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 investigate early nasogastric nutrition on patients with acute decompensated chronic heart failure,and observe its influence on patient's disease outcome.Methods From January 2012 to December 2013,100 cases with acute decompensated chronic heart failure were used as the research subjects,were randomly divided into experimental and control groups with 50 cases each group.Patients of two groups adopt expansion of blood vessels,strong heart,diuresis,and routine anti-infection treatment;Based on this scheme,experimental group adopt early nasogastric nutrition.The cardiac function index,the change of nutritional status and clinical curative effect and the result of follow-up within 1 year after discharge of two groups were compared.Results Left ventricular end-diastolic dimension (LVEDD) and left ventricular end-systolic dimension (LVESD) in two groups after treatment were decreased,and the descender of experimental group was superior to that of the control group with statistically significant difference (P ＜ 0.05).After treatment,left ventricular ejection fractions (LVEF) of two groups were improved,and the rise of experimental group was superior to that of control group with statistically significant difference (P ＜0.05).In the two groups after treatment,the serum brain natriuretic peptide (BNP) levels were significantly decreased,and the descender of the experimental group was more than that of control group with statistically significant difference (P ＜ 0.05).After treatment,body mass index (BMI),the level of serum prealbumin (PA),transferrin (TRF),and the total number of lymphocytes of two groups were increased significantly (P ＜ 0.05);and BMI,the level of serum PA and TRF,and the total number of lymphocytes of the experimental group were significantly better than those of the control group (P ＜ 0.05).The total effective rate of the experimental group was significantly higher than that of the control group (P ＜ 0.05).The exacerbation rates,readmission and mortality rate of experimental group follow-up within 1 year after discharge were significantly lower than that of the control group (P ＜ 0.05).Conclusions The early nasogastric nutrition on the patients with acute decompensated chronic heart failure was better able to improve patients' nutrition state,more conducive to patients with cardiac function recovery,improve the clinical curative effect,and reduce the exacerbation rates,and readmission and mortality rate.

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.

Premature ejaculation (PE) is a most common sexual dysfunction, for which dapoxetine, a novel selective serotonin (5-HT) re-uptake inhibitor (SSRI), is the only licensed oral medicine at present. With the advantages of fast absorption, rapid action, on-demand medication, and short half-life time, dapoxetine has been proved by clinical trials to be effective in prolonging the intravaginal ejaculation latency time (IELT) and improving the overall condition of PE patients in various areas and populations. Compared with the traditional SSRIs, dapoxetine has a better safety and tolerability. The most frequently reported dapoxetine-related adverse events include nausea, diarrhea, headache and dizziness, but with very few severe or serious cases.

The pathologic grading and clinical staging systems have some restrictions for the evaluation of the prognosis of prostate cancer.Early detection of prostate cancer with clinically sensitive diagnostic methods and / or tumor specific markers is of prime importance.Recently,close attention has been paid to the effects of genes related to apoptosis and tumor suppressor genes on the development,progression and prognostic value of prostate cancer.The importance of enzymes/proteins and hormone receptors have also received more and more emphasis in the studies of prostate cancer.

Objective: To study the nature and flavour of LIU Wan-su’ drug application and the tendency of cold or warm in his prescription; analyze LIU Wan-su’s medical sect by the index of prescription metrology. Methods: Combining the traditional documents with prescription metrology, selecting three doctors before or after LIU Wan-su in Jin and Yuan Dynasty as comparison to expose the characteristic of prescription metrology in his prescription. Results: Wen tonic frequency of each prescription on average, LI Dong-yuan(1.10),ZHU Dan-xi(0.97), LIU Wan-su (0.77), ZHANG Zi-he(0.65); Han tonic frequency of each prescription, LI Dong-yuan (1.34),ZHANG Zi-he (1.00), LIU Wan-su (0.94), ZHU Dan-xi(0.80);Cool and warm drug ratio of four sects in Jin and Yuan Dyanstay, ZHU Dan-xi (0.97),LI Dong-yuan(0.83), LIU Wan-su (0.82), ZHNAG Zi-he (0.58).Cool and warm prescription ratio, ZHANG Zi-he(1.50), LIU Wan-su (0.87), LI Dong-yuan(0.76), ZHU Dan-xi (0.50).Conclusion: As the exponent of "theory of fi re and hot", it will be better to classify LIU Wan-su as " Hejian sect" since his drug application was not limited within cold and cool. To some extent, it is more important to judge a Chinese traditional doctor by syndrome identifi cation rather than only by his drug frequency.
