OBJECTIVETo evaluate the clinical effectiveness of Onodera prognostic nutrition index (OPNI) in the predictive value of nutrition risk.

METHODSIn a prospective cohort study from July 2014 to June 2015 in the Department of General Surgery of the Ninth People's Hospital of Chongqing, NRS2002 and OPNI were conducted in 200 patients undergoing gastrointestinal elective operation. OPNI was calculated with serum albumin (Alb) and peripheral lymphocyte (TLC) [OPNI=Alb(10(9)/L)+5×TLC(10(9)/L)]. By using the results of NRS2002 as the golden standard for diagnosis of nutrition risk (A NRS2002 score≥3 was deemed as nutritional risk and a nutritional care plan should be initiated. A NRS2002 score <3 was deemed as no nutritional risk), the effectiveness of OPNI was evaluated by the receiver operator characteristic(ROC) curve. The sensitivity, specificity, positive and negative predictive values, Youden indexes and area under ROC curve(AUC) of different diagnostic cut-off points of OPNI were analyzed to determine the optimal operating point (OOP). Kappa test was used to estimate the consistency of different cut-off points for OPNI with NRS2002 in defining nutrition risk.

RESULTSA total of 103 patients were of NRS2002 ≥3 group, and 97 of NRS2002 <3 group. The overall OPNI was 45.4±7.4. When OOP was 45.8, the AUC of OPNI was 0.914 (95% CI: 0.873 to 0.954); the sensitivity, specificity, Youden indexes were 85.4%, 85.6%, 0.711; the positive predictive value and negative predictive value were 85.3% and 83.7%, respectively. According to this OOP, the subjects were divided into the OPNI ≥45.8 group(n=102) and OPNI <45.8 group (n=98). Compared with OPNI ≥45.8 group, OPNI <45.8 group were older [(66.5±12.1)years vs. (57.0±15.3) years, t=-4.905, P=0.000], and had lower BMI[(20.4±3.0) kg/m(2) vs. (21.7±3.0) kg/m(2), t=3.069, P=0.002], lower albumin[(34.7±4.7)10(9)/L vs.(43.6±3.4)10(9)/L, t=15.542, P=0.000] and lower TLC[(1.0±0.5)10(9)/L vs.(1.6±0.7)10(9)/L, t=7.254, P=0.000], respectively. Kappa test indicated that when using OPNI=45.8, the diagnostic value of OPNI on nutrition risk was consistence with NRS2002(Kappa=0.691, P=0.000).

CONCLUSIONSOPNI can be used as a relatively simple and reliable method for clinical screening and assessment of nutrition risk.

This paper analysed the rhinoscope's clinical value in microsurgical treatment of intracranial aneurysms. Application of the rhinoscope in 87 patients, only 2 patients had ruptured during operation. However, 11 cases had ruptured in 94 cases without using rhinoscope, P < 0.05, they had a significant difference. By DSA follow-up review, 82 cases of used rhinoscope only 2 cases had remained the aneurysm neck, but 9 cases had the aneurysm neck in 77 cases which had not used the rhinoscope in the microsurgical treatment, P < 0.05, they also had significant difference. The application of rhinoscope in microsurgical treatment of intracranial aneurysms intraoperative, can reduce the risk of the intraoperative aneurysm rupture. It can achieve better clinical effect.

OBJECTIVETo optimize a compound prescription for treatment of liver fibrosis with an improved therapeutic effect and low toxicity.

METHODSIn rat models of liver fibrosis induced by thioacetamide (TAA), the optimized prescription was screened based on a uniform design with 2-factor 5-level table using Uniform Design 3.0 software and tested using liver content of Hyp as the screening index. To verify the efficacy of the optimized prescription, the rat models of liver fibrosis were randomized into normal control group, model group, colchicine group and optimized prescription group, and the changes of hepatic Hyp content, serum HA, ALT, AST, and ALB levels, and the pathology liver fibrosis were observed after corresponding treatments.

RESULTSThe optimized prescription, which contained 70 mg/kg glycyrrhizin and 70 mg/kg matrine, showed a significant therapeutic effect against liver fibrosis in rats (Plt;0.05), and the effect was equivalent to that of colchicine (P>0.05).

CONCLUSIONUniform design is a valuable method in prescription optimization. The optimized compound prescription of matrine and glycyrrhizin has a significant effect in inhibiting liver fibrosis.
