ABSTRACT

Objective:To investigate the correlation between collateral flow compensation mode and interventional treatment decision in patients with severe bilateral internal carotid artery stenosis/occlusion.Methods:According to the location of internal carotid artery lesions, patients with severe stenosis/occlusion of bilateral internal carotid artery were selected at the Second Affiliated Hospital, Qiqihar Medical University and the Sixth Medical Center of PLA General Hospital from May 2017 to June 2020.Results:A total of 42 patients were finally enrolled and divided into 4 types, including 34 males and 8 females with median age 61±8(48-82)years. The collateral circulation pathways manifested as following modes: anterior communicating artery collateral, posterior communicating artery collateral, ophthalmic artery collateral, posterior cerebral middle cerebral artery pial anastomosis collateral, posterior choroidal artery anterior choroidal artery collateral, external carotid internal carotid artery C4 segment collateral, pericallosal artery anastomosis collateral, dural and pial collateral and neovascularization. Type Ⅰ severe stenosis/occlusion of C1 segment was found in 20 cases (47.6%). There were 5 cases (11.9%) of type Ⅱ severe stenosis/occlusion from C2 to C6 prior to ophthalmic artery branch. Type Ⅲ severe stenosis/occlusion occurred in 2 cases (4.8%) after the split of ophthalmic artery. Type Ⅳ was mixed type in 15 cases (35.7%).Conclusions:The compensatory pathway of collateral circulation is closely related to the lesion location. To explore the compensatory pattern of collateral circulation is helpful for clinicians to accurately analyze the lesion characteristics and guide individualized interventional therapy.

ABSTRACT

Objective:To investigate the collateral circulation compensation model in patients with favorable prognosis of basilar artery occlusion/severe stenosis treated with drugs or endovascular therapy.Methods:Clinical data of patients with basilar artery occlusion/severe stenosis and good clinical outcome were retrospectively collected in the Department of Neurology, Sixth Medical Center of PLA General Hospital from January 2019 to January 2020. They were divided into intensive drug therapy group and combined endovascular therapy group. The number and ways of collateral compensation pathway described by digital substraction angiography (DSA) were analyzed, and the characteristics of the collateral compensation model were summarized. SPSS22.0 software was used for statistical analysis, and the constituent ratio (%) was used for statistical description of the enumeration data.Results:A total of 32 eligible patients were included, including 27 males and 5 females, with an average age 45-76 (59±10) years. The compensation model included posterior communicating artery-posterior cerebral artery (13 cases, 40.6%), posterior communicating artery-posterior cerebral artery-basilar artery (10 cases, 31.2%), cerebellar artery-anastomotic branches of superior cerebellar artery (8 cases, 25.0%), anterior choroid artery-anastomotic branches of posterior choroid artery (2 cases, 6.2%), collateral circulation not established (11 cases, 34.4%).In drug treatment group, collateral compensation was found in the majority (14/15), with mainly posterior communicating artery (10/14).Most patients in combined treatment group did not develop collateral compensation (10/17), anastomotic branches of PICA-SCA were the main routes (6/7).Conclusion:In patients with basilar artery occlusion/severe stenosis, favorable clinical outcome can be achieved in both groups of patients treated with intensive drug therapy or endovascular therapy.

ABSTRACT

Objective:To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) for hemorrhagic transformation (HT) in patients with acute ischemic stroke (AIS).Methods:Consecutive patients with AIS without performing intravenous thrombolysis and mechanical thrombectomy admitted to the Cerebrovascular Disease Treatment Center, the Affiliated Brain Hospital of Nanjing Medical University from December 2015 to December 2020 were enrolled. The clinical, imaging and laboratory examination data were collected. HT was defined as the first imaging examination of AIS patients without finding bleeding signs, but the imaging reexamination after hospitalization found intracranial hemorrhage. Multivariate logistic regression analysis was used to determine the independent correlation between NLR and HT. The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for HT. Results:A total of 805 patients with AIS were included. The median age was 67 years (interquartile range, 63-71 years), the median National Institutes of Health Stroke Scale (NIHSS) score was 4 (interquartile range, 2-9), the median NLR was 3.84 (interquartile range, 2.66-5.30). Seventy-ywo patients (8.9%) had HT. There were significant differences in age, baseline systolic blood pressure, baseline NIHSS score, time from onset to admission, time from onset to blood collection, time from onset to imaging reexamination, NLR, atrial fibrillation, history of previous stroke and transient ischemic attack and stroke etiology between the HT group and the non-HT group (all P<0.05). Multivariate logistic regression analysis showed that NLR was an independent risk factor for HT in patients with AIS after adjusting for confounding factors (odds ratio 1.355, 95% confidence interval 1.099-1.672; P=0.005). The ROC curve analysis showed that the area under the curve of NLR predicting HT was 0.852, and the optimal cut-off value was 4.75. Its sensitivity and specificity of predicting HT were 88.3% and 71.8% respectively. Conclusion:High NLR is an independent risk factor for HT in patients with AIS during hospitalization, and had better predictive value for HT risk.

ABSTRACT

Sojae Semen Germinatum was firstly recorded in Shennong Bencaojing, and it has a long history of edible and medicinal use. Most ancient medical practitioners described that Sojae Semen Germinatum was processed with black soya bean, while some others recorded that Sojae Semen Germinatum was processed with black soya bean and soybean or with soybean only. In modern times, black soya bean and soybean are both used. Before the Northern and Southern dynasties, the germination process of Sojae Semen Germinatum was mostly soil culture, and then changed into water culture later. The medicinal part of Sojae Semen Germinatum may also change from the initial aboveground part to the whole processed products including the soybean and the bud. The bud length was used to control the processing ending of Sojae Semen Germinatum, but there were different views of the bud length in ancient and modern times. Before the Tang dynasty, Sojae Semen Germinatum was mostly used directly. Since the Tang dynasty, various subsequent processed products of Sojae Semen Germinatum appeared. Most ancient medical practitioners confirmed that Sojae Semen Germinatum was sweet flavor, neutral in nature and non-toxic, and the mainstream believed that it belonged to the spleen, lung and stomach meridians. However, there were different opinions on its efficacy of relieving exterior syndrome by diaphoresis. In this paper, the evolution of Sojae Semen Germinatum was explored after consulting all kinds of ancient books, its historical name, processing history, quality evaluation and others were systematically summarized in order to clarify its historical development and lay a good foundation for the clinical use and further development of Sojae Semen Germinatum.

ABSTRACT

One-sixth of the currently known natural products contain α, β-unsaturated carbonyl groups. Our previous studies reported a rare C-sulfonate metabolic pathway. Sulfonate groups were linked to the β-carbon of α, β-unsaturated carbonyl-based natural compounds through this pathway. However, the mechanism of this type of metabolism is still not fully understood, especially whether it is formed through enzyme-mediated biotransformation or direct sulfite addition. In this work, the enzyme-mediated and non-enzymatic pathways were studied. First, the sulfite content in rat intestine was determined by LC-MS/MS. The results showed that the amount of sulfite in rat intestinal contents was from 41.5 to 383 μg·g

ABSTRACT

OBJECTIVE@#To explore the clinical efficacy and safety of posterior intervertebral foraminal discectomy via Delta channel for cervical spondylotic radiculopathy in the early phase.@*METHODS@#From September 2017 to July 2018, 10 patients with cervical spondylotic radiculopathy underwent posterior intervertebral foraminal discectomy via Delta channel. There were 6 males and 4 females, aged from 30 to 62 years old with an average of (41.5±4.3) years old. All of them had unilateral symptoms caused by cervical nerve root compression, including 2 cases of C, 5 cases of C and 3 cases of C. CT and MRI examination of all the patients did not show ossification of posterior longitudinal ligament or calcification of ligamentum flavum, and no cervical spine instability was present in dynamic radiographs. The clinical outcome was poor after more than 6 weeks of systematic non-surgical treatment. The VAS score, JOA score, NDI score, the cervical spine physiological curvature, and the height and stability of the compressed cervical vertebrae were measured before operation and at the latest follow-up.@*RESULTS@#All patients successfully completed the surgeries without any spinal cord, nerve root or major blood vessel injury. The operation time was 70 to 120 min with an average of 90 min. Intraoperative blood loss ranged from 30 to 90 ml with an average of 40 ml. All the 10 patients were followed up for 6 to 14 months with an average of 9 months. Postoperative nerve root pain got relievd and nerve function was improved in all patients. VAS score decreased from 7.15±2.01 before surgery to 1.59±0.83 at the latest follow-up;JOA score increased from 12.57±1.24 before surgery to 16.42±0.58 at the latest follow-up;NDI score increased from 41.82±4.71 before surgery to 9.59±3.52 at the latest follow-up. All the results above presented significant difference between latest follow-up and preoperative (0.05). At the latest follow-up, no cervical instability was observed on dynamic radiographs.@*CONCLUSION@#Treatment of cervical spondylotic radiculopathy by posterior intervertebral foraminal discectomy via Delta channel can obtain a satisfactory clinical outcome without affecting the stability of cervical vertebra.

ABSTRACT

Recently a COVID-19 pneumonia pandemic caused by a novel coronavirus 2019-nCoV has broken out over the world. In order to better control the spread of the pandemic, there's an urgent need to extensively study the virus' origin and the mechanisms for its infectivity and pathogenicity. Spike protein is a special structural protein on the surface of coronavirus. It contains important information about the evolution of the virus and plays critical roles in the processes of cellular recognition and entry. In the past decades, spike protein has always been one of the most important objects in research works on coronaviruses closely related to human life. In this review we introduce these research works related to spike proteins, hoping it will provide reasonable ideas for the control of the current pandemic, as well as for the diagnosis and treatment of COVID-19.

ABSTRACT

Sojae Semen Germinatum (SSG) was firstly recorded in Shennong Bencaojing. It is a dry processed product which is germinated using mature seeds of Glycine max. It is neutral in nature and sweet flavor, and its functions are to relieve heat, clear away heat and remove dampness. SSG has a long history of being used both as food and medicine, but it was not enrolled in the Chinese Pharmacopoeia until 2010. Doctors of different dynasties had different views of its processing procedures, and thus the quality of its decoction pieces is inconsistent. This article systematically straightened out the records of SSG in ancient books and modern literature, and summarized and analyzed the processing procedures, chemical constituents, quality analysis and pharmacological effects of SSG. It found that SSG contains proteins, isoflavones, saponins and other components, analytical methods for detecting these components include ultraviolet spectrophotometry (UV), thin-layer chromatography (TLC), high performance liquid chromatography (HPLC), etc. It has effect such as antioxidant, anti-inflammatory, anti-osteoporosis, improvement of menopausal syndrome, treatment of cardiovascular diseases, and processing will change the type and content of its chemical components. Therefore, it is necessary to dig out active constituents of SSG, explore those changes in chemical constituents and pharmacological effect during the period of its primary and subsequent processing, and explore its action mechanism. This paper can provide the theoretical basis for standardized processing procedure, modern quality control and clinical application of SSG.

ABSTRACT

Objective:To explorer the optimal method of detecting donor kidney carrier carbapenem-resistant Klebsiella pneumoniae (CRKP).Methods:Clinical data were retrospectively analyzed for 1120 donation-after-circulatory-death (DCD) kidneys and bacterial detection of kidney perfusion fluid was performed from January 2015 to January 2019. A total of 1120 kidney perfusion fluid samples were collected with sterile tubes and submitted for culturing. And 451 specimens were delivered in sterile tubes and blood culture bottles simultaneously And 729 specimens assayed for carbapenemase genes with GeneXpert.Results:Among 1120 kidneys, CRKP was confirmed in 21 grafts with an infection rate of 1.87 %. The detection of carbapenemase genes with Genexpert showed that KPC was positive for 9/16 CRKP positive grafts. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 56.3 %, 100 %, 0, 43.7 % and 0.781 respectively. And 11 specimens delivered with sterile tube were culture positive for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 52.3 %, 100 %, 0, 47.6 % and 0.762 respectively. Among 451 perfusion fluid samples collected with anaerobic blood culture bottle, 15 samples had a positive culture for CRKP. Sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 100 %, 100 %, 0, 0 and 1 respectively. In terms to anaerobic blood culture bottle, sensitivity, specificity, false-positive rate, false-negative rate and ROC-AUC were calculated at 60 %, 100 %, 0 , 40 % and 0.80 respectively.Conclusions:Genexpert assay is suitable for rapid and convenient detection of carbapenemase genes using kidney perfusion fluid. Culturing perfusion fluid samples collected with anaerobic blood culture bottle is clinically valuable diagnostic tool of CRKP.

ABSTRACT

Objective:To compare the curative effect of hematoma removal and minimally invasive puncture drainage in hypertensive intracerebral hemorrhage (HICH) under neuroendoscope.Methods:The clinical data of 118 patients with HICH admitted to our hospital from February 2017 to November 2019 were retrospectively analyzed. According to the different surgical methods, the patients were divided into group A ( n=59, minimally invasive puncture and drainage) and group B ( n=59, neuroendoscopic hematoma removal). The perioperative indexes, complications and neurological function indexes [neuron specific enolase (NSE), neurotrophic factor (NGF), substance P (SP)], inflammatory factor index [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] and related scale scores [National Institutes of Health Stroke Scale (NIHSS), modified Barthel Index (mBI)] were compared between the two groups. Results:The operation time, cerebrospinal fluid recovery time, hematoma removal time and hospitalization time of group B were shorter than those of group A ( P<0.05). On the 7th day after operation, the NSE, SP, IL-6, TNF-α in the two groups were decreased, and the levels of NSE, SP, IL-6 and TNF-α in group B were lower than those in group A ( P<0.05); on the 7th day after operation, the levels of NGF in two groups were increased, and those in group B were higher than those in group A ( P<0.05). 6 months after operation, the NIHSS decreased and mBI increased in both groups ( P<0.05), and NIHSS in group B was lower than that in group A, but mBI was higher than that in group A ( P<0.05). There was no difference in the incidence of complications between the two groups ( P>0.05). Conclusions:Compared with minimally invasive puncture and drainage, neuroendoscope hematoma removal for HICH patients can effectively improve perioperative indicators, reduce neurological damage and body inflammatory stimulation, and improve the self-care ability of patients, which is safe and reliable.

ABSTRACT

Objective:To investigate the effect of exosomes (Exo) secreted by brain vascular endothelial cell bEnd.3 after ischemic preconditioning (IPC) on neurons suffering from oxygen and glucose deprivation (OGD).Methods:bEnd.3 was exposed to OGD for 3 h to simulate IPC in vivo. After 48 h of reoxygenation, the Exo (IPC Exo) in the conditioned medium were extracted and identified by Western blot and transmission electron microscopy. IPC Exo were incubated with primary cultured mouse cortical neurons for 24 h. Confocal microscope was used to observe whether Exo could be uptaked by primary cultured mouse cerebral cortical neurons. The primary cultured cortical neurons were divided into control group, OGD group, OGD+ IPC Exo (5 μg/ml, 10 μg/ml, 20 μg/ml) groups and sham OGD group (treated with Exo secreted by bEnd.3 cultured under normoxia conditions). The cell viability was detected by CCK-8 and cell survival/death detection kit.Results:Transmission electron microscopy showed that the extract of bend.3 culture medium showed typical morphology of Exo, i. e., a double concave disc-shaped vesicle with a diameter of 30-100 nm. Western blot analysis showed that the extract of bEnd.3 medium highly expressed Exo markers Alix and Tsg101. Confocal microscopy showed that Exo could be uptaked by primary cultured mouse cortical neurons, and the uptake of Exo was widely distributed in the cytoplasm and synapses. Compared with the OGD group, the addition of 10 and 20 μg/ml IPC Exo could significantly increased the neuronal viability ( P<0.05), while the addition of sham Exo had no neuroprotective effect. Conclusion:Exo released by cerebral vascular endothelial cells after IPC have protective effect on neurons suffering from OGD.

ABSTRACT

Objective:To investigate the risk factors for bleeding at femoral artery puncture site after neurointervention and to compare the effectiveness of different hemostatic methods.Methods:Patients underwent whole brain angiography and cerebrovascular interventional therapy in the Department of Neurology, the Fourth Affiliated Hospital of Nanjing Medical University from November 2017 to May 2019 were collected retrospectively. According to the situation of femoral artery puncture site after sheath removal, the patients were divided into bleeding group and non-bleeding group. The baseline data, laboratory tests, and intraoperative data were compared between the two groups. Multivariate logistic regression analysis was used to determine the independent risk factors for bleeding at femoral artery puncture site. The hemostasis time of different diameter vascular sheath (5 F, 6 F or 8 F) under different hemostasis schemes (manual compression, vascular stapler, and vascular occluder) were analyzed. Results:A total of 721 patients performed neurointervention were included, including 264 interventional therapy and 457 whole brain angiography. Forty-six patients (6.4%) had bleeding at the puncture site after procedure, including 25 patients (3.5%) with oozing of blood, 18 (2.5%) with hematoma, and 3 (0.4%) with pseudoaneurysm. Multivariate logistic regression analysis showed that intraoperative systolic blood pressure (odds ratio [ OR] 1.025, 95% confidence interval [ CI] 1.004-1.047; P=0.021), number of punctures ( OR 1.075, 95% CI 1.053-1.097; P<0.001), heparin dose ( OR 2.142, 95% CI 1.638-3.471; P<0.001), operation time ( OR 3.727, 95% CI 2.025-6.860; P<0.001) and manual compression ( OR 3.449, 95% CI 1.230-9.669; P=0.019) were the independent risk factors for bleeding at the puncture site after operation. No matter which hemostasis scheme was used, the hemostasis time would be prolonged with the increase of the diameter of the vascular sheath, but there was a significant statistical difference in hemostasis time of different vascular sheath diameter groups only when using manual compression ( P<0.05). In addition, no matter what the diameter of vascular sheath was, the hemostasis time of using vascular stapler and vascular occluder was significantly shorter than that of manual compression, and there was statistical significance between the groups ( P<0.05). Conclusion:Reducing the number of punctures, shortening the operation time, and using different hemostatic methods for different diameter vascular sheaths can reduce the incidence of bleeding at the femoral artery puncture site.

METHODS:Retrieved from PubMed ,Cochrane library ,Embase,CNKI,CBM,Wanfang database and VIP during inception to June of 2019,randomized controlled trials about DEX (trial group )versus normal saline (control group )in the prevention of adverse drug reactions induced by carboprost tromethamine in cesarean section were collected. After data extraction of included literatures and quality evaluation with modified Jadad scale ,Meta-analysis was performed by using Rev Man 5.3 statistical software. RESULTS :A total of 11 RCTs with 714 patients were included in this study. Results of Meta-analysis showed that the incidence of nausea [OR =0.09,95%CI(0.06,0.14),P<0.000 01],vomiting [OR =0.09,95%CI(0.05,0.15),P<0.000 01], facial flushing [OR =0.15,95%CI(0.10,0.22),P<0.000 01],chest distress [OR =0.12,95%CI(0.08,0.18),P<0.000 01], hypertension [OR =0.06,95%CI(0.04,0.11),P<0.000 01] and tachycardia [OR =0.17,95%CI(0.12,0.25),P<0.000 01] in trial group were significantly lower than control group ,with statistical significance. CONCLUSIONS :DEX can reduce adverse drug reactions such as nausea and vomiting caused by carboprost tromethamine used in cesarean section.

ABSTRACT

OBJECTIVE:To study the potential ris k of Chinese patent medicine for the treatment of stable chronic obstructive pulmonary disease (COPD),and to provide reference for the safety of clinical drug use. METHODS :Retrieved from Chinese journal full-text database ,CBM,Wanfang database and VIP ,using“stable”“Chronic obstructive pulmonary disease ”“COPD” “Chinese patent medicine ”as retrieval words ,relative literatures about Chinese patent medicine in the treatment of stable COPD were retrieved ,and retrieval time limitation was from their establishment to Sept. 2019. The type and components of Chinese patent medicine were collected. The potential risk of Chinese patent medicine was analyzed in terms of the contraindications of traditional Chinese medicines ,the interaction between traditional Chinese medicines and chemical medicines ,and its effects on stable COPD with other common chronic diseases. RESULTS :Eleven related studies covering 29 kinds of Chinese patent medicines for the treatment of stable COPD were included in this study. There were several incompatibility between two Chinese patent medicines containing Aconitum carmichaelii and eleven Chinese patent medicines containing “Pinellia ternata ,Trichosanthes kirilowii , Bolbostemma paniculatum ,Ampelopsis japonica ,Bletilla striata ”as an ancient rule of traditional Chinese medicine incompatibility “Eighteen antagonisms ”and“Nineteen mutual ”inhibitors. Meanwhile ,it should be avoided that four Chinese patent medicines containing ephedra combined with β2 receptor agonists or theophylline. Moreover ,oral antibiotics and 14 kinds of Chinese patent medicine containing licorice would reduce the curative effect. In addition ,patients with stable COPD who also had hypertension , hyperlipidemia or diabetes should be careful to use Chinese patent medicines containing ingredients such as Glycyrrhiza uralensis , A. carmichaelii ,Ephedra sinica ,Citrus aurantium ,Cornus officinalis ,Fritillaria cirrhosa ,Panax ginseng (Panax notoginseng ). CONCLUSIONS:There are many potential risks (such as combined use ,compatibility)in the use of Chinese patent medicines for stable COPD. It is suggested to comprehensively evaluate the patient ’s previous medical history and medication before using Chinese patent medicines ,so as to provide scientific guide for clinical rational medication.

ABSTRACT

Objective To explore the rapid diagnosis and clinic treatment of donor-derived carbapenem-resistant Klebsiella pneumoniae (CRKP) infection in renal transplant recipients .Methods Retrospective analysis was performed for clinical data and the diagnosis and treatment of 9 renal transplant recipients with donor-derived CRKP infection from March 2017 to May 2019 .Results Among 526 renal transplant recipients ,nine were diagnosed with donor-derived CRKP infection by bacterial culture or KPC enzyme gene test .The infection rate was 1 .71% .One recipient receiving carbapenem and tigecycline died while the remainders survived after a treatment of ceftazidime-avibactam and carbapenem . One recipient underwent graft resection . Among 8 recipients on ceftazidime-avibactam ,5 cases received a standard dose of 3 .75 g/d while another 3 cases had a high dose of 7 .5 g/d .One patient in standard-dose group underwent graft resection due to an arteriorrhexis of artery anastomosis .After graft resection ,the patient received a high dose of ceftazidime-avibactam and survived to date .The grafts of three patients in high-dose treatment group survived .Conclusions KPC enzyme gene detection plus injecting lavage fluid into blood culture bottle for bacterial culture is rapid and accurate for diagnosing donor-derived CRKP infection . A combination of ceftazidime-avibactam plus carbapenem is effective for donor-derived CRKP infection .A high dose of ceftazidime-avibactam may improve the efficacy without obvious side effects .
