Inhibition of miR-148b ameliorates myocardial ischemia/reperfusion injury via regulation of Wnt/β-catenin signaling pathway.

Our work aims to elucidate the effect how microRNA-148b (miR-148b) participated in myocardial ischemia/reperfusion (I/R) injury via regulation of Wnt/β-catenin signaling pathway. The in vivo myocardial I/R models of SD rats and in vitro hypoxia/reoxygenation (H/R) models of H9C2 cells were established. The heart function and infarction area of rats and lactic dehydrogenase (LDH), creatine kinase (CK), malondialdehyde (MDA), and superoxide dismutase (SOD) levels were evaluated.

Research progress of photoperiod regulated genes on flowering time in rice.

Rice flowering regulation is an extremely complex process, which is controlled by genetic factors and external environment. Photoperiodic regulatory pathway is pivotal to control flowering in rice, in which florigen genes Hd3a and RTF1 are at the core and they are regulated by upstream Hd1-dependent, Ehd1-dependent, as well as both Hd1- and Ehd1-independent pathways. The three pathways bring a variety of light signal information together to Hd3a and RTF1 for further integration, and then transmit the signals in the form of florigen to the downstream flowering related genes.

[Evaluation of intraocular lens power after keratorefractive surgery by IOLMaster].

Objective: To study the accuracy of different formulas predicting intraocular lens (IOL) power after excimer laser keratorefractive surgery in order to calculate the diopter of IOL accurately in the clinical practice.

Methods: One hundred and eleven cases (222 eyes) were collected in this study and were divided into two groups (A and B) according to their axial length. Fifty-nine cases (118 eyes) with axial lengths of 24-26 mm were taken as group A, and 52 cases (104 eyes) with axial length of more than 26 mm were taken as group B.

[Simulation model on barley yield formation].

By the method of yield component, a simulation model on barley yield formation was established, which could be available for different barley cultivars in different areas. The establishment process of the model was as the following. With the yield components of different cultivars under optimal conditions in Wuhan, Yangzhou, and Kunming as the bases, the regression equations of the relative values of ears per plant, kernels per ears, and thousand-grain weight with the accumulated photosynthetic effective radiation (SigmaPAR) were established, and the functional relations between the ears per plant, kernels per ears, and thousand-grain weight under actual conditions as well as their potential values under optimal conditions and the variables soil moisture regime and nutrient contents under actual conditions were formed.
