Objective:To analyze inpatients preferences for an unaccompanied ward and its influencing factors, for references for the implementation of unaccompanied ward management.Methods:Based on a convergent mixed research design, a convenience sampling method was used to select inpatients who visited a tertiary hospital from June to August 2024 as the survey subjects. A questionnaire survey was conducted on their willingness to choose the unaccompanied ward (provided by medical nursing staff). Meanwhile, using purposive sampling method, 10 inpatients and 11 accompanying family members were selected for semi-structured interviews about unaccompanied ward prference, and the interview topics were summarized and extracted. The results of quantitative and qualitative were compared and integrated.Results:The quantitative research results showed that among the 805 inpatients included, 125 patients (13.03%) chose medical caregivers, 382 patients (39.83%) chose their spouses, and 272 patients (28.36%) chose their children; 411 patients (24.54%) did not choose medical caregivers due to financial burden; 509 patients (63.23%) believed that the cost of an unaccompanied ward should be less than 120 yuan/day. The qualitative research results showed that the interview data formed three themes, including the driving factors of caregiving form selection intention, the emotional tendency of caregiving form selection intention, and the assessment of the benefits and drawbacks of caregiving form selection intention. The mixed research results showed that the majority of inpatients choose their spouse or children accompany them, and their willingness to choose medical caregivers is mainly influenced by service costs and family labor. However, its did not affect patients who are young or have difficulty caring for them; Influenced by traditional Chinese culture, patients tended to choose relatives to accompany them; The main reasons why patients did not choose unaccompanied wards were the economic burden and the mismatch between medical nursing staff services and their expectations.Conclusions:Inpatients tended to choose family members to accompany them. Their willingness to choose unaccompanied ward was influenced by economic burden, family labor, patient age, caregiving difficulty, and filial piety culture.

Objective By observing and measuring the relevant data of the buccal branch of the facial nerve,the parotid duct and the facial artery,the positional relationship among the three was analyzed to avoid accidental injury to the buccal branch of the facial nerve and the parotid duct when ligaturing the facial artery during the operation.Methods Forty adult head and neck specimens were dissected to observe the relationship between the buccal branch of the facial nerve and the parotid duct,the course and positional relationship of the facial artery,and the relationship between the buccal branch of the facial nerve and the peripheral vascular network.The relevant diameters were measured with a vernier caliper.Results The buccal branch of the facial nerve was divided into the superior buccal branch and the inferior buccal branch,and there was no direct anastomosis or connecting fiber between the buccal branch of the facial nerve and the parotid duct.The superior buccal branch was relatively thick,and it has a relatively constant position,which was parallel to the parotid duct.The position of the inferior buccal branch was not constant and it ran on or slightly above the plane of angulus oris.The superior buccal branch was located(10.76±5.54)mm from the parotid duct,while the inferior buccal branch was positioned(6.84±4.06)mm away from the parotid duct.The course of the main trunk of the facial artery was relatively fixed.Moreover,if the branch of the facial artery was missing,other branches of the facial artery would extend to replace the missing branch artery.The main trunk of the facial artery had a diameter of(2.34±0.83)mm,and its branches formed anastomoses with the buccal branch of the maxillary artery,creating a vascular network in the parotid and buccal regions.There was a vascular network around the buccal branch of the facial nerve,which was mostly small branches of the facial artery and the superficial temporal artery.Conclusion The buccal branch of the facial nerve exhibits a consistent anatomic relationship with the parotid duct and the facial artery.During the ligation of the facial artery,the parotid duct can serve as a landmark to accurately locate the buccal branch of the facial nerve,thereby significantly reducing the risk of inadvertent injury to the buccal branch of the facial nerve and the parotid duct.

Aim To investigate the effect of icariin(ICA)on chronic ulcerative colitis(UC)in mice.Methods Male SPF-grade C57BL/6J mice were ran-domly divided into the control group,model group,low-dose ICA group,and high-dose ICA group.Except for the control group,the rest of the mice were established as chronic UC models.Expressions of tight junction proteins,inflammatory factors,fibrosis markers,macro-phage markers,and MAPK signaling pathways in the colonic epithelium of each group were determined by Western blot,qPCR,immunohistochemistry;the degree of intestinal damage and fibrosis was detected by HE and Masson staining;the co-localization of different macrophage markers with related factors was examined by immunofluorescence.Results Treatment of ICA significantly improved the general condition of chronic UC mice,decreased the infiltration of M1-type macro-phages and the secretion of pro-inflammatory factors,inhibited the MAPK signaling pathway,reduced the co-localization expression of M1-type macrophages with the MAPK signaling pathway,and downregulated the infiltration of M2-type macrophages and the secretion of pro-fibrotic factors in the colon.Conclusion ICA mitigates the inflammatory damage and fibrosis of colon in chronic UC mice.

In the context of high-quality development in medical institutions, the supply-processing-distribution(SPD) management mode has gradually been widely applied. The authors described in detail the procurement, supply, inventory, distribution, and settlement management of medical consumables and in vitro diagnostic reagents in a certain hospital under the SPD mode. It was found that SPD was conducive to strengthening the supervision of medical consumables and in vitro diagnostic reagents in the hospital, ensuring quality and safety of use, reducing hospital operating costs, and improving hospital′s competitiveness. However, attention should be paid to preventing data security risks, strengthening operational management, and improving the cost-benefit analysis of in vitro diagnostic reagents.

Objective:To evaluate the effect of low-dose recombinant interleukin-2(rIL-2)therapy on immunocyte subsets and its side effects in children with solid tumor.Methods:A total of 22 children(11 males and 11 females)with solid tumor in our department from December 2012 to November 2017 were selected,with a median age of 9(3-16)years old when starting IL-2 therapy.ALL surgeries and chemotherapy of children had been completed before low-dose rIL-2 therapy,and 17 cases achieved complete remission(CR)and 5 cases achieved partial remission(PR).A low-dose rIL-2 therapy was given 1 month after chemotherapy for 1 year:4 × 105 IU/(m2·d),s.c.for every other day,3 times per week.The immunocyte subsets were detected every 3 months until the end of treatment,meanwhile,disease condition and therapy-related side effects were followed up.Results:After low-dose rIL-2 therapy in 22 children,the absolute values of CD3+T cells,CD3-CD56+natural killer cells,CD3+CD4+helper T cells(Th)and CD3+CD8+cytotoxic T cells were up-regulated remarkably,as well as Th/suppressor T cells(all P＜0.05).While,there were no significant differences in absolute value and proportion of CD4+CD25+CD127-Treg cells during therapy.Among the 17 children who achieved CR before rIL-2 therapy,14 cases continued to maintain CR after therapy,while 3 cases relapsed,and with 2 died after treatment abandonment.The 5 children who achieved PR before low-dose rIL-2 therapy were evaluated CR by PET/CT scan after treatment.In the early stage of low-dose rIL-2 therapy,1 child developed skin rashes at the injection sites,and 2 children ran a slight to mild transient fever.Their symptoms disappeared without any organ damage after symptomatic treatment.Conclusion:Low-dose rIL-2 therapy has good drug tolerance,and changes the distribution of anti-tumor immune-cell subgroup in peripheral blood of children with solid tumor remarkably without up-regulation of absolute value and ratio of Treg cells.

Nonalcoholic steatohepatitis (NASH) is a spectrum of chronic liver disease characterized by hepatic lipid metabolism disorder. Recent reports emphasized the contribution of triglyceride and diglyceride accumulation to NASH, while the other lipids associated with the NASH pathogenesis remained unexplored. The specific purpose of our study was to explore a novel pathogenesis and treatment strategy of NASH via profiling the metabolic characteristics of lipids. Herein, multi-omics techniques based on LC-Q-TOF/MS, LC-MS/MS and MS imaging were developed and used to screen the action targets related to NASH progress and treatment. A methionine and choline deficient (MCD) diet-induced mouse model of NASH was then constructed, and Schisandra lignans extract (SLE) was applied to alleviate hepatic damage by regulating the lipid metabolism-related enzymes CES2A and CYP4A14. Hepatic lipidomics indicated that MCD-diet led to aberrant accumulation of phosphatidylethanolamines (PEs), and SLE could significantly reduce the accumulation of intrahepatic PEs. Notably, exogenous PE (18:0/18:1) was proved to significantly aggravate the mitochondrial damage and hepatocyte apoptosis. Supplementing PE (18:0/18:1) also deteriorated the NASH progress by up regulating intrahepatic proinflammatory and fibrotic factors, while PE synthase inhibitor exerted a prominent hepatoprotective role. The current work provides new insights into the relationship between PE metabolism and the pathogenesis of NASH.

ObjectiveTo investigate the pharmacological effect and metabolic mechanism of Linderae Radix on the intrauterine adhesion （IUA） rat model. MethodAn IUA rat model was induced by mechanical injury and infection. Molecular biology and pharmacology techniques were employed to evaluate the inhibitory effect of Linderae Radix extract （LAE） on fibrosis in IUA. Serum metabolomics analysis based on gas chromatography-mass spectrometry （GC-MS） was conducted to explore the metabolic regulation mechanism of LAE. ResultAnimal experiments showed that LAE significantly improved the morphology and structural damage of uterine tissue cells in the IUA rat model， promoted endometrial proliferation， vascular regeneration， and morphological recovery， inhibited the mRNA expression of transforming growth factor-β₁ （TGF-β₁）， Smad2， and Smad3， and increased the expression of Smad7 mRNA to suppress fibrosis. Additionally， LAE significantly suppressed the levels of estrogen （E₂）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and tumor necrosis factor-α （TNF-α） expression （P<0.01）， thereby improving the uterine microenvironment. Metabolomics analysis revealed significant metabolic abnormalities in the serum of IUA rats compared with the results in the normal group， and nine differential metabolites were identified. LAE effectively ameliorated these metabolic abnormalities， primarily by influencing six differential metabolites， including five shared metabolites among the nine identified markers： L-aspartic acid， L-pyroglutamic acid， L-serine， glucose， and L-norvaline. Pathway enrichment analysis indicated that the aminoacyl-tRNA biosynthesis pathway was the main affecting mechanism. ConclusionIn combination with the pharmacological research results， LAE effectively improved uterine damage and inhibited fibrosis in the IUA rat model. Its mechanism may involve the inhibition of the aminoacyl-tRNA biosynthesis pathway and the improvement of the microenvironment.
