General anesthesia, pivotal for surgical procedures, requires precise depth monitoring to mitigate risks ranging from intraoperative awareness to postoperative cognitive impairments. Traditional assessment methods, relying on physiological indicators or behavioral responses, fall short of accurately capturing the nuanced states of unconsciousness. This study introduces a machine learning-based approach to decode anesthesia depth, leveraging EEG data across different anesthesia states induced by propofol and esketamine in rats. Our findings demonstrate the model's robust predictive accuracy, underscored by a novel intra-subject dataset partitioning and a 5-fold cross-validation method. The research diverges from conventional monitoring by utilizing anesthetic infusion rates as objective indicators of anesthesia states, highlighting distinct EEG patterns and enhancing prediction accuracy. Moreover, the model's ability to generalize across individuals suggests its potential for broad clinical application, distinguishing between anesthetic agents and their depths. Despite relying on rat EEG data, which poses questions about real-world applicability, our approach marks a significant advance in anesthesia monitoring.

The occurrence of benign prostate hyperplasia(BPH)was related to disrupted sex steroid hormones,and metformin(Met)had a clinical response to sex steroid hormone-related gynaecological disease.How-ever,whether Met exerts an antiproliferative effect on BPH via sex steroid hormones remains unclear.Here,our clinical study showed that along with prostatic epithelial cell(PEC)proliferation,sex steroid hormones were dysregulated in the serum and prostate of BPH patients.As the major contributor to dysregulated sex steroid hormones,elevated dihydrotestosterone(DHT)had a significant positive rela-tionship with the clinical characteristics of BPH patients.Activation of adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK)by Met restored dysregulated sex steroid hormone homeostasis and exerted antiproliferative effects against DHT-induced proliferation by inhibiting the formation of androgen receptor(AR)-mediated Yes-associated protein(YAP1)-TEA domain transcription factor(TEAD4)heterodimers.Met's anti-proliferative effects were blocked by AMPK inhibitor or YAP1 over-expression in DHT-cultured BPH-1 cells.Our findings indicated that Met would be a promising clinical therapeutic approach for BPH by inhibiting dysregulated steroid hormone-induced PEC proliferation.

【Objective】 To explore the effect of physical fitness training on social adaptive behavior of children with global developmental delay (GDD), in order to provide treatment experience for GDD children. 【Methods】 From November 2021 to December 2022, a total of 60 children with GDD diagnosed and treated in the Third Affiliated Hospital of Jiamusi University were enrolled in this study, and were randomly divided into control group (n=30) and test group (n=30).The control group received routine rehabilitation treatment, and the test group received physical fitness training additionally.The intervention lasted for 12 weeks, with the frequency of 3times/week, 30min/time.All subjects were tested for physical fitness and children′s social adaptive behavior before and after training. 【Results】 Before treatment, the difference between the results of physical fitness test and social adaptive behavior scores of the GDD children in two groups was not statistically significant (P>0.05).After 3 months of treatment, the physical fitness test scores, except body mass index (BMI), and social adaptive behavior scores of the GDD children in two groups were significantly different from those before treatment (P<0.05), and the physical fitness test scores (except for height, weight and BMI) and the social adaptive behavior of the test group were better than those of the control group (t=2.363,4.020,3.331,3.338,P<0.05). 【Conclusion】 Physical fitness training can significantly improve the adaptive behavior, independent function, cognitive function and social/self-control ability of GDD children.

Objectives:To analyze the clinical prognosis stratification of fetal heart disease(FHD)and the mid-term follow-up results following integrated prenatal and postnatal management. Methods:Present retrospective analysis was performed on 817 fetuses diagnosed with FHD by fetal echocardiography in Fuwai Hospital,Chinese Academy of Medical Sciences(Fuwai Hospital)from the 8th February 2018 to 30th April 2022.According to the Chinese expert consensus on fetal prognosis score of congenital heart disease(CHD)and Fuwai Hospital Pediatric Center score,FHD was divided into grade Ⅰ(0 point),grade Ⅱ(1-3 points),grade Ⅲ(4-6 points)and grade Ⅳ(7-9 points).For FHD fetuses that need to be treated in the neonatal period,the whole closed-loop management and treatment were completed,including pregnancy,birth,neonatal monitoring,surgery,and follow-up.The clinical data and mid-term follow-up results of FHD fetuses were analyzed. Results:A total of 752 fetuses completed the mid-term follow-up.The mean follow-up time was(18.5±2.3)months.There were 111 cases(14.8%)of FHD grade Ⅰ,251 cases(33.4%)of FHD grade Ⅱ,275 cases(33.6%)of FHD grade Ⅲ and 115 cases(15.3%)of FHD grade Ⅳ.There were 393 cases(52.2%)of fetal preservation,1 case(0.2%)of intrauterine death,and 358 cases(47.6%)of induced abortion.Compared with the induced fetus,the pregnant women in the reserved fetus group were older,the gestational age was longer,the rate of receiving noninvasive DNA and amniocentesis was lower,the proportion of chromosomal abnormalities or genetic abnormalities was smaller,and the FHD prognostic score was lower(all P<0.05).One case(0.9%)of FHD grade Ⅰ fetus experienced intrauterine fetal death,and 110 cases(99.1%)were born and recovered.164 cases(65.3%)of grade Ⅱ fetuses were born,and all of them were cured by surgery or spontaneously.118 cases(42.9%)of grade Ⅲ fetuses were born,117 cases completed biventricular radical operation,and 1 case completed two-stage operation waiting for the second stage biventricular radical operation.One case(0.9%)of grade Ⅳ was born and completed the two-stage bidirectional Glenn procedure.Among the induced FHD grade Ⅱ fetuses,8(9.2%)had abnormal chromosomal or genetic testing results,and 8(9.2%)had other organ abnormalities.Among the induced FHD grade Ⅲ fetuses,5 cases(3.2%)had chromosomal abnormalities,5 cases(3.2%)had genetic abnormalities,and 9 cases(5.7%)had other organ abnormalities.There was only one case(0.9%)of FHD Ⅳ with hypoplastic left heart syndrome,which was retained as one of the twins and was born successfully.Norwood one-stage procedure was performed in the neonatal period,and two-stage bidirectional Greene procedure was performed at 6 months after birth.Other fetuses were induced following the choice of maternity and their family members. Conclusions:Hierarchical management based on clinical prognosis is helpful to scientifically guide the integrated treatment of FHD fetuses and improve the success rate of treatment of FHD fetuses with good prognosis.

Objectives:To summarize the experience of echocardiographic diagnosis and the short-term post-operative outcome of children with cardiac tumors. Methods:A total of 27 infants and children,who underwent echocardiography examination and were preliminarily diagnosed with cardiac tumors in Fuwai Hospital from January 2018 to June 2023,were retrospectively included in this study.Clinical symptoms,echocardiographic results,surgical and perioperative results and early outcomes were analyzed. Results:Among the 27 patients,16 were males.The age ranged from 1 month to 11 years(mean age:[3.2±2.5]years)and the body weight ranged from 5.7 to 40.0 kg(mean body weight:[17.2±11.2]kg).Cardiac tumors were pathologically confirmed in 25 cases,including 14 cases of fibroma,5 cases of rhabdomyoma,3 cases of myxoma,2 cases of lipoma,1 case of hemangioma.Preoperative echocardiographic diagnosis was consistent with postoperative pathologic diagnosis in 14 cases.Nontumor lesions were misdiagnosed as tumors by echocardiography in 2 cases.All the patients underwent surgery,complications occurred in 2 cases early post surgery and underwent reoperations and recovered well.There were no deaths during a median follow-up of 29.8(6.5,72.0)months,recurrence occurred in one child with myxoma. Conclusions:Pediatric patients with cardiac tumors have specific echocardiographic manifestations.It is necessary to sum up related experience constantly to improve the diagnostic accuracy.Short-term outcome post-surgery is satisfactory for the treatment of benign pediatric cardiac tumors.

In the process of animal fat deposition, the proliferation and differentiation of pre-adipocytes and the change of lipid droplet content in adipocytes are regulated by a series of transcription factors and signal pathways. Although researchers have conducted in-depth studies on the transcriptional regulation mechanisms of adipogenesis, there are relatively few reports on post-transcriptional modification on mRNA levels. The modification of mRNA m⁶A regulated by methyltransferase, demethylase and methylation reading protein is a dynamic and reversible process, which is closely related to fat deposition in animals. Fat mass and obesity associated proteins (FTO) act as RNA demethylases that affect the expression of modified genes and play a key role in fat deposition. This article summarized the mechanism of FTO-mediated demethylation of mRNA m⁶A in the process of animal fat deposition, suggesting that FTO may become a target for effective treatment of obesity. Moreover, this review summarized the development of FTO inhibitors in recent years.

Objective:To investigate the association of body mass index (BMI), blood lipid, serum leptin, adiponectin with papillary thyroid carcinoma.Methods:A total of 120 patients including 40 cases of papillary thyroid carcinoma (papillary thyroid carcinoma group), 40 cases of nodular goiter (nodular goiter group) and 40 cases diagnosed without thyroid diseases or other metabolic diseases during the corresponding period (the control group) in Inner Mongolia People's Hospital from April 2015 to January 2016 were enrolled. The BMI of all subjects was calculated. The levels of blood lipid, serum leptin and adiponectin were detected.Results:The number of females was more than that of males in nodular goiter group and papillary thyroid carcinoma group, and the difference in gender distribution of three groups was statistically significant (χ 2 = 19.024, P < 0.01). The level of BMI, leptin, triglyceride and total cholesterol of papillary thyroid carcinoma group was higher than that of the control group [(24.86±3.26) kg/m 2 vs. (20.79±2.15) kg/m 2, (0.68±0.07) ng/ml vs. (0.61±0.39) ng/ml, (1.42±0.53) mmol/L vs. (1.05±0.36) mmol/L, (4.76±0.57) mmol/L vs.(4.28±0.46) mmol/L], and the differences were statistically significant ( t values were 4.302, 3.296, 1.993 and 2.177, respectively, all P < 0.05). The level of total cholesterol and low-density lipoprotein [(4.97±0.55) mmol/L, (2.72±0.58) mmol/L] in the nodular goiter group was higher than that in the control group [(4.28±0.46) mmol/L, (2.18±0.69) mmol/L], and the differences were statistically significant ( t values were 2.954 and 2.148, respectively; all P < 0.05). The level of adiponectin [(4.21±0.34) ng/ml, (4.30±0.27) ng/ml] in papillary thyroid carcinoma and nodular goiter group was lower than that in the control group [(4.87±0.27) ng/ml], and the differences were statistically significant ( t values were 7.631 and 7.416, respectively; all P < 0.05). Conclusion:The increase of BMI, triglyceride, total cholesterol, serum leptin and the decrease of serum adiponectin may be related to the occurrence of papillary thyroid carcinoma.

Objective:To explore the relationship between somatic symptoms of major depressive disorder(MDD)and cortisol(COR) rhythm, C-reactive protein(CRP) and other immune-metabolism-related indicators, and understand its mechanism from the perspective of endocrine and immune regulation.Methods:A case-control study was conducted in hospitalized patients with MDD who met DSM-5 diagnostic criteria.According to the Patient Health Questionnaire (PHQ-15), PHQ-15 ≥10 were classified as the somatic major depressive disorder group(S-MDD group) and 73 patients were enrolled.PHQ-15 <5 was classified as the non-somatic depressive disorder group (NS-MDD group) and 70 patients were enrolled.Plasma cortisol (COR8, COR16 and COR24) levels were measured at 8∶00, 16∶00 and 24∶00 on the same day, plasma CRP and interleukin-6 (IL-6) level, serum uric acid (UA), blood glucose (GLU), blood lipid (TC, TG, HDL, LDL) level were detected at 8∶00.Independent sample t test, non-parametric test, chi-square test, repeated ANOVA, covariance analysis, and multivariate Logistic regression were used for statistical analysis. Results:①Time effect, grouping effect and the interaction effect of the time and grouping in the level of COR were statistically significant ( P<0.05). Covariance analysis excluded age as an influential factor, COR16, AUC(total cortisol output/area under the curve, AUC) and COR8-16 in S-MDD group ((90.50±40.57)μg/L, (1 425.12±564.78), (-6.43±5.76))were higher than those in NS-MDD group((68.74±31.51)μg/L, (1 251.57±456.61), (-8.77±5.48)), and the difference was statistically significant ( F=8.971, 4.320, 8.731, P<0.05). ②CRP in S-MDD group ((1.41±1.06)mg/L) were higher than that in NS-MDD group((0.61±0.53)mg/L), and the difference was statistically significant ( F=25.436, P<0.05). The proportion of patients with higher CRP level(CRP≥1 mg/L) in S-MDD group(58%) was higher than that in NS-MDD group(23%), and the difference was statistically significant(χ 2=17.824, P<0.01). ③Multivariate logistic regression analysis found that CRP ( OR=4.953, 95% CI: 2.407-10.193), COR8-16 ( OR=3.451, 95% CI: 1.380-8.633) were main risk factors of somatic symptoms of MDD ( P<0.05). Conclusion:Cortisol rhythm disturbance and high CRP level may be the biological basis of somatic symptoms in patients with MDD.

Objective:To review the patients with supramitral ring (SMR) and summary echocardiographic features and operative prognosis in these patients.Methods:Clinical and echocardiographic data of 53 patients with SMR treated in Fuwai Hospital from Jan 2016 to Jan 2020 were reviewed. Patients were divided into simple group( n=28) and complex group( n=25) based on mitral apparatus normal or not. The echocardiographic characteristics, morphology of the rings, procedure′s results and follow-up data were recorded and assessed. Results:There was no significant difference in age, peak and mean mitral value(MV) gradient before surgery between the two groups (all P>0.05). Patients with mitral regurgitation and left outflow tract obstruction in complex group were more than in simple group (all P<0.05). All patients underwent cardiac operation. The average follow-up were(14.69±11.14)months. The overall missed diagnosis was 13%. The missed diagnosis rate in complex group was higher(20% vs 7%). The peak and mean MV gradient in all patients after surgery were reduced (all P<0.05), but the gradients in complex group were higher than simple group(all P<0.05). Restensis occurred in 3 patients in each group after surgery, in which 3 patients in complex group accepted reoperation. Conclusions:Echocardiography can diagnose different types of SMR and associated malformations, evaluate surgical outcomes, and follow up for recurrence of SMR. Patients with simple SMR have better surgical results, but there is still a certain recurrence rate of stenosis.
