To report the thickness of the peripapillary retinal nerve fibre layer (pRNFL) in Chinese children and examine its association with refractive error, axial length (AL) and optic disc parameters.Population-based cross-sectional study.A total of 2893 seven-year-old children from 11 randomly selected primary schools in Anyang, central China.Participants underwent ophthalmic examinations including optical biometry, cycloplegic autorefraction and spectral-domain ocular coherence tomography.Retinal nerve fibre layer thickness in 16 radial sections, cycloplegic spherical equivalent, AL.The mean (SD) average RNFL thickness was 102.01(8.02) µm. The average RNFL thickness decreased with smaller disc area (r = 0.18, RRetinal nerve fibre layer thickness decreased with increasing AL, higher myopia, bigger cup area, smaller disc and rim area, and a smaller nerve head volume, but the coefficient of determination for all these associations was small. The RNFL in myopes was significantly thinner than emmetropes or hyperopes, but with small absolute differences. The study provides RNFL values for healthy 7-year-old Chinese children. Follow up of this cohort to observe the change of RNFL thickness with myopia and possible change in detected associations with age is planned.

To understand the status of coxsackievirus B (CVB) infection in senior subjects and explore the association of the infection with cardiovascular diseases.By means of ELISA and RT-PCR, CVB IgG antibody and nucleic acid were detected in 172 patients with cardiopathy and 58 control subjects.The positivity rate of CVB IgG antibody was 43.61% (75/172) in the patient group and 15.52% (9/58) in the control group, showing obvious difference between the two groups. CVB RNA tests revealed a CVB RNA-positivity rate of 20.93% (36/172) in the former group and 3.45% (2/58) in the latter, with also a significant difference (P0.01).CVB infection is prevalent in aged patients with heart disease, which should be given due attention to.

To understand the state of Chlamydia pneumoniae (Cpn) infection in patients with coronary heart disease (CHD), and explore the relationship between Cpn infection and the gonesis and progressin of CHD.By adopting sandwich method with double antibodies and indirect ELISA method, we detected serum Cpn immune complex and IgG antibody in 160 CHD patients (confirmed by coronary artery angiography) and 40 subjects without CHD.The positivity rate of Cpn IgG type immune complex in the CHD group (63.8%) was significantly higher than that in the control group (40.0%, P0.05), similar to the results of Cpn IgG antibody detection (65.0% vs 32.5%, P0.05).Cpn infection is closely connected with the CHD, but their exact relationship needs further exploration and study.

Background Pseudoachalasia is a rare disorder whose presentation strongly resembles idiopathic achalasia. Case presentation Here, we present a case of a 42-year-old female patient with esophageal leiomyoma who was initially diagnosed with achalasia. On endoscopical investigation, however, it became apparent that she had pseudoachalasia as consequence of a leiomyoma at the esophagogastric junction (EGJ). The condition was successfully treated through submucosal tunneling endoscopic resection. Conclusion This case suggests that submucosal tunneling endoscopic resection is a therapeutic u option for the treatment of pseudoachalasia caused by leiomyoma of EGJ.
