OBJECTIVE
To explore the effect of single dose and multiple doses of silibinin on the in vivo pharmacokinetics of nevirapine in rats.
METHODS
Thirty male SD rats were randomly divided into blank control group, multiple administration of low-dose group(30 mg·kg−1) , multiple administration of high-dose group(100 mg·kg−1), single administration low-dose group(30 mg·kg−1) , and single administration high-dose group(100 mg·kg−1). Blood samples were collected to determine the concentration of nevirapine and its metabolites in rat plasma after an oral administration of 10 mg·kg−1 nevirapine. The kinetic parameters of nevirapine and its metabolites in each group were calculated by DAS and analyzed statistically.
RESULTS
Compared with the blank control group, multiple doses of 100 mg·kg−1·d−1 silibinin significantly increased the AUC of nevirapine by 61.78%, Cmax by 124.62% and decreased the clearance rate to 64.11%; multiple doses of 30 mg·kg−1·d−1 silibinin significantly increased the Cmax of nevirapine by 84.85%; a single dose of 100 mg·kg−1 or 30 mg·kg−1 silibinin significantly increased the Cmax of nevirapine by 65.19% and 32.12%, respectively. The metabolic ratio of 12-hydroxy-nervirapine was decreased by 31.5% by multiple doses of 100 mg·kg−1·d−1 silibinin where the pharmacokinetic parameters of 4-carboxyl-nervirapine remained unchanged.
CONCLUSION
Silibinin significantly affects the pharmacokinetics of nevirapine in rats. The drug-drug interaction should be considered when nevirapine and silibinin are concomitant.

In the post-antibiotic era,the overuse of antimicrobials has led to a massive increase in antimicrobial resistance,leaving medical doctors few or no treatment options to fight infections caused by superbugs.The use of bacteriophages is a promising alternative to treat infections,supplementing or possibly even replacing antibiotics.Using phages for therapy is possible,since these bacterial viruses can kill bacteria specifically,causing no harm to the normal flora.However,bacteria have developed a multitude of sophisticated and complex ways to resist infection by phages,including abortive infection and the clustered regularly interspersed short palindromic repeats(CRISPR)/CRISPR-associated(Cas)system.Phages also can evolve and acquire new anti-defense strategies to continue predation.An in-depth exploration of both defense and anti-defense mechanisms would contribute to optimizing phage therapy,while we would also gain novel insights into the microbial world.In this paper,we summarize recent research on bacterial phage resistance and phage anti-defense mechanisms,as well as collaborative win-win systems involving both virus and host.

ObjectiveTo explore the influencing factors of different scores on predicting death risk of extremely low birth weight infants (ELBWI). MethodsA total of 186 cases of ELBWI admitted by the Children's Hospital affiliated to Nanjing Medical University and the Lishui Branch of the Affiliated Zhongda Hospital of Southeast University were admitted from January 1, 2019 to January 1, 2021, and 125 ELBWIs were finally included after screening by inclusion and exclusion criteria. There were 47 cases in the death group and 78 cases in the survival group. General data and the items of score for neonatal acute physiology version Ⅱ (SNAP-Ⅱ), simplified version of the score for neonatal acute physiology perinatal extension (SNAPPE-Ⅱ), clinical risk index for babies (CRIB), clinical risk index for babies Ⅱ (CRIB-Ⅱ) and the national critical illness score (NCIS) were collected. Univariate and multivariate analysis was performed and nomogram was evaluated using receiver operating characteristic curve (ROC). ResultsIt was found that systolic blood pressure, maximum inhaled oxygen concentration, BE value and birth weight were important factors in ELBWI mortality risk assessment [systolic blood pressure OR: 0.968, 95%CI: 0.938-0.999, P=0.043; maximum inhaled oxygen concentration OR: 1.020, 95%CI: 1.006-1.034, P=0.006; BE OR: 0.868, 95%CI: 0.786-0.959, P=0.005; birth weight OR: 0.994, 95%CI: 0.991-0.997, P=0.000]. ROC showed that the area under the curve of the above four variables is 0.71, and the 95% confidence interval is 0.610-0.799, which is better than CRIB score. ConclusionLower systolic blood pressure, higher inhaled oxygen concentration, higher BE and lower birthweight are important influencing factors to predict the death risk of ELBWI. The above four items should be included in the newly developed score assessment to obtain a more effective ELBWI prediction system.

Purpose:
Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis.
Materials and Methods:
RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis.
Results:
We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties.
Conclusion
Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

OBJECTIVE To evaluate the clinical efficacy and safety of XELOX chemotherapy (oxaliplatin+capecitabine) combined with antiangiogenic agent (apatinib) and immunotherapy (camrelizumab) in patients with inoperable metastatic colorectal cancer (CRC)of microsatellite stable (MSS) type. METHODS Clinical medical records of 40 patients with inoperable metastatic CRC of MSS type treated in Lishui People’s Hospital from January 2020 to January 2021 were retrospectively collected. According to the treatment plan, the patients were divided into control group (20 cases) and observation group (20 cases). Control group was given XELOX+apatinib regimen, while observation group was given XELOX+apatinib+camrelizumab regimen. Every 3 weeks was a treatment cycle, and the treatment lasted for 2 consecutive cycles. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and adverse events (AEs) were recorded for all patients. RESULTS The ORR and DCR of observation group were 65.0% and 85.0%, respectively; and the ORR and DCR of control group were 35.0% and 75.0%, respectively, with no statistical significance between 2 groups (P>0.05). The median PFS of observation group and control groups were 16.0 months and 8.0 months, respectively; and the median OS were 19.0 months and 12.5 months, respectively, with statistical significance between 2 groups (P<0.05). Each patient in both groups had at least one AEs, and the incidences of reactive skin capillary hyperplasia and hyperthyroidism in observation group (40.0%, 20.0%) were significantly higher than those in control group (both were 0) (P<0.05). The incidence of nausea and vomiting in control group (90%) was significantly higher than observation group (10%) (P<0.05). There were 14 cases (70.0%) of patients with grade 3 or above AEs in observation group, and only 5 cases (25.0%) in control group, with statistical significance between 2 groups (P<0.05). However, no severe AEs that could not be tolerated or fatal occurred in the two groups, which could be alleviated after drug withdrawal or treatment. CONCLUSIONS The efficacy of XELOX chemotherapy combined with apatinib and camrelizumab in inoperable metastatic CRC patients of MSS type is comparable to that of XELOX chemotherapy combined with apatinib, but it has certain advantages in ORR, PFS and OS, and controllable safety.
