OBJECTIVETo explore the effect of Jinwu Jiangu Recipe (JJR) on the expression of synovial cells' nuclear factor-kappaB (NF-kappaB) and serum interleukin 17 (IL-17) in collagen induced arthritis (CIA) rats.

METHODSTotally 60 Wistar rats were randomly divided into 6 groups, i.e., the blank control group, the model group, high, middle, and low dose JJR treatment groups, and the tripterygium control group, 10 in each group. Except rats in the blank control group, CIA model was established in rats of the rest 5 groups. Then they were treated from the 7th day of modeling. After 4 weeks of medication they were sacrificed, serum collected, and synovium of joints were isolated. The expression of serum IL-17 was detected in synovium of joints by enzyme linked immunosorbent assay (ELISA). And the expression of NF-kappaB/P65, Ikappabetaalpha and NF-KappaB/P50 were detected by Western blot.

RESULTSCompared with the blank control group, the serum IL-17 level increased in the model group (P <0. 01). Compared with the model group, the serum IL-17 level obviously decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.01). Results of Western blot showed, when compared with the blank control group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 were significantly enhanced in the model group (P < 0.01). Compared with the model group, protein activities of NF-kappaB/P65 and NF-kappaB/P50 significantly decreased in high and middle dose JJR groups and the tripterygium control group (P < 0.05, P < 0.01). All indices mentioned above were higher in the low dose JJR group than in the tripterygium control group (P < 0.05, P < 0.01).

CONCLUSIONJJR could lower the expression of serum IL-17 in CIA model rats, and inhibit protein activities of NF-kappaB/P65 and NF-kappaB/P50.

Rheumatoid arthritis of the knee is a common disease, but suppurative arthritis caused by Gemella morbillorum in the same joint is rare. We report a case of suppurative arthritis caused by Gemella morbillorum in a patient with rheumatoid arthritis. Because the infection symptoms was not typical, the diagnosis was delayed, and the delayed diagnosis and therapy led to a poor outcome of the patient.

BACKGROUNDThe aim of this study was to clarify the electrocardiographic characteristics of repetitive monomorphic ventricular tachycardia (RMVT) originating from the left ventricular outflow tract, and to describe the results of treatment with radiofrequency catheter ablation (RFCA).

METHODSRoutine 12-lead surface electrocardiography and electrophysiological studies were performed on 11 RMVT patients with no organic heart disease, who were subsequently treated with RFCA directed at targets identified by pace mapping.

RESULTSThe surface electrocardiogram QRS characteristics of RMVT included an atypical left bundle branch block and right axis deviation, with a low amplitude "rs" or "rS" pattern in lead I, an "rS" or "RS" pattern in V1, and a precordial R wave transition zone in V2 or V3. In 1 patient, a small S wave was observed in V5. Using pace mapping techniques, we selected the left coronary cusp as the ablation target. RMVT was eliminated in all 11 patients immediately after radiofrequency energy delivered. During a follow-up of 13 +/- 7 months, RMVT recurred in only 1 patient.

CONCLUSIONRMVT originating from the left ventricular outflow tract has specific electrocardiographic characteristics, and can be successfully and safely cured using RFCA directed at the left coronary cusp.

OBJECTIVEThe aim of the study is to explore the effect of NF-kappa B signal pathway in neonatal sepsis so as to provide the experimental base for corresponding clinical treatment of the sepsis, in which NF-kappa B is taken as the target.

METHODSThe sepsis model was established in newborn rats by giving Staphylococcus aureus subcutaneously: (1) The electrophoretic mobility shift assay (EMSA) was used to observe the activity of NF-kappa B in the lungs and the livers in newborn rats with Staphylococcus aureus sepsis. (2) Immunohistochemical method was used to observe the activity of NF-kappa B P56 in newborn rats with Staphylococcus aureus sepsis. (3) The anti-oxidant pyrrolidine dithiocarbamate (PDTC) was used to observe its effect on NF-kappa B activities of liver and lungs and on the activity of splenic NF-kappa B P56 in newborn rats with Staphylococcus aureus sepsis.

RESULTSIn newborn rats with Staphylococcus aureus sepsis, the NF-kappa B activity in lungs was enhanced at the 1st hour and reached to the peak level at the 3rd hour; then, it was weakened gradually and at the 24th hour faded away. The activity of the liver NF-kappa B was also activated and peaked at the 4th hour; then, it was gradually weakened and at the 24th hour faded away. The positive expression of splenic NF-kappa B P56 began to be intensified at the 1st hour (12.0 +/- 3.7), peaked at the 3rd hour (51.4 +/- 5.9) and showed insignificant differences at the 24th hour (3.4 +/- 1.4) as compared with the sepsis group. PDTC had an inhibitive effect on the activities of liver NF-kappa B and lung NF-kappa B and on the positive expression of splenic NF-kappa B P56 used in the dosage of 50-200 mg/kg. The larger the dosage was used, the more intensified inhibitive effect could be obtained. In the dosage of 200 mg/kg, the inhibitive effect was the most intensified.

CONCLUSIONS(1) In newborn rats with Staphylococcus aureus sepsis, the NF-kappa B of lungs, liver and spleen were activated, and all indicate a peak. (2) The anti-oxidant PDTC can inhibit NF-kappa B activity in a dose-effect fashion in newborn rats with Staphylococcus aureus sepsis.
