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 characterize the sites of distant recurrence and clinical outcomes in a cohort of Chinese patients with metastatic triple-negative breast cancer (TNBC).
METHODSOne hundred and thirty-four patients with metastatic TNBC treated at Cancer Hospital of CAMS from January 1999 to December 2007 were included in this study. The clinicopathological features and long-term survival of the patients were retrospectively analyzed.
RESULTSThe median age of the patients was 45 years. Most patients (72.7%) had a higher predilection for visceral metastasis and early recurrence within the first two years of follow-up. Six patients (4.5%) presented with stage IV disease, 14 patients were diagnosed with locoregional recurrence after mastectomy, 75 patients with distant metastases, and 45 patients with both locoregional recurrence and distant metastasis. The most common site of first recurrence was the lung, and 62(51.7%)of the patients had more than two sites of metastasis. By July 30, 2009, 75 patients died of breast cancer (56.0%). The median overall survival (OS) was 26.5 months [95% confidence interval (CI), 20.5 - 32.6 months]. The 1-, 3- and 5-year overall survivals (OS) were 80.9%,37.1% and 30.1%, respectively. The median overall survival time of 58 patients with single site of metastasis was 28.5 months, longer than that of patients with more than two sites of metastases. Patients whose initial distant recurrence was bone metastasis only (7 patients) had better prognosis, with a median OS of 84.2 months. The median OS (28.5 vs. 12.6 months, P = 0.0001) differed significantly between patients who received first-line chemotherapy and those who did not. Forty-five of the 96 patients with measurable disease achieved complete/partial response (CR/PR), 39 patients had stable disease (SD), and 12 patients had disease progression (PD). The median OS was 36.1 months in patients with CR/PR, 20.8 months with SD, and 14 months with PD, respectively. The median OS of patients with CR/PR was significantly longer than that of patients with SD/PD (P = 0.0108). Distant metastasis, first-line chemotherapy and clinical response were significantly related with OS by univariate analysis. Furthermore, first-line chemotherapy and the clinical response were demonstrated to be an independent prognostic factor by multivariate analysis.
CONCLUSIONSRecurrence risk and mortality are considerably higher in TNBC patients within the early years of follow-up. TNBC patients have a higher risk of multiple and visceral metastases, and poorer survival, which might attribute to its aggressive clinical behavior and lack of effective regimens. Our findings also suggest that chemotherapy can effectively improve the clinical outcome of those patients.

OBJECTIVETo understand the epidemiological, clinical and etiological characteristics of an Echovirus type 6 meningitis outbreak in Jinzhai county, Liu'an city in Anhui, and to find out the proper way in controlling the aseptic meningitis outbreak.
METHODSA surveillance system for aseptic meningitis was established in Jinzhai to confirm the case definition. Stool or cerebrospinal fluid (CSF) specimens from some cases were collected for entero-viruses isolation and identification. Case-control study was conducted. The case group involved patients while the controls would include: patients' classmate with same gender and the age difference was not over one year. Neutralization antibody in serum specimens were collected and tested in cases and in healthy people.
RESULTS105 cases were distributed in 17 of the 30 towns in Jinzhai county while 41.0% of the cases were in Banzhuyuan town with an incidence rate of 203/10(5). Cases were clustered by school and classroom with age ranging from 3 to 15 years old and the highest as 10.9/10(5) in the 6 to 10 group. The incidence in males was 24.2/10(5) compared to 8.4/10(5) in females. The main clinic characteristics of cases were: fever, headache and vomiting. Echovirus type 6 from 25 of the 72 CSF samples (35%) was isolated. When comparing the cases group with control group, the OR of drinking home-made beverages was 4.1 (95% CI: 1.4-12.0), especially the beverages sacked by plastic bag: 3.3 (95% CI: 1.3-8.8). 6 out of 7 workers engaging in producing home-made beverages were detected to have carried Echovirus type 6 from their stool specimens. The Echovirus type 6 neutralization antibody positive rate in cases (73.5%) was significantly higher than that in 100 healthy people (46.0%) (X2 = 12. 526, P = 0.000).
CONCLUSIONThis episode of meningitis outbreak was caused by Echovirus type 6. The proportion of drinking home-made beverages, especially the beverages sacked by plastic bag in cases group was higher than in control group.

OBJECTIVETo investigate the role of ataxia telangiectasis mutated (ATM) gene in the oncogenesis and progression of oral squamous cell carcinoma (OSCC).
METHODSA total of 61 formalin-fixed and paraffin-embedded samples were obtained from patients with hyperkeratosis, oral leukoplakia, OSCC and normal healthy controls. The expression of ATM protein in all of the samples was investigated by streptavidin-peroxidase immunohistochemistry assay. PCR was also performed to detect the loss of heterozygosity (LOH) in D11s2179 of ATM gene. The correlations between ATM and the clinical and histopathological characteristics were also investigated.
RESULTSThe results indicated that the ATM expression was increased in oral premalignant lesions (P<0.05). For OSCC, 68.8% samples showed normal or increased ATM expression, while 31.3% had decreased or absent ATM expression. Significant differences were found between the group of decreased or absent ATM expression and that of normal or increased expression over the histopathological grade and lymph node metastasis state. PCR results displayed that none of the samples from oral premalignant lesions showed abnormal changes, while 3 of the OSCC (9.38%) showed loss of heterozygosity (LOH) and 2 (6.25%) with microsatellite instability (MSI). Those 3 samples of LOH showed absent ATM expression.
CONCLUSIONThese findings indicated that the over expression of ATM may contribute to prevent carcinogenesis of OSCC. ATM inactivation may be one of the genetic alterations of the molecular progression of OSCC.
