Objective To investigate the effect of cold atmospheric plasma (CAP) on the healing of skin ulcers using Balb/c mice. Methods Wounds with a diameter 6 mm were created on each side of the backs of BalB/c mice ( n = 150) using a punch bioptome. The mice were assigned randomly into a control group ( wounds healed naturally), a laser group (wounds treated with a He-Ne laser for 10 min daily) and a CAP group (wounds treated with CAP for 10 min daily). Wound healing was evaluated on postoperative days (PODs) 4, 7, 10 and 14 in terms of percent wound closure. Ten mice per group were sacrificed on each of the evaluation days. Both wounds were removed and a histological examination was conducted. A scoring system was used to evaluate the wounds. The expression of vascular endothelial growth factors (VEGFs) in the wounded tissue was detected by using immunohistochemical methods on POD 7. The results were quantified using an HPIAS-1000 system. Results Compared with the control group, the average percentage of wound healing was significantly greater in the CAP group on PODs 7 and 10. The average scores on the histological examination were significantly higher in the CAP group on PODs 7, 10 and 14. Compared with the other two groups, the expression of VEGF was up-regulated significantly in the CAP group.Conclusions CAP can positively affect the wound healing process. This might be related to the up-regulation of VEGF in the wounded tissues.

Objective To prepare the curcumin self-microemulsion, observe the morphology and size diameter distribution of the microemulsion, and compare the absorption kinetics of curcumin microemulsion and micelle. To investigate the best absorption segment of curcumin microemulsion in intestnum tenue and the absorption of curcumin self-microemulsion in mouse gastrointestinal tract. MethodsThe intestine in rats was cannulated in situ recirculation. The absorption of curcumin microemulsion was calculated by its decrement in intestnum tenue.The inabsorbable curcumin in all content together with feces in mouse gastrointestinal tract was obtained and used to calculate the absorption rate of curcumin. ResultsThe curcumin microemulsion presented as small spherical drops or something similar under transmission electron microscope (TEM) with the average diameter of about 21.6 nm. The absorption constants of curcumin microemulsion and micelle was 0.042 5 and 0.019 5 /h , the main segments of curcumin microemulsion absorption were intestinum duodenum and intestinum jejunum. The absorption rate of curcumin self-microemulsion was 2.5 times as much as curcumin. ConclusionThe curcumin self-microemulsion could improve the absorption of curcumin in vivo in animal evidently.

OBJECTIVETo explore the relationship between the myelodysplastic syndromes (MDS) and autoimmune disorders (AID).

METHODSThe clinical data of 117 MDS patients were reviewed.

RESULTSNineteen (16.2%) of 117 MDS patients had AIDs. The commonest AID associated with MDS was rheumatoid arthritis (31.6%) and ulcerative colitis (26.3%). Compared with that in MDS patients without autoimmune disorders, the leukemic transformation rate was not increased in the MDS/AID but the median survival time was shorter in MDS/AID patients.

CONCLUSIONMDS patients associated with autoimmune disorders may be an unfavorable factor for their prognosis.

Objective To study the relationship of symptoms of female gonococcal infections to Chlamydia trachomatis infection, serum sex hormone levels, etc. Methods A total of 136 gonorrhea female patients without obvious symptoms were recruited in this study together with 45 gonorrhea patients with obvious symptoms as the controls. Serum progesterone (P) and estradiol (E2) levels were measured by radio immunoassay (RIA). Cervical swabs were obtained from the subjects and eluted into isotonic saline solution, the elution was divided into 2 portions and tested for the levels of TNF-α and IL-1β by ELISA and for the DNA of C. Trachomatis and N. Gonorrhea with PCR. Statistical analysis was carried out by SPSS for Windows (version 12.0). Results There was no statistical correlation between C. Trachomatis infection and asymptomatic status of female gonococcal infection (χ2 = 0.016, P > 0.05). However, the decrease in the level of TNF-α and IL-1β significantly correlated with the increase in serum progestogen (r = -0.8798, -0.8935, respectively, both P < 0.01). Conclusion The high serum level of progesterone may be associated with the asymptomatic status of gonococcal infection.

Objective To evaluate the effects of progesterone on polymorphonuclear leukocyte (PMN)-mediated inflammatory responses to gonococcal infection. Methods Peripheral neutrophils were isolated from heparinized peripheral blood obtained from normal individuals, then divided into 4 groups: progesterone group (pretreated with progesterone only), gonococcus group (stimulated with gonococcal suspension), intervention group (pretreated with progesterone followed by stimuation with gonococcal suspension), and control group (receiving no pretreatment or stimulation). Real-time RT-PCR was conducted to detect the mRNA expression levels of inducible nitric oxide synthase (iNOS), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β)in neutrophils from all groups at 0, 3, 8, 12 and 24 hours after the last treatment, and iNOS protein levels were measured by Western-blot in gonococcus group and intervention group. Results Real-time RT-PCR indicated that the expression levels of iNOS, TNF-α and IL-1β mRNA increased in gonococcus group and intervention group, and reached their peak at 8 hours in gonococcus group, while no significant changes were noted in the above parameters in progesterone group or control group. Also, the level of iNOS, TNF-α and IL-1β mRNA was lower in intervention group than that in the gonococcus group (P ＜ 0.05). Western blot showed an elevation in iNOS protein expression in both gonococcus group and intervention group, and the former group was higher than the latter group in the parameter (P ＜ 0.05). Conclusions Progesterone can downregulate the expressions of iNOS, TNF-α and IL-1 β by PMNs, inhibit the PMN-induced inflammatory responses induced by gonococcal infection, which is likely to be associated with the asymptomatic gonococcal infection in women.

Objective To investigate the effect of recombinant murine interleukin-23(rIL-23)on systemic candidiasis in a murine model.Methods A cyclophosphamide-induced immunosuppressed murine model of systemic candidiasis was established.The mice were divided into control group and rIL-23 treatment group.Colony forming units(CFU)of the kidney and spleen were determined by using plating dilution method.The histopathological changes and degree of infection of the kidney and spleen were graded.Meanwhile,the levels of interferon gamma(IFN-γ)in the spleen were measured by enzyme-linked immunosorbent assay.Results On the 2nd,3rd and 7th day after Candida albicans infection the number of CFU of the fungi in the kidney in the control group was significantly greater than that in rIL-23 treatment group(P＜0.01).The number of CFU of the fungi on the 2nd,3rd and 7th day after Candida albicans infection in the spleen in control group was also greater than that in rIL-23 treatment group,but without statistically significant difference(P＞0.05).The scores of histopathological changes in the kidney in rIL-23 treatment group were lower than those in control group(P＜0.01),and the degree of infection was milder in rIL-23 treatment group.The scores of histopathological changes in the spleen in rIL-23 treatment group were also lower than those in control group,but without statistically significant difference(P＞0.05).The levels of IFN-γ in the spleen on the 2nd,3rd and 7th day after infection in rIL-23 treatment group were significantly higher than those in control group(P＜0.01).Conclusion rIL-23 has protective effect on murine systemic candidiasis.
