OBJECTIVE:To observe the efficacy and safety of vitamin A acid combined with vitamin A,vitamin E,celecoxib in the treatment of oral leukoplakia. METHODS:104 patients with oral leukoplakia were randomly divided into control group(52 cases) and observation group (52 cases). Control group received 1 Vitamin A soft capsule,3 times a day+1 Vitamin E soft cap-sule,3 times a day+1 Celecoxib capsule,twice a day. Observation group additionally received 1 Vitamin A acid tablet,twice a day. 4-week was regarded as 1 treatment course,it lasted for 3 courses. Clinical efficacy,and leukoplakia number,maximum diam-eter of leukoplakia,immunoglobulin A(IgA),IgM,IgG before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the dif-ference was statistically significant(P<0.05). Before treatment,there were no significant differences in leukoplakia number,maxi-mum diameter of leukoplakia,immunoglobulin levels in 2 groups(P>0.05). After treatment,leukoplakia number,maximum diam-eter of leukoplakia,IgA and IgM in 2 groups were significantly lower than before,and observation group was lower than control group,IgG was significantly higher than before,and observation group was higher than control group,the differences were statisti-cally significant (P<0.05). And there was no significant difference in the incidence of adverse reactions in 2 groups (P>0.05). CONCLUSIONS:Vitamin A acid combined with vitamin A,vitamin E,celecoxib shows obvious efficacy in the treatment of oral leukoplakia,it can effectively reduce clinical symptoms,improve immune function,with good safety.

Osteoarthritis is a chronic disabling disease that tends to occur in middle-aged and elderly population, the main pathological characteristics are the dynamic imbalance between the synthesis and degradation of articular chondrocytes, extracellular matrix and subchondral bone. The occurrence and development is related to many factors. This article reviews the structure, the function and the interaction between α2-macroglobulins and a disintegrin and metallo-proteinase with throm-bospondin motifs in the development of osteoarthritis.

?AIM:To investigate the correlation between dry eye and different degrees of diabetic retinopathy ( DR ) in type 2 diabetic patients.?METHODS: In the cross-sectional study, 340 patients (340 eyes) with type 2 diabetes were enrolled. Tear film function tests including tear meniscus height, tear film breakup time ( BUT ) , fluorescein staining, Schirmer Ⅰtest were performed followed by surveying questionnaires about dry eye. Retinal status was evaluated by retinal color photography and indirect ophthalmoscopy exam with dilated pupils to evaluate DR and whether companied by macular edema.?RESULTS:The prevalence of dry eye was 49. 41%. The mean duration of diabetes in patients with dry eye was 11.15±7.07a, while 6.92±5.45a without dry eye(P<0.01). Dry eye had the positive correlation to the development of DR. The incidence of dry eye in people with mild nonproliferative diabetic retinopathy ( NPDR ) , moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR) was 1. 097 times, 1. 724 times, 2. 86 times and 5. 43 times respectively, compared with people without DR. The occurrence of dry eye in people with macular edema increased by 3. 697 times compared with people without macular edema.?CONCLUSION: Dry eye was more prevalent in people with type 2 diabetes. The incidence of dry eye increased gradually with the occurrence and development of diabetic retinopathy.

Xanthelasma palpebrum is the most common type of xanthoma that develops mainly on the inner epicanthus of upper eyelids with symmetrical distribution. The lesion tends to be permanent, progressive and cosmetically disfiguring. The recommended treatment has been surgical excision, local treatment with chemicals, and carbon dioxide laser. All of the mentioned treatment have some disadvantages including scarring, pigmentary change and need for local anesthesia. We describe the treatment of xanthelasma palpebrum with the pulsed dye laser which coagulates the hyperpermeable vessels so that the lipid leakage could be blocked and prevent recurrence and further progression.

Objective To analyzes the CT manifestations of pulmonary Langerhans cell histiocytosis (PLCH). Methods CT features of 11 patients with PLCH proved pathologically were analyzed retrospectively. Results The main findings in 11 PLCHs were cysts and nodules. Two cases only had cysts,and 1 only had nodules, which most had cavitations. The other 8 cases showed cysts and nodules with 4 cases mainly manifested with cysts and nine mainly manifested with nodules. Two cases had pulmonary interstitial changes. One case only had cysts in the left upper lung field and 10 cases had lesions not only in the upper and middle but in the lower lung field, which 2 cases had more lesions in the lower and costophrenic angle field and 8 cases had less lesions in the costo-phrenic angle field. Three of these 8 cases had more lesions in the superior lobe and apical segment of lower lobe. Conclusion CT manifestations of PLCH are helpful for the early diagnosis.
