Liver cancer is one of the most common malignant tumors in China.The efficacy of traditional treatment for liver cancer is unsatisfactory,and the prognosis of the patients is poor.In recent 10 years,with the development of the molecular biological techniques,genetic therapy has become a new and promising approach for liver cancer.Of which,adenovirus mediated herpes simplex virus thymidine kinase (ADV-tk) for the treatment of liver cancer is widely applied.The enzyme secreted by ADV-tk transformed the prodrug gancyclovir (GCV) to the cytotoxic agents and thus to kill the liver cancer cells.The results of multiple animal and clinical experiments showed that ADV-tk/GCV is effective for the treatment of liver cancer.In this article,the recent progress of ADV-tk/GCV in the treatment of liver cancer was reviewed.

Objective To analyze the effect of different methods of anesthesia maintenance on clinical efficacy and postoperative recovery in elderly patients with gynecological diseases undergoing laparoscopic surgery.Methods A total of 80 elderly patients with gynecological diseases scheduled for laparoscopic surgery were enrolled in this study in our hospital from January 2015 to December 2016.All the patients were randomly divided into two groups of anesthesia maintenance:an intravenous anesthesia alone (n=40) and a combined intravenous and inhaled anesthesia (n =40).The pre-and post-anesthesia changes in arterial blood gas,blood pressure,heart rate and cognitive function,and postoperative complications were analyzed and compared between the two groups.Results There were no significant differences between the two groups in the times of palinesthesia,extubation and talking (all P＞ 0.05).After anesthesia,the levels of arterial blood gas,the blood pressure and the heart rate were relatively stable in both groups,and their differences between the two groups were without statistically significant (all P ＞ 0.05).While,the postoperative cognitive function recovered more rapidly in patients receiving intravenous anesthesia alone for anesthesia maintenance than in those receiving a combined intravenous and inhaled anesthesia,especially at 6 h after extubation.The Mini-mental State Examination (MMSE) score was significantly higher in patients receiving intravenous anesthesia alone (28.8 ± 0.5) than in patients receiving a combined intravenous and inhaled anesthesia (25.1 ±0.6),with statistically significant difference (P＜ 0.05).In addition,there was no statistical difference between the two groups in the incidence of complications.Conclusions As anesthesia maintenance,both an intravenous anesthesia alone and a combined intravenous and inhaled anesthesia can ensure a successfully laparoscopic surgery for gynecological diseases in elderly patients.However,the impact on cognitive function after laparoscopic surgery is smaller in the maintenance of intravenous anesthesia alone than in a combined intravenous and inhaled anesthesia in elderly patients.Intravenous anesthesia alone can be used in elderly patients to receive laparoscopic surgery as routine anesthesia maintenance.

Objective To explore the therapeutic effects of electroacupuncture on regional cerebral blood flow (rCBF) in patients with post-stroke depression. Methods 21 patients with post-stroke depression were randomly divided into electroacupuncture group (n=11) and drug group (n=10). The electroacupuncture group received electroacupuncture on double Hegu (LI4) and Taichong (LR3) once a day for 8 weeks, while the drug group took fluoxetine hydrochloride dispersible tablets 20 mg a day for 8 weeks. They were evaluated with Hamilton Self-rating Scale for Depression (HAMD) before, and 2 weeks, 4 weeks and 8 weeks after treatment respectively. The rCBF were measured with single positron emission computerized tomography (SPECT) before and 8 weeks after treatment. Results The score of HAMD decreased more in the electroacupuncture group than in the drug group 2 weeks after treatment (P<0.05), and there was no significant difference between the two groups 4 and 8 weeks after treatment (P>0.05). The rCBF was significantly greater in the electroacupuncture group than in the drug group. Conclusion That electroacupuncture is effective on post-stroke depression, which may be related with the increase of the rCBF levels.

Objective To investigate the therapeutic effects of acupuncture on pelvic floor muscles and urinary function in patients with spinal cord injury. Methods From March, 2012 to March, 2015, 23 patients with spinal cord injury were divided into control group (n=8), early intervention group (n=8) and later intervention group (n=7). The control group received routine rehabilitation, the intervention groups received acupuncture at Baliao (BL-31, BL-32, BL-33 BL-34), Yanglingquan (GB-34), Sanyinjiao (SP-6) and Taichong (LR-3) acupoints in addition. The early intervention group was acupunctured one week before removal of catheter, and the later intervention group adopted inter-mittent catheterization after removal of catheter, and then received acupuncture. The pelvic floor muscles strength, the urine function and quality of life were recorded before and six weeks after intervention. Results There was no significant difference in all the indices before in-tervention (P>0.05). After intervention, the pelvic floor muscles strength improved in the intervention groups compared with the control group (P<0.05). There was significant difference in the mean frequency of urinary voiding, bladder capacity, time of establishing reflect uri-nation and residual volume of urine after intervention among all the groups (P<0.05), except the mean frequency of urinary voiding and blad-der capacity between the control group and the later intervention group (P>0.05). The quality of life improved in all the groups after inter-vention (F>0.864, P<0.05), however, no significant difference was found among three groups (F=1.558, P<0.05). Conclusion Acupuncture, especially early acupuncture, could improve the pelvic floor muscle strength and bladder function in spinal cord injury patients.

Objective To summarize the clinical results of the surgical treatment for Stanford B aortic dissection patients with proximal aortic aneurysm(including aortic root,ascending,arch) by enblock technique.Methods From Jun.2011 to Oct.2015,20 patients with Stanford type B aortic dissection and proximal aortic aneurysm underwent open surgery by enbloc technique in our center.Among them,there were 15 male and 5 female.Average age of patients was(40.65 ± 13.55) years (range:22-65 years).The comorbidities of proximal aortic diseases are ascending aortic aneurysm in 10,aortic root aneurysm in 8,and aortic arch aneurysm in 2.All the surgeries were accomplished by hypothermic cardiopulmonary bypass assist.The combined surgery includes:extra-anatomy bypass grafting in 16,Bentall procedure in 15,ascending aortic repair in 5.Before surgery and discharged from hospital computed tomography angiography(CTA) was performed in each patient.All patients except 2 were followed.During the follow-up,CTA was performed and recorded.Results The average operation time,cardiopulmonary bypass time,aortic clamping time and selective cerebral perfusion (SCP) time are (6.47 ± 1.01)h (4.5-9 h),(173.60 ± 43.39) min (109-303 min),(91.25 ± 28.63) min (51-165 min),(27.25 ± 6.80) min (17-43 min),respectively.The mean nasopharyngeal temperature during SCP is(23.77 ± 1.27)℃ (21.6-26℃).There were no operative deaths.The mean follow-up time is (32.44 ± 17.27)months (range:8-60 months).Two patients underwent aortic re-intervention during follow-up.And 2 patients were lost follow-up(The follow-up rate is 90％).One late death was found.The patient succumbed to sudden distal aortic rupture.Other patients are survived without any complications.Conclusion Enblock technique is a relatively simple procedure in total aortic arch repair surgery.And it can be a safely surgical treatment for type B aortic dissection patients with proximal aortic aneurysm.The indications of enblock technique for Stanford B aortic dissection patients are those who combined with proximal aortic aneurysm.

Objective:To validate the predictive function of Field Assessment Stroke Triage for Emergency Destination (FAST-ED) score on large vessel occlusion (LVO) in Chinese population.Methods:The information about the patients who had the disease onset within 24 hours, were treated in the Emergency Department of Jinling Hospital, and diagnosed as ‘acute ischemic stroke’ was collected. Via the emergent brain computed tomography angiography or digital subtraction angiography, the patients were divided into LVO group and non-LVO group. The scores of FAST-ED were calculated according to the National Institutes of Health Stroke Scale (NIHSS) scores and compared with Rapid Arterial oCclusion Evaluation (RACE), 3-item Stroke Scale (3I-SS), Cincinnati Stroke Triage Assessment Tool (C-STAT), and Prehospital Acute Stroke Scale (PASS) scores. Moreover, the patients were further divided into anterior and posterior circulation lesion groups to explore whether the FAST-ED scale can differ the anterior or posterior circulation effectively.Results:Three hundred and eighty-one patients were eventually included, among whom 284 were diagnosed as LVO, and 97 were diagnosed as non-LVO. Receiver operating characteristic curves showed that cut-off value of 4 optimized the scale (sensitivity: 0.76, specificity: 0.69, area under the curve: 0.78). The area under the curve of FAST-ED score(0.78) showed no statistically significant difference with NIHSS (0.79), RACE (0.77), 3I-SS (0.78) and C-STAT scores (0.75), and exhibited statistically significant difference with PASS score (0.74; 95% CI 0.69-0.78, P=0.01). FAST-ED score showed no statistically significant difference in predicting anterior and posterior circulation lesions. Conclusions:FAST-ED score can predict LVO in a rather accurate manner. It can predict anterior and posterior circulation lesions with similar effectiveness. So FAST-ED is able to be a prehospital screening tool and make assistance to the prehospital treatment.
