Objective:To study the antitumor effect and mechanism of cocultured CIK cells modified with IL-24 gene and autologous DCs on HL-60 cells in vitro.Methods:DCs and CIK cells were prepared routinely from human peripheral blood mononuclear cells ( PBMC).IL-24 gene was transferred into CIK cells via electroporation.The cells obtained were named CIK-IL24.RT-PCR and ELISA were used to evaluate expression of IL-24 gene in transfected CIK cells.The phenotypic changes of CIK cells were identified by flowcytometry analysis.The concentration of IFN-γ and TNF-α in supernatant of CIK was determined by ELISA.FCM was used to determine the cytotoxicity of cocultured CIK cells modified with IL-24 gene and autologous DCs against HL-60 cells.Results:Eukaryotic expressing plasmid pcDNA3.0-IL24 was transferred into CIK cells successfully via electroporation.The expressing rate of CD3~+、CD3~+CD56~+ cells had no significant change in CIK cells.However,the rate of CD4~+CD25~+ cells was significantly decreased compared with that of the control group.Expression of adhesion molecules CD54,CXCR4 were significantly increased on CD3+CD56+ cells.CIK-IL24 cells produced markedly higher levels of IFN-γ and TNF-α as compared with the CIK cells.By comparison with non-transfected CIK cells co-cultured with DCs,transfected CIK cells co-cultured with DCs had a significantly higher lytic activity against HL-60 cells.Conclusion:IL-24 gene modification can enhance the anti-tumoral immunity of CIK cells,the mechanism of which might be related to the increased secretion of IFN-γ,TNF-α,up-regulation of adhesion molecule expression,and reduction of the rate of CD4~+CD25~+ cells in CIK cells.

Objective To investigate the characteristics of blood donors’psychological activity,take reasonable intervention measures to improve the success rate of blood donation recruitment and the ratio of repeated blood donation.Methods The data of blood donors’psychological activity was collected by distributing questionnaires randomly,and the psychological characteristics and worries were analysed.Results In terms of the blood donation purpose,there were 62.73% of the blood donors who donate blood for the first time and take the“utility psychological”as the principal thing.There were 76.01% of the blood donors who donate blood repeatedly and take the“dedication psychological”as the principal thing.In terms of wor-ries,there was 72.69% of the blood donors who donate blood for the first time and take the“safety of blood donation”as the principal thing.There was 77.91% of the blood donors who donate blood repeatedly and take the “service quality of blood donation”as the principal thing.Conclusion The success rate of blood donation recruitment and the ratio of repeated blood donation could be effectively improved by attaching importance to the psychological needs and worries of blood do-nors,by taking different psychological intervention measures strategies for different kinds of blood donors,and by meeting their needs and eliminating their worries.

Objective To study the antitumor effect and mechanism of co-cultured cytokine-induced killer(CIK) cells and autologous DC modified with IL-24 gene on A549 cells in vitro. Methods DC and CIK cells were prepared routinely from human peripheral blood mononuclear cells(PBMC). Recombinant adenovirus vector pAdEasy-1-pTrack-CMV-IL-24 was extracted from DH5α, it was lineared with Pac I and transfected into A293 cells, and then the IL-24 recombined adenovirus(Ad-IL-24) was obtained. Ad-IL-24 was used to infect DC. The cells obtained were named DC-IL-24. RT-PCR and ELISA were used to evaluate the expression of IL-24 gene in transfected DC. The phenotypes change of DC were identified by flow cytometry analysis, the concen-tration of IL-12 and TNF-α in supernatant of DC were determined by EIJSA. The ability of CIK producing per-forin was measured by homolysis method. FCM was used to determine the cytotoxicity of cocultured CIK cells and autologous DC modified with IL-24 gene to A549 cells. Results We obtained the high titre of Ad-IL-24.IL-24 gene was transfered into DC successfully via Ad-IL-24. The green fluorescence was observed on DC by fluorescence microscope. The expression rate of CD80, CD83, HI.A-DR, CD40, CXCR4 on DC-IL-24 was sig-nificantly increased compared with that of the control group. DC-IL-24 produced markedly higher levels of IL-12 and TNF-α as compared with DC. DC-IL-24 can enhance the ability of CIK cells producing perforin. On com-parison with non-transfected DC co-cultured with CIK cells, transfected DC co-cultured with CIK cells had a sig-nificantly higher lytic activity against A549 cells. Conclusion IL-24 gene modification can enhance the anti-tu-moral immunity of DC. The mechanism of which might be related to the increased secretion of IL-12 and TNF-α, up-regulation expression of co-stimulatory molecules and MHC Ⅱ class molecules on DC, promoting the acti-vation and maturation of DC, and then enhancing CIK cells to generate specific anti-tumoral immunity.

Background and purpose:Cancer-related pain is one of the most important symptoms of patients with advanced cancer. Chemotherapy sometimes induces peripheral neuropathy and pain. These symptoms seriously affect patients’ quality of life. Cancer pain assessment is now achieved by the subjective scales of patients, but lacking objective measurement. In this study, we used the neurotic electrophysiological method by way of PainVision system (PV system) to evaluate cancer pain quantitatively to detect and analyze degree of chemotherapy-induced neuropathy. Methods:We obtained numerical rating scale (NRS) scores from patients receiving analgesics and calculated the PainRatio from PV system at the same time. Then we analyzed the relationship between NRS and PainRatio scores. We detected current perception threshold (CPT) levels of patients receiving chemotherapy to ifnd the correlation between chemotherapy and CPT level, and attempt to evaluate chemotherapy-induced neuropathy.Results:PainRatio scores were linearly associated with NRS scores (Pearson correlation coeffcient=0.849,P<0.001). Patients with neuropathy symptoms got higher CPTs. However, no statistically signiifcant difference was observed between patients treated with oxaliplatin, paclitaxel and other agents.Conclusion:PainVision system can be used in cancer pain assessment quan-titatively, and be helpful in cancer pain assessment objectively. Patients with deifned neuropathy showed higher CPTs, indicating the potential clinical value of PV system in detecting and evaluating chemotherapy-induced neuropathy.

Objective:To investigate the diagnostic values of interleukin-22 (IL-22), interferon-γ(IFN-γ)and macrophage migration inhibition factor (MIF) in pleural effusion for tuberculosis pleurisy.Methods:From April 2018 to May 2019, a total of 77 patients including 45 cases of tuberculous pleurisy, 19 cases of malignant pleurisy, 13 cases of parapneumonia and 13 cases of healthy control in Wuxi Fifth People′s Hospital were enrolled. The levels of IL-22, IFN-γ and MIF in plasma and pleural effusion were detected by enzyme linked immunosorbent assay (ELISA). Mann-Whitney U test was used for statistical analysis.The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic values of IL-22, IFN-γ and MIF for tuberculous pleurisy. Results:The median levels of IL-22, IFN-γ, MIF and adenosine deaminase in 45 cases with pleural effusion in tuberculosis pleurisy group were 396.8 ng/L, 2 200.0 ng/L, 241.3 μg/L and 70.8 U/L, respectively, which were all significantly higher than 32 cases with non-tuberculosis pleurisy group, including 19 cases with malignant pleurisy and 13 cases with parapneumonia (52.8 ng/L, 232.3 ng/L, 179.6 μg/L and 17.0 U/L, respectively). The differences were all statistically significant ( U=179.000, 118.500, 287.000, 162.000, respectively, all P<0.05). The median levels of IL-22 and IFN-γ in plasma of tuberculosis pleurisy group were 20.0 ng/L and 45.9 ng/L, respectively, which were both higher than healthy control group (14.3 ng/L and 33.4 ng/L, respectively). The level of MIF was 96.2 μg/L, which was lower than healthy control (159.5 μg/L). The differences were all statistically significant ( U=74.000, 13.000 and 73.000, respectively, all P<0.05). The areas under ROC curve (AUC) of IL-22, IFN-γ and MIF in pleural effusion for the diagnosis of tuberculosis pleurisy were 0.876, 0.917 and 0.682, respectively.The sensitivities were 93.75%, 100.00% and 63.64%, respectively; the specificities were 82.22%, 91.11% and 65.85%, respectively. The median levels of IL-22 and IFN-γ in plasma in tuberculosis pleurisy group at two months of follow-up after anti-tuberculosis therapy were 16.0 ng/L and 33.9 ng/L, respectively, which were both lower than baseline (20.0 ng/L and 44.7 ng/L, respectively). The differences were both statistically significant ( U=2.156 and 2.221, respectively, both P<0.05). Conclusion:IFN-γ and IL-22 in pleural effusion could be used as effective indicators to identify tuberculous pleurisy, and the dynamic monitoring of IL-22 in patients′plasma could be an important biomarker in evaluating the efficacy of anti-tuberculosis treatment.

Objective: To introduce a new technique of angulated innominate osteotomy modified from Salter innominate osteotomy and to compare its early clinical effects with the traditional Salter technique. Methods: Data of 45 cases treated with innominate osteotomy from January 2015 to December 2016 were retrospectively analyzed. There were 14 cases (1 male and 13 females; average age 34.21 months, range from 20 to 43 months) treated by traditional Salter innominate osteotomy (the traditional group) and 31 cases (5 males and 26 females; average age 25.42 months, range from 17-42 months) treated by angulated innominate osteotomy (the modified group). The acetabular index was evaluated radiographically for assessing surgical effects. The operation time and total blood loss during the operation were also collected. McKay method was used for clinical evaluation at the last follow-up. The images of the follow-ups, including the latest one, were used to confirm the exist of complications of avascular necrosis of femoral epiphysis, re-dislocation or subluxation of the hip. Results: The mean follow-up time of traditional group was 23.64 months (range, 8-50 months) and modified group's was 18.94 months (range, 8-35 months). The mean time consumption of modified group (262.42±67.56 min) was significantly lower than traditional group's (306.43±48.37 min) (t=2.482, P=0.018) and the mean total amount of blood loss in the modified group was 81.28±29.00 ml, significantly lower than that of the traditional group's of 117.85±45.55 ml (t=2.762, P=0.013). All the involved hips in the two groups achieved varying degrees of deformities correction after surgery. In the traditional group, the mean correction angle was 13.19°±2.89°, compared to 15.46°±4.29° of the modified group's, and there was statistical differences (t=-2.078, P=0.045). As for McKay results, the excellent combined with good rates in the traditional group and the modified group were 86% and 90%, respectively. The occurrence rate of avascular necrosis of modified group was about 25.81% while traditional group's was 50%. Two patients had subluxation signs in the traditional group. Conclusion In this research, the angulated innominate osteotomy had good early outcomes with less blood loss and lower incidence of complications than the traditional one.

ObjectiveTo study the efficacy of Aclasta combined with Liuwei Dihuangwan on osteoporosis and the effect on quality of life. MethodA total of 126 patients with osteoporosis who were treated in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2019 to September 2020 were classified into the observation group and the control group with the randomized double-blind method. The observation group consisted of 60 patients （26 males and 34 females） with the age of 59-85 years old ［mean： （72.0 ± 6.5） years old］. The control group was composed of 66 patients （31 males and 35 females）， with the age of 62-82 years old ［mean： （73.0±8.2） years old］. The control group was treated with Aclasta， and the observation group Aclasta combined with Liuwei Dihuangwan. After treatment， the effective rate of each group was calculated. Bone mineral density （BMD） was measured in both groups before and after treatment， and serological parameters calcium （Ca）， total 25 （OH） vitamin D₃ （VITD-T）， osteocalcin （OC）， serum alkaline phosphatase （ALP）， parathyroid hormone （PTH）， β-collagen special sequence （β-CTX）， and total procollagen 1 N-terminal propeptide （T-P1NP） were also measured. Visual Analogue Scale （VAS） score， Japanese Orthopaedic Association （JOA） score， and Oswestry Disability Index （ODI） score were evaluated. On this basis， the effect was compared between the two groups. ResultThe indexes were insignificantly different between the two groups before treatment. After 6 months of treatment， the two groups showed decrease in VAS score and ODI score （P<0.01）， increase in JOA score （P<0.01）， BMD of lumbar spine and hip joint， elevation of Ca， VITD-T， OC， ALP， and PTH （P<0.05， P<0.01）， and decrease of β-CTX （P<0.01） as compared with before treatment. The level of T-P1NP dropped in the observation group after treatment （P<0.01）.After treatment， the total effective rate of the observation group was 88.3% （53/60）， as compared with the 74.2% （49/66） in the control group （χ²=4.047， P<0.05）. Moreover， after treatment， the observation group demonstrated higher levels of BMD， Ca， VITD-T， OC， and PTH （P<0.05）， lower levels of T-P1NP （P<0.05）， lower VAS score （P<0.01）， and higher JOA score （P<0.05） than the control group， but the ODI score was insignificantly different from that in the control group. ConclusionAclasta combined with Liuwei Dihuangwan is effective on osteoporosis， without increasing the incidence of adverse reactions. In addition， the combination can alleviate pain and improve the quality of life of osteoporosis patients.
