Dose-Response Relationship of GLP-1 Receptor Agonists on HbA1c and Body Weight in Type 2 Diabetes Mellitus: A Systematic Review and Network Meta-Analysis.

Objective: To explore the dose-response relationship of GLP-1 RAs in reducing HbA1c, body weight, and incidence of adverse events among T2DM patients.

Methods: This systematic review and network meta-analysis followed the PRISMA guidelines. We conducted a systematic search of PubMed, Medline, Embase, Cochrane Central Register of Controlled Trials, and Web of Science for articles published up to October 20, 2024.

Hyperthyroidism and severe bradycardia: Report of three cases and review of the literature.

Background: Hyperthyroidism often leads to tachycardia, but there are also sporadic reports of hyperthyroidism with severe bradycardia, such as sick sinus syndrome (SSS) and atrioventricular block. These disorders are a challenge for clinicians.

Case Summary: We describe three cases of hyperthyroidism with SSS and found 31 similar cases in a PubMed literature search.

Research hotspots and development trends of microRNA in ischemia-reperfusion: network analysis of academic journals oriented by bibliometric and visualization.

Background: Ischemia-reperfusion (IR) injury can occur in the heart, brain, liver, lung, kidney, and other important organs, and may greatly increase disease mortality. MicroRNAs (miRNAs) have a variety of functions, including regulating cell differentiation, proliferation, and apoptosis. In the past 10 years, many studies on miRNAs in IR have been conducted.

[Relationship between polymorphism of parathyroid hormone and bone mineral density and relevant biochemical indicators in women].

Objective: To investigate the distribution of parathyroid hormone (PTH) gene polymorphisms and the relationships of PTH gene polymorphisms with bone mass and serum bone relative biochemical markers.

Methods: Blood samples of 314 normal female volunteers, aged 20 - 80, were collected. Serum PTH, bone alkaline phosphatase (sBAP), cross-linked N-telopeptide of collagen type I (sNTX), cross-linked C-telopeptide of collagen type I (sCTX), osteoprotegerin (OPG) and leptin were determined by ELISA.

Age-related changes of serum bone alkaline phosphatase and cross-linked C-telopeptides of type I collagen and the relationship with bone mineral density in Chinese women.

Background: Previous studies have shown that bone turnover rate changes with age. At the same time, there is no definitive research regarding age-related changes of bone turnover level and its association with bone mineral density (BMD) in Chinese mainland women.

Methods: In a cohort of 663 Chinese mainland women aged 20-70 years, serum bone alkaline phosphatase (BAP) and serum cross-linked C-telopeptides of type I collagen (sCTX) were measured to evaluate the state of bone formation and resorption, respectively.

Comparison of spine and femur reference data in native Chinese women from different regions of China.

The aim of this study is to explore the differences of BMD reference curves at various skeletal sites among Chinese women from different regions of China and to investigate the feasibility of establishing a unified national BMD reference database for Chinese women. We measured BMD at the posteroanterior (PA) lumbar spine, femoral neck, trochanter and Ward's triangle by dual-energy X-ray absorptiometry bone densitometer in 3,422 Changsha women of South Central China, aged 20-84 years. The documented BMDs of reference populations of women in all other areas included Shanghai ( n =2,111) and Nanjing ( n =3,174) in the East, Shenyang ( n =1,213) in the Northeast, Kunming ( n =523) in the Southwest, Chongqing ( n =811) in the Midwest and Xian ( n =1,320) in the Northwest.

[Pathology and molecular pathogenesis of spondyloepiphyseal dysplasia tarda with progressive arthropathy caused by compound CCN6 heterogeneous gene mutations].

Objective: To characterize the clinical manifestations, features of roentgenography and MR imaging, and the pathology of articular cartilage and matrix of spondyloepiphyseal dysplasia tarda with progressive arthropathy (SEDT-PA), to screen the mutations of the disease-causing CCN6 gene, and try to elucidate the molecular pathogenesis of SEDT-PA.

Methods: A questionnaire survey on the clinical manifestations and history was conducted among a pedigree of SEDT-PA with 57 persons (53 living members) in tolal, including 2 probands, a 19-year old female and a 9-year old male. Physical examination and roentgenography and MR imaging were used on the 2 probands to characterize the features of their joints and articular cartilage.

[Serum osteoprotegrin and serum bone gamma-carboxyglutamine acid-containing protein are correlated with bone mineral density in normal women].

Objective: To study the relationships of serum osteoprotegrin (sOPG), serum bone gamma-carboxyglutamine acid-containing protein (sBGP), and urine deoxypyridinoline (uDPD)/creatinine (Cr) with age and bone mineral density (BMD) in women.

Methods: ELISA was used to examine the sOPG, sBGP, and uDPD/Cr of 672 female volunteers aged 20-80. The BMD (QDR4500A) value of the anteroposterior lumbar spine and femoral neck were measured by DXA.
