Expect the Unexpected: Report of a Case of Pediatric Pharyngeal Extraosseous Plasmacytoma with Tumefactive Amyloidosis (“Amyloidoma”) and a Review of the Literature

We report a rare case of localized pharyngeal tumefactive amyloidosis caused by extraosseous plasmacytoma in a 12 year-old girl who presented with otalgia, sore throat and blood stained sputum. The tumor was predominantly composed of amyloid with a limited component of well-differentiated neoplastic plasma cells, which were monoclonal (kappa restricted) on light chain in-situ hybridization. The amyloid deposits were positive for kappa immunoglobulin light chain on immunohistochemistry. The patient was treated with a combination of surgery and radiotherapy. Follow-up at 1 year showed no evidence of recurrence or progression.

Toll样受体2亚家族基因单核苷酸多态性与哮喘的关系研究

目的:探讨Toll样受体(Toll-like receptor,TLR)2亚家族基因单核苷酸多态性(single nucleotide polymorphisms,SNP)与中国东南方成人哮喘以及其临床表型之间的关系。方法:共招募哮喘患者318例,正常对照352例,TLR2亚家族中共8个SNP使用SNPstream方法进行了基因分型。对各SNP和单倍型与哮喘及其表型进行了分析。结果:运用Logistic回归分析后,发现rs7656411/TLR2突变基因型TT与野生型rs7656411 GG比较能明显降低37%哮喘的发生(校正OR=0.63,95%CI:0.41~0.98,P=0.41),rs7656411 TT+GT与哮喘无明显关系(校正OR=0.77,95%CI:0.54~1.09,P>0.05)。携有rs2381289/TLR6 T等位基因的哮喘患者患过敏性鼻炎的危险度为不携带此等位基因哮喘患者的1.79倍(95%CI:1.10~2.91,P=0.025),然而携有rs11466651/TLR10 A等位基因的哮喘患者患过敏性鼻炎的危险度较不携带此等位基因的哮喘患者下降了51%(95%CI:0.26~0.95,P=0.046)。结论 :TLR2亚家族基因的突变可能在哮喘易感性中起着重要作用。     

Acupoint injection therapy for diabetic retinopathy: A protocol for systematic review and meta-analysis

Background:Diabetic retinopathy (DR) is a common diabetic microvascular complication, and it is also the main cause of blindness in adults. At present, some studies have reported acupoint injection for the treatment of DR. However, the effectiveness and safety are still uncertain. This study aims to evaluate the efficacy and safety of acupoint injection for the treatment of patients with DR.Methods:The databases of English databases (PubMed, Embase, Cochrane Library, Web of Science) and Chinese databases (China National Knowledge Infrastructure, Chinese Scientific Journal Database, Wanfang Database, and Chinese Biomedical Literatures Database) will be retrieved. Published randomized controlled trials and quasi-randomized controlled trials on the topic will be retrieved by 2 investigators independently. We will apply a fixed-effect model or random effect model basis on the heterogeneity test and employ with RevMan 5.3 software for data synthesis. The total effective rate will be selected as the primary outcome, visual acuity, hemorrhage areas, exudates, capillary nonperfusion areas, hemorheological indicators, mean defect of visual field, glycated hemoglobin, and adverse events as secondary outcomes.Results:This study will comprehensively summarize the high-quality trials to determine the effectiveness and safety of acupoint injection treatment for patients with DR.Conclusion:The systematic review of this study will summarize the currently published evidence of acupoint injection treatment for DR to further guide its promotion and application.Protocol registration number:INPLASY2020110026     

Acupuncture therapy strategy options in postoperative management after laparoscopic cholecystectomy: A protocol for systematic review and Bayesian meta-analysis

Background:Laparoscopic cholecystectomy (LC) is a common surgery accompanied by some unpleasant adverse effects. Clinical trials indicated that acupuncture therapy may help reduce complications in LC. However, no systematic reviews have been conducted on the topic. Therefore, we will evaluate the current evidence and provide a rank for the efficacy of acupuncture therapy in LC by performing Bayesian network meta-analysis.Methods:A total of 9 databases will be searched from inception to 10 December 2020. Randomized control trails met the criterion will be included. Quality evaluation of included studies will be performed using Cochrane risk-of-bias tool. STATA 14.0, Addis 1.16.8, R 3.6.3, and OpenBUGS 3.2.3 will be used to conduct pairwise meta-analysis and network meta-analysis. The evidence will be assessed by the Grades of Recommendations Assessment Development and Evaluation.Results:This review will be based on clinical evidence to choose the best choice of acupuncture treatment for LC. And the results will be submitted to a peer-reviewed journal for publication.Conclusion:Through this systematic review, we will summarize the best available evidence of acupuncture therapy in LC and help to improve the clinical decision-making ability in LC domain.Systematic review registration:The protocol has been registered on INPLASY2020120056.     

TuYou-County Pediatric Eye (TYPE) study,design issues,baseline demographic characteristics,and implications: Report number 1

To report the rationale, design, and baseline demographic characteristics of TuYou-County Pediatric Eye study, which mainly aimed to determine the retinal microvascular changes with optical coherence tomography angiography (OCTA) and its association with eye abnormalities in school aged children and adolescents at suburban location in Northern China.TuYou-County Pediatric Eye study was a school-based survey conducted in TuYou-County. Multi-ethnic (Mongol, Han, and Hui) participants will be followed up for 5 years. Standardized ophthalmological examinations include visual acuity, ocular biometry, retinal photography, and OCTA. A questionnaire survey was conducted to collect variables regarding to eye disease such as parental history of eye diseases, near work, outdoor activities, living and eating habits, etc.After sampling, 687 participants were eligible for investigation, and 20 students did not attend the investigation, living 667 (response rate, 97.1%) students completed questionnaires and all ocular examinations. The average age of all participants was 14.9 ± 5.11.TYPE study is the first large-scale school-based multi-ethnic survey in suburban site of Northern China. Continuous identification of retinal microvascular changes with eye diseases will provide new insights into the control related diseases in school-age children and adolescents.

Remote patient monitoring sustains reductions of hemoglobin A1c in underserved patients to 12 months

AimsWe sought to determine whether underserved patients enrolled in a statewide remote patient monitoring (RPM) program for diabetes achieve sustained improvements in hemoglobin A_1c at 6 and 12 months and whether those improvements are affected by demographic and clinical variables.MethodsDemographic and clinical variables were obtained at baseline, 6 months and 12 months. Baseline HbA1c values were compared with those obtained at 6 and 12 months via paired t-tests. A multivariable regression model was developed to identify patient-level variables associated with HbA_1c change at 12 months.ResultsHbA_1c values were obtained for 302 participants at 6 months and 125 participants at 12 months. Compared to baseline, HbA_1c values were 1.8% (19 mmol/mol) lower at 6 months (p < 0.01) and 1.3% (14 mmol/mol) lower at 12 months (p < 0.01). Reductions at 12 months were consistent across clinical settings. A regression model for change in HbA_1c showed no statistically significant difference for patient age, sex, race, household income, insurance, or clinic type.ConclusionsPatients enrolled in RPM had improved diabetes control at 6 and 12 months. Neither clinic type nor sociodemographic variables significantly altered the likelihood that patients would benefit from this type of technology. These results suggest the promise of RPM for delivering care to underserved populations.
