Objective To investigate the role of Kelch-like-epichlorohydrin-associated protein 1/nuclear factor erythroid-derived factor-2-related factor 2(Keap1-Nrf2)and nuclear factor-κB(NF-κB)signaling pathways in sepsis-associated encephalopathy(SAE).Methods Male C57BL/6J mice of SPF were randomly divided into four groups(n=10):the control group and LPS 6 h,24 h and 48 h groups.The behavioral changes of the mice were assessed based on their general conditions and open field test(OFT).ELISA was used to measure the levels of pro-inflammatory cytokines in mouse serum,and the antioxidant capacity assay kit to examine antioxidant activity in brain tissues of mice.Real-time quantitative PCR(qPCR)was adopted to detect the mRNA levels of toll-like receptor4(Tlr4),NF-κB,Keap1 and Nrf2 in the hippocampus,and to determine protein expressions of NF-κB a Nrf2、Keap1 and Tlr4 with Western blotting.Results Compared to the control group,the serum concentrations of interleukin 6(IL-6)in lipopolysaccharide(LPS)groups increased at 6 h,and reached the peak at 24 h and 48 h(P＜0.01).The levels of serum interleukin 18(IL-18)in the LPS groups increased significantly at 6 h and 24 h(P＜0.01)but there was no statistically significant difference compared with the 48h group.The results indicated the activity of superoxide dismutase(SOD)and glutathione(GSH)in brain tissues in LPS groups increased(P＜0.01).OFT results showed the time spent in the center of the open field,the distance covered around the center,and total distance covered by mice in LPS groups were significantly reduced(P＜0.01),except for the time spent in the center of the open field in the LPS 24 h group.The mRNA expressions of Tlr4 and(LPS 6 h,48 h)NF-κB in the hippocampus tissue of mice in LPS groups were elevated(P＜0.05),so were the mRNA expressions of Keap1 and Nrf2 in LPS 6 h group.Additionally,the protein expressions of NF-κB,Keap1 and Tlr4 increased in LPS groups,so did the protein expression of Nrf2 in LPS 24 h and 48 h groups(P＜0.05).Conclusion Keap1-Nrf2 and NF-κB signaling pathways may play a certain role in SAE.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

Traditional Chinese medicine,ancient Greek medicine,Ayurvedic medicine,and Arab medicine are recognized as the four major traditional medicines in the world.It reviews the education and training systems of the four major traditional medicines and finds that traditional Chinese medicine focuses on the teacher-student relation-ship and the combination of theory and practice;Ancient Greek medicine was mainly characterized by strong theoreti-cal research and experimental observation;Ayurveda highly values cultural identity as its main characteristic;Arab medicine attaches great importance to cultural exchange and practical promotion.It suggests promoting innovative de-velopment,strengthening practical teaching,improving teaching quality,strengthening international exchanges and cooperation,and increasing public acceptance abroad.
