Chinese Journal of Experimental Ophthalmology 2011;29(7):660-664
Retinocytoma is a benign tumor arising from the retina.Since it was first described by Gallie in 1982,retinocytoma has been progressively recognized.More and more clinical and pathological studies indicate that retinocytoma may be a early stage or a type of retinoblastoma.Retinocytoma is difficult to be found because of lack clinical signs.Therefore,it is very important for us to follow-up and screen the families of RB patient in order to intervene with the course of disease as early as possible for preventing and arresting the malignization of retinocytoma toward RB.The name alteration,clinical manifestations,histopathological features,molecular mechanism and heredity characteristics were reviewed.

Objective To explore the effect of Shenling Baizhu Powder and moxibustion on serum brain-gut peptide in patients with diarrhea predominant irritable bowel syndrome (D-IBS). Methods Sixty D-IBS cases were randomly divided into two groups, 30 cases in the treatment group were given Shenling Baizhu Powder and moxibustion therapy, and 30 patients in the control group were given loperamide hydrochloride capsule. Treatment for the two groups lasted for 4 weeks. Clinical symptoms and serum brain gut peptide (5-HT, VIP and SP) levels of two groups were observed before and after treatment, clinical efficacy were evaluated. Results Markedly effective rate of the treatment group was 66.7% (20/30), better than 33.3% (10/30) in the control group (P<0.05). After treatment, clinical symptom scores of the treatment group decreased significantly (P<0.01), while only diarrhea and abdominal pain improved in the control group (P<0.01), with statistical significance (P<0.01). After treatment, serum 5-HT, VIP, and SP of the treatment group were decreased (P<0.01), while these indexes of the control group did not change significantly (P>0.05), with statistical significance (P<0.01). Conclusion Clinical efficacy of Shenling Baizhu Powder and moxibustion in treating D-IBS is better than that of loperamide hydrochloride capsule, and can significantly improve clinical symptoms and regulate serum brain-gut peptides levels.
