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 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.

6.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.
7.The progression of chimeric antigen receptor modified T cells in malignant tumor
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.

Objective To investigate 1762T、1764A double position mutation in the Basic Core Promoter(BCP) of hepatitis B virus and reveal its relation to clinical symptoms and HBeAg phenotype. Methods microplate sandwich hybridization technique was used to detect BCP double position mutation. One common capture probe and one mutant specific detector probe as well as one wild type detector probe were synthesized and hybridized with amplified HBV DNA from the sera of hepatitis B patients. The results of hybridization were exhibited with ELISA. Results 147 hepatitis B patients who had been confirmed HBV DNA positive were screened. 51 patients were BCP double position mutation, 42 of which were BCP single position mutation and, 9 were mix mutation(both mutation and wild type were positive). BCP mutant was detected in 36 of 117 with chronic hepatitis and, 8 of which were mix mutants. Moreover, BCP mutant was detected in 7 of 30 with acute hepatitis in 25 of 78 with HBeAg positive were mutant and in 26 of 65 with HBeAg negative were mutant.Conclusions (1) The rate of BCP double position mutation in chronic hepatitis B patients is higher than that in acute hepatitis B patients. (2) BCP mutation may impair HBeAg expression. (3) PCR microplate sandwich hybridization ELISA is a sensitive and efficient method for detecting gene mutations.
