A self-assembled fluorescent nanoprobe recognized by FA1 site for specifically selecting HSA: Its applications in hemin detection, cell imaging and fluorescent tracing drug delivery.

As naturally essential biomacromolecule, HSA has become diagnostic indicators for various diseases and universal carriers for anticancer drug delivery, therefore, fluorescence detection and labeling for HSA possess significant application value in the biomedical field. In this paper, hydrazide Schiff base fluorescent probe NDQC was designed and synthesized, which self-assembled into nanoparticles in aqueous solution system and demonstrated excellent selectivity and sensitivity towards HSA. Through displacement assay and molecular docking simulation, the binding of NDQC with HSA in FA1 site was demonstrated, thereby no obvious fluorescence signal presented for homologous protein BSA due to their structural differences in binding site.

Ghrelin promotes neural differentiation of adipose tissue-derived mesenchymal stem cell via AKT/mTOR and β-catenin signaling pathways.

Adipose tissue-derived mesenchymal stem cells (ADSCs) are multipotent cells that can differentiate into various cell types. This study aimed to investigate the effect of ghrelin on the neural differentiation of rat ADSCs and underlying molecular mechanisms. Rat ADSCs were isolated and third-passage ADSCs were used in this study.

[Relationship of Human Papillomavirus Subtypes and Multiple Infection with Different Cervical Precancerous Diseases in Sichuan Province].

Objective: To investigate the relationship of human papillomavirus (HPV) subtypes and multiple infections with different cervical precancerous diseases.

Methods: Retrospective study was done to review 1 226 patients with different cervical lesions who were pathologically diagnosed and scanned for HPV 23 subtypes with positive results from June 2006 to May 2012. These patients were divided into the following groups, chronic cervicitis, cervical condyloma, cervical intraepithelium neoplasia grade I (CIN I), grade II (CIN II), grade III (CINIII).

[Early human papillomavirus testing predicts residual/recurrent disease after LEEP risk factors for predicting residual disease in high-grade squamous cervical intraepithelial neoplasia following LEEP conization].

Objective: To explore the risk factors for residual/recurrent disease of cervical intraepithelial neoplasia (CIN) 2 or worse after loop electrosurgical excision procedure (LEEP) and the timing point for postoperative follow-up.

Methods: 428 patients with CIN 2 or CIN 3 who were treated with LEEP were retrospectively reviewed. Postoperative follow-up was performed by Pap smear and human papillomavirus (HPV) hybrid capture 2 (HC2) testing.

[Expression and clinical significances of c-myb and Bax proteins in endometrial carcinoma].

Objective: To study the expressions of c-myb and Bax proteins and their relationships with clinic-pathological characteristics in endometrial carcinoma.

Methods: The expressions of c-myb and Bax protein were detected by immunohistochemistry in 42 normal endometrial tissues and 68 endometrial carcinoma tissues. Apoptosis index was detected by TUNEL technique.

Caveolin-1 plays a key role in the oleanolic acid-induced apoptosis of HL-60 cells.

Our previous study found that caveolin-1 (CAV-1) protein expression is upregulated during oleanolic acid (OA)-induced inhibition of proliferation and promotion of apoptosis in HL-60 cells. CAV-1 is the main structural protein component of caveolae, playing important roles in tumorigenesis and tumor development. It has been shown that cav-1 expression is lower in leukemia cancer cell lines SUP-B15, HL-60, THP-1 and K562 and in chronic lymphocytic leukemia primary (CLP) cells when compared with normal white blood cells, with the lowest cav-1 expression level found in HL-60 cells.

Adipose-derived stem cells promote peripheral nerve repair.

Introduction: Recent evidence suggests that the implantation of bone marrow-derived mesenchymal stem cells improves peripheral nerve regeneration. In this study we aimed to investigate whether adipose-derived stem cells (ADSCs) can be used for peripheral nerve repair.

Material And Methods: In a rat model, nerve regeneration was evaluated across a 15 mm lesion in the sciatic nerve by using an acellular nerve injected with allogenic ADSCs.
