Objective To evaluate the acute side effects and efficacy of three dimensional conformal radiotherapy (3D-CRT) combined with gemcitabine chemotherapy for locally advanced non-small cell lung cancer (NSCLC). Methods From January 2006 to December 2007, 90 cases with advanced NSCLC were divided into two groups, treatment group of 45 patients were tre.ated with 3D-CRT and gemcitabine, control group of 45 patients were treated with gemcitabine and conventional radiotherapy. Chemotherapy consisted of intravenously gemeitabine 350 mg/m2 on day 1, 8, 15, 22, 29, 36. Radioactive source was used with X ray of 6 MV or 15 MV. Irradiatial target area were lung site and mediastinal node. Results The complete remission (CR)and remission rate(RR) in centrol group were 5 cases (11.1%) and 28 cases(62.2%), but in treatment group were 13 cases (28.9%) and 38 cases (84.4%), respectively. The difference of response rate in two groups was significant(P < 0.05). The rate of acute radiation-induced pneumonifis and esophagitis in control group (28.9%, 35.6%)were higher than those in treatment group (11.1%, 17.8%), there were significant difference between two groups (P < 0.05). Conclusions Concurrent application of gemcitabine and 3D-CRT can improve the RR for locally advanced NSCLC, and the acute toxicity are lower than those of gemcitabine and conventional radiotherapy. The clinical study is needed, but the late effect shoud be followed.

Activity of IL-1 produced by peripheral blood monocytes stimulated with lipopolysaccharide in vitro was detected from 17 acute cases, 14 chronic cases and 19 advanced cases of schistosomiasis japonica. It was found that the level of IL-1 was significantly increased and positively related to the body tempereture in the group with acute schistosomiasis. The activity of IL-1 was statistically reduced in the chronic and advanced groups, especially in the latter. After inhibiting the synthesis of prostaglandin with indomethacin, the level of IL-1 was significantly increased in three groups of patients, but no apparent change in the normal contro group. The results indicate that IL-1 may play an important role in inducing the inflammatory reaction in patients with acute schistosomiasis japonica and in the immunoregulation in the chronic stage. The changes of IL-1 activity in patients with schistosomiasis japonica may be closely related to prostaglandin.

Objective:
To evaluate the prognostic value of lymphocyte-to-monocyte ratio (LMR) in angioimmunoblastic T cell lymphoma (AITL).
Methods:
Data of 64 patients diagnosed as AITL at the First Affiliated Hospital of Nanjing Medical University between June 2009 and July 2017, were analyzed retrospectively. Receiver Operator Characteristic (ROC) curve was used to calculate the cutoff value of LMR to divide this cohort of patients into high and low LMR groups. Characteristics between groups were compared by Pearson Chi-square or Fisher exact tests. Kaplan-Meier method and Cox regression were performed to probe prognostic factors associated with progression-free survival (PFS) and overall survival (OS).
Results:
A total of 64 cases [39 cases male and 25 ones female with the median age of 63 (29-89) years old] were enrolled. The cutoff value of LMR was 3.07. Patients with low LMR showed inferior PFS (9 months

OBJECTIVE:
To analyze the correlation between the mutational status of immunoglobulin heavy chain variable (IGHV) gene with the prognosis of patients with Waldenström macroglobulinemia (WM).
METHODS:
Immunoglobulin heavy chain gene (IGH) clonotypic sequence analysis was carried out to assess the mutational status of IGHV in the blood and/or bone marrow samples from 44 WM patients. The usage characteristics of IGHV-IGHD-IGHJ gene was explored.
RESULTS:
The most common IGHV subgroup was IGHV3, which was similar to the data from the Institute of Hematology of Chinese Academy of Medical Science. IGHV3-23 (20.45% vs. 15.44%) and IGHV3-74 (11.36% vs. 7.35%) were the main fragments used, which was followed by IGHV4 gene family (15.91% vs. 24.26%). However, no significant correlation was found between the IGHV4 usage and the prognosis of the patients. Should 98% be taken as the cut-off value for the IGHV mutation status, only 5 patients had no IGHV variant, and there was no correlation with the prognosis. Based on the X-tile analysis, 92.6% was re-selected as the cut-off value for the IGHV variant status in such patients. LDH was increased in 26 patients (59.1%) without IGHV variant (P < 0.05), whilst progression-free survival (P < 0.05) and overall survival (P < 0.05) were significantly shorter compared with those with IGHV variants.
CONCLUSION
The usage characteristics of IGHV-IGHD-IGHJ in our patients was similar to reported by the Institute of Hematology of Chinese Academy of Medical Science, albeit that no correlation was found between the IGHV4 usage and the prognosis of the patients. Furthermore, 98% may not be appropriate for distinguishing the IGHV variant status in WM patients.

Objective:
To analyze the clinical characteristics, treatment and prognosis of primary gastric lymphomas (PGL).
Methods:
A retrospective study was conducted in 124 cases of PGL from July 2009 to January 2016 in our hospital, and the clinical records, pathological and immunohistochemical features were analyzed. The relationship between different factors at diagnosis and prognosis were studied.
Results:
124 cases of PGL included 93 diffuse large B cell lymphoma (DLBCL) patients, 25 mucosa associated lymphoid tissue (MALT) lymphoma cases, 1 mantle cell lymphoma, 4 peripheral T-cell lymphoma-not otherwise specified, and 1 extra-nodal NK/T-cell lymphoma-nasal type. Of the 93 primary gastric DLBCL (PG-DLBCL) patients, the germinal center B cell-like (GCB) DLBCL were 45 cases, non-GCB DLBCL were 48 cases. 10 cases (10.8%) of 93 PG-DLBCL were transformed from gastric MALT, and 7 cases (7.5%) have bone marrow involvement. Evidence of Helicobacter pylori infection was detected in 21 cases (51.2%) of 41 DLBCL patients and in 10 cases (43.5%) of 23 MALT patients. Univariate analysis revealed that clinical stages (

Methods:
The clinical data of 118 CLL patients diagnosed from January 2003 to August 2017 were collected. Survival was analyzed according to indicators including sex, age, Binet risk stratification, B symptoms, β2-microglobulin (β2-MG) , immunoglobulin heavy chain variable region gene (IGHV) mutation status, chromosome karyotype and TP53 gene deletion/mutation. The efficacy of first-line CIT of 101 CLL patients was further analyzed.
Results:
Among 118 patients, median progression-free survival (PFS) was 12 (95%
