Objective To explore the TCM syndrome of IgAN, and formulate standard scheme on differentiation of symptoms and sings. Methods Adopted epidemiological investigation of TCM syndrome, and analyzed the relativity of clinic and pathology with the TCM syndrome. Results Two schemes of TCM showed that the qiyinliangxu syndrome was primary pattern of IgAN. The TCM syndrome showed changes of single syndrome (qiyinliangxu) → bideminy syndrome (qiyinliangxu accompanied shenluoyubi or fengshineirao)→ trigeminy syndrome (qiyinliangxu accompanied shenluoyubi and fengshineirao) with the aggravation of IgAN.Conclusions The New Scheme was more predominant in differentiation of symptoms and sings than The Old Scheme, and The New Scheme was more easy to operat and master. It was worthy to spread and utilize The New Scheme in clinic.

The present study was performed to investigate the significance and potential role of signal transducers and activators of transcription 3 (STAT3) activation in postburn Staphylococcus aureus sepsis. Seventy one male Wistar rats were randomly divided into five groups: normal controls, scald control group, postburn sepsis group, AG490 (JAK2 inhibitor) treatment group, and rapamycin (RPM, STAT3 inhibitor) treatment group. Tissue samples from the liver and lung were collected to determine activation of STAT3, and interferon ? (IFN ?) mRNA as well as protein expression. The results showed that activation of STAT3 was quickly up regulated at 0 5～1 hour following thermal injury combined with Staphylococcus aureus challenge in the liver and lung, and it gradually weakened after 2 hours. Treatment with AG490 or RPM could inhibit activation of STAT3 at 0 5 hour in the liver and lung. Meanwhile, IFN ? mRNA expression markedly declined at 2 hours after treatment with AG490 or RPM in the liver and RPM in the lung ( P

Objective To investigate the trends of incidence for cervical cancer in the years of 1973-2000, in Qidong, a city in south China, with a population of 1. 16 M. Methods Crude incidence rate of cervical cancer was calculated by using incident case data from Qidong Cancer Registry, which was founded in 1972, and age-standardized rates were computed according to China age structure of 1964 (CASK), and world age structure of 1960 (WASR). The epidemiological features and secular change trends of the cancer were described. Results Six hundred and thirty-one new cases of cervical cancer were-reported in Qidong during the years of 1973 to 2000, ranking the eighth and accounting for 3. 25% among all sites of cancers in women. The crude annual incidence rate during the period was 3. 96 per 100 000 on average, China age-standardized rate ( CASK) was 2. 67 per 100 000, and world age-standardized rate (WASR) , 3. 66 per 100 000. The incidence of cervical cancer was 2. 97 per 100 000 for the last 14 years, and 5. 01 per 100 000 for the first 14 years, showing a decreasing trend ( P

Methods: The HBV gene vaccine was injected into tibialis anterior muscles of C57BL/6 mice. ELISA was used to detected the anti-HBs antibody in mice sera at various time points after gene transfer. Results: Anti-HBs in sera of mice was tested positive 1 week after plasmid injected, the level of antibody peaked 4 weeks later, and kept high titer for at least 2 months. Conclusion: The good response of humoral immunity can be induced by injection of pCMVS 2-S in C57BL/6 mice.

Objective: To evaluate the effects and partly mechanism of Qileng decoction(QLD,芪棱汤) resisting focal cerebral ischemia/reperfusion(I/R) injury in rats by apoptosis and signal transduction pathway.Methods: The rats were randomly divided into three groups including sham operation group,normal saline(NS) control group and QLD group.The model of focal cerebral I/R injury was induced by using modified thread embolizing in rats.Rats were evaluated by neurologic function score at 2 hours after ischemia and 2,4,6,12,24 and 48 hours after cerebral reperfusion,and the pathological changes of nerve cells and mitochondria ultrastructure at pallium and hippocampus CA1 region were observed at 24 hours after reperfusion.Immunohistochemical method was performed to examine the expression of cytochrome C(cyt C) and caspase-9 at different time points after reperfusion.Apoptosis of nerve cells in ischemic penumbra(IP) was also characterized by terminal deoxynucleotidyl-transferase mediated dUTP-biotin nick end labeling(TUNEL) method.Results: Compared with NS control group,neurologic function scores at different reperfusion time points were improved and the pathological changes were ameliorated at 24 hours after cerebral I/R in QLD group.Mitochondria hydropsia was alleviated,mitochondrial cristae fragmentation and granulum basale shedding were diminished,and mitochondrial basical morphology was retained.Meanwhile,apoptosis index(AI) was decreased and the expressions of cyt C and caspase-9 were reduced in IP in QLD group.Conclusion: QLD intervenes in mitochondria mediated and caspase-9 dependent apoptopic pathway.QLD lowers AI and plays a role of protecting nerve by maintaining mitochondrial basical form,stabilizing mitochondrial membrane and inhibiting the release of cyt C and activation of caspase-9.The above actions are possibly some parts of mechanisms of QLD resisting focal cerebral I/R injury.

Objective To explore the high-risk factors,clinical characteristics,therapy and prognosis of invasive fungal infection (IFI)in patients underwent allogeneic haemopoietic stem cell transplantation (AlloHSCT). Methods One hundred patients underwent Allo-HSCT at our department from March 2002 to July 2010 were analyzed retrospectively,among whom 26 patients had invasive fungal infection(IFI). Seven patients had pulmonary IFI before allo-HSCT, 14 patients had pulmonary IFI after allo-HSCT,3 patients had respiratory tract system IFI, and 2 patients had intestinal IFI. We observed the occurrence of Graft-versus-host disease (GVHD) ,cytomegalovirus( CMV )infection, Lymphocyte subsets and chronic basic diseases in patients with IFI. The twenty six cases were divided into two groups: experience therapy group with 12 cases and preemption therapy group with 14 cases. Results Among 26 patients with IFI,20 cases suffered from GVHD,6 cases had CMV infection,19 cases had low cellular immune function simultaneously. 1 case had diabetes,3 patients had pulmonary tuberculosis and 1 case had bronchiectasis as complications. In experience therapy groupe: 8 cases (67%)recovered completely but 1 case(8% )suffered from progressive infection. In preemption therapy groupe:3 cases ( 21% ) recovered completely but 5 cases ( 36% ) suffered from progressive infection. Conclusion Clinician should pay close attention to the patients with high-risk factors of IFI after allo-HSCT.

Objective To evaluate the therapeutic effects of allogeneic hematopoietic stem cell transplantat (allo-HSCT) for severe aplastic anemia (SAA). Methods Four patients of SAA underwent allo-HSCT at the bonemarrow transplant unit in our hospital from March 2003 to May 2009. Stem cell source was an HLA (human leukocyte antigen) matched related donor (MRD) in 3, HLA 1 (B) mismatched related donor in 1 patient A retrospective analysis was performed on interval from diagnosis to transplant,HSCT manners,conditioning regimens, hematopoiesis reconstitution, effectiveness and complication. Results The interval from diagnosis to transplant was 70 (19 - 180) days. Three patients (MRD) underwent BM + PBSCT, one was undergone BM + PBSC + CBSCT. Conditioning regimens of all patients were CY/ATG. Hematopoiesis reconstitution was achieved in 4 patients (100%). The median time of neutrophils which reached 0. 5 x 109/L and platelets reached 20 × 109/L were 14. 5 (9-28) and 16(9 -28) days. Two cases developed grade Ⅰ acute graft-versus-host diseaes (aGVHD), chronic local GVHD occurred in one patient. Four patients are alive with a median time of 40. 6(2 -63) months at the end of the following-up. Conclusions Allo-HSCT are an efficient and safe therapy for the patient with SAA,not only for patients with HLA matched related donor,but also for those only HLA mismatched related donor available.
