    Objective To investigate the preventive effects of panax notoginseng saponins (PNS) on postoperative peritoneal adhesion in mice. Methods The peritoneal adhesion in mice was induced by abrasing cecum serosa membrane. 120 mice were divided randomly into five groups, such as the control, urokinase and PNS (1.5, 3.0, 6.0 mg) groups. The mice were treated locally with normal saline 0.5 mL, urokinase 80 U, PNS 1.5, 3.0, 6.0 mg, respectively. The development of peritoneal adhesion, local fibrous connective tissue and collagen tissue were observed with unaided eye at the 15th day postoperatively. Results All mice in the control group suffered peritoneal adhesion with Ⅲ or Ⅳ grade. PNS (3.0, 6.0 mg) and urokinase decreased the formation of peritoneal adhesion, local fibrous connective tissue and collagen tissue significantly. Meanwhile, 1.5 mg PNS only improved peritoneal adhesion(P>0.05). Conclusion PNS could efficiently decrease the incidence and severity of postoperative peritoneal adhesion in mice.

    Objective To study the influence of iohexol on the phase behavior of thermosensitve poly(N-isopropylacrylamide-co-butyl methacrylate) (PNIP/BMA) nanogel for preparing a novel radiopaque in situ gelable thermosensitive nanogel. Methods The influence of Iohexol on the volume phase transition of PNIP/BMA nanogel particles was investigated by dynamic light scattering. The effect of iohexol on the thermosensitive phase behavior of in situgelable PNIP/BMA nanogel dispersion was studied by vial inverting method and viscosimeter. Results PNIP/BMA nanogel particles dispersed in iohexol injection were in shrunken state at lower temperature and the average diameter of PNIP/BMA nanogel particles increased first, then decreased slightly and followed by increasing induced by hydrophobic aggregating with the temperature increase, which was different from that of PNIP/BMA nanogel dispersed in pure water. The concentrated PNIP/BMA nanogel became semitranslucent swollen gel near the body temperature with iohexol being higher than 175 mgI&#8226;mL1. The viscosity of nanogel dispersion containing iohexol was higher than that of aqueous dispersion without iohexol under the same condition. Conclusion iohexol has profound effects on both the volume phase transition of PNIP/AAm nanogel particles and phase behavior of PNIP/AAm nanogel dispersion.

    Objective To investigate the relationship between the Shortterm Fever of Unexplained Origin (SFUO) and pulelin injection by the casecontrol study and retrospective cohort study, and analyze the difference between incidence of fever caused by different puerarin injections before GMP and after GMP authenticated. Methods The eligible patients with cardiaccerebrovascular disorders among the first affiliated hospital of wenzhou medical college, the second affiliated hospital of wenzhou medical college and Wenling affiliated hospital after 2001 were selected, and were divided into an exposed group (tianbaokang and purun injections) and a nonexposed group (received other medicines). The incidence of SFUO, the relative risk (RR) and attributive risk (AR) were calculated, respectively, and the difference of incidences of SFUO in exposed to Puerarin, tianbaokang and purun of pulelin injections were analyzed. Results There was no significant difference between tianbaokang(6.31%) and purun(5.66%) (P>0.05), which suggested that there was no causality between SFUO and tianbaokang or purun injections. However, compared with the incidence of pulelin injection(26.73%), there was marked difference of SFUO between pulelin and tianbaokang or purun injections(P<0.01). Conclusion No evidence could indicate that tianbaokang injection and purun injection, both were Puerarin injections resent appeared in the market, were related to SFUO. The use of the same Chinese traditional Puerarin injections from various periods could result in completely different outcomes. Therefore, the serious side effects such as SFUO could eliminate and the safety of drugs could increase by improving pharmaceutical quality management.
