Objective To investigate operative methods and indications for the surgical repair of hypospadias. Methods Clinical data of 91 cases of hypospadias repaired in this hospital between 1997 and 2003 were retrospectively analyzed. Results Postoperative urethral fistula took place in 15 cases, with an overall incidence of 16 5% (15/91), including 6 cases treated by Duckett procedure, 4 cases treated by Duckett combined with Duplay procedure, 1 case treated by Mathieu procedure, 2 cases treated by scrotal island flap procedure (Onlay procedure), 1 case treated by Denis-Browne procedure, and 1 case treated by Snod-grass procedure. Conclusions For patients with hypospadias associated with serious chordee, because the urethral plate can not be preserved, adaptable methods should include scrotal island flap procedure, Duckett procedure, or Duckett procedure combined with Duplay procedure. Urethral plate conserving operations are suitable for hypospadias without chordee or with mild chordee, involving the Mathieu procedure, Onlay procedure, Snod-grass procedure and Denis-Browne procedure.

BACKGROUND: The expression of Fas antigen and P53 protein in colorectal cancer could reflect the biological character and the prognosis of the tumor.OBJECTIVE: To investigate the relationship between the expression of Fas antigen and P53 protein in coloreetal cancer and the tumor-related biological characters.DESIGN: A controlled experiment by introducing pathological specimens as subjects.SETTING: The study was conducted in the Department of Pathology of Xijing Hospital Affiliated with the Fourth Military Medical University of Chinese PLA.PARTICIPANT S: Totally 32 pathological specimens of colorectal cancer were randomly selected from the Department of Surgery of Xijing Hospital between January 1995 and October 1998. Sixteen normal large intestine tissues were selected form the cadaver of pathology department.METHODS: The expression of Fas antigen and P53 protein in 32 colorectal cancer tissue and 16 normal intestine tissue were tested and compared with immunohistochemical method.MAIN OUTCOME MEASURES: Fas antigen and P53 protein expression in coloreetal cancer and normal intestine, and the clinical indicators of patients with colorectal cancer.RESULTS: The expression of Fas antigen was positive in normal large intestine tissue while the expression of P53 protein was negative. The positive rate of Fas antigen expression in colorectal cancer was 41% (13/32), while the positive rate of P53 expression in colorectal caner was 53% (17/32). Fas antigen significantly decreased in colorectal cancer tissues. The expression of Fas antigen was correlated with the histological type of colorectal cancer and its liver metastasis( P ＜ 0.05) . And the expression of P53 protein was correlated with the liver metastasis of colorectal cancer( P ＜ 0. 05).CONCLUSION: The expression of Fas antigen significantly decreases in colorectal cancer. The higher the malignance is, the more significant less the expression is. Fas antigen does not express in liver metastasis patients. P53protein had positive expression in colorectal cancer tissues, especially in patients with liver metastasis. The reduction and deletion of Fas antigen expression and the excessive expression of P53 protein indicate poor prognosis.

Objective To investigate haemodynamic change during hemodialysis and analyze effects of cardiac index (CI) on hemodynamic parameters and associated influencing factors in maintenance hemodialysis (MHD) patients.Methods Seventy-five patients bearing an arteriovenous fistula (AVF) entered the study.Cardiac output (CO),cardiac index (CI),central blood volume (CBV) and peripheral vascular resistance (PR) were determined by ultrasound dilution technique at the end of 1 hour,2 hours and 3 hours of dialysis.AVF blood flow (Qa) was also measured with the same device before haemodynamic parameters investigation.Results Mean age of patients was (55.84 ±12.39) years old (range 21-81 years) and 43 patients (57.3％) were female.Systolic arterial pressure,SV,CO,CI and CBV were significantly declined and no significant change for diastolic arterial pressure and heart rates at the end of 2 hour and 3 hour hemodialysis,whereas PR was increased gradually during hemodialysis.Patients were divided into there groups with CI less than 2.5 L·min 1·(m2)-1,2.5-4.2 L·min-1·(m2)-1 and more than 4.2 L·min-1 ·(m2)-1 at the end of 1 hour dialysis.Statistically significant decreasing SV,CO and increasing PR were detected in patients with CI＜2.5 L·min-1· (m2)-1 and 2.5-4.2 L· min-1· (m2)-1,compared with CI＞4.2 L·min-1· (m2)-1 group (P＜0.01).The hemodynamic change was the most obvious in the group of CI less than 2.5 L· min-1· (m2) 1,and no significant changes happened in CI＞4.2 L·min-1 ·(m2)-1 group.Some factors were found to be associated to CI values.Qa and systolic arterial pressure had positive relationship with CI,while age and diabetes had negative relationship with CI.Conclusions Systolic arterial pressure,CO,CI and CBV decrease and PR increases during hemodialysis.Obvious change occurs when CI is less than 2.5 L·min-1· (m2)-1.CI is associated with Qa,systolic arterial pressure,age and diabetes.

Objective To explore whether miR-451 suppresses cell migration and invasion by targeting macrophage migration inhibitory factors (MIF),thus to reveal molecular mechanism that miR-451 functions as a tumor suppressor in gastric cancer.Methods A quantitative real-time polymerase chain reaction (qRT-PCR) was carried out to detect the expression of miR-451 in gastric cancer and normal stomach mucosa.Western blotting was performed to detect the expressions of MIF protein regulated by miR-451 in MGC 803 cells.The migration and invasion abilities of MGC-803 cell were evaluated with wound-healing and transwell invasion assays.Results miR-451 was down-regulated in gastric cancer tissues.The expressions of miR-451 were negatively correlated with the clinical stage and lymph node metastasis in gastric cancer patients.Western blot showed that a notable reduction of the protein level of MIF by restoring miR-451 in MGC-803 cells.Overexpression of miR-451 inhibited the migration and invasion of MGC-803 cells.Conclusions miR-451 suppresses cell migration and invasion by targeting MIF in gastric cancer.

Background:The incidence of ischemic colitis(IC)is increasing in recent years with the aging of population,and the rate of delayed diagnosis or misdiagnosis is high because of the lacking of specific clinical characteristics. Aims:To study the clinical characteristics of IC so as to improve its early diagnosis and treatment. Methods:The clinical and endoscopic characteristics of 75 IC patients from Jan. 2009 to Dec. 2014 at Urumqi General Hospital were retrospectively analyzed. Results:IC usually occurred in elderly patients with age ≥60 years,females were more common. Most patients had underlying diseases,including hypertension,coronary heart disease,diabetes,hyperlipidemia and arrhythmia,etc. Colonoscopy and medications could also induce IC. The main clinical presentations were abdominal pain,hematochezia and diarrhea. The lesions were mostly located in left colon and of the transient type. Conclusions:IC should be suspected when elderly patients with underlying diseases,complaining abdominal pain,hematochezia and diarrhea,colonoscopy and pathologic study should be undertaken as early as possible. Prognosis is good when treated timely.
