Background: To compare and rank the clinical effects of different acupuncture and acupuncture-related therapies on patients with poststroke cognitive impairment. Methods: We evaluated the direct and indirect evidence from relevant studies using network meta-analysis. Eight databases were examined in order to find randomized controlled trials of acupuncture-related therapies for individuals with poststroke cognitive impairment. After 2 researchers independently scanned the literature, extracted the data, and assessed the risk of bias in the included studies, the data were analyzed using RevMan5.4, Stata15.0, and WinBUGS1.4.3 software. Results: We assess the benefits and drawbacks of various acupuncture-related therapies, rank the efficacy of various acupuncture-related therapies in the treatment of poststroke cognitive impairment, and describe the best acupuncture intervention approaches or combinations based on the available data. Conclusion: This study will contribute to the existence of data on the safety and efficacy of acupuncture-related therapies in the treatment of poststroke cognitive impairment, and it may aid clinical guideline makers in selecting the best acupuncture treatment for poststroke cognitive impairment.

Postpartum cerebral arterial dissections are rare, and the clinical features, diagnosis, and treatment approaches are not clear to many physicians. This study was to investigate the clinical features, diagnosis, and treatment of postpartum cerebral arterial dissections.One patient with postpartum cerebral arterial dissections enrolled in our hospital was analyzed. All patients with postpartum cerebral arterial dissections retrieved from the PubMed were also included in this study and analyzed.A total of 45 patients with postpartum cerebral arterial dissections were retrieved including our case, with an age range of 24 to 44 years (mean 34). Thirty-six (80%) patients were older than 30 years of age (mean 35). There were 17 cases of cesarean section, 14 cases of natural labor, and 14 cases whose delivery modes were not reported. The clinical symptoms included headache in 35 cases (78%) and neck pain in 14 (31%). The symptoms occurred at a mean time of 11 days (range 0-53 days) following delivery. Among 45 patients, arterial dissections involved unilateral carotid or vertebral artery in 29 cases (64%), bilateral carotid or vertebral arteries in 8 (18%), 3 arteries in 3 (7%), and all bilateral carotid and vertebral arteries in 5 (11%). Fourteen (31%) patients were treated with antiplatelet agents, 27 (60%) with anticoagulation, 7 (16%) with both antiplatelet and anticoagulation medications, and only 2 (4%) with stent angioplasty. The prognosis was complete recovery in 30 (86%) patients and mild focal neurological symptoms in 5 (14%).Postpartum cerebral arterial dissections are rare, and correct diagnosis relies on imaging examination. Prognosis is usually favorable in patients with early diagnosis and prompt treatment.
