Objective: To analyze characteristics of iron-deficient blood donors, implement targeted interventions, and evaluate their effectiveness, thereby providing a reference for formulating blood donor recruitment and care strategies. Methods: Based on serum ferritin (SF) test results, the apheresis platelet donors were divided into the low SF group (n=90; 45 males and 45 females) and the normal SF group (n=651; 510 males and 141 females). The results of related indicators of the two groups were compared and analyzed. Interventions for the low SF group included extending the blood donation interval to at least 45 days (group A) and oral iron supplementation combined with the extended donation interval implemented in group A (group B). Pre-intervention and post-intervention SF results were compared. Results: For both male and female donors, serum iron levels were significantly lower in the low SF group than those of the normal SF group, while the levels of transferrin, unsaturated iron binding capacity (UIBC) and total iron binding capacity (TIBC) were higher in the low SF group compared to the normal SF group. Some indicators related to red blood cells showed changes, with more evident alterations in females than in males. Twenty-eight donors in group A and 39 donors in group B completed the study after intervention. SF value in group A was (18.32±8.09) μg/L at baseline and (26.21±17.30) μg/L after intervention. Similarly, SF value in group B was (15.87±7.69) μg/L at baseline and (26.24±15.55) μg/L after intervention. In both groups, SF values after intervention were significantly higher than baseline values. However, the magnitude of change did not significantly differ between groups A and B. Conclusion: Other related indicators in blood donors with low ferritin have also experienced some changes, suggesting that some blood donors may have entered the stage of iron-deficient erythropoiesis. Extending blood donation interval facilitates the recovery of iron storage in low-ferritin apheresis platelet donors. Blood stations should develop care strategies for apheresis platelet donors, including, at a minimum, the prolonged blood donation interval for donors with low ferritin.

Medical equipment, as an important indicator of smart hospital evaluation, plays a vital role in hospital operations. To ensure the safe and efficient operation of medical equipment, a reasonable performance evaluation system is indispensable. This study introduces a platform based on Internet of Things (IoT) technology that connects medical devices and collects data, achieving standardized and structured data processing, and supporting online operational supervision. Through the Delphi method, a performance evaluation system for large medical equipment is constructed, including 4 primary indicators and 22 secondary indicators. DICOM data acquisition devices are used to achieve functions such as efficiency analysis, benefit analysis, usage evaluation, and decision-making support for medical equipment. The study is still in its early stages, and in the future, it is expected to integrate more types of equipment, achieve rational resource allocation, and significantly impact decision-making for the development of public hospitals.

Objective:To explore the differences in the clinical application of different brands of infrared ear thermometers in pediatric patients,and to guide the rational use of infrared ear thermometers.Methods:A total of 164 inpatients and outpatients who received treatment in the Children's Hospital of Zhejiang University School of Medicine from May 2023 to July 2023 were randomly selected,and three different brands of ear thermometers were used to measure the ear temperature of the children in the same measurement method.The differences in temperature and time measured by different brands of ear thermometers in children of different ages were compared.Results:The temperature and time measurements of the three ear thermometers were compared,the difference was statistically significant(F=5.007,264.988,P<0.05).The temperature of children aged≤3 months was measured by the three ear thermometers,and the difference was statistically significant(F=3.868,P<0.05).there was no difference in children aged over 3 months.Conclusion:For children of different ages,medical institutions can make choices based on the comprehensive consideration of the use cost,the speed of measurement time and other factors.For children aged over 3 months,choose product B with lower cost and faster measurement time,for children aged 0-3 months,it is recommended to choose product A with more accurate temperature measurement values.

Antipsychotic medications are commonly used to treat schizophrenia,but they can have negative effects on lipid metabolism,leading to an increased risk of cardiovascular diseases,reduced life expectancy,and difficulties with treatment adherence.The specific mechanisms by which antipsychotics disrupt lipid metabolism are not well understood.Sterol regulatory element-binding proteins(SREBPs)are important transcriptional factors that regulate lipid metabolism.Proprotein convertase subtilisin/kexin type 9(PCSK9),a gene regulated by SREBPs,plays a critical role in controlling levels of low-density lipoprotein cholesterol(LDL-C)and has become a focus of research on lipid-lowering drugs.Recent studies have shown that antipsychotic drugs can affect lipid metabolism through the SREBP/PCSK9 pathway.A deep understanding of the mechanism for this pathway in antipsychotic drug-related metabolic abnormalities will promote the prevention of lipid metabolism disorders in patients with schizophrenia and the development and application of new drugs.

A 55-year-old male patient with severe mitral valve insufficiency received long-time warfarin anticoagulation therapy after mechanical mitral valve replacement and the international standard ratio (INR) was 2.00-3.00. Because of oral ulcers, he took the water soaked with dandelion ( Taraxacum mongolicum Hand-Mass.), which was self-purchased and sun-dried, for daily drinking. Fifteen days later, the patient developed chest tightness, shortness of breath, palpitation, and fatigue, followed by nausea, vomiting, mild edema of the lower limbs, orthopnea at night, ecchymosis on the right lower limb, and black stool successively. Laboratory tests showed hemoglobin 52 g/L, red blood cell count 2.05×10 12/L. Gastrointestinal bleeding was considered, which might be related to the water soaked with dandelion drunk during warfarin therapy. Warfarin and water soaked with dandelion were stopped. The patient received symptomatic treatments including IV infusions of leukocyte-depleted red blood cell suspension 2 units (2 times in total) and esomeprazole 80 mg (twice daily), an intramuscular injection of vitamin K 1 10 mg, and oral vitamin K 1 20 mg. Two days later, the patient′s INR was 1.58, hemoglobin was 84 g/L, and red blood cell count was 2.33×10 12/L. Five days later, his INR was 1.63, hemoglobin was 104 g/L, and red blood cell count was 3.92×10 12/L.

As the dressings currently used in clinic settings unflat shape in general, they can't be fitted completely on occiput, heel, elbow, knee and other body parts unflat. This paper developed one kind of foam dressing of special shape based on local anatomy. The foam dressing is waterproof and air permeable, it can cover the wound closely enough to prevent bacteria from invasion and infection. With a saturated absorption ratio of 1: 8 or higher, it can keep the wound clean and moisture by absorbing large amounts of wound inflammatory secretions and is almost completely permeable to oxygen and carbon dioxide. Assuring safety and effect meanwhile, it has better outcomes than common dressings in the same application settings.
