Objective To evaluate the value of using fluorescence in situ hybridization (FISH)technique for the detection of chromosome aberration of urine exfoliated cells for the diagnosis of bladder tumor.MethodsFISH technique were used to detect the abnormalities of chromosome 3,7,17 and 9p16 site from 20 normal people, and to establish the threshold.The morning's first urinations were available from 75 patients with bladder cancer and 25 patients without urothelial tumor, then were detected using FISH technique and urine cytology respectively.The sample was considered positive if two or more probes results higher than the criteria,or one probe has two or more abnormal results.Results The sensitivity of single using were 73.3％ (55/75),76.0％ (57/75),62.7％ (47/75) and 62.7％ (47/75) for the 4 probes (3,7, 17 and 9p16)respectively.The sensitivity of combined detection was 85.3％ (64/75) and specificity was 96.0％ (24/25) The sensitivity and specificity of urine cytology examination was 9.3％ (7/75) and 100％ (25/25) .The sensitivity of FISH examination was significantly higher than that of urine cytology examination (85.3％ vs 9.3％ ,x2 = 57.00, P ＜ 0.001) .Sensitivity of FISH examination was not correlated with cancer pathologic grading(low vs high : 84.2％ vs 86.5％, x2 = 0.08, P ＞ 0.05)and clinical stage (ta-tl : 82.9％, t2-t4 :87.5％, x2 = 0.32 ,P ＞ 0.05) .ConclusionFISH technique is a non-invasive and effective method for the early diagnosis of bladder tumor and is more sensitive than urine cytology.Furthermore, FISH technique can be used to predict the tumor's biological behavivor and prognosis.

Osteopontin (OPN) is a secreted O-glycosylated phosphoprotein that exists in a variety of tissues and body fluids, with a variety of biological activity. Integrin α_vβ_3 is the main receptor. OPN mainly involves in cell proliferation, differentiation, migration and adhesion. The study of OPN at home and abroad mainly focuses on the bone resorption, angiogenesis, atherosclerosis, digestive system, urinary system, wound healing, skin fibrosis, liver fibrosis, kidney fibrosis, etc.But reports about OPN in pulmonary fibrosis are much less, now the relationships between OPN and pulmonary fibrosis are reviewed.

Objective To investigate the feasibihty and effectiveness of the fluorescence in situ hybridization(FISH)technique in the diagnosis of renal pelvic tumor.Methods FISH technique were used to detect the abnormalities of chromosome 3,7,17 and 9 p16 from 20 people without malignancy.The morning's first urine were availahled from 15 patients with hematuria and suspected of renal mass by imaging,then were studied by FISH technique and urine cytology respectively.The sample was considered positive if two or more probes results were higher than the criteria,or one probe had two or more abnormal results.Results Eight of 15 patients with hematuria were renal pelvic urothehal carcinoma,5 were renal clear cell carcinoma,1 was renal chromophobe cell carcinoma,1 was xanthogranulomatous pyelonephritis,confirmed by pathology.All of the 8 renal pelvic carcinoma were considered positive by FISH technique,while only 1 was considered positive by urine cytology.The variation rate of chromosome 3,7,17 were 100%(8/8)and chromosome 9 p16 was 75%(6/8).Six of 7 non-renal pelvic carcinoma were negative by FISH technique,but all Were negative by urine cytology.Conclusion FISH technique is a non-invasive and effective method for the diagnosis of renal pelvic tumor,and it's more sensitive than urine cytology.

Aim To investigate the effect of puerarin(Pue)on the experimental insulin resistance(IR)and the mechanism of Pue-treated metabolic syndrome(MS).Methods IR rat model was induced by i.v.small dosage streptozotocin(STZ)and high fatty diet.The effect of Pue on insulin sensitivity was studied by reformed hyperinsulinism euglycemia clamp technique(HEPC)on IR rats.Results The basic blood glucose(BBG),basic blood plasma insulin(BINS)and stable basic blood plasma insulin(SINS)of IR rats induced by high-fat feed were higher than those of control group,and those of the group treated by Pue were observably lower than those of IR model group.In HECT text,the average rate of glucose injection of IR model group was lower than that of control group from 60 min to 120 min,but the rate of high dose and middle dose of Pue group was significantly higher than that of IR model group.Conclusion The results suggest that Pue can improve the insulin sensitivity,and reduce basic blood glucose and blood plasma insulin of the experimental insulin resistance rats.

ObjectiveTo observe the influence of Danshen injection on the serum levels of TNF-α,IL-6 in patients with acute pancreatitis(AP).Methods70 patients with AP were randomly divided into the experimental and control group.The two groups were given conventional anti-inflammatory,antisecretory,antispasmodic,inhibition of pancreatic secretion treatment,and the experimental group were treated with Danshen injection.Before trealment and 1,2,4,6 days after treatment,the serum TNF-α,IL-6 levels were measured in both groups.The time of blood and urine amylase(AMS) returned to normal was observed in both groups.Results2,4,6d after treatment,the serum TNF-α,IL-6 of the observation group were lower than that of the control group( all P ＜ 0.05 ) ;The blood AMS recovery time of the observation group was ( 2.55 ± 0.71 ) d,which had no significant difference with that of the control group(2.46 +0.82)d(t =0.32,P ＞0.05 ),while urinary AMS recovery time of the observation group was (4.30 ±0.72 ) d,which was shorter than that of the control group ( 6.84 ± 0.88 ) d ( t =0.02,P ＜ 0.05 ).ConclusionDanshen injection could reduce the serum TNF-α,IL-6 levels in patients with AP,and had no effect on the serum amylase,with the trend of faster lower urinary amylase.

Objective:To explore the influence of rosuvastatin in the lipid levels, atherosclerosis plaque and apoptosis in the plaque of atherosclerotic apolipoprotein E (ApoE)-knockout mouse models, and to clarify the mechanism of rosuvastatin in inhibiting atheromatous plaque and apoptosis in the plaque.Methods:Thirty healthy six-week old male mice were randomly divided into high fat diet group (n=10),rosuvastatin group (n=10)and general diet control group (n=10).The mice in first two groups were fed with high fat diet,and the mice in general diet control group were fed with general diet;4 weeks later the mice in three groups were respectively given 0.9% NaCl solution,rosuvastatin (10 mg·kg·d-1 )and 0.9% NaCl solution by gavage for 8 weeks.And then ELISA was used to detect the serum lipid levels,the area of atherosclerotic plaque was measured by HE staining, and the apoptosis in plaques was detected by TUNEL method;the expression of apoptosis-assoicated gene Bax protein was measured by immunohistochemical staining.Results:Compared with high fat diet group,the levels of total cholesterol (TC)and low density lipoprotein cholesterol (LDL-C)of the mice in rosuvastatin group were significantly decreased (P<0.05 or P<0.01),and the 1evel of high density lipoprotein cholesterol (HDL-C)was significantly increased (P<0.01).The aortic atherosclerotic plaque of the mice in high fat diet group was massive with a great quantity of foam cells, cholesterol crystal, necrotic cells and inflammatory cells in the plaque;the aortic atherosclerotic plaque of the mice in rosuvastatin group was smaller with less foam cells,necrotic cells and inflammatory cells;the aortic atherosclerotic plaque area of the mice in rosuvastatin group was significantly smaller than that in high fat diet group (P<0.01);the apoptotic index in the aortic atherosclerotic plaque of the mice in rosuvastatin group was significantly lower than that in high fat diet group (P<0.01).Compared with high fat diet group,the expression of Bax protein in rosuvastatin group was significantly decreased.Conclusion:Rosuvastatin may inhibit the progression of atherosclerotic plaque and the apoptosis in plaques through mitochondrial pathway.

Drug-induced liver injury (DILI) is a major reason for the recall of marketed drugs and the failure of clinical trials. Detection of potential liver injury remains a challenge for clinical management and preclinical drug safety studies. Currently, serum levels of alanine aminotransferase and aspartate aminotransferase are the gold standards for evaluating liver injury. However, these biomarkers are nonspecific and insensitive, and often result in false-positive results. Therefore, researchers have never stopped searching for the biomarkers of DILI with high sensitivity and specificity. This review summarizes recent research progress in the biomarkers of DILI to better predict and diagnose DILI.

Objective To prepare an influenza A(H1N1) split-virus vaccine and observe its safe-ty and effectiveness. Methods According to the process for preparing seasonal flu split-virus vaccine two batches of vaccine were prepared with the flu A (H1N1) vaccine virus strain recommended by WHO. The pilot products were tested against the requirements of flu split-virus vaccine. Results The quality of the pi-lot vaccine has been tested by National Control Laboratory and conformed to the requirements. Nine hundred and sixty volunteers received one dose of vaccine containing either 15 μg or 30 μg of hemagglutinin. The re-suits indicated the both seroconversion rate and protection rate were higher the 70%. The GMT of HIAb of the volunteers who received 1 dose of 15 μg increased significantly by 15, 39, 37 and 25 times compared to those before vaccination in the age groups of 3-11, 12-17, 18-59 and ≥60, respectively. And 26, 72, 68 and 36 times rise were found in the postvaccinated volunteers of 30 μg group. The total adverse reaction rates of 15 μg and 30 μg dose group were 29.38% and 43.75%, respectively. The grade 2 adverse reaction rates of 15 μg and 30 μg dose group were 6.25% and 15.42%, and the grade 3 adverse reaction rates of 15 μg and 30 μg dose group were 0.83% and 1.46%, respectively. No serious adverse reactions were found. Conclusion The influenza A (H1N1) split-virus vaccine prepared according to the requirements of season-al flu vaccine is safe and effective.

Objective To compare the hemostatic safety and efficacy of a new butterfly femoral artery compression device (FACD) with those of manual compression (MC) in patients undergoing percutaneous peripheral endovascular interventions via femoral artery. Methods A total of 283 patients, who received percutaneous endovascular interventions via femoral artery during the period from September 2016 to December 2017, were enrolled in this study. After endovascular intervention, 167 patients received FACD to make hemostasis (FACD group), and 116 patients received MC hemostasis (MC group) . The patient's comfortableness, time used for hemostasis (min), limb immobilization time (h), and the incidence of vascular complications in both groups were analyzed. Results All 283 patients were included in analysis, the results indicated that the hemostatic success rates in FACD group and MC group were 96.4％ (161/167) and 94.0％ (109/116) respectively, the difference between the two groups was not statistically significant (P>0.05) . The postoperative Kolcaba Comfort Scale score of FACD group was (85.0 ±11.2) points, which was remarkably higher than (58.4±11.7) points of MC group (P<0.05), the time used for hemostasis in FACD group was (9.2 ±2.2) min, which was strikingly shorter than (18.5 ±2.9) min in MC group (P <0.05) . The limb immobilization time in FACD group was (10.4±2.4) hours, which was obviously shorter than (23.1±4.1) hours in MC group (P <0.05) . The incidence of vascular complications in FACD group was 3.6％, which was dramatically lower than 9.5％ in MC group (χ2=4.206, P=0.04) . Conclusion The use of the new butterfly FACD can promptly, safely and effectively stop bleeding of femoral artery puncture site. The new butterfly FACD is superior to MC in shortening hemostatic time and limb immobilization time, in reducing incidence of vascular complications, as well as in improving patient's comfortableness degree.
