BackgroundCognitive function is closely related to an individual's quality of life and social functioning， with approximately 20%~35% of patients with depressive disorder experiencing some degree of cognitive impairment even after clinical symptom remission. Existing evidence suggests that tACS can improve specific cognitive domains， such as memory function， while its effects on other cognitive dimensions， such as executive functioning， attention， and information processing speed， remain unclear. ObjectiveTo explore the effects of tACS on the multidimensional cognitive functions and emotional problems of patients with depressive disorder， thus to provide references for the treatment of depressive disorder. MethodsForty-nine patients with depressive disorder who were hospitalized in the Fourth People's Hospital of Wuhu from November 2022 to October 2024 and met the diagnostic criteria for depressive disorder outlined in the Diagnostic and Statistical Manual of Mental Disorders， fifth edition （DSM-5）， were selected as study participants. Subjects were randomly divided into study group （n=23） and control group （n=26） based on Microsoft Excel. Both groups received sertraline treatment. The initial dose was 50 mg/day， which gradually titrated upward based on individual variability， drug tolerance， and therapeutic response， with a maintenance dose ranging from 100 to 200 mg/day. In addition， the study group underwent tACS therapy for 4 weeks， with 5 sessions per week， each lasting 20 minutes. The control group received sham stimulation， in which the stimulus was interrupted after the first 30 seconds. At baseline， the 4^th week， and the 12^th week of treatment， patients were assessed using the Hamilton Depression Scale-17 item （HAMD-17）， Hamilton Anxiety Scale （HAMA）， and MATRICS Consensus Cognitive Battery （MCCB）. ResultsRepeated measures analysis of variance indicated that both the time effect and the time×group interaction effect for HAMD-17 scores were statistically significant between the two groups （F=260.437， 25.309， P<0.01）. At week 12 of treatment， the HAMD-17 score in the study group was lower than that in the control group （t=4.236， P<0.01）. For HAMA scores， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=248.082， 4.506， 9.500， P<0.05 or 0.01）. At weeks 4 and 12， study group reported lower HAMA scores compared with control group （t=4.580， 2.608， P<0.05 or 0.01）. Regarding the MCCB scores for attention/vigilance， verbal learning， and overall composite， the time effect， group effect， and time×group interaction effect were all statistically significant between the two groups （F=70.331， 27.882， 51.679， 5.560， 10.948， 7.860， 8.490， 3.874， 5.025， P<0.05 or 0.01）. After intervention， the study group showed significantly higher MCCB scores for attention/vigilance， verbal learning， and overall composite at both week 4 （t=-2.149， -3.530， -2.740， P<0.05） and week 12 （t=-3.534， -3.576， -3.838， P<0.01） when compared to the control group. ConclusionThe combined tACS and sertraline therapy may demonstrate superior efficacy to pharmacotherapy alone in the short term for improving attention/vigilance， verbal learning， overall cognitive function， and anxiety symptoms in patients with depressive disorders. Based on the 12-week outcomes， the combined tACS and sertraline therapy not only sustaine its previously observed advantages in improving cognitive domains and anxiety symptoms， but also demonstrate potentially superior efficacy over monotherapy in alleviating depressive symptoms. ［Fund by Clinical Medical Research Transformation Special Project of Anhui Province （number， 202204295107020065）］

Objective:To evaluate the safety and efficacy of sequential consolidation thoracic radiotherapy after first-line chemotherapy combined with immunotherapy for extensive-stage small cell lung cancer (SCLC).Methods:A retrospective analysis of patients with extensive-stage SCLC admitted to Jiangsu Cancer Hospital from January 2019 to September 2022 was conducted. Patients who achieved effective chemotherapy combined with immunotherapy received sequential consolidation thoracic radiotherapy. The safety was evaluated according to the common terminology criteria for adverse events (CTCAE) 5.0 standard, and the overall survival (OS) and progression-free survival (PFS) were analyzed by Kaplan-Meier method.Results:A total of 33 patients were enrolled, with a median age of 66 years (range, 50-79 years). The median follow-up time was 20 months (range, 3-33 months). Fifteen patients (46%) had disease progression, and 12 patients (36%) died. The toxicities mainly included leukopenia, thrombocytopenia, radiation esophagitis, anorexia, and fatigue, etc. Six patients (18%) had grade 4 hematological toxicity, mainly leukopenia. One patient (3%) had grade 3 radiation pneumonitis, and 3 patients (9%) had grade 1-2 radiation pneumonitis. No grade 5 toxicity was observed in all patient groups. The median PFS was 12 months (95% CI=3.9-20.1). The 6-month, 1-year, and 2-year PFS rates were 78%, 49.6%, and 35.6%, respectively. The median OS was 23 months (95% CI=15.98-30.01). The 6-month, 1-year, and 2-year OS rates were 86.2%, 74.5%, and 47.2%, respectively. Conclusions:Sequential consolidation thoracic radiotherapy after first-line chemotherapy combined with immunotherapy is a safe protocol for extensive-stage SCLC. It brings survival benefits to patients by increasing PFS and OS rates.

Objective:To evaluate the safety and efficacy of tumor-treating fields (TTFields) and chemoradiation in patients with high-grade glioblastoma.Methods:Clinical data of 38 patients admitted to the Jiangsu Cancer Hospital from September 2021 to May 2023 who were diagnosed with high-grade glioblastoma (36 cases of World Health Organization grade Ⅳ and 2 cases of grade Ⅲ) were retrospectively analyzed. All patients received TTFields combined with concurrent chemoradiation after surgery. Response assessment in neuro-oncology (RANO) criteria was used to evaluate the glioma responses as tumor remission, stable or progression. Common terminology criteria for adverse events v5.0 and TTFields related skin adverse reaction (dAE) criteria were used to evaluate the adverse events. Treatment compliance was assessed by data on the NovoTTF-200A therapeutic device, calculated as a percentage of daily TTFields usage time. Survival analysis was estimated by the Kaplan-Meier method and compared by the log-rank test.Results:The median duration of treatment with TTFields in 38 patients was 20 h (rang: 2.4-22.6 h), and the median treatment compliance was 83% (range: 10%-94%). After 42 days of TTFields combined with concurrent chemoradiation, 12 patients who underwent complete tumor resection were assessed as stable according to RANO criteria. Among the 26 patients who underwent partial tumor resection, 23 (88%) were evaluated as disease remission according to RANO criteria. The 7-, 10-, 13-month progression-free survival rate was 81.0%、64.0%、49.5%, repectively. The common adverse events included grade 1 (45%) and grade 2 (8%) dAE, without grade 3-4 dAE. Typical presentations included contact dermatitis, blisters, lesions or ulcers, and abscesses. The median follow-up time was 10.0 months (range: 1.6-21.3 months). At follow-up as of July 2023, 26 of the 38 patients were stable and 12 had disease progression (8 died).Conclusion:The preliminary results show that TTFields combined with chemoradiation is effective, safe and reliable treatment for high-grade glioblastoma.

Objective:To explore the optimization of the standardized assessment tool for clinical diagnosis of Chinese developmental dyslexia (DD).Methods:A cross-sectional study was conducted from May to December 2023, in which 130 primary school children in grades 1 to 3 with clinical signs of literacy lag and positive screening results on the screening scales were recruited from the outpatient clinic of Child Health Care Medical Division, Shanghai Children′s Hospital, Shanghai Jiao Tong University School of Medicine. Chinese dyslexia screening behavior checklist for primary students (CDSBC) was used as the screening scales, and supplemented by dyslexia checklist for Chinese children. Referring to the standard procedure of the"expert advice on diagnosis and intervention of Chinese developmental dyslexia", the developmental dyslexia scale for standard mandarin (DDSSM) was used to evaluate the children′s literacy-related cognitive abilities and conduct the diagnostic assessment, and divided the children into learning backward group and the DD group. The t-test and χ2 test were used to compare the differences in the distribution of intelligence, literacy and attention deficit hyperactivity disorder between the two groups. Spearman′s correlation was used to analyze the correlation between the scores for each cognitive ability in the DDSSM and the CDSBC. Results:Of the 130 children, 90 were male, aged (8.3±1.0) years; 40 were female, aged (8.1±0.9) years. A final diagnosis of DD was made in 59 cases, of which 41 were males. There was no statistically significant difference in operational intelligence quotient (101±15 vs.100±15, t=0.53, P>0.05) and statistically significant difference in literacy of DDSSM (32±5 vs.21±4, t=11.56, P<0.001) between the learning backward group and the DD group. Eighteen cases (25.4%) of the learning backward group were children with attention deficit subtype attention deficit hyperactivity disorder (ADHD-I), and 16 cases (27.1%) in DD group, the difference in incidence between the two groups was not statistically significant ( χ2=0.05, P>0.05). There were correlations between the DDSSM (for oral vocabulary, morphological awareness and orthographic awareness) and the CDSBC total score ( r=-0.42, -0.32, -0.35, all P<0.01), but the correlations for visuospatial perception and rapid automatized naming with CDSBC total score were not statistically significant ( r=-0.09 and -0.20,both P>0.05). Conclusion:For literacy-related cognitive abilities, screening scales CDSBC are not sufficiently useful for assessment, so the introduction of standardized assessment tools DDSSM is an optimization of the clinical diagnosis of Chinese DD, which is crucial for achieving accurate diagnosis and intervention.

Objective:To investigate the expression level of UBE2C in liver cancer tissues and its effect on the proliferation and invasion of hepatocellular carcinoma cells HepG2 after UBE2C silencing.Methods:The data set of liver cancer was downloaded from the TCGA database.Ac-cording to the median expression level of UBE2C mRNA in liver cancer tissues,all liver cancer pa-tients were divided into UBE2C higher(n=169)and lower expression group(n=205),respectively.The expression level of UBE2C mRNA in liver cancer tissues and its relationship with the patients prognosis was analyzed.COX regression was used to analyze the influencing factors of the liver cancer patients prognosis.The human hepatocellular carcinoma cell lines(HepG2,Huh7 and SMMC-7721)and human nromal hepatic epithelial cell line(THLE-3)were selected,and the ex-pression level of UBE2C in the four cell lines were detected by Western blot and real-time fluores-cence quantitative PCR,respectively.The HepG2 cell line was protein and mRNA expression leves divided into control group,NC group and si-UBE2C group according to UBE2C silencing.The ef-fects of UBE2C silencing on proliferation and invasion of HepG2 cell line were analyzed.Results:The expression level of UBE2C mRNA in liver cancer tissues and adjacent normal liver tissues were 4.342(3.239,5.635)and 0.905(0.587,1.230),respectively.Compared with adjacent normal liver tissues,UBE2C mRNA levels in liver cancer tissues were significantly higher(P＜0.001).The UBE2C mRNA expression levels in liver cancer tissues and paired adjacent normal liver tissues were 4.266(3.342,5.054)and 0905(0.587,1.230),respectively.Compared with paired adjacent normal liver tissues,UBE2C mRNA expression levels in liver cancer tissues were significantly higher(P＜0.001).The median survival time of UBE2C mRNA higher and lower expression groups was 48.85 months and 69.38 months.Compared with the lower expression group,the median survival time of UBE2C mRNA higher expression group was significantly shortened(P=0.045).T staging(T3/T4)and UBE2C expression(higher expression)were independent risk factors for poor prognosis in patients with liver cancer(P＜0.05).Compared with human liver epithelial cell line THLE-3,UBE2C protein and mRNA were significantly higher expressed in human hepatocellular carcinoma cell line HepG2,Huh7 and SMMC-7721(P＜0.05).The expression level of UBE2C protein and mRNA expression was the most significant in human hepatocellular carcinoma cell line HepG2 relative to cell line Huh7 and SMMC-7721.The CCK-8 results show that the cell proliferation rate in si-UBE2C group were significantly decreased protein and mRNA expression levels compared to control group and NC group at 72 h and 96 h,and the differences were significant(P＜0.05).The number of invasive cells in control group,NC group and si-UBE2C group were(23.12±3.45),(24.33±2.83)and(10.21±1.14),respectively.Compared with control group and NC group,the number of invasive cells in si-UBE2C group was significantly decreased(P＜0.05).Conclusion:UBE2C was higher expressed in liver cancer,and can be used as a biomarker for poor prognosis of patients with liver cancer.After silencing of UBE2C gene can significantly inhibit proliferation and invasion of HepG2.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM To study the effects of Liangxue Heying Formula on vascular inflammatory injury in a rat model of thromboangiitis obliterans(TAO).METHODS The rats were randomly divided into the sham operation group,the model group and the low,medium and high dose Liangxue Heying Formula groups(2.25,4.5,9 g/kg).With the rat TAO model successfully established by injection of 0.1 mL sodium laurate(10 mg/mL)into the femoral artery of hind limbs,corresponding doses of drugs by gavage were administered upon the rats.Subsequently,the rats had their morphological changes of the affected limbs observed and assessed;their changes of blood flow in hind limbs scanned by laser Doppler flowmetry;their plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1 detected by ELISA;their histopathological changes of femoral artery and vein observed by HE staining;and their protein expressions of TNF-α,IL-6,JAK2,p-JAK2,STAT3,p-STAT3,ICAM-1 and VCAM-1 in femoral artery detected by Western blot.RESULTS Compared with the sham operation group,the model group displayed increased morphological score of the affected limb(P＜0.01);decreased blood perfusion ratio of the affected side/healthy side(P＜0.01);increased plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1(P＜0.01);more existence of thrombotic infiltration containing a larger number of inflammatory cells in femoral artery and femoral vein tissue,and increased protein expressions of TNF-α,IL-6,p-JAK2,p-STAT3,ICAM-1 and VCAM-1 in femoral artery(P＜0.01).Compared with the model group,the medium and high dose Liangxue Heying Formula groups demonstrated decreased morphological score of the affected limb(P＜0.01);increased blood perfusion ratio of the affected side/healthy side(P＜0.01);reduced infiltration of thrombus and inflammatory cells in femoral artery and femoral vein tissue,and decreased protein expressions of IL-6 and p-STAT3 in femoral artery tissue(P＜0.01).All Liangxue Heying Formula groups shared decreased plasma levels of TNF-α,IL-6,ICAM-1 and VCAM-1(P＜0.05,P＜0.01);and reduced protein expressions of TNF-α,ICAM-1,VCAM-1 and p-JAK2 in femoral artery(P＜0.01).CONCLUSION Liangxue Heying Formula can improve the systemic inflammatory state of TAO rats by inhibiting the activation of endothelial cells and reducing vascular inflammatory injury possibly due to the mechanism associated with the regulation of the JAK2/STAT3 signaling pathway.

Aim To explore the effect of γ-ray on the mRNA,protein expression levels and metabolic activity level of the key drug metabolic enzyme CYP3A1 in rat liver. Methods Wistar rats were randomly divided into control group, 24 h post-radiation group and 72 h post-radiation group. The experimental group was exposed to total body irradiation of single 6 Gy γ-ray. Blood was collected from the orbital venous plexus for blood routine examination and biochemical analysis 24 h and 72 h after irradiation, and liver tissue was prepared for quantifying expression of CYP3A1 mRNA and liver-specific microRNA (miR-122-5p) through RT-PCR. The expression level of CYP3A1 protein was analyzed by Western blot, and the metabolic activity level of CYP3A1 detected by the specific substrate midazolam combined with LC-MS method. Results Com¬pared with the control group, the weights of the rats in the radiation group significantly decreased, and the number of white blood cells was markedly reduced. Simultaneously, the activities of alanine aminotrans-ferase and alkaline phosphatase continuously descended, as well as the levels of total bilirubin and bile acid significantly increased, which indicated that the liver may be damaged after radiation. The relative expression of CYP3A1 mRNA continued to increase significantly 24 h and 72 h after irradiation. CYP3A1 protein expression and metabolic activity levels showed an obvious increasing trend 24 h after irradiation, and rose significantly 72 h after irradiation compared with the control group. At the same time, the expression of miR-122-5p in liver of rats in the 24 h and 72 h post-radiation group continued to decrease rapidly compared with the control group. Conclusions γ-ray radiation may arouse damage effect on liver, which leads to the continuous up-regulation of the mRNA and protein expression levels of the capital metabolic enzyme CYP3A1 in liver tissue, as well as the elevation of the metabolic activity level. The regulatory mechanism might be related to miR-122-5p.

Abstract Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

Objective:To analyze the clinical efficacy and prognostic factors of intracranial primary diffuse large B-cell lymphoma (DLBCL).Methods:Clinical data of 205 patients pathologically diagnosed with intracranial primary DLBCL at Sun Yat-sen University Cancer center from March 2001 to September 2020 were retrospectively analyzed. Among them, 101 patients were male and 104 female, the median age was 54 years old. Non-germinal center B cell (GCB) subtype accounted for 74.1%(126/170). A total of 177 patients received high-dose methotrexate (HD-MTX) and 91 patients received rituximab. After induction chemotherapy, 59 patients (30.4%) achieved complete response (CR), 112 patients (57.7%) achieved partial response (PR) or stable disease (SD). A total of 83 patients received consolidation or salvage radiotherapy, and only 14 patients received autologous stem cell transplantation (ASCT). The influence of pathological type, chemotherapy, rituximab treatment, radiotherapy and radiotherapy mode, ASCT and other factors on the overall survival (OS) and progression free survival (PFS) was evaluated. The survival rate was calculated by Kaplan-Meier method. Univariate prognostic analysis was performed by log-rank test. Multivariate prognostic analysis was conducted by COX model.Results:The median follow-up time was 34 months. The 5-year OS and PFS rates were 55.6% and 44.2%, respectively. GCB subtype, chemotherapy with HD-MTX, rituximab treatment, remission status after induction chemotherapy, and radiotherapy were favorable prognostic factors for OS or PFS, in which the last three were the independent prognostic factors. Consolidation radiotherapy in patients who obtained CR after induction chemotherapy did not significantly improve survival, while salvage radiotherapy in patients who achieved PR/SD after induction chemotherapy significantly improved both OS and PFS(both P<0.01). Consolidation radiotherapy showed no significant survival difference compared with consolidation ASCT. Conclusions:The non-GCB subtype of intracranial primary DLBCL is related to poor prognosis. The addition of rituximab to HD-MTX based induction chemotherapy can improve survival. Radiotherapy is still an important treatment for intracranial primary DLBCL, and there are limitations of ASCT in practical clinical application.
