Currently, transcatheter intervention is the preferred treatment for patients with anatomically suitable atrial septal defects. However, the use of nickel-titanium alloy occluders in interventional procedures results in lifelong presence of the implant in the body, leading to complications such as metal allergies and arrhythmias in some patients. To overcome the short-term and long-term complications associated with the presence of metal, and to avoid radiation exposure and metal toxicity, this paper reports a case of successful transcatheter closure of atrial septal defect in a pediatric patient with metal allergies using fully biodegradable occluder under ultrasound guidance, achieving excellent results by interventional therapy.

BACKGROUND:It has been hypothesized that PANoptosis may be involved in the pathologic process of osteoporosis,but there have been no studies addressing the mechanisms of PANoptosis genes in osteoporosis. OBJECTIVE:To analyze the biological mechanism of PANoptosis regulators in the occurrence and development of osteoporosis. METHODS:The GSE56815 dataset was obtained from the Gene Expression Omnibus database and PANoptosis genes were extracted for differential analysis.The key genes of PANoptosis were screened by random forest tree model to construct a disease risk prediction model.Consensus clustering algorithm,single sample genome enrichment analysis and immune infiltration analysis were used to explore the differences between different PANoptosis molecular subtypes.Herbal drugs that regulate the key genes of PANoptosis were predicted through Coremine medical database,a medical ontology information retrieval platform. RESULTS AND CONCLUSION:Based on the four PANoptosis key genes(CASP1,CASP10,MEFV,and TNF),the diagnostic markers of osteoporosis were determined,and the risk prediction model was constructed and verified.Osteoporosis was divided into two different PANoptosis subtypes(clusters A,B and gene clusters A,B),and the PANoptosis scores of cluster B and gene cluster B were higher than those of cluster A and gene cluster A,respectively.Traditional Chinese drugs such as ginseng which can regulate the key genes of PANoptosis were predicted by the Coremine medical database.

OBJECTIVE: To assess the association of genomic instability of epithelial cadherin 1 (CDH1) gene and clinicopathological characteristics of gastric cancer. METHODS: In total 120 paraffin-embedded gastric cancer tissue specimen were prepared, and genomic DNA was extracted. The genomic instability of the CDH1 gene was analyzed by immunohistochemistry and silver staining PCR-single-strand conformation polymorphism. RESULTS: The number of information individuals (heterozygotes) was 98 for the D16S752 locus. The detection rates for microsatellite instability (MSI) and loss of heterozygosity (LOH) at the D16S752 locus and the positive rate of CDH1 protein were 19.39%, 16.33% and 51.02%, respectively. The detection rate of MSI in TNM stages I or II was significantly higher than that in stages III or IV (P<0.05) while the detection rate of LOH was significantly lower than that in stages III or IV (P<0.05). The positive rate of CDH1 protein in TNM stages III or IV was significantly lower than that in stages I or II (P<0.05). The detection rate of MSI of cases with lymph node metastasis was significantly lower than that of without lymph node metastasis (P<0.05) while the detection rate of LOH was significantly higher than that without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in patients with lymph node metastasis was significantly lower than that in patients without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in MSI-positive group was significantly higher than that in MSI-negative group (P<0.05), and the positive rate of CDH1 protein in the LOH-positive group was significantly lower than that the LOH-negative group (P<0.05). CONCLUSION The genomic instability of the CDH1 gene is associated with the progression of gastric cancer. MSI at the D16S752 locus may be used as a molecular marker for early gastric cancer, while LOH at this locus mostly occurs in advanced gastric cancer and can be regarded as an effective indicators for malignancy evaluation and prognosis.

Objective:To explore the effects of continuous nursing based on timing theory on quality of life, self-care ability and caring ability of family caregivers of male patients with first-episode depression.Methods:From March 2018 to March 2020, the convenient sampling was used to select 100 male patients with depression and 100 caregivers who were hospitalized in the First Department of Mood Disorders in the Second Affiliated Hospital of Xinxiang Medical University as the research objects. The patients and their caregivers were divided into the experimental group and the control group by the random number table method, with 50 patients and 50 caregivers in each group. The control group received routine nursing and follow-up, while the experimental group received continuous nursing intervention based on timing theory for 6 months on this basis. Hamilton Depression Scale (HAMD) , Hamilton Anxiety Scale (HAMA) , World Health Organization on Quality of Life Brief Scale (WHOQOL-BREF) , Exercise of Self-Care Agency Scale (ESCA) and Family Caregiver Task Inventory (FCTI) scale were used in the control group and the experimental group. The patients and their families were evaluated at 72 h after admission, at discharge, 3 months after discharge and 6 months after discharge.Results:After the intervention, the scores of HAMA and HAMD in the experimental group were lower than those in the control group, and the scores of each dimension of WHOQOL-BREF were higher than those in the control group, and the differences between the two groups were statistically significant ( P<0.01) . At the time of discharge, 3 months and 6 months after discharge, the total score of the FCTI scale of the caregivers in the experimental group was lower than that of the control group, and the ESCA total score of the patients was higher than that of the control group, and the differences between the two groups were statistically significant ( P<0.01) . Conclusions:Continuous nursing based on timing theory can effectively relieve anxiety and depression of male patients with first-episode depression, improve quality of life and self-care ability of patients and improve the care level of family caregivers.

Objective To investigate the effects of miR-325-3p on the EMT, invasion and metastasis of gastric cancer cells by targeting CLDN1 gene. Methods We selected human gastric epithelial cell lines GES-1 and gastric cancer cell lines HGC27, SGC-7901, MKN-45 and MGC-803, and detected the expression of miR-325-3p and CLDN1. The targeting relation between miR-325-3p and CLDN1 were verified by dual luciferase report experiments, and the expression of miR-325-3p and CLDN1 in gastric cancer cells were intervened. qRT-PCR and Western blot were adopted to detect N-cadherin, vimentin and MMP2 expression in cells. CCK-8 assay, Transwell assay, flow cytometry were utilized to detect cell proliferation activity, invasion and apoptosis, respectively. Results Compared with GES-1 cells, miR-325-3p expression was decreased while CLDN1 expression was increased in MGC-803 cells (P < 0.05). CLDN1 was a target gene of miR-325-3p. Overexpression of miR-325-3p could inhibit the proliferation, invasion and EMT of gastric cancer cells, while promote the apoptosis of gastric cancer cells. However, the inhibition of miR-325-3p had the opposite effect (P < 0.05). The overexpression of CLDN1 could reverse the effect of miR-325-3p overexpression on the biological behavior of gastric cancer cells. Conclusion miR-325-3p can suppress CLDN1, inhibit the invasion, metastasis and EMT while promote the apoptosis of gastric cancer cells. miR-325-3p is expected to be a new target in gastric cancer treatment.

Objective To analyze the midterm outcome of patients with congenital aortic stenosis undergoing percutaneous balloon aortic valvuloplasty (PBAV) by single echocardiographic guidance. Methods The clinical data of 12 patients with congenital aortic stenosis who underwent PBAV by single echocardiographic guidance at Fuwai Hospital from January 2016 to November 2017 were retrospectively analyzed. There were 7 males and 5 females with an average age of 18.27±15.30 years. The preoperative peak pressure gradient was 61.8–110.0 (80.30±24.50) mm Hg, and 50% of patients had aortic regurgitation. Results All patients successfully underwent PBAV. Aortic annulus diameter was 18.65±3.17 mm and balloon diameter was 17.62±3.77 mm, with balloon diameter to annulus diameter ratio of 0.92±0.07. The peak transaortic gradient was 16-51 (36.72±12.33) mm Hg immediately after procedure, which was significantly different from the preoperation (P=0.000). During the follow-up period, the peak transaortic gradient was 21-58 (37.06±13.52) mm Hg, and there was no significant difference between the follow-up and immediate postoperation (P=0.310). Immediately after procedure and during follow-up, 58% of patients had aortic regurgitation, which was not statistically different from the preoperation (P=0.682). Conclusion Systematic use of Doppler echocardiographic guidance for PBAV is feasible, and that it is associated with a high success rate and a very low complication rate.

Objective    To assess the efficacy and safety of percutaneous closure of patent ductus arteriosus (PDA) solely under echocardiography guidance. Methods    We retrospectively analyzed the clinical data of 200 patients who received the percutaneous closure of PDA under echocardiography guidance in Fuwai Hospital from August 2013 to April 2016. According the different approach, they were divided into 2 groups: a femoral artery approach group (n=143) and a femoral vein approach group (n=57). In the femoral artery approach group, there were 42 males and 101 females aged 3.20±5.63 years. In the femoral vein group, there were 10 males and 47 females aged 7.30±11.36 years. All Patients were treated by percutaneous PDA closure solely under echocardiography guidance. The follow-up was performed at one month after the operation by echocardiography, chest radiograph and electrocardiogram. Results    All 200 patients were successfully treated with percutaneous closure of PDA. The patients’ gender, in-hospital stay, rates of occluder  detachment were similar between the two groups (P>0.05). Compared with the femoral vein approach group, the femoral artery approach group had a younger age (3.20±5.63 years vs. 7.30±11.36 years, P<0.001), less body weight (14.25±11.54 kg vs. 24.25±19.14 kg, P<0.001) and shorter diameter of PDA (3.06±0.79 mm vs. 5.93±0.68 mm, P<0.001) and PDA occluders (5.43±1.00 mm vs. 12.14±0.54 mm, P<0.001), but had higher hospitalization expenses (32 108.2±3 100.2 yuan vs. 25 120.7±3 534.1 yuan, P<0.001). In the femoral vein approach group, one patient was closed under radiation guidance because guide wires could not pass through PDA. One patient in the femoral artery approach group suffered from occluder detachment at one day after operation and was cured by transthoracic minimally invasive PDA occlusion. There were no complications of occluder detachment, residual shunt, pericardial effusion or left pulmonary stenosis during the follow-up. Conclusion    Echocardiography-guided percutaneous PDA closure is safe and effective, while the proper interventional approach should be chosen by the anatomical features of PDA.
