Objective To study the genetic toxicity of surfactants Tween-20?Tween-80?Span-20?BE-2. Methods To take root tip cells of Vicia faba as the subjects, treated with various concentrations of surfactants to study the effect of them on the micronucleus and chromosome aberration in root tip cells of Vicia faba. Results The frequencies of micronucleus cell induced by surfactants Tween-20?Tween-80?Span-20?BE-2 were (21.34?1.31)‰, (13.44?2.66)‰, (15.29?3.16)‰ and (7.53?2.34)‰ respectively, the frequencies of chromosome aberration induced by surfactants Tween-20?Tween-80?Span-20?BE-2 were (18.16?0.50)%, (11.05?1.18)%, (23.79?1.62)% and (22.58?0.61)%, significant differences were seen compared with the control. Conclusion The results of the present paper demonstrates that surfactants Tween-20?Tween-80?Span-20?BE-2 have the effect of mutagenic agent.

Objective To study the changes of cerebral haemodynamics in neonates with hypoxic-ischemic encephalopathy(HIE) treated with Shengmai injection compared with citicoline,and explore the clinical interventions of Shengmai injection on HIE.Methods Fifty patients with HIE were randomized into 2 groups: shengmai group treated with Shengmai injection(n=30),and citicoline group treated with citicoline(n=20).The haemodynamic parameters included peak systolic flow velocity(PSFV),end-diastolic flow velocity(EDFV),pulsation index(PI) and resistance index(RI) of anterior and middle cerebral artery were detected by color Doppler ultrasound before treatment and on 7~(th) day after treatment respectively.Control group(n=50) compared with the two groups.Results PSFV,PDFV and RI of HIE patients were significantly lower than those of control group(P

Objective: To optimize matrix composition and technology for Jiefushuang Emulsion. Methods: Orthogonal design was used, oil phase, agitation velocity, emulsifiers and emulsify temperature were selected as variable factors. Results: The optimum matrix composition and technology were: The ratio of oil to water was 2∶3, emulsifiers: 320g(oil 500mL), HLB: 15, emulsity temperature: 70?C , agitation velocity: 800 revolutions per minute, lasting for 20 minutes. Conclusion: The emulsion prepared accords with the stipulation of the appendix of Chinese pharmacopoeia (2000).

Objective To test the content of menthol in Chuanbei Pipa Syrup(CPS)by GC, and to evaluate its quality. Meth-ods The content of menthol in CPS was determined by capillary gas chromatography. DB-WAX capillary column (30 m ×0. 319 mm × 0. 50μm) was used with nitrogen as carrier gas. The precolumn pressure was 500 kPa and the column temperature was at 110 ℃ with split ratio of 25 : 1. The temperature was set at 250℃ for sample injection and for the detector. Results The content of menthol in CPS produced by Henan Pharmaceutical Co. , Ltd. , Zhengzhou Pharmaceutical Co. , Ltd. and Yunan Pharmaceutical Co. , Ltd. was 0. 154 mg/mL, 0. 203 mg/mL and 0. 109 mg/mL, respectively. Of them, the men-thol content in CPS produced by Zhengzhou Pharmaceutical Co. , Ltd. met the requirements of Pharmacopoeia(2005 edition), and that of the other two species was slightly lower. Conclusion The methods are convenient, reliable and accurate for the de-termination of menthol content in Chuanbei Pipa Syrup.

Objective To evaluate the association between cytomegalovirus (HCMV) infection and atherosclerosis (AS) and explore the possible role of endothelin (ET) and serum tumor necrosis factor(TNF ?) in the pathogenesis of AS in diabetic patients and the relationship between HCMV infection and concentrations of ET and TNF ?. Methods Blood samples were collected from 21 patients with AS of type 2 DM, 47 patients with non AS of type 2 DM and 20 controls. Special antibodies to HCMV (IgM,IgG) were measured by enzyme linked immunosorbent assay (ELISA) . The concentrations of serum TNF ? and plasma ET were determined by RIA. Results (1) Type 2 diabetic patients, especially those with established AS, had a higher prevalence of active infection of HCMV. (2) The levels of plasma ET and serum TNF ? in type 2 diabetic patients were higher than those in normal people. In the pathogenesis of AS in diabetic patients, the ET played more important role than the TNF ?.(3) There was a significantly positive correlation between anti IgM to HCMV and the level of plasma ET in type 2 DM patients. It suggested that the injury of endothelium cell was related to the active infection of HCMV. Conclusion The study suggests that HCMV infection may be important in the pathogenesis of AS in type 2 diabetic patients and ET possibly plays an important role on the pathological course of AS.

Objective To discuss the clinical significance of nephroscopic surgery for simple renal cysts. Methods A 2~4 cm incision was made below the 12th costal interspace. Through the incision the nephroscopic decortication was performed in 26 patients with simple renal cyst. Results The operation time was 20~80 min (mean, 30 min) and the postoperative hospital stay, 3~)6 days (mean, 4 days). No blood transfusion was required and no severe complications were noted. Follow-up observations for 3~)12 months (mean, 8 months) in the 26 patients found no recurrence. Conclusions Mini-incision nephroscopic decortication for renal cysts is feasible and mini-invasive, with advantages of simplicity of performance and quick postoperative recovery.

[Objective] To summarize Prof. YANG Jinkun gastric cancer clinical experience of diagnosis and treatment, in order to promote clinical application.

Objective To know the current status and its main influential factors of overweight and obesity among residents in Gushan county, Fuzhou city. Method The population aged above 20 years old was sampled by multistage sampling. Back- ground information was collected by face-to-face interview. Data on weight and height was obtained through physical check-ups. Results There were 2 412 objects were interviewed and physically measured.
