Objective To evaluation the clinical implemented and primary experience of TME combined the double-stapling technique in low rectal carcinoma anus-preserving resection. Methods 22 cases of low rectal carcinoma (the distance between the inferior verge of rectal turnout and the anal verge were 4～7cm) were operated by TME combined the double-stapling technique. Results All of the 22 cases of TME combined double-stapling procedure were successful without operative mortality. Correlative complications including anastomotic leakage (3 cases), anastomotic stenosis (1 case). Temporary completely defunctioning loop colostomy 4 cases. Conclusions TME combined the double-stapling technique in low rectal carcinoma anus-preserving resection is feasibility and the tumour pathology and clinical stage should be considered. Mastering expert operation skill and adherence to sound surgical priciples is the key to prevent and to decrease postoperative complication.

The ancient discussion and modern clinical application regarding Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) in acupuncture verses are explored. Acupuncture verses are the summary of clinical experiences of acupuncture scholars in the past dynasties, of which the records on application of Yingxiang (LI 20) and Neiyingxiang (EX-HN 9) mainly focused on nasal, facial and head-eye diseases, which is characterized with overall summarization, brilliant exposition, simple language, and distinctive characteristics. Nowadays, based on the ancient usage, the clinical application about these two acupoints is continuously developing. If the ancient acupuncture verses could be understood thoroughly, the clinical practice could be better guided and its effects could be improved.

Objective To explore the optimal dose-effect relationship of gene transfer according to the expression of pEGFP in tumor cells under different parameters mediated by microbubble contrast agent and ultrasound in vivo.Methods C57BL/6J mice were inoculated subcutaneously in the middle of the right flank with hepal-6 tumor cells.The mixture of SonoVue and enhanced green fluorescent protein(EGFP)plasmid was injected into the tail vein of each mouse, groups were randomly established according to different output intensity( 1 W/cm2, 2 W/cm2, 3 W/cm2 ), exposure time ( 1 min, 5 min, 10 min) and volume of SonoVue(30 μl,60 μl,90 μl), the expression of EGFP in tumor cells under different parameter was examined by flow cytometry and fluorescence microscopy.Results The expression of pEGFP in tumor cells was significantly higher with the increase of exposure time,output intensity and volume of SonoVue (1 min vs 5 min, P＜0.05; 1 W/cm2 vs 2 W/cm2, P＜0.05 ; 30/μl vs 60 μl, P＜0.05).However, the transfection efficiency of EGFP can not be enhanced continuously with the increasing exposure time,output intensity and volume of SonoVue (5 min vs 10 min, P＞0.05; 2 W/cm2 vs 3 W/cm2, P＞0.05; 60 μl vs 90 μl, P＞0.05).The highest transfection effieieney was achieved under intensities was 2 W/cm2 [(21.02±1.45)%]with 5 min[(23.22±1.91)%] exposed to ultrasound, and 60 /μl SonoVue [ (21.02±1.45) % ].Conclusions Gene transfeetion efficiency changded with the difference parameters.2 W/cm2,5 min and 60 μl SonoVue led to the optimum dose-effect relationship of gene transfer in vivo .

Objective To comprehend the influences of vitamin C ,KCL and dicynone on blood cross matching of saline and mi-crocolumn gel and to compare them with polybrene crossing matching .Methods Under the conditions with and without the specific antibody ,KCI injection ,dicynone injection ,vitamin C injection and normal saline were added for conducting the immunological reac-tion with corresponding RBC .The influences of 3 kinds of drug on different medium cross matching methods of different mediums . Results The low concentration of vitamin C and KCL does not affect polybrene cross matching ,dicynone makes the experiment to generate pseudoagglutination ;the high concentration of these 3 kinds of drug can cause the test to fail .The sensitivity of the saline medium method is slightly lower ,the influence of vitamin C and KCL on the test is inapparent ,while in the KCL method ,with the dilution of antibody ,the agglutination intensity is weakened and even disappeared .Conclusion 3 kinds of drug all have influences on the mierocolumn gel cross matching method ,especially KCL .

Objective To evaluate the relationship between femoral artery intima-media thickness (FA-IMT), stiffness, hemodynamics factors of femoral artery and peripheral vascular disease (PVD) in type 2 diabetes mellitus. Methods According to the presence of PVD, 151 patients with type 2 diabetes were divided into PVD group and non-PVD group. FA-IMT was tested with 2D ultrasound. Ds, Dd, PSV, EDV were observed with color flow rate and volume quantitative technology. FA-IMT, FA-stiffness β, peak systolic velocity (PSV) and end diastolic velocity (EDV) were compared between the two groups. Results Compared with non-PVD group, FA-IMT and FA-stiffness β increased in PVD group (P＜0.01), whereas PSV and EDV decreased in PVD group (P＜0.01). There was no relationship between FA-stiffness β and FA-IMT in PVD group (P=0.01). Multiple Logistic regression indicated the presence of PVD symptoms associated closely with FA-stiffness β, PSV, EDV and duration of diabetes. Conclusion Stiffness β plays an important role in the clinical evaluation of type 2 diabetes mellitus.

Objective To discuss the blood perfusion characteristic of benign and malignant gallbladder disease by contrast-enhanced ultrasound(CEUS).Methods The enhancement characteristic of 62 patients with occupying lesions in gallbladder were observed.Four case of cholecystolithiasis accompany biliary sludge were proven by surgery and remaining 58 case were confirmed by histopathological examination.Their enhancement time and enhancement pattern were analyzed.Results The Time-to peak of benign and malignant disease were (22.4± 4.0)s and (27.7± 2.6)s (t =5.756,P ＜0.01),the Time-to-hypoenhancement of benign and malignant disease were (58.0 ± 7.3)s and (41.5 ± 4.0)s (t =10.33,P ＜0.01),respectively.The peak intensity of benign and malignant disease were (19.2 ± 3.6)dB and (25.1 ± 2.9) dB (t =6.85,P ＜0.01),the mean transit time of benign and malignant disease were (22.72 ± 4.7)s and (6.3± 6.4)s (t =15.001,P ＜0.01),respectively.The destruction of the gallbladder wall of benign and malignant disease were 0％ (0/36) and 57.7％ (15/26) (x2 =25.05,P ＜ 0.01),the inhomogeneous enhancement of benign except biliary sludge and malignant disease were 43.8％ (14/32) and 57.7％ (15/26) (x2 =1.115,P =0.291,respectively).In early phase,78.1％ (25/32) and 80.8 ％ (21/26) of benign disease except biliary sludge and malignant showed hyperenhancement respectively(x2 =3.15,P =0.207).In later phase,84.4％ (27/32) and 76.9％ (20/26) of benign disease except biliary sludge and malignant showed hypoenhancement respectively(x2 =3.615,P =0.164).Conclusions CEUS can obtain the information of blood perfusion and make quantitatively analysis about the enhancement time.It also facilitate the diagnosis of solid occupying lesion in gallbladder.
