After 28 foreign species of AM fungi were inoculated in sterilized soil, the effects of the AM mycorrhizal colonization and the medicine quality of Paris polyphylla var. yunnanensis were observed by combination of inoculation test in pot at room temperature and instrumental analysis. The results showed that, compared with control group (CK), the inoculation of foreign AM fungi in the soil influenced the spore density, mycorrhizal infection rate, and colonization intensity of AM fungi in root system of P. polyphylla var. yunnanensis. The inoculation of foreign AM fungi enhanced the mycorrhiza viability of P. polyphylla var. yunnanensis by increasing the activity of succinic dehydrogenase (SDH) and alkaline phosphatase (ALP) in intraradical hyphae. The content of single steroid saponin in rhizome of P. polyphylla var. yunnanensis showed variation after P. polyphylla var. yunnanensis was inoculated by different foreign species of AM fungi, which was beneficial for increasing the medicine quality; however, the kinds of steroid saponin showed no difference. In a degree, there was a selectivity of symbiosis between P. polyphylla var. yunnanensis and foreign AM fungi. And we found that the Claroideoglomus claroideum and Racocetra coralloidea were best foreign AM fungi species for cultivating P. polyphylla var. yunnanensis under field condition.

OBJECTIVETo investigate the changes of the mRNA expressions of myocardial cytoskeletal proteins in endotoxemic rats.

METHODSThirty-seven Wistar rats were randomized into two groups with injection of 10 mg/kg lipopolysaccharide (LPS) or normal saline through the femoral vein. The cardiac function of the rats was monitored continuously for 24 h, and the morphological changes of the cardiac myocytes were observed with HE staining and electron microscope. The mRNA levels of myocardial cytoskeletal proteins including actin, tubulin and desmin were determined by RT-PCR.

RESULTSNo significant difference was found in the number of CD3(+)T lymphocytes in the TILs between different groups. After the immunotherapy, the peLPS injection resulted in significant impairment of the cardiac function and myocardial microstructure of the rats with reduced heart rate and left ventricular systolic pressure (LVSP). The mRNA expression of actin in the cardiac myocytes measured by fluorescence optical density was reduced significantly 8 h after LPS injection, and that of tubulin was decreased significantly 24 h after LPS treatment; desmin mRNA expression showed no significant variation after LPS injection.

CONCLUSIONLPS can significantly impair the cardiac function of the rats possibly by inducing damages of the myocardial cytoarchitecture and causing changes in the mRNA expressions of such cytoskeletal proteins as actin and tubulin.

Objective To evaluate high resolution manometry in the diagnosis of hiatal hernia.Methods Clinical data were reviewed on 20 patients suffering from gastroesophageal reflux who had laparoscopic Toupet fundoplication for preoperative tentative diagnosis of hiatal hernia.Preoperative diagnosis of hiatal hernia was made collectively by endoscopy,X-ray examination,24 hour esophageal pH monitoring and high resolution manometry before surgery.Results Preoperative diagnosis of hiatal hernia was made in 3 patients by X-ray examination,in 9 patients by high resolution manometry.11 patients were finally diagnosed with hiatat hernia intraoperatively.X ray was consistent with intraoperative diagnosis in 27％ cases.Intraoperative and endoscopic diagnoses were 55％.High resolution manometry and intraoperative diagnoses were consistent in 82％.Lower esophageal sphincter length was (1.92 ± 0.38) cm in hiatal hernia group and (2.10 ± 0.92) cm in non-hiatal hernia group (t =0.60,P ＞ 0.05),lower esophageal sphincter pressure (respiratory min) was (0.64 ±0.55) kPa in hiatal hernia group and (1.31 ± 1.07) kPa in nonhiatal hernia group(t =1.80,P ＞ 0.05),and lower esophageal sphincter pressure (respiratory mean) was (1.43 ±0.92) kPa in hiatal hernia group and (2.57 ± 1.33) kPa in non-hiatal hernia group(t =2.26,P ＜0.05).The reflux parameters,including the percent total time pH ＜ 4,and DeMeester score,were significantly greater in hiatal hernia group than in non-hiatal hernia group (all P ＜ 0.05).Conclusions Hiatal hernia patients are with poor esophageal antireflux competency and severe reflux.High resolution manometry is more valuable in the diagnosis of hiatal hernia than endoscopy or X-ray examination.

Objective To evaluate the effects of sevoflurane on the expression of heparanase ( HPA) and fascin in lung carcinoma cells of mice. Methods Mouse LLC cells were inoculated in the culture plate. After being cultured for 24 h, the cells were equally and randomly divided into 4 groups using a random number table: control group ( group CC) , 1% sevoflurane group ( group Sev1 ) , 2% sevoflurane group ( group Sev2 ) , and 3% sevoflurane group ( group Sev3 ) . Cells in Sev1-3 groups were exposed to 1%, 2% and 3% sevoflurane, respectively, for 4 h, while cells in group CC were not exposed to sevoflurane, and all the cells were then cultured for another 24 h in an incubator. The invasion of cells was determined by Transwell invasion assay, and the invaded cells were counted. The migration of cells was determined by wound healing assay, and cell migration rates were calculated. The expression of HPA and fascin in cells was detected by Western blot. Results Compared with group CC, the number of invaded cells and cell migration rates were gradually decreased, and the expression of HPA and fascin was gradually down?regulated with increasing concentrations of sevoflurane in Sev1-3 groups. Conclusion The mechanism through which sevoflurane inhibits the metastasis of mouse lung carcinoma cells is associated with down?regulated expression of HPA and fascin.
