Objective To study the influencing factors of overall survival(OS)and cancer-specific survival(CSS)in patients with hepatocellular carcinoma and pulmonary metastasis and establish nomograms to predict survival.Methods The study pop-ulation consisted of 2242 cases with a first primary hepatocellular carcinoma who presented with pulmonary metastasis at the time of diagnosis in the Surveillance,Epidemiology,and End Results(SEER)database of the National Cancer Institute from 2010 to 2016.The influencing factors of OS and CSS were evaluated by using multivariable Cox proportional hazards regression mod-els.Nomograms predicting 1-year OS and CSS were constructed.Data analysis and construction of nomograms were performed with Cox proportional hazards regression models,the Kaplan-Meier curves(log-rank test)and C-index.Results The 1-year OS and CSS rates in the cohort were 10.5％(95％CI:8.7％-12.7％)and 11.8％(95％CI:9.8％-14.2％),respectively.In multi-variable survival analysis,insurance status,small tumor,tumor stage 1-2,negative AFP,chemotherapy treatment,and surgical treatment were associated with OS.Sex,insurance status,tumor staging,AFP status,chemotherapy and surgery treatment were incorporated into the nomogram for CSS prediction.The bootstrap-corrected concordance indexes(C-indexes)predicted by nomo-gram were 0.72(95％CI:0.70-0.74)and 0.71(95％CI:0.69-0.73),which could be used to predict OS and CSS.The models were internally validated and shown to have good calibration.Conclusion The nomograms are established based on the associat-ed factors,which shows good performance in predicting survival in patients with hepatocellular carcinoma and pulmonary metas-tasis.

Objective:To summarize the clinical characteristics, prognostic factors and treatment outcomes of childhood aggressive mature B-cell lymphoma after liver transplantation.Methods:This retrospective study included 18 children with newly diagnosed aggressive mature B-cell lymphoma after liver transplantation and treated from June 2018 to June 2022 in the Department of Hematology and Oncology of Shanghai Children′s Medical Center, Shanghai Jiao Tong University School of Medicine. Clinical characteristics, treatment and outcomes of patients at last evaluation were analyzed. Overall survival (OS) and event free survival (EFS) rates were calculated by Kaplan-Meier method and Log-Rank analysis was performed to find factors of poor prognosis.Results:Among all 18 patients, there were 6 males and 12 females, and the age of onset was 40 (35, 54) months. The interval from transplant to tumor diagnosis was 21 (17, 35) months and 5 patients had early onset disease (<1 year since transplant). Seventeen patients had abdominal lesions. Diarrhea, vomiting and abdominal masses were the main clinical manifestations. All patients were Epstein-Barr virus (EBV) related posttransplant lymphoproliferative disorders (PTLD). One patient received individualized therapy due to critical sick at diagnosis, and the remaining 17 patients received CP (cyclophosphamide, methylprednisolone plus rituximab) and (or) modified EPOCH (prednisone, etoposide, doxorubicin, vincristine, cyclophosphamide plus rituximab) regimens. Of all 18 patients, 15 cases got complete response, 2 cases got partial response, 1 patient died of severe infection. The 2-year OS and EFS rates of 18 patients were (94±5)% and (83±8)%, respectively. None of age, gender or early onset disease had effect on OS and EFS rates in univariate analysis (all P>0.05). Conclusions:The symptoms of PTLD were atypical. Close surveillance of EBV-DNA for patients after liver transplantation was crucial to early stage PTLD diagnosis. CP or modified EPOCH regimen was efficient for pediatric patients with aggressive mature B cell lymphoma after liver transplantation.

Objective To investigated the effect of stenosis characteristics (vascular elasticity and plaque properties) on myocardial ischemia. Methods An ideal geometric multi-scale coronary stenosis model based on fluid-structure interaction was established, and the fractional flow reserve (FFR) was simulated to evaluate myocardial ischemia. The effects of vascular elastic wall (elastic modulus of 1 MPa) and rigid wall, plaque types (lipid-rich plaque and calcified plaque) and plaque volume on myocardial ischemia were considered separately. Results The FFRCT simulation result of vessels with elastic wall was larger than that with rigid wall under all stenosis situations. The FFRCT of vessels in lipid-rich lesions was higher than that of calcified plaque (P=0.001). The trapezoidal plaque volume was larger than the cosine plaque volume, and the FFRCT of vessels in trapezoidal plaque was smaller than that of cosine plaque (P=0.001). Conclusions Vascular elasticity is a critical factor to simulate vascular hemodynamics. In moderate stenosis, calcified plaques are more likely to induce myocardial ischemia due to the larger luminal deformation and dilation of rich lipid plaque. When the stenosis is constant, the smaller the plaque volume, the higher the FFRCT and the smaller the possibility of myocardial ischemia.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective:To observe the effects of berberine on procoagulant and fibrinolytic inhibitory factors produced by rat type Ⅱ alveolar epithelial cell (AECⅡ) induced by lipopolysaccharide (LPS).Methods:AECⅡ cells (RLE-6TN cells) were cultured in vitro, and the cells in logarithmic growth phase were collected. The cytotoxicity text of berberine was detected by cell counting kit-8 (CCK-8) to determine the drug concentration range according to inhibition concentration of half cells (IC 50). The RLE-6TN cells were divided into five groups, the cells in blank control group were cultured in DMEM; the cells in LPS group were stimulated with 5 mg/L LPS; and the cells in berberine pretreatment groups were pretreated with 20, 50 and 80 μmol/L berberine for 1 hour, and then were co-cultured with 5 mg/L LPS. The cells were collected after LPS induced for 24 hours. The protein and mRNA expression levels of tissue factor (TF), tissue factor pathway inhibitor (TFPI) and plasminogen activator inhibitor-1 (PAI-1) in the cells were detected by Western blotting and real-time fluorescence quantification reverse transcription-polymerase chain reaction (RT-qPCR). The levels of activated protein C (APC), precollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT) and antithrombin Ⅲ (ATⅢ) in the cell supernatant were measured by enzyme linked immunosorbent assay (ELISA). Results:According to the inhibition rate curve, the IC 50 of berberine on RLE-6TN cells was 81.16 μmol/L. Therefore, 20, 50 and 80 μmol/L were selected as the intervention concentration of berberine. Compared with the blank control group, the expression and secretion of procoagulant and fibrinolytic inhibitory factors were abnormal in RLE-6TN cells after LPS induced for 24 hours. The protein and mRNA expression levels of TF and PAI-1 in the LPS group were significantly increased, but the protein and mRNA expression levels of TFPI were significantly decreased. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly decreased, while the levels of PⅢP and TAT were significantly increased. After pretreatment with berberine, the abnormal expression and secretion of procoagulant and fibrinolytic inhibitory factors induced by LPS were corrected in a dose-dependent manner, especially in 80 μmol/L. Compared with the LPS group, the protein and mRNA expression levels of TF and PAI-1 in the berberine 80 μmol/L group were significantly decreased [TF protein (TF/GAPDH): 0.45±0.02 vs. 0.55±0.03, TF mRNA (2 -ΔΔCt): 0.39±0.08 vs. 1.48±0.11, PAI-1 protein (PAI-1/GAPDH): 0.37±0.02 vs. 0.64±0.04, PAI-1 mRNA (2 -ΔΔCt): 1.14±0.29 vs. 4.18±0.44, all P < 0.01] and those of TFPI were significantly increased [TFPI protein (TFPI/GAPDH): 0.53±0.02 vs. 0.45±0.02, TFPI mRNA (2 -ΔΔCt): 0.94±0.08 vs. 0.40±0.05, both P < 0.01]. Meanwhile, the levels of APC and ATⅢ in the cell supernatant were significantly increased [APC (μg/L): 1 358.5±26.0 vs. 994.2±23.1, ATⅢ (μg/L): 118.0±7.4 vs. 84.4±2.7, both P < 0.01], while those of PⅢP and TAT were significantly decreased [PⅢP (μg/L): 11.2±0.4 vs. 18.6±0.9, TAT (ng/L): 222.1±2.8 vs. 287.6±7.0, both P < 0.01]. Conclusions:Berberine could inhibit the LPS-induced expressions of procoagulant and fibrinolytic inhibitory factors in rat AECⅡ cells and promote the expressions of anticoagulant factors in a dose-dependent manner. Berberine may be a new therapeutic target for alveolar hypercoagulability and fibrinolysis inhibition in acute respiratory distress syndrome (ARDS).

Objective:To determine the effect of andrographolide (AD) on the expression of procoagulant and fibrinolytic inhibitory factors in rat type Ⅱ alveolar epithelial cells (AECⅡ) stimulated by lipopolysaccharide (LPS).Methods:The AECⅡ cells RLE-6TN in the logarithmic growth phase were divided into 5 groups: the normal control (NC) group, the LPS group, and the 6.25, 12.5, and 25 mg/L AD groups (AD 6.25 group, AD 12.5 group, AD 25 group). The NC group was cultured with RPMI 1640 conventional medium. In the LPS group, 5 mg/L LPS was added to the RPMI 1640 conventional medium for stimulation. Cells in the AD groups were treated with 6.25, 12.5, and 25 mg/L AD in advance for 1 hour and then given LPS to stimulate the culture. The cells and cell culture supernatant were collected 24 hours after LPS stimulation. The protein and mRNA expressions of tissue factor (TF), tissue factor pathway inhibitor (TFPI), and plasminogen activator inhibition-1 (PAI-1) in cells were detected by Western blotting and real-time fluorescent quantitative polymerase chain reaction (RT-qPCR). The levels of procollagen Ⅲ peptide (PⅢP), thrombin-antithrombin complex (TAT), antithrombin Ⅲ (AT-Ⅲ) and activated protein C (APC) in the cell supernatant were detected by enzyme linked immunosorbent assay (ELISA).Results:Compared with the NC group, the protein and mRNA expressions of TF and PAI-1 in the LPS group were significantly increased, and the protein and mRNA expressions of TFPI were significantly reduced. At the same time, the levels of PⅢP and TAT in the cell supernatant were significantly increased, the levels of AT-Ⅲ, APC were significantly reduced. Compared with the LPS group, the protein and mRNA expressions of TF and PAI-1 in AD 6.25 group, AD 12.5 group, AD 25 group were significantly reduced [TF/GAPDH: 0.86±0.08, 0.45±0.04, 0.44±0.04 vs. 1.32±0.10, TF mRNA (2 -ΔΔCt): 2.59±0.25, 2.27±0.05, 1.95±0.04 vs. 4.60±0.26, PAI-1/GAPDH: 2.11±0.07, 1.45±0.04, 0.86±0.09 vs. 2.56±0.09, PAI-1 mRNA (2 -ΔΔCt): 3.50±0.22, 2.23±0.29, 1.84±0.09 vs. 6.60±0.27, all P < 0.05], while the protein and mRNA expressions of TFPI were significantly increased [TFPI/GAPDH: 0.78±0.05, 0.81±0.03, 0.84±0.07 vs. 0.36±0.02, TFPI mRNA (2 -ΔΔCt): 0.46±0.09, 0.69±0.07, 0.91±0.08 vs. 0.44±0.06, all P < 0.05]. Also the levels of PⅢP and TAT in the cell supernatant were significantly reduced, and the levels of AT-Ⅲ and APC were significantly increased [PⅢP (μg/L): 13.59±0.23, 12.66±0.23, 10.59±0.30 vs. 15.82±0.29, TAT (ng/L): 211.57±6.41, 205.69±4.04, 200.56±9.85 vs. 288.67±9.84, AT-Ⅲ (μg/L): 102.95±3.86, 123.92±2.63, 128.67±1.67 vs. 92.93±3.36, APC (μg/L): 1 188.95±14.99, 1 366.12±39.93, 1 451.15±29.69 vs. 1 145.55±21.07, all P < 0.05]. With the increase of the dose of AD, the above-mentioned promotion and inhibition effects became more obvious. In the AD 25 group, TF, PAI-1 protein and mRNA expressions decreased, TFPI mRNA expression increased, PⅢP level in the supernatant decreased and AT-Ⅲ, APC levels increased compared with AD 6.25 group, the difference was statistically significant, and the decrease of PAI-1 protein expression and PⅢP level in the supernatant were also statistically significant compared with AD 12.5 group. Conclusions:Andrographolide in the dose range of 6.25-25 mg/L can dose-dependently inhibit the expression and secretion of procoagulant and fibrinolytic inhibitor-related factors in AECⅡ cells RLE-6TN stimulated by LPS, and promote the secretion of anticoagulant factors. 25 mg/L has the most obvious effect.

Objective:To explore the efficacy and safety of low- and medium-dose of glucocorticoids in adult patients with acute respiratory distress syndrome (ARDS) through Meta-analysis and trials sequential analysis (TSA).Methods:Databases associated with adult ARDS treatment with low- and medium-dose glucocorticoids both in English and in Chinese were searched from PubMed, Medline, China Biology Medicine (CBM), Cochrane Library, CNKI, Wanfang Data and VIP, of which the search duration was from the establishment of the database to December 2020. Low-dose glucocorticoids were defined as methylprednisolone ≤ 1 mg·kg -1·d -1, and medium dose glucocorticoids were defined as methylprednisolone ≤ 2 mg·kg -1·d -1. According to the Cochrane Collaboration bias risk assessment tool, the quality of the included literature was evaluated, and the data were extracted. Meta-analysis and TSA were used to evaluate the effects of low- and medium-dose glucocorticoids on the hospital mortality, intensive care unit (ICU) mortality, and mechanical ventilation free time in ICU for 28 days, PaO 2/FiO 2, and the occurrence of nosocomial infections and hyperglycemia. Results:A total of 996 patients in 7 literatures were finally included, including 515 patients in the low- and medium-dose glucocorticoid group (hormone group) and 481 patients in the conventional treatment group (control group). The research quality of 7 literatures was relatively high. The results of Meta-analysis and TSA showed that, compared with the control group, the hospital mortality in the hormone group was significantly decreased [relative risk ( RR) = 0.77, 95% confidence interval (95% CI) was 0.66-0.89, P = 0.000 6], and mechanical ventilation free time in ICU for 28 days was significantly prolonged [standardized mean difference ( SMD) = 0.50, 95% CI was 0.36-0.65, P < 0.000 1]. Although Meta-analysis showed that the ICU mortality of the hormone group was significantly lower than that of the control group ( RR = 0.61, 95% CI was 0.38-0.99, P = 0.04), the TSA results showed that the cumulative Z value crossed the traditional threshold, but did not cross the TSA cut-off value, and the sample size did not reach required information size (RIS, n = 3 252), needed more research to confirm. Although Meta-analysis showed that PaO 2/FiO 2 in the hormone group was significantly higher than that in the control group ( SMD = 0.78, 95% CI was 0.13-1.43, P = 0.02), TSA showed that the cumulative Z value did not pass the traditional and TSA cut-off values. More research was needed for verification. Meta-analysis also showed that there was no significant difference in the incidence of new infection ( RR = 0.93, 95% CI was 0.74-1.17, P = 0.54) and the incidence of hyperglycemia ( RR = 1.11, 95% CI was 1.00-1.23, P = 0.05) between the hormone group and the control group. Conclusion:low- and medium-dose of glucocorticoids therapy can reduce the hospital mortality of adult ARDS patients and shorten the mechanical ventilation duration in ICU for 28 days, and low- and medium-dose of glucocorticoids therapy does not increase the risk of infection and hyperglycemia.

Objective: Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear. Methods: A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( Results: Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks. Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

Objective:To explore the effect of small dose of low molecular weight heparin on the prognosis of elderly patients with severe pneumonia using systematic evaluation method.Methods:Databases including Wanfang data, VIP, CNKI, SinoMed, PubMed, Embase and Cochrane Library were searched for randomized controlled trial (RCT) studies about the comparison of conventional therapy and low molecular weight heparin on prognosis of elderly patients with severe pneumonia from the time of database establishment to August 2019. The patients in conventional treatment group were treated by improving ventilation, anti-infection, eliminating phlegm, relieving asthma and maintaining homeostasis while those in low molecular weight heparin group were subcutaneously injected with low molecular weight heparin of 4 000 U, once a day for 7 days. The patients' main outcomes included the oxygenation index (PaO 2/FiO 2) after 7 days of treatment, duration of mechanical ventilation, mortality in hospital, and secondary outcomes included acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score and coagulation function after 7 days of treatment, the length of intensive care unit (ICU) stay, and incidence of bleeding. Data extraction and quality evaluation were conducted. The Meta-analysis of included studies that met the quality standards was performed using RevMan 5.3 software. Funnel diagram analysis was used to analyze the parameters with no less than 10 studies enrolled. Results:A total of 14 RCT studies were enrolled involving 1 173 elderly patients with severe pneumonia, among whom 590 received low molecular weight heparin while the other 583 received conventional therapy. All the included studies were well designed and of high quality. The results of Meta-analysis showed that compared with conventional therapy, small dose of low molecular weight heparin significantly elevated PaO 2/FiO 2 after 7 days of treatment [mean difference ( MD) = 19.25, 95% confidence interval (95% CI) was 16.88 to 21.61, P < 0.000 01], shortened the duration of mechanical ventilation ( MD = -48.88, 95% CI was -67.42 to -30.33, P < 0.000 01), and decreased mortality in hospital [odds ratio ( OR) = 0.40, 95% CI was 0.22 to 0.73, P = 0.003] and APACHEⅡ score after 7 days of treatment ( MD = -3.38, 95% CI was -3.94 to -2.83, P < 0.000 01), and shortened the length of ICU stay ( MD = -4.51, 95% CI was -5.75 to -3.27, P < 0.000 01). There was no significant difference in the changes of coagulation parameters after 7 days of treatment or the incidence of bleeding between low molecular weight heparin group and conventional therapy group [7-day thrombin time (TT): MD = 0.57, 95% CI was -0.15 to 1.28, P = 0.12; 7-day prothrombin time (PT): MD = 0.32, 95% CI was -0.35 to 0.98, P = 0.35; 7-day fibrinogen (FIB): MD = -0.17, 95% CI was -0.45 to 0.10, P = 0.22; incidence of bleeding: OR = 0.86, 95% CI was 0.36 to 2.07, P = 0.74]. The funnel diagram showed that there was publication bias of included 10 studies about APACHEⅡ score after 7 days of treatment. Conclusion:Small dose of low molecular weight heparin can improve the prognosis of elderly patients with severe pneumonia and it has no obvious side-effect on coagulation function.
