Objective To preliminary investigate the brain areas associated with Chinese when they speak Chinese . Methods In order to determine the neural anatomic substrates employed in repeatedly speaking Chinese , 22 Chinese health volunteers were performed using blood oxygenation level dependent (BOLD) contrast functional magnetic resonance imaging (fMRI) on a 1.5T system .Results Our block-design fMRI studies have found many cortical areas that are associated with Chinese-English bilinguals. The cortical areas were shown as bilateral motor cortex , left anterior inferior frontal Gyrus , left anterior insula , bilateral superior temporal gyrus and bilateral cerebellum. Conclusion BOLD fMRI can reveal cortical areas that are associated with Chinese when they speak Chinese ,and it is a powerful utility to investigate language.

Objective To study the changes of the myocardial cell apoptosis in myocardial infarction of rabbits. Methods The model of rabbit with myocardial infarction was established.HE staining,TUNEL staining, immunohistro-chemistry staining, ultrathin section for electron microscope and DNA electronic gel phorensis were performed in samples of ischemia or infarction in different times.The position of apoptotic myocytes in different phases of ischemia were observed by light microscope and electronic microscope. Results After 30 minutes to 4 weeks ischemia.there were a few TUNEL positive nucleus of myocytes in the margin area of myocardial infarction;HE staining-found typical expressions of apoptosis,such as chromosome conglomeration,chromosome gathered at the edge or chromosome aggregation,dark-stained nucleus,cell shrinkage,were obvious in 4-8 hours.A lot of positive nucleus of myocytes stained by TUNEL were found in the early stages of myocardial ischemia in myocardial infarction.gradually ascended and then became hardly visible from 8 hours to 3 days.Nucleus swelling,karyorrhexis and karyolysis were found in the area of myocardial infarction.then cells were broken.DNA agarose electrophoresis found DNA fragment of most myocytes in 30 minutes of ischemia,just a few cardiocytes decomposed to the big segments.At 4hours of ischemia the most cardiocytes decomposed to big segments,and there were a blurry"ladder"in DNA strand breaks from 8 hours to 1 day.It showed that apoptotic cardiocytes existed in the margin area of myocadial infarction. Conclusions There are cardiocytes apoptosis in the margin area of infarction from 30 minutes to 4 weeks after myocardial ischemia.Maybe it relates to the reperfusion caused by collateralization establishment or infiltration from circumference.

Motor neuron disease(MND) is a group of progressive motor neuron diseases and the pathogenesis is not well defined.The pathologic hallmark of MND is death of lower motor neurons(consisting of anterior horn cells in the spinal cord and their brainstem homologues innervating bulbar muscles) and upper, or corticospinal, motor neurons.The clinical manifestations of MND are mucsle weakness, muscle atrophy, fasciculations, bulbar paralysis and positive pyramidal signs.Traditional Chinese medicine(TCM) named MND as flaccidity syndrome.Recently, some scholars have proposed that "MND" can be regarded as an independent research object of TCM.At present, symptomatic supportive treatment is the main treatment for MMD in western medicine, which can only slow the progress of the disease.TCM treatment for MND has advantages of more effective than western medicine, fewer adverse reactions and lower price.So TCM can be used as an effective method for combined treatment of MND.This article reviews the research progress of syndrome and treatment of MND with TCM.

Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty, which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas(The Second Batch of Pediatrics) released by the National Administration of Traditional Chinese Medicine(TCM) in September 2022, and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature, this study conducted herbal textual research on Yigongsan from five aspects, including historical evolution, origin and processing, dosage conversion, usage and preparation methods, and functional application, then formed the key information table of this formula, in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study, it is recommended that Panax ginseng should be removed the basal part of stem(rhizoma), Poria cocos should be removed the peel, Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian(钱), 1 g/slice for ginger, 3 g for each jujube and 300 mL/Zhan(盏), the doses of Ginseng Radix, Poria, Atractylodis Macrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Citri Reticulatae Pericarpium, Zingiberis Rhizoma Recens, Jujubae Fructus were 1.652, 1.652, 1.652, 1.652, 1.652, 5, 6 g, and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh, add 300 mL of water and decoct to 210 mL for each dose, then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach, and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians, and is often used to treat anorexia, inflammation of the digestive tract, diarrhea and other diseases in children.

ObjectiveTo establish the fingerprint of seven commercially available Yangyin Qingfei preparations, to quantitatively analyze the index components, to evaluate their quality uniformity with multivariate statistical analysis, and to explore the quality differences among different dosage forms. MethodA total of 33 batches of commercially available 7 kinds of Yangyin Qingfei preparations were analyzed by high performance liquid chromatography(HPLC), the fingerprints were established and the common peaks were identified. Paeoniflorin, verbascoside, harpagoside, glycyrrhizic acid and paeonol were selected as the indicators of quality attributes to quantitatively analyze 33 batches of preparations. Based on the administration methods of Yangyin Qingfei preparations, the daily intake was calculated and the radar charts were poltted, and cluster analysis and principal component analysis were used to explore the quality differences of 7 kinds of Yangyin Qingfei preparations and the quality uniformity among different batches of the same dosage form. ResultThe similarity of fingerprints of 7 dosage forms was 0.248-0.956, suggesting that there were significant differences among different dosage forms of Yangyin Qingfei preparations, and a total of 15 common peaks were calibrated, of which peak 7, peak 8, peak 11, peak 13 and peak 15 were paeoniflorin, verbascoside, harpagoside, glycyrrhizic acid and paeonol, respectively. The radar plots showed that the average total daily intake of large honeyed pills and water honeyed pills was the highest, and the uniformity of pill components was better. The quality of 33 batches of samples was divided into poor quality and high quality by cluster analysis. Principal component analysis showed that the uniformity and dosage form of different dosage forms were significantly different, the oral liquid had the best quality homogeneity with the minimum dispersion. And the content of paeonol in different dosage forms was significantly different, which was the key component of quality control of Yangyin Qingfei preparations. ConclusionYangyin Qingfei large honeyed pills and water honeyed pills show high content and good uniformity, which are relatively preferred dosage forms. Different preparation processes have a great influence on the content of paeonol, and its quality control should be emphasized during production. This study provides a scientific method for the comparison of product quality of different dosage forms of traditional Chinese medicine prescriptions, which is helpful for the development of preferred dosage forms of different prescriptions, and provides a reference for efficient use of medication in the clinical practice.
