Objective To reveal the trend of change incidence of hepatitis A(HAV)in Shandong province and explore dynamic analysis methods.Method Dynamic analysis was made on data of hepatitis A in Shandong province from 1990 to 2006.Results The reported incidence of hepatitis A patients dropped from 53.97/100,000 to 1.14/100,000 in Shandong province from 1990 to 2006,which showed a marked downward trend;the groups under the age of 10 dropped from 55.60% to 5.12%,the average age of incidence moved from 14.40 years old to 40.19 years old.Conclusion The incidence of hepatitis A has been changed from prevalent to sporadic in Shandong province,and there was a further downward trend;the age of the high-risk population has been shifted to older age group;the sex ratio of incidence between males and females in the population above 10 years of age had an expansion trend,the age distribution curve differences between males and females was also expanded.

Objective To analyze the clinical features and significance of the samples which the expression of ANA is positive and the expression of anti‐ENA antibody is negative .Methods Detect ANA and anti‐ENA antibody of all the 297 samples by indi‐rect immunofluorescence method and biological chip technology ,repectively .And analyze the fluorescence karyotype of ANA posi‐tive specimens with double‐blind method .Screen the samples which anti‐ENA antibody express negative from ANA positive sam‐ples .Compare and analyze the fluorescent karyotype .Results Of all the 297 samples ,74 cases were positive for ANA ,the positive rate was 24 .9% (74/297) .The majority of patterns were speckled pattern (43 cases ,58 .1% ) ,cytoplasmic granular pattern (9 ca‐ses ,12 .2% ) ,and antibody to centromere antigen(9 cases ,12 .2% ) ,respectively .In 74 cases of ANA positive specimens ,ENA anti‐body the negative rate of ENA antibody is 17 .6% (13/74) .Of the 13 cases ,the most frequently occurred pattern was the speckled pattern(11 cases ,84 .6% ) ,the rate of cytoplasmic granular pattern and antibody to centromere antigen was 7 .7% (1/13) respec‐tively .Conclusion In the serum samples which express ANA positive and ENA antibody negative ,the rate of speckled pattern is significantly higher than the other patterns ,and far more than the rate of speckled pattern in the samples which express ENA anti‐body and ANA positive (52 .5% ) (chi‐square= 5 .018 ,P< 0 .05) ,with statistical significance .We consider the speckled pattern samples be in favour of discovering new antibodys of this kind of serum sample .

Velocity vector imaging (VVI) can quantitatively detect biomechanical characteristics of myocardium and vascular wall based on the principle of speckle tracking , getting rid of the angular dependence of tissue Doppler ima‐ging (TDI) .It can distinguish myocardial segment movements ,observe cardiac twisting motion and discover early e‐lastic changes of vascular wall and evaluate stability of atherosclerotic plaques ,which possesses important signifi‐cance for differential diagnosis of early heart and vascular diseases .The present article made a review on application progress of VVI in cardiovascular diseases .

After the importance of literature definition and the main bases to define literature were described, including its major nature一knowledge information, signals displayed in knowledge information-words,symbols,pictures, audio frequency, visual frequency, and external form of knowledge information-material media, and the solidification process of knowledge information on media-records, the different definitions of literature were analyzed with some commends, the 4 major elements of literature were summarized, namely knowledge information, media, records, and words, symbols and pictures, etc.

This paper introduced the risk communication principles made by WHO including: establishing trust, releasing information betimes, keeping transparent , listening to the public opinions and involving them in etc.Seven steps to make a two -way and interactive communication are also put up on that basis .It covers infor-ming the medial information and comforting patients ’ anxiety.In addition, the strategies of informing the patients of high-risk medical issues or low -risk medical issues and good or bad news are also mentioned .

Objective To explore the predictive value of detection of serum Cys -C and hs -CRP in cardio-vascular adverse events of patients with primary hypertension.Methods 138 patients with hypertension were selected and their serum Cys -C and hs -CRP levels were detected.Patients were given conventional treatment and blood pressure was controlled stably.Two years later,patients were divided into stable group(96 cases)and progression group(42 cases)according to the occurrence of cardiovascular adverse events,additionally,42 people received physi-cal examination in corresponding period were selected as control group.The levels of serum Cys -C and hs -CRP were detected again.The detection results and complications were analyzed retrospectively.Results For initial detec-tion,the levels of serum Cys -C[(0.87 ±0.39)mg/L,(1.16 ±0.47)mg/L]and hs -CRP[(1.79 ±0.56)mg/L, (2.26 ±0.91)mg/L]in the stable and progression groups were higher than the control group[(0.59 ±0.32)mg/L, (0.68 ±0.37)mg/L],and those in the progression group were higher than the stable group(t =2.162,3.904, 5.237,6.441,all P <0.01).For the reexamination,the levels of serum Cys -C[(1.39 ±0.41)mg/L]and hs -CRP [(3.37 ±0.89)mg/L]in the progression group were higher than the stable group[(0.92 ±0.43)mg/L,(1.83 ± 0.62)mg/L](t =2.958,5.119,all P <0.01).The levels of serum Cys -C and hs -CRP in the stable group after 2 years were similar to those at initial detection(t =0.331,0.414,all P >0.05),but the levels in the progression group increased obviously(t =2.146,3.144,all P <0.01).Conclusion The levels of serum Cys -C and hs -CRP were closely related to disease progression and prognosis.And the detection of them can predict the progression of disease,conductive to taking intervening measures for the early stage.

After the development of medical informatics and the challenges it is faced were described, the charac-teristic and differential strategies for its development were put forward, including combining electronic information technology with medical informatics practical skills and medical knowledge, training more health information profes-sionals for the society, and improving the overall health information level in our country in order to achieve the sus-tainable development of medical informatics.

Objective:To explore the curative effect and security of Jiuwei Zhenxin granules in the treatment of generalized anxiety disorder. Methods:Totally 112 patients with generalized anxiety disorder were randomly divided into the research group and the control group with 56 ones in each. The research group was given Jiuwei Zhenxin granules while the control group was given paroxetine with the treatment course of 6 weeks. The curative effect of the two groups was observed using Hamilton anxiety scale ( HAMA) , and the side effects were observed using treatment energent eymptom scale( TESS) . Results:After the 2-week treatment, HAMA scores were signifi-cantly lower than those before the treatment (P<0. 01). HAMA scores between the two groups before the treatment and at each time point after the treatment had no statistically significant differences (P>0. 05). The recovery rate and effective rate of the two groups also showed no statistically significant differences (P >0.05). The incidence of adverse drug reactions in the research group was 14. 8%, which was lower than that in the control group (22. 6%, P<0. 05). There was no statistically significant difference in TESS total score between the two groups (P>0. 05). Conclusion:Jiuwei Zhenxin granules show similar effect with paroxetine in the treat-ment of generalized anxiety disorder with lower adverse reaction incidence and promising safety.

Myeloproliferative neoplasms (MPN) are a group of diseases with malignant cloning in hematopoietic stem / progenitor cells. The main clinical feature is excessive proliferation of one or more lineage of myeloid cells, which cause increasing count of erythrocytes, granulocytes and platelets in peripheral blood.Arterio-venous thrombosis and complications are responsible for the mortality of MPN. Low molecular weight heparin (LMWH) is a kind of anticoagulant that commonly used for its safety and validity. It can improve the hyperviscosity of blood , affect platelets, and interact with leukocytes and endothelial cells, by which can reduce cells aggregation. LMWH can effectively play an active role of anticoagulant in high-platelet plasma. All of these provides a theoretical basis to its availability in MPN.
