To investigate the cell-killing effect and its possible mechanism of rClone30-hDR5 in combination with TRAIL on human hepatic carcinoma (HCC) cell line, first of all, recombinant plasmid pee12.4-hDR5 was introduced into HepG2 cells by liposome transfection. After five rounds of screening by flow cytometry, HepG2 cells expressing high levels of DR5 on cell surface were isolated. The cytotoxicity of TRAIL to selected cells was higher than that of TRAIL to HepG2 cells by MTT method (P < 0.01). The result suggested that the cloned hDR5 gene had biological activity. MTT assay showed that, rClone30- hDR5 in combination with TRAIL more efficiently inhibited the tumor growth of HepG2 cells compared to rClone30-hDR5 or TRAIL in vitro. The results of Annexin V-FITC/PI staining and Quantitative Real-time PCR indicated that rClone30-hDR5 in combination with TRAIL significantly increased the mRNA levels of caspase 3 and caspase 8, and induced the apoptosis of tumor cells. HepG2 cells were infected with rClone30-hDR5 or rClone30 at MOI of 1. The expression of hDR5 on tumor surface increased significantly by rClone30-hDR5 compared to that by rClone30, which contributed to the sensitivity to TRAIL. In conclusion, rClone30-hDR5 in combination with TRAIL has potential application value in cancer treatment.

This study was purposed to investigate the effect of bortezomib (Bor) and arsenic trioxide (As(2)O(3)) combination on multiple myeloma cell line KM3 and its mechanisms. KM3 cells were cultured with different concentration of Bor or As(2)O(3) as well as both for a certain time. The cell proliferation was analysed by MTT assay and the concentration of 50% proliferation inhibition (IC(50)) was calculated. Early apoptosis and late apoptosis of KM3 cells were detected by Annexin-V-FITC Kit, and the change of transmembrane potential was measured by flow cytometry. mRNA of Caspase-3, Bim and Bcl-xL were detected by RT-PCR. The results showed that the proliferation inhibitory rate of KM3 cells treated by Bor plus As(2)O(3) was much higher than that of KM3 cells treated by Bor only for 72 h [ (27.64 ± 0.81)% vs (21.67 ± 2.20)%, P < 0.05]. There were more KM3 cells treated by Bor plus As(2)O(3) in early apoptosis at 48 h and late apoptosis at 72 h than that of KM3 cells treated only by Bor [ (53.20 ± 3.70)% vs (35.40 ± 2.58)%, P < 0.01; (63.96 ± 2.97)% vs (54.08 ± 3.76)%, P < 0.01]. Transmembrane potential (Δψm) of KM3 cells treated by Bor plus As(2)O(3) decreased more at 48 h, as compared with Bor alone. The expression levels of caspase-3 mRNA and Bim mRNA in KM3 cells treated with Bor plus As(2)O(3) were higher than that in KM3 cells treated with Bor alone. But the expression level of Bcl-xL mRNA was lower than that in KM3 cells treated with Bor alone. It is concluded that As(2)O(3) can enhance the apoptosis-inducing effect of Bor on multiple myeloma cell line KM3, which is associated with decreasing the expression of Bcl-xl mRNA and increasing the expression of Caspase-3 and Bim mRNA.

OBJECTIVETo investigate cause of chronic wounds and related status of patients so as to provide strategy for study and treatment of chronic wounds and establishment of health policy.

METHODSA total of twelve thousand one hundred and sixty-one cases hospitalized in our hospital in 2008 were enrolled in the study. A chronic wound was defined as skin tissue defect which could not heal after one month of treatment. Medical records were thus screened. Then a retrospective study was performed on patients with chronic wounds with analysis of age, gender, injury cause, therapy, and average length of hospital stay. Data were processed with chi-square test and one-way analysis of variance.

RESULTSInvestigation showed: 397 out of 12 161 cases (accounting for 3.3%) were recognized as having chronic wounds. (1) The main causes for chronic wound were burn, diabetes, and pressure ulcer, accounting for 59.9% (238/397), 15.6% (62/397), 10.8% (43/397), respectively. The other causes were operative injury, infection, varicosity, etc. There was statistical difference among the numbers of patients with chronic wounds with regard to various causes of injury (χ(2) = 136.21, P = 0.001). (2) Among patients with chronic wound, the ratio of male and female was 2.0:1.0 with mean age of (44 ± 23) years, and the highest ratio occurred in patients older than 70 years. There was significant difference in the numbers of patients with chronic wound among different age groups (χ(2) = 24.12, P = 0.025). There was statistical difference among the numbers of patients with chronic wound in different age groups with each cause of injury (with χ(2) values from 7.86 to 28.31, P values all below 0.05). (3) All patients with chronic wounds received traditional dressing. In 60.5% (240/397) and 86.4% (343/397) of patients, operative treatment or antibiotics were given. (4) The average length of hospital stay in patients with chronic wound [(38 ± 27) d] was longer as compared with that of all the inpatients in the same period [(15 ± 7) d, F = 22.82, P = 0.012]. There was obvious difference in the average length of hospital stay among patients with chronic wound caused by different reasons (F = 24.06, P = 0.036), in which burn injury resulted in the longest length of hospital stay [(47 ± 27) d].

CONCLUSIONSChronic wounds are mainly caused by diabetes and burn, and characterized by old age and longer length of hospital stay. It is necessary to strengthen translational research and related policy making, so that more rational treatment can be applied for patients with chronic wounds.

Meloxicam concentration in skin was determined following topical administration of meloxicam patches in hairless mouse. Samples were analysized by HPLC coupled with microdialysis sampling technique, in which in vivo recovery of probe was characterized by the retrodialysis method. It was indicated that the in vivo recovery of the probe was 14.0%. The range of steady state concentration of meloxicam in dialysate was 24-50 ng x mL(-1), and that was 170-360 ng x mL(-1) in the hairless mouse skin. Steady state concentration of meloxicam was reached shortly after the application of meloxicam patches, which was maintained during the period of experiment.
