ABSTRACT
Objective To investigate and compare predictive diagnostic value of neutrophil-to-lymphocyte ratio,platelet-to-lymphocyte ratio and mean platelet volume,for early-stage diabetic nephropathy (EDN).Methods 245 patients with T2DM were divided into patients with EDN(EDN group,n=120) and patients without DN (T2DM group,n=125).116 healthy people were also enrolled in our study.Their clinical and biochemical data were collected.Results NLR (2.14±0.73 vs 1.78±0.58 vs 1.46±0.48,P＜0.05),PLR (116.11±36.43 vs 100.65±27.83 vs 90.24±26.17,P＜0.05) and MPV (11.29± 1.16 vs 10.37 ± 1.01 vs 9.78 ± 1.28,P＜0.05) were significantly higher in EDN group and T2DM group than those of the control group.NLR,PLR and MPV were significantly higher in EDN group than those of T2DM group.Logistic regression analysis showed that after correction of diabetes duration,blood pressure,lipid,and so on,NLR(OR=3.77,95％ CI 2.12-6.08,P＜0.01),PLR(OR=1.81,95％ CI 1.02-2.89,P=0.04) and MPV (OR=2.08,95％ CI 1.22-5.04,P=0.01) were all positively correlated with EDN.According to the analysis of ROC curves,the value of NLR for predicting EDN was higher than PLR and MPV.The cut off value of NLR for predicting EDN was set at 1.82,with the sensitivity of 79.20％ and the specificity of 68.60％.Conclusion NLR has the greatest diagnostic value for EDN,patients whose NLR is over 1.82 need further test in order to diagnose and therapy DN earlier.
ABSTRACT
Objective To explore the MRI features about the annular ligament injuries in pediatric patients. Methods The appearance of MRI about annular ligament injuries in 15 pediatric patients diagnosed clinically were retrospectively analyzed. All patients (aged 4 years 8 months to 12 years 11 months) were scanned by MRI in 2-4 days after injury. Patients were divided into three groups according to the annular ligament injuries severity, which were simple annular ligament injuries, annular ligament injuries combined dislocation, annular ligament ruptures combined dislocation. Results Simple annular ligament injuries were showed in 2 cases, which appeared high signal but continuous configuration. Annular ligament injuries combined dislocation were showed 9 cases. Bald head sign, thickening and continuous ligment were found on axial image, together with compression of the radial joint space on sagittal and coronal view. Annular ligament ruptures combined dislocation were showed in 4 cases. The ligment showed"bald head sign", tortuosity and uneven thickening on axial view and compression of the radial joint space on sagittal and coronal view. Combining with the other tissue injuries were detected in 15 cases. Conclusion The annular ligament injuries show some MRI characteristics. Bald head sign is specific in the annular ligament injuries of pediatric patients.

ABSTRACT
<p><b>OBJECTIVE</b>To clarify the related factors of marginal bone loss (MBL) around tissue level implants in the posterior part of the mandible.</p><p><b>METHODS</b>A total of 116 tissue level implants were implanted in the mandibular posterior region of 76 patients. Patients' information, including general characteristics, implant characteristics, implant site characteristics, and prosthesis characteristics, was recorded. Their cone beam computed tomography data were measured immediately after implant placement, 3 months later, and 3 and 12 months after prosthesis loading. The measurement of MBL was conducted by One Volume Viewer software. SPSS 20.0 was used for statistic analysis.</p><p><b>RESULTS</b>Smoking, cortical bone thickness (CBT), collum angle (CA), and implant local sanitation showed significant differences with body mass loss (P<0.05). No significant differences were found among sex, age, length of implant, diameter of implants, implant systems, bone height, prosthesis type, and MBL (P>0.05).</p><p><b>CONCLUSION</b>The risk factors that caused MBL were smoking, thicker CBT, larger CA, and poor implant local sanitation. Among them, poor implant local sanitation had the highest correlation with MBL.</p>

Purpose To explore the effect of Levothyroxine on spatial working memory in patients with subclinical hypothyroidism (SCH) using blood oxygenation level dependent-functional MRI (BOLD-fMRI). Materials and Methods Sixteen patients with SCH before and after 6 months levothyroxine (LT4) treatment and 16 matched euthyroid volunteers underwent n-back task fMRI scanning. AFNI software was used for localization and quantification. Results All the subjects demonstrated activated areas including bilateral dorsolateral prefrontal cortex (DLPFC), bilateral premotor area (PreMA), supplementary motor area/anterior cingulate cortex, bilateral parietal area (PA) and right caudate nucleus/thalamus, with right hemisphere dominance. Quantitative analysis of regions of interests showed that all these regions had load effect related to memory load in the control group (P<0.001), whereas only left DLPFC, left PA, bilateral PreMA and right caudate nucleus/thalamus showed the same effect in SCH group. After 6-month treatment with LT4, BOLD signal change was observed in SCH patients within the right DLPFC, right PA and anterior cingulate/supplementary motor cortex (P<0.001). The activation intensity of working memory related brain regions was lower in SCH group compared with that of the control group. Conclusion Spatial working memory impairments in SCH patients are likely related to decreased right DLPFC and right posterior parietal function. LT4 replacement therapy is important to improve and reverse the memory impairment.
