Objective To investigate the biological role of LINC01614 in non-small cell lung cancer A549 cells and its drug resistance-related mechanism. Methods The CRISPR/Cas9 technology was used to construct the A549 cell model with knockdown of LINC01614. Transcriptome sequencing was performed on A549 cells knocked down with LINC01614. We validated the transcriptomic differential genes MCAM and ABCC3 at the gene level and MCAM at the protein level, detected the IC₅₀ changes of A549 cells after knockdown of LINC01614 under the effect of different concentrations of cisplatin, and detected the effect of knockdown of LINC01614 on the migration ability of A549 cells. Results Of the 2 713 DEGs after knockdown of LINC01614, a total of 1 626 genes were up-regulated and 1, 087 genes were down-regulated. GO analysis showed that DEGs were associated with intracellular signaling, cell adhesion, and so on. Meanwhile, the KEGG analysis showed that DEGs were associated with the Wnt signaling pathway, TGF-β signaling pathway, and Rap1 signaling pathway. Selection of drug resistance-associated gene ABCC3 from DEGs for validation with MCAM: qRT-PCR results showed that knockdown of LINC01614 significantly down-regulated the expression of MCAM (P<0.05) and upregulated the expression of ABCC3 on A549 cells (P<0.05). After knockdown of LINC01614, the protein expression of MCAM, was significantly decreased in A549 cells (P<0.05); the IC₅₀ of A549 cells to cisplatin was significantly increased (P<0.05); and the scratch healing rate of A549 cells was also significantly decreased (P<0.05). Conclusion LINC01614 may be associated with the proliferation, invasion, and apoptotic pathways of A549 cells. In addition, LINC01614 may exert its migration ability through MCAM and chemoresistance to cisplatin through ABCC3.

ObjectiveTo explore and establish the liver injury risk prediction model of indirect toxicity of Chinese medicinals under the condition of compound formulas， and provide new ideas and methods for the study of evaluation of liver injury of Chinese medicinals based on indirect toxicity. MethodsTaking Buguzhi （Fructus Psoraleae） pre-parations as model drug， the combined Chinese medicinals with Buguzhi （Fructus Psoraleae） of high frequency are screened out， and their components and action targets were obtained through TCMSP， TCMIP and PharmMapper databases. The association strength value and risk value of Chinese medicinals that acted on the nuclear factor κB （NF-κB） pathway were analyzed. For those having greater values than the median association strength value and risk value were regarded as indirect Chinese medicinals of liver injury risk. In this way， a prediction model of liver injury risk of Chinese medicinals was constructed based on immune activation-related indirect liver injury process （taking NF-κB pathway as an example）. And verification of the prediction model was performed using Heshouwu （Radix Polygoni Multiflori） preparations. ResultsThe prediction model of liver injury risk based on important immunoactivated pathway （taking NF-κB pathway as an example） found that Yinyanghuo （Herba Epimedii） （association strength value = 0.18， risk value = 0.25） was a Chinese medicinal with potential risk of indirect liver injury within Buguzhi （Fructus Psoraleae） prepartions， which may increase the risk of liver injury by positively regulating Bruton's tyrosine kinase （Btk） and protein kinase C theta （PKCθ） on NF-κB pathway. Further verification of prediction model by Heshouwu （Radix Polygoni Multiflori） preparations showed that Buguzhi （Fructus Psoraleae） （association strength value = 0.25， risk value = 0.33） and Tusizi （Semen Cuscutae） （Semen Cuscutae， association strength value = 0.34， risk value = 0.33） may increase the liver injury risk of Heshouzu. ConclusionThe liver injury risk prediction model of indirect toxicity of Chinese medicinals has been constructed in this study， providing metho-dological reference for the identification of Chinese medicinals of indirect liver injury risk under the condition of compound formulas.

Objective: Although some studies have linked Asari Radix et Rhizoma (Asari Radix) administration to hepatocellular carcinoma (HCC), few studies have examined the association between the development of HCC and use of Asari Radix among patients in mainland China. This study aimed to evaluate the real-world association between Asari Radix and HCC in patients to strengthen the understanding of Asari Radix safety. Methods: A retrospective cohort study among hepatitis B virus (HBV)-monoinfected patients and non-HBV-monoinfected patients were performed. Patients over 18 years of age were eligible for inclusion. Prescription records of inpatients and outpatients were inquired to distinguish Asari Radix users and nonusers. The risk of developing HCC among Asari Radix users and nonusers in the HBV cohort and the non-HBV cohort was analyzed. Results: There were 49 500 HBV and 133 148 non-HBV patients involved in the two cohorts. Among HBV patients (2 901 users; 46 599 nonusers), the prevalence of HCC in Asari Radix users was lower than that in nonusers (145.70 vs. 265.43 per 10

Objective To investigate the potential medication risk by identifying and analyzing the features of liver-related adverse drug reaction (ADR) in pregnant women. Methods A retrospective study was performed for the reports on liver-related ADR in pregnant women from January 1, 2012 to December 31, 2016 in HILI Cloud (hilicloud.net). Main clinical features and medication rules were analyzed, and reporting odds ratio ( ROR ) was used to analyze the relative risk of related drugs. Results Methotrexate, mifepristone, and ritodrine were the high-frequency drugs reported for liver-related ADR in pregnant women and were mainly used for termination of ectopic pregnancy and treatment of hydatidiform mole. The relative risk analysis of liver-related ADR showed that in pregnant women, the use of methotrexate ( ROR =37.52, 95% confidence interval [ CI ]=31.35-44.89), progesterone ( ROR =7.33, 95% CI : 2.75-19.59), and dydrogesterone ( ROR =6.58, 95% CI : 2.20-19.69) was strongly associated with the risk of liver injury, and the association of methotrexate with the risk of liver injury in pregnant women was significantly stronger than that in non-pregnant women ( ROR =1.71, 95% CI : 1.47-4.36). Conclusion The potential risk of liver injury should be taken seriously in pregnant women using the drugs such as methotrexate and progesterone, so as to avoid serious adverse reactions.

Objective To establish the intelligent identification method for the big data of liver injury-related adverse drug reaction (ADR) based on the construction of text database. Methods With the keywords including "drug-induced liver injury" and "abnormal liver function" and a search time of January 1, 2012 to December 31, 2016, 5% (4152 cases) of the case reports of liver injury-related ADR were retrieved and extracted from the China Adverse Drug Reaction Monitoring System, and then based on clinical reevaluation by physicians, these cases were classified into "negative cases", "suspected cases", and "confirmed cases". On this basis, key elements (including ADR name, biochemical parameter, and clinical symptoms) were identified. An intelligent identification method for liver injury-related ADR was established based on the correlation analysis between key elements and clinical reevaluation and the receiver operating characteristic (ROC) curve for determining cut-off values, and the method of cross validation was used to evaluate the performance of this intelligent identification method. Results The formula for the evaluation and identification of liver injury-related ADR was as follows: total score (M)=symptom score+index score+ADR name score. This formula showed the best discriminatory ability to distinguish "negative case" from "suspected case" or "confirmed case" at M=5 (area under the ROC curve [AUC]=0.97), with a sensitivity of 99.57% and a specificity of 84.61%, and it showed the best discriminatory ability to distinguish "confirmed case" from "suspected case" or "negative case" at M=12 (AUC=0.938), with a sensitivity of 87.93% and a specificity of 85.98%. Conclusion This method provides reference and basis for intelligent identification and evaluation of big data on liver injury-related ADR and is expected to effectively reduce the burden of manual processing of ADR big data and provide effective tools and methodological demonstration for early risk signal identification and warning of liver injury-related ADR.

Objective To evaluate the complications of the Pipeline embolization device in treating complex cerebral aneurysm. Methods Consecutive data of 53 patients who suffered from complex cerebral aneurysm and underwent Pipeline device treatment were retrospectively collected and analyzed. Clinical and imaging data including aneurysm location, type, size and the using of coils, were recorded to investigate the complications. Results Pipeline embolization device was successfully implanted, and 27 patients were combined with coils. Five complications occurred in the 1-month perioperative stage, of which, 1 was disable and 1 was fatal. Two non-disability complications occurred in the later stage beyond 1 month, of which, 1 was cerebral infraction and 1 was intraparenchymal hemorrhage. The Logistic regression analysis demonstrated that the posterior circulation location, types, large size and the using of coils were not statistically significant risk factors for complications. The median imaging follow-up for 43 patients with 58 aneurysms was 6 months, the complete and sub-complete occlusion rate of aneurysms was 74.1％ (43 / 58) and 3 non-symptomatic stenosis occurred in the patients with Pipeline embolization device. Conclusions The occlusion rate of Pipeline embolization device in treating Chinese complex cerebral aneurysm is high , but another further research should be done for the mechanism and the prevention methods of the complications.

Objective To explore the correlation of caries susceptibility of patients with the immediate tooth polish,application of fluoride,and the patients' oral hygiene habits after interproximal enamel reduction (IER) in clinical practice.Methods The present study retrospectively collected 45 cases of IER (18 males and 27 females) in 196 tooth sites.Each sample was examined clinically and radiologically to obtain the incidence of caries,and the outcome was correlated with amount of IER,tooth polish,application of fluoride,and the brushing method and frequency for statistical analysis.Results The present study showed that there was no statistical significance among the amount of IER,the site of IER,the patients' brushing method,and the gender with the susceptibility of caries.However,there was statistical significance among the application of fluoride,tooth polish and brushing frequency with the susceptibility of caries.Conclusions The current research suggests that it is desirable to polish tooth and apply fluoride for patients with IER in clinical practices.In the meanwhile,the clinician should pay attention to patients' oral hygiene habits,especially brushing frequency,due to the positive correlation between the brushing frequency and incidence of caries.
