		                        			Methods:
		                        			Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. 
		                        		
		                        			Results:

		                        			The aim of this study is to explore the mechanism of ligustilide, the main active constituent of essential oils of traditional Chinese medicine Angelicae Sinensis Radix, on alleviating oxygen-glucose deprivation/reperfusion(OGD/R) injury in PC12 cells from the perspective of ferroptosis. OGD/R was induced in vitro, and 12 h after ligustilide addition during reperfusion, cell viability was detected by cell counting kit-8(CCK-8) assay. DCFH-DA staining was used to detect the level of intracellular reactive oxygen species(ROS). Western blot was employed to detect the expression of ferroptosis-related proteins, glutathione peroxidase 4(GPX4), transferrin receptor 1(TFR1), and solute carrier family 7 member 11(SLC7A11), and ferritinophagy-related proteins, nuclear receptor coactivator 4(NCOA4), ferritin heavy chain 1(FTH1), and microtubule-associated protein 1 light chain 3(LC3). The fluorescence intensity of LC3 protein was analyzed by immunofluorescence staining. The content of glutathione(GSH), malondialdehyde(MDA), and Fe was detected by chemiluminescent immunoassay. The effect of ligustilide on ferroptosis was observed by overexpression of NCOA4 gene. The results showed that ligustilide increased the viability of PC12 cells damaged by OGD/R, inhibited the release of ROS, reduced the content of Fe and MDA and the expression of TFR1, NCOA4, and LC3, and improved the content of GSH and the expression of GPX4, SLC7A11, and FTH1 compared with OGD/R group. After overexpression of the key protein NCOA4 in ferritinophagy, the inhibitory effect of ligustilide on ferroptosis was partially reversed, indicating that ligustilide may alleviate OGD/R injury of PC12 cells by blocking ferritinophagy and then inhibiting ferroptosis. The mechanism by which ligustilide reduced OGD/R injury in PC12 cells is that it suppressed the ferroptosis involved in ferritinophagy.

		                        			BACKGROUND:
		                        			Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.
		                        		
		                        			METHODS:
		                        			In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.
		                        		
		                        			RESULTS:
		                        			81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.
		                        		
		                        			CONCLUSIONS
		                        			In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

		                        			OBJECTIVE:
		                        			To derive the Chinese medicine (CM) syndrome classification and subgroup syndrome characteristics of ischemic stroke patients.
		                        		
		                        			METHODS:
		                        			By extracting the CM clinical electronic medical records (EMRs) of 7,170 hospitalized patients with ischemic stroke from 2016 to 2018 at Weifang Hospital of Traditional Chinese Medicine, Shandong Province, China, a patient similarity network (PSN) was constructed based on the symptomatic phenotype of the patients. Thereafter the efficient community detection method BGLL was used to identify subgroups of patients. Finally, subgroups with a large number of cases were selected to analyze the specific manifestations of clinical symptoms and CM syndromes in each subgroup.
		                        		
		                        			RESULTS:
		                        			Seven main subgroups of patients with specific symptom characteristics were identified, including M3, M2, M1, M5, M0, M29 and M4. M3 and M0 subgroups had prominent posterior circulatory symptoms, while M3 was associated with autonomic disorders, and M4 manifested as anxiety; M2 and M4 had motor and motor coordination disorders; M1 had sensory disorders; M5 had more obvious lung infections; M29 had a disorder of consciousness. The specificity of CM syndromes of each subgroup was as follows. M3, M2, M1, M0, M29 and M4 all had the same syndrome as wind phlegm pattern; M3 and M0 both showed hyperactivity of Gan (Liver) yang pattern; M2 and M29 had similar syndromes, which corresponded to intertwined phlegm and blood stasis pattern and phlegm-stasis obstructing meridians pattern, respectively. The manifestations of CM syndromes often appeared in a combination of 2 or more syndrome elements. The most common combination of these 7 subgroups was wind-phlegm. The 7 subgroups of CM syndrome elements were specifically manifested as pathogenic wind, pathogenic phlegm, and deficiency pathogens.
		                        		
		                        			CONCLUSIONS
		                        			There were 7 main symptom similarity-based subgroups in ischemic stroke patients, and their specific characteristics were obvious. The main syndromes were wind phlegm pattern and hyperactivity of Gan yang pattern.

		                        			Objective: To analyze the course of disease and epidemiological parameters of COVID-19 and provide evidence for making prevention and control strategies. Methods: To display the distribution of course of disease of the infectors who had close contacts with COVID-19 cases from January 1 to March 15, 2020 in Guangdong Provincial, the models of Lognormal, Weibull and gamma distribution were applied. A descriptive analysis was conducted on the basic characteristics and epidemiological parameters of course of disease. Results: In total, 515 of 11 580 close contacts were infected, with an attack rate about 4.4%, including 449 confirmed cases and 66 asymptomatic cases. Lognormal distribution was fitting best for latent period, incubation period, pre-symptomatic infection period of confirmed cases and infection period of asymptomatic cases; Gamma distribution was fitting best for infectious period and clinical symptom period of confirmed cases; Weibull distribution was fitting best for latent period of asymptomatic cases. The latent period, incubation period, pre-symptomatic infection period, infectious period and clinical symptoms period of confirmed cases were 4.50 (95%CI:3.86-5.13) days, 5.12 (95%CI:4.63-5.62) days, 0.87 (95%CI:0.67-1.07) days, 11.89 (95%CI:9.81-13.98) days and 22.00 (95%CI:21.24-22.77) days, respectively. The latent period and infectious period of asymptomatic cases were 8.88 (95%CI:6.89-10.86) days and 6.18 (95%CI:1.89-10.47) days, respectively.

		                        			ObjectiveTo observe the effect of Liuwei Dihuangtang (LWDHT) on depression-like behaviors of rats with diabetes mellitus and depression (DD) and explore its mechanism. MethodThe diabetes mellitus (DM) model was induced by the high-fat diet and tail vein injection of low-dose streptozotocin (STZ) in 50 male Sprague-Dawley rats of SPF grade. Then the DD model was induced by chronic unpredictable mild stress (CUMS) for 28 days in DM rats. Fifty DD rats were randomly divided into model group, fluoxetine group (10 mg·kg-1·d-1), and low-, medium-, and high-dose LWDHT groups (3.375, 6.75, 13.5 g·kg-1·d-1), with 10 rats in each group. Another 10 healthy rats were assigned into a control group and received normal saline by gavage. After four weeks of drug intervention, the forced swimming assay was carried out to assess the depression-like behaviors of rats. The expression levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-4 (IL-4), and interleukin-10 (IL-10) in the anterior cingulate cortex (ACC) were detected by enzyme-linked immunosorbent assay (ELISA). Immunofluorescence was used to detect the expression of myelin basic protein (MBP) in ACC and the co-localization of ionized calcium-binding adapter molecule 1 (Iba1) with intracellular microtubule-associated protein 1 light chain 3 (LC3). The protein expression levels of MBP, myelin proteolipid protein (PLP), myelin oligodendrocyte glycoprotein (MOG), Beclin-1, LC3, p62, and microglia (MG) phenotypic protein-related inducible nitric oxide synthase (iNOS), and arginase 1 (Arg1) were detected by Western blot. ResultCompared with the control group, the model group showed shortened swimming time and prolonged immobility time (P<0.01). Compared with the model group, the medium- and high-dose LWDHT groups showed reduced immobility time (P<0.05, P<0.01). Compared with the control group, the model group showed decreased protein expression of MBP, PLP, and MOG in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated protein expression of MBP, PLP, and MOG (P<0.05, P<0.01). Compared with the control group, the model group showed decreased MBP fluorescence intensity in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed increased MBP fluorescence intensity in the ACC region (P<0.05, P<0.01). Compared with the control group, the model group showed increased expression of iNOS (P<0.01) and slightly increased Arg1 protein expression. Compared with the model group, the medium- and high-dose LWDHT groups and the fluoxetine group showed down-regulated iNOS expression and up-regulated Arg1 protein expression (P<0.05, P<0.01), but there was no significant difference between the fluoxetine group and the medium-,high-dose LWDHT groups. Compared with the control group, the model group showed increased expression levels of proinflammatory factors IL-1β and TNF-α in the ACC region (P<0.01) and slightly increased expression levels of anti-inflammatory factors IL-4 and IL-10. Compared with the model group, the fluoxetine group, and the medium- and high-dose LWDHT groups showed down-regulated expression of IL-1β and TNF-α (P<0.05, P<0.01) and up-regulated expression of IL-4 and IL-10 (P<0.05, P<0.01). Compared with the control group, the model group showed reduced expression levels of Beclin-1 and LC3Ⅱ (P<0.01) and increased expression level of p62 (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed up-regulated Beclin-1 and LC3Ⅱ expression (P<0.01) and down-regulated p62 expression (P<0.01). Compared with the control group, the model group showed decreased LC3+Iba1+ cells in the ACC region (P<0.01). Compared with the model group, the fluoxetine group and the medium- and high-dose LWDHT groups showed increased LC3+Iba1+ cells (P<0.05, P<0.01). ConclusionLWDHT can alleviate the depression-like behaviors in DD rats presumedly by promoting MG autophagy, regulating MG phenotypic changes, and increasing MG clearance of myelin sheath fragments. Meanwhile, MG phenotypic transformation also inhibits ACC inflammation in DD rats, improves the local microenvironment of oligodendrocyte proliferation and differentiation, and ultimately promotes the repair and remyelination of damaged myelin sheath.

		                        			ObjectiveTo observe the effect of Liuwei Dihuangtang on depression-like behavior of diabetes mellitus combined with comorbid depression (DD) rats, so as to explore its action mechanism. MethodFifty male SD rats of SPF grade were fed with high fat diet and injected with low-dose streptozotocin (STZ) via tail vein for inducing diabetes. Afterwards, the diabetic rats were exposed to chronic unpredictable mild stress (CUMS) for 28 d. The successfully modeled DD rats were randomly divided into five groups: model group, fluoxetine (10 mg·kg-1·d-1) group, and low-, medium-, and high-dose (3.375, 6.75, 13.5 g·kg-1·d-1) Liuwei Dihuangtang groups, with 10 in each group. Another 10 rats were classified into the normal control group and treated with intragastric administration of normal saline for four weeks. The tail suspension test and open field test were conducted to evaluate the depressive-like phenotype of rats. The contents of malondialdehyde (MDA), reactive oxygen species (ROS), 8-hydroxy-2 deoxyguanosine (8-OHdG), superoxide dismutase (SOD), and glutathione (GSH) in ventral hippocampus (vHIP) were measured by enzyme-linked immunosorbent assay (ELISA), and the myelin basic protein (MBP) expression in vHIP by immunofluorescence assay. The expression levels of MBP, myelin protein lipoprotein (PLP), myelin oligodendrocyte glycoprotein (MOG), phosphorylated adenosine 5'-monophosphate-activated protein kinase (p-AMPK)/AMPK, phosphorylated protein kinase B (p-Akt)/Akt, phosphorylated glycogen synthase kinase 3β (p-GSK3β)/GSK3β, and nuclear factor erythroid-2 related factor 2(Nrf2) were determined by Western blotting. ResultCompared with the normal control group, the model group exhibited significantly prolonged immobility in the tail suspension test (P<0.01) and shortened residence at the central area in the open field test (P<0.01). The immobility time in the medium- and high-dose Liuwei Dihuangtang groups declined to different degrees as compared with that of the model group (P<0.01), while the residence time at the central area was significantly increased (P<0.05, P<0.01). Compared with the normal control group, the model group displayed down-regulated MBP, PLP, and MOG protein expression in vHIP (P<0.01). Compared with the model group, Liuwei Dihuangtang at the low dose up-regulated the expression of MBP (P<0.05), but did not obviously affect the expression of MOG and PLP. Fluoxetine and Liuwei Dihuangtang at the medium and high doses up-regulated the expression of MBP, PLP, and MOG (P<0.05, P<0.01). Comparison with the normal control group revealed that the MBP fluorescence intensity in vHIP of the model group was significantly weakened (P<0.01). After the intervention, the MBP fluorescence intensities in the medium- and high-dose Liuwei Dihuangtang groups and fluoxetine group were enhanced in contrast to that of the model group (P<0.05, P<0.01). SOD and GSH in the model group were lower than those in the normal control group (P<0.01), whereas the MDA, ROS, and 8-OHdG expression levels were higher (P<0.01). Compared with the model group, Liuwei Dihuangtang at the medium and high doses and fluoxetine all down-regulated the expression levels of MDA, ROS, and 8-OHdG (P<0.05,P<0.01), while up-regulated SOD and GSH expression (P<0.05,P<0.01). The expression levels of p-AMPK, p-Akt, and Nrf2 in the model group were down-regulated as compared with those in the control group, and the expression of p-GSK3β was up-regulated (P <0.01). As demonstrated by comparison with the model group, the protein expression of p-AMPK in the low-dose Liuwei Dihuangtang group was elevated (P<0.05), while p-Akt and Nrf2 were slightly increased, exhibiting no statistical significant difference. However, the protein expression levels of p-AMPK, p-Akt, and Nrf2 in the medium- and high-dose Liuwei Dihuangtang groups and fluoxetine group were up-regulated, while those of p-GSK3β were down-regulated (P<0.05,P<0.01). ConclusionLiuwei Dihuangtang improves the depressive-like behavior of DD rats, which may be related to its activation of the AMPK/Akt/GSK3β/NRF2 pathway, regulation of the oxidative stress in vHIP, and enhancement of myelin repair.
