Purpose To investigate the significance of arterial phase display of right ovarian vein (ROV) for patients with pelvic congestion syndrome (PCS) through multi-slice CT angiography (MSCTA) Materials and Methods Forty-three patients with PCS confirmed clinically who underwent MSCTA were involved in the study. Revascularization was realized via add vessel volume rendering technique and maximum intensity projection (MIP) and the relationships among ROV early development, location of converging vascular, development of LOV and pelvic draining veins were analyzed. Results Out of 43 cases of ROV early development during arterial phase, 21 cases (48.8%) took ROV as draining vein of PCS, among which 17 cases (81.0%) converged into the inferior cava vena. In 19 cases (44.2%), ROV took part in the formation of PCS, all originating from the main right renal vein. Three cases (7.0%) were renal vein-derived PCS, among which two ROV originated from the main right renal vein and one from the branch of the right renal vein. Conclusion According to the imaging features of bilateral ovarian veins and pelvic veins, ROV, as draining veins, is associated with the formation of PCS.

Objective To investigate the way to accurately delineate gross tumor volume (GTV) of high grade gliomas(HGG) for intensity modulated radiation therapy (IMRT) by using computed tomography (CT) and magnetic resonance imaging (MRI) image fusion technique. Methods CT and MRI images were fused from 19 patients. The GTV of each patient were independently delineated by one chief doctor and one resident doctor on CT and MRI image. The GTV contoured on CT (GTVCT), MRI (GTVMRI) were measured, and composite volumes (GTVCT+MRI) were the sum of CT-defined GTV and MRI-defined GTV. The differences of these volumes were compared. Results Whether chief or resident doctors delineated, all were GTVMRI ＞GTVCT(P ＜0.050). The percentages of GTVMRI on GTVCT+MRI were (98.57±7.00)% by chief doctors, and (97.84±10.00)% by resident doctors. Compared the difference between GTVCT and GTVMRI in postoperative patients and preoperative patients, P =0.046, and the difference between chief doctors and resident doctors was statistically significant for GTV defined by CT (P =0.020), but not by MRI and composite image (P ＞0.050).Conclusion The GTV of HGG patients must be delineated on both CT image and MRI image, including using CT and MRI image fusion. But the composite volumes(GTVCT+MRI) should be the sum of CT-defined GTV and MRI-defined GTV. Especially for the postoperative patients,delineating GTV should be taken more attention. And the GTV should be delineated by doctors with full experiences.

Objective:To study on the effects of gastrointestinal function and portal vein hemodynamics applicated with abdominal hot compressing with evodiae fructus and crude salt after hepatectomy.Methods:A total of 60 patients who underwent hepatectomy were randomly divided into 2 groups by random number table method, with 30 in each group. The control group was treated with conventional basic western medicine, while the treatment group was treated with medicinal evodiae fructus and crude salt hot compress on abdomen on the basis of the control group. The portal vein diameter (PVD), portal venous flow velocity (PVV), recovery time of main clinical indexes, clinical symptom scores and liver function indexes were dynamically monitored at different observation time points.Results:The scores of abdominal distension, nausea and vomiting in the treatment group were significantly lower than those in the control group 3 days after treatment ( t values were -3.489 and -2.740, respectively, all Ps<0.05). The recovery time of bowel sounds, first exhaust time and first defecation time in the treatment group were significantly earlier than those in the control group ( t values were -3.622, -4.297 and -4.151, respectively, all Ps<0.01). With the extension of treatment time, ALT in 2 groups showed a gradual downward trend ( P<0.05 or P<0.01), DBIL in control group was significantly higher at 3 days after treatment than before ( t=-2.157, P=0.039), and TBIL was significantly lower at 7 days after treatment than before ( t=2.175, P=0.038). The PVD ( t values were 3.528, 2.160) and PVV ( t values were 11.096, 4.264) of the treatment group were significantly higher than those of the control group 3 and 5 days after treatment ( P<0.01 or P<0.05). Conclusion:Early application of abdominal hot compressing with evodiae fructus and crude salt hot compress on abdomen after hepatectomy can improve the portal vein blood circulation and promote the rehabilitation of gastrointestinal function in patients with hepatectomy.

Objective:To investigate the relationship between triglyceride glucos (TyG), C-reaction protein/albumin (CRP/Alb), 25-hydroxy vitamin D[25(OH)D] and the prognosis of patients with continous ambulatory peritoneal dialysis (CAPD).Methods:A total of 220 CAPD patients in the Affiliated Hospital of Jining Medical University from January 2017 to March 2020 were prospectively selected and divided into death group and survival group according to the 6-month prognosis. The peritoneal urea clearance index (Kt/V urea), TyG, CRP/Alb, 25(OH)D were compared between the two groups. Logistic regression was used to analyze the prognostic factors of CAPD patients. The predictive value of TyG, CRP/Alb and 25(OH)D on the prognosis of CAPD patients was analyzed by receiver operating characteristic (ROC) curve. Results:After 3 months and 6 months of dialysis, the peritoneal Kt/V urea in the death group [(1.21±0.18)ml/(s·1.73 m 2), (1.02±0.14)ml/(s·1.73 m 2)] was significantly lower than that in the survival group [(1.57±0.40)ml/(s·1.73 m 2), (1.49±0.42)ml/(s·1.73 m 2)] (all P<0.05). After 3 months and 6 months of dialysis, the TyG [(8.79±0.86), (9.24±1.03)] and CRP/Alb [(4.98±0.94)×10 -4, (5.14±1.39)×10 -4] in the death group were higher than those in the survival group [(8.03±0.60), (7.26±0.93), (3.57±1.19)×10 -4, (3.07±0.88)×10 -4], while the 25(OH)D [(19.14±2.29)ng/ml, (17.79±3.17)ng/ml] was lower than that of survival group [(22.67±3.03)ng/ml, (24.31±2.51)ng/ml] (all P<0.05). TyG and CRP/Alb at 3 months and 6 months of dialysis were negatively correlated with Kt/V urea, while the 25(OH)D was positively correlated with Kt/V urea (all P<0.05). Logistic regression analysis showed that Kt/Vurea, TyG, CRP/Alb and 25(OH)D were associated with prognosis in the two groups after 3 and 6 months of dialysis (all P<0.05). The AUC of TyG, CRP/Alb and 25(OH)D at 6 months of dialysis combined to predict the prognosis of CAPD patients was the highest, which was 0.911. Conclusions:TyG, CRP/Alb and 25(OH)D are associated with all-cause mortality in CAPD patients. High TyG and CRP/Alb and low 25(OH)D suggest a higher risk of all-cause mortality. Combined detection of all indicators can effectively predict the prognosis of CAPD, which is convenient for early clinical intervention.
