Objective:To investigate the diagnostic value of non-high-density lipoprotein cholesterol (non-HDL-C),ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL-C), and triglyceride glucose index (TyG) on metabolic syndrome (MS) in adult women.Methods:This was a cross-sectional study. A total of 24 410 adult women who received health examination in health management center of the Affiliated Hospital of Southwest Medical University were selected from January 2019 to December 2021 as subjects. The subjects′ basic information, physical examination results, and laboratory examination data were collected retrospectively. The relationship between non-HDL-C, TG/HDL-C, TyG, and MS in adult women were examined using multivariate logistic regression analysis. The receiver operating characteristic (ROC) curves were constructed and the area under the curve (AUC) were calculated to evaluate the diagnostic value of each indicator for MS in adult women.Results:Among 24 410 adult females, 800 (3.3%) were found to have MS. After adjusting for age, body mass index, waist circumference, hip circumference, systolic blood pressure, diastolic blood pressure, blood uric acid, history of hypertension, history of diabetes, fatty liver, non HDL-C ( OR=1.608), TG/HDL-C ( OR=1.311), TyG ( OR=13.288) were all risk factors for MS in adult women. non-HDL-C, TG/HDL-C, and TyG, as well as their combined AUC of ROC, were 0.795 (95% CI: 0.742-0.776), 0.909 (95% CI: 0.902-0.917), 0.942 (95% CI: 0.937-0.948), and 0.944 (95% CI: 0.937-0.950), respectively. TyG had the highest diagnostic value for MS in adult women among the three indicators, the optimal cutoff value for TyG was 8.237, with a sensitivity of 93.5% and a specificity of 85.5%. Conclusion:non-HDL-C, TG/HDL-C, TyG, as well as their combination, all demonstrate good diagnostic value for MS in adult women.

Primary liver cancer(PLC)is a common malignant tumor in China.It ranks second in the cause of tumor mortality and it is a serious threat to the lives and health of people.Transcatheter arterial chemoembolization(TACE)is the preferred treatment for patients with HCC who cannot be surgically cured,which is of great significance for prolonging the patient's life.However,the incidence of nausea and vomiting after TACE is very high,which is an important reason for the decline of patient treatment compliance,which seriously affects the quality of life and the effect of interventional therapy.This paper reviews the domestic and abroad literature concerning the nausea and vomiting in patients after TACE,focusing on the clinical features of nausea and vomiting,the risk factors and the assessment tools,so as to provide a scientific basis for clinical early identification and effective intervention of nausea and vomiting after TACE.(J Intervent Radiol,2024,33:565-570)

OBJECTIVE: To explore the clinical effect of Kirschner wire intramedullary fixation in the treatment of both-bone forearm fractures in children of high altitude area. METHODS: From August 2020 to December 2021, 19 children were treated with Kirschner wire intramedullary fixation including 11 males and 8 females, aged from 4 to 13 years old with an average of (8.16±2.71) years old. The course of disease was 1 to 10 days, with a mean of (4.11±2.51) d. First, close reduction was performed. If the reduction was unsuccessful, limited open reduction was performed, followed by Kirschner wire intramedullary fixation of the radius and ulna. The fracture healing was evaluated by X-ray after operation, and the curative effect was evaluated by Anderson forearm function score standard. RESULTS: The wound healed well after operation, 2 cases had clinical manifestations of needle tail irritation after operation, and the symptoms disappeared after removing the internal fixation. The average follow-up time was(7.68±3.50) months (3 to 14 months). X-ray showed that all fracture healing in follow-up, Anderson forearm function score showed excellent in 16 cases, good in 2 cases and fair in 1 case at the final follow-up. CONCLUSION Children with fractures in plateau areas often have delayed medical treatment, lack of medical conditions and insufficient compliance. Based on these characteristics, Kirschner wire intramedullary fixation for the treatment of children's double forearm fractures has the advantages of small injury and rapid recovery. It is a kind of operation method that can be popularized.

Among them, 6 patients were evaluated as partial remission, and underwent successful tumor resection, tumors in 7 patients were stable, and 21 patients suffered from disease progression.Conclusion:After comprehensive therapy, unresectable tumors in some patients could reduce and be rendered resection.

The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

ObjectiveGut microbiota plays an important role in Parkinson′s disease, but the mechanisms behind this remain unknown. This study aims to investigate the characteristics of intestinal microbiota in patients with Parkinson′s disease, and to study the changes of intestinal Prevotella_copri and their role in this disease.Methods The study was carried out in 46 patients with Parkinson′s disease and their spouses. The spouse has been living with the patient for a long time, not suffering from any disease. Fecal samples from all subjects were collected using sterile containers. The bacterial DNA was extracted on ice following the Kit protocol. We used the BGISEQ-500 high-throughput sequencing platform to conduct metagenomic shotgun sequencing, to explore the changes of patients′ intestinal microbiota through bioinformatics, and to analyze the function and role of differential microorganisms in disease.ResultsCompared to healthy spouse, the gut microbiota of patients with Parkinson′s disease was significantly changed, which was characterized by decreased Prevotellaceae and Prevotella_copri, but by significantly elevated Bacteroides_stercoris and Escherichia_coli. Prevotella_copri was decreased with age increasing. The correlation analysis showed a significantly negative correlation between the abundance of Prevotella_copri and age, H-Ystage, UPDR total score, and UPDRS Ⅲ score. Results of the random forest model indicated five items including Prevotella_copri had good predictive value for the disease. The functional analysis stated pathways associated with super-pathway of thiamin diphosphate biosynthesis, 4-aminobutanoate degradation. The glucose-1-phosphate degradation and methyl phosphonate degradation significantly increased in patients, while pathways associated with aromatic amino acid biosynthesis, chorismate biosynthesis, thiamin formation, and pyrimidine deoxyribonucleosides salvage significantly decreased. Pathways of Prevotella_copri were mainly concentrated in UMP biosynthesis, S-adenosyl-L-methionine cycle, and guanosine ribonucleotides de novo biosynthesis.ConclusionStructural composition and metabolic functions of gut microbiota were significantly changed in patients with Parkinson′s disease. Prevotella_copri plays an important role in the occurrence and progression of the disease and can be used as a potential biomarker for Parkinson′s disease.
