Objective To investigate the status and influencing factors of infusion-related adverse events in third-party cord blood stem cell infusion. Methods A total of 305 patients successfully underwent haploidentical stem cell transplantation combined with the third-party cord blood(CB) infusion,were recruited by convenience sampling from January 2013 to December 2015,in hematological department of a tertiary hospital in Suzhou. A self-developed questionnaire and adverse event assessment scale were used to investigate the influencing factors. Results The rate of infusion-related adverse events was 49.51%,81.82% were related to cardiovascular adverse events with the high-est rate of hypertension(76.14%). Logistic regression analysis showed that age(OR=1.030,95CI%:1.010-1.051),HLA matching between CB and receptor (OR=0.589,95%CI:0.413-0.838),thawed CB cell activity (OR=1.064,95%CI:1.015-1.115)were major influencing factors. Conclusion Nurses should pay attention to patients who are elderly,with low matching HLA and receive thawed CB product with high cell activities,and provide timely nursing care in advance.

Objective To observe the protective effect of N-NAC on radiation-induced lung injury. Methods 86 cases of thoracic neoplasm patients were chosen and randomly divided into two groups,group RT +N(n =43)and group RT(n =43).Two groups were observed by CT after radiotherapy.Acute and chronical toxicities were graded by RTOG.TGF-β1,IL-1,IL-4,TNF were observed before and after the radiotherapy.Results After 3 monthsof radiotherapy,RTOG≥2 was 23.4%(RT +N),while RTOG≥2 was 53.1%(RT).there was significant differencebetween the two groups(P <0.01).At 6,9 and 12 months,fibrosis was present in 28.4%,25.4%,22.4% receivingRT vs 58.4%,54.4%,52.4% receiving RT +N,there was significant difference between the two groups(P <0.05).TGF-β1,IL-1,IL-4,TNF were observed which showed that The RT +N were lower than RT.Conclusion N-NAC can reduce incidence rate of lung injury in radiotherapy,and can reduce the content and the release of TGF-β1,IL-1,IL-4,TNF.

Objective To evaluate the clinical efficacy of arthroscopic treatment with anchor fixation for Segond fractures.Methods A total of 29 patients with Segond fractures treated with arthroscopic evaluation and anchor fixation technique between January 2011 and December 2015 were included in this retrospective case series study.There were 17 males and 12 females,with an average age of 41 years (range,27-62 years).Among the patients with Segond fractures,there were 20 patients combined with anterior cruciate ligament (ACL) rupture,three with posterior cruciate ligament (PCL) rupture,seven with medial collateral ligament (MCL) lesion,six with lateral collateral ligament (LCL) rupture,12 with meniscus lesion,and two with tibial plateau fracture.The time duration from injury to operation was 5-14 days (mean,7 days).The operation time and intraoperative blood loss volume were recorded.The postoperative pain,complications,knee joint stability,and fracture healing were observed.The pain was evaluated using numerical rating scale (NRS).Drawer test,Lachman test,lateral stress test,and Lysholm scores were performed to assess the knee function before and after operation.Results The operation time was 40-125 minutes (mean,85 minutes),and intraoperative blood loss was 10-30 ml (mean,15 ml).All patients were followed up for 12-18 months (mean,14 months).Two weeks after operation,the pain was not obvious,with NRS of 0-1.One patient had deep venous thrombosis one week after operation,and recovered after vascular intervention therapy.Other patients had no infection,deep vein thrombosis or other postoperative complications.The results of drawer test,Lachman test,and lateral stress test were negative in all patients,which indicated good knee joint stability.All patients were seen bone union,with the healing rate of 100％.The preoperative Lysholm scores were 35-62 points [(52.0 ± 4.2) points],and the scores one year after operation were 86-95 points [(91.9 ± 1.4) points] (P ＜ 0.05).Conclusion Arthroscopic treatment with anchor fixation has advantages of minor trauma,little hemorrhage,high fracture healing rate and good function recovery,and hence is an effective surgical treatment for Segond fractures.

Objective To investigate the status and analyze the influencing factors of structural empowerment and psychological empowerment of midwives in Suzhou.Methods Using convenience sampling,totally 309 midwives from fifteen hospitals in Suzhou were investigated with the Conditions of Work Effectiveness Questionnaire-Ⅱ (CWEQ-Ⅱ) and Psychological Empowerment Scale (PES).Results The scores of structural and psychological empowerment of midwives were (18.07±3.12) and (14.82±2.01).There was a significantly positive correlation between midwives' structural and psychological empowerment (r=0.396,P＜0.01).Hospital level and whether participate in midwifery standardization training had an impact on structural empowerment score(P＜0.05).Age,parental status,job title,salary,delivery room working hours,number of night shifts per month,and whether or not participate in teaching had an impact on psychological empowerment score(P＜0.05).Conclusion Midwives' structural and psychological empowerments are at a moderate level.Administrators should take targeted intervention to create an empowerment-allowing working environment for midwives,stabilize midwives work force,strengthen midwifery discipline construction and make full specialized features of midwives.

Intracerebral hemorrhage is a kind of nervous system disease with high mortality and disability. By analyzing the clinical variables closely associated with the functional outcome of intracerebral hemorrhage, a scoring scale that can quickly predict the outcome of intracerebral hemorrhage is established, which is helpful to guide clinicians in risk stratification and clinical diagnosis and treatment of patients with intracerebral hemorrhage. At present, more than 10 clinical outcome scoring scales have been developed. This article summarizes these scoring scales of intracerebral hemorrhage in chronological order, and reviews their constituent variables, outcome evaluation value, and follow-up verification.

Objective To explore the efficacy of hematopoietic stem cell transplantation (HSCT) for 5 patients with Ph-like acute lymphoblastic leukemia (ALL).Methods Fluorescent in situ hybridization (FISH) was performed for detecting the rearrangement of susceptibility genes.Combined therapy of chemotherapy and ruxolitinib were applied,followed by HSCT.Those failing to achieve complete remission (CR) received an infusion of chimeric antigen T-cells (CAR-T),followed by HSCT once CR was achieved.Four patients accept allogenic HSCT while another auto HSCT.Results Three of them achieved CR after chemotherapy and ruxolitinib.The remaining 2 patients got CR after CAR-T.Four patients remained in CR after HSCT.Early relapse occurred in 1 patient after HSCT.Conclusions Combined therapy of chemotherapy,ruxolitinib and CAR-T are necessary for Phlike ALL patients.HSCT after an initial CR improve patient prognosis.

Ferroptosis is a new programmed cell death dependent on iron ions.Ferroptosis can be induced by endogenous or exogenous pathways, and cells exhibit specific cell morphological signs and are regulated by a variety of molecular mechanisms.In recent years, more and more studies have shown that ferroptosis plays an important role in the treatment of cancer.This article summarizes the mechanism of ferroptosis in bladder cancer and the regulation of cancer cells, as well as the role of ferroptosis-related factors, non-coding RNA regulation, N6-methyladenosine (m6A), amino acid metabolism and autophagy dependent ferroptosis in the growth and proliferation of bladder cancer, with a view to provide new strategies for the treatment of bladder cancer.

Inflammation-driven endothelial dysfunction is the major initiating factor in atherosclerosis, while the underlying mechanism remains elusive. Here, we report that the non-canonical stimulator of interferon genes (STING)-PKR-like ER kinase (PERK) pathway was significantly activated in both human and mice atherosclerotic arteries. Typically, STING activation leads to the activation of interferon regulatory factor 3 (IRF3) and nuclear factor-kappa B (NF-κB)/p65, thereby facilitating IFN signals and inflammation. In contrast, our study reveals the activated non-canonical STING-PERK pathway increases scaffold protein bromodomain protein 4 (BRD4) expression, which encourages the formation of super-enhancers on the proximal promoter regions of the proinflammatory cytokines, thereby enabling the transactivation of these cytokines by integrating activated IRF3 and NF-κB via a condensation process. Endothelium-specific STING and BRD4 deficiency significantly decreased the plaque area and inflammation. Mechanistically, this pathway is triggered by leaked mitochondrial DNA (mtDNA) via mitochondrial permeability transition pore (mPTP), formed by voltage-dependent anion channel 1 (VDAC1) oligomer interaction with oxidized mtDNA upon cholesterol oxidation stimulation. Especially, compared to macrophages, endothelial STING activation plays a more pronounced role in atherosclerosis. We propose a non-canonical STING-PERK pathway-dependent epigenetic paradigm in atherosclerosis that integrates IRF3, NF-κB and BRD4 in inflammatory responses, which provides emerging therapeutic modalities for vascular endothelial dysfunction.
