With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

According to the "Regulations on clinical application management of medical technologies", physicians intending to carry out restricted technologies must undergo standardized training and pass assessments in accordance with the clinical application management standards for the respective technology. As ventricular assist technology is classified as a nationally restricted technology, standardized training is one of the essential conditions for its application. This paper primarily explores the standardized training for the clinical application of ventricular assist technology in Shanghai, in light of its background, clinical application, and current training status. It proposes the training requirements for ventricular assist technology, animal training assessment standards, and clinical practice assessment standards in Shanghai, aiming to promote the standardized development and high-quality advancement of ventricular assist technology in Shanghai.

Objective: To systematically review the development and changes in mental health policies within the National Outline for Children s Development in China from 1992 to 2030, providing a reference basis for future formulation of mental health policies among children and adolescent in China. Methods: Based on the four editions of the National Outline for Children s Development in China across different periods from 1992 to 2030, word frequency analysis was used to reveal shifts in policy priorities, and an internationally recognized framework for adolescent health policy analysis was applied to conduct a textual review. Results: Word frequency analysis revealed that the term "psychological" appeared 6 times in the National Outline for Children s Development in China (2001-2010) but increased to 20 times in the National Outline for Children s Development in China (2021-2030) (abbreviated as the National Outline of 2021), while the term "health" rose from 4 times in the National Outline for Children s Development Plan in China in the 1990s to 68 times in the National Outline of 2021. The scope of mental health policy interventions expanded to encompass five key areas:health, safety, education, welfare and legal protection. Textual analysis highlighted that the policies of the National Outline for Children s Development in China were demand driven, prioritized vulnerable groups and continuously broadened their coverage, emphasizing sustainability and appropriateness, and monitoring/evaluation mechanisms. By 2023, 42.3% of primary schools and 64.8% of secondary schools employed full time mental health education teachers. However, the National Outline for Children s Development in China lacked direct evidence of children and adolescents participation in policy formulation, and publicly available mental health data disaggregated by age and gender remained limited. Conclusion Mental health policies of children and adolescents in China have evolved from nonexistence to gradual refinement, yet institutionalized channels for youth involvement in policy development and evaluation remain insufficient, and transparency in age and gender specific mental health data needs improvement.

Objective To analyze the survival status of inpatients with cervical cancer registered in Nantong admitted in Nantong Cancer Hospital from 2002 to 2017. Methods Inpatients with cervical cancer in Nantong Cancer Hospital were followed up from 2017 until December 31, 2020 using active and passive methods to determine their survival outcome. The rate of follow-up loss was statistically analyzed by Chi-square test, the observed survival rate for each year was calculated using the life table, the survival curve was drawn with R language, and the survival rates of patients in different age groups and from different regions were compared with log-rank test (Mantel-Cox). Results A total of 5645 cervical cancer cases were registered. Among them, the survival outcome was recorded for 5512 cases. The success rate of follow-up was 97.64%, and the loss of follow-up rate was 2.36%. The average age of onset was 56.67±12.78 years. The median survival time was 6.54 years, and the 1-, 3-, 5-, and 10-year observed survival rates were 91.50%, 76.95%, 60.99%, and 28.51%, respectively. Among the age groups, significant differences in survival rate were observed between the 15- and 60-year-old groups (χ²=7.469, P=0.006) and between the 15- and 80-year-old groups (χ²=36.317, P < 0.001). No significant difference in survival rate was found between patients from Haimen and Qidong (χ²=2.779, P=0.095) and between patients from Qidong and Tongzhou (χ²=0.515, P=0.473). Significant difference in survival rate was observed among other regions (P < 0.05). Conclusion In this study group, the survival rates of hospital-based patients with cervical cancer significantly differ among the age groups and regions of origin and significantly decreased with age. The high follow-up rate fully reflects the comprehensive effect of the treatment in Nantong Cancer Hospital for registered patients with cervical cancer in Nantong.

The 2-(2-phenylethyl)chromones were separated from agarwood of Aquilaria agallocha Roxb. and their anti-KRAS mutant non-small cell lung cancer (NSCLC) activities were evaluated. 2-(2-Phenyethyl)chromones in agarwood were separated and purified by silica gel, RP-18 reverse phase silica gel, MCI gel CH20P, Diol, and semi preparative HPLC chromatography techniques, while the structures of the compounds were identified by extensive spectroscopic analysis, such as 1D and 2D NMR and ESI-MS. The cell counting kit 8 (CCK-8) assay was used to screen the anti-tumor activity of the isolated monomeric compounds on three KRAS-mutant NSCLC cells. The cell proliferation, cloning formation, adhesion ability, and cell cycle arrest activity of compound 8 were analyzed. Molecular docking and Western blot experiments were used to study the mechanism of compound 8. The in vivo anti-tumor activity of the compound 8 was evaluated by zebrafish cell derived xenograft (CDX) model. Nineteen known 2-(2-phenylethyl)chromones were isolated from the ethyl acetate extract of agarwood. On A549 (KRAS G12S) cells, compounds 8, 10, and 19 showed good inhibitory activity, on H23 (KRAS G12C) cells, compounds 7, 8, and 19 showed good inhibitory activity, and on H358 (KRAS G12C) cells, compounds 8, 10, and 16 showed good inhibitory activity. Compound 8 had the best inhibitory activity in all three cell lines. It effectively inhibited cell proliferation, clone formation, adhesion ability, and arrested the H23 cell cycle at G2/M phase. Compound 8 could also inhibit the expression of c-Met and its downstream signaling pathways, effectively inhibiting tumor growth in zebrafish CDX model. In conclusion, among the nineteen known 2-(2-phenylethyl)chromones, compound 8 had the best activity and significantly inhibited the proliferation of KRAS-mutant NSCLC cells by arresting the cells in the G2/M phase.

Objective To understand the infectious pathogen characteristics and drug sensitivity of hospitalized patients in the respiratory intensive care unit (RICU) of Renmin Hospital of Wuhan University. Methods Bacterial culture samples sent to the RICU of our hospital from January 2020 to December 2022 were retrospectively analyzed. The bacterial types were identified by Bruker mass spectrometer, and the Phoenix 100 was used for drug sensitivity analysis. The antimicrobial susceptibility was analyzed by WHONET 5.6 software. Results A total of 1 157 strains of bacteria were isolated, including 878 strains of Gram-negative bacteria (75.89%) and 279 strains of Gram-positive bacteria (24.11%). The top five with the highest detection rate were Acinetobacter baumannii (25.50%), Pseudomonas aeruginosa (18.76%), Klebsiella pneumoniae (13.83%), Staphylococcus aureus (6.57%) and Escherichia coli (5.70%). Among them, Acinetobacter baumannii was extremely drug-resistant, only showing relatively high sensitivity to colistin, minocycline, and tigecycline. Staphylococcus aureus accounted for the highest proportion of Gram-positive bacteria (6.57%), with methicillin-resistant Staphylococcus (MRSA) showing a continuous increase. Conclusion In the past three years, Gram-negative bacteria have been the main pathogenic bacteria detected in the respiratory intensive care unit of our hospital. The main bacteria are Acinetobacter baumannii, Pseudomonas aeruginosa, and Klebsiella pneumoniae, which have a high resistance rate to various antibiotics. Therefore, clinical monitoring of resistant strains in RICU should be strengthened to facilitate rational use of antibiotics and improve antibacterial effect.

ObjectiveTo analyze and determine the differential components of freeze-dried and sun-dried Panacis Quinquefolii Radix（PQR）， and to compare the differences in their pro-angiogenic activities. MethodFingerprints of freeze-dried and sun-dried PQR were established based on ultra performance liquid chromatography（UPLC）， and chemometrics methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were combined to determine the differential saponin composition of the two decoction pieces， and six representative saponins were selected and their contents in freeze-dried and sun-dried PQR were determined by UPLC. Transgenic zebrafish line Tg（fli1a∶EGFP） embryos fertilized for 24 h were selected， and different doses of 70% methanol extracts of freeze-dried and sun-dried PQR（10， 30 mg·L^-1） were used to intervene in normal zebrafish and in a zebrafish model of intersegmental vascular（ISV） injury induced by vascular endothelial growth factor（VEGF） receptor tyrosine kinase inhibitor Ⅱ（PTK787）， then the development of subintestinal vein（SIV） and ISV of zebrafish was observed， SIV diameter， mean number of crossings and mean number of germinations were determined， and the ISV vascular index was calculated， in order to compare the pro-angiogenic activities of the two decoction pieces. ResultThe similarity of the fingerprints of freeze-dried and sun-dried PQR decoction pieces was>0.950， and 17 common peaks were identified， of which 6 common peaks were designated as peak 6（ginsenoside Rg₁）， peak 7（ginsenoside Re）， peak 8（ginsenoside Rb₁）， peak 11（ginsenoside Rc）， peak 13（ginsenoside Rb₂）， and peak 16（ginsenoside Rd）， respectively. A total of 11 differential saponin components were screened by PCA and OPLS-DA， indicating that there were some differences in the contents of the components in the two decoction pieces. The results of determination showed that the contents of ginsenosides Rg₁， Re， Rb₁ and Rb₂ in freeze-dried PQR were higher than those in sun-dried PQR， while the contents of ginsenosides Rc and Rd were lower than those in sun-dried PQR（P<0.05， P<0.01）. In the study of the pro-angiogenic effect on normal zebrafish embryos， compared with the blank group， and the SIV vessel diameter， mean germination rate and mean crossover rate were significantly higher in the high-dose groups of freeze-dried and sun-dried PQR（P<0.01）， and the vessel diameter， mean numbers of crossings and germinations in the freeze-dried PQR group were higher than those of the sun-dried PQR group（P<0.05）. In the study of the pro-angiogenic effect on zebrafish embryos with ISV injury， the development of ISV in the model group was significantly inhibited when compared with the blank group， compared with the model group， different dose groups of freeze-dried and sun-dried PQR could promote the growth and sprouting of ISV， and the number of normal blood vessels in the freeze-dried PQR group was significantly higher than that in the sun-dried PQR group at the same dosage（P<0.05）. ConclusionFreeze-drying can effectively avoid the loss and secondary transformation of ginsenosides in PQR， and its angiogenic activity is better than that of sun-dried PQR， which can provide a reference for the production and development of high-quality PQR decoction pieces.

Purpose To investigate the ultrasound imaging characteristics of Xp11.2 translocation/TFE3 gene fusion renal cell carcinoma(Xp11.2/TFE3-tRCC).Materials and Methods A retrospective analysis was conducted of 10 patients with pathologically confirmed Xp11.2/TFE3-tRCC who underwent surgery in West China Hospital of Sichuan University from April 2009 to February 2022.The ultrasonic images were collected and further analyzed,including tumor border,shape,internal echoes,Doppler findings,and contrast-enhanced ultrasonography findings.Results A total of 10 masses were finally included,4 of which underwent contrast-enhanced ultrasound.The ultrasonographic manifestations of Xp11.2/TFE3-tRCC showed diversity and variability,and the mass was most commonly located in the medulla(5 cases).Conventional ultrasound showed solid nodules with clear boundaries and regular shape similar to benign lesions in 6 cases,and color Doppler showed punctated blood flow signals in 5 cases.Contrast-enhanced ultrasound was more inclined to malignant tumors(3 cases),which showed uneven enhancement,mostly accompanied by peripheral uneven enhancement rings.Conclusion Xp11.2/TFE3-tRCC tends to be benign on conventional ultrasound,while contrast-enhanced ultrasound shows malignant lesions.Therefore,contrast enhanced ultrasound can serve as a potential diagnostic tool for suspected Xp11.2/TFE3-tRCC.

Objective:To investigate the efficacy and safety of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis.Methods:A retrospective analysis was carried out on 46 patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis who received endovascular treatment at the Strategic Support Force Medical Center from January 2015 to August 2022. Twenty-seven patients underwent balloon angioplasty alone and 19 patients underwent acute stent implantation. The baseline characteristics, modified thrombolysis in cerebral infarction (mTICI) score of the responsible vessels, modified Rankin scale (mRS) score 90 days after operation, incidence of symptomatic intracranial hemorrhage and mortality of the two groups were evaluated.Results:The proportion of effective recanalization of the offending vessels (mTICI≥2b) in the acute stenting group was slightly higher than that in the balloon angioplasty group (16/19 vs. 81.5%), but the difference was not statistically significant ( P>0.05). Besides, there was no significant difference in the median of mRS between the acute stenting group [3.0(0, 4.0)] and the balloon angioplasty group [4.0(1.0, 5.0)] 90 days after operation ( P>0.05). In terms of safety, the incidence of symptomatic intracranial hemorrhage and mortality were comparable between the two groups ( P>0.05). Conclusions:The effect of acute stent implantation during endovascular treatment for patients with emergent large vessel occlusion due to intracranial atherosclerotic stenosis is not inferior to that of balloon angioplasty, and it does not increase the risk of intracranial bleeding complications.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.
