Five diarylpentanol derivatives including two new compounds stellerasme A (1), stellerasme B (2) were isolated from the aerial parts ofStelleropsis tianschanica. Their structures were elucidated by various spectroscopic techniques (UV, IR, MS, CD, 1D and 2D NMR). All compounds were evaluated for their cytotoxicity activity against HeLa and KB cell lines, and compound1showed selective activities against HeLa cell line with an IC50value of 7.4 μM.

Conclusions: The long-term quality of life of adolescents with chronic rhinosinusitis improved significantly after functional endoscopic sinus surgery (FESS), and endoscopic sinus surgery showed certain benefits for adolescent patients. The selection of appropriate patients may further improve the surgical outcomes and quality of life. Objective: To analyze the long-term quality of life in adolescents (12-18 years) with chronic rhinosinusitis after endoscopic sinus surgery, and to evaluate the value of endoscopic sinus surgery in adolescent patients. Methods: From 2003 to 2008, 729 adolescents with chronic sinusitis underwent endoscopic sinus surgery in our department; 270 of these patients were included in the study. Their quality of life was assessed before and within 3-8 years after the surgery using the SNOT-20 scale and was compared with that of healthy individuals of the same age. Results: The SNOT-20-based assessment showed that the overall quality of life differed significantly before and after surgery ( p = 0.000) and that some symptoms (dizziness, sense of facial oppression, sleep difficulty, embarrassment, and fatigue) had no significant differences before and after surgery ( p > 0.05). Preoperative and postoperative symptoms (dizziness, sense of facial oppression, sleep difficulty, embarrassment, and fatigue) showed no significant differences between the healthy population and treated patients ( p > 0.05).

Objective. To explore the effect of high-quality nursing based on comprehensive nursing on postoperative quality of life and satisfaction of patients with malignant glioma. Methods. From September 2017 to May 2020, 86 patients with malignant glioma treated in our hospital were recruited and assigned (1 : 1) to receive either comprehensive nursing (comprehensive group) or high-quality nursing plus comprehensive nursing (high-quality group). Outcome measures included preoperative and postoperative self-rating anxiety scale (SAS) scores, self-rating depression scale (SDS) scores, quality of life, and nursing satisfaction. Results. High-quality nursing plus comprehensive nursing was associated with significantly lower SAS and SDS scores versus comprehensive nursing alone (P < 0.05). Patients receiving high-quality nursing plus comprehensive nursing showed higher quality of life scores versus those only given comprehensive nursing (P < 0.05). High-quality nursing plus comprehensive nursing resulted in higher nursing satisfaction of the patients versus comprehensive nursing alone (P < 0.05). Conclusion. High-quality nursing can relieve the negative emotions of patients with malignant glioma and significantly enhance their quality of life, thereby improving the nursing satisfaction of patients with nursing, so it is worthy of clinical application.

A new bis-γ-pyrone polypropionate compound onchidione II (1), together with three known compounds, was isolated from a marine pulmonate mollusc Onchidium struma, collected at Hainan Island of China. The structure of new compound was determined by extensive spectroscopic analyses including IR, 1D and 2D NMR techniques, and chemical methods. Compounds 1–4 were evaluated for their cytotoxicity against human tumor cell lines HepG-2, A549, and MCF-2. The results showed that compounds 1 and 2 were moderate cytotoxic against HepG-2, A549, and MCF-2 cell lines, with IC50 values from 13.2 to 22.4 μM. [ABSTRACT FROM AUTHOR]

Two new steroidal glycosides ponasteroside C (1) and ponasteroside D (2) were isolated from the aerial parts ofLepidogrammitis drymoglossoides. Their structures were elucidated by various spectroscopic techniques (IR, HRESIMS, 1D and 2D NMR). All compounds were evaluated for their cytotoxicity against HeLa and HCT-8 cell lines, and compounds1and2showed mild activity against all the test cell lines. [ABSTRACT FROM PUBLISHER]
