OBJECTIVE:To provide reference for improving the cognition of medical staff for adverse drug reactions(ADR). METHODS:A questionnaire survey was conducted on the spot among the physicians,nurses and pharmacists with different profes-sional titles in our hospital to investigate their cognition about ADR concept,their judgment for ADR and ADR reporting,and the results were analyzed by statistical methods. RESULTS:Totally 452 questionnaires were sent out,and 439 were effectively re-ceived,with effective rate of 97.12%. In terms of correct cognition rate about ADR basic concept and the main reasons,the sur-veyed pharmacists were higher than physicians and nurses,the senior professional titles of surveyed pharmacists were higher than the intermediate and junior,the pharmacists with senior professional titles were the highest and the junior were the lowest,the dif-ferences were statistically significant(P<0.05);in terms of the proportion of certain for ADR judgment,the surveyed nurses were lower than pharmacists and physicians,the surveyed physicians with senior and intermediate professional titles were higher the ju-nior,the surveyed nurses with intermediate titles were higher than the junior,the surveyed pharmacists with senior professional ti-tles were higher than the intermediate and the junior,the differences were statistically significant(P<0.05);in terms of cognition about ADR reporting,the surveyed pharmacists were the highest and the nurses were the lowest,the differences were statistically significant (P<0.05),while in terms of the proportion of knowing ADR reporting timing limit,reporting procedures and depart-ments,the surveyed pharmacists and physicians with junior professional titles were lower than the senior and intermediate,the dif-ferences were statistically significant(P<0.05);in terms of reasons for missed ADR reporting,the proportion of consideration of the risk of causing medical disputes for doctors of the surveyed physicians was higher than pharmacists and nurses,while the sur-veyed nurses showed higher proportion for doing not understand reporting procedures,doing not reporting,thinking ADR reporting was dispensable and uncertain for ADR identification,the differences were statistically significant (P<0.05). CONCLUSIONS:Medical staff with different professional titles and occupations have different cognition about ADR basic concept,judgment and re-porting,the pharmacist are relatively good,followed by the physician and nurse,especially the nurse,and the medical staff with junior professional titles are relatively poor. It is necessary to strengthen ADR education and training for them,play professional ad-vantages from the pharmacist and optimize ADR reporting procedures to improve the reporting rate and quality of ADR.

OBJECTIVE: To analyze the effects of Astragalous Injection on oxidative stress and micro-inflammatory status in patients undergoing maintenance hemodialysis (MHD). METHODS: Sixty MHD patients were included and randomized into treatment group and control group, with another 10 healthy volunteers as normal control. The patients in the treatment group were treated with Astragalous Injection and the patients in the control group were treated with normal saline for 12 weeks. A spectrophotometric method was used for the measurement of plasma concentrations of oxidative parameters including advanced glycation end products (AGEs), advanced oxidation protein product (AOPP), malondialdehyde (MDA) and vitamin E (Vit E). The content of C-reactive protein (CRP) was evaluated by enzyme-linked immunosorbent assay. RESULTS: Compared with the normal control group, the plasma levels of AGEs, AOPP, MDA and CRP were significantly increased, while plasma level of Vit E was significantly decreased in MHD patients ( P<0.01). After Astragalous Injection treatment, the plasma levels of AGEs, AOPP, MDA and CRP were decreased as compared with the control group ( P<0.01), while there was no significant difference in plasma Vit E level between the treatment group and control group. CONCLUSION: There exist oxidative stress and micro-inflammation in MHD patients. Astragalous Injection can ameliorate the accumulation of oxidative products and micro-inflammatory status, but it has no significant effect on plasma Vit E level.

Objective:To investigate the effects of Xiaoyu-Jiangzhi capsules on blood lipid, carotid artery atherosclerosis (CAA) and plaque in apolipoprotein E knockout (ApoE -/-) mice. Methods:The ApoE -/- mice were fed with high-fat food to establish carotid atherosclerosis model. The ApoE -/- mice were randomly by weight divided into model group, Atorvastatin group, low- and high-dose Xiaoyu-Jiangzhi capsules group. The C57BL/6cnc mice were used as control group and fed with normal diet. The Atorvastatin group was given atorvastatin suspension 1.3 mg/kg, low and high dose groups were given Xiaoyu-Jiangzhi capsule suspension 325 and 975 mg/kg, and the control group and model group were given equal volume of distilled water. The mice were gavaged with 0.1 ml/10 g body weight, once a day, and the weight of mice was recorded weekly. After 12 weeks of continuous intragastric administration, the blood lipid and liver /body weight index of the mice were measured. Carotid arteries were sliced to conduct oil red O staining and VG staining for the pathological analysis. Results:After 12 weeks of drug administration, the weight of mice in the high-dose group was significantly lower than the model group. The level of TC (25.92 ± 4.21 mmol/L vs. 30.39 ± 4.67 mmol/L) and LDL-C (7.97 ± 2.14 mmol/L vs. 10.26 ± 1.97 mmol/L) in the high-dose group significantly decreased ( P<0.05), the level of HDL-C in the low and high-dose group significantly increased ( P<0.05). The pathological results showed that after 12 weeks of administration, the carotid artery lipid deposition blockage rate in the Atorvastatin group and the high dose group were significantly smaller than the model group( P<0.05), and no vascular plaque has been formed. Conclusion:The Xiaoyu-Jiangzhi capsules could reduce LDL-C, increase HDL-C levels, reduce the constriction of arterial stenosis and slow down the formation process of carotid plaque.

Objective: To explore sarcoplasmic reticulum ryanodine receptor2 (RyR 2) expression and calcium releasing function in chronic heart failure (CHF) rabbits and to study the impact of long term valsartan treatment in relevant animals. Methods: HF model was established by volume overloading with pressure overloading in experimental rabbits. 27 rabbits were divided into 3 groups: Sham group, HF group and HF+valsartan group. n=9 in each group and the animals were treated for 7 weeks. Left ventricular structure, hemodynamic parameters, expression and functional changes of myocardiocyte sarcoplasmic reticulum RyR 2 were observed and compared among different groups. Results: Compared with Sham group, HF group had increased left ventricular mess index (LVMI), left ventricular end diastolic pressure (LVEDP) and decreased left ventricular shortening fraction, LVEF, all P<0.05. Compared with HF group, HF+valsartan group showed decreased LVMI, LVEDP and increased left ventricular shortening fraction, LVEF, all P<0.05. Sarcoplasmic reticulum RyR 2 expression and calcium releasing function were lower in HF group than Sham group, P<0.05; while they were both higher in HF+valsartan group than HF group, P<0.05. Conclusion: Long term application of valsartan could improve the cardiac function which might be related to increased myocardial sarcoplasmic reticulum RyR 2 expression and calcium releasing function in experimental CHF rabbits.

Objective:To evaluate the nutritional status of patients in intensive care unit (ICU) by using nutritional risk screening 2002 scale (NRS2002), subjective general assessment (SGA) and critical illness nutritional risk score (NUTRIC), and to compare the characteristics and applicability of three scoring tools.Methods:A cross-sectional survey was conducted. 315 patients admitted to the comprehensive ICU of Affiliated Qingdao Municipal Hospital of Qingdao University from April 2018 to July 2019 were enrolled. Basic information of patients was collected, and patients were divided into two groups with 65 years old as the standard to compare the nutritional status of patients among different genders and ages. The nutritional status of patients were assessed by NRS2002, SGA, and NUTRIC. Height, weight, body mass index (BMI), triceps skinfold thickness (TSF), upper arm circumference (AC), leg circumference (LC), and other related parameters of human nutrition were measured. Total protein (TP), albumin (Alb), prealbumin (PA), serum creatinine (SCr), blood urea nitrogen (BUN), total cholesterol (TC), triglyceride (TG), total number of lymphocytes (LYM), hemoglobin (Hb), C-reactive protein (CRP) and other blood biochemical indicators were performed. Spearman rank correlation analysis was used to analyze the correlation between the three nutrition evaluation scales and other objective nutrition parameters. Binary multivariate Logistic regression analysis was used to evaluate the influencing factors of nutritional status with three scales of patients in ICU.Results:Among 315 patients in ICU, 183 were male and 132 were female. There were 143 patients < 65 years old and 172 ≥ 65 years old. In male patients, the acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, age and BUN of patients aged ≥ 65 years old were significantly increased, and the height, weight, BMI, TSF, AC, LC, Alb and PA were significantly lowered as compared with those aged < 65 years old, while the difference in other indicators was not statistically significant. In the female patients, the APACHEⅡ score, age, SCr and BUN of the patients aged ≥ 65 years old were significantly increased, the height, Alb, PA and Hb were significantly decreased as compared with those aged < 65 years old, and the difference in other indicators was not statistically significant. The proportion of patients with nutritional risk evaluated by NRS2002 (NRS2002 score ≥ 3) was 87.62% (276/315). SGA showed that the proportion of malnourished patients (SGA was grade B or C) was 62.86% (198/315). NUTRIC showed 66.03% of patients (208/315) in high nutritional risk (NUTRIC score ≥ 5). Spearman rank correlation analysis showed that there were significant correlations among NRS2002, SGA and NUTRIC of patients in ICU ( rNRS2002 with SGA = 0.522, rNRS2002 with NUTRIC = 0.392, rSGA with NUTRIC = 0.442, all P < 0.01). Among the three assessment tools, SGA had the best correlation with blood biochemical indicators and body measurements to assess nutritional status, followed by NRS2002, and NUTRIC had the worst correlation. Binary multivariate Logistic regression showed that APACHEⅡ score, BMI, AC, BUN and TG were factors influencing NRS2002 assessment of nutritional status in ICU patients [odds ratio ( OR) were 2.535, 0.404, 1.438, 0.858, and 2.391, respectively, all P < 0.05]; APACHEⅡ score, age, weight, TP, BUN, LYM and CRP were influence factors of SGA for evaluating the malnutrition of patients in ICU ( OR values were 1.074, 1.038, 0.921, 0.947, 1.077, 1.625 and 0.991, respectively, all P < 0.05); APACHEⅡ score, age, LYM and CRP were the influence factors of NUTRIC assessment for malnutrition of patients in ICU ( OR values were 1.159, 1.049, 0.715 and 0.995, respectively, all P < 0.05). Conclusions:The nutrition status of ICU patients evaluated by NRS2002, SGA and NUTRIC was simple and easy to operate, and the positive screening rate of NRS2002 was the highest, which was suitable for patients with mild conditions in ICU. SGA is the most valuable tool to evaluate the nutritional status of ICU patients. NUTRIC has a poor correlation with objective indicators reflecting nutritional status, while its indicators are objective and easy to obtain, which is suitable for ICU patients with critical condition and unclear consciousness. Nutritional assessment tools should be integrated with the patient's gender, age, anthropometric and biochemical indicators.

OBJECTIVETo detect potential mutation of MLC1 gene in a child affected with megalencephalic leukoencephalopathy with subcortical cysts (MLC).

METHODSClinical symptoms of the patient were retrieved. Peripheral blood DNA samples from the patient, her parents and healthy controls were collected. Potential mutation of the MLC1 gene was detected by polymerase chain reaction and Sanger sequencing.

RESULTSThe patient presented with severe motor developmental delay and a giant skull. Magnetic resonance scan showed diffuse white matter swelling in bilateral hemispheres. DNA sequencing identified a novel homozygous c.177-c.180delC mutation of the MLC1 gene. The parents of the patient both carried a heterozygous mutation c.177-c.180delC but had a normal phenotype.

CONCLUSIONA novel MLC1 mutation c.177-c.180delC has been identified in a patient with MLC. The mutation is presumably disease-causing and has derived from parents who are both carriers.

Objective To investigate the prevalence and risk factors of chronic kidney disease (CKD) in middle-aged and older adult population in Shanghai Pudong New District.Methods Two thousand residents aged 45 years and above were randomly selected for questionnaire survey and health check-up in Shanghai Pudong New District from July 2006 to October 2010.The laboratory examinations were also performed including the urine routine,urinary protein to creatinine ratio,serum creatinine,blood glucose and lipids.The glomerular filtration rate (eGFR) was estimated by simplified Chinese MDRD (modification of Diet in Renal Disease) equation.SPSS 13.0 statistical software was used for statistical analysis.Results Among 1905 residents who completed survey and examinations,the adjusted prevalence of albuminuria was 12.0％ (95％ CI:0.105-0.135) and of eGFR less than 60 ml · min-1 · 1.73 m-2 was 1.9％ (95 ％ CI: 0.172-0.213).The prevalence of CKD was 12.6％ (95 ％ CI: 0.112-0.142).Logistic regression analysis revealed that age (OR =1.043),hypertension (OR =2.272),diabetes mellitus (OR =1.233)and hyperuricemia (OR =1.003)were independently associated with CKD.Conclusions The prevalence of CKD in adult residents (≥45 years) from Shanghai Pudong New District is high.It is necessary to carry out early screening and to intervene risk factors of CKD in middle-aged and older residents.

Objective: To explore the changes of protein expression and activity of calcium/calmodulin-dependent protein kinase-II (CaMK-II) in myocardium nucleus and sarcoplasmic reticulum in experimental rabbits with heart failure (HF).
Methods: A total of 16 rabbits were divided into 2 groups: Sham group and HF group, the HF model was established by volume overload plus pressure overload.n=8 in each group and all animals were treated for 7 weeks. Left ventricular structure, hemodynamic parameters and protein expression and activity of CaMK-II in myocardium nucleus and sarcoplasmic reticulum were examined and compared between 2 groups.
Results: Compared with Sham group, HF group presented increased left ventricular mass index (LVMI) (1.32 ± 0.06) g/kg vs (3.61 ± 0.09) g/kg, LVEDP (-1.50 ± 0.50) mmHg vs (23.00 ± 2.37) mmHg, allP<0.05; while decreased left ventricular shorten fraction (37.83 ± 3.58) % vs (17.38 ± 3.13) % and LVEF (71.92 ± 4.56) % vs (38.50 ± 6.07) %, allP<0.05. The protein expression and activity of CaMK-II were both higher in HF group than Sham group, allP<0.05.
Conclusion: Increased protein expression and activity of CaMK-II in myocardium nucleus and sarcoplasmic reticulum might be one of the mechanisms for HF occurrence in experimental rabbits.

The elderly represent a segment with a high incidence of pain.Consciousness impairment and language dysfunction increase the difficulty of pain assessment.At the same time, a lack of understanding of neuropathic mechanisms and assessment scales often leads to inappropriate pain assessment in the elderly with dementia.This article reviews the relationship between dementia and pain, pain assessment protocols and the use of scales in the elderly with dementia.
