Objective To research the clinical evaluation of potassium dehydroandrograpolide succinate injection in the treatment of COPD combined with CAP and its influence on plasma IL-33, PCT and hs-CRP levels.Method 91 patients with COPD combined with CAP in our hospital from April 2015 to August 2016 were selected and divided into the observation group (48 cases) and the control group (43 cases).The control group was given routine treatment, the observation group was given on the basis of the above treatment of potassium dehydroandrograpolide succinate injection.The clinical efficacy and plasma IL-33, PCT and hs-CRP levels were compared between the two groups after treatment.Results Before treatment, the IL-33, PCT, hs-CRP of two groups of patients had no significant difference.After treatment, the total effective rate of the observation group was 91.67% higher than that of the control group 74.42%, the difference was statistically significant (P<0.05).All the clinical symptoms time of the observation group was significantly lower than that of the control group, and the clearance rate of the observation group (85.42%) was significantly higher than that of the control group (67.44%), the difference was statistically significant (P<0.05), the indexes of the two groups of patients were decreased, the indexes of the observation group significantly lower than that in control group, the difference was statistically significant (P<0.05).There was no significant difference in the incidence of adverse reactions between the observation group and the control group .Conclusion Potassium dehydroandrograpolide succinate injection can significantly improve their plasma IL-33, PCT and hs-CRP levels, the respiratory pathogen and inflammatory mediators are effectively removed, and has good clinical effect, and no serious adverse reactions during treatment.

Objective:To evaluate the effectiveness and safety of transepithelial photorefractive keratectomy (TransPRK) assisted by smart pluse technology (SPT) for the correction of high myopia.Methods:An observational case series study was conducted.Sixty high myopic patients (107 eyes) with spherical equivalent (SE)≥-6.0 D who received TransPRK assisted by SPT from January to December 2016 in Eye Hospital of Wenzhou Medical University were enrolled.Uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) of the patients were examined and recorded in logarithm of the minimum angle of resolution (LogMAR) units, and refraction was examined with a subjective refractometer.The healing of corneal epithelium and corneal haze was observed with a slit lamp.Intraocular pressure (IOP) was measured with the non-contact tonometer.Safety index (SI) and efficacy index (EI) were analyzed.The follow-up time was 12 months.This study protocol adhered to the Declaration of Helsinki and was approved by an Ethics Committee of Eye Hospital of Wenzhou Medical University (No.2019-197-k-177). Written informed consent was obtained from each patient prior to any medical examination.Results:The mean epithelial healing time was (3.77±1.02) days.There were statistically significant differences in UCVA and BCVA between before and after surgery ( Z=380.812, 267.313; both at P<0.001). And the 7-day, 6-month, and 12-month postoperative BCVA were better than preoperative BCVA, showing statistically significant differences (all at P<0.05). Mean SI was 1.10±0.12, and mean EI was 1.05±0.17 at 12 months after surgery.There was no significant difference between the attempted SE before surgery (-8.02±1.36)D and the achieved SE at 12 months after surgery (-8.04±1.51)D ( P=0.523). SE in the predictive range within ±0.50 D accounted for 79% (85/107) and that within ±1.0 D accounted for 92% (98/107). The IOP was slightly increased in 3 eyes at 7 days and 7 eyes at 1 month after surgery, respectively, which returned to normal after the use of ophthalmic solution for lowing IOP.The incidence of haze severer than grade 1 was less than 1% (1 eye), and haze gradually disappeared after application of drugs. Conclusions:TransPRK assisted by SPT for high myopia shows good safety, effectiveness and predictability.It is an ideal corneal surface surgery to correct high myopia.

Objective To investigate the influencing factors and clinical significance of high-resolution magnetic renounce imaging (HR-MRI) plaque enhancement in patients with symptomatic intracranial atherosclerotic (ICAS) stenosis.Methods Patients with symptomatic ICAS stenosis confirmed by digital subtraction angiography and examined by HR-MRI were enrolled prospectively.The demographic data,vascular risk factors,laboratory tests,and imaging features of plaques were compared according to whether the plaques were enhanced or not.They were randomly divided into an ischemic stroke group and a transient ischemic attack (TIA) group according to the results of diffusion-weighted imaging.The relationship between plaque enhancement and ischemic stroke was analyzed.Results Thirty-fiwe patients with symptomatic ICAS stenosis were enrolled.Their mean age was 53 ± 13 years and 25 were males.There were 21 patientswith ischemic stroke and 14 patients with TIA;22 had plaque enhancement and 13 did not have.The leukocyte count ([7.50±2.30] × 109/L vs.[5.80± 1.00] × 109/L;t=2.487,P=0.018) and proportion of severe stenosis (86.4％ vs.53.8％;P =0.040) of the plaque enhancement group were significantly higher than those of the non-enhancement group.The proportion of smoking was significantly lower than the non-enhancement group (13.6％ vs.46.2％;P=0.050).The plaque enhancement rate of the ischemic stroke group was higher than that of the TIA group (71.4％ vs.50.0％;P =0.288),but there was no significant difference.Conclusions In patients with symptomatic ICAS,the degree of vascular stenosis and the leukocyte level were associated with plaque enhancement.In addition,there was no significant correlation between plaque enhancement and the occurrence of ischemic stroke in patients with symptomatic ICAS.
