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.

The roles of voltage-dependent K(+) channels during activation and damage in alveolar macrophages (AMs) exposed to different silica particles were examined. Rat AMs were collected by means of bronchoalveolar lavage, and were adjusted to 5x10(5)/mL. After AMs were exposed to different concentrations (0, 25, 50, 100, 200 mug/mL) of quartz particles and 100 mug/mL amorphous silica particles for 24 h, the voltage-depended K(+) current in AMs was measured by using patch clamp technique. Meanwhile the leakage of lactate dehydrogenase (LDH) and the viability of AMs were detected respectively. Patch clamp studies demonstrated that AMs possessed outward delayed and inward rectifying K(+) current. Exposure to quartz particles increased the outward delayed K(+) current but it had no effect on inward rectifier K(+) current in AMs. Neither of the two K(+) channels in AMs was affected by amorphous silica particles. Cytotoxicity test showed that both silica particles could damage AM membrane and result in significant leakage of LDH (P<0.05). MTT studies, however, showed that only quartz particles reduced viability of AMs (P<0.05). It is concluded that quartz particles can activate the outward delayed K(+) channel in AMs, which may act as an activating signal in AMs to initiate an inflammatory response during damage and necrosis in AMs induced by exposure to quartz particle. K(+) channels do not contribute to the membrane damage of AMs.

Objective To investigate the causes and managements of dys-seal syndrome (DSS) developed after esophageal stent placement. Methods From June 2001 to June 2008, esophageal stenting was performed in 98 consecutive patients with malignant esophageal obstruction. A total of 99 metallic stents were used. Of 98 patients. gastroesophageal anastomosis stricture was seen in 19, preoperative radiotherapy history in 26 and tracheoesophageal fistula in 34. Results DSS occurred in 7 patients, with an occurrence rate of 7.14% ,which was significant higher than that in patients with preoperative radiotherapy history and in patients showing marked dilated esophagus proximal to the obstructed site (X~2=0.017, 0.005, P=0.036, 0.013, respectively). After treatment, such as fasting, IPN or nasogastric feeding,only 1 case retumed to semi-liquid diet. Among the rest 6 cases of DSS, an additional stent was employed in one (but in vain), nasogastric feeding tube was used in 2, and removal of the stent under endoscopic guidance was carried out in 3. Conclusion DSS is one of the complications developed after esophageal stent placement, its prognosis is rather poor. Removal of the inserted stent may be the optimal treatment. The prevention of DSS includes proper pre-operation evaluation, selection of suitable stent, enhancement of perioperative nutritional support, etc.
