The sphincter of Oddi is a valve that controls the biliopancreatic duct and plays an irreplaceable role in maintaining normal physiological functions of the biliopancreatic duct.However,sphincteroplasty and sphincterotomy may cause varying degrees of damage to the function of the sphincter of Oddi,which may further result in postoperative reflux of duodenal fluids and bacterial contamination in bile and increase the risks of recurrent common bile duct stones,reflux cholangitis,and even cholangiocarcinoma.Therefore,clinical physicians should protect the structure and function of the sphincter of Oddi.Based on our experience,under the premise that the extrahepatic bile duct can be preserved,patients with iatrogenic injury of the sphincter of Oddi can be treated with transduodenal sphincteroplasty to restore the structural integrity of the sphincter of Oddi and reduce biliopancreatic duct complications secondary to loss of function.

Optimization of surgical treatment of biliary dilatation (BD) depends on reasonable clinical classification and standardized classification-based treatment strategy.Due to increasing limits and defects of classic Todani classification,a new classification named Dong-classification has been proposed,which was based on a large series analysis from a single referral center.Some important parameters including anatomical location and range of BD,pathogenic factors,and different surgical managements were main considerations in the new classification.After practical application and evaluation,Dong-classification has been improved step by step.It is believed that Dong-classification may contribute to improving surgical treatment decision and selecting reasonable operative plan.

Objective To investigate the expressions of COX-2 and p53 in human colorectal carcinoma and their correlations with clinicopathological features of colorectal carcinoma. Methods The expressions of COX-2 and p53 were determined by immunohistochemical staining in 72 surgical specimens of colorectal carcinoma and 21 normal mucosal tissues. Results The positive rates of COX-2 and p53 in colorectal carcinoma were 70.8 % and 62.5 %, respectively. The differences between carcinoma group and normal tissues group were statistically significant(P

Objective To study the risk factors of nosocomial infections in patients with cerebrovascular disease and prevent and cure them.Methods A retrospective survey on the hospital infeation in patients with cerebrovascular disease in our hospital during March 2003 to March 2005 was couducted.Results The result showed that 61 of the 360 patients had hospital infection,the rate of infection was 16.94%,and the hospital average infection rate in all was 3.92%,hospital infection aging,treatment days in hospital,consciousness invasive operation Hospital infection was a retated.The main infection sites were at respirate tract,the most common bacteria were Gram-Negative bacilli.Conclusions There is higher hospital infection rate among,the acute cerebrvascular patients.Age,the critical patients,invading operations are prmincipal factors.We should prevent it in time.

Objective To explore the diagnosis and treatment for pancreatic cystic neoplasms.Methods The clinical data of 10 cases with pancrestic cystic neoplasms treated from 2004 to 2008 was reviewed and both domestic and internal pertinent literatures were summarized.Results The pancreatic cystic neoplasms mostly happened in middle-aged women.The clinical manifestations showed no specificity.Ultrasonography, CT and MRI could offer important sign for diagnosis.The rate of surgical resection was high and the prognosis was satis-factory.Conclusions The pancreatic cystic neoplasms is being muh with the development of imagings.It is dif-ficuh to distinguish the feature of the cystic neoplasms before surgery, so surgerical resection should be done for all cystic tumors found.

Objective To evaluate the correlation of striatum dopamine transporter (DAT) imaging and the scores of Parkinsonian clinical scale in patients with Parkinson's disease(PD).Methods 99m Tc-TRODAT-1 SPECT imaging was used to assess the DAT binding in the striatums of 29 PD patients, their correlations with the subscales of unified PD rating scale (UPDRS), age and disease duration were also evaluated.Results The scores of subscales of UPDRS II, III and V, as well as the disease duration were negatively correlated with DAT bindings in ipsi-, contra- and bilateral striatum regions (r was -0.70, -0.80, -0.49 and -0.54 respectively, all P

Objective To explore the diagnostic value of MRI on fetal congenital limb deformities.Methods Sixteen pregnant women,aged from 22 to 40 years (average 29 years) and with gestation from 22 to 39 weeks (average 29 weeks) were studied with a 1.5 T superconductive MR unit within 24 to 48 hours after ultrasound studies. Acquisitions consisted of coronal, sagittal, and axial slices relative to the fetal brain, spine, thorax, abdomen, especially limbs using 2D FIESTA sequences. Prenatal US and MR imaging findings were compared with postnatal diagnoses (4 fetuses) or autopsy (12 pregnant women,13 fetuses). Postnatal evaluation included US, MR imaging, computed tomography, and physical examination. Results Of the sixteen pregnant women (15 with a single fetus and 1 with twin fetuses) ,17 fetuses were found. Those limb deformities of sixteen pregnant women included congenital both upper extremities amelia (1 case), sirenomelia sequence (1 case), micmmelia (5 cases, 1 of which were twins),bilateral clenched hands (2 cases), right pelydactyly (1 case), simple right ectrodactyly (1 case), right dactylolysis(1 case), simple club foot (2 cases), hydrocele spinalis with club foot (2 cases), 1 of the 2 cases with bilateral clinodactyly. In 14 of 16 cases, the diagnoses established by MR imaging were correct when compared with postnatal diagnosis, and prenatal MR diagnosis was inaccurate in 2 cases. Conclusion Prenatal MRI is effective in the assessment of congenital limb deformities of fetuses, it can yield information additional to that obtained with US, and further correct US diagnosis.

The hospital information structure, which is made up of various medical business systems, is suffering from the problems of the "information isolated island". Medical business systems in the hospital are mutually isomerous and difficult to become a whole. How to realize the internal barrier-free interaction of the patients effective medical information in the hospital and further to complete the area sharing of patients longitudinal diagnosis and treatment information has become a question having to be solved urgently in the process of healthcare informatization. Based on the HL7 standard, this paper refers to the IHE technical framework, expounds the overall structure of the interaction in the hospital internal and area sharing of medical information with the medical information exchange platform. The paper also gives the details of the whole process of the complete display of the discrete patient health information using Portal technology, which is saved in the business systems in different hospitals. It interacts internally through the information exchange platform and at last stores the information in the regional clinical data repository (CDR).

Conclusions Episodic memory impairment and semantic memory impairment beside the immediat ely recall and naming are the earliest and most pervasive memory deficit in mild AD patients, and episodic memory impairment is more specific than semantic memo ry impairment for the diagnosis of AD.

Objective To investigate the prevention and management of anastomotic leakage in patients with middle and lower rectal cancer after neoadjuvant therapy.Methods In this study,50 cases of middle or lower rectal carcinoma underwent anus preserving radical resection and anastomosis after a 4 cycles of chemotherapy with FOLFOX and 46 Gy(2 Gy×23)radiotherapy.Anastomotic leakage,the prevention and management of this complication were analyzed retrospectively.Results All these 50 patients received low anterior resection after chemoradiotherapy,among the 19 cases receiving prophylactic ileac stoma simultaneously,there was no anastomotic leakage,whereas anastomotic leakage developed in 4 out of the 31 patients who did not receive prophylactic ileac stoma,including concomitant rectovaginal fistula in 2 cases.All these fistulae were cured conservatively.Conclusion Concomitant treatment of FOLFOX regimen and RT in neoadjuvant setting of rectal cancer could increase the rate of anal interior sphincter reservation,prophylactic ileac stoma helps to reduce the rate of anastomotic leakage after a anus-preserving low anterior resection of the cancer.
