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 explore the effects of vacuum sealing combined with NovaBay on improving diabetic foot wound healing, and to offer new insights and methods for treating chronic aporetic wounds. Methods Totally 130 patients with diabetic foot ulcer admitted in the Second Affiliated Hospital of Zhejiang Chinese Medical University between November 2015 and November 2016 were randomly and equally divided into two groups. Patients in the treatment group received 5 ml NovaBay for twice a day on the basis of vacuum sealing drainage (VSD), and received drainage 5 min after treatment with NovaBay, while patients in the control group received vacuum sealing drainage with 5 ml 0.9% sodium chloride solution for twice a day, and received drainage 5 min after treatment of sodium chloride solution. The intervention time of the patients in both groups were 12 days, with NovaBay and ducts replaced every 3 days. The patients in the two groups were evaluated with Pressure Ulcer Scale for Healing (PUSH) and the coverage rate of granulation tissue was calculated 0, 6, and 12 days after the intervention. And the positive rate of bacteria was tested at the end of the intervention. Results The PUSH scores of the patients in the two groups decreased as time went by, indicating that the wound healing was effective (P<0.001). The coverage rate of granulation tissue rose with time, and that of the patients in the treatment group rose more obviously (P<0.001). 12 days after the intervention, the patients in the treatment group (4.62%) showed a lower positive rate of bacteria (P<0.001) than the patients in the control group (47.70%). Conclusions Vacuum sealing combined with NovaBay shows remarkable effects in cleaning infection of chronic and aporetic wounds, thus a new and effective way to improve the growth of granulation tissue and wound healing.

Objective:Evaluate the effects of brief mindfulness meditation training on improving negative e-motions,mindfulness attention awareness,and sleep quality in patients after percutaneous coronary intervention(PCI)for coronary heart disease.Methods:Eighty-four patients with coronary heart disease after PCI admitted to the cardiology department were selected.According to the principle of simple randomization,they were divided into an intervention group of 42 cases and a control group of 42 cases.The Self Rating Anxiety Scale/Self Rating De-pression Scale,Mindfulness Attention Awareness Scale,and Pittsburgh Sleep Quality Index Scale were used as eval-uation indicators before and after intervention.Results:The difference in total scores of anxiety,depression,and mindfulness attention awareness before and after intervention in the intervention group was higher than that in the control group(P＜0.05).The difference in total sleep score,sleep quality,time to fall asleep,sleep duration,use of hypnotic drugs,daytime dysfunction,and total sleep score before and after intervention was higher than that of the control group(P＜0.05).Conclusion:It suggests that brief mindfulness meditation training could alleviate negative emotions in patients with coronary heart disease after PCI,improve mindfulness awareness,and improve sleep quali-ty.

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.
