Background and purpose:Despite the high remission rate in patients with multiple myeloma (MM) after the standard regimen, but often relapsed and resistant. It has been shown that modulation of cAMP can induce cell cycle arrest and apoptosis in a variety of tumor cells, which has become an interesting approach to cancer therapy. This study aimed to investigate possible effects of cyclic adenosine monophosphate (cAMP) analogue 8-(4-chlorophenylthio) adenosine 3’, 5’-cyclic monophosphate (8-CPT-cAMP) on multiple myeloma cells, provide direction to develop new drugs for the treatment of MM. Methods:The myeloma cell line U266 cells were treated with 8-CPT-cAMP of different concentrations. The proliferation of U266 cells was evaluated through cell counting kit (CCK-8) assay, lfow cytometry was used to analyze the changes of cell were distribution, apoptosis rate as well as mitochondrial transmem-brane potential (ΔΨm) in U266 cells before and after the treatment. Meanwhile, real-time quantitative polymerase chain reaction (RT-PCR) and Western blot assay were used to detect expression levels of apoptosis regulators including caspase-8, caspase-9, Bcl-2 and Bax genes in U266 cells before and after the treatment. Results:The U266 cells were treated 5 days with 8-CPT-cAMP of different concentration, it was shown that 8-CPT-cAMP could signiifcantly inhibit cell growth of U266 cells in a concentration and time dependent manner, the IC50 of 8-CPT-cAMP was reduced obvious prolonged reaction time, and reached to 58.52μmol/L in the iffth day. The cell cycle of U266 cells was stopped in G0/G1 stage as the progress of concentration. It was showed statistical signiifcant difference associated with the cellular proliferation inhibition rate and apoptosis rate in different concentration and control (P<0.05). Meanwhile, 8-CPT-cAMP could induce mitochondrial transmembrane potential collapse in U266 cells. Compared with control groups, the levels of Bcl-2 mRNA transcripts and protein in U266 cells were reduced in 8-CPT-cAMP treated groups (P<0.05), while the levels of caspase-9, Bax mRNA transcription and the expression of Bax protein were increased in treatment groups, but the caspase-8 mRNA had no statistical signiifcant difference with controls. Conclusion:8-CPT-cAMP can inhibit the proliferation and promote apoptosis of myeloma cells, which might be mediated by caspase via mitochondrial pathway.

Objective To assess the feasibility and safety of transradial puncture route for digital subtraction angiography (DSA)in young patients with ischemic cerebrovascular disease. Methods One hundred young patients with cerebrovascular disease who underwent whole brain angiography at the Department of Neurology,the 81 st Hospital of PLA were enrolled. They were divided into either a radial group (n =50)or a femoral group (n = 50)using a computer random number method. The time of puncture,success rate of puncture,success rate of selective angiography,exposure time,and incidence of complications were compared and analyzed. Results (1)The puncture time of the radial group was significantly longer than that of the femoral group,they were 3. 00 ± 0. 50 min and 1. 50 ± 0. 25 min respectively. There was significant difference (t = 18. 97,P < 0. 05). There were no significant differences in the success rate of puncture (98% vs. 100%),success rate of selective angiography (100% vs. 100%),and exposure time (5. 3 ± 2. 2 vs. 4. 8 ± 1. 7 min)between the two groups (all P > 0. 05). (2)The incidence of complications of the radial group (4%,n = 2)was significantly 1ower than that of the femoral group (18%,n = 9 ). There was significant difference between the two groups (χ2 = 5. 01,P < 0. 05 ). Conclusion Transradial route puncture for whole brain DSA in young patients with cerebrovascular disease is safely and feasible.

Objective:To observe the effects of salidroside on the expression of substance P (SP)and neurokinin-1 receptor (NK-1R)of bone marrow cells(BMCs)in bone marrow(BM)depressed anemia mice,and to explore its roles for hematopoietic regulation.Methods:Automatic blood cell analysator was used to detected the changes of peripheral blood cells in each group ,immuno-histochemistry and reverse transcription-polymerase chain reaction ( RT-PCR) were used to analyze the expressions of SP and its receptor NK-1R of BMCs in each group respectively.Results: Peripheral blood testing results showed that the number of white blood cells (WBC),red blood cells(RBC)and hemoglobin(HB)of model group were significantly decreased when compared with control group.Compared with model group ,low-dose,middle-dose and high-dose salidroside obviously elevated the number of white blood cells ,and middle-dose salidroside obviously elevated the number of platelets.Immunohistochemistry studies showed that the expression of SP and its receptor NK-1R of BMCs was found in each group.Compared with control group , the expression of SP of BMCs was decreased obviously in model group(P<0.05),and the expression of NK-1R of BMCs was decreased slightly in model group (P>0.05),and the expression of SP and its receptor NK-1R of BMCs was increased significantly in low-dose,middle-dose and high-dose salidroside groups (P<0.05).RT-PCR data showed that the expression of SP mRNA of BMCs was increased obviously in model group ,low-dose,middle-dose and high-dose salidroside groups when compared with control group (P<0.05).The expression of NK-1R mRNA of BMCs was un-detected in control group and model group.The expression level of NK-1R mRNA of BMCs was elevated gradually with the increase of salidroside dosage in low-dose,middle-dose and high-dose salidroside groups.Conclusion: The mRNA and protein expressions of SP and its receptor NK-1R of BMCs were up-regulated significantly by salidroside in dose-dependent manner.These data suggest that salidroside could participate in the recovery of hematopoietic function of BM depressed anemia mice by increasing the expression of SP and its receptor NK-1R of BMCs.

For a long time, limited by the factors such as laparoscopic technology, and limited medical resources , the residents accepting standardized training are lack of mastery of the technology . Meanwhile, it is the key to the training of personnel training and reserve in the field for residents to contact the laparoscope as soon as possible and carry out scientific and effective training. Therefore, based on the traditional method, we have developed a new type of laparoscopic teaching system for the standardized training residents and increased and integrated the LAP GAME R operations training system and the real-time multimedia teaching platform. The preliminary practice effect is good.

The principal investigator responsibility system has been progressively under implementation at some of the domestic medical universities. However, since there are big differences between military medical universities and civilian ones in terms of organizational structures, tasks to be committed, functions and personnel systems, military medical universities have to consider own characteristics and well handle the following four pairs of relations in the process of implementing principal investigator responsibility system: the relation between the subject groups and the teaching and research sections, the relation between the subject research and the discipline construction, the relation between the subject research and the personnel training, and the relation between the collective assessment and the individual assessment in the process of performance assessment.
