ABSTRACT

Objective:To observe the effect of Dingkundan in adjuvant treatment of clinical symptoms, quality of life, immune function and prognosis of patients with radiotherapy and chemotherapy after endometrial carcinoma (EC) operation. Method:Patients were divided into control group (82 cases) and observation group (86 cases) according to random number table. A total of 75 patients in control group completed the study (4 patients fell off or lose visit, and 3 patients were eliminated), while 77 patients in observation group completed the study (5 patients fell off or lose visit, and 4 patients were deleted). After operation, patients got brachytherapy, external pelvic irradiation and chemotherapy. Patients in control group got Bazhenwan, 1 pill/time, 2 times/day, and those in observation group got Dingkundan, 7 g/time, 2 times/day. The course of treatment lasted for 4 months, and long-time follow-up data was recorded. Before treatment, and at the second and fourth month after treatment, deficiency of Qi and blood was scored. Toxic reactions after radiotherapy and chemotherapy were recorded, and incidence rate of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level were compared. And levels of T lymphocyte subsets (CD3<sup>+</sup>, CD4<sup>+</sup>, CD8<sup>+</sup> and CD4<sup>+</sup>/CD8<sup>+</sup>) were detected, European collaborative quality of life Cancer Core Scale (EORTC QLQ-C30) was evaluated, and expressions of pce125 (CA125), epididymis protein 4 (HE4), Dickkopf-related protein-1 (DKK1), vascular endothelial growth factor (VEGF), matrix metalloproteinase-9 (MMP-9) and transforming growth factor-<italic>β</italic><sub>1</sub> (TGF-<italic>β</italic><sub>1</sub>) were tested before and after treatment. The follow-up was made for every three months, and the progression (recurrence/metastasis) of patients was recorded. Result:Scores of deficiency of Qi and blood in observation group were lower than those in control group at the second and fourth week after treatment (<italic>P</italic><0.01). Incidence rates of acute and advanced radiation injury of bladder and rectum and toxicity of chemotherapeutic drugs at grade 3 or above grade 3 level and incidence rates of bone marrow suppression, gastrointestinal toxicity, neurotoxicity were lower than those in control group (<italic>P</italic><0.05). Five functional dimensions and overall quality of life score based on EORTC and QLQ-C30 in observation group were higher than those in control group (<italic>P</italic><0.01), and scores of three symptom dimensions were lower than those in control group (<italic>P</italic><0.01). Levels of CD3<sup>+</sup>, CD4<sup>+</sup> and CD4<sup>+</sup>/CD8<sup>+</sup> were higher than those in the control group (<italic>P</italic><0.01), and CD8<sup>+</sup> was lower than those in the control group (<italic>P</italic><0.01). Levels of CA125, HE4, DKK1, VEGF, MMP-9 and TGF-<italic>β</italic><sub>1</sub> were lower than those in the control group (<italic>P</italic><0.01). The disease progression rate in observation group was 18.18% (14/77), which was lower than 33.33% (25/75) in control group (<italic>χ</italic><sup>2</sup>=4.572, <italic>P</italic><0.05). Conclusion:In adjuvant treatment of patients with radiotherapy and chemotherapy after EC operation, Dingkundan can reduce the symptoms of Qi and blood deficiency syndrome and side effects caused by radiotherapy and chemotherapy, improve the quality of life and immune function, inhibit the expression of tumor markers and tumor growth factor, delay the progression of tumor and improve the prognosis.

ABSTRACT

Objective To explore the cause and the treatment strategies of iliac limb occlusion after endovascular abdominal aortic aneurysm repair(EVAR). Methods The patients receiving EVAR in PUMC Hospital from January 2015 to December 2020 were retrospectively analyzed.Sixteen(2.7%)cases of iliac limb occlusion were identified,among which 6,9,and 1 cases underwent surgical bypass,endovascular or hybrid procedure,and conservative treatment,respectively. Results Fifteen cases were successfully treated.During the 10.6-month follow-up,2 cases receiving hybrid treatment underwent femoral-femoral bypass due to re-occlusion of the iliac limb. Conclusions Iliac limb occlusion mostly occurs in the acute phase after EVAR,and endovascular or hybrid treatment can be the first choice for iliac limb occlusion.It is suggested to focus on the risk factors for prevention.

ABSTRACT

Median arcuate ligament syndrome(MALS)is compression of the celiac trunk by the median arcuate ligament.Median arcuate ligament release is the corner stone for the surgical treatment of MALS.Open surgery,laparoscopic surgery,and robot-assisted surgery have been developed,among which laparoscopic surgery has been proposed as the preferred approach in view of its minimal trauma and short hospital stay.Auxiliary celiac plexus neurolysis could further alleviate the patient's discomfort.Moreover,vascular reconstitution is of vital importance in the case of persistent stenosis in the celiac artery despite of median arcuate ligament decompression.Vascular reconstruction has satisfactory long-term patency rate,while endovascular treatment is less invasive.This article aims to summarize the consensuses and advances and shed light on the surgical treatment of MALS.

ABSTRACT

Objective:To investigate the predictive value of 18F-fluorodeoxyglucose (FDG) PET/CT metabolic parameters for occult lymph node metastasis (OLM) in non-small cell lung cancer (NSCLC). Methods:A total of 183 patients (72 males, 111 females; age (61.5±8.4) years) who underwent 18F-FDG PET/CT and preoperatively diagnosed with clinical N0 stage (cN0) in Third Affiliated Hospital of Soochow University from January 2013 to December 2018 were retrospectively enrolled. All patients underwent anatomical pulmonary resection with systematic lymph node dissections within 3 weeks after 18F-FDG PET/CT examinations. According to the presence or absence of lymph node metastasis, patients were divided into OLM positive (OLM+ ) group and OLM negative (OLM-) group. Parameters of primary lesions, such as the maximum diameter (D max), tumor sites, morphological features, maximum standardized uptake value (SUV max), mean standardized uptake value (SUV mean), metabolic total volume (MTV), total lesion glycolysis (TLG), tumor SUV max to liver SUV mean (TLR max), tumor TLG to liver SUV mean (TLR TLG) were analyzed. Mann-Whitney U test and χ2 test were used to compare the parameters between groups. Multivariable logistic regression was used to analyze the independent risk factors for OLM. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic value of different parameters. Results:Among 183 patients, 25 (13.7%, 25/183) of them were diagnosed as OLM. In OLM+ group, 46 lymph nodes were pathologically positive for metastasis, including 15 N1 disease and 31 N2 disease. D max (2.9(2.3, 3.7) vs 2.3(1.7, 2.8) cm), lobulation ((76.0%(19/25) vs 37.3%(59/158)), SUV max (11.1(7.9, 17.7) vs 4.7(2.3, 9.2)), TLG (41.5(10.2, 91.1) vs 15.6(6.5, 23.8) ml), TLR max (4.7(3.5, 7.6) vs 2.1(0.9, 4.0)) and TLR TLG (18.1(5.0, 44.3) vs 6.1(3.0, 11.4) ml) of the primary lesions in OLM+ group were significantly higher than those in OLM-group ( z values: from -4.709 to -3.247, χ2=13.190, all P<0.05). Multivariable logistic regression analysis showed that TLR max (odds ratio ( OR)=15.145, 95% CI: 3.381-67.830, P<0.001) and D max ( OR=3.220, 95% CI: 1.192-8.701, P=0.021) were independent risk factors for OLM. TLR max yielded the highest area under curve (AUC; AUC=0.794) with the threshold of 3.12, and the sensitivity, specificity, accuracy, positive predictive value and negative predictive value for predicting OLM were 92.0%(23/25), 63.3%(100/158), 67.2%(123/183), 28.4%(23/81) and 98.0%(100/102), respectively. Conclusions:TLR max of tumor is the independent risk factor for OLM in NSCLC patients. TLR max can sensitively predict OLM preoperatively in patients with NSCLC.

ABSTRACT

To explore the optimal therapy time for the treatment of severe coronavirus disease 2019(COVID-19)by traditional Chinese medicine(TCM)and its influence on the therapeutic effect and prognosis. The clinical data,laboratory findings,and outcomes of 64 patients with severe COVID-19 treated with TCM and western medicine in Chongqing from January 20,2020, to March 11,2020 were retrospectively analyzed.Patients were divided into early intervention group[TCM was initiated within 3 days (including day 3) after the first diagnosis of severe type/critical type COVID-19]and late intervention group[TCM was initiated after 7 days (including day 7) after the first diagnosis of severe type /critical type COVID-19].The changes in clinical parameters during the course of disease were compared between the two groups. On day 14,the oxygenation index was 292.5(252.0,351.0)mmHg in the early intervention group,which was significantly higher than that in the late intervention group [246.0(170.0,292.5)mmHg](=0.005).The length of hospital stay [(18.56±1.11)d (24.87±1.64)d,=0.001],duration of ICU stay [(14.12±0.91)d (20.00±1.53)d,=0.000] and time to negativity [(16.77±1.04)d (22.48±1.66)d,=0.001] in the early intervention group were significantly shorter than those in the late intervention group.The intubation rate(7.3%)in the early intervention group was significantly lower than that in the late intervention group(30.4%)(=0.028). Early TCM therapy within three days after a diagnosis of severe COVID-19 can shorten the length of hospital stay,duration of ICU stay,and time to negativity and decrease intubation rate.

ABSTRACT

BACKGROUND@#MAVERIC (Mitral Valve Repair Clinical Trial) validates the safety and efficacy of the ARTO system. We here report the first two successful cases of utilizing the ARTO system in patients with symptomatic heart failure (HF) with functional mitral regurgitation (FMR) in Asia.@*METHODS@#Two patients, aged 70 and 63, had severe HF with FMR. Transesophageal echocardiography confirmed that the left ventricular ejection fractions were less than 50% with severe mitral regurgitation (MR) in both patients. Optimizing drug treatment could not mitigate their symptoms. Therefore, we used the ARTO system to repair the mitral valve for these patients on March 5 and 6, 2019, respectively.@*RESULTS@#Mitral valve repairs using the ARTO system were successfully performed under general anaesthesia for these two patients. MR was decreased immediately after the procedures in both patients. The 30-day and 3-month transthoracic echocardiography (TTE) revealed a moderate to severe MR in both patients, and the New York Heart Association (NYHA) scales were also partially improved.@*CONCLUSION@#The first two cases in Asia indicate that the ARTO system is feasible for patients with heart failure with FMR, and the patient selection appears to be crucial.

ABSTRACT

BACKGROUND@# Stent failure is more likely in the lipid rich and thrombus laden culprit lesions underlying ST-segment elevation myocardial infarction (STEMI). This study assessed the effectiveness of post-dilatation in primary percutaneous coronary intervention (pPCI) for acute STEMI.@*METHODS@# The multi-center POST-STEMI trial enrolled 41 consecutive STEMI patients with symptom onset <12 hours undergoing manual thrombus aspiration and Promus Element stent implantation. Patients were randomly assigned to control group (n=20) or post-dilatation group (n=21) in which a non-compliant balloon was inflated to >16 atm pressure. Strut apposition and coverage were evaluated by optical coherence tomography (OCT) after intracoronary verapamil administration via thrombus aspiration catheter, post pPCI and at 7-month follow-up. The primary endpoint was rate of incomplete strut apposition (ISA) at 7 months after pPCI.@*RESULTS@# There were similar baseline characteristics except for stent length (21.9 [SD 6.5] mm vs. 26.0 [SD 5.8] mm, respectively, P=0.03). In post-dilatation vs. control group, ISA rate was lower (2.5% vs. 4.5%, P=0.04) immediately after pPCI without affecting final TIMI flow 3 rate (95.2% vs. 95.0%, P>0.05) or corrected TIMI frame counts (22.6±9.4 vs. 22.0±9.7, P>0.05); and at 7-month follow-up (0.7% vs. 1.8%, P<0.0001), the primary study endpoint, with similar strut coverage (98.5% vs. 98.4%, P=0.63) and 1-year rate of major adverse cardiovascular events (MACE).@*CONCLUSION@# In STEMI patients, post-dilatation after stent implantation and thrombus aspiration improved strut apposition up to 7 months without affecting coronary blood flow or 1-year MACE rate. Larger and longer term studies are warranted to further assess safety (ClinicalTrials.gov identifi er: NCT02121223).

ABSTRACT

Objective:To analyze clinical features of aortoesphageal fistula (AEF) patients with massive upper gastrointestinal hemorrhage.Methods:Five AEF patients with massive upper gastrointestinal hemorrhage admitted in Peking Union Medical College Hospital from 2016 January 1st to 2019 December 31st. The clinical data, endoscopic findings, radiological manifestations, treatment and clinical outcomes were retrospectively analyzed.Results:Among 5 patients, 4 were males, 1 was female with an average age of (58±8) years old. The underlying conditions were atherosclerosis ( n=4), hypertension ( n=3), hyperlipidemia ( n=1); 2 cases had aortic aneurysm stent implantation and 1 case of rheumatic heart disease had valve replacement. All 5 patients were complicated with hematemesis and hypovolemic shock, and 4 cases had sentinel hemorrhage. Contrast-enhanced CT or CT angiography of the aorta showed thicken esophageal wall, local esophageal discontinuity, aortic aneurysm, gas around the aortic stent and contrast agent spilling over. The gastroscopy showed esophageal depression lesions, deep ulcers, mucosal erosion with bleeding. Conservative therapy and endoscopic hemostasis failed, 2 patients died without surgical intervention; 3 patients underwent emergency surgeries, 2 survived and 1 died perioperatively. Conclusions:Aortoesophageal fistula is in lack of specific clinical manifestations but is highly in mortality. Therefore CT and gastrocopic examination should be performed for suspected patients, early diagnosis and surgical treatment are the key to save patients′ lives.

ABSTRACT

Objective:To summarize the surgical treatment of malignant carotid body tumor (MCBT).Methods:A retrospective analysis of 14 MCBT patients admitted at our hospital from Mar 2005 to Nov 2019 was made, and the imaging data, surgical records, perioperative complications and follow-up data were collected.Results:There were 8 males and 6 females, with an average age of (40.8±11.3) years. 10 patients underwent surgical resection of CBT, with one case undergoing tumor enucleation only, nine cases underwent internal carotid artery reconstruction, and all patients underwent intraoperative lymph node biopsy.Tumors were completely removed in all 10 patients. No perioperative death or cerebral infarction occurred. The intraoperative blood loss was (955±658.5) ml. Four patients had permanent nerve injury after surgery. The follow-up time ranged 1-132 months. There were no cases of cerebral infarction or death, and the reconstructed graft remained patent. Apart from the 2 patients who developed tumor metastasis after surgery, other patients recovered uneventfully with no disease progression.Conclusions:Surgery is still the main treatment for MCBT, but MCBT is large and Shamblin class is more advanced. Therefore, complete tumor removal and reconstruction of the carotid arteries are difficult. Surgery should seek to completely remove the tumor and neck lymph node biopsy should be performed to determine the lymph node metastasis.

ABSTRACT

Objective:To detect the levels of cytokines in peripheral blood of patients with chronic immune thrombocytopenia (ITP) and analyze their significance in the clinical prognosis of children with chronic ITP.Methods:Thirty patients with chronic ITP who were treated in the Department of Pediatrics, the First Affiliated Hospital of Xinxiang Medical Univercity from October 2015 to October 2018 were followed and enrolled in the experimental group and 40 healthy children in the same hospital were enrolled in the healthy control group.The levels of interleukin-2(IL-2), interferon-γ(IFN-γ), tumor necrosis factor(TNF), interleukin-4(IL-4), interleukin-6(IL-6), interleukin-10(IL-10) and interleukin-17A(IL-17A) in the experimental group and the healthy control group were detected by flow cytometry (CBA). The relationship between cytokines and prognosis of children with chronic ITP were analyzed.Results:Thirty patients with ITP were enrolled. The expressions of IL-2 and IL-17A in the experimental group before treatment were (7.86±3.90) ng/L and (10.45±12.35) ng/L, while those of IL-2 and IL-17A in the healthy control group were (3.11±2.41) ng/L and (2.97±7.04) ng/L. The levels of IL-2 and IL-17A in the experimental group were significantly higher than those in the healthy control group, and the differences were statistically significant ( t=-7.123, -5.582, all P<0.01). The expressions of IL-4 and IL-10 in the experimental group before treatment were (0.38±0.25) ng/L and (1.80±1.25) ng/L, while those of IL-4 and IL-10 in the healthy control group were (3.08±0.26) ng/L and (4.55±3.44) ng/L. The levels of IL-4 and IL-10 in the experimental group were significantly lower than those in the healthy control group, and the differences were statistically significant ( t=8.400, 5.653, all P<0.01). The expressions of IL-6, TNF and IFN-γ in the experimental group before treatment were (7.30±9.16) ng/L, (4.85±7.60) ng/L and (7.68±20.41) ng/L, while those of IL-6, TNF and IFN-γ in the healthy control group were (5.44±4.18) ng/L, (1.97±0.37) ng/L, (4.81±17.71) ng/L. There was no significant difference between the two groups ( P>0.05), and no significant difference in the levels of cytokines between the patients with chronic ITP before and 12 months after treatment ( P>0.05). Conclusions:The changes of T lymphocyte related cytokines are closely related to the pathogenesis and development of chronic ITP in children. There may be persistent immune dysfunction in children with chronic ITP. Dynamic monitoring of cytokines IL-2, IL-4, IL-10, IL-17A, especially IL-17A, is helpful to judge the prognosis of ITP in children, and may be of guiding significance in evaluating clinical prognosis.

ABSTRACT

Oral anticoagulants play an important role in the prevention and treatment of thromboembolic diseases.Warfarin,a traditional oral anticoagulant,is limited in clinical use due to its limitations such as narrow therapeutic window and requirements on frequent monitoring and dose adjustment.Direct oral anticoagulants(DOACs)such as dabigatran,rivaroxaban,apixaban,and edoxaban are increasingly used to prevent and treat venous thrombosis or thrombus formation.However,recent studies have documented inter-individual variability in plasma drug levels of DOACs.This article summarizes the recent advances in the pharmacogenomics of DOACs.

ABSTRACT

Currently, the local transmission of coronavirus disease 2019 (COVID-19) has been effectively contained in China; however, the epidemic situation of this highly infectious disease is more and more serious outside of China. Importation of COVID-19 cases from other countries and territories is therefore becoming a new challenge for the control of COVID-19 in China. Malaria was once widely epidemic in China. Nevertheless, the local transmission of this parasitic disease has been interrupted in China since the launch of the national malaria elimination programme in 2010, and great successes have been achieved in the management of appropriately 3 thousand malaria cases imported from other countries and territories annually. Hereby, the epidemiological characteristics and current epidemic situation of COVID-19 in China were analyzed and compared with malaria. Based on the successful experiences from the management of overseas imported malaria in China, the strategy and countermeasures for COVID-19 control were proposed, so as to provide insights into the response to the importation of COVID-19 from other countries and territories and the consolidation of the control achievements in China.

ABSTRACT

Acupuncture has been widely used for treating diseases since the ancient days in China, but the mechanism by which acupuncture exerts such powerful roles is unclear. Epigenetics, including DNA methylation, histone modification, and post-transcriptional regulation of miRNAs, is the study of heritable changes in gene expression that do not include DNA sequence alterations. Epigenetics has become a new strategy for the basic and clinical research of acupuncture in the last decade. Some investigators have been trying to illustrate the mechanism of acupuncture from an epigenetics perspective, which has shed new lights on the mechanisms and applications of acupuncture. Moreover, the introduction of epigenetics into the regulatory mechanism in acupuncture treatment has provided more objective and scientific support for acupuncture theories and brought new opportunities for the improvement of acupuncture studies. In this paper, we reviewed the literatures that has demonstrated that acupuncture could directly or indirectly affect epigenetics, in order to highlight the progress of acupuncture studies correlated to epigenetic regulations. We do have to disclose that the current evidence in this review is not enough to cover all the complex interactions between multiple epigenetic modifications and their regulations. However, the up-to-date results can help us to better understand acupuncture's clinical applications and laboratory research.

ABSTRACT

Objective To explore the feasibility of Narcotrend index (NTI) for digital monitoring of light sedation depth in patients undergoing short-term mechanical ventilation after pancreaticoduodenectomy. Methods A prospective randomized controlled trial was conducted. Patients with mechanical ventilation for 12-48 hours after pancreaticoduodenectomy admitted to department of critical care medicine of the First Affiliated Hospital of Wannan Medical College from January 2016 to December 2018 were enrolled. They were randomly divided into two groups, and NTI and Richmond agitation-sedation score (RASS) were used to guide light sedation treatment respectively. The implementation effect of light sedation, duration of mechanical ventilation, dosage of sedative drugs, occurrence of adverse events (accidental extubation, delirium, cardiovascular events) and stress response [cortisol, epinephrine, norepinephrine, C-reactive protein (CRP)] were compared between the two groups. Results A total of 87 patients were enrolled in this study, of whom 45 received NTI-guided sedation assessment and 42 received RASS-guided sedation assessment. There were no significant differences in gender, age, body mass index (BMI), liver function classification, operation time, blood loss, conversion to laparotomy and acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score between the two groups. During sedation treatment, the light sedation compliance rate after light sedation, 2, 4, 6 hours and cumulative compliance period number (Dt) in NTI group were higher than those in RASS group [71.1% (32/45) vs. 50.0% (21/42), 80.0% (36/45) vs. 54.8% (23/42), 88.9% (40/45) vs. 59.5% (25/42), 83.9% (642/765) vs. 62.8% (475/756), all P < 0.05]. The dosage of dexmedetomidine in NTI group was higher than that in RASS group (μg·kg-1·h-1:0.60±0.10 vs. 0.54±0.12, P < 0.01), but more patients in RASS group receiveda larger dose of propofol to maintain sedation [ratio of use of propofol: 64.3% (27/42) vs. 37.8% (17/45), dose of propofol (mg/h): 47.82±7.31 vs. 30.83±10.35, both P < 0.05]. The sedation duration and duration of mechanical ventilation in NTI group were lower than those in RASS group (hours: 15.68±2.43 vs. 17.29±2.43, 16.27±2.42 vs. 18.25±2.04, both P < 0.01). There were no significant differences in hypertension, bradycardia, accidental extubation and delirium between the two groups during sedation treatment, but the incidence of hypotension in RASS group was higher than that in NTI group [35.7% (15/42) vs. 13.3% (6/45), P < 0.05]. Compared with RASS group, epinephrine, norepinephrine and the levels of CRP at treatment of 6 hours with light sedation and 2 hours after tracheal catheter removal in NTI group were decreased [epinephrine (pg/L): 138.35±18.60 vs. 157.50±19.91, 136.24±40.40 vs. 150.46±20.22; norepinephrine (pg/L): 347.34±45.46 vs. 393.75±49.77, 340.59±50.95 vs. 376.37±49.70; CRP (μg/L): 62.26±18.78 vs. 71.31±10.32, 53.30±14.47 vs. 64.26±14.69, all P < 0.05], and cortisol level 6 hours after treatment with light sedation was lower than that of RASS group (nmol/L: 327.03±41.04 vs. 358.12±70.01, P < 0.05). Conclusion The application of NTI monitoring to guide light sedation therapy for patients with short-term mechanical ventilation after pancreaticoduodenectomy can better achieve the goal of light sedation.

ABSTRACT

Mixed linked leukemia 4 (MLL4) is a specific methyltransferase of histone 3 position lysine 4 (H3K4). It is also one of the important members of COMPASS/Set1-like protein complex. Both MLL4 protein itself and its mediated H3K4 methylation modification can cause changes in chromatin structure and function, thus regulating gene transcription and expression. With the studies of MLL4 protein in recent years, the roles of MLL4 gene, MLL4 protein and protein complex in the development of tissues and organs, tumor diseases and other physiological and pathophysiological processes have been gradually revealed. In this paper, the research progress of MLL4 gene, MLL4 protein characteristics, biological function and its effect on disease were reviewed, in order to further understand the effect of histone methyltransferase on gene expression regulation, as well as its non-enzyme dependent function. This paper may provide new ideas for the prevention, diagnosis and treatment of related diseases.

ABSTRACT

BACKGROUND@#Current data is lacking about the progression of ascending aortic dilatation after transcatheter aortic valve replacement (TAVR) in aortic stenosis (AS) patients with bicuspid aortic valve (BAV) and tricuspid aortic valve (TAV). This study aims to assess the ascending aortic dilatation rate (mm/ year) after TAVR in patients with BAV versus TAV using a multidetector computed tomography (MDCT) follow-up and to determine the predictors of ascending aortic dilatation rate.@*METHODS@#Severe AS patients undergoing TAVR from March 2013 to March 2018 at our center with MDCT follow-ups were included. BAV and TAV were identified using baseline MDCT. Baseline and follow-up MDCT images were analyzed, and the diameters of ascending aorta were measured. Study end point is ascending aortic dilatation rate (mm/year). Furthermore, factors predicting ascending aortic dilatation rate were also investigated.@*RESULTS@#Two hundred and eight patients were included, comprised of 86 BAV and 122 TAV patients. Five, 4, 3, 2, and 1-year MDCT follow-ups were achieved in 7, 9, 30, 46, and 116 patients. The ascending aortic diameter was significantly increased after TAVR in both BAV group (43.7±4.4 mm vs. 44.0±4.5 mm; P<0.001) and TAV group (39.1±4.8 mm vs. 39.7±5.1 mm; P<0.001). However, no difference of ascending aortic dilatation rate was found between BAV and TAV group (0.2±0.8 mm/year vs. 0.3±0.8 mm/year, P=0.592). Multivariate linear regression revealed paravalvular leakage (PVL) grade was independently associated with ascending aortic dilatation rate in the whole population and BAV group, but not TAV group. No aortic events occurred during follow-ups.@*CONCLUSION@# Ascending aortic size continues to grow after TAVR in BAV patients, but the dilatation rate is mild and comparable to that of TAV patients. PVL grade is associated with ascending aortic dilatation rate in BAV patients post-TAVR.

ABSTRACT

During the past 70 years since the founding of New China, Chinese public health especially the prevention and control of infectious diseases have made remarkable achievements, which benefited from the vaccination. This study is to summarize the progress of immunization and vaccines, the achievements and contributions of vaccines including polio vaccine, hepatitis B vaccine, diphtheria, tetanus and acellular pertussis combined vaccine, measles vaccine and hepatitis A vaccine to the prevention and control of infectious diseases in China in the past 70 years and to review the research and development of innovative vaccines in China in recent years, which may provide clues for the development of the expanded programe on immunization in China in the future.
