Pyroptosis is a newly discovered form of programmed cell death, which has a close relationship with infectious diseases and spontaneous inflammatory disease and autoimmune disease.Gasdermin-D is the effector of pyroptosis.Inflammatory caspases cleave Gasdermin-D, break the structural autoinhibition and active the pore-forming activity of Gasdermin-D.Gasdermin-D-N domain is the active form of Gasdermin-D.Oligomerized Gasdermin-D-N domain forms membrane pores.Both pyroptosis and necroptosis can form pores.In this article, the progress of the research on pyroptosis, the involvement of Gasdermin-D in the molecular mechanism of pyroptosis, the distinguishment of pyroptosis from necroptosis and pyroptosis-related diseases are reviewed.

Objective To investigate the effect of methylprednisolone pulse therapy on spinal nerve functions in patients with acute spinal cord injury (ASCI) and evaluate its safety. Methods 200 patients with ASCI treated in our hospital from January 2010 to December 2016 were selected and were randomly divided into two groups,with 100 cases each group. The patients in control group were treated with routine basic treatment while patients in the study group were treated with methylprednisolone pulse therapy. On the basis of the American spinal cord injury Society scoring criteria (ASIA), the neurological functional recovery scores were performed were scored before and 6 weeks after treatment between the two groups and the adverse reactions were recorded. Results The scores of sensory and motor function of the patients in the two groups were higher than those before the treatment and there was statistical difference (P<0.05), and the scores in the study group was significantly higher than those in the control group, and the difference between the two grouPs was statistically significant (P<0.05). The incidence of adverse reactions in the study group (25.00％) was significantly higher than that in the control group (10.00％), and the difference was statistically significant (P<0.05). The incidence of lung infection and gastrointestinal reaction in the study group were significantly higher than those in the control group and there were statistical difference (P<0.05). Conclusion Methylprednisolone pulse therapy has significant effect on the recovery of neurological function in patients with ASCI, but the incidence of adverse reactions is high, so it is necessary to strengthen the monitoring and intervention in clinic.

Objective To compare the effects of target-controlled infusion(TCI) of remifentanil in three different doses in thoracic patients undergoing total intravenous anesthesia.Methods Forty-five ASA Ⅰ～Ⅱ patients aged 40～60yr undergoing thoracic surgery were randomly divided into three groups.The patients were given midazolam 0.05mg/kg and artropine 0.5 mg/kg i.m.before anesthesia.Anesthesia was induced with remifentanil and propofol both given by TCI simultaneously.The target concentration of propofol was set at 3?g/ml and remifentanil at 4,6,8ng/ml(groupⅠ,Ⅱ,Ⅲ).When the patients lost conscionsness,rocuronium 0.6mg/kg was given i.v.to facilitate intubation.Anesthesia was maintained with TCI of propofol-remifentanil and intermittent i.v.boluses of rocuronium.Remifentanil target concentration maintained unchanged during anesthesia.BIS index was controlled at 45～55 by modify propofol target concentration.SBP,DBP,MAP,HR and BIS index was recorded in baseline(T0),before intubation(T1),intubation(T2),skin incision(T3),the opening of the chest(T4),skin closuer(T5),extubation(T6).Vein blood samples were taken for determination of plasma concentration of epinephrine(E) and norepinephrine(NE) by ELASA.Results SBP,DBP,MAP,HR and plasma NE concentration at T2,T3,T4,T5 were higher than T0 in group Ⅰ(P

AIM: To investigate the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) drug Bevacizumab on connective tissue growth factor(CTGF) and pigment epithelium derived factor (PEDF) in proliferative membranes in patients with proliferative diabetic retinopathy (PDR).METHODS: From January 2015 to December 2016, 117 patients (126 eyes) with PDR were analyzed using the case-control study.The selected cases were randomly divided into two groups, respectively, Group A of 60 cases (63 eyes) and Group B of 57 cases (63 eyes).The Group A was treated with vitrectomy alone, while the Group B received intravitreal injection of 0.05mL/1.25mg bevacizumab before vitrectomy.The peeled epiretinal membranes in patients were stained and then the histopathological changes were observed for primitive cells and angiogenesis, the expression of CTGF and PEDF were tested.RESULTS: The expression of CTGF and PEDF in the proliferative membrane of the two groups were expressed in the cytoplasm.The Group A showed positive expression in 38 cases, the positive rate was 60.3%.Compared with Group A, the positive expression rate of CTGF in Group B (92.1%) was significantly higher (P<0.05).The positive expression rates of PEDF in the two groups were 90.5% and 95.2% respectively, and there was no significant difference between the two groups (P>0.05).CONCLUSION: In patients with PDR after intravitreal injection of bevacizumab, the retinal neovascularization is significantly reduced, which is conducive to vitrectomy.The positive expression rate of CTGF significantly increased in patients with PDR after intravitreal injection of bevacizumab, but there was no significant change in the expression of PEDF in the anterior membrane.

AIM: To study the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) on best corrected visual acuity (BCVA) and multifocal-electroretinogram (mfERG) before and after treatment for choroidal neovascular disease.METHODS: A total of 264 patients (332 eyes) with macular neovascularization (MCNV) and idiopathic choroidal neovascular disease (ICNV) who underwent pathologic myopia from January 2015 to January 2017 were enrolled in this study.Intraocular pressure and BCVA, fundus using 90D front mirror and slit lamp detection, and the fundus photograph, OCT, ICGA and FFA angiography, mfERG detection were taken.One month after the drug, 1mo after the final treatment, we recorded BCVA, intraocular pressure and mfERG and so on.RESULTS: Ranibizumab was injected into the 254 eyes, and 78 eyes were injected with conbercept.There were 37 eyes injected once, 147 eyes were injected twice, 72 eyes were injected 3 times, 57 eyes were injected 4 times, 19 eyes 5 times.There were no significant differences on intraocular pressure between the two groups (P>0.05).The BCVA before treatment was significantly different compared with those 1mo after treatment and 1mo after the final treatment (P>0.05).The amplitude of Ring1, Ring2 and Ring4 increased after treatment, the difference was statistically significant.(P<0.05).The amplitude of Ring3 and Ring5 increased at 1mo after final treatment(P<0.05).CONCLUSION:Intravitreal injection of anti-VEGF drugs has a significant effect on BCVA and mf ERG in patients with choroidal neovascular disease and is safe.

Interleukin-10 (IL-10) is an immuno-regulatory cytokine,which is well known for its immunosuppressive function.IL-1O can act on a variety of immune cell subsets and play an immunosuppressive effect through a variety of ways.It plays an important role in the tumor immune escape.Recent studies show that IL-10 also has an immune-stimulating function,which is presumably a pluripotent cytokine.This paper will combine the latest literature to summary the positive and negative regulatory roles of IL-10,mediation ways in the tumor and the relationships with prognosis.

Objective To investigate the effects of ventilation strategy of permissive hypercapnia on the expression of inflammatory mediators in the patients received laparoscopic radical gastrectomy. Methods Thirty-six patients received laparoscopic radical gastrectomy were randomly divided into two groups: control group and experiment group. The patients in control group received conventional ventilation strategy [partial pressure of carbon dioxide in endexpiratory gas (P<,ErCO2) 34.5-45.0 mm Hg (1 mm Hg =0.133 kPa),pH7.35-7.45], and patients in experiment group received ventilation strategy of permissive hypercapnia(PErCO2 49.5-60.0 mm Hg,pH7.20). Blood samples were collected respectively from the peripheral vein before anesthesia induction (T0), 1 h (T1), 3 h (T2) after operation and when operation finished (T3) for the assessment of interleukin(IL)-8, IL-6,tumor necrosis factor (TNF)- α. Results The levels of IL-8, IL-6, TNF-α at T2, T3 were higher in control group [(96.732±3.173) μg/L and (107.767±3.654) μg/L, (0.273±0.009 ) ng/L and (0.287±0.008) ng/L,(1.443±0.086)μg/L and (1.614±0.107) μg/L] than those in experiment group [(91.771±4.332) μ g/L and (97.682±4.998) μg/L, (0.231±0.008 ) ng/L and (0.241±0.006) ng/L,(1.268±0.066) μg/Land (1.428±0.058) μg/L](P<0.05 or <0.01), mean arterial pressure, partial pressure of oxygen in artery and heart rate were relative stabilization. Conclusions Ventilation strategy of permissive hypercapnia can reduce the released amount of inflammatory mediators and may be advantageous for the patients received laparoscopic radical gastrectomy.

BACKGROUND:Alendronate has a marked enhancing effect on bone mineral density. Ibandronate is the newest (the third generation) bisphosphonates. Evidence-based medicine data on the therapeutic effects ofboth twodrugs remain lacking because of different administration routes and time.
OBJECTIVE:To compare the therapeutic effects of ibandronate and alendronate on postmenopausal osteoporosis.
METHODS:A computer-based online search was conducted in CNKI, PubMed, CECDB, BMA, VIP, CQVIP, CBM, EMbase, ASP, The Cochrane Library, and EMCC databases from August 1999 toAugust 2015 to screen the relevant randomized controled trials. Meta-analysis was performed using Stata/SE version 12.0 software by extracting data from the relevant articles.
RESULTS AND CONCLUSION:A total of 10 randomized controlled trials involving 725 patients (ibandronate and alendronate for 379 and 346 patients, respectively) were included. The meta-analysis results showed that bone mineral density was significantly increased (P=0.174, I2=29.4%,WMD=0.03, 95%CI (0.01-0.04))at 6 months after treatment and incidence rate of fracture was significantly decreased(P=5.810,I2=0%,OR=0.32, 95%CI:(0.10-1.00))during 1-year treatment with ibandronate compared with alendronate treatment. However, no significant differences were found between two drug treatmentsin lumbar spine bone mineral density at 1 year after treatment and the incidence rate of fracture during 6-month treatment. Six-month treatment ofibandronate can improve bone mineral density and reduce the incidence rate of fracture of patients withpostmenopausal osteoporosis.
