The development and utilization of herbal medicinal resourses in south China were reviewed from the following aspects: (1) resources investigation; (2) introduction of South China herbal medicine (SCHM) to North China; (3) culture technology of green herbal medicine; (4) building of the base of good agriculture practice; (5) species study and quality evaluation of SCHM, and (6) product development of SCHM. It is concluded that the research on development and utilization of SCHM contributes a lot to reducing SCHM import, saving foreign exchange and ensuring the safety, effect, output stability and quality control in the production of medicinal material.

[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 study the chemical constituents of Lignum Aquilariae Resinatum.MethodsThe compounds were isolated and purified by silica chromatography and their structures were identified on the basis of physicochemical constant and spectral analysis.Results The compounds were determined as 6-hydroxy-2-[2-(3'-methoxy-4'-hydroxy phenylethyl)] chromone(Ⅰ)and a triterpene,hederagenin(Ⅱ).Conclusion Compound I is a new compound and compound Ⅱ is found in this plant for the first time.

【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%.

Objective To systematically evaluate the efficacy and safety of injected hemocoagulase Agkistrodon for intraoperative bleeding.Methods We electronically searched several Chinese database till May 2014 to identify randomized controlled trials (RCTs) about injected hemocoagulase Agkistrodon for operative hemorrhage.The methodological quality of included RCTs was assessed,and the data were extracted by two reviewers independently according to the Cochrane Handbook.The homogeneous RCTs were pooled using RevMan software (Version 5.1.0).Results 2 358 articles were searched initially,and 12 RCTs involving 1 031 patients met the inclusion criteria.The results of Meta-analyses showed that:in the study groups,the average haemostatic time of the wound is shorter [OR =-40.29,95％ CI(-71.13,-9.44),P =0.01],the hemorrhagic volume of the wound [OR =-1.38,95％ CI(-1.90,-0.87),P ＜ 0.000 01],hemorrhagic volume per unit area of the wound [OR =-0.05,95％ CI(-0.06,-0.03),P ＜ 0.00001],introperative hemorrhagic volume and drainage volume on POD1 [OR =-18.52,95％ CI (-25.50,-11.53),P ＜ 0.000 01] are lower than the placebo groups.In all studies,no difference was found in the variation of hemostatic function,liver and renal function and drug-induced adverse events.Conclusions The injection of hemocoagulase Agkistrodon can significantly reduce the average haemostatic time of the wound,the hemorrhagic volume of the wound,overall introperative hemorrhagic volume and drainage volume on POD1,and does not affect the hemostatic function,liver and renal function and not increase the incidence of adverse effects or postoperative complications.

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 observe the clinical effect of percutaneous transluminal angioplasty (PTA)combined with autologous peripheral blood stem cells(PBSC)transplantation in the treatment of lower extremity ischemic disorders.Methods Fourty-two cases of lower extremity ischemic disorders in the treatment group were treated with PTA and autologous peripheral blood stem cells injection and 40 cases in control group were treated with PTA exclusively.Results All the procedures were successful.In treatment group,ABI improved from 0.32 ±0.11 to(at the 3rd month)and 0.49 ±0.13(at the 6th month)(t=-6.765,-6.040,P＜0.05)while TcPO_2 improved from(26.1 ± 2.3)mm Hg to(32.7 ±4.2)mm Hg(at the 3rd month)and(34.5 ±2.7)mm Hg(at the 6th month)(t=-8.901,-14.250,P＜0.05).In control group,ABI improved from 0.30 ±0.12 to 0.47 ±0.15 and 0.47 ±0.130=-5.631,-5.873,P＜0.05)while TcPO_2 increased from(25.9 ±2.4)mm Hg to(28.9 ±2.9)mm Hg(at the 3rd month)and(28.9 ± 2.1)mm Hg(at the 6th month)(t=-5.090,-5.389,P＜0.05).There was significant difference in TcPO_2 on follow-up between the two groups after the treatment(P＜0.05).Conclusion Autologous PBSC transplantation in combination of PTA was effective for the treatment of lower extremity ischemic disorders.PBSC injection helps to increase TcPO_2.
