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.

Objective To investigate the distribution,epidemiologic features and antibiotic resistance of the enteric pathogens i-solated from children with diarrhea.Methods Enteric pathogens were isolated from children’s stool samples.The children with diarrhea were treated in the outpatient and inpatient of Shanghai Children’s Hospital between 2008 and 2013.Antimicrobial susceptibility testing was conducted by disk diffusion method for Salmonella and Shigella with 6 antimicrobial agents.Results A total of 545 enteric pathogens were collected.Salmonella was the dominant pathogen,accounting for 67.2%,followed by Shigella (20.7%),S.aureus (4.6%),C.jejuni (3.7%),Aeromonas (2.4%),and enteropathogenic E.coli (0.9%).The main serotypes of Salmonella were S.typhimurium and S.enteritidis.Approximately 56.3% of the patients were boys.A-bout 72.7% of the patients were infants under 2 years.The prevalence of diarrhea peaked in summer and autumn (72.9%). The susceptibility of these isolates was only tested with seven antibiotics.Shigella showed higher level of resistance to ampicil-lin and trimethoprim-sulfamethoxazole than Salmonella (P<0.05).Significantly higher percentage of S.flexneri isolates were resistant to sulbactam-ampicillin,ceftriaxone,ciprofloxacin,and chloramphenicol than S.sonnei (P<0.001).Further-more,the prevalence of multidrug resistant strains in Shigella (68.3%)was much higher than that in Salmonella (44.7%,P<0.001).Conclusions A variety of diarrhea-causing enteric pathogens are isolated from the children in Shanghai Children’s Hospital.The isolates are predominantly Salmonella and Shigella species.The epidemiological features of Salmonella and Shigella species are different in terms of gender,age,season and geographical distribution.The resistance to antibiotics is a serious problem and varies with different types of pathogens. Intensive and ongoing surveillance of enteric pathogens and their changing resistant pattern is required to control diar-rhea in children.
