Objective To observe the histological changes of the liver in chronic HBV carriers aged above 40 years.Methods A total of 442 chronic HBV carriers aged above 40 years who underwent liver biopsy in Hepatology Hospital of Jilin Province from August 2012 to August 2015 were enrolled.Liver tissue samples were collected from all patients using ultrasound-guided rapid puncture,and the proportion of patients with grade ≥ G2S2 liver fibrosis or liver cirrhosis was calculated.The association of medical history of HBV infection,liver function,body mass index (BMI) and FibroScan with histological changes of the liver was analyzed.The t-test was used for comparison of continuous data between groups,relative risk (RR) was used to analyze risk factors,and a Kappa analysis was used for consistency test.Resuits Of all 442 chronic HBV carriers aged ≥40 years,56.56% had grade ≥ G2S2 liver fibrosis and 20.14% had liver cirrhosis.The length of the medical history of HBV infection and BMI were correlated with the degree of liver fibrosis,and medical history > 10 years(OR=64.06,95 % C I:33.72-121.69,P < 0.001) and B MI ≥ 24 (OR =6.93,95 % CI:4.64-10.35,P < 0.001) were risk factors for liver fibrosis and cirrhosis.There were significant differences between grade < G2S2 liver fibrosis patients and grade ≥ G2S2 liver fibrosis patients in the levels of alanine aminotransferase,aspartate aminotransferase,adenosine deaminase,gamma-glutamyl transpeptidase,alkaline phosphatase,and prealbumin (t =40.00,2.16,25.35,47.73,12.62,and 13.38,all P < 0.05).The consistency analysis of FibroScan and liver biopsy in the diagnosis of liver cirrhosis showed a Kappa value of 0.76,suggesting that there was a good diagnostic consistency between these two methods.Conclusion Monitoring and management of chronic HBV carriers aged above 40 years should be taken seriously in clinical practice,and liver biopsy should be performed as soon as possible for those with ALT > 30 U/L and marked liver fibrosis suggested by FibroScan.
Objective To explore the predictive factors of early diagnosis of liver cirrhosis in chronic HBV carriers (≥ 40 years old).Methods Total of 442 chronic HBV carriers (≥ 40 years old) underwent liver biopsy in Hepatology Hospital of Jilin Province form August 2012 to August 2015,the fibrosis stage of 89 cases were G4S4 (liver cirrhosis group) and 194 cases were below G2S2 (control group),these 283 cases were selected as investigate objects.Liver function,peripheral blood cell counts,HBV DNA levels,HBsAg quantitative and Fibroscan in both groups were analyzed and compared.Results The age,history of HBV infection,BMI and proportion of drinkers in liver cirrhosis group were higher than those in control group,the difference were statistically significant (P < 0.05).The ALT,AST,ADA,ALP,GGT and PALB of patients in liver cirrhosis group were (32.9 ± 7.4) U/L,(31.2 ± 10.3) U/L,(31.4 ± 10.1) U/L,(72.7 ± 31.6) U/L,(198.7 ± 32.8) U/L and (112.9 ± 31.4) g/L,respectively;the corresponding indicators of patients in control group were (15.3 ± 3.6) U/L,(29.8 ± 9.7) U/L,(10.7 ± 1.2) U/L,(22.6 ± 9.7) U/L,(102.8 ± 12.7) U/L and (311.7 ± 89.8) g/L,respectively,the differences were statistically significant (P < 0.05).PLT < 110 × 109/L and NEUT < 2.0 × 109/L were independent risk factors for liver cirrhosis (OR =29.33,14.42,P < 0.05).Fibroscan showed good coherence with liver biopsy,and Kappa value was 0.75.HBV DNA levels and HBsAg had no correlation with liver cirrhosis.Conclusion For chronic HBV carriers over 40 years,the age,history of hepatitis B,obesity,alcohol intake,PLT < 110 × 109/L and NEUT < 2.0 × 109/L were risk factors for liver cirrhosis.Fibroscan showed good coherence with liver cirrhosis.
在全球22个结核病高发地区中,我国是结核病高发地区,居全球第二。国家卫生部2000年第4次结核流行病学调查中显示,我国全年龄组结核分枝杆菌( MTB )感染率已达到44.5%,全国约5.5亿人感染了该菌,感染率高于全球人口感染率约1/3水平〔1〕。结核病是MTB通过微核传播的一种呼吸道疾病,与结核患者密切接触而感染MTB导致潜伏结核感染( LTBI)的人数是非常惊人的,潜伏感染者数目也十分庞大。大部分潜伏感染的转归终将会是活动性结核。本文就LTBI的新型诊断方法作一综述。
BACKGROUND:Chronic hepatitis B virus infection can impact the biological characteristics of bone marrow mesenchymal stem cel s. Adipose-derived mesenchymal stem cel s have gained more and more attention due to their high safety, little invasiveness, easy purification and rapid proliferation. OBJECTIVE:To establish the isolation and culture method of adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection in vitro, and to observe the biological characteristics of cel s. METHODS:Adipose-derived mesenchymal stem cel s were isolated from the subcutaneous fat of hepatitis B virus infection patients by col agenase digestion and adherent method. Growth curve of adipose-derived mesenchymal stem cel s were detected by MTT method and cel phenotypes were detected by flow cytometry. The adipogenic and osteogenic differentiation potential of adipose-derived mesenchymal stem cel s were detected in vitro. RESULTS AND CONCLUSION:(1) Adipose-derived mesenchymal stem cel s from 10 patients with hepatitis B virus infection were al isolated and cultured successful y. The primary passage time of adipose-derived mesenchymal stem cel s was (8.3±1.2) days. The growth curve of cel s was“S”shaped. Cel s came into a logarithmic phase at days 3-4, and came into platform at day 7. (3) Passage 3 adipose-derived mesenchymal stem cel s highly expressed CD29, CD166, HLA-ABC and CD44, but did not express or lowly expressed CD34 and HLA-DR. (3) Adipose-derived mesenchymal stem cel s differentiated into adipocytes after adipogenic induction, and differentiated cel s were positive for oil red O staining;after osteogenic induction, adipose-derived mesenchymal stem cel s differentiated into osteoblasts that were positive for alkaline phosphatase staining. These findings indicate that the col agenase digestion and adherent method can be used to effectively isolate adipose-derived mesenchymal stem cel s from patients with hepatitis B virus infection, and the cel proliferation is rapid so that a large number of cel s can be obtained in the short term.
Objective To determine whether the dynamic changes of the model for end-stage liver disease (MELD) scores were superior to baseline MELD scores in predicting the prognosis of HBV-related acute-on-chronic liver failure (HBV-ACLF). Methods A prospective study was made on HBV-ACLF patients hospitalized in four hospitals in China from 2009 to 2011. The clinical data including clinical manifestations, laboratory findings and the prognosis were observed, and the relationship between the dynamic changes of MELD scores and the prognosis was analyzed. Results The 90-day mortality rate of the enrolled 82 HBV-ACLF patients was 37.80%. The average baseline MELD scores in the non-survivor group and the survivor group were 25.50±4.77 and 23.72± 4.68, respectively, and the difference between the two groups was not significant (P=0.101). The MELD scores gradually increased in the non-survivor group, and decreased in the survivor group from the 7th day of enrollment. The differences were significant between the two groups at the following time-points. MELD scores of the survivors were significantly less than those of the non-survivors in the low-risk group (with the baseline MELD scores less than or equal to 23) from the 14th day of enrollment (16.04±4.00 vs 29.39± 12.30, P<0.05), and MELD scores of the survivors were significantly less than those of the non-survivors in the high-risk group (with the baseline MELD scores more than 23) from the 7th day of enrollment (22.38±4.91 vs 28.92±6.76, P=0.001). The variations became greater as time went on. Conclusion Dynamic changes of MELD scores should be considered additionally in predicting the prognosis of HBV-ACLF besides baseline MELD scores, which will help improve the accuracy of predicting the prognosis.

目的:观察肝衰竭各阶段的肝脏储备情况,探讨肝脏储备功能检测在肝衰竭人工肝治疗中的应用价值。方法:将我院收治的肝衰竭患者178例纳入研究,并根据其临床表现的严重程度,按照早、中、晚三期,将入组患者分为3期。并对其中89例患者行人工肝治疗,另外89例予常规治疗,作为对照组。结果:肝衰竭早、中、晚期的肝脏储备功能逐渐下降,各组间比较差异有统计学意义。人工肝手术组肝衰竭早中期的死亡率明显低于常规治疗组,肝衰竭晚期的死亡率与常规治疗组无明显差异。人工肝治疗前后肝脏储备功能无明显变化。经人工肝治疗后,肝脏储备功能较好的肝衰竭早期患者死亡率较肝脏储备功能较差的肝衰竭晚期患者死亡率低。结论:人工肝治疗不能在短时间内改善肝脏储备功能,肝脏储备功能检测可协助指导肝衰竭患者的人工肝治疗。
>失代偿期肝硬化属于终末期肝病(end stage liver disease,ESLD)最常见的类型,是肝硬化的晚期阶段,其主要特征为肝细胞数量与功能不能满足人体的生理需求。肝脏是机体营养物质代谢的中心器官,肝损害会引起机体不同程度的物质与能量代谢障碍。营养不良的严重程度与该类患者的预后及并发症的发生又关系密切。因此,营养支持治疗在失代偿期肝硬化治疗中占重要的地位。但因为种种原因,我国在这一领域研究较少。本研究针对失代偿期肝硬化患者进行了初步肠内营养干预,现将结果报告如下。一、资料与方法1.研究对象:选择2011年9月至2012年1月在我院住
