18 cases of atlanto-axial instability with symptoms of spinal cord compression were treated operati-vely. The reasons of instability were congenital deformity of great occipital foramen region with atlanto-axial subluxation in 7, atlantoaxial tuberculosis complicated with dislocation in 4, traumatic atlanto-axial dislocation in 5, and spontaneous dislocation of atlanto-axial joint in 2. Cranial traction was instituted preoperatively in most cases. The operations were done under local anesthesia. Open reduction of atlas, and fixation by wiring and fusion of atlanto-axial laminae with bone graft were performed in 8 cases, and occipto-cervical fusion by bone grafting with or without decompression of great occiptal foramen in 10 cases. Postoperative plaster bed or heas chest cast was stressed. All cases but one were successful, the dislocation was reduced, symptoms of spinal cord compression were relieved, the fusion was solid, and most of them returned to work.

In order to make early diagnosis of the ischemic heart disease in the aged NIDDM patients. 500 patients underwent a series of examinations including maximal plate exercise with 59M Tc-MIBI ECT myocardiography. maximal plate exercise ECG and 24-hour ambulatory ECG. The serum lipid. glucose and insulin levels, daily urine protein, glomerular filtration rate,body weight index and eyeground were also studied. The results showed that 56 patients had obvious myocardial ischemia (group A),49 patients had slight myocardial ischemia (group B)and 395 patients were free from myocardial ischemia (group C). With positive 59MTc-MIBI ECT myocardiography, 15 among 16 patients in group A and 6 among 12 patients in group B and none among 5 in group C showed coronary artery narrowing in coronary radiography. The average course of DM,serum total cholesterol,fasting serum glucose and insulin, glucosylated hemoglobin.daily urine protein and the incidence of proliferative retinopathy of group A were higher than those of group B or C(P

Objective To study the effect of individual and environmental factors of diabeties on their glycemic and lipidic metabolism. Methods While educating diabeties with diabetic informations, we inguired their individual data questionnaires. According to their diabetic periods,cultural levels,compliance to their doctors,daily work times and ocupations respectively,we grouped these patients and compared their fasting and postprandial glycemia (FBG & PBG), GHb,serum lipids and serum uric acid (BUA). Results Among 2 856 diabetic patients,the type I was about 4. 9% and the type Ⅱ about 95. 1% ; the family patients was about 9. 91% and the overweight about 44. 29K. According to patients' compliance to their doctors,blood glucose,GHb and lipids and BUA was lower in absolute compliance group than the basical group or the non compliance one (P＜0. 02),and the levels of glycemia and GHb and TG all related to their compliance (respectively r=- 0. 059, - 0. 055, - 0. 075, - 0. 063 ; and P＜0. 05, 0. 05, 0. 01, 0. 025 ). Considering the diabetes periods,the 1-5 year metabolic control of group was best (P＜0. 02) and the 5- 10 year and above 10 year metabolic control groups were better than the group within one year (P ＜0. 05). To patients' cultural levels, the metabolic control senior or higher middle school groups was better than the junior middle school or lower (P＜0. 05). Thinking their daily work time and occupation,the metabolic control of groups working more than seven hours was worst (p respectively less than 0. 05 and 0. 02). Conclusion diabetic patients' individual and environmental factors are all affecting their metabolic control,among them the complicance is most effective.

In order to make the best of the medical equipment and avoid repetitive purchase,our hospital establishes a medical equipment communion-center,the section offices of which are responsible for keeping the occasionally-used but indispensable equipment.The equipment managed by the Medical Affairs Office and the Medical Engineering Office could be lent to any section offices in the hospital,thus not only facilitating medical treatment but reducing expenses.

In new era,field medical equipment gives full scope to the development of medical equipment and fulfillment of daily operation.Meanwhile,to meet the requirements of military reform,basic sanitation service needs to grasp characteristics of medical equipment and to improve management capability of medical equipment.

By analyzing the role of shared equipment in the share center of medical equipment, key factors in managing the share center are pointed out. According to the practice and experience in hospital, measures of giving full play to shared equipment are discussed from many aspects which include proper keeping, moderate collocating, concrete exchanging, popular training, timely repairing and precise checking, etc.

Objective To introduce database information query and its printing technology with the Sql Sever 2000 software based on the VC++6.0 software. Methods The data query from the sql Sever 2000 database made use of ADO technology of VC++6.0 and implemented the print and print preview via append document and view frame in the procedure of the dialog box. Results The data query from Sql Sever 2000 database was implemented and the queried data was printed. Conclusion It offers one printing method in the dialog box procedure.

Objective Target-controlIed-infusion(TCI) system makes administration of intravenous anesthetics simpler, more accurate and adjustable. Bispectral index (BIS) is generally accepted as a measurement of depth of sedation and anesthesia. The aim of this study was to evaluate the usefulness of BIS as a feedback control in propofol anesthesia with TCI for patients undergoing laparoscopic cholecystectomy. Methods Forty ASA Ⅰ - Ⅱ patients (12 male, 28 female) aged between 20-70 yr were randomly allocated to one of two groups of twenty each: feedback TCI group and TCI group. In feedback TCI group, BIS value of 50 was set as the control variable. A bolus of 3 ?g?kg-1 fentanyl was given Ⅳ 3 min before induction. The target concentration of propofol was set at 3 ?g?ml-1 throughout anesthesia. Real time BIS, the highest and lowest systolic and diastolic pressure during operation, doses of adjunctive drugs, time for emergence and orientation, awareness during operation and the standardized unit dose of propofol were recorded and compared between groups. Results Total dose of propofol was statistically lower in the feedback TCI group than that in TCI group(P

ObjectiveTo determine the bispectral index and dose of propofol at which 50 % of patients fall into unconsciousness during induction (BIS50 and EDs0 ). MethodsThirty unpremedicated ASA Ⅰ-Ⅱ patients scheduled for elective surgery were included in this study. The patients did not take any sedatives or hypnotics and had no psychiatric disease. Loss of consciousness and changes in BIS during induction with propofol were studied by sequential experimental method. The loss of responses to verbal command and eyelash stimulation was used as an induction of unconsciousness. The data obtained were analyzed by linear regression and calculated to determine BIS50 and ED50 using weighted averaging method. ResultsThe BIS50 and ED50 for propofol were 79.17 and 1.0192 ng/kg with the 95％ confidence intervals of 72.08-88.55 and 0.94-1.148 mg/kg respectively. Conclusions The sequential experimental method for determination of ED50 is simple, efficient and reliable and also suitable for determination of BIS50.

Objective To compare the effects of target-controlled infusion (TCI) of remifentanil (R) in various doses in combination of TCI propofol (P) on hemodynamic response to tracheal intubation. Methods Fifty ASA Ⅰ - Ⅱ patients (18 male, 32 female) aged 100 bpm) . The TCI system comprised Graseby 3500 infusion pump controlled by computer program Rugloop which included Marsh and Minto pharmacokinetic parameters. Results Induction time (from start of TCI R + P to LOC) was significantly longer in group RO and R2 than that in group R4, R6 and R8 ( P
