OBJECTIVEA study was conducted to evaluate the clinical application of sialendoscopy combined with conven tional laparoscopy in a 30 degree angle in depth salivary calculus of submandibular glands.

METHODSA total of seventeen patients were presented with repeated swelling in the unilateral submandibular area from June 2013 to August 2015. All patients underwent CT examinations of the mandible and salivary gland function imaging preoperatively. Sialoendoscopy and conventional endoscopy were applied to do intraoral lithotomy. Among the study group, thirteen cases were males and four cases were females. A total of twelve were left cases and five were right cases. Results Seventeen patients had deep positive calculus in the submandibular glands under CT. Photo technetium function was basically normal, whereas secretion of ipsilateral decreased significantly in salivary function tests. Double endoscope assisted surgeries were performed successfully through the mouth to remove the stones. The operation time was (42+21) min. There were no obvious complications in perioperative periods.

CONCLUSIONIntraoral lithotomy assisted by sialoendoscopy and conventional laparoscopy for deep stones in the submandibular glands is a new technique. This technique will possibly lead to complete avoidance of gland resection because of early deep sialolithiasis.

Objective Through the English newspaper reading activities to create the information transmission platform based on the medium of English,so as to improve the students' ability of receiving,understanding,conversion,processing,and output information.Methods Two natural classes of seven-year program students of Grade 2011 with no difference in Englishproficiencywere selected at randomas control group(30) and the experimental group(30).And reform on reading course has been performed in the experimental class by incorporating English newspaper reading into traditional teaching routine,while the control class maintain the traditional teaching routine.After the teaching,through CET 4 test scores to evaluate the teaching effect.Independent t-test was conducted on the performances of CET 4 between the experimental class and controlled class with the level of test α=0.05.Results The control group was higher than the experimental group inthe total scoreof CET 4 and the performance oflistening and reading,and there was significant difference between the two groups(P of totalscore=0.000,P of listening score=0.002,P of reading score=0.001).But there was no statistically significant difference in writing subtests between the two groups(P=0.072).Conclusion By adopting English newspaper reading and broadcasting in class,students' overall ability of using English has been greatly enhanced,especially the listening comprehension and reading comprehension; however,there is no significant change in the development of students' writing ability due to the tasks designed.

Objective To assess the effectiveness of Exenatide on non‐alcoholic fatty liver disease(NAFLD) with diabetes mellitus by evaluating fatty liver index(FLI) variation .Methods One hundred and two NAFLD patients with type 2 diabetes melli‐tus were enrolled and divided into two groups .One group were treated with Exenatide and another with Oral antidiabetic agents . The data of BMI ,blood fat ,HbA1c ,ALT ,AST ,GGT ,FLI and so on were collected at enrollment and the end point of 24 weeks treatment .The effectiveness of Exenatide were analysed by Kolmogorov‐Smirnov and Pearson correlation coefficient (r) analysis . Results The indicators of metabolic disorder ,the parameters of liver biochemistry and fatty liver disease (FLI) were significantly improved (P<0 .05) after 24 weeks treatment by Exenatide .While only BMI showed significant decrease after 24 weeks treatment with Oral antidiabetic agents(P<0 .05) .The rest of the parameters in oral antidiabetic agants group showed no significant differ‐ence (P>0 .05) .Conclusion Exenatide has a positive effect on non‐alcoholic fatty liver disease treatment who with type 2 diabetes mellitus ,especially for liver fat accumulation .

Cognitive function has become a hot spot in the field of epilepsy. However,the relationship between cognitive function and epilepsy has not been clearly demonstrated. Clinical trials have showed that epi-lepsy and epileptic relevant factors are both associated with cognitive function in children. Children with cogni-tive impairment are often caused by those two factors. This article focuses on cognitive function in children with epilepsy age below 6 years,and mainly reviews the characteristics of cognitive function in these children with epilepsy.

Objective To investigate the change of plasma L-threonine (L-Thr) ,D-threonine (D-Thr) ,L-alanine (L-Ala) and D-alanine (D-Ala) in the patients with primary hepatocellular carcinoma (HCC) by using the reversed-phase high-performance liquid chromatography (RP-HPLC) .Methods The o-phthaldialdehyde (OPA) and N-acetyl-L-cysteine (NAC) column with pre-column derivatization was adopted to perform the separation .The mobile phase was 20 mmol/L sodium dihydrogen phosphate solution and acetonitrile with a programmed gradient elution and the flow rate of 1 .0 mL/min .The excitation wavelength was set at 350 nm and the emission wavelength was set at 450 nm .Results The threonine and alanine enantiomers could be simultaneously determined by this method .The regression equation showed the good linear correlation The limits of detection (LOD) for L-Thr ,D-Thr ,L-Ala and D-Ala were 11 .4 pg/mL ,9 .77 pg/mL ,4 .11 pg/mL and 3 .50 pg/mL respectively .The recovery rate was 90 .22% -105 .7% .With-in-day and between-day RSD was 1 .04% -4 .11% .Conclusion The threonine and alanine enantiomers could be simultaneously de-termined by this method .The regression equation showed the good linear correlation The limits of detection (LOD) for L-Thr ,D-Thr ,L-Ala and D-Ala were 11 .4 pg/mL ,9 .77 pg/mL ,4 .11 pg/mL and 3 .50 pg/mL respectively .The recovery rate was 90 .22%-105 .7% .Within-day and between-day RSD was 1 .04% -4 .11% .

Clinical practice guidelines play an important role in practitioner and patient decisions regarding appropriate clinical health care and in health policy formation. In the guideline development process, inappropriate methodologies and development strategies significantly influence the quality of guidelines; therefore, research and evaluation of guidelines have great significance. The original Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was published in 2003 by a group of international guideline developers and researchers. AGREE has important significance for the quality guarantee and successful implementation of guidelines, and has extensively achieved endorsement since 2003. In 2009, The AGREE Collaboration has developed the AGREE II by refining the original AGREE instrument. At present, the AGREE II has already replaced the original AGREE instrument; however, related introduction regarding AGREE II has not been found in China. The authors of this article briefly introduce the AGREE II, and believe that it will add value to research and evaluation of the guidelines as a whole.

Objective To compare the efficacy of 10-day sequential therapy (including rabeprazole amoxillin clarithromycin tinidazole) and 7-day traditional trigeminy therapy (including rabeprazole amoxillin and clarithromycin) in patients with duodenobulbar ulcer and Hp infection. Methods Ninty-five patients with duodenobulbar ulcer and Hp infection were enrolled into the study and divided into two groups randomly:sequential therapy group and traditional trigeminy therapy group. Patients in the first group received 10-day sequential medications:rabeprazole 10 mg plus amoxillin 1 g for the first 5 days,followed by rabeprazole 10 mg plus clarithromycin 500 mg and tinidazole 500 mg for another 5 days;while in the second group patients received the standard 7-day traditional triple medications:rabeprazole 10 mg plus clarithromycin 500 mg and tinidazole 400 mg. All drugs were given twice daily. All patients received rabeprazole 10 mg daily following the two types of therapys for another four weeks. Hp statuses were assessed by rapid urease test and 14C urea breath test at baseline and 4 weeks after completion of the treatment. Ulcer cicatrization was assessed by gastroscope. Results The eradication rate of Hp infection was significantly higher in sequential group than triple group (89.5%vs. 70. 2%, P ＜ 0. 05 ), but we found no statistically significant difference in the comparison of the ulcer cicatrization rate between sequential group and triple group ( 87.5% vs. 82. 9%, P ＞ 0. 05 ). Conclusion Sequential therapy had a better Hp eradication effect than standard triple therapy, but the eradication rate was very close between the two therapys.
