Because preterm infants are premature,the rates of refractive errors and visual abnormalities are significantly higher than those normal full-term infants.By understanding their refractive characteristics and the factors those affect visual development,meanwhile,recognizing that premature birth also plays a role in the refractive or visual development of preterm infants without retinopathy of prematurity (ROP),we can establish the strict follow-up system,then early detection and be early in time for premature children with clinical intervention or treatment which is beneficial for normal visual development.It is extremely important to reduce abnormal visual development in preterm children,and to improve the visual quality of patients and quality of life.This paper summarizes the researches of refractive and visual development in preterm infants.

Objective: To investigate the impact of clopidogrel or aspirin resistance on major adverse cardiovascular events (MACE) in elderly patients with acute coronary syndrome (ACS) and to explore the application value of thromboelastogram (TEG) in antiplatelet therapy. Methods: A total of 177 ACS patients admitted in our hospital from 2012-09 to 2014-12 were enrolled. The patients were at the mean age of (70.4±10.7) years, all of them received TEG and coagulation function test. Based on the reaction of antiplatelet therapy, they were divided into 2 groups: Non-resistance group,n=98 and Resistance group,n=70, which was further divided into 2 subgroups as Maintenance dose subgroup,n=39 and Increased dose subgroup,n=40. The patients were followed-up for 3 months to observe MACE occurrence including cardiovascular death, angina recurrence, ischemic stroke, myocardial infarction, acute thrombosis and hemorrhage. Results: In Resistance group, there were 50/79 (63.3%) patients with aspirin resistance and 29 (36.7%) with clopidogrel resistance. Compared with Non-resistance group, Resistance group showed decreased coagulation time, clot formation time, TEG reducing rate after 30 minutes maximum amplitude (LY30), activated partial thrombin time (APTT), thrombin time (TT) and international normalized ratio (INR), allP<0.05; while increased levels angle, maximum amplitude of TEG, coagulationindex, ifbrinogen and D-dimer, allP<0.05. Compared with Non-resistance group, Resistance group had the higher MACE rate 21.5% vs 7.1%,P<0.05; in addition, Increased dose subgroup had the lower MACE rate than Maintenance dose subgroup 17.5 vs 25.6%,P<0.05. Conclusion: Clopidogrel or aspirin resistance had the higher incidence of MACE in elder ACS patients; TEG was helpful for guiding antiplatelet therapy and reducing MACE incidence.

Objective To compare the effectiveness of the three operation mode in treatment of ovarian cyst. Methods According to the digital table,138 patients with ovarian cyst were divided into three groups,the group A (n=46 cases)were operated through open operation,group B (n =46 cases)were operated through transvaginal operation,group C(n=46 cases)were operated through laparoscopic operation.The three groups were observed the situation of operation (operation time,bleeding volume,the first exhaust time,hospitalizationtime ),complications (infection,hemorrhage,perimenopausal changes ),postoperative follow -up for 1 years.The recurrence rate was observed.Results Group A of 46 patients were successfully completed surgery,B,C groups of 1 patients was con-versed to laparotomy due to severe adhesion.B,C groups in the operation time,amount of bleeding during the opera-tion,the time of hospitalization were significantly less than that of group A (t=4.306,5.172,3.012,3.926,3.776, 2.168,P<0.05,P<0.01).B group was significantly less than those of A,C group in the first exhaust time (t=3.014,2.446,all P<0.05).In the operation time of group B was obviously less than that of group C (t=2.748,P<0.05).A,B,C three groups of postoperative complication rates were 39.1%,11.1%,15.6% respectively;the incidence of complications of B,C groups was lower than that in A group (χ2 =9.82,8.64,all P<0.01 ).After 1years follow-up,the recurrence rate in group B was significantly higher than that of A and C groups (χ2 =6.72, 6.72,all P<0.01).Conclusion Treatment of ovarian cyst vaginal surgery and laparoscopic surgery wound is small, but the person that weigh should be performed open adhesion treatment,individualized treatment.

[Abstract ] Objective As an important metal element, iron is involved in a variety of life activities.This study was to inves-tigate the effect of iron deposition on the apoptosis of PC12 cells and the expression of glyceraldehyde de-3-phosphate dehydrogenase (GAPDH). Methods PC12 cells were incubated with FeCl3 at 50, 100, and 500 μmol/L for the establishment of an iron deposi-tion cell model.The proliferation of the PC12 cells was measured with the CCK-8 method, their apoptosis determined by TUNEL, the expressions of GAPDH mRNA and protein detected by quantitative real-time PCR and Western blot respectively, and the level of GAP-DH in the nuclei measured by immunofluorescence assay. Results Compared with the normal control group, the proliferation rate of the PC12 cells was decreased in the 50μmol/L FeCl3 group (100%vs [77.13 ±3.9]%, P>0.05) and significantly in the 100 and 500 μmol/L groups ([66.19 ±3.37]% and [13.84 ±0.43]%) (P<0.05).In comparison with the control, the expression of GAPDH mRNA was up-regulated in the 50 μmol group (1.00 ±0.00 vs 1.42 ±0.03, P>0.05) and remarkably in the 100 and 500μmol/L groups (1.93 ±0.07 and 2.33 ±0.15) (P<0.05), while that of GAPDH protein down-regulated in the 50μmol group (1.00 ± 0.00 vs 0.94 ±0.11, P>0.05) and markedly elevated in the 100 and 500 μmol/L groups ( 1.45 ±0.13 and 1.79 ±0.07 ) ( P<0.05) .After iron deposition, GAPDH transferred from the cytoplasm to the nuclei of the PC12 cells and nuclear accumulation was observed. Conclusion Iron deposition increases the apoptosis of PC12 cells, which may be related to the up-regulated expression of GAPDH in the nuclei.

Objective To study the clinical efficacy of combination of Modified Lianpo Decoction and standard quadruple therapy for Hp-related gastritis of damp-heat syndrome of spleen and stomach. Methods Based on the principles of random, contrast, and double-blind, 118 cases of Hp-related gastritis of damp-heat syndrome of spleen and stomach were randomly divided into western medicine group (39 cases) and combined Chinese and western medicine group (79 cases). The western medicine group was treated with standard quadruple therapy (PPI + bismuth + two kinds of antibiotics), and the combined Chinese and western medicine group with Modified Lianpo Decoction additionally for two weeks. The clinical efficacy, TCM symptom scores, and eradication rate of Hp were observed by electronic gastroscope, rapid urease test, and pathologic examination before and one month after the treatment, respectively. Results The clinical effective rate of the western medicine group was 76.9% (30/39), while that of the combined Chinese and western medicine group was 94.9%(75/79), with statistical significance (P<0.05). The Hp eradication rate of the western medicine group was 87.2%(34/39), and that of the combined Chinese and western medicine group was 97.5% (77/79), with statistical significance (P<0.05). TCM symptom scores regarding damp-heat syndrome of the spleen and stomach of the combined Chinese and western medicine group were significantly better than those of the western medicine group (P<0.05). Conclusion The clinical efficacy, TCM symptoms, and eradication rate of Hp can be significantly improved by combination of Modified Lianpo Decoction and standard quadruple therapy in the treatment for patients with Hp-related gastritis of damp-heat syndrome of spleen and stomach.
