The corrdlations between the total score of ASRSYC and the subtest scores of C - WYCSI ranged from 0. 51 to 0. 75 . Conclusion Adaptive skills and intelligenoe in young children relate each other and develop jointly.

This study was aimed to determinate the content of quercetin from different parts (such as flowers, fruits, stems, leaves and branches) of Penthorum chinense Pursh. from Sichuan province so as to offer reference for the comprehensivedeve lopment and utilization of P. chinense Pursh. The quantitative determination of quercetin from five groups of different parts of P. chinense Pursh. were carried out and put into comparison by the reversed-phase high performance liquid chromatography (RP-HPLC). The results showed that there were larger differences of content among different parts. The highest content of the medical parts were flowers and fruits, which was followed by the leaves, stems and branches. It was concluded that different parts (such as flowers, fruits, stems, leaves and branches) of P. chinense Pursh. from Sichuan province should be divided in the clinical and productive practice, which was to supply the scientific basis for enhancing the curative effect and reasonable exploitation and utilization of the resource of P. chinense Pursh.

OBJECTIVE To explore optimal change dressing of the incision of trachea.METHODS Seventy-eight patients were randomly and equally divided into the traditional group and test group.In traditional group,after dressings change with conventional disinfection,the sterile gauze was cut into "E" shape and overlapping covered on the incision of trachea around the trachea cannula from top to bottom and fixed with adhensive plaster.In test group,after dressings change with conventional disinfection,the special sterile drainage was fixed and smoothed around the trachea cannula from left to right(or from right to left).RESULTS In test group,skin incision colonies of patients were significantly lower than that in traditional group(P

The human bronchial arteries and their anastomoses with pulmonary vessels were studied on normal and diseased lungs in 30 adult and infant cadavers under a magnification of 3～40 times.The bronchial arteries pursue a tortuous serpentine course along the surface of the bronchi. They divide either before or after the bifurcation of the bronchi and often send two branches coursing along each bronchus with one branch on each side of the bronchial wall. These branches usually form a network in the fibrous coat of the bronchus. Smaller twigs penetrate the bronchial walls and form a similar network in the submucosa.Mediastinal pleural branches and interlobar pleural branches of the bronchial arteries have their subpleural, independent course from the bronchial tree and their larger caliber at peripheral sites.In the visceral pleura and on the surface of the bronchi or within the bronchial wall, there are precapillary anastomoses between the bronchial and pulmonary arteries, and between the bronchial artery and pulmonary veins. The anastomoses occur either end to end or end to side.In the pleural adhesions of 9 cases of the lungs, the newly developed pleural branches arising from the intercostal, the superior intercostal, the pericardiophrenie or the internal mammary artery, anastomose with the bronchial artery via pleural arterial network to reinforce the blood supply for the diseased pulmonary area.The important physiological function of the anastomoses between the bronchial arteries and pulmonary vessels, as well as the course and distribution of the bronchial arteries in the lungs were discussed.

Objective To investigate the clinical diagnostic value of electrocardiogram(ECG)in patients with low blood potassium.Methods From January 2015 to October 2015,patients with low blood potassium were given ECG examination in Yueqing Maternal And Child Health Care Hospital.The relationship between low blood potassium and ECG changes was analyzed.Results The concentration of serum potassium in patients with 0.9 -2.5mmol/L electrocardiogram U wave change,T wave change,ST segment changes,Q -T prolongation,arrhythmia were significantly higher than that of serum potassium concentration in 2.6 -3.4mmol/L patients,and the difference was statistically significant (χ2 =4.63,4.10,4.47,5.01,4.92,all P <0.05).Of patients with hypokalemic ECG showed characteristics of U wave amplitude increased,ST segment depression,T wave amplitude decreased,QT interval prolongation,arrhythmia,of which the most common was premature ventricular contractions,severe low blood potassium could also be occurrence of malignant ventricular arrhythmia.Conclusion Low blood potassium has characteristic changes of ECG,ECG as a noninvasive,simple and quick examination,which is helpful for the rapid diagnosis of low blood potassium.

OCT angiography (OCTA) is a non-invasive imaging technique for detecting blood flow information of the retina and choroid.Dye injection is not needed with OCTA,which is different from fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA).OCTA is able to observe blood flow in different retinal and choroidal segmentation slab.This revolutionary breakthrough in OCTA algorithm provides more and more accurate blood flow informations in the diagnosis of ocular vessel diseases and the study on pathogenesis of some vessel-related eye diseases.However,like other biometric technology,OCTA has its limitations and shortcomings,for example,OCTA presents a smaller observational area than FFA and ICGA,and some factors affect the imaging quality and cause misdiagnosis during the examination and reading image.Fully understanding the principle of OCTA and its image features are helpful for eye doctors to better interpret the blood flow changes of retinal diseases,choroidal diseases,glaucoma and neuro-ophthalmic diseases.Ophthalmologists should correctly apply this imaging tool for a better monitoring and following up of these diseases.

The afferent connections to the nucleus amygdaloideus centralis and nucleusamygdaloideus medialis in 42 albino rats were examined by means of retrogradetransport method of horseradish peroxidase(HRP).The microinjection syringe needle or microelectrophoretic pipette was insertedstereotaxically from vertical or oblipue approaches.The injections of HRP weregiven in the central and medial nuclei of the amygdaloid complex.The results were as follows:Following the injections of HRP into the nucleus amygdaloideus centralis,label-ed cells were always found in prepiriform cortex,periamygdaloid cortex,entorhinalcortex,ventral part the caudoputamen and globus pallidus,nucleus lateralis hy-pothalami,nucleus parafascicularis,corporis geniculati medialis,nucleus raphe dosalis,nucleus parabrachialis,locus coeruleus and zona reticulate substantia nigra.While HRP was injected into the nucleus amygdaloideus medialis,the labeledcells were always found in bed nucleus of stria terminalis,nucleus ventromedialis(hypothalami)and substantia nigra pars compacta.As the injections were given from lateral oblique approaches,labeled cells werenot found in the neo-cortex.There were no labeled cells demonstrated in the nuc-leus solitarius.In the above-mentioned areas nucleus ventromedialis(hypothalami),nucleusparabrachialis and locus coeruleus were often labeled bilaterally while others,ipsila-terally.

This article reports preliminarily the effects on the antibacterial activity & cytotoxicity of the derivatives of two diterpenoid components, Amethystoidin A & Rabdosia macrophylla C(i.e.Orido-nin ) which were isolated from the medicinal plants of Rabdosia ( Bl. ) Hassk. The experiment demonstrated that diacetate derivative of Amethystoidin A ( n ) could significantly enhance the antibacterial effect being 2 - 3 times more potent than that of Amethystoidin A. Hydrolytic derivative of Rabdosia macrophylla C (V) had a significant increase in the cytotoxicity on heptoma cell (QGY-7703 ) in vitro.

Household questionnaire survey was conducted in 200 residents of Tilan and Zhanhqiao neighborhoods, Xingang community, Shanghai to know their awareness of knowledge about pulmonary tuberculosis (TB) prevention and treatment. Results showed that 87.0% of the residents surveyed knew TB symptoms, but only 42. 5% knew cough and expectoration were pulmonary TB symptoms, 76. 5 % knew that TB could not be transmitted by use something that was used by TB patients, 85.5 % knew government policy of free and payment reduction for TB treatment, and 82. 0% knew there existed some hospitals for TB treatment designated by local health administrations. There was significant difference in the awareness between the two neighborhoods ( P ＜ 0. 01 ). Factors related to their awareness of TB prevention and treatment knowledge included family annual income, educational level, publicity by telecision and broadcasting.
