Thyroid nodules are common lesions which are over-treated in Mainland China. This article encourages using standard diagnostic procedures to differentiate malignant nodules from benign nodules especially by ifne needle aspiration (FNA) cytology. The proper treatment should be applied according to different FNA results to avoid overtreatment.

Objective:To investigate the diagnostic value of color Doppler flow imaging(CDFI) in the diagnosis of liver tumors.Methods: UE, CEUS, and CDFI were performed in 104 patients with liver cancer who were admitted to our hospital from January 2013 to December 2014, in order to analyze the diagnostic value of three methods for liver tumor compared with the pathological results.Results: The 115 masses of the group included 97 malignant masses(84.34%) and 18 benign masses(15.66%). The diagnostic accuracy of CDFI for benign and malignant liver tumors was 55.56% and 74.23%. There was no significant difference between UE and CDFI in the diagnosis of benign liver tumors and CEUS was higher than that of CDFI and UE in the diagnosis of benign and malignant liver tumors. There was no statistical difference in the diagnostic accuracy of CDFI combined with UE and CEUS(x2=2.20, P=0.138).Conclusion: CDFI is a basic method for the diagnosis of liver tumors. The CEUS or UE can be used to improve the accuracy of diagnosis for the liver which is not typical or small lesions.

Objective To investigate the characteristic and optimal therapy of critical limb ischemia (CLI) caused by limb arteriosclerosis obliterans (ASO) in elderly patients ≥70 years. Methods The clinical and follow-up data of 122 elderly patients (≥ 70 years) with CLI caused by ASO were analyzed. The differences were compared between 70-79 years patients (67 cases) and 80- 91 years patients (55 cases). Results The time from onset to treatment in 80-91 years patients was significant longer than that in 70-79 years patients:(45 ± 15) d vs. (26 ± 10) d, the ratios Rutherford class 4-6 and Trans-Atlantic Inter-Society Consensus (TASC) Ⅱclass C-D lesions in 80-91 years patients were significantly higher than those in 70-79 years patients: 89%(49/55) vs. 67%(45/67) and 91%(61/67) vs. 100%(55/55), and there were statistical differences (P<0.01 or<0.05). The ankle arm index (ABI) after endovascular treatment in 70-79 years patients (37 cases) and 80- 91 years patients (22 cases) were significantly higher than those before treatment: 0.86 ± 0.05 vs. 0.40 ± 0.05 and 0.85 ± 0.05 vs. 0.39 ± 0.08, and there were statistical differences (P<0.05). There were no statistical differences in ABI of conservative treatment patients before and after treatment (P>0.05). The conservative treatment mortality in 80- 91 years patients was significantly higher than that in 70- 79 years patients: 29%(7/24) vs. 9%(2/23), and there was statistical difference (P<0.05). Ninety-five patients were followed up for 1-24 months, and the median was 15 months. Nine patients (7%) died within 30 d. In the first year of follow-up, 8 cases underwent amputation, 6 cases died, and 6 cases had stent thrombosis. In the second year of follow-up, 12 cases underwent amputation, and 18 cases died. The median survival time was 19 months. The mortality in conservative treatment patients was significantly higher than that in endovascular treatment patients:53%(19/36) vs. 24%(14/59), and there was statistical difference (P<0.05). The survival time in amputation patients had increasing trend, but there was no statistical difference (P>0.05). Conclusions The≥70 years elderly patients with CLI caused by ASO have more complications and longer time from onset to treatment, and the lesions are mainly Rutherford class 4-6 and TASC classⅡC-D. Endovascular treatment is difficult, but the effect is better than conservative treatment.

Objective To evaluate the diagnostic value of combined test of C-reactive protein,amylase and lipase for acute pan-creatitis patients in early stage,and its practicability in assessment of disease severity.Methods 71 cases of acute pancreatitis pa-tients in the hospital from March 2012 to March 2014 were enrolled in the study,including 60 cases of mild pancreatitis patients,11 cases of severe pancreatitis patients.Meanwhile,30 cases of non-acute pancreatitis patients were enrolled as Control Group A,and 50 cases of adults who underwent conventional examination and proved to be healthy were enrolled as Control Group B.Detection of C-reactive protein,amylase and lipase of these samples were performed and the results were recorded,compared and analyzed.Re-sults The serum amylase level of acute pancreatitis patients was (759.42±721.63)U/L,and serum lipase level were (1 624.34± 1 598.25)U/L,which were significantly higher than people in Control Group A and Control Group B,with statistical significance (P <0.05).However,C-reactive protein level of acute pancreatitis patients were (44.61±34.21)mg/L,which were not statistical-ly different compared with Control Group B.Combined test of the three indicators demonstrated that the sensitivity was 95.9%, specificity was 100% and accuracy was 96.9%,all of which were higher than other test combinations or singe test with statistical significance(P <0.05 ).Conclusion The combined test of C-reactive protein,amylase and lipase for acute pancreatitis patients doesn′t only improve early diagnostic efficiency,but also is helpful in disease severity judgment.

Objective: To evaluate the therapeutic efficacy of acupuncture plus Chinese medicinal fumigation and washing in treating edema of the affected limb in post-stroke hemiplegia. ＜br> Methods: Two hundred patients with edema of the stroke-affected limb from our hospital were randomized into two groups according to their visiting sequence. In the observation group, 100 subjects were intervened by acupuncture plus Chinese medicinal fumigation and washing in addition to oral administration of diuretics, while the other 100 subjects in the control group were only given diuretics. The therapeutic efficacy was evaluated after successive 2-week treatments. ＜br> Results: The total effective rate was 90.0% in the observation group, significantly higher than 66.0% in the control group, indicating that there was a significant difference in comparing the overall therapeutic effect (P＜0.01). ＜br> Conclusion: Acupuncture plus Chinese medicinal fumigation and washing in addition to oral administration of diuretics is effective in treating edema of the affected limb in post-stroke hemiplegia.

Two different diets(high cholesterol and low protein) were used to induce gallstone formation in guinea pigs. After the guinea pigs had been fed on lithogenie diets for 8 weeks, the rate of gallstone formation was 100% in both groups. However, when ascorbic acid was added in the diets, the rate of gallstone formation was reduced to 16.7% and 52,9% respectively. The mechanism of gallstone formation was explored through observing the effect of animals diet change on gallstone formation and the effect of ascorbic acid on gallstone prevention. At the same time, the micro-structure observation and the component analysis of gallstone, the change of ultrastructure of the liver and gallbladder, and the quantitative analysis of conjugated bile acids of biles were condueted.

Objective To review the principles and techniques of CT perfusion imaging and its applications in the imaging diagnosis of abdominal disorders. Methods All the relevant literatures were reviewed. The principles and techniques of CT perfusion imaging were described and summarized in detail. The functional information of a target abdominal organ (e.g. the liver and pancreas) revealed by CT perfusion imaging, such as hemodynamics and microcirculation status, was also evaluated. Results In addition to the morphologic information, CT perfusion imaging can also provide functional information about the circulation parameters of target abdominal organs. Moreover, such functional information can be generated for the neovasculature and microcirculation of tumor lesions of abdominal organs, which is very helpful for not only the diagnosis, but also the evaluation of tumor invasiveness and response to treatment. Conclusion CT perfusion imaging offers an effective method for studying abdominal disorders by providing functional information that is quite useful for the differential diagnosis and assessment of therapeutic response.
