Objective To evaluate the efficacy of stent-assisted coiling in the treatment of unruptured vertebral dissecting aneurysm. Methods We retrospectively reviewed 59 consecutive patients with unruptured vertebral dissecting aneurysms that underwent endovascular treatment. 31 patients received single stent-assisted coiling, 28 patients received multiple stent-assisted coiling. Results Clinical outcome was favorable in 56 of the 59 patients, the modified Rankin Scale score had no difference in both groups (P = 0.24). The immediate obliteration grade in multiple-stent group was higher than that in single-stent group (75.0% vs. 41.9%, P=0.010). What′s more, the recurrence rate was lower in multiple-stent group (0% vs. 19.4%, P = 0.043). Conclusions Stent-assisted coiling in the treatment of unruptured vertebral dissecting aneurysm is safe and effective , multilayer disposition of stents with coils will decrease the complications and facilitate the aneurysmal occlusion. Larger , prospective studies are necessary to explore the long-term outcomes of reconstruction therapy.

Objective To investigate the epidemiology of viral infection in elderly patients to contract acute exacerbations of chronic obstructive pulmonary disease (AECOPD)in Minhang district of Shanghai from 2010 to 2012,and to study the relationships between viral infection and clinical features.Methods The elderly patients (age >70 year old)with AECOPD admitted from September 2010 to November 2012 were enrolled for study.The patients who couldn't complete lung function test were excluded.The pharyngeal swabs (PS)were taken from each patient within the first 24 h after admission.Nine respiratory viruses and their subtypes from pharyngeal swabs were detected by the nested multiplex polymerase chain reaction (PCR)method,including influenza virus A (FluA),2009 influenza A (H1N1 )virus (09FluH1 ), influenza virus B (FluB),respiratory syncytial virus A (RSVA)and B (RSVB),human coronavirus-229E (hCOV-229E),human coronavirus-NL63 (hCOV-NL63 ),human coronavirus-OC43 (hCOV-OC43 ), human coronavirus-HKU1 (hCOV-HKU1),human parainfluenza virus 1-4 (hPIV1-4),human adenovirus (hAdV),human boca virus (hBoV),human metapneumo-virus (hMPV)and human rhinovirus (hRV). According to the PCR results,all patients were divided into positive viral infection group and negative viral infection group.The relationships between viral infection and clinical features were analyzed.Results Sixty patients were eligible for study.Of them,14 patients were found to be positive for virus infection including a triple infected patient (FluB,hRV and hROV)and 46 patients were negative for virus infection.The viral pathogens detected in the positive viral group were:9 cases of hRV (15.00%),2 cases of hPIV (3.33%),2 cases of hCOV (3.33%),2 cases of FluB (3.33%)and 1 cases of RSV (1.67%).The mortality in the positive viral group was higher than that in the negative viral group.However,the other clinical characteristics between the two groups had no significant differences. Conclusions Human rhinovirus was the most common viral pathogen in elderly patients with AECOPD.Viral infection might be associated with the prognosis.However,the patients with viral infection are lack of specific clinical characteristics,therefore,the prompt diagnosis before careful study would be difficult.

Long non-coding RNAs (lncRNAs) are a group of non-coding RNAs with a length of over 200 nucleotides. Recently, studies have shown that lncRNAs can regulate gene expression at the epigenetic, transcriptional, and post-transcriptional levels, affect the proliferation, migration, and infiltration of tumor cells, and participate in the occurrence and development of benign and malignant proliferative skin diseases, such as keloids, hemangioma, squamous cell carcinoma and melanoma. This review summarizes roles of lncRNAs in the pathogenesis of benign and malignant proliferative skin diseases.

Objective:To investigate the expression of promyelocytic leukemia zinc finger (PLZF) in human peripheral blood with asthma and its clinical significance.Methods:Forty patients with stable asthma from May 2021 to October 2021 in the Department of Respiratory Medicine of the Shanghai Fifth People's Hospital were enrolled, and forty healthy controls were recruited in the study. The levels of cytokines in serum were measured by enzyme-linked immunosorbent assay (ELISA). Quantitative real-time PCR (qPCR) was used to detect the expression of PLZF mRNA in plasma. The level and distribution of PLZF+ cells in PBMCs were detected by flow cytometry after isolating peripheral blood mononuclear cells (PBMCs). Independent sample t test, Mann-Whitney U test, χ 2 test, ROC curve and Logistic regression were used to analyze the results with SPSS 26.0 and Graphpad Prism 7.0. A P<0.05 was considered statistically significant. Results:The levels of cytokines IFN-γ, IL-2, IL-4, TNF-α and IL-17 in human peripheral blood from the asthma group were obviously higher than those in the control group ( P<0.05), whereas there was no significant difference in the level of cytokine IL-10 between the two groups. The level of PLZF mRNA in PBMCs from the asthma group was significantly up-regulated compared to that in the control group [(3.40%±2.52%) vs. (1.23%±0.78%), P<0.05]. CD8+PLZF+ and Vβ11+PLZF+T cells in the asthma group were significantly outnumbered than those in the control group ( P<0.05). Logistic regression and ROC curve analysis showed that PLZF expression in PBMC was a risk factor for the development of asthma ( OR =3.67, AUC=0.87, P<0.05). Conclusions:The high expression of PLZF in peripheral blood may play an important role in the development of asthma, which needs to be further confirmed by large sample studies.

【Objective】 To explore the safety of RhD-positive red blood cells (RBCs) immunization schedules in RhD-negative volunteers, so as to facilitate the development of domestic anti-D immunoglobulin. 【Methods】 From January 2018 to April 2020, 23 RhD negative volunteers with informed consent were enrolled and divided into initial immunization group and booster immunization group. The initial immunization included first immunization, second immunization and third immunization. Four groups, i. e. 3 cases of 20 mL, 8 of 30 mL, 6 of 40 mL, and 6 of 50 mL, were involved in initial immunization. After the initial immunization response, booster immunizations were performed every 3 months. According to the anti-D titer before each immunization, the booster immunization doses were set to 0.5, 1 and 2 mL. Whole blood samples of 5mL/ person (time) were collected 24 h and 1 week after each infusion, and the blood routine, liver, kidney and blood coagulation function and anti-D titer were detected. The differences of detection (index) values at 24 h and 1 week after the first immunization and booster immunization in each (dose) group were compared. 【Results】 No statistically significant differences were observed in hemolysis index values (all within the range of medical reference values) 24 h or 1 week after initial immunization among RhD positive RBCs of 20, 30, 40 and 50mL(P>0.05). The differences between the hemolysis index values and the basic values before the immune response (all within the range of medical reference values) after 0.5 or 1 mL booster immunizations were also not statistically different (P>0.05). However, the differences (μmol/L)between total bilirubin levels and the basic values before the immune response (1.55±1.87, 6.29±2.66) were significantly different after 2 mL booster immunization (P<0.05). 【Conclusion】 No risks affecting the safety of RhD negative volunteers was found in the immunization schedule proposed in this study.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
