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.

Objective To observed hepatolenticular degeneration gene (ATP7B gene) expressed in Me32aT22/2L cell and detected whether A TP7B could transport redundant copper and reduce copper-induced cell apoptosis, which will make the basement for future gene therapy. Methods Piasmid pRc/CMV-WD containing A TP7B cDNA was transfected into Me32aT22/2L cell using lipofectamin2000 transfection methods. Intracellular distribution of ATP7B was detected by immunofluorescence histochemistry method and copper transportation function was studied using high-concentration copper incubation experiments, meanwhile, cell apoptosis induced by high-concentration copper incubation was observed. Results Expression of A TB7B gene could be detected and located around nuclei within the Me32aT22/2L cell. After incubation of high- concentration copper solution after 24, 48 and 72 hours, in empty vector group intracellular copper content was (600.60±69.71) ng/mg, (890.72±65.74) ng/mg and (1189.20±85.71) ng/mg respectively, however, intracellular copper content was (351.33±49.86) ng/mg, (427.38±30.95) ng/mg and (539.10±34.91) ng/mg in A TP7B group. Comparison of two groups has a statistical significance (P<0.01). Meanwhile, cell apoptotic rate was markedly decreased in A TPTB group compared with empty vector group (P<0.01). Conclusion Exogenous A TP7B gene could be expressed in Me32aT22/2L cell and A TPTB could transport intracellular redundant copper, subsequently reduced copper-induced cell apoptosis.

OBJECTIVETo investigate the protein expression of cyclooxygenase 2 (COX-2) and nuclear factor kappa B (NF-kappaB) in gastric mucosa-associated lymphoid tissue (MALT) lymphoma and its clinical significance.

METHODSProtein expression of COX-2 and NF-kappaB in gastric MALT lymphoma were examined by immunohistochemistry of Envision two-step method. The correlations of COX-2 and NF-kappaB expression with Helicobacter pylori (Hp) infection, clinical stage, depth of tumor invasion, tumor size, recurrent rate and treatment were analyzed by univariate, multivariate and Pearson analysis.

RESULTSThe positive expression of COX-2 and NF-kappaB in gastric MALT lymphoma were 48.9%(23/47) and 36.2% (17/47) respectively, and a positive correlation was found between these two factors(r=0.326,P<0.05). Moreover, COX-2 expression was positively correlated with Hp infection,clinical stage, depth of invasion and tumor size (P<0.05). Univariate analysis showed that the overall survival of gastric MALT lymphoma patients with positive COX-2 protein (59.9 months) was shorter than that of patients with negative COX-2 protein (77.8 months), but the difference was not significant (P>0.05). The survival was significantly shorter in gastric MALT lymphoma patients with positive NF-kappaB protein (26 months) than that of patients with negative NF-kappaB protein (123.2 months)(P<0.05). Multivariate Cox regression analysis revealed that clinicopathological stage was independent prognostic factor, and associated with short survival.

CONCLUSIONUp-regulated expression of COX-2 and activation of NF-kappaB are associated with Hp infection in gastric MALT lymphoma, and their protein expression is correlated with the development of tumor and prognosis.

OBJECTIVETo study the difference of plasma actual bicarbonate between the children with growth hormone deficiency (GHD) and idopathatic short stature (ISS) and to value the plasma bicarbonate standard deviation scores (SDS) in diagnosis of GHD.

METHODSForty-seven short stature children were divided into two groups (GHD and ISS) according to the peak GH response to provocative test. Plasma actual bicarbonate concentrations anion gap (AG), base excess and electrolytes were measured in 47 children with short stature before GH provocative tests.

RESULTSThe mean plasma actual bicarbonate concentrations, bicarbonate SDS were (22.60+/-1.29)mmol/L and -0.27+/-0.98 respectively in GHD children, which were significantly lower than those of ISS children (P<0.01), whereas AG was higher than that of ISS children [(11.73+/-4.52 vs 7.87+/-1.70) mmol/L], P<0.01. Seventy-two percent of patients with bicarbonate SDS

CONCLUSIONPlasma actual bicarbonate concentrations and bicarbonate SDS are lower in patients with GHD than those in patients with idopathatic short stature. Evaluation of plasma bicarbonate SDS of short stature children can predict the probability of GHD, especially when bicarbonate SDS is less than 1 s.

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.
