The efficacy of colorectal cancer treatment is not very satisfactory.Conventional morphologic imagings are limited in the diagnosis and in the applications of multimodality treatment for colorectal cancer.18 F-fluorodeoxyglucose PET-CT can play a pivotal role in detecting metabolism changes and in the localization of lesions concurrently.It is valuable in the assessment of responses to therapy,prediction of prognosis and selecting modality management and monitoring postoperative recurrence.The right-moment and proper application of PET-CT can increase the therapeutic efficacy of colorectal cancer.

Cardiovascular diseases, like coronary heart disease and myocardial infarction, are the most common cause of death worldwide. Chinese medicines have demonstrated rich cardioprotective activities for clinical applications. Salvia miltiorrhiza, a very important component of traditional Chinese medicine, can promote blood circulation and relieve blood stasis. Salvia miltiorrhiza is widely used in treatment of cardiovascular and cerebrovascular disease such as coronary heart disease and cerebral infarction ( CI). Tanshinone II(A), the major lipophilic components extracted from the root of S. miltiorrhiza, possesses anti-atherosclerosis, anti-cardiac hypertrophy, anti-oxidant, anti-arrhythmia and so on. This paper discusses current research status of tanshinone II(A) in cardioprotective effects.

AIM:To investigate the renal function and pathological changes in Npc1 mutant ( Npc1-/-) mice. METHODS:Different genotypes of Niemann-Pick disease type C1 (Npc1) mice were identified by PCR.Subsequently, the renal function of Npc1-/-and Npc1 +/+mice at postnatal day 60 ( P60) was evaluated by measuring the activity and con-tent of important indicators in the serum including ALT , AST, LDH, urea, UA and Cr.Furthermore,β-galactosidase stai-ning and Masson staining were performed to examine the aging and fibrosis of the renal tissues , respectively .RESULTS:Compared with the Npc1 +/+mice, the body weight and kidney weight had a significant reduction ( P<0.01) in the Npc1-/-mice.The results of hepatic and renal functions showed that the activities of ALT , AST and LDH, and contents of urea, UA and Cr had marked increases (P<0.05) in the Npc1-/-mice.Moreover, the results of senescence-associatedβ-galacto-sidase staining in the renal tissues demonstrated accelerated aging in the Npc1-/-mice (P<0.01), and these results were confirmed by Masson staining, which clearly showed the formation of collagen fibers (P<0.01).CONCLUSION:Muta-tion of the Npc1 gene results in abnormal lipid metabolism , which accelerates kidney senescence by promoting fibrosis in the renal tissue and subsequently causes reduction in renal function .

0.05)and 1.464(95% CI 1.061- 2.020,P=0.02),respectively in hemorrhagic stroke patients after adjustment for age,gender,ethnieity,cigarette smoking and alcohol drinking.However,the ORs of mortality and morbidity were not significant in various pulse pressure groups in ischemic stroke patients.Conclusion The elevated pulse pressure was associated with increased risk of in-hospital morbidity only in hemorrhagic stroke patients.

Objective To investigate the differentiatial diagnostic value of 99Tcm-methoxyisobutylisonitrile ( MIBI ) SPECT combined with localizable CT in the evaluation of oxygen intervention for suspicious lung lesions,and to establish a cost-effective imaging modality in the detection of malignant lung lesions.Methods From September 2008 to March 2009,47 consecutive patients with suspicious malignant lung lesions underwent 99Tcm-MIBI SPECT/CT prospectively. Patients with suspicious pneumonia were treated with antibiotics for about 4 d before imaging. All patients were cannulized with a nostril tube for oxygen inhalation before 99Tc-MIBI injection. SPECT combined with localizable CT of the chest was performed at 10 min and 2 h after 99Tcm-MIBI injection. The uptake ratios of lesion to contralateral normal lung parenchyma(early uptake ratio:EUR and delayed uptake ratio:DUR) were compared using independent-samples ttest. In addition,the diagnostic efficiency of uptake ratios of lung lesions was analyzed with receiver operating characteristic (ROC) curve. Results Forty-seven patients ( primary lung cancers:32,metastatic tumors of the lung:4,benign lung diseases:11 ) had 51 lung lesions,including 39 malignant and 12 benign lung lesions. The sensitivity,specificity,accuracy,positive predictive value (PPV),and negative predictive value (NPV) were 94.9% (37/39),83.3% ( 10/12),92.2% (47/51),94.9% (37/39) and 83.3% ( 10/12),respectively. The EUR of malignant lesions was 2.95 ± 1.16,whereas of benign lesions was 1.43 ±0.33. The DUR of the malignant lesions was 3.19 ± 1.74,whereas of benign lesions was 1.60 ±0.32. Both EUR and DUR were significantly different between malignant and benign lung lesions,respectively (t= -4.44,-3.12,respectively,both P＜0.01). The ROC curve showed that EUR value ≥1.625 provided the sensitivity of 97.4% (38/39) and specificity of 83.3% (10/12); DUR value ≥ 1.75provided the sensitivity of 94.9% (37/39) and specificity of 83.3% (10/12). Conclusion 99Tcm-MIBI SPECT combined with localizable CT imaging in oxygen intervention has a potential value in differentiating malignant from benign lung lesions.

?AlM:To observe the clinical effect of the intravitreal Ranibizumab ( lVR ) combined with retinal photocoagulation for the neovascular glaucoma ( NVG) .
? METHODS: Clinical data of 30 patients with the neovascular glaucoma ( 36 eyes ) in our hospital from Ocuober 2012 to Sepember 2013 were analyzed retrospectively. All eyes accepted the photocoagulation 7d after lVR (0. 05mL/1. 25mg). Visual acuity, intraocular pressure ( lOP) , the degradation of iris neovascularization and complications were observed and compared statistically before treatment and 1wk, 1, 3mo after treatment.
?RESULTS:The new vessels on the iris and the angle of anterior chamber regressed completely in all eyes 5d after lVR, the mean time was 3. 7±1. 4d. The differences were statistically significant when compared lOP ( 18. 2±2. 1, 16. 8 ± 3. 1, 17. 2 ± 2. 4mmHg,) at 1wk, 1, 3mo postoperatively with 30. 5±3. 6mmHg preoperatively. The visual acuity of all the eyes was stable and rose slightly.
? CONCLUSlON: lVB combined with retinal photocoagulation can make the new vessels on the iris and the angle of anterior chamber regression and to lower the lOP. No serious complications were observed after treatment. lt is a new security and effective method for neovascular glaucoma.
