This article reports a postcraniotomy patient with renal insufficiency and electrolyte imbalance who developed ventilator-associated pneumonia caused by extensively drug-resistant Klebsiella pneumoniae.According to the patient's pathophysiological characteristics,bacterial epidemiological characteristics,and bacterial culture results,combined with the latest guidelines and the pharmacokinetic/pharmacodynamic characteristics of antibiotics,a full-dose ceftazidime/avibactam regimen was initially suggested by the clinical pharmacist,and which was adopted by doctor.When the effect of ceftazidime/avibactam was poor and no guideline-recommended alternatives were available,the clinical pharmacist,in conjunction with clinical experience,proposed a combination therapy of colistin sulfate and tigecycline,with the implementation of adverse reaction monitoring and mucin sulfate blood concentration monitoring.Finally,the pneumonia was effectively controlled,the inflammatory indicators such as temperature and the white blood cell count returned to normal,no adverse drug reactions occurred,and the patient was successfully transferred to the rehabilitation institution.Clinical pharmacists stay updated on the latest medication knowledge both domestically and internationally,recommend advanced drug treatment protocols for clinical practice,assist in managing severe infections,and play an important role in the clinical team.

Gastric cancer (GC) is characterized by high morbidity and mortality rates. Chinese agarwood comprises the resin-containing wood of Aquilaria sinensis (Lour.) Gilg., traditionally utilized for treating asthma, cardiac ischemia, and tumors. However, comprehensive research regarding its anti-GC effects and underlying mechanisms remains limited. In this study, Chinese agarwood petroleum ether extract (CAPEE) demonstrated potent cytotoxicity against human GC cells, with half maximal inhibitory concentration (IC50) values for AGS, HGC27, and MGC803 cells of 2.89, 2.46, and 2.37 μg·mL-1, respectively, at 48 h. CAPEE significantly induced apoptosis in these GC cells, with B-cell lymphoma-2 (BCL-2) associated X protein (BAX)/BCL-2 antagonist killer 1 (BAK) likely mediating CAPEE-induced apoptosis. Furthermore, CAPEE induced G0/G1 phase cell cycle arrest in human GC cells via activation of the deoxyribonucleic acid (DNA) damage-p21-cyclin D1/cyclin-dependent kinase 4 (CDK4) signaling axis, and increased Fe2+, lipid peroxides and reactive oxygen species (ROS) levels, thereby inducing ferroptosis. Ribonucleic acid (RNA) sequencing, real-time quantitative polymerase chain reaction (RT-qPCR), and Western blotting analyses revealed CAPEE-mediated upregulation of heme oxygenase-1 (HO-1) in human GC cells. RNA interference studies demonstrated that HO-1 knockdown reduced CAPEE sensitivity and inhibited CAPEE-induced ferroptosis in human GC cells. Additionally, CAPEE administration exhibited robust in vivo anti-GC activity without significant toxicity in nude mice while inhibiting tumor cell growth and promoting apoptosis in tumor tissues. These findings indicate that CAPEE suppresses human GC cell growth through upregulation of the DNA damage-p21-cyclin D1/CDK4 signaling axis and HO-1-mediated ferroptosis, suggesting its potential as a candidate drug for GC treatment.

ObjectiveThe antitumor activity of sesquiterpenoid M36 isolated from Myrrha against human hepatoma HepG2 cells was investigated in this study. MethodHepG2 cells were treated with M36 at different concentrations (0, 2, 4, 6, 8, 10 μmol·L-1). Firstly, the effects of M36 on the proliferation of human hepatoma HepG2 cells were detected by methyl thiazolyl tetrazolium (MTT), colony formation assay, and EdU proliferation assay. Hoechst staining, flow cytometry analysis, and Western blot were used to explore the effect of M36 on the apoptosis of human hepatoma HepG2 cells. Acridine orange staining and western blotting were used to examine the effect of M36 on autophagy in HepG2 cells. Finally, Western blot was used to detect protein expression of cancer-related signaling pathways. ResultCompared with the blank group, M36 treatment significantly inhibited the proliferation of human hepatoma HepG2 cells (P<0.01), and the half inhibitory concentration (IC50) value of M36 for 48 h was 5.03 μmol·L-1, in a dose- and time-dependent manner. M36 was also able to induce apoptosis and autophagy in human hepatoma HepG2 cells. After treatment with 8 μmol·L-1 M36 for 48 hours, the apoptosis rate of HepG2 cells was (42.03±9.65)% (P<0.01). Compared with the blank group, HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h had a significant increase in cleaved poly ADP-ribose polymerase (cleaved-PARP) protein levels (P<0.01). Acridine orange staining showed that autophagy was significantly activated in HepG2 cells treated with 4 and 8 μmol·L-1 M36 for 48 h compared with the blank group (P<0.01), which was further verified by the up-regulation of microtubule-associated protein 1 light chain 3 Ⅱ (LC3 Ⅱ). Western blot results showed that compared with the blank group, the levels of phosphorylated extracellular regulated protein kinase (p-ERK), phosphorylated p38 mitogen-activated protein kinase (p-p38 MAPK), phosphorylated c-Jun N-terminal kinase (p-JNK), and its downstream nuclear transcription factors c-Jun and p-c-Jun protein were significantly increased in M36 group (P<0.05, P<0.01). The mechanism may be related to the up-regulation of MAPK signaling pathway. ConclusionThe sesquiterpenoid M36 isolated from Myrrha inhibits the proliferation of human hepatoma HepG2 cells and promotes apoptosis and autophagy, which may be related to the activation of the MAPK signaling pathway.

bjective To analyze the drug resistance screening status and drug resistance influencing factors of high-risk groups of drug-resistant pulmonary tuberculosis in Qingdao, and to understand the inclusion of rifampicin patients in treatment, so as to provide a reference for the prevention and treatment of drug-resistant pulmonary tuberculosis. Methods The medical records of 726 cases of drug-resistant pulmonary tuberculosis among high-risk populations registered in Qingdao from 2018 to 2022 were obtained from the National Health Insurance Information System of the China Center for Disease Control and Prevention. The drug resistance to five anti-tuberculosis drugs, namely isoniazid (INH), rifampicin (RFP), ethambutol (EMB), levofloxacin (Lfx), and amikacin (Am), in the high-risk populations of drug-resistant pulmonary tuberculosis was analyzed. Univariate and multivariate logistic regression were used toidentify factors influencing rifampicin resistance, and the detection and inclusion of treatment for rifampicin-resistant patients were evaluated. Results Of the 726 subjects, 278 were drug-resistant, with a total drug resistance rate of 38.29%. The drug resistance for the five anti-tuberculosis drugs in descending order was: INH 25.90%(188/726), RFP 22.87%(166/726), Lfx 14.19%(103/726), EMB 11.29%(82/726), Am 2.48%(18/726). Analysis of the drug resistance spectrum showed that among those resistant to one drug, RFP was most common, accounting for 13.67% (38/278); among those resistant to two drugs, INH+RFP was predominant, accounting for 15.83% (44/278); among those resistant to three drugs, INH+RFP+Lfx was most frequent, at 7.19% (22/278); and among those resistant to four drugs, INH+RFP+EMB+Lfx was highest, at 6.12% (17/278). Multivariate logistic regression analysis of rifampicin resistance showed that compared with patients under 25 years of age, the risk of developing rifampicin resistance was lower in the groups aged 45 to under 65 and those aged 65 and above (OR=0.356, 95%CI: 0.181-0.700; OR=0.352, 95%CI: 0.170-0.729). Compared with migrant patients in other provinces, local patients from within the same county or district had a lower risk of developing rifampicin resistance (OR=0.599, 95%CI:0.383-0.962). Compared with patients who were smear-positive at the end of the second month of initial treatment, the risk of developing rifampicin resistance was higher in patients with relapse/return, failure of retreatment/chronic, and other categories of patients (OR=9.380, 95%CI:3.717-23.671;OR=25.749, 95%CI:8.037-82.490; OR=36.651, 95%CI:8.438-159.201). Conclusions The situation of drug-resistant pulmonary tuberculosis in Qingdao cannot be ignored. Individuals under 25 years old, migrants from other provinces, and patients with relapse/return, failure of retreatment/chronic, and other categories are significant risk factors for developing rifampicin resistance in the high-risk groups of drug-resistant pulmonary tuberculosis.
