This study was aimed to explore the effect of total flavonoids and saponins from Huang-Qi Ge-Gen (HQGG) decoction on blood glucose (BG), serum lipid, interleukin-12 (IL-12) and interleukin-15 (IL-15) of liver in diabetes mellitus (DM) rats, in order to investigate their interactions in regulating DM processes. A total of 66 SD rats were randomly divided into 6 groups, which were the normal group, model group (A1B1), control group, total flavonoids group (A2B1), total saponins group (A1B2), and total flavonoids and saponins group (A2B2), with 11 rats in each group. Except the normal group, other groups were intraperitoneal injected with streptozotocin (STZ). And the experiment was according to 2×2 factorial design experiment scheme. The BG was determined before STZ injection and 7 days after the STZ injection. After 30 days, BG, serum lipid, IL-12 and IL-15 of liver were tested. Related indexes were calculated to the weighted composite score. Main and interactive effect of total flavonoids and saponins were studied according to the factorial design experiment scheme. The results showed that compared with the normal group, all indexes of model group showed statistical differences (P<0.05). Total flavonoids and saponins from HQGG decoction can effectively reduce BG, without any interactions between them. Both the total flavonoids and total saponins can reduce serum cholesterol (CHO), triglyceride (TG), liver IL-12 and IL-15. And there were interactive effects. The single use of herb achieved better effects than the combination. It was concluded that total flavonoids and saponins from HQGG decoction can reduce BG, CHO, TG, and liver IL-12 and IL-15 levels in rats. However, the regulation of total flavonoids and saponins on indexes mentioned above showed no additive effect.

OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.

METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.

RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.

RIG-I-like receptors (RLRs) belong to pattern recognition receptors, which perform significant roles in antiviral responses. RLRs can initiate a cascade of signaling transduction that induces the production of type I interferon and activates the interferon signaling pathway, ultimately resulting in antiviral responses. In the course of evolution, viruses have been constantly counteracting host immune systems to facilitate their own survival and replication, and have developed a set of antagonistic strategies. These mainly comprise elusion, disguise and attack strategies to eliminate the activation of RLRs. In virus-infected cells, RLRs recognize viral RNA and then induce antiviral responses. A better understanding of viral antagonistic strategies against RLRs will provide insights into the development of new antiviral medicines. This mini-review concludes that there are three main antagonistic strategies by which RNA viruses can counteract the activation of the RLRs pathway. It aims to provide references and insights for similar studies on viral antagonism in an array of RNA viruses.

The optimum medium for Lactobacillus M7 was systematically studied with SAS system. Firstly, the prime factors affecting lactic acid yield were selected by means of Plackett-Burman design; secondly, the pnme facias were optimized by response rurface analysis. Under the optimum level determined, the yield is increased by 15%.

OBJECTIVETo investigate the pathogenesis of globozoospermia, fertilization ability of round-headed sperm, and the application value of assisted oocyte activation in intracytoplasmic sperm injection (ICSI) for the wives of glohozoospermia men.

METHODSWe collected oocytes from the wives of 2 globozoospermia patients and randomly divided them into two groups after ICSI to receive calcium ionophore A23187-activation and conventional treatment, respectively. We reviewed the relevant literature published at home and abroad, and discussed the etiology of globozoospermia, fertilization ability of round-headed sperm, and treatment options for this disease.

RESULTSQuality embryos were obtained in the A23187-activation group while no fertilized oocytes, oocyte cleavage, quality embryos, or blastular formation were found in the conventional treatment group. Both women achieved pregnancy and gave birth to healthy neonates after transfer of the quality embryos from the A23187-activation group.

CONCLUSIONCalcium ionophore A23187 can be applied to ICSI for the wives of globozoospermia men and bring about desirable clinical outcomes. Meanwhile, attention should be paid to its safety.
