A similar expression pattern was also found in the mesenchyme between the deciduous and permanent teeth in human. Our findings demonstrated that the eruption of deciduous tooth released the stress inside mandible, thus induced the "Wnt translocation" from the mesenchyme into the epithelium of permanent counterpart and therefore initiated the development of permanent teeth. The underlying mechanism of the replacement of deciduous teeth by permanent teeth is the regulation of biomechanical stress throughout the initiation process. Based on the findings, we proposed the theory of "biomechanical stress regulation of the tooth replacement" . The replacement pattern and regulatory mechanism provide a scientific foundation for the organ development and regeneration by regulating the biomechanical stress and Wnt pathway in the future.The pandemic of COVID-19 in early 2020 is a big challenge to the mechanism of major epidemic prevention and control, the national public health management system, as well as medical and health resources in China. Going through the COVID-19 crisis, we should fully understand the problems and vulnerabilities of the current public health system in China, and it is imperative to deepen and strengthen the public health system which should be throughout whole life cycle and whole process. Oral cavity is the first portal of human body, while illness finds its way in by the mouth. Oral health is highly related to general health and quality of life. The outbreak has drawn the public's attention to the public health system. The establishment and improvement of the oral public health system with the concept of "public health with Chinese characteristics" should also attract people's attentions and thoughts. RI-1 datasheet Furthermore it is urgent to recognize the importance of oral public health.Objective To analyze the clinical features and the results of the whole exome sequencing (WES) of a Chinese family containing both pulmonary sarcoidosis patients and healthy members, and to find potent genes and variants that may be involved in the pathogenesis of sarcoidosis. Methods Three patients with pulmonary sarcoidosis and 1 healthy member was included from a Chinese Han family in the north of China diagnosed in November 2016, which characterized as 2 consecutive generations including 2 males and 1 female, aged from 23 to 69 years old. The proband is Ⅱ-6. Pulmonary sarcoidosis was diagnosed by clinical features, imaging and pathological findings, and clinical data such as family history were collected. Whole blood samples were taken and WES (Illumina NovaSeq S2) was performed. The pathogenicity analysis and gene annotation analysis were performed by ExAC, SIFT, Polyphenv2, Metascape databases. Results It was found that 27 genes were highly pathogenic in the database filtering result. After gene annotation analysis, we found that ZC3H12A gene can negatively regulate the differentiation of Th17 cells, which may be involved in the onset of pulmonary sarcoidosis. Sanger sequencing confirmed the c.1361 A>G variant in 3 sarcoidosis patients but normal in healthy member. Conclusions In patients with familial pulmonary sarcoidosis, the genetic background could regulate immune response which is one of the pathogenic mechanisms of sarcoidosis. The whole exome test and gene ontology analysis showed that Ⅱ-2, Ⅱ-6 and Ⅲ-1 pulmonary sarcoidosis patients in this family were all shared the same variant on ZC3H12A gene, which played a pivotal role in differentiation of Th17 cells and is a potent pathogenesis gene in this Chinese pulmonary sarcoidosis family.Objective To explore the end criteria of forced vital capacity(FVC) curve in adults. Methods A multicenter cross-sectional study was performed in Zhongshan Hospital Affiliated to Fudan University, the First Affiliated Hospital of Fujian Medical University, and the Third Affiliated Hospital of Inner Mongolia Medical University from January 2017 to August 2017. A consecutive sample of subjects who completed the spirometry test and FVC curves met end criteria of no volume change ( less then 0.025 L) for ≥ 1 s were qualified in this study. Subjects were divided into a normal group (n=610), an obstructive group (n=536), and a restrictive group(n=306) according to pulmonary function test results. The FET values in different groups were compared. The side effects in the 3 groups and the diagnostic accuracy, specificity and security of different FET in the obstructive group were assessed. Results The FET values of the normal group, the obstructive group, and the restricted group were (4.00±1.07) s, (8.08±1.56) s and For patients with normal lung function or restrictive lung function defect, exhalation platform should be used as the end of exhalation standard. For patients with obstructive lung function defect, an FET of up to 7 s is appropriate.Objective To investigate the clinical manifestations of the clinical characteristics of 141 patients with coronavirus disease 2019 (COVID-19) and the imaging evolution characteristics of High Resolution CT (HRCT) in the chest. Methods From January 20, 2020 to February 8, 141 COVID-19 patients in Renmin Hospital of Wuhan University, 77 males and 64 females, with a median age of 49 (9,87) , were retrospectively analyzed. The clinical features, laboratory examination indexes and HRCT evolution findings of 141 COVID-19 patients were analyzed. Results Laboratory examinations of 141 COVID-19 patients showed a decrease in white blood cell count and lymphocyte ratio. Among the 141 patients with COVID-19, fever (>37.5 ℃) was the most common clinical manifestation in 139 cases (98.58%) , and occasionally non-respiratory symptoms such as diarrhea in 4 cases (2.84%) . 141 patients with COVID-19 had abnormal HRCT. 52 (36.88%) chest HRCT images showed ground-glass opacity (GGO) , mainly under pleural; 23 (16.31%) GGO with , and assistance in clinical typing and post-treatment follow-up.In December 2019, a novel coronavirus was identified in Wuhan City, Hubei Province, China and later the disease was named coronavirus disease 2019 (COVID-19) . On March 11, 2020, the World Health Organization (WHO) officially announced that COVID-19 had reached global pandemic status. This article summarized the understanding of the etiology, pathogenesis, epidemiology, clinical characteristics, diagnosis, treatment, rehabilitation, and prevention and control measures of COVID-19 based on the available data and anti-epidemic experience in China.
