Aim: To synthesize the ent-kaurene diterpenoid and its derivatives from natural available stevioside.Methods: The crucial pharmacophore of exo-methylene ketone was designed and the carboxyl group at C-4 was modified.The cytotoxic inhibition activities in vitro of target compounds were evaluated against human cancer cells BEL-7402,HO-8910,MCF-7 and HL-60 by a MTT method.Results and Conclusion: The struc-tures of new target compounds were identified by ~1H NMR,FT-IR and EI-MS.The preliminary experimental re-sults showed that some derivatives of ent-kaurene diterpenoid possessed fair inhibitory activity against tumor cell lines compared with that of their parent steviol.

Objective To study the clinical outcomes of 28 pancreatic cancer patients who underwent total pancreaticoduodenectomy.Method The clinical data of 28 patients with pancreatic cancer who underwent total pancreaticoduodenectomy from January 2009 to March 2015 were retrospectively analyzed.Results Among the 28 patients,complications occurred in 11 (39.2％) after the operation.There were 7 patient having Grade Ⅱ,4 Grade] complications.No patient died within 30 days after the operation.Fol low-up of 25 patients showed a median survival of 13.5 months.There were 24 patients with pancreatic ductal adenocarcinoma,and the median survival was 13 months.Conclusions Total pancreaticoduodenectomy could not improve long-term survival but it decreased postoperative complications and improved postoperative quality of life.In selected patients,total pancreaticoduodenectomy could be a rational option.

BACKGROUND:Hidden blood loss is one of most important complications after total knee arthroplasty, but the mechanism and influential factors are not yet clear. OBJECTIVE:To analyze the relative influential factors for hidden blood loss in primary unilateral total knee arthroplasty. METHODS:Data of 235 patients who had undergone primary unilateral total knee arthroplasty from April to September 2014 were retrospectively studied. There were 38 males and 197 females aged from 48 to 82 years old with a mean age of 66 years. The Gross formula was used to calculate the amount of hidden blood loss. The effects of gender, age, height, body weight, body mass index, anesthesia method, administration of tranexamic acid, postoperative anticoagulation method, typeof prosthesis, tourniquet time and pre-operative coagulation function on the postoperative hidden blood loss and total blood loss after total knee arthroplasty were analyzed. RESULTS AND CONCLUSION:(1) Significant differences in hidden blood loss and total blood loss after total knee arthroplasty were detected between male and female patients (P< 0.01). Significant differences in hidden blood loss and total blood loss were found between tranexamic acid and non-tranexamic acid groups (P< 0.05,P< 0.01).(2) Multivariate linear regression analysis showed that preoperative hemoglobin level and heightwere important factors influencing the blood loss after arthroplasty. Hidden blood loss and total blood loss were not correlated with age, body mass index, anesthesia method, postoperative anticoagulation method, type of prosthesis, tourniquet time and preoperative coagulation function. (3) Results indicate that gender and administration of tranexamic acid affect hidden blood loss and total blood loss after total knee arthroplasty. However, age, body mass index, anesthesia method, postoperative anticoagulation method, type of prosthesis, tourniquet time and preoperative coagulation function do not greatly affect hidden blood loss.

Objective To observe the influence of ATP protection after brachial plexus injuries. Methods A total of 80 female Wistar rats,weighting 280～300 g,were randomly divided into ATP and con- trol groups.The right C_5～T_1 nerve roots were transected and then the intraperitoneal injection of 4m[ of ATP or normal saline was given immediately and once daily to the rats,respectively.The rats were sacrificed on postoperative days 14,28 and 42 respectively.The C_5-T_1 segments of the spinal cord were harvested.NT-3 activity was measured by enzymo-histochemistry method.Four weeks and 6 weeks postoperatively,ultrastruc- ture of the denervated skeletal muscles was observed.Results Compared to the control group,the expres- sions of NT-3 was increased in the treated groups with ATP injection (P

Multiple myeloma is a neoplasm of mature and immature plasma cells, it remains an incurable disease using conventional chemotherapy and increasing aggressive approaches. In recent years, due to the better understanding of myeloma biology, genetics and tumor formation, there are lots of new active drugs or combinational chemotherapy regimens having been developed, such as proteasome inhibitors, immunomodulatory agents etc, they are more effective than conventional chemotherapy. This article summarizes the recent advances with the new options for the treatment of multiple myeloma.
