BACKGROUND: Long term taking cyclosporin A(CsA)can inhibit osteoblastic differentiation and induce osteoporosis.Equol,which has greater binding affinity to estrogen receptors,can stimulate the proliferation and osteoblastic differentiation.OBJECTIVE: To investigate whether equol may protect against the proliferation and osteoblastic differentiation inhibited by CsA in mouse bone marrow mesenchymal stem cells(BMSCs)cultures and analyze signal pathway of protection.METHODS: Primary mouse BMSCs were cultured by using attachment method and assigned to five groups,which respectively treated with equol or/and CsA in the presence or absence of ICI182780,an estrogen receptor antagonist,and Nω-nitro-L-arginine methyl ester.Under an inverted microscope,morphological changes and mineralization ability of BMSCs were observed.The cell proliferation was measured by[3H]-thymidine incorporation.The osteoblastic differentiation and mineralization of extracellular matrix in BMSCs was assessed by measuring alkaline phosphatase activity and calcium deposition,respectively.Nitric oxide production in the conditioned media and cyclic guanosine monophosphata(cGMP)content in BMSCs were determined by using commercial nitric oxide and cGMP kit,respectively.RESULTS AND CONCLUSION: Equol reversed the decreased[3H]thymidine incorporation(P < 0.05),alkaline phosphatase activity(P < 0.05)and calcium deposition(P < 0.01)of CsA,which was accompanied with the changes of nitric oxide production(P < 0.01)and cGMP content(P < 0.01).The group by co-treatment with equol and CsA possessed higher cells growth density and small mineralized nodes than CsA group on day 12 under an inverted microscope.Moreover,the equol-reversed effect was abolished by ICI182780 and Nω-nitro-L-arginine methyl ester.These indicated that equol can reverse the inhibition of CsA on the proliferation and osteoblastic differentiation of mouse BMSCs through estrogen receptor/nitric oxide/cGMP signal pathway.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

Objective To study the process conditions of purifying the total flavonoids from Cacumen Platycladi by AB-8 resin. Methods Spectrophotometric method was used to detect the total flavonoids,and HPLC was used to determine quercitrin and analyze the characteristic peaks of Fingerprint. Results The purification effect was satisfactory when the concentration of original solution of the extract of Cacumen Platycladi was 0.20 g?mL-1,the loading amount was 0.375 g of Cacumen Platycladi per 1 mL of wet AB-8 resin,the adsorption velocity was 1 mL?min-1,the eluant was 70 %alcohol being 4 times as much as the resin volume,and the elution velocity was 2 mL?min-1. AB-8 resin could be used for 3 times repeatedly after being reproduced by 95 %of ethanol and 1 moL?L-1 of natrium hydroxydatum (NaOH). The remaining rate of the total flavonoids and quercitrin was over 70 %and 95 %respectively,and the remaining rate of peaks 1～3 was over 90 %. After being purified by the B-8 resin,the contents of the total flavonoids and quercitrin were raised 2.48 times and 3.29 times more than those before purification respectively. Conclusion AB-8 resin is fit for separating and purifying the total flavonoids from Cacumen Platycladi.

Objective To study the clinicopathologic features and prognosis factor of Chinese lymphoblastic lymphoma.Methods 105 LBL cases were collected.Routine HE staining,immunostaining were used to investigate the clinicopathologic features,immunotype.Results The ratio of male to female was 1.76:1 (67:38),the medial age was 13 years old (0-73 years old).53 cases (53/105,50.48 ％) primarily showed lymph node involvement,including 34 cases (34/53,64.15 ％) showed jugular node involvement;mediastinum (12/52,23.08 ％) was the most frequent extranodal involvement site.69 cases (69/105,65.71％)showed bone marrow involvement with 15 cases as the primary involvement.The expression of TdT,CD99,CD3(E),CD20,CD79a,PAX5,MPO,CD34 and CD117 was 84.76 ％ (89/105),85.00 ％ (68/80),54.37 ％ (56/103),16.67 ％ (16/96),40.00 ％ (8/20),46.67 ％ (28/60),14.29 ％ (8/56),25.00 ％ (4/16) and 0.All cases were divided in to two groups,62 cases as T-LBL (59.05 ％,62/105) and 33 cases as B-LBL (31.43 ％,33/105),with 9 cases (8.57 ％,9/105) without the expression of T or B cell marker and 1 cases with the expression of both T and B cell marker.61 cases were detected the expression of myeloid markers and 8 cases were positive.All cases were followed up.The medial survival was 36 months.The survival at 1 year,2 year and 3 year was 66.67 ％ (70/105),48.81％ (41/84) and 20.69 ％ (12/58) respectively.Age was the prognosis associated factor.The children had better progonosis than adults.Immunotype,bone marrow involovement and transplantation didn' t show prognosis indicator (P ＞ 0.05).Conclusion Most of Chinese LBL occurs in child and younger male,multi-lymphadehypertrophy and bone marrow involvement are common.LBL is an aggressive tumor.Age is the prognosis associated factor.Children have a better prognosis than the adult.

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.
