Evaluation and improvement of blood station quality management system: based on external audit / 中国输血杂志

【Objective】 To identify the main unqualified items in the external audit of blood station quality management system (referred to as external audit), in order to take necessary measures to continuously improve the quality system. 【Methods】 Unqualified items(data) in the national and Shandong provincial blood safety technical audits (referred to as national and provincial audits) and four blood station blood safety technical joint audits (referred to as inter station mutual audits) from 2017 to 2019 were collected and analyzed by Excel and Pareto curves (graphs). Corresponding corrective and preventive measures were developed and implemented, and then tracked and evaluated by the quality management department three months after the external audit to verify their effectiveness. 【Results】 In a total of 7 external audits of blood station quality management system that our blood station has participated in over the past 3 years (including 2 national audits, 2 provincial audits, and 3 inter station mutual audits), the main unqualified terms were "12 monitoring and continuous improvement" 11.90% (15/126), "13 blood donation services" 11.90% (15/126), "06 equipment" 10.32% (13/126), "11 records" 10.32% (13/126), "03 organization and personnel" 8.73% (11/126), "15 blood preparation" 7.94% (10/126), "08 safety and health" 7.14% (9/126), and "14 blood testing" 7.14% (9/126). Among them, "monitoring and continuous improvement" ranked first in two national audits and two provincial audits, with 16.67% (5/30) and 14.71% (5/34), respectively, and was 8.06% (5/62) in inter station mutual audit, and the difference between the three kinds of audits was not statistically significant (P>0.05). "Records" accounted the highest proportion in inter station mutual review of 19.35% (12/62), while was respectively 0 and 2.94% (1/34) in national and provincial audits, with statistically significant difference between the three kinds of audits (P<0.05). 【Conclusion】 External audit against unqualified items is important for quality improvement. By analyzing the unqualified terms, taking corresponding measures to improve weak links, and evaluating the effectiveness of those measures, it can effectively ensure the effective operation of blood station quality management system.

Role of selenoprotein M knockdown in the melatonin antagonism of nickel-induced apoptosis and endoplasmic reticulum stress in mouse heart / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

The aim of this study was to investigate the role of selenoprotein M (SelM) in endoplasmic reticulum stress and apoptosis in nickel-exposed mouse hearts and to explore the detoxifying effects of melatonin. At 21 d after intraperitoneal injection of nickel chloride (NiCl2) and/or melatonin into male wild-type (WT) and SelM knockout (KO) C57BL/6J mice, NiCl2 was found to induce changes in the microstructure and ultrastructure of the hearts of both WT and SelM KO mice, which were caused by oxidative stress, endoplasmic reticulum stress, and apoptosis, as evidenced by decreases in malondialdehyde (MDA) content and total antioxidant capacity (T-AOC) activity. Changes in the messenger RNA (mRNA) and protein expression of genes related to endoplasmic reticulum stress (activating transcription factor 4 (ATF4), inositol-requiring protein 1 (IRE1), c-Jun N-terminal kinase (JNK), and C/EBP homologous protein (CHOP)) and apoptosis (B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), Caspase-3, Caspase-9, and Caspase-12) were also observed. Notably, the observed damage was worse in SelM KO mice. Furthermore, melatonin alleviated the heart injury caused by NiCl2 in WT mice but could not exert a good protective effect in the heart of SelM KO mice. Overall, the findings suggested that the antioxidant capacity of SelM, as well as its modulation of endoplasmic reticulum stress and apoptosis, plays important roles in nickel-induced heart injury.

Boosting 5-ALA-based photodynamic therapy by a liposomal nanomedicine through intracellular iron ion regulation

5-Aminolevulinic acid (5-ALA) has been approved for clinical photodynamic therapy (PDT) due to its negligible photosensitive toxicity. However, the curative effect of 5-ALA is restricted by intracellular biotransformation inactivation of 5-ALA and potential DNA repair of tumor cells. Inspired by the crucial function of iron ions in 5-ALA transformation and DNA repair, a liposomal nanomedicine (MFLs@5-ALA/DFO) with intracellular iron ion regulation property was developed for boosting the PDT of 5-ALA, which was prepared by co-encapsulating 5-ALA and DFO (deferoxamine, a special iron chelator) into the membrane fusion liposomes (MFLs). MFLs@5-ALA/DFO showed an improved pharmaceutical behavior and rapidly fused with tumor cell membrane for 5-ALA and DFO co-delivery. MFLs@5-ALA/DFO could efficiently reduce iron ion, thus blocking the biotransformation of photosensitive protoporphyrin IX (PpIX) to heme, realizing significant accumulation of photosensitivity. Meanwhile, the activity of DNA repair enzyme was also inhibited with the reduction of iron ion, resulting in the aggravated DNA damage in tumor cells. Our findings showed MFLs@5-ALA/DFO had potential to be applied for enhanced PDT of 5-ALA.

The potentially inappropriate medications among elderly patients with chronic diseases in Shanghai communities and its influence factors / 中华全科医师杂志

Objective:To investigate the potentially inappropriate medication(PIM)among elderly patients with chronic diseases in Shanghai communities and related influence factors.Method:Six community Health service Centers were choosen using stratified sampling. Total 968 elderly patients with chronic diseases who visited to the outpatient clinic of Shanghai Community Health Service Centers from July to August 2018 were included in the study. The PIM was investigated according to the 2015 Beers criteria. The χ 2 test and multivariate logistic regression model were used to analyze factors related to the PIM. Results:The survey showed that 317 elderly patients had PIM with 412 person-doses. In 134 person-doses, the PIM was unrelated to the disease; in 18 person-doses, PIM was caused by interaction of drug with disease/symptoms; in 259 person-doses PIM was related to the drugs that should be cautiously used for elderly; only in 1 person-dose the PIM was caused by the interaction between drugs. The drugs with the highest proportion of PIM were diuretics, benzodiazepines and aspirin. There were significant differences in age, kinds of diseases, kinds of drugs and times of visiting community health service centers between elderly patients with PIM and those without PIM (χ 2=42.28, 35.51, 46.47, 38.46; all P<0.05). The main PIM-related factors were age, kinds of diseases, kinds of drugs and times of visiting community health service centers. Conclusion:The study shows that the prevalence of PIM among elderly chronic diseases patients in Shanghai communities is relatively high, which is associated with the age, kinds of diseases, kinds of drugs and times of visiting community health service centers.

Covariance analysis and partial correlation analysis were conducted by SPSS17.0.Results:When watching the pictures of person communication, there were statistically significant differences in the average fixation duration of the four groups of subjects ((294.6±36.7)ms in control group, (280.0±54.0)ms in clinical high-risk group, (268.5±34.9)ms in first-episode group, and (315.7±75.7) ms in chronic group, respectively, F=3.18, P=0.027). When viewing the pictures of no person landscape, the average saccade amplitude of the four groups of subjects was significantly different (5.3±1.1) ° in control group, (4.7±1.1) ° in clinical high-risk group, (5.2±1.0) ° in first-episode group, and (4.4±1.2) ° in chronic group, respectively, F=3.37, P=0.021). The average fixation duration of chronic patients when observing person communication pictures was positively correlated with the total score of PANSS (partial correlation coefficient=0.313, P=0.039). The average fixation duration of chronic patients when observing the other two types of pictures were also positively correlated with the total score of PANSS (partial correlation coefficient=0.320, P=0.034, no person communication pictures; partial correlation coefficient=0.372, P=0.013, no person landscape pictures) . The average fixation duration of chronic patients when observing pictures of no person landscape was positively correlated with the PANSS positive symptom score (partial correlation coefficient=0.321, P=0.034). The average fixation duration of chronic patients when observing any type of picture was positively correlated with the PANSS general symptom score (person communication pictures: partial correlation coefficient=0.385, P=0.010; no person communication pictures: partial correlation coefficient=0.409, P=0.006; no person landscape pictures: partial correlation coefficient=0.465, P=0.001). In the first-episode patient, the average saccade amplitude when observing no person communication pictures was positively correlated with the PANSS positive symptom score (partial correlation coefficient=0.555, P=0.049). In the clinical high-risk group, the average saccade amplitude when observing person communication pictures was negatively correlated with the SOPS positive symptom score (partial correlation coefficient=-0.373, P=0.030). Conclusion:There are statistically significant differences of eye movement characteristics of social cognitive processing in patients with schizophrenia across different clinical stages.The average saccade amplitude is more sensitive than the average fixation duration in predicting the severity of symptoms in clinical high-risk patients.

A study of event-related potential P300 in subjects with clinical high risk of psychosis / 中国神经精神疾病杂志

Objective To investigate the characteristics of auditory P300 amplitude and latency and cognition in patients with clinical high-risk of psychosis (CHR). Method Thirty six CHR (study group) and thirty five healthy con?trols (control group) were included. Oddball paradigm and MATRICS Consensus Cognitive Battery (MCCB) were used to record auditory P300 and to evaluate the cognition, respectively. The structured interview for psychosis-risk syndromes (SIPS) was used to evaluate the clinic symptoms of patients. Result The cognition of CHR was significantly lower than healthy controls in information processing, attention/vigilance, working memory, verbal learning, visual learning, reason?ing and problem solving and social cognition (P<0.01). The study group showed decreased amplitude in Fz, Cz and Pz and delayed latency in Pz (P<0.05). P300 latency of CHR in Fz positively correlated with positive score of SOPS (r=0.544, P=0.001), while P300 amplitude positively correlated with verbal fluency (r=0.339,P=0.043). Conclusion Cogni?tion and P300 is abnormal in CHR. The correlation between P300 and clinical symptoms, cognitive dysfunction reminds that we should put more attention on the role of P300 in CHR subjects.
