Objective To study the neuroprotective effect of sevoflurane on controlled hypotension in patients with coronary heart disease undergoing craniocerebral surgery. Methods Twenty-six patients with coronary heart disease undergoing craniocerebral surgery were randomly divided into two groups,receiving either inhaled 2%-5%sevoflurane plus intravenous sodium nitroprusside (treatment group,n=13) or intravenous sodium nitroprusside 3-8 μg·kg-1 alone (contorl group,n=13) for blood pressure control. The hemodynamic changes were recorded during the operation. Patient satisfaction with surgeons and the duration hospital stay after surgery were recorded. The levels of cardiac troponin I (TNI),creatine kinase-MB (CK-MBM),neuron specific enolase ( NSE) and S100 calcium binding proteinβ( S-100βprotein) in serum were detected at one day pre-operation,the end of the operation,and one day post-operation. Results The duration of hospital stay after surgery was significantly shortened in treatment group [(20. 3±3. 8) versus (23. 9±4. 6) d,P<0. 05) compared with control group. The average heart rate significantly decreased, patient satisfaction significantly increased, and serum levels of NSE and S-100β protein one day post-operation significantly decreased as compared to control group (all P<0. 05). Compared with the day before operation,serum levels of NSE and S-100βprotein in the two groups increased significantly at the end of surgery (P<0. 05),and the levels of TNI,CK-MBM,NSE and S-100βsignificantly elevated one day post-operation (P<0. 05). Compared with the end of operation,serum levels of NSE and S-100βin contorl group incarcerated remarkably (P<0. 05) Conclusion Sevoflurane plays an important neuroprotective role,as evidenced by improving patients' satisfaction,reducing hospital stay after surgery,and maintaining the balance of myocardial oxygen delivery and consumption in craniocerebral surgery patients with coronary heart disease during controlled hypotension. However,it can not prevent postoperative myocardial injury in these patients.

Objective:To investigate the possibility and feasibility of the simultaneous coronary artery bypass grafting (CABG) with tumor excision in patients suffering from tumor combined with coronary artery disease(CAD). Methods:From August 2000 to July 2006, ten patients who were suspected of tumor (four patients suffered from urinary system tumor, two digestive system tumor, and four pulmonary tumor) with coronary artery disease were successfully treated by simultaneous surgeries. Surgical incisions were chose by the different tumor position. All carried on the CABG before tumor excision except one case. The two cases had cardiopulmonary bypass CABG, the rest eight had off-pump CABG. Follow-up was conducted after operation. Results:The combined operations were satisfied. There was no in-hospital mortality, no postoperative hemorrhage, no myocardial ischemia or infarction, with few complications. Postoperative in-hospital stay was 10-34 days, average 22.4 days. All discharged in cure. One patient lost the follow-up. Nine patients were followed up from six months to seven years three months. Two patients died from metastasis, and the others survived with satisfied follow-up without cardiovascular events. Conclusion:The simultaneous coronary artery bypass grafting with tumor excision for patients who suffer from either CAD with benign or malignant tumor is safe and feasible with satisfied short-and long-term survival.

Indirect fluorescent antibody test (IFAT) using frozen sections of Brugia malayi adult worms as antigen was employed in the diagnosis and epidemiological investigation of human filariasis. Sera were collected from 704 cases with bancroftian or malayan microfilaremia. the positive rate was 92.8-99.1%. Of 150 healthy people from non-endemic areas, only one showed a positive reaction (false positive rate 0.7%) (Table 1). This technique proved to be highly sensitive and specific for the diagnosis of filariasis and the antigen is easy to prepare. It might be used in sero-epidemiological investigation for the assessment of filariasis control.

Objective To study the characteristics of its pathologic and neurophysiologic changes of a ani-mal model of cervical spinal cord compression, and to explore the relationship between the severity of spinal cord inju-ry and its functions. Methods Thirty-two rabbits were divided into 4 groups randomly. A catheter was inserted intothe vertebral canal and a balloon was inflated to compress spinal cord in epidural space. According to the diameter ofballoon, the animals were divided into 4 groups (A, B, C, D group), Each group consisted of 8 rabbits. The corti-cal somatosensory evoked potential (CSEP) and motor evoked potential (MEP) were used to assess neurologicalfunction. Motor function behavior was scored before and on 1, 3, 7 and 14 days after surgery. Histological observa-tions were performed, pathological changes were observed by light and electron microscope. Results Spinal cordcompression resulted in a gradual increase of the peak latency and significant decrease of the peak amplitude. The la-tency and amplitude of MEP were changed more dramatically than those of CSEP. The result indicated that MEP wasmore sensitive than CSEP to the compression. Analysis also revealed that the severer the pathologic changes, the lon-ger the latency and the lower the amplitude of the evoked potentials. Conclusion The animal model presented inthis paper was simple and standardized. Evoked potentials as a noninvasive technique have great value in monitoringspinal cord function. The variance of amplitude and the latency in significantly correlate with the degree of compres-sion of the spinal cord.

Objective To investigate the characteristic of 13C-methacetin breath test (13C-MBT) as a tool to monitor the hepatic function of patients with hepatic carcinoma by comparing with Child-Pugh classification and general liver function. Methods Thirty-nine patients with primary liver cancer, 16 patients with hepatic metastasis and 14 healthy volunteers serving as controls were included in this study. According to Child-Pugh classification, the primary liver cancer patients were divided into A, B and C subgroups. All subjects received 13C-MBT and routine liver function tests after an overnight fast. The three major parameters of 13C-MBT i.e. maximum excretion rate before 40 min (Mwnax40), 13CO2 cumulative excretion of 40 min(CUM40) and that of 120 min(CUM120) were recorded and the two metabolism curves (DOB curve, MV curve) were made. Results (1) In the control, hepatic metastasis and primary liver cancer groups, both the DOB curve and MV curve were similar in shape; the peak time occurred at about 20 min after administration and then the curves lowered progressively. There were significant differences between the primary liver cancer group and the other two groups, but it was not statistically different between the hepatic metastasis group and the controls. The shape was obviously distinct in the groups A, B and C of primary liver cancer. The group A had a single sharp peak curve, group B a relatively flat peak curve with a lower level for a long time after the ascending phase and group C no clear excretion peak or even a negative curve. (2) As to the three parameters of 13C-MBT, there were statistical difference between the primary liver cancer group and the other two groups(P <0. 05). Between hepatic metastasis group and controls,there was statistical difference about CUM120 (P <0. 05), but no statistical difference about Mvmax40 and CUM40. While in the three groups with primary liver cancer groups, there was statistical difference between group A and B in Mvmax40 and CUM40 ( P < 0. 05 ), but no statistical difference between group B and C. As to CUM120, there was statistical difference only between group A and C. (3) Comparing the three parameters of 13C-MBT with routine liver function tests, there was negative correlation with TBA, positive correlation with Alb, PA, ChE and no correlation with ALT, AST, TBil, γ-GT, ALP and PT. (4) There was a good consistency between 13C-MBT and Child-Pugh classification in the evaluation of liver function of patients with liver cancer ( Kappa = 0. 647, P < 0. 05 ). Conclusion The value of the three parameters of 13C-MBT is decreased with severity of the liver disease and 13C-MBT may be used to evaluate the reserved hepatic function in patients with primary liver cancer with a diagnostic value equivalent to Child-Pugh classification. The study further confirms that 13C-MBT has correlation with TBA,AIb, PA and ChE.
