Objective:The components of Rubus parvifolius L. were analyzed based on UPLC-MS/MS technology and combined with network pharmacology analysis to explore the mechanism of action of Rubi Parvifolii Radix in treating inflammation, cough, fever, influenza and sore throat. Method:The chemical constituents of Rubi Parvifolii Radix were identified according to the information of mass spectrometry. The network pharmacology was used to analyze the corresponding targets and related pathways of its chemical components, and the "component-target-pathway" interaction diagram was drawn. PyMOL 2.5.7 software wasused to perform molecular docking between active components and key targets.Results:Twenty chemical components were identified by UPLC-MS/MS, and 15 components were screened out by network pharmacology, which can be used as quality markers of Rubi Parvifolii Radix, namely Azelaic acid, Procyanidol B3, Caprolactam, Bis (2-ethylhexyl) adipate, Cryptochlorogenic acid, 3-O-Feruloylquinic, Ellagic acid, Aurantiamide acetate, 2 α,3 β,19 α,23-Tetrahydroxyurs-12-en-28-oic acid, L-Epicatechin, (E)-3-Indoleacrylic acid, Euscaphic acid, Suberic acid, Diisononyl phthalate and Prodelphinidin T4. Molecular docking showed that 5 compounds compared with the reference substance could bind to the target proteins of disease well. Conclusions:The 15 active ingredients in Rubi Parvifolii Radix, including Caprolactam and (E)-3-Indoleacrylic acid, may play a therapeutic role in treating colds, high fever, sore throat, and inflammation by acting on targets such as AKT1 and TNF. This provides a certain reference for the clinical application of Rubi Parvifolii Radix.

Objective:To explore the association between the systemic immune-inflammation index (SII) and obesity metabolic phenotypes, as well as metabolic features in children and adolescents.Methods:A cross-sectional study was conducted using the random cluster sampling method from March 2023 to May 2024. Children and adolescents aged 9-17 years in Guangzhou were surveyed through questionnaires, physical measurements, and blood tests. According to BMI and metabolic status, participants were classified into normal-weight groups [metabolically healthy normal weight (MHNW) and metabolically unhealthy normal weight (MUNW)] and overweight/obese groups [metabolically healthy overweight/obese (MHO/O) and metabolically unhealthy overweight/obese (MUO/O)]. After natural log-transformation of SII values (lnSII), multinomial logistic regression was used to assess the association between SII and obesity metabolic phenotypes, while binary logistic regression was applied to assess the relationship between SII and metabolic phenotypes in the overweight/obese subgroup. Linear regression model and restricted cubic spline (RCS) were employed to examine the relationship between SII and metabolic features among the entire population.Results:A total of 3 749 participants were included. After adjusting for covariates, for every unit increase in lnSII, the risk of MHO/O and MUO/O increased by 93% ( OR=1.93, 95% CI: 1.56-2.40, P<0.001) and 156% ( OR=2.56, 95% CI: 2.02-3.25, P<0.001), respectively. In the overweight/obesity subgroup, for every unit increase in lnSII, the risk of MUO/O increased by 37% ( OR=1.37, 95% CI: 1.01-1.87, P=0.045). Linear regression model and RCS showed that lnSII was positively correlated with systolic blood pressure (SBP) and diastolic blood pressure (DBP) (SBP: β=1.39, 95% CI: 0.67-2.11, P<0.001; DBP: β=1.27, 95% CI: 0.79-1.75, P<0.001). lnSII also had a non-linear relationship with triglyceride ( Pnonlinear=0.032) and high-density lipoprotein cholesterol ( Pnonlinear=0.002). Conclusion:Elevated SII levels are associated with unfavorable obesity metabolic phenotypes, higher blood pressure, and altered lipid profiles in children and adolescents. SII may be a potential driving factor for metabolic heterogeneity in children and adolescents.

Objective:To explore the effect of ointment massage on the postoperative recovery of newborns who had intestinal tract operation, aim to construct an effective post-operative ointment and massage scheme and to enrich the content of enhanced recovery after surgery in the field of newborns.Methods:Delphi expert inquiry method was used to construct the ointment message scheme. A total of 64 newborns undergone intestinal surgery from May 2022 to May 2023 in Guangdong Women and Children Hospital were selected as study subjects and divided into routine group (34 cases) and ointment group (30 cases) by random number table method. In addition to routine treatment and nursing, the newborns in the ointment group also received ointment massage. The postoperative gastrointestinal drainage volume, fasting days, the first feeding time, hospital stay and the number of cases of vomiting and abdominal distension between the two groups were compared.Results:A total of 16 experts with (38.93 ± 5.13) years old were inquired, 6 males and 10 females. The effective questionnaire response rates for the two rounds of expert inquiry were 16/16 and 15/16, the expert authority coefficients were both≥0.80, the Kendall′s W coefficients were 0.117 and 0.107, with statistically significant differences (both P<0.05). A ointment message scheme consisting of 8 acupoints and 7 kinds of traditional Chinese medicines was determined. In the routine group, there were 19 males and 15 females with (268.47 ± 11.27) gestational age. In the ointment group, there were 20 males and 10 femles with (271.93 ± 10.36) gestational age. The postoperative gastrointestinal drainage volume, fasting days, the first feeding time and the hospital stay in the ointment group were 74.0 ml, 6.0 d, 158.5 h and 13.0 d, which had significant differences with the 184.5 ml, 7.5 d, 192.0 h, 16.5 d in the routine group ( Z values were 2.07-2.45, all P<0.05). The incidence of vomiting and abdominal distension in the ointment group were both 8 cases, which were lower than the 19 and 18 cases in the routine group with a statistically significant difference ( χ2 = 5.58, 4.56, both P<0.05). Conclusions:The ointment massage in this study has a positive impact on the recovery of newborn infants after intestinal surgery, with high safety, in line with enhanced recovery after surgery concept, and is worthy of promotion.

Objective To explore the humidification effects between the humidifiers Venturi high-flow oxygen therapy(HVHF)and the high-flow humidified oxygen therapy in the treatment of patients with tracheotomy after the withdrawal of ventilator,and analyse the humidification performance and effect of airway humidification on the two oxygen therapies hence to provide an objective basis for selection of a humidified oxygen therapy.Methods A total of 146 ICU patients who had tracheotomy and completely withdrawal of ventilator in a general hospital in Shenzhen from July 2020 to December 2021 were randomly divided into trial group(n=73)and control group(n=73).With identical speed of airflow,patients in the trial groups were treated with HVHF and the patients of control group were offered with high-flow humidified oxygen therapy via AIRVOTM2.Data of the two groups were compared at the time points of days 0,2,7 and 14 in terms of absolute humidity(AH),relative humidity(RH),temperature(T)),sputum viscosity,arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),oxygenation index(PaO2/FIO2)and the incidence of pulmonary infection.Results In the study,total of 61 patients in the control group and 72 patients in the trial group completed the high-flow humidified oxygen therapies,due to tubing detachments in 12 and 1 patients in the two groups,respectively.Repeated-Measures ANOVA analysis showed that,in both groups,there was a time effect(P<0.05)between the absolute humidity,relative humidity,temperature of the gas,PaO2,PaCO2,and PaO2/FiO2 at different time points.PaO2 and PaO2/FiO2 in both groups showed interactions at different time points(P<0.05).PaO2 and PaO2/FiO2 in the trial group were better than those in the control group at the time points of days 2,7 and 14(P<0.05).On days 2,7 and 14,the viscosity of sputum in the intervention group was better than that in the control group,and the incidence of pulmonary infection in the trial group was significantly lower than that in the control group(P<0.05).Conclusions HVHF and AIRVOTM2 both exhibit no obvious difference in gas humidification via high-flow humidification oxygen therapy in the patients with tracheotomy after withdrawal of ventilator.However,HVHF is superior to AIRVOTM2 in terms of improving airway humidification and oxygenation as well as reducing lung infection.Therefore,it is suggested that an HVHF is preferable for high-flow humidified oxygen therapy in treating the patients with tracheotomy after the withdrawal of ventilator.

Objective:To investigate the changes of white matter fiber bundles in patients with bipolar disorder depressive epoch.Methods:Forty-two patients with unmedicated bipolar disorder (BD) depression and 59 age-, sex- and handedness-matched healthy controls who underwent DTI were recruited in the study. According to the Johns Hopkins University human white matter fiber bundle map, the white matter tissue of the brain was segmented into 20 acknowledged large fiber bundles. The PANDA software was used to calculate the four average diffusion properties of each white matter fiber bundle for each subject. Nonparametric substitution test was used to detect the difference of diffusion index between the two groups on these 20 white matter fiber bundles. Pearson correlation analysis was performed between FA values and RD values extracted from significantly different white matter fiber bundles and clinical indices.Results:In comparison to the normal controls, BD patients had a significant decreased fractional anisotropy (FA) values in the left uncinate fasciculus (0.40±0.01 vs. 0.41±0.01, P=0.001) and the forceps minor (0.36±0.02 vs. 0.38±0.02, P<0.001). Additionally, the radial diffusivity values increased in the left uncinate fasciculus (6.57×10 -4±2.41×10 -5vs. 6.40×10 -4±2.42×10 -5, P=0.001 7). Pearson correlation analysis showed that there were no significant correlations among the clinical indices the FA values and AD values in the left uncinate fasciculus and forceps minor. Conclusions:The patients with bipolar disorder in depression possibly have abnormal left uncinate fasciculus and the forceps minor.
