OBJECTIVETo study the toxicity changes of different proportions of Radix Adenophora, Radix Glehniae combined with Veratrum nigrum L., thus providing acute toxicity data and investigating whether decoction factors were correlated with toxicity.
METHODSThe uniform design method was used by two factors and seven levels to investigate the toxicity changes in different proportions of Radix Adenophora, Radix Glehniae combined with Veratrum nigrum L. The decoction factors were also investigated.
RESULTSThe compatibility toxicity was affected mainly by Veratrum nigrum L. and the toxicity increased along with increased doses of Veratrum nigrum L. The toxicity of co-decoction was higher than mixed decoction in the same dosage of Radix Glehniae and Veratrum nigrum L. The promotion of the dissolution of the toxic component of Veratrum nigrum L. in co-decoction may be the cause of the higher toxicity.
CONCLUSIONRadix Adenophora and Radix Glehniae combined with Veratrum nigrum L. resulted in higher toxicity, which indicated that the incompatibility between Radix Adenophora, Radix Glehniae, and Veratrum nigrum L. In clinic practice, a prescription contained these drugs should be avoided.

Objective To evaluate the uncertainty in the determination of lamotrigine (LTG) in human serum with high performance liquid chromatography (HPLC).Methods It was analyzed that the influences of various factors for detection results,including weighing,solution preparation,serum extraction,calibration curve fitting repeatability and so on.The expanded uncertainty was evaluated and combined by each component of uncertainty.Results The expanded uncertainty of lamotrigine at low (1.50 μg · mL-1),middle (8.00 μg · mL-1),high (20.00 μg · mL-1) concentrations were UL =0.30,UM =0.53,UH =0.98,respectively (P =95%,k =2).The corresponding test concentration were (1.51 ±0.30),(8.22±0.53),(20.40±0.98) μg · mL-1,respectively.Conclusion The relative uncertainty on the determination of lamotrigine in human serum by HPLC was mainly caused by repeatability,calibration curve fitting and extraction recovery;repeatability and calibration curve fitting were the important factor in influencing the results of low concentrations.

Objective To investigate the nutritional status of children with Crohn's Disease (CD) at diagnosis and its association with clinical characteristics. Methods A retrospective analysis was performed for the clinical data and nutritional status of 118 children with CD who were admitted to Beijing Children's Hospital,Capital Medical University,from January 2016 to January 2024. A multivariate logistic regression analysis was used to investigate the risk factors for malnutrition. Results A total of 118 children with CD were included,among whom there were 68 boys (57.6%) and 50 girls (42.4%),with a mean age of (11±4) years. Clinical symptoms mainly included recurrent abdominal pain (73.7%,87/118),diarrhea (37.3%,44/118),and hematochezia (32.2%,38/118),and 63.6% (75/118) of the children had weight loss at diagnosis. The incidence rate of malnutrition was 63.6% (75/118),and the children with moderate or severe malnutrition accounted for 67% (50/75). There were 50 children (42.4%) with emaciation,8 (6.8%) with growth retardation,and 9 (7.6%) with overweight or obesity. Measurement of nutritional indices showed a reduction in serum albumin in 83 children (70.3%),anemia in 74 children (62.7%),and a reduction in 25 hydroxyvitamin D in 15 children (60%,15/25). The children with malnutrition had significantly higher disease activity,proportion of children with intestinal stenosis,and erythrocyte sedimentation rate and a significant reduction in serum albumin (P<0.05). The multivariate logistic regression analysis showed that intestinal stenosis was an independent risk factor for malnutrition in children with CD (OR=4.416,P<0.05). Conclusions There is a high incidence rate of malnutrition in children with CD at diagnosis,which is associated with disease activity and disease behavior. The nutritional status of children with CD should be closely monitored.

Background:
Decision-making concerning the treatment of choroid plexus tumor (CPT) in pediatric patients remains a topic of considerable debate. The aim of this work was to describe clinical features and prognostic risk factors of CPT in the pediatric population and to provide theoretical opinions regarding clinical decisions for CPT.
Methods:
The data of 96 patients with CPT and younger than 14 years were retrospectively analyzed. Clinical characteristics such as pathological type of CPTs, rate and severity of hydrocephalus, treatment and outcome, and recurrence were investigated. For categorical variables, the Pearson's Chi-square test was performed. The Mann-Whitney U-test was used for comparisons between nonnormally distributed parameters. Log-rank test was used for progression-free survival (PFS).
Results:
The study included 70 choroid plexus papilloma (CPP) cases, 17 atypical choroid plexus papilloma (aCPP) cases, and 9 choroid plexus carcinoma (CPC) cases. Compared with patients with CPP or aCPP, patients with CPC had a shorter disease course (median: CPP, 4 months; aCPP, 2 months; CPC, 1 month; H: 23.5, P < 0.001), higher rate of acute hydrocephalus (CPP, 27.1%; aCPP, 52.9%; CPC, 77.8%; χ = 10.9, P < 0.05), and lower incidence of cure rate (CPP, 85.7%; aCPP, 70.5%; CPC, 33.3%; χ = 13.5, P < 0.05). The severity of hydrocephalus with tumor in the lateral or third ventricle was significantly higher than that with tumors in the fourth ventricle (severe hydrocephalus: lateral ventricle, 51.7%; third ventricle, 47.0%; fourth ventricle, 11.1%; χ = 26.0, P < 0.001). Patients with gross total surgical resection had no better PFS than those with partial resection because of the use of adjuvant therapy in the latter (χ = 4.0, P > 0.05). Patients with CPC experienced shorter time for recurrence than those with CPP or aCPP (χ = 40.1, P < 0.0001).
Conclusions
Our results indicated that CPP in the fourth ventricle could trigger serious clinical symptoms at an early stage, requiring early intervention. Adjuvant treatment might be necessary for patients with partially resected CPP, aCPP, and CPC to achieve a favorable outcome.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
