ABSTRACT

Objective To explore the antitussive action site and potential mechanism of Shegan Zhike Capsule.Methods The mouse cough model induced by concentrated ammonia was used to observe the dose effect relationship of the antitussive effect of Shegan Zhike capsule.The central antitussive effect of Shegan Zhike capsule was observed by using the cough model induced by electrical stimulation of superior laryngeal nerve in guinea pigs.The peripheral antitussive effect of Shegan Zhike capsule was observed by using the cough model of capsaicin desensitized guinea pigs induced by mechanical stimulation.The model of chronic bronchitis in guinea pigs was established by smoking,and the effects of Shegan Zhike Capsule on vasoactive amines histamine(HA)and 5-hydroxytryptamine(5-HT)were observed.Results Shegan Zhike capsule could significantly reduce the number of coughs in mice at the doses of 43.00,86.00 and 172.00 mg extract·kg-1(P<0.05 or P<0.01).The low-dose group,the middle-dose group,and the high-dose group of Shegan Zhike Capsule did not significantly inhibit the cough inducing effect of electrical stimulation of guinea pig superior laryngeal nerve at 30 min and 60 min after administration.Shegan Zhike capsule could significantly inhibit the cough of capsaicin desensitized guinea pigs caused by mechanical stimulation in the low dose group at 60 min,the medium dose group at 30 min and the high dose group at 30 min and 60 min(P<0.05).Compared with the model control group,the content of HA in serum of guinea pigs in low,medium and high dose groups of Shegan Zhike capsule decreased significantly(P<0.05 or P<0.01).The content of serum 5-HT in the high dose group decreased significantly(P<0.05).Conclusion The antitussive effect of Shegan Zhike Capsule was not in the center,and its peripheral antitussive effect was related to the inhibition of RARs receptors,and vasoactive amines such as HA and 5-HT were also involved.

ABSTRACT

Objective:To analyze the clinical characteristics of benign paroxysmal positional vertigo (BPPV) in the oldest old.Method:The clinical data of elderly patients (≥60 years old) with BPPV diagnosed in the Clinical Center for Vertigo and Balance Disturbance of Capital Medical University between January 2019 and October 2021 was collected, including basic information, clinical symptoms in a structured medical history questionnaire and the time interval from the appearance of symptoms to medical consultation. According to the age, patients were divided into elderly group (60-74 years old) and the oldest old group (≥75 years old), and the demographic information, clinical symptoms and consultation time were compared between the two groups.Results:A total of 3 019 patients with BPPV were included in analysis; there were 415 patients in the oldest-old group with the age of (79.54±3.62) years, and 2 604 patients in the elderly group with the age of (65.59±3.88) years. The incidence of vertigo, dizziness or vertigo triggered by position changes of head or body, headache and autonomic symptoms in the eldest-old group were less common than that in the elderly group (all P<0.05). But hearing loss and other types of dizziness (unable to determine the nature of dizziness or vertigo, or without typical symptoms such as dizziness, balance disorders, or instability) were more common in the eldest-old group than those in the elderly group (all P<0.05). Among 3 019 patients, 1 137 had definite time from symptom onset to diagnosis (1 004 in the elderly group and 133 in the oldest-old group), the proportion of patients with the time from the onset to diagnosis>7 days in the oldest-old group was higher than that in the elderly group ( P<0.05). Conclusion:The oldest old patients with BPPV have more atypical symptoms than the younger elderly patients.

ABSTRACT

Objective@#To screen dynamic cardiorespiratory fitness indices for effective assessment of aerobic endurance using incremental load exercise tests.@*Methods@#From March to November 2019, 266 volunteers who were able to understand the trial and voluntarily cooperated with the entire testing process were randomly recruited from 5 universities in Beijing. Gas metabolism and cardiac function were monitored in real time using the German Cortex Metalyzer 3B system and the US Cheetah NICOM system, and maximum oxygen uptake was measured by a linear incremental loading scheme. Aerobic endurance and dynamic cardiopulmonary function indices were selected according to the study design, and the relationship between the two indicators was analyzed using correlation and typicality correlation.@*Results@#The absolute maximum oxygen uptake (VO 2max ), relative maximum oxygen uptake, maximum stroke volume (SV max ), and maximum stroke volume index (SVI max ) were significantly higher in males than in females, and the dynamic cardiopulmonary function index K was significantly lower than in females ( t =17.8, 10.1, 8.5, 4.3 , -6.3, P < 0.05 ). Simple correlation revealed that absolute VO 2max and relative VO 2max were negatively correlated with K and b, and absolute VO 2max and relative VO 2max were positively correlated with SV max and SVI max ( P <0.01); Both dynamic cardiopulmonary function indices were significantly correlated with aerobic endurance. Aerobic endurance indexes closely related to dynamic cardiopulmonary function were absolute VO 2max , relative VO 2max ; dynamic cardiopulmonary function indexes closely related to aerobic endurance were K, b, SV max , SVI max .@*Conclusion@#Improvement of dynamic cardiorespiratory fitness contributes to the improvement of aerobic endurance, the dynamic cardiorespiratory fitness indices K, b, SV max , and SVI max can be used as important candidates to predict the assessment of aerobic exercise capacity.

ABSTRACT

OBJECTIVE@#To compare the effectiveness between unilateral biportal endoscopic lumbar interbody fusion (ULIF) and endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) in treatment of lumbar spinal stenosis combined with intervertebral disc herniation.@*METHODS@#A clinical data of 64 patients with lumbar spinal stenosis and intervertebral disc herniation, who were admitted between April 2020 and November 2021 and met the selection criteria, was retrospectively analyzed. Among them, 30 patients were treated with ULIF (ULIF group) and 34 patients with Endo-TLIF (Endo-TLIF group). There was no significant difference in baseline data such as gender, age, disease duration, lesion segment, preoperative visual analogue scale (VAS) score of low back pain and leg pain, Oswestry disability index (ODI), spinal canal area, and intervertebral space height between the two groups ( P>0.05). The operation time, intraoperative blood loss, hospital stays, and postoperative complications were compared between the two groups, as well as the VAS scores of low back pain and leg pain, ODI, and imaging measurement indicators (spinal canal area, intervertebral bone graft area, intervertebral space height, and degree of intervertebral fusion according to modified Brantigan score).@*RESULTS@#Compared with the Endo-TLIF group, the ULIF group had shorter operation time, but had more intraoperative blood loss and longer hospital stays, with significant differences ( P<0.05). The cerebrospinal fluid leakage occurred in 2 cases of Endo-TLIF group and 1 case of ULIF group, and no other complication occurred. There was no significant difference in the incidence of complications between the two groups ( P>0.05). All patients in the two groups were followed up 12 months. The VAS scores of lower back pain and leg pain and ODI in the two groups significantly improved when compared with those before operation ( P<0.05), and there was no significant difference between different time points after operation ( P>0.05). And there was no significant difference between the two groups at each time point after operation ( P>0.05). Imaging examination showed that there was no significant difference between the two groups in the change of spinal canal area, the change of intervertebral space height, and intervertebral fusion rate at 6 and 12 months ( P>0.05). The intervertebral bone graft area in the ULIF group was significantly larger than that in the Endo-TLIF group ( P<0.05).@*CONCLUSION@#For the patients with lumbar spinal stenosis combined with intervertebral disc herniation, ULIF not only achieves similar effectiveness as Endo-TLIF, but also has advantages such as higher decompression efficiency, flexible surgical instrument operation, more thorough intraoperative intervertebral space management, and shorter operation time.

ABSTRACT

On December 22,2021,the United States Food and Drug Administration approved the first main protease inhibitor,i.e.,oral antiviral nirmatrelvir(PF-07321332)/ritonavir(Paxlovid),for the treatment of early severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection.Nirmatrelvir inhibits SARS-CoV-2 infection,but high doses or long-term treatment may cause embryonic developmental toxicity and changes in host gene expression.The chiral structure of nirmatrelvir plays a key role in its antiviral activity.Ritonavir boosts the efficacy of nirmatrelvir by inactivating cytochrome P450 3A4 expression and occupying the plasma protein binding sites.Multidrug resistance protein 1 inhibitors may increase the efficacy of nirmatrelvir.However,Paxlovid has many contraindications.Some patients treated with Paxlovid experience a second round of coronavirus disease 2019(COVID-19)symptoms soon after re-covery.Interestingly,the antiviral activity of nirmatrelvir metabolites,such as compounds 12-18,is similar to or higher than that of nirmatrelvir.Herein,we review the advances and challenges in using nirmatrelvir and its derivatives with the aim of providing knowledge for drug developers and physicians in the fight against COVID-19.

ABSTRACT

Systemic juvenile idiopathic arthritis is one of the common rheumatic and immune diseases in children. It has a sudden onset, obvious systemic symptoms, and lung involvement. However, systemic juvenile idiopathic arthritis with an early manifestation of pulmonary ground-glass opacities combined with macrophage activation syndrome is rare. The clinical data of a child with systemic juvenile idiopathic arthritis with pulmonary ground-glass shadow and macrophage activation syndrome who was admitted to Hubei Maternal and Child Health Care Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology in December 2021 were analyzed retrospectively in order to improve the understanding of rheumatic diseases and pulmonary lesions. The child was admitted to the hospital for 10 days due to rash and fever. Thoracic CT showed scattered ground glass like shadows in both lungs due to the prevention and control screening of COVID-19 pneumonia epidemic situation. After admission, the child was still repeatedly flaccid with high fever, accompanied by dysfunction of both lower limbs. The knee joint MRI found that there was synovitis in the knee joint, and various laboratory indicators suggested macrophage activation syndrome. After that, systemic juvenile idiopathic arthritis was diagnosed. After being treated with methylprednisolone, cyclosporine and topzumab, the clinical remission and the ground-glass shadow of the lung basically disappeared. Through the analysis of this case, it is suggested that clinicians should not ignore other diseases that cause ground glass shadow in the lung during the current epidemic of COVID-19.

ABSTRACT

Objective:To evaluate the volume changes of cervical longus and cervical extensor after anterior cervical discectomy and fusion (ACDF), and the correlation with the clinical efficacy of patients.Methods:All of 57 patients with cervical spondylotic myelopathy who underwent single-segment ACDF surgery from January 2013 to December 2018 were analyzed. The follow-up time was 23.0±4.8 months (range 16-34 months). All included subjects underwent MR examination within 1 week before operation and 3rd, 12th months after operation and at the last follow-up. The axial section cross section area (AxCSA) of the cervical longus and the ratio of length to short diameter line (RLS) at the level of each disc of C 2-C 7 were measured on the axial T2WI. Calculate the volume of the cervical longus based on the layer thickness. At the same time, measure the cervical extensor cross-sectional area (CESA) of the same level including the multifidus, cervical semispinous muscle, semispinous head, splinter head, and cervical splinter muscles, and compare CESA with the corresponding vertebral cross-sectional area (VBA). The ratio is analyzed as the volume of the neck extensor muscle, namely CESA/VBA. At the 3rd and 12th months after operation and at the last follow-up, the axial pain was assessed by visual analogue scale (VAS) for assessing pain, and the modified Japanese Orthopedic Association score (mJOA) and the neck dysfunction index (NDI) were used to assess the functional status of the cervical spine. Analyze the morphological changes of thecervical longus and extensor cervical muscles before and after the operation and during the follow-up period, and analyze the correlation with VAS, mJOA, and NDI. Results:Compared with the preoperative period, the average AxCSA of the surgical segment decreased at the 3rd and 12th months after the operation and at the last follow-up. The difference was statistically significant ( F=24.113, P<0.05), which was changed from 140.84±19.51 mm 2 respectively reduce to 117.74±17.15 mm 2 ( t=6.714, P<0.05), 116.37±18.67 mm 2 ( t=6.841, P<0.05) and 116.27±18.65 mm 2 ( t=6.873, P<0.05). Compared with preoperatively, they were reduced by 16.40%, 17.37% and 17.45%, respectively, while the average RLS of surgical segments increased slightly, and the difference was statistically significant ( F=22.612, P<0.05), which increased from preoperative 1.97±0.67 to 2.73±0.60 (38.58% increased, t=6.380, P<0.05), 2.82±0.64 (43.15% increased, t=6.926, P<0.05) and 2.74±0.62 (39.09% increased, t=6.368, P<0.05). The volume of thecervical longus of the patients decreased after the operation, and the difference was statistically significant ( F=64.511, P<0.05), which decreased from 8853.48±458.65 mm 3 before the operation to 7834.53±461.59 mm 3 (11.51% decreased, t=11.822, P<0.05), 7926.42±456.24 mm 3 (10.47% decreased, t=10.819, P<0.05), 7892.38±450.78 mm 3 (10.86% decreased, t=11.283, P<0.05). There were no statistically significant differences in the non-surgical segment AxCSA, RLS and the volume of thecervical longus at the 3rd and 12th months after surgery and the last follow-up ( P>0.05). There was no statistically significant difference of CESA and CESA/VBA compared to preoperative in the surgical segment and non-surgical segment ( P>0.05). Pearson correlation analysis showed that the volume of cervical longus and VAS at the 3rd month ( r=-0.308, P<0.05), the 12th month ( r=-0.210, P<0.05) and the last follow-up ( r=-0.404, P<0.05) were negatively correlated; Among the volume of cervical longus and NDI in the 3rd month ( r=-0.511, P<0.05), 12th month ( r=-0.518, P<0.05) and the last follow-up ( r=-0.352, P<0.05), there was a negative correlation; However, there was no statistically significant correlation between the cervical longus muscle volume and mJOA at each follow-up time point ( P>0.05); There was no significant correlation between CESA/VBA and VAS, NDI, and mJOA at the 3rd, 12th and last follow-up ( P>0.05). Conclusion:The volume and morphology of cervical longus after ACDF was significantly reduced compared with that before the operation, but the volume and morphology of the cervical extensor muscle did not change significantly. ACDF surgery mainly affects the cervical longus corresponding to the surgical segment, and the volume is negatively correlated with the VAS and NDI during follow-up.

ABSTRACT

Exosomes are vesicles with a double globular membrane of lipids that can be secreted by a variety of cells, including stem cells. Exosomes have unique biological characteristics and irreplaceable powerful functions which play an important role in intercellular communication. The various cytokines, signal proteins, lipids and regulatory nucleic acids contained in stem cell exosomes can play a protective role against the injury of kidney, liver, heart, blood vessels and nerves. Stem cell exosomes delay the process of intervertebral disc degeneration by inhibiting the apoptosis of nucleus pulposus cells and increasing the synthesis of extracellular matrix, etc. The mechanism of its role is mainly through miRNA and related signaling pathways. Exosomes contain complex components. Although the mechanism of action of exosomes in intervertebral discs has been preliminarily explored, the components contained in exosomes are complex and the specific situation has not been fully understood, which still needs further study. In this review, the characteristics and functions of stem cell exosomes, extraction, identification and storage methods, the impacttovarious other tissues, as well as the effects on intervertebral discs and their mechanisms were elaborated in order to provide a basis for the study of intervertebral disc degenerative diseases.

ABSTRACT

Objective:To explore the effect of minimally invasivetransforaminal lumbar interbody fusion (MIS-TLIF) on lumbar multifidus muscle using MRI techniqueandits clinical significance.Methods:From September 2016 to July 2019, 23 patients who underwent MIS-TLIF surgery for unilateral symptomatic disc herniation in unilateral segments (L 3,4, L 4,5, L 5S 1) of Qingdao University Affiliated Hospital were studied. Their lumbar MR examination was performed 1 week before surgery, and 3 and 6 months after surgery. The axial section of multifidus muscle cross section area (AxCSA) was measured on the axial T2WI image of each intervertebral disc level before and after the operation. The ratio of long and short lines (RLS) was calculated, andthe ratio of axial section of muscle fat infiltration cross section area (FLSA) and AxCSAwasrecorded as FLSA/AxCSA. The changes of various indexes of multifidus muscle in the affected side and the healthy side of the lumbar spine before and after the operation were compared, and the effect of the MIS-TLIF procedure on the morphology of the multifidus muscle was observed. Magnetic resonance spectroscopy (MRS) measurements of the muscle cross-section of the affected side were performed before and 6 months after the operation. The integral value of intracellular lipid (IMCL) and extracellular lipid (EMCL) of 1H spectrum muscle cells was compared, while the degree of fat infiltration was measured. Results:Patients with single-segment lumbar disc herniation had larger AxCSAin the healthy side than the affected side before surgery in surgical level ( t=6.611, P<0.05), and the muscle AxCSAin the healthy side was larger than the affected side in non-surgical levels ( t=-6.682, P<0.05), both suggested preoperative muscle volume advantage in the healthy side; no difference in bilateral AxCSA at 3 months was found after surgeryin surgical levels ( t=0.197, P> 0.05)and non-surgical levels ( t=-1.631, P> 0.05), which suggested bilateral muscle volume equal advantageat short-term follow-up. The FLSA/AxCSA of affected segment before and after 3 months was 9.5%±3.8% and 8.7%±1.5%, and the difference was statistically significant ( t=3.163, P<0.05); the RLS of affected segment before and after 3 months was 3.3%±0.24% and 2.7%±0.83%, and the difference was statistically significant ( t=3.42, P<0.05). The medians of EMCL/IMCL before and after 6 months of MRS were 2.010 and 1.475, respectively, and EMCL decreased after 6 months ( Z=0.48, P<0.05). Conclusion:Patients with single-segment lumbar disc herniation have different morphology of bilateral multifidus muscle before surgery. MIS-TLIF has little effect on the multifidus muscle of the surgical side. MIS-TLIF significantly reduces extracellular lipid accumulation, promotes intracellular transfer, and increases intracellular fat metabolism. Its retention of muscle attachment points and limited fixation can also reshape compensatory muscle atrophy.

ABSTRACT

Objective To explore the management strategy and indications for revisionary internal fixation after percutaneous kyphoplasty/percutaneous vertebroplasty (PKP/PVP) in cancellous vertebral fractures.Methods A retrospective analysis was made of the 676 cases of single-segment PKP/PVP at Department of Orthopaedics,The Affiliated Hospital to Qingdao University from January 2008 to January 2019.They were subjected to 4 different managements after their primary PKP/PVP:rehabilitation without any treatment in 637 cases,conservative treatment in 19 cases (including 3 ones who refused any revision),KP/VP revision in 12 cases and internal fixation revision in 8 cases.The rate of volume reduction after bone cement dispersion (Vx) was calculated using software Mimics 17.0 on the basis of primary CT data of all the patients.The correlation regression analysis was made between the revision rate and the approximate quantization value of Vx.The Glasgow Coma Score (GCS) of conscious state was used to evaluate the 39 patients after failure of their primary surgery before the surgical strategy for revision was worked out.The cobb angle,pelvic incidence angle (PI),pelvic inclination angle (PT),sacral inclination angle (SS),sagittal deviation (SVA),pain visual analogue scale (VAS) were measured and recorded before operation and at the last follow-up for the KP/VP revision group and internal fixation revision group,indicated as △cobb,△PI,△PT,△SS,△SVA and △VAS,respectively.The indexes were compared between the 2 groups.Results The incidence of osteoporotic vertebral fractures treated with internal fixation revision was 1.18% (8/676).The correlation between Vx and revision rate was y =0.53 + 0.04x (P < 0.05).The regression analysis showed that Vx was positively correlated with the revision rate (r2 =0.860,P =0.001) and the fitting curve was correlated (r2 =0.916,P =0.001).The GSC scores revealed 31 normal,6 mild disturbance and 2 moderate disturbance cases.There were no significant differences in gender,age or VAS scores between the KP/VP revision group and the internal fixation revision group (P > 0.05).There was a significant difference in △cobb between the 2 revision groups (6.3° ± 7.5° versus 19.2° ± 14.8°) (P <0.05),but there were no significant differences between the 2 groups in △PI (4.1°±5.2° versus 3.3°±6.7°),△PT (0.7°±4.6° versus 0.4° ± 3.2°),△SS (3.7° ± 6.2° versus 3.1° ± 5.3°) or △SVA (-3.2 ± 11.9 mm versus-7.9 ± 9.5 mm) (P > 0.05).Conclusions The outcomes of primary PKP/PVP have a great impact on the decision-making of internal fixation revision.The mode and extent of diffusion after initial vertebral cement perfusion are particularly related to the revision rate.The revision plan should depend on clinical symptoms.The internal fixation revision should be individualized to ensure the quality of life of the patients in line with the principles of "resolving symptoms" and "moderate correction".

ABSTRACT

Objective To investigate the relationship between serum secreted phospholipase A2 (sPLA2) and the severity of the disease in cobra bite patients. Methods Fifty-two cobra bite patients admitted to our hospital from January 2015 to December 2015 were selected according to the inclusion and exclusion criteria. According to the degree of disease, patients were divided into the light and heavy risk groups. According to the degree of swelling of the affected limbs, patients were divided into the mild swelling group and moderate-severe swelling group. According to the time difference between visits, patients were divided into: visit time <8 h group and visit time ≥ 8 h group. Twenty healthy adult volunteers served as the control group. The levels of serum sPLA2, C reactive protein (CRP), D-dimer (DD), lactic acid (LAC) and peripheral blood leukocyte count (WBC) were measured and compared in different groups. Quantitative data were analyzed using t test and rank sum test. Results The levels of serum sPLA2 in the light and heavy risk group were statistically different from those in the control group (P<0.05), and were statistically significant between the light and heavy risk groups (P<0.01) and between the mild swelling group and moderate-severe swelling group (P<0.05). The serum sPLA2 levels in group A and group B were also significantly different from those in the control group (P<0.05). The level of sPLA2 was positively correlated with the level of LAC, DD and WBC, and the correlation coefficients were 0.3142, 0.2752 and 0.6534, respectively. Conclusions The higher the level of serum sPLA2, the more serious the patient's poisoning symptoms. It is of certain clinical value to evaluate the condition of cobra.

ABSTRACT

Background:Ulcerative colitis (UC)is a chronic inflammatory disorder. Studies have shown that intestinal injury of UC is related to changes of tight junction proteins. Aims:To investigate the expressions and localizations of tight junction protein claudin-1,-2,-4. Methods:Forty female Wistar rats were randomly divided into normal control group and model group. Rats in model group received 7. 5 mg/ mL oxazolone enema to induce experimental colitis. Rats received 0. 9%NaCl solution enema were served as normal controls. Macroscopic score and histological score were assessed. ELISA was used to determine serum and colon tissue inflammatory factor TNF-α,IL-4,IL-5,IL-10 levels. Protein expressions of tight junction protein claudin-1,-2,-4 were measured by immunohistochemistry and Western blotting. mRNA expressions of claudin-1,-2,-4 were determined by real-time PCR. Results:Compared with normal control group,macroscopic score and histological score were significantly increased (P < 0. 05),serum and colon tissue IL-4 and IL-5 levels were significantly increased (P < 0. 05)in model group,however,no significant differences in TNF-α and IL-10 levels were found between the two groups (P > 0. 05). mRNA and protein expressions of claudin-1,-4 were significantly decreased in model group than in normal control group (P < 0. 05),while mRNA and protein expressions of claudin-2 were significantly increased (P < 0. 05). Conclusions:Changes of distributions and expressions of tight junction protein claudin-1,-2,-4 are found in experimental colitis rats,which may lead to impaired epithelial barrier,and might be served as potential target for treatment of UC.

ABSTRACT

Objective To evaluate the effect of single-nucleotide polymorphisms at the miRNA binding site rs3660 in the 3'-untranslated region of the KRT81 gene (miR-SNPs) on the cancer risk and clinical prognosis of non-Hodgkin's lymphomas (NHL).Methods The single-nucleo-tide polymorphisms of rs3660 was genotyped with ligation detection reaction method.The association of rs3660 with NHL survival was calculated with log-rank test using Kaplan-Meier method.Multivariate survival analysis was performed using a Cox proportional hazards model.Results The rs3660 genotype distribution difference was not statistically significant between the case and control group (P =0.50).Patients carrying the rs3660 CG/CC genotype exhibited a significantly longer survival time than patients carrying the GG genotype (P =0.012).In addition,rs3660 was associated independently with the survival of NHL patients in multivariate analysis (RR=0.589,95% CI:0.415-0.832,P =0.004).The association of this miR-SNP with NHL survival was further confirmed in the peripheral T cell lymphoma (PTCL) subtype.Conclusion Our results indicate that KRT81 rs3660 GG type is an independent prognostic marker in NHL.
