Objective:To identify the characteristics of research on scalp acupuncture in the treatment of post-stroke cognitive impairment (PSCI).Methods:This was a bibliometric analysis. We selected relevant studies from both Chinese databases (China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and WanFang Data Knowledge Service Platform) and English databases (Web of Science, PubMed, and Scopus) from their inception to December 2023. The CiteSpace software was used to perform visual-based analyses of publication trends, collaborative networks among countries and institutions, author collaboration networks, and research hotspots.Results:We included 730 Chinese studies and 112 English-language studies. From 2004 to 2023, the number of publications on scalp acupuncture for PSCI showed an increasing trend. All Chinese studies were published in China, mainly by universities, and the institutional collaboration density was low (0.002 9). For English-language studies, China had the most publications (103), followed by the USA (7) and Germany (3). Chinese universities were the main publishing institutions, and the density of inter-institutional collaboration (0.183 3) was higher than that for Chinese literature. The density of the author collaboration network was 0.005 0 for Chinese studies and 0.023 8 for English-language studies. In Chinese studies, the most frequent keywords with a centrality greater than 0.1 were cognitive impairment (248 times), stroke (240 times), needling (162 times), cerebral infarction (82 times), and electroacupuncture (80 times). In English-language studies, these were stroke (40 times), cognitive impairment (32 times), acupuncture (15 times), dementia (15 times), ischemic stroke (10 times), and mechanism (7 times). For Chinese studies, the top 3 clusters focused on clinical studies of the effects of scalp acupuncture on PSCI. In English-language studies, the top 4 clusters mainly involved research on the effects and assessment methods of scalp acupuncture for PSCI. The timeline map of keywords in Chinese studies showed that before 2015, the high-frequency keywords were stroke, cognitive impairment, needling, electroacupuncture, scalp acupuncture, body acupuncture, rehabilitation, moxibustion, and clinical research. From 2015 onwards, keywords such as rat, apoptosis, inflammatory factors, mechanism research, signaling pathways, mice, and animal experiments appeared. The timeline map of keywords in English-language studies showed that before 2013, there were few accumulated keywords. After 2013, high-frequency keywords included "multi-infarction rat""computer-based cognitive training""apoptosis""electroacupuncture""mild cognitive impairment""randomized controlled trial""scalp acupuncture""post-stroke cognitive impairment""stroke rehabilitation""systematic review" and "hippocampal CA1 region". In Chinese studies, keywords with high burst intensity included cerebral infarction, acupuncture therapy, vascular, baihui (GV-20), review, learning and memory, and scalp acupuncture. In English-language studies, these included "multi-infarction rat""mild cognitive impairment""electroacupuncture""post-stroke cognitive impairment"and"systematic review".Conclusions:Research in this field has grown rapidly in recent years. Chinese studies focus mainly on the clinical effects of scalp acupuncture for PSCI, while English-language studies focus more on related mechanisms. Furthermore, both Chinese and English-language studies show good consistency in the focus of experimental research, which mainly focuses on the mechanisms of electroacupuncture in the treatment of PSCI.

A 43-year-old female patient with chronic kidney disease stage 5 received a single subcutaneous dose of 60 mg of denosumab for osteoporosis.Prior to treatment,her calcium level was 2.25 mmol·L-1.After 13 days,she experienced numbness in her limbs and mouth corners,as well as muscle spasms.Her blood calcium dropped to 1.12 mmol·L1,and an electrocardiogram revealed a prolonged QT interval.Symptoms improved with intravenous and oral calcium plus active vitamin D treatment,raising her blood calcium to 2.23 mmol·L1.Following discharge from the hospital,the patient continued oral calcium supplementation.However,during the six-month follow-up period,it was observed that the patient still experienced recurrent hypocalcemia.The Naranjo's assessment scale indicated that severe and refractory hypocalcemia was very likely associated with denosumab.This case highlights the importance of vigilance for hypocalcemia in chronic kidney disease patients following denosumab administration,emphasizing the need for thorough pre-medication assessment and post-medication monitoring to ensure patient safety.

Objective To observe the effects of stereotactic implanting depth electrode into the hippocampus on monitoring mesial temporal lobe epilepsy. Methods Thirteen patients with pharmacoresistant epilepsy were included in the present study.The epilcptogenic zone might be located in the hippocampus based on the symptoms and MRI data.Eight-contact depth electrode was implanted into the patients' hippocampus by stereotactic procedures to record the electroencephalogram(EEG).The duration of monitoring lasted for 24-72 hours or more,so as to be sure if the epileptogenic zone was located in the hippocampus,and to provide evidences for surgical resection of epileptic focus.Results Thirteen patients with mesial temporal lobe epilepsy underwent video electroencephalogram monitoring for 72 hours.Twentynine epileptic seizures in 7 patients were detected.Ictal EEG changes manifested as paroxysmal slow wave or spike and slow waves on the background.The epileptiform discharges started from some electrode points,and then propagated to others or the contralateral electrode. After 1-2 seconds of delay,high amplitude slow waves with the frequency of 3-4 Hz were observed on the ipsilateral scalp EEG. Clinical epileptic seizures were not detected in 6 patients during monitoring,depth electrode showed paroxysmal focal high amplitude slow wave or spike and sharp waves,scalp EEG did not find abnormality.Six of thirteen patients received surgical resection of epileptic foci,the outcome during follow-up of 3-8 months was satisfactory.Conclusions To record hippocampal EEG in patients with intractable epilepsy by stereotactic implanting depth electrode into the hippocampus might be a safe and reliable method.It might provide strong evidences for the diagnosis of patients with mesial temporal lobe epilepsy,and for the location of epilcptogenic zone.

Objective To observe the therapeutic effect of minimally invasive evacuation of intracerebral hematoma in dog model of cerebral hemorrhage by using Purdy score, serum levels of neuron-specific-enolase (NSE) and numbers of perihematomal apoptotic cells. Method Twenty dogs were selected to prepoxe the model of cerebral hemorrhage, and they were randomly divided( random number) into minimally invasive treatment group and control group. Minimally invasive procedures were performed to evacuate the hematoma in minimally invasive treatment group in 6 hours after the models were established. The dogs of control group only received medical treatment. Purdy score and serum levels of neuron-specific-enolase were determined on 1,3,5,7 days after the evacuation of the hemotoma and apoptotic cells were counted after the dogs were sacrificed at 7 days after operation. All the results were compared with control group. Purdy score and serum levels of neuron-specific-enolase were compaired with variance analysis of repeated measurement design and apoptotic cells was compared with variance analysis of factorial design,the difference of the two groups showed with q test. P <0.01 showed the difference was significant. Results The Purdy scores in minimally invasive treatment group were 6.3 ± 1.702, 5.8 ± 1. 685,4.2 ± 1.762 and 4.1 ± 1.875 on 1,3,5 and 7 day after evacuation of the hematoma, significant difference was observed as compared with the control group(8.9 ± 1.632, 8.6± 1.342, 7.8±1.335, 7.9±1.468, P <0.01).The serum levels of neuron-specific-enolase were 0.632 ± 0.077, 0.721±0.771, 0.549±0.124 and 0.430 ±0.136 respectively in minimally invasive treatment group, while in the control group were 0.934 ± 0. 064, 0. 997 ±0.075, 0.986 ± 0.042, 0.874 ± 0.165, significant differences in serum levels of neuron-specific-enolase were found between the two groups(P < 0.01). The perihematomal apoptotic cells in minimally invasive treatment group(37.4 cells) was decreased significantly as compared with the control group(88.6 cells), with P < 0.01.Conclusions Minimally invasive procedures for evacuation of intracerbral hematoma might significantly reduce the neurological deficit score and decrease the serum neuron-specific enolase levels and numbers of apeptotic neurons.
