Results After two weeks of minirin therapy,the average daily urine volume decreased from 7985.40 ±410. 36 ml to 2277. 87 ± 328. 94 ml,and the average plasmas osmolarity increased from 301. 68 ± 3. 59 ml/d to 313. 26 ±4. 87 mOsm/ kg. No adverse reaction was observed during the therapy. Conclusions Minirin is effective and safe in the therapy of postoperative transsphenoidal surgery patients with central diabetes insipidus.

Objective　To analyze the influence of multiple variable factors on the occurance rate of pneumothorax associated with transthoracic needle aspiration biopsy of the lung. Methods　Fluoroscopically guided lung biopsies were performed in 46 patients. Variable factors were analyzed including lesion size, location, number of puncture, presence of emphysema and patients position after needle biopsy of the lung. Results　Pneumothorax occurred at 9 (19.6%) of 46 patients and that occurred at 4 (44.4%) of 9 emphysematous patients. Among them 2 necessitated chest drainage tube placement. The pneumothorax occurance rate was 30% (3/10) for lesions of diameter 3cm or less in size. In the dependent group, pneumothorax occurred in 4 of 20 patients (20%). In the nondependent group, pneumothorax occurred in 5 of 26 patients (19.2%). Conclusion　The correlation showed that increasing frequency of pneumothorax with decreasing size of lesions. An increased rate of pneumothorax was correlated with presence of emphysema. Patients with emphysema are more likely to have a symptomatic pneumothorax. No significant differences were found in the incidence of pneumothorax between patients placed with the puncture site dependent after biopsy and those placed with the puncture site nondependent.

Objective To evaluate the killing effects of oxymatrine(OM) on human colon cancer cell line SW1116 and the mechanism of its anti-neoplastic effect. Methods Methyl thiazolyl tetrazolium analysis, flow cytometry , polymerase chain reaction(PCR)-enzyme linked immunosorbent assay (ELISA) and RT-PCR were used to detect the killing effects of OM and its influence on cell cycle dis- tribution , telomerase activity, expressions of human telomerase reverse transcriptase (hTERT), c-myc ,p53 and mad1 genes in SW1116 cells. Results OM exhibited dose-dependent killing effects on SW1116 cells and induced the increase of G1/G0-phase cells and decrease of S-phase cells. It was found that OM could supress the telomerase activity of SW1116 cells, and the effects were dose- and time-dependent. After OM administration, the expression of hTERT gene in SW1116 cells was decreased, those of p53 and mad1 genes were increased, and the expression of c-myc gene had no marked changes. Conclusions OM has dose-dependent killing effects on SW1116 cells.The anti-neoplastic activity of OM might be due to the inhibition of telomerase activity by means of its influence on hTERT and the up-stream regulation genes.
