O uso da proteína botulínica na correção do sorriso gengival / The use of botulinum protein in the correction of gingival smile

A sociedade está cada vez mais exigente e em busca de excelência quando o assunto é estética facial. O sorriso tem grande impacto na harmonia da face e, atualmente, os pacientes estão mais conscientes sobre a influência da gengiva na beleza do sorriso. A exposição da gengiva em excesso, conhecida como sorriso gengival, afeta a estética, podendo interferir na autoestima e nas relações sociais dos pacientes. Existem diversos procedimentos descritos para solucionar o problema e, para o planejamento do caso e escolha do método, é preciso determinar a etiologia e levar em consideração o desejo do paciente. A injeção da proteína botulínica é uma alternativa minimamente invasiva que está sedo cada vez mais utilizada para a correção do sorriso gengival. Com isso, o objetivo do presente trabalho monográfico foi realizar uma revisão de literatura sobre o uso da toxina botulínica na correção do sorriso gengival, analisando técnicas de injeção, identificando o efeito imediato e a longo prazo da toxina nos músculos elevadores do lábio superior, além de avaliar a relevância desse método na correção do sorriso gengival, sozinho ou em conjunto com outros procedimentos. Foi realizada uma revisão de literatura nas bases de dados PubMed e Scielo, buscando artigos dos anos de 2013 até 2022, utilizando os descritores "botulinum toxin", "botox", "gummy smile", "gingival display" e "gingival exposure". Essa revisão analisa 15 artigos que discorrem sobre o método, durabilidade e eficácia da aplicação de proteína botulínica para correção do sorriso gengival. Algumas variantes diferenciam as técnicas de aplicação, como a marca do produto e recomendações do fabricante, classificação do sorriso e extensão da exposição gengival. Com base na revisão de literatura, pôde-se concluir que, apesar de ser transitório, esse procedimento se mostrou eficaz, tanto ao ser realizado como método principal, quanto como coadjuvante no tratamento. Além de ser comprovadamente seguro, rápido, minimamente invasivo e ser o tratamento de preferência entre os pacientes, com alto índice de satisfação, são raras as complicações relacionadas a aplicação da proteína botulínica para esse fim.

Society is becoming increasingly demanding, seeking excellence in facial aesthetics. The smile greatly impacts facial harmony, and nowadays, patients are more aware of the influence of the gums on smile beauty. Excessive gum exposure, known as gummy smile, affects aesthetics and can interfere with patients' self-esteem and social relationships. There are various procedures described to address this issue, and for case planning and method selection, it is necessary to determine the etiology and take into account the patient's desires. The injection of botulinum protein is a minimally invasive alternative that is increasingly being used for gummy smile correction. Thus, the aim of this monographic work was to conduct a literature review on the use of botulinum toxin in gummy smile correction, analyzing injection techniques, identifying the immediate and long-term effects of the toxin on the upper lip elevator muscles, and evaluating the relevance of this method in gummy smile correction, either alone or in conjunction with other procedures. A literature review was conducted in the PubMed and Scielo databases, seeking articles from 2013 to 2022, using the descriptors "botulinum toxin", "botox", "gummy smile", "gingival display", and "gingival exposure". This review analyzes 15 articles that discuss the method, durability, and effectiveness of botulinum toxin application for gummy smile correction. Some variations differentiate the application techniques, such as the product brand and manufacturer's recommendations, smile classification, and extent of gum exposure. Based on the literature review, it was possible to conclude that, despite being temporary, this procedure proved to be effective, both when performed as the main method and as an adjunct in treatment. In addition to being proven safe, fast, minimally invasive, and the preferred treatment among patients, with a high satisfaction rate, complications related to botulinum toxin application for this purpose are rare.

Oromandibular dystonia as a cause of temporomandibular disorder (Case report) / Distonia oromandibular como causa de disfunção temporomandibular (Relato de caso)

Temporomandibular disorders (TMD) can have multiple etiologies, including oromandibular dystonia (OMD). However, in a few cases, the OMD can evolve from cervical dystonia (CD), leading to severe bone degeneration. The purpose of this case report of a 64-year-old woman presenting to the Outpatient Neurology Clinic of the Federal University of Bahia is to illustrate the development of oromandibular dystonia with temporomandibular joint (TMJ) dysfunction after 10 years of cervical dystonia. Clinical examination showed bone degeneration of the mandibular ramus and right TMJ click, a prevalent sound in patients with temporomandibular disorders when they open their mouths or chew. After onabotulinum toxin type A injections in the right lateral pterygoid muscle, the patient improved in swallowing and pain. This case highlights the importance of close follow-up of cervical dystonia patients to identify new dystonic muscles. In our patient, lateral pterygoid muscle involvement was followed by several comorbidities, such as dysphagia and jawbone abnormalities.

Os distúrbios temporomandibulares (DTM) podem ter múltiplas etiologias, incluindo a distonia oromandibular (DO). No entanto, em raros casos, a DO pode evoluir a partir da distonia cervical (DC) e raramente pode levar a degeneração óssea. O objetivo deste relato de caso de uma mulher de 64 anos atendida no Ambulatório de Neurologia da universidade Federal da Bahia é ilustrar o desenvolvimento de distonia oromandibular com disfunção da articulação temporomandibular (ATM) após 10 anos de distonia cervical. O exame clínico mostrou degeneração óssea do ramo mandibular e clique na ATM direita, um som prevalente em pacientes com distúrbios temporomandibulares quando abrem a boca ou mastigam. Após injeções de toxina botulínica tipo A no músculo pterigoideo lateral direito, a paciente apresentou melhora na deglutição e na dor. Este caso destaca a importância do acompanhamento próximo de pacientes com distonia cervical para identificar novos músculos distônicos. Em nossa paciente, o envolvimento do músculo pterigoide lateral foi seguido por várias comorbidades, como disfagia e anormalidades ósseas da mandíbula.

Exploration on Scientific Connotation of Pathogenesis Theory of Gastric Cancer"Spleen Deficiency and Stasis Toxin"Based on the Reprogramming of Glucose Metabolism in Tumor-associated Macrophages / 中国中医药信息杂志

The pathogenesis theory of"spleen deficiency and stasis toxin"in gastric cancer holds that spleen is the source of generation and transformation of qi and blood,that spleen deficiency is the internal basis of disease and throughout the disease.Stasis toxin is based on spleen deficiency,which is the fundamental pathogenesis of gastric cancer.In the pathological process of gastric cancer,a variety of metabolic substances in tumor cells and tumor microenvironment,mainly glucose metabolic reprogramming,undergo metabolic changes to reconstruct the phenotype and function of tumor-related macrophages,which is consistent with the pathogenesis theory of"spleen deficiency and stasis toxin".Therefore,this article focused on the reprogramming of glucose metabolism in tumor microenvironment to drive the phenotypic remodeling of tumor-related macrophages,explored the scientific connotation of the pathogenesis theory of"spleen deficiency and stasis toxin"of gastric cancer,and provided references for the theoretical and clinical research on the treatment of gastric cancer by TCM.

Syndrome Differentiation and Treatment of Thyroid Carcinoma Based on the Theory of Cancer Toxin Pathogenesis / 中国中医药信息杂志

On the basis of inheriting the cancer toxin theory of Zhou Zhongying,a national TCM master,Professor Cheng Haibo's team proposes the theory of cancer toxin pathogenesis.This theory believes that thyroid carcinoma is caused by pathogenic surroundings,emotional injury,irregular diet and other factors,which cause the accumulation of qi stagnation,phlegm coagulation,blood stasis and cancer toxin in the neck.The main pathological factors of thyroid carcinoma are"qi,phlegm,stasis and toxin".The disease is located in front of the neck and is greatly related to liver,spleen and kidney."Liver-qi stagnation,phlegm and stasis containing toxin"is its core pathogenesis.The nature of the disease is mostly a mixture of deficiency and excess,and in the later stage of the disease,qi and yin are always depleted.The general principle of treatment in clinic is"anti-cancer and detoxification,strengthening vital energy and dispelling pathological factors".In view of the rise and fall of cancer toxin and the characteristics of different stages of the disease,it is recommended to soothe liver and regulate qi,dissolve phlegm and disperse lumps,reduce stasis and detoxify,benefit qi and nourish yin in the clinical treatment of thyroid carcinoma.Based on the theory of cancer toxin pathogenesis,the pathogenesis evolution and relevant treatment is discussed,in order to provide new ideas for the syndrome differentiation and treatment of thyroid carcinoma.

Pertussis toxin in involves the development of interstitial lung disease in an experimental autoimmune myositis mice modelby inducing the formation of neutrophil extracellular traps / 中华风湿病学杂志

Objective:To test the hypothesis that Pertussis toxin (PTX) can promote the occurrence of interstitial lung disease (ILD) in experimental autoimmune myositis (EAM) model and clarify the potential pathogenic mechanism.Methods:EAM mice model were induced by Skeletal muscle thomogenate with or without PTX, and the relationship between ILD phenotypes and neutrophil extracellular traps (NETs) infiltration was analyzed by histopathological and serological studies in EAM with PTX group and EAM without PTX group. Healthy mice were given PTX alone intraperitoneally to clarify whether NETs formation could be induced in vivo, and neutrophils separated from healthy human blood were intervened with PTX to induce NETs formation in vitro. The data was tested for normality using Shapiro-Wilk. Statistical methods and were analyzed using t-test or ANOVA, and multiple comparisons between different groups were tested using Tukey test. Results:Compared with EAM without PTX group, lung tissues in EAM with PTX group had multiple pathological changes similar to polymyositis/dermatomyositis-related ILD. Nonspecific interstitial pneumonia and usual interstitial pneumonia were the main pathological types. The pulmonary interstitial lesions were accompanied by significant infiltration of NETs; and serum NETs markers levels were obviously elevated in EAM with PTX group, compared with the control group [ n=5, (87±10) ng/ml], cfDNA levels were statistically significantly elevated in both the EAM without PTX group [ n=4, (115±27) ng/ml] and the EAM with PTX group [ n=7, (150±50) ng/ml] ( F=4.24, P=0.038); Cit-H3-DNA levels were elevated in the EAM without PTX group ( n=4, 0.24±0.09), and in the EAM EAM with PTX group ( n=6, 0.33±0.11) compared with the control group ( n=4, 0.13±0.02) ( F=6.21, P=0.016). After PTX intervention, serum cfDNA levels were higher in the PTX group [ n=3, (100±40) ng/ml] than in the control group [ n=3, (45±12) ng/ml, t=2.27, P=0.086]; PTX also induced neutrophils to form NETs in vitro. Conclusion:PTX may promote the development of ILD in EAM mice model by inducing the formation of NETs, indicating that EAM mice can serve as a model for targeting NETs to study the pathogenesis ILD.

Analysis of CHEN Yongcan's Experience in Treating Chronic Atrophic Gastritis with Intestinal Metaplasia Based on the Patho-genesis of"Deficiency in Origin and Toxin Accumulation" / 浙江中医药大学学报

[Objective]To summarize Director CHEN Yongcan's experience in treating chronic atrophic gastritis with intestinal metaplasia the pathogenesis of"deficiency in origin and toxin accumulation".[Methods]Through following Director CHEN Yongcan's outpatient service,sorting out and analyzing typical medical cases,combined with the view of Director CHEN in clinical practice,it summed up his experience in treating chronic atrophic gastritis with intestinal metaplasia from three aspects:core pathogenesis,syndrome differentiation and treatment,prescription and medication,and a proved case was attached to support the treatment.[Results]Chronic atrophic gastritis with intestinal metaplasia is one of the key links in the occurrence and development of gastric cancer.Director CHEN Yongcan believes that the"deficiency in origin and toxin accumulation"is the core pathogenesis of chronic atrophic gastritis with intestinal metaplasia."Deficiency in origin"means deficiency in the spleen and stomach,insufficiency of vital Qi;"toxin accumulation"namely turbidity-toxicity stays stagnation,accumulated and hidden.Taking the cold-heat complex syndrome as the basic point for syndrome differentiation and treatment,it's called for keeping the balance of cold and heat.According to the proportion of deficiency and excess,he treats the disease with the syndrome.The prescription is mainly self-made prescription Shiwei Xiexin Decoction,which can detoxify and benefit vital Qi.If spleen deficiency causes kidney deficiency,kidney-nourishing herbs should be added to solve this condition.If there're Qi and blood stasis,flower herbs are preferred for use.Aiming at the difference between phlegm toxin,stasis toxin and heat toxin,three pairs of triplet herbs which include Cremastrae Pseudobulbus-Salvia chinensis-Actinidia Valvata Dunn,Nidus Vespae-Herba Artemisiae Anomalae-Rhizoma Curcumae and Taraxacum mongolicum-Scutellariae Barbatae Herba-Hedyotis Diffusa are selected for treatment.The syndrome differentiation of the case was spleen deficiency and toxin accumulation,and complex cold-heat.The treatment was invigorating the spleen and detoxifying,and adjusting cold-heat in balance,and Shiwei Xiexin Decoction was used,considering the combination of blood stasis and toxin accumulation,Nidus Vespae-Herba Artemisiae Anomalae-Rhizoma Curcumae were selected.At the follow-up visit,because of obstruction of Qi and blood and imbalance of Qi movement,and Sanhua Baicao Drink to gently promote depression.In the third visit,considering age growth,the liver and kidney were gradually declining,the long-term illness damaged primordial Qi,and the Sijun Zhenyuan Decoction was used to invigorate the spleen and tonify the kidney,consolidate the basis and cultivate primordial Qi.[Conclusion]Director CHEN's experience in differentiating and treating chronic atrophic gastritis with intestinal metaplasia from"deficiency in origin and toxin accumulation"is unique and effective,which is worthy of promotion and learning.

Efficacy comparison of botulinum toxin A injection and extraocular muscle surgery in the treatment of large angle acute acquired concomitant esotropia / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To explore the variance in efficacy between botulinum toxin A(BTA)injection and extraocular muscle surgery in managing large-angle(≥+60 PD)acute acquired concomitant esotropia(AACE).METHODS: A retrospective analysis was conducted on clinical data of 60 patients with AACE treated at our hospital from June 2020 to December 2022. Patients were divided into three groups based on different treatments: 2.5 IU BTA injection group(14 cases), 5.0 IU BTA injection group(29 cases), and surgical group(17 cases). Follow-up was conducted for 6 mo after treatment to observe the degree of strabismus after the correction of refractive error, visual function, treatment effectiveness, and occurrence of complications after BTA injection.RESULTS: At 6 mo post-treatment, the degree of strabismus in the surgical group and the 5.0 IU BTA injection group was lower than that in the 2.5 IU BTA injection group(P<0.017). However, there was no significant difference in the degree of strabismus between the surgical group and the 5.0 IU BTA injection group(P>0.017). The effective rate of the 5.0 IU BTA injection group was higher than that of the 2.5 IU BTA injection group(86% vs 43%, P<0.017). There was no difference in visual function among the three groups(P>0.05). The incidence of complications after treatment was not significantly different between the 2.5 IU BTA injection group and the 5.0 IU BTA injection group(43% vs 52%, P>0.05).CONCLUSION: For AACE patients with esotropia degree ≥+60 PD, bilateral medial rectus injection of 5.0 IU BTA can yield outcomes comparable to traditional extraocular muscle surgery, with the advantages of minimal trauma and simple and convenient operation.

Exploring the Ideas of Traditional Chinese Medicine in the Prevention and Treatment of Tumour Metastasis Exacerbated by Chronic Stress：from the Perspective of Abnormal Tumour Cell Adhesion / 中医杂志

Abnormal tumour cell adhesion is a key step in tumour metastasis， in which weakened homologous and enhanced heterologous adhesion of tumour cells is an important cause of tumour metastasis. Chronic stress can activate the sympathetic nervous system to link and regulate the homologous and heterologous adhesion of tumour cells and exacerbate tumour metastasis. Combining the understanding of traditional Chinese medicine （TCM） and Western medicine on tumour metastasis， it is believed that the mechanism of "qi constraint and stagnation， tumor toxin transmission and retention" in TCM theory is highly related to the abnormal adhesion of tumour cells triggered by chronic stress. Qi constraint and stagnation is closely related to chronic stress and its activation of the sympathetic nervous system， and transmission and retention of tumor toxin explained the mechanism of tumour metastasis due to abnormal adhesion of tumour cells from the perspective of TCM. By regulating the key link of sympathetic nervous system-tumour cell adhesion， application of the formulas of regulating qi and resolving toxin can improve chronic stress and inhibit tumour metastasis.

TU Jinwen's Experience in the Treatment of Severe Influenza Based on the “Heat Toxin Theory” / 中医杂志

To summarize Professor TU Jinwen's clinical experience in the treatment of severe influenza based on the “heat toxin theory”. He believed that “heat toxin” is the main disease mechanism of severe influenza， emphasized the pathogenesis process that toxin enters with the pathogenic qi， heat generates by the toxin， and changes initiate from the toxin， and proposed simultaneous treatment of warmth and toxin and combination of multiple methods as the treatment principles. Syndrome differentiation in clinic should combine with wei-qi-ying-blood. The disease in the early stage located in wei （defensive） and qi level， treated by clearing heat and resolving toxins， releasing the exterior and expelling pathogen， harmonizing the exterior and interior， dredging the bowels with diarrhea， and combining other methods to get rid of the heat and toxin， and modified Self-Prescribed Tuire No. 1 Formula （自拟退热1号方） is recommended； the disease in progression stage located in ying-blood， treated by relieving heat and resolving toxins， and clearing the ying level and cool the blood， with prescriptions as modified Self-Prescribed Tuire No. 1 Formula plus Qingying Decoction （清营汤）， or Xijiao Dihuang Decoction （犀角地黄汤）； the disease in the late stage with of yin fluid consumption， and heat toxin in the blood level， treated by eliminating heat and resolving toxins， and enriching yin and cooling the blood， with prescriptions as modified Shashen Maidong Decoction （沙参麦冬汤） and Zhuye Shigao Decoction （竹叶石膏汤）. At the same time， it is emphasised that heat-clearing and fire-draining method and harmonising methods are important， and that dispelling pathogen should not injure healthy qi， and that the selection of prescriptions and medicines need consider syndrome differentiation and treatment.

The Development and Weight Assignment of the Diagnostic Scale of Turbid Toxin Syndrome： Based on Delphi and Hierarchical Analysis Process / 中医杂志

ObjectiveTo construct traditional Chinese medicine （TCM） diagnostic scale of turbid toxin syndrome in order to provide corresponding reference for the standardization of TCM syndromes and studies. MethodsWe systematically searched the Chinese Medical Dictionary （CMD）， China Knowledge Network （CNKI）， Wanfang Data Knowledge Service Platform （WF） and VIP database for TCM classics and modern literature on turbid toxin syndrome， and initially screened the four diagnosis information of turbid toxin syndrome， established a pool of information entries， and conducted a cross-sectional clinical survey. Discrete trend method， correlation coefficient method， Cronbach's coefficient method， and factor analysis method were applied to objectively screen the entries. The diagnostic scale of turbid toxin syndrome were constructed through three rounds of Delphi method expert survey to determine the scale entries， using hierarchical analysis to get the judgement matrix scores and relative weight of each entry， after passing consistency test and then isometric expansion of the relative weight of the entries to get the weight of each entry and assign the value. ResultsA total of 35 articles were included， 45 entries were obtained after the initial screening. After the clinical investigation， 12 entries were not suitable by the discrete trend method， 23 entries not suitable by correlation coefficient method， 13 entries by the internal consistency screening were removed with the Cronbach's alpha coefficient rising， and 10 entries not suitable by the factor analysis method. Twenty-two entries were retained after objective screening by the combined use of the four statistical methods. The positive coefficients of experts in the three rounds of Delphi method of expert consultation were 96.67%， the coefficients of expert authority were 0.834， 0.856， and 0.867， and the coefficients of co-ordination were 0.126， 0.326， and 0.312， respectively. After consulting with clinical experts， and three rounds of Delphi method survey and hierarchical analysis method weight assignment， the diagnostic scale entries of turbid toxin syndrome were finally established. Primary symptoms： dark red or purple and dusky tongue， yellowish greasy or dry coating （10 points）； sticky and unpleasant stools （8 points）； disharmony of tastes including halitosis， sticky and greasy taste in the mouth， dry mouth and bitter taste in the mouth （6 points）； unfavourable or yellowish or red urination （5 points）； and dark complexion （4 points）. Secondary symptoms： heavy body （3 points）； dizziness （3 points）； profuse， sticky， foul-smelling secretions （2 points）； wiry and slippery， or slippery， or slippery and rapid pulse （2 points）； feeling of hardness in the abdomen （1 point）. ConclusionUsing Delphi method combined with the hierarchical analysis method， combining qualitative and quantitative study， a diagnostic scale of turbid toxin syndrome was initially developed.

Chinese Herbal Enema Combined with Fumigation as Adjunctive Therapy for 60 Cases of Non-dialysis Chronic Kidney Disease Patients of Stage 3-5 with Spleen-kidney Yang Deficiency and Turbid Toxin Blood Stasis Pattern：A Randomized Controlled Trial / 中医杂志

ObjectiveTo observe the clinical efficacy and safety of Chinese herbal enema combined with fumigation as adjunctive therapy for non-dialysis chronic kidney disease （CKD） patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern. MethodsA total of 120 non-dialysis CKD，patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern were randomly divided into treatment group and control group， with 60 cases in each group. The control group received conventional western medical treatment， while the treatment group additionally received Chinese herbal enema combined with fumigation， with enema and fumigation performed alternately， once every other day， three times a week. The treatment course for both groups was 4 weeks. The levels of serum creatinine （Scr）， estimated glomerular filtration rate （eGFR）， and the total score of traditional Chinese medicine symptoms were compared before and after treatment in both groups. The efficacy of traditional Chinese medicine symptoms and clinical efficacy were compared between the two groups after treatment. Adverse reactions in both groups were observed during the treatment period. ResultsThe total score of traditional Chinese medicine symptoms was significantly reduced after treatment in both groups （P＜0.01）. Compared to the control group after treatment， the treatment group showed significant decreases in Scr and the total score of traditional Chinese medicine symptoms， and a significant increase in eGFR （P＜0.05）. The total effective rate of traditional Chinese medicine symptoms in the treatment group （96.67%） was higher than that in the control group （46.67%， P＜0.01）， as well as the total effective rate of clinical efficacy in the treatment group （75.00%） versus that in the control group （28.33%， P＜0.01）. During the treatment period， the vital signs of patients in both groups remained stable， and there were no significant abnormalities in blood routine， urine routine， stool routine， liver function indicators， and electrocardiogram after treatment. ConclusionChinese herbal enema combined with fumigation as adjunctive therapy can significantly alleviate clinical symptoms， improve renal function， and demonstrate good safety for non-dialysis CKD patients of stage 3-5 with spleen-kidney yang deficiency and turbid toxin blood stasis pattern.

Differentiation and Treatment of Malignant Tumors based on the Theory of Ministerial Fire / 中医杂志

The occurrence of malignant tumors is closely related to the ministerial fire. The variant ministerial fire is the fundamental factor of the formation of cancer toxin， and ministerial fire dislocation and hyperactivity are the basis for the generation of variant ministerial fire. When the ministerial fire cannot keep its position or moves without restraint， burning and exuberant， the variant ministerial fire comes out. Under the guidance of the theory of ministerial fire， the basic treatment methods to differentiate and treat malignant tumors are the direct repulsion of variant ministerial fire， and the regulation of dislocated and hyperactive ministerial fire. The method of clearing heat and resolving toxins is often used， taking a large amounts of bitter and cold herbs to reduce variant ministerial fire. For ministerial fire dislocation， ministerial fire depletion， true yang insufficiency， and the ministerial fire failing to rely on， it is common to have symptoms of upper heat and lower cold， for which the treatment method is to benefit the source of the fire， and Modified Yinhuo Decoction （引火汤加减） is commonly used. For insufficient true yin and lack of support for ministerial fire， it is suggested to nourish kidney essence， and the medicinals of enriching yin and boosting kidney are commonly used. In terms of ministerial fire hyperactivity， the treatment method should be nourishing the heart and calming the mind， and Jiaotai Pills （交泰丸） is often used to clear heart and clam the mind， and return fire to its origin. At the same time， methods such as regulating qi， resolving phlegm， clearing fire， and dispelling stasis are used to clear away tangible pathogens， so that the ministerial fire acts in a controlled manner and keeps its position and destiny.
