Objective To study the genetic diversity of Sinopodophyllum hexandrum so as to provide basic molecular genetic evidence for protecting and exploiting the resource of S.hexandrum.Methods Six populations of S.hexandrum were analyzed by DALP molecular markers.To make up the genetic diversity correlation data by PopGene 1.31 software and cluster by UPGMA method,and establish the dendrogram.The tree was subsequently visualized with Treeview software.Results Five primer groups were screened and a total of 150 DNA fragments were amplified,among which 104 were polymorphic,i.e.the percentage of polymorphic bands(PPB) was 69.33%,the average number of DNA polymorphic band amplified by each primer group was 20.8 and the average PPB was 14.22%.In the six populations,the total observed number of alleles(Na) was 1.693 3 and the average Na was 1.142 2;The total effective number of alleles(Ne) was 1.417 1 and the average Ne was 1.083 8;The total Nei′s gene diversity(H) was 0.244 3 and the average H was 0.048 8;The total Shannon′s information index(I) was 0.364 3 and the average I was 0.073 0;The total gene diversity(Ht) was 0.244 3 while the gene diversity within a population(Hs) was 0.048 7.The coefficient of gene differentiation(Gst) was 0.800 5 between populations,namely 80.05% genetic variation occurring between populations and the rest 19.95% within population,and estimated gene flow(Nm) was 0.124 6.Conclusion The result indicats that S.hexandrum has much larger genetic differentiation among populations and gene flow has been blocked.This might be a result of species breeding system and population habitat.

Objective To explore the prognostic value of pediatric critical illness score(PCIS)and pediatric risk of mortality score(PRISMⅢ)and the accuracy for evaluating the state of children with acute respiratory distress syndrome(ARDS).Methods Seventy-one cases hospitalized children from 29 days to 14 years old of Hebei ARDS cooperation group were selected during the 13 months between 2005 and 2006.All cases were confirmed according to ARDS diagnostic standard.For prospective studies,the patients were scored simultaneously with PCIS and PRISMⅢ at different times:when the patients entered PICU,when the patients were in the worst situation in PICU,when the patients were diagnosed as ARDS and when ARDS was serious.The data were performed by using Logistic regression etc.Results Values of Logistic regression were P

AlM:To investigate the effect of teaching mode of problem- based learning ( PBL ) in the teaching of medical students' clinical ophthalmology.
METHODS: Five classes ( total 148 students ) were randomly selected as experimental group, using PBL method, at the same time another 5 classes ( total 151 students) were also randomly selected as control group, using lecture-based learning ( LBL) mode in 2010 grade. The scores of the experimental group were compared with control at the end of term. ln addition, students and teachers were respectively interviewed using self -administered questionnaire to obtain their evaluation for PBL practice.
RESULTS:The mean scores of PBL group (78. 35±7. 63) were significantly higher than control group (71. 68±6. 37) (P<0. 001). Most of students thought that their ability of referring, synthesizing and analyzing information was enhanced by PBL, and their skills both in written and oral were also improved. PBL made it easier to understand the contexts of course. lt was the best way to improve the effect of teaching in ophthalmology based on the increase of quality in novitiate that gives more chance to students of contacting with practice, developing the ability of clinical thinking and verifying the theory in clinical novitiate. Lots of teachers considered that the classroom atmosphere was more active, students were becoming more and more proactive on their classes and the relationship between students and teachers were more harmonious when PBL was used.
CONCLUSlON:Using PBL teaching mode can highly improve the teaching effectiveness of clinical epidemiology, which is worth popularizing.

Background Proliferative vitreoretinopathy (PVR) is one of the major causes of retinal detachment surgery failure.Based on proteomic studies of PVR vitreous,the insulin-like growth factor binding protein-6 (IGFBP-6) protein was specifically expressed in the vitreous and serum of PVR patients.Furthermore,its expression level is higher in the vitreous and serum in severe PVR patients than that in mild PVR patients.Objective This experiment was to detect the expression of IGFBP-6 in a PVR rat model.Methods Seventy 7-week old male SPF Wistar rats were included and were randomized into the PVR model group and control group.A mixture of RPE-J cell suspension(5 μl) and platelet-rich plasma (5 μl) was intravitreally injected in the left eyes of adult Wistar rats to establish the PVR model,and normal saline solution was administered in the same way in the control group.The rat eyes were clinically examined 1 week,2,3 and 4 weeks after injection,and PVR was graded based on the criteria of Francine.The animals were sacrificed after 1 week,2,4 or 8 weeks for the preparation of retinal sections and liver extraction.Expression levels of IGFBP-6 mRNA in the rat retina and liver were assayed by real-time Q-PCR.The expression of IGFBP-6 protein in the rat serum and vitreous was detected by ELISA.The use of animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results Purified IGFBP-6 RNA was extracted from the liver and retina of Wistar rat and quantified by real-time Q-PCR.The expression level of IGFBP-6 mRNA in retina was (3.79± 1.33) × 10-4 in the PVR model rats,showing a significant decline in comparison with the control rats with a level of(8.32±2.96) × 10 4,4 weeks after injection (t =3.42,P＜0.01).The expression of IGFBP-6 mRNA in the 4th week was significantly lower than that of 1 week,2 or 8 weeks after the establishment of the PVR model(P＜0.05).No significant difference was found in the IGFBP-6 mRNA level in the liver between the PVR group and control group(27.60± 14.01 × 10 4 vs.25.01 ± 12.04 ×10-4,respectively),as well as among the different time points(P＞0.05).IGFBP-6 mRNA content in the retina was significantly reduced in grades 1,2 or 3 of the PVR groups compared with the control group(P＞0.05),but there was no significant difference among the different grades of PVR groups (P＞0.05).Concentrations of IGFBP-6 protein in grades 1,2 and 3 of the PVR model group were (221.00 ± 19.32),(229.63 ± 18.89) and (225.70 ± 26.71) μg/L,with a significant elevation in comparison with (173.25 ±21.11) μg/L of the control group (t =2.14,P＜0.05).However,there was no significant change among the different grades of PVR groups(t=1.24,1.46,P＞0.05).The concentrations of IGFBP-6 protein in the vitreous and serum were higher in PVR rat samples (vitreous:225.44±19.36 μg/L;serum:108.48 ± 15.78 μg/L) than in control rats (vitreous:173.25 ± 21.11 μg/L,serum:95.96 ±17.40 μg/L)(P＜0.05).Conclusions The concentrations of IGFBP-6 protein in the vitreous and serum increase in PVR rats.The results indicate that the increased IGFBP-6 in the vitreous might be a localized autocrine secretion of the eye.

AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

Objective To study the state and trends of Kesan disease in Henan province from 2004 to 2009. Methods Surveillance sites were selected: Guxian village of Luoning country from 2004 - 2007, Zuyang town of Lingbao city in 2008, and Shahe village of Lushi country in 2009. All residents of surveillance sites were examined by clinical and electrocardiogram, and suspected patients were inspected by chest X-ray to measure ardiothoracic ratio. Hair and wheat flour samples were collected and selenium levels were detected with hydride generation atomic fluorescence spectrometry. Results From 2004 to 2009, a total of 4034 people were examined.The numbers of chronic and latent KSD patients were 21 and 75 cases,respectively, and the incidence rates were 0.52%(21/4034) and 1.86%(75/4034), respectively . The number of abnormal electrocardiogram was 751 cases, and the incidence rate was 18.62%. The highest proportion of abnormal electrocardiogram was ST-T changes,accounting for 24.63%(185/751), followed by high-voltage, accounting for 18.11%(136/751), and left ventricular accounting for 13.85% (104/751). Sixty-one grain samples were collected and the wheat flour selenium level was averaged 0.034 mg/kg. Thirty hair samples were collected and the selenium median was 0.285 mg/kg. Conclusions The state of Keshan disease is in a steady state in Henna province, but higher rates of abnormal electrocardiogram is a serious problem and should be studied and prevented.

Objective To understand Kaschin-Beck disease(KBD) status in Henan Province and provide the basis for the further prevention and treatment of KBD. Methods Children aged 7 to 12 in 3 villages(Yaodian, Miaowa and Zhuyang) with the same environment such as topography, physiognomy,production mode and living habits in Shan County and Lingbao City were selected to undertake KBD clinical examination in 2008, X-ray examination of right hand and child hair samples and food samples were collected to determine the content of selenium. Selenium was determined using 2,3-Diaminonaphthalene method. Adults who were 16 years or older in 5 counties(Luoning, Lingbao, Mianchi, Shah and Lushi) were selected and examined for KBD. Results One hundred and ninty children aged 7 to 12 were clinically examined and clinical KBD were found, whereas 3 children were diagnosed as KBD by X-ray examination, the positive rate was 1.58% (3/190). All 20 521 adults were clinically examined and KBD prevelance rate was 6.10%(1251/20 521), including degree Ⅰ (3.97%,814/20 521), degree Ⅱ (1.77%, 364/20 521 ), degree Ⅲ (0.36%, 73/20 521). The average selenium contents in hair and food samples were (0.319±0.128)mg/kg and (0.031±0.009)mg/kg, respectively. Conclusions Child KBD in Henan Province is under control or almost under control, whereas the prevalence of adult KBD was relatively serious, which suggested that secondary prevention with the objective of clinically treating KBD patients should be strengthened.

Objective To investigate the effect of family supporting system on psychological emotion and quality life of leukemic children′s parents. Methods Fifty-eight parents of children with leukemia hosptalized from Juanary to December 2013 were set as control group, which received traditional education. Fifty-nine parents of children with leukemia hospitalized from Juanary to December 2014 were set as observation group which received family supporting system. The survey was done separately before intervention and 6 months after treatment by depression self rating scale (SDS), anxiety self-assessment scale (SAS) and SF-36 (the MOS 36 items short form health survey).
