Objective: To explore the association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province, so as to provide theoretical basis for the prevention of anxiety and depressive symptoms co-occurrence among adolescents. Methods: A random cluster sampling involving 8 500 first year junior high school students in 11 counties in Yunnan Province was conducted by a questionnaire survey from October to December 2022. The Depression Anxiety Stress Scale-21 (DASS-21) was applied to assess anxiety and depressive symptoms in first year junior high school students. Chi-square test was used to compare the anxiety-depression co-occurrence symptoms of first year junior high school students with different demographic characteristics. The association between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms of adolescents was analyzed by binary Logistic regression models. Results: The detection rate of co-occurrence of anxiety and depression symptoms among first year junior high school students in Yunnan Province was 26.92%. After controlling for demographic variables and other confounders, takeout fast foods and sugar sweetened beverage consumption( OR=1.50, 95%CI =1.27-1.77) was associated with anxiety-depression co-occurrence symptoms among first year junior high school students in Yunnan Province ( P <0.01). Stratified analysis showed that both Han ( OR=1.37, 95%CI =1.07-1.77) and ethnic minorities ( OR=1.60, 95%CI =1.29-2.00) exhibited statistically significant associations between takeout fast foods and sugar sweetened beverage consumption with co-occurrence of anxiety and depressive symptoms(both P <0.05). Conclusions Takeout fast foods and sugar sweetened beverage consumption increases the risk of co-occurrence of anxiety and depressive symptoms among first year junior high school students in Yunnan Province. It is recommended to strengthen guidance on the consumption of such products among junior high school students to prevent co-occurrence of anxiety and depressive symptoms.

Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

Objective: To analyze the demographic characteristics of patients with red blood cell transfusion reactions, the usage of red blood cell preparations, and the differences in the composition ratio of adverse reactions based on multi-center data from the Haemovigilance Network, in order to reveal the clinical characteristics of red blood cell transfusion and its underlying issues. Methods: Clinical data of patients who experienced transfusion reactions after red blood cell transfusion in the Haemovigilance Network from 2018 to 2023 were collected. The demographic characteristics of patients who experienced transfusion reactions with different types of red blood cell preparations, the utilization of these preparations, and the differences of the composition ratios of transfusion reactions were analyzed. Count data were expressed as numbers (n) or percentages (%), and comparisons between groups were performed using the Chi-square test. Results: Red blood cell transfusion reactions were more common in females (53.56%), with the majority of patients aged 50-69 years (35.54%). The Han polulation accounted for the vast majority of patients (92.77%), and patients in the hematology and obstetrics/gynecology departments had a relatively high proportion of transfusion reactions (13.26% and 14.26%, respectively). Leukocyte-reduced red blood cells and suspended red blood cells were the most common types of transfusion reactions reported among red blood cell preparations. Allergic reactions and non-hemolytic febrile reactions were the most common transfusion reactions, and there were significant differences in the composition ratios of allergic reactions (χ =869.89, P<0.05) and non-hemolytic febrile reactions (χ =812.75, P<0.05) across various types of red blood cell preparations. Conclusion: There are differences in the demographic characteristics and composition ratio of transfusion reactions among different red blood cell preparations. The management of red blood cell transfusion reactions should be tailored to patient characteristics and conditions, and the selection and use of blood products should be optimized to reduce or avoid the occurrence of transfusion reactions, such as considering the use of washed red blood cells for patients with a history of transfusion allergies or those prone to allergies.

Objective To explore the protective effect of hydroalcoholic extract of Portulaca oleracea L.(POHA)on ulcerative colitis(UC)and bone loss in mice.Methods The C57BL/6 mice were treated with dextran sulfate sodium(DSS)to establish UC model.A total of 50 mice were randomly assigned to including control group,DSS group,mesalazine(MS)group,low dose of POHA(POHAL)group,or high dose of POHA(POHAH)group.The control group freely drank drinking water,while the DSS,MS,POHAL and POHAH groups drank drinking water containing DSS for 8 weeks.Since the 2nd week,the control group and DSS group were given normal saline by gavage.The MS group was given MS(100 mg/kg)by gavage.The POHAL group and POHAH group were given POHA(1 000 mg/kg and 2 000 mg/kg)by gavage,respectively.Body weight and disease activity index(DAI)were recorded and calculated every 2 d.On the 56th day,the colon weight index,liver index,and spleen index were calculated,and the histological changes of colon were observed.Serum levels of bone metabolism markers and microstructure parameters of femur were detected.Results Compared with the control group,the DSS group showed significantly increased DAI score,colon weight index,liver index,and spleen index(all P＜0.01).The DSS group exhibited significant pathological damage in colon tissues and significantly increased serum levels of osteocalcin,C-terminal peptide of collagen type Ⅰ,and tartrate-resistant acid phosphatase 5b(P＜0.01).The bone loss was significant in the DSS group,manifested by markedly decreased bone mineral density(BMD),bone tissue volume to tissue volume ratio(BV/TV),trabecular bone number(Tb.N),and trabecular bone thickness(Tb.Th),and markedly increased bone surface to bone volume ratio(BS/BV)and trabecular bone separation(Tb.Sp)(P＜0.05 or P＜0.01).Compared with the DSS group,the BMD,BV/TV,Tb.N and Tb.Th of the femur in the MS group and POHAH group of mice were all increased(P＜0.05 or P＜0.01),the BS/BV all decreased(P＜0.05 or P＜0.01),and the Tb.Sp all decreased without significant differences(all P＞0.05).The above bone microstructure parameters in the POHAL group showed no significant differences compared with those in the DSS group(all P＞0.05).Conclusion POHA has protective effect on DSS-induced UC and bone loss,and the mechanism may be related to the inhibition of hyperactive bone metabolism.

Objective The aim of this study was to explore the effects of changes in the estrogen receptor alpha 36(ER-α36)expression on the proliferation and membrane-initiated estrogen signaling in glioblastoma U251 cells.Methods The expression and localization of ER-α36 and EGFR glioblastoma U87 cells and U251 cells were determined by immunofluorescence,qRT-PCR and Western blot.The effect of upregulating ER-α 36 on U251 cell proliferation and estrogen signaling pathway activity by low con-centrations of 100 pmol/L icariin isomer(SNG162)was detected by MTT assay and Western blot.Results ER-α36 and EGFR were co-expressed in the cell membrane of glioblastoma.Compared with DMSO(control group),the expression ER-α36(P<0.01)and EG-FR increased in U251 cells treated with SNG162(P<0.05);Further experments also found that low concentrations of SNG162 in-creased the expression of cycle related proteins-cyclin D1,cyclin B,cyclin E and CDK4(P<0.01),and enhanced the proliferative a-bility of U251 cells(P<0.05).Conclusion The low concentration of SNG162 upregulates the expression of ER-α36,activates the estrogen-mediated ERK1/2 MAPK,p38 MAPK,and EGFR/Src signaling pathways,promotes glioblastoma proliferation,and activates the membrane initialized estrogen signaling pathway.

Objective:To explore the expression and mechanism of lncRNA MALAT1 in negative sputum for tuberculous bac-terium.Methods:Expression of lncRNA MALAT1 in peripheral blood mononuclear cells(PBMC)of patients with positive sputum bacteria(Positive group)and negative sputum bacteria(Negative group)and healthy volunteers(HC group)was detected by RT-PCR.ELISA was used to detect expression levels of TNF-α,IL-1β and IL-6 in plasma.Expression of lncRNA MALAT1 in mice macro-phages RAW264.7 was silenced by siRNA interference,and RAW264.7 cells were infected with mycobacterium tuberculosis(MTB)H37Rv.Cells were divided into four groups:Control group,Control+MTB group,MTB+si-NC group and MTB+si-MALAT1 group.Proliferation activity of RAW264.7 cells in each group was detected by CCK-8 method.The number of MTB in each group was detected by CFU.Expressions of TNF-α,IL-1β and IL-6 in supernatant of RAW264.7 cells were detected by ELISA.Results:Compared with HC group,expressions of lncRNA MALAT1 in PBMC,and TNF-α,IL-1β and IL-6 in plasma were significantly increased in Positive group and Negative group(P<0.01).Compared with Control group,expression level of lncRNA MALAT1,proliferation activity,CFU value,and concentrations of TNF-α,IL-1β and IL-6 in supernatant of Control+MTB group,MTB+si-NC group and MTB+si-MALAT1 group were significantly increased(P<0.05).Compared with MTB+si-NC group,the above detection indexes in MTB+si-MALAT1 group were significantly decreased(P<0.05),while there was no significant difference in Control+MTB group(P>0.05).Conclusion:The significantly increased expression of MALAT1 in patients with negative sputum for tuberculous bacterium is positively correlated with expression of plasma inflammatory factors,while the silence of MALAT1 expression can reduce MTB induced inflammatory response by inhibiting the proliferation and phagocytosis of MTB infected macrophages.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.
