Methods One hundred and twelve healthy and clean SD rats were randomly divided into the high dosage (60 mg/L),the moderate dosage(40 mg/L),the low dosage(20 mg/L) and the control group(distilled water),28 in each group,the males and females in the same number,the administration was conducted through drinking water,for 8 consecutive weeks. In the 4th and 8th weeks,the length of jejunum villus,the depth of jejunum gland and the thickness of jejunum wall were measured,the ratio of villus length and gland depth were counted and the pathological examination was done. Results With the increase of ammoniummeta vanadate,the weight of SD rats,the jejunum villus length,the depth of the jejunum gland,the wall thickness had showed a downward trend,the ratio of villus length and gland depth were significantly lower (P

Objective To compare postoperative pulmonary infection in patients undergoing surgical operation at different surgical opportunities.Methods Patients who underwent surgical operation in a hospital from January to December 2014 were surveyed retrospectively,patients' data were reviewed,patients with postoperative pulmonary infection were compared.Results A total of 20 343 surgical patients were investigated,227(1.12％) had postoperative pulmonary infection.Postoperative pulmonary infection rate in patients undergoing emergency operation was higher than that of selective operation (5.13 ％ vs 0.70 ％,x2 =307.49,P＜0.001).Postoperative pulmonary infection rates in patients undergoing emergency neurosurgical,general surgical,and cardiothoracic surgical operation were all higher than selective operation (all P ＜ 0.001).Among patients with pulmonary infection following emergency operation,the proportion of those who aged ＜60 years,with preoperative irrational antimicrobial use,cardiovascular disease,hypertension,and tracheotomy were all higher than those who received selective operation (all P＜0.05);the proportion of patients with cancer is lower than that of elective surgery patients(P＜0.05).Conclusion Postoperative pulmonary infection rate in patients undergoing emergency operation is higher than selective operation,postoperative pulmonary infection rates in patients undergoing emergency neurosurgical,general surgical,and cardiothoracic surgical operation are high.Patients with cardiovascular disease and hypertension are the focus of protection;for elective surgery,cancer patients are the focus of protection.

Complement system is a reaction system comprising 35 proteins with enzyme activity common in serum,tissue fluid and cell membrane. It plays an important role in anti-infection. Abnormal complement activation is involved in incidence and progression of many inflammatory diseases. The complement is activated through typical,alternative and agglutinin pathways. Following cardiovascular stent implantation,the vessel endothelium of patients with coronary atherosclerotic heart disease is damaged; serum complement C3 could enter the arterial wall to damage arterial cells to enhance the permeability release antigenic components of vessel wall,and induce antibody production. The fixing immune complex is formed and induces platelet aggregation,attachment or lipidoses. Although humoral immunity becomes accentuated following cardiovascular stent implantation,the capability to resist microorganism is reduced,which stimulates self-protection of C3,aggravates inflammation,increases circulation complex,activates complement system and aggravates endothelial injury. C3 plays an essential role in occurrence and development of ischemic cardiovascular disease,and is an important cause for restenosis and thrombosis following cardiovascular stent implantation.

Objective To study the incidence rate and correlation of anomalous pancreaticobiliary ductal junction( APBDJ) for patients with biliogenic chronic pancreatitis (BCP). Methods From January 2000 to January 2012,the data of 1 373 patients who underwent ER-CP,MRCP or T-Tube cholangiography in which both biliary and pancreatic ducts in our hospital were analyzed retrospectively. Results Bil-iogenic chronic pancreatitis was found in 47 patients,of which 17 patients with APBDJ. The mean (SD) common channel was (19. 3±7. 2) mm in length ( range 11~40 mm) . Conclusion APBDJ may be the important reason of BCP among Chinese patients.

Objective To analyze the effect of different postoperative nutrition:enteral nutrition( EN) and parenteral nutrition( PN) in patients with colorectal cancer. Methods 84 patients with colorectal cancer were collected in this study from Jan. 2012 to Jan. 2014, and they were divided into the EN group (43 cases) and the PN group (41 cases). They were given EN or PN after operation. The nutritional parameters such as ALB, TF and PA were detected before surgery and 7 days after operation, Observe the adverse reaction, time of gastroin-testinal function recovery, infection and costs after operation. Results There was no statistical difference (P>0. 05) in the nutritional pa-rameters and rate of adverse reaction between the two groups. The rate of infection in EN group was lower than that in PN group(P<0. 01), and the time of gastrointestinal function recovery was shorter in EN group compared with that in PN group (P<0. 01). Conclusion EN is better in recovery of gastrointestinal function, and there is less complication compared to PN. EN have clinical application value for patients with gastrointestinal cancer.

Objective To understand the effect of vanadium to liver ultramicro structure in SD rats.Methods One hundred and fifty generaMevel SD rats of 2 months were randomly divided into control groups,30 in each,the males and females were equivalent,treated with ammonium metavanadate at doses of 0,10,20,40,60 mg/L through drinking water.After 2,6 and 10 weeks of treatment,6 rats from each group were weighed and the changes of ultramicro-structure in the liver were examined with electron microscope.Results As the increasing of dose,the increase in body weight showed a downward trend,but the coefficient of liver showed a increasing trend,the consistent performance was seen in male and female rat.After two weeks of exposure,the rats acted,ate and drank less,hair roughing and no shining,often getting together were seen.After 10 weeks,the rats had not the basic activities,the hair was disheveled and loose,some died,the structure of mitochondria and endoplasmic reticulum was normal in the 10,20,40 mg/L group,the number of endoplasmic reticulum increased,in 60 mg/L group,the rough endoplasmic reticulum vanished,the liver cytoplasm had a swelling phenomenon,the mitochondria reduced.Conclusion Vanadium have little effect on the liver cells of rats in low exposure level,but high level exposure may damage the liver cells in rats.

Objective To explore the sensitivity of contrast-enhanced ultrasound (CEUS) and ultrasonic elastography(UE) in detecting different sizes of thyroid papillary carcinoma.Methods 64 cases of thyroid papillary carcinoma were divided into two groups according to the diameter size(group 1,≤1 cm;group 2,＞ 1 cm) and examined by the contrast-enhanced ultrasound and elastography,then the features were analyzed and the sensitivity for detecting of the two methods in different groups were compared.Results The sensitivity for detecting in CEUS was higher than in UE,which had significant difference between two methods.CEUS and UE were valuable for detecting and they had no difference in sensitivity for detecting in group 1.There was a significant difference in sensitivity for detecting between two methods in group 2.Conclusions Both CEUS and UE were valuable in diagnosis of thyroid papillary carcinoma and the sensitivity for detecting in CEUS is higher than in UE in group 2.

OBJECTIVE: To explore the effects of Yiweining Recipe (YWNR), a compound Chinese herbal medicine, on expressions of metalloproteinase-2 (MMP-2) and cyclooxygenase-2 (COX-2) mRNAs in rats with endometriosis (EM). METHODS: Operational self-transplantation was applied in establishing the rat models. Detection of MMP-2 and COX-2 mRNAs was conducted with hybridization in situ. RESULTS: There were significant differences in the expressions of MMP-2 and COX-2 mRNAs between the untreated group and the high-dose YWNR-treated group. YWNR could reduce the expressions of MMP-2 and COX-2 mRNAs. CONCLUSION: YWNR can treat EM through reducing the positive expressions of MMP-2 and COX-2 mRNAs.

Objective To evaluate the diagnostic value of thyroid microcarcinoma using contrastenhanced ultrasound(CEUS).Methods The CEUS characteristics of 31 lesions in patients with thyroid microcarcinoma which were confirmed by surgery and pathology were retrospectively analyzed.[Results]The enhancement features of 31 lesions were hypoenhancement,morphological irregularity,and lack of a complete envelope.The time intensity curve showed late washed in and late washed out.The start-time of the lesions was later than that of normal thyroid tissue.The enhancement intensities of the lesions were lower than that of normal thyroid tissue.Conclusions The contrast enhancement patternshypoenhancement,suggested that the CEUS might provide a useful,quantitative analysis method for the diagnosis of thyroid microcarcinoma,which can improve diagnostic confidence in thyroid microcarcinoma.
