ABSTRACT
Objective To discuss the application value of small doses penehyclidine hydrochloride in painless colonoscopy examination. Methods From July 2012 to January 2013, 90 patients who planed to have painless colonoscopy were randomly divided into 3 groups with each group 30 cases. Before anesthesia, giving small doses of penehyclidine hydrochloride to small-dose group, giving conventional dose of penehyclidine hydrochloride to routine-dose group, and giving atropine intravenous administration to atropine group. Observe the smoothly de-gree, and check the heart rate, mean arterial pressure and postoperative adverse reactions of three groups. Results There was no obvious difference among the three groups in trems of smooth degree and oxyhemoglobin saturation. In small-dose group, heart rate and mean arterial pressure before and after the examination were better than that of routine-dose group and atropine group, and there were obviously lower inci-dence of postoperative adverse reaction compared with the routine-dose group and atropine group. Conclusion Giving small-dose of penehy-clidine hydrochloride before anesthesia of painless colonoscopy examination can significantly improve the effect of examination, and it can re-duce the incidence of postoperative adverse reactions.
ABSTRACT
Objective To explore the clinical efficacy and value of azo steen,montelukast sodium combined with levocetirizine in the treatment of chronic urticaria. Methods 150 cases with chronic urticaria admitted in department of dermatology of Hubei Zhongshan Hospital were divided into A,B and C group,each group had 50 cases. Patients in group A were received montelukast sodium and levocetirizine treatment,which in group B were received montelukast sodium and azo steen treatment,group C were received above three kinds of drug treatment. Total effective rate,adverse reaction and safety in three groups were observed and compared. Results Total effective rate of group C was significantly higher than A and B group(P<0.05), and the safety of group C were better than A and B group(P<0.05 ),too. The occurrence of adverse reaction in group C was significantly less than that in group A and B (P <0.05 ).Conclusion Azo steen,montelukast sodium combined with levocetirizine has good efficacy in treatment of chronic urticaria. It can relieve itching wheals and other symptoms in a short time,with less adverse reaction.
ABSTRACT
Objective To evaluate the efficacy and safety of use of platelet membrane glycoprotein (GP) Ⅱ b/Ⅲ a inhibitor tirofiban for percutaneous coronary interventional (PCI) in elderly patients with acute ST segment elevation myocardial infarction (STEMI).Methods A total of 120 elderly patients who suffered from STEMI and underwent PCI were selected from July 2007 to November 2009.The patients were randomly assigned to control group, standard-dose tirofiban group and low-dose tirofiban group.We observed coronary blood reflow, the bleeding complication, coagulation factor(TF,vWF) and cell adhesion molecular(sICAM-1 and sVCAM-1).Results Total 116 patients accomplished this study (control group: 38 cases; standard-dose group: 39 cases; low-dose: 39 cases).The percentages of TIMI 3 flow after PCI were higher in the two tirofiban groups than in control group (P<0.05).The incidences of bleeding complications in both tirofiban groups (12.8%,5.1%) were higher than that in control group (2.6%, P<0.05).The concentration of TF, vWF,sICAM-1 and sVCAM-1 were lower in both tirofiban groups than in control group(P< 0.05).Conclusions GP Ⅱ b/Ⅲ a inhibitor tirofiban can benefit the elderly patients with STEMI referred for PCI therapy, low-dose tirofiban may offer almost the same level of efficacy as standard-dose, with less associated bleeding.
ABSTRACT
Objective To establish a sandwich enzyme-linked immunosorbent (ELISA) method for early diagnosis of hepatitis C. Methods Immunization of Balb/c mice with hepatitis C core antigen were prepared by genetic engineering. Mouse monoclonal antibodies (McAb) to anti-HCV-core Ag were obtained. A sandwich ELISA kit for detecting HCV-core Ag was developed by using four strains of anti-HCV-core Ag McAb. One hundred and twenty five serum specimens with increased ALT but negative for anti-HCV, anti-HIV, and anti-Tp tests were tested. Results Nine of the 125 specimens were positive for HCV-core Ag. Conclusion The double sandwich ELISA kits for detecting HCV-core Ag may be useful for the early diagnosis of hepatitis C .
ABSTRACT
Objective To study the connection between MRI characteristics of spinal cavernous hemangioma(SCH)and its clinical and pathological features.Methods 20 cases of SCH confirmed by pathology were retrospectively analysed.The characteristics of MRI signal intensity were analysed in comparison with the clinical manifestations and pathology.Results Among the 20 cases,5 lesions located in the cervical segment of spinal cord,12 lesions in the thoracic segment,2 in the lumbar segment and 1 in the thoracic-lumbar segement.SCH could be devided into four patterns:intramedullary lesion,epidural lesion,intradural-extramedulary lesion and vertebral lesion.The typical MRI characteristics of SCH were mixed signal intersity on T_1 or T_2 weighted images,low signal intensity ring could be seen around the lesions and more pronounced on T_2 images.Spinal cord compression syndrome was the main clinical manifestation.Cavernous hemangiomas were red or purple mulberg-like lesions which were composed of dilated,thin-walled vessel with a simple endothelial lining and a variably thin fibrous adventitia under the microscope.Conclusion MRI is the most reliable method in diagnosing SCH,MRI characteristics of signal intensity of SCH are correspond with their clinical and pathological features.
ABSTRACT
Objective To research the blood supply changes of uterine and fibroid before and after UAE for uterine fibroids.Methods Sixteen patients with symptomatic uterine myoma were treated by Seldinger's bilateral uterine arteries embolization.The same level dynamic enhanced CT scans were undertaken 7 days before and after the procedure with another one 3 months later.The CT values of uterine and fibroid were measured and analyzed. Results 16 cases finished the same level dynamic CT enhancement scans successfully. The dynamic enhanced curves and the CT values showed no significant difference in uterine but had significant difference in fibroids. The fibroids were in a state of ischemia after the procedure.Conclusions Selective uterine arterial embolization is a new safety and effective method for treatment of uterine myoma.
ABSTRACT
Objective To study the influence of economic level on nutrition intake and status in adult. Methods The survey of income level, and nutrition intake and status of adults in 2000 in the city and rural area of Hunan province was carried out, and was compared with the data of the first survey in 1991. Results With the income increasing, the intake of protein,calcium,iron, retinal EQ and riboflavin increased from 1991 to 2000. In the population with low and middle income, the inadequate intake of calcium, retinal EQ and riboflavin was common. With the economic level being raised, the number of people with overweight or obesity(BMI≥25) increased, especially in city. But the number of people with malnutrition (BMI
ABSTRACT
Objective To observe the level changes of serum interleukin-18(IL-18) and tumor necrosis factor-?(TNF-?) in alcohol liver disease of rats.Methods The dose of 56% alcohol [5～9 g/(kg?d)] was administeredvia gastrolavage once daily for 12 weeks in ALD model rats.The control rats were grven the same volume of saline.The rats were killed at the end of 4,8,12W.The pathological changes of liver were observed under light microscope after HE staining,and the levels of IL-18 and TNF-? in serum was determined with ELISA.Results The tissues of model rats showed various changes of chronic alcohol liver disease at the end of 4,8,12W,such as: fatty degeneration,inflammatory changes and fibrosis.The levels of ALT and AST in models were obviously higher than those of the controls(P
ABSTRACT
AIM: To study the effect of signal transducer and activator of transcription 6 (STAT6) on airway inflammation of rats with asthma. METHODS: Male Sprague-Dawley rats were randomly divided into control group and asthma group. The lung tissue was sampled from the left lung. Bronchoalveolar lavage fluid (BALF) was collected from the right lung. The concentrations of IL-4 in serum and BALF were measured by sandwich ELISA. STAT6 protein and STAT6 mRNA were observed in the epithelial cells of bronchus by the technique of immunohistochemistry and in situ hybridization. RESULTS: (1) The concentrations of IL-4 in BALF and serum of asthma group were significantly higher than those in control group (P
