Chinese Journal of Organ Transplantation 2005;0(08):-
Objective To study the relationship of cytokines and cytokine receptors gene polymorphism with acute rejection in kidney transplantation recipients,whose 21 single nucleotide polymorphisms in 5 kinds of cytokines and their receptors were tested with cytokine oligonucleotide array.Methods According to the allele sequences of 21 gene polymorphisms of IL-4,IL-6,IL-10,TNF-?,TGF-?_1 and their receptors,58 oligonucleotide probes were synthesized. A pair of group special primers labeled by the Cy5 were designed and were used in the PCR. The labeled PCR products with Cy5 were hybridized with array. The signals were scanned by a scanner and analyzed by image software. Genomic DNA samples from the peripheral blood lymphocytes of 144 kidney transplant recipients were tested by this array. The distribution of 21 single nucleotide polymorphism in cytokines and cytokine receptors was compared between two groups according to the presence or absence of acute renal rejection.Results In recipients,the gene polymorphism distribution in rejection group and non-rejection group showed significant difference (P

Chinese Journal of Biochemical Pharmaceutics 2017;37(3):237-239
Objective To observe the effect of aerosol inhalation of ambroxol combined with budesonide on neonatal pneumonia .Methods 66 infants with pneumonia treated were enrolled in this study.The patients were divided into observation group ( n =33 ) and control group ( n =33 ) according to the random number method.The treatment group were treated with ambroxol combined with budesonide and the control group were treated with budesonide.The two groups of infant lung function, clinical outcomes and blood flow were compared.Results The total effective rate (93.94%) in the observation group was significantly higher than that in the control group (45.45%), there was significant difference between the two groups (P<0.05).After treatment, FEV1 and PEF in the two groups were significantly higher than those before treatment, the observation group [(95.21 ± 7.69)%, (93.21 ±7.89)%] were significantly higher than those of the control group[(87.03 ±7.23)%, (84.55 ±7.45)%], the differences between the two groups were statistically significant (P<0.05).The OI of the two groups was significantly higher than that of the control group and the OI of the observation group was significantly higher than that of the control group.PaCO2 of the two groups decreased significantly and the PaCO2 of the observation group was significantly lower than that of the control group, the difference was statistically significant ( P<0.05 ).Conclusion The combination of ambroxol and budesonide is effective in the treatment of neonatal pneumonia.It can effectively improve the infant pulmonary function, shorten the treatment time and improve the hemodynamics of infants .
4.The research progress of PD-1 channel inhibition in tumor treatment
Tianjin Medical Journal 2015;(9):1085-1095
Programmed death1 (PD-1) is mainly expressed on the surface of activated T cell. The combination between PD-1 and its legends PD-L1/PD-L2 activate downstream signaling pathways and negatively regulate T cell activation. Ab?normal increase expression of PD-L1 on tumor cell surface mediates the tumor immune escape. Inhibition of PD-1 signaling pathway contributes to antitumor effect of T cells. The development of this pathway inhibitors has become a hot spot for tu?mor immunotherapy. This article expounds the progress about antitumor effects mediated by PD-1 pathway inhibition from experiments in vivo or in vitro and clinical development of PD-1 pathway inhibitors, providing a new target for cancer immu?notherapy and theoretical and clinical basis for the clinical application of immunotherapy with traditional therapy methods.

The resection can be performed in about 20 percent of patients with primary hepatocellular carcinoma(PHC) in clinic. However, with the development of interventional treatment such as transcatheter arterial chemoembolization(TACE), better therapeutic effect has been achieved by two-stage resection such as TACE in patients with unresectable PHC. At present, surgical resection is still regarded as the first choice of PHC, and the principle of comprehensive therapeutic solutions around surgical operation has been established. The pretreatment of TACE is an important measure to improve the therapeutic effect in PHC.This paper discussed the mechanism, effect and value of TACE in pretreatment of unresectable PHC. The selection of operative opportunity, sign, and ways after TACE and the factors affecting prognosis of two-stage resection were also reviewed.

Objective To investigate the application of colposcope in cervical cancer screening in Yunnan ethnic minority areas.Methods The questionnaire survey was conducted on 641 women,and the data of the colposcopy and biopsy were reviewed retrospectively.The colposcopy and pathological diagnosis results were compared.Results The minority women thought colposcopy more acceptable was 78.64% (383/487).The colposcopy found suspected low-grade cervical lesions were 377 cases,high-grade cervical lesions were 245 cases,cervical condyloma were 15 cases,cervical cancer were 4 cases.The pathological results:278 cases of cervical intraepithelial neoplasia (CIN) Ⅰ,174 cases of CIN Ⅱ,55 cases of CIN Ⅲ,15 cases of cervical condyloma,4 cases of cervical cancer.The consistent rate of colposcopy and pathological examination was 68.17% (257/377) in low-grade lesions,89.39% (219/245) in high-grade lesions,cervical cancer and cervical condyloma was entirely consistent.Conclusions The colposcopy is more easily accepted in Yunnan ethnic minority areas,which could be a preliminary diagnosis of cervical lesions,cervical condyloma and cervical cancer.It has an important clinical application value in diagnosis of cervical diseases.

This is the first report on gene therapy of mice melanoma by HSV - tk/ACV system. The sensitivity to ACV of genetically modified B16 cells (B16LNTK) was much higher than that of the parental cells. The sensitivity to ACV of B16 cells was increased when they were co - cultured with B16LNTK cells with various ratios. which showed the exist of the by stander effects. The tumor volume of B16LNTK (0.25cm3) is 94% less than that of B16 in C57BL/6 mice after 20-days ACV treatment. (P

Aim To study the effect of two racemic ketamine, S(+)-ketamine and R(-)-ketamine on stimulus-induced superoxide generation and intracellular calcium in vitro. Methods The stimulus-induced superoxide generation in human neutrophils was determined by using method of cytochrome C reduction. The intracellular calcium in human neutrophils was measured by chemiluminescence with Fura-2 loading. The phosphorylation of p47phox of NADPH oxidase in neutrophils was detected by Western blotting. Results S(+)-Ket and R(-)-Ket inhibited fMLP-induced superoxide generation in neutrophils in a concentration-dependent manner. In the case of PMA, S(+)-Ket inhibited PMA-induced superoxide generation and elevation of intracellular calcium of neutrophils in a concentration-dependent manner, whereas R(-)-Ket slightly increased PMA-induced superoxide generation and elevation of intracellular calcium of neutrophils. On the other hand S(+)-Ket inhibited the phosphorytion of p47phox of NADPH oxidase subunit,which R(-)-Ket was increased. EGTA can abolished the inhibition of S(+)-Ket on PMA-induced phosphorytion of p47phox.Conclusion S(+)-Ket inhibits the phosphorylation of p47phox of NADPH oxidase subunit and the superoxide generation in human neutrophils via PKC-calcium signal pathway.
