Objective To assess the efficacy and safety of ascending aorta banding technique combined with typeⅠhybrid aortic arch repair for the aortic arch diseases. Methods The clinical data of patients undergoing ascending aorta banding technique combined with type Ⅰ hybrid arch repair for aortic arch diseases from March 2019 to March 2022 in Beijing Anzhen Hospital were retrospectively analyzed. The technical success, perioperative complications and follow-up results were evaluated. Results A total of 44 patients were collected, including 35 males and 9 females, with a median age of 63.0 (57.5, 64.6) years. The average EuroSCORE Ⅱ score was 8.4%±0.7%. The technical success rate was 100.0%. All patients did not have retrograde type A aortic dissection and endoleaks. One patient died of multiple organ failure 5 days after operation, the in-hospital mortality rate was 2.3%, and the remaining 43 patients survived and were discharged from hospital. The median follow-up period was 14.5 (6-42) months with a follow-up rate of 100.0%. One patient with spinal cord injury died 2 years after hospital discharge. One patient underwent thoracic endovascular aortic repair at postoperative 3 months due to new entry tears near to the distal end of the stent. Conclusion Ascending aorta banding combined with typeⅠhybrid arch repair for the aortic arch diseases does not need cardio-pulmonary bypass. Ascending aorta banding technique strengthens the proximal anchoring area of the stent to avoid risks such as retrograde type A dissection, endoleak and migration. The operation owns small trauma, rapid recovery, low mortality and a low rate of reintervention, which may be considered as a safe and effective choice in the treatment of the elderly, high-risk patients with complex complications.

OBJECTIVE: To investigate whether meranzin hydrate (MH) can alleviate depression-like behavior and hypomotility similar to Chaihu Shugan Powder (CSP), and further explore the potential common mechanisms. METHODS: Totally 120 Spraque-Dawley rats were randomly divided into 5-8 groups including sham, vehicle, fluoxetine (20 mg/kg), mosapride (10 mg/kg), CSP (30 g/kg), MH (9.18 mg/kg), [D-Lys3]-GHRP-6 (Dlys, 0.5 mg/kg), and MH+Dlys groups by a random number table, 8 rats in each group. And 32 mice were randomly divided into wild-type, MH (18 mg/kg), growth hormone secretagogue receptor-knockout (GHSR-KO), and GHSR+MH groups, 8 mice in each group. The forced swimming test (FST), open field test (OFT), tail suspension test (TST), gastric emptying (GE) test, and intestinal transit (IT) test were used to assess antidepressant and prokinetic (AP) effects after drug single administration for 30 min with absorbable identification in rats and mice, respectively. The protein expression levels of brain-derived neurotrophic factor (BDNF) and phosphorylated mammalian target of rapamycin (p-mTOR) in the hippocampus of rats were evaluated by Western blot. The differences in functional brain changes were determined via 7.0 T functional magnetic resonance imaging-blood oxygen level-dependent (fMRI-BOLD). RESULTS: MH treatment improved depression-like behavior (FST, OFT) and hypomotility (GE, IT) in the acute forced swimming (FS) rats (all P<0.05), and the effects are similar to the parent formula CSP. The ghrelin antagonist [D-Lys3]-GHRP-6 inhibited the effect of MH on FST and GE (P<0.05). Similarly, MH treatment also alleviated depression-like behavior (FST, TST) in the wild-type mice, however, no effects were found in the GHSR KO mice. Additionally, administration of MH significantly stimulated BDNF and p-mTOR protein expressions in the hippocampus (both P<0.01), which were also prevented by [D-Lys3]-GHRP-6 (P<0.01). Besides, 3 main BOLD foci following acute FS rats implicated activity in hippocampus-thalamus-basal ganglia (HTB) circuits. The [D-Lys3]-GHRP-6 synchronously inhibited BOLD HTB foci. As expected, prokinetic mosapride only had effects on the thalamus and basal ganglia, but not on the hippocampus. Within the HTB, the hippocampus is implicated in depression and FD. CONCLUSIONS MH accounts for part of AP effects of parent formula CSP in acute FS rats, mainly via ghrelin-related shared regulation coupled to BOLD signals in brain areas. This novel functionally connection of HTB following acute stress, treatment, and regulation highlights anti-depression unified theory.

Objective:To explore the application of cannulating the ischemic femoral and right axillary artery in Sun’s procedure for acute type A aortic dissection with lower extremity ischemia.Methods:Twelve patients of acute Stanford type A aortic dissection complicated by lower extremity ischemia were analyzed retrospectively between July 2017 and May 2019, and the right axillary and ischemic femoral artery were used for cardiopulmonary bypass. All the 12 patients were male and categorized as the complicated Stanford type A aortic dissection. The mean age was(48.4±8.4)years, and the median time from symptom onset to emergency operation was 24.00(18.50, 43.25)hours. Eleven patients presented with unilateral extremity ischemia, while bilateral extremity ischemia occurred in one. The prosthetic vessel, with a diameter of 8 mm, was anastomosed to the ischemic femoral artery via an end-to-side way. Both the right axillary artery and the prosthetic vessel were cannulated for CPB. For the proximal dissection in this cohort of patients, we performed Bentall procedure in 5 cases, ascending aortic replacement in 3, and the aortic valve commissure reconstruction with ascending aortic replacement in 4. Total arch replacement with stented elephant trunk implantation were carried out for arch and descending aortic lesion in 12 cases.Results:Early mortality was 8.3%(1/12). The time of CPB, aortic clamp, circulatory arrest, and selective cerebral perfusion averaged(204.6±26.3) min, (114.6±16.6) min, (23.4±8.5) min, and(33.5±11.0) min, respectively. Five patients underwent concomitant bypass procedures, including: ascending aorta-bilateral femoral artery bypass in 1, ascending aorta-right femoral artery bypass in 3, ascending aorta-left femoral artery bypass in 1. Acute renal failure with continuous renal replacement therapy occurred in 4 cases, re-thoratomy for hemaostsis in 1, and re-intubation in 1. One patient developed osteofascial compartment syndrome after aortic repair, and consequent left lower extremity compartment fasciotomy was performed. The mean follow-up time was(17.2±7.6)months, and no aortic-related adverse event was detected during follow up.Conclusion:To acute Stanford type A aortic dissection with lower extremity ischemia, cannulating the ischemic femoral and right axillary artery in Sun’s procedure were associated with lower perioperative mortality and better prognosis.

Objective:To evaluate the application of moderate hypothermia circulatory arrest(MHCA)with a higher temperature(29℃) and bilateral selective antegrade cerebral perfusion(bSACP) in acute Stanford type A aortic dissection(TAAD] treated by total arch replacement with stented elephant trunk implantation.Methods:From July 2019 to January 2020, fifteen patients of acute TAAD undergoing emergent operations via MHCA with a core temperature of 29℃ and bSACP were analyzed retrospectively(modified group), and 26 patients treated by MHCA(25℃) and unilateral selective antegrade cerebral perfusion(uSACP) during the same period were defined as the traditional group. All cases were complicated type A dissection. The mean age in this cohort was 49 years, and 32 patients(78%) were male. Thirty six patients(87.8%) suffered from arterial hypertension. The proximal manipulations included: aortic sinus repair in 13 cases(31.7%), ascending aortic replacement in 29(70.7%), Bentall in 12(29.3%). Total arch replacement with stented elephant trunk implantation was performed in all cases.Results:The in-hospital death occurred in 2(4.9%), and cerebral infarction in 3(7.3%), transient neurologic deficit in 5(12.2%), paraplegia in 2(4.9%). The ratios of above-mentioned adverse events in the traditional and modified group were[2(7.7%) vs. 0, P=0.524], [3(11.5%)vs. 0, P=0.287], [4(15.4%) vs. 1(6.7%), P=0.636], [1(3.8%) vs. 1(6.7%), P=1.000] respectively. The major adverse events in the modified group were transient neurologic deficit and paraplegia in 1 each. Compared with the traditional group, the time of operation, CPB, cardiac arrest, circulatory arrest of the lower part, anterograde low flow cerebral perfusion, mechanical ventilation and ICU stay was shorter. The drainage of 48 hours after surgery was less also. The differences in new acute renal failure requiring CRRT and re-sternotomy for bleeding between groups were not statistical significance. Conclusion:The early results of MHCA(29℃) and bSACP applied in total arch replacement with stented elephant trunk implantation for acute TAAD were satisfactory. The time of mechanical ventilation and ICU stay was shorter in the modified group, and the drainage of 48 hours after surgery was less also.

OBJECTIVE：To study the effects of different amounts of Euphorbiae Semen fatty oil in self-assembly micelles on intestinal absorption of 4 kinds of euphorbia （euphorbia L 1，L2，L3，L8）in rats. METHODS ：The self-assembled micelle solution containing 4 kinds of euphorbia was prepared by adding 4 kinds of euphorbia （40 mg/L）in excess ，using the fatty oil of Euphorbia Semen（0.2，0.4，1，4 g/L）and sodium deoxycholate as carriers. Totally 60 rats were collected to establish in-situ one-way intestinal perfusion model. Different intestinal segments （duodenum，jejunum，ileum，colon）were perfused with drug-containing intestinal perfusion fluid according to different dosage of Euphorbiae Semen fatty oil. HPLC method was adopted to determine the contents of 4 kinds of euphorbia in the intestinal perfusate before and after perfusion. The absorption rate constant （Ka）and apparent absorption coefficient （Peff）of 4 kinds of euphorbia in different intestinal segments were calculated. The ileum segment with better absorption was selected as the object to investigate and calculate the ac cumulative absorption of 4 kinds of euphorbia. RESULTS：The self-assembled micelles formed by different concentrations of fatty oil of Euphorbiae Semen could significantly increase the absorption of 4 kinds of euphorbia in different intestinal segments to different extents. When the dosage of Euphorbiae Semen fatty oil was 0.4 g/L，the intestinal absorption effect of 4 kinds of euphorbia were all the best ；the Peff was significantly increased，compared with no fat oil group （P＜0.05 or P＜ . According to the order of Ka and Peff of each intestinal ： segment in different fatty oil dosage groups ，the absorption 0531-89628590。E-mail：1310394709@qq.com effect of 4 kinds of euphorbia in each intestinal segment was the best in jejunum and the worst in colon. Compared with no fatty oil group ，when the amount of Euphorbiae Semen fatty oil w as 0.2-4 g/L，accumulative amount of 4 kinds of euphorbia in the ileum of rats increased significantly （P＜0.05 or P＜0.01）， and the highest in 0.4 g/L Euphorbiae Semen fatty oil group. CONCLUSIONS ：The self-assembly micelle s composed of Euphorbiae Semen fatty oil and deoxycholate can increase the absorption of euphorbia L 1，L2，L3，L8 in each intestinal segment to different extent，and the jejunum is the main absorption segment.

Objective: To examine the outcomes of surgical treatment in patients of type Stanford A aortic dissection with Kommerell′s diverticulum. Methods: From January 2009 to August 2017, patients of type Stanford A aortic dissection with Kommerell′s diverticulum who underwent the Sun procedure were enrolled. Patient demographic, preoperative, intraoperative, early morbidity and mortality data were collected from medical and electronic patient records.

Objective To confirm the impact of renal malperfusion on early and late outcomes of patients undergoing sur-gery for type A aortic dissection(TAAD). Methods From June 2011 to July 2012,a total of 165 TAAD patients undergoing surgery in hospital were enrolled and divided into 2 groups based on the results:research group(complicated with renal malper-fusion),control group(without renal malperfusion). A cohort follow-up project was conducted among these patients. The pri-mary outcome was all-cause death. Baseline and operative characteristics,early and late outcomes were analyzed to assess difference between 2 groups. Cumlative survival rates within 72 months among the 2 groups was described with Kaplan-Meier curves. Cox proportional hazards model was used to estimate the hazard ratios(HR)and 95％ confidence intervals(95％ CI)of late mortality among the 2 groups. Results Renal malperfusion was detected in 38(23. 0％)of 165 TAAD patients. 30-day mortality was 15. 8％ and 3. 9％ in patients with and without renal malperfusion(P < 0. 05),respectively. The mean follow-up period was(67 ± 3)months,late survival was 68. 4％ in patients with renal malperfusion and 88. 2％ in patients without(P <0. 05). By Cox proportional hazards model,after adjusting forage,sex,group(acute or chronic),presence of cardiac tampon-ade,brachiocephalic vessels involvement,coronary arteries involvement,root replacement,total arch replacement,concomitant coronary artery bypass grafting(CABG)and other organ-malperfusion,when compared to the control group,the HR(95％ CI) of late mortality was 5. 18( 1. 07 - 5. 18)in the research group. Besides renal malperfusion,concomitant coronary artery bypass grafting was presented as an independent risk factor of long-term survival(HR = 10. 08,95％ CI:2. 28 - 44. 62,P = 0. 002). Conclusion Coexistence of renal malperfusion is associated with a substantially increased risk of death in patients undergoing surgery for TAAD. A more exact stratification that weight every malperfusion-affected organ but not base on the number of malp-erfusion-affected organ simply may be more helpful to TAAD patients with malperfusion syndrome.
