International Eye Science 2017;17(8):1576-1579
AIM: To investigate the infection factors,diagnosis and treatment of endophthalmitis after intraocular foreign body injury.METHODS: Totally 256 cases with intraocular foreign bodies including the occurrence of endophthalmitis in 42 cases were analyzed retrospectively.RESULTS: The incidence of endophthalmitis after intraocular foreign body injury was 16.4%.Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury (all P<0.05).Intravitreal injection of vancomycin hydrochloride and ceftazidime in the treatment of intraocular foreign body injury reduced the incidence of endophthalmitis (P<0.05).Types and sizes of intraocular foreign bodies,the time of extraction and the condition of wound had no significant effect on the incidence of endophthalmitis (all P>0.05).Vitrectomy was the main treatment of endophthalmitis.CONCLUSION: Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury.It should be kept the integrity of the posterior capsule of lens in traumatic cataract surgery.Intravitreal injection of vancomycin and ceftazidime is recommended in emergency surgery.Vitrectomy should be performed as soon as possible when confirmed endophthalmitis.

Objective To study the effect of clopidogrel on different CYP2C19 genotypes and platelet reactivity in acute cerebral infarction patients with antiplatelet aggregation.Methods Four hundred and seventy-four cases of cerebral infarction patients in Beijing Tiantan Hospital Affiliated to Capital Medical University from April 2015 to April 2016 were collected.CYP2C19 genotype was determined,and the genotype was divided into the wild type group,the heterozygous type group and the mutant homozygous group.Platelet aggregation inhibition rate(ADP%) and platelet reactivity index induced by ADP were detected.Patients were divided into clopidogrel resistance group(group CR) and non resistant group according to whether ADP% was less than 30.SPSS 16.0 statistical software was used for statistical analysis,the comparison between groups using independent samples t test,chi square test and multivariate analysis using Logistic regression analysis,when P<0.05 difference was statistically significant.Results Among the 474 patients,204 cases(43.04%) were divided into wild-type group,and 204(43.04%) and 66(13.92%) were divided into the mutant heterozygous group and mutant homozygous group.In Chi square test analysis,clopidogrel resistance group and non resistance group CYP2C19 genotype distribution was significantly different(χ2=6.658,P=0.036).CR group angle(α) values((68.87±5.47)°) and MA((66.77±6.25) mm) were higher than that of CS group ((66.55±6.05)° and (63.30±5.66) mm,t=2.199,3.387,P=0.029,0.001).The multivariate logistic regression analysis showed that OR of angle level was 1.028,95%CI was 0.929-1.137 (P=0.595);OR of Ma level was 1.561,95%CI was 0.785-0.970 (P=0.012).Conclusion The effect of clopidogrel on platelet aggregation in patients with acute cerebral infarction is decreased by CYP2C19 gene mutation.CYP2C19 mutant allele is a risk factor for clopidogrel resistance.Angle (α) value and MA value are the risk factors for the diagnosis of CR in the patients with acute cerebral infarction,and the risk of clopidogrel resistance increased when the patients′ Angle (α) value and the value of MA increased.MA value as a predictor of CR and the screening tool has a certain value.

[Objective] To investigate the relationship between the body constitution and the syndromes of the bronchiectasis patients and provide the basis for the clinical treatment.[Methods] Col ected 80 out-patients and in-patients of bronchiectasis in the first affiliated hospital of Zhejiang Chinese Medical University from May 2011 to March 2012. Al patients met with the inclusion criteria, adopted the standardization of physical scale for physical identifica-tion and dialectical type and analyzed the relationship between constitution and syndrome.[Results] ①The gentleness type, qi-deficiency type and yin-defi-ciency type were more popular in the bronchiectasis, fol owed by the phlegm-wet type, wetness-heat type, yang-deficiency type and qi-depression type. The special inherited type and blood-stasis type were very rare. ②The syndrome of phlegm heat obstructing lung was the top one in the Chinese tradi-tional medical syndromes(48.75%).The frequency of liver-fire attacking lung syndrome, hyperactivity of fire due to yin deficiency syndrome and qi-yin de-ficiency syndrome were 21.25%, 18.75% and 11.25% respectively. ③From different body constitution distribution of TCM syndromes in patients with bronchiectasis, it could be found:gentleness type, qi-deficiency type, yang-deficiency type, phlegm-wet type and wetness-heat type were most presented as phlegm-heat stasis lung syndrome. Patients with qi-deficiency type were most presented as qi-yin deficiency syndrome .Patients with Yin deficiency type were always performed as hyperactivity of fire due to yin-deficiency syndrome. Patients with lung qi-stasis type were liver-fire invading lung syn-drome.[Conclusion] Phlegm-heat stasis syndrome was the main syndrome in patients with bronchiectasis. It conformed to the pathological characteristics of deficiency essence with virtual reality. Different body constitutions decided the different traditional Chinese medical syndromes after the disease onset.

Objective Studies show that the ERCC1 gene may be involved in secondary cisplatin resistance.This article aims to investigate the effects of shRNA targeting silencing excision repair cross-complementation group 1 (ERCC1-shRNA) on the proliferation and apoptosis of lung cancer A549/DDP cells treated with different concentrations of cisplatin.Methods Lung cancer A549/DDP cells were divided into a negative control, a blank control, an ERCC1-shRNA1, and an ERCC1-shRNA2 group.Human interfering RNA (RNAi) targeting the human ERCC1 gene was constructed and transfected into the A549/DDP cells using Lipofectamine 2000.The mRNA and protein expressions of ERCC1 in the A549/DDP cells were detected by real-time PCR and Western blot respectively, the proliferation-inhibition rate was assessed by MTT, and their cell cycle and apoptosis were determined by flow cytometry.Results ERCC1-shRNA was successfully constructed and transfected into the A549/DDP cells.Both the mRNA and protein expressions of ERCC1 were significantly lower in the ERCC1-shRNA1 (0.20±0.04 and 0.24±0.10) and ERCC1-shRNA2 (0.47±0.28 and 0.37±0.11) than in the negative control (0.96±0.12 and 1.32±0.13) and blank control groups (0.84±0.07 and 1.45±0.23) (P<0.01).Compared with the negative and blank control groups, the ERCC1-shRNA1 group showed a significantly decreased IC50 value (16.71±2.33 and 16.69±1.69 vs 7.78±0.54, P<0.01) and an increased proportion of G0/G1 phase cells ([72.87±3.23] and [71.75±4.56] vs [82.99±4.23]%, P<0.05), with the cell cycle arrested in the G0/G1 phase.The apoptosis rate of the cells in the ERCC1-shRNA1 group was remarkably lower after treated with cisplatin at the concentrations of 6.25 and 12.5 μg/mL than at 0 μg/mL ([8.17±0.65] and [11.91±1.41] vs [29.97±3.14]%, P<0.05).Conclusion ERCC1-shRNA can inhibit the proliferation and enhance the apoptosis of A549/DDP cells by silencing the expression of the ERCC1 gene.

Objective To investigate the clinical application of anti-β2 glyeoprotein Ⅰ antibodies (IgG, IgM, IgA)in systemic lupus erythematosus(SLE). Methods The anti-β2-GP Ⅰ antibodies and anti-cardiolipin antibodies(ACL) level were measured by ELISA in 100 SLE patients, 39 other rheumatoid arthri-tis patients and 30 healthy control people. Their clinical application was analyzed in SLE diagnose and thera-py. Results The level of anti-β2-GP Ⅰ (IgG, IgM, IgA)were significantly higher in SLE than that in healthy (P < 0. 01 ). Sensitivity, specificity, positive predictive value and negative predictive value were 17.2%, 95.7%, 85.0% and 44. 6%, respectively. There was a significant and positive correlation be-tween anti-β2-GP Ⅰ antibodies and ACL antibodies ( IgG, IgM, IgA) (r = 0.418, 0. 624, 0.518, 0. 583, P <0.01). In multivariate analysis the factors(anti-β2-GP Ⅰ antibodies, ACL antibodies, dsDAN, u1-RNP, Sm, SSA, SSB, Jo-1, Scl-70, P-protein, PT, APTT) associated with SLE disease activity index(SLEDAI) were anti-β2-GP Ⅰ (IgG) and dsDNA. Conclusion anti-β2-GP Ⅰ antibody has high specificity and positive predict value, also is associated with SLE's thrombosis. It has some values in the clinical application.
