Grey system analysis method was used to study the correlation between water pollution in D Lake area and death rate of malignancy with death rate of malignancy as effect sequence and a variety of water pollution index as factor sequence. On the basis of grey correlation analysis, grey system predication model was established for death rate of malignancy in population in D Lake area including GM(1, N) model for death rate of malignancy [MR(t+1) = (9.9987E1 + 5.0001E2 + 10.8994E3 + 1.1114E4 + 165.1029) x e(-0.0070t) - 9.9987E1 - 5.0001E2 - 10.8994E3 - 1.1114E4] and GM(1, 1) model for related factors [E1(t+1) = 52.1214 - 46.9468e(-0.0058t), E2(t+1) = 4.6114 - 4.5664e(0.0015t), E3(t+1) = 1.1389 - 1.1212e(0.0065t), E4(t+1) = 554.5867 - 549.8006e(0.0016t)], and the trend of death rate of malignancy from 2000 to 2010 was predicted.

Objective To investigate the causes and treatment of lymphatic fistulas(LF) after radical operation of gastric cancer . Methods We observed the clinical data of 31 cases of lymphatic fistulas after the radical operation of gastric cancer , including the amount of drainage from the abdominal cavity, the levels of hemoglobin and serum albumin, post operative morbidity and the survival rate. Meanwhile, the difference in the amount of abdominal drainage before and after using octreitide was observed in LF patients. Results The rate of complications in the LF group was significantly higher than that in the non LF group(control group) (P

Objective To systematically evaluate the risk of BRCA1 mutation in patients with triplenegative breast cancer (TNBC).Methods Articles about the association between the TNBC and BRCA1 mutation were retrieved from database,such as PubMed,CNKI,Wanfang,VIP and CBM databases.The odds ratio (OR) was used to evaluate the risk of BRCA1 mutation in TNBC compared with non-TNBC.Rev Man 5.2 software was applied to perform the Meta-analysis.Results A total of 23 articles were eligible for the Meta-analysis,including 1 104 patients with TNBC and 4 245 patients with non-TNBC.The pooled OR was 7.67 and 95％ CI(6.24,9.42),and the difference was statistically significant (Z =19.38,P ＜ 0.000 01).In the subgroup analysis about the race,the pooled OR for Asian was 6.67 and 95％ CI (4.98,8.95).The pooled OR for Caucasian was 8.83 and 95％ CI (6.61,11.80).There was statistically significant difference in the pooled OR between the Asian and the Caucasian (Z =14.74,P ＜ 0.000 01).Conclusion The patients with TNBC are 7.67 times more likely to have BRCA1 mutation compared with non-TNBC phenotype.Largesample randomized controlled trials are warranted to demonstrate the detection of BRCA1 mutation can be a conven-tional application in clinical for the patients with TNBC.

Objective To inoertyate the results of the management of fracture of the proximal tibial epiphysis ,with a particu‐lar reference to the prognosis and complications in children .Methods From January 2002 to June 2012 ,a total of 19 children with fracture of the proximal tibial epiphysis were reviewed ,10 cases were treated with closed reduction and immobilization with plaster cast ,9 patients were operated upon with open reduction and internal fixation .Results All the patients were available at the final follow up with a mean of 2 .8 years (range ,2‐4 .8 years) ,The mean healing time of the fracture was 11 .8 weeks (range ,8 .5‐20 weeks) .According to the assessment system described by Lysholm ,the knee joint function of patients was 13 excellent ,4 good ,1 better and 1 poor .1 case occurred traumatic arthritis ,leading to the pain of keen ,One patient had epiphyseal plate closed early ,and one patient had genu valgum .Conclusion Open reduction and internal fixation should be recommended for the management of the facture with remarkable displacement of type Ⅰ and type Ⅱ ,or the facture involving the articular surface collapses more than 5 mm or separates more than 2 mm of type Ⅲ and type Ⅳ .The treatment with Kirschenel wires or hollow lag screw fixation could achieve good results .

Objective To study and analyze technology of proxy server,VPN and specific remote access system.Methods The application of digital medical library was studied in such four aspects as adaptability,security,accessibility and extensibility.Result Many approaches were put forward to break the limits of IP address and realize remote access to digital resources.Conclusion In order to meet the actual requirements in the remote access of digital medical library,the following rules should be observed: the technical scheme with obvious functional limitations should be avoided;importance should be laid on mutual sharing and remote access between chief library and branch library;the maximum concurrent access should be born;multiple certification methods should be utilized as well as multiple techniques such as information distributing.

Objective To observe the clinical effects of compound carraghenates cream on edema and pain after mixed hemorrhoid surgery. Methods 180 cases of patients with mixed hemorrhoids divided into the observation group and the control group, 90 cases in each group according to the random number table method. The control group was treated with Vaseline oil gauze to cover wounds after operation, and the observation group was treated with compound carraghenates cream after operation. The clinical efficacy, VAS pain score , the edema symptom scores and the pain relief time, edema symptom relief time, the wound healing time ,untoward effect were compared and observed after treatment between the two groups. Results The total effective rate of treatment in the observation group was significantly higher than that in the control group (95.56％ vs 85.56％) (P<0.05). The VAS pain scores of the observation group on the 1st day, 3rd day and 7th day after treatment were significantly lower than those of the control group (P<0.05), and the edema symptom scores on the 3rd day and 7th day after treatment were significantly lower than those of the control group (P<0.05). The time for pain relief, the time for edema relief and the wound healing time in the observation group were significantly shorter than those in the control group (P<0.05). Conclusion Compound carraghenates cream can effectively relieve edema and pain after mixed hemorrhoid surgery, and it also can shorten the course of disease and promote wound healing with safety.

Arterial thrombosis (AT) is a common disease which usually causes acute myocardial infarction,ischemic stroke and other ischemic cardiovascular and cerebrovascular diseases,which shows high rates of morbidity and mortality,and has become a serious problem to human health.It is increasingly clear that the interactions among platelets,the endothelium and leukocytes are important throughout all stages of the atherothrombotic process.It is of great significance to search for therapeutic targets in the process of AT and developing the therapeutic drugs based on those newly discovered targets.This article reviews the research advances in the discovery of antithrombotic targets and the current situation of drug development based on those antithrombotic targets found in the recent 5 years,in order to provide some references or clues for the development of innovative drugs to prevent and treat AT.

Using questionnaire of self-concept to 144 senior students,the study tries to understand the character of university students'appraisals of their social comparison,appraisals of their earlier and present selves.The result shows:For all social comparison in the past and present,university students tend to rank themselves as superior to a majority of their peers;in comparison with their earlier and present selves,there is significant difference in feature,school achievement,maturation,ambition,and self-acceptance.And present self is superior to earlier self on feature and self-acceptance,inferior to earlier self on school achievement,ambition and maturation.
