The linear correlation coefficients were 0.9971-0.9999, the limits of quantification of the method were 0.10-6.00 μg/L, and the inter-and intra-day precision were 4.6%-9.8% and 1.5%-8.6%, with the recoveries of the spiked standards ranged from 90.0% to 106.1%.Conclusion:The LC-MS/MS method for the determination of metabolites of six psychotropic drugs in human plasma is simple, rapid and sensitive, and can be used for the qualitative and quantitative determination of metabolites in plasma samples of patients suspected of psychotropic drug poisoning.

Objective:To establish a high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the fast determination of maduramicin ammonium (MAD) in rat serum.Methods:In February 2024, rat serum samples were selected and directly injected after extraction and purification with methanol: acetonitrile (1: 1), separated on a C18 chromatographic column, and gradient-eluted using 0.1% formic acid aqueous solution -0.1% formic acid methanol solution as the mobile phase. Under optimized instrument conditions, electrospray positive ion multiple reaction monitoring (MRM) mode was employed for quantification using the external standard method, followed by methodological validation of the established approach.Results:The linearity of MAD in serum was good in the concentration range of 0.5-100 μg/L, and the correlation coefficient was 0.9997. The mean recoveries of MAD from spiked samples were 86.0%-109.6%, with the relative standard deviations were less than 10%. The limit of detection was 0.23 μg/L, The limit of detection was 0.75 μg/L.Conclusion:This method is high sensitive and reliable, which is suitable for the determination of MAD in in mouse serum.

Diamond-Blackfan anemia(DBA),also known as congenital pure red cell aplasia,is a rare genetic disorder characterized by bone marrow failure,congenital anomalies,and severe red blood cell abnormalities.The rarity of the condition,and consequently limited patient pool and scarcity of research models,means that the pathogenic mechanisms associated with genetic mutations in DBA remain uncertain,and the clinical treatment options are limited.This review synthesizes the findings from zebrafish,mouse,and human cellular models of DBA mutations.We clarify the pathogenic mechanisms and monitor the progression of drugs into clinical trials,thereby aiding further in-depth explorations into the etiology and therapeutic advancements for DBA.

Objective:To explore the influencing factors of residual thyroid clearance with 131I after surgery in patients with differentiated thyroid cancer (DTC). Methods:A retrospective analysis was conducted on the clinical data of 100 DTC patients admitted to the Hunan Provincial People′s Hospital from January 2018 to February 2021 who underwent 131I treatment for the first time. The success rates of first thyroidectomy using different doses of 131I, different pathological types, and different treatment times were compared, and logistic regression analysis was conducted to investigate the influencing factors of the efficacy of first postoperative 131I thyroidectomy in DTC patients. Results:A total of 54 patients successfully cleared residual thyroid, 46 patients failed to clear residual thyroid, and the success rate of clearing residual thyroid was 54%. The success rates of first clearance of residual thyroid in patients with 131I doses of 80 mCi, 90 mCi, and 100 mCi were 37.50%(12/32), 52.78%(19/36), and 71.88%(23/32), respectively, with statistically significant differences among the groups ( P<0.05); The success rates of first removal of residual thyroid in patients with follicular carcinoma, mixed papillary follicular carcinoma, and papillary carcinoma were 65.71%(23/35), 39.13%(9/23), and 52.38%(22/42), respectively. There was no statistically significant difference between the groups ( P>0.05); The success rates of first removal of residual thyroid in the group1 of patients (treatment time<3 months), the group2 of patients (treatment time 3-12 months), and the group3 of patients (treatment time>12 months) were 68.09%(32/47), 44.44%(16/36), and 35.30%(6/17), respectively. There was no statistically significant difference between the groups ( P>0.05); There was no statistically significant difference in the success rate of clearing residual thyroid in DTC patients of different genders, ages, pathological stages, and thyroid stimulating hormone (TSH) levels (all P>0.05); The difference in the success rate of clearing residual thyroid in DTC patients with different metastatic conditions and stimulating thyroid globulin (sTg) was statistically significant (all P<0.05); sTg, postoperative lymph node metastasis, and postoperative distant metastasis were independent risk factors for the efficacy of residual thyroid clearance in DTC patients for the first time after surgery (all P<0.05). Conclusions:The influencing factors for the efficacy of the first 131I in removing residual thyroid include differences in 131I dosage, presence or absence of metastatic lesions during treatment, Tg levels, etc. Reducing Tg levels is an important factor in improving remission rate, and controlling lymph nodes and distant metastasis is a key factor for the successful efficacy of the first 131I in removing residual thyroid.

Objective:To analyze the injury factors and prognosis of children with traumatic brain injury (TBI), and to explore the risk factors affecting its severity, so as to provide evidence for the prevention and intervention of TBI in children.Methods:A total of 6 040 children with TBI who were admitted to the Department of Neurosurgery of Children's Hospital of Soochow University from January 1, 2011 to December 31, 2020 were selected. The injury factors and prognosis were retrospectively analyzed. Univariate and multivariate Logistic regression analysis was used to analyze the factors affecting the severity of TBI in children.Results:Of the 6 040 children, 3 681 were males and 2 359 were females. The patients aged 1 to 3 years accounted for the highest proportion (34.0%, 2 056/6 040), and most of them were mild injuries (93.2%, 5 631/6 040). The main injury sites of children with TBI were road (35.9%, 2 167/6 040) and home (31.1%, 1 881/6 040), and the main causes of injury were falling from height (34.9%, 2 107/6 040) and falling (34.5%, 2 085/6 040). Children aged 1 to 3 years were most likely to be injured at home(41.9%, 861/2 056), mainly due to falling from height, while children aged 4 to 6 years were most likely to be injured on the road(43.8%, 828/1 891), mainly due to falling. Logistic regression analysis showed that children's residence, the presence of multiple injuries and the location of brain injury were independent influencing factors for the severity of TBI in children ( χ2=6.58, 138.15, 4.25, all P <0.05). Conclusions:TBI in children aged 1 to 3 years mainly occurred at home, and in children aged 4 to 6 years mainly occurred on the road. Falling from height and falling are the main causes of TBI in children. The society, schools and families should take targeted prevention education and intervention measures according to different age groups. Children who live in rural areas, have multiple injuries, and have multiple brain injury sites are more severely injured. In the process of treating children with TBI, the severity can be quickly predicted based on this, and the treatment efficiency of children with TBI can be improved.

Objective:To explore the factors affecting the safety of home environment for device-aided elderly people, so as to provide a basis for improving the safety of the elderly's home environment and promoting aging-adapted reform.Methods:From August 2021 to March 2022, stratified cluster sampling was used to select 326 device-aided elderly people from 8 communities in Urumqi City as the research subject. The survey was conducted using the General Information Questionnaire, Capacity Assessment Standard Table for the Elderly, Home Environment Safety Assessment Scale for the Elderly, and Home Environment Ageing-adapted Reform Cognition and Needs Concise Questionnaire for the Elderly. Multiple linear regression was used to explore the influencing factors of home environment safety for device-aided elderly people.Results:A total of 326 questionnaires were distributed, and 305 valid questionnaires were collected, with an effective recovery rate of 93.56% (305/326) . The influencing factors of home environment safety for device-aided elderly people included housing area, self-evaluation of the home environment, chronic diseases, monthly pension income, and cognition of aging-adapted reform ( P<0.05) . Conclusions:The aging-adapted reform of home environment should focus on elderly people who suffer from chronic diseases, have poor self-evaluation of the environment, have low monthly pension income and cognition of aging-adapted reform. Relevant departments should promote the self-evaluation methods of home environment and knowledge on home aging-adapted reform.
