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 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.

Functional delayed gastric emptying,also calls gastric paralysis,often occurs after abdominal operation,which severely affect patients prognosis.The mechanism,clinical manifestation,diagnosis,preservation and treatment are summarized in this review.

BACKGROUND:At present,there are differences in reporting culture condition of cochleal spiral ganglion cells(SGCs)in circle of primary cell culture.Individual method has poor repeatability,and is not beneficial for practical application.OBJECTIVE:To primary culture and evaluate SGCs of neonatal C57 mice.METHODS:Tissues from cochlear modiolus were acquired from neonatal C57 mice by microanatomy.SGCs from cochlear modiolus were cultured by trypsin digestion,differential velocity adherent technique combined with chemicals.Cell growth was observed by inverted phase contrast microscope and hematoxylin and eosin staining.Immunocytochemistry was employed to classify cell types.RESULTS AND CONCLUSION:After purification,the call body of SGCs from cochlear modiolus was ellipse or triangle,with slender processes in cytoplasm.Nuclei were positive for Nuen(stained brown).Cytoplasm and axon were positive for β3-Tubulin stained brown).These indicated that mouse SGCs were successfully cultured.

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 explore the pathological and imaging features of adenosquamous carcinoma (ASC) of pancreas.Methods Both clinical data and imaging findings in seven cases with pathologically proved ASC of pancreas were analyzed retrospectively.Imaging features were compared with pathological results.Results 1 )The disease mainly occurred in people around 55 years, among the 7 cases ,5 located in the pancreatic head, 2 in the body and tail, with abdominal pain and jaundice as the chief complaint.2)Pathologically, the solid part of the tumor was made up of ductal adenocarcinoma and squamous carcinoma components, with a different rate, while the cystic part was made up of necrosis, liquefaction.3) the imaging of 5 cases with ASC of pancreas in which squamous carcinoma components predominate shows solid and cystic tumors of pancreas, furthermore the ratio of central cystic diameter and the whole tumor diameter increase with the the volum of the tumor.4) There is no partitioning in the cystic part of the tumor, with a few irregular microcyst around it.5 ) The tumor shows a pattern of infiltrative growth, associated dilatation of the common bileduct or pancreatic duct in all cases, pancreatic atrophy in part.6) Squamous carcinoma components of the tumor was the pathologic basis for the formation of the solid and cystic structure in imaging.Conclusions ASC of pancreas is a rare aggressive subtype of pancreatic adenocarcinoma with a worse prognosis than the usual type of ductal adenocarcinoma, although symptoms similar to pancreatic ductal carcinoma.Cases of ASC of pancreas in which squamous carcinoma components predominate have certain characteristic imaging and pathologic features,which is important to early diagnosis.

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.

Objective To observe the neuroprotective effect of Copolymer 1 ( Cop 1) in rats with elevated intraocular pressure (IOP), and explore the clinical application of Cop 1 in the prevention of optic nerve atrophy induced by glaucoma. Methods Thirty adult Wistar rats were rendered for elevation of IOP in both eyes by Shareef-Sharma method. At the third week of IOP elevation, a mixture (1:1) of Cop 1 (100 μg) emulsified in complete Freund's adjuvant (CFA) was injected intracutaneously at two hind footpads in 15 rats (Cop 1 model group), and the other 15 rats were given the same dose of PBS emulsified in CFA (model control group) . Retinal ganglial cell (RGC) retrograde labeling was performed with Fluorogold 6 d later, and retina was taken after 24 h to compared the density of RGC between two groups. Another normal rats were served as blank controls. Results It was found that lymphocytes were accumulated on the histological slices of retina and optic nerve in Cop 1 model group. The rates of RGC loss of Cop 1 model group and model control group were 10. 24% ± 3.75% and 29.00% ±6.92%, respectively. The RGC density in Cop 1 model group was significantly lower than that in model control group (P <0. 05), while there was no significant difference in that between Cop 1 model group and blank control group (P >0.05). Conclusion Intracutaneous injection of Cop 1 can reduce the damage of RGC induced by elevated IOP.

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.

AIM: To investigate the efficacy and safety of liduofen in the treatment of patients with osteoarthritis of the knee joint. METHODS: A randomized, double-blind, parallel-controlled, multi-centre study was adapted to compare the efficacy and safety between liduofen and Olfen-75 in 136 patients. Patients were randomly assigned into two groups: liduofen group which was received 75 mg (diclofenac) Liduofen injection (n=69) once a day for seven days and Olfen group which was received 75 mg (diclofenac) Olfen-75 injection (n=67) once a day for seven days. RESULTS: After the treatment, similar improvements for rest pain, pain on exercise, swelling of joint, pressing pain of joint, knee joint bend extend function measured using a 10 cm visual analogue scale was performed in two groups. In Olfen-75 group, the rate of efficacy was 62.69% in the 3rd day, 95.76% in the 5th day and 97.88% in the 7th day. While in liduofen group, the rate of efficacy was 57.97% in the 3rd day, 93.87% in the 5th day and 96.94% in the 7th day. In liduofen and Olfen-75 groups, the progressive rates were 56.72% and 55.07%, respectively. The total improvement rates were 89.85% and 92.54% respectively (P＞0.05), and the rates of side effects were 0% and 1.49%, respectively (P＞0.05). CONCLUSION: Liduofen is an effective and safty drug inthe treatment of patients with osteoarthritis of the knee joint. There is no significant difference on efficacy and safety between the two groups using liduofen and Olfen-75.
