The effect of traditional therapy is limited for liver cancer,gene therapy gets more and more recognition in recent years.Oncolysis virus is a kind of conditionally replicating virus,with special reproductivity in cancer cells,and then kills them.Gene agents are usually introduced into tumor tissue by intra-tumor and intra-arterial injection,and the technique of interventional therapy is able to satisfy the demand excellently.So,some breakthrough is expected in treating liver cancer by skillfully combining oncolysis virus and interventional technique

In recent years, the number of outpatients in stomatological hospital is in increasing year by year and being accompanied by the corresponding medical risks. One of the risks which may endanger the patient life is medical emergency which need emergency treatment by the dentists in dental clinical practice. The most common emergency type is syncope, followed by hyperventilation, drug overdose, adrenaline reaction and hypertension, etc. Unexpected events mainly occurred at the end of the treatment and before leaving the dental clinic, during or immediately after the local anesthesia, in the treatment process. Tooth extraction related emergency is the most frequently occurring emergency, followed by the local anesthesia related ones. It's strongly suggested that dentists should pay more attention to outpatient clinical emergency treatment, and related knowledge and skills training should be offered to improve the ability to handle medical emergencies.

AIM To investigate the effect of Supplemented Buyang Huanwu Decoction (Astragali Radix,Angelica tail,Paeoniae Radix rubra,etc.) on blood glucose in diabetic rats and its antioxidant activity.METHODS The diabetic rat model induced by streptozotocin (STZ) was established,with metformin as positive control group.After intragastric administration with Supplemented Buyang Huanwu Decoction,the fasting blood glucose,superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in serum and tissues (heart,kidney and pancreas) in rats were detected.HPLC was used to determine the contents of antioxidant constituents (calycosin-7-O-β-D-glucoside and peoniflorin) in plasma,whose pharmacokinetic parameters were then calculated.RESULTS Compared with the model group,the hypoglycemic activity in the Supplemented Buyang Huanwu Decoction group was obvious (P ＜ 0.05),the SOD activity in serum and various issues (except for pancreas) was significantly enhanced,together with significantly reduced MDA level (P ＜ 0.05).The pharmacokinetic behavior of two constituents (calycosin-7-O-3-D-glucoside and peoniflorin) accorded with two-compartment open model,whose blood concentrations reached the highest within 50-70 min,and showed no obvious changes within 180-720 min.CONCLUSION Supplemented Buyang Huanwu Decoction can reduce the blood glucose in diabetic rats and improve the antioxidant activities in heart and kidney.The fast absorption and slow metabolism of calycosin-7-O-3-D-glucoside and peoniflorin in decoction are beneficial to related treatment.

Objective To summarize the experience of interventional catheterization conjoined with cardiac surgical procedures performed in 23 children with congenital heart disease(CHD). Methods 12 cases with residual patent ductus arteriosus after surgical ligation and 2 postoperative cases with severe cyanosis CHD with leftover ventricular septal defect (VSD) received transcatheter closure procedures. 2 children with branch pulmonary stenosis after total correction of tetralogy of Fallot (TOF) received angioplasty and stent placement, respectively. Another postoperative case with aortopulmonary collateral arteries (APCAs) angiorrhexis underwent transcatheter haemostasis. 6 cases underwent interventional catheterization in the preoperative period. 5 cases with transposition of great arteries (TGA) underwent balloon atrial septostomy (BAS) before artery switch procedure and 1 case of TOF underwent APCAs transcatheter occlusion before total correction. Results All cases with residual left to right shunts after surgery were occluded by transcatheter therapy. Interventional catheterization procedure relieved stenosis of branch pulmonary artery in postoperative case with TOF. Haemorrhage was stopped with embolization of ruptured APCAs. Hypoxia and acidosis improved after BAS therapy in 5 cases with TGA and intact ventricular septum and 3 survived from following artery switch procedure while 2 died. The APCAs was transcatheter occluded before TOF total correction. Conclusion Interventional catheterization therapy conjoined with cardiac surgical procedure was an effective and essential method in some postoperative CHD cases and in some of complex cyanosis CHD cases.

Objective To summarize clinical characteristics, diagnosis and surgery of abnormally origination of left coronary artery from the pulmonary artery. Methods Clinical data of 10 patients with left coronary artery abnormally originating from pulmonary artery were analyzed, including 5 men and 5 women, aged from 13 to 40 years. Definite diagnosis was made by ultrasonic cardiogram (UCG) and cardiac catheter examination. Three cases were simply abnormal origination, six cases combined with MI, and one case combined with both MI and ventricular aneurysm of left ventricular apex. Ligation of the abnormal coronary artery was done in four patients, three were given pulmonary artery inner tunnel plasty under extrocorporeal circulation. Open implantation of left coronary artery to ascending aorta were done in 3 patients, while plasty of mitral valve were performed in 5 and ventricular aneurysm resection in 1. Results One patient died postoperatively. The follow-up ranged from 1 month to 11 years. One patient received replacement of mitral valve 16 months after first surgery due to severe MI. All the followed-up patients presented no myocardial ischemia or infarction, no residual shunt or late death. Cardiac function was rehabilitated to grade 1. Conclusion Obvious blood dynamics and cardiovascular morphology changes existed in patients with left coronary artery abnormally originating from pulmonary artery. Early diagnosis and surgery should be done. Proper surgical approach is the key to success.

Objective To study the changes of nitric oxide synthase in placenta during fetal cardiac bypass. Methods Eight pregnant ewes (gestation 120～140 d)were divided equally into control group and bypass group. Bypass group underwent fetal cardiac bypass with centrifugal pump and placenta. Fetal hemodynamic date and blood gas value were recorded before and after bypass. Placenta vascular resistance was calculated. Fetal serum nitric oxide (NO), serum endothlin-1(ET-1) and nitric oxide synthase (NOS) of placenta tissue were assayed. Transcriptions of endothelial NOSmRNA in placental tissue were assayed with RT-PCR technique. Results Acidosis and pressure of oxygen decreased after bypass appeared in fetal lamb of bypass group. Placenta vascular resistance of bypass group elevated significantly (P

Objective To evaluate the outcomes of one-stage repair of aortic coarctation (CoA) and associated cardiac anomalies in infants through a midline sternotomy. Methods Between June 2002 and August 2005, 36 patients (27male, 9 female) underwent surgery for CoA. The age was from 18 days to 8 years[mean (14.3?9.5) months], 27 patients (75%) were younger than 1 year and 18 patients (50%) were younger than 3 months. The body weight was from 3.0 to 23 kg [mean(6.6?3.0)kg]. 27 patients were symptomatic infants and 8 patients were asymptomatic of adults. One patient had recoarctation after repair through a left thracotomy one year ago. The associated cardiac anomalies included ventricular septal defect, patent ductus arteriosus, secundum atrial septal defect, hypoplasia of the aortic arch, transposition of great arteries and subaortic stenosis. 36 cases underwent one-stage operation of extended end-to-end anastomosis through a midline sternotomy. Results One patient died postoperatively with a mortality of 2.8 %. The cause of death was heart and lung function failure. 35 cases were followed up from 4 months to 3 years .One late death occurred. 34 cases were in good condition and no recoarctation. Conclusion Outcomes of one-stage repair of CoA and associated cardiac anomalies in infants through a midline sternotomy is excellent. Technique of extended end -to-end anastomosis may potentially reduce the incidence of recoarctation.

Objective To observe the relationship between blood stasis syndrome and clinical pathology in patients with IgA nephropathy (IgAN). Methods Clinical and pathological materials of 42 patients with blood stasis syndrome,and 73 patients with non blood stasis syndrome were analyzed. Result Patients with blood stasis syndrome are often female and accompanied with renal dysfunction. Compared with patients of non blood stasis syndrome,Lee’s grades were obviously higher,degrees of fibrinogen-related antigen (FRA) deposited in renal were stronger,and scores or ratio of tubular atrophy significantly were higher. Conclusion Blood stasis syndrome of IgAN is correlated with certain renal pathological changes. Blood stasis is the main etiological factor.

[Objective]To probe the probability of autologous platelet-rich glue(PRG) combined with particulate of cancellous bone in treating the aseptic tibial nonunion.[Method]Sixty patients with tibial nonunion in distal 1/3 fragment were randomly divided into 2 groups.Each group had thirty patients.PRG combined with particulate of autogenous cancellous bone was transplanted in the experimental group while particulate of cancellous bone was applied in the control group.The mean time to the operation was 10.5 months(7-36 months) and the average age were 38 years old.The postoperative systemic and local reaction,and X-ray finings of tibial nonunion were observed.The average follow-up was 22 months.According to the Johner-Wruh scoring system the results were statistically analyzed.[Result]At 8 months bony union was all achieved.There was a remarkable difference between those of experimental and control groups.[Conclusion]PRG had an important role in speeding bone healing,and the combination of PRG and particulate of autogenous cancellous bone is an ideal alternative of bone transplantation.
