1.Oxygen reserve index, a new method of monitoring oxygenation status: what do we need to know?
Chinese Medical Journal 2020;133(2):229-234
The oxygen reserve index (ORI) is a new technology that provides real-time,non-invasive,and continuous monitoring of patients' oxygenation status.This review aimed to discuss its clinical utility,prospect and limitations.A systematic literature search of PubMed,MEDLINE,Google Scholar,and ScienceDirect was performed with the keywords of "oxygen reserve index," "ORI," "oxygenation," "pulse oximetry," "monitoring," and "hyperoxia." Original articles,reviews,case reports,and other relevant articles were reviewed.All articles on ORI were selected.ORI can provide an early warning before saturation begins to decrease and expands the ability to monitor the human body's oxygenation status noninvasively and continuously with the combination of pulse oximetry so as to avoid unnecessary hyperoxia or unanticipated hypoxia.Although the technology is so new that it is rarely known and has not been applied to routine practices in hospitals,it shows good prospects for critical care,oxygen therapy,and intraoperative monitoring.

The concentration of 5 nucleosides, uracil, uridine, guanidine, adenine and adenosine in culture of Paecilomyces hepialid was determined by the developed method of HPLC. The HPLC method was performed on a Waters SunFire C18 (4.6 mm x 250 mm, 5 μm) column with methanol-water gradient elution as the mobile phase. The detection wavelength was 260 nm and the colunmn temperature was controlled at 30 °C. The linear range was 10.00-200.00 mg · L(-1) (r = 0.9994) for uracil, 10.10-202.00 mg · L(-1) (r = 0.9992) for uridine, 10.00-200.00 mg · L(-1) (r = 0.9991) for guanidine, 10.30-206.00 mg · L(-1) (r = 0.9992) for adenine and 10.45-209.00 mg · L(-1) (r = 0.9991) for adenosine, respectively. The RSD of precision was 0.032%, 0.035%, 0.039%, 0.049%, 0.00080%, respectively. The average recoveries of uracil, guanidine, adenine, and adenosine were 97.34%, 99.10%, 101.6%, 98.61% and 100.2% with RSD of 1.3%, 2.1%, 0.96%, 0.95%, and 1.3% respectively. The method showed high sensitivity, good selectivity, linearity and repeatability, which was suitable for the content analysis of 5 nucleosides components in P. hepialid and its extracts.

Hepatitis E, caused by hepatitis E virus (HEV) infection, usually leads to an acute clinical course, and is the most common diagnosis among cases of acute viral hepatitis. From 2008, there have been increasing reports of chronic HEV infection in immunocompromised patients such as organ transplant recipients. Without intervention with antiviral treatment, approximately 60% of HEV infections in organ transplant recipients evolve into chronic HEV infections. Of these chronic hepatitis E patients, 10% may develop liver fibrosis and progress to liver cirrhosis. This article reviews chronic HEV infection and treatment in organ transplant recipients.

Objective To evaluate retrospectively the role of 18 F-fluorodeoxyglucose (FDG) PET/CT associated with MRI in the localization of epileptogenic foci. Methods Sixty-seven patients with medically resistant epilepsy were included from 2003 to 2008. All underwent 18F-FDG PET/CT and MRI for presurgical evaluation as well as post-surgical evaluation 12 to 65 months after operation. Based on postoperative seizure occurrence, patients were divided into two groups. One group was free of seizures ( Engel classification Ⅰ, Group 1) and the other was with postoperative seizure occurrence of any type ( Engel classification Ⅱ-Ⅳ, Group 2). X2-test or Fisher's exact test was used for the statistical analysis. Results About 71.6% (48/67) patients were defined as group 1, and 19 patients were group 2 ( 11 were Engel Ⅱ , 5 were Engel Ⅲ, and 3 were Engel Ⅳ ). In Group 1, no statistically significant difference was found between concordant (45/63) and discordant findings (3/4) with regard to 18F-FDG PET/CT and MRI images (Fisher's exact test, P >0.05). For 41 patients that showed focal abnormality both on MRI and 18F-FDG PET/CT, 80.5% (33/41) were found in group 1. For 20 patients that showed focal lesions on MRI while with multi-focal or generalized abnormal metabolism on 18F-FDG PET/CT, 11 (55.0%) were in group 1 and9 (45.0%) were group 2. There was no significant difference (33/41 vs 11/20, X2 =4.34, P <0.05 ). Conclusion 18F-FDG PET/CT associated with MRI may offer more helpful information for pre-surgical evaluation and prediction of prognosis of epileptic patients.

Three human leucine-rich repeats and immunoglobulin-like domains (LRIG) genes and proteins, named LRIG1-3, has been previously characterized and it was proposed that they may act as suppressors of tumor growth. The LRIG1 protein can inhibit the growth of tumors of glial cells and the down-regulation of the LRIG1 gene may be involved in the development and progression of the tumor. Real-time reverse transcription-polymerase chain reaction (RT-PCR) is a recently developed technique for quantitative assessment of specific RNA levels. In the current study, it was demonstrated that LRIG1-3 and EGFR mRNA was detected in human pituitary adenoma cell lines and a normal pituitary sample, with differences in the expression levels. Compared to the normal pituitary samples, the expression of LRIG1-3 in HP75 cell line was lower, but the expression of EGFR in HP75 cell line was higher. The results are consistent with LRIG1-3 being tumour suppressor genes, and LRIG genes decreasing the expression of EGFR. The ratio of EGFR/LRIG1 was increased at least 13-fold in HP75 cells compared with the normal pituitary cells, which was also the case for the ratio of EGFR/LRIG2 (14-fold increase in HP75) and EGFR/LRIG3 (11-fold increase in HP75). Further studies were needed to elucidate the explicit role of LRIG genes as negative regulators of oncogenesis in human pituitary adenoma.
