Diabetes, hypertension, and dyslipidemia, collectively referred to the " Three Highs, " represent increasingly prevalent metabolic risk factors in China. Many individuals experience all three conditions concurrently, significantly heightening the risk of cardiovascular disease and mortality. Although the National Metabolic Management Center(MMC) has been established for over eight years and has its unique features, the awareness, treatment, and control rates of these diseases in China remain low, and the efficiency of community management is insufficient. According to the previous two editions of management guidelines and the most recent domestic and international diagnostic and treatment guidelines, this paper conducts an in-depth analysis of the operational experience and management strategies of the MMC. Its aim is to improve the efficiency of grassroots MMC mode management for " Three Highs" patients and ensure that patients receive more standardized management.

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 explore the correlation between intraoperative cooling temperature and postoperative neurological prognosis in aortic arch surgery.Methods:We observed and collected data from 118 patients who underwent open arch replacement surgery by a single surgeon with mild-to-moderate hypothermic circulatory arrest, from January 2017 to December 2020, in Beijing Anzhen Hospital. According to the bladder temperature during the circulation arrest, 118 patients were divided into 3 groups: T1 group[n=39, (25.58±0.64)℃]; T2 group[n=39, (28.21±0.77)℃]; T3 group[n=40, (30.95±0.97)℃]. Clinical data and operative data were analyzed to assess difference between these 3 groups. Analyze the risk factors of postoperative neurological complications, and explore further the correlation between intraoperative core temperature and postoperative neurological prognosis.Results:Among the 118 patients, the average operation, cardiopulmonary bypass (CPB), block, circulatory arrest, and selective cerebral perfusion (SCP) time were 6.64 h, 188.5 min, 104.19 min, 23.93 min, 28.81 min, respectively. The in-hospital death occurred in 8 patients(6.78%), and permanent neurological dysfunction (PND) in 13 patients(11.02%), transient neurological dysfunction (TND) in 25 patients(21.19%). There was no significant difference in the deaths among the three groups. The incidence of TND and PND in the T3 group was significantly reduced ( P=0.042; P=0.045). In addition, the volume of drainage during the first 24 h and the incidence of re-exploration for bleeding had a relatively obvious decreasing trend ( P=0.005; P=0.012). Through multiple regression analysis, under the adjusted model, the core temperature was independently correlated with the incidence of postoperative PND ( OR=0.51; 95% CI: 0.27-0.97; P=0.0389); in group comparison, the relatively higher core temperature was an independent protective factor for postoperative PND ( OR=0.04; 95% CI: 0.00-0.91; P=0.0434). Conclusion:Our research had preliminary proved that in the open arch replacement surgery, mild hypothermia can reduce the incidence of some complications of deep hypothermia, at the same time improve the prognosis of the neurological prognosis, reduce the incidence of postoperative PND.

Arabidopsis thaliana is an important and long-established model species for plant molec-ular biology,genetics,epigenetics,and genomics.However,the latest version of reference genome still contains a significant number of missing segments.Here,we reported a high-quality and almost complete Col-0 genome assembly with two gaps(named Col-XJTU)by combining the Oxford Nanopore Technologies ultra-long reads,Pacific Biosciences high-fidelity long reads,and Hi-C data.The total genome assembly size is 133,725,193 bp,introducing 14.6 Mb of novel sequences compared to the TAIR1 0.1 reference genome.All five chromosomes of the Col-XJTU assembly are highly accurate with consensus quality(QV)scores＞60(ranging from 62 to 68),which are higher than those of the TAIR10.1 reference(ranging from 45 to 52).We completely resolved chro-mosome(Chr)3 and Chr5 in a telomere-to-telomere manner.Chr4 was completely resolved except the nucleolar organizing regions,which comprise long repetitive DNA fragments.The Chr1 cen-tromere(CEN1),reportedly around 9 Mb in length,is particularly challenging to assemble due to the presence of tens of thousands of CEN180 satellite repeats.Using the cutting-edge sequencing data and novel computational approaches,we assembled a 3.8-Mb-long CEN1 and a 3.5-Mb-long CEN2.We also investigated the structure and epigenetics of centromeres.Four clusters of CEN180 monomers were detected,and the centromere-specific histone H3-like protein(CENH3)exhibited a strong preference for CEN 180 Cluster 3.Moreover,we observed hypomethylation patterns in CENH3-enriched regions.We believe that this high-quality genome assembly,Col-XJTU,would serve as a valuable reference to better understand the global pattern of centromeric polymorphisms,as well as the genetic and epigenetic features in plants.

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 prospectively assess clinical characteristics, potential causes and prognosis in patients with persistent inflammation, immunosuppression and catabolism syndrome (PICS) after polytrauma.Methods:Totally 1 083 patients with polytrauma admitted to Department of Traumatic Surgery of Tongji Hospital from Janury 2019 to July 2020 were enrolled. Exclusion criteria included age<18 years old, length of hospital stay<15 days, previous medical history of malignancy, or immunological, consumptive, and metabolic diseases. According to the diagnostic criteria of PICS, all enrolled patients were divided into two groups: PICS group and N-PICS group (without PICS). The patient’s clinical characteristics, ISS score, GCS score, SOFA score, and prognosis were collected. The χ2 test or Student’s t test was uesd to compare the difference between the PICS group and N-PICS group. Results:The incidence of PICS in patients with polytrauma was 11.7% (127/1 083). The majority of PICS patients were middle-aged and elderly men, 68.5% with traumatic brain injury and 59% with thoracic injury. GCS score was significantly lower, while ISS, APACHE II and SOFA scores were significantly higher in the PICS group than in the N-PICS group ( P<0.01, P<0.05). Among PICS patients, 79.5% were treated with mechanical ventilation and 76.3% were associated with pulmonary infection, with a 28-day mortality of 5.5% and a 180-day mortality of 16.5%, which were siginifcantly different from those without PICS. Conclusions:PICS has a high incidence after polytrauma and is commonly seen in middle-aged and elderly male patients with severe polytrauma, especially accompanied by traumatic brain injury or/and thoracic injury. Patients with PICS after polytrauma have poor long-term prognosis, so early identification and intervention should be strengthened in clinical practice.

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 observe the clinical effect of isosorbide mononitrate combined with metoprolol in the treatment of coronary heart failure.Methods From January 2015 to May 2017,100 patients with coronary heart failure treated in the Second People's Hospital of Yuyao were randomly divided into two groups according to the digital table,with 50 cases in each group.The conventional group was treated with conventional therapy.The observation group was treated with isosorbide mononitrate combined with metoprolol on the basis of conventional treatment for 30 days.The clinical efficacy,cardiac function index and plasma BNP level were compared between the two groups.Results The total effective rate of the observation group was 96.0％ (48/50),which was higher than 78.0％ (39/50) in the conventional group(x2 =7.161,P ＜ 0.01).After treatment,the cardiac drainage index(CI) [(3.14 ± 0.53) L · min-1 · (m2)-1],cardiac output blood volume (CO) [(5.62 ± 0.95) L/min],each stroke volume (SV) [(79.24 ± 2.56) mL],left ventricular ejection fraction (LVEF) [(61.62 ± 4.95) ％] in the observation group were better than those in the conventional group[(2.41 ±0.45) L · min-1 · (m2)-1,(4.79 ± 0.23) L/min,(72.30 ± 2.78)mL,(53.79 ±4.23)％,t =7.043,5.696,12.318,8.066,all P ＜0.05].The BNP level of the observation group was (172.17 ± 10.36) pg/mL,which was lower than (215.47 ± 12.48) pg/mL of the conventional group (t =17.908,P ＜ 0.05).Conclusion The treatment of coronary heart failure with isosorbide mononitrate and metoprolol can improve the clinical effect and improve cardiac function.
