ATP (Adenosine triphosphate) is an important endogenous damage-associated molecular pattern (DAMP). P2X7R is an ATP-gated cation channel. ATP-P2X7R plays a vital role in the pathophysiology of many diseases because P2X7R is distributed on various immune cells. ATP-P2X7R signal transduction pathway has been implicated to participate in the body's im-mune defense against pathogens. This paper reviews the recent progress regarding ATP-P2X7R and its effects on parasitic diseas-es.

To investigate the therapeutic effect of peroxiredoxin-6(PRDX6)on ultraviolet-induced corneal injury in rats and explore the mechanism.The rat model of corneal injury was established by exposing to ultravio-let.Male wister rats were randomly divided into control groups,dexamethasone (DXM)groups and PRDX6 groups,the rats were administered four times a day and for 12 days.The corneal opacity was observed with a slit-lamp microscope.Histopathologic changes were observed with light microscopy.The content of corneal malonalde-hyde(MDA)was determined by thiobarbituric acid test and the total antioxidative capacity(TAOC)was detected by chemical colorimetric test.P38 MAPK signal pathway was detected with the method of Western blot and the gene expression of cytokines were measured by RT-PCR method.Compared with the control group,PRDX6 treat-ment significantly reduced corneal opacity,improved corneal pathology injury,decreased the MDA content and in-creased the TAOC.In the PRDX6 group the level of phosphorylated p38 protein was significantly lower than that in the control group.The gene expression of cytokine were different between control and PRDX6 groups(P <0.05).PRDX6 showed therapeutic effect in the rat model of ultraviolet-induced corneal injury.This maybe be concerned with that it could alleviated the oxidative damage,suppressed p38 MAPK phosphorylation and regulate the gene expression of cytokine.

Objective To investigate the effectiveness and safety of anterior vitrectomy combined with capsular retractor and Cionni modified capsular tension ring (MCTR) in traumatic lens subluxation surgery with anterior vitreous prolapse.Methods This study comprised 16 patients (16 eyes) of traumatic lens subluxation with anterior vitreous prolapse,in which iridodialysis was in 3 eyes,express implantation in 1 eye and Ahmed glaucoma valve implantation in 1 eye.According to the severity of lens subluxation,the patients were divided into three levels,including 90°-120° (7 eyes),120°-180° (5 eyes) and 180°-270° (4 eyes).Considering the anterior vitreous prolapse,anterior vitrectomy or/and pars plan vitrectomy was conducted with assistance of triamcinolone acetonide.After continuous curvilinear capsulorhexis,two to four capsular retractors were placed in the capsulorhexis to support and center the capsule.MCTR was inserted with scleral suture fixation after phacoemulsification.At last,the foldable IOL was implanted to capsular bag.Postoperative visual acuity,intra-and post-operative complications,anterior capsular opening,IOL positions and intraocular pressure (IOP) were assessed during 3 months' follow up.Results All patients had successfully undergone phacoemulsification,MCTR insertion and IOL implantation.Seven eyes were inserted with 2-eyelet MCTR and nine eyes were inserted with 1-eyelet MCTR.The postoperative visual acuity was better than 0.5 in 9 eyes,between 0.3 and 0.5 in 4 eyes,between 0.1 and 0.3 in 2 eyes,and less than 0.1 in 1 eye.Compared with pre-operation,the difference in the visual acuity was statistically significant (x2 =17.503,P =0.000).The scheimpflug images obtained from the Pentacam,which demonstrated that the IOL was well centered,and no MCTR and IOL decentration occurred.The common intraand post-operative complications were residual cortex,aqueous misdirection syndrome,anterior capsular tears,anterior capsular phimosis and posterior capsular opacification.Conclusion The effective application of anterior vitrectomy is the key point to reduce surgical complications.Anterior vitrectomy combined with insertion of capsular retractor and MCTR is an ideal surgical option for patients of traumatic lens subluxation with anterior vitreous prolapse.

Objective To explore the effect and mechanism of CD4+CD25+Tregs(Tregs)on the protective efficacy of glutha?tione?S?transferase(GST)against Schistosoma japonicum in mice. Methods Female BALB/c mice were divided randomly into five groups:a normal control group,an infected control group,an anti?CD25mAb group,a GST immunization group and a com?bination group with GST immunization and anti?CD25 mAb. The GST group and combination group were injected percutaneously with GST 50μg each mouse,the other two groups were injected with equal volume PBS. The immunization was performed for 3 times for two?week interval,and 2 weeks after the last immunization,each mouse was challenged with 40 S. japonicum cercaria. Two weeks post?infection,the combination group and anti?CD25 mAb group were injected intraperitoneally with 300μg anti?CD25 mAb each mouse. The mice were succumbed 2 weeks,3 weeks,4 weeks and 5 weeks post?infection respectively. The per?centages of CD4+CD25+Tregs in splenocytes of mice were measured with flow cytometer. The levels of IFN?γ,IL?2,IL?4,IL?5 and TGF?βin cell cultural supernatants were determined by sandwich?ELISA after stimulation with Con A. The liver sections were stained with hematoxylin and eosin. Results The worm burden in the combination group(15.80 ± 2.74)was significantly lower than those of the infected control group(27.78 ± 3.15),anti?CD25 mAb group(21.50 ± 4.21),and GST group(20.84 ± 6.46). Compared to those of the infected control group,the percentages of CD4+CD25+Tregs were significantly higher in the GST group,while the percentages of CD4+CD25+Tregs were significantly lower post?anti?CD25 mAb?administration. Regardless of GST administration,the levels of IFN?γ,IL?2,IL?4 and IL?5 after anti?CD25 mAb were significantly higher than those of the in?fected control groups. There were no significant differences of egg granuloma and the level of TGF?βbetween each group. Con?clusion CD4+CD25+Tregs could be partially blocked by anti?CD25 mAb while Th1 and Th2 type immunization response could be enhanced,which plays a role in improving the protective efficacy of GST against of S. japonicum.

It has been widely verified by various sorting methods that cancer stem cells (CSCs) exist in different types of tumor cells or tissues. However, due to lack of specific stem cell surface markers, CSCs are very difficult to be separated from some cancer cells, which becomes the key barrier of functional studies of CSCs. The sorting method by side population cells (SP) lays a solid foundation for in-depth and comprehensive study of CSCs. To identify the existence of SP in prostate cancer cell lines, we applied flow cytometry sorting by SP to cultures of prostate cancer cell lines (TSU, LnCap, and PC-3), and the cancer stem-like characteristics of SP were verified through experiments in vitro and in vivo. The proportion of SP in TSU cells was calculated to be 1.60%±0.40% [Formula: see text], and that in PC-3 and LnCap cells was calculated to be 0.80%±0.05% and 0.60%±0.20%, respectively. The colony formation assay demonstrated that the colony formation rate of SP to non-SP sorted from TSU via flow cytometry was 0.495±0.038 to 0.177±0.029 in 500 cells, 0.505±0.026 to 0.169±0.024 in 250 cells, and 0.088±0.016 to 0.043±0.012 in 125 cells respectively. In the in vivo experiments, tumors were observed in all the mice on the 10th day after injecting 50 000 cells subcutaneously in SP group, whereas when 5×10(6) cells were injected in non-SP group, tumors were developed in only 4 out of 8 mice until the 3rd week before the end of the experiment. Our results revealed that prostate cancer cells contain a small subset of cells, called SP, possessing much greater capacity of colony formation and tumorigenic potential than non-SP. These suggest that SP in prostate cancer cells may play a key role in the self-renewal and proliferation, and have the characteristics of cancer stem-like cells. Dissecting these features will provide a new understanding of the function of prostate CSCs in tumorigenicity and transformation.

Objective To evaluate the effects of blood-lipid report's reformat on outpatients' behavior and knowledge of dyslipidemia therapy.Methods The blood-lipid report was reformatted by adding three tables from the Chinese Guideline on the Prevention and Treatment of Adult Dyslipidemia on its back.The same questionnaire was used twice to evaluate the patients' behavior and knowledge of dyslipidemia therapy before and after reformat.Results Before and after reformat,the rates of correct deterination of their own risk stratification were 26.0％ ( 112/430 ) and 26.3％ ( 115/438 ) respectively.The awareness rates of Different LDL-C goals among different persons wcre 37.0％ (159/430) and 35.8％ (157/438).Only 0.7％ (2/306) and 1.0％ (3/299) of patients knew their blood lipid goals (P =0.557).When the report showed normal blood lipid levels,the percentages of taking lipid-lowering drug were 47.6％ ( 230/483 ) and 46.6％ ( 216/464 ),20.5％ ( 99/483 ) and 19.0％ ( 88/464 ) of patients questioned the prescription.Non-medication rates were 31.9％ ( 154/483 ) and 34.5％ ( 160/464 ) respectively before and after reformat ( P ＞ 0.05 ).For patients requiting lipid-lowering drug therapy by the guideline,treatment rate improved significantly in the low-risk group (13.3％ vs.75.0％,P =0.002).Treatment rate slightly increased in the high-risk and very high-risk groups after reformat (54.0％ vs.56.8％,62.4％ vs.69.0％,P ＞ 0.05 ).Rates of achieving lipid goal showed no change [ 41.5％ ( 102/ 245 ) vs.44.5％ ( 114/256 ),P ＞ 0.05 ] after reformat,especially among the very high-risk patients [17.9％(12/68) vs.21.6％(11/52),P＞0.05].Conclusions The blood-lipid report reformat did not improve the patient behaviors and knowledge of the prevention and treatment of dyslipidemia because of poor treatment rate and medication compliance.The combination of patient education and thorough blood-lipid report reformat may help to increase the attainment rate of dyslipidemia therapy.

Objective: To explore the forces of lower limbs during side slip and forward slip through biomechanical study, and to provide a theoretical basis for the development of lower limb movements. Methods: BTS SMART DX motion capture analysis system, 8 infrared high-speed cameras, Kistler three-dimensional dynamometer, BTS FREEEMG 1000 portable wireless surface electromyography system were used to collect real-time data of side slip and forward slip. SPSS 20.0 univariate analysis of variance (ANOVA) was used to compare the differences of indicators between different groups. Results: In the side sliding movement, there were significant differences in hip motion (P<0.01) between 3-year-old group and 5-year-old group, hip motion(P<0.01) between 4-year-old group and 5-year-old group, knee motion(P<0.05) and ankle motion(P<0.05) between 3-year-old group and 5-year-old group. There was a significant difference in hip motion(P<0.05) between 3-year-old group and 5-year-old group. The Fx force(P<0.01) and vertical Fy force(P<0.01) in the left and right directions of the 3-year-old group and the 5-year-old group were significantly different in the side-slip movement, while the Fx force(P<0.01) in the right and left directions of the 3-year-old group and the 5-year-old group were significantly different in the forward-slip movement, and the vertical Fy force(P<0.05) was significantly different. There were significant differences in the long head of biceps femoris, gastrocnemius and anterior tibial muscle between 3-year-old group and 5-year-old group (P<0.05). There were significant differences in the middle gluteal muscle, gracilis muscle, adductor magnus, pubic muscle, medial femoral muscle and soleus muscle between 3-year-old group and 5-year-old group (P<0.05). There was significant difference in the anterior tibial muscle (P<0.05) between the 3-year-old group and the 5-year-old group in the supporting stage, and significant difference in the gastrocnemius muscle(P<0.05) during the swing stage. There was significant difference in the anterior tibial muscle(P<0.05) between the 3-year-old group and the 5-year-old group in the swing stage. Conclusion The development of side slip and forward slip in children aged 3 to 5 years old showed that the results suggest motor development increases significantly with age among preschoolers. Rhythmic movements of side slip and forward slip should be selected in the critical period of children’s movement development at different ages, laying the foundation for good physical and mental development.
