?AlM: To study the correlation between monocular mild myopic juvenile myopia degree and dominant eye.
? METHODS: Totally 158 patients with juvenile monocularly mild myopia in our hospital from December 2012 to December 2013 were retrospectively analyzed, and cylindrical mirror astigmatism was used for spherical equivalent conversion. On the basis of the myopic degree, they were divided into three groups, 30 cases in group A (-0. 25~-0. 75D), 92 cases in B group (-1. 0~-2. 0D), 36 cases in group C (-2. 25 ~ -3. 0D). The card hole method was selected to measure dominant eye for subjectsat nearly 33cm and 5m. After glasses correction of ametropia, the far and near dominant eyes were received measurement again.
?RESULTS:The monocular mild myopia of dominant eye was compared with the non-dominant eye adjustment function, and there was no significant difference ( P>0. 05 ) . The dominant eye, non - dominant eye mean diopter and other correlations of eyes in the three groups were compared, and there was no significant difference (P>0. 05). The dominant eye of three groups at 5m was compared, and there was significant difference (P<0. 05). The dominant eye of three groups at 33cm was compared, and there was significant difference (P<0. 05). Dominant eye at different visual distance was compared, and there was significant difference (P<0. 05). Monocular uncorrected eye was compared with dominant eye mild afte myopia glassesr, and there was significant difference (P< 0. 05).
?CONCLUSlON: The formation of myopic anisometropia is related to the degree of clearly seeing objects, although glasses correction can improve the clarity and visual, but affect the choice of the dominant eye, because the myopic anisometropia appears most early in the dominant eye, therefore optician correction stage, which should be taken into consideration, and avoid the severity of the adolescent myopia.

Objective To assess the effect of anti- Helicobacter pylori (Hp) treatment on patients with chronic idiopathic thrombocytopenic purpura (cITP). Methods Fifty-nine patients with cITP and positive-Hp were divided into two groups by random digits table:Hp eradication group (30 cases,given a standard anti-Hp treatment) and placebo controlled group (29 cases,received a placebo). The platelet response of two groups was compared after three months' follow-up. Result The platelet response in Hp eradication group (63.3%, 19/30) was significantly higher than that in placebo controlled group (27.6%,8/29 )(χ2 = 7.59, P ＜ 0.05 ), and the increasing level of platelet count in Hp eradication group [ (33.5 ± 21.6)× 109/L] was higher than that in placebo controlled group [(12.6 ± 19.5) × 109/L] (t = 5.52,P ＜0.05).Conclusion Hp eradication treatment can promote the platelet recovery in mild and moderate cITP patients with positive-Hp.

High performance liquid chromatography-time-off-flight mass spectrometer (HPLC-TOFMS) technology coupled with partial least squares discriminant analysis (PLS-DA) processed by SIMCA-P software was applied to investigate serum endogenous metabolites alternations of valsartan in spontaneous hypertension rats (SHR). And MetPA platform was used to connect identified potential biomarkers in corresponding metabolic pathways to find possible therapeutic mechanism of valsartan. Valsartan significantly declined the blood pressure of SHRs (P < 0.05) at fourth week. The metabolic profiling significantly changed and four metabolites involved in G protein-coupled pathway were identified. Metabolomics is able to detect holistic and microcosmic alternations in organism, so as to elucidate therapeutic mechanism of drugs.

Purpose:To study the expression of CD44v6 protein in breast carcinoma and its prognostic significance. Methods:100 cases of formalin-fixed paraffin-embeded female breast invasive ductal carcinoma tissues were retrospectively analyzed using EnVision~(TM) immunohistochemical method with the monoclonal antibody CD44v6.Statistical analysis was based on the Log-rank test and Cox analysis.Results:Sixty-six of 100 cancer tissues expressed CD44v6.Positive staining was mainly on the cell membranes.There was significant correlation between CD44v6 immunoreactivity and lymph node me- tastasis and TNM stage.The 5-and 10-year survival rates were 82.76% and 78.37% of patients with CD44v6 low-expres- sion tumors,and 64.1% and 49.88% of those with CD44v6 high-expression tumors,respectively;the difference between the two groups of patients was significant(P

OBJECTIVETo observe the effect of β₃adrenoceptors (β₃-AR) activation on rat thoracic aorta smooth muscle contractility and the possible related mechanism.

METHODSThe endothelium removed thoracic aorta was pre-contracted with 30 mmol/L KCl physiological saline solution (PSS). Then the tension of the thoracic aorta was recorded in presence of BRL37344 (BRL) to determine the action of β₃-AR. The tension of the thoracic aorta was also recorded in the presence of Propranolol (PRA), SR59230A (SR), L-NNA, H-89 and Iberiotoxin (IBTX) respectively to reveal the underling mechanism of β₃-AR activation on rat vascular smooth muscle. Immunohistochemistry was adopted to confirm the existence and the distribution of β₃-AR in rat thoracic aorta.

RESULTSThe results showed that: (1) The thoracic aorta was relaxed by β₃-AR activation, with a relaxation percentage of (10.59 ± 0.79). (2) β₃-AR was expressed in both endothelial and smooth muscle layer in thoracic aorta sections of rats. (3) PRA did not block the effect of BRL on the thoracic aorta. The relaxation actions of BRL could be antagonized by pre-incubating the thoracic aorta with SR. (4) L-NNA (a NOS inhibitor) and H-89 (a PKA inhibitor) reversed the relaxation effect of BRL on vascular smooth muscle. (5) The effect of BRL was decreased after application of Ibriotoxin (IBTX), a large conductance calcium dependent potassium channel blocker.

CONCLUSIONThe results confirmed that activation of β₃-AR led to relaxation of thoracic aorta smooth muscle. The relaxation action of β₃-AR on smooth muscle of rat thoracic aorta was related to activation of NOS and PKA signaling pathway. Large conductance Ca²⁺-K⁺ channels were involved in the relaxation action of β₃-AR activation on rat thoracic aorta smooth muscle.

Abstract:Alcoholic liver disease (ALD) is one of the most common liver diseases in the world. Long-term alcoholism causes a series of pathological changes in the liver, which eventually leads to the occurrence of liver diseases with an increasing incidence. At present, significant progress has been made in the pathogenesis and pathological development of alcoholic liver disease, but the relevant mechanism of ALD has not been thoroughly studied. It is necessary to improve the existing animal model or establish a new, more comprehensive animal ALD model to simulate human ALD. Experimental animal models of ALD, especially rodents, are often used to simulate human ALD, and the ideal rodent ALD model can effectively simulate all aspects of alcohol in human liver. But so far, the commonly used animal models all have certain defects, and there is no complete animal model that can simulate human ALD. This paper reviewed the pathogenesis of ALD, related methods and influencing factors of ALD model, and provided a theoretical basis for relevant researchers to establish the ALD rodent model.
