0.05). Nine HLA-A2-restricted CTL epitopes of CT10 were found. Conclusion CT10 mRNA is expressed with a high percentage and specificity in hepatocellular carcinomas. The CT10 gene product is potential target for antigen-specific immunotherapy of hepatocellular carcinoma.

Objective To explore the possibility of immune therapy for hepatocellular carcinoma (HCC) with MAGE-3 antigen peptide (FLWGPRALV). Methods The expression of HLA-A2 in HCC patients were examined with microcytotoxicity assay .The mRNA of MAGE-3 genes in the tumor tissues were detected by RT-PCR, the CD8 positive T lympocytes were separated as effector cells with immunobeads from peripheral blood mononuclear cells (PBMCs) of those patients. The irradiated autologous CD8 negative PBMC were pulsed with MAGE-3 peptide as APC. Some effector cells were co-cultured with APC, and some not as the control. After 14 days′ culture with IL-2, the frequency of effector cells secreting IFN-? in response to MAGE-3 peptide were monitored by IFN-? secretion assay. The hepatocellular carcinoma cell line HLE was used as the target cells.ResultsNine HCC patients were HLA-A2 positive in 25 HCC patients, and 3 of them were MAGE-3 mRNA positive. After two weeks′ culture, the effector cells increased by 4-6 folds. The frequency of CD8 positive cells secreting IFN-? in response to MAGE-3 peptide was 22.0% in 3 MAGE-3 mRNA positive patients(n=3),and 0.5% in 6 negative patients( n=6) (?

Objective To investigate the postoperative changes of serum proteins and immune responses in critical patients and the effect of recombinant human growth hormone(rhGH).Method 45 critical patients were divided randomly into rhGH group (15 cases) and control group (30 cases) after operation. Patients in rhGH group were given rhGH 8*!U/d,im for 7 days starting 48 hours post operation. Result The postoperative level of serum transferin,albumin and prealbumin decreased in all patients, and so did the activity of CD 3,CD 4 ,CD 8,NK and the ratio of CD 4/CD 8 .Serum prealbumin level increased significantly in rhGH group at day 4 and after ( P

BACKGROUND: Pioglitazone is a common hypoglycemic drug capable of improving proliferation and activation, and inhibiting apoptosis of endothelial progenitor cells (EPCs). We speculated that the combined use of pioglitazone and EPCs transplantation could have significant improving effects on hyperglycemia and kidney function after diabetes mellitus.OBJECTIVE: To investigate the improving effect of EPCs transplantation combined with pioglitazone treatment on the kidney function of diabetic rat models.METHODS: The 15 of 75 Wistar rats were randomly selected and served as normal control group (no treatment). Animal models of type 1 diabetes mellitus were made in the rest 60 rats through the intraperitoneal injection of 40 mg/kg streptozotocin for continuous 5 days. The human EPCs (labeled by CM-Dil) were recovered, cultured and preserved until transplantation. After 4 weeks of modeling, the 60 rat models were randomly divided into model group (PBS injection), pioglitazone group, EPCs transplantation group and combined treatment group, followed by tail vein injection of EPCs suspension and/or intragastric administration of 20 mg/kg pioglitazone for continuous 4 days. After 8 weeks of treatment, the levels of glucose, insulin and creatinine in serum, urea nitrogen and urine protein during 24 hours were determined. The number and distribution of EPCs labeled by CM-Dil were detected by fluorescence microscope, the apoptosis in kidney cells was tested by TUNEL method, and the kidney weight/body weight ratio in rats was calculated.RESULTS AND CONCLUSION: Compared with the model group, the blood glucose and serum creatinine levels and the urea nitrogen and urine protein concentrations during 24 hours were significantly decreased (P < 0.05), and the seruminsulin level was significantly increased (P < 0.05) in the pioglitazone and EPCs transplantation groups. These biochemical indexes in the combined treatment group were more significantly altered compared with the model group (P< 0.01). The kidney weight to the body weight ratio was lowest in the combined treatment group and lower in the pioglitazone and EPCs transplantation groups followed by the model group (P < 0.05). The order of apoptotic kidney cells labeled by TUNEL was as follows: model group > pioglitazone group > EPCs transplantation group > combined treatment group (P < 0.05). To conclude, the EPCs transplantation combined with pioglitazone treatment can decrease the blood glucose and serum creatinine levels and urea nitrogen and urine protein concentrations, improve the serum insulin level, reduce cell apoptosis in the kidney, and remit the kidney dysfunction of diabetic rats to a certain extent.

Objective To evaluate the diagnostic procedures and treatment choice of primary malignant tumor of the duodenum.Methods The clinical data of 170 cases with primary malignant tumor of the duodenum at Peking University People's Hospital from 1996 to 2015 were analyzed retrospectively.Results Tumors located in the first,second,third and fourth parts in 14 cases (8.2％),144 cases (84.7％),9 cases (5.3％),and 3 cases (1.8％) respectively,and among them,tumors within papillary area accounted for 62.4％ (106 cases).The main clinical presentations included jaundice,upper abdominal pain,abdominal distention,nausea and vomiting.Among the 170 cases,125 cases obtained accurate tumor stages,with 34 cases on stage Ⅰ (27.2％),45 cases on stage Ⅱ (36.0％),30 cases on stage Ⅲ (24.0％),16 cases on stage Ⅳ (12.8％).The accuracy rate of ultrasound and CT in preoperative diagnosis was 27.6％,and 72.3％ respectively.The pathological type of 144 cases (84.7％) was adenocarcinoma.The postoperative 1-,3-and 5-year survival rate was 69.1％,48.6％ and 33.9％.Conclusions Most primary malignant duodenal tumors are located in papillary region,necessitating radical pancreaticoduodenecomy,early diagnosis remains the key for longterm survival.
