Depression is increasingly prevalent among adolescents and can profoundly impact their lives. However, the early detection of depression is often hindered by the time-consuming diagnostic process and the absence of objective biomarkers. In this study, we propose a novel approach for depression detection based on an affective brain-computer interface (aBCI) and the resting-state electroencephalogram (EEG). By fusing EEG features associated with both emotional and resting states, our method captures comprehensive depression-related information. The final depression detection model, derived through decision fusion with multiple independent models, further enhances detection efficacy. Our experiments involved 40 adolescents with depression and 40 matched controls. The proposed model achieved an accuracy of 86.54% on cross-validation and 88.20% on the independent test set, demonstrating the efficiency of multimodal fusion. In addition, further analysis revealed distinct brain activity patterns between the two groups across different modalities. These findings hold promise for new directions in depression detection and intervention.

Objective:To determine the clinical factors affecting Central lymph node metastases (CLNM) of single Papillary thyroid carcinoma (PTC). To predict the value of age for CLNM under different genders and the status of Hashimoto’s thyroiditis (HT) .Methods:The clinical data of 4 115 patients with PTMC (≤10.0 mm) and 664 patients with PTC (> 10.0 mm) in Hangzhou First People’s Hospital affiliated to Westlake University Medical School from Jan. 2010 to Aug. 2023 were retrospectively analyzed, and the independent risk factors of PTMC and PTC CLNM were identified by univariate and multivariate logistic regression analysis. According to different gender and HT status, the patients were divided into male group, female group, HT group and non-HT group. The optimal age threshold and diagnostic efficacy of CLNM in each subgroup were determined by Receiver operating characteristic area under the curve (AUC) .Results:The proportion of CLNM in 3451 PTMCs and 664 PTCs was 27.2% (937/3451) and 58.9% (391/664) ( χ2=256.565, P<0.050), respectively. Univariate and multivariate regression analysis showed that larger tumor ( OR 1.230), male ( OR 2.085), older age ( OR 0.960) and HT ( OR 0.697) were independent predictors of the occurrence of CLNM in PTMC. Only male ( OR 1.460) and older ( OR 0.963) PTC were independently associated with CLNM. Subgroup analysis showed that the age-predicted AUC of CLNM in male, HT and non-HT patients in PTC were higher than that of PTMC, which were 0.642-0.689 and 0.635-0.659, respectively. The age thresholds of female, HT and non-HT subgroups in PTC were lower than those in PTMC, which were 38.5 to 39.5 years old and 41.5 to 42.5 years old, respectively. Conclusions:Larger tumor, male, older patients and HT can independently predict the risk of CLNM in PTMC, while only male and older people can independently predict the risk of CLNM in PTC. There are certain differences in the age of CLNM occurrence between PTMC and PTC patients with different genders and HT combination status. It is of great significance to correctly understand these differences for providing personalized clinical treatment.

Objective To construct and validate of a nomogram predictive model for high-volume lymph node metastasis(HVM)in multifocal papillary thyroid carcinoma(MPTC).Methods Between January 2010 to January 2024,a total of 1146 and 234 patients with multifocal papillary thyroid carcinoma(MPTC)were diagnosed at Hangzhou First People's Hospital(Center A)and Hangzhou Cancer Hospital(Center B),respectively.Patients from Center A were randomly allocated to training set(n=803)and testing set(n=343)in a 7:3 ratio,while those from Center B(n=234)comprised an external validation set.Independent risk factors for HVM in MPTC patients were identified through univariate and multivariate Logistic regression analysis in training set,leading to the development of a nomogram predictive model.The generalizability of this model was subsequently assessed using both testing set and external validation set.The area under the curve(AUC)of receiver operating characteristic curve,sensitivity,and specificity evaluate the discriminative ability of the model.Results The incidence of HVM was 13.3％at center A and 12.8％at center B.Logistic regression identified male gender(OR=2.91,95％CI:1.835-4.599),maximum lesion diameter(OR=1.05,95％CI:1.021-1.070),and age(OR=0.95,95％CI:0.936-0.972)as independent risk factors for HVM.Anomogram based on these factors showed an AUC of 0.767 with 72.6％sensitivity and 70.2％specificity in training set,and 0.838 with 94.9％sensitivity and 68.4％specificity in testing set,and 0.769 with 63.3％sensitivity and 84.3％specificity in external validation set.The calibration curve demonstrated good agreement with the ideal curve.Conclusion The prediction model constructed based on clinical risk factors can effectively predict the probability of HVM in MPTC patients.

In order to effectively prevent the damage to the human body caused by abnormal oxygen concentration in the medical hyperbaric oxygen chamber, a ZigBee-based medical hyperbaric oxygen chamber oxygen concentration automatic control system is designed. The data acquisition module uses the microprocessor STM32F103C8T6 to receive the oxygen concentration data of each acquisition point, and the ZigBee of the data processing module transmits the processing results to the MSP430G2553 single-chip microcomputer at the receiving end of the slave. The MSP430G2553 single-chip microcomputer uses a self-organizing TS fuzzy neural network (SOTSFNN) and adds activation. The intensity concept realizes automatic control of the oxygen concentration in the hyperbaric oxygen chamber, and controls the buzzer to give an alarm when the oxygen concentration is lower than 19 mg/L and higher than 23 mg/L, and displays the current real-time oxygen concentration through LCD12864. The experimental results show that as the communication distance increases, the packet loss rate of the system is always lower than 5%, and the signal strength under the same communication distance is better; the system can effectively control the oxygen concentration value within the set range, and the oxygen concentration. The control accuracy is high and the stability is good.

OBJECTIVE: To detect potential variants in eight Chinese pedigrees affected with autosomal dominant polycystic kidney disease (ADPKD) and provide prenatal diagnosis for two of them. METHODS: Whole exome sequencing and high-throughput sequencing were carried out to detect variants of PKD1 and PKD2 genes in the probands. Sanger sequencing was used to validate the variants, and their pathogenicity was predicted by searching the ADPKD and protein variation databases. RESULTS: Eight PKD1 variants were detected, which have included five nonsense mutations and three missense mutations. Among these, four nonsense variants (PKD1: c.7555C>T, c.7288C>T, c.4957C>T, c.11423G>A) were known to be pathogenic, whilst one missense variant (PKD1: c.2180T>G) was classified as likely pathogenic. Three novel variants were detected, which included c.6781G>T (p.Glu2261*), c.109T>G (p.Cys37Gly) and c.8495A>G (p.Asn2832Ser). Prenatal testing showed that the fetus of one family has carried the same mutation as the proband, while the fetus of another family did not. CONCLUSION PKD1 variants, including three novel variants, have been identified in the eight pedigrees affected with ADPKD. Based on these results, prenatal diagnosis and genetic counseling have been provided.

Background Magnesium is an important nutrient, and participates in most metabolic processes. Many studies show an association between dietary magnesium intakes and nutrition-related diseases such as diabetes. However, the data of dietary magnesium intakes and secular trends among the whole life cycle of Chinese residents are not available. Objective To investigate the dietary magnesium intakes and associated secular trends over the past three decades in residents of all ages and China, to identify the high-risk residents of magnesium deficiency and plan nutritional interventions, and provide basic data support for the revision of dietary magnesium reference intake. Method The data came from the 10 rounds of the "China Health and Nutrition Survey" from 1991 to 2018, and the participants with complete sociodemographic and dietary data wereselected. The median intakes, insufficient rates, and secular trends of dietary magnesium intakes were analyzed in different survey years. Analysis of multiple linear regression was used to analyze the annual change characteristics of dietary magnesium intakes controlling gender, age, education, urban-rural stratum, and north-south region. Wilcoxon trend test was used to analyze the secular trends of dietary magnesium intakes in different characteristic groups. The trends of insufficient rate were analyzed by Cochran-Armitage trend test among different characteristic groups. Results A total of 127169 residents were included in the present study. The medians of dietary magnesium intakes in 1991, 1993, 1997, 2000, 2004, 2006, 2009, 2011, 2015, and 2018 were 283.70, 283.38, 304.26, 285.50, 283.64, 275.49, 267.92, 242.93, 240.51, and 238.89 mg·d⁻¹, respectively, showing a significant downward trend (F=2931.81, P<0.001). Dietary magnesium intakes showed significant differences in gender, age, education level, income level, urban-rural stratum, and north-south region in almost all survey years, except that there was no significant difference among different income groups in 1991. Insufficient rate of dietary magnesium intake showed a significant upward trend (Z=62.62, P<0.001), approximate 60% of Chinese residents consumed insufficient magnesium. The insufficient rate was 53.94% for male and 65.35% for female, and the insufficient rate in the 14-17 age group was as high as 71.29%. Conclusion The dietary magnesium intake shows a significant downward trend and insufficient intake of dietary magnesium is prevalent among Chinese population. It is necessary to observe the high-risk population and conduct relevant nutritional interventions, as well as to further assess the recommended intake of magnesium.

Objective:To explore the underlying genetic causes of neonatal encephalopathy complicated with perinatal asphyxia.Methods:From the neonates recruited to the Neonatal Genome Project of Children′s Hospital of Fudan University between January 2016 and January 2019, 113 neonates with neonatal encephalopathy and acute peripartum or intrapartum event or Apgar score ≤7 were enrolled in this study. The clinical data, laboratory results, the findings of electroencephalograph and magnetic resonance imaging or head ultrasound, and the genetic information were retrospectively analyzed.Results:Of the 133 neonates with neonatal encephalopathy and acute peripartum or intrapartum event or Apgar score ≤7 scores, 77 (57.9%) were males, 56 (42.1%) were female, 56 (42.1%) were delivered via cesarean section, and 77(57.9%) were born by vaginal delivery. Among these cases, 68 (51.1%) were diagnosed of hypoxic ischemic encephalopathy, 25 (18.8%) had intracranial hemorrhage, 20 (15%) were related to genetic diseases, and 5 (3.8%) had sepsis without central nervous infection. A total of 20 cases with positive results by next-generation sequencing test were identified, including 19 cases with pathogenic variations and 1 case with variation of uncertain significance. These 20 cases included 4 cases with congenital myopathy (2 cases of MTM1 gene pathogenic variants, 1 case of ACTA1 and 1 case of RYR1 gene pathogenic variants), 4 cases with genetic syndrome (2 cases of CHD7 gene pathogenic variants, 1 case of PTN11 gene pathogenic variant, and 1 case of NSDHL gene pathogenic variant), 3 cases with metabolic disorders (1 case of OTC gene pathogenic variant, 1 case of MTHFR gene pathogenic variant, and 1 case of ALDH7A1 gene pathogenic variant), 2 cases with epileptic encephalopathy (1 case of KCNT1 and 1 case of PACS2 gene pathogenic variants), 1 case with congenital central hypoventilation syndrome (PHOX2B gene pathogenic variant) and 6 cases with copy-number pathogenic variations. Among these 20 cases, 8(40.0%) neonates were presented with persistent hypotonia, 7(35.0%) neonates with seizures, and 5(25.0%) neonates with congenital malformation. Genetic counseling and further follow-up were performed or suggested for these 20 cases; 4 neonates were deceased, 10 neonates underwent palliative care, and 6 neonates were improved after supportive care and their further follow-up plan were performed in clinics.Conclusions:Genetic diseases are not rare in neonates with neonatal encephalopathy complicated with perinatal hypoxia event. The common causes in these neonates include congenital myopathy, metabolic disorders, genetic syndrome, and epilepsy encephalopathy.

Objective:The existed economic evaluations of cancer screening in Chinese population are almost all single-cancer focused, evidence on parallel comparison among multiple cancers is lacking. Thus, the aim of this study was, from a priority setting perspective, to compare the cost-effectiveness of six common cancers(colorectal cancer, breast cancer, liver cancer, lung cancer, esophageal cancer and stomach cancer) to facilitate policy making in future scaled-up screening in populations in China.Methods:Partially based on our previous single-cancer systematic reviews (colorectal cancer, breast cancer, liver cancer, and lung cancer), evidence of economic evaluations of cancer screening in populations in mainland China were systematically updated and integrated. The main updates include: 1) Stomach cancer and esophageal cancer were newly added to the current analysis. 2) The literature searching was extended to 8 literature databases, including PubMed, EMbase, The Cochrane Library, Web of Science, CBM, CNKI, Wanfang Data, and VIP. 3) The period of publication year was updated to the recent 10 years: January 1, 2009 to December 31, 2018. 4) The study focused on populations in mainland China. Following the standard processes of literature searching, inclusion and exclusion from previous systematic reviews, the basic characteristics, evaluation indicators and main results of the included studies were extracted. All the costs were discounted to 2017 value using the by-year consumer price index of medical and health care residents in China and presented in the Chinese Yuan (CNY). The ratios of incremental cost-effectiveness ratio (ICER) to China′s per capita GDP in 2017 were calculated (<1 means very cost-effective, 1-3 means cost-effective, >3 means not cost-effective). Given a specific indicator, the median value among all reported screening strategies for each cancer was calculated, based on which priority ranking was then conducted among all cancers when data available.Results:A total of 45 studies were included, 22 for breast cancer, 12 for colorectal cancer, 6 for stomach cancer, 4 for esophageal cancer (all conducted in high-risk areas), 1 for liver cancer and none for lung cancer (was not then considered for next ranking due to limited numbers of studies). When based on the indicator, the median ratio of cost per life-year saved to China′s per capita GDP (reported in 12 studies), the lowest ratio (-0.015) was observed in esophageal cancer among 16 strategies of 2 studies ( N=2, n=16), followed by 0.297 for colorectal cancer ( N=3, n=12), 0.356 for stomach cancer ( N=1, n=4) and 0.896 for breast cancer ( N=6, n=52, P75=3.602). When based on another commonly used ICER indicator, the median ratio of cost per quality-adjusted life-year gained to China′s per capita GDP (reported in 13 studies), the least cost was found in stomach cancer (0.495, N=3, n=8, P75=3.126), followed by esophageal cancer (0.960, N=1, n=4, P75=1.762) and breast cancer (2.056, N=9, n=64, P75=4.217). Data was not found for colorectal cancer. In addition, cost per cancer case detected was the most adopted indicator (32 studies). The median cost among all screening strategies for each cancer was 14 759 CNY for stomach cancer ( N=5, n=7), 49 680 CNY for colorectal cancer ( N=12, n=25) and 171 930 CNY for breast cancer ( N=13, n=24), respectively. Data was not available for esophageal cancer and rare for precancer cases detected. Evidence related to cost per disability-adjusted life-year gained was not available. Conclusions:At China′s national level and limited to the six cancers covered by the current study, the preliminary analysis suggests that stomach cancer and colorectal cancer were the most cost-effective target cancers and could be given priority in the future scaled-up screening in general populations. Esophageal cancer screening should be prioritized in high-risk areas. Breast cancer was also cost-effective in general but some of the intensive screening strategies were marginal. Data on liver cancer and lung cancer were too limited to conclude, and more well-designed studies and high-quality research evidence should be required. This priority ranking might be changed if other common cancers were involved analyses.

We hereby reported the diagnosis, treatment process and perinatal outcome of a patient with novel coronavirus infection in perinatal period. The pregnant woman delivered a boy by cesarean section at 37⁺² gestational weeks due to severe liver dysfunction. She subsequently had a high fever 2 days later, and novel coronavirus infection was confirmed by nucleic acid test in a throat swab. After a 12-day isolation and support treatment, her two consecutive throat swab results for novel coronavirus turned negative and she was discharged. The novel coronavirus was tested in the patient's blood, urine, breast milk as well as the neonatal throat swab, and the results were all negative. The neonate had an elevated myocardial enzyme, but was otherwise well and was discharged after 14-day isolation with normal myocardial enzyme.
