Retrograde caudate lobectomy is a proper technique to resect the tumor in caudate lobe when the tumor is too big or closely adherent to the inferior vena cava.A male patient aged 44 years was admitted to the Eastern Hepatobiliary Surgery Hospital in November 2007.The ligaments around the liver were firstly dissected to mobilize the whole liver,and the right hepatic pedicle was dissected and ligated,then the liver was splited anteriorly along the Cantlie's line.The tumor was opposed in the sight and then it was dissected from the liver parenchyma.The short hepatic veins were ligated and the tumor was detached from the inferior vena cava.The inflow blood was occluded for 19 minutes,and the total blood loss was 4500 ml.The technique of retrograde caudate lobectomy can improve the success rate and safety of caudate lobectomy when the tumor in the caudate lobe is too large or adherent to the inferior vena cava.

Objective To investigate the effects of Mailuoning on oxidative stress and ischemic brain injury. Methods A total of 126 healthy male Kunming mice were divided into sham operation (n = 18), normal saline control (n = 54) and Mailuoning (n = 54) groups. A middle cerebral artery occlusion (MCAO) model was induced Two hours after MCAO,Mailuoning injection and equivalent saline were injected via the tail vein in the Mailuoning and normal saline control groups, respectively, and then they were injected every other 24 h.Neurological score was performed, and brain water content, infarct volume, membrane potential,as well as protein oxidative stress metabolites such as 3-nitrotyrosine (3-NT), lipid oxidative stress metabolite 4-hydroxy-2-nonenal (HNE) and nucleic acid oxidative stress metabolite 8-hydroxy-2'-deoxyguanosine (8-OHdG) were detected at 12, 24 and 72 h after MCAO. Results Mailuoning injection could significantly improve the neurological function of cerebral ischemia in mice, decrease brain edema, and reduce infarct volume at different time points after cerebral ischemia Of those, it was most significant at 72 h. Mailuoning injection could reverse the decreased mitochondrial membrane potential in cerebral cortex and internal capsule, and significantly downregulate the increased 3-NT, HNE and 8-OHdG in cerebral cortex, internal capsule and serum after ischemia, of those, the effect of reducing HNE was most significant.Conclusions Mailuoning injection may effectively protect against ischemic brain injury in mice,and its mechanism is associated with inhibiting oxidative stress, particularly anti-lipid oxidation.

Objective To systematically review the efficacy and safety of Jinlian Qingre Effervescent Tablet (JQET) compared to Ribavirin for acute upper respiratory tract infection in children.Methods CNKJ,CBM,WanFang Data,VIP,PubMed,EM base,Web of science,and Cochrane Library databases were searched from the date of establishment to December 2016 for all randomized controlled trials (RCTs) and quasi-RCT on the use of JQET in children with acute respiratory infections.Meta-analysis by using Rev Man 5.3.Results A total of seven RCTs involving 782 patients were included,while the group of JQET involving 392 patients,Ribavirin involving 390 patients.The results ofmeta-analysis indicated that the efficacy in Jinlianqingre group was superior to that of Ribavirin control group,such as clinical effectiveness [RR=l.26,95％CI=(1.18,1.34),P＜0.000 01],fever subsidence time [MD=-1.54,95％CI (-1.79,-1.30),P＜0.000 01],the time of subsided cough [MD=-1.53,95％CI (-1.79,-1.27),P＜0.000 01],the disappearance time of pharyngalgia [MD=-1.29,95％CI (-1.88,-0.70),P＜0.000 1],and Pharyngeal congestion disappearance time [MD=-2.80,95％CI(-3.11,-2.49),P＜0.000 01].The difference was statistically significant.There were three adverse reactions reported in JQET group.Conclusion JQET is superior to the Ribavirin control group in clinical effectiveness,fever subsidence time,time of subsided cough,disappearance time of pharyngalgia,and pharyngeal congestion disappearance time to treat acute upper respiratory tract infection in children.However,these results should be carefully interpreted,and this conclusion has to be further verified by high quality,large scale RCTs.

OBJECTIVE:To evaluate the therapeutic effect of compound glycyrrhizin plus mizolastine for patients with generalized neurodermatitis(GND)and its influence on patietents' psychology.METHODS:60 patients with GND were randomly assigned to receive compound glycyrrhizin plus mizolastine(treatment group)or mizolasitine alone(control group)for 28 days.The psychological factors were examined before and after treatment using self-rating anxiety scale(SAS),and the curative effects and the psychological changes between two groups were compared.RESULTS:The SAS scores of treatment group and control group were 30.53? 1.50 and 33.20? 1.67,respectively(P

Total caudate lobectomy via anterior hepatic transection is still a new technique to resect the tumor in the caudate lobe,which is mastered only by few surgeons.The procedure was successfully performed on a 21-year old patient with focal nodular hyperplasia in caudate lobe.The right and left lobes were first mobilized,then the short hepatic veins were dissected to detach the caudate lobe from the retrohepatic vena cava.Then the liver was split anteriorly and the partial middle lobe was resected.With this process,the tumor was in the sight and we dissected it from the liver parenchyma.The inflow blood was occluded 3 times with a period of 29,27 and 27 minutes,respectively,with an interval of 5 minutes.The total blood loss during operation was 1000 ml.The patient recovered quickly without any complications.The technique for caudate lobectomy via anterior hepatic transection can improve the success rate and safety of caudate lobectomy and deserve clinical consideration.

TBL (Team-based learning) model is a new teaching method.By evaluating the effect of TBL model in theory teaching on Chinese orthodontic postgraduate program in the department of Orthodontics,Guanghua School of Stomatology,Sun Yat-sen University,and comparing the traditional teaching model which centered on teachers,we have probed into the application experience of TBL teaching method in curriculum setting of preclinical theoretic learning in orthodontics postgraduate education.The result shows TBL has significantly enhanced students' enthusiasm for learning,sense of collaboration,and has improved the quality of education.TBL method is better,even though there is something that needs to be improved.
