BACKGROUND: p38 mitogen-activated protein kinase signal transduction pathway is a member of the mitogen-activated protein kinase family. It plays an important role in the development of osteoarthritis. OBJECTIVE: To review the progress of p38 mitogen-activated protein kinase signal transduction pathway in the pathological process of osteoarthritis. METHODS: An online search of CNKI and PubMed databases was performed for articles using keywords of “p38 mitogen-activated protein kinase signal transduction pathway, osteoarthritis, articular cartilage, chondrocyte” in Chinese and English, respectively. Relevant articles were summarized from three aspects of introduction of p38 signal transduction pathway, the role of p38 mitogen-activated protein kinase signal transduction pathway in osteoarthritis and the inhibitor of p38 in osteoarthritis. A total of 90 articles were included. According to inclusion criteria, a number of 46 articles were retained at last. RESULES AND CONCLUSION: p38 mitogen-activated protein kinase signal transduction pathway has a close relation with chondrocyte hypertrophy and calcification, chondrocyte apoptosis, synthesis of cartilage matrix metal oproteinase, production of proinflammatory cytokines, and exerts a significant effect on the development of osteoarthritis. p38 mitogen-activated protein kinase is involved in the formation and development of osteoarthritis through a variety of complex mechanisms and plays a very important role. Therefore, blocking p38 mitogen-activated protein kinase signaling pathway may be a new target in the treatment of osteoarthritis.

Objective To evaluate the value of CEUS in dynamicly assessing the blood perfusion of hepatic alveolar echinococcosis (HAE) in rats.Methods The experimentally induced secondary HAE in totally 70 rats were studied at different time periods (gth week,28th week,and 50th week) with CEUS,and compared to pathology results.Results At the 9th week,55 HAE lesions (55/70,78.57％) presented hyperechoic and the rest of 15 HAE lesions (15/70,21.43％)presented mixed echogenicity.The single or multiple vesicular structures were found as pathological feature.At later stages (28th week and 50th week),the size of lesions increased compared to 9th week with more solid structures and the calcifications found in HAE lesions.Microscopically,the fibrous tissues surrounding the lesions gradually thickened and the microvascular accumulation were visible around the lesions.The HAE lesions at the 9th week showed the ring enhancement and central septa enhancement in CEUS.The HAE lesions at the 28th week and 50th week showed combinations of no enhancement,ring enhancement,and central septa enhancement in CEUS.The ratio of edge enhancement to maximum diameter of lesions decreased with the progression (P=0.02).Conclusion The ultrasonographic features in HAE lesions become more complicated with increasing calcifications and enlarged necrosis areas with the progression.The CEUS can reveal the dynamics of blood perfusion of HAE lesions at different stages.

Objective To analyze the multi-slices spiral CT (MSCT) findings of hepatic alveolar echinococcosis(HAE), and to evaluate the value of MSCT for diagnosis of HAE. Methods Twenty-six cases with HAE were scanning by MSCT. The raw data were transmitted to advanced workstation for reconstruction imaging. Correlated studies were made between the CT features and pathology or other imaging results. Results Altogether 28 lesions were detected. They all revealed as heterogeneous hypodense mass with ill-defined boundary in plain CT but were easily being distinguished from surrounding parenchyma after contrast medium injection.Characteristics of the lesions include different amount of calcification (26/26), liquefied necrosis in center area (20/26), peripheral lacunae or alveolar signs (15/26), compensatory hypertrophy of healthy hepatic part (18/26) and the retraction in the involved hepatic lobe or segment (12/26). The lesions that located at or extended to hepatic hilum caused dilatation of intra-hepatic biliary ducts(9/26), splenomegaly (12/26), and ascites (1/26). MSCT angiography (CTA) depicted signs of abnormalities of hepatic vessels such as compression, displacement, encasement and occlusion. Compared with findings of operation, the sensitivity, specificity and positive prediction value of CTA for evaluating the hepatic artery system disorders were 88%, 96% and 93%, respectively; and for portal venous system were 95%, 100% and 95%, respectively; while for hepatic venous system were 96%, 86% and 96%, respectively. Conclusion MSCT is able to comprehensive display the CT features and vessels complication of HAE. It provides reliable imaging for both accuracy diagnosis and proper treatment of the disease.

Objective To explore the accuracy and feasibility of dual-source CT(DSCT)in evaluating the left ventricular function compared with echocardiography.Methods 30 cases of coronary heart disease were continuously collected in our hospital ,and dual-source CT and echocardiography were examined in a week.Left ventricular function parameters (LVEDV,LVESV,LVSV)were measured,and paired sample t test was compared to show whether there was any difference between the two methods,Rates betweengroups were compared with Chi-square test,Pearson correlation analysis method was applied to calculate the correlation between the two methods.Results There was no statistically significant difference for LVEDV,LVESV,LVSV,LVEF parameters between the two methods (t test,P >0.05).By Pearson test,the correlation coefficient was r=0.770-0.938(P <0.05),in which the high relation between the two methods was showed.Conclusion A strong accuracy of dual-source CT in evaluating left ventricular function is demonstrated.Dual-source CT angiography is a noninvasive assessment of coronary tree,whereas the analysis of the left ventricular parameters provides additional information of cardiac function without further radiation exposure or scan time,which can provide a more intuitive and system information for clinical.

Objective To discuss the prenatal ultrasound manifestations of Apert syndrome. Methods The prenatal ultrasound features of 4 fetuses identified as Apert syndrome after detailed antenatal ultrasound examinations between January, 2010 to Februry, 2014 in our hospital were analyzed. The ultrasound images and postnatal outcome or autopsy were compared to analysis the sonographic features of Apert syndrome in prenatal. Results The prenatal ultrasound characteristics and pregnant outcome of the 4 fetuses were showed as followings:(1) Skull deformity:4 fetuses were all appeared as acrocephaly, coronal suture premature close and frontal protrusion, while 3 cases (case 1-3) had“clover leaf skull deformity”features. (2) Midfacial malformation deformity:3 cases (case 1-3) were all with hypertelorism and mid-sagittal facial proifle abnormal and only 1 case (case 2) had nose hypoplasia. (3) Limbs abnormal:4 cases were all appeared as bilateral symmetry syndactyly of hands and 1 case (case 2) was diagnosed as bilateral symmetry syndactyly of feet. (4) Associated abnormality:persistent right umbilical vein in 1 case (case1), thoracic spine stenosis in 1 case (case 2), hyperechogenic renal parenchyma in 1 case (case 3) and left-diaphragmatic hernia in 1 case (case 4). (5) The pregnant outcome:3 cases underwent pregnancy termination and 1 case was labored at term. The 3 cases (case1-3) were diagnosed as bilateral symmetry syndactyly of feet after induced labor. The cleft palate and bilateral symmetry syndactyly of feet were misdiagnosed in the full-time infant (case 3), who was died two days after birth. Conclusions The Apert syndrome is a rare syndrome. It generally has typical characteristic of prenatal ultrasound, such as coronal suture premature close, acrocephaly, mid-sagittal facial profile abnormal and bilateral symmetry syndactyly of hands and feet. Prenatal diagnosis of Apert syndrome can play an important role in genetic counseling and postnatal treatment.
