Oncologic outcomes of surgical treatments of advanced sinonasal malignancies / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the prognoses of advanced (T3-T4) sinonasal malignancies (SNM). Methods: The clinical data of 229 patients with advanced (T3-4) SNM who underwent surgical treatments in the First Affiliated Hospital of Sun Yat-sen University from 2000 to 2018 were retrospectively analyzed, including 162 males and 67 females, aged (46.8±18.5) years old. Among them, 167 cases received endoscopic surgery alone, 30 cases received assisted incision endoscopic surgery, and 32 cases received open surgery. The Kaplan-Meier method was used to estimate the 3-year and 5-year overall survival (OS) and event-free survival (EFS). Univariate and multivariate Cox regression analyses were performed to explore significant prognostic factors. Results: The 3-year and 5-year OS were respectively 69.7% and 64.0%. The median OS time was 43 months. The 3-year and 5-year EFS were respectively 57.8% and 47.4%. The median EFS time was 34 months. The 5-year OS of the patients with epithelial-derived tumors was better than that of the patients with mesenchymal-derived tumors and malignant melanoma (5-year OS was respectively 72.3%, 47.8% and 30.0%, χ2=36.01, P<0.001). Patients with microscopically margin-negative resection (R0 resection) had the best prognosis, followed by macroscopically margin-negative resection (R1 resection), and debulking surgery was the worst (5-year OS was respectively 78.4%, 55.1% and 37.4%, χ2=24.63, P<0.001). There was no significant difference in 5-year OS between the endoscopic surgery group and the open surgery group (65.8% vs. 53.4%, χ2=2.66, P=0.102). Older patients had worse OS (HR=1.02, P=0.011) and EFS (HR=1.01, P=0.027). Patients receiving adjuvant therapy had a lower risk of death (HR=0.62, P=0.038). Patients with a history of nasal radiotherapy had a higher risk of recurrence (HR=2.48, P=0.002) and a higher risk of death (HR=2.03, P=0.020). Conclusion: For patients with advanced SNM, the efficacy of endoscopic surgery can be comparable to that of open surgery when presence of safe surgical margins, and a treatment plan based on transnasal endoscopic surgery as the main comprehensive treatment is recommended.

Progress on the antitumor activity of cryptotanshinone and its derivatives / 药学实践杂志

@#Objective    To share the experience of treating special cardiac malformations by applying minimally invasive techniques. Methods    Eight children with special cardiac malformations admitted to our hospital from July 2014 to September 2020 were recruited, including 3 males and 5 females, aged 0.8-1.2 (1.1±0.4) years, and weighted 7.8-11.5 (9.6±2.9) kg. There were 2 patients of huge muscular ventricular septal defect (VSD), 3 perimembranous cribriform VSD, 1 right coronary-right atrial fistula, 1 right coronary-right ventricular fistula, and 1 young, low-weight child with large aortopulmonary. All were treated with minimally invasive techniques using transesophageal echocardiography (TEE) as a guiding tool. All children received intraoperative TEE immediately to evaluate the curative effect of the surgery, and all went to outpatient clinic for reexamination of echocardiography, electrocardiogram and chest X-ray after discharge. Results    Eight children underwent minimally invasive surgery successfully without any incision infection, intracardiac infection, arrhythmia or pericardial effusion. None of the 8 children were lost to follow-up, and the results of all reexaminations were satisfactory. Conclusion    The application of minimally invasive techniques is a bold and innovative attempt for the treatment of a few special types of cardiac malformations. It has significant advantages in reducing trauma and medical costs in some suitable patients, and has certain clinical reference values.

Exploring the effects of entecavir treatment on the degree of liver fibrosis in patients with non-alcoholic fatty liver combined with chronic hepatitis B in Tibet region / 中华肝脏病杂志

Objective: To explore the efficacy of entecavir antiviral therapy on the degree of liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD) combined with chronic hepatitis B (CHB) in Tibet region. Methods: HBeAg-positive CHB patients who were treated with entecavir in the outpatient and inpatient Department of Infectious Diseases of the Tibet Autonomous Region people's Hospital between January 2018 to December 2019 were retrospectively analyzed. Among the 140 subjects with CHB, 95 cases were CHB alone, and the other 45 cases were diagnosed as CHB combined with NAFLD by ultrasound. All patients were given entecavir 0.5 mg orally once daily on an empty stomach for 48 weeks. HBeAg negative conversion rate, blood glucose, blood lipid, liver function and the degree of liver fibrosis were compared between the two groups at the 12th, 24th and 48th weeks of treatment to evaluate the virological response. SPSS 19.0 statistical software was used to process the data. Measurement data were expressed as mean ± standard deviation (x¯±s). Descriptive statistical analysis was used for t-test, and the categorical variables were expressed as percentage (%) and χ2 test. A p-value < 0.05 was considered as statistically significant. Results: After 48 weeks of treatment, the HBeAg and HBV DNA negative conversion rate were significantly better in patients with CHB alone (group B) than CHB combined with NAFLD (group A), that is to say, HBeAg negative conversion rate in group A and B patients were 28.90% and 40%, respectively, and group B was better than group A. HBV DNA negative conversion rate was significantly elevated in group B (83.2%) than group A (64.4%), with statistical significance (P<0.05), and the difference between the both groups was statistically significant. Alanine aminotransferase level was significantly decreased in patients with CHB alone than patients with CHB combined with NAFLD. Aspartate aminotransferase/platelet ratio index was significantly decreased after treatment than before treatment in both group of patients, and the depletion was more pronounced in CHB alone group. Liver stiffness values were significantly decreased in patients with CHB combined with NAFLD than CHB alone group. Moreover, liver stiffness values was higher in group A than group B before treatment under the influence of fat attenuation factors, and the differences before treatment and after treatment were 3.50±4.66 and 2.05±2.53, respectively; however, group B was not affected by fat attenuation factors, so LSM value reduction in group A was more obvious, and the differences were statistically significant. There was no statistically significant difference in blood glucose and blood lipids levels before and after treatment between the two groups. Conclusion: NAFLD has a certain effect on antiviral therapy and liver fibrosis in patients with CHB, i.e., the effect of antiviral therapy in patients with CHB alone is better than patients with CHB combined with NAFLD. Patients with CHB combined with NAFLD when treated with antiviral therapy had a significantly greater degree of liver stiffness reduction than patients with CHB alone. Therefore, it is necessary to actively intervene the risk factors associated with NAFLD according to the actual situation of different individuals to improve clinical efficacy of antiviral therapy.

Diagnosis and treatment of primary cardiac tumors in pediatric patients / 中华实用儿科临床杂志

Objective:To summarize the experience in diagnosis and treatment of primary cardiac tumors in pediatric patients.Methods:Retrospectively analyzing 7 pediatric patients who were suspected as primary cardiac tumors and diagnosed and treated in Department of Heart Center, Children′s Hospital of Dalian Medical University from August 2013 to February 2019.All patients underwent echocardiography and other examinations, so as to confirm the diagnosis and the treatment plan was chosen based on the size and location of the tumor.All patients were followed up after discharge.Results:A total of 7 patients were diagnosed as primary cardiac tumors by echocardiography, among which 5 cases underwent surgical treatment, and 2 cases were diagnosed with tuberous sclerosis without surgery.In children undergoing surgery, 1 patient underwent autologous heart transplantation to remove the tumor, 1 patient had arrhythmia, 1 patient had mitral regurgitation after surgery, and the mitral regurgitation was corrected again.The remaining children had no adverse complications and were discharged successfully.Histologic examination revealed rhabdomyoma in 4 patients, and fibroma in 1 patient.The patients were followed up for 2-66 months after discharge, and no tumor recurrence was observed in the children who performed surgery.There was a trend of spontaneously regress of cardiac tumor in 2 patients without surgery.Conclusions:Echocardiography is the first choice for the diagnosis of primary cardiac tumors in Pediatric patients.Rhabdomyoma is the most prevalent histologic type of primary cardiac tumors, and tuberous sclerosis should be excluded during the diagnosis process.Patients with tuberous sclerosis selected conservative treatment, and surgical treatment was selected for children with obvious symptoms.According to the location and size of lesion, therapy strategies should be chosen and autologous heart transplantation can be adopted to remove the tumor for children with large tumors.Autologous heart transplantation to remove the tumor is a good surgical treatment.

Analysis of the relationship between lifestyle habits and glycosylated hemoglobin control based on data from a Health Management Plan

BACKGROUND/OBJECTIVES@#Type 2 Diabetes mellitus (T2DM) is a hereditary disease that is also strongly dependent on environmental factors, lifestyles, and dietary habits. This study explored the relationship between lifestyle habits and glycosylated hemoglobin management in T2DM patients to provide empirical outcomes to improve T2DM management and patient health literacy. @*SUBJECTS/METHODS@#This study enrolled 349 diabetic patients with more than 5 care visits to a Diabetes Mellitus care network under the Health Management Plan led by Taiwan Department of Health (DOH). Based on relevant literature, an Outpatient Record Form of Diabetes Mellitus Care was designed and lipid profile tests were conducted for data collection and analysis. @*RESULTS@#When modeling the data, the results showed that the odds for HbA1c > 7.5% in T2DM patients duration over 10 years was 3.785 (P = 0.002) times that in patients with disease duration of fewer than 3 years. The odds of HbA1c > 7.5% in illiterate patients was 3.128 (P = 0.039) times that in patients with senior high school education or above. The odds of HbA1c > 7.5% in patients with other chronic illness was 2.207 (P = 0.019) times that in participants without chronic illness. Among 5 beneficial lifestyle habits, the odds of HbA1c > 7.5% in patients with 2 or 3 good habits were 3.243 (P = 0.003) and 3.424 (P = 0.001) times that in patients with more than 3 good habits, respectively. @*CONCLUSION@#This empirical outcome shows that maintaining a good lifestyle improves T2DM management and patients' knowledge, motivation, and ability to use health information. Patients with longer disease duration, education, or good lifestyle habits had optimal HbA1c management than those in patients who did not. Thus, effective selfmanagement and precaution in daily life and improved health literacy of diabetic patients are necessary to increase the quality of T2DM care.

Transthoracic echocardiography-guided percutaneous intervention for treatment of atrial septal defect complicated with pulmonary valvular stenosis in children / 中华全科医师杂志

Clinical data of 23 children with atrial septal defect and pulmonary valvular stenosis admitted in Dalian Children′s Hospital during March 2015 to March 2018 were retrospectively analyzed. Twenty patients were treated with percutaneous closure of atrial septal defect through femoral vein first, then transthoracic echocardiography-guided balloon pulmonary valvuloplasty was performed; while 3 patients had no balloon pulmonary valvuloplasty after percutaneous closure of atrial septal defect. Patients were followed up by transthoracic echocardiography and all were doing well. The transvalvular pressure fell under 35 mmHg (1 mmHg=0.133 kPa) [(19.5±1.9)mmHg] in all patients, which was significantly lower than that before treatment [(62.0±7.8 mmHg)] (t=28.92, P<0.01). During follow-up, no residual shunt of atrial septal defect was found; and mild pulmonary regurgitation occurred in 3 cases. The study indicates that combined percutaneous treatment with transthoracic echocardiography guidance is effective and safe for children with atrial septal defect and pulmonary valvular stenosis. The pulmonary artery stenosis of some patients can be alleviated, after closuring of the atrial septal defect.

Analysis of risk factors of severe hypocalcemia after total parathyroidectomy / 中华肾脏病杂志

Objective To analyze the incidence and risk factors of hypocalcemia after total parathyroidectomy without autotransplantation. Methods A total of 783 maintenance hemodialysis patients who underwent TPTX in the Second Affiliated Hospital of Nanjing Medical University from September 2008 to September 2017 were included in the study. The preoperative blood biochemical examination, preoperative iPTH, total mass of parathyroid gland (M) and postoperative iPTH and electrolyte results were collected. The incidence of severe hypocalcemia after TPTX were analyzed retrospectively. Binary logistic regression model was used to analyze the risk factors of severe hypocalcemia after TPTX. Results The age of 783 patients with TPTX was (46.90±10.78) years old, and the average dialysis age was (91.36±41.75) months. Postoperative severe hypocalcemia occurred in 235 cases (30.01％). Binary logistic regression analysis showed that higher preoperative blood iPTH (OR=7.56, 95％CI: 1.55-36.79, P=0.01), higher blood alkaline phosphatase (OR=36.71, 95％CI:14.75-91.36, P<0.01), blood phosphorus (OR=1.74, 95％CI: 1.11-2.71, P=0.02) and greater mass of resected glands (OR=1.18, 95％ CI: 1.06-1.31, P<0.01) were the risk factors for post-hypocalcemia. The higher preoperative serum calcium can reduce the risk of postoperative hypocalcemia (OR=0.02,95％CI: 0.01-0.07, P<0.01). Conclusions The incidence of hypocalcemia after TPTX treatment for SHPT is very high. Blood iPTH, alkaline phosphatase, phosphorus, and total mass of intraoperative parathyroid gland excision are the independent risk factors for severe hypocalcemia after surgery.
