Objective: To analyze the status and trends of the disease burden of periodontal disease among women of reproductive age (15-49 years) in China from 1990 to 2021, and to provide a reference for the development of periodontal disease prevention and control strategies for women of reproductive age. Methods: Using the global burden of disease (GBD) data from 1990 to 2021, this study investigated the periodontal disease burden among women of reproductive age, including prevalence, incidence, disability-adjusted life years (DALYs), DALY rates, and their corresponding standardized indicators. Joinpoint 5.2.0.0 software was used for time trend analysis of DALYs, age-specific DALY rates, and annual average percentage change (AAPC) values. A log-linear regression model was used to test trends for DALYs and DALY rates. Results: Compared with 1990, the prevalence and incidence of periodontal disease among Chinese women in 2021 increased by 45.67% (per 100,000 people) and 29.29% (per 100,000 people), respectively. The distribution of periodontal disease among women (15-49 years) showed a continuous and rapid upward trend, with the growth rate increasing rapidly with age. The number of cases increased the fastest in the 45-49 age group, and the prevalence increased the fastest in the 35-44 age group. The incidence of periodontal disease continued to rise with age, with the fastest increase in the 35-44 age group among women of reproductive age. The Joinpoint regression model results showed that periodontal disease led to an expanding trend in the disease burden among women of reproductive age in China, with an AAPC of DALYs = 1.20% and an AAPC of DALY rate = 1.25% (P<0.001). Conclusion The periodontal disease burden among Chinese women aged 15-49 years showed a gradually increasing trend from 1990 to 2021.

This case report presents a 16-year-old male patient with deficiency of adenosine deaminase 2(DADA2). The patient had a history of Raynaud′s phenomenon with digital ulcers since childhood. As the disease progressed, the patient developed retinal vasculitis, intracranial hemorrhage, skin necrosis, severe malnutrition, refractory hypertension, and gastrointestinal bleeding. Genetic testing revealed compound heterozygous mutations in the ADA2 gene (paternal c.1072G > A pathogenic mutation + maternal c.1065C > A variant of unknown clinical significance). ADA2 enzyme activity was significantly reduced (0.1 U/L). A multidisciplinary treatment team developed an individualized plan to address key issues, including nutritional support, blood pressure control, rehabilitation, pain management, and balancing anticoagulation/bleeding risks. After systematic intervention, the patient′s condition showed partial improvement. This case reveals clinical challenges such as anticoagulation decisions and nutritional support of DADA2. It also emphasizes the importance of early molecular diagnosis, tumor necrosis factor-α inhibitor targeted therapy, and multidisciplinary collaboration in management, underlining the core value of precision medicine in rare disease management.

Studies have suggested that the nucleus accumbens (NAc) is implicated in the pathophysiology of major depression; however, the regulatory strategy that targets the NAc to achieve an exclusive and outstanding anti-depression benefit has not been elucidated. Here, we identified a specific reduction of cyclic adenosine monophosphate (cAMP) in the subset of dopamine D1 receptor medium spiny neurons (D1-MSNs) in the NAc that promoted stress susceptibility, while the stimulation of cAMP production in NAc D1-MSNs efficiently rescued depression-like behaviors. Ketamine treatment enhanced cAMP both in D1-MSNs and dopamine D2 receptor medium spiny neurons (D2-MSNs) of depressed mice, however, the rapid antidepressant effect of ketamine solely depended on elevating cAMP in NAc D1-MSNs. We discovered that a higher dose of crocin markedly increased cAMP in the NAc and consistently relieved depression 24 h after oral administration, but not a lower dose. The fast onset property of crocin was verified through multicenter studies. Moreover, crocin specifically targeted at D1-MSN cAMP signaling in the NAc to relieve depression and had no effect on D2-MSN. These findings characterize a new strategy to achieve an exclusive and outstanding anti-depression benefit by elevating cAMP in D1-MSNs in the NAc, and provide a potential rapid antidepressant drug candidate, crocin.

Objective To investigate the feasibility and early efficacy of transapical transcatheter aortic valve replacement (TAVR) combined with transcatheter mitral valve edge-to-edge repair (TEER) in patients with high-risk aortic valve lesions combined with severe mitral regurgitation. Methods The clinical data of patients who underwent "one-stop" transapical TAVR+TEER in our hospital from August 2022 to October 2023 were retrospectively analyzed. Results Five patients were collected, including 3 males and 2 females with a mean age of 66.6±1.8 years. Four patients had aortic valve insufficiency combined with mitral regurgitation and one had aortic valve stenosis and insufficiency combined with mitral regurgitation. All patients successfully completed transapical TAVR+TEER, and the immediate postoperative echocardiographic results revealed that none of them had more than mild perivalvular leakage and mitral regurgitation, and the prosthetic valves were in good position and function. At 1 week postoperatively, echocardiographic results showed 5 patients with no displacement of the prosthetic valve, detachment of the mitral clip, or damage to the leaflets. At 1 month postoperatively, cardiac function was improved to varying degrees in 4 patients, and 1 patient died of multiorgan failure. At 2 months postoperatively, 1 patient died of cerebrovascular accident, and at 3 months postoperatively the echocardiographic results of the remaining 3 patients revealed that there was no more than mild perivalvular leakage or mitral regurgitation, and the patients' postoperative cardiac function and daily life ability were significantly improved. Conclusion In high-risk aortic valve lesions combined with severe mitral regurgitation, "one-stop" transapical TAVR+TEER is feasible with favorable early efficacy and safety.

Objective:To explore the relationship between serum uric acid trajectory and the progression of renal function in individuals aged 60 and above.Methods:This study was a retrospective cohort study. Individuals aged 60 years and above who received health checkups in Beijing Friendship Hospital, Capital Medical University, from March 2015 to December 2023 and met the criteria of baseline estimated glomerular filtration rate (eGFR)≥60 ml·min -1·(1.73 m 2) -1, were selected as the research subjects. The serum uric acid data of multiple measurements were collected and identified as different serum uric acid trajectories by group-based trajectory modeling (GBTM). According to the serum uric acid trajectories, the subjects were divided into a low trajectory group (101 cases), a middle trajectory group (176 cases), and a high trajectory group (86 cases). Cox regression analysis was used to examine the effect of serum uric acid trajectory on the progression of renal function in the elderly. Results:A total of 363 elderly were included. The mean follow-up time was 8.1 years. At the end of the follow-up, a total of 50 elderly individuals had experienced varying degrees of renal function decline. After adjusting for multiple confounding factors by Cox regression analysis, the risks of eGFR<60 ml·min -1·(1.73 m 2) -1, eGFR reduction rate ≥25% and composite endpoints [eGFR <60 ml·min -1·(1.73 m 2) -1, eGFR reduction rate ≥25% or >3 ml·min -1·(1.73 m 2) -1·year -1] in the high trajectory group were significantly higher than those in the low trajectory group, with an HR of 4.54 (95% CI:1.47-20.76), 3.75 (95% CI:1.06-21.21), and 3.74 (95% CI:1.44-115.59), respectively. In addition, there was no significant difference between baseline serum uric acid and renal function progression (all P>0.05). Conclusion:The high serum uric acid trajectory increases the risk for the progression of renal function in individuals aged 60 and above.

Objective To observe the value of 18F-FDG PET/CT semi-quantitative parameters for predicting spread through air spaces(STAS)of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.Methods Data of 85 patients with clinical stage Ⅰa—Ⅲ a lung adenocarcinoma who underwent preoperative 18F-FDG PET/CT were retrospectively analyzed.The patients were divided into positive group(n=23)or negative group(n=62)according to whether pathology showed STAS or not.Clinical and PET/CT data were compared between groups,and logistic analysis was performed to explore the efficacy of each parameter for predicting STAS.Results Significant differences of gender,carcinoma embryonic antigen,clinical stage,pathological grade,micropapillary growth and proportion were found between groups(all P＜0.05).The maximum,the mean,the peak standard uptake value(SUVmax,SUVmean,SUVpeak),as well as the maximum,the mean and the peak standard uptake value normalized by lean body mass(SULmax,SULmean,SULpeak),also the total lesion glycolysis(TLG)in positive group were all significantly higher than those in negative group(all P＜0.05).Patients'gender,proportion of micropapillary growth,SUVmax and SULmax were all independent risk factors of STAS of clinical stage Ⅰa—Ⅲa lung adenocarcinoma.The area under the curve(AUC)of the above parameters for predicting STAS was 0.666,0.912,0.839 and 0.842,respectively,and of the combination was 0.957.Conclusion 18 F-FDG PET/CT semi-quantitative parameters SUVmax and SULmax were helpful for predicting STAS of clinical stage Ⅰa—Ⅲ a lung adenocarcinoma,and further combination of gender and proportion of micropapillary growth could improve diagnostic efficacy.

Objective:To explore the association between different feeding patterns, emotional states, and salivary oxytocin (OT) levels during breastfeeding.Methods:From January to December 2019, 153 pairs of 3-month-old infants and their mothers were recruited from 4 maternal and child health hospitals in Chongqing, Liuzhou, Dalian and Hangzhou in China.Saliva samples were collected from the mothers at the first 5 minutes of feeding, 5 minutes during feeding, and 10 minutes after feeding.Edinburgh postnatal depression scale (EPDS) was used to evaluate maternal depression.Infants were divided into exclusive breastfeeding group and artificial feeding group according to feeding patterns.ELISA of salivary oxytocin was performed by ELISA kits, and the OT levels measured at the 3 time points were converted using linear interpolation.Area under the curve with respect to ground(OTAUCG) was used to represent the total concentration of salivary OT during the mother's breastfeeding.SPSS 25.0 software was used for statistical analysis.Multiple linear regression analysis and two factors analysis of variance were used to explore the association between different feeding methods, emotional state and salivary oxytocin during breastfeeding.Results:The results of the two factors analysis of variance showed that the interaction between feeding pattern and mother's emotion was not significant ( F=2.440, P=0.120), the main effect of mother's emotion was not significant ( F=0.380, P=0.539), and the main effect of feeding style was significant ( F=3.350, P=0.021). The level of OTAUCG under pure breastfeeding ((151 561.47±75 738.11) pg/mL) was higher than that under artificial feeding ((122 269.03±65 029.88) pg/mL), and the difference was statistically significant ( P=0.02). There was no statistically significant difference in OTAUCG levels between mothers with normal emotions ((146 106.37±75 106.76) pg/mL) and mothers with depressed emotions ((129 079.56±67 565.87) pg/mL) ( P=0.221). Multiple stepwise regression analysis showed that artificial feeding had a negative predictive effect on maternal salivary OT levels compared to exclusive breastfeeding( β=-0.211, t=-2.513, P=0.013). Conclusion:Feeding pattern is a factor that affects the mother's salivary OT level, and breastfeeding can improve the mother's OT level.

Purpose: The human epidermal growth factor receptor 2 (HER2) is an established therapeutic target for various kinds of solid tumors. HER2 amplification occurs in approximately 1% to 6% of colorectal cancer. In this study, we aimed to assess the efficacy and safety of trastuzumab in combination with chemotherapy in HER2-positive metastatic colorectal cancer (mCRC). Materials and Methods: An open-label, phase II trial (Clinicaltrials.gov: NCT03185988) was designed to evaluate the antitumor activity of trastuzumab and chemotherapy in HER2-positive digestive cancers excluding gastric cancer in 2017. Patients from this trial with HER2-positive, KRAS/BRAF wild-type, unresectable mCRC were analyzed in this manuscript. Eligible patients were treated with trastuzumab (8 mg/kg loading dose and then 6 mg/kg every 3 weeks) and irinotecan (120 mg/m2 days 1 and 8 every 3 weeks). The primary endpoint was the objective response rate. Results: Twenty-one HER2-positive mCRC patients were enrolled in this study. Seven patients (33.3%) achieved an objective res-ponse, and 11 patients (52.4%) had stable disease as their best response. The median progression-free survival (PFS) was 4.3 months (95% confidence interval, 2.7 to 5.9). Four of the 21 patients (19.0%) had grade 3 adverse events, including leukopenia, neutropenia, urinary tract infection, and diarrhea. No treatment-related death was reported. Exploratory analyses revealed that high tumor tissue HER2 copy number was associated with better therapeutic response and PFS. Alterations in the mitogen-activated protein kinase pathway, HER2 gene, phosphoinositide 3-kinase/AKT pathway, and cell cycle control genes were potential drivers of trastuzumab resistance in mCRC. Conclusion Trastuzumab combined with chemotherapy is a potentially effective and well-tolerated therapeutic regimen in mCRC with a high HER2 copy number.
