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.

After 10 days of continuous treatment, tumor inhibition rate was calculated and the expression of Survivin and Caspase-3 was detected by immunohistochemistry techniques. Results The tumor inhibition rates of 5-Fu group, XJLF formula high-dose group, XJLF formula medium-dose group, XJLF formula low-dose group and drug combination group were 55.03%, 56.38%, 41.23%, 23.09%and 60.28%respectively, and the tumor inhibition rate of drug combination group was significantly increased compared to the model control group(P<0.05), 5-Fu group(P<0.05)and XJLF high-dose group(P<0.05) Meanwhile, the Caspase-3 expression was significantly up-regulated and the Survivin expression was significantly down-regulated in drug combination group(Caspase-3 was 77 539.74±50 912.5, Suvivin was 35 709.1±10404.4)compared to the model control group(Caspase-3 was 18 464.71±7 537.01,Suvivin was 63 449.4±50 498.8), P<0.05 or 0.01, 5-Fu groupCaspase-3 was (47 198.89±10 751.2), Suvivin was(37 016.8±6 024.4), P<0.05 or 0.01and XJLF formula high-dose groupCaspase-3was (44213.57±7041.6), Suvivin was (38811.1±7313.0)respectively. Conclusion The tumor inhibition rate of drug combination group was higher than XJLF formula high-dose group and 5-Fu group. Also combination group hadstronger effect compared to model control group in terms of down-regulation of Caspase-3 expression and up-regulation of Survivin expression, which indicates a benefit ofXJLF and 5-Fu combination treatment.

Objective To examine the association of serum 25-hydroxyvitamin D levels with arterial stiffness and left ventricular hypertrophy (LVH) in elderly hypertension patients.Methods We recruited 166 elderly patients [mean age,(80.8 ± 6.2) years] with primary hypertension.Arterial stiffness was assessed by carotid femoral pulse wave velocity (cfPWV).Left ventricular mass index (LVMI) was determined according to the Devereux formula.Based on serum 25-hydroxyvitamin D levels,the patients were divided into two groups,the low 25-hydroxyvitamin D group (＜20 μg/L)and the high 25-hydroxyvitamin D group (≥20 μg/L).Results Faster cfPWV and larger LVMI values were observed in the low 25-hydroxyvitamin D group as compared with the high 25-hydroxyvitamin Dgroup [(15.00±3.04) m/s vs.(11.26±3.09) m/s;(120.14±25.82) g/m2 vs.(96.74±23.10) g/m2 ; t=-6.79,-5.16,respectively; both P=0.000].Multiple liner regression analysis showed that the 25-hydroxyvitamin D level was independently associated with LVMI (β=0.215,P=0.001) and cfPWV (β=-0.469,P＜0.001).Conclusions Serum 25-hyroxyvitamin D is independently associated with arterial stiffness,LVH Vitamin D may play an important role in the pathogenesis of arterial stiffness and LVH in elderly hypertension patients.

Objective:To observe the influences of Xuenaoxin capsule on the levels of endothelin(ET)and calcitonin gene-related peptide(CGRP)and neurological deficit extent in patients with acute cerebral infarction.Methods:A randomized, positive drug controlled clinical trial design was used,59 cases of acute cerebral infarction with qi stagnation and blood stasis syndrome were randomly divided into treatment group(30cases)and control group(29cases).The treatment group was treated with Xuenaoxin capsule,3 times a day,4 pills each time and the control group was treated with Nimodiping,3 times a day,20mg each time.Both groups had 14 days as a treatment course.The changes of levels of endothelin(ET)and calcitonin gene-related peptide(CGRP)in plasma as well as neurological deficit were measured and compared.Results:The plasma ET in treatment group (57.658?14.877)pg/L were significantly lower than those in control group(70.456?17.059)pg/L,but the plasma CGRP(84.404? 8.705)ng/L was higher than that in the control group(78.402?10.699)ng/L on the 14th day.The differences were both significant (P=0.0032,P=0.0213).The results showed that the total effective rate of Xuenaoxin capsule on improving clinical symptoms of patients with acute ischemic stroke was 76.67%and very superior to that of Nimodiping(P=0.0035).Conclusion:Xuenaoxin capsule could reduce neurological deficit extent,and improve the prognosis of patients with acute cerebral infarction by means of regulating ET and CGRP.

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.

OBJECTIVE To explore the role of P38MAPK inhibitor on the soft palate reconstruction of the rats with chronic intermittent hypoxia. METHODS The animals were divided into normal control group, hypoxia control group and SB203580+hypoxia group (every group 20 rats). After 5 weeks, the expressions of p38MAPK and p-p38MAPK protein on the soft palate of the rats were detected with immunohistochemical techniques and western blot. RESULTS Compared with the normal control group, the soft palate tissue thickness of the hypoxia group were increased most obviously; Levels of p38MAPK were increased in hypoxia control group; Compared with the hypoxia control group, the levels of p-p38MAPK group were decreased in SB203580+hypoxia group. CONCLUSION p38MAPK may play important roles in the soft palate reconstruction of the rats with chronic intermittent hypoxia.

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.
