AIM: To analyze the recovery of stereopsis and its influencing factors in children with intermittent exotropia(IXT)after binocular vision training.METHODS: A total of 166 cases of IXT children who were treated in our hospital from October 2021 to October 2023(2 cases lost their follow-up, and 164 cases were finally included)were included as the research object, taking 36 cases with no stereopsis after binocular vision training in eye position correction surgery as no stereopsis group, and other 128 cases as stereopsis group. All the children underwent eye position correction surgery under general anesthesia, and all received binocular vision training for 6 mo after surgery. The recovery of stereoscopic vision of IXT children after binocular vision training was counted, and the influencing factors of stereoscopic vision recovery of IXT children after binocular vision training were analyzed by single factor and multi-factor Logistic regression analysis.RESULTS: The incidence of postoperative no stereopsis was 22.0%. The proportion of children with an age ≥9 years old, course of disease ≥1 a and anisometropia in the group without stereoscopic vision after operation was larger than the group with stereoscopic vision(all P<0.05). Multivariate Logistic regression analysis showed that the course of disease ≥1 a, age ≥9 years old and anisometropia were independent influencing factors for the recovery of stereoscopic vision in IXT children after binocular vision training(OR=1.470, 1.626, 1.539, all P<0.05).CONCLUSION: Age ≥9 years old, course of disease ≥1 a, and anisometropia are the independent influencing factors of stereopsis recovery of IXT children after binocular vision training. Therefore, targeted intervention measures can be given to high-risk children to improve the stereopsis recovery of IXT children after binocular vision training.

ObjectiveTo explore new targets and herbal medicines of total ginsenosides in ameliorating alcoholic hepatitis （AH） by data mining and experimental validation and to provide new directions for the clinical treatment of AH. MethodGSE28619 was selected as the test set from the GEO database and GSE83148 and GSE103580 were selected as the validation sets. The limma package and weighted gene co-expression network analysis （WGCNA） were employed to identify the AH-related differentially expressed genes and modular genes， and Venny was used to extract the common genes. The protein-protein interaction （PPI） network was constructed and the enrichment analysis was carried out. The hub genes were further screened and evaluated for their diagnostic value. After validation with the datasets， new potential targets of AH and traditional Chinese medicine were predicted. Molecular docking between the targets and active ingredients of traditional Chinese medicine was performed， and the results were validated by experiments. Eight out of 48 SD rats were randomly selected into a blank group and received an equal amount of normal saline. The rest rats were subjected to modeling with ethanol by gavage and then randomized into low- （10 mg·kg^-1）， medium- （20 mg·kg^-1）， and high-dose （40 mg·kg^-1） total ginsenosides， model， and positive control （metadoxine， 117 mg·kg^-1） groups. After 3 weeks of gavage， serum samples were collected for the measurement of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） levels， and liver samples were collected for hematoxylin-eosin （HE） staining. Western blot and Real-time PCR were employed to determine the protein and mRNA levels， respectively， of potential targets in the liver tissue. ResultData mining predicted the potential genes： Proto-oncogene FOS and collagen type Ⅰ alpha 2 （COL1A2）. Experimental validation showed that the liver injury was alleviated after drug administration compared with that after modeling. The serum AST and ALT levels were reduced after drug administration. The protein and mRNA levels of FOS were significantly up-regulated， while those of COL1A2 were down-regulated after drug administration. ConclusionTotal ginsenosides ameliorate HA via FOS and COL1A2.

Objective:To summarize the clinical characteristics of patients with renal angiomyolipoma(RAML)combined with inferior vena cava(IVC)tumor thrombus,and to explore the feasibility of par-tial nephrectomy and thrombectomy in this series of patients.Methods:The clinical data of patients diagnosed with RAML combined with IVC tumor thrombus in the Department of Urology of the Peking University Third Hospital from April 2014 to March 2023 were retrospectively analyzed,and demographic and perioperative data of RAML patients with IVC tumor thrombus were recorded and collected from Elec-tronic Medical Record System,including age,gender,surgical methods,and follow-up time,etc.The clinical characteristics between classic angiomyolipoma(CAML)patients with IVC tumor thrombus and epithelioid angiomyolipoma(EAML)patients with IVC tumor thrombus were compared to determine the clinical characteristics of these patients.Results:A total of 11 patients were included in this study,in-cluding 7 patients with CAML with IVC tumor thrombus and 4 patients with EAML with IVC tumor thrombus.There were 9 females(9/11,81.8％)and 2 males(2/11,18.2％),with an average age of(44.0±17.1)years.9 patients(9/11,81.8％)experienced clinical symptoms,including local symp-toms including abdominal pain,hematuria,abdominal masses,and systemic symptoms including weight loss and fever;2 patients(2/11,18.2％)with RAML and IVC tumor thrombus did not show clinical symptoms,which were discovered by physical examination.Among the 11 patients,10 underwent radical nephrectomy with thrombectomy,of whom,3 underwent open surgery(3/10,30.0％),2 underwent laparoscopic surgery(2/10,20.0％),and 5 underwent robot-assisted laparoscopic surgery(5/10,50.0％).In addition,1 patient underwent open partial nephrectomy and thrombectomy.The patients with EAML combined with I VC tumor thrombus had a higher proportion of systemic clinical symptoms(100％vs.0％,P=0.003),more intraoperative bleeding[400(240,3 050)mL vs.50(50,300)mL,P=0.036],and a higher proportion of tumor necrosis(75％vs.0％,P=0.024)compared to the patients with CAML combined with I VC tumor thrombus.However,there was no statistically significant difference in operation time[(415.8±201.2)min vs.(226.0±87.3)min,P=0.053]between the two groups.Conclusion:Compared with the patients with CAML and IVC tumor thrombus,the patients with EAML and IVC tumor thrombus had a higher rate of systemic symptoms and tumor necrosis.In addi-tion,in the selected patients with CAML with IVC tumor thrombus,partial nephrectomy and tumor thrombectomy could be performed to better preserve renal function.

Objective To investigate the role of silencing regulatory protein 1(Sirt1)in the regulation of Vibrio vulnificus sepsis-induced macrophage apoptosis and the molecular mechanisms.Methods Mouse RAW264.7 macrophages which stably overexpressed Sirt1 were constructed and screened by genistein G418.CCK-8 analysis was used to detect the proliferation of cells in the control group and Sirt1-Flag group.The changes of expression levels of apoptosis-associated protein poly ADP-ribose polymerase(PARP),cleaved-PARP,caspase3,cleaved-caspase3 and acetylated p53 in different treatment groups were detected via Western blotting.A Vibrio vulnificus sepsis model in mice was established,and the expression levels of apoptosis-associated protein cleaved-caspase3 in the lung,spleen and liver of mice of different treatment groups were detected by immunohistochemistry.Results Overexpression of Sirt1 reduced VVC-induced RAW264.7 cell damage.Overexpression of Sirt1 as well as RSV pretreatment lowered the expression of apoptosis-associated protein cleaved-PARP,cleaved-caspase3 and acetylated p53 in VVC-stimulated RAW264.7 cells and mouse peritoneal macrophages.In the mouse model of Vibrio vulnificus sepsis,therapeutic administration of RSV reduced the expression of apoptosis-associated protein marker cleaved-caspase3 in lung,spleen and liver tissues.Conclusion Sirt1 can inhibit p53 acetylation and reduces apoptosis in mouse macrophages,which helps protect against Vibrio vulnificus sepsis.

Objective:This study aimed to explore the clinical value of myostatin(MST) and follistatin(FST) as biological biomarkers in evaluating sarcopenia in elderly women.Methods:This was a retrospective cross-sectional study that enrolled 350 females aged 20-89 years who underwent physical examinations in Shanghai Huadong Hospital in 2021. Demographic characteristics, muscle mass, fat mass, bone mineral density, hand grip strength, gait speed, and serum indices of MST and FST were collected.Results:The serum levels of MST did not change significantly with age. However, the serum levels of FST increased with age. In women aged≥60 years, MST was positively correlated with total lean mass and appendicular skeletal muscle index(ASMI; r=0.236, P=0.041; r=0.289, P=0.014), while FST was negatively correlated with ASMI( r=-0.265, P=0.030). In multivariate stepwise regression analysis, after adjusting for age, body mass index, hip bone mineral density, and total fat mass, only FST was independently correlated with ASMI( β=-0.238, P=0.006), while MST was not correlated with ASMI. The receiver operating characteristic curve was plotted using muscle mass reduction as the state variable and serum FST level as the test variable. The area under the curve was 0.753. And when the FST cutoff value was 17.49 ng/mL, the maximum Jordan index was 0.46, with a sensitivity of 77.3% and a specificity of 68.7%. Women aged ≥60 years were divided into three groups based on serum FST levels. Compared to the upper third of the serum FST level group, the low third of the FST level group had a significantly reduced risk of suffering from sarcopenia( OR=0.098, P =0.036). Conclusions:Serum FST lever has a better correlation with muscle mass among elderly women, making it a promising biomarker for evaluating muscle mass.

Objective:To discuss the efficacy and safety of stereotactic electroencephalography (SEEG) in epileptogenic foci excision in pediatric patients with drug-resistant epilepsy.Methods:A total of 126 pediatric patients (<18 years old) with drug-refractory epilepsy who received SEEG-guided epileptogenic foci excision in Epilepsy Center, Aviation General Hospital from January 2015 to March 2022 were selected. The clinical data and efficacy were retrospectively analyzed, and prognoses of these pediatric patients were evaluated by Engel grading 1 year after resection.Results:(1) A total of 1289 electrodes were implanted, with a mean of (10.09±2.92) electrodes per pediatric patient; 55 pediatric patients had unilateral implant and 71 had bilateral implant. Mean EEG monitoring time was (8.69±5.71) d, ranged 3-28 d. Epileptogenic focus could be located in 114 pediatric patients (90.5%) after initial implantation under SEEG monitoring, and secondary implantation for accurate positioning was given in 12 pediatric patients (9.5%). (2) Lobectomy was performed in 27 pediatric patients (21.4%), multi-lobectomy or tailored cortical resection in 36 (28.6%), tailored cortical resection on single lobe in 60 (47.6%), and tailored cortical resections on single lobe or hippocampal amygdala resection combined with corpus callosotomy in 3 (2.4%). Minimally invasive exploring hemostasis under SEEG was performed in 13 pediatric patients (17 electrodes) and postoperative CT was normal. A little asymptomatic epidural, subdural or cerebral parenchymal hematoma spontaneously absorbed was noted in 4 pediatric patients after implantation under SEEG monitoring. No perioperative infection, CSF leakage, death or severe disability was noted. (3) Mean follow-up was performed for (26.1±7.26) months; 66 (52.3%) pediatric patients reached Engel grading I, 33 (26.2%) reached Engel grading II, 21 reached Engel grading III (16.7%), and 6 (4.8%) reached Engel grading IV. Thirteen pediatric patients with failed resection received SEEG-guided epileptogenic foci excision for the second time: 8 (76.9%) had Engel grading I and 2 had Engel grading II 1 year after follow-up, accounting for 76.9% totally.Conclusion:SEEG-guided epileptogenic foci excision is safe and effective in drug-refractory epilepsy; for pediatric patients with poor initial results, SEEG can be used to relocate the epileptogenic focus, and a second resection of epileptogenic focus can also obtain good results.

Objective:To explore the clinical efficacy of adult donor dual kidney transplantation.Methods:Retrospective analysis of case data of 13 adult donor kidney dual kidney transplantation (DKT) performed in the The Second Xiangya Hospital of Central South University from September 2016 to December 2020. For 13 donors, the average age and BMI were (53.5±12.4)years and (24.3±2.8) kg/m 2, respectively. Their mean Serum creatinine (SCr) at admission and before procurement was (132.9±54.1)and (228.7±112.4)μmol/L, respectively. 3 of them had diabetes mellitus history, and 8 had hypertension history. 11 met the United Network for Organ Sharing (UNOS) DKT criteria and 6 met Remuzzi score DKT criteria. For 13 recipients, the average age and BMI were (39.3±8.9)years and (20.2±2.4)kg/m 2, respectively. All of them received ABO blood type-matched kidney transplants. 2 of them had their grafts transplanted in the bilateral iliac. In 12 cases, the grafts filled rapidly and urinated immediately when opening blood flow. In 1 case, the grafts were dark in color and vascular showed weak pulsation after opening blood flow. The time to recovery of perioperative graft function (from the day of surgery to the natural reduction of SCr to the normal range 44-133μmol/L), the occurrence of delayed graft function (DGF), acute rejection (AR), ureteral and surgical incision complications, as well as the recipients’ final follow-up SCr, eGFR, urinary protein, and grafts outcome were observed. Risk factors affecting outcomes were assessed by univariate logistic regression analysis. Results:The SCr dropped to the normal range at discharge in 10 recipients, and the average recovery time was (13.8±13.0) days. In other 3 cases SCr at discharge were 300.0, 149.0, 152.5μmol/L. 4 cases had DGF, 4 had AR, 1 experienced urinary fistula, and 1 experienced incisional dehiscence, which were treated with anti-rejection, J-tube implantation, continuous catheterization to maintain bladder void, secondary suturing, respectively. The follow-up time ranged from 4 to 54 months, with a median of 28(15.5, 31.0) months. At the final follow-up time, 10 cases had good graft function, 2 suffered impaired kidney function, and 1 experienced graft failure. The average SCr and eGFR except for graft failure patient were (144.2±101.3)μmol/L and (52.9±21.2)ml/min, respectively. 4 had positive urine protein. Univariate logistic regression analysis showed that donor age, BMI, history of diabetes mellitus and hypertension, and SCr were not significantly correlated with recipients’ DGF and graft impairment ( P>0.05), and due to the small sample size, multifactorial logistic regression analysis was not performed. Conclusion:The short to medium-term effects of adult donor DKT coule be safe and feasible.

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.

【Objective】 To establish a co-expression lncRNA-mRNA ceRNA network and explore the potential molecular mechanism of lncRNA in dengue fever. 【Methods】 DENV-2-infected and normal pHUVEC were sequenced and screened for differentially expressed lncRNA and mRNA by gene microarray technology. Differentially expressed mRNA was analyzed by protein-protein interaction (PPI), and significantly related co-expressed lncRNA-mRNA was screened by Pearson’s correlation coefficient. The microRNA (miRNA) that bound to co-expressed lncRNA-mRNA was predicted by the database. The ceRNA network of co-expressed lncRNA-mRNA was constructed by Cytoscape software. Finally differentially expressed mRNAs and co-expressed lncRNA-mRNA were analyzed by GO and KEGG enrichment, and co-expressed lncRNA-mRNA was verified by RT-qPCR. 【Results】 At 48 h and 72 h after infection, 105 and 51 differentially expressed mRNAs were obtained, respectively, while 59 and 29 differentially expressed lncRNAs were obtained, respectively. Furthermore, at the two time intervals, there were 10 differential mRNAs and 5 differential lncRNAs, respectively. PPI analysis of differential mRNAs showed that isocratic values of interleukin 6 (IL6), interferon-induced protein with tetratricopeptide repeats 2 (IFIT2), and 2’-5’-oligoadenylate synthetase 2 (OAS2) were relatively high. The pairing results of lncRNA-mRNA co-expression analysis with the highest correlation coefficients at 48 h and 72 h after infection were XLOC_001966-SMTNL1 and XLOC_001966-ESR2, respectively. According to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis, the functions of differentially expressed mRNA and co-expressed lncRNA-mRNA were mainly involved in virus epidemic prevention response, immune response, and signal transduction, as well as the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) signaling pathway, type I interferon, and cytokine receptor interaction. RT-qPCR revealed that lncRNA XLOC-I2-8991 was upregulated in the co-expressed lncRNA-mRNA, whereas all the other lncRNA and mRNA were downregulated. 【Conclusion】 This study initially revealed the potential lncRNA-mRNA co-expression network during dengue virus infection, and found that co-expressed lncRNA-mRNA was mainly enriched in the immune regulation and signal transduction pathways during virus infection. The findings will help further exploration into the infection mechanism of DENV-2.

BACKGROUND: Distinguishing between primary clear cell carcinoma of the liver (PCCCL) and common hepatocellular carcinoma (CHCC) through traditional inspection methods before the operation is difficult. This study aimed to establish a Faster region-based convolutional neural network (RCNN) model for the accurate differential diagnosis of PCCCL and CHCC. METHODS: In this study, we collected the data of 62 patients with PCCCL and 1079 patients with CHCC in Beijing YouAn Hospital from June 2012 to May 2020. A total of 109 patients with CHCC and 42 patients with PCCCL were randomly divided into the training validation set and the test set in a ratio of 4:1.The Faster RCNN was used for deep learning of patients' data in the training validation set, and established a convolutional neural network model to distinguish PCCCL and CHCC. The accuracy, average precision, and the recall of the model for diagnosing PCCCL and CHCC were used to evaluate the detection performance of the Faster RCNN algorithm. RESULTS: A total of 4392 images of 121 patients (1032 images of 33 patients with PCCCL and 3360 images of 88 patients with CHCC) were uesd in test set for deep learning and establishing the model, and 1072 images of 30 patients (320 images of nine patients with PCCCL and 752 images of 21 patients with CHCC) were used to test the model. The accuracy of the model for accurately diagnosing PCCCL and CHCC was 0.962 (95% confidence interval [CI]: 0.931-0.992). The average precision of the model for diagnosing PCCCL was 0.908 (95% CI: 0.823-0.993) and that for diagnosing CHCC was 0.907 (95% CI: 0.823-0.993). The recall of the model for diagnosing PCCCL was 0.951 (95% CI: 0.916-0.985) and that for diagnosing CHCC was 0.960 (95% CI: 0.854-0.962). The time to make a diagnosis using the model took an average of 4 s for each patient. CONCLUSION The Faster RCNN model can accurately distinguish PCCCL and CHCC. This model could be important for clinicians to make appropriate treatment plans for patients with PCCCL or CHCC.
