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.

Objective To assess the effect and feasibility of group reminiscence therapy on depression in the elderly.Methods We searched the Cochrane Central Register of Controlled Trials (-2013),Medline (1982-2013),Embase (1974 2013),AMED (-2013),CINAHL(-2013),CMB (1994-2013),VIP,CNKI and Wanfang to collect the randomized controlled trials (RCTs) in which the group reminiscence therapy was used to treat depression in elderly patients.The studies were selected according to the inclusion and exclusion criteria by two reviewers,and the quality of included studies was evaluated according to Cochrane Handbook and performed meta analyses by using the Cochrane Collaboration's RevMan 5.2 software.Results A total of 10 RCTs involving 944 patients were included.The results of meta-analysis showed that as compared with conventional treatment,group reminiscence therapy on the basis of conventional treatment was more effective in decreasing depression score [MD=-4.86,95 ％ C I(-5.10,-4.65)].Compared with psychological counseling,group reminiscence therapy had more effect on decreasing depression score [MD=-9.34,95％ CI (-10.77,-7.91)].There was no significant difference in the dropout rate between group reminiscence therapy and other control treatments [RR=1.22,95％ CI (0.79-1.88)].The descriptive analysis showed that group reminiscence therapy was effective in alleviating the symptoms of depression.Conclusions Group reminiscence therapy can improve the symptoms of depression in elderly patients and conforms to the principle of economic benefit.However,the results should be interpreted with caution because of the low quality of the included studies.

Objective To explore the pharmacodynamic action of the extract from raw materials of Rhizoma Anemarrhenae and Cortex Phellode ndri, a classic herb pair in traditional Chinese medicine, on mice with diabetic peripheral neuropathy(DNP). Methods The mice were administrated with intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) and fed with high-fat diet to establish the DNP mouse model. One hundred and sixty male C57BL/6j mice were divided into normal group, model group, metfomin group(130 mg/kg), Xuezhikang group(200 mg/kg), high- and low-dose Rhizoma Anemarrhenae extract group(360, 90 mg/kg) , high-and low-dose Cortex Phellodendri extract group(135, 45 mg/kg), 20 mice in each group. The medication lasted for 24 weeks. On medication week 8, 16 and 24, the plasma levels of glucose (GLU), total cholesterol (TC), triglyceride(TG), low density lipoprotein-cholesterol(LDL-C) and insulin(INS) were determined respectively. On medication week 10, oral glucose tolerance test(OGTT)was carried out. On medication week 24, the plasma nuclear factor kappa B(NF-κB) activity and the plasma levels of transforming growth factor-beta 1(TGF-β1), superoxide dismutase(SOD) and reduced glutathione(GSH) were detected. Results Five weeks after injection of STZ, the body mass of the model group was firstly increased and then decreased, and FBG was increased(P<0.05 compared with the normal group). Compared with the normal group, FBG, TC, TG, LDL-C and INS levels were increased(P<0.01 or P<0.001), plasma NF-κB activity, TGF-β1 and SOD levels were enhanced, and GSH level was decreased in the model group, the difference being statistically significant (P<0.01 or P<0.001). Contrasted with the model group, FBG, TC, TG, LDL-C and INS levels in high-and low-dose Rhizoma Anemarrhenae extract group and in high-and low-dose Cortex Phellodendri extract group were decreased to various degrees. After continuous medication, plasma NF-κB activity and TGF-β1 and SOD levels in high-dose Rhizoma Anemarrhenae extract group and in high-dose Cortex Phellodendri extract group were reduced(P<0.05 or P<0.001), and plasma GSH level was increased(P<0.01). Conclusion Extract from raw materials of Rhizoma Anemarrhenae and Cortex Phellodendri has obvious hypoglycemic effect and protective effect on experimental mice with DPN.

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.

OBJECTIVETo explore the effect of acupuncture-anesthetic composite anesthesia (AACA) on the incidence of postoperative cognitive dysfunction (POCD) and changes of TNF-alpha, IL-1beta, and IL-6 in elderly patients.

METHODSTotally 83 patients undergoing surgical resection of gastrointestinal tumor were randomly assigned to the simple anesthesia group (A group, 41 cases) and the AACA group (B group, 42 cases). Patients in Group A received endotracheal general anesthesia. Those in Group B were induced by acupuncture anesthesia for 30 min by needling at Baihui (DU20), Neiguan (PC6), Zusanli (ST36). The electro-acupuncture (EA) apparatus was connected after arrival of qi, with the wave pattern of density 2/100 Hz. The stimulus intensity was set by patients' tolerance, with the peak current of 5 mA. Then the endotracheal general anesthesia was performed and the EA lasted till the end of the surgery. The cognitive function of all patients was assessed before operation and at day 3 after operation using mini-mental state examination (MMSE). POCD was confirmed if with one or more decreased stand- ard. The peripheral venous blood was collected before anesthesia induction (TO), immediately at the end of surgery (T1), 24 h after operation (T2), and 48 h after operation (T3), and serum concentrations of IL-1beta, IL-6, and TNF-alpha were correspondingly measured using ELISA.

RESULTSThe postoperative anesthesia awakening time was shorter in Group B than in Group A [(20.37 +/- 6.09) min vs (29.24 +/- 7.48) min, P < 0.05]. The remifentanil dose used during the operation was less in Group B than in Group A (P < 0.05). The incidence of POCD at day 3 was lower in Group B than in Group A [10/41 (23.8%) vs 15/42 (36.5%), P < 0.05]. The concentrations of IL-1beta, IL-6, and TNF-alpha at T1-T3 were higher than those at TO in the two groups (P < 0.05). The increment of TNF-alpha and IL-1beta was less in Group B than in Group A (P < 0.05). CONCLUSION AACA could reduce the incidence of POCD and inhibit postoperative release of TNF-alpha, IL-1beta, and IL-6 in elderly patients undergoing colorectal cancer resection.

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.

Objective To compare the circumferential approach and suprapubic approach for correcting the concealed penis. Methods Thirty-four patients received circumferential approach (group A,18 cases)or suprapubic approach(group B,15 cases)randomly for the concealed penis.The length of penis without erection before and after surgery treatment,patients'satisfaction and surgical complications were evaluated.All the patients were followed at least 6 months after operation.Results The penile length before and after surgery in group A were(1.78±0.41)cm vs(3.97±0.47)cm,the length of the postoperative penis was significantly longer than that of the preoperative penis(P<0.01).83%of those in group A(15 cases)were satisfied with the cosmic results.The length of preoperative and postoperative penis in group B were(2.07±0.53)cm vs(4.05±0.81)cm respectively,the length of the postoperative penis was significantly longer(P<0.01).Satisfaction was 87%(13 cases).The postoperative penile length between the 2 groups was not different(P> 0.05).Prepuce edema was reported to Occur in 56%and 13%in group A and group B and spontaneously disappeared within 3 months.Fat synchysis occurred in 2 of group B. Conclusions The cosmic effect of the 2 surgical approaches is similar,but circumferential approach is simpler.There is no serious complication in those receiving circumferential approach.
