ABSTRACT

OBJECTIVE:To study the anti-inflammatory effects of Yuyang capsule on bacterial dermatitis model rats and its effect on TLR/NF-κ B pathway. METHODS:Minimum inhibition concentration (MIC)and minimal bactericidal concentration (MBC)of Yuyang capsule against Staphylococcus aureus were determined by microdilution test. Totally 50 SD rats were randomly divided into model group ,positive control group (amoxicillin and clavulanate potassium ,120 mg/kg as amoxicillin ),Yuyang capsules high-dose ,medium-dose and low-dose groups (according to MIC ),with 10 rats in each group. The model of bacterial dermatitis was established by using the burned skin of rats infected with S. aureus . 24 h after modeling ,administration groups were intragastrically given the corresponding drug ,and model group was intragastrically given the same amount of normal saline ,once a day,for consecutive 7 days. The skin healing rate was calculated on the 1st,3rd,5th and 7th day of administration ,and the scab formation,decrustation and healing were recorded. The contents of IL- 1β,IL-6,IL-10,TNF-α,hydroxyproline(HYP),collagen Ⅰ(Col Ⅰ)and Col Ⅲ in skin tissue were detected by ELISA. Morphology changes of skin tissues were observed by HE staining. The ultrastructure was observed by transmission electron microscope. Protein expression of TLR 2,TLR4 and p-NF-κB p65 were detected by Western blotting assay. RESULTS :MIC and MBC of Yuyang capsule were 25 mg/mL and 50 mg/mL,respectively. Dose of Yuyang capsules high-dose ,medium-dose and low-dose groups were set at 600,300,150 mg/kg. Compared with model group,scab appeared on the injured skin 3 days after administration in Yuyang capsule high-dose and medium-dose groups ,and decrustation appeared on the injured skin of part mice 5-7 days after administration ;the skin healing rate of the positive control group,Yuyang capsule high-dose and medium-dose groups were all significantly increased at each time point. The contents of IL- 1 β,IL-6,IL-10 and TNF-α,pathological score ,protein expression of TLR 2,TLR4 and p-NF-κB p65 were decreased significantly (P<0.05 or P<0.01);the pathological changes such as inflammatory cell infiltration in skin tissue were improved. The contents of HYP,Col Ⅰ and Col Ⅲ were increased significantly in positive control group and Yuyang capsule high-dose group (P<0.05 or P<0.01). There was no statistical significance in most above indexes in positive control group ,Yuyang capsule high-dose and medium-dose groups (P>0.05). CONCLUSIONS :Yuyang capsule can promote skin healing of bacterial dermatitis model rats and shows certain anti-inflammatory effects ;the mechanism may be related to inhibiting TLR/NF-κB signaling pathway and reducing inflammatory response.

ABSTRACT

OBJECTIVE@#To establish a clinically applicable model of rapid identification of adverse drug reaction program (RiADP) for risk management and decision-making of clinical drug use.@*METHODS@#Based on the theory of disproportion analysis, frequency method and Bayes method, a clinically applicable RiADP model in R language background was established, and the parameters of the model were interpreted by MedDRA coding. Based on the actual monitoring data of FDA, the model was validated by the assessing hepatotoxicity of lopinavir/ritonavir (LPV/r).@*RESULTS@#The established RiADP model included four parameters: standard value of adverse drug reaction signal information, empirical Bayesian geometric mean value, ratio of reporting ratio and number of adverse drug reaction cases. Through the application of R language parameter package "phViD", the model parameters could be output quickly. After being encoded by MedDRA, it was converted into clinical terms to form a clinical interpretation report of adverse drug reactions. In addition, the evaluation results of LPV/r hepatotoxicity by the model were matched with the results reported in latest literature, which also proved the reliability of the model results.@*CONCLUSIONS@#In this study, a rapid identification method of adverse reactions based on post marketing drug monitoring data was established in R language environment, which is capable of sending rapid warning of adverse reactions of target drugs in public health emergencies, and providing intuitive evidence for risk management and decision-making of clinical drugs.

ABSTRACT

Objective@#To investigate the anti-inflammatory effect of hesperetin (HSP) on lung damage induced by paraquat (PQ) in rats by detecting the levels of inflammatory makers in rat lung tissues.@*Methods@#140 Wistar male rats were randomly divided into negative control group, HSP control group, HSP control group, paraquat model group, pirfenidone (PDF) positive control group, and 100, 200, 400 mg/kg HSP treatment groups. All groups were exposed to 50mg/kg paraquat by oral gavage except for the negative control group and HSP control group. After 24 hours, the rats in each group were given drug intervention once daily. 10 rats were randomly sacrificed at 7th day and 28th day after exposure to paraquat respectively. 3 rats were randomly selected from them and HE, Masson staining were used to observe the pathological changes in the lungs of each group. Each group randomly selected 6 rats at two time points to detect the levels of TGF-β1, TNF-α, IL-4, IL-10, IL-1β and IFN-γ in rat lung tissues.@*Results@#Histopathological examination found that the lung injury were reduced in the rats of PDF positive control group and all HSP treatment groups. Compared with the negative control group, the levels of TGF-β1, IL-1β, TNF-α, IL-4, and IL-10 in rat lung tissues were significantly increased (P<0.05, P<0.01) after PQ exposure at two points in time, and there was no significant difference in the level of IFN-γ in lung tissues compared with the negative control group (P>0.05) . The levels of TGF-β1, IL-1β, IL-4, IL-10 and TNF-α in the lung tissues of rats on the 7th day in different dose treatment groups of HSP were reduced compared with those in the PQ model group with varying degrees (P<0.05, P<0.01) . The level of IFN-γ in lung tissues of rats were not significantly different from that of model group (P>0.05) . The levels of TGF-β1 and TNF-α in lung tissue of rats on the 28th day in PDF positive control group and different dose treatment groups of HSP were reduced compared with those in the PQ model group with varying degrees (P<0.05, P<0.01). The levels of IFN-γ in the rat lung tissues were increased compared with those in the PQ model group (P<0.05). Besides, there were no significant in the levels of IL-1β, IL-4 and IL-10 in lung tissues compared with PQ model group (P>0.05).@*Conclusion@#HSP can reduce lung damage induced by PQ in rats by inhibiting the release of inflammatory factors and promoting the secretion of anti-inflammatory factors.

ABSTRACT

Chemotherapy is considered a high-risk procedure where system failures are more likely to occur. Failure mode and effects analysis [FMEA] is a systematic, multidisciplinary team-based approach to error prevention. We described our experience of using FMEA as a prospective risk-management technique throughout the chemotherapy process. The occurrence, detectability and severity were assessed. Fifteen potential risk factors associated with 10 failure modes were identified. Improvement measures were proposed according to risk priority number. A computerized physician order entry [CPOE] and complete prescription audit system [CPAS] were introduced to reduce potential risks during chemotherapy. Introduction of this system was associated with a decrease from 2.60% to 0.60%. As a result, FMEA is a useful tool to evaluate potential risk in healthcare processes

ABSTRACT

In many industrialized countries, clinical pharmacy has developed into a separate discipline and become a vital part of inpatient care in hospitals. However, as compared to many established branches of medicine, clinical pharmacy is still in its infancy, with much room for growth, improvement, and recognition by both the medical community and patients. In this study, a widely-recognized development strategy analysis tool, Strength, Weakness, Opportunity and Threat [SWOT], was used to systematically address several key issues to the development of clinical pharmacy in China. This analysis aims to provide feasible recommendations for the development of clinical pharmacy in China by identifying current problems and growth opportunities. Full development of clinical pharmacy as a mature clinical discipline will help promote the rational use of drugs by both clinicians and patients and lead to enhanced drug efficacy and safety

ABSTRACT

To explore the influence of low light on the synthesis of carotenoids, chlorophyll and the adaptability of transgenic plants with tomato Solanum lycopersicon L. GGPS2 gene, we constructed a vector containing a GGPS2 gene with green fluorescent protein (GFP) as report gene under the control of a cauliflower mosaic virus 35S promoter and introduced it into tobacco Nicotiana tabacum L. cv. Wisconsin 38 by Agrobacterium tumefaciens-mediated transformation. PCR analysis of the DNA from kanamycin resistant tobacco indicated that the transgenic tobacco containing the nptII gene, SlaGGPS2 gene and without contamination of Agrobacterium. We also detected the root tip of kanamycin resistant tobacco showing characteristic fluorescence. The contents of carotenoid, chlorophyll and photosynthesis of transgenic tobacco increased in comparison with wild tobacco after low light treatment. In addition, leaf mass per unit area, total dry weight, ratio of root to shoot in transgenic tobacco were all higher than that of the wild tobacco, which proved that the transgenic tobacco could increase the accumulation of biomass and promote it transport to root. The transgenic tobacco with SlaGGPS2 gene can increase the contents of carotenoid, chlorophyll, enhance the photosynthetic rate, promote the biomass accumulation and its distribution to root. Hence, the transgenic tobacco with SlaGGPS2 gene had increased low light tolerance and the SlaGGPS2 gene maybe can be used in other crops.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between semi-quantification of urine paraquat and the severity of acute paraquat poisoning, and to evaluate the prognostic value of the test in patients with acute paraquat poisoning.</p><p><b>METHODS</b>A total of 179 patients with acute paraquat poisoning were categorized into four groups according to their semi-quantification results of urine paraquat: +group (n = 36), ++group (n = 23), +++ group (n = 25), and ++++group (n = 95). The clinical features, severity of hepatic and renal injuries, respiratory failure, and clinical classification were compared between these four groups. Kaplan-Meier analysis was used to evaluate the survival rate.</p><p><b>RESULTS</b>The 60-day mortality was 45.25% (81/179). The amount of ingestion increased significantly from +group to ++++group (P < 0.05). No patient in +group was found to have serious complications, while most patients in ++++group suffered organ dysfunction or even organ failure. The incidence of acute respiratory failure, renal failure, and hepatic failure in ++++group was significantly higher than that in +group, ++group, and +++group (P < 0.05). The urine paraquat concentration was positively correlated with the clinical severity of acute paraquat poisoning (Spearman correlation coefficient = 0.720, P < 0.01). Kaplan-Meier survival analysis showed that the mortality of ++++group (73.7%) was significantly higher than that of +++group (40%), ++group (4.3%), and +group (0%) (P < 0.05).</p><p><b>CONCLUSION</b>The semi-quantification of urine paraquat is a promising test in evaluating the severity of acute paraquat poisoning. This test can be used to guide therapy and to predict the outcomes of patients suffering acute paraquat poisoning.</p>

ABSTRACT

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.

ABSTRACT

Studies on lycopene synthesis in Escherichia coli were not only able to gain the strains with high yield and less by-products, but also able to test functions of genes or gene clusters. In this article, the cDNA sequences of tomato LeGGPS2 and LePSY1 as well as the coding sequence of crtI from Erwinia uredovora, each of which was added a ribosome biding site, were controlled by T7 promoter and terminator alone or combined, and expressed in E. coli BL21 (DE3) to induce lycopene synthesis. The results show that only T7::crtI-LeGGPS2-LePSY1 expressed tri-cistronically could produce lycopene, and 2.124 mg/g dry cell weight oflycopene was obtained when fermented for 5 h at 30 degrees C after mixing 80 micromol/L IPTG at the later logarithmic phase while the seed broth of 1:50 (V/V) was inoculated into LB medium (pH 6.8) containing 3% sucrose and cultured for 8 h at 37 degrees C. The results confirmed the function of the prokaryonized LeGGPS2 and LePSY1 and their synergy with crtI, and also laid a foundation to establish an independent lycopene synthetic pathway in the tomato plastid.
