Objective To evaluate the relationship between the amount of grafted cells and the incidence of acute graft versus host disease (aGVHD) after haploid hematopoietic stem cell transplantation (haplo-HSCT). Methods Data of 68 patients who underwent haplo-HSCT from Jan 2009 to Dec 2013 were analyzed retrospectively. Influences of different factors on the incidence of Ⅲ-Ⅳ degree of aGVHD after HSCT were evaluated. Results 68 patients including 42 males and 26 females were 5/10-9/10 HLA match with 19 father donors, 24 mother donors, 16 sibling donors and 9 children donors. 51 patients not suffered Ⅲ-Ⅳdegree of aGVHD included 32 males and 19 females with the mean age of 20 years old (5-55 years old). 17 patients sufferedⅢ-Ⅳdegree of aGVHD including 10 males and 7 females with the mean age of 23 years old (5-54 years old). There were no significant differences in the amount of the grafted mononuclear cells (MNC) and CD34+cells, and the white blood cell counts (WBC) and platelet count (Plt) recovered time between two groups (P>0.05). However, MNC number was related to CD34+cell number (P<0.05) and WBC recover time (P<0.05), and the CD34+cells number was related to WBC and Plt recover time (P< 0.05). Conclusion The incidence of Ⅲ-Ⅳ degree of aGVHD is unrelated to the amount of grafted MNC, and CD34+cells.

OBJECTIVE: To explore the effection of the pulmonary function of patients of chronic rhinosinusitis (CRS) with asthma which treated with endoscopic sinus surgery (ESS) based comprehensive treatment. METHOD: There were 50 cases of chronic rhinosinusitis with asthma whom met the study criteria. 35 cases enrolled in the tri al group, which treated with endoscopic sinus surgery, and routine perioperative tratment. Another 15 cases as control group which underwent conservative treatment. Both groups underwent the rule treatment of asthma. The main monitoring indexes, which included visual analogue scale (VAS) score, endoscopic Lund-Kennedy score, control of asthma symptoms, the pulmonary function which involved forced expiratory volume in first second (FEV1), forced vital capacity (FVC), the ratio of forced expiratory volume in first second and forced vital capacity (FEV1/FVC) and peak expiratory flow (PEF), were measured in the patients of each groups before surgery, follow-up for 1 year and 3-year. RESULT: Our study found that the VAS score of CRS with asthma was significantly negatively correlated with FEV1 and PEF (P < 0.05), endoscopic Lund-Kennedy score was significantly negatively correlated with PEF (P < 0.05); After the trial group underwent ESS based comprehensive treatment, the improvement of VAS score and endoscopic Lund-Kennedy score of postoperative compared with preoperative and the same period in the control group were significantly (P < 0.05). The difference of the postoperative asthma control rate of trial group after 1 year and after 3 years, respectively, compared with the same period control group were statistically significant (P < 0.05). The preoperative FEV1, FVC, FEV1/FVC and PEF of trial group compared with preoperative were significantly (P < 0.05). Even the difference of them compared with the same period control group were significantly (P < 0.05), except the FVC in the follow-up 3 years (P = 0.088). CONCLUSION The CRS may aggravate asthma symptoms and affect negatively the pulmonary function, and poor asthma control or aggravate may exacerbate the CRS in the course of CRS with asthma patient. With ESS based on combined therapy, it can improve the condition of CRS significantly and improve the control of asthma symptoms and pulmonary function else.

OBJECTIVETo explore a new method of establishing HepG2 cell model of steatosis and observe the expression and significance of nuclear factor erythroid-2p45-related factor 2(Nrf2)/antioxidative response element (ARE) pathway related factors in HepG2 cells of steatosis.

METHODSHepG2 cells were induced with DMEM containing 25% fetal bovine serum, 0.1% MCT/LCT Fat Emulsion and 0.1 mmol/L free fatty acid (FFA) at different stages and the control group cells were cultured with normal DMEM medium. After the cell models were successfully established, lipid droplets in cytoplasm were observed with Oil Red 0 staining, and the triglyceride (TG) accumulation in HepG2 cells were tested by biochemical assay. Intracellular reactive oxygen species (ROS) concentration were detected by flow cytometry. Nitric oxide (NO), superoxide dismutase(SOD), malonyldialdehyde(MDA) and glutathione peroxidase(GSH-Px) were tested by biological reagent kit, while the protein expression of nuclear factor erythroid-2p45-related factor 2(Nrf2), heme oxygenase-1 (HO-1) and

NAD(P)Hquinone oxidoreductase-1(NQO1) were analyzed by Western blot.

RESULTSCompared with that in the control group, red cytoplasmic lipid droplets were visible in model group; TG,ROS, NO, MDA concentration (P < 0.05, P < 0.01) and the protein expression of Nrf2, HO-1 and NQO1 (P < 0.05, P < 0.01)were significantly higher in model group, while SOD, GSH-Px concentration reduced significantly (P < 0.01).

CONCLUSIONThe in vitro cell model of steatosis and oxidative stress was successfully established. The activation of Nrf2/ARE pathway related factors maybe relevant to the overreaction of oxidative stress in HepG2 cells of steatosis.

OBJECTIVETo investigate the amplification of EMS1 gene in the carcinogenesis of oral mucosa.

METHODSA total of 78 subjects, including 30 patients with oral leukoplakia (OLK), 33 with oral squamous cell carcinoma (OSCC), and 15 healthy controls, were studied. By using microdissection method, we obtained normal mucosa, hyperplastic epithelia, mild-dysplastic epithelia, moderate-dysplastic epithelia, severe-dysplastic epithelia and primary OSCC tissue. Then we analyzed EMS1 amplification by using differential PCR.

RESULTSEMS1 amplification began from moderate-dysplastic epithelia and occurred in 20.0% OLK cases and 57.6% OSCC cases. In the progress of OSCC, no gene amplification was observed in normal tissues, non-dysplastic OLK and mild-dysplastic OLK, while in the cases with metastasis, amplification frequency increased significantly (P = 0.015).

CONCLUSIONSEMS1 amplification parallels with the progress of oral carcinogenesis, indicating their potential roles in oral carcinogenesis.

OBJECTIVETo improve the accuracy and sensitivity of cell membrane chromatography (CMC) and evaluate the feasibility of CMC in the study of subtype receptors.

METHODSPlasmids were used to transfer alpha(1B)-AR cDNA into human embryonic kidney 293 (HEK293) cell lines to obtain cell lines stably overexpressing the subtype receptors. HEK293 alpha(1B) cell membrane stationary phase (CMSP) was prepared by immobilizing the cell membrane on silica. The retention time of 9 alpha(1)-adrenoceptor ligands and capacity factors(kappa'(HEK293 alpha1B)) were calculated. The capacity factors of rat liver tissue and primary cultured rat hepatocytes were also calculated for a correlation analysis.

RESULTSThe calculated capacity factors (kappa') were positively correlated to the published pKi values. The affinity rank orders were identical. The longest retention of the 9 alpha(1)-adrenoceptor ligands occurred on CMSP prepared with HEK293 alpha(1B) cell lines, while CMSP obtained from rat liver tissue showed the shortest retention of the ligands.

CONCLUSIONCMC proves practical in the study of the subtype adrenoceptors. The accuracy and sensitivity of CMC can be improved using HEK293 alpha(1B) cell membrane.

OBJECTIVESTo investigate the serum leptin and adiponectin levels in nonalcoholic fatty liver disease (NAFLD) patients, and their relationship with insulin resistance.

METHODSA total of 120 cases were enrolled and divided into two groups: NAFLD group (n = 60) and normal control group (n = 60). The serum levels of leptin and adiponectin were measured by ELISA. The body mass index (BMI), waist-to-hip ratio (WHR), triglyceride (TG), total cholesterol (Tchol), high-density lipoprotein cholesterol (HDL-C) , aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), fasting blood glucose (FBG) and HOMA-IR (homeostasis model assessment insulin resistance) were detected and analyzed.

RESULTSCompared with control group, the serum leptin level in NAFLD group was Significantly higher [(12.37+/-1.99) microg/L vs (5.20+/-1.03) microg/L, P less than 0.01], while the serum adiponectin level was significantly lower [(12.69+/-2.83) mg/L vs (22.83+/-4.61) mg/L, P less than 0.01]. HOMA-IR was also much higher in NAFLD group than that in control group[(4.86+/-0.63) vs (1.91+/-0.41), P less than 0.01]. Logistic regression analysis showed that leptin was positively correlated with WHR (beta value = 8.175, P less than 0.01), HOMA-IR (beta value = 0.974, P less than 0.01 ), FBG (beta value = 0.564, P less than 0.01 ). In contrast, adiponectin inversely associated with HOMA-IR (beta value = -0.495, P less than 0.01 ) and BMI (beta value = -0.314, P less than 0.01) respectively.

CONCLUSIONThe increased serum leptin level and decreased serum adiponectin level in NAFLD patients independently associated with HOMA-IR.
