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 investigate the apoptotic effect induced by sulfur mustard on the lymphocytes of the rat spleen,and define the role of caspase-3 during the process.Methods Sulfur mustard was given by intraperitoneal injection in a dose of 3.5mg/kg.The animals were anesthetized and the spleens were harvested at different timepoints after intoxication.The histopathogy of spleen was studied with hematoxylin-eosin staining.Caspase-3 mRNA was detected with RT-PCR.Protein expression of caspase-3 was assayed with Western blotting,lymphocytes of rat spleen were isolated and cultured in vitro and they were challenged with sulfur mustard(100?mol/L).The effect of Ac-DEVD-CHO(a specific inhibitor of caspase-3)on sulfur mustard-induced apoptosis of the lymphocytes cultured in vitro was evaluated.Fluorescent probe labeled with Rhodamine 123 was used to study mitochondrial potential.Results The histology of rat spleen was affected after sulfur mustard intoxication,as evidenced by apoptosis of a part of lymphocytes.Protein and mRNA expressions of caspase-3 were increased significantly in the spleens of intoxicated rats as compared with that in control group.DNA ladder and 'sub-G1' peak of lymphocytes which were treated with sulfur mustard in vitro were partially improved by Ac-DEVD-CHO(the specific inhibitor of caspase-3).In addition,mitochondrial potential decreased in a time-dependent manner in the lymphocytes intoxicated by sulfur mustard in vitro compared with that in the control group.Conclusions The spleen is injured in the rat which is intoxicated by sulfur mustard.Lymphocyte apoptosis is one of the mechanisms splenic injury.Caspase-3 may be involved in the process of lymphocyte apoptosis induced by sulfur mustard.

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.

AIM: To dissociate and determine the chemical components of volatile oil from Salsola col-lina Pall.in Shandong Province METHODS: The chemical components of volatile oil were analyzed by gaschromatography-massspectraphy(GC/MS). RESULTS: Fifty-nine constituents were identified,which accounted for 87.63% of volatile oil,the major chemical componets in the volatile oil were terpenes and terpene ramifications. CONCLUSION: This method is reliable,stable and repeatable.the data can provide resources for expolitation of Salsola col-lina Pall.

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.

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.
