Background: Trastuzumab constitutes the fundamental component of initial therapy for patients with advanced human epidermal growth factor receptor 2 (HER-2)-positive gastric cancer (GC). However, the efficacy of this treatment is hindered by substantial challenges associated with both primary and acquired drug resistance. While S-phase kinase associated protein 2 (Skp2) overexpression has been implicated in the malignant progression of GC, its role in regulating trastuzumab resistance in this context remains uncertain.

Current studies have shown that ARNTL, an important clock gene, plays an anticancer role and is downregulated in certain types of cancer. However, the biological functions and mechanisms of ARNTL in tumors remain largely unknown. This study aimed to elucidate how ARNTL-induced autophagy impacts the biological properties of tongue squamous cell carcinoma (TSCC) cells and the mechanisms by which ARNTL expression activates autophagy.

Background And Objectives: Low-intensity pulsed ultrasound (LIPUS) promotes differentiation and regulates biological functions of various stem cells, but its effect on the endothelial differentiation of periodontal ligament stem cells (PDLSCs) is unclear. This study investigated the effect of LIPUS on endothelial differentiation and angiogenesis in PDLSCs and the role of the mechanically sensitive ion channel in this process.

Methods And Results: PDLSCs obtained from healthy people were used for endothelial induction, and 10 g/ml lipopolysaccharide (LPS) was used to simulate the inflammatory state.

BACKGROUND This study aimed to evaluate the desensitizing effect of toothpaste containing the active ingredients of an extract of Galla chinensis, both in vitro and in patients with dentin hypersensitivity. MATERIAL AND METHODS Ninety-eight patients with dentin hypersensitivity were divided into two study groups and given toothpaste containing either the active ingredients of Galla chinensis extract and sodium fluoride, or a control toothpaste containing only sodium fluoride. Assessments included the tactile stimulation test and the Schiff cold air sensitivity scale, which were conducted at the baseline examination and after 4 and 8 weeks of dental brushing.

Objective: To systematically evaluate the repairing effect of stem cells on facial nerve defects.

Methods: Articles regarding the regenerating effect of stem cells on facial nerves in animals were collected from the databases of Pubmed, Cochrane Library, Web of Science, Embase, Scopus, and CBM. Two professionals independently completed the article screening, data extraction, and bias risk assessment.

Article Synopsis
  • - The study aimed to assess oral health knowledge, attitudes, and behaviors of 12-15-year-olds in Chongqing to identify areas for preventive measures.
  • - Researchers collected and analyzed data from 3,902 students, revealing that only 39.7% had good brushing habits, with an average oral health knowledge accuracy of 58.9% and a positive attitude rate of 88.6%.
  • - Results indicated significant gaps in oral health practices, particularly in rural areas, highlighting the need for improved oral health education for middle school students.

Objective: The aim of this study is to survey the need, the utilization, and the influencing factors of dental services for children in selected areas in Chongqing province by investigating their oral health status. The survey will provide references for preventive oral health care in targeted Chongqing areas, which may improve the level of oral health among pre-school children.

Methods: Random cluster sampling was utilized according to standards of the Fourth National Oral Health Epidemiological sampling survey, and 1 300 children between the ages of three and four years old from 24 kindergartens in 12 subdistricts of three areas in Chongqing were interviewed for free dental checkups and to participate in the survey.

Although many researchers have studied on the association between vitamin D receptor (VDR) BsmI polymorphism and periodontitis, this association remains elusive. To further assess the effects of VDR BsmI polymorphism on the risk of periodontitis, a meta-analysis was performed in a single ethnic group. We searched PubMed and Chinese databases for relevant studies till April 2017.

Article Synopsis
  • The study explored the importance of detecting micrometastasis in sentinel lymph nodes (SLN) of patients with early cervical cancer by analyzing lymph nodes collected during surgery.
  • A total of 268 lymph nodes were examined, revealing a high sensitivity (66.7%) and accuracy (96.4%) for SLN detection, but also a significant false negative rate (16.7%) for micrometastasis identified by advanced PCR methods.
  • The findings indicated that micrometastasis is prevalent even in lymph nodes that appear pathologically negative, with a crucial relationship between SLN micrometastasis and the presence of more extensive lymph node involvement.

Objective: To investigate the feasibility of unilateral or bilateral nerve-sparing radical hysterectomy and evaluate the recovery of bladder and bowel function postoperatively.

Methods: From August 2008 to October 2009, sixty-one patients with cervical cancer stage Ib1 to IIa underwent radical hysterectomy (33 cases) and nerve-sparing radical hysterectomy (28 cases). Unilateral nerve-sparing radical hysterectomy was performed in 10 patients, and bilateral nerve-sparing radical hysterectomy (BNS) was performed in 18 patients.
