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.

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 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.

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 response rate and survival rates of refractory or relapsed Hodgkin lymphoma (HL) and grey zone lymphoma patients treated with autologous peripheral blood stem cell transplantation (APBSCT).Methods From January 2004 to August 2012,30 HL and grey zone lymphoma patients were retrospectively analyzed.Statistical analysis was done to explore the long term outcome and prognostic factors of patients treated with APBSCT.Among all patients,the median age at transplantion was 30 (13-55) years old.Patients were major with nodular sclerosis HL and in stage Ⅲ/Ⅳ.Results Every patient had a successful collection.The median MNC cell dose infused was 6.8×108/kg [range (1.0-13.8)×108/kg] and median CD34+ cell dose infused was 6.3×106/kg [range (0.6-20.6)×106/kg].Median time to neutrophil engraftment was 9 days (range 8-12 days).28 patients were evaluable after transplantation with a median follow-up of 18.5 months (range 2.5-95.0 months).The overall response rate was 89.3 ％ [CR 64.3 ％ (18/28),PR 25.0 ％ (7/28)].The overall survival (OS) rate and progression free survival (PFS) rate at 5 year would be 78 ％ and 58 ％ for all patients.3 in 7 patients with no remission after salvage chemotherapy with rituximab plus chemotherapy before APBSCT got CR and 2 got PR.Univariate analysis showed that disease status and the number of replacement types of chemotherapy prior to transplantation affected OS,the history of radiotherapy prior to transplantation affected PFS.Conclusion APBSCT can increase CR rate,prolong survival time in patients with refractory or relapsed HL and grey zone lymphoma.Rituximab plus chemotherapy as a salvage therapy could raise CR rate before APBSCT.Chemosensitivity before transplantation affect outcome with APBSCT.Changing many types of chemotherapy is adverse for APBSCT.Salvage radiotherapy before APBSCT is not recommended.
