OBJECTIVE To evaluate the cost-utility of ciclesonide （CIC） versus budesonide （BUD） for the maintenance treatment of mild to moderate bronchial asthma. METHODS From the perspective of Chinese health service system， a Markov model was established based on the data from a clinical trial in China and some literature. The cycle length was 1 week， the time horizon was 60 years. A discount rate of 5% per year was applied. Cost-utility analysis was performed on therapeutic scheme of CIC and BUD using three times of China’s per capita gross domestic product （GDP） in 2023 as the threshold of willing-to-pay （WTP）. One-way sensitivity analysis， probabilistic sensitivity analysis and scenario analysis were applied to test the uncertainty of basic analysis. RESULTS Compared with BUD scheme， the incremental cost of the CIC scheme was 9 401.67 yuan， and the incremental quality-adjusted life years（QALYs） were 0.001 3； incremental cost-effectiveness ratio （ICER） was 6 928 868.26 yuan/QALY， far beyond the threshold of WTP 268 074 yuan/QALY. One-way sensitivity analysis showed that the usage， dosage and unit price of CIC and BUD were parameters that had a significant impact on ICER； probabilistic sensitivity analysis showed that the basic analysis results were relatively robust； scenario analysis showed that， when the price of CIC reduced to 159.95 yuan/branch， the probability of CIC scheme having economics was similar to that of BUD scheme. CONCLUSIONS At the current price， CIC is not economical compared with BUD for the maintenance treatment of mild to moderate asthma， using three times of China’s GDP in 2023 as the threshold of WTP.

OBJECTIVE To provide reference for relevant departments to improve the drug provision in children’s hospitals and further implement clinical management practices for rational drug use in pediatric patients. METHODS According to the drug purchasing statistics of four sample class A tertiary children’s hospitals in Jiangsu province from 2012 to 2023， this study systematically reviewed and analyzed the drug provision and utilization in children’s hospitals， including the number of pharmaceuticals procured and used in hospitals， the concentration of drug usage among different hospitals， the situation of drugs recommended by the National Essential Medicine List and children’s clinical diagnosis and treatment guidelines， and the standardization of clinical medication. RESULTS In 2023， the number of commonly used drugs in 4 tertiary children’s hospitals was 922 varieties and 1 401 specifications， which was significantly lower than the total number of currently marketed children’s drugs. However， the concentration of drug usage among different hospitals was not high， with the proportion of drugs supplied and used in only one hospital accounting for approximately 40% and 50% respectively in terms of drug variety and specification. At present， among the drugs procured and used in sample children’s hospitals， the proportion of national essential medicines basically maintained between 30% and 40%， while drugs which could be safely and effectively used for children was about 60%. In addition， around 40% of the drug varieties recommended in pediatric clinical practice guidelines had also been applied in clinical treatment. Nevertheless， about 30% to 40% of prescription behavior was dependent on doctors’ personal experience and the phenomena of drugs prohibited and unsuitable use for children still existed. CONCLUSIONS Although the number of clinical medications for children in China is limited， there are significant differences in the overall medication choices made by hospitals. The scientific， rational and standardized use of clinical medications also needs to be further strengthened.

Background The decline of physical activity in the elderly due to aging may increase the risk of sarcopenia. Currently, there is a lack of evidence from large natural populations on the relationship between PA and sarcopenia. Objective To explore the relationship between PA and sarcopenia in the elderly aged 60 years and above in 10 provinces (autonomous regions) of China. Methods Data were retrieved from the 2022—2023 round of the China Development and Nutrition Health Impact Cohort. Personal basic information and PA data were collected by questionnaire survey. Skeletal muscle mass was measured by bio-electrical impedance analysis, muscle strength was measured using a grip dynamometer, and physical performance was reflected by 6-meter walk speed. The Asian Working Group for Sarcopenia (AWGS) 2019 criteria were used to diagnose sarcopenia. Light physical activity (LPA) duration, moderate-to-vigorous physical activity (MVPA) duration, and total physical activity volume were calculated. A total of 3326 residents aged ≥60 years with complete data were selected as the survey participants. Multiple logistic regression models and restricted cubic splines (RCS) were used to assess the association between PA duration/volume and sarcopenia. Results In 10 provinces (autonomous regions) of China, the prevalence of sarcopenia in the elderly aged 60 years and above was 5.5% (95%CI: 4.7%, 6.2%). The logistic regression analysis showed that compared with the elderly reporting 0-7.0 h·week⁻¹ in LPA duration, the risk of sarcopenia in the elderly with LPA duration of >14.0-21.0 h·week⁻¹ was reduced by 51% (OR=0.49, 95%CI: 0.26, 0.96). Compared with the elderly with total physical activity ≥15.0 metabolic equivalent of task (MET)-h·week⁻¹, those with <7.5 MET-h·week⁻¹ had a 2.24-fold increased risk of sarcopenia (OR=2.24, 95%CI: 1.17, 4.29). The RCS results found that LPA duration and total physical activity volume each showed a nonlinear dose-response relationship with the risk of sarcopenia (P_overall<0.05, P_non-linear<0.05). Compared with the elderly with an LPA duration of 0 h· week⁻¹, the risk of sarcopenia in the elderly with an LPA duration of 12.6 h· week⁻¹ was the lowest (OR=0.42, 95%CI: 0.21, 0.83). Compared with the elderly with a total physical activity volume of 15.0 MET-h· week⁻¹, the elderly with a total physical activity volume of 46.0 MET-h· week⁻¹ had the lowest risk of sarcopenia (OR=0.57, 95%CI: 0.38, 0.84). There was no statistically significant association between weekly MVPA duration and the risk of sarcopenia (P>0.05). Conclusion Increasing weekly LPA duration and total physical activity volume would help to reduce the risk of sarcopenia.

Objective To study the protective effect of polydatin on lipopolysaccharide-induced injury of human umbilical vein vascular endothelial cells(HUVECs)through the protein Janus kinase 2(JAK2)/signal transducers and activators of transcription 3(STAT3)signaling pathway.Methods HUVECs were cultured in vitro,and 500 ng/ml LPS induced their injury and set as a model group;based on the model group,endothelial cells were inter-vened with different concentrations(10,20,and 40 μmol/L)of polydatin for 24 h,and set as polydatin low concentration group,polydatin medium concentration group,and polydatin high concentration group,respectively;a control group was set as another group.CCK-8,monocyte-endothelial cell adhesion,scratch and Transwell assays were used to detect cell viability,adhesion,migration and invasive ability;ELISA was used to detect interleukin-6(IL-6)and tumor necrosis factor-alpha(TNF-α)levels in the cell supernatant;Western blot was used to detect the expression of proteins related to the JAK2/STAT3 signaling pathway levels of JAK2/STAT3 signaling pathway relat-ed proteins.Results Compared with the control group,the model group showed decreased cell survival(P＜0.01),increased cell adhesion,migration and invasion(P＜0.001,P＜0.05,P＜0.01),increased levels of IL-6 and TNF-α in the cell supernatant(P＜0.001),and increased levels of phosphorylation of JAK2 and STAT3 pro-teins in the cells(P＜0.05).Compared with the model group,LPS damage to cells was attenuated after polydatin intervention,cell survival was increased in polydatin low-,medium-and high-concentration groups(P＜0.05),cell adhesion,migration,and invasion decreased(P＜0.05,P＜0.05,P＜0.001),IL-6 and TNF-α levels in cell supernatants decreased(P＜0.05),and the levels of cellular JAK2 and STAT3 protein phosphorylation lev-els decreased(P＜0.05).Conclusion Polydatin seems to reduce the inflammatory injury of human umbilical vein endothelial cells induced by LPS,reducing the secretion of inflammatory factors,and inhibiting the ability of cell ad-hesion,migration and invasion,which may be related to the down-regulation of JAK2/STAT3 signal pathway by polydatin.

Objective To investigate the effect of glycine N-methyl transferase (GNMT)on intrauterine adhesion (IUA)fibrosis and its related mechanism.Methods In vivo experiment:A total of 36 healthy female SD rats (SPF grade,6～8 weeks old and weighing from 180～220 g)were subjected in this study.IUA model of SD rats and IUA model of GNMT overexpressed rats were established.RT-qPCR and immunofluorescence assay were applied to detect GNMT expression level in normal uterus and model group.RT-qPCR and Western blotting were used to detect the mRNA and protein levels of fibrosis-related molecules and the activation of TGF-β1/Smad3 signaling pathway in each group.The number of endometrial glands in each group was observed by HE staining.Masson staining was used to analyze the severity of endometrial fibrosis in each group.In vitro experiment:transformed human endometrial stromal cells (THESCs)fibrotic phenotype model was constructed using TGF-β1,and THESCs stably transfected with GNMT overexpression lentvirus were treated with TGF-β1.RT-qPCR and Western blotting were used to detect the mRNA and protein expression of fibrosis-related molecules.The expression of TGF-β1/Smad3 signaling pathway was detected by Western blotting.TGF-β1/Smad3 signaling pathway was activated by TGF-β1/Smad signaling pathway activator (SRI-011381),and the expression of TGF-β1/Smad3 signaling pathway and key molecular proteins of fibrosis phenotype was measured with Western blotting.Results In vivo experiment,the mRNA and protein expression levels of GNMT were significantly decreased in the IUA rats than the control rats (P<0.05).Overexpression of GNMT decreased the mRNA and protein levels of fibrosis related molecules,Collagen Ⅰ,Collagen Ⅲ and FN in the IUA rats (P<0.05),and decreased the phosphorylation levels of TGF-β1 and its downstream Smad3 protein (P<0.05).HE and Masson staining showed that overexpression of GNMT could increase the number of endometrial glands and reduce the severity of fibrosis in the IUA rats (P<0.05).In vitro experiments:overexpression of GNMT decreased the mRNA and protein levels of Collagen Ⅰ,Collagen Ⅲ and FN associated with fibrotic phenotype of THESCs (P<0.05),and reduced the phosphorylation level of Smad3 protein,downstream of TGF-β1 (P<0.05).After activation of TGF-β1/Smad3 signaling pathway,the protein levels of TGF-β1/Smad3 signaling pathway and downstream fibrosis phenotype molecules,Collagen Ⅲ and FN,were significantly decreased in the LV-GNMT+SRI-011381 group.Conclusion Overexpression of GNMT can inhibit endometrial fibrosis by regulating TGF-β1/Smad3 signaling pathway,thus achieving therapeutic effect on IUA.

β thalassemia is a hereditary hemolytic disease caused by the defect of β globin gene. Transfusion-dependent β thalassemia patients need long-term blood transfusion to survive, and a series of systemic and ocular complications will occur in the disease itself and long-term blood transfusion. Retinal blood vessel density decreases, retinal thickness thinned and elastic pseudoxanthoxanoma syndrome are found in fundus due to long-term anemia and side effects of iron chelating agent. At present, there are few reports about eye changes in thalassemia patients, and the cognition is relatively scarce. Therefore, it is necessary to be vigilant for physicians, deeply explore the cause and symptomatic treatment, combined with individual disease characteristics, to provide a more scientific and accurate plan for clinical treatment.

Objective To explore application of feedforward control nursing intervention in anesthesia recovery management of patients undergoing robot-assisted thoracoscopic radical resection for lung cancer.Methods Sixty-four patients underwent robot-assisted thoracoscopic radical resection for lung cancer at People's Hospital of Liaocheng City in Shandong Province from December 2021 to May 2022 were selected as research objects.They were randomly divided into control group and experimental group,with 32 cases in each group.Control group received routine nursing measures,while experimental group received nursing intervention under guidance of feedforward control on basis of control group.Pass rate of nurses relevant theoretical knowledge,incidence of perioperative complications,nursing satisfaction,nursing quality score,recovery room stay time,self-rating anxiety scale(SAS)and self-rating depression scale(SDS)scores before operation and when leaving recovery room were compared between two groups.Results Pass rate of nurses relevant theoretical knowledge in experimental group was significantly higher than that in control group(P<0.05).Total incidence rate of pressure injury,incidence rate of fluid circuit problems,agitation and hypothermia in experimental group were significantly lower than those in control group(P<0.05).Nursing effect,nursing professionalism,nursing operation and nursing attitude scores of experimental group were significantly higher than those of control group,and recovery room stay time of experimental group was significantly shorter than that of control group(P<0.05).When leaving recovery room,SAS and SDS scores of experimental group were significantly lower than those of preoperative in this group and control group(P<0.05).Conclusion Application of feedforward control nursing intervention in robot-assisted thoracoscopic lung cancer patient anesthesia recovery management can effectively reduce incidence of perioperative complications,shorten recovery time,improve nursing satisfaction and nursing quality scores,and improve patients'early postoperative anxiety and depression status,which is worthy of clinical application and promotion.

Objective:To investigate the expression of miRNA-144 in the peripheral blood of patients with type 2 diabetes foot ulcer (DFU) and its correlation with the pathogenesis of the disease.Methods:A total of 106 patients with DFU admitted to the General Hospital of the Western Theater Command of the Chinese People′s Liberation Army from March 2020 to June 2022 were retrospectively selected as the observation group, and 106 patients with type 2 diabetes mellitus (T2DM) who did not have DFU admitted to our hospital during the same period were selected as the control group. According to the median expression level of miRNA-144 in peripheral blood of DFU patients as the segmentation point, 106 patients in the observation group were divided into low expression group and high expression group. We compared the clinical data of the observation group and the control group, and analyzed the relationship between different levels of miRNA-144 expression and clinical characteristics of DFU patients; A multivariate analysis was conducted on the factors related to the occurrence and development of the disease course in DFU patients, and a column chart model was constructed for model validation.Results:The course of diabetes, fasting blood glucose (FPG), erythrocyte sedimentation rate (ESR), glycosylated hemoglobin (HbA 1c), white blood cell count (WBC), C-reactive protein (CRP), corticotropin releasing hormone (CRH), interleukin-6 (IL-6), adrenaline (E), norepinephrine (NE), cortisol (Cor) and miRNA-144 expression levels in the observation group were significantly higher than those in the control group, while transcutaneous partial pressure of oxygen (TcPO 2), ankle brachial index (ABI), triglyceride (TG) and hemoglobin (Hb) were significantly lower than those in the control group, the difference was statistically significant (all P<0.05). There were statistically significant differences in foot ulcer healing rate, Wagner grading, and ulcer course between the high expression group of miRNA-144 and the low expression group of DFU patients after 8 weeks (all P<0.05). Multivariate regression analysis showed that the duration of diabetes>5 years, HbA 1c>8.5%, TcPO 2<60 mmHg, CRP>10 mg/L, Cor>190 μg/L, and miRNA-144 expression level>35 were independent risk factors for the occurrence of DFU in T2DM patients. The total score of 315 points after constructing the nomogram prediction model for the above factors, and the corresponding probability of occurrence and development of DFU was 72.56%. Conclusions:The expression level of miRNA-144 in the peripheral blood of DFU patients is significantly related to the occurrence and development of the disease course, and the course of diabetes and the changes of HbA 1c, TcPO 2, CRP, Cor levels are independent risk factors for the occurrence and development of DFU, which should be focused on clinically.

Objective:To evaluate the relationship between the Geriatric Nutritional Risk Index (GNRI) and postoperative pulmonary complications (PPCs) in elderly patients undergoing thoracoscopic lung resection.Methods:Two hundred and ninety-one elderly patients of either sex, aged ≥60 yr, of American Society of Anesthesiologists Physical Status classificationⅠ-Ⅲ, undergoing elective thoracoscopic lung resection at Xuzhou Cancer Hospital from July 2022 to September 2023, were selected. Patients were divided into high GNRI group or low GNRI group based on the optimal cutoff value of GNRI (represented as a continuous variable) determined by the receiver operating characteristic curve to predict PPCs. The occurrence of PPCs was compared between the two groups within the first 7 postoperative days. The relationship between GNRI and PPCs was evaluated by the logistic regression analysis. The nonlinear correlation between GNRI score (expressed as a continuous variable) and PPCs was investigated by the restricted cubic spline. The accuracy of the GNRI, Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score, and combination of the two in predicting the occurrence of PPCs was evaluated by the areas under the ROC curve (95% confidence interval[ CI]). Results:A total of 269 patients were finally included, with 114 in high GNRI group (GNRI≥100.9) and 155 in low GNRI group (GNRI<100.9). Compared with high GNRI group, the incidence of PPCs was significantly increased compared with low GNRI group (42.6% vs 16.7%, P<0.001). The multivariate logistic regression analysis showed that low GNRI was a risk factor for PPCs, while elevated GNRI score was a protective factor for PPCS in elderly patients undergoing thoracoscopic lung resection ( P<0.05). The restricted cubic spline showed a linear correlation between GNRI score and PPCs ( P=0.947). The areas under the receiver operating characteristic curves of the GNRI, ARISCAT score, and combination of the two in predicting PPCs were 0.646 (95% CI 0.589-0.704), 0.619 (95% CI 0.564-0.674) and 0.708 (95% CI 0.647-0.769), respectively. Conclusions:Low GNRI is an independent risk factor for PPCs in elderly patients undergoing thoracoscopic lung resection, while elevated GNRI score is a protective factor. The combination of GNRI and ARISCAT score can predict the occurrence of PPCs.
