Neurological diseases are common and frequent in clinical practices, which are the main reasons that affect the quality of life and physical and mental health of patients seriously. Tianma Goutengyin (TGY) is from the New Significance of Patterns and Treatment in Miscellaneous Diseases, which was compiled by a famous doctor, HU Guangci. TGY is widely used in clinical practice and has the effects of calming the liver and calming the wind, clearing heat and activating the blood, tranquilization, and nourishing the liver and kidneys. Clinical studies have confirmed that modified TGY can be used either alone or in combination with acupuncture or western medicine to treat dementia, headache, vertigo, hypertension, insomnia, Parkinson's disease, stroke, epilepsy, and other common neurological diseases, with significant curative effect, few side effects, and high safety. The main active constituents of single flavor drugs in the composition of TGY mainly include gastrodin, gastrodia elata blume polysaccharides, p-hydroxybenzyl alcohol, rhynchophylline, baicalein, leonurine, stachydrine, geniposide, 2,3,5,4,-tetrahydroxystilbene-2-Ο-β-D-glucoside, pinoresinol diglucoside, pachymic acid, β-ecdysteroid, avicularin, etc. It has been found that TGY and these constituents have the effects of ferroptosis inhibition, anti-apoptosis, anti-inflammation, and oxidation resistance, and they can regulate neurotransmitters and autophagy, reduce cerebral edema reduction, lower blood lipid and blood pressure, and improve blood circulation through multiple targets and pathways. This paper reviewed the clinical application of and the mechanism of the whole prescription and single flavor drugs of TGY in the treatment of neurological diseases, so as to provide a theoretical basis for the clinical application of TGY and offer ideas for the follow-up mechanism research of this prescription.

Objective:To investigate the safety and efficacy of stent-assisted coil embolization in acute intracranial ruptured wide-necked aneurysms, and explore the safety of different antiplatelet drug regimens during perioperative period and the risk factors for prognoses.Methods:A perspective multicenter study was performed. A total of 417 patients with intracranial ruptured wide-necked aneurysms treated by stent-assisted coil embolization in Neurosurgery Departments of 4 hospitals (First Affiliated Hospital of Wenzhou Medical University [ n=41], Zhujiang Hospital of Southern Medical University [ n=111], Tangdu Hospital of Air Force Military Medical University [ n=100], and Xuanwu Hospital of Capital Medical University [ n=165]) from June 2017 to January 2020 were included. According to the different antiplatelet drugs regimens used in perioperative period, these patients were divided into loaded clopidogrel group ( n=87), loaded clopidogrel combined with aspirin group ( n=212), and tirofiban group ( n=118). Clinical data and perioperative complications of 3 groups were compared. Modified Rankin scale (mRS) was used to evaluate the prognoses of patients at discharge; differences of clinical data between the poor prognosis group and good prognosis group were compared. Independent risk factors for prognoses of patients with intracranial ruptured wide-necked aneurysms were analyzed by multivariate Logistic regression analysis. Receiver operating characteristic (ROC) curve was used to analyze the predictive values of risk factors in poor prognosis. Results:Degrees of aneurysm embolization immediately after surgery: Raymond grading I was noted in 351 patients (84.2%), grading II in 44 patients (10.6%), and grading III in 22 patients (5.2%). Perioperative complications were noted in 44 patients (10.6%), and death was noted in 4 (1%). Intraoperative thrombosis incidence of the loaded clopidogrel group, loaded clopidogrel combined with aspirin group and tirofiban group was 5.7% (5/87), 5.7% (12/212) and 0.8% (1/118); that in tirofiban group was significantly lower than that in the loaded clopidogrel group and loaded clopidogrel combined with aspirin group ( P<0.05). At discharge, 360 patients (86.3%) had good prognosis and 57 patients (13.7%) had poor prognosis. Multivariate Logistic regression analysis showed age≥60 years ( OR=3.407, 95% CI: 1.620-7.166, P=0.001), preoperative Hunt-Hess grading 3 ( OR=11.445, 95% CI: 3.584-36.547, P<0.001), preoperative Hunt-Hess grading 4 ( OR=88.951, 95% CI: 14.519-544.948, P<0.001), preoperative Hunt-Hess grading 5 ( OR=64.949, 95% CI: 12.809-329.325, P<0.001), and multiple stenting ( OR=4.709, 95% CI: 1.215-18.248, P=0.025) were independent risk factors for poor prognosis of these patients. ROC curves showed that area under the curve of combination of age, number of implanted stents, and preoperative Hunt-Hess grading in predicting poor prognosis of these patients was 0.821, with optimal diagnostic threshold of 0.500, sensitivity of 0.667, and specificity of 0.833. Conclusion:Stent-assisted coil embolization is safe and effective in acute intracranial ruptured wide-necked aneurysms; tirofiban is safe as perioperative antiplatelet drug; patients with old age, preoperative Hunt-Hess grading≥3, and multiple stents are prone to have poor prognosis.

Objective To investigate the application value of tenofovir alafenamide fumarate (TAF) in elderly patients with chronic hepatitis B (CHB) and its influence on bones and kidneys. Methods A total of 36 CHB patients, aged ≥60 years, who received TAF antiviral therapy in Qingdao Municipal Hospital, The Affiliated Hospital of Qingdao University, Qingdao Sixth People's Hospital, Chengyang People's Hospital, and Jimo People's Hospital from June 2021 to October 2022 were enrolled in this study, and all patients received TAF (25 mg/d) antiviral therapy. Related data were collected at baseline and weeks 24 and 48 of treatment, including virological indicators, biochemical parameters, urinary protein electrophoresis indices, transient elastography (FibroScan), and bone mineral density. Virological indicators included high-sensitivity HBV DNA quantification; biochemical parameters included total bilirubin, direct bilirubin (DBil), indirect bilirubin (IBil), alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase, total bile acid (TBA), glucose, blood urea nitrogen, creatinine, estimated glomerular filtration rate, and cystatin C (Cys C); urinary protein electrophoresis indices included urinary β2 microglobulin (β2-MG), urinary retinol (URBP), and urinary α1 microspherin (α1-MG). The paired t -test was used for comparison of normally distributed continuous data before and after treatment, and the Wilcoxon signed-rank test was used for comparison of non-normally distributed continuous data before and after treatment; the chi-square test or the Fisher's exact test was used for comparison of categorical data. Results A total of 36 CHB patients completed 24 weeks of follow-up. The complete virological response rate after 24 weeks of treatment was higher than that at baseline [83.3% (30/36) vs 77.8% (28/36), χ 2 =0.36, P =0.55], and there were significant reductions in DBil ( t =-2.42, P =0.02) and Cys C ( t =-4.34, P < 0.001) from baseline to week 24. A total of 18 CHB patients completed 48 weeks of follow-up. The complete virological response rate after 48 weeks of treatment was higher than that at baseline (94.4% vs 77.8%, χ 2 =2.22, P =0.34), and there were significant increases in IBil ( t =2.43, P =0.03), TBA ( Z =-2.24, P =0.03), and bone mineral density T score of lumbar vertebra ( t =2.92, P = 0.01) and femoral neck ( t =2.42, P =0.03) and a significant reduction in liver stiffness measurement ( t =-2.31, P =0.03). There were no significant changes in β2-MG, URBP, and α1-MG after treatment (all P > 0.05). Conclusion TAF has a good antiviral effect in CHB patients aged ≥60 years and can help more CHB patients achieve complete virological response, without causing damage to the kidney, and it can also improve bone mineral density and liver fibrosis degree.

Objective:To evaluate the role of P2X4 receptor (P2X4R) in the maintenance of trigeminal neuralgia and the relationship with p38 mitogen-activated protein kinase (p38 MAPK)/brain-derived neurotrophic factor (BDNF) signaling pathway in rats.Methods:Forty-eight clean-grade healthy adult male Sprague-Dawley rats, weighing 190-230 g, aged 2-3 months, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (S group), trigeminal neuralgia group (TN group), trigeminal neuralgia+ dimethylsulfoxide (DMSO) group (TN+ DMSO group), and trigeminal neuralgia+ P2X4R specific antagonist 5-BDBD group (TN+ 5-BDBD group). The model was developed by chronic constriction of the infraorbital nerve. The infraorbital nerve was only exposed without ligation in group S. At 3, 7, 10 and 14 days after developing the model, 5 μg/μl 5-BDBD 10 μl was intrathecally injected in TN+ 5-BDBD group, and 2% DMSO 10 μl was intrathecally injected in TN+ DMSO group. The facial mechanical pain withdrawal threshold (MWT) was measured at 1 day before developing the model and 1, 3, 7, 10, 14 and 28 days after developing the model (T 0-6). The rats were sacrificed and the trigeminal ganglia were taken for determination of the expression of P2X4R, p38 MAPK, phosphorylated p38 MAPK (p-p38 MAPK) and BDNF (by Western blot) and contents of tumor necrosis factor (TNF)-α and interleukin (IL)-1β and IL-6 (by enzyme-linked immunosorbent assay). Results:Compared with group S, the MWT was significantly decreased at T 1-6, the expression of P2X4R, p-p38 MAPK and BDNF in trigeminal ganglion was up-regulated, and the contents of TNF-α, IL-1β and IL-6 were increased in TN group ( P<0.05). Compared with TN group, the MWT was significantly increased at T 3-6, and the expression of P2X4R, p-p38 MAPK and BDNF in trigeminal ganglion was down-regulated, and the contents of TNF-α, IL-1β and IL-6 were decreased in TN+ 5-BDBD group ( P<0.05), and no significant change was found in the indexes mentioned above in TN+ DMSO group ( P>0.05). Conclusions:P2X4R is involved in the maintenance of trigeminal neuralgia in rats, which may be related to the activation of p38 MAPK/BDNF signaling pathway and the increase in inflammatory mediator release.

Objective:To analyze the non-enterovirus A71 (non-EVA71) and non-coxsackievirus A16 (non-CVA16) enteroviruses causing hand, foot and mouth disease (HFMD) in Kunming and Qujing of Yunnan Province in 2021 by sequencing the VP4/VP2 and VP1 genes and to analyze the phylogenetic characteristics of the VP1 gene of CVA2, aiming to provide reference for the prevention and control of CVA2.Methods:The samples were made and extracted strictly according to the Laboratory Manual for Hand, Foot and Mouth Disease (China Center for Disease Control and Prevention, 2018 Edition). VP4/VP2 junction regions were firstly amplified and sequenced by MD91/OL68-1 primers. These sequences were firstly edited and then "blasted" on the GenBank to determine the virus serotype. To analyze the phylogenetic characteristics of CVA2, the entire VP1 gene sequences were amplified in two segments using enterovirus species A primers. Virus serotype was again confirmed online by "Enterovirus Genotyping Tool Version 0.1". The sequences of the reference virus genotypes/sub-genotypes were downloaded according to the reference. The phylogenetic trees were constructed by Mega5.2 software and the genetic characteristics were analyzed.Results:A total of 749 non-EVA71 and non-CVA16 enteroviruses were detected in the two areas in 2021. Group A enteroviruses were the main pathogens, with CVA16 as the predominant virus, and a small number of group B enteroviruses were reported. Only five strains of CVA2 were detected with a detection rate of 0.67% (5/749), indicating that CVA2 was a rare pathogen for HFMD in the two areas. The sequencing and serotyping results were consistent using the two genomic regions of VP4/VP2 junction region and VP1 region. Phylogenetic analysis showed that three Kunming strains belonged to genotype A, while two Qujing strains belonged to genotype D.Conclusions:The detection rate of CVA2 in Kunming and Qujing was 0.67% in 2021. CVA2 was a rare pathogen for HFMD in the two regions. Phylogenetic analysis showed genotypes A and D spread in Kunming and Qujing, respectively, but had not caused epidemics. To our knowledge, this was the first report of genotype A of CVA2 in China. Strengthening the laboratory surveillance especially molecular epidemiological surveillance is valuable for the monitor and analysis of transmission source for CVA2.
