Methods Virtual print was used in archive computerized medical cases and electronic signature was used to ensure the legality of the archives. Results The system realized the patient-centered medical information integration and raised the level of medical information storage and management significantly. Conclusion The favorable foundation was established fully in the medical cases archiving system, but the system can be improved in future.

Objective To realize the automatic conversion of material management information to branch-level material cost accounting. Methods According to the structure of material management system and cost accounting system, memory procedure of HIS was set to undertake the mission of information conversion. Results Automatic conversion of material management information to branch-level material cost accounting saved a lot of manpower and raised the efficiency and accuracy of cost accounting. Conclusion This solution is worth popularizing not only in other cost accounting but in information system integration and data sharing.

0.05).CD34 showed widespread expression in cholangio-carcinoma tissues,but limited in normal bile duct,which showed significant difference(P

Objective To select the indexes of forensic identification in digital orthopantomogram and formulate the full dentition pattern code.Methods To collect randomly 620 samples with dental interventions and 150 samples with dental pathological changes but without therapy.Then to observe and compare them respectively,select indexes for full dentition patterns according to the dental physiological variations,pathological changes and interventions Finally the diversity of the full dentition patterns in two groups would be evaluated by statistical analysis.Results The group with dental interventions had 619 kinds of dental pattern in 620 samples,its diversity of full dentition patterns was 99.84%.The group with dental pathological changes but without therapy had 146 kinds of dental pattern in 150 samples,thus its diversity of full dentition patterns was 97.33%.Conclusion These full dentition pattern indexes were valuable in the forensic identification of persons with abnormal teeth.

OBJECTIVE To investigate the causes and preventive measures of postoperative pneumonia due to cervical part and upper thoracic part esophageal carcinoma surgery. METHODS Fifty seven cases with cervical part or upper thoracic part esophageal carcinoma from 2001 to 2005 were studied restropectively. RESULTS One patient died of aspiration pneumonia,one died of anastomotic leakage,and three died of adult respiratory distress syndrome(ARDS).The tracheotomy and mechanical ventilation were applied.Pneumonia was confirmed among sixteen patients at different degree. CONCLUSIONS Many causes contribute to postoperative pneumonia on patients with cervical part or thoracic part esophageal carcinoma,and the lesion of recurrent nerve is an important reason.Protection of recurrent nerve may decrease postoperative pneumonia.

Objective To make a plan for the backup of electronic medical records. Methods The background of electronic medical records backup was analyzed, and NTBACKUP tool and batch technology were used to realize the backup plan. Results An automatic-execution backup plan raised the security of electronic medical records greatly. Conclusion The automatic-execution backup plan satisfies the basic demands for medical information security, though there is room for further improvement in data synchronization.

Objective To observe the behavioral effects of acute administration of dizocilpine (MK-801) in rats,and to determine an appropriate doses of the drug to mimicking memory deficits of schizophrenia.Methods 192 rats were randomly divided into model groups and control group,and given different doses of MK-801 or saline.Locomotor activity,pre-pulse inhibition (PPI) test and novel object recognition test were studied respectively.Results The spontaneous activity increased in a dose-dependent manner after the treatment of MK-801.The total distances of locomotor activity in 0.3 mg/kg group((127.04 ± 32.35) m) exhibited a significant difference compared with control group((35.34 ± 12.81) m,P ＜ 0.05).MK-801 decreased PPI in dose-dependent manner(P ＜ 0.01).MK-801 0.1 mg/kg((103.45 ± 68.04) ％) and 0.3 mg/kg ((41.55 ± 62.93) ％) groups showed significant differences compared to control group ((200.39 ± 30.97) ％) in PPI.The discrimination index of 0.03 mg/kg group((15.78 ± 6.23) ％) and 0.1 mg/kg group((22.42 ± 3.85) ％) were lower than that in control group((39.42 ±3.86)％,P＜0.05).Conclusion It is necessary for select right doses for model different endophenotypes of schizophrenia by MK-801.0.03 mg/kg of MK-801 is a relatively appropriate dosage to cause recognition memory damage.

Objective To probe the surgical approach and effect on upper abdominal malignant tumor infiltrating pancrea. Methods Thirty patients with upper abdominal malignant tumor infiltrating pancreas or tissue around pancrea were treated by radical resection on primary tumor combined pancreaticoduodenectomy. Results Three patients died in 1 month after operation due to multiple organ failure. The patients with gallbladder cancer and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 35 months. The patients with gastric antrum carcinoma infiltrating caput pancreatis were followed up averaged 31 months. The patients with recurrent gastric cancer infiltrating caput pancreatis were followed up averaged 13 months. The patients with pancreatic and duodenal invasion by cancer of hepatic flexure of colon were followed up averaged 41 months. The patients with hilar cholangiocarcinoma and metastatic lymph nodes fixed behind caput pancreatis were followed up averaged 11 months. Conclusion The patients with upper abdominal malignant tumor infiltrating pancreas should be operated by radical resection on primary tumor combined pancreaticoduodenectomy, which can increase the rate of tumor resection, and be expected to prolong the survival period.

In recent years, the emergence of single-port laparoscopic technology promoted the development of the technology of laparoscopy, but deficiencies like equipment conflict or lack of triangulation severely hampered the clinical application of this technology. The appearance of single-port laparoscopic flexible instruments makes up for those deficiencies to a great extent. The element is to add a wrist joint to the tip of the instrument to form triangulation and reduce equipment conflict. But this technique is still in an early stage of development. The purpose of this article is to summarize the characteristics and problems of existing flexible single-port laparoscopic instruments, and to provide information for the further improvement, finally the future development was expected.

Background and purpose:Radical nephroureterectomy can be performed in a variety of ways, and each method has its advantages and disadvantages. It still remains controversial for choosing the surgical methods. In this study, we chose six surgical methods and investigated the safety and efficacy of different methods in treating upper urinary tract carcinoma.Methods:We retrospectively analyzed 135 patients with upper urinary tract transitional cell carcinoma who underwent operations in our hospital from Jan. 2002 to Oct. 2013, and compared the data of six different operations in-cluding operating time, volume of bleeding, time of bowel function recovery and incidence of bladder carcinomas.Results:The operations were successfully completed in groups A and B. Five cases in group C were transferred into group A be-cause of failing to pull the nub of the ureter. Two cases in group D were transferred into group A because of failing to pull the nub of the ureter. Three cases in group E were transferred into group D and 1 case was transferred into group A because of adhesion or bleeding. One case in group F was transferred into group A because of bleeding. There was no statistically significant difference in survival rates among six operations.Conclusion:Six operations are all safe and effective for the treatment of upper urinary tract carcinomas. Each method has its advantages and disadvantages. We should choose differ-ent methods according to particular cases.
