Objective To explore the diagnostic value of endoscopic retrograde cholangio-pancreatiography (ERCP),ultrasonography (US) and CT scanning on cholagio-pancreatic diseases caused by clonorchis sinensis infection.Methods The results of US,CF and ERCP examination in 65 cases of obstructive jaundice caused by clonorchiasis and confirmed by presence of imagoes or eggs in feces or bile juice were analyzed and compared retrospectively.Results US examination was the simplest and most convenient which was characterized by diffuse even dilatation,thickening of walls,strengthened echo with the shape of“equal sign”intrahepatic bile ducts.The characteristic findings of CT included saccular dilatation of bile ducts of the periphery of the liver,thickening of the walls of bile ducts.Under duodenoscopy,32.3% (21/65) of cases presented as abnormal papilla such as small opening,mucosa outward turned,trapping or stiffness.Alterations in ERCP were characterized by shm or oval filling defect,diffuse saccular dilatation of terminal intrahepatic bile ducts.The most common complications included cholangiolithiasis (40%,26/65),carcinoma of bile duct on papilla (9.8%,6/65),and pancreatitis (1.5%,1/ 65).Conclusions Three methods were all useful for diagnosis of cholangio-pancreatic diseases caused by clonorchis sinensis infection,which were identically characterized by diffuse saccular dilatation of terminal intrahepatic bile ducts.The gold standard of diagnosis was the presence of imagoes or eggs in bile juice aspirated by the route of ERCP.Endoscopic sphincterectomy with postoperative vermifugal was the first choice of the treatment.

OBJECTIVETo investigate the clinical application of pedicled superficial circumflex iliac artery (SCIA) flaps in Burns and Plastic Surgery.

METHODS19 cases with skin and soft tissue defects were repaired with the Superficial circumflex iliac artery flaps. The defects located in the hand and forearm, the lower abdomen and perineal area, the radicle area of thigh, etc. Before the SCIA flaps were transfered to the recipient areas, 15 cases with different kinds of wounds were debrided thoroughly, 3 cases with scar were removed directly. The size of the flaps ranged from 3.0 cm x 4.5 cm to 26.0 cm x 22.0 cm, and the pedical was 5 cm to 7 cm in length.

RESULTSThe flaps in the 18 cases survived completely. Skin necrosis in the distal end of the flap appeared in 1 case, and the wound healed after the second repair. The follow-up period rang from 3 to 18 months. The apperance and function of the hand or foot was satisfactory.

CONCLUSIONSBecause the pedicled SCIA flaps can be obtain conveniently and contain sufficient blood-supply, so the flap is easy to survive and the flap can be designed in a large size. We believe it is an ideal method to use this flap to repair skin and soft tissue defects located in hands, forearms, the lower abdomen and perineal areas, the radicle area of thigh and so on.

Spinal biomechanics, especially the range of spine motion,has close connection with spinal surgery. The change of the range of motion (ROM) is an important indicator of diseases and injuries of spine, and the essential evaluating standards of effect of surgeries and therapies to spine. The analysis of ROM can be dated to the time of the invention of X-ray and even that before it. With the development of science and technology as well as the optimization of various types of calculation methods, diverse measuring methods have emerged, from imaging methods to non-imaging methods, from two-dimensional to three-dimensional, from measuring directly on the X-ray films to calculating automatically by computer. Analysis of ROM has made great progress, but there are some older methods cannot meet the needs of the times and disappear, some classical methods such as X-ray still have vitality. Combining different methods, three dimensions and more vivo spine research are the trend of analysis of ROM. And more and more researchers began to focus on vivo spine research. In this paper, the advantages and disadvantages of the methods utilized recently are presented through viewing recent literatures, providing reference and help for the movement analysis of spine.

By analyzing the epidemiological and clinical features of adenovirus in children with acute respiratory tract infection (ARTI), we provide a theoretical basis for early clinical diagnosis and treatment. Nasopharyngeal secretions were collected from 3480 children with ARTI, who were hospitalized at the No. 2 Hospital of Changzhou from January 2011 to December 2012. Adenovirus were detected using direct immunofluorescence assays. A total of 80 samples were positive for adenovirus (2.30%). The rate of adenovirus infection during 2011 was significantly higher than that in 2012, and the infection rate was higher in summer and autumn than in winter and spring. The infection rate was 1.14% among children aged < 1-year-old and the rates were higher among children in other age ranges. Adenovirus was found to be an important ARTI pathogen in children in Changzhou, mainly affecting children older than 1 year. ADV infections have various clinical presentations, but affected children tend to be severely ill with poor outcomes.

Objective To establish a novel TRFIA for the measurement of heparanase (HPA) in serum samples,and investigate its clinical application.Methods The micro-pore plate wells were first coated with partially recombinant murine anti-human HPA monoclonal antibody.Biotin-labeled recombinant HPA protein was then used to compete with HPA in serum samples,and the prepared europium (III)-labeled streptavidin (Eu3+-SA) was used as signal readout for establishing the BSA-TRFIA assay.Using this assay,the serum HPA levels in healthy subjects (n=32) and tumor patients (n=54) were measured.The results of BSA-TRFIA were compared with those of ELISA.Two-sample t test (or t' test),and linear correlation analysis were used to analyze the data.Results The sensitivity of BSA-TRFIA for measuring HPA was 0.33 ug/L.The CV values for intra-batch and inter-batch were 5.29% and 7.54%,respectively.The average recovery rate was 105.5%.The standard curve range was 0-1 000 ug/L.The serum HPA level measured by the BSA-TRFIA method in healthy subjects was (2.03_+ 1.47) Iug/L.In tumor patients,the HPA level was significantly higher:(22.13_+7.38) ug/L (t'=19.388,P

Multiple myeloma (MM) is a plasma cell malignancy characterized by the high capacity to induce bone destruction. Osteolytic bone lesions in MM patients mainly result from an increased bone resorption related to the stimulation of osteoclast recruitment and activity. SDF-1a would represent a potential role and may provide a suitable therapeutic target for MM-mediated osteolysis. In this article the structure of SDF-1/CXCR4, the expression of SDF-1/CXCR4 in bone microenvironment of MM patients and its effect on osteoclasts, relation of SDF-1/CXCR expression with osteolytic bone lesions and prognosis of MM, SDF-1/CXCR4 as potential target for treatment of myeloma-osteopathia were reviewed.
