Nutritional risk and its correlation with related indexes in inpatients with aplastic anemia / 公共卫生与预防医学

Objective To investigate the nutritional status in patients with aplastic anemia (AA), and to analyze the influencing factors. Methods A retrospective analysis was performed on the clinical data of 152 patients with AA admitted to West China Hospital between March 2019 and March 2022. The nutritional status of all patients was screened by Nutritional Risk Screening 2002 (NRS2002). According to the screening criteria, the patients were divided into control group (46 cases, total NRS2002 score 0.05). The proportion of SAA cases in the malnutrition risk group was significantly higher than that in the control group. The levels of Alb and UIBC in the malnutrition risk group were significantly lower than those in the control group, while the levels of SF, SI and TSAT were higher than those in the control group. In addition, the levels of SF, SI and TSAT in SAA patients were higher than those in NSAA group (P<0.05). Logistic regression analysis showed that high levels of SF, SI and TSAT, and high proportion of SAA cases were risk factors of malnutrition in AA patients (P<0.05). The incidence of adverse prognosis in the malnutrition risk group was significantly higher than that in the control group, and the difference was statistically significant (P < 0.05). Conclusion Patients with AA have a higher risk of malnutrition, and high levels of SF, SI and TSAT are risk factors for malnutrition. The greater the risk of malnutrition, the more severe the poor prognosis.

Simultaneous determination of content of eight components in Caesalpinia decapetala by UPLC-MS/MS / 中国中药杂志

The present study established the ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method for simultaneous determination of the content of eight major active components in Caesalpinia decapetala and performed the quality evaluation of C. decapetala from different habitats with the chemical pattern recognition. The analysis was carried out on a Waters BEH C_(18) column(2.1 mm×100 mm, 1.7 μm) at 40 ℃, with the mobile phase of water containing 0.1% formic acid(A) and acetonitrile containing 0.1% formic acid under gradient elution, the flow rate of 0.3 mL·min~(-1), and the injection volume of 1 μL. The electrospray ionization(ESI) source in the negative mode and multiple reaction monitoring(MRM) were used for MS quantitative analysis. The content results were analyzed by the hierarchical cluster analysis(HCA) and principal component analysis(PCA) for the evaluation of the quality difference. Eight components showed good linear relationships within their respective concentration ranges(r>0.999), with the average recoveries of 96.85%-103.4% and RSD of 0.52%-2.8%. The analysis results showed that the quality of samples from different batches was different. The samples were classified into three clusters by HCA and PCA. The method is simple, sensitive, accurate, and efficient, and can be used for the quality evaluation of C. decapetala.

Optimization practice of fixed number package management of medical consumables based on SPD management mode / 中华医院管理杂志

The fixed number package management of medical consumables is an important content of SPD management mode. In the process of medical low-value consumables management, hospitals are generally faced with the problems of frequent access and low matching between push quantity and actual use quantity, resulting in complicated access operations of medical staff, shortage or hoarding of consumables and so on. In order to reduce the times of taking and using consumables and improve the comfort of medical staff, the authors dynamically adjusted the content and push quantity of fixed number packages according to the historical use data. The results showed that the adjusted fixed number setting could significantly reduce the average daily access times of medical staff, and reduce the probability of out of stock and hoarding.

A study on the association between the infant anemia and the utilization of maternal and child health services in ethnic minorities gathering in poverty-stricken rural areas of two provinces in Western China / 中华预防医学杂志

In this study, 1 065 infants and young children aged 24 months below in ethnic minorities gathering in poor rural areas in poor rural areas of Liangshan Yi Autonomous Prefecture of Sichuan Province and Gannan Tibetan Autonomous Prefecture of Gansu Province were investigated for their anemia status from October to November 2014, and the association between anemia and the utilization of maternal and child health services was analyzed. The prevalence of anemia in this area was 52.68%(561/1 065). After the adjustment of socio-demographic characteristics of mothers and infants, compared with infants aged 2-5 months, Han ethnic group, and infants whose mother was not anemic, the OR(95%CI) values of infant anemia for infants aged 6-12 months, 13-8 months, 19-24 months, ethnic minorities group, and infants whose mother was anemic were 11.65 (7.09-19.14), 9.91 (5.99-16.38), 5.87 (3.39-10.16), 1.55 (1.10-2.18) and 1.52 (1.14-2.04), respectively; Compared with infants whose child examination times not up to standard, and who were not only non-hospital delivered but also received inadequate number of inoculation, the OR (95%CI) values of infant anemia for infants whose child examination times up to standard, and who were not only hospital delivered but also received adequate number of inoculation were 0.60 (0.38-0.94) and 0.71 (0.52-0.98), respectively. The infants anemia is associated with the utilization of maternal and child health services.

Introduction and applications of bacteriophage polysaccaride depolymerases / 上海交通大学学报（医学版）

With the rising detection rate of strains with extensive drug resistance clinically, there is an increasingly urgent need of novel anti-microbial agents. More and more researchers put emphasis on bacteriophage therapy and have made great progress in this field. A large number of studies showed that some bacteriophages could produce enzymes which killed the host bacteria by degrading polysaccharides in their extracellular polymeric substances (EPS). This review introduces the classification of phage polysaccharide depolymerases and their action mode, the methods to determine whether the phage produces depolymerases, and their applications in anti-bacterial treatment, biofilm degradation and bacterial capsule typing.
