The microenvironment of lymphoma is an important factor affecting the development of lymphoma, which is involved in regulating the recognition and immune response of lymphoma cells by the immune system. In the era of immunotherapy of lymphoma, the state of microenvironment also affects the effect of monoclonal antibodies, small molecular compounds and other immune targeting drugs on lymphoma cells. Among them, microenvironment-related immune escape is one of the key factors leading to the failure of lymphoma treatment. This article reviews some microenvironment factors such as stromal immune cell subsets, vascular proliferation, hypoxia, immune checkpoint and the recent research progress of immune escape.

Objective To investigate the effect of propofol on the learning and memory function in neonatal rats under hypoxic conditions. Methods Eighty-four 7-day-old SD rats were randomly divided into 6 groups (n = 14 each): propofol + 18% oxygen (propofol-hypoxia, group PH), propofol + air (group PA), propofol +100% oxygen (propofol-oxygen, group PO), 0.9% normal saline (NS) + 18% oxygen (group CH), NS + air (group CA), NS + 100% oxygen (group CO). The rats received injection of intraperitoneal propofol 50 mg/kg or NS 5.0 ml/kg once a day for 7 consecutive days and they were exposed to 18% oxygen, air or 100% oxygen at the end of each injection. SaO2 and respiratory rate (RR) were monitored and recorded after administration. The rats were returned to the cage after recovery of the righting reflex. Six rats in each group were sacrificed 24 h after the 7th injection, and the brain tissues were taken to observe the apoptosis in hippocampal neurons. Morris water maze test was used to test the learning and memory function 2 weeks after administration in the other rats. Results RR was significantly lower and the escape latency at T1.2 longer in group PO than in group CO (P ＜ 0.05). RR and SaO2 were significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crossing the original platform was reduced in group PA compared with group CA, and in group PH compared with group CH (P ＜ 0.05). Compared with group PO, SaO2 was significantly decreased, apoptotic index was increased, the escape latency was prolonged and the frequency of crosing the original platform was reduced in group PA (P ＜ 0.05). Conclusion Propofol induces apoptosis in hippocampal neurons and decreases the learning and memory function in neonatal rats under hypoxic conditions.

Objective To explore the clinical value of wave intensity(WI) curve of the carotid artery in patients with thyroid diseases and its value in evaluating cardiovascular function. Methods All 85 patients with thyroid diseases,including 45 hyperthyroidism and 40 hypothyroidism, were enrolled as case groups,while 270 healthy volunteers were considered as control. All the case groups and control were taken WI test under quiescent condition,and six continuous curves of the carotid artery diameter changes were recorded.Then the parameters of accelerating wave intensity (W1), decelerating wave intensity ( W2), negative area (NA) ,corrected R-W1 and W1-W2,elasticity modulus(Eρ) ,stiffness index(β) ,arterial compliance(AC) and pluse wave velocity(PWV) were calculated. Relationship between those indices and FT3 ,FT4 and TSH were analyzed by Pearson correlative analysis. Results The WI curve appeared differently among different groups,but the vessel elasticity indices did not have statistical significance. Correlation only existed between FT3 and part of the WI parameters. FT3 positively correlated with W1 ( r = 0. 951, P ＜0.01 ), NA( r =0.813, P ＜0.01) and W1-W2' ( r = 0. 887, P ＜0.01 ). And R-W1 ' negatively correlated with FT3( r =-0.878, P ＜0.01 ). Conclusions The WI curve could represent different function status of thyroid,and could be considered as a noninvasive examination for further clinical research,which may help explain the corresponding cardiovascular changes.

Metastasis contributes to the poor prognosis of hepatocellular carcinoma (HCC). However, the mechanism through which a primary HCC cell develops into a metastatic phenotype is not well understood. The purpose of this study was to examine the correlation between metadherin (MTDH)/astrocyte elevated gene-1 (AEG-1) expression in HCC cell lines of different metastatic potentials and such metastatic phenotypes as orientation chemotaxis and adhesion. MTDH/AEG-1 expression was detected by RT-PCR and western blotting in HCC cell lines (HepG2, Huh7, Sk-HEP-1, MHCC-97H). Distribution of MTDH/AEG-1 was observed by immunofluorescence staining and confocal laser scanning microscopy. The abilities of orientation chemotaxis and adhesion and the index of interaction between HCC cell lines and microvascular endothelial cell lines (MVECs, including HUVECs and HPMECs) were measured by chemotaxis assay and adhesion assay, respectively. The results showed that MTDH/AEG-1 protein expression was significantly higher in high metastatic potential cancer cell lines (Sk-HEP-1, MHCC-97H) than in low metastatic potential cell lines (HepG2, Huh7) (P<0.05). The MTDH/AEG-1 protein was localized in the perinuclear region of HCC cells. Furthermore, the abilities of orientation chemotaxis and adhesion of HCC cells to HPMECs were increased as compared with those of HCC cells to HUVECs (P<0.05). The abilities of orientation chemotaxis and adhesion were much stronger in Sk-HEP-1 and MHCC-97H cells with MTDH/AEG-1 highly expressed than in HepG2 and Huh7 cells with MTDH/AEG-1 lowly expressed (P<0.05). These results suggested that the expression of MTDH/AEG-1 gene in HCC cell lines of different metastatic potentials was closely positively related to the abilities of orientation chemotaxis and adhesion of HCC cells. It was deduced that MTDH/AEG-1 might play a pivotal role in the lung-specific metastasis of HCC, which may be mediated through orientation chemotaxis and adhesion abilities of HCC cells. MTDH/AEG-1 may serve as a potential therapeutic target for HCC.

Objective To explore the risk factors of hyperbilirubinemia in late preterm infants. Methods Clinical data of 211 cases of late preterm infants with hyperbilirubinemia and 246 cases of late preterm infants without hyperbilirubinemia were retro-spectively analyzed between 2011 and 2012. The risk factors of hyperbilirubinemia were filtered. Results Twenty-seven cases of late premature infants with hyperbilirubinemia were severe. Hospital stay less than 3 days, birth asphyxia history, small for gestatio-nal age, head hematoma, delivery injury, hypoalbuminemia, polycythemia, infection, hemolytic disease, feeding intolerance, and fe-tal excretion delay were associated with hyperbilirubinemia (P<0.05). Rural origin, pregnancy-induced hypertension syndrome and premature rupture of membrane were also associated with hyperbilirubinemia (P<0.05). Multivariate logistic regression analysis showed the history of birth asphyxia , fetal excretion delay, hypoalbuminemia, pregnancy-induced hypertension syndrome were risk factors of hyperbilirubinemia in late preterm infants (OR=2.35-4.05). Pregnancy-induced hypertension syndrome and hemolytic dis-ease were risk factors of severe hyperbilirubinemia in late preterm infants (OR=5.74, 73.64). Conclusions Neonatal asphyxia, fetal excretion delay, hypoalbuminemia and pregnancy-induced hypertension syndrome are risk factors of hyperbilirubinemia in late pre-term infants. Strengthening the management of pregnancy-induced hypertension syndrome and the treatment of newborn hemolytic disease can reduce the occurrence of severe hyperbilirubinemia in late preterm infants.
