Objective To investigate the clinical effectiveness of fast track surgery ( FTS) nursing during laparoscopic cone-shaped resection of renal tumor. Methods Forty patients who was planned to accept laparoscopic cone-shaped renal tumor resection was divided into either FTS group ( n=20 ) or control group ( n=20 ) according to odd-even number of their admission IDs. The control group was given routine perioperative nursing procedure, and the FTS group was given FTS nursing. Results The operation time, intraoperative blood loss and incidence of complications had no statistical significance between the two groups (P>0. 05). As compared to the control group, patients in the FTS group experienced a shorter anal exhaust time [(30. 3 ± 11. 7) h vs. (43. 0 ± 15. 5) h, t= -2. 924, P=0. 006], shorter post-operative fasting time [(26. 6 ± 12. 1) h vs. (56. 1 ± 18. 1) h, t= -6. 059, P=0. 000], earlier ambulation [(33. 6 ± 16. 8) h vs. (66. 9 ± 28. 6) h, t= -4. 490, P=0. 000], shorter urethral catheterization [(40. 2 ± 18. 5) h vs. (83. 4 ± 39. 6) h, t= -4. 420, P=0. 000], shorter drainage time [(50. 3 ± 22. 5) h vs. (102. 9 ± 46. 0) h, t= -4. 594, P=0. 000], and shorter length of hospitalization [(5. 5 ± 1. 5) d vs. (9. 0 ± 2. 1) d, t= -5. 911, P=0. 000]. Conclusions FTS nursing procedure can reduce the rate of post-operative complications and shorten hospitalization stay. It can not only guarantee the efficacy of surgical treatment but also help the patient to achieve the goal of fast rehabilitation, being worthy of extensive application.

Objective To compare the efficacy and predictability of sphere-cylinder-combined LASIK and two-zone cross-cylinder LASIK for the correction of moderate and high astigmatism.Design Prospective,comparative case series.Participants 40 eyes of 35 patients with mixed astigmatism undergoing LASIK.Methods All patients were treated with Visx Star IV LASIK system.20 eyes of 19 cases were used for sphere-cylinder combined LASIK mode and 20 eyes of 16 cases for two-zone-cross-cylinder LASIK mode.All sub- jects were followed more than 6 months.Main Outcome Measures Uncorrected visual acuity (UCVA),best spectacle-corrected visual acuity (BSCVA),spherical diopter,residual astigmatism and corneal thickness.Results For the patients who received two-zone-cross-cylinder LASIK mode,the UCVA at 6 months after surgery was 0.5 or above,and 13 eyes (65.0%) were 1.0 or above. For the patients who received sphere-cylinder-combined LASIK mode,the UCVA at 6 months after surgery was 0.5 or above,and 11 eyes (55.0%) was 1.0 or above (P=0.683).The residual astigmatism for the patients received sphere-cylinder-combined LASIK mode was (1.15?1.00)D,while for the patients received cross-cylinder LASIK mode was (1.13?0.62)D(P=0.045).The remotion depth of cornea for sphere-cylinder-combined LASIK mode and cross-cylinder LASIK mode was (36.73?13.12)?m and (15.60?6.85)?m,respectively (P= 0.031).Condusion The UCVA,residual astigmatism and corneal thickness after surgery in two-zone-cross-cylinder LASIK mode were better than that in sphere-cylinder-combined LASIK mode for the correction of moderate and high astigmatism.

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 study the efficacy and safety of CO2 laser microsurgery for early glottis carcinoma.Methods The data of 96 cases of early glottic laryngeal carcinoma treated with CO2 laser microsurgery were retrospectively analyzed.Surgical specimens were conventionally embedded with paraffin and serially sectioned.Sections were stained by using hematoxylin-eosin for pathologic examination.The local control rate was observed after operation.Results Among the 96 specimens,88 surgical margins were negative and 8 were positive.10 patients (10.4 ％) recurrenced followed up for 3 years.The recurrence rates of Tis,T1a,T1b and T2 were 0 (0/10),4.1％ (2/48),25.0 ％ (4/16) and 18.1％ (4/22),respectively,with significant differences among groups (X2 =6.105,P ＜ 0.05).All of 8 cases with positive margin and 2 cases with negative margin were recurrened.The recurrent rate of patients with involvement of the anterior commissure was 30.0 ％ (6/20),which was higher than that of patients with no tumor invasion [5.3 ％ (4/76)] (X2 =9.624,P ＜ 0.01).Conclusions The safe edges can be obtained by CO2 laser microsurgery for early stage of glottis carcinoma,which have advantages in local control rate,vocal function of the larynx and curative effect.

AlM: To examine the retinal nerve fiber layer ( RNFL ) changes in early primary open angle glaucoma ( POAG ) by comparing the superior half of the optic disc with the inferior disc half.METHODS: lt was a clinical observational study. The study included 30 patients ( 39 eyes ) with POAG and 20 normal subjects ( 40 eyes ) . Visual field was tested by Zeiss Humphrey750 and the optic disc topographic parameters and RNFL thickness were measured by Zeiss Cirru HD-OCT. Collecting information included visual field mean defect ( MD ) , glaucoma hemifield test ( GHT ) , intraocular pressure ( lOP ) , C/D ratio and RNFL thickness. Data were analyzed by statistic software SPSS18. 0. The differences between two groups were assessed using t test.RESULTS: The differences of superior RNFL minus inferior RNFL thichness on the corresponding clock-hour locations were caculated in two groups. There was a significant difference in superonasal- inferonasal RNFL thickness between two groups (t=2. 526, P=0. 014), and there were no significant differences in the others ( all P>0. 05).CONCLUSlON: The asymmetry of optic disc hemifield RNFL is found in early primary open angle glaucoma patients. The superonasal RNFL ( 1 o’clock for right eye, and 11 o’clock for left eye ) is more fragile to loss than inferonasal RNFL (5 o’clock for right eye, and 7 o’clock for left eye) .
