ABSTRACT:Objective To investigate the effect of PDCA nursing model in children with mycoplasma pneumonia.Methods 120 children with mycoplasma pneumonia treated with Tanre-qing combined with azithromycin were randomly divided into the observation group (PDCA nursing model)and the control group (usual care)with 60 cases in each group.Clinical compliance,effica-cy,clinical symptoms,hospitalization time and adverse reactions were compared in two groups.Re-sults The clinical compliance in the observation group was higher than that in the control group(P<0.05).The effective rate in the observation group was 98.33%,which was significantly higher than that in the control group(88.33%)(P <0.05).Cooling time observation group,cough time, rales disappeared time,tonsils congestion disappear time and length of hospital stay in the observa-tion group were significantly less than those in the control group (P <0.05).Incidence of adverse reactions in the observation group was 15.00%,which was significantly lower than that in the con-trol group(31.67%)(P <0.05).Conclusion PDCA nursing model significantly improves compli-ance and clinical efficacy in children with mycoplasma pneumonia,and shortens the time of clinical symptoms and hospitalization and reduces adverse side effects.

This paper takes the teaching of pathogeny biology and clinical laboratory diagnostics for postgraduates in Shandong Second Medical University as examples. By constructing innovative thinking in scientific research, training research innovation skills, and establishing modular, multi-evaluation systems, a comprehensive training mode for scientific research and innovation ability of medical academic postgraduate students had been proposed, and the implementation and effects of this training mode were thoroughly explored. This mode is expected to bring a positive impact on the training of medical postgraduate students and improve their scientific research and innovation ability, thereby promoting the cultivation of more medical talents with a high degree of scientific research and innovation ability.

Objective:To observe the characteristics of macular telangiectasia (MacTel) in multi-color and multi-mode fundus images.Methods:An abservational case series study was conducted.Sixteen eyes of 12 patients diagnosed with MacTel by fluorescein fundus angiography (FFA) from January to November 2019 in Shandong Eye Hospital were analyzed.There were 8 cases (8 eyes) with MacTel type Ⅰ, among which 4 cases were male and 4 cases were female, with an average age of (62.3±12.5) years.The other 4 cases (8 eyes) had MacTel type Ⅱ, all of which were female, with an average age of (58.7±10.5) years.Best corrected visual acuity, slit lamp microscopy, color fundus photography, multicolor scanning laser imaging, FFA, optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) were carried out in all the patients.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Shandong Eye Institute (No.2019S003).Results:In color fundus images of MacTel type Ⅰ eyes, annular macular exudation with macular edema occurred in 6 eyes, macular edema without hard exudates in 1 eye, and hard macular exudates without macular edema in 1 eye.However, the transparency of retina in temporal fovea in MacTel type Ⅱ eyes decreased, showing a gray color.In multi-color fundus images of MacTel type Ⅰ eyes, punctate granular yellow macular exudation and yellow-green macular edema were observed, which were clearer than those in color fundus images.Punctate exudation was seen in both the blue and green reflectance images, which was clearest in green reflectance image, followed by blue reflectance image and then the infrared reflectance image.In OCT images of MacTel type Ⅰ eyes, cystoid edema of inner retina or uneven reflection signal of outer plexiform retina were observed.Loss of inner and outer retinal structures and cavities were observable in MacTel type Ⅱ eyes, and outer retinal atrophy appeared in 2 eyes.In OCTA images, the destruction of superficial and deep capillary plexus in macular area were observed in both MacTel typeⅠand type Ⅱ eyes, and the destruction of deep capillary plexus was more obvious.In addition, more obviously increased vascular space, decreased vessel density, and increased foveal avascular zone were found in MacTel type Ⅱ eyes.In early stage of FFA, delayed capillary filling near fovea was seen in MacTel typeⅠeyes, and dilated temporal vessels in fovea, some of which showed tumor-like dilation, and the limited tumor-like dilation was enhanced in the later stage.Different degrees of dilated parafoveal blood vessels in the early stage, and the capillary in the temporal side of the macula showing diffuse strong fluorescence in the late stage of FFA was observed in MacTel type Ⅱ eyes.Conclusions:Multi-color scanning laser imaging can be used to observe the morphological characteristics of MacTel, and the imaging features of different types of MacTel are significantly different.
