500 thousands people died from gastric cancer in China over 2015,shortage of clinical medicines and therapeutic methods is one of the reasons for the high mortality.Tumor immunotherapy is the hottest area of research over the past decade,whose success in hematological malignancies makes people raised their confidence to “cure” cancer.In recent years,gastric cancer immunotherapy research has made some achievements,while clinical outcomes still need improvement.In this paper, the progress of clinical research of common immunotherapeutic drugs and methods in several fields of gastric cancer research are reviewed to discuss the development prospects of immunotherapy for gastric cancer .

As a member of PARP superfamily, PARP3 shares a high homology with PARP1 and PARP2, which are all DNA-dependent enzymes that are catalytically activated by DNA strand breaks.Compared to PARP1 and PARP2, PARP3 exerted some special properties in tissue expression pattern and biological function.The evidence has shown that PARP3 could be activated by DNA double strand breaks and special DNA single strand breaks and synthesize mono(ADP-ribose) (MAR) covalently attached to target proteins including itself.PARP3 plays an important role in DNA double strand breaks, DNA single strand breaks, activation of PARP1 and development of nervous system.It has been reported that PARP3 is associated with glioma and breast cancers.In this review, PARP3 structure, activation mechanism, biological function and its relationship with diseases will be presented.

E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

Objective To establish a malignant pleural effusion model of Lewis lung cancer in C57BL/6 mice based on Micro Echo technology. Methods Single tumor cell suspension of Lewis lung cancer was injected into thoracic cavity.The pleural effusion was detected by Micro Echo technology.The volumes of effusion were quantified and the tumor cells were counted.Results After implanted of tumor cell, malignant pleural effusion can be detected by Micro Echo technology and observed after autopsy.Chemotherapy drugs such as Cyclophosphamide and Cisplatin can decrease the effusion volumes.Conclusion Pleural effusion model of Lewis lung cancer based on Micro Echo technology can be used to evaluate the efficacy of antitumor drugs.

To clone the differential genes in antibiotic resistence Neisseria gonorrhoeae,the library that contains the fragments of differential genes between antibiotic resistance strain and standard reference strain of Neisseria gonorrhoeae was constructed which used suppression subtractive hybridization technique. Then the antibiotic resistance relational genes fragments were cloned and analyzed. Antibiotic resistance Neisseria gonorrhoeae subtractive library that has high subtractive efficiency was set up successfully. The amplified library contained 2500 positive clones. Sequence analysis was performed to find the fragments of antibiotic resistance relational genes. Five sequences were unknown previously. The fragments of antibiotic resistance genes may provide an important clue for studying the mechanism of occurrence and development of antibiotic resistance Neisseria gonorrhoeae.

Objective To investigate the correlation between executive function(EF) and characteristic of symptom in children with Tourette′s syndrome(TS).Methods EF were measured with Wisconsin Card Sorting Test(WCST) in 53 patients with TS,and symptom characteristics were evaluated with Achenbach Child Behavior Checklist(CBCL) and Yale Global Tic Severity Scale(YGTSS).Results Compared with healthy control,TS had poor executive performances significantly in WCST(all P
