The biochemical mechanism of degrading keratins by S.fradiae var S-221 was primarily studied.The compounds (Na_ 2 SO_ 4 , Na_ 2 SO_ 3 and sulfdryl acohol), which respecitively enhance specific activity of keratinase, activate keratinase intensively and mainly act on the disulfide bonds reductase in the keratinase, Na_ 2 SO_ 3 activates intensively both disulfide bonds reductase and polypeptide hydrolytase at 0.01 mol/L, whereas Na_ 2 S_ 2 O_ 3 , which acts on the disulfide bonds reductase, inhibits keratinase.On the condition that substrate, keratins exists, S.fradiae var S-221 is induced to produce exo-keratinase, which is a multiproteinase, containing disulfide bonds reductase, which is a key enzyme degrading keratins, then, with polypeptidic, hydrolytase, graduately hydrolyzates denatured keratins into polypeptides, oligopeptides and free amino acids, so that keratins have been decomposed completely.Sulfur in the keratins was transferred into sulfhydryl compounds, H_ 2 S and sulfates in the course of keratinolysine.

Objective To investigate the efficacy and toxicity of neoadjuvant chemotherapy of modified FOLFOX7 regimen in the treatment of advanced gastric cancer. Methods The clinical data of 30 patients with advanced gastric cancer who had been admitted to Beijing Friendship Hospital from June 2005 to January 2009 were retrospectively analyzed. All patients received modified FOLFOX7 regimen [oxaliplatin (100 mg/m~2) + fluorouracil (2400 mg/m~2) + calcium folinate (400 mg/m~2)] for 2-4 courses before operation. The efficacy and toxicity of the modified FOLFOX7 were evaluated before and after the operation. All data were analyzed via chi-square test. Results The pre-and postoperative downstaging rates were 27% (8/30) and 47% (14/30), respectively. The total effective rate of modified FOLFOX7 regimen was 43% (13/30). Complete remission was observed in 1 patient. The toxicity was mild. Radical resection was accomplished in 28 patients (93%). There was no statistical difference between the 2 criteria in evaluating the efficacy of modified FOLFOX7 regimen (χ~2= 2.584, P>0.05). Conclusion Modified FOLFOX7 regimen is effective and well-tolerable for patients with advanced gastric cancer.

Background The data on the prognostic values of high sensitivity C-reactive protein (hsCRP) levels in patients with advanced symp-tomatic heart failure (HF) receiving cardiac resynchronization therapy (CRT) are scarce. The aim of present study was to investigate the association of serum hsCRP levels with left ventricle reverse remodeling after six months of CRT as well as long-term outcome. Methods A total of 232 CRT patients were included. The assessment of hsCRP values, clinical status and echocardiographic data were performed at baseline and after six months of CRT. Long-term follow-up included all-cause mortality and hospitalizations for HF. Results During the mean follow-up periods of 31.3 ± 31.5 months, elevated hsCRP (>3 mg/L) prior to CRT was associated with a significant 2.39-fold increase (P=0.006) in the risk of death or HF hospitalizations. At 6-month follow-up, patients who responded to CRT showed significant reductions or maintained low in hsCRP levels (–0.5 ± 4.1 mg/L reduction) compared with non-responders (1.7 ± 6.1 mg/L increase, P=0.018). Com-pared with patients in whom 6-month hsCRP levels were reduced or remained low, patients in whom 6-month hsCRP levels were increased or maintained high experienced a significantly higher risk of subsequent death or HF hospitalizations (Log-rank P<0.001). The echocardio-graphic improvement was also better among patients in whom 6-month hsCRP levels were reduced or remained low compared to those in whom 6-month hsCRP levels were raised or maintained high. Conclusions Our findings demonstrated that measurement of baseline and follow-up hsCRP levels may be useful as prognostic markers for timely potential risk stratification and subsequent appropriate treatment strategies in patients with advanced HF undergoing CRT.

Objective: To explore the effects of cardiac resynchronization therapy (CRT) in patients with dispersion of re-polarization and ventricular arrhythmia.
Methods: A total of 86 consecutive patents with CRT implantation were enrolled. According to weather absolute value of LVEF increased≥10% from baseline at 6 months after CRT implantation, the patients were divided into 2 groups: Response group and Non-response group,n=43 in each group. Dispersion of re-polarization indexes as QRS duration, QTc interval, TpTe interval and the events of ventricular arrhythmia were compared between 2 groups at different time points after CRT.
Results:①In Response group, compared with pre-operation, QRS duration and TpTe interval were shorter at 1 year and within 24h after CRT implantation, allP<0.05, while the above indexes were similar in Non-response group, allP>0.05.②During 1 year after CRT implantation, the incidences of PVCs and PVC runs in Response group were much less than those in Non-response group, for lgPVCs: (1.78 ± 0.77) vs (2.73 ± 0.61), for lgPVC runs: (0.64 ± 0.48) vs (1.98 ± 0.72),P<0.05.③Multi liner regression analysis demonstrated that TpTe interval within 24h after CRT implantation was an independent predictor for both lgPVCs: (B=0.143, OR=1.154,P=0.001) and lgPVC runs: (B=0.122, OR=1.047,P=0.001).
Conclusion: CRT ventricular reverse remodeling may reduce dispersion of re-polarization and the risk of ventricular arrhythmia, therefore improve the prognosis in relevant patients; TpTe interval within 24h after CRT had the predictive value for ventricular arrhythmia.

Objective To investigate the effect of intermittent high glucose on proliferation, apoptosis, and cell cycle progression of INS-1 cells, and the possible intracellular pathways activated by intermittent high glucose. Methods Cell viability was evaluated by cell counting kit, the cell cycle was determined by flow cytometry,Annexin-V/PI double-labeled cell apoptosis detection kit was used to monitor cell apoptosis. Cell cycle related protein Skp2 and p27 expressions were detected by Western blot. Results ( 1 ) Both intermittent and constant high glucose significantly inhibited the growth of INS-1 cells, and the former effect was more significant. ( 2 ) Intermittent and constant high glucose levels significantly increased apoptosis in INS-1 cells, and the former effect was more significant. (3) Intermittent and constant high glucose levels significantly inhibited the cell process, the G0/G1 cell cycle arrest also was induced by intermittent high glucose, resulting in lowered proportion of the G2/M phase and S phase of INS-1 cells. (4) Intermittent and constant high glucose significantly decreased the level of protein Skp2 and increased the level of cell cycle related protein p27. Conclusion Intermittent high glucose levels affect INS-1 cell growth and proliferation, as well as induce cell apoptosis, probably by decreasing the level of protein Skp2 and increasing the level of p27 in the cells, resulting in arrest of progression through the G1 phase to the S phase of INS1 cells, and thus impairment of cell proliferation.
