Due to therapeutic regimens for patients with malignant lymphoma (ML) is currently unsatisfactory, it is important to develop new complementary therapies for longer disease-free survival. Dendritic cells (DC) are specialized antigen-presenting cells of immune system and vaccination with tumor antigen-pulsed DC has been applied to treat patients for ML. In this review, we summarize various types of ML-associated antigens and clinical trials on DC-based immunotherapy in ML, and discuss the development of DC immunotherapy for ML patients in future.

Objective To study the psychological nursing on the rehabilitation effect of patients with acute coronary syndrome(ACS)accompanied by depression.Methods 126 ACS patients were divided into the nursing group(64 cases)and the control group(62 cases)randomly.The control group adopted roUtine rehabilitative nursing measurs.While the nursing group received canonical and selective psychological nursing.The Zung Self-rating Depression Scale(SDS)and hamilton depression scale(HAMD)were used to evaluate the their psychological status.The electrocardiogram,clinical symptom and cardiovascular complications were observed and compared.Results The SDS and HAMD scores were different between the nursing group and the control group(P<0.01)5 weeks after rehabilitative nursing but not before it.The ischemic changes of electrocardiogram,incidence frequency of angina pectoris and cardiovascular complications were significantly decreased in the nursing group compared with the control group(P<0.05).Conclusion Psychological nursing could not only alleviate the depression of patients with ACS but also could improve the clinical symptoms of these patients and decrease the incidence frequency of cardiovascular events.

Objective To explore the effect of shRNA silenced aromatic hydrocarbon receptor (AHR) on WNT signaling path-way during the differentiation of P19 cells into cardiac myocytes. Methods The eukaryotic expression vector of mouse AHR gene was designed and constructed. The interference plasmid was transfected into P19 cell and the positive stains to AHR gene silencing were screened by G418. The mRNA expression of important genes GSK3βandβ-catenin were evaluated by real-time fluorescent quantita-tive PCR during the differentiation of P19 cells. Results The constructed AHR-shRNA plasmid significantly inhibited the expression of AHR gene. Along with the differentiation of P19 cell into cardiac myocytes, in the interference group the expression ofβ-catenin gene was lower whereas the expression of GSK3βgene was elevated than those of control group with significant differences (all P<0.01). Conclusions The interference of AHR gene expression can regulate WNT signaling pathway in the development of heart.

Objective:To investigate the clinical effect and mechanisms of ceftriaxone combined with ranitidine on the acute pancreatitis.Methods:92 cases of patients with acute pancreatitis were selected and randomly divided into the control group (n=46) and experimental group (n=46),the control group was treated with ceftriaxone,and the experimental group was treated with ranitidine based on the control group,the serum levels of intedeukin-6 (IL-6),c-reactive protein(CRP),platelet activating factor (PAF),superoxide dismutase (SOD),propylene glycol (MDA),gastric secrete element,stomach,heart rate (HR),mean arterial pressure (MAP),and the relief time of clinical manifestation and the clinical efficacy were observed and compared between the two groups.Results:After treatment,the serum levels ofIL-6,CRP,PAF,MDA,gastric secrete element and HR of experimental group were significantly lower than those of the control group (P<0.05).The serum levels of SOD,stomach motion element and MAP of experimental group were higher than those of the control group (P<0.05).The relief time of clinical manifestation and total efficiency of experimental group were better than those of the control group (P<0.05).Conclusions:Ceftriaxone combined with ranitidine could effectively enhance the clinical efficacy of acute pancreatitis,which might be related to the anti-oxidation and anti-inflammation.

Objective To study the morphological changes of soleus muscle spindle and electrical activity of neurons in Red Nucleus(RN) of the rat after 2 weeks' simulated weightlessness, and to reveal the interaction between proprioceptive inputs of muscle spindles and reciprocal alterations in RN under simulated weightlessness. Methods Twenty female rats were exposed to weightlessness simulated by tail-suspension for 14 days (SW-14d). Body weight(200-220g) matched female rats were control group(Con). The morphological changes in isolated muscle spindle of soleus muscle, the discharges of red nucleus neurons were observed after 14d tail-suspensions by silver staining and extracellular recording respectively. Results Compared with control group ,the nerve ending of muscle spindle in SW-14d was distorted, degenerated and dissolved; the diameters of intrafusal fibers and capsule in equatorial region of soleus muscle spindles were diminished(P<0.05). The spontaneous cell activity and discharge of RN neurons (spikes/s) induced by afferent firing from muscle spindles after injection of succinylcholine were reduced after 2 weeks' simulated weightlessness respectively (18.44±5.96 vs. 10.19±6.88, 32.50±8.08 vs. 16.86±5.97, P<0.01). Conclusion The degeneration of muscle spindle induced by simulated weightlessness may be one of the causes that led to alterations in discharges of RN.

Objective To study the characteristics of its pathologic and neurophysiologic changes of a ani-mal model of cervical spinal cord compression, and to explore the relationship between the severity of spinal cord inju-ry and its functions. Methods Thirty-two rabbits were divided into 4 groups randomly. A catheter was inserted intothe vertebral canal and a balloon was inflated to compress spinal cord in epidural space. According to the diameter ofballoon, the animals were divided into 4 groups (A, B, C, D group), Each group consisted of 8 rabbits. The corti-cal somatosensory evoked potential (CSEP) and motor evoked potential (MEP) were used to assess neurologicalfunction. Motor function behavior was scored before and on 1, 3, 7 and 14 days after surgery. Histological observa-tions were performed, pathological changes were observed by light and electron microscope. Results Spinal cordcompression resulted in a gradual increase of the peak latency and significant decrease of the peak amplitude. The la-tency and amplitude of MEP were changed more dramatically than those of CSEP. The result indicated that MEP wasmore sensitive than CSEP to the compression. Analysis also revealed that the severer the pathologic changes, the lon-ger the latency and the lower the amplitude of the evoked potentials. Conclusion The animal model presented inthis paper was simple and standardized. Evoked potentials as a noninvasive technique have great value in monitoringspinal cord function. The variance of amplitude and the latency in significantly correlate with the degree of compres-sion of the spinal cord.

Objective To investigate the expression of chemokine VCC-1 in hepatocellular carcinoma (HCC).Methods RT-PCR was used to detect the VCC-1 mRNA expressions in 8 HCC cell lines,10 normal liver tissues and 42 HCC tissues.Result In HCC cell lines,the expressions of VCC1 mRNA were high in SUN 398,intermediate in SUN387,SUN449,SUN423,HepG2,PLC5,and low in Hep3B and Huh7.In HCC tissues,the expressions of VCC-1 mRNA could be found in tumor and adjacent tissues.In these 42 tissues,VCC-1 mRNA was highly expressed in 26 specimens of tumor tissues (61%,14.9±7.6 fold) and 16 specimens of adjacent tissues (39%,6.9±5.4 fold).VCC-1 mRNA was up regulated in tumor tissues (P<0.01).The expression levels of VCC-1 mRNA in 2 specimens were related to tumor differentiation and tumor size (P<0.05).In the 10 specimens of normal liver tissues,no expression was detected in 8 specimens and light expression in 2 specimens.The expression was lower compared with cell lines,cancer tissues and adjacent tissues (P<0.01).In 3 cases of recurrence,VCC-1 was highly expressed in cancer tissues (20.1±2.3 fold).In 8 specimenswith tumor thrombosis,5 tissues showed highly expressed VCC-1 (17.3±4.5 fold) while 3 specimens showed low expression.Conclusion VCC-1 plays an important role in HCC,and it may be considered as a potential therapeutic target of HCC.
