Objective:To investigate effect of hyperbaric oxygen chamber therapy at postoperative early period and its impact on the prognosis of patients with traumatic intracranial hematoma.Methods:A total of 86 patients with traumatic intracranial hematoma who admitted to the First Affiliated Hospital of Xinjiang Medical University from January 2022 to January 2024 were retrospectively selected,and they were divided into observation group and control group according to random number table,with 43 cases in each group.All patients underwent surgery for treatment,and control group received conventional medicine treatment after surgery,while observation group received hyperbaric oxygen chamber therapy at postoperative early period on the basis of conventional medicine treatment after surgery.The clinically curative effect,cerebral hemodynamics,markers of brain injury,prognostic quality scores,and treatment safety of the two groups were assessed.Results:The total effective rate of the observation group was 93.02%,which was higher than that of the control group(x2=5.460,P<0.05).After treatment,the blood flow velocity(Vd),blood flow volume(BF)and pulsatility index(PI)of cranial arteries of the observation group were higher than those of the control group,and the resistance index(RI)of the observation group was lower than that of the control group(t=5.419,3.459,2.905,4.182,P<0.05).The levels of glial fibrillary acidic protein(GFAP),central nervous system specific protein(S100β)and neuron-specific enolase(NSE)of the observation group were lower than those of the control group after treatment(t=3.865,4.315,5.177,P<0.05).In addition,the scores of national institute of health stroke scale(NIHSS)and modified Rankin scale(mRS)of the observation group were lower than those of the control group,and the score of the comprehensive assessment questionnaire for quality of life(GQOLI-74)of the observation group were higher than those of the control group(t=4.524,5.323,3.676,P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion:The postoperative early treatment with hyperbaric oxygen chamber for traumatic intracranial hematoma has a favorable effect,which can enhance the cerebral hemodynamics,and reduce the markers'level of brain injury,and improve the prognostic quality of life of patients.Its safety in treatment is favorable.

Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors worldwide. The traditional early screening modality of ultrasound,when combined with the biomarker alpha-fetoprotein (AFP),is deficient in sensitivity and specificity. In recent years,HCC risk assessment models based on statistical methods have been widely developed and validated due to advantages such as good efficacy,non-invasiveness,and ease of generalization. Currently,HCC risk assessment models adapted to the characteristics of patients with chronic liver disease,patients with hepatitis B and C,patients with cirrhosis,and the general population have been developed. The purpose of this review is to assist clinical diagnosis treatment,and scientific research by analyzing the current research status and development of liver cancer risk assessment models.

Objective To assess the accuracy of pN staging prediction in papillary thyroid carcinoma (PTC) using ultrasound radiomics and deep neural networks (DNN). Methods A retrospective analysis was conducted on 375 patients with pathologically confirmed PTC, comprising 261 cases in the training set and 114 in the test set. Staging was categorized as pN0 (no cervical lymph node metastasis), pN1a (central neck lymph node metastasis), and pN1b (lateral neck lymph node metastasis). An ultrasound physician manually segmented the regions of interest (ROIs) for PTC, extracting 1899 radiomic features. Dimensionality reduction was performed using the least absolute shrinkage and selection operator (LASSO) regression. A DNN model for predicting PTC pN staging was developed using the H2O deep learning platform, trained on the training set, and validated on the test set to assess the accuracy of the optimal model. Results A total of 153 patients were in the pN0 stage, 131 patients in the pN1a stage, and 91 patients in the pN1b stage. LASSO regression selected 15 radiomic features for each PTC. The optimal DNN model, constructed using these 15 features, achieved accuracies of 85.82% on the training set and 81.57% on the test set. Conclusion Ultrasound radiomics of PTC demonstrates high accuracy in predicting pN staging and shows potential for automating N staging in patients.

Objective:To describe the distribution characteristics of alcohol consumption in adult twins in the Chinese National Twin Registry (CNTR), and further explore the influence of genetic factors on alcohol consumption in adult twins.Methods:The subjects of the study were twins registered by CNTR in 11 project areas across China from 2010 to 2018. A total of 56 966 twins (28 483 pairs) aged 18 years and above who answered questions about drinking behavior were included, and the random effect model was used to describe the population and regional distribution characteristics of alcohol consumption. Intra-pair analysis was performed to calculate the concordance rate and heritability of their alcohol consumption.Results:The age of all subjects was (36.6±12.0) years, and current drinkers accounted for 16.6% (9 461/56 966) of all subjects. In men, those aged 50-59 years, those in northern China, those living in rural area, those with low education level and those with high BMI, the proportions of current drinkers were higher. After excluding 468 pairs of twins who had stopped alcohol use and 21 764 pairs of twins who had no drink or had small amount drink, an intra-pair analysis was conducted in 4 929 pairs of same-sex twins, and found that the concordance rate of alcohol consumption was 64.0% (2 059/3 215) in monozygotic twins, and 52.6% (902/1 714) in dizygotic twins, the difference was significant ( P<0.001), and the heritability of alcohol consumption was 24.1% (95% CI: 18.9%- 29.3%). The further stratified analysis found that in southern men, the heritability was highest in those aged 40-49 years (36.1%, 95% CI: 21.6%-50.7%), while in northern men, the heritability was highest in those aged 50-59 years (34.2%, 95% CI: 18.1%-50.3%). Conclusions:In adult twins in China, there were population and regional differences in the distribution of alcohol consumption behavior, and alcohol consumption was influenced by genetic factors, and gender, age and region had potential modifying effects.
