Example Input: Context: To develop a method for quick identification of sun-dried and sulfur-fumigated Cimicifugae Rhizoma by Fourier transform infrared spectroscopy (FTIR).', 'The alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma were analyzed and compared by FTIR combined with second derivative infrared spectroscopy.', 'FTIR spectra showed that there were some differences in the positions of infrared absorption peaks and the relative intensities in the alcoholic and aqueous extracts of sun-dried and sulfur-fumigated Cimicifugae Rhizoma, and the second derivative IR spectra clearly enhanced the spectral resolution of their differences. FTIR spectra showed that the new absorption peaks of Cimicifugae Rhizoma appeared and a part of original absorption peaks disappeared after sulfur-fumigation in aqueous extracts, while a lot of new absorption peaks appeared and the intensities of almost all absorption peaks significantly decreased after sulfur-fumigation in alcoholic extracts. Second derivative IR spectra showed that both sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by water differed significantly from each other ranging from about 3 950 to 3 940 cm(-1), 3 850 to 3 800 cm(-1), 1 800 to 1 750 cm(-1), as well as from 1 400 to 1 350 cm(-1); Differences also existed between sun-dried and sulfur-fumigated Cimicifugae Rhizoma extracted by ethanol ranging from about 3 980 to 3 960 cm(-1), 3 850 to 3 800 cm(-1), and 1 500 to 1 460 cm(-1).
Answer: The FTIR method combined with the second derivative IR spectrum can be used to analyze and distinguish sun-dried and sulfur-fumigated Cimicifugae Rhizoma quickly and accurately. The developed method provides an efficient approach for the quality control of Chinese herbal medicines with its simplicity and strong specificity.
Example Output: Do [ Quick identification and discrimination of sun-dried and sulfur-fumigated cimicifugae rhizoma by Fourier transform infrared spectroscopy ]?

Example Input: Context: Dyschloremia is common in critically ill patients, although its impact has not been well studied. We investigated the epidemiology of dyschloremia and its associations with the incidence of acute kidney injury and other intensive care unit outcomes.', 'This is a single-center, retrospective cohort study at Mayo Clinic Hospital-Rochester. All adult patients admitted to intensive care units from January 1st, 2006, through December 30th, 2012 were included. Patients with known acute kidney injury and chronic kidney disease stage 5 before intensive care unit admission were excluded. We evaluated the association of dyschloremia with ICU outcomes, after adjustments for the effect of age, gender, Charlson comorbidity index and severity of illness score.', 'A total of 6,025 patients were enrolled in the final analysis following the implementation of eligibility criteria. From the cohort, 1,970 patients (33%) developed acute kidney injury. Of the total patients enrolled, 4,174 had a baseline serum chloride. In this group, 1,530 (37%) had hypochloremia, and 257 (6%) were hyperchloremic. The incidence of acute kidney injury was higher in hypochloremic and hyperchloremic patients compared to those with a normal serum chloride level (43% vs.30% and 34% vs. 30%, respectively; P < .001). Baseline serum chloride was lower in the acute kidney injury group vs. the non-acute kidney injury group [100 mmol/L (96-104) vs. 102 mmol/L (98-105), P < .0001]. In a multivariable logistic regression model, baseline serum chloride of ≤94 mmol/L found to be independently associated with the risk of acute kidney injury (OR 1.7, 95% CI 1.1-2.6; P = .01).
Answer: Dyschloremia is common in critically ill patients, and severe hypochloremia is independently associated with an increased risk of development of acute kidney injury.
Example Output: Does dyschloremia be a Risk Factor for the Development of Acute Kidney Injury in Critically Ill Patients?

Example Input: Context: The aim of this study was to evaluate long-term allograft salvage rates of patients with steroid refractory allograft rejection after kidney transplantation and to identify factors indicating a successful outcome.', 'Fifty patients with continuing rejection after high-dose steroids were included in the study. Baseline immunosuppression was switched from cyclosporine to tacrolimus in all patients. Twenty patients additionally received OKT3 as antirejection therapy. Patients having received a cadaveric renal transplant in 1995, excluding patients with steroid resistant rejection, were chosen as a control cohort.', 'Patient survival rates were 96% (n = 48) and 90% (n = 45) and allograft survival rates were 66% (n = 33) and 62% (n = 31) after 5 and 7 years following steroid refractory renal allograft rejection. Graft survival within the control cohort was 73% after 5 years and 69% after 7 years. Creatinine clearance increased from 20 +/- 15 ml/min/1.73 m2 at the start of tacrolimus therapy to 37 +/- 29 ml/min/1.73 m2 and to 32 +/- 26 ml/min/1.73 m2 after 5 and 7 years. OKT3 treatment predicted successful rescue therapy (p = 0.005 and p = 0.04 after 5 and 7 years).
Answer: Our data indicate a reasonable graft survival in steroid refractory renal allograft rejection using tacrolimus. OKT3 treatment in addition to tacrolimus therapy may be beneficial for long-term allograft survival.
Example Output:
Is oKT3 therapy in addition to tacrolimus associated with improved long-term function in patients with steroid refractory renal allograft rejection?
