Objective To investigate the genetic patterns of iris pigmentat mutation in the white hair black eye ( WHBE) rabbits.Methods To construct six two-generation families between WHBE rabbit and Japanese white rabbit, and the quantity of individuals had different eye colours in F1 and F2 generations were recorded and analyzed.Results χ2 test showed there was no significant difference between observed values and expected values in the mode of autosomal domi-nate inheritance ( P>0.05) , while there were significant differences between observed values and expected values in the autosomal recessive inheritance and sex-linked genetic pattern(P<0.05).Conclusions Iris pigmentat mutation in WHBE rabbit has a monogenic character due to autosomal dominant mutation.

The energy metabolism of septic patients is serious disorder.The major manifestation is protein degradation,the enhancement of glyconeogenesis and the adipose lipid mobilization.This may be link to abnormal ways of inflammatory media,the hormone secretion and ubiquitin-proteasome caused by sepsis.The discussion on high metabolic mechanism of sepsis,has great significance for guiding clinical practice,promoting targeted interventions and treatment measures and improving the prognosis of patients.This article summarized the progress on hyper metabolism in sepsis.

Objective To study effect of traditional Chinese medicine chrysanthemum decoction on RSV infection after A549 cells chemotactic factor.Methods Subjects from The Second Hospital Affilated To Suzhou University in recent days, 64 cases of patients diagnosed with RSV effected pneumonia by clinical examination, RSV infection A549 cell model was established and the infected cells were cultured, chrysanthemums with TCM decoction and conventional antiviral observed its effect on RSV infection cell survival, compared two groups of cell SAP was determined by ELISA kit and the expression of RANTEs and chemokines MCP-1.Results Chrysanthemum, according to the results of in vitro cell culture studies traditional Chinese medicine decoction had the effect of directly inhibit the growth of virus replication, and there were some positive effects RSV infected A549 cells, MCP-1 and RANTEs expression or release significantly increased ( P<0.05 ) .Chrysanthemum Chinese medicine decoction and antiviral drugs after the intervention, the expression of MCP-1 and RANTES reduced significantly (P<0.05), but overall volume was still significantly higher than the normal. Conclusion Chrysanthemum Chinese medicine decoction can inhibit RSV infected A549 cells release chemokine RANTEs and MCP-1 to some extent, and then reduce the airway inflammation reaction of children.

Mesenchymal stem cell (MSC) resides in a relatively hypoxia niche (volume fraction 1％～7％)compared to normoxia (20％).MSC cultured in hypoxia condition shows different biological features from those in normoxia condition.Hypoxia inducible factor-1 α (HIF-1 α),as one of main transcription factors in hypoxia,participates in the regulation of cell proliferation,differentiation,apoptosis,glycolysis and angiogenesis.Recent researches show that HIF-lα also plays an important role in regulating the survival,differentiation and migration of MSC.It turns out that hypoxia can improve survival and migration of MSC,enhance chondrogenesis but inhibit adipogenesis through HIF-lα and its downstream genes.However,whether hypoxia promotes or impedes osteogenesis remains controversial.Such differences can be caused by variances of tissue origination,oxygen concentration and culture condition.The comparison of different researches should be based on the same experiment condition.This review focuses on the influence of hypoxia on proliferation,apoptosis,differentiation and migration of MSC.

Objective To establish a method for the content determination of paeoniflorin in Gujing Pill. Methods Orthogonal test was used to optimize the condition of sample extraction and paeoniflorin content was detected by HPLC. HPLC was performed with Merck- LiChrospher RP- C18 column(4.6? 250 mm,5 ? m); methanol- water (25 ∶ 75) served as mobile phase and the detection wavelength was at 230 nm, the flow rate being 0.8 mL/min. Results Paeoniflorin has a good linearity within 0.27～ 1.35? g(r=0.9998) and the average recovery was 97.08 % with RSD 2.02 % (n=10). Conclusion This method is simple, sensitive, specific and can be used for the quality control of Gujing Pill.

Objective To explore the effects of low energy intravenous He-Ne laser irradiation of blood (ILIB) on cell proliferation, apoptosis and genotoxicity of lymphocytes in patients with cerebral infarction (CI). Methods The lymphocytes in peripheral blood in patients with CI were sampled before and after treatment and cultured, and then, some parameters such as the mitosis index (MI), cell cyclical kinetics index (CCKI), sister chromatid exchanges frequencies (SCEF) and apoptosis were analyzed in order to explore the effects of ILIB on lymphocytes. Results The proliferative activities of lymphocytes were significantly increased by ILIB (P0.05). After ILIB, the rate of apoptosis in patients with CI was significantly increased when compared with that before treatment and that of the control group, as revealed by flow cytometry (FCM) (P
