Metabolic homeostasis is a basic function necessary for the survival of the organism. α1-acid glycoprotein (AGP) is an acute phase protein with a glycosylation degree of up to 45%. It has high affinity and low capacity. Although the biological role of AGP is not fully understood, it has been proven that it can regulate immunity and metabolism, and play an important role in transporting drugs and maintaining capillary barrier function. In this review, the structural characteristics, biochemical characteristics and the regulation of AGP expression were reviewed, with emphasis on the regulatory role of AGP in metabolism, suggesting that AGP may be a potential key factor in metabolic pathways, which provides a new research direction for metabolic diseases.

  Objective  Nicotinamide phosphoribosyltransferase (Nampt) is a new therapeutic target for ischemic stroke. The aim of this study was to investigate protective effect of liver-derived Nampt on ischemic stroke.   Methods  Liver-specific Nampt knockout mice were generated using the Cre/loxP system. NamptloxP/loxP mice were crossed with liver-specific Cre recombinase expression mice (Alb-Cre), and the progeny genotypes were identified by polymerase chain reaction. Body weight of knockout mice and control mice were measured. Nampt in liver and brain was determined by Western blot assay. Middle cerebral artery occlusion (MCAO), a classical ischemic stroke model, was generated in liver-specific Nampt knockout mice and control mice by electrocoagulation. After 24 h of modeling, neurological deficit scores of each group were evaluated and TTC staining was performed to determine the cerebral infarction volume. The level of plasma Nampt in each group was determined by ELISA.   Results  Liver-specific Nampt knockout mice with the genotype of NamptloxP/loxPAlb-Cre were successfully constructed. The hepatic Nampt expression in knockout mice was significantly decreased by 74.2% compared to control mice, while there was no significant difference in the expression of brain Nampt protein between the knockout group and the control group. Specific knockout of liver Nampt gene expression had no effect on the body weight of mice. Under normal physiological conditions, there was no significant difference in plasma Nampt levels between liver-specific Nampt knockout mice and control mice of the same gender. 24 h after MCAO modeling, there were no significant differences in neurological deficit scores, cerebral infarct volume and plasma Nampt concentration between liver-specific Nampt knockout group and control group.   Conclusion  Liver-specific Nampt knockout mice are successfully constructed. Liver-derived Nampt has no significant protective effects on ischemic stroke.

2022, 40(1): 20-27, 52. doi: 10.12206/j.issn.1006-0111.202105078
Abstract(2513) HTML (782) PDF (1886KB)(15)
  Objective  To explore the potential mechanism of Erchen decoction in the treatment of obese polycystic ovary syndrome and obese infertility, in order to provide theoretical basis for “treating different diseases with same method”.   Methods  The active ingredients and targets of Erchen decoction were obtained from TCMSP database, and the targets of obese polycystic ovary syndromes and obese infertility were obtained from GeneCard database. Active ingredient-target network was constructed by Cytoscape 3.7.1, and protein-protein interaction network and core target were obtained from STRING. GO and KEGG enrichment analysis were performed by Cytoscape 3.7.1 and online software.   Results  125 ingredients and 218 targets of Erchen decoction were obtained. There were 2 783 target genes for obese infertility and 2 962 target genes for obese polycystic ovary syndrome. Erchen decoction has a total of 117 target genes in the treatment of obese infertility and obese polycystic ovary syndromes, which proves the principle of “treating different diseases with same method”. Potential active ingredients include quercetin, kaempferol, naringin, baicalin and formononetin. PPI showed that STAT3, JUN, AKT1, MAPK3, MAPK1, MAPK14, IL-6 and FOS were the core targets of “treating different diseases with same method”. Molecular docking results showed that quercetin, kaempferol, etc. had good binding ability with JUN. GO and KEGG enrichment analysis showed that AGE-RAGE signaling pathway, IL-17 signaling pathway and endocrine resistance might be the key pathways for the “treating different diseases with same method” of Erchen decoction.   Conclusion  Erchen decoction treating "different diseases with same method" involves same targets and same pathways, which can provide reference for future experimental research.

  Objective  To explore the effect of circadian rhythm genes on flavonoids biosynthesis in safflower and its molecular mechanism.  Methods  Based on the transcriptome and metabolomic database of safflower corolla, we screened the circadian rhythm genes that correlate with biosynthesis of flavonoids in safflower. qPCR was used to quantify the expressions of circadian rhythm genes in different flowering stages at different time points in a single day. LC-MS was performed to determine the accumulation of flavonoids. The correlation between them was analyzed as well. Yeast Two-Hybrid experiment was used to verify the interactive proteins of these genes.  Results  Seven circadian rhythm genes PRR1, PRR2, ELF3, FT, PHYB, GI and ZTL were obtained. PRR1 gene was positively correlated with flavonoids accumulation (r≥0.7). The full length of PRR1 is 3 201 bp, encoding 421 amino acids, which is highly homologous with rice OsPRR73 gene and named as CtPRR1 (GenBank accession number: MW492035). CtPRR1 was mainly expressed in flowers, and the expression level increased in the daytime and declined in the evening gradually. Correspondingly, the content of flavonoids showed an opposite variation. Both of them displayed a circadian rhythm with a negative correlation (r≥−0.7). In addition, 2 heat shock proteins along with 3 AP2 transcription factors interacting with CtPRR1 protein were obtained via Yeast Two-Hybrid experiment.  Conclusion  CtPRR1 negatively regulated the safflower flavonoids accumulation in a circadian rhythm way, which may be affected by these interacting proteins.

2022, 40(1): 70-75. doi: 10.12206/j.issn.1006-0111.202101009
Abstract(6430) HTML (1561) PDF (1468KB)(59)
  Objective  To evaluate the analgesic effect of tetrodotoxin (TTX) in four types of acute pain models and provide experimental support for its rational application.  Methods  Mice or rats were intramuscularly pretreated with morphine (1 mg/kg) or TTX (0, 0.5, 1, 2, 4 and 8 μg/kg) 40 min before acetic acid writhing test, formalin stimulation test, hot plate test or tail flick test. Pain response or pain threshold were recorded, and inhibition rate was calculated during the tests. The arachidonic acid of serum was determined by Elisa.  Results  Significant analgesic effects were observed with morphine in all four acute pain models. TTX dose-dependently reduced the number of writhing induced by acetic acid and inhibited the pain response induced by formalin during phase I and phase II, with the highest inhibition rate of more than 80.00% in two pain models. TTX showed analgesic effect in tail flick test and hot plate test, with the highest inhibition rate of 25.00% and 19.79%, respectively. Both acetic acid and formalin increased arachidonic acid in animal serum, but TTX had no significant inhibitory effect on the releasing of arachidonic acid.  Conclusion  TTX showed significant analgesic effect in the chemical stimulation pain models induced by acetic acid and formalin, but limited analgesic effect was observed on the physical stimulation pain model induced by heat (hot plate and hot water). TTX may produce analgesic effect by blocking the inflammatory mediators mediating pain response.

Abstract(3260) HTML (1074) PDF (927KB)(49)
  Objective  To understand the clinical features and therapeutic methods for calcineurin inhibitor-induced pain syndrome (CIPS) in kidney transplant recipients.  Methods  The related articles or abstracts from January 1991 to December 2020 were obtained by searching PubMed, Google Scholar, CNKI, Wanfang and VIP databases. The reviews, duplicate literatures and the articles involved in non-kidney transplant recipients were excluded. 11 full papers were included with 15 case reports.  Results  The average age of patients at the time of diagnosis of CIPS was (44.6±8.31) years, and the 53.3% of the patients was male. The average appearance time of CIPS was (2.42±3.07) months after kidney transplantation. CIPS mainly affected bilateral hands, elbows, wrists, knees, ankles, feet and back. The patients had normal or elevated trough concentrations of calcineurin inhibitors (CNIs) when CIPS occurred. Some patients had elevated alkaline phosphatase, parathyroid hormone, blood calcium, C-reactive protein levels, and abnormal phosphorus levels, while rheumatoid factor and uric acid levels were normal. CIPS symptoms in most patients disappeared with dose reduction of CNIs, change to different class of CNIs, pamidronate IV injection, pregabalin, calcium channel antagonists, etc. The average recovery time was (4.43±3.31) months.  Conclusion  The most effective treatment for CIPS is to reduce the dose of CNIs and replace immunosuppressants. Other treatments include GABA analogs, intravenous pamidronate, calcium channel blockers and conservative therapy.

Abstract(2339) HTML (789) PDF (847KB)(21)
  Objective  To evaluate the effects of antihypertensive drugs on renal function after percutaneous transluminal coronary angioplasty.  Methods  A retrospective analysis was performed on 193 patients who underwent percutaneous transluminal coronary angioplasty and took antihypertensive drugs regularly. Those patients were admitted to Nanjing Drum Tower Hospital during January 2020 to December 2020. The patients were divided into ACEI/ARB group, β-blockers, calcium channel blockers and hydration control group. All patients received routine hydration during the perioperative period. The changes of serum creatinine (Scr), blood urea nitrogen (BUN), estimated glomerular filtration rate(eGFR) and endogenous creatinine clearance rate (Ccr) before and after operation were compared.  Results  The incidence of CIN was 0% in four groups. Compared with the preoperative, there was no significant change in Scr and Ccr in every group. Except for the hydration control group, the BUN levels in three treated groups were reduced after postoperative. Specifically, the BUN reduction in β-blockers group has statistically significant difference compared to the hydration control group and CCB group. In addition, eGFR levels were significantly reduced in the β-blockers group. Preoperative Scr and Ccr levels in patients with high blood pressure (SBP≥140 or DBP≥90) were significantly different from the patients with normal blood pressure (SBP<140 and DBP<90).  Conclusion  The use of ACEI/ARB and CCB before percutaneous transluminal coronary angioplasty had no effect on renal function in the short term. β-blockers can slightly reduce renal function, especially in patients with high blood pressure, who should receive special attention.

  Objective  To provide direction for the improvement of quality control of hospital preparations and ensure the safety for clinical use by analyzing the hospital preparation deviations in recent three years.  Methods  A retrospective analysis on 59 minor hospital preparation deviations from 2017 to 2019 was conducted. Brainstorming, fishbone drawing and, Minitab software were used to analyze the root causes of deviations from five aspects: personnel, machine, materials, methods and environment. The preventive and corrective measures were implemented. The results were evaluated.  Results  1 significant deviation (1.7%), 24 major deviation (40.7%), and 34 minor deviation (57.6%) were identified among the 59 casses of preparation deviation. With the implementation of preventive and corrective measures, the total number of deviations in 2018 was significantly reduced compared to that in 2017. The total number of deviations in 2019 was about the same as that in 2018. The human factors need to be focused.  Conclusion  The pharmaceutical preparation deviations in our hospital have been reduced. The further quality improvements for pharmaceutical preparations will be carried out by following the regulations of pharmaceutical production quality management standards and pharmaceutical production supervision and administration measures.
