Cytokines involve in many diseases. It' s reported that reduction or increase of cytokines is an important factor to lead to immunological diseases in nervous system. Other studies have found that certain cytokines in the different stages of the same disease play a different role. Understanding the specific mechanisms of cytokines in autoimmune diseases of the nervous system is necessary for providing theoretical basis of new ways to treat these diseases. This article will review the progress of some main cytokines in nervous systemic immunological diseases.

Objective To introduce the recent studies about the lymph node-targeted chemotherapy for gastric carcinoma. Methods The literatures on the lymph node-targeted chemotherapy for gastric carcinoma in recent years were collected and reviewed. Results The lymph node-targeted chemotherapy for gastric carcinoma was effective because it couled improve the drug concentrations in regional lymph node. Conclusion As a part of multiple treatments for gastric carcinoma, lymph node-targeted chemotherapy will be further developed.

The incidence of carotid stenosis disease increases with age,and it is one of the major causes of ischemic stroke.In recent years,with the rapid development of endovascular treatment technology,the therapeutic means,including carotid angioplasty and stenting,has been widely carried out both at home and abroad.This article reviews the advances in endovascular treatment of carotid stenosis.

Objective To investigate the inhibitory effect of cyclooxygenase-2 (COX-2) inhibitor celecoxib alone and in combination with somatostatin (SST) analog octreotide on human gastric cancer. Methods Fifty one gastric cancer patients were randomly divided into 3 groups. The patients in control group(n=15)took no medicine before gastric cancer resection. Celecoxib group(n=18)patients took celecoxib orally 0.2 g/d for 7 days before surgery. Combination group(n=18) patients took celecoxib orally 0.2 g/d and were injected octreotide 100 ?g/d subcutaneously for 7 days before surgery. The resected specimens were examined histologically, including status of tumor necrosis, inflammatory cells infiltration and fibrous tissue proliferation. The microvessel density (MVD) and the expression of COX-2 in gastric cancer were evaluated by immunohistochemical methods. The apoptosis of tumor cells was measured by terminal deoxynucleotidyl transferse-mediated-dUTP nick end labeling. The expression of somatostatin receptor (SSTR) -1,SSTR-2 and SSTR-3 mRNA in gastric cancer tissue obtained by biopsy in all patients were detected by using real time fluorescence quantitative RT-PCR. Results Compared with control group, gastric cancer tissue necrosis increased significantly(P

Objective To observe the effect and study intervenient action of Kuijieling Granules (KG) in treating ulcerative colitis (UC) during the active period by the clinical experiment. Methods The patients of active UC (damp-heat syndrome) were randomly divided into 2 groups (KG+SASP group and SASP group) to observe pathological changes of the mucosa,syndrome effect and main symptoms scores,and the protein expression of TLR4,CD14 and NF-?B p65 were detected by immunohistochemistry. Results KG+SASP group had better effect than SASP group in syndrome and mucosa (P0.05). There were outstanding differences among the pathologic grade of UC about IA of TLR4,CD14 and NF-?B p65. The expression of TLR4,CD14 and NF-?B p65 were decreased by treatment (P

Objective To establish the animal model of damp-heat syndrome(DHS) and explore the expression of aquaporin(AQP) 3,4 gene in gastric mucosa.Methods Thirty SD rats were randomized into 3 groups and observed for 20 days.Group A(normal group,NG) was fed with routine method.Group B(Pi deficiency syndrome group,PDS) was fed alternatively with routine method and aqua of cassia angustifolia Vahl.Group C(DHS) was fed with fat,honey liquid and treated with damp-heat environment.The expression of AQP 3,4 gene in the 3 groups were determined by fluorescence quantitative polymerase chain reaction(FQ-PCR).Results The symptoms and signs in Group C were simiar to the clinical DHS.Expression of AQP3 gene in DHS was statistically significant higher than that in PDS and NG(P

Objective To compare dual-energy X-ray absorptiometry T-score concordance between hip and lumbar spine, and to estimate the value of T-score of the hip for diagnosing osteoporosis in the elderly. Methods From September 2000 to May 2002, 123 males aged 60-89 years (average 72.0?7.4) and 137 females aged 60-88 years (average 67.3?6.1) were selected in the study based on the exclusion of subjects with apparent abnormalities affecting bone mass or taking medications which might affect bone metabolism. Detailed questionnaire included lifestyle factors such as smoking, drinking, exercise and dietary habits, etc. Radiographs of the thoracic and lumbar spine were taken. Patients' BMD were measured by DEXA (DMS, Challenger) at lumbar spine (L 2-4) and left hip in posterior-anterior projection. The right hip was scanned if patients had a history of fractures or any bone disease in the left hip. All data were statistically analysed using SPSS 8.0 system. Results The average T-scores of bone mineral density of the lumbar spine were higher than that of the hip in all male patients and in 65-, 85- age groups of female patients(P

Objective:To analyze the characteristics and differences of upper airway forms in the adults with class Ⅱ sagittal facial type of different vertical facial types and investigate the correlation between craniofacial structures and upper airway forms.Methods:Cephalograms of 135 adults with classⅡsagittal facial type of different vertical facial types were collected.60 cases were males and 75 cases were females.All the cephalograms were measured in sagittal upper airway depths.The differences were compared between genders,and also among different vertical facial type groups.Results:Among different vertical facial type groups,only the sagittal depths of nasopharynx(PNS-Ba、PNS-R)of the males and PNS-Ba of the females in high angle groups were smaller than that in average and low angle groups(P0.05),but the values of V-LPW of the males were larger than that of the famales in all vertical facial type groups(P
