[Objective]To evaluate the two-dimensional shear wave elastography(2D SWE)in predicting the prognosis of the patients with acute-on-chronic hepatitis B liver failure(ACLF-HBV).[Methods]312 patients diagnosed with ACLF-HBV at the De-partment of Infectious Diseases in the Third Affiliated Hospital of Sun Yat-sen University from October 1st 2013 to December 31th 2015 were recruited. The baseline data of all patients,including 2D SWE,laboratory data,ultrasonographic data,Model for End-stage Liver Disease score(MELD),Child-Turcotte-Pugh score(CTP),and King′s College Hospital score(KCH),were collected when enrolled. All patients were followed up for at least 90 days and their clinical outcomes(recovering or worsening)were recorded. 2D SWE values of all patients were dynamically collected every 2~4 weeks during the follow-up until death,liver transplantation, or discharging from hospital.[Results]The worsening patients showed higher 2D SWE values than the recovering ones[(44.0 ± 7.5) kPa vs(36.8 ± 10.3)kPa,t=-6.5,P=0.000],2D SWE value less than 39.2 kPa could be a prediction of the patient′s recovery in 90 days.The predictive value of 2D SWE(AUROC=0.73)was higher than that of KCH(AUROC:0.65,z=2.1,P=0.033). Among all the dynamically measured patients,2D SWE rose from(42.1 ± 8.0)kPa to(47.5 ± 9.3)kPa in the worsening group during the 90-day follow-up,while nearly stable in the recovery group.[Conclusion]Noninvasive liver stiffness measurement by 2D SWE is a use-ful method in evaluating the prognosis of ACLF-HBV patients. Taking a cutoff of 39.2 kPa,patients with higher 2D SWE values could have worse clinical outcomes ,otherwise better. It seems that dynamically measuring 2D SWE values could also be helpful ,but more research in the future should be needed.

At present, a large quantity of patients with end-stage liver diseases are still waiting for liver transplantation. Evaluation of donor liver quality with rapid, convenient, non-invasive and accurate methods plays a pivotal role in improving the prognosis and quality of life of liver transplant recipients. No standard evaluation criteria of donor liver quality have been established in clinical practice. Comprehensive evaluation methods have been primarily adopted, including clinical parameters of donors, laboratory examination, imaging examination and pathological examination, etc. Conventional ultrasound and contrast-enhanced ultrasound may evaluate the quality of donor liver before liver transplantation and predict the incidence of complications after liver transplantation, which are of significant application prospect in liver transplantation. In this article, the basic methods and research progress on conventional ultrasound and contrast-enhanced ultrasound in evaluating the vascular variation of donor liver, micro-circulatory perfusion of liver parenchyma, degree of steatosis of donor liver, degree of fibrosis of donor liver, volume and quality of donor liver were reviewed, aiming to provide more methods and ideas for clinical evaluation of donor liver quality.

OBJECTIVETo evaluate the effect of combined chemoradiotherapy followed by surgery for patients with esophageal carcinoma.

METHODSNinety-seven patients with stage II or III esophageal carcinoma without contraindication against operation and chemoradiotherapy, were randomly divided into two groups: combined group (Group A) 48 and control group (Group B) 49. Patients in group A were given neoadjuvant treatment consisted of chemotherapy with 5-fluorouracil and cisplatin for 2 cycles and radiotherapy of DT36 Gy/12 f/17 d. Three weeks later, operation was performed. Patients in group B were given operation alone. Survival rate was calculated with Kaplan-Meier method. Chi and Log-rank test was used to assess the difference between the two groups.

RESULTSThe radical resectability of group A and group B were 85.4% and 65.3% (P = 0.018 1). The lymph node metastasis rate of the two groups were 21.7% and 45.7% (P = 0.019 4). The T stage of group A was significantly lowered (P = 0.003 6). The local and regional recurrence rate of two groups were 34.8% and 58.7% (P = 0.023 6), while there was no significant difference in operative complications between the two groups. Significant improvement in the long-term survival rate was observed in group A, especially in patients who achieved partial and complete response with high 5-year survival rate of 56.5%.

CONCLUSIONPreoperative neoadjuvant chemoradiotherapy is able to reduce the tumor and tumor stage, lower the lymph node metastasis rate and local or regional recurrence rate, also it can improve radical resectability and long-term survival without increasing the operative complications.

To evaluate the impact of intrahepatic cholestasis on liver stiffness measurement ( LSM ) of two‐dimensional shear wave elastography ( 2D‐SWE ) in patients with chronic hepatitis B . Methods Between June 2011 and December 2016 , total of 1 188 patients with chronic hepatitis B infection were enrolled to collect clinical ,2D‐SWE ,biochemical variables and histological ( M ET AVIR scoring system ) datas . LSM was compared between normal total bilirubin group ( TB ＜ 23 .9 μmol/L ) versus abnormal TB group( ≥23 .9 μmol/L ) . Correlation of TB with LSM s was assessed . Results Nine hundred and seventy‐three patients with effective LSM in the study were analyzed . Within the same fibrosis stage ( F1‐F4) ,LSM showed significantly higher value in abnormal TB group than those of normal TB group ( r＝0 .328 ,0 .247 ,0 .495 ,0 .435 ,all P ＜ 0 .001 ) . Increased LSM for abnormal TB group was generally found within different subset of patients [ fibrosis stage ≤ F2 ,AL T ≥ 2 × upper limit of normal ( ULN ) ;fibrosis stage≤ F2 ,M ET AVIR activity grade ≤ A1 or ≥ A2 ] ,with r ＝ 0 .266 ,0 .210 ,0 .243 ( all P ＜0 .001) ,respectively .Increased LSM for abnormal TB group was also found within different subset of patients [ fibrosis stage≥F3 ,AL T＜2× ULN ,≥2×ULN ; fibrosis stage≥F3 ,M ET AVIR activity grade≥A2 ,with r ＝ 0 .671 ,0 .200 ,0 .468 ( all P ＜ 0 .05 ) ] . Conclusions Hepatogenous jaundice induced to intrahepatic cholestasis shows slight positive correlation with LSM s in patients with chronic hepatitis B .
