Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

OBJECTIVE: To investigate the clinical efficacy and safety of single Kirschner wire assisted poking and closed reduction in the treatment of Gartland type Ⅲ supracondylar humeral fractures in children. METHODS: A retrospective analysis was performed on patients diagnosed with Gravland type Ⅲ supracondylar humeral fractures between January 2022 and June 2023. A total of 46 patients were treated with closed reduction assisted by Kirschner wires and percutaneous Kirschner wire internal fixation.There were 25 males and 21 females. The age ranged from 5 to 10 years old, with an average of (5.8±1.8) years old. The left side was involved in 28 patients and the right side in 18 patients. Record the operative duration for patients, the number of fluoroscopic exposures, fracture healing time, postoperative carrying angle, Baumann angle, elbow joint function score at three months post-operation, and any associated complications. RESULTS: All 46 patients were followed up for a period of 12 to 16 weeks, with an average of (13.74±1.44 )weeks. The operation duration was (30.7±5.1) minutes, the fluoroscopy count was (10.2±2.7) times, the postoperative carrying angle of the elbow joint was (8.7±2.2) degrees, and the Baumann angle was (71.5±2.9) degrees. All fractures achieved successful union in all patients, with a mean healing time of (25.5±1.7) days.At the final follow-up, elbow joint function was assessed using the Flynn criteria, with 43 patients rated as excellent and 3 patients rated as good. No complications were observed, including cubitus varus, nerve injury, or local infection. CONCLUSION The use of a single Kirschner wire assisted prying reduction for treating Gartland type Ⅲ supracondylar humeral fractures in children demonstrates excellent clinical efficacy and safety.

Mycophenolic acid (MPA), the active moiety of both mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS), serves as a primary immunosuppressant for maintaining solid organ transplants. Therapeutic drug monitoring (TDM) enhances treatment outcomes through tailored approaches. This study aimed to develop an evidence-based guideline for MPA TDM, facilitating its rational application in clinical settings. The guideline plan was drawn from the Institute of Medicine and World Health Organization (WHO) guidelines. Using the Delphi method, clinical questions and outcome indicators were generated. Systematic reviews, Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence quality evaluations, expert opinions, and patient values guided evidence-based suggestions for the guideline. External reviews further refined the recommendations. The guideline for the TDM of MPA (IPGRP-2020CN099) consists of four sections and 16 recommendations encompassing target populations, monitoring strategies, dosage regimens, and influencing factors. High-risk populations, timing of TDM, area under the curve (AUC) versus trough concentration (C₀), target concentration ranges, monitoring frequency, and analytical methods are addressed. Formulation-specific recommendations, initial dosage regimens, populations with unique considerations, pharmacokinetic-informed dosing, body weight factors, pharmacogenetics, and drug‍-‍drug interactions are covered. The evidence-based guideline offers a comprehensive recommendation for solid organ transplant recipients undergoing MPA therapy, promoting standardization of MPA TDM, and enhancing treatment efficacy and safety.

To establish the amplification-refractory mutation system quantitative real-time PCR (ARMS-qPCR) method based on qPCR technique for detecting the c.2T>C mutation of SLC25A13 gene and validate its diagnostic performance. According to the principle of ARMS-qPCR primer design, the specific primers were designed for the conserved sequence of SLC25A13. The c.2T>C mutation ARMS-qPCR detection assay of SLC25A13 gene and the corresponding Sanger sequencing system were established through the use of the synthetic plasmids of homozygous mutation and 200 human peripheral blood specimens which were verified by Sanger sequencing as templates, and the diagnostic efficacy of the qPCR assay was validated by using nucleic acid extracted from another 200 human peripheral blood specimens and the results obtained were compared with the Sanger sequencing results as the gold standard, and the consistency of the two detection methods was analyzed. The results showed that the qPCR assay could accurately identify artificial plasmids carrying different mutations of SLC25A13 gene, and distinguish between wild type SLC25A13 gene and the c.2T>C mutation. This method was used to detect the mutation status of SLC25A13 c.2T>C in human peripheral blood, and the detection results were 100% consistent with the Sanger sequencing results. Among the 200 blood samples, 8 samples (4%) carried the c.2T>C mutation of SLC25A13 gene and 192 samples (96%) did not carry it. In conclusion, the ARMS-qPCR test established in this study can quickly, simply and accurately detect the c.2T>C mutation of SLC25A13 gene, which is helpful for the diagnosis of citrin deficiency (CD).

Objective To investigate the environmental contamination related to first patient with carbapenem-re-sistant Acinetobacter baumannii(CRAB)infection and the infection status of relevant patients in a newly established intensive care unit(ICU)of a hospital in Tibetan area,and analyze the transmission risk.Methods From the ad-mission in ICU of a patients who was first detected CRAB on November 15,2021 to the 60th day of hospitalization,all patients who stayed in ICU for＞48 hours were performed active screening on CRAB.On the 30th day and 60th day of the admission to the ICU of the first CRAB-infected patient,environment specimens were taken respectively 2 hours after high-frequency diagnostic and therapeutic activities but before disinfection,and after disinfection but before medical activities.CRAB was cultured with chromogenic culture medium.Results Among the 13 patients who were actively screened,1 case was CRAB positive,he was transferred from the ICU of a tertiary hospital to the ICU of this hospital on November 19th.On the 40th day of admission to the ICU,he had fever,increased frequency for sputum suction,and CRAB was detected.The drug sensitivity spectrum was similar to that of the first case,and he also stayed in the adjacent bed of the first case.64 environmental specimens were taken,and 9 were positive for CRAB,with a positive rate of 14.06％,8 sampling points such as the washbasin,door handle and bed rail were positive for CRAB after high-frequency diagnostic and therapeutic activities.After routine disinfection,CRAB was detected from the sink of the washbasin.Conclusion For the prevention and control of CRAB in the basic-level ICU in ethnic areas,it is feasible to conduct risk assessment on admitted patients and adopt bundled prevention and con-trol measures for high-risk patients upon admission.Attention should be paid to the contaminated areas(such as washbasin,door handle,and bed rail)as well as the effectiveness of disinfection of sink of washbasin.

BACKGROUND:Stem cell transplantation is a new way to prevent and cure intervertebral disc degeneration.However,whether the transplanted stem cells can survive,proliferate,differentiate,and restore the function of nucleus pulposus cells after transplantation,is the key and difficult point to overcome. OBJECTIVE:To explore the effects of Bushenhuoxue decoction on survival,proliferation,and nucleus pulposus-like differentiation of adipose-derived stem cells. METHODS:A Transwell chamber was used to construct a co-culture model of human adipose-derived stem cells and human degenerative nucleus pulposus cells.The experiment was divided into control group,model group,drug-containing serum group,and drug-free serum group.Except for the control group,the co-culture system of other groups was treated with 50 μmol/L tert-butyl hydrogen peroxide for 24 hours.The drug-containing serum group and drug-free serum group were treated with DMEM low-glucose complete culture medium containing drug-containing serum of Bushenhuoxue decoction or drug-free serum with 20％volume fraction for 48 hours.The sublayer adipose-derived stem cells were taken.Toluidine blue staining was used to detect proteoglycan synthesis levels.Real-time PCR method was used to detect mRNA expression of type Ⅱ collagen,proteoglycan and SRY-box transcription factor 9.The protein expression of SOX9 was detected by western blot assay.Lactate dehydrogenase assay was used to detect cytotoxicity.Flow cytometry was used to detect reactive oxygen species,and β-galactosidase staining was used to detect cell senescence. RESULTS AND CONCLUSION:(1)Compared with the control group,the proportion of necrotic cells in the model group increased;toluidine blue staining became lighter,and the expression levels of type Ⅱ collagen,proteoglycan,SOX9 mRNA and SOX9 protein decreased(P<0.05).Compared with the model group,the drug-containing serum of Bushenhuoxue decoction could significantly reduce cell injury and promote the expression of type Ⅱ collagen,proteoglycan,SOX9 mRNA,and SOX9 protein(P<0.05),but the improvement in the drug-free serum group was not significant(P>0.05).(2)Compared with the control group,the contents of cytotoxicity,reactive oxygen species,and cell senescence in the model group were significantly increased.Compared with the model group,the microenvironment of the coculture system was significantly improved by drug-containing serum of Bushenhuoxue decoction(P<0.05),while drug-free serum had no significant effect on the microenvironment of the co-culture system(P>0.05).(3)The results show that Bushenhuoxue decoction can promote the survival,proliferation,and nucleus pulposus-like differentiation of adipose-derived stem cells.
