Objective To investigate the effects of transcranial electrotherapy stimulation (TES)on patients with generalized anxiety disorder (GAD). MethodsA total of 62 patients with GAD were randomly divided into two groups,the study group (treated with TES and venlafaxine) and the control group (treated with venlafaxine only).TES was administered 1 time per day for 14 days,while venlafaxine was administered with oral intake of 75-150mg/d for 4 weeks.The clinical effects were assessed by using Hamilton anxiety scale (HAMA).ResultsThere was no difference between the two groups in average HAMA total scores,psychic and somatic factor scores before the treatments (P ＞ 0.05).The effective rate of study group was significantly higher ( P ＜ 0.05 ) at the end of the 1 st week after treatment than,but similar at the end of the 2nd and 4th week after treatment (P ＞ 0.05 ) to that,of control group,with regard to HAMA total score and psychic factor score.With regard to the HAMA somatic factor score,the effective rate of study group was not significantly different from that of control group at the end of the 1st,2nd and 4th week after treatment (P ＞ 0.05).ConclusionTranscranial electric stimulation in conjunction with venlafaxine may improve the symptoms of anxiety of patients.

Objective To explore the strategy of emergency medical rescue of the massive crowd in general hospital during spring festival with snow disaster. Method The clinical data of 20 966 emergency cases were analyzed retrospectively from 22 Jan,2008 to 6 Feb, 2008 with snow disaster, and concerned about the ratio of different diseases, the character of pre-hospital care and the contrast between emergency medical treatment and routine work. Results The accidence of respiratory disease ( 57.3 % ) was followed by gastrointestinal ( 25.5 % ) and trauma (6.2% )during the emergency medical treatment, and surgical trauma, syncope, coma and convulsion were the most common symptoms, also in some conditions, but empties returning was 30.3% . Similar to the above situation, the extremities (56%)and head injury (24%)were most commonly in the hospital emergency department. The incidence of falling accidents was high( 35.7 % ), and two of them were dead due to trauma on died of being trampled, and on the other was electrothermal burn and falling. Conclusions The general hospital is very important in emergency medical treatment, and it should be ready to tackle the emergency disaster, in order to reduce the loss to minimum.

In order to strengthen the education for university students’all-round devel-opment,and to improve the quality of teaching,Shantou University,by making good use of higher education resources,built a digital campus consisting of virtual classrooms based on advantage of computer and Internet network environment,and plenty of general education programs were carried out.The teaching practice showed that virtual classroom,as a network platform,played an important role in general education programs.

Objective To study the efficiency of tele-consultation on Internet with transmitting realtime 12-lead ECG carried out by the Chest Pain Center evaluated by the length of time required for the emergency percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI).Methods A total of 435 STEMI patients treated by emergency PCI were divided into the group A (n =98,admitted in 2010),group B (n =114,admitted in 2011) and group C (n =223,admitted in 2012).Data were collected before (2010) and after establishment of the Chest Pain Center (2011 to 2012) including the length of time elapsed from onset of symptoms to the first medical contact (FMC),the length of time required from FMC to the intra-aortic balloon inflated (FMC-2B) and the length of time required from entering the gate of hospital to the intra-aortic balloon inflated (D-2B).Measure data were described with non-normal median and interquartile intervals.Comparisons were made among groups with rank sum test.Results The median time of D2B of three groups were 107,78 and 59 mins in groups A,B and C,respectively.The differences in D2B among three groups were significant (P =0.000).The time of the D2B was shortened significantly because of the patients transferred to the hospital with a variety of ways (P =0.008).However,the length of D2B time was not significantly changed (P =0.846) when patients came to the hospital all on themselves.The median times from symptom onset to FMC in the group A,group B and group C were 112,62 and 78 mins.and the differences among three groups were not statistically significant (P =0.368).The median times of FMC2B in three groups were 287.0,313.5 and 421.8 mins,respectively,and there were no significant differences (P =0.135).Conclusions The establishment of the Chest Pain Center and Internet of things can effectively shorten the duration of D2B in STEMI patients.However,the reduction of time length from the symptom onset to reperfusion must rely on the coordination between communities and health care system.

Objective:To develop adjustable peel force tester with peel angle from 0° to 180°,so as to realize the test for the performance of interface adhesion of wearable electronic products under multi angles.Methods:The rotating platform of angle adjustment component was used to realize free adjustment of peel angle from 0° to 180°.A method of peel test procedure based on the peel force tester with full-angle was established,and the comparative experiment between that and tensile testing machine was conducted.The peel tests of various kinds of wearable electronic products were conducted under peel angle of 45°,90° and 180°.Results:The test results of the peel force tester with full-angle were consistent with those of the tensile testing machine,which function opposed reliability.The peel test results of more than 10 wearable electronic products indicated that the peel force tester with full-angle could effectively determinate the performance of interface adhesion.Conclusion:The peel force tester with full-angle can effectively appear the performance of the interface adhesion of wearable electronic products,which provides basis for establishing the standard of peel test of wearable electronic products.

Objective To explore the correlation between serum lipoprotein-related phospholipase A2 (Lp-PLA2), cystatin C (Cys-C) levels and disease severity in patients with hepatitis B cirrhosis (HBC). Methods Clinical data of 110 HBC patients in the hospital from October 2017 to May 2019 were retrospectively analyzed. According to Child-Pugh classification criteria of liver cirrhosis, they were divided into grade A (n=42), grade B (n=37) and grade C groups (n=31). Another 30 healthy controls during the same period were enrolled as control group. The levels of serum Lp-PLA2 and Cys-C were detected. And their correlation with disease severity was analyzed. Results Levels of serum Lp-PLA2 and Cys-C in HBC group were higher than those in control group (P<0.05). The levels of serum Lp-PLA2 and Cys-C were the highest in grade C group, followed by grade B group and grade A group (P<0.05). The areas under the ROC curve (AUC) of serum Lp-PLA2 combined with Cys-C for evaluating grade A and B, grade B and C HBC were 0.875 and 0.837, which were higher than those of Lp-PLA2 (0.772, 0.750) and Cys-C (0.750, 0.691) alone (P<0.05). Spearmann rank correlation analysis showed that levels of serum Lp-PLA2 and Cys-C were positively correlated with disease severity (r=0.659, 0.561, P<0.05). Conclusion The levels of serum Lp-PLA2 and Cys-C are significantly increased in HBC patients, which are gradually increased with the aggravation of HBC. The two indexes are positively correlated with disease severity, which are of diagnostic efficiency for the classification of liver cirrhosis.
