This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Glaucoma is one of the most common optic neuropathies, featuring progressive retinal ganglion cell damage and visual field loss (Tham et al., 2014; Xu et al., 2020). Currently, the only effective treatment for this condition is the reduction of intraocular pressure (IOP) (Palmberg, 2001; Heijl et al., 2002). Canaloplasty is a proven bleb-independent surgery with good efficacy and safety profiles in primary open-angle glaucoma (POAG) (Gołaszewska et al., 2021). However, early transient postoperative IOP elevation has been reported in up to 30% of cases (Riva et al., 2019), similar to that commonly observed in other internal drainage glaucoma surgeries such as implantation using iStent (0%-21.0%), CyPass (10.8%), and Hydrus (4.8%-6.5%) (Lavia et al., 2017). This complication may be a predictor of poor reserve in the outflow system and is potentially associated with surgical failure. Nonetheless, the exact pathophysiology of glaucoma remains unknown, and studies clarifying the risk factors for postoperative IOP elevation have been scarce.

Ischemic stroke is one of the most important causes of death and disability in humans,but the effective methods for treating brain injury after stroke are quite limited.Sphingosine 1-phosphate (S1P) is a pleiotropic lipid.There is certain interdependence between its metabolism and regulation and the molecular mechanisms involved in important biological events following cerebral ischemia.Membrane lipid therapy with S1P as the core may be an effective neuroprotective strategy of ischemic stroke.

Objective: To explore the expression of long noncoding RNA (lncRNA) HOXA11-AS in esophageal squamous cell carcinoma tissues and the relationship of HOXA11-AS level with clinical outcomes. Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression level of HOXA11-AS in cell lines HET-1A, EC9706, EC109, and in tumor tissue and paired adjacent tissue samples from 73 ESCC patients who received surgical resection.The correlations of the expression level of HOXA11-AS with clinicopathological features and prognosis were also analyzed. Results: The relative expression levels of HOXA11-AS in tumor tissue and paired adjacent tissue were 0.832±0.387 and 2.486±1.087, respectively, with significant difference (P<0.001). The expression of HOXA11-AS was upregulated in 63.0%(46/73)ESCC tissues. The relative expression levels of HOXA11-AS in HET-1A, EC-9706 and EC-109 cells were 1.000, 23.553±3.221 and 17.217±1.968, respectively. The expression level of HOXA11-AS was upregulated in ESCC cell lines (P<0.001). High expression level of HOXA11-AS was correlated with histological grade and lymph node metastasis of ESCC patients (P<0.05). However, it was not associated with the age, gender, depth of infiltration and TNM staging (P>0.05). The median overall survival (OS) and median disease-free survival (DFS) of patients with low HOXA11-AS expression were 43 months and 42 months, respectively, significantly longer than 37 months and 28 months of patients with HOXA11-AS high expression (P<0.05). Cox model multivariate analysis showed that the expression of HOXA11-AS and lymph node metastasis were independent factors of poor prognosis of ESCC patients. Conclusions The expression of HOXA11-AS is upregulated in esophageal cancer cell lines and tissues. High expression of HOXA11-AS is associated with poor prognosis of ESCC patients.Therefore, LncRNA HOXA11-AS may serve as a predictive marker of postoperative ESCC patients.

Objective: To analyze the expression and prognostic significance of esophageal squamous cell carcinoma associated long non-coding RNA-1 (ESCCAL-1) in esophageal squamous cell carcinoma (ESCC) tissues. Methods: From August 2011 to May 2013, 73 patients with ESCC, who received radical resection in The First Affiliated Hospital of Zhengzhou University and Henan Cancer Hospital, were enrolled. The expressions of ESCCAL-1 in esophageal tumor tissues and corresponding adjacent non-tumor tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). T test, chi square test and multivariate analysis were performed for statistical analysis. Results: The expression of ESCCAL-1 was 28.03±9.37 in esophageal tumor tissues of patients with ESCC, which was higher than that in corresponding adjacent normal tissues (11.39±4.15), and the difference was statistically significant (t=2.964, P<0.01). However there were no statistically significant differences in the expressions of ESCCAL-1 among the patients with different age, gender, histological grade, classification of Union for International Cancer Control (UICC), T stage or lymph nodes metastasis (all P>0.05). The median disease-free survival (DFS) time and overall survival (OS) time of patients with low ESCCAL-1 expression were 39 months and 42 months, respectively, which were longer than those of patients with high ESCCAL-1 expression (30 months and 37 months), and the differences were statistically significant (χ²=9.049, P=0.003; χ²=10.165, P=0.001). The results of multivariate analysis showed that ESCCAL-1 expression was the independent risk factor of DFS and OS (high risk (HR)=2.45, 95% confidence interval (CI) 1.22 to 4.93, P=0.012; HR=2.29, 95%CI 1.14 to 4.59, P=0.019). Conclusions ESCCAL-1 may be involved the genesis and development of ESCC. The expression of ESCCAL-1 in esophageal tumor tissues may be a prognostic parameter for patients with ESCC receiving radical resection.

Objective: To investigate the molecular mechanism of colistin resistance in Klebsiella pneumoniae (K.pneumoniae). Methods: Three clinical isolates of colistin-resistant K. pneumoniae (FK1149, FK1920 and FK1934) and three colistin-resistant mutants (FK660R, FK713R and FK729R) were investigated. Resistance genes of pmrAB, phoPQ, mgrB, crrAB, mcr-1 and mcr-2 were detected by PCR and then analyzed by sequencing. PROVEAN platform was used to predict changes in the biological functions of proteins related to drug resistance. Expression of pmrH, pmrC, mgrB and phoP genes was measured using quantitative real-time PCR. LPS silver staining and conjugation assay were performed to analyze the three clinical colistin-resistant isolates. Results: Amino acid substitutions in PmrA (G53V), PmrB (T157P, R256G), MgrB (F44C) and CrrB (E189K) were detected. ISkpn14 and IS5-like insertion sequences were detected in FK713R and FK729R, respectively. FK1149, FK1920 and FK1934 were negative for mcr genes. Compared with the wild-type strain, expression of pmrH and pmrC genes at the transcriptional level was increased in all investigated isolates. Changes in the expression of phoP and mgrB genes were also observed. A partial deletion of LPS was identified in FK1149. Conclusion LPS modification induced by inactivation of PmrAB or MgrB is the main molecular mechanism of colistin resistance in K. pneumoniae isolates in this study. Mutations in PmrA (G53V), MgrB (F44C) and CrrB (E189K) that might be related to colistin resistance are detected for the first time in clinical isolates of K. pneumoniae.

Objective To investigate the mitochondrial energy metabolism in D-galactoseinduced cell ageing model.Methods MRC-5 cells were cultivated for 72 hours in a medium containing 55 mmol/L D-galactose.The analysis of cell proliferation capacity by CCK8 method,β-galactosidase staining and detection of p21 protein expression level were performed for identifying cell senescence.The cell oxidation-reduction state was evaluated by an analysis of cellular ROS levels,SOD activity,MDA content and oxidative damage level of mitochondrial DNA(mtDNA).For purpose of detecting mitochondrial function and its impairment,mitochondrial morphology was observed by electron microscope,mitochondrial quantity was analyzed by flow cytometry,mitochondrial membrane potential(△Ψm) was measured by JC-1 staining,and ATP content was analyzed by HPLC,and mitochondrial oxygen consumption rate was detected by Seahorse cell energy metabolism detection system.Results The decreased MRC-5 cell proliferation,up-expression of p21 protein,increased β-galactosidase activity were observed in D-Gal-treated cells,which indicated the cell premature senescence.When treated with D-Gal,the significantly increased ROS and MDA level,decreased SOD activity and increased oxidized mtDNA proved that the cells kept higher oxidative stress.D-Gal induced-mitochondrial impairment was evidenced by the dimming of mitochondrial cristae and double membrane structure,decrease of transmembrane potential and ATP synthesis,and decrease of its oxygen consumption rate(OCR).Conclusions The 55 mmol/L D-Gal causes an impairment of mitochondrial structure and a decrease of function of energy metabolism,which is associated with cellular senescence induced by D-Gal.
