Objective To compare the application value of different nutritional assessment tools for peritoneal dialysis patients.Methods A total of 147 patients who were hospitalized for peritoneal dialysis in The Second Affiliated Hospital of Naval Medical University between Oct.2022 and Oct.2023 were enrolled by convenience sampling method.The nutritional assessment was carried out by using 3 assessment tools,including 7-point subjective global assessment(7-SGA),malnutrition inflammation score(MIS)and controlling nutritional status(CONUT).Correlation analyses were conducted between the nutritional assessment results and anthropometric measurements and blood biochemical indexes.Results The incidence of malnutrition assessed by 7-SGA,MIS,and CONUT were 53.74%(79/147),48.30%(71/147),and 76.19%(112/147),respectively.Both 7-SGA and MIS assessment revealed that the incidence of malnutrition in peritoneal dialysis patients＞60 years old was significantly higher than that in patients≤60 years old(both P＜0.01).Grouped by 7-SGA results,the body mass index(BMI),skeletal muscle mass,skeletal muscle mass index,phase angle,grip strength,upper arm circumference,upper arm muscle circumference,skinfold thickness,albumin and prealbumin levels in malnourished peritoneal dialysis patients were significantly lower than those in well-nourished peritoneal dialysis patients(all P＜0.05).The 7-SGA score was negatively correlated with age(P＜0.05),and was positively correlated with BMI,skeletal muscle mass,skeletal muscle mass index,phase angle,grip strength,upper arm circumference,upper arm muscle circumference,skinfold thickness,albumin,prealbumin,total protein,creatinine,and hemoglobin(all P＜0.05).Conclusion The incidence of malnutrition in peritoneal dialysis patients varies with the assessment tools used.7-SGA score has high correlation with anthropometric and blood biochemical indexes,and is effective,reliable,and practical.It is a good tool for nutritional assessment in patients undergoing peritoneal dialysis.

Objective:To describe the incidence, diagnosis rate, treatment rate and treatment pattern of hyperkalemia, and serum potassium retesting rate among hyperkalemia patients in the emergency department.Methods:Data were derived from Military Data Center for Rational Use of Drugs. Patients who accessed emergency medical services (≥18 years old) with record(s) of serum potassium between 2015 and 2017 were included. The data of laboratory test, diagnosis, and treatment were analyzed. The main outcomes included the incidence of hyperkalemia, the diagnosis rate, the treatment rate, treatment pattern and the 7-day retesting rate.Results:A total of 1 039 245 patients who met the above criteria were included, of whom, 36 615 (3.52%) had at least one hyperkalemia event. Among the emergency patients with chronic kidney disease, heart failure, diabetes mellitus and hypertension, the proportions of patients who experienced hyperkalemia were 47.69%, 29.13%, 21.69% and 10.16%, respectively. The diagnosis rate of emergency hyperkalemia patients was 9.23%. The overall hyperkalemia treatment rate was 42.1%. Insulin + glucose injection was the most commonly used therapy for emergency hyperkalemia patients. The overall serum potassium retesting rate within 7 days was 28.8%.Conclusions:Hyperkaliemia is more common and more severe in patients with chronic kidney disease, heart failure, diabetes and hypertension. The diagnosis rate and retesting rate of hyperkalemia are low, suggesting that the identification and management of hyperkaliemia in emergency patients should be strengthened.

OBJECTIVE： To evaluate the effects of clinical pharmacist-led ischemic stroke management， and to provide reference for chronic disease management. METHODS： Totally 184 patients with ischemic stroke who were hospitalized in neurology department of the First Hospital of Hebei Medical University from May to August 2018 were included prospectively， and then divided into control group （92 cases） and intervention group （92 cases） by random number method. Control group did not receive clinical pharmacist intervention. In the intervention group， clinical pharmacists were the leader in the pharmaceutical care during the hospitalization， the medication education at discharge， and pharmacy follow-up after discharge. The rate of medication compliance （antiplatelet drugs， antihypertensive drugs， hypoglycemic drugs and lipid-lowering drugs） and the rate of secondary prevention and control indicators of ischemic stroke， such as blood pressure， blood glucose [glycated hemoglobin （HbA1c）] and blood lipid [low-density lipoprotein cholesterol （LDL-C）] were investigated between 2 groups at 6 months after discharge. The incidence of adverse drug reaction and the rate of rehospitalization were compared between 2 groups at 6 months after discharge. RESULTS： The number of patients in the intervention group and the control group was 84 and 82， respectively. At 6 months after discharge， the compliance rate of antiplatelet drugs in the intervention group was 96.43％， which was higher than 95.13％ of control group， but the difference was not statistically significant. The good compliance rates of antihypertensive drugs， hypoglycemic drugs and lipid-lowering drugs in the intervention group were 92.86％， 91.67％ and 77.38％， which were higher than 78.57％， 69.70％ and 60.98％ of control group， with statistical significance （P＜0.05）. The qualified rate of index of blood pressure was 89.29％ in intervention group， which was higher than 76.79％ of control group， but the difference was not statistically significant. The qualified rates of HbA1c and LDL-C in the intervention group were 80.56％ and 66.67％， which were higher than 57.58％ and 48.785 of control group， with statistical significance （P＜0.05）. The incidence of total adverse drug reactions in the intervention group was 15.48％， which was lower than 20.73％ of control group， but the difference was not statistically significant. The total rehospitalization rate in the intervention group was 7.14％， which was lower than 17.86％ of control group， the difference was statistically significant （P＜0.05）. CONCLUSIONS： The management of ischemic stroke patients with clinical pharmacists as the leading factor can improve the patient’s medication compliance， improve the qualified rate of secondary prevention and control indicators of ischemic stroke， and reduce the rate of rehospitalization.

Aim To analyze the expression of phosphatidylethanolamine-binding protein(PEBP) and ERK in critical brain regions of psychological dependence rats.Methods Morphine-induced rats conditioned place preference(CPP) model was established to mimic different stages of morphine psychological dependence, during which PEBP expression and ERK activity were assayed in different brain regions.Results PEBP expression in hippocampus, prefrontal cortex, striatum and nucleus accumbens showed no change at three stages of psychological dependence.However, ERK activity increased notably in prefrontal cortex on CPP formation, and decreased remarkably in hippocampus on CPP reinstatement.Conclusions The formation and retrieval of associated memory between morphine effects and environment involve different neural circuits, in which ERK activity is critical, and PEBP might not be involved in such a memory-related ERK regulation.

Objective To investigate the presence, biological features, and clinical significance of myeloid-derived suppressor cells (MDSCs) in breast cancer patients.Methods Eighty-four cases of breast cancer, 37 cases of benign breast tumor and 21 cases of healthy individuals were included in this study. Samples of peripheral blood (2ml ) were collected, and in the breast cancer patients, blood samples were taken both before and after treatment.Flow cytometry using anti-CD11b, CD33, CD14 and HLA-DR antibody was conducted to identify the unique membrane markers of MDSCs, and statistical analysis was performed to explore the relationship between MDSCs and clinical factors.Cell isolation and in vitro assay were used to test T cell function.Res ult s CD11b+CD33+CD14-MDSCs were present in the blood of breast cancer patients, and these MDSCs were histologically of mononuclear cells.Cell proliferation assay confirmed that MDSCs inhibited proliferation of homologous T cells in vitro.MDSCs levels in patients with breast cancer, benign disease and the health control were (15.93±3.17)%, (8.92±4.42)% and (5.02±2.75)%, respectively, with a statistically significant difference ( P<0.001) between breast cancer patients and the other subjects (patients with benign lesions and healthy controls).The expression level of MDSCs in patients with breast cancer was associated with surgical treatment, but not with age, disease stage, lymph node metastasis, ER or PR expression.MDSCs levels were significantly lower in post-operative patients[(7.83± 3.78) %] than the (15.37±2.49) % in patients before surgery (P<0.001).Conclusions The results of this study demonstrate that MDSCs are present in the peripheral blood of breast cancer patients and the level of MDSCs is associated with surgical treatment.Our findings suggest that CD11b+CD33+CD14- MDSCs are likely involved in breast cancer initiation and development, and may become a novel biomarker to facilitate diagnosis and to predict clinical outcomes of breast cancer.

Objective To study the phosphorylation mode of extracellular regulated kinase( ERK)induced by acute and chronic morphine treatment on Chinese hamster ovary( CHO)cells expressed withμopioid receptors. Methods The time course of ERK phosphorylation 1 h and 36 h after morphine exposure as well as naloxone-precipitated withdrawal was detected by immunobloting. Results A transient enhancement of ERK phosphorylation was induced by 1 μmol · L-1 morphine with the peak effect at 5 min(P〈0. 01),and the effect was dose-dependent. No difference in ERK phosphorylation was found after 36h of treatment with 10 μmol · L-1 morphine compared with the control. However,5 or 10 min-naloxone precipitation induced remarkable decrease in ERK phosphorylation compared with the control(P〈0. 01). Conclusion Different changes of ERK phosphorylation were found under acute and chronic morphine treatment and naloxone precipitation,indicating a compensation of ERK related pathway induced byμ opioid receptors.

Background and Purpose:In recent years,along with marked rise in the incidence of lung cancer,the incidence of brain metastasis from lung cancer has increased year by year.The main treatment strategy of lung cancer with brain metastasis is irradiation,while so far there are only few researches concerning chemotherapy combined with radiotherapy for these patients.The aim of this study is to evaluate the therapeutic effect,survival rate and toxicity of chemotherapy with VM_(26)+DDP regimen given concurrently with whole-brain radiotherapy in lung cancer with brain metastasis.Methods:From Sep.2000 to Oct.2001,forty-one patients with lung cancer with brain metastasis were divided randomly into two groups: 20 patients(14 male,6 female) received concurrent chemoradiotherapy(chemoradiotherapy group),the other 21 patients(14 male,7 female) received only radiotherapy(radiotherapy group).In the chemoradiotherapy group,the average age was 50 years with range 40 to 70 years,16 patients were non-small-cell lung cancer,4 patients were small-cell lung cancer.In the radiotherapy group,the average age was 52 years with range 40 to 73 years and 19 patients were non-small-cell lung cancer,2 patients were small-cell lung cancer.For both groups,the same radiation technique was given with conventional fraction.Radiotherapy was delivered by 6MV.Fractionations of 3Gy/fraction/day was delivered 10Gy/5 factions/week.The total dose was 30Gy/10Fr/2W.For chemoradiotherapy group,the patients were also given concurrent chemotherapy(VM_(26) 60mg/m~(2)/ day iv on days 1-3,cisplatin 60 mg/m~(2) iv on the 1~(st)day).Results:The response rate and complete response in the chemoradiotherapy group was significantly higher than that in the radiotherapy group(75% ?? 38.10%,P
