Objective To investigate the correlation between the severity of subcortical ischemic lesions and vascular cognitive impairment in encephalorrhagia patients. Methods One hundred and twenty-four encephalorrhagia patients were enrolled into two groups, the normal cognition group (60 cases, without cognitive impairment) and the cognitive impairment group (64 cases, with vascular cognitive impairment). Parameters of the lesion diameters, various lesion locations, white matter lesions severity and NIHSS scale score, modified Bathel index score were compared between these two groups. The correlations between the above indexes and the vascular cognitive impairment degree were analyzed by Logistic regression proceduress. Results Compared to the normal cognition group, the indexes of lesion number of frontal area and basal ganglia, lesion diameters, white-matter severity and NIHSS scale score of cognitive impairment group were higher (P<0.05, respectively), and the modified Bathel index score was lower (P<0.05), but the lesion number in temporal, parieto-occipital and infratentorial area were not changed (P>0.05, respectively) in the cognitive impairment group. Result of Logistic regression analysis showed a positive correlation between the severity of white-matter and the degree of vascular cognitive impairment (OR =4.705, P=0.009). Conclusion The severity of white-matter can effectively assess the degree of vascular cognitive impairment of encephalorrhagia patients.

Objective To compare the efficacy of laparoscopic radical hysterectomy and open surgery with early stage cervical cancer in elderly patients.Methods Performed a retrospective study of 195 cases underwent surgical treatment of early stage cervical cancer in elderly patients.According to different approach,the patients were divided into laparoscopic group (66 cases) and open group (129 cases).The operation time,intraoperative blood loss,number of resected lymph nodes,bowel function recovery time,postoperative hospital stay and postoperative complications was compared between two groups.Results The operation time,intraoperative blood loss,bowel function recovery time,postoperative hospital stay in laparoscopic group were significantly shorter than those in open group [(237.6 ±46.9) min vs.(259.3 ± 76.7) min,(214.7 ± 104.8) ml vs.(283.4 ± 137.2) ml,(1.9 ± 1.2) d vs.(2.8 ± 1.5) d,(4.1 ± 3.5) d vs.(6.7 ± 1.4) d,P ＜ 0.05 or ＜ 0.01].There was no significant difference in number of resected lymph nodes and postoperative complications between laparoscopic group and open group (P ＞ 0.05).Conclusion Laparoscopic radical hysterectomy is both safe and effective in elderly patients with early stage cervical cancer.

Objective: To observe the preventive effect of Bu Shen Jian Pi Capsule on age-related cochlear hair cells apoptosis in C57 BL /6J mice,and research its mechanism of action.Methods: 30 new born C57 BL /6J mice were divided into 2 groups,with 10 animals in control group(CG) and 20 animals in Bu Shen Jian Pi Capsule (experimental group,EG).The animals in CG were fed regularly,while those in EG were fed regularly at the first one months after the birth and then,commonly fed water was substituted by the medical solution of Bu Shen Jian Pi Capsule for these animals in EG.The experimental course lasted for seven months.The cochleas of the two groups of mice were taken out for cochlear surface preparation,then being observed under optical microscope with a comparative analysis on the status of degenerative changes in the hair cells of cochlear between the tow groups.Results: Cochlear hair cells damage of CG animals showed aggravating tendency with the increase of the age,and followed the developmental rules of lesion progression in cochlear hair cells from the basal turn to the apical turn and with the number of outer hair cells loss greater than that of inner hair cells.In contrast,the cochlear damage of animals of EG was relatively milder than that in animals of CG,compared among the animals at the same age between them.Conclusion: This study showed that Bu Shen Jian Pi Capsule could postpone age-related cochlear hair cells apoptosis in C57 BL /6J mice,therefore,it suggested that Bu Shen Jian Pi Capsule might possess the pharmacological action of preventing presbyacusis.We assume the possible protective mechanism of Bu Shen Jian Pi Capsule might be related to increase of cells cAMP,regulation of metabolism of nucleic acid,and protectoin or stabilization of DNA structure.

Objective　To optimize the oral contrast media in three-dimensional display of gastric lesions. Methods　41 cases were randomly divided into 3 groups according to different oral contrast media administered: No. 1 air contrast group (n=17), No. 2 fat emulsion group (n=7) and No. 3 positive contrast group (n=25). The 3D CT images were reconstructed using MPR, SSD, RaySum display and virtual endoscopic techniques, and compared with gastric endoscopy and/or conventional barium study.Results　The detectability of gastric lesions using fat emulsion and air contrast was 42.8%(3/7) and 80.0%(20/25), respectively, both were significantly lower than that using positive contrast (100%, 30/30) (χ2=19.22,P＜0.01;χ2=6.60, P＜0.05). The capability of showing the details of stomach lesions was significantly affected by the oral contrast media administered（χ2=17.04，P＜0.01）. Conclusion　It is very important to choose the appropriate oral contrast media for 3D display of gastric lesions in spiral CT, the positive contrast agent is the optimal choice.

Analysis was made in 3 patients with central nervous system lymphoma(CNSL) with different manifestations;neuroradiological and immunocytological investigations were used to improve the clinical diagnosis of CNSL.Three patients with CNSL presented with 3 distinct profiles:diffuse meningeal invasion, intracranial masses of tumor and intramedullary spinal invasion. Both contrast enhanced CT and MR provided CNSL lesions in the brain parenchyma and meninges. It is suggested that combining CT,MR findings and immunological markers can improve clinical diagnosis of CNSL.
