Objective To explore the correlation factors of hospital stay and hospitalization costs among patients with acute ischemia stroke (AIS). Methods The clinical data of the patients with first diagnosis of AIS at Peking University Third Hospital in China from January 1 , 2012 to December 31 , 2012 were retrospectively analyzed to investigate the correlation factors of hospital stay and hospitalization costs using univariate analysis and multiple regression analysis. Results The study involved 496 patients, with a mean age of 63.38 years (range:26~88 years). Multivariate regression analysis showed the significant impact factors for LOS were age, pneumonia, the total score on NIHSS, medication for secondary prevention and stroke subtype. The significant impact factors for cost of hospital stay were payment method, stroke subtype, age, the total score on NIHSS and medication for secondary prevention. Conclusions Age, pneumonia, the total score on NIHSS, stroke treatment and its subtypes are the significant impact factors affecting hospital stay. Payment method, stroke subtype, age, the total score on NIHSS and medication for secondary prevention are the significant impact factors affecting costs of hospitalization.

0.05)between the recurrent rate[2.2%(10/463)]of the CR patients with lung metastasis and the progression rate of the 152 patients.Conclusions After normalization of ?-hCG titer,patients whose lung tumors remained unchanged even after several additional courses of chemotherapy should be considered as CR patients.Follow-ups should be strictly carried out on these patients,especially at around 6 months after the completion of treatment,and particularly for high-risk and drug-resistant choriocarcinoma patients.

Objective To compare the prophylactic effect of laminar closure between titanium miniplate and anchor fixation in open-door cervical laminoplasty.Methods Between January 2010 and December 2010,63 patients with cervical spondylotic myelopathy were treated by open-door laminoplasty.Of them,30 patients underwent laminoplasty by titanium miniplate fixation and 33 by anchor fixation.During follow-up,multi-detector CT was performed preoperatively,at 1 week and 6 months after surgery.At each level,the anteroposterior diameter (APD) of the spinal canal and opening angle (OA) were measured.And the spinal canal expansion rate are calculated.MRI was performed preoperatively and 1 year after surgery to evaluate the severity of cord compression.Results All incisions healed by first intention.The incidence of postoperative axial symptoms in miniplate fixation group and anchor fixation group were 33.3％ (10/30) and 39.4％ (13/33),respectively.The OA,APD,and the spinal canal expansion rate of patients in both groups improved significant postoperatively,but differing from miniplate fixation group.The OA,the APD and the spinal canal expansion rate in anchor fixation group after 6 months were reduced than one week after surgery,and the difference between the groups was statistically significant.Lamina close in two groups was not found.CT images at 6 months showed complete fusion of the hinge area by mature bone or callus in two groups,by cervical sagittal MRI assessment.The severity of spinal cord compression was improved after 1 year.Preoperative and 1 year after the surgery,the severity of spinal cord compression between the two groups showed no significant difference.The severity of spinal cord compression after 1 year in both groups were no more than three grade.Conclusion Open-door cervical laminoplasty by anchor fixation or titanium miniplate can effectively prevent the occurrence of postoperative lamina closure,which can help patients to do functional exercises early,but improvement of spinal cord compression has no significant difference between both of them.However,titanium miniplate fixation for maintenance of the expansive spinal canal is better.

OBJECTIVETo explore the effect of Danshensu on the lipid metabolism of hyperlipidemic rats.

METHODSixty clean male SD rats were selected. Twelve of them were selected in the basic control group and fed with common foods, and the remaining rats were fed with the high-fat feeds. After the successful modeling, they were randomly divided into the high-fat control group and low dose (10 mg x kg(-1) x d(-1)), medium dose (20 mg x kg(-1) x d(-1)) and high dose (40 mg x kg(-1) x d(-1)) Danshensu (dissolved in saline) groups. Both of the two groups were abdominally injected with the same volume of normal saline once a day for consecutively 30 days. The serum TG, TC, HDL-C and liver ACC1, FAS, HMGR, CPT-I mRNA expressions were detected.

RESULT AND CONCLUSIONDanshensu could inhibit the LDL-C level, timely clear redundant cholesterol and effectively regulate the lipid metablism of hyperlipidemic rats by reducing the TC content, decrease the fatty acid by reducing the FAS mRNA expression, and reduce the synthesis levels of endogenous cholesterol by inhibit the HMGR mRNA expression.

Objective To study the effect of heat stress on the permeability,cytoskeleton and cell cycle of human skeletal muscle cell (HSKMC).Methods The HSKMC membrane permeability was detected by calcium ion inflow with flow cytometer,the cytoskeleton was stained by CBB 250,and the cell cycle was determined by flow cytometer.Results After 1 h of heat stress on human HSKMC cells under different temperature gradient,the median level of calcium ion was 91.63 in 43 ℃ heat stress group compared with 22.98 in 37 ℃ control group.As temperature increased,thicker and shorter cytoskeleton and stress fiber were shown under the high power lens of microscope.The DNA expression of skeleton cells at G0/G1 stage was 44.13-62.98 in groups under heat stress.Compared with normal control group,DNA expression was much higher in heat stress group,when HSKMC was cultured under 37 ℃ temperature for another 18 h,it kept decreasing DNA expression to a similar level as control group.Conclusions Heat stress can cause calcium iron inflow resulting in intracellular calcium overload,and affect the cytoskeleton leading to loss of normal web ordered arrangement and increased gap in HSKMC cells,which give rise to blocking cell cycle into G0/G1 stage.

Objective To evaluate the protective effect of aminophylline on myocardium in the patients undergoing prothetic valve replacement operation of heart.Mothods Thirty patients undergoing prothetic valve replacement operation of heart were randomized to be treated either with aminophylline(n=15)or without aminophylline treatment(n=15). Aminophylline(5mg/kg)was injected intravenously at 15 minutes after induction of anesthesia.Cardiac troponin I(cTnI), cyclic adenosine monophosphate(cAMP),myeloperoxidase(MPO),ratio of aortic blood neutrophil count to coronary vein sinus blood neutrophil count,hemodynamics,time of aortic cress-clamping and other clinical data were recorded during the operation.Results There were no differences between the two groups in the major perioperative variables.Plasm cTnI concentration in both groups increased after off-clamping than that before CPB,however,it was lower in aminophylline group than that in control group.Concentration of cAMP in both groups after off-clamping was lower than that before CPB, however cAMP concentration in aminophylline group after off-clamping was higher than that in control group.Myocardial MPO activity and neutrophil count ratio after aortic off-clamping in aminophylline group was significantly lower than that in control group.Conclusion These results suggest that aminophylline is helpful to unprotection of myocardial and decreases the sequestration of neutrophil in myocardium.The mechanism of the protection may be related to the cAMP increased in myocardium.

Objective To evaluate the susceptibility of itraconazole-resistant Aspergillus fumigatus isolates to four other antifungal drugs.Methods Six strains of Aspergillus fumigatus were serially isolated from a patient with lung aspergilloma,who was resistant to itraconazole therapy.Clinical Laboratory Stan- dard Institute broth microdilution method M38-A and E-test were applied to test the susceptibility of A.fumi- gatus strains to amphotericin B,itraconazole,voriconazole,caspofungin and micafungin.Results With M38-A method,the minimal inhibitory concentration(MIC)of itraconazole was 0.5?g/mL for 2 strains and more than 16?g/mL for the other 4 strains;the MICs of amphotericin B and voriconazole were 1?g/mL and 0.25-1?g/mL respectively for all the 6 strains;and the minimal effective concentration(MEC)of caspofungin and micafungin were no more than 0.03?g/mL for all the 6 strains.Moreover,E-test results also revealed that caspofungin and voriconazole had a good antifungal activity against all the strains,including the 4 itraconazole-resistant ones.Conclusion The itraconazole-resistant A.fumigatus strains isolated from a patient with lung aspergilloma are susceptible to amphotericin B,voriconazole,caspofungin,and micafungin.
