Objective To investigate the clinical manifestation,pathogenesis and imaging features of hemichorea associated with hyperglycemia in primary diabetes mellitus(DM).Methods Analyze the clinical manifestations,the neuroimaging features and the treatment of the three patients with hemichorea induced by hyperglycaemia in primary DM,and review the literatures about this disease.Results All of the three cases had a long history of uncontrolled diabetes,among whom,two were non-ketotic hyperglycemic patients and one was ketotic hyperglycemic patient.All of them had an acute onset hemichorea which was almost continuous during awakeness and ceased during sleep.The early CT findings in this disorder were high density in the caudate nucleus,putamen and/or globus pallidus on the side contralateral to the involved limbs,but showed decreased attenuation or completely resolved in about a month.T1-weighted MR images in all cases showed high-signal intensities without edema or mass effect in the diseased region which decreased after several months,while the T2-weighted images were more variable.Conclusion Hemichorea induced by hyperglycemia often happens in the patients with poorly controlled DM,and both of the non-ketotic hyperglycemic and the ketotic hyperglycemic state can be the cause.In the major affected region-corpora striata,CT shows hyperdense lesions,T1-weighted MR images show hyperintense lesions and T2-weighted images show variable lesions in the early time.

Objective To explore the correlation between membrane targeting of rodent Muc3 C-terminal domain and proteolytic cleavage blockage within its SEA module and N-linked oligosaccharides inhibition.Methods COS-1 cells were transfected with three different expression vectors containing rodent Muc3 C-terminal domain,namely p20,p20t and p20s/a by lipofectAMINE reagent.Inhibition of N-glycosylation of the expressed protein was performed by using tunicamycin.The transfected COS-1 cells(fixed or unfixed) were detected by immunolocalization experiments(anti-V5 and anti-Myc antibody) for the protein expression.Results In fixed COS-1 cells,the expressed product of p20 transfectant detected using both anti-Myc and anti-V5 antibodies was found to localize in perinuclear position and on the plasma membrane.While in the unfixed cells,immunostaining was only confined on cell surface using anti-V5 antibody.The expressed product of p20t transfectant was detected by anti-V5 antibody to localize only in perinuclear region,as observed in a few fixed cells.The distribution of p20s/a fluorescence resembled that of p20 transfectant.Plasma membrane targeting of the non-glycosylated products due to tunicamycin treatment still occurred in transfected COS-1 cells and resembled the glycosylated products.Conclusions The blockage of proteolytic cleavage within C-terminal domain of rodent Muc3 and its inhibition of N-linked oligosaccharides in SEA module cannot affect its membrane targeting.The only apparent requirement for membrane targeting is the transmembrane and/or cytoplasmic tail segments which exist in the C-terminal domains of rMuc3.

BACKGROUND: Joint instability may be a key agent contributing to the progress of developmental dysplasia of the hip (DDH). Neurac technique is a new modality focused on activating neuromuscular function and improving joint stability. Neurac technique may be helpful for delayed diagnosed DDH.OBJECTIVE: To observe the therapeutic efficacy of Neurac training on DDH patients.METHODS: A female patient of 23 years old with delayed diagnosed DDH received Neurac training for 14 days was retrospective analyzed.RESULTS AND CONCLUSION: The pain was relieved at 14 day after treatment. The Harris scoring showed that the hip function was improved. At 6 months follow-up, the results indicated that the remission was kept fine. Patient with delayed diagnosed DDH may get fine remission of pain and function through Neurac treatments. The effectiveness can last for a long time.

BACKGROUND: Surgery is a main method to reconstruct the stability of spine after compression fracture. But the reconstruction of spinal stability for patients undergoing conventional therapy remains unclear.OBJECTIVE: To explore whether spinal stability training is effective on improving pain and motor function of patients with vertebral osteoporotic fractures.METHODS: Patients with vertebral osteoporotic fractures were divided into two groups. The study group was treated with conventional treatments and individualized spinal stabilization training, while the control group received conventional treatments alone. All the subjects were evaluated before and after treatment by numeric pain rating scale (NPRS), 3-meter timed up and go (TUG) and Oswestry functional limitation index (OFLI). The results were compared between the two groups.RESULTS AND CONCLUSION: A total of 27 patients were included, including 16 patients in the study group and 11 in the control group. After 4-week treatment, TUG and OFLI in the study group decreased significantly compared with the control group (P < 0.05). But there was no statistical significance between the two groups in the level of NPRS and the amount of changes (P > 0.05). Symptoms and function of both groups were improved after treatments. Individualized spinal stability training is effective to restore the motor function and may be helpful for reducing pain for patients with vertebral osteoporotic fractures combined with conventional treatments.

Objective The C-terminal domain of rodent Muc3 is proteolytically cleaved.This study is to explore the relationship between N-linked oligosaccharides in SEA module and the proteolytic cleavage within C-terminal domain of rodent Muc3.Methods Truncated rodent Muc3 C-terminal domains with complete SEA module(p20SEA) were produced by site-directed mutagenesis to insert a stop code in the required place.Proteins were detected by pulse/chase and immunoprecipitation method,or SDS/PAGE and Western blot.Inhibition of glycosylation of the expressed protein was performed by using tunicamycin.Results Muc3 C-terminal domain was posttranslationally cleaved to produce a V5-tagged 30 000 extracellular glycopeptide and a Myc-tagged 49 000 membrane-associated glycopeptide.Treatment with tunicamycin to transfected COS-1 cells led to the abundant production of 60 000 uncleaved and whole-length Muc3 C-terminal domain,the 30 000 N-terminal fragment shifted to 22 000 and 49 000 C-terminal fragment shifted to 41 000 after deglycosylation.The truncated Muc3 C-terminal domain containing complete SEA module but without the following residues led to production of 36 000 uncleaved and whole-length protein,and 30 000 cleaved product shifted to 22 000 after deglycosylation.Conclusion Proteolytic cleavage in both complete rodent C-terminal domain and complete SEA module without the following residues were partially inhibited by tunicamycin.

Objective To observe the effect of BSD 2000 deep thermotherapy plus chemotherapy in treatment of malignant seroperitoneum of advanced epithelial ovarian cancer patients with drug resistance.Methods 36 advanced epithelial ovarian cancer patients with malignant seroperitoneum for drug resistance were randomly divided into two groups,trial group (18 cases) and control group (18 cases).Cases in trial group were treated with BSD 2000 deep thermotherapy plus GT regimen (gemcitabine 1 000 mg/m2 iv d1,d8,taxinol 80 mg/m2 ip d1,d8.28 days for a cycle),while control group with GT regimen alone.Effect,survival time (median) toxicity and Karnofsky score were evaluated after 2 cycles.Results Response rate (RR) was strongly higher in trial group compared with control group [55.6 ％ (10/18) vs 22.2 ％ (4/18),P ＜ 0.05],the same to disease control rate (DCR),but there was not significant difference between two groups (P ＞ 0.05).The improvement rate of Karnofsky score in trial group was higher than that in control group,which had no significance (P ＞ 0.05).The toxicity were similar in both groups,which had no stage 3 to 4 side-effect.The differences of survival time (median) and survival rate had no statistical significance between two groups (P ＞ 0.05).Conclusion It is useful to eliminate seroperitoneum,improve quality of life and decrease the toxicity for the regimen of BSD 2000 deep thermotherapy plus chemotherapy in treatment of malignant seroperitoneum of advanced epithelial ovarian cancer patients with drug resistance.

Objective To investigate the role of Ki-67,c-myc,p53 in human in esophageal cancer.Methods 25 specimens of human esophageal cancer as observe group and 25 adjacent normal specimens as control group were selected.Expressions of Ki-67,c-myc,p53 protein were detected by immunohistochemical staining.Results Protein expressions levels of Ki-67,c-myc and p53 in human esophageal cancer were significantly higher than those in control group 5.0,2.0,3.0 vs 1.0,0.5,0.3,respectively (all P ＜ 0.05).The expression level of Ki-67 protein in high differentiation group were significantly lower than that of moderate and low differentiation group (3.0 vs 6.0,P ＜ 0.05).In human esophageal cancer specimens,the expression level of Ki-67 protein was positively correlated with that of c-myc (P ＜ 0.05).Conclusion The expressions of Ki-67,c-myc and p53 are higher in esophageal cancer,which are increased with the higher differentiation.Ki-67,c-myc and p53 proteins may be taken as potential markers in human esophageal cancer.
