Objective To observe the effect of aspirin intervention on thrombosis in lung cancer patients with peripherally inserted central catheter (PICC).Methods From December 2007 to June 2012,a total of 997 cases of lung cancer received PICC insertion in Shanghai Chest Hospital.The patients admitted from December 2007 to October 2011 were in the control group (n =562),while those admitted from November 2011to June 2012 were in the intervention group (n =435).The control group received conventional catheterization and saline tube sealing; the study group was treated with the modified Seldinger technique,oral administration of aspirin enteric tablets,and diluted heparin sodium tube sealing.Results The incidence of thrombosis was4.09% (23/562) in the control group and 2.99% (13/435) in the intervention group.In the control group,17 cases of thrombosis occurred within 1 week after catheter insertion,3 between 1 week to 1 month,and 3 after 1 month ; in the intervention group,4 cases of thrombosis occurred within 1 week after catheter insertion,5between 1 week to 1 month,and 4 after 1 month,presenting a significant difference compared with the control group (Z =-2.221,P =0.026).A significant intergroup difference was also observed in terms of thrombus location (Z =-2.066,P =0.039):in the control group,17 cases had thrombus in peripheral superficial vein,and 6 in supraclavicular vein or internal jugular vein; while in the intervention group,5 cases had thrombus in peripheral superficial vein,and 8 in supraclavicular vein or internal jugular vein.Conclusion The prophylactic oral administration of aspirin could effectively reduce the thrombosis in lung cancer patients treated with chemotherapy via PICC.

Osteoarthritis (OA), a chronic joint degenerative disease, is the significant cause of the loss of joint function in middle-aged and older people. Bone destruction, synovial hyperplasia, osteophyte formation, and subchondral bone sclerosis are the main features of osteoarthritis, and the typical symptom is severe joint pain. Consequent to unprecedented global population aging, osteoarthritis remains a leading cause of disability, and the treatment often comes at a high cost. With an in-depth understanding of related research, osteoarthritis is proven to be a multifactorial disease whose onset is not simply a cartilage lesion, and the immune plays an essential role in the development of the disease. Some studies proposed that chondrocytes are capable of altering gene expression and mediating osteoarthritis progression by regulating immune responses. Previous studies showed that the extent of immune dysregulation significantly correlates with the severity of osteoarthritis, revealing an association between immunity response and clinical manifestations. The study of immune infiltration, genetic alterations, and pathogenesis of osteoarthritis may provide new perspectives and methods for the treatment of osteoarthritis in the future. Therefore, this review, combined with the recent decade of literature, provides an overview of the research progress of the main immune cells and related cytokines in OA, which may provide a new direction of thinking for diagnosing and preventing this disease.

Objective To investigate the optimal self care in lung cancer patients with peripherally inserted central catheter (PICC) in ladder-type nursing training,network education,continuing nursing care clinics,and other forms of nursing mode care.Methods Based on the baselien data of patients in the control group and observation group,PICC self management ability,PICC quantitative data,PICC-related infections,thrombosis,and other complications were compared,and the impact of continued nursing platform on lung cancer patients with indwelling PICC was analyzed.Results In the observation group self management ability and health behavior is higher than that of the control group (P<0.001).PICC catheter -related complications no difference with the control group (P>0.05),Patient satisfaction of the observation group than the control group,the difference was statistically significant (92.18% vs.79.00%,P=0.015).Conclusion The self care based on the continued nursing mode established by PICC speciality nurses can improve the self-management level of patients with PICC,reduce PICC-related complications,and increase the patient's satisfaction.

Objective To investigate the expression of oxytocin ( OXT ) and oxytocin receptor (OXTR) in the prefrontal cortex of postpartum depression (PPD) rats induced by restraint stress during pregnancy and to observe the antidepressant effect of oxytocin and its analogue capitoxin and its mechanism. Methods Twenty-four adult female SD rats of SPF grade were randomly divided into control group,PPD +saline group,PPD + oxytocin group and PPD + captopril group with 6 rats in each group. Rats were subjec-ted to restraint stress for 2 hours every day on the 8th to 21st day of pregnancy to establish PPD model. While the rats in control group were not given any treatment. Rats in PPD + saline,PPD + oxytocin and PPD +captopril were injected bilaterally into prefrontal cortex (PFC) at 10 days postpartum (1 μl/side),oxytocin (30 ng/side) and captopril (45 ng/side) respectively once a day for 5 days. The depressive behaviors of rats were detected by sugar-water preference experiment. Rats were sacrificed 18 days after delivery. The ex-pression of OXT was detected by ELISA method,OXTR by Western blot,Iba-1 by immunofluorescence,and IL-1β,IL-6 and TNF-α by qRT-PCR. Results (1) The sucrose consumption of the PPD + saline group ((67. 1±10. 4)%) was significantly lower than that of the control group((92. 6± 3. 9)%,t=-5. 31,P<0. 01). (2) The expression of oxytocin in prefrontal cortex in PPD group was significantly lower than that in control group ((0. 03±0. 01) ng/mg) vs (0. 08 +0. 05) ng/mg,t=-2. 67,P<0. 05). However,there was no significant difference in the expression of oxytocin receptor between PPD group and control group ((0. 90 ±0. 06) vs (0. 90±0. 05),t=0. 709,P=0. 517). (3) The sucrose consumption of PPD+saline group de-creased than that of control group((65. 6±16. 9)% vs (91. 5±3. 5)%,t=3. 35,P<0. 001). Compared with PPD+saline group,the sucrose consumption of PPD+oxytocin group ((81. 8±8. 4)%) and PPD+carbetocin group ((78. 4±9. 4)%) increased(t=1. 98,1. 68,both P<0. 05). (4) The expression of Iba-1 in the pre-frontal lobe of PPD + saline group was higher than that of control group ((1. 15±0. 05) vs (1. 04 +0. 06), t=3. 50,P<0. 01). Compared with PPD + saline group,the expression of Iba-1 in PPD + oxytocin group (1. 03±0. 06) and in PPD + captopril group (1. 00±0. 02) were lower (t=-3. 50,-6. 55,both P<0. 01). (5) The expression of inflammatory factors IL-1β mRNA (1. 0±0. 1),IL-6 mRNA (1. 1±0. 1) and TNF-α mRNA (1. 7±0. 4) in the prefrontal cortex of rats in the PPD group were higher than that in the control group (IL-1β mRNA (0. 7± 0. 3),IL-6 mRNA (0. 9± 0. 1),TNF-α mRNA ( 1. 1± 0. 3),t=1. 92,3. 19, 2. 43 respectively,all P<0. 05). The expression of inflammatory factors IL-1β,IL-6 and TNF-α mRNA of the PPD+oxytocin group(IL-1β mRNA (0. 6±0. 1),IL-6 mRNA (0. 9±0. 1),TNF-α mRNA (1. 2±0. 4) )and the PPD+carbetocin group ( IL-1β mRNA ( 0. 7± 0. 1),IL-6 mRNA ( 0. 9 ± 0. 1),TNF-α mRNA ( 1. 0 ± 0. 2))in the prefrontal cortex were lower than that in the PPD group(t=-3. 17,-2. 78,-1. 84,t=-2. 76,-2. 40,-2. 94 respectively,all P<0. 05). Conclusion Oxytocin and capitoxin injected into prefrontal cortex can effectively improve depression-like behaviors in PPD model rats. Activation of microglia and decrease of inflammatory factors in prefrontal cortex may be the potential antidepressant mechanism.
