ABSTRACT
The rol genes on pRiA4 plasmid of Agrobacterium rhizogenes are potent genes that promote secondary metabolism. Molecular breeding of Atropa belladonna can be conducted by introducing rol genes to increase tropane alkaloids (TAs) content in A. belladonna. In this study, the rolB gene was overexpressed in A. belladonna plants to study the effect of rolB gene on the biosynthesis of TAs. The phenotype, TAs content and expression levels of key enzyme genes in the pathway of TAs biosynthesis of transgenic A. belladonna were analyzed. The results showed that transgenic A. belladonna had developed root system, enlarged leaves, increased leaf fresh weight, deepened leaf color, enlarged flowers, changed flower shape, reduced pistil height and decreased pollen vitality. The content of TAs in the stems of transgenic A. belladonna was significantly higher than that of the control, and the contents of scopolamine, anisodamine, hyoscyamine can reach 2.11-2.91, 1.23-2.37 and 4.88-5.20 times of the control, respectively. Compared with the control group, the expressions of key enzymes putrescine N-methyltransferase (PMT), type III polyketide synthase (PYKS), tropinone reductase I (TRI), aromatic amino acid aminotransferase 4 (ArAT4), UDP-glycosyltransferase 1 (UGT1) and hyoscyamine 6-β-hydroxylase (H6H) in the TAs biosynthesis pathway were up-regulated, and the expression of tropinone reductase II (TRII) as a metabolic shunting gene was down-regulated. The results indicated that rolB gene enhanced TAs synthesis ability in roots and accumulation in stems of A. belladonna by enhancing metabolic flow of TAs synthesis pathway and weakening the metabolic shunt of competing pathway. This study laid a foundation for molecular breeding of A. belladonna with high-yield TAs content using rolB gene.
ABSTRACT
@#Abstract: Objective To investigate a poisoning incident caused by eating eight treasure congee, and establish liquid chromatography (LC)-mass spectrometry (MS)/MS screening method of 28 alkaloids to provide references for disposal of similar poisoning incidents. Methods LC-MS/MS was used for screening 28 alkaloids in the urine, eight treasure congee and food raw material, and the detected alkaloids were quantified. Samples were extracted with 0.4% formic acid aqueous solution and separated by a Acquity UPLC BEH C18 column (1.7 μm, 100 × 2.1 mm). Acetonitrile-0.2% formic acid aqueous solution was used as the mobile phase and gradient elution was adopted. The ionization mode was electrospray positive ionization mode, and the detection method was multi-reaction monitoring (MRM). Analytes were quantified with the external standard method. Results In the concentration range of 0-100 ng/mL, the linear correlation coefficient r were greater than 0.999 for 28 alkaloids. The recovery of 28 alkaloids in urine sample ranged from 63.0% to 105.0%, and the relative standard deviations (RSDs) were between 5.8% and 8.6%. The recovery of 28 alkaloids in eight treasure congee sample ranged from 72.0% to 109.0%, and the RSDs were between 6.3% and 9.7%. The recovery of 28 alkaloids in semen sesami nigrum sample ranged from 60.0% to 95.0%, and the RSDs were between 4.8% and 8.2%. Hyoscyamine (2 380.0 ng/mL), scopliamine (3.6 ng/mL) and rac-anisodamine (4.7 ng/mL) were detected in the patient's urine. Hyoscyamine (63.3 μg/g), scopliamine (5.7 μg/g) and rac-anisodamine (2.1 μg/g) were detected in eight treasure congee. Hyoscyamine (901.0 μg/g), scopliamine (80.0 μg/g) and rac-anisodamine (30.1 μg/g) were detected in the seed of Datura stramonium L. The ratio of scopliamine and hyoscyamine in the seed of D. stramonium was 1∶11, which complies with the characteristics of D. stramonium L. In urine sample, the proportion of scopliamine and rac-anisodamine was 0.15% and 0.20%, and hyoscyamine accounted for 99.65%. Conclusion Seed morphology, the content range and proportion of three alkaloids are all in accord with the characteristics of D. stramonium. Combined with the clinical symptoms of atropine poisoning, it can be deduced that this incident is a family food poisoning caused by accidental consumption of seed of D. stramonium L. The method can provide technical support for the clinical diagnosis and treatment of alkaloid poisoning patients, and also provide a basis for emergency detection and disposal of alkaloid poisoning events.
ABSTRACT
A 30-year-old female patient with idiopathic sudden hearing loss was treated with anisodamine hydrobromide injection.After 10 minutes of the intravenous injection of this drug,the patient suffered from hypoptyalism and taste disorder for two days.After the second medication,the patient's taste recovery time was significantly shortened by holding the ice water in mouth compared to the first time.Hypoptyalism and taste disorder were considered to be the adverse drug reaction caused by anisodamine hydrobromide injection.After withdrawal the suspected drug,the patient did not experience any further discomfort since.Although taste disorder is not life-threatening,it directly affect the patient's medication experience and quality of life,clinical awareness and attention of the adverse reactions should be increased.
ABSTRACT
Hair roots induced by Agrobacterium rhizogene produce higher levels of secondary metabolites than non-induced plants, and the enhanced metabolic capacity is driven by the rol gene. We hypothesized that rol genes can be utilized to improve the biosynthesis of tropane alkaloids (TAs) in Atropa belladonna. In this study, the rolC gene from Agrobacterium rhizogene pRiA4 plasmid, driven by a CaMV35S promoter, was overexpressed in A. belladonna. The phenotypes, TAs content and transcriptional expression of key genes in TAs biosynthesis were analyzed in transgenic A. belladonna plants. Results show that transgenic A. belladonna exhibited a well-developed root system, male sterility, higher stamen column length than pistil, early flowering, internode shortening, smaller but more flowers, increased axillary buds and lateral buds, decreased apical dominance, and long and narrow leaves as compared to wild-type plants. Transgenic A. belladonna produced more TAs than wild-type plants, with the content of hyoscyamine, anisodamine and scopolamine reaching 2.58, 3.59 and 15.77-fold that of the control group, respectively. The gene expression of putrescine N-methyltransferase (PMT), tropinone reductase I (TRⅠ) and hyoscyamine 6-β-hydroxylase (H6H), key enzymes in TAs biosynthesis, were up-regulated compared with the control group. The above results indicate that the rolC gene enhances TAs biosynthesis in A. belladonna by up-regulating the expression of key enzymes in the TAs biosynthesis pathway, laying a foundation for genetic manipulation of A. belladonna to increase TAs content by increasing rolC gene expression.
ABSTRACT
Objective@#This study aimed to examine the effects of microcirculatory dysfunction and 654-1 intervention after cardiopulmonary resuscitation on myocardial injury.@*Methods@#Landrace pigs were divided into a sham operation group (S group, n= 6), ventricular fibrillation control group (VF-C group, n= 8) and 654-1 intervention group (VF-I group, n= 8). Hemodynamics was recorded at baseline, at recovery of spontaneous circulation (ROSC), and 1 h, 2 h, 4 h and 6 h thereafter. Sidestream dark field (SDF) technology was used to evaluate and monitor the microcirculation flow index, total vessel density, perfusion vessel ratio, De-Backer score, and perfusion vessel density in animal viscera at various time points.@*Results@#After administration of 654-1 at 1.5 h post-ROSC, the hemodynamics in the VF-I group, as compared with the VF-C group, was significantly improved. The visceral microcirculation detected by SDF was also significantly improved in the VF-I group. As observed through electron microscopy, significantly less myocardial tissue injury was present in the VF-I group than the VF-C group.@*Conclusion@#Administration of 654-1 inhibited excessive inflammatory by improving the state of visceral microcirculation.

Objective:To investigate whether anisodamine can regulate the ratio of helper T helper cells/regulatory T cells (Th17/Treg) and its protective effect on animals after resuscitation.Methods:Twenty-four Beijing white minipigs were randomly divided into sham operation group (Sham group), resuscitation and normal saline group (SA group), and resuscitation and anisodamine hydrobromide group (AH group), with 8 pigs in each group. In SA group and AH group, ventricular fibrillation was induced by continuous stimulation with intraventricular electrodes for 8 minutes and then resuscitated to establish ischemia/reperfusion (I/R) model. In SA group, after cardiopulmonary resuscitation (CPR), only normal saline was intravenously infused, while in AH group, normal saline and anisodamine hydrobromide were given intravenously at the same time point. Hemodynamic indexes, arterial blood gas analysis indexes, interleukins (IL-17, IL-10) levels in venous blood and IL-17/IL-10 ratio were recorded at 6 different time points: baseline, immediately after return of spontaneous circulation (ROSC), 1 hour, 2 hours, 4 hours and 6 hours after ROSC. The animals were sacrificed at 6 hours after ROSC, and intestinal lymphatic tissues were taken to observe pathological changes under light microscope. At the same time, the levels of IL-17 and IL-10 in intestinal lymphatic tissue were measured (the ratio of IL-17/IL-10 represents the ratio of Th17/Treg cytokines) to evaluate the immune status of the resuscitated animals. The bacterial translocations of different groups were evaluated by culturing intestinal lymphoid tissue.Results:With the extension of ROSC time, the levels of IL-17 in venous blood and the IL-17/IL-10 ratio in pig blood samples continued to decrease, while the levels of IL-10 continued to increase. From 2 hours after ROSC, the IL-17/IL-10 ratio in AH group was significantly higher than that in SA group continued until at 6 hours after ROSC (0.79±0.05 vs. 0.49±0.08, P < 0.05). Light microscopy showed that the number and size of lymph nodules in the cortex of intestinal lymphatic tissue were less in AH group, compared with SA group. Compared with Sham group, the levels of IL-17 and IL-17/IL-10 ratio also decreased in intestinal lymphatic tissue at 6 hours after ROSC [IL-17 (ng/L): 155.23±0.92, 178.76±7.25 vs. 209.21±19.82, IL-17/IL-10 ratio: 1.43±0.13, 1.92±0.18 vs. 3.30±0.31, all P < 0.05], and IL-10 increased significantly (ng/L: 109.85±11.60, 93.55±81.83 vs. 63.45±0.62, all P < 0.05); IL-17/IL-10 ratio in AH group was significantly higher than that in SA group (1.92±0.18 vs. 1.43±0.13, P < 0.05). Tissue culture indicated the intestinal bacterial translocation after resuscitation, suggesting that the animals had immunosuppression and the increased risk of intestinal secondary infection after resuscitation. Compared with SA group, the risk of bacterial translocation was lower than that in AH group [62.5% (5/8) vs. 87.5% (7/8), P < 0.05]. Conclusions:Anisodamine plays an immunomodulatory role by affecting the balance of Th17/Treg cytokines in resuscitated animals, so as to reduce the risk of intestinal secondary infection and has an organ protective effect.
ABSTRACT
Abstract Intestinal ischemia/reperfusion (I/R) causes barrier impairment and bacterial influx. This study explored the protective effects of anisodamine hydrobromide (AH) on intestinal I/R injury caused by cardiopulmonary resuscitation (CPR) after cardiac arrest (CA). After successful CPR, minipigs were randomly divided into two groups (n = 8): saline and AH (4 mg/kg), and then treated with saline or AH via central venous injection, respectively. The same procedures without ventricular fibrillation initiation were conducted in the Sham group (n = 8). Levels of interferon gamma (IFN-γ) and interleukin 4 (IL-4) were measured at different time points (0, 0.5, 1, 2, 4, and 6 h) in serum and 6 h in gut associated lymphoid tissues (GALTs) after the return of spontaneous circulation (ROSC) to evaluate changes in the proportion of T-helper type 1 (Th1) and T-helper type 2 (Th2). Moreover, the positive culture rates of GALTs were examined to evaluate bacterial translocation. AH treatment markedly alleviated aberrant arterial blood gas and hemodynamics as well as intestinal macroscopic and morphological changes after CPR. Moreover, AH treatment significantly increased IFN-γ and decreased IL-4 in both serum and GALTs. Furthermore, AH treatment dramatically decreased positive bacterial growth in GALTs. AH treatment mitigated immunosuppression caused by intestinal I/R and protected the intestinal immune barrier against bacterial translocation, thereby reducing the risk of secondary intestinal infection

The fetal heart was warded to closely observe the labor process during medication. The cervical maturity,labor process time,delivery mode and postpartum situation of lying-in women,Apgar score,body mass and inci-dence of adverse reactions of newborn in 2 groups were observed. RESULTS:The lying-in women cases with no less than 9 cervi-cal maturity,natural delivery rate and 5 min newborn Apgar score in observation group were significantly higher than control group, lying-in women cases with 7-9 scores and less than 7 scores,cesarean section rate,perineal/ straight cut rate and 24 h postpartum hemorrhage were significantly lower than control group,the second,the third and total labor process were significantly shorter than control group,the differences were statistically significant(P0.05). CONCLUSIONS:Anisodamine combined with oxytocin can accelerate the cervical dilation of lying-in women with pro-longed active phase,shorten labor process,reduce cesarean section rate and improve prognosis,it did not affect the body mass of newborns,with good safety.
