Objective To study the morphological characteristics of tumor microvasculature in primary hepatic cell carcinoma (HCC). Methods From Jan. 1998 to Feb. 2002, 32 cases, consisting of 26 male and 6 female, with age ranging from 28 to 76 years [mean (50.56?10.52) years], underwent preoperative digital subtraction angiography (DSA) without theraputic embolization in General Hospital of PLA and 307 hospital of PLA. The diameters of the tumors measured 2～23 (8.05?6.17) cm. The tumor microvessel density (MVD), type and diameter of the tumor microvessels, width of tumor trabeculae, and the size of the malignancy were measured and statistically analyzed. The outcome of the each patient was also statistically analysed. Results The size of tumor tended to be positivly correlated with the pattern of microvasculature of the tumor. The size of the tumor was negatively correlated with MVD, white the tumor size and the diameter of tumor related vessels were positively correlated with the diarneter of tumor trabeculae. Hoverer, the size of the tumor was not correlated with the diameter of vascular trabeculae. Conclusions The density, configuration and the distribution of tumor microvessels were not even in HCC. The features of tumor microvasculature were distinctive at different phases of tumor growth, having definite rules in the development.

Objective To investigate the features of non-senile colonic diverticula as diagnosed by coloscopic examination in 47 cases. Methods 47 cases of non-senile colonic diverticula were diagnosed by colonoscopy in the Department of Endoscopy, General Hospital of PLA, from Jan. 1996 to Dec. 2001. Results There were 38 males and 9 females, whose age was under 60, with a mean age of 43.2 years. The incidence and detectable rate for simple and multiple diverticula showed no relationship to patients' age. The detectable rate of colon diverticula was higher in males than in females. Right colon was the predilection site for both simple and multiple colonic diverticula, especially for simple diverticula. The ratio of incidence for right to left colon was 20.5∶1. The ratio was 2.8∶1 in senile patients (aged above 60, detectable rate of colon diverticula was16.9‰). Conclusion The incidence of colonic diverticula in non-senile patients showed no relationship to age. The incidence of diverticulum in right colon was higher in non-senile patients than in seniors. The incidence of diverticulum in the left colon or both sides of colon was lower in non-senile patients was in seniors.

In order to improve the clinical outcomes and promote the development of enhanced recovery after surgery(ERAS),a full-time specialized role of nurse navigator(NN) was established in Department of Surgery in February,2016. Clinical pathway for ERAS was designed,and role functions,core competencies and responsibilities of NN were formulated. According to the functions and the working frame,NN connected and coordinated teamwork activities,monitored the implementation of ERAS during the overall process. After implementation,the NN had dealt with 10 unusual incidents,the execution efficiency of the 14(82.4%) measurements were 100%,1 measurement was 97%,2 measurements were 94.1%,and 33 patients and 42 medical staff thought highly of the NN. This practice effectively promoted the development of ERAS team and specialist nurse role in our hospital.

Objective To discuss the application of spiral computed tomography and reconstruction technology for patients of depressed nasal bone. Methods The patients of transsection location were backlying on the scan bed and continuously scanning in spiral, and baseline was acou-infraorbital line. The reconstructed image with 2mm layer thickness and 1.5mm overlap can be selected SSD liminal value as bone -wide and surface threshold. Results SSD image can be clearly demonstrated than general nasal bone cross-section profile in the shape, location, size and suitability of filled composite. Conclusion The surface shadow display can be shown nasal bone structure realistically, the three-dimensional anatomic structure images of vessels and the effect of bionics. The bone of volume, distance and angle can be measured exactly by clinical physician, and made the best treatment plan based on the images.

Objective To discuss the relationship between morphological characteristics of tumor microvasculature and blood supply type of primary hepatic cell carcinoma (HCC) through DSA. Methods From Jan. 1998 to Feb.2002, 32 cases, male 26,female 6,aged 28-76 (mean 50.56?10.52) years, underwent preoperative digital subtraction angiography (DSA) without therapeutic embolization in the 301 hospital and 307 hospital. The intervals between DSA and curative resections were 13-70 (mean 31.89?19.11) days. The diameters of the tumors were 2-23 (8.05?6.17) cm. The blood supply type of tumor, the tumor microvasculature density(MVD), type and diameter of the tumor microvessels, width of tumor trabecular were recorded for these cases. The outcomes were then statistically analysized. Results ① Blood supply of the tumor observed on DSA tended to be positively correlated with type of the tumor microvasculature. ②MVD of hypovascular tumors were lower than those in moderate and hypervascular tumors.③The ratio of diameters between tumor microvessel to the trabeculae of the tumor went higher with the increase of HCC blood supply on DSA. Conclusions ①The density, the configuration and the distribution of tumor microvasculature were not evenly distributed in HCC. ②The features of tumor microvasculature possessed distinctive characteristics in different stages of tumor growth, simultaneously with some definite developing rules. ③ Distinct differences in morphological characteristics of tumor microvasculature between different blood supply types of HCC.
