Objective To study the effects of matrine on accumulation of ? globin mRNA and induction of erythroid differentiation in K562 cells in vitro.Methods K562 cells were cultured for 6 days with different concentration of matrine,viable cell counts were determined by trypan-blue dye exdusion test. Erythroid differentiation was evaluated by percentage of benzidine-positive cells at different days after culture. Morphological changes were observed under microscope after Wright-Gimesa staining; ? globin mRNA was quantitative by real time quantitative reverse transcript polymerase chain reaction(RT-PCR).Results Different concentrations of matrine inhibited proliferation of K562 cells in dose-dependent manner; otherwise, K562 cells were successfully induced by erythroid differentiation with matrine. After treatment with matrine, percentage of benzidine-positive cells significantly increased from 0.7% to 15.7% and characteristic changes of erythroid differentiation in the cell morphology were observed, G? globin mRNA had a preferential increase (2.7 fold)in K562 cells. Conclusions Matrine accumulation G? globin mRNA and induced erythroid differentiation of K562 cells. The results provides an experimental evidence for the pharmacological therapy of hematological diseases associated with a failure in the expression of normal ? globin genes.

Objective To survey the arsenic content of drinking water in Jingzhou City, to provide basis for prevention and control of endemic arsenic disease. Methods According to historical data, the .arsenic content of water was detected in 357 villages from 6 counties of Jianglin, Songzi, Gongan, Shishou, Jianli, Honghushi in Jinzhou City in 2007 and 2008, The past have been found to have high arsenic water villages, villages known to have high concentration of arsenic were put into census. Villages not found to have high-arsenic wells were sampled 10 percent of the whole water resources at five directions of east, west, south, north and the center. Using sampling investigation, water arsenic was determined by half -quantitative fast reagent kit. All samples of water with arsenic exceeding the standard were re-determined using silver diethyl dithiocarbamate using silver diethyl dithiocarbamate colorimetric mothod. Survey on the disease was carried out in the villages with arsenic exeeeding the standard. Results All 6074 water samples was inspected. Arsenic in 210 samples outnumbered 0.05 mg/L, 51 natural villages were high arsenic areas;The maximum level of arsenic content in drinking water was 0.7 mg/L 3.2% (152/4784) of the wells no deeper that 30 meters and 4.9%(58/1184) between 30 to 100 m had arsenic exceeding the standard The water arsenic content was normal when the wells was deeper that 100 m. The abnormal percentages of water arsenic was related with the depth of wells with a significant difference(χ2 = 12.29,P < 0.01). Medical examination 84 064 residents in 51 villages having high arsenic water 31 neighboring villages was made, No Patients was found suffering from endemic arsenic poisoning. Conclusions High arsenic source has been found in Jingzhou City ,but no endemic arsenic poisoning patient in Jingzhou City. It is suggested that necessary preventive measures should be taken in high arsenic area, low-arsenic water should be spotted or high arsenic water improved. Moreover, wells should be drilled for more than 100 meters or more in depth.

OBJECTIVETo investigate the clinicopathological features of primary gastrointestinal non-Hodgkin's lymphomas (PGI-NHL) and their prognostic values.

METHODSThe clinical and pathological data of 216 patients diagnosed as PGI-NHL from Zhejiang Cancer Hospital were analyzed retrospectively. χ² test, log-liner model analysis, COX proportional hazard regression analysis and Life-table survival analysis were used to analyze the survival status of the patients by SAS 8.2 software, and Log-rank test was performed to couple the overall survival rates with different prognostic factors.

RESULTSTotally, the age of onset was 8 to 89 years with the median age of 56.5 years. Male versus female was 1.27∶1(121∶95). The most frequently involved location was stomach (147 cases, 68.1%), followed by ileocecus (25 cases, 11.6%), large intestine (20 cases, 9.3%), small intestine (17 cases, 7.9%) and multiple GI involvement (5 cases, 2.3%). 182 cases were classified as B cell lymphomas, 22 cases as T cell lymphomas, and 12 cases not classified exactly due to insufficient data. The 3-year and 5-year survival rates of the patients were 69.4% and 53.3%, respectively. Univariate analysis revealed that age＞60 years, ECOG≥2, high LDH level, stage Ⅲ-Ⅳ, IPI≥2, T cell type and intestinal involvement were predictors for poor prognosis. IPI≥2, T cell type and intestinal involvement were independent adverse predictors for prognosis by multiple COX proportional hazard regression analysis. Among different treatment groups, cases received chemotherapy combined with local radiotherapy gained the best survival status.

CONCLUSIONB-cell lymphoma was the main pathological type in PGI-NHL; IPI≥2, T-cell type and intestinal involvement are independent adverse predictors for prognosis; chemotherapy combined with local radiotherapy might be the choice of approach for advanced stage and aggressive PGI-HNL.

Purpose To study the clinical features, immunophenotypes and prognostic factors of primary breast diffuse large B-celllymphoma (PBDLBCL). Methods The clinical pathological data of 49 cases of PBDLBCL during January 2006 to December 2016 were retrospectively analysed, and the basic clinical and pathologic data, pathologic types and the immunohistochemical slides by EnVision method for staining were summarized. Results 47 cases were women and 2 cases were men. The age ranged from 24 to 79 year old with the median age of 48 year old. On microscopic observation, tumor cells were large to medium-sized which characterized as diffuse infiltration between the lobules of mammary gland, around the duct, interstitial and fat tissue, some were single file cord pattern. The immunophenotype showed 37 cases were of non-GCB, 12 cases were GCB type. Ki-67 index were greater than 40％. According to Ann Arbor staging, 16 cases were stage I EA, 28 cases were stage Ⅱ EA, 5 cases were stage Ⅳ E. IPI score: 30 cases with 0 ～1 score, 10 cases with 2 score, 9 cases with 3 score. Patients were followed up from 5 to 146 months, The 3-year overall survival (OS) rate was 51.2％ and 5-year OS rate was 36.7％, Single factor analysis showed that there were statistically significant difference in clinical stage, levels of LDH, IPI score, BCL-2 protein expression, and BCL-6 protein expression in 3 and 5 years of OS rate. The multiple factor analysis of Cox regression showed that the increase of IPI risk classification was the independent adverse prognostic factor of primary breast diffuse large B-cell lymphoma. Conclusion The diagnosis of PBDLBCL is confirmed by pathological biopsy and immunohistochemical markers. The immunophenotype was mainly non-GCB type. Comprehensive treatment including surgery, chemotherapy and radiotherapy is appropriate. The prognosis should be comprehensively evaluated by multiple factors. IPI increase risk classification is the independent adverse prognostic factor.

OBJECTIVETo observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.

METHODSUrine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples. Contents of related biomarkers were analyzed by principal component analysis (PCA), partial least square discriminant analysis (PLS-DA), and urivariate statistical analysis.

RESULTSPLS-DA analysis showed that metabolites among CSG patients with PQDS/PWDHS and healthy volunteers could be mutually distinguished. Seven differentially identified metabolites were screened from urines of CSG patients with PQDS and healthy volunteers included glutamate, methionine, α-oxoglutarate, dimethylglycine, creatinine, taurine, and glucose. Four differentially identified metabolites were screened from urines of CSG patients with PWDHS and healthy volunteers included 2-hydroxybutyric acid, trimethylamine oxide, taurine, and hippuric acid. Eleven differentially identified metabolites were screened from urines of CSG patients with PQDS and PWDHS included fucose, β-hydroxybutyric acid, alanine, glutamate, methionine, succinic acid, citric acid, creatinine, glucose, hippuric acid, and lactic acid.

CONCLUSIONThe metabolic differences of CSG patients PQDS and PWDHS mainly manifested in glycometabolism, lipid metabolism, and amino acids catabolism, and 1H-NMR based metabonomics may be used in classified study of Chinese medical syndrome typing.
