Objective To study the anti-inflammatory and analgesic effects of Jingtongning Capsule. Methods Models of acute inflammatory reactions of croton oil-induced mouse ear edema and carrageenan-induced rat raw swelling and chronic inflammatory reaction of cotton ball-induced mouse granuloma in abdominal cavity were performed to study the anti-inflammatory effects of Jingtongning Capsule. Model of acetic acid-induced writhing in mice was used to study the analgesic effect of Jingtongning Capsule. Results Jingtongning Capsule significantly suppressed croton oil-induced mouse ear edema and carrageenan-induce rat paw swelling. Cotton ball-induced mouse granuloma in abdominal cavity was also markedly reduced by Jingtongning Capsule. The writhing times of mice induced by acetic acid were decreased by Jingtongning Capsule. Conclusions Jingtongning Capsule has obvious anti-inflammatory effect on acute and chronic inflammatory reactions. The pain reactions induced by chemical stimulus was significantly relieved by Jingtongning Capsule.

Objective To evaluate the efficacy and safety of pentoxifyline (PTX) on the treatment of collagen-induced arthritis in rats. Methods Wistar rat arthritis model was induced by bovine Ⅱ collagen (BⅡC) . The rats were randomly divided into four groups including normal control group, CIA control group treated with normal saline, indometaein group and PTX group. The body weight, the hind paw volumes, the arthritic index of all rats at different time points were observed and measured. At the end of the experiment, the radiographic changes and the synovial pathology score of rat ankle joints were evaluated to analyze the treatment role of PTX on CIA inflammation. Results The collagen-induced arthritis model was induced successfully at 11~13 days after first immunization with type Ⅱ collagen. After administration, the rat weights of PTX group were higher than that of CIA group (P<0.01) and no significant difference was found between PTX group and normal control group since week three. The degree of swelling of ankle joints in PTX group was decreased since the 17th day. At week five, the volumes of hind paw in PTX group and indometacin group was not different from that in normal control group (P>0.05). Compared with CIA group, the degree of synovial swelling of PTX group and indometacin group was decreased, synovial proliferation and inflammatory cell infiltrations was mild, and vascular hyperplasia and pannus was significantly declined. No cartilage erosion and necrosis was found. The pathological score of PTX group and indometacin group was significantly decreased(P<0.01). The parenchyma of ankle joint was swollen and no osteoporosis and bone erosion was found in PTX group and indometacin group. Conclusion PTX can ameliorate the symptoms and inhibit the swollen of rat arthritis. It is effective and with good safety profile.

Objective: To determine the rate of lymph node metastases in women with endometrial carci-noma and to compare the pattern of lymphatic spread of endometrial carcinoma with that of cervical carcino-ma. Methods: We retrospectively analyzed the lymphatic spread in 104 patients with endometrial carcinoma and 253 patients with cervical carcinoma. All of the patients underwent a complete pelvic and para-aortic lymphadenectomy from caudal to the median circumflex to the level of renal vessels. Results: The incidence of lymphatic metastases in the endometrial carcinoma group was higher than that in the cervical carcinoma group (22.1% vs 16.2 %). The pathologic grade (G_1: 12.1%; G_2: 21.4%; G_3: 34.5%) and depth of myometrial in-vasion (≤1/2: 11.9%; >1/2: 29%) were correlated with lymph node metastasis. The rates of para-aortic node involvement, pelvic lymph node involvement and involvement of both were 4.3%, 34.8% and 60.9% in the en-dometrial carcinoma group and 0%, 68.3% and 31.7% in the cervical carcinoma group. The rates of obturator node involvement were 73.9% and 70.7%, respectively; the rates of suprainguinal node involvement were 8.7% and 7.3%, respectively. Compared with cervical carcinoma, endometrial carcinoma showed higher rate of para-aortic and sacral node involvement (65.2% vs 31.7%, and 21.7% vs 17.1%) and lower rate of extamal iliac node involvement (17.4% vs 41.5%). Conclusion: Compared with cervical carcinoma, endometrial carcino-ma has a distinct lymphatic spread pattern and can directly metastasize to both pelvic lymph nodes and pa-ra-aortic lymph nodes with pelvic lymph node metastases being dominant. Positive lymph nodes are common-ly seen in cases of all pathological grades.
