Chinese Journal of Diabetes 2015;(4):296-298
Objective To explore the risk factors of pregnancy complications in patients with gestationaldiabetesmellitus(GDM).Methods 134patientswithGDMweredividedintocontrolgroup without complication (n= 38) and complication group(n= 96).Serum fasting levels of glucose (FPG) , insulin ,lipid and C‐reactive protein (C‐RP) were measured. Both maternal and fetal complications of pregnancy were recorded. Results The levels of C‐RP ,FPG ,progestation BMI and lategestation BMI were significantly increased in complication group than in control group [(5.46 ± 4.20) vs (2.60 ± 2.76) mg/L ,(5.68 ± 1.36) vs (5.25 ± 0.77)mmol/L ,(24.79 ± 3.92) vs (23.03 ± 2.51)kg/m2 ,(29.05 ± 3.79) vs (27.25 ± 2.58)kg/m2 respectively ,P< 0.05].The C‐RP level is significantly associated with FPG.Logistic analysis showed that maternal complications were significantly related to lategestation BMI ,C‐RP , TC and HDL‐C.Infant complications were significantly related to C‐RP. Conclusion C‐RP ,lipid and late gestation BMI play important roles in the development of maternal‐neonatal complications during pregnancy. Keeping rational levels of glucose ,lipid and weight gain are helpful for improving pregnancy outcomes.
3.Application of contrast echocardiography in diagnosing cardiac tumors
International Journal of Biomedical Engineering 2013;(1):48-50,后插1
Echocardiography plays an important role in diagnosing cardiac tumors and is helpful for subsequent treatment decision making.However,conventional echocardiography can hardly meet the clinical requirements of sufficient diagnosis,mostly due to the fact that it usually does little on identification of benign and malignant characters of tumors.Contrast echocardiography is a new technology using microbubbles as a contrast agent to trace the blood flow,which promotes the definition of endocardium lines and helps to reveal spaceoccupying abnormities in heart.Moreover,myocardial contrast echocardiography can be used to evaluate perfusions of intracardiac masses,and thus improves the accuracy of differential diagnosis enormously.

Objective To compare the effects of different doses of amino acids and fat emulsions in parenteral nutrition on the incidence of complications and prognosis in very low birth weight infants (VLBWI). Methods The clinical data of 328 VLBWI who received nutrition support therapy for at least 5 days starting in 72 h after birth during January 2005 to December 2014 , were retrospectively analyzed. According to the dosage in parenteral nutrition, patients were divided into low-dose group and high-dose group. The incidence of complications and prognosis between two groups were compared. Results There were 204 cases in low-dose group and 124 cases in high-dose group. Compared with the low-dose group, the incidence of complications was lower in high-dose group during hospitalization and the incidence of intracranial hemorrhage was reduced most;the incidence of developmental retardation was lower at discharge;the overall incidence of metabolic complications of parenteral nutrition was higher, among which the incidence of high blood glucose, electrolyte disturbance and cholestasis were increased and the incidence of hypoglycemia was lower, and the differences were all statistically signiifcant (P?0 . 05 ). There was no difference in the incidences of hepatic lesion, hyperbilirubinemia, necrotizing enterocolitis and retinopathy of prematurity between two groups (P?>?0 . 05 ). Conclutsions VLBWI can tolerate early aggressive parenteral nutrition which can reduce the incidence of extrauterine growth retardation and premature complications.

During growth and progression, the microenvironment of tumors suffers a series of abnormal characteristics, which include hypoxia, acid pH, increased oxidative stress, excess glutathione (GSH), as well as certain overexpressed enzymes. Although affect or limit the cancer therapeutic outcomes, these factors provide possible approaches to strategies for cancer detection and novel therapy at the same time. Recently, based on these properties of the tumor microenvironment (TME), various kinds of responsive nano-platforms have been continuously developed and applied in cancer theranostics preliminarily. Thus, this review would introduce the typical features of TME firstly, then detailly summarize the design principles and research progress of corresponding hypoxia-responsive, pH-responsive, redox-responsive, enzyme-responsive, dual-responsive and multi-responsive nano-platforms. Finally, the challenges and the perspectives of the TME-responsive nano-platforms are briefly discussed.

Objective To evaluate the clinical value of double-balloon enteroscopy( DBE)in as-sessing the effect of mucosal healing in patients with moderate small bowel Crohn's disease( CD)treated with low-dose azathioprine. Methods CD patients who were naive to any immunomodulators or biological a-gents with lesions mainly located in ileu were screened by multislice CT enterography and anal-route DBE at baseline. Lesions at 150 cm proximal to ileocecal valve were assessed by DBE with Simple Endoscopic Score for CD( SES-CD)after 12 and 24 months of low-dose azathioprine treatment,respectively. Results A total of 36 patients were enrolled and the average tolerated dose of azathioprine was(61. 8 ± 17. 2)mg/day. The total rates of complete,near-complete,partial and no mucosal healing in 36 patients were 19. 4%(7/36), 5. 6%(2/36),27. 8%(10/36),and 47. 2%(17/36)at month 12 and 30. 6%(11/36),25. 0%(9/36), 33. 3%(12/36),and 11. 1%(4/36)at month 24,respectively. The baseline SES-CD score(OR=2. 71, 95%CI:1. 11-6. 63,P=0. 029)and duration of disease(OR=1. 27,95%CI:1. 10-1. 47,P =0. 001) were two relevant factors associated with mucosal healing of small bowel CD. Conclusion DBE has a signif-icant advantage in assessing post-therapy mucosal healing for patients with small bowel CD. The optimal time point for the first follow-up by DBE is at least 12 months after low-dose azathioprine treatment.
