AIM: To study the pharmacodynamic effect of Chanfuan Oral Solution. METHODS: Acute blood stagnation caused by adrenaline, ankle swelling, ear edema and writhing caused by acetic acid were taken for experiment models. RESULTS: Chanfuan Oral Solution could significantly reduce blood viscosity. Results also showed that it had inhibitory effect on rat's ankle swelling, ear edema and reduction in ratio of writhing of mice. CONCLUSION: These results suggest Chanfuan Oral Solution is an effective drug for reducing blood viscosity, anti inflammation and analgesia.

Objective To evaluate clinical features, therapeutic regimen and prognosis of unexplained rhabdomyolysis. Method Clinical manifestations, therapeutic regimen and prognosis were recorded in 23 patients,who were admitted to The First Affiliated Hospital of Nanjing Medical University 13 to 27 August,2010.The 23 patients were diagnozed as unexplained rhabdomyolysis. Results The patients all presented myalgia of upper body,like neck,waist and back,maybe with asthenia, nausea,dyspnea,abdominal pain, red urine or changed color of urine. Laboratory examination: obviously step-up of creatine kinase [CK: (4655 ± 2556) U/L( normal: 25 ～ 190U/L) AST:(141 ±78) U/L(normal:10～45 U/L),LDH:(348± 127) U/L(normal: 110～ 250 U/L)]and myoglobin[( Mb ＞ 1000 μg/L (normal: 0 ～ 50 μg/L)]. Therapeutic regimen included treatment of the underlying diseases, volume repletion, alkalization and dealing with the complications. No patients developed acute renal failure.All the patients recovered. Conclusions Rhabdomyolysis is a syndrome with different clinical manifestations.However, early diagnosis, proper treatment could prevent serious complications,and prognosis is good.

Objective To detect the microvessel density(MVD) marked by MIF protein in esophagus squamous cell carcinoma(ESCC), and to see if a relationship exists between microvessel density(MVD) and clinicopathologic features. Methods The expression of MIF in vascular endothelial cell in forty ESCC specimens was examined by immunohistocbemistry staining, calculated the mean of MVD and analysed the relationship with clinicopathologic features. Results The positive rate of MIF protein was 95.00 %(38/40) in ESCC vascular endothelial cell. Compared with the normal esophageal squamous tissue[32.50 %(13/40)], there was significant difference in statistics, the mean of MVD was 26.5±8.5. MVD was positively correlated with the tumor TNM stages and lymph node motastasis. Conclusion MIF can be used in tagging vascular endothelial cell, MVD of ESCC was positively correlated with the tumor TNM stages and lymph node metastasis. It might be an major prognostic factor in ESCC.

Objective:To analyze the effect of PAK4 interruption by microRNA-199a/b-3p (miR-199a/b-3p) on migration and invasion of hepatocellular carcinoma (HCC).Methods: To test targeting of PAK4 by miR-199a/b-3p,we used luciferase assay in HEK293T cells cotransfected miR-199a/b-3p mimcs and pmirGLO-PAK4 3′UTR.The expression of PAK4 in SMMC-7721 transfected with miR-199a/b-3p was detected by Western blot.The biology behaviors of SMMC-7721 cells transfected with miR-199a/b-3p or PAK4 Si were analysed by cell migration assay and invasion assay.Results:MiR-199a/b-3p could suppress the mRNA and protein ex-pression of PAK4 by targeting PAK4 3′UTR,and the downregulating PAK 4 expression suppress the migration and invasion of SMMC-7721 cells.Conclusion: MiR-199a/b-3p could suppress the expression of PAK 4, which are considered key HCC suppressors and inhibit the migration and invasion of HCC cells.

Lysozyme generally exists in animals,plants and microorganisms,and it is used as a natural anti?infection materi?al and one of the important non?specific immune factors in organisms. This paper reviews the progress of researches on its classifi?cation,gene structure and function,and expression regulation in Oncomelania hupensis,and on the factors affecting its activi?ties in recent years,in order to further discuss its distribution in O. hupensis.

Objective To observe the effects of Okinawa Habu apoxin protein-1 (OHAP-1) on the proliferation inhibition of rat C6 glioma cells and its mechanisms. Methods MTT colorimetric analysis was used to measure the inhibitory effect of OHAP-1 with different doses(2.5,5.0,and 10.0 mg?L-1) on C6 glioma cells .RT-PCR was used to evaluate the mRNA expressions of bcl-2 and bax genes.The activity of superoxide dismutase (SOD) and the level of maleicdialdehyde (MDA) in the C6 glioma cells were also examined. Results The proliferation of C6 glioma cells was significantly inhibited by different doses of OHAP-1(2.5,5.0,and 10.0 mg?L-1).The inhibitory rate were 49.77%,67.65%,and 76.42%,respectively.The inhibitory rate in 2.5,5.0, and 10.0 mg?L-1 groups were higher than that in control group(P

AIM: To explore the role of calcineurin i n th e expression of NF-?B and the neurotoxicity in cultured cortical neurons treate d with interleukin-1? (IL-1?) and NMDA. METHODS: The cultured rat cortical neurons were used in the expe riment, damage of neurons was induced by interleukin-1?(IL-1?) or excitator y amino acid (NMDA). The degree of neuron damage was examined with the methods o f MTT assay and LDH releasing rate assay, as well as the Annexin V and PI immuno fluorescence. The expression of NF-?B p65 on the neurons was tested by the West ern blot analysis. RESULTS: Viability of neurons was obviously lower in the IL-1? group and NMDA group respectively than that in control group (P0.05). Annexin V and PI immunofluoresc ence showed that IL-1? mainly induced the neuron apoptosis, and NMDA induced th e neuron necrosis. CONCLUSIONS: The calcineurin mediates the higher expression of N F -?B p65 and neuron damage induced by IL-1?, but not play a critical role in th e necrosis induced by NMDA in the cultured cortical neurons. These results indic ate that calcineurin is the key molecule in the apoptotic signaling pathway.
