Clinical efficacy research of nerve growth factor combined with traditional medicine for the treatment of anterior ischemic optic neuropathy
AIM: To evaluate the efficacy and safety of nerve growth factor(NGF)on optic nerve anterior ischemic optic neuropathy.<p>METHODS:A total of 343 eyes of 343 patients with anterior ischemic optic neuropathy were treated with mouse NGF by the dosage of 30μg qd and continuous injected for three weeks, at the same time given expanding vascular medicine and neurotrophic agent. Corrected LogMar visual acuity, visual field mean deviation(MD)values and pattern visual evoked potential(P-VEP)were recorded and analyzed. The adverse reactions in the course of treatment were analyzed in order to evaluate the safety of this method. <p>RESULTS: The patient's vision after treatment were significantly increased compared with that before treatment, MD of visual field and P-VEP display incubation period after treatment were significantly lowered compared with that before treatment, the difference were statistically significant(<i>P</i><0.05). There were 18 cases of adverse events in laboratory indicators in this study, and the incidence rate was 5.25%.<p>CONCLUSION: Mouse nerve growth factor combined with vasodilators and neurotrophin for the treatment of anterior ischemic optic neuropathy had satisfaction efficacy and safety
Protecting entanglement from correlated amplitude damping channel using weak measurement and quantum measurement reversal
Based on the quantum technique of weak measurement, we propose a scheme to
protect the entanglement from correlated amplitude damping decoherence. In
contrast to the results of memoryless amplitude damping channel, we show that
the memory effects play a significant role in the suppression of entanglement
sudden death and protection of entanglement under severe decoherence. Moreover,
we find that the initial entanglement could be drastically amplified by the
combination of weak measurement and quantum measurement reversal even under the
correlated amplitude damping channel. The underlying mechanism can be
attributed to the probabilistic nature of weak measurements.Comment: 11 pages, 5 figures, accepted by Quantum Information Processin

Investment by Chinese construction firms in the UK infrastructure sector: volumes, patterns and trends
The expansion of global construction markets has substantial implications for companies engaged in cross-border transactions and financing. The convergence of
the UK and the People’s Republic of China (PRC) infrastructure policy agendas has led to significant investment from Chinese construction companies in the UK
infrastructure sector. On the demand side, the UK Government’s National Infrastructure Plan sets out a wide range of investment priorities. The PRC Government’s One Belt, One Road strategy, on the supply side, has prioritized
outward foreign investment into Eurasia. The international business literature on foreign market entry with a specific organizational capability perspective is drawn upon to understand the rationale for Chinese construction companies to invest in the UK infrastructure market. Two Chinese construction multinational companies currently engaging in UK infrastructure projects are studied through interpreting
secondary sources. Findings indicate that their pursuit of hybrid market entry modes are underpinned by corresponding hybrid capability exploitation and acquisition motivations
2-Bromo-1-(4-methoxyphenyl)ethanone
The title compound, C9H9BrO2, prepared by the reaction of 4-methoxyacetophenone and cupric bromide, , is approximately planar (r.m.s. deviation 0.0008 Å). In the crystal, weak intermolecular aromatic C—H⋯Ocarbonyl hydrogen-bonding interactions result in a one-dimensional chain structure
2,2′-Hexamethylenedi-1,3-benzothiazole
The title compound, C20H20N2S2, was prepared by the reaction of suberic acid and 2-aminothiophenol under microwave irradiation. The molecule lies on an inversion center
