Objective To analyze the configuration of testing equipment in blood testing laboratories of blood stations in Shandong Province to facilitate to optimize equipment configuration for blood testing laboratories.Methods Questionnaires were distributed to obtain information on the number,the proportions of domestic and imported equipment,the usage time and the number of annual sample detection for the testing equipment of 17 blood testing laboratories(one laboratory from blood center and 16 laboratories from central blood stations)in Shandong Province,including the equipment for blood group testing,alanine aminotransferase(ALT)testing,sample adding of enzyme-linked immunosorbent assay(ELISA),ELISA micro-plate processing and nucleic amplification test(NAT).The testing equipment in the laboratories with different sizes were analyzed in terms of substitutability,localization,number of annual sample detection and average usage time.Results The blood group and ALT testing equipment had low substitutability;the imported equipment for ALT testing and ELISA sample adding had high proportions;the numbers of yearly sample detection of the equipment for ELISA sample adding,ELISA microplate processing and NAT rose significantly with the increase of laboratory sizes(P＜0.05);the equipment for ELISA sample adding and microplate processing had long usage time,and the differences between the usage time of the equipment for ELISA sample adding from the laboratories with different sizes were statistically significant(P＜0.05).Conclusion The equipment configuration of blood testing laboratories of blood stations in Shandong Province varies greatly,and each laboratory has to take measures based on their own actual situations,such as increasing the number of equipment,purchasing domestic equipment or accelerating equipment updating.[Chinese Medical Equipment Journal,2024,45(3):81-85]

OBJECTIVES: To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia. METHODS: A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively. RESULTS: Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia. CONCLUSIONS The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

With the intensive aging of the population, it's imperative and important to train a number of geriatric specialists. Essential clinical knowledge and skills as well as accomplishment of medical humanistic spirit are core competences of an eligible geriatrician. The standardized training of geriatric specialists is facing a few challenges such as incomplete comprehension of the training program and trainees, a lack of enough trainees, and a lack of standardized management for the program. An efficient social support system, a normative educational training system, an effective supervision and evaluation system, first-class teaching staff, and qualified trainees are important guarantees for the standardized training program.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective:To investigate the role of contrast-enhanced ultrasound (CEUS) features in preoperative screening of patients with uterine fibroids treated by magnetic resonance imaging guided focused ultrasound (MRgFUS).Methods:The preoperative CEUS features of 28 patients (32 lesions) with uterine fibroids treated by MRgFUS in Xijing Hospital of Air Force Military Medical University from January 2018 to March 2021 were analyzed. The relationships between the imaging features of lesions and the necrosis range were evaluated, which included echo intensity in gray-scale ultrasound, the patterns of the perfusion intensity, perfusion distribution, the contrast agent into the model, lesions with entangled branch vessels, ring-like enhancement, and perfusion regression.Results:The gray-scale ultrasound showed that 68.75%(22/32) lesions were hypoechoic. The CEUS showed that 81.25%(26/32) lesions were iso/hypo-enhancement, 65.63%(21/32) lesions were heterogeneous enhancement, 68.75%(22/32) lesions with entangled branch vessels, 71.88%(23/32) lesions with ring-like enhancement, and 75%(24/32) lesions with fast-out enhancement. The 6 indicators above-mentioned had effects on the non-perfusion volume ratio≥50%, the differences were statistically significant (all P<0.05). Conclusions:CEUS can evaluate the blood flow characteristics in uterine fibroids, providing important information for preoperative screening of uterine fibroids for MRgFUS ablation.

Objective:To explore the short-term outcomes of dual kidney transplantation and summarize its safety and feasibility.Methods:From September 2018 to September 2019, a total of 7 dual kidney transplantations were performed. And retrospective analysis was performed for baseline profiles, clinical data and postoperative complications.Results:The mean age was (62.7±8.5) years for donors and (43.9±9.3) years for recipients. The Remuzzi score of 6 paired kidneys ranged from 4 to 6 points. During follow-ups, the survival rate of 7 dual kidney transplantation grafts and recipients was 100%. The median follow-up period was 16 months. Renal function of 6 recipients normalized within 1 week and delayed graft function (DGF) occurred in one case. All of them underwent unilateral kidney transplantation with an average operative duration of (5.6±1.4) hours. There was no onset of operative complications. One case of rejection was not confirmed by biopsy. Among three patients of lung infections, there was one case of severe pneumonia. In 3 cases, lateral plasma flow of transplanted kidney exceeded that of medial plasma flow.Conclusions:Dual kidney transplantation in adults is both safe and feasible so as to expand the availability of donated kidney.
