OBJECTIVETo investigate the histopathological features in livers of chronic severe hepatitis B (CSHB) patients.
METHODSHistology of 42 livers was studied. HE, Masson, Sweet and D-PAS staining and cytokeratin 7, CD68 and proliferating cell nuclear antigen immuno-histochemical staining were used in the study.
RESULTSIn CSHB, the livers showed massive or submassive necrosis in a background of other histological changes of chronic hepatitis B. The characteristic pictures of these livers were necrosis of all the hepatocytes in some nodules, while in other nodules there were only patchy necroses of the parenchyma. In some other nodules the necrotic hepatocytes were all removed and only the scaffolding stroma remained. Meanwhile, regeneration of hepatocytes and bile ductules were also seen.
CONCLUSIONSThe liver histopathological changes in CSHB are identical, but not of the same degree as those of acute severe and subacute severe hepatitis B. In making differential diagnoses for liver aspiration biopsies of these patients, this fact should be kept in mind.

OBJECTIVEIn China, liver failure is also termed as severe hepatitis in whom chronic severe hepatitis B (CSHB) is most common. The aim of this study was to assess whether CSHB based on different liver injury extent can meet the international definition of acute-on-chronic liver failure(ACLF)criteria, according by their clinical and pathological feature.
METHODSA total of 91 patients with CSHB were involved in the study. The clinical findings, laboratory data and liver pathology features were retrospectively analyzed and grouped by hepatitis virus B carrier state (HBC), chronic hepatitis B (CHB) or liver cirrhosis (LC) before they started liver failure.
RESULTS74 out of the 91 patients were male and 17 were female, the mean age was 40.6+/-11.2 years. 9.9%, 7.7% and 82.4% of the patients were based on HBC, CHB and LC respectively. The ages of HBC group were youngest. The mean age of HBC group (years) (25.8+/-6.6) was significantly lower than that of CHB group (36.9+/-9.0) and LC group (42.0+/-10.5)with P values of 0.032 and 0.001 respectively. Most cases presented with sub-acute liver failure characterized by high icterus and ascites. Predisposing factors included exertion, superinfection, virus variation, drugs or alcoholic injury. No difference found between PTA (F = 0.906, P = 0.408) and TBil (F = 0.839, P = 0.436) among the above three groups. The Alb and CHE levels in LC group were (30.3+/-5.1) g/L and (2926.8+/-1471.1) U/L respectively, which were lower than both HBC group [Alb (35.6+/-5.1) g/L, CHE (4363.5+/-2063.2) U/L] and CHB group [Alb (37.4+/-5.0) g/L, CHE (5167.1+/-1522.1) U/L] (F = 9.450; F = 9.297; P value less than 0.01).The level of CHO (1.8+/-1.0) mmol/L in LC group was lower than that of HBC group (2.9+/-1.0mmol/L, P = 0.034), while serum HBV DNA level of HBC group [(6.8+/-1.7) log10copies/ml] was higher than that of LC group [(4.2+/-2.6) log10copies/ml]. The liver tissue in HBC and CHB group showed massive or submassive necrosis which distribute evenly in different parts of liver and similarly in slides, most like acute/subacute severe hepatitis. The chronic lesion was easily covered by extensive necrosis in CSHB based on CHB, with portal fibrosis can be seen by masson stain. Characteristic picture of LC group were massive or submassive necrosis with some nodules were intact or only patchy necrosis of the parenchyma, disparity of extent and stage of necrosis existed in slides, which were the major difference in histopathological change in HBC and CHB group.
CONCLUSIONMost of CSHB cases were based on liver cirrhosis, which match with the international definition of ACLF, while small part of CSHB cases based on HBC and CHB are identical to acute/subacute liver failure.

Newcastle disease virus (NDV) and Salmonella Pullorum have significant damaging effects on the poultry industry, but no previous vaccine can protect poultry effectively. In this study, a recombinant-attenuated S. Pullorum strain secreting the NDV hemagglutinin-neuraminidase (HN) protein, C79-13ΔcrpΔasd (pYA-HN), was constructed by using the suicide plasmid pREasd-mediated bacteria homologous recombination method to form a new bivalent vaccine candidate against Newcastle disease (ND) and S. Pullorum disease (PD). The effect of this vaccine candidate was compared with those of the NDV LaSota and C79-13ΔcrpΔasd (pYA) strains. The serum hemagglutination inhibition antibody titers, serum immunoglobulin G (IgG) antibodies, secretory IgA, and stimulation index in lymphocyte proliferation were increased significantly more (p < 0.01) in chickens inoculated with C79-13ΔcrpΔasd (pYA-HN) than with C79-13ΔcrpΔasd (pYA) but were not significantly increased compared with the chickens immunized with the LaSota live vaccine (p > 0.05). Moreover, the novel strain provides 60% and 80% protective efficacy against the NDV virulent strain F48E9 and the S. Pullorum virulent strain C79-13. In summary, in this study, a recombinant-attenuated S. Pullorum strain secreting NDV HN protein was constructed. The generation of the S. Pullorum C79-13ΔcrpΔasd (pYA-HN) strain provides a foundation for the development of an effective living-vector double vaccine against ND and PD.

BACKGROUNDThe cytosine arabinoside (Ara-C)-based chemotherapy is the major remedial measure for acute myeloid leukemia (AML). Deoxycytidine kinase (DCK) and cytidine deaminase (CDA) are the key enzymes in the metabolism of Ara-C. Many single nucleotide polymorphisms (SNPs) and haplotypes of DCK and CDA, which contribute to susceptibility to Ara-C, have been identified in Africans and Europeans. However, there has been no report about the relation among three SNPs in DCK (rs115543896, rs72552079, and rs111454937) and two SNPs in CDA (rs2072671 and rs60369023), and their clinical response to Ara-C for a Chinese population. In this study, we aimed to investigate whether these five SNPs are associated with the therapeutic outcomes of Ara-C-based chemotherapy regimens in patients with AML.
METHODSA total of 151 Chinese patients with AML were enrolled in our study. SNPs genotyping were performed using the MassARRAY system by means of the matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF-MS) method.
RESULTSThe results illustrated that DCKrs111454937 AA genotype was more frequent in patients with higher platelet count, and A allele frequency was significantly higher in the group £40 years, lower white blood cell (WBC) count patients group and the group with platelet counts > 60'10(9)/L. Meanwhile, both DCKrs72552079 TC (OR = 1.225, 95%CI = 1.225 - 9.851, P = 0.0192) and CDArs60369023 GA (OR = 9.851, 95%CI = 1.31 - 77.93, P = 0.0263) significantly improved Ara-C-based chemotherapy response. While DCKrs11554389 AA (OR = 0.147, 95%CI = 0.027 - 0.801, P = 0.0267) was associated with the decrease of Ara-C-based chemotherapy response.
CONCLUSIONIt is evident that the DCK and CDA polymorphisms might be the important markers for the AML patients' therapy outcomes in a Chinese population.

OBJECTIVETo investigate the effect of intracoronary adenovirus vector encoding hepatocyte growth factor gene (Ad(5)-HGF) on hematopoietic stem cells mobilization in patients with extensive coronary heart disease.
METHODSPatients with extensive coronary heart disease were treated with intracoronary infusion of adenovirus vector encoding hepatocyte growth factor (Ad(5)-HGF 5 x 10(9) pfu) gene plus stent implantation (n = 9) or equal physiological saline plus stent implantation (n = 9). Angioplasty and stent implantation was performed according to standard clinical practice by the femoral approach and blood samples were drawn from each patient at baseline before PCI, 6 to 24 hours and 6 days post procedure. The number of CD34(+), CD38(+) and CD117(+) cells in peripheral blood was analyzed by flow cytometer.
RESULTSThe number of circulating CD34(+) cells in Ad(5)-HGF gene treatment group 6 hours after procedure and the number of circulating CD117(+) cells 6 days post procedure were significantly higher in Ad(5)-HGF gene treatment group than those in the control group (0.104 +/- 0.082 vs. 0.022 +/- 0.012, P = 0.021) and (0.058 +/- 0.058 vs. 0.012 +/- 0.009, P = 0.034), respectively.
CONCLUSIONIntracoronary administration of Ad(5)-HGF could mobilize hematopoietic stem cells into peripheral blood and the consequent role of this observation on myocardial regeneration warrants further detailed studies.

Huangqi Guizhi Wuwu Decoction is a classic prescription in traditional Chinese medicine(TCM) and is known for its effects of tonifying Qi, warming the meridians, and promoting blood circulation to alleviate obstruction. It is primarily used to treat conditions characterized by Qi stagnation, Yang deficiency, and obstruction, and it exhibits pharmacological effects such as immune regulation, anti-inflammation, analgesia, protection of the cardiovascular and cerebrovascular systems, itch relief, reduction of frostbite symptoms, antioxidative stress, promotion of cell apoptosis, and kidney protection. In modern clinical practice, it is commonly used to treat acute myocardial infarction, sequelae of cerebral infarction, cervical spondylosis, frozen shoulder, lower limb arteriosclerosis, lower limb vascular disorders, peripheral neuropathy in diabetes, and lupus nephritis. Recent research has focused on the chemical components, pharmacological effects, and clinical applications of Huangqi Guizhi Wuwu Decoction. Based on the "five principles" of quality markers(Q-markers) in TCM, this study predicted and analyzed the Q-markers of Huangqi Guizhi Wuwu Decoction. It suggested that astragaloside Ⅳ, formononetin, kaempferol, quercetin, cinnamic acid, cinnamaldehyde, 6-gingerol, paeoniflorin, albiflorin, and gallic acid could serve as Q-markers for Huangqi Guizhi Wuwu Decoction. The findings of this study can provide references for quality control of Huangqi Guizhi Wuwu Decoction and the development of new Chinese medicinal formulations.
