Objective To explore the relationship of the ratio of plasma adrenomedullin(AM)and endothelin-1(ET-1)with serum concentration of neuron-specific enolase(NSE)in full-term neonates with hypoxic-ischemic encephalopathy(HIE).Methods Plasma concentrations of AM,ET-1 and serum NSE from 32 full-term neonates with HIE were detected by radioimmunoassay(RIA)on the 1,3 and 7 d after parturition,30 neonates in the corresponding periods in our hospital were employed as controls.The infants with HIE were divided into mild,moderate or severe group in terms of diagnostic standard of HIE.Results 1.Plasma concentrations of AM and ET-1 in newborns with mild,moderate or severe HIE were significantly higher than that of control group at 1 d after life with a decline from 3-7 d(Pa

Objective To explore the effect of exogenous adrenomedullin(ADM) on expressions of glutathion in plasma and brain tissue inneonatal rats with hypoxic-ischemia reperfusion brain damage(HIRBD) and the mechanism of action.Methods Fifty-six cases of 7 d SD rats were randomly divided into 4 groups including normal control group(without any treatment),HIRBD group(the model with hypoxia for 2 h and ischemia for 1 h),primed group(abdomen infusion of ADM at 0.5 h before making model,the other was same to the HIRBD group)and treatment group(abdomen infusion of ADM at onces after making model,the other was same to the HIRBD group).The neonatal rats in 4 groups were derived blood and brain tissue after decapitation at either 4 h or 24 h after reperfusion.The levels of gtutathion(GSH) in plasma and brain tissue were determined by using chromatometry.Results In HIRBD group,the affection areas at 24 h after reperfusion enlarged compared with those at 4 h after reperfusion.Meanwhile,the affection of punctiform degeneration or necrosis at 4 h after reperfusion transformed into the affection of lamellar or diffuse degeneration or necrosis at 24 h after reperfusion.The levels of GSH in plasma and brain tissue in HIRBD group at either 4 h or 24 h after reperfusion were significantly lower than that in normal control group(Pa0.05).Meanwhile the pathology score of brain section in primed group and treatment group were significantly lower than that in HIRBD group at either 4 h or 24 h after reperfusion(Pa0.05).Conclusion Exogenous ADM can induce the neuroprotection in HIRBD by adjusting the expression of GSH.

Based on the conserved region nucleotide sequences of five potato viruses/viroid(Alfalfa Mosaic Virus,ALMV;Cucumber mosaic virus,CMV;Cucumber mosaic virus-satellite,CMV-sat;Potato virus Y,PVY;Potato spindle tuber viroid,PSTVd) and one inner control(18S rRNA),the microarray containing specific oligonucleotide probes and PCR probes were designed and fabricated.The effects of probe concentration,hybridization time,hybridization temperature and spotting solutions on microarray hybridiazation were evaluated.Finally the specificity of optimized plant virus detection array was validated.No significant effect on hybridization signal intensity was observed when the concentration of the oligonucleotide probes ranged from 5 to 20 ?mol/L,there was a linear relationship between the concentration of PCR probe and hybridization signal intensity.The greatest signal intensity were obtained when hybridized at 45℃ for 4 h,and the oligonucleotide probes and PCR probes had a similar effect on microarray hybrization.Among the different spotting solutions,DMSO produced a good reproducibility.The plant virus could be detected specifically by oligonucleotide probe microarray and PCR probe microarray after optimization.

OBJECTIVETo observe the therapeutic effect of Qilin Pills combined with clomiphene on idiopathic oligoasthenospermia.

METHODSWe randomly assigned 300 patients with idiopathic oligoasthenospermia to a trial (n = 156) and a control group (n = 144) to be treated with Qilin Pills (6 g, tid) combined with clomiphene (50 mg, qd) and clomiphene alone (50 mg, qd), respectively, both for a course of 12 weeks. Before and after 4, 8, and 12 weeks of medication, we determined sperm concentration, the percentages of grade a and grade a + b sperm, sperm motility, and the levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone (T), followed by evaluation of the clinical efficacy of Qilin Pills with the pregnancy rate in the patients' spouses as the secondaty therapeutic indexes.

RESULTSCompared with the baseline, both groups of patients showed remarkably improved semen parameters and hormone levels after treatment (all P < 0.01). After 4, 8, and 12 weeks of medication, statistically significant differences were observed between the trial and control groups in sperm concentration ([17.06 ± 2.24] vs [15.07 ± 2.48], [22.10 ± 2.65] vs [18.11 ± 2.97], and [28.13 ± 3.59] vs [21.21 ± 3.60] x 10(6)/mL, P < 0.01), the percentage of grade a sperm ([15.03 ± 2.39] vs [13.08 ± 2.51], [21.08 ± 3.16] vs [16.04 ± 3.05], and [28.08 ± 4.70] vs [20.14 ± 4.74]%, P < 0.01), the percentage of grade a + b sperm ([30.10 ± 5.07] vs [26.21 ± 3.96], [38.08 ± 5.64] vs [30.07 ± 4.80], and [48.04 ± 6.49] vs [35.28 ± 4.77]%, P < 0.01), sperm motility ([42.04 ± 4.86] vs [40.29 ± 4.19], [52.05 ± 5.58] vs [48.03 ± 4.40], and [65.03 ± 5.13] vs [56.67 ± 4.99]%), the FSH level ([7.75 ± 1.38] vs [7.20 ± 1.17], [10.83 ± 1.23] vs [9.10 ± 1.32], and [14.22 ± 0.84] vs [12.06 ± 1.45] IU/L, P < 0.01), the LH level ([10.05 ± 1.68] vs [9.18 ± 1.54], [13.96 ± 1.68] vs [11.99 ± 1.71], and [19.01 ± 2.42] vs [15.86 ± 2.08] IU/L, P < 0.01) and the T level ([19.19 ± 192] vs [18.34 ± 1.79] [21.06 ± 1.63] vs [20.06 ± 1.56], and [24.63 ± 1.06] vs [22.03 ± 1.49] nmol/L, P < 0.01). The pregnancy rate in the patients' spouses was significantly higher in the trial than in the control group at 4, 8, and 12 weeks (1.92 vs 0.69, 4.81 vs 3.47, and 11.54 vs 8.33%, P < 0.01). There were no statistically significant differences in drug tolerance between the two groups (P > 0.05). No obvious adverse reactions were observed.

CONCLUSIONQilin Pills combined with clomiphene can evidently improve the seminal quality and hormone level of oligoasthenospermia patients with no obvious adverse events. However, its long-term efficacy and tolerance deserve further clinical investigation.

OBJECTIVETo investigate the pro-apoptotic effect of Her-2 targeted recombinant caspase-6 fusion protein on osteosarcoma SOSP-9607 cells.

METHODSRecombinant immunocasp-6 was generated by sequential fusion of the genes of a signal peptide, a single-chain Her-2 antibody (e23sFv), a PEA translocation domain (PEA aa253-364) and an active caspase-6. The immunocasp-6 gene was cloned into pCMV plasmid to construct a kind of eukaryotic expression vector, i.e. pCMV-e23sfv-PE II-caspase-6 (abbr. pCMV-6) and transfected into SOSP-9607 cells. Murine xenograft models were randomly divided into two groups that received i.m. injections of liposome encapsulated pCMV-6 or pCMV alone. The tumor volume and weight of the nude mice and the tumor weight of the cured mice were observed and statistically analyzed. The morphological changes of the tumors were examined with HE staining, apoptotic morphology of the tumor was observed by TUNEL staining and the gene expression was analyzed by immunohistochemical staining.

RESULTSThe tumor growth of the mice in the treatment group was significantly slower than that of the control group (P = 0.001). The weight of the nude mice in the treatment group was significantly higher than that of the control group (P = 0.0002). The tumor weight of the mice in the treatment group was significantly lower than that of the control group (P = 0.0006). HE and TUNEL staining of the tumor of nude mice in the treatment groups showed typical characteristics of apoptosis, while normal structure was found in the control group. Furthermore, caspase-6 was not found in the tumor and muscle tissues in the control group, but only in the treatment group by immunohistochemistry.

CONCLUSIONImmunocasp-6 can selectively recognize and bind to and kill HER-2 positive osteosarcoma cells, therefore, to offer some foundation for the clinical treatment of osteosarcoma.
