Objective To investigate the relationship between the development of terminal rectal ganglion and spinal cord/sacral abnormalities in boys with complex anorectal malformations(ARMs)in order to improve the understanding of rectal ganglion development abnormalities in ARMs patients.Methods A retrospective trial was conducted on the male patients with complex ARMs admitted to our hospital from 2015 to 2021.The terminal rectal specimens were taken from them during anoplasty.According to the findings on development of terminal rectal ganglion after HE staining,the patients were classified into G1 group(ganglion cells observed)and G2 group(no ganglion cells observed).Imaging techniques were used to evaluate whether there were abnormalities in the spinal cord and sacrum,and their correlation with the terminal rectal ganglion development was analyzed.Results A total of 139 patients were enrolled,and their median age at anoplasty was 5.77(4.57,6.97)months.There were no significant differences between the G1(n=80,57.6％)and G2(n=59,42.4％)groups in ARMs pathological type(P=0.706)and age at surgery(P=0.140).Radiological findings showed there were 48 cases(34.5％)of spinal cord anomalies(SCA),25 cases(18.0％)of sacral abnormalities and 18 cases(12.9％)of coccyx abnormalities.No significant differences were observed in the incidences of SCA and sacral abnormalities between the G1 and G2 groups(P＜0.05).Moreover,the differences of fatty filum terminale and syrinx were statistically significant(P＜0.05).In addition,the ratio of sacrum to coccyx between the G1 and G2 groups were 0.72±0.10 vs 0.67±0.12(P＜0.05)of the anteroposterior position and 0.77±0.09 vs 0.72±0.09(P＜0.05)of the lateral position.Multivariate logistic regression analysis showed that sacral abnormalities,fatty filum terminale and syrinx were independent predictors of rectal terminal ganglion absence in male patients with complex ARMs.Conclusion The development of terminal rectal ganglia in male patients with ARMs is closely associated with the abnormalities of spinal cord and sacrum.Sacral abnormalities,fatty filum terminale and syrinx are independent predictors of rectal terminal ganglion absence in male patients with complex ARMs.

Concerned literature on four kinds of andrographolide injections in recent 15 years were searched in CNKI, Wanfang and VIP databases. The adverse drug reaction(ADR) cases of Chuanhuning, Yanhuning, Xiyanping and Lianbizhi injections were classified and analyzed statistically, including a total of 194 articles and 3 479 cases. The ADR clinical characteristics and occurrence regularity of these four andrographolide injections were analyzed and compared from the gender, age, primary disease, emergence time of ADR, clinical manifestation, allergy history, dosage, prognosis and combined medication of the patients. It is useful to provide valuable references for rational use of these andrographolide injections in clinical practice.

Objective: To investigate the differences in clinical characteristics, diagnosis, and treatment of pediatric septic shock in pediatric intensive care unit (PICU) among hospitals of different levels. Methods: This retrospective study enrolled 368 children with septic shock treated in the PICU of Beijing Children's Hospital, Henan Children's Hospital, and Baoding Children's Hospital from January 2018 to December 2021. Their clinical data were collected, including the general information, location of onset (community or hospital-acquired), severity, pathogen positivity, consistence of guideline (the rate of standard attainment at 6 h after resuscitation and the rate of anti-infective drug administration within 1 h after diagnosis), treatment, and in-hospital mortality. The 3 hospitals were national, provincial, and municipal, respectively. Furthermore, the patients were divided into the tumor group and the non-tumor group, and into the in-hospital referral group and the outpatient or emergency admission group. Chi-square test and Mann-Whitney U test were used to analyze the data. Results: The 368 patients aged 32 (11, 98) months, of whom 223 were males and 145 females. There were 215, 107, and 46 patients with septic shock, with males of 141, 51, and 31 cases, from the national, provincial, and municipal hospitals, respectively. The difference in pediatric risk of mortality Ⅲ (PRISM Ⅲ) scores among the national,provincial and municipal group was statistically significant (26(19, 32) vs.19(12, 26) vs. 12(6, 19), Z=60.25,P<0.001). The difference in community acquired septic shock among the national,provincial and municipal group was statistically significant (31.6%(68/215) vs. 84.1%(90/107) vs. 91.3%(42/46), χ²=108.26,P<0.001). There were no significant differences in compliance with guidelines among the 3 groups (P>0.05). The main bacteria detected in the national group were Klebsiella pneumoniae (15.4% (12/78)) and Staphylococcus aureus (15.4% (12/78)); in the provincial group were Staphylococcus aureus (19.0% (12/63)) and Pseudomonas aeruginosa (12.7% (8/63)), and in the municipal group were Streptococcus pneumoniae (40.0% (10/25)) and Enteric bacilli (16.0% (4/25)). The difference in the proportion of virus and the proportion of 3 or more initial antimicrobials used among the national,provincial and municipal group was statistically significant (27.7% (43/155) vs. 14.9% (13/87) vs. 9.1% (3/33), 22.8%(49/215) vs. 11.2%(12/107) vs. 6.5%(3/46), χ²=8.82, 10.99, both P<0.05). There was no difference in the in-hospital mortality among the 3 groups (P>0.05). Regarding the subgroups of tumor and non-tumor, the national group had higher PRISM Ⅲ (31(24, 38) vs. 22 (21, 28) vs.16 (9, 22), 24 (18, 30) vs. 17(8, 24) vs. 10 (5, 16), Z=30.34, 10.45, both P<0.001), and it was the same for the subgroups of in-hospital referral and out-patient or emergency admission (29 (21, 39) vs. 23 (17, 30) vs. 15 (10, 29), 23 (17, 29) vs. 18 (10, 24) vs. 11 (5, 16), Z=20.33, 14.25, both P<0.001) as compared to the provincial and municipal group. There was no significant difference in the in-hospital mortality among the 2 pairs of subgroups (all P>0.05). Conclusion: There are differences in the severity, location of onset, pathogen composition, and initial antibiotics of pediatric septic shock in children's hospitals of different levels, but no differences in compliance with guidelines and in-hospital survival rate.

Ferroptosis, a programmed cell death modality discovered and defined in the last decade, is primarily induced by iron-dependent lipid peroxidation. At present, it has been found that ferroptosis is involved in various physiological functions such as immune regulation, growth and development, aging, and tumor suppression. Especially its role in tumor biology has attracted extensive attention and research. Breast cancer is one of the most common female tumors, characterized by high heterogeneity and complex genetic background. Triple negative breast cancer (TNBC) is a special type of breast cancer, which lacks conventional breast cancer treatment targets and is prone to drug resistance to existing chemotherapy drugs and has a low cure rate after progression and metastasis. There is an urgent need to find new targets or develop new drugs. With the increase of studies on promoting ferroptosis in breast cancer, it has gradually attracted attention as a treatment strategy for breast cancer. Some studies have found that certain compounds and natural products can act on TNBC, promote their ferroptosis, inhibit cancer cells proliferation, enhance sensitivity to radiotherapy, and improve resistance to chemotherapy drugs. To promote the study of ferroptosis in TNBC, this article summarized and reviewed the compounds and natural products that induce ferroptosis in TNBC and their mechanisms of action. We started with the exploration of the pathways of ferroptosis, with particular attention to the System X_c^--cystine-GPX4 pathway and iron metabolism. Then, a series of compounds, including sulfasalazine (SAS), metformin, and statins, were described in terms of how they interact with cells to deplete glutathione (GSH), thereby inhibiting the activity of glutathione peroxidase 4 (GPX4) and preventing the production of lipid peroxidases. The disruption of the cellular defense against oxidative stress ultimately results in the death of TNBC cells. We have also our focus to the realm of natural products, exploring the therapeutic potential of traditional Chinese medicine extracts for TNBC. These herbal extracts exhibit multi-target effects and good safety, and have shown promising capabilities in inducing ferroptosis in TNBC cells. We believe that further exploration and characterization of these natural compounds could lead to the development of a new generation of cancer therapeutics. In addition to traditional chemotherapy, we discussed the role of drug delivery systems in enhancing the efficacy and reducing the toxicity of ferroptosis inducers. Nanoparticles such as exosomes and metal-organic frameworks (MOFs) can improve the solubility and bioavailability of these compounds, thereby expanding their therapeutic potential while minimizing systemic side effects. Although preclinical data on ferroptosis inducers are relatively robust, their translation into clinical practice remains in its early stages. We also emphasize the urgent need for more in-depth and comprehensive research to understand the complex mechanisms of ferroptosis in TNBC. This is crucial for the rational design and development of clinical trials, as well as for leveraging ferroptosis to improve patient outcomes. Hoping the above summarize and review could provide references for the research and development of lead compounds for the treatment for TNBC.
