The concept of white matter dementia was first introduced by Filley in 1988.It was found following behavioral neurologica researches that patients with this type of dementia manifested the dysfunctions of sustained attention,memory retrievial,frontal lobe and visualspatial function.They also had psychiatric manifestations but language and extrapyramidal function remained normal.10 diseases of white matter disorders are listed for understanding the clinical characteristics of this type of dementia.

Objective To study the clinical value of serum SCC,CYFRA21-1,NSE and CEA for patients with nasopharyngeal carcinoma (NPC) and squamous cell carcinoma of head and neck (NHSCC). Methods From Aug 2004 to Sep 2007, the serum levels of SCC, CYFRA21-1, NSE and CEA were detected in 79 NPC and 51 HNSCC before and after radiotherapy. The clinical related factors were analyzed. Results Before treatment, the positive rates of serum SCC, CYFRA21-1, NSE and CEA for patients with NPC were 10.53 %, 46.75 %, 17.5 % and 2.04 %, respectively. The sensitivity of combined detection was 78.95 %. The positive rates for patients with HNSCC were 22 %, 19.75 %, 11.11% and 0, respectively. The sensitivity of combined detection was 36.17 %. The level of SCC was related to staging in HNSCC group. CYFRA21-1 was related to the rote of treatment response in NPC group. Conclusion The sensitivity of combined detection of tumor markers were significantly increased. CYFRA21-1 associated with NPC and SCC with HNSCC were noted in this study.

Objective To discuss the responsibility and quality requirement of head nurses in nursing quality improvement in obstetrical and gynecological department.Methods The responsibility of head nurses in nursing quality improvement in obstetrical and gynecological department were investigated by carrying out surveys in patients of obstetrical and gynecological department.Results The quality of head nurses needed improvement and their responsibility required definitude,thus the satisfaction degree of patients and nursing quality can be improved.Conclusions Through this research,we find that the head nurses not only need good quality,but also should be given definite responsibility and certain service,supervising and management power,if so,they can fully exert their role in nursing work.

Acute pancreatitis can lead to dysfunction of gut mucosa barrier, translocation of intestinal bacteria, damage of immune function. Immune nutrition substances such as glutamine, arginine, -3 polyun-saturated fatty acids (-3 PUFAs),dietary fiber (DF) can prevent dysfunction of gut mucosa barrier and translocation of intestinal bacteria, enhance the immune function, promote the recovery of acute pancreatitis. The article reviewed domestic and. overseas documents to on the contribution of immune function to acute pancreatitis.

Objective To investigate the expression of vascular endothelial growth factor (VEGF)、matrix metalloproteinase-2(MMP-2) and matrix metalloproteinase-9 (MMP-9) in tongue squamous cell carcinoma and the clinical significance.Methods The expression of MMP-2,MMP-9 and VEGF in 60 cases of tongues quamous cell carcinoma tissues and in 20 cases of normal tongues tissues were examined by immunochemistry.Results The expression of MMP-2,MMP-9 and VEGF was higher in tongues quamous cell carcinoma than that in normal pancreatic parenchyma.In cases with lymph nodes metastasis and TNM stage Ⅲ + Ⅳ,the expression of two markers were significantly higher than those without lymph nodes metastasis and TNM stage Ⅰ + Ⅱ (P ＜ 0.05).A positive correlation was found between the expression of VEGF and MMP-2,MMP-9 in tongues quamous cell carcinoma ( P ＜ 0.05 ).Conclusion The expression of MMP-2,MMP-9 and VEGF was closely correlated with lymph nodes metastasis and TNM stage of tongues quamous cell carcinoma(P ＜ 0.05 ).VEGF and MMP-2,MMP-9 play an important role in the development of tongues quamous cell carcinoma,may cooperate with each other.

Objective To discuss the surgery for the patients with bruise of bilateral frontal lobes complicated with central encephalocele.Methods 48 patients diagnosed as bruise of bilateral frontal lobes complicated with central encephalocele were analyzed retrospectively.According to the results of CT and clinical symptoms,timing of surgery was selected.All patients were given unilateral decompressive craniectomy or bilateral decompressive craniectomy.Results All patients were followed up for 1 year.42 cases survived,while 6 cases died.All cases were estimated with GCS:18 cases ( 37.5％ ) were cured excellently,16 cases ( 33.3％ ) were mild morbidity,5 cases ( 10.4％ ) were severe morbidity,3 cases ( 6.3％ ) were in persistent vegetative state and 6 cases ( 12.5％ ) were dead.Conclusion The progression of patients with bruise of bilateral frontal lobes comphcated with central encephalocele were rapid.Diagnosis and treatment at the early stage could improve patients' prognosis.

Positron emission tomography (PET)/CT plays an important role in the diagnosis of bone metastasis from lung cancer,and can reflect the pathophysiological and morphological changes in lesion of bone metastasis.The sensitivity,specificity and the overall accuracy of PET-CT for the diagnosis of bone metastasis in patients with lung cancer are higher than those of routine methods such as X-ray,CT scan,MRI and SPECT/CT.

ObjectiveTo study the clinical effect of sodium aescinate on the edema of limb tibial plate fracture.Methods69 patients with edema of limb of tibial plate fracture were randomly divided into two groups,treatment group(46 cases)and control group(23 cases).Both of them were transfused with 20％ mannitol(250ml,Bid ×7days).In addition,these patients in the treatment group were treated with sodium aescinate(30mg Qd × 7days).ResultsThe repercussive effect of the edema grade in the treatment group were obviously better than those in the control group(P ＜0.05 ).ConclusionSodium aescinate had a remarkable repercussive effect on the limb edema of tibial plate fracture.

The diagnosis and treatment of age-related macular degeneration (AMD) is an international hotspot of eye research.Successful clinical applications of anti-VEGF drugs promoted both basic research and clinical practice of AMD.A number of countries and professional societies have established clinical guidelines for AMD management,including the epidemiology,risk factors,diagnosis,classification,and treatment process.These AMD guidelines are mostly based on recently published results of clinical trials,provided good model of evidence based medicine.It is urgent and necessary to have our own guideline which is suitable for Chinese patients.Reviewing and learning existed guidelines will help us to improve the clinical practice of AMD in China.

Objective To explore the expression of cyclooxygenase-2(COX-2) in non-small cell lung cancer (NSCLC) and its relationship with NSCLC development. Methods Expression of COX-2 protein was detected in 45 eases of NSCLC tissues and 45 cases of paracaneerous tissues by immunohistochemistry assay. Results Expression of COX-2 was detected in a significantly greater proportion of NSCLC tissues(64.4 % ) than that of paracancerous tissues(31.1% )(P＜0.05 );expression of COX-2 in different gender, age and tissue differentiation was no significant difference(P＞0.05);expression of COX-2 in adenocarcinoma was obviously higher than that in squamous carcinoma(P＜0.05);expression of COX-2 in the diameter of carcinoma tissue above 3cm was significantly higher than that below 3cm(P＜0.05) ;expression of COX-2 in carcinoma tissue existing lymphnode metastasis was obviously higher than that in non-existing lymphnode metastasis( P＜0.05 );expression of COX-2 in stage Ⅲ+Ⅳ of TNM was significantly higher than stage Ⅰ + Ⅱ of TNM(P＜0.05 ). Conclusion COX-2 was involved in occurrance and development process of lung cancer.
