Background Epipolis laser in situ keratomihusis(Epi-LASIK) is an potential surgery for myopia because it synthesize advantages of LASEK and LASIK. But its clinical effectiveness and safeness is remarkable.Objective This study was to evaluate the clinical curative effects and safeness of Epi-LASIK for myopia in different diopter of population. Methods Retrospective study was designed for 208 eyes of 104 patients who underwent EpiLASIK for the correction of myopia. The patients were divided into two groups according to preoperative diopter:lower myopia group( ≤ -6.00 D, 111 eyes) and high myopia group ( ＞-6.00 D,97 eyes). The time of epithelial healing, postoperative syndrome, postoperative visual acuity, refraction, intraocular pressure (IOP) , the safe index, the efficacy index and haze were evaluated at 1,3,6,12 months postoperatively. The written informed consent was obtained from each individual before surgery. Results After operation, 20 eyes ( 18.02% ) of lower myopia group and 29 eyes (29.90%) of high myopia group had obvious pain, presenting statistically significant difference between two groups (X2 = 4. 060, P＜0.05 ). The mean time of epithelial healing was (5.49±0. 83 )days in lower myopia group and (5.85± 0.68 )days in high myopia group with a delayed epithelial healing time in high myopia group( u= 3. 377 ,P＜0.05 ).One year after the treatment,the uncorrected visual acuity( UCVA ) ≥ 1. 0 was 90. 99% ( 101 eyes) in lower myopia group and 75.26% ( 73 eyes) in high myopia group, and 9.91% ( 11 eyes) and 15.46% ( 16 eyes) of the eyes improved byl line or more in best spectacle corrected visual acuity(BCVA) ;whereas 3.60% (4 eyes)and 6. 18% (6 eyes)lost a line or more. 91.89% ( 102 eyes) and 85.57% (83 eyes) in both groups gained within 1.00 D of the attempted correction. The safety index and efficacy index were 1.04 and 0. 98 in lower myopia group,and 1. 01 and 0. 96 in high myopia group without statistically significant difference( P＞0. 05 ). haze occurred in 6 eyes in lower myopia group and 9 eyes in high myopia group and the difference in haze grading was not statistically significant between two groups ( P＞0. 05 ). The high intraocular pressure appeared in 10 eyes and 9 eyes in low myopia group and high myopia group respectively during the fellow up duration and back to normal after topical use of timolol. Conclusion Epi-LASIK is an effective and safe method for correction of different diopters of myopia because of its mild symptom and lower incidence of haze.

OBJECTIVETo compare the early clinical effects of Activ C cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) in treating single-level cervical spondylosis.

METHODSThe clinical data of 76 patients with single-level cervical spondylosis underwent surgery from July 2009 to September 2012 were retrospectively analyzed. Among them, 28 patients were treated with ACDR (ACDR group), including 18 males and 10 females, aged from 32 to 62 years old with an average of (45.2±6.2) years; and 48 patients were treated with ACDF (ACDF group), including 28 males and 20 females, aged from 33 to 60 years old with an average of (45.8±6.4) years. Visual analogue scale (VAS), Japanese Orthopedics Association (JOA) score, Short Form-36 (SF-36), imaging data were used to assess the clinical effects after operation.

RESULTSA total of 76 patients were followed up from 6 to 24 months with an average of 13.2 months. VAS of neck pain and brachialgia were improved in all patients after operation (P<0.05), there was no significant difference between two group (P>0.05). Somato-score and psycho-score of SF-36 of two groups were obviously increased (P<0.05), ACDR group was better than that of ACDF group (P<0.05). In ACDR group, there was no significant difference in the range of motion of surgical segments and adjacent segments between preoperative and postoperative (P>0.05); heterotopic ossification around the edge of vertebral body occurred in 1 case on the 6th month after operation, no fusion was found on the 1st year after operation. In ACDF group, the adjacent vertebral disease occurred in 1 case and the patient underwent the reoperation.

CONCLUSIONActiv C cervical disc replacement can reduce the degeneration of adjacent segments and its early outcomes for the treatment of single-level cervical spondylosis are satisfactory, but the long-term effects still need study.

Objective To investigate the effects of short-term continuous subcutaneous insulin infusion (CSII) on plasma visceral adipose tissue-derived serine protease inhibitor ( vaspin ) levels in patients with recentonset type 2 diabetes mellitus, and to study the association between insulin sensitivity and vaspin levels.Methods Thirty patients with recent-onset type 2 diabetes mellitus were treated with CSII for 2 weeks.Euglycemic-hyperinsulinemic clamps (EHC) were performed to evaluate the insulin sensitivity in type 2 diabetes group. Plasma vaspin levels were measured by an ELISA kit. The association between plasma vaspin levels and metabolic parameters were analyzed. Results Fasting plasma vaspin levels were higher in type 2 diabetes than in impaired glucose regulation and normal glucose tolerance groups [( 1.83±0.55 vs 0. 43±0.21 and 0.56±0.26) ng/ml,P＜0.05]. With CSII,vaspin levels [( 1.19 ±0.57 vs 1.83 ±0.55 ) ng/ml, P＜0.05] and homeostasis model assessment for insulin resistance [HOMA-IR ,2.30 ( 1.09-7.2 ) vs 4.28 ( 1.7-6.47 ), P＜0.05] were significantly decreased,accompanied with an increase in glucose metabolic rate [(5. 10±0.51 vs 2.99±0.42 )mg·kg-1·min-1 ,P＜0.05] in type 2 diabetes group. Changes in circulating vaspin concentrations were correlated positively with changes in HOMA-IR. Conclusion In type 2 diabetic patients,elevated plasma vaspin levels are significantly decreased after CSII treatment. Vaspin may play a role in improving insulin sensitivity of diabetic humans.

Objective To evaluate the effect of bispectral index (BIS) and muscle relaxation monitoring on robot-assisted laparoscopic radical prostatectomy in elderly patients.Methods One hundred elderly patients (aged 65-80 years,ASA Ⅰ or Ⅱ) who underwent robot-assisted laparoscopic radical prostatectomy were randomly allocated into BIS and muscle relaxation monitoring group (group AA,n=50) and control group (group AC,n=50).In group AA,propofol was infused to achieve the BIS value of 45-55,and we monitored the muscle relaxation to conduct closed-loop infusion of cisatracurium.In group AC,we regulated the depth of anesthetic with the patients` vital signs according to anesthetists` experience.Mean arterial pressures (MAP),heart rates (HR),airway platform pressure (Pplat),and airway peak pressure (Ppeak) were recorded at following time points: before anesthesia induction (T0),after anesthesia induction (T1),10 min (T2),60 min (T3) after artificial pneumoperitoneum,and the end of operation (T4).We recorded dosage of propofol,cisatracurium,sufentanil,remifentanil,vasoactive agent,extubation time and PACU stay time.Results At T1,T2 and T4,the MAP and HR in group AC were significantly higher than those in group AA (P<0.05);at T3,MAP in group AC were apparently lower than those in group AA (P<0.05).Compared with T0,MAP and HR in group AC were significantly increased at T1,T2 and T4(P<0.05),MAP in group AC were obviously reduced at T3 (P<0.05),MAP and HR in group AC were also fluctuated obviously at different time points.MAP and HR in group AA at each point had no statistically significant difference.Compared with T1,Pplat and Ppeak in the two groups were significantly increased at T2-T4 (P<0.05).Pplat and Ppeak in grpup AC were higher than those in group AA at T2,T3 (P<0.05).Compared with group AC,the dosages of propofol and cisatracurium were less in group AA.The postoperative extubation time and PACU stay time were shorter in group AA.Conclusion BIS and muscle relaxation monitoring in robot-assisted laparoscopic radical prostatectomy can effectively stablize hemodynamics,reduce airway pressure fluctuation and the dosage of anesthetics.It also shortens the extubation time and the PACU stay time and improves the anesthesia recovery quality.

Objective To establish contusion brain injury model in rats, and investigate the efficacy of intravenous administration of neural stem cells(NSC) on posttraumatic neurocognitive function recovery and NGF expression in rats. Methods Cerebral contusion model in motor-sensory cortex of the right parietal cortex in rat was established by a 50 g-weight hammer falling respectively from 30 cm height along guide stick to impact collision pole by improved trauma device for model of contusion brain injury based on Feeney method. And the NSC isolated from GFP transgenic mice were injected intravenously via the tail vein 24 h after the brain trauma, and 1 week later neurocognitive function scores and NGF immunostaining were performed to explore the efficacy of NSC transplant. Results The NSCs from the GFP transgenic mice gathered at the injury site 1 weeks after transplants.Neurocognitive function scores and NGF-positive cells measurement(226 ±27,23 ±4 ) in the treatment group revealed significant increase than in the brain trauma group(300 ±36;15 ±3 )(P＜0.05). Conclusion The intravenous NSC injection in rats can survive and migrate to the injured brain region and promote the post-injury neurocognitive function restoration. The increase of NGF expression may underline one of most important mechanisms in NSC treatment' s rats after brain injury.
