Shenlingcao oral liquid for patients with non-small cell lung cancer receiving adjuvant chemotherapy after radical resection: A multicenter randomized controlled trial.

BACKGROUND: Low quality of life (QoL) in patients with non-small cell lung cancer (NSCLC) receiving adjuvant chemotherapy after radical resection is a major global health issue. High-quality evidence for the effectiveness of Shenlingcao oral liquid (SOL) as a complementary treatment in this patients is lacking at present. PURPOSE: To determine whether complementary SOL treatment in NSCLC patients receiving adjuvant chemotherapy would yield greater improvements in QoL than chemotherapy alone. STUDY DESIGN: We conducted a multicenter, randomized controlled trial of stages IIA-IIIA NSCLC patients undergoing adjuvant chemotherapy in seven hospitals. METHODS: Using stratified blocks, participants were randomized in a 1:1 ratio to receive SOL combined with conventional chemotherapy or conventional chemotherapy alone. The primary outcome was the change in global QoL from baseline to the fourth chemotherapy cycle, and intention-to-treat analysis was applied with a mixed-effect model. Secondary outcomes were functional QoL, symptoms, and performance status scores at the 6-month follow-up. Missing data were handled with multiple imputation and a pattern-mixture model. RESULTS: Among 516 randomized patients, 446 (86.43%) completed the study. After the fourth chemotherapy cycle, in comparison with the control group, patients receiving SOL showed a lower reduction in mean global QoL (-2.76 vs. -14.11; mean difference [MD], 11.34; 95% confidence interval [CI], 8.28 to 14.41), greater improvement in physical function (MD, 11.61; 95% CI, 8.57 to 14.65), role function (MD, 10.15; 95% CI, 5.75 to 14.54), and emotional function (MD, 4.71; 95% CI, 1.85 to 7.57), and greater improvements in lung cancer-related symptoms (e.g., fatigue, nausea/vomiting, and appetite loss) and performance status during the 6-month follow-up period (treatment main effect, p < 0.05). CONCLUSION: SOL treatment for NSCLC patients receiving adjuvant chemotherapy can significantly improve QoL and performance status within 6 months after radical resection.

Polygonum aviculare L. extract and quercetin attenuate contraction in airway smooth muscle.

Because of the serious side effects of the currently used bronchodilators, new compounds with similar functions must be developed. We screened several herbs and found that Polygonum aviculare L. contains ingredients that inhibit the precontraction of mouse and human airway smooth muscle (ASM). High K+-induced precontraction in ASM was completely inhibited by nifedipine, a selective blocker of L-type voltage-dependent Ca2+ channels (LVDCCs). However, nifedipine only partially reduced the precontraction induced by acetylcholine chloride (ACH). Additionally, the ACH-induced precontraction was partly reduced by pyrazole-3 (Pyr3), a selective blocker of TRPC3 and stromal interaction molecule (STIM)/Orai channels. These channel-mediated currents were inhibited by the compounds present in P. aviculare extracts, suggesting that this inhibition was mediated by LVDCCs, TRPC3 and/or STIM/Orai channels. Moreover, these channel-mediated currents were inhibited by quercetin, which is present in P. aviculare extracts. Furthermore, quercetin inhibited ACH-induced precontraction in ASM. Overall, our data indicate that the ethyl acetate fraction of P. aviculare and quercetin can inhibit Ca2+-permeant LVDCCs, TRPC3 and STIM/Orai channels, which inhibits the precontraction of ASM. These findings suggest that P. aviculare could be used to develop new bronchodilators to treat obstructive lung diseases such as asthma and chronic obstructive pulmonary disease.

Clinical analysis of thoracoscopic surgery combined with intraoperative autologous blood transfusion in the treatment of traumatic hemothorax.

From January 2013 to January 2015, 19 patients of traumatic hemothorax with hemorrhagic shock were treated in our department by thoracoscopic surgery combined with autologous blood transfusion. This study retrospectively analyzed the therapeutic effect and shared our experience. The average amount of blood transfused back was 662.41 ml ± 269.15 ml. None of the patients developed transfusion reaction and were all discharged uneventfully. Thoracoscopic surgery combined with autologous blood trans- fusion is effective in the rescue of patients with progressive hemothorax and hemorrhagic shock. When corresponding indications are well managed, treatment for these patients is quicker, safer, and more effective.
