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.

OBJECTIVE:To provide new identification method for processed medicinal material Chinese polyphaga(Eupolyph-aga sinensis,Steleophaga plancyi) and their adulterants by establishing molecular identification method based on Cytb genes. METHODS:The total DNA of Chinese polyphaga and their adulterants was extracted using modified saturation sodium chloride method. The Cytb genes of all samples were amplified with PCR using general primers REVCB2H and REVCBJ. The phylogenetic tree of all samples was constructed with Neighbor-Joining(NJ)method using MEGA 5.1 software. The sequences of the Cytb gene of all sampled were compared by using DNAMAN sofetware. The difference between genuine product and their adulterants were analyzed,and the specific primers Esin-F and Esin-R were designed for molecular identification in different regions. RESULTS:DNA extracted from processed medicinal insects was successful to amplify Cytb gene segments. The phylogenetic tree of all sam-ples was consistent with their genetic relationship. A fragment was amplified only from genuine product but not from other adulter-ants with the designed specific primers Esin-F and Esin-R. CONCLUSIONS:DNA extraction method from processed Chinese polyphaga and their adulterants have been established. Designed specific primers are highly specific to genuine product Chinese polyphaga,and can be used for the identification of Chinese polyphaga and their adulterants.

Objective Using transcranial Doppler (TCD) to evaluate the effect of selective shunt (SS) during carotid endarterectomy (CEA). Methods TCD was used for intraoperative bilateral middle cerebral artery (MCA) cerebral blood flow continuous monitoring in 169 patients with carotid stenosis treated with CEA. The patients were divided into shunt (n =32)and non-shunt (n = 137) groups according to whether they performed shunt or not. The open approaches of anterior collateral circulation were recorded. The peak systolic velocity (PSV),mean velocity (MV), pulsatility index (PI), and ratio of MV in bilateral MCA were compared after anesthesia, before and after carotid artery occlusion, before and after shunt, and after carotid artery open. Results MV before carotid artery occlusion in the shunt and non-shunt groups were 34.73 ± 13.54 cm/sand 35.32 ± 13.18 cm/s, respectively, and there was no significant difference (P = 0. 825). MV in the shunt group after carotid artery occlusion was significantly decreased in the non-shunt group (P =0. 000). The mean decline rate of MCA MV was 69.34% ± 20. 93%, and it was decreased more significantly than that in the non-shunt group (P=0. 000). The decline rate of MCA MV was increased significantly after shunt operation, the average increase was 35.68 ± 16.69 cm/s (P=0. 000). Conclusions TCD can objectively evaluate the hemodynamic changes before and after shunt operation.

Objective To explore the empathy deficits of adolescents with different types of conduct disorder. Methods The participants included 65 adolescents ( who met the DSM-Ⅳ criteria for conduct disorder)ranging from 13 ～ 18 in age,and 195 normal adolescents ranging from 13 ～ 18 in age. All participants were assessed by revised Basic Empathy Scale. 65 patients were divided into 4 subgroups according to symptoms: destructive-nondestructive subgroups and overt-covert subgroups. Results (1) Scores of cognitive empathy were lower in patients than normal controls ( (29.86 ± 4.72) vs ( 32.09 ± 4.94), P ＜ 0. 01 ). (2) There were significant differences in the levels of cognitive empathy between patients and controls (P＜0. 01 ). Scores of cognitive empathy were lower in destructive subgroup than controls ( (29.76 ± 4.46) vs ( 32.09 ± 4.94) , P ＜ 0.01 ). (3) There were significant differences in the levels of two dimensions and total scores of empathy between patients and controls (F=3.10 ～5.36, P ＜ 0.05 ). Scores of cognitive empathy were lower in overt subgroup ( 29.22 ± 3.77 ) and covert subgroup (30.21 ± 5.17 ) than controls (32.09 ± 4.94) (P＜ 0.05, P＜0.01 );and scores of affective empathy were lower in overt subgroup than covert subgroup ( (26.13 ±5.05) vs (29.50 ±4.16), P＜0.05 ). Total scores of empathy were lower in overt subgroup (55.35 ±7.09) than covert subgroup (59.71 ±7.58) and controls (60.04 ±8.50 ) (P＜0.05). (4) Logistic regression analysis showed that cognitive empathy was a protective factor for conduct disorders( OR = 0.43 ). Conclusion The cognitive empathy level of patients is significantly lower than normal students;and boys with different types of conduct disorder possess different empathic abilities when compared with healthy controls;and cognitive empathy is a protective factor for conduct disorder.

In order to solve the problem of selection and in vivo delivery problem in siRNA treatment, hepatitis B virus (HBV) HBx gene which could be targeted by siRNA was studied. The siRNA expression plasmid which specific inhibits HBx expression was obtained by in vitro selection via a dual-luciferase plasmid including HBx-Fluc fusion protein expression domain. The selected siRNA expression plasmid was then encapsulated in PEG-modified cationic liposome, which was devoted into pharmacodynamic studies at both cellular and animal level. The results illustrated that the cationic liposome which encapsulated siRNA expression plasmid could effectively inhibit HBx gene expression both in vitro and in vivo.

Objective To analyze the correlation of characteristics of carotid artery structure and the incidence of residual stenosis after carotid artery stent (CAS) placement and its influencing factors using color Doppler flow imaging (CDFI).Methods Five hundred and ninety-six cases from January 2013 to December 2015 who underwent CAS (600 pieces of stent) were included in this study.All patients were examined by CDFI within 1 month before and 1 week after carotid artery stenting.The incidence of residual stenosis was analysed.The correlation of residual stenosis and the characteristics of carotid artery lesions and atherosclerotic plaque before stenting were analyzed respectively.Results There was positive correlation between the incidence rates of residual stenosis and irregularly shaped plaque (odd ratios,9.02;95% confidence interval,5.21-15.59,P<0.05),the plaques with calcification in the surface(odd ratios,2.55;95% confidence interval,1.45-4.49,P<0.05),the residual diameter of carotid stenosis less than 1.0 mm(odd ratios,1.61;95% confidence interval,1.06-2.45,P<0.05),which were the independent risk factors for influencing residual stenosis after CAS.Conclusions Choosing a more adaptable stent based on the characteristics of carotid artery lesions and atherosclerotic plaque by CDFI before stenting may be useful for the patients to get best result of revascularization.The rate of residual stenosis may be decreased.

Objective To investigate the protective effect of inhibition of hypoxia inducible factor－1 alpha (HIF－1α) and activation of Wnt signaling pathway on brain injury in neonatal rats.Method A total of 312 newborn SD rats were used to establish cerebral white matter damage model (WMD) on day 3.And they were randomly assigned into the model group (WMD group), post－modeling HIF－1αdecomposition inhibition group (PHI group), and post－modeling HIF－1αdecomposition inhibition with activation of Wnt signaling pathway group (PHI+activated Wnt group ) and post－modeling HIF－1αdecomposition inhibition with inhibition of the Wnt signaling pathway group (PHI+inhibition Wnt group).Brain tissues were taken on day 1, 3, 7 and 14 after modeling, respectively.The changes of oligodendrocyte precursor cell (OPC) and oligodendrocyte ( OL ) in brain tissues at different time points were observed by tissue immunofluorescence.The expression of HIF－1αprotein in the brain tissue of each time point was measured by western blot technique.The mRNA level of HIF－1αand Wnt7a in the brain tissue of each time point was detected by RT－qPCR technique.Behaviors of rats were tested by the suspension experiment , the open field experiment and the dark experiment , at 28 d after modeling.Result The numbers of OPC on 1 d and 3 d after modeling and the number of OL on 7 d and 14 d after modeling in PHI +activated Wnt group were significantly higher than the other three groups.The content of HIF－1αin WMD group was the least on 1, 3, 7 and 14 d, but the content of PHI+activated Wnt group was the highest , and the difference was statistically significant (P＜0.05).On 1, 3, 7 and 14 d after modeling, the expression level of HIF－1αand Wnt7a in PHI+activated Wnt group were higher than those in the other three groups , the difference was statistically significant (P＜0.05), and Wnt7a expression was positively correlated with the change of HIF－1α(P＜0.05).There was no significant difference of suspension experiment at 28 d after modeling between groups. Compared with other groups , WMD group had the lowest score on open field experiment ( P＜0.05).The PHI+activation Wnt group had better memory function , and then the PHI group , WMD group.The latent time of dark experiment were significantly shorter in PHI +acitivation Wnt group.There were more mistaken time of dark experiment in WMD group compared with PHI +activation Wnt group.Conclusion Inhibition of HIF－1αdecomposition and activation of Wnt signaling pathway have partially repair effect on brain injury in neonatal rats.
