This paper aims to study the effect of Ziziphi Spinosae Semen extracts on chronic unpredictable mild stress(CUMS)-induced depression-like and insomnia behavior models of mice. The CUMS-induced depression-like and insomnia behavior model of mice was established by CUMS treatment for three weeks. The mice were randomly divided into control group, model group, positive drug diazepam group(2 mg·kg~(-1)), as well as low-dose group(1.95 g·kg~(-1)), medium-dose group(3.9 g·kg~(-1)), and high-dose group(7.8 g·kg~(-1)) of Ziziphi Spinosae Semen extracts, with 18 mice in each group. On the 15th day of modeling, the drug was administered intragastrically once a day for one week. Then, the pentobarbital sodium cooperative righting experiment, open field experiment, and elevated plus maze experiment were carried out, respectively. The contents of neurotransmitters 5-hydroxytryptamine(5-HT) and 5-hydroxyindoleacetic acid(5-HIAA) in serum and thalamus of mice, as well as the levels of corticotropin releasing hormone(CRH), adrenocorticotropic hormone(ACTH), and corticosterone(CORT) in serum, were determined by enzyme-linked immunosorbent assay(ELISA). The neuron damage in the hippocampus of mice was observed by hematoxylin-eosin(HE) staining and Nissl staining. Western blot was used to detect the expressions of tryptophan hydroxylase 2(TPH2), serotonin transporter(SERT), monoamine oxidase A(MAOA), five prime repressors under dual repression binding protein 1(Freud1), synaptic plasticity-related proteins [cellular gene FOS(C-FOS), postsynaptic density protein 95(PSD95), synapsin 1(SYN1), and activity-regulated cytoskeleton-associated gene(ARC)], blood-brain barrier(BBB) permeability-related proteins [zonula occludens 1(ZO-1), occludin, and claudin 1], inflammatory factors [NOD-, LRR-and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), gasdermin D(GSDMD), caspase-3, and caspase-8], and antioxidant factors [nuclear factor erythroid 2-related factor 2(NRF2) and heme oxygenase 1(HO1)] in thalamic tissue of mice. The results indicated that compared with that in the model group, the sleep latency was significantly shortened, and the sleep duration was significantly prolonged in each dose group of Ziziphi Spinosae Semen extracts. The number of visits to the central area of the open field and the distance and time of visits were significantly increased in each dose group of Ziziphi Spinosae Semen extracts. In addition, the proportion of distance and time of entering the open arm area of the elevated plus maze was significantly increased in each dose group of Ziziphi Spinosae Semen extracts. The contents of 5-HT and 5-HIAA in serum and thalamus of mice increased to varying degrees in each dose group of Ziziphi Spinosae Semen extracts; the contents of CRH, ACTH, and CORT in serum of mice were significantly decreased. The protein expression of TPH2 was significantly increased. The protein expression of MAOA, SERT, and Freud1 was significantly decreased. Ziziphi Spinosae Semen extracts could also significantly reduce the protein expression of C-FOS but significantly increase the protein expression of PSD95, ARC, and SYN1. They could reduce the pathological damage of the hippocampus in mice and significantly increase the protein expression of ZO-1, occluding, and claudin 1. The protein expression of NLRP3, GSDMD, ASC, caspase-3, and caspase-8 in the thalamic tissue of mice was significantly decreased, and the protein expression of HO1 and NRF2 was significantly increased. In conclusion, Ziziphi Spinosae Semen extracts could effectively improve sleep disorders and depression-like behaviors in CUMS-induced model mice, which may be related to regulating the 5-HT anabolism process and hypothalamic-pituitary-adrenal(HPA) axis-related hormone levels, reducing pathological damage in the hippocampus, improving synaptic plasticity, repairing BBB integrity, and alleviating inflammatory response and oxidative stress damage.

Bisphenol A is a common environmental factor and endocrine disruptor that exerts a negative impact on male reproductive ability. By exploring bisphenol A-induced testicular cell death using the Institute of Cancer Research (ICR) mouse model, we found that a ferroptosis phenomenon may exist. Mice were divided into six groups and administered different doses of bisphenol A via intragastric gavage once daily for 45 consecutive days. Serum was then collected to determine the levels of superoxide dismutase and malondialdehyde. Epididymal sperm was also collected for semen analysis, and testicular tissue was collected for ferritin content determination, electron microscope observation of mitochondrial morphology, immunohistochemistry, real-time quantitative polymerase chain reaction, and western blot analysis. Exposure to bisphenol A was found to decrease sperm quality and cause oxidative damage, iron accumulation, and mitochondrial damage in the testes of mice. In addition, bisphenol A was confirmed to affect the expression of the ferroptosis-related genes, glutathione peroxidase 4 (GPX4), ferritin heavy chain 1 (FTH1), cyclooxygenase 2 (COX2), and acyl-CoA synthetase 4 (ACSL4) in mouse testicular tissues. Accordingly, we speculate that bisphenol A induces oxidative stress, which leads to the ferroptosis of testicular cells. Overall, the inhibition of ferroptosis may be a potential strategy to reduce male reproductive toxicity caused by bisphenol A.

Objective: To explore the correlation between the attachment type of lateral pterygoid muscle (LPM) and the position of temporomandibular joint (TMJ) disc in patients with temporomandibular disorders (TMD) by using wireless amplified magnetic resonance imaging detector (WAND) coupled with conventional head and neck joint coil for high resolution imaging of TMJ. Methods: Eighty-five patients with TMD diagnosed by oral and maxillofacial surgeons of Guizhou Provincial People's Hospital from October 2019 to January 2022 were collected. A total of 160 TMJ were included. There were 16 males and 69 females, aged (32.7±14.2) years. All patients were scanned with open, closed oblique sagittal and coronal WAND coupled head and neck coils with bilateral TMJ. Based on TMJ and LPM high resolution imaging, to explore the correlation between LPM attachment types and the position of TMJ disc in TMD patients, and to evaluate the potential clinical value of LPM attachment types in TMD patients. χ² test and Pearson correlation analysis were used to evaluate the correlation between LPM attachment type and TMJ disc location. Results: There were three types of LPM attachment: type Ⅰ in 51 cases [31.9% (51/160)], type Ⅱ in 77 cases [48.1% (77/160)] and type Ⅲ in 32 cases [20.0% (32/160)]. There was a significant correlation between the type of LPM attachment and the position of articular disc (χ²=28.20, P=0.002, r=0.776). There was no statistical significance between the type of LPM attachment and the reversible displacement of articular disc (χ²=0.24, P=0.887, r=0.825). Conclusions: There is a correlation between the attachment type of LPM and the position of the disc in TMD patients. WNAD coupled with conventional head and neck joint coil TMJ high resolution scan can provide reliable imaging evidence for TMD patients in evaluating the type of LPM attachment and the location of disc.

Deficiencies in the clearance of peripheral amyloid β (Aβ) play a crucial role in the progression of Alzheimer's disease (AD). Previous studies have shown that the ability of blood monocytes to phagocytose Aβ is decreased in AD. However, the exact mechanism of Aβ clearance dysfunction in AD monocytes remains unclear. In the present study, we found that blood monocytes in AD mice exhibited decreases in energy metabolism, which was accompanied by cellular senescence, a senescence-associated secretory phenotype, and dysfunctional phagocytosis of Aβ. Improving energy metabolism rejuvenated monocytes and enhanced their ability to phagocytose Aβ in vivo and in vitro. Moreover, enhancing blood monocyte Aβ phagocytosis by improving energy metabolism alleviated brain Aβ deposition and neuroinflammation and eventually improved cognitive function in AD mice. This study reveals a new mechanism of impaired Aβ phagocytosis in monocytes and provides evidence that restoring their energy metabolism may be a novel therapeutic strategy for AD.

Deficits in the clearance of amyloid β protein (Aβ) by the peripheral system play a critical role in the pathogenesis of sporadic Alzheimer's disease (AD). Impaired uptake of Aβ by dysfunctional monocytes is deemed to be one of the major mechanisms underlying deficient peripheral Aβ clearance in AD. In the current study, flow cytometry and biochemical and behavioral techniques were applied to investigate the effects of polysaccharide krestin (PSK) on AD-related pathology in vitro and in vivo. We found that PSK, widely used in therapy for various cancers, has the potential to enhance Aβ uptake and intracellular processing by human monocytes in vitro. After administration of PSK by intraperitoneal injection, APP/PS1 mice performed better in behavioral tests, along with reduced Aβ deposition, neuroinflammation, neuronal loss, and tau hyperphosphorylation. These results suggest that PSK holds promise as a preventive agent for AD by strengthening the Aβ clearance by blood monocytes and alleviating AD-like pathology.

Objective:To explore the effects of Huatan Tongluo Decoction （HTTLD） on the morphology and function of brain tissues and intestine in rats with cerebral ischemia/reperfusion based on the gut-brain axis. Method:Sixty SPF male rats were randomly divided into a sham operation group， a model group， high- （28.66 g·kg^-1）， medium- （14.33 g·kg^-1）， and low-dose （7.16 g·kg^-1） HTTLD groups， and an edaravone （4 g·kg^-1）+Clostridium butyricum （5.0×10⁸ cfu·mL^-1） group. The model was established by focal cerebral ischemia/reperfusion in rats. The drugs were administered by gavage. The brain tissue injury was determined by neurological deficit score and 2，3，5-triphenyl tetrazolium chloride （TTC） staining. The effect of cerebral ischemia/reperfusion on intestinal motility was assessed by the propulsion rate of small intestine. The intestinal mucosal cell damage was evaluated by the pathomorphological examination of the duodenal mucosa. Enzyme-linked immunosorbent assay （ELISA） was used to determine the content of D-lactate （D-LAC）， diamine oxidase （DAO）， and bacterial endotoxin （lipopolysaccharide， LPS） in serum. Western blot was used to detect the expression of Occludin， Claudin-5， and zonula occludens 1 （ZO-1） in the duodenum. Result:After cerebral ischemia/reperfusion， rats developed neurological deficit symptoms. The neurological deficit score in the model group was higher than that in the sham operation group （P<0.01）. Compared with the model group， the high- and medium-dose HTTLD groups could relieve the symptoms of neurological deficits and lower neurological deficit scores （P<0.01）. The results of TTC staining showed that the model group presented obvious infarcts in brain tissues compared with the sham operation group （P<0.01）. The cerebral infarction volumes of HTTLD groups were reduced compared with that in the model group （P<0.01）， especially the high-dose HTTLD group， and the effect was dose-dependent. Furthermore， the propulsion rate of small intestine in the model group was significantly reduced compared with that in the sham operation group （P<0.01）. Compared with the model group， HTTLD groups could increase propulsion rates of small intestine （P<0.01）， especially the high-dose HTTLD group， and the effect was dose-dependent. After cerebral ischemia/reperfusion， obvious duodenal mucosal damage could be observed， which was relieved after the administration of HTTLD. Western blot results showed that the protein expression of ZO-1， Occludin， and Claudin-5 in the model group was reduced compared with that in the sham operation group （P<0.01）. Compared with the model group， the HTTLD groups could up-regulate the expression of ZO-1， Occludin， and Claudin-5 to varying degrees （P<0.05， P<0.01）， especially the high-dose HTTLD group. ELISA showed that the serum D-LAC， DAO， and LPS of the model group were elevated compared with those in the sham operation group （P<0.01）. Compared with the model group， the HTTLD groups showed reduced D-LAC and DAO （P<0.05， P<0.01）， and the medium- and high-dose HTTLD groups showed reduced LPS （P<0.05， P<0.01）， especially the high-dose HTTLD group. Conclusion:After cerebral ischemia/reperfusion， the rats showed damaged brain tissues， neurological dysfunction， intestinal mucosal injury， weakened intestinal motility， and destroyed the intestinal mucosal barrier. HTTLD can protect against brain-gut axis injury after cerebral ischemia/reperfusion by reducing the damage on brain tissues and gastrointestinal mucosa， relieving the symptoms of neurological deficits， promoting gastrointestinal motility， improving intestinal barrier function， and reducing the release of intestinal bacterial metabolites or poisons.

ObjectiveTo explore the efficacy， safety and influencing factors of different treatment methods for epilepsy caused by cerebral cavernous malformations. MethodsWe retrospectively enrolled 71 patients with cerebral cavernous malformation with epilepsy as the main manifestation， who were divided into a drug-only group of 42 patients and a surgery combined with drug therapy group （surgery group） of 29 patients. The effects of both treatments were analyzed. ResultsComparison of the efficacy between the drug group and the surgery group showed that 32（76.2%） were effective in the former while 22（75.9%） were effective in the latter； there was no statistical difference between the two groups （P>0.05） However， a subgroup analysis of the number of lesions found that among patients with multiple lesions， 3 （75.0%） were effective in the drug group， as compared with 0 （0%） in the surgical group， and the effective rate of the drug group was higher than that of the surgical group. Among patients with a single lesion， the effective rate was higher in the surgical group than that in drug group with statistical significance ［22（95.7%） vs. 28（73.7%）， P<0.05］. There was no significant difference between the severity of EEG and the treatment effect （P>0.05）. ConclusionsEffectiveness of Drug therapy and surgical treatment of spongiform plasma malformations caused by epilepsy was similar， but surgical treatment may have postoperative complications and affect the prognosis. Patients with epilepsy caused by a single cavernous vascular malformation are recommended to be treated with surgery， while patients with epilepsy caused by multiple cavernous vascular malformations should be treated with caution.
