Objective To explore the change and its significance of blood concentrations of high sensitive C-reactive protein(hs-CRP) and D-Dimer in patients with acute cerebral infarction caused by internal carotid artery.Methods The blood levels of D-Dimer and hs-CRP in 69 patients with acute cerebral infarction were measured,and compared with the normal controls.The relationships between the levels of hs-CRP and D-Dimer and NIHSS or the areas of infarction were analyzed.Results Compared with those in normal control group,the blood levels of D-Dimer and hs-CRP in patients with acute cerebral infarction increased significantly(all P

To evaluate the efficacy and safety of compound Decumbent Corydalis Rhizome (DCR) in treating patients with knee osteoarthritis (OA). Totally 79 patients with knee osteoarthritis were selected from out-patient and inpatient departments of West China Hospital and randomly divided into the test group and the control group. The test group (n = 41) was given Compound DCR with the dosage of 1.8 g · d(-1), while the control group (n = 38) was administered with diclofenac sodium with the dosage of 75 mg · d(-1). After 12 weeks of treatment, the total efficacy rates based on patients/physicians evaluation for experimental and control groups were 68.29%, 63.41% and 71.05%, 63.16%, respectively, without significant difference between the two groups. Both of the two groups showed significant improvements in the main efficacy indexes (pain on walking 20 m) and minor indexes (tenderness on palpation, Western Ontario and McMaster Universities OA index (WOMAC) and Short-Form Health Survey (SF-36 ), but without significant difference in efficacy between them. The incidence of related adverse events was 24.39% in the test group and 47.37% in the control group, respectively, with significant differences between the two groups (P < 0.05). In the controlled study, compound DCR is as efficient as diclofenac sodium but more tolerable, with a good clinical application prospect.

Background N-ethyl-N-nitrosourea (ENU)-induced mouse mutagenesis is a powerful approach for the study of gene function and the generation of human disease models.Objective This study was to create the corneal morphologic change and map the mutant gene of a kind of corneal opacity in ENU mutagenesis in mouse.Methods ENU was intraperitoneally injected in forty C57BL/ 6J (B6) male mice aged 8-10 weeks old.The male mice were mated with the same strain female mice.Their progenies were screened for visible eye mutation,and the mutant mice were mated with the same strain mice to confirm the heredity of mutation phenotypes.Hematoxylin & eosin staining was used to examine the histopathological change of cornea in one mouse with ENU-induced corneal opacity.To map the mutant gene,[(B6×D2)F1 ×B6] N2 mutant mice were bred,and the genome of the N2 mice was scanned by microsatellite markers distributed equally on the mouse chromosome.The microsatellite linked to the mutant gene was determined by the log odds score.This experimental procedure was approved by Ethic Committee about Experimental Animal Care and Use of Yangzhou University.Results The founder mouse,which was the progeny of an ENU-treated B6 male mouse and an untreated B6 female mouse,had a corneal opacity phenotype.After mating the mutant with B6 mice,19 of 59 descendants appeared corneal opacity phenotype.Thickening of corneal stroma,neoangiogenesis,infiltration of inflammatory cells and proliferation of fibroblasts were exhibited in cloudy cornea in ENU-induced mutated mice under the optical microscope.After linkage analysis between microsatellite markers and the mutant gene,the mutant gene was linked to D2Mi307,which was located at 63.42 cM.Three cases of 26 N2 mice underwent recombination with the LOD 3.79.The mutant gene associated with the cornea phenotype was located on chromosome 2.Conclusions This study map the mutant gene associated with the cornea phenotype on chromosome 2.The strain might be used as a mouse model for heritable human corneal opacity.

Objective To study the expressions of B7-H1 and PD-1 which are costimulatory molecules in the pathogenesis of chronic hepatitis B (CHB). Methods The heparin anticoagulant blood samples from 11 CHB patients and 16 healthy controls were collected. The expressions of B7-H1 and PD-1 on myloid dendritic cells (mDC) and T lymphocytes in the peripheral blood were analyzed by flow cytometry. The data comparison was done by t test. Results The expressions of B7-H1 on CD3~+ ,CD4~+ , CD8~+ T lymphocytes and mDC in CHB patients were (40. 69± 14. 49)%, (42. 84 ±11. 19)%,(33. 48±14.07)% and (16. 60±4. 04) % , respectively, and those were (14. 66±10. 11) % , (4. 62±3.84)%, (1.89±2.31)% and (0. 49±0. 37)% , respectively in healthy controls. The expressions of B7-H1 on T-lymphocytes and mDC in CHB patients were significantly higher than those in healthy controls, and the differences were significant (t=-2.884,t=-10.894, t=-7.378, t=-13. 182,respectively; all P<0. 05). The expressions of PD-1 on CD3~+ , CD4~+ and CD8~+ T lymphocytes in CHB patients were (12. 45±6. 36)%, (11. 42 ± 6. 20)% and (13. 03± 6. 71) %, respectively, and those were (7. 80±3. 53)%, (7. 12±2. 60)% and (7. 88±3. 74)% , respectively in healthy controls.The expressions of PD-1 on T lymphocytes in CHB patients were significantly higher than those of the healthy controls, the differences were significant (t = -2.323, t =- 2. 355, t =- 2. 439,respectively) all P<0. 05). Conclusion The expressions of B7-H1 and PD-1 on T lymphocytes and mDC in CHB patients are higher than the healthy people.

Objective To study the expressions of Cx43,CD105 and VEGF in HBV related HCC tissues and the relationships between Cx43 expression and recurrence and prognosis after cancer radical resection in HCC patients stratified by serum AFP levels. Methods The expressions of Cx43,CD105,VEGF in 234 HBV related HCC tissues were examined by tissue microarray and two-step methods of PV-6000 of immunohistochemistry and the expressions of Cx43 in 20 frozen HCC specimens were examined by RT-PCR. Results Cx43 in HCC tissues was positive as examined by both immunohistochemistry and RTPCR methods.Positive Cx43 expression is correlated with lower early recurrence ( Log Rank P =0.001 ),longer disease free survival (Log Rank P =0.026 ) and overall survival( Log Rank P =0.000 ) as showed by the Kaplan-Meier analysis in patients with AFP ＜ 400 μg/L. The expression of Cx43 is an independent prognostic factor.The positive expression of Cx43 related with lower positive expression of CD105 and VEGF (P =0.018,0.023 ),and correlated with histological differentiation (P =0.002),the number of focus (P =0.033 ),blood vessel tumor embolism ( P =0.029 ). Conclusions The expression of Cx43 is correlative with the expression of CD105 and VEGF,and is predictive of HCC early recurrence and poor prognosis after radical hepatectomy in HBV related HCC patients with serum AFP ＜ 400 μg/L.

Aim To investigate TY501′s role in bleo-mycin ( BLM )-induced pulmonary fibrosis in rats. Methods Forty rats were randomly divided into 5 groups, including the sham operation, BLM, PFD, TY501(high and low dose) groups. After administra-tion of BLM intratracheally, PFD and TY501 were giv-en in each group daily, according to the dosage de-signed during 21 days. Lung coefficient, PaO2 were tested before killing the rats. The contents of ALB, ALP, LDH, GSH, HYP were detected by regent kit respectively. PCⅢ and COL4 were determined by ELISA. Results ( 1 ) Some indicators of alveolitis in early stage of IPF: the contents of lung coefficient in three treatment groups were lower and PaO2 was higher than those in BLM group ( P<0. 05 ); compared with BLM group, the contents of ALB, ALP, LDH in the treatment groups reduced on 21 st day ( P<0. 05 );the expression of GSH in BLM group was increased for feedback regulation and higher than the treatment groups and the sham operation group (P<0. 05);(2) some indicators of pulmonary interstitial fibrosis in late stage of IPF:the expressions of HYP, PCⅢand COL4 were reduced after the treatment. There were signifi-cant differences compared with BLM group ( P <0. 05 ) . Conclusions TY501 is valuable for the ther-apy of IPF, the same as the positive drug pirfenidone. TY501 attenuates BLM-induced pulmonary fibrosis, which may be related to the affection of TGF-βpathway and inhibition of MMPs.
