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.

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) (
