1.Research progress on PD-1/PD-L1 inhibitors in prostate cancer immunotherapy
Chinese Journal of Clinical Oncology 2017;44(16):831-834
The annual incidence of prostate cancer (PCa) continually increases. New PCa immune therapy has become the fourth line antitumor treatment following surgery, radiotherapy and chemotherapy. As the most promising research direction in cancer immunotherapy,immune checkpoint inhibitors, such as programmed cell death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) inhibitors, block PD-1 and its ligand PD-L1 and then terminate the negative control signal to the T cell, thereby facilitating T cell recovery and reversal of tumor immune-escaping mechanism. These processes restore the capability of T cells for immune response and inhibit and kill tumor cells. This review summarizes the progress on the current application of PD-1/PD-L1 inhibitors in PCa clinical trials.
2.THYROGLOBULIN ANTIBODY PRODUCTION BY CULTURED PERIPHERAL BLOOD MONONUCLEAR CELLS FROM PATIENTS WITH AUTOIMMUNE THYROID DISEASE
Chinese Journal of Endocrinology and Metabolism 1985;0(02):-
Thyroglobulin antibody (TGA) production in vitro by cultured peripheral blood mononuclear cells (PBMC) from patients with autoimmune thyroid disease (AITD) was measured by ELISA technique. PBMC from patients with AITD could synthesize and secret detectable amount of TGA. The average positive rate of TGA production in vitro was 31.25%. PBMC from the patients with Hashimoto thyroiditis (HT) could produce TGA more easily than that from the patients with Graves'disease (GD). The average positive rate was 44.19% in HT and 16.22% in GD. Pokeweed mitogen could increase TGA production, but soluable thyroglobulin could not stimulate TGA synthesis and secretion. Antithyroid drug methi-mazole had some inhibition effect on TGA production in vitro. A significant positive correlation between the serum TGA and the amount of TGA produced in vitro by PBMC from HT patients (r = 0.4, P
3.THE EFFECT OF CHRONIC LITHIUM. ON CALMODULIN ACTIVITY IN RAT BRAIN
Journal of Chongqing Medical University 1986;0(04):-
Lithium(Li) salt is. a kind of effective drug commonly used in the treatment and prevention of mental disorders, but its active mechanism is still not well understood. Getting on for twenty years, many research have been reported on relationship between Li salt and second messenger system, especially the effect of Li salt on adenylate cyclase. Identical result is not obtained and there are few reports on brain calmodulin (CaM) activity change by Li salt. The aim of present expcri- ment is to determine the content of CaM in raet brain by phosphodiesterase (PED) method after chronic application of Li salt and discuss preliminary the molecular mechanism of Li salt action. The result showed that marked change has happened in the content of CaM in rat brain after chronic application of Li salt. It is ins-plied that Li salt brings its action into play probably by changing the content of CaM in rat brain
6.Mutual promotion, mutual assistance and mutual inhibition in the compatibility of acupoints.
Chinese Acupuncture & Moxibustion 2015;35(10):1021-1024
Mutual promotion, mutual assistance and mutual inhibition are commonly for the compatibility of Chinese herbs, but they are also existed among the acupoints. In the paper, the relevant literature on acupoint, compatibility was collected and the mutual promotion, mutual assistance and mutual inhibition relationships of acupoints were described. The laws of the above mentioned combinations, the theoretic evidences and modern researches were summarized briefly. The mutual promotion and mutual assistance refer to the coordination of acupoints, presenting the relationship of the primary and the secondary about the mutual assistance. Hereby, the acupoints could be divided into the simple assistant acupoints and the acupoints from the affected meridians. The mutual inhibition is used to describe the antagonism effect in acupoint combination. There are more researches on the mutual promotion of acupoint combination but less ones on the mutual inhibition and its mechanism is just hypothetic. It is very important to have the deep study on those compatibility relationships for the improvement of acupuncture efficacy and to elaborate the effect mechanism.

8.Analyses of the Mycorrhizal Research State and Development in China Based on SCI Database
Microbiology 1992;0(03):-
Papers on mycorrhizas were searched from SCI (Science Citation Index) database. In order to understand the research progress of mycorrhizas in China, the paper on mycorrhizas from 1989 to 2007 was analyzed with method of bibliometrics. Mycorrhizal researches showed an increasing tendency during 1989 to 2007, while the increase was obviously accelerated after 2000. Only 5.22% of the articles were published in journals with impact factor above 5, indicates that the academic levels of researches need being enhanced. Currently the research on mycorrhizas was mainly focused on Arbuscular mycorrhiza (AM), especially on effects of mycorrhizal fungi on plant physiology, effects of mycorrhizal fungi on resistance of host plants, Mycorrhizal diversity community and ecological distribution, and phytoremediation with Mycorrhizal plants. The future research should emphasize in phytoremediation with Mycorrhizal plants and identification of fungal species with molecular biological technology.

Using hybridoma technique,17 hybridoma cell lines against astrocyte were ob-tained.The screening test of McAb showed:(1)Using immune enzymatic histochemistryfixed cell staining method all of 17 McAb reacted with astrocyte,(2) Using immuneenzymatic histochemistry viable cell staining method,eight of seventeen McAb react-ed with astrocyte.As to biological properties of McAb results were as follows:(1)Seven of eight McAb that showed positive reaction in viable staining assay have di-fferent degree of cytotoxicity to astrocyte,thymocyte and spleen cell in presence ofcomplement,one of eight has specific cytotoxicity only to astrocyte.(2) McAb(2C)possesses blocking effect on astrocyte,thymocyte and spleen cell proliferation respon-sive to various kind of mitogen.Furthmore,it has been found LPS may promote theproliferation of astrocytes and secreting interleukin 1(IL-1)-like substance This IL-1like substance seems to have a mutiple biological activities,i.e:(1)Thymocyte prolife-ration.(2) Fibroblast(L929 cell) proliferation and(3) Endogenous pyrogen activities.
10.To screen for SQSTM1/p62 gene in Chinese patients with familial amyotrophic lateral sclerosis carrying superoxide dismutase 1 mutation
Chinese Journal of Internal Medicine 2014;53(12):957-960
Objective To explore the clinical features and SQSTM1/p62 gene mutations in Chinese Han patients with familial amyotrophic lateral sclerosis linked superoxide dismutase 1 (SOD1) mutation (FALS-SOD1).Methods A total of 13 FALS-SOD1 probands and 100 healthy controls were studied,with DNA extracted from the peripheral blood.Sequencing was carried out at 8 exons,intron-exon boundaries and promoter region (2-kb upstream from the coding sequence) of SQSM1/p62.Clinical data were collected and all patients were followed-up.Phenotype-genotype relationship was analyzed.Results The insertion of T was found in intron 5 of SQSTM1/p62 gene [+ 1 insert T (TT > TG)] in a FALS-SOD1 G16A male proband,with limbs as the symptom onset and faster disease progression than the other two SOD1 G16A probands without SQSTM1/p62 gene mutation.Conclusions The insertion of T in the intron 5 of SQSTM1/ p62 gene may promote the ALS progression by damaging p62 function in the FALS-SOD1 G16A proband.
