Objective:To study the impact on dose accuracy for the treatment planning by manually assigning accurate electron density for CT image-based tumor tissues and organs at risk.Methods:Twenty cases of retrospective postoperative cervical cancer radiotherapy plans were selected. The body electron density of the corresponding organs was derived from the ICRU 46 report and assigned in the treatment planning system (Monaco5.11, Sweden), including the bladder, rectum, intestine, kidney, spinal cord, femoral head, and ilium. The original plans were double-arc volumetric modulated arc therapy plan (360° VMAT), using Monte Carlo algorithm, the calculation grid was 0.3 cm × 0.3 cm × 0.3 cm, and the minimum subfield width was 0.6 cm. Keep the original plan fluence unchanged and recalculate the dose to generate a new plan. The two-dimensional dose distribution and dose-volume histogram (DVH) were used to compare the differences between the two plans. The difference was compared between the two group plans by using the dosimetry parameters and DVH two dimension curve.Results:For the planning of assigning bulk electron density (Plan RED), the deviation of the patient′s target dose parameters and the original plan (Plan ref) was <2%, and the average deviation of all target regions D2, D98, Dmean was < 0.7%, only 2 of the 180 data were between 2% and 3%. The average deviation of V20, V30, D1 cm 3, Dmean of the bladder, rectum, and small intestine, the original Plan ref was less than 0.6%, and 4 out of 240 data had values > 2%. Plan RED′s average hop count was 0.9% higher than Plan ref, and the total number of subfields remains unchanged. The planned dose generated by manually assigning the electron density in Plan RED was higher than that in Plan ref, but met the clinical requirements. The two-dimensional curves of the DVH diagram for targets and OARs almost completely overlapped, and there was no obvious difference in the dose distribution diagram of the same cross section. The statistical result of all parameters showed that the difference in planned dose parameters between the two groups was not statistically significant( P>0.05). Conclusions:The overall deviation of dose accuracy between Plan RED and Plan ref is <2%, which meets the clinical requirements and provides a reference for realizing MRI-only treatment planning.

OBJECTIVETo investigate the clinical effect of bridging fixation with locking plate for the Seinsheimer type V subtrochanteric femoral fracture.

METHODSFrom March 2009 to September 2014,18 cases of Seinsheimer type V subtrochanteric femoral fracture were treated by open reduction and bridging fixation with locking plate through proximal and distal approach including 16 males and 2 females with an average age of 41 years old ranging from 22 to 67 years old. Among them, 12 cases caused by traffic accident, 5 cases by falling, 1 case by heavy aboving. All cases were fresh and closed fractures. Time between injury and operation was from 4 to 9 days with an average of 6.2 days. Of them, 11 cases were fixed with reverse LISS and the other 7 cases were fixed with anatomical locking plates of proximal femur.

RESULTSThe mean time of operation was 110 min (ranged from 90 to 155 min). The mean blood loss during operation was 425 ml (ranged from 350 to 650 ml) and 16 cases got blood transfusion which was meanly 300 ml. The mean hospital time was 14 days (ranged from 12 to 18 days). The mean duration of followed up was 11.8 months (ranged from 8 to 22 months). The mean time of bone union was 6.6 months (ranged from 5 to 8 months). There was not any complication such as infection, implant failure, hip varus, external rotation deformity of low limb or fat embolism. The Sanders hip scores were 53.22 ± 6.48, the result was excellent in 12 cases and good in 6 cases at the last follow-up.

CONCLUSIONUnder the principle of biological osteosynthesis, treatment of Seinsheimer type V subtrochanteric femoral fracture with bridging locking plate fixation has such advantages as high mechanism, less interference of blood supply, stable fixation and little complication. It is a safe and idea way for the treatment of the Seinsheimer type V subtrochanteric femoral fracture.

OBJECTIVETo evaluate its mechanism of inducing the maternal-fetal immune tolerance by studying the effects of Shoutai pills on the expression of Th1/Th2 cytokine and pregnancy in maternal-fetal interface of mice with recurrent spontaneous abortion (RSA).

METHODThe normal pregnancy and RSA model were respectively induced with CBA/J x BALB/c and CBA/J x DBA/2. The mice with RSA were randomly divided into model group and low, middle and high dose groups of Shoutai pills. The mice were killed in 14 days after administration and embryo resorption rate was counted and their decidual and placental tissues were co-cultured to detect the expressions of IL-4, IL-10, IFN-gamma and TNF-alpha with ELISA.

RESULTThe embryo resorption rate of the model group was significantly higher than the normal pregnancy, middle and high dose groups of Shoutai pills could decreased the embryo resorption rate of the mice with RSA (P < 0.05). All the doses in 3 groups of Shoutai pills could decreased the expression of IFN-gamma and TNF-alpha (P < 0. 05) and there was no obvious difference between normal pregnancy group and all groups of Shoutai pills. Middle and high doses of Shoutai pills could increased the expression of IL-4 and IL-10 (P < 0.05) and there was no obvious differences between normal pregnancy and high dose group of Shoutai pills.

CONCLUSIONThe mechanism about Shoutai pills can change Th1 /Th2 cytokine towards Th2 bias, which induced the maternal-fetal immune tolerance.

OBJECTIVETo review the surgical treatment of supracardiac type of total anomalous pulmonary venous connection (TAPVC).

METHODSTwenty-four patients with supracardiac total anomalous pulmonary venous connection underwent surgical correction from July 1995 to June 2004. There were 11 males, 13 females. The patients aged from 40 days to 35 years (mean 4.5 years). Twenty-three patients were under 6 years old. The weight was from 3.8 to 54.0 kg (mean 17.5 kg). Ten patients were through right atrial incision, 8 through double-atrium incision to anastomose the left atria and the common pulmonary veins. Two used large patches separating the portal of the common pulmonary veins and the enlarged atrial septal defects to the left atria. The left atrium and the common pulmonary veins were anastomosed in one case using a large patch separating the portal of the common pulmonary vein and the enlarged atrial septal defect to the left atrium. Three anastomosed the top of the left atria and the common pulmonary veins.

RESULTSOne patient died postoperatively of low cardiac output syndrome. One with cardiac tamponade after operation was cured by reoperation. Six with arrhythia were all cured. One with acute pulmonary edema was cured by reopen of the vertical vein and closed later. The postoperative follow-up period ranged from 3 months to 7 years (mean 2.5 years). One complicated severe supracardiac arrhythia 2 weeks later. One with late pulmonary occlusion was cured by reoperation. There was no long term complication of the others.

CONCLUSIONSThe operative methods of TAPVC depend on the cardiac deformation. Proper surgery timely treatment of the postoperative complications may achieve a satisfactory result. The method of only use patch in the right atrium should select proper repair material. Anastomosing the top of the left atrium and the common pulmonary vein is a good method. It is easy for exposure and operating, meanwhile it has low occurrence of arrhythmias and should be recommended.

OBJECTIVESTo investigate the impacts of laparoscopic bariatric surgery on fasting glucagon-like peptide-1 (GLP-1) and Ghrelin level in patients with type 2 diabetes mellitus (T2DM), and the mechanism in surgical treatment of T2DM.

METHODSFrom March 2010 to August 2011, 44 patients with T2DM underwent laparoscopic bariatric, including laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 14), laparoscopic mini-gastric bypass (LMGB, n = 11), laparoscopic sleeve gastrectomy (LSG, n = 9) and laparoscopic adjustable gastric banding (LAGB, n = 10). The curative effects, changes of metabolism and gastrointestinal hormones were analyzed respectively.

RESULTSWithin 6 months after surgery, the clinical complete remission of T2DM was 11, 8, 6, 3 cases in LRYGB, LMGB, LSG, LAGB group respectively; the clinical partial remission was 3, 3, 2, 4 cases respectively. The inefficacy was 1, 3 patients in LSG and LAGB group respectively. The effects of surgery within 6 months postoperative among 4 groups were different (χ(2) = 8.162, P < 0.05). The levels of body mass index (F = 275.29) and homeostasis model assessment of insulin resistance (F = 40.09) of 4 groups were declined in 6 months postoperatively (P < 0.01). The extents of decrease were no significance among 4 groups. Compared to preoperative level, GLP-1 in LRYGB ((116 ± 33) vs. (66 ± 20) ng/L and LMGB group ((103 ± 22) vs. (65 ± 16) ng/L) was higher in the first month after surgery (F = 21.76 and 139.21, P < 0.05). The changes in LSG and LAGB group were no significance (P > 0.05). The level of Ghrelin in LRYGB, LMGB, LSG group at the first week after surgery were (208 ± 79), (275 ± 102) and (258 ± 91) ng/L respectively, and they were lower than preoperative (there were (398 ± 114), (439 ± 96) and (446 ± 105) ng/L, F = 55.08, 49.96 and 46.47, all P < 0.01). But the level of Ghrelin in LRYGB and LMGB groups rebounded in the first postoperative month. The postoperative level of Ghrelin was higher in LAGB group (F = 29.24, P = 0.001).

CONCLUSIONSThere are difference efficacies and impacts on gastrointestinal hormones among different modes of bariatric surgery. The change of gastrointestinal hormones is plausible mechanism of T2DM remission after surgery.

OBJECTIVETo observe the effect of sirolimus-based immunosuppression administered on heart transplant recipients with chronic renal dysfunction.

METHODSFrom June 2004 to December 2008, standard calcineurin inhibitors (CNI)-based immunosuppressive regimen was changed to reduced-dose CNI plus sirolimus due to CNI-related chronic renal dysfunction in 20 out of 138 cardiac transplant recipients at Fuwai Hospital. The standard immunosuppressive regimen included steroid, CNI (cyclosporine or tacrolimus), and mycophenolate mofetil or azathioprine. Sirolimus was started at 0.75 - 1.50 mg/d with titration to achieve levels of 5 - 15 µg/L, and CNI dose was reduced gradually to 1/2-2/3 of the baseline level. Patients were followed for changes in renal function, lipid level and clinical side effects related to immunosuppressive therapy. Endomyocardial biopsy (EMB) was performed routinely at 3 weeks, 3, 6 and 12 months after transplantation. EMB was also performed at 3 months after regimen change within 1 year post-transplantation or when rejections were suspected in patients beyond 1 year post-transplantation. Echocardiography was performed for monitoring purpose.

RESULTSThe mean follow-up after regimen change was (7.9 ± 6.3) months. Final sirolimus dose was (0.89 ± 0.22) mg/d and blood drug level was (7.6 ± 3.8)µg/L. Cyclosporine dose was reduced from (191.7 ± 60.0) mg/d to (123.6 ± 34.8) mg/d, with blood drug concentration reduced from (175.5 ± 58.0) µg/L to (111.9 ± 56.0) µg/L in 18 patients (P < 0.01). Tacrolimus average dose was reduced from 4.25 mg/d to 3.00 mg/d, with blood drug concentration reduced from 13.5 µg/L to 10.5 µg/L in 2 patients. Serum creatinine level fell from (160.4 ± 25.5) µmol/L to (134.4 ± 26.8) µmol/L (P < 0.01) and urea nitrogen fell from (13.8 ± 4.7) µmol/L to (10.4 ± 3.0) µmol/L (P < 0.01) at one month after regimen change. Twenty two EMBs were performed in 11 patients within 1 year post-transplant, there were 4 episodes of acute rejected (ISHLT grade 2). Twenty patients are all alive and cardiac function was normal. The most common side effect was hyperlipidemia, and triglycerides, total cholesterol and low density lipoprotein levels were significantly increased at 1 month post regimen change (P < 0.05 or P < 0.01). Leukocyte, hemoglobin and platelet as well as liver function remained unchanged at 1 month post regimen change (all P > 0.05).

CONCLUSIONOur results show that change from CNI-based immunosuppressive regimen to reduced-dose CNI plus sirolimus is an effective and safe approach for the management of patients with CNI-related chronic renal dysfunction, leading to an improvement in renal function without compromise in anti-rejection efficacy and with tolerable side effects.
