors is not high among children and adolescents, especially among middle school students.

Objective To study the current prevention and control status of iodine deficiency disorders (IDD) and learn the current situation of iodized salt consumption at household level in non-high iodine areas in 2015,this surveillance was conducted.Methods In 2015,according to National Surveillance Program on Iodine Deficiency Disorders,the surveillance was conducted at county level in 31 provinces,municipalities,autonomous regions (provinces) and Xinjiang Production and Construction corps (Xinjiang Corps).In each county city,district,banner (county),5 townships were randomly selected according to their sub-area positions of east,west,south,north and center;4 villages were randomly sampled in each chosen township;15 households were randomly selected in each chosen village.Edible salt sample was collected from each household.The iodine level in salt was determined by direct titration;the salt samples from Sichuan and other enhanced salt samples were detected by arbitration.Results There were totally 2 840 counties that reported the surveillance data.In total,849 193 salt samples were examined,including 845 906 salts determined by direct titration and 3 287 samples determined only by semi-quantitative detection.Weighted by population,the national coverage rate of iodized salt was 98.37％.At provincial level,the coverage rate of iodized salt was higher than 95％ except Tianjin,Shanghai and Shandong.At county level,2 669 counties had a coverage rate of iodized salt higher than or equal to 95％,171 counties were lower than 95％,and 31 counties were less than 80％.The national consumption rate of qualified iodized salt was 94.57％ (except 11 counties in Tibet).At provincial level,the consumption rate of qualified iodized salt was higher than 90％ except Shanghai (66.84％),Tianjin (79.14％),Tibet (82.09％) and Qinghai (89.22％).At county level,totally 2 633 counties had a rate of qualified iodized salt higher than 90％,and 196 counties were lower than 90％.The mean of iodine content in iodized salt was (25.37 ± 4.57) mg/kg.At provincial level,the means of iodine content in iodized salt were in the range of 23.51-28.95 mg/kg and the variable coefficient (CV) was in the range of 12.17％-27.37％,the CV was higher than 15％ in 24 provinces and Xinjiang Corps.Conclusions The coverage rate of iodized salt and the qualified iodized salt at national level are in a good condition.However,the problem of non-iodized salt is still serious in some provinces.
