BACKGROUND:Coenzyme Q10 participates in the electron transport of respiratory chain and possesses antioxidant, anti-apoptotic and anti-inflammatory properties. It has achieved good outcomes in cardiovascular disease, diabetes and cancer. Coenzyme Q10 may also have a certain application value in the fields of diabetes and periodontitis. OBJECTIVE:To observe the effect of coenzyme Q10 on the expression of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis.METHODS:Forty-eight healthy male Wistar rats were randomly divided into 3 groups: control, periodontitis+ diabetes+physiological saline and periodontitis+diabetes+coenzyme Q10. Rats in the control group were fed with normal diet and water. Rats in the periodontitis+diabetes+physiological saline and periodontitis+diabetes+ coenzyme Q10 groups were subjected to induction of periodontitis using the method of silk ligation and type 2 diabetes by feeding a high-fat and high-sugar diet and intraperitoneal injection of streptozotocin. After successful modeling, rats in the periodontitis+diabetes+coenzyme Q10 group were intragastricaly administered coenzyme Q10 for 8 successive weeks. Rats in the periodontitis+diabetes+physiological saline group were administered equal amount of physiological saline. At the end of 2nd, 4th and 8th weeks after drug administration, four rats were randomly selected and sacrificed. The expression levels of interleukin-17 and interleukin-23 in gingival tissue were detected by immunohistochemistry. RESULTS AND CONCLUSION: At the end of 8th week, interleukin-17- and interleukin-23-positive expression in the periodontitis+diabetes+physiological saline group was significantly higher than that in the periodontitis+ diabetes+coenzyme Q10 group (P < 0.05). Coenzyme Q10 can reduce the expression levels of interleukin-17 and interleukin-23 in gingival tissue of type 2 diabetic rats with periodontitis, and aleviate periodontal tissue inflammation of type 2 diabetic rats with periodontitis.

Methods Hepatic metastasis models were established by injecting Lovo cells into the spleen of SD rats.This study was divided into control group, microbubble plus ultrasound radiation group simple contrast agent group and simple ultrasound radiation group.Ultrasound contrast agent SonoVue(1 ml/kg) was injected via tail vein, high mechanical index ultrasound contrast (frequency 1.5 MHz,MI 1.7) was performed intermittently for 2 min.After 10 d,the animals were killed and the size and number of hepatic metastasis were compared.Histological pathology and its ultrastructure were observed.Results There were no significant differences between contral group,simple ultrasound radiation group and simple contrast agent group in metastatic rate ( P＞0.05).There were no obvious differences between contral group, simple ultrasound radiation group and simple contrast agent group in cells'ultrastructure by transmission electron microscopy (TEM).The number and size of hepatic metastasis decreased obviously in microbabble plus ultrasound radiation group ( P＜0.01 ), the mitochondrion was swelling and the gaps of endothelial cells were loose. Conclusions High mechanical index ultrasound contrast can inhibit the hepatic metastasis of colorectal cancer.

This study examined the promoter methylation of APO-1/CD95 (Fas) gene in bladder urothelial carcinoma and analyzed the relationship between the Fas promoter methylation and the biological behavior of bladder cancer. Promoter methylation of Fas gene was detected by methylation-specific PCR (MSP) in 4 bladder cancer cell lines, 50 human bladder urothelial carcinoma samples and l0 normal bladder tissue samples. Correlation of the aberrant methylation of Fas promoter with the clinicopathological parameters was statistically analyzed. The results showed that Fas was down-regulated at both mRNA and protein level in bladder cancer cell lines and tissue samples of bladder urothelial carcinoma. The positive rate of Fas protein expression in bladder urothelial carcinoma was 34.0% (17/50), significantly lower than that in normal bladder tissues (70.0%, 7/10) (P<0.01). Fas promoter methylation was detected, and the positive rate of Fas promoter methylation in bladder urothelial carcinoma was 42.0% (21/50), which was obviously higher than that in normal bladder tissues (0.0%, 0/10) (P<0.01). The aberrant methylation of Fas promoter was reversely correlated with Fas protein expression (P<0.05). Furthermore, the positive rates of Fas promoter methylation in high-grade and low-grade bladder urothelial carcinoma were 73.3% (11/15) and 34.2% (12/35), respectively, with significant difference shown (P<0.05). No statistical significance was found in the Fas promoter methylation among different clinical stages of bladder cancer. It was concluded that Fas promoter hypermethylation plays an important role in the pathogenesis of bladder urothelial carcinoma and may serve as a prognostic indicator of bladder urothelial carcinoma.

Objective By analyzing the changes in behavior and the myelin basic protein (MBP) of the offspring in adult that treated with Poly(I∶C) during pregnancy,and to understand the role of white matter abnormalities in the abnormal behavior of the offspring induced by infection in maternal hosts.Methods Two models maternal female rats were given Poly(I∶ C) with 5 mg/kg and 10mg/kg respectively during the early pregnancy,and control maternal female rats was administered 5 mg/kg saline.The prepulse inhibition test,passive avoidance test and active avoidance test were used to evaluate schizophrenia like behaviors for each groups offspring in 8 weeks,and the expression of MBP was detected by immunohistochemical staining methods.Results The results of prepulse inhibition test showed that significant differences of PP2,PP4 and PP8 results existed among control group,single-dose model group and double-dose model group (F=10.381,P=0.001,F=10.313,P=0.001,F=15.233,P=0.000).Compared with the control group,the two model groups showed significantly lower,the double-dose model group was lower than single-dose model group (P＜0.05).In passive avoidance test,there were significant differences of T1 and T2 results existed among control group,single-dose model group and double-dose model group (F=23.555,P=0.000,F=17.524,P=0.000).The T1 results of two model groups were significantly higher than control group,the double-dose model group was significantly higher than single-dose model group (P＜0.05) ; the T2 results of two model groups were lower than control group,the double-dose model group was lower than single-dose model group(P＜0.05).The results of passive avoidance test indicated that significant differences existed among control group,single-dose model group and double-dose model group in whole period of testing and total conditioned response rate(F=8.631,P=0.000,F=6.986,P=0.001),the two model groups were significantly lower than control group,double-dose model group was significantly lower than single-dose model group (P＜0.05).MBP results of two model groups were significantly lower than control group,two model groups had no significant difference (P＞ 0.05).Conclusion The adult offspring that were treated with Poly (I∶C) exit abnormal behavior and damaged white matter,and there is a correlation between the degree of abnormal behavior and drug dose.

Objective To explore the application value of Carbon Nanoparticles followed by microscale Methylthioninum Chloride in sentinel lymph node biopsy for breast cancer.Methods Two hundred and eight breast cancer patients were selected in the First Affiliated Hospital of Zhengzhou University during recent two years who performed sentinel lymph node biopsy.They were randomly divided into five groups according to different lymphatic tracer injected:Sequential group (A group,128 patients),Carbon Nanoparticles group (B group,44 patients) and Methylthioninum Chloride group (C group,36 patients).According to different Methylthioninum Chloride doses,sequential groups were randomly divided into low dose group (A1 group,48 patients),middle dose group (A2 group,42 patients),high dose group (A3 group,38 patients),If sentinel lymph nodes were negative no longer performed axillary lymph nodes dissection.Receive the five groups statistics of detection rate,the condition of lymphatic tracer,the incidence of local skin irritation and so on.Results (1) The detection rate of A,B and C three groups had no obvious difference.The incidence of lymphatic tracer dyed not ideal in B group was higher than A and B two groups,the incidence of local skin stimulation in C group was higher than A and B two groups.(2) A1,A2,A3,three groups had no difference of the detection rate and lymphatic tracer,but the incidence of local skin stimulation in A3 group is higher than A1,A2 two groups.3.5 groups of SLN detection rate had no relationship with patients' age,BMI,tumor size,tumor location,tumor molecular classification factors (P ＞ 0.05).Conclusions Carbon Nanoparticles followed by microscale Methyhhioninum Chloride detection rate was similar with two separate application,but can reduce the lymphatic vessels not developing situation when used Carbon Nanoparticles alone and reduce the local irritation caused by large dose of Methylthioninum Chloride,so it can be a good choice of SLNB in clinical.
