Objective To study the relation between Child Turcotte classification and pathology, diagonsis, prognosis and fibrosis index as well as its significance. Methods The levels of hyaluronic acid(HA), type Ⅲ procollagen(PCⅢ), Laminin(LN) and type Ⅳ collagen(Ⅳ C) were detected by enzyme linked immunoadsordent assay(ELISA) or radioimmunoassay(RIA). Pathomorphology was observed in 68 patients with cirrhosis. Results Level of HA in serum was positively correlated with cirrhotic severity, but other fibrosis indexes could not reflect cirrhotic severity. Child Turcotte classification was concordant with the pathological changes. The concordance rate of Child Turcotte classification B or C patients with pathologic diagnosis was up to 97.8%. The recovery rate of Child Turcotte classification A patients was up to 95.5%. Fatality rate of Child Turcotte classification C patients was up to 96.9%. Conclusion Child Turcotte classification is closely correlated with the severity of hepatic fibrosis, severity of pathological changes in liver and prognosis of patients. It is of clinical value in the reflection of severity of hepatic cirrhosis.

Flowering, the floral transition from vegetative growth to reproductive growth, is induced by diverse endogenous and exogenous cues, such as photoperiod, temperature, hormones and age. Precise flowering time is critical to plant growth and evolution of species. The numerous renewal molecular and genetic results have revealed five flowering time pathways, including classical photoperiod pathway, vernalization pathway, autonomous pathway, gibberellins (GA) pathway and newly identified age pathway. These pathways take on relatively independent role, and involve extensive crosstalks and feedback loops. This review describes the complicated regulatory network of this floral transition to understand the molecular mechanism of flowering and provide references for further research in more plants.

Epithelial cellular adhesion molecule (EpCAM)is a transmembrane glycoprotein expressed in epithelial tissues and most epitheli-al-derived malignant tumors.EpCAMis associated with cell adhesion,migration,proliferation,and differentiation,as well as tumor devel-opment and progression.In recent years,EpCAMhas been identified as a stem cell marker of hepatocellular carcinoma (HCC).This paper elucidates the roles of EpCAMin the diagnosis,treatment,and prognosis of HCC,which shed light on the potential molecular targeted thera-py in future.

Objective To investigate the cardiac affects of esophageal dilatation and stent implantation and its possible pathogenic mechanism. Methods One hundred patients who underwent esophageal dilation or stent implantation had investigeted with Hotter tape recorder, vectorcardiogram, oxygen saturation and cardiac enzymes checked at the time prior to. during and after the procedure respectively. Results During the procedure, incidence of frequent ventricular premature beats was 66%, paroxysmal ventricular tachycardia 9 cases; frequent atrial premature heats 73 cases, paroxysmal supraventricular tachycardia 21 eases, myocardial ischaemia 17 cases and hypoxia 69 eases with significant differences comparing with those prior to the procedure(9 cases; 0 case; 7 cases; 0 case; 0 case and 9 eases respectively) but all above changes as well as cardiac enzymes recorded 24 hours after the procedure had no statistical significance comparing with those prior to the procedure. Conclusion There is a high incidence of cardiac arrhythmia and myocardial ischaemia at the time of dilatation and stent implantation. However, most of these changes can subside without intervention 24 hours after the procedure. Pathogenic mechanisms involved may be related to hypoxia duo to the pain provoked by the procedure suggesting close observation is needed during the operation.

Endoplasmic reticulum stress(ERS) is a kind of subcellular pathological state,and associated with many diseases.Recently,the research of ERS on chondrocyte is at the beginning stage,and may be involved in pathogenisis of rheumatoid arthritis(RA) and osteoarthritis(OA).It has been proved that ERS can interfere the differentiation of chondrocyte,decrease the synthesis of abnormal protein,attenuate the injury of cell.But overreaction of ERS can cause chondrocyte apoptosis through an independent pathway without of Fas and NO.There are three signal transmission passages in ERS:ATF-6(activating transcription factor 6)、Ire 1(inositol-requiring 1)and PERK(PKR-like ER kinase).The three protein molecules activate apoptotic genes by TRAF-2(TNF receptor-associated factor 2)and GADD153(growth arrest and DNA-damage-inducible gene 153),initiate the chondrocyte apoptosis.Therefore,ERS may effect the pathogensis of RA and OA by modulating chondrocyte function and inducing apoptosis,but more research are needed to reveal the mechanism.

Objective To study features and significance of clinical stages and types of severe acute respiratory syndrome (SARS). Methods The clinical features of 330 patients with SARS were analyzed by SPSS 11.0 and SDAS software packages, and the standard for classification of clinical stages and types of SARS were studied. Results The disease course of SARS could be divided into four stages, namely, incubation stage, initial stage, climax stage and convalescence stage. The period of incubation stage was 1~12 (5.70?2.45) days. The initial stage was the pathoformic phase during 1 st~10 th (3.98?2.48) days after the onset. The fever was the first symptom and there were usually no catarrhal symptoms. Meanwhile, no abnormality was found in the chest X-ray examination. The climax stage included 3 sequential phases of pulmonary inflammatory exudation, pulmonary tissue consolidation and ARDS or multi-organ failure. In the phase of pulmonary inflammatory exudation, there were serious cough, mild shortness of breath and hypoxemia. Furthermore, chest X-ray examination showed that there was exaggeration of lung markings, haziness or patchy opacity. In the phase of pulmonary tissue consolidation, type I respiratory failure was usually seen in the patients. Shortness of breath and hypoxemia became more serious. Chest X-ray examination showed that the area of consolidation continued to enlarge to include the entire lung. The convalescence stage usually appeared 3 weeks after the onset and lasted for 5～56 (24.37?8.81) days. This stage could further be divided into phase I (complete recovery) and phase II (possible existence of pulmonary fibrosis). SARS could be clinically classified into mild type (ordinary type), severe type and extremely severe type (fulminant type) with a mortality of zero, 5.76% and 61.54%, respectively. There were very great differences in clinical features in three types of SARS. Conclusions SARS could be divided into the incubation stage, initial stage, climax stage and convalescence stage. The climax stage included 3 phases, i.e. pulmonary inflammatory exudation, pulmonary tissue consolidation, and ARDS or MOF. The convalescence stage could be divided into phase I (complete recovery) and phase II (possible existence of pulmonary fibrosis). SARS could be classified as mild type, severe type and extremely severe type.

Objective To analyze the clinical features of severe acute respiratory syndrome(SARS) in order to look for premonitory signs of deterioration of patients suffering from SARS. Methods Three hundred and thirty patients with SARS referred to the Chinese Disease Center(CDC) in Beijing were studied retrospectively by SPASS and SDAS software. The data reviewed included clinical manifestations, laboratory findings, and X-ray pictures. Results The prognosis of mild SARS was good with a cure ratio of 100%. Chest radiography revealed opacity or small subtle opacity in lung periphery in 53.1%, there were no signs of acute lung injury in 67.2%, and the opacity disappeared rapidly. In patients with severe SARS, the disease course was longer(41.3?5.6day), the duration of high fever was longer (8.66?3.22day), with the highest temperature reaching 39.04?0.71℃. The duration of respiratory insufficiency was also longer(8.80?4.56day), and 71.8% of them manifested acute lung injury, involving a large area of the lung, with central lesions in 21.8% or mixed in 50%. The opacity was denser, and it took a longer period to resolve. The levels of LDH, HBDH, ESR and CK-MB were high, with HBDH/LDH ratio ranged from 0.8 to 1.0. The mortality was high(14.54%). Logistic regression analysis showed that the premonitory mode of deterioration of the disease was P y=1=? s /(1+? s)(S=-10.598+0.102A+0.592B+0.077C+0.494D), with sensitivity of 86.67%, and specificity 80%, and it was correlated with age, duration of respiratory insufficiency, ESR, and duration of high temperature. Conclusions The premonitory mode of deterioration of SARS is a new, simple, low-cost, biomathematically and pathophysiogically based index. It allows the prediction of deterioration and severity of SARS.
