Chinese Journal of Radiology 2001;0(05):-
Objective To analyze the complications associated with pelvic intraarterial therapy in patients with recurrent and advanced gynecologic cancer and to discuss the causes, the prevention and management measures of the complications in details. Methods One hundred and thirty procedures of pelvic intraarterial therapy were performed in 78 patients with pathologically confirmed recurrent and advanced gynecologic cancer, with one to six procedures per case. The Seldinger technique was used in all patients. The catheter was introduced via femoral artery on one side (mostly on the right side), and the combined antineoplastic agents were infused into contralateral internal iliac artery and(or) ipsilateral branches supplying the involved area. Common iliac arteries and inferior mesenteric arteries were also used in some cases. Results Six patients (7.69%) developed severe skin and subcutaneous necrosis (erosion or ulceration) on the buttock and vulvae. Five of them recovered from the injuries after heteropathy in less than 2 months. One patient received surgical debridement 4 months after the pelvic chemotherapy, whose wound healed one month later. Conclusion The causes of the severe complications of pelvic intraarterial therapy were as follows: the infusing chemotherapeutic agent was too large in dosage and too dense in concentration; the infusing time was too short; the internal iliac artery gave off a lot of abnormal skin branches; the catheter was placed too distal in small branches; the embolic pieces was too small; and the development of collateral arteries was poor especially in pretreated patients with pelvic surgery and(or) radiotherapy, etc. Heteropathy should be given in no time when the severe complications were encountered, and surgical debridement and(or) skin grafting was a need in some cases. So the interventional performers should be familiar with pelvic arteriograms to select the proper location of catheter, administer the suitable dosage of therapeutic agents dilutedly and slowly, and use large emboli, such as larger Gelfoam particles or strips.

Objective To evaluate the condition of living renal donors with 3-dimensional volume rendering computed tomography (3D-CT) in preoperation. Methods 10 consecutive cases received hand-assisted transperitoneal laparoscopic living donor nephrectomy (HLDN) from December 2001 to July. Total patients underwent 3-dimensional volume rendering computed tomography before operation for assessing the condition of the anatomical location, number, anomalies and spatial interrelationships of the renal arteries and veins. These 3D-CT were directly compare with intraoperative surgical findings at laparoscopy and the harvested kidney ex vivo to value the sensitivity and accuracy of 3D-CT. Results The CT digital data of 10 cases were reconstructed to 3D-CT with volume rendering technique, and HLDN were performed successfully in all the cases. The 3D-CT accurately identifies renal vascular anatomy. Conclusions Not only the 3D-CT accurately identifies renal vascular anatomy but also tridimensional images reconstructed by the enhanced CT digital data of arterial phase, venous phase and renal parenchymal phase are viewed by surgeon in any position. It is a manner that may facilitate renal hilar dissection during laparoscopic donor nephrectomy. The 3D-CT should be a routine examination for living donor in preoperation

Objective To study the chimerism formation in kidney transplantation recipient receiving peripheral blood stem cells (PBSCs) of the donor after the patient received preoperative total lymphoid irradiation (TLI). Methods 5 patients of living donor kidney transplantation were involved in present study. The mean age of donors was 40 and that of recipients was 27. There was one patients with 4 HLA antigen mismatches out of 6 HLA-A, B, DR antigens, two patients with 3 HLA-mismatches, and two patients with 1 HLA-mismatch. The patients received TLI in doses 90cGy/d from day -5 to day -1. The immunosuppression protocol for these patients during operation and afteroperation was similar to that for other cases, but the dosage was slightly reduced. Donor PBSCs were harvested twice via leukapheresis after the administration of human recombinant granulocyte colony stimulating factor (G-CSF). PBSCs were infused intravenously to the recipients on postoperative day 4 and 7. Chimerism of peripheral blood cell in recipients was detected by PCR-SSP assays. The grafted kidney function, acute rejection frequency and GVHD episodes were also observed. Results After 5 days of G-CSF based mobilizing regimen, the average number of PBSCs harvested from donors was 34?10~6. At 1 month post-transplantation, donor type HLA-DR gene was detected in all the recipients. At 2 and 3 months post-transplantation, chimerism was not detectable in the recipient with 4 HLA antigens (including 2 HLA-DR) mismatched donor kidney and in the recipient with 3 HLA (including 2 HLA-DR and 1 HLA-B) mismatched donor, respectively. In the other 3 recipients, chimerism was still positive 3 months post-transplantation. There were no symptoms of GVHD or infections after infusion of PBSCs. Transplanted kidneys functioned normally and no rejection episodes were observed till the end of the study. The immunosuppressant dosage was lower for these 5 cases than those after conventional cadavar renal transplantation. Conclusions Non-myeloablative TLI conditioning regimen is a safe and effective method which can promote the engraftment of donor PBSCs and induce hemopoietic chimerism. Chimerism can alleviate rejection of the transplanted kidney and reduce the immunosuppressant dosage. Collection and infusion of PBSCs are simple, convenient, effective, and inexpensive, and it is an optimal source of hemopoietic stem cells.

Objective To investigate the safety and effectiveness of the application of an immunosuppressing primed total lymphoid irradiation (TLI) of the recipient in kidney transplantation of living donor kidney graft. Methods 5 recipients, 3 males and 2 females with the average age of 27, underwent the primed regimen of TLI. As to 6 HLA-A, B, DR antigens of donors and recipients, 4 HLA antigen mismatches were found in one case, 3 mismatches in two cases, and 1 mismatch in two cases. The donor grafts were procured by the technique of hand-assisted transperitoneal laparoscopic living donor nephrectomy (HLDN). The primed regimen of TLI was carried out 5 days before the operation in a dosage 90 cGy/d. The intra- and postoperative immunosuppressant protocols for these cases were similar to that for the other cases, but the doses were reduced slightly. WBC, total T cell, CD4~+ and CD8~+ T cell subsets and Th1/Th2 immune deviation were examined in recipients periodically. The function of the grafted kidney, acute rejection frequency, and side effects of TLI were also observed. Results In the recipients undergone TLI, the total WBC and T cell, CD4~+ and CD8~+ subsets were reduced to a base value at 1-2 weeks post-transplantation and did not restore to the pre-transplantation levels until the investigation was ended. A particular phenomenon showing that in TLI based regimen T cells were shifted from Th1 to Th2 cells was observed. No side effects of TLI, such as infection, were found during the observation. Transplanted kidneys functioned normally and no rejection episodes were observed up to the end of the study. The immunosuppressant doses for those 5 cases were lower than that of conventional protocol. Conclusions TLI based non-myeloablative primed regimen is a safe and effective method for immunosuppression without serious side effects, and it can markedly alleviate kidney transplant rejection and reduce the dosage of immunosuppressive drugs.

Background and purpose:Now 3-dimensional conformal radiotherapy(3DCRT)and intensitymodulated radiotherapy(IMRT)are widely used in the treatment of head and neck tumor.For the parotid,this target area is located on the side of the head and the tumor has a concave shape.What kind of radiation method can be used more eriectively to achieve dose uniformity and protection organs at risk is the topic of much discussion.The postoperative irradiation of parotid tumor is varied in the techniques used.In this study,3-dimensional conformal radiotherapy (3DCRT),intensity-modulated radiotherapy(IMRT)and simplified forward planned multi-segment radiotherapy (MSRT)were compared to conventional planning techniques in order to investigate the potential advantages of these new treatments.Methods:The conventional planning included the large opposed lateral fields with 2 or 3 weight ratio at the target lateral(2F-2D)and the unilateral field with mixture of 6 MV photon and electron beams(X+E).The 3D techniques included 3DCRT,MSRT and IMRT.Their dose distributions were calculated and compared for 8 patients treated in our center.Different beam arrangements were used for 3D techniques.In each case.the dose of PTV was prescribed to 60 Gy.All plans were compared using dose-volume histogram data.The conformity index(CI)and heterogeneity index(HI)of dose were used to evaluate the dose coverage of the target volume.Dose sparing of brain stem.spinal cord and the contra lateral parotid was also compared.To compare IMRT and MS RT,the timing ofplanning and radiation delivery was recorded.Results:Compared to conventional planning,the 3DCRT,MSRT and IMRT plans produced adequate target coverage,and the CI showed 3DCRT plans(0.78)produced poorer target coverage than MSRT(0.81)and IMRT(0.85).MRST and IMRT plans showed a significant reduction in maximum dose to the spinal cord,brainstem and the contra lateral parotid,compared to the conventional plans,while the 3DCRT plan did not show significant sparing of these structures.MSRT and IMRT plans produced better dose coverage among all the techniques.The efficacy of beam delivery comparing between two modulated planning showed MSRT was better.Conclusion:For postoperative irradiation of parotid cancer,3D planning techniques generated better target dose-coverage,without compromising the dose-sparing advantages of important structures.A satisfactory dose distribution can be obtained using MSRT and such a simple technique may be suitable for replacing IMRT.

OBJECTIVE: To investigate the effects of Erxian Decoction (EXD), a traditional Chinese compound herbal medicine and its separate prescriptions such as Wenshen Yijing Recipe (WSYJR, a recipe for warming kidney and replenishing essence), Ziyin Xiehuo Recipe (ZYXHR, a recipe for nourishing yin and dispersing fire) and Tiaoli Chongren Recipe (TLCRR, a recipe for regulating thoroughfare and conception vessels) and some extracts from EXD on the levels of LH and FSH in the primary cultured anterior pituitary cells from female rats. METHODS: EXD, its separate prescriptions and traditional Chinese herbal extracts from EXD were added directly to the incubators. The levels of LH and FSH were tested by radioimmunoassay. RESULTS: The levels of LH and FSH in the supernatant of anterior pituitary cells treated by EXD or its separate prescriptions including ZYXHR and TLCRR were increased significantly as compared with those in the blank control. There was a tendency for stimulating the secretions of LH and FSH in the WSYJR-treated group too. Dimethyl sulfoxide as the solvent of icariin and curculigoside could interfere with the results. CONCLUSION: EXD and its separate prescriptions such as ZYXHR and TLCRR can increase the levels of LH and FSH significantly.
