Objective To analyse the role of AEEG and MRI in diagnosis of epilepsy on its primary epileptic focus and pathologic lesions. Methods We reviewed the results of sixty epileptic patients on routine EEG, twenty-four hour active EEG(AEEG),CT scanning and MRI examinations. The relationship between epileptic discharges of AEEG and lesions of MRI was analyzed by using ? 2 test. Results AEEG showed a higher sensitivity in finding epileptic focus in 80% patients, as compared with the rate of 32% in routine EEG. The sensitivity on finding the cerebral lesion related to the epileptic focus by using MRI was 60%, as compared with the rate of 33% in CT scanning. There was a correlative relationship between the AEEG discharge foci and the lesions found by MRI( P

OBJECTIVEOvertraining is a serious problem in sports, assessed by comprehensive multi-index evaluation, but so far there is still no sensitive, specific monitoring indicator or simple evaluation method to evaluate it. This research established a method for detecting plasma cell free DNA (cfDNA) of rats by real time PCR and discuss edits significance: a new molecular marker of overtraining?

METHODSTwelve male SD rats were randomly divided into control group and overtraining group. The overtraining group rats were undertaken overtraining on a motor-driven treadmill for 5 weeks, while the control group rats kept quiescent. All the rats were drawn blood at pre-and after-5 weeks to detect plasma levels of cfDNA, testosterone (T) and corticosterone (Cort) as well as peroxidation/antioxidation parameters (T-AOC, MDA, SOD, GSH-Px) and creatin kinase (CK).

RESULTS(1) Plasma cfDNA of rat was detected specifically by our real time PCR. (2) Compared with control group rats, the plasma cfDNA of overtraining rats increased obviously (about 5.43 fold). (3) Plasma cfDNA was related to plasma T, Cort, T/C ratio and MDA (correlation coefficent were -0.729, 0.854, -0.655 and 0.720, respectively) rather than plasma T-AOC, GSH-Px, SOD and CK.

CONCLUSION(1) A real time PCR method was established successfully to determine plasma cfDNA of rat. (2) A remarkable raises of plasma levels of cfDNA were found in overtraining rats which were associated with T, Cort and T/C, suggested that plasma cfDNA might be a new molecular marker of overtraining. (3) The increase of plasma cfDNA of overtraining rat might correlate with enhanced oxidative stress induced by overtraining instead of muscle damage.

ObjectiveTo investigate the selective mechanism of dehydroepiandrosterone (DHEA)for osteoblast via ERβ. Methods High expression of ERβ in hMG63-ERβ group ( infected with pWPTERβ), gene silencing of ERβ in hMG63-shERβ group (infected with pLVTHM-GFP/ERβ-shRNA) and hMG,63 group (control) were cultured and treated with 1 × 10-7 mol/L DHEA, with or without U0126 and etoposide. The proliferation and apoptosis of hMG63 were evaluated by flow cytometry. The mRNA level of estrogen receptor subtype was detected by reverse transcription-PCR. ResultsThe expression of ERβ in hMG63-ERβ group and hMG63-shERβ group were increased 7. 39 times and decreased 17％ compared with that in hMG63 group (control). DHEA could increase ERβ expression in hMG63 in each group, however, it did not influence the expression of ERα mRNA. When the level of ERβ was high, DHEA could accelerate the proliferation [proliferation index were ( 81.6 ± 7.6) ％ in hMG,63-ERβ, ( 75.0 ± 5.3 ) ％ in hMG63, P ＜ 0. 05]and inhibit the apoptosis [apoptosis rate were ( 12.2 ± 1.6) ％ in hMG63-ERβ, ( 14. 6 ± 1.5 ) ％in hMG63, P ＜0. 0 1], which was blocked by U0126 [proliferation index were (33. 2 ± 2. 0)％ in hMG63-ERβ, (41.2 ± 2. 4) ％ in hMG63, apoptosis rate were (40. 5 ± 4. 3 ) ％ in hMG63-ERβ, (43.3 ± 4. 1 ) ％in hMG63, all P ＜0. 05]. When the expression of ERβ was silenced, DHEA could not inhibit the apoptosis of hMG63 anymore. ConclusionDHEA selectively act on osteoblasts via the dominant expression of ERβ.

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.

Hypoxia-inducible factor-1 (HIF-1) is a key transcription factor on hypoxia responses in mammalian tissues. HIF-1 plays as a positive factor in solid tumor and leads to hypoxia-driven responses that enhance its downstream gene expression for tumor growth and survival. LXY6099 was obtained by the structural modification and optimization of manassantin A (MA) as a high potent HIF-1 inhibitor. Antitumor activity of LXY6099 was observed in this study. LXY6099 with an IC50 value of 2.46 x 10(-10) mol x L(-1) showed more sensitive inhibition activity to HIF-1 than that of MA detected by reporter gene assay (> 100 folds). It showed strong inhibition on the growth of human solid tumor cell lines. Furthermore, LXY6099 exhibited significant antitumor activity against established human tumor xenografts in nu/nu mice with treatment of MX-1 breast cancer. Thus, LXY6099 as a novel HIF-1 inhibitor could be further developed into anti-cancer agents.
