Objective To evaluate the value of ultrasonic quantitative method in the diagnosis of liver fibrosis in chronic hepatitis B (CHB) patients. Methods Ultrasonography was performed in 186 CHB patients who underwent liver biopsies. Fifteen indices including liver capsule thickness and fourteen texture parameters of gray level co-occurrence matrix were extracted from standard sonograms and compared with fibrosis stages by histopathology. The status of liver fibrosis was divided into five stages from S0 to S4 by histopathology based on the disease severity. ANOVA and Spearman correlation analysis were applied to analyze the differences and relationships between these indices and pathological stage, respectively. Then discriminant analysis models were established based on the indices for quantitative diagnosis of liver fibrosis. Results Among the fifteen indices, including liver capsule thickness, only the variance (F=0. 55, r=0. 06; both P＞0. 05), sum average (F=0.61, both r=0.05 ; P＞0.05), sum entropy (F=1.68, r=0.09; both P≥0.05) and entropy (F=1.39,r=0.12; both P＞0.05) were not significantly associated with the stages and not manifested linear correlation. Using biopsy results as gold standard, the correct rank rate of discriminant analysis model analysis in the patients staged from S0 to S4 were 80. 0%, 64. 9%, 61.3%, 74. 1% and 80.6 %, respectively. There were 73.1% of cross-validated cases who were accurately classified by the model analysis. The sensitivity, specificity and accuracy in patients with stage ≥ 1 were 97. 6%,80.0% and 91.9%, respectively; those in patients with stage≥2 were 92.1%, 89.7% and 90.9%,respectively; those in patients with stage≥3 were 94.8%, 96.1% and 95.7%; and those in patients with stage 4 were 80. 6%, 97.4 % and 94.6%, respectively. When considered S0 as no fibrosis, S1 as mild fibrosis, S2 and S3 as moderate to severe fibrosis and S4 as early cirrhosis, the consistence rates between discriminant analysis model and biopsy result were 81.7%, 78. 4%, 56. 9% and 90.3%,respectively. There were 74.7% of cross-validated cases who were correctly classified. The sensitivity, specificity and accuracy of the models for determining the fibrosis severity in patients≥mild fibrosis were 97.6%, 81.7% and 92.5%, respectively; those in patients ≥ moderate to severe fibrosis were 83. 1%, 94.8% and 89.2%, respectively; those in patients with early cirrhosis were 90.3%, 93.5% and 93.0%, respectively. Conclusion As a novel and noninvasive method, ultrasonic texture analysis could quantitatively determine liver fibrosis in CHB patients and is worthy of further investigation.

Objective To observe the clinical efficacy of coupled plasma filtration adsorption (CPFA) combined with high volume hemofiltration (HVHF) for severe acute pancreatitis (SAP) and explore the practicality, the safety and the therapeutic mechanism. Methods This was a prospective, randomized clinical trail. A total of 29 patients with SAP were di-vided into two groups:treatment group (n=15, CPFA and HVHF) and control group (n=14, HVHF). The APACHEⅡscore, se-rum triglyceride, liver and kidney function, white blood cell (WBC), heart rate (HR), respiration, mean arterial pressure (MAP) and oxygenation index were compared before and after treatment between two groups. The organ function was as-sessed, and the adverse reactions and prognosis were observed in two groups. Results After treatment, there were signifi-cant decreases in APACHEⅡscore and WBC, and significant increase in PaO2/FiO2 in two groups, especially significant in treatment group. There was a significant decrease in the level of triglycerides in 7-d treatment group than that of 3-d treat-ment group (P＜0.05). There were no thrombocytopenia, bleeding, allergies, blood clotting and other adverse reactions in two groups of patients. There were significant decreases in the blood purification time and the length of hospital stay in treatment group than those of control group (P＜0.05). There was no significant difference in mortality between two groups. Conclu-sion CPFA combined with HVHF can effectively control inflammation, reduce the serum level of triglyceride and improve the prognosis in patients with SAP.

Objective To compare clinical biochemical and pathological characters among antimitochondrial antibody-negative primary biliary cirrhosis (AMA PBC),AMA positive PBC (AMA+ PBC)and autoimmune hepatitis (AIH),and try to find serum biomarkers in the diagnosis of AMA-PBC.Methods From January 2005 to May 2013,23 patients with AMA-PBC,102 patients with AMA+ PBC and 55 patients with AIH were collected.Clinical features of patients were observed.Biochemical indexes (total bilirubin (TBil),direct bilirubin (DBil),alanine aminotransferase (ALT),aspartate transaminase (AST),alkaline phosphatase (ALP),γ-glutamyltransferase (GGT) and globulin) were tested.Immunological indexes immunoglobulin ((Ig)G,IgM and IgA) were also measured.Antinuclear amibody,anti smooth muscle antibody (SMA) and AMA were detected by indirect immunofluorescence.Soluble acidic phosphorylation nucleoprotein antibody and anti-nuclear membrane glycoprotein antibody were detected by Western blotting.Non parameter test was for non normal distributed measurement data and grade data comparison.The cut off value,sensitivity and specificity of IgM in the diagnosis of PBC were calculated with receiver operating characteristic (ROC) curve.The sensitivity and specificity of soluble acidic phosphorylation nucleoprotein antibody and anti-nuclear membrane glycoprotein antibody in the diagnosis of PBC were analyzed with fourfold table.Results The rates of fatigue and jaundice of AMA-PBC group (39.1％,9/23 ; 43.5 ％,10/23) were both higher than those of AIH group (16.4 ％,9/55; 14.5 ％,8/55),and the differences were statistically significant (x2 =4.735 and 7.648,both P＜ 0.05).The levels of ALP and GGT of AMA PBC group were higher than those of AIH group,and the levels of ALT and AST were lower than those of AIH group (Z=-4.577,-4.257,-2.820 and -2.055,all P＜0.05).The level of IgM of AMA PBC group (417(270,610) mg/L) was higher than that of AIH group (97(69,195) mg/L),however lower than that of AMA+ PBC group (546(419,704) mg/L),and the differences were statistically significant (Z=-4.362 and-0.210,both P＜0.05).The level of IgG of AMA PBC group was lower than that of AIH group (Z=-2.202,P＜0.05).The positive rates of antinuclear antibody and SMA of AMA PBC group (95.7％ (22/23),8.7％ (2/23)) were both higher than those of AMA+ PBC group (33.3％(34/102),1.0％(1/102)),and the differences were statistically significant (x2 =29.474 and 4.769,both P＜0.05).The positive rates of soluble acidic phosphorylation nucleoprotein antibody and anti nuclear membrane glycoprotein antibody of AMA PBC group (60.9％,14/23; 30.4％,7/23) were both higher than those of AIH group (2.0％,1/55; 0),and the differences were statistically significant (x2=36.409 and 24.329,both P＜0.05).The karyotype of antinuclear antibody of AMA PBC and AMA+ PBC group mainly was granules pattern (60.9 ％,14/23;75.5％,77/102),however of AIH group was mainly homogeneous pattern (38.2％,21/55).If the cut off value of IgM was 277 mg/L,the sensitivity and specificity of IgM in the diagnosis of PBC was 72.2％ and 94.4 ％.The sensitivity and specificity of soluble acidic phosphorylation nucleoprotein antibody in the diagnosis of PBC was 24.1％ and 97.2％.The sensitivity and specificity of anti-nuclear membrane glycoprotein antibody was 35.2 ％ and 100.0 ％.The sensitivity and specificity of any one of anti-nuclear membrane glycoprotein antibody positive,soluble acidic phosphorylation nucleoprotein antibody positive or IgM＞277 mg/L in the diagnosis of PBC was 88.9％ and 94.4％.Conclusions AMA-PBC and AMA+ PBC have similar clinical manifestations and serum biochemical test results.Antinuclear antibody and/or SMA positive is the feature of AMA-PBC and which should be distinguished with AIH.The sensitivity and specificity of any one of the followiags:anti nuclear membrane glycoprotein antibody positive,soluble acidic phosphorylation nucleoprotein antibody positive or IgM＞277 mg/L is high in the diagnosis of PBC.

Objective To study the age peak of incidence,pathologic sites,therapeutic effect and complications of different treatment for hip fractures in the elderly.Methods Hip fractures,therapy,elderly were used as key words to search articles both in English and Chinese from 1979 to 2017.The articles were filtrated by title,abstract and full text and 32 of them were left.All the patients were objects of this study,but the repeated cases were excluded.The patients' data such as age of onset,gender,fracture type,operation method,follow-up time,and complications were collected and analyzed by systematic analysis.Results Data of 2 758 patients in 32 papers had been collected for analysis.There were 1791 femoral neck fractures and 967 intertrochanteric fractures,with a ratio of 1.85:1.The patients' age of onset was ranging from 54 to 92 years old,with an average of 76.7 years old,and the age peak of incidence was from 70 to 79 years old.The sex ratio was 1:1.66 (1 037 males:1721 females).All the patients had been followed up for 0.5 to 18 years,(average,7.8 years).Among 927 femoral neck fractures who were treated by 3 lag screws,there were 278 cases of non-union (29.9％),139 femoral head necrosis(15.1％) and 19 internal fixation loosening (2.0％);but for 183 femoral neck fractures who were treated by dynamic hip screws (DHS),there were 51 cases of non-union (28.1％),31 femoral head necrosis(17.0％),3 internal fixation losening(1.8％),and 27 cutting effect (15％).Then for 400 femoral neck fractures who were treated by hemiarthroplasty,there were 6 cases of dislocation(1.5％),14 shaft fracture (3.5％),8 deep infection (2.0％);while for 281 femoral neck fractures who were treated by total hip arthroplasty,there were 14 cases of dislocation (5.0％),11 shaft fracture (4.0％),and 10 deep infection (3.5％).On the other hand,for 354 intertrochanteric fractures who were treated by proximal femoral nail or proximal femoral nail antirotation internal fixation (PFN or PFNA),there were 18 cases of trochanter fracture (5.0％),28 hip varus (8.1％),32 displacement (9.0％);and for 210 intertrochanteric fractures who were treated by Gamma nail,there were 17 cases of trochanter fracture (7.9％),11 cutting effect (5.0％),6 displacement (3.0％);and for 135 intertrochanteric fractures who were treated by DHS,there were 8 cases of cutting effect (6.1％),7 displacement (5.2％);and for 101 intertrochanteric who were treated by proximal femoral locking plate,there were 5 cases of displacement (5.0％);Also for 89 intertrochanteric fractures who were treated by hemiarthroplasty,there were 2 cases of dislocation(1.8％),3 shaft fracture (3.0％),1 deep infection(1.5％);and for 78 intertrochanteric fractures who were treated by total hip arthroplasty,there were 4 cases of dislocation (4.8％),3 shaft fracture (4.0％),2 deep infection (2.5％).Conclusion The elderly hip fractures' age peak of incidence is from 70 to 79 years old,and femoral neck fracture takes up a majority of it.Female patients are more than male patients.The femoral neck fractures are mainly treated by 3 lag screws internal fixation;non-union and femoral head necrosis are the common complications postoperation.While the intertrochanteric fractures are mainly treated by proximal femoral nails;displacement,hip varus and trochanter fractures are the common complications postoperation.The artificial hip replacement is the effective remedy measure for secondary femoral head necrosis after hip fractures.
