Research articles in the domestic bilingual teaching on the basis of the status, and presents a stratification analysis of thinking methods,to explore the notion of bilingual teach-ing,and the hierarchical structure of teacher,teaching materials,students,and evaluation of the bilingual teaching,and probe into the reform of bilingual teaching.

objective To study the changes of reticulocyte micronueleus(MN-RET)from peripherai blood and polychromatic erythrocyte mieronucleUS(MN-PCE)from bone marrow in mice following exposure to X-rays in order to provide an experimental basis for exploring possible hish-throughput radiation biodosimeter.Methods Male ICR mice were whole-body irradiated with 0,0.5,1,2,4 and 5 Gy at a dose rate of 0.488 Gy/min.MN-RET from peripheral blood wag scored with FCM and MN-PCE from bone marrow was scored with manual microscopy at 24,48 and 72 h post-irradiation.Results Both MN-RET and MN-PCE rates increaged with doses in the range of 0-5 Gy at 24,48 and 72 h after WBI.The dose-response relationship can be fit with linear equations(t=10.26-25.77,P<0.05).The correlation coeffcients between MN-RET from peripheral blood and MN-PCE from bone mallow were highly significant(r=0.986-0.996,P<0.05).Conclusions In view of its simplicity,accuracy and high throughput capacity,FCM scoring of peripheral blood MN-RET may be a candidate for radiation biodosimetry,More work should be carried out on human specimens to investigate this possibility.

0.05).The apoptotic percentage was increased significantly after X-rays irradiation with the dose of 6 Gy(P

Objective To increase the ability to recognize the characteristic MRI features of multiple sclerosis (MS) in the spinal cord. Methods Fifteen patients with MS underwent MR examination of the cervical spine. The MS plaques were evaluated for lesion location, length,size on cross-section and lesion enhancement. MRI features of intraspinal tumor of spinal cord, cervical spondylopathy of myeloid form and transverse myelitis were analyzed and compared. Results The lesion mainly developed in cervical cord in the 15 patients. The lesions were less than five vertebra body in length. MRI features showed that involved cord segment was mild swollen with smooth periphery in sagittal section;the plaques showed iso-mild hypointense on T 1WI and hyperintense on T 2WI; the plaques were located peripherally and occupied less than 50%of the cross-sectional area of the cord; the lesions in active stage were enhanced by Gd-DTPA or no enhancement, the enhanced size of plaque was smaller than the extent showing hyperintense on T 2WI. The case of several onset showed various enhancement. Conclusion MS of spinal cord has characteristic feature on MRI, this can provide reliable proof for clinical diagnosis.

Objective To study on the value and safety of early endoscopic retrograde cholangiopan-creatography (ERCP)and endoscopic sphincterotomy (EST) in acute biliary pancreatitis. Methods Ninety-two patients with acute biliary pancreatitis underwent early ERCP (within 72 hours) and received endoscopic therapy (ERCP group). Another 40 patients with acute biliary pancreatitis were treated conservatively without ERCP (control group). The disappearance of abdominal pain, decrease of serum amylase level, the mean days and costs of hospitalization and complications were observed in all patients. Results In ERCP group, all patients were performed EST, stones in 72 choledocholithiasis patients had been removed with net-basket or air pocket. Ten cases of severe acute biliary pancreatitis received endoscopic pancreatic duct stents drainage. Ninety two cases of acute biliary pancreatitis received endoscopic nasal catheter bile drainage. The days of the disappearance of abdominal pain, the decrease of serum amylase levels, the cost of the hospitalization and the days of the hospitalization were significantly shorter in the early ERCP group than in the control group. The mortalities in ERCP and control group were 8. 3% and 33. 3% respectively. Conclusion Early ERCP endoscopic therapy is a safe procedure has the superiorities in lowering the mortality, hospital days and expense.

Objective To evaluate the effectiveness of autologous platelet-rich gel (APG)in the repair of diabetic foot ulcers.Methods This study was a single-center,prospective,randomized controlled trial.A total of 60 patients with diabetic foot ulcers (Wagner grade 2 - 3 )were randomly divided into autologous APG group (treatment group)and recombinant bovine basic fibroblast growth factor gel group (control group).After 8 weeks, we compared wound healing rate and wound healing time at five levels (overall ulcer,superficial ulcer,sinus ulcer, Wagner 2 and Wagner 3)in the two groups.Results In APG treatment group and control group,the healing rate of overall sample ulcer (93.33% vs .63.33%,P =0.005),sinus ulcer (84.62% vs .36.36%,P =0.033),Wagner 3 (81.82% vs .30%,P =0.030)differed significantly,but did not significantly differ in superficial ulcer (100%vs .78.95%,P =0.106)or Wagner 2 (100% vs .80%,P =0.106).Ulcer healing time was 31 d vs .41.5 d,23 d vs .32 d,32 d vs .56 d,25 d vs .32 d,38 d vs .56 d,with significant difference between the two groups (P <0.05). Conclusion Autologous platelet-rich gel can effectively increase the curative rate of diabetic foot and shorten healing time.

Iodine is one of the essential trace elements for human body. Its main physiological function is to synthesize thyroid hormones, which are involved in the development and metabolism of the body. Although China has achieved the goal of eliminating iodine deficiency disorders (IDD), people ignore the general iodine deficiency in the environment, and they are worried about excessive iodine intake and reduce the consumption of iodized salt. This may lead to a comeback of IDD, especially in high-risk groups such as pregnant women, breastfeeding women, adolescents and children. Russia is a geographically iodine-deficient country either. Russia was assessed by Iodine Global Network (IGN) as the third most severely iodine-deficiency country in 2019, and the actual average iodine consumption of Russian residents was less than 1/3 of the minimum standard set by the World Health Organization (WHO). Compared with Russia, China has basically eliminated IDD due to implementation of iodized salt and application of real-time and effective monitoring systems. Therefore, this paper compares the monitoring and prevention strategies of IDD between China and Russia, in order to learn from each other and improve the citizens' awareness of prevention and control of IDD in China and Russia, and to achieve correct, scientific and precise iodine supplementation.
