Objective: To study the effective substance foundation of Ephedrae Herba and explore its mechanism, in order to further enrich the theory of drug resistance of Ephedrae Herba.Method: In this experiment, a compound model was used to establish rat model of Harmful Fluid Retention in upper Jiao. The Rats were randomly divided into model group, captopril group (4.38 mg·kg-1), Ephedrae Herba decoction group(468 mg·kg-1), polysaccharide group (265.36 mg·kg-1), volatile oil group (2.34 mg·kg-1), alkaloid group(40.71 mg·kg-1) and phenolic acid group (210.60 mg·kg-1), and normal group (10 mL·kg-1). The normal group and the model group were given the same volume of normal saline for four weeks. The 24 h urine volume of rats was collected by metabolic cage method. The changes of heart and lung tissue morphology were observed under light microscope. The heart index, lung index, left ventricular ejection fraction(LVEF), left ventricular short axis shortening rate(LVFS) and pulmonary permeability index, number(LPI), lung dry-wet ratio(W/D), creatine kinase isoenzyme(CK-MB), angiotensin Ⅱ(Ang Ⅱ), aldosterone(ALD), cardiac aquaporin 1(AQP1), lung AQP1, aquaporin-3(AQP3) and kidney AQP1, aquaporin-2(AQP2), interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) change were detected.Result: Compared with the normal group, heart and lungs of the model group were significantly damaged. The amount of 24 h urine, LVEF, LVFS of model rats were significantly reduced(Pα were significantly increased(PPα were significantly increased (PPα were significantly reduced (PPConclusion: Alkaloid components "Wen" and "Xin" are the effective substance basis of its action. The mechanism may be related to the inhibition of renin angiotensin aldosterone system (RAAS) and the anti-inflammatory effect.

Subdivision of mobile learning behaviors of undergraduates majoring in traditional Chinese medicine in different learning circumstances / 中华医学图书情报杂志

Mobile learning behaviors are the greatly concerned hotspot in educational field.However, the specific mobile learning behaviors of university undergraduates are not subdivided in the current researches.The mobile learning behavior data of university undergraduates in different learning circumstances were recorded by literature survey, interview and questionnaire investigation, the characteristics of mobile learning behaviors were subdivided and analyzed in order to help them work out their strategy for mobile learning in different learning circumstances, which showed that the frequency of intelligent mobile learning was higher than that of traditional mobile learning in specific academic activities (academic exchange, self learning, academic sharing, transmission and search), and that the new generation of digital young people showed their preference to mobile learning due to its advantage of convenience while the disadvantage of its function and operation limited its persistent use.It is thus the hope of university undergraduates, especially medical undergraduates, to develop more devices and tools that are convenient for their mobile learning by making use of the advantages of intelligent mobile terminal and traditional terminals.

Cone-beam computed tomographic evaluation of the temporomandibular joint and dental characteristics of patients with Class II subdivision malocclusion and asymmetry / 대한치과교정학회지

OBJECTIVE: Treating Class II subdivision malocclusion with asymmetry has been a challenge for orthodontists because of the complicated characteristics of asymmetry. This study aimed to explore the characteristics of dental and skeletal asymmetry in Class II subdivision malocclusion, and to assess the relationship between the condyle-glenoid fossa and first molar. METHODS: Cone-beam computed tomographic images of 32 patients with Class II subdivision malocclusion were three-dimensionally reconstructed using the Mimics software. Forty-five anatomic landmarks on the reconstructed structures were selected and 27 linear and angular measurements were performed. Paired-samples t-tests were used to compare the average differences between the Class I and Class II sides; Pearson correlation coefficient (r) was used for analyzing the linear association. RESULTS: The faciolingual crown angulation of the mandibular first molar (p < 0.05), sagittal position of the maxillary and mandibular first molars (p < 0.01), condylar head height (p < 0.01), condylar process height (p < 0.05), and angle of the posterior wall of the articular tubercle and coronal position of the glenoid fossa (p < 0.01) were significantly different between the two sides. The morphology and position of the condyle-glenoid fossa significantly correlated with the three-dimensional changes in the first molar. CONCLUSIONS: Asymmetry in the sagittal position of the maxillary and mandibular first molars between the two sides and significant lingual inclination of the mandibular first molar on the Class II side were the dental characteristics of Class II subdivision malocclusion. Condylar morphology and glenoid fossa position asymmetries were the major components of skeletal asymmetry and were well correlated with the three-dimensional position of the first molar.

Caracterización morfológica del músculo bíceps femoral del perro / Morphological characterization of biceps femoris muscle in the dog

A partir de estudios previos realizados sobre la anatomía del musculo bíceps femoral en el perro y con el objetivo de avanzar en la caracterización inmunohistoquímica y nerviosa de este musculo, estudiamos la existencia de subvolúmenes musculares. Utilizamos la disección roma en piezas musculares aisladas fijadas y tratadas con ácido nítrico al 25%. Las divisiones de las ramas del nervio isquiático involucradas fueron utilizadas como guía en la disección. Se determinaron tres subvolúmenes, uno involucrando a la cabeza caudal y dos en el vientre correspondiente a la cabeza craneal que fueron denominados caudal, proximal y distal respectivamente. Realizamos mediciones del largo de las fibras musculares, dirección, dirección y densidad macroscópica de las mismas para caracterizar los compartimientos. Estos subvolúmenes deberán tenerse en cuanta al realizar estudios electromiográficos del musculo bíceps femoral y al evaluar las alteraciones en la locomoción producto de las alteraciones nerviosas y musculares en el nervio pelviano del canino.

From previous studies on the anatomy of the femoral biceps muscle in the dog and with the aim of advancing in immunohistochemical and nervous characterization of this muscle, we studied the existence of subvolumes in muscle structure. We used blunt dissection in isolated muscle pieces fixed and treated with 25% nitric acid. The divisions of the sciatic nerve branches involved were used to guide the dissection. Three subvolumes were identified; one, involving the caudal head, and two in the cranial head belly; they were called caudal, proximal and distal respectively. We measured muscle fiber length, orientation, and macroscopic density to characterize these compartments. These subvolumes must be considered when muscle electromyography research is carried out, and for locomotion changes evaluation due to lesions in nerve and muscle structure of the canine pelvic limb.

Estudo comparativo das alterações cefalométricas do tratamento da má oclusão de Classe II, subdivisão, realizado com extrações de um ou de três pré-molares / Cephalometric evaluation of dentoskeletal and tegumental changes of Class II, subdivision treatment with asymmetric extraction protocols

O objetivo deste trabalho foi comparar os resultados das alterações cefalométricas dentárias, esqueléticas e tegumentares, de casos com má oclusão de Classe II, subdivisão, tratados sob dois protocolos distintos de extrações assimétricas. A amostra foi constituída por 126 teleradiografias em norma lateral de 63 pacientes, os quais foram divididos em dois grupos. O Grupo 1 foi formado por 32 pacientes com má oclusão de Classe II, subdivisão, com idade média inicial de 13,98 e final de 16,90, tratados com extração assimétrica de um pré-molar superior do lado da relação de Classe II.O Grupo 2foi composto por 31 pacientes com má oclusão de Classe II, subdivisão, com idade média inicial de 13,58 e final de 16,83, tratados com extrações assimétricas de três pré-molares, sendo dois superiores e um inferior do lado da relação de Classe I.A comparação intergrupos das alterações do tratamento foi realizada através do teste t. Os resultados demonstraram a existência de diferenças estatisticamente significantes entre as alterações proporcionadas pelos dois tratamentos em relação: ao componente dentoalveolar inferior, onde a terapêutica realizada com uma extração propiciou a vestibularização e protrusão dos incisivos inferiores, ao contrário da terapêutica com três extrações que propiciou uma lingualização e retrusão dos mesmos.Os dois grupos apresentaram uma melhora na relação maxilomandibular. O índice de assimetria dos molares superiores aumentou no grupo com uma extração, enquanto que o grupo com três extrações apresentou um aumento no índice de assimetria dos molares inferiores. Os dois grupos apresentaram semelhanças quanto às alterações do perfil tegumentar.

The purpose of this study was to cephalometrically compare the dentoskeletal and soft-tissue changes consequent to orthodontic treatment in patients with Class II subdivision malocclusion treated with asymmetric extraction protocols. The sample consisted of 126 lateral cephalograms of 63 patients, divided into two groups. Group 1 consisted of 32 patients with Class II, subdivision malocclusion, and had initial and final mean ages of 13.98 and 16.90, treated with asymmetric extraction of one maxillary premolar on the Class II side. Group 2 consisted of 31 patients with Class II, subdivision malocclusion, and had initial and final mean ages of 13.58 and 16.83, treated with asymmetric extractions of two maxillary premolars and one mandibular premolar on the Class I side. T tests were used to compare the groups at pretreatment and the treatment changes between groups. The results demonstrated that group 1 had mandibular incisor protrusion, while group 2 had lower incisor retraction. The maxillary molar asymmetry index increased in group 1, on the contrary of group 2 that had mandibular molar asymmetry index increase. Both groups had similar soft-tissue changes.

Does T3 Subdivision Correlate with Nodal or Distant Metastasis in Colorectal Cancer?

PURPOSE: We analyzed the clinical data of T3 colorectal cancer patients to assess whether T3 subdivision correlates with node (N) or metastasis (M) staging and stage-independent factors. METHODS: Five hundred fifty-five patients who underwent surgery for primary colorectal cancer from January 2003 to December 2009 were analyzed for T3 subdivision. T3 subdivision was determined by the depth of invasion beyond the outer border of the proper muscle (T3a, 5 to 15 mm; T3d, >15 mm). We investigated the correlation between T3 subdivision and N, M staging and stage-independent prognostic factors including angiolymphatic invasion (ALI), venous invasion (VI) and perineural invasion (PNI). RESULTS: The tumors of the 555 patients were subclassified as T3a in 86 patients (15.5%), T3b in 209 patients (37.7%), T3c in 210 patients (37.8%) and T3d in 50 patients (9.0%). The nodal metastasis rates were 39.5% for T3a, 56.5% for T3b, 75.7% for T3c and 74.0% for T3d. The distant metastasis rates were 7.0% for T3a 9.1% for T3b, 27.1% for T3c and 40.0% for T3d. Both N and M staging correlated with T3 subdivision (Spearman's rho = 0.288, 0.276, respectively; P < 0.001). Other stage-independent prognostic factors correlated well with T3 subdivision (Spearman's rho = 0.250, P < 0.001 for ALI; rho = 0.146, P < 0.001 for VI; rho = 0.271, P < 0.001 for PNI). CONCLUSION: Subdivision of T3 colorectal cancer correlates with nodal and metastasis staging. Moreover, it correlates with other prognostic factors for colorectal cancer.

Statistical analysis of heavy metals from water samples of Tezpur sub-division in Sonitpur District, Assam, India.

Analysis of heavy metals of water samples from Tube wells, Ring wells, Ponds and Rivers were carried out during year 2008 and 2009. Samples were analyzed using standard methods. To assess the quality of drinking water, each parameter was compared with the standard desirable limit of that parameter in drinking water as prescribed by different agencies. The results from the analysis of water show that the highest PH was recorded in premonsoon season, but lowest value recorded in monsoon season. All the sources have PH within the maximum limit. The copper and zinc concentrations in all sources were below the permissible limit but in case of nickel all the sources have its value exceed the limit. Chromium was detected during post monsoon and winter seasons. Two sources have chromium values exceed the permissible limit. In the present study, maximum amount of arsenic in all seasons is recoded from Ring wells only. The statistical parameters such as Mean, Variance, Standard deviation (SD) and Coefficient of variation (CV) were calculated. Correlation Coefficient Matrix among the parameters was calculated and correlations between various parameters were worked out. Significant positive and negative correlations among the parameters were determined.

An orthodontic-surgical approach to Class II subdivision malocclusion treatment

Despite the different orthodontic approaches to Class II subdivision malocclusions one has also to consider the skeletal components before undertaking any treatment protocol. Significant involvement of the skeletal structures may require a combined surgical orthodontic treatment, which has remained stable for more than four years, as illustrated in this case report.

Clinical Significance of Subdividing Gastric Cancer according to the Degree of Invasion of the Muscularis Propria

PURPOSE: Some gastric cancer patients in whom the cancer has infiltrated up to the muscularis propria (mp) have a good postoperative course similar to that of early gastric cancer (EGC) patients (this does not match the general classification of gastric cancer). Therefore, we performed a retrospective analysis of 125 patients with mp gastric cancer based on the degree of mp invasion. MATERIALS AND METHODS: The clinicopathologic features of 125 cases of mp gastric cancer were subdivided according to depth of invasion, and were retrospectively reviewed and compared with the surgical features of 222 patients with gastric cancer invading the submucosa (sm). For each tumor, using the section that showed the greatest extent of invasion, we evaluated the degree of tumor invasion into the mp layer at a magnification of x100. The patients were classified into 2 groups: mp1, the tumor was limited to the first of the 3 mp layers, and mp2, the tumor had expanded beyond the first layer. RESULTS: Patients with mp1 (n=50) had a significantly lower incidence of lymph node metastasis, and a smaller tumor size than patients with mp2 (n=75)(P=0.01 and P=0.029, respectively). The 5-year survival rate of mp1 patients was significantly better than that of mp2 patients (95.3% vs. 77.6%, P=0.0282), but was similar to that (91.2%) of the 222 sm patients. The 5-year survival rate of mp patients without lymph node metastasis (n=55) was significantly better than that of those with lymph node metastasis (n=70)(93.3% vs. 78.2%, P=0.0192). Patients with mp1 had a significantly higher incidence of lymph node metastasis (42.5% vs 23%, P=0.006) than patients with sm. CONCLUSION: There were clear differences in clinical features between the mp1 and the mp2 patients. Subdivision of mp gastric cancer according to the depth of invasion may enable a more precise prognosis and a more pertinent treatment plan for mp patients. In particular, as the clinicopathological findings and surgical outcomes for mp1 patients were akin to those of the sm patients, mp1 patients may require treatment analogous to that administered to patients with sm gastric cancer.

Analysis of the marketing of hospital service / 中华医院管理杂志

Hospitals, obliged to resort to marketing as a result of changing external environment, ought to take the concept of patient-centered marketing as the core of their marketing activities. They can better meet the needs of patients by making their marketing plans more effective through market subdivision and target market selection. The features of medical service determine the role of credit in the evaluation of medical service. Differentiation, two major methods of which are service quality and brand creation, is a means of avoiding price war, over-competition and vicious competition while positioning refers to patients' understanding and the goal of a hospital's differentiation.

THE SUBMICROSCOPIC STRUCTURE OF THE VENTROLATERAL SUBDIVISION OF THE MIDBRAIN PERIAQUEDUCTAL GRAY OF THE RAT / 解剖学报

The transmission electron microscopic technique was used in the present study to observe the normal ultrastructure of the ventrolateral subdivision (VLS) of the rat midbrain periaqueductal gray (PAG). Most of the neurons in the VLS of PAG had medium-sized fusiform neuronal cell body, ellipsoid nucleus and irregular nuclear membrane with deep invaginations or infoldings. The nucleolus was electron dense, large and spheroidal. There were many kinds of organelles in the cytoplasm and the Golgi apparatus in some cells were circular or semicircular. The percentage of axo-somatic synapse in total synapses in VLS was 6% and most of them was of symmetric type (82%). Axo-dendritic synapses counted 94%, of these 66% were symmetric type, 34% were asymmetric. Some special types of axo-dendritic synapse were observed. e. g., axo-spine synapse, parallel synapse, and central dendritic synaptic glomerulus. The synaptic vesicles in the presynaptic bags of the synapses mentioned above were mainly clear spherical in type, and most of the clear spherical vesicle-filled bags contained a few flattened vesicles and granular vesicles. Only a few bags were mainly filled with flattened vesicles.
