OBJECTIVE To conduct a clinical comprehensive evaluation of five marketed thrombopoietin receptor agonists （TPO-RA） approved in China， providing quantitative evidence for drug selection and therapeutic decision-making in medical institutions. METHODS Relevant data on Romiplostim for injection， Eltrombopag olamine tablets， Herombopag olamine tablets， Avatrombopag maleate tablets， and Lusutrombopag tablets were collected. Based on the Chinese Rapid Guide for Drug Evaluation and Selection in Medical Institutions （Second Edition）， 12 formulations of these five TPO-RA were scored quantitatively and comparatively across five dimensions： pharmacological characteristics， efficacy， safety， cost-effectiveness， and other attributes. RESULTS The comprehensive scores of the 12 formulations ranged from 62.56 to 75.50 points， with most scoring ≥70 points. Using the highest-scoring formulation for each generic name as a representative， the overall rankings of the five TPO-RA were as follows： Lusutrombopag tablets （75.50 points）， Eltrombopag olamine tablets （75.10 points）， Avatrombopag maleate tablets （70.40 points）， Romiplostim for injection （63.93 points）， and Herombopag olamine tablets （63.52 points）. Lusutrombopag tablets scored relatively high in pharmacological characteristics， safety， and cost-effectiveness， while Eltrombopag olamine tablets performed well in efficacy and cost-effectiveness. The other formulations showed varying scores across evaluation dimensions. CONCLUSIONS The five TPO-RA demonstrate favorable overall clinical value， with Lusutrombopag tablets and Eltrombopag olamine tablets ranking higher in comprehensive scores， these two drugs should be prioritized in drug selection and formula optimization by medical institutions.

Objective To analyze the clinical efficacy of transcatheter tricuspid valve replacement (TTVR) in cardiac implantable electronic lead-related tricuspid regurgitation (TR). Methods The patients with severe TR who underwent LuX-Valve TTVR in 9 Chinese medical centers from June 2020 to August 2021 were retrospectively enrolled. They were divided into a cardiac implantable electronic device (CIED) group and a non-CIED group based on whether they had pre-existing CIED implantation. Success of the procedure was defined as safe implantation of the LuX-Valve and complete withdrawal of the delivery system. Prognostic improvement was defined as a decrease of TR grade to≤2+ and an improvement of cardiac function by≥2 grades. Surgical success and postoperative prognosis were compared between the two groups. Results A total of 190 patients were collected, including 50 males and 140 females with a mean age of 66.2±7.8 years. There were 29 patients in the CIED group, and 161 patients in the non-CIED group. In the CIED group, 28 patients were implanted with a permanent pacemaker and 1 patient with a cardioverter-defibrillator. Preoperative New York Heart Association (NYHA) cardiac function class, TR degree, left ventricular ejection fraction, tricuspid annular plane systolic excusion, and cardiac risk scores were comparable between the two groups (P>0.05). Postoperative TR was reduced to≤2+ in all patients, and there was no statistical difference in the incidence of perivalvular leakage between the two groups (P=0.270). Postoperative CT of CIED patients showed the valve was in place, and the lead was not extruded, twisted, or deflected. The in-hospital mortality of the two groups were 10.3% and 1.9%, respectively, and the difference was statistically significant (P=0.047). In addition, there was no statistical difference between the two groups in terms of postoperative improvement of cardiac function and mortality in the 1- and 2-year follow-up. Conclusion TTVR is feasible, safe, and effective in patients with CIED implantation, and the pre-existing lead has no significant effect on the clinical efficacy.

Objective:To explore the clinical outcomes of recipients with refractory heart failure requiring an insertion of mechanical circulation support(MCS)device prior to heart transplantation(HT).Methods:From March 2017 to December 2021, retrospective review is performed for clinical data of 7 recipients with refractory heart failure requiring a bridging placement of MCS.There are 2 males and 5 females with an average age of(39.0±16.3)years(7~56 years)and an average weight of(57.6±19.9)kg(7~56 kg).The primary diseases of recipients are dilated cardiomyopathy(4 cases)severe viral myocarditis(2 cases)and ischemic cardiomyopathy(1 case).All of them develope acute decompensation of congestive heart failure.Before implanting MCS, two or more inotropic drugs are offered at maximal doses ages or IABP device, 6 cases required cardio-pulmonary resuscitation treatment and another patient for Heartcon assistance.All the patients bridge to heart transplatation.Results:Adjuvant therapy of MCS was offered for(20.0±11.5)d(7~34 d).Emergency HT is performed.Two post-HT deaths occurr due to multiple organ failure(1 case)and severe infection(1 case).The remainders recover smoothly during a follow-up period of(6~24 months).Conclusions:MCS device is recommended as a bridging too for HT recipients with refractory heart failure.It is imperative to improve clinical outcomes with MCS support before an onset of multiple organ dysfunction.Despite a perioperative mortality, long-term prognosis is generally satisfactory.

We reported a 54-year-old female patient with severe tricuspid regurgitation, who received mechanic valve in the mitral position 15 years ago. The patient’s Society of Thoracic Surgeons score was 8.27%, and was intolerant to open heart surgery, so she was recommended for transcatheter tricuspid valve replacement via right vena jugularis interna. The procedures were guided by echocardiography and X ray fluoroscopy on November 13, 2021, the prosthesis was implanted successfully, and the patient was recoved without any adverse events. After 1 month follow-up, her general condition was apparently improved.

Objective:To summarize the results and methods of surgical treatment for type A aortic dissection with small true lumen of the descending aorta.Methods:9 patients underwent surgical treatment for type A aortic dissection with small true lumen of the descending aorta between January 2017 and December 2019 were analyzed retrospectively. There were 7 males and 2 females, mean age of (41.6±9.2) years. Acute dissection were 2 cases, and chronic dissection were 7 cases. Preoerative computed tomography was used to diagnose the dissection and evaluate the true lumen of the descending aorta. This procedure was done in all patients via a median sternotomy under hypothermic CPB with SCP. 4-branched prosthetic graft was used to replace the ascending aorta and aortic arch. The procedures involving the descending aorta: Hybrid surgery using TEVAR. Distal intimal flap fenestration. Implanting the intraoperative stent-graft or prosthetic graft at false lumen for second-step operation.Results:There was no in-hospital mortality. Stroke, Spinal cord, visceral ischemia and lower limbs malfunction were not observed. Reintervention was not found in case with acute dissection during follow-up. One patient who reveived fenestration underwent TEVAR, others with chronic dissection underwent thoracoabdominal aortic replacement 3 months after surgery.Conclusion:Hybrid or staged procedures was a suitable alternative to patients with type A aortic dissection with small true lumen of the descending aorta.

Objective:To conduct a systematic review and Meta-analysis of the efficacy and safety of Apatinib and tegafur in colonic cancer.Methods:With "Apatinib" "Tegafur" "Colonic cancer" as keywords, PubMed, Embase, Web of Science, Cochrane Library, WanFang Data, VIP, CNKI and CBM were searched from inception to December 2020 to collect randomized controlled trail about treatment for colonic cancer with Apatinib and Tegafur. Evaluated the portion remission and stable duration and progression-free survival. Meta-analysis was performed by using RevMan 5.3 software.Results:Meta-analysis showed that in colonic cancer patients, the portion remission and stable duration, tumor progression of Apatinib were not inferior to those of Tegafur ( RR=1.10, 95% CI: 0.71-1.71, P=0.640; RR=0.51, 95% CI: 0.28-1.32, P=0.205). But for progression-free survival, Apatinib was superior to Tegafur in overall patients( SMD=0.90, 95% CI: 0.42-1.37, P<0.000 1). Conclusion:In the treatment of colon cancer, compared with Tegafur, Apatinib can effectively improve the progression-free survival and has better overall survival.

Objective: To examine the results of surgical treatment for endograft infection after thoracic endovascular aortic repair (TEAVR). Methods: Clinical data of 7 patients underwent surgical treatment for endograft infection after TEAVR at Department of Cardiothoracic Surgery, Changhai Hospital, the Navy Medical University between January 2016 and December 2018 were analyzed retrospectively. There were 6 males and 1 female, aging (51.5±16.7) years (range: 25 to 68 years). The origin of the aortic disease was descending aortic aneurysm in 5 cases, and Stanford B aortic dissection in 2 cases. Abdominal aorta below the level of the diaphragm was not involved in all patients. Two patients received "chimney technology" for left subclavian artery procedures. Time to infection was 5(3) months (M(Q_R)) (range: 1 to 24 months). Aortic endograft infection was diagnosed with a combination of microbiology (positive blood cultures, except one with mycotic), radiological evidence and clinical evidence of sepsis. Two patients suffered from aorto-esophageal fistula received emergency surgery, others were treated with elective surgery. Extra-anatomic prosthetic graft bypass was used for reconstruction of aorta, infected endogarft and aorta was removed, sac drainage was performed. Aorto-esophageal fistula was procedured according to the degree of lesions. All patients received antibiotics with specialist advice for 6 to 8 weeks. Results: One patient died due to septic shock. In the follow-time (range: 6 to 24 months), 1 patient suffered from thoracic infection in 3 months after surgery, an other patient got iliac abscess after a month. Conclusions Endograft infection after TEAVR is high risk but may be curative. Appropriate selection of patients for infected endograft explantation could get a satisfied results.

Objective    To study the clinical characteristics, therapy strategies and the outcomes of female patients with acute aortic dissection during late pregnancy and puerperal period. Methods    We retrospectively analyzed the clinical data of 7 patients with acute aortic dissection during late pregnancy and puerperal period in Shanghai Changhai Hospital between August 2012 and June 2017. Five of the 7 patients were late stage pregnancy, 2 were puerperal period (1 at the postpartum night, 1 in 18 days after delivery). There were 6 patients of Stanford type A aortic dissection (85.7%), and 1 patient of type B aortic dissection (14.3%). The age of the patients ranged from 26 to 34 (30.8±3.1) years. Cardiac ultrasonography of patients with type A showed that the maximum diameter of the ascending aortas was 4.2–5.7 (4.7±0.6) cm, of which 2 patients were aneurysm of aortic sinus, 3 patients were with Marfan syndrome. Bentall procedure was conducted in 1 patient, Bentall+Sun’s surgery in 2 patients, ascending aorta replacement+Sun’s+coronary artery bypass grafting surgery in 1 patient, aortic root remodeling+ascending aorta replacement+Sun’s surgery in 2 patients. One patient with Stanford type B acute aortic dissection was performed with thoracic endovascular aortic repair (TEVAR) after cesarean section. Results     Aortic blocking time ranged from 51 to 129 (85.5±22.9) min.  Cardiopulmonary bypass time was 75–196 (159.0±44.0) min. Moderate hypothermic circulation arrest with selective cerebral perfusion time was 20–30 (23.8±3.5) min. All maternal and fetuses survived. The infant whose mother received aortic repair in early stage and then received cesarean section was diagnosed with cerebral palsy. Maternal and fetuses were followed up for 9 months to 4 years. During the follow up period, all the fetuses grew well except the cerebral palsy one, and all maternal recovered well. The patient who received aortic repair in the early stage, had a sigmoid rupture during cesarean section and was treated with sigmoid colostomy. Another patient with Stanford type A dissection was diagnosed as left renal vein entrapment syndrome after 2 years. Conclusion    Type A aortic dissection is more common in late pregnancy and puerperal patients. And Marfan syndrome is a high-risk factor for acute aortic dissection in pregnancy women. Early and appropriate surgical treatment strategy based on the type of aortic dissection and gestational age are the key points to achieve good outcomes both for maternal and fetus.
