Objective:To explore the application of optical coherence tomography (OCT) in the interventional diagnosis and treatment of intermediate coronary disease.Methods:Patients were enrolled during January 2017 to January 2019, in the Department of Cardiology, the Ninth People's Hospital Affiliated to Shanghai Jiaotong University School of Medicine.The patient whose diagnosis was confirmed as intermediate coronary artery lesion by coronary angiography then underwent coronary OCT examination.The general information, disease history, drug use, biochemical indicators and OCT imaging indicators were collected.Results:(1)A total of 75 borderline lesions were detected in 69 patients with coronary heart disease, including 52 cases of left anterior descending artery (LAD) (75.4%), 4 cases of left circumflex artery (5.8%, 4/69), and 19 cases (27.5%, 19/69) of right coronary artery (RCA). (2) According to the analysis of the plaque characteristics of borderline lesions OCT, 7 cases were accompanied with thrombosis, 6 cases with plaque rupture, 25 cases with thin fiber cap lipid plaque, 49 cases with macrophages, 35 cases with microvascular, 35 cases with cholesterol crystallization, 3 cases with ulcer and 6 cases with intimal dissection.(3)The median of the minimum lumen area (MLA) determined by OCT was 2.9 mm 2.In the MLA<2.9 mm 2 group, C-reactive protein (CRP) ((2.92±2.44) mg/L vs.(1.98±1.30) mg/L, P=0.045), total cholesterol (TC) ((4.13±0.78) mmol/L vs.(3.74±0.75) mmol/L, P=0.041), low density lipoprotein cholesterol ((2.77±0.83) mmol/L vs.(2.22±0.78) mmol/L, P=0.007), small and dense LDL ((1.02±0.44) mmol/L vs.(0.80±0.34) mmol/L, P=0.024), lipoprotein a ((1.16±0.17) mg/L vs.(0.95±0.09) mg/L, P=0.042) were significantly higher than those in MLA≥2.9 mm 2 group.(4). According to the interventional strategy, patients were divided into two groups: percutaneous coronary intervention (PCI) group (N=16) and non-PCI group (N=59). The area stenosis (AS%) ((68.58±4.90)% vs.(63.10±7.09)%, P=0.001), diameter stenosis (DS%) ((65.65±6.91)% vs.(60.77±8.41)%, P=0.024), lipid plaque curvature ((245.3±41.0)° vs.(189.8±99.6)°, P=0.001), lipid plaque length ((19.11±6.40) mm vs.(14.72±9.30) mm, P=0.035) were deteriorated significantly in the PCI group than those in non-PCI group, the differences were all of them were statistically significant.(5)The incidence of 1-year major cardiovascular adverse events (MACE) was 6.25% in Oct guided PCI group and 5.08% in patients without PCI.There was no significant difference between the two groups ( P=0.317). Conclusion:According to the OCT assessment in the intermediate coronary lesions, it is found that the smaller the luminal area, the higher the serum LDL cholesterol level.More Interventional therapy were performed in the vulnerable plaques with large lipid cores.Decision-making for intermediate lesion was highly depended on the plaque tissue characteristics, rather than just MLA size.

ABSTRACT
The review aims to assess the effectiveness and safety Pudilan Xiaoyan oral liquid in treating pediatric suppurative tonsillitis systematically through searching relevant electronic database and collecting relevant literature. Meta-analysis was performed with the RevMan 5.3 software. Eighteen RCTs of 1 883 patients of pediatric suppurative tonsillitis were included. Meta-analysis showed that： compared with the application of antibiotics alone, combined with Pudilan can effectively improve the treatment of pediatric suppurative tonsillitis in efficacy rate and shorten the time of recovering normal temperature, the time of tonsil purulent discharge and can also reduce the extinction time of sore throat, antiadoncus or congestion subsided and appetite recovery. There was no severe adverse reaction during the treatment. Compared with the application of antibiotics alone, combined with Pudilan may be more effective and safe in the treatment of pediatric suppurative tonsillitis, which can not be strongly proved at present for lack of studies with high quality.
ABSTRACT
This article reports a rare case of bilateral choroidal occlusion that occurred in a 24-year-old woman with antiphospholipid syndrome (APS) associated with systemic lupus erythematosus (SLE). This young lady concurred with aorta ventralis thrombosis and bilateral iliac artery occlusion when presented, and experienced a rapid deterioration of vision. She also has a history of recurrent miscarriage. Corticosteroid, immunosuppression and anticoagulation therapy were administered. Patients with APS associated with SLE are at risk for thrombotic phenomena, which may affect the ocular vessels of all sizes, including choroidal vessel. Our case alerts ophthalmologists and rheumatologists that bilateral choroidal occlusion may indeed be developed in patients with APS associated with SLE, and is a potential cause of visual morbidity.

ABSTRACT
Objective To analyse the retrobulbar haemodynamic changes after vitrectomy in patients with rhegmatogenous retinal detachment (RRD). Methods Color Doppler flow imaging (CDFI) was used for measurement of blood flow velocities including peak systolic velocity (PSV), end diastolic velocity (EVD) and resistive indexes (RI) of the ophthalmic artery (OA), posterior ciliary arteries (sPCA) and central retinal artery (CRA) in 50 eyes of 50 patients with RRD. In them 22 eyes were filled with silicone oil, 28 eyes were filled with 12%C3F8 and 22 eyes were operated to remove silicone oil after filled with silicone oil for 2-4 months, and then CDFI parameters were obtained. The contralateral eyes were used as control eyes before and after the operation. Results There were no significant differences in CRA and sPCA, and PSV, EDV and RI before treatment between RD and OA eyes and control eyes (P>0.05). PSV and EVD of CRA were significantly increased 3 months after surgery, RI were decreased significantly (P<0.05). There were no significant differences in blood flow parameters of OA and sPCA before and after surgeries (P>0.05). No changes were found in control eyes 3 months after surgery. Conclusion VRS might increase the velocity of CRA, decrease RI and improve ocular blood supply postoperatively.

ABSTRACT
Objectives Aiming at the current health management mode of chronic disease preven-tion and control as the focus of work, this paper was to evaluate the effect of chronic disease management-based education on clinical teaching and training in cardiovascular medicine. Methods Totally 54 students participating in internship training in Department of Cardiology, the Shanghai Ninth People’s Hospital be-tween July 2013 and Aug 2014 were enrolled. Twenty-eight students were taught by chronic disease man-agement-based method while twenty-six students were taught by traditional method. After the internship training in cardiology, final examination (theoretical exam, skill appraisal and case analysis) were compared between the two groups to assess the teaching efficacy. Questionnaire survey was employed to investigate student satisfaction with chronic disease management-based teaching method. Data were analyzed by SPSS 13.0 software. Quantitative data or enumeration data between two groups were compared by t-test or chi-square test respectively. Results There was no significant difference in the theoretical exam score between two groups (P=0.422). However, the scores of skill appraisal and case analysis in students taught by chronic disease management-based method were significantly higher than those in students taught by traditional method (P<0.05). Most students taught by chronic disease management-based method were satisfied with the novel teaching method. Conclusion In the course of clinical medicine education, the emphasis on the management of chronic diseases can not only significantly improve the quality of clinical teaching in car-diovascular medicine, but also lay the foundation for the implementation of the concept of chronic disease management.
ABSTRACT
BackgroundDry eye is a multi-factorial-induced tear film and ocular surface disorder.Immunoinflammation plays a key role in the pathogenesis of dry eye.As inhibitor of the cyclo-oxygenase pathway,nonsteroidal anti-inflammatory drugs play an anti-inflammatory and anti-hypersensitivity role,and it can be a potential treatment for dry eyes.ObjectiveThis study was to investigate the effectiveness of nonsteroidal anti-inflammatory drugs (0.1％topical pranoprofen) on moderate to severe dry eyes and its mechanism.MethodsThis was a small sample of randomized controlled clinical trial.Thirty right eyes of 30 patients with moderate to severe dry eyes were included in the study according to the diagnosis criteria and randomized into two groups.The patients of the trial group received topical administration of 0.1％ pranoprofen plus 0.1％ sodium hyaluronate,and those of the control group received the topical 0.1％ sodium hyaluronate only.Ocular surface inflammation index scores (OSDI) and ocular surface fluorescine staining (OSS) scores were measured under the slit lamp,and tear film break-up time (BUT),Schirmer Ⅰ test values were evaluated.The expression of human leucocyte antigen-DR (HLA-DR) and CD11b in conjunctiva epithelial cells were detected by impression cytology and flow cytometry (FCM).All the indexes were compared between the two groups before and after treatment.Informed consent was obtained from all patients.ResultsThere were no significant differences in terms of age and gender and their baseline values between the trial group and control group (t=0.412,P=0.684;x2=0.240,P=0.624),and so were all the indexes (P＞0.05).Compared with the control group,the OSDI,OSS scores and cells positive for HLA-DR were lowered but the BUT was delayed in the trial group on day 15 ( t=2.43,P=0.03;t=2.83,P=0.01;t=3.29,P=0.00;t=3.23,P=0.00 ).No significant differences were found in the Schirmer Ⅰ test value and CD11b expression between these two groups (t=0.17,P=0.87;t=0.28,P=0.79).The OSDI,OSS scores and BUT were significantly improved,and the number of cells positive for HLA-DR were reduced 15 days after administration of drugs in comparison with before treatment in the trial group ( t =12.30,10.70,6.10,7.92,P =0.00 ).However,there were no comparable alteration seen in these indexes before and after the usage of drugs in the control group ( P＞0.05).Positive correlations were found in HLADR expression with OSDI and OSS ( r =0.601,P =0.018 ; r =0.586,P =0.022 ) and a negative correlation in HLADR expression with BUT (r=-0.697,P=0.004) on day 15 in the trial group.ConclusionsTopical usage of 0.1％ pranoprofen is beneficial for remitting the ocular signs and symptoms in moderate to severe dry eyes.This study illustrates that topical usage of 0.1％ pranoprofen can down-regulate the expression of inflammatory markers in conjunctival epithelial cells.
ABSTRACT
Background It has been clarified that topical administration of cholinomimetic drug or prostaglandin analogus can effectively low intraoeular pressure (IOP) in primary angle-closure glaueoma and angleopen glaucoma,respectively.The two eyedrops are often combined clinically to treat glaueomatous eye.But their effect mechanism on ciliary muscle is different.It is neeessarv to prove the clinical efficacy of combination of these two drugs.Objective This study attempted to compare hypotensive effect of individual and combinative use of 2％piloearpine and 0.004％ travoprost in normal rabbit eyes.Methods Thirty normal albino rabbits were randomly divided into three parallel groups.Lateral eye of each rabbit was appointed as the experimental eye and the fellow eye was used as control eye.2％ Pilocarpine eyedrop was instilled three times daily and 0.004％ travoprost eyedrops was used once per night in the pilocarpine and travoprost group.These two drugs were combined in the combination group.The normal saline solution was used in the control eyes IOP was measured bilaterally with Perkins application tonometer at 8:00 am on the day before and 1,2,4,8,14,24 days after the administration of eyedrops.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The IOP was significantly lower on 1 day after use of eyedrops than baseline IOP in the experimental eyes in the pilocarpine group,travoprost group and combination group,but no obvious change in IOP before and after use of eyedrops in the control eyes.There was no significant difference in the baseline IOP in both experimental eyes and control eyes,however,signifieant differences were seen in various time points after administration of eyedrops between experimental eyes and control eyes(P＜0.05).Compared with baseline IOP,IOP declined by 17.5％-22.0％ in pilocarpine group,23.8％-26.4％ travoprost group,27.6％-32.0％ in the combination group.For normal eye,piloearpine+travoprost showed a more power lowing IOP effect.Conclusions Hypotensive effect of combinative use of 2％ pilcoarpine and 0.004％ travoprost is strongest in comparison with individual use of pilocarpine or travoprost,but less than the statistical sum of individual use of these two drugs in a 24-day duration in normal eye of albino rabbit.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the predictive factors of refractory glaucoma treated with diode laser transscleral cyclophotocoagulation (TSCP) in a midterm observation.</p><p><b>METHODS</b>Fifty-four consecutive patients (54 eyes) with refractory glaucoma were enrolled and underwent TSCP (power of 1.5-2.0 W, exposure time of 2 seconds and 20-50 applications). Patients were regularly followed up for 12 months. Intraocular pressure (IOP) was measured before TSCP treatment and at each follow-up visit. Patients were divided into the sensitive and insensitive groups according to the effect of a single treatment of TSCP on IOP. The success rate was defined as the percentage of eyes achieving an IOP between 5 and 21 mm Hg following TSCP therapy at their final follow up visit. Difference of age between the sensitive and insensitive groups was evaluated with independent-samples T test and that of gender distribution of two groups was evaluated with Fisher's exact test. The success rate of different types of glaucoma to TSCP was calculated.</p><p><b>RESULTS</b>A total of 32 patients were sensitive to TSCP (sensitive group) and 22 patients were insensitive to TSCP (insensitive group). The success rates of female (77.8%, 14/18) and cases being over 50 years (71.4%, 20/28) were higher than those of male (50.0%, 18/36) and ones being under 50 years (46.2%, 12/26) (all P>0.05). The age of the sensitive and insensitive groups was 56.0+/-15.5 and 46.4+/-15.4 years, respectively (P=0.029). The age (P=0.029) and gender distribution (P=0.046) of the two groups had significant difference. The success rate of neovascular glaucoma, primary angle-closure glaucoma, primary open angle glaucoma, traumatic glaucoma, uveitic glaucoma, and secondary glaucoma after silicone oil injection to TSCP was 57.1%, 100.0%, 50.0%, 20.0%, 81.8%, and 0%, respectively.</p><p><b>CONCLUSION</b>Age, gender, and type of glaucoma appear to be associated with effect of TSCP on IOP control.</p>
