Thoracic perfusion of lobaplatin combined with endostar for treating malignant pleural effusions: A meta-analysis and systematic review.

INTRODUCTION: Lobaplatin is a new platinum-based cytotoxic chemotherapeutic agent. Endostar is an endogenous angiogenic inhibitor with implicated anti-tumor activity. This study was to investigate the efficacy and safety of thoracic perfusion of lobaplatin combined with endostar in the treatment of malignant pleural effusions (MPE). METHODS: We searched the databases of Pubmed, the Cochrane Library, Embase, WanFang Data, and CNKI to select the studies regarding the efficacy and safety of lobaplatin combined with endostar to treat MPE. A total of 10[3-12] randomized controlled trials with 651 patients were included. RESULTS: The objective response rate (P < .001, odds ratio = 4.08) and disease control rate (P < .001, odds ratio = 3.69) of lobaplatin combined with endostar were significantly higher than lobaplatin alone. In addition, lobaplatin combined with endostar remarkably promoted the quality of life of patients (P < .001, odds ratio = 3.93) compared with lobaplatin alone. Lobaplatin combined with endostar also promoted the quality of life of patients (P < .05, odds ratio = 2.56) compared with cisplatin combined with endostar. At the same time, the leukopenia rate (P < .05, odds ratio = .40) and the incidence of nausea and vomiting (P < .05, odds ratio = .38) of lobaplatin combined with endostar were significantly lower than that of cisplatin combined with endostar. CONCLUSIONS: The efficacy of lobaplatin combined with endostar was superior to lobaplatin alone. The safety was higher than cisplatin combined with endostar through thoracic perfusion in treating MPE, which indicated that lobaplatin combined with endostar could be the effective agent for controlling MPE.

Robot-assisted thoracoscopic surgery vs. sternotomy for thymectomy: A systematic review and meta-analysis.

Introduction: Surgeons have widely regarded sternotomy (ST) as the standard surgical method for thymectomy. Minimally invasive methods for thymectomy, including video-assisted and robot-assisted thoracoscopic surgery (RATS), have been explored. There are some studies have researched and compared the outcomes of patients after robotic and sternotomy procedure. Methods: We searched the databases of Pubmed, the Cochrane Library, Embase and selected the studies on the efficacy and safety of RATS or ST for thymectomy. Meta-analysis was performed for operation time, operation blood loss, postoperative drainage time, operative complications and hospitalization time. Results: A total of 16 cohort studies with 1,089 patients were included. Compared to ST, RATS is an appropriate alternative for thymectomy which reduced operation blood loss [standardized mean difference (SMD) = -1.82, 95% confidence interval (95% CI): (-2.64, -0.99), p = 0.000], postoperative drainage time [SMD = -2.47, 95% Cl: (-3.45, -1.48), p = 0.000], operative complications [odds ratio (OR) = 0.31, 95% Cl: (0.18, 0.51), p = 0.000] and hospitalization time [SMD = -1.62, 95% Cl: (-2.16, -1.07), p = 0.000]. Conclusions: This meta-analysis based on cohort studies shows that RATS has more advantages over ST. Therefore, RATS is a more advanced and suitable surgical method for thymectomy.

Gastrodia remodels intestinal microflora to suppress inflammation in mice with early atherosclerosis.

Atherosclsis is a critical actuator causing cardiac-cerebral vascular disease with a complicated pathogeneon, refered to the disorders of intestinal flora and persistent inflammation. Gastrodin (4-(hydroxymethyl) phenyl-ß-D- Glucopyranoside) is the most abundant glucoside extracted from the Gastrodiaelata, which is a traditional Chinese herbal medicine for cardiac-cerebral vascular disease, yet its mechanisms remain little known. In the present study, the gastrodia extract and gastrodin attenuate the lipid deposition and foam cells on the inner membrane of the inner membrane of the thoracic aorta in the early atherosclerosis mice. Blood lipid detection tips that TC and LDL-C were reduced in peripheral blood after treatment with the gastrodia extract and gastrodin. Furthermore, unordered gut microbes are remodeled in terms of bacterial diversity and abundance at family and genus level. Also, the intestinal mucosa damage and permeability were reversed, accompaniedwith the reducing of inflammatory cytokines. Our findings revealed that the functions of gastrodia extract and gastrodin in cardiac-cerebral vascular disease involved to rescued gut microbes and anti-inflammation may be the mechanismof remission lipid accumulation.

Induction of autophagy via the TLR4/NF-κB signaling pathway by astragaloside â £ contributes to the amelioration of inflammation in RAW264.7 cells.

Cigarette smoking-related lung injury is one of the most common and fatal etiologies of many respiratory diseases, for which no effective interventions are available. Astragaloside Ⅳ (ASⅣ) is an active component extracted from Astragalus membranaceus. It is prescribed as a treatment for upper respiratory tract infections. Here, we report the potential anti-inflammatory effects and mechanisms of ASⅣ on cigarette smoking extract- (CSE)-exposed RAW264.7 cells. Murine macrophages were exposed to CSE, followed by administration of ASⅣ at 25-100 µg/mL for 24 h. ASⅣ significantly rescued CSE-induced cell death by inhibition of release pro-inflammatory cytokines. We measured autophagy as an intracellular scavenger by analyzing autophagic flux using tandem mRFP-GFP-LC3 fluorescence microscopy. Following administration with ASⅣ in CSE-exposed RAW264.7 cells, there was a notable increase in autophagosomes and a range of autophagic vacuoles were generated, as seen with transmission electron microscopy. Loss of autophagy following transfection siRNA aggravated inflammatory injury and release of inflammatory cytokines. Mechanistically, ASⅣ-triggered autophagy is mediated by the TLR4/NF-κB signaling pathway to reduce inflammation. Taken together, our findings suggest that ASⅣ acts stimulates autophagy, and that ASⅣ induces autophagy by inhibiting the TLR4/NF-κB signaling pathway, contributing to alleviation of inflammation.

[Determination of tiopronin in rat plasma by HPLC following fluorescent derivatization].

A sensitive, rapid method for determining reduced tiopronin concentration in rat plasma has been developed by using a high-performance liquid chromatography (HPLC) technique in conjunction with the derivatizing agent N-(1-pyrenyl) maleimide (NPM). The analytes were separated on a Kromasil C18 column (250 mm x 4.6 mm, 5 microm) using 0.2% glacial acetic acid aqueous solution including 0.015 mol x L(-1) KH2PO4 and acetonitrile (56:44) as a mobile phase at a flow-rate of 0.8 mL x min(-1), and fluorescence detection wavelength were set at lamda(e x) = 340 nm and lamda(e m) = 375 nm, the column temperature was 30 degrees C. The calibration curve was found to be linear over a range of 0.1 - 10.0 microg x mL(-1), the limit of quantitation was 0. 1 mg x L(-1). The coefficients of the variation for the within-run and between-run precisions ranged from 5.3% to 10.8% and 7.0% to 10.8%, respectively. The percentage of absolute recovery ranged from 73.7% to 79.7%. The method was used to determine the concentration of tiopronin in rat plasma after a single intragastric administration of 25 mg x kg(-1) tiopronin to 6 healthy male Wistar rats. The pharmacokinetic process was fitted to a two-compartment model. The method has been successfully applied to the determination of tiopronin in rat plasma.
