RESUMO

@#Pediatric malocclusion is common in dentistry. Some children with malocclusion combined with obstructive sleep apnea-hypopnea syndrome (OSAHS) often fail to receive appropriate treatment due to a lack of multidisciplinary diagnosis and treatment. It can cause abnormal ventilation during sleep, affecting the central nervous system and cardiovascular development and even causing neurological and behavioral problems. Pediatric OSAHS is caused by the narrowing of the upper respiratory tract, characterized by specific facial bone characteristics and neuromuscular factors and correlated with malocclusion. Due to its diverse clinical manifestations and etiology, the diagnosis and treatment of pediatric OSAHS require an interdisciplinary, personalized, and specialized approach. Questionnaires and physical examinations can be used for preliminary screening. Moreover, children's stomatology and otorhinolaryngology examinations are the basis for disease diagnosis. Polysomnography (PSG) is currently the direct diagnostic method. There are various treatment methods for OSAHS in children, and for OSAHS caused by adenoid tonsil hypertrophy, adenoidectomy and tonsillectomy are the main treatments. Othodontic treatment including mandibular advancement and rapid maxillary expansion et al is also effective for OSAHS in children with malocclusion. Currently, there is limited research on the correlation between childhood malocclusion and OSAHS, and multidisciplinary combination therapy may improve the cure rate, but there is a lack of sufficient evidence. In the future, the pathogenesis of OSAHS should be further elucidated, and research on multidisciplinary combination therapy should be promoted to achieve early intervention and treatment for potential and existing patients.

RESUMO

Objective:To assess the value of S-Detect and contrast-enhanced ultrasound (CEUS) in the differential diagnosis of Breast Imaging Reporting and Data System(BI-RADS) 4 breast lesions.Methods:A total of 104 breast lesions in 100 patients diagnosed as BI-RADS category 4 by conventional ultrasound were prospectively enrolled, and all of them were received S-Detect and CEUS examination at the same time. Taking pathology as the gold standard, ROC curve was constructed to compare the diagnostic efficacy of conventional ultrasound, S-Detect, CEUS and their combination.Results:Among the 104 BI-RADS category 4 breast lesions, 63 were benign and 41 were malignant. The sensitivities of conventional ultrasound, S-Detect, CEUS and S-Detect combined with CEUS were 73.17%, 87.80%, 87.80%, 90.24%; the specificities were 57.14%, 60.32%, 68.25%, 77.78%; the positive predictive values were 52.63%, 59.02%, 64.29% and 72.55%; the negative predictive values were 76.60%, 88.37%, 89.59% and 92.45%; the accuracies were 63.46%, 71.15%, 75.96% and 82.69%; and the areas under the ROC curve (AUC) were 0.652, 0.741, 0.780 and 0.840. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of S-Detect and CEUS diagnosis were improved compared with conventional ultrasound. The AUC of combined diagnosis was higher than that of S-Detect, CEUS alone, and the differences were statistically significant(all P<0.05). The AUC of CEUS was higher than that of conventional ultrasound, and the difference was statistically significant ( P<0.05). There were no significant differences in AUC between any two of other groups (all P>0.05). Conclusions:The combined application of S-Detect and CEUS could achieve complementary advantages, which is of great significance for the differential diagnosis of benign and malignant in BI-RADS 4 breast lesions.

RESUMO

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

RESUMO

Objective:To study the clinical features, treatment, and prognostic features of Kaufman Oculocerebrofacial syndrome.Methods:The clinical characteristics of a newborn with Kaufman Oculocerebrofacial syndrome admitted to the neonatal unit of Guiyang Maternal and Child Health Care Hospital was reported. Using "Kaufman Oculocerebrofacial syndrome", "Blepharophimosis-ptosis-intellectual disability syndrome" and "UBE3B gene" as keywords, databases including CNKI, VIP database, Wanfang database, Chinese medical journals full-text database, PubMed, Web of Science database and Embase database were searched from the date of establishment to June 2022. The clinical characteristics, treatment and prognosis of Kaufman Oculocerebrofacial syndrome from published literature were summarized.Results:The proband was a boy presenting with small lid fissure, wide eye spacing and feeding difficulties. Whole exome sequencing revealed compound heterozygous mutation in the UBE3B gene, c.1445_1448dupTCAC inherited from his father and c.1703dupA inherited from his mother, both variants had not been reported in the domestic and foreign literature thus far. A total of 34 newborn cases were summarized from 11 case reports, including this report. The main clinical manifestations were developmental delay (35/35), peculiar facial features (35/35), narrow eye slits (35/35), feeding difficulties (33/35), ear abnormalities (33/35), hypotonia (32/35), mouth abnormalities (31/35), breathing difficulties (26/35), small jaws (25/35) and low birth weight (16/35).There is no effective treatment available, and a total of 4 cases followed up to over 16 years old have been reported, all of which have severe mental retardation, language deficiency, along with other serious neurological diseases.Conclusions:when children exhibit symptoms such as narrow eye fissures, feeding difficulties, hypotonia, developmental delays, and peculiar facial features in the neonatal period, whole exome sequence can be used to aid diagnosis and evaluate for Kaufman Oculocerebrofacial syndrome. Families with children of Kaufman Oculocerebrofacial syndrome may undergo prenatal diagnosis based on genetic findings.

RESUMO

Tibet orbivirus (TIBOV) was identified as a novel orbivirus in 2014. Antibodies against TIBOV were detected in cattle, Asian buffalo, and goats, while all the sequenced TIBOV strains were isolated from mosquitos and Culicoides. The known TIBOV strains have been classified into four putative serotypes. In this study, two TIBOV strains isolated from Culicoides spp. in Shizong County of Yunnan Province, China, were fully sequenced. The phylogenetic analysis of outer capsid protein 2 (VP2) indicated that these two viral strains belong to two novel putative serotypes of TIBOV. The updated putative serotypes may help in an investigation of the distribution and virulence of TIBOV.

RESUMO

For the first time, this study evaluated the gender differences and mechanisms of the antidepressant effects of raw Rehmanniae Radix(RRR) based on the classic depression model with traditional Chinese medicine syndrome of Yin deficiency and internal heat. The depression model with Yin deficiency and internal heat was established by the widely recognized and applied method of thyroxine induction of the classic depression model with Yin deficiency and internal heat(chronic unpredictable mild stress). Male and female mice were simultaneously treated with RRR. The study analyzed indicators of nourishing Yin and clearing heat, conventional antidepressant efficacy test indicators, and important biomolecules reflecting the pathogenesis and prevention and treatment mechanisms of depression, and conducted a correlation analysis of antidepressant efficacy, Yin-nourishing and heat-clearing efficacy, and biological mechanism in different genders, thereby comprehensively assessing the antidepressant effects of RRR on depression of Yin deficiency and internal heat, as well as its gender differences and mechanisms. RRR exhibited antidepressant effects in both male and female mouse models, and its antidepressant efficacy showed gender differences, with a superior effect observed in females. Moreover, the effects of RRR on enhancing or improving hippocampal neuronal pathology, nucleus-positive areas, postsynaptic dense area protein 95, and synaptophysin protein expression were more significant in females than in males. In addition, RRR significantly reversed the abnormal upregulation of nuclear factor(NF)-κB/cyclooxygenase 2(COX2)/NOD-like receptor thermal protein domain associated protein 3(NLRP3) pathway proteins in the hippocampus of both male and female mouse models. The antidepressant effects of RRR were more pronounced in depression female mice with Yin deficiency and internal heat syndrome, possibly due to the improvement of neuronal damage and enhancement of neuroplasticity. The antidepressant mechanisms of RRR for depression with Yin deficiency and internal heat syndrome may be associated with the downregulation of the NF-κB/COX2/NLRP3 pathway to reduce neuronal damage and enhance neuroplasticity.

RESUMO

Objective:To investigate the ultrasound characteristics of benign and malignant endometrial lesions in postmenopausal women terminology.Methods:Patients with endometrial lesions who underwent transvaginal ultrasound examination in Beijing Tiantan Hospital affiliated to Capital Medical University from January 2019 to November 2021 were selected.Pathological diagnosis after surgery was used as the gold standard, and endometrial lesions were divided into a benign group(including endometrial hyperplasia and endometrial polyps)and a malignant group(endometrial cancer)according to surgical pathology results.Endometrial thickness and Doppler flow parameters were compared between the benign group and the malignant group.The chi-square test was used to compare the echogenicity, the presence or absence of cystic areas, the integrity of the endometrial-myometrial junction, the blood flow score, and the blood supply vessels between the benign and malignant groups.A prediction model was established according to the ultrasonic characteristics.Results:A total of 136 participants received surgery at our hospital with definitive pathological diagnoses, including 72 patients in the benign group and 64 patients in the malignant group.Peak systolic velocity(PSV) and end diastolic velocity(EDV) in malignant lesions were higher than those in benign lesions[(28.75±14.66)cm/s vs.(22.94±13.62)cm/s, (14.75±8.10)cm/s vs.(11.56±6.21)cm/s]. The thickness of malignant lesions was significantly greater than that of benign lesions[(19.31±8.97)mm vs.10.14±4.31)mm], and the blood flow resistance index was lower than that of benign lesions(14.75±8.10 vs.11.56±6.21). The differences were statistically significant( t=2.393, 2.597, 7.452, 2.028, all P<0.05). The prediction model was established based on the above ultrasonic characteristics.The area under the ROC curve for ultrasound physicians to diagnose benign and malignant endometrial lesions was 0.905( P<0.001), indicating that the prediction model had high diagnostic value. Conclusions:Both benign and malignant endometrial lesions in postmenopausal women have different ultrasonic characteristics.Malignant lesions tend to have a larger lesion thickness, an interrupted or irregular endometrial-myometrial junction, higher blood flow signal scores, and multiple blood supply patterns.The ultrasonic prediction model has high diagnostic value for benign and malignant endometrial lesions.

RESUMO

Obtaining high-quality embryos is one of the key factors to improve the clinical pregnancy rate of assisted reproductive technologies (ART). So far, the clinical evaluation of embryo quality depends on embryo morphology. However, the clinical pregnancy rate is still low. Therefore, new indicators are needed to further improve the evaluation of embryo quality. Several studies have shown that the decrease of sperm-specific protein actin-like 7A (ACTL7A) leaded to low fertilization rate, poor embryo development, and even infertility. The aim of this study was to study whether the different expression levels of ACTL7A on sperm can be used as a biomarker for predicting embryo quality. In this study, excluding the factors of severe female infertility, a total of 281 sperm samples were collected to compare the ACTL7A expression levels of sperms with high and low effective embryo rates and analyze the correlation between protein levels and in-vitro fertilization (IVF) laboratory outcomes. Our results indicated that the ACTL7A levels were significantly reduced in sperm samples presenting poor embryo quality. Furthermore, the protein levels showed a significant correlation with fertilization outcomes of ART. ACTL7A has the potential to be a biomarker for predicting success rate of fertilization and effective embryo and the possibility of embryo arrest. In conclusion, sperm-specific protein ACTL7A has a strong correlation with IVF laboratory outcomes and plays important roles in fertilization and embryo development.

RESUMO

OBJECTIVE@#To explore the application value of next generation sequencing (NGS) in preimplantation genetic diagnosis of α/β complex thalassemia couple.@*METHODS@#The coding regions of α-globin genes (HBA1, HBA2) and β-globin gene (HBB) were selected as the target regions. The high-density and closely linked single nucleotide polymorphism (SNP) sites were selected as the genetic linkage markers in the upstream and downstream 2M regions of the gene. After NGS, the effective SNP sites were selected to construct the haplotype of the couple, and the risk chromosome of the mutation carried by the couple was determined. The NGS technology was used to sequence the variations of HBA1, HBA2 and HBB directly and construct haplotype linkage analysis for preimplantation genetic diagnosis.@*RESULTS@#Direct sequencing and haplotype linkage analysis of HBA1, HBA2 and HBB showed that two of the six blastocysts were α/β complex thalassemia, one was β-thalassemia heterozygote, two were α-thalassemias heterozygotes, and one was intermediate α-thalassemia. A well-developed embryo underwent preimplantation genetic diagnosis was implanted into the mother's uterus, and a healthy infant was born at term.@*CONCLUSION@#Preimplantation genetic diagnosis can be carried out by NGS technology in α/β complex thalassemia couples, and abortion caused by aneuploid embryo selection can be avoided.

RESUMO

OBJECTIVE@#To summarize the experience in the application of muscle relaxants in the perioperative period in neonates with congenital esophageal atresia-tracheoesophageal fistula (EA-TEF).@*METHODS@#A retrospective analysis was performed on the medical data of 58 previously untreated neonates with EA-TEF who were treated in the Neonatal Center of Beijing Children's Hospital, Capital Medical University from 2017 to 2019. The incidence rate of anastomotic leak was compared between the neonates receiving muscle relaxants for different durations after surgery (≤ 5 days and > 5 days). The correlation between the duration of postoperative use of muscle relaxants and the duration of mechanical ventilation was evaluated.@*RESULTS@#Among the 58 neonates with EA-TEF, 44 underwent surgery, among whom 35 with type III EA-TEF underwent thoracoscopic surgery. Among these 35 neonates, 30 (86%) received muscle relaxants after surgery, with a median duration of 4.75 days, and 6 (18%) experienced anastomotic leak. There was no significant difference in the incidence rate of anastomosis leak between the ≤ 5 days and > 5 days groups (@*CONCLUSIONS@#Prolonged use of muscle relaxants after surgery cannot significantly reduce the incidence of anastomotic leak, but can prolong the duration of invasive mechanical ventilation in neonates with EA-TEF. Therefore, prolonged use of muscle relaxants is not recommended after surgery.

RESUMO

BACKGROUND@#The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions. In China, breast masses are divided into four categories according to the treatment method: inflammatory masses, adenosis, benign tumors, and malignant tumors. These categorizations are important for guiding clinical treatment. In this study, we aimed to develop a convolutional neural network (CNN) for classification of these four breast mass types using ultrasound (US) images.@*METHODS@#Taking breast biopsy or pathological examinations as the reference standard, CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers. The patients were randomly divided into training and test groups (n = 1810 vs. n = 1813). Separate models were created for two-dimensional (2D) images only, 2D and color Doppler flow imaging (2D-CDFI), and 2D-CDFI and pulsed wave Doppler (2D-CDFI-PW) images. The performance of these three models was compared using sensitivity, specificity, area under receiver operating characteristic curve (AUC), positive (PPV) and negative predictive values (NPV), positive (LR+) and negative likelihood ratios (LR-), and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators, between images from different hospitals with AUC, and with the performance of 37 radiologists.@*RESULTS@#The accuracies of the 2D, 2D-CDFI, and 2D-CDFI-PW models on the test set were 87.9%, 89.2%, and 88.7%, respectively. The AUCs for classification of benign tumors, malignant tumors, inflammatory masses, and adenosis were 0.90, 0.91, 0.90, and 0.89, respectively (95% confidence intervals [CIs], 0.87-0.91, 0.89-0.92, 0.87-0.91, and 0.86-0.90). The 2D-CDFI model showed better accuracy (89.2%) on the test set than the 2D (87.9%) and 2D-CDFI-PW (88.7%) models. The 2D model showed accuracy of 81.7% on breast masses ≤1 cm and 82.3% on breast masses >1 cm; there was a significant difference between the two groups (P < 0.001). The accuracy of the CNN classifications for the test set (89.2%) was significantly higher than that of all the radiologists (30%).@*CONCLUSIONS@#The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.@*TRIAL REGISTRATION@#Chictr.org, ChiCTR1900021375; http://www.chictr.org.cn/showproj.aspx?proj=33139.

RESUMO

Depression is a mental illness characterized by persistent negative feelings, which has seriously threatened people's health. In recent years, neuronal autophagy, an important stress response, has also been regarded as a hypothesis for the pathogenesis of depression. Relevant studies have shown that either insufficient or excessive autophagy triggers neuronal damage, and activated or inhibited neuronal autophagy can be observed in animal models of depression. Therefore, neuronal autophagy may be a double-edged sword involved in the pathogenesis of depression. It is believed in traditional Chinese medicine (TCM) that the occurrence of this disease is closely related to liver depression and spleen deficiency. Chinese medicine regulates the neuronal autophagy via multiple ways. The TCM monomers that regulate neuron autophagy are capable of protecting nerves or penetrating the blood-brain barrier. TCM compounds designed for soothing liver or invigorating spleen have been proved effective against this disease, demonstrating that the core pathogenesis of depression lies in liver depression and spleen deficiency. The regulatory effects of TCM on neuronal autophagy in depression models might result from its action on multiple targets, multiple pathways, and multiple systems. This paper discussed the limitations in current research based on the involvement of neuronal autophagy in depression and its treatments, in order to provide ideas for later similar research and that concerning TCM treatment of depression.
