Objective To investigate the influence of humanistic care on patients in the operation room.Methods 80 cases of surgery patients from November 2010 to October 2011 were given humanistic care,another 80 patients before implementation of humanistic care were chosen,and the satisfaction degree of doctors and patients and recovery of patients before and after the implementation of humanistic care were compared.Results After the implementation of humanistic care,the recovery of patients improved.The total satisfaction degree of patients and doctors reached 93.2％ and 98.1％,significantly higher than those before the impIementation,which were 82.1％ and 90.2％.Conclusions Implementation of humanistic care can improve the psychological and physical state of surgery patients,and help them gain better recovery.

BACKGROUND: Preplant diagnosis and rigorous implant strategy based on multislice spiral computed tomography (MSCT) imaging can improve success rate of mini-implants as anchorage. Effective application of imaging information in implant anchorage requires reliable tools and methods.OBJECTIVE: To investigate the accuracy of the radiographic and tunnel-type surgical templates assisting implant anchorage surgery and evaluate the clinical significance.METHODS: The transparent radiographic templates were made with occlusal rest to assist MSCT to scan two pigs' skulls locatively. After designed the implant anchorage angles in MSCT images accurately, we made the tunnel-type surgical template by angle data. A total of 32 miniscrews were implanted by surgical template, and the two pigs skulls were rescanned by MSCT. After dissected the pig alveolar process, the MSCT preoperative planning angles, the MSCT postoperative measurement angles and the measurement angles of anatomic bone samples were analyzed statistically. RESULT AND CONCLUSION: The 32 miniscrews were implanted successfully. They did not damage dental roots or surrounding important structures. Compared MSCT preoperative planning angles with MSCT postoperative measurement angles and anatomic bone samples measurement angles, there were no significant differences on axial sections or cross-sections and the r concordance correlations were very good. Results show that the radiographic and the tunnel-type surgical templates are accurate and reliable for operation and will help to improve the success rate of implant anchorage.

Objective To investigate the correlation value between the impression depth of umbilical cord around neck and the blood flow indexes of middle cerebral artery (MCA) and umbilical artery (UA) in fetus.Methods Totally 139 late pregnancy fetuses of umbilical cord around neck and 28 normal fetuses were enrolled in the study.The systolic maximum velocity/diastolic minimum velocity (S/D),resistence index (RI),pulsatility index (PI) of MCA and UA in fetuses were measured by Doppler ultrasound,and the correlation of the pressure trace depth with MCA and UA blood flow parameters were analyzed.Results The pressure trace depth of umbilical cord around neck and the S/D,RI,PI of MCA were positively correlated (one round of umbilical cord around neck,r=0.32,0.32,0.35,two or more rounds of umbilical cord around neck,r=0.71,0.69,0.53,all P＜0.05).The pressure trace depth of umbilical cord around neck and the S/D,RI,PI of UA had no correlation.Compared with normal fetuses,the parameters of UA had no significant differences in fetuses with umbilical cord around neck (all P＞0.05).The S/D,RI,PI of MCA in fetuses with pressure trace depth ≥0.80 cm and fetuses with two or more rounds of umbilical cord around neck were higher than those of normal fetuses (all P＜0.05).Fetuses with two or more rounds of umbilical cord around neck had obviously increased cesarean rate compared with normal fetuses.Compared with normal fetuses,the fetuses with pressure trace depth ≥0.80 cm had increased abnormal fetal heart rate,prolonged labor time during the second stage (all P＜0.05).Conclusion In late pregnancy fetuses with umbilical cord around neck,the blood flow parameters of MCA are more sensitive than those of UA.The pressure trace depth ≥ 0.80 cm may lead to intrauterine fetal anoxia.

Objective To investigate the inhibition of Sophora flavescens extract on the degree of inflammatory swelling of guinea pigs'skin with eczema, observe pathological changes and explore the effects of the anti-in-flammatory action, in order to provide experimental basis for clinical treatment.Methods Eczema models of 40 guinea pigs were set up by smearing 2, 4-dinitrochlorobenzene on their napes to cause sensitization and motivating in the inside of their right ears.All guinea pigs were randomly divided into 5 groups equally,including the model com-pared group, positive control group and high, medium, low concentration groups of sophora flavescens.After eczema skin was continuously administered drugs for 14 days, the same part with equal area of the left and right ears was taken and weighed.The difference between the left and right ears was used to evaluate the swelling degree of skin inflammation.The pathological changes were observed by making pathological slices with HE staining with the tissue blocks of right ears.Results Compared with the model group, the swelling degree of skin inflammation was significantly relieved and dermal edema and inflammatory cell infiltrating were significantly improved in the high and medi-um concentration groups of sophora flavescens (p<0.05).Compared with the positive group, the swelling degree of skin inflammation, dermal edema and inflammatory cell infiltrating were significantly alleviated in the high concentra-tion group of sophora flavescens ( p<0.05) .Conclusion Sophora flavescens extract can effectively reduce inflam-matory response of guinea pigs'skin with eczema, having a certain significance for the clinical treatment of eczema.

Biofilm formation makes bacteria adopt a multicellular lifestyle.Compared to planktonic cells, biofilm-grown cells express an increased resistance to antimicrobial agents.Bacterial biofilm formation is a crucial step in the pathogenesis of many subacute and chronic bacterial infections.In clinical setting, biofilm can cause bacterial biofilm disease and biomaterial associated infection.Understanding the mechanisms involved in biofilm-associated antimicrobial resistance is key to the development of new solutions.

ObjectiveTo analyze the significance of serum hyper sensitivity C-reactive protein (hs-CRP),lipoprotein (a) [ Lp(a) ] and total cholesterol (TC)/high density lipoprotein cholesterol ( HDL-C )in coronary heart disease.Methods From September 2010 to September 2011,the levels of serum hs-CRP,Lp (a) and TC/HDL-C were detected in 176 patients of coronary heart disease (coronary heart disease group ) and 60 healthy controls (control group).Coronary heart disease group included acute myocardial infarction with 56 cases,stable angina with 58 cases and unstable angina with 62 cases.ResultsThe levels of serum hs-C RP,Lp ( a ) and TC/HDL-C in coronary h cart disease group were (34.51 ± 9.65 ) mg/L,(295.16 ±104.57) mg/L and 4.23 ±0.91,while those in control group were (1.26 ±0.69) mg/L,(145.26 ±42.19)mg/L and 2.54 ± 0.57.There were significant differences between two groups (P ＜ 0.05 ).The levels of serum hs-CRP,Lp(a) and TC/HDL-C in acute myocardial infarction patients were significantly higher than those in unstable angina patients and stable angina patients (P ＜ 0.05).The levels of serum hs-CRP,Lp (a) and TC/HDL-C in unstable angina patients were significantly higher than those in stable angina patients(P ＜ 0.05).Conclusions Serum hs-CRP,Lp (a) and TC/HDL-C are significantly increased in coronary heart disease,and can reflex the severity of coronary heart disease.
