2.Local recurrence of rectal carcinoma: diagnosis and treatment
International Journal of Surgery 2009;36(11):789-792
Rectal carcinoma is a common malignant tumor in China. Although it decreased greatly after the introduction of total mesorectal excision and preoperative radiotherapy, the local recurrence rate of rectal carcinoma after curative surgery is still up to 11.3%. Surgery is the most effective treatment for local recurrence of rectal carcinoma. If excised radically, the five-year survival of patients with rectal carcinoma could be more than 35%. Only a few patients will benefit from ex-tended radical surgery because of its extremely high postoperative morbidity and mortality. Strict selection of patients by mul-tiple preoperative examinations makes extended radical surgery more reasonable. For the unresectable advanced recurrent rectal carcinoma, multimodality palliative therapy could lead to symptom relief, elevated quality of life and prolonged surviv-al. We discuss the diagnosis and treatment of recurrent rectal carcinoma in this review.
3.Clinical Experiences of Professor Zhang Qi in Treatment of Recurrent Urinary Tract Infection
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(8):1802-1804
Recurrent urinary tract infection (RUTI) is a common disease in China. Modern medicine usually treats it with antibiotics. However, the drug resistance and adverse reaction of antibiotics lower the therapeutic effects and the compliance of patients. Based on the overall concept of Chinese medicine and the relationship of pathogenic factors and vital qi, Professor Zhang Qi proposed the general principles of RUTI treatment according to its different phases and patterns. The principles are listed as follows, eliminating method was used in the treatment of excess pattern;invigorating method was used in the treatment of deficiency pattern; and promoting of body resistance and eliminating pathogenic factors method was used in the treatment of the deficiency-excess complex pattern. These principles have instructional significance for clinical application.

6.The research progress of galactose-deficient IgA1 in the related kidney diseases
Journal of Clinical Pediatrics 2014;(5):489-491
In recent years, IgA nephropathy and Henoch-Sch?nlein purpura nephritis attract more and more attention on their unclear pathogenesis, single diagnostic criteria, long duration and poor prognosis, etc. Research suggests that IgA nephropathy and purpura nephritis are IgA immune complex related diseases, and serum galactose-deficient is elevated in patients with these two dis-eases, which might become a noninvasive biomarker for the diagnosis, prognosis prediction and disease development monitoring for IgA nephropathy and purpura nephritis. Galactose-deficient IgA1 is reviewed for its discovery, structure, process, the possible patho-genic mechanism and its significance in details in this paper.
