A 10 year-old female child developed erythema on the scalp,perioral area,neck,trunk,buttocks,palms and soles within 1 month after birth.Her skin was dry and rough,and the hairs were fine,soft,sparse and easily broken.As age advanced,typical hyperkeratosis and thickening of the skin occurred on an erythematous base.At the age of 5 years,the child developed photophobia and vision impairment.When the child was 8 years old,progressive hearing loss was observed.Physical examination revealed that the height and weight were 109 centimeters and 19 kilograms respectively.Skin examination showed fine,soft,sparse and easily-broken hair,large areas of brown plaques with crusts on the scalp,perioral area,neck,trunk and buttocks,and fissured,purulent and foul-smelling verrucous hyperplasia over these plaques.Brown to black hyperkeratotic plaques were scattered over the extremities,and diffuse hyperkeratosis occurred on the palms and soles.Both fingernails and toenails became thickened,cloudy and white with distal separation and deformation of the nail plate.As ophthalmic examination showed,the patient had photophobia,bilateral bulbar conjunctival hyperemia,corneal opacity and corneal vascular proliferation,and the visual acuity was 0.5 in the left eye and 0.2 in the right eye.Otolaryngological examination revealed moderate binaural sensorineural deafness.Stomatological examination showed enamel hypoplasia and diastema widening.Genetic testing showed a heterozygous mutation (c.C50T) in exon 2 of the gap junction protein beta 2 (GJB2) gene.Based on these clinical manifestations and examinations,the patient was diagnosed with keratitis,ichthyosis,and deafness (KID) syndrome.Skin lesions of the patient were significantly improved after the treatment with oral acitretin.

This study was aimed to set up the fingerprint chromatograms of chemical principles of Dendrobii Caulis by HPLC-DAD-ELSD. This analysis was performed at 30°C on a Dikma Cl8 column (250 mm × 4.6 mm, 5 μm) with a mobile phase consisting of acetonitrile-0.5% glacial acetic acid, gradient elution, at the flow rate of 1.0 mL?min-1 with DAD and ELSD detection. The HPLC fingerprint of Dendrobii Caulis was established. And 9 fingerprint peaks were marked. The similarity among different species was low. This method was stable, reliable and repeatable. It is useful for the study on the relationship between chemical components and species of Dendrobii Cauli.

Abstract To thoroughly implement General Secretary Xi Jinping’s important instructions on preventing and controlling myopia in children, the Ministry of Education together in collaboration with relevant eight departments jointly issued and implemented a plan to tackle and prevent myopia among children and young students. This article focuses on strengthening organizational leadership, optimizing system design, ensuring responsibilities of implerentation, uniting prevention and control efforts, highlighting pilot drive, strengthening demonstration guidance, promoting integration of teaching and medicine, playing the role of experts, insisting on scientific prevention and control, regularly monitoring and early warning, and reducing academic burden. Strengthen physical training, strengthen hardware construction, improve the visual environment, collaborative family-school relationship, comprehensively overcome difficulties, strengthen market supervision, standardize industry behavior, strengthen team building, strengthen professional training, support professional construction, provide intellectual support, increase financial investment, ensure the implementation of funds, strengthen publicity and education, highlight the function of educating people, improve the assessment mechanism, and be accountable according to regulations and laws. This paper summarizes the phased progress made in the comprehensive prevention and control of myopia among children and adolescents in provinces (cities, districts) across China over the past year through the solid implementation of the Plan. A number of phased achievements have been achieved, providing important supports for the construction of a healthy China.

MTA is rarely applied in the repair of root fractured section. A case of maxillary second premolar which fractured ten years ago had been connected with MTA in this article and the cone beam CT was used to evaluate the treatment effect.

Objective: This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs). Materials and Methods: This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables. Results: The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m2 for PA, 75.9 ± 14.3 mL/m2 for EH, and 77.3 ± 12.8 mL/m2 for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m2 for PA, 30.7 ± 8.1 mL/m2 for EH, and 29.5 ± 7.0 mL/m2 for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m2 for PA, 56.9 ± 12.1 g/m2 for EH, and 44.1 ± 8.9 g/m2 for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosteroneto-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1. Conclusion Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.
