Clinical data of 595 patients of stroke admitted to the First Affiliated Hospital of Dalian Medical University, Dalian, Liaoning were analyzed retrospectively, 310 (52. 1% ) of them with strokeassociated pneumonia (SAP). Early-onset pneumonia occurred in 225 patients (72.6%), and late-onset pneumonia in 85 (27.4%). Patients with length of hospital-stay equal to or more than two weeks accounted for (113 cases) 50. 3% of those with early-onset pneumonia, whereas patients with length of hospital-stay less than one week (60 cases) accounted for 70. 6% of those with late-onset pneumonia. Age above 65 years ( OR = 1. 037 ), diabetes ( OR = 1. 724), Glasgow coma scores equal to or less than eight ( OR = 0. 098 ),nasal feeding ( OR = 6. 640 ), administration of gastric mucosal protective drugs ( OR = 3. 581 ) and antibiotic prophylaxis ( OR = 2. 433) all were risk factors for SAP.

For the purpose of detecting the polymorphism of the human eighth complement component(C8A),an allele specific amplification method were established for detecting two alleles of C8A based on a nucleotide exchange of the C8? cDNA sequence.100 DNA blood samples from unrelated individuals of Han population in Chengdu were typed by this method.The result of comparison with the data of protein typing of the same samples using SDS PAGE method proved that the described method is efficient,correct and reliable for C8A genotypes.This methtod is valuable for further application in population genetic study and forensic science practice.

Objective: To investigate the immunosuppressive effect of sinomenine (SIN) on xenogenic skin transplantation in mice.Methods: BALB/c→C57BL/6 tergal skin transplantation model was established by an operation, and then the mice were divided into 5 groups at random, namely sham group, model group, SIN group (30 mg·kg-1), ciclosporin A group (CsA) (10 mg·kg-1) and combination of SIN and CsA group (SIN 30 mg·kg-1 and CsA 5 mg·kg-1) (n=10).All the mice were intraperitoneally administered once a day for ten days.The survival days of skin graft were recorded, and the IL-2 levels in plasma were determined by ELISA respectively on the 4th and 8th day after the operation.Results: The mean survival days of skin graft in the groups treated with different drugs were significantly prolonged when compared with that in the model group (P<0.01).The combination of SIN and CsA administration showed longer mean survival days than SIN or CsA (P<0.05 or P<0.01).The IL-2 levels in plasma in the groups treated with different drugs were significantly reduced than those in the model group on the 4th and 8th day after the operation (P<0.01).Conclusion: SIN may have a good immunosuppressive effect in the mice with xenogenic skin transplantation, and the combination of SIN and CsA shows a synergistic effect.

Objective: To explore the high dose atorvastatin reducing contrast induced nephropathy (CIN) rate in patiens with emergent percutaneous coronary intervention (PCI) via improveing heat shock protein-90 (HSP90) expression with its possible mechanism. Methods: A total of 158 STEMI patients with emergent PCI in our hospital were studied. The patients were randomly divided into 2 groups: High dose atorvastatin group, the patients received pre-operative atorvastatin 40 mg,n=80 and Control group, the patients received pre-operative placebo,n=78. The serum creatinin (Scr), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), superoxide dismutase (SOD), malondialdehyde (MDA), nitrogen monoxide (NO), HSP90 mRNA expression and protein concentration and urine α1-microglobulin were examined in all patients and the incidence rates of CIN were compared between 2 groups. Results: Compared with Control group, High dose atorvastatin group had drcreased Scr (68.92 ± 8.80) μmol/L vs (77.25 ± 13.36) μmol/L, MDA (3.88 ± 0.53) nmol/L vs (4.08 ± 0.52) nmol/L and urine α1-micrglobulin (1.38 ± 0.36) mg/dl vs (1.89 ± 1.13 ) mg/dl; increased Ccr (89.71 ± 9.85) ml/min vs (77.28 ± 13.78) ml/ min, SOD (129.52 ± 30.63) U/ml vs (117.66 ± 27.98) U/ml, NO (66.23 ± 29.26) μmol?gprot vs (55.12±27.43) μmol?gprot, allP<0.05. Compared with Control group, High dose atorvastatin group presented higher post-operative HSP90 mRNA expression (0.466 ± 0.158) vs (0.224 ± 0.278 ) and protein concentration (1259.83 ± 121.17) pg/ml vs (1195.0 ± 127.65) pg/ml, allP<0.05. The incidence rate of CIN was lower in High dose atorvastatin group (2.5%) than Control group (10.3%),P<0.05. Conclusion: A high dose atorvastatin administration before emergent PCI may decrease CIN occurrence rate. Atorvastatin may promote HSP90 expression, increase NO produciton, then improve the vascular endothelial function and anti-oxidative ability to protect the renal function in STEMI patients.
