Data will be analyzed using the statistical software package SPSS version 18.0 (Chicago, IL). This study will evaluate the clinical efficacy of a silver needle in the treatment of rheumatoid arthritis. The results of this study will provide a reliable reference for the clinical use of a silver needle in the treatment of rheumatoid arthritis. OSF Registration number DOI 10.17605/OSF.IO/4X5QB.

In recent years, its incidence is increasing year by year, and its morbidity and mortality rank the first place among female malignant tumors. Some key enzymes and intermediates in glycolysis are closely related to tumor development. Pyruvate kinase M2 (PKM2) is an important rate-limiting enzyme in glycolysis pathway. Meanwhile, it is highly expressed in proliferative cells, especially in tumor cells, and plays an important role in the formation of Warburg effect and tumorigenesis. Previous studies have explored the effects of PKM2 expression on the prognosis and clinical significance of breast cancer patients, while the results are contradictory and uncertain. This study uses controversial data for meta-analysis to accurately evaluate the problem. We collected relevant Oncomine and The Cancer Genome Atlas (TCGA) data to further verify the results. Through bioinformatics analysis, the mechanism and related pathways of PKM2 in breast cancer are explored. nferences. DOI 10.17605/OSF.IO/W52HB. DOI 10.17605/OSF.IO/W52HB. Leptomeningeal collateral flow (LMF) is associated with infarct area and clinical outcome for ischemic stroke patients. Although LMF can be detected by multiple imaging methods, but their diagnostic performance is uncertain.The aim of this study was to evaluate the diagnostic validity or reliability of noninvasive image methods in assessing LMF.Databases included PubMed, Web of Science, Embase, and Cochrane Library.Original observational cohort studies.Ischemic stroke patients.Different noninvasive image methods to assess LMF.Newcastle-Ottawa Scale to evaluate the quality of the studies; forest plot to show pooled results; I2 and Egger test to evaluate the heterogeneity and publication bias.Thirty of the 126 selected studies were eligible. For CT angiography, the interobserver agreement ranged from 0.494 to 0.93 and weighted kappa was 0.888; for patients receiving thrombolysis or endovascular treatment, 0.68 to 0.91; 0.494 to 0.89 for the 2-point system, 0.60 to 0.93 for the 3-point system, 0.68 to 0.87 forhods had better validity and reliability to evaluate LMF of patients receiving thrombolysis or endovascular treatment than all ischemic stroke patients. Ectopic tooth is tooth erupting out of normal anatomical position. Ectopic tooth can occur in different positions, such as maxillary sinus and nasal cavity. In this article, we present a rare case of an ectopic tooth with a dentigerous cyst in the maxillary sinus compressing the nasolacrimal canal. An 8-year-old girl presented with a 2-month history of spontaneous lacrimation in her right eye. When she wept, more tear shed from her right eye than that from the left one. Computed tomographic (CT) imaging showed a huge low-density image containing a tooth in the maxillary sinus in her right maxilla; the right nasolacrimal canal vanished due to the compression of the ectopic tooth. Ectopic tooth with dentigerous cyst of right maxilla, and obstruction of nasolacrimal duct. The patient underwent nasal endoscopic maxillary sinus cystectomy. The patient recovered well after cystectomy and has been symptom-free. The unique finding is that this is the first report about ectopic tooth compressing the nasolacrimal canal and inducing spontaneous lacrimation. Treatment aspect surgery under endoscope is a minimally invasive approach to ectopic tooth.

The argument on the efficacy of medical nutritional therapy and comprehensive nutritional care remains to be resolved. Therefore, we conducted this protocol of systematic review and meta-analysis to evaluate the efficacy between medical nutritional therapy and comprehensive nutritional care for patients with gestational diabetes mellitus (GDM). We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols reporting guidelines and the recommendations of the Cochrane Collaboration to conduct this study. Reviewers will search the PubMed, Cochrane Library, Web of Science, and EMBASE online databases using the key phrases "gestational diabetes mellitus," "comprehensive nutrition care," and "medical nutritional therapy" for all cohort studies published up to May 20, 2021. There is no restriction in the dates of publication or language in the search for the current review. The studies on cohort study focusing on comparing medical nutritional therapy and comprehensive nutrition care for GDM patients will be included in our meta-analysis. The outcomes include blood glucose levels, complications, weight change, and incidence of cesarean section. Where disagreement in the collection of data occurrs, this will be resolved through discussion. We hypothesized that these 2 methods would provide similar therapeutic benefits. 10.17605/OSF.IO/SC8HJ. 10.17605/OSF.IO/SC8HJ. Peripheral facial paralysis (PFP) is a common peripheral neural disease. Acupuncture treatment combined with PFP rehabilitation exercises is a routine method of PFP treatment. This article is to provide a new visual and objective evaluation method for exploring the mechanism and efficacy of acupuncture treatment on PFP, and develop an interactive augmented facial nerve function rehabilitation training system with multiple training models. This prospective and observational trial will recruit 200 eligible participants for the following study. https://www.selleckchem.com/products/Decitabine.html In the trial, the laser speckle contrast analysis (LASCA) technology will be applied to monitor the microcirculation of facial blood flow during acupuncture, and real-time monitoring algorithms, data sampling, and digital imaging methods will be conducted by machine learning and image segmentation. Then, a database of patient facial expressions will be built, the correlation between surface blood flow perfusion volume and facial structure symmetry will be analyzed, combined with scale assessment and electrophysiological detection.
