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.

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 research the simultaneous purification process of shikimic acid and total flavonoids from pine needles of Cedrus deodara (Roxb.) G. Don. Methods: Taking the purity of shikimic acid and total flavonoids as the evaluation indicator, the purification effect of six macroporous resins were evaluated. Orthogonal design L9(34) and single factor experiments were employed to optimize the purification conditions by comprehensive scoring. The purification capacity of the best resin was investigated by the sample mass concentration, the volume flow of the sample, the ratio of the resin to the drug, the amount of water for washing, the concentration of ethanol, and the elution of ethanol. Results: XAD 7HP macrophous resin offered better purification effect of shikimic acid and total flavonoids from pine needles of C. deodara than other macrophous resins. The optimum purification condition was confirmed as follows: The concentration of shikimic acid in the sample was 11.59 mg/mL, and total flavonoids concentration was 6.9 mg/mL; The flow rate was 8 BV/h, and the sample volume was 2.0 mL/g; The shikimic acid was eluted with loading capacity and 4 BV of water; The total flavonoids was eluted with 4 BV of 70% ethanol successively. The purity of shikimic acid can be increased from 19.25% to 28.98%, and the purity of total flavonoids can be increased from 11.92% to 54.45%. Conclusion: The optimized purification process is stable, feasible and suitable for pilot enrichment of shikimic acid and total flavonoids from pine needles of C. deodara.

Objective: To study the chemical constituents of flavonoids in the pine needles of Cedrus deodara. Methods: Flavonoids were isolated and purified from ethyl acetate extract of the pine needles by chromatography on silica gel and Sephadex LH-20. Their structures were identified on the basis of spectroscopic analysis and chemical evidence. Results: Five flavonoids were isolated and identified as 3′,5′-dimethoxymyricetin-3-O-(6″-O-acetyl)- α-D-glucopyranoside (1), myricetin (2), 2R,3R-dihydromyricetin (3), quercetin (4), and 2R,3R-dihydroquercetin (5). Conclusion: Compound 1 is a new compound named as cedrusone A. Compounds 2-5 are isolated from the pine needles in the plants of Cedrus Trew for the first time.

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.
