Early diagnosis and timely treatment of hepatic steatosis is very important for controlling the development and improving the prog-nosis of disease.This paper introduces the controlled attenuation parameter (CAP),a novel non -invasive method to quantitatively assess hepatic steatosis.This paper briefly describes the advantages of CAP compared with other methods for detecting hepatic steatosis:CAP is simple,fast,repeatable,and generally accepted by patients.CAP is of great value for early detection of fatty liver.Moreover,this paper re-views the optimal cut -off values of CAP for detection of fatty liver in different studies.CAP can be used to dynamically monitor the progres-sion and regression of fatty liver as a guide to clinical treatment.

Most neonatal diabetes mellitus (NDM) is caused by genetic abnormality. Sulfonylurea (SU) has been successfully applied in NDM patients;The pathogenesis of NDM and mechanism of sulfonylurea on molecular level have been illuminated, and recent studies revealed that glycated albumin is a useful glycemic indicator. In this review, the research progress of NDM is summarized.

Objective To investigate the changes of T cells and disease development in the mice with Smad3 deficiency in the bone marrow cells.Methods Bone marrow cells obtained from Smad3 null(Smad3~(-/-))mice and wild type(Smad3~(+/+))mice were injected to Co~(60)-irradiated GFP mice,respectively.The general states of the bone marrow recipients were observed.The mice were sacrificed at the sixth week and the histopathological changes in the intestines were examined.The changes of T cells from lymph nodes were detected by flow cytometry.Results Smad3~(-/-) bone marrow recipient mice appeared a wasting syndrome and intestinal inflammation.The amount of CD4~+ CD62L~(lo) T cells in lymph nodes was significantly increased.Conclusion These results indicate that the mice with Smad3 deficiency in the bone marrow cells present an inflammatory disorder and their T cells are activated.

BACKGROUND:The large watercress molded piece is longer than that of the normal molded piece, which is suitable for dental restoration of elderly patients with gingival recession and relatively long crown.
OBJECTIVE:To test and verify the effect of large watercress molded piece on the auxiliary repair of approximal caries lesions in molars of the elderly.
METHODS:Eighty-seven senile patients with molar approximal caries were randomly divided into two groups: those were repaired by large watercress molded piece as experimental group, and those repaired by traditional amalgam molded piece ascontrol group. Then we compared the comfortable satisfaction rate, the excelent and good rate of repair and the gingival index between the two groups immediately, 1, 3, 6 and 12 months after repair.
RESULTS AND CONCLUSION:The comfortable satisfaction rate of the experimental group was significantly higher than that of the control group at 1, 3, 6 and 12 months after repair (P< 0.05), and the gingival index was significantly lower than that of the control group (P< 0.05). The excelent and good rate of the experimental group was significantly higher than that of the control group at different time points after repair (P< 0.05). No loss or fracture of the restorations occurred in the two groups. These results demonstrate that the large watercress molded piece for repairing approximal caries lesions in molars of the elderly can better restore the anatomical shape and approximal points of teeth, and reduce food impaction and gingival inflammation.

Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

BACKGROUND: As a kind of filling material for wedge-shaped defects, GC Fuji Ⅸ glass-ionomer cement has arose more and more attention. However, the comparison of repair results between GC Fuji Ⅸ glass-ionomer cement and reinforced glass-ionomer cement are poorly understood. OBJECTIVE: To compare the clinical effect of GC Fuji Ⅸ glass-ionomer cement and reinforced gtass-ionomer cement for repairing wedge-shaped defects of old people. METHODS: Totally 80 teeth were randomly divided into 2 groups, and filled by GC Fuji Ⅸ glass-ionomer cement (experimental group) and reinforced glass-ionomer cement (control group), respectively. The clinical effect of 2 materials were evaluated on color match, edge density heterozygosity, restoration integrity, occurrence of secondary caries and pulp symptom at immediately, 3 months, 6 months and 1 year after placement. RESULTS AND CONCLUSION: The color match of the experimental group was better than that of the control group at 3 months, 6 months and 1 year after placement (P < 0.05); and the edge density heterozygosity of the experimental group was superior to the control group at 6 months and 1 year after placement (P < 0.05); in addition, the restoration integrity of the experimental group was surpass the control group at 1 year after placement (P < 0.05). It demonstrated that GC Fuji IX glass-ionomer cement is an ideal choice for wedge-shaped defects of old people, which exhibits superior effects to reinforced glass-ionomer cement in 1-year follow-up.

AIM: To examine the inhibition of matrix metalloproteinase (MMP) activity by doxycycline (Doxy) and its effect on vascular smooth muscle cells (SMCs) proliferation, neointimal hyperplasia and vascular remodeling. METHODS: The model of rat common carotid artery injury was established by balloon-dilatation. Doxy was administered to the animals of treatment group at dose of 30 mg?kg -1?d -1. The activity of MMPs in the tissue of injured carotid arteries was measured by gelatin zymography. The thickness and area of neointimal, lumen area and the proliferation of SMCs were measured by histological and morphometric analysis. RESULTS: 1. After Doxy treatment, the activity of MMP-9 in the carotid arteries was reduced by 26.3% and 34.5% compared to that in rats without Doxy treatment at 24 hours and 3 days after balloon injury, respectively (P

ObjectiveTo investigate the value of CEUS in differential diagnosis of benign and malignant thyroid solid lesions.MethodsTotally 45 patients with thyroid solid lesions underwent CEUS examination.The enhancement mode and blood perfusion characteristics of malignant and benign lesions were analyzed,and the results were compared with pathology.ResultsCEUS diagnosed 31 benign lesions and 14 malignant masses.The diagnostic accordance rate of CEUS was 93.75％ (30/32) and 92.31％ (12/13) for benign and malignant lesions respectively.In 31 benign lesions,27 (27/31,87.10 ％) showed entire homogeneous enhancement,4 (4/31,12.90％) presented inhomogeneous enhancement.In 14 malignant masses,1 (1/14,7.14 ％) showed homogeneous hypoechoic enhancement,12 (12/14,85.71％) presented inhomogeneous hyperechoic enhancement and 1 (1/14,7.14％) presented non-enhancement.ConclusionCombined with two-dimensional grey scale ultrasound and CDFI,CEUS enables dynamic observation of the microvascular perfusion of thyroid lesions,therefore helps to differentiate benign and malignant thyroid lesions.

Objective: To investigate the suppressive effects of nedaplatin on human liver cancer cell line SMMC7721 and the interactions between nedaplatin and adriamycin or mitomycin or fluorouracil. Methods: The cytotoxic index of nedaplatin alone or combined with other chemotherapy agents on SMMC cells were detected by MTT method. Results: SMMC was sensitive to nedaplatin with a positive correlation between cytotoxic index and nedaplatin concentration. There were significant synergism in the cytotoxic effects of nedaplatin combined with adriamycin or Mitomycin or Fluorouracil on SMMC cells. Conclusion: Nedapltin is a promising agent in the treatment of human liver cancer.
