Objective To investigate the clinical efficacy of atorvastafin intensive treatment before percutaneous coronary intervention (PCI) in patients with acute coronary syndrome (ACS) and its affects on serum interleukin (IL)-6 and IL-8.Methods Sixty ACS patients were divided into observation group and control group according to different treatment with 30 cases each.Control group received conventional therapy,while observation group was added with atorvastafin intensive treatment before PCI on the basis of conventional therapy.The serum IL-6 and IL-8 levels were detected before PCI at 24 h,3 d and 6 months after surgery,and the occurrence of cardiac adverse events were observed within 30 days after surgery.Results The serum IL-6 and IL-8 levels between observation group and control group had no statistical differences before surgery (P＞ 0.05).The serum IL-6 and IL-8 levels of observation group were significantly lower than those of control group at 24 h,3 d and 6 months after surgery,respeclively [ IL-6:( 11.56 ± 4.95 )ng/L vs.(20.24 ± 8.67) ng/L,(8.51 ± 3.65) ng/L vs.( 18.83 ± 8.07 ) ng/L,(5.60 ± 2.40) ng/L vs.( 10.02 ±4.29) ng/L;IL-8:(50.34 ± 21.57) ng/L vs.(74.50 ± 31.93) ng/L,(30.80 ± 13.20) ng/L vs.(53.30 ± 22.84)ng/L,( 26.00 ± 11.14 ) ng/L vs.( 40.61 ± 17.40 ) ng/L ] ( P ＜ 0.05 ).There was no cardiac adverse event in observation group within 30 days after surgery.There was 1 case who occurred angina pectoris at 16 days after PCI in control group,and the syrnptoms disappeared after emergency treatment.Conclusions The atorvastatin intensive treatment before PCI can effectively decrease the levels of IL-6 and IL-8 in ACS patients and has the effects of anti-inflammatory and protecting myocardium from damage.

Objective:To discuss the role of incision for short-term outcomes of simultaneous resection in synchronous colorec-tal liver metastases (sCRLM). Methods:We reviewed the data of 37 patients who underwent simultaneous resection between January 2009 and December 2014 in our department and compared the short-term outcomes between Mercedes and midline incisions. Results:Mercedes and midline incisions were used in 19 and 18 patients, respectively. The two groups showed similarities in patient characteris-tics, major hepatectomy, surgery time, blood loss, and hilar block time. The midline group comprised more rectal cancer patients (P<0.001). The two groups did not differ significantly in complication incidence (47.4%vs. 16.7%, P=0.08) and postoperative stay time (22.1 ± 9.5 d vs. 17.2 ± 6.7 d, P=0.08). At body mass index (BMI)<25, the complication incidence (P=0.046) and postoperative stay time (P=0.051) were lower in the midline group than in the Mercedes group. Conclusion:Midline incision provided similar exposure in simultaneous resection for sCRLM and was better than Mercedes incision in rectal cancer patients. Patients with midline incision may attain better short-term outcomes if BMI is<25.

Objective To investigate the copy number changes of A20 and TNF genes,and determine the contribution of the two genes in the development of ocular adnexal MALT lymphoma.Methods Forty-one cases of archive paraffin-embedded ocular adnexal MALT lymphoma tissues were detected by interphase fluorescence in situ hybridization (FISH) using the commercial chromosome 6 centromere probe (CEP6),and house-made site-specific probe of A20 and TNF. Results Of the 41 ocular adnexal MALT lymphoma cases,loss of heterozygosity (LOH)in A20 locus was detected in 2 cases (4.88 ％).TNF extra copies were found in 5 cases (12.20 ％),of which three cases simultaneously had extra CEP6 signals.No A20 deletion were found coexistence with TNF extra copies in any case.Conclusion A20 gene deletion is present in the small part of ocular adnexal MALT lymphoma, and might contribute to the development of Chinese ocular adnexal MALT lymphoma.A20 deletion is not associated with extra copies of TNF locus.

Objective To investigate the safety and effectiveness of endoscopic submucosal dissection(ESD)for elderly patients(≥60 years old)with colorectal lesions.Methods Data of 31 elderly patients(≥60 years old)and 23 non-elderly(<60 years old)patients who were found to have colorectal mucosal lesions by colonoscopy and underwent ESD treatment between January 2012 to January 2014 were retrospectively studied.Results There were no statistical differences between the two groups in gender, concomitant diseases,lesion location,lesion size and postoperative pathological diagnosis (P >0.05 ). Thirty-two lesions in elderly group and twenty-five lesions in non-elderly group were all curative resection.En bloc resection rates were 96.9%(31 /32)and 96.0%(24 /25)in the elderly group and non-elderly group respectively;the rates of bleeding during ESD procedure were 3.2%(1 /31 )and 4.3%(1 /23);delayed bleeding rates were 12.9%(4 /31)and 13.0%(3 /23);the rates of perforation was 12.9%(4 /31)and 0;postoperative infection rates were 3.2%(1 /31)and 4.3%(1 /23)respectively.There were no statistical differences between the two groups in any of these data (P >0.05 ).The mean time of follow-up were (14.8 ±1.7)months in elderly group and (14.7 ±1.8)months in non-elderly group,and there was no significant difference between two groups.No residual lesion or recurrent lesion was found in the follow-up period.Conclusion ESD is a safe and effective treatment for the elderly patients with colorectal lesion.

OBJECTIVE The purpose of this study was to analyze the screened miRNAs related to tumorigenesis using miRNA array in laryngeal squamous cell carcinoma (LSCC), and provide a set of miRNAs that may be useful for the development of novel diagnostic markers and/or more effective therapeutic strategies from the screened miRNAs in LSCC. METHODS A total number of 5 patients who underwent surgery for primary laryngeal squamous cell carcinoma were recruited for miRNA array analysis. LSCC tissues compared with corresponding adjacent non-neoplastic tissues were analyzed by the Affymetrix GeneChip miRNA Array 3.0 to screen effective miRNAs, and the raw dataset had been submitted to Gene Expression Omnibus. Then mirfocus 3.0 database was adopted to analyze putative regulated miRNAs related to MCM4, a gene related to tumorigenesis we had studied previously in LSCC. Moreover, the selected putative regulated miRNAs were also validated by qRT-PCR in another 21 patients diagnosed as LSCC. RESULTS Analyzed by the miRNAs arrays, there were 127 miRNAs significantly related to tumorigenesis, and 78 showed a higher expression in tumor than in non-tumor tissue while 49 presented the contrasting pattern (P<0.01). Then analyzed by mirfocus 3.0 database, there were 2 putative regulated miRNAs, hsa-miR-24-3p and hsa-miR-183-5p, related to the expression of MCM4. Another miRNA we should focus on was hsa-miR-30a-5p, which was down-expressed obviously analyzed by the miRNA array. The expression of the 3 putative regulated miRNAs were also validated by qRT-PCR in another 21 patients, and the result was the same with that in miRNA array (P<0.05). CONCLUSION The 3 putative miRNAs based on miRNA array analysis, hsa-miR-24-3p, hsa-miR-183-5p and hsa-miR-30a-5p, could be considered as potential diagnostic and therapeutic markers in LSCC. The result will contribute to the understanding of the molecular basis of LSCC and help to improve the treatment.

Background The management of Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) is controversial due to the early recurrence after curative hepatectomy,and many variables were related to the prognosis.The purpose of this study was to predict the tumor recurrence in early postoperative period of the patients with BCLC stage B HCC.Methods From January 2004 to January 2012,104 patients with BCLC stage B HCC underwent hepatectomy.Clinicopathological factors and follow-up data were statistically analyzed to establish a predicting scoring system.Results The overall survival rates for one,three,and five years were 69.2％,52.7％,and 42.3％,and the disease-free survival rates for one,three,and five years were 52.9％,47.3％,and 37.5％,respectively.The multiple factors analysis showed that the micro-vessel invasion,lymph nodes metastasis,multiple lesions,and the high expression of HMGB1 were independent factors (P ＜0.05).A scoring system was established to predict the early recurrence within one year after the surgery for BCLC stage B HCC,according to the analysis results with a specificity of 85.1％ and a sensitivity of 80.3％.Conclusion Variant clinicopathological factors were associated with early postoperative recurrence for BCLC stage B HCC and recurrence early after hepatectomy was more likely in patients with a higher score of the scoring system.

Objective To explore the clinical value of uncinate process resection combined with portalsuperior mesenteric vein resection and end-to-end anastomosis in distal pancreatectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 11 patients who underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis in the Peking University Cancer Hospital (8 patients) and Jilin Guowen Hospital (3 patients) between January 2014 to April 2018 were collected.During the vascular reconstruction,uncinate process of the pancreas was first resected for reducing anastomotic tension,and then end-to-end anastomosis was done after portal-superior mesenteric vein resection.Observation indicators:(1) intraoperative situations;(2) postoperative recovery situations;(3) postoperative pathological examination situations;(4) follow-up and survival situations.Follow-up using outpatient examination and imaging examination was performed to detect patients' postoperative survival,tumor recurrence and metastasis and postoperative venous anastomotic patency up to May 2018.Measurement data with normal distribution were represented as x±s.Measurement data with skewed distribution were described as M (range).The non-recurrence and non-metastasis survival curve,overall survival curve and survival rate were respectively drawn and calculated by the Kaplan-Meier method.Results (1) Intraoperative situations:11 patients received uncinate process resection of the pancreas,and successfully underwent distal pancreatectomy combined with portal-superior mesenteric vein resection and end-to-end anastomosis.Eight patients underwent distal pancreatectomy + Appleby combined with celiac axis resection due to pancreatic tumor involving common hepatic artery,including 2 undergoing combined total gastrectomy due to gastric ischemia;2 patients underwent distal pancreatectomy;1 patient underwent distal pancreatectomy + distal gastrectomy due to blood supply obstacle of distal stomach.Operation time and volume of intraoperative blood loss of 11 patients were (5.8± 1.1) hours and 800 mL (range,200-2 500 mL).(2) Postoperative recovery situations:there was no grade C of pancreatic fistula of 11 patients.Four patients had grade B of pancreatic fistula,including 2 were cured by drainage-tube indwelling of pancreatic wound ＞ 3 weeks,1 was cured by continous washing due to pancreatic fistula combined with infection,and 1 was cured by the second abdominal puncture drainage due to pancreatic fistula with fever;1 of 4 patients was combined with grade C of delayed gastric emptying and cured by conservative treatment,and other 3 patients didn't occur postoperative complications.Of 5 patients diagnosed as biochemical fistula,1 had esophagus-jejunum anastomotic leakage,and 1 had changes of hepatic ischemia in S2,S3 and S4b segments by CT examination and recovered normal liver function at 2 weeks postoperatively,with long-term hepatatrophia in S2 and S3 segments.There was no postoperative death and reoperation in 11 patients.Duration of postoperative hospital stay of 11 patients was (22± 5) days.(3) Postoperative pathological examination results:tumors of 11 patients were located in neck and body of the pancreas,with a maximum diameter of (4.8± 1.7)cm.Among 11 patients,10 were confirmed with moderate-or low-differentiated ductal adenocarcinoma and 1 with anaplastic carcinoma.The length of portal-superior mesenteric vein resection of 11 patients was (2.6± 0.8) cm.Seven of 11 patients occurred different degrees of tumor infiltration in the portal-superior mesenteric vein,and other 4 patients occurred inflammatory adhesion,without tumor infiltration.(4) Follow-up and survival situations:11 patients were followed up for 3.0-37.6 months,with a median time of 15.7 months.During the follow-up,8 patients died of tumor recurrence and /or metastasis,and 3 survived;the non-recurrence and non-metastais survival time and overall survival time were respectively 9.0 months (range,3.0-37.6 months) and 24.6 months (range,3.0-37.6 months).One patient was complicated with anastomotic stenosis and surrounding varices of portal-superior mesenteric vein by postoperative half-year reexamination,anastomotic vein anomalies and venous thrombosis were not found in other patients before local tumor recurrence and / or death.Conclusion The combined uncinate process resection of the pancreas cannot increase the risk of postoperative pancreatic fistula,and it could effectively reduce the anastomotic tension in the distal pancreatectomy combined with portal-superior mesenteric vein resection and reconstruction,meanwhile,it can also achieve end-to-end anastomosis after longer vein resection.

Objective To analyze the differentially expressed genes produced by paclitaxel,cisplatin and 5-fluorouracil(TPF) regimen induction chemotherapy and the potentially functionally targeted genes of the induc ed chemotherapy in supraglottic laryngeal squamous cell carcinoma.Methods A total of 11 tissue samples from patients diagnosed as supraglottic carcinoma who didnt receive any treatment before were analyzed with microarray.The patients were divided into two groups based on their responses to the induction chemotherapy:7 were sensitive to chemotherapy and 4 were non-sensitive.Gene expressions were detected by Illumina Human HT-12 BeadChip.The bioinformatics analysis online was used to analyze the differentially expressed genes.Results A total of 1 554 differentially expressed genes related to chemosensitivity were found.Analyzed with GO database,the up-regulated genes included the functional sets of biological adhesion,immune system development and stem cell proliferation,and the down-regulated genes included the functional sets of cell junction organization,phosphorus metabolic process and cell morphogenesis involved in differentiation.Analyzed with KEGG database,the up-regulated pathways included p53,cell adhesion and Ras signaling pathways,and the down-regulated pathways included focal adhesion,endocytosis and ErbB signaling pathways.There were statistically significant differences in the expressions of MAPK10,PIK3R5 and JUN genes,which had biological significance,between sensitive patients and non-sensitive patients.Conclusion MAPK10,PIK3R5 and JUN may be considered as potentially functional genes of the induced chemotherapy in supraglottic carcinoma.
