The immunopathogenosis of chronic hepatitis B is complex. The host immune response plays an important role in determining the turnover of chronic hepatitis B, which is impacted by HBV, host immune system and liver microenvironment. In clinical practice, interferin-α (IFN-α) which has both anti-virus and immuno-regulatary effect wins the advantage over nucleoside analogue. During treatment with INF-α, quantitative HBsAg can predict therapy early which can make physicians modulate individual therapy strategy and achieve better curative effect. To better understand the anti-HBV immune responses to chronic hepatitis B, scientists hope to explore more effective and potential immunotherapeutic strategies against this disease.

Objective To evaluate the statues of P-selectin and chang of D-dimer in vivo in patients with deep venous thrombosis(DVT)and to observe how to vary under interneving of medicines.Methods P-selectin and D-dimer of fourty patients and twenty normal subjects were fluo-rescencelabled with its corresponding monoclonal antibodies by flow cytometry(FCM)and immune method respectively.Results In the early stage,P-selectin and D-dimer of patients with DVT is higher than that in normals,and they significantly decreased in different time after patients were treated.Compared with patients who were used on-sodium ozagrel,patients used sodium ozagrel have different P-selectin(P＜0.05),but D-dimer was similar(P＞0.05)after fourteen days.One month later,P-selectin and D-dimer of DVT patients were lower.However,the positive rate of P-selectin of DVT was still higher than normal subjects.Conclusions The platelet has been actived in vivo in patients with DVT,so do fibrinolysis.Sodium ozagrel can decrease the action of platelet.P-selectin and D-dimmer may be used in diagnose.Post-discharge patients are still high-risk group and must be followed-up regularly.

The effects of nitroquine on the sporogonic development of Plasmo-dium yoelii were observed under electron microscopy. The female mosquitoes were fed directly with 10% sucrose solution containing 0.1%Nitroquine.It was found that the oocysts were smaller and markedly degenerated as compared with that of the control. The surface of the oocysts was rough and uneven. Under a transmission electron microscope, the cytoplasm of the affected oocysts contained vacuoles; the membane of mitochondria and uncleus was damaged; and the number of residual bodies increased.No sporoblast formation was seen in most of the affectes oocysts. The nuclear membrane of the degenerated sporozoites was thickened and the density of nuclear matrix decreased markedly as compared with that of the control. These results indicate that the nucleus and the membrane are mainly affected during the sporogonic development of P. yoelii by nitroquine.

Anopheles Stephensi,infected with Plasmodium yoelii.was fed on 10% sucrose solution containing 1%.difluoromethylornothine(DFMO)to induce the degeneration of its oocysts.On the 11th day after infection,the effects of hemocytes on the normal and degenerated oocysts were observed wtih transmission electron microscopy.In the control group.no hemacytes could be found around the normally-developed oocysts except those degenerated ones.In the DFMO group,all the oocysts underwent degeneration in various degrees and some of them were melanized.All the oocysts were attached by one or more hemocytes which belonged to the category of granulo-cytes morphologically.There were many granules with microtubular construction in the cytoplasm of the hemocytes and in the spaces between a hemocyte and an oocyst.The findings indicate that the degeneration of oocysts can exert a taxic effect on hemocytes and the latter may release the granules and possibly other substances to result in the encapsulation and melanization of the oocysts.

With techniques of biochemical isolation and pruification, a semi-purified preparation of new born calf liver (BLS) with the peculiarity of low molecular weight has been found to have tumor surppressor activity inhibiting selectively the growth of murine myeloid leukemic cell (L801). But its effect is less marked against normal bone marrow granulocyte / macrophage progenitors in in vitro liquid or agar culture. Mice after inoculation of L801 cells died within 15 days due to development of leukemia. After consecutive injections of BLS, 25% - 53.8% of treated mice survived. Furthermore, it has been found that the survival rate was raised from 50% to 66% when Cyclophosphamide was first injected in the dose of 300?g / kg body weight once, followed by the consecutive injections of BLS. NO pathological changes have been observed in the mice which survived longer than 100 days after inoculation of L801 leukemic cells.

Objective To study the relationship between microalbuminuria and cardiac diastolic function in patients with type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD). Methods A total of 262 patients with T2DM and NAFLD were included in this study. Patients were divided into normal group (n=106) and abnormal group (n=156) according to their cardiac diastolic function. Data of waist circumference (WC), low density lipoprotein cholesterol (LDL-C), triglyceride(TG), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), fasting insulin level (FINS), insulin resistance index (HOMA-IR), glycosylated hemoglobin (HbA1c), glomerular filtration rate (GFR), C reactive protein (CRP), urinary microalbuminuria excretion rate (UAER), left ventricular myocardial quality index (LVWI) and liver fat content (LFC) were compared between two groups. All patients were divided into four groups according to data of UAER and GFR:group A[UAER<20μg/min and GFR≥90 mL/(min · 1.73 m2)], group B [UAER<20μg/min and GFR<90 mL/(min·1.73 m2)], group C [UAER≥20μg/min and GFR≥90 mL/(min·1.73 m2)], and group D [UAER≥20μg/min and GFR<90 mL/(min · 1.73 m2)]. The differences between the relevant indicators were analyzed between groups. Logistic regression analysis was used to compare UAER between normal group and abnormal group. Also the relationship between the related factors and cardiac diastolic function was compared between these two groups. Results For abnormal group, TG, SBP, HOMA-IR, CRP, UAER, LVWI and LFC were significantly higher, and GFR was significantly lower, than those of normal group (P<0.05). There were no significant differences in other indicators between two groups. Values of peak early/late diastolic filling velocity (E/A) showed a reduction trend in order in A, B,C and D groups (P<0.05). Values of LVWI showed a increasing trend in order in four groups (P<0.05). Values of LFC were significantly higher in C and D groups compared with those of A and B groups (P<0.05). There was no significant difference in LFC between A group and B group. The GFR<90 mL/(min·1.73 m2)was an independent risk factor for cardiac diastolic function in normal group of UAER, and higher UAER was an independent risk factor for cardiac diastolic function in the abnormal group of UAER. Conclusion There is obviously reduced cardiac diastolic function in patients with T2DM and NAFLD and microalbuminuria. When UAER≥20 μg/min, the higher UAER is an independent risk factor for reducing diastolic cardiac dysfunction.

The percentage of sporozoites developed in exoerythrocytic forms in the rats treated intravenously with cyclophosphamide 24 hrs before inoculation of sporozoites was higher than that in untreated controls, so was the mean size of exoerythrocytic form. Cyclophosp-hamide could decrease the sensitivity of hepatocytes to the vector's tissues inoculated together with sporozoites, thus decreasing the incidence of cloudy swelling of hepatocytes induced by the vector's tissues and inhibiting the white blood cells infiltration induced by the ruptured mature exoerythrocytic form.The fact that cyclophosphamide might enhance the invasion of sporozoites into the hepatocytes indicates that the phagocytic activity of Kupffer's cells to destroy the sporozoites might be inhibited by cyclophosphamide.

5-HT immunoreactive cells(EC cells)in the gastrointestinal tract were studiedby immunogold silver staining method and PAP method in sixty human fetuses aged8-38 weeks of gestation.The results indicated that the appearance of EC cells wasas early as 8 weeks of gestation in the epithelium of duodenum.After 12 weeks ofgestation,the EC cells can be found in the whole human fetal gut.The number ofEC cells(EC cells with visible nucleus per visual field)at all period of gestationalways decreased in an order from the mucosa of duodenum,jejunum,ileum,ap-pendix,colon and stomach respectivly.EC cells in the mucosa of antrum often po-ssessed long processes contacted with other types of glandular cells.The EC cellswere open typed cells except those in the fundic mucosa.Grouped EC cells can alsobe seen in the mucosa of appendix and the intestinal glands.

p27kip1 maps 12p13 and it has two exons. p27 not only inhibits the activation of acyclin dependent kinases, but also surpress the activity of ctivated cyclin CDKs. p27 plays a key role in the regulation of cell cycle progression, and relates to cell differentiation and apoptosis. Loss of p27 protein or lower level of it is prevalent in digestive tumors, and reduction of p27kip1 protein indicates malignant prognosis.
