This study was aimed to explore the characteristics of urine metabolomics among HIV/AIDS patients with spleen-lung qi-deficiency. H-NMR technique was combined with principal component analysis and cluster analysis in the comparison of urine metabolic products among 24 HIV/AIDS cases with spleen-lung qi-deficiency and 20 healthy control cases. The results showed that urine metabolic products of HIV/AIDS patients with spleen-lung qi-deficiency and healthy people by H-NMR technique detection and PLS-DA analysis can classify the outline of urine metabolites. There were about 20 variables in the difference between two groups. The speculated substances contained glycyl-L-leucine, L-valine, α-aminobutyric acid, methyl succinic acid, glycine propionyl, and etc. It was concluded that H-NMR technique was able to classify the outline of urine metabolites between HIV/AIDS cases with spleen-lung qi-deficiency and healthy people. Part of the potential existed characteristic markers contributed to the clinical diagnosis of traditional Chinese medicine (TCM) syndrome differentiation of AIDS. It had certain effect in its quantitative analysis.

OBJECTIVE To analyze trimethylation of genome-wide histone H3 lysine 4(H3K4met3) induced by silicon dioxide(SiO2)through chromatin immunoprecipitation linked to microarrays(ChIP-chip)in lung fibroblast(LF)of rats. METHODS A primary co-culture model of rat alveolar macrophages (AM)and LF in vitro. AM were exposed to 100 mg · L-1 free SiO2 for 24 h,before LF were collected and the phenotype of LF was determined after transdifferentiation by immunohistochemistry. ChIP-chip was used to profile the variations of trimethylation in H3K4 of lung fibroblasts in CpG island regions. ChIP-qPCR was used to validate the microarray results. The mRNA expression of nfib and kpna3 was analyzed by qRT-PCR. RESULTS Totally 1815 (518 increased and 1297 decreased) genes of H3K4met3 displayed significant differences in SiO2 100 mg·L-1 group compared with control group(Cy3/Cy5 value>2.0 or <0.5,NimbleScan V2.5 software). The results of ChIP-qPCR were quite consistent with those of microarray. CONCLUSION There are significant differences in methylation of genome-wide H3K4 between SiO2 100 mg·L-1 group and control group. These novel candidate genes may become potential biomarkers or new interfered targets.

OBJECTIVETo seek possible effect targets of bufalin in HeLa cells by studying the impact of bufalin on cell protein expression profile after treatment on human cervical carcinoma cell lines HeLa.

METHODBufalin's ICs0was measured by MTr assay. The apoptosis of cells was observed by FCM (flow cytometry) and Hoechst 33342 staining assay. Differentiated expression protein spots were founded and identified using proteomic techniques, which could induce HeLa cell apoptosis.

RESULTBufalin showed remarkable cytotoxic effect on HeLa cells. IC50 (154 +/- 21.5) nmol X L(-1) indicated the possibility of inducing cell apoptosis. The protein expression profile showed 11 differentiated expression protein spots. Among the 11 proteins, nudix-type motif 5, vimentin, hnRNP C1/hnRNP C2 variant, HNRPK, HNRPK isoform a variant (two spots are the same protein), heat shock protein 27, macrophage-capping protein, SELENBP1 protein were down-regulated, while ribosomal protein, large, P0 and S-adenosylmethionine synthetase 2 were up-regulated by bufalin treatment. They may be effect targets of bufalin in HeLa cells. Western blotting showed consistent results in heat shock protein 27, vimentin and HNRPK between expression after treatment with bufalin and two-dimensional electrophoresis.

CONCLUSIONBufa-Lin can induce apoptosis in human cervical carcinoma cells HeLa and the effect of bufalin may be related to the joint intervention with multiple protein targets.

Proteasome is a multi-subunit protease complex in eukaryocytes, and plays an important role in ubiquitin-proteosome pathway. Recombinant proteasome can be used to screen proteasome inhibitors. In this study, recombinant plasmid of pET28a-PSMB1 was constructed by inserting human proteasome catalytic subunit (PSMB1) cDNA (726 bp) into the prokaryotic expression vector pET28a(+), and transforming the plasmid into E. coli BL21(DE3) cells for expression. After overnight induction (1 mmol/L IPTG, 20 degrees C), an expected protein band with molecular weight of 27 kDa was observed on SDS-PAGE gel. The recombinant protein was then purified through affinity chromatography, and the purity is more than 95%. The amino acid sequence of the recombinant protein was validated by NanoLC-MS/MS. The data from in vitro BIAcore analysis showed that the recombinant PSMB1 could bind to celastrol. The binding affinity between PSMB1 and 10 micromol/L celastrol was more than 27RU.

The structure and biological function of CXCL12/CXCR4 are the basis of physiological and pathological function.Combination of HIV-1 envelope protein and CXCR4 will promote the entry of virus into host cells.CXCL12 can reduce the number of CXCR4 through rapid endocytosis and inhibit the replication and transmission of HIV.The interaction of CXCL12/CXCR4 axis with in-flammation and autophagy plays an important role in HIV infection.Previous research has found that gene expression profiles of differ-ent TCM syndromes of acquired immunedeficiency syndrome(AIDS)are different.CXCR4 has different expression in AIDS,lung and spleen qi deficiency syndrome,Qi Yin deficiency syndrome and dampness heat syndrome,which is related to chemokine signaling pathway;the differential gene CXCR4 in peripheral blood of AIDS patients with lung and spleen qi deficiency syndrome is related to au-tophagy process.According to the intervention of Yiaikang Capsule,CXCR4 expression is increased,indicating that Yiaikang Capsule can regulate the expression of autophagy related genes.Research on the role of CXCL12/CXCR4 in TCM syndromes of AIDS is condu-cive to better play the therapeutic advantages of TCM and provide a new direction for gene targeted therapy.

BACKGROUND:The combination of platelet-rich fibrin and autogenous bone has achieved good results in the treatment of periodontal bone defects,but the study of the combination of the two in the treatment of severe alveolar bone defects is scarce. OBJECTIVE:To observe the effect of autologous bone transplantation plus platelet-rich fibrin on the repair of severe alveolar bone defects. METHODS:A total of 102 patients with severe alveolar bone defects in Hengshui People's Hospital from April 2022 to February 2023 were selected and divided into control and observation groups(n=51 per group)by random number table method.Guided tissue regeneration was performed in both groups.The bone defect was filled with autogenous bone in the control group,and the observation group underwent platelet-rich fibrin+autogenous bone filling for bone defects during the operation.The clinical efficacy,changes in tooth mobility,periodontal microecological environment(probing depth,clinical attachment loss,and bleeding index),height and density of alveolar bone,gingival crevicular fluid indicators(transforming growth factor-β,serine protease inhibitor,and matrix metalloproteinase-3)before and after surgery,as well as adverse reactions were observed between the two groups. RESULTS AND CONCLUSION:Six months after operation,there was no significant difference in treatment efficacy rate between the two groups(P>0.05).At 3 and 6 months after surgery,the levels of tooth mobility,probing depth,clinical attachment loss,and bleeding index in the observation group were lower than those in the control group(P<0.05).At 6 months after surgery,the height of alveolar bone in the observation group was higher than that in the control group(P<0.05).At 3 and 6 months after surgery,the levels of transforming growth factor-β in gingival crevicular fluid in the observation group were higher than those in the control group(P<0.05).At 3 and 6 months after surgery,the levels of serine protease inhibitor and matrix metalloproteinase-3 in the observation group were lower than those in the control group(P<0.05).The results suggest that using platelet-rich fibrin+autogenous bone filling in guided tissue regeneration treatment of patients with severe alveolar bone defects can improve the periodontal microenvironment,reduce gingival tissue inflammation,promote alveolar bone tissue regeneration and repair,and reduce tooth mobility.
