Objective:To assess the efficacy of acupuncture plus Methadone in treating heroin withdrawal syndrome.Methods:According to the requirements of evidence-based medicine, the inclusion criteria, exclusion criteria and retrieval strategy were set for original documents. Randomized controlled trials (RCTs) involving acupuncture plus Methadone in treating heroin withdrawal syndrome were retrieved from China National Knowledge Infrastructure Database (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chinese Biomedical Literature Database (CBM), Chongqing VIP Database (CQVIP), PubMed, Cochrane Library and EMBASE. According to the Cochrane Handbook for Systematic Reviews of Interventions, each included trial was assessed strictly including risk of bias and quality evaluation. Meta-analysis and descriptive-analysis were conducted using the RevMan 5.3 software.Results:A total of 8 trials involving 931 patients were included. Meta-analysis showed that there was no statistical significance [RR=1.05; 95%CI (0.99, 1.11);P=0.11] in comparing total effective rate between the acupuncture plus Methadone and Methadone alone; the cure rate of acupuncture plus Methadone was higher than that of Methadone alone [RR=1.45; 95%CI (1.19, 1.78);P=0.0003]; the relapse rate of the acupuncture plus Methadone was lower [RR=0.691; 95%CI (0.60, 0.80);P<0.00001]. On the basis of these results, the method recommended by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was taken to evaluate the quality of the evidence. It showed that the level of the evidence was low and it was weakly recommended.Conclusion:According to the included trials, acupuncture plus Methadone in treating heroin withdrawal syndrome is more effective and better than Methadone alone, but it still needs more high-quality, large sample, and polycentric researches to confirm it.

ObjectiveTo systematically assess the efficacy of acupuncture and moxibustion plus cognitive rehabilitation training in treating post-stroke cognitive disorder.MethodA computer searched CNKI, CBM, VIP, WANFANG DATA, and Pubmed and Cochrane Library for randomized controlled trials (RCT) of acupuncture and moxibustion plus cognitive rehabilitation training for the treatment of post-stroke cognitive disorder. The reference literature in the included literature was also retrieved. Retrieval time limit for both of them was from Jan. 1st 1990 to Jan. 1st 2015. Two reviewers independently selected the trials, extracted the data and assessed the quality of methodology. Meta analysis was then performed using RevMan 5.3 software.ResultEleven trials with a total of 789 subjectswere finally included. The results of Meta analysis showed that the following aspects were better in acupuncture plus cognitive rehabilitation training than in cognitive rehabilitation training or medication alone and there were statistically significant differences: the total efficacy rate [RR=1.58, 95%CI(1.10,2.26),P=0.01], the MMSE score [MD=2.64, 95%CI(1.78, 3.50),P<0.00001], P300 latency [MD=﹣18.46, 95%CI(﹣30.51,﹣6.41),P=0.003], P300 amplitude [MD=1.23, 95%CI(0.82, 1.63),P<0.00001] and activities of daily living (ADL) [SMD=0.52, 95% CI(0.31, 0.73),P<0.00001]. Based on the results of a systematical review, thequality of evidence was assessed using GRADE system recommended classification method. The results showed that the level of evidence was low and the strength of recommendations was weak.ConclusionThe results of Meta analysis showed that the therapeuticeffect was better in acupuncture and moxibustion plus cognitive rehabilitation training than in cognitive rehabilitation training or medication alone. Because of low quality of all the original literature, high-quality, multicenter and large-sample randomized blind controlled trials are still needed for validation.

Objective: To investigate the pathological types and prognostic factors of primary lymphoma of breast (PLB). Methods: The clinical pathological data of 115 cases of PLB during October 2006 to October 2016 were retrospectively analyzed, and the basic clinical and pathological data, pathology types and the immunohistochemical slides by EliVision two-step method for staining were summarized. Results: Almost all the patients were women (113/115), and the median age was 52 years old (range: 27 to 81 years old). The main symptom was painless progressive mass in breast. Ten cases (8.7%) showed B symptoms. The masses were mainly confined to the unilateral breast (80.9%, 93/115), of which 22 cases showed axillary lymph nodes enlargement in the same side. The average diameter of masses was 3.0 cm (range from 0.5 to 9.0 cm). There is no differences between the sides (left or right). Pathologically, 106 cases (92.2%) were mature non-Hodgkin′s B-cell lymphomas, of which there were mainly diffuse large B cell lymphoma (DLBCL, 64.3%) and mucosa associated lymphoid tissue (MALT) extranodal marginal lymphoma (17.4%). Five cases (4.4%) were mature T/NK cell lymphomas, including extranodal nasal NK/T cell lymphoma (1.7%), peripheral T-cell lymphoma non-specific type (0.9%), subcutaneous panniculitis-like T cells lymphoma (0.9%) and undivided (0.9%). Four cases were lymphoblastic lymphoma. According to Ann Arbor staging criteria, 93 cases were stage ⅠE (6 cases were stage ⅠEB), 22 cases were stage ⅡE (4 cases were stage ⅡEB). Ninety-two cases were followed 1 to 122 months (median: 36 months). The five-year overall survival rate was 85.3%, and 13 patients dead. B symptom was one of the factors that affect the prognosis (P<0.05), but the pathological type has no relationship with the prognosis (P>0.05). Conclusions PLB is relatively rare, the main clinical manifestation is painless mass, which is difficult to distinguish with breast carcinoma. The most common type is DLBCL, followed by MALT lymphoma, while T cell lymphoma is rarely seen. PLB is early stage tumor with good prognosis, while patients with B symptom turn out to suffer worse prognosis.

Objective To investigate the clinicopathological features of long?term tumor?free survival in patients with untreated primary diffuse large B?cell lymphoma (DLBCL) of the tonsil. Methods The study included 80 consultation cases of primary tonsillar DLBCL from April 2006 to July 2017 in the Department of Pathology, Beijing Friendship Hospital, Capital Medical University. The patients were divided into two groups: experimental groups of 10 untreated patients with long?term tumor?free survival, and 70 patients who had been treated (control group). The clinical data, histopathological features, immunohistochemical staining, and molecular biology test results of the patients were analyzed retrospectively. Results Patients who had long?term tumor?free survival with untreated primary diffuse large B?cell lymphoma had the disease mostly confined to the tonsil. Biopsy showed that the tonsil structure was only partially effaced and the lesions were relatively "fresh". EBER and FISH test for t (14;18) results were negative. Gene rearrangement detection showed monoclonality. There was statistically significant difference between the age, bcl?2 expression, CMYC protein expression and co?expression of CMYC and bcl?2 between the untreated group and the treated group(P<0.05). Patient gender, tumor site, histological type and clinical stage showed no difference between the untreated group and the treated group (P>0.05);The median overall survival of the untreated group and treated group was 81 months and 20 months, respectively, and the difference was not statistically significant (P>0.05).In patients younger than 40 years of age, the untreated group had a statistically significant difference in primary site and CMYC protein expression compared with the treated group (P<0.05), and there was no statistical significance in other aspects. Conclusions Long?term tumor?free survival patients with untreated tonsillar primary DLBCL have relatively unique clinical characteristics. There is no significant difference in the prognosis between the untreated and treated groups, indicating radiotherapy and chemotherapy may not be required and therefore, avoiding related side effects.

Objective: To analyze clinical, pathological, molecular and genetic characteristics of Burkitt-like lymphoma with chromosome 11q aberration. Methods: A case of Burkitt-like lymphoma with 11q aberration was presented at Beijing Friendship Hospital in November 2016 with detailed clinicopathological features, immunophenotypes, Epstein-Barr virus(EBV) status and molecular genetic characteristics. Results: The patient was a 38-year-old man presenting with the cervical lymphadenopathy. In morphology, the tumor had the similar characteristics of Burkitt lymphoma, including diffuse infiltration of medium to large lymphoid cells, and presence of"starry sky"phenomenon. Immunophenotypically, the tumor cells were positive for CD20, CD10, bcl-6, but negative for bcl-2. MUM-1 showed weak and patchy positivity. Ki-67 index was more than 95%. C-MYC expression was seen in about 50% of tumor cells. EBV in situ hybridization was negative. IgH and IgK genes were clonally rearranged.Fluorescence in situ hybrization detection using MYC break probe was negative but ATM gene amplification on chromosome 11q was detected. The patient did not receive any chemotherapy or radiotherapy and had not recurrence during the 10 months follow-up. Conclusion Burkitt-like lymphoma with chromosome 11q aberration has similar clinical, morphological and immunological characteristics to classic Burkitt′s lymphoma.

Objective: To investigate clinicopathological features and prognosis of tonsillar mantle cell lymphoma(TMCL). Methods: Clinical data of 25 patients with TMCL at Beijing Friendship Hospital, Capital Medical University from 2002 to 2016 were included. All the cases were reviewed microscopically. Various immunohistochemical stains were performed using the MaxVision two-step method. IgH/CCND1 gene fusion was detected by fluorescent in situ hybridization(FISH). Additionally, randomly selected 40 cases of non-tonsil MCL of the same period were compared. Results: Among all mantle cell lymphomas (MCL), TMCL accounted for 5.6%(25/449). The median age of the patients was 60 years(range: 44-82 years) with a M∶F ratio of 5.3 to 1.0. The main symptoms were sore throat and foreign body sensation and patients usually presented with enlargement or mass of tonsil. At the early stage of the disease, 18 cases(72.0%) were clinically misdiagnosed as tonsillitis. Lymph node involvement was present in 76.0%(19/25) of the patients. There were 4 cases(16.0%)with current splenic involvement, 11 cases(44.0%) with pharyngeal focal recidivism, and 3 cases(12.0%) with involvement of other non-lymphoid organs. Morphologically, tonsillar architectures were effaced at various degrees. Eighteen MCL cases showed classical type and 7 cases were blastoid variant. All tumors were positive for CD20 and cyclin D1. 92.0%(23/25) tumors showed weakly positive or positive expression for CD5. FISH test that IgH/CCND1 gene fusion was positive in two CD5 negative classical cases. 18 patients(72.0%) had a median follow-up time of 26 months(range: 6-81 months). The difference of survival rate between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients was not statistically significant(P>0.05). Compared with NTMCL, TMCL was found to have higher proportion of stage Ⅰ-Ⅱ disease (χ²=12.789, P<0.01), lower the proportion of non-lymphatic organ involvement (χ²=8.125, P<0.01), and better prognosis (χ²=4.351, P=0.037). Conclusion The incidence of TMCL is low and prone to be misdiagnosed as tonsillitis. Patients with TMCL are more likely at stage Ⅰ-Ⅱ at presentation and the prognosis is better than that of NTMCL.

Objective: To determine the cut-off values of Ki-67 labeling index (LI) in the histological grading of follicular lymphoma (FL). Methods: Clinicopathological data of 350 FL patients diagnosed at Beijing Friendship Hospital from June 2014 to January 2016 were analyzed retrospectively by quantitative evaluation and statistical analysis of Ki-67 LI. Results: Of the 350 patients with FL, the male and female ratio was 1.1 and the average age was (50.2±14.0) years with a median age of 51 years (range 4 to 82 years). The tumors were graded as grade Ⅰ-Ⅱ in 215 cases (61.4%), grade Ⅲ A in 105 cases (30.0%), and grade Ⅲ B in 30 cases (8.6%). The average Ki-67 values were (22.8%±8.3%) for the FL low (grade Ⅰ-Ⅱ) and (50.4%±10.7%) for high grade (Ⅲ A and Ⅲ B) and were statistically significant by Mann Whitney U test (P<0.01). Receiver operated characteristic curve analysis showed that the best diagnostic cut-off value of low grade FL was 35% (sensitivity of 96.3% and specificity of 93.3%) with the largest area under curve (AUC=0.990, P<0.01, 95%CI for 0.982-0.998). According to the analysis of four lattice diagnostic tests, Ki-67 LI >40% was an important factor (χ²=230.733, P<0.01) in predicting high grade FL. When the cut-off value of Ki-67 LI was set at 40%, high grade LF could be diagnosed with the greatest sensitivity (98.1%) and specificity (87.7%). Moreover, a significant correlation between the Ki-67 LI and the pathological grade of FL (r=0.836, P<0.01) was observed. Conclusions Ki-67 LI of below a cut-off value of 35% is a reliable indicator of low grade FL.Ki-67 over 40% is consistent with high grade FL. These Ki-67 cut-off values may serveas an important auxiliary indicator in the grading of FL.

Objective: To investigate the clinicopathologic features and prognosis of gastrointestinal mantle cell lymphoma (GI-MCL). Methods: Clinical data of 38 GI-MCL patients diagnosed at Beijing Friendship Hospital from January 2002 to January 2016 were retrospectively reviewed morphologically and immunophenotypically. IgH/CCND1 gene fusion was assessed by fluorescent in situ hybridization (FISH). For comparison, 60 cases of non-GI-MCL were randomly selected to extract the differences inclinicopathological features and patient survival between the two groups. Results: Of 38 patients with GI-MCL, the median age was 62 years (range: 35-78 years, 23 males and 15 females), of which patients of 60 years of age or older accounted for 55.3%. Patients with clinical course of less than 6 months accounted for 81.1%(30/37). The main symptoms included abdominal pain, diarrhea, anorexia and hematochezia. Those with B symptoms accounted for 32.4%(12/37). The tumor most often involved lleocecal region (57.9%, 22/38), followed by rectum (36.8%, 14/38) and sigmoid colon (28.9%, 11/37), and the stomach accounted for 18.4%(14/38). Endoscopic polypoid lesions were found in 33 cases (86.8%, 33/38), of which 22 cases (66.7%, 22/33) were multiple. Five cases (13.2%, 5/38) presented with local protuberant neoplasm. According to Ann Arbor staging, 3 cases (7.9%, 3/38) were at stage Ⅰ, 4 cases (10.5%, 4/38) were at stage Ⅱ, and 31 cases (81.6%, 31/38) were at stage Ⅳ. The number of patients with tumor involvement of abdominal and retroperitoneal lymph nodes accounted for 45.7%(16/35), including 41.7%(15/36) involving the superficial lymph node, 17.1%(6/35) involving extranodal sites, and 23.5%(8/34) having splenomegaly. All of the 38 cases were classic MCL, and the tumor was composed of uniform lymphoid cells and effacing normal mucosal structure. All tumors were positive for CD20 and CD5. 97.4% (37/38) tumors were positive for cyclin D1, and 92.0% (23/25) tumors were positive for SOX11. FISH test was positive in 1 case of cyclin D1 negative tumor. Twenty-eight patients (73.7%) had a median follow-up of 25.0 months (range: 3-79 months). The 3-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ of patients were 80.0% and 69.1%, respectively (P> 0.05). The 3-year survival rate for GI-MCL and non-GI-MCL patients were 71.7% and 72.5%, respectively (P>0.05). Single factor analysis showed that age of >60 years and splenomegaly were correlated with a worse overall survival rate (P<0.05). Conclusions Gastrointestinal malaise is the most common presenting symptom in GI-MCL patients. GI-MCL more commonly involves colorectum with more frequent multiple polypoid lesions. Patients of age >60 years and with splenomegaly have poor prognosis. There is no difference in the prognosis between GI-MCL and non-GI-MCL patients.
