Objective To observe the effect of laparoscopy combined with choledochoscopy in treatment of cholelithiasis clinical effect .Methods 80 cases diagnosed as cholelithiasis cases were divided into control group and observation group with 40 cases in each group .The control group used the traditional laparotomy incision gallbladder stone ;observation group were treated by laparos-copy combined with choledochoscopy .Results In the observation group ,the operation and the hospital stay were significantly shor-ter than the control group ,operation curative effect was obviously superior to the control group ,the incidence of postoperative com-plications was significantly lower than the control group .Conclusion The use of laparoscopy combined with choledochoscopy tech-nology in treatment of gallstones have good clinical effect .

The effects of external factors, internal factors and behavior outcomes on reading behaviors of university undergraduates in China and the role of library in their reading were analyzed with the associated problems pointed out and suggestions proposed for their solution.

Objective To test the reliability and validity of the home care demand forecasting scale for fracture patients when they were before discharge. Methods This study was descriptive study. Convenience sampling was used and 412 patients with fracture from 5 comprehensive hospitals in Yanbian Korean Autonomous Prefecture were selected. Finally, the number of valid questionnaires is 398 which were used for testing. Results Five factors and 32 items were eventually determined. The split-half reliability coefficient was 0.910, and split-half coefficient in each dimension was over 0.75; the content validity showed scale level content validity index(S-CVI) was 0.948, and the index in each item′s item level content validity index (I-CVI) was between 0.76 to 1.00. The result of factor analysis included 5 factors and the cumulative contribution of variance was 59.181%. The result of construct validity χ2/df=1.554, root mean square error approximation (RMSEA)=0.037, goodness-of-fit index (GFI)=0.920. The total of scale′s Cronbach coefficient was 0.948, Each dimension′s Cronbach coefficient was between 0.797-0.875. Conclusions The home care demand forecasting scale was proved to be reliable and valid. It can be used to assess the home-care needs of fracture patients before they were discharge.

After the functions and requirements of medical information officers and the distribution of enterprises were described, the problems in domestic education of medical informatics ( such as insufficient class hours for medical course and unclear orientation of subjects) were analyzed according to the status quo in training of medical informatics students, and some suggestions were put forward for the orientation of medical informatics education in China.

Purpose:To study the relationship between expression of TGF-?_(1) and invasion and metastasis of bladder cancer.Methods:ELISA was used to examine TGF-?_(1) in serum of patients with bladder cancer.Results:Compared to the control group,TGF-?_(1) level in patients serum was higher(P

Objective To investigate the surgical correction of alar deformity and repairing function of unilateral cleft lip in infant. Methods Millards procedure was used to incise skin, muscle and mucosa, correct the nasal deformity through lip. At the normal side, ophthalmic scissors was applied to incise lips muscle and skin, and reach the deep level of the base of nasal pillor, cut the abnormal attachment between the orbicular muscle of mouth and anterior nasal spina, and sharp dissect cartilage and skin in nasal wing through deep level of nasal pillor. At the cleft side, the abnormal muscle branch was cut that attached at the down side of the base of nose and pyriform aperture, the tissue between nasal base and lip, maxilla relaxed, and the cartilage and skin in the nasal wing at the same side dissected. The deform cartilage was repairied as the same of normal side. After the rehabilitation of cartilage of nasal wing, the soft tissue at deep level was moved to normal location, but the deep level structure of nasal wing cartilage, nasal septum cartilage and nasal bone did not dissected. After the dissection of orbicular muscle of mouth, the muscle in nose and lip must be relaxed in illous side. The orbicular muscle of mouth was sewed under the condition of tensionless. The repairing of orbicular muscle of mouth will improve the balance of muscular strength around the nose. Thus, the deviation of nasal pillor was corrected and the base of nose repaired. Results Eighty cases of infant with unilateral cleft lip at the age of 3 months ～12 months, in which 11 cases were Ⅰ?,16 Ⅱ, and 3 Ⅲ?. Eighty cases were low grade alar deformity, and 13 middle grade deformity. After operation, 52 cases were better, 17 cases were good, and 11 cases were worse. The postoperational result was good. Conclusion While performing the cleft lip operation or Millard operation, the authors can correct the nasal deformity through lip. So, it is recommended that cleft lip and the alar deformity can be repaired at the same time.

Objective To observe the expression of OBR and NPY in mouse hypothalamus.Methods In mouse hypothalamus,the location and coexpression of OBR and NPY were observed with immunohistochemistry and double immunohistochemistry.Results OBR positive cells distributed as clump in hypothalamus ME,ARC and VMN,having obscure boundary.OBR positive cells were also present in choroid plexus,brain ependymal layer cell and vascular endothelial cells.In hypothalamus ARC,NPY positive neurons were present with bright red color in cell plasma.The NPY positive neurons were found as round or ellipse,having many neurites.NPY positive fibers were present in ME.In double immunohistochemistry result,the coexpression of OBR and NPY showed black color,because that OBR positive cells showed brown purple or dark purple granula near the NPY positive neurons.Conclusion OBR distributed in ME,ARC,VMN of mouse hypothalamus,choroid plexus,brain ependymal layer cells and vascular endothelial cells.Meanwhile NPY also distributed in ME,ARC,cerebral cortex and hippocampus and so on.Moreover the coexpression of OBR and NPY was present in mouse hypothalamus ARC.

Red fluorescent proteins (RFPs) produced from a number of Anthozoa species have been subjected to a series of in vitro molecular evolution, resulting in various emission spectra ranging from 570 nm to 655 nm and thus providing powerful tools for cellular imaging or even body imaging. This article briefly reviewed the optical properties, structures and mutagenesis of RFPs and their applications.
