International Journal of Surgery 2014;41(12):834-836
Objective To establish a mouse model of heterotopic heart transplantation and construct an animal model for the study of transplantation immunity.Methods According to the surgical procedures of Ono's pattern in mice cardiac heterotopic transplantation model,50 Kunming mice were divided into donors and recipients randomly.The donor heart aorta and the recipient ventral aorta,the donor pulmonary artery and the recipient inferior caval vein,were anastomosed by using the end-to-side suture technique respectively.Results The mouse model of heterotopic heart transplantation was established successfully with a success rate of 84% (21/25).The average time of donor operation and recipient operation was (11.0 ± 1.0) min and(60.0 ± 2.0) min respectively.Conclusions In the base of mastering the technique of operation facility,the model of mice heart heterotopic transplantation would be established successfully.

Objective To search for a simple and rapid skin expansion. Methods CCPSEPA-A kind of mutual feedback type continuous normal saline perfusion system was assembled with the use of conventional transfusi on apparatus, sphygmomanometer, three-way stopcocks, plasma bag etc.14 cases ( 17 expanders) were carried out with such a device, controlled by patients themselves. Results The volume of expanders was 50~300 ml and the duration of expansion was 7~14 days. All the cases proved a wonderful effect that the expansion was finished by only one or two times of water filling of storage water bag, and without any complications.Conclusion CCPSEPA is a new skin expansion apparatus of new type and practical ,simple and low price .The general goal of safe,simple, rapid and useful was realized basically by the device,and worth popularizing.

Clinical Medicine of China 2015;(4):329-331
Objective To investigate the diagnostic value of CT virtual endoscopy on the small intestine (CTVE)technology for intestinal diseases. Methods Forty-nine cases with suspected small bowel disease were tested by CTVE from December 2010 to February 2014. They also were performed. Results Of 49 patients, operation or electronic endoscopy showed that 9 cases were benign tumors,29 cases with malignant tumors,3 cases with intestinal polyps,4 cases with intestinal inflammation,2 cases with bowel dysfunction and 2 cases with normal intestinal. CTVE test showed that 11 cases were with benign tumors,29 cases with malignant tumors,2 cases with intestinal inflammation,1 case with intestinal polyps,4 cases with intestinal dysfunction and 2 cases with normal small intestine. Better consistency between the two diagnosis was seen(Kappa = 0. 70). The accurate rate of diagnosis was 85. 71%(42 / 49). The correct rate of CTVE diagnosis of space occupying lesions was 90. 24%(37 / 41). The correct rate of non occupied lesions was 50. 00%(3 / 6). Conclusion CTVE technology has the advantages of simple operation,safe,painless,and clinical diagnosis of small bowel disease rate is higher especially for small bowel accounted disease. It is worthy of clinical application.

Quercetin and praziquantel were used to treat mice with hepatic fibrosis due to Schistosoma japonicum infection.Quercetin treatment obviously relieved the degree of hepatic fibrosis,significantly reduced the expression of immediate early gene,tissue inhibitor of metalloproteinase 1(TIMP 1),typesⅠ and Ⅲ collagen compared to the control.The expression of c-jun mRNA,typeⅠ and type Ⅲ collagen were reduced significantly compared to the group treated with praziquantel,whereas no difference in the expression of c-fos mRNA and TIMP1 between the two groups,indicating that quercetin may have better effect on schistosomal liver fibrosis than praziquantel in the long term.

Objective To study the chitin enzyme protein(YKL-40),sCD40L,AFP and the correlation of hypertension with cor-onary heart disease(CHD).Methods 75 cases of elderly patients with CHD were selected as observation group,and then were di-vided into hypertension group and non hypertension group according to the blood pressure.103 cases of healthy elderly were select-ed as control group.ELISA method was used to detect YKL-40 and sCD40L,and AFP was detected by chemiluminescence immuno-assay.Results Clinical data comparison revealed that the relative risk of CHD with hypertension group and non hypertension of hy-perlipidemia,drinking,smoking,diabetes mellitus,were 1.56,1.33,1.23,1.15 times,data show that relative risk of CHD with hy-pertension were much greater than CHD without hyperlipidemia.The concentration of YKL-40 in CHD with hypertension(92.66± 12.04)ng/mL was significant higher than that in CHD without hypertension (57.08 ± 10.07 )ng/mL,and the concentration of sCD40L in CHD with hypertension (186.59 ± 69.63 )ng/mL was significant higher than that in CHD without hypertension (128.14±48.37)ng/mL(P <0.05).There was no significant difference in the concentration of AFP in patients with CHD with hy-pertension and non hypertension(P >0.05).Conclusion The levels of YKL-40,CD40L and AFP in the peripheral blood of elderly patients with CHD were significantly increased.And the concentration of sCD40L and YKL-40 was positively correlated with hy-pertension,which can be used to assess the stability and prognosis of CHD.

Venezuelan equine encephalitis (VEE) is a zoonotic disease caused by the Venezuelan equine encephalitis virus (VEEV) complex. This disease has not yet been reported in China, and it is therefore essential to establish a rapid and accurate method for detection of the virus in order to prevent and control this disease. In this study, a one-step real-time quantitative RT-PCR method was developed for the detection of the VEEV complex. A pair of specific primers and a Taqman probe were designed corresponding to a conserved region of the VEEV gene nspl, allowing the detection of all known strains of different sub- types of the virus. Using RNA synthesized by in vitro transcription as template, the sensitivity of this method was measured at 3.27 x 10(2) copies/microL. No signal was generated in response to RNA from Chikungunya virus (CHIKV), nor to RNA encoding the nsp1 fragment of Eastern equine encephalitis virus (EE-EV) or Western equine encephalitis virus (WEEV), all of which belong to the same genus as VEEV. This indicates that the method has excellent specificity. These results show that this one-step real-time quantitative RT-PCR method may provide an effective tool for the detection of VEEV in China.
