Journal of Xi'an Jiaotong University(Medical Sciences) 1982;0(01):-
Acute lymphoblastic leukemia has been divided into four immunological types with anti-pan-T, anti-CALLA, anti-HLA monoclonal antibo-dies and Es rosctte forming test and SmIg surface analysis. The results of immunolgical typing of 19 ALL cases reveal that the majority of those cases is C-ALL type and the B-ALL type appears rarely, the majority of T-ALL appears in boys.
2.Inhibition of Pulmonary Surfactant Function by Endotoxic Rat Plasma and Its Mechanisms
Academic Journal of Second Military Medical University 1982;0(02):-
The inhibition of bronchoalveolar surfactant function by endotoxic rat plasma was compared with that by normal rat plasma with M-8601 film balance. The results showed that endotoxic rat plasma significantly inhibited surfactant function of bronchoalveolar lavage (BAL). In the same protein concentration, the inhibition effects caused by endotoxic rat plasma were comparable with those by normal rat plasma. There were no changes of the inhibition effects after incubation of BAL with either endotoxic or normal plasma at 37℃ for 30min. These results suggest that the inhibition of surfactant function by the leakage of plasma in endotoxic lung injury is mainly due to protein components.

Journal of International Oncology 2014;(7):495-499
Recentyearshavewitnessedmuchprogressinbothbasicresearchandclinicaltrialsregar-ding cancer immunotherapy with chimeric antigen receptor (CAR)-engineered T cells.CAR combine the varia-ble regions of a specific monoclonal antibody (scFv)with the CD3ζendodomain.The extracellular domain of CAR-engineered T cells directly dock to the tumor-associated antigen (TAA).When T cells bind to target anti-gens,they mediated redirected cytotoxicity and secrete a series of cytokines such as Perforin,Granzyme,Inter-feron-γ(IFN-γ)and Tumor necrosis factor-α(TNF-α),which would eventually lead to the necrosis of tumor cells.Although the antitumor response of the CAR-engineered T cells is considered as successful and surpri-sing,it should be noted that some safety issues have been observed in other several basic researches and clinical trials.This overview focuses upon the utility and safety of the CAR-engineered T cells.

Journal of Medical Postgraduates 2016;29(10):1063-1066
Objective Recently a lot of studies have shown carbon nanoparticles can protect parathyroid, however, there is no application in outpatient thyroid operation. The article was to investigate the influence of carbon nanoparticles suspension ( CNS) in?jection on the operation and prognosis of outpatient thyroid microcarcinoma(TMC) surgery. Methods Retrospective analysis was conducted on the clinical data of 65 patients who underwent outpatient TMC surgery from January to June in 2015 in our hospital. The patients were divided into 2 groups:33 patients in trial group were injected with CNS, and the other 32 patients in control group under?went conventional surgery. Comparison was made in operation information, pathologic data, postoperative complications, postoperative hospital stay as well as C?reactive protein(CRP) and blood calcium of the first day after operation between the two groups. Results The average number of VI region lymph nodes in trial group(8.21±2.08)was significantly higher than that of control group(P=0.004). Removal of 5 parathyroid glands for mistake was detected in control group, but no removal of parathyroid gland was detected in trial group, showing significant difference (P=0.028). 3 patients in control group had numbness in skin, while none in trial group. The hospital stay of trial group was lowered significantly in comparison to that of control group([31.09±6.62] vs [35.75±7.37], P=0.009). The average C?reactive protein ( CRP ) of the first day after operation in trial group was much lower that of control group([7.17±5.20] vs [9.87±5.60] mg/L, P=0.048). The average blood calcium of the first day in trial group was much higher than that of control group ([2.07±0.17] vs [1.98±0.20] mmol/L, P=0.036). Conclusion Outpatient TMC surgery injected with carbon nanoparticles sus?pension can protect parathyroid gland function, reduce surgical stress and accelerate recovery.
5.The effect of p70S6K1 and 4EBP1 protein in colorectal cancer
Journal of International Oncology 2015;(5):392-394
The phosphatidylinositide-3-kinase(PI3K)/ protein kinase B(Akt)/ mammalian target of rapamycin(mTOR)pathway is recognized to have an important role in the development and progression of colo-rectal cancer(CRC). The most extensively characterized downstream targets of mTORC1 are ribosomal protein S6 kinase 1(p70S6K1)and eukaryotic translation initiation factor(eIF)4E-binding protein 1(4EBP1),both of which are crucial to the regulation of protein synthesis. The abnormal expression of p70S6K1 and 4EBP1 in CRC has become the focus of attention.

BACKGROUND:The inflammation of osteoarthritis is mediated by chondrocytes and the synovial tissue-secreted cytokines. Articular cartilage and synovial tissue contains a variety of cytokines, which play important regulatory role in the repair of articular cartilage injury.
OBJECTIVE:To analyze the relationship between chondrocytes, synovial tissue-secreted cytokines and osteoarthritis, as wel as the effect of chondrocytes and synovial tissue-secreted cytokines on osteoarthritis.
METHODS:A computer-based search was conducted in Wanfang database (www.wanfangdata.com.cn), PubMed database (www.ncbi.nlm.nih.guv/pubmed) by the first author from 2005 to 2010. The key words were“osteoarthritis, degeneration, cartilage tissue, cytokines”. A total of 146 articles were obtained through computer search, then reading the titles and abstracts for initial screen, 86 articles with the unrelated research purposes were eliminated, 40 articles with the repetitive content were excluded, and final y 21 articles related to the effect of various cytokines in the degenerative cartilage and synovial tissue of the osteoarthritis patients were included for further analysis.
RESULTS AND CONCLUSION:The cytokines mainly refers to the activated immune cel s and some stromal cel-secreted non-specific regulate immune responses and inflammatory responses-mediated smal molecule proteins, including lymphokines produced by the lymphocytes, as wel as the single nuclear factor and other cytokines produced by monocytes macrophages. Synovial cel-secreted cytokines may partial y explain the pathological process of osteoarthritis and play an important role in joint inflammation. Although, more and more scholars have pay attention to the effect of synovial cel s and cartilage cel-secreted cytokines, but mainly studies the effect of exogenous cytokines on chondrocytes or synovial cel s, and the effect of endogenous cytokines in the pathogenesis of osteoarthritis has not been extensively studied.
