Uniportal thoracoscopic pulmonary lobectomy in the treatment of Lung Cancer.

Objective: To investigate the clinical efficacy of uniportal thoracoscopic pulmonary lobectomy in the treatment of lung cancer.

Methods: One hundred and ten patients with lung cancer who were admitted to our hospital from February 2017 to June 2018 were enrolled and they were divided into the control group (55 patients) and observation group (55 patients) according to the random number table method. The patients in the observation group received uniportal thoracoscopic pulmonary lobectomy, and patients in the control group underwent triportal thoracoscopic pulmonary lobectomy.

Preparation and characterization of N-chitosan as a wound healing accelerator.

Chitosan is insoluble in water due to its rigid crystalline structure, which has significantly restricted its application in wound healing. The objective of this study was to synthesize a water-soluble chitosan derivative, N-succinyl-chitosan (NSC), and evaluate its ability to accelerate the wound healing process. NSC was synthesized with succinic anhydride, hydrochloric acid, and alkaline chitosan under optimized conditions, and characterized using Fourier transform infrared, proton nuclear magnetic resonance, and X-ray diffraction spectroscopy; thermal gravimetric analysis; and a solubility test.

Healing of skin wounds with a chitosan-gelatin sponge loaded with tannins and platelet-rich plasma.

A chitosan-gelatin sponge (CSGT) was prepared using a chitosan/ascorbic acid solution blend containing gelatin, followed by crosslinking with tannin acid and freeze-drying, thereby combining the chitosan sponge and gelatin sponge. The structure of the CSGT was observed by scanning electron microscopy and was shown to have uniform and abundant pores measuring about 145-240μm in size. We also characterized the sponges by infrared spectroscopy, thermogravimetric analysis, mechanical property tests, swelling behavior analysis, water retention capacity tests, antibacterial property analysis, and cytotoxicity tests.
