To explore the clinical characteristics， imaging features， diagnostic approaches， effective treatment methods， and prognosis of labyrinthine infarction caused by anterior inferior cerebellar artery （AICA） occlusion.A retrospective analysis was conducted on the detailed clinical data of a patient with labyrinthine infarction caused by AICA occlusion， including medical history， symptoms and signs， auxiliary examination results， therapeutic interventions， and follow-up process. The characteristics of this condition were summarized through a review of the relevant literature.Following a comprehensive treatment regimen， including anti-platelet aggregation， lipid regulation， circulation improvement， nerve nutrition， anti-inflammation， and blood pressure and blood sugar regulation， the symptoms of the nervous system were relieved to a certain extent.Labyrinthine infarction caused by AICA occlusion is rare in clinical practice and its diagnosis is difficult. Early and accurate diagnosis and timely and standardized treatment are of great significance for improving the prognosis of patients. Attention should be paid to the management of high-risk factors.

Objective To investigate the clinical characteristics, diagnosis, treatment and prognosis of rare simultaneous ipsilateral renal multifocal tumors. Methods The clinical data of a patient with clear cell renal cell carcinoma(ccRCC)and primary renal leiomyosarcoma(LMS)with liver metastasis were retrospectively analyzed. Results The 70-year-old male patient was admitted due to space-occupying lesions of the right kidney detected by physical examination for 12 days. CT showed space-occupying lesions in the upper and middle parts of the right kidney, suggestive of renal cell carcinoma or renal angiosarcoma. He underwent radical nephrectomy. Postoperative pathology showed the tumor in the upper pole of the right kidney with morphology of ccRCC(solid acinar clear cells), but immunohistochemical(IHC)results showed CK(+), EMA(+), CD10(-), PAX-8(-)(rare phenotype); the tumor in the middle of the kidney showed LMS characteristics(spindle cells, active mitosis), Vim(+)and SMA(+). Four months after operation, abdominal CT scan revealed liver metastasis. The biopsy confirmed metastatic LMS, with IHC results showing Vim(+), CD10(+), RCC(+), CK8/18(-), CK7(-), SMA(+), and Caldesmon(+). Subsequently, a liver biopsy combined with microwave ablation of the tumor was performed. The patient was treated with tirelizumab and anlotinib, but the tumor still progressed. The patient died 11 months after operation. Conclusion Simultaneous ipsilateral ccRCC and LMS are extremely rare in clinic, and the prognosis is poor. At present, there is no standardized treatment plan. Surgery is the main treatment for simultaneous multifocal tumors. After surgery, the pathological characteristics of the two tumors should be considered to formulate a comprehensive drug treatment strategy targeting at different biological behaviors so as to provide reference for clinical practice.

Objective To investigate the expression levels of serum miR-186-5p and miR-942-5p in patients with glioma and their clinical significance.Methods A total of 98 patients with glioma who were treated in this hospital from October 2019 to December 2021 were selected as the monitored group,and 101 healthy indi-viduals who underwent physical examinations a the same time were selected as the control group.Quantitative fluorescent PCR(qPCR)method was applied to detect the expression levels of miR-186-5p and miR-942-5p in serum,and multivariate COX regression was applied to analyze the prognostic factors of glioma patients.Re-ceiver operating characteristic(ROC)curve and area under curve(AUC)were used to analyze the diagnostic value of serum miR-186-5p and miR-942-5p in glioma.Kaplan-Meier survival curve was used to analyze the re-lationship between serum miR-186-5p and miR-942-5p expression and prognosis of patients.Results The ex-pression level of serum miR-186-5p in monitored group was lower than that in the control group(P＜0.05),and the expression level of miR-942-5p was higher than that in the control group(P＜0.05).The AUC of ser-um miR-186-5p and miR-942-5p in the diagnosis of glioma alone and in combination were 0.735,0.809 and 0.895,respectively.There were significant differences in the proportion of low miR-186-5p expression and high miR-942-5p expression in serum of patients with different preoperative Karnofsky performance status(KPS)scores,World Health Organization(WHO)grades and local infiltration(P＜0.05).The 2-year surviv-al rate of patients with high expression of miR-186-5p was higher than that of patients with low expression of miR-186-5p(x2=6.455,P=0.011).The 2-year survival rate of patients with high miR-942-5p expression was lower than that of patients with low miR-942-5p expression(x2=9.858,P=0.002).miR-186-5p was a protective factor for mortality in glioma patients(P＜0.05),while miR-942-5p was a risk factor(P＜0.05).Conclusion Serum miR-186-5p expression level decreases and miR-942-5p expression level increases in glioma patients,both of which have certain diagnostic value for the occurrence of glioma.

BACKGROUND:Previous studies have confirmed that Wen-Shen-Tong-Du Decoction can promote the recovery of spinal cord injury by inhibiting pyroptosis of splenic B cells,promoting the phagocytosis of myelin debris by microvascular endothelial cells,affecting the migration and infiltration of microglia,promoting the recovery of damaged neurons,and decreasing neuronal apoptosis after spinal cord injury,but the mechanism of this is still not clear. OBJECTIVE:To investigate the effect of Wen-Shen-Tong-Du Decoction on the triggering receptor expressed on myeloid cells 2(TREM2)and PI3K/Akt signaling pathways in mice following spinal cord injury. METHODS:Thirty-six C57BL/6 mice were selected and randomly divided into a sham-operation group,a model group and a Wen-Shen-Tong-Du Decoction group,with 12 mice in each group.In the model and Wen-Shen-Tong-Du Decoction groups,mouse models of T10 spinal cord injury were prepared by the modified Allen's method.On the 1st day after modeling,the Wen-Shen-Tong-Du Decoction group was given Wen-Shen-Tong-Du Decoction by gavage,and the sham-operation group and the model group were given saline by gavage once a day for 28 days.During the drug administration period,mouse motor function was evaluated by Basso Mouse Scale score and inclined plane test.On the 7th and 28th days after modeling,hematoxylin-eosin staining was used to observe the histopathological changes in the spinal cord tissue of the mice;immunofluorescence double staining was used to detect the protein expression of ionized calcium binding adaptor molecule 1(IBA1)and TREM2;and western blot assay was used to detect the expression of TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2,Bax and Caspase3 in spinal cord tissue. RESULTS AND CONCLUSION:Basso Mouse Scale scores and inclined plane test results indicated that the motor function of the mouse hindlimbs was declined after spinal cord injury,and Wen-Shen-Tong-Du Decoction significantly improved motor function in mice with spinal cord injury.Hematoxylin-eosin staining results revealed that Wen-Shen-Tong-Du Decoction significantly ameliorated the pathological structure of spinal cord tissue compared with the model group,manifesting as reduced degrees of dorsal white matter and neuronal atrophy,decreased cytoplasmic vacuolization,and reduced inflammatory cell infiltration.Immunofluorescence double staining results showed that on the 7th day after modeling,the protein expression of IBA1 and TREM2 in the model group was lower than that in the sham-operation group(P＜0.05),and the protein expression of IBA1 and TREM2 in the Wen-Shen-Tong-Du Decoction group was higher than that in the model group(P＜0.05);on the 28th day after modeling,the protein expression of TREM2 in the model group was lower than that in the sham-operation group(P＜0.05),and the protein expression of TREM2 in the spinal cord tissue of the mice in the Wen-Shen-Tong-Du Decoction group was higher than that in the model group(P＜0.05).Western blot results analysis demonstrated that on the 7th day after modeling,compared with the sham-operation group,the model group exhibited a significant reduction in TREM2,PI3K,and Bcl2/Bax(P＜0.05),as well as a significant increase in p-Akt,Bax and p-Akt/Aktp-PI3K(P＜0.05);compared with the model group,the Wen-Shen-Tong-Du Decoction group showed a significant increase in TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2,p-PI3K/PI3K,p-Akt/Ak,and Bcl2/Bax(P＜0.05),as well as a significant decrease in Bax and Caspase3 protein expression(P＜0.05).On the 28th day after modeling,compared with the sham-operation group,the model group exhibited a significant reduction in TREM2,PI3K,p-PI3K,Akt,p-Akt,Bcl2 and Bcl2/Bax(P＜0.05),as well as a significant increase in Bax protein expression(P＜0.05);compared with the model group,the Wen-Shen-Tong-Du Decoction group showed a significant increase in TREM2,PI3K,Akt,p-Akt,Bcl2,and Bcl2/Bax(P＜0.05),as well as a significant decrease in Bax protein expression(P＜0.05).To conclude,Wen-Shen-Tong-Du Decoction may activate the PI3K/Akt signaling pathway by up-regulating the expression of TREM2 protein in microglia,and then inhibit neuronal apoptosis,thus exerting neuroprotective effects and promoting the repair of spinal cord injury.

Objective:To observe the characteristics of gastrointestinal tract symptoms in patients with Parkinson′s disease (PD) and analyze the characteristics of these symptoms in patients with different PD subtypes.Methods:A total of 297 PD patients who were admitted to the Neurology Department of the Second Affiliated Hospital of Soochow University from November 2022 to March 2024 were enrolled. The gastrointestinal symptoms of PD patients were evaluated using Drooling Severity and Frequency Scale (DSFS), Sialorrhea Clinical Scale for Parkinson′s disease (SCS-PD), Drooling Rating Scale (DRS), Eating Assessment Tool 10 (EAT-10), Gastroparesis Cardinal Symptom Index (GCSI), and Rome Ⅳ diagnostic criteria. The patients were grouped based on the presence or absence of gastrointestinal symptoms. Additionally, they were stratified according to disease duration (≤2 years, 2-5 years, 5-10 years, and>10 years) and motor symptom subtype [tremor-dominant (TD) vs. postural instability and gait difficulty (PIGD)]. One-way ANOVA and logistic regression analysis were applied to examine between-group differences while Spearman correlation analysis was employed to assess correlations between clinical symptoms.Results:The average age of the patients with PD was 67.0 (60.0, 72.0) years, and 161 (54.2%) were male. The incidence of PD combined with gastrointestinal symptoms was, in descending order: constipation (191, 64.3%), salivation (155, 52.2%), gastroparesis (93, 31.3%), and dysphagia (68, 22.9%). Compared with PD patients without gastrointestinal symptoms, those with symptoms had higher scores in the RBD-HK [12.0 (5.0, 21.5) vs. 5.0 (0.0, 9.0), Z=-3.74, P=0.017], ESS [6.0 (2.0, 12.0) vs. 3.0 (0.0, 6.0), Z=-3.20, P=0.023], and MDS-UPDRS Part Ⅰ [9.0 (5.0, 14.0) vs. 5.0 (2.3, 9.0), Z=-3.61, P=0.014]. The severity of sialorrhea and deglutition disorders, along with the incidence of constipation, all increased with longer disease duration. Patients with the PIGD subtype had higher GCSI scores than those with the TD subtype [0.0 (0.0, 1.9) vs. 0.0 (0.0, 0.0), Z=-3.57, P=0.007]. Across the cohort, sialorrhea, deglutition disorders, gastroparesis, and constipation were positively associated with the H-Y stage, MDS-UPDRS Ⅰ, HAMD, NMSQ, and SCOPA-AUT; EAT-10 scores were negatively correlated with MoCA ( r=-0.171, P<0.05); and GCSI scores were negatively correlated with MMSE and MoCA ( r=-0.154, r=-0.169, both P<0.05). Conclusions:Overall, 84.5% of the patients with PD had one or more gastrointestinal symptoms, and the incidence and severity of gastrointestinal symptoms increased with disease duration. The severity of gastroparesis was higher in the PIGD group than in the TD group. The scores of all gastrointestinal symptoms were positively correlated with the H-Y stage and MDS-UPDRS Ⅰ, while the GCSI scores were negatively correlated with the cognitive scores.

BACKGROUND:Since entering the intelligent age,there has been a growing enthusiasm for research on artificial intelligence technologies applied to healthcare.In the field of orthopedics,robot-assisted technology is one of the most attractive artificial intelligence technologies.After nearly 40 years of development,robot-assisted technology has gradually matured,and the types of orthopaedic surgeries in which it can be involved have gradually increased and played a crucial role.OBJECTIVE:To summarize the application of orthopedic robots in the clinic and analyze their advantages and disadvantages.METHODS:The PubMed and CNKI databases were searched for relevant literature.The search terms were"robot-assisted technology,surgical robots,orthopaedic robots,robotic arm,orthopaedic,orthopaedic surgery,joint,spine,trauma,bone tumor"in English and Chinese.A total of 82 articles with high relevance were screened according to the inclusion criteria.RESULTS AND CONCLUSION:(1)Robot-assisted technology is now more mature in clinical practice and can be used in most orthopedic surgeries with good clinical performance.(2)The main advantages of orthopedic robots include relieving clinicians'work pressure,reducing intraoperative side injuries,and shortening radiation exposure time.However,there may also be a prolongation of surgical operation time and an increase in postoperative complications.(3)The future development of orthopedic robots will be along the direction of high intelligence,low cost,and faster.
