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.

Asthma is a chronic inflammatory disease involving multiple inflammatory cells and cytokines. Its pathogenesis is complex, involving various cells and cytokines. Traditional Chinese medicine(TCM) theory suggests that the pathogenesis of asthma is closely related to the dysfunction of internal organs such as the lungs, spleen, and kidneys. In contrast, modern immunological studies have revealed the central role of T helper 1(Th1)/T helper 2(Th2) and T helper 17(Th17)/regulatory T(Treg) cellular immune imbalance in the pathogenesis of asthma. Th1/Th2 imbalance is manifested as hyperfunction of Th2 cells, which promotes the synthesis of immunoglobulin E(IgE) and the activation of eosinophil granulocytes, leading to airway hyperresponsiveness and inflammation.Meanwhile, Th17/Treg imbalance exacerbates the inflammatory response in the airways, further contributing to asthma pathology.Currently, therapeutic strategies for asthma are actively exploring potential targets for regulating the balance of Th1/Th2 and Th17/Treg immune responses. These targets include cytokines, transcription factors, key proteins, and non-coding RNAs. Precisely regulating the expression and function of these targets can effectively modulate the activation and differentiation of immune cells. In recent years,traditional Chinese medicine active ingredients have shown unique potential and prospects in the field of asthma treatment. Based on this, the present study systematically summarizes the efficacy and specific mechanisms of TCM active ingredients in treating asthma by regulating Th1/Th2 and Th17/Treg immune balance through literature review and analysis. These active ingredients, including flavonoids, terpenoids, polysaccharides, alkaloids, and phenolic acids, exert their effects through various mechanisms, such as inhibiting the activation of inflammatory cells, reducing the release of cytokines, and promoting the normal differentiation of immune cells. This study aims to provide a solid foundation for the widespread application and in-depth development of TCM in asthma treatment and to offer new ideas for clinical research and drug development of asthma.

Pelvic organ prolapse (POP), whose etiology is influenced by genetic and clinical risk factors, considerably impacts women's quality of life. However, the genetic underpinnings in non-European populations and comprehensive risk models integrating genetic and clinical factors remain underexplored. This study constructed the first polygenic risk score (PRS) for POP in the Chinese population by utilizing 20 disease-associated variants from the largest existing genome-wide association study. We analyzed a discovery cohort of 576 cases and 623 controls and a validation cohort of 264 cases and 200 controls. Results showed that the case group exhibited a significantly higher PRS than the control group. Moreover, the odds ratio of the top 10% risk group was 2.6 times higher than that of the bottom 10%. A high PRS was significantly correlated with POP occurrence in women older than 50 years old and in those with one or no childbirths. As far as we know, the integrated prediction model, which combined PRS and clinical risk factors, demonstrated better predictive accuracy than other existing PRS models. This combined risk assessment model serves as a robust tool for POP risk prediction and stratification, thereby offering insights into individualized preventive measures and treatment strategies in future clinical practice.

Objective To develop a matrix metalloproteinase(MMP)-responsive hyaluronic acid(HA)-based controlled-release material for brain-derived neurotrophic factor(BDNF)to provide a novel therapeutic strategy for intervention and repair of traumatic brain injury(TBI).Methods HA was modified with amination,followed by condensation with Suflo-SMCC carboxyl group to form amide,and then linked with glutathione(GSH)to synthesize HA-GSH.The recombinant glutathione S-transferase(GST)-tissue inhibitor of metalloproteinase(TIMP)-BDNF(GST-TIMP-BDNF)expression plasmid was constructed using molecular cloning technique with double enzyme digestion by Bam H Ⅰ and Eco R Ⅰ.The recombinant GST-TIMP-BDNF protein was expressed in the Escherichia coli prokaryotic expression system,and purified by ion exchange chromatography,confirmed by Western blotting.MMP diluents were supplemented with PBS,MMP inhibitor marimastat,and varing concentrations(0.4,0.6,0.8 mg/ml)of GST-TIMP-BDNF or GST-BDNF.MMP-2 activity was analyzed using an MMP activity detection kit to evaluate the inhibitory effect of the recombinant protein on MMP.Primary rat neurons were extracted and cultured to establish an iron death model induced by RSL3.The effect of recombinant protein GST-TIMP-BDNF on neuronal injury was detected by immunofluorescence staining.Results MRI hydrogen spectrum identification confirmed the successful synthesis of HA-GSH.Western blotting results showed the successful expression of the recombinant protein GST-TIMP-BDNF containing the GST tag using the E.coli prokaryotic expression system.MMP activity detection results indicated that the recombinant protein GST-TIMP-BDNF had a superior inhibitory effect on MMP-2 activity compared to GST-BDNF(P<0.05).Immunofluorescence staining results showed a significant increase in fluorescence intensity in rat neurons treated with GST-TIMP-BDNF after RSL3 induction(P<0.05).Conclusion A MMP-responsive HA-based BDNF controlled-release material has been successfully developed,exhibiting a protective effect on neuron damage.

Objective To investigate the risk factors for diabetic ketoacidosis(DKA)in children/adolescents with type 1 diabetes mellitus(T1DM)and to establish a model for predicting the risk of DKA.Methods A retrospective analysis was performed on 217 children/adolescents with T1DM who were admitted to General Hospital of Ningxia Medical University from January 2018 to December 2021.Among the 217 children/adolescents,169 cases with DKA were included as the DKA group and 48 cases without DKA were included as the non-DKA group.The risk factors for DKA in the children/adolescents with T1DM were analyzed,and a nomogram model was established for predicting the risk of DKA in children/adolescents with T1DM.Results For the 217 children/adolescents with T1DM,the incidence rate of DKA was 77.9%(169/217).The multivariate logistic regression analysis showed that high levels of random blood glucose,hemoglobin A1c(HbA1c),blood ketone body,and triglyceride on admission were closely associated with the development of DKA in the children/adolescents with T1DM(OR=1.156,3.203×1015,20.131,and 9.519 respectively;P<0.05).The nomogram prediction model had a C-statistic of 0.95,with a mean absolute error of 0.004 between the risk of DKA predicted by the nomogram model and the actual risk of DKA,indicating that the model had a good overall prediction ability.Conclusions High levels of random blood glucose,HbA1c,blood ketone body,and triglyceride on admission are closely associated with the development of DKA in children/adolescents with T1DM,and targeted intervention measures should be developed to reduce the risk of DKA.

Objective To explore the impact of nurse-led multidisciplinary collaborative nutrition inter-vention on the nutritional indicators in the patients with stroke.Methods A total of 100 patients with stroke admitted in this hospital from January to December 2020 were selected as the study subjects and divided into the observation group and control group by the propensity score matching,50 cases in each group.The control group was given the traditional nutrition intervention,and the observation group was given the nurse-led mul-tidisciplinary cooperative nutrition intervention.The blood,nutritional and biochemical indicators,physique monitoring indicators and nutritional risk indicators were compared between the two groups.Results The levels of total protein(TP),albumin(ALB),hemoglobin(Hb),prealbumin(PAB),body mass index(BMI),upper arm muscle circumference(AMC)and triceps skin fold thickness(TSF)on 21 d after admission in both groups were increased compared with those on 2,15 d after admission,and which on 15 d after admission were higher than those on 2 d after admission(P＜0.05),moreover the above indicators levels on 15,21 d after ad-mission in the observation group were higher than those in the control group,and the differences were statisti-cally significant(P＜0.05).Body mass index(BMI),upper arm circumference(AMC)and triceps skinfold thickness(TSF)in both groups on 21 d of admission were higher than those on 2,15 d of admission(P＜0.05).The nutritional risk screening 2002(NRS2002)score on 21 d after admission in the two groups were decreased compared with those on 2,15 d after admission,while which on 15 d after admission was decreased compared with that on 2 d after admission,moreover the NRS2002 score on 15,21 d after admission in the ob-servation group were lower than those in the control group,and the differences were statistically significant(P＜0.05).Conclusion Giving the nurse-led multidisciplinary cooperative nutrition intervention could im-prove the blood nutritional and biochemical indicators and physique monitoring indicators,and reduce the nu-tritional risk of the patients with stroke.

OBJECTIVE: Arsenic (As) and fluoride (F) are two of the most common elements contaminating groundwater resources. A growing number of studies have found that As and F can cause neurotoxicity in infants and children, leading to cognitive, learning, and memory impairments. However, early biomarkers of learning and memory impairment induced by As and/or F remain unclear. In the present study, the mechanisms by which As and/or F cause learning memory impairment are explored at the multi-omics level (microbiome and metabolome). METHODS: We stablished an SD rats model exposed to arsenic and/or fluoride from intrauterine to adult period. RESULTS: Arsenic and/fluoride exposed groups showed reduced neurobehavioral performance and lesions in the hippocampal CA1 region. 16S rRNA gene sequencing revealed that As and/or F exposure significantly altered the composition and diversity of the gut microbiome，featuring the Lachnospiraceae_NK4A136_group, Ruminococcus_1, Prevotellaceae_NK3B31_group, [Eubacterium]_xylanophilum_group. Metabolome analysis showed that As and/or F-induced learning and memory impairment may be related to tryptophan, lipoic acid, glutamate, gamma-aminobutyric acidergic (GABAergic) synapse, and arachidonic acid (AA) metabolism. The gut microbiota, metabolites, and learning memory indicators were significantly correlated. CONCLUSION Learning memory impairment triggered by As and/or F exposure may be mediated by different gut microbes and their associated metabolites.

Objective:To explore the application value of uterine artery blood flow ultrasound parameters in evaluating the prognosis of threatened abortion during early pregnancy.Methods:In this non-randomized controlled prospective clinical study, 108 women with threatened abortion during early pregnancy (6-12 weeks of pregnancy) who received treatment in the Health Community Group of Yuhuan Second People's Hospital from July 2021 to December 2022 were included in the observation group. An additional 108 healthy women who were at the early stage of pregnancy were selected for the control group. Color Doppler ultrasound was performed in both groups to measure the ultrasonic parameters of uterine artery blood flow (peak systolic/end diastolic flow velocity, resistance index, pulsatility index) and compare their differences. The pregnant women in the observation group were followed up until 28 weeks of gestation, and their prognosis was analyzed. The pregnant women who had successfully insured their babies were included in the good prognosis group, and the pregnant women who had aborted their babies were included in the poor prognosis group. The ultrasonic parameters of uterine artery blood flow in the two groups were compared. Logistic regression analysis was used to analyze the correlation between ultrasound parameters of uterine artery blood flow and poor prognosis.Results:In the observation group, the systolic peak/end diastolic flow velocity, resistance index, and pulsatility index on the left side were (6.46 ± 1.71), (0.97 ± 0.30), (2.72 ± 0.89), respectively, and they were (6.49 ± 1.70), (0.96 ± 0.32), (2.70 ± 0.91) respectively on the right side, which were significantly greater than (3.90 ± 1.02), (0.64 ± 0.17), (1.36 ± 0.54), (3.91 ± 1.04), (0.62 ± 0.18), (1.35 ± 0.52) in the control group ( t = 13.36, 9.95, 13.58, 13.45, 9.62, 13.39, all P < 0.001). Twenty-eight-week follow-up results showed that 72 women (66.67%) in the observation group had successfully insured their babies and 36 women (33.33%) had aborted their babies. In the good prognosis group, the systolic peak/end diastolic flow velocity, resistance index, and pulsatile index were (7.95 ± 1.89), (1.22 ± 0.36), (3.06 ± 0.95) on the left side, and they were (7.45 ± 1.94), (1.24 ± 0.37), and (3.03 ± 0.96) on the right side, which were significantly greater than (4.72 ± 1.27), (0.77 ± 0.24), (1.74 ± 0.69), (4.74 ± 1.32), (0.75 ± 0.25), (1.77 ± 0.70) in the poor prognosis group ( t = 10.53, 7.73, 8.23, 8.55, 8.14, 7.76, all P < 0.001). Logistic regression analysis showed that peak systolic/end diastolic flow velocity and resistance index were risk factors for poor prognosis of threatened abortion during early pregnancy, while the pulsatility index had no significant correlation with poor prognosis of threatened abortion during early pregnancy. Conclusion:Uterine artery blood flow ultrasound parameters have a certain predictive value for the prognosis evaluation of threatened abortion during early pregnancy, which can provide an important reference for clinical fetal protection treatment and benefit the prognosis of pregnant women.

OBJECTIVE: To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology, and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease. METHODS: Forty-five patients with chronic persistent asthma (observation group) and 45 healthy subjects (control group) were selected. The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) were measured by BK-MT02A medical infrared thermography. RESULTS: The body surface temperature of bilateral Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in the observation group was higher than that in the control group (P<0.01, P<0.05). The body surface temperature of bilateral Feishu (BL 13) and Geshu (BL 17) was higher than that of ipsilateral Pishu (BL 20) and Shenshu (BL 23) in the two groups (P<0.01, P<0.05). There was no statistically significant difference in body surface temperature between ipsilateral Feishu (BL 13) and Geshu (BL 17), between ipsilateral Pishu (BL 20) and Shenshu (BL 23) (P>0.05). CONCLUSION The pathological increase of body surface temperature of Feishu (BL 13), Geshu (BL 17), Pishu (BL 20) and Shenshu (BL 23) in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases. The Feishu (BL 13) and Geshu (BL 17), which have significantly increased body surface temperature, not only provide objective basis for the pathological pathogenesis of "deficiency in origin and excess in symptom" in patients with chronic persistent asthma, but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.
