Objective The aims of this study were to investigate the prognostic value of CEA and CA19-9 expression in advanced gastric cancer and the prognostic factors of advanced gastric cancer.Methods A total of 255 patients with advanced gastric cancer who underwent radical R0 radical surgery were enrolled in the Department of Gastrointestinal Surgery,Harbin Medical University Cancer Hospital from January 2010 to December 2010,and were divided into group A(CEA<2.19ng/mL and CA19-9<10.78U/mL),group B(CEA≥2.19ng/mL or CA19-9≥10.78U/mL)and group C(CEA≥2.19ng/mL and CA19-9≥10.78U/mL).These groups were analyzed the differences in gastric cancer patients with clinical pathology and survival,and prognostic factors of patients with advanced gastric cancer factors.Results There were statistically significant differences in clinical N staging,clinical TNM staging and pathological TNM staging in three groups of patients with advanced gastric cancer(P<0.05).There was no significant difference in the median survival time in three groups of patients with advanced gastric cancer(P>0.05).The 1-year,3-year and 5-year survival rates of group A were higher than those of group B and group C(P>0.05).The factors affecting the prognosis of gastric cancer included the degree of tumor differentiation,pathological T staging,pathological TNM staging,the total number of lymph nodes,the number of positive lymph nodes and lymph node metastasis.Conclusion Combined detection of CEA and CA19-9 expression indicates a certain reference value for prognosis of gastric cancer.

Objective To study the mechanism of acupuncture combined with herb decoction for brain occlusion. Methods one-side middle cerebral artery occlusion (McAo) rat by ehermoregulation was used as focal cerebral ischemia experimental animal. All animals were divided into four groups as model group, acupuncture group, herb decoction group, acupuncture combined with herb decoction group. And the dynamic changes of c-fos protein in ischemia region of brain tissue after treatment were observed. Results All of acupuncture group, herb decoction group and combining group could enhance the expression of c-fos protein in all stages of ischemia, and combining group was enhanced significantly. Conclusion Compared with herb decoction or acupuncture, the method of acupuncture combined with herb decoction could improved the stress ability of nerve cells of acute brain ischemia by enhance the content of c-fos protein significantly.

AIM:To discuss the related factors that affected the stability of posterior corneal surface after laser in situ keratomileusis ( LASIK) .
METHODS:About 64 patients (64 eyes) were enrolled. The correlation among the changes in posterior corneal surface 6 month after LASIK, surgery method, corneal flap thickness ( FT ) , ablation thickness ( AT ) , postoperative residual corneal stroma thickness ( RCST ) , preoperative thinnest corneal thickness ( CT ) , flap thickness/preoperative thinnest corneal thickness ( FT/CT ) , ablation thickness/preoperative thinnest corneal thickness ( AT/CT) , postoperative residual corneal stroma thickness/preoperative thinnest corneal thickness ( RCST/CT) , anterior and posterior preoperative corneal height, the difference of the forward shift in posterior corneal surface ( diff value ) of preoperative and preoperative intraocular pressure were analyzed.
RESULTS: The changes of diff value between preoperative and postoperative were related with diopter (r=0.419, P=0.014), AT (r=0.394, P=0.023), AT/CT (r=0.501, P=0.004), Diff value of preoperative (r=0.501, P=0. 004), RCST (r=-0. 385, P=0. 033) and RCST/CT (r=-0. 401, P=0. 025). The changes of height value from posterior corneal surface between preoperative and postoperative were related with diopter (r=0. 520, P=0. 002), AT (r=0.504, P=0. 003), AT/CT (r=0. 442, P=0. 013), Diff value of preoperative (r=0. 624, P=0. 000) and RCST/CT (r=-0. 394, P=0. 028).
CONCLUSION: AT, RCST, AT/CT, RCST/CT and diff value of preoperative should be the key index that predicted the stability of posterior corneal surface after LASIK,the further research will give the range of safety value.

AlM: To explore the clinical significances and changes of related parameters of corneal endothelial cell in keratouveitis patients before and after treatment.
METHODS:Fifty-two keratouveitis patients ( 52 eyes ) diagnosed and treated in our hospital from October 2012 to December 2013 were collected. Before and after treatment, the related parameters of corneal endothelial cell in all patients were measured with non - contact corneal specular microscope and these parameters were statistically analyzed.
RESULTS: Compared with the normal group, obvious endothelial cell edema and great variation was observed in diseased group. The shorter duration of treatment, the better the recovery of endothelial cells and the fewer cells lose. Conversely, the longer the healing of normal hexagonal cell ratio was smaller, the larger the coefficient of variation. Before and after treatment, the differences of each parameter were statistical significance (P<0. 05).
CONCLUSlON: The functional recovery of corneal endothelial cell has directly relation with disease times.

AlM: To research the characteristics of positive relative accommodation ( PRA) , negative relative accommodation (NRA) and PRA/NRA ratio in myopes. To analyze the relationship among PRA, NRA, PRA/NRA ratio, spherical equivalent degree, years and habbits of wearing glasses, myopia development, and pupil diameter.METHODS: Aretrospective study of ninety eyes in the 180 th Hospital of Quanzhou from August 2014 to December 2014. PRA, NRA and PRA/NRA ratio were compared among low, moderate, high myopes and emmetropes. The correlation were analyzed among PRA, NRA, PRA/NRA ratio, spherical equivalent degree, years and habbits of wearing glasses, myopia development and pupil diameter. PRA, NRA, PRA/NRA ratio, years and habbits of wearing glasses and pupil diameter were compared between progress group and non-progress group.RESULTS: ( 1 ) Without statistical differences in age, sex and intraocular pressure, PRA and PRA/NRA ratio of myopes were lower than emmetropes, while NRA was higher. (2) Without statistical differences in age, sex and intraocular pressure, PRA, PRA/NRA ratio and NRA had no statistical differences while years and habbits of wearing glasses had statistical differences among low, moderate, high myopes. ( 3 ) With longer years of wearing glasses, PRA, PRA/NRA ratio were larger and NRA, pupils were smaller. ( 4 ) Without statistical differences in age, diopter and intraocular pressure, one group which were not easy to deepen degree had more often-wear-glasses myopia patiens and longer years of wearing glasses, the other group which were easy to deepen degree had more seldom-wear-glasses myopia patiens and shorter years of wearing glasses.CONCLUSlON: PRA and PRA/NRA ratio of myopes were lower than emmetropes, while NRA was higher. No correlated relation was detected among PRA, NRA, PRA/NRA ratio, spherical equivalent degree and myopia development. lt suggests the onset and progress of myopia are related to many factors. Wearing-glass timely and accurately can release the decline of PRA and PRA/NRA ratio and slow down degree development in myopes.
