Objective To assessment short-term prognosis in patients with acute on chronic liver failure , several scoring systems were compared. Methods Two hundred and sixteen patients with acute on chronic liver failure were divided into survival group and death group according to the results of 90 days after admission.CTP , MELD,APACHEⅡ, SOFA and SMSVH score were calculated.After ROC curves were performed ,the areas under the curves of these scoring systems were compared. Results The areas under the ROC curves of MELD, APACHEⅡ, SOFA, CTP and SMSVH were 0.88, 0.76, 0.89,0.79and 0.69,respectively. The areas under the curves of SOFA and MELD were larger than the APACHEⅡ, CTP and SMSVH (P<0.05). There was no difference between the SOFA and MELD (P>0.05). The area under the curve of CTP was larger than the APACHEⅡ, but there was no statistically significant difference (P > 0.05). The area under the curve of SMSVH were less than 0.7. Conclusions The SOFA, MELD,CTP and APACHEⅡcan predict the short-term prognosis of acute on chronic liver failure. The SOFA and MELD are the best scoring systems.CTP,APACHEⅡ are better than SMSVH. SMSVH fail to predict the prognosis of acute on chronic liver failure.

Objective To investigate the associations of peripheral CD4+ CD25 + CD127low/-regulatory T cells (Treg) with HBV viral load and liver pathology in hepatitis B virus (HBV) carriers.Methods Forty six chronic HBV carriers admitted in the first hospital of Jiaxing during October 2012 and February 2014,and 23 healthy subjects (controls) were enrolled in the study.CD4+ CD25 + CD127low/-Treg in peripheral blood of the two groups were detected by flow cytometry.Ultrasound-guided liver biopsies were performed in chronic HBV carriers and HBV DNA load was determined by real-time PCR method.Independent samples t test was used for the comparison between groups,and Spearman rank correlation or Pearson linear correlation analyses were performed.Results The frequency of the peripheral CD4+ CD25+CD127low/-Treg in 46 HBV carriers was (5.11 ±1.47)%,which was significantly higher than that in healthy controls [(3.46 ± 1.23) %,t =4.629,P < 0.01].The HBV DNA load in HBV carriers was (6.21 ±1.98)lg copies/mL,which was positively correlated with the CD4+ CD25+ CD127low/-Treg level (r =0.405,P < 0.01).Among 46 HBV carriers,21 (45.65%) were of inflammation grade 2 or above,and 16 (34.78%) were of fibrosis stage 2 or above.Peripheral CD4+ CD25+ CD127low/-Treg level was negatively correlated with inflammation and fibrosis in HBV carriers (r =-0.343 and-0.452,P < 0.05).Conclusion CD4 + CD25 + CD127low/-Treg may be associated with the chronicity of HBV infection and the degree of liver damage.

OBJECTIVETo study the hemodynamics of the pulmonary artery (PA) in pulmonary artery hypertension (PAH).
METHODSWith combined clinical hemodynamic measurements and CT data, the 3D model of PA and its branches was reconstructed to obtain the real 3D geometric structure of PA and its branches. Computational fluid dynamics (CFD) simulation was carried out for the reconstructed 3D geometric model of the PA and its branches with Womersley velocity as main pulmonary entrance conditions; then hemodynamic parameters of the PA and its branches in cardiac cycle were calculated and the changes of flow field, pressure, wall shear stress (WSS) at different times, and its impact on physiological processes were analyzed.
RESULTSimulation showed that the pressure of the main PA and the branches of the left and right PA was higher in the systolic period than that in the diastolic period; especially, the that of right PA and its interlobular artery was significantly higher than that of the left. The blood flow velocity of the main PA and its branches of right and left PA was significant different, the velocity was much higher at the distal of the right PA than that at the left. High WSS field formed at the proximal of the right PA before the branches during the systolic.
CONCLUSIONThe right PA at the proximal and lower lobe artery are affected by much larger pressure and change firstly, so the change of morphological and functional of theses segments will be have more important value to prompt existence of the early PAH.

OBJECTIVETo evaluate the preliminary curative effect of interspinous injections for the diagnosis and treatment of back pain caused by lumbar kissing spine (Baastrup's disease) under fluoroscopically guiding.
METHODSFrom November 2011 to March 2013,17 patients with back pain caused by Baastrup's disease were treated with fluoroscopically-guided interspinous injections, including 7 males and 10 females with an average age of 49.6 years old ranging from 40 to 71 years old; the duration of the disease ranged from 2 to 5 years with a mean of 3.7 years. The visual analogue scale (VAS) and the lumbar segments range of motion (ROM) was analyzed at pre-operation, 2 days, 3 months and final followed-up after operation, the effects were evaluated with modified Macnab standard.
RESULTSAll patients were follow-up from 6 to 10 months with an average of 7.6 months. The pre-operative VAS was 6.41 +/- 0.94, the postoperative VAS at different time points improved significantly comparing with pre-operation,and the differences were statistically significant (P < 0.01). There was no significant difference in VAS at different time points after operation (P > 0.05). The ROM of operated segment and adjacent segment was (4.88 +/- 0.86) degrees and (6.82 +/- 0.73) degrees respectively at pre-operation. The postoperative operated segment ROM at different time points improved significantly comparing with pre-operation, and the differences were statistically significant (P < 0.05). Compared with pre-operation, there was no significant difference in adjacent segment ROM at different time points after operation (P > 0.05). According to modified Macnab, the result was excellent in 6 cases, good in 7 cases, fair in 3 cases and poor in 1 case.
CONCLUSIONFluoroscopically-guided interspinous injections is an effective method for the diagnosis and treatment of Baastrup's disease. The method has advantages of simple operation, minimal invasion and safety, satisfactory short-term and medium-term therapeutic effect; it can also effectively lessen the pain of lumbar and back.

Syndrome of resistance to thyroid hormone(RTH)is a rare hereditary thyroid disease with various clinical manifestations and laboratory findings. RTH could be misdiagnosed and mistreated, resulting in aggravation of the disease. We reviewed the medical records of a patient with RTH over the past six years. In addition, we provided a summary of latest progress for RTH to help the clinicians to improve the understanding of the disease.

To analyze killer immunoglobulin (Ig)-like receptor (KIR) gene content and allelic polymorphism in Zhejiang Han population, samples were genotyped by polymerase chain reaction sequence-specific primers (PCR-SSP). The results demonstrated that all 17 KIR genes could be observed in the population. All individuals contained 2DL4, 3DL2 and 3DL3 genes. The frequencies of these genes was 1.00. 2DL1, 2DL3, 2DP1, 3DP1*003, 3DL1, 2DS4*001/002 loci were more common, their frequencies were 0.902, 0.902, 0.902, 0.902, 0.7598, 0.5615 respectively, while the frequencies of 2DL2, 2DL5A, 2DL5B, 2DS1, 2DS2, 2DS3, 2DS4*003, 2DS5, 3DS1 and 3DP1*001/002 were relatively lower. The A KIR haplotype was the most prevalent (74.7%) in Zhejiang Han population and there were 12 different KIR haplotypes in total, the most common was 2 (53.0%). Twenty six different genotypes have been found in the population, AJ (2, 2) and AF (1, 2) showed higher frequencies, followed by AH (2, 5), NN2 (2, 6), AI (1, 5) and AG (1, 1). Fifteen of these genotypes have not been found in Caucasians so far and four new KIR profiles could not be assigned to the haplotypes according to standard assign method. In conclusion, there are distinctive frequencies of KIR gene content, haplotype as well as genotype in Zhejiang Han population.
