Objective To explore the relationship between high-sensitivity C-reactive protein (hs-CRP) and the occurrence of certain diseases such as coronary heart disease (CHD) and acute myocardial infarction (AMI).Methods Sixty-one CHD patients, 45 AMI patients (patients group, excluding high hs-CRP level diseases caused by other etiological factors) and 35 healthy controls (control group) were enrolled in the study. The serum level of hs-CRP and myocardial zymogram was measured in the Hitachi 7060 automatic analyzer by latex-enhance immunoturbidimetry for all subjects, and cTnI of AMI group was detected with immunofluorescence method at the same time. The difference of hs-CRP level was compared and analyzed between control group and patients group; control group before and after treatment. Moreover, the relationship between hs-CRP and myocardial zymogram as well as cTnI was analyzed.Results The level of hs-CRP was significantly higher in patients group than that in control group (P<0.01). There was statistical difference of hs-CRP level before and after treatment in control group (P<0.01). hs-CRP was positively correlative with myocardial zymogram and cTnI.Conclusion The serum level of hs-CRP is significantly elevated in CHD and AMI patients, indicating the measurement of hs-CRP contributes to auxiliary diagnosis, therapeutic effect observation, and prognosis evaluation.

Objective To investigate the effect of losartan,an angiotensin 1I type 1 receptor antagonist(ATlRA),on transforming growth factor-β1 expression in alcoholic nephropathy in rats.Methods Male adult Wistar rats were random divided into three subgroups and treated daily for 12 weeks as follows,rats were treated with normal saline[20ml/(kg·d)gavage twicely]in vehicle group,rats were treatedwith alcohol[400g/L,8g/(kg·d)gavage twieely]in alcoholic nephropathy,and rats were concomitantly treated with alcohol and Iosartan [200mg/L,ling/(kg·d),gavage]in alcohol+losartan.HE staining,Sirius red staining,electronic microscope,and immunohistochemistry were used to examine histologic changes,collagen fibers deposition,and the expression of TGF-BI.Results Compared with vehicle treated rats,alcoholic nephropathy rats showed tubular vacuolation,granular degeneration,swelling,tubulointerstitial inflammatory cell infil tration,and rarely mesangial proliferation and matrix deposition.Sirius red staining displayed a significant increase in collagen fibers in alias of glomemli,tubulointerstitium and vessels.Concomitant administration of losartan reversed all of above parameters(P<0.05).The upregulated expression of TGF-β1 proteins was significantly suppressed by losartan treatment(P<0.05).Conclusions These findings suggest that alcoholic nephropathy is characterized by the tubular granular degeneration,vacuolation,swelling,and tubulointemtitial inflammato-ry cell infiltration,and this is associated with upregulation of TGF-β1.Losartan treatment offers protection effect by downregulating TGF-β1 expression.

Objective To evaluate the efficacy and safety of mosapride in the treatment of gastroesophageal reflux disease (GERD). Methods Papers of PubMed,EMBASE,OVID,VIP Database and WANGFANG Data were searched and reviewed according to international Cochrane Collaboration.Results A total of 21 trials (1666 patients) were included.The treatment group was with mosapride and PPI,the control group was with single PPI or PPI and placebo.The Results of Meta analysis showed:for non-erosive negative reflux disease,there was no significant difference in efficacy between two groups.As for erosive esophagitis treated with mosapride (5mg):There was no significant difference in the 4-week healing rates between treatment group and control group (P =0.06).The 4-week symptom relief rate of treatment group was better than that of control group (P＜0.01).The 6-week healing rate of treatment group was better than that of control group (P＜0.01).The 6-week symptom relief rate of treatment group was better than that of control group (P＜0.01).There was no significant difference in the 8-week healing rate of esophagitis between treatment group and control group (P =0.05).The 8-week symptom relief rate of treatment group was better than that of control group (P＜0.01).For erosive esophagitis treated with mosapride 10mg,.The 8-week symptom relief rate of treatment group was better than that of control group (P=0.02).Conclusion According to the meta-analysis of these 21 trails,mosapride was safe and effective in the treatment of GERD.However due to the quality of the literatures,the above findings should be treated with caution.

Objective To observe the degree of liver su rface abnormality using high frequency probes and additional methods and to investigate the diagnostic value of semi-quatitative grading in liver fibrosis and cirrhosis. Methods One hundred and twenty-seven cases of cirrhosis (including 83 cases of hepatocelular carcinoma) confirmed by operation and pathology were enrolled in the group while 56 cases of non-cirrhotic patients with no clinical signs and negative surgical gross findings (operation for other kinds of tumors) served as the control. Five additional methods such as high frequency probes, harmonic technique, local zooming out, regulating focus and decreasing gain were used to observe the configuration and thickness of liver surface. Five-grade classification of liver surface was adopted as follows: thin and regular-grade 0; slightly thickened with increased echogenicity-grade Ⅰ; thickened like fine ripples-grade Ⅱ; significantly thickened with segmental incontinuence-grade Ⅲ; significantly thickened like waves-grade Ⅳ. Observation on configuration of the round ligament: thin, regular with the thickness ≤2 mm was considered as normal whereas thickened, irregular with increased echogenicity as abnormal. Results Of the 127 cases in the study group, 11 cases were grade 0, and grade Ⅰ 21 cases, grade Ⅱ 27 cases, grade Ⅲ 32 cases, grade Ⅳ 36 cases. In the control group there were 48 cases of grade 0 and 8 cases of grade Ⅰ-Ⅱ. The sensitivity, specificity and accuracy of liver surface detection with this method were 91.3-%, 85.7-%, 89.6-%, respectively. 75% (9/12 cases) patients with liver fibrosis and 95.5%- patients ( 64/67- cases) with cirrhosis were found with abnormality of hepatic ligaments in the study group. While only 4 cases ( 8.9-%) with abnormality appeared in the control group.Conclusions Grading of changes in liver surface might sensitively reflect their pathological changes. In addition, it would be a reliable method in the diagnosis of liver fibrosis and early stage cirrhosis as well as a semi-quatitative diagnostic tool for advancement of diffuse liver diseases.

Objective To study the pathomorphological f eatures of prostatic adenocarcinoma from biopsy. Methods Of 1147 cases of prostatic biopsy specimens,112 cases were adenocarcinoma,1030 cases benign prostatic hyperplasia and 5 cases nonspecific granulomatous prosta titis.Histological grades and the differential diagnosis between well-different iated adenocarcinoma and hyperplasia were conducted.Immunohistochemical analysis (34?E12) were done in some cases. Results 112 cases of adenocarcinoma were diagnosed according to the architectural changes, cytologic al atypia and invasion. 23 cases(20.5%)were of well-differentiated carcinoma ,38 cases(33.9%)moderately-differentiated carcinoma and 51 cases(45.5%) po or-differentiated carcinoma. 21 cases(18.8%) were of low grade prostatic intrae pithelial neoplasia(PIN Ⅰ)and 75 cases(67.0%)of high grade PIN(PIN Ⅲ) were found with in tumor tissue.With immunohistochemical stain,98 in 102 cases of BP H were positive reactive for 34?E12 in the basal layer,while 36 of 40 cases of prostatic adenocarcinoma were negative. Conclusions Ro utine pathological morphological features,combined with immunohistochemical test s is valuable for the pathological diagnosis of prostatic adenocarcinoma.

Drug clinical trial is an important link in the chain of new drug research and development. The results of drug discovery and development directly depend on the extent of standardization of clinical trials. Therefore, improving the quality of drug clinical trials is of great importance, and drug clinical trial institutions play a crucial role in the quality management of drug clinical trials. After years of development, the overall level of drug clinical trials has advanced rapidly in China, and a large number of clinical trials of traditional Chinese medicine have also been carried out. However, there is still a big gap between our country and developed countries. Therefore, for the construction and management of Chinese drug clinical trial institutions, there is still a long way to go. This study aims to analyze the current development of drug clinical trial institutions in China and explore the existing problems from three aspects, including current situations of institutional organization and management, regional and professional distributions, and quality control. And some suggestions are put forward finally, including support of traditional Chinese medicine, introduction of drug-risk management system, and construction of information management.

Objective To explore the relationship of urinary iodine level between 8-10 year-old children and adults under the same living conditions in coastal and mountain areas in Fujian Province.Methods Representative coastal and mountainous rural areas (Xindian Town Xiang'an District Xiamen City and Yongfu Town Zhangping District Longyan City) were selected as survey sites.Morning fasting urine samples from local 8-10 year-old children and their parents and a random urine sample in the morning from these children were collected.Urinary iodine was determined using the arsenic cerium catalytic spectrophotometric method (WS/T 107-2006).Results The median urinary iodine of fasting urine samples which were collected from 147 8-10 year-old children in coastal rural areas (71 boys and 76 girls) was 163.5 μg/L (boys 161.0 μg/L,girls 170.9 μg/L),and the median urinary iodine of random urine samples was 190.8 μg/L (boys 208.7 μg/L,girls 177.0 μg/L),and the difference was not statistically significant between boys and girls (Z =-0.376,-0.678,all P ＞ 0.05).The median urinary iodine of fasting urine samples which were collected from 116 8-10 year-old children in mountain rural areas (66 boys and 50 girls) was 171.8 μg/L (boys 169.5 μg/L,girls 173.8 μg/L),and the median urinary iodine of random urine samples was 210.8 μg/L (boys 233.2 μg/L,girls 203.4 μg/L),and the difference was not statistically significant between boys and girls (Z =-0.413,-0.881,all P ＞ 0.05).The median urinary iodine of random urine samples which were collected from 8-10 year-old children in mountain rural areas was significantly higher than that of the morning fasting urine samples (Z =-2.789,P ＜ 0.05).The median urinary iodine of children's fathers in coastal rural areas was 177.0 μg/L,and the median urinary iodine of their mothers was 181.7 μg/L.There was no significant difference between coastal rural children and their parents (Z =-0.387,-0.658,all P ＞ 0.05),and there was also no significant difference between fathers and mothers (Z =-0.014,P ＞ 0.05).The median urinary iodine of children's fathers in mountain rural areas was 227.3 μg/L,and the median urinary iodine of their mothers was 237.4 μg/L There was a significant difference between mountain rural children and their parents (Z =-4.176,-4.373,all P ＜ 0.05),and there was no significant difference between fathers and mothers (Z =-0.291,P ＞ 0.05).Conclusions Urinary iodine level of school-age children does not reflect the actual urinary iodine level of adults.There is a difference between urinary iodine level of random urine sample and morning fasting urine sample.Attention should be paid to this difference when monitoring iodine nutrition in population.

Objective To summarize the experience of nursing cancer patients with Wernicke encephalopathy (WE) after gastrointestinal surgery. Method The clinical data of 6 patients with WE after gastrointestinal surgery in our hospital from January 2005 to June 2015 were retrospectively analyzed to summarize the nursing strategies. Results All the 6 patients showed mental changes of different types, 5 patients developed with ocular manifestations and one patient with ataxia. Only one patient showed the classic triad of the disease at clinical presentation. All the 6 patients had characteristic manifestations on cranial MRI and received thiamine (vitamin B1) at diagnosis. Four patients were completely recovered and 2 were partially recovered. Conclusion Timely sufficient thiamine supplementation during the perioperative period is the key to prevent and treat WE in the patients with gastrointestinal cancer. Careful observation of the patients′ mental state and the effective nursing for the special classic triad of the disease are critical for a better prognosis.

Objective To explore the optimal method of qualitative and quantitative assessment of retinal neovascularization(RNV),choroidal neovascularization(CNV) and leakage from CNV. Methods Thirteen mice were randomly divided into RNV assessment group(n=7)and CNV assessment group(n=6).For RNV assessment, 3 mice were served as normal controls,and the other 4 were made into models of retinopathy of prematurity(ROP).At postnatal d16,mice in normal control group and 3 ROP model mice received intraocular injection with FITC labeled or unlabeled antibody and were sacrificed 12 h later.The retinas were flat mounted(FITC labeled antibody) or incubated with secondary antibody(unlabeled antibody) and then flat mounted.The other ROP model mouse was served as blank control.For assessment of CNV and leakage from CNV,6 mice(12 eyes) were induced into models of CNV,and were randomly divided into two groups.Seven and 14d after model establishment,mice were intraocularly injected with unlabeled antibody,and fluorescein sodium were intraperitoneally injected 12 h later.The area of CNV and that of CNV leakage were calculated. ResultsRetinas from eyes injected with FITC labeled antibody exhibited good resolution of ultrastructure of RNV,while retinas from eyes injected with unlabeled antibody showed selective staining of RNV with no background,greatly facilitating identification and quantification of RNV.Merging images of stained CNV with images of fluorescein sodium leakage from CNV revealed double labeled CNV surrounded by fluorescein that had leaked into surrounding tissues.The mean area of CNV and its leakage of d14 were significantly different from those of d 7(P
