The weakening of γ-aminobutyric acid-mediated presynaptic inhibition may be an important cause of neuropathic pain. γ-aminobutyric acid-mediated presynaptic inhibition is related to the current strength of γ-aminobutyric acid A receptor activation. In view of this, the whole-cell patch-clamp technique was used here to record the change in muscimol activated current of dorsal root ganglion neurons in a chronic constriction injury model. Results found that damage in rat dorsal root ganglion neurons following application of muscimol caused concentration-dependent activation of current, and compared with the sham group, its current strength and γ-aminobutyric acid A receptor protein expression decreased. Immunofluorescence revealed that γ-aminobutyric acid type A receptor α2 subunit protein expression decreased and was most obvious at 12 and 15 days after modeling. Our experimental findings confirmed that the y-aminobutyric acid type A receptor α2 subunit in the chronic constriction injury model rat dorsal root ganglion was downregulated, which may be one of the reasons for the reduction of injury in dorsal root ganglion neurons following muscimol-activated currents.展开更多

OBJECTIVE: To o...BACKGROUND: Botulinum toxin type A (BTX-A) is mostly to be used to treat various diseases of motor disorders, whereas its effect on muscle spasm after stroke and brain injury needs further observation. OBJECTIVE: To observe the effect of BTX-A plus rehabilitative training on treating muscle spasm after stroke and brain injury. DESIGN: A randomized controlled observation. SETTINGS: Department of Rehabilitation, Department of Neurology and Department of Neurosurgery, the Second Hospital of Hebei Medical University. PARTICIPANTS: Sixty inpatients with brain injury and stroke were selected from the Department of Rehabilitation, Department of Neurology and Department of Neurosurgery, the Second Hospital of Hebei Medical University from January 2001 to August 2006. They were all confirmed by CT and MRI, and had obvious increase of spastic muscle strength in upper limbs, their Ashworth grades were grade 2 or above. The patients were randomly divided into treatment group (n =30) and control group (n =30). METHODS: ① Patients in the treatment group undertook comprehensive rehabilitative trainings, and they were administrated with domestic BTX-A, which was provided by Lanzhou Institute of Biological Products, Ministry of Health (S10970037), and the muscles of flexion spasm were selected for upper limbs, 20-25 IU for each site. ② Patients in the treatment group were assessed before injection and at 1 and 2 weeks, 1 and 3 months after injection respectively, and those in the control group were assessed at corresponding time points. The recovery of muscle spasm was assessed by modified Ashworth scale (MAS, grade 0-Ⅳ; Grade 0 for without increase of muscle strength; Grade Ⅳ for rigidity at passive flexion and extension); The recovery of motor function of the upper limbs was evaluated with Fugl-Meyer Assessment (FMA, total score was 226 points, including 100 for exercise, 14 for balance, 24 for sense, 44 for joint motion, 44 for pain and 66 for upper limb); The ADL were evaluated with Barthel index, the total score was 100 points, 60 for mild dysfunction, 60-41 for moderate dysfunction, < 40 for severe dysfunction). MAIN OUTCOME MEASURES: Changes of MAS grade, FMA scores and Barthel index before and after BTX-A injection. RESULTS: All the 60 patients with brain injury and stroke were involved in the analysis of results. ① FMA scores of upper limbs: The FMA score in the treatment group at 2 weeks after treatment was higher than that before treatment [(14.98±10.14), (13.10±9.28) points, P < 0.05], whereas there was no significant difference at corresponding time point in the control group. The FMA scores at 1 and 3 months in the treatment group [(23.36±10.69), (35.36±11.36) points] were higher than those in the control group [(20.55±10.22), (30.33±10.96) points, P < 0.01]. ② MAS grades of upper limbs: There were obviously fewer cases of grade Ⅲ in MAS at 2 weeks after treatment than before treatment in the treatment group (0, 9 cases, P < 0.05), whereas there was no obvious difference in the control group. There were obviously fewer cases of grade Ⅲ in MAS at 2 weeks and 1 month after treatment in the treatment group (0, 0 case) than the control group (5, 2 cases, P < 0.01). ③ Barthel index of upper limbs: The Barthel index at 2 weeks after treatment was higher than that before treatment in the treatment group [(30.36±22.25), (28.22±26.21) points, P < 0.05], whereas there was no significant difference in the control group. The Barthel indexes at 1 and 3 months after treatment in the treatment group were obviously higher than those in the control group [(20.55±10.22), (30.33±10.96) points, P < 0.01]. CONCLUSION: BTX-A has obvious efficacy on decreasing muscle tension after stroke and brain injury, and relieving muscle spasm; Meanwhile, the combination with rehabilitative training can effectively ameliorate the motor function of upper limbs and ADL of the patients.展开更多

文摘Hepatic encephalopathy is a serious neuropsychiatric complication caused by liver failure,which is characterized by the development of cognitive and motor disorders into coma.Typically,hepatic encephalopathy can be divided into three types(A,B,and C)according to the etiology.Type A hepatic encephalopathy(AHE)caused by acute liver failure seriously affects the prognosis of patients,ranging from mild neuropsychological changes to coma,brain edema,and even death.So far,the research on the pathogenesis of AHE has focused on the toxic effects of ammonia on the central nervous system,metabolic disorders(glutamine and lactate accumulation),neurotransmission alteration,systemic inflammation,especially neuro-inflammation.All these mechanisms are not independent,but mutually have synergistic effects.In clinic,treatment of AHE based on only one mechanism is often ineffective.To clarify the pathogenesis and the interaction among the mechanisms will be beneficial to the effective treatment of AHE and reduce the mortality.The aim of this review is to provide comprehensive scientific evidence for the clinical treatment of AHE via collecting and analyzing the latest mechanism of AHE,and clarifying the relationship among these mechanisms combing the investigation of the latest research progress of drug treatment of acute liver failure.Consequently,we find that the pathogenesis of AHE is a complex neurocognitive disorder shaped by interactions among hyperammonemia,inflammation,and changes in neurotransmission,the signaling pathways thereby integrating the inflammatory and neurological inputs to impact pathophysiological or neurobehavioral outcomes.

文摘Natural gas hydrate has huge reserves and is widely distributed in marine environment.Its commercial development is of great significance for alleviating the contradiction between energy supply and demand.As an efficient research method,numerical simulation can provide valuable insights for the design and optimization of hydrate development.However,most of the current production models simplify the reservoir as a two-dimensional(2D)horizontal layered model,often ignoring the impact of formation dip angle.To improve the accuracy of production prediction and provide theoretical support for the optimization of production well design,two three-dimensional(3D)geological models with different dip angles based on the geological data from two typical sites are constructed.The vertical well,horizontal well and multilateral wells are deployed in these reservoirs with different permeabilities to perform production trial,and the sensitivity analysis of dip angles is also carried out.The short-term production behaviors in high and low permeability reservoirs with different dip angles are exhibited.The simulation results show that 1)the gas and water production behaviors for different well types in the two typical reservoirs show obviously different variation laws when the short-term depressurization is conducted in the inclined formation;2)the inclined formation will reduce the gas production and increase the water extraction,and the phenomena becomes pronounced as the dip angle increases,particularly in the low-permeability reservoirs;3)and the impact of formation dip on hydrate recovery does not change significantly with the variation of well type.
文摘Purpose:Accurately assigning the document type of review articles in citation index databases like Web of Science(WoS)and Scopus is important.This study aims to investigate the document type assignation of review articles in Web of Science,Scopus and Publisher’s websites on a large scale.Design/methodology/approach:27,616 papers from 160 journals from 10 review journal series indexed in SCI are analyzed.The document types of these papers labeled on journals’websites,and assigned by WoS and Scopus are retrieved and compared to determine the assigning accuracy and identify the possible reasons for wrongly assigning.For the document type labeled on the website,we further differentiate them into explicit review and implicit review based on whether the website directly indicates it is a review or not.Findings:Overall,WoS and Scopus performed similarly,with an average precision of about 99% and recall of about 80%.However,there were some differences between WoS and Scopus across different journal series and within the same journal series.The assigning accuracy of WoS and Scopus for implicit reviews dropped significantly,especially for Scopus.Research limitations:The document types we used as the gold standard were based on the journal websites’labeling which were not manually validated one by one.We only studied the labeling performance for review articles published during 2017-2018 in review journals.Whether this conclusion can be extended to review articles published in non-review journals and most current situation is not very clear.Practical implications:This study provides a reference for the accuracy of document type assigning of review articles in WoS and Scopus,and the identified pattern for assigning implicit reviews may be helpful to better labeling on websites,WoS and Scopus.Originality/value:This study investigated the assigning accuracy of document type of reviews and identified the some patterns of wrong assignments.

文摘Objective Type A acute aortic dissection(TAAAD)is a dangerous and complicated condition with a high death rate before hospital treatment.Patients who are fortunate to receive prompt surgical treatment still face high in-hospital mortality.A series of post-operative complications further affects the prognosis.Post-operative pneumonia(POP)also leads to great morbidity and mortality.This study aimed to identify the prevalence as well as the risk factors for POP in TAAAD patients and offer references for clinical decisions to further improve the prognosis of patients who survived the surgical procedure.Methods The study enrolled 89 TAAAD patients who underwent surgical treatment in Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,Hubei province,China from December 2020 to July 2021 and analyzed the perioperative data and outcomes of these patients.Logistic regression analyses were used to identify the risk factors for POP.Results In the study,31.5%of patients developed POP.Patients with POP had higher proportions of severe oxygenation damage,pneumothorax,reintubation,tracheotomy,renal replacement therapy,arrhythmia,gastrointestinal bleeding,and longer duration of mechanical ventilation,fever,ICU stay,and length of stay(all with P<0.05).The in-hospital mortality was 2.3%.Smoking,preoperative white blood cells,and intraoperative transfusion were the independent risk factors for POP in TAAAD.Conclusion Patients who underwent TAAAD surgery suffered poorer outcomes when they developed POP.Furthermore,patients with risk factors should be treated with caution.
文摘Clinically,it is widely recognized that surgical treatment is the preferred and reliable option for Stanford type A aortic dissection.Stanford type A aortic dissection is an emergent and serious cardiovascular disease characterized with an acute onset,poor prognosis,and high mortality.However,the incidences of postoperative complications are relatively higher due to the complexity of the disease and its intricate procedure.It has been considered that hypoxemia,one of the most common postoperative complications,plays an important role in having a worse clinical prognosis.Therefore,the effective intervention of postoperative hypoxemia is significant for the improved prognosis of patients with Stanford type A aortic dissection.

文摘Introduction:Acute type A aortic dissection(ATAAD)is a catastrophic disease with fatal outcomes.Malperfusion syndrome(MPS)is a serious complication of ATAAD,with an incidence of 20–40%.Many studies have shown that MPS is the main risk factor for poor ATAAD prognosis.However,a risk scoring system for ATAAD based on MPS is lacking.Here,we designed a risk scoring system for ATAAD to assess mortality through quantitative assessment of relevant organ malperfusion and subsequently develop rational treatment strategies.Methods and analysis:This was a prospective observational study.Patients’perioperative clinical data were col-lected to establish a database of ATAAD(N≥3000)and determine whether these patients had malperfusion complica-tions.The Anzhen risk scoring system was established on the basis of organ malperfusion by using a random forest survival model and a logistics model.The better method was then chosen to establish a revised risk scoring system.Ethics and dissemination:This study received ethical approval from the Ethics Committees of Beijing Anzhen Hospital,Capital Medical University(KS2019034-1).Patient consent was waived because biological samples were not collected,and no patient rights were violated.Findings will be disseminated at scientific conferences and in peer-reviewed publications.
文摘Background:Botulinum toxin type A(BTX-A)is a neuromuscular blocking agent.BTX-A inhibits acetylcholine release,causes neuromuscular transmission impairment,and decreases muscle spasms.Objective:To explore the efficacy and safety of BTX-A injection in the treatment of spastic cerebral palsy through systematic evaluation and to provide a reference for the clinical use of BTX-A.Methods:We used“Cerebral palsy”and“BTX-A”as the subject terms and used a combination of subject terms and free words for the search.We searched 7 databases,including CNKI,Wanfang,VIP,Sinomed,PubMed,Embase,and Web of science.Based on the inclusion and exclusion criteria,we screened the articles by reading their titles,abstracts,and full texts and finally included relevant literature for systematic evaluation.Result:A total of 93 papers were systematically evaluated,revealing that BTX-A injection treatment can effectively reduce muscle tone,increase joint mobility,improve gait and motor posture,and enhance gross motor movements in patients with spastic cerebral palsy.The benefits of BTX-A treatment can be sustained for 3–6 months,with motor ability improvement lasting up to 1 year.Combining BTX-A treatment with rehabilitation or external fixation therapy can enhance its efficacy.However,the effectiveness of BTX-A treatment is influenced by several factors,such as the dosage,number of injections,and patient age.Adverse reactions to BTX-A treatment are typically mild and can be relieved within 1–2 weeks.Conclusion:BTX-A injection is relatively safe but reversible.
文摘The transmetallation reaction of 4 Schiff base type arylmercury compounds with metallic tin has been carried out in refluxing xylene.It was found that the reaction proceeds in the same manner as that of chloro[2-(phenylazo)phenyl]mercury(Ⅱ) to give dichlorobisaryltin(Ⅳ).The ~1H NMR spectra of the products provide evidence for the presence of N→Sn intramolecular coordination.The formation of dichlorobisaryltin(Ⅳ)as a unique product probably arises from the N→Sn intramolecular coordination which results in the increasing of the stability of the molecule.

文摘What is pursued by multi-product type and variant volume(MPTVV) production is rapid response and quick switching,so that structure of transferring line in manufacturing system is no longer unalterable.Cell formation(CF) algorithm is the key technology of cellular manufacturing system(CMS).Currently,CF methods are mainly extended on the idea of group technology(GT) that covers a lot on analysis of resource capability matching and its algorithm.Various constraints are considered,but seldom utilized comprehensively.Aimed to the problem of manufacturing cell(MC) formation under MPTVV production mode,integrated formation technologies for typical MC as group type of cell(GC),flow type of cell(FC) and inherited cell(IC) are presented based on technical analysis of CF.Oriented to practical production constraints like delivery time,product batch,equipment ability,key machine,key part and machine sharing,etc,an integrated formation model is constructed and internal interrelations of these constraints are analyzed synthetically.Ulteriorly,formation goals of types of MCs and their formation procedures under joint effect of formation constraints and rules are spread.In case study,three highly balanced GC are formed first;then FC formation are implemented based on the same data which indicate good balancing effect of cell load and flow-style production for key tasks;When task is adjusted,a new scheme is constructed on the result of FC configuration by using IC formation method,and more optimal performance of flow-style production is manifested.The proposed comparative study of different type of cells strongly explains the validation of integrated MC formation in support of rapid manufacturing resource transformation under MPTVV production mode.

文摘The γ-aminobutyric acid neurotransmitter in the spinal cord dorsal horn plays an important role in pain modulation through primary afferent-mediated presynaptic inhibition. The weakening of γ-aminobutyric acid-mediated presynaptic inhibition may be an important cause of neuropathic pain. γ-aminobutyric acid-mediated presynaptic inhibition is related to the current strength of γ-aminobutyric acid A receptor activation. In view of this, the whole-cell patch-clamp technique was used here to record the change in muscimol activated current of dorsal root ganglion neurons in a chronic constriction injury model. Results found that damage in rat dorsal root ganglion neurons following application of muscimol caused concentration-dependent activation of current, and compared with the sham group, its current strength and γ-aminobutyric acid A receptor protein expression decreased. Immunofluorescence revealed that γ-aminobutyric acid type A receptor α2 subunit protein expression decreased and was most obvious at 12 and 15 days after modeling. Our experimental findings confirmed that the y-aminobutyric acid type A receptor α2 subunit in the chronic constriction injury model rat dorsal root ganglion was downregulated, which may be one of the reasons for the reduction of injury in dorsal root ganglion neurons following muscimol-activated currents.

文摘Type A aortic dissection(AD)is one of the most serious cardiovascular diseases,whose risk predictors are controversial.The purpose of this research was to investigate how elongation accompanied by dilation of the ascending aorta(AAo)affects the relevant haemodynamic characteristics using image-based computational models.Five elongated AAos with different levels of dilation have been reconstructed based on the centerlines data of an elderly and an AD patient.Numerical simulations have been performed assuming an inflow waveform and a Windkessel model with three elements for all outflow boundaries.The numerical results have revealed that the elongation of AAo can disturb the systolic helical flow pattern between the root of AAo and the aortic arch.The helical flow inside the AAo starts to develop into a vortex flow when the elongated AAo becomes dilated.The vortex gives rise to a localized oscillatory shear index at the ostia of the brachiocephalic artery(BA)and the inner curve of the aortic arch.This study suggests that abnormal growth of AAo,especially accompanied by its moderate dilation,can be considered as morphological risk factors of AD.
文摘BACKGROUND Type A insulin resistance syndrome is a rare disorder caused by mutations in the gene encoding the insulin receptor.Its coexistence with ovarian serous papillary cystadenofibroma is even rarer.CASE SUMMARY A 14-year-old girl developed type A insulin resistance syndrome and showed high fasting insulin,glucose,and hemoglobin A1c(HbA1c)levels.The girl suffered from ovarian serous papillary cystadenofibroma.The laboratory results were as follows:fasting insulin was 2624.90 pmol/L and HbA1c was 8.5%.A heterozygous missense mutation on exon 20 of the insulin receptor gene(c.3601C>T,Arg1201Trp)was observed.The histopathological diagnosis was a cystic lesion that extended to the upper right uterus,indicating a right ovarian serous papillary cystadefibroma accompanied by focal interstitial hyperplasia.The patient was treated with metformin for over 6 mo.Additionally,laparoscopic resection(bilateral)of the ovarian lesion and laparoscopic intestinal adhesiolysis were performed under general anesthesia.Diet therapy combined with exercise was then initiated.The patient had an uneventful recovery.The patient also showed improved blood glucose control,with reduced levels of fasting insulin(857.84 pmol/L)and HbA1c(7.0%).CONCLUSION Insulin resistance may play a significant role in the induction of tumors.It is important to investigate further the association between insulin resistance and tumors and the underlying mechanism.

文摘BACKGROUND A 46-year-old male underwent ascending aortic replacement,total arch replacement,and descending aortic stent implantation for Stanford type A aortic dissection in 2016.However,an intraoperative stent-graft was deployed in the false lumen inadvertently.This caused severe iatrogenic thoracic and abdominal aortic dissection,and the dissection involved many visceral arteries.CASE SUMMARY The patient had pain in the chest and back for 1 mo.A computed tomography scan showed that the patient had secondary thoracic and abdominal aortic dissection.The ascending aortic replacement,total arch replacement,and descending aortic stent implantation for Stanford type A aortic dissection were performed 2 years prior.An intraoperative stent-graft was deployed in the false lumen.Endovascular aneurysm repair was performed to address this intractable situation.An occluder was used to occlude the proximal end of the true lumen,and a covered stent was used to direct blood flow back to the true lumen.A three-dimensional printing technique was used in this operation to guide prefenestration.The computed tomography scan at the 1stmo after surgery showed that the thoracic and abdominal aortic dissection was repaired,with all visceral arteries remaining patent.The patient did not develop renal failure or neurological complications after surgery.CONCLUSION The total endovascular repair for false lumen stent-graft implantation was feasible and minimally invasive.Our procedures provided a new solution for stent-graft deployed in the false lumen,and other departments may be inspired by this case when they need to rescue a disastrous stent implantation.

文摘BACKGROUND: Botulinum toxin type A (BTX-A) is mostly to be used to treat various diseases of motor disorders, whereas its effect on muscle spasm after stroke and brain injury needs further observation. OBJECTIVE: To observe the effect of BTX-A plus rehabilitative training on treating muscle spasm after stroke and brain injury. DESIGN: A randomized controlled observation. SETTINGS: Department of Rehabilitation, Department of Neurology and Department of Neurosurgery, the Second Hospital of Hebei Medical University. PARTICIPANTS: Sixty inpatients with brain injury and stroke were selected from the Department of Rehabilitation, Department of Neurology and Department of Neurosurgery, the Second Hospital of Hebei Medical University from January 2001 to August 2006. They were all confirmed by CT and MRI, and had obvious increase of spastic muscle strength in upper limbs, their Ashworth grades were grade 2 or above. The patients were randomly divided into treatment group (n =30) and control group (n =30). METHODS: ① Patients in the treatment group undertook comprehensive rehabilitative trainings, and they were administrated with domestic BTX-A, which was provided by Lanzhou Institute of Biological Products, Ministry of Health (S10970037), and the muscles of flexion spasm were selected for upper limbs, 20-25 IU for each site. ② Patients in the treatment group were assessed before injection and at 1 and 2 weeks, 1 and 3 months after injection respectively, and those in the control group were assessed at corresponding time points. The recovery of muscle spasm was assessed by modified Ashworth scale (MAS, grade 0-Ⅳ; Grade 0 for without increase of muscle strength; Grade Ⅳ for rigidity at passive flexion and extension); The recovery of motor function of the upper limbs was evaluated with Fugl-Meyer Assessment (FMA, total score was 226 points, including 100 for exercise, 14 for balance, 24 for sense, 44 for joint motion, 44 for pain and 66 for upper limb); The ADL were evaluated with Barthel index, the total score was 100 points, 60 for mild dysfunction, 60-41 for moderate dysfunction, < 40 for severe dysfunction). MAIN OUTCOME MEASURES: Changes of MAS grade, FMA scores and Barthel index before and after BTX-A injection. RESULTS: All the 60 patients with brain injury and stroke were involved in the analysis of results. ① FMA scores of upper limbs: The FMA score in the treatment group at 2 weeks after treatment was higher than that before treatment [(14.98±10.14), (13.10±9.28) points, P < 0.05], whereas there was no significant difference at corresponding time point in the control group. The FMA scores at 1 and 3 months in the treatment group [(23.36±10.69), (35.36±11.36) points] were higher than those in the control group [(20.55±10.22), (30.33±10.96) points, P < 0.01]. ② MAS grades of upper limbs: There were obviously fewer cases of grade Ⅲ in MAS at 2 weeks after treatment than before treatment in the treatment group (0, 9 cases, P < 0.05), whereas there was no obvious difference in the control group. There were obviously fewer cases of grade Ⅲ in MAS at 2 weeks and 1 month after treatment in the treatment group (0, 0 case) than the control group (5, 2 cases, P < 0.01). ③ Barthel index of upper limbs: The Barthel index at 2 weeks after treatment was higher than that before treatment in the treatment group [(30.36±22.25), (28.22±26.21) points, P < 0.05], whereas there was no significant difference in the control group. The Barthel indexes at 1 and 3 months after treatment in the treatment group were obviously higher than those in the control group [(20.55±10.22), (30.33±10.96) points, P < 0.01]. CONCLUSION: BTX-A has obvious efficacy on decreasing muscle tension after stroke and brain injury, and relieving muscle spasm; Meanwhile, the combination with rehabilitative training can effectively ameliorate the motor function of upper limbs and ADL of the patients.
文摘Accelerated rehabilitation surgery (ERAS) can promote postoperative recovery and reduce postoperative complications by minimizing surgically related stress, and its efficacy and safety in acute aortic dissection surgery have been demonstrated. However, due to the particularity of acute aortic dissection, studies on the application of accelerated rehabilitation surgery in acute aortic dissection are relatively rare and there are great differences among different studies. This study adopts the method of evidence-based nursing practice accelerate rehabilitation cluster of surgical nursing strategy developed and applied to the patients with primary acute aortic dissection and adopts “accelerate rehabilitation cluster of surgical nursing strategy” and “accelerated rehabilitation cluster of surgical nursing strategies in patients with acute aortic dissection in clinical intervention”, the new nursing concept and organic combination of traditional nursing measures, using the optimal cluster nursing intervention mode, to explore the safety, effectiveness and feasibility of the intervention mode in the perioperative period of the original acute aortic dissection in patients’ cluster intervention, to accelerate the rehabilitation surgery in acute aortic dissection in the clinical care to provide a scientific basis for the operation.
