ABSTRACT

OBJECTIVE@#To explore the genetic basis for a couple with recurrent conceptions of fetus with abnormal longbones, and another couple with a history of omphalocele.@*METHODS@#Genomic DNA was extracted from the peripheral blood samples from both couples. All exons and flanking regions were analyzed with next generation sequencing. Candidate variants were verified by Sanger sequencing.@*RESULTS@#Couple one was found to be heterozygous for, a c.997+1G>T splice-site variant and a missence c.871G>A(p.Glu291Lys) variant of the ALPL gene. Both variants were predicted to be pathogenic and may result in reduced function or loss of alkaline phosphatase. For couple two, the wife was found to harbor a novel c.637_652 delins CCC variant of the CDKN1C gene. This deletion-insertion variant resulted in frame-shift and loss of function (p.Ala213Profs*55) of the CDKN1C protein. Maternally inherited CDKN1C LOF variant has been found to underlie Beckwith-Wiedemann syndrome (BWS), which may manifest as omphalocele.@*CONCLUSION@#Dispite the lack the direct proof from the lost fetuses, the variants of ALPL and CDKN1C genes can explain the recurrence of fetal malformations for both couples.

ABSTRACT

OBJECTIVE@#To explore the methods and efficacy of unilateral extra-pedicle precision puncture percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty(PKP) by digital subtraction angiography (DSA) for the treatment of osteoporotic vertebral compression fractures (OVCFs).@*METHODS@#The clinical data of 68 patients with osteoporotic vertebral compression fractures treated from August 2015 to December 2018 were retrospectively analyzed. There were 20 males and 48 females, aged 56 to 90(73.5±8.0) years, 40 cases of double segments, 28 cases of three segments, a total of 168 vertebrae. All the patients were performed PVP orPKP through unilateral extra pedicle precision puncture under the guidance of DSA. The vertebrae were distributed in T@*RESULTS@#All the punctures were successful in 68 patients. All the puncture needles reached the midline of vertebral body, and the bone cement was well dispersed in the vertebral body with symmetrical distribution. The operation time was 35 to 60 (41.6±3.2) minutes, and there was no puncture complications. The injection volume of bone cement was 3 to 5 (3.6±0.5) ml in each vertebra. There were 8 cases of bone cement leakage, with a leakage rate of 11.76%. All 68 patients were followed up from 12 to 27 (14.3±3.5) months in the study. VAS score and ODI at 3 days after surgery and at final follow-up time were significantly improved (@*CONCLUSION@#PVP or PKP under the guidance of DSA via a unilateral extrapedicular approach with precision puncture can effectively relieve pain, restore vertebral body height and spinal function, which is a safe, fast and effective method in the treatment of osteoporotic vertebral compression fractures.

ABSTRACT

Objective:To get comprehensive understanding of the registration characteristics of global clinical trials of coronavirus disease 2019(COVID-19) based on the ClinicalTrials. gov and the Chinese Clinical Trial Registry (ChiCTR).Methods:The clinical trials of COVID-19 in the ClinicalTrials.gov and ChiCTR were retrieved. The search start time was unlimited, with deadlines of 14 December, 2020 and 19 March, 2021, respectively. The registration numbers, registration submitted time, country/region distribution, recruitment status, study types, number of recruits, research phases, and other aspects were analyzed by using bibliometric methods.Results:As of March 19, 2021, there were 775 clinical trials in ChiCTR. As of December 14, 2020, there were 4 137 clinical trials in the ClinicalTrials.gov, and 3 157(76.31%) of the clinical trials recruited subjects who were aged≥18 years old. There were 2 347 intervention trials and 1 759 observational trials. The intervention measures mainly included drugs, biologics and medical devices. The numbers of recruits were 110(48, 308) cases for interventional studies, and 300(100, 1 000) cases for observational trials. The interventional research phases were mainly phaseⅡ (570 items) and phase Ⅲ (358 items). Totally, 50.33%(2 082/4 137) of the clinical trials were under recruitment, 13.10%(542/4 137) had been completed. Among the interventional studies, 729(31.06%) were multi-center studies, with the center numbers of 5(2, 15).Conclusions:At present, there are a large number of clinical trials with various intervention measures in the world. However, the number of recruits is unreasonable, and multi-center study with multi-agency cooperation is insufficient.

ABSTRACT

Objective:To explore the relationship between uric acid (UA), transforming growth factor-β (TGF-β), nerve growth factor (NGF) and bipolar disorder (BPD) and its clinical significance.Methods:From January 2019 to January 2020, 100 BPD patients in the First Hospital of Hebei Medical University were selected as the observation group, and 100 healthy subjects were selected as the control group. The general data, serum UA, TGF-β, and NGF levels were compared between the two groups, and the factors affecting the incidence of BPD and the correlation between serum UA, TGF-β, and NGF were analyzed. And the diagnostic value of serum UA, TGF-β, and NGF on BPD and BPD patients with mixed episodes of depression and mania was analyzed.Results:There were statistically significant differences in the levels of fasting blood glucose, triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), UA, TGF-β and NGF between the two groups ( P<0.05). Logistic regression analysis showed that fasting blood glucose, TG, TC, HDL-C, LDL-C, UA, TGF-β, and NGF levels were all influencing factors of BPD ( P<0.05). Serum UA of BPD patients was negatively correlated with TGF-β and NGF ( r=-0.744, -0.754, P<0.05), and TGF-β was positively correlated with NGF ( r=0.824, P<0.05). The area under the curve (AUC) values of serum UA, TGF-β, and NGF in the diagnosis of BPD were all high, especially the highest in combined diagnosis, reaching 0.844. The serum UA level of the mixed episode group was higher than that of the single episode group, and the serum TGF-β and NGF levels were lower than that of the single episode group, the difference was statistically significant ( P<0.05). Serum UA, TGF-β, and NGF levels had high diagnostic value for depression and manic mixed episodes in BPD patients, and the combined diagnosis had the highest AUC value, reaching 0.770. Conclusions:The serum UA, TGF-β, and NGF of BPD patients are all abnormally expressed, which may be biomarkers of BPD, and there is a certain correlation between the indicators. The combined examination can improve the diagnostic value of mixed episodes of depression and mania in BPD and BPD patients, and provide a basis for early diagnosis and treatment.

ABSTRACT

Objective To understand the current status of osteoporosis risk and influencing factors for residents from 30 to 65 years old in typical hot spring areas in Guizhou province, and to provide a theoretical basis for reducing the risk of osteoporosis and the prevention of osteoporosis in the population. Methods A health questionnaire for residents in typical hot spring areas in Guizhou, osteoporosis risk test questions, Pittsburgh sleep quality index(PSQI), etc were used. A face-to-face survey of 3 708 residents was conducted, and logistic regression was used to analyze the influencing factors of osteoporosis risk in hot spring areas. Results 2 403(64.81%)residents of 3 708 people surveyed were at risk of osteoporosis, of whom 1 434(87.4%)males and 969 females(47.1%)had a higher risk of osteoporosis (χ2=652.4, P < 0.001). As age increased, more residents were at risk of osteoporosis(χ2=273.4, P < 0.001), and numbers of residents of 30-39 years old, 40-59 years old, and above 60 years of age at risk of osteoporosis were 319(49.2%), 1 572(62.9%), and 512(93.6%). Male osteoporosis risk was negatively correlated with an education level of undergraduate and above(OR=0.37, 95%CI: 0.19-0.73). Age 40-59(OR=1.54, 95%CI: 1.07-2.22), 60 and above(OR=6.39, 95%CI: 2.76-14.79), and sleep disorders(OR=1.59, 95%CI: 1.08-2.35)may increase the risk of osteoporosis in male residents in hot spring areas. Less oil in daily diet may increase the risk of osteoporosis in women(OR=1.70, 95%CI: 1.23-2.36). Age 40-59(OR=1.54, 95%CI: 1.17-2.03), over 60 and above(OR=16.24, 95%CI: 10.10-26.12), and sleep disorders(OR=1.84, 95%CI: 1.48-2.28)were positively correlated with risk of osteoporosis in women. Women with junior high school degree(OR=0.61, 95%CI: 0.47-0.80), high school degree(OR=0.57, 95%CI: 0.37-0.89)and undergraduate degree and above(OR=0.59, 95%CI: 0.39-0.98)had a lower risk of osteoporosis than women who were illiterate or semi-illiterate. The osteoporosis risk test questions showed that smoking, heavy drinking, and erectile dysfunction and reduced sexual desire were the main sources of osteoporosis risk in men. Menopause before the age of 60, ≤45 years old, no milk and no calcium supplements, parents with osteoporosis or bone fractures were the major risk sources of osteoporosis in women. Conclusion The risk of osteoporosis among male residents from 30 to 65 years old in typical hot spring areas in Guizhou province is higher than that among women. Education of osteoporosis prevention should be strengthened among local residents to promote healthy behaviors and lifestyles.

ABSTRACT

Objective To investigate the prevalence of osteoarthrosis and the association between hot spring bathing and osteoarthrosis among local adults in typical hot spring areas of Guizhou Province. Methods A face-to-face questionnaire survey was conducted among residents aged from 30 to 65 in five typical hot spring areas, including Xifeng(Xifeng County, Guiyang), Jianhe(Jianhe County, Qiandongnan), Fodingshan(Shiqian County, Tongren), Guiyu(Wudang District, Guiyang)and Huishangu(Suiyang County, Zunyi). Residents' basic information, bone and joint diseases prevalence, hot spring bathing, and other health-related behaviors were investigated in this study. The prevalence of local bone and joint diseases was analyzed, and binary logistic regression was used to calculate OR(95%CI)to analyze the association between hot spring bathing and bone and joint diseases. Results A total of 3 708 adults(1 648 males and 2 060 females)were included as the statistical analysis survey subjects, and 794 people reported bone and joint diseases, accounting for a prevalence rate of 21.41%, 95% CI: 0.201-0.227. The prevalence of females(24.56%)was higher than that of males(17.48%)(P < 0.001). The prevalence rates of diseases increased with age(χtrend2=130.265, P < 0.001). There were also statistically significant differences in the prevalence rate of bone and joint diseases among different genders, age groups, occupations, education levels, and smoking behaviors(P < 0.05). After gender, age, occupation, education and smoking were adjusted for, compared with the group who never took hot spring baths, participants who took hot spring baths occasionally(OR=0.793, 95%CI: 0.631-0.996)and frequently(OR=0.713, 95%CI: 0.536-0.948)were associated with a lower risk of bone and joint diseases. Conclusion The prevalence of osteoarthrosis is 21.41% in the typical hot spring areas of Guizhou Province. Older or females have a higher risk of prevalence of bone and joint diseases. Hot spring bathing may be associated with a lower risk of bone and joint diseases.

ABSTRACT

Objective To investigate the association between hot spring bathing behavior and hypertension and understand the mediation effect of sleep quality problems on the association. Methods A cross-sectional survey was conducted among adults aged 30 to 65 living and working around five hot springs in Guizhou Province, employing a self-designed questionnaire on the health status and hot spring bathing, and 3 708 qualified questionnaires were collected. Participants were divided into three groups according to their frequency of hot spring bathing: never, occasionally, and frequently. Stratified via sex and sleep quality, the binary logistic regression model was used to analyze the association between different hot spring bathing frequencies and self-reported hypertension. Results Significant difference was detected in the self-reported hypertension between groups who never bathe(13.7%), who occasional bathe(9.4%)and who frequently bathe(8.5%)among female participants(χ2=10.460, P=0.005). However, no significant difference was found among different bathing groups in males. Furthermore, multivariate analysis showed that compared with no bathing, occasional(OR=0.692)and frequent (OR=0.594)hot spring bathing were associated with lower hypertension prevalence among female population, and female groups of occasional and frequent bathing with sleep quality problems had smaller OR(OR=0.571 and 0.406, respectively). After sleep quality problems were included, hot spring bathing was still associated with lower hypertension risk, and the OR values of occasional bathing and frequent bathing groups were 0.723 and 0.611, respectively. The sleep quality problems of female population played a partial mediating role in the association between hot spring bathing and hypertension, and the relative mediating effects of occasional bathing and frequent bathing with hypertension were both statistically significant(Zm=-2.022 and -1.995, P < 0.05), which accounted for 34.34% and 30.15% of the total effects, respectively. Conclusion Regular hot spring bathing may play an auxiliary role in the prevention of hypertension, and it may provide a stronger protection for women, and especially those with sleep quality problems. Sleep quality problems may explain part of the association between hot spring bathing and hypertension in female population.

ABSTRACT

Objective To analyze the association between hot spring bathing and the quality of life of smokers living in typical hot spring areas of Guizhou to make suggestions on improving their quality of life. Methods The study is a cross-sectional study whose data was collected by questionnaires. The WHO Quality of Life Scale(WHO QOL-BREEF)was used to measure quality of life. Results The quality of life in the psychological domain(14.09±1.83 vs 13.79±1.82, P < 0.05)and the environmental domain(12.70±1.84 vs 12.37±1.67, P < 0.05)among smokers who took hot spring baths was significantly higher than that among those who did not. After adopting ordinary logistic regression model to adjust for other factors, for the physical domain, the odd of scoring"good"in the WHO scale in group of smokers who took hot spring baths less that once a month was 0.70 lower than that in those who took baths at least once a month(OR=0.70, 95%CI: 0.54-0.91). In psychological domain, the odd of the group of smokers who did not take hot spring baths was 0.65 lower than that in those who took baths at least once a month(OR=0.65, 95%CI: 0.47-0.90). And the odd of the group of smokers who bathed less than once in a month was 0.71 lower than those who bathed at least once a month(OR=0.71, 95%CI: 0.54-0.92). Conclusion There is a positive relationship between hot spring bathing and quality of life, which prompts that people who smoke take hot spring baths to improve their quality of life.

ABSTRACT

Objective To investigate hot spring bathing behavior and chronic disease prevalence of residents aged 30 to 65 in typical hot spring areas of Guizhou Province. Methods Totally 3 708 individuals between 30 and 65 in five typical hot spring areas of Guizhou Province were included in this study. Their hot spring bathing behavior and chronic disease prevalence were recorded. Unconditional logistic regression was used to analyze the association between hot spring bathing and the incidence of chronic diseases. Results 71.3% of the residents in the hot spring areas had bathed in hot springs, with the proportion higher in males than females(χ2=92.856, P < 0.001). 76.3% of people took hot spring baths fewer than or equal to 6 times per year, 30.8% of residents often chose to take hot spring baths in the evening, and 37.6% of the residents took hot spring baths for 21-40 minutes. Bathing was more common in winter. 11.5% and 17.9% of the residents added other substances and used hot spring facilities, and most of them added traditional Chinese medicine and used the sauna. 46.6% and 41.6 % of the residents took hot spring baths to relax and relieve fatigue. The self-reported prevalence rate of chronic diseases was 522.1‰, and the top five single diseases were lumbar intervertebral disc disease(119.7‰), hypertension(118.1‰), urinary calculus(77.7‰), cervical intervertebral disc disease(53.7‰)and osteogenesis(44.5‰). Compared with those who never bathed in hot springs, taking hot spring baths 7-11 times a year was negatively correlated with chronic diseases.(OR=0.551, 95%CI: 0.345-0.879). Conclusion Hot spring bathing is popular in typical hot spring areas of Guizhou Province, but its frequency is not high. The overall prevalence of chronic diseases is relatively high, and the order of most prevalent chronic diseases is different from that in other areas. Proper hot spring bathing is negatively correlated with chronic diseases.

ABSTRACT

OBJECTIVE@#To provide genetic counseling for a couple with recurrent detection of fetal structural abnormality during second trimester pregnancy.@*METHODS@#The fetal tissue and peripheral blood samples of the couple were subjected to G banded chromosomal analysis, copy number variation sequencing (CNV-seq) and fluorescence in situ hybridization (FISH) assays.@*RESULTS@#CNV-seq has detected a 6.59 Mb duplication at 7p22.3-p22.1 and a 3.81 Mb deletion at 4p16.3 in the fetal tissue, though conventional karyotyping results of both parents were normal. FISH has confirmed that the father has harbored a cryptic translocation of t(4;7)(7p+,4q+,4p+,7q+).@*CONCLUSION@#The ultrasonographic abnormality of the fetuses may be attributed to the 7p microduplication and 4p microdeletion derived from the cryptic translocation carried by the father. Reciprocal translocation of tiny chromosomal segments should be suspected for couples with recurrent adverse pregnancies but apparently normal karyotypes.

ABSTRACT

Objective:To investigate the genetic etiology of a pedigree with autosomal recessive congenital ichthyosis.Methods:Whole-exome sequencing was performed in a collodion baby, and Sanger sequencing was conducted to verify gene mutations. The PolyPhen-2, PROVEAN and Mutation Taster softwares, as well as protein homology modeling methods, were used to predict effects of gene variants; real-time fluorescence-based quantitative PCR and Western blot analysis were performed to analyze the effect of mutations on allelic mRNA and protein expression.Results:Whole-exome sequencing and Sanger sequencing confirmed a mutation c.919C>T (p.Arg307Trp) in exon 6 and a mutation c.1019G>A (p.Gly340Glu) in exon 7 of the TGM1 gene in the infant, which were inherited from his mother and father respectively. Bioinformatics analysis suggested that both the two mutations were harmful to protein structures, which were further supported by protein homology modeling. In vitro experiments showed that there was no significant difference in the mRNA expression of the TGM1 gene between the 293T cells transfected with wild-type plasmids and those transfected with mutant plasmids containing the mutation c.919C>T or c.1019G>A ( t=1.97, 1.28, P=0.12, 0.27, respectively) , but the TGase1 protein expression significantly decreased in the 293T cells transfected with the mutant TGM1 plasmids. Conclusion:The mutations c.919C>T and c.1019G>A in the TGM1 gene may be the molecular genetic etiology of severe ichthyosis in the infant, and the missense amino acids encoded by the two mutations may affect the TGase1 protein function by destroying its structure.

ABSTRACT

OBJECTIVE:To ex plore the protective effects of Longbie capsule contained serum (called“LBJN”for short )on the apoptosis of chondrocytes induced by YAP inhibitor verteporfin and its mechanism. METHODS :Primary human knee osteoarthritis(OA)chondrocytes were extracted by two-step enzymatic digestion ,and then identif ied by toluidine blue staining and type Ⅱ collagen immunofluorescence staining. The effects of 2,5 μmol/L verteporfin alone or combined with 5%LBJN on cell apoptosis were detected by flow cytometry. Solvent control (0.1% DMSO)and 5% LBJN were set. Western blot assay was adopted to detect the expression of apoptosis related proteins (YAP,Bcl-2,cleaved-caspase-3) after treated with 0.1%DMSO(solvent control ),2 μmol/L verteporfin,2 μmol/L verteporfin+5%LBJN 和 0(blank control ),2.5% LBJN and 5% LBJN for 48 h. The expression of autophagy related proteins (mTOR,Beclin-1,LC3A/B) after treated with 0 (blank control ),2.5%,5% LBJN for 48 h were det ected by Western blot assay. RESULTS :The isolated cells accorded with the characteristics of chondrocytes. Compared with 0.1%DMSO, the apoptosis rates of cells were increased significantly after treated with 2,5 μmol/L verteporfin(P<0.05),and the effects of the two concentrations were similar (P>0.05). Compared with verteporfin alone ,2,5 μmol/L verteporfin combined with 5%LBJN could significantly decrease the apoptotic rate of cells (P<0.05). Compared with 0.1%DMSO,the protein expression of YAP and Bcl-2 were decreased significantly after treated with 2 μ mol/L verteporfin (P<0.05), while the protein expression of cleaved-caspase-3 were increased significantly (P<0.05). Compared with 2 μmol/L verteporfin,protein expression of YAP and Bcl-2 were increased significantly after treated with 2 μmol/L verteporfin+5%LBJN(P<0.05),while the protein expression of cleaved-caspase-3 were decreased significantly (P<0.05). Compared with blank control ,the protein expression of YAP ,Bcl-2 and Beclin-1 were increased significantly after treated with 2.5%,5%LBJN(P<0.05),while protein expression of cleaved-caspase- 3 and mTOR were decreased significantly (P<0.05). CONCLUSIONS :LBJN can block the apoptosis of chondrocytes induced by YAP inhibitor verteporfin ,and its mechanism may be related to regulating the expression of apoptosis related proteins and enhancing autophagy of chondrocytes.

ABSTRACT

This study aims to investigate the preventive effect of Dendrobium officinale in LPS-induced intestinal mucosal damage. Forty SPF-grade C57 BL/6 J male mice were randomly divided into normal group(NC), model group(LPS), and two superfine powder groups of Dendrobium officinale(DOF)(DOF-L, 0.30 g·kg~(-1)and DOF-H, 0.60 g·kg~(-1), respectively), with 10 mice in each group. DOF superfine powder suspension was given via oral administration to mice for 7 days, while the mice in NC and LPS groups received the same volume of saline for 7 days. On the eighth day, the mice in LPS group and DOF treatment groups were injected with LPS(5 mg·kg~(-1)) by intraperitoneal injection to establish the intestinal mucosal injury model, while the mice in NC group were injected with the same volume of sterile saline in the same manner. Six hours after injection with LPS or saline, plasma and the intestinal tissue were collected. The diamine oxidase(DAO) and D-lactate levels in plasma were detected with a biochemical method. The levels of proinflammatory factors interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in plasma were detected by ELISA. The histomorphology and ultrastructure of mouse ileum tissues were observed by hematoxylin-eosin(HE) staining in optical microscope and transmission electron microscope(TEM). The expression and distribution of tight junction(TJ) proteins claudin-1, occludin and F4/80 were detected by immunohistochemistry while the protein expression levels of Toll-like receptor 4(TLR-4) and nuclear factor kappa B p65(NF-κB p65) in jejunum were detected by Western blot. The experimental results showed that continuous intragastric administration of D. officinale superfine powder for 7 days obviously alleviated the damage and ultrastructural changes of intestinal mucosa induced by LPS; significantly decreased DAO and D-lactate levels in plasma in model group(P<0.05); up-regulated the protein expression of claudin-1 and occludin in ileum tissues; down-regulated the protein expression of TLR-4 and NF-κB p65 in jejunum tissues(P<0.01); significantly decreased TNF-α and IL-6 levels in plasma(P<0.05); and decreased the infiltration of F4/80~+ macrophage cells. Our results suggested that D. officinale had significant protective effects on LPS-induced intestinal mucosal damage and reduced intestinal permeability. The mechanism might be related to its effects of inhibiting inflammation via TLR-4/NF-κB p65, and up-regulating the expression of tight junction proteins.

ABSTRACT

By reviewing the relevant literature in recent years, this paper analyzes the transformation and conduction of moxibustion physical signals, and explores the action mechanism of moxibustion. It is found that the different molecular targets activated by moxibustion photothermal signal are the keys to transform stimulation signal into biological signal. Photothermal signal transmits signal through neuroendocrine immune system and produces a series of biological reactions, thus regulating the functions of various systems of the body.

ABSTRACT

Existen diversas condiciones anatómicas o alteraciones mucogingivales que pueden afectar tanto el normal funcionamiento como la estética gingival de piezas dentarias e implantes dentales. Si bien los tratamientos de estas condiciones se han realizado tradicionalmente con bisturí, el desarrollo tecnológico ha permitido que actualmente se pueden realizar con láser. Existen diferentes tipos de láser, siendo el diodo uno de los más utilizados debido a su menor tamaño, portabilidad, fácil configuración y menor costo. El láser ha adquirido mayor popularidad en cirugías de tejido blando dado sus múltiples beneficios: menor tiempo operatorio, control del sangrado y de la hemostasia, reducción de la cantidad de anestesia, posibilidad de no requerir suturas y minimización del dolor e inflamación postquirúrgica. El propósito de este trabajo es presentar la resolución de tres casos clínicos a los cuales se les realizaron los procedimientos de frenectomía labial, remoción de melanosis gingival y resección de fibroma irritativo mediante el uso de láser diodo. Para desarrollar todos los procedimientos se utilizó un equipo de láser diodo de 940 nm (Biolase®, USA) con una potencia que varió entre 2 y 2.5 W en modo continuo utilizando una pieza quirúrgica con una punta de 300 µm (E 3-4), la que fue activada antes de empezar. Posterior a la cirugía se bioestimuló para disminuir el dolor y edema postoperatorio utilizando la punta de dolor a 4 W por 30 segundos a una distancia de 1 cm directo en la zona intervenida a todos los casos. La conclusión arroja que en todos los casos, el láser de diodo permitió un resultado exitoso. El procedimiento fue seguro, la técnica fue sencilla y de tiempo clínico reducido. El postoperatorio ocurrió con ausencia de dolor o molestias, generando una mayor satisfacción del paciente. Cabe señalar que la técnica depende de la habilidad del profesional que la realiza.


There are various anatomical conditions or mucogingival alterations that can affect the normal functioning and the gingival aesthetics of teeth and dental implants. Although the treatments of these conditions have been traditionally performed with a scalpel, technological development has allowed that they can be now performed with lasers. There are different types of lasers, being the diode one of the most used due to its smaller size, portability, easy configuration, and lower cost. The laser has become more popular in soft tissue surgeries due to its multiple benefits: shorter operating time, control of bleeding and hemostasis, reduction in the amount of anesthesia, possibility of not requiring sutures, and minimization of post-surgical pain and inflammation. The purpose of this work is to present the resolution of three clinical cases which underwent labial frenectomy procedures, removal of gingival melanosis and resection of irritative fibroma using diode laser. To develop all the procedures, a 940 nm diode laser equipment (Biolase®, USA) was used with a power that varied between 2 and 2.5 W in continuous mode, using a 300 µm tip (E 3-4), which was activated before starting. After surgery, biostimulation was carried out to reduce postoperative pain and edema using the pain tip at 4 W for 30 seconds at a distance of 1 cm directly in the operated area in all cases. In all cases, the diode laser allowed a successful result. The procedure was safe, the technique was simple, and the clinical time was short. The postoperative period occurred with the absence of pain or discomfort, generating greater patient satisfaction. It should be noted that the technique depends on the skill of the professional who performs it.
