To evaluate the clinical effect of laser in situ keratomileusis ( LASlK) with the corneal flap created by FEMTO LDV femtosecond laser for myopia.
●METHODS: The corneal flap was created by the FEMTO LDV femtosecond laser, and the thickness of the flap was 110μ m. A total of 143 myopic patients (283 eyes) were treated with the EC5000 - CXlll element laser. The optometry of the eye, best corrected visual acuity (BCVA) the thickness of the cornea, and ObscanⅡ were examined before the operation. The thickness of the flap was calculated by measuring the thickness of corneal bed during the operation in 35 eyes. The conditions of the corneal flap, complications, uncorrected visual acuity ( UCVA ), diopter, corneal topography were observed during and after the operation and were checked for 3mo follow-up.
●RESULTS: During the operation, it appeared small flap ( diameter < 5mm ) in 3 eyes, corneal margin incised incompletely in 5 eyes and incision bleeding in 8 eyes. Postoperative subconjunctival hemorrhage appeared in 6 eyes. The thickness of corneal flap in 35 eyes was 108. 75± 8. 52μ m (98-117μ m) and the error was 6. 49±8. 62μ m (3-12μ m). There was no significant difference between the actual flap thickness and the preset flap thickness ( P >0. 05) . The average equivalent spherical refractive was -0. 29± 0. 47 ( - 1. 50 to + 1. 00) DS after the operation for 3mo and the UCVA met or exceeded preoperative BCVA in 251 eyes (88. 7%).
●CONCLUSlON: The operation of myopia by LASlK flap created by FEMTO LDV femtosecond laser has fewer complications, and the effect is definite and safe.

Objective To investigate the incidence of needle stick injuries of nursing students in different stages of clinical practice and occupational protective education to provide evidence for developing education strategies. Methods One hundred and forty-one nursing students were surveyed retrospectively by a self-designed questionnaire. Results A total of 75.9%(107/141) nursing students had been injured in clinical practice. The incidence of needle stick injuries varied in different stages of clinical practice. Compared with the middle and late stage of clinical practice, the incidence of needle stick injuries was highest in the early stage of clinical practice:53.9%(76/141) vs. 38.3%(54/141),7.8%(11/141),and there was significant difference, χ2=216.14, P<0.05.About 64.2%(88/141)-78.0%(110/141) nursing students had not received protective education on the needle stick injuries. Only 48.9%(69/141)-55.3%(78/141) of nursing students were given protective training on needle stick injuries in their practice hospitals. Before clinical practice, 63.1%(89/141) nursing students had not been vaccinated to prevent infective diseases. Conclusions To reduce the incidence of needle stick injuries and related potential risks of infection caused by injuries, it is necessary to strengthen pre-practice education on occupational protection among nursing students. Perfect supervision system should also be established in practice hospitals and clinic wards.

Objective To investigate the application value of virtual touch tissue quantification (VTQ) technique in staging of chronic kidney disease (CKD). Methods VTQ examination was performed on a random sample of 96 CKD patients at different clinical stages and 45 healthy volunteers (control group). Shear wave velocity (SWV) of renal parenchyma was measured and compared. Correlation between SWV and clinical stage and glomeru-lar filtration rate (GFR) of CKD patients was analyzed. Results The SWV value of renal parenchyma decreased gradually, along with the progression of CKD disease and impairment of renal function. There was no significant difference(P>0.05)between the control group and the CKD1 group ( P=0.061), the CKD2 group and the CKD3 group (P = 0.238), and the CKD4 group and the CKD5 group (P = 0.624). The difference of SWV between the remaining groups was statistically significant(P < 0.05). SWV of renal parenchyma was negatively correlated with CKD stage (r =-0.65, P < 0.001), which means the higher the stage of CKD was associated with the lower the SWV. SWV was positively correlated with GFR (r = 0.73, P < 0.001), which means the lower the GFR was related to the lower the SWV. Conclusion VTQ technique can noninvasively reflect the changes of renal parenchyma elas-ticity and evaluate the impairment of renal function in CKD patients. It can provide a new quantitative evaluation index for the clinical staging of CKD.
