Rrelationship between liver volume atrophy rate,liver stiffness measurements and Child-Turcotte-Pugh value with Laennec histopathological classification in patients with hepatitis B cirrhosis / 重庆医学

Objective To explore the relationship between the liver volume atrophy rate,liver stiffness measurements(LSM) and Child-Turcotte-Pugh(CTP) value with the Laennec histopathological classification in the patients with hepatitis B cirrhosis and its value in the quantitative diagnosis of liver cirrhosis degree.Methods The clinicopathological data of liver biopsy tissue pathological slides,FibroScan,CT examination and hematological detection in 32 cases of hepatitis B cirrhosis were retrospectively analyzed.Liver cirrhosis was divided into mild,moderate and severe according to the Laennec liver cirrhosis histopathological classification.Then the relationship between the liver volume atrophy rate,LSM and CTP score with liver cirrhosis histopathological.Results Among 32 cases,9 cases(28.12％) were mild,12 cases(37.50％) were moderate and 11 cases(34.38％) were severe.The liver volume atrophy rates of mild,moderate and severe groups were (16.75±2.20)％,(23.11±6.67)％ and(35.55±5.70)％ respectively;LSM were(14.96±3.36),(20.21± 3.07),(37.03 ± 16.44) kPa respectively,the difference among 3 groups was statistically significant (P＜ 0.01).The CTP scores had no statistical difference among the 3 groups were(P＞0.05).The cirrhosis histopathological grade had the positive correlation with the liver volume atrophy rate and LSM(r=0.93,0.74,P＜0.01),however had no obvious correlation with the CTP scores(r=0.27,P＞0.05);the liver volume atrophy rate was positively correlated with LSM and CTP score(r=0.90,0.91,P＜0.01);while LSM had no obvious correlation with CTP score (r =0.15,P ＞ 0.05).Conclusion The more severe the cirrhosis histoathological grade,the bigger the liver volume atrophy rate and the higher the FibroScan detection value;the liver volume atrophy rate and LSM may serve as the quantitative diagnosis indicators of liver fibrosis histopathological severity.

Expression and significance of CXCL5 and CXCL8 in hepatic fibrosis and cirrhosis tissues / 中华消化外科杂志

Objective To investigate the level of chemotactic factors(CXCL5 and CXCL8)in hepatic fibrosis and cirrhosis tissue.Methods Hepatic tissues were obtained from 9 patients with hepatic hemangioma (hepatic hemangioma group),10 patients with liver fibrosis(liver fibrosis group)and 11 patients with liver cirrhosis(1iver cirrhosis group)at Nanfang Hospital from May 2008 to May 2009.The contents of CXCL5 and CXCL8 in hepatic tissue were assayed by ELISA.All data were analyzed by one-way ANOVA,Pearson rank correlation or Spearman correlation.Results The contents of CXCL5 and CXCL8 were(0.8±0.7)ng/g and(6.2±3.7)ng/g in hepatic hemangioma group,(2.0±2.0)ng/g and(11.6±3.5)ng/g in liver fibrosis group and (17.1±4.8)ng/g and(12.3±3.9)ng/g in liver cirrhosis group,with significant difference among the 3 groups (F=60.050,7.690,P＜0.05).The expression of CXCL5 was correlated with the content of alanine aminotransferase(ALT),aspartate aminotransferase(AST)and prothrombin time(PT)(r=0.502,0.468,0.523,P＜0.05):the expression of CXCL8 was correlated with the content of ALT,AST.total bilirubin and PT(r=0.477,0.504,0.537,0.431,P＜0.05).Conclusions With the aggravation of hepatic fibrosis,the contents of CXCL5 and CXCL8 are increased with different patterns.The changes of CXCL5 and CXCL8 are related with the injury of liver,but the changes of CXCL5 and CXCL8 do not correspond with the degree of the injury of liver.

An experimental study on the expression of apoptosis conducted by nuclear factor-?B in benign and malignant pancreatic diseases / 医学研究生学报

Objective:By measuring the expression of nuclear factor of ?B(NF-?B) and apoptosis in the tissue of benign and malignant pancreatic diseases.Methods:The expression of NF-?B factor was measured by immunohistochemical method to measure.The expression of apoptosis for cells was determined by TUNEL method.Results: When measuring the expression of NF-?B p65 protein in the tissue,we found firstly,in the tissue of pancreatic cancer,NF-?B p65 protein was located in the nucleolus and cytoplasm,the number of positive cell was obviously more than that in the control group(P

Clinicopathological features of resectable carcinoma of the pancreatic head:a report of 102 cases / 中国普通外科杂志

Objective To explore the clinicopathelogical features of resectable carcinoma of the head of (pancreas).Methods A retrospcctive analysis was made on the clinicopathological data of 102 patients with cancer of the head of pancreas, who had received pancreatoduodenectomy from Nanfang Hospital in January 1990 to January 2003. Results The incidence rate of the peri-pancreatic tissue infiltration was 74.5%,the infiltration rate of retroperitonealfat was 27.5% and the incidence rate of peri-pancreatic lymph-node (metastasis) was 71.6%. Metastasis rate of 21.1% was seen in the abdominal aorta lymph nodes. (Conclusions) Surgically resectable carcinoma of the pancreatic head is not equivalent to early cancer. The surgical area of radical resection of cancer of the pancreatic head should at least include pancreatoduodenectomy and clearance of regional soft tissue and lymph nodes. It may be more reasonable if the abdominal aorta lymph nodes were assigned to the first station of lymph drainage of carcinoma of head of the pancreas.
