Comparison of efficacy and safety of direct thrombectomy and bridging thrombectomy in the treat-ment of acute anterior circulation large vessel occlusion stroke under different collateral circulation statuses / 新乡医学院学报

Objective To compare the safety and efficacy of direct thrombectomy versus bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke under different collateral circulation statuses.Methods Totally 93 patients with acute anterior circulation ischemic stroke admitted to the First Affiliated Hospital of Xinxiang Medical University from September 2020 to March 2023 were selected as the research subjects.Patients were divided into direct throm-bectomy group(n=47)and bridging thrombectomy group(n=46)based on the type of thrombectomy.Patients in the direct thrombectomy group received direct intravascular thrombectomy,while patients in the bridging thrombectomy group received intravenous thrombolysis with alteplase combined with mechanical thrombectomy.According computed tomography angiography,the collateral circulation Tan classification was applied to divide the patients into good collateral circulation sub-group and poor collateral circulation sub-group.The modified thrombolysis in cerebral infarction grading(mTICI)was used to evaluate vessel recanalization.Head computed tomography plain scan was performed at 24-48 hours postoperatively to assess if there was hemorrhagic transformation,and modified Rankin Scale score was performed at 90 days postoperatively.Information such as imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,prognosis and spontaneous non-traumatic symptomatic intracerebral hemorrhage(SICH)were collected.Results The age,gender,baseline Alberta stroke program early computed tomography score,baseline national institutes of health stroke scale score,proportions of hypertension,diabetes and atrial fibrillation,baseline systolic pressure,creatinine,baseline blood glucose,platelet count,occlusion site,stroke etiologies and collateral circulation status of patients in the two groups were not statistically significantly different(P＞0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between the two groups(P＞0.05).The hemorrhagic transformation rate of patients in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).There were no significant differences in the post-admission imaging examination time,femoral artery puncture time,vessel recanalization time after thrombectomy,successful vascular reperfusion rate,good prognosis rate,mortality rate,and SICH incidence between patients with good collateral circulation and patients with poor collateral circulation in the two groups(P＞0.05).The hemorrhagic transformation rate of patients with good and poor collateral circulation in the direct thrombectomy group was significantly lower than that in the bridging thrombectomy group(P＜0.05).Conclusion Under different collateral circulation conditions,the safety and efficacy of direct thrombectomy and bridging thrombectomy in the treatment of acute anterior circulation large vessel occlusion stroke are similar,but bridging thrombectomy is more likely to result in cerebral hemorrhage transformation compared with direct thrombectomy.

Effects and mechanism of Setaria italica extract on improving sleep in insomnia mice / 中国药房

OBJECTIVE To investigate the effects of Setaria italica extract on improving insomnia model mice and to explore its potential mechanisms. METHODS The mice were randomly assigned into blank group， model group， positive control group （diazepam， 2.6 mg/kg）， and S. italica extract low-dose， medium-dose and high-dose groups （1.2， 2.4， 4.8 g/kg）， with 10 mice in each group. Except for the blank group， all other groups received intraperitoneal injection of para-chlorophenylalanine （PCPA） to establish the insomnia model. After modeling， the blank group and model group were given a constant volume of normal saline intragastrically， and administration groups were given relevant medicine intragastrically， with a volume of 0.01 mL/g， once a day， for 7 consecutive days. After the administration， the open-field test was conducted to observe the praxiological changes of mice， and to determine the levels of 5-hydroxytryptamine （5-HT） and 5-hydroxyindoleacetic acid （5-HTAA） in the hippocampal tissue， as well as the contents of 5-HT， brain-derived neurotrophic factor （BDNF）， interleukin-2 （IL-2）， IL-6， B-cell lymphoma-2 （Bcl- 2）， and Bcl-2-associated X protein （Bax） in the serum. The expression of phosphoinositide 3-kinase/protein kinase B/nuclear factor- κB （PI3K/Akt/NF-κB） signaling pathway related protein was determined in the hippocampus of mice. RESULTS Compared with the model group， the total exercise time of mice in S. italica extract high-dose group was significantly prolonged， but the total rest time was significantly shortened （P＜0.01）； the number of standing times and modification times were significantly reduced （P＜ 0.01）. The contents of 5-HT， BDNF， and Bcl-2 in serum， and Bcl-2/Bax were significantly increased， while the contents of IL-2， IL-6， and Bax were significantly reduced （P＜0.05 or P＜ 0.01）. The content of 5-HTAA in the hippocampal tissue and 202104010910029）；the phosphorylation levels of PI3K and Akt proteins were increased significantly， while the phosphorylation level of NF-κB p65 protein was decreased significantly （P＜0.05）.CONCLUSIONS High-dose of S. italica extract demonstrates significant therapeutic effects on insomnia in mice， and the mechanism of which may be associated with the regulation of PI3K/Akt/NF-κB signaling pathway.

A follow-up study on the pain changes trend and effects in patients diagnosed with herpes zoster in Beijing City / 中华预防医学杂志

Objective: To understand the changes in pain and its effects in patients with the diagnosis of herpes zoster. Methods: A total of 3 487 patients diagnosed with herpes zoster (HZ) for the first time at the outpatient department of Miyun District Hospital from January 1, 2017, to December 31, 2019, were included in the study. The information of patients was registered and issued with a record card. Patients were required to record the time of pain and rash by themselves. Telephone follow-up was conducted at 21, 90, 180 and 365 days after the onset of rashes, including hospitalization, location of rash and pain, and the time of start and end. The impact of pain on life was evaluated by the Zoster Brief Pain Inventory (ZBPI). Results: The age of 2 999 HZ patients included in the analysis were (53±16) years old, including 1 377 (45.91%) males and 1 903 (63.45%) patients aged 50 years and older. After 21 days of rash, mild, moderate and severe pain accounted for 20.87% (626 cases), 37.98% (1 139 cases) and 33.81% (1 014 cases), respectively. Only 5.07% (152 cases) had no pain or discomfort, and 2.27% (68 cases) had no pain but discomfort. Most of the pain sites were consistent with the rash sites. The chest and back and waist and abdomen were the most common, accounting for 35.58% (1 067 cases) and 29.18% (875 cases), respectively, followed by the limbs and face and neck, accounting for 16.74% (502 cases) and 16.40% (492 cases), respectively. The M (Q1, Q3) of pain days in the HZ patients was 14 (8, 20) days, and the incidence of post-herpetic neuralgia (PHN) was 6.63% (171/2 580) (excluding 419 patients who refused to visit or lost to visit on 90 days after the onset of rash). The pain score of HZ patients within 21 days after the rash was (5.19±2.73) points, and the pain score of PHN patients was (7.61±2.13) points, which was significantly higher than that of non-PHN patients [(5.04±2.69) points] (P<0.001). Daily activities, emotions, walking ability, work, social interaction, sleep and recreation were affected for 21 days after the rash in HZ patients, ranging from 60.79% to 83.83%, with sleep being the most affected (83.83%). The impact scores of pain and life dimensions in PHN patients ranged from 4.59 to 7.61 points on the ZBPI scale, which were higher than those in non-PHN patients (2.49-5.04) (t values ranged from 8.86 to 11.67, all P values <0.001). Conclusion: The proportion of pain in HZ patients after the diagnosis is high, and the pain is more obvious in patients with PHN and HZ patients aged 50 and older, which has a greater impact on their daily lives.
