MRI of four categories of avascular necroses appeared as phase Ⅰ:line-like low signal of weight-bearing area of femoral head on T1WI, high signal on T2WI as the main change. Phase Ⅱ:clear boundary crescent-shaped uneven signal on T1WI, T2WI displayed moderately higher, uneven slightly lower signal around, showing a typical two-line sign. Phase Ⅲ:femoral head deformation, subchondral fracture, col apse, crescent formation, zonal low signal on T1WI, medium or high signal on T2WI. Phase Ⅳ, Ⅴ:complete destruction of articular cartilage, joint space narrowing, significant col apse and deformation of the femoral head, non-specific secondary osteoarthritis of the acetabulum, such as sclerosis, cystic degeneration and marginal osteophyte. The X-ray, CT, MRI performances of four types of avascular necroses at the same period were basical y the same.

Objective To explore the feasibility of C14-urea breath test in the diagnosis of child chronic cough.Methods One hundred and twenty children cases of chronic cough were collected as the research subjects and divided into the C14 group(adopting C14-urea breath test for diagnosis) and combined group(C14-urea breath test combined with routine diagnostic method) according to different diagnostic means,60 in each group.Then the positive diagnostic rate and effectiveness were analyzed and compared between the two diagnostic methods.Furthermore the ROC curve was adopted to evaluate its diagnostic value.Results The positive diagnosis rate in the C14 group was 76.67%,which was significantly lower than 95.00% in combined groups,the difference was statistically significant (P<0.001).The sensitivity and positive predictive value in the combined group were obviously higher than those in the C14 group (P<0.01),but there were no statistically significant differences in specificity and negative predictive value between the two methods (P>0.05).The expression levels of serum hs-CRP and IL-6 in the C14 group were significantly higher than those in the combined group,but the expression level of IL-10 was obviously lower than that of the combined group (P<0.05).The AUC in the ROC curve of combined group was significantly higher than that of the C14 group(P<0.05).Conclusion The C14-urea breath test can serve as a supplementary diagnosis means in child chronic cough,and its combining with the routine diagnosis method can significantly increase the diagnosis effectiveness.

objecive To chrify clinical characteristics and outcme of acute/subacute interstitial pneumonia(A/SIP)in patients with dermatomyositis.Methods The elinical data of 10 dermatemyositis patients accompanied with A/SIP who hospitalized in April 2006 to April 2008 were reviewed.Data of 9 dermatomyesitis patients with non-A/SIP interstitial lung diseases treated during the same period were also documented for the comparison.The survival rate of patients wag statistically analyzed.Results Compared with those dermatomyositis patients with non-A/SIP interstitial lung diseases,patients with A/SIP had shorter disease courses and higher incidences of fever,heliotrope rash and ground glass opacity in CT image(P＜0.01or＜0.05).However,the levels of serum creatine kinase tended to be normal.After following up 6 months,only 1 patientwithA/SIP survived(P=0.0001).Logistic regression analysis showed the combination treatment of hormonal,cyclophosphamide and cyclosparine might prolong the survival time(P=0.107).Conclusions A/SIP with dermatomyositis is a fatal disease which needs to be early diagnosed and treated.Patients having dyspnea or breathless in the early stage,especially those with recurrent fever,heliotrope rash and normal serum creatine kinase is predicted to develop A/SIP later.A better outcome may be achieved when treating the patients with stemids plus cyclophosphamide and cyclosporine.

Objective To investigate the role of the extracellular signal-regulated kinases 1 and 2 (ERK1/2) in rotenone-mediated dopaminergic cell damage. Methods Neuronal rat adrenal pheochromecytoma(PC12) cells treated with rotenone were used as the cell model of Parkinson' s disease (PD). Cell viability of PC12 cells after exposure to rotenone was detected by MTT (methyl thiazolyl tetrazolium) method. Immanohistechemistry was used to detect the phosphorylation of ERK1/2 in cells exposed to rotenone. Western blotting was used to verify the phosphorylation of ERK1/2 and to observe the effect of PD98059, an inhibitor of the upstream mitogen activated protein kinase kinase (MEK) that phosphorylates and activates ERK1/2, on rotenone-induced ERK1/2 phosphorylation and cell viability.Results The viability (represented by A570 of PC12 cells exposed to 5 μmoL/L rotenone) declined with the increase of exposure time from 1 h to 24 h (%, 1 h :75.46±5.47, 2 h : 70.42±1.94, 4 h : 65.23± 0.96, 8 h : 59.04 ± 2.85, 24 h :29.64 ± 1.63, comparison between different time points(F=143.014, P=0.000) ; compared with control groups(100.00±2.89), q value: 17.07, 20.58, 24. 19, 28.50, 48.95 respectively, all P <0.01). After exposure to rotenone, phosphorylated ERK1/2 aggregated in the PC12 cells. Western blotting indicated that rotenone induced a biphasic phosphorylation of ERK1/2, which increased from 30 min after rotenone treatment, reached the peak at 1-2 h, decreased at 4 h, and increased again at 8 h, and disappeared after 16 h; PD98059 significantly inhibited ERK1/2 phosphorylation induced by rotenone, and attenuated cell injury examined at 1, 2 and 8 h. Conclusions Our study suggested that ERK1/2 activation plays a detrimental role in rotenone toxicity, and raised the possibility that abnormal patterns of ERK1/2 activation may contribute to dopaminergic neuronal cell death in PD.

Microwaves can be directly transformed into heat inside materials because of their ability of penetrating into any substance. The degree that materials are heated depends on their dielectric properties. Materials with high dielectric loss are more easily to reach a resonant state by microwaves field, then microwaves can be absorbed efficiently. Microwave irradiation technique with the unique heating mechanisms could induce drug-polymer interaction and change the properties of dissolution. Many benefits such as improving product quality, increasing energy efficiency and reducing times can be obtained by microwaves. This paper summarized characteristics of the microwave irradiation technique, new preparation techniques and formulation process in pharmaceutical industry by microwave irradiation technology. The microwave technology provides a new clue for heating and drying in the field of pharmaceutics.
