AIM:To compare the effect of three types of pterygium surgery and on tear film in patients with type 2 diabetes mellitus. ·METHODS:A total of 102 patients ( 102 eyes ) with pterygium combined with type 2 diabetes mellitus treated in our hospital from March 2013 to March 2016 were analyzed retrospectively. The patients were divided into three groups including the 34 cases ( 34 eyes ) with simple excision of pterygium ( resection group ) , pterygium excision combined with conjunctival flap transplantation in 34 cases (34 eyes, as conjunctival flap group ) and pterygium excision combined with limbal stem cell transplantation in 34 cases ( 34 eyes, as stem cell group ) . The wound repair time, complications, recurrence rate, uncorrected visual acuity (UCVA), tear film break-up time ( BUT ) and basal tear secretion test (SⅠt) were observed before, and 6 and 12mo after surgery in the three groups, respectively. ·RESULTS:The postoperative UCVA of the three groups was significantly higher than that preoperation ( P =0. 039, 0. 013, 0. 024 ), and there was no significant difference among the three groups ( P = 0. 317 ). The wound repair time was 5. 67 ± 1. 45d in the resection group, which was significantly higher than that in the conjunctival flap group (4. 18 ± 0. 76d) and the stem cell group (4. 09±0. 79 d) (P<0. 001), there was no significant difference between the conjunctival flap group and the stem cell group ( P = 0. 937 ). There were 4 cases in resection group reappeared, and the recurrence rate was 11. 8%, which was significantly higher than the other two groups ( P = 0. 037 ). There were 1 recurrences in the conjunctival flap group, and the recurrence rate was 2. 9%, while the patients in the stem cell group had no obvious recurrence. SⅠt and BUT increased significantly after operation (P<0. 05), especially in conjunctival flap group and stem cell group (P<0. 001). There was no significant difference between the conjunctival flap group and the stem cell group (P=0. 845, 0. 894). · CONCLUSION: Pterygium excision combined with conjunctival flap transplantation or limbal stem cell transplantation for the treatment of type 2 diabetic patients with normal blood glucose and tear film function has the similar effect, and is better than simple pterygium excision.

AIM: To evaluate the clinical outcomes of combined wavefront - guided and aspheric laser in situ keratomileusis ( LASIK ) to correct myopia and myopic astigmatism.
METHODS: Prospective study. Forty-five patients ( 62 eyes ) with myopia and myopic astigmatism were randomly dividied into two groups:the wavefront-guided and aspheric LASIK group and the wavefront- guided LASIK group. Safety, efficacy, predictability, ocular higher order aberrations(HOAs), and contrast sensitivity under mesopic condition were compared at 6mo postoperatively.
RESULTS: Both platforms had equal safety, efficacy and predictability. At 6mo after operation, total HOAs, spherical aberration and coma increased in both groups(P<0. 01 ). The changes of total HOAs and spherical aberration in wavefront-guided and aspheric group were significantly less than those in wavefront-guided group ( P<0.05 ) , while the change of coma between two groups was not statistically significant ( P = 0. 657 ). Contrast sensitivity in the wavefront-guided and aspheric group recovered to preoperative levels under mesopic conditions at all spatial frequencies ( P > 0. 05 ), while contrast sensitivity in the wavefront-guided group recovered to preoperative levels at all spatial frequencies(P>0. 05).
CONCLUSION: Wavefront-guided and aspheric LASIK induced less HOAs and associated with better mesopic contrast sensitivity compared with wavefront - guided LASIK.

Objective To investigate the factors for retinopathy in premature infants. Methods Ophthalmologic mydri was conducted in premature infants and acording to the international classification of ROP, they were diagnosed as ROP. The risk factors of the incidence of ROP were statistically and respectively analyzed. Results Among total of 47 patients, 11 patients were found retinopathy of prematurity. Conclusion The body weight is lower, the gestation is shorter, incidence of ROP is the higher.

Sleep quality is closely related to human health. It is very important to correctly discriminate the sleep stages for evaluating sleep quality, diagnosing and analyzing the sleep-related disorders. Polysomnography (PSG) signals are commonly used to record and analyze sleep stages. Effective feature extraction and representation is one of the most important steps to improve the performance of sleep stage classification. In this work, a collaborative representation (CR) algorithm was adopted to re-represent the original extracted features from electroencephalogram sig- nal, and then the kernel entropy component analysis (KECA) algorithm was further used to reduce the feature dimension of CR-feature. To evaluate the performance of CR-KECA, we compared the original feature, CR feature and readied CR feature (CR-PCA) after principal component analysis (PCA). The experimental results of sleep stage classification indicated that the CR-KECA method achieved the best performance compared with the original feature, CR feature, and CR-PCA feature with the classification accuracy of 68.74 +/- 0.46%, sensitivity of 68.76 +/- 0.43% and specificity of 92.19 +/- 0.11%. Moreover, CR algorithm had low computational complexity, and the feature dimension after KECA was much smaller, which made CR-KECA algorithm suitable for the analysis of large-scale sleep data.

In recent years the interaction between host and gut microbiota has attracted increasing attention. However, intestinal flora dysbiosis may lead to many diseases, and there is increasing evidence that the intestinal microbiota in patients with chronic kidney disease (CKD) is associated with the pathophysiological status of the host. "Gut-kidney axis" provides a better explanation of the two-way communication between intestinal flora and CKD. Impaired kidney function leads to dysbiosis of intestinal flora and an altered intestinal flora can damage the intestinal mucosal barrier and facilitate the entry into the bloodstream of harmful bacteria, which can induce chronic inflammation and thus accelerate renal injury. In addition, the accumulation of nephrotoxic metabolites from an altered intestinal flora can aggravate CKD in the "gut-kidney axis". Among them, p-cresol sulfate, indoxyl sulfate and trimethylamine oxide are the most widely studied metabolites of nephrotoxicity, and their renal toxicity has been widely confirmed in basic research and clinical studies. Current studies show that the intestinal microbiota-metabolite network is closely related to the occurrence and development of chronic kidney disease. Thus, intervention in the intestinal microbiota may provide a new approach to the prevention and treatment of chronic kidney disease.
