Chinese Ophthalmic Research 2009;27(11):1019-1022
Objective Antiphospholipid antibody and factor Ⅻ deficiency are among the coagulation disorders that have been implicated in many thrombembolic events. The aim of this study was to investigate the prevalence of antiphospholipid antibodies and factor Ⅻ deficiency in patients with retinal vein occlusion (RVO). Methods The investigation was a case control study. The periphery blood was collected from a cohort of 33 consecutive patients with RVO and 30 age- and gender-matched normal subjects. Anticardiolipin antibody (ACA) was detected by ELISA as binding index (BI) =A value/standard A value. The lupus anticoagulant antibody was examined by APTT test and the activity of factor Ⅻ was detected. This study was approved by The Human Research Ethics Committee of this hospital, and written informed consent was obtained from all the subjects before initiation of any study protocol. Results The total positive rate of APA in RVO group was 24. 24% (8/33), showing a insignificant difference in comparison with control group (6. 67%, 2/30) (P = 0. 085). The positive rate of anticardiolipin antibody in RVO group was 18.18% (6/33), presenting an obvious enhance in control group (P = 0. 025) . Three patients in RVO group disclosed positive response for IgG-anticardiolipin antibody, one patient for IgM-anticardiolipin antibody, two patients for both isotypes IgG and IgM anticardiolipin antibodies, and two patients revealed positive reaction for lupus anticoagulant antibody. The presence of lupus anticoagulant antibody among the patients with ≤ 50 years and > 50 years was similar to that in age-matched controls (P =0. 160, P =0. 206). Factor Ⅻ deficiency was found in 14 of 33 patients(42. 42%) and in 4 of 30 controls(13. 33%) (P = 0. 013). The prevalence of factor Ⅻ deficiency among the patients with ≤50 years and > 50 years was similar to that in age-matched controls (P = 0. 206, P = 0. 052) . Conclusion Our results indicate that the prevalence of ACA and factor Ⅻ deficiency in RVO patients appears to be correlated.

China Pharmacy 2016;27(20):2813-2815
OBJECTIVE:To investigate the effects of early before PCI and immediate application of tirofiban on coronary blood flow and myocardial perfusion in patients with high risk acute coronary syndrome (ACS). METHODS:100 high risk ACS patients were randomly divided into observation group and control group,with 50 cases in each group. Two groups were given tiro-fiban;observation group was given medicine 10 μg/kg within 3 min,4-6 h before PCI,with the velocity of 0.15 μg/(kg·min)till 24 h after PCI. Control group was given medicine at the beginning of PCI,route of administration was same as observation group. The incidence of TIMI blood flow grading,TIMI myocardial perfusion grade (TMPG),cTn Ⅰ,PAR and main adverse cardiac events(MACE)were compared between 2 groups before and after treatment. RESULTS:After operation,the patients of 2-3 grade TIMI blood flow and 2-3 grade TMPG in 2 groups were significantly more than before;the patients of 2-3 grade TMPG in observa-tion group was significantly more than in control group,with statistical significance(P<0.05). After treatment,cTn Ⅰof 2 groups were significantly increased,while PAR were significantly decreased,with statistical significance compared to before operation (P<0.05);but there was no difference between 2 groups (P>0.05). There was no statistical significance in the incidence of MACE between observation group(8.0%)and control group(16.0%)(P>0.05). CONCLUSIONS:Early application of tirofiban before PCI can effectively improve coronary blood flow and myocardial blood supply in high risk ACS patients.

Acta Anatomica Sinica 1955;0(03):-
Ontogenesis of gastrin cells (G cells) and somatostatin cells (D cells) in the gastrointestinal tract was studied by PAP and indirect immunofluorescence method in sixty human fetuses aged 8-38 weeks of gestation. The appearance of D cells and G cells was observed as early as 8-9 weeks of gestation. These cells were not seen in the submucosa and the tunica muscularis except the epithelium of gut. After 12 weeks of gestation, D cells can be found in the mucosa of the whole gut, whereas G cells only in the mucosa of the antrum and small intestine. The distribution, number and the ratio of G cells to D cells were also examined. In addition, we have observed that G cells in the antral mucosa often possessed processes which were considered to have paracrine function. The G cells and D cells were open-type endocrine cells in the human fetal gut except the D cells in the fundic mucosa. The possible function of G cells and D cells in the development of gut was discussed. The ratio of the two cell types in adult human antrum and upper duodenum has also been compared with that of fetus.

Acta Anatomica Sinica 1955;0(03):-
By means of ATPase histochemistry and OKT-6 immunogold-silver staining, it was demonstrated that Langerhans ceils (LC) were present in the epithelia of human skin, palatine tonsil, ectocervix and esophagus. In the skin LC were located mainly in the stratum spinosum of the epidermis. There were some LC in the hair follicle and duct of sebaceous gland, and a few in the dermis and around sebaceous gland acinus. In the tonsil, ectocervix and esophagus, LC were located mainly in the middle layer of epithelia. No LC were found in the lymphoid follicle and thymus-dependent zone of the tonsil, and no LC in the lamina propria of ectocervix and esophagus. ATPase histochemistry was also used to examine the distribution of epidermal LC in normal human skin of various ages and various anatomic regions. This study showed that the density and morphology of epidermal LC varied with age and different anatomic regions of human body. Statistical analysis indicated that LC density in various age groups was as follows: fetus
8.THE ARGYROPHIL CELLS IN RAT GASTROINTESTINAL TRACT——A COMPARATIVE STUDY BETWEEN IMMUNOHISTOCHEMICAL AND SLIVER IMPREGNATION TECHNIQUES
Acta Anatomica Sinica 1954;0(02):-
The aim of this study is to investigate comparatively the relationship between the endocrine and argyrophil cells in the rat gastrointestinal tract by means of the IGS, PAP immunohistochemical and Grimelius technique in the same sections. The results showed that the SS cells and almost G ceils can not be identified by Grimelius technique. The Grimelius technique had high specifity to reveal EC cells in the antrum of stomach and the intestine. Our technique is relatively simple and reliable, and may be used for consecutive demonstration of argyrophil cells and bioactive peptide-containing cells.
