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
2.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.

Aim A method of coculture of brain capillary endothelial cells (BCECs) and astrocytes of rats was used to evaluate nanoparticle' s blood-brain barrier (BBB) transcytosis and toxicity at the endothelial tight junction. Methods A lipophilic fluorescent probe, 6-coumarin, was incorporated in poly(ethyleneglycol)-poly (lactide) nanoparticle using double emulsion/solvent evaporation method. BCECs and astrocytes were firstly isolated from brain of newborn rats and characterized by their morphology and immunocytochemistry staining, separately. Subsequently, a coculture model with BCECs on the top of micro-porous membrane of cell culture insert and astrocytes on the bottom side was established. The permeability of 14C-labeled sucrose and nanoparticle were determined, separately. Results The meanweight-based diameter of 6-coumarin loaded nanoparticles was ( 102.4 ± 6.8) nm, with zeta potential of ( - 16.81 ± 1.05) mV. BCECs were positive for factor Ⅷ staining and glial fibrillary acidic protein was tight junction between BCECs in the coculture model could be visualized by both scanning electron microscopy and transmission electron microscopy. The unchanged paracellular transport of sucrose proved vivo situation for examination of the permeability of nanoparticle and toxicity evaluation.

Background and purpose: ~(125)I seeds implantation was mainly used in the treatment of prostate cancer. Recently, this technique has been used to treat other solid tumors such as lung cancer or liver cancer. The objective of this study was to evaluate the technique and effect of interstitial brachytherapy for intraperitoneal tumors. Methods: From February 2006 to January 2009, 20 patients with intraperitoneal tumors were treated with interstitial brachytherapy. The study included 7 cases with liver metastases, 8 cases with retroperitoneal lymph nodes metastases, three cases with pancreatic cancer, 2 cases with pelvic recurrence of rectal cancer. Results: All the patients received CT scan follow up 2 months after treatment. CR, PR, SD, PD were obtained in 7, 7, 3 and 3 cases, respectively. The total response rate was 70%. Conclusion: Interstitial brachtherapy is one of the effective treatments for the patients with intraperitoneal tumor. The adverse events are tolerable but the long-term benefits of this treatment method need further study.

Objective To discuss the clinical curative effects of Kaihoujian spray in the treatment of acute suppurative tonsillitis in children. Methods 120 cases of pediatric patients with acute suppurative tonsillitis were selected and randomly divided into the observation group and the control group (60 cases in each group); the control group were given conventional western medicine treatment, while the observation group received Kaihoujian spray on the basis of the control group treatment; clinical symptoms and curative effects of the two groups were evaluated and compared. Results In the observation group, sore throat and fever disappearance time, purulent secretion, tonsil swelling disappearance time and hemogram recovery time were all significantly shorter than those in the control group (P<0.05); after 3 courses of treatment, in the two groups, children temperature, sore throat, tonsil fester and tonsil swollen main symptom scores were all significantly decreased (P<0.05), but the observation group decreased more obviously (all P<0.05). After treatment, C-reactive protein, white blood cell count, neutrophils of the two groups all significantly reduced (P < 0.05), but the observation group decreased more obviously (all P<0.05). Conclusion Using Kaihoujian spray to treat acute suppurative tonsillitis could significantly improve the clinical symptoms and signs, whose clinical curative effect is good, and has no adverse reactions.

Piggyback orthotopic liver transplantation was performed in three patients with terminal liver disease.After resection of the patient′s liver with preservation of the recipient inferior vena cava,the donor liver was transplanted into the patient with an end to end anastomosis of the inferior vena cava above the liver,portal vein,hepatic artery and common bile duct between the donor and the recipient liver,with the ligation of subhepatic inferior vena cava.The liver rejection was controlled by FK506,Xiaoxi and prednisone. We reinforced monitoring of the patient and infection was prevented after the operation.So far,two patients have survived and led a normal life for 12 and 9 months,respectively.The third patient died of renal failure on the postoperative 14 days.The liver transplantation is a safe and effective curative means for terminal liver disease.
