Objective To study the distribution characteristics of TCM constitutions in the middle-aged and elderly Mongolian population undergoing physical examinations in Inner Mongolia;To analyze the correlation with related risk factors.Methods Health information and related risk factors(including BMI index,lifestyle habits,dietary habits and exercise status)of middle-aged and elderly Mongolian people who visited the physical examination departments of Inner Mongolia Autonomous Region Traditional Chinese Medicine Hospital and Tongliao City Traditional Chinese Medicine Hospital from March 2024 to April 2024 were collected.A total of 213 Mongolian people were surveyed,including 65 people who have lived in Hohhot for more than 2 years and 148 people who have lived in Tongliao for more than 2 years.Through investigation,research and analysis,the distribution characteristics of TCM constitutions in the population and its correlation with related risk factors were observed.Results Constitution distribution:101 people(47.41%)had a moderate constitution.Among the biased constitutions,the phlegm dampness constitution had the highest number of people(64 people,30.05%),with the blood deficiency constitution having the lowest number of people(2 people,0.94%).In the investigation of related risk factors,there was a significant correlation(P<0.01)between phlegm dampness and dietary habits and reduced exercise volume.Moreover,individuals with this constitution tend to have good sleep,reduced physical activity,faster eating and a diet primarily consisting of high-calorie foods(P<0.05).Conclusion The TCM constitution of the Mongolian population in Inner Mongolia is mostly composed of moderate constitution,while the biased constitution is mostly composed of phlegm dampness constitution,which is mainly related to dietary habits and reduced exercise volume.

Objective To compare early outcomes of the minimally invasive aortic valve surgery (MIAVS) through right parasternal mini-thoracotomy with conventional mitral valve surgery (AVS),and evaluate feasibility and safety of MIAVS.Methods From January 2017 to December 2017,60 patients undergoing elective AVS in Nanjing First Hospital were prospectively enrolled in this study.There were 32 male and 28 female patients with their age of 28-72 (46.5 ± 10.2)years.Using a random number table,all the patients were randomly divided into a port-access MIAVS group (MIAVS group,n =20) and a conventional AVS group (conventional group,n =60).MIAVS group patients received port-access cardiopulmonary bypass (CPB) establishment via femoral artery,femoral vein and right internal jugular vein cannulation through right the 3rd in tercostal space with 5-6 cm right parasternal incision in length.Special MIAVS operative instruments were used for mitral valve repair or replacement.Conventional group patients received mitral valve repair or replacement under conventional CPB through median sternotomy.Perioperative clinical data,morbidity and mortality were compared between the 2 groups.Results There was no death in-hospital or shortly after discharge in this study.CPB time [(106.0 ± 21.0) minutes vs (73.0 ± 15.0) minutes] and aortic cross-clamping time [(78.0 ± 10.0) minutes vs (47.0 ± 7.0) minutes] of MIAVS group were significantly longer than those of conventional group (P ≤ 0.05).Postoperative mechanical ventilation time [(7.0 ±4.2) hours vs (10.2 ±5.3)hours],length of intensive care unit (ICU) stay [(19.0 ± 4.0) hours vs (27.5 ± 8.0) hours] and postoperative hospital stay [(8.5 ± 2.5) days vs (13.0 ± 3.0) days] of MIAVS group were significantly shorter than those of conventional group (P ≤ 0.05).Chest drainage volume within postoperative 12 hours [(100.0 ±40.0)ml vs (410.0 ±80.0)ml] and the percentage of patients receiving blood transfusion (15.0％ vs 55.0％) of MIAVS group were significantly lower than those of conventional group (P ≤0.05).Patients were followed up for 1-12 months,and the follow-up rate was 96.7％.There was no statistical difference in postoperative morbidity or mortality between the 2 groups (P ＞ 0.05).Conclusions Minimally invasive aortic valve surgery through right right parasternal mini-thoracotomy is a safe and feasible procedure for surgical treatment of mitral valve diseases.MIAVS can achieve similar clinical outcomes as conventional AVS,with more quickly recovery and less blood transfusion,and is a good alternative to conventional AVS.

Objective: To summarize the experience of reoperations on patients who had late complications related to previous aortic surgery for Stanford type A dissection. Methods: From August 2008 to October 2016, 14 patients (10 male and 4 female patients) who underwent previous cardiac surgery for Stanford type A aortic dissection accepted reoperations on the late complications at Department of Thoracic and Cardiovascular Surgery, Nanjing Hospital Affiliated to Nanjing Medical University. The range of age was from 41 to 76 years, the mean age was (57±12) years. In these patients, first time operations were ascending aorta replacement procedure in 3 patients, ascending aorta combined with partial aortic arch replacement in 4 patients, aortic root replacement (Bentall) associated with Marfan syndrome in 3 patients, aortic valve combined with ascending aorta replacement (Wheat) in 1 patient, ascending aorta combined with Sun′s procedure in 1 patient, Wheat combined with Sun′s procedure in 1 patient, Bentall combined with Sun′s procedure in 1 patient. The interval between two operations averaged 0.3 to 10.0 years with a mean of (4.8±3.1) years. The reasons for reoperations included part anastomotic split, aortic valve insufficiency, false aneurysm formation, enlargement of remant aortal and false cavity. The selection of reoperation included anastomotic repair, aortic valve replacement, total arch replacement and Sun′s procedure. Results: Of the 14 patients, the cardiopulmonary bypass times were 107 to 409 minutes with a mean of (204±51) minutes, cross clamp times were 60 to 212 minutes with a mean of (108±35) minutes, selective cerebral perfusion times were 16 to 38 minutes with a mean of (21±11) minutes. All patients survived from the operation, one patient died from severe pulmonary infection 50 days after operation. Three patients had postoperative complications, including acute renal failure of 2 patients and pulmonary infection of 1 patient, and these patients were recovered after treatment. Thirteen patients were finally recovered from hospital. The patients were followed up for 16 to 45 months, and no aortic rupture, paraplegia and death were observed in the follow-up. Conclusions Patients for residual aortic dissection after initial operations on Stanford type A aortic dissection should be attached great importance and always need emergency surgery, but the technique is demanding and risk is great for surgeons and patients, which need enough specification and accurate on aortic operation. More importantly, the Sun′s procedure also should be performed on the treatment of residual aortic dissection or distal arch expansion, and obtains the short- and long-term results in the future.

Objective    To analyze the clinical effect of partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection. Methods    From January 2010 to December 2015, 30 patients (25 males, 5 females) underwent partial aortic root remodeling for root reconstruction on Stanford type A aortic dissection with involvement of aortic root. The range of age was from 27 to 72 years, and the mean age was 51.2±8.0 years. The proximal aortic dissection received partial aortic root remodeling, and the operation procedures included partial aortic root remodeling+ascending aortic replacement in 9 patients, partial aortic root remodeling+ascending aortic replacement+hemi-arch replacement in 6 patients, partial aortic root remodeling+ascending aortic replacement+Sun's procedure in 15 patients. The patients were followed up for 10 to 60 months with a mean of 37.9±3.2 months. Preoperative and postoperative degrees of aortic regurgitation were compared. Results    All patients survived from the operation, and one patient died from severe pulmonary infection 15 days after operation. The overall survival rate was 96.7% (29/30). One patient died during the follow-up. Two patients underwent aortic valve replacement in the 12th and 15th postoperative month respectively because of severe aortic regurgitation (AI). Up to the last follow-up, trivial or no aortic regurgitation was demonstrated in 24 patients, but mild aortic regurgitation occurred in 2 patients. Conclusion    The surgical treatment for aortic root pathology due to Stanford type A aortic dissection is challenging, and partial aortic root remodeling operations could restore valve durability and function, and obtains the early- and mid-term results.
