Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Objective:To investigate the improvement effect of the freeze-dried garlic powder on acute myocardial ischemia and its effect on phosphatidylinositol 3 kinase/protein kinase B/nuclear factor erythroid 2-related factor 2 (PI3K/Akt/Nrf2) signaling pathway.Methods:SD rats were randomly divided into sham-operation group, model group, positive drug group, and garlic freeze-dried powder low-, medium-, and high-dosage groups using a random number table method, with 12 rats in each group. The garlic freeze-dried powder low-, medium-, and high-dosage groups were orally administered with 0.58, 1.16, and 2.32 g/kg of garlic freeze-dried powder solution, the positive reference drug group was orally administered with 0.26 g/kg of compound Danshen tablet solution, and the model group and sham-operation group were orally administered with equal volumes of distilled water once a day for 14 consecutive days. Except for the sham-operation group, all other groups were prepared with acute myocardial ischemia models in rats by ligating the left anterior descending coronary artery. Electrocardiogram testing was performed. The incidence of ventricular premature beats, ventricular tachycardia, and ventricular fibrillation in each group was counted. Myocardial infarction was observed through TTC staining, and the myocardial infarction rate was calculated; serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), LDH, cardiac troponin T (cTnT), total antioxidant capacity (T-AOC), SOD, MDA, IL-1β, TNF-α levels were detected, and Western blot was used to detect myocardial tissue p-PI3K, p-Akt, Nrf2, HO-1 and Keap1 proteins.Results:Compared with the model group, the incidence of premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation in rats in each treatment group was reduced. Compared with the model group, the positive drug group and garlic freeze-dried powder medium- and high-dosage groups showed a decrease in myocardial infarction rate in rats ( P<0.05); compared with the model group, the levels of serum T-AOC and SOD in each treatment group increased ( P<0.05 or P<0.01), while the level of MDA decreased ( P<0.05 or P<0.01); the levels of CK, LDH, cTnT, IL-1β, and TNF-α in the serum of rats in the positive drug group and garlic freeze-dried powder high-dosage group decreased ( P<0.05 or P<0.01), while the expressions of p-PI3K, p-Akt, Nrf2, and HO-1 proteins in myocardial tissue increased ( P<0.05 or P<0.01), and the expression of Keap1 protein decreased ( P<0.05 or P<0.01). Conclusions:Garlic freeze-dried powder can improve acute myocardial ischemia of rats by reducing the release of serum myocardial enzymes and exerting antioxidant and anti-inflammatory effects. The mechanism may be related to regulating PI3K/Akt/Nrf2 signaling pathway.

Objective To investigate the impact of various health education intervention strategies on the proper use of personal respiratory protective equipment (RPE) among workers exposed to dust. Methods Dust-exposed workers were recruited from 60 selected enterprises in Guangdong Province using cluster random sampling method. They were randomly allocated to the control, low-intensity intervention, and high-intensity intervention groups, with 358, 346, and 371 workers in each group, respectively. Workers in the control group received no designed intervention. Workers in the low-intensity intervention group received traditional plus mobile health education on the proper use of RPE. Workers in the high-intensity intervention group received all components of the low-intensity intervention, supplemented with peer education. The intervention lasted for six months. RPE usage was compared among the three groups of workers before and after the intervention. Results Workers in the control, low-intensity intervention, and high-intensity intervention groups showed higher rates of both RPE wearing and correct RPE wearing after the intervention than before it within their respective groups (RPE wearing rate: 94.1% vs 99.2%, 95.7% vs 100.0%, 94.6% vs 100.0%, all P<0.01; correct RPE wearing rate: 66.8% vs 91.1%, 67.3% vs 95.7%, 66.6% vs 96.5%, all P<0.01). Post-intervention correct RPE wearing rates were highest in the high-intensity intervention group, followed by the low-intensity intervention group, and the control group, with the percentage of 96.50%, 95.66% and 91.06%, respectively (P<0.01). Binary logistic regression analysis result showed that different intervention strategies affected the correct use of personal RPE among dust-exposed workers after adjusting for gender, age, and other confounding factors (P<0.05). Compared with the control group, the rates of correct RPE use increased in the low-intensity intervention group and the high-intensity intervention group (odd ratio was 2.14 and 3.01; 95% confidence interval was 1.12 - 4.10 and 1.53 - 5.91, respectively). Conclusion The implementation of traditional plus mobile health education interventions on the proper use of RPE can promote correct RPE utilization among dust-exposed workers, and integrating peer education further enhances the intervention effectiveness.

ObjectiveTo investigate the effects of Jiaohong pills (JHP) and its prescription, Pericarpium Zanthoxyli (PZ) and Rehmanniae Radix (RR) cognitive dysfunction in scopolamine-induced Alzheimer's disease (AD) mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ, RG and JHP, respectively. The effects of JHP and its formulations were investigated by open field test, water maze test, object recognition test, avoidance test, cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry (UPLC Q-Exactive Orbitrap MS). ResultThe behavioral data showed that, compared with the model group, the discrimination indexes of the high dose of JHP, PZ and RR groups was significantly increased (P<0.05). The staging rate of Morris water maze test in the PZ, RR, high and low dose groups of JHP was significantly increased (P<0.05, P<0.01), the crossing numbers in the PZ, JHP high and low dose groups were significantly increased (P<0.05, P<0.01); the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups (P<0.01), and the error latencies were significantly increased in the JHP and its prescription drug groups (P<0.01). Compared with the model group, the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased (P<0.05, P<0.01), and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased (P<0.05), and the level of acetylcholine was significantly increased (P<0.01). At the same time, the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly (P<0.05, P<0.01). The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group, which were involved in neurotransmitter metabolism, energy metabolism, oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction, regulate cholinergic system, and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter, energy, amino acid metabolism, and improvement of oxidative stress.

ObjectiveTo study the plasma pharmacokinetics and tissue distribution of five representative components in Wujiwan, and to illustrate the difference of metabolism and tissue distribution before and after compatibility. MethodHealthy male SD rats were divided into four groups, including Wujiwan group(A group, 62.96 g·L-1), Coptidis Rhizoma group(B group, 38.4 g·L-1), processed Euodiae Fructus group(C group, 5.88 g·L-1) and fried Paeoniae Radix Alba group(D group, 18.68 g·L-1), with 65 rats in each group, and were administered the drugs according to the clinical dose of decoction pieces converted into the dose of the extracts. Then plasma, liver, small intestine and brain were taken at pharmacokinetic set time in each group after administration. Ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry was developed for the quantitative analysis of five representative components[berberine(Ber), palmatine(Pal), evodiamine(Evo), rutecarpine(Rut) and paeoniflorin(Pae)] in Wujiwan, their concentrations in plasma, liver, small intestine and brain were detected at different time, plasma samples were processed by protein precipitation, and tissue samples were pretreated by protein precipitation plus liquid-liquid extraction. Non-atrioventricular model was used to calculate the pharmacokinetic parameters of each component, and the parameters of each group were compared. ResultPharmacokinetic results of A group showed that area under the curve(AUC0-t) of the five representative components were ranked as follows:Ber and Pal were small intestine>liver>blood, Evo and Rut were liver>small intestine>plasma, Pae was small intestine>plasma, which was not detected in the liver, no other components were detected in brain except for Ber. In comparison with plasma and other tissues, peak concentration(Cmax) of Ber, Pal, Evo, and Rut were the highest and time to peak(tmax) were the lowest in the liver of A group. In plasma, the AUC0-t and Cmax of Evo and Rut were increased in A group compared with C group, tmax of Pea was elevated and its Cmax was decreased in A group compared with D group. In the liver, compared with B-D groups, Cmax values of 5 representative components except Pae were elevated, AUC0-t of Pae was decreased and AUC0-t of Evo and Rut were increased in the A group. In the small intestine, half-life(t1/2) of each representative components in A group was elevated and tmax was decreased, and Cmax of each representative ingredient except Pal was decreased, AUC0-t values of Ber and Pal were increased, whereas the AUC0-t values of Evo and Rut were decreased. ConclusionThe small intestine, as the effector organ, is the most distributed, followed by the liver. The pharmacokinetic parameters of the representative components in Wujiwan are changed before and after compatibility, which is more favorable to the exertion of its pharmacodynamic effects.

ObjectiveTo preliminarily confirm the effective anti-lung cancer sites of Momordicae Semen and Epimedii Folium and study their mechanism of action. MethodOn the basis of preliminary research, the extraction method of Momordicae Semen and Epimedii Folium was optimized and the effective parts were screened under the guidance of pharmacological effects. Different ethanol elution and water elution sites of Momordicae Semen and Epimedii Folium were obtained through adsorption and elution with D101 macroporous resin. The methylthiazolyldiphenyl-tetrazolium bromide (MTT) colorimetric assay was used to detect the effects of total drug extracts and different elution sites on the proliferation of various tumor cell lines, and to screen for the optimal elution site and tumor sensitive strains. Flow cytometry was used to detect the effect of the elution sites of Momordicae Semen and Epimedii Folium on intracellular reactive oxygen species (ROS) and apoptosis in A549 cells. Western blot was used to compare the expressions of tumor protein 53 (p53), Bcl-2-associated X protein (Bax), cysteinyl aspartate specific proteinase-3 and 9 (Caspase-3 and Caspase-9) proteins in A549 cells. ResultThe inhibitory effect of Momordicae Semen on the proliferation of A549 cells was better than the kernel of Momordicae Semen, with 50% inhibitory concentration (IC50) being (86.83±2.88) mg·L-1 and (95.10±18.13) mg·L-1, respectively. The effect of total extracts of Epimedii Folium on A549 anti proliferation IC50 value was (4.71±0.81) mg·L-1. The IC50 values of the 40%, 60%, and 80% ethanol and anhydrous ethanol eluted macroporous resins of the total extracts of Momordicae Semen and Epimedii Folium inhibiting A549 proliferation were (45.32±4.38)、 (14.95±0.73)、 (17.07±1.76)、 (14.46±2.35)、 (51.7±2.26)、 (12.37±0.67)、 (20.29±0.93)、 and (3.43±0.91) mg·L-1, respectively. Compared with the normal group, the 1∶1 combination of Momordicae Semen and Epimedii Folium inhibited A549 cell proliferation in a time-dependent and concentration-dependent manner. Compared with the normal group, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased intracellular ROS expression (P<0.01). Compared with the normal group, 12.5, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of A549 cell apoptosis (P<0.01). Compared with the normal group, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of p53 in A549 cells (P<0.01). Compared with the normal group, 12.5, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of Bax (P<0.01). Compared with the normal group, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly reduced the expressions of Caspase-3 and Caspase-9 (P<0.01). ConclusionThe anti-tumor effect of Momordicae Semen is better than that of the kernel of Momordicae Semen. The anti-tumor substances of Momordicae Semen and Epimedii Folium mainly concentrate in the 60% ethanol to anhydrous ethanol elution site. A549 cells are sensitive to the 1∶1 combination of Momordicae Semen and Epimedii Folium, which can effectively inhibit the cell proliferation. The mechanism may be related to increasing the generation of ROS in A549 cells, promoting their apoptosis, increasing the expressions of apoptotic proteins such as p53 and Bax, and reducing the expressions of Caspase-3 and Caspase-9.
