OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.

OBJECTIVETo investigate the expression of a novel metastasis-inducing protein human anterior gradient-2 (AGR2) in breast cancer and its clinical and prognostic significance.

METHODSAGR2 expression was assessed in 160 cases of breast cancer and 20 cases of benign breast diseases by immunohistochemistry using tissue chip technology. In addition the expression of ERa, PR and c-erbB-2 in breast cancer was also evaluated. Follow-up information of 5-year duration was available in 127 patients with breast cancer. Kaplan-Meier analysis and COX regression model were used to analyze the correlation between AGR2 expression and the follow-up clinical data.

RESULTSThe expression of AGR2 was significantly higher in breast cancers than that in benign diseases (68.3% vs. 25.0% , P < 0.01). There was a negative correlation between AGR2 expression and the histological grade of breast cancer (P <0.05) , whereas positive correlations was found between the expression of AGR2 and ERalpha (P <0.05), and between the expression of AGR2 and PR (P <0.01). In the subgroup of ERalpha-positive breast cancer, Logistic regression model demonstrated AGR2 and TNM stage were important factors affecting lymph node metastasis (both P < 0.01). Kaplan-Meier analysis demonstrated that a positive expression of AGR2 was associated with poor overall survival and relapse-free survival (both P <0.01). Moreover, COX regression model confirmed the expression of AGR2 as an independent prognostic factor among patients with ERa-positive breast cancer (P <0.01).

CONCLUSIONSThe abnormal expression of AGR2 may play a role in the pathogenesis and progression of breast cancer. The metastasis-inducing capability of AGR2 may be partly regulated through the ER pathway. Therefore, AGR2 may be a useful molecular marker for prognostication for patient with hormone-responsive breast cancer.

AIMTo study the effect of the recombined human growth hormone(rhGH) on secretory immunoglobulin A (sIgA), epidermal growth factor (EGF) in rats with obstructive jaundice.

METHODSSixty Wistar rats were randomly divided into four groups, sham-operated (group A), common biliary duct-ligated (group B), biliary duct-ligated plus rhGH-treat for one week (group C), biliary duct-ligated plus rhGH-treat for two weeks (group D), each group had 15 rats. Except group A, the rats of other groups were operated with biliary duct-ligated. Until two weeks after operation, the rats of group A and B were killed. After operation, the rats of group C were treated with rhGH hypodermic injection (0.75 U x kg(-1) x d(-1)) for one week, and then killed. The rats of D group were treated with rhGH hypodermic injection (0.75 U x kg(-1) x d(-1)) for two weeks, and then killed. All procedures were performed aseptically. Total bilirubin (TB), alkaline phosphatase (ALP), prealbumin(PA), insulin-like growth factor (IGF-1), sIgA, EGF were measured.

RESULTSCompared with group A, in group B, C, D, serum level of PA, IGF-1 and sIgA, EGF level of gastric and intestinal juice were lower, but TB, ALP were higher, there were significant difference. Compared with group B, the rats with treatment of rhGH in group C and D had higher sIgA and EGF and lower intestinal bacterial translocation.

CONCLUSIONIn objective jaundice rats, rhGH can protect their hepatic function, intestinal physical-barrier function and immune-barrier function, and reduce intestinal bacterial translocation.

BACKGROUNDMany researchers suggest that adult mammalian central nervous system (CNS) is incapable of completing self-repair or regeneration. And there are accumulating lines of evidence which suggest that endogenous neural stem cells (NSCs) are activated in many pathological conditions, including stroke in the past decades, which might partly account for rehabilitation afterwards. In this study, we investigated whether there was endogenous neural stem cell activation in intracerebral hemorrhagic (ICH) rat brains.

METHODSAfter ICH induction by stereotactical injection of collagenase type VII into globus pallidus, 5-Bromo-2 Deoxyuridine (BrdU) was administered intraperitoneally to label newborn cells. Immunohistochemical method was used to detect Nestin, a marker for neural stem cells, and BrdU.

RESULTSNestin-positive or BrdU-Labeled cells were predominantly located at 2 sites: basal ganglion around hemotoma, ependyma and nearby subventricular zone (SVZ). No positive cells for the 2 markers were found in the 2 sites of normal control group and sham group, as well as in non-leisioned parenchyma, both hippocampi and olfactory bulbs in the 4 groups. Nestin+ cells presented 4 types of morphology, and BrdU+ nucleus were polymorphologic. Positive cell counting around hemotoma showed that at day 2, Nestin+ cells were seen around hemotoma in model group, the number of which increased at day 4, day 7 (P <0.01), peaked at day 14 (P <0.05), and reduced significantly by day 28 (P <0.01).

CONCLUSIONEndogenous neural stem cells were activated in experimental intracerebral hemorrhagic rat brains.

OBJECTIVETo analyze expression characteristics of human skin epidermal stem cell at different developmental stages, and to explore its biological significance.

METHODSHealth skin samples from 28-32 w fetuses (F group), 4-12 y children (C group), and 35-55 y adult (A group) were harvested, with 10 cases in each group. Epidermis were separated using trypsin digestion and EDTA, and human epidermal stem cells were isolated and purified with type IV collagen attachment method. The monoclonal antibody of integrin beta1 and keratin 19 were used for detection and identification of epidermal stem cells by immunohistochemical staining. Total RNA was extracted from above cells by Trizol one-step method, and were detected by formaldehyde denaturing agarose gel electrophoresis. Probes were prepared and hybridized into cDNA microarray for scanning fluorescent signals and analysis of images, with two-fold differential expression value for screening. Significantly up/down-regulated genes were selected for verification by real time RT-PCR.

RESULTSBy comparing expression profile between A and C groups, a total of 1808 genes with differential expression were detected, including 1089 up-regulated genes and 719 down-regulated genes, and they were classified into 128 categories. Among them, 1462 genes were known (found in GeneBank), 346 genes were unknown. A total of 4534 genes with differential expression were detected between C and F groups, in which 1783 genes were up-regulated and 2751 genes were down-regulated, and they were classified into 216 categories. Among them, 3577 genes were known (found in GeneBank), and 957 genes were unknown. There were 1104 genes with differential expression consistently detected in F, C and A groups, which were classified into 32 categories according to gene function. Among them, 94 genes were consistently up-regulated and 75 genes consistently down-regulated. Test results of real time RT-PCR were in accordance with above-mentioned results.

CONCLUSIONSGene expression profiles of epidermal stem cells cultured in vitro, harvested from fetuses, children, and adult, exhibit obvious difference. This may be closely related to different stages of proliferation and differentiation of human epidermal stem cell and self-repair ability of wound at different developmental stages.

OBJECTIVEThis study is to understand the difference of semen quality among the different areas and the related factors.

METHODSFive hundred and sixty-two people were under from seven provinces.

RESULTSResults showed that the quantity and density of semen, the rate of moving forward semen, livability, percent age of normal formed semen and the total number of semen were statistically different among the seven areas. The difference was ranged as 28.82%, with the highest 2.95 ml in Shanxi province and the lowest 2.29 ml in Henan province. Geometric mean of semen density was found the lowest 36.27 x 10(6)/ml in Guizhou province, next to it was 42.52 x 10(6)/ml in Shandong province and the highest was 74.77 x 10(6)/ml in Hebei province. The percent age with forward progression of semen was seen the lowest 44.40% in Henan province, followed by 51.88% in Hebei province and 52.88% in Zhejiang province and the highest were 76.50% in Shanghai, 75.24% in Shanxi province, with a range of 72.30%. The highest semen viability was 85.89% in Shanghai, while the lowest 72.35% in Henan, with a range of 18.71%. Normal sperm morphology was seen the lowest 68.45% in Hebei province, with the highest 88.06% in Guizhou province, and the range was 28.65%. The geometric mean of total sperm count was seen the highest 204.23 x 10(6)/ml in Hebei province and the lowest 77.69 x 10(6)/ml in Guizhou province. Results showed through analysis of variance that some indexes were different in some provinces.

CONCLUSIONThe results indicated that the semen quality was different in different regions in China and its influential factors may be region and geography environment.
