Objective To observe the changes of T lymphocyte subsets and natural killer (NK) cells in patients with late stage non-small cell lung cancer (NSCLC) before and after treatment with PD-1 inhibitor and its clinical effect.Methods Totally 23 patients with NSCLC in Guangzhou Modern Hospital from January 2015 to January 2016 were collected.All patients were given 6 cycles of PD-1 inhibitor treatment after chemotherapy or targeted drug treatment failure.Peripheral venous blood was collected before and after treatment to detect the percentage of CD3 +,CD4 +,CD8 + and NK cells in peripheral blood lymphocytes.The curative effects were evaluated by chest CT after treatment of 2,4,6 cycles.Results Compared with before treatment,the proportions of CD3+ (69.56％ ±7.81％ vs.63.91％ ±6.43％,t =2.679,P =0.005),CD4+ (39.01％ ±4.98％ vs.36.09％ ±4.77％,t =2.031,P =0.024) and CD4+/CD8+ (1.82 ±0.48 vs.1.49 ± 0.32,t =2.743,P =0.004) were increased after treatment,with significant differences.While compared with before treatment,the proportions of CD8 + (24.08％ ± 5.13％ vs.26.04％ ± 6.44％,t =1.142,P =0.130) and NK cells (22.68 ％ ± 9.56％ vs.21.45 ％ ± 10.01％,t =0.426,P =0.337) had little changes,with no significant differences.There were 3 patients with complete remission,10 patients with partial remission,8 patients with stable disease and 2 patients with progressive disease when completing 6 cycles of PD-1 inhibitor treatment.Ten patients showed untoward effects such as mild sleepiness,thirst,tussis,pruritus and rash,and they were well tolerable.Conclusion PD-1 inhibitor can improve the patient's cellular immune function,and can achieve a more satisfactory short-term efficacy and acceptable adverse reactions,which maybe bring new hopes for patients with NSCLC.

Objective To investigate correlation between the amount of interleukin-17 (IL-17) producing cells and the expression of transforming growth factor (31 (TGF-β1) in glioma,and evaluate the clinical values of IL-17 and TGF-pl in predicting the prognosis of glioma. Methods The presence of IL-17 and TGF-pl was measured by immunohistochemistry in 135 human glioma (WHO Ⅰ 18,WHO Ⅱ 45,WHO Ⅲ 53,WHO Ⅳ 19) tissues and 15 normal brain tissues. Results There was no IL-17 positive staining in normal brain tissues. Of 135 glioma specimens showed low TGF-pl expression and 77 (57. 03% ) showed high TGF-pl expression. No TGF-β1 expression was detected in normal brain tissue. Furthermore,TGF-β1 expression was positively correlated with the amount of IL-17 producing cells in glioma tissues ( r=0.285, P<0.01). Compared with the low grade,the levels of IL-17 and TGF-pl positive cells were obviously increased in high grade. The Kaplan-Meier analysis showed that there were significant differences in overall survival (OS) between the IL-17 and TGF-pl high-expression and lowexpression group (P＜0.01, P＜0.05). The 3-year OS rates of IL-17 of high expression and low expression were 33.75% and 76. 36%. Multivariate Cox proportional hazards regression analysis indicated that age,KPS score, IL-17 were independent prognostic factor for OS (P＜0.01). Conclusion Intratumoral IL-17-producing cell density and the expression of TGF-β1 was associated with the malignancy of human glioma.

To explore the discrimination model of subhealth with statistical method of partial least squares (PLS).

We reported a simple and fast fluorescence system based on quantum dots ( QDs ) to detect glutamate dehydrogenase ( GLDH) , which inverted glutamate to α-ketogrutarate using NAD+ as a coenzyme. The fluorescence of CdTe QDs was quenched by nicotinamide adenine dimucleotide ( NAD+) through an electron transfer pathway, and the quencher NAD+ could be consumed by adding NAD+-dependent enzymes and corresponding substrates. Based on this principle we introduced GLDH to consume NAD+ in the QDs/NAD+ system, leading to the enhancement of the fluorescence intensity of QDs, which was in proportional to the amounts of GLDH added. Using this fluorescence system, we measured GLDH in a wide concentration range from 10 U/L to 1000 U/L, which was of significance in clinical diagnosis of different kinds of liver diseases.
