ABSTRACT

ABSTRACT Cancer cases and survival have increased significantly in recent decades. Objective: In this study, we sought to evidence whether bone, joint and cartilage neoplasms are increasing with the aging of the Brazilian population, using the analysis of the DATASUS and IBGE databases, between 1979 and 2020. Methods: We compared the means and the proportion of death in Brazil, to observe the confidence interval overlaps, separated by region. Comparison between genders, age group, death and specific rate were compared via proportion tests and the trend was investigated via time series analysis. Results: Through the analyses, we can see that there is an increasing trend of cases, about 2.5 times in the period. Separated by region, the Southeast stands out, with a number of deaths about 6 times higher than other regions. Conclusion: Metastatic carcinoma is the most common neoplasm treated by orthopedic surgeons, and it is essential to adapt to this future projection, with cases of pathological bone involvement resulting from metastatic carcinomas, increasingly present in the routine of orthopedic surgeons. Level of Evidence IV, Cross-Sectional Observational Study.


RESUMO Os casos oncológicos e a sobrevida aumentaram expressivamente nas últimas décadas. Objetivo: Investigar se as neoplasias de osso, articulação e cartilagem estão aumentando com o envelhecimento da população brasileira, por meio da análise das bases de dado do Sistema Único de Saúde (DATASUS) e do Instituto Brasileiro de Geografia e Estatística (IBGE), entre os anos de 1979 e 2020. Métodos: Realizamos a comparação de médias e de proporção de morte entre as regiões do Brasil para observar as sobreposições de intervalo de confiança em cada região. A comparação entre sexo, faixa etária, óbito e taxa específica foi feita via testes de proporção, e a tendência foi investigada via análise de séries temporais. Resultados: Foi evidenciada uma tendência crescente dos casos de neoplasia, com um aumento de cerca de 2,5 vezes no período analisado. Entre as regiões do Brasil, destacou-se o Sudeste, com número de mortes cerca de seis vezes maior que outras regiões. Conclusão: O carcinoma metastático é a neoplasia mais comum tratada pelos cirurgiões ortopédicos, e é fundamental nos adequarmos a essa projeção futura, com casos de comprometimento ósseo patológicos decorrentes de carcinomas metastáticos cada vez mais presentes na rotina do cirurgião ortopédico. Nível de Evidência IV, Estudo Observacional Transversal.

ABSTRACT

Abstract Relapsing polychondritis is a rare multisystem disease involving cartilaginous and proteoglycan-rich structures. The diagnosis of this disease is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations. The spectrum of clinical presentations may vary from intermittent episodes of painful and often disfiguring auricular and nasal chondritis to an occasional organ or even life-threatening manifestations such as lower airway collapse. There is a lack of awareness about this disease is mainly due to its rarity. In 2020, VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, a novel autoinflammatory syndrome, was described. VEXAS syndrome is attributed to somatic mutations in methionine-41 of UBA1, the major E1 enzyme that initiates ubiquitylation. This new disease entity connects seemingly unrelated conditions: systemic inflammatory syndromes (relapsing chondritis, Sweet's syndrome, and neutrophilic dermatosis) and hematologic disorders (myelodysplastic syndrome or multiple myeloma). Therefore, this article reviews the current literature on both disease entities.

ABSTRACT

ABSTRACT Biliary atresia (BA) is a fibro-obliterative cholestatic disease of infancy. The presence of cartilage in the resected tissue is an uncommon finding. We documented the presence of both mature and immature hyaline cartilage in the portal plate and the wall of the gallbladder in a 2-month-old girl infant with BA who had undergone Kasai portoenterostomy. The presence of cartilage could be part of a heterotopia or an uncommon connective tissue metaplasia. The presence of immature cartilage with the merging of the perichondrium with the soft tissue highlights a metaplastic etiology in the index case.

ABSTRACT

Introducción: el cierre de las perforaciones timpánicas se realiza con diferentes materiales, entre ellos el cartílago y el pericondrio. En este estudio se compararon los resultados anatómicos y funcionales obtenidos con ambos materiales, y se evaluaron posibles factores asociados con los buenos resultados. Material y métodos: estudio retrospectivo en pacientes intervenidos de timpanoplastia sin mastoidectomía entre el 1 de enero de 2001 y el 31 de diciembre de 2018. Resultados: se incluyeron 544 timpanoplastias. En la mayoría se utilizó cartílago (78,5 %) y en el resto pericondrio. El cartílago se utilizó con mayor frecuencia en los menores de 18 años (p=0,001), perforaciones totales y subtotales (p=0,000) y timpanoplastias secundarias y terciarias (p=0,008). No hubo diferencias en el tiempo de seguimiento (15,68 ± 22,18 meses frente al 12,86 ± 14,9 meses, p=0,169). La tasa de éxito anatómico fue mayor en el grupo de cartílago, sin diferencias en los resultados auditivos (82 % con cartílago y 78,3 % con pericondrio). El éxito anatómico se relacionó con la técnica utilizada para la reconstrucción con cartílago, mientras que los resultados auditivos se asociaron significativamente con el estado de la mucosa del oído medio y la cadena de huesecillos en el momento de la cirugía y el éxito anatómico posquirúrgico. Conclusiones: con el cartílago se consiguieron mejores resultados anatómicos que con el pericondrio, sin diferencias a nivel funcional. Sin embargo, los resultados funcionales empeoraron si había patología a nivel del oído medio y en ausencia de restauración anatómica.


Introduction: Different materials are used to close tympanic perforations. This stu-dy aimed to compare anatomical results obtained with cartilage and perichondrium and evaluate factors associated with successful results. Material and method: Re-trospective study of patients who underwent tympanoplasty without mastoidectomy between January 1, 2001, and December 31, 2018. Demographic data, ear pathology, surgical intervention, and anatomical and functional results were collected. Results:544 tympanoplasty were included. Cartilage was the most used (78.5%). Cartilage was used more frequently in children under 18 years (p = 0.001), to reconstruct total and subtotal perforations (p = 0.000) and in secondary and tertiary tympanoplasty (p = 0.008). Follow-up time did not differ between the two groups (15.68 ± 22.18 months vs. 12.86 ± 14.9 months, p = 0.169). The anatomical success rate was higher in the cartilage group, with no significant differences in hearing outcomes (82% with cartilage and 78.3% with perichondrium). Anatomical success was related to the technique used for cartilage reconstruction (monoblock or palisade). Hearing re-sults were significantly associated with the state of middle ear mucosa at the time of surgery, the state and mobility of the ossicle chain, and post-surgical anatomical suc-cess. Conclusions: Cartilage achieved better anatomical results than perichondrium. Both materials were comparable on a functional level. However, the functional re-sults worsen if there is pathology of the middle ear (mucosa or chain of ossicles) and anatomical restoration is not achieved.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery.@*METHODS@#The clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation.@*RESULTS@#All patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones ( P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied.@*CONCLUSION@#Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.

ABSTRACT

Introdução: A síndrome de Binder também pode ser conhecida como displasia maxilonasal e é uma malformação congênita caracterizada por hipoplasia nasomaxilar devido a um subdesenvolvimento do esqueleto facial médio. A atual incidência ou prevalência ainda é desconhecida, mas afeta aproximadamente um recém-nascido vivo em cada 10.000 nascimentos. O diagnóstico pode ser clínico ou associado a ultrassonografia pré-natal, caracterizada por nariz achatado e convexidade anormal da maxila. O tratamento é cirúrgico para correção das anormalidades estéticas e funcionais. Relato de Caso: Paciente que recebeu diagnóstico de síndrome de Binder aos 14 anos, sem outras malformações associadas, com queixa estética e funcional nasal. A correção cirúrgica foi iniciada pela extração de um bloco da sexta cartilagem costal à esquerda, com abertura nasal na margem columelar, no padrão de uma rinoplastia aberta, e dissecados os tecidos no plano subSMAS. Após preparo da área receptora nasal, foram esculpidos bloco de cartilagem para reconstrução do dorso nasal, enxertos alares e enxerto de cartilagem septal. Houve melhora de projeção da ponta nasal e alongamento nasal. Conclusão: A rinoplastia pode ser uma cirurgia desafiadora nesses pacientes, sendo a reconstrução autóloga com o uso de cartilagem costal indicada pela literatura como a melhor opção. É necessário individualizar cada caso para programação de enxertos e reestruturação nasal, sendo fundamental também a melhora funcional desses casos.


Introduction: Binder's syndrome can also be known as maxillonasal dysplasia and it is a congenital malformation characterized by nasomaxillary hypoplasia resulting from an underdevelopment of the middle facial skeleton. The current incidence or prevalence is still unknown, but it affects approximately one child in every 10,000 births. The diagnosis can be clinical or associated with prenatal ultrasonography, characterized by a flattened nose and abnormal maxillary convexity. The treatment is surgical to correct aesthetic and functional abnormalities. Case Report: Patient diagnosed with Binder's syndrome at the age of 14, without other associated malformations, with aesthetic and functional nasal complaints. Surgical correction began with the extraction of a block of the sixth costal cartilage on the left, with a nasal opening on the columellar margin, in the pattern of an open rhinoplasty, and tissue dissection in the sub-SMAS plane. After preparing the nasal receptor area, a block of cartilage was sculpted for reconstruction of the nasal dorsum, alar grafts and septal cartilage grafts. There was an improvement in the projection of the nasal tip and nasal dorsum. Conclusion: Rhinoplasty can be a challenging surgery in these patients, and the literature indicates that the best option is autologous reconstruction with costal cartilage. It is necessary to individualize each case to schedule nasal grafts and restructuring, and functional improvement in these cases is also essential

ABSTRACT

Abstract Articular cartilage injuries are common and lead to early joint deterioration and osteoarthritis. Articular cartilage repair techniques aim at forming a cartilaginous neo-tissue to support the articular load and prevent progressive degeneration. Several techniques are available for this purpose, such as microfracture and chondrocyte transplantation. However, the procedural outcome is often fibrocartilage, which does not have the same mechanical resistance as cartilaginous tissue. Procedures with autologous osteochondral graft have a morbidity risk, and tissue availability limits their use. As such, larger lesions undergo osteochondral transplantation using fresh or frozen grafts. New techniques using minced or particulate cartilage fragments or mesenchymal stem cells are promising. This paper aims to update the procedures for treating chondral lesions of the knee.


Resumo As lesões da cartilagem articular são comuns e levam à deterioração precoce da articulação e ao desenvolvimento da osteoartrite. As técnicas de reparo da cartilagem articular visam a formação de um neo-tecido cartilaginoso capaz de suportar carga articular e evitar a progressão da degeneração. Há várias técnicas disponíveis para esse fim, como a microfratura e o transplante de condrócitos. Entretanto muitas vezes o desfecho do procedimento é a formação de fibrocartilagem, que não possui a mesma resistência mecânica do tecido cartilaginoso. Em outros procedimentos, nos quais é realizado enxerto osteocondral autólogo, há risco de morbidade associada ao procedimento, além da disponibilidade limitada de tecido. Por esse motivo, o transplante osteocondral, utilizando enxertos a fresco ou congelados tem sido utilizado para lesões de maior volume. Por fim, novas técnicas utilizando fragmentos de cartilagem picada ou particulada, assim como o uso de células tronco mesenquimais se apresentam como promissores. O objetivo desse artigo é realizar uma atualização dos procedimentos para tratamento das lesões condrais do joelho.

ABSTRACT

SUMMARY: Refixation of the damaged acetabular labrum is a method of surgical treatment of the hip joint that can promote the repair of joint function after injury and prevent premature osteoarthritis. We sought to determine the condition of the hip joint in rabbits 4 months after excision of the acetabular labrum and the condition of the joint after labral refixation. The articular cartilage of the femoral head and acetabulum was examined by histological methods, multipoint measurement of cartilage thickness, and the ratio between cartilage matrix and chondrocytes lacunae, and the condition of cartilage according to the OARSI grading scale was carried out. On this model, a correlation analysis was performed between the results of the OARSI grading scale and the data of linear morphometry. All these parameters made it possible to better assess changes in articular cartilage. The ratio between matrix and chondrocyte lacunae turned out to be a method that allows establishing early cartilage damage when erosion, fibrosis or deformation did not occur. We found significant differences between the condition of the cartilage after exicion of acetabular labrum and after labral refixation, which give hope to confirm that this surgical technique can delay or prevent progressive changes in the cartilage of the damaged hip joint.


La refijación del labrum acetabular dañado es un método de tratamiento quirúrgico de la articulación coxal, que puede promover la reparación de la función articular después de una lesión y prevenir la osteoartritis prematura. Intentamos determinar el estado de la articulación coxal en conejos de 4 meses después de la escisión del labrum acetabular y observar el estado de la articulación después de la refijación del labrum. El cartílago articular de la cabeza femoral y el acetábulo se examinó por métodos histológicos, se midió a través de multipunto el grosor del cartílago y se realizó la relación entre la matriz del cartílago y las lagunas de condrocitos, y se llevó a cabo la condición del cartílago según la escala de clasificación OARSI. Sobre este modelo se realizó un análisis de correlación entre los resultados de la escala de calificación OARSI y los datos de la morfometría lineal. Todos estos parámetros permitieron evaluar mejor los cambios en el cartílago articular. La relación entre la matriz y las lagunas de condrocitos resultó ser un método que permite establecer temprano el daño del cartílago cuando no se presentó erosión, fibrosis o deformación. Encontramos diferencias significativas entre la condición del cartílago después de la extirpación del labrum acetabular y después de la refijación del labrum, lo que da la esperanza de confirmar que esta técnica quirúrgica puede retrasar o prevenir cambios progresivos en el cartílago de la articulación coxal dañada.

ABSTRACT

Abstract Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment. In the upper limbs, this is very evident in the systematization of the reduction and percutaneous fixation of supracondylar fractures of the humerus and fractures of the forearm bones. In the lower limbs, the same occurs with diaphyseal fractures of the femur and tibia. However, there are gaps in the literature. The available published studies show low scientific evidence. Thus, it can be inferred that, even though the surgical approach is more present, the treatment of pediatric fractures should always be individualized and conducted according to the knowledge and experience of the professional physician, taking into account the presence of technological resources available for the care of the small patient. All possibilities, non-surgical and/or surgical, should be included, always instituting actions based on science and in agreement with the family's wishes.


Resumo Historicamente, as cirurgias no esqueleto imaturo eram reservadas às fraturas expostas ou articulares. Nos últimos anos, a melhora na qualidade e segurança das anestesias, novos equipamentos de imagem, implantes desenhados especialmente para fraturas pediátricas, associados à possibilidade de menor tempo de hospitalização e rápido retorno ao convívio social vêm demonstrando uma nova tendência de avaliar e tratar fraturas na criança. O objetivo deste artigo de atualização é responder às seguintes questões: (1) estamos realmente ficando mais cirúrgicos na abordagem das fraturas em crianças? (2) Caso isto seja verdadeiro, esta conduta cirúrgica está baseada em evidências científicas? De fato, nas últimas décadas, a literatura médica demonstra artigos que suportam melhor evolução das fraturas na criança com o tratamento cirúrgico. Nos membros superiores, isto fica muito evidente na sistematização da redução e fixação percutânea das fraturas supracondilianas do úmero e das fraturas de ossos do antebraço. Nos membros inferiores, o mesmo ocorre com fraturas diafisárias do fêmur e tíbia. No entanto, há lacunas na literatura. Os estudos publicados são geralmente com baixa evidência científica. Assim, pode-se deduzir que, mesmo sendo a abordagem cirúrgica mais presente, o tratamento de fraturas pediátricas deve ser sempre individualizado e conduzido de acordo com o conhecimento e experiência do médico profissional, levando em conta a presença de recursos tecnológicos disponíveis para o atendimento do pequeno paciente. Deve-se incluir todas as possibilidades, não cirúrgicas e/ou cirúrgicas, sempre instituindo ações baseadas na ciência e em concordância com os anseios da família.

ABSTRACT

Background: Airway formation is one of the earliest events in development of respiratory system. However, maturation of airway continues well in post-natal life. The trachea has framework of incomplete ring of hyaline cartilage united by fibrous tissue and smooth muscle through which air conduction takes place. The trachea-bronchial mucosa is target for host of airborne toxic agents; bacterial and viral agents, allergens, reactive gases, aerosols, and irritant particles. This fascinates many workers for detailed study of epithelium or lining air passage. Aims and Objectives: The present study was undertaken to document normal developmental microscopic structure of tracheal cartilage in fetuses of different age group (gestational ages between 12th and 40th weeks) and to compare the difference between different age groups. Materials and Methods: Tissues from trachea of various age group fetuses were collected, processed, and stained with H and E and Masson’s trichrome. Results: Development of tracheal cartilage was observed into three trimesters. The 2nd and 3rd trimesters were further divided in the early 2nd (13th–16th weeks), mid-2nd (17th–20th weeks), late 2nd (21st–24th weeks), early 3rd (25th–28th weeks), mid-3rd (29th–32nd weeks), and late 3rd (33rd–40th weeks) phases. Conclusion: Perichondrium of cartilage had shown well-marked outer fibrous layer with increased vascularity by late 2nd to early 3rd trimester. Well-marked inner cellular layer of perichondrium was noticed by 3rd trimester, while cartilage had shown active chondrocytes by late 2nd to early 3rd trimester. At the late 3rd trimester, typical hyaline cartilage had shown chondrocytes in cell nest surrounded by territorial matrix.

ABSTRACT

OBJECTIVE@#To provide an overview of the incidence of knee donor -site morbidity after autologous osteochondral mosaicplasty.@*METHODS@#A comprehensive search was conducted in PubMed, EMbase, Wanfang Medical Network, and CNKI databases from January 2010 to April 20, 2021. Relevant literature was selected based on predefined inclusion and exclusion criteria, and data were evaluated and extracted. The correlation between the number and size of transplanted osteochondral columns and donor-site morbidity was analyzed.@*RESULTS@#A total of 13 literatures were included, comprising a total of 661 patients. Statistical analysis revealed an incidence of knee donor-site morbidity at 8.6% (57/661), with knee pain being the most common complaint, accounting for 4.2%(28/661). There was no significant correlation between the number of osteochondral columns and postoperative donor-site incidence (P=0.424, N=10), nor between the diameter size of osteochondral columns and postoperative donor-site incidence(P=0.699, N=7).@*CONCLUSION@#Autologous osteochondral mosaicplasty is associated with a considerable incidence of knee donor-site morbidity, with knee pain being the most frequent complaint. There is no apparent correlation between donor-site incidence and the number and size of transplanted osteochondral columns. Donors should be informed about the potential risks.

ABSTRACT

OBJECTIVE@#To investigate the effectiveness of anterior cruciate ligament (ACL) reconstruction assisted by personalized femoral locator based on the apex of deep cartilage (ADC) combined with patient imaging data.@*METHODS@#Between January 2021 and January 2022, a total of 40 patients with primary ACL rupture were selected and randomly divided into study group (ACL reconstruction assisted by personalized femoral locator based on ADC) and control group (ACL reconstruction assisted by intraoperative fluoroscopy and traditional femoral locator), with 20 cases in each group. There was no significant difference in gender, age, body mass index, affected side, cause of injury, and preoperative International Knee Documentation Committee (IKDC) score, Lyshlom score, and Tegner score between the two groups ( P>0.05). IKDC score, Lyshlom score, and Tegner score were used to evaluate the functional recovery of the affected knee before operation and at 3, 6, and 12 months after operation. CT scan and three-dimensional reconstruction were performed before and after operation to measure the horizontal distance from ADC to the anterior cartilage margin (L) and the horizontal distance from ADC to the center of the femoral canal (I), and the anteroposterior position of the bone canal (R) was calculated by I/L; the distance from the center to the distal cartilage margin (D) was measured on the two-dimensional cross section; the R value and D value were compared between the two groups.@*RESULTS@#The operation time of the study group was significantly less than that of the control group [ MD=-6.90 (-8.78, -5.03), P<0.001]. The incisions of the two groups healed by first intention, and no complication such as intra-articular infection, nerve injury, and deep vein thrombosis of lower limbs occurred. There was no significant difference in the R value and D value between the preoperative simulated positioning and the actual intraoperative positioning in the study group [ MD=0.52 (-2.85, 3.88), P=0.758; MD=0.36 (-0.39, 1.11), P=0.351]. There was no significant difference in the actual intraoperative positioning R value and D value between the study group and the control group [ MD=1.01 (-2.57, 4.58), P=0.573; MD=0.24 (-0.34, 0.82), P=0.411]. The patients in both groups were followed up 12-13 months (mean, 12.4 months). The IKDC score, Lysholm score, and Tegner score of the two groups increased gradually with time, and there were significant differences between pre- and post-operation ( P<0.05). There was no significant difference in the scores between the two groups at each time point after operation ( P>0.05).@*CONCLUSION@#The personalized femoral locator based on ADC can accurately assist the femoral tunnel positioning in ACL reconstruction, which can shorten the operation time when compared with traditional surgical methods, and achieve satisfactory early effectiveness.

ABSTRACT

OBJECTIVE@#To investigate the effect of electroacupuncture on osteoarthritis in rats and explore the possible mechanism.@*METHODS@#Thirty SD rats were randomly divided into osteoarthritis model group, electro-acupuncture group and control group (n=10), and in the former two groups, early osteoarthritis was induced using a modified DMM surgical modeling method. After successful modeling, the rats in the electro-acupuncture group were treated with electro-acupuncture at bilateral "Housanli" and "Anterior knee point". Behavioral tests of the rats were performed and scored using the LequesneMG scale. Subchondral bone degeneration was observed in each group, and serum levels of IL-1β, ADAMTS-7, MMP-3 and COMP were measured using ELISA. The mRNA and protein expressions of IL-1β, Wnt-7B, β-catenin, ADAMTS-7, and MMP-3 in the cartilage tissue of the knee joints were detected using RT-PCR and Western blotting.@*RESULTS@#In behavioral tests, the rats in the model and electroacupuncture groups had significantly higher LequesneMG scores after modeling than those in the control group (P < 0.05). After 20 days of treatment, LequesneMG scores were significantly lowered in rats in the electroacupuncture as compared with the model rats (P < 0.05). Imaging examination revealed obvious subchondral bone damage in both the electroacupuncture group and the model group, but the damages were significantly milder with former group. Compared with the model rats, the rats receiving electroacupuncture had significantly lower serum levels of IL-1β, ADAMTS-7, MMP-3 and COMP (P < 0.05) with also lower expressions of IL-1β, Wnt-7B, β-catenin, ADAMTS-7 and MMP-3 in the cartilage tissues at both the mRNA and protein levels (P < 0.05).@*CONCLUSION@#Electroacupuncture can alleviate joint pain and improve subchondral bone damage in rats with osteoarthritis by reducing IL-1β levels in the joint cartilage tissue and serum to alleviate joint inflammation and by reducing such cytokines as ADAMTS-7 and MMP-3 via regulating the Wnt-7B/β-catenin signaling pathway.

ABSTRACT

Rheumatoid arthritis (RA) is a systemic chronic auto-inflammatory disease, characterized by infiltration of inflammatory cells, pannus formation, articular cartilage destruction, and bone matrix destruction. Therefore, improving articular cartilage destruction has an important impact on the treatment of RA. Chinese medicine has a good application effect in improving cartilage destruction of RA due to its characteristics of multiple components, multiple targets, high activity and low side effects. Based on this, the author reviewed relevant literature to summarize the relevant research and mechanism of Chinese medicine and its active components in improving RA cartilage destruction. The results showed that Chinese medicine and its active components can improve RA cartilage destruction by regulating inflammatory factors, phosphatidylinositol 3-kinase/protein kinase B, Wnt/β- catenin, nuclear factor-κB, mitogen-activated protein kinase, Janus kinase 2/signal transduction and activator of transcription 3/ vascular endothelial growth factor, microRNAs, fibroblastic synovial cells.

ABSTRACT

Objective:To observe the effects of different moxibustion time on cartilage morphology,tumor necrosis factor(TNF)-α and interleukin(IL)-10 of the knee joint in rats with knee osteoarthritis(KOA),and to explore the best treatment time of moxibustion for KOA.Methods:Healthy male Wistar rats were randomly divided into a blank group,a model group,a 15-minute-moxibustion group,a 30-minute-moxibustion group,and a 60-minute-moxibustion group,with 10 rats in each group.Except for the blank group,the KOA model was established in all groups by injecting sodium iodoacetate solution into the knee joint cavity of rats.Rats in the 15-minute-moxibustion group,the 30-minute-moxibustion group,and the 60-minute-moxibustion group were all treated with mild moxibustion intervention for 15 min,30 min,and 60 min,respectively at Neixiyan(EX-LE4)and Dubi(ST35)points near the patella,3 times a week for 4 weeks,12 times in total.Rats in the blank group and the model group were fixed for 30 min without moxibustion intervention.Macroscopic observation for the smoothness of knee cartilage surface was performed after the intervention.Hematoxylin-eosin staining,toluidine blue staining,and Mankin score were used to evaluate the pathological changes in the cartilage.The expression levels of TNF-α and IL-10 in the serum were detected by enzyme-linked immunosorbent assay.Results:Compared with the blank group,the articular cartilage surface in the model group was rough,the chondrocyte arrangement was irregular,the Mankin score and the serum TNF-α expression were significantly increased(P<0.05),while the expression of serum IL-10 was significantly decreased(P<0.05).Compared with the model group,the articular cartilage surface was smoother,the chondrocytes were arranged neatly,the Mankin score and serum TNF-α expression level were significantly lower in the three moxibustion intervention groups(P<0.05);the serum IL-10 level in the 30-minute-moxibustion group and the 60-minute-moxibustion group was increased significantly(P<0.05).Compared with the 15-minute-moxibustion group,the articular cartilage surface in the 30-minute-moxibustion group and the 60-minute-moxibustion group was smoother,the chondrocyte arrangement was more regular,the Mankin score and the serum TNF-α level were decreased significantly(P<0.05),and the serum IL-10 level was increased(P<0.05).There was no significant difference in the serum TNF-α or IL-10 level between the 30-minute-moxibustion group and the 60-minute-moxibustion group(P>0.05).Conclusion:Moxibustion can obviously improve the morphology and structure of KOA articular cartilage,protect articular cartilage,inhibit cartilage inflammation,and delay KOA cartilage degeneration.Moxibustion's effect is closely related to moxibustion time;the therapeutic effect of the 30-minute-moxibustion and the 60-minute-moxibustion is better than that of the 15-minute-moxibustion.

ABSTRACT

Objective:To explore the application of expanded polytetrafluoroethylene (ePTFE) as the main support combined with a small amount of ear cartilage in rhinoplasty.Methods:Through a nasal opening approach, the ePTFE was used as a support implant for the nasal dorsum and columella, and unilateral concha cartilage was used as a nasal tip modification graft.Results:This method was applied in 56 cases of rhinoplasty (36 cases of initial nose, 20 cases of silicone augmentation rhinoplasty). The wounds of 55 patients healed at one stage without complications, with satisfactory results (average follow-up of 6 months). In one case, nasal mucosa was damaged early after surgery, and the ePTFE was partially exposed, which healed after debridement and suture.Conclusions:For most primary rhinoplasty and simple repair of the nose, using ePTFE as the main support combined with a small amount of ear cartilage, has the advantages of fewer materials, rapid surgery, mild trauma, and stable postoperative results.

ABSTRACT

Objective:To investigate the effect of autologous costal cartilage cortex as nasal tip support and modified graft for nasal tip contour improvement.Methods:From June 2020 to June 2021, 116 patients (male 26, female 90, aged 20-45 years) who received rhinoplasty in the cosmetic surgery department of Myoung Beaucare Clinic of Beijing, were examined the costal cartilage by CT, and the costal cartilage was cut. The costal cartilage cortex was made into " strip" and " cap" grafts to shape the nasal tip, and the nasal dorsum was raised by polytetrafluoroethylene or silicone prosthesis for comprehensive rhinoplasty.Results:A total of 116 patients were followed up for an average of 11.7 months. After the operation, there was no space occupying in the nasal cavity, no graft protrusion, no obvious foreign body feeling in the nasal valve, and the nasal tip could swing left and right. At the same time, the nasal tip showed obvious signs, the lower lobule was full, and there were no complications such as cartilage appearance, exposure, infection, etc. Due to the untreated deviation of nasal septum, 3 cases had deviation of nasal columella and asymmetric nostrils. The shape of nasal tip was stable in the remaining 113 cases, and satisfactory results were obtained.Conclusions:By using autologous costal cartilage cortex as nasal tip support and modification graft for nasal tip contour improvement, the shaped nasal tip is soft and movable, and does not affect the airway. It is a good surgical technique in nasal tip plastic surgery, which is worthy of clinical application.

ABSTRACT

Objective:To explore the application of nasal aesthetic polygon theory in the reconstruction of new domes on nasal tip with autogenous costal cartilage.Methods:From June 2019 to June 2021, 116 patients (26 males and 90 females) received rhinoplasty, CT-assisted examination of the costal cartilage, nasal bone and nasal cartilage was performed, and the autogenous costal cartilaginous cortex was used to make dome reconstruction grafts that were transplanted to the original alar cartilage and partially fixed to the original nasal septum cartilage to form a satisfactory and natural nasal shape.Results:All the patients were followed up for 6-24 months. No cartilaginous, overrotated or underrotated appearance was found in nasal tip. The shape of nasal tip was clear and good, with an obvious performance point and full lower lobule. The nose was tall and straight, and looked natural and beautiful in three dimensions.Conclusions:The nasal aesthetic polygon theory is used to guide the reconstruction of new domes with autogenous costal cartilage in nasal tip surgery. Compared to the cap and shield grafts, the nasal tip is more close to the normal anatomical structure, the shape and texture are more similiar to the natural state and the nasal tip is softer by using autogenous costal cartilage, and so it is an ideal surgical procedure for nasal tip reconstruction.

ABSTRACT

Objective:To investigate the postoperative effect of paranasal concavity augment by block united with diced autologous costal cartilage.Methods:The data of 76 patients who were underwent costal cartilage rhinoplasty together with paranasal augmentation from January 2016 to December 2019 were analyzed retrospectively. The surgical technique was described in detail. Medical charts and operative records were reviewed to summary the complications. Patients′subjective satisfaction of the postoperative nasal appearance was self-evaluated with grading (1 worse, 2 no change, 3 improved, and 4 much improved). Cosmetic effects were evaluated by the measurements of the nasolabial angle and the distance between ACJ and intertragic notch preoperatively and postoperatively.Results:The postoperative follow-up duration was 6 to 34 months. Overall, functional and aesthetic outcome was satisfactory in most patients, and the mean score by the patients′self-evaluation was 3.4±0.5. Graft exposure, mobility, or significant resorption, pneumothorax or significant donor-site pain were not observed. The average nasolabial angle was changed from (78.2±13.2)° preoperatively to (89.8±10.2)° 6 months postoperative at the last follow-up ( t=152.00, P<0.01). And the distance from the alar-cheek junction to the left tragus was increased by 3.8±2.1 (2.2-6.1) mm. Conclusions:Costal cartilage rhinoplasty combined with augmentation of parasal area can improve parasal depression, with stable postoperative effect and fewer postoperative complications, and has a good effect for patients with normal occlusal relationship or mild abnormality.
