OBJECTIVE@#This study summarizes and compares clinical and laboratory characteristics of 34 patients admitted to the intensive care unit (ICU) for complications from coronavirus disease 2019 (COVID-19) at the First Affiliated Hospital, School of Medicine, Zhejiang University, Hangzhou, China from Jan. 22 to Mar. 5, 2020.@*METHODS@#A total of 34 patients were divided into two groups, including those who required noninvasive ventilation (NIV) and invasive mechanical ventilation (IMV) with additional extracorporeal membrane oxygenation (ECMO) in 11 patients. Clinical features of COVID-19 patients were described and the parameters of clinical characteristics between the two groups were compared.@*RESULTS@#The rates of the acute cardiac and kidney complications were higher in IMV cases than those in NIV cases. Most patients had lymphocytopenia on admission, with lymphocyte levels dropping progressively on the following days, and the more severe lymphopenia developed in the IMV group. In both groups, T lymphocyte counts were below typical lower limit norms compared to B lymphocytes. On admission, both groups had higher than expected amounts of plasma interleukin-6 (IL-6), which over time declined more in NIV patients. The prothrombin time was increased and the levels of platelet, hemoglobin, blood urea nitrogen (BUN), D-dimer, lactate dehydrogenase (LDH), and IL-6 were higher in IMV cases compared with NIV cases during hospitalization.@*CONCLUSIONS@#Data showed that the rates of complications, dynamics of lymphocytopenia, and changes in levels of platelet, hemoglobin, BUN, D-dimer, LDH and IL-6, and prothrombin time in these ICU patients were significantly different between IMV and NIV cases.

Efficacy and safety of the long-acting fusion inhibitor albuvirtide in antiretroviral-experienced adults with human immunodeficiency virus-1: interim analysis of the randomized, controlled, phase 3, non-inferiority TALENT study / 中华医学杂志(英文版)

BACKGROUND@#Albuvirtide is a once-weekly injectable human immunodeficiency virus (HIV)-1 fusion inhibitor. We present interim data for a phase 3 trial assessing the safety and efficacy of albuvirtide plus lopinavir-ritonavir in HIV-1-infected adults already treated with antiretroviral drugs.@*METHODS@#We carried out a 48-week, randomized, controlled, open-label non-inferiority trial at 12 sites in China. Adults on the World Health Organization (WHO)-recommended first-line treatment for >6 months with a plasma viral load >1000 copies/mL were enrolled and randomly assigned (1:1) to receive albuvirtide (once weekly) plus ritonavir-boosted lopinavir (ABT group) or the WHO-recommended second-line treatment (NRTI group). The primary endpoint was the proportion of patients with a plasma viral load below 50 copies/mL at 48 weeks. Non-inferiority was prespecified with a margin of 12%.@*RESULTS@#At the time of analysis, week 24 data were available for 83 and 92 patients, and week 48 data were available for 46 and 50 patients in the albuvirtide and NRTI groups, respectively. At 48 weeks, 80.4% of patients in the ABT group and 66.0% of those in the NRTI group had HIV-1 RNA levels below 50 copies/mL, meeting the criteria for non-inferiority. For the per-protocol population, the superiority of albuvirtide over NRTI was demonstrated. The frequency of grade 3 to 4 adverse events was similar in the two groups; the most common adverse events were diarrhea, upper respiratory tract infections, and grade 3 to 4 increases in triglyceride concentration. Renal function was significantly more impaired at 12 weeks in the patients of the NRTI group who received tenofovir disoproxil fumarate than in those of the ABT group.@*CONCLUSIONS@#The TALENT study is the first phase 3 trial of an injectable long-acting HIV drug. This interim analysis indicates that once-weekly albuvirtide in combination with ritonavir-boosted lopinavir is well tolerated and non-inferior to the WHO-recommended second-line regimen in patients with first-line treatment failure.@*TRIAL REGISTRATION@#ClinicalTrials.gov Identifier: NCT02369965; https://www.clinicaltrials.gov.Chinese Clinical Trial Registry No. ChiCTR-TRC-14004276; http://www.chictr.org.cn/enindex.aspx.

Clinical and pathological features of idiopathic membranous nephropathy with phospholipase A2 receptor negative and serum anti PLA2R antibody negative: 40 cases analysis / 中国实用内科杂志

OBJECTIVE: To investigate the clinicopathological features of phospholipase A2 receptor(PLA2R) negative patents with idiopathic membranous nephropathy(IMN). METHODS: IMN patients diagnosed by renal biopsy were enrolled in this study. Glomerular PLA2 R deposition(GAg) and serum anti-PLA2 R antibodies(SAbs) were detected by immunohistochemical staining and enzyme linked immunosorbent assay, respectively. Patients were divided into two groups. Both GAg and SAbs were negative in patients of Group A. Patients of group B were selected from patients who were positive for GAg and SAbs and were matched with group A in gender and age. The clinical and laboratory data of the two groups were collected. Glomerular thrombospondin type-1 domaincontaining 7A(THSD7A) deposition and serum anti-THSD7 A antibody were also measured by immunohistochemical staining and indirect immunofluorescence in the two groups, respectively. RESULTS:(1) Compared with group B, patients in group A had lower levels of proteinuria, lower proportion of microscopic hematuria, higher remission rate(P<0.05). The positive rate of IgG4 in group A(45.0%) was significantly lower than that in group B(85.0%)(P<0.01).(2) The positive rate of glomerular THSD7 A deposition and serum anti-THSD7 A antibody of group A were 17.5% and 7.5%. Patients in group B showed negative THSD7 A tissue staining and antiTHSD7 A antibodies. CONCLUSION: Compared with patients who were positive for GAg and SAbs, patients who were negative for GAg and SAbs exhibited lower levels of proteinuria and higher remission rate. The positive rate of glomerular THSD7 A deposition and serum anti-THSD7 A antibody was low in patients with IMN.

Cultivation, screening, identification and transplantation of Muse cell from human umbilical cord-derived for spinal cord injury in rats / 中国骨伤

OBJECTIVE@#To investigate multilineage-differentiating stress-enduring (Muse) by immunomagnetic bead screening from Wharton's jelly mesenchymal stromal cells(WJ-MSCs), and explore transplantation of Muse cell for safety and effectivensess of sub acute cord injury in rats.@*METHODS@#Donated Wharton's Jelly-mesenchymal stromal cells (WJ-MSCs) were successfully derived from a human umbilical cord by a series of procedures namely physical isolation of Wharton's Jelly from cord membrane, collagenase and trypsin treatment and density gradient centrifugation. Magnetic activated cell sorting was performed to specifically select SSEA3+ Muse cells, and flow cytometry and immunocytochemistry were used to identify further. In vivo, spinal cord contusion injury model in rats was induced by NYU-III impactor, and were randomly divided and equally into four groups, namely group A (sham), group B (control), group C (Non-Muse cells transplantation) and group D (Muse cells transplantation). Laminectomy was conducted in group A but no spinal cord contusion injury. Laminectomy and cord injury were performed in group B, C and D, 10 g trip rod was freely falling down from 12.5 mm. Two weeks later, group B, C and D were received PBS injection, Non-Muse cells transplantation and Muse cells transplantation respectively, four-point injection were performed in each cord with totally 4×10⁵ cells. BBB scores were evaluated on 1 day, 1, 2, 3, 4, 5 and 6 week after injury. Four weeks after cell transplantation, the rats were sacrificed, and immunohistochemistry were carried out to observe survival, migration and differentiation of the injected cells.@*RESULTS@#The expression of CD105, CD90 and CD73 were over 99.5% in the derived WJ-MSCs population, but CD45 and CD14 were lower than 0.5%, positive rate of SSEA3+ was 1.46% under flow cytometer, However, after MACS sorting, the percentage of 92.0% Muse cells expressed SSEA3 and CD105, and immunohistochemistry results of SSEA3 showed typically membrane morphology with special processes. In vivo, BBB scores was 21 in group A at different time points. One-way ANOVA and LSD analysis showed that BBB scores in group C and D were significantly higher than that in group B (=0.004, 0.002), but there was no significantly difference between group C and D. Further intra-group paired t test showed that BBB score was significantly higher at 4 weeks than that 3 weeks in group C (=0.005). However, in group D, BBB scores were significantly higher at 4 and 6 week than those at 3 and 5 weeks, values were 0.005 and 0.016 respectively. Immunohistochemistry results showed that both Muse cells and Non-Muse cells could survive for 4 weeks in rats and they migrated from the four-point injection to injury site. But there showed more Muse cells survival than Non-Muse cells in the cord.@*CONCLUSIONS@#Immunomagnetic bead screening is efficient to select large number of purified SSEA3+ Muse cells. Muse cells could survive and target-migrate in injured cord to improve BBB scores continuously. Muse cells are a novel kind of seed cells in the spinal cord injury treatment.

Purinergic 2X7 Receptor is Involved in the Podocyte Damage of Obesity-Related Glomerulopathy via Activating Nucleotide-Binding and Oligomerization Domain-Like Receptor Protein 3 Inflammasome / 中华医学杂志(英文版)

Background@#The nucleotide-binding and oligomerization domain-like receptor protein 3 (NLRP3) inflammasome composed of NLRP3, apoptosis-associated speck-like protein containing CARD (ASC), and caspase-1 is engaged in the inflammatory response of many kidney diseases and can be activated by purinergic 2X7 receptor (P2X7R). This study was conducted to explore whether P2X7R plays a pathogenic role in the podocyte damage of obesity-related glomerulopathy (ORG) and whether this role is mediated by the activation of NLRP3 inflammasome.@*Methods@#A mouse model of ORG was established by high-fat diet feeding. The conditionally immortalized mouse podocytes were cultured with leptin or with leptin and P2X7R antagonist (KN-62 or A438079). The mRNA and protein expression of the P2X7R and NLRP3 inflammasome components including NLRP3, ASC, and caspase-1, as well as the podocyte-associated molecules including nephrin, podocin, and desmin in mouse renal cortex or cultured mouse podocytes were tested by real-time-polymerase chain reaction and Western blot analysis, respectively.@*Results@#The significantly upregulated expression of P2X7R and NLRP3 inflammasome components and the NLRP3 inflammasome activation were observed in the renal cortex (in fact their location in podocytes was proved by confocal microscopy) of ORG mice in vivo, which were accompanied with the morphological changes of podocyte damage and the expression changes of podocyte-associated molecules. Similar changes in the expression of P2X7R and NLRP3 inflammasome components as well as in the expression of podocyte-associated molecules were also observed in the cultured podocyte studies treated by leptin in vitro, and all of the above changes were significantly attenuated by the P2X7R antagonist KN-62 or A438079.@*Conclusions@#P2X7R could trigger the activation of NLRP3 inflammasome, and the activated P2X7R/NLRP3 inflammasome in podocytes might be involved in the podocyte damage of ORG.

Translocator protein mediated anti-PTSD effects of YL-IPA08 / 军事医学

Objective To explore the role of 18 ku translocator protein (TSPO) in the anti-post-traumatic-stress-disorder(PTSD) effects of YL-IPA08 and the value of TSPO as a potential pharmacological target using gene knock out mice.Methods The PCR method was used to genotype TSPO wild type (WT) mice and knock out (KO) mice.Foot shock was used to establish a well-accepted mouse model of PTSD,the open field test (OFT) was used to evaluate the locomotor activity in mice,and freezing measurement was used to evaluate the PTSD-like fear behavior in mice.Results Compared with TSPO WT mice,KO mice had no expressible TSPO gene,but showed similar locomotor activity to WT mice after PTSD modeling.On day 1,day 5 and day 16 after PTSD modeling (day-1-day 0),both WT and KO mice showed significant PTSD-like behavior with enhanced freezing time.However,8 d treatment (day 0-day 7) of YL-IPA08 (0.3 mg/kg,once daily) or positive drug sertraline (15 mg/kg,once daily) after PTSD modeling significantly reduced freezing time selectively in WT mice,but not in KO mice.Conclusion It has been found for the first time that TSPO WT and KO mice can show the same sensitivity to PTSD modeling (namely the same PTSD-like behavior performance).Interestingly,TSPO can mediate the anti-PTSD effects of YL-IPA08.Therefore,the present study provides direct evidence for the value of TSPO as an potential pharmacological target for PTSD.

Anti-post-traumatic-stress-disorder effects of YL-IPA08, a selective 18kDa translocator protein ligand / 国际药学研究杂志

Objective To explore the anti-post-traumatic-stress-disorder(anti-PTSD)effects of YL-IPA08,a selective 18kDa translocator protein(TSPO)ligand.Methods The time-dependent stress sensitization(TDS)method was used to establish a rat mod?el of PTSD.The open field test(OFT)was used to evaluate the locomotor activity in rats.The contextual freezing(CF)measurement, elevated plus maze(EPM)test and novel objective recognition(NOR)test were used to evaluate the PTSD-like behaviors in rats.The concentration of allopregnanolone in rat hippocampus was detected by ELISA. Results Compared with the control group,neither TDS nor drug treatment affected the locomotor activity in rats(P>0.05).However,PTSD rats showed significant PTSD-like behaviors with enhanced CF time in CF mearsurement,decreased open arm time and open arm entries in EPM test,and dropped object recogni?tion index in NOR test(P<0.05 or 0.01).Moreover,the concentration of hippocampus allopregnanolone was decreased in PTSD rats (P<0.05).YL-IPA08(0.05-0.1mg/kg)or positive drug sertraline(15 mg/kg),administered intragastrically after establishment of PTSD model,significantly reversed the above PTSD-like behavioral changes(P<0.05 or 0.01)and increased the concentration of hip?pocampus allopregnanolone in PTSD rats.Conclusion YL-IPA08 could improve the PTSD-like behavior in rats,and the mechanism may be related to the increased allopregnanolone level in hippocampus.

Relationship of pre-operative serum brain natriuretic peptide with risk of acute kidney injury after cardiac surgery / 第二军医大学学报

Objective To observe the relationship of pre-operative serum brain natriuretic peptide (BNP) with risk of acute kidney injury (AKI) after cardiac surgery. Methods We collected 182 patients undergoing cardiac surgery at Department of Cardiac Surgery, Changhai Hospital from Jan. 2012 to Jan. 2013. The surgical procedures included coronary artery bypass graft (CABG),valve replacement, and combined surgery (CABG+valve replacement). According to the preoperative BNP levels, the patients were divided into five groups in an ascending order. The definition and classification weres accorded to the latest AKI KDIGO (Kidney Disease: Improving Global Outcomes) guideline; the AKI incidence was obtained from patients with different BNP levels. Receiver operating characteristic (ROC) curves were used to evaluate the value of BNP level as a predictor of AKI. Results The average age of the 182 patients was (68.6±8.9) years old, with male being 65.9% (120/182). The surgery procedures including 82 CABG (45.0%),57 valve replacement (31.3%), and 43 combined surgery (CABG valve replacement) (23.6%). We found that age, basic renal function and pre-operative BNP levels were significantly different between the five BNP groups (P<0.05). The incidence of AKI was 33.5% (61/182) in this study. The incidence rates of stage 1 AKI and total AKI significantly increased with increase of BNP levels in the five BNP groups (P<0.05). As a predictor of AKI ROC curves, BNP area under the curve (AUC) was 0.687 (95% CI: 0.607-0.768). Conclusion Pre-operative BNP level is associated with post-operative AKI in high risk patients undergoing cardiac surgery, and it is a potential predictor of AKI risk stratification after cardiac surgery.

Objective To discuss the MRI features of sophorae subprostrate intoxication.Methods Four cases with sophorae subprostrate intoxication underwent conventional MRI and diffusion-weighted imaging(DWI)with a 1.5 T MR system.Results In four cases,all cerebellar dentate nuclei showed symmetric patchy hyper-intensity on T_2 weighted images and iso-intensity on diffusion-weighted images as well as hyper-intensity on ADC maps.The bilateral dorsum of the brain stem and thalamus were involved in one ease.Symmetric long T_1 and T_2 signals and high DWI signals with low ADC values in bilateral basal ganglia area were demonstrated in one case with severe symptoms.After treatment,repeated MR images in two cases showed the abnormal signals of dentate nucleus disappeared,and the lesions of basal ganglia area in one case tended to be cystie with longer T_1 and T_2 signals and low DWI signals.Conclusion It is specific for intoxication of sophorae subprostrate to affect the dentate nuclei and lentiform nuclei.MRI and DWI is helpful for the early diagnosis,differential diagnosis and prognosis evaluation of this disease.
