ObjectiveTo evaluate the pregnancy outcomes of assisted reproductive technology （ART） in women with a history of thyroid cancer who retained fertility intentions after completing cancer treatment. MethodsA retrospective analysis was performed on 61 patients with a history of thyroid cancer who underwent in vitro fertilization/intracytoplasmic sperm microinjection and embryo transfer （IVF/ICSI-ET）. These patients were included as the case group. A total of 122 non-cancer patients who received ART during the same period were selected as the control group using 1∶2 matching based on age and oocyte retrieval time. Baseline characteristics， outcomes of the first ART cycle， and cumulative pregnancy outcomes were compared between the two groups. ResultsThere was no significant difference in the basic data， the total amount of gonadotropin （Gn） and the days of use between the case group and the control group （P>0.05）. However， the case group had significantly fewer retrieved oocytes， mature oocytes （MII）， lower fertilization and cleavage rates， and fewer transferable and high-quality embryos， as well as fewer embryos transferred during the first cycle （P < 0.05）. However， there was no significant difference in the rate of first embryo implantation and first clinical pregnancy between the two groups （P>0.05）. In the analysis of cumulative outcomes， the two groups did not show statistically significant differences in the cumulative pregnancy rate， clinical pregnancy rate per transfer cycle， the number of oocyte retrieval cycles required per live birth， the number of embryo transfer cycles required per live birth， and the number of embryos used for each live birth （P>0.05）. However， the cumulative live birth rate was significantly lower in the case group compared to the control group （P=0.005）. ConclusionAfter treatment for thyroid cancer， when ART is used to help pregnant women， the pregnancy outcome is comparable to that of women without tumors. Individualized reproductive management and timely fertility preservation strategies are recommended to optimize reproductive outcomes in this population.

These scales can provide scientific basis for clinical positioning， efficacy evaluation， and expansion of indications of new drugs. By analyzing the current hotspots and difficulties in research， this study aims to explore the important significance of these scales in the development of new drugs for spleen and stomach diseases， summarize the domestic research progress， and conduct comparative analyses with international studies. Future development trends are also discussed in order to promote the application of symptom and syndrome efficacy evaluation scales in the development of new drugs for spleen and stomach diseases and to advance the moder-nization process of TCM.

Objective The aim was to evaluate the effects of efforts directed toward controlling Oncomelania hupensis snails on small environmental modification projects in Anqing City to provide a reference for comprehensively controlling O. hupensis in hilly areas where schistosomiasis is endemic. Methods Field and retrospective surveys were conducted to collect data using questionnaires. The data from 35 questionnaires on small-scale environmental modification projects in Anqing City and the effects of snail obtained from monitoring forms were sorted. The data were descriptively analyzed using basic information on environmental modifications and investment costs. The Wilcoxon signed-rank test was used to compare snail status before and after environmental interventions. The Friedman test was applied to evaluate the changes in snail populations in the years after environmental intervention. Non-parametric independent sample tests were adopted to compare differences in the effects of different environmental interventions, environmental characteristics, and between project and control areas. Results A total of 35 environments altered from 2017 to 2023, including the creation of 29 ditches,1 dry land, and 5 pond-weirs. The main environmental interventions included hardening of ditches and pond-weirs as well as tilling with intercropping. The average investment costs of mortared rubble masonry hardening and tilling with intercropping were the highest(147.10 yuan/m2)and lowest(4.62 yuan/m2), respectively. The pre-intervention snail-infested area was 78 900 m2, which decreased to 18 100 m2, a decrease of 77.06%. After environmental intervention, the density and rate of living snails significantly decreased on frames with snails(P<0.001). In ditch environments, the smoothness of the ditch walls and the presence of snails in the upper reaches did not significantly decrease the living snail density; however, the presence of cracks on the inner side of the ditches significantly impacted the decline in the rate(P<0.001). No significant difference was found in the rates at which the living snail density or snail frame occurrence decreased among different environmental modification method. The effects of brick masonry, concrete, and mortared rubble masonry on snail control were significantly stronger than those of chemical snail control(P<0.01), whereas no significant difference was found in the decline in these two rates between project areas using other modification method and control areas using chemical snail control. Conclusions Schistosomiasis-prevention-oriented environmental interventions effectively eliminate snails from hilly snail-infested areas. Cost-effective modification method should be selected based on the environmental type, and post-modification monitoring and maintenance must be strengthened to further increase snail control effectiveness.

Objective To investigate the prevalence and related factors of sarcopenia among non–bedridden older adults in the community of Baoshan District using the China mini sarcopenia risk assessment 7 (C-MSRA-7) combined with Ishii scoring system. Methods The older individuals consulting at 20 community health stations in Baoshan District between April 2025 and June 2025 were enrolled. Data were collected using a general information questionnaire, a dietary and lifestyle habits survey, the C-MSRA-7, and the mini nutritional assessment-short form (MNA-SF). Handgrip strength and anthropometric measurements were also obtained. Individuals with both Ishii score and C-MSRA-7 results positive were classified into the sarcopenia risk group, while the remaining participants were assigned to the non–sarcopenia risk group. Differences in lifestyle habits, dietary patterns, and nutritional status between the two groups were compared. Results A total of 2 611 valid questionnaires were retrieved. Univariate analysis showed statistically significant differences in alcohol consumption, physical activity frequency, body mass index (BMI), nutritional status, activities of daily living, and regularity of three meals in sarcopenia risk group (n＝486) and non–sarcopenia risk group (n＝2 125, P<0.05). Logistic regression analysis showed that advanced age (75–84 years: OR＝2.55, 95%CI 2.03–3.21; ≥85 years: OR＝3.98, 95%CI 2.24–7.07), underweight status (OR＝2.19, 95%CI 1.50–3.19), weight loss＞2 kg (OR＝4.52, 95%CI 2.68–7.64) past 3 months, lack of regular physical activity (OR＝1.77, 95%CI 1.24–2.52) , and alcohol consumption (OR＝1.48, 95%CI 1.07–2.05) were independent risk factors for sarcopenia (P<0.05). Behaviors related to healthy diet, including daily milk consumption (OR＝0.40, 95%CI 0.30–0.52), regular three meals (OR＝0.56, 95%CI 0.41–0.78), and high-quality protein intake (OR＝0.70, 95%CI 0.52–0.94), were protective factors (P<0.05). Conclusions Sarcopenia among community–dwelling, non–bedridden older adults is closely associated with physical activity levels, dietary habits, and nutritional status. Early identification of individuals at risk, enhanced nutritional education, and timely implementation of nutritional interventions and exercise programs are recommended for this population.

BackgroundBoth modified Suanzaoren Decoction and estazolam serve as effective treatments for chronic insomnia disorder （CID）. Default mode network （DMN） dysfunction is recognized as the primary pathophysiological mechanism underlying CID. However， it remains unclear whether the two treatments exert their therapeutic effects via convergent modulation of DMN functional connectivity. ObjectiveTo investigate the convergent remodeling characteristics of bidirectional effective connectivity （EC） of core DMN nodes with both the intra-network and the remaining whole-brain regions in CID patients with Yin-deficiency and fire-hyperactivity syndrome following the treatment with modified Suanzaoren Decoction or estazolam， so as to provide neuroimaging evidence for the convergent neural mechanisms underlying the therapeutic effects of both therapies in treating CID. MethodsEighty-two patients diagnosed with CID according to the International Classification of Sleep Disorder， third edition （ICSD-3） were consecutively recruited from the outpatient clinic of the Inner Mongolia Autonomous Region Mental Health Center from October 2020 to September 2023. Based on treatment preference， patients were assigned to receive a 6-week intervention in either the modified Suanzaoren Decoction group （n=52） or the estazolam group （n=30）. Ultimately， 66 patients completed follow-up assessments （modified Suanzaoren Decoction group， n=41； estazolam group， n=25）. All CID patients underwent resting-state functional magnetic resonance imaging scanning before and after treatment. Core DMN nodes including medial prefrontal cortex （mPFC）， bilateral inferior parietal lobule （IPL）， and precuneus （PCUN） were selected as seed regions. Granger causality analysis （GCA） was employed to assess bidirectional EC between the seed regions and both the other intra-DMN nodes and the remaining whole-brain regions. Hepatic and renal function indices were detected pre- and post-treatment to evaluate the safety profiles of both treatments. ResultsAt baseline， significant between-group differences were identified in EC from the left IPL to the left middle fronto-orbital gyrus/gyrus rectus （t=5.24， Z=4.84， voxel-level P<0.001， cluster-level P<0.05， GRF-corrected）， with the modified Suanzaoren Decoction group exhibiting stronger EC than the estazolam group. No significant between-group differences were observed in EC between other core DMN nodes and remaining whole-brain regions （P>0.05）. Within-group pre- to post-treatment comparisons demonstrated consistent connectivity alterations in both groups. Specifically， EC from the left IPL to the supplementary motor area （SMA） decreased after treatment （modified Suanzaoren Decoction group： t=-6.28， Z=5.208； estazolam group： t=-5.58， Z=4.425）. Conversely， EC from the SMA to the left IPL increased （modified Suanzaoren Decoction group： t=5.89， Z=4.968； estazolam group： t=6.15， Z=4.720）. Furthermore， both groups demonstrated reduced EC from the PCUN to the left IPL （modified Suanzaoren Decoction group： t=-5.85， Z=4.94； estazolam group： t=-5.75， Z=4.515）， and elevated EC from the left IPL to the PCUN （modified Suanzaoren Decoction group： t=5.29， Z=4.579； estazolam group： t=4.55， Z=3.826） （voxel-level P<0.001， cluster-level P<0.05， GRF-corrected）. No significant pre- to post-treatment differences were observed in hepatic or renal function indices in either group （P>0.05）. ConclusionIn CID patients with Yin-deficiency and fire-hyperactivity syndrome， both modified Suanzaoren Decoction and estazolam induce convergent bidirectional remodeling of EC between the left IPL and the SMA and the PCUN. ［Funded by Natural Science Fund Project of Inner Mongolia Autonomous Region （number， 2019MS08099）； ClinicalTrials.gov number， NCT06452953］

OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

Objective To explore the application value of CMR myocardial strain technique in eld-erly males with HCM.Methods A retrospective analysis was conducted on 50 elderly male pa-tients who underwent CMR examination at the Second Medical Center of Chinese PLA General Hospital from April 2020 to December 2024.According to being diagnosed with HCM or not,they were divided into a HCM group(24 cases)and a control group(26 cases).Post-processing soft-ware CVI42 was used to obtain two sets of basic functional and strain parameters of the left ven-tricle(LV)and left atrium(LA).The parameters of LV included LV mass,LV mass index(LV massi),global longitudinal strain(GLS),and so on,while the parameters of LA included minimum LA volume(LAV),minimum LA volume index(LA VI),LA passive strain(εe),LA peak early negative strain rate(SRe)and LA peak late negative strain rate(SRa),etc.The two sets of LV and LA parameters of basic functional and strain were compared between the two groups.Results The HCM group had significant higher LV mass and LV massi and minimum LAV and LAVI,but lower GLS,εe,SRe and SRa in 2D and 3D speckle-tracking echocardiography than the control group(P＜0.05,P＜0.01).The AUC value of 2D GLS,SRa,and logistic regres-sion model in predicting HCM was 0.887(95％CI:0.766-0.959),0.740(95％CI:0.597-0.854),and 0.929(95％CI:0.820-0.983),respectively,with a sensitivity of 76.92％,57.69％,and 84.62％,and a specificity of 70.83％,83.33％,and 91.67％,respectively.The logistic regression model demonstrated higher AUC value,sensitivity,and specificity than 2D GLS and SRa.Conclusion CMR myocardial strain technology is of significant diagnostic value for elderly male patients with HCM.

Objective:To characterize the etiological and genetic features of pediatric influenza outbreaks in Changzhou between 2021 and 2024，with the goal of informing evidence-based prevention strategies and guiding effective management of influenza outbreaks in school settings.Methods:During the period of 2021 to 2024，throat swabs of influenza-like cases from school outbreaks in Changzhou were collected. These samples underwent real-time reverse transcription-polymerase chain reaction（RT-PCR）testing and virus isolation. Epidemiological data were integrated to conduct pathogenetic analysis. The HA genes of isolated strains were amplified and sequenced to perform genetic characterization.Results:Between 2021 and 2024，a total of 256 influenza outbreaks were reported in schools in Changzhou. A total of 3 201 specimens were collected，of which 2 245 were tested positive for influenza viruses，resulting in a positivity rate of 70.13%. The outbreak season was primarily concentrated from December to February each year，with settings predominantly distributed in primary schools（accounting for 73.83%）. The predominant epidemic strains were influenza A viruses，including 118 outbreaks caused by H1N1 and 104 by H3N2. A total of 74 influenza virus strains were successfully isolated from positive specimens，and sequencing of the hemagglutinin（HA）gene was completed. Phylogenetic analysis revealed that certain B/Victoria lineage strains（e.g.，B/Changzhou/01/2021）clustered closely with the vaccine strain B/Austria/3594/17（bootstrap support：99%）. Among influenza H1N1 strains，multiple isolates from 2023—2024 clustered within the same major branch as A/Victoria/4897/2022（bootstrap support：100%）. In contrast，the H3N2 strains exhibited a complex evolutionary pattern，showing variable genetic distances to vaccine strains from different years（e.g.，A/Massachusetts/18/2022，A/Darwin/6/2021）；some isolates were closely related to vaccine strains，while others were more distantly related and scattered across the phylogenetic tree.Conclusions:The influenza outbreak situation in schools was severe and has significant public health implications. Continuous surveillance is essential，and preventive strategies should be promptly adjusted based on the epidemiological and genetic characteristics of circulating strains.

BACKGROUND: Effective interventions during the coronavirus disease 2019 (COVID-19) pandemic require an understanding of patients' knowledge and perceptions that influence their behaviour. Our study assessed knowledge of COVID-19 among kidney transplant recipients and donors, hitherto unevaluated. METHODS: We conducted a cross-sectional survey among 325 kidney transplant recipients and 172 donors between 1 May 2020 and 30 June 2020. The survey questionnaire assessed knowledge levels of COVID-19, sociodemographic data, health status, psychosocial impact of COVID-19 and precautionary behaviours during the pandemic. RESULTS: The mean COVID-19 knowledge score of the study population was 7.5 (standard deviation: 2.2) out of 10. The mean score was significantly higher among kidney recipients compared to kidney donors (7.9 [1.9] vs. 6.7 [2.6]; P <0.001). Younger age (21-49 vs. ≥50 years) and higher education (diploma and higher vs. secondary and lower) were associated with significantly higher knowledge scores in donors, but not among recipients ( P -interactions ≤0.01). In both kidney recipients and donors, financial concerns and/or social isolation were associated with lower knowledge levels. CONCLUSIONS Concerted efforts are needed to improve COVID-19 knowledge in kidney transplant recipients and donors, particularly older donors, donors with lower education and patients with financial concerns or feelings of social isolation. Intensive patient education may mitigate the impact of education levels on COVID-19 knowledge levels.

In order to investigate whether the effect of Yuxuebi Tablets on the peripheral and central inflammation resolution of mice with inflammatory pain is related to their regulation of G protein-coupled receptor 37(GPR37), an inflammatory pain model was established by injecting complete Freund's adjuvant(CFA) into the paws of mice, with a sham-operated group receiving a similar volume of normal saline. The mice were assigned randomly to the sham-operated group, model group, ibuprofen group(91 mg·kg~(-1)), and low-, medium-, and high-dose groups of Yuxuebi Tablets(60, 120, and 240 mg·kg~(-1)). The drug was administered orally from days 1 to 19 after modeling. Von Frey method and the hot plate test were used to detect mechanical pain thresholds and heat hyperalgesia. The levels of interleukin-10(IL-10) and transforming growth factor-beta(TGF-β) in the spinal cord were quantified using enzyme-linked immunosorbent assay(ELISA), and the mRNA and protein expression of GPR37 in the spinal cord was measured by real-time quantitative reverse transcription PCR(qRT-PCR) and Western blot. Additionally, immunofluorescence was used to detect the expression of macrosialin antigen(CD68), mannose receptor(MRC1 or CD206), and GPR37 in dorsal root ganglia, as well as the expression of calcium-binding adapter molecule 1(IBA1), CD206, and GPR37 in the dorsal horn of the spinal cord. The results showed that compared with those of the sham-operated group, the mechanical pain thresholds and hot withdrawal latency of the model group significantly declined, and the expression of CD68 in the dorsal root ganglia and the expression of IBA1 in the dorsal horn of the spinal cord significantly increased. The expression of CD206 and GPR37 significantly decreased in the dorsal root ganglion and dorsal horn of the spinal cord, and IL-10 and TGF-β levels in the spinal cord were significantly decreased. Compared with those of the model group, the mechanical pain thresholds and hot withdrawal latency of the high-dose group of Yuxuebi Tablets significantly increased, and the expression of CD68 in the dorsal root ganglion and IBA1 in the dorsal horn of the spinal cord significantly decreased. The expression of CD206 and GPR37 in the dorsal root ganglion and dorsal horn of the spinal cord significantly increased, as well as IL-10 and TGF-β levels in the spinal cord. These findings indicated that Yuxuebi Tablets may reduce macrophage(microglial) infiltration and foster M2 macrophage polarization by enhancing GPR37 expression in the dorsal root ganglia and dorsal horn of the spinal cord of CFA-induced mice, so as to improve IL-10 and TGF-β levels, promote resolution of both peripheral and central inflammation, and play analgesic effects.
