1.Focal nodular hyperplasia: a review of new progress in the diagnosis and therapy
Chinese Journal of Hepatobiliary Surgery 2013;(6):473-476
Focal nodular hyperplasia (FNH) is one of the most common benign liver tumors.It has no potential for malignant transformation and an extremely low rate of rupture or hemorrhage.However,its nature and pathogenesis are still controversial.Accurately diagnosing atypical lesions of FNH based on clinical presentation and radiographic studies are still difficult.This review aims to analyze current literature of FNH and to discuss the new progress of pathologically and clinically relevant advice regarding diagnosis and management.
2.Diagnosis and treatment of verrucous laryngeal cancer--a case report.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2013;27(19):1092-1094
A male patient of 71 years old was admitted due to repeated hoarseness for two years which got worse accompanied with dyspnea so that to receive tracheotomy in another hospital more than one month ago. The two vocal cord biopsies carried out in the other hospital before showed vocal keratosis and squamous cell hyperplasia. Electronic laryngoscopy result showed normal epiglottis. a lot of saliva at hypopharynx, and rough arytenoid mucosa. The supraglottic area was remarkably swollen and the glottal area can not be observed clearly. The biopsy of throat was unable to conduct. Barium swallow examination revealed no obvious space-occupying lesion in piri form fossa or esophagus. Larynx CT scan showed a space-occupying lesion in the laryngeal cavity on the right side of the neck involving the thyroid cartilage. The patient was finally treated by total laryngectomy. cervical infected tissue resection. grafting transposition with pectoralis major flap and tracheostomy. The postoperative pathology showed laryngeal verrucous carcinoma.

Objective:Population-based cancer registration data were used to analyze stomach cancer epidemiology in China. Meth-ods:Stomach cancer data were retrieved from the National Central Cancer Registry Database, and incident and death cases were esti-mated. The trend of stomach cancer was analyzed. Results:Approximately 424,000 new cancer cases and 298,000 cancer deaths oc-curred in China in 2012. The incidence and mortality rates of stomach cancer in urban males and females remained stable in 2000-2012, whereas the rates in rural males increased and less changes were observed in rural females. After age standardization, both inci-dence and mortality rates significantly decreased. The five-year age-standardized relative survival rate was 27.4% (95%CI: 26.7%-18.1%) in 2003-2005. Conclusion:Stomach cancer is a common cancer, which has heavy burden in China, particularly in rural areas. Ef-forts should be exerted for the prevention and control of the disease.
