Aim To investigate the protective effect of cinnamic aldehyde ( CA ) on hormone-induced osteo-clasts proliferation and bone resorption in vitro and its molecular mechanisms. Methods RAW264. 7 cells induced into osteoclast were treated with RANKL and M-CSF and then were divided into control group, dexa-methasone ( DEX ) group and different doses of CA (11. 6, 23. 2, 46. 4 μg·L-1 ) groups. OCs were ob-served after tartrate resistant acid phosphatase( TRAP) staining. The cell proliferation was determined by MTT assay at different time points. The expression levels of TRACP5 b in cell cultured supernatants were measured by ELISA. RT-PCR technique was applied to examine the transcriptional levels of RANK and NFATc1 . Re-sults In MTT assay, the proliferation of osteoclasts stimulated by dexamethasone was promoted seriously compared with negative control group ( P < 0. 05 ) . Meanwhile, DEX could strengthen the content of TRACP5 b and up-regulate the expressions of RANK and NFATc1 mRNA. After administration of CA, the proliferation was inhibited, while the enhanced expres-sion of TRAP5b was reversed,and the over-expressions of RANK and NFATc1 mRNA were obviously down-regulated in a time-and-dose-dependent manner ( P <0. 05 ) . Conclusion The results suggest that CA in-hibits proliferation and bone resorption of osteoclast in-duced by DEX, which may be mediated by down-regu-lation of RANK and NFATc1 mRNA.

Objective To assess the predictive value for survival of BioCliM index in liver cirrhosis caused esophageal and gastric varices bleeding(EGVB)treated by endoscopic variceal ligation(EVL),endoscopic injection sclerotherapy(EIS)and endoscopic tissue adhesives(ETA).Methods From December 2006 to December 2011, the clinical data of 166 hospitalized patients with first occurrence of EGVB caused by liver cirrhosis and received endoscopic therapies were retrospectively analyzed.The scores of model for end-stage liver disease(MELD),model for end-stage liver disease-Na(MELD-Na),BioCliM index and Child-Turcotte-Pugh(CTP)were calculated. Receiver operating characteristic(ROC)curve and area under the curve(AUC)were applied to assess the accuracy of the four models in one-year and two-year prognosis evaluation,and to obtain the best critical value,and the mortality rates were compared among groups.Chi-square test,t test and rank-sum test were performed for statistical analysis.Results Among 166 patients,the levels of creatinine,bilirubin,albumin,sodium,international normalized ratio and prothrombin time were(0.10 ± 0.06)mmol/L,(0.02 ± 0.01)mmol/L,(30.13 ± 5.06)g/L, (139.13 ± 4.27)mmol/L,1.50 ± 0.32 and(17.83 ± 2.88)s,respectively.During the one-year and two-year follow-up,there were 14 patients and 23 patients dead,respectively.During the one-year and two-year follow-up, the incidences of portal thrombosis of death group were lower than those of survival group(10/14 vs 93.4%,142/152;73.9%,17/23 vs 94.4%,135/143);and the differences were statistically significant(χ2=8.029 and 10.774, both P<0.01).During the one-year and two-year follow-up,BioCliM indexes of death group were 0.12(-0.82, 1.44)and -0.81(-0.87,0.92),respectively,which were both higher than those of survival group(-0.84,-0.94 to -0.73;and -0.84,-0.94 to -0.72),and the differences were statistically significant(Z= -3.074 and -2.260,both P<0.05).During the one-year follow-up,the AUC values of MELD,MELD-Na,BioCliM index and CTP score were 0.698,0.691,0.749 and 0.723,respectively.During the two-year follow-up,the AUC values of MELD,MELD-Na,BioCliM index and CTP score were 0.587,0.582,0.647 and 0.633,respectively. But there was no statistically significant difference in AUC between BioCliM index and MELD,MELD-Na,and CTP score in one-year and two-year follow-up for prognosis evaluation(Z=0.509,0.566,0.271,0.687,0.731 and 0.162,respectively;all P>0.05).The best critical value of BioCliM index was -0.234.Followed up for one year and two years,the mortality rates of patients with BioCliM index over -0.230 were higher than that of patients with BioCliM index less than -0.234(31.0%,9/29 vs 3.6%,5/137;34.5%,10/29 vs 9.5%,13/137);and the differences were statistically significant(χ2=23.242 and 12.526,both P<0.01).Conclusions BioCliM index has a high accuracy in one-year and two-year mortality rate evaluation in liver cirrhosis patients with EGVB and received endoscopical therapies.We should pay attention to the prognosis evaluation before the endoscopical therapy.

[Abstract] Objective : :To investigate the long-chain noncoding RNA (Lnc RNA) PCGEM1 regulating the lung cancer (LC) cell invasion and metastasis through the TGF-β/Smad signaling pathways. Methods: :From March 2016 to May 2018, total 62 cases of LC patients receiving surgical treatment in our hospital were collected, including cancer tissues and normal tissues more than 2 cm away from the cancer tissues. qRT-PCR was used to detect the expression of lncRNA PCGEM1 and miR-148a in LC, corresponding para-cancer tissues and different LC cell strains. LncRNA PCGEM1 silenced cell line A549-siPCGEM1 and negative control A549-NC were constructed, and A549 was used as blank control. MTT and plate cloning assay were used to detect the effect of PCGEM1 on the proliferation of A549 cells. Transwell and scratch assay were used to detect the effect of PCGEM1 on the invasion and migration of A549 cells. The bioinformatics website StarBase was used to predict the complementary binding miRNAof PCGEM1. Furthermore, according to the website Targetscan, the genes that the corresponding miRNAs could target and bind were predicted. Results: :qRT-PCR results showed that the expression of PCGEM1 in LC tissues and lung cancer cell lines was higher than that in normal tissues, and the expression level of miR-148a was lower than that in normal tissues (all P<0.05). The expression level of PCGEM1 in A549 cells was the highest, and the difference was statistically significant compared with other cell lines (P<0.05). After successful construction of PCGEM1 silenced cells, compared with the blank control group and A549-NC group, the cell OD492nm value of A549-siPCGEM1 group was significantly decreased, the number of cell clones and the number of matrigel matrix gels was significantly reduced, the cell migration rate was significantly reduced, the differences were statistically significant (P<0.05). According to the prediction results of StarBase website, PCGEM1 could be complementary to miR-148a, and the prediction analysis on microRNA.org website shows that miR-148a had a targeted binding site with TGF-β2. qRT-PCR and Western blotting results showed that the expression of miR-148a was significantly increased in the A549-siPCGEM1 group compared with the blank control group and A549-NC group, and the expression of TGF-β2 and p-Smad 2 was significantly decreased (P<0.05), while the expression of the above indicators in the blank control group and A549-NC group was not statistically significant (P>0.05). Conclusion: :Lnc RNA PCGEM1 is highly expressed in lung cancer. High expression of PCGEM1 may enhance the TGF-β2/Smad2 signaling pathway by downregulation of miR-148a, thus promoting the development of LC and the malignant biological behavior.

OBJECTIVETo study the risk classification of animal plague in Spermophilus Dauricus Focus, using the Best Subsets Regression (BSR) model.
METHODSMatlab, BSR and exponential smoothing were employed to develop and evaluate a model for risk classification as well as to forecast plague epidemics at the Spermophilus Dauricus Focus. Data was based upon the Inner Mongolia surveillance programs. This model involved 7 risk factors, including density of Spermophilus dauricus, percentage of hosts infested, host flea index, percentage of nests infested, nest flea index, percentage of runways infested, and runway flea index.
RESULTSForecasting values of the classification model(CM)were calculated and grouped into 3 risk levels. Values that over 2/3 of the CM would indicate the existence of potential epidemics while those below 1/3 would indicate that there were no risk for epidemics but when values that were in between would indicate that there exist for high risk. Annually, during the observation period in the Inner Mongolia Spermophilus Dauricus Foci, the detection of Yersinia pestis gave a risk rating value of 1 which stood for existing epidemics, while nil detection rate generated a 'zero' value which representing the situation of non-epidemic. The overall plague epidemics forecasting surveillance programs in 2012 at the Spermophilus Dauricus Foci indicated that no active plague was observed. When the forecasting values became over 2/3, combinations of all the risk factors would achieve the consistency rates of 100%. When the forecasting values were below 1/3, combinations of at least the first 4 factors could also achieve the consistency rates of 100%. However, when the forecasting values fell in between, combinations of at least the first 4 factors would achieve the consistency rates of around 50%.
CONCLUSIONResults from our study showed that plague would not be active to become epidemic, in 2012.
