Fast tract surgery (FTS) has been implemented in different fields of surgery to attenuate the surgical stress response and accelerate recovery.Liver resection is the preferred treatment for a variety of primary and secondary liver tumors.However,liver resection is associated with severe stress response and higher rate of postoperative morbidity and mortality.Fast tract surgery has been reported to accelerate recovery following liver resection.In this review,we summarize the recent progress of fast tract surgery in liver resection.

Epmedii Folium is a commonly used traditional Chinese drug, and is beneficial for the "liver" and "kidney" s function in Chinese medicine. Recently, the origin of this drug is more complex. Most of the identification studies are emphasized on the species certified by the pharmacopoeia and other related species from the same genus of Epimedium, but few was emphasized on the counterfeit. In this paper, one counterfeit of Epmedii Folium, identified as the dried leaf of Quercus variabilis (Fam. Fagaceae), has been reported based on field investigation, comparing specimen of Epmedii Folium and Q. variabilis,using the macroscopic, microscopic and TmC methods. It is resulted that they could be identified clearly not only by the macroscopic features, such as the vein character and the tooth apex, but also by the microscopic features, such as the vascular bundles of the midrib, the non-glandular hair, the anticlinal wall of the epidermis cell and the calcium oxalate crystal. Furthermore their TLC chromatograms showed also difference. This study will give reference for the identification of Epmedii Folium and the related supervision and inspection work.

Objective To investigate the virological response in hepatitis C virus (HCV)genotype 1b relapsers after 48 weeks of peginterferon/ribavirin (peg-IFN/RBV)combination retreatment,and to explore the predictive value of interleukin (IL )-28B rs12978960 genetic polymorphismon virological response.Methods From 2012 to 2014,genotype 1b chronic hepatitis C (CHC)relapsers in He′nan Provincial People′s Hospital were retreated with combined peg-IFN/RBV for 48 weeks and followed up for 24 weeks off-treatment.Host IL-28B genetic polymorphism was detected.Predictive factors associated with virological response and sustained virological response (SVR)were analyzed.Independent-samples t test was conducted in continuous variables,whileχ2 test or Fisher exact probability test was conducted in counts data.Results A total of 61 patients finished 48 weeks of peg-IFN/RBV combination therapy and were further followed up for 24 weeks off-treatment.Mean age was (46.7 ±12.4)years.Thirty-seven patients (60.7%)were male and 49 were rs12978960 CC genotype.After 48 weeks of retreatment with peg-IFN/RBV and 24 weeks of off-treatment follow-up,40 patients (65 .6%)achieved SVR.Rapid virological response (RVR)and SVR of younger patients were both significantly higher than those of older patients (100.0% vs 67.4% and 85 .0% vs 47.6%,respectively;both P =0.006).IL-28B rs12978960 genotype was predictive to RVR and SVR.Patients with RVR and SVR had higher carriage rates of IL-28B rs12978960 CC genotype compared with those without RVR and SVR (both P <0.05 ).Patients with CC genotype had higher rates of RVR (34.1 % vs 0;χ2 = 10.625 ,P =0.006 ),end-of-treatment virological response (84.1 % vs 70.6%;χ2 =5 .563,P =0.039 )and SVR (77.3% vs 35 .3%;χ2 =9.572,P =0.007)than those with CT/TT genotype.However,there were no statistical differences of extended RVR (34.1 % vs 29.4%;χ2 =0.122,P =0.809)and early virological response (79.5 % vs 82.3%;χ2 =0.612,P =0.964).Conclusions Retreatment with antiviral therapy is necessary in CHC patients with genotype 1b. IL-28B rs12978960 genetic polymorphism is predictive to the SVR of retreatment,especially for patients without RVR,which will provide individualized treatment and optimize the treatment strategy.

Objective To analyze the bloodstream infections caused by vancomycin‐resistant Enterococcus (VRE)in West China Hospital and examine the risk factors of such infections for best control of VRE infections .Methods Case‐control method was used to compare the bloodstream infections due to VRE with those caused by vancomycin‐susceptible Enterococcus(VSE)from August 2010 to August 2014 in West China Hospital .The data were compared by T‐test ,Chi‐square test (univariate analysis) and logistic regression analysis (multivariate analysis) using SPSS 19 .0 software .Results A total of 31 VRE strains were isolated from bloodstream infections in the study period ,including 5 (16 .1 % ) strains of vancomycin‐resistant Enterococcus faecalis and 26 (83 .9 % )strains of vancomycin‐resistant Enterococcus faecium .In the past four years ,the prevalence of vancomycin‐resistant E . f aecalis in bloodstream infections was 1 .5% ,1 .6% ,1 .8% ,and 1 .2% ;while the prevalence of vancomycin‐resistant E . f aecium in bloodstream infections was 3 .8% ,4 .4% ,5 .8% ,and 7 .1% .Such VRE bloodstream infection was mainly found in Intensive Care Unit (ICU)(13 ,41 .9% )and Department of Neurosurgery (4 ,12 .9% ) .More than 90% of the isolates were resistant to ampicillin and erythromycin .But less than 20% of the strains were resistant to quinupristin‐dalfopristin and linezolid . Univariate analysis indicated that prolonged hospital stay , ICU admission , venous catheter ,prior carbapenem exposure , prior vancomycin/norvancomycin exposure were associated with VRE bloodstream infections .Logistic regression analysis confirmed that venous catheter was an independent risk factor of VRE bloodstream infections .Conclusions Venous catheter is an independent risk factor for VRE bloodstream infections . Infection control measures should be strengthened to prevent the outbreak of VRE‐related bloodstream infections .

Aim To investigate the antiarrhythmic mechanism of taurine-magnesium coordination com-pound on abnormal sodium current channel ( INa ) in-duced by hypoxia-reoxygenation in ventricular myocytes of rats. Methods Single ventricular myocytes were i-solated from each rat heart using enzymatic dissociation through Langendorff retrograde aortic perfusion. Whole-cell patch clamp was applied in voltage clamp mode to record INa both in normal ventricular myocytes and single ventricular myocytes of arrhythmia induced by hypoxia-reoxygenation. Results The peak density of INa was changed from ( 56. 89 ± 2. 07 ) pA/pF to (35. 05 ± 1. 52) pA/pF( n=6, P <0. 01 vs control) by hypoxia-reoxygenation with the INa I-V curve shifting upward. TMCC(200, 400 μmol·L-1)was able to re-store the reduction caused by H/R to (35. 78 ± 1. 95) pA/pF, (41. 52 ± 0. 86) pA/pF, (n=6,P <0. 01) and (48. 34 ± 0. 99) pA/pF(n=6,P<0. 01) respec-tively, but not at 100 μmol·L-1(n=6, P>0. 05), in a concentration-dependent manner, while amioda-rone restored it to (39. 44 ± 1. 24) pA/pF (n=6,P<0. 01 ) . Both high concentration of TMCC and amioda-rone could shift the I-V curve downward. In addition, TMCC and amiodarone could restore the INa inactivation curve and slow down its inactivation, whereas the acti-vation curves showed no significant differences among groups. Conclusion TMCC(200,400 μmol·L-1) could restore the H/R induced INa reduction and shift the I-V curve downward by inhibiting steady-state inac-tivation, which is suggested to be one of the mecha-nisms of the antiarrhythmic effects of TMCC in hypoxia-reoxygenation model.

An oxygen-tolerant denitrifying strain designated as H1 was screened by the procedures of shallow shaking and continuous aeration cultures.With the aid of an nnrS-gfp fusion responsive to nitric oxide (NO)and acetylene inhibition-GC procedure,it was shown that strain H1 was able to produce NO and N_2O but not N_2 under denitrifying conditions.Denitrifying processes were thus determined as NO_3~-→NO_2~-→NO→N_2O,with N_2O as the end product.Strain H1 could denitrify under shallow shaking conditions as well as in the initial atmospheric oxygen concentration ranging from 0～21%.Denitrification processed normally under continuous aeration at the rate of 2 L air per min in a 150 mL medium,but stopped under high aeration rate as 5 L air per min.16S rRNA gene sequence revealed that strain H1 shared 98% similarity to its closet relative Ralstonia taiwanensis,the genus where denitrifying bacteria are frequently found.

OBJECTIVETo investigate prevalence of human immunodeficiency virus (HIV) infection and risk factors for its transmission among injection drug users (IDUs) in Liangshan Yizu Autonomous Prefecture of Sichuan Province, China.

METHODSA community-based survey was conducted to investigate demographic characteristics, pattern and frequency of sharing injection equipment, and sexual behaviors in IDUs. Blood samples were also collected from them to detect for antibodies against HIV and syphilis.

RESULTSA total of 379 subjects were recruited with informed consent for study through community outreach and peer recruiting methods. Their prevalence of HIV infection was 11.3% (43/379). Ethnicity, frequency of sharing syringes and cotton swab during the past three months and syphilis infection associated with HIV infection by univariate analysis using chi-square test. Multivariate logistic regression analysis showed odds ratio of frequency of sharing syringes for HIV infection during the past three months was 2.28 (95% CI 1.18 - 4.43), and that for syphilis infection 3.10 (95% CI 1.48 - 6.48).

CONCLUSIONFrequency of sharing syringes during the past three months associated with syphilis and HIV infection.

This study was purposed to investigate the angiogenesis-promoting activities of human mesenchymal stem cells (hMSCs) modified by hepatocyte growth factor (HGF) and the underlying mechanisms. The hMSCs were transfected by recombinant adenoviral vector carrying human HGF gene and seeded onto the chicken chorioallantoic membrane. Three days later, the number of blood vessels was counted and their angiogenic response was compared with those of hMSCs of same generation, recombinant basic fibroblast growth factor (bFGF) and alpha-MEM as control. The expression levels of bFGF, VEGF, angiopoietin-1 and angiopoietin-2 were evaluated by RT-PCR assay. The results showed that gene-modified hMSCs exhibited greatest activity to promote angiogenesis while the angiogenic response was nearly same between groups treated by hMSCs and bFGF, all of which were significantly higher than that observed in control (p < 0.01). RT-PCR analysis revealed that hMSCs constitutively expressed multiple angiogenesis-associated growth factors and their levels seemed up-regulated by HGF gene transfer. It is concluded that HGF gene-modified hMSCs show a potent angiogenesis-promoting function and may be useful in the treatment of ischemic disorders.
