[Objective] To compare and identify the different cultivated varieties of Amormun villosum for providing scientific evidence for the selection, breeding, standardization and industrialization. [Methods] Source appraisal, character identification and scanning electron microscope technique were applied to observe and compare the appearance of the original plant, the properties of the medicinal material and the outside characteristics of pollen of Amomum villosum in Yangchun, Guangdong province. [Results] The two cultivated varieties of Amomum villosum in this area, long-fruit and round-fruit types, are quite different in the appearance and the characteristics of pollen. [Conclusion] It is suggested that long-fruit Amomum villosum and round-fruit Amomum villosum should be the selected varieties for breeding.

【Objective】To devise the optimal method and the optimal water content for the storage of seeds of Aquilaria sinensis(Lour.) Gilg..【Methods】The seeds of Aquilaria sinensis(Lour.) Gilg.were stored in plastic bag,drying apparatus,wet sand and dry sand separately.And then the germination capacity of the seeds with different water content was detected at 4℃ and room temperature(30℃) in different time.【Results】The germination capacity of Aquilaria sinensis(Lour.) Gilg.decreased with the prolongation of storage time and with the decrease of water content.The seeds with water content being 9.34% and 7.35% had a higher germination capacity when stored at 4℃ for 35 days than that stored at room temperature.The fresh seeds stored in wet sand sprouted and the seeds stored in drying apparatus and dry sand had lower germination capacity and went mouldy.【Conclusion】Low temperature and moderate water content are benificial to the storage of the seeds of Aquilaria sinensis(Lour.) Gilg..

【Objective】To explore the long-term storage method for the seeds of Aquilaria sinensis(Lour.)Gilg..【Methods】The seeds of Aquilaria sinensis(Lour.)Gilg.with different water contents were preserved with liquid nitrogen for 55 days.And then the seeds were taken out to detect their germination capacity.The effect of cryopreservation methods on the germination capacity was also observed.【Results】The seeds with water content being 16.30% lost their germination capacity completely,the seeds with water content being 13.02% and 9.34% had a lower germination capacity,and the seeds with water content being 7.35% had a higher germination capacity.Quickly-frozen seeds had a higher germination capacity than the slowly-frozen seeds.【Conclusion】Cryopreservation with liquid nitrogen is suitable for the long-term preservation of the seeds of Aquilaria sinensis (Lour.)Gilg.with water content being 7.35%.

Pancreas and islet transplantation is the only treatment that can cure type 1 diabetes mellitus. Less invasive and more targeted surgical and immunosuppressive regimens make islet transplantation a more attractive treatment for type 1 diabetes. Current methods of islet isolation and purification cause hypoxic stress to which β cells are extremely vulnerable. Transplanted islets need to re-establish their vascular system in order to obtain sufficient oxygen and nutrient supply for stable engraftment. However, this process takes at least 7- 14 days to complete. Massive (＞50%) β cells are dead before revascularization due to hypoxia, especially the core of the islets. Therefore, the obvious critical problem is the circulatory deficit to which the islets are susceptible in the immediate post-transplant period.In the current study, we reviewed various hypoxic-related insults to islets before complete engraftment, and feasible strategies to reduce hypoxic-induced apoptosis based on our experimental experiences together with that of others and investigated the possibility of revascularization in islet transplantation.

Objective To study the effect of inosine monophosphate dehydrogenase inhibitor (IMPDHI) on chemotaxis, migration and endocytosis of human peripheral myeloid dendritic cells (MDCs). Methods Freshly isolated peripheral blood mononuclear cells(PBMC)collected from healthy volunteers (N=15) and the study group were treated with IMPDHI. CC chemokine receptors on MDCs were analyzed by flow cytometry. The study group, control group and different chemokines were added via trans-well approach for different chemokines, stained by Lin-1/CD11c/HLA-DR and counted by flow cytometry. The migration index was calculated as a percentage of MDC migrated in response to the tested chemokine. After isolation of blood dendritic cell antigen-1+ (BDCA-1+ ), mannose receptor-mediated endocytosis was measured as the cellular uptake of FITC-dextran by the flow cytometry. Results (1) Compared to the control group, the expression of CCR1 in the study group was up-regulated significantly(17.02±3.23～30.63±9.13, P＜0.05) and the expressions of CCR3(10.26±2.25～5.81±0.97 P＜0.05) and CCR7 (9.56± 1.84～5.18±0.60 P＜0.05)were downregulated significantly. MDCs in the study group showed enhanced migratory response to inflammatory chemokine CCL2, CCL3, CCL4, CCL7 and CXCL12 (P＜0.05). (2)The endocytosis capacity in the study group was significantly higher than that in control group (P ＜0.05). Conclusion IMPDHI enhances the endocytotic capacity of MDCs and impairs the migratory response of peripheral MDCs to lymphocytic tissue by up-regulating the expression of chemokine receptor in MDCs and enhancing migratory response to inflammatory chemokines.

Objective To evaluate the efficacy of PAD regimen (bortezomib, doxorubicin, dexamethasone) and VAD-like T regimen (vincristine, doxorubicin/doxorubicin derivatives, dexamethasone combined with thalidomide) in the treatment of patients with newly diagnosed multiple myeloma (MM). Methods The efficacy of 54 patients with MM who received VAD like-T regimen and 72 patients with MM who were treated with PAD regimen, including complete remission (CR) rate, very good partial remission (VGPR) rate, overall response rate (ORR), overall survival (OS), progression-free survival (PFS) and adverse events, were retrospectively analyzed. Results The CR rate of PAD group was higher than that of VAD-like T group [31.5 % (23/72) vs. 9.3 % (5/54), χ2=0.30, P=0.002]. The VGPR rate and ORR of PAD group were not statistically higher than those of VAD-like T group [16.7 % (12/72) vs. 16.6 % (9/54), P=0.180; 82.2 %(65/72) vs. 81.5 % (44/54), P=0.190, respectively]. Median PFS of PAD group was significant longer than that of VAD-like T group [(38.2±2.2) months vs. (28.0±7.6) months, P=0.017]. The 3- and 5-year OS rates of PAD group were higher than those of VAD-like T group, but there were no significant differences between two groups (P>0.05). In terms of the adverse events, the incidence of peripheral neuropathy in PAD group was significantly higher than that of VAD-like T group [31.5 % (23/72) vs. 14.5 % (8/54), P=0.03]. Conclusions Compared with PAD protocol, the CR and median PFS of VAD-like T regimen are poor, however, VGPR,ORR, PFS and 5-year OS are similar between the two groups, and VAD-like T regimen is safer with low incidence of peripheral neuropathy. VAD-like T regimen as the first-line treatment is effective and well-tolerated, especially for newly diagnosed MM patients not suitable for transplantation and bortezomib.
