Nonlinear functions are crucial points and terms in engineering problems. Actual and physical problems can be solved by solving and processing such functions. Thus, most scientists and engineers focus on solving these equations. This paper presents a novel method called the max-min method for presenting an accurate approximate analytical solution to strong nonlinear oscillators. It can solve many linear or nonlinear differential equations without the tangible restriction of sensitivity to the degree of the nonlinear term. It is also quite convenient due to the reduction in the size of calculations. The algorithm suggests a promising approach and is systematically illustrated step by step.

Intensive care unit (ICU) is important in the rehabilitation of critically ill patients. In the past decades, many patients who received aggressive treatment in ICU developed sclerosing cholangitis in multiple centers. Sclerosing cholangitis in critically ill patients (SC-CIP) is a relatively new issue. To investigate the causes, clinical manifestation, treatment, and prognosis of SC-CIP, we searched for published cases in the databases of PubMed, Highwire, and Elsevier from 2001 to 2012. Data were extracted using a standard form and retrospectively analyzed. Twelve eligible studies covering 88 patients, with 64 men and 24 women, were enrolled in this analysis. The mean age was 49.8 years. All of the patients recovered from critical illnesses, such as trauma, infection, burn, and major surgeries. High pressure positive end-expiratory pressure (PEEP, peak level at 12.8 cm H2O) was utilized for all patients, with the average duration of 36.3 d. In addition, vasopressor agents were administered in approximately 60% of SC-CIP. A rapid increase in cholestasis and irregular strictures in the intrahepatic bile ducts was observed in the following months. With an average follow-up period of 17.9 months, poor outcomes were observed in 54 patients, including 34 deaths. In conclusion, ischemic injury of the biliary tree, which may be affected by PEEP and/or vasopressor administration, affects cholangiopathic procedure. As a newly discovered type of secondary sclerosing cholangitis, SC-CIP is a severe progressive complication of patients in ICU and should be carefully monitored by clinicians.

Transcription factor networks have evolved in order to control, coordinate, and separate, the functions of distinct network modules spatially and temporally. In this review we focus on the MYC network (also known as the MAX-MLX Network), a highly conserved super-family of related basic-helix-loop-helix-zipper (bHLHZ) proteins that functions to integrate extracellular and intracellular signals and modulate global gene expression. Importantly the MYC network has been shown to be deeply involved in a broad spectrum of human and other animal cancers. Here we summarize molecular and biological properties of the network modules with emphasis on functional interactions among network members. We suggest that these network interactions serve to modulate growth and metabolism at the transcriptional level in order to balance nutrient demand with supply, to maintain growth homeostasis, and to influence cell fate. Moreover, oncogenic activation of MYC and/or loss of a MYC antagonist, results in an imbalance in the activity of the network as a whole, leading to tumor initiation, progression and maintenance.
