Proteomics is a new research area of the post-genomic era. Oncoproteomics is an important branch of it.Here we discuss the investigative outcome of thyroid oncoproteomics in recent years,such as specific tumor biomarkers and antineoplastic drug.

Objective　To improve the recognition of the imaging appearances of inflammatory pseudotumors of the spleen (IPS), 3 cases with IPS were reported. Methods　The US (n=3), CT (n=3) and MRI (n=1) findings of IPS were reviewed and correlated with the pathologic findings. Results　On US, a well-defined solitary mass with heterogeneous echo texture was found in all 3 cases. A hyperechoic rim with associated acoustic shadowing was shown in 1 case. In all of the 3 cases in nonenhanced CT scanning, a well-defined hypoattenuated mass was found. One had a calcified egg-shell-like rim; On the venous/delayed phase of enhanced CT after contrast administration in 2 cases, slight/marked enhancement was shown. On nonenhanced MRI in 1 case, the mass was shown as heterogeneous hypointensity on T1- and T2- weighted images. Conclusion　IPS should be included in the differented diagnosis of solitary mass lesion of spleen. The imaging findings depend on the variable proportions of fibrous and granulomatous components within the lesion. IPS was characterized by well-defined solitary mass on sonogram, delayed enhancement on enhanced CT, and hypointensity on T2 weighted MR images.

ObjectiveTo investigate and eveluate the significance of serum and urinary L-selectin in patients with transitional cell carcinoma.MethodsSerum and urinary samples were obtained before operation and 6 days after surgery from 46 patients with transitional cell carcinoma of bladder and from 14 patients with benign prostate hyperplasia.The serum and urinary L-selectin levels were measured using ELISA.ResultsThe preoperative serum concentration of L-selectin was significantly higher in patients with invasive bladder cancer [(766.3?135.1)ng/ml] than those with superficial bladder cancer [(563.8?118.2)ng/ml],P

Objective: To study the correlation of blood stasis syndrome or its accompanied syndromes with Gensini score in patients with coronary heart disease (CHD) in stable condition. Methods: The syndrome types of traditional Chinese medicine (TCM) and blood stasis score in 131 CHD patients confirmed by coronary angiography were recorded. Gensini score was calculated according to the coronary pathological characteristics showed by angiography. The correlations of blood stasis syndrome and its accompanied syndromes with coronary lesion and Gensini score were analyzed. Results: Among the TCM syndrome types, blood stasis, turbid phlegm and qi deficiency were the most common syndromes, revealed in 85 patients (64.9%), 83 patients (63.4%) and 85 patients (64.9%), respectively. The coronary lesion length and Gensini score in the patients with blood stasis syndrome were much higher than those in the patients with non-blood stasis syndrome (P<0.05 or P<0.01). In the subtypes of blood stasis, the coronary lesion length and Gensini score in the patients with blood stasis accompanied by turbid phlegm syndrome were higher than those in the patients with non-blood stasis syndrome (P<0.05). And in the patients whose blood stasis syndrome score was more than 9 points, the coronary lesion length was higher than that in the patients whose blood stasis syndrome score was less than 9 points (P<0.05). Besides, with bivariate analysis, the blood stasis syndrome score showed no correlation with Gensini score (Pearson correlation coefficient was 0.104, P=0.241). Conclusion: Blood stasis syndrome is the most common TCM syndrome in CHD patients in stable condition. The blood stasis syndrome score is proportional to coronary lesion length, and reflects the severity of coronary lesion.

0bjective To summarize the experience of postoperative and mid-term echocardiographic evaluation of modified Blalock-Tasussig(BT)shunts. Methods During 2003-2006,thirty five consecutive patients received modified BT shunts and survived postoperative 6 months were enrolled in this study.Transthoracic echocardiography was utilized to evaluate the patency of shunts and the change of pulmonaryarteries(PA)and left ventricle(LV). Results Three patients received the emergence surgery for the intervention for the BT shunts. The follow-up was (21.2±11.3) months. During the follow up,the obstruction of shunts occurred in 7 cases. After the placement of shunts,the mean size of PA increased by 31.2%,meanwhile,the size of LV increased by 25.6%. Nineteen patients received the followed definitive repair or palliative operations. Compared with the patients still waiting for the growth of PA,the patients who receiving the second staged procedure achieved the more appropriate PA growth. Furthermore,for the above patients,there was no significant difference between the angiographic and echocardiographic evaluation for the PA size. Conclusions Echocardiography could accurately diagnose the patency of shunts and record the growth of PA and LV following BT shunts. Echocardiography is a highly reliable noninvasive approach for the perioperative evaluation and mid-term follow-up for the modified BT shunts.

Objective To investigate the feasibility of reducing the radiation dose in adult pelvic CT using automatic tube current modulation (ATCM) and adaptive statistical iterative reconstruction (ASIR).Methods Totally 45 patients who underwent routine and low-dose pelvic CT examination were enrolled in our study.Three groups of images were acquired:group A (routine scan with FBP reconstruction) ;group B1 (low-dose with ASIR0) and group B2 (low-dose with ASIR50％).The scores of image quality was abtained by two radiologists.Results The CTDIvol,DLP and E of group B were significantly reduced respectively(t =12.30,12.10,12.15,P ＜ 0.05) compared with group A.Group B1 had higher noise(t =9.14,8.95,P ＜ 0.05)and lower score,SNR and CNR(t =8.72,10.62,11.83 and 8.40,9.55,11.42,P ＜ 0.05) than the others.And there was no difference in image quality between group A and group B2.Conclusions Using automatic tube current modulation and adaptive statistical iterative reconstruction could significantly reduce the noise but keep the image quality in adult pelvic CT examination.

OBJECTIVE:To provide a reference for reducing adverse events due to off-label use of drugs and promoting ratio-nal use of intravenous drugs in Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine. METHODS:The pre-scriptions of intravenous drugs in 42 wards of our hospital from Jul. 2013 to Jun. 2014 were reviewed,and then off-label use of drugs were analyzed,where statistics was made mainly to drug overdose,the use of drugs at the concentration beyond the standards (including concentrations too high and too low) and associated conditions. RESULTS:There were 622 irrational prescriptions,in-cluding 60 concerning off-label use of drugs,accounting for 9.6% of irrational prescriptions,in which 40 were involved with the concentration which was too high,accounting for the highest percentage(66.7% of prescriptions related to off-label use of drugs), 17 were related to drug overdose(28.3% thereof),and 3 were in relation to the concentration which was too low(5.0% thereof). CONCLUSIONS:Pharmacy intravenous admixture service may,through the communication between the pharmacist and the doc-tor,refuse to make up the above-mentioned prescription which was found to be irrational(including that involving in off-label use of drugs)or make up such prescription after it is modified according to the requirements as specified in the label to reduce the occur-rence of off-label use of drugs so as to promote rational drug use.
