Uveitis is a group of inflammatory diseases causing serious impairment of visual function. The precise etiology and pathogenesis remain unclear. lt can be induced by infection, trauma, tumor or autoimmune response, of which autoimmune response is the most common. ln recent years, the cytokines in the process of inflammatory autoimmune diseases role has become one of research hot spots, its role in the pathogenesis and the relationship between the disease activity more and more attention. This article reviews the effects of interleukin, tumor necrosis factor, interferon and transforming growth factor-β in the pathogenesis of uveitis.

ObjectiveTo explore the possible pathogeny of tension headache(TH) as well as some emotional and cognitive function impediment.Methods53 cases with tension headache were given coronal CT or MRI examination and cervix X-ray examination.Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS) and Mini-Mental State Examination(MMSE) were used to assess their emotion and cognition.ResultsThere were 14 cases of magnitude mental events induced anxiety and/or depression,23 cases of work tensions induced anxiety,14 cases of work tensions induced depression,and 12 cases of lightly cognitive impediment.ConclusionTension headache patients usually related with continued convulsion of cervical muscle induced by hard work and life.Most of them represent more or less emotional impediment,part of them represent lightly cognitive impediment.

Purpose:To explore the preventive effect of hepatic arterial infusion (DDS) against recurrence of hepato- cellular carcinoma (HCC) after radical resection.Methods:From Jan,1996 to May,1998,287 patients of HCC after radical resection were randomly divided into four groups:intra-hepatic arterial infusion(97),intra-portal vein(80),intra-hepatic artery and portal vein (60),control (50).All patients received chemotherapy for two years and observed for postoperative recurrence of HCC.Results:The postoperative recurrence rate of HCC with intra-hepatic arterial infusion was significantly lower than that of intra-portal vein (P0.05).The 1～、2～ and 3～year survival rate of intra-hepatic arterial infusion was significantly higher than any of the other groups.Conclusions:Intra-hepatic arterial infusion (DDS) through gastro-duodenal artery can effectively pro- long the postoperative survival and decrease the post-operative recurrence rate of HCC.The preventive method of DDS through gastro-duodenal artery was safer and effective.

Objective: Study on the growth character of B16 melanoma cell which can express angiostatin. Methods: Angiostatin gene was constructed from human plasminogen cDNA by deletion mutation. A B16 melanoma cell clone named BAG28 which stably expresses angiostatin was established by introducing gene into it. Results: BAG28 in vitro had no changes in proliferation rate and the ability of clone formation in soft agar. Study in vitro showed that the tumor weight had reduced about 87% ( P

OBJECTIVE To comprehend the main pathogens and their drug resistance of multiple organ dysfunction syndrome(MODS) patients in ICU.METHODS We retrospectively analyzed all the bacteria isolated from 40 MODS patients in ICU.RESULTS The number of bacteria strains isolated was 173,92 G-bacteria strains made up 53.18%,60 G+ bacteria strains made up 34.68%,and 21 fungi strains made up 12.14%.The top six were Staphylococcus aureus(23.70%,MRSA was 13.87%),Pseudomonas aeruginosa(14.45%),Acinetobacter baumannii(11.56%),Stenotrophomonas maltophilia(8.67%),Candida tropicalis(8.09%),and Enterococcus faecalis(7.51%).The susceptive rate of S.aureus and Enterococcus to vancomycin was all 100%,the susceptive rate of A.baumannii and Klebsiella pneumoniae to carbapenems was high.64% patients had the multiplicity of infection(MOI) which always linked with long period in ICU,respiratory failure and mechanical ventilation.CONCLUSIONS MODS patients have a high morbility of G+ bacteria,fungi and MOI,most pathogens show multi-resistance to commonly used antibiotics.Strengthening the monitoring of infection and reasonable using antibiotics should be taken.

Objective:To provide imaging evidence for the treatment of anterior disc displacement without reduction by the injection of sodium hyaluronate into temporomandibular joint (TMJ).Methods:40 patients with anterior disc displacement without reduction were injected 3 times with sodium hyaluronate into the TMJ.Patient's TMJ and clinical symptoms were examined 3,9 and 12 months after treatment.The clinical parameters of Fricton's Craniomandibular Index(Fricton index),maximal mouth opening(MMO),pain intensity of a visual analog scale(VAS) and CBCT radiographic data of 48 TMJs from 40 patients were analysed.Results:The CBCT images showed that at 9 and 12 months follow-up the surface of the condylus became smooth,the density of the cortical bone and the adjacent subcortical bone increased and osteophyte in condylar head decreased(P =0.026,P =0.001).As for disc displacement without osteoarthritts,9 months after treatment condylus were moved forward(P =0.038).VAS and Fricton index were reduced(P ＜0.05),MMO was increased (P ＜ 0.05).3-12 months after treatment,there was no statistical difference of Fricton index (P ＞ 0.05).Conclusion:Injection of sodium hyaluronate into TMJ can remodel the condylar bone surface but cant make condyle back to the middle of acetabulum.

This study investigated the effect of etoposide, an anticancer chemotherapy drug, on B7-H1 expression in retinoblastoma (Rb) cells and the role of miR-513a-5p in the process. Rb cells were divided into control and etoposide groups. In the etoposide group, cells were treated with etoposide at different concentrations (2.5, 5, 10, 20 and 40 μg/mL) for 24 h. Those given no treatment of etopside served as controls. Reverse transcription polymerase chain reaction (RT-PCR), fluorescence quantitative PCR and flow cytometry were performed to measure the mRNA and protein expression of B7-H1 in Rb cells. The mRNA expression of miR-513a-5p in Rb cells before and after etoposide treatment was also detected by fluorescence quantitative PCR. The miR-513a-5p mimics and the miR-513a-5p inhibitor were transfected into Rb cells separately, and fluorescence quantitative PCR and flow cytometry were used to detect the effect of the miR-513a-5p mimics or inhibitor on B7-H1 expression. TargetScan5.2 was employed to predict the miR-513a-5p binding sites in the 3'-untranslated region of B7-H1 mRNA. Luciferase reporter plasmids carrying this site were prepared and transfected into Rb cells and luciferase activity analyzed. The results showed that etoposide stimulated the mRNA and protein expression of B7-H1 in Rb cells, which reached a maximal level after treatment with 5 μg/mL etoposide (P<0.05). However, miR-513a-5p expression was decreased in Rb cells after etoposide treatment. When the miR-513a-5p inhibitor was added, B7-H1 expression was increased with the concentration of the miR-513a-5p inhibitor (P<0.05). Moreover, B7-H1 expression was decreased gradually with the concentration of the miR-513a-5p mimics increased (P<0.01). Additionally, the miR-513a-5p mimics were found to inhibit the luciferase activity. It was concluded that etoposide can promote B7-H1 expression in Rb cells, which may be associated with chemoresistance. The promoting effect of etoposide on B7-H1 expression can be reversed by miR-513a-5p mimics. MiR-513a-5p inhibits the mRNA and protein expression of B7-H1 via binding to the 3'-UTR of B7-H1 mRNA.

ObjectiveTo study the effects of early rehabilitation on symptom, range of motion (ROM) and motor function of upper extremity of patients with shoulder-hand syndrome after stroke.Methods47 patients were divided into two groups,early rehabilitation group and non-early rehabilitation group.Two groups were treated with comprehensive rehabilitation. The passive ROM, the pain and motor function of affected limb was assessed by Fugl-Meyer Assessment.The evalution was done in pre-treatment and post-treatment respectively. Results1.The passive ROM decreased and the pain of affected limb of the early rehabilitation group were less than the non-early rehabilitation gronp when the shoulder-hand syndrome occour.2.After comprehensive rehabilitation treatment,their clinical symptom ROM and motor function of upper extremity impoved significantly in patients with shoulder-hand syndrome after stroke( P<0.05).The early rehabilitation treatment has better effects. Conclusions The early rehabilitation treatment could decrease the degree of their passive ROM decrease and the pain of affected limb in patients with shoulder-hand syndrome after stroke,and the patients who accepted earlyrehabilitation seemed easly to improve by comprehensive treatment.
