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.

To cultivate talent of higher education is the education's purpose and foundation of development. Studying ethnomedicine's higher education and sorting out the skeleton could help to enrich the theory of the development of traditional ethnomedicine and offer thought and reference for educational career.

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.

Objective: To study the microstructure of e-polytetra fluoroethylene (e-PTFE) membrane and chitin membrane and to observe the growth of osteoblasts on the membrane. Methods: Light microscope and scanning electronic microscope were used to study the microstructure of e-PTFE membrane and chitin membrane. Cell culture methods and cell counting were used to observe the growth of osteoblasts on the two kinds of membrane. Results: The chitin membrane showed a compact structure without any pore in it. There were many shallow dents with the diameter of 5-8 ?m on it's surface. However, in e-PTFE membrane many tiny lined cracks (1-5 ?m in width and 5-15 ?m in length) in elliptic structure were observed. The adhesion and proliferation of osteoblasts on the two kinds of membranes were both well. ALP measurement showed that there were no significant difference between each of the two membrane groups and the control. Conclusions: Both membranes have no negative effects on the growth of osteoblasts. Both membranes are biocompatibile and their microstructure is appropriate for guided bone regeneration materials.

Objective To explore the typing,precaution and treatment of the bone cement leakage caused by percutaneous vertebroplasty(PVP).Methods PVP was performed in 38 cases(11 men and 27 women) with vertebral angioma and vertebral body compression fracture with osteoporosis chosen from November 2002.Results All the patients were followed up for 8 to 16 months and the effects were evaluated by the standards carried out by World Health Organization(WHO).The rate of complete response(CR) plus partial response(PR) was 100 percent.The patients with bone cement leakage by PVP were divided into 3 groups which underwent different remedial methods respectively.Conclusion The bone cement leakage could be prevented through the preoperative preparation,choosing the anaesthesia and scouting the whole operation.The patients with TypeⅠ,Ⅱ and Ⅲ_a needn't treatment,but those with type Ⅲ_b must accept open-operation.Vertebral eggshell technology with open vertebroplasty was effective on the treatment of the bone cement leakage with type Ⅲ_b caused by PVP.

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.
