Objective: To understand and analyze the current situation and secular trends for prevalence of malnutrition among Chinese children and adolescents aged 7-18 years from 2005 to 2014, and to provide important scientific basis for students' nutrition improvement.Methods: All the subjects aged 7-18 years in both sexes were sampled from 2005, 2010 and 2014 Chinese National Surveys on Students Constitution and Health.According to the new students' health standard of Screening Standard for Malnutrition of school-age children and adolescents(WS/T456-2014) in 2014 of China, the nutritional status of children in 31 provinces (autonomous regions and municipalities, excluding Hong Kong, Macao and Taiwan province) were analyzed and compared in different ages, genders, regions and provinces from 2005 to 2014.The Tibetan students was used with the data of Tibetan minority and all the other students from 30 provinces (autonomous regions, municipalities) were Han minority.Results: The prevalence of malnutrition of children and adolescents of Han minority aged 7-18 years in 2014 was 10.0%.The prevalence of malnutrition components, including stunting, mild wasting and moderate severe wasting, were 0.8%, 3.7%, and 5.5%.Compared with 2005 and 2010, the prevalence of malnutrition of Han children and adolescents in 2014 had declined with 5.0 and 2.6 percentage points, respectively, and its components had declined with 1.0, 1.8, 2.2 and 0.4, 1.1, 1.2 percentage points, respectively.The prevalence of malnutrition of 2014 in boys was higher than in girls (11.1% vs.8.9%), the rural was higher than the urban (11.0% vs.9.1%) and the west (11.7%) was higher than the east (9.0%) and the middle (9.2%).Mild wasting of Chinese children and adolescents aged 7-18 years was the main component in malnutrition and the stunting in the Han and Tibetan children and adolescents only accounted for 8.0% and 7.5%, respectively.Compared with 2005 and 2010, the prevalence of malnutrition for Chinese children and adolescents aged 7-18 years in 2014 had declined with various extents constantly, and there was a statistically significant difference among three surveys (P<0.05).Provinces (autonomous regions, municipalities) with high prevalence of malnutrition mainly concentrated in the southwest of China from 2005 to 2014.Compared with 2005 and 2010, the prevalence of malnutrition declined in 31 provinces (autonomous regions, municipalities) of China in 2014.The number of provinces (autonomous regions, municipalities) with high prevalence of malnutrition decreased constantly and increased for the number of province (autonomous regions, municipalities) with low prevalence.Conclusion: The prevalence of malnutrition among Chinese children and adolescents aged 7-18 years had declined from 2005 to 2014, but the total prevalence of malnutrition was still high.Mild wasting was the main component in malnutrition and the prevalence of stunting was low.Provinces (autonomous regions, municipalities) with high prevalence of malnutrition mainly concentrated in the southwest of China.

Objectives To compare the migrating motor complex (MMC) in irritable bowel syndrome (IBS) patients with that in healthy controls. To explore whether discrete clustered contractions (DCC) are connected with abdominal pain in IBS patients. To improve the method of measuring gastroenteric motility (esp. jejunum). Methods By using 16-channel water-perfused catheter and manometry instruments, MMC in 16 cases of IBS with constipation (IBS-C), 18 cases of IBS with diarrhea (IBS-D) and 18 cases of healthy controls were monitored. Results The MMC durations of IBS-C and IBS-D patients were (127.5±25.5) min and (74.5±18.7) min, respectively. Comparision with those in the control group [(87.5±24.2) min]showed significant differences (P<0. 001). The contraction amplitudes of stage Ⅲ in different sites of IBS-C patients decreased significantly as compared with those in the controls [jejunum, (39.8±11.7) mm Hg vs. (61.1±14.1) mm Hg,P<0.001,1 mm Hg=0.133 kPa]. The propagation velocities of stage Ⅲ in different sites of IBS-C patients also decreased significantly as compared with those in the controls [jejunum, (1.8±0.9) cm/min vs. (2.6±0.8) cm/min,P<0.01].The contraction amplitudes of stage Ⅲ in different sites of IBS-D patients increased significantly as compared with those in the controls [jejunum, (69.7±20.5) mm Hg vs. (61.1±14.1) mm Hg, P<0.01]. The propagation velocities of stage Ⅲ in different sites of IBS-D patients also increased significantly as compared with those in the controls [jejunum, (4.1±2.5) cm/min vs. (2.6±0.8) cm/min, P < 0. 01]. DCC incidences of IBS-C and IBS-D were 87.5% and 88. 8%, respectively. Comperision with those in the normal group (83.3%) did not show significant difference (P>0.05). The prevalences of abnormal stage Ⅲ contractions (include disturbances and interferences of stage Ⅲ contractions) in IBS-C and IBS-D patients were 68.8% and 66. 7%, respectively; there were no significant differences between the two groups (P > 0. 05). However abnormal stage Ⅲ contractions did not exist in healthy controls. Conclusions (1) The MMC of IBS-C and IBS-D patients are changed, as compared with that in healthy people; this implies that small intestinal motility dysfunction is one of the pathogenetic factors of IBS. The abnormal stage Ⅲ contractions in jejunum may be a predominant change in IBS gastroenteric motility. (2) No apparent connection is found between DCC and pain in IBS. (3) By using 16-channel water-perfused catheter, we first carried out the method of monitoring jejunum contractions in China. Parameters of MMC in Chinese healthy people were investigated, esp. those of jejunum.

Objective To investigate the expression of CD40 and intercellular adhesion molecule-1 (ICAM-1) treated with lipopolysaccharide (LPS) in rat peritoneal mesothelial cells(RPMC) and the role of NF-κB signal transduction pathway. Methods RPMCs were harvested from Sprague-Dawley rat peritoneal cavity and maintained under defined in vitro conditions. The cells were exposed respectively to different concentrations of LPS for 12 h or treated with LPS (5 μg/ml) for different time points. To observe the effect of LPS on the expression of CD40 and ICAM-1, the RPMCs were treated with LPS (5 μg/ml) for different time points. To observe the effect of LPS on the expression of NF-κB and p-NF-κB protein, the RPMCs were treated by LPS or pretreated with BAY11-7085 (5 μmol/L or 1 μmol/L ) for 3 h, then treated with LPS for another 3 h, respectively. Expression of CD40 and ICAM-1 mRNA was examined by RT-PCR. Expression of NF-κB and p-NF-κB protein was detected by Western blot. Results Compared with medium control group, stimulation of RPMCs with 1 μg/ml and 5 μg/ml of LPS resulted in a significant increase in the expression of CD40 and ICAM-1 mRNA(P<0.05). 10 μg/ml of LPS had strongest effect on CD40 and ICAM-1 expression compared with that of 1 μg/ml and 5 μg/ml of LPS. Treatment with 5 μg/ml of LPS resulted in time-dependent increase in the gene level of CD40 and ICAM-1, with the peak at 3 h. However, after that time point, the gene level of them was gradually attenuated. Following treatment with LPS (5 μg/ml), the level of p-NF-κB began to increase at 15 min, gradually reached the peak at 1 h, and then decreased. But the level of p-NF-κB at 2 h was still significantly higher than that of medium control. 5 μmol/L of BAY11-7085 decreased significantly the up-regulation of CD40 and ICAM-1 induced by LPS. Conclusion LPS enhanced the expression of CD40 and ICAM-1 on RPMCs in a concentration-dependent and a time-dependent manner. LPS induced expression of CD40 and ICAM-1 depend on the NF-κB signal transduction pathway.

Objective To assess the efficacy and safety of premedicaton with pronase before upper gastrointestinal endoscopy (UGI).Methods A total of 440 outpatients from 5 centers were randomly assigned to receive endoscopy with one of three premedications as follows:dimethylpolysiloxane (DMPS) and pronase (group A,n =170) ; DMPS and sodium bicarbonate (group B,n =170) ; DMPS,pronase and sodium bicarbonate (group C,n =100).Six endoscopists,who were unaware of the premedication types,calculated the visibility scores (range,1 to 4) of the antrum,gastric body,and fundus.The sum of the scores from the three locations was defined as the total visibility score.Results With regards to routine white light endoscopy,the total visibility score of group C was significantly higher than that of group A (P =0.0001),and the score of group A was significantly higher than that of group B (P =0.0019).Concerning chromoendoscopy,the total visibility score of group C was significantly higher than that of group A (P =0.0054),and the score of group A was also significantly higher than that of group B (P ＜ 0.0001).Conclusion Combined application of pronase,dimethylpolysiloxane,and sodium bicarbonate before UGI endoscopy significantly improves endoscopic visualization.

ObjectiveTo investigate the effects of Taijiquan training on bone density and balance function of post-menopause women. Methods59 volunteers of post-menopausal women were divided into Taijiquan group and control group. Bone density was examined with DPX-L. The balance function were recorded with win-pop balance monitor and star diagram. ResultsBone density in lumbar vertebra, left collum femoris and left Ward's septa were higher in the Taijiquan group than in the control group. The lengths of center excursive loci reduced in Taijiquan group. The distances that the foot could touch were longer at Posterolateral, posteromedial, posterior, lateral(back) directions in the Taijiquan group than in the control group. ConclusionTaijiquan training can improve the bone density and balance function in post-menopause women.

OBJECTIVE: To explore the injury mechanism of the human knee in a traffic accident by establishing a 3D finite element (FE) model. METHODS: The FE model, composed of femur, tibia, fibula, patella, meniscus, knee ligaments and surrounding soft tissues, was reconstructed by CT scanning data from a male volunteer. Validation was performed by the lateral impact simulation, and the stress and strain results were obtained to be compared with those previously reported for injury prediction. RESULTS: The results derived from the FE model were found to be similar with those previously reported, most of the ligaments and meniscus wounded at 40 m/s collision, which was readily observed. CONCLUSION The simulation results generated by FE model can be effectively used for the injury mechanism analysis of initial contact.

In this study, the rat type 2 diabetes mellitus (T2DM) model was established through tail vein injection with low dose of streptozotocin (STZ) and high fat diet for 8 weeks, and then treated with Jiaotai Pill. The oral glucose tolerance test (OGTT), fasting serum insulin (FINS), free fatty acid(FFA) levels and blood lipid were assayed. HOMA-IR was calculated. Pancreatic pathology was performed. And pancreatic triglyceride (TG) content was examined by the lipid extraction method. Pancreatic islet cell apoptosis were detected by terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling (TUNEL). According to the results, the model group showed abnormal OGTT, increased FINS, HOMA-IR, FFA, lipid disorder, obvious fat accumulation and significantly increased TG content in pancreatic tissues, and enhanced pancreatic islet cell apoptosis. Compared with the model group, the Jiaotai Pill group displayed improved OGTT, reduced FINS, HOMA-IR, FFA, recovered lipid disorder, decreased fat accumulation and significantly declined TG content in pancreatic tissues, and lowered pancreatic islet cell apoptosis. In summary, Jiaotai pill could effectively treat type 2 diabetes in rats. Its mechanism may be related to the reduction in pancreatic fat accumulation and islet cell apoptosis.
