ABSTRACT
OBJECTIVE: To investigate the association between the genetic variant of miRNA-1 target gene COG6 rs9548934 CâT and the risk of premature coronary artery disease (pCAD). METHODS: This study included 226 pACD patients and 275 gender and age matched pCAD-free controls hospitalized in our hospital, diagnosis was made based on coronary angiography (CAG) results. The genotypes of miRNA-1 target gene COG6 rs9548934 CâT were detected by PCR-RFLP. RESULTS: Compared with the wide genotype CC, subjects with the variant genotypes CT of rs9548934 CâT was associated with a 45% lower risk of pACD (adjusted OR = 0.55, 95%CI = 0.36 - 0.82, P = 0.003), and the subjects with CT/TT genotypes were also associated with a significantly lower risk of pACD (adjusted OR = 0.64, 95%CI = 0.44 - 0.92, P = 0.015). Using the median serum TG level (1.20 mmol/L) in control group as the cutoff value, subjects with higher serum TG levels were associated with increased risk of pACD after adjustment for age, gender and BMI (adjusted OR = 2.32, 95%CI = 1.57 - 3.41, P < 0.001). In addition, subjects with higher HDL-C levels were associated with significantly lower risk of pACD (adjusted OR = 0.48, 95%CI = 0.31 - 0.75, P = 0.001). Stratified analyses showed that the risk reduction for pCAD in CT/TT genotypes carriers was more significant in the female subjects (adjusted OR = 0.54, 95%CI = 0.30 - 0.97, P = 0.040), and in subjects with lower TG, TC, HDL-C and LDL-C levels (adjusted OR = 0.62, 95%CI = 0.39 - 0.98, P = 0.040; adjusted OR = 0.55, 95%CI = 0.35 - 0.85, P = 0.008; adjusted OR = 0.43, 95%CI = 0.22 - 0.87, P = 0.018; adjusted OR = 0.49, 95%CI = 0.32 - 0.75, P = 0.001, respectively). CONCLUSION: The polymorphism of miRNA-1 target gene COG6 rs9548934CâT is associated with lower risk of pCAD, especially in female subjects and subjects with lower serum lipid levels.

AIM: To predict postoperative intraocular lens (IOL) position using the Sirius anterior segment analysis system and investigate the effect of lens position and IOL type on postoperative refraction. METHODS: A total of 97 patients (102 eyes) were enrolled in the final analysis. An anterior segment biometry measurement was performed preoperatively with Sirius and Lenstar. The results of predicted lens position (PLP) and IOL power were automatically calculated by the software used by the instruments. Effective lens position (ELP) was measured manually using Sirius 3mo postoperatively. Pearson's correlation analysis and linear regression analysis were used to determine the correlation of lens position to other parameters. RESULTS: PLP and ELP were positively correlated to axial length (AL; r=0.42, P<0.0001 and r=0.49, P<0.0001, respectively). There was a weak correlation between the peLP (ELP-PLP) and the prediction error of spherical refraction (peSR; r=0.34, P<0.0001). The peLP of Softec HD IOL differed statistically from those of both the TECNIS ZCB00 and Sensor AR40E IOLs. Multiple linear regression was used to obtain the prediction formula: ELP=0.66+0.63×[aqueous depth (AQD)+0.6LT] (r=0.61, P<0.0001), and a new variable (AQD+0.6 LT) was found to have the strongest correlation with ELP. CONCLUSION: The Sirius anterior segment analysis system is helpful to predict ELP, which reduces postoperative refraction error.
ABSTRACT
OBJECTIVE: To study the proliferation and location of hantaan virus (HV) in gamasid mites and chigger mites. METHODS: HV RNA in gamasid mites and chigger mites were detected by reverse transcription, polymerase chain reaction (RT- PCR) and in situ hybridization. RESULTS: The smallest quantity of mite from which HV RNA could be detected was 5 mites group. The titers of -and proliferated in mites HV RNA could be found in ovary cells and dug cells of gamasid mites and chigger mites by in situ hybridization. CONCLUSIONS: The results showed that HV could be trans-stadially transmitted and proliferated in mites, and HV always located in ovary and dug organs of mites. These results provide direct evidence at molecular level for the role of gamasid mites and chigger mites as vectors in transmission of HV.
