RESUMO
@#Objective To analyze the epidemiological characteristics of mumps in Inner Mongolia Autonomous Region from2015 to 2022,and provide decision making strategy for the control and prevention of mumps.Methods Using SPSS 26.0and Excel 2010 statistical software,the epidemiological statistical description and analysis of mumps cases in Inner Mongolia Autonomous Region from 2015 to 2022 were performed.Results A total of 16 018 cases of mumps were reported in Inner Mongolia Autonomous Region from 2015 to 2022,with an average annual incidence of 8. 274 5/100 000. All cities had reported cases,and the peak incidence was mainly concentrated from April to July and from September to December. The age of the affected population was mainly 0-14 years old,accounting for 90. 14% of the total number of cases,and the affected population mainly included students,preschool children and scattered children.Conclusion From 2015 to 2022,the incidence rate of mumps in Inner Mongolia Autonomous Region showed a downward trend,and the average annual incidence was lower than the national reported level. The epidemic showed an obvious seasonality,and students,kindergarten children and scattered children were the key groups for prevention and control. It is necessary to strengthen the surveillance,prevention and control of mumps in schools,kindergartens and other collective units,and continue to implement the immunization strategy of age-eligible children vaccinated with two doses of mumps-containing vaccine(MuCV).
RESUMO
Objective @#To explore the main points of clinical treatment of fourth branchial cleft deformity in special positions and to provide a reference for clinical practice. @*Methods@#The clinical data of one case of a fourth branchial cleft deformity that occurred in the left anterior chest wall with a fistula below the clavicle are summarized and combined with a literature review.@*Results@# The patient complained of repeated swelling and pain under the left anterior chest wall for 2 months. A 10 mm×10 mm fistula with yellow clear liquid exudate from the fistula was observed on the left side below the clavicle. A 20 mm×20 mm×10 mm swelling was immediately adjacent at the superficial cervicothoracic junction of the upper sternoclavicular joint, with no fluctuation and poor activity; this swelling produced slight pain upon pressing. Imaging examinations pointed to cystic lesions. The primary diagnosis was a fourth branchial deformity. A small amount of methylene blue was injected into the patient's subclavian fistula, and a supraclavicular T-shaped incision was made where the cyst contacted the fistula. By turning the flap, all the methylene blue-stained areas and adjacent submucosal tissues were exposed. During the operation, a mass was found on the sternum. The platysma was found deep in the notch, which was incised before excising the surrounding area. The pathological result is the fourth branchial cleft deformity. After 1 week and 3 months of follow-up, the patients had no discomfort and no recurrence. A review of the relevant literature shows that the fourth branchial cleft deformity is a congenital developmental abnormality that occurs in 1% of all branchial cleft deformity. It often presents as a fistula, cyst, or sinus tract and is anatomically located at the neck root and supravicular region. The fistula is close to the medial lower boundary of the sternocleidomastoid muscle. The diagnosis is often made based on its anatomical location, imaging examinations and, ultimately, pathology. The differential diagnoses include other cervical swellings, such as hemangioma and a thyroglossal duct cyst. Surgical resection is a commonly used treatment method. In recent years, endoscopic positioning and internal fistula burning have had good curative effects for recurrent fourth branchial cleft deformity, with a small chance of recurrence or cancer.@* Conclusion @#Given its unique position, clinicians should make full use of imaging methods to determine the size, anatomical location and course of the lesion when treating the fourth branchial cleft deformity to ensure the complete and safe surgical resection of the lesion and prevent recurrence.
RESUMO
Objective@#To investigate the prevalence of high blood pressure in adolescent children and adolescents in Jiamusi, Heilongjiang Province, China. To analyze age , gender-and age* gender-spectific classification of blood pressure to height ratio for screening high blood pressure in adolescence.@*Methods@#Anthropometric parameters were measured in 26 068 Han students aged 10 to 17 participating in the routine physical examination in Jiamusi, Heilongjiang Province. Using the receive operating characteristic curve to determine the cutoffs for screening high blood pressure by three classification methods. The area under curve( AUC ), sensitivity, specificity, positive likelihood ratio (+ LR ), negative likelihood ratio (- LR ), positive predictive value (PPV ), negative predictive value ( NPV ), and Kappa value were used for evaluation.@*Results@#The detection rate of high blood pressure in children and adolescents was 22.7%. When screening high blood pressure in adolescence, the AUC , sensitivity, specificity, +LR, -LR, PPV, NPV , and Kappa values of the gender classification were 0.87, 95.0%, 79.1%, 4.56, 0.06, 57.2%, 98.2% , 0.60, respectively; the age classification were 0.89, 93.3%, 84.5%, 6.04, 0.08, 64.0%, 97.7%, 0.67, respectively; the age-gender classification were 0.90, 94.3%, 85.5%, 6.52, 0.07, 65.7%, 98.1%, 0.69, respectively. The sensitivity, specificity and negative predictive values of the three methods were higher, but the positive predictive value was lower. The age-gender classification had the highest AUC and Kappa value and the lowest were gender classification.@*Conclusion@#The age-gender classification has the best screening effect, but it is relatively complicated. The age classification has a good screening effect and it is more convenient. Both methods are recommended for screening for high blood pressure during puberty.
RESUMO
@#The main treatment of head and neck cancer is comprehensive sequential treatment, but the 5-year overall survival rate is less than 50%. Strategies to further improve the curative effect of head and neck cancer are urgently needed in the clinic. Recombinant human vascular endostatin is an antiangiogenesis drug targeting vascular endothelial cells, which has a certain inhibitory effect on tumors. The treatment of malignant tumors by drugs alone is not significantly better than chemoradiation, but combined with radiotherapy and chemotherapy, it can increase the effect of radiotherapy and chemotherapy without drug resistance by changing the distribution of blood vessels, reducing oxygen and normalizing blood vessels. Head and neck tumor treatment has certain advantages. New tumor treatments are expected. The results of a literature review showed that the mechanism of action of recombinant human endostatin mainly includes regulating the matrix protein inside and outside the endothelial cells to influence neovascularization, acting on receptors related to the surface of endothelial cells, reversing abnormal neovascularization to achieve vascular normalization, inhibiting hypoxia inducible factor to improve the hypoxic status of the tumor area, and regulating the cell cycle to ensure the tumor cells are sensitive to radiation in the sensitive period, and vascular normalization can increase the effect of radiotherapy. This treatment has a good synergistic effect with radiotherapy and chemotherapy of head and neck tumors and has a good effect on advanced head and neck tumors.
RESUMO
Objective@#To understand the needs of primary and secondary school students, parents and teachers for comprehensive sexuality education content, and to explore the applicability of comprehensive sexuality education content in China.@*Methods@#By using the method of stratified cluster sampling, 5 571 primary and middle school students and 4 835 parents from Beijing, Chongqing, Heilongjiang (Harbin and Jiamusi) and Hubei (Wuhan and Xiaogan) were selected for questionnaire survey. Depending on the physical health monitoring points of various provinces and cities, 176 sexuality education related teachers in nine regions were surveyed. The development of the questionnaire was based on the content framework of comprehensive sexuality education proposed in the International Technical Guidelines for Sexuality Education.@*Results@#Students had a higher demand for knowledge on the concepts of "relationship" (53.4% for primary school students, 57.6% for junior high school students) and "health and well-being skills" (71.1% for primary school students, 55.9% for junior high school students). Parents had higher demand for most comprehensive sexuality education content with the exception of lower need for "sex and sexual behavior (74.7% of primary school parents, 80.8% of junior high school parents)" and "sexual and reproductive health (primary parents 74.3%, junior high school parents 75.8%)". Teachers had a high demand for most comprehensive sexuality education content, but primary school teachers had a lower need for "values, rights, culture and sex(65.9%)", "sex and sexuality(60.1%)" and "sexual and reproductive health(66.8%)". The results of correspondence analysis showed that junior middle school teachers had the highest demand for comprehensive education content, followed by primary school parents, junior middle school parents, primary school teachers, junior middle school students and primary school students.@*Conclusion@#Teachers and parents have a higher demand for most comprehensive sexuality education content, while lower demand for some relatively sensitive content. Students have a relatively low demand for comprehensive sexuality education content. It is recommended to further improve the content of school sexuality education based on the actual needs of China.
RESUMO
Objective@#To understand the awareness of sexual knowledge among primary and secondary school students, as well as their attitudes towards school sex education and to provide a reference for school-based sex education.@*Methods@#A total of 5 531 primary and secondary school students were selected from Beijing, Chongqing, Heilongjiang (Harbin and Jiamusi) and Hubei (Wuhan and Xiaogan) by stratified cluster sampling and were investigated with self-reported questionnaire.@*Results@#Sex-related knowledge scored 62.33±19.35, with a pass rate of 61.9%, and the excellent rate 17.5%. Sexual knowledge of junior high school students scored 64.30±19.07, with the pass rate of 64.7%, and the excellent rate 22.0%. A large proportion of primary students reported unaware of pubertal growth and HIV/AIDS-related knowledge, and a large proportion of junior high students unaware of reproductive physiology. Multivariate Logistic regression analysis showed region, grade, gender, and suburban areas were related to the level of sexual knowledge(P<0.05). More than 76.0% primary students and 85.9% middle school students agreed on the importance of school sexuality education. 59.7% of primary school students and 73.3% of junior high school students hoped to include school sexuality education in compulsory education courses; 59.8% of primary school students and 68.3% of junior high school students felt that school sexuality education should be equipped with specialized teachers.@*Conclusion@#Chinese primary and secondary school students are lack of sexual knowledge. As students have strong wills to get more information on sexual knowledge, schools should provide them with more comprehensive and effective sex education through appropriate courses and activities.
RESUMO
ABSTRACT Objective: To evaluate the efficacy and safety of bipolar transurethral enucleation and resection of the prostate (B-TUERP) versus bipolar transurethral resection of the prostate (B-TURP) in the treatment of prostates larger than 60g. Material and Methods: Clinical data for 270 BPH patients who underwent B-TUERP and 204 patients who underwent B-TURP for BPH from May 2007 to May 2013 at our center were retrospectively analyzed. Outcome measures included operative time, decreased hemoglobin level, total prostate specific antigen (TPSA), International Prostate Symptom Score (IPSS), maximal urinary flow rate (Qmax), quality of life (QoL) score, post void residual urine volume (RUV), bladder irrigation duration, hospital stay, and the weight of resected prostatic tissue. Other measures included perioperative complications including transurethral resection syndrome (TURS), hyponatremia, blood transfusion, bleeding requiring surgery, postoperative acute urinary retention, urine incontinence and urinary sepsis. Patients in both groups were followed for two years. Results: Compared with the B-TURP group, the B-TUERP group had shorter operative time, postoperative bladder irrigation duration and hospital stay, a greater amount of resected prostatic tissue, less postoperative hemoglobin decrease, better postoperative IPSS and Qmax, as well as lower incidences of hyponatremia, urinary sepsis, blood transfusion requirement, urine incontinence and reoperation (P<0.05 for all). Conclusions: B-TUERP is superior to B-TURP in the management of large volume BPH in terms of efficacy and safety, but this finding needs to be validated in further prospective, randomized, controlled studies.

Abstract Objective There are a lot of disagreements in the studies on hepatitis B virus (HBV) DNA polymerase mutation rate associated with nucleos(t)ide analogues (NAs) in treatment-naive chronic hepatitis B (CHB) patients. This is the first study aimed to investigate the prevalence of spontaneous HBV resistance mutations in Central China. Methods This study included treatment-naive patients with CHB from June 2012 to May 2015 receiving care at the Institute of Liver Disease in Central China. All patients completed a questionnaire covering different aspects, such as family medical history, course of liver disease, medication history, alcohol use, among others. Mutations in HBV DNA polymerase associated with NAs resistance were detected using INNO-LiPA assay. Results 269 patients were infected with HBV genotype B (81.4%), C (17.9%), and both B and C (0.7%). Mutations in HBV DNA polymerase were detected in 24 patients (8.9%) including rtM204I/V (n = 6), rtN236T (n = 5), rtM250V (n = 2), rtL180M (n = 2), rtT184G (n = 1), rtM207I (n = 1), rtS202I (n = 1), rtM204V/I & rtL180M (n = 5), and rtM204I & rtM250V (n = 1). Conclusion Spontaneous HBV resistance mutations in HBV DNA polymerase were found in treatment-naive patients with CHB in Central China. These findings suggest that we should analyze HBV DNA polymerase resistance mutation associated with NAs before giving antiviral therapy such as lamivudine (LAM), adefovir (ADV), and telbivudine (LdT).
