A novel approach of vaccination against cancer is to exploit dendritic cells (DC) as the best antigen presenting cells (APC) and actively immunize cancer patients with a sample of autologous or allogeneic DC primed with tumor antigens. DC vaccination is still at its early stage, however, valuable proofs of concept have been obtained with respect to the capacity of DC to expand cancer directed immune responses. The methods for preparing DC are being improved continuously, and there are many opportunities to improve efficacy at the level of DC biology. An increased number of clinical studies will drive the development of this new area. This paper reviews the production of dendritic cell tumor vaccines and their use in clinical trials, as well as emphasizes some unresolved questions in this immunotherapy.

Objective To investigate the protective effects of ischemic preconditioning on myocardial ischemia/reperfusion injury in diabetic rats.Methods Twenty-eight healthy male rats were injected streptozotocin at dose of 45 mg/kg by tail and be fed with normal diet for 4 weeks,then rats were randomly divided into iscbemia/reperfusion (I/R) group and ischemic preconditioning (IP) group.ST segment of electrocardiograph changes and arrhythmias of all rats were recorded before ischemia and 0,15,30 minuets after ischemia and 0.5,2 h after reperfusion.TTC staining was performed to determine myocardial infarct size.TUNEL assay was used to assesse cardiomyocyte apoptosis.The expression of antiapoptotic gene (Bcl-2) and proapoptotic (Bax) was determined by immunohistochemistry.Results Compared with I/R group,ST segment elevation of patients in IP group decrease from (0.675 ±0.150) mV to (0.489 ±0.161) mV at 30 min after ischemia(P ＜0.05).Meanwhile the onset of ventricular premature contraction(VPC) in IP group was (18.21 ± 5.36) min,later than that of control group ((6.47 ± 4.28) min,t =5.241,P =0.000).The duration of VPC was (6.07 ± 4.33) min,shorter than that of I/R group ((16.71 ± 5.48) min,t =4.924,P ＜ 0.01)).The incidence of ventricular tachycardia (VT) and ventricular fibrillation (VF) of lP group remarkably decreased compared with I/R group (VT:57.14％ (8/14) vs.14.29％ (2/14),x2 =5.600,P =0.018 ; VF:50.00％ (7/ 14) vs.14.29％ (2/14),x2 =4.094,P=0.043).The myocardial infarct size in IP group was (12.50 ± 9.45) ％,smaller than that of I/R group ((37.50 ± 11.40)％,t =3.211,P =0.006).Cardiomyocyte apoptotic index (AI) was attenuated in IP group than that of I/R group((24.31 ± 3.12)％ vs.(19.01 ± 4.32)％,t =3.227,P =0.006),which was correlate with increased the ratio of Bcl-2/Bax((0.103 ±0.045) vs.(0.221 ±0.101),t =2.670,P =0.015).Conclusion IP treatment for diabetic rats shows a protect effect on myocardial I/R injury through attenuating myocardial apoptosis,and increasing the ratio of Bcl-2/Bax.

Objective To investigate the clinical features,therapeutic methods,therapeutic effect and prognosis of a case of bladder urothelial carcinoma patients in combination with trophoblast.Methods The pathological data of a patient with bladder high grade urinary epithelial carcinoma in combination with trophoblast was retrospectively analyzed and the related literatures were reviewed.It was a male patient,69 years old,presenting with total painless gross hematuria.The CT scan showed irregular nodules on the anterior wall of bladder.Results Cystoscopy showed 1.5 cm cauliflower mass on the anterior wall of bladder,and transurethral resection of bladder tumor was performed.The pathology and immunohistochemistry showed urothelial carcinoma.Lung metastases was found due to hemoptysis,and increased serum beta human chorionic gonadotropin (β-HCG) was detected simuhaneously.Pathology was double checked and bladder urothelial carcinoma with trophoblast cell differentiation was considered.Three cycles gemcitabine + cisplatin (GC regimen) and 2 cycles etoposide + methotrexate + vincristine + cyclophosphamide (modified EMA-CO regimen) therapies were given,and the disease was stable at that time.The patient died on June 10,2016,and the total survival period was 9 months.Conclusions The clinical and imaging of urothelial carcinoma with trophoblast differentiation is not special.Diagnosis must depend on the pathological and immunohistochemistry examinations.The efficacy can be evaluated by combining imaging with serumβ-HCG.Treatment should be systemic venous chemotherapy.

Purpose:We evaluated the sensitivity and specificity of p53 antibodies (p53-Ab) as a preoperative tumor marker and as a prognosis marker in colorectal cancer patients and we also investigated whether p53-Ab production is dependent on p53 protein overexpression in tumor tissue.Methods:Serum samples from 178 colorectal cancer patients and 40 healthy controls were tested for the presence of p53-Ab by using an ELISA kit. Expression of p53 protein in tumors was determined using mouse anti-human p53-Ab.Results:Serum p53-Ab was detected in 18.54% of patients while all controls were negative. A strong correlation between p53-Ab production and p53 protein expression was observed: 69.7%of p53-Ab positive cases had tumors positive for p53 vs 30.3%of p53-Ab negative cases. There was also a significant predominance of p53-Ab positive cases in Dukes ’ stages B (16/71,22.54%), C (12/55,21.82%)and D(5/30,16.67%)over stage A. No difference in patients’ age, sex and localization was found between the p53-Ab positive and negative groups. Recurrence of cancer did not differ between p53-Ab positive and negative patients after a median follow-up of 13.5 months and also median survival time did not vary significantly.Conclusions:There was a significant correlation between p53-Ab production in serum and p53 protein expression in tumor tissue. Because of their low sensitivity (18.54%) p53-Ab are not suitable as a preoperative tumor marker. However, their high specificity (100%) and their potential for early diagnosis of a tumor relapse makes them valuable for postoperative monitoring during follow-up in p53- Ab positive patients.[
