Objective To explore pre-thrombosis state in patients with cor pulmonale and the efficacy of anticoagulant treatment with low molecular heparin(LME). Methods 54 patients with cor pulmonale were divided into LMH treatment group and routine treatment group, each group containing 27 patients. The concentrations of Von Willlebrand factor (VWF),prethrombin F 1+2 fragment(F 1+2 ),Fibrinogen(Fg),granule membrane protein(GMP-140)and D-dimer fragment(DD)were measured before and after treatment. Results The concentrations of WF,F 1+2 ,Fg,GMP-140 and DD in the patients with cor pulmonale were significantly higher than those in the controls. In LMH treatment group, the above indices and PaCO 2 markedly decreased and PaO 2 obviously increased, while in routine treatment group, PaCO 2 and PaO 2 slightly improved, and no change was observed in coagulation indices. Conclusion Early detection and diagnosis of pre-thrombosis state in patients with cor pulmonale and immediate treatment with LMH can be beneficial to the prognosis of these patients in acute stage.

Diffuse sclerosing variant papillary thyroid carcinoma,one of the variants of papillary thyroid carcinoma,nearly account for 0.7％ to 6.6％ of papillary thyroid carcinoma.It is an aggressive tumor that shows higher rates of recurrence,metastasis and persistent disease compares to classic papillary thyroid carcinoma,thus diffuse sclerosing variant papillary thyroid carcinoma needs stricter and more exhaustive operation.Since the incidence of diffuse sclerosing variant papillary thyroid carcinoma is low,many physicians lack of understanding of the disease,it's often missed diagnosis or misdiagnosed.Consequently.In order to let physicians understand more about diffuse sclerosing variant papillary thyroid carcinoma,this paper will elaborate the epidemiology,clinic and pathology features of it.

AIM:Cyclin is a decisive factor of regulating cell cycle,and RNA interference as an effective and specific gene silencing technique,can induce cell express the phenotype of specific gene deficiency. This study is to apply cyclinD1 specific small interfering RNA(siRNA) on inhibiting cyclinD1 gene expression and investigate the effect of cyclinD1 specific siRNA on the cell cycle and multiplication in keloid fibroblasts. METHODS:The experiment was conducted at the Institute of Genetic Engineering(Grade BSL-2) in Southern Medical University from July 2006 to May 2007.①siRNA was designed with siRNA target finder of ambion Company,and synthesized chemically in Shanghai GeneChem,Co.,Ltd. Then double-strand siRNA was obtained following degenerative renaturation. Keloid fibroblasts were sampled from the patients in the Department of Plastic Surgery,Southern Medical University(informed consents were obtained from the patients or their relatives).②The keloid fibroblasts were divided into experimental group and control group. The cyclinD1 specific siRNA was transfected into the keloid fibroblast of the experimental group by the liposome-mediated gene transfection method. The untreated cells were set as controls.③At hours 24,48 and 72 of transfection,light microscope was used to observe cell morphologic change and flow cytometry was used to examine cell cycle. The viable cells were counted by MTT colorimetry and a cell growth curve was drawn. RESULTS:①Abnormal change of cell morphology that became into spherical shape or oval-shape from normal long fusiform after transfection may be the apoptosis or necrosis cells.②The G1 stage of cell cycle extended and the S stage decurtated. At 24,48 and 72 hours after transfection,the radio of G1 stage cell was 60.13%,66.22% and 67.53%,which were all significantly higher than that in the control group(54.53%);the radio of S stage cell(18.25%,17.11% and 11.15%) was also significantly lower than that in the control group(22.31%),indicating that the proportion of the cells blocked in G1 stage and those in S stage decreased in the keloid fibroblast.③siRNA-cyclinD1 inhibited the growth of keloid fibroblasts obviously by using MTT assay,and the cell growth curves indicated that the proliferation of cell transfected with cyclinD1 specific siRNA was inhibited significantly when compared with controls. CONCLUSION:CyclinD1 specific siRNA effectively inhibits the expression of cyclinD1 in keloid fibroblasts thus arresting the cell cycle at G1 stage and enhancing cell apoptosis.

Objective To investigate the effects of pulsed electromagnetic fields (PEMF) on osteogenic differentiation in demineralized bone matrix (DBM)-induced human marrow stromal cells (hMSCs).Methods hMSCs were obtained from iliac crest marrow aspirates of a healthy boy aged 14.Then 1?104 hMSCs per well were plated in 8 24-well tissue culture plates,and 1?105 hMSCs per well in 2 6-well plates after they were expanded until passage 2.Those 24-well plates and 6-well plates were divided into 4 groups,cell control group (C group),cell-material group (CD group),cell-PEMF group (CP group) and cell-material-PEMF group (CDP group).CD group and CDP group were added with one DBM (size of 5 mm?5 mm?3 mm),CP and CDP groups were exposed to the PEMF (frequency of 15 Hz,intensity of 5 Gs),and hMSCs were cultivated in subculture medium with full media exchange in every 3 d.Alkaline phosphatase (ALP) activity and osteocalcin (OC) level were performed at 1,7,14 and 21 d,and alizarin red staining and counting of calcium nodules were performed at 21 d.Results Significant differences in ALP activity and OC level were observed between cell control group and the other 3 groups in 7 d after treatment (P

Objective To investigate the effect of propofol on the liver function of offspring rats de?livered by cesarean section. Methods Twenty?four Sprague?Dawley rats, at 20 days of gestation, weig?hing 230-270 g, were divided into 4 groups ( n=6 each) using a random number table: control group (group C), propofol 2.0 mg∕kg group (group P2), propofol 4.0 mg∕kg group (group P4), and propofol 8.0 mg∕kg group (group P8). In P2, P4 and P8 groups, the corresponding doses of propofol were injected intravenously, and the cesarean section was performed at 30 min after loss of righting reflex. In group C, the pregnant rats were sacrificed by cervical dislocation at the corresponding time point, and the offspring rats were removed immediately and inhaled oxygen sufficiently. The neonatal rats were sacrificed immediate?ly, and the blood samples were taken from the heart for determination of plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) concentrations, and the livers were removed and cut into sections which were stained with haematoxylin and eosin for microscopic examination of the pathological changes. Results Compared with group C, the plasma ALT and AST concentrations in the offspring rats were significantly increased in P2, P4 and P8 groups (P<0.05). Compared with group P2, the plasma ALT and AST concentrations in the offspring rats were significantly increased in P 4 and P 8 groups ( P<0.01). Compared with group P4, the plasma ALT and AST concentrations in the offspring rats were signifi?cantly increased in group P8 (P<0.01). In P2, P4 and P8 groups, marked pathological changes of liver tissues were observed, and the severity was gradually aggravated in turn in offspring rats. Conclusion Propofol can induce damage to the livers of offspring rats delivered by cesarean section in a dose?dependent manner.
