ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective: To analyze the impact of premature death due to four major chronic diseases on life expectancy in Yangpu District, Shanghai Municipality from 2010 to 2021, so as to provide the evidence for formulating chronic disease prevention and control strategies. Methods : Mortality data of registered residents in Yangpu District from 2010 to 2021 were collected through the Death Information Registration and Management System of the Shanghai Municipal Disease Control and Prevention Information Management Platform. The premature death probability of malignant tumors, diabetes, cardiovascular and cerebrovascular diseases, and chronic respiratory diseases, and life expectancy of residents were calculated using the abridged life table method. Trends in premature death probability for four types of chronic diseases were analyzed using the average annual percent change (AAPC). The impact of premature death probability due to four chronic diseases on life expectancy was assessed by Arriaga's decomposition method. Results : The premature death probability due to four major chronic diseases in Yangpu District decreased from 9.88% in 2010 to 9.22% in 2021, showing an overall declining trend (AAPC=-0.540%, P<0.05). Among females, the premature death probability declined from 6.71% to 4.90% (AAPC=-2.715%, P<0.05), whereas no statistically significant trend was observed in males (P>0.05). Life expectancy increased from 82.52 years in 2010 to 84.50 years in 2021, with an overall upward trend (AAPC=0.244%, P<0.05). Life expectancy rose by 1.71 years for males and 2.34 years for females (AAPC=0.197% and 0.303%,both P<0.05). Declines in premature death probability from malignant tumors (AAPC=-0.967%, P< 0.05) and chronic respiratory diseases (AAPC=-3.071%, P<0.05) contributed to gains in life expectancy of 0.30 years and 0.03 years, with contribution rates of 12.18% and 1.29%, respectively. Changes in premature death probability due to diabetes as well as cardiovascular and cerebrovascular diseases were not statistically significant (both P>0.05), resulting in reductions in life expectancy of 0.05 years and 0.10 years, with contribution rates of -2.40% and -5.05%, respectively. Notably, an increase in premature death probability due to cardiovascular and cerebrovascular diseases among males (AAPC=1.673%) contributed to a decrease of 0.22 years in male life expectancy, whereas a decrease among females (AAPC=-3.824%) contributed to an increase of 0.03 years in female life expectancy, with contribution rates of -13.03% and 1.14%, respectively. Conclusions From 2010 to 2021, Yangpu District experienced an overall decline in premature death probability due to four major chronic diseases and an increase in life expectancy. Greater attention should be paid to the negative impacts of premature death probability from diabetes as well as cardiovascular and cerebrovascular diseases among males on life expectancy.

Depression is a prevalent mental and emotional disor-der that often results in significant emotional disturbances,cog-nitive dysfunction,and memory impairments.It is characterized by a high incidence rate,a substantial disability burden,and limited therapeutic efficacy.Currently,the long-term use of medications for the treatment of depression can result in a range of adverse reactions,highlighting the urgent need to explore no-vel approaches that can effectively alleviate depressive symptoms while minimizing side effects.Curcumin,a natural polyphenolic compound derived from the rhizome of turmeric,demonstrates considerable potential in the prevention and treatment of depres-sion,owing to its diverse array of biological activities.In recent years,numerous studies have investigated the use of curcumin for the treatment of depression.This article aims to provide a comprehensive review of the mechanisms of action underlying curcumin's efficacy in treating depression.Specifically,it focu-ses on its ability to improve neurotransmitter imbalances,restore neural plasticity,alleviate neural damage,mitigate dysfunction of the hypothalamic-pituitary-adrenal(HPA)axis,regulate in-flammatory factors and neuroinflammatory signaling pathways,and inhibit oxidative stress.This review is intended to offer in-sights and methodological references for basic research on curcu-min,as well as for the development of novel therapeutic agents for the treatment of depression.

Objective:To investigate the effect of platelet irradiation on the efficacy and safety of platelet transfusion in children with hematological disorders.Methods:The platelet transfusion of 56 pediatric patients in the Hematology Department of Wuhan Children's Hospital from January to December 2023 were retrospective analyzed.According to whether the platelets transfused by the patient have been irradiated,they are divided into irradiation group and non irradiation group.The effect of platelet irradiation on efficacy rate of transfusion and incidence of transfusion adverse reactions was analyzed.Results:Fifty-six patients with hematological disorders received 608 platelet transfusions,with 83 transfusions ineffective and an inefficiency rate of 13.65％.Twenty-nine times of adverse transfusion reactions occurred,with a transfusion reaction incidence rate of 4.77％.The 24-hour CCI value of the irradiation group was lower than that of the non irradiation group(Z=4.120,P＜0.01),and the effective rate of transfusion in the irradiation group was lower than that in the non irradiation group(x2=8.595,P＜0.01).The incidence of adverse reactions during transfusion in the irradiation group was lower than that in the non irradiation group(x2=4.153,P＜0.05).In children with acute leukemia,there were statistical differences in 24 h CCI,the effective rate of transfusion,and adverse transfusion reactions between the irradiation and non-irradiation groups.Conclusion:Platelet irradiation can reduce the effective rate of platelet transfusion in children with hematological disorders,but can reduce the incidence of adverse transfusion reactions.To ensure the safety of blood use for pediatric patients,it is recommended to transfuse irradiated platelets to individuals who are susceptible to transfusion associated graft-versus-host disease(TA-GVHD),especially children with acute leukemia.

Recommendations cover four aspects of management requirements, assessment, prevention, and management of central venous access device associated skin impairment, providing a practical basis for clinical healthcare professionals to make scientific decisions on central venous access device associated skin impairment.

BACKGROUND:Neurodegenerative diseases are closely related to the imbalance of mitochondrial autophagy regulation.Previous studies by the research group have shown that lycium barbarum polysaccharide has neuroprotective effects,but whether it can improve the damage of SH-SY5Y cells induced byβ-amyloid protein 1-42 by regulating mitochondrial autophagy is still unclear.OBJECTIVE:To explore the protective effect and mechanism of Lycium barbarum polysaccharide on SH-SY5Y cells induced by β-amyloid protein 1-42.METHODS:An Alzheimer's disease cell model was established by inducing SH-SY5Y cells with β-amyloid protein 1-42,and then intervening with Lycium barbarum polysaccharide.SH-SY5Y cells were divided into three groups:control group,β-amyloid protein 1-42 group(20 μmol/L β-amyloid protein 1-42 for 24 hours),and Lycium barbarum polysaccharide group(1 g/L Lycium barbarum polysaccharide was added 1 hour in advance to form a protective effect,and then 20 μmol/L β-amyloid protein 1-42 was added to intervene with Lycium barbarum polysaccharide for 24 hours).CCK8 assay was used to detect cell viability.Mitochondrial membrane potential was detected by JC-1.TUNEL staining was used to detect cell apoptosis.Immunofluorescence and western blot assay were used to detect the expression of synaptic,apoptosis,and mitophagy-related indicators.RESULTS AND CONCLUSION:(1)Compared with the control group,the cell viability of the β-amyloid protein 1-42 group decreased(P＜0.05);cell apoptosis rate increased(P＜0.05);mitochondrial membrane potential decreased(P＜0.05);the expressions of pro-apoptotic proteins Bax and Caspase3 increased(P＜0.05);the expression of anti-apoptotic protein Bcl-2 decreased(P＜0.05);the expression levels of synaptic-related proteins Syn and PSD-95 decreased(P＜0.05);the expression levels of mitochondrial autophagy-related proteins Pink1,LC3A/B,Parkin,and Beclin-1 decreased(P＜0.05);and the expression of P62 increased(P＜0.05).(2)Compared with the β-amyloid protein 1-42 group,the cell viability in the Lycium barbarum polysaccharide group was increased(P＜0.05);the apoptosis rate was decreased(P＜0.05);the mitochondrial membrane potential was increased(P＜0.05);the expression levels of Bax and Caspase3 were decreased(P＜0.05);the expression of Bcl-2 was increased(P＜0.05);the expressions of Syn and PSD-95 were increased(P＜0.05);the expression levels of Pink1,LC3A/B,Parkin,and Beclin-1 were increased(P＜0.05),and the expression of P62 was decreased(P＜0.05).These findings indicate that Lycium barbarum polysaccharide may inhibit β-amyloid protein 1-42-induced damage to SH-SY5Y cells by regulating mitophagy,reduce cell apoptosis,and increase neuronal synaptic plasticity.

Aim To explore the relevant mechanisms of isoliquiritigenin(ISL)in inhibiting the proliferation and migration of vascular smooth muscle cells(VSMCs)by regulating the GRB2/ERK signaling pathway.Methods Human primary vascular smooth muscle cells(hVSMCs)were cultured,and stimulated with different concentrations of ISL and fixed concen-trations of growth factors PDGF-BB and EGF,respec-tively.Subsequently,the effect of overexpressing GRB2 on the efficacy of ISL was observed.CCK-8 assay was used to detect cell proliferation;BrdU assay was used to detect DNA synthesis;Western blot was used to de-tect the expression levels of OPN,ICAM-1,VCAM-1,GRB2,ERK1/2,and p-ERK1/2;wound healing assay was used to detect cell migration;transwell assay was used to detect cell invasion.Results Compared with the blank control group and the ISL 20 mg·L-1 group,the PDGF-BB group and the EGF group showed increased cell viability and DNA synthesis,decreased cell migration distance,and increased number of inva-sive cells.Additionally,the expression levels of GRB2 and p-ERK1/2 increased.Compared with the PDGF-BB 40 μg·L-1group or the EGF 10 mg·L-1 group,the ISL drug intervention group showed decreased cell viability and DNA synthesis,increased migration dis-tance of cells,decreased number of invasive cells,and decreased expression levels of GRB2 and p-ERK1/2.Compared with the ISL 20 mg·L-1+PDGF-BB and ISL 20 mg·L-1+EGF groups,the groups with ISL+PDGF-BB+pcDNA-GRB2 group and ISL+EGF+pcDNA-GRB2 group showed increased expression lev-els of GRB2,p-ERK1/2,OPN,ICAM-1,and VCAM-1,increased cell viability and DNA synthesis,decreased migration distance,and increased number of invasive cells.Compared with the ISL+PDGF-BB+pcDNA-GRB2 group and the ISL+EGF+pcDNA-GRB2 group,the pcDNA-GRB2+PDGF-BB group or the pcDNA-GRB2+EGF group showed increased expres-sion levels of GRB2,p-ERK1/2,OPN,ICAM-1,and VCAM-1,increased cell viability and DNA synthesis,decreased migration distance,and increased number of invasive cells.Conclusions Isoliquiritigenin inhibits the proliferation and migration of vascular smooth mus-cle cells by regulating the GRB2/ERK signaling path-way.
