ObjectiveTo study the characteristics of nonfunctioning parathyroid cysts (NFPTC) for its diagnosis and treatment.Methods 5 cases of NFPTC were hospitalized during 1985～1999. The clinical features, serum calcium evaluation ultrasonography and nuclide scanning were performed. Postoperative pathologic and immunihistochemistry detection in NFPTC were made.ResultsTumours in the 5 cases were removed by operation and diagnosis was verified by pathology. Tumors were all positive for chromogranin A (CgA),synaptophysin(Syn),and neuron specific enolase(NSE). Follow up found no recurrence. ConclusionsSurgical resection is most effective in treating NFPTC and diagnosis is made by pathologic examination.

ObjectiveTo observe the effect of family rehabilitation plan (FRP) on motor function of stroke patients with hemiplegia.Methods64 patients were randomly divided into the FRP group (32 cases) and control group (32 cases). The patients in the FRP group critically followed the schedule and activities scheduled on FRP and were assessed and guided in out-patient department every two weeks. The patients in the control group made schedule and carried on activities by themselves. Motor function was assessed with Fugl-Meyer Assessment (FMA) and modified Barthel index (MBI) respectively.ResultsMotor scores of the patients in two groups significantly increased after treatment ( P<0.001), and that of the FRP group was significantly better than that of the control group ( P<0.001).ConclusionThe FRP can significantly improve motor function of stroke patients with hemiplegia.

Objective To investigate the bone marrow supernatant expression of sclerostin in the patients with multiple myeloma (MM) and to clarify its clinical signification .Methods The sclerostin level was quantified by using ELISA ,and the gene expression of sclerostin was determined by RT-PCR .Results The sclerostin level was (0 .54 ± 0 .21)pg/mL in the MM group ,which was sig-nificantly higher than (0 .31 ± 0 .06)pg/mL in the control group (t=5 .67 ,P<0 .01) .The sclerostin level was (0 .65 ± 0 .17) pg/mL in the recurrent and refractory MM group ,which was significantly higher than (0 .47 ± 0 .21) pg/mL in the control group and the newly diagnosed group (t=8 .44 ,3 .27 ,P<0 .01) ,RT-PCR verified that the BMMNC of most patients expressed sclerostin gene .The expression of sclerostin in the MM group was negatively correlated with alkaline phosphatase (ALP)(r= -0 .379 ,P=0 .005) ,and positively related with the correction blood calcium ,bone loss points ,serum β2-micro globulin(β2-GM ) ,proportion of serum M protein and clinical International Staging System (ISS) stages .The median follow-up periods were 29(6-65) months ,the low sclerostin group had the median survival period of 48(6-65) months and the high sclerostin group had the median survival pe-riod of 24(6-52) months ,the difference between them had statistical significance (χ2 = 12 .74 ,P< 0 .01) .Conclusion Its level may reflect the bone destruction ,osteogenesis inhibition degree and myeloma burden ,and reflect the median survival period of MM patients to some extent .

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 research effect of different doses of Changle on the structure and function of rat liver.Methods: 180 healthy Wistar rats were divided into 5 experimental groups according following doses: 0.1,0.2,2.0,10.0 and 20.0 mg*kg-1,respectively, and the control group given physiological saline for six months. The changes of liver structure were examined by means of normal histological chemistry and transmission electron microscope(TEM). Results: The body weight of animal was linearly increased with the decrease of administered doses, gradual reduction of glycogen in hepatocytes and infiltration of inflammatory cells in the portal area were found in the group of 20.0 mg*kg-1. Changes of ultrastructure showed there were dense bodies and lysosomes containing dense granules in Kupffer cell and hepatocyte,and they were increased along with doses adding. Nuclei deformed, ALP and GPT in serum were rose in the group of 20.0 mg*kg-1. Different doses of Changle could lead to distinct biological effects. Conclusion: Long-termed administration of 20.0 mg*kg-1 Changle can lead to damage of structure and function of rat liver.

This review elucidates the non-immune factors including islet purification, instant blood-mediated inflammatory response and revascularization deficit on the development of islet transplantation, and also highlights the application and perspective of islet xenotrasplantation in the treatment of diabetes.

Objective To explore the changes and significances of platelet granule membrane protein-140 (GMP-140),GMP-140 in plasma,PAdT and PAgT in patients with acute cerebral infarction.Methods The platelet GMP-140 was measured with enzyme-linked immunosorbent assay (ELISA) competitive method and GMP-140 in plasma by ELISA double antibody method in blood collecting in 3 d and 2 weeks after onset in large(n=22),small(n=25) size and lacuna (n=20) cerebral infarction groups.Results The platelet GMP-140,GMP-140 in plasma,PAdT and PAgT in large cerebral infarction group in 3 d after onset were much higher than control group (P<0.001),and the small size and lacuna groups were higher (P<0.05～0.001) than control but lower than large group (P<0.05).There was no differences between the small and lacuna groups (P>0.05).The PAdT and PAgT in 3 groups were higher (P<0.01).The platelet GMP-140 and GMP-140 in plasma in all 3 groups in 2 weeks after onset had been clearly lower but still higher than control group (P<0.05),the PAdT and PAgT were normal or even more lower.Conclusion Platelet activation was significant in different types acute cerebral infarction,the concentration of GMP-140 in plasma can reflect the degree of platelets activities more well and truly than PAdT and PAgT.

Objective To prepare cetuximab-β-glucosidase conjugates and to identify its enzymatic activity and an?tibody activity. Methods Cetuximab andβ-glucosidase were crosslinked by Sulfosuccinimidyl-4-(N-maleimidomethyl) cyclohexane-1-carboxylate (Sulfo-SMCC). Cetuximab-β-glucosidase conjugates and its enzymatic and antibody activity were examined by non-reduced SDS-PAGE, colorimetry and indirect immunofluorescence assay. Results We can see clear bands ofβ-glucosidase, cetuximab, cetuximab-β-glucosidase conjugates through electropherogram. Although the en?zymatic activity of cetuximab-β-glucosidase conjugates was lower than that ofβ-glucosidase (U/L:672.97±46.19 vs 869.50± 57.28,t=5.972,P<0.05) shown by colorimetry assay, it still maintain good enzymatic activity. Under fluorescence micro?scope, we can see the conjugates interacted with human bladder cancer EJ cells are in a red fluorescence. Conclusion Ce?tuximab,β-glucosidase were crosslinked successfully by Sulfo-SMCC without altered its enzymatic and antibody activity.

ObjectiveTo investigate the expression of CCL2 and its effects on the proliferation and adhesiveness on leukemia cells in patients with acute lymphoblastic leukemia(ALL). MethodsThe bone marrow mesenchymal cells (BMMSC) and bone marrow mononuclear cells (BMMNC) of 30 ALL patients and 30 healthy controls were studied, and CCL2 level was evaluated by ELISA. CCL2 gene mRNA level in ALL was determined by RT-PCR. The cell proliferation and adhesiveness were detected by MTT assays. The cell counts were measured by flow cytometry. ResultsThe BM plasma levels of CCL2 in patients at diagnosis were significantly higher than that in healthy controls [(780.12±129.61) pg/ml vs (120.49±25.21) pg/ml,t =4.96, P =0.00]. Supernatant levels of CCL2 in BMMSC were significantly higher than that of BMMNC [(572.38±35.39) pg/ml vs (193.85±15.45) pg/ml,t =5.37,P =0.00]in vitro.CCL2 cannot induce leukemia proliferation alone,but could induce leukemia proliferation in BMMNC and BMMSC co-culture in a dose- and time-dependent manner.CCL2 could increase the leukemia adhesive to the BMMSC compared with control (r =0.824,P =0.02).ConclusionPatients with B type ALL had higher levels of CCL2 which was secreted by BMMSC. The leukemia could induce the BMMSC to secrete CCL2. CCL2 could promote the survival and proliferation of leukemia in the presence of BMMSC and BMMNC, and enhance ALL cells adhesion toBMMSC in a dose-dependent manner.

Objective To evaluate the therapeutic effect of narrow band-ultraviolet B (NB-UVB) alone or in combination with interferon-alpha-2b (INF-alpha-2b) for mycosis fungoides (MF),and to assess the correlation between the therapeutic effect and peripheral blood regulatory T (Treg)/T helper type 17 (Th 17) cells.Methods Thirty-three patients with stage ⅠA to ⅡA MF were randomly divided into two groups:NB-UVB group (n =15) receiving NB-UVB radiation alone,combined group (n =18) treated with NB-UVB radiation and intramuscular injection of INF-alpha-2b.Ten healthy volunteers were selected as the control group.Peripheral blood samples were collected before and 9 months after the start of treatment.Flow cytometry was performed to determine the percentages of Treg cells and Th17 cells.Statistical analysis was carried out by using t test,one-way analysis of variance,and Fisher's exact test.Results The average treatment duration was 9 months among these patients.Therapeutic outcomes were significantly better in the combined group than in the NB-UVB group (P =0.023).Among the 15 patients in the NB-UVB group,6 achieved complete remission,3 partial remission,6 showed no response;of the 18 patients in the combined group,12 experienced complete remission,5 partial remission,and 1 showed no response.Before the treatment,the percentages of both Treg and Th17 cells in peripheral blood were significantly higher in the NB-UVB group and combined group than in the control group (both P ＜ 0.05),but similar between the NB-UVB group and combined group (both P ＞ 0.05).After the treatment,the percentages of both Treg and Th17 cells in the NB-UVB group and combined group significantly decreased compared with those before the treatment,but were still higher than those in the control group (both P ＜ 0.05).Additionally,the degree of decrease in the percentages of Treg and Th17 cells was significantly greater in the combined group than in the NB-UVB group (both P＜ 0.05).The seven patients with no response also showed a significant decrease in the percentage of Treg cells (P ＜ 0.05),but no obvious changes in that of Th 17 cells (P ＞ 0.05) after the treatment.Conclusions The therapeutic effect of NB-UVB radiation combined with intramuscular INF-alpha-2b is superior to that of NB-UVB radiation alone for MF,which may be associated with the degree of decrease in peripheral blood Treg and Th 17 cells.
