Review Meta Analysis
NF-κB Expression and Outcomes in Solid Tumors: A Systematic Review and Meta-Analysis.
Nuclear factor-kappaB (NF-κB) is a key inflammatory transcription factor expressed frequently in tumors. Numerous studies have investigated the correlation between NF-κB expression and prognosis in solid tumors, but the conclusions are still in contradiction. Here, we conduct a meta-analysis to explore the overall association of NF-κB overexpression and survival in human solid tumors. ⋯ There is no correlation between cellular localization of NF-kB overexpression and OS of solid tumors. Among the tumor types, NF-κB was associated with worse 3 year-OS of colorectal cancer (OR = 2.70, 95% CI = 1.64-4.46, P < 0.0001), esophageal carcinoma (OR = 6.00, 95% CI = 3.29-10.94, P < 0.0001) and worse 5 year-OS of colorectal cancer (OR = 2.72, 95% CI = 1.92-3.85, P < 0.00001), esophageal carcinoma (OR = 5.96, 95% CI = 3.48-10.18, P = 0.03), and nonsmall cell lung cancer (OR = 1.69, 95% CI = 1.20-2.38, P = 0.002). Expression of NF-κB is associated with worse survival in most solid tumors irrespective of NF-κB localization.

Idiopathic pulmonary fibrosis (IPF) is a progressive disease with a poor prognosis. A number of studies reported the association between MUC5B promoter polymorphism rs35705950 and IPF, but substantial inconsistent findings were observed and the strength of association remains unclear. The aim of the study was to investigate the association between rs35705950 and IPF in different ethnic populations. ⋯ The strength of association was more remarkable in the Caucasian population than in the Asian population, and no homozygous TT genotype was detected in the Asian population in our study. Our study revealed strong association between the MUC5B promoter rs35705950 polymorphism and the risk of IPF. The strength of association between rs35705950 minor T allele and IPF susceptibility was particularly evident in the Caucasian population, and milder but still significant in the Asian population.

Randomized Controlled Trial Observational Study
Intraoperative Dexmedetomidine Promotes Postoperative Analgesia and Recovery in Patients after Abdominal Colectomy: A CONSORT-Prospective, Randomized, Controlled Clinical Trial.
Surgery-induced acute postoperative pain and stress response may lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia and recovery after abdominal colectomy surgeries. Sixty-seven patients scheduled for abdominal colectomy under general anesthesia were divided into two groups, which were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). ⋯ During the first 24 hours after surgery, PRD patients consumed less morphine in patient-controlled analgesia, and had a lower score in visual analog scale, than their controls from the PRS group. The global 40-item quality of recovery questionnaire and 9-question fatigue severity score both showed a higher recovery score from day 3 after surgery in the PRD group. Intraoperative administration of dexmedetomidine seems to promote the analgesic property of morphine-based patient-controlled analgesia, and speed recovery from surgery in patients after abdominal colectomy.

The evidence for optimal endoscopic management of bleeding gastric varices is lacking. The clinical outcome is controversial in trials comparing cyanoacrylate injection and band ligation. To help guide endoscopic decisions regarding acute gastric variceal bleeding, a meta-analysis was conducted. ⋯ The major limitation of this meta-analysis is the small number of studies/patients included. Compared with band ligation, injection cyanocrylate have an advantage in the control of acute gastric variceal bleeding, also with lower recurrence rate and rebleeding (except GOV2). The limited amount of studies included attenuates the strength of this meta-analysis; therefore, more high-quality RCTs are needed.

Randomized Controlled Trial
Double-Blind Randomized Trial of Pirfenidone in Chinese Idiopathic Pulmonary Fibrosis Patients.
Idiopathic pulmonary fibrosis (IPF) lacks effective treatment. Pirfenidone has been used to treat IPF patients. N-acetylcysteine (NAC) exerts antioxidant and antifibrotic effects on IPF cases. ⋯ In the pirfenidone group, the adverse event (AE) rate (52.63%) was higher than that in the control group (26.3%, P = 0.03). Rash was more common in the pirfenidone group (39.5% vs 13.2%, P = 0.02). Compared with placebo combined with high-dose NAC, pirfenidone combined with high-dose NAC prolonged the progression-free survival of Chinese IPF patients with mild to moderate impairment of pulmonary function. (ClinicalTrials.gov number, NCT01504334).
