Ischemic stroke is a common cerebrovascular disease, characterized by hypoxia and nutritional deficiency in local brain tissue due to insufficient blood supply. Angiogenesis, the formation of new vascular networks on the basis of existing blood vessels, is of great significance for increasing blood flow in the ischemic area of brain tissue, restoring blood and oxygen supply, and improving disease prognosis. This complex process is regulated by various factors, including cytokines, growth factors, and signaling pathways. Among these, the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is considered a key regulatory pathway. It not only plays an important role in anti-apoptosis and promoting cell survival, but also regulates cell growth, differentiation, migration, and survival, while deeply participating in the regulation of angiogenesis. Chinese medicine offers unique advantages with its multi-component, multi-target, and multi-pathway approach in the treatment of stroke, showing significant potential in treating ischemic stroke. In recent years, it has been found that Chinese medicine can promote angiogenesis after ischemic stroke through the PI3K/Akt signaling pathway. This paper focuses on the PI3K/Akt signaling pathway as the research entry point, and explores in-depth the mechanisms by which Chinese medicine monomers, active components, extracts, derivatives, drug pairs, and Chinese medicine compounds promote angiogenesis after ischemic stroke. The research discusses the regulation of microRNAs (miRNA), endothelial progenitor cells (EPCs), apoptosis, upstream pro-angiogenic factors, and downstream target molecules. The paper also elaborates on related research progress, aiming to reveal how Chinese medicine can exert its potential utility in ischemic stroke treatment through this key signaling pathway, providing a theoretical basis for clinical treatment.

Chronic exertional compartment syndrome (CECS) of the lower extremities is a common clinical condition characterized by exercise-induced pain in the extremities, which is predominantly observed in people who take an active part in sports, such as athletes. It is mainly presented as post-exercise pain in the lower extremities, probably accompanied by numbness and limb weakness, etc., affecting the patients′ life and work. The symptoms of CECS in the lower limbs are usually present after physical activities of a certain intensity, making them difficult to be identified through routine outpatient physical examination, and likely to be misdiagnosed and underdiagnosed. Furthermore, the absence of universally accepted and unified treatment standards for CECS of the lower extremities complicates the decision-making process regarding the necessity of surgical intervention and choice of surgical approach in the clinical practice. For this purpose, recent developments in the diagnosis and treatment of CECS of the lower extremities were reviewed to provide reference for its standardized diagnosis and treatment.

Objective:To investigate the efficacy and prognosis of rituximab (RTX) in the treatment of M-type phospholipase A2 receptor (PLA2R)-associated idiopathic membranous nephropathy (IMN).Methods:It was a retrospective cohort study. The clinical data of PLA2R-associated IMN patients who received RTX treatment in the Shenzhen Second People's Hospital from September 2018 to March 2023 were collected. According to remission status of proteinuria, the patients were divided into proteinuria remission group (24-hour urinary protein quantity < 3.5 g) and non-proteinuria remission group (24-hour urinary protein quantity ≥ 3.5 g), and the clinical data between the two groups were compared. According to baseline 24-hour urinary protein quantity and estimated glomerular filtration rate (eGFR), the patients were divided into high-risk disease progression group [24-hour urinary protein quantity ≥ 8 g or eGFR < 60 ml·min -1·(1.73 m 2) -1] and non-high-risk disease progression group [24-hour urinary protein quantity < 8 g or eGFR ≥ 60 ml·min -1·(1.73 m 2) -1]. Kaplan-Meier survival curve was utilized to compare the differences of proteinuria remission rates and renal composite endpoint event survival rates between the two groups. Multivariate Cox regression analysis was utilized to identify the influencing factors of proteinuria remission and renal composite endpoint event. Results:This study included 46 PLA2R-associated IMN patients, with 31 males (67.4%). The baseline eGFR was (78.4±34.1) ml·min -1·(1.73 m 2) -1. The 24-hour urinary protein quantity was 8.33 (6.04, 12.85) g. After 14.95 (7.44, 22.15) months of follow-up, 29 patients (63.0%) achieved proteinuria remission, with remission time of 6.0 (5.0, 9.0) months. Six (20.7%) patients relapsed, with relapsed time of 17.25 (11.75, 18.28) months. CD20 in the proteinuria remission group was lower than that in the non-proteinuria remission group ( Z=2.270, P=0.023). Eleven (23.9%) patients experienced renal composite endpoint events wtih occurrence time of 16.07 (7.87, 29.63) months. Kaplan-Meier survival curve analysis indicated that there was no statistically significant difference in proteinuria remission rates (log-rank χ2=0.26, P=0.612) and renal composite endpoint event survival rates (log-rank χ2=0.25, P=0.619) between baseline 24-hour urinary protein quantity ≥ 8 g and < 8 g groups. There was no statistically significant difference in proteinuria remission rates after RTX treatment (log-rank χ2=0.77, P=0.381) and renal composite endpoint event survival rates (log-rank χ2=1.41, P=0.236) between eGFR ≥ 60 ml·min -1·(1.73 m 2) -1 and < 60 ml·min -1·(1.73 m 2) -1 groups. Multivariate Cox regression analysis showed that hypertension history ( HR=0.16, 95% CI 0.05-0.55), immunosuppressive therapy history ( HR=0.08, 95% CI 0.01-0.50), baseline eGFR < 60 ml·min -1·(1.73 m 2) -1 ( HR=0.21, 95% CI 0.05-0.92), baseline PLA2R antibody titer ≥ 100 RU/ml ( HR=0.20, 95% CI 0.06-0.69), long time between treatment and first diagnosis ( HR=1.33, 95% CI 1.12-1.57), high baseline triglyceride ( HR=1.46, 95% CI 1.02-2.08), and baseline 24-hour urinary protein quantity ≥ 8 g ( HR=8.54, 95% CI 2.08-35.12) were independent influencing factors of proteinuria remission after RTX treatment. The baseline PLA2R antibody titer ≥ 100 RU/ml was an independent influencing factor of reaching the renal composite endpoint event ( HR=7.31, 95% CI 1.23-43.62). Conclusions:The proteinuria remission rate after RTX treatment of PLA2R-associated IMN is 63.0% and the recurrence rate is 20.7%. The incidence rate of renal composite endpoint event is 23.9%. The hypertension history, immunosuppressant medication history, baseline eGFR < 60 ml·min -1·(1.73 m 2) -1, baseline PLA2R antibody titer ≥ 100 RU/ml, long time between treatment and first diagnosis, high baseline triglyceride, and baseline 24-hour urinary protein quantity ≥ 8 g are independent influencing factors of proteinuria remission, and baseline PLA2R antibody titer ≥ 100 RU/ml is an independent risk factor of renal poor prognosis in PLA2R-associated IMN patients.

Objective To investigate the effect of electroacupuncture preconditioning on microglia polarization in rats after cerebral ischemia reperfusion(IR)injury and explore the role of tyrosine kinase 2(J AK2)/signal transducer and activator of transcription 3(STAT3)pathway in the process.Methods Forty-five clean-grade healthy male Sprague-Dawley rats were randomly and equally divided into sham operation group,IR group and electroacupuncture preconditioning group.Rat model of IR injury was induced with thread occlusion of the internal carotid artery.Before modeling,electroacupuncture preconditioning was applied to Baihui acupoint for 5 consec-utive days in the preconditioning group,and exposure of the cervical blood vessels were inflicted in the sham-operation group.At 24 h after reperfusion,the severity of neurological deficit was observed by modified neurological deficit score(mNSS),and the cerebral infarct volume was observed by TTC staining.Western blotting was used to detect the protein levels of classical acti-vated type(M1)marker inducible nitric oxide synthase(iNOS),alternative activated type(M2)marker arginase 1(Arg-1),JAK2 and p-JAK2,and STAT3 and p-STAT3,and q-PCR was applied to detect the mRNA expression of iNOS and Arg-1.The expression of TNF-α and IL-10 was measured by ELISA.Results Compared with the sham operation group,the mNSS,infarct vol-ume,protein levels of p-JAK2/JAK2,p-STAT3/STAT3,protein and mRNA levels of iNOS and Arg-1,and expression of TNF-α and IL-10 were significantly increased in the IR and electroacu-puncture preconditioning groups(P<0.01).The preconditioning group had obviously lower mNSS,smaller infarct volume,decreased protein levels of p-JAK2/JAK2,p-STAT3/STAT3,re-duced protein and mRNA levels of iNOS,and declined TNF-α expression,but elevated expression of Arg-1 at protein(2.0±0.2 vs 1.5±0.1)and mRNA(4.2±0.8 vs 3.1±0.3)levels and increased IL-10 expression(49.1±7.1 pg/mg vs 27.9±5.9 pg/mg)when compared with the IR group(P<0.01).Conclusion Electroacupuncture preconditioning can promote the polarization of microglia to M2 and inhibit the polarization of microglia to M1 after cerebral IR injury,which may be relat-ed to the inhibition of JAK2/STAT3 pathway.

Objective To evaluate the short-term outcomes of thoracic endovascular aortic repair (TEVAR) with outer branched and inner branched endografts in the treatment of Stanford type B aortic dissection (TBAD), and to analyze the effects of endografts on blood flow status of aortic dissection by computational fluid dynamics (CFD). Methods The clinical data of TBAD patients treated with outer branched endograft technology in outer branched endograft group and inner branched endograft technology in inner branched endograft group in Department of Vascular Surgery Tianjin Medical University General Hospital from May 2018 to December 2021 were collected, and the short-term results of two groups were analyzed retrospectively. Based on CT angiography images of patients in two groups, one typical case in each group was selected to construct personalized 3D model and CFD numerical simulation was performed. The parameters including flow field velocity distribution, wall pressure and wall shear stress (WSS) before and after surgery were compared and analyzed. Results A total of 55 cases with TBAD were enrolled, consisting of 49 cased in outer branched endograft group and 6 cases in inner branched endograft group. There was no statistical difference in baseline data between two groups, and surgical success rate were both 100%. Reconstruction of left subclavical artery(LSA) simple was 41(83.7%) cases in outer branched endograft group and all 6 cases in inner branched endograft group. In outer branched endograft group there were 5 cases with reconstruction of left common carotid artery (LCCA) combined with bridging carotic clavical artery, 2 cases with reconstruction of LCCA combined with LSA embolism, and 1 case with reconstruction of LCCA combined with LSA window. Four cases were lost during follow-up in outer branched endograft group. There were no significant differences in the aorta-related mortality rate (P=1.000), branch patency rate (P=1.000) and avoidance of secondary intervention of target vessels between the two groups during the perioperative period and follow-up period (P=0.298). After endograft implantation of two groups the flow field disturbance in dissection lesions improved significantly, aortic blood flow pattern restored normal, and local abnormally increased WSS decreased. However, the interference of inner branch on aortic arch and blood flow of branch was more obvious than that of outer branch. Conclusions Both outer branched endograft and inner branched endograft TEVAR for reconstruction of LSA had good short-term results in the treatment of TBAD. Compared with inner branched endograft, outer branched endograft has a higher anatomical fit and can restore the normal blood flow to a greater extent for aortic arch.

OBJECTIVE To explore the grouping efficacy of diagnosis related group (DRG) and the influential factors of hospitalization cost in diabetes cases, and to provide theoretical support for improving DRG payment system, reducing medical cost and enhancing the efficiency of medical insurance funds. METHODS The information of 4 368 diabetic patients who were hospitalized in a 3A hospital in Xi’an from January 1, 2021 to June 30, 2023 was retrospectively analyzed, and DRG grouping of them was summarized; the hospitalization costs of patients in different DRG groups were analyzed by using one way ANOVA and Bonferroni multiple comparison. Coefficient of variation (CV) was used for evaluation within the group, and the influential factors of hospitalization costs were analyzed by one-way linear regression analysis and multi-factor linear regression analysis. RESULTS & CONCLUSIONS The CV values of the four DRG groups were all lower than 0.8, indicating good grouping results and good consistency within the group; the difference of hospitalization cost among the four groups was statistically significant (P<0.05), and the hospitalization cost of China Healthcare Security-DRG version 1.1 FW11 group was significantly higher than those of other three groups (P<0.05). Length of stay, drug cost, the number of other diagnoses, test cost and payment method have significant positive effects on the hospitalization cost of diabetic patients. Whether there is pharmacist intervention has a significant negative influence on the hospitalization cost of patients. Under the DRG payment method, medical institutions can consider multidisciplinary linkage and incorporate a variety of management and service tools, including pharmacist’s intervention, to develop refined management measures, to reduce the economic burden of patients’ families and society.
