OBJECTIVE:
To investigate the transfusion and infusion warmer manufacturers, combine the use failures to analyze adverse events, and provide support for enterprise risk management and clinical safe use.
METHODS:
The sentinels from 7 manufacturing enterprises and 11 medical institutions that participated in Shandong Province's key monitoring program during the "14th Five-Year Plan" period were targeted. This was done by understanding the equipment's principles, structures, and quality control. Additionally, real-world data from January 2019 to December 2023 were collected to count adverse events.
RESULTS:
During production, there are risks in switching power supply stability and solder joint firmness. Fifteen kinds of faults occurred during use, and common faults such as inability to heat, unable to turn on the machine, and bubbles in the infusion tube accounted for more than 80%.
CONCLUSION
There are many risk points and failures for transfusion and infusion warmers, so enterprises should improve processes and quality control to address risks, and medical institutions should formulate specifications and maintenance plans to provide targeted theoretical basis for supervision.

Objective To analyze the expression level of ATP5A1 in gastric carcinoma and its influence on the prognosis of the patients and glucose metabolism in the tumor cells.Methods We retrospectively analyzed the data of 115 patients undergoing radical resection of gastric carcinoma in our hospital from February,2013 to November,2016.ATP5A1 expression in the surgical specimens were detected using immunohistochemistry,and the long-term prognosis of the patients with high(n=58)and low ATP5A1 expression(n=57)were analyzed.In gastric carcinoma MGC803 cells,the effects of lentivirus-mediated ATP5A1 knockdown or overexpression on glucose metabolism were investigated.We also observed the growth and glucose metabolism of xenografts derived from MGC803 cells with ATP5A1 knockdown or overexpression in nude mice.Results ATP5A1 was significantly overexpressed in gastric carcinoma tissues in close correlation with blood CEA and CA19-9 levels,pathological grade,T stage and N stage(P<0.05).ATP5A1 overexpression was an independent risk factor for a significantly lowered 5-year survival rate of patients with gastric carcinoma(P<0.05).ROC curve analysis demonstrated the predictive value of high ATP5A1 expression for the patients'prognosis(P<0.001).In MGC803 cells,ATP5A1 overexpression significantly up-regulated cellular glucose uptake and lactate production and increased the protein levels of HK2,PFK1,and LDHA(P<0.05),while ATP5A1 knockdown produced the opposite changes(P<0.05).In the tumor-bearing mice,overexpression of ATP5A1 increased glucose metabolism of the tumor cells and promoted tumor growth(P<0.05).Overexpression of ATP5A1 promoted the expressions of p-JNK and p-JUN in MGC803 cells(P<0.05),and the JNK inhibitor SP600125 significantly inhibited the enhancement of cellular glucose metabolism induced by ATP5A1 overexpression(P<0.05).Conclusion High ATP5A1 expression in gastric cancer is associated a poor long-term prognosis of the patients,and its effect is mediated at least partly by promoting glucose metabolism of the cells through the JNK/JUN pathway.

ObjectiveTo explore the correlation between the content of 4 functional components in Codonopsis pilosula roots from different areas and soil factors, and thereby to lay a theoretical basis for soil ecological regulation and improvement of quality of C. pilosula roots. MethodThe content of lobetyolin, atractylenolide Ⅲ, alcohol extract, and polysaccharides, as well as soil fertility and 16 soil factors in 24 batches of samples from different producing areas were determined. Principal component analysis (PCA) and Pearson's correlation analysis were used to explore the key soil factors leading to the variation of chemical component content in C. pilosula roots. ResultThe content of lobetyolin and atractylenolide Ⅲ in samples from Longxi was the highest, and the content of polysaccharides peaked in samples from Huguan. The content of lobetyolin was in positive correlation with soil total nitrogen, total phosphorus, total potassium, alkali-hydrolyzable nitrogen, and available potassium (P<0.01), as well as soil organic matter, pH, available manganese, and available zinc (P<0.05). There was a positive correlation between pH and atractylenolide Ⅲ content (P<0.05). Soil total potassium was in positive correlation with alcohol extract and polysaccharide content (P<0.01). Soil available zinc was positively correlated with alcohol extract and the polysaccharide content (P<0.05). Sample sites with higher PCA scores were Pingshun, Huguan, and Longxi, which were significantly positively correlated with the content of polysaccharides in C. pilosula roots in different habitats. ConclusionThe content of functional components in C. pilosula roots can be improved by raising soil organic matter content and applying specific fertilizers.

Objective:To analyze the effects of prescription reviews of key monitored drugs using the drug regulatory platform in a district of Shanghai, and the influencing factors for the rate of unqualified prescriptions.Methods:A drug regulatory platform in a district in Shanghai began to implement prescription reviews since June 2018, extracting the reviewed prescriptions of all key monitored drugs and related information from June to December. Taking the unqualified rate of prescription in June as the baseline data, the χ2 test and the logistics regression model were used for data analysis. Results:From June to December 2018, clinical pharmacists reviewed 19 084 outpatient and emergency prescriptions and 10 607 inpatient prescriptions. The unqualified rates of outpatient and emergency prescriptions and inpatient prescriptions dropped from 16.52% and 23.28% in June to 4.45% and 13.80% in December, respectively. Logistics regression analysis showed that the rate of unqualified reviews of outpatient and emergency prescriptions was lower than that of inpatient prescriptions, and the rate of unqualified prescriptions in hospital was significantly lower than that in community health service centers; the rate of unqualified prescriptions for auxiliary drugs and nutritional drugs was significantly lower than that of antibacterial drugs.Conclusions:The prescription reviews of key monitored drugs can effectively promote the rational use of drugs. In the future, it is recommended to strengthen technical support for community health service centers and professional training for clinicians and pharmacists.

In order to evaluate the use of transendoscopic miniature ultrasonic probe (TEMP) in the diagnosis of gastric submucosal tumor, 18 patients were investigated. The results obtained by TEMP were compared with those of gastroscopy, and endoscopical ultrasonography (EVS). The result showed that among those 18 patients, gastric submucosal leiomyomas, were common and accounted for 88.9%. Most of them were intramural. The diagnostic accuracy of TEMP for the size of tumor and gastric submucosal tumor was 88.9% and 100% respectively. Which were much higher than those of gastroscopy (33.3% and 61.1% respectively). The sonogrophic characteristics of gastric submucosal tumors in TEMP imaging were related to the nature of the tumors, hut the common manifestations were that all the tumors were hypoechoic under the hyperechoic mucosal layer with clear bell shaped origin, and usually appeared as round or nearly round intragastric eminence. It is concluded that the selective use of TEMP has great value in the diagnosis of gastric submucosal turmor, especially for those lesions which were small and difficult to be detected by EUS.
