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 The aim of the study is to investigate whether the progressive incremental exercise can induce the change in bone maximum force.Methods One hundred and seventy healthy SD rats,aged 3 months,were used as samples after adaptive exercise for one week,and then they were divided to a basic control group(C_0),8 control groups and 8 exercise groups according to the training duration(2W,4W,6W,8W,9W,11W,13W and 15W).Based on Bedford and our pre-study.the longest training duration of the rats was 15 weeks.The maximum force(F) of femoral bone and the 2nd lumbar vertebrae(L_2)were tested by three-point bending test and compressive test separately.Results It was shown that there was no pronounced difference in F of femoral bone between con trol groups and exercise groups.But significant differences in F of L_2 were found between the control groups and exercise groups(P<0.001).Conclusions Changes in different degree were found in the F of femoral bone and L_2 during the process of growth.The differential effects of incremental exercise on F were caused by the difference in training intensities and in the bone types.

Objective To assess the right ventricular (RV) performance in patients with type 2 diabetes mellitus (2-DM) by two-dimensional speckle tracking imaging (2D-STI),and to explore the clinical value of RV longitudinal strain and strain rate.Methods Thirty-seven patients with 2-DM only and thirtyone patients coexisting diabetes and hypertension (DM + HTN) were studied.Thirty-nine healthy age matched persons served as control subjects.In each patient a conventional two-dimensional echocardiography was performed and also an echocardiographic study with strain/strain rate imaging was studied.Analysis of RV longitudinal systolic strain were obtained in the apical four-chamber view of the RV for the assessment of the RV free wall(F-PLSS),interventricular septum (S-PLSS) and the global RV wall (G-PLSS).The entire RV longitudinal peak systolic strain rate (G-SRs),peak early-diastolic strain rate (G-SRe) and peak late-diastolic strain rate (G-SRa) were performed in the apical four-chamber view.Results Compared with controls,F-PLSS,S-PLSS,G-PLSS,G-SRs and G-SRe were decreased in 2-DM and DM + HTN (all P ＜0.01),with lower values in DM + HTN (P ＜0.05).In the patients coexisting diabetes and hypertension,G-SRa was significantly lower than those in the control group (P ＜ 0.05).Compared with 2-DM,this difference was not significant in controls and DM + HTN (P ＞0.05).Conclusions No matte the patients of 2-DM with or without hypertension,the early changes of RV dysfunction can be found by 2D-STI.Patients coexisting diabetes and hypertension may have worse RV dysfunction.

Objective To evaluate the value of CT and MRIin diagnosis of littoral cell angioma(LCA) of spleen.Methods CT and MRI findings the data of 6 patients with LCA were rospectively analyzed,and all patients were proved LCA of spleen by pathology.Then enhanced CT (n =4 cases) and MRI (n =2 cases) were performed.The imaging performance of LCA was observed,and its imaging features was summarized.Results None of patients showed obvious signs and symptoms of hypersplenism,4 cases were with splenomegaly.5 patients had a single lesion,only one had few lesions.There were not any calcification or envelopement of all the lesions.On CT,all lesions demonstrated distinct borders.The enhanced scan for low-density nodules demonstrated slow progressive enhancement.On MRI,all the LAC had well circumscribed borders,and demonstrated T1 · hypointense and T2-equal,hyperintense signals,and progressive enhancement on the post contrast images.Conclusion CT and MRI imaging of littoral cell angioma of spleen have special imaging characteristics,those particular findings is helpful in the diagnosis.

Objective To study the imaging features of sacroiliac joints(SIJ) in patients who were misdiagnosed as spondyloarthritis(SpA).Methods A total of 34 patients with chief complaint of back pain and misdiagnosed as SpA from January 2007 to April 2013 in Department of Rheumatology Chinese PLA General Hospital were enrolled.The imaging,clinical manifestations,laboratory examinations data were analyzed.Result The main reason for misdiagnosis as SpA was because of sacroiliitis presenting on imaging.The final diagnoses included 24 patients as SIJ infection,4 patients as neoplastic diseases,2 patients as metabolic bone diseases,2 patients as sacroiliac joint degeneration,1 patient as gout of sacroiliac joint,1 patient as diffuse idiopathic bone hypertrophy.For patients with infection,there were 10 patients receiving X-ray and 22 patients receiving CT of SIJ.However,5 and 7 patients had negative results respectively.These patients with infection had abnormalities in MRI including all with bone marrow edema,21 patients with erosion of bone and joint,22 patients with muscle involved.As to the patients with malignancies,SIJ CT scan appeared normal.Bone marrow edema and erosion in MRI were found in all neoplasm patients expect one as ependymoma.Adjacent muscles were involved in the patient with Ewing's sarcoma.Either X-ray or CT in other patients demonstrated obvious abnormalities,but only mild erosion of bone was found in MRI.Conclusion Bone marrow edema of SIJ in MRI represented not only in patients with SpA.Rheumatologists should analyze the clinical manifestations and laboratory examinations comprehensively in order to avoid the misdiagnoses.

Purpose To evaluate the relative bioavailability of a domestic sustained-release metformin tablets (SRM) compared against an immediate-release metformin tablets (IRM) using a multiple-dose,two-way crossover design after a single-dose study. Methods Eighteen healthy adult male volunteers,aged 18 to 22 years (mean,20 years),weighing 55 to 76 kg (mean,64 kg) and with height ranging from 166 to 180 cm (mean,173 cm),and blood glucose levels from 4.0 to 5.9 mmol/L (mean,4.3 mmol/L) participated in the study.The concentrations of metformin in plasma were determined using a ion-pair liquid chromatographic method. Results In single-dose study,the mean residence time (MRT),Tmax,and apparent elimination half-life (T1/2) for SRM were significantly longer and Cmax significantly lower than the corresponding values determined for IRM.The similar results were also demonstrated in multiple-dose study.The mean values of the relative bioavaibility of SRM compared with IRM in two administration ways were (85.95±0.97)% and (86.44±7.88)%,respectively.The single-dose and multiple-dose administration of the 90% confidence interval for the ratio of the logarithmic transformed AUC values of SRM over those of IRM were calculated to lie between 0.83 and 0.88,0.83 and 0.89,respectively,being within the acceptable bioequivalence limit of 0.80～1.25. Conclusion SRM was of the characteristic of sustained-release pharmacokinetics.The relative bioavailability for single dosing was similar to that of multiple dosing,and both of the administration ways demonstrated bioequivalence in absorption between SRM and IRM.

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.
