This study makes a comparison between China and foreign countries about the ＂supportive shipping policies＂ in the period of late qing Dynasty, from 1840 to 1911. After the first opium war, China was forced to open the gate of the old oriental country to the world. As more treaty ports opened, the import and export of goods increased the growing trade that brought about the increased demands of shipping transportation. In the same period, British, France, America, Germany and Japan governing bodies instated various kinds of laws, regulations and other policies encouraging their national shipping companies to grab shipping market share. As a result, foreign steamship companies monopolized Chinese shipping market quickly. Faced with this situation, in 1872, the China Merchants＇ Steam Navigation Company was the fisst steamship company of China to be formed. It was a government-supervised and merchant-managed company, and the qing Dynasty government took a series of measures to support it under the fierce competition, these measures were different from foreign countries＇.

AIM To observe the changes in oxygen free radical (OFR) and the curative effect of traditional Chinese medicine 'qing Yi Tang' in acute necrotizing pancreatitis (ANP).METHODS After induction of ANP by injection of sodium taurocholate into pancreatic duct, 16 dogs were randomly divided into control group and Chinese medicine group. Serum amylase, SOD and MDA were determined on postoperative day 1, 2, 4 and 7. The animals were sacrificed on day 7. SOD and MDA in organs were determined, and pathological changes in pancreas were *** As compared with control group, the serum level of amylase (734U/L vs 2783U/L) and MDA (7.8nmol/ml vs 14.8nmol/ml) in Chinese medicine group were decreased on day 7 (P＜0.05), while SOD increased significantly (281nU/ml vs 55nU/ml, P＜0.01), and similar changes occurred in MDA and SOD in organs, especially in the pancreas; the pathological changes in the pancreas were alleviated as *** 'qing Yi Tang' is effective in clearing OFRs and alleviating pathological changes in ANP.

The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u

This study aimed to investigate the effect of varying pyrite(Py)content on copper(Cu)in the presence of different regrinding conditions,which were altered using different types of grinding media:iron,ceramic balls,and their mixture,followed by flotation in the cleaner *** flotation performance of rough Cu concentrate can be improved by changing the regrinding conditions based on the Py *** electron microscopy,X-ray spectrometry,ethylenediaminetetraacetic acid disodium salt extraction,and X-ray photoelectron spectroscopy studies illustrated that when the Py content was high,the use of iron media in regrinding promoted the generation of hydrophilic Fe OOH on the surface of Py and improved the Cu *** ceramic medium with a low Py content prevented excessive Fe OOH from covering the surface of chalcopyrite(Cpy).Electrochemical studies further showed that the galvanic corrosion current of Cpy-Py increased with the addition of Py and became stronger with the participation of iron media.
