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.

Objective To observe the effects of Radix Hedysari on collagen area, hyaluronic acid (HA) and laminin (LN) of lung tissues in rat with pulmonary interstitial fibrosis; To investigate the mechanism and screen the best active ingredients in Radix Hedysari.Methods Totally 144 SPF Wistar rats were randomly divided into control group, model group, metacortandracin group, and Radix Hedysari polysaccharide, flavone and saponin groups were set as high-, medium-, and low-dose groups. Pulmonary interstitial fibrosis models were set up by dropping bleomycin into air tube of rats. All groups were taken corresponding medicine with appropriate dose daily on day 2 after models were established for 28 days. Collagen fibrils in lung tissue were observed by Masson dying and contents of HA and LN in lung tissue of rats in each group were detected by radioimmunoassay.Results Compared with the model group, pulmonary alveoli in Radix Hedysari flavone high-, medium-, and low-dose groups and Radix Hedysari polysaccharide low-dose group were relieved obviously; collagenous fiber area in Radix Hedysari flavone low-dose group, Radix Hedysari polysaccharide medium-dose group, and Radix Hedysari saponin low-dose group decreased obviously. Compared with the model group, the content of HA in Radix Hedysari polysaccharide high-dose group, Radix Hedysari flavone high-, medium-, and low-dose groups, and Radix Hedysari saponin high-dose group decreased obviously; the content of LN in Radix Hedysari polysaccharide high-dose group, Radix Hedysari flavone medium- and low-dose groups, and Radix Hedysari saponin medium- and low-dose groups decreased obviously. Conclusion Polysaccharide, flavone and saponin of Radix Hedysari have the abilities to alleviate inflammation of pulmonary alveoli, inhibit proliferation and deposition of collagen fibrils, and reduce the contents of HA and LA in lung tissue. Among these active ingredients, flavone has the best effect.

Objective To investigate the prognostic value of platelet to lymphocyte ratio (PLR) for early virological response in Entecavir (ETV)-treated chronic hepatitis B (CHB) patients with genotype C infection.Methods Ninety-one genotype C CHB patients with HBV DNA≥1×105 copies/mL were treated with ETV (0.5 mg/d) for 10-13 days.The correlation between PLR and viral load decline was evaluated by Pearson or Spearman's rank correlation coefficient.Stepwise linear regression analysis was used to establish the prediction model of virological response.Receiver operating characteristic (ROC) curves were used to evaluate the predictive value of PLR for early virological response in ETV-treated patients with genotype C hepatitis B virus (HBV) infection.Results After 10-13 days of ETV treatment, HBV DNA decreased ≥1×lg copies/mL from baseline in 89 cases of the 91 patients, while HBV DNA declined ≥2×lg copies/mL in 65 patients and 4 patients achieved HBV DNA<500 copies/mL.HBV DNA decline was positively correlated with baseline PLR levels (r=0.235 09, P<0.05).After adjustment for age, gender, Hepatitis B e Antigen (HBeAg), and treatment days, HBV DNA decline was still positively correlated with baseline PLR levels (r=0.220 26, P<0.05).Area under curve (AUC) of prediction model including age , baseline aspartate transaminase (AST) and HBV DNA was 0.759 (95% CI : 0.660-0.859, P<0.01).After adding PLR to the prediction model, the AUC was 0.780 (95% CI: 0.685-0.875, P<0.01).Conclusions PLR is predictive to early virological response in ETV-treated CHB patients with genotype C infection.Higher baseline PLR level indicates a better virological response.PLR monitoring should be recommended in CHB patients with antiviral treatment in clinical practice.

Objective To discuss the effects of Radix Hedysari flavonoids on microvessel density (MVD) of pulmonary interstitial fibrosis model rats, and provide evidence for its development. Methods SPF Wistar rats were divided into blank group, model group, prednisone group, and Radix Hedysari flavonoids high-, medium- and low-dosage group. Pulmonary interstitial fibrosis model was established by intratracheal instillation of bleomycin. From the second day after model established, each drug treatment group was administered with corresponding drugs intragastrically at different points in time for 14 and 28 days. MVD was detected by immunohistochemistry. Results Neomicrovessel was increased significantly in pulmonary tissue of model rats of 14 days treatment, but slightly decreased in 28 days. MVD in 14, 28 days model group was significantly more than blank group (P<0.01). MVD in 14, 28 days Radix Hedysari flavonoids high dosage group was significantly less than model group (P<0.01). MVD in Radix Hedysari flavonoids medium-dosage group was between high-and low-dosage group, and MVD in medium-dosage group was similar with that in model group. Conclusion Radix Hedysari flavonoids could inhibit the formation of neomicrovessel in a dose dependent manner.

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.
