Perihilar surgery is full of challenge,risk,variability and uncertainty.Because of the anatomic variability,the pathophysiological complexity and invasion of the diseases,hepatic hilar biliary surgery has the characteristics of high operative difficulties,low resection rate,easy intraoperative bleeding,more postoperative complications,high recurrence rate and mortality rate.The cure rate and safety of the operation can be improved only through comprehensive imaging examinations and preoperative evaluation of liver function as well as the correct use of surgical techniques of anatomic paths,lesions excision and hepatic hilar reconstruction.The core of perihilar surgical techniques is hepatic hilar anatomy and explosion,including hilar plate dissection,dissection of liver along the medial fissure,quadrate lobe of liver resection and perihilar resection.Perihilar surgery is a comprehensive technique involving preoperative,intraoperative and postoperative procedures.The cure rates of perihilar biliary diseases can be improved by a combination of enhanced recovery after surgery and optimized and individualized surgical plans for patients.

Objective To explore the effects of different concentrations of propofol postconditioning against glutamate neurotoxicity to brain slices of neonatal rats.Methods The brain slices of neonatal rats were prepared and cultured in complete medium.They were randomly divided into five groups:the normal control group,glutamate injury group(RI group),1 mg/L propofol postconditioning group(PL1+RI group),3 mg/L propofol postconditioning group(PL3+RI group),5 mg/L propofol postconditioning group(PL5+RI group),12 cases in each group.The RI,PL1+RI,PL3+RI,PL5+RI groups were cultured for 6 days,then the brain slices were moved into the culture medium containing glutamate(1 mmol/L) and incubated for 30 minutes.And then,respectively,the brain slices of RI group were put into another complete culture medium,the PL1+RI group,PL3+RI group and PL5+RI group were put into the medium containing corresponding concentrations of propofol medium and long chain fat emulsion injection.All of the above were cultured for 24 hours in order to establish the injury model.The numbers of the Nissl body,the LDH release rates and the brain tissue damage rates of each brain slice were detected to evaluate the effects of propofol postconditioning on the reperfusion injury in the glutamate-damaged brain slices of neonatal rats.Results Compared with the RI group,the numbers of the Nissl body of the PL1+RI group,PL3+RI group and PL5+RI were higher,the LDH release rates and the brain tissue damage rates of the PL1+RI group,PL3+RI group and PL5+RI were lower,the diferences were significant(P<0.05).Among the three PL+RI groups,the LDH release rates and the brain tissue damage rates of the PL3+RI group were lower than those of the other two groups,the diferences were significant(P<0.05),at the same time,the numbers of Nissl body were more than the other two groups,the diferences were significant(P<0.05).Conclusion Propofol postconditioning has protective effects on the reperfusion injury in the glutamate-damaged brain slices of neonatal rats.However,the protective effects are not dose-dependent,and 3 μg/mL is the best dose of propofol to keep the glutamate-damaged brain slices from reperfusion injury in this research.

Objective To compare the clinical features and treatment between elderly onset rheumatoid arthritis(EORA)and young onset rheumatoid arthritis(YORA).Methods The EORA patients (n=60)and the YORA patients (n =90)were compared regarding sex ratio,activity of pathogenetic condition,disease severity,extra-articular manifestations,complications,laboratory indexes,and therapeutic schedules.Results The female/male ratio was 36/24(1.50 ∶ 1.0)in group EORA,and 69/21(3.3 ∶ 1.0)in group YORA,with higher female/male ratio in in group YORA.The frequency of morning stiffness,proximal interphalangeal joint involvement and metacarpophalangeal joint involvement were lower in group EORA(53.3 ％,46.676％ and 61.67 ％) than in group YORA (72.2 ％,77.8 ％,81.11％) (x2 =5.521,15.385,6.960,P =0.018,0.000,0.008 respectively).Large joints involvement at onset of rheumatoid arthritis was higher in group EORA(38.33 ％)than in group YORA(18.89 ％)(x2=6.960,P=0.008).The joint swollen and tender counts were comparatively less (16.51 ± 7.34) and (15.92 ± 8.44) in group EORA than in group YORA(22.46 ± 7.58) and (23.8 ± 8.93) (t =5.080、5.740,all P =0.000) respectively.The accumulated disease activity score(DAS28)was higher in group EORA(5.86± 1.57)than in YORA(4.92± 1.64) (t=3.360,P =0.001).HAQ score was lower in group EORA(0.83 ± 0.85)than in group YORA (1.16±0.91) (t=2.43,P =0.02).Comorbid conditions such as osteoarthritis,osteoporosis,cardiovascular disease and chronic renal insufficiency were more frequent in group EORA (51.7 ％,31.7 ％,18.3 ％ and 15.00％)than in group YORA(27.8％,15.6％,5.6％ and 4.4％)(x2 =11.722,5.445,6.168,5.067,P=0.001,0.020,0.013,0.024).The positive rate of RF were more higher in YORA(70.00％)than in group EORA (48.33％)(x2 =7.126 P=0.008).The synthetic or biologic traditional DMARDs (disease modifying antirheumatic drugs)were widely used in group YORA(78.9％ and 31.1％)than in group EORA(40.0％ and 10.0％)(x2 =14.940,9.153,P =0.000,0.002).The more frequently used program with glucocorticoids hormonal therapy was received in group EORA(38.3 ％)than in group YORA(20.00 ％)(x2 =6.092 P=0.014) Conclusions EORA patients differs from YORA patients in many of ways,including a more balanced gender distribution,atypical presentation at onset of disease,more frequent involvement of large joints,seronegativity in a higher percentage,and less frequent positivity of anti CCP-antibody,which makes diagnosis more difficult in the earlier period.Therapy of EORA with DMARDs should be instituted based on disease activity,if there is no contraindication.

Persistent infection of hepatitis C virus (HCV) remains as a worldwide threat to public health,which involves a complex interaction between virus- and host related factors.HCV is classified as six genotypes and many subtypes according to the sequence heterogenecity.HCV genotype should be determined prior to treatment initiation since it plays a key role in selection of therapeutic regimen for chronic hepatitis C.Development of the antiviral treatment with protease inhibitor in combination with pegylated IFN-α and ribavirin requires the accurate determination of subtypes,e.g. 1a and 1b,as well.Genotyping methods based onsequenceanalysis, reversehybridizationorreal-timePCRhavebeendevelopedand evaluated.Some issues,however,should be settled to standardize the utility and result interpretation of these methods.More recently,host genotypes of IL28B have been found to be closely associated with HCV spontaneous clearance and the response to antiviral therapy.Moreover,polymorphisms in inosine triphosphate pyrophosphatase gene affect ribavirin-induced anemia.Therefore, host genotyping will be beneficial in predicting the outcome of chronic hepatitis C and monitoring the drug-induced adverse events.

Objective To explore the effect of eletroacupuncture (EA) on angiogenesis after cerebral ischemia and reperfusion through observing the number of peripheral blood endothelial progenitor cells (EPCs) and the expression of vascular endothelial growth factor (VEGF) in the hippocampus.Methods Among 50 male Sprague-Dawley (SD) rats,10 were randomly selected as a control group (CG).Qi deficiency and blood stasis were induced in the other 40 rats by intragastric administration of dahuang daily for 7 days.A model of focal cerebral ischemia and reperfusion injury was then created by thread-occlusion of the middle cerebral artery,except in 10 rats selected for the sham operation group (SOG) who received the same operation without tightening the thread.The successfully modeled rats were divided into a model group (MG,n =10) and an electroacupuncture group (EAG,n =10).The rats in EAG started acupuncture treatment the next day after modeling,while no treatment was given to those in the other groups.On day 1,3 and 7 after the modeling,the neurological functioning of the 4 groups was assessed using Basso-Beattie-Bresnahan locomotion scoring and the number of EPCs in the peripheral circulation was detected by flow cytometry.On the 8th day,all the rats were decapitated and the VEGF expression was detected immunohistochemically.Results The average BBB locomotion score of the EAG rose significantly from (4.50 ± 1.05) on day 1,to (13.67 ± 1.21) on day 3,and then further to (20.00 ±0.89) by day 7,significantly higher than that of MG at the same time points,but still significantly lower than that of the control group.The average number of EPCs in the peripheral circulation in the MG also increased from (26.83 ± 6.05) on day 1 to (33.67 ± 5.39) on day 3,and decreased to (32.83 ± 5.04) on day 7 after modeling,significantly lower than that of the CG [(45.50 ±9.40),(42.17 ±4.62) and (41.33 ±5.50)],the SOG [(58.00 ±8.05),(59.67±4.84) and (53.83 ±5.38)[and the EAG [(66.17 ±4.36),(127.50 ±73.75) and (55.00 ±35.15)] at each time point.After occlusion,the average expression of VEGF-positive cells in the hippocampus of the EAG [(27.80 ± 2.39)％] was significantly higher than that of the MG,and both were significantly higher than that of the CG.Conclusions Eletroacupuncture can up-regulate VEGF expression and EPCs in the peripheral blood in rats after cerebral ischemia-reperfusion,which can promote angiogenesis and neural functional recovery.
