Fluorescent staining method is a sensitive cytochemical staining method, it can reflect minimal changes of biochemical components of cells. The 7690-Xu fluorescent staining solution prepared with thioflavine can show the heterogeneo- us fluorescence of cells in different stages of differentiation. The younger cells with low degree of differentiation show blue fluorescence, the lower the degree the deeper the color. Along with the differentiation of cells, the blue color of fluorescence deflects to the red color of spectrum gradually, the blue color of fluorescence of cytoplasm changes gradually to bluish, bluish-green, and finally yellow color. The blue color of fluorescence of nucleus changes through greyish- blue to orangeyellow or orange-red.The cytoplasm of cells in various organs with high degree of differentiation appears yellow, and the nucleus orange-yellow or orange-red in color.

Objective To identify the configuration of the fascial sheath of the sciatic nerve in the adult pelvis . Methods A total of 14 cadaveric pelvic specimens and 20 living subjects were used for cadaveric examination and magnetic resonance imaging ( MRI) observation , respectively .The cadaveric specimens were investigated by the local latex injection method ( n =10 ) sectional anatomy ( n=2 ) or histological staining methods ( n =2 ) .The MR images were collected and analyzed from twenty patients without pelvic disorders .Results The injected latex did not diffuse along the pelvic segment of the sciatic nerve .Sectional anatomical and histological data showed that the architecture of the fascial sheath of the sciatic nerve varied at different levels .An intact circular sheath around the nerve was rarely observed .There was no fascia barrier between the obturator and sciatic nerves .Appearance on MRI was consistent with the cadaveric observation.Conclusion No intact fascial sheath exists along the pelvic segment of the sciatic nerve , thus sciatic anesthesia may block the obturator nerve .

This article reviews the resultsof the basic research about epidermal growth factor and its receptor,and the development of the novel drug, EGF eyedrop, that containing chemically synthesised EGF gene,the construction of EGF expression vector, the transformation of the host cells , the purification of the recombinant protein EGF, the preparation of three batches of the EGF product and identification, the preclinical and clinical trials. Relevant studies show that recombinant EGF consisting of 51 amino acids can be secreted into the medium under the control of the α factor leading sequence in the yeast cells.The EGF can accelerate the growth of corneal-limbal epithelial cells and the healing of an alkali burned corneal. The EGF can be used in curing oral cavity ulcer and skin burned wound. And it has the preventive effects on experimental duodenal ulcer of rat. The antiserum was made for test of the con- centration of blood EGF and urine EGF by RIA. Data from studies demonstrate the inhibition effect of EGF on the growth of tumor cells, such as A431 and BT325 cells in the presence of high EGF concentration (＞10 ng/ml). The expression of EGFR and DNA ploidy in renal carcinoma has clinical significance. Crystallization and preliminary x-ray diffraction studies of the EGF has been made. The MW of the EGF product is 6000, and the pI is about 4. 6 and it has correct N-terminal amino acids sequences , immunogenicity and biological activity. There is no vestige of the DNA of the yeast cells. Animal experiments reveal that there is no cumulation of the EGF in the body, and EGF can promote corneal epithelial healing. There is no toxicological effect during cornea wound healing of rabbit. A randomized, double-blind, placebo-controlled, multi-center clinical trial was conducted in four hospitals to assess safety,ocular tolerance and efficacy of an ophthalmic solution of EGF for 200 cases of cornea transplantation and 247 cases of nebulae. Unequivocal results were obtained as the eyedrop really accelerate the wounded cornea healing. So, the EGF eyedrop as a novel drug of class I is approved by the National Drug Administration, and this is the first gene engineering drug that come from yeast expression system in China.

Objective To observe and assess the effect of different dosages of aspirin on inflammatory biomarkers, hemorheology (platelet aggregation rate) and clinical prognosis in patients with acute coronary syndrome ( ACS). Methods ACS patients were randomly assigned to receive different dosages of aspirin treatment orally. Patients in group A,B and C took 100 mg, 500 mg and 1000 mg of aspirin per day respectively. They were treated and followed-up for 1 year. High-sensitivity C-reactive protein ( hsCRP) , IL-6, tumor necrosis TNFot and platelet aggregation rate were examined and major adverse cardiac events( MACE) were recorded. Results A total of 312 patients with ACS were enrolled in the study. The baseline characteristics of the three groups were not different with respect to age, gender, cardiovascular risk profile, level of inflammatory biomarkers and concomitant treatment before and after randomization. The levels of baseline serum hsCRP, IL-6 and TNFa were higher in subjects of the study as compared with normal reference value (P<0. 05, <0. 05, <0. 01) and they decreased significantly after therapy with 3 different doses of aspirin (detected at 30 days, 6 months and 12 months, P <0. 001 ) , but there were no significant differences among the three groups( P >0. 05) . Rehospitalization , MACE and the change of platelet aggregation ratio were not significantly different among the three groups. The incidence of gastrointestinal complaints was significantly higher in groups B and C than in group A ( P < 0. 05 ). Conclusions The levels of serum inflammatory biomarker increase in patients with ACS. Aspirin therapy may decrease the level of inflammatory markers significantly, but increasing the dosage of aspirin from 100 mg to 1000 mg daily does not decrease the level of inflammatory markers and the clinical MACEs further. However, the incidence of gastrointestinal complaints increase significantly with the increase of aspirin dosage.
