With the development of corneal refractive surgery, especially the application of femtosecond laser, and the lack of corneal donor, corneal stromal lenticules produced in refractive surgery have gradually attracted the attention of ophthalmologists.Most fresh corneal stromal lenticules are difficult to put into use immediately, so how to better preserve and treat the lenticules is a problem that ophthalmologists need to solve.Corneal stromal lenticules can be used in the treatment of many kinds of ophthalmic diseases.In this article, the preservation and treatment of corneal stromal lenticules, as well as its application and prospects in treating hyperopia and presbyopia, keratoconus, corneal ulcer, corneal dystrophy, dermoid tumors and recurrent pterygium, corneal thinning after laser in situ keratomileusis, and covering glaucoma drainage valve to prevent exposure were reviewed to provide reference for further clinical research and application.

OBJECTIVETo explore the effect of electroacupuncture (EA) on the expression of Ghrelin and mRNA expression of its receptor in functional dyspepsia (FD) rats.

METHODSTotally 80 rats were divided into the normal group, the model group, the drug therapy group, and the EA group according to random digit table, 20 in each group. FD model was duplicated by clipping tail modeling. Drug containing cisapride [2 mL/100 g, 0.09 g/(kg x d)] was administered to rats in the drug therapy group from the 3rd day after successful modeling, once per day. EA at Zusanli (ST36) (0.3-0.5 cun) and Taichong (LR3) (0.1-0.2 cun) was performed in the EA group. The twirling of needle was performed to the subsidence of needle, and then the needle was connected to HANS-200A Acupoint Nerve Stimulating Device using disperse-dense wave at 2 Hz, 2 mA, 30 min each time, once per day. Six days consisted of one therapeutic course, two courses in total with an interval of one day. The intestinal propulsive rate of ink was observed. Ghrelin protein expression in gastric tissue was detected by Western blot. mRNA expression of growth hormone secretagogue receptor (GHS-R) in stomach, hypothalamus, and hippocampus was detected using Real-time PCR respectively.

RESULTSCompared with the normal group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus decreased in the model group (P < 0.05, P < 0.01). Compared with the model group, the intestinal propulsive rate of ink, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the EA group (P < 0.01); mRNA expression of GHS-R in stomach, hypothalamus, and hippocampus increased in the drug therapy group (P < 0.01). Compared with the drug therapy group, Ghrelin protein expression in gastric tissue, mRNA expression of GHS-R in hypothalamus increased in the EA group (P < 0.05, P < 0.01).

CONCLUSIONEA could regulate Ghrelin content and GHS-R mRNA expression of FD rat hypothalamus, hippocampus, and gastric tissue, and promote the intestinal propulsive rate of ink.

Objective To develop a non-invasive method for diagnosis of esophageal varices in patients with cirrhosis induced by viral hepatitis.Methods The clinical data,including results of blood routine,liver function,blood coagulation and color ultrasonography,of patients with cirrhosis induced by viral hepatitis from the First Affiliated Hospital of Zhengzhou University during December 2011 and December 2012 were retrospectively analyzed.Patients with hematopoietic diseases and portal vein thrombosis were excluded,and no patients received beta-blocker,endoscope band ligation,and splenectomy treatment.According to gastroscopic results,all patients were divided into no/mild group and mid/serious group.Correlations between clinical data and esophageal varices were analyzed by Logistic regression method,and receiver operating characteristic (ROC) curve was used to evaluate their values for diagnosis of esophageal varices.Results Totally 96 patients were enrolled in the study,30 without or with mild esophageal varices,and 66 with mid/serious esophageal varices.There were significant differences on platelet (PLT),plateletcrit (PCT),platelet distribution width (PDW),alanine aminotransferase (ALT),aspartate aminotransferase (AST),spleen thickness (ST) and PLT/ST between no/mild group and mid/ serious group (Z/t =-2.842,-3.151,-2.549,-3.463,-3.601,-4.360and 11.877,P＜0.05 or P ＜ 0.01).Multivariate logistic regression analysis showed that only ST was statistically different between two groups (OR =1.127,OR 95％ confidence interval (CI):1.012-1.256,P =0.030).The area under the curve (AUC) was 0.728,and 95％ CI:0.628-0.827.With the cut off value of 52.5 mm,the sensitivity,specificity,and Youden index of ST in diagnosis of esophageal varices were 53.0％,90.0％ and 0.43,respectively.Conclusion ST measured by color ultrosonography can be used for early diagnosis of mid/serious esophageal varices.

Objective To investigate the role of nucleotide-binding oligomerization domain-containing protein 1 (NOD1) in inducing insulin resistance in differentiated human adipocytes.Methods Human preadipocytes obtained via liposuction were induced to differentiate into mature adipocytes.iE-DAP,a specific ligand for NOD1,was administered to human adipocytes in culture.NF-κB transcriptional activity and proinflammatory cytokines production were determined by luciferase assay and enzyme-linked immunosorbent assay.Glucose uptake in adipocytes was measured by 2-deoxy-D-[3 H] glucose uptake (P＜0.05).The expression of phosphatidylinositol-3-kinase p85 (PI-3K p85),insulin receptor substrate-1 (IRS-1) and Akt phosphorylations were detected by Western blotting.Results NF-κB transcriptional activity and cytokines such as interleukin (IL)-6,IL-8,and monocyte chemotactic protein 1 secretion were markedly increased after stimulation with iE-DAP (P＜0.05 or P＜0.01).Insulin-induced glucose uptake was decreased with the activation of NOD1 in a dose-and time-dependent fashion.NOD1 activation weakened insulin signal transduction as being revealed by increasing IRS-1 Ser307phosphorylation,reducing protein expression of PI-3K p85,and attenuating insulin-induced phosphorylation of Akt on Ser473 and Thr308in human adipocytes.Conclusion These results indicate that NOD1 activation induces inflammatory response and insulin resistance via IRS-1/PI3-K/Akt signaling pathway in human adipocytes.
