OBJECTIVETo explore the distribution of Chinese medicine (CM) syndrome types in primary liver cancer (PLC) and their differences of the survival time.

METHODSFrom May 2007 to March 2009, recruited were 151 PLC inpatients at Department of Tumor, Guangdong Provincial Hospital of Traditional Chinese Medicine. Their survival time were statistically calculated. Patients' average survival time and median survival time were calculated using Kaplan-Meier method. The Log-rank test was used to analyze their differences of survival time among different CM syndrome types.

RESULTSThe proportion of CM syndrome types in PLC patients were ranked from high to low as follows: mutual accumulation of dampness and blood stasis syndrome [MADBSS, 43.0% (65/151)], Gan-stagnation Pi-deficiency syndrome [GSPDS, 34.4% (52/151)], qi stagnation blood stasis syndrome [QSBSS, 9.3% (14/151)], retention of damp-heat syndrome [RDHS, 8.6%(13/151)], and Gan-Shen yin deficiency syndrome [GSYDS, 4.6% (7/ 151)]. The median survival time of different CM syndrome types were ranked from longer to shorter as follows: GSPDS (14.77 months), QSBSS (6.13 months), RDHS (5.27 months), MADBSS (4.78 months), and GSYDS (0.80 months). The mean survival times were ranked from longer to shorter as follows: GSPDS (12.40 months), QSBSS (8.84 months), MADBSS (6.99 months), RDHS (7.08 months), and GSYDS (0.72 months). There was statistical difference in the difference of the survival time among different CM syndrome types (P < 0.05).

CONCLUSIONSGSPDS and MADBSS were the most common CM syndrome types in PLC patients. There was difference in the survival time between GSPDS and MADBSS/between RDHS and GSYDS. There was difference in the survival time between MADBSS and GSYDS. Patients of GSPDS might get the best prognosis, while patients of GSYDS might get the poorest prognosis.

BACKGROUNDBivalirudin was widely used as an anticoagulant during coronary interventional procedure in western countries. However, it was not available in China before this clinical trial was designed. This randomized, single-blind and multicenter clinical trial aimed to evaluate the efficacy and the safety of domestic bivalirudin during percutaneous coronary intervention (PCI).

METHODSA randomized, single-blind, multicenter trial was designed. Elective PCI candidates in five centers were randomized into a bivalirudin group and a heparin group, which were treated with domestic bivalirudin and non-fractional heparin during the PCI procedure. The efficacy was evaluated by comparing the activated coagulation time (ACT), the procedural success rate (residual stenosis < 20% in target lesions without any coronary artery related adverse events within 24 hours after PCI), and the survival rate without major adverse cardiac events at 30 days after PCI between the two groups. Safety was evaluated by the major/minor bleeding rate.

RESULTSA total of 218 elective PCI patients were randomized into a bivalirudin group (n = 110) and heparin group (n = 108). Except for two patients needing additional dosing in the heparin group, the ACT values of all other patients in both groups were longer than 225 seconds at 5 minutes after the first intravenous bolus. Procedural success rates were respectively 100.0% and 98.2% in the bivalirudin group and heparin group (P > 0.05). Survival rates without major adverse cardiac events at 30 days after PCI were 100.0% in the bivalirudin group and 98.2% in the heparin group (P > 0.05). Mild bleeding rates were 0.9% and 6.9% (P < 0.05) at 24 hours, and 1.9% and 8.8% (P < 0.05) at 30 days after PCI in the bivalirudin group and heparin group respectively. There was one severe gastrointestinal bleeding case in the heparin group.

CONCLUSIONSDomestic bivalirudin is an effective and safe anticoagulant during elective PCI procedures. The efficacy is not inferior to heparin, but the safety is superior to heparin.

OBJECTIVES: To investigate the epidemiological characteristics of antisocial personality disorder (ASPD) in young men in Chengdu and explore the characteristics and risks of violence. METHODS: Stratified random sampling was used to conduct a self-assessment questionnaire survey in 4 108 males aged from 18 to 34 in Chengdu, including general demographic characteristics, structured clinical interview for the diagnostic and statistical manual of mental disorders-Ⅳ axis Ⅱ disorders (SCID-Ⅱ) personality disorder screen questionnaire, violence questionnaire, psychosis screening questionnaire (PSQ), Alcohol Use Disorders Identification Test (AUDIT) and drug use. χ² test, univariate and multivariate logistic regression were used for analysis and odds ratio (OR) was calculated. RESULTS: The positive rate of ASPD was 5.91%, which was associated with young age, unmarried, unemployment state, low educational level, violent behavior, psychotic symptoms, alcohol and drug use (P<0.05). Young men with ASPD also had a risk (P<0.05) of violence (OR was 8.51), multiple violence (OR was 16.57), injury (OR was 6.68), intentional violence (OR was 11.41), etc., the risk decreased after controlling for psychotic symptoms and substance abuse, but was still statistically significant. CONCLUSIONS The risk of violence, severe violence and intentional violence in young men in Chengdu is high, and psychotic symptoms and substance abuse increase the risk of ASPD violence and relate characteristics.

This study was designed to investigate the correlation between idiosyncratic liver injury and content of cis-2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside(cis-SG)in radix Polygoni multiflori Preparata(RPMP). In order to compare the effect of hepatotoxicity of different cis-SG contents in RPMP, rats were administered with 50% alcohol extracts of RPMP(7.56 g·kg^-1, via intragastric administration)alone or co-treated with lipopolysaccharide(LPS, 2.8 mg·kg^-1, via tail vein injection). The results showed that no significant alterations of plasma ALT and AST activities were observed in the normal rats. In the LPS treated rats, the group without light treatment and the group with 0.10% cis-SG after light treatment did not exhibit obvious injury in liver. The group with 0.35% cis-SG after light treatment and the group with 0.70% cis-SG after light treatment showed significant increases in ALT, AST, TNF-α, IL-6, NF-κB p65 and apoptosis rate(P < 0.05), causing pathological changes in the liver tissue. Through the content analysis of drug in patients with liver injury, we found that the content of cis-SG(> 0.40%)was generally higher than that of pieces collected from different origins(< 0.10%). The comparative analysis of experiments and clinical data showed that there was a relationship between the content of cis-SG and idiosyncratic liver injury. In order to reduce the risk of clinical medication, the content of cis-SG of 0.10% should be a limit of quality control in the production processing of Polygonum multiflorum.

About 15%-20% of drug-induced liver injury (DILI) will progress to chronic manifestation (CH-DILI), which sometimes advances rapidly to liver cirrhosis (LC-DILI) within 0.5-1 year with deteriorative clinical prognosis. Therefore, it is important to find a non-invasive diagnosis for early detection of liver cirrhosis. In this study, the metabolomic profiles revealed significant differences in the metabolites from the plasma of LC-DILI versus CH-DILI. We found 35 differential metabolites through principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA). Through pathway enrichment analysis, some up-regulated metabolic pathways reflected impaired liver functions such as bile acid, lipid synthesis and decomposition during cirrhosis. Five biomarkers were found to exhibit effective diagnosis value (AUC > 0.6), including phosphatidylcholine, lysoPC (18:1 (9Z)), creatine, taurochenodeoxycholic acid and taurocholic acid. Furthermore, we found that the relative content ratio between phosphatidylcholine and lysoPC (18:1 (9Z)) had a better distinguishing ability (AUC = 0.867). The relative content ratio also had the feature to reduce systematic errors of sample processing and instrument detection, therefore having a greater value for clinical application.

The objective of this work was to develop a bioassay to quantify the antiplatelet aggregation activity of hirudo for quality evaluation and control. Antithrombin activity of hirudo extracted by high temperature decoction was determined by thrombin titration. Antiplatelet aggregation activity of hirudo was determined through pharmacodynamic experiments in vitro and in vivo using a bioassay we developed for quantifying inhibition of platelet aggregation. Methodological investigation was carried out and the titers of 12 batches of hirudo samples were determined. During the experiment, the disposal of animals is in accordance with the ethical standards of animal experiments. The results showed that the antithrombin activity of hirudo decocted at high temperature decreased significantly and almost lost its activity. Hirudo inhibited platelet aggregation and results in vivo and in vitro were consistent. These assays were employed to test 12 batches of hirudo. The results demonstrated that the biopotency of 12 batches was 113.49, 96.13, 121.22, 127.33, 83.48, 108.72, 131.41, 127.95, 76.90, 126.27, 132.89 and 573.53 U·mg^-1. The method was reliable and reproducible and can be used to assess the quality of hirudo.

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.
