ABSTRACT

Objectives: To construct a nomogram for prediction of intrahepatic cholangiocarcinoma (ICC) lymph node metastasis based on inflammation-related markers,and to conduct its clinical verification. Methods: Clinical and pathological data of 858 ICC patients who underwent radical resection were retrospectively collected at 10 domestic tertiary hospitals in China from January 2010 to December 2018. Among the 508 patients who underwent lymph node dissection,207 cases had complete variable clinical data for constructing the nomogram,including 84 males,123 females,109 patients≥60 years old,98 patients<60 years old and 69 patients were pathologically diagnosed with positive lymph nodes after surgery. Receiver operating characteristic curve was drawn to calculate the accuracy of preoperative imaging examinations to determine lymph node status,and the difference in overall survival time was compared by Log-rank test. Partial regression squares and statistically significant preoperative variables were screened by backward stepwise regression analysis. R software was applied to construct a nomogram,clinical decision curve and clinical influence curve,and Bootstrap method was used for internal verification. Moreover,retrospectively collecting clinical information of 107 ICC patients with intraoperative lymph node dissection admitted to 9 tertiary hospitals in China from January 2019 to June 2021 was for external verification to verify the accuracy of the nomogram. 80 patients with complete clinical data but without lymph node dissection were divided into lymph node metastasis high-risk group and low-risk group according to the score of the nomogram among the 858 patients. Log-rank test was used to compare the overall survival of patients with or without lymph node metastasis diagnosed by pathology. Results: The area under the curve of preoperative imaging examinations for lymph node status assessment of 440 patients was 0.615,with a false negative rate of 62.8% (113/180) and a false positive rate of 14.2% (37/260). The median survival time of 207 patients used to construct a nomogram with positive or negative postoperative pathological lymph node metastases was 18.5 months and 27.1 months,respectively (P<0.05). Five variables related to lymph node metastasis were screened out by backward stepwise regression analysis,which were combined calculi,neutrophil/lymphocyte ratio,albumin,liver capsule invasion and systemic immune inflammation index,according to which a nomogram was constructed with concordance index(C-index) of 0.737 (95%CI: 0.667 to 0.806). The C-index of external verification was 0.674 (95%CI:0.569 to 0.779). The calibration prediction curve was in good agreement with the reference curve. The results of the clinical decision curve showed that when the risk threshold of high lymph node metastasis in the nomogram was set to about 0.32,the maximum net benefit could be obtained by 0.11,and the cost/benefit ratio was 1∶2. The results of clinical influence curve showed that when the risk threshold of high lymph node metastasis in the nomogram was set to about 0.6,the probability of correctly predicting lymph node metastasis could reach more than 90%. There was no significant difference in overall survival time between patients with high/low risk of lymph node metastasis assessed by the nomogram and those with pathologically confirmed lymph node metastasis or without lymph node metastasis (Log-rank test:P=0.082 and 0.510,respectively). Conclusion: The prediction accuracy of preoperative nomogram for ICC lymph node metastasis based on inflammation-related markers is satisfactory,which can be used as a supplementary method for preoperative diagnosis of lymph node metastasis and is helpful for clinicians to make personalized decision of lymph node dissection for patients with ICC.

ABSTRACT

Pro-inflammatory macrophages play key regulatory role in the occurrence and development of rheumatoid arthritis (RA). In this study, we constructed a celastrol (Cel)-loaded polyamide-amine dendrimer (PAMAM) drug delivery system, which could target folate receptor and mitochondria. It could target inflammatory macrophages and realize chemo-photothermal synergistic therapy. Using PAMAM as the nano-carrier, folate receptor-targeting group folic acid (FA) and mitochondria-targeting group IR808 (also known as the photothermal agent) were conjugated with PAMAM through amide reaction, and then complexed with anti-inflammatory drug Cel to prepare the FA-PAMAM-IR808/Cel nanocomplex. In vitro characterization results showed that the drug loading efficiency of the nanocomplex was 50.90%, particle size was between 130 and 160 nm, average potential was between 1.0 and 3.5 mV, the drug release showed pH sensitivity, temperature reached to 42.5 ℃ after near-infrared (NIR) light irradiation for 10 min. In vitro cellular uptake experiments showed that the nanocomplex had obvious folate receptor-targeting and mitochondria-targeting ability. Following irradiation with NIR light, the cytotoxicity and cellular apoptosis enhanced. The secretion of pro-inflammatory factors tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6 and nitric oxide (NO) decreased in a concentration-dependent manner. This study provided insights for the development of novel anti-RA nanomedicines.

ABSTRACT

OBJECTIVES@#To study the correlation between 25-hydroxyvitamin D [25-(OH)D] and nephroblastoma in children and its value in assessing the prognosis of the disease.@*METHODS@#A total of 50 children with nephroblastoma who were admitted from January 2018 to December 2022 were included as the nephroblastoma group, and according to the postoperative pathological type, they were divided into a good prognosis group with 38 children and a poor prognosis group with 12 children. A total of 50 healthy children who underwent physical examination during the same period of time served as the healthy control group. The above groups were compared in terms of serum creatinine and 25-(OH)D level. A Spearman correlation analysis was used to investigate the correlation between serum 25-(OH)D level and therapeutic effect reaction. A multivariate logistic regression analysis was used to identify the risk factors affecting the prognosis of nephroblastoma in children.@*RESULTS@#The nephroblastoma group had significantly lower levels of serum creatinine and 25-(OH)D than the healthy control group (P<0.05). Compared with the good prognosis group, the poor prognosis group had a significantly larger tumor diameter, a significantly higher proportion of children with stage III-IV tumors, a significantly higher rate of tumor metastasis, and significantly lower serum levels of creatinine and 25-(OH)D (P<0.05). The Spearman correlation analysis showed that serum 25-(OH)D level was negatively correlated with therapeutic effect reaction (rs=-0.685, P<0.001). The multivariate logistic regression analysis showed that tumor diameter ≥10 cm, stage III-IV tumors, presence of tumor metastasis, and 25-(OH)D <19 ng/mL were closely associated with the poor prognosis of nephroblastoma in children (P<0.05). Serum 25-(OH)D level had an area under the curve of 0.805 (95%CI: 0.706-0.903, P<0.001) in evaluating the prognosis of nephroblastoma in children, with a Youden index of 0.512, a sensitivity of 0.938, and a specificity of 0.575 at the optimal cut-off value of 1.764 ng/mL.@*CONCLUSIONS@#There is a significant correlation between 25-(OH)D level and the prognosis of nephroblastoma in children, and 25-(OH)D can be used for prognosis prediction.

ABSTRACT

@#Objective    To evaluate the mid- and long-term outcomes of different surgical techniques for subaortic stenosis. Methods    The clinical data of 75 patients with subaortic stenosis who underwent surgery in our hospital from January 2008 to January 2018 were retrospectively analyzed, including 48 males and 27 females, with a median age of 72 (48, 132) months and mean weight of 21.35±15.82 kg. There were 40 (53.3%) patients combined with aortic regurgitation; 38 (50.7%) patients were the first time and 37 patients were the second time to receive the operation. According to the surgical techniques, 75 patients were divided into two groups: a group A (40 patients with simple subaortic membrane resection) and a group B (35 patients with subaortic membrane and muscle resection or modified Konno procedure). Results    Two (2.67%) patients died in hospital. There was one late death in the group B. The average preoperative and postoperative pressure gradient of all patients was 69.96±42.02 mm Hg and 7.44±12.45 mm Hg, respectively. All patients were followed up for 51 (12, 120) months. Pressure gradient at follow-up in the group A and the group B was 8.83±14.52 mm Hg and 5.86±9.53 mm Hg, respectively with no statistical difference (P=0.294). Four patients in the group A and 2 patients in the group B needed reintervention. However, there was no statistical difference in the long-term reintervention rate between the two groups (P=0.480). Conclusion    For the different degree of lesions in the left ventricular outflow tract, our management strategy is feasible. Although there is no statistical difference between two the groups in the long-term reintervention rate after simple valvular membrane resection, prolonged follow-up is necessary to examine the long-term outcomes of different surgical techniques.

ABSTRACT

To explore the mechanism of Suanzaoren Decoction in the treatment of insomnia from endogenous bile acid regulation, the present study investigated the hepatoprotective effect of Suanzaoren Decoction and the molecular changes of bile acids in the serum, liver, and ileum of insomnia model mice and Suanzaoren Decoction treated mice. The insomnia model in mice was established by the sleep deprivation method. After Suanzaoren Decoction(48.96 mg·kg~(-1)·d~(-1)) intervention by gavage for 7 days, the related indicators, such as water consumption, food intake, body weight, aspartate aminotransferase(AST), alanine transaminase(ALT), and total bile acid(TBA) were detected, and the pathological changes of the liver and ileum were observed. The molecular levels and distribution of 23 bile acids in the serum, liver, and ileum were analyzed by UPLC-MS/MS combined with principal component analysis(PCA) and partial least squares discriminant analysis(PLS-DA). The results showed that Suanzaoren Decoction could improve the decreased water consumption and food intake, weight loss, and increased AST and ALT in the model group, and effectively reverse the injury and inflammation in the liver and ileum. The bile acids in the liver of the insomnia model mice were in the stage of decompensation, and the bile acids in the serum, liver, and ileum of the mice decreased or increased. Suanzaoren Decoction could regulate the anomaly of some bile acids back to normal. Seven bile acids including glycoursodeoxycholic acid(GUDCA), glycodesoxycholic acid(GDCA), tauro-α-MCA(T-α-MCA), α-MCA, taurodeoxycholate(TDCA), T-β-MCA, and LCA were screened out as the main discriminant components by PLS-DA. It is concluded that Suanzaoren Decoction possesses the hepatoprotective effect and bile acids could serve as the biochemical indicators to evaluate the drug efficacy in the treatment of abnormal liver functions caused by insomnia. The mechanism of Suanzao-ren Decoction in soothing the liver, resolving depression, tranquilizing the mind, and improving sleep may be related to the molecular regulation of bile acid signals.

ABSTRACT

AIM: To observe the growth status and morphological changes of primary cultured bulbar conjunctival fibroblasts in different stages of conjunctivochalasis(CCH), and to determine the best passage time, so as to obtain stable and consistent CCH bulbar conjunctival fibroblasts.METHODS: CCH primary bulbar conjunctival fibroblasts were obtained by tissue block adhesion method. The fibroblasts were purified by trypsin differential digestion method. The growth status and morphological changes of fibroblasts in different periods were observed and recorded under inverted microscope. The fibroblasts were identified by immunofluorescence cytochemical staining.RESULTS: After 24h of CCH conjunctival tissue adherent to the wall, a small number of cells would be seen crawling out around the tissue blocks. The logarithmic phase of cell growth was from the 2-7d. The cells grew fast, with vigorously proliferation, clear outline, uniform distribution, increas in numbers and clear nuclei. From the 9-15d, the cell growth entered the plateau stage, the tissue blocks gradually aged and lost activity. The cells grew slowly, arranged loosely, the volume became larger, the shape became flat, and a large number of granular substances and vesicles were produced in the cytoplasm. Some cells fell off from the bottom of the culture bottle, and large gaps appeared between the cells. After subculture and purification, the size and morphology of fibroblasts were basically the same. Through cell identification, fibroblasts were long spindle, flat star or multi-process spindle, wide in the middle, oval nucleus, relatively small at both ends, with 2-3 slender processes of different lengths extending outward.CONCLUSION: Primary CCH bulbar conjunctival fibroblasts can be successfully obtained by tissue block adhesion method. When the cells grow to the 8d, they can be digested and passaged to obtain stable and consistent CCH conjunctival fibroblasts.

ABSTRACT

Objective:To investigate the efficiency, safety and complication of 0.7 mg dexamethasone sustained release agent (Ozurdex ?) vitreous cavity implantation for macular edema secondary to vitrectomy. Methods:A total of 15 patients (16 eyes) were included in this retrospective case series study. There were 7 males (8 eyes) and 8 females (8 eyes). Age ranged from 47 to 72 years old with an average age of (60.2±8.6)years. Among them, 8 cases were diabetic retinopathy (6 cases combined cataract surgery). 4 cases were silicone oil removal after retinal detachment surgery (all combined cataract surgery). 2 cases were epi-macular membrane (all combined with cataract surgery) and 1 case was vitreous hemorrhage (combined with cataract surgery). Ozurdex ? was implanted for macular edema after vitrectomy. The number of implantation was from 1 to 3 times (mean 1.67 times). The follow-up time was from 3 to 12 months, with an average of (7.33±3.50)months. Results:The best corrected visual acuity (BCVA) was improved in 10 cases (11 eyes), unchanged in 4 cases and decreased in 1 case within 3 months after Ozurdex ? implantation in the 15 cases (16 eyes). The macular edema was significantly improved in all cases. The central macular thickness (CMT) measured by optical coherence tomography (OCT) was from 350 to 1 370 γm before surgery with average thickness (621.60±235.48)γm, and the CMT postoperative was 118 to 556 γm with average thickness (269.87±118.14)γm, with statistically significant difference ( P<0.001). Cataract was not progressive after Ozurdex ? implantation. Macular edema was recurrent in 7 cases after first implantation and stable for additional 1-2 injections. Intraocular pressure elevation occurred in 3 cases 1 to 2 months after implantation with the highest intraocular pressure of 36 mmHg, which were controlled by local anti-glaucoma eye drops. Drugs entered into the anterior chamber in 2 cases and was taken out in 1 case. Conclusions:The efficiency of Ozurdex ? vitreous cavity implantation is definite and the complications are controllable, so it is a safe and effective method to treat macular edema after vitrectomy.

ABSTRACT

Objective:To investigate the clinical manifestations, characteristics of chest high-resolution computed tomography (HRCT), and prognosis of connective tissue disease (CTD) complicated with interstitial lung disease (ILD) in children.Methods:The clinical data of 53 children with CTD-ILD who were admitted to the Department of Rheumatology and Immunology, Affiliated Xi′an Children′s Hospital of Xi′an Jiaotong University from October 2013 to October 2019 were retrospectively analyzed, including clinical manifestations, blood gas analysis, chest HRCT and prognosis.Results:As for these 53 children with CTD-ILD, the ratio of male to female was 1.0∶1.4, the average age was (7.50±3.34) years, and the course of disease was 2.00 (0.85, 7.50) months.Among them, there were 25 cases (47.2%) of juvenile idiopathic arthritis (JIA), 15 cases (28.3%) of systemic lupus erythematosus (SLE), 11 cases of polymyositis / dermatomyositis (PM/DM) (20.7%), 1 case of overlap syndrome (OS) (1.9%), and 1 case of allergic granulomatosis with polyangiitis (AGPA) (1.9%). Although cough (39.6%) was the most common symptom of respiratory system in these children with CTD-ILD and fever(66.0%) was the most common symptom in the systemic features.Blood gas analysis appeared abnormal in 17 cases, including 10 cases of hypoxemia (18.9%) and 7 cases of type Ⅰ respiratory failure (13.2%). HRCT chest showed ground glass shadow, strip shadow, subpleural spot shadow, grid shadow, pleural thickening, consolidation shadow, nodular shadow and cystic low-density shadow, with the proportion of 52.8%, 26.4%, 22.6%, 18.9%, 11.3%, 7.5%, 1.9% and 1.9%, respectively; nonspecific interstitial pneumonia (NSIP)(39.6%) was the most common type of imaging classification.After the combined treatment with glucocorticoids, immunosuppressive agents and biological agents, HRCT chest showed remarkably improvement in 36 cases (67.9%), while no change in 8 cases (15.1%). A total of 75.0%(33 cases) of 44 cases were infected in the course of combined treatment.In addition, 9 cases (17.0%) died from acute respiratory distress syndrome (ARDS), among which 4 cases exacerbated to rapid progressive luge disease and 5 cases aggravated secondary ARDS due to infection.Conclusions:Only a small number of children with CTD-ILD have respiratory symptoms and signs.HRCT chest contributes to the early diagnosis of CTD-ILD, and its imaging manifestations are diverse.Blood gas analysis and HRCT chest play an important role in the disease evaluation and treatment planning.Moreover, it is the direction for further research to develop effective methods to prevent and control secondary infection so as to improve the survival rate and reduce the mortality rate during the active treatment of primary diseases.

ABSTRACT

Objective:To investigate the efficacy and safety of DOS regimen in adjuvant chemotherapy after D2 radical resection for advanced gastric adenocarcinoma.Methods:The clinical data of 130 patients who received adjuvant chemotherapy after D2 radical resection for advanced gastric adenocarcinoma in Jincheng People's Hospital from January 2017 to January 2019 were retrospectively analyzed. According to treatment regimens, the patients were divided into DOS regimen chemotherapy group (DOS group, 63 cases) and SOX (oxaliplatin, S-1) regimen chemotherapy group (SOX group, 67 cases). The short-term efficacy and adverse reactions of the two groups were compared.Results:Due to the irregular treatment time, 2 cases in each group were removed. Finally, there were 61 cases in DOS group and 65 cases in SOX group. The 1-, 2- and 3-year disease-free survival (DFS) rates of the DOS group were 80.33%, 73.77% and 62.30%, and the DFS rates of the SOX group were 73.85%, 55.38% and 41.54%. The difference in DFS between the two groups was statistically significant ( χ2 = 5.43, P = 0.022). The 1-, 2- and 3-year overall survival (OS) rates of the DOS group were 93.44%, 80.33% and 70.50%, and the OS rates of the SOX group were 96.92%, 73.85% and 52.31%. The difference in OS between the two groups was statistically significant ( χ2 = 4.38, P = 0.045). There were no statistical differences in the incidence rates of grade Ⅰ-Ⅱ nausea, vomiting, diarrhea, bone marrow suppression and fatigue between the two groups (all P > 0.05). There were no statistical differences in the incidence rates of grade Ⅲ-Ⅳ nausea, vomiting and fatigue (both P > 0.05), but there were statistical significances in the incidence rates of grade Ⅲ-Ⅳ diarrhea and bone marrow suppression (both P < 0.05). Conclusions:Adjuvant DOS regimen in the treatment of advanced gastric adenocarcinoma after D2 radical resection has good curative efficacy and can improve the survival of patients, and the adverse reactions can be tolerated.

ABSTRACT

Objective:To construct a multi-label learning MRI model for assisting diagnosis of sports injury in knee.Methods:A total of 1 391 knee MRI cases from 1 343 young adults with sports injury in Affiliated Jinling Hospital Nanjing University School of Medicine were retrospectively enrolled. The image cases were randomly divided into training set ( n=973), validation set ( n=139) and test set ( n=279) with ratio of 7∶1∶2. The knee injuries were divided into six categories: meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury. Using PyTorch V1.1.0 algorithm package, the Yolo model of deep learning was used to construct the MRI knee joint sports injury detection model. The model was validated on the test set, and the sensitivity, specificity and mean average precision of lesion detection were evaluated. Results:Among the 279 patients in test set, the mean average precision of meniscus injury, tendon injury, ligament injury, osteochondral injury, synovial bursa disorder and soft tissue injury were 83.1%, 89.0%, 88.0%, 85.8%, 85.5% and 83.2%, respectively, and the overall mean average precision was 85.8%. The model was most effective in detecting tendon injury. The sensitivity and specificity of the model for tendon injury were 91.2% and 87.1% respectively.Conclusions:The multi-label MRI knee joint exercise-related injury detection model based on deep learning can effectively assist in detecting the exercise-related injury of knee joint in each tissue structure, and is expected to improve the efficiency of diagnosis and treatment in orthopedics.

ABSTRACT

Objective:To investigate the effect of long-term application of prostaglandin analog drops on bulbar conjunctival thickness in rabbits.Methods:Twenty-four healthy New Zealand white rabbits were randomly divided into latanoprost group, carteolol group and blank control group using the random number table method, with 8 rabbits in each group.The left eyes of rabbits were taken as experimental eyes.The rabbits in the latanoprost group and carteolol group were given latanoprost eye drops or carteolol eye drops once a day for 2 months according to grouping.The bulbar conjunctival thickness of left eyes of the latanoprost group and carteolol group were measured by optical coherence tomography (OCT) at baseline and two months after administration, respectively.The conjunctival tissue of the three groups were extracted to investigate the protein and mRNA expression level of matrix metalloproteinases-1 (MMP-1) and MMP-3 by Western blot and real-time fluorescence quantitative polymerase chain reaction (PCR). The study protocol was approved by an Ethics Committee of Putuo Hospital Affiliated to Shanghai University of Traditional Chinese Medicine (No.2017-0014). The use and care of the experimental animals complied with the ARVO Statement.Results:In the latanoprost group, the conjunctival thickness was significantly reduced from baseline (178.88±5.23)μm to (124.19±11.29)μm at 2 months after administration ( P<0.01). In the carteolol group, there existed no significant difference in the conjunctival thickness between baseline (184.94±11.85)μm and (183.31±8.71)μm at 2 months after administration ( P>0.05). The conjunctival thickness at 2 months after administration of the latanoprost group was significantly thinner than that of the carteolol group ( P<0.01). The protein and mRNA expression levels of MMP-1 and MMP-3 in conjunctival tissue of the latanoprost group were significantly higher than those of the blank control group and carteolol group (all at P<0.01). Conclusions:The long-term topical use of prostaglandin analog drops can significantly reduce the bulbar conjunctival thickness in rabbits.The mechanism may be related to the elevated expression levels of MMP-1 and MMP-3 in the bulbar conjunctival tissue.

ABSTRACT

Objective:To investigate the incidence and clinical characteristics of cranial imaging abnormalities in children with systemic lupus erythematosus (SLE) at the initial diagnosis.Methods:The clinical data of 74 children with SLE admitted to the Department of Rheumatology in Children′s Hospital Affiliated to Xi′an Jiaotong University for the initial diagnosis from January 2012 to May 2019 were subject to retrospective analysis.They were divided into the cranial imaging abnormality group and the cranial imaging non-abnormality group according to the imaging.A description and statistical analysis were carried out for both groups with respect to the course before initial diagnosis, gender, rash, arthralgia, hair loss, pulmonary lesions, white blood cells (WBC), hemoglobin (Hb), platelets (PLT), erythrocyte sedimentation rate (ESR), serum ferritin (FER), serum complement values (C 3 and C 4), anticardiolipin antibody (ACA), alanine aminotransferase (ALT), aspartate transaminase (AST), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and total cholesterol (TC). Results:Seventy-four children with SLE underwent a cranial imaging exa-mination at the initial diagnosis, including 52 cases for magnetic resonance imaging (MRI) and 22 cases for CT.There were 36 abnormal cases (48.6%), including 27 cases (51.9%) in MRI and 9 cases (40.9%) in CT.Among 36 cases of abnormal cranial imaging in children with SLE, MRI abnormalities were mainly demyelinating lesions and sulcus widening (brain atrophy), while CT abnormalities were mainly sulcus widening (brain atrophy). There were 21 cases presenting with neurological symptoms, including 17 cases of headache, 11 cases of dizziness, 3 cases of convulsions, and 1 case of coma.There were no significant differences between both groups in the course before initial diagnosis, gender, rash, arthralgia and hair loss.Among the 36 cases of SLE with cranial imaging abnormalities, 20 cases presented with interstitial pulmonary lesions, of which 4 cases presented with pulmonary hemorrhage; Among 38 cases of SLE without cranial imaging abnormality, 8 cases presented with interstitial pulmonary lesions, which indicated that there were statistical differences between both groups; within terms of the laboratory test items, there were significant differences in PLT between both groups, and there was no significant difference in WBC, Hb, ESR, FER, C 3, C 4, ACA, ALT, AST, TG, HDL, LDL and TC. Conclusions:The cranial imaging abnormalities in children with SLE, especially the earlier occurrence in MRI, may occur before the manifestation of clinical symptoms of the nervous system.They were also associated with other important organ damages, such as abnormal blood system and lung lesions.Early detection may contribute to the short-term prognosis.

ABSTRACT

Objective:To explore the anatomic repair strategy for congenital corrected transposition of great arteries (ccTGA).Methods:At the retrospective study, from August 2004 to May 2019, all 120 consecutive ccTGA were included and all accepted anatomic repair. There were 36 cases with with left ventricular outlet obstruction(LVOTO) and cardiac malpositon [ages(4.6±2.2) years, weight(17.7±5.9)kg] underwent the one and a half ventricle repair(hemi-Mustard and bidirectional Glenn procedures combined with the Rastelli), 49 cases[ages(3.4±2.7) years, weight(17.7±11.4)kg] underwent double switch operation(Great artery swtich with Senning operation), 24 cases [ages(5.7±4.3) years, weight(19.1±8.6)kg] with LVOTO and ventricular sept defect(VSD) accepted the Rastelli with Senning operation, and 14 cases with LVOTO and remote VSD [ages(6.9±4.8) years, weight(23.0±12.9)kg] accepted the Double root transposition(DRT) with Senning operation. Follow up data were collected by telephone interviews and echo. The median follow-up time were 49 months varied from 20 to 84 months, 46 months varied from 18 to 108 months, 35 months varied from 7 to 84 months and 98 months varied from 72 to 145 months. Statistical analysis was performed with SPSS 19.0.Results:There were 6 in-hospital deaths and 2 follow-up deaths. The survival probability were(84.0±6.0)% and(84.0±6.0)% at 5 and 10 years after operation. The probability of freedom from re-intervention were(95.0±11.8)% and(89.0±11.8)% at 5 and 10 years after operation. All 6 patients need implant pacemaker for Ⅲ A-V block. Seven patients had moderate or more than moderate tricuspid regurgitation. The left ventricular(systemic ventricle) EF were 0.61±0.09, 0.63±0.08, 0.59±0.01 and 0.65±0.07 in one and a half ventricle repair group, double switch(AS group), Rastelli with Senning(RS group) and DRT with Senning(DS group) patients. There were 1 heart failure in one and a half ventricle repair group, 1 in AS group and 1 in RS group. For 36 pure ccTGA patients, compared with direct double switch patients these patients accepting double switch after pulmonary banding(PAB) had more EF(0.54±0.09 vs. 0.65±0.08, P=0.00). There were significantly less patients need re-operation in one and a half ventricle repair group compared with RS group(0 vs. 13.6%, P=0.03). Conclusion:For ccTGA/LVOTO/cardiac malpositon, the one and a half ventricle repair was ideal strategy with significant less RV-PA conduit stenosis and re-operation. For pure ccTGA patients, second staged double switch after PAB had better long-term heart function. For ccTGA/ LVOTO/ remote VSD patients DRT with Senning was ideal strategy.

ABSTRACT

Objectives:To validate the Chinese version of the Ureteral Stent Symptoms Questionnaire(Chinese-USSQ) in patients with an indwelling ureteral stent.Methods:The original USSQ was translated into Chinese and linguistically validated following the cross-cultural adaptation of health-related quality of life measures.A total of 83 patients (cases) with indwelling ureteral stent and 90 healthy subjects (controls) were asked to complete the Chinese-USSQ as well as European Quality of Life Visual Analogue scale(EQ-VAS)(for both genders), the International Prostate Symptom Scale (IPSS) (for male), and Urogenital Distress Inventory-6 (for female). Patients were evaluated at weeks 1 and 4 after stent placement and at week 4 after removal. The psychometric properties of the questionnaire were analyzed.Results:The Chinese version of USSQ include 43 items, which addressed various domains of health(6 sections) covering urinary symptoms, pain, general health, work performance and sexual matters with additional problems. A total of 78 patients(45 males and 33 females) and 90 controls (41 males and 49 females)were included for analysis. Internal consistencies (Cronbach′s α coefficients: 0.60-0.78) and test-retest reliability (Spearman correlation coefficient: 0.69-0.91) were satisfactory for urinary symptom, body pain, general health, and work performance domains. Most USSQ domains showed moderate correlations with each other. The convergent validity determined by correlation between other instruments and corresponding USSQ domain was satisfactory. At week 4 it was moderate for the urinary symptoms index compared to the IPSS in men(Spearman correlation coefficient>0.60), for the urinalry symptoms index compared to the UDI-6 score in women(Spearman correlation coefficient 0.52).Sensitivity to change and discriminant validity were also good in most domains ( P<0.01). Only a small proportion of the study population had an active sexual life with the stent in situ, which limited its analysis. Only 1(1.3%) and 6(7.7%) patients had an active sex life at week 1 and 4 after stent placement; meanwhile, 34(43.6%) patents were sexually active at week 4 after stent removal. Conclusion:The Chinese version of the USSQ is a reliable and valid instrument that can be used for Chinese patients with a indwelling ureteral stent in the clinical and research settings.

ABSTRACT

@#Objective    To explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion. Methods    We retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews. Results    There was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found. Conclusion    For patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.

ABSTRACT

@#Objective    To explore the appropriate method of biventricular repair and analyze the risk factors for reoperation, by summarizing the 15-year treatment experience of biventricular repair for double outlet right ventricle with non-committed ventricular septal defect (DORVncVSD). Methods    Clinical data of 162 consecutive patients with DORVncVSD who had biventricular repair from 2005 to 2019 in our center were retrospectively analyzed. The children were divided into two groups according to the path of intracardiac tunnel: 110 patients with ventricular septal defect rerouted to the aorta were recruited into a group A (75 males and 35 females aged 3.6±3.2 years); 52 patients with ventricular septal defect rerouted to the pulmonary artery were into a group B (30 males and 22 females aged 2.8±2.7 years). In order to establish a smooth intracardiac tunnel, enlargement of VSD, the resection of conus muscle and the transfer of tricuspid tendon or papillary muscle, etc were performed at the same time. Results    In the patients with biventricular repair, there were 9 (5.6%) early deaths and 6 (3.7%) early intracardiac baffle obstructions. During the follow-up of 7.5±7.0 years, and 8 (4.9%) late deaths occurred. The 1-year, 5-year, 10-year and 15-year survival rates of the group A were 92.7%, 91.1%, 91.1%, 85.4%, respectively and those of the group B were 92.2%, 85.2%, 85.2%, 85.2%, respectively. The difference between the two groups was not statistically significant (P=0.560). The follow-up results showed that 10 (6.2%) patients had late-onset intracardiac tunnel obstruction, and 8 patients underwent reoperation. There were more late-onset intracardiac tunnel obstruction patients and overall intracardiac tunnel obstruction patients in the group A than those in the group B (9 patients vs. 1 patient, P=0.017; 15 patients vs. 1 patient, P=0.001). No significant difference of early mortality and late mortality was noted for the group A (P=0.386) and the group B (P=0.223). Also it was noted that performing tricuspid valve operation at the same time in the group A had a significant impact to reduce the occurrence rate of intracardiac obstruction (1/46 vs. 15/64, P=0.004), without any tricuspid regurgitation or stenosis. The reoperation rate of patients with Rastelli after right ventricular outflow tract lesions was significantly higher than that of REV surgery and double root replacement surgery (5/14 vs. 0/38, P<0.001). Conclusion    The effect of biventricular repair for DORVncVSD is satisfactory. And concomitant tricuspid procedures can help reduce the occurrence of intracardiac obstructions. Reconstruction of right ventricular outflow tract with biological valved conduit is a risk factor for reoperation.

ABSTRACT

@#Objective    To report the short-term outcomes of a standardized, simplified and reproducible strategy of mitral valvuloplasty (MVP), which was focused on leaflet foldoplasty and anatomic anomalies of congenital mitral regurgitation (MR). Methods    Consecutive 74 patients who underwent MVP by our standardized strategy in our institution from 2016 to 2018 were included retrospectively. There were 30 males and 44 females with a median age of 18.5 (6-146) months and weight of 15.4 (7-51) kg. Results    Anatomic anomalies of MR included: (1) subvalvular apparatus: 72 (97.3%) patients with mal-connected chordae tendineae, 31 (41.9%) with absent chordae tendineae and 14 (18.9%) with fused or dysplastic papillary muscle; (2) leaflet: 10 (13.5%) patients with cleft of anterior leaflet, 61 (82.4%) with leaflet prolapse including 56 (91.8%) with anterior leaflet prolapse; (3) annulus: 71 (95.9%) patients with annular dilatation. Leaflet foldoplasty was performed in 61 (82.4%) patients with leaflet prolapse. All patients were successfully discharged and 4 (5.4%) patients were with moderate MR. The follow-up time was 22.0 (9.1-41.8) months. During the follow-up period, 3 patients had moderate MR and 1 patient had reoperation for severe MR. All patients were in normal cardiac function with a mean left ventricular ejection fraction of 66.0%±6.1%. In addition, the mean left ventricular end-diastolic dimension was 31.8±6.0 mm, which was significant smaller than that before the operation (t=6.090, P<0.000 1). Conclusion    The standardized leaflet foldoplasty with resection of mal-connected chordae tendineae and posterior annuloplasty technique is safe and feasible with favorable short-term outcomes in MR patients.

ABSTRACT

@#Objective    To analyze the results of surgical treatment of severe aortic stenosis in infants. Methods    From August 2012 to December 2019, 28 infants undergoing aortic valvuloplasty in our hospital were selected, including 22 males and 6 females, aged 62.00 (47.00, 82.50) d. The baseline characteristics of the patients, postoperative complications and follow-up results were analyzed. Results    Twenty (71.43%) patients had bicuspid aortic valves. Five (17.86%) patients had heart failure and two (7.14%) patients used prostaglandin before surgeries. Postoperative mechanical ventilation time was 25.00 (17.00, 62.75) h, ICU stay was 3.50 (2.00, 8.50) d and postoperative hospital stay was 10.00 (7.00, 16.50) d. Four (14.29%) patients got delayed recovery (ICU stay>14 d). One (3.57%) perioperative death was observed. The follow-up time was 55.00 (43.25, 82.25) months. No death was found during follow-up. Four (14.81%) patients underwent a second operation, including three (11.11%) patients with severe aortic stenosis, and one (3.70%) patient with severe regurgitation. Conclusion    Infants with severe aortic stenosis are seriously ill and have a long postoperative recovery time, requiring early surgery. The postoperative follow-up results are satisfactory.
