Objective To evaluate the efficacy and safety of dorsal ligament reconstruction in treatment of old dorsal dislocation of distal radioulnar joint.Methods Seven patients with old dorsal dislocation of distal radioulnar joint were treated with dorsal ligament reconstruction using the palmaris longus tendon from March 2005 to May 2012 in our institute,including 4 males and 3 females with a mean age of 37 years.All patients had a history of wrist injury for more than 3 months and were diagnosed as isolated dislocation of distal radioulnar joint without fractures.During the operation a bone tunnel was made at dorsal ulnar side of radius near the ulnar notch,which was parallelized to long axial of ulna,two holes were drilled from dorsal to palmarulnaris side through the extensor carpi ulnaris sulcus of the ulna.The palmaris longus tendon was harvested and the strip of the tendon was penetrated through the radial hole.After the tips being crossed,put them through the holes of ulna,reduct the distal radioulnar joint by supinating the forearm,the strip of the tendon was sutured after being tightened,the reversed back the free end of the tendon to reconstruct the sheath of extensor carpi ulnaris tendon.Postoperatively,the upper extremity were kept in a long arm plaster in the position of elbow flexion 90° and forearm supination for 3 weeks,then the below elbow cast was replaced for another 3 weeks.Results Patients were followed-up for 1 year and 8 months 4 years and 2 months with the average of 2 years and 9 months.The rotation of wrist was improved and the handgrip strength was increased significantly.A functional evaluation was performed using the modified Mayo wrist scoring system.All patients had better wrists scores postoperatively (mean,93) compared to preoperatively (mean,68).All patients satisfied with the final result.Conclusion Dorsal ligament reconstruction should be a promise surgical modality for the old dorsal dislocation of distal radioulnar joint.

OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.

METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.

RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.

CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.

OBJECTIVETo investigate the influence of antisense phosphorothioate oligonucleotides on peroxisome proliferator-activated receptors (PPARbeta) in the TNF-alpha mediated apoptosis of HaCat cells.

METHODSHaCat cells were resuscitated and randomly divided into normal control (without transfection), sham (merely with liposome transfection), scrODN (with transfection of 4 micromol/L PPARbeta scrODN), asODN (with transfection of 4 micromol/L PPARbeta asODN), TNF-alpha with transfection of 10 micromol/L TNF-alpha), scrODN + TNF-alpha with 10 micromol/L TNF-alpha stimulation after transfection of 4 micromol/L PPARbeta scrODN), asODN + TNF-alpha with 10 micromol/L TNF-alpha stimulation after transfection of 4 micromol/L PPARbeta asODN) groups. The mRNA and protein levels of PPARbeta were determined with RT-PCR and Western blotting, respectively. The changes in cell morphology were observed with Hoechst 33258 fluorescent staining to quantitate apoptotic rate of nuclei. The effect of PPARbeta asODN on HaCat cell viability was assayed with MTT method. Activation of caspase-3 was evaluated with caspase colorimetric analysis kit.

RESULTSThe mRNA and protein expression of PPARbeta in normal control, sham, scrODN groups were similar, but it decreased obviously in asODN group. The nuclear apoptotic rate in normal control, scrODN and asODN groups were rather low, and the caspase-3 activity in these groups was also low. After 24 hours of culture, the nuclear apoptotic rate in TNF-alpha and scrODN + TNF-alpha groups were (33.1 +/- 2.7)% and (32.9 +/- 3.0)%, respectively, while that in asODN + TNF-alpha group was obviously increased (58.8 +/- 4.6)%, with the caspase-3 activity significantly higher, but the number of live cells markedly lower than that in the former 2 groups (P < 0.05).

CONCLUSIONPPARbeta expression can promote the apoptosis of HaCat cells mediated by TNF-alpha.

The influence on 10 kinds of ginsensides of different processed methods of Panacis Quinquefolii Radix was discussed. White Panacis Quinquefolii Radix (sliced and dried at -80 °C), red Panacis Quinquefolii Radix( steamed, sliced and dried at -80 °C) and commercial Radix Panacis Quinquefolii (dried by electric blast air) processed by different methods. HPLC-PDA-ESI- MS method was established before by our team. Ten kinds of ginsenosides of them were determined. The content of total ginsenosides were as follow: commercial Panacis Quinquefolii Radix > white Panacis Quinquefolii Radix > red Panacis Quinquefolii Radix. Compared with white Panacis Quinquefolii Radix, the content of Re, Rc, Rb3 and Rb2 of Red Radix Panacis Quinquefolii decreased but increased that of Rg,, Rb1. Both Rg2 and Rg, were not found in white Panacis Quinquefolii Radix and commercial Panacis Quinquefolii Radix by PDA detector, and low response in ESI-MS, while red Panacis Quinquefolii Radix was to the high content that of 0. 027% and 0.040 1%. The constituent of RA0 of red Panacis Quinquefolii Radix was higher than the other two. After Panacis Quinquefolii Radix processed, the kind and content of ginsensides were significantly changed. The constituent of some kinds of ginsensides was increased and some decreased. Rf was not found in all Panacis Quinquefolii Radix samples which were consistent with the former documents.

OBJECTIVETo explore the role of EGF in regulating HaCaT apoptosis through peroxisome proliferator-activated receptor beta (PPARbeta).

METHODSCultured HaCaT cells were divided into different groups with different additives in culture medium as control (normal culture), TNF-alpha (with addition of 10 ng/mL TNF-alpha), EGF (with addition of 20 ng/mL EGF), EGF + TNF-alpha (cells were treated with 10 ng/mL TNF-alpha for 60 mins after the exposure to 20 ng/mL EGF for 4 hs) groups. Conjugation activity and transcription activity of PPARbeta of HaCaT cells in each group were detected by electrophoretic mobility shift assay (EMSA) and luciferase gene analysis (LGA). Protein expression of PPARbeta of HaCaT cells after transfected by missense oligonucleotide (scrODN) and antisense oligonucleotide (asODN) was determined by Western blot. Caspase-3 activity and apoptosis rate were detected by flow cytometry.

RESULTSConjugation and transcription activity of PPARbeta DNA were enhanced as shown in EMSA and LGA. Compared with that of cells in groups transfected by scrODN, protein expression of PPARbeta in cells of groups transfected by asODN was obviously inhibited as shown in Western blot. Caspase-3 activity of cells in TNF-alpha and EGF + TNF-alpha groups transfected by asODN was stronger than that of cells in TNF-alpha and EGF + TNF-alpha groups transfected by scrODN (P < 0.01). Apoptosis rate of cells in control, EGF, TNF-alpha, and EGF + TNF-alpha groups which were transfected by scrODN was (7.31 +/- 0.45)%, (7.43 +/- 0.21)%, (39.78 +/- 0.65)%, (28.34 +/- 0.54)% respectively, and that in those groups transfected by asODN was (8.22 +/- 0.51)%, (7.83 +/- 0.67)%, (46.78 +/- 0.48)%, (44.69 +/- 0.83)%. Apoptosis rate of cells in TNF-alpha and EGF + TNF-alpha groups transfected by asODN was respectively higher than that in TNF-alpha and EGF + TNF-alpha groups transfected by scrODN (P < 0.01).

CONCLUSIONSEGF inhibits HaCaT KC apoptosis caused by TNF-alpha in a PPARbeta-dependent manner.
