ABSTRACT

Myocardial ischemia-reperfusion injury (MIRI) is a serious complication of revascularization in patients with myocardial infarction. The nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) signaling pathway plays an important role in the pathological process of MIRI. Currently,research has found that traditional Chinese medicine has a good effect on myocardial injury caused by ischemia-reperfusion. Based on the Nrf2/HO-1 signaling pathway,this article summarizes the action mechanism of traditional Chinese medicine formulas and monomers in intervening with MIRI. It is found that traditional Chinese medicine formulas (Yixin formula,Wenyang tongmai formula,Dingxin formula Ⅰ),monomers such as terpenoids (ginkgolides, astragaloside Ⅳ,ginsenosides),phenols (brazilin,hematoxylin A,resveratrol) and quinones (aloe,emodin) can alleviate MIRI by activating the Nrf2/HO-1 signaling pathway,inhibiting oxidative stress and inflammatory reactions,etc.

ABSTRACT

Gouty arthritis (GA) is a metabolic disease caused by disorders of purine metabolism and/or abnormal excretion of uric acid in the body. Its pathogenesis is mostly related to dietary structure as well as excessive intake of protein, sugar and fat, and the clinical manifestations are joint redness, swelling, heat and pain, which seriously affect the daily life of patients. Therefore, it is urgent to carry out research on anti-GA drugs. Western drugs for the treatment of GA, such as colchicine, can relieve pain in the short term, but with obvious side effects in long-term treatment. Traditional Chinese medicine has definite efficacy and high safety in the treatment of GA and is more acceptable to patients than western medicine. Modern medical research has concluded that inflammatory factors, oxidative stress, apoptosis and intestinal dysbacteriosis are closely related to the pathogenesis of GA. In-depth research has found that single traditional Chinese medicine and its compounds can regulate Toll-like receptors/myeloid differentiation factor 88 (TLRs/MyD88) signaling pathway, NLR family pyrin domain containing 3 (NLRP3) inflammasome, nuclear transcription factor-κB (NF-κB) and other inflammatory signaling pathways, and further intervene in the downstream cytokines such as interleukin-1β (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), peroxisome proliferator-activated receptor γ (PPARγ), nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-α(IκB-α) and aspartate-specific cysteine protease 1 (Caspase-1) to reduce inflammatory factors and increase anti-inflammatory factors, thereby exerting the anti-GA role. Therefore, this paper summarized and elaborated the experiments of inflammatory response mediated by traditional Chinese medicines and their compounds via regulating inflammatory signaling pathways in recent years, which provides new ideas and theoretical basis for finding more related anti-inflammatory traditional Chinese medicines for the treatment of GA.

ABSTRACT

Objective:To study the effect of the siderophore virulence gene entB on the virulence of carbapenem-resistant Klebsiella pneumonia (CRKP). Methods:CRKP-27 was selected as the experimental strain from 30 CRKP strains collected from the First Affiliated Hospital of Kunming Medical University. The knockdown strain (Δ entB) and complementing strain (C-Δ entB) were constructed by the clustered regularly interspaced short palindromic repeat-Cas9 technology, and verified by polymerase chain reaction (PCR). In order to initially understand the effect of entB on CRKP colony morphology and virulence phenotype, the colony morphology of CRKP-27, Δ entB, and C-Δ entB strains were observed and string test were tested. Draw the growth curve of the strains and determine the effect of entB on the growth of the CRKP strains. The siderophores production ability of the strains were detected quantitatively using chrome azurol S (CAS) detection solution. Mice model of inflammation was established to observe the survival rate of mice and intuitively understand the effect of entB on CRKP virulence. Results:The PCR results showed that the Δ entB strain and C-Δ entB stranin were constructed successfully. The entB has no significant effect on the colony morphology, capsule and virulence phenotype of CRKP. The growth rate of Δ entB was significantly faster than that of CRKP-27( P=0.008) and C-Δ entB ( P=0.001), which showed that entB weakened the growth ability of CRKP. Compared with CRKP-27( P=0.001) and C-Δ entB( P=0.001), the siderophore production of Δ entB was significantly decreased by 11.739 3% and 11.964 2%, indicating that entB gene increased the capacity of CRKP to produce siderophpres. In animal experiments, compared with CRKP-27( P=0.023) and C-Δ entB( P=0.024), the survival rate of mice in the Δ entB group was significantly increased, indicating that the entB increased the virulence of the CRKP. Conclusion:The siderophore virulence gene entB significantly weakened the growth ability of the strain, but clearly enhanced the siderophore production capacity and virulence of CRKP.

ABSTRACT

Objective:To evaluate the clinical efficacy of Buyang-Huanwu Decoction combined with modified Tingli-Dazao-Xiefei Decoction on the basis of conventional western medicine therapy in the treatment of chronic heart failure (CHF) with syndrome of qi deficiency and blood stasis. Methods:Seventy patients who met the inclusion criteria from November 2017 to November 2019 in Shijingshan District Hospital of Traditional Chinese Medicine were randomly divided into two groups, 35 in each group. The control group was treated with western medicine for chronic heart failure, and the treatment group was treated with Buyang-Huanwu Decoction combined with Tingli-Dazao-Xiefei Decoction on the basis of the control group. Both groups were treated for 2 weeks. The TCM syndrome scores were observed and compared before and after treatment. Minnesota Living with Heart Failure Questionnaire (MLHFQ) was used to evaluate the quality of life of patients. Lee’s Heart Failure Score was used to evaluate the severity of symptoms. The N-terminal pro-B type natriuretic peptide(NT-proBNP) was detected by ELISA. The adverse reactions during treatment were observed and the clinical efficacy was evaluated. Results:The total effective rate was 91.4% (32/35) in the treatment group and 77.1 % (27/35) in the control group, and the difference was statistically significant ( χ2=7.050, P=0.014). After treatment, the serum NT-proBNP in the treatment group [(1 725.3 ± 1 473.8) ng/L vs. (2 485.7 ± 2 164.4) ng/L; U=341.200, P=0.031] was significantly lower than that of the control group. The NT-proBNP [(54.3 ± 26.7) % vs. (35.5 ± 19.8)%; U=4.310, P=0.003] was significantly higher than that of the control group. After treatment, the TCM syndrome scores and MLHFQ scores in the treatment group were significantly lower than those in the control group ( t=3.785, 9.925, P=0.031, 0.001). During the treatment, no obvious adverse reactions were observed in both groups. Conclusion:On the basis of standardized treatment of Western medicine, Buyang-Huanwu Decoction and Tingli-Dazao-Xiefei Decoction can improve the clinical efficacy of CHF patients with qi deficiency and blood stasis syndrome, promote the repair of damaged myocardium (reduce NT-proBNP), and improve the quality of life of patients.

ABSTRACT

Objective:To evaluate the clinical efficacy and safety of oral mifepristone (10 mg/day) versus placebo in the preoperative treatment of uterine fibroids.Methods:This study was a multi-center, randomized, double-blind, placebo, parallel controlled trial. A total of 132 patients with uterine fibroids were randomly divided into study group and control group, with 66 cases in each group. The patients in the study group orally took 1 tablet/day of mifepristone (dose of 10 mg/tablet), the patients in the control group orally took 1 tablet/day of placebo, and both groups were treated for 3 months. The primary efficacy evaluation indicators were the change rate of maximum fibroid volume; the secondary efficacy evaluation indicators included amenorrhea rate, improvement of subjective symptoms and anemia; the safety evaluation indicators included the analysis of adverse events and changes in laboratory biochemical indicators.Results:At the end of treatment, the maximum leiomyoma volume was reduced by 25.97% (95% CI: -34.79%--15.95%) in the study group and reduced by 1.51% (95% CI: -13.03%-11.54%) in the control group. The change rate of the maximum leiomyoma volume before and after treatment in the study group was significantly greater than that in the control group, and the difference in the change rate of the maximum leiomyoma volume between the two groups was -24.84% (95% CI: -36.56%--10.94%), which was much higher than the 10% superiority threshold goal set by this study within the 95% CI interval. At the end of treatment, the complete amenorrhea rate [84% (52/62)], dysmenorrhea elimination rate [98% (61/62)], and menstrual blood loss disappearance rate [87% (54/62)] in the study group were significantly higher than those in the control group (all P<0.05). At the end of treatment, the mean hemoglobin [(131±13) g/L], red blood cell count [(4.5±0.4)×10 12/L] and hematocrit (0.39±0.03) in the study group were significantly increased compared with the baseline, and the differences had statistical significance (all P<0.05); after treatment, the differences in the above three indicators between the two groups had statistical significance (all P<0.01). The serum estradiol level in the study group was significantly lower than that in the control group at the end of treatment, and the difference was statistically significant ( P<0.01). There were no significant differences in follicle-stimulating hormone and cortisol levels before and after treatment between the two groups ( P>0.05). The overall incidences of any adverse event were not significantly different between the two groups (all P>0.05). Abdominal pain was the most common adverse event in the study group [9% (6/65)], but the incidence was not significantly increased compared with the control group [3% (2/64); P>0.05]. Conclusion:Compared with placebo, oral mifepristone 10 mg/day is significantly superior to placebo in reducing the size of uterine fibroids and improving anemia, without significant adverse reactions, and could be used as a drug treatment for patients with of uterine fibroids before surgery.

ABSTRACT

Objective To investigate the transmission of blaNDM-1 gene in carbapenem-resistant Citrobacter freundii. Methods A total of 18 strains of NDM-1-producing C. freundii were collected from the First Affiliated Hospital of Kunming Medical University during the period from June 2012 to October 2014. The isolates were identified and subjected to antimicrobial susceptibility testing with VITEK 2 System. Conjugation experiments, pulsed-field gel electrophoresis (PFGE) and Southern blot hybridization were performed to determine the transferability of plasmids. Results The antibiotic susceptibility results showed that all the NDM-1-producing C. freundii isolates were resistant to penicillins, cephalosporins and carbapenems. All isolates exhibited different level resistance to other antibiotics. Conjugation experiments revealed that the plasmids harboring blaNDM-1 in 13 strains were transformed into E. coli 600, and exhibited carbapenem resistance. PFGE and Southern blot hybridization found that blaNDM-1 was located on a 33.3 kb plasmid in 16 isolates and on 33.3-54.7 kb plasmid in 2 isolates. Conclusions Our findings suggest that plasmids contribute to the horizontal dissemination of blaNDM-1 gene in carbapenemresistant C. freundii.

ABSTRACT

Objective To optimize the prescription ofBaichanting Tablets by the central composite design-response surface methodology.Methods The doses of MCC, cCMC-Na, SiO2, and magnesium stearate were set as investigation factors; disintegration time and moisture rate were set as indexes. Linear equation quadratic polynomial described mathematic relationship of disintegration time and moisture rate with other four influence factors. Response surface was described according to the optimal mathematic models; the optimal prescription was chosen; predictive analysis was conducted.ResultsThe relationship of disintegration time and moisture rate with other four influence factors could not be described by linear equation. When quadratic polynomial matching was used, correlation coefficients were 0.837 9 and 0.923 1, with relatively high reliability. Optimal prescription contained 30.6%MCC, 10%cCMC-Na, 0.30%SiO2, and 0.10% magnesium stearate. The theoretical value and predicted value deviations of the disintegration time limit and moisture absorption rate were within 5%.Conclusion The predictability of the established model is good. Application of central composite design-response surface methodology can precisely optimize the prescription ofBaichanting Tablets.

Behavior test was used to detect grabbing capacity and body movement coordination capacity: three biochemical indexes (SOD, MDA, GSH-Px) were detected by biochemical process and the activity of two immune enzyme-linked indexes (IL-1β, IL-6) were detected by enzymelinked immunosorbent assay.ResultsCompared with the control group, the autonomic activity numbers of mice increased and climbing pole time decreased in the model group (P<0.05), enzymatic activity of SOD and GSH-Px decreased significantly and the contents of MDA, IL-1β and IL-6 increased obviously (P<0.01). Compared with model group, the autonomic activity numbers of mice increased and climbing pole time decreased in the Uncariae Ramulus Cum Uncis extract group and madopar group (P<0.05). Enzymatic activity of SOD and GSH-Px increased and the contents of MDA and IL-1β and IL-6 decreased (P<0.05,P<0.01).ConclusionUncariae Ramulus Cum Uncis extract can reduce neuronic apoptosis PD mice, whose therapeutic action may be realized through eliminating oxygen free radicals, improving oxidation resistance and reducing inflammatory reactions.

ABSTRACT

Objective To detect the serum levels of 25‐hydroxy vitamin D[25‐(OH)D] ,homocysteine(HCY) andβ2‐microglob‐ulin(β2‐MG) in the patients with type 2 diabetes mellitus (T2DM ) and to investigate the relationship between serum HCY and β2‐MG with 25‐(OH)D and its clinical significance .Methods A total of 139 cases of T2DM were selected anddivided into 3 groups , the normal albuminuria group for [urinary albumin to creatinine ratio (UACR)< 30 mg/gCr ,45 cases] ,microalbuminuria group (UACR ≥ 30 mg/gCr and < 300 mg/gCr ,48 cases) and massive proteinuria group (UACR ≥ 300 mg/gCr ,46 cases) according to the urinary albumin to creatinine ratio (UACR) .Other 45 individuals undergoing the physical examination were selected as the con‐trol group .The serum 25‐(OH)D level was measured by electrochemiluminescence .Serum HCY level was determined by the enzy‐matic method .Serum β2‐MG level was measured by the latex enhanced immune turbidity method .At the same time ,the biochemical indicators of FBG ,HbA1C ,serum calcium and phosphorus were measured .Results The serum 25‐(OH)D level was decreased with the increase of urinary albumin in the DM patients .And the serum 25‐(OH)D level in the microalbuminuria group and the massive proteinuria group was significantly decreased compared with the normal albuminuria group and the control group ,the difference was statistically significant(P<0 .01) .The serum HCY and β2‐MG levels in the microalbuminuria group and the massive proteinuria group were significantly increased compared with the healthy control group ,the difference was statistically significant (P<0 .05) . Conclusion The serum 25‐(OH)D level is decreased with the increase of urinary albumin in the diabetic patients .The serum HCY andβ2‐MG levels are increased with the increase of urinary albumin and serum 25‐(OH)D level is negatively correlated with the HCY andβ2‐MG levels .
