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.

ObjectiveTaking classical herbal pair compatibility research as the entry point， this study aimed to deeply investigate the material basis and compatibility rules underlying the antidepressant effects of the traditional Chinese medicine （TCM） formula Zhizi Houpotang， and to elucidate its antidepressant mechanism， with a particular focus on its regulation of neuroinflammatory responses mediated by the NOD-like receptor protein 3 （NLRP3）/gasdermin D （GSDMD） signaling pathway and the consequent improvement of neuronal synaptic plasticity. MethodsC57BL/6J mice were randomly divided into a blank control group， a chronic unpredictable mild stress （CUMS） depression model group， a Zhizi Houpotang full-formula group （6 g·kg^-1·d^-1）， a Magnoliae Officinalis Cortex （MOC）-Aurantii Fructus Immaturus （AFI） herbal pair group （4.2 g·kg^-1·d^-1）， a Gardeniae Fructus （GF）-MOC herbal pair group （4.2 g·kg^-1·d^-1）， a GF-AFI herbal pair group （3.6 g·kg^-1·d^-1）， and a positive drug group （fluoxetine， 12 mg·kg^-1·d^-1）. Depressive-like behaviors in mice were evaluated using behavioral tests. Immunofluorescence staining was used to label and quantify the expression of the microglial marker ionized calcium-binding adaptor molecule 1 （Ibal） and the purinergic receptor P2X ligand-gated ion channel 7 （P2RX7） in the prefrontal cortex （PFC）. Enzyme-linked immunosorbent assay （ELISA） was applied to detect the levels of inflammatory cytokines interleukin-1β （IL-1β） and interleukin-18 （IL-18） in serum and PFC tissues. Western blot was employed to determine the expression of pannexin 1 （Panx1）， P2RX7， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， Caspase-1， GSDMD， postsynaptic density protein 95 （PSD95）， and the presynaptic protein Synapsin 1 in PFC tissues. Golgi staining was used to assess dendritic spine density of neurons in the PFC. ResultsCompared with the blank control group， the depression model group exhibited significant depressive-like behaviors. In addition， the immunofluorescence areas of Ibal and P2RX7 in the PFC were significantly increased （P<0.01）， the levels of IL-1β and IL-18 in serum and the PFC were significantly elevated （P<0.01）， and the protein expression levels of Panx1， P2RX7， NLRP3， ASC， Caspase-1， and GSDMD in the PFC were significantly upregulated （P<0.01）. In contrast， the protein expression levels of PSD95 and Synapsin 1 were significantly downregulated （P<0.01）， and neuronal dendritic spine density was significantly reduced （P<0.01）. Compared with the model group， the Zhizi Houpotang full-formula group and the GF-MOC herbal pair group showed significant improvement in all the above indicators （P<0.01）. The GF-AFI herbal pair group improved all the above indicators except P2RX7， Caspase-1， GSDMD， and PSD95 （P<0.05， P<0.01）. In contrast， the MOC-AFI herbal pair group showed no statistically significant improvement in any of the above indicators compared with the model group. ConclusionZhizi Houpotang and its key herbal pair， GF-MOC， can effectively ameliorate CUMS-induced depressive-like behaviors in mice. Its core antidepressant mechanism may involve inhibition of P2RX7/Panx1 signaling， thereby blocking the NLRP3/GSDMD-mediated pyroptosis pathway and significantly reducing the release of inflammatory cytokines IL-1β and IL-18. Simultaneously， it upregulates the expression of synapse-related proteins PSD95 and Synapsin 1 and increases dendritic spine density， promoting the recovery of synaptic plasticity. These results suggest that GF plays a key role in the antidepressant effects of this formula， and that the compatibility of GF with MOC may represent the principal herbal pair combination responsible for its core therapeutic action.

Objective: To investigate the prevalence of overweight and obesity among children and adolescents in Yangzhou City, and its association with screen behaviors, so as to provide scientific evidence for weight management among students. Methods: In May 2025, an electronic questionnaire survey was conducted among children and adolescents in Yangzhou City. A total of 3 722 participants were selected from grades 4 to 12 in 18 primary and secondary schools (108 classes) by using stratified cluster random sampling. The Chi square test was used to compare the differences in the detection rates of overweight and obesity among children and adolescents with 5 types of screen behaviors (watching TV, playing electronic games, scrolling short videos, screen based learning, electronic socializing) in different time groups each day (never, >0~<2 h, ≥2 h). Multivariate Logistic regression analysis was performed to examine the associations of five types of screen behaviors, presence of electronic devices in the bedroom, and screen use during meals on the weight status of children and adolescents. Results: The prevalence of overweight and obesity among children and adolescents was 37.3%. For all five types of screen behaviors, the differences in the distribution of overweight and obesity detection rates among children and adolescents across the three time spent categories were statistically significant ( χ 2=30.76- 70.78 , all P <0.01). After adjusting for confounding factors, multivariate Logistic regression analysis revealed that frequent or always using screens during meals( OR =1.63, 95％ CI =1.14~2.31), playing video games ( OR =1.28, 95% CI =1.11-1.48), browsing short videos ( OR =1.29, 95％ CI=1.09-1.54), and screen based learning ( OR =1.26, 95％ CI =1.10-1.44) were significantly associated with overweight and obesity among children and adolescents (all P <0.05). Conclusions Excessive screen use is positively correlated with the incidence of overweight and obesity in children and adolescents. Targeted interventions on screen behaviors among children and adolescents are therefore warranted.

Lung cancer is one of the most lethal cancers, and the overall survival rate of lung cancer patients is very low. With the increasing research on lung cancer, the critical role of intestinal flora in lung cancer treatment has been gradually discovered. Among the various therapeutic approaches targeting the intestinal flora, fecal microbiota transplantation (FMT) is considered as a potential strategy to treat lung cancer by interfering with the homeostasis of the intestinal flora. FMT can improve the efficacy of lung cancer treatment and attenuate the side effects associated with immunotherapy, chemotherapy, and radiotherapy by remodeling the microbial composition, modulating the metabolites, and activating immune responses. The aim of this paper is to discuss the current status and potential mechanisms of FMT in lung cancer treatment, and to provide a new strategy for regulating the intestinal flora to enhance the prevention and treatment of lung cancer.

ObjectiveTo explore the protective effect and underlying mechanism of Gegen Qinliantang on cognitive function in db/db mice with diabetic cognitive impairment （DCI）. MethodsThirty-two 8-week-old male db/db mice were randomly assigned to the model group， dapagliflozin group （1.0 mg·kg^-1·d^-1）， low-dose Gegen Qinliantang group （6.24 g·kg^-1·d^-1）， and high-dose Gegen Qinliantang group （24.96 g·kg^-1·d^-1）. Eight db/m mice served as the normal group. All mice were administered the corresponding treatment once daily by gavage for 10 consecutive weeks. Body weight and fasting blood glucose （FBG） were dynamically monitored. The Morris water maze test was used to evaluate cognitive function. Hematoxylin-eosin （HE） staining and Nissl staining were used to observe pathological changes in the hippocampus. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in hippocampal tissue. Immunofluorescence double staining was used to detect the co-expression of M1 microglial marker CD16/32 and ionized calcium-binding adapter molecule 1 （IBA1） in the hippocampus. Western blot analysis was performed to detect the protein expression of postsynaptic density protein 95 （PSD-95）， synapsin （SYN）， nuclear factor-κB p65 （NF-κB p65）， and phosphorylated NF-κB p65 （p-NF-κB p65） in the hippocampus. ResultsCompared with the normal group， the model group showed significantly increased body weight and FBG levels （P<0.01）， significantly prolonged escape latency and reduced platform crossings in the Morris water maze test （P<0.01）， disordered arrangement of hippocampal neurons， nuclear pyknosis， increased neuronal necrosis， reduced Nissl bodies， decreased expression of synaptic proteins PSD-95 and SYN （P<0.01）， increased CD16/32⁺ /IBA1⁺ positive rate， elevated levels of TNF-α and IL-1β， and an increased p-NF-κB p65/NF-κB p65 ratio （P<0.01）. Compared with the model group， the dapagliflozin group exhibited significantly reduced FBG levels at weeks 5 and 10 （P<0.05， P<0.01） and increased body weight. The high-dose Gegen Qinliantang group showed significantly reduced FBG at week 10 （P<0.05）. Escape latency was significantly reduced on days 3 and 5 of the water maze test in the dapagliflozin group and on day 5 in the high-dose Gegen Qinliantang group （P<0.05）. Platform crossings were significantly increased in both the dapagliflozin group and the high-dose Gegen Qinliantang group （P<0.05）. Hippocampal pathological damage was alleviated to varying degrees in the dapagliflozin group and the low- and high-dose Gegen Qinliantang groups， with significantly increased expression of PSD-95 and SYN （P<0.01）. Further studies revealed that both low- and high-dose Gegen Qinliantang reduced hippocampal IL-1β levels and the CD16/32⁺/IBA1⁺ positive rate of microglia， while the high-dose group also significantly reduced hippocampal TNF-α levels and the p-NF-κB p65/NF-κB p65 （P<0.05， P<0.01）. ConclusionGegen Qinliantang can improve hyperglycemia， cognitive dysfunction， and synaptic damage in DCI， inhibit M1 polarization of microglia and neuroinflammation， and its mechanism may be related to the inhibition of NF-κB activation.

BACKGROUND:Flap transplantation technique is a commonly used surgical procedure for the treatment of severe tissue defects,but postoperative flap necrosis is easily triggered by ischemia-reperfusion injury.Therefore,it is still an important research topic to improve the survival rate of transplanted flaps. OBJECTIVE:To review the pathogenesis and latest treatment progress of flap ischemia-reperfusion injury. METHODS:CNKI,WanFang Database and PubMed database were searched for relevant literature published from 2014 to 2024.The search terms used were"flap,ischemia-reperfusion injury,inflammatory response,oxidative stress,Ca2+overload,apoptosis,mesenchymal stem cells,platelet-rich plasma,signaling pathways,shock wave,pretreatment"in Chinese and English.After elimination of irrelevant literature,poor quality and obsolete literature,77 documents were finally included for review. RESULTS AND CONCLUSION:Flap ischemia/reperfusion injury may be related to pathological factors such as inflammatory response,oxidative stress response,Ca2+overload,and apoptosis,which can cause apoptosis of vascular endothelial cells,vascular damage and microcirculation disorders in the flap,and eventually lead to flap necrosis.Studies have found that mesenchymal stem cell transplantation,platelet-rich plasma,signaling pathway modulators,shock waves,and pretreatment can alleviate flap ischemia/reperfusion injuries from different aspects and to varying degrees,and reduce the necrosis rate and necrosis area of the grafted flap.Although there are many therapeutic methods for skin flap ischemia/reperfusion injury,a unified and effective therapeutic method has not yet been developed in the clinic,and the advantages and disadvantages of various therapeutic methods have not yet been compared.Most of the studies remain in the stage of animal experiments,rarely involving clinical observations.Therefore,a lot of research is required in the future to gradually move from animal experiments to the clinic in order to better serve the clinic.

Objective:To investigate the efficacy and safety of daratumumab-based regimens for the treatment of relapsed/refractory multiple myeloma (RRMM).Methods:A retrospective case series study was conducted. Thirty-seven RRMM patients treated with daratumumab-based regimens at Shanxi Bethune Hospital from January 2017 to November 2023 were selected, and their efficacy and adverse reactions were analyzed.Results:The median age [ M ( Q1, Q3)] of 37 RRMM patients was 62 (56, 68) years, the median number of previous treatment lines was 2 (1, 3.5) lines, 12 cases (32.4%) had extramedullary lesions, 12 cases (32.4%) had lactate dehydrogenase (LDH) ≥ 245 U/L, and 11 cases (29.7%) had previously received the third-line or more treatment. Among 27 patients who completed fluorescence in situ hybridization testing, 8 cases (29.6%) had high-risk cytogenetical changes. The median time from diagnosis to use of daratumumab was 23.1 (5.9, 52.0) months. The overall response rate (ORR) of 37 RRMM patients after treatment was 75.7% (28/37), with ORR of 88.0% (22/25) and 50.0% (6/12) for patients without and with extramedullary lesions, respectively, and the difference was statistically significant ( P = 0.036). The median follow-up time was 12.3 (4.6, 22.7) months, the median progression-free survival (PFS) time was 7.8 months (95% CI: 2.0- 13.7 months), and the median overall survival (OS) time was 22.4 months (95% CI: 17.5-29.5 months). The median PFS time for patients without and with extramedullary lesions was 11.8 and 4.2 months, and the median OS time was 23.5 and 8.3 months, respectively, and the differences in PFS and OS between the two were statistically significant (both P < 0.05); the median PFS time for patients with LDH ≥ 245 U/L and < 245 U/L was 6.5 and 11.9 months, and the median OS time was 30.2 and 12.1 months, respectively, and the differences in PFS and OS between the two were statistically significant (both P < 0.05). The incidence of non-hematological adverse reactions was 32.4% (12/37), with the most common being infusion-related adverse reactions (29.7%, 11/37), all of which were grade 1-2; the incidence of ≥ grade 3 hematological adverse reactions was 13.5% (5/37), with thrombocytopenia being the most common (8.1%, 3/37). Conclusions:The ORR of RRMM patients treated with daratumumab-based regimens is high, and the adverse reactions are tolerable.

Objective:To explore the diagnostic value of transcranial magnetic stimulation (TMS), transsacral magnetic root stimulation combined with sacral reflexes, external anal sphincter electromyography and pudendal nerve somatosensory evoked potentials in the assessment of neurogenic lower urinary tract dysfunction (NLUTD).Methods:Twenty-one NLUTD patients (1 with a supra-pontine lesion, 5 with a spinal cord injury, 5 with a cauda equina injury, and 10 with pelvic floor disorders) were enrolled. Needle electromyography (EMG) was used to record TMS-induced and transsacral magnetic stimulation-induced motor evoked potentials (tc-MEPs and ts-MEPs, respectively) related to the external anal sphincter (EAS). The dorsal nerve of the penis or clitoris was stimulated electrically to record the latency of the sacral reflex related to the EAS. Central motor conduction time (CMCT) and the tc/ts-MEP latency ratio were calculated to distinguish central from peripheral lesions.Results:In the one patient with a supra-pontine lesion, although the tc-MEP and ts-MEP latencies were within normal limits, the CMCT was prolonged (28.2ms) and the tc/ts-MEP ratio was large (7.4). Among the five patients with a spinal cord injury, one exhibited prolonged tc-MEP latency (50.6ms) and CMCT (47.8ms), along with a large tc/ts-MEP ratio (18.1). In the five patients with cauda equina injury and the ten with NLUTD secondary to pelvic floor disorders, CMCT was within the normal range [averaging (22.9±4.9ms) and (24.2±3.5ms), respectively], but the ts-MEP latency was prolonged [(7.1±2.1ms) and (8.6±3.7ms), respectively], and the tc/ts-MEP ratio was small [(4.4±0.9) and (4.3±1.5), respectively]. The tc/ts-MEP ratio demonstrated the best rate of abnormality detection (93.8%), with an area under the curve of 0.99, indicating good sensitivity.Conclusions:The tc/ts-MEP ratio can be useful for distinguishing central and peripheral lesions. A markedly increased tc/ts-MEP ratio may suggest central nervous system injury, whereas a decreased ratio may indicate peripheral nervous system injury.
