Forty-two patients with type 2 diabetes mellitus (DM) were refered to 3 groups:type 2 DM without diabetic nephropathy (DN),type 2 DM with DN in the initial stage and type 2 DM with DN in the clinical stage.Ten healthy subjects were served as control group.Plasma adrenomedullin (ADM),urinary?_1- microglobulin (MG) and?_2-MG were detected.The results showed that the level of plasma ADM rose gradually with the development of DN and was positively correlated with markers of tubulointerstiial injury such as urinary?_1- MG and?_2-MG (both P

Objective To investigate the anti-tumor effect of ZM-66 on multidrug-resistant leukemic cell line K562/ADM.
Methods The K562/ADM cells were treated with varying concentrations (0, 1, 2, 4×10-3 mmol/L) of ZM-66 or etoposide for 24 hours. The proliferation was detected by Sulforhodamine B Sodium Salt (SRB) assay and apoptosis was detected by flow cytometry analysis and fluorescent staining. In addition, the expression levels of p53 and bax genes in K562/ADM cells were detected by RT-PCR analysis. The level of P-glycoprotein (P-gp), P53 and Bax protein in K562/ADM cells were detected by Western blot assay.
Results SRB assay demonstrated that etoposide had little inhibitory effect on K562/ADM cells, whereas ZM-66 (1, 2, 4×10-3 mmol/L) had significantly inhibitory effect on K562/ADM cells (all P<0.01). The acridine orange/propidium iodide dual staining showed that there were typical condensation of chromatin and nuclear fragmentation nuclei with red color in ZM-66 treated cells. Flow cytometric analysis showed that there was a significantly increase of apoptotic cells in K562/ADM cells after treated with ZM-66. RT-PCR showed that the p53 and bax mRNA expression levels in K562/ADM cells treated with ZM-66 at 1, 2, 4×10-3 mmol/L were higher than those in the cell without treatment. Western blot showed that the P53 and Bax protein expression levels in K562/ADM cells treated with ZM-66 at 2, 4×10-3 mmol/L were higher than those in the cell without treatment. But the P-gp protein expression level in K562/ADM cells treated with ZM-66 at 2, 4×10-3 mmol/L was gradually lower than those in the cell without treatment.
Conclusion ZM-66 is able to induce cell death by apoptosis in vitro, as a result of the reverse of the apoptosis resistance in drug-resistant K562/ADM cells by modulating expression of key factors associated with apoptosis induction.

Good prenatal and postnatal care and good preschool education are important approaches to raise the diatheses of population for the chinese nation. This article suggests that the cell phone platform can be used to communicate with each other among the hospitals, the government and the common people, through which the useful informations could be transmitted to the relative persons in time. It's also a new way for propaganda of family planning. This article introduces the structure of the system, the creation of the expert database, and the connection to the telecommunication system.

Objective To investigate surgical opportunity and suitable treatment approach in nodular Hashimoto's disease.Methods An analysis was performed in 388 pathologically confirmed cases with nodular Hashimoto's disease and other thyroid-related diseases.All the cases were involved with surgical treatment due to thyroid nodules from June,1995 to Dec,2005.Results Among the above-mentioned cases,64 cases (16.5%) were Hashimoto's disease with the presence of thyroid cancer,190 (48.9%) nodular thyroid tumor,94 (24.2%) thyroid adenoma,7 (1.8%) hyperthyroidism,the rest (8.5%) simple Hashimoto's disease.Prior to 2000, among 106 cases of Hashimoto's disease there were 15 cases accompanied by thyroid cancer.Since 2001,282 cases of Hashimoto's disease were dealt surgically,49 of which had thyroid cancer.Compared to the period from 1995 to 2000,the complication of Hashimoto's disease and thyroid cancer has been sharply increasing during the recent five years (P

ObjectiveTo study the variant differentiated phase of the human bone marrow stromal cell (MSC) during induced adipogenesis course by morphological observation.MethodsAfter proliferated in vitro, MSCs isolated from bone marrow of the female adults volunteers were cultured with the adipogenetic inducers for 6—30 days. Morphological changes of the cells were observed everyday under Olympus contrast phase microscopy, and some specimens were stained with Oil-red-O.ResultsMSC showed long spindle shape before inducing, and then changed gradually to oval or round shape and the figure enlarged simultaneously. There were specifically morphological changes with lipid droplet emergence under plasmalemma and confluence gradually to lipid drop during differentiated into the phase of immature and mature adipocyte.ConclusionIt is easy to detect the MSC differentiated into the phase of immature and mature adipocyte with the specific morphological change of lipid droplet, while in the phase of preadipocyte and adipoblast, there is no special morphological change, and it may need some specific markers to detect.

Objective To investigate the features of low grade dysplastic nodule(LGDN)and high grade dysplastic nodule(HGDN)in cirrhotic liver on the baseline ultrasound(BUS)and contrast-enhanced ultrasound (CEUS).Methods Seventeen LGDNs and 16 HGDNs which were pathologically proved underwent baseline and CEUS examination.CEUS was performed with contrast pulse sequence(CPS)and contrast harmonic imaging (CHI)and used SonoVue as contrast agent.Results Significant differences(all P>0.05)were not shown between LGDN and HGDN for manifestations on both the BUS and CEUS.After contrast agent injected, hyperenhancement in arterial phase and hyper-or iso-enhancement in late phase,hypo-enhancement in early arterial phase and iso-enhancement through late arterial,portal and late phase,hyper-enhancement in arterial phase and hypo-enhancement in late phase,iso-enhancement in arterial,portal and late phase,iso-enhancement in arterial phase and hypo-enhancement in late phase were showed in 10(30.3%),10(30.3%),8(24.3%),4(12.1%),1(3.0%)cases of DN, respectively.Conclusions LGDN and HGDN displayed similar feature on both the BUS and CEUS.There were complicated manifestations of DN on the CEUS and the main contrast-enhanced sonographic feature of DN was,different from regenerative nodule and hepatocellular carcinoma.CEUS was helpful in diagnosing DN in cirrhotic liver.
