Objective: To analyze the relationship between 24 h movement behaviors and cognitive function in children and adolescents, as well as the isotemporal substitution benefits, in order to provide a basis for developing cognitive development intervention strategies among children and adolescents. Methods: Relevant studies were searched in the Web of Science, PubMed, Embase, EBSCO, and China National Knowledge Infrastructure databases from their inception to November 30, 2024. Systematic evaluation was performed after document screening, data extraction and quality assessment. Results: A total of 24 highquality studies were included, comprising 35 295 children and adolescents aged 3-18 years. Adhering to the 24 h activity guidelines was associated with better cognitive performance (19 studies). Additionally, substituting 5-30 minutes per day of moderate to vigorous physical activity (MVPA) or sleep (SLP) for sedentary behavior (SB) or light physical activity (LPA) were associated with improvements in cognitive function (7 studies). There were inconsistencies in the effects of different types of SB (learning or entertainment) on cognitive function. Conclusions Adherence to the 24 h activity guidelines supports cognitive development in children and adolescents, with MVPA and SLP as key intervention targets. Increasing the proportion of MVPA, ensuring adequate SLP, and limiting recreational SB and screen time might be helpful to enhance the combined benefits of these three behaviors.

OBJECTIVE To systematically evaluate the efficacy and safety of the sedative effect of remimazolam in endoscopy and to compare it with propofol and midazolam. METHODS Search PubMed, Embase, Cochrane Library, Wanfang database, CNKI and other databases to collect the literature of randomized controlled trials of remimazolam for sedation in endoscopy. The search period was from 2018 onwards when remimazolam was approved for clinical trials until April 2022. The search strategy included the following variable keywords: remimazolam, gastroscopy, bronchoscopy, and colonoscopy. The quality of the included literature was assessed and the collected data were subjected to meta-analysis by RevMan 5.4 software. RESULTS Ten relevant RCTs involving midazolam and propofol, involving a total of 2 076 patients were included in the analysis. The results showed that the sedative effect of remimazolam was significantly higher than that of midazolam [OR=0.03, 95%CI(0.02, 0.05), I2=0%, P<0.000 01]; but lower than that of propofol [OR=11.32, 95%CI(2.12, 60.56), I2=0%, P=0.005]. The onset time of remimazolam was longer than that of propofol, but shorter than that of midazolam; the recovery time was faster than that of propofol and midazolam. Compared with midazolam, there was no significant difference in the incidence of adverse reactions. Compared with propofol, remimazolam was associated with lower rates of hypotension, slowed heart rate, hypoxemia, and injection pain, but higher risk ratio of nausea, with no difference invomiting. CONCLUSION The sedative effect and onset of action of remimazolam are better than midazolam but less than propofol when used for endoscopy. Wake-up time is faster than that of propofol and midazolam. The incidence of respiratory and circulatory depression is lower with remimazolam than with propofol, and there are no significant differences in adverse effects compared with midazolam.

Objective To understand the epidemic status of biological stings on an island and the knowledge about environmental emergencies of personnel stationed on the island.Methods With convenience sampling,we investigated 270 personnel using a self-designed anonymous questionnaire based on clinical treatment situation and on-the-spot investigation of the island.Results A total of 270 questionnaires were distributed,and 254 valid questionnaires were returned,with an effective rate of 94.07％.A total of 164(64.57％)personnel had a history of stings,with median times of 2(0,5).The main clinical symptoms were local swelling and pain(142 cases,86.59％)and pruritus(110 cases,67.07％).The personnel scored 14(11,17)for the first aid knowledge about island environmental emergencies(the full score was 26).The vast majority of personnel(227 cases,89.37％)believed that it was necessary to learn the knowledge about island environmental emergencies,and the majority of personnel(186 cases,73.23％)hoped to learn through centralized teaching.Conclusion The environmental emergencies represented by biological stings are becoming increasingly serious,so it is necessary to carry out multiple prevention and environmental control measures,and to carry out regular and long-term training for personnel stationed on islands.

Objective To analyze the characteristics of pattern elements and the distribution of patterns of femoral head necrosis, hip osteoarthritis, and hip rheumatoid arthritis, in order to provide a theoretical basis for the "different diseases with the same pattern" of chronic bone diseases. Methods A cross-sectional survey was conducted to select patients with femoral head necrosis Association Research Circulation Osseous Ⅰ-Ⅱ stages, hip osteoarthritis Kellgren & Lawrence Ⅰ-Ⅱ stages, and acute or subacute hip rheumatoid arthritis who visited the Minimally Invasive Arthrology Department, Traumatology Department, and Rheumatology and Immunology Department of Beijing University of Chinese Medicine Third Affiliated Hospital from June 2020 to June 2022. The " case report form - traditional Chinese medicine pattern manifestation scale" previously developed by our team was used to collect the pattern manifestations, which were included into an Excel 2020 spreadsheet to establish a database. SPSS 20.0 software was used for factor analysis and cluster analysis to extract pattern element information, such as disease nature and location, in order to summarize the characteristics of pattern elements, the distribution of patterns, and the similarities and differences of the three kinds of early hip joint diseases.Results A total of 410 patients were included, including 150 patients with femoral head necrosis, 160 patients with hip osteoarthritis, and 100 patients with hip rheumatoid arthritis. The pattern elements of the disease nature of femoral head necrosis include phlegm (dampness), blood stasis, yang deficiency, essence deficiency, and qi deficiency. The pattern types were initially divided into four categories: syndrome of meridian obstruction (43.33％), syndrome of phlegm and blood stasis blocking collaterals (38.00％), syndrome of liver and kidney deficiency (12.00％), and syndrome of kidney essence deficiency (6.67％). The pattern elements of the disease nature of hip osteoarthritis include phlegm (dampness), blood stasis, qi deficiency, essence deficiency, yang deficiency, and cold (dampness). The pattern types were preliminarily divided into five categories: syndrome of spleen and kidney deficiency (37.50％), syndrome of meridian obstruction (26.87％), syndrome of cold and dampness obstruction (18.75％), syndrome of phlegm and blood stasis obstruction (9.38％), and syndrome of liver and kidney deficiency (7.50％). The pattern elements of the disease nature of hip rheumatoid arthritis include phlegm (dampness), blood stasis, qi deficiency, yin and yang deficiency, cold (dampness), and essence deficiency. The pattern types were preliminarily divided into four categories: syndrome of phlegm and blood stasis obstruction (34.00％), syndrome of cold and dampness obstruction (28.00％), syndrome of blood stasis blocking collaterals (23.00％), and syndrome of liver and kidney deficiency (15.00％). Overall, the top five pattern manifestations of the three kinds of hip joint diseases were hip joint pain (96.59％), tenderness (93.90％), fixed pain (87.56％), heavy joints (85.37％), and sourness of lower limbs (75.37％). The pattern elements of the disease nature include phlegm (dampness), blood stasis, qi deficiency, etc. The pattern types were preliminarily divided into five categories: syndrome of phlegm stasis blocking collaterals (33.17％), syndrome of meridian obstruction (31.95％), syndrome of cold dampness obstruction (21.46％), syndrome of liver and kidney deficiency (7.32％), and syndrome of spleen and kidney deficiency (6.10％). There were 21 similar pattern manifestations in the three kinds of early hip joint diseases, with blood stasis and spleen deficiency being the main pattern.Conclusion The common pattern characteristics of three kinds of early hip joint diseases are spleen deficiency and blood stasis. In addition, femoral head necrosis is accompanied with phlegm-dampness pattern, hip osteoarthritis is accompanied with kidney deficiency and phlegm-dampness pattern, hip rheumatoid arthritis is accompanied with kidney deficiency and cold-dampness pattern.

As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

Objective:To systematically review the factors related to the aggressive behavior of hospitalized patients with schizophrenia in China.Methods:CNKI,Wanfang,VIP,China Biomedical Literature Database,PubMed,Cochrane Library,and Embase databases were searched to collect case-control studies on factors related to aggression in hospitalized patients with schizophrenia in China from its inception to June 2023.Analysis was per-formed using ReviewManager 5.3 to calculate pooled OR(95％CI)values.Results:Thirty-three studies were in-cluded.Medical staff coercive measures(OR=3.86,95％CI:2.75-5.43),unemployment(OR=1.44,95％CI:1.14-1.81),positive family history(OR=2.97,95％CI:2.29-3.87),poor medication compliance(OR=4.37,95％CI:3.36-5.69),young age(OR=3.13,95％CI:2.66-3.69),involuntary hospitalization(OR=3.34,95％CI:2.81-3.97),depression(OR=2.11,95％CI:1.68-2.66),emotional abuse(OR=1.13,95％CI:1.04-1.23),male(OR=2.70,95％CI:2.20-3.31),delusions(OR=2.14,95％CI:1.69-2.71),auditory hallucina-tions(OR=2.23,95％CI:1.70-2.94),and major life events(OR=3.21,95％CI:1.90-5.42)and previous history of aggressive behavior(OR=2.20,95％CI:2.06-2.34)were risk factors associated with aggressive be-havior in Chinese patients with schizophrenia,and social support(OR=0.46,95％CI:0.31-0.67)was a protec-tive factor.Conclusion:There are various factors related to aggressive behavior in hospitalized Chinese patients with schizophrenia,and medical staff should identify high-risk groups early according to the relevant factors,and effec-tively intervene in controllable factors to reduce the occurrence of aggressive behavior.

Objective To explore the influencing factors of medication experience in patients with schizophrenia based on benefit-risk perception.Methods Patients with stable schizophrenia who were hospitalized in 2 tertiary psychiatric hospitals in Heilongjiang Province from September to December 2023 were selected by convenience sampling method.A convergent mixed method was adopted.In quantitative study,data of 400 patients were collected by general situation questionnaire,Subjective Well-being Under Neuroleptic Treatment Scale,the Living with Medicines Questionnaire,Beliefs about Medication Questionnaire,Positive and Negative Syndrome Scale.Binary logistic regression analysis was used to explore the influencing factors of medication experience in patients with schizophrenia.15 patients with adverse medication experience in quantitative study were selected for qualitative study,and the interview data were sorted and analyzed according to the topic frame analysis method.Results Quantitative results:medication burden,medication beliefs,and psychiatric symptoms of patients with schizophrenia were influential factors of medication experience(P<0.05).Qualitative results:the medication experience of schizophrenia patients includes 4 themes,namely perceived necessity of medication,perceived benefit of medication,perceived risk of medication,and the need for multi-party cooperation to improve the medication experience.The results of quantitative and qualitative research are complementary in terms of perceived benefit,consistent in terms of perceived risk,and expansive in terms of perceived value.Conclusion Psychiatric nurses can reduce patients'perceived risk of medication,enhance the perceived benefit of medication,and then improve patients'adverse medication experience and promote mental rehabilitation.

This article reports a case data of primary malignant melanoma of the penis admitted to the Affiliated Hospital of Qinghai University. A 56-year-old patient was admitted to the hospital 1 month after the discovery of a penile mass. Physical examination: An irregular cauliflower-like mass about 1.5 cm×2.0 cm in size was seen below the external urethral orifice, covered with yellow necrotic tissue, and tenderness was positive. Several nodes were palpable in the left and right groin areas, tenderness positive. Laboratory examination showed no abnormality. The CT examination of head, chest, abdomen and pelvis showed no obvious abnormality. The biopsy of the penile mass showed malignant melanoma of the penis. The pathological results of biopsy of the right inguinal lymph node considered local inflammation. Combined with the patient's medical history, physical examination, imaging examination and lymph node biopsy results, a diagnosis of primary penile malignant melanoma was made. Partial penile resection was performed, and the postoperative pathological diagnosis was malignant melanin invasion of the epidermis with ulceration. There was no local recurrence and metastasis during the 9-month follow-up.

AIM: To observe and compare the clinical efficacy and safety of remimazolam and propofol alone and in combination in endoscopic retrograde cholangiopancreatography (ERCP) anesthesia. METHODS: A total of 120 patients undergoing elective ERCP were divided into the propofol group (P group), the remimazolam group (R group), and the remimazolam combined with propofol group (RP group) according to a random number table, with 40 patients in each group, and the three groups completed anesthesia according to the designated drug regimen (propofol in group P; remimazolam in group R; and remimazolam combined with propofol in group RP). General information, operation time and awakening time of the patients in the three groups were compared, as well as oxygen saturation (SpO

Objective To investigate the repairing effect of ursolic acid extracted from Hippophae rhamnoi-des L.on sciatic nerve injury in rats.Methods After preparing a sciatic nerve damage model,thirty 2-month old Wistar rats were randomly divided into ursolic acid and control groups,with 15 rats in each group.Ursolic acid group was given Ursolic acid 150 mg/(kg·d)by gavage,while the control group was given the same dose of normal saline for 6 weeks.After 6 weeks,H&E staining was used to observe the pathological changes of rat sciatic nerves,and SFI and MNCV were calculated;The expression of NGF in sciatic nerve was detected by immunohistochemistry,and the expression of GAP-43 in L4-L6 spinal cord was detected by Western blotting.Results After 6 weeks,compared to the control group,the number of regenerated nerve fibers in the ursolic acid group increased,the arrangement was slightly regular,the capillary structure was abundant,and the proliferation of fibroblasts decreased;SFI and MNCV%were significantly increased(P<0.05),NGF protein positive expression was significantly increased(P<0.05),and the difference was statistically significant(P<0.05).GAP-43 protein expression in sciatic nerve tissue was significantly increased(P<0.05).Conclusions The intervention of ursolic acid extracted from Hippophae rhamnoides L.can improve the function of rats after sciatic nerve injury,promote the increase of regenerated nerve fibers and the repair of myelin sheath in rats with sciatic nerve injury,which may be related to increased NGF and GAP-43 protein expression in rats.
