Objective: To observe the therapeutic effect of nicorandil on microvascular angina pectoris (MAP). Methods: A total of 60 MAP patients were randomly divided into nicorandil group (n=30) and routine treatment group (n=30), and they were treated for 12 weeks. Onset times and duration of angina pectoris, changes of related parameters of ECG treadmill exercise test before and after treatment, and total effective rate were compared between two groups. Results: Compared with before treatment, there were significant reductions in onset times and duration of angina pectoris and maximum depression extent of ST segment (P<0.05 or <0.01) and significant increase in total exercise time (P<0.01) after treatment in both groups; compared with routine treatment group, there were significant reductions in onset times of angina pectoris [(10.3±1.6) times/week vs. (9.6±1.7) times/week] and maximum depression of ST segment [(0.8±0.3)mm vs. (0.6±0.2)mm], and significant increase in total exercise time [(7.8±1.4) min vs. (9.4±1.6) min] and total effective rate (73.3% vs. 93.3%) in nicorandil group, P<0.05 or <0.01. Conclusion: Nicorandil possesses significant therapeutic effect on microvascular angina pectoris, and it is worth further study.

Objective To investigate the causes and prevention on complications of percutaneous vertebroplasty(PVP). Methods Forty three cases with 64 vertebrae were performed PVP from May 2001 to October 2003. The incidence of complication was 13 cases (30.2%). Leakage of polymethylmethacry (PMMA) without symptoms occurred in 4 cases. Leakage with pain occurred in 3 cases. No leakage but with pain occurred in 4 cases after the procedure. Fracture of adjacent vertebrae occurred in 2 cases. All cases were followed up from 3 to 29 months (in average of 13.2 months). Results There wasn′t severe complications in 7 leakage cases. The pain in 7 cases was relieved and disappeared at 2-7 days after the procedure. The symptoms of pain in 2 cases of adjacent vertebrae fracture were relieved. Conclusion If sufficient preventive measures are applied before or during the procedure of PVP,the complications may be reduced effectively.

Objective To induce experimental allergic encephalomyelitis (EAE) in female C57BL/6 mice with the extracellular domain of myelin oligedendroglia glycoprotein(MOG~(Igd)). Percentages of CD4~+ CD25~+ T cell (Tr) were tested , and also normalized expressions of Foxp3. Methods Molecular cloning technology was used to produce MOG~(Igd) fusion protein. The MOG~(Igd)-TrxA fusion protein and TrxA protein were purified by metal chelate affinity chromatography (MCAC). Mice were injected s. c. in the flank with 300 μg MOG~(Igd) in complete Frcund's adjuvant (CFA) supplemented with 4 μg/μl Mycobacterium tuberculosis. H37Rv. Mice received 0.4 ml emulsion of spinal cord homogenate of guinea pigs (GPSCH) in positive control group, and the same volume emulsiom of TrxA in negative control group, while mice served as normal control received only saline/adjuvant. Mice were monitored two times a day for continuously 30 days by double bind. Clinical scores and histopathology were evaluated. Then, mice were sacrificed. The spinal cord and brain were removed and fixed in buffered formalin. Horizontal sections taken from the central nervous system(CNS) were stained with haematoxylin and eosin (HE), and Kluver-Barrera staining. Also, immunohistochemistry was performed. Percentages of CD4~+ CD25~+ T cells were tested through flow cytometric analysis, and real-time PCR was performed to test normalized expressions of Foxp3 mRNA. Then, correlations between the two were performanced. Results Mice in both MOG group and GPSCH group shew chronic non-remitting course. The onset of disease, time when the most severe clinical symptoms happened and the clinical score between the two groups shew no significant differnces (P>0.05). However, neither in TrxA treated group nor in normal control group did animals exhibit clinical signs of EAE. Histologic sections of the brain and spinal cord taken from affected animals shew perivascular infiltration of mononuclear cells, gliosis, and multifocal demyelination. Lesions scattered throughout the CNS including brainstem, spinal cord, cerebellum, and penventricular white matter. There were significant differences between MOG group and TrxA group in the level of lesion-ceutric AQP-4 expression showing up by immunohistochemistry (P<0.05). Percentages of CD4~+ CD25~+ T cells in MOG group and GPSCH group were (4.71±1.61) % and (1.44±0.65) %, respectively, both of which were significantly lower than those in the normal control group or TrxA treated group (P<0.01). And the difference between MOG group and GPSCH group also reached statistics meaning (P<0.01). Normalized expression of Foxp3 mRNA in MOG group was 2.26± 1.97, and was not significantly higher than the 1.44±1.20 level in GPSCH group (P>0.05). However, they beth were statistically lower than that in the negative control group, namely 8.58±3.34 (P<0.01). Percentages of CD4~+ CD25~+ T cells was statistically correlated with expressions of Foxp3 mRNA (P< 0.05). Conclusion EAE induced in C57BL/6 mice with MOG~(Igd) is reproduceable. It shares the similar clinial signs and pathologic features with human multiple sclerosis(MS). Thus, we find a good way to further study the immune mechanisms of MS and also to search for the effective treatments.

Objective To analyze and discuss the effect of heat preservation on the recovery time of BIS and the concentration of propofol in the recovery period of the elderly patients with general anesthesia in order to provide guidance for clinical treatment.Methods78 elderly patients with general anesthesia were selected as the subjects, and the patients were divided into the control group and the study group with 39 cases in each group.The patients were divided into the control group and the study group.Control group, only to be liquid input and covered by drapes, research group take liquid input and peritoneal flushing fluid heating and heating blanket coverage of insulation measures, were recorded and compared between the two groups from anesthesia began to operation to complete the different time points of esophageal temperature and MAP, and to observe the recovery time of patients and effect compartment concentration differences.ResultsTwo groups at T0, T1 esophageal temperature no significant difference, study group t2-t6 esophageal temperatures were significantly higher than those of the control group (P<0.05), maps of the other two groups at different time points had no significant difference;when two groups of patients with propofol withdrawal BIS values had no significant difference (P<0.05), and in the time of discontinuation BIS is more than or equal to 80 recovery time and effect compartment concentration have significant difference (P<0.05).ConclusionThe surgical treatment of elderly patients with general anesthesia can help maintain the body temperature, shorten the recovery time of BIS and reduce the concentration of propofol in the recovery period.

Objective To investigate the effect of cytokines on pancreatic function in patients after acute pancreatitis(AP) and its mechanisms. Methods Fifty-nine patients (mild in 25 and severe in 34) after AP and 20 healthy controls were enrolled in the study. Serum levels of cytokines including hepatocyte growth factor (HGF), epidermal growth factor(EGF), basic fibroblast growth factor (bFGF), regeneration protein(Reg)-1 and Reg-4 were determined using enzyme-linked immunosorbent assay (ELISA). Fasting blood-glucose, insulin, C-peptide and fecal elastase 1 (FE1) were detected for evluation of endocrine and exocrine pancreatic function. The association of pancreatic function with clinical parameters and serum cytokines was analyzed. Results The expression of FE1 was lower in patients [(205.9±18.3) μg/g] after AP in comparison with the controls [(333.9±19.7) μg/g, P<0. 01], but levels of fasting blood-glucose, C-peptide and insulin were higher in patients group (P<0.01). Serum level of HGF was higher in patients with insufficient pancreatic exoerine [(983.76±372.65) pg/ml] than those with normal exocrine function [(263.44±110. 35) pg/ml]. Meanwhile,EGF level was higher in patients with DM after AP [(704.41±190. 37) pg/ml] than those without DM [(360. 03±48.39) pg/mh P<0.05]. There was a negatively correlation between FE1 and HGF (P ＜0. 01). The abnormal fasting blood glucose was correlated with CT grading (P<0. 05).Conclusions The patients after AP develope insufficient exocrine and endocrine function. Serum EGF and HGF may be associated with restoration of pancreatic endocrine and exocrine function.
