Risk Factors of New Symptomatic Fractures After Vertebroplasty: A Retrospective Cohort Study of 268 Patients with Painful Osteoporotic Vertebral Compression Fracture.

Objective: To evaluate the risk factors of new osteoporotic vertebral compression fractures (OVCFs) after percutaneous vertebroplasty (PVP).

Methods: From January 2016 to November 2019, patients suffering from OVCFs were retrospectively reviewed. The independent influence factors for new OVCFs after PVP were assessed, from following variables: age, sex, body mass index, bone mineral density (BMD), history of alcoholism, smoking, hypertension, diabetes, glucocorticoid use, and prior vertebral fractures, the number of initial fractures, mean cement volume, method of puncture, D-type of cement leakage, and regular antiosteoporosis treatment.

Applications of gastric peroral endoscopic myotomy in the treatment of upper gastrointestinal tract disease.

Gastric peroral endoscopic myotomy (G-POME) is an emerging minimally invasive endoscopic technique involving the establishment of a submucosal tunnel around the pyloric sphincter. In 2013, Khashab used G-POME for the first time in the treatment of gastroparesis with enhanced therapeutic efficacy, providing a new direction for the treatment of gastroparesis. With the recent and rapid development of G-POME therapy technology, progress has been made in the treatment of gastroparesis and other upper digestive tract diseases, such as congenital hypertrophic pyloric stenosis and gastric sleeve stricture, with G-POME.

The novel protein complex FAPα/ITGA5 is involved in the bone destruction of apical periodontitis.

The bacteria that invade the periapical tissue of teeth can directly damage tissue cells such as periapical fibroblasts, leading to an inflammatory response in the periapical tissue and ultimately resulting in bone destruction. We investigated the role of fibroblast activation protein α (FAPα) and integrin α5 (ITGA5) in periapical bone destruction. This study found that FAPα and ITGA5 were highly expressed in human tissues from patients with chronic apical periodontitis.

Neoadjuvant Chemotherapy or Adjuvant Chemotherapy for Esophageal Squamous Cell Carcinoma.

Background: Chemotherapy and chemoradiation have become essential adjuncts to improve the survival of patients with resectable esophageal squamous cell carcinoma (ESCC) in the perioperative period. Although preoperative treatment plus surgery is commonly used, controversy remains regarding the optimal treatment strategy for patients with locally advanced ESCC.

Methods: A retrospective review of clinical stage II and III ESCC patients who underwent esophagectomy at Henan Cancer Hospital between October 2014 and October 2017 was performed.

Importance of accurate diagnosis of congenital agenesis of the gallbladder from atypical gallbladder stone presentations: A case report.

Background: Congenital agenesis of the gallbladder (CAGB) is a rare condition often misdiagnosed as cholecystolithiasis, leading to unnecessary surgeries. Accurate diagnosis and surgical exploration are crucial in patients with suspected CAGB or atypical gallbladder stone symptoms. Preoperative imaging, such as magnetic resonance cholangiopancreatography (MRCP), plays a vital role in confirming the diagnosis.

A multicenter randomized, controlled clinical trial of adjuvant sintilimab for esophageal squamous cell carcinoma.

No adjuvant treatment has been established for patients who remain at high risk of recurrence and incidental pathologic lymph node metastasis for esophageal squamous cell carcinoma (ESCC). In this open-label, multicenter, phase III, randomized controlled trial, ESCC patients who did not achieve pathologic complete response after neoadjuvant chemotherapy plus surgery and clinical T1-2 N0 patients with incidental pathologic lymph node metastasis following initial surgery were randomized at a 2:1 ratio to receive either a sintilimab regimen or observational management (NCT05495152). The primary end point was disease-free survival for all randomized patients.

The prognostic impact of tumor length on pathological stage IA-IC esophageal adenocarcinoma.

This study was completed to evaluate the relationship between tumor length and the prognosis of patients with pathological stage IA-IC esophageal adenocarcinoma (EAC). Patients were identified from the Surveillance, Epidemiology, and End Results Program database (United States, 2006-2015). X-tile software and ROC analysis were mainly used to explore the best threshold of tumor length for dividing patients into different groups, and then propensity score matching (PSM) was used to balance other variables between groups.

Patterns and Influence of Lymph Nodal Metastases After Neoadjuvant Chemotherapy and Surgery for Thoracic Esophageal Squamous Cell Carcinoma.

Purpose: The purpose of this retrospective study was to define the pattern of lymph nodal metastases in patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemotherapy (NCT) followed by esophagectomy and to evaluate its influence on prognosis.

Methods: A total of 398 patients with clinical stage T3N0 or T1-3N+ ESCC who underwent NCT and radical esophagectomy with two-field lymphadenectomy were included. The distribution and frequency of metastases were counted separately for each lymph node station.

Artificial Intelligence in Inflammatory Bowel Disease Endoscopy: Advanced Development and New Horizons.

Inflammatory bowel disease (IBD) is a complex chronic immune disease with two subtypes: Crohn's disease and ulcerative colitis. Considering the differences in pathogenesis, etiology, clinical presentation, and response to therapy among patients, gastroenterologists mainly rely on endoscopy to diagnose and treat IBD during clinical practice. However, as exemplified by the increasingly comprehensive ulcerative colitis endoscopic scoring system, the endoscopic diagnosis, evaluation, and treatment of IBD still rely on the subjective manipulation and judgment of endoscopists.

Initial experience with modified en bloc robot-assisted minimally invasive oesophagectomy for thoracic oesophageal squamous cell carcinoma.

Background: The feasibility and safety of en bloc robot-assisted minimally invasive oesophagectomy (RAMIE) need to be verified.

Methods: Forty-seven patients who received conventional RAMIE and 31 who received modified en bloc RAMIE at Henan Cancer Hospital were included in the study cohort. We compared the perioperative outcomes of conventional RAMIE and modified en bloc RAMIE.

Genetic Diversity Evaluation and Conservation of Topmouth Culter () Germplasm in Five River Basins in China.

To study the genetic diversity of () populations, we analyzed the genetic diversity of five populations from Songhua Lake (SH), Huaihe River (HH), Changjiang River (CJ), Taihu Lake (TH), and Gehu Lake (GH) based on mitochondrial gene sequences. The results showed that the average contents of bases T, C, A, and G in the 526 bp gene sequence were 25.3%, 18.

Survival impact of the number of lymph nodes dissection in patients receiving neoadjuvant chemotherapy for esophageal squamous cell carcinoma.

This study aimed to investigate the survival impact of the number of lymph nodes dissection (LND) in patients receiving neoadjuvant chemotherapy (NCT) for esophageal squamous cell carcinoma (ESCC). We retrospectively analyzed the clinical pathological data and survival of 407 ESCC patients who underwent esophagectomy after NCT between January 2015 and December 2016. The relationship between the number of LNDs and 5-year overall survival (OS) or disease-free survival (DFS) was plotted by using restricted cubic spline analysis.

Perioperative Outcomes and Learning Curve of Robot-Assisted McKeown Esophagectomy.

Background: This study aimed to evaluate the perioperative outcomes of patients undergoing robot-assisted McKeown esophagectomy (RAME) and the learning curves of surgeons performing RAME at a single center.

Methods: Perioperative outcomes of RAME and video-assisted McKeown esophagectomy (VAME) were compared after eliminating confounding factors by propensity score matching (PSM). The cumulative sum (CUSUM) method was used to evaluate the learning curves of RAME for a single surgical team.

Chemometrics-enhanced high-performance liquid chromatography-diode array detection strategy to quantify protoberberine alkaloids in varying Coptidis Rhizoma-related medicines.

Quantitation of protoberberine alkaloids is an essential guarantee for efficacy control and medication safety of Coptidis Rhizoma (CR) related medicines. Traditional univariate chromatography faced challenges with co-elution, unknown interferences, and retention time shift when analyzing isomeric analytes in varying sample matrices. We presented a chemometrics-enhanced high-performance liquid chromatography-diode array detection (HPLC-DAD) strategy for simultaneous quantification of six protoberberine alkaloids and processed multi-channels chromatographic-spectral data with four second-order calibration algorithms.

Intelligent analysis of excitation-emission matrix fluorescence fingerprint to identify and quantify adulteration in camellia oil based on machine learning.

Camellia oil (CAO) is a premium edible vegetable oil with medical value and biological activity, but it is susceptible to adulteration. Therefore, the demand for intelligent analysis to decipher the category and proportion of adulterated oil in CAO was the main driver of this work. Excitation-emission matrix fluorescence (EEMF) spectra of 933 vegetable oil samples were characterized by a chemometric method to obtain chemically meaningful information.
