Outpatient care services are usually the patient's first contact between the patients and the most bas-ic health care. The provision of outpatient care contributes to immediate and large gains in health status. The pay-ment method is one of the most common incentive methods applied by purchasers to guide the performance of outpa-tient care providers. This systematic review applied cochrane review method, and searched, screened, assessed and synthesized the relevant original studies. 19 studies were finally included. It was found that existing payment methods combined with P4 P interventions could probably slightly improved the health professionals' use of some tests and treat-ments ( adjusted RR median = 1 . 095 , range 1 . 01 to 1 . 17 ) , but may have led to little or no difference in patients' utilisation of health services ( adjusted RR median = 1 . 01 , range 0 . 96 to 1 . 15 ) and may have led to little or no difference in the control of blood pressure or cholesterol ( adjusted RR = 1 . 01 , range 0 . 98 to 1 . 04 ) . Pay for per-formance involves a complex design, each detail design may contain different incentive effect, therefore policy makers intend to apply pay-for-performance to guide the behavior of health providers, the design on each components of pay for performance should be analyzed in order to find more potential intervention points.

The amino acid sequences of the NP,P, M, F,HN and L proteins of the paramyxovirus Tianjin strain were analyzed by using the bioinformatics methods. Phylogenetic analysis based on 6 structural proteins among the Tianjin strain and 25 paramyxoviruses showed that the Tianjin strain belonged to the genus Respirovirus, in the subfamily Paramyxovirinae, and was most closely related to Sendal virus (SeV). Phylogenetic analysis with 14 known SeVs showed that Tianjin strain represented a new evolutionary lineage. Similarities comparisons indicated that Tianjin strain P protein was poorly conserved, sharing only 78.7%-91.9% amino acid identity with the known SeVs, while the L protein was the most conserved, having 96.0%-98.0% amino acid identity with the known SeVs. Alignments of amino acid sequences of 6 structural proteins clearly showed that Tianjin strain possessed many unique amino acid substitutions in their protein sequences, 15 in NP, 29 in P, 6 in M, 13 in F, 18 in HN, and 29 in L. These results revealed that Tianjin strain was most likely a new genotype of SeV. The presence of unique amino acid substitutions suggests that Tianjin strain maybe has a significant difference in biological, pathological, immunological, or epidemiological characteristics from the known SeVs.

Purpose:To evaluate the role of multi - detector row CT(MDCT) using reconstruction techniques in the assessment of patients with obstructed diseases of biliary tract.Materials and Methods: 47 Patients with obstructed diseases of biliary tract confirmed clinically underwent MDCT and their reconstructed images of biliary tract including multi-planar reconstruction (MPR) images and curved planar reconstruction(CPR) images were compared with those of 50 patients without obstruction and dilatation of biliary tract.The display effect of biliary duct structure and biliary duct wall and the display ability of biliary tract by MPR and CPR images between the 2 groups were compared and analysed.The reconstruction images of biliary tract were analysed retrospectively to evaluate the location and possible causes of biliary obstruction.Results: The display effect of biliary duct structure and biliary duct wall in MPR and CPR images of the group with biliary obstruction is better than that of control group,and the display ability of biliary tract in CPR images of the group with biliary obstruction is also better than that of control group.The accuracy of localization and cause evaluation of obstruction by MPR and CPR images is 100% and 89.4% respectively.Conclusions: The MPR and CPR images of MDCT provide a good display of biliary duct structure,biliary duct wall and an accurate evaluation of obstruction localization.The reconstruction technique of MDCT such as MPR and CPR should be widely applied in the evaluation of biliary obstruction.

Objective To investigate the clinical feactures of patients with numerous dilated Virchow-Robin space in basal gangalia.Methods Eight patients with cribriform state in striatum in brain MRI at Peking Union Medical College Hospital from March 2013 to October 2013 were enrolled.The clinical data including age,gender,common vascular risk factors and clinical manifestations were analyzed.Cognitive functions,balance and gait disturbance,as well as activity of daily living were assessed.Results All of the eight patients are male,aged from 69 to 80.All the patients had a history of hyperlipidemia,while 7 of them had hypertension.The primary complaint was either gradual motor function decline or memory impairments (3/8),or dizziness (1/8).The other 4 of them were diagnosed as stroke or transient ischemic attack.Among the 8 patients,four had mild deterioration in activity of daily living function (Barthel index 65-85).Cognitive impairment was common (8/8,the Montreal Cognitive Assessment scores 19-27),while word recall was the mostly affected cognitive domain (8/8).Gait and balance dysfunction were found in three patients (3/8,Tinetti scores ≤ 24).Conclusions Man is more likely to have predisposition to cribriform state in striatum.Mild cognitive impairments and gait abnormality are common clinical manifestations of the disease.

Objective To investigate current situation of prescription of traditional Chinese medicine (TCM) for acute stroke patients.Methods From June 2008 to October 2010,with simple cluster sampling,48 centers were randomly assigned to the intervention group receiving a standardized treatment strategy,and the usual care group without specific recommendations for treatment.No specific recommendations or restrictions of TCM were proposed for both groups.Consecutive hospitalized patients with acute ischemic stroke were recruited in this study.Clinical data and treatment strategy (including TCM) were recorded by trained investigators.The prescription of TCM three months prior to admission and at discharge was recorded and analyzed.The chi-square test was used for analysis of qualitative data.Results Totally 3 664 patients were included in the analysis (1 709 patients in standard care group and 1 955 patients in the usual care group) with male to female ratio 2∶ 1.The difference of distribution of age,sex and education level between the two groups was not statistically significant.One hundred and eighty-seven patients (5.10％) had taken TCM three months prior to admission,81.28％ of them only taking one type of TCM,without significant difference between the two groups.The percentage of patients taking TCM at discharge was significantly increased to 30.65％ for all the patients with higher percentage (38.16％) in the usual care group than that in the standard care group (22.06％).The percentage of using more than one type of TCM was also higher in the usual care group (x2 =141.43,P ＜ 0.01).Totally,112 types of TCM were prescribed at discharge.Conclusions Nearly one third of hospitalized patients with acute stroke were prescribed TCM at discharge,with mostly monotherapy and a great variety.

Paramyxovirus Tianjin strain, a new genotype of Sendal virus, was isolated from the lungs of common cotton-eared marmoset that died of severe respiratory infection in the marmoset colonies. The 19.28% IgM positive rate in the young children with acute respiratory tract infection suggested a close relationship between Tianjin strain and humans. Hemagglutinin-neuraminidase (HN) is its major transmembrane glycoprotein responsible for viral attachment, penetration and release. To clear the relationship between HN structure and function of paramyxovirus Tianjin strain, rHN1, rHN2 and rHN3 overlapping the ectodomain of HN protein were expressed. Their antigenicity and hemaglutination activity, as well as cross reactivity to standard antisera against influenza virus type A, type B were analyzed. The results indicated expressed rHNs have the natural antigenicity.The segment rHN2 possesses more linear epitopes exposed on the surface of the native I-IN protein than found in segments rHN3 and rHN1. The hemagglutination activity of segment rHN3 is higher than that of segments rHN2 and rHN1, and partially dependent on the three-dimensional conformation of HN3 protein. Cross-reactivity between rHNs and standard antisera against influenza virus type A, type B suggested that rHNs might not be the best alternative as specific antigens to detect virus in clinicalserum specimens.
