Objective:
To investigate the incidence and risk factors of open gingival embrasures (OGEs) in the incisor region after treatment with clear aligners in adult non-extraction patients and provide a reference for preventing the occurrence of an open gingival wedge gap in the incisal area after orthodontic treatment.
Methods:
This study has been reviewed and approved by the institutional medical ethics committee, and informed consent was obtained from the patients. A total of 125 adult patients with malocclusion who completed clear aligner treatment at Hefei Stomatological Hospital from September 2022 to December 2024 were selected as the study subjects. Based on the presence or absence of OGEs in the incisor region observed in frontal intraoral photographs taken immediately after treatment completion, the patients were divided into a normal group and an OGE group. Clinical data, including intraoral photographs, digital models, and cone-beam computed tomography before and after treatment, were analyzed. Measurements such as incisor overlap and rotation, crown morphology, number of attachments, and interproximal enamel reduction (IPR) were recorded and analyzed.
Results:
The incidence of OGEs between the maxillary and mandibular central incisors after clear aligner treatment in adult patients was 28.8% and 39.2%, respectively. No statistically significant differences were observed between the normal and OGE groups in terms of sex, Angle's classification, gingival biotype, overbite, overjet, IPR amount, age, treatment duration, tooth axis angulation, or horizontal movement distance of mandibular central incisors before and after treatment (P 0.05). However, significant differences were found in the number of attachments, anteroposterior distance between mesial incisal angles, distance from the interproximal contact point (ICP) to the alveolar bone crest (ABC) (ICP-ABC), horizontal distance between mesial cementoenamel junction (CEJ) of two adjacent central incisors (CEJ-CEJ) and labial alveolar bone thickness (P 0.05). IPR amount and mandibular incisor intrusion were significantly associated with the severity of OGEs (P 0.05). Regression analysis revealed that the number of attachments, anteroposterior distance between mesial incisal angles, ICP-ABC distance, and CEJ-CEJ horizontal distance were significantly correlated with the occurrence of OGEs.
Conclusion
The incidence of open gingival embrasures in the mandibular central incisor region is relatively high among adult patients treated with clear aligners. The number of attachments (n = 2), the anteroposterior distance between the mesio-incisal angles, the distance from the tooth contact point to the alveolar bone crest, and the horizontal distance between adjacent cementoenamel junctions have been identified as risk factors for the development of open gingival embrasures upon completion of orthodontic treatment.

With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

ObjectiveTo explore the potential mechanism of Changji'an Formula (肠激安方) on intestinal permeability for rats with diarrhea-predominant irritable bowel syndrome (IBS-D) of liver depression and spleen deficiency syndrome by the microRNA-29b-3p (miR-29b-3p)/tumor necrosis factor receptor-associated factor 3 (TRAF3)/nuclear factor-κB (NF-κB)/myosin light chain kinase (MLCK) axis. MethodsTwenty-four 1-day-old male Sprague-Dawley (SD) suckling rats were selected, and the IBS-D rat model of liver depression and spleen deficiency syndrome was established via a three-factor method,i.e. maternal separation plus acetic acid stimulation and restraint stress, for 6 consecutive weeks. After successful modeling, the rats were randomly divided into a model group, pinaverium bromide group, low-dose and high-dose Changji'an Formula groups, with 6 rats in each group. Another 6 age-matched non-modeled SD rats were included as the control group. The low-dose and high-dose Changji'an Formula groups were given intragastric administration of Changji'an Formula solution at doses of 16.74 g/(kg·d) and 33.48 g/(kg·d), respectively; the pinaverium bromide group received intragastric administration of pinaverium bromide tablets at 0.018 g/(kg·d); and the control group was given distilled water at 10 ml/(kg·d) via intragastric gavage. The intervention was conducted once daily for 14 consecutive days. After the gavage treatment, the fecal water content of rats in each group was measured. Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of intestinal permeability indicators, including D-lactic acid (D-LA), diamine oxidase (DAO), and lipopolysaccharide (LPS). Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to determine the mRNA expression levels of miR-29b-3p, TRAF3, tumor necrosis factor-α (TNF-α), p65, p50, and MLCK in colonic tissues. Western Blot analysis was employed to detect the protein expression levels of TRAF3, TNF-α, p65, phosphorylated p65 (p-p65), MLCK, myosin light chain (MLC), phosphorylated MLC (p-MLC), and tight junction proteins including junctional adhesion molecule-A (JAM-A), Occludin, and Claudin-1 in colonic tissues. ResultsCompared with the control group, the model group exhibited significantly increased fecal water content and serum levels of D-LA, DAO, and LPS, along with decreased protein expression levels of JAM-A, Occludin, and Claudin-1 in colonic tissues (P<0.05 or P<0.01). Additionally, in the model group, the mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK in colonic tissues were up-regulated, while the mRNA and protein expression levels of TRAF3 were down-regulated; the protein levels of TNF-α and MLCK, as well as the ratios of p-p65/p65 and p-MLC/MLC, significantly elevated (P<0.01). Compared with the model group, all treatment groups showed reduced fecal water content and serum levels of D-LA, DAO, and LPS, along with down-regulated mRNA expression levels of miR-29b-3p, TNF-α, p65, p50, and MLCK, and up-regulated TRAF3 mRNA expression in colonic tissues. Moreover, the pinaverium bromide group and high-dose Changji'an Formula group presented increased protein levels of Occludin, Claudin-1, and TRAF3, as well as decreased protein levels of TNF-α and MLCK, and reduced ratios of p-p65/p65 and p-MLC/MLC in colonic tissues (P<0.05 or P<0.01). Compared with the low-dose Changji'an Formula group, the high-dose group had lower fecal water content and serum levels of DAO and LPS (P<0.01). In comparison with the pinaverium bromide group, the high-dose Changji'an Formula group showed a significant decrease in serum DAO level (P<0.01). ConclusionsChangji'an Formula can reduce intestinal permeability and restore intestinal barrier function in IBS-D rats of liver depression and spleen deficiency syndrome by regulating the miR-29b-3p/TRAF3/NF-κB/MLCK axis.

ObjectiveTo explore the microbiological characteristics of Staphylococcus epidermidis with hemolytic phenotype (SEHP). MethodsHemolytic phenotype was detected using the three-point inoculation method, involving a total of 5 strains of SEHP and 5 strains of Staphylococcus epidermidis with non-hemolytic phenotype (SENHP) . Bacterial species were identified using the Microflex LT MALDI-TOF mass spectrometer, and a phylogenetic tree was constructed through 16S rRNA sequence alignment. Growth curves were monitored through the microcultivation assay. Biofilm formation ability was assessed by microplate crystal violet staining. Red blood cell toxicity was detected using the microplate method. Antimicrobial susceptibility testing of SEHP and SENHP against commonly used antibiotics was performed using a VITEK 2 GP639 test kit. Antagonistic effects of SEHP and SENHP against Staphylococcus aureus and Corynebacterium striatum were evaluated by the Oxford cup inhibition assay. ResultsCompared with SENHP, SEHP exhibited a marked decrease in growth rate during the late logarithmic phase, accompanied by significant hemolytic toxicity. Additionally, it showed lower resistance rates to levofloxacin and moxifloxacin, and could antagonize Staphylococcus aureus and Corynebacterium striatum. ConclusionThe microbiological characteristics of SEHP differ from those of SENHP in that SEHP demonstrates antagonistic effects against S. aureus and C. striatum.

Erchentang is a classic formula widely used by medical practitioners throughout history. In this paper,ancient and modern literature of Erchentang were collected, and bibliometrics was employed to analyze its historic evolution,prescription meaning,herbs origin, processing method,preparation methods, and clinical application. A total of 84 pieces of data were collected, and 58 pieces of data involving 53 ancient medical Chinese books were screened, sorted, and processed. Combined with research of modern scholars,the research has found that the Erchentang originated from the Taiping Huimin Huiye Shijie Fang compiled by the Imperial Medical Bureau of the Song Dynasty. The basic information about the origin of the drugs is quite clear. Pinelliae rhizoma in the formula is the dried tuber of Pinellia ternata. Citri exocarpium rubrum is the dried mature peel of Citrus reticulata and its cultivated varieties, with the inner white membrane removed. Poria is the whitest dry sclerotia of Poria cocos; Glycyrrhizae radix et rhizoma is the dried root and rhizome of the Glycyrrhiza uralensis. The dosage is 5.70 g Pinelliae rhizome and Citri exocarpium rubrum, 3.43 g Poria, and 1.69 g Glycyrrhizae radix et rhizoma praeparata cum melle. During the decoction process, the above-mentioned herbs should be chopped, with 300 mL water, 7 g ginger in thick slices, and 2 g Mume fructus added, and it was then simmered together to 180 mL. After removing the medicinal residue, it can be taken warmly. Erchentang has the effect of drying dampness and resolving phlegm, regulating Qi and harmonizing the middle. It can be used in treating the syndrome of phlegm and dampness,as well as symptoms such as frequent cough,white phlegm,fullness in chest and diaphragm,nausea and vomiting,limb drowsiness,anorexia,dizziness,palpitations,white and greasy tongue coating, and slippery pulse. The above results provide reference for future research and development of Erchentang.

OBJECTIVE To establish a “BRAND” pharmaceutical care model for advanced non-small cell lung cancer (NSCLC) patients with positive driver genes, providing theoretical and practical references for the clinical implementation of precise and individualized oncology pharmaceutical care. METHODS One hundred patients admitted to the department of pulmonary and critical care medicine in our hospital from January 2023 to May 2024 were collected meeting the inclusion and exclusion criteria. Patients were randomly divided into control group and intervention group, with 50 patients in each group. The control group received routine pharmaceutical care, while the intervention group received pharmaceutical care under the “BRAND” model (collecting patients’ basic information, reviewing disease treatment-related information, conducting precise medication assessments, formulating individualized pharmaceutical care plans for the next steps, and implementing medication guidance and follow-up management). The study was conducted in a 3-week cycle for a total of 4 cycles. The medication compliance, quality of life, laboratory test indicators, incidence of drug-related adverse events and satisfaction of patients in both groups were compared before and after the intervention to evaluate the effects. RESULTS After 12 weeks of intervention, compared with the control group, the medication compliance, cognitive function, social function and satisfaction of patients in the intervention group were improved significantly ( P <0.05); the severity of fatigue and constipation and the incidence of drug-related adverse events were significantly reduced ( P <0.05), and there was no statistically significant difference in laboratory test indicators ( P >0.05). CONCLUSIONS The “BRAND” pharmaceutical care model can effectively improve the medication compliance of patients with advanced NSCLC with positive driver genes and improve their quality of life. This study can provide a feasible path for clinical pharmacists to carry out standardized and high-quality pharmaceutical care.

OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors (DTIs) in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital (the Affiliated Hospital of UESTC), a multidisciplinary working group was established. Through literature review and the Delphi method, clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework; systematic searches were conducted in CNKI, Medline, Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment,Development and Evaluation (GRADE) approach, and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations (each with an expert consensus rate exceeding 90%) on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection, dosing ranges, key monitoring points, and safety management strategies for parenteral DTIs in various scenarios, including the perioperative period of ventricular assist device implantation, the perioperative period of cardiac surgery, perioperative patients with lower-extremity atherosclerotic disease, the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome, the perioperative period of carotid artery stenting in patients with carotid stenosis, the perioperative period of patients with right heart thrombosis, and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition, warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus, which is formulated based on the best available evidence, provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Parkinson's disease (PD) is a complex neurodegenerative disease involving multiple systems and neurotransmitters. Due to the high clinical heterogeneity of PD,it is urgent to establish a comprehensive and long-term traditional Chinese medicine (TCM) management model. In this paper,the conceptual framework of full-cycle management of PD is preliminarily constructed:based on the evolution of the pathophysiological mechanisms of protein deposition and neurotransmitter disorder in PD,the three-stage syndrome characteristics of the prodromal stage (predominant healthy Qi with subtle pathogenic factors),the early clinical stage (declining healthy Qi with growing pathogenic factors) and the middle and late stages (overwhelming pathogenic factors with deficient healthy Qi) are longitudinally described. Through the syndrome differentiation of visceral manifestations,the etiology and pathogenesis of PD motor and non-motor symptoms were comprehensively analyzed,while the matching treatment methods and prescriptions were inferred,and the modular scheme of the combining main symptoms,accompanying symptoms and secondary symptoms was proposed. The conceptual gap of TCM regarding motor complications ('variable syndrome') and PD-related hyperpyrexia syndrome ('critical syndrome') was explained. This framework reflects the characteristics of combination of disease and syndrome and overall constant motion,and provides new theories and research ideas for individualized and whole-process management of PD in TCM.
