OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

Objective To evaluate the influence of C-reactive protein (CRP),insulin resistance (IR) and epicardial fat volume (EFV) on the extent of coronary atherosclerosis in patients with different body mass index(BMl).Methods One hundred and three patients with coronary artery disease were involved in current study who underwent 64-slice dual source CT and percutaneous coronary angiography.Measurements of height,weight,waist circumference (WC) were recorded,and BMI was calculated.All patients were divided into obesity group (n =45) and non-obesity group (n =58) based on BMI.EFV were calculated through 64-slice dual source CT.Blood samples were collected for biochemical examination.Gensini score were adopted to quantify the severity of coronary artery stenosis.The relationship between Gensini score and EFV,CRP and homeostasis model assessment-insulin resistance(HOMA-IR) index were statistical analyzed by SPSS16.0 software.Results The level of CRP,WC,EFV and BMI in obesity group were (11.0 ± 5.8) mg/L,(96.1 ± 7.0) cm,(122.7 ± 43.3) cm3,(27.9 ± 2.9) kg/m2 respectively,significantly higher than those in non-obesity group ((6.5 ± 3.4) mg/L,(86.4 ± 7.6) cm,(92.9 ± 39.5) cm3,(22.4 ± 1.9) kg/m2) and the differences were significant (t =2.24,6.74,3.64,11.74,and P ＜ 0.05).CRP were positively correlated with EFV (r =0.404,0.364,P ＜0.05) in both obesity and non-obesity group,While HOMA-IR were only associated with BMI in obese group(r =0.322,P ＜0.05).Gensini score in non-obesity groups were positively related with EFV and CRP (r =0.358,0.315,P ＜ 0.05),while in obesity groups were positively related with EFV,CRP and HOMA-IR(r =0.348,0.297,0.384; P ＜ 0.05).The associations between Gensini score and CRP were not significant in obesity group after adjusting BMI and WC.Multiple linear regression analysis showed that EFV and diabetes mellitus were independent risk factors of patient Gensini score.Conclusion Coronary atherosclerosis is positively related with EFV and CRP in all patients.While,coronary atherosclerosis is influenced by BMI,WC and HOMA-IR in obese group.EFV is an independent risk factor of coronary atherosclerosis.

Objective Epicardial fat volume ( EFV) was a risk factor for coronary heart disease ( CHD) , but there is little research regarding the relationship of EFV with insulin resistance ( IR) and CHD in patients with metabolic syndrome ( MS) .The aim of the article was to explore the effect of EFV in patients with MS on CHD and IR . Methods Patients with MS treated by percutane-ous coronary angiography ( CAG) in our hospital from February 2013 to August 2013 were recruited in this study .The data of height , weight, waist circumference(WC) and hip circumference(HP) were recorded.EFV were measured by MSCT.Fasting blood samples were collected for blood biochemical test . Results EFV in patients with MS was in positive relation with IR index (IRI)(r=0.335, P<0.001) and CHD (r=0.321, P<0.05), and the correlation still remained when the influences of WC and body mass index (BMI) were excluded.Logistic regression analysis showed that EFV was an independent risk factor for CHD (P<0.05), while linear regression analysis indicated EFV , BMI and LDL-C were the risk factors for IRI .ROC curves analysis proved EFV and BMI had diag-nosis value for IRI, and the areas under curve of EFV were 0.755 and 0.679 (P<0.05) respectively. Conclusion EFV is an in-dependent risk factor for CHD and IRI in patients with MS , and EFV has an advantage over BMI in the diagnosis value of IRI .

Objective To investigate the therapeutic effect and adverse effects of the teniposide-based regimen in patients with primary central nervous system lymphoma (PCNSL). Methods Between March 2011 and July 2013, 16 patients with PCNSL were diagnosed and treated. The clinical characteristics, diagnosis,therapy, results and adverse effects were analyzed. Results Totally 16 patients were enrolled and diagnosed as primary central nervous system diffuse large B-cell lymphoma. All patients received teniposide-based regimen chemotherapy and 9 patients received teniposide plus rituximab. The overall response rate was 87.5 % (14/16), including 10 cases of CR and 4 cases of PR. With a median follow-up of 13.5 months, the progression-free survival (PFS) and overall survival (OS) rates of 2 years were 29.9 % and 66.7 %, respectively. The mainly hematological adverse events were neutropenia, including grade 3 in 4 cases (25 %) and grade 4 just in one case. There was one case of treatment related death. Conclusions The response rate of teniposide-based regimen for PCNSL is promising. The 2 year PFS and OS rates are even higher than results of traditional high-dose methotrexate regimen. The teniposide-based regimen is well tolerated, and the adverse events are acceptable.

OBJECTIVE To investigate the protective effect of Sika deer velvet antler protein (SVPr) against renal toxicity in mice and its mechanism.METHODS Forty ICR mice were randomly divided into 5 groups:normal control group (ig distilled water),model group (ig distilled water for 7 d,on the 7th day,ip cisplatin 25 mg·kg-1 to establish the model,afterwards ig distilled water for 3 d) and SVPr 5,10 and 20 mg· kg-1 groups (ig SVPr for 7 d,cisplatin 25 mg· kg-1 was provided 2 h after the last administration,then ig SVPr for 3 d).Testing kits were adopted for the measurement of renal indexes in mice,such as blood urea nitrogen (BUN) and serum creatinine (SCr);oxidative stress indictors of super oxide dismutase (SOD),catalase (CAT),glutathione (GSH) and malondialdehyde (MDA);inflammation indictor levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6).Caspase 3,Bax and Bcl-2 were detected via Western blotting,and renal pathological changes were observed by HE staining.RESULTS SVPr (5,10 and 20 mg·kg-1) significantly reduced the levels of SCr,BUN,MDA,TNF-α and IL-6,and the expressions of caspase 3 and Bax (P＜0.05),but increased the activities of SOD,CAT and GSH,and the expression of Bcl-2 (P＜0.05).The renal pathological changes were improved.CONCLUSION SVPr can reduce renal toxicity induced by cisplatin in mice,and the mechanism is probably related to inhibiting oxidative stress or inflammatory reaction and improving cell apoptosis.

Objective To analyze the clinical characteristics , diagnosis, therapy and prognosis of new diagnosed pri-mary gastric diffuse large B cell lymphoma ( PGDLBCL) and to discuss the efficacy of rituximab .Methods Between Jan 2005 and May 2012 , twenty-six new-diagnosed PGDLBCL patients were reviewed retrospectively .The clinical characteris-tics, diagnosis, therapy, results and prognostic factors were analyzed .Results There were 14 males and 12 females.Their age ranged from 25 to 82 (median, 50.1) years old.The most common symptom was stomachache .Treatment strategies were chemotherapy alone ( n=9) [ scheduled as cyclophosphamide , doxorubicin , vincristine and prednisone ( CHOP) and CHOP-like] and chemotherapy combined with rituximab (n=17), followed by radiotherapy of the stomach with or without regional nodes .All clinical and pathological features were similar between the two groups .The median follow-up time was 40 months.The overall response rate was 100%(9/9)in CHOP group, including 55.56%(5/9) CR, and 93.75%(15/16) in RCHOP group including 50%(8/16) CR (P>0.05).The total PFS and OS of 5 years were 60.3%and 74.4%respectively.The PFS in CHOP group and RCHOP group was 66.7% and 58.9%, respectively,and the OS was 66.7%and 84.6%, respectively.Although the OS of RCHOP group was much better than that of CHOP group , there was no sta-tistically significant difference.Univariate analysis showed that IPI (P<0.05) and Lugano staging (P<0.05) were inde-pendent factors of survival in patients with PGDLBCL .Conclusion Chemotherapy could be the first-line therapy of PGDL-BCL.The overall survival rate might be increased by adding rituximab to chemotherapy .The Lugano stage and IPI are im-portant prognostic factors .
