BACKGROUND:Bone marrow mesenchymal stem cells have been widely used to treat neurological diseases.However,due to limitations of the blood-brain barrier,low survival rate and differentiation rate of stem cells at damaged sites,the therapeutic effect is limited. OBJECTIVE:To investigate the effects of Shexiang Huangqi compound dripping pills on proliferation,migration and astrocyte differentiation of bone marrow mesenchymal stem cells. METHODS:Male SD rats were treated with Shexiang Huangqi compound dripping pills for 5 days after continuous gavage.Blood was collected from the abdominal aorta and serum was separated for later use.The effect of 5%,10%and 20%drug-containing serum on the proliferation of bone marrow mesenchymal stem cells was detected by CCK-8 assay.The effect of 10%drug-containing serum on lateral migration of bone marrow mesenchymal stem cells was observed by scratch test.Bone marrow mesenchymal stem cells were cultured in Transwell cells.The effects of 10%drug-containing serum on longitudinal migration of bone marrow mesenchymal stem cells were observed by crystal violet staining and DAPI nuclear staining.Differentiation of bone marrow mesenchymal stem cells into astrocytes was observed by inducing solution with 10%drug-containing serum or co-culture with astrocytes. RESULTS AND CONCLUSION:(1)10%and 20%drug-containing serum promoted cell proliferation more significantly on days 2 and 3,and there was no statistical difference between the two concentrations.(2)At 30 and 48 hours,bone marrow mesenchymal stem cell migration in 10%drug-containing serum group was significantly higher than that in the control group.(3)The number of bone marrow mesenchymal stem cells filtered through Transwell cells in 10%drug-containing serum group was higher than that in the control group.(4)10%drug-containing serum might promote the differentiation of bone marrow mesenchymal stem cells to astrocytes,but the differentiation effect was weak,and astrocytes might further promote the differentiation of bone marrow mesenchymal stem cells into astrocytes induced by drug-containing serum.(5)The results exhibited that the 10%drug-containing serum could promote the proliferation and migration of bone marrow mesenchymal stem cells in vitro.Co-culture with astrocytes may promote the differentiation of bone marrow mesenchymal stem cells towards astrocytes.

Objective To explore the effect of transcranial direct current stimulation(tDCS)based on music therapy on insomnia. Methods From July,2023 to April,2024,70 patients with insomnia in the Fourth Affiliated Hospital of Soochow Univer-sity were randomly divided into control group(n=35)and observation group(n=35).Both groups accepted mu-sic therapy;moreover,the observation group accepted tDCS,and the control group accepted sham tDCS,for four weeks.They were assessed with Pittsburgh Sleep Quality Index(PSQI)total score and sub-score,Hamilton De-pression Scale 17-item(HAMD-17),Hamilton Anxiety Scale(HAMA),Chinese version of Stress Perception Scale(CPSS);and the relative power of resting-state electroencephalography(EEG)and mean blood flow veloci-ty(Vm)of each cerebral artery with transcranial Doppler were measured before and after treatment. Results Five cases dropped down in the control group,and four in the observation group.PSQI total score and sub-score,HAMD-17 score,HAMA score and CPSS score(|t|>3.503,P<0.01)in the observation group decreased after treatment,and were less in the observation group than in the control group(|t|>2.304,P<0.05),except sleep duration,sleep efficiency and CPSS scores.The relative power of δ and θ increased in the observation group,and decreased in α,β and γ(|t|>6.468,P<0.001),and were better in the observation group than in the control group(|t|>2.395,P<0.05).The Vm of each artery increased in the observation group(|t|>4.624,P<0.001),and were more in the observation group than in the control group(|t|>2.147,P<0.05). Conclusion tDCS based on music therapy may further improve sleep quality and EEG activity,increase cerebral blood flow velocity,and reduce adverse emotions in insomnia patients.

Objective This study aims to investigate the feasibility and safety of Da Vinci robotic-assisted thoracoscopy for resecting mediastinal tumors in pediatric patients.Methods From November 2020 to June 2023,a total of 80 pediatric patients undergoing mediastinal tumor resection at Wuhan Children's Hospital were randomly assigned into two groups,with each group consisting of 40 participants.The control group underwent conventional thoracoscopy,while the observation group underwent Da Vinci robotic-assisted thoracoscopy.This study aimed to compare perioperative indicators between the two groups and establish learning curves based on surgical duration and intraoperative blood loss.Additionally,it assessed levels of pain mediators and stress response markers before surgery and at 24 hours post-surgery,as well as postoperative complications.Inflammatory marker levels were evaluated one month after surgery,and the children's quality of life was measured using the Pediatric Quality of Life Inventory(PedsQL)Generic Core Scales before surgery and one month post-surgery.Results The surgical duration for the observation group and the control group was(1.76±0.33)hours and(2.82±0.62)hours,respectively,and the intraoperative blood loss was(49.83±6.39)mL and(71.55±8.19)mL,respectively.Furthermore,the post-operative drainage time,drainage volume,and hospital stay for the observation group were all lower than those for the control group(P<0.05).After surgery,the levels of BK,5-HT,NPY,and PGE2 in the observation group were(8.06±1.06)mg/L,(170.20±13.21)ng/L,(201.82±13.52)mg/L,and(241.82±15.32)ng/L,respectively,indicating lower levels of pain mediators,stress response markers,and inflammatory factors compared to the control group(P<0.05).he overall incidence of complications was 2.50%in the observation group as opposed to 20.00%in the control group.Moreover,there was a statistically significant improvement in quality of life after surgery within the observation group when compared to that within the control group(P<0.05).Conclusion Da Vinci robotic-assisted thoracoscopy demonstrates enhanced feasibility and safety in pediatric mediastinal tumor resection,thereby justifying its clinical promotion.

Objective:To observe the clinical effect of adjustable silicone strap suspension in the treatment of myasthenia gravis ptosis.Methods:From January 2019 to January 2020, 60 patients with myasthenia gravis ptosis (35 males, 25 females, age distribution from 25 to 58 years, with average of 35.63 years) were collected from the Department of Ophthalmoplasty of Aier Eye Hospital affiliated to Wuhan University. They were divided into control group and observation group, with 30 cases in each group. The observation group was treated with adjustable silicone band suspension, and the correction effect, satisfaction, recovery status, ocular surface function index, recurrence rate and complications of the two groups were compared.Results:The excellent rate of operation in the observation group was 93.33% (28/30), which was significantly higher than 63.33% (19/30) in the control group (χ 2=6.29, P<0.05), and the satisfaction of patients in the observation group was 100% (30/30), which was significantly higher than 76.67% (23/30) in the control group (χ 2=5.82, P<0.05). The preoperative corneal curvature and fluorescein staining in the observation group and the control group were significantly lower than those in the postoperative state ( t=6.17, 21.48, P<0.05). The corneal curvature and fluorescein staining score of the observation group were significantly higher than those of the control group at 3 months after surgery ( t=3.00, 9.06, P<0.05). There was no significant difference between the two groups in the incidence of complications such as eyelid imclosure, upper eyelid inversion and unnatural upper eyelid curvature (χ 2=0.19, P>0.05). Follow up at 3 months after surgery, the recurrence rate in the observation group was lower than that in the control group (χ 2=4.63, P<0.05). Conclusions:Surgery is an option for patients with myasthenia gravis ptosis who are not responding well to medical treatment and whose condition is stable. Adjustable silicone strap suspension for the treatment of myasthenia gravis ptosis can significantly improve the surgical success rate and patient satisfaction, with low postoperative complication rate and recurrence rate, which is suitable for clinical application.

Objective:To investigate the effects of computerized cognitive remediation therapy (CCRT) combined with social skill training on the improvement of negative symptoms of schizophrenia.Methods:A total of 102 schizophrenic patients who received treatment in Shanxi Province Social Welfare Kangning Psychiatry Hospital from March 2019 to June 2021 were included in this study. They were randomly divided into an intervention group and a control group ( n = 51/group). During the intervention process, because of the reasons such as midway discharge, only 93 patients were included in the final analysis, consisting of 47 patients in the intervention group and 46 patients in the control group. All patients received social skills training. Patients in the intervention group received 8-week CCRT. The Positive and Negative Syndrome Scale and Social Skills Checklist were used to evaluate curative effect in the two groups. Results:After treatment, total score of the Positive and Negative Syndrome Scale and the score of negative symptoms in the intervention group were (46.36 ± 9.33) points and (11.15 ± 3.53) points, respectively, which were significantly lower than (51.06 ± 10.26) points and (16.42 ± 4.75) points in the control group ( t = 2.07, 5.41, both P < 0.05). The total score of Social Skills Checklist, conflict resolution ability score and relationship building ability score in the intervention group were (16.05 ± 6.85) points, (3.36 ± 1.65) points and (3.14 ± 1.83) points, respectively, which were significantly lower than (21.08 ± 8.24) points, (5.92 ± 2.35) points and (6.75 ± 2.51) points, respectively ( t = 2.87, 5.34, 7.00, all P < 0.01). Conclusion:CCRT combined with social skill training can effectively improve the negative symptoms of patients with schizophrenia.

Gout is a metabolic disorder characterized by elevated uric acid levels， often caused by purine metabolism disturbances or abnormalities in uric acid （UA） excretion. Currently， western medicine is the primary treatment approach for gout， but it often comes with significant side effects. Traditional Chinese medicine （TCM） has gained significant development in the field of gout treatment due to its safety and effectiveness. This article aimed to explore TCM strategies in the management of gout， providing insights for the development and application of TCM in the field of gout treatment. Relevant literature retrieved from PubMed， Web of Science， China National Knowledge Infrastructure （CNKI）， Wanfang Data， and VIP databases was systematically analyzed with such keywords as "Chinese herbal medicine"， "traditional Chinese medicine"， "TCM"， and "gout". The findings suggest that TCM can treat gout through a syndrome differentiation approach that encompasses four pathological mechanisms： phlegm， blood stasis， dampness， and deficiency， simultaneously addressing both excess and deficiency syndromes in gout. Based on the pathological characteristics of four syndromes， namely dampness-heat retention， blood stasis-heat obstruction， phlegm-turbidity obstruction， and liver and kidney Yin deficiency， TCM adopts specific treatment approaches including clearing heat and promoting diuresis， activating blood and resolving stasis， resolving phlegm and reducing turbidity， and nourishing the liver and kidneys. These targeted approaches have proven to be effective in gout management. The main mechanisms of TCM in gout management include inflammation resistance ［regulating inflammatory pathways such as tumor necrosis factor-alpha （TNF-α）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， interleukin-8 （IL-8）， and other chemokines， as well as inflammatory signaling pathways like nuclear factor-kappa B （NF-κB） and NOD-like receptor protein 3 （NLRP3）］， uric acid reduction （modulating uric acid transporters and inhibiting xanthine oxidase （XOD） activation）， antioxidant stress mitigation （suppressing reactive oxygen species and regulating nitric oxide， malondialdehyde， and other oxidative markers）， and immune system regulation.

Objective To perform quantitative evaluation of fat and iron deposition in the pancreas of patients with acute pancreatitis (AP) based on the IDEAL-IQ quantitative parameters fat fraction (FF) and relaxation rate (R 2 * ), and to investigate the efficacy of this technique in the diagnosis of AP. Methods A total of 72 patients with AP who were diagnosed and treated in The First Affiliated Hospital of Baotou Medical College, Inner Mongolia University of Science and Technology from October 2020 to October 2021, were enrolled as case group, and 82 healthy controls who underwent physical examination during the same period of time were enrolled as control group. The abdominal IDEAL-IQ sequence test was performed for both groups using GE 3.0T magnetic resonance instrument, and FF and R 2 * values were measured on post-processing workstation. The t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. A receiver operating characteristic (ROC) curve analysis was performed for the parameters with statistical significance, and area under the ROC curve ( AUC ) was used to evaluate the diagnostic efficacy of parameters. Results Compared with the control group, the case group had significantly higher FF value ( Z =-10.01, P < 0.001) and R 2 * value ( Z =-3.73, P < 0.001), while there were no significant differences in FF and R 2 * values between mild AP and moderate-to-severe AP ( P > 0.05). FF value had a sensitivity of 100% and a specificity of 90.2% in the diagnosis of AP, while R 2 * value had a sensitivity of 48.6% and a specificity of 86.6% in the diagnosis of AP. Conclusion The quantitative parameter FF value of magnetic resonance IDEAL-IQ technique has relatively high sensitivity and specificity in the diagnosis of AP, and it is a specific index for the diagnosis of AP and holds promise for clinical application.

Graves′ ophthalmopathy(GO) is an autoimmune disease closely related to thyroid diseases. Clinical manifestations of GO are various, making it hard to be diagnozed and treated. There are a number of treatments available clinically, however etiological treatment remains scarce. The choice of treatment, the evaluation of therapeutic effect and the prediction of patients′ outcomes should be rooted in the evaluation of patients′ condition. In this review, the clinical characteristics of GO were analyzed, and key points of assessment including risk factors, clinical activity, disease severity, quality of life and psychological status were also proposed. Clinicians are encouraged to shed more focus on the assessment of GO.
