Objective To summarize the results and clinical experience of transcatheter valve-in-valve implantation using domestic self-expanding valve in patients with aortic degenerated bio-prosthesis. Methods From January 2019 to April 2023, the patients who underwent transcatheter valve-in-valve surgery in the Department of Cardiac Surgery of Tianjin Chest Hospital due to surgical bio-prosthesis failure were included. Characteristics of valves, perioperative complications, and hemodynamic manifestations during the early postoperative and follow-up period were analyzed. Results A total of 24 patients were enrolled, including 14 males and 10 females with an average age of 68.17±7.72 years, and the average interval between the two operations was 10.48±4.09 years. All patients were successfully discharged without complications such as coronary artery obstruction and pacemaker implantation, and the average transvalvular pressure gradient was 16.39±6.52 mm Hg before discharge. During the median follow-up time of 16 months, the left ventricular diastolic inner diameter and ejection fraction were continuously improved. Conclusion Transcatheter valve-in-valve using domestic self-expanding valves is safe and feasible to treat aortic bioprosthetic valve failure. Sound patient selection and surgical strategies are critical to achieve good hemodynamics.

Objective To analyze the short-term clinical efficacy and prognosis of one-stop transcatheter aortic valve replacement (TAVR)+percutaneous coronary intervention (PCI) in the treatment of aortic valve disease with coronary heart disease. Methods The clinical data of patients with aortic valve disease complicated with coronary heart disease who underwent one-stop TAVR+PCI treatment at the Department of Cardiovascular Surgery, the Second Hospital of Hebei Medical University from January 2018 to June 2023 were retrospective analyzed. The preoperative and postoperative clinical data were compared, and 1-month follow-up results were recorded. Results A total of 37 patients were enrolled, including 22 males and 15 females, with an average age of 69.14±6.47 years. Thirty-six patients recovered and were discharged after the surgery, and 1 (2.7%) patient died during the surgery. Self-expanding TAVR valves were implanted through the femoral artery in all patients. One coronary artery was opened by PCI in 35 (94.6%) patients, and two coronary arteries were opened by PCI in 2 (5.4%) patients. All PCI opened arteries had a stenosis>70%. During the postoperative hospitalization, the complications included pulmonary infection in 11 (30.6%) patients, severe pneumonia in 10 (27.8%) patients, liver function injury in 14 (38.9%) patients, renal function injury in 5 (13.9%) patients, cerebral infarction in 1 (2.8%) patient, atrial fibrillation in 1 (2.8%) patient, ventricular premature beats in 2 (5.6%) patients, atrioventricular block in 2 (5.6%) patients, and complete left bundle branch block in 5 (13.9%) patients. The median postoperative ventilation assistance time was 12.0 (0.0, 17.0) h, the ICU monitoring time was 1.0 (0.0, 2.0) d, and the postoperative hospitalization time was 5.0 (4.0, 7.0) d. There was a significant improvement in the New York Heart Association cardiac function grading after surgery (P<0.001). After surgery, there were 21 (58.3%) patients had minor perivalve leakage, 6 (16.7%) patients had minor to moderate perivalve leakage, and no moderate or above degree of perivalve leakage. After one month of postoperative follow-up, 36 patients showed significant improvement in heart function. There were no patients with recurrent acute coronary syndrome, re-PCI, or cardiovascular system disease related re-hospitalization. Conclusion The one-stop TAVR+PCI treatment for patients with aortic valve disease and coronary heart disease can obtain satisfactory short-term clinical efficacy, which is worth further trying and studying.

Objective:To explore the clinical phenotype and genetic etiology for seven children with CHARGE syndrome (CS).Methods:Clinical data of 7 children with CS diagnosed between March 2020 and December 2022 at the Children′s Hospital Affiliated to Zhengzhou University were analyzed. Genomic DNA was extracted from peripheral blood samples from the children and their parents, and subjected to whole exome sequencing. Candidate variants were verified by Sanger sequencing and pathogenicity analysis. This study was approved by the Medical Ethics Committee of the Children′s Hospital Affiliatedto Zhengzhou University (Ethics No. 2024-K-023).Results:The ages of the children had ranged from 1 day after birth to 12 years old, and all of them had shown growth retardation. The reasons for their admission had included postnatal breathing, swallowing and feeding difficulties in five cases. One child was found to have abnormal external genitalia in conjunct with hearing impairment, whilst another child had shown no secondary sexual characteristics during puberty. All of the children were found to harbor CHD7 gene variants, which included 3 nonsense variants, 2 frameshifting variants and 2 missense variants, i. e., c. 6292C>T (p.R2098*), c.2754G>A (p.W918*), c. 469C>T (p.R157*), c. 3308T>A (p.V1103D), c. 7111delC (p.Q2371Kfs), c. 6023delA (p.D2008Vfs) and c. 3565C>T (p.R1189C). All of the variants were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 3308T>A (p.V1103D) and c. 3565C>T (p.R1189C) variants were rated as likely pathogenic (PS2+ PM2_Supporting+ PP3), whilst the remainders were rated as pathogenic (PVS1+ PS2+ PM2_Supporting). Conclusion:There is strong clinical and genetic heterogeneity in CS. Early genetic testing may facilitate accurate diagnosis. The detection of novel variants has expanded the phenotypic spectrum of CS and the mutational spectrum of the CHD7 gene.

Objective To investigate the efficacy of red and blue lights combined with Yufa Shengfa solution and 5% minoxidil solution in treating Ludwig type Ⅰ female androgenetic alopecia. Methods A total of 160 patients with Ludwig type Ⅰ female androgenetic alopecia were randomly divided into group A (Yufa Shengfa solution combined with 5% minoxidil solution), group B (red and blue lights therapy combined with Yufa Shengfa solution), group C (red and blue lights therapy combined with 5% minoxidil solution) and group D (red and blue lights therapy combined with Yufa Shengfa solution and 5% minoxidil solution), with 40 cases in each group. All the patients orally took compound glycyrrhizin tablets and Centrum multivitamins, and the therapeutic period was 3 months. Differences in hair diameter, hair density, and the number of hair follicles with multiple hairs were compared before and after treatment. Results The hair density, hair diameter, and the number of hair follicles with multiple hairs improved significantly in 4 groups compared with those before treatment, and group D showed the best improvement in these parameters, with significant between-group differences (P < 0.001). There were no serious adverse events or side effects during treatment in all the patients. Conclusion Red and blue lights therapy combined with Yufa Shengfa solution and 5% minoxidil solution is an effective non-surgical treatment for Ludwig type Ⅰ female androgenetic alopecia.

Objective:Explore the feasibility and advantages of using proximal and distal ends of thoracodosal artery and vein as recipient vessels in deep inferior epigastric perforator flap immediate breast reconstruction.Methods:The clinical data of patients who underwent breast reconstruction surgery using the proximal and distal ends of the thoracodorsal vein as recipient vessels at the Department of Breast and Thyroid Surgery of the Second Affiliated Hospital of Hainan Medical University from March 2022 to June 2023 were analyzed retrospectively. Preoperative examinations included thoracoabdominal angiography and color Doppler ultrasonic localization of the main trunk and perforators of the inferior epigastric vessels. The procedure began with mastectomy and axillary lymph node dissection, followed by the isolation of bilateral perforators and the main trunk of the abdominal flap. The main trunks of the bilateral inferior epigastric arteries were then transected, and their vascular pedicles exposed and anastomosed respectively to the proximal and distal ends of the thoracodorsal artery and vein. Both arteries and veins were joined end-to-end. The flap after trimming and reconstruction was then implanted into the cavity left after mastectomy through the incision. Breast positioning was performed with the patient in a knee-bent and hip-flexed position. After adjusting the shape of the reconstructed breast. The donor site was closed, the umbilicus was reconstructed, drainage tubes were placed, and the breast incision was closed. Postoperative follow-up monitored complications associated with the flap and patient satisfaction with the breast reconstruction, utilizing a self-assessment method.Results:Four female patients were included, aged (46.0±6.5) years, ranging from 37 to 52 years. All four patients had bilateral vascular pedicles in the donor area, with three patients having thoracodorsal vessels at the distal and proximal ends as recipient vessels, and one patient having anterior serratus branch of the thoracodorsal vessels at the distal and proximal ends. All drainage tubes were removed within 7 to 10 days after surgery. Patients were discharged. Follow-up period ranged from 1 to 15 months, averaging 6 months. The patients recovered well postoperatively, with no flap-related complications occurring. All four patients were satisfied with the result of the reconstruction.Conclusion:The simultaneous application of the proximal and distal ends of the thoracodorsal artery and vein can ensure the safety of flap survival while reducing damage to the ribs and intercostal muscles, achieving better aesthetic result.
