Objective To explore the effects of enhancing confidence of active cycle of breathing technique training on pulmonary rehabilitation in elder lung cancer patients with lung resection.Methods The control group (n=35) received routine breathing exercise from September to December 2016;the intervention group (n=35) received the confidence-enhancing active cycle of breathing technique in addition to routine perioperative care from January to April 2017.We compared the 24-hours wet sputum weight,postoperative pulmonary complications,the peak expiratory flow(PEF),6-minute walk test(6MWT),and exercise self-efficacy from baseline until hospital discharge.Results The sputum weight of postoperative on day 2 and day 3 in the intervention group were significantly higher than those in the control group(P＜0.05).The PEF,6MWT and exercise self-efficacy were also improved and the differences between two groups were statistically significant(P＜0.05).However,there was no significant difference in postoperative pulmonary complications between two groups (P＞0.05).Conclusion Confidence-enhancing active cycle of breathing technique is a simple,effective and easy short-term pulmonary rehabilitation method.

Objective: To investigate the causes of peripheral vascular thrombosis in patients with paraquat poisoning. Methods: The patients with paraquat poisoning who were admitted to our department in recent two years were observed to screen out the patients with large vessel thrombosis. The data on toxic exposure history, clinical features, and treatment were collected to analyze the causes of thrombosis in the patients with paraquat poisoning. Results: Three patients had typical lower limb thrombosis. There was one case of right common femoral vein thrombosis, one case of bilateral calf muscle vein thrombosis, and one case of right calf superficial vein thrombosis and right calf muscle vein thrombosis. Conclusions After paraquat poisoning, the blood is in a hypercoagulable state and prolonged bed rest may increase the risk of thrombosis.

Objective: To investigate an incident of mushroom poisoning and related clinical data. Methods: A descriptive analysis was performed to investigate an incident of poisonous mushroom poisoning in Jinan, Shandong Province, China in July 2016. The clinical data of four patients were analyzed and summarized, and the causes of this incident and prevention and control measures were summarized. Results: This incident of acute poisonous mushroom poisoning was caused by Lepiota brunneoincarnata. The patients mainly had digestive system symptoms, including nausea, vomiting, and severe abdominal pain, and later developed liver damage. After comprehensive rescue treatment, one patient died and three survived. The main clinical manifestation of the patient who died was multiple organ failure, especially liver failure. Conclusion This incident of poisoning was caused by Lepiota brunneoincarnata the residents ate by mistake.

Objective: To explore the acute toxicity of Diquat in mice and to calculate the median lethal dose (LD₅₀) of Diquat to rats and observe the pathological changes of tissues and organs in rats with different concentrations of Diquat. Methods: Diquat solution of 50 mg/kg was prepared freshly with 1 000 mg of Diquat and dilute the solution with water to a total of 20 ml. A total of 99 healthy adult male Wistar rats were randomly divided into part one, part two and control groups. In the first part, 36 rats were randomly divided into 4 groups: 100 mg/kg group, 200 mg/kg group, 300 mg/kg group and 400 mg/kg group, which were treated with 100 mg/kg, 200 mg/kg, 300 mg/kg and 400 mg/kg of Diquat solution by gavage, respectively. The death and symptoms of poisoning after intragastric administration were recorded, and the maximum tolerated dose and absolute lethal dose were measured. In the second part, 54 rats were randomly divided into 6 groups: 200 mg/kg group, 220 mg/kg group, 240 mg/kg group, 260 mg/kg、280 mg/kg group and 300 mg/kg group, whichwere treated with 200 mg/kg, 220 mg/kg, 240 mg/kg, 260 mg/kg, 280 mg/kg and 300 mg/kg of Diquat solution by gavage, respectively. The survival of rats in different concentration of Diquat was observed and the LD₅₀ was calculated by Excel processing the formula of Koch's method. The control group were given equal volume water under the same experimental conditions. And moreover, the lungs, kidneys, hearts, livers, and brain tissues were collected and fixed by formaldehyde, embedded by paraffin, and sectioned for histopathological light microscopy. Results: The maximum tolerated dose was 240 mg/kg and the absolute lethal dose was 300 mg/kg. The LD₅₀ of Diquat for Rats was 280.58 mg/kg. The high-dose group had significantly more organ damage than the low-dose group after diquat poisoning. Conclusion The determination of the half-lethal dose of diquat, at the same time observed multiple organs damaged in rats after the diquat quickly poisoned. Kidneys, lungs and heart might be the main organ which was heavily damaged. With the extension of observation time, the organ damage of rats exposed to small doses gradually stabilized.

The generation of T cells with maximal anti-tumor activities will significantly impact the field of T-cell-based adoptive immunotherapy. In this report, we found that OKT3/IL-2-stimulated T cells were phenotypically more heterogeneous, with enhanced anti-tumor activity in vitro and when locally administered in a solid tumor mouse model. To further improve the OKT3/IL-2-based T cell manufacturing procedure, we developed a novel T cell stimulation and expansion method in which peripheral blood mononuclear cells were electroporated with mRNA encoding a chimeric membrane protein consisting of a single-chain variable fragment against CD3 and the intracellular domains of CD28 and 4-1BB (OKT3-28BB). The expanded T cells were phenotypically and functionally similar to T cells expanded by OKT3/IL-2. Moreover, co-electroporation of CD86 and 4-1BBL could further change the phenotype and enhance the in vivo anti-tumor activity. Although T cells expanded by the co-electroporation of OKT3-28BB with CD86 and 4-1BBL showed an increased central memory phenotype, the T cells still maintained tumor lytic activities as potent as those of OKT3/IL-2 or OKT3-28BB-stimulated T cells. In different tumor mouse models, T cells expanded by OKT3-28BB RNA electroporation showed anti-tumor activities superior to those of OKT3/IL-2 T cells. Hence, T cells with both a less differentiated phenotype and potent tumor killing ability can be generated by RNA electroporation, and this T cell manufacturing procedure can be further optimized by simply co-delivering other splices of RNA, thus providing a simple and cost-effective method for generating high-quality T cells for adoptive immunotherapy.

Objective:To detect the expression of tumor necrosis factor alpha in (TNF alpha) breast cacner and its relationship with imaging features.Methods:Using immunofluorescence and flow cytometry to detect the expression of TNF-α in MDA-MB-231 and MCF-7.Collect 82 patients with mammary gland disease,which was confirmed by pathological tissue,its pathological data,imaging data,and by immunohistochemistry to detect the expression of TNF-α in breast tissues,and analyze and the relationship between its expression and the pathological features and imaging characteristics.Results:TNF-α high expression in MDA-MB-231,the expression of TNF-oα in malignant breast tumor tissue significantly higher than that in benign tumor,the expression quantity associated with lymph node metastasis,TNM stages,strengthen uniform in MRI,the boundary and the shape of the X-ray Mammography (P=0.01),and color flow signal strength in ultrasound (P＜0.05).Conclusions:TNF alpha in breast tumor tissue was unusually high expression,and is closely related to some of the imaging features of breast tumor.

Objective To evaluate the psychometric characteristics of the Chinese version of Cataldo Lung Can cer Stigma Scale (CLCSS). Methods Convenience sampling was used to recruit 775 lung cancer patients in a tertiary hospital and some anticancer groups in Beijing,and the Chinese version of CLCSS was used to perform measure-ment. Results The S-CVI/UA was 0.87,and S-CVI/Ave was 0.96. Construct validity consisted of EFA and CFA. Through EFA,the Chinese version of CLCSS included four dimensions which accounted for 55.248% of the accu-mulated variance. Through CFA,all the indicators were in adaptation standard range. The test-retest reliability for the Chinese version of CLCSS was 0.801(P<0.01). Cronbach's α coefficient was 0.932,and Cronbach's α coeffi-cients for four dimensions ranged from 0.799 to 0.922. Conclusion The reliability and validity of the Chinese version of CLCSS are satisfactory and the Chinese version of CLCSS can be used among Chinese lung cancer patients.
