Purpose To investigate the association of multi-slice spiral CT (MSCT) appearances and ischemia time as well as ischemia degree through both unenhanced and contrast-enhanced MSCT scans, then to investigate the value of MSCT in diagnosing acute mesenteric ischemia (AMI) by comparing the MSCT findings with pathologic examinations after establishing canine's AMI model. Materials and Methods 18 healthy hybrid canines were successfully punctured into the right femoral artery through seldinger's technique and injected absolute ethanol into the distal branches of superior mesenteric artery (SMA) for embolization via a 5F Cobra catheter. All experimental canines were underwent both unenhanced MSCT and enhanced CT scans no matter before nor after embolization. Every 3 canines were put to death randly each hour and ischemia bowel biopsies were examined. Results The AMI's models were suceessfully established in all 18 canines. The MSCT appearances were not same in different periods. Mesenteric stranding, bowel-wall thickening and luminal dilatation occurred in early periods and ascites, intramural gas and portal venous gas occurred lately. The contrast-enhanced degrees of abnormal bowel walls after embolization were declined than that of preoperation. The canines of three-hour to six-hour ischemia groups developed microscopic and gross changes of bowel ischemia. Conclusion MSCT can make the diagnosis of AMI accurately and the appearances of CT were gradually more variety along with the ischemia time longer. The contrast-enhanced degrees of abnormal bowel walls were negative correlation with ischemia time as well as ischemia degree.

Objective To investigate the correlation of left ventricular ejection fraction (LVEF) as well as serum levels of NT-proBNP, Hcy and D-Dimer (D-D) with different traditional Chinese medicine (TCM) syndrome types of chronic heart failure (CHF). Methods A total of 178 CHF patients were divided into heart function normal ejection fracture group (HF?NEF, n=86) and heart function reduction (HFREF, n=92) according to their LVEF performance. Another 35 cases with nor?mal cardiac function were included in control group. All CHF patients was also divided into 3 TCM syndrome types:both de?ficiency of Qi and Yin syndrome group(n=64),Qi asthenia causing blood stasis syndrome group(n=59) andYang defi?ciency water stop group (n=55). All patients were examined with cardiac color doppler and LVEF values were recorded. And serum NT-proBNP、Hcyand D-D levels were all quantified. Results As to serum levels of NT-proBNP, Hcy and D-D, they were higher in HFREF group than those in HFNEF group than those in control group. On the other hand, LVEF was lowest in HFREF group but highest in control group. All differences were statistically significant (P<0.05). Among patient in HFNEF group, LVEF in theYang deficiency water stop groupwas lower than that inboth deficiency of Qi and Yin syn?drome group(P<0.05). Serum levels of NT-proBNP, Hcy, and D-D were not significantly different between different TCM syndrome groups. By contrast, among patients in HFREF group, LVEF values did not differ significantly between different TCM syndrome groups. Serum level of NT-proBNP was lower inboth deficiency of Qi and Yin syndrome groupthan that inQi asthenia causing blood stasis syndrome group than that in Yang deficiency water stop group. As to serum levels of Hcy and D-D, they are higher inYang deficiency water stop groupthat those inboth deficiency of Qi and Yin syndrome group and Qi asthenia causing blood stasis syndrome group(P<0.05). Conclusion Patients with different TCM syn?drome types of CHF present different levels of serum NT-proBNP, Hcy, D-D level and LVEF. Changes of indicators in HFREF groups are more obvious than they did in HFNEF group.

Objective To compare the therapeutic efficacy between medicinal cupping and collateral-pricking bloodletting therapy in treating lumbar intervertebral disc herniation (LIDH) and non-specific low back pain.Method Sixty LIDH patients were randomized into treatment group 1 and control group 1, 30 cases in each group. Sixty non-specific low back pain patients were randomized into treatment group 2 and control group 2, 30 cases in each group. Treatment group 1 and 2 were intervened by medicinal cupping, while control group 1 and 2 were by collateral-pricking bloodletting. The Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) were observed before and after intervention.Result The VAS and ODI scores were significantly changed after intervention in treatment group 1, treatment group 2, and control group 2 (P<0.05). The VAS score was significantly changed after intervention in control group 1 (P<0.05); the ODI score didn’t show significant change after intervention in control group 1 (P>0.05). After treatment, there was a significant difference in comparing the ODI score between control group 1 and control group 2 (P<0.05).Conclusion Medicinal cupping and collateral-pricking bloodletting are both effective in treating chronic low back pain, and medicinal cupping has its advantage in improving ODI compared to the bloodletting therapy.

Objective To explore the effects of multidisciplinary comprehensive pulmonary rehabilitation on aged patients with pneumo-coniosis. Methods From January, 2012 to January, 2015, 85 old stable inpatients with pneumoconiosis were divided into control group (n=40) and rehabilitation group (n=45). Both groups accepted routine medicine, while the rehabilitation group received multidisciplinary com-prehensive pulmonary rehabilitation for twelve weeks. They were assessed with cardiopulmonary exercise test, BODE index and quality of life before and after treatment. Results The maximum work, maximal oxygen uptake, 6-minute walk distance, scores of modified Version of the British Medical Researsh Council Respiratory Questionnaire, BODE index, activities of daily living, social activities, depression and anx-iety improved in the rehabilitation group after treatment (t>3.379, P<0.01), and were better than those in the control group (t>2.201, P<0.05). No imporvement was found in all the indices in the control group after treatment (t<2.339, P>0.05). Conclusion Multidisciplinary comprehensive pulmonary rehabilitation can effectively improve exercise tolerance and quality of life in aged patients with pneumoconiosis.

Objective To observe the antimicrobial effect of a kind of Chinese medicine Qingre compound preparation on the common pathogenic bacteria of upper respiratory tract infection (URTI). Methods A total of 163 common pathogen?ic bacteria of URTI was selected in this study, including 74 non extended-spectrum β- lactamases (ESBLs)-producing Gram-negative bacteria (33 Escherichia coli, 24 Klebsiella pneumonia and 17 Pseudomonas aeruginosa), 10 ESBLs-produc?ing Gram-negative bacteria (6 Escherichia coli and 4 Klebsiella pneumoniae) and 79 Gram-positive bacteria [11 methicil?lin-resistant Staphylococcus aureus (MRSA), 46 methicillin-sensitive Staphylococcus aureus and 22 Streptococcus pneu?moniae]. Agar dilution method was adopted to perform the quantitative drug sensibility test. Agar plates that contained differ?ent concentrations of Qingre compound preparation were prepared. The bacterial suspension was planted on the plates. Then we observed the plates after incubation, and recorded the minimum inhibitory concentration (MIC). Results The antimicro?bial rates of Qingre compound preparation were 88, 176 and 22 g/L for MIC90 of Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. The antimicrobial effects of Qingre compound preparation were coincident on the MIC 90 of ES?BLs-producing strains and non ESBLs-producing strains. The accumulated antibacterial rates of different concentrations of medicine to Pseudomonas aeruginosa were the highest. The MIC90 values of Qingre compound preparation were 11, 11 and 22 g/L for MSSA, MRSA and Streptococcus pneumoniae. The MIC90 of MRSA was coincident with MSSA, but MIC50 of MRSA was slightly higher than that of MSSA. The accumulated antibacterial rates of different concentrations of medi cine to MSSA and MRSA were all higher than those of Streptococcus pneumonia. The accumulated antibacterial rate of MSSA was similar with that of MRSA. Conclusion The Chinese medicine Qingre compound preparation could restrain common patho?genic bacteria of URTI except Klebsiella pneumoniae. The antibacterial effect of Qingre compound preparation is significant?ly better in Ggram-positive bacteria than that of Gram-negative bacteria.

Objective To observe the effect of electroacupuncture on onset time and effectiveness of Paroxetine for mild or moderate depression patients and on the scores of Hamilton depression rating scale for depression(HAMD) and self-rating depression scale(SDS). Methods Fifty-five patients with mild or moderate depression were randomly divided into A group( Paroxetine group,29 patients) and B group (Electroacupuncture combining with Paroxetine group,26 patients). Therapeutic periods for the two groups were 6 weeks. HAMD and SDS were used to evaluate the efficacy before the research and after treatment on 1 week,2 weeks,4 weeks,6 weeks.Results HAMD scores and SDS scores for A group were significant difference after 2 weeks treatment compared with the beginning of the research (P＜ 0.05 ) ;HAMD scores and SDS scores for B group were significant difference after 1 week treatment compared with the beginning of the research(P＜0. 05 ). Total effective rate of HAMD for A group was 71.4% ,total effective rate of SDS for A group was 75% ,total effective rate of HAMD for B group was 88% ,total effective rate of SDS for B group was 84%. The total effective rate between the two groups ordered by the individual chi-square test was significant difference( X2 = 4. 1790, P= 0. 0408). Conclusion Electroacupuncture can shorten the onset time and increase the effectiveness of paroxetine for mild or moderate depression patients.

Objective To seek a new method to identify viability of myocardium by adenosine stress echocardiography combined with quantitative tissue velocity imaging(QTVI)and tissue tracking(TT).Methods Fifteen healthy canines were selected to establish the models of acute myocardial infarction and reperfusion by ligating anterior descending branch of coronary artery for 90 minutes and then releasing the artery to get reperfusion.After reperfusion.peak velocity in systole(Vs),peak velocity in isovolumic contraction(VIVC)and the displacement in systole(Ds)were measured on anterior wall and anterior septum at baseline.The 2,3,5-triphenyl tetrazolium chloride(TTC)staining was set as a"gold standard"for defining the viable and non-viable groups.The sensitivity and specificity of assessing myocardial viability were determined with QTVI and TT.Comparison of variables between viable and non-viable group was made by using t test.One way analysis of variance and LSD-t test were used to estimate the significance of differences in different states.Results Compared with baseline,Vs,VIVC and Ds decreased significantly(P＜0.01)after reperfusion in both viable and non-viable group.After administration of adenosine,Vs and Ds increased(P＜0.05),but VIVC didn't change significantly compared with that before administration of adenosine in viable group(P＞0.05).Variables in non-viable group didn't change significantly after administration of adenosine(P＞0.05).By receiver operating characteristic(ROC)analysis for predicting myocardial viability,when a cutoff value of △Vs(%)rate was 17.9,the sensitivity and the specificity was 78.6%and 81.1%,respectively,and when the cutoff value of △Ds(%)rate was 18.4,the sensitivity and the specificity was 75.0%,83.6%,respectively.Combined △Vs(%)with △Ds(%),the sensitivity and specificity to prediction of myocardium viability could reach 94.6%and 68.0%,respectively.Conclusions When the viability of myocardium after myocardial infarction is assessed by using the method of adenosine stress echocardiography with QTVI and TT,the sensitivity and the specificity are greatly enhanced.

Objective To observe the clinical efficacy and reverse reactions of acupuncture combined with paroxetine hydrochloride in the treatment of mild or moderate depression. Methods The patients with mild or moderate depression (n=73) were randomly divided into control group (treated with paroxetine hydrochloride,n=33) and observation group (treated with acupuncture and paroxetine hydrochloride,n=40). The therapeutic course lasted for 6 weeks. The total score changes of Hamilton Depression Scale (HAMD) were observed before treatment and treated for 1, 2, 4 and 6 weeks. Rating Scale for Side Effects (SERS) was evaluated before treatment and treated for 2, 4, 6 weeks.Results The total effective rate of clinical efficacy in the observation group was 78.95% (30/38) and the control group was 68.75% (22/32), without significant difference between the two groups (P>0.05). The scores of HAMD decreased 4, 6 weeks after the treatment in the control group and 2, 4, 6 week after the treatment in the observation group compared with those in the same group before the treatment (P<0.05,P<0.01). There was a significant difference in HAMD scores between two groups after the treatment for 4 weeks (P<0.05). The scores of SERS showed a significant difference 4, 6 weeks after the treatment between the two groups (P<0.05).Conclusion Acupuncture can improve the curative effect of paroxetine hydrochloride and decrease its side effects in the treatment of depression.

Recent studies have found that visfatin is involved in lipid metabolism in patients with nonalcoholic fatty liver disease (NAFLD), and about 25% of NAFLD patients have thyroid dysfunction. It has also been found that visfatin is involved in autoimmune regulation through the autocrine or paracrine pathways, which is associated with the involvement of the thyroid gland in autoimmune regulation of the body. This article preliminarily explores the association of visfatin with thyroid dysfunction in NAFLD patients and points out that the measurement of visfatin may help with the early identification of thyroid dysfunction in NAFLD patients.
