Objective To explore the effect of Radix Isatidis( indigowoad root,RI) polysaccharide on NO and ET-1 in orthopotic liver autotransplantation of rats.Methods The rats used in the experiment were randomly divided into three groups:normal control group (NC), autotransplantation group (AT) and RI polysaccharide group (RIPS).At 1, 6, 12 and 24 hours after autotransplantation, the content of NO,ET-1, alanine aminotransferase ( ALT), and aspartate amin-otransferase ( AST) in serum was assayed.Morphological observation of hepatic tissues was also performed.Results The serum level of ET-1 in RIPS group was significantly lower than that of AT group (P<0.05), and NO content in serum of RIPS group was increased significantly compared with AT group ( P<0.05) at 1, 6, 12 and 24 hours after autotransplanta-tion.The serum level of ALT and AST in RIPS group was lower than that of AT group (P<0.05) at each measurement point.The morphology of hepatocytes changed abnormally under light microscopy.The blood stasis and swelling of hepatic tissues, denaturalization and necrosis of hepatocytes in RIPS group were milder than that in AT group.Conclusion RIPS has a protective effect on hepatic ischemia reperfusion injury after orthotopic liver autotransplantation, which may be related to increased NO levels and lower levels of ET-1.

OBJECTIVETo explore the clinical efficacy and effect mechanism on chronic urticaria treated with moving cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints.

METHODSOne hundred and four patients of chronic urticaria were randomized into a comprehensive therapy group and a medication group, 52 cases in each one. In the comprehensive therapy group, the moving cupping therapy along the governor vessel and bladder meridian of foot-taiyang was applied combined with autohemotherapy with acupaint injection for desensitization at acupoints. The self-venous blood was injected at bilateral Quchi (LI 11) and Zusanli (ST 36), 1 mL at each acupoint, once every 3 days. In the medication group, cetirizine tablets, 10 mg were prescribed for oral administration, once every day, and the compound dexamethasone acetate cream was used externally, once to twice a day. The clinical efficacy: was observed in 30 days of treatment in the two groups. The changes of serum interleukin 4 (IL-4) and immunoglobulin E (Ig E) before and after treatment were observed. The recurrence rate was compared between the two groups in 3 months after treatment.

RESULTSThe cured and markedly effective rate was 90.4% (47/52) in the comprehensive therapy group, which was higher obviously than 78.8% (41/52, P < 0.05) in the medication group. The levels of serum IL-4 and IgE were reduced in the patients of the two groups, indicating the significant difference in comparison before and after treatment (all P < 0.01) and the reducing degree in the comprehensive therapy group was much more significant than that in the medicine group (both P < 0.01). The recurrence rate was 19. 1% (9/47) in the comprehensive therapy group in the 3-month follow-up after treatment, and apparently lower than 51.2% (21/41, P < 0.01).

CONCLUSIONThe moving cupping therapy combined with autohemotherapy with acupaint injection for desensitization at acupoints achieves the better efficacy on chronic urticaria compared with the routine western medicine treatment and the recurrence rate is low. The effect mechanism is possibly related to the down-regulation of serum IL-4 and IgE in the patients.

Objective To investigate characteristics of endometriotic lesions clone with various pathological subtypes by analyzing the polymorphism of X chromosome linked human androgen receptor allele (HUMARA). Methods Eight frozen tissues of endometriotic leisons were collected from 6 patients who received laparotomy or laparoscopy surgery in Peking Union Medical College Hospital from Nov. 2008 to Jun. 2009. Fifty specimens of epithelial cells from single endometrial glands were isolated and collected from endometriotic lesions by using laser capture microdissection. HUMARA was applied as the gene marker of clonal analysis. Nested palymerase chain reaction, double-enzyme digestion reaction with two methylationsensitive restriction endonuclease (Hha Ⅰ and Hpa Ⅱ), and the automated gene sequencing technique were utilized in this study to evaluate the characteristics of endometriotic lesions clone. Results Of 50 specimens of isolated glands, 34 were informative for clonal analysis, and all of which showed monoclonality. Of 3 ovarian endometriotic tissues, one tissue of HUMARA showed unuseful information, the other 2 ovarian endometriotic tissues respectively had 4 and 7 informative specimens of gland epithelial cells, and all of the glands from each tissue showed uniform clonal pattern. Two peritoneal endometriotic tissues had 1 and 5 informative specimens from individual glands, respectively; and the clonal patterns in 5 glands from the single lesion were divergent. Two abdominal wall endometriotic tissues had 7 and 6 informative specimens,respectively; and variable clonal patterns were seen in different glands from each lesion. One deep infiltrating endometriotic lesion had 4 informative specimens of isolated glands, and all of them showed unique clonal pattern. The disparate clonal patterns were found in endometriotic lesions with variable pathological subtypes, even arising from the same patient. Conclusions The epithelial cells from individual endometriotic gland showed monoclonality , and different glands from the same endometriotic lesion might show divergent patterns.

Objective To observe pulmonary fibrosis in severe acute respiratory syndrome (SARS) and to discuss the mechanisms of pulmonary fibrosis in SARS. Methods Hematoxylin and Eosin staining (H&E), histology staining and immuno-histochemical staining (SP methods) were used to investigate the lungs from 4 autopsy cases. Antibodies against collagen type Ⅲ, ?-smooth muscle actin(?-SMA), Fas, FasL and transforming growth factor ?1(TGF-?1) were used for immunohistochemical studies. Results All these four lung tissues showed different degree of pulmonary fibrosis, including the organization of exudative fibrin, glomerulus-like fibrosis in alveolar spaces, the thickening of the alveolar septum, proliferation of fibroblasts, the hyperplasia of collagen fibers and the consolidation of lungs. Sirius red staining and collagen type Ⅲ staining showed the type Ⅲ and the type Ⅰ collagen fibers were the main components of the hyperplastic collagen fibers. ?-SMA were expressed in fibroblasts, immunoreactivity to Fas, FasL, TGF-?1 were all positive and located in plasma of pneumocytes, macrophages and lymphocytes. Conclusions The pulmonary fibrosis can be observed early in SARS patients and the pathogenesis may be involved in the co-effect of many effective cells, inflammatory mediators and cytokines.
