In order to change the situations such as students’passivity and low enthusiasm in the traditional experimental teaching of Microbiology and improve students’comprehensive qualities,exploration and attempt on experimental teaching reforms including teaching contents,teaching modes,laboratory management and evaluation system of examination were done.Teaching practices showed that the normalized ex- periment syllabus based on the correct orientation of experimental teaching of Microbiology,the actualization of teaching mode of basic skill training-integrated experiment-designed experiment and the management of opening laboratory were effective measures in improving experimental teaching of Microbiology.

AIM:To observe the clinical effects of 23-gauge (23G) transconjunctival sutureless vitrectomy for idiopathic macular hole.
METHODS: In this retrospective study, 28 eyes of 28 consecutive patients who underwent 23 - gauge transconjunctival sutureless vitrectomy for idiopathic macular hole between January 2013 and October 2013 in our hospital were evaluated. The follow-up time was 3-12mo. The operation effects were analyzed.
RESULTS:The macular hole was closed in 27 eyes of 28 eyes which underwent 23G transconjunctival sutureless vitrectomy and not closed in 1 eye after surgery. Best-corrected visual acuity at postoperative 1, 3mo was significantly improved compared to pre-operation (χ2=8-65, P=0. 003;χ2=10. 33, P=0. 001). The macular hole was closed as shown by OCT. Intraoperative incision was sutured in 5 cases ( 18%) . There was no statistically significant difference in intraocular pressure between pre-operation and post - operation. No post - operative complications such as endophthalmitis, retinal detachment, vitreous hemorrhage came up.
CONCLUSION: 23G transconjunctival sutureless vitrectomy is observed to be safe and effective technique in the treatment of macular hole. It is therefore our preferred system for straightforward macular surgery.
