Objective To detect the expression of dead box 1(DDX1)gene in tumor tissue and pericarcino-matous tissue of clinical neuroblastoma(NB)samples,and explore the relationship between DDX1 and NB. Methods Five cases of pathological specimens in children with NB were chosen from Department of Pathology,the First Affi-liated Hospital of Xinxiang Medical University between January 2012 and December 2014. In the 5 cases,3 cases were male,2 cases were female,the age of 1 - 5 years old,average age(2. 1 ± 1. 6)years. The NB tissue and pericarcino-matous tissue(pericarcinomatous tissue was normal tissue which was at least 2 cm from the tumor tissue)of 5 children were collected and fixed in 40 g/ L formaldehyde solution. Then with the conventional dehydration,embedding,sectio-ning, dewaxing, hydration, antigen repair, add primary antibodies, secondary antibodies, diaminobenzine chromogenic. The expressions of DDX1 in tumor tissue and pericarcinomatous were observed with light microscopy and with semi - quantitative analysis.(1)Staining degree:no staining with 0 score;light staining with 1 score;medium staining with 2 scores;deeply staining with 3 scores.(2)Positive cells proportion:positive cells proportion ﹤ 10% with 0 score;positive cells proportion within 10% - 30% with 1 score;positive cells proportion within 31% - 60% with 2 scores;positive cells proportion ﹥ 61% with 3 scores. Final scores were a half of the sum of staining degree score and positive cells proportion score,final score within 0 -1. 0 with - ,1. 1 -2. 0 with + ,2. 1 - 3. 0 with + + ,3. 1 -5. 0 with + + + . Results DDX1 were expressed in NB and pericarcinomatous tissues,but visible DDX1 positive staining number more and deeper in NB,DDX1 positive staining number less and light in pericarcinomatous tissues. Five cases of pericarcinomatous tissues immunohistochemical semi - quantitative score were negative and final scores were 1. 0 score or less,the mean value was 0. 5 score. NB immunohistochemical semi - quantitative score were+or + +and final scores were 1. 5 score or higher,the mean value was 1. 8 scores,the expressions of DDX1 were sig-nificantly higher in NB than the pericarcinomatous tissues. Conclusions DDX1 is highly expressed in NB,which may contribute to the development of NB. This suggest DDX1 may serve as an oncogene and play a catalytic role in the de-velopment of NB,which provides a clinical evidence for the follow - up study.

Objective To explore the influence of icotinib in the apoptosis of the human salivary adenoid cystic carcinoma cells ACC-M, and to clarify the mechanism of icotinib for the treatment of salivary adenoid cystic carcinoma.Methods The ACC-M cells were randomly divided into control group,2,4,8μmo1·L-1 icotinib groups,p38-MAPK inhibitor SB203580 (20μmol· L-1 )group,SB203580 (20 μmol· L-1 )+4μmo1 · L-1 icotinib group;the cells were collected 4 h after treatment.The viability of ACC-M cells was measured by MTT assay.The apoptosis of ACC-M cells was assessed by caspase-3 activity kit. The expression of p-p38-MAPK protein was determined by Western blotting analysis.Results Compared with control group,the inhibitory rates of growth of the ACC-M cells in icotinib groups were significantly decreased (P<0.05 ), and the activities of caspase-3 were increased (P<0.05),and the expression levels of p-p38-MAPK were significantly increased (P<0.05).Compared with 4μmo1·L-1 icotinib group,the expression level of p-p38-MAPK in SB203580+icotinib group were decreased (P < 0.05 ), and the activity of caspase-3 was decreased dramatically (P < 0.05 ). Conclusion Icotinib may induce the apoptosis of ACC-M cells through the activation of p38-MAPK signaling pathway.

OBJECTIVETo evaluate the correlation between MicroRNA-191 (miR-191) and T lymphoblastic leukemia/lymphoma (T-ALL/LBL) to probe its underlying molecular mechanism.

METHODSThe expression of miR-191 was examined by real-time PCR (RT-PCR) in 20 T-ALL/LBL tissue samples and 20 lymphoid reactive hyperplasia (LRH) tissue samples. The correlation between miR-191 and the clinicopathological feature of T-ALL/LBL was analyzed. Antisense miR-191 lentiviral vectors was constructed and transfected into T-ALL/LBL Jukat cells. After transfection, the expression of miR-191 was examined by RT-PCR. The cell activity was evaluated by CCK-8 asssy. The cell cycle and apoptosis were determined by flow cytometry.

RESULTSCompared with LRH samples, the results of RT-PCR showed significant upregulation of miR-191 in 20 T-ALL/LBL tissue samples (1.875±0.079 vs 1.000, P<0.05). The expression level of miR-191 was negatively associated with prognosis. Compared with LV-NC-GFP and control groups, the expression of miR-191 significantly decreased after transfection of antisense miR-191 lentiviral vectors (0.578±0.012 vs 1.011±0.053 and 1.000, P<0.05), the percentages of apoptotic cells and the cell in G0/G1 phase significantly increased (P<0.05).

CONCLUSIONSmiR-191 might play a significant role in the development of T-ALL/LBL, implicating a new target for therapy.

Objective To compare the efficacy and safety of Iamivudine-interferon sequential therapy and lamivudine monotherapy in HBeAg-positive chronic hepatitis B (CHB) patients.MethodsA total of 172 patients with HBeAg-positive CHB were randomized to sequential group (n=83) or lamivudine group (n=89).Sequential group were administrated with lamivudine 100 mg/d and 5 million units interferon alpha 2b subcutaneous injection every other day for 24 weeks were added since week 25 of treatment.Lamivudine group were administrated with lamivudine 100 mg/d for 48 weeks.All subjects were followed up for 24 weeks after drug withdrawal.Measurement data with homogeneity of variance were analyzed by using t test and data with heterogeneity of variance were analyzed by using rank sum test.The comparison of rates was done by chi square test or Fisher exact test.ResultsThe baseline hepatitis B virus (HBV) DNA levels of patients in sequential group and lamivudine group were (7.8±1.0) and (7.9±1.1) lg copy/mL,respectively (P＞0.05),and the baseline alanine aminotransferase (ALT) levels were (210.5 ± 150.1 ) and (211.9 ± 160.9) U/L,respectively (P＞0.05).At the end of treatment,higher ALT levels [(78.4±146.1) vs (36.1±32.4) U/L,P＜0.05)] and HBV DNA levels [(4.5±1.5) vs (3.8±1.3) lg copy/mL,P＜0.05)] levels,lower response rates (65.8％ vs 83.5％,P＜0.05),and similar HBeAg loss rates (31.6％ vs 22.2％,P＞0.05) and HBeAg seroconversion rates (27.6％ vs 16.0％,P＞0.05) were found in sequential group compared with lamivudine group.At the end of follow-up,higher ALT levels [(126.0±143.1) vs (82.7±83.0) U/L,P＜0.05)],similar HBV DNA levels [(5.3±1.5) vs (5.0±1.5) lg copy/mL,P＞0.05)],similar HBeAg loss rates (25.0％ vs 32.3％,P＞0.05) and HBeAg seroconversion rates (25.0 ％ vs 26.2 ％,P＞0.05) were found in sequential group compared with lamivudine group.YMDD motif mutation rate in sequential group was lower than lamivudine group at week 48 of treatment (10.5％ vs 26.9％,P＜0.05).ConclusionsLamivudine-interferon sequential therapy and lamivudine monotherapy are both effective in HBeAg-positive CHB patients,while HBV mutations are reduced in patients with sequential therapy.

Objective:To explore the influential factors for hospitalization costs regarding the final phase of malignant tumor patients in Shanghai,and to explore the relevant policy for reasonable control of hospitalization costs.Methods:A total of 10 065 patients with malignant tumors were enrolled in this study.The multiple linear regression analysis was used to seek the determinants for hospitalization cost of malignant tumor patients during the final phase.Results:The median length of hospital stay was 43 days for the patients,with an average age of (70.73±12.87) years.Among them 61.66％ of hospitalized patients were male and the median hospitalization cost of malignancy was 55 447.84 yuan.Hospitalization cost showed the linear regression relationship with type of health care,hospital level,hospital types,tumor types,length of hospital stay,surgery,age,gender,and time from hospital admission to death.Conclusion:Proximity to death in malignant tumor patients is an important factor for the hospitalization cost.Medical resources should be allocated rationally,and the comprehensive measures should be taken to control the cost reasonably.

Objective To investigate the significance of long non-coding RNA MALAT1 expression in osteosarcoma,and the potential mechanism by which MALAT1 promotes tumor metastasis.Methods Twenty cases of osteosarcoma in the First Affiliated Hospital of Xinxiang Medical University and Ping Ding Shan First People 's Hospital were collected from January 2014 to December 2015.The expression of MALAT1 in osteosarcoma tissue and paired adjacent noncancerous tissue were analyzed by qRT-PCR.Correlation of MALAT1 expression in osteosarcoma with clinical pathologic features was performed by the Mann-Whitney U test.U-2OS cells were transfected with lenti-virus carrying MALAT1-shRNA and nonspecific shRNA (LV-vector).The expression of MALAT1 was detected by qRT-PCR.The cell activity was evaluated by MTT asssy.The impact of MALAT1-shRNA on invasion in U-2OS cells were determined by transwell migration assay.The expression of Wnt/β-catenin signal pathway related proteins were detected by Immunofluorescence stain and Western blot.Results The expression level of MALAT1 in osteosarcoma tissue was higher than that in paired adjacent noncancerous tissue and correlated significantly with nodal and pulmonary metastasis(P ＜ 0.01).MTT assay showed that knockdown of MALAT1 with lenti virus-MALAT1 shRNA inhibited the growth of U-2OS cells,along with marked decrease of invasive ability of U-2OS cells in the transwell migration assay.By immunofluorescence stain and Western blot assay,MALAT1 significantly reduced the expression of β-catenin,MMP7,and c-MYC in U-2OS cells.Conclusions The expression of MALAT1 is high in osteosarcoma and correlates with tumor metastasis.MALAT1 promotes invasion and metastasis of osteosarcoma cells likely thought the Wnt/β-catenin signal pathway.

Objective:To explore the related factors of thrombocytopenia (TCP) occurrence in patients with cirrhosis.Methods:A cross-sectional study was conducted. Inpatients with an initial diagnosis of cirrhosis at Peking University First Hospital from January 1, 2010 to December 31, 2020 were included. Clinical data such as demographic characteristics, etiology of cirrhosis, complications of cirrhosis, laboratory indicators, Child-Pugh grade, invasive procedures, and mortality during hospitalization were collected. A logistic regression model was used to explore the related factors of TCP occurrence in patients with cirrhosis. Categorical variables were compared by the χ2 test. The inter-group comparison was performed using continuous variables, a t-test, one-way analysis of variance (ANOVA), or a nonparametric test. Results:There were a total of 2 592 cases of cirrhosis. 75 cases with incomplete clinical data were excluded. 2 517 cases were included for analysis. The median age was 58 (50, 67) years. Males accounted for 64%. 1 435 cases (57.0%) developed TCP, and 434 cases (17.2%) had grade 3-4 TCP. Gender, primary biliary cholangitis (PBC), primary sclerosing cholangitis (PSC), and concomitant esophagogastric varices (EGV) were the major factors associated with TCP. Females were more prone to combine with TCP ( OR=1.32, 95% CI: 1.12-1.56, P=0.001). Patients combined with EGV ( OR=3.09, 95% CI: 2.63-3.65, P<0.001) were more prone to develop TCP, which was associated with the increased incidence of hypersplenism ( P<0.001). Patients with PBC ( OR=0.64, 95% CI: 0.50-0.82, P<0.001) and PSC ( OR=0.23, 95% CI: 0.06-0.65, P=0.010) were less prone to develop TCP, which was due to the shorter prothrombin time and better coagulation function of PBC patients ( P<0.001), and the lower proportion of hypersplenism in combined PSC patients ( P=0.004). Patients with TCP and grade 3-4 TCP had a higher rate of hemostatic procedures ( P<0.05), but a lower rate of liver biopsy ( P<0.05). Patients with grade 3-4 TCP had a higher nosocomial mortality rate compared to those without ( P=0.004). Conclusion:TCP is common in patients with cirrhosis. However, TCP occurrence is higher in female patients with EGV and lower in patients combined with PBC and PSC. TCP affects invasive procedures and is associated with adverse outcomes.

OBJECTIVETo study the clinicopathological characteristics and prognostic factors in Chinese patients with primary intestinal non-Hodgkin's lymphomas (PINHL).

METHODSThe clinical symptoms, pathological features, diagnostic and prognostic factors of 273 cases diagnosed with PINHL from our center were analyzed.

RESULTSAmong 273 cases, 189 were male and 84 female, the male to female ratio was 2.3:1. The age of patients ranged from 2 to 85 years old with the median age of 46. The most frequent site of the lesions was ileocecus (n=83, 30.4%). The clinical symptoms of PINHL were unspecific with abdominal mass frequently seen in B-cell lymphoma, and perforation, hypogastric pain and "B" symptoms more common in T-cell lymphoma. Endoscopic biopsy diagnosis rate was 90.3%. Of 273 cases, B-cell lymphoma (n=232, 85.0%) dominated PINHL with the most common subtype of diffuse large B-cell lymphoma-not otherwise specified (DLBCL-NOS) (n=132, 48.4%), while the T-cell lymphoma (n=41, 15.0%) were much less seen with the most common subtype of enteropathy-associated T-cell lymphoma (EATL) (n=15, 36.6%). There were 245 cases were followed up, including 206 cases of B-cell lymphoma and 39 cases of T-cell lymphoma, it was found that the prognosis of B-cell lymphoma is much better than that of T-cell lymphoma (P<0.05). Operation had no significant effect for the overall survival rate. But for patients with aggressive lymphoma, operation can improve the survival rate.

CONCLUSIONIt indicates that PINHL often occurs as B cell type, DLBCL-NOS is the most common histological type. Ileocecus is the most common site involved and enteroscope biopsy is a good method of diagnosis. Compared with T-cell lymphoma, B-cell lymphoma has different clinical manifestations and a better prognosis. Patients with aggressive lymphoma can benefit from operation.
