Objective By analyzing the epidemiological characteristics and trends of brucellosis in Ji'nan City,to provide a scientific basis for further prevention and control of the disease.Methods Serum samples of suspected brucellosis patients were collected from every county (city,district) of Ji'nan City from 2008 to 2014,and these samples were screened by Rose-bengal plate agglutination test (RBPT).Then positive samples were confirmed by Standard tube agglutination test (SAT),and experimental data and results were analyzed by statistics.Results Totally 2713 serum samples of suspected brucellosis patients were tested,and 200 were positive by SAT.Temporal distribution:the serum antibody positive specimens were detected each month throughout the year,and the results showed clear seasonal prevalence by concentrating from March to September (82.07％,151/184).Population distribution:the serum antibody positive rate of males was higher than that of females,the ratio was 2.08:1.00,and the cases were found among 15 to 75 years old,while concentrated from 30 to 65 (67.00％,134/200).Spatial distribution:except Huaiyin District,positive samples were detected in all other 10 counties (cities,districts) of Ji'nan City,most of them (92.5％,185/200) in Shanghe,Zhangqiu,Changqing,Shizhong and Licheng counties (cities,districts).Conclusions Brucellosis epidemic in Ji'nan is serious,and cases have occurred mostly in spring,summer and autumn.It is recommended that health propaganda and education should be strengthened in order to enhance selfprotection awareness of the exposed population,and then improve the physical examination for early discovery,early reporting and early treatment.At the same time,it is important to cooperate with the Department of Livestock to prevent and control brucellosis.

The paper introduced the background and concepts of municipal trusteeship of district-launched medical institutions, with the trusteeship of women and children′s hospital of Shunyi district as an example.In addition to the main approaches and contributions in improving hospital management, delivery of quality medical resources to primary care, and capacity building, the authors called for the support for standardized healthcare, respect for original hospital culture, and sustained government support to the hospital in question among other points, for reference of further public hospital reform.

[Objective]To analyze the advantages of transparent cap assisted endoscopy in the diagnosis and treatment of duode-nal diseases.[Methods]From September 2014 to December 2015,62 cases with suspicious duodenal diseases in the endoscopy cen-ter of our hospital randomly divided into transparent cap group(n=31)and routine group(n=31)according to the time sequence. The visual field resolution,success rate of image capture and operating time were compared in 2 groups.[Results]Thirty cases in transparent cap group had clear visual field definition ,which was obviously higher than 9 cases in conventional group (96.8% vs 29%,P < 0.001). Twenty-three cases in transparent cap group and 8 cases in routine group were successfully captured(90.3% vs 25.8%,P < 0.001). The average operating time of the transparent cap group was significantly shorter than that of the conventional group(150+58 vs 95+36 seconds,P=0.004).[Conclusion]Transparent cap endoscope examination is more effective in the treat-ment of duodenal diseases,and the image capture is higher and the operation time is shorter.

Objective To evaluate the feasibility of transparent cap-fitted endoscopy in improving diagnostic yield of Barrett's esophagus(BE).Methods A total of 168 patients with endoscopieally suspected BE were randomly divided into cap group(n=60)and control group(n=108).A transparent cap-fitted endoscopy Was applied in cap group to take biopsy,while a routine one was used in control group,and 2 biopsies from suspected lesions were collected in each patient.BE was diagnosed in the presence of columnar epithelium and the diagnostic rate was compared between 2 groups.Results The diagnostic rates of BE were 83.3%(50/60)and 69.4%(75/108)in cap and control group,respectively(P＜0.05).Conclusion The lesions at cardia Call be exposed clearly with capped endoscopy,which facilitates localized biopsy and BE diagnosis.

A method of complete acid hydrolysis combined with high performance anion exchange chromatography and pulsed amperometric detection was developed for the monosaccharide composition analysis of arabinoxylan from the seeds of Plantago asiatica L. The parameters including hydrolysis methods, acid types, acid concentration, hydrolysis temperature, hydrolysis time and placement time, which would affect the hydrolysis process, were optimized. The results showed that it would have a better hydrolysis effect for polysaccharide from the seeds of Plantago asiatica L. with 2 mol/L H2 SO4 in an atmospheric oil bath at 120℃for 2 hours. However, the placement time for diluted solution of the hydrolyzed polysaccharide should be less than 6 hours. The polysaccharide was mainly composed of Arabinose (8. 89%) and Xylose (41. 52%) and Galacturonic acid (0. 73%). Glcuronic acid (3. 44%) was detected simultaneously, and there were also trace amounts of Galatose and Glucose. The results were reproducible. Other arabinoxylans from Panicummiliaceum L. shell, Avena sativa L. bran and Hordeum vulgare L. were taken for monosaccharide compositions analysis under the optimal hydrolysis conditions and the analysis results were good. This study would provide a good reference for monosaccharides composition analysis of arabinoxylans from various sources.

The acupoint sensitization theory,a breakthrough in acupuncture and moxibustion over the past two decades,has greatly enhanced the understanding of meridians and acupoints while increasing the effectiveness of clinical diagnosis and treatment in acupuncture and moxibustion practices.The number of studies on surface sensitization site detection for different diseases is increasing.However,systematic sorting and a summary of the detection mode of surface sensitization points are lacking.Therefore,this study categorizes the method of surface sensitization point detection into two modes:pan-scanning and focused scanning.The classification is based on the characteristics of the openness of the research purpose,the precision of the target range,and the degree of variation during detection.The two modes have considerable differences in the exploration efficiency and the presentation of result.The pan-scanning mode can be further subdivided into holistic and localized pan-scanning modes,whereas the focused-scanning mode can be subdivided into fixed-and variable-focused scanning modes.This study analyzes the application scenarios,characteristics,advantages,and limitations of each detection mode and presents opinions on mode selection,mode innovation,and future development directions.This study aims to provide valuable insights and guidance for the follow-up research on surface sensitization site detection of various diseases.

Objective:Explore the " project-talent-base" combining international science and technology cooperation management model and mechanism through summarizing the practical experience of a tertiary pediatric hospital in Beijing in recent years, to provide reference for strengthening the hospital′s international science and technology cooperation.Methods:Main problems existing in the management of international science and technology cooperation in domestic medical institutions are analyzed, and management methods of international science and technology cooperation adopted by the hospital are classified through policy sorting, literature research, summarization and classification.Results:The hospital has established an efficient and high-quality international science and technology cooperation management model mainly through four aspects: improving the international cooperation management system, enriching international cooperation and exchange projects, building different types of international science and technology cooperation platforms, and strengthening personnel training.Conclusions:Under the background of the globalization of science and technology and the accelerating pace of scientific research in China, improving the hospital′s international science and technology cooperation management model will effectively promote the introduction of international advanced technologies and concepts, and enhance the overall science and technology innovation capabilities and discipline construction.
