To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.

Objective To evaluate the efficacy and safety of the unilateral and bilateral drainage in hilar malignant biliary obstruction with a meta?analysis of relevant studies. Methods A systematic electronic search with keywords “ biliary stent”, “hilar tumor” and “malignant biliary obstruction” was independently performed by two reviewers in major electronic databases of Pubmed, EMBASE, Cochrane Library and Web of Science. A meta?analysis was conducted using Revman 5?? 1 software. Results Six studies were included with a total number of 558 patients, of whom 307 patients underwent unilateral biliary drainage and 251 pa?tients bilateral drainage. There was no significant difference in early complications ( OR = 1?? 03,95% CI:0?? 58?1?? 81,P = 0?? 93), later complications (OR = 0?? 98,95%CI:0?? 46?2?? 07,P = 0?? 95), operation success rate (OR= 1?? 42,95%CI:0?? 76?2?? 66,P = 0?? 28),drainage efficacy or median survival time between the two groups. Compared with unilateral biliary drainage, bilateral biliary drainage had a longer time of stent patency (MD = - 29?? 12,95% CI:- 38?? 55?- 19?? 70,P< 0?? 001). Conclusion Both unilateral and bilateral biliary drainage are safe and effective for hilar malignant biliary obstruction, but more high quality clinical researches are needed.

OBJECTIVETo explore the effect of moxibustion at Sanyinjiao (SP 6) on normal process of childbirth and safety of mothers and infants.

METHODSOne hundred and seventy-four cases of singleton primiparas, fetal head position were selected as the subjects and divided into three groups by single-blind randomized method: an acupoint group (n = 59), a non-acupoint group (n = 57) and a blank group (n = 58). When the cervix was dilated by 2 to 3 cm, DAJ-23 type multi-function moxibustion apparatus was used at Sanyinjiao (SP 6) in acupoint group, and at non-acupoint spot (the midpoint from the radial arterial pulse throbbing place on the radial side of the transverse crease of the wrist to the radial end of biceps tendon of the elbow) in non-acupoint group, 30 min for each one. The conventional labor care was adopted in blank group. The differences were observed in the first active stage, the second stage and the third stage of the labor as well as the safety of mothers and infants among three groups.

RESULTSThe durations of the first active stage of labor [(123.05 +/- 96.401) min] and the second stage [(37.407 +/- 22.390) min] in acupoint group were shorter than those [(171.40 +/- 94.339) min, (49.517 +/- 25.373) min] in non-acupoint group, as well as those [(178.79 +/- 97.231) min, (53.684 +/- 20.087) min] in blank group separately (all P < 0.05). It was discovered that the progressions of the first active stage and the second stage of labor were accelerated in acupoint group, and there was no statistically significant difference in the third stage of labor among the three groups (all P > 0.05). Bleeding amount after childbirth in acupoint group was less than those in non-acupoint group and blank group (both P < 0.05), and Apgar scores of newborns in acupoint group and non-acupoint group were higher than that in blank group (both P < 0.05).

CONCLUSIONMoxibustion at Sanyinjiao (SP 6) can shorten the process of childbirth, reduce postpartum bleeding and has no harmful impact on mothers and infants.

OBJECTIVETo explore the lipid peroxidation and the testicular morphological change induced by decabrominated diphenyl ether (BDE-209) in male BALB/c mice.

METHODSTwenty one male BALB/c mice were randomly divided into three groups: the high exposure group (500 mg/kg BDE-209), the low exposure group (200 mg/kg BDE-20) and control group (normal saline). The mice were exposed by gavage one time a day for 6 weeks, then were sacrificed. Body weight, testis weight, malonyldialdehyde (MDA), total superoxide dismutase (T-SOD) and glutathione (GSH) in testis were examined. The morphological alteration of testis was observed. TUNEL assay was used to detect the apoptosis in testicular cells.

RESULTSBody weight and testis weight in high and low exposure groups were (21.6140 +/- 2.3550) g, (20.8000 +/- 1.7630) g and (0.1859 +/- 0.0349) g, (0.1718 +/- 0.0266) g, respectively, which were significantly lower than those (27.7570 +/- 1.2880) g and (0.2302 +/- 0.0335) g in the control group (P < 0.05); the testis coefficient in high exposure group was (0.8640% +/- 0.1706%), which was significantly higher than that (0.8329 +/- 0.1386%) in the control group (P < 0.05). The GSH level and SOD activities of testis in 2 BDE-209 groups were 0.044 +/- 0.006, 0.039 +/- 0.005 nmol/mg prot, and 0.735 +/- 0.179, 0.907 +/- 0.198 U/mg prot, respectively, which were significantly lower than those (0.052 +/- 0.067) mol/mg and (1.161 +/- 0.188) U/mg in the control group (P < 0.05). The levels of MDA in 2 BDE-209 groups were (2.365 +/- 0.339) and (1.752 +/- 0.366) nmol/mg prot, which were significantly higher than that (1.173 +/- 0.232 nmol/mg prot) in control group (P < 0.05). there were significant differences of SOD and MDA levels between high exposure group and low exposure group (P < 0.05). Histological examination showed that the number of spermatogenic cells and layer were decreased significantly in 2 exposure groups as compared with control group. TUNEL assay showed that apoptosis cells appeared in 2 exposure groups.

CONCLUSIONBDE-209 changed lipid peroxidation in male BALB/c mice testis and caused toxic effects on the testis.
