Chinese Journal of Medical Imaging 2013;(6):428-430
Purpose To evaluate the application value of rapid exchange method in transnasal intestinal obstruction catheterization. Materials and Methods Fifty-eight patients with adhesive intestinal obstruction underwent transnasal catheterization under X-ray fluoroscopy, of which 31 cases were treated with rapid exchange catheterization method (group A) and the other 27 cases with traditional catheterization method (group B), success rate, operation time and complications were compared between the two groups. Results Catheterization success rate of group A and group B were 96.77%(30/31) and 77.78%(21/27) respectively, which was significantly higher in group A than in group B (χ2=4.907, P<0.05);operation time of group A and group B were (28.2±12.3) min and (25.4±15.7) min respectively, and the difference between them was not statistically significant (t=1.219, P>0.05); no operation associated injury occurred in group A and only one case in group B (3.70%) resulted in bilateral nasal edema with a small amount of bleeding because the operating time was too long, complication rate between the two groups was also not statistically significant (P>0.05). Conclusion Rapid exchange method can improve the success rate of transnasal intestinal obstruction catheterization, but the operation time and complications are comparative to those of the conventional method.

Journal of Zhejiang Chinese Medical University 2015;(2):95-97
Objective] To study emotional counterbalance therapy which is used in depression treatment ,it plays an important role in the treatment of emotional disorders. [Method] With the research methods of taking depression for example ,through the sad,fear of these two emotional factors to explore the pathogenesis of depression,and analyze“happiness restrains sadness“ and“thought restrains fear”in the emotional counterbalance therapy, which are used in the depression clinical application.[Result]Emotional counterbalance uses one or more of the emotions to regulate ,control,overcome the other one or more negative emotions,which based on the restriction among the five elements theory is a kind of psychological therapy.Sadandfearare the most common chief complaints in depression which belong to the emotional depression in depression disease of Chinese medicine. On the basis of “sad doing harm to the lungs”and “dread doing harm to the kidneys”,lung,kidney and depression etiology,pathogenesis,symptoms are closely related. This reflects the lung,kidney play an indispensable role in the treatment of depression. It has significant curative effects to apply the theory of emotion counterbalance,such as happiness restrains sadness,thought restrains fear to cure diseases. At the same time,with a relaxed and pleasant mood,actively guiding to help thinking is also the treatment of depression,pessimistic disappointment medicine.[Conclusion] According to the restriction among five elements theory,to use the relation and restriction between emotion and five zang-organs to regulate emotional disorders can restore to the normal balance,which is an effective psychological treatment for emotional disorders.The therapy should be used alone or combined with traditional Chinese medicine treatment in different situations to relive the treatment effect.
4.Preparation of recombinant human soluble TRAIL and its inducing effect on apoptosis of tumor cells by TRAIL combined with bortezomib
Chinese Journal of Pathophysiology 2015;(11):1933-1942
[ ABSTRACT] AIM:To construct a prokaryotic expression plasmid to produce recombinant human tumor necrosis factor-related apoptosis-inducing ligand ( TRAIL) and to verify the biological activity of TRAIL.METHODS: The pro-karyotic expression plasmid pET-28a (+)-TRAIL114-281 was constructed.Human soluble TRAIL was obtained through opti-mized inducing protein expression and purification conditions.The biological activity of TRAIL was verified by CCK-8 as-say.The apoptosis-inducing effect of TRAIL alone and/or in combination with proteasome inhibitor bortezomib ( Velcade, PS-341) on the tumor cell lines H460 ( TRAIL-sensitive) and K562 ( TRAIL-resistance) for 24 h was determined.The ap-optotic rates of the cells were analyzed by flow cytometry with Annexin V-FITC/PI staining.The activities of caspase-8,-9 and -3 in the cells were detected by colorimetric method.The protein expression of Bax, Bcl-2 and cFLIP was measured by Western blot.The expression of DR4 and DR5 in the H460 cells and K562 cells after treated with bortezomib for 24 h was detected by flow cytometry.RESULTS:The recombinant human soluble TRAIL protein with stable bioactivity was success-fully acquired, which induced apoptosis in H460 cells and K562 cells.After treatment with different concentrations of TRAIL, the apoptotic rate of H460 cells was significantly increased with the increase in the concentration of TRAIL ( P<0.05), but the apoptotic rate of K562 cells was not affected by the increasing TRAIL concentration.Apoptotic rate in com-bination group was obviously higher than that in single group ( P<0.05 ) .In the process of apoptosis, the activities of caspase-8,-9 and -3 in H460 cells and K562 cells were both increased.The expression of Bcl-2 and cFLIP in treatment groups ( especially the combination group) was decreased compared with control group.No significant change of the Bax expression level was observed.The expression of DR4 and DR5 in the H460 cells and K562 cells was significantly up-regu-lated after treated with bortezomib ( P<0.05 ) .CONCLUSION: Bortezomib combined with recombinant human soluble TRAIL synergistically induces apoptosis in tumor cell lines H460 and K562 through initiating intrinsic apoptotic pathways by up-regulating death receptors DR4 and DR5, and reducing the expression of antiapoptotic proteins Bcl-2 and cFLIP.

Chinese Journal of Laboratory Medicine 2003;0(11):-
Objective To prepare monoclonal antibody (mAb) against recombinant human cardiac troponin I(cTnI).Methods The full-length gene encoding human cardiac troponin I (cTnI) was synthesized chemically and inserted into expression plasmid pBV220 to construct recombinant plasmid p pBV220/cTnI. The recombinant plasmid was transformed into E.coli DH5? which then expressed cTnI. The immunological activity of the expressed cTnI was analyzed by Western blot. Recombinant human cTnI protein was used as antigen to immunize BALB/c mice. Monoclonal anti-bodies against cTnI were prepared by normal hybridoma technology. The relative affinity of mAbs was determined by ELISA. Specificity of mAbs was analyzed by Western blot.Results Human cTnI gene was synthesized and confirmed by DNA sequencing. Positive recombinant clones were identified by restriction enzyme digestion analysis and DNA sequencing. Western blot analysis showed that the cTnI protein could be recognized by an anti- cTnI antibody. Two hybridmas producing antibodies against cTnI were obtained. IgG isotypes of two mAbs were IgG2a and IgG2b. Western blot showed that the antibodies were specific for cTnI. Neutralisation test showed that these mAbs could be evidently neutralized by cTnI.Conclusion The recombinant expression plasmid of cTnI was constructed successfully and expressed in E.coli. The method of EL ISA established to test serum cTnI is to clinically useful. The cTnI mAb which using cTnI as antigen prepared in this paper can be used for cTnI immunoassay in vitro.
