Objective To prepare a nano drug(PFOB@Lip-MMC)with liposome as the carrier,liquid perfluorooc-tyl bromide(PFOB)as core and mitomycin C(MMC)loading on the liposome shell and study its inhibitory effect on the proliferation of human pterygium fibroblasts(HPFs).Methods The thin film dispersion-hydration ultrasonic method was used to prepare PFOB@Lip-MMC and detect its physical and chemical properties.Cell Counting Kit-8,Cam-PI cell viability staining and flow cytometry were employed to detect the impact of different concentrations of PFOB@Lip-MMC on the via-bility of HPFs.DiI fluorescence labeled PFOB@Lip-MMC was used to observe the permeability of the nano drug to HPFs under a laser confocal microscope.After establishing HPF inflammatory cell models,they were divided into the control group(with sterile phosphate-buffered saline solution added),PFOB@Lip group(with PFOB@Lip added),MMC group(with MMC added),PFOB@Lip-MMC group(with PFOB@Lip-MMC added)and normal group(with fresh culture medi-um added)according to the experimental requirements.After co-incubation for 24 h,flow cytometer was used to detect the apoptosis rate of inflammatory cells,and the gene expression levels of interleukin(IL)-1β,prostaglandin E2(PGE2),tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF)in cells were analyzed by PCR.Results The average particle size and Zeta potential of PFOB@Lip-MMC were(103.45±2.17)nm and(27.34±1.03)mV,respec-tively,and its entrapped efficiency and drug loading rate were(72.85±3.28)％and(34.27±2.04)％,respectively.The sustained-release MMC of drug-loaded nanospheres reached(78.34±2.92)％in vitro in a 24-hour ocular surface environ-ment.The biological safety of PFOB@Lip-MMC significantly improved compared to MMC.In terms of the DiI fluorescence labeled PFOB@Lip-MMC,after co-incubation with inflammatory HPFs for 2 h,DiI fluorescence labeling was diffusely dis-tributed in the cytoplasm of inflammatory HPFs.The apoptosis rate of inflammatory HPFs in the PFOB@Lip-MMC group[(77.23±4.93)％]was significantly higher than that in the MMC group[(51.62±3.28)％].The PCR examination results showed that the gene transcription levels of IL-1 β,PGE2,TNF-α and VEGF in other groups were significantly reduced com-pared to the control group and PFOB@Lip group,with the most significant decrease in the PFOB@Lip-MMC group(all P＜0.05).Conclusion In this study,a novel nano drug(PFOB@LIP-MMC)that inhibited the proliferation of HPFs was successfully synthesized,and its cytotoxicity was significantly reduced compared to the original drugs.It has good bio-compatibility and anti-inflammatory effects,providing a new treatment approach for reducing the recurrence rate after pte-rygium surgery.

Objective: To determine the efficacy and safety of the Yinmei Kuijie decoction combined with 5-aminosalicylic acid (5-ASA) in treating mildly to moderately active ulcerative colitis (UC) under real-world conditions. Methods: This multicenter, prospective, non-randomized, observational study will be conducted in real-world settings. A total of 204 eligible patients will be consecutively enrolled in the study. Patients in the combination treatment group will receive Yinmei Kuijie decoction in combination with 5-ASA, whereas those in the control group will be treated with 5-ASA alone. The primary endpoint will be a clinical response at week 12, defined as a ≥3 point and ≥30% reduction from baseline in the Mayo total score with ≥1 reduction in rectal bleeding or rectal bleeding score = 0 or 1. Secondary efficacy endpoints at week 12 will include health-related quality of life, mucosal healing, and inflammation indicators. Conclusion The results of this study may provide evidence of the efficacy and safety of Yinmei Kuijie decoction combined with 5-ASA in treating patients with mildly to moderately active UC under real-world principles. The results will provide a basis for further confirmatory studies on the efficacy of Yinmei Kuijie decoction.

BACKGROUND/OBJECTIVES: The specific impact of different fruit and vegetable consumption categories on frailty is not completely understood. This study examined the relationships between the daily consumption of fruit and vegetables and frailty in a large general population. SUBJECTS/METHODS: This study used the data from the US National Health and Nutrition Examination Survey (2005–2020). Two intermittent 24-h dietary recalls were used to evaluate fruit and vegetable consumption. Frailty was assessed using the frailty index. Logistic regression, stratified analyses, and restricted cubic spline models were used to examine these associations. RESULTS: A higher daily intake of citrus, melons, and berries (odds ratio [OR], 0.77; 95% confidence interval [CI], 0.65–0.92), other fruit (OR, 0.74; 95% CI, 0.62–0.88), intact fruit (OR, 0.71; 95% CI, 0.60–0.84), dark-green vegetables (OR, 0.71; 95% CI, 0.60–0.83), and total vegetables (OR, 0.80; 95% CI, 0.66–0.96), along with a lower fruit juice intake (OR, 0.81; 95% CI, 0.69–0.96), were associated with a reduced risk of frailty in adults aged 18 yrs and older.Further analysis showed that the daily consumption of citrus melons and berries, other fruit, intact fruit, fruit juice, and tomatoes and tomato products were inversely associated with frailty in adults under 60 yrs and females. Dark green vegetables were inversely correlated with frailty in individuals aged 40–60 yrs and over 60 yrs, regardless of sex. CONCLUSION The daily consumption of most types of fruit, dark green vegetables, and tomatoes and tomato products may reduce the risk of frailty in American adults, particularly for individuals under 60 yrs of age and females.

Abstract OBJECTIVE To establish an efficient and simple HPLC-MS/MS method for determination of flucloxacillin in newborn plasma, and to investigate the interaction between ambroxol and flucloxacillin in newborns. METHODS The samples were analyzed by API4000 HPLC-MS/MS. Ultimate XB-C18 column(2.1 mm×100 mm, 5 μm) were carried out. The mobile phase was composed of water-0.1% formic acid(A) and acetonitrile-0.1% formic acid(B). The quantitative analysis of the ion transitions were monitored at m/z 452.6→284.2 for flucloxacillin and m/z 821.4→397.3 for rifampicin(internal standard). RESULTS The linear range of flucloxacillin under this analysis method was 0.20-80 ng·mL-1, and the lower limit of quantification was 0.20 ng·mL-1; The intra-day and inter-day precision of flucloxacillin were both less than 8.23%; The extraction recovery was in the range of 85.3%-89.2%, and the matrix effect was between 89.3%-92.3%; The stability of plasma samples was good under conditions of 12 h at room temperature, 4 h at room temperature after treatment, repeated freeze-thaw for 3 times, and -20 ℃ freezing for 30 d. The results of clinical samples indicated that the combination of ambroxol could significantly increase the blood concentration of flucloxacillin. CONCLUSION The established HPLC-MS/MS method is accurate, sensitive and can be used for the determination of flucloxacillin concentration in neonatal plasma. The results of clinical samples indicate that ambroxol can significantly increase the blood concentration of flucloxacillin. There are drug interactions between ambroxol and flucloxacillin.

Epilepsy is a common chronic neurological disease, and its comorbidity has attracted more attention.The proportion of epileptic children with mental disorders is also increasing year by year.Among them, children with epilepsy have more depression and anxiety disorders.Repeated seizures can easily cause depression and anxiety, and depression and anxiety can also induce epilepsy, thus the two affect each other.The assessment, screening, diagnosis and intervention of comorbid depression and anxiety in children with epilepsy have become an important part of clinical practice.This review summarized the relationship between epilepsy and depression and anxiety disorders in children, and its research progress on pathogenesis, clinical diagnosis, evaluation and treatment.

Objective:To observe the construction of mobile health management model for elderly patients with coronary heart disease, and to conduct empirical research.Methods:A total of 86 elderly patients with coronary heart disease treated in Henan Provincial People's Hospital from January 2019 to January 2021 were selected.They were randomly divided into 2 groups: the control group receiving routine intervention(n=43), and the observation group receiving mobile health management mode as an add-on to routine interventions(n=43).After 3 months of intervention in control versus observation groups, angina, readmission risk factors were assessed, and status of target criteria for low-density lipoprotein cholesterol(LDL-C), resting heart rate, systolic, and diastolic blood pressure as readmission risk factors were evaluated.Before and 3 months after intervention, the self-care ability of patients was evaluated.Results:Number of angina pectoris attacks was less in observation(0.53±0.18)than in control group(0.64±0.15)( t=3.079, P=0.003).Duration of the angina pectoris was shorter in observation(2.72±0.40)min than in control group(3.06±0.55)min, ( t=3.278, P=0.002).Rate of achieving effectiveness of indicators for the risk factors of readmission was higher in observation group than in control group as following data: LDL-C(90.7% and 72.1%, χ2=4.914, P=0.027), resting heart rate(95.4% and 81.4%, χ2=4.074, P=0.044), systolic blood pressure(86.1% and 60.5%, χ2=7.182, P=0.007)and diastolic blood pressure(88.4% and 67.4%, χ2=5.472, P=0.019).The scores of self responsibility, health knowledge, self-care skills and self-concept were higher in the observation group than in the control group, with a statistical significant difference(all P<0.05). Conclusions:The construction of mobile health management model and its application in elderly patients with coronary heart disease are beneficial to improve the symptoms of angina pectoris, reduce the risk factors of readmission and improve the ability of self-care of patients.
