OBJECTIVE: To study the influence of cyclosporine and tacrolimus on self-rated health in kidney transplantation patients with or without post-transplantation diabetes mellitus (PTDM). METHODS: Outpatients with kidney transplantation were divided into group with PTDM, group without PTDM, cyclosporine group and tacrolimus group according to mainly used immunosuppressant and patients with or without PTDM. Self-rated Health Measurement Scale (SRHMS) was applied for investigation. RESULTS: The level of physical health, psychological health and social health of kidney transplantation patients with PTDM were markedly lower than patients without PTDM (P

Objecfive To explore pathological mechanism and treatment of central hyponatrem-ia. Methods Synchronous assay was made to detect changes of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),endogenous digitalis-like substance(EDLS),antideuretic hormone (ADH),Na+ concentrations in blood and urine as well as osmotic pressure of plasma and urine in 68 pa-tients with traumatic brain injury(TBI). Results Of all,there were 27 patients with hyponatremia,mostly in patients with severe or critical TBI.There found syndrome of inappropriate secretion of antidi-uretic hormone(SIADH)in 7 patients and cerebral salt wasting syndrome(CSWS)in 20. Conclu-sions The central hyponatremia in patients with TBI may be related to the increased secretion of EDLS and ADH.The decrease of ANP and BNP in blood has no direct effect on Na+ concentration in blood.In-travenous injection of extrinsic thyrotropin releasing hormone(TRH)may inhibit dilutional hyponatremia resulted from increased secretion of ADH in TBI patients.

OBJECTIVEThis study aims to investigate the regulatory effects of calcitonin gene-related peptide (CGRP) on Nod-like receptor protein 3 (NLRP3) and interleukin-1β (IL-1β) to promote osteoblast differentiation.

METHODSDifferent concentrations of CGRP (0, 10, 30, 100 ng · mL⁻¹) were added to mouse osteoblasts in vitro. The mRNA and protein expression levels of both NLRP3 and IL-1β were examined using Real-time polymerase chain reaction and Western blot, respectively. Moreover, the concentrations of IL-1β protein and intracellular reactive oxygen species (ROS) were detected using enzyme-linked immunosorbent assay and flow cytometry, respectively. The osteogenic differentiation of mouse osteoblasts was identified through alizarin red staining.

RESULTSThe protein and mRNA expression levels of both NLRP3 and IL-1β significantly decreased (P < 0.05) with increasing CGRP concentration. Moreover, the contents of intracellular ROS gradually decreased (P<0.05). The osteogenic differentiation of the osteoblasts was more enhanced in the group treated with 100 ng · mL⁻¹ CGRP than in the empty group (0 ng · mL⁻¹ CGRP).

CONCLUSIONCGRP promotes osteoblast differentiation by inhibiting the expression of inflammatory factors.

Objective To evaluate the digital tomosynthesis in the diagnosis of occult bone fracture. Methods Both DR and DTS were performed in 135 cases with traumatic-induced pain. All the cases were suspected of bone fractures but with no abnormal findings in DR images. Two radiologists reviewed all the images and diagnosed in consensus. All cases were followed up and the imaging diagnoses were reviewed. Results Bone fractures or joint dislocations of 61 cases were shown in DTS images but not in DR images, including atlanto-axial fracture and subluxation in 7 cases, articular fracture of limbs in 20 cases, bone fractures of wrist, hand and foot in 11 cases, fractures of cervical, thoracic and lumbar vertebra in 7 cases, fracture of sacrococcyx in 8 cases, fracture of nasal bone in 4 cases, fractures of Sternum ,rib ,orbit and mandible in 1 case. Thirty-four cases with bone fractures were determined by using DTS in suspected cases and 17 cases were denied. Both DR and DTS images showed normal findings in 23 cases. Imaging diagnoses of all cases were consistent with the results of follow up. Conclusion DTS can depict bone fractures especially in the deep and complex bony structures, which may improve the diagnostic accuracy of bone fracture.

OBJECTIVEPrevious studies have clarified that calcitonin gene-related peptide (CGRP) can promote the biologi- cal activity of osteoblasts. To further reveal the role of CGRP in bone repair, we studied its influence on osteogenic differentia- tion of mouse bone marrow stromal cells (BMSCs) and initially explored the effect of the Hippo signaling pathway with this process.

METHODSBMSCs were induced to osteogenic differentiate osteoblasts by different concentrations of CGRP for a screening of the optimal concentration. CGRP was added in BMSCs, then the activity of alkaline phosphatase (ALP) and the number of mineralized nodules were examined by specific ALP kits after 48 hours and alizarin red staining fluid after 7 days, respectively. The protein expression of p-Mst1/2 was measured by Western blot. Verteporfin was used to block the downstream Yap signaling. The mRNA expression of collagen type I (Col I) and runt-related transcription factor 2 (Runx2) were detected by reverse transcription-polymerase chain reaction.

RESULTSCompared to the blank group, different concentrations of CGRP (10⁻⁹, 10⁻⁸, 10⁻⁷ mol · L⁻¹), especially 10⁻⁸ mol · L⁻¹, significantly increased the ALP activity of BMSCs (P < 0.05). Alizarin red staining also showed more mineralized nodules in 10⁻⁸ mol · L⁻¹ group. The expression of p-Mst1/2 increased in the CGRP group (P < 0.05). Verteporfin treatment effectively decreased the mRNA expression of Runx2 and Col I (P < 0.05).

CONCLUSIONThe Hippo signaling pathway plays a role in CGRP-induced osteogenic differentiation in mouse BMSCs.

Objective To discover radioresistance associated molecular biomarkers and its mechanism in nasopharyngeal carcinoma by protein-protein interaction network analysis.Methods Whole genome expression microarray was applied to screen out differentially expressed genes in two cell lines CNE- 2R and CNE-2 with different radiosensitivity.Four differentially expressed genes were randomly selected for further verification by the semi-quantitative RT-PCR analysis with self-designed primers. The common differentially expressed genes from two experiments were analyzed with the SNOW online database in order to find out the central node related to the biomarkers of nasopharyngeal carcinoma radioresistance. The expression of STAT1 in CNE-2R and CNE-2 cells was measured by Western blot.Results Compared with CNE-2 cells,374 genes in CNE-2R cells were differentially expressed while 197 genes showed significant differences.Four randomly selected differentially expressed genes were verified by RT-PCR and had same change trend in consistent with the results of chip assay. Analysis with the SNOW database demonstrated that those 197 genes could form a complicated interaction network where STAT1 and JUN might be two key nodes.Indeed,the STAT1-α expression in CNE-2R was higher than that in CNE-2 (t =4.96,P ＜ 0.05).Conclusions The key nodes of STAT1 and JUN may be the molecular biomarkers leading to radioresistance in nasopharyngeal carcinoma,and STAT1-α might have close relationship with radioresistance.

Objective To investigate the expression of CD133 mRNA in tissues of gastric cancer,and explore its relationship with clinicopathological features. Methods The tissues of gastric cancer and normal tissues adjacent to gastric cancer were obtained from 31 patients.The expression of CD133 mRNA was detected by semi-quantitative RT-PCR,and its relationship with clinicopathological features such as sex,age,tumor diameter,infiltration depth,TNM staging,tumor differentiation,lymph node metastasis and Ki-67 proliferation index was analysed. Results The relative gray scale values of CD133 mRNA in tissues of gastric cancer and normal tissues adjacent to gastric cancer were 0.378 3±0.141 1 and 0.038 1 ±0.091 9,respectively(P=0.000).The relative gray scale values of CD133 mRNA in tissues of gastric cancer with tumor diameter>5 cm were significantly higher than those with tumor diameter≤5 cm[(0.439 3±0.148 4)vs(0.334 3±0.121 2)](P=0.041),and those in tissues with lymph node metastasis were significantly higher than those without lymph node metastasis[(0.426 6±0.132 0)vs(0.239 5±0.030 9)](P=0.004).The rate of lymph node metastasis and the number of metastatic lymph nodes were positively related to relative gray scale values of CD133 mRNA(r=0.466,P=0.008;r=0.464,P=0.009).The relative gray scale values of CD133 mRNA in those with low expression of Ki-67 were significantly higher than those with high expression of Ki-67[(0.436 4±0.139 8)vs(0.316 4±0.117 4)](P=0.02),and expression of Ki-67 were negatively related to relative gray scale values of CD133 mRNA(r=-0.461,P=0.009).Conclusion The expression of CD133 mRNA in tissues of gastric cancer was associated with the rate of lymph node metastasis,number of metastatic lymph nodes and expression of Ki-67,which reflect the status of lymph node metastasis and proliferation of gastric cancer.

Objective To investigate the effects of Kruppel-like factor 6 (KLF6) on the apoptotic and migration ability of HepG2 cell, and the developmental role of KLF6 on zebrafish liver.Methods Constructed plasmid with shRNA-KLF6 was transfected in HepG2 and L-02.The impacts of loss of KLF6 on HepG2 was investigated by Western bolt, apoptosis analyses, cell cycle detection and scratch experiment;KLF6 morpholino oligonucleotides was microinjected into the Tg(lfabp:eGFP) transgenic zebrafish embryos.The morphant phenotype of the liver was imaged and the protein expression of KLF6 after knockdown of KLF6 was analyzed by Immunofluorescence staining.Results The expression of KLF6 in L-02 was significantly higher than in HepG2.After knockout of KLF6, KLF6 protein expression and apoptosis were significantly reduced.In addition, the cell cycle mainly stated in S phase and the migration ability of HepG2 was enhanced.After klf6 knockdown in transgenic zebrafish larvae, the development of zebrafish liver was delayed and KLF6 expression was obviously decreased in the liver.Conclusions The reduction of KLF6 expression increased the proliferation and migration ability, and reduced the apoptosis of HepG2.Loss of KLF6 affects the development of zebrafish liver, which may open a possibility to use zebrafish as a liver cancer model and for anti-liver cancer drug screening.

[Objective]To explore the efficacy of T2* mapping for evaluating inflammatory activity in the patients with Crohn disease(CD).[Methods]A total of 98 CD patients underwent MR enterographywith T2*WI. T2* values were measured by put-ting regions of interest on the thickening bowel wall on T2*mapping. The activity of bowel segment was scored by magnetic resonance index of activity(MaRIA),to analyze the relationship between T2*values with CD activity.[Results]A total of 160 bowel segments were evaluated and includedinactive(MaRIA<7,n=26),mild(7≤MaRIA<11,n=23),and moderately-severe(MaRIA≥11, n = 111)active lesions. The differences in T2* values amongthese three groups were significant(all P < 0.05). T2* values of 160 bowel segments correlatedclosely withMaRIA(r=0.743,P<0.05). High accuracy of T2*values was shown for differentiating inac-tive from active CD(AUC=0.877)anddifferentiating inactive-mild from moderate-severe CD(AUC=0.848). The threshold T2*value of 20 ms allowed differentiation of mild from moderate-severe CD with74.5%sensitivity and 84%specificity.[Conclusions]T2*values, as thequantitative indexof T2*mapping,correlate well with CD activity and showsatisfiedefficacy for diagnosing inflammatoryactivity.
