Objective To investigate the methods of repair of the excessive width,theatrical fold line or multiple eyelid following blepharoplasty.Methods From Mar.2005 to Dec.2013,129 patients received repair because of their excessive width,theatirical fold line or multiple eyelid after blepharoplasty.Among them,75 cases were repaired 2 times,43 cases were repaired 3 times,7 cases were repaired 4 times and 4 cases were repaired 5-7 times before this operation.The case history ranged from 6 months to 12 years.The orbital septum fat flap,orbital free fat graft and orbital filling were utilized.Results The repair results were very satisfactory in 87 cases (67.4 ％),satisfactory in 32 cases (24.8％),basically satisfactory in 7 cases (5.4％) and not satisfactory in 3 cases (2.3％).Conclusions It is a simple and effective approach that orbital septum fat flap,orbital free fat graft and orbital filling are used to repair the excessive width,theatrical fold line and multiple eyelid.

Effects of oleanolic acid on immunoregulation were investigated in mice on the molecular level. Results showed that oleanolic acid could stimulate the biosynthesis or release of prostaglandins E2, F2? ( PGE2, PGF2? ) and cAMP, whereas had an inhibitory action on cGMP and histamine. Prostaglandins, cyclic nucleotides and histamine participate in many bodily functions, including regulation of blood pressure, immune function. It is suggested that their interaction may be of potential importance as a possible mechanism by which oleanolic acid acts in disease.

Experimental studies were made on enhancing effect of aloperine on PG-cyclooxyge-nase activity. Radioimmunoassay for determination of PGE2 and PGF2? contents was employed to evaluate PG-cyclooxygenase activity. Mice were given aloperine (50mg ? kg ? d-1) ip for 7d and the effects of lung and kidney homogenates on extrogenous arachidonic acid were studied. The results suggest that biosynthesis of PGE2, PGF2? be obviously increased in the experimental than that of control, suggesting of aloperine showing enhancing effect on PG-cyclooxygenase activity.

s Objective To observe the enhancement of sensitivity of human gastric cancer cell MKN-74 to anticancer drugs by administration of 5-aza-2'-deoxycytidine(5-Aza-CdR)and trichostatin A(TSA)with anticancer drugs.Methods Growth inhibition of MKN-74 with treatment of 5-Aza-CdR and/or TSA together with anticancer drugs,including fluorouracil(5-FU),paclitaxel(PTX),oxaliplatin(OXA),SN38 or gemcitabine(GEM),was detected by MTT method.Induction of apoptosis was analyzed by flow cytometry.Expressions of p21,caspase3,Rb and p16 gene were studied by RT-PCR.The gray scale of the genes was analyzed by gel analysis software Bandscan 4.3,and the ratio of gray scale of targeted genes and GAPDH gene were calculated.Results Compared with 5-Aza-CdR alone,combined administration of 5-Aza-CdR and TSA enhanced the chemosensitivity of MKN-74 to 5-FU,PTX,OXA and GEM.Compared with TSA alone,the combined administration enhanced its osensitivity to OXA and GEM.The apoptosis rates in MKN-74 cells in TSA+OXA group,5-Aza-CdR+OXA group and 5-Aza-CdR+TSA+OXA group were 28.067%,25.333% and 38.367%,respectively(P

Urokinase-type plasminogen activator plays an important role in the dissolution of clot and the treatment of thrombosis diseases. Presently, more attention has been paid to urokinase metabolism in human body and the relationship between urokinase fibrolysis effect and its receptor in endothelial cell.Cultured endothelial cell was used in the experiment to react with labelled urokinase in the presence or absence of unlabelled urokinase. It was found that the specific bindind of labelled urokinase with endothelial cell increased with the increasing concentration of labelled urokinase and reached the saturation point from 10 to 32 ?g labelled urokinase/ ml. The maximal binding sites with urokinase per cell were 1.4?10?, and Kd value 7.5? 10~(-12)M, Meanwhile, PMA-treated endothelial cell was used to react with ~(125)I-uPA at the same conditions as discribed above. Compared with the specific binding of DMSO-treated endothelial ceil, the maximal binding sites per PMA-treated cell increased from 1.4?10~6 Per untreated cell to 2.2?10~6, and the Kd value from 7.5?10~(-12)M to 9?10~(-12)M.These results showed that urokinase receptor exists on the surface of endothelial cell, and that the number of receptor per cell could be modulated by PMA. It is possible that the urokinase binding with endothelial cell can play an important role in the very short half-life of urokinase in human body.

In the undergraduate teaching assessment,"eaching quality control" is the core content of their inspection.This paper explained the quality control of the content,analyzed the challenge of improving the teaching quality and put forward the idea of constructing the perfect teaching quality control system from five aspects such as raising awareness and unifying thinking,establishing a sound teaching system,strengthening the organizational functions and responsibilities,grasping the key points and implementing the whole process of the quality control.

The blockade of targeted immune checkpoint is one of the most promising approaches to activate therapeutic antitu-mor immunity. The immune checkpoint refers to a plethora of inhibitory pathways in the immune system. These pathways are crucial for maintaining self-tolerance and modulating the duration and amplitude of physiological immune responses in peripheral tissues to minimize collateral tissue damage. Tumors co-opt certain immune-checkpoint pathways as a major mechanism of immune resistance. Cytotoxic T-lymphocyte-associated antigen 4 antibodies were the first of this class of immunotherapeutics to acquire approval from the US Food and Drug Administration. Preliminary clinical findings with blockers of additional immune-checkpoint proteins, such as pro-grammed cell death protein 1, indicate broad and diverse opportunities to enhance anti-tumor immunity with the potential to produce du-rable clinical responses. Classic chemotherapy exerts significant immunomodulatory effects on tumor cells via multiple mechanisms. Therefore, the combination of immunotherapy, including immune checkpoint blockade with chemotherapy, is a new promising trend in anti-tumor immunotherapy.

OBJECTIVE:To study the protective effects of Ginkgolides(GL)on cerebral ischemia in experimental rodents. METHODS:The models of decapitative mice and acute incomplete cerebral ischemic(AICI)rats were used.The gasp duration of decapitative mice and cerebral index,water content of brain,cerebral capillary permeability and hemorrheological parameters in rats were determined.RESULTS:Ginkgolides could prolong gasp duration of decapitative mice,increase the cerebral index and the water content of brain,inhibit capillary permeability,improve hemorrheological parameters and decrease blood viscosi?ty.CONCLUSION:Ginkgolides may antagonize the damage of cerebral ischemia.
