Objective:To investigate the clinical features and prognosis of neuro-Beh?et′s syndrome (NBS) in children.Method:The clinical, brain magnetic resonance imaging and laboratory data of 5 children with NBS diagnosed in the Department of Pediatrics, General Hospital of Ningxia Medical University and Department of Rheumatology and Immunology, Children′s Hospital Affiliated to Capital Institute of Pediatrics from April 2014 to April 2024 were analyzed retrospectively. The follow-up method was retrospective outpatient or inpatient visit to evaluate the treatment effect of NBS.Result:Among the 5 NBS cases, 2 were male and 3 were female. The age of admission ranged from 8 to 17 years, the time from onset to diagnosis was 2 days to 4 years. Two patients had dizziness, headache and convulsions during the treatment of NBS, 1 patient had disturbance of consciousness, 1 patient gradually developed aphasia, limb movement disorder, dysphagia and muscle weakness after 4 years of Behcet's syndrome, and 1 patient had no clinical symptoms. C-reactive protein and erythrocyte sedimentation rate were increased in 4 cases, and cerebrospinal fluid white blood cells and immunoglobulin G were increased in 1 case. Brain magnetic resonance imaging of 4 children showed multiple lesions, including bilateral frontal lobe, occipital lobe, parietal lobe, periventricular and corpus callosum lesions. Brain magnetic resonance imaging showed multiple demyelinating diseases in 1 case, and cervical and thoracic magnetic resonance imaging showed slender cervical and thoracic spinal cord. All patients were treated with corticosteroids combined with immunosuppressants or biological agents. The children were followed up for 6 months to 4 years, and 4 cases had good treatment results, and 1 case finally gave up treatment.Conclusions:The clinical manifestations of NBS are not specific, and brain magnetic resonance imaging shows that the lesion location and morphology are not specific. NBS children treated with corticosteroids combined with immunosuppressive agents or biological agents have a good prognosis.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Sesquiterpenoids are widely found in nature, while nitrobenzoyl sesquiterpenoids are relatively rare. Twelve natural nitrobenzoyl sesquiterpenoids were all derived from marine Aspergillus fungi, which are typical natural products with marine characteristics. These natural products exhibit good antitumor, antiviral, and inhibition of osteoclast differentiation activity, especially in the treatment of osteoclast-related diseases, showing good medicinal development value. This article reviews the natural product sources, chemical structure, chemical synthesis, biosynthesis, bioactivity, and pharmacological mechanisms of nitrobenzoyl sesquiterpenoids and predicts and discusses their absorption, distribution, metabolism, excretion, toxicity (ADME/T), and drug-likeness, providing a comprehensive understanding of the natural products of nitrobenzoyl sesquiterpenoids from marine sources and their potential for pharmaceutical development.

Chronic heart failure （CHF） is a clinical syndrome resulting from damage to the myocardium， leading to changes in the function or structure of the heart and causing reduced pumping and/or filling capacity. Its pathogenesis is complex， potentially involving myocardial fibrosis， apoptosis and autophagy of cardiomyocytes， inflammatory responses， oxidative stress， and myocardial remodeling. Our team believes that the fundamental pathogenesis of CHF is heart-Qi deficiency， with the disease location in the heart， which is closely related to other organs. Due to heart-Qi deficiency， blood circulation weakens， leading to blood stasis， which in turn generates water-dampness and phlegm turbidity that accumulate over time and become toxic. The interaction between water stasis， Qi stagnation， blood stasis， and phlegm toxicity further weakens the body， creating a vicious cycle （deficiency， stasis， water retention， and toxicity） that is difficult to resolve. Under physiological conditions， the nuclear factor-κB （NF-κB） signaling pathway functions normally， maintaining vital activities and immune responses. However， in pathological states， the NF-κB signaling pathway becomes imbalanced， triggering inflammatory responses and other issues. Research has shown that traditional Chinese medicine （TCM） can regulate the NF-κB signaling pathway through multiple pathways， targets， and effects， effectively improving the progression of CHF. As a result， this has become a research hotspot for the prevention and treatment of the disease. Guided by TCM theory， this research group reviewed the literature to summarize the activation pathways of the NF-κB pathway and its interactions with other pathways. Additionally， the group summarized the research progress on the regulation of the NF-κB pathway in the treatment of CHF using Chinese medicines， their active ingredients， Chinese medicine compounds， and Chinese patent medicines. This study is expected to clarify the mechanisms and targets by which TCM treats CHF by regulating the NF-κB pathway， thereby guiding clinical treatment and drug development for CHF.

Objective This paper aims to construct a system integrating mixed reality technology with artificial algo-rithm and to evaluate its effectiveness in vascular localization during anterolateral thigh perforator flap surgery to provide new insights for clinical practice.Methods Twenty patients undergoing anterolateral thigh perforator flap repair were selected.After attaching positioning devices on the lower limb,CT angiography(CTA)scans were performed.The 2D data obtained were converted into a 3D model of the positioning device and vessels.Mixed reality technology was uti-lized to achieve 3D visualization of perforator vessels.An artificial algorithm was developed in HoloLens 2 to match the positioning device automatically with its 3D model intraoperatively to overlap the perforator vessels with their 3D mod-els.The number of perforator vessels identified within the flap harvesting area and the actual number detected during sur-gery were recorded to calculate the accuracy rate of vessel identification based on CTA data reconstruction.The distance between the perforator vessel exit points located by the system and the actual exit points was measured,and the error val-ues were calculated.The surgical time required for the system to harvest the anterolateral thigh perforator flap was docu-mented and compared with the surgical time required by conventional methods.The clinical applicability of the system was discussed.Results The CTA data reconstruction identified 30 perforator vessels,while the actual number found during surgery was 32,resulting in an identification accuracy rate of 93.75％.The average distance between the perfora-tor vessel exit points located by the system and the actual exit points was(1.65±0.52)mm.The average surgical time for flap harvesting with the assistance of the system was(43.45±4.6)min compared with(57.6±7.9)min required by conven-tional methods.All perforator flaps survived the procedure.One case of flap infection occurred seven days postoperative-ly,and one case of partial flap necrosis was treated with symptomatic therapy,resulting in delayed healing.Conclusion The system constructed in this paper can achieve 3D visualization of perforator vessels through mixed reality technology and improve the accuracy of perforator vessel localization using artificial algorithms,hence demonstrating potential ap-plication in anterolateral thigh perforator flap harvesting surgeries.

Objective: To explore the impact of smart physical education assignment on physical health of male university students, so as to provide theoretical support and practical references for physical health improvement of male university students and implementing smart sports assignments. Methods: From September 2023 to January 2024, 317 sophomore male students from six Taekwondo elective classes at Hunan Institute of Engineering were selected and were randomly divided into an intervention group (n=157) and a control group (n=160). The intervention group was given sports assignments twice a week through smart means with an intervention duration of 15 weeks, each time for 25-35 minutes, in addition to the teaching according to the public course syllabus, while the control group was taught according to the public course syllabus. The physical and health indicators of both groups were tested before and after intervention,then the differences in various physical health indicators between two groups of students before and after intervention were compared through ttest and Mann-Whitney U test. Results: After the intervention, the vital capacity, 50 m run, sitandreach, 1 000 m run, and pullup scores of the intervention group significantly improved compared to those before intervention. The scores improved from (3 918.27±737.34)mL, 7.88(7.53,8.45)s, 9.80(2.70,15.75) cm, 4.30(4.12,4.50) min and 3.00(0.00,7.50) times to (4 574.19±800.61) mL, 7.65(7.37,8.12)s, 17.20(11.80,21.55)cm, 4.13(3.58,4.31)min and 5.00(1.00,10.00) times,respectively (t/Z=-7.60, 2.61, -8.39, 5.62, -2.72, P<0.05). Before intervention, there was no statistically significant difference in physical health indicators between the intervention group and the control group (P>0.05).After intervention,the scores of the intervention group on the vital capacity,50 m run,sitandreach,1 000 m run and pullup, were significantly higher than those of the control group [(4 310.97±808.90)mL, 7.75(7.40,8.30)s, 14.10(8.42,17.87)cm, 4.29(4.08,4.45)min and 4.00(1.00,7.00) times] (t/Z=2.91, -4.55, -4.75, -4.15, 2.58, P<0.05). Conclusions Having 25-35 min smart physical education assignment twice a week can effectively improve physical health level of male college students. It is recommended to assign appropriate amount of smart sports homework to improve physical health level of college students, while ensuring the amount and intensity of physical activity in public physical education courses.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

The multiple systemic symptoms appearing during the convalescence of novel coronavirus infection(COVID-19)are called long-term symptoms after COVID-19,also named as long COVID.Traditional Chinese medicine(TCM)has unique advantages in the treatment of long COVID.In the view of Professor ZHANG Zhong-De,the novel coronavirus infection belongs to the category of damp-toxin pestilence in TCM.During the convalescence of novel coronavirus infection,the damp-toxin pathogen causes the dysfunction of qi,blood,yin and yang of zang-fu organs,and then results in the consumption of yang qi or the depletion of fluid and blood.Damp-turbidity obstructing qi movement and entering collaterals and then developing into blood stasis is the key pathogenesis of long COVID.Therefore,the therapeutic principle of harmonizing yin,yang,qi and blood of the five zang-organs is proposed,and the methods for transporting and transforming damp-toxin and phlegm-turbidity,regulating qi,activating blood and removing stasis should be adopted.According to the exuberance or decline of qi,blood and body fluid,and yin and yang of the five zang-organs,the Fuzheng Series Formulas(series formulas for supporting healthy qi)were recommended for the specific syndrome types:Fuzheng Shengbai Formula can be used for the syndrome of deficiency of original qi;Fuzheng Yifei Formula can be used for lung-spleen-kidney deficiency syndrome;Fuzheng Anshen Formula can be used for the syndrome of liver qi stagnation and heart-spleen deficiency.During the treatment,Professor ZHANG Zhong-De makes the modification of drugs indicated for the retention sites of damp-toxin and turbid qi,and addresses the importance of spleen and stomach in the whole treatment process by protecting spleen and stomach,so as to promote the rehabilitation of patients after novel coronavirus infection and improve their quality of life.

Objective To determine the effective dose of dexmedetomidine administered intranasally combined with oral midazolam sedation before pediatric magnetic resonance image(MRI).Methods This is a prospective modified sequential study.Children scheduled for MRI at the Children's Hospital of Zhejiang University School of Medicine from February to March 2023,aged 1 month to 6 years old,with a weight of 6.0-23.5 kg,were enrolled in this study.All children received 0.5 mg/kg oral midazolam,followed by intranasal dexmedetomidine.The initial dose of dexmedetomidine was 0.5 μg/kg,and the intranasal dose of dexmedetomidine was determined using the modified Dixon's up-and-down method with increments or decrements of 0.1 μg/kg.Probit analysis was used for calculating the half effective dose(ED50),95%effective dose(ED95)and the corresponding 95%confidence interval(CI)of intranasal dexmedetomidine combined with oral midazolam for pediatric sedation during MRI.The sedation onset time,wake-up time,vital signs and adverse reactions were recorded.Results Among all the children,the sedation onset time of successful sedation children was(31.21±7.47)min,and the wake-up time was(81.21±26.04)min.The ED50 for effective sedation with intranasal dexmedetomidine combined with oral medication at a dose of 0.5 mg/kg was calculated to be 0.392 μg/kg,with a 95%CI of 0.302-0.461 μg/kg;the ED95 was 0.549 μg/kg,with a 95%CI of 0.473-0.996 μg/kg.There was a statistically significant difference(P<0.05)in heart rate and diastolic blood pressure after sedation compared to the baseline before medication.Two cases of restlessness during the awakening period were observed,but no other adverse reactions occurred.Conclusions The sedation regimen of intranasal dexmedetomidine combined with oral midazolam is non-invasive,easy to implement,safe,and effective.It can be widely used in pediatric MRI.

Objective:To explore the characteristics of SLCO1B1/ SLCO1B3 gene variants among children with Rotor syndrome (RS). Methods:Four children who were admitted to the Department of Hepatology of Hunan Children′s Hospital between January 2019 and January 2022 were selected as the study subjects. Trio-whole exome sequencing was carried out for the four families, and gel electrophoresis was used to verify an insertional variant of long-interspersed element-1 (LINE-1).Results:Genetic testing has identified three variants of the SLCO1B1 gene, including c. 1738C>T (p.R580*), c. 757C>T (p.R253*) and c. 1622A>C (p.Q541P), and two variants of the SLCO1B3 gene, including c. 481+ 22insLINE-1 and c. 1747+ 1G>A among the children. Three of them were found to harbor homozygous variants of the SLCO1B1/ SLCO1B3 genes, and one has harbored compound heterozygous variants. Sanger sequencing confirmed the existence of all variants, and gel electrophoresis has confirmed the existence of the LINE-1 insertional variant of about 6 kb within intron 6 of the SLCO1B3 gene in all children. Conclusion:The pathogenesis of the RS among the four children may be attributed to the variants of the SLCO1B1/ SLCO1B3 genes. The LINE-1 insertion variant of the SLCO1B3 gene may be common among Chinese RS patients.
