M2 type of pyruvate kinase (PKM2) is one of the most important regulatory molecules in glycolysis,which at high level is a major feature of tumor cells.Besides,PKM2 also regulates gene transcription and cell cycle,promoting the formation,invasion and migration of tumors.Meanwhile,PKM2 can beregulated by many transcription factors,oncogene proteins,miRNA and intermediate metabolites.Extensive studies indicated that PKM2 plays an important role in the developmental tumor.In view of the significance of PKM2 in tumor cells,it holds promise for diagnosis and treatment benefits.

OBJECTIVETo study the clinicopathological characteristics of papillary cystadenoma of the epididymis.
METHODSUsing routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature.
RESULTSThe 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases.
CONCLUSIONPapillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

Objective To investigate effects of dendritic cells (DC) vaccine on immune function in postoperative gastric cancer patients Methods DCs were extracted and pulsed with self tumor antigens in vitro Fifty patients with gastric cancer were divided into 2 groups randomly Four times of DC vaccinations were administered at 7 days intervals to the postoperative patients in treatment group after they underwent chemotherapy The control group were treated with chemotherapy only The level of IL 12 、 IFN ? and IL 4 in peripheral blood were analysed Results In DCs group, the levels of IL 12 were 37?4、 68?6、 96?12 and 59?9 pg/ml, the levels of IFN ? were 61?12、 134?19、 145?20 and 111?15 pg/ml, and levels of IL 4 were 55?7、 49?6、 46?5 and 50?8 pg/ml before and 2, 4 and 8 weeks after vaccination, respectively In control group, the levels of IL 12 were 39?7、 45?9、 44?10 and 44?6 pg/ml, the levels of IFN ? were 63?10、 61?13、 62?11、 61?7 pg/ml, and levels of IL 4 were 52?11、 55?9、 53?10、 55?8 pg/ml before and 2, 4 and 8 weeks after vaccination, respectively The levels of IL 12 and IFN ? increased significantly in DCs group No severe side effects were found during treatment Conclusion DC vaccine improves immune function of posroprative patients with gastric cancer

Qi-Gui-Yin (QGY) compound, which composes of five herbal medicines of Astragalus membranaceus (Fisch.) Bge., Angelica sinensis (Oliv.) Diels, Lonicera japonica Thunb., Artemisia annua L., and Polygonum cuspidatum Sieb.et Zucc., which is able to treat antibiotic-resistant bacteria with antibiotics, and also to delay or even reverse the bacterial resistance producing. However, QGY compound is a complex mixture. And it is very difficult to elaborate its material foundation. Therefore, chemical constituents in five herbal medicines were summarized through searching of the related literatures. And then, 170 kinds of bioactive ingredients were classi-fied in order to provide evidences for the study on chemical constituent of QGY compound and identify its mate-rial foundation of delaying drug resistance .

This study examined the effect of different b values on diffusion-weighted MR imaging (DWI) of human prostate by using single-shot spin echo echo planar imaging (SE-EPI) sequences, observed the normal appearances and measured apparent diffusion coefficient (ADC) values in anatomical regions of normal prostate. Twenty-four healthy volunteers (mean age: 32 y) were studied by using a 1.5T system with a phased array surface multicoil. Two kinds of single-shot SE-EPI sequence were used to perform DWI in the prostate in volunteers, with five b values being 0, 30, 300, 500 to 1000 s/mm(2). The image quality with different imaging parameters was analyzed and the ADC values in anatomical regions of normal prostate were measured. DWI of prostate was successfully obtained in all volunteers. The images were of good quality, without artifacts containing pixels within the prostate. The contrast was good between the different anatomical regions of the prostatic gland, i.e., the peripheral zone (PZ), which exhibited higher signal intensity, and the central gland (CG). Signal intensity contrast was related to the magnitude of b values. The ADC values in PZ and CG were (1.27+/-0.22)x10(-3) mm(2)/s and (1.01+/-0.17)x10(-3) mm(2)/s, respectively. The ADC values were found to be significantly higher in PZ than in CG (P<0.05, paired t-test). Significant differences were found between the slice-selecting component and both the read-out and phase-encoding components of the ADC values. It is concluded that SE-EPI is a suitable DWI sequence for human prostate. The contrast between PZ and CG is good when b values are low, while the diffusion and ADC values are accurate when b values are high. ADC values are higher in PZ than in CG in normal prostate. Diffusional anisotropy is present in normal prostatic tissue.
