Chinese Journal of General Surgery 2008;23(6):447-449
Objective To observe the effects of aspirin on PCNA and cyclin D1 expressions in diethylnitrosamine (DEN) induced hepatic cancer of the rat. Methods Sprague-Dawley (SD) rats were randomly divided into DEN group and DEN plus aspirin group. Each group was further divided into 8,12,16 week subgroups. The expressions of PCNA and cyclin D1 in hepatic tissue were examined with inmunohistochemistry. Results In DEN plus aspirin group cirrhosis was less severe and carcinoma developed later than that in DEN group. Hepatic carcinoma occurred in four rats out of six in DEN group at the 16th week (P<0.05). In DEN plus aspirin group PCNA and cyclin D1 expressions were significantly lower than those in DEN group(P <0.05) , inhibiting effects on cyclin D1 expression was evidently great at 16th week (F=11.944,P<0.05) and inhibiting effect on PCNA was obvious from 12th to 16th week (F=5.696 and F=11.057, P<0.05 ). Conclusion Aspirin downregulates the expressions of PCNA and cyclin D1 in hepatic tissues and inhibits the genesis and development of DEN induced hepatic cancer of the rats.

Objective To investigate characteristics of deceleration capacity (DC) and Tp-e/QT value in different age groups of patients with diabetic autonomic neuropathy, and to analyze their influencing factors. Methods A total of 487 subjects were enrolled in this study, and divided into three groups:patients with diabetic autonomic neuropathy (DM+CAN group,n=287), normal glucose tolerance patients with diabetic autonomic neuropathy (CAN group,n=130) and healthy controls (NC group,n=150).Then the DM+CAN group were further divided into three subgroups according to age tertiles:the lowest tertile group (35.0~47.2 years old,n=91),the middle tertile group (47.3~59.6 years old,n=116)and the highest tertile group (59.7~72.0 years old,n=80).All subjects were underwent 24-hour dynamic electrocardiogram recordings.DC and Tp-e/QT values were calculated,and then the correlation between DC and Tp-e/QT with other indicators was analyzed. Results The levels of WC,SBP,BMI,FPG,HbA1c,FIns and HOMA-IR were higher in DM+CAN group than in CAN group and in NC group (P<0.05 or P<0.01).DC increased and Tp-e/QT decreased from DM+CAN group,CAN group to NC group,and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).DM duration,WC,FPG,FIns,HbA1c,HOMA-IR,hypertension and CHD ratio were higher in the highest tertile group and middle tertile group than in the lowest tertile group (P<0.05 or P<0.01).DM duration and FIns were higher in the highest tertile group than in middle tertile group (P<0.05 or P<0.01).RHR and AHR were lower in the highest tertile group than in the lowest tertile group (P<0.05),and there were no statistical significant difference between the middle tertile group and the lowest tertile group (P>0.05).DC increased [(2.90±0.47) vs (4.22±0.41) vs (4.97±0.35) ms],and the Tp-e/QT decreased [(0.23±0.05) vs (0.18±0.03) vs (0.12±0.02)] from the highest tertile group to the lowest tertile group,(P<0.05 or P<0.01),and the pairwise comparisons were statistically significant (P<0.05 or P<0.01).Multiple stepwise regression analysis showed that age,DM duration,WC,FPG,HbA1c,complicated with hypertension and coronary heart disease (CHD) were risk factors for DC and Tp-e/QT values (P<0.05). Conclusion Together with the increased age,DC level is reduced and Tp-e/QT value increased in patients with diabetic autonomic neuropathy.Dynamic electrocardiogram should be considered in patients with advanced age,long DM duration,high level of WC,FPG,HbA1c,and complicated with hypertension and CHD,in order to prevent the occurrence of cardiovascular events effectively.

Objective To introduce an improved technique of periareolar incision mammoplasty using gland flap suspending and contour line circum-contraction suturing. Methods Through the periareolar incision, dissection was conducted between the subcutaneous tissue and the glandular tissue to detach the skin flap tent from the gland cone. A vertical glandular flap was formed in the upper portion to suspend the gland, with the gland tissue partially excised medial and lateral to the vertical glandular flap. Continuous contour line circum-contraction suturing was made for 2~3 rounds step by step from the cone bottom to the plateau, i.e. the nipple areola level. The suturing proceeded alternately from the flap tent to the glandular cone. Finally, the skin was sutured along the areolar incision. Results Sixteen breasts of eight patients were operated on using the present technique, including 10 cases of macromastia and 6 of breast ptosis. Satisfactory results were achieved with pretty breast shape and inconspicuous periareolar scar. Conclusion The contour line circum-contraction suturing periareolar incision mammoplasty is an optimal choice for moderate macromastia and breast ptosis.

Based on the associated theory of spleen-kidney deficiency about the traditional Chinese medicine and experimental research to discuss myasthenia gravis treated by integrative medicine.According to the theory of traditional Chinese medicine,the mechanism of myasthenia gravis is Qi deficiency of the spleen-stomach.Experimental studies showed supplementing spleen and kidney can improve ATP,muscle glycogen,fat content,other molecular biology material foundations,skeletal muscle cells under hypoxia and mitochondrial structure of animal models and patients,and therefore treat the deficiency of both spleen and kidney.

Objective This study aimed to identify high?risk groups for metabolic syndrome(MS)among Chinese children and adolescents by calculating the cutoff values of adiposity measures and insulin resistance(IR). Methods From December 2010 to January 2011,data from 933 Chinese subjects(492 boys and 436 girls,aged 11?16 years)from Liaoyang City,China,were included. Questionnaires were administered,and da?ta such as anthropometric parameters(height,waist circumference,and hip circumference),blood pressure,fasting blood glucose level,blood lip?id level,serum uric acid level,and fasting insulin level were collected. Receiver?operating characteristic(ROC)curve analysis was used to deter?mine the optimal cutoff waist?to?height ratio(WHtR),waist?to?hip ratio(WHR),homeostasis model assessment?insulin resistance(HOMA?IR) index,triglyceride level,glucose index(TyG index),and serum uric acid(SUA)level for identification of children and adolescents with MS. Results The AUC of WHtR,WHR,TyG index,HOMA?IR index,and SUA level were larger than 0.5,with P values of<0.01. The optimal cutoff WHtR and WHR derived from the ROC analysis were respectively 0.48(87.0%,84.1%)and 0.84(83.3%,70.3%)for boys and 0.46(95.1%, 81.8%)and 0.80(90.5%,71.8%)for girls. Conclusion This study demonstrated that WHtR and WHR are useful predictive markers of MS , while HOMA?IR,TyG index,and SUA level are not. The usefulness of these criteria needs to be verified by further evaluation.
