Co-Delivery of Curcumin and Paclitaxel by "Core-Shell" Targeting Amphiphilic Copolymer to Reverse Resistance in the Treatment of Ovarian Cancer.

Background: Ovarian cancer is a common malignancy in the female reproductive system with a high mortality rate. The most important reason is multidrug resistance (MDR) of cancer chemotherapy. To reduce side effects, reverse resistance and improve efficacy for the treatment of ovarian cancer, a "core-shell" polymeric nanoparticle-mediated curcumin and paclitaxel co-delivery platform was designed.

Overexpression of GP73 promotes cell invasion, migration and metastasis by inducing epithelial-mesenchymal transition in pancreatic cancer.

Pancreatic cancer is one of the most difficult clinical cases to diagnose with a very low 5-year survival rate of 5%, regardless of the advances made in both the medical and surgical treatment of the disease. One of the contributing factors for the high mortality rate seen of pancreatic cancer patients is the lack of effective chemotherapies, which is believed to be due to drug-resistance. Based on recent evidence, epithelial-mesenchymal transition (ETM) of pancreatic cancer cells has been found to be associated with the development of drug resistance and an increase in cell invasion.

[Effects of pure total flavonoids from Citrus changshan-huyou on blood lipid metabolism in hyperlipidemic rats].

To observe and investigate the effects and mechanisms of the pure total flavonoids from Citrus changshan-huyou(PTFC) on blood lipid metabolism in hyperlipidemic rats. SD rats were fed with high fat diet for 4 weeks to induce hyperlipidemic rats model, meanwhile three dosages (50, 100, 200 mg•kg ⁻¹•d ⁻¹) of PTFC were administrated intragastrically for 4 weeks respectively.After 2 weeks of modeling, their tail blood was taken and serum TC, TG, and HDL-C levels were detected by biochemical method and their body weight was measured.

[Clinical analysis of 22 cases with parotid gland duct injury].

Purpose: To discuss the early diagnosis and treatment of injury to the parotid duct.

Methods: Segmental epidural catheter was used to repair the injured parotid duct, if the broken ends of the parotid duct can't be anastomized end to end, facial vein transplantation and fascia parotideomasseterica flap were used for reconstruction.

Results: In 22 cases, one case was lost to follow-up, nineteen cases had successful reconstruction of the parotid duct with good parotid secretions.
