Objective:To investigate the expression and clinical significance of effector T cell (Teff), regulatory T cell (Treg) and their cytokines in patients with vitiligo.Methods:84 patients with vitiligo (38 cases in stable stage, 46 cases in advanced stage) who were admitted to the Dermatology Department of the Dezhou People's Hospital between June 2018 and June 2019 and 30 healthy people (control group) were enrolled in the study. The levels of Teff subsets and Treg cells in peripheral blood were detected by flow cytometry. The levels of Teff subsets and Treg cells-associated cytokines were detected by enzyme-linked immunosorbent assay (ELISA). The relationship between Teff subsets and Treg cells levels in peripheral blood, relationship between Teff subgroups, Treg cells-associated cytokines and course of vitiligo, skin lesion area were analyzed.Results:The levels of T helper cell (Th)17 and Th22 in peripheral blood of vitiligo group were significantly higher than those of control group, while levels of Treg cells were significantly lower than control group ( P<0.05). Compared with the stable vitiligo group, the levels of Th17 and Th22 in peripheral blood were higher and levels of Treg cells were lower in the advanced vitiligo group ( P<0.05). Treg cell level was negatively correlated with Th17 cell level ( r=-0.303, P=0.001), and negatively correlated with Th22 cell level ( r=-0.200, P=0.033). The levels of serum interleukin (IL)-17 and IL-22 in vitiligo group were significantly higher than those in control group, while the level of transforming growth factor-β (TGF-β) was significantly lower than that in control group ( P<0.05). Compared with the stable vitiligo group, levels of serum IL-17 and IL-22 were higher and level of TGF-β was lower in the advanced vitiligo group ( P<0.05). Correlation analysis showed that levels of IL-17 and IL-22 were positively correlated with skin lesion area ( r=0.361, 0.288, P<0.05), and level of TGF-β was negatively correlated with skin lesion area ( r=-0.312, P<0.05). Conclusions:Teff/Treg cells are unbalanced in patients with vitiligo, showing obvious shift to Teff subsets. The progression of vitiligo may be related to Teff subsets and Treg cells-associated cytokines.

Objective To observe changes of the pancreas after limb ischemia reperfusion, and the protective effect of taurine (Tau) postconditioning. Methods Twenty-four male SD rats were randomly divided into control group (Control), limb ischemia reperfusion (LIR) group, and taurine postconditioning (Tau) group (n=8 for each group). Plasma contents of xanthine oxidase (XOD), malondialdehyde (MDA), reactive oxygen species (ROS), superoxide dismutase (SOD), pancreatic amylase (AMS), pancreatic lipase (LPS) and trypsin were detected in three groups. Morphological changes of the pancreas were observed using optical microscopy. The expressions of anti-C/enhancer-binding protein homologous protein (CHOP) in pancreas were analyzed by immunohistochemistry assay. TUNEL staining was performed to estimate the apoptosis of pancre-atic cells. Results Compared with the control group and Tau group, plasma contents of MDA, XOD, ROS, AMS, LPS, and trypsin were significantly increased in LIR group, but the level of SOD was significantly lower in LIR group ( P<0.05). HE staining showed that acinar structure was disrupted , pancreatic lobule gap widened, stromal vascular dilatation and conges-tion were observed in LIR group. The perivascular infiltration of inflammatory cells appeared, islet cells were damaged with irregular islet. The immunohistochemical analysis showed the increased expression of CHOP in pancreas in LIR group than that of Tau group. And the pancreatic apoptosis was enhanced in LIR group detected by TUNEL staining. Conclusion Tau-rine postconditioning can ameliorate pancreatic injury following limb ischemia reperfusion, which may be related to the inhi-bition of oxidative stress, down-regulation of CHOP expression, thereby reducing endoplasmic reticulum stress-induced apoptosis.

Objective To approach the effects of full Marathon on striated muscle and renal function of Marathon amateurs without complaints. Methods A prospective self-paired design study was conducted. The amateurs without body discomfort, hematuria, brown urine, or persistent muscle pain within 1 week after the 2012 Xiamen International Marathon Race were enrolled voluntarily. The peripheral blood and random urine specimens of all subjects under static status 1 week before the race and after the race instantly (within 10 minutes after finishing the race) were collected to detect markers of renal function and striated muscle injury. Results Sixty-one subjects were included in the final analysis of the study with full Marathon of 42.195 km and mean race time of (297.05± 55.60) minutes. Compared with those under static status before the race, the markers of renal function including the levels of urinary N-acetyl-beta-D-glucusamidase [NAG (U/L): 64.00 (54.50, 85.50) vs. 9.50 (8.10, 11.50)], urinary β2-microspheres protein [β2-MG (μg/L): 261.00 (128.50, 1 608.00) vs. 66.60 (33.75, 123.00)], random urinary creatinine [UCr (μmol/L): 19 066.56±10 938.31 vs. 5 872.52±4 363.20] and serum creatinine [SCr (μmol/L): 129.97±25.84 vs. 97.39±14.51] immediately after the race were significantly increased (all P < 0.01); the markers of muscle injury including the levels of serum creatine kinase [CK (U/L): 864.00 (504.00, 1 644.00) vs. 164.00 (128.00, 256.00)], lactic dehydrogenase [LDH (U/L): 383.26±141.69 vs. 182.23±41.12], myoglobin [Mb (mg/L): 1 880.00 (1 080.00, 3 300.00) vs. 42.00 (36.00, 54.50)], alanine aminotransferase [ALT (U/L): 27.0 (19.5, 38.0) vs. 24.0 (15.0, 29.5)] and aspartate transaminase [AST (U/L): 52.07±25.13 vs. 28.28±11.86] were also significantly increased (all P < 0.01), and the increase in CK, Mb, and LDH were more significant. It was shown by correlation analysis that CK after race was negatively correlated with age (r = -0.352, P = 0.005) and body mass index (r = -0.271, P = 0.035), and it was positively correlated with racing time (r = 0.387, P = 0.002) and urinary β2-MG after the race instantly (r = 0.364, P = 0.004). Mb after race was negatively correlated with body mass index (r = -0.331, P = 0.009), and it was positively correlated with urinary β2-MG after the race instantly (r = 0.315, P = 0.013). LDH after race was negatively correlated with age (r = -0.275, P = 0.032) and body mass index (r = -0.377, P = 0.003), and it was positively correlated with urinary β2-MG after the race instantly (r = 0.424, P = 0.001). Conclusion Full Marathon could significantly impact striated muscle and renal function of Marathon amateurs without complaints.

Objective To investigate the effects and mechanism of glucagon-like peptide-1 ( GLP-1 ) receptor agonist liraglutide on the proliferation and apoptosis of human pancreatic cancer cells. Methods The human pancreatic cancer cell line MIA PaCa-2 was incubated for 24 h with liraglutide at various concentrations (10-1 000 nmol/ L), or with 100 nmol/ L liraglutide for various durations (0-72 h). Cell proliferation was determined by Cell Counting Kit-8 (CCK-8) analysis. RT-PCR and Western blot were used to detect the mRNA and protein expression levels of related genes. Results GLP-1 receptor was expressed in the MIA PaCa-2 cells. Liraglutide suppressed cell proliferation, up-regulated the expression levels of pro-apoptotic protein Bax and down-regulated the expression levels of anti-apoptotic protein Bcl2 in human pancreatic cancer cells in a dose- and time-dependent manner. Meanwhile, liraglutide down-regulated the expression levels of insulin receptor (INSR) and insulin-like growth factor-1 receptor (IGF-1R), and the phosphorylation levels of their downstream signaling proteins Erk1 / 2 and Akt, in a dose- and time-dependent way. Conclusion Liraglutide inhibits proliferation and promotes apoptosis of human pancreatic cancer cells; the process may be mediated via suppressing the expression of INSR and IGF-1R and inhibiting activation of the downstream MEK/ Erk1 / 2 and PI3k/ Akt pathways.

BACKGROUND:In the process of designing knee joint prosthesis and operating total knee arthroplasty for the Chinese people, we should not only take into account the proximal tibial anatomical characteristics and the difference of geometry, but also should pay attention to the differences between different races. OBJECTIVE:To compare the anatomical morphological differences between Mongolian and Han nationality through measuring the CT tomography scanning and three-dimensional reconstruction measurement of tibia proximal part of Han and Mongolian nationality, so as to provide the data references for prosthesis selection used for total knee arthroplasty. METHODS:Total y 60 patients who received the treatment at the Department of Joint Surgery were col ected, and divided into Han nationality and Mongolian nationality groups (n=30/group, 15 males and 15 females in each group). The age was (36.00+7.22) years old. 16-row helical CT scan (American GE Lightspeed 16) was used for spiral scanning, slice thickness 0.625 mm. Scanning images were exported in DICOM format and saved. Digital three-dimensional reconstruction measurement was conducted using Mimics 15.0 three-dimensional reconstruction software. The tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter were measured respectively to observe whether there were any differences among sex, sides and nationality. RESULTS AND CONCLUSION:There were no significant differences in the above indicators between left and right sides (P>0.05). There were significant differences in tibial plateau width, anteroposterior diameter of the medial tibial plateau and lateral anteroposterior diameter between males and females, and Han and Mongolian nationality groups (P<0.05). Specific performed in:(1) There was significant difference in the morphological measurement parameters of proximal tibia between sex for Han and Mongolian nationality, and the mean value of male was larger compared with that of female. (2) There was certain significant difference in the part of the parameter indicators between Han and Mongolian nationality groups. These results suggest that the prosthesis should be chose and placed correctly according to the differences of morphological characteristics, gender, nationality, region of the Chinese people. (3) Digital three-dimensional reconstruction technology and individualized design can choose suitable prosthesis for different people, so as to ensure a good repair effect in patients after total knee replacement.
