Tianjin Medical Journal 2014;(12):1243-1245
Interleukin (IL)-35 is a new member of IL-12 family who is secreted by T regulatory cells to strongly sup?press immuno reaction directly or indirectly. There is a growing interest in the using IL-35 as a potential therapy for chronic in?flammatory , cancer and autoimmune diseases. Here we reviewed IL-35 and its function as a mediator of suppression.

Thyroid carcinoma is the most common malignancy in the endocrine system.Most patients cannot be cured with operation alone.The concept and implementation of multidisciplinary team (MDT) in clinical oncology attributes to improved diagnosis and treatment of cancer.MDT plays an important role in diagnosis,treatment,and post operational management of thyroid carcinoma,as well as in the application of novel techniques and translational medicine.MDT can maximize the expertise of various disciplines,strengthen inter disciplinary cooperation,and provide standardized and individualized comprehensive treatment for patients with thyroid cancer.The most important benefit of MDT is that individual patient gets the most appropriate treatment decision made by a team of experts,including endocrinologists,nuclear medicine specialists,pathologists,radiologists,radiation therapists,and surgeons.This will be of great significance to improve quality of life and prognosis,at the same time,avoid over-treatment of thyroid cancer.

Objective To summarize the therapeutic experience on malignancy patients complicated with hyperthyroidism.Methods Clinical date of 10 cases of surgical malignancy complicated with hyperthyroidism admitted from May 2004 to May 2010 in Tianjin Medical University General Hospital were analyzed retrospectively.Results Four cases were treated by subtotal thyroidectomy before radical operation for cancer.Radical operation for cancer was performed on 6 patients after clinical symptoms of hyperthyroidism were controlled by perioperative antithyroid agents.Postoperatively 3 patients complicated with clinical manifestations similar to thyroid crisis.There was no postoperative mortality.Chemotherapy was given to 10 patients,and 1 patient was discontinued for chemotherapy caused leucopenia.Conclusions Hyperthyroidism should be controlled by surgery or antithyroid agents before patients of malignant diseases could proceed with radical surgery.Proper preoperative medication and effective postoperative management can reduce operation risk and help the patients get through the perioperative period safely.

Objective To investigate the effect of Foxp3 gene expression induced with the DNA methyltransferase inhibitor 5-aza-2'-deoxycytidine (Aza) in recipients on ameliorating allograft rejection and prolonging allograft survival and the possible mechanisms.Method BALB/c and C57BL/6 splenocytes treated with mitomycin (MMC) served as the stimulators,those not treated with MMC as responders,and they were subjected to one-way mixed lymphocyte culture (MLC).In the presence or absence of Aza,the percentage of CD4+ CD25+ Tregs was detected by flow cytometry.Abdominal heterotopic heart transplantation model was established by using inbred male Balb/c mice as donors and C57BL/6 as recipients respectively.In experimental group,recipients were intravenously administrated with decitabine (1.5 mg/kg/day) on the day 1 to day 3 post-transplantation.The control mice were treated with normal saline.CD4+ CD25+ Tregs proportion in the blood and Foxp3 mRNA in cardiac grafts and spleen of recipients were measured respectively,and the survival and the histopathologic changes of the cardiac grafts were also observed.Result Decitabine enhanced the proliferation CD4 + CD25 + Tregs of MLC in vitro.The median survival time of the cardiac grafts in experimental group (11 days) was longer than that in control group (7 days) (P<0.01).As compared with control group,Foxp3 mRNA expression in the cardiac grafts and spleen in recipient mice was significantly up-regulated,and CD4+ CD25 + Tregs proportion was increased (P<0.01) and the proliferation of lymphocytes and monocytes infiltration was inhibited.Conclusion Up-regulation of Foxp3 gene expression induced with decitabine in recipients could alleviate cardiac allograft rejection and prolong cardiac allograft survival via the induction of proliferation and differentiation of CD4+ CD25 + Foxp3 + Tregs.

Objective To investigate the adjunctive therapeutic effects and safety of intravenous immunoglobin (IVIG) for treating pneumonia following kidney transplantation.Methods Sixteen cases of pulmonary infection after kidney transplantation were divided into two groups.Twenty-eight cases were subjected to IVIG therapy (0.2 g·kg-1 ·day-1) for 7-10 days besides the standard specific anti-bacterial,anti-fungal,and anti-virus treatment and regular immunosuppressive regimen with dose adjustment (IVIG group),and the control group was only treated with standard specific anti-pathogen therapy.The incidence and mortality ofsevere pulmonary infection,levels of serum IgG,T lymphocyte subsets,and creatinine in the two groups were observed.Results The effective power of IVIG group and control group was 100 % and 93.75 % (P<0.05).The incidence of severe pneumonia in IVIG and control groups was 0 and 12.5%,respectively (P<0.05),with the mortality being 0 and 6.25%,respectively (P< 0.05).The levels of serum IgG were significantly increased in IVIG group as compared with that before treatment and in control group.There were no significant adverse reactions associated with IVIG infusion.Conclusion As an adjunctive therapy,IVIG treatment for pulmonary infection can reduce the incidence of severe pulmonary infection and mortality after kidney transplantation,further increase the survival rate of patients after kidney transplantation.

Objective To explore the correlations between expression of miRNA-21 and PTEN and the invasion, metastasis of colorectal carcinoma.Methods The mRNA level of miRNA-21 and mRNA and protein levels of PTEN were assayed by real-time quantitative PCR and immunohistochemical methods respectively in 65 colorectal carcinoma specimen.Results The expression of miRNA-21 mRNA in cancer tissues was significantly higher than that in paracancerous tissues (t =3.50, P < 0.05).Both mRNA and protein expressions of PTEN in tumor tissue were significantly lower than that in paracancerous tissues (t =7.35,t =12.23;P < 0.05).Expression of miRNA-21 mRNA, PTEN mRNA and protein were obviously related with depth of invasion(F =18.36 ,F =17.26 ,F =12.83;P < 0.05), Dukes stage (F =31.25, F =24.43, F =57.12;P < 0.05) and lymph node metastasis (t =5.85, t =2.18, t =4.05;P < 0.05), while it was not related to tumor differenciation and tumor location (F =7.39, t =4.62;F =7.78, t =1.29;F =5.14,t =1.37;P > 0.05).Positive relation between miRNA-21 and PTEN in colorectal carcinoma was identified (r =-0.994, r =-0.927;P < 0.05).Conclusion High expression of miRNA-21 and low expression of PTEN are both closely associated with invasion and metastasis of colorectal carcinoma.

Objective: To retrospectively characterize and analyze the thyroid ultrasound images of thyroid cancer patients, to classify thyroid nodules according to thyroid imaging reporting and data system (TI-RADS), and to evaluate the diagnostic value of TI-RADS. Methods:Clinical data of 160 thyroid cancer patients with 235 nodules from September 2008 to August 2011 were retro-spectively analyzed. All patients underwent conventional color Doppler ultrasonography to evaluate the size, number, shape, boundary, and extent of lesions and blood distribution of the nodules. All nodules were analyzed according to TI-RADS classification and scored to evaluate the diagnostic value of TI-RADS. Results:Among 176 malignant nodules, 144 (81.8%) had lesions showing a mass of irreg-ular boundary with no envelope and halo, 152 (86.4%) were inhomogeneous hypoechoic or slightly hypoechoic, or 144 (81.8%) exhibit-ed microcalcification. TI-RADS scores of 4 or 5 and 2 or 3 were obtained in 160 (90.91%) and 16 (9.09%) of the malignant nodules, re-spectively. Conclusion:Thyroid ultrasound sonogram of ill-defined, irregular shape, hypoechoic or slightly hypoechoic mass, microcal-cification within the mass, and rich blood flow is an important index for the diagnosis of thyroid cancer. Thyroid nodules with a TI-RADS score 4 or 5 have higher possibility for cancer. Therefore, TI-RADS has a significant diagnostic value for thyroid cancer be-fore operation.
