ObjectiveTo investigate the effect of multi-target transcranial direct current stimulation (tDCS) and single-target tDCS on the performance of working memory-postural control dual-task in healthy adults, and to compare the regulatory effect of the two stimulation protocols. MethodsFrom November, 2020 to February, 2021, 19 healthy adults in Shanghai University of Sport were recruited and randomly accepted multi-target tDCS, single-target tDCS and sham stimulation with at least one week interval between any two stimulation protocols. The target areas of multi-target tDCS included left dorsal lateral prefrontal cortex (L-DLPFC) and bilateral primary motor cortex (M1), and single-tDCS only applied to L-DLPFC. Before and after stimulation, participants completed walking and standing balance tests under single task and dual-task conditions with the second task being a N-back task. The dual-task postural control performance, dual-task cost (DTC) and working memory performance were observed before and after stimulation. ResultsSignificant differences were observed among three stimulation protocols in the changes of stride variability (F = 3.792, P = 0.029), DTC of stride variability (F = 3.412, P = 0.040) and velocity of center of pressure (Vcop) (F = 3.815, P = 0.029). The stride variability (P = 0.047) and Vcop (P = 0.015) were significantly lower and the decrease in DTC of stride variability tended to be significant (P = 0.073) following multi-target tDCS, as compared to sham stimulation. Single-target tDCS significantly decreased the changes of stride variability (P = 0.011), DTC of stride variability (P = 0.014) and Vcop (P = 0.025), as compared to sham stimulation. Compared with single target tDCS, multi-target tDCS reduced the changes of the dual-task cost of the area of center of pressure (P = 0.035). Moreover, no significant difference was observed among the three stimulation protocols in the changes of each measure in the working memory test (P > 0.05). ConclusionBoth multi-target tDCS and single-target tDCS can improve the performance of working memory-postural control dual-task in healthy adults, and compared with single-target tDCS, multi-target tDCS has some advantages in regulating postural control.

【Objective】 To explore the diagnostic value of platelet long non-coding RNA (lncRNA) as a biomarker for early screening of lung adenocarcinoma (LUAD). 【Methods】 The GSE183635 and GSE89843 datasets, which contained the platelet transcriptome of LUAD and healthy controls, were used for differential analysis, and the intersection of the differentially expressed lncRNA(DElncRNA) of the two datasets was taken. The expression levels of DElncRNA in LUAD tissues and normal control tissues were analyzed using GEPIA2. The expression levels of LINC01088 in platelets of 51 healthy controls and 54 LUAD patients were detected by quantitative Real-time PCR (qRT-PCR), and the diagnostic ability of each index was evaluated by ROC curve. 【Results】 8 DElncRNAs and 1 265 DElncRNAs were obtained from GSE183635 and GSE89843 datasets, respectively. The key DElncRNA LINC01088 was selected after intersection. GEPIA2 analysis showed that the expression level of LINC01088 in LUAD tissues was lower than that in normal lung tissues (P<0.05). Platelet LINC01088 was significantly downregulated in patients with LUAD and early-stage LUAD than in healthy controls(P<0.001). The area under the curve (AUC) of platelet LINC01088 in the diagnosis of LUAD was 0.755, the sensitivity was 81.1%, and the specificity was 67.9%. The AUC for early LUAD diagnosis was 0.727, the sensitivity was 80.0%, and the specificity was 67.9%. The AUC of the combined diagnostic model composed of platelet LINC01088 and carcinoembryonic antigen (CEA) for LUAD diagnosis was 0.807, the sensitivity was 89.2%, and the specificity was 71.4%. The AUC for early LUAD was 0.770, the sensitivity was 86.7%, and the specificity was 71.4%. The combined diagnostic model of platelet LINC01088 and CEA was superior to CEA in the diagnosis of LUAD and early LUAD (Z=-2.288, -2.34, both P<0.05). 【Conclusion】 LINC01088 is down-regulated in platelets of LUAD patients. Platelet LINC01088 may be a biomarker for early screening and diagnosis of LUAD.

Major depressive disorder (MDD) has become an increasingly serious public health issue, characterized by high incidence and high disability rates. It often coexists with other mental health problems and physical diseases, with a significant negative impact on patients' quality of life. In clinical practice, MDD is considered a heterogeneous disease. The complexity of the pathological mechanisms and the variability in treatment responses lead to a lack of clear therapeutic targets, which complicates the treatment process. In recent years, with advancements in neuroscience, the crucial role of microglia in the pathogenesis of MDD has been revealed. As the main immune cells in the brain, microglia are not only involved in the regulation of neuroinflammation but also play important roles in neurogenesis and neuronal regulation in MDD. This article mainly discusses the role of microglia in the pathophysiological mechanisms of MDD, aiming to provide a theoretical basis for microglia as a potential target for the treatment of MDD.

Objective:To understand the epidemiological characteristics and spatiotemporal distribution of viral encephalitis in children and adolescents in Henan Province from 2012 to 2023.Methods:The information about viral encephalitis cases from October 1, 2012 to July 26, 2023 were collected from Zhengzhou Children's Hospital (National Children's Regional Medical Center),Henan Provincial Children's Hospital for the analyses on temporal distribution the cases, the severe illness rate, age distribution, pathogen type and imaging findings of the cases.Results:A total of 6 276 cases of viral encephalitis were included in this study after excluding cases with incomplete information. The cases mainly originated from Zhengzhou (38.96%), followed by Zhoukou (9.93%), Xuchang (8.68%), Zhumadian (7.90%) and Pingdingshan (7.39%). The cases in boys accounted for 62.13% and the cases in girls accounted for 37.87%. Most cases (72.45%) occurred in age group 7-13 years. The overall rate of severe illness cases was 4.51% from 2012 to 2023. There were significant differences in severe illness cases among different areas and years ( χ2=5.33, P=0.021; χ2=48.14, P<0.001). Enteroviruses were mainly detected (31.57%), in which Coxsackie virus was predominant (58.37%). Imaging findings showed that cerebral hemisphere damage was most common in children and adolescents with viral encephalitis (54.93%). Conclusions:From 2012 to 2023, more cases of viral encephalitis occurred in boys in Henan. Children and adolescents aged 7-13 years were the main affected group. The prevention of enteroviruses infection, especially Coxsackie virus, needs to be strengthened. Special attention should be paid to the prevention of cerebral hemisphere damage after viral encephalitis diagnosis.

Objective:To explore the function of MDM2 and its relationship with p53 at the cellular level during H 2O 2 induced oxidative damage. Methods:MLE-12 HALI cell models were established using 0.5 mmol/L H 2O 2, and were divided into three groups: normal control group, H 2O 2 injury group, H 2O 2+MDM2 overexpressed group, and H 2O 2+MDM2 shRNA group. Infection of MLE-12 cells with adenovirus vector overexpressing and silencing MDM2; Using immunoprecipitation (Co-IP) to analyze the interaction between MDM2 and p53; Western blotting was used to detect the protein expression levels of MDM2, p53, Bcl-2, Bax, and cleared caspase-3 after HALI modeling; Measure the apoptosis rate of cells in each group. Results:After transcriptome sequencing,the p53 signaling pathway closely related to HALI. Compared with the normal group, the expression of MDM2 in the H 2O 2 injury group was lower ( P<0.05); Compared with the H 2O 2 injury group, overexpression of MDM2 resulted in a decrease in the apoptosis rate of MLE-12 cells ( P<0.05), a decrease in the expression levels of p53, Bax, and cleared caspase-3 proteins, and an upregulation of MDM2 and Bcl-2 protein expression ( P<0.05). Compared with the H 2O 2 injury group, when MDM2 was silenced, the cell apoptosis rate increased ( P<0.05), and the expression levels of p53, Bax, and cleared caspase-3 proteins were upregulated, while the expression levels of MDM2 and Bcl-2 proteins decreased ( P<0.05). Co-IP experiments showed that MDM2 binds to p53 protein. Conclusions:MDM2 can exert a protective effect on HALI by inhibiting MLE-12 cell apoptosis through the p53/Bcl-2/Bax axis.

Objective:To explore with healthy adults any effect on postural control of transcranial direct current stimulation (tDCS) applied over the left dorsolateral prefrontal cortex (L-DLPFC) and the primary motor cortex (M1).Methods:Eighteen healthy adults received 3 tDCS stimulation protocols sequentially applied to either the left dorsolateral prefrontal cortex alone, the left dorsolateral prefrontal cortex and the bilateral primary motor cortex simultaneously or sham stimulation, respectively. Each intervention protocol lasted for 20 minutes with a total current intensity of less than 4mA, with a 7-day interval between the each stimulation protocol. Single-task and dual-task walking and balance tests were administered before and after each stimulation protocol, followed by statistical analysis.Results:The results of the single-task gait function testing showed that the change in step width before and after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than with sham stimulation. In the dual-task gait function tests the change in step width after single-target tDCS stimulation was (-0.511±1.072)cm, significantly better than in the other two groups.Conclusions:Stimulating only the dorsolateral prefrontal cortex can effectively regulate cognitive-motor postural control. Multi-target tDCS offers no particular advantage.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.

Objective:To investigate the risk factors for lung metastasis from differentiated thyroid cancer (DTC), predict the occurrence of lung metastasis, and diagnose lung metastasis early.Methods:From April 2013 to May 2023, 442 DTC patients (145 males, 297 females; age (41.6±13.1) years) who received 131I treatment in the First Affiliated Hospital of the Air Force Medical University were retrospectively analyzed. All patients were divided into lung metastasis group ( n=124) and non-lung metastasis group ( n=318) according to pathology or clinical, imaging and laboratory test results. Patients were randomly divided into training set ( n=309) and validation set ( n=133) at the ratio of 7∶3. The differences of clinical data between the two groups were compared by χ2 test and Mann-Whitney U test. Factors affecting lung metastasis were analyzed by multivariate logistic regression analysis. ROC curve analysis was used to evaluate the predictive ability of the model. Results:The differences of sex, primary tumor type, multifocal, extra thyroid tissue invasion, number of operations, thyroglobulin (Tg) level before 131I treatment, maximum diameter of primary lesion, lymphocyte absolute value, neutrophil absolute value and B-Raf proto-oncogene, serine/threonine kinase (BRAF) V600E mutation between the two groups were statistically significant ( χ2 values: 7.72-107.77, z values: from -6.50 to -2.44, all P<0.05). Multivariate logistic regression analysis showed that multifocal (odds ratio ( OR)=5.646, 95% CI: 1.763-18.089, P=0.004), BRAF V600E mutation ( OR=0.184, 95% CI: 0.062-0.543, P=0.002), Tg level before 131I treatment ( OR=1.015, 95% CI: 1.004-1.025, P=0.005), lymphocyte absolute value ( OR=0.395, 95% CI: 0.166-0.940, P=0.036) and maximum diameter of primary lesion ( OR=1.932, 95% CI: 1.207-3.093, P=0.006) were independent factors affecting lung metastasis. The AUCs of the training set and validation set obtained by the nomogram prognostic model were 0.899 and 0.889, respectively. Conclusion:Large primary tumor, multiple focus, non-mutated BRAF V600E gene, high Tg level before 131I treatment and low lymphocyte absolute value may be considered as risk factors for lung metastasis of DTC.
