Objective To systematically evaluate the risk factors for postoperative delirium after surgery for Stanford type A aortic dissection. Methods We searched the CNKI, SinoMed, Wanfang data, VIP, PubMed, Web of Science, EMbase, The Cochrane Library database from inception to September 2022. Case-control studies, and cohort studies on risk factors for postoperative delirium after surgery for Stanford type A aortic dissection were collected to identify studies about the risk factors for postoperative delirium after surgery for Stanford type A aortic dissection. Quality of the included studies was evaluated by the Newcastle-Ottawa scale (NOS). The meta-analysis was performed by RevMan 5.3 software and Stata 15.0 software. Results A total of 21 studies were included involving 3385 patients. The NOS score was 7-8 points. The results of meta-analysis showed that age (MD=2.58, 95%CI 1.44 to 3.72, P＜0.000 01), male (OR=1.33, 95%CI 1.12 to 1.59, P=0.001), drinking history (OR=1.45, 95%CI 1.04 to 2.04, P=0.03), diabetes history (OR=1.44, 95%CI 1.12 to 1.85, P=0.005), preoperative leukocytes (MD=1.17, 95%CI 0.57 to 1.77), P=0.000 1), operation time (MD=21.82, 95%CI 5.84 to 37.80, P=0.007), deep hypothermic circulatory arrest (DHCA) time (MD=3.02, 95%CI 1.04 to 5.01, P=0.003), aortic occlusion time (MD=8.94, 95%CI 2.91 to 14.97, P=0.004), cardiopulmonary bypass time (MD=13.92, 95%CI 5.92 to 21.91, P=0.0006), ICU stay (MD=2.77, 95%CI 1.55 to 3.99, P＜0.000 01), hospital stay (MD=3.46, 95%CI 2.03 to 4.89, P＜0.0001), APACHEⅡ score (MD=2.76, 95%CI 1.59 to 3.93, P＜0.000 01), ventilation support time (MD=6.10, 95%CI 3.48 to 8.72, P＜0.000 01), hypoxemia (OR=2.32, 95%CI 1.40 to 3.82, P=0.001), the minimum postoperative oxygenation index (MD=−79.52, 95%CI −125.80 to −33.24, P=0.000 8), blood oxygen saturation (MD=−3.50, 95%CI −4.49 to −2.51, P＜0.000 01), postoperative hemoglobin (MD=−6.35, 95%CI −9.21 to −3.50, P＜0.000 1), postoperative blood lactate (MD=0.45, 95%CI 0.15 to 0.75, P=0.004), postoperative electrolyte abnormalities (OR=5.94, 95%CI 3.50 to 10.09, P＜0.000 01), acute kidney injury (OR=1.92, 95%CI 1.34 to 2.75, P=0.000 4) and postoperative body temperature (MD=0.79, 95%CI 0.69 to 0.88, P＜0.000 01) were associated with postoperative delirium after surgery for Stanford type A aortic dissection. Conclusion The current evidence shows that age, male, drinking history, diabetes history, operation time, DHCA time, aortic occlusion time, cardiopulmonary bypass time, ICU stay, hospital stay, APACHEⅡ score, ventilation support time, hypoxemia and postoperative body temperature are risk factors for the postoperative delirium after surgery for Stanford type A aortic dissection. Oxygenation index, oxygen saturation, and hemoglobin number are protective factors for delirium after Stanford type A aortic dissection.

The paper introduces professor ZHUANG Li-xing's clinical experience in treatment of dyskinesia of Parkinson's disease with acupuncture at triple-acupoint prescription. In pathogenesis, dyskinesia of Parkinson's disease refers to yang deficiency and disturbing wind. In treatment, acupuncture focuses on warming yang, promoting the circulation of the governor vessel, regulating the spirit and stopping trembling; and Baihui (GV 20), Suliao (GV 25) and Dingchanxue (Extra) are selected to be "trembling relief needling". In combination with Jin's three needling, named "three-trembling needling" "three-governor-vessel needling" and "three-spasm needling", the triple-acupoint prescription is composed. To ensure the favorable therapeutic effect, this prescription is modified according to the symptoms and the specific techniques of acupuncture are combined such as conducting qi, harmonizing yin and yang, and manipulating gently for reinforcing and reducing.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective:To explore the distribution characteristics of memory B cells and its relationship with bone erosion in patients with rheumatoid arthritis (RA), and to further understand the mechanism of B cells in the pathogenesis of RA.Methods:B cell subsets in peripheral blood of 200 RA patients and 50 healthy individuals were detected by flow cytometry. According to the surface markers CD19, CD27 and lgD, B cells were divided into CD19 +CD27 +lgD - switched memory B cells, CD19 +CD27 +lgD + non-switched memory B cells, CD19 +CD27 -lgD - double-negative memory B cells and CD19 +CD27 -lgD + naive B cells. B cells in RA patients with various disease activity score, course of disease and treatment were analyzed. Patients were divided into four groups according to the results of joint ultrasonography, including patients without bone erosion, patients with hand bone erosion, patients with knee bone erosion and patients with hand and knee bone erosion. The relationship between the distribution of B cell subsets, autoantibodies and RA bone erosion were analyzed. Differences between the groups were analyzed by independent-samples t test, Mann-Whitney U test and χ2 test. The analysis of variance, Kruskal-Wallis analysis were used for multi-group comparison, Spearman correlation analysis was also used for correlation analysis. Results:①RA patients showed significantly decreased non-switched memory B cells [(9.5±6.7)% vs (12.1±4.7)%, t=2.46, P=0.015] and increased double negative memory B cells [(3.8±2.5)% vs(2.7±1.3)%, t=-4.74, P<0.001] in comparison to healthy individuals. The percentage of non-switched memory B cells were decreased in RA patients with moderate disease activity [(8.4±4.7 )% vs (12.4±7.5)%, t=3.13, P=0.001] and high disease activity [(7.8±7.6)% vs (12.4±7.5)%, t=3.00, P=0.003] in comparison to those in RA patients who achieved remission. Meanwhile, the na?ve B cells [(70.3±15.0)% vs (63.9±14.6)%, t=-2.15, P=0.034] were increased in RA patients with moderate disease activity. No difference was found in RA patients with different disease courses. Total B cells [(4.8±2.9)% vs (7.2±4.1)%, t=-3.24, P=0.001], non-switched memory B cells (7.6±4.3)% vs (10.0±7.1)%, t=-2.63, P=0.010) in RA patients who received prednisone treatment were decreased, while double-negative memory B cells (4.9±3.0)% vs (3.6±2.3)%, t=-2.79, P=0.006] were increased compared with those in RA patients without prednisone treatment. Non-switched memory B cells was decreased in RA patients with hand and knee erosion compared with RA patients without erosion [6.8%(2.5%, 9.5%) vs 9.7%(5.5%, 17.5%), Z=-2.12, P=0.034]. Double negative memory B cells in subgroup with keen erosion [3.3%(2.7%, 5.0%) vs 2.6%(1.9%, 3.8%), Z=-2.09, P=0.036]as well as with hand and knee erosion [3.9%(2.3%, 5.6%) vs 2.6%(1.9%, 3.8%), Z=-2.41, P=0.016] were higher than those in patients without erosion. In addition, higher serum RF level was found in subgroup RA patients with hand and knee erosion compared with subgroup of RA patients without erosion [141.0 (38.0, 874.0) U/ml vs 53.5 (10.0, 106.0)U/ml, Z=-2.07, P=0.039]. Meanwhile, the positive rate of ACPA in RA patients with bone erosion of hand was significantly higher than that of RA patients without bone erosion [81%(52/64) vs 64%(38/59), χ2=4.44, P=0.043). Conclusions:The results suggest that the increase of double negative memory B cells, the decrease of non-switched memory B cells and higher level of autoantibodies may closely relate to bone erosion of RA, which may be one of the pathogenesis of disability in RA.

Objective: To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with programmed death-1 (PD-1) antibody in operable, borderline or potentially resectable locally advanced esophageal squamous cell carcinoma(ESCC) in the real world. Methods: The study retrospectively analyzed 28 patients with operable or potentially resectable locally advanced ESCC patients treated with preoperative chemotherapy combined with PD-1 inhibitor in Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from April 2020 to March 2021. According to the clinical TNM staging system of the 8th edition of the American Joint Committee on Cancer, there were 1, 15, 10, 1 and 1 case of stage Ⅱ, Ⅲ, ⅣA, ⅣB and unknown stage respectively. The treatment was two cycle of dual drug chemotherapy regimen including taxane plus platinum or fluorouracil combined with PD-1 antibody followed by tumor response assessment and surgery if the patient was eligible for resection. Results: Of the 28 patients, 1, 2, 3 and 4 cycles of chemotherapy combined with PD-1 antibody treatment completed in 1, 21, 5, and 1 patient, respectively. Objective response rate (ORR) was 71.4% (20/28), and disease control rate (DCR) was 100% (28/28). The incidence of adverse events exceeding grade 3 levels was 21.4% (6/28), including 3 neutropenia, 1 leukopenia, 1 thrombocytopenia and 1 immune hepatitis. There was no treatment-related death. Of the 23 patients underwent surgery, R0 resection rate was 87.0% (20/23), 13 patients had down staged to the T1-2N0M0 I stage, the pCR rate was 17.3% (4/23), and the pCR rate of primary tumor was 21.7% (5/23). Four patients received definitive chemoradiotherapy. One patient rejected surgery and other treatment after achieved PR response. Conclusion: Neoadjuvant chemotherapy combined PD-1 inhibitor is safe and has high efficacy in operable, borderline or potentially resectable locally advanced ESCC, and it is a promising regimen.

To explore the changes and the reaction mechanisms between soil microecological environment and the content of secon-dary metabolites of plants under water deficit, this study carried out a pot experiment on the 3-leaf stage seedlings of Rheum officinale to analyze their response mechanism under different drought gradients(normal water supply, mild, moderate, and severe drought). The results indicated that the content of flavonoids, phenols, terpenoids, and alkaloids in the root of R. officinale varied greatly under drought stresses. Under mild drought stress, the content of substances mentioned above was comparatively high, and the content of rutin, emodin, gallic acid, and(+)-catechin hydrate in the root significantly increased. The content of rutin, emodin, and gallic acid under severe drought stress was significantly lower than that under normal water supply. The number of species, Shannon diversity index, richness index, and Simpson index of bacteria in the rhizosphere soil were significantly higher than those in blank soil, and the number of microbial species and richness index decreased significantly with the aggravation of drought stresses. In the context of water deficit, Cyanophyta, Firmicutes, Actinobacteria, Chloroflexi, Gemmatimonadetes, Streptomyces, and Actinomyces were the dominant bacteria in the rhizosphere of R. officinale. The relative content of rutin and emodin in the root of R. officinale was positively correlated with the relative abundance of Cyanophyta and Firmicutes, and the relative content of(+)-catechin hydrate and(-)-epicatechin gallate was positively correlated with the relative abundance of Bacteroidetes and Firmicutes. In conclusion, appropriate drought stress can increase the content of secondary metabolites of R. officinale from physiological induction and the increase in the association with beneficial microbe.

Objective:To analyze the clinical characteristics of asymptomatic infection of brucellosis, in order to provide reference for prevention and treatment of brucellosis.Methods:Retrospective analysis was used to collect the clinical data of patients with brucellosis asymptomatic infection and confirmed cases admitted to the 940th Hospital of Joint Logistics Support Force of Chinese PLA from 2017 to 2021, and the demography characteristics, clinical manifestations and laboratory test results were analyzed.Results:The results showed that a total of 18 cases of asymptomatic infection and 85 confirmed cases of brucellosis were included, and there was no statistically significant difference in age, gender, occupation and ethnicity distribution between the two groups ( F = 7.09, χ 2 = 0.74, 4.02, 0.55, P = 0.295, 0.785, 0.327, 1.000). The 18 cases of asymptomatic infection of brucellosis were found through screening in key populations, and no clinical symptoms or abnormal imaging signs were observed. The clinical symptoms of 85 confirmed cases were mainly muscle and joint pain, fever, sweating, fatigue, and low back pain; and the imaging manifestations were mainly arthritis, splenomegaly, and spondylitis. The median percentage of eosinophils (0.70%, 1.40%), percentage of basophils (3.05%, 0.40%), C-reactive protein (1.62, 4.62 mg/L), erythrocyte sedimentation rate (1.00, 11.00 mm/h), and antibody titer of serum agglutination test (1 ∶ 100, 1 ∶ 200) showed statistically significant differences between asymptomatic infection and confirmed cases of brucellosis ( Z = - 2.97, - 5.11, - 3.49, - 3.21, - 3.50, P = 0.003, 0.001, 0.001, 0.001, 0.007). Conclusions:There is a difference in the composition of granulocytes between asymptomatic infection and confirmed cases of brucellosis, and the level of inflammatory response indicators is lower than that of confirmed cases. Regular seroepidemiological surveys among key populations can help screen for asymptomatic infection of brucellosis.

OBJECTIVES: To explore the influencing factors of the horizontal distance of bodies in the high falling scene and the feasibility of inferring the falling mode based on it. METHODS: A total of 614 high falling deaths and 15 cases of corpse dumping from high altitudes were collected. The relationship between the horizontal distance and the falling height, as well as the sex, age and manner of death (suicide, accident and corpse dumping) were observed. RESULTS: The horizontal distance increased with the increase of falling height, and the difference among the height groups was statistically significant. The horizontal distance decreased with the increase of the age of the deceased, in each height group, the difference between the group over 60 years old and other age groups was statistically significant (P<0.05). The horizontal distance of male deceased was (1.99±0.27) m, which was greater than that of female deceased (1.88±0.19) m, and the difference was statistically significant in partial height groups (P<0.05). Roof falls had a greater horizontal movement distance than window falls. Except for the >20-30 m group, there was no significant difference in horizontal distance between suicide high falls and accidental high falls in other height groups. CONCLUSIONS The horizontal distance is affected by the falling height, the sex and age of the victim, and the spatial characteristics of the falling starting point.
