Effect of ginsenoside total saponin (GTS) on the regulation of P450 of livers of rats after γ-ray irradiation was studied. Rats were irradiated by the ⁶⁰Coγ-ray for one-time dose of 5.5 Gy, dose rate of 117.1-119.2 cGy. The cocktail probe, qPCR and Western blot were used to detect expression of enzymatic activites, mRNA and protein of rats. Contrasted with blank group, expression of CYP1A2, 2B1, 2E1, 3A4 of irradiation group showed a up-regulated (P < 0.05). Contrasted with irradiation group, exprression of CYP1A2, 2B1, 2E1, 3A4 of GTS group showed a downward trend. GTS had negative agonistic action against expression of P450 of rats by irradiatied.

Five H9N2 avian influenza virus strains were isolated from the environmental samples in live poultry market in Qinghai Lake region from July to September, 2012. To evaluate the phylogenetic characteristics of these H9N2 isolates, the eight gene segments were amplified by RT-PCR and sequenced. The phylogenetic and molecular characteristics of the five strains were analyzed. The results showed that the HA genes of five strains shared 93. 2%-99. 1% nucleotide identities with each other, and the NA genes shared 94. 5%-99. 8% nucleotide identities. The HA cleavage site sequence of the A/environment/qinghai/ 017/2012 isolate was PSKSSRGLF, and the HA cleavage site sequences of the other four strains were all PSRSSRGLF. The HA receptor-binding site had the Q226L mutation. The M1 gene segment had the N30D and T215A mutations. The phylogenetic analysis showed that the five strains were similar to the virus A/chicken/Hunan/5260/2005 (H9N2) isolated in Hunan Province, China and were reassortant genotype viruses; the HA, NA, and NS genes belonged to the Y280-like lineage; the MP gene belonged to the G1-like lineage; the NP, PB1, PB2, and PA genes belonged to the F98-like lineage.

In recent years, with the change in life style, social environment, and national childbearing policy, the proportion of high-risk pregnant women has increased significantly, triggering the spectrum of obstetric diseases to constantly change, which has brought new challenges to the diagnosis and treatment of obstetrics. Traditional Chinese medicine (TCM) has been proved effective in dealing with a variety of obstetric diseases, and various treatment methods are available, which can serve as alternative means for solving refractory obstetric diseases. However, most obstetric clinicians are currently less aware of the therapeutic effects of TCM, which has significantly hindered its participation in clinical treatment. Therefore, the China Association of Chinese Medicine (CACM) organized the outstanding young obstetricians of TCM and western medicine to discuss 15 obstetric diseases responding specifically to TCM or integrated TCM and western medicine, including hyperemesis gravidarum, threatened abortion, ectopic gestation, cough during pregnancy, pregnancy-induced hypertension syndrome, maternal-fetal ABO incompatibility, postpartum hypogalactia, residual pregnancy tissue in uterine cavity, puerperal infection, pantalgia after childbirth, hematoma/undesirable healing after caesarean section, postpartum urinary retention, ileus after cesarean section, pelvic floor dysfunction, and postnatal depression. The suggestions for their treatment with TCM or integrated TCM and western medicine were also proposed, aiming to provide patients with effective and personalized treatments in clinical practice and improve the diagnosis and treatment effects of obstetric diseases, thus benefiting the public. At the same time, more obstetrical clinicians are expected to understand the therapeutic effects and advantages of TCM and draw on the strengths of both TCM and western, thereby promoting the establishment of an obstetric diagnosis and treatment system with Chinese characteristics.
