Comparison between Ye Tianshi and Wu Jutong in treatment of summer-heat disease / 中国中药杂志

Through the traditional Chinese medicine inheritance platform system, with the help of medical records, Ye Tianshi and Wu Jutong's medication characteristics for summer heat sickness were analyzed, the laws of the two people's medication were summarized, and the similarities and differences between the two were explored to explore the relationship. As a result, it was found that both of them recognized the relationship between summer heat and wetness, and Wu Jutong believed that "wind" was also an important pathogenic factor. Both of the patients were treated with cold medicine and warm medicine. They used mostly bitter, sweet, pungent taste and lungs, spleen, stomach, and heart meridian are the main components; two are commonly used Armeniacae Semen Amarum, Talcum, Rehmanniae Radix, Ophiopogonis Radix, Pinelliae Rhizoma and other drugs, Ye Tianshi use Scrophulariae Radix, Tetrapanacis Medulla, Coicis Semen and other drugs more, Wu Jutong use Gypsum Fibrosum, Sojae Semen Praeparatum, Menthae Haplocalycis Herba and other drugs more; at the same time, a combination of two high-frequency medicines used by two people has been excavated, and a new prescription has been deduced to provide a reference for further understanding and treatment of summer diseases.

Percutaneous transluminal renal angioplasty with stent is effective for blood pressure control and renal function improvement in atherosclerotic renal artery stenosis patients / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Percutaneous transluminal renal angioplasty with stent is an effective procedure for atherosclerotic renal artery stenosis. However, the decision to perform this procedure has recently raised considerable debate. The aim of this study was to assess the effects of percutaneous transluminal renal angioplasty with stent in atherosclerotic renal artery stenosis patients, especially as it relates to blood pressure control and renal function improvement.</p><p><b>METHODS</b>A retrospective analysis was made of the clinical data from 125 atherosclerotic renal artery stenosis patients who underwent percutaneous transluminal renal angioplasty from July 2004 to June 2008 in the Department of Vascular Surgery of Beijing Chaoyang Hospital. We compared blood pressure, number of oral antihypertensive medications, and renal function changes pre and post-procedure at 24 months follow-up.</p><p><b>RESULTS</b>A total of 125 atherosclerotic renal artery stenosis patients underwent percutaneous transluminal renal angioplasty and 143 stents were placed. At 24 months follow-up, both systolic and diastolic blood pressure and the number of oral antihypertensive medications were significantly reduced (P < 0.05). Overall, the estimated glomerular filtration rate did not change significantly (P > 0.05); however, a significant increase in estimated glomerular filtration rate was observed in the subgroup of patients with a lower baseline estimated glomerular filtration rate and in the subgroup of patients with bilateral renal artery stenosis (P < 0.05).</p><p><b>CONCLUSION</b>Percutaneous transluminal renal angioplasty is a safe procedure for atherosclerotic renal artery stenosis patients, providing a significant improvement in blood pressure control and reduction in the number of oral antihypertensive medications.</p>

Long-term results of endovascular therapy for proximal subclavian arterial obstructive lesions / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Endovascular therapy is a treatment option for localized occlusion of the subclavian artery. In this report the long-term experience with 59 patients is presented.</p><p><b>METHODS</b>Between June 1998 and September 2008, we used endovascular therapy to treat 61 subclavian arterial obstructive lesions in 59 patients (46 males and 13 females, 34 - 82 years of age with a mean age (61.9 + or - 11.0) years). Twenty patients (34%) had clinical symptoms due to vertebrobasilar insufficiency, 26 (44%) had disabling arm ischemia, and 13 (22%) had both symptoms. We performed all procedures under local anesthesia. The approaches were from the femoral artery (n = 47), brachial artery (n = 1, involving bilateral subclavian disease) or both (n = 11). Sixty stents were implanted. All patients were followed-up at 1, 3, 6, and 12 months post-procedure, and annually thereafter.</p><p><b>RESULTS</b>We achieved technical success in 58 (95.1%) arteries, all of which were stented. There were three technical failures; two were due to the inability to cross over an occlusion, necessitating the switch to an axillo-axillary bypass, and the third was due to shock after digital subtraction angiography and prior to stenting. Arterial stenosis pre- and post-stenting was (83.6 + or - 10.8)% and (2.5 + or - 12.5)% (P < 0.01). Clinical success was achieved in 55 of the 59 patients (93.4%). Of the four clinical failures, three were technical and the remaining patient had a stent thrombosis. Systolic blood pressure difference between the two brachial arteries was (44.7 + or - 18.5) vs. (2.2 + or - 3.9) mmHg (P < 0.01). Primary patency was 98% at 12 months, 93% at 24 months, and 82% at 5 years. Five patients were lost to follow-up by 12 months post-stenting. Significant recurrent obstruction developed in five patients with resumption of clinical symptoms. The overall survival rate was 98.2% at 12 months, 89.5% at 24 months, and 84.5% at 5 years.</p><p><b>CONCLUSIONS</b>Endovascular therapy for proximal subclavian arterial obstructive lesions is effective and successful. This minimally invasive treatment may be the first choice of treatment for proximal subclavical arterial obstructive lesions.</p>

Surgical treatment of 154 patients with non-traumatic acute lower limb ischemia / 中华外科杂志

<p><b>OBJECTIVE</b>To analyze the surgical treatment and prognosis of non-traumatic acute lower limb ischemia, and compare the morbidity and prognosis of acute arterial embolism and acute arterial thrombosis.</p><p><b>METHODS</b>The clinical data of 154 acute lower limb ischemia patients surgically treated from July 1999 to December 2007 were retrospectively analyzed. Fogarty catheter embolectomy was used in all patients; in which, 128 cases underwent Fogarty catheter embolectomy only, 8 cases Fogarty catheter embolectomy combined with endarterectomy, 13 cases Fogarty catheter embolectomy combined with vascular reconstruction with prosthetic graft or great saphenous vein, 5 cases Fogarty catheter embolectomy combined with amputation. The patients were divided into two groups according to pathogenesis: acute arterial embolism group (99 cases) and acute arterial thrombosis group (55 cases). The morbidity, amputation, perioperative mortality rates and high risk factors of amputation in the two groups were compared.</p><p><b>RESULTS</b>Female experienced acute arterial embolism more often than man (60.6% vs 39.4%, P < 0.05), and more acute arterial thrombosis occurred in man (72.7% vs 27.3%, P < 0.05). The amputation rate of all cases was 9.7%, and perioperative mortality rate was 11.7%. The amputation rate in acute arterial embolism group was lower than acute arterial thrombosis group (5.1% vs 18.2%, P < 0.05). The perioperative mortality rates in the two groups were equal (11.1% vs 12.7%, P > 0.05). The statistically high risk factor of amputation for two groups was ischemic time, and smoking and diabetes were high risk factors for acute arterial thrombosis.</p><p><b>CONCLUSIONS</b>Men experiences acute arterial thrombosis more often, and women experiences acute arterial embolism more often. The amputation rate of acute arterial embolism is lower than acute arterial thrombosis, and acute arterial thrombosis has more high risk factors of amputation.</p>

Experiences of retroperitoneal approach for aortoiliac reconstruction / 中华外科杂志

<p><b>OBJECTIVE</b>To summarize experiences of aortoiliac reconstruction through retroperitoneal approach.</p><p><b>METHODS</b>Twenty-eight patients underwent retroperitoneal aortoiliac reconstructions, including aortic aneurysmectomy with graft replacement, aortic endarterectomy with patch angioplasty, thoraco-abdominal aortic bypass, resection of retroperitoneal mass with ilio-femoral bypass, iliac aneurysmectomy with aorto-external iliac artery bypass, removal of aortoiliac foreign body, common iliac endarterectomy, aorto (ilio)-femeral bypass and common ilio-femo-popliteal bypass. Drainage tubes were placed retroperitoneally in 24 cases.</p><p><b>RESULTS</b>All operations in this group were successful without perioperative death. The volume of intra-operative bleeding was 100-400 ml (mean 240 ml). Blood transfusion were employed in 2 cases. Retroperitoneal drainage was 50-170 ml (mean 85 ml). Naso-gastric tubes were removed 28 h on average after operation. All patients recovered uneventfully except that cardiac insufficiency, stress ulcer and retroperitoneal hematoma were present in 3 patients respectively. Twenty-two patients were followed up from 3 months to 2.5 years. One patient died of AMI 2 years after operation. One patient receiving ilio-femo-popliteal bypass was found to have occlusion of femo-popliteal segment of prosthetic graft. One patient developed brain hemorrhage 1.5 years postoperatively. All the other followed-up patients were living well.</p><p><b>CONCLUSION</b>Retroperitoneal approach, not violating the peritoneal cavity, offers certain physiological advantages associated with minimal disturbance of gastrointestinal and respiratory function, thereby decreasing respiratory complications and postoperative ileus, avoiding intra-abdominal adhesions with their attendant risk of early and late small bowel obstruction. It proved to be a simple and safe alternative for surgical treatment of aortoiliac diseases.</p>
