AIM: To compare the impacts of adriamycin(ADM) intermittent and continuous heat infusion on respiration, heart rate and temperature of the rabbit as well as the concentration of ADM in VX-2 tumor for the verification of the safety and effectiveness of intermittent heat infusion through VX-2 transplanted tumor model in rabbit liver.METHODS: VX-2 tumor models were established respectively in the thighs of 30 New Zealand rabbits. All 30 rabbits were randomly allocated into three groups with 10 rabbits each. After catheterizing into femoral artery, which was demonstrated as the supply artery of tumors by digital subtraction angiography(DSA), animals in three groups were infused with 100 mL saline at normal temperature and ADM, 100 mL saline at 60 ℃ and ADM continuously and 100 mL saline at 60 ℃ and ADM intermittently respectively. During infusion, the 43 ℃ to 45 ℃ lasting time in the tumor tissues of the two 60 ℃ groups was measured. After infusion, the respiration(time/minute), heart rate(beats/minute) and temperature(℃ )of the rabbits in each group as well as the concentrations of ADM in tumor tissue were measured immediately.RESULTS: The concentration of ADM was (7. 1 ± 2.2) mg/L in normal temperature infusion group, (17.2 ± 1.6) mg/L in 60 ℃ continuous infusion group and(16.5 ±3.4) in 60 ℃ intermittent infusion group. There were significant differences among three groups( F = 48.95, P = 0. 000), but there was no significant difference between 60 ℃ intermittent infusion group and 60 ℃ continuous infusion group( P > 0. 05). 43℃ to 45 ℃ lasting time was(22.5 ±1.4) minutes in 60 ℃continuous infusion and (24.3±2.4)minutes in 60 ℃intermittent infusion group( F =4.20, P > 0.05) . There were significant differences among three groups in respiration, heart rate and temperature( F = 14. 58, 33.07, 10.00, P < 0.01), but there was no significant difference in the respiration, heart rate and temperature between 60℃ intermittent infusion and normal temperature infusion group ( P > 0. 05).CONCLUSION: Intermittent thermochemotherapy is a more effective and safe interventional thermochemotherapy method compared with continuous heat infusion.

Objective To investigate the clinical characteristics and the optimal time of delivery in pregnant women with severe preeclampsia complicated with ascites. Methods A retrospective study was conducted on 179 severe preeclampsia mothers and their 195 neonates,presented in the First Affiliated Hospital of Wenzhou Medical College from Jan.2003 to Dec.2005,who were divided into two groups:32 complicated with ascites(ascites group)and 147 without(non-ascites group). The general conditions,mode of delivery and complications including eclampsia,hemolysis,elevated serum level of 1iver enzymes,and low platelets(HELLP syndrome),liver failure,renal failure,heart failure,hypoproteinemia,placental abruption,postpartum hemorrhage and puerperal infection,were also analyzed.Clinical data of all infants(38 from ascites group and 157 from non-ascites group)were analyzed.The incidence and mortality rate of small for gestational age(SGA)in both group within the same gestational age group and those between different gestational age groups in the ascites group were compared. Results (1)The average gestations at admission and delivery in the ascites group were earlier than the other[admission:(32.5±2.1)weeks vs(36.1±3.5)weeks;delivery:(34.1±2.3)weeks vs(37.2±1.5)weeks,P<0.053.The rate of systemic antenatal care in the ascites group waslowcr than that of the non-ascites group(25.0%vs 53.7%,P<0.05).More complications werefound in the ascites group than in the non-ascites group(hypoproteinemia:100.0%vs 47.0%;liver and renal failure:31.2%vs 8.2%;HELLP syndrome:9.4%vs 2.0%;postpartum hemorrhage:18.8%vs 2.0%;all P<0.05).(2)The incidence of SGA in the ascites group was all higher than that in the non-ascites group,however,significant differences was only found between the tWO groups at>36 weeks(7/9 vs 30.2%,P<20.05).The perinatal mortalily rates of SGA in the ascites group at<32 weeks and 32~34 weeks were significantly higher than that in the non-aseites group respectively(<32 weeks:69.2%vs 19.2%,P<0.05;32~34 weeks:2/7 vs 0,P<0.05).(3)The highest perinatal mortality rate and the highest incidence of SGA in the ascites group were found in the groups of<232 weeks and>36 weeks,respectively. Conclusions The early onset of ascites and higher rate of complications in severe preeelamptie women implies the adverse maternaI and fetal outcomes.Ascites in severe preeclampsia cases should alert the clinicians.The optimal time for delivery might be at 32~36 weeks of gestations.

Methods A prospective investigation study was conducted on 183 patients of post-operative patients with whole pelvic radiation therapy of cervical cancer or endometrial cancer in Zhejiang Cancer Hospital [IMRT group (n=85) and 3D-CRT group (n=98)] from Oct. 2015 to Oct. 2016. The two groups received same dose (45 Gy in 25 fractions). Comparison of two groups with radiation dosimetry:the score according to the Radiation Therapy Oncology Group (RTOG) acute radiation injury grading standards before and after radiotherapy reaction, the score from functional assessment of cancer therapy scale-cervix (FACT-Cx) scale and expanded prostate cancer index composite for clinical practice (EPIC-CP) scale were also analyzed. Results (1) There were no significant effect with age, culture level, family economic condition and ratio of radiochemotherapy between two groups (all P>0.05). (2) Dosimetric comparison for IMRT vs 3D-CRT:the average dose of planning target volume (PTV) decreased(46.1 ± 0.4) vs(46.4 ± 0.5)Gy, V45 dose percentage increased(95.2 ± 1.0)%vs (93.3 ± 2.0)%, intestinal bag dose of V40 decreased(24.4 ± 6.8)%vs (36.5 ± 15.9)%, rectal V40 dose percentage decreased(73.9 ± 12.3)%vs (85.4 ± 8.4)%, and lower rectal V45 dose percentage(32.8 ± 13.4)%vs (71.5 ± 13.7)%, bladder V40 dose percentage decreased(55.5 ± 13.0)% vs (84.4 ± 13.0)%. Bone marrow V20 lower:(67.9 ± 5.4)% vs (79.5 ± 6.6)%, V10 lower:(82.1 ± 6.0)% vs (86.3 ± 6.6)%; there were significant differences (all P<0.05). There was no significant difference between the dose of V45 in the intestinal pouch and bladder (P>0.05). (3) Acute radiation injury classification for IMRT vs 3D-CRT:big or small intestine:Ⅱ-Ⅲreaction [13%(11/85) vs 24% (24/98); χ2=3.925, P=0.048], there was significant difference. Bladder: Ⅲ reaction [19% (16/85) vs 26% (25/98); χ2=1.171, P=0.279], there was no significant difference. Radiochemotherapy of bone marrow suppression:Ⅲ-Ⅳreaction (14/20), the incidence rate [26%(14/54) vs 31%(20/65);χ2=0.339, P=0.562], the difference was not statistically significant. (4) Quality of life scale by FACT-Cx scale in IMRT vs 3D-CRT:there were no significant difference before radiotherapy (82 ± 16 vs 85 ± 16;t=1.279, P=0.203), while there was significant difference after radiotherapy (76 ± 14 vs 71 ± 18;t=-2.160, P=0.032). EPIC-CP scale score:before radiotherapy they were (16±7 vs 15±6;t=-0.174, P=0.862) ,but after radiotherapy (18±7 vs 22± 7; t=3.158, P=0.002), there was significant difference between them. Before and after radiotherapy, the increased EPIC-CP scale of the IMRT group vs 3D-CRT group were 3 ± 4 and 6 ± 4, the 3D-CRT group was significantly higher, the difference was statistically significant (t=5.500, P=0.000). Conclusion IMRT has shown that there are a significant benefit for the post-operative patients with cervical cancer and endometrial cancer compared to 3D-CRT.
