Breast cancer metastasis suppressor gene 1 (BRMS1) significantly reduces the invasion and metastasis of cancer cells.BRMS1 gene expression is decreased or deleted in the cells of various malignant tumors.BRMS1 gene can inhibit tumor cells invasion and metastasis by means of regulating gene transcription and protein translation by phosphoinositide signaling and nuclear factor-κB (NF-κB) signaling pathways,repairing intercellular communication and interacting with the mSin3-histone deacetylase (HDAC) complex,estrogen receptor and other proteins.BRMS1 gene may be a new target for the gene treatment of tumor metastasis.

Objective To analyze the validity of Caprini venous thrombosis risk assessment model (Caprini RAM) in the tunneled cuffed dialysis catheters (TCCs) dysfunction patients with central venous thrombosis (CVT).Methods A total of 187 maintenance hemodialysis patients with TCCs dysfunction admitted to West China Hospital of Sichuan University from January 2013 to September 2016 were analyzed retrospectively.According to the chest computed tomography venography results,patients were divided into CVT group and non CVT group.Their general clinical data (age,gender,primary diseases,history of dialysis access,etc.),blood biochemical data (hemoglobin,serum albumin,blood lipid,etc.) and 40 risk factors of Caprini RAM were collected.Caprini RAM scores were computed for risk stratification of thrombosis.Two groups were compared to analyze the value of Caprini RAM in these patients by statistics.Results One hundred and twenty CVT patients and sixty-seven non CVT patients were enrolled.In CVT group the duration of dialysis,hemoglobin and hematocrit were higher than those in non CVT group (all P < 0.05).There was no significant difference between the two groups in gender,age,primary diseases,duration of catheter dependence,catheter tip position,usage of urokinase (all P > 0.05).The average score of Caprini RAM in CVT group and non CVT group did not show statistical difference (6.23+ 1.81 vs 6.19+ 1.95,P=0.913).All patients were stratified into higher risk level and highest risk level according to Caprini RAM.Higher risk level patients accounted for 18.18% and highest risk level patients accounted for 81.82%.As patients with inequable Caprini RAM scores,their incidence of CVT did not differ statistically (x2=0.105,P=0.746).CVT incidence rate of higher risk level patients was 61.76%,and of highest risk level patients was 64.70%.Conclusions Caprini RAM verifies that maintenance hemodialysis patients with TCCs dysfunction have high risk of venous thrombosis,but this model fails to distinguish patients between CVT group and non CVT group.Its clinical diagnosis is relatively limited and needs to be further explored.

OBJECTIVEWe detected and analyzed the clinical values of total protein (TP), albumin (ALB), globulin (GLB), and ALB/GLB ratio (A/G) of whole unstimulated saliva of healthy people to determine the time of day when saliva composition is relatively stable. We compared the protein concentration and A/G of whole unstimulated saliva of patients with chronic periodontitis with those of healthy volunteers to provide references for diagnostic methods and clinical applications of saliva.
METHODSThe whole saliva of 37 healthy subjects were collected at 8:00, 9:30, 11:30, 13:00, 16:30, and 21:00. Meanwhile, the whole saliva of 24 patients with periodontitis was collected in the morning. Bicinchoninic acid method was used to detect the TP content. Saliva ALB was detected by GF-D800 semi-automatic biochemical analyzer, and the GLB and A/G were calculated. Finally, the results were statistically analyzed using SPSS 19.0.
RESULTSSalivary protein compositions were stable in the morning on an empty stomach. Healthy people: TP, (1 354.35±389.52) µg.mL-1; ALB, (139.55±27.19) µg.mL-1; GLB, (1 211.80±360.73) µg.mL-1; A/G, 0.126 3±0.041 7. Subjects with chronic periodontitis: TP, (2 611.56±231.62) µg.mL-1; ALB, (296.27±17.34) µg.mL-1; GLB, (2 315.69±221.67) µg.mL-1; A/G, 0.156 2±0.017 3. The contents of TP, ALB, and GLB in healthy individuals at different periods within a day showed significant differences (P<0.05), which were mainly reflected in the levels before and after meals. No significant difference was detected in A/G. The concentrations of TP, ALB, and GLB were significantly increased in patients with chronic periodontitis compared with those in healthy volunteers. However, no significant difference existed in A/G.
CONCLUSIONSalivary protein compositions are more stable in the morning than in other periods. Thus, mornings can be set as the time of specimen collection in future research. The concentrations of TP, ALB, and GLB in patients with chronic periodontitis are higher than those in healthy people.

The aim of this study was to investigate the effect of Bu-Shen-An-Tai recipe (BSATR) and its two components (Bushen recipe, and Huoxue recipe) on endometrial morphology during peri-implantation in superovulated mice. Mice were randomly divided into five groups, including the normal (N), model (M), Bushen (BS), Huoxue (HX) and Bu-Shen-An-Tai (BH) groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density (MVD) and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the endometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes (Bushen, Huoxue and BSATR) could improve the endometrial environment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.

An increasing number of monopartite begomoviruses are being identified that a satellite molecule (DNAbeta) is required to induce typical symptoms in host plants. DNAbeta encodes a single gene (termed betaC1) encoded in the complementary-sense. We have produced transgenic Nicotiana benthamiana and N. tabacum plants expressing the betaC1 gene of a DNAbeta associated with Tomato yellow leaf curl China virus (TYLCCNV), under the control of the Cauliflower mosaic virus 35S promoter. Transgenic plants expressing betaC1 showed severe developmental abnormalities in both species. Microscopic analysis of sections of both transgenic and non-transgenic N. tabacum leaves showed abnormal outgrowths of transgenic N. tabacum to be due to disorganized cell division (hyperplasia) of spongy and palisade parenchyma. Immuno-gold labeling of sections with a polyclonal antibody against the betaC1 protein showed that the betaC1 protein accumulated in the nuclei of cells. The possible biological function of the betaC1 protein was discussed.

Objective To explore the effects of intra-jugular vein dual lumen catheter lock heparin in different concentrations on the coagulation function,hemorrhagic tendency and catheter thrombosis risk in hemodialysis patients,and to investigate the reasonable lock heparin cuncentration. Method Ninety end stage renal disease (ESRD)patients receiving regular hemodialysis were enrolled and randomly assigned into 3 groups(n=30):Group A(pure heparin lock solution,6250 U/m1),GrouP B(medium heparin lock solution,1040 U/ml)and Group C(low hepafin lock solution,625 U/ml).The coagulation indexes were determined in short term.Complications such as bleeding,thrombosis,infection and thrombocytopenia were monitored.Results Prothrombin time(PT),actiwtted partial thromboplastin time(APTT)and thrombin time (TT)were significantly prolonged in Group A(P<0.01);only APTT was signifieanlly prolonged in Group B:however,no significant changes were observed in Group C.Hemorrhage risk was much higher in Group A than that in Group B and C (26.7%vs 10%and 0.P<0.05).Catheter thrombosis incidence was significantly higher in Group C than that in Group A and B(23.3%vs 0and 10%,P<0.05).Only 1 suspected catheter related infection was found in Group C,and 2cases of moderated thrombocytopenia in Group A. Concltrsion Moderate concentration of lock heparin solution has the best balance of hemorrhagic and thrombotic risk,and should be recommended to most of regular hemodialysis patients.

In MAST (mRNA accessible site tagging),the DNA tags from synthesized library were employed for identifying mRNA accessible sites. A large number of tags were amplified and subcloned for sequencing to verify mRNA binding profiles. A PCR was designed by using one primer which bridges over the tag terminal sequences. In PCR reaction DNA tag fragments were concatemerized by a bridge primer in reaction cycles. The concatemerized tag fragments were subcloned and sequenced. Dozens of the concatemerized sequences contained thousands tags. The PCR was a simple,effective way which for sequencing tags in a high through put manner.
