OBJECTIVETo investigate diagnostic efficacy of transvaginal three-dimensional hysterosalpingo-contrast sonography (3D-HyCoSy) in assessing tubal patency with chromolaporoscopy.

METHODSA total of 157 infertile women underwent 3D-HyCoSy to evaluate tubal patency. Among these patients, 39 patients were also examined by chromolaporoscopy. The concordance of the two clinical assessment methods was analyzed by the Kappa coefficient test.

RESULTSAmong the 306 oviducts examined by 3D-HyCoSy, 99 (32.4%) were patent, 126 (41.2%) partially obstructed, and 81 (26.5%) completely obstructed. Diagnostic results with 3D-HyCoSy were not statistically different from those obtained in the 39 women (78 oviducts) who also underwent chromolaporoscopy, and the two methods showed a high concordance (k=0.747, P=0.000). The 3D-HyCoSy procedure had a sensitivity of 84.8% (28/33), a specificity of 96.2% (25/26), and positive and negative predictive values of 93.3% (28/30) and 86.2% (25/29) respectively.

CONCLUSIONTransvaginal 3D-HyCoSy can accurately reveal the spatial path and morphology of the oviduct and is a safe and effective method to evaluate tubal patency.

Objective To discuss the common causes for postoperative complications after treatment of spinal fractures and their preventive measures.Methods To analyze the 32 failed eases who received internal fixation for their thoracolumbar fractures between July 1998 and April 2005 in our department.Their preoperative and postoperative results of X-ray,CT and MIR examinations were reviewed to find out the causes for failure.Three of them were treated through anterior approach and 29 through posterior approach.Eighteen screws broke in eight eases, the rods got loosened in eight cases and broken in four cases,15 pedicte screws were mis-located in eight cases and the implants got loosened in three cases.Results Thirty patients had to get a reoperation.Two were cured through non-surgical treatment.The causes for failure were found to be as follows:1,incorrect operation approach;2,in- stability of the front-middle colunm;3,unskillful operation;4,ignorance or the lesion to the adjacent vertebral discs; 5,flaws in pedicle screw design.Conclusion To prevent postoperative complications after internal fixation for spinal fractures,surgeons should strictly stick to the indications before operation,choose a proper approach and method for internal fixation,try to stabilize the front-middle column by the first intention,and have a good command of anatomy and operation skills.

Objective Respiratory syncytial virus (RSV) is the most common cause of lower respiratory infection in infants.It is very important to quantitative assay of RSV titer in the study on RSV pathogenesis,candidate vaccine and antiviral treatment.Therefore,we develop Real-time Quantitative PCR (Q-PCR) assay and enzyme immunospots (EIS) for titrating RSV and compare them with traditional 50% tissue culture infectious doses (TCID_(50)).Methods Q-PCR,based upon the RSV-L genes,and EIS were utilized to titrate samples from RSV culture supernatants and RSV infected mouse lungs.Then,the results were compared with TCID_(50).Results For the samples from RSV culture supernatants,the ratio of Q-PCR and EIS (plaque forming unit,pfu) was 10:1 and the ratio of EIS and TCID_(50) was 10:1 when TCID_(50) was converted as pfu.For the samples from RSV infected mouse lungs,the ratio of Q-PCR and EIS was 1000:1 and the ratio of EIS and TCID_(50) was 5:1.Conclusion We have successfully established Q-PCR and EIS to titrate RSV and compared them with TCID_(50).We concluded EIS is a cost-effective method to titrate RSV.

Proteomics, which has been widely used in life science, is an emerging discipline following genomics. It can help to explore the pathogenic mechanism and early onset marker of Bacillus anthracis, playing an important part in the prevention, diagnosis and treatment of B.anthracis. In this paper,the application of proteomics in the research of B.anthracis is reviewed.

Mouthpart developmental histology of Whitmania pigra at different month of age were studied by paraffin section, HE staining combined alcian blue and periodic acid schifts reaction procedure (AB-PAS). The following results was obtained: Change ranges: oral width 0.6 mm (1-3 month), 1.2 mm (34 month); oral diameter 0.3 mm (1-3 month); 1.2 mm (34 month), the oral size reached maximum during 4-6 months and unchanged thereafter. Oral lip had a thin protective film located in the front of the mouthpart. The W. pigra possessed three jaws in oral cavity, the big one was in dorsum, the other two separated on both side of abdomen respectively. Jaws and muscular pharynx were interrelated closely. The jaws were composed by cuticle, epithelial layer, muscularis and jaw cavity from outside to inside. In the front of jaws had mastoid abdomen with function of secreting acidophilic granule from 2 month age. Oral cavity was composed by mucosa, submucosa and muscularis inside and outside. Oral cavity was rich of peristomial nerves. And pharynx was composed of mucosa, muscularis, adventitia from inside to outside. The folds height and width become heighten and thicken. Mucosa epithelium from complex flat epithelium changed into columnar epithelium, muscularis gradually developed into thickened along with growing. Muscular thickness reached maximum at 4 months. Mucous cells of W. pigra were classified into I-IV types based on different staining and two mainly morphological shapes (Tubular, Pear-shaped). Jaws, oral cavity, pharynx by AB-PAS staining showed little changes at different month of age. Mucous cells were few at 1 month age, and type II cells were increased rapidly in 2-3 month age in oral lip. Oral cavity contains more mucous gland cells type I. Under the muscularis there were connective tissues which distributed a few of mucous cells type II.

Objective:To detect the expression of Shank1 protein in renal cell carcinoma (RCC), to investigate its difference between the tumor and carcinoma adjacent tissue, and to analyze its correlation with RCC clinicopathological characteristics and prognosis. Methods:The renal carcinoma and carcinoma adjacent tissues of 120 patients were selected from Cangzhou Central Hospital and Ji'nan Central Hospital from May 2008 to December 2014. The expression level of Shank1 was determined by immunohistochemistry and Western blot. Statistical analysis was performed to determine the relationship between the expression of Shank1 and the clinicopathological features of RCC patients. Results:Results of immunohistochemistry showed that the expression level of Shank1 in renal cancer tissue was significantly higher than that in carcinoma adjacent tissue, and the difference was statistically significant (P<0.05). Western blot results showed that the expression level of Shank1 protein in renal cancer tissue was also significantly higher than in carcinoma adjacent tissue. Correlation analysis found that the high expression level of Shank1 in renal cancer tissue was not significantly related to gender, age, tumor size, and TNM stage, but was significantly associated with the histological differentiation of RCC (P<0.05). Conclusion:Shank1 is abnormal y expressed in RCC renal cancer tissues and is correlated with the histological differentiation of RCC.
