Objective A series of 5 patients with central pontine myelinolysis (CPM) confirmed either by cranial MRI,CT image (4 cases) or by autopsy pathological analysis (1 case) was reported. The pathophysiological mechanism,the early diagnosis and the role in prevention were discussed. Methods The creteria obtained from clinical features, cranial MRI and CT imagine as well as autopsy pathological changes were thoroughly analyzed. Results ① All 5 case of CPM were occurring in patients who had already had somatic disease and serious systemic functional failure, especially in those who had had seriously water and ion disturbances, such as hyponatremia. ② In 4 of the 5 patients, psychiatric manifestation tended to show the earliest clinical features. ③ The pseudobulbaral paralysis appeared in 4 patients. ④ Cranial MRI and CT served as the most reliable techniques for diagnosing CPM cases when patients are still alive. ⑤ A variety of paralysis were found in all of the 5 CPM patients. ⑥Pathological analysis demonstrated that there is a symmetric unspecific myelinolysis in areas of basal pontine, caudal middle brain and the superior medulla (1 patient). Conclusion ① The occurrence of hyponatrimia and its too fast correction may be associated with the onset of CPM. ② CPM, a self-restrained disease can be cured from dangerous complications, such as pneumonia, respiratory failure and malnutrition when suitably treated.

ObjectiveTo study the relationship between function of cardiac autonomic nervous system and 24-hourambulatory blood pressure in diabetes mellitus with normal blood pressure in the casual assay.Methods71 DMpatients with normal blood pressure in casual assay were measured with cardiac power spectral analysis and 24hAMBPassessment.ResultsThere was no difference in 24hAMBP between DM patients without AND and normal subjects.24-hour ambulatory systolic pressure values and the prevalence of blood pressure burden in DM patients with mild AND were significantly higher than that in the control group and the percentage of day-night change in AMBP weresignificantly lower than that in the control group.In DM patients with severe AND, 24-hour ambulatory systolicpressure values and the prevalence of 24hAMBP burden were higher and the percentage of day-night change was lowerthan that in DM patients with mild AND, however, there was no significant difference between them.Conclusion Blood pressure was in severe disorder as soon as cardiac AND appear in DM patients with normal casual blood pressure.Abnormality of ANSF and blood pressure in DM patients contributed to the onset and development of cardiovascularevents.They are very important for investigating cardiac ANSF in DM patients and early intervening and treating DMpatients with AND.

Objective To investigate the protective effect of ginsenoside Rb1 and Re on injury of the neonate rat cardiomyocyte induced by aconitine alkaloids.Methods The influence of aconitine and ginsenoside Rb1,Re together in neonate rat cardiomyocyte was observed respectively.The influence of these components in neonate rat cardiomyocyte was examined by myocard zymogram.The expression of Ca2+ channel gene Cav1.2 mRNA of neonate rat cardiomyocyte after treatment was observed by RT-PCR.Results The ginsenoside Rb1 and Re were able to decrease the release of AST and LDH,reverse Cav1.2 mRNA abundance induced by aconitine.Conclusion The ginsenoside Rb1 and Re which together with aconitine can alleviate the side effects and boost up the therapeutic effects of aconitine.The action mechanism may be relation with that the ginsenoside Rb1 and Re can decrease injuries of the neonate rat cardiomyocytes and abundant expression of Cav1.2 mRNA induced by aconitine.

Target of the treatment for advanced pancreatic carcinoma is always palliative without prolongation of survival time almost, therefore the aims of treatment should be concentrated on improving the quality of life and alleviateing the disease-related symptoms. We do not call for the treatment and medicines that can incur obvious adverse reaction with limited effectiveness. Interventional therapy provides superexcellent short term efficacy with alleviating the disease-related symptoms significantly, and without severe side effects and thus coincides to the principle of the treatment for advanced pancreatic carcinoma. The surpassing advantages provide popular recommendation for this very kind of therapy in the recent years.

Polymerase chain reaction was employed to amplify the HBV X gene from plasmid pCP10, and the product was cloned into pVR1012, then transfected HepG2 cells and cotransfected HepG2 cells with reporter plasmid pSV lacZ HBx protein produced by HepG2 cells was measured by ELISA method The activity of ? galactosidase was measured by a kit, which reflected the transactivating function of HBx protein The results showed that HepG2 cells transfected by pVR1012 X could express HBx protein The expression of ? galactosidase in HepG2 cells transfected by the pVR1012 X was 3 2 fold higher as that of control plasmid It is suggested that the recombinant plasmid pVR1012 X can be expressed in mammalian cell line, and has transactivating effect on SV40 early promoter

Objective To investigate the correlation between level of Titin antibodies (Titin-Ab) and patient's condition and different thymic pathological patterns in patients with myasthenia gravis (MG), and to assess its value in the diagnosis and prognosis of MG.Methods The levels of Titin-Ab in serum from 52 patients with MG (MG group), 18 cases with other neurologic diseases (NMG group) and 50 normal controls (NC group) were detected using enzyme-linked immunosorbentassay (ELISA). 10 cases with MG who received operation on thymus were tested again after therapy.Results The positive rate of Titin-Ab in MG group was 36.5%,but not present in MNG and NC groups.The MG group!was significantly higher than those in NMG group and NC group (all P

Objective To evaluate the therapeutic efficacy of microendoscopic tubular retractor system (METRx) with a postmedial approach in the treatment of lumbar disc herniation. Methods A total of 290 patients with lumbar disc herniation were treated with METRx. The duration of follow-up ranged from 3 months to 33 months. Results According to the Nakai scale, 81% (235 cases) of the patients were evaluated as excellent, 13.4% (39 cases) as good, 4.8% (14cases) as fair and 0.7% (2 cases) as poor. Postoperative infection in intervertebral space was found in 2 cases. Conclusions METRx has a satisfactory short-term therapeutic efficacy in the treatment of lumbar disc herniation.

Objective To compare the curative effect between arthroscopic and open retrograde intramedullary interlocking nails in the treatment of femoral supracondylar fracture. Methods A total of 46 patients with femoral supracondylar fracture underwent the treatment by either arthroscopic (19 patients, Group A) or open (27 patients, Group B) retrograde intramedullary interlocking nails. Results The operation time, surgical blood loss and bone union time in the Group A were less than those in the Group B ( t =-4 193, -21 517 and -4 055, respectively; P =0 000). Follow-up for (10 3?3 6) months in the 46 patients revealed the results of therapy were, according to the Kolmert criteria, excellent in 15, good in 3, fair in 1 in the Group A while excellent in 7, good in 14, fair in 4 and poor in 2 in the Group B, without statistically significances between the two groups in the “good” or “excellent” rates (94 7% vs. 77 8%; ? 2 =1 345, P =0 246). Conclusions Use of arthroscopic retrograde intramedullary interlocking nails has advantages of shorter operating time, less blood loss and quicker bone union, benefiting the recovery of knee joint functions.
