Objective To investigate the relationship between neck circumference and metabolic syndrome(MS) and its components in type 2 diabetes Methods A total of 272 subjects with type 2 diabetes were recruited.According to the diagnostic criteria of MS,all subjects were divided into MS group and non-MS group.According to neck circumference tertile,all subjects were respectively divided into male and female of three groups to analyze the relationship between neck circumference and MS and its components.Male:Q1＜38.8 cm,Q2=(38.8-41.3) cm,Q3≥41.4 cm;female:Q1＜34.0 cm,Q2=34.0-36.3 cm,Q3≥36.4 cm.The optimal cut-off points of neck circumference were used to determine the MS by ROC curve.Results (1) Compared with non-MS group,subjects in MS group had significantly higher neck circumference((38.3±3.2)cm vs.(36.1±3.7) cm),waist circumference((94.1±8.4) cm vs.(82.7±10.8) cm),waist-hip ratio(0.93±0.06 vs.0.88± 0.08),body mass index ((26.2 ± 2.9) kg/m2 vs.(23.9 ± 3.5) kg/m2),fasting plasma glucose(9.0(6.7-11.5) mmol/L vs.7.7(5.9-10.2) mmol/L),systolic pressure(140(130-150) mmHg vs.130 (120-130) mmHg),diastolic pressure (80 (80-90) mmHg vs.80 (75-85) mmHg),triglycerides (1.9(1.4-2.8) mmol/L vs.1.2 (0.9-1.5) mmol/L),low-density lipoprotein cholesterol (LDL-C) ((3.3 ± 1.0)mmol/L vs.(3.0±0.9) mmol/L) and blood uric acid((322.7±90.1) mmol/L vs.(270.3±82.3) mmol/L),and the differences were significant(t or Z=-4.843,-8.622,-5.157,-5.592,-2.729,-5.723,-3.847,-6.856,-2.123,-4.545;P＜0.05).While the level of total cholesterol((2.7±2.8) mmol/L vs.(4.9±1.3)mmol/L) and high-density lipoprotein cholesterol (HDL-C) (1.0 (0.8-1.2) mmol/L vs.1.2 (1.1-1.5)mmol/L) were decreased,and the differences were significant (t or Z =-2.269,-7.068;P ＜ 0.05).(2)Compared with those with lowest tertiles(Q1 ＜38.8 cm) of neck circumference,male subjects with highest tertile (Q3≥41.4 cm) had higher level of waist circumference((97.8±8.6) cm vs.(89.9±8.5) cm),waist-hip rati (0.96±0.07 vs.0.93±0.06),body mass index((27.4±2.1) kg/m2 vs.(23.8±2.3) kg/m2),blood uric acid ((374.0±85.6) mmol/L vs.(305.8±73.6) mmol/L),and the differences were significant(P＜0.05).While age((52.1±10.7) years vs.(60.4±11.8) years) andHDL-C((1.0±0.3) mmol/Lvs.(1.2±0.5) mmol/L) were decreased,and the differences were significant (P＜0.05).Female subjects with higher tertile (Q3 ≥ 36.4 cm) had significantly higher level of waist circumference ((96.8 ± 10.1) cm vs.(79.5 ± 8.5) cm),waist-hip ratio(0.94±0.07 vs.0.86±0.06),body mass index((28.5±3.1) kg/m2 vs.(21.9±2.2) kg/m2),blood uric acid((295.2±94.3) mmol/L vs.(244.6±62.3) mmol/L),the frequency of MS(83.3％(40/48)vs.21.7％(10/46)) than with lower tertile(Q1＜34.0 cm).(3) Logistic regression analysis showed that neck circumference (β =0.187,P ＜ 0.001) was an independent risk factor of MS (y =0.187x-6.613).(4) The optimal cut-off points of neck circumference to MS were 40.1 cm (AUC =0.682,P=＞0.008) in male,and 35.3cm (AUC =0.766,P＜ 0.001) in female.Conclusion Neck circumference increases when type 2 diabetes patients with MS.Neck circumference is an independent risk factor for MS,which can be used as an indicator to evaluate MS.

Objective To compare the comprehension monitoring in reading between students with and without hearing impairment. Methods An error detection paradigm and an eye-movement recordings method were used in two samples of hearing impairment students and no-hearing impairment students with passages that contained inconsistencies with interval 2 sentences, 4 sentences, 6 sentences and 8 sentences. Results The scores of reading comprehension, the index of tradition monitoring and the index of eye movement were lower in the hearing impairment students than in the no-hearing impairment students (P<0.05). Conclusion The comprehension monitoring ability in reading is poor in the hearing impairment students.

Objective To investigate the change and significance of electrocardiogram and myocardial damage index in patients with acute organophosphorus pesticide (AOPP).Methods 71 hospitalized patients in EICU with AOPP from January 2000 to June 2006 were recorded.The patients were divided into 3 groups: mild poisoning group (n=18),moderate poisoning group(n=22) and severe poisoning group (n=31).Electrocardiogram(ECG), serum creatine kinase(CK), serum creatine kinase isoenzyrne MB(CK-MB),lactate dehydrogenase(LDH) and TnI were detected,the relation between the above-mentioned indexes and the toxical degree were analyzed.Results Abnormal ECG had a rasied tendency along with increase of the poisoning degree.The incidence of Ⅱ~Ⅲ atrioventricular block, atrial premature beats, ventricular premature contraction, ventricular tachycardia and ventricular fibrillation in severe poisoning group significantly increased compared with that in mild poisoning group and moderate poisoning group(P

Autophagy is a vacuolar process of cytoplasmic degradation by lysosome which ubiquitously occurring in all eukaryotic cells. The researches of autophagy have made great progress with the development of the yeast model and genetic technology. This review will summarize the determination of autophagy, its relationship with apoptosis and its role in the tumor treatment in order to give a comprehensive understanding of the function of autophagy.

Objective To resolve the problem that qualified chloramine T was difficult to purchase for some basic laboratories Methods Using the solution of available chlorine prepared by bleaching power instead of chloramine T, the method for determination of cyanide in drinking water was improved Results The data obtained by this assay accorded with Beers Law in the range of 0～2 0 ?g/25 ml cyanide The detection limit,relative standard deviation,and recovery rate were 0 04?g,2 69%～3 09% and 97 50%～99 17% respectively Conclusion This method for determination of cyanide in drinking water was simple and easy to operate and presented good precision and accuracy

Objective To investigate the early predictive indexes of curative effect of acute respiratory failure(AFR) treated with noninvasive bilevel positive airway pressure(BiPAP) ventilation.Methods Sixty-eight patients with AFR were treated with BiPAP ventilation.According to the therapeutic outcome,patients were divided into success group and failure group,and the distributions of ages,acute physiology and chronic health evaluation(APACHEⅡ) score,consciousness level as well as arterial blood gas(ABG) measurement before and after the treatment with BiPAP ventilation were compared between the two groups.Results There was statistical difference in the ABG levels of pH and PaCO_2 after 1 hour's treatment with BiPAP ventilation(P0.05).Conclusion The levels of pH and PaCO_2 after 1 hour's treatment with BiPAP ventilation are valuable markers for curative effects in early stadge.If the levels of pH and PaCO_2 fail to improve,the treatment with intubation may be necessary.
