BACKGROUND: Malnutrition and overnutrition are the two problems during growth and development of high-school students.OBJECTIVE: To understand the situation and relevant factors of malnutrition and overnutrition of high-school students.DESIGN: Transverse investigation was designed.SETTING: Health Supervision Institute of Chongqing Health Bureau; Department of Nutrition & Food Hygiene, Chongqing University of Medical Sciences; the Eighth Middle School of ChongqingPARTICIPANTS: Totally 896 students in 15 classes were collected from one full-time middle school in Shapingba district in Chongqing by cluster sampling method from March to May 2004. The students were excluded if they suffered from hereditary metabolic disease and secondary pathological malnutrition or obesity due to trauma or other diseases. All of participants were in the known in the investigation. Of those, 826 students filled up the questionnaire in detail (the effective rate was 92.19%), in which, 414 students were male and 412 students female, aged varied from 13 to 18 years.METHODS: The students chose were in the investigation with questionnaire and the contents of it included basic physical situation, state of sickness, situation of parents, dietary behavior, nutritional knowledge, dietary habits, etc. The students filled up the questionnaire by them own and handed over on the spot. The evaluation of student nutrition state adopted the heights and body masses in recent physical examination scale, in reference to the criteria in "height and body mass of Chinese students aged from 7 to 22 years". The standard body mass was 80% of body masses of people with same height, based on which, the standard body mass was 100%, that less than the standard by 90% was taken as malnutrition and more than it by 120% was taken as obesity. Non-conditional logistic stepwise regression was used to analyze the data so as to probe into the factors of malnutrition and obesity in middle-school students.MAIN OUTCOME MEASURES: [1] Morbidity of malnutrition and obesity in middle-school students. [2] Factors of malnutrition and obesity in middle-school students.RESULTS: Totally 826 students entered result analysis. [1] Morbidity of malnutrition and obesity: it was 9.44% and 24.21% respectively, in which,the morbidity of malnutrition.for female was higher than male [4.84%,14.08% (x2=15.1036, P ＜ 0.05)] and the morbidity of obesity in male was higher than female [30.09%, 18.2% (x2=10.5737, P ＜ 0.05)]. [2] Factors of malnutrition and obesity: significant correlation was present between malnutrition and 5 factors, named sex, indulgence in or being choosy food,sleeping time, breakfast and animal internal organs (P ＜ 0.05-0.01). Significant correlation was present between obesity and 5 factors, named sex,body mass index of father, eating velocity, midnight snack and indulgence in or being choosy food (P ＜ 0.05-0.01).CONCLUSION: It is discovered in the investigation that the morbidity of malnutrition and obesity in middle-school students are very high and that is all closely related to sex and indulgence in or being choosy food. In order to correct malnutrition and obesity in middle-school students, it is necessary to provide correct nutritional knowledge and help them arranging diet rationally and establishing healthy life pattern.

Objective To investigate parenteral nutrition and enteral nutrition therapy for esophageal cancer patients nutritional status improvement.Methods Totally 63 patients with esophageal cancer were chosen,preoperative Nutritional Risk Screening 2002 (NRS2002) nutritional screening through joint after parenteral nutrition and enteral nutrition therapy.Patients with intestinal tolerability and complications after surgery on days 1 and 7 days nutrition indicators were observed,including total serum protein,albumin,prealbumin,hemoglobin,and lymphocyte count.Results Preoperative risk malnutrition occurred in 39 patients.Compared to patients on day 1 after the first 7 days,serum levels had no significant difference in total protein.Albumin,prealbumin,hemoglobin,and lymphocyte counts were significantly different statistical significance (P ＜ 0.05).Conclusions NRS2002 for nutritional screening patients at risk of malnutrition can be determined,and the combined parenteral and enteral nutrition therapies can improve nutritional status of patients with esophageal cancer.

Objective To learn the applications and patient experience of mobile payment technology as used in the hospital outpatient service.Methods 342 outpatients using mobile technology (APP)were chosen from the hospital information system for survey,and 300 outpatients registering in the conventional process were chosen as a control.Data of the doctor-seeing experiences of the two groups were analyzed statistically.Results Waiting queue reminder function is found with the highest patient usage among the three officially launched APPs,accounting for 83.6%.The appointment and cellphone payment functions exert the greatest impact on patient experience,boasting a patient satisfaction of 90%. All these functions can save totally one hour for an outpatient.Conclusions The mobile payment technology can significantly reduce outpatient waiting time,and improve outpatient experiences.Such technology therefore needs more promotions and connection with medical insurance system for the sake of outpatients.

Objective Based on dual channel melting curve analysis-based assay,we developed a method to rapidly detect the drug-resistant mutations in Mycobacterium tuberculosis through real-time PCR.Methods According to the common first-line drug-resistant mutations of Mycobacterium tuberculosis,we designed six dual-labeled fluorescence probes to rapidly detect the drug-resistant mutations through realtime PCR melting curve after amplifications of drug-resistant related gene region of DNA.The targets include rpoB 81 bp core region,katG315,inhA promoter,ahpC promoter and embB306.To validate the sensitivity and specificity of our method,we performed real-time PCR assays to detect drug-resistant mutations in 76 clinical MDR-TB samples,which were collected by Shanghai CDC in 2008.Results In the validation,this method successfully detected drug-resistant mutations in all 76 clinical MDR-TB samples.The △Tm of mutations were from 1.8 to 14.4 ℃.Comparing with the sequencing data,all mutations covered by the six probes were detected with 100％ sensitivity and 100％ specificity (rpoB,80/80; inhA,7/7 ; katG315,59/ 59;ahpC,8/8;embB306,27/27).This method can successfully detect drug-resistant mutations from 100 copies/μl DNA samples.Conclusions A widely applicable real-time PCR assay to detect first line drug-resistant mutations of Mycobacterium tuberculosis has benn developed.This method has proven to have the advantages of high sensitivity,specificity and low risk of contamination.It can be used in rapid diagnosis of clinical drug-resistant tuberculosis and the evaluation of laboratory drug sensitivity test.

Objective To investigate the expression level of peripheral blood mononuclear cell(PBMC)human leucocyte anti-gen G(HLA-G)in patients with hepatocellular carcinoma(HCC).Methods The HLA-G mRNA in PBMC from 44 patients with HCC,21 patients with liver cirrhosis and 40 healthy subjects were measured by reverse transcription real time fluores-cent relative quantitative PCR.Results HLA-G mRNA expression level were 1.71±0.39,1.05±0.38 and 1.01±0.47 in HCC group,liver cirrhosis group and healthy control group respectively.HCC group was higher than the other two groups, the difference was statistically significant (F=33.657,P<0.001).The survival rate of HCC patients in HLA-G mRNA high-expression group was lower than HLA-G mRNA low-expression group,the difference was statistically significant (χ2=5.972,P=0.015).Conclusion PBMC HLA-G mRNA in HCC was closely correlated with tumorigenesis.It can proviede a novel diagnosis and research tool for HCC.
