ABSTRACT
Bladder cancer (BC) is one of the most common malignancies of the urinary tract. Surgery combined with chemoradiotherapy is the mainstay of treatment, but BC is markedly heterogeneous, leading to unsatisfactory outcomes. Antibody-drug conjugate (ADC), a new type of targeted drug, has achieved remarkable results in the treatment of tumors by coupling a chemical junction with a highly cytotoxic small molecule, which can exert anti-tumor effects while avoiding the impacts on normal cells. To date, several ADCs have been used in the treatment of BC at home and abroad, and play an increasingly important role in the field of BC therapy. This article briefly introduces the mechanism of ADC, the current application of ADC in BC treatment, and the problems and challenges faced, hoping to provide reference for clinical work.
ABSTRACT
Female pelvic organ prolapse (POP) is caused by damage or loss of pelvic floor support, resulting in displacement of the pelvic organs, which leads to abnormalities in the position and function of the organs, mainly due to damage to the pelvic floor mechanical support structures caused by transvaginal birth, loss of elasticity of the pelvic floor mechanical support structures in old women, and loss of the ability to maintain the pelvic floor. The key to POP surgery is the repair of the apical vagina, but treatment based on this theory has failed to achieve satisfactory clinical outcomes. This article will analyze the common procedures of apical suspension in the treatment of mid-pelvic prolapse from the perspective of pelvic floor morphological features and pelvic floor biomechanics axially.
ABSTRACT
Objective:To analyze the whole genome of Omicron variants causing the first local Omicron outbreak in Henan Province and to investigate the mutations in the SARS-CoV-2 genome for source tracing.Methods:Respiratory tract samples from COVID-19 cases in the Omicron outbreak in Henan Province from January 7 to 29, 2022 were subjected to whole-genome sequencing and sequence alignment analysis. Whole-genome identity, variations and evolution of the Omicron variants were analyzed.Results:Through high-throughput sequencing, the whole-genome sequences of SARS-CoV-2 were obtained from 120 cases, which accounted for 25.64% (120/468) of all COVID-19 cases in Anyang during the same period. Compared with the genome of Wuhan reference strain (NC_045512.2), there were 57-59 nucleotide mutation sites in the 120 whole genome sequences, and one or two nucleotide mutation sites were added to the shared 57 nucleotide sites. All of the 120 strains were VOC/Omicron (BA.1.1) variants and shared high homology. The whole-genome sequence obtained from the first case A contained 57 nucleotide mutation sites, while apart from the 57 identical nucleotide mutation sites, one specific mutation site (C1594T) was found in the whole-genome sequence obtained from the first case B, suggesting that the two cases were in the same transmission chain. After comparing with the database of domestic and imported cases by the Chinese Center for Disease Control and Prevention and the Henan Provincial Center for Disease Control and Prevention, it was found that the current outbreak was linked with the same transmission chain as the existing local epidemics in other provinces. Moreover, epidemiological investigation showed that on January 2, case A had come into contact with her cousin and his family who returned from an affected area outside the province.Conclusions:Based on the gene sequencing results and epidemiological investigation, the COVID-19 outbreak in Anyang city, Henan Province was a local epidemic and the source of it was a college student who returned to Anyang city from other province on December 28, 2021. These infections were linked to the same transmission chain as the existing local infection in other provinces.
ABSTRACT
Despite the increasing number of patients was diagnosed with prostate cancer due to widespread cancer screening, PSA testing does not differentiate between lethal and slow-growing inert prostate cancers. This leads to a proportion of patients being over-diagnosed and consequently over-treated.The current study has found that PSA exists as a precursor to post-translational modification, and that [-2]proPSA originates only from the peripheral zone of the prostate. Furthermore, the study has shown that prostate health index (PHI) calculated from [-2]proPSA, fPSA, and PSA has a higher positive predictive value for prostate cancer, making it useful in the diagnosis of clinically significant prostate cancer. This article reviews the progress of research related to PHI in prostate cancer diagnosis and treatment.
ABSTRACT
ObjectiveTo investigate and analyze the knowledge, attitude and behavior of oral health for hemiplegic patients. MethodsFrom August 15 to September 15, 2019, patients with hemiplegia caused by central nervous system damages such as stroke and traumatic brain injury in Beijing Bo'ai Hospital were investigated their demographic information, oral health behavior, oral health knowledge, oral health attitude and utilization of oral health services through paper questionnaires. ResultsA total of 200 questionnaires were sent out and 184 valid questionnaires were collected. There were 103 patients with good brushing habits, and the highest proportion was in independent walkers (χ2 = 6.564，P = 0.038). The average score of oral health knowledge was 5.3, and the average accuracy of oral health knowledge was 75.7%. The average score of oral health attitude was 3.3, and the average positive attitude was 81.8%. Both the knowledge and attuite scores were not significant in different characteristics (Z < 5.299, P > 0.05). There were 59 patients visiting institute of stomatology in past twelve months, and there was no significant difference among genders and travel modes (χ2 < 4.707, P > 0.05). ConclusionThe brushing habits is well in independent walkers. The oral health knowledge and attitude of hemiplegia patients need to be improved, and the utilization of oral health services is low.
ABSTRACT
Silibinin is a kind of flavonoid extracted from the dried ripe fruit of Silybum marianum，a plant of compositae. It has a variety of pharmacological activities and can effectively prevent and treat diabetes and its complications. This paper reviews the research progress on the mechanism of silibinin in the prevention and treatment of diabetes and its complications. It is found that silibinin can prevent and treat diabetes by up-regulating the expression of estrogen receptor-α，activating the duodenum-brain-liver axis pathway and stabilizing the protein structure. It can prevent and cure the nervous system diseases of diabetes by activating glucagon-like peptide-1 receptor/protein kinase A signal pathway and inhibiting the hyperphosphorylation of tau protein. It can prevent and treat diabetic retinopathy by down-regulating the expression and activity of pro-inflammatory，pro-oxidative factors and histone deacetylase 6. It can prevent diabetic nephropathy by activating protein kinase B signal pathway and reducing the level of transforming growth factor-β1，and prevent and treat diabete’s obesity by inhibition of hepatobiliary transporter CD36 expression， and suppressing nuclear factor-κB pathway and its downstream expression of pro-inflammatory cytokines（tumor necrosis factor-α and interleukin-1β），etc.

ABSTRACT
Previous studies believe that oligometastasis has unique biological characteristics. Early active treatment for patients with oligometastatic prostate cancer can delay disease progression and improve survival. However, the current definition of oligometastasis is still unclear, and its optimal treatment is still a major concern of the medical community. This article reviewed recent research progresses in term of the definition and comprehensive treatment strategy of oligometastatic prostate cancer.
ABSTRACT
Bladder cancer(BC) ranks the first of genitourinary tumor in China and is one of the most common urological malignancies, in which 25%-30% of patients were diagnosed with muscle-invasive bladder cancer. Radical cystectomy combined with pelvic lymph node dissection is the standard procedure for treatment, which can effectively avoid tumor recurrence or distant metastasis as well as improve the prognosis of patients. However, some patients may not tolerate or refuse to undergo radical bladder surgery due to worry about high complication rate, high morbidity and poor postoperative quality of life. With the increasing understanding of bladder cancer heterogeneity and biological behavior, the treatment of bladder cancer has changed from a surgery-based treatment model to an individualized and comprehensive treatment model by multidisciplinary collaboration. The bladder-preserving treatment can achieve the same oncological prognosis as that of radical bladder surgery with a better quality of life of the patients, which has become a hot topic and focus of research in muscle-invasive bladder cancer treatment. This article reviewed the progress of research related to the comprehensive treatment of muscle-invasive bladder cancer with preservation of the bladder.
ABSTRACT
Objective To evaluate the clinical value of compound bone peptide injection in patients with thoracolumbar osteoporotic fracture. Methods 96 patients admitted from January 2018 to January 2020 with thoracolumbar osteoporotic fracture were selected. The patients were randomly divided into group A (receiving calcine D with compound bone peptide injection) and group B (receiving calcine D treatment) with 48 patients in each group. TCM symptom scores, bone metabolism, degree of osteoporosis, bone density level, visual analogue scale (VAS) and lumbar spine disease treatment score (JOA) were compared between the two groups after treatment. Results After treatment, the TCM symptom score and JOA score in group A were higher than those in group B (P<0.05). The levels of bone alkaline phosphatase (BALP) and type I procollagen N-terminal propeptide (PIINP) in group A were significantly lower than those in group B (P<0.05). The grade 3 osteoporosis ratio in group A was lower than that in group B (P<0.05). The bone mineral density level in group A was higher than that in group B (P<0.05). The visual analogue scale (VAS) in group A was lower than that in group B (P<0.05). Conclusion The treatment of thoracolumbar osteoporotic fracture with compound bone peptide injection effectively improved the bone metabolism and bone mineral density, relieved pain and promoted the recovery of lumbar function.
ABSTRACT
@#Objective To compare the clinical effects of segmentectomy and lobectomy for ≤2 cm lung adenocarcinoma with micropapillary and solid subtype negative by intraoperative frozen sections. Methods The patients with adenocarcinoma who received segmentectomy or lobectomy in multicenter from June 2020 to March 2021 were included. They were divided into two groups according to a random number table, including a segmentectomy group (n=119, 44 males and 75 females with an average age of 56.6±8.9 years) and a lobectomy group (n=115, 43 males and 72 females with an average of 56.2±9.5 years). The clinical data of the patients were analyzed. Results There was no significant difference in the baseline data between the two groups (P>0.05). No perioperative death was found. There was no statistical difference in the operation time (111.2±30.0 min vs. 107.3±34.3 min), blood loss (54.2±83.5 mL vs. 40.0±16.4 mL), drainage duration (2.8±0.6 d vs. 2.6±0.6 d), hospital stay time (3.9±2.3 d vs. 3.7±1.1 d) or pathology staging (P>0.05) between the two groups. The postoperative pulmonary function analysis revealed that the mean decreased values of forced vital capacity and forced expiratory volume in one second percent predicted in the segmentectomy group were significantly better than those in the lobectomy group (0.2±0.3 L vs. 0.4±0.3 L, P=0.005; 0.3%±8.1% vs. 2.9%±7.4%, P=0.041). Conclusion Segmentectomy is effective in protecting lungs function, which is expected to improve life quality of patients.
ABSTRACT
The rapid development of point-of-care testing (POCT) in clinical laboratories has brought challenges to the unified management in the hospital. There are many problems, such as how to ensure the ability and qualification of POCT operators, how to improve the quality management awareness of human, machines, materials, methods and environment in the process of POCT in clinical laboratories, how to help the clinical laboratories in the hospital to carry out POCT comparison, and how to strengthen the information construction of POCT in the hospital. Thus, this article reviews the practice and experience of POCT management in our hospital on POCT quality assurance and the problems existing in POCT in clinical departments, proposes suggestions and solutions to strengthen the unified management of POCT in clinical laboratories and establish POCT quality management documents and to improve quality awareness. We hope to provide references for hospital administrators, medical departments, nursing departments, quality control departments and other functional departments on the quality management of POCT in the hospital, and find helpful answers to the puzzles of clinical laboratory in POCT, so as to make joint efforts to standardize the quality management of POCT in the hospital to ensure the accuracy of testing results.

With the progress of research, exosomes derived from bladder cancer have shown great potential in the early diagnosis and treatment of bladder cancer. This article reviews the main biological characteristics of exosomes and their new developments in the diagnosis and treatment of bladder cancer.
ABSTRACT
@#Objective To investigate the effectiveness and safety of esophageal ultrasound-guided percutaneous femoral artery closure of ventricular septal defect (VSD). Methods The clinical data of 24 patients with congenital VSD in our hospital from March 2017 to December 2019 were retrospectively analyzed, including 6 males and 18 females, with a median age of 12 (3-42) years, weight of 32 (12-91) kg, and VSD diameter of 4 (3-7) mm. There were 3 patients with VSD combined with atrial septal defect. Results Twenty-four patients successfully underwent interventional closure of percutaneous femoral artery under esophageal ultrasound guidance, and the position and shape of the occluders were good. The operation time was 45 (39-54) min, and the waist size of the occluders was 7 (5-12) mm. Among the patients, 14 patients used symmetric ventricular occlusion devices, 8 patients used asymmetric ventricular occlusion devices, and 2 patients used ventricular occlusion muscle occluders. Small amount of residual shunt occurred in 2 patients after the operation and it disappeared 3 months after the operation. One patient with right bundle branch block, which disappeared after 1 week of observation. There were no complications such as occluder closure, pericardial effusion or valve regurgitation during the perioperative period. During the follow-up period [3-18 (9.25±5.04) months], no serious complication occurred. Conclusion Transesophageal ultrasound-guided transfemoral artery occlusion for VSD is simple and safe, and it avoids the damage of radiation and contrast medium. It has advantages over traditional percutaneous interventional occlusion therapy.
ABSTRACT
@#Objective To investigate the clinical efficacy and application value of percutaneous interventional treatment for structural heart diseases under guidance of ultrasound. Methods The clinical data of 1 010 patients with structural heart diseases treated by transcutaneous ultrasound-guided occlusion in our hospital from December 2, 2015 to December 31, 2019 were retrospectively reviewed, including 360 males and 650 females, aged 1-50 years. There were 692 patients of atrial septal defect (603 with central type, 9 combined with arterial catheter, 80 with ethmoid type), 116 patent foramen ovale, 25 ventricular septal defects (3 combined with atrial septal defect), 132 patent ductus arteriosus, 32 pulmonary valve stenosis (3 combined with atrial defect), 1 main pulmonary artery window, and 3 aneurysm rupture of aortic sinus. All patients were diagnosed by transthoracic echocardiography (TTE) before operation. Treatment was accomplished intraoperatively through TTE or transesophageal echocardiography (TEE) via the femoral artery or femoral vein. After operation, echocardiography, electrocardiogram and chest radiograph were reexamined. Results Satisfactory results were obtained in 1 005 patients, and 1 patient failed to seal the ventricular defect and was repaired under direct vision, occluder detachment occurred in 5 patients after operation (3 patients of atrial septal defects underwent thoracotomy for Amplatzer device and were repaired, 1 patient of atrial septal defects was closed after removing Amplatzer device, 1 patient of patent ductus arteriosus underwent thoracotomy for Amplatzer device and was sutured), mild pulmonary valve regurgitation occurred after balloon dilation in 2 patients with pulmonary stenosis, a small amount of residual shunt was found in 2 patients with ventricular defect, which disappeared after 3 months of follow-up, and 1 patient of right bundle branch block occurred and disappeared after 1 week. After follow-up of 1-24 months, 3 patients of ethmoidal atrial septal defect were reexamined with mild shunt. The occluder was in good position and the pressure difference of pulmonary valve was significantly reduced. There was no complication such as hemolysis, arrhythmia, embolism or rupture of chordae tendinae. Conclusion Percutaneous transfemoral artery and vein guided by TTE or TEE is safe and effective, with little trauma, no radiation or contrast agent damage, and has significant clinical efficacy and application values.
ABSTRACT
Objective:To summarize the experience of Bacillus Calmette-Guerin(BCG) in the treatment of bladder cancer secondary to renal transplantation.Methods:The clinical data of 5 patients who underwent BCG bladder irrigation after secondary bladder cancer after kidney transplantation in Tianjin First Central Hospital from January 2015 to December 2019 were analyzed. There were 1 male and 4 female cases. During the period of immunosuppression after transplantation, 1 case developed secondary high-level non-muscular invasive bladder cancer (NMIBC), 3 cases developed secondary low-grade NMIBC, and 1 case developed secondary glandular cystitis (4 cases). The mean age of the 5 patients with secondary bladder cancer was 59.7±4.0 years. Case one with high level NMIBC was treated with transurethral resection of bladder tumor (TURBT) and postoperative irrigation of epirubicin. Case 3 and 5 with low-level NMIBC accepted regular postoperative irrigation of gemcitabine. No irrigative therapy was performed in case 2. Bladder cancer recurred in case 1, 2, 3 and 5 after 20.1±9.7 months. TURBT was observed in all the 4 patients, among which 3 were of high grade NMIBC and 1 was of low grade NMIBC. Four patients were irrigated with BCG 2 weeks after operation. Postoperative pathology indicated low-level NMIBC in case 4, and BCG was irrigated 2 weeks after the operation. During perfusion therapy, immunosuppressive agents were continued.Results:During BCG perfusion, 4 of the 5 cases showed BCG related local inflammation, among which 2 cases presented symptoms of bladder irritation, 1 case presented hematuria, and 1 case presented hematuria with low fever. Patients with frequent urination, pain in urine, hematuria and other symptoms improved after drinking plenty of water, taking bed rest and taking levofloxacin (0.5g/ day ×7 days). Patients with low fever were treated with antipyretic treatment. No antituberculous agents were used prophylactically during BCG perfusion. There were no symptoms of tuberculosis infection or sepsis. The function of transplantated kidney was normal and no tendency of rejection. The 5 patients were followed up for 7-24 months, 1 patient was lost to follow-up after 7 months of BCG bladder perfusion, and no tumor recurrence or metastasis was found in 5 patients during the follow-up.Conclusions:The use of immunosuppressive agents does not reduce the biological activity of BCG, and BCG does not increase the risk of systemic toxicity or affect the function of transplanted kidneys in immunocompromised patients. BCG is a treatment option for bladder cancer secondary to renal transplantation.
ABSTRACT
Objective:To investigate the short-term efficacy of thoracoscopic radical surgery in the treatment of esophageal cancer and its influence on the expression of trigger receptor-1 (TRE-1) and tumor necrosis factor receptor-associated protein 1 (TRAP1).Methods:A total of 68 patients with esophageal cancer who were admitted to First People′s Hospital of Ningyang from June 2016 to June 2019 were selected and divided into thoracoscope radical surgery group and raditional surgery group by stratified sampling method, with 34 cases in each group. The thoracoscopic radical surgery group was treated with thoracoscopic radical surgery, and the traditional surgery group was treated with traditional open radical esophageal cancer surgery with neck, chest, and abdominal incisions. The levels of inflammatory factors, immune function, lung function indexes, TREM-1, TRAP1 expression and complications of the two groups were observed and compared.Results:Before operation, the levels of inflammatory factors tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 in two groups had no significant differences ( P>0.05). At 2 d after operation, the levels of TNF-α, IL-6, IL-10 in two groups were increased and the levels of above index in the thoracoscopic radical surgery group were lower than those in the traditional surgery group: (23.21 ± 0.32) mg/L vs. (29.69 ± 0.48) mg/L, (232.15 ± 23.64) ng/L vs. (246.73 ± 25.89) ng/L, (0.64 ± 0.19) ng/L vs. (0.89 ± 0.21) ng/L, and there were statistical differences ( P<0.05). Before operation, the levels of CD 3+, CD 4+, CD 8+, and CD 4+/CD 8+ in two groups had no significant differences ( P>0.05). At 2 d after operation, the levels of CD 3+, CD 4+, CD 8+ decreased and the level of CD 4+/CD 8+ increased, and the levels of CD 3+, CD 4+, CD 8+, CD 4+/CD 8+ in the thoracoscopic radical surgery group were higher than those in the traditional surgery group: (46.78 ± 1a2.43)% vs. (41.32 ± 9.36)%, (46.12 ± 9.68)% vs. (41.59 ± 7.98)%, (27.42 ± 4.27)% vs. (21.38 ± 3.16)%, 1.47 ± 0.46 vs. 1.25 ± 0.27, and there were statistical differences ( P<0.05). Before operation, the levels of forced expiratory volume in one second (FEV 1), forced vital capacity (FVC), FEV 1/FVC in two groups had no significant differences ( P>0.05). At 2 day after operation, the levels of FEV 1, FVC, FEV 1/FVC in two groups decreased, and the levels of FEV 1, FVC, FEV 1/FVC in the thoracoscopic radical surgery group were higher than those in the traditional surgery group: (2.37 ± 0.72) L vs. (1.82 ± 0.53) L, (3.34 ± 1.06) L vs. (2.43 ± 0.82) L, (62.47 ± 15.26)% vs. (53.67 ± 12.28)%, and there were statistical differences ( P<0.05).Before operation, the expression of TREM-1 and TRAP1 in two groups had no significant differences ( P>0.05). At 2 d after operation, the expression of TREM-1in the thoracoscopic radical surgery group was higher than that of traditional surgery group: (141.56 ± 34.69 vs. 121.54 ± 22.75); the expression of TRAP1 was lower than that of the traditional surgery group: (1.63 ± 0.51 vs. 2.11 ± 0.64), and there were statistical differences ( P<0.05). The postoperative complication rate of the thoracoscopic radical surgery group was lower than that of the traditional surgery group:5.88%(2/34) vs. 23.53%(8/34), and there was statistical difference ( χ2=4.221, P=0.040). Conclusions:The short-term efficacy of thoracoscopic radical surgery in the treatment of esophageal cancer is better than that of the traditional surgery group, which can increase the expression of TREM-1, reduce the expression of TRAP1, and reduce the inflammatory response and the impact on the immune function.
ABSTRACT
Objective:To provide data support for the prevention and control of dengue fever in Henan Province by analyzing the molecular epidemiological and etiological characteristics of dengue fever outbreaks in Puyang in 2019.Methods:Blood samples were collected from all suspected cases of dengue fever. The antigen, antibody and nucleic acid of dengue virus (DENV) were detected. The E gene was amplified by viral nucleic acid extraction and sequenced. Phylogenetic tree was constructed to trace the source of infection. Results:A total of 61 local cases of dengue fever were reported, and no deaths were reported. Among them, 4 cases (72.13%) were positive for DENV NS1 antigen; 16(26.23%) cases were positive for specific IgM; 38(62.30%) cases were positive for specific IgG; 34 cases (54.10%) were positive for dengue nucleic acid testing. Ten dengue virus strains were isolated, all of which were dengue virus type 1(DENV-1). Sequence analysis of E gene suggested it belonged to the same clade as Henan201903 strain imported from Cambodia to Zhumadian, Henan in 2019, with the highest homology. Conclusions:The dengue fever epidemic in Henan Province was caused by DENV-1, which might be improted from Cambodia, Singapore, Myanmar and other Southeast Asian countries. Therefore, the surveillance of DENV in people returning from Southeast Asia should be strengthened.
ABSTRACT
Objective:To analyze the clinical value of different doses of recombinant human brain natriuretic peptide (rhBNP) in the treatment of acute decompensated heart failure (ADHF) combined with renal insufficiency.Methods:Eighty patients with ADHF combined with renal insufficiency admitted to Jiaxing Second Hospital from December 2018 to January 2020 were selected. According to the random number table method, they were divided into A, B group, with 40 cases in each group. Two groups were treated with the conventional anti heart failure combined with rhBNP. The rhBNP loading doses of A and B group were 0.1 μg/kg. Group A was continually given rhBNP 0.01 μg/(kg·min) for 24 h after the loading dose, while group B was continually given 0.015 μg/(kg·min) rhBNP for 24 h. The efficacy of the two groups was compared, changes of systolic blood pressure (SBP), diastolic blood pressure (DBP), respiratory frequency (RR), heart rate (HR) and the degree of dyspnea of patients before and after the medication were monitored, and changes of serum creatinine (Scr), Cystatin C (Cys-C), left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), N-terminal pro B-type natriuretic peptide (NT-proBNP) and other cardiorenal function indexes of patients were determined. The changes of 24 h urine output were calculated, estimated glomerular filtration rate (eGFR) was counted, and the occurrence of adverse reactions and the incidence of major cardiovascular adverse events in the last 4 weeks in the two groups were observed.Results:There was no significant difference in the efficacy classification between group A and group B ( P > 0.05). After 24 h of administration, the scores of HR and dyspnea in group B were lower than those in group A [(83.86 ± 4.75) times/min vs. (86.52 ± 5.77) times/min, (1.52 ± 0.43) points vs. (1.89 ± 0.34) points] ( P<0.05). At the end of the treatment, the level of LVEF in group B was higher than that in group A [(47.52 ± 5.41)% vs. (43.75 ± 4.53)%], and the level of NT-proBNP was lower than that in group A [(3 652.41 ± 462.56) ng/L vs. (3 986.57 ± 314.21) ng/L] ( P<0.05). At the end of the treatment, the level of Scr of the two groups decreased and 24 h urine output increased, but there was no statistically significant difference between the two groups ( P>0.05). There was no statistically significant difference in the incidence of adverse reactions and adverse cardiovascular events between groups A and B ( P>0.05). Conclusions:0.015 μg/(kg·min) rhBNP maintenance therapy is more effective in improving cardiac function compared with that of 0.01 μg/(kg·min) maintenance doses in the treatment of ADHF combined with renal insufficiency, and it is safe and feasible without aggravating renal impairment of patients.
ABSTRACT
@#Objective To analyze the efficacy and safety of percutaneous balloon pulmonary valvuloplasty (PBPV) for pulmonary valve stenosis guided by ultrasound. Methods From March 2016 to July 2019, 32 patients with pulmonary valve stenosis were treated in our hospital. There were 19 males and 13 females with an average age of 1-12 (6.2±3.1) years and weight of 7-45 (22.7±9.2) kg. The clinical efficacy of PBPV guided by transthoracic echocardiography (TTE) was evaluated. Results The transvalvular pressure gradient (PG) of the patients before PBPV was 65.4±11.9 mm Hg. All patients successfully received PBPV under TTE guidance. The PG was 19.7±4.0 mm Hg immediately after operation, which was significantly decreased (P<0.001). All patients survived without any serious complications. The PG values at 3 months, 6 months and 12 months after operation were 18.4±4.0 mm Hg, 16.4±3.9 mm Hg, 15.2±3.3 mm Hg, respectively, which were significantly lower than that before the operation (P<0.001). Conclusion PBPV guided by echocardiography is safe and effective in the treatment of pulmonary valve stenosis with low complications rate.
