Objective:To explore the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in ruptured anterior communicating wide-necked aneurysms.Methods:Thirty-two patients with ruptured anterior communicating wide-necked aneurysms accepted Neuroform Atlas stent assisted coil embolization in Department of Neurosurgery, People's Hospital Affiliated to Shandong First Medical University from January 2022 to June 2023 were chosen. DSA was performed immediately after surgery, and aneurysm embolization was assessed using Raymond grading. Prognoses were assessed by modified Rankin Scale (mRS, mRS scores≤2 as good prognosis and mRS scores>2 as poor prognosis) at last follow-up. DSA was performed again 6 months after surgery to assess the aneurysm healingResults:Neuroform Atlas stents were successfully implanted in all 32 patients; Postoperative DSA showed that aneurysm embolization reached Raymond grading I in all 32 patients(100%). No such complications as in-stent thrombosis, cerebral vasospasm, or poor opening of the stent were noted excepted for one with intraoperative aneurysm rupture hemorrhage. At the last follow-up, 31 patients had good prognosis and 1 had poor prognosis; in 22 patients underwent DSA re-examination, Raymond grading I was noted in 20 patients (90.91%) and grading II in 2 (9.09%).Conclusion:Neuroform Atlas stent-assisted coil embolization for ruptured anterior communicating wide-necked aneurysms seems safe and effective.

Postoperative complications are the third leading cause of death worldwide,and failure to intervene in time can lead to serious consequences.Despite the continuous improvement in medical level in recent years,the incidences of postoperative acute pain,postoperative nausea and vomiting,postoperative urinary retention,and perioperative neurocognitive disorders are still high.Numerous studies have shown that acupuncture during the perioperative period can not only reduce preoperative anxi-ety and relieve postoperative pain but also reduce the incidence of postoperative nausea and vomiting.Acupuncture,a safe and ef-fective clinical therapy,is associated with few adverse reactions;thus,it has attracted increased attention from physicians and has been fully used in various clinical settings.However,at present,the specific mechanism by which acupuncture exerts the above effects is not clear,which limits its use to a certain extent.This article reviews the research progress of acupuncture in the treat-ment of postoperative acute pain and the prevention of various postoperative complications,as well as related mechanisms.

Objective:To establish UPLC fingerprint method and 2 contents determination methods of Buddleja officinalis; To provide a reference for improving the quality control standard and evaluation of Buddleja officinalis from different habitats.Methods:UPLC method was used to establish the fingerprints of 17 batches of Buddleja officinalis. The similarity evaluation, clustering analysis, principal component analysis and orthogonal partial least squares discriminant analysis were used to compare the quality differences of Buddleja officinalis from different habitats.

Objective:To establish the ultra-high performance liquid chromatography (UPLC) fingerprint and high performance liquid chromatography (HPLC) content determination method of Curcumae Radix standard decoction; To predict the quality markers of Curcumae Radix standard decoction combined with network pharmacology.Methods:UPLC method was used to establish the fingerprint of Curcumae Radix standard decoction, and the common peaks were determined. Combined with chemical pattern recognition techniques such as similarity analysis and clustering analysis, Curcumae Radix standard decoction from different producing areas was studied, and curcumol was used as an index to determine the content of 24 batches of Curcumae Radix standard decoction. At the same time, network pharmacology was used to predict potential of curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one.Results:A total of 24 batches of Curcumae Radix standard decoction from different habitats were compared and analyzed, and 10 common peaks were calibrated. The similarity of 24 batches of samples ranged from 0.982 to 0.999. Clustering analysis and principal component analysis divided them into three categories. Heat map analysis showed that peak 8 (curcumol) and peak 9 ((1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one) were the main components. The content of curcumol in 24 batches of Curcumae Radix standard decoction was 0.69-1.87 mg/g; curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β- (3-oxobutyl) bicyclo [4.1.0] heptan-3-one may regulate the neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation by regulating neuroactive ligand-receptor interaction signaling pathway, calcium signaling, and excitation. It was preliminarily predicted that curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one were potential quality markers of Curcumae Radix.Conclusion:Curcumol and (1S, 6β)-1β-Methyl-4-(1-methylethylidene)-7β-(3-oxobutyl) bicyclo [4.1.0] heptan-3-one are potential quality markers of Curcumae Radix standard decoction, and the established fingerprint can be used for the quality control of Curcumae Radix standard decoction.

Objective Space radiation is an important environmental factor affecting the health and efficiency of astronauts.To explore the effects of radiation on electroencephalogram(EEG)signal,and to provide references for further study of the effects of radiation on Central Nervous System(brain)injury.Methods The resting state EEG of radiotherapy volunteers were collected before and after X-ray exposure.The effects of radiation on EEG was studied by means of spectral analysis,nonlinear dynamic characteristic analysis,correlation coefficient analysis and microstate analysis.Results The results show that radiation induced a"slow wave"phenomenon in the EEG spectrum,with a decrease in Gravity Frequency,Sample Entropy,and Lempel-Ziv Complexity,and an increase in Fatigue Index.The average duration and frequency of EEG microstate C both significantly decreased,and the proportion of time for microstate D decreased,while the average correlation coefficient between microstates A and C increased.Conclusion A decrease was induced by radiation in neuronal excitability,which may affect cognitive brain networks and brain attention.This study can provide reference for the study of radiation damage to the Central Nervous System(brain).

OBJECTIVE: To explore the clinical and genetic characteristics of three children with KBG syndrome. METHODS: Clinical data of the three children from two families who have presented at the First Affiliated Hospital of Zhengzhou University between October 2019 and September 2020 and their family members were collected. Trio-whole exome sequencing (trio-WES) and Sanger sequencing were carried out. RESULTS: All children had feeding difficulties, congenital heart defects and facial dysmorphism. The sib- pair from family 1 was found to harbor a novel de novo heterozygous c.6270delT (p.Q2091Rfs*84) variant of the ANKRD11 gene, whilst the child from family 2 was found to harbor a novel heterozygous c.6858delC (p.D2286Efs*51) variant of the ANKRD11 gene, which was inherited from his mother who had a mild clinical phenotype. CONCLUSION The heterozygous frameshift variants of the ANKRD11 gene probably underlay the disease in the three children. Above findings have enriched the spectrum of the ANKRD11 gene variants.

Objective:To evaluate the effect of electroacupuncture (EA) on programmed cell death ligand-1 (PD-L1)/programmed cell death receptor-1 (PD-1)/Src-homology region two domain-containing phosphatase-1 (SHP-1) signaling pathway in the dorsal root ganglia (DRG) of rats with acute postoperative pain.Methods:Thirty-nine SPF male Sprague-Dawley rats, weighing 220-250 g, aged 6-8 weeks, were divided into 3 groups ( n=13 each) using a random number table method: control group (group C), abdominal surgery group (group S) and abdominal surgery+ EA group (group S+ EA). Group S and group S+ EA underwent abdominal surgery under isoflurane anesthesia. In S+ EA group, both Zusanli and Sanyinjiao acupoints were selected and stimulated for 30 min with a frequency of 10 Hz continuous wave and a current of 1 mA starting from the end of operation and 2 h after operation. Seven rats were selected from each group for measurement of the mechanical paw withdrawal threshold (MWT), abdominal contraction threshold (ACT), thermal paw withdrawal latency (TWL) and cold paw withdrawal latency (CWL) at 1 day before developing the model (T 0) and 3, 5, 7, 9, 11 and 24 h after developing the model (T 1-6). Six rats in each group were sacrificed at 5 h after the model was prepared, and T 12-L 4 DRG was removed for determination of the expression of interleukin-6 (IL-6), PD-L1, PD-1 and SHP-1 (by Western blot) and expression of PD-L1 in various neurons (by immunofluorescence). Results:There was no significant difference in TWL and CWL between the three groups at different time points ( P>0.05). Compared with group C, MWT at T 1-5 and ACT at T 1-6 were significantly decreased, and the expression of IL-6 in DRG was up-regulated, and the expression of PD-L1, PD-1 and SHP-1 in DRG was down-regulated in group S ( P<0.05). Compared with group S, MWT and ACT were significantly increased at T 1, 2, the expression of IL-6 in DRG was down-regulated, and the expression of PD-L1, PD-1 and SHP-1 in DRG was up-regulated in group S+ EA ( P<0.05). The results of immunofluorescence showed that PD-L1 was expressed on both small diameter neurons (CGRP + neurons and IB4 + neurons) and large diameter neurons (NF200 + neurons) and mainly on CGRP + neurons and IB4 + neurons. There was no significant difference in the expression of PD-L1 in various DRG neurons among the three groups ( P>0.05). Conclusions:The mechanism by which EA relieves acute postoperative pain may be related to activation of the PD-L1/PD-1-SHP-1 signaling pathway in the DRG of rats.

A 58-year-old female patient presented with painful and itchy skin lesions on the head, neck, chest and back for 20 days, and was admitted to the hospital in February 2010. The skin lesions manifested as superficial erosions on an erythematous base with positive Nikolsky′s sign. Histopathological examination showed fissures above the granular and spinous cell layers, and scattered dyskeratotic cells. Direct immunofluorescence (DIF) assay revealed IgG and C3 deposits between spinous cells. The patient was initially diagnosed with pemphigus foliaceus. After the treatment with triamcinolone (24 mg/d) , tripterygium glycosides (60 mg/d) , nicotinamide (300 mg/d) and tetracycline (2 g/d) , skin lesions gradually subsided. In June 2017, the patient was readmitted due to itchy skin lesions on the head, neck, chest, back and hands for 15 days, which manifested as tense bullae on an erythematous base with negative Nikolsky′s sign. Histopathological examination showed subepidermal blisters and infiltration of eosinophils and lymphocytes in the blisters and superficial dermis, DIF assay revealed the deposition of IgG and C3 along the basement membrane zone, and enzyme-linked immunosorbent assay showed positive results for anti-BP180 antibody but negative results for anti-Dsg1 and Dsg3 antibodies. Then, a diagnosis of bullous pemphigoid was confirmed. The patient was treated with oral triamcinolone (12 mg/d) , nicotinamide (300 mg/d) and tetracycline (2 g/d) , and the lesions rapidly subsided.

OBJECTIVE: To assess the diagnostic value of copy number variation sequencing (CNV-seq) in the genetic etiology of fetuses with nasal bone dysplasia (NBD). METHODS: A total of 217 fetuses discovered with NBD from December 2017 to December 2020 were divided into the isolated NBD group and NBD combined with other anomalies group, for which copy number variations (CNVs) were analyzed. RESULTS: A total of 40 fetal abnormalities were detected in 217 cases, with an overall abnormal rate of 18.4%. These included 31 cases with aneuploidies (14.3%, 31/217) and 9 cases with genomic CNVs (4.1%, 9/217). Five cases of trisomy 21 (3.5%, 5/144) and two CNVs cases with unknown clinical significance (1.4%, 2/144) were detected in the isolated group. As for the combined NBD group, 26 aneuploidies (35.6%, 26/73), including 19 cases with trisomy 21, 6 cases with trisomy 18, 1 case with trisomy 13, 5 cases with pathogenic CNVs (6.8%, 5/73), and 2 cases with CNVs of unknown clinical significance (2.7%, 2/73) were detected. A significant difference was detected between the two groups (P < 0.01). CONCLUSION The detection rate of CNV-seq is high for chromosomal aneuploidies and pathogenic CNVs in fetuses with NBD, particularly in those combined with other ultrasonic abnormalities.
