This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine （TCM） for gastroesophageal reflux disease （GERD）. Studies demonstrate that TCM， based on the "disease-syndrome combination" approach， exhibits multi-target advantages in alleviating symptoms of various GERD subtypes， promoting mucosal repair， regulating emotions， and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy， strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions， promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory， human experience and clinical trial evidence， and optimizing integrated traditional and western medicine models to enhance GERD management.

OBJECTIVES: This study aimed to evaluate the therapeutic effect of 1% povidone-iodine mouthwash combined with scaling and root planing in patients with stage Ⅰ/Ⅱ class A/B periodontitis, and to provide a basis for the clinical application of povidone-iodine mouthwash. METHODS: Seventy-five subjects were included in this trial and randomly divided into three groups. After full-mouth ultrasonic supragingival cleansing, scaling and root planing, the placebo group was treated with sodium chloride injection (NaCl group), the control group was treated with compound chlorhexidine mouthwash (CHX group), and the experimental group was treated with 1% povidone-iodine mouthwash (PVP-I group), and rinsed their mouths for 1 week, respectively. Subjects were tested at 1, 4, and 12 weeks after dosing for clinical indicators, microbial composition of supragingival plaque, gingival crevicular fluid inflammatory marker levels, and patient-reported outcomes. RESULTS: Sixty-three subjects completed the follow-up. After treatment, the clinical indicators, microbial indicators, and inflammatory indicators were all significantly improved (P<0.05). Comparisons among the groups showed that one week after treatment, the bleeding index and plaque index of the CHX group and the PVP-I group were lower than those of the NaCl group, and the plaque index of the CHX group was lower than that of the PVP-I group (P<0.05). There were no statistically significant differences in the other clinical indicators among the groups (P>0.05). Twelve weeks after treatment, the Shannon index of the CHX group was lower than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other microbial indicators among the groups (P>0.05). Twelve weeks after treatment, the interleukin-10 concentration of the CHX group was higher than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other inflammatory indicators among the groups (P>0.05). The PVP-I group had the highest scores in terms of taste and oral odor. There was no obvious staining on the tooth surfaces and mucosa in all three groups. CONCLUSIONS 1% PVP-I mouthwash combined with scaling and root planing can effectively reduce gingival inflammation and dental plaque, improve clinical symptoms in the short term. While its efficacy is not significantly inferior to that of chlorhexidine, PVP-I mouthwash is more acceptable to patients than chlorhexidine.

Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.

Triple-negative breast cancer is therapeutically challenging due to the low expression of tumor markers and 'cold' tumor immunosuppressive microenvironment. Here, we present a dual-targeting peptide-drug conjugate (PDC) for tumor inhibition. Our PDC efficiently and selectively delivers cytotoxic Monomethyl Auristatin E (MMAE) into tumor cells via C-X-C chemokine receptor type 4 (CXCR4) and folate receptor 1 (FOLR1) for synergistic inhibition of growth and metastasis. Our results show that the dual-targeting PDC has potent antitumor activity in cultured human cells and several murine transplanted tumor models without apparent toxicity. The combination of dual-targeting PDC and radiotherapy modulates the tumor immunosuppressive microenvironment by increasing CD8⁺ T cell infiltration and attenuating the proportion of myeloid-derived suppressor and regulatory T cells. Therefore, our dual-targeting PDC represents a promising new strategy for cancer therapy that rebalances the immune system and promotes tumor regression.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Objective This study aimed to investigate the temporal and spatial changes in the expression of perios-tin during periodontal inflammation in mice.Methods A periodontitis model was constructed using silk thread ligation.Mice were randomly divided into five groups in-cluding control group,4-day ligation group,7-day liga-tion group,14-day ligation group,and self-healing group(thread removal for 14 days after 14-day ligation).Mi-cro-CT and histological staining were performed to char-acterize the dynamic changes in the mouse periodontal tissue in each group.RNAscope and immunohistochemical staining were used to analyze the pattern of changes in peri-ostin at various stages of periodontitis.The cell experiment was divided into three groups:control group,lipopolysac-charide(LPS)stimulation group(treated with LPS for 12 h),and LPS stimulation removal group(treated with LPS for 3 h followed by incubation with medium for 9 h).Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect the expression of periostin,transforming growth factor-β1(TGF-β1),and matrix metalloproteinase 2(MMP2).Results Significant alveolar bone resorption was observed 7 days after ligation.With increasing duration of ligation,the damage to the mouse periodontal tissue was aggravated,which manifested as increased osteoclasts,widen-ing of the periodontal membrane space,and decreased alveolar bone height.Some degree of periodontal tissue repair was observed in the self-healing group.Periostin expression decreased at 4 and 7 days compared with the control group and increased at 14 days compared with 4 and 7 days.A significant recovery was found in the self-healing group.The qRT-PCR results showed that the expression of periostin and TGF-β1 in the LPS stimulation group decreased compared with that in the control group but significantly recovered in the LPS removal group.Conclusion Periostin expression in the PDL of mice showed a downward and upward trend with inflammation progression.The significant recovery of periostin expression after removing inflammatory stimuli may be related to TGF-β1,which is crucial to maintain the in-tegrity of the PDL.

Objective:To explore the current status of rumination in inpatients with metastatic prostate cancer (mPCa) under the disease coping mechanism, and analyzing its influencing factors.Methods:From March 2021 to December 2022, 267 mPCa inpatients at the Tenth People's Hospital of Tongji University were selected as the study subject using convenience sampling. The survey was conducted using the General Information Questionnaire, Chinese Version of Event Relate Rumination Inventory (C-ERI), Medical Coping Modes Questionnaire (MCMQ), International Prostate Symptom Score (IPSS), and Social Support Revalued Scale (SSRS), and the factors influencing the rumination in patients were analyzed.Results:This study collected 260 valid questionnaires, with an effective response rate of 97.4% (260/267). The total score of rumination in 260 mPCa patients was (31.08±6.46), with invasive rumination and purposeful rumination scores of (14.13±4.44) and (16.95±4.55), respectively. The initial prostate-specific antigen index, confrontation medical coping modes were the influencing factors of invasive rumination in mPCa patients ( P<0.05). The initial prostate-specific antigen index, course of disease, social support, and confrontation medical coping style were the influencing factors of purposeful rumination in mPCa patients ( P<0.05) . Conclusions:The rumination of mPCa patients is above the medium level, and is influenced by multiple factors under the disease coping mechanism. Clinical medical and nursing staff should combine the clinical situation and characteristics of mPCa patients, provide personalized interventions as early as possible, and assist patients in improving their positive cognitive processing abilities.
