OBJECTIVETo compare the early clinical outcomes of primary total knee arthroplasty in the valgus knee between mobile-bearing prosthesis and fixed-bearing prosthesis.

METHODSFrom January 2011 to December 2013, 17 patients (23 knees) treated by the same surgeon were selected for a retrospective study in the First Hospital of Jilin University, including 2 males and 15 females with a mean age of 61.5 years old (48 to 75 years). The pre-operative diagnosis included osteoarthritis (14 patients, 19 knees) and rheumatoid arthritis (3 patients, 4 knees). The patients with valgus deformity were divided into group A and group B. The patients in group A were treated with the fixed-bearing prosthesis (9 patients, 12 knees), and the patients in group B were treated with the mobile-bearing prosthesis (8 patients, 11 knees). The Knee Society Score (KSS), Hosptial for Special Surgery (HSS), Western Ontario MacMaster (WOMAC), the range of motion (ROM) and femorotibial angle were collected at pre-operation and post-operation follow-up for statistical analysis.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 36 months (mean 25 months). The valgus deformity was corrected in all patients, and there were significant differences for all patients between pre-operation and post-operation at the latest follow-up with regard to the KSS knee score, function score, HSS score, WOMAC score, ROM and femorotibial angle (P<0.01). There were no significant differences in KSS knee score, function score, HSS score, WOMAC score, improvement in ROM and femorotibial angle between two groups at the latest follow-up. However there were significant differences in ROM (P<0.05) between fixed-bearing group (101.8±8.8)° and mobile-bearing group (108.4±7.2)° at the latest follow-up. No case with spin-out of mobile bearing was observed. There were no complications in any patient, such as infection, common peroneal nerve injury, dislocation and instability. The X-ary imaging showed no osteolysis or implant loosening.

CONCLUSIONThe early clinical outcomes of primary total knee arthroplasty by using mobile-bearing prosthesis and fixed-bearing prosthesis are satisfactory for the treatment of the valgus knee, and the short term clinical outcomes of mobile-bearing TKA and fixed-bearing TKA are similar.

Objective To observe the efficacy and adverse reaction of ozone therapy combined with gemcitabine and cisplatin (GP) regimen in patients with advanced non-small cell lung cancer.Methods Fifty-five patients with advanced non-small cell lung cancer were enrolled and allocated to treatment group (28 cases) and control group (27 cases).The patients in treatment group received ozone therapy combined with GP regimen,and the patients in control group received GP regimen only.The efficacy,quality of life,adverse reaction and cellular immune function after treatment was compared between two groups.Results There was no significant difference in the efficacy between two groups (P ＞ 0.05).The quality of life after treatment in treatment group was better than that in control group (P ＜ 0.05).The liver function damage in treatment group was lower than that in control group (P ＜ 0.05).The cellular immune function in treatment group was stronger than that in control group (P ＜ 0.05).Conclusion Ozone therapy combined with GP regimen can effectively alleviate adverse induced by GP regimen chemotherapy and significantly improve the quality of life in patients with advanced non-small cell lung cancer.

Objective To assess the causes of sildenafil failure and the feasibility of successfully rechallenging non-responding patients. Methods A total of 126 consecutive erectile dysfunction (ED) patients from Jan 2009 to Dec 2009 who claimed poor response to sildenafil (sildenafil 100 mg on demand, at lease 4 epiodes) were enrolled into the study. All patients received sexual reeducation and were treated with sildenafil, taken on a daily dose of 50 mg for 4 weeks. The International Index of Erectile Function-5 (IIEF-5), Rigiscan, serum testosterone or penile Doppler were used to evaluate ED and the cause of on-demand sildenafil failure. End point efficacy of rechallenging was evaluated using the IIEF-5 and the sexual encounter profile (SEP) 'Were you able to insert your penis into your partner's vagina?' and 'Did your erection last long enough to achieve successful intercourse?'. Results The recruited patients comprised of 41 cases with psychological ED, 39 cases with hypogonadism ED, 28 cases with diabetes mellitus ED and 18 cases with vascular ED. Compared with pretreatment and on-demand sildenafil baseline, daily administration of sildenafil significantly enhanced all efficacy outcome variables. The IIEF-5 was significantly improved after daily sildenafil (12.3 ± 2.9 vs18. 8±4.4, P＜0.01), 78 patients responded to daily sildenafil. The overall salvage rate was 61.9%(78/126). Conclusions Sexual reeducation and daily administration of sildenafil may be able to salvage many patients with ED who were sildenafil non-responders.

Objective To estabalish a new conception, Erectile Dysfunction-no sexual life (ED-NS), so as create an evaluating questionnaire, Self-estimation Index of erectile function-No sexual life (SIEF-NS) so as to investigate its clinical reliability. Methods The conception of ED-NS was identified and the SIEF-NS questionnaire was established. Patients who complained of ED-NS and normal controls were enrolled into the research and assessed the erectile function was assessed with SIEF-NS.The SIEF-NS includes 12 questions, such as sexual libido, general erectile function, nocturnal penile erection, erectile function during foreplay, erectile function during audio-video sexual stimulation,confidence, depression, etc and each question has 5 point scales. Results Sixty-one ED-NS patients and 57 controls were enrolled into the study and assessed erectile function with SIEF-NS. The mean score of each question and integral score of SIEF-NS in ED-NS patients were significantly different from normal controls (P＜0. 05). When the integral score was 35 points according to the ROC curve of integral score, the sensitivity of SIEF-NS was 88.5% and specificity was 96. 5%. Conclusions ED-NS is a new conception to define patients who have erectile dysfunction without sexual life. SIEFNS is suggested to be a useful method for the evaluation of ED-NS patients.

Objective To evaluate the relationship between the amount of grafted cells and the incidence of acute graft versus host disease (aGVHD) after haploid hematopoietic stem cell transplantation (haplo-HSCT). Methods Data of 68 patients who underwent haplo-HSCT from Jan 2009 to Dec 2013 were analyzed retrospectively. Influences of different factors on the incidence of Ⅲ-Ⅳ degree of aGVHD after HSCT were evaluated. Results 68 patients including 42 males and 26 females were 5/10-9/10 HLA match with 19 father donors, 24 mother donors, 16 sibling donors and 9 children donors. 51 patients not suffered Ⅲ-Ⅳdegree of aGVHD included 32 males and 19 females with the mean age of 20 years old (5-55 years old). 17 patients sufferedⅢ-Ⅳdegree of aGVHD including 10 males and 7 females with the mean age of 23 years old (5-54 years old). There were no significant differences in the amount of the grafted mononuclear cells (MNC) and CD34+cells, and the white blood cell counts (WBC) and platelet count (Plt) recovered time between two groups (P>0.05). However, MNC number was related to CD34+cell number (P<0.05) and WBC recover time (P<0.05), and the CD34+cells number was related to WBC and Plt recover time (P< 0.05). Conclusion The incidence of Ⅲ-Ⅳ degree of aGVHD is unrelated to the amount of grafted MNC, and CD34+cells.

ObjectiveTo assess the cause of tadalafil failure and the feasibility of successfully rechallenging nonresponding patients.Methods A total of 80 consecutive erectile dysfunction ( ED ) patients who claimed poor response to tadalafil were enrolled into the study.A self-administered tadalafil-use questionnaire composed of eight questions was applied to assess how they had used tadalafil.Subjects were given thorough instruction based on individual answers and four doses of tadalafil 20mg.After a 2-week follow-up,end point efficacy of rechallenge was evaluated using the sexual encounter profile (SEP),which was recommended by international advisory panel in 2004.ResultsA total of 45 subjects had one or more areas of major suboptimal use of tadalafil:21.2％ did not know that sexual stimulation was necessary for tadalafil to work,87.5％ attempted to use tadalafil less than four times,57.5％ took a maximal dose less than 20 mg,and 84％ felt nervous or anxious.Of the 65 patients undergoing tadalafil rechallenge,30 patients answered “yes” to SEP2 and SEP3.The response rate to rechallenge was 46.2％ ( 30/65 ).ConclusionsInappropriate use of tadalafil was major cause of tadalafil non-pesponse.The efficacy of tadalafil could be improved to a better extent by education of patients.

Objective To investigate whether the gene polymorphisms of cytochrome P450(CYP) 2E1 are associated with the risk of anti-tuberculosis drug induced hepatotoxity (ADIH).Methods In this case control study, 339 patients who matched the diagnosis criteria of tuberculosis were included. The gcneral healthy status and liver biochemical parameters were checked in all these patients. Polymerase chain reaction-restriction fragment length polymorphism (PCR RFLP) technique was used to determine CYP 2Et polymorphisms. The statistic analysis were performed by using both univariate and multivariate Logistic regression analysis. Results The allele frequencies of CYP 2E1 7632T/A, 1019C/T and 1259G/C in 103 tuberculosis patients of ADIH group were 17.5%, 26.2%and 27.2 % respectively, while those in 236 tuberculosis patients of control group were 29.7 % ,39.4 %and 40.7%, respectively (x2 =5.539, P＜0.05; x2 =5.458, P＜0.05; x2 =5.628, P＜0.05). The results of univariate analysis demonstrated that the risk of concurrent ADIH was significantly higher in patients with wild genotypes of CYP 2E1-7632T/A, CYP 2E1-1259G/C, CYP 2E1-1019C/T than in patients with other genotypes. After adjusted for sex, occupation and alcohol consumption status, the results of multivariate Logistic regression analysis also showed that wild genotypes of CYP 2E1-7632T/A, CYP 2El-1259G/C, CYP 2E1-1019C/T were significantly associated with higher risk of ADIH. The results of interaction analysis indicated that the wild genotypes of CYP 2E1-7632T/A and CYP 2E1-1259G/C or CYP 2E1-1019C/T had synergetic effects on the development of ADIH.Conclusions The risk of concurrent ADIH is significantly higher in patients with wild genotypes of CYP 2E1-7632T/A, CYP 2E1-1259G/C, CYP 2E1-1019C/T compared to patients with othergenotypes. Wild genotypes of CYP 2E1-7632T/A and CYP 2E1-1259G/C or CYP 2El-1019C/T have synergetic effects on the development of ADIH.

Objective To improve the diagnosis efficiency of patients with angioimmunoblastic T-cell lymphoma (AILT)by analyzing the clinical characteristics and curative effect of AILT. Methods Retrospective studies were used on clinicopathological features,immunophenotypes,treatment and survival of 20 angioimmunoblastic T-cell lymphoma patients,who were collected between January 2005 and January 2010 of Beijing Military General Hospital. Results In the 20 patients receiving chemotherapy,the median age was 55.9 years old.All of the 20 had lymph nodes and 11 of whom were accompanied with B group of symptoms,which were confirmed by lymph node biopsy and T cell antigen CD3, CD45Ro positive expression in all the patients. ALL of the patients received the CHOP regimen and combining with other treatment such as DICE,ESHAP, Hyper-CVAD or autologous hematopoietic stem cell transplantation. A follow-up by 5 to 69 months showed that median survival was 20.2 (5-69) months and 1,2,and 3-year disease free survival (DFS) were 67 ％,33 ％,and 11％ respectively.8 patients of the group (40 ％) with a sustained remission (CCS) respectively survived 63,47,27,24,24,12,5,1 months so far.Conclusion Most patients were older with many complications during chemotherapy, which resulted in easy relapse, and even the symptoms were alleviated at the early stage of the chemotherapy. IPI prognostic index is more important with long-term survival in AITL.Therefore further studies are required to improve the outcome.

Objective To assess the causes of erectile dysfunction (ED) after spinal or pelvic injuries.Methods From 2005 to 2009,a total of 67 patients who complained of ED after pelvic fracture or spinal injures were evaluated with the average patient age of 32 yrs (18 to 64) and average injury period of 38 mon (3 -144).Of the 67 patients,56 had pelvic fractures (84％) and 11 patients had spinal injures ( 16％ ).All patients reported normal erectile function before the injuries.All patients answered IIEF-5 and underwent nocturnal penile tumescence (NPT) tests (Rigiscan assessment system,continuing three nights).If resuls of the test were abnormal,color penile duplex ultrasound ( CDU ) with intracavernous injection were performed.Normal nocturnal erectile function was defined as at least three tumescence periods lasting more the 10 minutes with rigidity at the penile tip of at least 70％.Patients with abnormal nocturnal erectile function were diagnosed with organic ED.Patients who achieved a fully erect penis after intracavernous injection,and who had a peak systolic velocity ( PSV ) of less than 25 em/s on CDU were diagnosed with arterial ED.Patients with a PSV of more than 25 cm/s and an end diastolic velocity (EDV) of more than 5 cm/s on CDU indicated venous leakage.Patients with organic ED who had normal vascular function on duplex ultrasound were diagnosed with neurogenic ED.Results All patients reported IIEF-5 less than 8,NPT tests showed that all patients had organic ED.Of the patients with pelvic fracture,neurogenic ED,arterial ED and venous leakage was diagnosed in 24 patients (43％),22 patients (39％) and 10 patients (18％),respectively.However,the patients with spinal injuries were all diagnosed with neurogenic ED.Conclusions Pelvic fracture and spinal injury can cause organic ED.Vascular ED is common in pelvic fracture,however,neurogenic ED was the most common type of ED in spinal injury.
