The Relationship Between Mercury Exposure and Membranous Nephropathy: Case Reports and Meta-Analysis.

To investigate the clinical characteristics of patients with membranous nephropathy (MN) and the therapeutic efficacy of Sodium Dimercaptosulphonate (DMPS), as well as the relationship between mercury (Hg) exposure and MN, we investigated the clinical manifestations and treatment outcomes of six patients with MN and searched the China National Knowledge Internet (CNKI), PubMed, Web Of Science, and Embase databases for relevant studies on Hg exposure and MN published from the inception of the databases to April 2024. Data analysis was performed using SPSS 26.0 and Stata 16.

Spatial analysis and influencing factors of pulmonary tuberculosis among students in Nanning, during 2012-2018.

Background: Economically underdeveloped areas in western China are hotspots of tuberculosis, especially among students. However, the related spatial and temporal patterns and influencing factors are still unclear and there are few studies to analyze the causes of pulmonary tuberculosis in students from the perspective of space.

Methods: We collected data regarding the reported incidence of pulmonary tuberculosis (PTB) among students at township level in Nanning, from 2012 to 2018.

[Color distribution of the anterior teeth in 137 elder people].

Purpose: To study the color distribution of the anterior teeth in elder people.

Methods: 612 anterior teeth from 137 people aging from 60 to 81 years and 200 anterior teeth from 100 young people aging from 20 to 40 years were collected. A digital colorimeter was used to measure the value of L*,a*,b* of the teeth, and the chromatism (deltaE) was calculated according to the formula deltaE=(deltaL*(2)+deltaa*(2)+deltab*(2))1/2.

[The influence of the try-in pastes on the colour of all-ceramic veneers].

Purpose: To study the influence of the try-in pastes on the color of all-ceramic veneers made by Ips-empress II system.

Methods: 50 discolored teeth were collected and restored with all-ceramic veneers. Five try-in pastes including A1, A3, transleucent(Trt), white opaque(WOT) and B0.

[A preliminary study on the relationship between the wearing time of full denture and EMG in edentulous patients].

Purpose: This study was aimed to analyze the relationship between the periods of wearing time of full denture and function of mastication in edentulous patients.

Methods: Electromyogram (EMG) was done at an initial time of wearing full denture for 30 patients (Group A) and at an interval of wearing full denture for more than 3 months for 32 patients (Group B). EMG activities were recorded for 2 pairs of muscles (anterior temporalis, masseter) by means of Medelec Synergy Electromyography.
