Objective To improve the method for the Word-Stock file update and cancel the Disk P mapping in order to meet the requirements of HIS such as Out-Patient Doctor Workstation system and Nurse system.Methods Two tables were created to store the names,contents and update time of the dictionary,and the word-stock file was built through searching the data of the tables.Results The word-stock file update was improved successfully.Conclusion The new method for the word-stock file update is easy to be achieved so that the program of client can update immediately,which also can get rid of the error and hidden troubles.

Objective To analyse the MRI characteristics of the chronic clicking temporomandibular joints(TMJs).Methods 20 TMJs in 10 young chronic clicking individuals (12 clicking TMJs)and 60 TMJs in 30 young healthy volunteers were examined by MRI scanner, and sagittal oblique opened-mouth and closed-mouth position images were observed.Then comparing the MRI findings of the acquired j oints between two groups.Results The ratio of the non-double concave articular disc,slightly high signal intensity in the articular disc, abnormal changes of the condyle,articular fluid,anterior displacement of the articular disc,and increasedDraceangles in the clicking group were significantly higher than those in the control group(P<0.05).The result revealed statistically significant differences.Conclusion The MRI anatomical characteristics can be an indicator for the TMJ anomalys,and provide an obj ective radiological basis for clinical diagnosis and treatment to some extent.

Purpose: To evaluate the efficacy and adverse effects of letrozole for postmenopausal breast cancer patients with bone raetastases. Methods: Thity-six breast cancer patients with bone metstases received 2. 5 mg tablet letrozole every day. for at least two months. Results: In the 36 patients who were evaluable for efficacy and toxicity, the complete response rate (CR) , partial response rate ( PR) , disease stabilization rate ( SD) and progressive disease rate ( PD) were respectively 5.5% , 22. 2% , 55. 5% and 16. 6% . The clinical benefit rate ( CR + PR + SD ≥ 6 months ) was 58. 3% (21/36) with 11 patients (30. 5%) having SD for at least 6 months . Conclusions: Letrozole is a well tolerated agent with reasonable efficacy but low toxicity for postmenopausal breast cancer patients with bone metastases.

Objective To evaluate the surgical results of off-pump for plication for left ventricular aneurysm. Methods The study included 34 patients with left ventricular aneurysm,who underwent left ventricular aneurysmecto- my and plicatien on pump in group Ⅰ(17 cases)and simply aneurysm plicatien off pump in group Ⅱ(17 cases).All patients except two in group I underwent coronary artery bypass grafting simultaneously.Results There was one early death in group Ⅱ because of refractory ventricular arrhythmia.The complication included atrial fibrillation,ventricular arrhythmias,heart failure and delayed healing of wound.The aneurysm in group Ⅰ[(45?15)%of the ventricle]is larger than in groupⅡ[(29?12)%of the ventricle,P

Objective To explore the nutrition condition improvement function of Jianpihuazhuoshengxue mixture to the long-term maintenance hemodialysis patient. Methods Before the treatment, to determine the nutrition condition of 43 cases dialysis patient that are divided to treatment group and control group. The two groups are all dialyze, the treatment group are added of Jianpihuazhuoshengxue mixture. To measure nutrition condition of the two groups again after one treatment course. Results and Conclusion Jianpihuazhuoshengxue mixture can remarkably raise the dialysis patient's nutritional level, especially the plasma albumin level. Possibly the mixture improvement the nutrition condition of dialysis patient mainly through raising the plasma albumin level, thus improve quality of life of the dialysis patient.

Objective To study the effects of dexamethasone (DEX), recombinant bone morphogenetic protein-2 (rhBMP2), and combined application of rhBMP2 and DEX on alkaline phosphatase (ALP) activity of human dental pulp cells (HDPCs) in vitro. Methods HDPCs were cultured by tissue block method and identified. Effects of DEX, rhBMP2, and combined application of both on ALP activity of HDPCs were determined by a modified enzyme dynamical method. Results DEX could enhance ALP activity, reaching the peak value at the concentration of 0.01 nmol/ml. rhBMP2 could enhance ALP activity in a dose-dependent manner. ALP activity was significantly higher under the condition of combined application of DEX and rhBMP2 than single application of DEX or rhBMP2 only. Conclusion Both DEX and rhBMP2 can enhance ALP activity of HDPCs. However, combined application of DEX and rhBMP2 can greatly enhance ALP activity of HDPCs.

Objective To evaluate the surgical technique and clinical application of retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy with no suture of the incision. Methods Twenty-five patients who had upper urinary tract calculi with the course from 10 months to 6 years were enrolled.The size of the calculi was 1.2 to 3.1 cm in diameter.ESWL was ineffecative in 14 of the patients and ureteroscopic lithotomy failed in 2 of them.Then the 25 patients underwent retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy.Details of the procedure were presented. Results All the operations were successful in the 25 patients. The operations took 60 to 190 min with a mean time of 105 min.All the patients fully recovered with no complication observed during the 9～12 months' follow-up. Conclusions Retroperitoneal laparoscopy surgery with no suture of the incision has advantages of minimal invasive,safe,effective and rapid postoperative rehabilitation.The surgical procedure has a good prospect in the urologic clinical practice.
