To explore the effects of artisense IRAK-2 oligonucleotide on the prostacyclin (PGI2) synthesis in human umbilicalvein endothelial cells (HUVEC) induced by interleukin-1 (IL-1) and tumor necrosis factor (TNF).Methods:The HUVECs were transfectedwith antisense interleulkin-1 receptor associated kinase-2 oligonucleotide (IRAK-20DN) and stimulated with IL-1 and TNF. The levels of PGI2release were analyzed by competitive ELISA. Results: Pre-transfection with antisense IRAK-20DN could remarkably decrease the levels ofPGI2 synthesis induced by IL-1 in time- and dose-dependent manner, whereas it could not attenuate the one stimulated by TNF. Conclusion:The response of antisense IRAK-2 ODN to IL-1 and TNF-stimulated PGI2 release were different. IRAK-2 plays a key role in the IL-1 signalingevents leading to PGI2 release.

Objective To observe the effect of Yingliu mixture combined with methimazole on autoantibodies and traditional Chinese medical syndromes of patients with Graves’ disease ( GD) . Methods A randomized, paralleled and controlled trial was carried out in 92 GD patients. The patients were evenly randomized into treatment group and control group, and were separately treated with Yingliu mixture combined with methimazole, and methimazole. The treatment for both groups lasted 12 weeks, and forty patients in each group completed the whole treatment. The changes of thyroid function, thyroid autoantibodies, and traditional Chinese medical syndrome scores were observed before and after treatment, and the clinical efficacy was also evaluated. Results (1) After treatment for 12 weeks, serum levels of thyroid peroxidase antibody (TPOAb), thyroglobulin antibody ( TGAb) and thyrotrophin receptor antibody ( TRAb) were decreased, and thyroid stimulating hormone ( TSH) was increased obviously in both groups after treatment ( P<0.01 compared with those before treatment) . The treatment group has better effect on improving TGAb and TRAb than the control group ( P<0.05). ( 2) Compared with those before treatment, the total scores of clinical symptoms and signs were decreased in the two groups at different time points of treatment course ( P<0.001) , and the decrease value in the treatment group was larger than that in the control group ( P<0.05) . ( 3) The total effective rate of the treatment group was 92.50%, higher than 82.50% of the control group ( P<0.05) . Conclusion Yingliu mixture combined with methimazole is effective on improving thyroid function, decreasing autoantibodies levels and relieving clinical symptoms and signs, and has better effect than methimazole alone for the treatment of GD.

Objective To study the management of vascular injury.Methods Retrospective analysis was made on the clinical data of 59 cases of vascular injury,including 55 cases of vascular injury in neck and(extremity) and 4 cases of portal vein and vena cava injury.Among them,21 cases had femoral artery injury with infection and 4 cases had vascular injury due to intervention therapy.All patients with vascular wound of extremity or neck had undergone hemostasis by compression and antishock treament before hospital admission.All cases of femoral artery injury with infection underwent hemostasis by arterial ligation and incision and(drainage) of abscess.Vascular anastomosis was performed in 11 cases,vascular grafting in 12 cases,and(vascular) repair in 14 cases.Results There were 2 deaths.5 cases had amputation(including a case of(femoral) embolism due to intervention trerapy).Postoperative intermittent claudication,decreased skin(temperature) and other signs of ischemia occurred in 21 cases of femoral artery injury with infection,but none developed limb gangrene. The other cases were discharged in good health.Conclusions In the treatment of vascular injury,wound hemostasis and antishock treatment should be done first to save the patient′s life and the management of the vascular injury depends on the situation,with the aim to try by all means to save the extremity.Vascular reconstruction is the main method for treatment of vassular injury.Vascular ligation can be done in cases of femoral artery injury with infection.

Objective To summarize the experience in the diagnosis and treatment of hepatic trauma. Methods The clinical data of 260 patients with hepatic trauma admitted from January 1988 to December 2007 were retrospectively reviewed with regard to degree of trauma, treatment methods, therapeutical effects, complications and SO on. Results One hundred and fifty-three eases were treated by operative management,1 07 cases by nonoperative management.236 cases were cured,24 cases died,and the case fatality rate was 10.2%.There were no death among 139 patients with hepatic trauma grades Ⅰ～Ⅱ,22 death among 119 grades Ⅲ～Ⅴ patients, all death of 2 in grade VI, which demonstrated the correlation between death and hepatic trauma grade was statistically significant. Complications appeared in 82 eases, mainly including Secondary hemorrhage, abdominal infection and so on. Conclusions Nonoperative management is suitable for hepatic trauma with stable hemodynamics. Operative management is rapidly selected when the hemodynamics aren't stable. The cooperation of many specialities can enlarge the application of nonoperative management and decrease complications.

Objective To explore the effect of health education based on interactive 3D-modeling of intracranial artery on interventional diagnosis and treatment for patients with intracranial artery stenosis.Methods A total of 70 patients requiring interventional diagnosis and treatment due to intracranial artery stenosis admitted to our department in 2022 were enrolled,and randomly divided into observation group and control group,with 35 cases in each group.Their stenotic sites of intracranial arteries included the vertebral and middle cerebral arteries.The observation group received the preoperative conventional education mode combined with interactive 3D-modeling to carry out health education,while the control group got the unified education sheet and slides to carry out routine preoperative health education.A self-made publicity and education effectiveness rating scale was used to score before and after the publicity and education,and their scores of awareness of intracranial artery stenosis,awareness of treatment plans,and satisfaction with medical treatment were compared between the 2 groups.Results Before the health education,there was no statistical differences in their awareness scores concerning intracranial vessels(normal intracranial arteries,intracranial arterial occlusion,and vascular stenosis treatment)between the 2 groups patients.After the implementation of education,the awareness scores of intracranial vessels were elevated in both groups,but the awareness scores of the normal intracranial artery,intracranial artery occlusion,vascular stenosis treatment,and treatment satisfaction were significantly higher in the observation group than the control group(P＜0.05).Moreover,the patients with middle cerebral artery and vertebral artery stenosis from the observation group obtained obviously higher propaganda score than those from the control group(P＜0.05).Conclusion The health education model combined with 3D-modeling can improve the patient's awareness of the diagnosis and treatment of intracranial artery stenosis,promote their satisfaction of medical treatment,and thus increase their compliance and the rate of interventional diagnosis and treatment,and then finally,prevent strokes caused by intracranial artery stenosis.

Objective To investigate the value of optical trocar insertion technique in establishing pneumoperitoneum in patients undergoing laparoscopic surgery after previous abdominal surgery. Methods A total of 29 patients, with a history of abdominal surgery, who planned to undergo laparoscopic liver surgery were enrolled and randomly divided into optical trocar insertion group and open approach group. The independent samples t -test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the Fisher's exact test was used for comparison of categorical data between groups; the Mann-Whitney U test was used for comparison of ranked data between groups. Results There were no procedure-related complications in either group. Compared with the open approach group, the optical trocar insertion group had a significantly shorter time required to establish pneumoperitoneum [35.00 (21.00-46.00) seconds vs 180.00 (152.50-252.50) seconds, U =0, P < 0.001] and a significantly smaller incision length [1.10(1.00-1.20) cm vs 2.80(2.45-3.00) cm, U =0, P < 0.001]. Conclusion Both optical trocar insertion and open approach for establishing pneumoperitoneum is relatively safe in patients undergoing laparoscopic liver surgery after previous abdominal surgery, while optical trocar insertion has the advantages of high efficiency and minimal invasiveness in establishing pneumoperitoneum.
