Delayed infected hematoma in retrosternal area following total thyroidectomy: a case report.

Introduction And Importance: Postoperative neck hematoma (PNH), a rare complication following thyroidectomy, occurs in only 1.1-3.15% of cases and can lead to life-threatening outcomes.

Retraction: Salidroside inhibits the proliferation and migration of gastric carcinoma cells and tumor growth the activation of ERS-dependent autophagy and apoptosis.

Giant lipoma in the Retzius space resected under laparoscopy: A case report.

Lipoma is a common type of benign soft tissue tumor that can occur in the shoulders, neck and back, in addition to other body parts. The Retzius space is a small anatomical space between the pubic symphysis and the bladder located extraperitoneally and filled with loose fatty connective tissue. Giant lipomas are rare in the Retzius space.

Phase drift and noise suppression method based on SEE-SGMD-PCC in a distributed acoustic sensor.

The problems of laser source frequency drift (LSFD) and phase noise in distributed acoustic sensor (DAS) make it difficult to recover the true vibration phase curve, which limits its application scope in the field of seismic exploration. In order to suppress the influence of phase noise and phase drift on the phase signal and improve the signal-to-noise ratio (SNR) of the phase curve, this paper proposes a method based on symmetric extreme value expansion, symplectic geometry mode decomposition and Pearson correlation coefficient (SEE-SGMD-PCC). Firstly, the mathematical principles and processing flow of the SEE-SGMD-PCC algorithm were introduced, and the effectiveness of this method was verified through multiple sets of simulation experiments.

An Assessment of the Effect of Bariatric Surgery on Cardiovascular Disease Risk in the Chinese Population Using Multiple Cardiovascular Risk Models.

Background: Many studies have reported that bariatric surgery may reduce postoperative cardiovascular risk in patient with obesity, but few have addressed this risk in the Chinese population.

Objective: To assess the impact of bariatric surgery on cardiovascular disease (CVD) risk in the Chinese population using the World Health Organization (WHO) risk model, the Global risk model, and the Framingham Risk Score.

Methods: We retrospectively analyzed data collected on patient with obesity who underwent bariatric surgery at our institution between March 2009 and January 2021.

Association between microbiological risk factors and neurodegenerative disorders: An umbrella review of systematic reviews and meta-analyses.

Unlabelled: The role of microbiological factors in the development of neurodegenerative diseases is attracting increasing attention, while the relationship remains debated. This study aimed to comprehensively summarize and evaluate the associations between microbiological factors and the risk of neurodegenerative disorders with an umbrella review. PubMed, Embase, and the Cochrane library were used to search for papers from the earliest to March 2021 for identifying meta-analyses and systematic reviews that examined associations between microbiological factors and neurodegenerative diseases.

Risk factors of secondary infection/recurrence after ablation for liver cancers: A systemic review and meta-analysis.

Background: This study aimed to systemically explore the risk factors of secondary infection/recurrence after ablation in patients with liver cancer.

Methods: Relevant literature in PubMed, EMbase, and Cochrane Library databases were searched with keywords including "liver cancer or carcinoma," "ablation," "infectious or infection or recurrence," and "risk factor or relevant factor or correlative factor or influencing factor." Meta-analyses were performed and forest plots were drawn for risk factors, including the tumor size and location, number of tumor nodules, hepatitis B virus (HBV) DNA levels, serum alpha fetal protein (AFP) levels and serum albumin levels, Child-Pugh Class, and lack of antiviral therapy.

Development of a laser scanning projection system with a dual-diameter fitting method and particle swarm optimization.

Laser scanning projection can project outlines of assembled components onto a work surface accurately, which can improve assembly efficiency, and is widely applied in industry manufacturing. In order to achieve accurate calibration and projection, a mathematical model of the calibration process is developed, and the dual-diameter fitting method is proposed to extract the central positions of retroreflective targets. Then, a particle swarm optimization (PSO) algorithm is introduced to solve the coordinate transformation matrix between the world frame and the projector frame, and the optimal parameters of the PSO algorithm are obtained to improve the convergence probability of the transformation matrix solutions.

LncRNA LINC00689 Promotes the Progression of Gastric Cancer Through Upregulation of ADAM9 by Sponging miR-526b-3p.

Introduction: Increasing studies have demonstrated that noncoding RNAs, including miRNAs and lncRNAs, have vital roles in mediating cancer progression. However, the expression features and biological functions of LINC00689 in gastric cancer (GC) remain largely unknown. This study was designed to investigate the functions of LINC00689, miR-526b-3p and ADAM9 as well as their interactions in GC.

Salidroside inhibits the proliferation and migration of gastric carcinoma cells and tumor growth the activation of ERS-dependent autophagy and apoptosis.

The endoplasmic reticulum stress (ERS)-induced autophagy and apoptosis are favorable for the suppression of many cancer types. Salidroside (Salid) has been proven to be capable of inducing the apoptosis of many cancer cells. However, the underlying mechanisms and whether Salid can activate the autophagic system have still not been explained thoroughly.
