Chinese Traditional and Herbal Drugs 2017;48(22):4804-4818
Sparganium stoloniferum is widely used in traditional Chinese medicines. It has been reported to exhibit therapeutic effects on thrombus, solid tumor, endometriosis and so on. It is usually used to treat endometriosis and chronic atrophic gastritis, while its underlying mechanisms are poorly delineated. According to vast information from literatures in the last decade, the research on origin of medica, chemical compositions and pharmacological actions were summarized, in hopes of offering more clues for further research as well as clinical application of S. stoloniferum.

OBJECTIVE To explore the antitumor effects of combined tanshinoneⅠ(TanⅠ),metformin (Met) and aspirin (Asp) on malignant melanoma in mice and the possible mechanisms. METHODS C57BL/6 mice were injected with 0.1 mL B16F10 cells(2.8×109L-1)to establish the subcutaneous trans-plantation tumor model at the right forelimbs axillary.Then,the mice were divided into 8 groups according to body mass,including model group, TanⅠgroup(20 mg·kg-1,ip),Asp group(210 mg·kg-1,orally in drinking water), Met group (70 mg·kg-1, orally in drinking water), Asp+Met group, TanⅠ+Asp group, TanⅠ+Met group and TanⅠ+Asp+Met group,10 mice in each group.Each mouse drank about 7 mL of water every day for a total of 18 d.The mouse body mass was measured every other day and the tumor diameter was calculated every day. The mice were sacrificed after treatment, the tumor mass was measured and the tumor inhibitory rates were counted. The histopathological changes of the liver and spleen were observed with HE staining. The percentage of lymphocytes in the tumor tissue such as CD8+T,CD4+T and Treg cells was detected by flow cytometry.Inflammatory factors such as interleukin-6 (IL-6),IL-1β and tumor necrosis factor-α (TNF-α) were detected by ELISA. RESULTS The body mass (including tumor mass)of mice in different groups increased during the experiment,but that of TanⅠ+Asp+Met group increased more slower than in model group(P<0.01).At the end of the experiment,no lesions were seen in any liver or spleen tissue by pathological observation,and the number of survivors was 8/10(model group),8/10(TanⅠgroup),7/10(Asp group),7/10(Met group),8/10(TanⅠ+Asp group), 8/10 (TanⅠ+Met group), 7/10 (Asp+Met group) and 5/10 (TanⅠ+Asp+ Met group), respectively. Compared with model group,there were no obvious changes in tumor volume or tumor mass in TanⅠ, Asp and Met groups and other two-two joint groups,but the tumor volume and tumor mass in TanⅠ+Asp+ Met group were significantly decreased (P<0.01, P<0.05), and the tumor inhibitory rate in this group was 46.2%.Compared with the model group,the percentage of CD8+T cells increased(P<0.05) in TanⅠ+Asp+Met group,but there were no significant changes in other groups.The contents of IL-6, IL-1β and TNF-α in tumor tissue of TanⅠ+Met group were much higher than in model group(P<0.01, P<0.05,P<0.05)and the content of IL-6 increased in TanⅠ+Asp+Met group(P<0.01).CONCLUSION Combination of TanⅠ,Asp and Met can effectively inhibit the growth of melanoma in mice,which may be related to the increasing percentage of CD8+T lymphocytes and IL-6 in tumor tissue.However there are possibly some side effects.

The alpha-amylase (EC 3.2.1.1) from the Gram-positive Alicyclobacillus acidocaldarius was one kind of thermoacidophilic enzyme, with optimal temperature and pH of 75 degrees C and 3, respectively. The nucleotide sequence of the gene amy was cloned by PCR. The gene amy was 3901bp long, comprising one open reading frame encoding a polypeptide of 1301 amino acids. The calculated molecular weight of the alpha-amylase AMY was about 140kD. The gene amy was expressed in E. coli BL21 (DE3) and Pichia pastoris respectively, and both of the cloned proteins had bioactivity. The activity of amylase expressed in P. pastoris was further testified by amylase activity staining. The alpha-amylase expressed in P. pastoris had been purified and characterized. The apparent molecular weight of that was about 160kD according to SDS-PAGE. The optimum of pH for the enzyme was pH 3.2 as the native enzyme was; but the optimum of temperature was 65 degrees C and a little lower than that of the native enzyme. Above 50% of relative activity remained after incubation for 30 minutes in 70 degrees C. So the enzyme expressed by P. pastoris was also thermoacidophilic. Moreover some sequence was cloned by PCR, which ranged from + 1174 bp to + 3288 bp in the gene amy, encoding 705 amino acids with the calculated molecular weight of 79kD. The truncated gene amy' was expressed in E. coli BL21 (DE3) induced by 1 mmol/L IPTG, and the expressed enzyme also retained alpha-amylase activity.

OBJECTIVETo evaluate the safety and the clinical value of external use of jiuyi Powder (JP) in treating plasma cell mastitis using partial least-squares discriminant analysis (PLSDA).
METHODSTotally 50 patients with plasma cell mastitis treated by external use of JP were observed and biochemical examinations of blood and urine detected before application, at day 4 after application, at day 1 and 14 after discontinuation. Blood mercury and urinary mercury were detected before application, at day 1, 4, and 7 after application, at day 1 and 14 after discontinuation. Urinary mercury was also detected at 28 after discontinuation and 3 months after discontinuation. The information of wound, days of external application and the total dosage of external application were recorded before application, at day 1, 4, and 7 after application, as well as at day 1 after discontinuation. Then a discriminant model covering potential safety factors was set up by PLSDA after screening safety indices with important effects. The applicability of the model was assessed using area under ROC curve. Potential safety factors were assessed using variable importance in the projection (VIP).
RESULTSUrinary β2-microglobulin (β2-MG), urinary N-acetyl-β-D-glucosaminidase (NAG), 24 h urinary protein, and urinary α1-microglobulin (α1-MG) were greatly affected by external use of JP in treating plasma cell mastitis. The accuracy rate of PLSDA discriminate model was 74. 00%. The sensitivity, specificity, and the area under ROC curve was 0. 7826, 0. 7037, and 0. 8084, respectively. Three factors with greater effect on the potential safety were screened as follows: pre-application volume of the sore cavity, days of external application, and the total dosage of external application.
CONCLUSIONSPLSDA method could be used in analyzing bioinformation of clinical Chinese medicine. Urinary β2-MG and urinary NAG were two main safety monitoring indices. Days of external application and the total dosage of external application were main factors influencing blood mercury and urine mercury. A safety classification simulation model of treating plasma cell mastitis by external therapy of JP was established by the two factors, which could be used to assess the safety of external application of JP to some extent.

OBJECTIVETo investigate the genetic polymorphisms of 11 Y-chromosomal short tandem repeats (Y-STR) loci in 484 male individuals from two minority populations, the Hui and Xibe, of Liaoning province, and to evaluate their forensic application values and genetic relationships with other 15 populations of China.
METHODSEleven Y-STR loci in all samples were amplified with PowerPlex Y System, and the PCR products were analyzed by 310 Genetic Analyzer. Cluster analysis and neighbor-joining tree were applied to show the genetic distance among the populations.
RESULTSIn Hui people, 187 haplotypes were identified, and the overall haplotype diversity value was 0.9990. The gene diversity values (GD) for each locus ranged from 0.4783(DYS437) to 0.9679(DYS385a/b); In Xibe people, 237 haplotypes were identified, and the overall haplotype diversity value was 0.9984. The GD value for each locus ranged from 0.3618(DYS391) to 0.9686(DYS385a/b). Comparing with 15 reference populations, the genetic distance between the Hui and Xibe was the nearest (0.0257), and that between the Hui and Yi was the farthest (0.1046), while the genetic distance between Xibe and Korean was also the farthest (0.0978). The NJ tree was similar to the results of clustering analysis and all the 17 populations were clustered into 3 groups.
CONCLUSIONThe genetic distribution of the 11 Y-STR loci in Liaoning Hui and Xibe ethnic groups showed favorable polymorphisms, therefore are suitable for forensic identification and paternity testing in the local area. The study of haplotype diversity among different populations is useful in understanding their origins, migrations and their relationships.
