Abstract: Objective To explore the correlation between the levels of silent information regulator 1 (SIRT1) and forkhead box protein O3 (FOXO3) in peripheral blood mononuclear cells of patients with active pulmonary tuberculosis (APTB) and macrophage-related cytokines-inducible nitric oxide synthase (iNOS) and arginase-1 (Arg-1). Methods A total of 64 APTB patients who were treated in Yubei Hospital, the First Affiliated Hospital of Chongqing Medical University from January 2020 to December 2021 were gathered as the APTB group, 59 people with latent tuberculosis infection (LTBI) were gathered as the LTBI group, and 62 healthy people were gathered as the control group. Quantitative real-time PCR (qPCR) method was performed to measure the levels of SIRT1 mRNA and FOXO3 mRNA in peripheral blood mononuclear cells. The enzyme-linked immunosorbent assay (ELISA) was performed to measure serum iNOS and Arg-1 levels; ROC curve was used to analyze the value of SIRT1 mRNA and FOXO3 mRNA levels in the differential diagnosis of LTBI and APTB; Pearson correlation was performed to analyze the correlation of SIRT1 mRNA and FOXO3 mRNA in peripheral blood mononuclear cells of APTB patients with serum iNOS and Arg-1 levels. Results The levels of SIRT1 mRNA, FOXO3 mRNA and serum iNOS in peripheral blood mononuclear cells decreased in control group, LTBI group and APTB group, and the level of serum Arg-1 increased in turn (P<0.05). The AUCs of SIRT1 mRNA and FOXO3 mRNA in differential diagnosis of LTBI and APTB were 0.876 and 0.887, respectively, the sensitivity was 71.2% and 76.3%, and the specificity was 96.9% and 90.6% respectively. The levels of SIRT1 mRNA and FOXO3 mRNA in peripheral blood mononuclear cells of APTB patients were positively correlated (r=0.500, P<0.05), and they were positively correlated with serum iNOS and negatively correlated with serum Arg-1 (P<0.05). The SIRT1 mRNA, FOXO3 mRNA and serum iNOS in peripheral blood mononuclear cells of APTB patients after 6 months of treatment were higher than those before treatment, and serum Arg-1 was lower than before treatment (P<0.05). Conclusions The levels of SIRT1 mRNA and FOXO3 mRNA in peripheral blood mononuclear cells of APTB patients are low, and they are positively correlated with macrophage-related cytokine iNOS and negatively correlated with Arg-1.

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.

A sesquiterpene synthase (AsSS4) full-length open reading frame (ORF) cDNA was cloned from wounded stems of Aquilaria sinensis by RT-PCR method. The result showed that the ORF of AsSS4 was 1,698 bp encoding 565 amino acids. Prokaryotic expression vector pET28a-AsSS4 was constructed and transformed into E. coli BL21 (DE3) pLysS. Recombinant AsSS4 protein was obtained after induction by IPTG and SDS-PAGE analysis with a MW of 64 kD. Enzymatic reactions using farnesyl pyrophosphate showed that recombinant AsSS4 protein purified by Ni-agarose gel yielded five sesquiterpene compounds, cyclohexane, 1-ethenyl-1-methyl-2, 4-bis(1-methylethenyl)-, β-elemene, α-guaiene, α-caryophyllene and δ-guaiene. This paper reported the first cloning and functional characterization of AsSS4 gene from A. sinensis, which will establish a foundation for future studies on the molecular mechanisms of wound-induce agarwood formation in A. sinensis

Objective To investigate the effect of histone deacetylase inhibitor trichostatin A (TSA) on the chemotherapy sensibility of 5-fluorouracil (5-Fu) in colorectal cancer cell line Lovo, and to explore the possible mechanisms.Methods According to the treatment methods, the cells were divided into control group, 5-Fu group, TSA group, TSA preconditioning group and combination group (TSA+5-Fu).MTT assay was used to detect cell proliferation at 24 h, 48 h and 72 h after drugs treatment.Transwell assay was used to test cell invasion after 24 h drugs treatment.Flow cytometer was applied to observe the apoptosis after 24 h drugs treatment.The expressions of thymidylate synthase (TS) were detected by Western blot after 24 h drugs treatment.Results Compared with control group, the 5-Fu group, TSA preconditioning group and combination group had a growth inhibition to Lovo cell at 24 h, 48 h and 72 h (P < 0.05), and compared with 5-Fu group, the growth inhibition of TSA preconditioning group and combination group were distinctive at 48 h and 72 h (P < 0.05).However, the inhibition between TSA preconditioning group and combination group were no significant (P > 0.05).Interfered after 24 h, the number of cells penetrating the matrigel in control group, 5-Fu group, TSA group,TSA preconditioning group and combination group were (25.0±4.2), (16.8±2.8), (19.6± 2.5), (8.2±3.2) and (6.5±2.6), respectively (P < 0.05), and the apoptosis rates were (4.26±1.36) %, (11.66± 3.18) %, (8.57±2.69) %, (39.79±8.53) % and (45.18±10.07) %, respectively (P < 0.05).Compared with control group, the number of cells penetrating the matrigel in the experimental groups was significantly decreased, and the apoptosis rate was significantly increased (P < 0.05).Compared with 5-Fu group, the numbers of cells penetrating the matrigel in TSA preconditioning group and combination group were markedly decreased, and the apoptosis rates were markedly increased (P < 0.05), but the number of cells penetrating the matrigel and the apoptosis rate between TSA preconditioning group and combination group were not different (P > 0.05).The difference of TS expression between control group and 5-Fu group was not significant (P > 0.05).Compared with that in control group and 5-Fu group, TS expressions in TSA group, TSA preconditioning group and combination group were markedly decreased (P < 0.05), but TS expressions among the last three groups were not different (P > 0.05).Conclusion TSA can increase the chemotherapy sensibility of 5-Fu in Lovo cells, which may be dependent on reducing the TS expression.

Objective To investigate the expression of the enhancer of zeste homolog 2 (EZH2) gene and its significance in colorectal adenocarcinoma.Methods Immunohistochemistry and Western blot was used to assess the expression of EZH2 in human colorectal adenocarcinoma tissues,colorectal adenoma tissues and non-cancerous adjacent colorectal tissues.The relationships between EZH2 and each clinical pathology parameter were analyzed.Results The results of immunohistochemical trail showed that the expression rates of EZH2 in colorectal adenocarcinoma,colorectal adenoma and non-cancerous adjacent colorectal tissues were 80.56 % (87/108),62.5 % (25/40) and 5.00 % (2/40),respectively (P < 0.05).Western blot revealed that the expression level of EZH2 in colorectal adenocarcinoma tissues,colorectal adenoma tissues and non-cancerous adjacent colorectal tissues level 0.549±0.145,0.283±0.023 and 0.107±0.022,respectively.The level in colorectal adenocarcinoma tissues (0.549±0.145) and colorectal adenoma (0.283±0.023) was significantly higher than that in non-cancerous adjacent colorectal tissues (0.107±0.022).Compared with colorectal adenoma tissues,level in colorectal adenocarcinoma tissues was significantly higher.There were significant differences among the three groups (F =20.113,P < 0.05).The ratio of high expression level of EZH2 in colorectal adenocarcinoma tissues was closed related with tumorgenesis,differentiation,TNM staging and lymphatic metastsis (all P < 0.05).However,no correlation was revealed between EZH2 expression and the age,gender (both P > 0.05).Conclusion The expression of EZH2 may be associated with the tumorgenesis invasion,metastasis and progression of colorectal adenocarcinoma.
