Objective:Primary gastric diffuse large B-cell lymphoma (PGLBCL) is a highly common subtype of extranodal non-Hodgkin lymphoma. We analyzed the disease's clinical features and prognosis to guide better treatment. Methods:We retrospectively collect-ed data from PGLBCL cases seen from January 1999 to March 2012 in one cancer center. We then analyzed the demographic character-istics, clinical stage, histological diagnosis, complications, treatment, and prognostic characteristics of such patients. Results:A total of 126 patients with median age of 49 years old (range:16-81 years) were included in the study. The male-to-female ratio was 68:58. A to-tal of 96 patients were pathologically diagnosed with pure diffuse large B-cell lymphoma (DLBCL), 27 with mucosa-assouated lymphoid (MALT) component, and 3 with plasmacytoid differentiation. Meanwhile, 90%of the patients were in the early stage of the disease. For the early-stage patients, treatment strategy included surgery+chemotherapy ± radiotherapy for 38 cases, chemoradiotherapy for 39 cases, chemotherapy alone for 37 cases, and surgery alone for 1 case. Under a median follow up of 48 months, the 4-year progres-sion free survival (PFS) and overall ourvival (OS) rate of the whole group were 75.6%and 82.7%, respectively. PFS rates for early and advanced stage patients were 77%and 41.7%(P=0.005), respectively. For the early-stage patients treated with chemotherapy alone, chemoradiotherapy, and surgery with therapy, the PFS rates were 67.3%, 77.8%, and 77.8%(P=0.588), respectively. The patients with international prognostic index (IPI) score of 0, 1, and>1 achieved PFS of 85.4%, 74.4%, and 55.6%(P=0.011), respectively. The PFS rates were 81.2%and 66.1%(P=0.018) for stagesⅠandⅡ, respectively, and 86.6%and 63.3%(P=0.006) for the normal and elevated LDH levels, respectively. The pathological type of pure DLBCL or a MALT component, GCB or non-GCB origin, and age more than 60 years old were not associated with prognosis. Conclusion:The majority of the PGLBCL patients were in the early stage of disease, but the outcome of early-stage disease was favorable. Surgery did not improve outcomes. Univariate analysis demonstrated that IPI score>1, stageⅡdisease, and elevated LDH levels were associated with poor prognosis in the early-stage patient.

AIMTo establish a comprehensive HPLC analytical method of Huanglianjiedu decoction.

METHODSThis study was performed by HPLC-UV/MS to identify the chemical constituents of the whole and individual herbs of the "Huanglianjiedu decoction". Zorbax Extend C18 (150 mm x 4. 6 mm ID, 5 microm) column was used; the mobile phase was composed of acetonitrile (A) and water (B, with 0.5% acetic acid) with gradient elution; the flow rate was 1.0 mL x min(-1) and the column temperature was setup at 25 degrees C. The detection wavelength was 254 nm.

RESULTSThe chromatogram of Huanglianjiedu decoction showed 21 main peaks. Peaks 1, 2, 5 and 18 were from Gardenia jasminoides Ellis, Peaks 8, 13, 14, 15, 16, 17, 19 and 21 from Scutellaria baicalensis Georgi. While 10 from Coptis chinensis Franch and 20 from Phellodendron amurense Rupr., Peaks 3, 4, 6, 9, 11 and 12 came from them together. Peak 7 presented in the chromatograms of the herbs except Gardenia jasminoides Ellis. By comparison of the retention time, the on-line UV spectra and MS spectra, 11 peaks were identified as 5 (geniposide), 9 (jatrorrhizine), 10 (coptisine), 11 (palmatine), 12 (berberine), 13 (baicalin), 15 (oroxin A), 17 (wogonoside), 19 (baicalein), 20 (obaculactone), 21 (wogonin), then eight of them were quantified by HPLC-UV.

CONCLUSIONThe method could represent the characteristics of Huanglianjiedu decoction, and it could be used to evaluate the quality and quantity of Huanglianjiedu decoction. It distinguished between Coptis chinensis Franch and Phellodendron amurense Rupr. by HPLC for the first time.

OBJECTIVETo investigate the co-effect of Demand-control-support (DCS) model and Effort-reward Imbalance (ERI) model on the risk estimation of depression in humans in comparison with the effects when they are used respectively.

METHODSA total of 3 632 males and 1 706 females from 13 factories and companies in Henan province were recruited in this cross-sectional study. Perceived job stress was evaluated with the Job Content Questionnaire and Effort-Reward Imbalance Questionnaire (Chinese version). Depressive symptoms were assessed by using the Center for Epidemiological Studies Depression Scale (CES-D).

RESULTSDC (demands/job control ratio) and ERI were shown to be independently associated with depressive symptoms. The outcome of low social support and overcommitment were similar. High DC and low social support (SS), high ERI and high overcommitment, and high DC and high ERI posed greater risks of depressive symptoms than each of them did alone. ERI model and SS model seem to be effective in estimating the risk of depressive symptoms if they are used respectively.

CONCLUSIONThe DC had better performance when it was used in combination with low SS. The effect on physical demands was better than on psychological demands. The combination of DCS and ERI models could improve the risk estimate of depressive symptoms in humans.

Objective To observe the dynamic changes of prevalence of Keshan disease (KD) in Hebei province from 1990 to 2007, to provide scientific basis for its prevention and treatment. Methods The surveillance data of KD was analyzed according to "the National Scheme of KD Surveillance and the Surveillance of KD" (W/T 78-1996) in Hebei province from 1990 to 2007 by the Institute for Prevention of Endemic Disease in Hebei Province Center for Disease Control and Prevention. The data included physical examination, electrocardiogram (ECG), the chest X-ray film of KD patients and the suspected patients, as well as selenium contents of hair collected in 1990, 1992 and 1999. Results No new cases of acute and subacute types of KD patients were found at the surveillance sites from 1990 to 2007. Thirty-five cases of new latent KD and one case of spontaneous chronic KD were identified respectively. Prevalence of chronic and latent KD ranged from 1.12% (8/713) to 8.18% (27/330) and 2.29% (19/831) to 8.20% (45/549) in Hebei province from 1990 to 2007, respectively. The prevalence of KD in children aged 3 - 14 years old and childbearing woman aged 20 - 45 years old decreased year by year, however population over 45 years old were more likely suffering from KD. The major abnormal changes of ECG in KD) patients were complete fight bundle branch block, ST-T change frequent premature ventricular contraction, and left anterior faseicular block. The prevalence of the heart enlargement in KD patients was 47.00% (211/449) averagely, and the prevalence of heart enlargement of medium grade increased remarkably after 2005 [28.57%(8/28) - 48.39%(15/31)]. The average mortality in chronic KD patients was 18.0%(18/100) from 1990 to 2007. Conclusions The prevalence of KD decreased slowly in Hebei province. Hebei province is still the region with higher prevalence of KD around the country, and the tasks of prevention and treatment of KD is still urgent. Enhancing the surveillance of of KD and carrying out management and treatment of KD patients should be emphasized in the future.

Objective To investigate the change of 14-3-3 protein in cerebrospinal fluid (CSF) in different types of meningoencephalitis in children and its value in judging brain injury.Methods CSF 14-3-3 protein bands were detected by means of Western blot in 22 patients with viral meningoencephalitis and 20 cases of purulent meningoencephalitis and with 15 cases of febrile seizures as the control group from Jul.2009 to Jun.2010,and in addition,the quantitative detection of 14-3-3 protein was done by way of ELISA.Correlation was analyzed between the clinical manifestations,prognosis,EEG,head CT or MRI and the changes of 14-3-3 protein.Results The positive rate of 14-3-3 protein in cases of purulent meningitis was 65.0(13/22 cases),higher than viral meningoencephalitis group(27.3％,6/22 cases),and the difference was significant.In the quantitative detection,14-3-3 protein was increased in both the purulent meningitis [(5.6 + 0.2) μg/L] and viral encephalitis groups[(3.2 + 0.3) μg/L] compared with the control group [(0.9 + 0.1) μg/L].After treatment,14-3-3 proteins were less than before in the purulent meningitis and viral meningoencephalitis groups.In the cases with severe clinical manifestations and severe injury brain suggested by imaging and EEG,the 14-3-3 protein in cerebrospinal fluid was elevated;and the prognosis of the cases with increased 14-3-3 protein was poor,as a result of epilepsy,death and so on.Conclusions 14-3-3 protein in the CSF increases with disease severity,so to a certain extent,it can be used to identify viral meningitis and purulent meningitis.
