Objective To compare the effect and safety between cemented and uncemented long-stem hip arthroplasty for treatment of unstable intertrochanteric fracture in the elderly.Methods A retrospective review was made on 70 cases (70-87 years old) undergone artificial long-stem hip arthroplasty of unstable intertrochanteric fracture between June 2012 and June 2014.According to the material of prostheses,the cases were assigned to cemented group (n =36) and uncemented group (n =34).Operation-related index,postoperative complications,ambulation time,Harris hip score and prosthesis stability and excellent results were compared between the two groups.Results There were no significant differences in operation time,bleeding volume and ambulation time between the two groups (P ＞ 0.05).Postoperative drainage volume and blood transfusion volume in cemented group [(277.4 ± 22.0) ml and (245.1 ± 17.8) ml] were lower than these in uncemented group[(294.2 ± 33.7) ml and (262.8 ± 30.9)ml] (P ＜0.05).Harris scores in cemented group were higher than these in uncemented group 1 and 3 months after operation(P ＜0.05),and there were no significant differences 6 and 12 months after operation(P ＞ 0.05).Complication rate had no significant difference between the two groups (P ＞ 0.05).Two cases were died of cement poisoning,one case of subsequent acute myocardial infarction,and two cases of subsequent acute cerebral infarction.Sixty-five cases were followed up for 12-36 months,which showed no complications such as prosthesis loosening,displacement or infection.Prosthesis stability and treatment excellent rate between the two groups were not significantly different (P ＞ 0.05).Conclusions Clinical efficacy of the two treatments is comparable,including good function recovery and early off-bed activity.Cemented long-stem hip arthroplasty reduces blood requirements,but the risk of cement poisoning exists.

0.05].After 12 week treatment,the YGTSS total score in study group was significantly lower [(27.88?14.24) vs(36.53?17.45) scores] and the reduction rate of YGTSS score was significantly higher [(43.12?18.42)% vs(33.49?14.38)%] compared with those in control group(Pa

Background and purpose:Chemotherapy is the important way of breast cancer treatment, but the drug-resistance has attracted special attention. The emergence of drug resistance is closely related to the abnormal enhancement of DNA-damage repair. Both Kif4A and PARP-1 are important molecules of DNA repair. The research investigated the function of Kif4A in epirubicin up-regulating the activity of PARP-1 in breast cancer cells and possible significance. Methods:Western blot was used to detect the expression of Kif4A and PARP-1 after treatment with epirubicin in MDA-MB-231 and MCF-7 cells; the expression of PARP-1 and its activity were detected after high expression of Kif4A and treatment with epirubicin;FCM was used to detect cell apoptosis after treatment with epirubicin combined with PARP-1 inhibitor 3-ABA. Results:Epirubicin up-regulated PARP-1 activity and induced low expression of Kif4A in breast cancer cells, both of them showed dose-dependent and time-dependent. After high expression of Kif4A, the activity of PARP-1 was inhibited and the apoptosis of cells increased, epirubicin partially reversed the activity of PARP-1 inhibited by high Kif4A expression. Both of epirubicin and 3-ABA induced cell apoptosis, combination of them further increased cell apoptosis compared with alone used (P<0.05). The results also showed the apoptosis rate of MDA-MB-231 cells induced by epirubicin, PARP-1 inhibitor 3-ABA and high expression Kif4A was higher than that of MCF-7 cells (P<0.05). Conclusion:Epirubicin increases the activity of PARP-1 dependent on the low expression of Kif4A in breast cancer cells. Kif4A might become a novel target for overcoming resistance of epirubicin.

A total of 105 patients with ketosis-onset diabetes were divided into four groups (A+B-,A + B +,A - B -,A - B +) based on the results of islet-associated autoantibodies (A +,A - ) and β-cell function (B +,B - ).Nearly 94％ patients in the A -B + group and 1/10 patients in the A - B - group were non-insulin dependent.While in the A + B - and A + B + groups,the detection rates of subsequent non-insulin dependency were 20％ and 58％,respectively.Among the four groups,patients in the A - B + groups had a lower level of IL-6 and a higher level of TNF-α. Patients in the A + B - and A + B + groups had a higher level of IL-18.Our study indicates that patients with ketosis-onset diabetes may present different clinical characteristics. Evaluate the islet-associated autoantibodies and pancreatic β-cell function may be helpful to the clinical diagnostic and therapeutic strategies in diabetes.

BACKGROUND: Presently, it is a certain preventive effect of local emplacement of various isolated materials during operation and postoperatively drug-controlled inflammatory reaction on adhesion between epidural and nerve root after laminectomy.OBJECTIVE: To study the preventive effect of chitosan and titanium net on epidural cicatricle adhesion after laminectomy.DESIGN, TIME AND SETTING: Randomized controlled animal study, which was performed in Guiyang Medical College from June to December 2005.MATERIALS: Eighty adult rabbits, weighing (2.0±0.2) kg, were used to establish vertebral plate resection models. Chitosan was provided by Shanghai Qisheng Biological Agent Industry Company, and titanium net by Guizhou Kelun Pharmacology Company Limited.METHODS: Eighty adult rabbits were randomly divided into four groups, including control group (0.5 mL saline), titanium net group (titanium net in the size of 1.0 cm × 0.8 cm was covered on defect region of vertebral plate and fixed on processus spinosus of upper and lower cone, bilateral muscles and soft tissues), chitosan group (2 mL chitosan), and chitosan + titanium net group (combination of chitosan and titanium net). Six rabbits were sacrificed in the 2nd and 4th weeks postoperatively, and eight rabbits were chosen as the samples in the 8th week.MAIN OUTCOME MEASURES: Morphological changes of cicatricle.RESULTS: Cicatricle was clearer in the control group. Titanium net could relieve peripheral cicatricle of dura mater and effectively isolate peripheral cicatricial tissue and spinal dura meter. Chitosan could remarkably prevent from cicatricle adhesion and inhibit inflammatory reaction. The combination of chitosan and titanium net could effectively inhibit proliferation of cicatricle surrounding dura meter.CONCLUSION: Association of chitosan and titanium net can effectively inhibit cicatricle adhesion surrounding dura meter after laminectomy.

Objective To evaluate two kinds of anterior screw fixations in the treatment of odontoid fractures. Methods A total of 36 patients with D' Alonzo type Ⅱ odontoid process fractures were treated with anterior screw fixation in our department from 1999 to July 2009. There were 28 males and 8 females at mean age of 42.3 years (rang 17-59 years). According to time and surgery procedures, the patients were divided into Group A ( from 1999 to June 2005, n = 11 ) and Group B ( from June 2005 to July 2009, n = 25 ). Patients in Group A received anterior hollow screw fixation of the odontoid process monitored under G-arm or C-arm, while those in Group B received anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system. The operation time and blood loss in two groups were compared by Student' s t test and analyzed with SPSS 13.0 statistical software. X-ray examination was performed in all patients 3, 6 and 12 months after operation to observe fracture union and stability of the upper cervical spine. Results The operation time was ( 102 ± 12) min ( range, 77-148 min) in Group A and ( 104 ± 14) min ( range, 71-150 min) in Group B, with no statistical difference ( P =0.21 ). The blood loss was (465 ± 5) ml (range, 20-130 ml) in Group A and (42 ± 6) ml (range, 26-150 ml) inGroup B, with no statistical difference (P = 0.16). All patients received reexamination three months after operation, which showed no bony union or dislocation but average 40% restriction of neck rotation. One year after operation, 30 patients (83%) got fracture union and six ( 17% ) got fiber healing, with average 24% restriction of neck rotation. Conclusions There is no statistical significant differences between two groups in aspects of operation time, blood loss and fracture healing. But anterior screw fixation of the odontoid process assisted by Iso-C 3D navigation system can reduce exposure to radiation of both patients and surgeons. Furthermore, solid screws can be applied to augment the fixation intensity and thereby reduce the complications caused by non - union.

OBJECTIVE:To provide reference for the selection of new edition of Essential Medicine List by quantitative com-prehensive evaluation for additional essential medicine. METHODS:The evaluation factors were established according to Delphi method,and Analytic Hierarchy Process(AHP)was conducted to compare the factors in pairs,construct the judgment matrix,cal-culate the weight coefficients of every factor and do the consistency test. RESULTS:The evaluation model was composed of 6 first-class indexes(including effectiveness,safety,stability,availability,affordability and adaptability)and 24 second-class index-es,and the weight of each index to the target layer was calculated. Among them,the weight of validity and security is the top two. CONCLUSIONS:The weight coefficient can be determined scientifically and reasonably by AHP,and the reliability and operability of the evaluation index system can be improved. It is a useful attempt to explore the selection system of additional essential medi-cine.
