OBJECTIVETo study the rule of syndrome differentiation in the patients with thoracic diseases at perioperation stage.

METHODSA standard was created referring to the related literature, and it was applied to differentiate the Chinese medicine syndrome in 150 patients before and three days after thoracic operation.

RESULTSBefore operation, Chinese medicine syndromes were as differentiated as phlegm type in 45.3%, blood stasis type in 17.3%, and qi-stagnancy type in 16.0%. The patients with asthenia syndrome markedly increased after operation, accounting for 34.0% (51 patients, including qi-, yin-, and blood-deficiency syndromes). The most frequently seen intermixed syndromes were qi-deficiency with phlegm-stasis syndrome and Pi ()-deficiency with phlegm-dampness syndrome. The intermixed syndromes revealed in 37.5% and 42.0% of the patients before and after operation, respectively.

CONCLUSIONSThe syndrome in the patients with thoracic disease before operation was mostly the excessive syndrome, mainly the phlegm syndrome type; at postoperation stage, Chinese medicine syndrome in patients become asthenia in essence with excessive superficiality, which is mostly revealed as Pi-deficiency with phlegm-dampness.

To investigate the Fe2+ effects on root tips in rice plant, experiments were carried out using border cells in vitro. The border cells were pre-planted in aeroponic culture and detached from root tips. Most border cells have a long elliptical shape. The number and the viability of border cells in situ reached the maxima of 1600 and 97.5%, respectively, at 20-25 mm root length. This mortality was more pronounced at the first 1-12 h exposure to 250 mg/L Fe2+ than at the last 12-36 h. After 36 h, the cell viability exposed to 250 mg/L Fe2+ decreased to nought, whereas it was 46.5% at 0 mg/L Fe2+. Increased Fe2+ dosage stimulated the death of detached border cells from rice cultivars. After 4 h Fe2+ treatment, the cell viabilities were > or =80% at 0 and 50 mg/L Fe2+ treatment and were <62% at 150, 250 and 350 mg/L Fe2+ treatment; The viability of border cells decreased by 10% when the Fe2+ concentration increased by 100 mg/L. After 24 h Fe2+ treatment, the viabilities of border cells at all the Fe2+ levels were <65%; The viability of border cells decreased by 20% when the Fe2+ concentration increased by 100 mg/L. The decreased viabilities of border cells indicated that Fe2+ dosage and treatment time would cause deadly effect on the border cells. The increased cell death could protect the root tips from toxic harm. Therefore, it may protect root from the damage caused by harmful iron toxicity.

OBJECTIVETo study the effect of Yiqi Bufei Recipe ([see text], YBR) on surgical tolerability, pulmonary compensatory function and post-operation rehabilitation in patients with pulmonary incompetence (PI) after pneumonectomy.

METHODSYBR intervention was applied to 60 patients with PI after pneumonectomy (as test group), the pulmonary and cardiac functions changes before and after operation, occurrence of postoperative complications, mortality, and the number of hospitalization days and intensive care unit (ICU) confinement period were observed. Meantime, for the negative and positive controls, the same parameters were observed comparatively in 60 patients with normal lung function, and in 60 patients with PI undergoing a similar operation but untreated with Chinese herbs.

RESULTSLung function in the test group showed insignificant change before and after operation (P >0.05), while significant decrease was seen in the two control groups (P<0.05). Furthermore, the incidences of post-operation complications and mortality as well as the number of hospitalization days and the ICU confinement period in the test group were significantly lower than those in the positive control group respectively (P <0.05).

CONCLUSIONYBR could relieve lung injury after pneumonectomy, improve surgical tolerability, reduce the length of postoperative hospitalization days and ICU confinement period, and lower the incidence of postoperative complications and mortality in patients with PI after pneumonectomy.

Objective Make use of image dentate nucleus and the veins around it on susceptibility weighted images (SWI), explore the correlation between the location of hilum of dentate nucleus and the venous variation of dentate nucleus. Methods Selecting 51 healthy adults (24 men, 27 women) at the age between 18 and 30 years old to get the original images on 3. 0T MR. Process the original images by minimum intensity projections (mIP) observed and analyzed the morphology of dentate nucleus and veins around it on original and processed images. Results The length of dentate nucleus was (16. 64±0. 20)mm, and the width was (8. 36±0. 14)mm. There was no significant difference between bilateral dentate nucleus. The median angle of the long axis of the dentate nucleus was 26. 80° (interquartile distance was 34. 58°). The venous network of dentate nucleus was formed in 2 groups of veins: the lateral group, drained by the vein of the horizontal fissure and nuclear vein; the medial group, drained by vermian vein and central vein of dentate nucleus. These two groups had been further typing as follows: the lateral anterior group drained by the nuclear vein, finally opening to superior petrosal sinus; the lateral median group had plenty of small veins of lateral dentate nucleus converge into the vein of the horizontal fissure; the lateral posterior group drained by a lot of very small veins converging to vermian veins or medullary veins; the medial anterior group that the central vein of dentate nucleus and the paravermian vein were jointed at hilum of dentate nucleus, opening into straight sinus; the medial posterior group usually converged into tributaries of vermian vein, or converged with paravermian vein into tributaries of vermian vein. Totally 75. 49% of hilums of dentate nucleus were located at upper inner quadrant, the other 24. 51% of them were located at lower inner quadrant. Conclusion Dentate nucleus and its veins are clearly visible on the susceptibility weighted images, and the location of the hilum of dentate nucleus may be related to the abouchement of paravermian vein.

Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.

Pituitary adenomas (PAs) are well known as a common intracranial benign tumor, and a portion of PAs are refractory to current therapeutic methods. ErbB receptors family signaling pathway regulates the expression of PAs activation associated gene. Inhibition of epidermal growth factor receptor (EGFR) can inhibit proliferation of PAs. Leucine-rich repeats and immunoglobulin-like domains protein 1 ( LRIG1), a negative mediated gene of ErbB receptors family, plays a role in many tumors. However, there are seldom researches about the functional role of LRIG1 in PAs. The aim of this study is to explore the potential effect of LRIG1 and its regulating mechanism in PAs. First, we investigated the role of LRIG1 in cell migration, invasion of PAs with transfected LRIG1 or control. Then, we explored its impact on cell proliferation and apoptosis of PAs in vivo. To study the regulating mechanism of LRIG1, we examined the expression of molecular factor of PI3K/AKT and Ras/Raf/ERK pathway using Western blotting in vitro and RT-PCR in vitro and in vivo. It was found that LRIG1 over-expression inhibited cell migration, invasion and proliferation, and promoted apoptosis of PAs in vivo and in vitro. Furthermore, LRIG1 suppressed the expression of signaling of PI3K/AKT and Ras/Raf/ERK pathways in PAs. LRIG1, as a negative mediated gene of tumor, can inhibit biological function of PAs via inhibiting PI3K/AKT and Ras/Raf/ERK pathways, and it might be a new target for gene therapy of PAs.
