Objective To compare the number of DARPP-32 positive cells yield in the grafts based on the application of single cell suspension by neural micro-transplantation technique and by traditional cell delivery technique and to explore effects and mechanisms of different approaches.Methods Cells derived from the whole ganglionic eminence of E15 rat embryos,ubiquitously expressing Green Fluorescent Protein(GFP) were implanted into unilaterally QA-lesioned rat striatum in a single-tract with an ultra-thin glass capillary with an outer diameter of 50 μm or using traditional cannula tip with a diameter of 500 μm.Results Histological assessment at 4 months after transplantation showed that there was about two-fold DARRP-32 positive striatal-like neurons in the micro-transplantation group(TT group) than that in the traditional group(MT group).Total graft volume was similar in both groups[(2.8±0.2) mm3 vs(2.5±0.4)mm3,F =0.25,P ＞ 0.05].And DARRP-32positive plaque volume[(0.6±0.1) mm3 vs(0.6±0.2) mm3,F =0.90,P ＞ 0.05]and TH staining plaque volume[(1.0±0.1) mm3 vs(0.7±0.1)mm3,F =1.44,P ＞ 0.05]also had the same performance in both groups.Number of DARRP-32 positive cells was calculated by Abercrombie correction formula,and the result showed that the number of DARRP-32 positive cells in MT group was two-fold of that in TT group[(20.1 ×103±1.2 × 103) vs(9.8 × 103±3.2 × 103),F =8.62,P ＜ 0.05].Higher DARRP-32 positive cells in MT group indicated that grafts had a better condition of growth and development.Conclusion Micro-transplantation approach can increase the number of new born striatal-like neurons,potentially due to the enlargement of the graft-host border area intensifying the graft's exposure to host derived factors and the minimized mechanical injury.

OBJECTIVETo compare the shear bond strength(SBS) of cast Co-Cr alloys and selective laser melting(SLM) Co-Cr alloys with those of dental porcelain.

METHODSA dental porcelain (Vita) was applied on cast and SLM Co-Cr alloy specimens (n = 10). SBS test was conducted, and fracture mode analysis was determined. Student's t-test by SPSS 13.0 software was employed to analyze the data.

RESULTSThe SLM Co-Cr alloy specimens had lower SBS values than the cast Co-Cr alloy specimens (P > 0.05). The metal-porcelain bond strength value of the cast group was (33.11 +/- 4.98) MPa, and that of the SLM group was (30.94 +/- 5.98) MPa. The specimens in both test groups exhibited mixed failure.

CONCLUSIONThe metal-porcelain system processed by SLM exhibit a bond strength that is similar to that of the cast group. This system also display a high precision.

Objective To observe the effect of acupuncture on cerebral glial fibrillary acidic protein(GFAP)expression of brain injury caused by intrauterine infection in neonatal rats.Methods Forty-three Wistar pregnant rats were divided into 2 groups:lipopolysaccharide(LPS)(n=35)and normal saline(n=8).Pregnant rats were consecutively injected intraperitoneally with LPS(450 ?g/kg)or saline on gestation 17 d and 18 d.LPS group were randomly divided into acupuncture group and model group.Acupuncture group were given acupunctured from 7 d to 21 d.GFAP expression was assayed with immunohistochemical technique.Results The number of GFAP immunoreaction(IR)strongly-positive neurons in the cerebral white matter was more in acupuncture group,less in model group and only very weakly IR-positive neurons were found in normal saline group.Conclusion Acupuncture can up-regulate the expression of GFAP in the cerebral white matter,which may contribute to the effect of acupuncture in improving brain injury caused by intrauterine infection.

Objective: To investigate the immunosuppressive components in Leigongteng Duogan Tablet (LDT). Methods: High performance liquid chromatography (HPLC) was applied to establish the fingerprint for LDT from seven manufactures. The immunosuppressive effect of LDT was observed on Con A-induced mice spleen cells, and the cell proliferation and contents of IFN-γ were recorded. Then the partial least squares regression (PLSR) analysis was used to investigate its spectrum-effect relationship. Results: The HPLC fingerprint for LDT from seven manufactures was established, and 18 characteristic peaks were confirmed. The in vitro cell experimental results showed that the proliferation of mice spleen cells and secretion of IFN-γ were inhibited by all LDT significantly compared with the control group. According to the results of PLSR, No. 1, 2, 6, 7, 17, and 18 peaks were strongly related to the proliferation inhibition of mice spleen cells and No. 1, 2, 6, 7, 8, 9, 12, and 13 peaks were related to the secretion of IFN-γ. Conclusion: The No. 1, 2, 6, 7, 8, 9, 12, 13, 17, and 18 peaks are the principal immunosuppressive substances in LDT.

The expression of Attractin mRNA and protein in testis and semen of human and male mice was investigated. Human testis and semen samples were all collected from Reproductive Center of Renmin Hospital, Wuhan University in December, 2012. Testis samples were collected from 7 cases of obstructive azoospermias when they were subjected to diagnosed testis biopsy, and 30 normal human semen samples were obtained from those cases of semen analysis. Adult mice testis tissues were obtained from 10 2-month-old male BALB/c mice, and 60 male mice at different ages were classified into 10 groups (day 1, 5, 10, 15, 21, 28, 35, 42, 56, and 120 respectively, n=6 each). The expression of Attractin mRNA and protein in testis was detected by RT-PCR and Western blotting respectively. Human semen samples were centrifuged into sperm plasma (SP) and sperm extract (SE), and mice sperm samples were collected from the epididymis of 10 adult male BALB/c mice. Western blotting was used to determine the Attractin protein expression level. Attractin mRNA and protein were expressed in the testis of both patients with obstructive azoospermias and adult Bcl/B mice. Quantitative RT-PCR revealed that no Attractin mRNA was detectable in day 1 male BALB/c mice group. The Attractin mRNA and protein levels were low on the day 10, and increased with age until day 56. On the day 120, the expression levels of Attractin were decreased. As for human semen samples, Attractin protein was expressed in both SP and SE, but didn't exist in samples from the epididymis of male BALB/c mice. It was suggested that Attractin acted as a novel active substance and was involved in male reproduction in both human and BALB/c mice, but it exerted a different expression profile in different mammal species.

Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.
