Objective To evaluate the outcome of endovascular treatment with coarctation of aorta (CoA).Methods Between November 2007 and March 2012,11 patients,including 8 male and 3 female from 17 to 43 years old,with native CoA who were diagnosed by computed tomography angiography accepted the endovascular treatment.The arterial pressure difference between the femoral artery and the narrow segment was measured during the operation,and the stent was released by expanding the balloon.Results Endovascular treatment were successful in all cases without any major adverse events.Significant reduction of systohc blood pressure was observed from (64.09 ± 7.81) mmHg (1 mmHg =0.133 kPa) to (11.18 ± 3.37) mmHg.The mean CoA diameter pre-stent (4.000 ± 0.775) mm,post-stent (17.090 ± 2.427) mm.1 patient associated with patent ductus arteriosis had no persistent left-to-right shunt after covered stent implantation.The follow up range was 33 months.1 patient in simple balloon was retreatment by surgical because of restenosis.And no retraction was observed of 10 patients after stent implantation.Conclusion The early and midterm result of endovascular treatment with CoA is satisfactory,and longer follow-up is needed for its longterm outcomes.

Objective To explore the appropriately operative chance , method, and perioperative management of coronary arterybypass grafting (CABG) in the patients with severe left main artery (LMA) stenosis with three-vessel-disease.Methods A total of296 patients with severe LMA stenosis with three-vessel-disease who underwent CABG surgery was analyzed retrospectively from 2003through 2013.Of them, 276 patients underwent conventional coronary artery bypass surgery on pump ( CCABG)and 20 patients underwentoff-pump CABG( OPCAB); 172 Patients was over 60 years old (58.1%)and 246 patients (83.10%) had concomitant diseasesincluding valve lesion, hypertension, diabetes, myocardial infarction, left ventricular aneurysm with septal defect , stroke, renal failure,and cancer.Left internal mammary artery use was in 281 patients (95.1%); and 32 patients were implanted intra-aortic ballonpump(IABP) perioperatively.Results There were 7 cases(2.36 %) death of postoperative low cardiac output , ventricular fibrillation,cerebral infarction, renal failure, and multiple organ failure, respectively.Postoperative complications were low cardiac output ,respiratory failure , ventricular fibrillation, cereboembolism, cardiac tampomade, renal failure, stroke, and multiple organ failure.Afterfollow-up 2 to 84 months, there was 3 death in which 2 death of cardiac factors.Conclusions CCABG was a safe and effectivemethod in patients with severe LMA stenosis with severe three -vessel-disease.Preoperative insertion of IABP can certainly avoid the po -tential operative risk factor and significantly decrease the mortality and morbidity .

OBJECTIVEBody plethysmography is a typical method to measure functional residual capacity (FRC) and airway resistance (Raw). The aim of the study was to test the feasibility of measuring lung function with the body plethysmography in young children with acute lower respiratory tract infection (ALRI) by evaluating changes and prognosis of lung function for infants with ALRI with or without wheezing via body plethysmograph.

METHODPulmonary function tests (PFTs) were performed by using body plethysmography in 444 children with ALRI, aged 1-36 months, to assess their tidal breathing parameters such as ratio of time to peak tidal expiratory flow to total expiratory time (TPTEF/TE), ratio of volume to peak tidal expiratory flow to total expiratory volume (VPTEF/VE), plethysmographic functional residual capacity (FRCP), FRCP per kilogram (FRCP/kg), specific effective airway resistance (sReff), effective airway resistance (Reff), Reff per kilogram (Reff/kg), etc. According to whether there was wheezing or not, children who had ALRI with wheezing were classified as Group-W, or without wheezing as Group-N. Changes or correlations of tidal breathing parameters and plethysmographic parameters were compared.One hundred and three contemporaneous healthy controls aged 1-36 months underwent the same tests for comparison. And 36 wheezing children accepted PFTs at follow-up in recovery phase.

RESULTMean values of TPTEF/TE in Group-W,Group-N and the Control respectively were (20.5 ± 6.7)%,(22.8 ± 6.5)%,(34.6 ± 5.0)% (F = 110.500, P < 0.001), while VPTEF/VE respectively were (23.0 ± 6.3)%,(25.2 ± 6.8)%,(34.5 ± 4.2)% (F = 107.800, P < 0.001). Compared to the Control,Group-W and Group-N had significantly higher values of FRCP (226 vs. 176 vs. 172 ml, χ(2) = 64.870, P < 0.001), FRCP/kg(24.40 vs.17.80 vs.17.60 ml/kg,χ(2) = 68.890, P < 0.001), sReff(1.00 vs. 0.52 vs. 0.46 kPa·s,χ(2) = 75.240, P < 0.001), Reff (3.90 vs.2.74 vs.2.20 kPa·s/L, χ(2) = 36.480, P < 0.001) and Reff/kg [0.42 vs. 0.29 vs.0.22 kPa·s/(L·kg), χ(2) = 29.460, P < 0.001]. Although 25 (12.8%) wheezing children with ALRI had normal values of tidal breathing parameters, they already had increased FRCP, FRCP /kg, sReff, Reff and Reff/kg (t = 2.221, 1.997, 2.502, 2.587, 2.539, all P < 0.05). Values of FRCP and Reff in infants caught ALRI were inversely correlated to that of TPTEF/TE and VPTEF/VE (P < 0.05); 36 children with wheezing who accepted PFTs at follow-up had shown significant decline in the specific parameters of plethysmography such as FRCP, FRCP/kg, sReff, Reff and Reff/kg (Z = -1.999, -2.195, -2.038, -1.823, -2.054, all P < 0.05), while no improvement in the main parameters of tidal breathing such as TPTEF/TE.

CONCLUSIONMeasuring lung function with the body plethysmography in young children with ALRI is feasible. FRC and Raw, as special lung function testing parameters of body plethysmography, were sensitive indicators reflecting impairment of lung function in infants with ALRI (especially for children caught ALRI with wheezing) and shows significant correlation with parameters from lung function testing via tidal breathing. Therefore plethysmography is worthy of clinical promotion.

Objective To explore the safety and efficiency of sequential operation of Tirelizumab combined with chemotherapy in neoadjuvant therapy for locally advanced esophageal cancer.Methods A retrospective analysis was conducted on 60 patients with locally advanced esophageal cancer admitted to Renmin Hospital of Wuhan University from August 2018 to June 2022.The immunotherapy combined with chemotherapy sequential surgery patients were selected as the observation group(29 cases)and the chemotherapy sequential surgery patients were selected as the control group(31 cases)according to the treatment method.The study aimed to analyze whether there were differences in efficacy and safety between the two groups.Results There are 28 patients with R0 resection in the observation group,and 14 case reached ORR.In the control group,29 cases were resected with R0,and 7 cases reached ORR.The proportion of ORR patients in the observation group was significantly higher than that in the control group,which was statistically significant(P＜0.05).There were 9 patients with pCR in the observation group and 2 patients with pCR in the control group,and the proportion of pCR patients in the two groups was significantly different(P＜0.05).There were no significant differences between the two groups for preoperative and postoperative adverse events.Conclusion Immune checkpoint inhibitors combined with chemotherapy sequential surgery are safe and reliable in patients with locally advanced esophageal cancer,with significant short-term efficacy,and long-term efficacy remains to be observed.

Objective To summarize the clinical experience in the treatment of postoperative upper gastrointestinal cancer of esophageal cancer.Methods The clinical data of 16 patients with postoperative upper gastrointestinal malignancies treated in our hospital from January 2018 to June 2022 were retrospectively analyzed.Results All the 16 patients successfully completed the operation,and no perioperative death occurred.The cumulative length of hospitalization was 18-38 days.After operation,2 cases of pulmonary infection,1 case of respiratory failure,and 1 case of cervical anastomotic fistula were cured after conservative treatment.All patients could eat normally during postoperative follow-up,and no tumor recurrence and metastasis was found.Conclusion For patients with recurrent upper gastrointestinal cancer after esophageal cancer surgery,if the lesion is relatively limited,surgical treatment is reliable and an optional treatment plan.

OBJECTIVEThis study evaluates the biological effects of naringin (NAR) joint bone morphogenetic protein (BMP)-2 on the proliferation, alkaline phosphatase (ALP) activity, and expression of osteoblastogenic genes, such as Runt-related transcription factor 2 (Runx2), collagen Ⅰ (ColⅠ), ALP, and osteocalcin (OCN) of pre-osteoblasts.

METHODSThree different NAR concentrations (10, 100, and 1 000 μmol·L⁻¹) were applied, alone or combined with BMP-2(50 ng·mL⁻¹), to restore the osteoblastogenesis of pre-osteoblasts (MC3T3-E1 cell line). Cell numbers (proliferation) were evaluated at first, fourth, and seventh days by Alamar blue assay. ALP activity and the expression of osteoblastogenic genes, such as Runx2, ColⅠ, ALP, and OCN were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR) at fourth and seventh day.

RESULTSStimulation by NAR alone and in combination with BMP-2 for 1 day and 4 days could promote cell proliferation, which peaked at a concentration of 100 μmol·L⁻¹ NAR combined with BMP-2 could promote cell proliferation significantly (P<0.05). Stimulation by NAR alone and in combination with BMP-2 for 4 and 7 days could promote ALP activity and bone-related gene(ALP, OCN, Runx2, ColⅠ) expression. ALP expression was significantly promoted after stimulation of 100 μmol·L⁻¹ NAR and BMP-2 (P<0.05).

CONCLUSIONSNAR exhibits promising potential for improving MC3T3-E1 proliferation and differentiation, and appropriate concentrations of NAR and BMP-2 show synergistic effect.

OBJECTIVETo investigate the clinical epidemiologic characteristics and analyze risk factors for acute respiratory syncytial virus (RSV) infection in hospitalized infants with acute lower respiratory tract infection (ALRI).

METHODALRI infants admitted to Children's Hospital of Fudan University from March 1st, 2011 to February 29th, 2012, were enrolled in this study. Patient information included demographic characteristics, feeding history, family status, clinical presentation, accessory examination, treatment and prognosis. According to the etiology of ALRI infants, we compared the seasonal distribution, demographic characteristics, household characteristics and underlying diseases between RSV-positive patients and RSV-negative patients. Univariate and multiple Logistic regression analyses were used to determine factors that were associated with risk of RSV infection.

RESULTAmong 1 726 ALRI infants, there were 913 RSV-positive infants (52.9%). The occurrence of RSV infection had a seasonal variation, with a peak in winter (59.1%). The median (P25, P75) age of RSV infants was 64 (21-155) days. The gestational age (GA) and body weight (BW) was (37.5 ± 2.4) weeks and (3.07 ± 0.66) kg, respectively. The male/female ratio among these was 1.9: 1. RSV infection was more popular among infants in the families with smoking members, crowded living conditions, history of atopic mother. Differences of the proportion of patients with underlying disease between RSV-positive and negative groups were statistically significant (59.4% vs. 54.2%, P < 0.05). Univariate logistic regression demonstrated that factors increasing the risk of RSV infection were: GA<37 weeks (OR = 1.346, 95%CI: 1.037-1.748), birth weight <2 500 g (OR = 1.447, 95%CI: 1.103-1.898), underlying diseases (OR = 1.232, 95%CI: 1.018-1.492), underlying CHD (OR = 1.391, 95%CI: 1.120-1.728), environmental tobacco smoke exposure (OR = 1.254, 95%CI: 1.035-1.519), mother with atopic diseases (OR = 1.827, 95%CI: 1.296-2.573), crowded house with four or more than four family members (OR = 1.232, 95%CI: 1.013-1.498), autumn or winter infection (OR = 1.351, 95%CI: 1.024-1.783; OR = 1.713, 95%CI: 1.332-2.204). Multivariate logistic regression determined the factors increasing the risk of RSV infection were: underlying CHD (OR = 1.298, 95%CI: 1.002-1.681), mother with atopic diseases (OR = 1.766, 95%CI: 1.237-2.520), autumn or winter infection (OR = 1.481, 95%CI: 1.105-1.985; OR = 1.766, 95%CI: 1.358-2.296).

CONCLUSIONThe prevalence of RSV infection was the highest in winter, while preterm and low birth weight infants were more susceptible. Underlying diseases were found in 59.4% cases, CHD was the most common one. The factors increasing the risk of RSV infection were: CHD, mother with atopic diseases, autumn or winter infections.
