The microRNA-34 Family and Its Functional Role in Lung Cancer.

Lung cancer is one of the most common malignant tumors in humans and the leading cause of cancer-related deaths worldwide. The microRNA-34 (miR-34) family is dysregulated in various human cancers and is an important family of tumor suppressor genes among microRNAs. The miR-34 family is downregulated in lung cancer.

Methods: Randomized controlled trials of neoadjuvant immunotherapy in treating patients with NSCLC were comprehensively retrieved from electronic databases, eligible studies, previous systematic reviews and meta-analyses, guidelines, and conference abstracts. The meta-analysis was performed by the Stata/SE 12.

Perivascular epithelioid cell tumor of the lung: A case report and literature review.

The perivascular epithelioid cell tumor (PEComa) is a rare tumor of interstitial origin characterized by several immunological and muscle cell markers. The clear cell sugar tumor (CCST) of the lung is a type of PEComa defined by thin cell walls and high levels of glycogen in the cytoplasm. We herein reported the case of a 48-year-old male with a recurrence of lung CCST.

Effectiveness and Safety of Acupuncture for the Treatment of Alzheimer's Disease: A Systematic Review and Meta-Analysis.

The effects of acupuncture on Alzheimer's disease (AD) outcomes remain controversial. The aim of this review was to evaluate the effectiveness and safety of acupuncture for the treatment of AD. PubMed, Embase, Web of Science, the Cochrane Central Register of Controlled Trials, Chinese BioMedical Literature Database, VIP Database for Chinese Technical Periodicals, China National Knowledge Infrastructure, and Wanfang Data were searched to identify relevant randomized controlled trials from inception to January 19, 2019.

α1-Blockers and 5α-Reductase Inhibitors Are the Most Recommended Drugs in Treating Benign Prostatic Hyperplasia: An Evidence-Based Evaluation of Clinical Practice Guidelines.

Objective: To systematically evaluate the quality of clinical practice guidelines (CPG) for medically treating benign prostatic hyperplasia (BPH), and to compare the context of recommendations in order to provide references for clinical application.

Methods: We searched databases of National Guideline Clearinghouse (NGC), Guidelines International Network (GIN), National Institute for Health and Clinical Excellence (NICE), Scottish Intercollegiate Guidelines Network (SIGN) and World Health Organization (WHO), PubMed, Embase, CNKI, VIP, WanFang Data, CBM, and Medlive from their establishment to October 13, 2019, to collect evidence-based guidelines and/or consensus on BPH. Method quality of included guidelines was assessed according to the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument, and differences and similarities among recommendations were compared.

The methodology for developing nursing clinical practice guidelines over recent decades in China: A critical appraisal using AGREE II.

Aim: To appraise the quality of current nursing clinical practice guidelines (N-CPGs) in China and explore the methodology for N-CPGs development.

Background: Implementation of quality improvement projects based on N-CPGs has becoming an hot topic for nursing with proliferation in the number of N-CPGs in China in recent years. The methodology for developing N-CPGs is worthy of exploration.

[Alkaloids from Macleaya cordata and their cytotoxicity assay].

Objective: To study the alkaloids of Macleaya cordata and their anti-tumor activities.

Method: Alcohol and liquid-liquid extraction were used methods were used to extract the alkaloids constituents, and silica gel, reverse-phase octadecylsilyl (ODS), sephadex LH-20 chromatographic methods and HPLC were applied to isolate and purify compounds. MS, NMR spectroscopic methods were used to determine their structures.

Two new quercetin glycoside derivatives from the fruits of Gardenia jasminoides var. radicans.

Two new quercetin glycoside derivatives named quercetin-3-O-[2-O-trans-caffeoyl-α-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside] (1) and quercetin-3-O-[2-O-trans-caffeoyl-β-L-rhamnopyranosyl-(1 → 6)-β-D-glucopyranoside] (2) along with three known flavonoids, 5-hydroxy-6,7,3',4',5'-pentamethoxyflavone (3), 5,7-dihydroxy-8-methoxyflavone (4) and kaempferol 3-O-β-D-glucopyranoside (5), were isolated from the fruits of Gardenia jasminoides var. radicans. The structures of the new compounds were determined by means of extensive spectroscopic analysis (1D, 2D NMR and HR-ESI-MS), glycoside hydrolysis and sugar HPLC analysis after derivatisation.

[Chemical constituents of flavonoids and their glycosides in Melastoma dodecandrum].

The chemical constituents of 95% ethanol extract of Melastoma dodecandrum were isolated and purified by chromatography on silica gel, Sephadex LH-20, and HPLC, to obtain thirteen compounds eventually. On the basis of their physico-chemical properties and spectroscopic data, these compounds were identified as quercetin (1), quercetin-3-O-β-D-glucopyranoside (2), quercetin-3-O-(6"-O-p-coumaroyl) -β-D-glucopyranoside (3), kaempferol (4), kaempferol-3-O-β-D-glucopyranoside (5), kaempferol-3-O- [2",6"-di-O-(E)-coumaroyl]-β-D-glucopyra-noside (6), luteolin (7), luteolin-7-O-(6"-p-coumaroyl) -β-D-glucopyranoside (8), apigenin (9), apigenin-7-(6"-acetyl-glucopyranoside) (10) , naringenin (11), isovitexin (12), and epicatechin-[8,7-e] -4β-(4-hydroxyphenyl)-3,4-dyhydroxyl-2(3H)-pyranone (13).
