Autophagy is a classical regulatory mechanism of energy metabolism and self-update system in the maintenance of the intracellular homeostasis and cell development. Autophagy has been recently found to play a role in tumor development. Autophagy regulates tumor formation, proliferation, metastasis, and metabolism. At the same time, the anticancer drugs formed with autophagic mediators have been used in the treatment, which suggested that improving autophagy activity to inhibit tumor has become a new way for cancer treatment of cancer patients. This article gives an overview of the regulatory mechanism of autophagy, the relationship between autophagy and tumor, and tumor therapy by targeting autophagy.

Objective To study the clinical and laboratory features of the patients with immunorelated pancytopenia(IRP).Methods The risk factors,manifestations,blood cell counts,bone marrow phenotypes,autoantibodies and immunosuppressive therapy response of 72 patients with IRP were analyzed.Then they were followed up for(6 ~36)months,to see their long-term outcome and the prognostic factors.Results The infection,anaphylaxis and pregnancy were highly suspected to be the risk factors of IRP.Most of these patients were with pancytopenia72.2%(52/72);91.7%(66/72)of them were anemic with large or normal MCV;75.0%(54/72)of them were with leukopenia;18.1%(13/72)of them had fever.Thrombocytopenia was common,but serious bleeding rare.68.1% of these cases were with normal or decreased bone marrow cellularities and increased normoblasts.They were all found to have positive results of bone marrow mononuclear cell Coombs test,negative results of routine hemolysis tests and no evidence of malignant clonal hematopoiesis.42.9%(18/42)of these patients had C3 decreased,and 19.0%(8/42)C4 decreased.Immunosuppressive therapy was administered to 72 IRP patients.The response rate at 36 months was 87.5%(28/32).Conclusion IRP is a blood disease induced by acquired autoantibodies mediated bone marrow inhibition or destruction.It manifests pancytopenia with relative higher percentages of reticulocytes and neutrophils,and responds well to immunosuppressive therapy.

Objective To explore the clinical features of sev er e aplastic anemia (SAA) patients with chronic hepatitis B virus (HBV) infection.Methods 737 SAA cases newly diagnosed in the institute of Hemat ology and Blood Disease Hospital,CAMS in recent 13 years (1991 ~ 2003) were anal yzed.The ratio of SAA patients with chronic hepatitis B (21 cases,group Ⅰ) in them was investigated.A case-control study was undertaken to investigate the di fferences of clinical and laboratory features、therapeutic effectiveness and pro gnosis between SAA patients with chronic HBV infection \[the cases with chronic hepatitis B and those with antibodies to hepatitis virus B (23 cases,group Ⅱ )\] and SAA control group (42 cases,group Ⅲ ).Results ①The ratio of SAA patients with chronic hepatitis B in all SAA was 2.8%.②There was no significant difference of clinical features am ong them before treatment.③The recovery of PB counts、bone marrow hematopoiesis of group Ⅰ was slower than that of group Ⅱ and group Ⅲ after treatment.Th e percentage of CD8 + cells of group Ⅰor Ⅲwas significantly higher than that of group Ⅱ (P

Objective To understand the drinking water quality in the rural areas in Jiading, Shanghai. Methods In September, 2006, the drinking water samples from water plants and tap water were collected, then the water quality was analyzed and assessed according to the related standards and regulations. Results 84.56% of the rural population drank the surface water, 15.44% drank the ground water. Among 99.85% of the centralized water supply systems, the drinking water (surface water) was treated; among 0.15%, the drinking water (ground water) was only treated by decreasing iron and manganese. Source water and treated water quality had been greatly improved. Conclusion Intensive management of drinking water is very important to ensure the drinking water quality in the rural areas.
