Objective:To study the expression and clinical significance of GPRC5A and SOCS3 in colorectal carcinoma.Methods:SP immunochemical method was performed to detect the expression of GPRCSA and SOCS3 in 45 cases of colorectal carcinoma,25 cases of colorectal adenomas and 22 cases of normal colorectal tissues.Results:1)Expression of GPRC5A in colorectal cancinoma tissue (22.2％) was significantly lower than that in adenomas tissue (52.0％,P＞0.05).The Latter was significantly lower than that in normal colorectal tissue (81.8％,P＜0.05).GPRC5Awas closely related to lymph node metastasis,Duke's stages and the deepness of invasion (P＜0.05).2) Expression of SOCS3 in colorectal cancinoma tissue (24.4％) was significantly lower than that in adenomas tissue (56.0％,P＜0.01).The Latter was significantly lower than that in normal colorectal tissue (86.4％,P＜0.05).SOCS3 was closely related to pathological differentiation,the deepness of invasion,Duke's stages and lymph node metastasis (P＜0.05).3)The expression of GPRC5A was positive correlated with SOCS3 (P＜0.05).Conclusions:The reduced expressions of GPRC5A and SOCS3 may participate in the occurence and development of colorectal carcinorma,suggesting that GPRC5A and SOCS3 may act as biological markers for evaluating the malign degree,prognosis and therapeutic targets of colorectal carcinorma.

Objective To provide clinical experience in the treatment and prevention of complicated acute cardiac tamponade in the course of heart interventional therapy. Methods To analyse the clinical features of patients with acute cardiac tamponade and to investigate the possible underlying mechanism. Results Twenty-one cases experienced acute cardiac tamponade when undergoing heart interventional therapy. Among all the 21 patients with acute cardiac tamponade, 11 occurred from percutaneous coronary interention(PCI) ,6 from the radiofrequency catheter ablation , 1 from the closure of atrial rspetal with amplaty closure service, 1 from the percutaeous balloon mitral valvuloplasty ( PBMV), 2 from temporary pacemaker implantation. Eighteen patients were successfully rescued left no serious sequelae. Three cased died, including two PCI-related death and one temporary-pacemaker-installation-related death. Conclusion Any heart interventional operation is at the risk to cause acute cardiac tamponade. Early identification and appropriate treatment is the key to successful rescue.

Background:Irritable bowel syndrome( IBS ) is one of the most common functional gastrointestinal disorders. Analyzing the regional differences of symptomatic profiles may provide guidance for the diagnosis and treatment of IBS. Aims:To preliminarily investigate the symptomatic characteristics of IBS patients in Fujian province,China for the reference of diagnosis and treatment of the disease. Methods:A total of 703 IBS out-patients based on the RomeⅢcriteria and presented to the gastroenterological clinic of 15 tertiary hospitals in Fujian Province,China from Jun. 2011 to Apr. 2012 were enrolled in a face-to-face survey. The questionnaire mainly included demographic data,course of the disease, and clinical symptoms. Results:In 703 IBS patients,the ratio of male to female was 1:1. 3,and the peak of age was 35-45 years(32. 4%). More than half of the patients were diarrhea-predominant IBS(IBS-D,58. 2%),while constipation-predominant IBS( IBS-C)accounted for 22. 6% of the patients. Abdominal pain/discomfort,abdominal distention and abnormal defecation,including diarrhea,constipation,feeling of incomplete defecation and mucous stool were the most important lower GI symptoms. In the four subtypes of IBS,the symptoms of mixed IBS( IBS-M)were most serious( P<0. 05). Compared with IBS-C,abdominal pain was more severe in IBS-D and IBS-M(P<0. 05),however,abdominal distention was more severe in IBS-C than in IBS-D(P<0. 05). About one third of the patients(32. 9%)were overlapped with upper GI symptoms,and the most common upper GI symptoms were postprandial fullness and eructation. Sixty-eight (9. 7%)patients were overlapped with functional dyspepsia. Conclusions:In Fujian Province,China,more than half of the IBS patients were IBS-D. The symptomatic profiles are different between different subtypes of IBS. Some of the IBS patients may be overlapped with upper GI symptoms or functional dyspepsia.

Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.

OBJECTIVE:To study the curative effects of Shenyanqing tablet.METHODS:1 200 patients with chronic glomerulonephritis,acute glomerulonephritis,latent glomerulonephritis and purpura glomerulonephritis were randomized into the treatment group and control group,and separately studied on curative effects and reduction of adverse reaction of glucocorticosteroid.In the study of curative effects,the control group received no special treatment except that on reducing pressure and diuresis,and the treatment group was given Shenyanqing tablet,8 tablets? d-1,tid,in addition to receiving same treatment as that for the control group.In the study of reducing adverse reaction of glucocorticosteroid,the control group(the treatment group was the same as the method above)was given normal glucocorticosteroid treatment for 3 months and 2 months respectively.RESULTS:It has significant difference(P

AIM:To investigate the roles of ClC-3 chloride channels in the regulation of cell cycle and the re-lationship between ClC-3 chloride channels and the cell cycle regulators , such as cyclin D1, cyclin-dependent kinase (CDK)4, CDK6, P21 and P27 in the HeLa cells.METHODS:ClC-3 genes were silenced by the siRNA technique in the HeLa cells.The transfection efficiency of ClC-3 siRNA was detected by real-time PCR.The cell cycle distribution was ana-lyzed by the flow cytometry .The protein expression of ClC-3, P21, P27, CDK4, CDK6 and cyclin D1 was determined by Western blot .RESULTS:ClC-3 was knocked down by ClC-3 siRNA in the HeLa cells .Transfection of the cells with ClC-3 siRNA arrested the cells at G0/G1 phases, decreased the expression of cyclin D1, CDK4 and CDK6, and increased the expression of P21 and P27.CONCLUSION:ClC-3 plays an important role in the cell cycle of HeLa cells through the G 1-S transition point.ClC-3 may regulate the cell cycle progression by up-regulation of cyclin D1, CDK4 and CDK6 expression and/or by down-regulation of P21 and P27 expression.

Objective To explore the clinical efficacy of proximal femoral locking compression plate (LCP)fixation in elderly intertrochanteric fractures patients. Methods 30 cases of intertrochanteric fracture fixed with LCP were collected,and the functional recovery of all hip joints was observed. Results The average follow-up and healing time of all cases was 10 months(6 to 14 months)and 3.5 months respectively. Hip joint function of 27 cases was excellent( Harris scoring≥90) ,that of the other 3 cases was good ( Harris scoring:80 ～ 89). Conclusion The proximal femoral LCP fixation had a good clinical value in treatment of elderly intertrochanteric fracture patients. It had many advantages, such as simplicity, rigid fixation, less trauma and bleeding, shorter operative time, less complications, high heal rate, etc.
