Metallic artifact suppression with MAVRIC-SL in magnetic resonance imaging for assessing chronic pain after hip or knee arthroplasty / Supressão do artefato metálico na ressonância magnética com MAVRIC-SL na avaliação da dor crônica em artroplastia de quadril ou joelho

Abstract Objective: To analyze the association between osteolysis at the prosthesis interfaces, as determined by magnetic resonance imaging (MRI) with multiacquisition variable-resonance image combination selective (MAVRIC-SL) sequences, and clinical severity after knee or hip arthroplasty, as well as to assess interobserver and intraobserver agreement on periprosthetic bone resorption. Materials and Methods: This was a cross-sectional study of 47 patients (49 joints) under postoperative follow-up after knee or hip arthroplasty, with chronic pain, between March 2019 and August 2020. All of the patients completed the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) questionnaire. The component interfaces were evaluated and ordered into two groups: osseointegrated and osteolytic. Nonparametric tests were used. Results: There were significant differences between the two groups in terms of the mean WOMAC scores: total (p = 0.010); stiffness domain (p = 0.047); and function (p = 0.011) domains. There was substantial interobserver and intraobserver agreement for most analyses of the components. Conclusion: Periprosthetic osteolysis appears to be associated with clinical complaints of pain in the post-arthroplasty scenario, and MAVRIC-SL provides reproducible assessments. It could prove to be an important tool for orthopedists to use in the evaluation of challenging cases of chronic pain after arthroplasty.

Resumo Objetivo: Analisar associação entre osteólise nas interfaces protéticas por ressonância magnética com sequências MAVRIC-SL e a gravidade clínica dos pacientes submetidos a artroplastias de joelho ou quadril. Determinar concordância intraobservador e interobservador na reabsorção óssea peri-implante. Materiais e Métodos: Foi realizado estudo transversal entre março de 2019 e agosto de 2020, com 47 pacientes (49 articulações) em seguimento pós-operatório de artroplastias de joelho ou quadril, com dor crônica, que responderam ao questionário WOMAC. As interfaces dos componentes foram avaliadas e definiram dois grupos: osteointegrado e osteólise. Testes não paramétricos foram usados. Resultados: Houve diferença significativa na média do escore WOMAC entre os grupos (p = 0,010), assim como nos domínios rigidez (p = 0,047) e função (p = 0,011). Houve concordância substancial interobservador e intraobservador para a maioria dos componentes analisados. Conclusão: Osteólise periprótese parece estar associada com a queixa clínica de dor pós-artroplastia, com avaliação reprodutível pela MAVRIC-SL. Isto pode ser uma importante ferramenta para o ortopedista na avaliação de casos desafiadores de dor crônica pós-artroplastia.

Correlation between body mass index and joint pain intensity with gait performance in individuals with osteoarthritis / Correlação entre o índice de massa corporal e intensidade da dor articular com o desempenho da marcha em indivíduos com osteoartrite

ABSTRACT BACKGROUND AND OBJECTIVES: Individuals with osteoarthritis (OA) often have joint pain and are overweight or obese. Thus, the objective of this study was to observe whether there is correlation between body mass index and joint pain intensity with gait performance in individuals with OA. METHODS: Cross-sectional study, which evaluated 60 volunteers, being 30 with clinical diagnosis of knee osteoarthritis and 30 without the disease, of both sexes and aged between 50-82 years. Joint pain intensity was assessed using the Visual Analog Scale, gait-related functional tasks using the Dynamic Gait Index, and the functional mobility using the Timed Up and Go test. RESULTS: There was a correlation between overweight/obesity and high levels of joint pain intensity (p=0.018), with worse performance in gait-related functional tasks (p=0.000) and with worse functional mobility (p=0.034) only for the individuals with OA. High levels of joint pain intensity also correlated with worse performance in the gait-related functional tasks (p=0.000) in the OA group, and also with worse functional mobility in the OA group (p=0.001) and also in the group of individuals without the disease (p=0.032). CONCLUSION: This study identified a correlation between overweight/obesity and high levels of joint pain intensity and worse gait performance in individuals with osteoarthritis. High levels of pain intensity also correlated with worse gait performance in individuals with OA.

resumo JUSTIFICATIVA E OBJETIVOS: Indivíduos com osteoartrite (OA) frequentemente apresentam dor articular e sobrepeso ou obesidade.

MÉTODOS: Estudo de corte transversal, que avaliou 60 indivíduos, sendo 30 com diagnóstico clínico de osteoartrite de joelho e 30 sem a doença, de ambos os sexos e com faixa etária entre 50 e 82 anos. A intensidade da dor articular foi avaliada pela Escala Analógica Visual, as tarefas funcionais relacionadas à marcha pelo Dynamic Gait Index e a mobilidade funcional pelo teste Timed Up and Go. RESULTADOS: Houve correlação entre o sobrepeso/obesidade e níveis elevados de intensidade da dor articular (p=0,018), com um pior desempenho nas tarefas funcionais relacionadas à marcha (p=0,000) e com menor mobilidade funcional (p=0,034) apenas para os indivíduos com OA. Os níveis elevados de intensidade de dor articular também mostraram correlação com um pior desempenho nas tarefas funcionais relacionadas à marcha (p=0,000) no grupo com OA, e ainda, com uma menor mobilidade funcional no grupo com OA (p=0,001) e também no grupo de indivíduos sem a doença (p=0,032). CONCLUSÃO: Este estudo identificou correlação entre o sobrepeso/obesidade com níveis elevados de intensidade da dor articular e com um pior desempenho na marcha nos indivíduos com OA. Os elevados níveis de intensidade da dor também mostraram correlação com pior desempenho na marcha nos indivíduos com OA.

Radiographic findings in acromegaly: pictorial essay / Achados radiográficos da acromegalia: ensaio iconográfico

Abstract Acromegaly is an uncommon metabolic disorder, often diagnosed after a long delay. One symptom seen in many patients with acromegaly is arthralgia, a finding that calls for the use of conventional radiography, which can reveal subtle changes that can go unnoticed. The objective of this pictorial essay is to portray the radiographic aspects of acromegaly, seeking to demonstrate the importance of conventional radiography, which, despite its simplicity, can suggest the diagnosis, even in the early stages, thus altering the clinical course of the disease.

Resumo A acromegalia é um distúrbio metabólico pouco frequente, muitas vezes apresentando grande atraso diagnóstico. A artralgia é um dos sintomas mais comumente encontrados nos pacientes acromegálicos, motivando a realização de radiografias convencionais, as quais podem apresentar achados sutis que podem passar despercebidos. O objetivo deste ensaio é retratar os achados radiográficos da acromegalia, buscando demonstrar a importância deste método que, apesar de simples, pode sugerir o diagnóstico, mesmo em fases iniciais, alterando assim o curso clínico da doença.

Effect of Danggui Niantongtang on Intestinal Flora in Adjuvant-induced Arthritis Rats of Wind-dampness-heat Arthralgia：Based on 16S rDNA Sequencing / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Danggui Niantongtang （DGNTT） against adjuvant-induced arthritis （AA） in rats with wind-dampness-heat arthralgia （FSR） based on the variation of intestinal flora. MethodA total of 60 SD rats were randomized into normal （control） group， FSR group， low-， medium-， and high-dose DGNTT （5.67， 11.34， 22.68 g·kg-1） groups， and methotrexate （MTX） group （1.35 mg·kg-1）， with 10 rats in each group. The rats， except the control group， were injected with Mtb adjuvant and then exposed to artificial climatic chamber （hot and humid with wind） for 64 h for modeling. The rats were treated with water， DGNTT or MTX for 28 days from the day of injection. Arthritis index （AI） of rats was measured and paw volume was determined with a volume meter. The morphology of synovial tissues of the knees was observed based on hematoxylin-eosin （HE） staining and the changes of intestinal flora were analyzed based on 16S rRNA sequencing. ResultDGNTT can alleviate the hyperplasia of synovial tissue and inflammation of AA rats with FSR and inhibit the formation of pannus. The results of 16S rRNA sequencing showed that the relative abundance of Firmicutes， Lactobacillus， Prevotella 9， and Alloprevotella decreased （P<0.05， P<0.01） and the relative abundance of Bacteroidetes and Bacteroides increased （P<0.01） in FSR group compared those in the control group. Compared with the FSR group， all DGNTT groups and MTX group had high relative abundance of Lactobacillus （P<0.05， P<0.01） and low relative abundance of Bacteroidetes （P<0.01） and medium-dose and high-dose DGNTT groups and MTX group showed high abundance of Firmicutes， Prevotella 9， and Alloprevotella and low abundance of Bacteroides （P<0.05， P<0.01）. Spearman's correlation analysis suggested that the abundance of Bacteroides and Helicobacter was in positive correlation with AI （P<0.05）， while the abundance of Prevotella 9 and Candidatus Saccharimonas was in negative correlation with AI （P<0.01， P<0.05）. There was a negative correlation between the abundance of Prevotella 9 and paw volume （P<0.01）， and the abundance of Ruminococcaceae NK4A214 group， Christensenellaceae R-7 group， and Bacteroides was in negative correlation with spleen index （P<0.05）. The abundance of Prevotella 9 was in negative correlation with spleen index （P<0.01）. ConclusionDGNTT is effective for arthritis with FSR， as it can regulate the composition of intestinal flora in AA rats by increasing the abundance of probiotics and inhibiting the growth of pathogenic bacteria. The mechanism is the likelihood that it improves intestinal immune metabolism to ensure intestinal homeostasis.

To explore the quality markers of Huangqin Qingre Chubi capsule in the treatment of rheumatoid arthritis based on network pharmacology combined with pharmacokinetics and target verification / 药学学报

As an effective prescription for the treatment of rheumatoid arthritis (RA), Huangqin Qingre Chubi capsule (HQC) is still blank in quality control. This study aims to explore quality markers (Q-markers) for HQC in the treatment of RA by integrating network pharmacology and pharmacokinetics. By constructing the visualization network of "pharmacodynamic ingredient-target-pathway", the potential Q-Marker of HQC treatment for RA was preliminatively predicted. A rat model of rheumatic heat obstruction syndrome collagene-induced arthritis (CIA) was established to elucidate the dynamic quantification law of pharmacodynamic components of HQC in the disease state of rats. To establish the inflammatory model of RA synovial fibroblasts (MH7A) induced by tumor necrosis factor-α (TNF-α) in vitro. The effects of active ingredients on protein expression of sphingosin kinase-1 (Sphk1) and p-SphK1 were detected. The network pharmacological results showed that baicalin, geniposide, luteolin, coixol and amygdalin were the important active components of HQC treatment for RA. Quantitative analysis results further verified the measurability of these five components. The expression of Sphk1 and p-SphK1 was significantly inhibited by geniposide and baicalin by Western blotting. The above studies determined that the above 5 components could be used as Q-markers in the treatment of RA by HQC. This experiment was approved by the Experimental Animal Ethics Committee of Anhui University of Chinese Medicine (approval number: AHUCM-rats-2021049). All procedures were conducted in strict accordance with the principles of animal use and care.

Investigation of pharmacological characteristics and mechanisms of Qufeng Gutong Cataplasm based on a "disease-syndrome-symptom-formula" association network analysis / 药学学报

Growing clinical evidence shows that Qufeng Gutong Cataplasm may exert a significant analgesic effect. However, the pharmacological characteristics and mechanisms underlying this prescription are still unclear. In the current study, a "disease-syndrome-symptom-formula" association network analysis was performed to explore the pharmacological characteristics and mechanisms of Qufeng Gutong Cataplasm against osteoarthritis (OA), neuropathic pain (NP), chronic inflammatory pain (CIP) and myofascial pain syndrome (MPS) by integrating clinical phenomics data, transcriptomics data and biological interaction network mining. As a result, the three functional modules (Qufeng Sanhan-QFSHG, Shujin Huoxue-SJHXG and Xiaozhong Zhitong-XZZTG) enriched by the drug network targets were all related to the pharmacological effects of Qufeng Gutong Cataplasm, including dispersing cold and relieving pain, activating blood and relieving pain, reducing swelling and relieving pain. In addition, the main pharmacological effects of QFSHG and XZZTG were dispelling wind and dispersing cold and dehumidifying, promoting Qi and reducing swelling and relieving pain, respectively. In terms of reversing the imbalance of "immune-inflammation-vascular axis", the main pharmacological effects of SJHXG were regulating the liver and promoting Qi, activating blood circulation and removing stasis. Mechanically, the key network targets of Qufeng Gutong Cataplasm against OA, NP, CIP and MPS may play a therapeutic role in relieving hyperalgesia and paresthesia by reversing the "neuro-endocrine-immune" imbalance system during the occurrence and progression of diseases. In conclusion, our data indicate that Qufeng Gutong Cataplasm may relieve the pain and wind-cold-dampness arthralgia syndrome related symptoms by regulating the "neuro-endocrine-immune" system, neurological and endocrine disorders and reversing the imbalance of "immunity-inflammation". The relevant results may provide a network-based evidence for clinical positioning of Qufeng Gutong Cataplasm, and offer a direction for further clinical and experimental validation.

The impact of Chikungunya chronic arthralgia on women's upper limbs motor function: a cross-sectional study / O impacto da artralgia crônica pós-Chikungunya na função motora dos membros superiores de mulheres: um estudo transversal / El impacto de la artralgia crónica poschikunguña en la función motora del miembro superior de mujeres: un estudio transversal

ABSTRACT Post-Chikungunya chronic arthralgia (PCCA) may lead to musculoskeletal repercussions and functional loss. The objective was to assess the upper limb physical disability and symptoms during daily, work, and leisure activities of women presenting PCCA compared to healthy controls (HC). This was a cross-sectional study conducted with 52 women. The participants were divided into PCCA (37) and HC (15) groups. Handgrip strength, range of motion, level of pain (numerical rating scale), and participants' physical disability and symptoms (Disabilities of the Arm, Shoulder, and Hand Questionnaire - DASH) were evaluated. Differences between groups were evaluated using the Students t-test and Pearson's correlations. The chi-square test was applied for categorical variables. The significance was set at α=0.05. The disease duration was 19.5±13.1 months. We found no differences between groups for peak force (PCAA:23.6±7.4kgf; HC: 24.5±6.2kgf; p=0.676). The results showed a significant difference between groups regarding range of motion (PCCA: 63.5±17.3o; HC: 77.2±9.6o), level of hand pain (PCCA: 5.8±2.2; HC: 0.4±1.5), and upper limbs functional levels (PCCA: 44.5±17.4; HC: 16.2±20.5). Participants related severe difficulty or inability to perform tasks such as opening a jar (78.4%), placing objects above head height (48.7%), doing heavy household chores (56.8%), and gardening (51.4%). Impairment in the upper limb physical function in daily, work, and leisure activities shows the higher prevalence in the long-term.

RESUMO A artralgia crônica pós-Chikungunya (ACPC) pode gerar repercussões musculoesqueléticas e perda funcional. Nesse sentido, o objetivo deste estudo foi avaliar a incapacidade física e os sintomas de membros superiores de mulheres com ACPC durante atividades diárias, laborais e de lazer comparadas aos controles saudáveis (CS). Para tanto, realizou-se um estudo transversal conduzido com 52 mulheres. As participantes foram divididas entre os grupos com ACPC (37) e CS (15). Foram avaliados força de preensão, amplitude de movimento (ADM), nível de dor (escala numérica de dor) e incapacidade física e sintomas por meio do Disabilities of the Arm, Shoulder and Hand Questionnaire (Dash). Diferenças entre os grupos foram avaliadas pelo teste t de Student e correlações de Pearson. O teste qui-quadrado foi utilizado para variáveis categóricas e α=0,05 foi estabelecido como nível de significância. Verificou-se que a duração da ACPC foi de 19,5±13,1 meses. Não houve diferença entre os grupos para a força pico (ACPC: 23,6±7,4kgf; CS: 24,5±6,2kgf; p=0,676). Os resultados demonstraram diferença significativa entre os grupos em termos de ADM (ACPC: 63,5±17,3o; CS: 77,2±9,6o), nível de dor nas mãos (ACPC: 5,8±2,2; CS: 0,4±1,5) e níveis funcionais dos membros superiores (ACPC: 44,5±17,4; CS: 16,2±20,5).

Clinical Signs and Symptoms Associated with COVID-19: A Cross Sectional Study

ABSTRACT: Covid-19 is a viral disease that has spread throughout the world, becoming a pandemic. Dysgeusia and anosmia are some of its most frequent symptoms. The aim of the study was to determine the frequent signs and symptoms associated with COVID-19 patients. A cross-secional study from 370 patients with acute respiratory illness admitted by emergenc y services of a hospital in Acapulco. An institutional survey was applied to all patients as a data collection instrument, and a SARS-CoV-2 test, by RT-PCR processed by a certified laboratory. Statistical analysis was performed using the STATA V13 program. The numerical variables without normality were reported in medians, 25th and 75th percentiles, and the Mann W ithney U test was performed for differences between groups. The categorical variables were presented in percentages and differences between groups with Chi-square test. A generalized linear models (GLM) analysis was carried out to determine the most frequent symptoms and signs associated with COVID-19. Clinical signs and symptoms associated to COVID-19 in the bivariate análysis were dysgeusia, odynophagia, anosmia, arthralgia, myalgia, conjunctivitis, and age older than 40 years. In the final multivariate model only age older than 40 years (OR) 2.2; CI 95 % 1.3,3.8) and dysgeusia (OR 2.1; CI95 % 1.2,3.6) kept significance. Dysgeusia, odynophagia, anosmia, arthralgia, myalgia and conjunctivitis are clinical signs and symptoms that can appear in the early stages of the disease, so they could be important for an early diagnosis.

Diagnóstico clínico y por imagen de rodilla de Charcot por neuroartropatía diabética

RESUMEN Introducción: La neuroartropatía es una afección secundaria a enfermedades metabólicas, infecciosas o genéticas. Su localización usual está reportada en el pie, pero puede afectar cualquier articulación, compromete su estado vascular y modifica la condición ósea, genera fracturas, contracturas y luxaciones. Objetivos: Reportar los hallazgos clínicos e imagenológicos de una paciente con neuroartropatía de Charcot por diabetes mellitus, en una localización articular, poco frecuente. Caso Clínico: Paciente femenina de 62 años, procedente del suroccidente colombiano, con antecedentes de diabetes mellitus y complicaciones micro y macrovasculares. Presentó un cuadro clínico de dolor articular en la rodilla derecha, que evolucionó a una imposibilidad para la marcha. En su atención se realizaron diferentes estudios de imagen; se encontró una fractura del cóndilo femoral izquierdo y de los platillos tibiales. Estas características radiológicas típicas, más los cambios clínicos de la articulación, llevaron al diagnóstico de rodilla de Charcot. Se realizaron intervenciones farmacológicas analgésicas, además de inmovilización articular, con adecuada evolución en el seguimiento clínico. Conclusiones: La neuroartropatía con rodilla de Charcot es una afección que debe ser evaluada en todos los pacientes con diabetes mellitus y otras enfermedades, ampliar el panorama de revisión articular a localizaciones menos frecuentes, como la rodilla. Una intervención temprana y multidisciplinaria puede favorecer los desenlaces clínicos positivos.

ABSTRACT Introduction: Neuroarthropathy is a condition secondary to metabolic, infectious, or genetic diseases. Its usual localization is reported in the foot, but it can affect any joint, compromising its vascular status and modifying the bone condition generating fractures, contractures, and dislocations. Objectives: To report the clinical and imaging findings of a patient with Charcot neuroarthropathy due to diabetes mellitus in a rare joint location. Clinical Case: A 62-year-old woman from Colombian southwestern, with a history of diabetes mellitus, in addition to micro and macrovascular complications. She presented a clinical picture of joint pain in the right knee that evolved to an inability to walk. During her care, different imaging tests were performed, finding a fracture of the left femoral condyle and tibial plateau, these typical radiological characteristics plus the clinical changes of the joint, led to the diagnosis of Charcot's knee. Pharmacological interventions were performed in pain in addition to joint immobilization, with adequate evolution in clinical follow-up. Conclusions: Neuroarthropathy is a condition that should be evaluated in all patients with diabetes mellitus and other conditions, expanding the joint revision panorama to less frequent locations such as the knee; early and multidisciplinary intervention can favor positive clinical outcomes.

Radiographic aspects in individuals infected by human T-lymphotropic virus type 1 (HTLV-1) with joint pain

Abstract Background: Joint pain in the absence or with little synovitis is observed in a large percentage of HTLV-1 infected subjects. As the virus infect CD4 +and CD8 +positive, macrophages and B cells an exaggerated production of pro-inflammatory cytokines is detected in these patients. However, the possible association of HTLV-1 infection with autoimmune diseases has not been documented definitively and the clinical characteristics of HTLV-1 associated arthropathy has not been defined. The objective this study is to describe clinic and radiographic features in HTLV-1-infected individuals with complaints of joint pain. Methods: Cross-sectional study enrolling HTLV-1-infected individuals with chronic joint pain, aged up to 75 years, both genders and seronegative controls with osteoarthritis. All participants underwent conventional radiography of the hips, knees and ankles. Results: Eighty-one HTLV-1 infected patients and 30 subjects with osteoarthritis participated in the study. Polyarticular and symmetrical arthritis prevailed in the HTLV-1 positive group (54%), while oligoarticular and asymmetrical (44%) were more common in controls ( p < 0.05). The frequency of enthesophytes (90%) in HTLV-1-infected patients was greater than in the control group (73%) ( p < 0.05). Radiographic features were similar in HTLV-1 carriers and in patients with probable or definite HTLV-1 associated myelopathy. The presence of enthesophytes in the absence of joint space reduction or osteophytes was only observed in HTLV-1-infected individuals ( p < 0.001). Magnetic resonance imaging of the ankles of five HTLV-1-infected patients and five controls demonstrated a higher frequency of enthesitis, bursitis and osteitis in the HTLV-1 infected group. Conclusion: HTLV-1-associated arthropathy is clinically characterized by symmetrical polyarthralgia and the main radiological finding is the presence of enthesophytes in the absence of osteophytes and joint space narrowing.

Efficacy and influential factors of opening wedge high tibial osteotomy for the treatment of knee osteoarthritis / 中国基层医药

Objective:To investigate the efficacy of opening wedge high tibial osteotomy (OWHTO) in the treatment of knee osteoarthritis, and analyze the related factors that affect its clinical efficacy.Methods:The clinical data of 80 patients with knee osteoarthritis who underwent OWHTO between December 2016 and May 2020 in Hospital of the Marine Police Corps of the Chinese People's Armed Police Force were retrospectively analyzed. These patients were divided into effective group ( n = 76) and ineffective group ( n = 4) according to clinical efficacy. The Visual Analogue Scale (VAS), the Hospital for Special Surgery Knee Score (HSS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) were used to assess the severity of knee osteoarthritis before and 3 months after surgery. The influential factors of clinical efficacy were analyzed. Results:VAS score, WOMAC score, HSS score, joint pain, joint function, joint range of motion, muscle strength, and flexion deformity of 80 patients post-surgery were improved compared with those pre-surgery ( t = 24.92, 21.45, 52.62, 15.87, 10.88, 15.28, 42.54, 11.07, all P < 0.05). After surgery, excellent outcomes were observed in 29 (36.25%) patients, good outcomes in 34 (42.50%) patients, fair outcomes in 13 (16.25%) patients, and poor outcomes in 4 (5.00%) patients. Body mass index, preoperative VAS score, and preoperative WOMAC score in the effective group were (24.10 ± 3.06) kg/m 2, (5.55 ± 1.57) points, and (36.96 ± 9.62) points, respectively, which were significantly lower than those in the ineffective group [(27.64 ± 3.62) kg/m 2, (7.87 ± 1.39) points, (47.95 ± 9.63) points, t = 2.23, 2.89, 2.22]. HSS score in the effective group was significantly higher than that in the ineffective group [(52.81 ± 3.71) points vs. (46.83 ± 3.69) points, t = 3.14, P < 0.05)]. Body mass index, preoperative VAS score, and preoperative WOMAC score were positively correlated with clinical efficacy ( r = 0.24, 0.31, 0.24, P < 0.05), and preoperative HSS score was negatively correlated with clinical efficacy ( r = -0.33, P < 0.05). Logistic regression analysis was performed to analyze the above markedly related factors. Preoperative HSS score was an independent protective factor of clinical efficacy of OWHTO, and body mass index and preoperative VAS score were risk factors of clinical efficacy of OWHTO. Conclusion:OWHTO can greatly improve knee function of patients with knee osteoarthritis and reduce postoperative pain. It should be noted that excessive obesity may affect the clinical efficacy of OWHTO, and preoperative VAS score and WOMAC score should be controlled in patients with excessive obesity.

Mechanism of Danggui Niantongtang on Adjuvant Arthritis Rats with Wind-dampness-heat Arthralgia Based on Quantitative Proteomics / 中国实验方剂学杂志

ObjectiveTo explore the mechanism of Danggui Niantongtang （DGNT） against adjuvant arthritis （AA） rats with wind-dampness-heat arthralgia by quantitative proteomics. MethodSixty SD rats were randomly divided into normal group， model group， angelica came pain soup low， medium and high dose group and methotrexate （MTX） group， each group of 10， only the rat tail root subcutaneously inactivated mycobacterium tuberculosis （Mtb） of adjuvant to build model of AA， artificial climate box intervention 16 d rheumatic fever bi syndrome model is set up， building the day began to drug intervention， The intervention lasted for 28 days. The proteins of synovial tissues in experimental rats were extracted. The differential proteins in the medium-dose DGNT group and the model group were detected and analyzed by 4D label-free quantification （4D-LFQ） proteomics. The differentially expressed proteins associated with mitochondrial pathway apoptosis were verified by immunohistochemistry and Western blot. ResultA total of 4 756 proteins were identified from rat synovial tissues， of which 4 234 proteins contained quantitative information. There were 814 differential proteins between the model group and the DGNT group. As revealed by Gene Ontology （GO） and Kyoto Encyclopedia of Gene and Genome （KEGG） enrichment analyses， DGNT had an effect on the synovial proteome of AA rats with wind-dampness-heat arthralgia， and the differential proteins were enriched in the regulation of the immune system， response to acute inflammation， and apoptosis regulation. As demonstrated by the results of immunohistochemistry and Western blot， compared with the model group， the DGNT groups and the MTX group showed increased protein expression of B-cell lymphoma 2 （Bcl-2）-associated X protein （Bax） and cytochrome C （Cyt C）（P<0.05， P<0.01）， reduced Bcl-2 level （P<0.05， P<0.01）， elevated level of cleaved cysteinyl aspartate-specific protease 9 （Caspase-9）/Caspase-9 （P<0.01）， and decreased level of phosphorylated protein kinase B （p-Akt）/Akt（P<0.05， P<0.01）. ConclusionDGNT involved multiple targets in the treatment of AA with wind-dampness-heat arthralgia and it may exert its effect in the prevention and treatment by regulating the Akt/Bax/Bcl-2 pathway and promoting the cell apoptosis in the mitochondrial pathway.

Expression of LINC00638 in rheumatoid arthritis patients with damp-heat obstruction syndrome and the regulatory mechanisms for inflammation and oxidative stress / 中南大学学报(医学版)

OBJECTIVES@#Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation and joint destruction. Both inflammatory response and oxidative stress contribute to the pathogenesis of RA. Oxidative damage can induce and aggravate the imbalance of immune inflammation and promote cell and tissue damage. In this study, the expression of long non-coding RNA (lncRNA) LINC00638 in peripheral blood of patients with RA damp-heat arthralgia syndrome was observed, and the correlation between LINC00638 and disease activity, immune inflammation and oxidative stress indicator was investigated. Subsequently, the mechanisms for LINC00638 in regulating the inflammatory response and oxidative stress in RA fibroblast-like synoviocyte (FLS) under the condition of overexpression and interference were further explored.@*METHODS@#In this study, 48 RA patients with damp-heat arthralgia syndrome and 27 normal healthy subjects, who came from Department of Rheumatology, First Affiliated Hospital of Anhui University of Chinese Medicine, were included; and they were divided into a RA group and a control group. The expression of LINC00638 in peripheral blood mononuclear cells (PBMC) from the subjects was detected by real-time PCR. Enzyme linked immunosorbent assay (ELISA) was used to detect serum interleukin (IL)-10, IL-17, tumor necrosis factor-α (TNF-α), malondialdehyde (MDA), heme oxygenase 1 (HO-1) and superoxide dismutase 2 (SOD2) expression. Spearman method was used to study the relationship between LINC00638 and erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (anti-CCP), and to observe the relation between LINC00638 and the Disease Activity Score of 28 Joint (DAS28), Quantitative Score of Damp Heat Syndrome, Visual Analogue Scale (VAS), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS). RA-FLS was induced by RA-PBMC, and the RA in vitro cell experimental model was established. LINC00638 overexpression plasmid and small interfering RNA (siRNA) were constructed and transfected into RA-FLS. The cell experiments were divided into 4 groups: a pcDNA3. 1- control group, a pcDNA3.1-LINC00638 group, a siRNA-control group, and a siRNA-LINC00638 group. The transfection efficiency of overexpression plasmid and siRNA was detected by real-time PCR, the expression of TNF-α and IL-10 was detected by ELISA, and the expression of antioxidant proteins HO-1 and SOD2 was detected by immunofluorescence.@*RESULTS@#Compared with the control group, the expression of LINC00638 in the RA group was lower (P<0.01). The area under the curve (AUC) of the receiver operating characteristic (ROC) curve of LINC00638 was 0.9271. The DAS28 in RA group was 5.70 (5.40-6.50), the Quantitative Score of Damp-heat Syndrome was 20.0 (17.0-23.0), and the VAS score was 7.0 (6.3-8.0). Compared with the control group, the ESR, CRP, RF, anti-CCP, SAS and SDS scores in the RA group were significantly increased (all P<0.01). Spearman correlation analysis showed that: LINC00638 was negatively correlated with ESR (r=-0.532, P<0.01), CRP (r=-0.367, P<0.05), TNF-α (r=-0.375, P<0.01), MDA (r= -0.295, P<0.05), DAS28 (r=-0.450, P<0.01), and which was positively correlated with SOD2 (r=0.370, P<0.05). After the induction of RA-FLS, the expression level of LINC00638 was significantly decreased (P<0.01), indicating that the stimulation of PBMC could effectively reduce the expression of LINC00638 in RA-FLS, so the experimental model of RA-FLS-induced by PBMC was utilized. Compared with the pcDNA3.1-control group, the expressions of LINC00638, IL-10, SOD2, and HO-1 in the pcDNA3.1-LINC00638 group were significantly increased (all P<0.01), and the expression of TNF-α was decreased (P<0.01). Compared with siRNA-control group, LINC00638, IL-10, SOD2 and HO-1 in the siRNA-LINC00638 group were significantly decreased (all P<0.01), and TNF-α was significantly increased (P<0.01).@*CONCLUSIONS@#LINC00638 is down-regulated in the peripheral blood of RA patients with damp-heat arthralgia syndrome, which is correlated with disease activity, immune inflammation and oxidative stress. Overexpression of LINC00638 can down-regulate pro-inflammatory factors, up-regulate anti-inflammatory factors, and increase antioxidant enzyme activity, thereby improving inflammation and oxidative stress in RA. LINC00638 is the differential lncRNA obtained by the research group's previous high-throughput sequencing of the whole transcriptome of peripheral blood PBMCs in RA patients and validation of clinical samples. In order to deepen the molecular biology research of this gene, the microRNA and mRNA targeted by LINC00638 can be further studied from the perspective of competing endogenous RNAs.

Diagnosis and treatment of articular manifestations of systemic lupus erythematosus / Diagnóstico y tratamiento de las manifestaciones articulares del lupus eritematoso sistémico

ABSTRACT Articular involvement in Systemic Lupus Erythematosus (SLE) is well recognized as one of the most common manifestations of the disease. This article reviews the recent knowledge of the clinical manifestations, diagnostic techniques and therapies used for the treatment of joint involvement in SLE. The degree of articular involvement is characterized by widespread heterogeneity in terms of clinical presentation and severity. It may range from minor arthralgia without erosions or deformity to erosive arthropathy and severe functional disability. Inflammatory musculoskeletal manifestations are described as a major cause of pain impacting daily activities and as a major determinant of quality-of-life impairment. Thus, physicians must be aware of articular involvement in SLE. Lupus arthritis diagnosis may be challenging, due to the frequently mild synovitis. The introduction of new more sensitive imaging techniques, such as ultrasound, and MRI have contributed significantly to improving the diagnosis of osteoarticular involvement in SLE. There are several treatment options for the management of joint manifestations in patients with SLE. The choice of treatment will depend on the type and pattern of joint involvement, its severity, and the characteristics of the patient.

RESUMEN El compromiso articular en lupus eritematoso sistémico (LES) es bien reconocido como una de las manifestaciones más comunes de la enfermedad. En el presente artículo se revisa la evidencia reciente sobre las manifestaciones clínicas, las técnicas de diagnóstico y los tratamientos utilizados para tratar el compromiso articular en el LES. El grado de compromiso articular se caracteriza por la amplia heterogeneidad en su presentación clínica y su gravedad. Puede variar desde artralgia leve sin erosiones o deformidad, hasta una artropatía erosiva y discapacidad funcional. Se describen las manifestaciones inflamatorias musculoesqueléticas como la principal causa de dolor que afecta las actividades de la vida cotidiana y como uno de los principales factores determinantes del deterioro de la calidad de vida. Por lo tanto, los médicos deben estar conscientes del compromiso articular en LES. El diagnóstico de la artritis lúpica puede ser difícil debido a la sinovitis, usualmente leve. El advenimiento de nuevas técnicas de imágenes más sensibles, como la ecografía y la resonancia magnética, ha contribuido significativamente a mejorar el diagnóstico del compromiso osteoarticular en LES. Existen varias opciones de tratamiento para las manifestaciones articulares en pacientes con LES. La opción de tratamiento dependerá del tipo y del patrón del compromiso articular, así como de las características del paciente.

An Effective Case of Keishikajutsubuto and Maobushisaishinto for Arthritis / 日本東洋医学雑誌

We report the case of a 60-years-old man who complained fever and left knee pain. Fever and arthralgia appear once a month, and these symptoms disappear spontaneously in 3 days. The patient came to our hospital to receive Kampo treatment, because the patient experienced improving these symptoms by Kampo medicine about 20 years ago. I judged the arthralgia as kanshippi, because the arthralgia improved when the patient warmed the joint. We prescribed keishikajutsubuto 7.5 g/day. Arthralgia improved after administration of keishikajutsubuto, but the attack appeared every month. We prescribed maobushisaishinto 5 g/day in addition to keishikajutsubuto 5 g/day for further improvement of arthralgia. The frequency of fever and arthralgia attack was dramatically decreased after we prescribed keishikajutsubuto 5 g/day and maobushisaishinto 5 g/day. We considered the possibility of palindromic rheumatism based on clinical symptoms, X-ray in other clinic and blood test results in our hospital. We report an effective case of keishikajutsubuto and maobushisaishinto on arthritis attacks with fever that resolved spontaneously in a short time.
