Abstract
To evaluate the changes in myocardial enzymes and plasma epirubicin concentration following administration by micro-pump (MP) and intravenous drip (ID) in breast cancer patients.11 self-controlled breast cancer patients were recruited for a trial with epirubicin administration by MP for 48 h and by ID for 1 h during 2 cycles of treatment. Plasma concentration of epirubicin at different time points was determined using LC-MS/MS. The levels of myocardial enzymes before and after chemotherapy were compared. Another group of patients receiving epirubicin by ID (n=4) or MP (n=9) were monitored for 4 months.8 patients completed the self-controlled study. The peak concentration of epirubicin in the MP group and the ID group were 21.84±18.85 ng/mL and 294.80±225.54 ng/mL, respectively. The MP group had a longer duration (54~60 h) of plasma concentration of epirubicin not less than 10 ng/mL than that of the ID group (8~14 h). There was significant difference for the alteration of myocardial enzymes before and after chemotherapy (p<0.05) in the ID group, whereas the MP group showed no significant difference (p>0.05). The increased range of myocardial enzymes after chemotherapy in the ID group was larger than that of the MP group and the difference was significant (p<0.05). There is an increased cardiotoxicity in patients receiving epirubicin by ID during the 4-month trial.Administration of epirubicin by MP maintained an effective drug concentration for a longer period of time than by ID. The higher peak plasma concentration observed following epirubicin administration by ID may lead to cardiac toxicity.

Abstract
Objective: This study investigated the clinical significance of expression of caveolin-1 - a plasma membrane protein involved in caveola formation, endocytosis, signal transduction and angiogenesis - inthe pathogenesis of psoriasis vulgaris. Methods: A total of 20 patients with psoriasis vulgaris and 20 healthy volunteers were recruited. The expressions of caveolin-1, Ki-67 (marker of cell proliferation) and CD34 (marker of angiogenesis) in skin biopsies were detected by immunohistochemistry, and the level of caveolin-1 protein was quantified by Western blotting. Clinical severity was assessed using the Psoriasis Area and Severity Index (PASI) score. Correlations between caveolin-1 expression and psoriasis severity, cell proliferation and angiogenesis were analysed using the Spearman rank correlation test. Results: Expression of caveolin-1 was significantly lower in psoriasis samples than in healthy skin samples. In psoriasis lesions, the level of caveolin-1 expression was inversely correlated with the severity of psoriasis, cell proliferation and angiogenesis. Conclusions: The level of caveolin-1 expression seems to be related to the clinical severity of psoriasis, and may play a role in the abnormal keratinocyte hyperplasia and angiogenesis seen in this condition.

Abstract
BACKGROUND Graft-versus-host disease (GVHD) is a rare complication after liver transplantation with an extremely poor prognosis; its occurrence offers great challenges. METHODS We have reported herein one case of acute GVHD after liver transplantation who was treated with a traditional Chinese medicine named Korean Red Ginseng (KRG). RESULTS The acute GVHD was successfully cured by KRG. CONCLUSIONS The successful salvage of acute GVHD after liver transplantation by KRG may provide a new viable therapeutic option.

Abstract
The transformation of DDT was studied in an anaerobic system of dissimilatory iron-reducing bacteria (Shewanella decolorationis S12) and iron oxide (alpha-FeOOH). The results showed that S. decolorationis could reduce DDT into DDD, and DDT transformation rate was accelerated by the presence of alpha-FeOOH. DDD was observed as the primary transformation product, which was demonstrated to be transformed in the abiotic system of Fe(2+)+alpha-FeOOH and the system of DIRB+alpha-FeOOH. The intermediates of DDMS and DBP were detected after 9 months, likely suggesting that reductive dechlorination was the main dechlorination pathway of DDT in the iron-reducing system. The enhanced reductive dechlorination of DDT was mainly due to biogenic Fe(II) sorbed on the surface of alpha-FeOOH, which can serve as a mediator for the transformation of DDT. This study demonstrated the important role of DIRB and iron oxide on DDT and DDD transformation under anaerobic iron-reducing environments.

Abstract
We report experimental observations of the negative-group-velocity (v(g)) phenomenon in an integrated-optical two-port ring-resonator circuit. We demonstrate that when the v(g) is negative, the (main) peak of output pulse appears earlier than the peak of a reference pulse, while for a positive v(g), the situation is the other way around. We observed that a pulse splitting phenomenon occurs in the neighborhood of the critical-coupling point. This pulse splitting limits the maximum achievable delay and advancement of a single device as well as facilitating a smooth transition from highly advanced to highly delayed pulse, and vice versa, across the critical-coupling point.

Abstract
A novel method is presented for determining the group index, intensity enhancement and delay times for waveguide gratings, based on (Rayleigh) scattering observations. This far-field scattering microscopy (FScM) method is compared with the phase shift method and a method that uses the transmission spectrum to quantify the slow wave properties. We find a minimum group velocity of 0.04c and a maximum intensity enhancement of ~14.5 for a 1000-period grating and a maximum group delay of ~80 ps for a 2000-period grating. Furthermore, we show that the FScM method can be used for both displaying the intensity distribution of the Bloch resonances and for investigating out of plane losses. Finally, an application is discussed for the slow-wave grating as index sensor able to detect a minimum cladding index change of 10(-8), assuming a transmission detection limit of 10(-4).

Abstract
Screening and identifying molecules target to checkpoint pathways has fostered the development of checkpoint-based anticancer strategies. Among these targets, inhibition of chk2 may induce cell death for tumors whose growth depends on enhanced chk2 activity. However, improvement of the potency and specificity of such therapeutics remains a major challenge. To resolve this problem, we constructed M3, a novel recombinant adenovirus with a 27-bp deletion in E1A CR2 region by which to realize tumor-specific replication, and an 829-bp of antisense chk2 fragment inserted into the E3 coding region. In this design, M3 exploited the native adenovirus E3 promoters to express antisense chk2 cDNA in a viral replication-dependent fashion, and preferentially silenced the chk2 gene in tumor cells. In vitro and in vivo assays confirmed that downregulated chk2 expression induced by M3 infection was tumor-specific and virus replication-dependent. Furthermore, systemic administration of M3 combined with a low dose of cisplatin cured 75% (9/12) of orthotopic hepatic carcinoma mouse models that were otherwise resistant to cisplatin. Our results indicated that the upcoming development in this field would improve the antitumor efficacy and maximize the synergistic effect of oncolytic viruses administered with traditional chemotherapy or radiotherapy.
