Helicobacter pylori is able to colonize the human stomach and dwell in the human stomach for decades or for whole lifetime. A number of potential virulence factors contribute to Helicobacter pylori to colonize this unusual niche. Motility is an essential colonization factor based on the fact that nonmotile variants of Helicobacter pylori can't infect gnotobiotic piglets. Motility is not a colonization factor based on rapid loss of motility of Helicobacter pylori in the gastric lumen in vivo. The exact roles of Helicobacter pylori motility are not yet known. The aim of this article is to discuss correlation between colonization and motility of Helicobacter pylori.

Objective:To evaluate the effectiveness of psychological intervention on improving the survival quality of patients with endometrial cancer during the operation.

Objective To analyze the effects of individualized lifestyle intervention on compliance and metabolic status of patients with type 2 diabetes mellitus (T2DM).Methods Two hundred T2DM patients were selected and randomly divided into experimental and control groups of 100 patients respectively.The experimental group was given individualized lifestyle intervention for 6 months in addition to conventional oral medications.The intervention was to prescribe diet control and exercise therapy according to the patients' individual conditions.The control group was given conventional treatment and verbal lifestyle intervention for 6 months.Comparison was made in patients compliance and various metabolic markers between the two groups.Results The percentage of conduction of diet control and exercise therapy in experimental group was significantly higher than control group ( Diet control:80 vs.52,x2=7.08,P=0.029;Exercise therapy:78 vs.44,x2=11.207,P=0.004).After intervention,the fasting plasma glucose (FPG),2-hour postprandial blood glucose (2hPG),glycated hemoglobin ( HbA1c),body mass index ( BMI),triglyceride ( TG),total cholesterol (TC),low-density lipoprotein ( LDL-C ),and insulin resistance index ( HOMA-IR ) in experimental group decreased significantly,and high-density lipoprotein ( HDL-C ) increased significantly [FPG:( 8.45 ± 1.46 ) mmol/L vs.(6.66 ± 0.67) mmol/L,P=0.000;2hPG:( 12.76 ± 2.25 ) mmol/L vs.(8.22 ± 1.79) mmol/L,P=0.000;HbA1c:(7.68 ± 1.06 ) ％ vs.( 6.48 ± 0.69 ) ％,P=0.000;BMI:( 25.90 ± 1.72 ) kg/m2 vs.( 22.81 ±1.41 ) kg/m2,P=0.016;TG:(2.57 ±0.68) mmol/Lvs.( 1.88 ±0.35) mmol/L,P=0.006;TC:(5.72 ±0.13) mmol/L vs.(5.14 ± 1.38) mmol/L,P=0.043;LDL-C:(3.28 ±0.10)mmol/L vs.(2.81 ±0.57)mmol/L,P=0.009;HOMA-IR:7.58 ± 0.19 vs.4.58 ± 1.98,P=0.000;HDL-C:( 1.29 ± 0.04) mmol/L vs.( 1.62 ± 0.27 ) mmol/L,P=0.003].The levels of FPG,2hPG,HbA1c,BMI,TG,HOMA-IR also decreased in control group after intervention compared with before intervention [FPG:( 8.67 ± 2.71 ) mmol/L vs.( 7.26 ± 1.21 ) mmol/L,P=0.001;2hPG:( 12.82 ± 2.15 ) mmol/L vs.( 10.85 ± 1.98 ) mmol/L,P=0.000,HbA1c:( 7.75 ± 1.08 ) ％ vs.( 7.01 ± 0.87 ) ％,P=0.002;BMI:( 25.82 ± 1.74 ) kg/m2 vs.( 24.23 ± 1.36 ) kg/m2,P=0.024;TG:(2.47 ±0.75) mmol/L vs.(2.13 ± 0.43 ) mmol/L,P=0.018;HoMA-IR:7.88 ± 0.20 vs.6.15 ± 2.01,P=0.042].No significant difference was found on the values of TC,HDL-C and LDL-C before and after intervention in control group (P ＞ 0.05).The effect of intervention of experimental group was more obvious when compared with control group ( FPG:P=0.036;2hPG:P=0.000;HbA1c:P=0.045;BMI:P=0.037;TG:P=0.022;HoMA-IR:P=0.000).Conclusion Individualized lifestyle intervention can improve the compliance of T2DM patients,and was in favor of control metabolic status of T2DM patients to delay the occurrence and development of complications.

Objective To research the chronic respiratory infectious diseases caused by Pseudomonas aeruginosa need to objectively the reflection of the real environment in the body, so established a mouse model of chronic pulmonary infection with Pseudomonas aeruginosa and analyzed it's inflammatory response. Methods Establishment of chronic bronchial infection mice model that were inoculated with Pseudomonos aeruginosa-laden agarose beads, and analyzed its inflammatory response by detected the cytokines and MMP-2, and a differential cell count and a total leukocytes count were performed as well. Results Pseudomonas aeruginosa had been detected after infection, and there were changes in pathological. Pulmonary inflammation appeared in 1 d and reached near baseline levels by 7 d after inoculation. It was verified that the peak of inflammatory reaction in Pseudomonas aeruginosa infection is in 2-3 d; the mice did have detectable levels of circulating matrix metalloproteinase-2 ( MMP-2 ) after infection with Pseudomonas aeruginosa. MMP-2 concentrations in the blood serum peaked at 3 d after inoculation. It is indicated that Pseudomonas aeruginosa can initiate a certain degree of pulmonary fibrosis on the basis of the pulmonary inflammation. Conclusion In this study, chronic bronchial infection animal model affected by Pseudomonas aeruginosa was established successfully. Base on this animal model, we can do the pathogenicity and drug resistance of Pseudomonas aeruginosa further study.

Objective To investigate the role of RANKL/RANK/OPG system in bone metabolism of ankylosing spondylitis (AS) by detecting bone mineral density, bone metabolism factors such as osteoprotegerin (OPG), soluble receptor activator of nuclear factors-κB ligand (sRANKL) and the expression of membrane-bound (mb) RANKL in the peripheral blood T lymphocytes. Methods Bone mineral density of AS patients were measured by dual-energy X-ray absorptiometry (DEXA) and serum levels of OPG, sRANKL,tartrate resistant acid phosphatase 5b (TRACP-5b) and bone alkaline phosphatase (BALP) were determined by enzyme-linked immunosorbent assay (ELISA). The percentages of CD4+/RANKL+ and CD8+/RANKL+ in the peripheral blood were detected with flow cytometry. T-test, x2-test were used for statisical analysis. Results ① The incidence of osteopenia and osteoporosis in AS was 47% and 37% respectively. ② Serum RANKL,TRACP-5b levels and RANKL/OPG ratio were higher in AS patients than those in normal controls (P<0.05).But there was no significant difference in OPG and BALP between AS patients and normal controls. ③There were positive linear correlation between serum levels of RANKL and OPG, sRANKL and TRACP-5b, OPG and TRACP-5b in AS (P<0.01). ④ The prevalence of CD4+/RANKL+ cells in the peripheral blood of AS patients was significantly higher than that in the normal controls (P<0.05). Conclusion There is a high incidence of bone loss in AS patients. Increased bone resorbtion is the feature of bone metabolism in AS.RANKL/RANK/OPG system may play an important role. The imbalance of RANKL/RANK/OPG system may be one of the bone loss mechanisms of AS. CD4 + T lymphocyte may play an important role in osteoclasts differentiation and bone resorption in AS by up-regulating the expression of RANKL.

BACKGROUND:The kidney tissues easily affected exercise ischemia reperfusion, increased free radicals and inflammation, resulted in abnormal renal function after acute exercise. OBJECTIVE:To observe the influence of Blackcurrant Extract on the structure of kidney and expression of tumor necrosis factor-α and nuclear factor-κB at 24 hours after exhaustiveexercise. METHODS:A total of 30 male Wistar rats were randomly divided into three groups (n=10). Rats in the Blackcurrant Extract group were intragastricaly administered 0.44 g/kg Blackcurrant Extract. Rats in the quietness control group and 24-hour exhaustive exercise group were intragastricaly given an equal volume of distiled water for 6 consecutive weeks. Rats in the 24-hour exhaustive exercise group and Blackcurrant Extract group received no swimming motion until exhaustion fatigue after final intragastric administration. Twenty-four hours later, samples were obtained. Kidney tissue morphology and ultrastructure were observed by electron microscopy and light microscopy. Protein expression of tumor necrosis factor-α and nuclear factor-κB was detected using immunohistochemistry. Tumor necrosis factor-αmRNA and nuclear factor-κB mRNA expression was detected using RT-PCR. RESULTS AND CONCLUSION:Compared with the quietness control group, tumor necrosis factor-α protein and nuclear factor-κB protein expression in the kidney was higher in the 24-hour exhaustive exercise group, and tumor necrosis factor-α mRNA and nuclear factor-κB mRNA expression was significantly increased (P < 0.01). Compared with the 24-hour exhaustive exercise group, tumor necrosis factor-α protein and nuclear factor-κB protein expression was lower in the Blackcurrant Extract group, and nuclear factor-κB mRNA expression was significantly decreased (P < 0.05); tumor necrosis factor-α mRNA expression was significantly reduced (P < 0.01). Kidney in the 24-hour exhaustive exercise group showed obvious morphological changes and ultrastructural damage. The structure of the kidney in the Blackcurrant Extract group tended to be normal. Results suggested that Blackcurrant Extract can repair the kidney tissue injury, reduce the expression of inflammatory factors, and prevent inflammatory damage in the kidney at 24 hours after exhaustive exercise.
