This study analyzed the genetic evolution of neuraminidases (NAs) of influenza A subtype N9 viruses with the aim of determining the genetic origin of the novel avian A/H7N9 influenza virus. The NA sequences of influenza A subtype N9 viruses available from NCBI were used to construct a phylogenetic tree using the programs ClustalX 2.0 and MEGA 6.0. This analysis indicated that the novel avian A/H7N9 influenza virus is located in the modern Eurasian phylogenetic cluster. This cluster was then further analyzed by estimating the overall rate of evolutionary change and the selective pressure at the nucleotide level using the program BEAST 2.1.2 and the web interface Datamonkey, and by generating an amino acid sequence entropy plot using Bioedit software. In this cluster, the mean rate of nucleotide substitutions in NA was found to be 3.8354 x 10(-3) and the mean ratio of non-synonymous (dN) to synonymous (dS) substitutions per site (dN/dS) was 0.140413. A particularly high level of amino acid mutation entropy was identified at nucleotides 16, 19, 40, 53, 81, 84, 112, 256, 335, 359, and 401. This genetic evolution analysis suggests that the nucleotide substitutions that characterize the novel avian A/H7N9 influenza virus neuraminidase are likely to result from the overall genetic evolution of influenza A subtype N9 virus NAs, and not from selective stress. Phylogenetic analysis suggests that the influenza A virus (A/duck/Siberia/700/1996(H11N9)) isolated in 1996 appears to be the common ancestor of the more recent influenza A subtype N9 viruses NAs.

Objective:To investigate the epidemic features of allergic rhinitis(AR)and correlative risk factors in Shihezi city,Xinjiang province,China. Method:A question-naire survey on AR and airway diseases was conducted among 2300 elementry school children in 12 schools,aged from 9 to 10 years old,from july 10 to 25,2008. in Shihezi city,Xinjiang province.Suspects of AR was identified by the survey,then they were recommended to specialist examinations for accurate diagnosis. Allergen skin tests were peformed to explore the allergenic varieties of allergic rhinitis. Diagnosis criteria of AR were that of ARIA(Allergic rhinitis and its impact on asthma). Resuit:Two thousand two hundred and eleven questionnaires were returned. The response rate was 96.1% and 2205 questionnaires were available.The prevalence rate of AR in children aged from 9 to 10 was 12.56%(277/2205) in Shihezi city.The difference of prevalence between female 13.76%(153/1112) and male 11.34%(124/1093) was insignificant statistically(χ~2=2.924,P＞0.05). The positive rate of the allergen skin test was 65.3%. The most common allergen of allergic rhinitis were plants of the mugwort and house dust mite. According to the ciassification criteria of ARIA in 2001,of 155 children suffered from intermittent AR,112 cases were mild and 43 cases were moderate-severe,while 122 suffered from persistent AR,110 cases were mild and 12 cases were moderatesevere. 5.4%(15/277) patients with AR also had bronchial asthma.25.3%(70/277) of the children with AR had inherent predisposition.Conclusion:The prevalence rate of AR in children aged from 9 to 10 in Shihezi city is 12.56%. Strategy of prevention and treatment of AR can be worked out according to the epidemical feature of AR.

The purpose of this study was to evaluate the value of Chinese herbal fumigation in the postoperative anal disease. The authors randomly divided 348 patients into treatment group and control group with 174 cases in each group. The treatment group was given to the Chinese herbal medicine hemorrhoids lotion for fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The control group was given to 1 000 mL 1: 5 000 potassium permanganate solution for sitz bath, fumigation based on conventional anti infective therapy, routine dressing change and relaxing bowel. The pain score, edema score, bleeding score, granulation tissue growth score and wound healing time of two groups were compared after operation. The results showed that the postoperative 6 h pain scores were higher in the two groups, the postoperative 3,5,7 d pain scores gradually decreased, the difference was statistically significant (P < 0.05). The difference of postoperative 6 h pain scores was no significant difference between the two groups, while postoperative 3,5,7 d pain scores in the treatment group were significantly lower than those in the control group (P < 0.05). 7 days after operation, anal margin of edema score and blood in the stool score in the treatment group were lower than those in control group, meat medicine growth score was higher than that of the control group, the difference had statistical meaning (P < 0.05). The healing time of two groups was respectively (13.89 + 2.78), (18.45 + 1.65) d (P < 0.05). This study suggested that Chinese herbal fumigation and washing could reduce the pain degree of patients, the anal margin of edema, and the blood in the stool, also could promote granulation tissue growth and shorten the time of wound healing, deserve the clinical expansion.

AlM:To explore the suitable conditions in rapid model of corneal neovascularization ( CNV ) after thermal burn under different constant temperature in rabbit.
METHODS: Total 45 New Zealand white rabbits were divided randomly into five groups ( A, B, C, D, E ) . A groups:100℃ ( n = 10 ) , B groups: 200℃ ( n = 10 ) , C groups:300℃ ( n=10 ) , D groups: 400℃ ( n=10 ) , and E groups:control group ( n=5 ) . All left eyes of rabbits in A,B,C,D groups were induced corneal neovascularization by constant temperature burning device. The growth of CNV was observed by slit lamp microscope and the area of CNV were recorded on 4 th , 7 th , 14 th , 30 th days postoperatively. SPSS 19. 0 statistical package was used for data analysis, and the data was recorded by mean ± standard deviation. Comparison by analysis of variance was made by repeated measures in the area of neovascularization at each time point in groups. Statistical tests were considered significantly when P values were less than 0. 05.
RESULTS:On postoperative 4 th , 7 th , 14 th , 30 th days: no neovascularization was found after corneal thermal burn in A group, but only a few nebula left (n=2);the area of CNV were (9.16±1.45)mm2, (37.73±5.49)mm2, (62.44± 7. 54 ) mm2 , ( 40. 28 ± 7. 39 ) mm2 in B group respectively;and (11.45±1.04)mm2, (44.51±4.64)mm2, (66.13±4.13)mm2, (43.04±2.33)mm2 in C group respectively; and (13.23± 0.86)mm2,(47.26±4.59)mm2,(67.57±4.56)mm2,(45.59± 4. 44 ) mm2 in D group respectively, and part corneal carbide ( n = 4 ) was observed as well as corneal perforation ( n= 6 ) were found on 3d in D group. No neovascularization was found in normal control group. Comparison of the areas of CNV at each time point between groups was statistically different, P < 0. 05. Statistical differences were found among B, C, D groups, P<0. 05.
COCLUSlON:ln 4 to 7d, the higher the temperature is, the more the neovascularization area of CNV are. lt has no significant difference in 14 to 30d. But corneal carbide and corneal perforation are often found in 400℃ group, so its modeling failure rate is high. lt is between 200℃ and 300℃ that repeatability and uniformity of the corneal neovascularization model of rabbit are superior.

Diabetic retinopathy (DR) is a sight-threatening chronic complication of diabetes mellitus and is the leading cause of acquired blindness in adults. Long-term exposure to the hyperglycemia of diabetes patients leads to the development of DR. Several studies have provided evidence that good diabetes control is important to prevent DR. However, emerging evidence suggests that genes are a significant contributor to an individual's risk of retinopathy. This evidence is from evaluations of familial aggregation and different incidence of DR in racial and ethnic groups. Some groups of patients develop DR despite good control and some escape retinopathy despite poor control. This suggests that the genes are involved in the susceptibility to DR. Genes suggested as having a role include those encoding aldose reductase, nitric oxide synthase, receptor for advanced glycation end products, angiotensin converting enzyme, vascular endothelial growth factors and pigment epithelium-derived factor. An understanding of the role of susceptibility genes will ultimately allow the development of novel therapeutic strategies. This article reviews the role of genetic factors in the etiology and progression of DR.
