The most common cause of glaucoma filtration surgery failure is cicatrization secondary to fibroblast proliferation and of collagen. The high-risk factors for filtration failure include young age, aphakia, inflammation, neovascularization, and previous failure of filtration operation. Studies have shown beneficial effects of a single dose intraoperative mitomycin C,an antimetabolite, in inhibiting fibroblast proliferation and slceral wound cicatrization, thereby promoting success in eyes of poor surgical prognosis. Corneal complications have been minor.

Objective To study the effects of static magnetic field (SMF) on development of rat embryonic spinal cord neurons. Methods Primary cultured embryonic spinal cord neurons of Wistar rat were exposed to 1.0, 10.0, 50.0, 100.0 and 200.0 mT static magnetic field. The morphological structure, cell's differentiation and proliferation of the embryonic spinal cord neurons were observed and the contents of MDA, superoxide dismutase (SOD) and protein contents in the neurons were determined. Results Static magnetic field at density of 50-200.0 mT could inhibit the differentiation and proliferation of the cells and the phenomena such as cell aggregation, detouchment of some cells, decrease of clone-formation rate and the size of the cells were observed. The contents of MDA in the cells were increased, while the activities of SOD and the level of protein were decreased. Conclusion Static magnetic field might damage the development of embryonic spinal cord neurons by enhancing the lipid peroxidation.

Objective To study the percentage and the distribution of nosocomial infection, and susceptibility of related pathogens to antibiotics in patients with systemic lupus erythematosus (SLE). Methods The clinical data of in patients with SLE in our hospital from June, 1990 to June, 1998 were analyzed. The susceptibility of the pathogens to antimicrobial agents was tested by K-B paper dilution method. Results The percentage of nosocomial infection in these cases was 16.1％ . The major pathogens were staphylococcas aureus, Escherichia coli and Candida. The most highly resistant microbes were E.coli, S.arueus and Pseudomonas aeruginosa. Conclusions The nosocomial infection is one of the most common complication of SLE in the in patients. It is necessary to examine the pathogens regularly and use antibacterial agents according to the susceptibility.

Objective To evaluate the effect of endothelin A receptor antisense oligodeoxynucleotides (ETAR-ASODN)on the growth of human prostatic stromal cells. Methods Primary cultured prostatic stromal cells were derived from patients with benign prostatic hyperplasia (BPH).The cells of passages 4～6 were routinely used for this study after identification.ETAR-ASODN at the concentrations of 5,10 and 15 ?mol/L were added into the culture cells with lipofectin, and cell proliferation was measured by MTT assay. The expression of ETA receptor was tested by 125 I-ET-1 radioligand banding assay. Results MTT assays showed a significant decrease in cell proliferation in stromal cells after 5,10 and 15?mol/L ETAR-ASODN were added with the A 540 values being 0.304?0.082,0.296?0.008 and 0.194?0.061,respectively.The proliferative activity was significantly decreased compared with control group ( P

The personnel training is one of the core tasks of clinical Chinese pharmacy.Since the professional training of clinical Chinese pharmacy has started relatively late in China,the teaching contents and curriculum still need further improvements.This paper is aiming at analyzing the post tasks of personnel of clinical Chinese pharmacy,defining the knowledge structure of them,and learning from the characteristics of clinical Chinese pharmacy teaching systems of the foreign and domestic universities.On such basis,the paper proposes the ideas about constructing the curriculum system of clinical Chinese pharmacy,to provide a reference for the higher educational personnel training of clinical Chinese pharmacy.

Objective To study the prevention and treatment of intra- or post- operative complications of radiofrequency ablation (RFA) for hepatic malignancy. Methods A series of 353 patients with primary hepatic carcinoma or secondary hepatic malignancy verified by pathological examinations and clinical manifestations underwent 452 times of RFA between October 1999 and March 2003, including 344 cases of percutaneous RFA and 9 cases of RFA during open surgery. There were 198 cases of primary hepatic carcinoma previously unoperated, 81 cases of recurrent hepatic carcinoma after surgery, and 74 cases of secondary hepatic malignancy. All the patients were followed up to make out short- or long-term surgical complications. Results Complications happened in 12 cases: skin burn by the electrode (2 cases), pneumothorax (1 case), right hydrothorax (1 case), vena cava thrombus (1 case), right bile duct injury and stricture (1 case), gastric external fistula (1 case), bile leakage in the left lateral lobe of the liver (1 case), hepatic abscess (1 case), external fistula of the ascending colon resulted from hepatic abscess (1 case), internal fistula of the duodenum, liver and right thorax resulted from hepatic abscess (1 case), and intra-abdominal hemorrhage (1 case). The incidence of complication was 2 65% (12/452) and the complication-related mortality was 8 33% (1/12). Conclusions RFA is a kind of minimally invasive procedure. But RFA especially percutaneous RFA may involve some risks for patients with the tumor located at the porta hepatic or the surface of the liver, or adhered to hollow organs, especially those who had a history of abdominal operation and adhesions of hollow viscera to the liver. Some complications can be prevented and effectively treated in the event of proper selection of patients, careful performance during the surgery, intensive postoperative care, effective hemostasia and efficient infection prevention.
