Objective To investigate the association of chromosome 8p copy number alteration (CNA) with postoperative survival of patients with hepatocellular carcinoma (HCC),and to screen for possible target genes in the survival-related CNA (s) in 8p.Methods 187 HCC patients were enrolled into the study,which included 66 patients whose follow-up data were available and the follow-up was 2.6 ～ 73.3 months.High-resolution Agilent 244K comparative genomic hybridization (CGH) and Affymetrix U133 Plus2.0 expression arrays were used to screen for CNAs and gene expression differences in 8p.The associations between CNAs in 8p and survival were analyzed using the log-rank test,Kaplan-Meier survival analysis and Cox proportional hazards models.The gene expression levels between the groups were compared by the Mann-Whitney U test.Results Copy number loss on 8p12 (31/66,47％) was significantly associated with reduced survival rate,and HCC patients with 8p12 loss had a 4.1-fold (95％ CI =1.8 ～ 9.4,P ＜ 0.05) increased hazard ratio (HR) for death from HCC,as compared to those without the loss.The mRNA expression levels of the 3 genes in 8p12,including TMEM66,DCTN6,and MAK16,were significantly decreased in HCCs with gene loss than in HCCs without the loss (all P ＜ 0.05),and in non-tumorous liver tissues (all P ＜ 0.05).Conclusion Loss of 8p12 is an independent prognostic marker of unfavorable survival for patients with HCC,and underexpression of genes TMEM66,DCTN6,and MAK16,owing to 8p12 loss,contributed to unfavorable prognosis.

Objective:To evaluate the CT value in diagnosing the fracture of paranasal sinuses.Methods:The CT and clinical findings of 300 cases with fracture of paranasal sinuses were analysed retrospectively.Results:Of 300 cases,49 cases were fracture of single sinus wall,96 cases were fractures of multiple wall in single sinus and 155 cases were fracture of multiple wall in sinuses."Teardrop sign",accumulatioun of blood at sinus cavity and changes of extraoculer muscles were found.Conclusion:Sinonasal fracture can be diagnosed by CT comprehensively and accurately,that is very important in choosing the treatment methods for sinonasal fracture.

Objective To investigate the clinical value of hemostatic silk in prevention of wound bleeding and wound healing after endoscopic submucosal dissection (ESD). Methods Experiment group: animal model was made by rabbit underwent ESD simulation in its' stomach and laying hemostatic silk on its' wound;control group: animal model was made by pig underwent ESD simulation in its' colon without any healing management. All the ulcers sites were endoscopically and pathologically examined to evaluate the hemorrhage and healing of the wound on 3 days, 1 week, 2 weeks and 4 weeks after the procedure. Results The blood loss in experiment group was significantly lower than that in control group. The wounds of all the experimental pigs underwent colon ESD successfully covered with hemostatic silk postoperatively. Endoscopic pathological examination shown better healing procedure in experiment group. No procedure-related adverse event occurred in both groups. Conclusions Hemostatic silk has potential application value in healing the wound after ESD demonstrated by animal experiment.

Objective To analyze the office blood pressure ( OBP ) and ambulatory blood pressure monitoring (ABPM) among clinical nurses in large hospitals .Methods Totals of 71 clinical nurses from large hospitals of Liaoning provincial were recruited as analysis objects .And 76 female staffs from other institutions took part in the Physical Check-up during the same time were recruited as control group .All the recruited objects received the office blood pressure ( OBP ) and ambulatory blood pressure monitoring ( ABPM ) . Results The prevalence of masked hypertension ( MH) in clinical nurses was higherthan that in control group (14.08%vs 2.63%,χ2 =6.423,P<0.05).The prevalence of white coat hypertension (WCH) in clinical nurses was lower than that in control group (1.41% vs 11.84%,χ2 =4.761,P<0.05).The mean value of OSBP,ODSP of clinical nurses was significantly lower than that of control group [OSBP :(125.35 ±15.14) vs (131.71 ±16.62),t=2.418,P<0.05;ODSP:(76.15 ±9.67) vs (82.94 ±11.25),t=3.907,P<0.05)]. The measured value of 24h-mSBP(127.34 ±13.46) vs (121.09 ±13.73),24h-mDBP(79.47 ±10.36) vs (75.82 ±9.18),dSBP,dDBP,nSBP,nDBP and loading value of dSBP ,dDBP,nSBP,nDBP of clinical nurses were significantly higher than those of control group (t =2.781,2.261,2.918,3.284,2.547,3.544,2.864, 2.561,2.623,2.837,respectively;P <0.05).Conclusions Among clinical nurses from large hospitals, measured value and loading value of ABPM were higher , OBP was lower and MH prevalence was increasing .

Objective To study the treatment of femoral intertrochanteric fractures by reduction without a traction table in a special position and fixation with proximal femoral nail antirotation (PFNA).Methods From May 2016 to May 2017,34 patients with femoral intertrochanteric fracture were treated with PFNA.They were 20 men and 14 women,from 36 to 89 years of age (average,69.9 years).The left side was affected in 15 cases and the right side in 19.By AO classification,there were 10 cases of type AO 31-A1,13 ones of type 31-A2,and 11 ones of type 3 l-A3.Two cases were complicated with other fractures,and 5 with internal system disease,3 of whom had more than 2 concomitant diseases.Preoperative deep venous thrombosis was found in 2 cases.Surgery was performed for them between 2 and 8 days after injury (average,3.7 days).Reduction was performed in a special position without a traction table.The duration of anesthesia,operation time,intraoperative hemorrhage,postoperative complications and hip function by Harris scores were recorded.Results For the 34 patients,the anesthesia time ranged from 57 to 85 min (average,67.5 min),the operation time ranged from 28 to 65 min (average,40.9 min),and the intraoperative hemorrhage from 80 to 150 mL (average,110.6 mL).They received effective follow-up for 6 to 12 months (average,8.4 months).All the fractures healed after 6 to 12 months(average,7.2 months).No failure of internal fixation was observed during follow-ups.By the Harris scores at the final follow-up,the function of the affected hip was rated as excellent in 9 cases,as good in 21 and as fair in 4,giving an excellent to good rate of 88.2％.Conclusion In the treatment of femoral intertrochanteric fractures,reduction without a traction table in a special position and PFNA fixation may reduce anesthesia time,leading to satisfactory clinical outcomes.

Sheep pox is widespread worldwide and is the most severe animal pox virus infection. This study aimed to identify the key microRNAs (miRNAs) differentially expressed in the exosomes of sheep poxvirus-infected cells and their target genes and related pathways and provide a theoretical basis for an in-depth understanding of the molecular mechanisms of sheep poxvirus-infected cells. In this study, the differentially expressed miRNAs were verified by quantitative polymerase chain reaction (qPCR), and the target genes of miRNAs were predicted and analyzed by bioinformatics. The qPCR results showed that the expression trends of oar-miR-21, oar-miR-10b, oar-let-7f, oar-let-7b, and oar-miR-221 were consistent with the sequencing results. The Gene Ontology and Kyoto Encyclopedia of Genes and Genomes results showed that differentially expressed miRNAs were mainly involved in the immune system processes of the Arf6 downstream pathway. The target genes Reactome pathways were mainly enriched in the RAC1 GTPase cycle, CDC42 GTPase cycle, RHO GTPase cycle, RHOV GTPase cycle, and post-transcriptional silencing of small RNAs. The transcription factors SP4, NKX6-1, MEF2A, SP1, EGR1, and POU2F1 that may be connected to sheep pox virus (SPPV)-infected cells were discovered by transcription factor annotation screening. In conclusion, this study screened for differentially expressed miRNAs in SPPV-infected cells and performed a series of bioinformatic analyses of their target genes to provide a theoretical basis for the molecular mechanism of sheep pox virus infections of cells. The data can be used as basic information in future studies on the defense mechanisms against poxvirus infections.
