Analysis of the prevalence and related factors of primary hypertension among adolescents and children in the Taicang area.

Objective: To investigate the prevalence of hypertension in adolescents and children in the Taicang area and analyse related factors to provide a theoretical basis for the prevention and control of hypertension in this region.

Methods: A total of 1,000 students who were visited and surveyed in primary schools in the Taicang area in 2021 were selected for statistical testing using a cluster random sampling method, and a survey was conducted on their dietary habits. dietary habits, such as the consumption of meals that included protein-rich animal products, beans and dairy products, vegetables and fruits, salty foods and fried food, was taken into consideration, along with physical fitness indices, waist-to-height ratio and waist circumference.

Analysis on the MRI and BAEP Results of Neonatal Brain With Different Levels of Bilirubin.

Background: To explore whether there is abnormality of neonatal brains' MRI and BAEP with different bilirubin levels, and to provide an objective basis for early diagnosis on the bilirubin induced subclinical damage on brains.

Methods: To retrospectively analyze the clinical data of 103 neonatal patients, to conduct routine brain MRI examination and BAEP testing, and to analyze BAEP and MRI image results of the neonatal patients, who were divided into three groups based on the levels of total serum bilirubin concentration (TSB): 16 cases in mild group (TSB: 0.0-229.

[Expression and significance of nuclear factor-kappa B ligand and correlation factor in the tissue of otitis media with cholesteatoma].

Objective: To investigate the expressions of nuclear factor-kappa B ligand (RANKL), receptor activator of nuclear factor-kappa B(RANK)and osteoprotegerin (OPG) and the relation of RANKL with bone- erosion in human cholesteatoma tissue.

Method: Thirty cholesteatoma and twenty normal auditory canal skin specimens were investigated. The expressions of RANKL, RANK and OPG were examined by immunohistochemistry.

[Clinical study of combined approach of tympanoplasty and mastoidectomy with close technique].

Objective: To improve the surgery results and living quality of patients following the operation of the combined approach of tympanoplasty and mastoidectomy with close technique.

Methods: The clinical data and following-up results of 49 patients treated with combined approach of tympanoplasty and mastoidectomy with close technique and 82 patients treated with open mastoidectomy with tympanoplasty were retrospective analyzed.

Results: In the group treated with combined approach tympanoplasty, all patients got dry ear in 20 days and 31 patients' hearing level enhanced over 15 dB after the operation; but in the group treated with open mastoidectomy with tympanoplasty, only 13 patients got dry ear in 20 days and no patients' hearing level enhance over 15 dB after the operation.

[Cholesteatoma in petrous part of temporal bone].

Objective: To explore the clinic characteristic of petrous bone cholesteatoma.

Method: One case was treated by supra-labyrinth approach. 8 cases did by labyrinth-cochlea approach.
