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.

Objective To explore the reasons why patients with Keshan disesse complicated with hypertension and their interaction in Fuyu County, Heilongjiang Province. Methods Fifty-three patients with Keshan disease were investigated in January, April and July in 2007. Blood pressure was measured and the risk factors of hypertension were investigated. According to the diagnostic criteria of hypertension, patients were divided into hypertension group and non-hypertension group, and then the risk factors of hypertension, as well as the course of Keshan disease, were compared between the two groups. The risk factors include age, gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity. Results The age of hypertension group[(57.83±8.89)years] was significantly higher than that of non-hypertension group [(51.53 ± 9.43)years, t = 2.3630, P < 0.05) ;while the course of Keshan disease in non-hypertension group [(31.63 ± 8.66)years] was notably longer than that in hypertension group [(25.08±11.41)years, t = 2.0224, P < 0.05] ;No statistically significant difference in gender, family history of hypertension, salt intake in diet, smoking, drinking and obesity was observed between the two groups(χ2 = 0.0072,0.1779,0.0029,0.1555,0.119,0.7679, all P > 0.05). Conclusions Age might be an important factor in patients with Keshan disease accompanied by hypertension, and the role of other risk factors of hypertension should not be overlooked;whether Keshan disease and hypertension can affect each other needs further investigation.

Objective To explore the effect of fluoride and arsenic pollution on bone metabolism in exposed population. Methods One hundred and fifty-two fluoride and arsenic exposed people were selected from Jiaole village, Yuzhang town, Xingron county, Guizhou province in 2006, and 59 not exposed people from Daguoduo village 13 km away from Jiaole village were selected as control. Urinary fluorine(UF), urinary arsenic (UAs), urinary hydroxyproline (UHYP), cross-linked N-telopeptides of type I collagen (UNTX) and bone strength index(STI) were detected. Results The main effect of fluoride on UHYP and UNTX were statistically significant (F = 9.785, 4.225, P < 0.01 ), but was not significant on STI(F = 0.183, P > 0.05). The main effect of arsenic on UNTX was statistically significant (F = 2.660, P < 0.05 ), but was not significant on UHYP and STI(F = 2.012, 0.183,all P > 0.05). The interaction between fluoride and arsenic on UNTX was statistically significant (F= 2.429, P <0.01), but was not significant on UHYP and STI(F= 1.218, 1.001, all P> 0.05). Conclusions Fluoride exposure can affect the metabolism of collagen and bone resorption, and Arsenic exposure main affect bone resorption, fluoride and arsenic co-exposure have more significant effect on bone resorption. UNTX may be used as biological biomarker of bone metabolism for population co-exposed to fluoride and arsenic in health monitoring.

?AlM: To evaluate the clinical efficacy of posterior continuous curvilinear capsulorhexis ( PCCC ) combined with anterior vitrectomy in preventing posterior capsule opacification of congenital cataract surgery.
?METHODS:Postoperative clinical follow-up data of 82 cases ( 87 eyes ) with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group ( 38 cases, 40 eyes, recieved phacoemulsification + PCCC ) and the study group ( 44 cases, 47 eyes, accepted phacoemulsification+ PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow - up. lntraoperative and postoperative complications were observed.
?RESULTS:The rate of central optic axis opaque grade 0 in control group was 37. 5%, compared to 76. 6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group (P<0. 05). The 19 eyes(47. 5%) of visual acuity testing ≤0. 5 in control group , was higher than the 7 eyes(14. 89%) of that in the study group, The 21 eyes (52. 5%) of visual acuity testing >0. 5 in control group was lower than the 40 eyes ( 85. 11%) of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up ( P<0. 05 ) , and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups ( P<0. 05), but there was no significant difference between two groups in intraocular pressure (P<0. 05).
?CONCLUSlON: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.

Objective To explore the associations between coagulation factor Ⅶ (FⅦ)polymorphisms and its haplotype with risk of ischemic cerebrovascular diseases (ICVD) in Henan Han population. Methods Five hundred and twelve cases with ICVD as patient group and 560 healthy subjects as control were recruited in the study. The polymorphisms of R353Q, 5'F7 and IVS7 were detected by PCR-RFLP. The genotype frequency and allele gene frequency were compared between ICVD group and control group. The haplotype was analyzed by SHEsis software. Results The RQ genotype frequencies and Q allele frequencies of ICVD group were significantly lower than those of control group. The distribution of H7 allele frequencies and H6H7 genotype frequencies of FⅦ/IVS7 polymorphisms had significant difference between ICVD group and control group. Finally, the prevalence of R-P0-H6 haplotype in ICVD group(53. 3% )was higher than that in control group (47.5%, OR = 1. 219, 95% CI 1. 028-1. 446,P =0.023). Conclusions In Henan Han population, the Q allele of F Ⅶ/R353Q polymorphisms and the H7 allele of F Ⅶ/IVS7 polymorphisms may be protective genetic factors against ischemic cerebrovascular disease, and the R-P0-H6 haplotype may be a risk factor of ischemic cerebrovascular disease.
