The relationship of nutrients and microorganisms in soils with polyphenols and total flavonoids of Houttuynia cordata were investigated by measuring nutrients, enzyme activity, pH, concentrations of microbe phospholipid fatty acids (PLFAs) in soils, and determining concentrations of polyphenols and total flavonoids of H. cordata. The research is aimed to understand characteristics of the planting soils and improve the quality of cultivated H. cordata. The soils at different sample sites varied greatly in nutrients, enzyme activity, pH, microbic PLFAs and polyphenols and all flavonoids. The content of total PLFAs in sample sites was following: bacteria > fungi > actinomyces > nematode. The content of bacteria PLFAs was 37.5%-65.0% at different sample sites. Activities of polyphenol oxidease, concentrations of available P and content of PLFAs of bacteria, actinomyces and total microorganisms in soils were significantly and positively related to the concentrations of polyphenols and total flavonoids of H. cordata, respectively (P < 0.05) . The Content of fungi PLFAs in soils was significantly and negatively related to concentrations of polyphenols and total flavonoids of H. cordata, respectively (P < 0.05). This study provides evidence that effectiveness of the soil nutrient, which may be improved due to transformation of soil microorganisms and enzymes to N and P in the soils, was beneficial to adaptation of H. cordata adapted to different soil conditions, and significantly affects metabolic accumulation of polyphenols and flavonoids of H. cordata.

Objective To investigate the effect of different Chinese herbs on cell proliferation and cartilage oligomeric matrix protein(COMP)expression in chondrocyte culture.Methods Chondrocytes isolated from rabbit knee cartilage were cultured for 3 generations with the density of 2?10~4/cm~2 and were verified by collagenⅡimmunohistochemical staining.Rabbit sera containing herbs were obtained after animals orally ad- ministrated herbs at the dosage equivalent to human.At 5% and 10% serum density,cells were cultured in the medium that contained liver-softening herbal compound sera.Subgroups setting at 1,3 and 5 hours after herb intervention were observed.Rabbit and bovine sera were control groups.Seven days after intervention,chon- drocytes proliferation was observed using the MTT assay kit.For the study of COMP expression,chondrocytes were isolated from human knee cartilage supematant.Superuatant COMP level was tested by enzyme-linked immunoabsorbent assays(ELISA)after directly adding compound and extract from liver-softening herbs to the culture at the final concentration of 10 mg/ml for 3 days.Results Liver-softening herbal compound group had significant effect on cell proliferation compared to control,of which,3-hour subgroup was more significant than 1-and 5-hour subgroups(P

OBJECTIVE: To analyze the rate of 235delC mutation in GJB2 gene in patients with idiopathic sudden hearing loss, and to explore its possible correlation with pathogenesis of idiopathic sudden hearing loss. METHOD: Two hundred and thirty-four patients with diagnosis of idiopathic sudden hearing loss in otolaryngology department were recruited as experimental group. Eighty people with normal hearing level were enrolled as control group. Their peripheral blood samples were obtained and genomic DNA was extracted. Using polymerase chain reaction, the coding region of GJB2 gene was amplified, and 235delC mutation is screened for in GJB2 gene by restriction endonuclease. At same time the clinical data of 234 patients was collected to analyze. RESULT: In 234 cases of idiopathic sudden hearing loss, 5 cases were found to have heterozygous 235delC mutation, none of them harbored homozygous 235delC mutation, the 235delC mutation rate was 2.1% (5/234). No 235delC mutation was found in control group. The rate of 235delC mutation in two group showed no statistically significant difference (P > 0.05). CONCLUSION This research shows that the rate of 235delC mutation in GJB2 is low in patients with idiopathic sudden hearing loss, and suggest that 235delC mutation possible has no correlation with idiopathic sudden hearing loss.

OBJECTIVETo investigate whole blood viscosity changes at different time points in rats model with lumbar vertebrae semidislocation, study Shi's theroy of qi and blood and "Gucuofeng and Jinchucao" [symbols: see text], also reveal pathological physiology characteristics of spinal disorder.

METHODSThirty-six SPF male rats weighted 350 to 450 g were randomly divided into rotatory fixation group (RF group), simple fixation group (SF group) and Sham group (Sham group), 12 rats in each group. Exterior vertebrae implanted through L4-L6 segments of lumbar vertebrae in RF and SF group were connected fixed device. In RF group, L5 spinous process were rotated to right, and caused L5 spinous process was non collinear with L4 and L6; in SF group, external fixed device were simple connected without rotation. At 1, 4, 8 and 12 weeks after fixation, whole blood viscosity changes were tested.

RESULTSAt 4 and 8 weeks after fixation, high (150/s), medium (60/s) and lower (10/s) shear rate in RF and SF group were higher than that of Sham group (P<0.05). At 1 and 12 weeks, there was no sigificant differences among three groups in whole blood viscosity (P>0.05).

CONCLUSION"Gucuofeng and Jinchucao" [symbols: see text] vertebrae could raise whole blood viscosity, increase degree of bloos stasis and induce or aggravate spinal disorder in further.

Objective To assess the risk factors of the in-hospital mortality of acute type A aortic dissection after operation. Method From January 2003 to June 2008,185 patients, 144 males and 41 females, with acute type A aortic dissection operated on were enrolled. The average age of patients was (49.46 ± 11.04 ) years old.The patients' demographics, history, clinical features, and some laboratory examinations were reviewed. Univariate and multivariate analysis followed by logistic regression analysis were carried out to identify the predictors of inhospital mortality. Results The in-hospital mortality rate was 9.1%. The results of univariate and multivariate analyses as follows: pre-operation positive neurological symptom (Univariate OR = 5.084,95%CI:1.792 -14.426, P = 0.002; Multivariate OR = 5.538,95%CI: 1.834 - 16.721, P = 0.002, respectively), hypotension (Univariate OR = 6.986,95%CI:1.510- 32.323,P =0.013; multivariate OR = 1.998,95%CI:0.315-12.679,P = 0.463, respectively) and renal failure (Univariate OR = 3.594,95%CI:1.237 - 10.438,P =0.019; Multivariate OR = 3.254,95%CI:1.034- 10.242, P= 0.044, respectively). Conclusions There are two predictors, pre-operation positive neurological symptom and renal failure, of pre-hospital mortality found in current analyses. Our results may improve the regimen made by cardiac surgeons and emergency doctors so as to help patients and their relatives to make correct decision.

Objective To probe the value of multi-slice spiral CT angiography (MSCTA) in decreasing surgical trauma of the cranial base meningioma. Methods Thirty-two patients with cranial base meningioma were examined preoperatively with MSCTA to observe the shape and the relationship with the adjacent vessels and the skull base. Three-dimensional images were reconstructed to imitate the approach of operation and compared with surgical findings. Meanwhile, 22 patients withnot MSCTA were selected randomly as control group. The amount of blood transfusion and the occurrence rate of complications were compared between the two groups. Results MSCTA depiceted clear three dimensional images of the meningioma and the relationship with the adjacent vessels and the skull base, corresponded very well to the surgery. By imitating the operation, all patients were designed the incision size of bone appropriately, the vessels of peritumoral were kept off effectively and the risk of the embedded vascular were assessed accurately. The conventional surgical approach and method were changed in 9 patients, 4 formulated the planning of the sub-total resection and radiotherapy preoperatively. Compared with control group, the amount of blood transfusion reduced significantly (P<0.05) and postoperative complications decreased. Conclusion MSCTA can imitate the surgical operations in multi-angle and supply the vital information for choosing the proper surgical approach, thereby reducing surgical trauma and postoperative complications.
