After allogeneic hematopoietic stem cell transplantation (allo-HSCT), the donor cells present a profound immunization therapy efficiency. Among these effector cells, allo-reactivity natural killer (NK) cell activation are concerned with the graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect. As known, GVHD is primarily a T-cell-mediated event but not initiated by NK cells. NK cells may significantly enhance GVL immune response by using an integration of activating and inhibitory receptors. Allo-reactivity NK cell infusion after allo-HSCT already transits from experiments to clinic. In this review the background on NK cells, and their clinical roles in Allo-HSCT were summarized.

OBJECTIVETo observe the inhibitory effect of gefitineb on the proliferation and its inducing effect on the apoptosis of mouse I-10 Leydig testicular cancer cells in vitro.

METHODSWe treated I-10 Leydig testicular cancer cells of mice with gefitineb at 0, 1.25, 2.5, 5, 10, 20, and 40 µmol/L. Then we determined the inhibitory effect of gefitineb on the growth of the cells by MTT, detected their early and late apoptosis by Annexin V-FITC/propidium iodide double staining and Hoechst 33258 nuclear staining, respectively, and observed the expressions of apoptosis-related proteins Bcl-2, Bax and caspase 3/9 by Western blot.

RESULTSCompared with the blank control group, gefitineb significantly inhibited the proliferation of the I-10 cells at 10 and 20 µmol/L (P < 0.05). The survival rate of the cells was (32.4 ± 2.8)% (P < 0.01) and their early and late apoptosis rates were (26.7 ± 4.2)% and (59.33 ± 10.2)% in the 40 µmol/L group, significantly different from those in the control (P < 0.05 and P <0.01). In comparison with the blank control group, gefitineb at 10, 20, and 40 µmol/L increased the expression of pro-apoptotic protein Bax by (41.9 ± 7.1), (60.1 ± 9.8), and (69.0 ± 11.3)% (all P < 0.05), decreased that of apoptosis-inhibitory protein Bcl-2 by (50.3 ± 8.9), (63.9 ± 6.9), and (88.7 ± 13.9)% (all P < 0.05), and elevated that of the cleft proteins caspase-3 by (69.0 ± 6.9)% (P < 0.05), (71.5 ± 8.1)% (P < 0.05), and (110.9 ± 14.2)% (P < 0.01) and caspase-9 by (51.8 ± 4.9), (54.7 ± 6.7), and (43.8 ± 11.8)% (all P < 0.05).

CONCLUSIONGefitineb can increase the cytotoxicity of I-10 Leydig testicular cancer cells of mice and induce their apoptosis via the mitochondria-mediated apoptosis signaling pathway.

Objective To investigate the relationship between carotid arteriostenosis and atheromatous plaques with cerebral in-farction.Methods Cervical spiral CT angiography of 56 cases with cerebral infarction and 49 cases without cerebral infarction were retrospectively analysed .The difference between the two groups was compared with regard to the distribution ,nature of plaques and the degree of carotid artery stenosis.Results Of 56 patients with cerebral infarction,126 atheromatous plaques were detected in 42 patients,of which 39 were soft,34 were calcified,53 exhibited a combined nature of both calcified and soft plaque and 7 cases were plaque ulcerations (soft plaque and mixed plaque accounted for about 73%).Plaque location for carotid artery was in the bifurcation. 102 carotid arteries stenosis were found in 38 patients,which included mild stenosis in 29,moderate in 40,severe in 27 and occlusion in 6(moderate and severe stenosis accounted for about 65.7%).In the control group,28 plaques were detected in 1 1 cases,of which 6 were soft,13 were calcified and 9 exhibited a combined nature of both calcified and soft plaque.1 1 carotid arteries stenosis were found in 7 patients,included mild stenosis in 10,moderate in 1.A significant difference (P <0.05)in carotid arteriostenosis and ath-eromatous plaques between the two groups was found.Conclusion Carotid plaques and stenosis are important risk factors of cerebral infarction.Multi-slice spiral CT angiography(MSCTA)has important value in analysis of carotid artery stenosis and atheroderotic plaques.

The technique of double-layered plate was developed for screening the library of mutant endoglucanase III from Trichoderma reesei generated by the method of directed evolution.The enzyme activity was determined according to the velocity of the formation of halos on the plates.Several mutants with higher activity than the wild type at low temperature or alkaline pH were obtained by using this strategy under different screening conditions.Further results of spectrophotometric determination of the activities of these mutants were consistent with the results of plate screening.The establishment of such strategy will broaden the applications of the directed evolution methods for improving the existing proteins to obtain useful enzymes with new properties for industrial applications.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

Background Monocyte chemoattractant protein-1 (MCP-1) polymorphisms are demonstrated to be significantly associated with the susceptibility to uveitis in recent years,while a consistent conclusion for the association of MCP-1-2518A/G polymorphism and uveitis risk is not reached yet.Objective This study was to comprehensively investigate the correlation between MCP-1-2518A/G polymorphism and uveitis susceptibility.Methods General searches of electronic database including PubMed,Embase,Web of Science,CNKI,VIP,Wanfang database and China biomedical literature database (CBD) were performed to retrieve published case-control studies regarding the association between MCP-1-2518A/G polymorphism and uveitis risk.The data were screened according to the inclusion and exclusion criteria and extracted,and the quality of included studies was evaluated.The pooled odds ratios (OR) with 95％ confidence intervals (CI) were calculated.Publication bias and sensitivity analysis were also assessed.All statistical analyses were conducted with RevMan 5.2 and Stata 12.0 software.Results A total of 8 eligible case-control studies involving 1 197 cases and 1 570 controls were included in the Meta-analysis.The results showed no significant association of MCP-1-2518A/G polymorphism with uveitis susceptibility in the G vs.A,GG vs.AA and GG vs.AG+AA models (all at P＞0.05).MCP-1-2518A/G polymorphism was found to be significantly associated with uveitis risk in the GG+AG vs.AA model (P =0.01,OR =1.25,95％ CI:1.06-1.48),while no significant association was found by the sensitive analysis (GG + AG vs.AA:P =0.19,OR =1.16,95％ CI:0.93-1.45).The subgroup analysis by uveitis types revealed that the individuals carrying allele-G or GG genotype harbored a significantly increased risk for anterior uveitis (G vs.A:P=0.01,OR=1.49,95％ CI:1.16-1.90;GG vs.AA:P=0.01,OR=2.09,95％ CI:1.21-3.61;GG+AG vs.AA:P=0.01,OR=1.58,95％ CI:1.12-2.23;GG vs.AG+AA:P=0.01,OR=1.78,95％ CI:1.12-2.83).The individuals with GG+AG vs.AA genotype harbored a significantly increased risk for Behcet's disease (BD) (P=0.04,OR =1.35,95％ CI:1.01-1.79) but not for other types of uveitis (P ＞ 0.05).Additionally,a significantly elevated risk was found in uveitis patients with allele-G or GG genotype in Asian population in the subgroup analysis based on ethnicity (G vs.A:P =0.04,OR =1.15,95％ CI:1.01-1.32;GG vs.AA:P=0.04,OR=1.32,95％ CI:1.02-1.71;GG+AG vs.AA:P=0.01,OR =1.36,95％ CI:1.09-1.70),but that was not found in Caucasians population (all at P＞0.05).Conclusions MCP-1-2518A/G polymorphism is significantly associated with the risk of uveitis in Asian population,anterior uveitis and BD.The allele-G or GG genotype may increase the risk of uveitis in Asian population,anterior uveitis and BD.

AIM: To compare the safety and efficacy of conjunctival autograft transplant ( CAT ) and limbal - conjunctival autograft transplant (LCAT) for primary pterygium.
METHODS: In this prospective, randomized and controlled clinical study, 120 patients ( 120 eyes ) diagnosed with primary pterygium were collected in NO. 474 Hospital of Chinese PLA from January 2014 to January 2015. The 120 patients enrolled in the study in turn, and divided into two group by the odd and even number. The odd number underwent CAT and the even number underwent LCAT.
RESULTS:One hundred and seven patients (107 eyes) completed the follow-up of 1a, including 54 patients (54 eyes) from the CAT group and 53 patients (53 eyes) from the LCAT group. Four patients (4 eyes, recurrence rate 7. 4%) in the CAT group and 2 patients ( 2 eyes, recurrence rate 3. 8%) in the LCAT group developed recurrence. However, there were no significant in recurrence rate between CAT group and LCAT group (P =0. 678).
CONCLUSION: CAT and LCAT might be both effective treatment for primary pterygium for reducing the recurrence rate of pterygium. However, LCAT is the optimal surgical method for primary pterygium.
