Objective To analyze the changing process and development trend of deaths (mortality)in patients with viral hepatitis after the use of the Internet-based National Notifiable Infectious Disease Reporting System.Methods Descriptive statistical and moving average methods were employed to analyze the infectious disease reports released by the Chinese government during 1992-2013,and the changing process and development trend of deaths (mortality)in patients with viral hepatitis in China over the past 10 years were investigated.Re-sults The annual deaths (mortality)in patients with viral hepatitis showed a decreasing trend.The deaths (mortality)from hepatitis B showed a slight declining trend,accounting for a great proportion (over 70%)of the deaths (mortality)from viral hepatitis;the deaths (mortality)from hepatitis C had shown a slight downward trend since 2007;the deaths (mortality)from hepatitis A and unclassified hepati-tis decreased to different extents;the deaths (mortality)from hepatitis E remained at a relatively low level.Conclusion The treatment of viral hepatitis has been gradually improved in China and the public awareness of viral hepatitis keeps increasing.However,much attention still needs to be given to the prevention and treatment of viral hepatitis,especially hepatitis B and C,by the government.

Objective To explore the relationship between the change of serum ferritin level and acute lung injury.Methods 192 cases living hospital patients with critical factor of acute lung injury were divided into two groups:acute lung injury group(study group,52 cases)and having critical factor of acute lung injury but not devel- oped acute lung injury group(control group,140 cases).50 people at the same time were selected as normal group. Serum ferritin level were measured,and their correlation between groups were analyzed.Results The serum ferritin level in study group[female(354.7?9.8)/,g/L,male(789.7?30.8)tag/L]increased significantly as compared wit h that in control group[female(182.7?7.8)/,g/L,male(312.5?1.9)?g/L](P

ObjectiveTo explore the tumor igenic property of side population cells (SP) from human gallbladder carcinoma cell line GBC-SD. Methods SP and non-SP cells were isolated from GBC-SD staining with Hoechst33342 dye by fluorescence-activated cell sorting (FACS). The soft agar clonal assay and xenograft assay were performed to characterize tumorigenic property of side population cells in vitro and in vivo, respectively. The percentage of SP cells was analyzed by FACS in 5 hu man gallbladder carcinoma specimens. ResultsThe percentage of SP cells accounted for approximately 0.87 ％ of GBC-SD cells. The clone-formed rates of SP was more frequent than that of non-SP cells (14.74％ ± 3.53％ vs 5.17％ ± 1.05％), there was statistically significant difference (t =2.75,P＜0. 05). SP cells could generate tumors with as few as 5 × 103 cells (four of seven animals), whereas at least 1 × 105 non-SP cells were needed to form a tumor (one of seven animals). Re-analysis of SPderived tumors by FACS showed that SP cells under in vivo conditions also have the capacity to regenerate the SP and non-SP fractions. Besides, analysis of Hoechst33342 revealed s small fraction of SP cells, ranging from 0. 27％ to 2.3％ in gallbladder carcinoma specimens. ConclusionSP cells from GBC-SD are highly tumorigenic similar as the cancer stem cells.

Objective To investigate the drug resistance of side population cells in human gallbladder cancer cell line GBC-SD and explore its mechanism. Methods Drug sensitivity assays of 5chemotherapeutic agents were performed on side population cells (SP) and non-SP cells of GBC-SD.GBC-SD was cultured and then treated with the chemotherapeutic agent gemcitabine. The frequency of SP by FACS was measured. RT-PCR and Western blotting were used to detect the expression of AB-CG2 in both the SP and the corresponding non-SP subsets. Results After 1 d treatment with 4 chemotherapeutic agents (gemcitabine, cisplatin, 5-fluorouracil and mitoxantrone) in IC50 concentration to GBC-SD cell line, the reproductive ability of SP was higher than that of non-SP (P<0.05). However, statistical significance was not achieved when compared with epirubicin (P>0.05). The percentage of SP in GBC-SD treated with chemotherapeutic agent gemcitabine after 3 weeks was sharply elevated by FACS (8.02% ±0.13% vs 0.62% ±0.08%, P<0.05), and the expression of ABCG2mRNA and protein were increased in SP as compared with non-SP. Conclusion SP from human gallbladder cancer cell line GBC-SD, like stem cell, showed a heighten resistance to drugs. Increased expression of ABCG2 was largely responsible for the multi-drug resistance.

Objective · To investigate the changes of neutrophils and lymphocytes during chemotherapy courses in children with high-risk neuroblastoma, as well as severe infection rate and its relationship with combination chemotherapy regimens in order to provide guidance to prevent infection in these children. Methods · A total of 45 cases of children with high-risk neuroblastoma, who were hospitalized in Xinhua Hospital from July 2012 to September 2015 were recruited. Reactions after chemotherapy and the results of routine blood tests on every 5 days during the whole chemotherapy circles were recorded. Follow-up visits were carried out to learn the infection occurrence. Results · The counts of neutrophils and lymphocytes dropped to the minimum at the 10th day or so during chemotherapy, then rised near the 15th day. Infections were negatively correlated with the numbers of neutrophils (r =-0.245) and lymphocytes (r=-0.227) at the 10th day. Persistent lymphopenia occured after the forth course of chemotherapy. Rate of grade Ⅳ bone marrow suppression after chemotherapy was 90%, and severe infection rate was 15.5%. There were significant differences in the rates of grade Ⅲ bone marrow suppression (P=0.008), grade Ⅳ bone marrow suppression (P=0.001) and severe infection (P=0.010) among the 3 combination chemotherapy regimens used in high-risk neuroblastoma children. Conclusion · Children with high-risk neuroblastoma had obviously high rates of bone marrow suppression and severe infection after chemotherapy, especially after cyclophosphamide+doxorubicin+vincristine regimens. More attention should be paid to this group of children and preventive measures were worthy of taking into account.

Objective: To observe the therapeutic efficacy of astragalus polysaccharide (APS) in combination with three-dimensional conformal radiotherapy (3D-CRT) for elderly patients with non-small cell lung cancer (NSCLC). Methods: A total of 80 elderly patients with I～IV stage NSCLC were randomly divided into two groups. The 40 patients in the therapeutic group received radiotherapy in combination with APS. The 40 patients in the control group received radiotherapy alone. Both groups received 3D-CRT with a total dose of 50～ 70Gy, 2.0Gy/fraction, once a day, 5 times per week. The patients in the therapeutic group were treated with radiotherapy combined with injection of APS (250mg in 5% glucose) or normal saline (500 mL) intravenously once a day until the end of radiotherapy. The short-term efficacy and patients' quality of life were evaluated. The T-lymphocyte subpopulation and peripheral blood leukocyte count were also measured after treatment. Results: The short-term effective rates of the therapeutic group and the control group were 87.5% and 72.5%, respectively, without significant difference between the two groups (P＞0.05). The decrease of peripheral blood leukocyte count after treatment in the control group was significant (P＜0.05). In the therapeutic group, the T-lymphocyte subsets CD8 and CD4/CD8 were improved after treatment, with a significant difference (P＜ 0.05). But in the control group, no significant changes in T-lymphocyte subsets CD8 and CD4/CD8 were observed after treatment (P＞0.05). Patients' quality of life in the therapeutic group was superior to that in the control group, with a significant difference (P＜0.05). Conclusion: APS in combination with 3D-CRT can reduce the side effects of radiation and improve the quality of life of elderly patients with NSCLC.
