Background:CT portography(CTP)permits comprehensive evaluation of portal vein and its collateral pathways. It is widely used for assessment of portal hypertension in clinical practice. Aims:To assess the value of CTP in esophagogastric varices in cirrhotic patients. Methods:A retrospective cohort study was performed in 143 cirrhotic patients admitted from Jan. 2013 to Sep. 2015 at the Affiliated Hospital of Qingdao University. All patients fulfilled the inclusion criteria and underwent CTP and gastroscopy within 7 days after admission. According to the occurrence of gastrointestinal bleeding at admission,patients were allocated into two groups:bleeding group( n = 70 ) and non-bleeding group( n = 73 ). Consistency of the results of CTP and gastroscopy was analyzed by kappa coefficient;the accuracy of CTP parameters, including diameters of main portal vein(MPV),splenic vein(SPV)and left gastric vein(LGV)for prediction of variceal bleeding was evaluated by ROC curve. Results:CTP and gastroscopy had a good consistency in typing and grading of esophagogastric varices,with the kappa value of 0. 793 and 0. 775,respectively. The diameters of MPV,SPV and LGV were significantly higher in bleeding group than in non-bleeding group(P < 0. 01),and their area under the ROC curve (AUC)in predicting variceal bleeding was 0. 741,0. 627 and 0. 816,respectively. The accuracy of diameter of LGV was superior to that of MPV and SPV. With the cutoff value of 6. 1 mm,the sensitivity and specificity of diameter of LGV were 65. 71% and 84. 93% ,respectively. With the cutoff value of 16. 3 mm,the sensitivity of diameter of MPV was 75. 71% , which was higher than that of LGV and SPV. Conclusions:CTP can be used in clinical diagnosis of esophagogastric varices in cirrhotic patients,and two CTP parameters,the diameters of LGV and MPV,might be helpful for prediction of variceal bleeding.

Objective To evaluate the effect of therapeutic communication on negative emotion and quality of life of stoke patients. Methods A total of 120 stroke patients were divided into the control group and the observation group equally. The former received routine nursing and the latter routine nursing plus therapeutic communication. After 4 weeks, they were evaluated by self-rating anxiety scale (SAS), self-rating depressive scale (SDS), trait coping style questionnaire (TCSQ) and the short-form health survey-36 (SF-36). Results After the intervention, the scores on anxiety, depression and negative coping in the observation group were lower than those in the control group (P<0.01), while the scores on positive coping and quality of life were higher in the observation group than those in control group (P<0.01). Conclusion Therapeutic communication can effectively improve stroke patients′negative emotion and quality of life.

OBJECTIVE: To evaluate the clinical value of lidocain in the treatment of tinnitus through three routes of administration (intravenous, intratympanic and acupoint injection) by analyzing literatures. METHOD: Articles were collected through Hownet, Wanfang, VIP, Pubmed, SciVerse ScienceDirect, Springer and OVID, etc. The articles were strictly evaluated based on their quality. The Meta-analysis was performed to evaluate the outcomes by RevMan 5. 2 software. RESULT: A total of 16 articles with 1203 patients were enrolled in the analysis. Their tinnitus history ranged from 7 hours to 20 years. Assessment methods include tinnitus loudness levels, severity scales and subjective feelings. None of articles refer to maintaining time, instead of "short-term", "short" and so on. A total of 133 cases received intravenous injection and the effective rate was 73.4% (98 cases). 50 cases and 332 cases received intratympanic and acupoint injection respectively and their effective rates were 74.0% and 87.7%, respectively. The effective rate ranged from 42.4% to 58.3% in control group. Meta-analysis results indicate that all three routes of lidocaine administrations are more effective than conventional methods (P < 0.05). CONCLUSION Different routes of lidocaine administration have a good but short time effects on the tinnitus control. It can effectively reduce the time of tinnitus habituation as a complementary treatment. But its value still needs further evaluation.

Photoreactive heparin was synthesized by reaction of 4-azidoaniline and heparin. An organic layer was introduced on the surface of Ti-O by 3-aminopropylphosphonic acid assembling, and then the modified heparin was immobilized on the surface by UV irradiation. Water contact angle was used to characterize the hydrophilicity, quantitive assay was done by azure staining methods, and blood compatibility was evaluated by platelet adhesion experiment. Water contact angle of heparinized surface was smaller than that of Ti-O film, which indicated more hydrophilic property of heparinized surface. The surface density of heparin increased with the prolonging of irradiation time and the density was 2.1 microg/cm2 when irradiated for 300s. It showed the heparinized surface was effective in resisting platelets from adhesion and aggregation.

OBJECTIVETo observe the impacts of electroacupuncture (EA) on microgliacytes and astrocytes of cervical spinal cord in rats with thyroid incisional pain and explore the mechanism of acupuncture anesthesia in thyroid surgery.

METHODSSixty Wistar male rats were randomized into a normal group, a model group, a Futu (LI 18) group, a Hegu (LI 4)-Neiguan (PC 6) group and a Zusanli (ST 36)-Yanglingquan (GB 34) group, 12 rats in each one. Except the normal group, a longitudinal incision, about 1.5 cm in length was done along the neck midline in the rats of the rest groups to prepare the model of thyroid incisional pain. In the Futu (LI 18) group, the Hegu (LI 4)-Neiguan (PC 6) group and the Zusanli (ST 36)-Yanglingquan (GB 34) group, after modeling for 4 h, 24 h and 48 h, EA was applied to bilateral "Futu" (LI 18), "Hegu" (LI 4) "Neiguan" (PC 6) and"Zusanli" (ST 36) "Yanglingquan" (GB 34) separately, once a day, continuously for 3 days. In the normal group and the model group, no any intervention was applied. The thermal radiant apparatus was used to detect the thermal pain threshold (PT). The fluorescence quantitative RT-PCR and the Western blotting (WB) were used to determine the expressions of protein and gene of microglia activation markers Iba1 and CD11b and the astrocyte specific protein marker, glial fibrillary acid protein (GFAP) in cervical spinal cord (Cto C) after intervention in the rats of each group.

RESULTSAfter intervention, as compared with the normal group, in the model group, the neck PT was reduced apparently (<0.05), the expressions of Iba1 and CD11b and GFAP mRNA as well as the protein expressions in the spinal cord of Cto Cwere up-regulated apparently (<0.05,<0.01). As compared with the model group, in the Futu (LI 18) and the Hegu (LI 4)-Neiguan (PC 6) group, PT was increased significantly (both<0.05) and that did not change apparently in the Zusanli (ST 36)-Yanglingquan (GB 34) group (>0.05). In the Futu (LI 18) group, the protein and gene expressions of Iba1, CD11b and GFAP were lower than those in the model group (all<0.05). In the Hegu (LI 4)-Neiguan (PC 6) group, the expressions of Iba1 mRNA, CD11b protein, GFAP mRNA and protein were all lower apparently than those in the model group (all<0.05). In the Zusanli (ST 36)-Yanglingquan (GB 34) group, the expressions of Iba1, CD11b and GFAP proteins were not different significantly as compared with the model group (all>0.05). In the Zusanli (ST 36)-Yanglingquan (GB 34) group, the expressions of Iba1 mRNA and CD11b mRNA and protein expressions in the spinal cord of Cto Cwere higher apparently than those in the Futu (LI 18) group (<0.01,<0.05); the expressions of Iba1 mRNA and CD11b protein expressions were higher than those in the Hegu (LI 4)-Neiguan (PC 6) group (all<0.05); GFAP mRNA and protein expressions were higher apparently than those in the Futu (LI 18) group and the Hegu (LI 4)-Neiguan (PC 6) group (all<0.05).

CONCLUSIONSEA at "Futu" (LI 18) or "Hegu" (LI 4), "Neiguan" (PC 6) relieves the acute neck incisional pain in the rats and its effect may be closely relevant with the down-regulation of the activities of microgliacytes and astrocytes in the spinal cords.
