Objective To explore the mechanism of Zibu Piyin Recipe (ZBPYR) on spleen yin deficiency diabetes-associated cognitive disorder (DACD). Methods The rats were randomly divided into control group, diabetes mellitus (DM) group, spleen yin deficiency group, spleen yin deficiency DM group and spleen yin deficiency DM+ZBPYR group (treatment group). Type 2 DM models were established by high-fat food feeding and low dose STZ intraperitoneal injection for 4 weeks. Then the classical compound method was used to construct spleen yin deficiency rat models by improper diet, over exertion and yin fluids exhaustion. The treatment group was given ZBPYR by gavage for 15 days, and the other groups were given the same amount of normal saline. Then cerebral cortex, hippocampus, stomach and liver were obtained and the changes of protein expression of PDHE1α in them were observed by Western Blot. Results The protein expression of PDHE1αin cortex of DM group and spleen yin deficiency DM group were lower than control group (P<0.05). PDHE1α expression of treatment group in cortex and stomach increased more significantly than spleen yin deficiency DM group (P<0.05). The expression of PDHE1α protein showed no significant difference among all groups in hippocampus and liver. Conclusion ZBPYR improved spleen yin deficiency DACD by regulating PDHE1αin cortex and stomach.

Objective To express and purify Chlamydial protease-like activity factor(CPAF)from Chlamydophila pneumoniae,for investigating the effect of its recombinant protein GST-CPAF in inducing human monocytic cells to secrete proinflammatory cytokines and cell apoptosis.Methods The recom-bination expression plasmid pGEX6p-2/CPAF from Chlamydophila pneumoniae was transformed into E.coli.The recombination GST-CPAF was expressed after induction by IPTG,and purified by a agarose gel FF.Human monocytic cells were stimulated by the GST-CPAF to test the production of tumor necrosis factor a(TNF-α)and interleukin-6(IL- 6)by ELISA.Inhibition of cells proliferation with GST-CPAF was assessed by MTT.The THP-1 cell apoptosis stimulated by GST-CPAF was detected by Hoechst33258 fluorescence staining,DNA fragmentation analysis and cell apeptosis was detested bv Annexin V-FITC-propidiuum iodide (PI)staining.Results The recombination protein GST-CPAF was successfully expressed with high level in E.coli,and stimulated human monocytic cells to produce proinflammatory cytokines including TNF-α and IL-6 in a dose-and time-dependent manner.Otherwise,the GST-CPAF inhibited the growth of human monocytic cell in a dose-dependent manner.Apoptosis with nuclear chromatin fragmentation as well as cell shrinkage was observed by fluorescent staining and microscopy,DNA ladders in apoptosis cells were detected after 24 h with the GST-CPAF.Conclusion The GST-CPAF from Chlamydophila pneumoniae can induce the secretion of proinflammatory cytokines TNF-α and IL-6 by human monocytic cells,and inhibited the proliferation of THP-1 cell and apoptosis in vitro.

This study was aimed to observe changes of key molecular in insulin signaling pathway in the hypothala-mus of rats to explore the mechanism of spleen yin deficiency diabetes-associated cognitive decline (DACD) and Zibu Piyin Recipe (ZBPYR) in order to provide new ideas and new clues for treatment of DACD. Rats were randomly divided into five groups, which were the control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and the ZBPYR group. Insulin receptor substrate 1 (IRS-1) serine phos-phorylation levels and protein kinase B (PKB/Akt) serine phosphorylation levels which were involved in the insulin signaling were observed by western blotting in the hypothalamus to determine whether there were insulin signaling obstacles in the hypothalamus of rats. The results showed that the expression of p-IRS-1ser in the DM group, pi group and piDM group was increased compared with the Cont group (P< 0.05); while the p-Akt expression of the DM group and piDM group was decreased (P< 0.05). The expression of p-IRS-1ser in the ZBPYR group decreased compared with the DM group and piDM group (P< 0.05); while the level of p-Akt increased compared with the DM group and piDM group (P < 0.05). It was concluded that insulin signaling was not transduced normally in the hy-pothalamus of the DM group, pi group and piDM group. Insulin resistance may occur in the hypothalamus. And ZBPYR can correct insulin signaling transduction disorder.

This study was aimed to observe different forms of β-amyloid peptide (Aβ) and insulin degrading enzyme (IDE) in the hippocampus and cortex in order to further explore the role of Aβ and IDE on spleen yin deficiency di-abetes-associated cognitive decline (DACD), and the effect of Zi-Bu Pi-Y in method. The rats were randomly divided into five groups, which were the blank control (Cont) group, diabetes (DM) group, spleen yin deficiency (pi) group, spleen yin deficiency diabetes (piDM) group and Zi-Bu Pi-Y in recipe (ZBPYR) group. Soluble and insoluble Aβ in the hippocampus and cortex of rats were extracted by gradient centrifugation, and then measured by ELISA. The ex-pression of IDE was observed by western blot. The results showed that the content of soluble and insoluble Aβ1-42 in the hippocampus and cortex of the DM group and piDM group were higher than the Cont group. The soluble and in-soluble Aβ1-42 content in the hippocampus and cortex of the ZBPYR group were reduced compared with the DM group and the piDM group. The soluble Aβ1-40 in the cortex of the DM group, pi group and piDM group were in-creased compared with the Cont group (P < 0.05). The soluble Aβ1-40 content of the ZBPYR group was decreased compared with the DM group and the piDM group (P < 0.05). The expression of IDE protein was decreased in the hippocampus of the DM group and the piDM group compared with the Cont group (P< 0.05), and the IDE protein level in the hippocampus of the ZBPYR group was increased compared with the DM group and the piDM group (P<0.05). The expression of IDE protein in the cortex of the DM group, pi group and piDM group was lower than the Cont group (P< 0.05). The IDE protein level in the cortex of the ZBPYR group was reduced compared to the DM group (P< 0.05). It was concluded that the increased Aβ1-42 in brain may be a major pathological change of DACD and spleen yin deficiency DACD. The decreased IDE expression may be one of the reasons to induce increasing of Aβ1-42 level. The Zi-Bu Pi-Y in method may decrease the Aβ1-42 content by upregulating IDE protein expression.

OBJECTIVETo discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures.

METHODSFrom January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score.

RESULTSAll the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found.

CONCLUSIONExternal fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

Objective To clarify the pathogenesis of spleen yin deficiency diabetes-associated cognitive decline (DACD) and mechanism of Zinu Piyin Recipe (ZBPYR) by observing the expression of phosphorylated RNA-dependent protein kinase-like endoplasmic reticulum kinase (PERK), eukaryotic initiation factor 2α subunit (eIF2α), p-eIF2α, glucose-regulated protein 78 (GRP78) in cerebral cortex of spleen yin deficiency diabetes mellitus rats. Methods The rats were randomly divided into control group, diabetes mellitus group, spleen yin deficiency group, spleen yin deficiency diabetes mellitus group (disease-syndrome group) and spleen yin deficiency diabetes mellitus+ZBPYR group (treatment group). Type 2 diabetes mellitus models were established by high-fat food feeding for 4 weeks and low dose STZ intraperitoneal injection. Then the classical compound method was used to construct spleen yin deficiency rats model by improper diet, over exertion and yin fluids exhaustion. The reatment group was given ZBPYR and other groups were given equal volume of normal saline for 15 days, then cerebral cortex was obtained. The expression of p-PERK, p-eIF2α, eIF2α and GRP78 were observed by Western Blot and RT-PCR. Results The protein expression of p-PERK, p-eIF2α, and mRNA expression of GRP78 of diabetes mellitus group, spleen yin deficiency group and disease-syndrome group was enhanced compared with control group (P<0.05). GRP78 protein expression of diabetes mellitus group, disease-syndrome group was increased compared with control group (P<0.05). The protein expression of p-PERK, p-eIF2α, GRP78 and mRNA expression of GRP78 of treatment group was decreased compared with diabetes mellitus group and disease-syndrome group (P<0.05). Conclusion Endoplasmic reticulum stress is involved in spleen yin deficiency DACD. ZBPYR improves learning and memory ability by reducing endoplasmic reticulum stress.

Objective To investigate the mechanism and suppression effect of human cytomegalovirus (HCMV) on proliferation of megakaryocyte progenitors(CFU-Mk)in vitro.Methods Colony forming unit-assay was applied to observe the effect of HCMV-AD 169 strain on CFU-Mk of cord blood. The technique of PCR was used to demonstrate the existence of HCMV-AD 169 DNA in the colony cells of cultured CFU-Mk.Results 1.The number of CFU-Mk colonies in HCMV-infected groups decreased significantly compared with that of control group. The CFU-Mk formation was inhibited significantly after HCMV-AD 169 strain infection.The suppression effect showed a dose-dependent fashion: 46.7 % inhibition with 10 -1of HCMV, 29.7 % with 10 -2 and 14.5 % with 10 -3 in the CFU-Mix assay. The peak of CFU-Mk colonies (d16-18) was not significantly different between control group and experimental groups, but the duration of the CFU-Mk colonies in infected groups was significantly shorter than that in control group.2. HCMV-DNA was positively detected in the colony cells of viral infected group by PCR, while negative in control group.Conclusions HCMV-AD 169 strain may inhibit the differentiation and proliferation of CFU-Mk by infecting the hematopoietic progenitors. HCMV may cause the suppression of hematopoiesis by direct infection, which may be the main reason for HCMV infection associated with thrombocytopenia.
