Objective To detect the apoptosis and the intensity of proliferation in different types of renal pathology in children with lupus nephritis (LN), analyzed the relationship between apoptosis and proliferation in LN. Methods Twenty - seven children (aged 7-16 years old, 21 type IV and 6 type V ) with biopsy- proven LN and nine as controls were included in the study. Apoptosis was detected by in situ nick- end labeling techniques (TUNEL) in renal biopsy samples. Immunohistochemistry was employed to detect the proliferating cells identified by proliferating cell nuclear antigen (PCNA) and detect the expressions of proteins of apoptosis associated gene PDCD5 and Caspase - 3 in these patients. Results 1. Compared to type V LN, the patients with type IV LN had more apoptolic cells,more PCNA positive cells and higher ratios of PCNA/apoptosis (P/A) in glomeruli. 2. There were no difference in expression of PDCD5 in glomeruli in type IV LN compared with those in type V LN. Numbers of apoptotic cells were observed in glomeruli. The expression of Caspase- 3 in type IV LN increased in glomeruli compared with that in type V LN. Conclusions The up- regulation of mechanism of apoptosis in type IV LN was less than that of type V LN. Caspase- 3 participated in the apoptosis of glomeruli of LN, but PDCD5 did not play a role during apoptosis of glomeruli of LN or the effect of PDCD5 promoting apoptosis was depressed.

Objective To analyze the correlative factors of prognosis of neonatal stress-induced ulcer bleeding.Methods Fifty-four cases of NICU admitted stress-induced ulcer bleeding newborns were divided into mild group and severe group according to bleeding endurance,transfusion requirement,and clinical turnover.Compared with gender,gestational age,birth weight,and score for neonatal acute physiology(SNAP) Ⅱ and score for neonatal acute physiologyⅡ perinatal extension(SNAP-PE) Ⅱ of two groups.Results Based on the output of SPSS statistical package,the SNAP Ⅱand SNAP-PE Ⅱ had a significant deviation between two subgroups((?~2=)15.207,10.311 all P

Objective: To investigate the effect of ginseng polysaccharide on the gene expression profile of human erythroleukemia K562 cells cultured in vitro. Methods: The total RNAs treated with ginseng polysaccharide for 48 h were extracted from both K562 cells and the control K562 cells. All the RNAs were purified into mRNA and then convened to double-stranded cDNAs by reverse transcription. The cDNAs were labeled with a fluorescence dye Cy3 or Cy5 and hybridized to a Illumina whole-genome oligonucleotide microarray. The change in the gene expression profile of K562 cells following treatment with ginseng polysaccharide was analyzed by using bioinformatics. Results: A total of 306 differential genes were found. Of which 220 were up-regulated and 86 were down-regulated. Their biologic function was classified. Conclusion: Tumor cell differentiation is multiple genes comprehensive results, the screening of the genes may be meaningful for understanding tumorigenesis, tumor development, reverse polarization, and finding potential drug targets.

Objective:To analyze the influence factors of postoperative pregnancy in patients of endometriosis associated infertility after laparoscopy combined with hysteroscopy treatment.Methods:340 patients with endometriosis associated infertility who underwent laparoscopy combined with hysteroscopy treatment in Maternal and Child Health Care Hospital of Xiamen from April in 2012 to April in 2014 were followed up for 18 ～ 42 months to assess fertility outcomes.The relative factors of postoperative pregnancy rate were analyzed.Results:85.88％ (292/340) of patients were followed up,and the overall postoperative pregnancy rate was 56.51％.Among which the postoperative pregnancy caseswere 115 cases (39.38％),40 cases (13.70％),8 cases (2.74％),2 cases (0.68％) in the 1 ～ 6 months,7 ～ 12 months,13 ～ 24 months,25 ～ 42 months,respectively.There were significant differences among the four groups(x 2 =11.76,P ＜ 0.05).The multy-factors analysis showed that age ≥35,infertility time ≥3,r-AFS stage relatively high were risk factors of postoperative pregnancy(OR =10.45,3.03,3.74,P ＜0.05),and secondary infertility,applying ovarian stimulation treatment were the protective factors of postoperative pregnancy(OR =0.23,0.33,P ＜ 0.05).Conclusions:Laparoscopy combined with hysteroscopy treatment can increase postoperative pregnancy rate,and the best time to pregnancy is the first one year after treatment.The age ≥35,infertility time≥3,r-AFS stage relatively high are the important causes for the postoperative infertility,while applying ovarian stimulation treatment can promote pregnancy rate.

Objective To explore in vitro effects and the mechanism for FLAG regimen compared with IA regimen in P-glycoprotein-positive and -negative acute myeloblastic leukemia(AML) cell lines. Methods The expression of P-glycoprotein in K562 and K562/A02 cells were analyzed by flow cytometry. The effects of FLAG and IA on the proliferation of K562 and K562/A02 cells were detected by MTT assay. The Ara-CTP and Ara-C levels in those cells were measured by HPLC,the gene expression of hENT1 in K562 and K562/A02 cells was detected by real-time PCR. Results The positive rates of P- glycoprotein were (1.32±0.24)% in K562 cell and (97.66±3.77)% in K562/A02 cell, respectively. The expression of P- glycoprotein had no change after treated with FLAG or IA. The cytotoxicity to K562 of IA was better than FLAG [(84.41±9.33) % v.s (73.17±13.20)%, P<0.05], and the cytotoxicity to K562/A02 of FLAG was better than IA [(70.55±11.32)% v.s (48.46±12.81)%, P<0.01]. Ara-C and Ara-CTP accumulation and hENT1 expression in AML cells treated with FLAG were higher than that treated with IA. Conclusion P-glycoprotein-positive AML cells are more sensitive to FLAG regimen than IA regimen. The biochemical modulation of Ara-CTP and Ara-C may be the major mechanism.

This paper aimed to introduce and review the antioxidant and material base of selaginella medicinal plants.On the basis of the systematic identification of selaginella medicinal plants,we found that the ethyl acetate extract and flavonoids could inhibit the activity of XOD,LOX or/and COX-2 to some extent.Fourteen biflavonoids,one flavonoid and five flavonoid glycosides have been isolated from three resource plants,among them five compounds were firstly reported and fifteen compounds were firstly isolated in selaginella plants.Amentoflavone (AME),robustaflavone and robustaflavone-4''-dimethylether are three common characteristic constituents of selaginella plants,which can act as marks of common active ingredients and be applied to evaluate the quality of selaginella.Further studies found that some plants had stronger anti-Coxsackie virus and anti-tumor effects,and their mechanisms were associated with inhibiting multiple oxidase and mitigating harm of free radicals due to whole function.
