OBJECTIVETo investigate the expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) plasma cells in the patients with multiple myeloma (MM), and explore the importance of Notch signaling pathway in the formation and progression of MM.
METHODSThirty three MM patients and 15 healthy controls were enrolled in this study. The expression of Notch1 on the membrane of bone marrow CD38(+)CD138(+) and CD38(+)CD138(-) plasma cells were analyzed by flow cytometry. The clinical data of MM patients were also analyzed.
RESULTSThe ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was (60.21 ± 25.06)% which was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients (39.84 ± 18.94)% (P = 0.000) and controls (38.34 ± 19.39)% (P = 0.004). There was no statistical difference between the two latter groups (P > 0.05). The expression of Notch1 on CD38(+)CD138(+)plasma cells from 24 newly diagnosed MM patients was correlated to the level of malignant plasma cells in there bone marrow (r = 0.914, P = 0.000), serum level of lactate dehydrogenase (LDH) (r = 0.754, P = 0.007), and β(2)-MG(r = 0.716, P = 0.013). The ratio of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients who had renal dysfunction was correlated to their abnormal serum creatinine levels. The expression of Notch1 on CD38(+)CD138(+) plasma cells from 17 MM patients who received VD (bortezamib and dexamethasone) chemotherapy was correlated to the ratio of plasma cell reduction after the first VD chemotherapy (r = 0.842, P = 0.000).
CONCLUSIONThe expression of Notch1 on the membrane of CD38(+)CD138(+) plasma cells of MM patients was significantly higher than those of CD38(+)CD138(-) plasma cells of MM patients and controls. Notch1 overexpressed plasma cells were sensitive to the early VD therapy, and correlated to the progression and long term outcome of MM.

BACKGROUNDProneurotrophins such as the precursor of nerve growth factor (proNGF) and the precursor of brain-derived neurotrophic factor (proBDNF) interacted with sortilin and p75(NTR) to form a complex capable of activating an apoptotic signaling. We found that the expression of p75(NTR) and sortilin was increased in ischemic retina induced by elevated intraocular pressure (IOP), but the protein expression changes of proNGF and proBDNF in the same situation were not clear. This study aimed to ascertain the protein expression changes of proNGF and proBDNF in ischemic retina induced by elevated IOP.
METHODSExpression of proBDNF and proNGF was examined by double-labeling immunochemistry in normal rat retina, examined using Western blotting and analyzed using statistical methods in ischemic retina induced by elevated IOP.
RESULTSImmunocytochemistry showed that the proBDNF expressed in the ganglion cell layer (GCL) while the proNGF primarily existed in both the nerve fiber layers (NFL) and large ganglion cell bodies of normal rat retina. Western blotting analysis demonstrated that the molecule weights of 28 kD (proBDNF)/25 kD (proNGF) band were increased significantly (P < 0.05) at days 3, 5 and 7 after retinal elevated-IOP-induced ischemia.
CONCLUSIONProBDNF expressed in the GCL and proNGF primarily presented in NFL and large ganglion cell bodies of normal rat retina, the protein expression forms of 28 kD proBDNF and 25 kD proNGF increased in ischemic retina induced by elevated IOP.

Gene editing is a kind of technologies that makes precise modification to the genome. It can be used to knock out/in and replace the specific DNA fragment, and make accurate gene editing on the genome level. The essence of the technique is the DNA sequence change with use of non homologous end link repair and homologous recombination repair, combined with specific DNA target recognition and endonuclease.This technology has wide range of development prospects and high application value in terms of scientific research, agriculture, medical treatment and other fields. In the field of gene therapy, gene editing technology has achieved cross-time success in cancers such as leukemia, genetic disorders such as hemophilia, thalassemia, multiple muscle nutritional disorders and retrovirus associated infectious diseases such as AIDS and other diseases. The preparation work for new experimental methods and animal models combined with gene editing technology is under rapid development and improvement. Laboratories around the world have also applied gene editing technique in prevention of malaria, organ transplantation, biological pharmaceuticals, agricultural breeding improvement, resurrection of extinct species, and other research areas. This paper summarizes the application and development status of gene editing technique in the above fields, and also preliminarily explores the potential application prospect of the technology in the field of traditional Chinese medicine, and discusses the present controversy and thoughts.

To analyze the prognosis and risk factors of acute nonlymphocytic leukemia (ANLL), 94 patients with acute nonlymphocytic leukemia were enrolled in this study, while survival rate and risk factors of prognosis were analyzed. The results indicated that the complete remission (CR) ratio was 51.1%. Overall survival and event-free survival rates of month 6, 12, 18, 24 were 68.6%, 55.8%, 53.8%, 46.4%, 21.3% and 57.9%, 38.6%, 33.3%, 31.6%, 0% respectively. The factors such as age<40 years, WBC<10.0x10(9)/L before chemotherapy, WBC in the period of bone marrow suppression<1.0x10(9)/L, chemotherapy within 1 month after occurrence of leukemia, blood transfusion before chemotherapy of APL had favourable influence on remission and survival rates of ANLL patients. CR1, the time to get CR, length of CR and relapse significantly correlated with prognosis (p<0.05). It is concluded that the individualized therapy concerning the risk factors should be applied to ANLL patients for improving the remission, survival rate and prognosis.
