Osteoporosis, characterized by low bone mass and high fracture risk, challenges orthopedic implant design. Conventional 3D-printed Ti6Al4V scaffolds are mechanically robust but suffer from poor bone regeneration in osteoporotic patients due to stress shielding and cellular senescence. In this study, a functionalized 3D-printed Ti6Al4V "Cell Climbing Frame" is developed, aiming to adapt to the mechanical microenvironment of osteoporosis, effectively recruit and support the adhesion and growth of autologous bone marrow mesenchymal stem cells (BMSCs), while rejuvenating senescent cells for improved bone regeneration.

There are debates on the management of immature ovarian teratoma and its recurrence. This study aimed to report the incidence of pelvic masses after surgery for immature ovarian teratoma and to identify prognostic factors of disease-free survival after surgery, discussing aspects of primary treatment and postoperative management. Data on the diagnosis and treatment of patients with immature teratomas were collected.

A total of 9 patients with histopathologically confirmed endometrial cancer in young females with PCOS at the West China Second Hospital of Sichuan University between December 2007 and September 2013 were included. The clinicopathological characteristics of the patients were analyzed.

MicroRNAs (miRNAs/miRs) have been demonstrated to serve important functions in the pathogenesis of EOC. However, the function of miR-545 in EOC remains unknown.

Objective: To determine the expression of miR-130a in patients with epithelial ovarian cancer and its association with platinum resistance.
Methods: 32 patients with platinum resistance and 30 patients without platinum resistance were recruited in this study. Real-time PCR was performed to detect the expression of miR-130a in the serum samples of the patients.
Chemoresistance remains a major obstacle to effective treatment in patients with ovarian cancer, and recently increasing evidences suggest that miRNAs are involved in drug-resistance. In this study, we investigated the role of miRNAs in regulating cisplatin resistance in ovarian cancer cell line and analyzed their possible mechanisms. We profiled miRNAs differentially expressed in cisplatin-resistant human ovarian cancer cell line A2780/DDP compared with parental A2780 cells using microarray.

Objective: To determine the regulatory effects and associated mechanisms of miR-130a on cisplatin resistance in ovarian cancer A2780 cell lines (including cisplatin sensitive A2780s and its resistant A2780/DDP cells).
Methods: A2780s and A2780/DDP cells were divided into four groups, and treated with lipo2000 (Lip), miR-negative (miR-NC) control, miR-130a-mimics (miR-130a-M increasing the expression of miR-130a and the agent), and miR-130a-inhibitor (miR-130a-I downregulating miR-130a expression), respectively. The proliferation of cells and their sensitivity to cisplatin were detected by MTT assay.
Objective: To analyze the clinic-pathological characteristics of women with cervical cancers in southwestern China and discuss the features and prognosis of young patients.
Methods: A retrospective study was performed, which consisted of 1,543 patients diagnosed with cervical cancer and underwent treatment at West China Second University Hospital between November 2005 and December 2010. Among them, 154 young patients with surgical procedures between November 2005 and December 2008 were selected for a 5-year follow-up and prognostic analysis.
microRNAs (miRNAs) are short non-coding RNA molecules which are involved in the regulation of various biological processes. Drug resistance has become a major obstacle to successful chemotherapy of ovarian cancer. The aim of this study was to investigate microRNA expression profiles in cisplatin-resistant ovarian cancer cells and the role of miR-130a in regulating drug resistance.

Objective: To determine the expression of miR-130a in cisplatin resistant cell lines of ovarian cancer and its impact on cisplatin resistance.
Methods: Cisplatin resistant ovarian cancer cell lines were established by stepwise selection with gradual increase of cisplatin. MTT assay was applied to indentify the cisplatin resistant cell lines and determine their resistance index.

Objective: To evaluate the inhibitory effect of artemisnin on surgically induced endometriosis in rat model and the possible mechanism related to cellular apoptosis and microvascular angiogenesis.
Methods: Surgically induced endometriosis model was established with female rats, and then the rats were divided into four groups: high dose artemisinin [300 mg/(kg x d)), low dose artemisinin [150 mg/(kg x d)], danazol [160 mg/(kg x d)] and solvent control group After daily administration of the above agents for 4 weeks, the rats were sacrificed, then the implant size of ectopic endometrium was measured and appotosis index (AI), Bcl-2 and MVD in ectopic endometrium were evaluated with S-P immunohistochemistry.
Results: Compared with solvent control, both artemisinin (high and low quality) and danazol decrease the size of implants significantly (P < 0.
