To investigate the expression of ICAM 1 and TNF ? in gastric mucosal cell during drug induced mucosal injury, the authors carried out the study in SD rats with aspirin by mouth with immunohistochemical method . The results showed that ICAM 1 began to express at 30min after administration of aspirin, peaked at 1h, maintained until 6h, decreased at 12h,and expressed slightly at 24h . TNF ? began to express at 15min, peaked at 3h to 6h,decreased at 12h, and expressed significantly at 24h. There was a slight ICAM 1 and TNF ? expression in gastric mucosal cells in the control group. It was suggested that the expression of ICAM 1 and TNF ? plays an important role in the mechanisms of gastric mucosal injury .

The effect of iodinated contrast on thyroid function and auto-antibodies after a single percutaneous coronary intervention (PCI) was explored.In 96 patients with randomly selected PCI,serum TSH,T3,T4,thyroid peroxidase antibody (TPOAb),thyroglobulin antibody (TgAb) were determined preoperatively as well as by 3-6 months postoperatively.After PCI,the level of TSH,T3,T4,showed no significant changes; TgAb,TPOAb which were positive preoperatively,after 3-6 months were statistically increased(P<0.05).Iodinated contrast in PCI has no significant influence on thyroid function and auto-antibodies after 3-6 months.

Objective To estimate the effect of glycoprotein (transmembrane) nonmetastatic melanoma protein B (GPNMB) on the proliferation and migration of as well as melanogenesis in melanoma cells.Methods The expression of GPNMB was detected by immunofluorescence assay in two melanoma cell lines M14 and G-361,as well as in primary human melanocytes.Then,the three kinds of cells each were classified into three groups:experimental group treated with small interfering RNA targeting GPNMB (GPNMB-siRNA),negative control group treated with the negative control siRNA,blank control group remaining untreated.Methyl thiazolyl tetrazolium (MTT) assay,transwell invasion assay and spectrophotometry were performed to evaluate cell proliferation activity,invasion potential and melanin levels,respectively.Statistical analysis was done using Student's t test.Results GPNMB was expressed in both melanoma cells and melanocytes.The transfection with GPNMB-siRNA down-regulated the mRNA and protein expressions of GPNMB in,and markedly suppressed the proliferation and migration of,melanoma cells.In detail,the proliferative activity (expressed as the absorbence value at 570 nm) of M14 and G361 cells was reduced by 35% and 40% respectively,the migration activity of M14 and G361 cells by 49% and 51% respectively,and the melanin levels in melanocytes,M14 cells and G361 cells by 73%,82% and 69% respectively,in the experiment group compared with those in the blank control group.Conclusions The siRNA-mediated silencing of GPNMB could effectively inhibit the proliferation of,invasion of and melanogenesis in melanoma cells,which suggests that GPNMB plays critical roles in the initiation and progression of melanoma.

Electrocardiogram (ECG) signals are susceptible to be disturbed by 50 Hz power line interference (PLI) in the process of acquisition and conversion. This paper, therefore, proposes a novel PLI removal algorithm based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD). Firstly, according to the morphological differences in ECG waveform characteristics, the noisy ECG signal was decomposed into the mutated component, the smooth component and the residual component by MCA. Secondly, intrinsic mode functions (IMF) of PLI was filtered. The noise suppression rate (NSR) and the signal distortion ratio (SDR) were used to evaluate the effect of de-noising algorithm. Finally, the ECG signals were re-constructed. Based on the experimental comparison, it was concluded that the proposed algorithm had better filtering functions than the improved Levkov algorithm, because it could not only effectively filter the PLI, but also have smaller SDR value.

OBJECTIVETo compare the efficacy between eccentric fixation and internal fixation for treatment of intertrochanteric fractures of femur,to provide a theoretical basis for the selection of the treatment method of the intertrochanteric fractures of femur.
METHODSFrom February 2007 to January 2010,82 patients with femoral intertrochanteric fracture were treated by internal fixation including 39 cases of eccentric fixation involving 23 males and 6 females, aged from 41 to 81 years old with an average of (62.68±10.69), using the DHS or proximal femoral locking plate; 43 cases of intramedullary fixation involving 15 males, 28 females,aged from 43 to 78 years old with an average of (62.60±8.37),using PFN or PFNA fixed. The surgical incision length, operative time, blood loss and postoperative Harris score between two groups were compared.
RESULTSThe wound of two groups were primary healing without operative complications. All cases received follow-up for an average time of 18.3 months (12 to 28 months). The incision length, operative time and blood loss had a statistically significant difference between two groups (P<0.05). Harris scores of hip joint function at 1 month after operation had statistically significant difference between two groups (P<0.05), and Harris scores at 12 months after operation had no statistical significance difference between two groups. The rate of excellent and good was 89.7% in eccentric fixation group and 90.7% in intramedullary fixation group,the difference was not statistically significant (t=0.0613, P>0.05). In eccentric fixation group, there was 1 case of fracture nonunion with DHS loose and ensuing hip varus deformity. In intramedullary nail fixation group, there was no anti-rotation out,distal intramedullary nail of femoral refracture occurred in 1 case.
CONCLUSIONTwo treatment methods for the treatment of femoral fractures had a good therapeutic effect,but the intramedullary fixation had shorter operative time and less blood loss than the eccentric fixation,it prior to apply to osteoporosis and unstable femoral intertrochanteric fractures.

Objective To investigate the aberrant methylation and expression of growth arrest and DNA-damage-in-ducible 45 gamma (GADD45G) gene in gastric cardia adenocarcinoma (GCA). Methods Bisulfite conversion-methylation specific polymerase chain reaction method (BS-MSP) and immunohistochemistry method were used respectively to detect the methylation status and protein expression of GADD45G in 138 GCA tumor tissues and corresponding normal tissues. Re-sults The methylation status of GADD45G distal promoter (region 1) was not detected in GCA tumor tissues and corre-sponding normal tissues. For GADD45G region 2 and region 3, the BS-MSP results of region 3 were identical to that of re-gion 2. The methylation frequency of proximal promoter and exon 1 in GADD45G island 2 (region 2 and region 3) in GCA tu-mor tissues (49.3%, 68/138) was significantly increased compared to that in corresponding normal tissues (0, P<0.01). The methylation status of this two sites in tumor tissues was associated with TNM stage of tumors (P<0.05). The protein expres-sion of GADD45G in tumor tissues was significantly decreased than that in corresponding normal tissues (P < 0.05),and threre was a significant negative correlation with methylation status of GADD45G proximal promoter and exon 1 (rs=-0.398). Conclusion The decreased expression of GADD45G by hypermethylation of proximal promoter exon 1 of the gene may play an important role in gastric cardia adenocarcinoma.

The aim of the study was to evaluate the efficacy and safety of phloroglucinol in treatment of abdominal pain caused by acute gastroenteritis.Three hundred patients with acute abdominal pain were randomly assigned to receive 80 mg intravenous infusion of phloroglucinol injection ( treatment group,n =150 ) or 10 mg anisodamine injection (control group,n =150).The pain intensity was estimated by the VAS scores before and after the injection,meanwhile adverse reactions were also recorded.The results showed that the pain intensity was relieved significantly after 1h of the injection in both groups(P <0.01).The effective rate of phloroglucinol was 84.1% (126/150),while that of anisodamine was 80.0% (120/150).The adverse reactions of treatment group were lower than that of control group( all P <0.01).The results indicate that phloroglucinol can effectively relieve abdominal pain caused by acute gastroenteritis with safety.
