Objective To investigate the clinicopathological features,diagnosis and differential diagnosis of nasopharyngeal carcinoma.Methods Analyzed 96 cases of nasopharyngeal carcinoma clinicopathological characteristics and reviewed the literature.Results Ninety-six cases were non-keratinizing nasopharyngeal carcinoma, the male-to-female ratio was 2.6:1. The mainly clinical symptoms was purulent bloody rhinorrhea and neck mass,which nasal endoscope could be seized,the mass lied in lateral wall of pharynx nasalis,tumor cells was broad-spectrum positive for CK and negative for LCA.Conclusions Nasopharyngeal carcinoma is a common disease in this region,if nasal endoscope biopsy less accurate or the performance is not typical,may be confused with reactive lesion and lymphoma,which should be combined with clinical data,endoscopic features and immunohistochemical characteristics to identify.

Atherosclerosis is a chronic inflammatory immune disease,which is one of the causes of human lower limb disability.Dendritic cells are the most powerful professional antigen presenting cell in immune system,and dendritic cells have the dual role of immunogenicity and tolerability.As a professional antigen presenting cell,the immunogenicity of dendritic cells present self abnormal antigen and course immune system disorder,which may be one role of dendritic cells participate in atherosclerosis.However,the tolerability of dendritic cells can course the generation of immune tolerance,which makes dendritic cells exert a regulatory role in atherosclerosis.This paper makes an introduction about how dendritic cells are involved and play a regulatory role in the pathogenesis of atherosderosis.

A high performance liquid chromatography (HPLC)has been used to determine aconitine in the sample of rabbits. Kinetics of degradation of aconitine in vitro was studied. The degradation of aconite from the poisoned specimens (coagulated blood, liver) treated differently in vitro was characterized by pseudo-secondorder kinetics. The K. of aconitine in these samples was the biggest in the fixed section of 4% aqueous solution of formaldehyde (1.5619, O.7728?g/d), bigger in the fixed section of 95% alcohol(0.4891, 0.07536?g/d) and the smallest in the refrigerator at 4℃ (0.06372, 0.03903 ?g/d), respectively. That is, aconitine in the poisoned samples was decomposed slowly in the refrigerator and secondly in the fixative of alcohol. Amount of aconitine might be extrapolated from the result of examination of specimens taken from the subject after poisoning or killing by the poison, using the kinetics equation.

Objective To investigate the clinical efficacy of psychological intervention combined with valsartan and Benner Pury in the treatment of congestive heart failure (CHF). Methods 100 patients with congestive heart failure treated in our hospital from January 2015 to October 2016 were selected and randomly divided into the control group and the experimental group, with 50 patients in each group. Patients in the control group were treated with Benner Pury, the experimental group was given valsartan and Benner Pury combined treatment, and psychological intervention, pay attention to the psychological state of patients. The clinical indexes of the experimental group and the control group were compared and analyzed. Results After the corresponding treatment, the effective rate of treatment in the experimental group was 96%, and the effective rate of the control group was 82%. The effective rate of the patients in the control group was significantly lower than that in the experimental group, with statistical difference (P<0.05). The incidence of adverse reactions in the experimental group was 8%, and the fatality rate was 10%. The incidence of adverse reactions in the control group was 10%, and the fatality rate was 12%. There was no significant difference between the experimental group and the control group in the incidence of adverse reactions and mortality, and it was not statistically significant, and could be compared. Conclusion The clinical effect of psychological intervention combined with valsartan in the treatment of congestive heart failure, Benner Pury good, can improve the treatment efficiency to a certain extent, high safety, is further applied in clinical significance.

Objective To analyze the relationship between serum HBV-DNA and hepatic fibrosis in patients with hepatitis B. Methods Serum HBV-DNA load and hepatic fibrosis hyaluronic acid (HA),Ⅲ procollagen N terminal peptide(PⅢNP),laminin (LN),Ⅳ collagen(Ⅳ-C)of 154 cases were detected by real-time fluorescence quantitative PCR and chemiluminescence method. Statistical analysis of the correlation between HBV-DNA load and hepatic fibrosis indicator was performed.Results The data of HBV-DNA load after taking lg value was 5.49±1.39;The serum concentration of hepatic fibrosis HA was (166.95±148.20)ng/mL,PⅢNP was (12.14±7.37)ng/mL,Ⅳ-C was (65.29±45.48)ng/mL,LN was (59.52±35.67)ng/mL.The difference between experimental group and control group in hepatic fibrosis was significant(P <0.05).Serum HBV-DNA only correlated with LN(r=0.284,P =0.015).Conclusion There is no significant correlation between serum HBV-DNA and hepatic fibrosis in hepatitis B pa-tients.Anti-fibrosis treatment should also be strengthened for hepatitis B patients in the course of antiviral treatment.

The neuroendoerine cells (NE cell) of the lung have been studied in 61 human fetuses by silver stain, immunocytochemical method and electron microscopic technique. The NE cells are mainly located in epithelium of conducting portion with various appearance. Some NE cells are neuron like with several processes. The 5-HT positive NE cells are often found in the epithelium of the primitive alveoli with pyramidal, squamous and tadpole-like appearance. Based upon their ultrastructure, the NE cells are rich in organelles and dense core vesicles (DCV). The NEB is often covered by a layer of cuboidal cells, but no nerve fibers are found among the cells in the NEB.The argyrophil cells usually appear in the 12th week, and reach the maximum number by 20th week. Before the 19th week, the argyrophil cells in the upper segment of the conducting portion are more numerous than those in the lower segment, while after 19th week the condition is just reverse. A regression curve made from the number of argyrophil cells and the thickness of intrapulmonary arteries in different fetal ages shows positive correlation.

Objective:To study the preventive and therapeutic effects of Acalypha decoction on 2,4,6-trinitrobenzene sulfonic acid induced ulcerative colitis(UC) in rats.Methods: Totally 70 male SD rats were equally randomized into 7 groups, and UC was induced by intrarectal administration of TNBS (125 mg/kg in 50% ethanol). Six hours later the rats were given 3 different doses of Acapha decoction (2.5, 6.5, 9.5 g crude drug/kg body weight) daily for 10 d.Some rats were pretreated with Acalypha decoction (6.5 g crude drug/kg body weight) 3 d before the colitis was induced. Sulfasalazine was used as the standard drug for comparison. The efficacy of Acalypha decoction was assessed through the following parameters: bodyweight loss, diarrhea and bloody stool, macroscopic score,histological changes,and MPO activity in colon tissue. Results: Acalypha decoction treatment(9.5 g/kg, 6.5 g/kg) and prevention administration (6.5 g/kg) significantly inhibited the bodyweight loss and occurrence of diarrhea and rectal bleeding in the rats(P

In inflammatory bowel disease, the experimental model s have been proven to be important tools to investigate the potential therapeuti c agent and to study the mechanism of pathogenesis. Literatures available were r eviewed on the methods of induction, characteristic and availability of all kind s of chemically induced IBD animal models. It would provide some information for selection of the experimental model in pharmacology and pathogenesis study.

Influenza virus is a continuous and severe global threat to mankind.The continuously re-emerging disease gives rise to thousands of deaths and enormous economic losses each year,which emphasizes the urgency and necessity to develop high-quality influenza vaccines in a safer,more efficient and economic way.The influenza subunit and VLP vaccines,taking the advantage of recombinant DNA technologies and expression system platforms,can be produced in such an ideal way.This review summarized the recent advancements in the research and development of influenza subunit and VLP vaccines based on the recombinant expression of hemagglutinin antigen (HA),neuraminidase antigen (NA),Matrix 2 protein (M2) and nucleocapsid protein (NP).It would help to get insight into the current stage of influenza vaccines,and suggest the future design and development of novel influenza vaccines.
