Objective To study the characteristics of microscopic spread of esophageal squamous-cell carcinoma (ESCC) and the influence of clinicopathological features on it to help define the clinical target volume (CTV) margin in radiotherapy.Methods Sixty-four surgical specimens of ESCC were observed for longitudinal microscopic spread per centimeter both proximally and distally from the tumor.The shrinkage ratio of each specimen was calculated and used for tissue incision.Results The further the distance beyond the tumor, the lower the incidence there was of microscopic spread.Positive rates of microscopic spread in group 3 cm of proximal and distal were 4.8% and 6.9%, respectively, and in group 4 cm were both 3.6%.Tumors longer than 5 cm in length,with poorer differentiation, lymph nodes metastasis and more aggressive phase had higher positive rates (79.3% vs 45.7%,77.4% vs 45.5%,76.0% vs 51.2%,70.5% vs 40.0%,χ2=7.52,6.86,3.91,5.36;P=0.006,0.009,0.042,0.021).Differentiation and tumor length were main factors contributing to microscopic spread (χ2=0.19,4.82;P=0.020,0.017).Conclusions To cover 95% of the microscopic spread,a margin of 3.0 cm proximal and 4.0 cm distal beyond gross tumor volume is needed and as to 90%, a margin of 3.0 cm both proximal and distal is needed.Moreover, the influence of pathological features should be taken into account.

Objective To learn the current capacity building of emergency response teams in Tianjin for the purpose of goals setting.Methods Health Emergency Capacity Questionnaire was issued to 89 secondary and above medical institutions and 19 CDCs in Tianjin.The form covered such items as basic institutional information, workforce makeup, emergency preparations, detection and early warning, emergency response, and summary/assessment.Data collected in the questionnaire were subject to descriptive and correlation analysis.Results Tianjin has scored an initial success in emergency medicine as evidenced in its emergency response mechanisms in place, elevated capacity in emergency medical rescue and disposal, and enhanced competence of emergency teams.Rooms of improvement however include insufficient professionalism and independence of health emergency, inadequate emergency commanding and decision making system functions, insufficient laboratory test capacity at district/county levels, and insufficient social involvement in health emergency.Conclusions Top-down design should be emphasized, health emergency response should be enhanced in terms of management and response planning system, while capacity building of the teams and long-term primary care emergency mechanism deserve higher attention.

Objective This study aims to analyze midterm survival and to assess the midterm mortality following acute kidney failure (AKF) of patients undergoing surgical treatment of acute type A aortic dissection.Methods Clinical data of the patients who underwent Sun's procedure from February 2009 to March 2015 were collected.Patients with preoperative dialysis were excluded.Data including preoperative cardiovascular diseases,serum creatinine leve1 and CPB time were gathered.The patients were divided into the group of AKF and the group of non-AKF accounting to require dialysis.The group of AKF was follow-up by phone.Midterm mortality was studied with Cox analysis and midterm survival was estimated by Kaplan-Meier analysis.Results 524 patients underwent aortic surgeries which AKF was occurred in 51 (51/524,9.7％) patients.Hospital mortality was 23.5％ (12/51) in AKF group which seven death were strokes,three death were lower-extremity ischemia and two death were low cardio output.There were 2 patients dead with multi organ failure and paraplegia in first year.One reoperation patient because of anastomotic fistula was dead in fifth year.Only diabetes was independently associated with midterm mortality.Midterm survival for patients with AKF was 56％ during a median follow-up of 30.5 months.Survival was equal between the subgroups of Cr ＞ 200 mol/L and Cr ＜ 200 mol/L(P =0.741).Conclusion AKF after acute aortic dissection was a severe complication and the incidence was 9.7％.In patients with AKF,diabetes was associated with increased mortality across follow-up.Five years survival was 56％ not effected by preoperative Cr.

Mitochondrial fission regulator 2 (MTFR2) is associated with mitochondrial fission, while few studies have assessed the associations between MTFR2 expression and clinical characteristics or prognosis of esophageal squamous cell carcinoma (ESCC). In this study, we compared the expression of MTFR2 in 6 ESCC tumors and relative normal tissues by immunohistochemistry (IHC). To assess the effect of MTFR2 expression on clinicopathologic characteristics and survival, 115 paraffin embedded ESCC tissue samples were assessed by IHC staining. Furthermore, the association between clinicopathological properties and MTFR2 expression in patients with ESCC was examined. The survival analysis was performed using the Cox regression models. We found that MTFR2 expression was significantly increased in ESCC tumors compared with normal esophageal epithelial cells. IHC analysis of 115 paraffin embedded ESCC tumor specimens of the patients showed that the expression of MTFR2 was significantly associated with clinical stage (P < 0.001), tumor classification (P < 0.001), histological grade (P < 0.001), and other clinicopathological characteristics. Both univariate and multivariate analyses showed that MTFR2 expression was inversely correlated with the survival of ESCC patients. In conclusion, the expression of MTFR2 is significantly associated with clinicopathologic characteristics and prognosis of ESCC. Thus, MTFR2 expression could serve as a potentially important prognostic biomarker and clinical target for patients with ESCC.

Klebsiella pneumoniae is one of the common pathogens causing hospital-acquired infection. With the wide use of carbapenem in recent years, carbapenem-resistant Klebsiella pneumoniae (CRKP) has emerged around the world. Carbapenemase production is the main cause of resistance to carbapenem antibiotics in Klebsiella pneumoniae. More than 70% of Klebsiella pneumoniae strains produce carbapenemase. Ceftazidime/avibactam (CAZ/AVI) can effectively treat CRKP infection, especially those caused by CRKP that can produce Klebsiella pneumoniae carbapenemase (KPC) or oxaclillinase (OXA)-48. However, it has been reported that CAZ/AVI-resistant CRKP strains have emerged. In this paper, the epidemiology, risk factors, resistance mechanism and treatment of CAZ/AVI-resistant CRKP were summarized to provide reference for clinical treatment.

OBJECTIVETo explore the differential characteristics of the AMA-M2 autoantibody in patients with primary biliary cirrhosis (PBC) and non-PBC patients.

METHODSPatients with abnormal liver function at the Capital Medical University affiliated to Beijing You-an Hospital were enrolled in this study between January 2011 and December 2013. Serum levels of ANA, AMA and AMA-M2 were detected by indirect fluorescence assay and enzyme-linked immunosorbent assay. The patients' clinical data was obtained for retrospective analysis. Statistical analyses were performed using the SPSS 16.0 software. Enumeration data have been presented as numbers and percentages, and were analyzed using the chi-square test and one-way ANOVA test.

RESULTSOf the 5315 patients with abnormal liver function, 15.3% (811/5315) were AMA-M2 positive patients; among those 811 patients, 78.4% (636) had PBC, 4.4% (36) had PBC overlapping with autoimmune hepatitis (AIH), 4.4% (36) had drug-induced liver injury, 6.5% (53) had hepatitis B, 3.3% (27) had hepatitis C, 0.6% (5) had hepatitis E, 0.9% (7) had alcoholic liver disease, 0.5% (4) had non-alcoholic fatty liver, 0.8% (6) had primary hepatic carcinoma, and 0.1% (1) had infectious mononucleosis. Serum AMA-M2 level was significantly higher in the PBC patients (vs. other groups, P less than 0.001) with the exception of the patients with PBC/AIH overlap syndrome. Among the 811 patients with AMA-M2 positivity, 88.5% (718) showed AMA positivity and 91.1% (739) showed ANA positivity. Serum alanine transferase (ALT) and aspartate transferase (AST) levels were significantly higher in the drag-induced liver injury patients (527.74+/-684.65 U/L, 490.60+/-716.89 U/L) and the hepatitis E patients (1015.94 ± 165.55 U/L, 665.4 ± 297.14 U/L) than in the PBC patients (96.02 ± 115.56 U/L, 94.82 ± 83.32 U/L) (ALT: F =8.041, P < 0.001, P < 0.001; AST: F =8.066, P < 0.001, P < 0.001). Serum alkaline phosphatase (ALP; 265.16 ± 179.08 U/L) and glutamyl transferase (GGT; 332.02 ± 279.29 U/L) were significantly higher in the PBC patients than in the hepatitis B patients (135.35 ± 123.17 U/L, 140.27 ± 229.24 U/L) and the hepatitis C patients (85.65 ± 27.77 U/L, 92.70 ± 125.72 U/L) (ALP: F=3.911, P =0.01, P=0.001; GGT: F=4.081, P <0.001, P < 0.001). The serum IgM level was significantly higher in the PBC patients (4.60 ± 2.67 g/L) than in the patients with drug-induced liver injury (1.76 ± 1.15 g/L), hepatitis B (2.02 ± 1.41 g/L), hepatitis C (1.48 ± 0.92 g/L), hepatitis E (1.40 ± 0.68 g/L), alcoholic liver disease (1.57 ± 1.07 g/L), non-alcoholic fatty liver (1.05 ± 0.72 g/L), and primary hepatic carcinoma (2.64 ± 2.26 g/L) (F=16.83, P < 0.001, P < 0.001, Probability value < 0.001, Probability value < 0.05, Probability value < 0.01, Probability value < 0.05 respectively).

CONCLUSIONAlthough detection of serum AMA-M2 is an important feature of PBC diagnostic testing,there is a high ratio of serum AMA-M2 detected in patients with drug-induced liver injury, hepatitis B, C and E, alcoholic liver disease, non-alcoholic fatty liver,and primary hepatic carcinoma. The AMA-M2 positive non-PBC patients still require close observation to watch for future development of PBC.
