Objective To evaluate the clinical value of transarterial catheterization C-arm CT perfusion scanning technique during prostatic artery embolization(PAE)for benign prostatic hyperplasia(BPH).Methods The clinical data of 46 patients with BPH received PAE were analyzed retrospectively.All patients underwent prostatic artery(PA)digital subtraction angiography(DSA)and C-arm CT perfusion scanning to identify PA and prevent non-target organ embolization.The final recognization of PA was consulted by three senior doctors.After C-arm CT confirmation,PA was embolized with 100-300 μm polyvinyl alcohol(PVA)particles or microspheres under fluoroscopy.The postoperative complications and 3-month clinical efficacy were observed.Results A total of 106 vessels were angioraphed in 46 patients,with 83 PA vessels and 23 non-PA vessels.PA was identified by DSA and C-arm CT with sensitivity of 81.9%(68/83)and 100%(83/83),respectively,which showed significance(χ2=22.3,P<0.01).Non-PA was identified by DSA and C-arm CT with specificity of 73.9%(17/23)and 100%(23/23),which showed significance(χ2=9.2,P=0.02).No serious complications were observed and 3-month clincial efficacy was 91.3%.Conclusion Transarterial catheterization C-arm CT perfusion scanning technique can accurately identify PA,reduce PA leakage and prevent non-target organ embolization.

Objective To evaluate the efficacy of microwave ablation(MWA)synchronously with biopsy for pulmonary nodules.Methods The data of 64 patients with MWA combined with biopsy were analyzed retrospectively.Thirty-one patients(non-synchronous group)were treated with ablation following biopsy in turn to identify malignant tumors,and 33 patients(synchronous group)were treated by ablation and biopsy synchronously.The technical success rate,operation time,complications,hospitalization time and expenses were compared between non-synchronous group and synchronous group.Results The technical success rate,pneumothorax,and pleural effusion rate showed no significance between the two groups(P>0.05).There were all significant differences in operation time(42.00 min vs 54.26 min),hospitalization time(5.09 days vs 9.26 days),hospitalization expenses(26 840.61 yuan vs 32 527.26 yuan),lung hemorrhage(27.27%vs 87.10%)and hemoptysis(3.03%vs 19.35%)between synchronous group and non-synchronous group,respectively(P<0.05).Conclusion MWA synchronously with biopsy for pulmonary nodules is safe and feasible,which can reduce intraoperative bleeding,shorten treatment period and reduce hospitalization expenses.

Objective To explore the efficiency and safety of trans-sheath intraluminal forceps biopsy under digital subtraction angiography(DSA)guidance for assisting diagnosis of pulmonary artery obstructive diseases.Methods Data of 16 patients who underwent trans-sheath intraluminal forceps biopsy for pulmonary artery obstructive diseases were retrospectively analyzed,and the clinical manifestations were recorded.The technical success of biopsy was defined as tissue obtained met the needs of pathology diagnosis.For patients with malignant pathology results,the final diagnosis was malignant,for those with benign pathology results after biopsy and no obvious changes after 6-month or longer follow-up,or benign pathology results after surgical resection,the final diagnosis was benign,otherwise was no clear diagnosis.The operation time,technical success rate,diagnostic efficiency,complications and changes of pulmonary artery pressure before and after the biopsy were observed.Results Among 16 patients,9 complained of intermittent chest tightness,4 complained of chest pain with chest tightness,2 complained of chest pain but 1 denied any symptoms.The lesions located in the left lung in 10 cases and in the right lung in 6 cases,all with enhanced CT showed filling defects of the involved branch of pulmonary artery.Totally 16 trans-sheath intraluminal forceps biopsies were performed in 16 patients,with an average operation time of(31.02±6.02)min and technical success rate of 100%.Malignant tumors were finally diagnosed in 10 cases,including 1 case of lung cancer with false-negative biopsy result,while biopsy correctly diagnosed benign lesions in the other 6 cases.Transient worsening chest pain with chest tightness occurred in 2 cases and relieved after symptomatic treatments.No statistically significant difference of pulmonary artery pressure was found before([53.38±14.28]mmHg)and after([53.69±14.15]mmHg)biopsy(P＞0.05).Conclusion DSA-guided trans-sheath intraluminal forceps biopsy was relatively safe and valuable for assisting diagnosis of pulmonary artery obstructive diseases.

Objective:To analyze the risk factors that affect the prognosis of patients with hypopharyngeal squamous cell carcinoma（HPSCC） and to compare the efficacy of surgical resection followed by adjuvant radiotherapy（SR） with that of neoadjuvant therapy consisting of platinum-based chemotherapy and fluorouracil combined with either cetuximab or nimotuzumab, followed by SR. The study also aimed to evaluate the overall survival（OS） of patients, their postoperative eating function, tracheostomy decannulation rate, and tumor response to the two neoadjuvant chemotherapies. Methods:A retrospective analysis was performed on the medical records of HPSCC patients who received SR or neoadjuvant therapy followed by SR treatment at the Shanghai General Hospital from 2012 to 2019 and had not undergone any prior treatment. The prognostic factors were analyzed, and the survival analysis of patients who underwent SR treatment with two neoadjuvant chemotherapy regimens was performed. Results:A total of 108 patients were included in the study. The results of the univariate analysis showed that gender（P=0.850） had no significant correlation with the survival rate of HPSCC patients who underwent SR. However, age, smoking history, alcohol consumption history, platelet-to-lymphocyte ratio（PLR）, neutrophil-to-lymphocyte ratio（NLR）, T stage, N stage, neoadjuvant therapy with either cetuximab or nimotuzumab combined with platinum-based chemotherapy and fluorouracil, and histological grade were significantly associated with prognosis（P<0.05）. The multivariate analysis revealed that smoking history, histological grade, and neoadjuvant therapy with either cetuximab or nimotuzumab combined with platinum-based chemotherapy and fluorouracil were independent risk factors affecting the prognosis of HPSCC（P<0.05）. Patients who received neoadjuvant therapy had longer OS than those who underwent SR only（P<0.001）. There was no significant difference in tumor response to the two neoadjuvant therapies and in OS（P>0.05）, and there was no significant difference in the rate of oral feeding and tracheostomy decannulation among the three treatment groups（P>0.05）. Conclusion:Univariate analysis showed that age at tumor onset, smoking history, alcohol consumption history, NLR, PLR, T stage, N stage, whether receiving neoadjuvant chemotherapy, and pathological grade were associated with the prognosis of HPSCC patients receiving SR treatment. Multivariate analysis showed that smoking history, pathological grade, and neoadjuvant chemotherapy were independent risk factors affecting the prognosis. Neoadjuvant chemotherapy with cetuximab or nimotuzumab can prolong the OS of patients, providing a certain basis and reference for the treatment of HPSCC.

Objective:To observe any effect of repeated magnetic stimulation of the spine on lower urinary tract function and the life quality of patients with neurogenic bladder after suprasacral spinal cord injury (SCI).Methods:Fifteen suprasacral SCI patients whose lower urinary tract function was not improving were enrolled. In the first 2 weeks, all received water drinking management and intermittent catheterization, while in the following 4 weeks they were additionally provided with daily transspinal magnetic stimulation at the level of the spinous process of the first lumbar vertebra five times a week. The stimulation frequency was 1Hz. The patients kept voiding diaries. Their urodynamics were quantified using neurogenic bladder symptom scoring (NBSS) and a life quality scale.Results:The frequency of catheterization and the average voided volume, as well as the maximum detrusor pressure during the storage phase, maximum bladder capacity, maximum urethral pressure during the voiding phase and voiding efficiency at the end of the sixth week were significantly different from those at the end of the second week and before the intervention. The average NBSS and life quality scores then showed significant differences from the earlier time points.Conclusion:Repeteitive transspinal magnetic stimulation of the spine can improve lower urinary tract functioning and the life quality of persons with neurogenic bladder after a suprasacral SCI.

  Objective  To study the demographic and clinical characteristics, correlation of genotype and phenotype and treatment of Blau syndrome to facilitate early diagnosis and timely treatment of Blau syndrome.  Methods  Seventy-two patients with Blau syndrome from 11 centers from May 2006 to April 2022 were retrospectively analyzed, and their general information, clinical data, laboratory examination and treatment medication were collected.  Results  The distribution of patients with Blau syndrome was uniform in geographical north and south of China, and there was no obvious gender bias. The mean age of onset was (14.30±12.81) months, and the age of diagnosis was (55.18±36.22) months. 35% of patients with Blau syndrome happened before 1 year old, and all patients developed before 5 years old. 87.50% (63/72) had granulomatous arthritis, 65.28% (47/72) had rash, 36.11% (26/72) had ocular involvement, 27.78% (20/72) had fever, and 15.28% (11/72) had pulmonary involvement. Arthritic manifestations of Blau syndrome were most at risk, followed by rash, ocular involvement, and fever.The first 25 months of the disease, the risk of developing a rash was the greatest. The risk of developing arthritis was the greatest between 25 months and 84 months. The main mutations were p.R334Q and p.R334W, and patients with p.R334Q mutation had relatively high incidence of fever (35.71%[5/14] vs. 14.29%[1/7], P=0.43) and ocular involvement (42.86%[6/14]vs. 28.57%[2/7], P=0.51). There was a relatively high incidence of rash (85.71%[6/7] vs. 64.29%[9/14], P=0.59) in patients with the p.R334W mutation. Forty-five patients(62.50%)were treated with a combina-tion of glucocorticoid and methotrexate. Twenty-two patients were treated with tumor necrosis factor antagonist in addition to glucocorticoid and methotrexate.  Conclusions  The risk of different clinical manifestations of Blau syndrome from high to low was arthritis, followed by rash, ocular involvement and fever. The main treatment was glucocorticoid combined with methotrexate, to which biological agents could be added.

Objective:To explore the effect of situational behavior record reflection training on the listening ability of newly recruited clinical nurses.Methods:From March to September 2020, cluster sampling was used to select 116 newly recruited clinical nurses from the First Affiliated Hospital of Zhengzhou University as the research object. According to the entry order, nurses were divided into the observation group ( n=58) and the control group ( n=58). The nurses in the control group were trained in accordance with our hospital's regular standardized training system, while the observation group used situational behavior record reflection training method. Before the intervention and 6 months after the intervention, the Hodgetts Listening Performance Scale and the Patient Satisfaction with Nursing Care Questionnaire were used to compare the listening ability and patient satisfaction of the two groups of newly recruited clinical nurses. A total of 116 questionnaires were distributed and 113 valid questionnaires were returned with the valid response rate of 97.41%. Results:Before the intervention, there was no statistically significant differences in the scores of the Hodgetts Listening Performance Scale and the Patient Satisfaction with Nursing Care Questionnaire between the two groups of nurses ( P>0.05). After the intervention, the scores of the Hodgetts Listening Performance Scale and the Patient Satisfaction with Nursing Care Questionnaire of the two groups of nurses were higher than those before the intervention, and those of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.01) . Conclusions:Situational behavior record reflection training can improve the listening ability and patient satisfaction of newly recruited clinical nurses, which is conducive to alleviating the nurse-patient relationship and improving the quality of nursing care.

Objective:To explore the influencing factors of fatigue after stent implantation in patients with airway stenosis.Methods:Totally 104 patients with airway stenosis hospitalized in a hospital from July 2016 to June 2019 were selected, and all the patients were planned to received stent implantation. The patients were evaluated with Identity-Consequence Fatigue Scale (ICFS) postoperatively, and divided into the fatigue group and the non-fatigue group according to the evaluate results. The data of the two groups were consulted, and their gender, age, primary tumor, combined underlying disease, postoperative physical activity, pathological staging, history of radical surgery before stenting, preoperative radiotherapy and chemotherapy, degree of stenosis, type of stenosis, infiltration juga, stent placement site, and re-intervention after stenting were analyzed. Univariate and Logistic regression analysis were performed over the above influencing factors.Results:All the 104 patients with airway stenosis completed postoperative fatigue evaluation. The total score of ICFS was (82.16±8.07) . The scores of postoperative fatigue, attention, vitality, energy, daily activities and the total score were higher than those before operation, and the differences were statistically significant ( P<0.01) . Among the 104 patients with airway stenosis, 28 developed postoperative fatigue, with an incidence of 26.92%. Univariate and multivariate Logistic analysis revealed that postoperative physical activity, pathological staging, infiltrating and re-intervention after stenting were the main influencing factors to fatigue after stent implantation in patients with airway stenosis ( P<0.05) . Conclusions:Patients with airway stenosis have a high incidence of fatigue after stent implantation, which is affected by many factors. Effective intervention measures should be formulated according to the risk factors in order to reduce the incidence of postoperative fatigue.

As an important method to study the phenotype and function of organisms, transcriptome has become one of hot topics in current research. The transcriptomics research usually accompanies with massive data. With the increase of the amount of data, the rules and features hidden in it are not easy to be found. Transforming big data into visual graphics is the most undoubtedly intuitive way to display the hidden information of big data. Several graphs commonly used in transcriptome study were introduced in this paper, such as Venn diagram, heat map, principal component analysis scatter plot, enrichment analysis plot, and time series analysis plot, in order to help readers to choose suitable graphics in future studies.

To evaluate the surgical strategy and follow-up for pulmonary atresia with intact ventricular septum (PA/IVS) in our heart center. Methods    From January 2008 to December 2018, 151 patients with PA/IVS were divided into two groups: a one-stage surgery group (26 patients), including 17 males and 9 females at an average age of 14.7±13.2 months, and a staged surgery group (125 patients) including 72 males and 53 females at an average age of 6.4±6.3 months. The clinical effectiveness of the two groups were analyzed. Results    All patients were followed up for 1-11 years. Eighteen patients died and 19 patients were lost to follow-up. The 1-year, 5-year and 10-year survival rate was 90.2%, 87.0%, and 85.2%, respectively. Two patients died in the one-stage surgery group. Twelve patients died after initial surgery, and 4 patients died after final operation in the staged surgery group. The Z value of tricuspid valve (P=0.013) and severe right ventricular dysplasia (P=0.025) were the risk factors of postoperative death in the patients with PA/IVS. Furthermore, 58 patients completed final operation, and the total number of the final operation (including one-stage radical surgery) accounted for 55.6% (84/151). Five patients accepted the re-operation intervention in the medium-term follow-up. The rest of the patients recovered well. Only 2 patients were classified as grade Ⅲ in cardiac function, and the rest patients were classified as gradeⅠ-Ⅱ. Conclusion    According to the degree of right ventricular hypoplasia, the age at operation and the presence or absence of coronary artery malformation, the individualized surgical strategy could significantly improve the success rate of PA/IVS, and early completion of right ventricular decompression operation is conducive to improve the chance for biventricular repair.
