Background and purpose:Solitary plasmacytoma of bone(SBP) is a rare disease,reports releveant to this disease are rarely seen. The purpose of this study was to investigate the relation between the clinical features and the prognosis of solitary plasmacytoma of bone. Methods:We reviewed the data of 12 patients diagnosed with solitary plasmacytoma of bone from 1998 to 2007 in Peking University third hospital,the clinical features,treatment and prognosis of the patients were analyzed retrospectively. Results:The age ranged from 37-71 years(mean 49.6 years) ,the male/female ratio was 3 to 1. Immunophenotype analysis showed that 11(91.6%) cases were positive for CD79a,10(83.3%) positive forVS38C,and all negative for CD20. With 12 to 87 months follow-up(average 40?22 months) ,three cases(33%) developed to multiple myeloma,two of them died from infection,the median survival time was 73 months,the 3 year and 5 year survival rate were 90 percent and 75 percent respectively. Conclusion:Middle and old male are more likely to develop SP. The prognosis is good,but some of them can progress to multiple myeloma.

OBJECTIVETo observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs.
METHODSOne hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation.
RESULTSThe incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05).
CONCLUSIONThe general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

Objective To study the frequency of diffuse large B-cell lymphoma (DLBCL) with multi-genetic alteration, and its correlation with c-myc, bcl-2 and bcl-6 protein expression. Methods 50 cases diagnosed with DLBCL from January 2012 to December 2016 were collected. The expression of c-myc, bcl-2 and bcl-6 was analyzed by immunohistochemistry. Interphase fluorescence in situ hybridization (I-FISH) analysis was performed to identify the genetic alteration of c-myc, bcl-2 and bcl-6. Results In all cases, there were 27 males and 23 females with a median age of 50 years (range: 3-85 years). 23 (46.00 %) cases were defined as primary nodal DLBCL and 27 (54.00 %) cases were primary extra-nodal DLBCL, with gastrointestinal tract (48.15 %, 13/27) being the most common site of involvement. c-myc protein expression was detected in 94.00 % (47/50) cases, in which 82.00 % (41/47) cases exhibited high levels of c-myc expression with positive nuclear staining observed in over 40.00 % of tumor cells. The positive rate of bcl-2 protein was 84.00 % (42/50), 76 % (38/50) cases presented with high-level bcl-2 expression. Concurrent high expression of c-myc and bcl-2 were presented in 18 cases (36.00%). FISH analysis demonstrated c-myc gene rearrangement in 7 cases (14.00 %) and amplification in 2 cases (4.00 %). bcl-2 gene rearrangement was detected in 6 cases (12.00 %) and 4 cases (8.00 %) exhibited gene amplification. bcl-6 gene rearrangement was identified in 8 cases (16.00%), amplification in 3 cases (6.00%), and 1 case concomitantly harbored the rearrangement and amplification of bcl-6. Multi-genetic alterations were defined in 4 cases with 3 cases fulfilling the criteria for double-hit lymphoma (DHL) and 1 case for triple-hit lymphoma (THL). For the cases with concomitant high-level expression of c-myc and bcl-2 proteins, 3 cases (16.67 %) was detected with multi-genetic alterations, including 2 cases for DHL and 1 case for THL. Conclusions The proportion of DLBCL with multi-genetic alterations is 8.00 % in this study. The genetic alterations are not consistently correlated with the protein expression. The molecular genetic testing is reliable for the identification of DHL.

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 efficacy of microvasoepididymostomy for the treatment of obstructive azoospermia. Methods Ninety-eight patients were confirmed as obstructive azoospermia by infertility investigations.The mean (range) age was 31 (20-43) years.The mean duration of obstruetion was 4 years.All patients were seen by the surgeon for a complete history and physical examination.Semen analyses proved azoopermia,serum levels of sexual hormone were normal and testicular function for production of sperms were normal certified by biopsy.All patients with suspected epididymal or vasal obstruction were offered scrotal exploration.The decision for microvasoepididymostomy was made during surgery,based on the pateney of the vas towards the abdomen documented by saline and sperm fragments containing in the epididymal fluid on intraoperative light-microscopic examination.Microvasoepididymostomy was performed in 58 patients documented epididymal obstruction The initial semen analysis was then done after usually 3 months postoperatively.Patency was arbitrarily defined as>10 000 sperm/mL in ejaculate in at least one semen analysis after surgery.Postoperative patency rate and postoperative impregnation rate were followed. Results Fifty patients were followed up for 3-29 months,8 cases lost.Sperm was found by semen analysis in 36 patients.Sperm density was 4×104-2×108 sperms/ml and motility was 2%-70%.Semen analysis reveals azoospermia in 6 patients and the patients were counseled to undergo further testing to determine the ultimate outcome of the procedure.Natural conception occurred in 14 patients followed for more than 12 months.The overall pateney rate was 72%(36/50).Among patients with a follow-up of>6 months,the natural paternity rate was 28%(14/50).The median time to achieve a natural pregnancy was 6.6 (4.0-10.0)months. Conclusion A more favourable patency can be achieved using microsurgical intussusception vasoepididymostomy and a part of patients with obstructive azoospermia can be cured by this means.
