Objective To study the effect of lumbrokinase treatment on hemorheology, glucose and lipids of type 2 diabetes mellitus (T2DM). Methods 76 cases with T2DM whose blood glucose was controlled at FPG<8mmol/L and 2hPG<11mmol/L were involved in the study. All patients were divided into two groups:lumbrokinase (600ku tid for eight weeks) group (n=40) and control group (n=36). The levels of the blood rheology, glucose and lipids were measured. Results The levels of the whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate and triglyceride were decreased in lumbrokinas group as compared with control groups (all P<0.01).There were no differences in FPG and 2hPG between two groups(P>0.05). Conclusions Lumbrokinase can decrease the levels of the blood rheology and triglyceride in T2DM. It may prevent and cure the complication of diabetes mellitus

The paper analyzes the status of pathology teaching in clinical medicine graduates and the necessity to strengthen clinical pathology general education. Then it proposes measures about enhancing clinical pathology general education, so as to increase the basic clinical pathology knowledge of medical grad-uates.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on bone mineral density (BMD) and expression of calcium transport-related receptors in ovariectomized rats, so as to explore its mechanisms underlying improvement of osteoporosis. METHODS: Thirty-two three-month female SD rats were randomly divided into control, sham operation, model and EA groups (n=8 in each group). The ovariectomy model was established by resection of bilateral ovaries. EA (2 Hz/15 Hz, 2 mA) was applied to "Guanyuan"(CV4)+"Sanyinjiao"(SP6) or "Shenshu"(BL23)+"Housanli"(ST36) alternatively for 20 min, once daily (except the weekends) for 12 weeks. BMD of the tibia and femur were detected by using a bone densitometer. The expression levels of transient receptor potential vanillic receptor 5 (TRPV5), transient receptor potential vanillic receptor 6 (TRPV6), sodium calcium exchanger 1 (NCX1), membrane calcium adenosine triphosphate hydrolase (PMCA1b), zonula occludens 1 (ZO-1), occludin and claudin in intestinal mucosa were detected by quantitative real-time PCR and Western blot, respectively. RESULTS: Following modeling, BMD of both tibia and femur, and expression levels of TRPV5, PMCA1b, ZO-1, occludin and claudin mRNAs were significantly decreased in the model group compared with the control and sham operation groups (P<0.05, P<0.01)，while the mRNAs levels of TRPV6 and NCX1 in the model group were increased (P<0.01). After the treatment, BMD of both tibia and femur, and expression levels of TRPV5, PMCA1b, ZO-1 and occludin mRNAs were significantly increased(P<0.01，P<0.05)，and TRPV6 and NCX1 were significantly decreased(P<0.01，P<0.05) in the EA group than those in the model group. Compared with the control and sham operation groups, protein expression levels of TRPV5, PMCA1b, ZO-1, occludin and claudin in the model group were significantly decreased (P<0.05), while the protein levels of TRPV6 and NCX1 in the model group were increased (P<0.05). After EA intervention, modeling-induced decrease of TRPV5, PMCA1b, ZO-1, occludin and claudin protein levels and increase of TRPV6 and NCX1 protein levels were all completely reversed in the EA group relevant to the model group (P<0.05). CONCLUSION: EA intervention can improve bone mineral density and up-regulate the mRNA and protein expression of TRPV5, PMCA1b, ZO-1 and occludin, which may be one of the mechanisms of acupuncture in the treatment of osteoporosis.

Objective:To investigate polymorphism of human leukocyte antigen (HLA)-DRB1 and -DQB1 genes in Bai ethnic group in Dali,Yunnan province.Methods:Polymerase chain reaction-sequence specific primers (PCR-SSP) were used to determine HLA-DRB1 and -DQB1 alleles in 124 unrelated healthy Bai ethnic individuals living in Eryuan County of the Dali Bai autonomous prefecture,Yunnan province.Results:Among all the 21 DRB1 alleles and 15 DQB1 alleles were identified,the predominant alleles were DRB1*1202(26.61%),DRB1*0901(13.89%) and DRB1*0803(9.92%) on DRB1 locus and DQB1*0301(31.45%),DQB1*0601(10.08%),DQB1*0401(8.06%)and DQB1*0502(8.06%)on DQB1 locus.The most common haplotypes were DRB1*1202-DQB1*0301(20.08%)and DRB1*0803-DQB1*0601(7.19%).Conclusion:The phylogenetic tree constructed according to the HLA-DRB1,-DQB1 allele frequencies of Bais with those of other 10 populations suggests that the Bai ethnic group belongs to the southern group of China,but it keeps genetic distance from others and the HLA genes exhibits a unique profile.This study would provide HLA polymorphism information of Bai for the future investigation on the disease related to the genetic polymorphism.

OBJECTIVE: To investigate the proteome of hepatocyte transformation by hepatitis C virus (HCV) nonstructural protein 3 (NS3). METHODS: Human hepatocyte line QSG7701 stably expressing HCV NS3 C-terminal deleted protein was constructed, which was named pRcHCNS3/QSG. Two-dimensional electrophoresis (2-DE) was used to separate the total protein of pRcHCNS3/QSG and pRcCMV transfected cells (pRcCMV/QSG) respectively. Differentially expressed protein spots were identified by mass spectrometry. Western blot confirmed the differentially expressed proteins. RESULTS: 2-DE profiles with high resolution and reproducibility were obtained. The average spots of pRcHCNS3/QSG and pRcCMV/QSG were (1183+/-77) and (1095+/-82) respectively, and (920+/-60) spots were matched. Twenty-one differentially expressed protein spots were chosen randomly and 15 were identified by mass spectrometry. Some proteins such as Ras, P38 and HD53 which were involved in signal transduction were increased in pRcHCNS3/QSG cells. Western blot also showed strong expression of phosphorylated P44/42 and P38 in pRcHCNS3/QSG cells. Other differentially expressed proteins were related to cell cycle regulation, immunoreaction, tumor invasion and metastasis, and liver metabolizability. CONCLUSION HCV NS3 might be involved in cell malignant transformation through affecting protein expression and signal transduction such as MAPK cascade. Further study on the signal transductions and their relationship would not only be helpful to explore the mechanism of HCV related HCC, but also provide a new idea for the molecular treatment of HCC.

BACKGROUNDInterleukin (IL)-27 has been reported to have anti-proliferate and anti-angiogenic activities on cancer cells. However, the involvement of IL-27 in malignant pleural effusion (MPE) remains unknown. Thus, in this research, we compared the immune functions of IL-27, interferon (IFN)-γ, and IL-17 on lung cancer cells and revealed the regulatory mechanism of IL-27 in MPE.

METHODSThe distribution of IL-27 in both MPE and blood was evaluated by enzyme-linked immunosorbent assay and flow cytometry. The expressions of cytokine receptors and the levels of the phosphorylated signal transducer and activator of transcription (STAT) signalings were detected by flow cytometry. As well as the effects of proliferation, apoptosis, migration, and adherent activity of IL-27, IFN-γ, and IL-17 on lung cancer cells were also explored.

RESULTSThe expression of IL-27 was increased in MPE when compared with blood (147.3 ± 25.1 pg/ml vs. 100.3 ± 13.9 pg/ml, P = 0.04). IL-27 was noted to suppress both proliferation (18.33 ± 0.21 vs. 27.77 ± 0.88, P = 0.0005) and migration (1.82 ± 0.44 vs. 3.13 ± 0.07, P = 0.04) of A549 cells, but obviously promoted apoptosis of A549 cells (9.47 ± 1.14 vs. 4.96 ± 0.17, P = 0.02) by activating STAT1 signaling. Interestingly, IL-27 played totally opposite effects on A549 cells by activating STAT3 pathway. Moreover, IL-27 exerted different intercellular adherent activities of A549 cells to pleural mesothelial cell monolayer by activating different STAT signalings.

CONCLUSIONSIL-27 might exert an important immune regulation on lung cancer cells in human pleural malignant environment.
