Objective To observe the effects of ginsenoside Rg1 group on the structure and function of rat skeletal muscle with exercise-induced fatigue.Methods SD rats were randomized into blank control group,model group and ginsenoside Rg1 group.The rats in the model group and ginsenoside Rg1 group received medium-intensity treadmill running to induce exercise-induced fatigue.Ginsenoside Rg1 group was given ginsenoside Rg1 50 mg?kg-1?d-1 for 2 continuous weeks during the modeling.After treatment,malondialdehyde(MDA)content,superoxide dismustase(SOD) activity,mitochondrial membrane potential and free calcium content in the rat skeletal muscle were measured.Meanwhile,ultrastructure of the skeletal muscle was observed under the electron microscope.Results In the model group,SOD activity,mitochondrial membrane potential,and free calcium content were decreased,MDA content was increased,and the difference was significant as compared with the blank control group(P

Objective To explore the effect of neural cell adhesion molecule (NCAM) on adhesion,migration and morphology of mouse bone marrow-derived mesenchymal stem cells (BMSCs).Methods We isolated and cultured BMSCs from wild-type and NCAM gene knockout mice.The expression of NCAM was detected by Western blot and immunofluorescence.Wound healing and adhesion assays were used to detect cell migration and adhesion ability respectively.The morphological changes were observed and the expressings of protein β1 integrin,E-cadherin,β-catenin and N-cadherin were analysed by Western blot.Results The migration and adhesion of BMSCs were significantly reduced after NCAM gene knockout.Meanwhile,the expression of β1 integrin was lower than those in wild-type BMSCs (P<0.01).The morphology of NCAM gene knockout BMSCs changed from irregular to flattened,and expressed epithelial identification marker E-cadherin and β-catenin (P<0.05).However,the expression level of mesenchymal identification marker N-cadherin was decreased (P<0.01).Conclusions NCAM is involved in adhesion and migration of BMSCs via regulating the expression of β1 integrin.Furthermore,NCAMmay negatively regulate the mesenchymal-epithelial transitions of BMSCs.

Background and purpose:miR-124 is considered to be a tumor suppressor in multiple tumors, including lung cancer, prostate cancer, bladder cancer, and breast cancer. However, its function is unclear in gastric cancer. This study aimed to explore the expression of miR-124 in human gastric mucosal epithelium cells and different gastric cancer cells, as well as gastric cancer tissues and matched para-cancerous tissues. The correlations of miR-124 expression with gender, age, histological grade, T stage, TNM stage, lymph node metastasis and prognosis of gastric cancer patients were analyzed.Methods:A real-time lfuorescent quantitative polymerase chain reaction (RTFQ-PCR) was employed for detecting the expression of miR-124 in human gastric mucosal epithelium cells and gastric cancer cells. The expression of miR-124 in gastric cancer tissues and matched para-cancerous tissues was detected by in situ hybridization.Results:The RTFQ-PCR results indicated that the expression of miR-124 was down-regulated in MKN-74, MKN-28, MKN-45, MGC-803, SGC-7901 and AGS cells compared to GES-1 cells.In situ hybridization showed that miR-124 was strongly expressed in normal gastric mucosa. However, low expression, focal positive expression or lack of miR-124 expression were observed in gastric cancer tissues. Statistical analysis showed that miR-124 was close-ly correlated to histological stage, TNM stage and node metastasis of gastric cancer patients, but not the age, gender and tumor size. The OS and DFS of the patients with low expression of miR-124 were shorter than that of the patients with high expression of miR-124. Multivariate analysis suggested that miR-124 down-regulation was an independent prog-nostic factor for survival in patients with gastric cancer.Conclusion:miR-124 is down-regulated in gastric cancer cells and tissues. The expression of miR-124 is correlated to histological stage, TNM stage, node metastasis and prognosis.

BACKGROUND:More and more evidence suggests that macrophages and inflammation reactions are involved in the formation and development of nephrolithiasis. Previous studies have found that calculi crystals can stimulate macrophages to release high mobility group protein B1.
OBJECTIVE:To investigate the synergistic effect of high mobility group protein B1 in calcium phosphate induced release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.
METHODS:(1) The induced U937 cells were respectively stimulated with RPMI (blank), 100 mg/L calcium phosphate, 100μg/L high mobility group protein B1 and 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 1, 2 and 4 hours to col ect cellsupernatant. (2) The induced U937 cells were respectively stimulated with 100 mg/L calcium phosphate, 100 mg/L calcium phosphate+10μg/L high mobility group protein B1, 100 mg/L calcium phosphate+50μg/L high mobility group protein B1, 100 mg/L calcium phosphate+100μg/L high mobility group protein B1 for 4 hours to col ect cellsupernatant. Levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 were determined by ELISA.
RESULTS AND CONCLUSION:The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of 100 mg/L calcium phosphate group and 100μg/L high mobility group protein B1 group were both higher than those in the blank group in a time-dependent manner (P<0.05). The levels of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 in the cellculture supernatant of different concentrations of high mobility group protein B1 groups were al higher than those in the 100 mg/L calcium phosphate group in a concentration-dependent manner (P<0.05). The results suggest that both calcium phosphate and high mobility group protein B1 can induce the release of interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages and the high mobility group protein B1 has the synergistic effect with calcium phosphate to induce interleukin-1β, interleukin-6, tumor necrosis factorαand monocyte chemotactic factor 1 from human macrophages.

Objective To investigate the changes and mechanisms of immune function after ischemic stroke by studying the reaction of C57BL/6mice's lung and spleen after ischemic stroke.Methods Sixteen mice C57BL/6 were randomly assigned to experiment group (n=8) and control group (n=8).The acute ischemic stroke model was established in experiment group by Middle Cerebral Artery Occlusion (MCAO) and no stroke was performed in control group.Then we observed the lung inflammation by HE staining of the lung.And we measured the spleen weight,spleen weight index,the count and the apoptosis index of spleen cells of mice in two groups.Results Compared with the control group,the count of the inflammatory cells in lung of mice in the experiment group was higher,the spleen weight,spleen weight index and spleen cells count of the experiment group were decreased and the apoptosis index of spleen cells of the experiment group was higher.Conclusion The mice in the experiment group have inflammatory reaction in lung,the spleen atrophied and the apoptosis index of spleen cells is increased,which suggest that stroke-induced apoptosis of immunocytes may cause immunodepression after ischemic stroke and easily lead to the infection.

Purpose The diagnosis of adult onset Still's disease (AOSD) is usually difficult due to the lack of specific clinical manifestation.This paper summarizes the manifestations of 18F-FDG PET/CT in adult onset Still's disease and investigates the value of PET/CT in diagnosis and differential diagnosis of AOSD.Materials and Methods Fiftyfour patients who was diagnosed as AOSD were selected and underwent 1 8F-fluorodeoxyglueosepositron emission tomography/computed tomography (18F-FDG PET/CT).The clinical features,laboratory examination and the maximum standard uptake value (SUVmax) of liver,spleen,bone marrow,lymph node were collected.Then the main PET/CT manifestations of patients with AOSD,the influence factor of SUVmax and correlation between SUVmax and laboratory indexes were analyzed.Results FDG accumulation occurred mainly in bone marrow (88.89％;SUVmax:3.91 ± 1.16),spleen (79.63％,SUVmax:3.24±0.89) and lymph node (77.78％;SUVmax:3.83± 1.97).FDG accumulation can also occurred in joints,parotid gland,submandibular gland,pleural and other organs.Compared with the nonglucocorticoid group,SUVmax of the spleen,bone marrow and lymph node were significantly decreased in the glucocorticoid group with or without fever (P＜0.05),whereas the SUVmax of liver,spleen,bone marrow and lymph node between the two glucocorticoid groups were not statistically different (P＞0.05).The SUVmax of liver,spleen,bone marrow and lymph node between two groups with or without disease-modifying anti-rheumatic drugs were not statistically different (P＞0.05).Correlation analysis showed that spleen SUVmax and lactate dehydrogenase,bone marrow SUVmax and C reactive protein were weakly correlated (r=0.33 and 0.30,P＜0.05).Conclusion The main manifestations of 18F-FDG PET/CT of AOSD are FDG accumulation in spleen,bone marrow and lymph nodes.Glucocorticoid can reduce the SUVmax.18F-FDG PET/CT can help to rule out malignancy,guide biopsy and assist in definite diagnosis of AOSD.

Objective To evaluate urinary β2-microglobulin (β2-MG) and retinoid binging protein (RBP) in monitoring of early renal impairment in chronic hepatitis B (CHB) patients with long-term adefovir dipivoxil (ADV) treatment. Methods Three hundred and fifty five with CHB admitted in Shaoxing Municipal Hospital from June 2009 to June 2011 were enrolled in the study, among whom 180 cases study group) were treated with ADV monotherapy (n=100) or ADV + lamivudine (LAM) combination therapy (n=80); and 175 cases (control group) were treated with entecavir (ETV). Serum creatinine, urinary β2-MG, RBP and creatinine were measured and glomerular tration rate (eGFR) was estimated regularly during 5-year follow up. Kaplan-Meier method was used to calculate the cumulative incidence of changes in urinary β2-MG and RBP. Results Five-year follow-up results showed that in study group 2, 6, 10, 14 and 24 cases developed urinary β2-MG abnormality in year 1, 2, 3, 4 and 5 of treatment, respectively; and 2, 7, 11, 16 and 20 cases developed urinary RBP abnormality in year 1, 2, 3, 4 and 5 of treatment, respectively; eGFR decreased 20%-30% from baseline in 20 cases, 30%-50% in 13 cases and >50% in 2 cases. The decrease of eGFR ≥30% in 5 years was significantly correlated with urinary RBP and β2-GM abnormality. However, both serum creatinine and eGFR remained stable during the 5 years of follow-up in control group; only 2 cases developed urinary β2-MG abnormality and 3 cases developed urinary RBP abnormality. Conclusions Urinary RBP and β2-MG are sensitive biomarkers of early renal injury during long-term ADV treatment in CHB patients, and ADV should not be used as first-line treatment for CHB.
