ABSTRACT
Objective To investigate the clinical efficacy of rectal resection for rectal cancer.Methods 35 patients with rectal cancer were diagnosed by pathological examination.They were treated with laparoscopic rectal cancer resection and conventional chemotherapy.The patients were followed up for 3 years.The operative time,blood loss,intraoperative and postoperative complications,postoperative recovery,death and so on were observed.Results The patients were operated successfully,and no tumor cells were found in the bowel edge.The average operative time was (171.74 ± 58.24) min,average blood loss was (85.74 ± 68.32) ml,there were no infection,bleeding,anastomotic complications.After 2 ～ 3 years of follow-up,there was 1 patient with liver metastases,and no local recurrence,no fecal incontinence and no deaths.Conclusion Rectal resection for rectal cancer had good effect and could improve patients' quality of life.
ABSTRACT
Objective To observe the effect of computer anorectal therapeutic apparatus in treatmenf of hemorrhoids. Methods 100 cases of hemorrhoids were selected and randomly divided into A group and B group,each group 50 cases. The patients of A group were treated by computer anorectal therapeutic equipment. The patients of B group were administrated with traditional surgical treatment. Then the pain, urine retention, wound edema, the occurrence of postoperative bleeding, wound healing time and the average following - up outcome were observed within 3 days after operation. Results A group had occur pain, urine retention, wound bleeding and wound edema in cases of 3,1,1,8 respectively, and B group had them in cases of 7,3,5,13 respectively,there was no significant difference between the two groups(all P ＜0. 05). The healing time of A group and B group was (13. 5 ±4.6) days and (14.3 ± 4.9) days respectively, there was no significant difference between the two groups (P ＞ 0. 05). 46 cases of A group were cured , 42 cases of B group were cured, there was no significant difference between the two groups (P ＞ 0.05). Conclusion Computer anorectal therapeutic apparatus in treatmenf of hemorrhoids could reduce hemorrhoids bleeding, pain, urine retention ,edema and wound complications, and had good effect.
ABSTRACT
uring last 16 years we have successfully developed the computer-assisted vectorcardiogram analysis systems: model TJ-Ⅰ, TJ-Ⅱ, and TJ-Ⅲ, but some technical problems remained unresolved, such as the recognition accuracy for vectorcardiograms, measurement of the parameters of complicated QRS waves, the ratio of T loop length to width, and the area of spatial vectors etc. A new system, model TJ-Ⅳ was designed to resolve these technical problems. The system was equipped with a 586 computer with a CPU of 120 MHz. Special new low-noise amplifier was employed and C language was used for programming. Three graph recognition techniques were used to enhance the accuracy of VCG recognition. 32 orthogonal electrocardiograms and vectorcardiograms were displayed and printed, and 566 parameters of vectorcardiograms were calculated. Our results with 150 cases showed that the system had high accuracy of graph recognition, and parameter calculation and the results were essentially consistent with those of manipulative methods. We were led to concluded when compared with TJ-Ⅲ system, the new version has higher accuracy of processing and measurement for vectorcardiograms, is able to process more vectorcardiographic parameters, with higher processing speed.

ABSTRACT
Objective To study the effects of angiogenesis inhibitor SU5416 on the growth and metastasis of pancreatic cancer in SD rat model. Methods Dimethylbenzanthracine (9 mg) (DMBA),was implanted into the parenchyma of Sprague Dawley rat pancreas to induce pancreatic cancer. Rats with established pancreatic carcinoma were randomly divided into 4 groups (15 rats each) to receive every the other day for consecutive 13 weeks before sacrifice peritoneal cavity injection of: Normal saline (control),5-fluorouracil 30 mg?kg -1 (5-Fu group),SU5416 16 mg?kg -1 (SU5416 group),and both 5-Fu and SU5416(combined treatment group). Tumor weight,inhibition rates,intratumoral microvessel density (MVD),apoptotic index (AI) and metastasis were evaluated. Results Tumor weight was (1.15?0.21) g,(0.68?0.42) g,(0.31?0.11) g,(0.19?0.06) g respectively;the inhibition rate was 0,48%,80%,85% respectively;the intratumoral microvessel density (MVD) was (12.3?3.2),(11.4?3.8),(2.1?1.5),(1.8?1.1) respectively;The apoptotic index (AI) was (2.64?1.86)%,(5.71?3.14)%,(13.21?4.26)%,(21.12?7.15)% respectively. Peritoneal metastasis was significantly less severe in 5-Fu group,SU5416 group and combined group than that in control group(83% versus 46%,25% and 0) ( P
