Objective To discuss the safety and short-term efficacy of MR-guided focused ultrasound surgery (MRgFUS) for pain palliation of bone metastases patients.Methods Fourteen patients with painful bone metastases were recruited in this prospective study.The treating efficacy was characterized by numerical rating scale (NRS),the brief pain inventory quality of life (BPI-QOL) survey,and Karnosky performance status scale (KPS).Adverse events occurred pre-and post-treatment were analyzed.Normal distributed statistics was analyzed by using paired-samples t test or Wilcoxon rank sum test.Results Fourteen patients were treated with MRgFUS,2 patients dropped out of the study.The NRS ratings are 6.50(4.00),5.00 (5.25),2.50(5.00),2.50(4.75),2.00 (6.00) for pre-treatment,one week,one month,two months,and three months,respectively.Such variances of NRS ratings were statistically significant (Z=-2.773,-2.740,-2.769,-2.675;P＜0.05).The BPI-QOL ratings were (42.42± 8.27),(30.67 ± 12.29),(29.17±15.38),(29.92± 17.67) and (35.67± 19.28),respectively.The BPI-QOL ratings decreased in the first two months after the treatment which is statistically significant (t=3.231,2.820 and 2.453;P＜0.05);whereas for the third month,the BPI-QOL rating was statistically insignificant compared with the one before the treatment (P＞0.05).The KPS ratings were 80(28),80(20),65(45) for pre-treatment,one week and three months after treatment,respectively.Three months after the treatment,the KPS ratings decreased which was statistically significant compared with the one before the treatment (Z=-2.204,P＜0.05).After the treatment,one patient developed deep venous thrombosis,three patients reported lower extremities numbness,two patients had soft tissue edema around the lesions.Conclusions MRgFUS is effective for short-term pain palliation of bone metastases.Such noninvasive technique is safe and can improve patients' living condition.

Objective:To investigate the value of programmed death-1（PD-1） expression on the T lymphocytes for the prognosis of septic patients.Methods:From September 2017 to May 2019, septic patients were included in Department of Intensive Care Unit at 6 hospitals. The PD-1 expression on T cells were measured by flow cytometry. Logistic regression was conducted to analyze independent risk factors related to death within 28 days，and receiver operating characteristic curve(ROC) was conducted to evaluate the prognostic value of PD-1 expression on T cells in septic patients.Results:A total of 64 septic patients were enrolled to this study，including 32 survivors and 32 deaths. The PD-1 expression on T cells in the death group was significantly higher than that in the surviving group ( P<0.05). Correlation analysis showed that the percentages of PD-1 +/CD3 +T cells and PD-1 +/CD8 +T cells were positively correlated with procalciton in ( r=0.313, P =0.015； r=0.375, P=0.003), logistic regression analysis showed that the percentages of PD-1 +/CD3 +，PD-1 +/CD4 +，PD-1 +/CD8 +T cells were independent risk factors for the death of sepsis patients. The percentage of PD-1 +/CD3 +T cell was 3.63%, with AUC 0.842, sensitivity to predict the mortality 96.43% and specificity 59.38%, ( P<0.000 1). The percentage of PD-1 +/CD4 +T cell was 4.65%, with AUC 0.847, sensitivity 96.43%, specificity 62.50%，( P<0.000 1). The percentage of PD-1 +/CD8 +T cell was 3.91%, with AUC 0.771, sensitivity 64.29%, specificity 81.25%，( P=0.000 3). Conclusions:The T cell PD-1 expression is an independent risk factor to predict the 28-day mortality in septic patients. Combining the proportions of PD-1 +/CD3 +, PD-1 +/CD4 +and PD-1 +/CD8 +T cells may further enhance the predictive value for death.

Objective:To identify the Key genes in the development of sepsis through weighted gene co-expression network analysis (WGCNA).Methods:The gene expression dataset GSE154918 was downloaded from the public database Gene Expression Omnibus (GEO) database, which containes data from 105 microarrays of 40 control cases, 12 cases of asymptomatic infection, 39 cases of sepsis, and 14 cases of follow-up sepsis. The R software was used to screen out differentially expressed genes (DEG) in sepsis, and the distributed access view integrated database (DAVID), search tool for retrieval of interacting neighbouring genes (STRING) and visualization software Cytoscape were used to perform gene function and pathway enrichment analysis, Protein-protein interaction (PPI) network analysis and key gene analysis to screen out the key genes in the development of sepsis.Results:Forty-six candidate genes were obtained by WGCNA and combined with DEG expression analysis, and these 46 genes were analyzed by gene ontology (GO) and Kyoto City Encyclopedia of Genes and Genomes (KEGG) pathway enrichment to obtain gene functions and involved signaling pathways. The PPI network was further constructed using the STRING database, and 5 key genes were selected by the PPI network visualization software Cytoscape, including the mast cell expressed membrane protein 1 gene (MCEMP1), the S100 calcium-binding protein A12 gene (S100A12), the adipokine resistance factor gene (RETN), the c-type lectin structural domain family 4 member gene (CLEC4D), and peroxisome proliferator-activated receptor gene (PPARG), and differential expression analysis of each of these 5 genes showed that the expression levels of the above 5 genes were significantly upregulated in sepsis patients compared with healthy controls.Conclusion:In this study, 5 key genes related to sepsis were screened by constructing WGCNA method, which may be potential candidate targets related to sepsis diagnosis and treatment.

Objective:To study on the effects of gastrointestinal function and portal vein hemodynamics applicated with abdominal hot compressing with evodiae fructus and crude salt after hepatectomy.Methods:A total of 60 patients who underwent hepatectomy were randomly divided into 2 groups by random number table method, with 30 in each group. The control group was treated with conventional basic western medicine, while the treatment group was treated with medicinal evodiae fructus and crude salt hot compress on abdomen on the basis of the control group. The portal vein diameter (PVD), portal venous flow velocity (PVV), recovery time of main clinical indexes, clinical symptom scores and liver function indexes were dynamically monitored at different observation time points.Results:The scores of abdominal distension, nausea and vomiting in the treatment group were significantly lower than those in the control group 3 days after treatment ( t values were -3.489 and -2.740, respectively, all Ps<0.05). The recovery time of bowel sounds, first exhaust time and first defecation time in the treatment group were significantly earlier than those in the control group ( t values were -3.622, -4.297 and -4.151, respectively, all Ps<0.01). With the extension of treatment time, ALT in 2 groups showed a gradual downward trend ( P<0.05 or P<0.01), DBIL in control group was significantly higher at 3 days after treatment than before ( t=-2.157, P=0.039), and TBIL was significantly lower at 7 days after treatment than before ( t=2.175, P=0.038). The PVD ( t values were 3.528, 2.160) and PVV ( t values were 11.096, 4.264) of the treatment group were significantly higher than those of the control group 3 and 5 days after treatment ( P<0.01 or P<0.05). Conclusion:Early application of abdominal hot compressing with evodiae fructus and crude salt hot compress on abdomen after hepatectomy can improve the portal vein blood circulation and promote the rehabilitation of gastrointestinal function in patients with hepatectomy.
