With new acupuncture and moxibustion as the study object, based on the basic composition of acupuncture-moxibustion theory, from 3 aspects of meridian-acupoint theory, acupuncture-moxibustion method theory and acupuncture-moxibustion treatment theory, under the background of western medicine, ZHU Lian's different opinions on theory and method of acupuncture and moxibustion were discussed. It was believed by ZHU Lian that the distribution of 14-meridians was approximately identical to that of nerves, so with modern neuroanatomy knowledge to understand the meaning of acupoint; the acupuncture function could be explained from the angle of neurophysiology. Clinical diagnosis and treatment method could be established by modern classification methods of diseases. ZHU Lian's cognition that was different from traditional theory and method of acupuncture and moxibustion was combined with updated physiology and anatomy knowledge at that time, and was involved with Pavlov's advanced nerve theory, so she firstly put forward the opinion that acupuncture therapy can't work without the involvement of cerebral cortex.

Objective To observe the effects of Hedysari flavonoids on TGF-β1 and ultrastructure in lung tissue of rats with pulmonary fibrosis, and explore its mechanism. Methods Wistar rats were randomly divided into blank group, model group, prednisone group and Hedysari flavonoids high-, medium- and low-dose groups. Pulmonary fibrosis model was established by injection of bleomycin via trachea. After 24 h, rats were given drugs by gavage in all treatment groups once daily. The expression of TGF-β1 in lung tissue was detected by immunohistochemistry on d7, d14 and d28, and ultrastructure wasobserved by transmission electron microscope on d28. Results The positive expression of TGF-β1 was found in a few bronchiolar epithelial cell cytoplasm of blank group. Compared with the blank group, the positive expression of TGF-β1 on bronchial epithelial cell significantly increased (P<0.05) on d7, d14, and d28 in model group. Compared with the model group, the positive expression of TGF-β1 were significantly decreased (P<0.05, P<0.01) in Hedysari flavonoids high- and medium-dose groups and prednisone group on d7, d14 and d28. With electron microscopy, collagen fibers within the mediastinum in rat alveolar in model group were significantly increased, cell cytoplasm mitochondria was swollen in type Ⅱ epithelial cell.Mitochondrial crista was broken or disappeared, lamellar bodies significantly reduced. Collagen fibers reduced significantly in all treatment groups, which can improve and change ultrastructure on type Ⅱ epithelial cell. Conclusion Hedysari flavonoids can significantly reduce pathological damage and extracellular matrix deposition of rats with pulmonary fibrosis, which may have connection with inhibiting of TGF-β1 expression.

OBJECTIVESepsis, severe sepsis, and septic shock are frequently encountered and highly lethal conditions among children treated in ICU; however, no many reports on research on serum albumin levels of children under these conditions are available in literature and little is known about the relationship between serum albumin level and prognosis. In this prospective study, the author observed the levels of serum albumin of children with sepsis/severe sepsis/septic shock, and explored the relationship between serum albumin level and severity of illness or prognosis.

METHODFor sepsis/severe sepsis/septic shock patients admitted to the pediatric intensive care unit (PICU) during the year 2008, serum albumin concentration in peripheral blood was examined within 24 h after admission. According to the diagnostic criteria, hypoalbuminemia was defined as serum albumin level of < 35 g/L.

RESULTA total of 247 cases of sepsis/severe sepsis/septic shock children were enrolled. In the order of sepsis/severe sepsis/septic shock group, there were 143, 65 and 39 cases. Overall rate of hypoalbuminemia was 72.9% (180/247). The rate of hypoalbuminemia in children with sepsis, severe sepsis or septic shock was 59.4% (85/143), 86.2% (56/65) and 100% (39/39), respectively. The mortality of hypoalbuminemic patients in sepsis, severe sepsis and septic shock group showed significant difference (P < 0.001). The rates of hypoalbuminemia of the survived cases (69.5%) was significantly lower than that of the non-survived cases (94.1%). Pediatrics critical illness score (PCIS) and serum albumin concentration was positively correlated (P < 0.001), and the mortality was negatively correlated with serum albumin concentration (P < 0.05).

CONCLUSIONHypoalbuminemia is common among children with sepsis/severe sepsis/septic shock and serum albumin level is closely related to prognosis. Serum albumin level monitoring on the basis of PCIS scoring has important clinical prognostic significance in evaluating the prognosis of severe sepsis/septic shock patients.

Objective To use a simple bedside technique to verify the pathophysiological mechanism of pulmonary hypertension (PH) in different races. Method The Valsalva maneuver (VM) was performed in patients referred to a specialty PH clinic. The blood pressure response of patients to VM was in different fashions. The blood pressure (BP) was measured by using cuff and stethoscope. When the cuff was inflated to 15 mmHg above the systolic pressure, sound could be heard by auscultation during VM and when the cuff was deflated the sound disappeared over 3 heart beats which was considered as abnormal BP response, and less than 3 heart beats defined as normal BP response. The right heart catheterization in patients with PH as a part of the standard evaluation. Results This study included 84 patients with a mean age of (63 ± 16) years. Those with abnormal BP response to VM had higher pulmonary artery wedge pressure (PAWP) [(22.5±6.6) vs. (11.9±4.3) mmHg, P ＜0.0001] and lower pulmonary vascular resistance [(5.8 ± 4.0) vs. (8.1 ± 4.6 ) WU, P = 0.01]. Blood pressure response to VM did not correlate with mean pulmonary artery (PA) pressure [(46.2 ± 9.9) vs. (43.4 ±10.4) mmHg, P =0.20] or cardiac index (both 2.4 ± 0.6 L/min/m2). The abnormal BP response to VM had high sensitivity (89.4%), specificity (86.1%) and accuracy (86.9%) for determining PAWP＞ 15 mmHg.Conclusions BP response to Valsalva maneuver provides important information about left heart filling pressures in patients with PH.

Objective To study the effect of the extract of Chrysanthemum Indicum(CI)on the expression of tumor necro-sis factor-α (TNF-α) and neutrophil function in chronic bronchitis (CB)rats and to explore the therapeutic mechanism for chronic bronchitis. Methods The extract of CI was prepared. Wistar rats were randomly divided into blank control group, model group, Chuanxiling group, and low-, middle-and high-dose CI extract groups. Rat model of CB was established by intratracheal injection with low-dose lipopolysaccharide. After drug intervention, the expression of TNF-α in rat serum and bronchoalveolar lavage fluid was detected by ELISA method. Phagocytic function of the neu-trophil and respiratory burst of the rats were measured by flow cytometry (FCM). Results Compared with the blank con-trol group, the phagocytic function of the neutrophil, respiratory burst of the rats, and the expression of TNF-α in rat serum and bronchoalveolar lavage fluid of the model group were increased significantly. CI extract significantly decreased the abnormal rising of the above indexes. Conclusion Down-Regulation of TNF-α expression, and decrease of the neutrophil phagocytic function and rat respiratory burst may be one of the therapeutic mechanisms of Chrysanthemum In-dicum extract for the treatment of CB.
