OBJECTIVETo investigate the role of p38 MAPK on ischemic postconditioning (IPO) attenuating pneumocyte apoptosis after lung ischemia/reperfusion injury (LIRI).
METHODSForty adult male SD rats were randomly divided into 5 groups based upon the intervention (n = 8): control group (C), LIR group (I/R), LIR + IPO group (IPO), IPO + solution control group (D), IPO + SB203580 group (SB). Left lung tissue was isolated after the 2 hours of reperfusion, the ratio of wet lung weight to dry lung weight (W/D), and total lung water content (TLW) were measured. The histological structure of the left lung was observed under light and electron transmission microscopes, and scored by alveolar damage index of quantitative assessment (IQA). Apoptosis index (AI) of lung tissue was determined by terminal deoxynuleotidyl transferase mediated dUTP nick end and labeling (TUNEL) method. The mRNA expression and protein levels of and Bax were measured by RT-PCR and quantitative immunohistochemistry (IHC).
RESULTSCompared with C group, W/D, TLW, IQA, AI and the expression of Bax of I/R were significantly increased, the expression of Bcl-2 and Bcl-2/Bax were significantly decreased (P < 0.05, P < 0.01), and was obviously morphological abnormality in lung tissue. Compared with I/R group, all the indexes of IPO except for the expression of Bcl-2 and Bcl-2/ Bax were obviously reduced, the expression of Bcl-2 and Bcl-2/Bax were increased (P < 0.05, P < 0.01). All the indexes between D and IPO were little or not significant( P > 0.05). The expression of Bcl-2 and Bcl-2/Bax of SB were significantly increased and other indexes were reduced than those of IPO (P < 0.05, P < 0.01).
CONCLUSIONIPO may attenuate pneumocyte apoptosis in LIRI by inactivation of p38 MAPK, up-regulating expression of Bcl-2/Bax ratio.

Objective To investigate the role of T helper 17 cells/interleukin?17(Th17/IL?17) axis in the occurrence of vaginal candidiasis in mice. Methods A total of 120 female BALB/c mice were randomly and equally divided into Ei, En, Ci and Cn groups. Three days before vaginal inoculation, estrogen (Ei and En)groups and control(Ci and Cn)groups received subcutaneous injection of 0.05 mg estradiol and 0.1 ml sterilized soybean oil at the hind legs, respectively, and then the hormone treatment continued every other day until the end of experiment. Infected(Ei and Ci)groups and noninfected(En and Cn) groups were inoculated intravaginally with 10μl(5 × 104 conidia)of Candida albicans suspension and 10μl of sterilized phosphate?buffered saline, respectively. Ten mice were randomly selected from each group and sacrificed on day 3, 7 and 14 after inoculation. The intact vagina tissues were resected and then frozen in liquid nitrogen or embedded in paraffin. Real?time fluorescence?based quantitative PCR(qRT?PCR)and immunofluorescent staining were performed to measure mRNA expression and immunofluorescence intensities of retinoic acid?related orphan receptorγt(RORγt), RORα and IL?17, respectively. Western blot analysis was conducted to determine protein expression of RORγt and IL?17. Results Laser scanning confocal microscopy showed that RORγt, RORα and IL?17 immunofluorescence was mainly located at inflammatory cells of the lamina propria and blood vessels in En and Cn groups, at mucosal epithelium, adherent hyphae, and inflammatory cells of the lamina propria and blood vessels in Ci group, and at mucosal epithelium, vaginal canal and endocytosed hyphae, and inflammatory cells of the lamina propria and blood vessels in Ei group. qRT?PCR and immunofluorescent staining uncovered that mRNA expression and immunofluorescence intensities of RORγt, RORα and IL?17 were significantly higher in En, Ci and Ei groups than in Cn group at the same time points(all P<0.05), as well as in the Ei group than in En and Ci groups(both P<0.05), and were increased gradually over time in En, Ci and Ei groups, but not in the Cn group. Additionally, mRNA expression and immunofluorescence intensities of RORγt and RORαand IL?17 generally peaked on day 14 after inoculation, while the immunofluorescence intensity of IL?17 peaked on day 7 (P < 0.05). Western blot analysis revealed that protein expression of RORγt and IL?17 was significantly higher in the infected(Ei and Ci)groups than in the noninfected(En and Cn)groups at the same time points(RORγt:F=45.685, P<0.001;IL?17:F=29.655, P<0.01), and was highest in the Ei group(P<0.05);however, no significant differences were observed between Cn and En groups(both P>0.05). Moreover, RORγt and IL?17 protein expression in Ci and Ei groups was obviously up?regulated on day 7 after inoculation (RORγt: F = 13.137, P < 0.001; IL?17: F = 11.182, P < 0.001), but was not increased further on day 14. Conclusion Vaginal candida infection can up?regulate the expression of RORγt, RORα and IL?17, suggesting that Th17/IL?17 axis may be involved in the occurrence of vaginal candidiasis in BALB/c mice.
