●METHODS: Totally 33 patients ( 33 eyes ) with eye trauma underwent combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule and phase Ⅱposterior chamber lOL implantation. After follow - up of 6mo, visual acuity, intraocular pressure ( lOP ), lOL position, and intraoperative and postoperative complications were observed.
●RESULTS: Visions of all the patients were improved at varying degrees. After follow-up of 6mo, no obvious lens deflected and serious complications ( glaucoma, retinal detachment) appeared.
●CONCLUSlON: Combined lensectomy with vitrectomy, retaining the peripheral anterior lens capsule for ocular trauma has good curative effects of lessening complications during operation and postoperation and good visual acuity recovery.

AIM:To investigate the changes of subfoveal choroidal thickness ( SFCT ) in central serous chorioretinopathy ( CSCR) eyes and to compare them with normal control eyes.
METHODS: This was a case-control study and a Meta-analysis. Forty - six CSCR patients diagnosed by the fundus pre - set lens, fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) were enrolled in this study. Sixty two age-, sex-, diopter- and axial length-matched 62 normal subjects ( 62 eyes ) were enrolled in this study as the control group. Using enhanced depth imaging optical coherence tomography ( EDI-OCT) , SFCT of CSCR eyes and normal control eyes were measured and compared. Univariate and multivariate linear regression analysis were performed to assess the association between SFCT and clinical factors. The Meta - analysis were conducted using the Stata software package to calculate the summary weighted mean differences ( WMDs) .
RESULTS:The mean SFCT of the CSCR group and the normal control group was 397. 34±83. 91μm and 274. 48±62. 57μm, respectively. The CSCR eyes had a thicker choroid than the control eyes at the SFCT (P<0. 01). Univariate and multivariable linear regression analysis showed that the SFCT was significantly thicker in association with the CSCR diagnosis. The result of our case-control study was consistent with the results of the further Meta-analysis with the pooled WMD of 156. 13μm (95% CI:137. 43, 174. 83) for SFCT.
CONCLUSION:Along with the comprehensive Meta-analysis, SFCT in CSCR eyes was thicker than that of normal control eyes. Increased SFCT might be associated with CSCR.

AIM:To study the efficacy and safety of Toric implantable contact lens (TICL) implantation in the treatment of patients with high myopia and astigmatism.METHODS: Totally 90 patients (178 eyes) diagnosed as this disease were selected in our hospital during September 2012 to September 2016 by the method of random.The UCVA, BCVA, refraction, astigmatism coefficient, corneal endothelial cell, intraocular pressure, manifest refraction examination were accessed and compared before and after 3 and 9mo of surgery.RESULTS: After 3 and 9mo of the surgery, the UCVA and BCVA were much higher than those before treatment, which the difference was statistically significant (P<0.05).We compared the refraction at 3mo (-0.52±0.23D) and 9mo (-0.54±0.16D), the astigmatism coefficient at 3mo (-0.39±0.23D) and 9mo (-0.33±0.56D) after treatment, and we found that the differences were not statistically significant (P>0.05).The corneal endothelial cells at 3 and 9mo after operation were compared with those of before treatment, and we found that the differences were statistically significant (P<0.05).The intraocular pressure of 3 and 9mo after operation was compared with that before operation, and we found that the differences were not statistically significant (P>0.05).CONCLUSION: TICL implantation in the treatment of patients with high myopia and myopic astigmatism has a more obvious clinical efficacy and safety and reliability.

Late intraocular lens dislocation is one of the most severe late complications after phacoemulsification.It often occurs 3mo after the surgery.Different from early intraocular lens dislocation, late intraocular lens dislocation is caused by zonular dehiscence and contraction of the capsular bag many years after phacoemulsification.In recent years, the incidence of late intraocular lens dislocation gradually increases, having a risk of 0.1% after 10a and 1.7% after 25a.In the long-term follow-up patients who underwent cataract surgery, 90% had zonular insufficiency and capsular contraction.Among the multiple factors which may contribute to zonular weakness and capsular contraction, pseudoexfoliation is the most common cause, accounting for 50% of all the cases.Other risk factors include aging, high myopia, uveitis, trauma, previous vitreoretinal surgery, retinitis pigmentosa, diabetes mellitus, atopic dermatitis, previous acute angle-closure glaucoma attack, and connective tissue disorders.The understanding of these predisposing factors will suggest necessary preventions for high-risk patients in the future.

AIM: To investigate the topography of the anterior surface of the human crystalline lens. ·METHODS: A Non-contact three-coodinate measuring system was utilized to scan the anterior surfaces of 8 human eye lenses in vitro. Acquired data were processed and computer models of the anterior lens surfaces were made using the program (Surfacer v 10.0). The to-pography of the anterior lens surfaces were established. Radii of curvature were measured at preset spots over the lens surfaces and two way analysis of variance was performed. The data were analysed to determine whether the radius of curvature varied systematically with the position on the lens surface from which the measurement was made. Lens surface asymmetric index (LSAI) was defined and calculated. The vertical and horizontal meridians of the modeled lens were calculated, and the best curve fit to any conic section was determined. ·RESULTS: The topography of the anterior lens surface indicated that the central zone (the central radius of curvature is (9.09±0.80)mm was steeper than that of the peripheral zone(17.05±2.20)mm. Two way analysis of variance of the radii of curvature at preset spots over the lens surfaces showed that the differences were statistically significant (P ＜ 0.05). Curve regression of radii of curvature at preset spots and their distances to the surface center revealed that the correlation of them was the third power function. LSAI increased steadily from the lens surface center(0.013±0.005) to the periphery(0.184± 0.065). The dots on the horizontal and vertical meridians were fit to four kinds of curves, and the determinate coefficient of hyperbola fit were the largest (0.9989-0.9999). ·CONCLUSION: The anterior lens surface is imperfectly rotational symmetric. Moreover, the nearer to the center, the more rotational symmetric it is. Radii of curvature increase nonlinearly from the surface center to the periphery. Anterior lens surface is typically hyperbolic.

Objective To investigate the clinical incidence and influence of prostatic calculi on recalcitrant chronic abacterial prostatitis (CAP). Methods During August 2004 and March 2005, a total of 104 men with recalcitrant CAP refractory to multiple prior therapies were included in the study. Severity of symptoms in these patients was defined by the Chronic Prostatitis Symptom Index (CPSI). The detection and volume measurement of prostatic calculi, and the measurement of prostate volume were performed by ultrasonography. Associations between severity of symptoms and prostatic calculi were assessed using SNK ?2 tests and Spearman correlation. Results Prostatic calculi were detected in 58 of the 104 men (55.8%), including type Ⅱ calculi (larger, coarser) in 31.7% of cases. Mean patient age was significantly older in men with type Ⅰ calculi (small, multiple) than with type Ⅱ calculi or without calculus (P

Results In the untreated control group hematuria recurred in 20/31 within a year but in only 7/28 in the finasteride group,which was a statistically significant difference (P

Objective To investigate the use and effect of subcutaneous flap and tunica vaginalis flap in hypospadias repair and hypospadias fistulas repair. Methods A total of 73 cases of hypospadias and hypospadias fistulas following surgery were included.The new urethras or closed fistulas were wrapped with various types of subcutaneous flaps or tunica vaginalis flaps.In the 45 cases of hypospadias,dorsal dartos flap technique was used in 27,tunica vaginalis flap technique in 3,and adjoining pedicle advance dartos flap technique in 15.In the 28 cases of urethral fistulas,dorsal dartos flap technique was used in 4,X-V skin flap technique in 14,and adjoining U-shaped subcutaneous flap technique in 10. Results All the cases were followed up for 3 to 36 months.Of the 45 cases of hupospadias, fistulas occurred in 3.Of the 28 cases of urethral fistulas, no fistulas occurred.The success rate of operation was 95.9%. Conclusions The use of these techniques can reduce the incidence rate of urethrocutaneous fistulas in hypospadias repair and hypospadias fistulas repair.Based on our experience these techniques are the optimal repair for classical patients with hypospadias and hypospadias fistulas.

Objective To study the occurrence,risk factors,and direct economic losses caused by healthcare-asso-ciated infection(HAI)in hemodialysis patients in a hospital.Methods 840 patients who underwent hemodialysis in this hospital from April 2012 to September 2014 were selected,incidence of HAI,related factors,and economic los-ses due to HAI were investigated.Results Among 840 hemodialysis patients,89 patients developed 104 times of HAI,HAI density was 4.27‰ . Multivariate regression analysis showed that young age and old age,combined mul-tiple diseases,long duration of hemodialysis,two or more intubation sites,prolonged intubation,long length of hospital stay were all risk factors for HAI(OR= 1.123-2.325);Fees for bed,consultation,examination,treat-ment,nursing,medicine,and others in HAI group were all significantly higher than non-infected group(H= 49.6-1 038.9,all P<0.01 ),difference in medicine fees was most significant.Conclusion Risk factors for HAI are young age and old age,combined multiple diseases,long duration of hemodialysis,two or more intubation sites, prolonged intubation,and long length of hospital stay,the occurrence of HAI can increase the economic burden of hemodialysis patients.
