BACKGROUND:Body mass is a critical factor affecting plantar pressure,and the systematic study on plantar pressure with different body mass has not been reported.OBJECTIVE:To measure the plantar pressure of normal people with different body weight,so as to provide reference for the application of plantar pressure.METHODS:Totally 80 healthy people with different body weight were enrolled,and the dynamic plantar pressure was measured by the Footscan 2 meter flat foot pressure distribution system (RSscan,Belgium).The participants were divided into four groups (n=20 per group) according to the classification criteria for prevention and control of overweight and obesity in Chinese adults,such as underweight,normal weight,overweight group,and obesity groups,and a comparative analysis was conducted.RESULTS AND CONCLUSION:(1) The peak pressure and impulse of each region of the foot were significantly increased with body mass index increasing (P ＜ 0.05).Compared with the normal weight people,the pressure of the part foot area of the overweight subjects and each part foot area of the obese subjects were significantly increased (P ＜ 0.05).(2) The percentage of the medial plantar contact area accounting the total contact area of the foot was significantly increased with body mass index increasing (P ＜ 0.01);the percentage in the obese group was significantly higher than that in the normal group (P ＜ 0.05).(3) These results show that the plantar pressure and impulse are increased in overweight and obese subjects due to weight gain,and foot will appear with pathological changes with time going.Obese people suffer from arch drop due to weight gain,and increase in contact area of midfoot,which are easy to cause flatfoot.Overweight especially obese,should pay attention to control weight,do appropriate exercise,wear suitable shoes,protect the foot,further to prevent the occurrence of foot injury and flatfoot.

Compound algin capsule (CAC) was developed to treat the patients with Helicobacter pylori (HP)positive gastritis and digestive ulcer. The results showed that the e-liminating rate of HP was 67.4%,the disappeating rate of gastritis was 75%,and the ulcer healing rate 97. 8%. The symptom relief rate in CAC group was 88% ,which was significantly higher than the control group (68. 6% ,P

Objective To investigate the effects of catalase on expression of cytokines and activation of nuclear factor-?B in the intestinal mucosa in rat with ulcerative colitis(UC). Methods UC was reproduced in rats with the oral innoculation of dextran sulfate sodium (DSS).The expressions of TNF-?, IL-1? and IL-8 in the intestinal mucosa of rats were respectively determined by a semi-quantatitive assay, RT-PCR. The activation of NF-?B in the intestinal mucosa were assessed with electrophoretic mobility shift assay (EMSA). Results Comparing the mice challenged with DSS alone and to those treated with catalase, both symptoms and the lesions in the colonic mucosa were milder in the animals pretreated with catalase during the induction of colitis than that of control group and catalase treatment after induction of colitis group. Furthermore, the expressions of TNF-?, IL-1?, IL-8 were significantly down-regulated(P

Objective To study the effect of the tissue components purified from earthworm on the thioredoxin system and its pharmcological mechanism. MethodsAcetate buffer purified the tissue components from the earthworm. The catalyzing activity of the thioredoxin reductases was dynamically measured on the 340nm wavelengthby the NADPH, an indicator by means of the reaction between the tissue components and thioredoxin system. ResultsThe absorbency of the NADPH was almost unchanged in the process of the reaction between the purified tissue components of earthworm and the thioredoxin reductase. On the contrary, the solvent to purify earthworm liquid and the clear liquid from boiled purified earthworm liquid had not above mentioned function. ConclusionsThere are some kinds of proteins in the tissue components of the earthworm, which could inhibit the activity of the thioredoxin reductase.

Objective To investigate the enhancing effect of apolipoprotein C3 (APOC3) on THP-1 cell adhesion to aortas of mice.Methods Microsurgery was performed to separate the aorta of C57BL/6 mice in sterile condition.After stimulated by APOC3 (100 △g/ml) in vitro for 16 h,the aorta was allowed to adhere for 1 h with CFSE labeled THP-1 cells (1 ×106/ml).Then the adhesion effect was observed,and the expressions of vascular adhesion molecule 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1) were detected by immunohistochemical method.Results Adhesion effect of the mice aorta with THP-1 cells in the APOC3 stimulated group was stronger than the control group.Both the expressions of VCAM-1 and ICAM-1 in aortas were increased by APOC3,but the former was significantly up-regulated than the latter.Conclusion Apolipoprotein C3 could enhance THP-1 cell adhesion to aortas of mice.

AIM:To investigate whether Smad pathway participates the process of extracellular signal regulated kinase (ERK) induced the proliferation of vascular smooth muscle cells (VSMCs). METHODS: Human umbilical artery smooth muscle cells (hUASMCs) were divided into four groups: control group, PDGF (platelet derived growth factor) group, ERK blocking agent group and PDGF+ERK blocking agent group. MTT assay was used to detect the proliferation of hUASMCs (A value). Immunohistochemical technique was used to detect the expression of PCNA, phosphorylated ERK (p-ERK) and phosphorylated Smad2/3 (p-Smad2/3) protein in hUASMCs. The expression of Smad2/3 mRNA in hUASMCs was detected by RT-PCR. RESULTS: The proliferation of hUASMCs and the expression of PCNA, p-ERK and p-Smad2/3 proteins in hUASMCs in PDGF group were increased obviously than those in other groups (P

The web-based PBL teaching plan in pediatrics embodies the network learning environment and learning requirements.The basic design unit is a complete real case with certain width and depth,which can stimulate the students' interests of participation and guide students into a predetermined learning area to achieve desired learning objectives.The article dwelled on the compilation and implementation of the teaching plan of children bronchopneumonia.The first part:teachers showed the case in PBL site and proposed the questions.Students made the Powerpoint after studying and discussing in groups by PBL teaching website,QQ group,SMS platform,etc.The second part:students reported and discussed in groups; the teacher provided the new information and put forward the following-up problems; students consulted the documents and materials through the network again; finally teachers made comments on the results.During the teaching,network should be fully utilized and the questions should be proposed progressively at different levels.Teacher should play a guiding role and emphasize the students' autonomous learning.

Objective To investigate the diagnostic value of microRNA (miRNA) in peripheral venous blood for depressive disorder.Methods Real-time fluorescence quantitative PCR (RT-qPCR) was used to verify expression level of miRNAs in peripheral blood of non-specific mental retardation children,which were aberrantly expressed in depressive disorder patients,and then Receiver Operating Characteristics (ROC)curve was employed to confirm the sensitivity and specificity of abnormal miRNA expression in depressive disorder and non-specific mental retardation.Results MiR-1972,miR-26b,miR-4485,miR-4498 and miR-4743 were upregulated significantly in case group of depressive disorder(P＜0.05),meanwhile miR-4485 and miR-4743 in aforementioned 5 miRNAs also upregulated significandy in patients of non-specific mental retardation(P＜0.05),but miR-26b showed no significant difference between case group of non-specific mental retardation and the control group (P＞0.05).The ROC curve of miR-26b in depressive disorder patients and their control group showed that the sensitivity and specificity were 0.609,0.664 respectively,and the area square under the curve was 0.614(P=0.021).The ROC curve of miR-26b in patients of depressive disorder and non-specific mental retardation indicated that the sensitivity and specificity were 0.784 and 0.471,and area square under the curve was 0.643 (P=0.003).Conclusion miR-26b probably have diagnostic value for depressive disorder,which may comorbidity with non-specific mental retardation.But genetic and psychosocial mechanism of comorbidity still needs further exploration.
