Duchenne muscular dystrophy is the most prevalent muscular dystrophy caused by dystrophin gene mutations. In the central nervous systerm, there are at least six dystrophin isoforms, in which Dp140 is closely associated with cognitive impairment. This paper re-viewed the discovery, structure, gene location, detection methods and function of Dp140.

Objective To explore the expression of ankyrin-repeat SOCS box containing protein 2 (ASB2)and Janus kinase 3 (Jak3)mRNA in bone marrow plasma mononuclear cells of patients with acute lymphoblastic leukemia (ALL)and discuss the correlation of them.Methods Bone marrow plasma was collected from 48 patients of newly diagnosed ALL (37 cases B-ALL and 11 cases T-ALL)and 34 non leukemia patients (control group),respectively.Expression levels of ASB2 and Jak3 mRNA were detected by real-time quantitative PCR.Results The expression of ASB2 mRNA in B-ALL and T-ALL were significantly different compared to control group (t =14.2,P <0.01;t =15.2,P <0.01),which were 68.5,32.7 folded more than control group,respectively.Moreover,the expression level of Jak3 mRNA in B-ALL group and T-ALL group were 2 336.1 and 7 131.5 folded more than control group (t =37.3,P <0.01;t =37.6,P <0.01). At last,the expression of ASB2 and Jak3 gene was positive correlation (r =0.523,P <0.001).Conclusion ASB2 and Jak3 are expressed abnormally in ALL patients and the correlation of them is positive.ASB2 and Jak3 may be related to the proliferation and differentiation in leukemia cells.

Objective:To study on effect of Danshao Huaxian Capsule on proliferation of activated hepatic stellate cells(HSCs)in vivo and in vitro.Methods:(1)In vitro experiment:57 male Wistar rats were divided into a normal group,a model group and a treatment group.The rats of model group and treatment group were made hepatic fibrosis model with complex stimulation of CCl_4,drinking alcohol,high lipids and low protein diet for 8 weeks.The treatment group were treated for 8 weeks with intragastric perfusion of Danshao Huaxian Capsule,1g/kg.At the end of experiment,a part of the rats were used for detection of hepatic functions and hepatic fibrosis degrees,and another part of the rats were used to separate HSCs.Cell cycle percentage was detected with flow cytometry.(2)In vivo experiment:prepare Danshao Huaxian Capsule serum of the rat;separate cultured HSCs of the rat and divide into calf serum group,normal rat serum group and Danshao Huaxian Capsule serum group.5%,10% and 20% of the above serum was respectively added into the cultured HSCs.Primary HSCs proliferation was detected with MTT method.Results:(1)In vitro experiment:The hepatic function,hepatic fibrosis level and HSCs proliferation reduced significantly.(2)In vivo experiment: Danshao Huaxian Capstde serum group could significantly inhibit proliferation of HSCs as compared with calf serum group and normal rat serum group at the same content.The action showed dose-dependence.Conclusion:Danshao Huaxian Capsule can obviously inhibit proliferation of HSCs in vivo and in vitro.

Objective:To investigate the correlation between root and root canal diameter of maxillary central incisors and age by cone-beam computed tomography(CBCT).Methods:CBCT images of 420 cases of Chinese Han population were divided into 7 age groups as follows:1 5 -24,25 -34,35 -44,45 -54,55 -64,65 -74 and 75 -84(n =60).Root diameter and root canal diameter of maxillary central incisors at the 3 /4 level from the cemenal-enamel junction(CEJ)to root apical were measured.Linear-regression a-nalysis was used to analyze the correlation between root and root canal diameter of the teeth and age,T-test was used to examine the gender difference.Results:Mean root diameter(mm)of the teeth in males and females were 5.81 ±0.445 and 5.53 ±0.489(P <0.05),mean root canal diameter(mm)1 .20 ±0.396 and 0.96 ±0.236(P <0.05),mean of the ratio of root canal diameter and root diameter of the teeth 0.21 ±0.072 and 0.1 7 ±0.043(P <0.05)respectively.There were negative correlations between the ratio of root canal diameter and root diameter of the teeth with age (R2 =0.576,P <0.05).Conclusion:The ratio of root canal diameter and root diameter of maxillary central incisors is negitively correlated with age in Chinese Han population.The decrease of root canal diame-ter in males is more significant than that in females.

Objective To study the clinical characteristics, treatment methods and prognosis of primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL). Methods The clinical data of 40 patients with PGI- DLBCL were retrospectively analyzed. All the cases had received surgery treatment. Results In 40 patients with PGI-DLBCL, the major clinical presentation included abdominal pain in 15 cases (37.5%), abdominal mass in 6 cases (15.0%), abdominal discomfort in 5 cases (12.5%), abdominal distension in 5 cases (12.5%), and hematemesis in 5 cases (12.5%). Fifteen cases were misdiagnosed as gastric cancer, 5 cases as colon cancer, and 4 cases as digestive tract ulcer. The misdiagnosis rate was 60.0% (24/40). The survival rates of 1- , 2- and 3- year were 62.3%, 57.5% and 52.6%. The univariate analyses result showed that the clinical stage, international prognosis index (IPI) and treatment method were associated with survival rate (P<0.01), but the gender, age and disease distribution were not associated with survival rate (P > 0.05). The 3-year survival rate of clinical stage Ⅰ - Ⅱ was significantly higher than clinical stageⅢ-Ⅳ(68.0%vs. 13.3%), the 3-year survival rate of IPI 0-2 scores was significantly higher than 3 - 5 scores (66.7% vs. 7.6%), and the 3- year survival rate of surgery combined with postoperative chemotherapy was significantly higher than simple surgery (75.0%vs. 20.0%), there were statistical differences (P<0.01). Conclusions The patients with PGI- DLBCL have no obvious clinical manifestions and a higher misdiagnosed rate. Modified IPI, clinical stage and surgery combined with postoperative chemotherapy are the influencing factors of prognosis.

Objective To investigate the cognitive condition in patients with Duchenne muscular dystrophy (DMD). Methods Wechsler Intelligence Scale for Children IV (WISC-IV) was administered for 127 DMD patients aged 6~14 years from April, 2013 to December, 2015. The verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ) and full-scale intelligence quotient (FSIQ) scores were analyzed. Results The FSIQ, VIQ and PIQ were (93.2±18.6), (91.5±18.9), and (96.6±19.5), respectively, which were lower than 100 in normal population (P<0.001), and higher than that of patients abroad in the previous studies (P<0.001). There were 13 patients (10.24%) whose scores of FSIQ were less than 70. The VIQ-PIQ discrepancy score was (-5.0 ± 16.6). Conclusion About 1/10 of Chinese DMD pa-tients impaire in cognitive function, which is significantly lower than that abroad. VIQ is more affected than PIQ.
