Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

Objective: To systematically review the development and changes in mental health policies within the National Outline for Children s Development in China from 1992 to 2030, providing a reference basis for future formulation of mental health policies among children and adolescent in China. Methods: Based on the four editions of the National Outline for Children s Development in China across different periods from 1992 to 2030, word frequency analysis was used to reveal shifts in policy priorities, and an internationally recognized framework for adolescent health policy analysis was applied to conduct a textual review. Results: Word frequency analysis revealed that the term "psychological" appeared 6 times in the National Outline for Children s Development in China (2001-2010) but increased to 20 times in the National Outline for Children s Development in China (2021-2030) (abbreviated as the National Outline of 2021), while the term "health" rose from 4 times in the National Outline for Children s Development Plan in China in the 1990s to 68 times in the National Outline of 2021. The scope of mental health policy interventions expanded to encompass five key areas:health, safety, education, welfare and legal protection. Textual analysis highlighted that the policies of the National Outline for Children s Development in China were demand driven, prioritized vulnerable groups and continuously broadened their coverage, emphasizing sustainability and appropriateness, and monitoring/evaluation mechanisms. By 2023, 42.3% of primary schools and 64.8% of secondary schools employed full time mental health education teachers. However, the National Outline for Children s Development in China lacked direct evidence of children and adolescents participation in policy formulation, and publicly available mental health data disaggregated by age and gender remained limited. Conclusion Mental health policies of children and adolescents in China have evolved from nonexistence to gradual refinement, yet institutionalized channels for youth involvement in policy development and evaluation remain insufficient, and transparency in age and gender specific mental health data needs improvement.

Objective To clarify the expression and distribution of brain⁃derived neurotrophic factor (BDNF) in the cerebrum of plateau yaks and cattle, and to explore the relationship between BDNF function and the adaptability of altitude hypoxia. Methods Five yaks and five cattles were selected.The content and distribution of BDNF in frontal lobe, temporal lobe, parietal lobe, occipital lobe, cerebrum white matter and hippocampus of yak and cattle were analyzed by Real⁃time PCR, Western blotting and Immunohistochemistry. Results Real⁃time PCR result showed that BDNF mRNA expression in the cerebrum of yaks and cattles was highest in temporal cortex, followed by hippocampus, parietal cortex, occipital cortex and frontal cortex, and lowest in white matter. Western blotting results showed that the content of BDNF protein in the cerebrum of yaks was the highest in temporal cortex,followed by hippocampus. The content of BDNF protein in other tissues was parietal cortex, frontal cortex and cerebrum white matter, and the content of BDNF protein was the lowest in occipital cortex. The content of BDNF protein intlecerebrum of cattles was the highest in the temporal cortex, followed by the hippocampus. The content of BDNF protein in other tissues was parietal cortex, occipital cortex and frontal cortex in descending order, and the protein content in cerebrum white matter was the lowest. Immunohistochemical results showed that the positive expression of BDNF protein in the cerebrum of yaks and cattles was basically similar, mainly distributed in the granulosa cells and glial cells in the frontal cortex, temporal cortex, parietal cortex and occipital cortex, glial cells in cerebrum white matter, pyramidal cell layer and polyform cell layer in the hippocampus. There was the small amount of distribution in Martinotti cells and the molecular layer of hippocampus in the cerebral cortex. Conclusion BDNF mRNA and protein are distributed and expressed in different brain regions of yaks and cattles, but the expression level different, which is speculated to be closely related to the specific functions of different cerebrum regions. The expression level of the cerebrum of yak is higher than that of cattle except occipital cortex, suggesting that it is related to the altitude hypoxic environment. BDNF may play an important role in enhancing hypoxic tolerance and protecting internal environmental homeostasis in the process of animal adaptation to hypoxic environment.

BACKGROUND:It was found that moxibustion can inhibit the inflammatory factors in the serum of rats with cerebral ischemia/reperfusion injury,resist oxidative stress,inhibit cell apoptosis,and effectively reduce cerebral ischemia/reperfusion injury. OBJECTIVE:To observe the effects of different moxibustion intervention time on the expression levels of nucleotide binding oligomerization domain-like protein 3 inflammasome(NLRP3),cysteine aspartase(caspase-1),apoptosis-related speck-like protein,exfoliatin-D protein,interleukin-1β and interleukin-18 in rats with cerebral ischemia/reperfusion injury,and to explore its action mechanism. METHODS:SD rats were randomly divided into sham operation group(n=9)and operation group(n=36).The model of focal cerebral ischemia/reperfusion injury was established by middle cerebral artery occlusion in the operation group.After successful modeling,the rats in the operation group were further divided into model group,moxibustion 10-minute group,moxibustion 15-minute group and moxibustion 30-minute group,with 9 rats in each group.Rats in the moxibustion 10-minute,15-minute and 30-minute groups were given moxibustion at"Baihui,Dazhui and Zusanli",respectively,once a day for a total of 7 days.The neurological deficits of rats were evaluated by LONGA method.The cerebral infarction was observed by 2,3,5-triphenyltetrazolium chloride staining.The pathological changes of brain tissue were observed by hematoxylin-eosin staining.The contents of interleukin-1β and interleukin-18 in serum of rats in each group were detected by ELISA.Immunohistochemistry and western blot assay were used to detect the expression levels of NLRP3,caspase-1,apoptosis-related spot-like protein and gasdermin D in the ischemic cortex of rats in each group. RESULTS AND CONCLUSION:Compared with the sham operation group,the neurological deficit score of the model group was significantly increased(P<0.01).Compared with the model group,the neurological deficit score of the moxibustion groups was significantly reduced(P<0.01).Compared with the sham operation group,the infarct volume of the model group was significantly increased(P<0.01).Compared with the model group,the infarct volume of the moxibustion groups was significantly reduced(P<0.01);the infarct volume of the rats was smallest in the moxibustion 30-minute group(P<0.05).Compared with the model group,the contents of inflammatory factors interleukin-1β and interleukin-18 in the serum of rats in the moxibustion groups were decreased(P<0.01).Compared with the moxibustion 10-minute group,the contents of inflammatory factors in the serum of rats in the moxibustion 30-minute group were significantly decreased(P<0.05).Compared with the model group,the expression of NLRP3,apoptosis-related spot-like protein,Caspase-1 and gasdermin D protein in the ischemic cortex of the moxibustion groups was significantly decreased(P<0.01).Compared with the moxibustion 10-minute and 15-minute groups,the expression of protein in the moxibustion 30-minute group was significantly decreased(P<0.05).It is concluded that moxibustion at Baihui,Dazhui and Zusanli can reduce cerebral ischemia/reperfusion injury,among which moxibustion for 30 minutes has the best effect,and its mechanism may be related to the inhibition of pyroptosis mediated by NLRP3/Caspase-1 pathway.

Objective To explore the prognostic value and immune infiltration landscape of anoikis-related long noncoding RNAs (arlncRNAs) in lung adenocarcinoma. Methods RNA-seq and clinical data of lung adenocarcinoma were downloaded from the TCGA database, and anoikis-related genes were obtained from the GeneCards and Harmonizome databases. Coexpression, differential, and WGCNA analyses were performed to screen differentially expressed arlncRNAs closely related to the occurrence of lung adenocarcinoma. A prognostic risk model was then constructed based on the arlncRNAs, and its predictive efficacy was further validated. Finally, consensus clustering was used to identify the molecular subtypes associated with anoikis in lung adenocarcinoma. Results Seven prognostic arlncRNAs were identified, and the prognostic risk models established based on them had AUC values of ROC curves greater than 0.7. Survival and immune infiltration analyses revealed that low-risk patients had high overall survival and immune infiltration, implying that they experienced good immune treatment effects. Drug sensitivity analysis showed that the high-risk patients were more sensitive to commonly used chemotherapeutic agents than the low-risk patients. According to the expression of model genes, subtypes C1 and C2 were identified through consensus clustering, and C1 showed a good prognosis. Conclusion The prognostic risk model based on the seven arlncRNAs can effectively predict the prognosis of lung adenocarcinoma patients. The results of immune-related and drug sensitivity analyses provide a reference for the precise individualized treatment of patients with lung adenocarcinoma.

Objective:To investigate the diagnosis, treatment and prognosis of ovarian yolk sac tumor (OYST).Methods:The clinicopathological data and follow-up data of 12 patients with OYST admitted to the Affiliated Hospital of Qingdao University from January 2013 to December 2020 were retrospectively analyzed, and the diagnosis, treatment and prognosis of OYST patients were summarized.Results:(1) The age of 12 patients with OYST ranged from 11 to 37 years, with a median age of 20 years. At the first visit, all 12 patients had pelvic masses. Reasons for seeing a doctor: 6 cases of abdominal distension and abdominal pain, 4 cases of mass in the lower abdomen, 1 case of vaginal bleeding, and 1 case of appendicitis. International Federation of Obstetrics and Gynecology (FIGO) 2014 staging: 4 cases in stage Ⅰa, 2 cases in stage Ⅰc, 1 case in stage Ⅱc, 4 cases in stage Ⅲc, and 1 case in stage Ⅳb. (2) All 12 patients were examined by color Doppler ultrasound before operation, among which 10 cases showed unilateral adnexal masses and 2 cases bilateral adnexal masses. The median maximum diameter of tumor was 16.5 cm (range: 6.0-28.0 cm). The preoperative levels of alpha fetoprotein (AFP) in 12 patients (all >1 210 μg/L) were significantly higher than normal (<25 μg/L). Among the 11 patients with cancer antigen 125 (CA 125) detection results, 9 patients showed elevated serum CA 125 levels. (3) Among the 12 patients, 8 young infertile patients who needed to preserve their reproductive function underwent appendectomy, 3 infertile patients underwent staged surgery for ovarian malignant germ cell tumor, and only one bilateral lesion and infertile patient underwent unsatisfactory staged surgery for ovarian malignant germ cell tumor. Of the 12 patients, 11 patients were given combined chemotherapy regimen of bleomycin, cisplatin, and etoposide (BEP) after operation. One patient without chemotherapy developed metastasis 3 months after operation, and was given BEP chemotherapy, and her condition was controlled. (4) The deadline for follow-up was December 31st, 2022, and the median follow-up time was 60 months (range: 25-115 months). All the 12 patients survived without tumor during the follow-up period, and the median disease-free survival time was 84.5 months (range: 25-115 months). Conclusions:OYST mostly occurs in children and young women. Color Doppler ultrasound examination and serum AFP and CA 125 detection have diagnostic value for OYST. Surgical treatment after diagnosis of OYST includes surgery to preserve reproductive function and timely and standardized chemotherapy after operation. The prognosis of patients is good regardless of stage.

Objective To analyze the morphology of the pterygoid hamulus and its relationship with adjacent tissues on CBCT ima-ges,establish reference data of the anatomical structure of the pterygoid hamulus in the adult population,in order to provide a basis for clinical assisted diagnosis and treatment of pterygoid hamulus syndrome and obstructive sleep apnea hypopnea syndrome.Methods A total of 151 patients with CBCT images who met the inclusion criteria were collected from August 2020 to December 2023 in the Depart-ment of Stomatology at the Second Traditional Chinese Medicine Hospital of Jiangsu Province.The CBCT images were reconstructed u-sing the maximum intensity projection(MIP)and volume rendering(VR)modes of cone-beam CT.The morphology,length,width,vertical height,abduction angle,mucosal thickness,distance from the pterygoid hamulus to the midline of the palate,and distance from the pterygoid hamulus to the greater palatine foramen were observed and statistically analyzed in 302 bilateral cases.The differ-ences in the morphology of the pterygoid hamulus and its adjacent tissues were analyzed in different places,genders and age groups.Results The apex of the pterygoid hamulus faced inward on 6 sides and outward on 296 sides.The apex of the pterygoid hamulus was sharp on 46 sides and blunt on 256 sides.The pterygoid hamulus showed no statistically significant differences in various parameters be-tween the left and right sides,except for the width.In males,the length,width,height,distance from the pterygoid hamulus to the mid-palatal suture,and mucosal thickness on the surface of the hamulus were all greater than those in females,demonstrating statisti-cally significant differences.Females also exhibited a larger outward angle of the pterygoid hamulus than males,which was statistically significant.Moreover,with the increase of age,the length and height of the pterygoid hamulus initially increased and then decreased,exhibiting statistically significant differences.Conclusion CBCT has the advantages of low radiation dosage,convenient operation,clear imaging,stable measurement data,and clear images in the examination of pterygoid hamulus.It helps in the diagnosis and treat-ment of pterygoid hamulus-related diseases in a clinical setting.

Objective:To investigate the criteria for two-way referral of diabetes in China through systematic review.Methods:According to inclusion and exclusion criteria, articles on two-way referral criteria for diabetes in China were retrieved from databases of PubMed, Embase, Cochrane Library, CNKI and Wanfang from inception to July 15, 2023. The data were extracted, by author′s name, publish year, criteria for rupwards and downwards referral, sample size, study region, study type and main conclusions.Results:A total of 702 relavent articles were retrieved, and 15 of which were included in the analysis. Blood glucose levels were the basic criteria for two-way referral, The criteria for upward referral included fasting blood glucose, 2-h postpradial blood glucose, glycosylated hemoglobin and random blood glucose, but there were variations in measuement values. The criteria for downward referral included fasting blood glucose, 2-h postpradial blood glucose, glycosylated hemoglobin, with the variation in fasting blood glucose. Lipids and blood pressure were also included in the referral criteria in later literature, with the variation of blood pressure values. There was consensus on the upward referral criteria for patients with special types of diabetes and with newly diagnosed diabetes. In contrast, the referral criteria for diabetic complications were relatively vague, especially with the lack of severity classification for chronic complications.Conclusion:The two-way referral criteria for diabetes mellitus have been constantly developing, while the criteria for downwards referral to the community need to be further improved.

Objective:To standardize the management of auditory hallucination symptoms in inpatients with mental illness and develop an expert consensus on the management of auditory hallucinations in hospitalized psychiatric patients.Methods:From March 2023 to July 2023, the Mental Health Committee of the Chinese Nursing Association focused on the key issues in the management of auditory hallucinations symptoms in inpatients with mental illness, based on clinical practice, using literature analysis combined with the work experience of mental health experts, and formed the first draft of the expert consensus on the management of auditory hallucinations in inpatients with mental illness (hereinafter referred to as the consensus).
