BACKGROUND Various non-steroidal anti-inflammatory drugs(NSAIDs)have been used for juvenile idiopathic arthritis(JIA).However,the optimal method for JIA has not yet been developed.AIM To perform a systematic review and network meta-analysis to determine the optimal instructions.METHODS We searched for randomized controlled trials(RCTs)from PubMed,EMBASE,Google Scholar,CNKI,and Wanfang without restriction for publication date or language at August,2023.Any RCTs that comparing the effectiveness of NSAIDs with each other or placebo for JIA were included in this network meta-analysis.The surface under the cumulative ranking curve(SUCRA)analysis was used to rank the treatments.P value less than 0.05 was identified as statistically significant.RESULTS We included 8 RCTs(1127 patients)comparing 8 different instructions including meloxicam(0.125 qd and 0.250 qd),Celecoxib(3 mg/kg bid and 6 mg/kg bid),piroxicam,Naproxen(5.0 mg/kg/d,7.5 mg/kg/d and 12.5 mg/kg/d),inuprofen(30-40 mg/kg/d),Aspirin(60-80 mg/kg/d,75 mg/kg/d,and 55 mg/kg/d),Tolmetin(15 mg/kg/d),Rofecoxib,and placebo.There were no significant differences between any two NSAIDs regarding ACR Pedi 30 response.The SUCRA shows that celecoxib(6 mg/kg bid)ranked first(SUCRA,88.9%),rofecoxib ranked second(SUCRA,68.1%),Celecoxib(3 mg/kg bid)ranked third(SUCRA,51.0%).There were no significant differences between any two NSAIDs regarding adverse events.The SUCRA shows that placebo ranked first(SUCRA,88.2%),piroxicam ranked second(SUCRA,60.5%),rofecoxib(0.6 mg/kg qd)ranked third(SUCRA,56.1%),meloxicam(0.125 mg/kg qd)ranked fourth(SUCRA,56.1%),and rofecoxib(0.3 mg/kg qd)ranked fifth(SUCRA,56.1%).CONCLUSION In summary,celecoxib(6 mg/kg bid)was found to be the most effective NSAID for treating JIA.Rofecoxib,piroxicam,and meloxicam may be safer options,but further research is needed to confirm these findings in larger trials with higher quality studies. 展开更多

Citation:Xu QQ,Wang WW,Zhu J,Liu JR.An unusual case of malignant glaucoma with ciliary detachment.Int J Ophthalmol 2021;14(12):1988-1992 Dear Editor,I am writing this letter to present an unusual case of malignant glaucoma with ciliary detachment.Malignant glaucoma has an incidence of 0.6%-4%and mostly occurs after filtering surgery for primary angle-closure glaucoma.After surgery,the intraocular pressure(IOP)does not decrease but increases,and the anterior chamber(AC)becomes shallower or disappears.There is an obvious ophthalmodynia,and the disease rapidly worsens,thus seriously threatening the visual function of patients[1-3].So far,no cases of malignant glaucoma combined with ciliary detachment have been reported.Complete comprehension of the symptoms of malignant glaucoma with ciliary detachment is crucial for preserving the patients’visual function,diagnosing the disease at the early stage,and conducting correct and effective treatment. 展开更多

Objective:Moxibustion,a common therapy in traditional Chinese medicine,has potential benefits for treating decreased ovarian reserve(DOR).The present study investigates the protective effect of moxibustion in a rat model of DOR and explores the possible mechanisms.Methods:Sixty-four female Sprague-Dawley rats were randomly divided into four groups:control,DOR,moxibustion(MOX),and hormone replacement therapy(HRT).The DOR rat model was established by intragastric administration of 50 mg/kg Tripterygium glycoside suspension(TGS),once daily for 14 days.MOX and HRT treatments were given from the day TGS administration was initiated.The ovarian reserve function was evaluated by monitoring the estrus cycle,morphological changes in ovaries,levels of serum estradiol(E2),follicle-stimulating hormone(FSH),luteinizing hormone(LH),and anti-Mullerian hormone(AMH),pregnancy rate and embryo numbers.Terminal-deoxynucleotidyl transferase-mediated nickend-labeling staining was used to identify ovarian granulosa cell apoptosis,while the protein and m RNA expressions of Bax,B-cell lymphoma-2(Bcl-2),phosphatidylinositol 3-kinase(PI3 K)and protein kinase B(AKT)in ovarian tissues were examined by immunohistochemistry,Western blot and quantitative reverse transcription-polymerase chain reaction.Results:Compared with the DOR group,MOX improved the disordered estrous cycle,promoted follicular growth,reduced the number of atresia follicles,increased the concentrations of serum E2 and AMH,and decreased serum FSH and LH concentrations.More importantly,the pregnancy rate and embryo numbers in DOR rats were both upregulated in the MOX treatment group,compared to the untreated DOR model.Further,we found that the MOX group had reduced apoptosis of ovarian granulosa cells,increased Bcl-2 expression and reduced expression of Bax.Furthermore,the PI3 K/AKT signaling pathway was triggered by the moxibustion treatment.Conclusion:Moxibustion improved ovarian function and suppressed apoptosis of ovarian granulosa cells in a rat model of DOR induced by TGS,and the mechanism may involve the PI3 K/AKT signaling pathway. 展开更多

Implant-associate infection(IAI)is a major cause of failure of bone implant materials,and one of the significant challenges in clinical managements.A synergistic coating strategy combining montmorillonite(MMT)sustained release,adsorption of bacteria and gentamicin(GS)bactericidal is proposed herein to tackle infection issues.Surface morphology,microstructure and chemical composition of the samples were investigated using SEM,XRD,FT-IR and XPS.Electrochemical experiments and immersion experiments reveal that corrosion resistance of Mg samples with GS/MMT coatings was higher than that of bare Mg alloy substrate in DMEM solution.In vitro studies demonstrated that the GS/MMT coating had a significant inhibitory effect on Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus).The viability of MC3T3-E1 cells was 92.7%after a co-culturing for 72 h.After a subcutaneous transplantation of 90days,the survival rate was 100%for GS/MMT-coated Mg alloy specimens with no infection at the implantation sites and no toxic damage to liver,kidney and local muscles pathological sections.This study provides a novel method for the preparation of sustained-release antimicrobial coatings on biodegradable Mg alloys as promising candidates for orthopedic implant materials. 展开更多

Magnesium alloys as a new class of biomaterials possess biodegradability and biocompatibility in comparison with currently used metal implants. However, their rapid corrosion rates are necessary to be manipulated by appropriate coatings. In this paper, a new attempt was used to develop a zinc-calcium phosphate (Zn-Ca-P) conversion coating on Mg-1.33Li-0.6Ca alloys to increase the biocompatibility and improve the corrosion resistance. In vitro blood biocompatibility of the alloy with and without the Zn-Ca-P coating was investigated to determine its suitability as a degradable medical biomaterial. Blood biocompatibility was assessed from the hemolysis test, the dynamic cruor time test, blood cell count and SEM observation of the platelet adhesion to membrane surface. The results showed that the Zn-Ca-P coating on Mg-1.33Li-0.6Ca alloys had good blood compatibility, which is in accordance with the requirements for medical biomaterials. 展开更多
