Objective:To analyze risk factors for the rupture of basilar tip aneurysms (BTA) using morphological parameters assessed on CTA.Methods:The clinical data and CTA imaging characteristics of 62 patients with BTA from March 2016 to November 2020 in Huanhu Hospital of Tianjin were analyzed retrospectively. The patients were divided into un-rupture ( n=44) and rupture ( n=18) groups according to whether the BTA ruptured. The morphological parameters of aneurysms were measured and recorded. The number, shape and orientation of aneurysms were analyzed by χ 2 test between the two groups. The length (H max), height (H p), neck width (N D), aspect ratio (AR), size ratio (SR), angle of aneurysms (AA), flow angle (FA), basilar vessel angle (BVA), the angle between the proximal long axis of bilateral posterior cerebral artery P1 segment (P1-P1 angle), the angle between the proximal long axis of bilateral superior cerebellar arteries and bifurcation angle (the sum of the angle between the basilar artery and the bilateral posterior cerebral arteries) were analyzed by independent-sample t test between the two groups. On the basis of univariate analysis, logistic regression was used to identify the independent risk factors for BTA rupture. ROC curve analysis was further performed. Results:BTA with irregular shape was more likely to break (χ 2=5.412, P<0.05). The H max[(4.18±2.11)mm], N D [(3.06±1.75)mm], P1-P1 angle (148°±18°) in the rupture group were smaller than those in the un-rupture group [(6.38±2.21)mm, (5.20±1.59)mm, 178°±25°], with statistically significant difference ( P<0.05). While AR (1.19±0.13), BVA (82°±11°), and bifurcation angle (212°±18°) in the rupture group were larger than those in the un-rupture group (1.05±0.18, 70°±10°, 181°±27°), with statistically significant difference ( P<0.05). The logistic regression analysis showed that the shape of aneurysms (β=4.878, OR=11.418, P=0.019), BVA (β=0.165, OR=1.177, P=0.043), and P1-P1 angle (β=-0.223, OR=1.080, P=0.029) were independent risk factors for BTA rupture. The ROC curve analysis showed that the cut-off value of BVA and P1-P1 angle to predict the BTA rupture were 76.7° and 158.5°, and area under curve (AUC) were 0.79 and 0.86, respectively. The AUC of combined BVA with P1-P1 angle was 0.89. Conclusion:The shape of aneurysms, BVA and P1-P1 angle are independent risk factors for BTA rupture. BTA are prone to rupture when the shape of aneurysm is irregular, BVA>76.7 ° and P1-P1 angle<158.5 °.

Objective To evaluate the efficacy of interventional therapy for advanced pancreatic carcinoma. Methods 33 cases of advanced pancreatic carcinoma accepted interventional therapy from April 2005 were retrospectively analyzed. All patients were unoperable and accepted one or more times of celiac and superior mesenteric arterial chemotheraputics perfusion with dosage of 2:1. The embolization was further introduced with the addition of liver invasion. The repetition interval was kept at 6 weeks with no severe complications. Results The one with follow-up CT imagings showed obvious decrease of the lesion size, together with release or disappearance of the sensation of abdominal pain and abdominal distention. The life span prolonged with average survival of 13 months, including the longest of 22 months and the life quality improved. Conclusions The interventional therapy could be the first method of choice in the management of advanced pancreatic carcinoma.

Objective To evaluate the feasibility of multi-parameter MRI in diagnosing ovarian endometrial cysts. Methods Pelvic MRI of 68 patients with confirmed pathological diagnosis were retrospectively reviewed. The patients were divided into ovarian endometriosis (35 patients with 42 lesions, group A) and other cystic lesions (33 patients with 38 lesions , group B).The signal intensity value of T1WI, T2WI of cyst fluid and iliopsoas, ADC value, phase values and R2*values were obtained, cyst fluid/iliopsoas ratios (T1R and T2R) were calculated. The non-parametric Mann-Whitney U test was employed to compare parameter values between the two groups. The values of diagnostic performance were analyzed by using receiver operating characteristic curve (ROC). Use the Logistics regression parameters of diagnostic efficacy to select the highest Youden index for the best parameter association after combining the parameters step by step. Results The median of T1R, T2R, ADC, phase, T1R and R2*values for group A were 3.39, 5.28, 1.20×10-3 mm2/s,2.19×10-2, 15.08 Hz respectively, and that of group B were 0.91, 10.85, 2.64×10-3mm2/s,2.67×10-2, 3.01 Hz, respectively. There were statistically significant difference between the two groups (P<0.01).The AUC of T1R, T2R, ADC value, phase values and R*2 value were 0.930, 0.874, 0.891, 0.685 and 0.924 respectively, and there was no difference among them (P>0.05). When combining T1R, ADC value, R2*value together, the Youden index (0.849 7) was highest. Conclusion Combining T1R, ADC and R2* values can provide an effective way to discriminate endometrial ovarian cyst from other ovary cystic lesions.

Objective To investigate the prevalence of sexual dysfunction in aged men and associated risk factors in Beijing. Methods A cross-sectional study was performed in communities of Beijing involved 1656 men aged over 50 years.The International Index of Erectile Function-5 (IIEF-5),Brief Male Sexual Function Inventory for Urology ( O'Leary 1995 ) and the International Prostate Symptom Score (IPSS)questionnaires was recorded.The body mass index (BMI),prostate size was measured.The survey was conducted to make sure if the patients had diabetes,high blood pressure,hyperlipidemia,cerebrovascular history,and smoking and drinking situation.Pearson's X2 test and unconditional logistic regression were used to investigate the factors associated with sexual dysfunction. Results 1644 subjects were enrolled.The incidence of ED,reduction of sexual desire and defective ejaculation was 90.45％,60.04％ and 38.81％ respectively,and significantly different according to age ( P ＜ O.05 ). Age was positively correlated with ED (3 =0.12,P＜0.05),reduction of sexual desire (β =0.10,P＜0.05) and defective ejaculation (β =0.10,P ＜ 0.05 ) ; ED was significantly associated with BMI (β =0.07,P ＜ 0.05 ).Hypertension and prostate size were risk factors for reduction of sexual desire and defective ejaculation; There was correlation between drinking and defective ejaculation ( β =- O.31,P ＜ 0.05 ). Conelusions Compared with high prevalence of ED and lower sexual desire,the incidence of defective ejaculation were lower; this may reflect the sexual activities of aged male were more active compared with the less success of really erection.The prevalence of ED,reduction of sexual desire or defective ejaculation increased with age.BMI was the risk factor for ED.Enlarged prostate and hypertension was associated with reduction of sexual desire,and drinking was the risk factor for defective ejaculation.

BACKGROUND:The blood loss and the need of blood transfusion after bilateral total knee arthroplasty are very high. Therefore, the use of medicine such as tranexamic acid in total knee arthroplasty is overheated in recent years. Tranexamic acid has been proved to be able to decrease the blood loss after total knee arthroplasty, while the study of its use in bilateral total knee arthroplasty is seldom. OBJECTIVE:To observe the effect and safety of tranexamic acid on perioperative blood loss and the change of hemoglobin in patients undergoing bilateral total knee arthroplasty. METHODS: We selected 69 patients who received bilateral total knee arthroplasty and divided them into two different groups randomly. The patients in the experimental group were given 1 g of tranexamie acid dissolved in 100 mL of 5% glucose solution through intravenous infusion. Those in control group were only given 5% glucose solution 100 mL. Total blood loss, intraoperative blood loss, the hidden blood loss, amount of postoperative drainage, the ratio of blood transfusion, hemoglobin, D-dimer, prothrombin time and activated partial thromboplastin time were studied and compared between the two groups. We also observed the incidence of thrombotic events between the two groups. RESULTS AND CONCLUSION:The blood loss of the experimental group was significantly lower compared to the control group (t=2.194-2.908,P < 0.05). The blood transfusion rate of experimental group was significantly lower compared to the control group (χ2=5.219,P=0.022). The hemoglobin of the experimental group was significantly higher than that of the control group at 3 and 5 days after replacement (t=-3.481, 2.319,P < 0.05). No significant difference in prothrombin time and activated partial thromboplastin time was detectable between the two groups before and after replacement (P > 0.05). Thrombotic events were not visible in both groups. Venous ultrasonography in the lower extremity did not reveal deep venous thrombosis. Above results suggest that tranexamic acid can significantly reduce intraoperative blood loss in patients undergoing bilateral total knee arthroplasty, decreases the requirement of blood transfusion and the dynamic change of hemoglobin, and does not increase the risk of thrombosis.
