Objective To explore the relation between clinical-pathological features,Siewert classification and prognosis of esophagogastric junction (EGJ) carcinoma,and to assess the applicability of the new edition of American Joint Committee of Cancer (AJCC) staging guideline on EGJ adenocarcinoma in China.Methods From 2002 to 2012,the clinical data,pathological features,treatment and prognosis of 218 patients with EGJ malignant tumor were retrospectively analyzed.The patients were typed according to Siewert classification criteria and each case was staged according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma and gastric cancer.Kaplan-Meier method and Log-rank test were performed for survival analysis.Results According to the Siewert classification,type Ⅰ was rare (nine cases,4.1％),type Ⅱ was the most common type (150 cases,68.8％) and followed by type Ⅲ (59 cases,27.1％).There was no significant difference in survival curve among the three types (P＞0.05).The survival curve was drawn according to 7th edition of AJCC TNM staging criteria for esophagus adenocarcinoma.In T staging,the prognosis of patients at T4b was better than that of patients at T4a,the prognosis of patients at ⅡB was better than that of patients at ⅡA.The survival curve of patients at Ⅲ C obviously crossed with that of patients at Ⅳ,which was not in conformity with clinical results.The survival curve was drawn according to 7th edition of AJCC staging criteria for gastric cancer.In T staging,the survival curve of patients at Tis was overlapped with that of patients at T1a.The survival rate of patients at ⅡB could not be accurately predicted by the overall staging.In general,the survival of patients with EGJ carcinoma was better predicted according to 7th edition of AJCC staging criteria for gastric cancer than 7th edition for esophagus adenocarcinoma.Conclusions Neither 7th edition of AJCC staging criteria for esophagus adenocarcinoma nor for gastric cancer could accurately predict its prognosis.In our country,EGJ malignant tumor was similar to gastric cancer and had specific clinical-pathological features.It is necessary to research and establish EGJ carcinoma staging criteria instead of applying the current staging criteria for esophagus adenocarcinoma or gastric cancer.

Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9％) located in the neck segment of esophagus, 119 lesions (14.0％) located in the upper segment, 44 lesions (5.2 ％) located in the upper-middle segment, 409 lesions (48.1％) located in the middle segment, 123 lesions (14.5 ％) located in the middle-lower segment, 122 lesions (14.4％) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1％), followed by medulla type (260 cases, 35.9％), fungating type (80 cases, 11.0％) and constrictive type (70 cases, 9.7％), and the least cases were intraluminal type (nine cases, 1.2％).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 ％) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2％), and the least common cytological type was adenocarcinoma (seven cases, 0.8 ％).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1％), six (0.8％), 271 (37.4％), 278 (38.4％) and 161 (22.2％), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 ％), the others cases were adenocarcinoma (three cases, 2.5 ％), small cell carcinoma (three cases, 2.5 ％), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8％).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.

In order to evaluate the applied value of soluble intracellular adhesion molecule-1 (sICAM-1) in acute rejection (AR) following liver transplantation, the expression of sICAM-1 protein was sequentially detected by using ELISA in serum and bile of 43 patients receiving liver transplantation. In AR group, the expression levels of sICAM-1 protein were increased 3 days before and immediately on the establishment of AR diagnosis, and there was significant difference in the expression of bile between AR group and control group (P<0.01). After reversion of AR with hormone intensive therapy, there was significant difference in the sICAM-1 protein expression of serum and bile between AR group and control group. It was concluded that the sequential detection of sICAM-1 protein level in serum and bile was a reliable and noninvasive method for the early diagnosis of AR after liver transplantation and was valuable to observe the curative effects of anti-AR therapy.

Objective To form a concise and useful warning scale of suicide ideation of inpatients with somatic disease.Methods 2 677 inpatients who were more than 15 years old were randomly selected in a comprehensive hospital during the period of 2010.11-2013.02.Self-rating Depression Scale (SDS),Self-rating Anxiety Scale(SAS) and self-designed questionnaires which included general information,suicide risk factors and somatic disease were applied.Chi square test,partial correlation analysis,t test,correlation analysis and ROC curve analysis were used for statistical analysis.Results 1.The warning scale of suicide ideation which contained 18 items was formed.2.The Cronbach's Alpha reliability of the warning scale was 0.84 and its split-half reliability was 0.60.Criterion-related validity studies showed that the scores of the 18 items were positive correlated with SDS and SAS(r SDS =0.50,r SAS =0.54,P＜0.01).This scale also had good structure validity.3.The ROC curve concluded that the area under curve was 0.83,the sensitivity was 68.40％ and the specificity was 79.20％.Positive and negative predictive values were 21.22％ and 96.83％ respectively.Conclusion The reliability and validity of the warning scale entirely accorded with psychometric demands.It also has good specificity and negative predictive value,so it is suitable for clinical promotion.

Objective To discuss fluvastatin intervention on ventricular remodeling and plasma brain natri-uretic peptide( BNP) levels in dilated cardiomyopathy( DCM) .Methods 64 cases of DCM patients were selected and randomly divided into the intervention group and control group,each group in 32 cases.Both groups were treated with conventional drug therapy, including angiotensin-converting enzyme inhibitors,β-blockers, diuretics, etc.In conven-tional drug treatment intervention group based on the use of fluvastatin 40mg/d.Intervention in both groups before and 6 months after the intervention,plasma BNP levels were examined and ventricular remodeling indicators,analyzed and compared using Pearson Univariate correlation of each index.Results The total efficiency of the intervention group was higher than that of the control group(87.51%vs 65.63%,χ2 =4.730,P<0.05);6 months after the interven-tion groups,plasma BNP levels were significantly decreased left ventricular ejection fraction(LVEF),left ventricular end systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD) and relative wall thickness(RWT) were significantly improvements.BNP levels and LVEF and RWT was negatively correlated( r=-0.45,-0.39,all P<0.05);Positively correlated with LVESD and LVEDD showed(r=0.35,0.44,all P<0.05),the difference was statistically significant.Conclusion Fluvastatin intervention can significantly reduce plasma BNP levels in DCM and improve ventricular remodeling.

Objective To assess the outcomes of modified spiral ileal orthotopic neobladder.Methods From January 1998 to January 2008, 32 patients (all male) underwent radical cystectomy and spiral ileal orthotopic substitution for muscle invasive bladder cancer. A segment of 40 to 45 cm ileal loop was isolated, detubularized, and reconfigured in spiral shape to form a pouch. Bilateral ureters were reimplanted by inserting the 1 cm distal segment into the pouch to form a Split-Cuff nipple.The bottom of the pouch was opened and anastomosed with the urethra (4 stitches). Results There were no perioperative deaths. The mean operative time was 281.2±48.7 min. Blood loss was 545.4±181.9 ml. Twenty cases required a blood transfusion, the mean volume of intraoprative blood transfusion was 430.8±235.9 ml. The average hospital stays were 26.8±9. 7 days. Rate of daytime continence was 93. 7% (30/32) while nighttime continence was 81.3% (26/32). Urodynamic studies were carried out in 23 cases 6 months after surgery. Neobladder capacity at first desire to urinate was 315.0± 33.4 ml(270-420 ml). The maximum neobladder capacity was 490. 3±39.7 ml(350-600 ml).The maximum flow rate (Qmax) was 16.5 ± 5.9 ml/s. Full resting pressure was 22. 5 ± 11.8 cm H2O. Peak voiding pressure was 78.3 ± 14.7 cm H2O. After mean 58. 4 months' follow up (range 22 to 132), 4 cases died of metastasis of bladder cancer. Conclusion Modified spiral ileal orthotopic neobladder is a reasonable option for treating invasive bladder cancer.

Objective To investigate the clinical characteristics and prognosis of patients with systemic lupus erythematosus (SLE) complicated with acute pancreatitis (AP) .Methods From January 1999 to December 2013 ,the clinical data of 16 patients with SLE complicated with AP among the total 2 526 cases of SLE was collected .A retrospective analysis was performed and the clinical data of patients was classified and documented ,which included general information ,past history ,clinical symptoms , laboratory findings ,imaging findings ,treatment and outcome .The rank sum test was performed for analysis of non‐normal distributed measurement data ,and the Fisher′s exact test was used for count data analysis .Results The incidence of SLE complicated with AP was 0 .63% (16/2 526) .Among them ,ten patients were mild acute pancreatitis (MAP) and six patients were severe acute pancreatitis (SAP) .All patients were treated with fasting ,gastrointestinal decompression ,nutritional support ,anti‐acid ,anti‐inflammatory ,glucocorticoid and somatostatin and so on . Six patients were cured , seven patients improved and three patients died (two SLE complicated with SAP ,one SLE complicated with MAP) . Compared with the SLE patients complicated with SAP ,the SLE patients complicated with MAP were more easily to have lupus nephritis(6/6 versus 5/10 ,Fisher′s exact test) ,hematological system injuries (6/6 versus 5/10 ,Fisher′s exact test) ,liver injuries (5/6 versus 0/10 ,Fisher′s exact test) ,more organs involved (mean 7 versus 3 ,Z= -3 .225) and higher SLE disease active indexes (DAI) score (mean 13 .5 versus 6 .5 ,Z= -2 .876);the differences were statistically significant (all P<0 .05) .Compared with the cured and improved SLE patients complicated with AP ,lupus encephalopathy (2/3 versus 1/13 ,Fisher′s exact test) ,more organs involved (mean 7 versus 5 ,Z= -2 .276) and higher SLE DAI score (mean 21 versus 12 ,Z= -2 .195) was more common in dead SLE patients complicated with AP;the differences were statistically significant (all P< 0 .05) .Conclusions SLE patients complicated with SAP are more easily to get lupus nephritis ,hematological system injuries ,liver injuries ,activity of SLE and multiple‐organ systems involved . The prognosis of SLE patients complicated with AP was poor in those with activity of SLE ,multiple‐organ involved and lupus encephalopathy .
