Objective To investigate the features of female sexual dysfunction (FSD) in type 2 diabetic patients (T2DM)and to analyze its risk factors. Methods According to FSFI indexes in the sexual function questionnaire,227 female T2DM patients were divided into DM group without FSD [n=144,FSFI≥25] and DM+FSD group[n=83,FSFI<25]. 80 healthy women served as normal controls. The risk factors for FSD were analyzed using logistic regression analysis. Results The occurrence of FSD was 36.6%(83/227) in female T2DM patients. The levels of FSH,TSTO and LH were higher,and E2 was lower in DM+FSD group and DM group than those in NC group(P<0.01),but there was no statistical significance between DM+FSD group and DM group(P>0.05). The score of sexual desire[(2.54±0.58) vs (3.76±0.90) vs (4.59±1.22) score],sexual arousal[(2.30±0.42) vs (3.57±0.85) vs (4.81±1.00) score],vaginal lubricate[(3.35±0.29) vs (4.46±1.32) vs (5.14±0.83) score],orgasm[(2.75±0.68) vs (3.40±1.86) vs (4.02±1.25)score] and total score [(17.94±4.15) vs (24.71±6.33) vs (28.13±5.78) score] were lower in DM+FSD group and DM group than those in NC group. The score of sexual satisfaction[(3.45±1.68) vs (4.94±0.93),(4.99±0.86)score] and pain[(3.55±0.50) vs (4.58±0.47),(4.58±0.62)score] were lower in DM+FSD group than those in DM group and NC group(P<0.05),but there was no statistical significance between DM group and NC group(P>0.05). Logistic regression analysis showed that age,BMI and HbA1c were risk factors for FSD in T2DM patients (P=0.029,0.001,0.022,respectively). Conclusion The occurrence of FSD is common in female type 2 diabetic patients. BMI and HbA1c are the main risk factors for FSD.

The protection of ginseno-side (GNS ) isolated from leaves and stems on cultured cell from virus were observed. The results showed that GNS, especially the Rb1 monomer could suppress replication of virus such as HSV -Ⅰ , HSV-Ⅱ ,ADV- Ⅲ and VSV, and protect the cultured cells from virus infec-tion. A cream containing GNS was used in the treatment of herpes lebialis infected by HSV- I and 27 of 31 (87. 1%) cases were cured.

With the deepening of the clinical study,radiotherapy and chemotherapy are no longer single treatment,chemotherapy combined molecular targeted drugs,chemo-radiotherapy and some new treatment methods have been gradually recognized, and especially molecular targeted drugs began to establish its position in the treatment of tumor. Application of various methods individual or combined treatment can effectively prolong survival and improve the quality of life.

Objective:To retrospectively analyze the CT features among gastric cancer, gastric lymphoma and gastric malignant stromal tumors, evaluated the application value of MDCT in gastric malignant tumor.Methods: Sixty two patients with gastric malignancies tumor confirmed by pathology underwent MDCT plain scanning and triphasic contrasted scanning before operation. Referring to the pathological results, to observe the CT signs, include: scope of tumors and involvement, the density of tumors and enhanced characteristics, mucosal membrane, the change of the stomach softness, peripheral lymph node enlargement, the involvement of other organs, and to make statistical analysis for imaging features of these tumors byx2 testing.Results: Sixty two cases of gastric malignant tumor included 42 cases of gastric carcinoma, 12 cases of gastric lymphoma and 8 cases of gastric malignant stromal tumor, were confirmed by postoperative pathology. The CT manifestations were as follows: the stomach mucous membrane surface involvement in all the gastric cancer, the positive rate was significantly higher than gastric lymphoma and stromal tumor. The area involved by lymphoma were more than two partitions, significantly higher than that of gastric cancer and stromal tumor (x2=36.643,x2=20.00;P<0.05). 39 cases (92.8%) of gastric cancer and 8 cases (100%) of malignant stromal tumors were significantly enhanced, but all gastric lymphoma were not obvious enhancement. The positive rate of enlarged lymph nodes in gastric cancer(61.9%) and lymphoma(83.3%) were higher than stromal tumor(12.5%)(x2=9.731,x2=6.603;P<0.05).Conclusion: The CT manifestations of the gastric cancer, lymphoma, malignant stromal tumors had different characteristics. Multislice CT for the diagnosis and differential diagnosis of gastric malignant tumor has important value.
