This study aimed to explore clinical features of multiple myeloma in patients over 80 years old. Methods: We retrospectively analyzed 11 cases of multiple myeloma over 80 years old, which were diagnosed from 2000 to 2013 in our hospital. Results:The mean age was 83.5 years. All patients had more than two complicated diseases, and the performance status was poor in the majority of the patients. Ten cases received individualized treatments. The results showed that three patients had progressed, one patient achieved complete remission, three patients achieved partial remission, and four patients achieved minor remission. Median survival time was 28 months. The causes of death included six progressed myelomas, three pneumonias, and two acute myocardial infarctions. Conclusion: Patients aged 80 years old with myeloma are often at a late stage. Treatment should be individualized based on patient status. Survival time was evidently prolonged in very elderly patients with MM after individualized treatments, particularly in patients in stagesⅠandⅡ.

Objective:We clarify the relationship between dysfunction of gastric motility and the plasma motilin,in order to study the pathogenesis,diagnosis and therapy of the hepatocirrhosis with dyspepsia.Methods:The liquid gastric emptying (GE),electrogastrograpgy(EGG) and plasma motilin were examined in 51 patients with hepatocirrhosis.Results:The dysfunction of gastric motility is associated with the liver function,gastric rhythm and upper gastrointestinal symptom.The plasma motilin concentration increased significantly in patients with hepatocirrhosis as compared with that of controls (P<0.01).The sorbefacient prokinetic drug (prepulsid) can improve the function of gastric power,but the lever of motilin no change.Conclusion:The patients with hepatocirrhosis have the dysfunction of gastric motility,and gastric emptying delayed,and there is a relation between GE and the liver function.We evaluate that this disorder is associated with the low sensitivity about stomach to the plasma molitin in this case.We can judge the degree of the liver damage,gastric emptying delayed.gastric rhythm by testing the gastric motilin.Drug can deal it.

The CD19-targeted chimeric antigen receptor (CAR) T-cell treatment has achieved clinical success in treating B-cell lineage hematopoietic malignancies. This accomplishment involved the precise and efficient elimination of tumor cells by tumor-associated an-tigen-redirected immune cells. As a result, the reinitiation of several CAR T-cell (CART) based clinical trials in solid tumors was promot-ed. However, developing a feasible and efficient CAR T based therapeutic modality for solid tumors is urgently needed given the differ-ential properties between liquid and solid tumors. In this review, we discuss the advances in the management of cytotherapeutic mo-dality for solid tumors. The aspects considered include toxicity management, target selection, and primer or conditioning treatment.

Aim To evaluate the effect of 15-hydroxy eicosatetraenoic acid(15-HETE) on the tension of isolated internal carotid artery(ICA) rings in normoxic or hypoxic rats in order to find out the pathophysiological effect of 15-HETE in ischemic/hypoxic brain tissues.Methods Sixteen healthy Wistar rats were randomly divided into two groups(n=8): group A with normal oxygen supply(FiO_2 21%) and group B with hypoxia(FiO_2 10%).9 days later,the rats were killed and the ICA rings were prepared.15-HETE in different concentration were added accordingly,and the after washing up,blockers of different kinds of K~+ channels such as 2 mmol?L~(-1) 4-AP,10~(-2) mol?L~(-1) TEA and 10~(-6) mol?L~(-1) GLYB were added to the KH solution separately,followed by the administration of 10~(-6) mol?L~(-1) 15-HETE.The isometric tension was recorded using a four-channel force-displacement transducer.Results The ICA tension was significantly increased both in groups A and B by 15-HETE in concentration-dependent manner(P0.05,n=8).Furthermore,10~(-2) mol?L~(-1) TEA,10~(-6) mol?L~(-1) GLYB had little effects on the tension of rings.Application of 10~(-6) mol?L~(1) 15-HETE after administration of TEA or GLYB induced nearly the same increase in ICA tone as it happened in the group administered with 10~(-6)mol?L~(-1) 15-HETE alone.Conclusion 15-HETE can induce brain vasoconstriction especially under the hypoxic condition.Voltage-dependent potassium channels play an important role in 15-HETE induced constriction.

Objective: The present study investigates the effects of Tanreqing injection, a compound Chinese herbal medicine, on the proliferation of leukemia cells in vitro and discusses the potential mechanisms. Methods: Tanreqing injection was diluted to a series of concentrations (1:2, 1:4, 1:8, 1:16, 1:32, 1:64, 1:128, 1:256 and 1:512) by volume and then independently applied to treat chronic myeloid leukemia K562 cells and T cell acute lymphocytic leukemia Molt4 cells at the proliferative stage. Cell growth was observed at different time intervals under a microscope. Cell proliferation was determined by cell counting kit-8 assay and the survival curve was delineated. The inhibitory rate and the half inhibitory concentration (IC50) were calculated. Molt4 cells were stained with propidium iodide (PI) and PI/Annexin V and then the cell cycle and apoptosis were analyzed by using flow cytometry. In addition, a real-time quantitative polymerase chain reaction was subjected to detect the expressions of apoptosis-related genes (bcl-2 and caspase-3) after Tanreqing treatment. Results: Tanreqing injection had inhibitory effects on the proliferation of K562 cells and Molt4 cells. The most toxic concentrations were observed between 1:2 and 1:16 where cells were almost necrotic. The inhibitory effect manifested in a concentration- and time-dependent manner. The IC50 of K562 and Molt4 was 1:333 and 1:142, respectively. After 1:32 Tanreqing injection treatment for 72 h, the number of Molt4 cells in the S phase significantly decreased (P<0.05), and the apoptosis rate markedly increased (P<0.05). In addition, increased caspase-3 expression and decreased bcl-2 expression were also observed (P<0.05). Conclusion: Tanreqing injection can both inhibit the proliferation and promote the apoptosis of leukemia cells in vitro, whereby the potential mechanism seems to be mediated in part by decreasing S phase ratio, down-regulating bcl-2 expression and up-regulating caspase-3 expression.

Objective To assess the clinical value of serum soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) for diagnosis of early-onset neonatal sepsis (EONS).Methods A total of 90 neonatal cases with risk factors or symptoms of bacterial infections were enrolled in the study.All infants were admitted to Huai' an Maternity and Child Healthcare Hospital within 24 h after birth during January and June 2014.The enrolled neonates were divided into sepsis group (n =33),general infection group (n =23) and non-infected group (n =34);and the sepsis group was further divided into culture-confirmed group (n =6) and clinical-diagnosed group (n =27).Twenty healthy neonates were also enrolled as the healthy control group.Blood samples were obtained from neonatal patients on d1,d3 and d7 after birth,and for healthy controls,the blood samples were only obtained at the first day.Serum levels of sTREM-1 and interleukin (IL)-6 were measured by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA).The receiver operating characteristic (ROC) curve was applied to evaluate the values of sTREM-1 and IL-6 in diagnosis of EONS.Results Compared with that in general infection group,non-infected group and healthy control group,the serum level of sTREM-1 was significantly higher in sepsis group (all P ＜ 0.05);serum levels of sTREM-1 in general infection group and non-infected group were also higher than that in healthy control group (all P ＜ 0.05);but no difference was observed between general infection group and non-infected group,between culture-confirmed group and clinical-diagnosed group (P ＞ 0.05).Serum level of sTREM-1 showed upward trend during d1-3 after the birth,and downward trend during d3-7.The areas under the ROC curve (AUC) were 0.810 and 0.811 (all P ＜ 0.05) for sTREM-1 levels on d1 and d3 in diagnosis of EONS,and the optimal cut-off values were 234.44 ng/L and 269.79 ng/L,respectively.If sTREM-1 and IL-6 on d1 were combined for diagnosis of EONS,the AUC,sensitivity and specificity were 0.858,92.00％ and 93.10％,respectively.Conclusion Serum level of sTREM-1 in early stage is valuable for diagnosis of EONS,and the combined use of serum sTREM-1 and IL-6 may improve the diagnostic value.

Objective To determine how the pulmonary ligament affects the helical CT appearances of the lower thoracic disease on the basis of the anatomic findings. Methods Four cadavers were cut transversely, with the section thickness of 11.3-13.4 mm. 57 patients with the lower thoracic disease were scanned using Somatom Plus 4, with administration of intravenous contrast material. The correlation of the anatomic findings of the pulmonary ligament and the helical CT appearances of the lower thoracic disease was evaluated. Results On cadaver sections, the right pulmonary ligament attached the lower lobe of the right lung to the esophagus, while the left ligament attached the lower lobe of the left lung to the esophagus or the descending aorta. In 40 pleural effusion and 7 pneumothorax cases, the pulmonary ligament tethered the medial aspect of the collapsed lower lobe and limited the shift of the lower lobe. In 40 pleural effusions, the ligament divided the medial pleural space into an anterior and a posterior compartment. The ligament showed thickness due to the invasion of the lesions of lower lobe including 7 tumors and 3 inflammatory diseases. Conclusion The pulmonary ligament can affect the helical CT appearances of the lower thoracic disease, such as lobe collapse, pleural effusion and pneumothorax; while the intraparenchymal and mediastinal abnormality can extend into the pulmonary ligament.
