OBJECTIVE To provide references for ensuring the safety of prescription preparation， dispensing， and use of parenteral nutrition solution， as well as for expanding the scope of pharmaceutical services provided by pharmacists in the Pharmacy Intravenous Admixture Services （PIVAS）. METHODS Under the guidance of PIVAS pharmacists， the rules for reviewing medical orders of parenteral nutrition in the PIVAS system and the information displayed on the infusion labels of finished parenteral nutrition solutions were refined. The process management of dispensing parenteral nutrition solution was strengthened， and detailed quality control and inspection rules were formulated. Additionally， Clinical Safety Monitoring Form for Finished Parenteral Nutrition Infusions was designed to conduct clinical monitoring and inspections for abnormalities in the finished infusions， infusion operations， and complications that may arise during the use of finished parenteral nutrition infusions. The implementation effects of the aforementioned optimization/inspection measures were evaluated by comparing data on the efficiency of medical order review for parenteral nutrition， the rate of irrational medical orders， the compliance rate of vascular access selection and infusion rate standardization， the rate of dispensing error， as well as the abnormalities occurring during clinical use， before and after the optimization/inspection initiatives were put into place. RESULTS The optimized prescription review system achieved automatic review of medical orders for parenteral nutrition， enhancing the efficiency of order review. The average time taken to review one parenteral nutrition medical order was reduced from approximately 1 minute to 10 seconds. The irrational rate of parenteral nutrition orders decreased by 31.87%. The dispensing error rate of parenteral nutrition decreased by 56.55%. The standard rate of vascular access selection and standard rate of infusion speed were increased by 13.29% and 3.54%， respectively. The PIVAS pharmacists identified and intervened in 5 abnormal cases out of 298 cases examined for use of parenteral nutrition solutions. CONCLUSIONS By optimizing the prescription review system， improving labeling information， and strengthening quality control inspections during both preparation and administration processes， PIVAS pharmacists have enhanced the safety of compounded parenteral nutrition solutions. This initiative has expanded the scope and depth of pharmaceutical care provided by dispensing pharmacists.

Objective To assess the nutritional status in elderly patients with chronic renal insufficiency (CRI) and reveal the key factors affecting the nutritional status. Methods A total of 310 elderly patients with CRI who received hospitalization treatment and outpatient follow-up in the hospital from January 2021 to June 2024 were selected as the investigation subjects. The nutritional status of patients was evaluated by mini-nutritional assessment (MNA) questionnaire, and the nutritional status and dietary structure of patients were comprehensively evaluated by anthropometric indicators [height, weight, body mass index (BMI), upper arm circumference, calf circumference], biochemical indicators [serum albumin (ALB), prealbumin (PA), hemoglobin (Hb), transferrin (TF)] and 24-hour dietary review method. According to the investigation results of nutritional status, the patients were divided into good nutrition group (MNA score≥24 points), nutritional risk group (MNA score of 17-23.5 points) and malnutrition group (MNA score<17 points). Univariate analysis was adopted to screen the potential influencing factors of elderly CRI. Multivariate logistic regression model was applied to analyze the influencing factors of malnutrition in elderly CRI patients. Results Among the 325 questionnaires were distributed, but only 310 valid questionnaires were recovered, with an effective recovery rate of 95.38%. Investigation results revealed that among the 310 patients, 29.35% (91 cases) had good nutritional status, and 42.26% (131 cases) had nutritional risk, and 28.39% (88 cases) had malnutrition. Univariate analysis indicated that there were statistical differences in BMI, CRI staging, serum ALB, PA, Hb, TF, protein intake and total calorie intake among the good nutrition group, the nutritional risk group and the malnutrition group (P<0.05). Multivariate logistic regression analysis suggested that low BMI (OR=0.903, 95%CI: 0.867-0.941), high CRI stage (OR=1.091, 95%CI: 1.053-1.130), low serum ALB (OR=0.907, 95%CI: 0.867-0.948), PA (OR=0.918, 95%CI: 0.888-0.949), Hb (OR=0.944, 95%CI: 0.909-0.997), TF (OR=0.912, 95%CI: 0.874-0.952), insufficient protein intake (OR=0.924, 95%CI: 0.882-0.969) and insufficient total calorie intake (OR=0.938, 95%CI: 0.909-0.968) were influencing factors for malnutrition in elderly patients with CRI (all P<0.05). Drawing ROC curve of malnutrition in elderly patients with CRI according to the prediction probability of logistic regression model found that the AUC, sensitivity, specificity, 95%CI and Youden index were 0.976, 93.18%, 92.34%, 0.953-0.990 (P<0.05) and 0.855. Conclusion The incidence rate of malnutrition is high in elderly patients with CRI, and is mainly affected by factors such as low BMI, high CRI stage, low serum ALB, PA, Hb and TF levels and insufficient protein and total calorie intakes. In addition, logistic regression model has high predictive value and can provide a reference for early clinical identification of high-risk population with malnutrition among elderly patients with CRI.

OBJECTIVE: To explore the feasibility of establishing a temporary trauma team led by trauma experts in primary hospitals for disaster medical rescue. METHODS: In the coal mine flooding accident in Xiaoyi City, Shanxi Province on December 15, 2021, according to the local emergency plan and the characteristics of the accident, the trauma experts trained the medical staff from the local primary hospital on advanced trauma life support (ATLS) and damage control surgery (DCS) in the short time interval between the occurrence of the mine disaster and the admission of medical staff to the disaster scene. A temporary trauma team composed of trauma experts, ATLS team, and DCS team was formed to provide early diagnosis and treatment for survivors before and in the hospital. RESULTS: The miners were found on the 36th hour of the disaster. All 22 miners were male, and 2 died underground. Another 20 people were rescued 39－43 hours after the disaster, with a median age of 48 years (34-57 years). All the survivors suffered from hypothermia, dehydration, maceration of feet and other injuries. There were 18 cases of acute inhalation tracheobronchitis, 14 cases of electrolyte acid-base disturbance, 6 cases of trunk contusion, 1 case of psoas major hematoma, and 1 case of lower extremity hematoma. Deep vein thrombosis was in 4 cases. The ATLS team focused on injury assessment, rewarming and rehydration within 50－60 minutes before admission, and completed auxiliary examinations within 2 hours after admission to clarify the diagnosis. The DCS team evaluated 6 patients with mechanical blunt trunk injury and excluded the indication of emergency surgery. The trauma experts conducted the whole process of supervision and quality control of disaster rescue. The positive rate of capillary refill test in the all survivors at the third hour of admission was significantly lower than that immediately after being rescued (75.0% vs. 15.0%, P=0.000 3), and they were discharged 4－7 days after admission. CONCLUSION Under the leadership of trauma experts and relying on the medical staff of primary hospitals, it is feasible to establish and train a temporary trauma team with ATLS and DCS functions to participate in the medical rescue of disasters, which is in line with the current national conditions of China.

Two novel diketopiperazines (1 and 5), along with ten known compounds (2-4, 6-12) demonstrating significant skin inflammation inhibition, were isolated from a marine-derived fungus identified as Aspergillus sp. FAZW0001. The structural elucidation and configurational reassessments of compounds 1-5 were established through comprehensive spectral analyses, with their absolute configurations determined via single crystal X-ray diffraction using Cu Kα radiation, Marfey's method, and comparison between experimental and calculated electronic circular dichroism (ECD) spectra. Compounds 1, 2, and 8 exhibited significant anti-inflammatory activities in Propionibacterium acnes (P. acnes)-induced human monocyte cell lines. Compound 8 demonstrated the ability to down-regulate interleukin-1β (IL-1β) expression by inhibiting Toll-like receptor 2 (TLR2) expression and modulating the activation of myeloid differentiation factor 88 (MyD88), mitogen-activated protein kinase (MAPK), and nuclear factor κB (NF-κB) signaling pathways, thus reducing the cellular inflammatory response induced by P. acnes. Additionally, compound 8 showed the capacity to suppress mitochondrial reactive oxygen species (ROS) production and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome activation, thereby reducing IL-1β maturation and secretion. A three-dimensional quantitative structure-activity relationships (3D-QSAR) model was applied to compounds 5-12 to analyze their anti-inflammatory structure-activity relationships.

Objective:To investigate the risk factors of acute respiratory distress syndrome(ARDS)after traumatic hemorrhagic shock.Methods:This was a retrospective cohort study of 314 patients with traumatic hemorrhagic shock at Trauma Medicine Center,Peking University People's Hospital from De-cember 2012 to August 2021,including 152 male patients and 162 female patients,with a median age of 63.00(49.75-82.00)years.The demographic data,past medical history,injury assessment,vital signs,laboratory examination and other indicators of these patients during hospitalization were recorded.These patients were divided into two groups,ARDS group(n=89)and non-ARDS group(n=225)ac-cording to whether there was ARDS within 7 d of admission.Risk factors for ARDS were identified using Logistic regression.The C-statistic expressed as a percentage[area under curve(AUC)of the receiver operating characteristic(ROC)curve]was used to assess the discrimination of the model.Results:The incidence of ARDS after traumatic hemorrhagic shock was 28.34％.Finally,Logistic regression model showed that the independent risk factors of ARDS after traumatic hemorrhagic shock included male,histo-ry of coronary heart disease,high acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score,road traffic accident and elevated troponin Ⅰ.The OR and 95％confidence intervals(CI)were 4.01(95％CI:1.75-9.20),5.22(95％CI:1.29-21.08),1.07(95％CI:1.02-1.57),2.53(95％CI:1.21-5.28),and 1.26(95％CI:1.02-1.57),respectively;the P values were 0.001,0.020,0.009,0.014,and 0.034,respectively.The ROC curve was used to analyze the value of each risk factor in predicting ARDS.It was found that the AUC for predicting ARDS after traumatic hemor-rhagic shock was 0.59(95％CI:0.51-0.68)formale,0.55(95％CI:0.46-0.64)for history of coronary heart disease,0.65(95％CI:0.57-0.73)for APACHE Ⅱ score,0.58(95％CI:0.50-0.67)for road traffic accident,and 0.73(95％CI:0.66-0.80)for elevated troponin Ⅰ,with an overall predictive value of 0.81(95％CI:0.74-0.88).Conclusion:The incidence of ARDS in pa-tients with traumatic hemorrhagic shock is high,and male,history of coronary heart disease,high APACHE Ⅱ score,road traffic accident and elevated troponin Ⅰ are independent risk factors for ARDS after traumatic hemorrhagic shock.Timely monitoring these indicators is conducive to early detection and treatment of ARDS after traumatic hemorrhagic shock.

Objective To investigate the neurobehavioral development of young children aged 24 to 60 months in Shunde and explore the factors influencing the development of young children and provide reference for the interven-tion of neurobehavioral development delays in young children.Methods A retrospective cohort study was used to enroll the young children who were initially screened by the Pediatric Neuropsychological Developmental Scale(Pe-diatric Heart Scale)with a score of ≤85 was included in the study.With a score of ≤85,the young children might be at risk of developmental delays,and needed to be further diagnosed by the GESELL Developmental Diagnostic Scale,the basic information of the young children and their mothers at the time of birth were investigated,as well as basic information about the young children at the time of completing the GESELL Developmental Diagnostic Scale was collected.Results A total of 271 young children were included,196 males and 75 females.Young children had the lowest developmental quotient(DQ)in the language domain among the five domains(P＜0.001).Multiple lin-ear regression models showed:compared with girls,the language domain DQ of boys decreased by 5.321 points(P=0.049,95％CI:-10.620--0.021),and the personal-social domain DQ decreased by 4.474 points(P=0.023,95％CI:-8.316--0.631).Compared with young children via natural vaginal delivery(NVD),the gross motor domain DQ of young children via caesarean section(CS)decreased by 4.890 points(P=0.008,95％CI:-8.499--1.281),the fine motor domain DQ decreased by 3.373 points(P=0.037,95％CI:-6.532--0.213),the language domain DQ decreased by 7.621 points(P=0.004,95％CI:-12.826--2.416),per-sonal-social domain DQ decreased by 6.232 points(P=0.001,95％CI:-10.006--2.457).The results of bi-nary logistic regression models showed,compared with young children via NVD,the risk of gross motor domain retar-dation in young children increased(OR=1.763,95％CI:1.003-3.100),the risk of fine motor domain retardation increased(OR=2.217,95％CI:1.235-3.980),the risk of language domain retardation increased(OR=3.306,95％CI:1.080-10.124).Conclusion Young children with suspected neurobehavioral delays were more likely to have delayed development in language domain than in other domains,boys had lower DQ in language domain and personal-social domain than girls,and the development of young children via CS was slower than that via NVD.Fo-cus should be on the language development of young children especially on the language and personal-social devel-opment of boys.Carefully chose delivery way.Focus should be placed on assessment of young children's comprehen-sive neurobehavioral development in early time.

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.
