Despite efforts to develop treatment technology for cardiac arrest (CA), CA incidence and mortality rates are still high.[1,2] A recent study of CA patients in emergency departments revealed that the incidence of CA is increasing annually, and the in-hospital survival rate of CA patients is only approximately 28.7%.[3] Echocardiography has been widely used as an important monitoring tool in critical care and helps to identify the cause of shock, monitor hemodynamics, and guide fluid therapy utilization.[4] One study reported that approximately one-third of patients underwent formal echocardiography during hospitalization in the intensive care unit (ICU).[5]

The proposal to promote the commercialization of new insect-resistant GM cotton,GM corn and other major products in 13th Five Year Plan on National Science and Technology Innovation ,has put forward a test to the government's ability to manage GM crops cultivation.Only a few species of GM crops,not including food crops,have been commercialized in China,we lack experience in GM crops cultivation management.Taking USA,where the farmers cultivate huge areas of GM crops,as a comparison object,the examination and approval procedures before cultivation,GM crop growers' obligation of the management,the methods to reduce mingling of GM crops and non-GM crops are compared.And concludes that the differences in legal status of GM crops,the intellectual property regime and labeling regulation,the ability of relative stakeholders to implement segregation measures and bear loss lead to different regulation on GM crops cultivation management in USA and China.The government combine the domestic current situation of the agricultural environment in our country,and focus on substantial risk in the safety management of GM crops in cultivation management is advised.The competent department of agriculture,researchers and seed traders should work together to help guide growers to avoid the economic disputes due to mingling and reduce the impact on the ecological environment.

Objective To analyze the value of PET/CT for diagnosis of recurrence and metastasis of dif-ferentiated thyroid carcinoma ( DTC) .Methods 65 patients with DTC in Thyroid Surgery Department of the First Affiliated Hospital of Zhengzhou University from Dec .2005 to Jan.2015 were collected.Based on the values of serum thyroglobulin(Tg),the patients were divided into 2 groups.29 cases with positive Tg were the observation group and 36 cases with negative Tg were the control group .All patients underwent PET/CT examination one year after surgery.Patients with positive findings from image studies underwent surgical excision and postoperative pathological diagnosis .Clinical data of the 2 groups were then summarized and discussed .Results There was no significant difference on the general conditions between the 2 groups(P>0.05).Tg values were statistically dif-ferent 6 months and 1 year after surgery between the 2 groups(P<0.05).Tg values of both groups decreased 1 year after surgery, but without statistical difference (P>0.05).9 cases in the observation group and 1 case in the control group had positive findings on image study .All the cases with cervical lymph nodes presented as high uptake of 18 F-FDG.All patients who had positive findings on PET/CT underwent surgical removal of the abnormal lymph nodes which confirmed by pathology as lymph node metastasis .Conclusion PET/CT is very important for diagno-sis of recurrence and metastasis on Tg(Tg>2μg/L)positive,131I Dx-WBS imaging and US negative patients.

In this study, based on its enhancement effect on resonance light scattering (RLS) of fluorosurfactant (FSN)-capped gold nanoparticles (GNPs), we reported a simple approach for the rapid sensing of captopril. Under optimum conditions, the lowest detectable concentration of captopril through this approach (S/N=3) was 0.01μg/mL. The calibration curve was linear over the range of 0.08-4.0μg/mL for the detection of captopril. The recoveries of captopril were found to fall in the range between 99% and 100%. We have validated the applicability of our method through the analyses of captopril in pharmaceutical formulations. Good agreements were obtained for the determination of captopril between the present approach and official method.

OBJECTIVE:To investigate the analgesia effect of low-dose ketamine combined with sufentanil after radical sur-gery of esophageal cancer. METHODS:Totally 153 patients of pre-implementation esophageal cancer surgery were randomly divid-ed into group A,B and C. After induction of anesthesia in patients in each group,patients in group A administered sufentanil 2 μg/kg;group B were treated with sufentanil 2.5 μg/kg;group C were treated with sufentanil 2 μg/kg + ketamine 85 μg/(kg·h). Visual analog(VAS)score and Ramsay score before and after anesthesia 4,8,16,24 and 48 h,analgesia pump pressing times and inci-dence of adverse reactions in each group were observed. RESULTS:Ramsay score in 4,8 and 16 h in each group were significant-ly higher than before anesthesia,the differences were statistically significant(P<0.05),however,compared with before,there was no significant difference in the Ramsay score in 48 h among each group(P<0.05);VAS scores in each group(except for group C in 48 h) at each time point were significantly higher than before,group C
