Objective To investigate the arterial injury in vitro porcine kidney to different size of nephrostomy tracts. Methods The technique of percutaneous nephrostomy was applied to establish 11 groups of different size of nephrostomy tracts from 12 F to 32 F,with 40 tracts in every group.The technique of digital subtraction angiography (DSA) was used to inspect and analyze arterial injury. Results In the range from 12 F to 32 F,the damage of arterial injury increased with the size of the tract diameter.In groups of 20 F and 32 F,the number of nephrostomy tracts with serious arterial injury was 18 (18/40) and 30 (30/40) respectively,and the difference was statistically significant (P＜0.05).There was no statistical difference between groups 18 F、20 F、and 22 F. Conclusions The damage of renal arterial injury increased with the size of the nephrostomy tract.Atract of 20 F reduees arterial injury compared with a tract of 32 F.

OBJECTIVETo observe the effectiveness and safety of electrothermal acupuncture in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in the cancerous patients of phlegm-stasis interaction in cisplatin-containing chemotherapy.

METHODSSixty cases of phlegm-stasis interaction in cisplatin-containing chemotherapy were randomized into a trial group and a control group, 30 cases in each one. In the control group, the intravenous drip of granisetron hydrochloride injection was adopted, 3 mg before and after cisplatin-containing chemotherapy 30 min, continuously for 3 days. 43 to 45℃ electrothermal acupuncture at zusanli(ST 36) for 30 min was used on the basis of the treatment as the control group in the trial group,once a day for 3 days. CINV, anti-nausea effects, Karnofsky score, the syndrome score of phlegm-stasis interaction, and relevant indices of safety were observed on the 1st and 7th days of cisplatin-containing chemotherapy separately.

RESULTS1.Regarding CINV and anti-nausea effect, CINV did not occur before chemotherapy in the patients of the two groups. On the 1st and 7th days of chemotherapy, CINV in the trial group were milder than those in the control group (both<0.05).The anti-nausea effects in the trail group were better than those of the control group.2.Regarding Karnofsky score and the syndrome score of phlegm-stasis interaction, the improvements on the 7th days of chemotherapy in the trial group were better than those in the control group, indicating the significant differences (both<0.05). 3.Regarding the safety indies, there was no adverse reaction during the treatment in the two groups.

CONCLUSIONSThe electrothermal acupuncture effectively relieves CINV, and improves self-care dbility and the symptoms of phlegm-stasis interaction.
