Objective To observe the bleeding risk of short-term intensive statin therapy after coronary artery bypass grafting. Methods A total of 240 patients treated with coronary artery bypass grafting were randomly divided into group A(experimental group)and group B(control group). All pa-tients were normalized to conventional treatment and they were given low molecular weight heparin for an-ticoagulant therapy during the perioperative period. Patients in group A were given 40 mg of atorvastatin before surgery,and 40 mg of atorvastatin every night for one month after the surgery. Patients in group B were given 10 mg of atorvastatin every night during the treatment. One month after the operation,platelet aggregation rate and bleeding events of patients were compared. Results There were significant differ-ences in maximum platelet aggregation rate[(14. 5 ± 3. 7)% vs(38. 1 ± 7. 4)% ,P < 0. 05],inhibition rate of platelet aggregation[(79. 5 ± 4. 3)% vs(50. 8 ± 10. 2)% ,P < 0. 05],and incidence of postopera-tive bleeding[27. 5% vs 12. 5% ,P < 0. 05]between group A and B,respectively. Conclusion Short-term intensive statin therapy can increase the bleeding risk after coronary artery bypass grafting.

objective: To investigate the effect of human serum albumin(HSA)on the attachment of human gingival epithelial cells(HGEs)to commercial pure titanium(cpTi).Methods: HGEs were cultured, the cells of passage 2～5 were seeded on to cpTi samples which were preincubated in keratinocyte serum free medium with 50 mg/ml HSA or without HSA. Cell attachment was studied by immunofluorescence analysis.Results: HGEs were cultured and identified by positive expression of cytokeratin. 4,12 and 24 h after seeding attached cells on HSA preincubated cpTi were 218,730 and 849, those on the control 417,745 and 864, respectively.Conclusion: The early stage of cell attachment of HGEs on to cpTi may be inhibited by HSA.

Objective To investigate the effects of EGB on hepatic fibrosis and expression of Activin A in rats with fibrosis.Methods From Oct.2004 to Apr.2005,the study was conducted in 30 adult male rats in the pepartment of Gastroenterology,the people's Hospital of Wuhan University.The rats were randomized into 3 groups:control group,model group and treatment group.Except the rats in the control group,others were induced to hepatic fibrosis by intraperitoneal injection of CCl_4 twice a week for 8 weeks.Those rats in the treatment group were intragastrically administered with EGB establish model of everyday.At the end of the 8th week,all rats were sacrificed.The samples of liver was staining with HE.The expression of Activin A was determined by immunohistochemistry and RT-PCR.Results The grade of fibrosis in EGB-treated groups were lower than that in the model group(P

Objective To promote the level of early diagnosis and strengthen the understanding of pathogenesis, pathological staging and prognosis of primary gallbladder carcinoma (PGC). Methods The data of 679 patients with PGC treated in our hospital from 1956 to 1998 were retrospectively analyzed. Results The incidence of PGC has been increasing in recent years while the surgical management for the disease was not satisfactory. Upon diagnosis, most patients were with PGC in advanced stage. PGC was usually found among the aged woman patients. The female/male ratio was 3∶1. There was a close relationship between gallstone and PGC, for the gallstone was found in 60% of the patients with PGC. The diagnostic accordance rate before and after operations was low. Most cases of PGC were found unexpectedly during operation due to gallstone or acute cholecystitis. It was even worse that many patients with PGC missed the opportunity of diagnosis and treatment because doctors noticed the gallstone only. Pathological classification revealed that most cases of PGC were of adenocarcinoma. Development in imaging medicine might help a lot in finding early-stage cases and improving prognosis. Conclusions Strengthening the understanding of pathogenesis, pathological staging and prognosis of the disease and proper use of various examinations are the basic means of obtaining early diagnosis and improving the prognosis.

Objective To explore the features of clinical manifestations and electrophysiology of spinal muscular atrophy(SMA) in children.Methods The clinical features and laboratory data were analyzed in 32 children with SMA,electromyography tests were carried out in 28 patients and the muscle biopsy were performed in 24 cases.Results The 32 cases were subdivided into 3 clinical groups,15 cases were SMAⅠ,12 cases were SMAⅡ,5 cases were SMAⅢ.They were all characterized by progressive muscle weakness associated with hyptonia and atrophy.The clinical distinction between SMAⅠto SMAⅢ reflected different age of onset and disease severity.All cases of SMAⅠhad symptoms of respiratory disability,only 1 case of SMAⅡ had paradoxical breathing and none of SMAⅢ had similarly symptoms.Electromyographic studies showed a pattern of denervation with no sensory involvement.The rate of spontaneous potential was 87%,with gentle strain,the duration of motor unit was extended(30%-150%) and the amplitude of it was increased(90%-450%),the motor nerve conduction velocity was reduced slightly in 28% patients.The muscle biopsy provided evidence of skeletal muscle denervation with groups of atrophy.Conclusions The clinical features,the changes of electromyography and the muscle biopsy are valuable for diagnosis of SMA.Respiratory management will prolong survival and improve the quality of life for these patients.

Objective To optimize the preparation of high-efficiency galactocylated poly-L-lysine (Gal-PLL) ligand of the asialoglycoprotein receptor in liver, providing premise and foundation for upper preparation of ultrasound contrast agent of liver targeted nanoscale perfluorocarbon microballoon and the liver targeted molecular imaging. Methods Chemical reactions of reductive amination were carried out on group A and group B according to different proportions of reaction component. Each group was subdivided into three subgroups. In group A, three different molar ratios of D-galactose and poly-L-lysine (PLL) were compounded respectively with equivalent and sufficient reductant borohydride. In group B, identical molar ratios of D-galactose and PLL were compounded respectively with three unequal reductants borohydride. Products of each group were separated and purified by sephadex column to acquire different molecular weight distributions and the results were analyzed. Results In the condition of identical reductant, the peak curve of compound's molecular weight appeared earlier when D-galactose decreased properly. In the condition of identical molar ratio of D-galactose and PLL,the peak curve of compound's molecular weight appeared also earlier when reductant decreased properly. When the molar ratio of D-galactose and reductant was 1∶1, the peak curve of compound Gal-PLL and free components was more obvious, and the quantity of compound Gal-PLL increased to maximum. Conclusions In the condition of identical reductant, coupling effect of D-galactose and PLL increased when D-galactose decreased properly. In the condition of identical molar ratio of D-galactose and PLL, coupling effect was better when reductant decreased properly. When the molar ratio of D-galactose and reductant was 1∶1, coupling effect of them was the best. The coupling of D-galactose and PLL was related to not only the proportion of D-galactose and PLL, but also the proportion of D-galactose and reductant.

Objective: To study the rat intestinal absorption characteristic of puerarin loaded O-carboxymethyl chitosan (CMCS) microspheres in situ. Methods: Single-pass intestinal perfusion (SPIP) model was used for rat in situ and HPLC to determine the concentration of puerarin. The effects of different perfusion rate, drug concentration, and intestinal segments on intestinal absorption were investigated, and the absorption characteristics of the puerarin and puerarin loaded O-CMCS microspheres were compared. Results: Perfusion rate had significant effect on the absorption rate constants (Ka) and the apparent absorption coefficient (Papp) (P < 0.05); The concentration of puerarin in perfusate had no significant effect on Ka and Papp (P > 0.05); Ka and Papp of drug loaded microspheres in jejunum and ileum showed no significant difference, but they were significantly higher than that in duodenum (P < 0.05); The drug loaded microspheres and puerarin had the significant difference in Ka and Papp in jejunum (P < 0.05). Conclusion: The absorption mechanism of puerarin in the microspheres is passive diffusion, puerarin is absorbed well in jejunum and ileum, and puerarin loaded O-CMCS microspheres can significantly improve the absorption of puerarin.
