At present, due to the opening and circulation of salt market, potassium iodate iodized salt, potassium iodide iodized salt, seaweed iodized salt and non-iodized salt may exist simultaneously in the edible salt market of a region, which brings new problems to the work of testing iodine content of edible salt in the laboratory. In order to carry out salt iodine detection for prevention and monitoring of iodine deficiency disorders, this paper introduces some methods which established by the author for a rapid qualitative, semi-quantitative and quantitative detection of iodized salt of different forms of iodine and non-iodized salt. And further application and discussion of the methods are described for reference of iodized salt monitoring.

Objective To explore the effectiveness of using middle-latency somatosensory evoked potentials (MLSEP) to predict the prognosis in patients with acute severe stroke. Methods MLSEP, shortlatency somatosensory evoked potentials (SLSEP), and Glasgow Coma Scale (GCS) were recorded in 70 acute severe supratentorial stroke patients within 1 week after onset. All patients were evaluated with modified Rankin Scale (mRS) and follow-up in 6 months after onset. SLSEP and MLSEP were recorded in 20 normal controls. The consistency between MLSEP, SLSEP, GCS and prognosis, as well as the prognostic authenticity of MLSEP, SLSEP, and GCS were analyzed. Results Bilateral N20, N35, and N60 exited in all normal controls. Some waves of MLSEP were absent in stroke patients, and the proportion of absent waves in ipsilateral MLSEP was higher than in contralateral MLSEP. The consistency between bilateral absence of N60 and unfavorable outcome ( Kappa = 0.828, P ＜ 0.01 ), and between bilateral absence of N60 and death ( Kappa = 0.686, P ＜ 0.01 ) was satisfactory. By using the prognostic authenticity analysis of predictors, the ipsilateral absence of N60 showed the highest sensitivity ( 100% ) for unfavorable outcome and death, which added 14.3% compared with the sensitivity of ipsilateral absence of N20 ( 85.7% ). Bilateral absence of N60 showed a high specificity of 100% for unfavorable outcome, which equaled bilateral absence of N20.However, it showed a lower specificity ( 82.9% ) for death, than bilateral absence of N20 (97.1% ).Conclusions MLSEP was able to reflect the degree of brain injury and showed higher sensitivity than SLSEP for predicting unfavorable outcomes. Therefore combined use of MLSEP and SLSEP in evaluating and predicting the outcomes in brain injuries is suggested.

Objective To study the effects of atorvastatin on expression of lysyl oxidase(LOX) in myocardial tissue of rats with diabetic cardiomyopathy (DCM) and its mechanism.Methods Thirty DCM SD rats were randomly divided into 3 groups:DCM group,treatment group (atorvastain 2 mg · kg-1 · d-1 by gastric gavage) and β-aminopropionitrile group(β-aminopropionitrile 80 mg · kg-1 · d-1 by gastric gavage),10 cases in each group.Other 10 SD rats were selected as the control group.At the end of week 8,the rats were killed for extracting the myocardial tissue RNA and protein.Expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in myocardial tissue of DCM rats were measured by RT-PCR and Western blot.Results The expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in the DCM group were significantly higher than those in the control group (P＜0.01),and compared with the DCM group,the expression of BAPN LOX,MMP-2 and NF-κB mRNA and proteins in the treatment group were significantly deceased (P＜0.01).Conclusion Atorvastatin can reverse the expression of LOX in myocardial tissue of DCM rat,and then may regulate the expression of MMP-2 and NF-κB.

Objective To explore the application of plastic pancreatic stents and/or nasal biliary drainage for choledocholithiasis patients having DSBC during Endoscopic Retrograde Cholangiopancreatography (ERCP).Methods Retrospective analysis on clinical data of 57 ERCP cases aiming at choledocholithiasis patients having DSBC from January 2010 to December 2015 has been carried out. According to the guide wire cannulation in an operation, patients are divided into three groups, i.e. plastic pancreatic stents group, nasal biliary drainage group, and plastic pancreatic stents + nasal biliary drainage group, so as to observe the success rate of operation and the occurrence rate of postoperative complications, such as pancreatitis or hyperamylasemia, as well as to compare the differences between the three groups.Results Out of the 57 patients receiving ERCP, 13 patients are in the plastic pancreatic stents group, with two successful operations (15.4%), one case of hyperamylasemia (7.7%), two cases of postoperative pancreatitis (15.4%), one case of fever (7.7%) and one case of hemorrhage (7.7%); 20 patients are in the nasal biliary drainage group, with 20 successful operations (100.0%), no occurrence of hyperamylasemia or postoperative pancreatitis or other complications including hemorrhage and fever; 24 patients are in the plastic pancreatic stents + nasal biliary drainage group, with 19 ERCP operations succeeded at the first attempt (79.2%) and 5 ERCP operations succeeded at the second try (20.8%), as well as 4 cases of hyperamylasemia (16.7%), 2 cases of hemorrhage (8.3%) , no occurrence of fever cases and postoperative pancreatitis. In comparison between the three groups, the occurrence of postoperative pancreatitis and successful rate of operation show a significant difference.Conclusion By adopting plastic pancreatic stents and/or nasal biliary drainage for patients having a dififcult selective biliary cannulation during ERCP, the success rate of operation can be improved, and the occurrence of pancreatitis can also be reduced.
