Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

Objective To analyse effects of the serum levels of thyroid peroxidase antibodies (TPOAb) on antithyroid drugs (ATD) treatment in patients with incipient Graves disease (GD). Methods A total of 121 patients with incipient GD, who were used anti thyroid drugs for 12 months, were included in this study. Patients were dvided into two groups:TPOAb negative group (TPOAb≤35 IU/mL, n=49) and TPOAb positive group (TPOAb>35 IU/mL, n=72). According to the degree of TPOAb drops the TPOAb positive group was sub-divided into low level positive group (35 IU/mL1 000 IU/mL, n=20). The ATD total dosage for 12 months and thyroid-stimulating hormone (TSH), which returned to normal rate after treatment of 3, 6 and 12 months, were compared between groups. Results ATD total dose was lower in TPOAb positive group (1 743.82±265.38) mg than that of negative group (1 889.18 ±125.51) mg. The ATD total dosages were (1 759.71±230.29) mg, (1 793.75±299.02) mg, (1 731.54± 236.44) mg and (1 710.00 ± 290.73) mg for low level TPOAb positive group, medium level TPOAb positive group, high level TPOAb positive group, and very high level TPOAb positive group respectively. The recovering ratio of TSH was significantly higher in TPOAb positive group than that of TPOAb negative group after 3-month treatment (P<0.05). Conclusion TPOAb positive serum can lead to shorten the course of ATD treatment and reduce the total amount of ATD treatment in GD patients.

Objective To construct recombinant plasmids containing various functional domains of APC protein and detect their expression in HCT-116 cells. Methods Five APC gene fragments were amplified by PCR with whole APC gene as template and primers designed according to APC cDNA sequence and mutation cluster domain. The five obtained fragments were cloned into eukaryotic expression vector pEGFP-N3 to generate recombinant pEGFP-N3-APC1-5. Sequence of the inserted gene was identified and analyzed after restriction enzyme digestion. Liposome-mediated recombinant plasmid pEGFP-N3-APC was transfected into HCT 116 cells and identified by green fluorescence. RT-PCR was employed to validate the expression of recombinant vectors in cells. Results Recombinant pEGFP-N3-APC1-5 were confirmed by restriction enzyme digestion and sequence analysis. The plasmids could be expressed in HCT-116 cell line detected by fluorescence microscope. Results of RT-PCR made clear that vectors constructed could be expressed in HCT-116 cells. Conclusion The relative efficient expression of five recombinant expressive vector in HCT-116 cell line may provide an experimental basis for selecting specific therapy peptide for colorectal cancer.

Objective To investigate the relationship between abdominal aortic calcification (AAC) and outcomes in maintenance hemodialysis (MHD) patients. Methods One hundred and seventy MHD patients in the dialysis center of the Second Hospital of Tianjin Medical University from June 2014 and October 2014 were enrolled prospectively. Abdominal aortic calcification (AAC) was measured using AAC score (AACS) by abdominal lateral plain radiography. According to the AACS, the patients were divided into mild AAC (AACS<5) group and severe AAC (AACS≥5) group for comparison, and Kaplan?Meier analysis was used to compare their survival rates. Multivariable COX regression models were used to determine the risk factors of all?cause mortality and cardiovascular disease mortality in MHD patients. Results Severe AAC (AACS≥5) was present in 28.2%(48/170) patients. The median follow?up duration was 25.6 (22.0, 26.0) months. During the follow?up, 6 patients (4.9%) in AACS<5 group and 14 patients (29.2%) in AACS≥5 group died. Kaplan?Meier analysis showed that patients in AACS≥5 group had higher all?cause mortality rate and cardiovascular disease mortality rate as compared with patients in AACS<5 group (χ2=9.746 ,P=0.002; χ2=9.697 ,P=0.002). Multivariate COX regression analysis demonstrated that high AACS (HR=4.373, 95%CI 1.562?7.246, P=0.005) and hypoproteinemia (HR=0.886, 95%CI 0.797?0.985, P=0.025) were independent risk factors for all?cause mortality, while hypoproteinemia (HR=0.829, 95%CI 0.718?0.956, P=0.010) and low 1,25(OH)D3 (HR=0.769, 95% CI 0.627 ? 0.944, P=0.012) were independent risk factors for cardiovascular disease mortality. Conclusions AAC is significantly associated with overall survival in MHD patients. To further evaluate the relationship between AAC and outcomes in MHD patients, multi?center and long term follow up studies of large sample size are necessary.

Objective To assay the plasma omentin level in patients of type 2 diabetes mellitus (T2DM) combined with non-alcoholic fatty liver disease (NAFLD) and investigate the relationship between plasma omentin level,glucose and lipid metabolism,insulin resistance and NAFLD.Methods The plasma omentin level was assayed by enzyme-linked immunosorbent assay(ELISA) in all subjects,including patients of T2DM controls with NAFLD (group A,50 cases),T2DM without NAFLD (group B,50 cases),simple with NAFLD(group C,51 cases) and normal controls (group D,49 cases).Meanwhile,blood glucose,glycosylated hemoglobin(HbA1c),lipids and insulin levels were also measured.Body mass index (BMI) and waist-to-hip ratio were evaluated.Insulin sensitivity was assessed by HOMA-IR.Results The plasma omentin level was (17.85 ±3.68),(13.89 ±10.68),(26.05 ±7.26) and (22.92 ±2.71)μg/L in group A,B,C and D respectively.The plasma omentin level of group A and group B was significantly lower than that of group C and group D(P ＜ 0.05).The plasma omentin level of group A was higher than that of group B (P ＜ 0.05).The plasma omentin level of group C was higher than that of group D (P＜ 0.05).Correlation analysis showed that the plasma omentin level was negatively correlated to weight,BMI,waist,triglyceride,fasting blood glucose,fasting insulin (FINS) and HOMA-IR (P ＜0.05 or ＜0.01),and positively correlated to high-density lipoprotein cholesterol (HDL-C)(P ＜0.01).Multiple stepwise regression analysis showed that BMI,HOMA-IR and FINS was independent variable of omentin.The concentration of omentin was 24.82 μ g/L which could predict the risk of NAFLD in people with normal glucose regulation.Conclusions The plasma omentin level is closely correlated with glucose,lipid metabolism and insulin resistance.Plasma omentin may play an important role in the pathogenesis of T2DM and NAFLD.

Objective To study the urea rebound after hemodialysis in maintenance hemodialysis (MHD) patients and its impact factors. Methods From 124 stable MHD patients, blood samples were collected at the beginning, immediate post-hemodialysis, 15 minutes and 30 minutes after hemodialysis. The urea rebound was quantified, and its effect on URR and spKt/V was investigated. The impact factors on urea rebound were analyzed. Results In this group of patients, average post-hemodialytic urea rebound was 13.6%, leading to over-estimation of URR and spKt/V of 0.04 and 0.14, respectively. Hemodialysis efficiency expressed as K/V determined urea rebound most significantly. Other impact factors included higher hemoglobin, higher relative ultrafiltration, arteriovenous access, and male patients. Conclusions Urea rebound is common after the hemodialysis. For specific patients and hemodialysis sessions, ignoring it would result in significant over-estimation of delivered hemodialysis dose.

· Endoplasmic reticulum (ER) is a place where it folds and synthesizes the proteins.ER stress was induced when a variety of physiological and pathological factors happened,under which the protein misfolding occurred,the unfolded protein accumulated and the calcium ion imbalanced in the ER.The ER of high-glucose environment can change the protein redox state and produce reactive oxygen species,which affects the ER channel function and chaperone protein buffer;meanwhile changes the balance of calcium ions;finally induces the formation of ER stress.More and more studies have confirmed that ER stress in high glucose environment can cause a variety of ophthalmic diseases.So we review the recent articles about ER stress of high glucose environment and its related ophthalmic diseases.

Objective To characterize the changes in the dimensions during systolic and diastolic periods in the aorta with ECG-gated multi-detector CTA scans.Methods The CT angiograms of 115 patients (78 males,mean age 55.2 ± 9.4 years;37 females,mean age 60.1 ± 8.5 years) both in systolic and diastolic periods were obtained on a 64-slice ECG-gated multi-detector CT scanner.The diameters were measured at four anatomic levels of the aorta.(Level A:1 mm proximal to the innominate artery;Level B:1 mm distal to the left common carotid artery;Level C:1 mm distal to the left subclavian artery;Level D:10cm distal to the left subclavian artery).On each level,the maximal and the minimal diameters were measured both in systolic and diastolic periods.Results The paired sample t test results showed a significant difference between the systolic and diastolic diameters in all individual subjects on every level (P ＜0.001).The mean maximum diameter changes were 1.95％ (range-2.0％ to 7.0％),2.12％ (range-3.0％ to 6.0％),1.88％(range-1.0％ to 8.0％)and2.47％(range-3.0％ to 10.0％)at level A,B,C and D,respectively.The mean minimum diameter changes were 1.43％ (range-3.0％ to 5.0％),2.67％ (range-2.0％ to 11.0％),1.75％ (range-14.0％ to 9.0％)and 2.99％ (range -2.0％ to 11.0％) at level A,B,C and D,respectively.Conclusions The differences of the aortic diameters between systolic and diastolic periods are significant.The pulsatility of aorta in Chinese population may be different from published Western literature.
