Objective To demonstrate the clinical results of the patients with failed cemented femoral component due to aseptic loosening with extensive porous-coated femoral implants. Methods Be-tween 1998 and 2003, twenty hips (20 patients) with a failed cemented femoral component were revised us-ing extensive porous-coated femoral components and allograft. There were 12 males and 8 females. The mean age of the patients at the time of revision was 64 years (41-77 years). All of the revised femoral com-ponents were cemented stems,with first-generation cement technique in 18 hips and second-generation ce-ment technique in 2 hips. The indications for hip arthroplasty included osteonecrosis of the femoral head in 14 hips and femoral neck fracture in 6 hips. The interval from primary hip arthroplasty to revision surgery ranged from 5 to 17 years, with an average of 11.5 years. There were 4 re-revisions in this group. Based on Paprosky classification for bone deficiency, 3 hips were of type I, 6 of type II and 11 of type IIIA. The com-ponents implanted included AML (DePuy) in 5 cases , Solution (DePuy)in 7, full-coated (Zimmer)in 6 and Perfecta Extend Stems (Wright Med) in 2. The postoperative stability was evaluated according to the Engh criteria. The patients were followed for an average of 40 months (18-60). Results At the latest fol-low-up, the mean Harris score was improved from 40 to 85 points postoperatively. The bony ingrowths were found in 17 hips and the fibrosis stability in 3 on postoperative radiographic evaluation. There were no re-revisions in this group. The bone remodeling was observed in all osteolytic zones. Conclusion In the pres-ence of bone loss in the proximal metaphyseal region of the femur, the extensive porous-coated femoral com-ponents may provide a bypass for the deficient proximal bone. It may further obtain initial optimizing pros-thesis-bone fitting and an axial anti-rotational stability in the relatively normal diaphyseal region of the fe-mur to allow the reliable biological fixation with bony ingrowths.

Objectives To analyze the clinical features, diagnosis and treatment of Lemierre syndrome. Methods The clinical data of one case of Lemierre syndrome were retrospectively analyzed. The relevant literatures were reviewed. Results The primary infection of the patient was oral infection, and jugular vein thrombosis and metastatic lung abscess were followed. The blood culture showed that Staphylococcus aureus was positive. Lemierre syndrome was diagnosed. After anticoagulation and anti-infection treatment, the symptoms were improved. Conclusion Lemierre syndrome should be considered in present of jugular vein thrombosis and pulmonary abscess caused by infection.

Objective To investigate the protective effects of antioxidant taurine plus metoprolol on the blood pressure(BP)and blood vessel function of elderly spontaneously hypertensive rats(SHR).Methods SHRs were divided into three groups (6 rats,each):metoprolol group (100 mg · kg-1 · d-1,intragastric administration);taurine group (200 mg · kg-1 · d-1,intraperitoneal injection);taurine plus metoprolol group(metoprolol 100 mg· kg-1 · d-1,intragastric administration ± taurine 200 mg· kg-1 · d-1,intraperitoneal injection).The control group[6 Wistar-Kyoto(WKY) rats]was treated with the same volume of sterile normal saline on the same schedule in intragastric administration and intraperitoneal injection.Blood pressure variability(BPV),diurnal variation of BP,the level of glutathion peroxidase (GSH-Px),malonaldehyde (MDA) and the aorta GSTM1 enzyme expression were evaluated before and 14 days after treatment.Results The serum GSH-Px activities were higher in metoprolol group[(2 759.8 ± 117.6) kU/L],taurine group [(2 848.0 ± 280.2) kU/L] and taurine plus metoprolol group[(3 052.8±283.7)kU/L]than in control group[(2 368.0± 60.4) kU/L] (all P＜0.05).Fourteen days after treatment,MDA level was significantly lower in taurine group[(9.5±0.7)ng/L,P＜0.01]than in control group[(13.7±1.5)ng/L].However,there was no statistical difference in MDA level between metoprolol group/taurine plus metoprolol group and control group.Forty weeks after treatment with taurine,GSTM1 protein expression was increased,but it had no statistical difference.Conclusions The combined antioxidant taurine and metoprolol can effectively decrease BPV of elderly SHRs,in which the antioxidant effect might be associated with elevated GSTM1 protein expression.

Osteoarthritis (OA) is the main reason of joint pain and dysfunction in the elderly in China, and its incidence is increasing year by year. In addition to the joint peripheral osteophyte formation and degeneration of articular cartilage, in?flammation, as one of the dominant pathological changes in OA, is causing more and more attention. Pro-inflammatory cyto?kines (PIC) are important mediators of inflammation. The increased level of PIC in OA can lead to systemic and local inflam?mation, results in further destruction of many kinds of tissues in joint (such as cartilage), and accelerates the development of OA. Besides, the severity of inflammation is closely related to the clinical symptoms of OA. Therefore, it is important to un?derstand the role of PIC in the pathogenesis of OA. From the perspective of the relationship between pro-inflammatory fac?tors and OA and the molecular mechanism, this article reviews the research progress in this field, which provides new con?cepts for diagnose and treatment of OA.

Objective To explore the risk factors in the prognosis of patients with severe multiple trauma related factors.Methods Ninety-three patients with severe multiple trauma(ISS score≥16 points) were selected as our subjects,who all hospitalized in the second hospital affiliated to Dalian medical University.Among of which,38 cases' ISS score was 16-25,and 55 cases' ISS score was higher and equal to 25.Clinical data and general information were recorded.ISS score,APACHE Ⅱ score and 6 h lactate clearance rate score were measured.Results Twenty-seven dead among these 93 cases and the mortality was 29.03％.There were significant differences in terms of ISS score,APACHE Ⅱ score,lactate level when entering ICU,6 h lactate level and 6 h lactate clearance rate between death patients (27 cases) and survival patients (66 cases) (t =9.846,9.812,7.112,7.012,9.831 ; P ＜ 0.001).In multiple organ dysfunction syndrome (MODS) patients,the mortality of ISS score:16-25 group was different from that of ISS score≥25 (15.78％ (6/38) vs.35.18％ (21/93),x2 =21.52,P ＜0.001).Among the 93 cases of severe multiple trauma,35 cases with MODS(37.6％ (35/93)),and 20 cases of which were dead(57.1％ (20/35)).There was statistic difference between MODS group(35 cases) and non-MODS(58 cases) in term of mortality(37.6％ (35/93) vs.12.1％ (7/58) ;x2 =21.52,P ＜ 0.001).Multivariate logistic regression analysis showed that the ISS score,APACHE Ⅱ score,6 h lactate clearance rate and MODS were independently prognostic correlation factors (P ＜ 0.05).Operating characteristic curve (ROC) showed that AUC of ISS score was 0.735 (95 ％ CI 0.629-0.842),of APACHE Ⅱ score was 0.888 (95％ CI 0.821 =0.956),of 6 h lactate clearance rate score was 0.951 (95％ CI 0.906 -0.997).Conclusion The factors of ISS score,APPCHE Ⅱ assessment,6 h lactate clearance rate,the occurrence of MODS are independent prognostic factors.

Objective To investigate the expression of human papillomavirus (HPV) L1 protein in lesional tissue of condyloma acuminatum and its clinical significance.Methods Forty-three patients with condyloma acuminatum were included in this study,and received CO2 laser therapy.Tissue samples were resected from the lesions of these patients at their first visit before treatment.Immunohistochemistry was used to determine the expression of HPV L1 protein in these samples.Follow up was carried out once every 2 weeks for 3 months to assess the recurrence rate and frequency in these patients after treatment.Results HPV L1 protein was detected in 83.72％ (36/43) of these tissue samples.The expression rate of HPV L1 protein decreased sequentially from patients infected with HPV 6/11,patients with both HPV 6/11 and 16/18,to those with HPV16/18 (x2 =17.90,P ＜ 0.01).During the 12 weeks of follow up,the recurrence rate was 69.77％ (30/43) with the average number of recurrence of 2.16.There was a sequential reduction in the recurrence rate and number from patients with strong expression of HPV L1 protein,to those with moderate expression,slight expression and negative expression (x2 =8.02,46.92,P ＜ 0.05 and 0.01,respectively).The expression intensity of HPV L1 protein was negatively correlated with the recurrence rate and frequency (rs =-0.429,-0.696,respectively,both P ＜ 0.01).Conclusion HPV L1 protein may serve as a helpful molecular biomarker for the prediction of prognosis and recurrence of condyloma acuminatum.
