OBJECTIVETo observe the effects of electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) com- bined with granisetron on nausea and vomiting as well as serum levels of 5-hydroxy tryptamine (5-HT) and dopamine (DA) in chemotherapy patients.

METHODSSeventy-two chemotherapy patients who met the inclusive criteria were randomly divided into an observation group (38 cases) and a control group (34 cases). The patients in the observation group were treated with electroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron injection; the patients in the control group were treated with electroacupuncture at sham-point 1 and sham- point 2, and the rest treatment was identical to the observation group. After 3-day treatment, the clinical indices including times of vomiting and severity of nausea, etc. were observed in the two groups.

RESULTS(1) At the acute stage within 24 h, the times of vomiting in the two groups were not significantly different (P>0.05); at the delay stage, the severity of nausea was significantly higher in the control group (P<0.05). (2) As for the comprehensive efficacy and rate of complete control, there was no obvious difference between the two groups at the acute stage (P>0.05); while in the delay stage, the rate of complete control in the observation group was superior to that in the control group (P<0.01). (3) Compared before and after the treatment, serum levels of 5-HT and DA were evidently reduced in the observation group (both P<0.05), while those in the control group were not significantly changed after treatment (both P>0.05).

CONCLUSIONElectroacupuncture at Neiguan (PC 6) and Jianshi (PC 5) combined with granisetron could obviously relieve the nausea in chemotherapy patients at the delay stage. The effect mechanism is possibly related to reducing the content of 5-HIT nndl nA

Objective To investigate the depressing effect of antigene peptide nucleic acid (AGPNA)on the k-ras gene expression of human pancreatic cancer Patu8988 cells, the inducing apoptosis effect on Patu8988 cells, and the biodistribution characteristics in nude mice bearing xenografts using 188Re-k-ras-AGPNA.Methods The expression level of k-ras mRNA and the expression ratio of k-ras protein in Patu8988 cells transfected with AGPNA was measured by RT-PCR and flow cytometry ,respectively. The degree of cellular apoptosis 3 to 5 d after treating Patu8988 cells with 188Re-k-ras-AGPNA or 188ReO4- was determined by flow cytometry. For biodistribution study, 58 nude mice bearing Patu8988 cell xenografts were divided into two groups: intratumoral injection of 188Re-k-ras-AGPNA (Group A) and 188ReO4- (Group B). At different time points, the mice were sacrificed and organs of interest were excised, weighted and counted by a gamma counter. The organ uptake was calculated as a % ID/g and the absorbed doses of organs were calculated. One-way analysis of variance was used. Results After transfected with 1 nmol/ml AGPNA, the k-ras mRNA gray scale ratio and the expression ratio of k-ras protein were 1.00 ± 0.39 and (15.05 ± 5.07)%, respectively. They were significantly lower than those of the control group with 1.86 ± 0.07 and (24. 38 ± 5.40) % (F = 2. 545, 5. 327, P<0. 05). At 4 and 5 d after treatment in Group A, float cells' apoptosis ratios were (26.30 ± 7.45) % and (27.90 ± 10. 38) %, respectively. Tumors were the major distribution site in Group A with uptake of (37.47 ±21.31), (35.96 ±7.80) and (15.46 ±4.93) %lD/g at 1 h, 1 d and 7 d after intra-tumor injection, respectively. The absorbed dose of tumor was 15 569 mGy/MBq. Condusions Transfection with k-ras-AGPNA on Patu8988 cells may inhibit k-ras expression at mRNA and protein expression level, and 188Re-k-ras-AGPNA can induce apoptosis of Patu8988 cells.Tumor is the major distribution site in nude mice bearing human pancreatic cancer xenografts after intratumoral injection of 188Re-k-ras-AGPNA.
