Objective To study the effect of LDYS-14007 on JAK1-STAT3 signaling pathways.Methods MDA-MB-231 cells were treated with 10μmol,1 nmol LDYS-14007, and 10 μmol Tofacitinib,respectively.Western blot assay was used to determine the expression of JAK1,Phospho-JAK1, STAT3 and Phospho-STAT3.Results The absorbance value was linearly related to the concentration of protein C, The linear equation is A=0.0075C+0.0029, r=0.9976, The linear range of 1.08-5.08 mg/mL, With the increased concentration of LDYS-14007, the amount of Phospho-JAK1, Phospho-STAT3 were all gradually decreased.Conclusion LDYS-14007 leads to the levels of Phospho-JAK1 and Phospho-STAT3 decrease, which inhibits JAK1-STAT3 signaling pathway.LDYS-14007 may play an important role in the treatment of rheumatoid arthritis.

This research applied the theory of customer satisfaction model in the evaluation of the clinical information system. By means of qualitative and quantitative methods, it made validity and reliability measurement on the measurement tools in use. In addition, it extracted the structure validity of the factor regulating scale via a factor analysis, and developed the scale for clinical information system measurement These efforts provided the hospitals with the useful measurement tool to improve their information system, promoting positive and practical hospital informationziation.

Objective:To detect the mucin gene (MUC2,MUC5AC,MUC5B,MUC18 and MUC19)expression in the nasal polyps, allergic rhinitis (AR)and the normal nasal mucosa in human. To investigate the role and clinical significance of mucin gene in the pathogenesis of nasal polyps and AR patients .Method:We obtained samples from 35 cases of nasal polyps,18 cases of AR inferior turbinate and 18 cases of simple nasal septum deviation inferior turbinate. Specimens were analyzed with RT-PCR and Real-time FQ-RT-PCR.Result:The results of RT-PCR and FQ-RT-PCR showed that the expression of MUC5AC,MUC5B in nasal polyps and AR patients was significantly higher than that in normal mucosa(P<0.05). The expression of MUC5AC,MUC5B in nasal polyps was not significantly different from that in AR patients(P>0.05). The expression of MUC2, MUC18 in nasal polyps and AR was not significantly different from that in normal mucosa(P>0.05). And the results of RT-PCR for MUC19 expression in AR was higher than that in nasal polyps group and normal group(P<0.05 or P<0.01).Conclusion:MUC5AC and MUC5B are highly expressed in epithelium of human nasal polyps and AR, and they take part in mucus over-secretion in nasal polyps and AR.The expression of MUC19 in AR was higher than that in nasal polyps group and normal group. It indicates that the secretion of MUC19 in allergic rhinitis was on high level. There was no difference of the expression of MUC2 and MUC18 in nasal polyps group, AR group and in normal group.

Based on the assessment of protease (acid,neutral and alkaline protease) activity and amylase activity (?- amylase and ?- amylase),one Aspergillus oryzae K61 was selected from five wild Aspergillus oryzae which are original from spontaneous fermented soybean paste.One Aspergillus oryzae Y29 was screened with ultraviolet radiation.The Aspergillus oryzae Y29 can produce higher protease activity than original Aspergillus oryzae K61,and its hereditary stability is higher.Compared with Aspergillus oryzae 3.042,the Aspergillus oryzae Y29 showed higher protease activity,however,the both strains did not have significant difference on the amylase activity,growing speed of the strain and number of spore.Both strains were applied to producing soybean paste.The soybean that was produced by Aspergillus oryzae Y29 has full-bodied soybean paste flavor,and the soluble nitrogen (0.77g/100ml) is higher than the Aspergillus oryzae 3.042.

Objective To detect the expression of the tryptase in the plasma,and study the meaning in brain traumatic patients.Methods There were two groups:the brain traumatic group(40 patients)and the control group (20 health people).The content of plasma tryptase was determined by fluorescence enzyme immunoassay..Results The level of plasma tryptase had no statistical significance in control group(2.97 ±1.05)μg/L compared with the brain traumatic group(3.03 ±1.39)μg/L,however there had statistical significance comparing with sever brain traumatic patients(3.84 ±0.52μg/L)(t =3.32,P <0.05).4 cases of death in patients with severe head injury group content of tryptase (5.85 ±1.05)μg/L,which was significantly higher than the group of 16 cases of injury in severe head injury after 2 months still alive with the content of serum tryptase (2.49 ±0.52)μg/L,the difference was statistically significant (t =8.13,P <0.01).Conclusion The plasma tryptase level in sever brain traumatic patients increased significantly,and might be of importance for treatment strategies and prognosis.
