Objective To probe into a doctor-seeking medical management model for China's urban hypertension patients under medical insurance, and enhance the level and quality of medical insurance management. Methods Hypertension patients were surveyed with a structured questionnaire, and the staff at community health centers and medical insurance management centers received qualitative interview. Results The hypertension patients are found to see doctors mostly at community health centers and tertiary hospitals; complaints among hypertension patients for existing medical insurance vary with their areas, mostly targeting on complicated reimbursement procedure, high threshold of medical insurance payment and low level of reimbursement. Recommendation Experiment with the single-disease payment for hypertension, with the total prepayment in per capita and per disease; greater efforts in hypertension control in communities, with more favorable medical insurance policies for communities;elevated collaboration with medical institutions at all levels, and building and standardizing the management information network for hypertension patients.

Objective To observe the action of narcotrend monitoring for perioperative anesthesia management in donor and acceptor with living donor renal transplantation. Methods 80 pairs of receptor and donor haing electie living donor renal transplantation surgery, 28 ~ 56 years. The ASA of receptor Ⅲ ~ Ⅳ, and the donerⅠ ~ Ⅱ. The receptor and donor were randomly divided into four groups , the narcotrend monitoring receptor group (R-N), the clinical experience receptor group (R-C), the narcotrend monitoring donor group (D-N), and the clinical experience donor group (D-C). Record the vital signs, the last time of anesthesia induction, operation , extract the endotracheal catheter , and the observation time in post anesthesia care unit , the dosage of propofol and dopamine, the adverse reaction, and postoperative visual analogue scale. Results The dosage of propofol in R-N group is less then the R-C group (P < 0.05). The time of extract the endotracheal catheter,and the observation time in post anesthesia care unit in R-N group was shorter then the R-C group (P < 0.05). No statistical differences between the D-N group and D-C group. Conclusions Narcotrend monitoring can significantly reduce the dosage of propofol , the observation time in post anesthesia care unit , and the postoperative adverse reactions. But there is little effect to the donor.

Objective To evaluate the reliability of mannitol for fluid responsiveness test in the patients undergoing intracranial surgery.Methods Sixty-two ASA physical status Ⅰ or Ⅱ patients,aged 18-64 yr,with body mass index of 18-25 kg/m2,scheduled for elective intracranial surgery,were enrolled in the study.The patients were mechanically ventilated after induction of anesthesia.The radial artery and central vein were cannulated,and FloTracTM/VigileoTM system was connected for stroke volume variation monitoring.Before infusion of mannitol,effective circulating blood volume was confirmed according to stroke volume variation.20％ mannitol 250 ml was infused over 20 min starting from onset of craniotomy.The fluid responsiveness test was recorded at the end of mannitol infusion.Results The sensitivity of fluid responsiveness test was 43％,and the specificity of fluid responsiveness test was 44％.Conclusion Mannitol can not be used for fluid responsiveness test in the patients undergoing intracranial surgery.

Objective To analyze the topological characteristics of the brain structural network in primary angle-closure glaucoma (PACG) patients by applying graph theoretical approaches.Methods From October 2015 to April 2017, nineteen PACG patients and nineteen gender-and age-matched healthy controls (HCs) were enrolled to undergo MRI scan. The whole brain was parceled into 90 regions by automated anatomical labeling template, and the brain structural network was constructed by the fiber distribution of continuous tracking method.Both the weighted and unweighted network analyses were performed.The global and regional properties were computed by graph theoretical analysis.To compare the brain network regional properties between two groups, two-sample t-test was utilized.The correlations between the brain structural network properties and clinical parameters were further analysed. Results Both two groups were found to follow the efficient small-world characteristics. Compared to HCs, the brain structural network in PACG patients showed no statistical significance in the small-worldness, average shortest path, clustering coefficient, global efficiency and local efficiency(P＞0.05). Compared to the HCs, the PACG patients showed decreased nodal efficiency in the right superior frontal gyrus, right inferior frontal gyrus, left median cingulate and paracingulate gyri, left amygdala and left cuneus(P＜0.05). Compared to HCs, the PACG patients showed decreased node degree in left superior frontal gyrus, medial orbital, right inferior frontal gyrus, left amygdala, left cuneus and left lingual gyrus(P＜0.05). Compared with the hub regions in healthy controls'network, we found that two hub regions disappeared.Those hubs were right inferior parietal lobule and left middle temporal gyrus. Node degree in left amygdala showed negatively correlated with visual ability (r=-0.679, P=0.001). Node degree in left lingual gyrus showed negatively correlated with vertical CDR(r=-0.791, P=0.001),which showed positively correlated with visual acuity(r=0.538, P=0.018).Conclusions The brain structural network in PACG patients showed small-worldness properties as HCs group. The alterations of local properties in visual, emotion-cognition brain regions were observed, manifesting that PACG can affect the topology properties of the structural brain network.

Objective: To determine whether microtubule-associated protein 2 (MAP2) and microtubule-associated protein 1B (MAP1B) could be prognostic biomarkers for patients with pancreatic neuroendocrine tumors (PNETs). Methods:With immunohisto-chemical staining, the expressions of MAP2 and MAP1B were examined in 193 and 120 primary tumors and peritumoral tissues, re-spectively. Then, the relationship between the expression of each protein and clinicopathological characteristics, including prognosis was analyzed. Results:MAP2 and MAP1B were expressed in 88 of 193 (45.6%) and 77 of 120 (64.2%) tumors, respectively. The expres-sion of MAP2 was significantly associated with the favorable overall survival of patients with PNETs (P=0.012). Moreover, MAP2 expres-sion was associated with the improved overall survival in a subset of patients with stageⅡand stageⅢtumors (P=0.017). The MAP1B expression did not correlate with other clinicopathological features and prognosis. Conclusion:MAP2 could be a novel, independent prognostcbiomarker for PNETs.
