Objective To investigate the clinical efficacy of electroacupuncture at specific points in treating different degrees of urgency-frequency syndrome. Methods Sixty patients with urgency-frequency syndrome were randomly allocated, according to the symptom score, to groups A (the symptom score≤ 24) and B (the symptom score>24), 30 cases each. Both groups received electroacupuncture at specific points (four sacral points and four abdominal points). In the two groups, the symptoms were scored before and after treatment and the clinical therapeutic effects were evaluated.Results There was a statistically significant pre-/post-treatment difference in the symptom score in the two groups (P<0.01). The total efficacy rate was 83.3% in group A and 80.0% in group B; there was no statistically significant difference between the two groups (P>0.05).Conclusion Electroacupuncture at specific points is an effective way to treat urgency-frequency syndrome.

One hundred and seventy one gastric biopsy specimens from the patients undergoing gastroscopic examination from March to November 2010 were reviewed . HE, sliver and immunohistochemistry stains were performed in the specimens; the correlation of histopatholigy and the density and distribution of Helicobacter pylori in gastric mucosa was analyzed .The results displayed that spiral H.pylori mainly appeared on the surface mucus and in the gland lumen of gastric small concave , some were attached to the epithelial cells; coccoid H.pylori appeared within the apical cytoplasmic part of the epithelial cells and in the mucous membrane stroma .The depth of H.pylori infection was correlated with mucosal erosion , inflammation activities and amount of interstitial lymphocytes .The results suggest that spiral H.pylori infection may facilitate the invasive depth of coccoid H.pylori in gastric mucous membrane and the density of H.pylori infection is correlated with the extent and severity of inflammation .

Objective To analyze antimalarial assosiated retinopathy detected by different methods with of modern ocular fundus examination, and explore screening strategy and the diagnosis of hydroxych-loroquine assosiatedretinopathy according to clinical experience and international guidelines. Methods Full fundus examination was performed in two patients with antimalarial retinopathy. The related literature were reviewed. Results Two patients had bull's eyes maculopathy and abnormal visual fields. Conclusion Clin-icians' alertness to hydroxychloroquine related retinopathy may improve early diagnosis of hydroxychloroquine toxicity. New objective tests are more sensitive than visual fields examination. Visible bull's-eye maculopathy is a late change, and the goal of screening is to recognize toxicity at early stage.
