ABSTRACT

AIM:To explore the changes of intraocular pressure measured by noncontact tonometer (IOPNCT) with high myopia and analyze the relative fators after small incision lenticule extraction(SMILE).METHODS:A retrospective study.Totally 108 cases (216 eyes) with high myopia received SMILE during March 2015 to October 2016 were involved.The IOPNCT, corneal central thickness (CCT) and corneal curvature for 3mo were recorded and analyzed by ANOVA, LSD t test.The Pearson correlation analysis and multiple linear regression model analysis were used to evaluate the relationship between IOPNCT and its influence factors.RESULTS:(1) There was significant statistical difference in IOPNCT after SMILE at 1d, 1wk, 1 and 3mo compare with preoperative (t=17.785, P=0.019;t=17.981, P=0.016;t=18.841, P=0.012;t=19.364, P=0.001);the IOPNCT after SMILE decreased.The IOPNCT values at every time after SMILE was no statistical difference (t=1.871, P=0.818;t=3.062, P=0.328;t=1.143, P=0.373).(2) The IOPNCT in high myopia were positive correlated with CCT and corneal curvature after SMILE (r=0.4356, 0.295;P<0.05), respectively.(3) The multiple linear regression model analysis revealed that Y=-14.601+0.348X1+0.03X2 (Y was IOPNCT, X1 was corneal curvature, X2 was CCT,P<0.001);Y=3.679+0.28X1+0.012X2 (Y was△IOPNCT,X1 was variation of corneal curvature,X2 was△CCT, P<0.001).CONCLUSION:The IOPNCT decreased after SMILE in high myipia, and it showed that there was no significant influence to use glucocorticoid eye drops in short terms.There was positive correlation among IOPNCT, CCT and corneal curvature after SMILE.

ABSTRACT

A typical clinical case of taking Dictamni Cortex(Baixianpi) powder was analyzed to study liver damage caused by Dictamni Cortex. Liver damage was diagnosed according to the integrated evidence chain method recommended by the Guideline for Diagnosis and Treatment of Herb-Induced Liver Injury. By analyzing clinical history and biochemistry and imaging examinations, underlying diseases, such as viral hepatitis, autoimmune liver disease and alcoholic liver disease, were excluded. Through the investigation of medication history, we made it clear that the patient only took Dictamni Cortex powder during the period, and thus suspected that the liver injury was induced by Dictamni Cortex. Furthermore, the quality of the drug was tested, and the results showed it was consistent with the quality standard of Chinese Pharmacopoeia. DNA barcoding showed that the drug was 100% similar with Dictamnus dasycarpus. Moreover, exogenous harmful substances and chemical drug additions were tested, and the results showed that the content of heavy metal, pesticide residues and microbial toxin were consistent with the required standards, and no chemical drug additions were found in Agilent Fake TCM-Drugs database. In summary, we confirmed that the clinical case of drug-induced liver injury was induced by D. dasycarpus with the dose of 15 g•d⁻¹, which exceeded the prescribed amount of Chinese Pharmacopoeia. According to the Guideline for Diagnosis and Treatment of Herb-Induced Liver Injury, the case of drug-induced liver injury induced by D. dasycarpus was confirmed, which provided a direct and reliable evidence for the study of risk of liver injury induced by D. dasycarpus and its relevant preparations.

ABSTRACT

?The small incision lenticule extraction ( SMILE ) with femtosecond laser is a new mode of corneal refractive surgeryrecently. The safety, efficacy, stability and predictability of SMILE lead the corneal refractive surgery to a new world that only use femtosecond laser to correct myopia.With the development and popularity of SMILE, the clinical effect has aroused much concern.But there remain exited disputes in refractive stability, visual quality and corneal biomechanical property, contrast sensitivity and glare symptoms, corneal sensitivity and dye eye, corneal endothelial cells and intraocular pressure.These will be summarized in this review.

ABSTRACT

<p><b>OBJECTIVE</b>To assess the association between single nucleotide polymorphisms (SNPs) of mannose-binding lectin 2 gene (MBL2) (rs1800450, rs1800451 and rs11003125) and protein kinase C-beta 1 gene (PRKC beta 1) (rs3700106, rs2575390) with diabetic macroangiopathy in northern Chinese Han population.</p><p><b>METHODS</b>The samples have included 318 type 2 diabetes mellitus (T2DM) patients and 448 normoglycemic controls. The five SNPs were determined by a Multiplex SnaPshot method. Biochemical indices such as fasting plasma-glucose, triglyceride and total cholesterol were also measured. Linkage disequilibrium and haplotype analysis were carried out for all samples using Haploview 4.2. Additive model was applied to assess the effect of interaction between SNPs and environment factors on macrovascular complications.</p><p><b>RESULTS</b>Genotypic frequencies of rs11003125 have differed significantly between the controls and patients with coronary heart disease and peripheral vascular disease (P=0.024 and 0.004, respectively). The allele frequency of rs11003125 was also statistically significant between the two groups (P=0.014 and 0.001, respectively). Compared with patients without macrovascular complications, the allele frequency of rs11003125 was significantly different in patients with peripheral vascular disease (P=0.031). No significant differences were found between the distribution of the genotype frequency and allele frequencies of other variants. Haplotype analysis indicated that, compared with controls and patients without macrovascular complications, individuals with G allele of rs1800450 and C allele of rs11003125 had a higher risk for macrovascular complications.</p><p><b>CONCLUSION</b>The rs11003125 polymorphism located in the promoter region of MBL2 gene is associated with macrovascular complications of T2DM in northern Chinese Han population. G allele of rs1800450 and C allele of rs11003125 may be risk factors for macrovascular complications. There were additive interactive effects for rs11003125 polymorphism (GC+CC) and hypertension, diabetic nephropathy, diabetic neuropathy and diabetic retinopathy on macrovascular complications.</p>

ABSTRACT

Objective To investigate whether the mannose-binding-lectin 2 (MBL2) gene was associated with type 2 diabetes in the populations living the northern part of China. Methods The study involved 318 type 2 diabetic patients and 448 normoglycemic controls. The variances of rs1800450, rs1800451 and rs11003125 were determined by the Multiplex SNaPshot method. Fasting blood-glucose, triglyceride and total cholesterol were also measured. All of these results were analyzed by logistic regression method. Linkage disequilibrium and Haplotype measures were computed in all samples using Haploview. Results There seemed no mutation on rs 1800451 while the rs 1800450 and rs11003125 polymorphism was consistent with Hardy-Weinberg expectations in both the case and the control groups. Genotypes and allele frequencies of rs1800450 as well as rs11003125 were observed (P=0.006, P=0.003) and (P=0.010, P=0.004), respectively. Data from logistic regression analysis revealed that factors as overweight, abdominal obesity, hypercholesterolemia, GG genotype frequencies of Exonl rs1800450 polymorphism as well as (GC + CC) genotype frequencies of rs11003125 polymorphism in MBL2 conferred increased risks for type 2 diabetes. Haplotype analyses of the two SNPs (rs1800450, rs11003125) revealed similar effects as compared with the single SNP associations. Only haplotype constructed from GC alleles conferred increased trends for type 2 diabetes (OR=2.21, 95% CI: 1.47-3.33, P=0.000). Conclusion Our result suggested that the Exonl rs1800450 polymorphism and promoter region rs11003125 polymorphism in MBL2 gene were both associated with type 2 diabetes in the Chinese population living in the northern areas of China. The G allele of rs 1800450 and C allele of rs 11003125 might be the risk factors of type 2 diabetes.
