Objective To investigate the relationship between angiotensin 1-converting enzyme(ACE)inserting/defaulting(I/D)gene polymorphisms and the carotid intima-media thickness(CCA-IMT)in patients with type 2 diabetes(T2DM).Methods The polymorphisms of ACE(I/D)was determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)method and the CCA-IMT was assessed using non-invasive high resolution B-mode ultrasonography in 120 T2DM in Han's population of Dongguan city.The data were analyzed by Logistic regression to explore the independent and significant risk factors for CCA-IMT increase in type 2 diabetic patients.Results The DD genotype were significantly more common in diabetic patients with CCA-IMT increase than in those without it(F=10.164,P=0.006);Logistic regression analysis showed that DD genotype,age,male gender and essential hypertension contributed significantly to the CCA-IMT increase in type 2 diabetic patients(OR=3.689,1.054,1.562,respectively,P

Biological monitoring is one of methods of water environment monitoring. By using the reaction of biological individual,population and community to environmental pollution,biomonitoring can expound the pollution state,provide monitoring data for the environmental quality assessment. The sensitivity,bio-concentration,long-term and comprehensive characteristics are advantages of biomonitoring. This paper summarized the methods of the biomonitoring used in practise,including biotic index,toxicity test,polyurethane foam unit,simultaneous determination,ecotoxicogenomics and involved single cell algae,protozoana,benthic organisms,amphibian. The shortages of the monitoring method also exist,for example,the regional limitation.

ObjectiveTo investigate the clinical features of acute myocardial infarction in CAPD patients.MethodsCompare the clinical and laboratory data of 39 patients with CAPD and AMI for the first time (PD group),including clinical symptoms,signs,electrocardiogram changes,myocardial enzyme changes and in hospital mortality,with those of 50 patients without renal insufficient but with AMI for the first time (C group).Diagnosis of AMI was made in hospital.ResultsCompared to C group, the symptoms presented at first in PD group were more atypical and the patients went to see doctor more lately after AMI.Atypical electrocardiogram changes were more in PD group than in C group (61.5% vs 26.0%,P

Purpose To investigate the clinicopathologic features, diagnosis and differential diagnosis of primary gastric inflammatory myofibroblastic tumor ( IMT) . Methods Four cases of gastric IMTs were studied by clinicopathologic analysis, immunohistochemistry and in situ hybridization, and the related literature was reviewed. Results In four cases there are two males and two females, age range from 21 to 51 years old, and tumor size ranged from 1. 5 to 6. 5 cm in the greatest dimension. Histologically, these tumors were composed of varied spindle cells and chronic inflammatory cells, in a myxoid or hyalinized stroma. Occasionally, there were calcifica-tion and ossification areas. Most of the spindle cells had bland appearance and a minority of the tumor cells showed mild atypia. One to two mitotic figures were recognized in 10 high power fields ( HPFs) in 1 to 2 patients. Smooth muscle actin staining was observed in all tumors and ALK staining observed in two tumors. One tumor focally expressed CD34. S-100, desmin, CD68, CD117 and DOG1 was negative in all IMTs. The patients were followed up from 24 to 66 months, and none of them had tumor relapsed or metastasis. Conclu-sions Primary gastric IMTs have an intermediate behavior, and a few cases have malignant potential. It should be distinguished from other spindle cell lesions similar to IMT.

Objective To understand the direct medical expense for surgical patients with splenomegalic advanced schisto?somiasis and its influencing factors,so as to provide evidences for relevant departments to improve the rescue strategy of ad?vanced schistosomiasis. Methods The data about the expenses of patients with splenomegalic advanced schistosomiasis hospi?talized in Xiangyue Hospital affiliated to Hunan Institute of Schistosomiasis Control from January 2010 to August 2014 were col?lected,the hospitalization expense and hospital stays of the patients were analyzed,and the factors influencing the hospital ex?penses were analyzed by the univariate and multi?factor analyses. Results From January 2010 to August 2014,totally 249 cas?es were hospitalized in the hospital,their average hospital stays and hospital expenses were 28.92 d and 18 896.13 Yuan,and both of them were increased year by year. Among all the kinds of expenses,the constitution ratios of the medicine expenses were the highest,and those in the 5 years were all above 44%. The results of the univariate and multi?factor analyses showed that the hospital stays,the amount of intraoperative bleeding,liver function classification,postoperative complications,age,portal hy?pertensive gastropathy were the influencing factors of the hospital expenses. Conclusion Presently,the burden of the direct hospital expenses of the patients with splenomegalic advanced schistosomiasis is still heavy. The government should further im?prove the proportion of the compensation of medical assistance and perfect the medical aid scheme. Meanwhile ,the hospitals should strengthen the management and standardize medical behavior to reduce the hospitalization expenses of the patients.

Objective To summarize the experience of clinical application of combining double suture fixation and resection of partial fat retro-orbicularis oculus in some specially difficult blepharoplasty.Methods During upper blepharoplasty,patients with heaviness and bulkiness in the both upper eyelid and lateral upper orbital region,we combined double suture fixation and resection partial fat retro-orbicularis oculus.First,partial pretarsal bulky fat was resected,and to form skin-orbicularisoculi composite below incision line.And then,some thickened fat retro-orbicularis oculus was resected,which was also named preseptal and retro-orbicularis oculus fat (ROOF).Double suture fixation techniques were applied to form dynamic and physiological double eyelid.Results 146 cases had satisfactory effectiveness,except for 2 cases with secondary operation because of some superficial double eyelid creases,and 1 case had hematoma,and 3 had transient numbness in the lateral supraorbital nerve region.They were satisfied with healthy eyelid skins,concealed incision and non-serious complications followed at 3-24 months postoperatively.Conclusions Combining double suture fixation and resection of partial fat retro-orbicularis oculus would appear to be a useful adjunct to standard blepharoplasty techniques in selected patients.

OBJECTIVE: To investigate the dynamic trends of activities of matrix metalloproteinase (MMP)-2/9 and protein expressions of their inhibitors-tissue inhibitor of matrix metalloproteinase (TIMP)-1/2 during the progression of pulmonary fibrosis in rats so as to get insight of the roles played by MMP-2/9 in lung injury and fibrogenesis. METHODS: Forty-eight SD rats were randomly divided into normal control group (n=18) and bleomycin (BLM)-treated group (n=30). The pulmonary fibrosis was induced by intratracheal injection of BLM once. At the consecutive time of 1 day, 3 days, 1 week, 2, 3, and 4 weeks after intoxication, the lung-to-body weight ratio was calculated and the inflammation and collagen deposition in lung tissue were checked by HE and Masson stainings respectively. Meanwhile, the content of hypdroxyproline (Hyp) in lung tissue was assayed with Jamall's method, the protein expressions of MMP-2/9, TIMP-1/2 were examined by Western blotting, and the activities of MMP-2/9 were detected by gelatin zymography. RESULTS: The histopathological changes in lung tissue in the BLM-treated group from 1 day to 2 weeks after intoxication presented local lesions, broadened alveolar wall and septum, infiltration with lots of inflammatory cells and few of fibroblasts inside alveolar space and septum. At this early stage in the BLM-treated group, the lung-to-body weight ratio was increased significantly, the protein expressions and activities of MMP-2/9 were obviously increased especially for activity of active MMP-2, and the protein expressions of TIMP-1/2 were also increased gradually, as compared with those in the normal control group. From 3 to 4 weeks after intoxication in the BLM-treated group, the alveolar structure was damaged, parts of the alveolar space collapsed and replaced by collagens and fibroblasts, and the alveolar wall and septum obviously widened with remarkable fibrotic characteristics, as compared with those in the normal control group. Meanwhile, the lung-to-body weight ratio and the activities of MMP-2/9 were decreased in the BLM-treated group as compared with those in the same group at 2 weeks after intoxication, but the content of Hyp and the protein expressions of TIMP-1/2 were both increased dramatically, especially at 4 weeks after intoxication. CONCLUSIONS: During the lung fibrogenesis induced by BLM in rats, the alveolar inflammation is the most important alteration with enhanced MMP-2/9 activities in the early stage. While in the late stage, the main change is displayed as pulmonary fibrosis, characterized by increased TIMP-1/2 and declined MMP-2/9 activities.

Objective To compare the screening effects between Wells and revised Geneva scores on suspected acute pulmonary thromboembolism (APTE),and to explore a optimum screening method for APTE in the emergency department of China.Methods The study was carried out by using random,crossed,prospective methods to compare the screening effects between Wells and revised Geneva scores for 167 suspected APTE patients in the emergency department of the First Affiliated Hospital of Xiamen University.Results The areas under the receiver operating characteristic curve of Wells and revised Geneva scores for screening APTE in the emergency department were (0.917 ± 0.022 ) and (0.927 ± 0.020),respectively ( P ＜ 0.05 ).The diagnostic concordance between the two score systems for predicting APTE was poor (Kappa value =0.276 ). In addition, the difference between their hierarchical discrimination for the possibility of APTE was statistically significant ( P ＜ 0.05 ).Compared with revised Geneva score,fewer patients were diagnosed with low clinical probability of APTE and more patients were diagnosed with intermediate or high clinical probability of APTE through Wells score.The patients with low chnical probability of APTE were excluded from pulmonary embolism in Wells or revised Geneva score.At intermediate clinical probability,the accuracy rate of Wells score for predicting APTE (9.64％) was lower than that (32.84％ ) of revised Geneva ( P ＜ 0.05 ).At high clinical probability,there was no significant difference between their accuracy rate [ (67.24％ vs.86.21％),P＞0.05]. Conclusions Revised Geneva score is more suitable than Wells score in screening suspected APTE patients in the emergency department in our country.
