Children aerophagia is a relatively rare functional gastrointestinal disease.Its main clinical manifestations are swallowing air,chronic bloating,belching and increased anal exhaust.Since lack of understanding of children aerophagia in pediatricians,it can be very easily missed or misdiagnosed in clinic.Understanding of the research status about children aerophagia means to pediatric clinical guidance.This review summarizes the causes,clinical manifestation,diagnosis and treatment of children aerophagia.

To investigate the effects of the free radical, 1,1-Diphenyl-2-picylhydrazyl, on cochlear blood flow, 20 guinea pigs were divided into 3 groups at random, 6 for control group, 6 for 1 mmol/L group and 8 for 0.1 mmol/L group. 2 microliters vehicle or drugs were dropped into round window membrane (RWM). Cochlear microcirculation was monitored by laser Doppler flowmeter (LDF), and mean arterial blood flow (MABP), which was transferred by pressure conductor sensor and preamplifier, was simultaneously recorded on the computer. Our results showed that MABP was stable throughout the experiment. Cochlear blood flow (CBF) increased by 10.32% (P < 0.05) in 1 mmol/L group, and decreased by 4.89% in 0.1 mmol/L group (P < 0.05). In control group cochlear microcirculation showed no significant changes. It is concluded that DPPH exerted effects on cochlear microcirculation.

Objective To analyse the key influential factors for research performance of medical colleges and provide evidenes for further research management. Methods A questionnaire suvery was carried out in Shanghai Jiaotong University School of Medicine.Through stratified cluster sampling,those who assumed all ranks of projects from 2001 to 2006 in Basic Medical College and some affiliated hospitals were investigated.Two hundred and sixty questionnaires were sent out and 211(81.2%) were reclaimed.Delphi and comprehensive analysis were used to measure the research performance,and multi-Logistic regression was employed to analyze the influential factors for research performance.Results The key influential factors for research performance included research team,research investment,age of researchers,international exchanges and communications,and extra working hours for research.Conclusion To improve the research performance of medical colleges,it is most important to strengthen research team development,expand research investment,promote acedemic exchanges and communications,and initiate dedicated spirit for research work.

Objective To compare the treatment effects and side events between chemoradiotherapy and radiotherapy alone for patients with primary cervical cancer.Methods Totally 197 patients with primary cervical cancer in our hospital from 2000 to 2006 were studied.They were divided into two groups: radiotherapy alone(RT)or cisplatin-based chemoradiotherapy(CRT).Group of RT included 100 patients who received external irradiation by ~(60)Co and intracavitary irradiation by ~(192)Ir.Group of CRT included 97 patients who received cisplatin-based chemoradiotherapy.The RT regimen was the same as group RT.Results The local control(CR+PR)in two groups had no statistic difference(P=0.500).The total 5 year survival rate in the two groups were 82% and 79%,with no significant difference(P=0.177);however,there was a significant difference for stage Ⅲ squamous cell carcinoma of the cervix,the 5 year survival rate being 56% and 84%,respectively(P

Trust financing is a new financial instrument on the market at present.Combined with the new health reform and macroeconomic background,the paper firstly summarized the basic theory of public hospitals'trust financing,discussed the feasibility of public hospitals'trust financing,then put forward some policy suggestions for how to perfect trust financing for public hospitals from improving external environment,increasing government support,optimizing of hospital risk mitigation mechanism and income security mechanism,regulating hospital project information disclosure,training professional talents on the basis of analysis of three models of public hospitals' trust financing.

Objective:To investigate the expression of NKG2D in peripheral blood of patients with ovarian benign or malignant tumors, and the expression of the human MHC class Ⅰ chain-related gene A(MICA) on the correspondent tumor tissues. To analyze and discuss the function of NKG2D in anti-ovarian cancer mechanism and its relation with immune escaping of cancer.Methods:Flow cytometry analysis was used to detect NKG2D in the peripheral blood of 42 ovarian carcinoma patients, 23 ovarian tumor patients and 20 health persons. The expressions of MICA in part of the correspondent tissues were examined by means of reverse transcription-polymerase chain reaction (RT-PCR).Results:The expression of NKG2D were (94 23?6 02)%?(98 70?0 98)%?(98 61?1 59)% respectively, compared with the other two groups, the NKG2D expression in malignant group was significantly low; The rate of MICA mRNA expression in ovarian carcinomas was significantly higher than that in benign and normal tissues. No evident relation was found between the expression of MICA mRNA and the clinical factors.Conclusion:The activity of NK cell and the anti-cancer cellular immunity level reduce in patients with ovarian cancer; The decrease of the receptor NKG2D is a reason for the descend of the activity of NK cells; MICA mRNA expression is relative to malignant transformation; the immune-escape of ovarian cancer probably is relative to the down-regulation of NKG2D and the up-regulation of its ligand MICA.

Objective To evaluate the safety, efficacy and morbidity of transurethral electrovaporization of superficial bladder tumor (TVBt). Methods TVBt was performed in seventy-three pat iens (mean age 66 years) with superficial bladder carcinoma,twelve of them trans urethral electrovaporization of the prostate (TVP) was carried out simultaneousl y for concomitant BPH. Results The tumor was resected in one-stage for 72 cases,in two-stage for multiple tumors in one patient. The mean operative time was 29 minutes in simple TVBt group, and 78 minutes in the group performing both TVBt and TVP. Intraoperative bladde r perforation occurred in 1 case, No patient need blood transfusion for bleeding . The mean duration of an indwelling urethral catheter was 46h. All patients wer e followed up for twenty-four months, and the recurrence rate was 21% within t wo years after the operation. Conclusions TVBt is a simp le, effective and safe surgery for the treatment of superficial bladder cancer.

To investigate the current condition of cognitive misunderstandings of English learning among students with traditional Chinese medicine majors, in order to put forward strategies for English learning in TCM universities.The investigation was carried out by the method of questionnaires among the students with TCM majors. Another investigation was carried out by interviews with TCM students, English teachers and experts, TCM teachers and experts. Cognitive misunderstandings of English learning among students with TCM majors occurred, such as low participation of English extracurricular learning, wrong learning motivation, weak awareness of self-learning and international exchange and communication. There were 3 ways for solving cognitive misunderstandings, including that students could improve the correct learning attitude and self-learning awareness and practice, that English and TCM teachers and experts could give students some advice of career development and TCM internationalization, and that TCM universities could reinforce English and bilingual teacher team construction, improve educational environment.

Objective To Investigate the important perennial inhaled allergens for children with allergic asthma in Daqing.Method Analyzing the data from 134 patients between 4 and 14 years of age with asthma who have a positive skin test to perennial aeroallergen and also have been carried out Allergen-specific immunotherapy in the last four years.Results The important perennial inhaled allergens for children with allergic asthma in Daqing were house dust,dust mites,polyvalent molds Ⅰ(PMⅠ),animal epithelium and polyvalent molds Ⅱ(PMⅡ).Among them the most important allergens were house dust and dust mites.Conclusion It will have practical significance to prevent and treatment children's asthma by taking measures for these allergens.
