Objectives To evaluate the effect of endovascular treatment for spontaneous isolated dissection of the superior mesenteric artery (SIDSMA).Methods There were 41 men and 7 women patients, aged at 32-78 years.46 patients presented with abdominal pain and 3 patients was asymptomatic.The SIDSMA was diagnosed by computed tomography angiography(CTA).Results In the 45 symptomatic patients, one was treated by laparotomy, SMA thrombectomy and necrotic bowel resection.44 patients underwent endovasular treatment, among them 2 patients failed endovasular procedure.The other 42 patients underwent successful intravascular remolding.3 asymptomatic patients underwwent conservative treatment.During the mean (17 ± 4)month follow-up period, computed tomography angiography showed patent true lumen in all the 42 patients.The 2 patients in which the endovascular intervention failed remain symptomatic of recurrent abdominal pain and digestive dysfunction.Conclusions The endovascular interventional therapy is safe and effective for SIDSMA.

Heart failure with high prevalence is the endpoint of many cardiovascular diseases. Once diagnosed, patients usually need lifelong medication, which seriously affects their quality of life. The drugs commonly used to treat heart failure include angiotensin-converting enzyme inhibitors, beta-blockers, aldosterone receptor antagonists, and diuretics. However, the long-term use of those drugs can lead to side effects such as hypotension, depletion of body fluid, and electrolyte imbalance and even increase mortality. According to the theory of traditional Chinese medicine (TCM), Qi deficiency and blood stagnation is the major cause of heart failure and when Qi is not moving, blood is not flowing. Therefore, the TCM clinical treatment of heart failure uses the Chinese medicinal materials which replenish Qi, activate blood, and dispell stasis to treat both internal cause and external symptoms. Recent studies have demonstrated that Chinese herbal medicines such as Astragali Radix, Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Angelicae Sinensis Radix, as well as the compound formulas such as Buyang Huanwutang, Simiao Yongantang, Qili Qiangxin capsules, and Qishen Yiqi drops, play a significant role in the prevention and treatment of heart failure via replenishing Qi, activating blood, and dispelling stasis. Inhibition of oxidative stress and inflammatory responses, mitigation of myocardial fibrosis, improvement of calcium cycling, and protection of mitochondrial function represent the key mechanisms for the treatment of heart failure with Chinese medicinal materials. Focusing on the pathogenic mechanisms and signaling pathways of heart failure, this paper systematically describes the pharmacological effects, molecular mechanisms, and research progress in the clinical application of Chinese medicinal herbs with effects of replenishing Qi, activating blood, and dispelling stasis and their compound formulas in the prevention and treatment of heart failure, aiming to provide scientific evidence for the development and clinical use of anti-heart failure Chinese medicinal materials.

OBJECTIVE:
To analyze the efficacy of integrated minimally invasive surgery for iliac vein compression syndrome with varicose veins of lower extremities.
METHODS:
From January 2017 to January 2018, 11 patients with iliac vein compression syndrome accompanied by varicose veins of lower extremities underwent left iliac vein stent implantation and radiofrequency thermal ablation of lower extremity veins in the First Affiliated Hospital of Zhejiang University School of Medicine. The left iliac vein stent was implanted through the puncture point approach of the main great saphenous vein, and then radiofrequency thermal ablation of the main saphenous vein was performed. Rivaroxaban and aspirin were administered from the day of surgery for 6 months and 12 months, respectively. After discharge, patients were followed up for more than 6 months. The lower extremity veins, iliac veins were reexamined by Doppler ultrasound or CT angiography at 2 weeks, 2 months and 6 months after surgery.
RESULTS:
The operations were successfully performed in 11 patients, and no complication was observed during the operation. The rates of soreness and swelling remission, pigmentation and skin quality improvement, and the iliac vein stent patency were 100%. No varicose vein recurrence, iliofemoral vein thrombosis and pulmonary embolism were found.
CONCLUSIONS
Integrated minimally invasive surgery is safe, effective and less invasive for iliac vein compression syndrome with varicose veins of lower extremities.

Circadian rhythm disruption is a universal phenomenon that is associated with a combination of internal and external factors, with internal factors referring to disturbances in the intrinsic regulatory mechanisms of sleep-wake behavior, and external factors including changes in sleep habits, severe sleep deprivation, shift work, social jet lag, prolonged exposure to nighttime light, and late nighttime eating. Shift work, as a common occupational factor, can lead to disruption of the central/ peripheral biological clock which regulates the expression of almost the entire genome, and the disruption of the biological clock can lead to genetic variants, hormonal secretion abnormalities, insulin resistance, oxidative stress, and systemic inflammation, which are risk factors for obesity. In the context of rapid advancement of global economy and industrialization, the prevalence of simple obesity in the traditional cognitive category is increasing in a linear trend, while the incidence of abdominal obesity, which is closely related to metabolic disorders, is also showing an increasing trend. In recent years, the mechanism of circadian rhythm disorder and obesity associated with shift work has attracted much attention, and this article summarized the latest research progress, aiming to provide a basis for the prevention and treatment of obesity caused by circadian rhythm disruption due to shift work.
