Objective To investigate the changes of excitatory amino acids of cerebrospinal fluid(CSF) in patients with acute cerebral infarction(ACI) and its clinical significance.Methods The CSF levels of excitatory amino acids including glutamate(Glu) and aspartate(Asp) in 30 cases with ACI and 20 control subjects with migraine were measured by high performance liquid chromatography.Results Glu and Asp levels in patients with ACI were significantly higher than those of the controls(all (P

Objective To detect the expression of serum soluble E?cadherin(sEC)before and after operation in breast cancer patients,and to ex?plore its clinical significance. Methods The levels of sEC in 42 patients with breast cancer and 18 patients with benign breast diseases were tested by enzyme?linked immunosorbent assay(ELISA)before and after operation as well as in 30 healthy controls. Its correlation with clinical and patho?logical characteristics was analyzed. Results The levels of sEC in breast cancer patients before operation were significantly higher than patients with benign breast diseases and controls,which declined significantly after operation. Moreover,the levels of sEC in those with high clinical grading and lymphatic metastasis were also higher than in the ones with low grading and negative lymphatic metastasis(P<0.05). Conclusion The levels of sEC in breast cancer patients before operation are specific and closely related with pathological grade and lymphatic metastasis,which may be a pre?dictive factor for prognosis of breast cancer.

Objective To evaluate the diagnostic value of hysteroscopy in comparison with hysteros- alpingography(HSG) in the detection of intrauterine abnormalities in infertile patients.Methods 52 patients(ob- serving group) with filling defects under HSG received hysteroscopy,and the remaining 22 patients (contrasting group) with normal hysterosalpingographic findings also received hysteroscopy with their consent.Results In- trauterine abnormalities in observing group and contrasting group confirmed by hysteroscopy were 78.8 % and 9.1% respectively,and there was statistical significance(P

Objective To evaluate the effectiveness of discharge planning and home care for patients with peritoneal dialysis (PD).Methods A total of 60 PD patients were randomly divided into the intervention group and control group,30 cases in each group.Discharge planning and home care were carried out in the intervention group, while routine nursing and telephone follow -up service after discharge were implemented in the control group.The patientsˊscores of Zung Self -Rating Anxiety Scale(SAS),Self -Rating Depression Scale(SDS),Self management ability of patients undergoing peritoneal dialysis,complication rate and readmission rate were compared between the two groups at the next day admission,discharge,lth month and 3th after discharge.Results The scores of SAS and SDS in the intervention group were significantly lower than that in the control group at 3th month after discharge,the difference was statistically significant(tSDS =5.263,tSAS =3.812,P <0.05).The Self management ability of patients undergoing peritoneal dialysis was significantly higher than that of the control group at lth and 3th month after discharge,the difference was statistically significant (t =6.845,t =7.231,P <0.05).No significant difference in the re -admission rate (16.67%,6.67%)was found between the two groups (χ2 =0.387,P >0.05).The complication rate in the intervention group was significantly lower than in the control group at 3th month after discharge(χ2 =5.124,P <0.05).Conclusion Discharge planning and home care can effectively relieve depression and anxiety in patients with peritoneal dialysis and improve the abilities of daily life.It is worth promoting and applying in clinic.

Objective To study the relationship of cataract with lens epithelial cell apoptosis and autophagy by observing the ultrastructure of age-related and diabetic cataract lens epithelial cells.Methods Transmission electron microscope was used to observe the apoptotic and autophagic morphology of the lens epithelial cells in 5 cases with age-related and diabetic cataract respectively,and in 2 cases with normal lens.Results The apoptosis and autophagy of lens epithelial cells was found in cases with age-related and diabetic cataract,while no expression was observed in control lens epithelial cells.Conclusion The apoptosis and autophagy of lens epithelial cells are closely related to age-related and diabetic cataract formation.

?AIM: To evaluate the effects on recovering of corneal wound and postoperative discomfort of different methods for primary pterygium.?METHODS: Forty-seven cases ( 60 eyes ) of primary pterygium were excised under microscope with limbal epithelial transplantation, with sharp dissection ( 24 cases, 30 eyes, Group A) and blunt dissection (23 cases, 30 eyes, Group B).All cases were followed up for 1d to 1mo.?RESULTS: The recovering of corneal wound was better in Group B on 1st day and 3rd day after surgery.Pain, photophobia and tears, foreign body sensation were more serious in group A on 1st day after surgery with a statistically significant difference (P=0.005,0.015,0.012). Pain, photophobia and tears, foreign body sensation were more serious in Group A on 3rd day after surgery with a statistically significant difference ( P=0.019,0.018, 0.015).There was no statistically significant difference on 1wk and 1mo after surgery (P>0.05).? CONCLUSION: Compared with sharp dissection, primary pterygium excised with blunt dissection can significantly improve recovering of corneal wound and postoperative discomfort.

objective To explore the role of cytokines and dendritic cells (DCs) in rat high-risk corneal allograft survival pro- longed by superantigen Staphylococcal Enterotoxin B (SEB) and to compare the different effects between SEB and glucocorticoid. Design Experimental study.Participants Fisher 344 and Lewis rats.Methods The Fisher 344 and Lewis inbred rats were used for high-risk penetrating keratoplasty model.All of the Lewis rat recipients were divided into three groups by blinded fashion.GroupⅠand GroupⅡrats were injected intraperitoneally with 0.2ml saline buffer or SEB (75?g/ml) respectively at 4-day intervals on three occasions before transplantation.GroupⅢrats were injected subconjunctivally with 0.1ml dexamethasone (1mg/ml) daily from the first day after surgery for 2 weeks.The allograft survival was examined under slit-lamp.The concentration of interleukin IL-1?,IL-2,IL-4,IL-5,IL-6, IL-10,TNF-?in rat aqueous humor and peripheral blood were measured by liquichip and the cytokine and CD11c,CD80,MHC-Ⅱex- pression in corneal grafts were examined by immunohistochemestry staining.Main Octcome Measures Mean survival time of the allo- grafts,the level of cytokines in aqueous humor,peripheral blood and corneal grafts.Results Compared with group control,the grafts mean survival time was delayed about 3.8d in group SEB (P=0.00) and 7.1d in group dexamethasone(P=0.01).But there was no signifi- cant difference between group SEB and dexamethone (P=0.26).Liquichip test showed that the level of IL-1?in aqueous humor was re- duced and IL-4,IL-6 and IFN-?,ascended.Only IFN-?,and IL-6 could be found in peripheral blood,and the changing shift of them was similar to that in aqueous humor.The immunohistochemistry staining showed that the expression of IL-2 in rat corneal grafts was signif- icantly decreased but IL-4,IL-6 and IL-10 elevated.The expression of DCs in group SEB was similar to that in group control,which was elevated after keratoplasty,but the phenotype of DCs was not the same.There were predominantly mature DCs in group control while immature DCs in group SEB.Conclusions The immunological inhibiting effect of SEB is same to glucocorticoid,but the mecha- nism is different.SEB can modulate immune response,which might induce immune inhibition via the local production of cytokines and effect on DCs maturation involving corneal graft rejection prevention.
