Having referred the Chinese academic publications on TCM during the last decade ,we summarized the researches in Angelica Decoction (AD), which included immunoregulatory, circulatory system, the basis of decoction composition, anti-oxidation, liver injury and compaibility. AD can improve the immunity action, meliorate abnormal circulation, and also has the effects of anti-oxidation and protection of liver injury. Futher study on AD should be focused on its mechanism and material basis in the future.

Objective To prospectively investigate the optimal setting for sentinel lymph node biopsy (SLNB) in patients with breast cancer by comparing the effects of different preparation methods and injection sites of 99Tcm-SC in sentinel lymph node (SLN) mapping and detection.Methods Two batches of 99Tcm-SC were prepared by boiling for 3 min (radiotracer 1) and 5 min (radiotracer 2),respectively.Radioactive chemical purity (RCP) and size of colloid particles were measured at 10 min,1 h,2 h and 4 h after the preparation.One hundred and forty-seven patients with breast cancer were involved and randomly divided into 3 groups.Group A consisted of 40 patients with periareolar injection of radiotracer 1,group B of 40 patients with periareolar injection of radiotracer 2,and group C of 67 patients with peritumoral injection of radiotracer 2.Lymphatic mapping was performed for all patients using SPECT/CT preoperatively and blue dye was subdermally injected over the tumor.The detection rate of the axillary and internal mammary SLN was recorded.One-way analysis of variance,independent two-sample t and x2 tests were used to analyze the data.Results There was no significant difference of RCP between the two radiotracers at 10 min,1 h,2 h and 4 h after preparation (t =-0.267,-0.794,0.826 and-0.977,all P>0.05).Compared with radiotracer 1,the percentage of particles smaller than 100 nm in radiotracer 2 reduced significantly ((73.72±2.36) % vs (65.25±3.56)%,t=6.436,P<0.05) and the mean effective particle size was significantly larger ((45.27±6.42) nm vs (75.59t7.04) nm,t=7.315,P<0.05).In groups A,B and C,the detection rate of the internal mammary SLN was 70.0% (28/40),47.5% (19/40) and 17.9% (12/67),respectively,with significant difference (x2=29.525,P<0.05).In groups A,B and C,the detection rate of the axillary SLN was 100% (40/40),95.0% (38/40) and 97.0% (65/67),respectively,without significant difference (x2 =2.686,P> 0.05).Conclusion For SLNB of patients with breast cancer,the axillary and internal mammary SLN could be better detected by SPECT/CT lymphatic mapping using radiotracer prepared with a shorter boiling time,via periareolar injection,and combined with subdermal injection of blue dye.

[Objective] To optimize the conditions of the extracting process of Hujin Granules. [Methods] The orthogonal design was applied. With the total emodin and the total anthraquinone (TA) content as the parameters for the alcohol-extraction, the concentration of alcohol, the volume of solvent and the extracting time were used for optimization of alcohol-extraction. With the total polysaccharide (TP) as the parameters for water-extraction, the soaking time, the volume of water and the extracting time were used for optimization of water-extraction. [Results] The optimum conditions of alcohol-extraction were: extracting with 70% alcohol 245 mL for 2 hours and extracting twice. The optimum conditions of water-extraction were: extracting with 80 mL water (not for soaking) for 1.5 hours, extracting 3 times. [Conclusion] The results indicate that the extracting process is rational and feasible, and can provide evidence for the extracting process of Hujin Granules.

Objective To evaluate the clinical value of 99Tcm-Tilmanocept(TMC) SPECT/CT for the detection of SLN by comparing with 99Tcm-sulfur colloid(SC) SPECT/CT. Methods From March 2016 to September 2016, a total of 160 patients (age range: 30-70 years), selected from Breast Surgery Department of Shandong Cancer Hospital, underwent SPECT/CT and planar imaging with either 99Tcm-TMC (TMC group, n=76) or 99Tcm-SC (SC group, n=84). The results of SLN SPECT/CT and planar imaging were compared. The positive rate of SLN in SPECT/CT was compared with operative results. One-way analysis of variance, χ2 test, and two-sample t test were used for data analysis. Results The radiochemical purity of 99Tcm-TMC (≥92%) had no significant difference in 4 h(F=0.720, P>0.05). In TMC group, the average number of SLN detected by SPECT/CT imaging was higher than that by planar imaging (1.34±0.64 vs 0.96±034; t=4556, P<005). In SC group, the average number of SLN detected by SPECT/CT imaging was also higher than that by planar imaging (2.57±0.99 vs 1.56±0.87; t=7.010, P<0.05). The positive rates of SLN in TMC and SC groups were 94.7%(72/76)and 96.4%(81/84), showing no significant difference (χ2=0273, P>0.05). The average number of SLN detected by 99Tcm-TMC imaging was significantly lower than that detected by 99Tcm-SC (t=9.115, P<0.05). The intraoperative detection rates of SLN were 100% (76/76 and 84/84) in both groups. The average number of SLN detected during operation in TMC group was significantly lower than that in SC group (1.89±0.86 vs 3.05±1.29; t=6.642, P<0.01). In TMC group, the average number of SLN detected during operation was significantly higher than that detected by SPECT/CT(1.89±086 vs 1.34±0.64; t=4.492, P<0.05). In SC group, the average number of SLN detected during operation was significantly higher than that detected by SPECT/CT(3.05±1.29 vs 2.57±0.99; t=2.740, P<005). Conclusions SPECT/CT is superior to planar imaging for the detection and localization of SLN. 99Tcm-TMC is suitable for SLN imaging and intraoperative detection.

Objective To study the effect of Aloe polysaccharides (AP) on the thymocytic apoptosis and cell cycle in ? - ray irradiated mice. Methods Single- cell thymocytes suspension was sampled at different time points to observe the thymocytic apoptosis and cell cycle by flow cytometry. DNA ladders were tested by 1.8 % agarose gel electrophoresis. Transmission electron microscopy was used to examine the ultrastructure of thymocytes. Results Pre- treating with AP (50 mg/kg,ip) 30 min before irradiation could significantly decrease the percentages of apoptotic thymocytes in? - ray irradiated mice 4 h, 8 h and 12 h after irradiation, increase the percentage of thymocytes at G0/G1 phase and reduce the percentage of thymocytes at G2/M phase. It could also lessen the DNA ladders and reduce the number of apoptotic bodies. Conclusion The protective effects of AP on the thymocytes in ? - ray irradiated mice is related with the alleviation of the disorder of cell cycle and the inhibition of the apoptosis of thymocytes.
