Objective: To compare the effects of engine-driven rotar y nickel-titanium(ni-ti) file and stainless steel hand K-file (ss-K-file) in posterior teeth’s root canal preparation. Methods: 118 root c anals of 45 cases were instrumented with ni-ti file (ProFile)by crow-down te chnique and 127 root canals of 49 cases were treated with ss-K-file by step- back technique respectively. The incidence of pain after preparation and the res ults of obturation were observed. Results:Total pain incidence i n ni-ti file preparation group and in ss-K-file group was 20.00% and 46.94% respectively (P

Objective To investigate the effect of Zhuang medicine acupuncture on brainstem auditory evoked potential (BAEP) in patients with posterior circulation ischemic vertigo (PCIV).Methods Eighty-five PCIV patients were randomly allocated to a treatment group of 45 cases and a control group of 40 cases. The control group received conventional basic therapy and the treatment group, Zhuang medicine acupuncture in addition. The peak latencies (Pg) of BAEP waveⅠ ,Ⅰ andⅠ and the interpeak latencies (IPg) of waveⅠ-Ⅰ,Ⅰ-Ⅰ andⅠ-Ⅰ were compared between the two groups after treatment.Results There were statistically significant post-treatment differences in waveⅠ andⅠ Pg and waveⅠ-Ⅰ andⅠ-Ⅰ IPg between the treatment and control groups (P<0.05).Conclusions Zhuang medicine acupuncture plus medication is an effective way to treat PCIV. It can improve BAEP indicators in the patients.

OBJECTIVE:To establish the optimal technical condition for the extraction of volatile oil from the volatile herbs of Huoxiang zhengqi prescription with supercritical CO2 fluid(SFE-CO2).METHODS:The technical condition for the extraction of volatile oil from the volatile herbs of Huoxiang zhengqi prescription were optimized using L9(34)orthogonal design table with extraction pressure,the extraction temperature,the pressure and temperature of separator Ⅰ as factors and with the yield of the volatile oil as index.RESULTS:A highest extraction yield of volatile oil from the volatile herbs of Huoxiang zhengqi prescription was achieved(2.057%)under an optimal technical condition as follows:with extraction pressure at 25 MPa,the extraction temperature at 30 ℃,the pressure for separator Ⅰ at 9 MPa and the temperature of separator Ⅰ at 45 ℃.CONCLUSION:Extraction of volatile oil from the volatile herbs of Huoxiang zhengqi prescription by SFE-CO2 is characterized by high extraction yield,stable,pure operation,safe,and by which the biological activity of the volatile oil can be maintained,thus it is a potential extraction and separation method.

We set up the characteristic medical psychology teaching mode based on the talent training objectives for three-year clinical medical majors and the requirements of the course qualification exam.The mode includes the basic psychological and clinical psychological teaching content system based on cases and tasks.Case-based teaching and Problem-based learning were used and research report and net exam were employed as main assessment methods.Online teaching resources were explored through establishing excellent course website,medlical psychology website and psychological test web

Objective To detect fat emboli in cardiac chamber of the patients undergoing total knee arthroplasty(TKA) by transesophageal echocardiography(TEE), and to discuss the relevant clinical value.Methods Eleven female patients with 12 osteoarthritis(OA) knees were underwent TKA. According to whether using tourniquet or not,12 knees were divided into 2 groups at random:tourniquet-related group (6 knees) and control group(6 knees). Echo intensity and ultrasonic characteristics of fat emboli in cardiac chamber were studied dynamically by multiplane TEE in various periods of the whole operation. Results All of the patients were implanted knee prostheses successfully. In different periods of TKA, fat emboli appeared as isoechoic or hyperechoic particles, which were found in right atrium, but nothing could be found in left heart. The imaging of the particles was flowing with duration time of 10～600s, like dots, lines, "moving star" or "shower". While femur expanding(0～3mins),the particles in right atrium and ventricle became more and more, and the echo intensity became significantly higher than those in other periods. After releasing tourniquet(0～5mins),most particles with highest echo intensity were observed in right heart,showing like "snowstorm" in tourniquet-related group, and more emboli were still detected at the end of monitoring (10 min after releasing tourniquet) by TEE,compared to the control group. No patient suffered from fat embolism syndrome(FES) with clinical manifestation. Conclusions Fat emboli in cardiac chamber can be observed sensitively by real-time TEE dynamically during TKA. It should be encouraged and promoted to analyze ultrasonic characteristics to facilitate the early detection, early diagnosis and early clinical intervention for the subclinical type of FES.

The functional experimental teaching reform plays a very important role in raising the teaching resources,consummating the experimental teaching management system,enhancing the student to practice the ability and so on and has obtained the good effect.But it also faces some problems waiting urgently to be solved and further perfected,to which this article has made the analysis and the discussion from the management science angle.The goal lies in deepening the educational reform in functional experiment unceasingly to provide the model.

ObjectivesTo investigate the effect of pediatric trauma life support (PTLS) curriculum on the improvement of rescue skill for pediatric trauma patients.MethodsPTLS course was introduced to train medical staff engaging in pediatric critical trauma care. The course included theoretical and practical part with main focus on enhancement of students’ decision on scene and rescue skill.ResultsCompared with pre-training, the students’ post-training written test scores improved signiifcant-ly, and the rates of qualiifcation and excellence were improved signiifcantly (P<0.01). All students were qualiifed for the tests of skill stations and simulation scenario. The excellence rates of the tests were as follows: ifxation and transportation 42.62%, basic and advanced airway management 81.97%, shock evaluation and management 70.49%, simulation scenario 72.13%. Both pre-training and post-training written test scores in hospital group were significantly higher than those in pre-hospital group (P<0.01).ConclusionsAfter PTLS courses, the knowledge, practice and integrated life-saving skills of students are greatly im-proved and teamwork is strengthened.

Clinical data of 53 patients (69 knees), who were treated at the Division of Joint Surgery, Department of Orthopaedics, Changzheng Hospital from January 1998 to December 2006, were retrospectively analyzed. These patients suffered from wound-healing complications following total knee arthroplasty. Wound skin problems included skin flare, disruption of wound, local hematoma, skin necrosis and deep infection. Local wound care was performed in 58 knees, debridement and secondary closure in 6 kness, and primary management of the soft tissue defect was achieved with local muscle flaps in 3 knees, with the fasciocutaneous flap in 1 knee, and with fasciocutaneous flap and skin grafting in 1 knee. Mean follow-up was 1.9 years. All wound was healed well. It is indicated that corresponding management should be used for treating wound-healing complications following total knee arthroplasty.

BACKGROUND:Postoperative acute mental disorders refer to patients without mental disorders suffer from neurological dysfunction after surgery. OBJECTIVE:To analyze the association between psychological resilience and postoperative acute mental disorders after total knee arthroplasty (TKA). METHODS:Convenience sampling, the Chinese Version of Connor and Davidson's resilience scale (CD-RISC), was used to measure the levels of psychological resilience in 832 patients undergoing TKA. The questionnaire covered three dimensions:tenacity, self-improvement and optimism. The incidence of postoperative acute mental disorders was observed after operation. RESULTS AND CONCLUSION:(1) The CD-RISC scores of the patients with TKA surgery were (57.64±10.07), lower than the average scores of the elderly community in China. 20 (2.4%) patients had postoperative acute mental disorders. (2) Pearson correlation analysis demonstrated the negative correlation between the levels ofresilience and the incidence of postoperative acute mental disorders (r=-2.43, P<0.05). (3) Patients with lower psychological resilience levels had a higher incidence of postoperative acute mental disorders. Developing psychological resilience may become an important strategy to reduce the occurrence of postoperative acute mental disorders.
