He had a history of ocular surgery with placement of glaucoma drainage implants (GDI), ultrasonic phacoemulsification, and intraocular lens implantation in both eyes. The patient had undergone a recent pars plana vitrectomy with complete panretinal photocoagulation (PRP) to clear vitreous hemorrhage in his right eye. To prevent progressive optic nerve damage, travoprost was tentatively administered because of inadequate intraocular pressure (IOP) control following surgery, laser treatment, and topical administration of many other IOP-lowering drugs. The patient experienced severe vision loss associated with acute anterior and intermediate uveitis. We consider it a rare complication due to the NVG patient’s vulnerability following ocular surgery. Given that acute uveitis developed rapidly and required time to resolve, systemic corticosteroid treatment could be considered to accelerate the resolution of inflammation.展开更多

Methods: A systematic review was performed by searching the databases of PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Web of Science. All studies published prior to November 30, 2022, comparing radiation dose and disease-related outcomes in EC patients. The hazard ratio (HR) and odds ratio (OR) were used to describe the risk of outcomes and toxicities. Results: Seven prospective trials involving 1124EC patients were enrolled for analyses. The results revealed that the effect on overall survival (HR = 0.99, 95% CI = 0.85 - 1.16, P = 0.94), local progression-free survival (HR = 0.83, 95% CI = 0.58 - 1.17, P = 0.29), local regional progression-free survival (HR = 0.94, 95% CI = 0.76 - 1.17, P = 0.61), progression-free survival (HR = 0.90, 95% CI = 0.71 - 1.13, P = 0.35) was similar in the high-dose and standard-dose groups. Additionally, a high radiation dose exhibited a potential disadvantage in respiratory toxicities when compared with a standard dose (4.8% vs 2.2%, OR 2.11, P = 0.06). Conclusions: The efficacy of the HD group (≥60 Gy) and the SD group (approximately 50 Gy) for inoperable local advanced EC was similar. However, the HD group exhibited a high radiation dose exhibited a potential disadvantage in respiratory toxicities when compared with a standard dose. Simultaneously, the final results of several ongoing prospective trials regarding the optimal radiation dose in dCRT are awaited.展开更多

文摘Aqueous zinc ion batteries(AZIBs)are one of the promising energy storage devices.However,uncontrolled dendrite and side reactions have seriously hindered its further application.In this study,the metal-organic framework(MOF)functionalized glass fiber separator(GF-PFC-31)was used to regulate interfacial behavior of zinc metal anode,enabling the development of high-performance AZIBs.In PFC-31,there areπ-πinteractions between two adjacent benzene rings with a spacing of 3.199 A.This spacing can block the passage of[Zn(H_(2)O)_6]^(2+)(8.6 A in diameter)through the GF-PFC-31 separator to a certain extent,which promotes the deposition process of Zn ions.In addition,the sulfonic acid group(-S03H)contained in GF-PFC-31 can form a hydrogen bonding network with H_(2)O,which can provide a desolvation effect and reduce the side reaction.Consequently,GF-PFC-31 separator achieves uniform deposition of Zn ions.The Zn‖GF-PFC-31‖Zn symmetric cell exhibits stable cycle life(3000 h at 1.2 mA cm^(-2),2000 h at 0.3 mA cm^(-2),and 2000 h at 5.0 mA cm^(-2)),and Zn‖GF-PFC-31‖MnO_(2) full cell with GF-PFC-31 separator can cycle for 1000 cycles at 1.2 A g^(-1)with capacity retention rate of 82.5%.This work provides a promising method to achieve high-performance AZIBs.

文摘Purpose: This study aimed to compare the survival benefits between different total radiation doses in definitive chemoradiotherapy (dCRT) for inoperable esophageal carcinoma (EC) based on modern radiotherapy techniques. Methods: A systematic review was performed by searching the databases of PubMed, EMBASE, Cochrane Central Register of Controlled Trials and Web of Science. All studies published prior to November 30, 2022, comparing radiation dose and disease-related outcomes in EC patients. The hazard ratio (HR) and odds ratio (OR) were used to describe the risk of outcomes and toxicities. Results: Seven prospective trials involving 1124EC patients were enrolled for analyses. The results revealed that the effect on overall survival (HR = 0.99, 95% CI = 0.85 - 1.16, P = 0.94), local progression-free survival (HR = 0.83, 95% CI = 0.58 - 1.17, P = 0.29), local regional progression-free survival (HR = 0.94, 95% CI = 0.76 - 1.17, P = 0.61), progression-free survival (HR = 0.90, 95% CI = 0.71 - 1.13, P = 0.35) was similar in the high-dose and standard-dose groups. Additionally, a high radiation dose exhibited a potential disadvantage in respiratory toxicities when compared with a standard dose (4.8% vs 2.2%, OR 2.11, P = 0.06). Conclusions: The efficacy of the HD group (≥60 Gy) and the SD group (approximately 50 Gy) for inoperable local advanced EC was similar. However, the HD group exhibited a high radiation dose exhibited a potential disadvantage in respiratory toxicities when compared with a standard dose. Simultaneously, the final results of several ongoing prospective trials regarding the optimal radiation dose in dCRT are awaited.
文摘Parkinson’s disease is a neurodegenerative disorder,and fe rroptosis plays a significant role in the pathological mechanism underlying Parkinson’s disease.Rapamycin,an autophagy inducer,has been shown to have neuroprotective effects in Parkinson’s disease.However,the link between rapamycin and ferroptosis in Parkinson’s disease is not entirely clear.In this study,rapamycin was administe red to a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinson’s disease mouse model and a 1-methyl-4-phenylpyridinium-induced Parkinson’s disease PC12 cell model.The results showed that rapamycin improved the behavioral symptoms of Parkinson’s disease model mice,reduced the loss of dopamine neurons in the substantia nigra pars compacta,and reduced the expression of ferroptosis-related indicators(glutathione peroxidase 4,recombinant solute carrier family 7,member 11,glutathione,malondialdehyde,and reactive oxygen species).In the Parkinson’s disease cell model,rapamycin improved cell viability and reduced ferro ptosis.The neuroprotective effect of rapamycin was attenuated by a ferroptosis inducer(methyl(1S,3R)-2-(2-chloroacetyl)-1-(4-methoxycarbonylphenyl)-1,3,4,9-tetrahyyridoindole-3-carboxylate)and an autophagy inhibitor(3-methyladenine).Inhibiting ferro ptosis by activating autophagy may be an important mechanism by which rapamycin exerts its neuroprotective effects.Therefo re,the regulation of ferroptosis and autophagy may provide a therapeutic target for drug treatments in Parkinson’s disease.

文摘BACKGROUND Selective laser trabeculoplasty(SLT)is a relatively safe and effective therapy in lowering intraocular pressures(IOP)for glaucoma.AIM To study the long-term effects of SLT on IOP and number of glaucoma medications used in Chinese eyes.METHODS This is a retrospective study in which 75 eyes of 70 patients with open-angle glaucoma(OAG,n=36)and eyes with prior glaucoma surgery(PGS,n=39)were included.Changes in mean IOP and number of glaucoma medications used evaluated at 1 d,1 wk,1 mo,3 mo,6 mo,12 mo,and 36 mo after laser treatment.RESULTS All patients(33 male,37 female)were Chinese.The mean age was 44.34±16.14years.Mean pre-SLT IOP was 22.75±2.08 mmHg in OAG and 22.52±2.62 mmHg in PGS.Mean IOP was significantly reduced 1 d,1 wk,1 mo and 3 mo after laser treatment(P<0.05,respectively).Whereas,there were no significant differences between baseline and SLT treated groups at the 6th month both in OAG(P=0.347,P>0.05)and in PGS(P=0.309,P>0.05).Six months after SLT treatment,some patients received retreatment of SLT or were given more topical IOP-lowering medication to control the IOP.By the end of our study,the average IOP decreased to 20.73±1.82 mmHg in OAG and 20.49±1.53 mmHg in PGS groups.The number of glaucoma medications used was significantly reduced until the end of 3 years compared to baseline.CONCLUSION SLT could reduce IOP as adjunctive treatment both in OAG and PGS groups.SLT significantly reduced the number of glaucoma medications used 3-years following treatment in glaucoma patients.
文摘目的:比较Tecnis Symfony连续视程人工晶状体与Zeiss三焦点人工晶状体(At Lisa tri 839MP)植入术后患者视觉质量的差异。方法:选取2019-01/2020-12于我院行白内障超声乳化吸除联合人工晶状体植入术的患者42例53眼,其中A组22例29眼植入Tecnis Symfony连续视程人工晶状体,B组20例24眼植入Zeiss三焦点人工晶状体。观察两组患者术后3mo时远中近视力,绘制离焦曲线,并评估生活质量,记录并发症发生情况。结果:术后3mo,两组患者视力均明显改善,两组患者裸眼远(5m)、中(80cm)距离视力及最佳矫正远距离视力(5m)无差异(均P>0.05),但B组患者裸眼中(60cm)、近(40cm)距离视力优于A组(均P<0.05)。术后3mo绘制离焦曲线示A组在+1.0~-2.0D段跨度平稳形成平台期;B组在0、-2.5D处形成两个波峰;0D处两组远视力无显著差异(P>0.05),-2.5、-3.5D处B组近视力显著优于A组(均P<0.01)。两组患者术后脱镜率均在90%以上,均出现不同程度眩光、光晕等光学现象,但生活质量总体满意度较高,A组阅读速度明显高于B组,且夜间视物满意度较高(均P<0.05)。结论:两种类型人工晶状体植入术后脱镜率均在90%以上,可为患者提供兼顾远、中、近的全程视力,Symfony连续视程人工晶状体植入术后流畅阅读及夜间视物满意度较高;Zeiss三焦点人工晶状体植入术后近距离视力更好,更适合近距离工作者。
