OBJECTIVE: To investigate the lethal blood level, the target organs and tissues, the toxicant storage depots and the postmortem redistribution in mice died of emamectin benzoate poisoning. METHODS: The mice model of emamectin benzoate poisoning was established via intragastric injection. The main poisoning symptoms and the clinical death times of mice were observed and recorded dynamically in the acute poisoning group as well as the sub-acute poisoning death group. The pathological and histomorphological changes of organs and tissues were observed after poisoning death. The biodistribution and postmortem redistribution of emamectin benzoate in the organs and tissues of mice were assayed by the enzyme-linked immunosorbent assay (ELISA) at 0h, 24h, 48h and 72h after death. The lethal blood concentrations and the concentrations of emamectin benzoate were detected by high performance liquid chromatography (HPLC) at different time points after death. RESULTS: The symptoms of nervous and respiratory system were observed within 15-30 min after intragastric injection. The average time of death was (45.8 ± 7.9) min in the acute poisoning group and (8.0 ± 1.4) d in the sub-acute poisoning group, respectively. The range of acute lethal blood level was 447.164 0-524.463 5 mg/L. The pathological changes of the organs and tissues were observed via light microscope and immunofluorescence microscope. The changes of emamectin benzoate content in the blood, heart, liver, spleen, lung, kidney and brain of poisoning mice showed regularity within 72 h after death (P < 0.05). CONCLUSION The target organs of emamectin benzoate poisoning include heart, liver, kidney, lung, brain and contact position (stomach). The toxicant storage depots are kidney and liver. There is emamectin benzoate postmortem redistribution in mice.

Objiective To evaluate the histocompatibility of gelatin-bletilla/Salvia-miltiorrhiza i material and to discuss the appropriate concentration of salvia-miltiorrhiza in the material. Method Salvia-miltiorrhiza together with gelatin and bletilla was used to make a kind of porous membranes. A total of 175 rats were divided randomly (random number) into 5 groups ( n = 35 in each). The porous membranes containing salvia-miltiorrhiza material in different concentrations of 1, 2, 4, and 5 mL/100 g were implanted subcutaneously into the rats of the four experimental groups, respectively. The gelatin-bletilla material without salvia-miltiorrhiza was implanted into the rats of control group. In 1, 3, 7, 14, 21, 28 and 56 days after implant, the materials were taken out of the bodies of the rats, separately. The material implanted for 1, 3, 7 and 14 days were observed with immunohistoche-mistry. Results In the area of implant, no noticeable inflammation or other was found. The implanted materials were degraded and entirely absorbed in vivo in 8 weeks. The salvia-miltiorrhiza in concentration of 2 mL/100 g in vivo promoted the angiogenesis most significantly. Conclusions The gelatin-bletilla/salvia-miltiorrhiza material has excellent histocompatibility and the appropriate concentration of salvia-miltiorrhiza in material is 2 mL/100 g.

In order to search for a new pathway to improve the yield of ginseng through growing at the full sun shine accompanied by salicylic acid (SA), the net photosynthetic rate (P(n)), superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), malondialdehyde (MDA) in Panax ginseng leaves, and the content of ginsenosides in roots were compared under various concentrations of SA and full sun shine with the traditional shade shed. Under the full sun shine, 0.05, 0.2 mmol x L(-1) SA increased net photosynthetic rate to a great extent. Under the cloudy day, the average net photosynthetic rate increased by 127.8% and 155.0% over the traditional shade shed, 13.9% and 27.5% over the treatment without SA respectively; under the clear day, 23.5% and 30.4% over the traditional shade shed, 8.6% and 14.6% over the treatment without SA, particularly obvious in the morning and late afternoon. With such concentration, SA increased activities of SOD, CAT, POD, and decreased the contents of the MDA. This difference resulted from different light intensity, rise of light saturation point, and fall of compensation point. Full sun shine decreased ginsenosides contents, but with SA, the ginsenosides regained, the content of Rg1 and Re, Rb1, total six types of ginsenosides in SA 0.2 mmol x L(-1) group were higher than those in the control group (P < 0.05) and other groups. The application of 0.2 mmol x L(-1) SA under full sun shine during a short time has little threat to the P. ginseng in spring, and could enhance the resistance to the adversity, which would improve the yield of ginseng heavily.

Objective To evaluate the clinical outcomes of external fixator with lumbopelvic distraction spondylodesis in treatment of vertically unstable pelvic fractures. Methods From January 2008 to March 2009, 9 patients (4 males and 5 females) with a vertically unstable pelvic fracture were treated with modular external fixator with lumbopelvic distraction spondylodesis. According to the classification of Tile, 9fractures were classified as type C. This fixation construct comprises a vertical lumbopelvic distraction component which fixed L4.5 and the posterior superior iliac spine and a transverse fixation which fixed anterior iliac spine with external fixator. Results All patients were followed up 12-18 months after surgery, with an average of 14.3 months. Postoperative X-ray showed satisfactory reduction of pelvic fracture. Pelvic fractures healed in all patients without loss of reduction 3-6 months after operation. According to Matta reduction evaluation criteria, 6 patients were excellent and 3 good. For the two patients with sacral neurological injuries,appropriate surgical decompression was performed to improve the symptom and minimize the deformity. No iatrogenic complications of neurovascular injury occurred. Patients now walk unassistedly without pain in the waist or legs, and with no shortening of lower limbs or claudication. By considering symptom and satisfactory scores, the Majeed functional assessment revealed that seven patients had excellent results and two good at one year. Conclusion External fixator with lumbopelvic distraction spondylodesis that allowed early mobilization and ambulation, with general applicability and definite safety, is an effective surgical technique for the treatment of vertically unstable pelvic fracture.

ObjectiveTo investigate the association of single nucleotide polymorphisms (SNPs)of rs11833579 and rs12425791 on chromosome 12pl3 with cerebral infarction in the Fujian Han population.MethodsA case-control association study containing a total of 216 cases and 279 controls was carried out.The genotypes of two polymorphisms were evaluated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and direct DNA sequencing followed by association analysis.Results The frequency of G ＞ A genotype of rs12425791 in patients with cerebral infarction was lower than that in the controls (34. 3％ vs 43.4％ , x2 = 4. 298 ,P ＜ 0. 05 ) after stratified by causes of cerebral infarction, there was no significant difference in this genotype between large-artery atherosclerosis and controls.Association analysis was performed by logistic regression model after adjusting by sex, age, hypertension, diabetes mellitus, dyslipidemia, smoking and drinking.
