OBJECTIVETo investigate the effect of Suanzao nacute hepatic failure in mice.
METHODAcute liver failure was induced in male Kunming strain mice by enterocoelia injecting the animals with D-Gal-N and LPS. The mice in treatment groups were given corresponding drug 2 h before administration of D-Ga1-N and LPS, and the mice in control group were given the same dose of distilled water. The 24 h survival rate, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) levels were compared. Serum the levels of TNF-alpha and IL-1 and the levels of SOD, MDA, GR, GSH, NO and NOS in the liver were determined.
RESULTTreatment with suanzaoren decoction could increase the survival rate and improve the liver histological feather. Suanzaoren decoction inhibited the serum the levels of ALT, AST, TNF-alpha and IL-1, and reduced the levels of MDA, NO and NOS and increased the levels of GR and SOD in the liver.
CONCLUSIONTreatment with Suanzaoren decoction can suppress the D-Gal-N/LPS-induced acute hepatic failure. It may be the mechanism that Suanzaoren decocotion regulate the production of inflammatory cytokines and free radicals.

OBJECTIVETo investigate the curative effect and safety of auxiliary treatment with Suanzaoren Decoction (SZRD) on patients with chronic severe hepatitis (CSH).
METHODSSixty patients, with the diagnosis in accordance with the diagnostic criterion of CSH, were assigned to the treated group and the control group, 30 in each group. Patients in the control group were treated with comprehensive therapy including symptomatic supportive treatment, anti-infective therapy and artificial liver plasmapheresis etc., while those in the treated group were orally taken SZRD additionally. Patients' condition of sleeping and changes of total bilirubin (TBIL), prothrombin activity (PTA), tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1) were observed before and after treatment, and the adverse reactions were observed as well.
RESULTSThe sleeping status were significantly improved in the treated group after treatment, and the serum levels of TBIL, TNF-alpha and IL-1 were significantly decreased. The improvement rate was 66.7% (20/30) and significantly higher than that (40.0%, 12/30) in the control group.
CONCLUSIONSZRD can significantly improve the sleeping status of CSH patients, alleviate the hepato-cellular injury by inflammatory cytokines and without obvious adverse reaction.

OBJECTIVETo compare the application of HE and enzyme histochemical staining in assessing the viability of hepatocellular carcinoma (HCC) cells coagulated by microwave ablation at different temperatures.
METHODSTwo groups of mice (n=6) with transplanted homogenic HCC were treated by microwave ablation at 60 degrees C and 50 degrees C for 3 min, respectively. Before and after microwave ablation, paraffin sections and frozen sections of the tumors were prepared for routine HE staining and enzyme histochemical staining with nicotinamide adenine dinucleotide diaphorase (NADH-diaphorase), respectively, and observed under microscope.
RESULTSShortly after microwave ablation, the morphology and arrangements of the nucleus of the ablated tumor cells in the two groups showed no obvious alteration in HE stained sections, but in sections with enzyme histochemical staining, the activity of NADH-diaphorase in ablated tumor tissue at 60 degrees C disappeared, suggesting the death of HCC cells; sporadic activity of the enzyme was detected in the coagulated tumor at 50 degrees C, indicating tumor cells surviving the ablation. The ablation effect was markedly different between the two groups (P<0.01).
CONCLUSIONHE staining is not suitable for evaluation of HCC destruction immediately after microwave ablation, and detection of NADH-diaphorase activity with the enzyme histochemical method better suits this purpose.

Objective:This study was designed to investigate the outcome of double autologous hematopoietic stem cell transplantation(Double AHSCT) in hematological malignancies. Methods: The clinical data of 12 patients who underwent Double AHSCT between January 1995 and January 1999 were analyzed retrospectively and the outcome were compared with that of 17 patients who received single autologous hematopoietic stem cell transplantation (Single AHSCT) in the same period. Results: The duration of continuous remission in 12 patients undergoing Double AHSCT ranged from 6 to 68 months(mean 27 months). Among them, eight patients (66.7% ) were still alive without relapse up to now. While one patient had relapsed 6 months after second grafting. Three patients died from diseases related to graft. The patients who received Single AHSCT had a continuous remission of 1- 36 months after graft (mean 12 months). Six of the 17 patients were still alive in good condition. Eight patients relapsed and 3 patients died from diseases related to graft. Conclusion: Good outcome were showed in Double AHSCT for the treatment of hematological malignancies. The 18 month survival rate in Double AHSCT tended to be better than that in Single AHSCT.

ObjectiveTo further study the pathogenic role of different types of Chlamydia trachomatis (CT) proteins in tubal factor infertility, evaluate the clinical detection value of Chlamydia trachomatis protein antibody in predicting tubal factor infertility. MethodsA total of 58 cases of tubal factor infertility (TFI), 41 cases of fertile controls (FC) and 18 cases of infertile controls (IFC) were included. For serum detection, first, CT-IgG ELISA kit was used to detect the expression of CT-IgG in serum of three groups of people; then, 6 kinds of Chlamydia trachomatis proteins were expressed and purified in the early stage to establish the antibody test for these proteins, and ELISA detection method was used to detect the expression of their antibodies in the serum of TFI group, FC group and IFC group, respectively; and finally, the antibody OD value of the 6 kinds of Chlamydia trachomatis proteins in the three groups of subjects were statistically described, and CT-IgG was used as the reference standard to draw the receiver operating characteristic curve (ROC curve) of each CT antibody. The Youden Index determines the cutoff value for each antibody. Taking TFI as the reference class, two disordered multiple classification logistic regression models were established with the FC and IFC groups, respectively; and the reference class was used to explore the value of various antibodies and age in predicting TFI, FC and IFC of Chlamydia trachomatis. The back-off method was used to screen the variables. ResultsThe OD value of CT376 antibody in the TFI group was higher than that in the FC group (0.86 vs. 0.60, P=0.026). The CT376 antibody OD value in the TFI group was higher than that in the IFC group (0.86 vs. 0.64, P=0.026). The CT443 antibody OD value in the IFC group was higher than that in the TFI group (0.59 vs. 0.34, P=0.036) and higher than that in the FC group (0.59 vs. 0.30, P=0.02). The multiple classification logistic regression analysis established between TFI and FC showed that CT-IgG [P<0.001, OR=0.084, 95%CI (0.025, 0.284)], CT376 antibody [P=0.068, OR=0.359, 95%CI (0.120, 1.078)]. CT-IgG is an independent risk factor for tubal infertility, and CT376 antibody cannot be an independent risk factor for tubal infertility. The multiple classification logistic regression analysis established between TFI and IFC showed that among infertile patients, CT-IgG [P<0.05, OR=0.194, 95%CI (0.046, 0.817)], CT376 antibody [P<0.05, OR=0.176, 95%CI (0.038, 0.818)] and CT381 antibody [P<0.05, OR=0.112, 95%CI ( 0.016, 0.796)] were independent risk factors for tubal infertility. ConclusionThe expression of CT376 antibody in tubal infertility patients is higher than that in fertile and infertile controls, suggesting that CT-induced tubal factor infertility may be related to CT376. CT-IgG, and CT376 antibodies are meaningful in predicting CT-induced tubal factor infertility.

OBJECTIVETo retrospectively analyze the curative effects and prognostic factors of HLA-matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic myelogenous leukemia patients (CML).
METHODSOf the 35 CML patients, 26 were males and 9 were females, with a median age of 32 (12 - 50) years. 30 patients were in chronic phase of CML, 5 patients were in accelerated phase. Allo-HSCT from HLA identical siblings was performed for 35 patients, of whom 11 received bone marrow transplantation (BMT) and 24 peripheral blood stem cell transplantation (PBSCT). Conditioning regimens was TBI (total-body irradiation) + CY (CTX) protocol in 8 patients and BU/CY protocol in 27 patients. The average follow-up was 48 months (range 7 - 108 months).
RESULTS34 (97.1%) patients were successfully engrafted. Among them, 21 patients (60.0%) had three years disease-free (DFS) survival. The overall 5-year survival (OS) was 57.1%. Two patients (5.7%) relapsed. Transplant-related mortality occurred in 12 patients. Hemorrhagic cystitis (HC) occurred in 5 patients and HVOD was observed in 1 patient. Acute graft-versus-host disease (aGVHD) occurred in 18 patients (51.4%), among them 7 patients (20.0%) were of grade III-IV. Chronic GVHD was in 17 patients (48.5%). There was no significant difference in 3-years DFS between BMT group and PBSCT group (54.5% vs. 62.5%, P > 0.05). The 3-year disease-free survival (DFS) was 42.9% in TBI/CY group and 55.6% in BU/CY group (P > 0.05). In univariate prognostic analysis model, the DFS at 3 years is 75% and 47.4% for < or =30 years patients and >30 years patients, respectively, P < 0.05. The 3-year DFS of patients with first chronic phase is higher than patients with advanced diseases (61.3% vs. 40%, P < 0. 05). The 3-year DFS in patients of grade I - II GVHD was higher than that in patients of grade III-IV GVHD (81.8% vs. 14.3%, P < 0.05).
CONCLUSIONThe patients who had transplantation done within 1 year after diagnosis during their first chronic phase of disease and who had low-grade GVHD have better prognosis. Those patients who had III-IV acute GVHD are prone to incorporate severe infection, which was a worse prognostic factor of allo-HSCT for chronic myelogenous leukemia.

The respiratory tract is primary contact site of the body and environment,and it is ventilated by 10-20 thousand liters of air per day.Inevitably,the respiratory system comes into contact with airborne microbes,which contain the disease-causing pathogens.Airway epithelial cells (AECs) are known to have innate sensor functions,which are similar to the "professional" immune cells,such as alveolar macrophage and sub-or intra-epithelial dendritic cells (DCs).Thus AECs are able to detect invading microbial danger including different types of respiratory viruses,and mount a potent host response,for example,activating type Ⅰ interferon signaling pathway genes.To avoid chronic inflammation and maintain the immunological homeostasis,the pulmonary system has developed intrinsic mechanisms to control local immune responses.Most recently,the role of AECs in control of local immunity has gained much attention,as 1) AECs express the pattern recognition receptors (PRRs),such as Toll-like receptors,retinoic acid inducible gene Ⅰ (RIG-Ⅰ)-like receptor,and so on,thus AECs are equipped to Participate in innate detection of microbial encounter;2) To keep immunological homeostasis in the respiratory tract,AECs behave not only as innate immune sensors but also as immune modulators in parallel,through modulating the sensitivity of innate immune sensing of both AECs per se and sub-or intra-epithelial immune cells;3) Loss of modularity capacity of AECs might be involved in the development of chronic airway diseases.In present review,how the AECs act will be intensively discussed in response to respiratory viruses and modulate the local immunity through cis-and trans-factors (direct and indirect factors),as well as the consequence of impairment of this control of local immunity,in the development and exacerbation of airway diseases,such as acute and chronic rhinosinusitis.

Background:
Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS) in remission. The primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7 mg and 14 mg) in the subgroup of Chinese patients with relapsing MS included in the TOWER study.
Methods:
TOWER was a multicenter, multinational, randomized, double-blind, parallel-group (three groups), placebo-controlled study. This subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7 mg (n = 51), teriflunomide 14 mg (n = 43), or placebo (n = 54).
Results:
Of the 148 patients in the intent-to-treat population, adjusted annualized relapse rates were 0.63 (95% confidence interval [CI]: 0.44, 0.92) in the placebo group, 0.48 (95% CI: 0.33, 0.70) in the teriflunomide 7 mg group, and 0.18 (95% CI: 0.09, 0.36) in the teriflunomide 14 mg group; this corresponded to a significant relative risk reduction in the teriflunomide 14 mg group versus placebo (-71.2%, P = 0.0012). Teriflunomide 14 mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio: 0.319, P = 0.1194). There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs; 72.2% in the placebo group, 74.5% in the teriflunomide 7 mg group, and 69.8% in the teriflunomide 14 mg group); corresponding proportions for serious adverse events were 11.1%, 3.9%, and 11.6%, respectively. The most frequently reported TEAEs with teriflunomide versus placebo were neutropenia, increased alanine aminotransferase, and hair thinning.
Conclusions:
Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER trial. Teriflunomide has the potential to meet unmet medical needs for MS patients in China.
