ABSTRACT
Follicular lymphoma is an indolent malignant tumor originating from lymph nodes and lymphoid tissues, which may affect the patients' quality of survival due to the recurrence and progression. In recent years, with the deepening understand of the molecular biology and signaling pathways, many new targeted drugs for follicular lymphoma have been discovered, such as monoclonal antibodies, checkpoint inhibitors, epigenetic regulation related targeted therapies and signaling pathway inhibitors. In this review, the new progress of immunotherapy for follicular lymphoma is summarized briefly.

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a very rare cutaneous malignant lymphoma derived from cytotoxic T cells that mainly involves subcutaneous adipose tissue rather than epidermis and dermis. It usually occurs in young and middle-aged population, and the etiology is currently unclear. Clinically, SPTCL is characterized by subcutaneous plaques, nodules, and skin ulcers with swell and ache, mainly presenting in limbs and trunk. SPTCL has been restricted to cases that express α/β phenotype, whereas cases with γ/δ phenotype are categorized to cutaneous γ/δ

<p><b>OBJECTIVE</b>This study aims to prepare docetaxel (DOC)-loaded multifunctional nanoparticles containing indocyanine green (ICG) and perfluorohexane (PFH) as targeted drug delivery system, which is supplemented with stromal cellderived factor-1 (SDF-1), and characterize their properties.</p><p><b>METHODS</b>Multifunctional nanoparticles were prepared by using the double emulsion method. SDF-1 was covalently conjugated to the surface of the nanoparticles through thioether bonding. Their particle size, distribution, and surface potential were determined with the Malvern measuring instrument. The conjugation of SDF-1 was evaluated by confocal laser scanning microscope. Encapsulation efficiency (ELC), drug loading capacity (DLC), and release regularity of the nanoparticles were determined by high-performance liquid chromatography (HPLC). In vitro photothermal property was recorded by a thermal imager. The in vitro imaging capacity was observed by a photoacoustic instrument and an ultrasonic diagnostic apparatus. Targeting capability was assessed by flow cytometry. The cell activity on SCC-15 cells was checked by CCK-8 method.</p><p><b>RESULTS</b>The targeted multifunctional nanoparticles showed regularly sphericity. The diameter was (502.88±17.92) nm. The zeta potential was (-11.5±3.15) mV. ELC was 54.12%±1.74%. DLC was 1.08 mg·mL-1. In vitro drug release was initially fast and subsequently slow. The photothermal characteristics were related to the concentration; the higher the concentration, the higher the temperature. Nanoparticles could detect significant photoacoustic and ultrasound signals. The in vitro targeting rate was 89.99%. No significant differences of cell viability in the SINPs groups were observed at each concentration (P>0.05). The inhibition effect of DOC-SINPs was stronger than that of SINPs whether or not in the presence of laser irradiation among the groups of 150 and 200 μg·mL-1 (P< 0.05).</p><p><b>CONCLUSIONS</b>Multifunctional nanoparticles for diagnosis and treatment were successfully prepared and displayed dualmode ultrasound/photoacoustic imaging and antitumor effects of chemotherapy and photothermal therapy.</p>
ABSTRACT
<p><b>OBJECTIVE</b>To explore the prognostic value of regulatory T cells (Tregs) and M2 macrophages in diffuse large B-cell lymphoma (DLBCL) tissues.</p><p><b>METHODS</b>The expression of CD163 and Foxp3 was detected by immunohistochemistry in 92 cases of DLBCL, and it was statistically analyzed whether their expressions correlate with clinical data and prognosis in patients with DLBCL.</p><p><b>RESULTS</b>The density of M2 macrophage and regulatory T cells in DLBCL tumor tissues was significantly higher than that in the adjacent tissues (P = 0.02, P = 0.04). The expression of M2 macrophages was significantly positively correlated with regulatory T cells expression (r = 2.012, P < 0.05). High density of M2 or Tregs had a relationship with extranodal involvement (P < 0.05). Cox regression analysis showed that the expressions of CD163 and Foxp3 were independent prognostic factors of DLBCL (P < 0.05).</p><p><b>CONCLUSIONS</b>Combined detection of the expression of CD163 and Foxp3 proteins and then evaluation of the amount of M2 macrophages and Tregs can be used to more closely predict the prognosis for DLBCL patients.</p>

<p><b>BACKGROUND</b>The computed tomography (CT) findings of invasive pulmonary aspergillosis (IPA) are unclear in non-hematological patients. The present study was a retrospective evaluation of CT images in non-hematological patients with IPA.</p><p><b>METHODS</b>All adult patients who met the 2008 European Organization for Research and Treatment of Cancer/Mycoses Study Group (EORTC/MSG) criteria for proven or probable IPA were included during a 5-year study at our institutions. Initial CT findings in our cohort were retrospectively reviewed by two independent thoracic radiologists blinded to patient demographics and clinical outcomes. The presence, pattern, and distribution of abnormalities were recorded.</p><p><b>RESULTS</b>Twenty-three non-hematological patients with pathologically confirmed IPA were included in our study. Areas of ground-glass opacities were present in 14 patients (61%), which were bilateral in 10 patients and unilateral in four. This pattern mainly involved the middle and upper lung zones. Air-space consolidation was identified in 12 patients (52%), and the areas were distributed along the bronchus or subpleura in most cases. Other findings, including five small nodules (22%), three macronodules (13%), and one halo sign (4%), were less common.</p><p><b>CONCLUSIONS</b>CT findings of IPA in non-hematological patients frequently manifested as acute bronchopneumonia, and ground-glass opacities and air-space consolidations were the most common CT findings of IPA in these patients.</p>

<p><b>OBJECTIVE</b>The aim of this study was to assess the expression of cell division cycle 7 (Cdc7) kinase and minichromosome maintenance protein 2 (MCM2) in diffuse large B cell lymphoma (DLBCL) and explore their relationship with prognosis of DLBCL patients.</p><p><b>METHODS</b>Clinical data of 60 DLBCL patients treated in our hospital from 2008.1 to 2010.1 were collected. The expression levels of Cdc7 and MCM2 in peripheral blood and bone marrow were determined by real-time PCR. A statistical analysis was carried out to evaluate their association with prognosis in DLBCL patients.</p><p><b>RESULTS</b>The 2-year survival rate of patients with high expression of peripheral blood Cdc7 was 38.3% and those with low expression 65.4% (P = 0.001). The 2-year survival rate of patients with high expression of bone marrow Cdc7 was 37.2% and those with low expression was 75.5% (P = 0.032). The 2-year survival rate of patients with high expression of MCM2 in peripheral blood was 44.0% and those with low expression was 68.2% (P = 0.025). The 2-year survival rate of patients with high expression of MCM2 in bone marrow was 39.0% and those with low expression was 63.4% (P = 0.007). A poor disease specific survival was observed in DLBCL patients with high level expression of Cdc7 and MCM2.</p><p><b>CONCLUSIONS</b>Cdc7 and MCM2 expression can be used to assess tumor proliferation and may be useful as an additional marker in combination with conventional markers in prediction of the outcome of DLBCL patients. Moreover, the Cdc7 and MCM2 signal pathway might be useful as a new approach in the treatment of refractory DLBCL lymphoma patients.</p>

<p><b>OBJECTIVE</b>To investigate the correlations between the resistant degree of Tca8113 agaist carboplatin and the expression of excision repair cross-complementation 1 (ERCC-1).</p><p><b>METHODS</b>Tca8113 cells were exposed in the carboplatin solutions of gradually increasing concentration. Cancer cells were divided into six experimental groups and a control group. In the course of culture, the half inhibitory concentration (IC(50)) of each groups were detected by methyl thiazolyl tetrazolium (MTT). The expressions of ERCC-1 at mRNA and protein level were detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting.</p><p><b>RESULTS</b>With the increase of drug resistance, the expression of ERCC-1 increased gradually at mRNA level (control group: 0.84 ± 0.06, group 1: 0.96 ± 0.06, group 2: 1.07 ± 0.11, group 3: 1.13 ± 0.09, group 4: 1.19 ± 0.08, group 5: 1.29 ± 0.07, group 6: 1.47 ± 0.08), values between neighboring or interval groups have significant differences (P < 0.05); the expression of ERCC-1 increased gradually at protein level (control group: 0.69 ± 0.05, group 1: 0.86 ± 0.04, group 2: 1.01 ± 0.04, group 3: 1.24 ± 0.09, group 4: 1.44 ± 0.14, group 5: 1.56 ± 0.19, group 6: 1.88 ± 0.22), values between neighboring or interval groups have significant differences (P < 0.05). The gradually increasing RT-PCR gray values were related to the gradually increasing IC(50) in all groups (r = 0.91, P < 0.01), and the gradually increasing western blotting gray values were also related to the gradually increasing IC(50) in all groups (r = 0.88, P < 0.01).</p><p><b>CONCLUSIONS</b>The high expression of ERCC-1 may become an indicator of Tca8113 resisting carboplatin. This might provide a potential target to reverse tongue squamous cell cancer (Tca8113) that has resistance to carboplatin.</p>

<p><b>OBJECTIVE</b>To explore the morbidity, clinical characteristics, diagnosis, metastasis, treatment and prognosis of primary breast lymphoma (PBL).</p><p><b>METHODS</b>From January 1960 to August 2007, 49 cases with PBL were treated among 22811 cases of breast malignancy and 7337 cases of malignant lymphoma. The clinical data of these 49 patients, included gender, age, pathologic type, breast X ray and B ultrasound examination results, involved lymph nodes and organs, treatment, survival time, were retrospectively analyzed.</p><p><b>RESULTS</b>From 1960 to 2007, the incidence rate of PBL in Tianjin Municipality was 59/10 millions; in details, the incidence rate of PBL for every 10 years was 2/10 millions, 3/10 millions, 0, 13/10 millions and 32/10 millions, respectively. According to circle graph of age, PBL occurred frequently in female aged 30 to 59 years. Most of this group of PBL was non-Hodgkin lymphoma (48 cases). No typical characteristics was found with the examination of breast X ray, B ultrasound and frozen section pathology. Bone marrow (9 cases), lung (7 cases), meninges (4 cases) and ovary (4 cases) were frequently involved organs. The overall 5-year survival rate was 6.1% for the group. The prognosis in patients with radical mastectomy combined chemotherapy was much better than that in patient received super to local mastectomy plus chemotherapy or simple tumor resection plus chemotherapy (5-year survival rates were 21.4%, 0, 0, respectively).</p><p><b>CONCLUSIONS</b>PBL is a kind of rare lymphoma with incidence increasing sharply in the past few decades. The clinical manifestation is atypical. Diagnosis of PBL should adopt histological examination. Radical mastectomy combined chemotherapy could bring better prognosis, but the prognosis is still poor.</p>

Recurrent spontaneous abortion (RSA),which affects 1% to 5% of women of reproductive age,is difficult to treat in the clinical setting. In the investigations of immunopathogenesis,diagnosis and treatment of RSA since the late 1980s,it was found that RSA was associated with abnormal maternal local or systemic immune response,the pathogenesis of autoimmune RSA was mainly associated with antiphosphlipid antibody (APA),while that of alloimmune RSA was due to the disturbance of maternofetal immunological tolerance. Systemic etiological screening process and diagnosis systems of RSA with immune type were developed,and anticardiolipin (ACL)+? 2-GP1 combining multiple assay for effective diagnosis of RSA with immune type was initially established. According to dynamic monitoring clinical parameters before and during gestation,low-dose,short-course and individual immunosuppressive therapy and lymphocyte immunotherapy for RSA with immune type were initiated. The outcomes of the offsprings of patients with RSA were followed up,and the safety and validity of the therapies were confirmed. The research achievement leads to great progress in the diagnosis and treatment of RSA in China.
