[Objective] To summarize image manifestations in intestinal tuberculosis (ITB) examined by multi-slice computed tomography enteroclysis (MSCT) and evaluate the diagnostic value of MSCTE in ITB,[Methods] The imaging findings were retrospectively analyzed in 15 cases of ITB that were confirmed by endoscopy or postoperative pathologic examination,including the location,number,shape,edge,surrounding tissue alterations of ITB and other associated changes in the peritoneum,mesentery and solid abdominal organs,and compared with endoscopy and pathology.[Results] In 15 patients,ileocecum was involved in 13 cases (87%),4 cases (27%) showed multi-segmental symmetric intestinal mural thickening,9 patients (60%) showed solid masses,1 case (7%) showed multi-segmental symmetric intestinal mural thickening and solid masses,1 case (7%) showed homogenous enhanced masses and perforation,12 cases (86%) showed enlarged lymph nodes (LNs) with rim enhancement,and 2 cases (13%) showed the comb sign of enhanced mesenteric vessels.Based on enhancement pattern of MSCTE,ITB was divided into three types:homogenous enhancement type (n=5);target sign type (n=2);caseous necrosis type (n=2).[Conclusion] The imaging features of ITB are diverse.MSCTE can clearly display the shape of intestinal mucosa,the alterations of intestinal wall and the relationship between lesion and adjacent tissues,which provides valuable information for the clinic diagnosis of ITB.

Objective: To study the expression and localization of apoptosis-related protein TFAR19 in TF-1 cells undergoing apoptosis. Methods: Using monoclonal antibody against TFAR19, the expression level and cell localization of TFAR19 were examined by fluorescence microscope, confocal laser scan microscope(CLSM) and flow cytometry. Simultaneously, we also analyzed the relationship of TFAR19 protein with phosphatidylserine (PS) externalization and cell nuclear DNA fragmentation. Results: The level of TFAR19 proteins expressed in TF-1 cells treated with GM-CSF withdrawal was significantly increased compared with normal TF-1 cells, then translocated rapidly from cytoplasm to the nucleus of cells. Appearance of TFAR19 in the nucleus of apoptotic cells preceded the detection of PS externalization and DNA fragmentation. Conclusion: Nuclear translocation of TFAR19 protein is one of the earliest events of cell apoptotic process. These data provided a new clue to further approach to the biological function of TFAR19 and study of cell apoptosis.

ObjectiveTo investigate the impact of antimicrobial resistance on clinical outcomes and medical care costs among patients with imipenem-resistant Acinetobacter baumannii (IRAB) nosocomial infection.MethodsA retrospective matched case-control study was performed to compare the differences of clinical outcomes and medical care costs between patients with IRAB infection and patients with imipenem-susceptive Acinetobacter baumannii (ISAB) infection in a tertiary care university teaching hospital in China from January 2007 to June 2009.Cases were matched to controls with ratio of 1:1 on the basis of age,sex,severity of underlying diseases,source of infection,duration of hospitalization period and length of hospital stay before onset of infection.The measurement data between groups were compared by t test and rank test.The numeration data between groups were compared by x2 test. Multiple analysis was performed by Logistic regression.ResultsThe total mortality rate of IRAB infection patients was significantly higher than that of ISAB infection patients (39.1% vs 20.3 % ; x2 =11.728,P<0.01).Among 138 pairs of patients in IRAB group and ISAB group,there were 72 matched case-control pairs survived,which were significantly different in length of total hospital stay (28.5 days vs 23.0 days; x2 =2.886,P<0.01) and intensive care unit (ICU) stay (14.5 days vs 0 day; x2 =4.844,P<0.01).For all the 138 case-control pairs,everyday total hospitalization cost and everyday antibiotic therapy cost in IRAB cases were both higher than ISAB controls (RMB 3652 yuan vs RMB 2092 yuan; Z=3.792,P<0.01 and RMB 555 yuan vs RMB 338 yuan; Z=4.209,P<0.01).ConclusionIRAB infection can increase the mortality rate,lengthen hospital stay and elevate the medical costs notably.

Objective To study the tactics, methods and relevant factors of interventional treatment for hemorrhage following biliary and pancreatic surgery.Methods Fourteen patients with hemorrhage following biliary and pancreatic surgery were treated by embolization using gelfoam pledgets, PVA granules, metal coils or otherwise by local infusion of vasopressin. Results There were 16 foci in 14 patients with 16 times of interventional treatment, including 3 times using metal coils, 6 times of PVA, 2 gelfoam pledgets, 1 with PVA plus gelfoam pledgets, and 4 of vasopressin. There was 1/16 time failure of using vasopressin due to anastomotic rupture. The successful rate reached 93.8%. Conclusions Interventional treatment is a safe and effective method for hemorrhage following biliary and pancreatic surgery. The key of success is the right selection of embolization or vasopressin infusion for target artery.

The aim of this study was to identify antigens for a vaccine or drug target to control rabbit coccidiosis. A combination of 2-dimensional electrophoresis, immunoblotting, and mass spectrometric analysis were used to identify novel antigens from the sporozoites of Eimeria stiedae. Protein spots were recognized by the sera of New Zealand rabbits infected artificially with E. stiedae. The proteins were characterized by matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF/TOF-MS) analysis in combination with bioinformatics. Approximately 868 protein spots were detected by silver-staining, and a total of 41 immunoreactive protein spots were recognized by anti-E. stiedae sera. Finally, 23 protein spots were successfully identified. The proteins such as heat shock protein 70 and aspartyl protease may have potential as immunodiagnostic or vaccine antigens. The immunoreactive proteins were found to possess a wide range of biological functions. This study is the first to report the proteins recognized by sera of infected rabbits with E. stiedae, which might be helpful in identifying potential targets for vaccine development to control rabbit coccidiosis.

Ovarian Leydig cell tumor(LCT), also known as ovarian testicular stromal cell tumor, is a rare sex cord stromal tumor, accounting for about 0.1% of all ovarian tumors. LCT is often accompanied by clinical manifestations of elevated androgen, and the imaging manifestations sometimes lack specificity. The diagnosis requires histopathological examination. Surgery is the primary treatment method, and postoperative prognosis is generally favorable. This paper retrospectively analyzes the diagnosis and treatment of a patient with LCT in our hospital combining relevant literature, explore the clinical characteristics, diagnosis, and treatment progress of LCT, aiming to improve disease management.

Objective:
To detect the effect and regulatory mechanism of human ether à go-go related gene 1 (Herg 1) knockdown on the proliferation and invasion of osteosarcoma (OS).
Methods:
We constructed a recombinant adenovirus vector (Ad5-Herg1-shRNA) expressing short hair RNA (shRNA) against Herg1 and tested the knockdown efficiency. Then, the effects of Herg 1 knockdown on the proliferation, growth and invasion of osteosarcoma were measured by using cell counting kit-8 (CCK-8), wound healing assay, Transwell assay and xenograft model of nude mice, respectively. Tandem affinity purification, mass spectrometry and dual luciferase reporter assay were used to find out the molecules interacted with Herg1. Western blot was used to detect the expressions of large tumor suppressor gene (LATS1), p-LATS1, Yes-associated protein (YAP) and p-YAP in cells after infection of Ad5-Herg1-shRNA.
Results:
Compared to Ad5-control-shRNA, Ad5-Herg1-shRNA dramatically inhibited the expression of Herg1 in OS cells. The result of CCK8 array demonstrated that 143B cell vitalities of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (65.47±3.90)% and (79.90±1.52)%, significantly lower than (100.00±6.14)% of Ad5-control-shRNA group. Meanwhile, U2OS cell vitality of Ad5-Herg1-shRNA1 and Ad5-Herg1-shRNA2 group were (69.69±1.36)% and (76.72±2.75)%, significantly lower than (100.00±3.01)% of Ad5-control-shRNA group (all
