The in-stent restenosis is one of the main complications in coronary artherosclerotic heart disease patients after PTCA and PCI.How to prevent it remains one of the most important projects in intervention therapy.In this paper,the preventive role of intravenous ultrasound and drug eluting stent were reviewed.

AIM To Investigate the effect of breviscapine on delayed outward potassium current in single ventricular cell of guinea pig. METHOD Using whole cell patch clamp technique. RESULTS Breviscapine enhanced I k dose dependently. Breviscapine with the concentration of 0\^01 and 0\^02 mg?L -1 increased I k by 44.6% and 78.3%,respectively. The effect could be reversed by washing. CONCLUSION Breviscapine can open the K + channel and incrase I k .

[Objective]To recommend the detailed operative skill of lower cervical transpedicle screw and peri-operative experience.[Method]From July 2004 to April 2006,based on anatomical research of cadaver,15 cases involved lower cervical had been treated by transpedicle screws and plate or rod,which assisted in fluoroscopic moniter.Lateral mass needed be revealed completely,thus basilar part of superior articular process could be recognized.The central point of screw inserted were laid on the surface of lateral mass: 5mm inner to the outside border of lateral mass;3mm below to the inferior of superior articular process.Ball-like burr was used to de-cortical.Made a pathway with 2 mm hand-drill paralleled with the upper end-plate cartilage of the vertebra and maintain abduction angle about 40?～45? with middle line of the vertebra,self-designed pedicle probe was used to ensure safety tunnel of cancellated bone.3.5 mm cortical screws were adoption and thread was not recommend.[Result]Eightysix lower cervical pedicle screws had been inserted successfully in C3～7 vertebra,exclude a failed C4 screw.Average screws length was(26 + 1.6)mm and abduction angle based on postoperative CT scan was 37.9??5.4?.Abundant bleeding was occurred while built the pedicel pathway in 2 screws,and there were 6 screws showed perforation of the pedical wall refer to postoperative CT scan. No evidence indicated the complication about injury of vessel or nerve structure.[Conclusion] The technique of lower cervical transpedicle screw are relatively safet.Successful screw insertion depends on subtile sense of operation doctor's hand.

The paper is to explore the goals and models of Orthodontic teaching in eight-year medical students. It tries to design some teaching goals, teaching models and standards of examination to train medical students according to the eight-year program characteristics, and discuss the problems of eight-year program orthodontic teaching.

Objective To develop electronic touch-screen inpatient satisfaction questionnaires so as to improve the real-fimeness and accuracy of data processing in patient satisfaction surveys and evaluations. Methods 266 inpatients from 20 clinical departments of a certain hospital in Zhangjiakou were asked to make satisfaction evaluations via a touch screen and the reliability and validity of the questionnaires were assessed by statistical and psychological means. Results The item response rate was 98.72％, the effective rate was 98.1％, and the a reliability coefficient for internal consistency was 0.9474; the composition of the questionnaires, which matched the reality of management, supported contents validity; a factor analysis showed that the factor load and structure, which matched the structure of the questionnaires, supported structure validity; intra-factor correlations, which were stronger than interfactor correlations, supported aggregation and discrimination validity. Conclusion The questionnaires, reliable andvalid, interface friendly and easy to operate, facilitate their use by patients with different backgrounds. The real-time occurrence and antomatic pooling of survey data render possible the automation of data collection in patient satisfaction surveys and evaluations.

Objective To compare the clinical efficacies of warm needling versus salt moxibustion in treating knee osteoarthritis. Methods One hundred and twenty patients with knee osteoarthritis were randomly allocated to groupsⅠ andⅡ, and control group, 40 cases each. GroupⅠ received salt moxibustion; groupⅡ, warm needling; the control group, routine medication. After 4 weeks of treatment, the Lysholm Knee Scoring Scale scores, the VAS scores, the quality of life scores and the clinical therapeutic effects were compared between the three groups.Results There were statistically significant pre-/post-treatment differences in the Lysholm Knee Scoring Scale scores, the VAS scores and the quality of life scores in the three groups (P<0.05). There were statistically significant post-treatment differences in the Lysholm Knee Scoring Scale scores and the VAS scores between groupⅠ orⅡ and the control group (P<0.05). The total efficacy rate was 90.0% in groupⅠ, 87.5% in groupⅡ and 70.0% in the control group. There was a statistically significant difference in total efficacy rate between groupⅠ orⅡ and the control group (P<0.05).Conclusions Warm needling and salt moxibustion are both effective way to treat knee osteoarthritis and have equal therapeutic effects.

OBJECTIVE To analyse the infection of Acinetobacter baumannii(ABA) in ICU of Cardiac Surgery,and make analysis for its resistance to 14 antibiotics.METHODS The collection of clinic stains of ABA isolated from ICU in 2008.The pathogens were identified by VITEK-Jr.RESULTS The drug resistance rates of Imipenem and cefoperazone/sulbactam were 74.4% and 18.6%.The resistance rates to other drugs were more than 70%.CONCLUSIONS ABA strains isolated show the trend of multi-durg resistance.We should pay more attention to the monitor of the resistance to antibiotics.

Objective To know the cognition,attitude and needs among middle-aged andaged women with urinary incontinence(UI) in communities. Methods A questionnaire survey wasconducted in 66 middle-aged and aged women with UI in two communities and the results were an-alyzed. Results Most patients lacked the knowledge of UI;UI had impact on their physical andmental heahh.Must patients wished to know about the treatment knowledge,and health education of med-ical staff was the most promising way.The mastering degree of knowledge about disease was not related tothe serious degree of disease and age,but was positively related to education degree and economic income.Conclusions We should publicize the knowledge about UI and provide health education and emotionalsupport to patients.And we should emphasize the training about UI among medical staff.

Objective To evaluate the effect on treatment of multiple myeloma complicating femoral neck fracture by surgical intervention combined with drugs.Methods Twelve patients with multiple myeloma complicating femoral neck fracture were treated by cemented total hip arthroplasty femoral head shank.All of patients were received zoledronic acid treatment,at the same time,7 cases of them treated by MPT regimen (melphalan,methylprednisolone and thalidomide),3 by bortezomib combined with dexamethasone,and 1 by autologous peripheral blood stem cell transplantation.Results Twelve patients could tolerate surgery,postoperative pain was significantly reduced.Assessed by using Harris hip function score after 6 months operation,2 cases were excellent,7 cases were good,3 cases were common,excellent and good rate was 75％ (9/12).All patients were followed up for 8 months to 3 years,1 case of local recurrence after 13 months.1-year overall survival rate was 100％,2-year overall survival rate was 83％,and 3-year overall survival rate was 67％.Conclusions Multiple myeloma complicating femoral neck fracture,using bone cement in total hip arthroplasty femoral head shank to clear the local tumor lesions,receive reconstruction capability,rapid postoperative recovery,pain relief,and opportunities for further comprehensive treatments.The bisphosphonate can promote new bone formation and prevent further fractures.The surgical intervention combined with chemotherapy could relieve the symptoms,reduce tumor cell burden,improve quality of life and prolong survival time.
