Objective　To investigate the association betwee n the β3-adrenergic receptor gene (β3-AR) and obesity. Methods　147 patients with obesity and 106 controls were selected. Genotype of the β 3-AR was determined by polymerase chain reaction (PCR) and restriction fragme nt length polymorphism methods (RFLP). Body mass index (BMI) was detected. Results　The frequency of Arg64 allele of β3-AR gene in the obesit y g roup (20.3%) was significantly higher than those in the control group (10.2%) ( P=0.001) . The distribution of Trp64Arg and Arg64Arg genotype in the patient group (38.7% and 0.9%) were both higher than that in the control group (19.0% and 0.7%). In the female subj ects, the Trp64Arg mutation and frequency of Arg64 allele of the β3-AR gene in the obesity group(40.6% and 20.3%) were also higher than those in control (16 . 7% and 9.5%)(P<0.01). Conclusions　These results suggest th at the Trp64Arg mutation of the β3-adrenergic-receptor gene may be associat ed with increased body fat.

AIM: To analyze the control effect of orthokeratology(OK)combined with atropine of low concentration on moderate to low myopia in adolescents.

METHODS: Totally 76(152 eyes)adolescents with moderate to low myopia who were admitted to the department from January 2016 were enrolled. According to the voluntary principle, they were divided into orthokeratology group(OK group, n=36 cases, 72 eyes)and orthokeratology combined with atropine of low concentration group(combination group, n=40 cases, 80 eyes). The OK glasses were given for the two groups. The combination group was additionally given 0.1g/L atropine eye drops. All were followed up for 1a. The changes of uncorrected visual acuity, diopter, axial length, intraocular pressure, tear film function and corneal parameters were measured before and after wearing glasses. The incidence of complications was statistically analyzed.

RESULTS: There were no significant differences in uncorrected visual acuity, diopter, axial length and intraocular pressure between the two groups before wearing glasses and at 1a of wearing glasses(P>0.05). The change of uncorrected visual acuity before wearing glasses and at 1a of wearing glasses of combination group was higher than that of OK group while the differences in diopter and axial length were lower than those of OK group(P<0.05). Before wearing glasses, there were no significant differences in the lipid layer thickness(LLT), object scattering index(OSI)or tear film rupture time(tear film break-up time, BUT)between the two groups(P>0.05). At 1a of wearing glasses, LLT and BUT of combination group were higher than those of OK group while OSI was lower than that of OK group(P<0.05). Before wearing glasses, there were no significant differences in corneal curvature, corneal thickness or anterior chamber depth between the two groups(P>0.05). At 1a of wearing glasses, the changes of above indexes of combination group were lower than those of OK group(P<0.05). There was no significant difference in the incidence of complications between the two groups(P>0.05).

CONCLUSION:OK glasses combined with atropine of low concentration can improve the uncorrected visual acuity of adolescents with moderate to low myopia, control the increase of diopter and axial length. And there is significant negative influence on corneal morphology and tear film function, and with high safety.

Objective To evaluate the dynamic changes of cell mobility of renal tubular epithelial cells in the course of epithelial-mesenchymal transition(EMT) and their effect on cell cycle.Methods NRK-52E cells were cultured in vitro and treated with 5 μg/L transforming growth factor(TGF)-β1 to induce EMT.The cell mobility was assessed by using Transwell chamber assay and flow cytometry (FCW) after being treated with TGF-β1 for 4 h,8 h,12 h,24 h and 48 h.The proliferative cell cycle of NRK-52E cells were evaluated by using the FCW.Results 1.EMT was successfully induced by TGF-β1.After being treated by TGF-β1 (5 μg/L),the morphological changes of NRK-52E cells were found with loose cell arrangement and elongated fusiform change in cells body.Meanwhile,after getting treated by TGF-β1,the expressions of E-cadherin protein(epithelial marker) of NRK-52E cells were significantly decreased with time-dependent (P ＜ 0.05),while the expressions of α-smooth musle actin (α-SMA) (mesenchymal cell marker)were significantly increased with time-dependent (P ＜ 0.05).2.The Transwell chamber assay showed that compared with the control group,the cell mobility in the group treated with TGF-β1 was significantly enhanced from 12 h after getting treated with TGF-β1 (P ＜ 0.01).3.The proliferative cell cycle of NRK-52E cells showed no significant difference after being treated with TGF-β1 (P ＞ 0.05).Conclusions The migration ability of the NRK-52E cells are increased incessantly in the course of EMT,which is induced by TGF-β1 without the influence of cell proliferation in vitro.

·AIM:To investigate the factors related to the decrease of corneal endothelial cell number after phacoemulsification in cataract patients. ·METHODS: We selected 98 patients (120 eyes) in Ophthalmic Center from July 2014 to July 2016 underwent phacoemulsification and they were retrospectively analyzed. According to the central corneal endothelial cell density before and 2mo after the operation, they were divided into serious loss group of 52 cases (67 eyes, density of central corneal endothelial cells loss rate no less than 12.3%),the general loss group of 46 cases (53 eyes, the density of central corneal endothelial cell loss rate <12.3%). Relevant indicators of general information, operation of the two groups were compared, the influence factors of non conditional Logistic regression analysis method was used to investigate the effect for corneal endothelial cell loss in cataract patients. ·RESULTS:Serious loss group and the general group on gender, rate with hypertension, rate with diabetes, rate with high blood lipids, with shallow anterior chamber, corneal diameter and suction time comparison, had no statistically significant differences (P > 0. 05). Nuclear hardness classification of Emery lens, ultrasonic power, ultrasonic emulsification time, age between groups were significantly different(P<0.05). By using Logistic analysis method, the results showed that increased Emery lens nucleus grading, ultrasonic energy, phacoemulsification time, age were independent risk factors for corneal endothelial cells after phacoemulsification (P<0.05). ·CONCLUSION: The main factors that influence the decrease of corneal endothelial cell number after phacoemulsification are Emery lens, higher grade of nucleus of lens, increase of ultrasonic energy, longer time of phacoemulsification and increased age.
