Objective To investigate the relevant risk factors for cardiovascular autonomic neuropathy (CAN) in diabetic patients. Methods 712 cases of diabetic patients were divided into two groups according to their cardiovascular autonomic function test: one group with CAN (n=160) , and the other without CAN (n=552). Duration of diabetes, profession, body mass index (BMI), blood glucose, lipid profile, glycosylated hemoglobin (HbA1C) and urinary albumin excretion rate (UAER) were measured. Results Duration of diabetes, the levels of fasting plasm glucose (FBG), triglyceride (TG), VLDL-C, APOB, UAER were significantly higher in CAN group than in non-CAN group (P

Objective To summarize the characteristics of blunt renal injury in children and re-port experiences in its diagnosis and treatment. Methods A comparison was done on medical data of 30 children and 36 adults with blunt renal injury. The renal injuries were classified according to the organ inju-ry scaling committee of the American Association for the Surgery of Trauma. Results The rate of severe renal injury in the children group was 50%, significantly higher than 31% in the adult group(P<0.05).Surgical exploration rate in the children group was 40%, lower than 73% in the adult group(P<0.05).In the meantime, the kidney conservation rate of 93% in children group was higher than 64% in adult group(P<0.01). Conclusions The kidney of children is susceptible to severe injury but has sound serf-repairing capability. Therefore, surgical interventions and nephrectomy should be considered cautiously.

PurposeTo investigate the formation of neovascularization using dynamic contrast-enhanced MRI (DCE-MRI) in C6 glioma margin in rats, and to explore its utility.Materials and MethodsC6 glioma model was created in 24 SD rats. Routine and DCE-MRI was performed 4 days, 8 days, 12 days, 16 days, 20 days and 24 days after transplantation. Pathology and immunohistochemistry exams were also obtained to evaluate marginal tumor cells and neovascularization.ResultsNeovascularization was observed in C6 glioma margin within (257.658±53.663)μm range. Vessel co-option index difference was statistically significant (P<0.01). Tumor cells surrounding the co-opted vessels were strongly positive on proliferating cell nuclear antigen and matrix metallopeptidase 2 staining. Vessel co-option regression and transformation were observed on day 16 on Tenascin-C andα smooth muscle actin staining. For DCE-MRI analysis, Ktrans and Kep were higher on day 12 and 16 (P<0.05). There was significant negative correlation between co-option index and Ktrans (r=-0.9243 and-0.8347,P<0.05). Vp showed no statistically significant difference at all time points (P>0.05).Conclusion The neovascularization in tumor margin demonstrates vessel co-option. DCE-MRI parameters Ktrans and Kep are negatively correlated with co-option index, indicating that Ktrans and Kep could be a well-defined imaging-based biomarker for glioma neovascularization.

Objective To evaluate the safety and efficacy of brachytherapy with 125I seed strand in treating implanted main portal vein tumor thrombus (MPVTT) in experimental rabbits.Methods VX2 tumor cell line was implanted in the main portal vein (MPV) of 32 New Zealand white rabbits to establish MPVTT models.The rabbits were randomly divided into the treatment group (group T,n=16) and the control group (group C,n=16).125I seed strand was implanted in the MPVTT of the rabbits of group T,while blank seed strand was implanted in the MPVTT of the rabbits of group C.After the implantation,the changes in general condition,body weight and laboratory testing results were recorded.Two weeks after the treatment,every 8 rabbits from each group were sacrificed,and the specimens were collected and sent for pathological examination.The remaining rabbits were fed till they died,and then autopsy was conducted.Multi-slice spiral CT manifestations,histopathological findings,Ki-67 labeling index and apoptosis index were used to assess the curative effect,and the results were compared between the two groups.Results At each observation time point after brachytherapy,the weight loss of the experimental rabbits was more obvious in group C than in group T.No statistically significant differences in liver functions and white blood cell count existed between the two groups (P＞0.05).The mean MPVTT volume of group T and group C were (565.40±220.90) mm3 and (2 269.90±437.00) mm3 respectively (P＜0.001);the Ki-67 labeling indexes were (4.14±1.84)％ and (33.82± 6.07)％ respectively (P=0.001);the median survival days were (39.50±2.37) d and (27.38±1.22) d respectively (P=0.001).Conclusion For the treatment of implanted MPVTT in experimental rabbits,brachytherapy with 125I seed strand is safe and effective.

Objective To observe the effect of transcatheter arterial embolization(TAE)with Glubran-2 glue for treating hemorrhage after percutaneous transhepatic cholangial drainage(PTCD).Methods Data of 17 patients with hemorrhage after PTCD who underwent TAE with Glubran-2 glue were retrospectively analyzed.The technical success rate,clinical success rate and complications were observed.The red blood cell(RBC)and hemoglobin(Hb)on the day of TAE and the next day of TAE were compared,also the glutamic-pyruvic transaminase(GPT)level before TAE,on the next day of TAE,on the second and the fourth day after TAE,respectively.Results The offending vessel of bleeding was successfully embolized in all 17 cases,both technical success rate of TAE and clinical success rate of hemostasis were 100%.There was no serious complication such as liver abscess,septicemia nor pulmonary embolism.No significant difference of RBC nor Hb was found between the day of TAE and the next day of TAE(both P＞0.05).GPT before TAE was lower than the next day of TAE and the second day after TAE(P＜0.05),while no significant difference of GPT was found before TAE and 4 days after TAE(P＞0.05).Conclusion TAE with Glubran-2 glue for treating hemorrhage after PTCD was safe and effective.

Objective To discuss the application of gelatin sponge-hemocoagulase plugging agent in patients with pulmonary puncture bleeding.Methods The clinical data of 43 patients with hemorrhage caused by DSA-guided lung puncture biopsy,who received gelatin sponge-hemocoagulase plugging agent treatment at the Jining Municipal First People's Hospital of China between September 2021 and May 2023,were collected,and the hemostatic effect of gelatin sponge-hemocoagulase plugging agent was analyzed.Results Successful lung puncture needle biopsy was achieved in all the 43 patients.The puncture needle channel occlusion was accomplished by using gelatin sponge-hemocoagulase plugging agent.Five minutes after occlusion treatment,in one patient,whose moderate hemoptysis with moderate bleeding shadow before puncture needle biopsy changed to bloody sputum,the intrapulmonary bleeding shadow displayed on image became slightly enlarged when compared the size five minutes ago,while in all the remaining patients successful hemostasis was achieved,the hemoptysis disappeared and the pulmonary hemorrhage shadow was similar to that five minutes ago.No occlusion-related complications occurred in all patients.Conclusion For the treatment of pulmonary hemorrhage caused by DSA-guided lung puncture biopsy,gelatin sponge-hemocoagulase plugging agent is clinically safe and effective.
