ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus（WAOF） and cultivated Alpiniae Oxyphyllae Fructus（CAOF） through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF， followed by microscopic identification， thin-layer chromatography（TLC） identification， moisture content（toluene method）， total ash， acid-insoluble ash， water-soluble and alcohol-soluble extracts（hot dipping method）， water-soluble protein， total polysaccharides and total flavonoids（ultraviolet spectrophotometry）， and volatile oil content（method A under general rule 2204）. The contents of five active components（protocatechuic acid， chrysin， kaempferol， tectochrysin and nootkatone） were quantified using ultra-performance liquid chromatography（UPLC）， and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF， quantitative measurements were conducted on its appearance traits including diameter， length， plumpness（diameter/length ratio）， and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation， TLC identification， moisture content， protocatechuic acid content， kaempferol content， odor， or antioxidant activity measured by 2，2ʹ-azino-bis（3-ethylbenzothiazoline-6-sulfonic acid）（ABTS） method. WAOF exhibited significantly higher levels in water-soluble extracts， alcohol-soluble extracts， total polysaccharide content， water-soluble protein content， 100-grain weight， length， and total color difference（ΔE^*ab） compared to CAOF（P<0.01）. In contrast， CAOF showed significantly higher levels of total ash， acid-insoluble ash， content of total flavonoids， volatile oil content， chrysin content， tectochrysin content， nootkatone content， diameter， plumpness， lightness（L^*）， red-green chromaticity（a^*）， yellow-blue chromaticity（b^*）， and antioxidant activity measured by 1，1-diphenyl-2-picrylhydrazyl（DPPH） method compared to WAOF（P<0.01）. Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits， plumpness， L^*， a^*， and b^* exerted significant influence on intrinsic quality. Among the quality traits， total flavonoids， volatile oils， nootkatone， chrysin， and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness， L^*， a^*， and b^* of AOF significantly influence its intrinsic quality， and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

The welfare and ethics of laboratory animals are the ethical principles and behavioral norms that need to be followed in conducting animal-based scientific research, breeding and managing laboratory animals, and supervising and regulating such activities. The level of protection of laboratory animal welfare and ethics is closely related to the development of science and technology, which has become a widely recognized international consensus. At present, Guangdong Province is accelerating the construction of a high-level science and technology innovation province and the Guangdong-Hong Kong-Macao Greater Bay Area International Science and Technology Innovation Center. Guangdong Province should rely on its advanced governance capacity in the field of laboratory animal science and technology ethics to promote the high-quality development of its laboratory animal science and technology sector. Based on the management laws, regulations, and institutional mechanisms of laboratory animals in China, this paper explores the optimization of the laboratory animal science and technology ethics governance system, which includes the institutional guarantees, responsibility systems, ethical review and supervision mechanisms, and education and outreach. Through methods such as literature research, questionnaire surveys, and interview investigations, an empirical study of the laboratory animal science and technology ethics governance system in Guangdong Province has been conducted. Analysis of literature and research results shows that Guangdong Province has basically established a laboratory animal management system, collaboration mechanism, supervision mechanism, and education and training system that meet the current requirements of the laboratory animal science and technology ethics governance system in China. However, there are still problems such as an incomplete laboratory animal science and technology ethics supervision mechanism, an underdeveloped operation mechanism of review institutions, insufficient attention paid by laboratory animal units to the ethical review of animal experiments, inconsistent ethical review standards, and a lack of professional ethical education and training for ethics review personnel. Therefore, optimization measures such as improving the laboratory animal science and technology ethics review system, strengthening supervision and inspection, further strengthening the accountability of responsible entities, formulating review norms, and enhancing hierarchical and classified education and training are proposed, to provide a theoretical basis for promoting the normalized and long-term governance of laboratory animal science and technology ethics in Guangdong Province.

Objective: To explore the influence of different exercise duration and types on immediate emotion and stress relief of college students, and clarify the optimal duration and type of exercise, so as to provide empirical evidence for the formulation of mental health promotion strategies in colleges and univeristies. Methods: From March to June 2025, a randomized controlled trial design was used to recruit 240 college students from 3 universities in Henan Province. The subjects were randomly divided into control group (rest), 5 minute exercise group, 10 minute exercise group and 15 minute exercise group by random number table method, with 60 students in each group. Each exercise group was further divided into 3 subgroups (20 students in each group):moderate intensity aerobic exercise, stretching relaxation, and core strength training, the intervention tool place from 16:00 to 18:00 . The Positive and Negative Affect Schedule (PANAS), State Anxiety Inventory (SAI) and Perceived Stress Scale-4 (PSS-4) were used to evaluate the immediate emotion and stress levels before and after intervention. Repeated measures ANOVA and multiple linear regression analysis were used to explore the intervention effect of short term exercise. Results: After intervention, the results of one way ANOVA showed that there were statistically significant differences in the scores of positive emotion, negative emotion, state anxiety, and perceived stress between each exercise group (5, 10, 15 min) and the control group ( F =58.63, 42.18 , 51.31, 47.83, all P <0.01). Further pairwise comparisons revealed that the improvement effects of the 10 min exercise group in each index (31.27±5.38, 12.15±4.08, 32.17±5.98, 5.64±1.98) were superior to those of the control group (22.98±5.30, 18.70±4.32, 42.52±6.25, 9.31±2.15) and the 5 min exercise group (27.65±5.42, 15.32±4.17, 36.84±6.07, 7.25±2.02) (all P < 0.05). There were statistically significant differences in the scores of positive emotion, negative emotion, state anxiety, and perceived stress among different types of short term exercises ( F =12.74, 10.68, 13.55, 11.21, all P <0.01). Further pairwise comparisons revealed that the intervention effects of the stretching and relaxation group and the moderate intensity aerobic exercise group were superior to those of the core strength group (all P <0.05). Multiple linear regression analysis showed that 10 minute moderate intensity aerobic exercise and 10 minute stretching relaxation could positively predict the improvement of positive affect ( β = 0.42, 0.39, both P <0.01), and negatively predict the levels of negative affect, state anxiety and perceived stress ( β =-0.37 to -0.34, all P <0.01). Conclusions Appropriate exercise duration and different types of exercise can significantly improve college students immediate emotional state and relieve acute stress. Among them, 10 minute moderate intensity aerobic exercise or stretching and relaxation is the optimal option for college students in short duration exercise scenarios, which can serve as an important supplementary measure for mental health promotion in colleges and universities.

Cardiovascular diseases have the very high morbidity and mortality in the world.In recent years,the pharmacological effect and mechanism of Ganoderma lucidum has become the focus of research.Ganoderma lucidum,a traditional Chinese medicine,has broad development prospects and resource reserves.However,the mechanism of Ganoderma lucidum prevention and treatment of cardiovascular diseases is still lack of a complete review.In this paper,several domestic and foreign databases including CNKI and PubMed were searched to summarize the research progress of Ganoderma lucidum in anti-atherosclerosis,lowering blood lipids and lowering blood pressure in recent ten years.The main pharmacological mechanisms of Ganoderma lucidum in preventing and treating cardiovascular diseases include anti-inflammation,anti-oxidative stress,regulation of mitochondrial function,inhibition of calcium overload,regulation of intestinal flora and maintenance of cholesterol balance.On this basis.In addition,the paper also proposes to strengthen the in-depth study of Ganoderma lucidum in preventing and treating cardiovascular diseases,and pointed out the shortcomings of the existing research on Ganoderma lucidum,which provided some reference and guidance for promoting the in-depth study of its mechanism of action and clinical transformation of drugs.

This study utilized data from the non-communicable diseases (NCDs) Progress Monitor Reports (2015, 2017, 2020, 2022) released by World Health Organization (WHO) to analyze the implementation of NCDs prevention and control policies in China from 2014 to 2021 through descriptive statistical method, aiming to provide evidence for strengthening national NCDs strategies. The analysis focuses on WHO-recommended ‘best buys’ policies for NCDs prevention and control, covering 10 categories (18 interventions): national NCDs targets, mortality data, risk factor surveys, national integrated NCDs policies/strategies/action plans, tobacco demand-reduction measures, harmful use of alcohol reduction measures, unhealthy diet reduction policies, physical activity campaigns, national clinical guidelines for cancer/CVD/diabetes/CRD management, and drug therapy/counselling for cardiovascular diseases. In accordance with the WHO′s NCDs progress monitor scoring methodology, policies are assigned 1.0 point for full implementation, 0.5 points for partial implementation, and 0 points for non-implementation or missing data, with a maximum total score of 18.0 points. The analytical metrics encompass the policy implementation score, implementation rate, and period-on-period implementation growth rate. The results showed that China′s total policy implementation scores for NCDs prevention and control in 2014, 2016, 2019, and 2021 were consistently higher than the global average (8.5, 10.5, 9.5, 9.5 vs 6.7, 8.3, 8.6, 8.6). From 2014 to 2021, the total score increased by 1.0 point, and the implementation rate improved by 8.9%. From 2014 to 2016, China′s total policy implementation score rose from 8.5 to 10.5, primarily driven by improvements in tobacco tax increases and unhealthy diet reduction measures (salt reduction, restrictions on high-fat foods, and regulation of breast-milk substitute sales). However, this progress was partially offset by a decline in scores for physical activity campaigns. From 2016 to 2019, the total score decreased to 9.5, largely due to lower scores in harmful use of alcohol reduction measures (alcohol taxation and advertising bans). From 2019 to 2021, the total score remained stable, with increases in marketing to children restrictions balanced by declines in scores for drug therapy/counselling for cardiovascular diseases. In 2021, China′s total policy implementation score (9.5) exceeded the global average (8.6) but fell below the G20 average (11.2). Significant gaps remained compared to top-performing G20 countries such as Turkey (16.5), particularly in tobacco control and restrictions on harmful alcohol use. In conclusion, from 2014 to 2021, China′s total policy implementation score for NCDs prevention and control consistently exceeded the global average, demonstrating an upward trend, and various NCDs prevention and control policies have been continuously improved.

Objective:To compare the diagnostic efficacy of 18F-fibroblast activation protein inhibitor (FAPI)-42 PET/CT and 18F-FDG PET/CT for bone metastasis in patients with malignant tumors. Methods:From January 2022 to October 2023, the data of 238 patients (160 males, 78 females; age: 58(50, 66) years) with various malignant tumors who underwent both 18F-FAPI-42 and 18F-FDG PET/CT imaging at Nanfang Hospital, Southern Medical University were retrospectively reviewed. An abnormal focal radioactive uptake in bones on the PET images was considered as positive lesion for bone metastasis. The efficacy of 2imaging methods and the supplementary role of CT in the diagnosis of bone metastasis were evaluated by McNemar test. Results:Of 238 patients, 95 were with bone metastases and 143 were without bone metastases, including 436 lesions with bone metastases and 358 lesions without bone metastases. Based on the visual analysis, 18F-FAPI-42 PET showed a higher diagnostic sensitivity than 18F-FDG PET (98.4%(429/436) vs 86.5%(377/436); χ2=41.95, P<0.001), while 18F-FDG PET had a higher diagnostic specificity than 18F-FAPI-42 PET (83.2%(298/358) vs 70.4%(252/358); χ2=22.50, P<0.001), and the accuracies of both methods were similar (85.8%(681/794) vs 85.0%(675/794); χ2=0.16, P=0.685). However, when the positive lesions seen in PET were analyzed combined with the image features on CT by the same scanner, the diagnostic specificity of 18F-FAPI-42 PET/CT was significantly improved compared to that of 18F-FAPI-42 PET alone (91.3%(327/358) vs 70.4%(252/358); χ2=73.01, P<0.001), and was similar to 18F-FDG PET/CT (93.0%(333/358); χ2=0.78, P=0.377). Meanwhile, this combined analysis brought a higher sensitivity and accuracy of 18F-FAPI-42 PET/CT than 18F-FDG PET/CT in diagnosing bone metastases (sensitivity: 98.4%(429/436) vs 86.5%(377/436); χ2=41.95, P<0.001; accuracy: 95.2%(756/794) vs 89.4%(710/794); χ2=21.54, P<0.001). Conclusions:The diagnostic sensitivity of 18F-FAPI-42 PET for bone metastasis is superior to 18F-FDG PET, but the specificity is lower. However, when CT features is combined for analysis, the diagnostic specificity of 18F-FAPI-42 PET/CT is significantly improved, which thus can be used to diagnose bone metastasis accurately and is superior to 18F-FDG PET/CT.

Objective:To investigate the current status and risk factors of central venous catheter-related thrombus（CRT）in critically ill children，and to provide evidence for proposing preventive measures.Methods:This study was a single-center cross-sectional survey.The hospitalized children with central venous catheters implanted in the intensive care unit of Shanghai Children's Medical Center,Shanghai Jiao Tong University School of Medicine from January to March 2024 were included.Based on the ultrasound diagnosis indicating CRT or the presence of visually detectable thrombi after central venous catheter removal,the children included in the study were categorized into the CRT group and the non-CRT group.The data of demographic，clinical data，laboratory tests，medication treatment，and catheter related information of the affected children were collected.Univariate and multivariate analyses were performed to identify risk factors associated with CRT.Results:A total of 328 children were included，of which 158 cases（48.2%）were female，with the median age of 35.00（9.00，88.75）months.There were 51 cases（15.6%）in CRT group and 277 cases（84.4%）in non-CRT group.After adjusted by pediatric critical illness score，multivariate binary Logistic analysis revealed that the use of normal saline for catheter flushing and sealing (adjust OR=26.52,95% CI 8.32-84.60, P<0.001),longer duration of vasoactive drug use (adjust OR=5.06,95% CI 1.93-13.26, P=0.001),higher Caprini scale score (adjust OR=3.09,95% CI 1.38-6.91, P=0.006),presence of high-risk comorbidities or complications (adjust OR=2.87,95% CI 1.11-7.45, P=0.030),longer immobilization time (adjust OR=1.13,95% CI 1.07-1.19, P<0.001),and lower international normalized ratio after catheter placement (adjust OR=0.10,95% CI 0.02-0.53, P=0.007) were independent risk factors affecting the occurrence of CRT. Conclusion:The incidence of CRT is relatively high among critically ill children,and medical staff can develop targeted intervention measures by taking relevant risk factors into consideration.

Through consulting herbal medicine， medical books， and local chronicles from past dynasties to modern times， this paper systematically researched Spatholobi Caulis from name， origin， producing areas， harvesting， processing， usage， quality evaluation， functions and indications， providing a reference for the development and utilization of famous classical formulas containing Spatholobi Caulis. According to the research， Spatholobi Caulis was first recorded in the Annals of Shunning Prefecture from the Qing dynasty. It was originally a medicinal herb commonly used in Shunning， Yunnan， and was named from the red juice resembling chicken blood that flowed out after the vein was cut off. The mainstream original plants of each dynasty were Kadsura heteroclita and Spatholobus suberectus. Among them， K. heteroclita mainly focused on dispersing blood stasis and unblocking meridians， mainly treating rheumatic pain and injuries caused by falls or blows， and it is mostly used as the raw material of Jixueteng ointments. S. suberectus was commonly used as decoction pieces in decoction， which had the functions of promoting blood circulation and replenishing blood， activating meridians and collaterals， and mainly used for treating anemia， irregular menstruation， and rheumatic bone pain. The production area of Spatholobi Caulis recorded in the Qing dynasty was Yunnan. Currently， the main production area of S. suberectus is Guangxi， while the main production area of K. interior is Yunnan. In the Qing dynasty， the usage of Spatholobi Caulis was an individual prescription with other herbs before making ointments， which was usually composed of the juice of it， safflower， angelica， and glutinous rice. But in modern times， Spatholobi Caulis is mostly sliced and dried for use. The quality of Spatholobi Caulis is often determined by the number of reddish-brown concentric circles on the cut surface， with a higher number indicating better quality. Additionally， the presence of resinous secretions is also considered desirable. Based on the research findings， it is suggested that when developing famous classical formulas containing Spatholobi Caulis， the choice of the primary source should be S. suberectus or K. heteroclita， taking into consideration the therapeutic effects of the formula. It is also recommended that the latest plant classification be referenced in the next edition of Chinese Pharmacopoeia， adjusting the primary source of Kadsurae Caulis to K. heteroclita to avoid confusion caused by inconsistent original names， and the functions adjust to promote Qi circulation and relieve pain， disperse blood stasis and unblock collaterals， treating injuries caused by falls and bruises.

However, when the positive lesions seen in PET were analyzed combined with the image features on CT by the same scanner, the diagnostic specificity of 18F-FAPI-42 PET/CT was significantly improved compared to that of 18F-FAPI-42 PET alone (91.3%(327/358) vs 70.4%(252/358); χ2=73.01, P<0.001), and was similar to 18F-FDG PET/CT (93.0%(333/358); χ2=0.78, P=0.377). Meanwhile, this combined analysis brought a higher sensitivity and accuracy of 18F-FAPI-42 PET/CT than 18F-FDG PET/CT in diagnosing bone metastases (sensitivity: 98.4%(429/436) vs 86.5%(377/436); χ2=41.95, P<0.001; accuracy: 95.2%(756/794) vs 89.4%(710/794); χ2=21.54, P<0.001). Conclusions:The diagnostic sensitivity of 18F-FAPI-42 PET for bone metastasis is superior to 18F-FDG PET, but the specificity is lower. However, when CT features is combined for analysis, the diagnostic specificity of 18F-FAPI-42 PET/CT is significantly improved, which thus can be used to diagnose bone metastasis accurately and is superior to 18F-FDG PET/CT.
