OBJECTIVE To analyze the differences in chemical components of Gardenia jasminoides before and after processing with ginger， and to evaluate the quality differences among different producing areas. METHODS Ultra-high performance liquid chromatography-tandem time-of-flight mass spectrometry was used to analyze the compositional differences of G. jasminoides before and after processing with ginger. The water content， total ash， and ethanol-soluble extract content of ginger- processed G. jasminoides were determined according to the 2020 edition of Chinese Pharmacopoeia. High performance liquid chromatography was adopted to determine the contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ in ginger- processed G. jasminoides. RESULTS A total of 49 chemical components were identified from raw G. jasminoides and ginger- processed G. jasminoides， including 14 flavonoids， 15 iridoids， 10 organic acids， 2 alkaloids and 8 other compounds. Among them， 42 components were detected in raw G. jasminoides， 28 in ginger-processed G. jasminoides， and 21 components were common to both. After processing with ginger， raw G. jasminoides lost 21 components （including iridoids， flavonoids， alkaloids， and others）， while 7 chemical components were added （including coumarins， organic acids， organic acid esters， and flavonoids）. For the 15 batches of ginger-processed G. jasminoides， the water content ranged from 5.64% to 7.11%， total ash from 2.92% to 4.87%， and ethanol-soluble extract from 40.61% to 58.02%. The average contents of genipin gentiobioside， geniposide， crocin Ⅰ and crocin Ⅱ were 0.108 7， 0.542 2， 0.565 0， and 0.012 5 mg/g， respectively. CONCLUSIONS After processing with ginger， G. jasminoides loses 21 components， while 7 new components are added. Differences are observed in the water content， total ash， ethanol-soluble extract， and the contents of genipin gentiobioside， geniposide， crocin Ⅰ， and crocin Ⅱ of ginger-processed G. jasminoides from different producing areas. Notably， samples from Fujian exhibit high contents of genipin gentiobioside and ethanol-soluble extract， while samples from Jiangxi have a high content of crocin Ⅰ.

Mitochondrial biogenesis represents a promising therapeutic target in triple-negative breast cancer (TNBC) due to its essential role in cancer cell metabolism and survival. The natural compound γ-Elemene exhibits potent anti-tumor activity, but its effects on mitochondrial regulation in TNBC remain unclear. In this study, we demonstrate that γ-Elemene induces dose-dependent cytotoxicity in MDA-MB-468 and HCC1806 TNBC cells while significantly impairing mitochondrial function, as shown by reduced membrane potential, oxidative phosphorylation capacity, and ATP production. γ-Elemene treatment markedly suppressed mitochondrial biogenesis, decreasing mitochondrial DNA content and downregulating key mitochondrial genes and proteins. These effects were associated with reduced expression of the master regulators NRF1 and TFAM, but independent of PGC-1α expression levels.Mechanistically, γ-Elemene upregulated the acetyltransferase GCN5, leading to enhanced PGC-1α acetylation. This upregulation occurs primarily through increased GCN5 transcription. Genetic ablation of GCN5 completely reversed γ-Elemene-induced PGC-1α acetylation and restored mitochondrial biogenesis and cell viability, establishing a critical role for GCN5 in mediating these effects. Our findings reveal a novel mechanism whereby γ-Elemene disrupts mitochondrial function in TNBC through GCN5-mediated PGC-1α acetylation, providing new insights into its anti-cancer properties and potential therapeutic applications against TNBC.

Abstract To clarify the service targets, service contents, and safeguard mechanisms of the basic public service program for student vision health management, the study grounded in the current status of child and adolescent myopia prevention and control in China and integrated with the practical experience and innovative practices of Wuhan National Demonstration Area for Student Vision Health Management, takes education as the main thread and schools as the base, consolidating resources from multiple stakeholders including education administrative departments, schools, families, and professional technical service institutions. Centering on four core components—vision health education, monitoring and record keeping, risk prevention and control, and dynamic management, the study constructs a multi tiered basic public service system for vision health management of primary and secondary school students. It further proposes the use of an intelligent management platform and a "three tier color coded early warning" mechanism (red, yellow, blue) to prevent and control student myopia at the source, providing schools with replicable and operable implementation pathways to enhance the level of student vision health management.

ObjectiveSeveral molecular markers were evaluated for their reliability in detecting Angiostrongylus cantonensis in wild rodent feces and for determining the infection status of these rodents. MethodsA total of 128 wild rodents were captured in Huashan Town， Huadu district， Guangzhou. Their fecal samples were collected and total DNA was extracted with the FastDNA SPIN Kit for Soil. PCR amplification was performed to obtain cytb， cox I and ITS2 gene fragments， followed by Sanger sequencing and phylogenetical analysis. ResultsAmong all 128 fecal samples， only 5 had clean PCR bands and unambiguous cytb sequences suitable for reliable species identification. The infection rate of A. cantonensis was 7.58% （5/66） in Rattus norvegicus， whereas no cytb fragments were detected in Rattus tanezumi， Rattus losea， Suncus murinus and Bandicota indica. These data indicate that R. norvegicus is a highly suitable host for A. cantonensis， and the cytb gene serves as an effective molecular marker for detecting A. cantonensis in wild rodent feces. ConclusionThe cytb is an effective molecular marker for detecting A. cantonensis in wild rodent feces， enabling long-term surveillance of its prevalence and potential public health threat.

Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding for overweight and obese young adults with phlegm-dampness constitution. METHODS: A total of 66 young adults with overweight and obesity of phlegm-dampness constitution were randomly divided into an observation group (33 cases, 2 cases dropped out, 1 case was discontinued) and a control group (33 cases, 3 cases dropped out). Health education guidance was adopted in the control group. On the basis of the intervention in the control group, acupoint thread-embedding was applied in the observation group, two groups of acupoints were used alternately, i.e. bilateral Tianshu (ST25), Daheng (SP15), Daimai (GB26), Shuidao (ST28), Huaroumen (ST24), Fenglong (ST40) and bilateral Feishu (BL13), Geshu (BL17), Weiwanxiashu (EX-B3), Pishu (BL20), Shenshu (BL23), Dachangshu (BL25), once a week. Treatment of 8 weeks was required in the two groups. Before treatment, after 4 weeks and 8 weeks of treatment, the body weight, body fat rate, waist circumference and hip circumference were measured, and the body mass index (BMI) was calculated in the two groups; before and after treatment, the phlegm-dampness constitution score and the heart rate variability (HRV) related indexes (total power [TP], low frequency [LF], high frequency [HF], LF/HF, standard deviation of the normal to normal inter beat intervals [SDNN], root mean square of the successive differences [RMSSD], percentage of normal RR intervals with duration [PNN50]) were observed, and the clinical efficacy and constitution improvement rate were compared in the two groups. Six months after the treatment completion, the body weight of patients with effective clinical efficacy was observed, and the body weight rebound rate was compared in the two groups. RESULTS: After 4 weeks of treatment, the body weight, BMI, body fat rate, waist circumference and hip circumference were decreased compared with those before treatment in the two groups (P<0.05); after 8 weeks of treatment, the body weight, BMI, body fat rate, waist circumference and hip circumference were decreased compared with those before treatment and after 4 weeks of treatment in the observation group (P<0.05), and the body weight was decreased compared with that before treatment in the control group (P<0.05). After 8 weeks of treatment, the body weight, BMI, waist circumference, hip circumference and phlegm-dampness constitution score in the observation group were lower than those in the control group (P<0.05). The differences in the body weight, BMI, body fat rate, waist circumference and hip circumference between before treatment and after 4 weeks of treatment, as well as after 4 weeks of treatment and after 8 weeks of treatment in the observation group were higher than those in the control group (P<0.05). After treatment, the TP, LF, HF, SDNN and RMSSD in the observation group were higher than those in the control group (P<0.05). After treatment, the total effective rate was 90.0% (27/30) in the observation group, which was higher than 46.7% (14/30) in the control group (P<0.05); the improvement rate of phlegm-dampness constitution was 90.0% (27/30) in the observation group, which was higher than 50.0% (15/30) in the control group (P<0.05). Six months after treatment completion, the weight rebound rate was 37.0% (10/27) in the observation group, which was lower than 71.4% (10/14) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding can effectively reduce the body weight, BMI, waist circumference, hip circumference and improve the phlegm-dampness constitution in overweight and obese young adults with phlegm-dampness constitution, regulate autonomic nerve disorders and improve vagus nerve activity, and has a certain long-term effect.

OBJECTIVE: To observe the effects of Yisui Yangxin moxibustion (moxibustion for benefiting the marrow and nourishing the heart) in sequential trial on blood pressure (BP), perimenopausal symptoms, cardiovascular function and heart rate variability (HRV) in prehypertension in perimenopausal women. METHODS: The eligible female patients of prehypertension of perimenopausal period were collected according to the inclusion criteria. Based on the requirements of open two-way qualitative response sequential trial, the sample size was not set in advance, and the matched pair design was used for random division into a moxibustion group and a health education group. The patients of the two groups were treated in pairs, and the analysis was immediately performed after the end of treatment for each pair, and the sequential trial analysis (STA) was diagrammed. The health education group provided the health education for prehypertension to the patients according to 2018 Revised Chinese Hypertension Prevention and Treatment Guidelines. In the moxibustion group, beside the health education for prehypertension, the non-suppurative moxibustion was delivered at Baihui (GV20), Guanyuan (CV4) and bilateral Neiguan (PC6) and Zusanli (ST36), once every two days, 3 treatments per week and for 4 consecutive weeks. Before treatment, in 2 and 4 weeks of treatment, as well as in 1-month follow-up after treatment, BP was measured in each group, separately. Before treatment and in 4 weeks of treatment, the observation was performed in the score of the modified Kupperman scale, and Pittsburgh sleep quality index (PSQI) score, the indexes of cardiovascular function (stroke volume [SV], cardiac output per minute [CO], stroke index [SI], cardiac index [CI], left ventricular effective pumping force [VPE], left ventricular energy efficiency [EWK], arterial compliance [AC], left ventricular ejection resistance [VER], blood viscosity (N), and microcirculation half update rate [MHR]), and heart rate variability (HRV) indexes (low frequency [LF], high frequency [HF], LF/HF, standard deviation of NN interval [SDNN], root mean square of successive differences in adjacent NN intervals [RMSSD]). RESULTS: Based on sequential test line, when the trial was performed to the 17th pair, and the test line touched the upper limit U, meaning the results of the moxibustion group was superior to the health education group, thus, the trial stopped immediately. In 2 and 4 weeks of treatment and in follow-up, the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were lower when compared with those before treatment in the moxibustion group (P<0.05); SBP at each time point and DBP in 2 and 4 weeks of treatment in the moxibustion group were lower than those of the health education group (P<0.05). After treatment, the score of the modified Kupperman scale was reduced when compared with that before treatment in the moxibustion group (P<0.05). The score of the modified Kupperman scale and PSQI in the moxibustion group were lower than those of the health education group after treatment (P<0.05). After treatment, SV, CO, SI, CI and EWK were increased in comparison with the indexes before treatment in the moxibustion group (P<0.05), and VER and N were dropped (P<0.05). After treatment, SV, CO, SI, CI and EWK in the moxibustion group were higher than those of the health education group (P<0.05), and VER and N were lower (P<0.05). After treatment, in the moxibustion group, LF, HF, SDNN and RMSSD were increased in comparison with those before treatment (P<0.05), and LF/HF was declined (P<0.05). In the health education group, after treatment, LF, HF, SDNN and RMSSD decreased when compared with those before treatment (P<0.05). After treatment, LF, HF, SDNN and RMSSD in the moxibustion group were higher than those of the health education group (P<0.05), and LF/HF was lower (P<0.05). The total effective rate was 94.1% (16/17) in the moxibustion group, higher than that (41.2%, 7/17) in the health education group (P<0.05). CONCLUSION Moxibustion can reduce SBP and DBP in prehypertension of perimenopausal women, alleviate perimenopausal symptoms, improve cardiac function and adjust the overall balance of cardiac autonomic nerves.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.
