OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

OBJECTIVETo find out the relationship between mutation of ATP7B gene promoter region and pathogenesis of Wilson disease(WD).

METHODSTwo of 48 WD patients presented C-->T base substitution mutations at the position -183. DNA sequences of the promoter region from normal and mutant samples were separated. The fragments containing the promoter region were cloned upstream of the luciferase. Luciferase activity was analyzed.

RESULTSThe luciferase activity of reporter gene containing normal sequence of ATP7B gene promoter region did not show significant difference as compared with that of reporter gene containing mutant promoter(n=3, P > 0.05).

CONCLUSIONNo influence of C-->T base substitution mutations on the activity of promoter was observed in study. The results suggest that WD pathogenesis relates little to the mutations of the promoter region in Chinese.

OBJECTIVETo investigate the local cellular immune response after injection of superantigen, the highly agglutinative staphylococin (HAS), into the tumor bed after ultrasound-guided percutaneous microwave coagulation therapy (PMCT) in the liver cancer patients.

METHODSNinety-two patients with pathologically proven primary liver cancer were divided into two groups: 45 in group A were treated by PMCT alone and 47 in the group B by combined with ultrasound-guided percutaneous injection of highly agglutinative staphylococin (HAS). Before and after PMCT and HAS treatment, the patients underwent ultrasound-guided percutaneous biopsy from the tumor bed and the samples were examined by pathology and immunohistochemistry. The infiltration of CD3+, CD4+, CD57+ and CD68+ lymphocytes in treatment zone was compared between the two groups. Moreover, the infiltrating immunocytes were observed by transmission electron microscopy.

RESULTSOne week after HAS injection, the densities of CD3+, CD4+, CD57+ and CD68+ cells in the group B were 54.50 +/- 18.44, 38.14 +/- 12.44, 33.38 +/- 10.79 and 45.56 +/- 16.53, respectively. All the above mentioned parameters increased significantly in varying degrees compared with that before PMCT or HAS injection (P < 0.05). Four weeks after HAS injection, the density of CD3+, CD4+, CD57+ and CD68+ cells in the group B were 32.67 +/- 10.42, 23.43 +/- 6.99, 18.63 +/- 7.89 and 30.01 +/- 11.05, respectively, still significantly higher than those before PMCT (P < 0.05). Five weeks after PMCT and HAS injection, the densities of CD3+, CD4+, CD57+ and CD68+ cells in the group B were 54.50 +/- 18.44, 38.14 +/- 12.44, 33.38 +/- 10.79 and 45.56 +/- 16.53, versus 32.03 +/- 8.11, 15.67 +/- 8.32, 15.23 +/- 8.26 and 29.67 +/- 11.98 in the group A, respectively, still with a significant difference between the two groups (P < 0.05). A lot of lysosomes, endoplasmic reticulum and mitochondria in the immune cells after injection of HAS were observed by transmission electron microscopy.

CONCLUSIONThe local cellular immunity in liver cancer treatment area can be significantly improved by ultrasound-guided injection of highly agglutinative staphylococin after percutaneous microwave coagulation therapy.

OBJECTIVETo analyze the maltose clearance in plasma and urine of healthy volunteers with high-performance liquid chromatography.

METHODSMaltose solution was infused to 12 healthy volunteers during a 4-hour period at an infusion rate of 0.2, 0.3, and 0.5 g/(kg x h), Plasma and urine specimens were collected at different time points before and after infusion, and then analyzed with high-performance liquid chromatography.

RESULTSThe coefficients of variation of the precision and accuracy of the analysis method ranged 3.68%-4.58% and 0.44%-4.83% for plasma, respectively, and 2.91%-7.62% and 0.95%-8.27% for urine, respectively. The plasma maltose concentration increased in a dose-dependent manner (r > 0.99). The plasma maltose concentrations returned to the baseline levels 12 hours later. Two hours after injection, the urinary excretion of maltose increased, reached the peak value within 2-4 hours, began to decrease 6 hours later, and became zero 24 hours later.

CONCLUSIONSAn infusion rate of 0.2-0.5 g/(kg x h) of maltose will not remarkably increase the blood glucose level in healthy people. The routine infusion rate should below 0.3 g/(kg x h), unless an emergency exists.
