Purpose To explore the mutation characteristics of common driver genes in non-small cell lung cancer (NSCLC) and its relationship with clinicopathological features.Methods Next generation sequencing (NGS) was used to detect the mutations of common driving genes such as EGFR, KRAS, ALK, ROS1, BRAF, MET, RET and HER-2 in 300 paraffin-embedded NSCLC tissues. Results In 300 patients with NSCLC, the mutation rates of EGFR, KRAS, ALK, ROS1, BRAF, MET, RET, HER-2 were 52.00％, 10.33％, 6.67％, 1.67％, 3.67％, 3.33％, 1.00％, and 2.33％, respectively. A case of EGFR 21 exon L858 R mutation was combined with LINCO1446-EGFR gene fusion. EGFR 20 th exon C797 S and T790 M existed in cis or trans form and merged with EGFR sensitive mutations in 1 case each. 3 cases of EGFR gene point mutation was associated with MET gene copy number amplification. EGFR mutations were more commonly detected in non-smoking women with lung adenocarcinoma (P<0.05).KRAS mutations were more commonly found in smoking men (P<0.05). ALK mutations were associated with age (P<0.05), and more commonly noted in patients younger than 60 years.ROS1 fusion mutations were associated with gender (P<0.05), more commonly detected in women. BRAF, MET, RET, and HER-2 gene mutations were not associated with gender, age, smoking, histological type, and c TNM stage. Conclusion EGFR can coexist with other driver gene mutations. Gene mutations and clinicopathological features like gender, age, smoking, and histological types have corresponding links. The incidence of BRAF, MET, RET, and HER-2 mutations is low, and its clinical significance remains to be explored. Coexisting gene mutations and rare mutations discovered by NGS should be taken seriously.

Objective To evaluate the safety of Propofol combined with Fentanyl in intravenous anesthesia for endoscopic retrograde cholangiopancreatography(ERCP)in elderly patients.Methods The clinical data of 63 elderly patients aged ≥80 years with common bile duct stones who underwent ERCP in digestive endoscopy center of our hospital were retrospectively analyzed.All the patients were divided into Propofol combined with Fentanyl anesthesia group(group A,n =41)and midazolam combined with Fentanyl anesthesia group(group B,n=22).The changes of blood pressure,heart rate and blood oxygen saturation(SpO2),and postoperative complications were compared between the two groups.Results The incidence of hypotension was higher in Propofol combined with Fentanyl anesthesia group than in midazolam combined with Fentanyl anesthesia group(24.4 ％ vs.0.0％,x2=4.683,P =0.030),but the incidence of SpO2 ＜ 90 ％ in midazolam combined with fentanyl anesthesia group was significantly increased(22.7％ vs.0.0％,x2 =7.250,P =0.007).There was no statistically significant difference in the incidence of anesthesia-related complications (39.0％ vs.36.4％,x2 =0.043,P =0.836) and postoperative complications (4.9 ％ vs.4.5 ％,x2 =0.003,P =0.953) between the two groups.Conclusions For elderly patients with common bile duct stones,intravenous anesthesia with Propofol and Fentanyl during ERCP is safe,and blood pressure changes need to be closely monitored.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.

OBJECTIVE: To detect the expression of CRLF2 in bone marrow mononuclear cells from children with newly diagnosed acute lymphoblastic leukemia(ALL) and to explore its clinical significance in pediatric ALL. METHODS: A total of 218 children with newly diagnosed ALL who achieveal the complete remission and had the complete follow-up information were selected, and the expression level of CRLF2 in bone marrow mononuclear cells of these children was detected by real-time fluorescent quantitative PCR, and the significance of CRLF2 expression level in clinical prognosis of ALL children was analyzed by using statistical method. RESULTS: 28 cases in 218 children with complete data showed high expression of CRLF2. The cumulative recurrence rate in the CRLF2 high expression group was significantly higher than that in the low expression group (53.6% vs 12.6%) (P＜0.01). The predicted 5-year recurrence-free survival rate (RFS) of ALL children with CRLF2 high expression was significantly higher than that of low expression group (P＜0.01). There was no significant difference in the predicted 5-year RFS between ALL children with CRLF2 low and high expression in the standard-risk(SR) group (P＞0.05). The predicted 5-year RFS of ALL children with CRLF2 low expression was higher than that of ALL children with CRLF2 high expression in the intermediate-risk (IR) and high-risk (HR) groups. (P＜0.05). Cox analysis showed that CRLF2 high expression is an independent risk factor for the relapse of children with ALL. CONCLUSION The recurrence rate of pediatric ALL with CRLF2 high expression is high, and CRLF2 high expression is an important prognostic factor for high risk of relapse in ALL children with IR and HR. It is necessary to use CRLF2 expression as an indicator of risk stratification in pediatric ALL.

The aim of this paper was to systematically evaluate the toxicity-reducing effect of Tripterygium-licorice in animal experiments,and also to provide evidence for basic research on the toxicity reduction of Tripterygium wilfordii. The PubMed,EMbase,Web of Science,CBM,CNKI and Wan Fang Databases from their establishment to August 31 th,2018 were searched. Two independent reviewers screened the papers,extracted the data,assessed the risk of bias using SYRCLE assessment tool and conducted Meta-analysis with Rev Man 5. 3 software. A total of 10 papers involving 31 studies were finally included,15 studies of which were used for Meta-analysis. Four studies were included for chronic hepatotoxicity animal model. In experimental group( 34 animals),Tripterygium was administered at dose of 0. 09-0. 1 mg·kg-1·d-1,and glycyrrhizic acid was administered at dose of 90-100 mg·kg-1,both for 2 weeks; in control group( 34 animals),glycyrrhizic acid was replaced with equal volume of normal saline. Eleven studies were included for acute hepatotoxicity animal model. In experimental group( 66 animals),glycyrrhizic acid was administered at dose of 75-480 mg·kg-1 for 7 days,then glycyrrhizic acid was stopped,and Tripterygium began to be administered at dose of 0. 6-1. 0 mg·kg-1 per 24 h or 48 h for a total of 1-2 times; in control group( 66 animals),glycyrrhizic acid was replaced with equal volume of normal saline or corresponding solvent. The results of Meta-analysis showed that in both chronic hepatotoxicity animal model and acute hepatotoxicity animal model,the transaminase levels in the experimental group were lower than those in the control group( P < 0. 05). Subgroup analysis of acute hepatotoxicity animal model showed that the transaminase levels in the experimental group were lower than those in the control group for every subgroup except " glycyrrhizic acid 75 mg·kg-1" subgroup. However,in terms of the mean difference( MD) and confidence interval( CI),there was no significant difference in transaminase decline between each subgroup. Low dose of glycyrrhizic acid( 90-100 mg·kg-1) has a toxicity-reduction effect on chronic hepatotoxicity induced by tripterygium( 0. 09-0. 10 mg·kg-1). Middle and high doses of glycyrrhizic acid( 120-480 mg·kg-1) have a toxicity-reduction effect on acute hepatotoxicity induced by tripterygium( 0. 6-1. 0 mg·kg-1),but with no significant dose-effect relationship.

OBJECTIVE: To investigate the prognostic evaluation value of fluorodeoxyglucose (FDG) interim positron emission tomography/computed tomography (PET/CT) for diffuse large B cell lymphoma (DLBCL). METHODS: Two hundred and twenty-seven patients with pathologically diagnosed DLBCL underwent 18F-FDG scans at baseline and before 3 cycles of a rituximab-containing chemotherapy regimen. The Visual Deauville score (DS) and changes in maximum standard uptake values (ΔSUVmax) were calculated for tracer for the predominant lesion of each patient, for prediction of progression-free survival (PFS) and overall survival (OS) using Kaplan-Meier method and COX regression. RESULTS: The median follow-up period was 71 months. Receiver operating characteristic analysis indicated that the best ΔSUV cut-off values for FDG (ΔSUVFDG) was 71%. The sensitivity, specificity and accuracy of DS and ΔSUVmax were 86.9%, 74.3%, 82.8% and 77.8%, 63.5%, 73.1%, respectively in response assessment. Kaplan-Meier analysis showed DS, ΔSUVmax and IPI had significance for prediction of PFS and OS (P = 0.001). The DS 4-5 and IPI 3-5 were independent risk factors of poor prognosis by COX regression analysis. CONCLUSION Interim PET/CT is important predictor for evaluation therapeutic response and prognosis in DLBCL patients.

OBJECTIVE: To study the expression of SOX4 gene in patients with acute myeloid leukemia (AML) and its correlation with clinical features and prognosis, and to explore the role of this gene in acute myeloid leukemia. METHODS: The real-time guantitative PCR was used to detect the expression level of SOX4 gene in bone marrow of 96 patients with newby diagmsed AML, and the features and prognosis was analyzed. RESULTS: The level of SOX4 expression in the 96 AML patients was significantly higher than that in healthy controls (P<0.01), and the expression of SOX4 gene was not significanly different between M1-M5 (P<0.05). The expression of SOX4 gene was no significanly different between different sex, nationality, and remission after chemotherapy (P>0.05). In AML patients the SOX4 gene expression level did not significantly correlated with the white blood cell count, hemoglobin level, platelet count primitive cell count, reticulocyte count and other laboratory indexes ( P>0.05), while which correlated with the overall survival (OS) (P<0.01) and erent-free survival (EFS) (P<0.05). CONCLUSION The high expression of SOX4 gene affects the survival time of patients (OS, EFS), suggesting that may be one of the unfavorable prognostic factors for the AML patients.
