Objective To determine the monokine levels of serum and synovial fluid (SF) in patients with JSpAs and estimate the correlation between monokines and inflammatory indices.Methods Serum and SF monokines (IL 1?,IL 1?,IL 6,IL 8,IL 12 and TNF ?) were measured by sandwich ELISA in patients with JSpAs ( n =28) and healthy controls ( n =10).The correlation between serum monokines and inflammatory indeces and between both serum and SF monokine levels was analysed.Results Elevated serum level of IL 6 was found in patients with JSpAs as compared to healthy controls ( P

Objective To construct the luciferase reporter gene vector of cell division cycle 2 (Cdc2) gene promoter and determine its transcriptional activity. Methods Primers were designed based on human Cdc2 promoter sequence from UCSC software. Then Cdc2 promoter from human genome DNA was replicated. After pGL3-Basic vector and Cdc2 promoter were digested with restriction enzymes SacⅠand XhoⅠseparately, Cdc2 promoter was inserted into pGL3-Basic vector. The recombinant plasmid named pGL3-Cdc2-promoter was transiently co-transfected into U2OS cells with control vector pRL-SV40, and then the activity of dual luciferase was detected. Results pGL3-Cdc2-promoter was constructed successfully. The restriction analysis and sequencing proved the entirely correct sequencing results. The luciferase activity was higher in pGL3-Cdc2-promoter/pRL-SV40 group than that of pGL3-Basic/pRL-SV40 group (1.591 5±0.199 8 vs 0.049 9±0.010 4). Conclusion pGL3-Cdc2-promoter can be transcribed and activated in U2OS cells. This study provided an important basis for screening and evaluation of anticancer drugs.

Xueshuan Xinmaining tablet is a Chinese patent medicine for treating chest pain caused by blood stasis. It is widely used in clinical prevention and treatment of coronary heart disease. In order to understand the treatment effect of Xueshuan Xinmaining tablet in patients with coronary heart disease, we extracted electronic medical record data from 18 large hospitals nationwide. We matched the coronary artery disease patients with or without Xueshuan Xinmaining tablet treatment on gender, age, condition at admission and whether combined with cardiac insufficiency on a one to one ratio. After matching, both groups, patients using Xueshuan Xinmaining tablet (group A) and patients not using Xueshuan Xinmaining tablet (group B), ended up with 1,122 people. In order to evaluate the effectiveness of treatment, the endpoint of effective group was defined as "cure" and "better" while the endpoint of invalid group was defined as "invalid" and "death". Chi-square test showed a statistical significant difference (P < 0.05) between the two groups of patients with coronary heart disease, with a higher efficiency in Xueshuan Xinmaining group. Classic logistic regression analysis showed no statistical significant difference between the two groups on treatment outcome efficiency. Generalized boosted models (GBM) and propensity score (PS) weighted Logistic regression were then applied to balance 45 variables between the two groups. The results showed a regression coefficient greater than 0 and a statistical significant difference (P < 0.05) between the two groups. Based on the existing results of the analysis, we considered that coronary heart disease patients using Xueshuan Xinmaining tablet had a higher efficiency in clinical efficiency than the patients not using Xueshuan Xinmaining tablet. Since this study did not certainly eliminate all the possible confounders and patients from the hospitals included in this study were not yet well represent the overall situation of the source population, the study conclusion only provided drug use reference for clinical doctors for coronary heart disease. Large randomized controlled trials needs to be done for more reliable results to guide clinical rational and effective medication.

This study collected demographic data, past history, personal history, family history, dosage, solvent, combined medication information of adverse reaction cases from a prospective, multi center, large sample intensive hospital monitoring, and found the influencing factors with cross-tab analysis. The results showed that in the medication group of 19-45, patients with allergic histories had a higher proportion in ADR; in the medication group of 46-65, male patients with allergic histories had a higher proportion in ADR; indication and non-indication group, patients of 19-45 years old, with combined medications and allergy histories had a higher proportion in ADR; Non-indication medication group, patients with combined medication, higher concentration, out-instruction solvent and dosage, had a higher proportion in ADR. So, the ADRs of Shenfu injection were related to the history of drug allergy, and also related to the indication, dosage, solvent, concentration when it was used.

Objective To investigate the efficacy and safety of a schedule of 2 cycles' high-dose dexamethasone (HD-DXM) as an initial therapy in adults immune thrombocytopenia (ITP), and compare with conventional dose prednisone therapy. Method A total of 59 newly diagnosed ITP patients were divided into 2 groups randomly. In 30 patients ( Dexamethasone group), oral HD-DXM was administered at 40 mg/d for 4 consecutive days, repeated one week later, and then failed to maintain. In the remaining 29and then gradually tapered. Results For short-term efficacy, after 1 and 2 weeks of treatment, the response rate in Dexamethasone group was significantly higher than that in Prednisone group (50. 0% vs 24. 1%, P ＜0. 01; 73.3% vs 55.2%, P ＜0. 05 ), while 3 weeks later, there was no remarkable difference between the two groups(83.3% vs 68.9%, P ＞ 0. 05 ), though the response rate in Dexamethasone group remained higher. For long-term effect, at the end of the 2nd and 3rd months of follow-up, the relapse rate in Dexamethasone group was significantly lower than that in Prednisone group(24. 0% vs 40. 0%, P ＜ 0. 05;32.0% vs 65. 0%, P ＜ 0. 01 ), while at the end of the 1st month of follow-up, there was no significant difference( 16. 0% vs 20. 0%, P ＞0.05 ). In addition, it's well tolerated and no complications such as severe infection or Cushing syndrome were complained in Dexamethasone group. Conclusion HD-DXM possesses an advantage over conventional dose prednisone therapy in efficacy and safety.

Objective To evaluate DSA and MRI in diagnosing focal nodular hyperplasia(FNH) of the liver.Methods DSA and MRI findings in seven patients with pathologically-proved FNH were retrospectively analyzed.Selective hepatic arteriography with DSA,and both plain and dynamic contrastenhanced MR scans were performed in all patients.The imaging findings were retrospectively evaluated and analyzed.Results On DSA examination,all FNH lesions were hyper-vascular,which were characterized by thickened and tortuous feeding arteries.And the feeding arteries,after entering the lesions,branched off peripherally in a radiation pattern and the lesions were evenly dyed with sharp borders.In venous phase,hepatic vein drainage was demonstrated in 6 cases.On dynamic contrast-enhanced MRI,marked enhancement of the lesions was observed,which lasted until to delayed phase when the lesions still showed hyper-intensity or iso-intensity signals.Scar signal in the lesion's center was seen in three cases,which started to enhance at portal vein phase and maintained to delayed phase.Conclusion On DSA imaging,FNH lesions are characterized by thickened and tortuous feeding arteries that branch off peripherally in a radiation pattern after entering the lesions.And the hepatic vein drainage is also a common finding in venous phase.Dynamic contrast-enhanced MRI can well display the abnormal signal of the central scar of FNH.The combination use of DSA and MRI can effectively improve the diagnostic accuracy for FNH.
