To investigate the clinical effect of tonifying the kidney and promoting blood circulation to promote oocyte decoction in the treatment of anovulatory infertility caused by polycystic ovary syndrome. Sixty cases were selected from the out-patient department of Xiyuan hospital of China academy of Chinese medical sciences and the Chinese academy of traditional Chinese medicine, Chinese medicine out-patient department. Sixty patients with PCOS patients were randomly divided into the treatment group and the control group, with 30 cases and 30 cases respectively. The treatment group was given decoction of the reinforcing kidney, activating blood circulation and ovarian stimulation compound recipe. The control group was treated with clomiphene. Through the treatment of 1-2 courses, in the treatment group the pregnancy rate was 56.67%, the ovulation rate 61%; in control group of clomiphene citrate ovulation ratepregnancy rate was 30% , 72.84% of ovulation rate. The difference was significant between two groups (P < 0.05), the pregnancy rate in the treatment group was higher than the control group. The treatment group has regulatory effect on FSH, LH and their ratio, and increase E2 level, decrease T, PRL, INS and other hormone levels, contributing to the mature development of the follicles and endometrium growth, increase the ovulation rate and pregnancy rate. The control group on FSH, E2 increased, LH, T, PRL and INS showed no obvious effect.

BACKGROUND:The effect of body mass index (BMI) on the outcomes ofin vitrofertilization (IVF) is controversial. Some scholars suggested that the higher BMI, the lower rate of pregnancy, and the higher rate of abortion. However, some others got the different results. To data, the effects of BMI on the pregnancy outcomes in females at different ages are rarely reported.
OBJECTIVE:To explore the effect of BMI on the pregnancy outcomes of IVF for infertile women atdifferent ages.
METHODS:A total of 902 cycles undergoing IVF were divided into two groups according to the age:≤ or> 35 years old groups. The patients in each group were then divided into four subgroups according to BMI: low weight, normal weight, excess weight, and obesity subgroups, respectively.
RESULTS AND CONCLUSION: With increasing BMI, the average dosage of gonadotropins was increased gradualy in two both of age groups (P < 0.05). In the≤ 35 years old, the levels of estrogens on the day of injecting human chorionic gonadotropin was significantly lower in obesity group than the other subgroups (P < 0.05); the rates of empty folicle in excess weight and obesity subgroups were significantly higher than that in normal weight subgroup (P < 0.008 23). The fertilization rate and clinical pregnancy rate of in obesity subgroup were significantly lower than those in the other subgroups (P < 0.05). In the > 35 years old group, the empty folicle rate in obesity subgroup was significantly higher than that in normal weight subgroup (P < 0.008 23). Fertilization rate in excess weight and obesity subgroups was significantly lower than that in the normal weight subgroup (P< 0.008 23). There were no significant differences in cleavage rate, cycle cancelation rate, implantation rate, biochemical pregnancy rate and abortion rate between four subgroups (P> 0.05). These findings suggest that in the females at the younger age, BMI not only affects the quality of folicles and fertilization rate; but with increasing BMI, clinical pregnancy rate is decreased obviously. However in the females at the older age, BMI only affects the folicular quality, embryo quality and fertilization rates; there are no significant differences in the outcomes of pregnancy in the four subgroups. BMI have effects on pregnancy outcomes of IVF, and the effects are much greater in the younger female group.

OBJECTIVETo discuss the mechanism of gambogenic acid (GNA) in inducing the apoptosis of melanoma B16 cells.

METHODThe inhibitory effect of GNA on the proliferation of B16 cells was measured by the methyl thiazolyl tetrazolium (MTT) assay. The effect of GNA on B16 cells was detected by the Hoechst 33258 staining. The transmission electron microscopy was used to observe the ultra-structure changes of B16 cells. The changes in PI3K, p-PI3K, Akt, p-Akt, p-mTOR, PTEN proteins were detected by the Western blotting to discuss the molecular mechanism of GNA in inducing the apoptosis of B16 cells.

RESULTGNA showed a significant inhibitory effect in the growth and proliferation of melanoma B16 cells. The cell viability remarkably decreased with the increase of GNA concentration and the extension of the action time. The results of the Hoechst 33258 staining showed that cells processed with GNA demonstrated apparent apoptotic characteristics. Under the transmission electron microscope, B16 cells, after being treated with GNA, showed obvious morphological changes of apoptosis. The Western blot showed a time-dependent reduction in the p-PI3K and p-Akt protein expressions, with no change in p-PI3K and p-Akt protein expression quantities. The p-mTOR protein expression decreased with the extension of time, where as the PTEN protein expression showed a time-dependent increase.

CONCLUSIONGNA could inhibit the proliferation of melanoma B16 cells and induce their apoptosis within certain time and concentration ranges. Its mechanism in inducing the cell apoptosis may be related to PI3K/Akt/mTOR signaling pathways.

A maxillary first molar with 2 distinct palatal roots and an accessory canal was diagnosed by CBCT and microscope.An enamel protuberance at the cervical area was found.A properly usage of CBCT and microscope is helpful for the diagnosis and treatment of tooth with complex root canal system.

This paper is aimed to report the development of a method for the determination of the binding rate of plasma protein with salvianolic acid B. In vitro, equilibrium dialysis method was used to imitate the binding process between salvianolic acid B and plasma protein, in vivo, ultrafiltration method was used and the binding rate with HPLC was determined. Plasma samples were treated with methanol to precipitate the protein, and the buffer solution was directly determined after filtering. The calibration curve of the buffer solution was linear in the range of 0.5-20 microg mL(-1). The calibration curve of the plasma was linear in the range of 2-200 microg mL(-1). The extract recovery was 68.6%-81.9%. RSDs of intra- and inter-day precisions were all less than 8.5%. The binding rates of plasma protein with salvianolic acid B in vitro was 75.2% and in vivo was 92.1%. This paper shows the high binding power of salvianolic acid B to plasma protein with high sensitivity, good reproduction, simple management and fulfilling the requirement.
