Elemene is widely recognized as an effective anti-cancer compound and is routinely administered in Chinese clinical settings for the management of several solid tumors, including non-small cell lung cancer (NSCLC). However, its detailed molecular mechanism has not been adequately demonstrated. In this research, it was demonstrated that elemene effectively curtailed NSCLC growth in the patient-derived xenograft (PDX) model. Mechanistically, employing high-throughput screening techniques and subsequent biochemical validations such as microscale thermophoresis (MST), microRNA-145-5p (miR-145-5p) was pinpointed as a critical target through which elemene exerts its anti-tumor effects. Interestingly, elemene serves as a binding stabilizer for miR-145-5p, demonstrating a strong binding affinity (dissociation constant (K _D) = 0.39 ± 0.17 μg/mL) and preventing its degradation both in vitro and in vivo, while not interfering with the synthesis of the primary microRNA transcripts (pri-miRNAs) and precursor miRNAs (pre-miRNAs). The stabilization of miR-145-5p by elemene resulted in an increased level of this miRNA, subsequently suppressing NSCLC progression through the miR-145-5p/mitogen-activated protein kinase kinase kinase 3 (MAP3K3)/nuclear factor kappaB (NF-κB) pathway. Our findings provide a new perspective on revealing the interaction patterns between clinical anti-tumor drugs and miRNAs.

ObjectiveTo investigate the prevalence of stroke in Songjiang District from 2017 to 2022, to analyze the epidemiological characteristics of stroke incidence, so as to provide a scientific basis for the formulation of stroke prevention and control policies. MethodsData of new stroke incidence from 2017 to 2022 in Songjiang District were obtained from the Shanghai Stroke and Acute Myocardial Infarction Registration and Reporting Information System. In addition, different classifications such as time of onset, gender, age group and types of stroke, were statistically analyzed. Statistical indicators, such as the number of incidence, crude incidence rate, standardized incidence rate and average age of incidence were calculated simultaneously. Joinpoint software were used to calculate the annual change percentage (APC) and the trend of stroke incidence in Songjiang District. ResultsFrom 2017 to 2022, the newly reported cases of stroke were 12 988 in Songjiang District, the crude incidence rate was 325.76/10⁵, and the standardized incidence rate was 127.58/10⁵. The crude incidence rate and standardized incidence rate in males were 363.45/10⁵ and 157.17/10⁵, respectively, but 288.68/10⁵ and 99.02/10⁵ in females. The mean age of onset was (73.12±11.75) years, of which the mean age of onset was (70.86±11.96) years for men and (75.91±10.85) years for women. The incidence of stroke increased with age, rising rapidly after 60 years and reaching a peak in the age group of ≥ 80 years old. The crude incidence rate and standardized incidence rate of stroke in Songjiang District showed a downward trend from 2017 to 2022, with an APC of -6.20% and -8.01%, respectively (P=0.018, 0.007). The newly reported stroke was dominated by ischemic stroke, accounting for 82.81% of the total cases, with a crude incidence rate of 269.77/10⁵ and a standardized rate of 103.84/10⁵. The incidence of stroke presented seasonal characteristics, with the highest incidence in winter, accounting for 26.11% of the whole year. ConclusionThe incidence rate of stroke in Songjiang District shows a declined trend, but the overall incidence is still at a high level. The situation of prevention and control is still serious, with a heavy disease burden. It is necessary to strengthen health education and disease management for the elderly.

ObjectiveTo investigate the high-risk detection rate and aggregation of cardiovascular diseases（CVD） in 8 districts of Shanghai and influencing factors， and to provide scientific references for prevention and control of CVD. MethodsBased on the Cardiovascular Disease Screening and Management Program in Shanghai from 2016 to 2021， 104 685 participants aged 35 to 75 in 8 districts of Shanghai were selected for analysis. χ² test and multivariate logistic regression were used for statistical analysis of the influencing factors of CVD and aggregation of CVD. ResultsThe proportion of high-risk CVD individuals in the population was 19.17%， including the high-risk individuals with hypertension （8.65%）， dyslipidemia （6.33%）， CVD history （5.58%）， and WHO assessed risk ≥20% types （2.69%）， respectively. Old age， overweight and obesity， central obesity， smoking， drinking， farmers， unmarried， and low family income were the risk factors of CVD， while high education level was the protective factor. In the participants， 16 323 people （81.34%） were classified as CVD high-risk groups； The number of aggregation of 1， 2 and ≥3 high risk types of CVD were 16 323（81.34%）， 3 236（16.13%）， 509（2.54%）， respectively. Old age， low education level， low annual family income， farmers， unmarried， smoking， drinking， overweight， obesity and central obesity were associated with the risk of aggregation of high risk types of CVD， and the correlation strength increased with the increase of aggregation types. ConclusionThe prevention and control of CVD in Shanghai should focus on the hypertension， elderly， overweight， obesity， central obesity， smoking， drinking， low educated， low family income， farmers and unmarried people， and targeted intervention measures should be taken to reduce the risk of CVD among residents.

Objective To develop a questionnaire on the transitional care needs of patients undergoing arthroscopic day surgery and to test its reliability and validity.Methods Based on the Omaha Question Classification System,the questionnaire item pool was constructed after literature reviews and qualitative interviews.A questionnaire-based scale was drafted based on the established item pool by carrying out two rounds of consultation with 15 experts in clinical nursing,nursing management,clinical medicine,rehabilitation medicine,and other fields from 6 provinces or cities in China.Reliability and validity of the scale were tested using convenience sampling,involving 280 patients with arthroscopic day surgery from 4 general hospitals in Jinan of Shandong province,China,between March and August 2023.Results The response rates for the two rounds of expert consultation were 83.33%and 100.00%,respectively.The authority coefficients of the two rounds both was 0.82,and the coordination coefficients for the 2 rounds were 0.169 and 0.218,respectively.In the first round,the average importance rating of secondary index was from 4.13 to 4.80 with the coefficient of variation from 0.086 to 0.208,and the full score ratio from 33.33%to 80.00%.In the second round,the average importance rating of secondary index ranged from 4.20 to 5.00 with the coefficient of variation from 0.00 to 0.18,and the full score ratios from 40%to 100.00%.A total of 280 patients completed the survey.The overall Cronbach's α coefficient of the scale was 0.922,the overall split-half reliability was 0.79,the scale-level content validity index(S-CVI)and the item-level content validity index(I-CVI)of the total scale all was 1.The KMO value of exploratory factor analysis was 0.925,the Bartrett spherical test value was 5456.320(P<0.001),and the cumulative variance contribution rate was 63.319%.After the reliability and validity tests,the scale was finalised and determined to consist of four dimensions with 30 items:environmental field(2 items),psychosocial field(5 items),physiological field(15 items)and health-related behavior field(8 items).Conclusion The questionnaire on the transitional care needs of patients undergoing arthroscopic day surgery has good reliability and validity and makes it an effective assessment tool for the transitional care need of arthroscopic day surgery patients.

OBJECTIVES: To investigate the effect of recombinant human fibroblast growth factor 21 (rhFGF21) on the proliferation and mineralization of cementoblasts and its mechanism. METHODS: Hematoxylin eosin, immunohistochemical staining, and immunofluorescence were used to detect the expression and distribution of fibroblast growth factor 21 (FGF21) in rat periodontal tissues and cementoblasts (OCCM-30), separately. Cell Counting Kit-8 was used to detect the proliferation of OCCM-30 under treatment with rhFGF21. Alkaline phosphatase staining and Alizarin Red staining were used to detect the mineralization state of OCCM-30 after 3 and 7 days of mineralization induction. The transcription and protein expression of the osteogenic-related genes Runx2 and Osterix were detected by real-time quantitative polymerase chain reaction (PCR) and Western blot analysis. The expression levels of genes of transforming growth factor β (TGFβ)/bone morphogenetic protein (BMP) signaling pathway in OCCM-30 were detected through PCR array analysis. RESULTS: FGF21 was expressed in rat periodontal tissues and OCCM-30. Although rhFGF21 had no significant effect on the proliferation of OCCM-30, treatment with 50 ng/mL rhFGF21 could promote the mineralization of OCCM-30 cells after 7 days of mineralization induction. The transcriptional levels of Runx2 and Osterix increased significantly at 3 days of mineralization induction and decreased at 5 days of mineralization induction. Western blot analysis showed that the protein expression levels of Runx2 and Osterix increased during mineralization induction. rhFGF21 up-regulated Bmpr1b protein expression in cells. CONCLUSIONS rhFGF21 can promote the mineralization ability of OCCM-30. This effect is related to the activation of the TGFβ/BMP signaling pathway.

Chronic heart failure (CHF) is a severe public health problem with increasing morbidity and mortality, any treatment targeting a single session is insufficient to tackle this. CHF is characterized by reduced cardiac output resulting from neurohumoral dysregulation and cardiac remodeling, which might be related to oxidative stress, inflammation, endoplasmic reticulum stress, apoptosis, autophagy, mitochondrial function, and angiogenesis. These molecular mechanisms interact with each other through crosstalk. Historically, Chinese medicinal herbs have been widely applied in the treatment of CHF, and therapeutic effects of Chinese medicinal herbs and their ingredients have been scientifically confirmed over the past decades. Traditional Chinese medicine (TCM) with multiple components can confront the different pathogenesis of CHF through multiple targets. This review analyzes commonly used TCM patent drugs and TCM decoctions that are applicable to different stages of CHF based on clinical trials. Diverse bioactive ingredients in Chinese medicinal herbs have been found to treat CHF via multiple molecular mechanisms. This review comprehensively covers the key works on the effects and underlying mechanisms of TCM, herbal ingredients and synergistic effects of constituent compatibility in treating CHF, providing additional ideas to address this threat.

Objective To investigate the influence of collateral circulation recruitment on cognitive functions in patients with severe unilateral stenosis or unilateral occlusion of the internal carotid artery by using TCD.Methods A total of 176 patients with severe unilateral stenosis or unilateral occlusion of the internal carotid artery were enrolled and were divided into a single vessel collateral group(n=80,45.5 ％),a multiple vessel collateral group(n=74,42.1％) and a no collateral group(n=22,12.5 ％).In order to study the influence of single vessel collateral circulation on cognitive functions,the single vessel collateral group was further divided into an anterior communicating subgroup(AcoA),a posterior communicating subgroup(PcoA),an ocular artery subgroup(OA),and a normal control subgroup.All patients and 34 normal controls(NC) received MoCA,and scores for the overall assessment and individual domains were analyzed.Results Compared with the control group (26.3± 1.1,4.7 ± 0.5,2.0 ± 0.0,3.6 ± 1.0),the multiple vessel collateral group,the single vessel collateral group and the no collateral group had lower overall scores (24.2 ± 1.7,21.9 ± 2.3,19.0 ± 2.4),lower executive/visuospatial function(3.9 ± 0.7,3.2 ± 0.8,2.4 ± 0.6),lower abstraction (1.7 ± 0.5,1.6±0.5,1.3±0.5),and lower delayed recall(2.9±0.8,1.9±0.8,1.6±0.5)(F=80.52,63.21,12,48.99,all P＜0.05);both collateral groups had lower scores in subtraction and attention (4.6±0.6 vs.5.2±0.7,4.3±0.7 vs.5.2±0.7);the no collateral group had lower scores in orientation(4.7±0.7 vs.5.7±0.5)(P＜0.05).Compared with the multiple vessel collateral group,both the single vessel collateral group and the no collateral group had lower overall scores(21.9±2.3 vs.24.2 ± 1.7,19.0± 2.4 vs.24.2 ± 1.7),executive/visuospatial function (3.2 ± 0.8 vs.3.9 ± 0.7,2.4±0.6 vs.3.9±0.7),subtraction and attention(4.6±0.6 vs.5.1±0.5,4.3±0.7 vs.5.1±0.5) (all P＜ 0.05);the no collateral group had lower scores in abstraction (1.3 ± 0.5 vs.1.7 ± 0.5),delayed recall(1.6 ± 0.5 vs.2.9 ± 0.8) and orientation (4.7 ± 0.7 vs.5.7 ± 0.5) (all P ＜ 0.05).Compared with the single vessel collateral group,the no collateral group had lower overall scores(19.0 ±2.4 vs.21.9±2.3),executive/visuospatial function(2.4±0.6 vs.3.2±0.8)and orientation(4.7± 0.7 vs.5.7 ± 0.6) (all P ＜0.05).In single vessel collateral patients,the AcoA subgroup had higher MoCAscores than the PcoA subgroup(22.9± 1.7 vs.21.2±2.7) (P＜0.05),and the AcoA subgroup had higher scores in delayed recall than the OA subgroup(2.2±0.8 vs.1.7±0.6) (P＜ 0.05).Conclusions Severe unilateral stenosis or unilateral occlusion in the internal carotid artery can result in cognitive impairment,especially in executive/visuospatial function,abstraction,delayed recall,subtraction and attention.However,collateral circulation can protect cognitive function in patients with unilateral internal carotid artery stenosis or occlusion and multiple vessel collateral circulation is more effective than single vessel collateral circulation,and AcoA is more effective than either PcoA or OA,but the difference between PcoA and OA is not significant.
