Abstract
The bromodomain and extra-terminal (BET) proteins act as "readers" for lysine acetylation and facilitate the recruitment of transcriptional elongation complexes. BET protein is associated with transcriptional elongation of genes such as c-MYC and BCL-2, and is involved in the regulation of cell cycle and apoptosis. Meanwhile, BET inhibitors (BETi) have regulatory effects on immune checkpoints, immune cells, and cytokine expression. The role of BET proteins and BETi in a variety of tumors has been studied. This paper reviews the recent research progress of BET and BETi in hematologic tumors (mainly leukemia, lymphoma and multiple myeloma) from cellular level studies, animal studies, clinical trials, drug combination, etc. BETi has a promising future in hematologic tumors, and future research directions may focus on the combination with other drugs to improve the efficacy.

Abstract
Prostate cancer (PCa) is a prevalent malignant neoplasm affecting the male reproductive system globally. However, the diagnostic and therapeutic approaches fall short of meeting the demands posed by PCa. Poor expression of miRNA-203 (miR-203) within PCa tissues and cells implies its potential utility as a diagnostic indicator for PCa. Exosomes (Exo), membranous vesicles released by various cells, are rich reservoirs of miRNAs. However, the presence of miR-203 presents within Exo derived from PCa cells remains unclarified. In this study, Exo was isolated from urine specimens collected from clinical PCa patients and LNCaP cells to detect miR-203 expression. Meanwhile, the impact of overexpressed miR-203 on M0 macrophages (mø) was analyzed. Subsequently, alterations in the proliferative, migratory, and invasive capacities of LNCaP cells were examined within a co-culture system featuring elevated miR-203 levels in both macrophages and LNCaP cells. Furthermore, the repercussions of miR-203 upregulation or inhibition were explored in a murine PCa tumor model. The results revealed that Exo manifested a circular or elliptical morphology, encapsulating a phospholipid bilayer approximately 100 nm in diameter. Notably, Exo readily infiltrated, with both Exo and miR-203-overexpressing Exo prompting macrophage polarization toward the M1 subtype. In the co-culture system, miR-203 exhibited pronounced suppression of LNCaP cell proliferation, migration, and invasion, while concurrently fostering apoptosis as compared with the LNCaP group (Control). In vivo experiments further disclosed that miR-203 greatly inhibited the growth of PCa tumors in nude mice. Markedly heightened expression of M1 macrophage markers such as IL-1β, IL-6, IL-12, CXCL9, and CXCL10 was observed within the tumor microenvironment following miR-203 intervention, as opposed to the model group. However, the introduction of miR-203 antagomir led to a reversal in tumor growth trends. This investigation indicates the presence of miR-203 within the urine of PCa patients and Exo originating from cells, and that miR-203 exerted antitumor effect by facilitating M1 macrophage polarization. Our study furnishes valuable insights into the potential applicability of miR-203 as a diagnostic biomarker and therapeutic target for PCa.

Abstract
We present an optical method for the manipulation of microparticles using two tilted-focused beams. First, the action on the microparticles is studied with a single tilted-focused beam. The beam is used to drive the directional motion of a dielectric particle. When the optical scattering force is larger than the optical gradient force, the particle is pushed to the tilted side of the optical axis by the optical force. Second, two tilted-focused beams with the same power and complementary tilt angles are used to assemble an optical trap. The trap can be used to realize the optical trapping of the dielectric particles and opto-thermal trapping of the light absorbing particles. The trapping mechanism is the balance of the forces exerted on the particles, including the optical scattering force, optical gradient force, gravity, and thermal gradient force. The trap center is away from the focal spots, which effectively prevents the laser beam from being focused on the trapped object.

Abstract
Objective: To investigate the lifespan of erythrocytes in megaloblastic anemia (MA) patients. Methods: A prospective cohort study analysis. Clinical data from 42 MA patients who were newly diagnosed at the Department of Hematology, Lanzhou University Second Hospital from January 2021 to August 2021 were analyzed, as were control data from 24 healthy volunteers acquired during the same period. The carbon monoxide breath test was used to measure erythrocyte lifespan, and correlations between erythrocyte lifespan and laboratory test indexes before and after treatment were calculated. Statistical analysis included the t-test and Pearson correlation. Results: The mean erythrocyte lifespan in the 42 newly diagnosed MA patients was (49.05±41.60) d, which was significantly shorter than that in the healthy control group [(104.13±42.62) d; t=5.13,P=0.001]. In a vitamin B12-deficient subset of MA patients the mean erythrocyte lifespan was (30.09±15.14) d, and in a folic acid-deficient subgroup it was (72.00±51.44) d, and the difference between these two MA subsets was significant (t=3.73, P=0.001). The mean erythrocyte lifespan after MA treatment was (101.28±33.02) d, which differed significantly from that before MA treatment (t=4.72, P=0.001). In MA patients erythrocyte lifespan was positively correlated with hemoglobin concentration (r=0.373), and negatively correlated with total bilirubin level (r=-0.425), indirect bilirubin level (r=-0.431), and lactate dehydrogenase level (r=-0.504) (all P<0.05). Conclusions: Erythrocyte lifespan was shortened in MA patients, and there was a significant difference between a vitamin B12-deficient group and a folic acid-deficient group. After treatment the erythrocyte lifespan can return to normal. Erythrocyte lifespan is expected to become an informative index for the diagnosis and treatment of MA.

Abstract
OBJECTIVE To compare the differences in pathogenicity and gene expression profiles between adult Schistosoma japonicum isolated from hilly and marshland and lake regions of Anhui Province, so as to provide the scientific evidence for formulating the precise schistosomiasis control strategy in different endemic foci. METHODS C57BL/6 mice were infected with cercariae of S. japonicum isolates from Shitai County (hilly regions) and Susong County (marshland and lake regions) of Anhui Province in 2021, and all mice were sacrificed 44 days post-infection and dissected. The worm burdens, number of S. japonicum eggs deposited in the liver, and the area of egg granulomas in the liver were measured to compare the difference in the pathogenicity between the two isolates. In addition, female and male adult S. japonicum worms were collected and subjected to transcriptome sequencing, and the gene expression profiles were compared between Shitai and Susong isolates of S. japonicum. The differentially expressed genes (DEGs) were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. RESULTS The total worm burdens [(14.50 ± 3.96) worms/mouse vs. (16.10 ± 3.78) worms/mouse; t = 0.877, P = 0.392], number of female and male paired worms [(4.50 ± 0.67) worms/mouse vs. (5.10 ± 1.45) worms/mouse; t = 1.129, P = 0.280], number of unpaired male worms [(5.50 ± 4.01) worms/mouse vs. (5.60 ± 1.69) worms/mouse; t = 0.069, P = 0.946], number of eggs deposited in per gram liver [(12 116.70 ± 6 508.83) eggs vs. (16 696.70 ± 4 571.56) eggs; t = 1.821, P = 0.085], and area of a single egg granuloma in the liver [(74 359.40 ± 11 766.34) µm2 vs. (74 836.90 ± 13 086.12) µm2; t = 0.081, P = 0.936] were comparable between Shitai and Susong isolates of S. japonicum. Transcriptome sequencing identified 584 DEGs between adult female worms and 1 598 DEGs between adult male worms of Shitai and Susong isolates of S. japonicum. GO enrichment analysis showed that the DEGs between female adults were predominantly enriched in biological processes of stimulus response, cytotoxicity, multiple cell biological processes, metabolic processes, cellular processes and signaling pathways, cellular components of cell, organelles and cell membranes and molecular functions of binding and catalytic ability, and KEGG enrichment analysis showed that these DEGs were significantly enriched in pathways of vascular endothelial growth factor signaling, glutathione metabolism, arginine and proline metabolism. In addition, the DEGs between male adults were predominantly enriched in biological processes of signaling transduction, multiple cell biological processes, regulation of biological processes, metabolic processes, development processes and stimulus responses, cellular components of extracellular matrix and cell junction and molecular functions of binding and catalytic ability, and these DEGs were significantly enriched in pathways of Wnt signaling, Ras signaling, natural killer cells-mediated cytotoxicity, extracellular matrix-receptor interactions and arginine biosynthesis. CONCLUSIONS There is no significant difference in the pathogenicity between S. japonicum isolates from hilly and marshland and lake regions of Anhui Province; however, the gene expression profiles vary significantly between S. japonicum isolates.

Abstract
Multiple myeloma (MM) is one of the most common tumors of the hematological system and remains incurable. Recent studies have shown that long noncoding RNA NORAD is a potential oncogene in a variety of tumors. However, the general biological role and clinical value of NORAD in MM remains unknown. In this study, we measured NORAD expression in bone marrow of 60 newly diagnosed MM, 30 post treatment MM and 17 healthy donors by real-time quantitative polymerase chain reaction (qPCR). The NORAD gene was knockdown by lentiviral transfection in MM cell lines, and the effects of NORAD on apoptosis, cell cycle and cell proliferation in MM cells were examined by flow cytometry, CCK8 assay, EDU assay and Western blot, and the differential genes after knockdown of NORAD were screened by mRNA sequencing, followed by in vivo experiments and immunohistochemical assays. We found that knockdown of NORAD promoted MM cell apoptosis, induced cell cycle G1 phase arrest, and inhibited MM cell apoptosis in in vivo and in vitro experiments. Mechanistically, NORAD plays these roles through the BMP6/P-ERK1/2 axis. We discuss a novel mechanism by which NORAD acts pro-tumorigenically in MM via the BMP6/P-ERK1/2 axis.

Abstract
Shiguzhai Hui Ju Jian Bian Dan Fang, was the only medical book for prescription and formula collected and compiled by Wu Mianxue in the period of the Wanli in the Ming Dynasty (1573-1620). It had seven volumes in total with six of them popular at that time. The volumes contained 1,460 folk formula and clinical prescriptions which were divided into 111 categories based on their corresponding symptoms of diseases. The set was issued in the beginning of the 17th century, with only three subsets of the volumes left in China today. The three remained versions were the subset of volumes 4-5 left in the Ming Dynasty in the Medical College of Tianjin, the subset of volumes 1-2 and 6-7, with preface, left in the seventeenth of the Shun Zhi Period in the Qing Dynasty (1660) in the Shanghai University of Chinese Medicine and the subset of volumes 4 and 6-7 from time unknown. Additionally, three unabridged versions were found in the Cabinet Library of the National Archives of Japan. They were the Ming version with preface of the seventeenth of the Shun Zhi Period in the Qing Dynasty and a hand-copied version left in the Edo period. It was found that the preface in the seventeenth of the Shun Zhi Period in the Qing Dynasty in both of these versions in China as well as the version in Japan, were counterfeit. The main texts in these versions were edited according to the Ming version. The hand-copied version in Japan was transcribed by Kasahara Eisan and edited by Tanba Motoken according to the Ming version in the late Edo Period.

Abstract
OBJECTIVE To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. METHODS Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. RESULTS A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ2= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ2 = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). CONCLUSIONS The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Abstract
Human epididymis protein 4(HE4) is a secretory glycoprotein found in human distal epididymis epithelial cells. It is often used in the early diagnosis, efficacy evaluation and monitoring of ovarian cancer, and also has been considered as an effective serum marker for many other types of cancer. However, its function in the process of sperm maturation is not fully unknown. The maturation of sperm in epididymis is characterized by the acquisition of motility and fertilization. As a member of the whey acid protein (WAP) family, several studies proposed the importance of HE4 in the maturity of sperm in epididymis. This article reviews the effect of HE4 on spermatozoa maturation in epididymis, which provides basis for the evaluation of male reproductive ability, early detection, early diagnosis and pathogenesis of male infertility.

Abstract
BACKGROUND Aggressive natural killer cell leukemia (ANKL) is a rare natural killer cell neoplasm characterized by systemic infiltration of Epstein–Barr virus and rapidly progressive clinical course. ANKL can be accompanied with hemophagocytic lymphohistiocytosis (HLH). Here, we report a case of ANKL with rare skin lesions as an earlier manifestation, accompanied with HLH, and review the literature in terms of etiology, clinical manifestation, diagnosis and treatment.
CASE SUMMARY A 30-year-old woman from Northwest China presented with the clinical characteristics of jaundice, fever, erythema, splenomegaly, progressive hemocytopenia, liver failure, quantities of abnormal cells in bone marrow, and associated HLH. The immunophenotypes of abnormal cells were positive for CD2, cCD3, CD7, CD56, CD38 and negative for sCD3, CD8 and CD117. The diagnosis of ANKL complicated with HLH was confirmed. Following the initial diagnosis and supplementary treatment, the patient received chemotherapy with VDLP regimen (vincristine, daunorubicin, L-asparaginase and prednisone). However, the patient had severe adverse reactions and complication such as severe hematochezia, neutropenia, and multiple organ dysfunction syndrome, and died a few days later.
CONCLUSION This is the first reported case of ANKL with rare skin lesions as an earlier manifestation and associated with HLH.

Abstract
Acute leukemia (AL) is a highly heterogeneous hematologic malignancy, and although great progress has been made in the treatment of AL with allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and new targeted drugs, problems such as infection and GVHD in AL treatment are still serious. How to reduce the incidence of AL, improve its prognosis and reduce the side effects of treatment is a crucial issue. The gut microbiota plays an important role in regulating disease progression, pathogen colonization, and immune responses. This article reviews recent advances in the gut microbiota and AL pathogenesis, infection, treatment and its role in allo-HSCT.

Abstract
BACKGROUND Bendamustine was approved in China on May 26th, 2019 by the National Medical Product Administration for the treatment of indolent B-cell non-Hodgkin lymphoma (NHL). The current study was the registration trial and the first reported evaluation of the efficacy, safety, and pharmacokinetics of bendamustine in Chinese adult patients with indolent B-cell NHL following relapse after chemotherapy and rituximab treatment. METHODS This was a prospective, multicenter, open-label, single-arm, phase 3 study (NCT01596621; C18083/3076) with a 2-year follow-up period. Eligible patients received bendamustine hydrochloride 120 mg/m2 infused intravenously on days 1 and 2 of each 21-day treatment cycle for at least six planned cycles (and up to eight cycles). The primary endpoint was the overall response rate (ORR); and secondary endpoints were duration of response (DoR), progression-free survival (PFS), safety, and pharmacokinetics. Patients were classified according to their best overall response after initiation of therapy. Proportions of patients in each response category (complete response [CR], partial response [PR], stable disease, or progressive disease) were summarized along with a two-sided binomial exact 95% confidence intervals (CIs) for the ORR. RESULTS A total of 102 patients were enrolled from 20 centers between August 6th, 2012, and June 18th, 2015. At the time of the primary analysis, the ORR was 73% (95% CI: 63%-81%) per Independent Review Committee (IRC) including 19% CR and 54% PR. With the follow-up period, the median DoR was 16.2 months by IRC and 13.4 months by investigator assessment; the median PFS was 18.6 months and 15.3 months, respectively. The most common non-hematologic adverse events (AEs) were gastrointestinal toxicity, pyrexia, and rash. Grade 3/4 neutropenia was reported in 76% of patients. Serious AEs were reported in 29 patients and five patients died during the study. Pharmacokinetic analysis indicated that the characteristics of bendamustine and its metabolites M3 and M4 were generally consistent with those reported for other ethnicities. CONCLUSION Bendamustine is an active and effective therapy in Chinese patients with relapsed, indolent B-cell NHL, with a comparable risk/benefit relationship to that reported in North American patients.

Abstract
A sensitivity- and resolution-improving method for a low-frequency micro-vibration accelerometer is presented in this paper. A sensitivity model of the measurement system is derived and established. The key parameters that limit the sensitivity and the resolution of the accelerometer were identified through the sensitivity coefficient analysis method. The structural parameters and the signal process method were then optimized. Experimental results show that the sensitivity of the accelerometer has improved from 1.10 V/(m/s2) to 19.21 V/(m/s2), and the resolution has improved from 1.47 mm/s2 to 0.21 mm/s2. The lowest working frequency range has expanded from 1 Hz to 0.7 Hz. The presented method is effective and cheap and can be applied to other sensors.

Abstract
Intracranial hemorrhage (ICH) is a devastating complication of immune thrombocytopenia (ITP). However, information on ICH in ITP patients under the age of 60 years is limited, and no predictive tools are available in clinical practice. A total of 93 adult patients with ITP who developed ICH before 60 years of age were retrospectively identified from 2005 to 2019 by 27 centers in China. For each case, 2 controls matched by the time of ITP diagnosis and the duration of ITP were provided by the same center. Multivariate analysis identified head trauma (OR = 3.216, 95%CI 1.296-7.979, P =.012), a platelet count ≤ 15,000/μL at the time of ITP diagnosis (OR = 1.679, 95%CI 1.044-2.698, P =.032) and severe/life-threatening bleeding (severe bleeding vs. mild bleeding, OR = 1.910, 95%CI 1.088-3.353, P =.024; life-threatening bleeding vs. mild bleeding, OR = 2.620, 95%CI 1.360-5.051, P =.004) as independent risk factors for ICH. Intraparenchymal hemorrhage (OR = 5.191, 95%CI 1.717-15.692, P =.004) and a history of severe bleeding (OR = 4.322, 95%CI 1.532-12.198, P =.006) were associated with the 30-day outcome of ICH. These findings may facilitate ICH risk stratification and outcome prediction in patients with ITP.

Abstract
In this Rapid Communication, the Rayleigh-Taylor instability (RTI) along the density interfaces of gravity current fronts is analyzed. Both the location and the spanwise wave number of the most unstable mode determined by the local dispersion relation agree with those of the strongest perturbation obtained from numerical simulations, suggesting that the original formation mechanism of lobes and clefts at the current front is RTI. Furthermore, the predictions of the semi-infinite RTI model, i.e., the original dominating spanwise wave number of the Boussinesq current substantially depends on the Prandtl number and has a 1/3 scaling law with the Grashof number, are confirmed by the three-dimensional numerical simulations.

Abstract
Objective: To understand the status of occupational health surveillance for workers on offshore platforms. Methods: The research period was from 2014 to 2016. From 2014 to 2016, a cross-sectional survey method was adopted to select 429 people for offshore oil production, drilling and operation platforms and their first-line workers to conduct workplace occupational hygiene. Investigation, occupational hazard factor testing, occupational health check of workers, collation and statistical analysis of surveys and test data, and comparison of occupational health surveillance among workers of different types of offshore platforms. Results: From 2014 to 2016, the results of chemical harmful factors detection of occupational diseases in the offshore platform were in line with the national occupational health exposure limit requirements. The noise of some platform posts exceeded the standard, such as: oil platform oil, oil and oil and gas processing workers, diesel engines for drilling and working platforms. Worker noise exceeds national occupational health limits p[L(ex, 8 h)>85 dB(A)].There was a statistically significant difference in the occupational health of workers on the same platform with the age and length of service (P<0.05). Conclusion: Workers on different platforms at sea may be subject to different levels of occupational health damage, and the occupational hazards brought by noise to platform workers are particularly prominent.

Abstract
Objective: To observe the efficacy and safety related measures by blocking mother-to-child transmission of hepatitis B virus with high viral load and HBeAg positivity during pregnancy in Guizhou province. Methods: Outpatient and inpatient cases of the Department of Infectious Diseases and Obstetrics of Guizhou Medical University Affiliated Hospitals from May 2016 to July 2017 were retrospectively divided into intervention group, non-intervention group and non- hepatitis B pregnant women group; with 75 cases in each group. HBsAg and HBeAg were positive in the intervention group. Pregnant women with HBV DNA ≥10(6) IU/ml were treated with anti-HBV therapy for 24 to 28 weeks of gestation until delivery. According to oral drugs, they were divided into tenofovir (TDF) group or telbivudine (LDT) group, non-intervention group (HBsAg and HBeAg positive), HBV DNA positive pregnant women, pregnant women with no anti-HBV drugs, non-hepatitis B pregnant women (normal pregnant women without HBV infection). Infants and young children born to the three groups of women were immunized with the national viral hepatitis B action plan. The gestational weeks and Apgar scores at birth, delivery mode, feeding mode, sex and 7-months-old age were observed and counted. Serum hepatitis B markers (HBVM) and HBV DNA were quantitatively detected. HBVM was detected by time-resolved fluorescence immunoassay (TRFIA), and HBV DNA was detected by real-time PCR (FQ-PCR). The changes of liver parameters, HBsAg, HBeAg, HBV DNA, adverse drug reactions and treatment response of pregnant intervention group before medication (12-24 weeks of gestation), 4 weeks of medication (28-32 weeks of gestation), 36-40 weeks of gestation (36-40 weeks of gestation) were statistically calculated. A t-test was used to compare the data between the measurements. Data measurements within the groups were analyzed using rank -sum test. Results: In the intervention group, therapeutic medications showed no differences in demographic and clinical characteristics between TDF group and LDT group, including liver parameters, HBsAg, HBeAg and log10HBV DNA level. Compared with pre-treatment (TDF group: 4.84 ± 2.01; LDT group: 5.08 ± 1.99), TDF and LDT were significantly lower at the end of pregnancy (TDF group: 3.06 ± 0.66; LDT group: 3.51 ± 1.20). P < 0.05); and the treatment response rate was 100%. There were no serious adverse events in the intervention group. Infants and young children (7-months-old) in the intervention group had negative HBsAg, HBeAg and HBV DNA. The mother-to-child transmission rate of HBV was zero, with blocking rate of 100%. In addition, both infants and young children had different degrees of hepatitis B protective antibodies (anti-HBs, M: 144.33), and their antibody titers were higher than that of non-intervention group (anti-HBs, M: 65.91) and non-hepatitis B pregnant women (anti-HBs, M: 58.43). The difference was statistically significant (P < 0.05), and there was no significant correlation between the use of antiviral and the way of delivery and feeding. Outcomes of mother-to-child transmission of HBV infection in infants and young children (7-months-old) delivered by three groups of pregnant women in the non-intervention groups had 20.0% (15/75)/ 17.3% (13/75) HBsAg/HBeAg positivity rate, and 17.3% (13/75) HBV DNA positivity rate. Overall, mother-to-child transmission rate of HBV infection was 20% (15/75). Furthermore, the relationship between mother's HBV DNA load and infant HBV infection in the non-intervention group showed mother's HBV DNA ≥10(6) IU/ml. Conclusion: In the non-intervention group, mother-to-child transmission of HBV occurred, and infected mothers HBV DNA was ≥106 IU/ml before delivery. This suggests that HBeAg positive and high load HBV DNA replication were independent risk factors for mother-to-child transmission of hepatitis B. Therefore, prenatal drug intervention and postpartum standard immune blockade are necessary for high-risk pregnant women with hepatitis B to achieve zero mother-to-child transmission of hepatitis B in real- clinical practice.

Abstract
An artificial diet formulated for continuous rearing of the predator Arma chinensis was inferior to natural prey when evaluated using life history parameters. A transcriptome analysis identified differentially expressed genes in diet-fed and prey-fed A. chinensis that were suggestive of molecular mechanisms underlying the nutritive impact of the artificial diet. Changes in the diet formulation were made based on the transcriptome analysis and tested using life history parameters. The quantity of pig liver, chicken egg, tuna fish, biotin, nicotinamide, vitamin B6, thiamine, riboflavin, vitamin C, L-glutamine, and sucrose was reduced, and wheat germ oil, calcium pantothenate and folic acid were increased. Ecuadorian shrimp was added as a partial substitute for tuna fish. Several parameters improved over six generations, including increased egg viability, and decreased egg and adult cannibalism. Additionally, several parameters declined, including longer developmental times for 2nd-5th instars, and decreased nymphal weights. The improvements in life history parameters support the use of transcriptome analyses to help direct formulation improvements. However, the decline in some parameters suggests that additional information, e.g., proteomic data, may be useful as well to maximize diet formulations.

Abstract
Low-frequency vibration is a harmful factor that affects the accuracy of micro/nano-measuring machines. Low-frequency vibration cannot be completely eliminated by passive control methods, such as the use of air-floating platforms. Therefore, low-frequency vibrations must be measured before being actively suppressed. In this study, the design of a low-cost high-sensitivity optical accelerometer is proposed. This optical accelerometer mainly comprises three components: a seismic mass, a leaf spring, and a sensing component based on a four-quadrant photodetector (QPD). When a vibration is detected, the seismic mass moves up and down due to the effect of inertia, and the leaf spring exhibits a corresponding elastic deformation, which is amplified by using an optical lever and measured by the QPD. Then, the acceleration can be calculated. The resonant frequencies and elastic coefficients of various seismic structures are simulated to attain the optimal detection of low-frequency, low-amplitude vibration. The accelerometer is calibrated using a homemade vibration calibration system, and the calibration experimental results demonstrate that the sensitivity of the optical accelerometer is 1.74 V (m·s−2)−1, the measurement range of the accelerometer is 0.003–7.29 m·s−2, and the operating frequencies range of 0.4–12 Hz. The standard deviation from ten measurements is under 7.9 × 10−4 m·s−2. The efficacy of the optical accelerometer in measuring low-frequency, low-amplitude dynamic responses is verified.

Abstract
To observe the effect of Xiaoqinglong decoction combined with noninvasive ventilation on procalcitonin (PCT), blood gas analysis and respiratory functions in acute exacerbation of chronic obstructive pulmonary disease in the elderly (AECOPD), and investigate its correlation and clinical significance. Eighty-four elderly AECOPD patients with respiratory failure in our hospital from January 2015 to October 2017, were randomly divided into control group and observation group, 42 cases in each group. The control group received western medicine combined with noninvasive ventilator therapy, and the patients in observation group additionally received Xiaoqinglong decoction on the basis of the treatment in control group. Both groups were treated for 2 weeks. The clinical effects of two groups were observed and their PCT, blood gas analysis outcomes [arterial oxygen partial pressure (PaO₂), arterial partial pressure of carbon dioxide (PaCO₂), respiratory function, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC], TCM syndrome score and other indexes and adverse reactions were compared before and after treatment. The total efficiency was 95.24% (40/42) in observation group, higher than 76.19% (32/42) in control group, with statistically significant difference (P<0.05). There were no statistically significant differences in PCT, PaO₂, PaCO₂, FVC, FEV1/FVC, FEV1, and TCM syndrome scores between two groups before treatment. But after treatment, PCT and PaCO₂ levels in the observation group were lower and PaO₂, FVC, FEV1/FVC, FEV1 levels was higher than those in the control group (P<0.05); TCM syndrome scores were lower than those in the control group (P<0.05); both groups had no obvious adverse reactions. The results showed that Xiaoqinglong decoction combined with noninvasive ventilator could significantly reduce the procalcitonin level, effectively improve the respiratory function and blood gas analysis indexes, and significantly reduce the clinical symptoms in AECOPD patients, so it is worthy of promotion.

Abstract
The present study aimed to explore the regulatory effects of endoplasmic reticulum stress (ERS) on the phosphoinositide 3‑kinase (PI3K)/AKT serine/threonine kinase 1 (AKT)/mammalian target of rapamycin (mTOR) signaling pathway, and its subsequent effects on autophagy and apoptosis of human leukemia cells. Human leukemia cells were cultured and treated with various concentrations of tunicamycin for 0, 24, 48, 72 and 90 h. Subsequently, human leukemia cells were assigned into the ER activation group, which was treated with 100 ng/ml tunicamycin, the ER activation + TO901317 (PI3K inhibitor) group, and the control group. An MTT assay was conducted to detect cell proliferation. In addition, a monodansylcadaverine (MDC) assay was used to detect the formation of autophagosomes and Annexin V‑fluorescein isothiocyanate/propidium iodide double staining was used to examine cell apoptosis. Western blotting was performed to detect the expression levels of 78‑kDa glucose‑regulated protein (GRP78), phosphorylated (p)‑protein kinase R‑like endoplasmic reticulum kinase (PERK), p‑α subunit of eukaryotic initiation factor 2 (eIF2α), microtubule‑associated protein 1A/1B‑light chain 3 (LC3), caspase‑3, CCAAT‑enhancer‑binding protein homologous protein (CHOP), PI3K, AKT and mTOR. Treatment with 100 ng/ml tunicamycin for 72 h was considered the optimal condition for further experiments. Compared with in cells prior to treatment, human leukemia cells treated with tunicamycin exhibited increased expression of p‑PERK, p‑eIF2α and GRP78 after 72 h (P<0.05). In addition, the expression levels of mTOR, AKT and PI3K were decreased in the ER activation group compared with in the control and ER activation + TO901317 groups (P<0.05). Compared with in the control group, cell proliferation was inhibited and MDC fluorescence intensity was increased in the ER activation group (P<0.05). Furthermore, compared with in the control and ER activation + TO901317 groups, western blotting indicated that the expression levels of LC3‑II were increased in the ER activation group (P<0.05). The apoptotic rate was also higher in the ER activation group compared with in the control group (P<0.05), and caspase‑3 and CHOP expression was elevated in the ER activation group (P<0.05). These findings indicated that ERS may induce autophagy and apoptosis of human leukemia cells via inhibiting the PI3K/AKT/mTOR signaling pathway.

Abstract
This study aimed to investigate the effectiveness of perioperative nursing intervention on patients undergoing laparoscopic gastric stromal tumor resection. Sixty patients with gastric stromal tumor were selected from our hospital and evenly divided into group A and group B. Patients in both groups underwent laparoscopic resection. Patients in group A were given conventional nursing intervention before and after surgery, while those in group B were given comprehensive nursing intervention. Various indicators were compared between the two groups. The amount of bleeding of group B was less than that of group A, and the first anal exsufflation of group B was also earlier than that of group A; the differences had statistical significance (p less than 0.05). Patients in group B felt less pain than patients in group A; except for 72 h after surgery, difference of pain degree between group A and B had statistical significance in other periods (p less than 0.05); the number of cases with complications and categories of complications of group B were less than those of group A, and the difference had statistical significance (p less than 0.05). The efficacy satisfaction of group B was also higher than that of group A, and the difference was statistically significant (p less than 0.05). Perioperative nursing intervention is beneficial and positive and has bright development prospects.

Abstract
Objective: To investigate the effect of platycodin D on the radiosensitivity of human hepatoma cell lines HepG2 and SMMC-7721 and related mechanisms of action. Methods: MTT assay was used to analyze the effect of different concentrations of platycodin D with different treatment times on cell viability. The cells were pretreated with 5 μg/ml platycodin D for 24 hours followed by X-ray irradiation at different radiation doses. Colony-forming assay was used to measure the radiosensitizing effect of platycodin D on cells. The quasi-threshold dose (Dq), mean lethal dose (Do), extrapolation number (N), sensitizer enhancement ratio (SER), and survival fraction (SF) at different radiation doses were calculated, and the multi-target single-hit model was used to fit the cell survival curve according to the formula SF = l-(l-e(-D/D0))N. Flow cytometry was used to investigate the distribution of cell cycle, and Western blotting was used to measure the changes in the protein expression of phosphorylated phosphatidylinositol 3'-kinase (pPI3K), phosphorylated protein kinase (pAkt), nuclear factor-κB (NF-κB), and phosphorylated nuclear factor inhibiting protein (pIκBα). A one-way analysis of variance, the t-test, or the least significant difference test was used for statistical analysis based on the type of data. Results: Platycodin D reduced the viability of HepG2 and SMMC-7721 cells in a dose-dependent manner; the IC50 value for HepG2 cells was 24.2 ± 0.61 μg/ml at 24 hours and 7.68 ± 0.46 μg/ml at 48 hours, and that for SMMC-7721 cells was 23.8 ± 0.57 μg/ml at 24 hours and 8.63 ± 0.86 μg/mL at 48 hours. After the combined treatment with platycodin D and irradiation, there were significant reductions in Dq (P = 0.002), Do (P = 0.002), and N value (P = 0.003), the survival curve markedly shifted to the left, and SER was 1.347 ± 0.04 in HepG2 cells and 1.418 ± 0.05 in SMMC-7721 cells. In addition, platycodin D significantly inhibited the increase in the proportion of cells in G2/M phase, the increases in the protein expression of pPI3k (P = 0.002), pAkt (P = 0.003), and NF-κB (P = 0.002), and the reduction in the protein expression of pIκBα (P = 0.003). Conclusion: Platycodin D can increase the radiosensitivity of HepG2 or SMMC-7721 cells, possibly by enhancing the growth inhibition effect of irradiation and inhibiting the activation of the PI3k/Akt and NF-κB pathways.

Abstract
OBJECTIVE Our study aimed to investigate the effects of the long non-coding RNA MALAT-1 (lncRNA MALAT-1) regulated autophagy-related signaling pathway on chemotherapy resistance in diffuse large B-cell lymphoma (DLBCL). METHODS Human normal B lymphocytes (IM-9I) and DLBCL cell lines (Farage, Pfeiffer, Raji, Daud, Ly1, Ly3, Ly8 and Ly10) were chosen for our experiment. qRT-PCR was applied to detect the expression of lncRNA MALAT-1 in each DLBCL cell line. Farage and Daud cells were induced to be drug-resistant using 0.05μg/ml Adriamycin. LncRNA MALAT-1 interfering stable transfected cell lines were constructed and cells were transfected with lentivirus. The cells were divided into the blank, siNC, and siRNA-MALAT-1 groups. CCK-8 assay, flow cytometry, and Transwell assay were performed to detect cell survival rate, cycle, apoptosis, and invasion, respectively. The autophagosome formation in each group was observed under a transmission electron microscope. Western blotting was used to detect the expressions of the autophagy-related proteins and genes. The in vivo drug sensitivity of the tumor was observed using a subcutaneous tumor xenograft model in nude mice. RESULTS The expression of lncRNA MALAT-1 in each DLBCL cell line was higher than in the IM-9 cells, with the Farage cells ranking highest (all P<0.05). When compared with the blank and the siNC groups, the siRNA-MALAT-1 group showed a decreased cell survival rate, an increased percentage of cells in G0/G1 phase, a decreased proportion of cells in S and G2/M phases, and a reduced number of migratory cell at each time point (all P<0.05). When compared with the blank and the siNC groups, the formation of autophagosomes, increased LC3-II/LC3-I expression, decreased p62 expression, and increased expression of the autophagy gene ATG5 were observed in the siRNA-MALAT-1 group at each time point (all P<0.05). Also, the siRNA-MALAT-1 group had a decreased tumor volume and weight in the subcutaneous tumor xenograft model in nude mice, and increased LC3-II/LC3-I expression but decreased p62 expression in tumor tissues when compared with the blank group and the siNC group (all P<0.05). CONCLUSION Our study provides evidence that inhibiting lncRNA MALAT-1 can improve the chemotherapy sensitivity of DLBCL by enhancing autophagy-related proteins.

Abstract
BACKGROUND Curdione is one of the most highly concentrated component of the active constituents in E-zhu, which has been reported to possess a variety of activities. However, the pharmacologic neuroprotective activity of curdione has not been evaluated. The present study aimed to investigate the protective effect of curdione on focal cerebral ischemia reperfusion-induced injury in rats and further exploring the underlying mechanisms. MATERIALS AND METHODS Adult male Sprague Dawley rats were subjected to middle cerebral artery occlusion (MCAO) surgery for 2 h, followed by reperfusion stage. All animals received treatment once a day for 7 days before surgery and 14 days from 4 h after the reperfusion started. The neurological deficit test and Morris water maze test were performed at 1, 4, 7 and 14 days after MCAO. The infarct size of animals was determined by the 2,3,5-triphenyltetrazolium chloride staining, and pathological brain damage was estimated by hematoxylin-eosin staining. The malonaldehyde (MDA) levels and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-PX) were detected by enzyme-linked immunosorbent assay. Expression of apoptotic proteins was measured by Western blot. RESULTS Our results showed that curdione could significantly reduce the infarct size and neurological deficits, promote cognitive function recovery and recover neuronal morphologic damages in MCAO rats. It also blocked the increase of MDA content and elevated the activities of SOD, CAT and GSH-PX. Moreover, curdione attenuated the expression of Cyt-C, c-caspase-3 and c-caspase-9 increased the Bcl-2/Bax ratio and hence decreased the cellular apoptosis. CONCLUSION Curdione possessed potential neuroprotective effect on rats in the MCAO model. The anti-oxidative and anti-apoptotic properties may be involved in the underlying mechanisms.

Abstract
Laryngeal cancer is the major malignant tumor affecting the upper respiratory tract. Previous studies have reported on the association between XRCC1 genetic polymorphisms and risk of laryngeal cancer, but with conflicting results. In this study, we attempted to assess the association between XRCC1 Arg194Trp, Arg280His and Arg399Gln polymorphisms and risk of laryngeal cancer in a Chinese population. A total of 126 laryngeal cancer patients and 254 control subjects were recruited to this study from the Second Medical College of Jinan University between December 2013 and May 2015. The XRCC1 Arg194Trp, Arg280His, and Arg399Gln polymorphic sites were genotyped by polymerase chain reaction-restriction fragment length polymorphism. Our results revealed a significant association between the AA genotype of XRCC1 Arg280His [odds ratio (OR) = 2.51, 95% confidence interval (CI) = 1.29-4.87, P = 0.01] and an increased risk of laryngeal cancer susceptibility compared to the GG genotype. Moreover, the A allele showed a higher risk of laryngeal cancer susceptibility compared to the G allele (OR = 1.63, 95%CI = 1.19-2.50, P = 0.002). In conclusion, the results of our study suggest that the AA genotype and A allele of the XRCC1 Arg280His polymorphism are associated with an increased laryngeal cancer risk in a Chinese population.

Abstract
In the experiments reported here, we used the female ladybird Coccinella septempunctata L. as a model to identify diapause-associated proteins using proteomics technology. Our results indicated that protein expression patterns of diapausing and nondiapausing individuals were highly differentiated. A total of 58 spots showed significant differences in abundance (Ratio > 2 and P < 0.05) according to two-dimensional electrophoresis and GE Image Scanner III analysis. Sixteen protein spots were further investigated using mass spectrometry. Eight proteins were characterized, including chaperones and proteins involved in glucose metabolism, lipid metabolism, and the tricarboxylic acid cycle. Among these proteins, five proteins were upregulated in diapausing female adults, including a chaperone (Symbionin symL), malate dehydrogenase (putative), two proteins linked to lipid metabolism (unknown and conserved hypothetical protein) and phosphoglyceromutase (partial). By contrast, isocitrate dehydrogenase (RH49423p), fumarylacetoacetate hydrolase (AGAP001942-PA), and a putative medium chain acyl-CoA dehydrogenase were downregulated. These results contribute to the understanding of diapause mechanisms of the ladybird C. septempunctata and may suggest methods for improving the application of this natural enemy insect.

Abstract
High stocking density (STD) could affect duck welfare and production. The objective of our study was to investigate whether dietary tryptophan (TRP) supplementation could alleviate the detrimental effects of high STD on ducks. White Pekin ducks at 4 to 6 wk of age were raised at 11 birds/m(2) and fed diets containing 0.18, 0.48, 0.78, or 1.08% TRP for 21 d. Growth performance, concentrations of TRP and metabolites in the blood and hypothalamus, antioxidative activities in serum and tissue, meat quality, serum uric acid, and urea nitrogen were measured. Weight gain and feed efficiency were significantly improved by TRP supplementation at ≥ 0.48 and ≥ 0.78% (P < 0.05 and P < 0.001, respectively). Serum TRP, hypothalamic TRP, 5-hydroxytryptamine (5-HT), 5-hydroxyindoleacitic acid (5-HIAA), and 5-HIAA/5-HT were also increased significantly (P < 0.01). These increases plateaued at 0.48% TRP, and no further improvement was obtained by adding more TRP to the diet. Dietary TRP supplementation significantly increased levels of total antioxidant capacity, glutathione peroxidase (GSH-Px), and catalase (CAT) in serum; GSH-Px in liver; and GSH-Px and CAT in breast muscle (P < 0.05). Malondialdehyde levels in breast muscle decreased (P < 0.001). Drip loss of breast muscle and pH decline at 45 min postmortem were reduced by TRP supplementation (P < 0.01 and P < 0.05, respectively). Meat color was similar among different treatments (P > 0.05). Breast muscle shear force was increased significantly when dietary TRP level increased to 1.08% (P < 0.01). For ducks raised at 11 birds/m², dietary TRP supplementation could alleviate stress and improve growth performance, antioxidative activity, and meat quality.

Abstract
The impact of a zoophytogenous, insect-free artificial diet and a secondary prey, pupae of Chinese oak silk moth Antheraea pernyi (Guérin-Méneville) (Lepidoptera: Saturniidae), on the developmental rate, life history parameters, and fertility was examined for F6, F9, and F12 consecutive generations for domesticated Arma chinensis (Fallou) (Heteroptera: Pentatomidae). This study showed that when fed an insect-free artificial diet during both the nymphal and adult stages, developmental times were prolonged, and fecundity, egg viability, net reproductive rates (R0), and intrinsic rates of increase (rm) declined. As a result, the cost to rear A. chinensis on the artificial diet approached 1.7 times the cost of rearing A. chinensis on pupae of A. pernyi. Future diet improvements should attempt to reduce developmental time, increase fecundity, and egg viability and use less costly nutrient sources.

Abstract
In an attempt to establish the advantages of fluorescence in situ hybridization (FISH) studies over conventional cytogenetic (CC) analysis, a total of 2302 de novo MDS patients from 31 Chinese institutions were prospectively selected in the present study for both CC and standardized FISH analysis for +8, -7/7q-, -5/5q-, 20q- and-Y chromosomal abnormalities. CC analysis was successful in 94.0% of the patients; of these patients, 35.9% of the cases were abnormal. FISH analysis was successful in all 2302 patients and detected at least one type of common cytogenetic abnormality in 42.7% of the cases. The incidences of +8, -7/7q-, -5/5q-, 20q- and-Y chromosomal abnormalities by FISH were 4.1% to 8.7% higher than those by CC. FISH identified abnormalities in 23.6% of the patients exhibiting normal CC results and revealed that 20.7% of the patients with adequate normal metaphases (≥20) had abnormal clones. FISH identified cytogenetic abnormalities in 50.4% of the patients with failed CC analysis. In summary, our multicenter studies emphasised and confirmed the importance of applying standardized FISH testing based on an appropriate panel of probes to detect common cytogenetic abnormalities in Chinese de novo MDS patients, particularly those with normal or failed CC results.

Abstract
Spontaneous remission (SR) of leukemia is a rare event in clinic, which possibly correlated with severe infection and sepsis, but its exact mechanism has not been confirmed. Plasmacytoid dendritic cells (pDC) and myeloid dendritic cells (mDC) play a key role in innate and adaptive immunity respectively. A patient with severe infection of staphylococcus aureus acquired completely spontaneous remission (SR), moreover a increased number of pDC were observed, suggesting that bacteria-activated pDC may play an important role in SR. This study was purposed to explore if the bacteria can stimulate pDC successfully and get a functional pDC. Both pDC and mDC were isolated from freshly collected, leukocyte-rich buffy coats from healthy blood donor and leukemic patient with SR by using MACS and FACS. The pDC were cultured in RPMI 1640 medium and were stimulated with different kinds of bacteria and the expression of CD40, CD86 and HLA-DR on the cell surface was analyzed by flow cytometry. The cytokine (IFN-α, IL-12, IFN-γ, IL-2, IL-4, IL-10) production was measured by using ELISA kits. The results showed that the stimulation with staphylococcus aureus and pseudomonas aeruginosa resulted in the maturation of pDC, which secrete a large number of IFN-α and promote the differentiation of naive CD4⁺ T cells to Th1 cells. The activated pDC expressed high level of CD40 and CD86 and showed higher T cell stimulatory capacities. It is concluded that staphylococcus aureus and pseudomonas aeruginosa can activate pDC, the activated pDC secrete high quantity of IFN-α. This result suggests that bacteria stimulated pDC may play a key role in SR of leukemia following severe infections.

Abstract
The purpose of study was to investigate the in vitro proliferation ability of PHA-induced CIK cells and traditionally prepared CIK cells, the effector cell level and its influence on killing activity to K562 cells, and to analyze the difference between them. The peripheral blood mononuclear cells(PBMNC) of healthy persons were isolated and divided into A and B group. The CIK cells in A group were obtained by using traditional culture method, the CIK cells in B group were prepared by PHA induction. During the cultivation, the cell survival rate and cell absolute value in the cell culture system were counted every 3 days. On day 15 of culture, the cell immunophenotype of 2 groups were detected by flow cytometry, and the ratios of CD3(+)CD56(+), CD3(+)CD8(+) and CD3(+)CD4(+) cells in total cell amount of culture system were accounted. Meantime, the killing activity to K562 cells in different effector-target ratios was detected by using CCK-8 kit between the 2 groups. The results showed that the method of preparing CIK by PHA induction promoted the cell proliferation more than that of the traditional method (P < 0.05), moreover, both the survival rate of cells in 2 groups was more than 90%. The CD3(+)CD8(+), CD3(+)CD56(+) cell ratio in 2 groups obviously increased. As compared with traditional method, the CD3(+)CD8(+) cell level in B group was enhanced (P < 0.05); but there were no statistical differences in increase of CD3(+)CD56(+) cell level and decrease of CD3(+)CD4(+) cell level between 2 groups. while the effector-target ratio is 5:1, 10:1, 20:1 and 40:1, the killing activity of PHA-induced CIK cells to K562 cells was more stronger than traditionally-prepared CIK cells (P < 0.05), moreover, along with increase of effector-target ratio, the difference of killing activity to K562 cells in 2 groups significantly increased. It is concluded that compared with traditional method for preparing CIK cells, the new way by PHA induction can increase the proliferation of CIK cells obviously, enhance the ratio of CD3(+)CD8(+) cells and strengthen the killing activity to the K562 cells. This new way provides a new source of CIK cells and reliable evidence for cyto-immune therapy of leukemia and other tumors.

Abstract
This study was purposed to investigate the effect of high-dose dexamethasone (DXM) on function and Toll like receptor 9 (TLR-9) expression of plasmacytoid dendritic cells (pDC) in peripheral blood of patients with immune thrombocytopenic purpura (ITP). 15 newly diagnosed patients with ITP received high dose DXM at single daily doses of 40 mg for 4 consecutive days. The peripheral blood plasmacytoid dendritic cells from 13 remission patients and 15 normal controls were separated by immunomagnetic beads and then induced by CpG-OND2216. 24 h later, the levels of IFN-α, IL-6 and TNF-α in the supernatant were detected by enzyme linked immunosorbent assay (ELISA). The expression of TLR9 mRNA of pDC was detected by real-time quantitative PCR. The results indicated that the levels of IFN-α, IL-6 and TNF-α produced by pDC in ITP patients were significantly higher than those in normal controls (P < 0.05). After high dose DXM treatment, the levels of IFN-α, IL-6 and TNF-α decreased without significant difference compared with normal controls (P > 0.05). The expression of TLR9 mRNA in pDC of untreated patients was significantly higher than that in control group (P < 0.05), and significantly reduced after treatment without difference from that in control group (P > 0.05). It is concluded that pDC may play an important role in ITP by their TLR9 and secreted cytokines; dexamethasone may down regulate the expression of TLR9, inhibit pDC function, and thus play a therapeutic role.

Abstract
The objective of this study was to explore the effect of astragalus polysaccharide (APS) on sensitivity of leukemic cell line HL-60 to NK cell cytotoxicity and its mechanism. The cytotoxicities of NK cells against HL-60 cells were analyzed by LDH releasing assay at different effect-to-target cell ratios (E:T) before and after treated with APS. The gene expression of MHC class I chain-related (MICA) in HL-60 cells before and after APS treatment was assayed with RT-PCR. Protein expression of MICA in HL-60 cells was assayed by flow cytometry before and after treated by APS. The results showed that after treated with APS 15 mg/ml for 48 h, the cytotoxicities of NK cells against HL-60 cells enhanced at different effect-to-target (P < 0.05), and the gene and protein expressions in MICA of HL-60 cells were up-regulated (P < 0.05). It is concluded that the APS can obviously up-regulate the expression of MICA in HL-60 cells, thus enhance sensitivity of HL-60 cells to cytotoxicity of NK cells.

Abstract
This study was aimed to investigate the immunological effect of modified dendritic cells (DC) which inducing cytotoxic T cells (CTL) against lymphoma cells. The DC were isolated from the lymph node and peripheral blood of patients with diffuse large B cell lymphoma (DLBCL). DC were transfected with recombinant adenovirus vector carrying human p53 gene (rAd-p53-DC). The expression of p53 gene was detected by flow cytometry. Western-blot was used to detect the expression of P53. ELISA was used to detect IL-12 level in supernatant. The mixed lymphocyte reaction (MLR) was used to detect the proliferative ability of auto-lymphocyte stimulated by DC. The lactate dehydrogenase (LDH) release test was used to determine the cytotoxicity of CTL. The results indicates that the expressions of DC surface molecule (except for CD1a) such as CD83, CD80, CD86 and HLA-DR were significantly higher in experiment group than that in control group and blank control group. The secretion of IL-12 in supernatant was higher in experiment group than that in control group. The autologous T lymphocyte proliferation and cytotoxic activity against the same kind of DLBL-cells increased in experiment group as compared with control group and blank control group (P < 0.05). The ability to stimulate T lymphocyte proliferation increased with the rising of the ratio of DC and T lymphocyte. However, there was statistically significant difference between rAd-p53-DC derived from Lymph node and peripheral blood (P < 0.05). It is concluded that rAd-p53-transfected DC can induce CTL response in vitro against lymphoma cells.

Abstract
BACKGROUND AND OBJECTIVE Leukemia is a malignant tumor highly dependent on nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB), which is relevant for the occurrence, metastasis, proliferation, apoptosis, and drug resistance of tumor cells. Research has confirmed that the NF-kappaB family is one of the target genes in the Notch signaling pathway. This study investigated the effects of Celastrol on the apoptosis of U937 cells and the expression levels of Notch1 and NF-kappaB in these cells. METHODS U937 cells were treated with various concentrations Celastrol (0.5-16.0) micromol/L for 12-60 h. MTT assay was performed to examine the effect of Celastrol on growth inhibition of U937 cells. Cell apoptosis was detected through both Annexin-V FITC/PI double-labeled cytometry and transmission electron microscopy (TEM). Cell cycle regulation was studied by propidium iodide. Western blot analysis and reverse transcription-polymerase chain reaction (RT-PCR) technologies were applied to assess the expression level of Notch1 in U937 cells. Subcellular distributions of NF-kappaB/p65 were detected through confocal microscopy. RESULTS Celastrol presented striking growth inhibition and apoptosis induction potency on U937 cells in vitro in a time- and dose-dependent manner. The IC50 value of Celastrol for 24 h was (6.21 +/- 0.242) micromol/L. Moreover, Celastrol induced apoptosis in U937 cells in a cell-cycle dependent manner, which means that Celastrol could arrest U937 cells in the G0/G1 phase. Through TEM, apoptotic bodies containing nuclear fragments were found in Celastrol-treated U937 cells. Overexpression of Notch1 was found in U937 cells, while Celastrol could downregulate it at both the protein and mRNA level in a dose-dependent manner, and expression of NF-kappaB decreased in nuclei and increased in the cytoplasm (P < 0.05). CONCLUSIONS Celastrol inhibited cell proliferation and induced apoptosis in U937 cells in a concentration-dependent manner. The possible mechanism might be involved in the regulation of a survival signaling pathway, such as Notch or NF-kappaB.

Abstract
BACKGROUND Toxoplasma gondii can infect all warm-blooded animals. Modified agglutination test (MAT) and ELISA are widely used for the detection of T. gondii antibodies. However, there is little information on their acceptability for detecting antibodies in companion animals. METHODS This study compared ELISA and MAT for their ability to detect T. gondii infection in naturally infected dogs and cats. Blood samples were collected from dogs and cats in different areas of Beijing, China and analyzed by ELISA and MAT. The χ(2) test and κ analysis were used to evaluate their efficiency and agreement. RESULTS For dogs, the seroprevalence of T. gondii antibodies detected by ELISA was 34.7%, which was significantly higher than that detected by MAT (P<0.05). There was no significant difference between ELISA and MAT for detecting T. gondii antibodies in cats. Good agreements between MAT and ELISA were seen in both dogs and cats; however, inconsistent results were demonstrated by κ analysis and in MAT titer assay. CONCLUSION Serum-based ELISA may be more satisfactory for screening test of T. gondii infection in dogs, whereas both methods could be acceptable in cats.

Abstract
Human immunodeficiency viruses 1 and 2 (HIV-1, 2) present a public health problem for which there is neither an effective antiviral therapy nor a preventive vaccine. In this study, the immune responses of mice to prime-boost vaccination with the recombinant DNA (rDNA) and recombinant Fowlpox virus (rFPV) both expressing HIV-2 Gag-gp105 chimeric protein, were compared to those elicited by each vector alone. Mice primed with the rDNA and boosted with the rFPV showed HIV-2-specific antibody levels, splenic CD4+ and CD8+ T-lymphocyte numbers, and Gag-gp105-specific cytotoxic T-lymphocytes (CTL) activity increased by 20-30% as compared with those elicited by these vaccines alone. These findings suggested that the prime-boost strategy combining rDNA and rFPV elicited significant Gag-gp105 - specific cellular and humoral immune responses, thus supporting this novel approach to the immunization against HIV infections.

Abstract
OBJECTIVE To explore the effect of astragalus polysaccharide (APS) on the function and maturation of chronic myelogenous leukemia (CML) peripheral blood mononuclear cells (PBMC)-derived plasmacytoid dendritic cells (pDCs). METHODS CML-derived pDCs were sorted by flow cytometry, and then incubated with APS (at 0, 50, 100 and 200 mg/L). After 24 hours, the concentrations of IFN-α, IL-6, TNF-α were detected with ELISA. Five days later, the cultured cells were collected and analyzed for immotype, morphology and ultramicrostructure. RESULTS The level of IFN-α, IL-6, TNF-α was significantly higher in samples from CML remission group than that in untreated pDCs, and newly diagnosed pDC (P < 0.05) or untreated group. APS could promote more pDCs differentiating to dendritic cells (DCs) in CML remission group than in untreated-pDCs in a dose-dependant manner (P < 0.05). CONCLUSION APS can enhance the immune function of pDCs, promote differentiation and maturation of pDCs from CML patients.

Abstract
OBJECTIVE To investigate the proportion of Th17 cells in the peripheral blood of the patients with acute myeloid leukemia (AML) and evaluate the potential association of Th17 cells with AML. METHODS The cytokines IL-17 and TGF-β1 in the peripheral blood of AML patients before therapy (group 1), AML patients in complete remission (AML-CR, group 2) and healthy donors (group 3) were measured by enzyme-linked immunosorbent assay (ELISA). The proportion of Th17 cells of each group was evaluated by flow cytometry. The level of IL-17 mRNA of each group was examined by reverse transcription-PCR (RT-PCR). RESULTS The percentage of Th17 cells and the level of IL-17, IL-17 mRNA in group 1 \[(10.502 ± 1.071) ng/L, (0.935 ± 0.140)% and 0.262 ± 0.510\] and group 2 \[(11.345 ± 0.987) ng/L, (1.091 ± 0.159)% and 0.307 ± 0.031\] was significantly lower than that in group 3 \[(16.852 ± 1.198) ng/L, (2.586 ± 0.235)% and 0.501 ± 0.060\]. The percentage of Th17 cells and the level of IL-17, IL-17 mRNA in group 1 was lower than that in the group 2. But the level of TGF-β1 in the group 1 (29.963 ± 1.588) ng/L and the group 2 (25.163 ± 1.848) ng/L was significantly higher than that in group 3 (13.366 ± 1.565) ng/L. However, the level of TGF-β1 in the group 3 was higher than that of the group 2. CONCLUSION Th17 cells might be negatively correlated with the AML development. The overexpression of TGF-β1 in AML patients might suppress the differentiation of Th17 cells.

Abstract
BACKGROUND AND OBJECTIVE Bone marrow mesenchymal stem cells (MSCs) are of particular interest due their potential clinical use in tissue engineering. MSCs could secret soluble factor(s) upon stimulation. This study was to evaluate the influence of human bone marrow MSCs on proliferation of chronic myeloid leukemia cells, and assess the secretion of cytokines in the supernatant induced by MSCs. METHODS Bone marrow MSCs extracted from healthy donors were cultured in DMEM-LG. The surface markers on the third passage MSCs were detected by flow cytometry. MSCs were co-cultured with chronic myeloid leukemia mononuclear cells (CML-MNCs) at various ratios. Cell proliferation was measured by flow cytometry. The interferon (IFN)-alpha level in the supernatant was analyzed by ELISA assay. RESULTS The primary and passaged MSCs mostly appeared fibroblast-like and showed strong capacity of growth and reproduction. The membrane marker CD44 was positive and CD45 was negative on the surface of MSCs. Co-culture of MSCs with CML-MNC significantly inhibited the proliferation of CML-MNC. The IFN-alpha level in the supernatant of cell culture was significantly higher in the co-culture groups than in the CML-MNC control group (p < 0.001). Secretion of IFN-alpha was elevated with the increase of the MSC concentration and co-culture duration. CONCLUSION Co-culture of MSCs with CML could secrete a substantial amount of IFN-alpha, thus to inhibit the proliferation of CML cells.

Abstract
This study was purposed to investigate the possibility of differentiating the acute promyelocytic leukemia (APL) cells into dendritic cells (DCs) induced by all-trans retinoic acid (ATRA) combined with classic cytokines so as to provide a new approach for development of APL-DC vaccine. The bone marrow mononuclear cells from a new diagnosed patient with APL and HL-60 cells were separately cultured in complete culture medium. The cells were treated by ATRA, GM-CSF, IL-4 and TNFalpha in experimental groups and no ATRA was added in control and blank control groups. The cell morphology was observed by light microscopy, the phenotypes of DCs were detected by flow cytometry, the level of IL-12 was measured by using ELISA, the mixed lymphocyte reaction (MLR) and effect of cytotoxic T-lymphocyte (CTL) were assayed by MTT method. The results indicated that in experiment groups, the cells had dendritic appearance and cytogenetic characteristics of APL; expression of CD1a, CD83, CD80, CD86, HLA-DR and CD1d as well as level of IL-12 obviously increased; the MLR and CTL effects were significant, but increase of CD1a expression in HL60-DCs did not show statistical difference from control and blank control groups. It is concluded that ATRA can successfully induce APL cells to differentiate into functionally mature DSs which obviously mediate MLR and CTL effects. The APL-DCs derived by ATRA can notably express CD1d that may activate CD1d-restricted NKT cells and promote proliferation of NRT cells. The exact mechanism of which should be further studied.

Abstract
Programmed death-1 ligand-1(PD-L1) is a recently identified member of the B7 family molecules and is shown to mediate the inhibition of immune responses. This study was purposed to enhance the weak immunological function of dendritic cells (DCs) derived from the patients with chronic myelocytic leukemia (CML) by blockade of the expression of PD-L1. Bone marrow mononuclear cells (BMMNCs) of CML patients were induced into DCs in the presence of cytokine cocktail of rhGM-CSF, rhIL-4 and TNF-alpha. The phenotypes of DCs were detected by flow cytometry, mixed lymphocyte reaction was analyzed by MTT assay and IFN-gamma, IL-2 and IL-10 in the cell culture supernatant were detected by ELISA. The results showed that the expression of PD-L1 on CML-DCs was upregulated with the maturation of CML-DCs. PD-L1-blockaded DCs could enhance T lymphocyte proliferation, increase the secretion of IL-2 and IFN-gamma, and inhibit the production of IL-10. Taken together, PD-L1-blockaded DCs originated from CML cells had more potent immunostimulatory capability. It is concluded that PD-L1 blockaded can enhance the function of CML-DCs. This approach presents new possibilities for achieving anti-tumor immunity by DC-based vaccination.

Abstract
OBJECTIVE A lot of studies have suggested that a certain amount of T cells may be involved among cytokine-induced killer (CIK) cells. The aim of the present study was to prove whether an antigen-specific killing effect on tumor cells is involved during the CIKs-induced killing process. METHODS Bone marrow mononuclear cells (BMMNCs) derived from healthy subjects were separately cultured to generate dendritic cells (DC) and CIKs. A human mammary cancer cell line MCF-7/ADR, expressing P-gp antigen, was frozen-thawed and the lysate including P-gp antigen was obtained. The DC pulsed with or without tumor antigen lysate was co-cultured with CIK (pulsed-DC + CIK and DC + CIK), and CIK cultured alone was used as control. The cell phenotype of DC and CIK was analyzed by flow cytometry. The secretion of IL-12 and IFN-gamma was assayed by ELSA. The antitumor effect of the three CIK groups targeted at MCF-7/ADR cells expressing P-gp antigen and MCF-7 cells was detected by MTT. RESULTS Pulsed-DC + CIK group and DC + CIK group showed a higher expression level of DC mature phenotypes than those before co-culture with CIK, with a significant difference (P = 0.003, P = 0.001, respectively). The phenotypes (CD3, CD8, CD56) of CIK in pulsed-DC + CIK group and DC + CIK group was higher than those in CIK group (P = 0.003, P = 0.011, respectively). Among the three CIK groups, pulsed-DC + CIK group had the highest phenotypes on CD3+ CD56 (pulsed-DC + CIK vs. DC + CIK, P = 0.001; pulsed-DC + CIK vs. CIK, P < 0.001) and CD3 CD8 (P = 0.002, P = 0.002, respectively). Among the three groups, the pulsed-DC + CIK group showed the lowest CD45RA phenotype (pulsed-DC + CIK vs. DC + CIK, P < 0.001; pulsed-DC + CIK vs. CIK, P = 0.004). Among the three groups the secretion of IL-12 and IFN-gamma had the highest level in pulsed-DC + CIK group, with a value of 254 +/- 14.5 pg/ml and 3100 +/- 286 pg/ml, respectively. The antitumor killing effect on MCF-7/ADR cells had a significant difference between any two groups (pulsed-DC + CIK VS. DC + CIK, P = 0.039; pulsed-DC + CIK VS. CIK, P = 0.002; DC + CIK vs. CIK, P = 0.049). The highest was in pulsed-DC + CIK group and the lowest was in CIK group. The CIK group showed a significantly lower antitumor effect on MCF-7 cells than the other two groups (pulsed-DC + CIK vs. CIK, P = 0.007; DC + CIK vs. CIK, P = 0.048), but no significant difference between the pulsed-DC + CIK and DC + CIK groups. CONCLUSION In the present study, DC and CIK cells have been successfully obtained and cultured from bone marrow mononuclear cells. After their co-culture, not only both their specific phenotypes were increased, but also the associated cytokines were secreted. An improved antitumor killing effect and some possible specific immunocytotoxicity were observed. Our findings provided a basis for experimental and clinical research on bio-immunotherapy targeted at multi-drug resistant tumor cells.
