Objective To investigate the expression of proteinase active receptor 2(PAR2)protein in hepatocellular carcino-ma(HCC)and portal vessel tumor thrombosis(PVTT)to evaluate its clinical value.Methods Immunofluorescence,RT-PCR and Western blot were used to examine the expression of PAR2 protein in cancer tissue,tumor thrombosis and cancer-adjacent normal tissue from 21 patients with HCC.Results The expression pattern of PAR2 protein was different cancer tissue and cancer-adjacent normal tissue.PAR2 labeling index was significantly higher in cancer tissue and PVTT than cancer-adjacent normal tissue(P <0.05).Although PAR2 labeling index was lower in cancer tissue than in tumor thrombosis,no statistical significance was observed in PAR2 labeling index between them(P >0.05).Conclusion PAR2 is over-expressed in HCC and PVTT.PAR2 expression is re-lated with the development and progression of HCC.

Objective To observe effects of Xinfeng capsule(XFC)on depressive mood and serum cortisol in patients with rheumatoid arthritis and study its mechanism.Methods 76 RA patients were randomly divided into two groups.The treatment group(n=40)was treated with XFC,and the control group(n=36)with Zhengqing Fengtongning.The targets included clinical effects,symptom and sign,integral of quality of life,self-rating depression scale(SDS)and serum cortisol.Results The effects of XFC were similar to that of Zhengqing Fengtongning in the total effective rate,improving symptoms and sign,active index,etc.XFC was superior to Zhengqing Fengtongning in improving SDS standard score,the symptoms of splenic asthenia and quality of life(P

Objective:To observe the influence of Xinfeng capsule(XFC) on pulmonary HRCT images and cytokines(TNF-?,IL-10) in blood serum adjuvant arthritis rats.Methods:60 rats were averagely divided into normal control group,model control group,methotrexate(MTX) treated group,tripterygium wilfordii polycoride tablet(TPT) treated group, XFC treated group,12 in each.Except for the rats of normal group,the others were intracutaneously injected with 0.1 ml of Freund’s complete adjuvant in the right hindlimb.After 19 days,different drugs were given to all rats. Pulmonary HRCT images were obtained and the blood samples were reserved for assaying cytokines.Results:In model control group ,the lungs’ outlines weren’t clear and the blood vessels expanded with the edges of them being obscure and unregular. There were high density images shaped as rope and slip in lungs of model control group rats and the pleura near the images were a little thickening. In MTX treated group, there were high density images shaped as slice along pulmonary veins. The veins of the blood vessels were obscure and the edges were unclear. In TPT treated group,there were multiple high density images shaped as tubercle and slice and the boundary were not clear. In XFC treated group, the lungs’ outlines were clear and the veins were well-distributed. High density images shaped as spot were found in part lungs. Compared with normal control group,tumor necrosis factor-?(TNF-?) in blood serum ascended obviously in model control group(P0.05).Conclusion:XFC eliminates swelling by down-regulating the levels of TNF-?, up-regulating the levels of IL-10, restraining the inflammatory reaction.In adittion,cytokines participated in forming pulmanory fibrofication.So the changes of pulmanory HRCT images were also improved at the same time.

Objective To explore the trend of Th_1/Th_2 bias in Hashimoto thyroiditis(HT)and their effects on the pathogenesis of HT.Methods The proportion and mean fluorescence intensity(MFI)of CCR5 and CD30 were examined on peripheral T lymphocytes by flow cytometry in patients with Hashimoto thyroiditis(HT)(n=21)and healthy controls(n=45).Results The proportion of both CD4~+CCR5~+and CD~+4 CD30~+ cells were significantly increased in HT group(P

BACKGROUND:Immunotherapy with autologous immune cel s has been developed as a major adjuvant therapy for malignant tumors, but its mechanism of action has not been elucidated. OBJECTIVE:To investigate the relationship between cytokine-induced kil er cel secretion and apoptosis in human liver cancer stem cel s. METHODS:Human liver cancer stem cel s, HepG2 cel s, were isolated and enriched using serum-free suspension method. The peripheral blood mononuclear cel s from patients with liver cancer were induced byγ-interferon, CD3 monoclonal antibody and recombinant human interleukin-2 to form kil er cel s. Passage 1 liver cancer stem cel s were divided into control group (culture alone) and experimental group (co-culture of cytokines-induced kil er cel s and human liver cancer stem cel s). At 48 hours after culture, apoptosis in human liver cancer stem cel s was detected using flow cytometry, and expression of caspase-3 mRNA and protein was detected using RT-PCR and western blot, respectively. RESULTS AND CONCLUSION:The apoptotic rate in the control group was significantly lower than that in the experimental group (P<0.05). The expressions of caspase-3 at mRNA and protein levels were both higher in the experimental group than the control group (P<0.05). Experimental findings show that cytokines-induced kil er cel s can significantly promote apoptosis in human liver cancer stem cel s, and up-regulate the caspase-3 mRNA and protein expressions dramatical y.

OBJECTIVE:To study the pharmacokinetic characteristics of Recombinant hirudin enteric-coated capsule by single and multiple administration in Beagle dogs. METHODS:12 Beagle dogs were divided into single ig group and single iv group by random control method,6 in each group. Recombinant hirudin 0.2 mg/kg was intragastrically administrated or intravenously inject-ed,blood sample was collected;after 2 weeks of cleaning,12 dogs were intragastrically administrated recombinant hirudin 0.2 mg/kg,for 7 d. Sample blood was collected,referred to multiple ig group. Recombinant hirudin concentration in plasma was deter-mined by enzyme-linked immunosorbent assay,and pharmacokinetic parameters were calculated by DAS 2.0 software. RESULTS:The results showed that pharmacokinetics by ig and iv recombinant hirudin in Beagle dogs fitted to two-compartment model,abso-lute bioavailability of ig Recombinant hirudin enteric-coated capsule was(14.908±1.868)%;the pharmacokinetic parameters in sin-gle ig group and multiple ig group were tpeak of(2.105±0.243),(3.000±0.000)h,t1/2β of(8.660±2.965),(14.870±2.710)h, cmax of(10.700±0.872),(12.05±1.587)ng/mL,AUC0-1440 min of(55.250±4.386),(58.978±6.002)ng·h/mL,without statistical significances in two groups(P>0.05). CONCLUSIONS:The ig Recombinant hirudin enteric-coated capsule can be absorbed into the blood to a certain extent. There is no accumulation for ig Recombinant hirudin enteric-coated capsule for several days,and it dose not change the pharmacokinetic characteristics.

All the subjects have accepted the routine anti-cancer therapy. Observe the index of cancer pain, hemogram and the livability. Results (1) The rate of occur leucopenia in these two groups is 30.00% and 63.64% respectively, P

Summary Vertical nystagmus is a vertical nystagmus caused by structural abnormalities and/or dysfunction of the central vestibular system and observed in situ in the center of the eyeball. There are two kinds of nystagmus （UBN） and downbeat nystagmus （DBN） according to the direction of nystagmus. The diagnosis of UBN is mainly made by naked eye or electronystagmography/viewer. It is a common neuro-ophthalmologic sign in the field of vestibular medicine. In this paper, the mechanism of vertical nystagmus formation and the location of lesions were briefly introduced, in order to provide help for the diagnosis and treatment of Vertigo.
