Objective To investigate the expression and clinicopathological features of gene associated with retinoid-interferon mortality-19 (GRIM-19) in epithelial ovarian carcinoma.Methods The expression of GRIM-19 gene in tissues from 138 cases of epithelial ovarian carcinoma,102 cases of benign ovarian epithelial tumor and 46 cases of normal ovarian tissues were detected by Immunohistochemistry and Western blot methods.Assembled clinical survival data were analyzed with Kaplan-Meier and Cox regression models.Results The expression level of GRIM-19 in epithelial ovarian carcinoma (3.4 ± 2.0) was lower than that in benign ovarian tumor tissues (4.7 ± 2.9) and that in normal ovarian tissues (7.5 ± 2.2 ; P ＜0.01).The level of GRIM-19 expression was related to the survival time of epithelial ovarian carcinoma patients by Kaplan-Meier analysis (P =0.002).The shorter survival time of epithelial ovarian carcinoma patients was significantly associated with the level of GRIM-19 expression (P =0.001),clinical stage (P =0.001),volume of ascites (P =0.023) and the largest diameter of the primary tumor lesion (P =0.044) by Cox regression models.Conclusions The low expression of GRIM-19 in the epithelial ovarian carcinoma suggests that GRIM-19 may be a key gene involved in its carcinogenesis.The expression level of GRIM-19 may be also an independent prognostic factor for epithelial ovarian carcinoma patients.

Objective To evaluate the efficacy of percutaneous CT guided interstitial 125Ⅰ seeds implantation treatment for refractory pelvic malignant tumors and discuss the procedure of technique.Methods Twenty-three patients with refractory pelvic malignant tumors(25 lesions,diameter 3.5-7.0 cm,mean 4.5 cm) showing failure response to full chemotherapy and/or radical radiotherapy after tumors resection were undergone percutaneous CT guided intratumoral 125Ⅰseed implantation.Treatment plan system(TPS)was used to design the distribution and number of 125Ⅰ seeds according to matched peripheral dose(MPD)1-3 days before the procedure.Of which 6 cases received combined internal iliac arterial infusion chemotherapy before or after the 125Ⅰ seed implantation procedure.Results 9 ～ 75(mean 27)125Ⅰ seeds were implanted into a single tumor at first time including 6 patients with intraarterial chemotherapy for 14 cycles(mean 2.3 cycles),showed relief of clinical pain symptoms in 16 of 23 cases,72 h ～ 4 w after the seeds implantation;with the an effective rate of 69.6%.Follow up for 2-34 months(median,21 months),CT or MRI performed 2 months after the seeds implantation showed no CR,but PR in 18 cases,SD in 4 cases,and PD in 1 case,with overall response rate of 78%(18/23),and no serious complication.In addition,20 cases survived,with the longest one of 34 months and the other 3 died.Conclusions Intratumoral 125Ⅰ seeds implantation under CT guidance for pelvic refractory malignant tumors is safe,minimally invasive,and effective.

BACKGROUND:Islet and islet cel transplantation for the treatment of diabetes has achieved effect, but the research is limited dut to the shortage of islet and immune rejection. OBJECTIVE:To observe the effect of transplantation of islet-like cells that in vitro differentiated from bone marrow mesenchymal stem cells on the treatment of diabetes in rats. METHODS:The rat bone marrow mesenchymal stem cells were induced with basic fibroblast growth factors and hepatocyte growth factors, and then received immunocytochemistry staining to detect the induction. The Sprague Dawley rats received intraperitoneal injection of streptozotocin to establish the diabetes models. After modeling, the rats were randomly divided into control group and experimental group (transplanted with induced islet-like cells). The experimental group was transplanted with the induced islet-like cells through renal capsule, and the control group was transplanted with normal saline in the same dose. The blood glucose and body mass of the diabetes rats were observed after transplantation. RESULTS AND CONCLUSION:The bone marrow mesenchymal stem cells could differentiate into islet-like cells after in vitro induced with basic fibroblast growth factors and hepatocyte growth factors. There was no significant change in blood glucose of the control group after transplantation (P>0.05), and the blood glucose of the rats in the experimental group was significantly decreased compared with the control group (P<0.05). The bone marrow mesenchymal stem cells can differentiate into islet-like cells after in vitro induced with the induction system containing basic fibroblast growth factors and hepatocyte growth factors, and the islet-like cells have a certain ability of insulin secretion. The transplantation of induced islet-like cells after transplanted into the diabetes rats through renal capsule can decrease the blood glucose level of the rats.

Objective To evaluate the relationship between the perfusion mode of neovascularization of carotid plaque in CEUS and the ischemic stroke in transient ischemic attack (TIA) patient.Methods A total of 73 TIA patients according to the inclusive criteria were enrolled.All the patients underwent routine carotid ultrasonic examination.And 61 patients with plaque thicker than 2.5 mm in carotid bifurcation underwent CEUS and follow-up for at least 18 months.All the patients were divided into recurrent and non-recurrent groups.Logistic regression analysis were performed to detect the risk factors for incurrence of ischemic stroke or recurrence of TIA in 18 months.Results There were statistical differences between 2 groups in hypertension,diabetes,hyperlipemia,smoking history,family history of stroke,medication compliance,two-dimensional ultrasound and CEUS characteristics (all P＜0.05).Multivariate Logistic regression analysis showed that all the factors correlated with the recurrency,from big to small order were the CEUS characteristics of carotid plaque,hypertension,medication compliance,diabetes,two-dimensional ultrasound characteristics of carotid plaque.Conclusion CEUS could evaluate the perfusion mode of neovascularization in carotid plaques.For TIA patients,CEUS could predict the incurrence of ischemic stroke or recurrence of TIA,which can guide TIA patients targeted prophylaxis of them.

Objective To evaluate the safety and clinical efficacy of stereotactic body radiation therapy (SBRT) for lung cancer.Methods A retrospective analysis was performed on 200 patients with primary non-small cell lung cancer (NSCLC)(118 patients) or solitary pulmonary metastasis (82 patients) who underwent SBRT in Zhejiang Cancer Hospital from January 2012 to September 2015.The 80% isodose line covered 95% of the planning target volume,and the 100% isodose line covered 100% of the internal gross tumor volume.The fractional dose was 4.0-18.0 Gy daily or every other day,and the biologically equivalent dose ranged from 40.0 to 151.2 Gy (median 100 Gy).Results All patients completed treatment.The follow-up rate was 96.0%.The complete response and partial response rates were 14.8%(17/115) and 65.2%(75/115) for the primary tumor group,versus 25%(19/77) and 38%(29/77) for the metastasis group.The incidence rates of grade Ⅱ and Ⅲ acute radiation pneumonitis were 4.7% and 3.1%,respectively.The median follow-up was 14.9 months.The 1-and 2-year local control rates were 95.7% and 84.3% for the primary tumor group,versus 92% and 73% for the metastasis group.The 1-and 2-year overall survival rates were 94.5% and 92.0% for the primary tumor group,versus 85% and 62% for the metastasis group.Conclusions SBRT is a safe and effective treatment for early primary NSCLC and solitary pulmonary metastasis,resulting in high 1-and 2-year local control and overall survival rates and low rate of complications.

OBJECTIVETo observe the effect of puerarin on infarction size, fatty acids metabolism, inflammatory response and atherosclerotic plaque stability in patients with acute myocardial infarction (AMI).

METHODSSixty-one patients with AMI were randomly divided into two groups, the control group (n = 30) and the treated group (n = 31). All were treated with conventional treatment, but to the treated group, puerarin injection was given additionally by injecting 500 mg per day for 2 weeks. Before and after treatment, blood levels of free fatty acids (FFA), matrix metalloproteinases-9 (MMP-9) and C-reactive protein (CRP) were assayed, and the size of infarction was determined by Ideker QRS scoring method.

RESULTSBefore treatment, the size of infarction was positively correlated to the levels of FFA, MMP-9 and CRP (r = 0.43, 0.42 and 0.39, respectively, all P<0.01). As compared with those before treatment, after treatment, the three parameters lowered by 30%, 41% and 23%, respectively and the size of infarction significantly reduced in the treated group (P<0.01), while in the control group, no significant change was found (P>0.05).

CONCLUSIONPuerarin treatment could significantly reduce the size of infarction in patients with AMI, the mechanism is possibly related with its effects in lowering plasma levels of FFA, inhibiting inflammation and stabilizing atherosclerotic plaque.
