Preliminary study on the mechanism of halofuginone inhibiting the activity of HepG2 cells / 药学学报

This study aimed to investigate halofuginone's inhibitory effect and mechanism on the activity of hepatocellular carcinoma cells. HepG2 cells were used to detect the effects of halofuginone. After treatment, cell activity, cell migration, cell cycle, and cell apoptosis were detected by CCK-8, transwell, and flow cytometry, respectively. The expression levels of growth and metabolism-related factors such as citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and isocitrate deoxygenase (IDH) were detected by real-time quantitative PCR and Western blot. Compared with the control group, the activity of HepG2 cells was significantly inhibited by halofuginone (P < 0.01), the migration rate of HepG2 cells was decreased (P < 0.01), the apoptosis of HepG2 cells was induced (P < 0.01), and the cell cycle was arrested in S phase (P < 0.01). The expression levels of tricarboxylic acid key enzymes CS, IDH3, and OGDH were up-regulated, the expression level of isocitrate dehydrogenase isoenzymes IDH1 and IDH2 were down-regulation. In conclusion, halofuginone can inhibit the proliferation and migration of HepG2 cells and promote apoptosis in a dose-dependent manner, which may be due to the promotion of the aerobic metabolism of cells.

Systematic characterization and identification of the chemical constituents of the Schisandra chinensis decoction based on a hybrid scanning technique of UHPLC/IM-QTOF-MS / 药学学报

italic>Schisandra chinensis is a traditional Chinese medicine with the functions of reinforcing deficiency, strengthening, and inducing astringency, appliable to treat the chronic cough and deficiency in breath, palpitation, and insomnia, etc. A hybrid mass spectrometry scanning strategy (high-definition data-independent/data-dependent acquisition, HDDIDDA), enabling the ion mobility separation and alternating data-independent acquisition/data-dependent acquisition, was established, which, in combination with in-house library-driven automatic peak annotation workflows facilitated by the UNIFI software, was utilized to systematically characterize the multi-classes of chemical components from S. chinensis. The use of an HSS T3 column (100 mm × 2.1 mm, 1.8 μm), 0.1% formic acid in H2O-acetonitrile as the mobile phase running at the flow rate of 0.3 mL·min-1, and column temperature at 35 ℃, could enable good separation of the S. chinensis components within 42 min. HDDIDDA scan in both the positive and negative ion modes was employed for data acquisition. Based on the automatic peak annotation, reference standards comparison, MS2 data interpretation, and literature analysis, we were able to identify or tentatively characterize 105 compounds in the S. chinensis decoction, involving 56 terpenoids, 42 lignans, five glycosides, one organic acid, and one flavonoid. HDDIDDA scanning can improve the coverage of data acquisition and improve the accuracy of identification, while CCS prediction analysis provides the possibility to distinguish isomers by the ion mobility technology. The results provide reference for the intelligent material basis research of TCM.

Objective To compare effectiveness between the modified and traditional pressure-overload myocardial hypertrophy(POMH) model by abdominal aorta coarctation (AAC) method. Methods Totally 45 rats were divided into three groups(n = 15 per group), sham group, traditional group, and modified group. In the traditional group, the diameter ol the abdominal aorta was narrowed to 0. 70 mm through a midline incision for 4 weeks; in the modified group, the diameter of the abdominal aorta was narrowed above the left kidney to 0. 45 mm for 1 week, and then the narrowing was lifted postoperatively. The cardiac index, heart weight (HW) /body weight (BW) and left ventricular index, left ventricular weight (LVW)/BW were measured from the heart specimens, and the cross-sectional area of cardiac myocytes, myocardial collagen area, and myocardial collagen area Iraction were measured in the pathological sections by HE staining and Masson staining. Results Compared with the sham group, the differences in end-systolic interventricular septum thickness (IVSs), left ventricular end-systolic posterior wall thickness (LVPWs), HW/BW, LVW/BW, cardiomyocyte cross-sectional area, myocardial collagen area, myocardial collagen area fraction, and brain natriuretic peptide (BNP) expression levels were statistically significant (P0. 05). Conclusion The modified abdominal aortic constriction method used in this experiment is time-saving, stable, homogeneous and easy to replicate, and is a more ideal approach to establish a rat model of POMH.

Clinical features, risk factors and treatment of type 2 diabetes mellitus in patients with acute exacerbation of chronic obstructive pulmonary disease / 中国临床药理学与治疗学

AIM: To investigate the clinical features of acute exacerbation chronic obstructive pulmonary disease (AECOPD) of complicated with type 2 diabetes mellitus (T2DM), and analyze the related clinical features and risk factors. METHODS: This was a single-center cross-sectional study. From March 2020 to January 2023, 479 hospitalized patients with AECOPD in the department of respiratory and critical care medicine, Suining Central Hospital were included. There were 215 patients in AECOPD group and 60 patients in AECOPD with T2DM group. The collected variables included demographic data, complications, blood routine, infection index, random blood glucose, blood gas analysis and lung function. The adoption rate and constituent ratio of the basic description classification data were expressed as mean standard deviation for the normal distribution measurement data and median interquartile range for the skew distribution measurement data. T-test was used for normal distribution and non - parameter test was used for non-normal distribution. The categorical variables were tested by chi-square test. Rank sum test was used for rank variable data. Binary logistic regression model was used to investigate the independent factors associated with T2DM in patients with AECOPD. Finally, the results of logistic regression were verified and visualized by nomogram, validation curve, ROC curve and DCA curve. P0.05). The results of logistic regression were verified and visualized by Nomogram and its-associated ccurves. The MAE and AUC curves were 0.021 and 0.847 respectively, indicating that the model had good prediction consistency and accuracy. The DCA curve showed that Nomogram's risk threshold ranged from 0.01 to 0.99, suggesting that nomogram's model had better clinical predictive value. CONCLUSION: Our results showed that increased BMI, PaCO2 and random glucose, decreased blood lymphocyte, and atrial fibrillation is an independent clinical feature of AECOPD with T2DM. These results suggest that the immune function of patients with AECOPD and T2DM are more severely impaired and more likely to be accompanied by atrial fibrillation, which is a potential cause of poor prognosis in these patients. Meanwhile, this conclusion needs to be further verified in multicenter study with large sample size.

Objective To investigate the current status of radiation protection in non-medical radiation workplaces in Yantai, China, and to provide a scientific basis for occupational health management in non-medical radiation workplaces. Methods Non-medical radiation workplaces in Yantai were investigated using a questionnaire survey in 2022, including radiation source term, occupational health examination, personal dose monitoring, personal protective equipment, and radiation protection testing workplaces. Data were entered by a double-entry method and then analyzed. Results There were 56 non-medical radiation workplaces in Yantai, covering manufacturing, nonferrous metal ore mining, nuclear power plant, transportation, and technical services. There were 0 Class I radiation device, 150 Class II radiation devices, and 10 Class III radiation devices; there were 80 Class I radiation sources, 16 Class II radiation sources, 14 Class III radiation sources, 62 Class IV radiation sources, and 135 Class V radiation sources. There were 998 radiation workers, with an occupational health examination rate and personal dose monitoring rate of 98.3%. Among the 56 non-medical radiation workplaces, 47 (83.9%) were equipped with radiation protection monitoring instruments, 24 (51.1%) workplaces had verified the radiation protection monitoring instruments, with 2017 personal dose monitoring instruments and 2327 personal protective equipment in place, 42 (75%) workplaces carried out occupational health assessments, 44 (78.6%) workplaces carried out self-detection, and 53 (94.6%) workplaces carried out entrusting detections (monitoring pass rate: 100% [53/53]). The declaration rate of occupational hazard items was 87.5% (49/56). Conclusion There is still a gap between the current status and the requirements in the national regulations and standards regarding radiation protection in non-medical radiation workplaces. Therefore, the supervision and management of non-medical radiation workplaces should be further strengthened, especially the configuration and verification of radiation protection monitoring instruments.

Analysis of 10 cases of monkeypox in Changning District， Shanghai / 上海预防医学

ObjectiveTo analyze the clinical and epidemiological characteristics of confirmed cases of human monkeypox infection in Changning District， Shanghai， and to explore their clinical and epidemiological characteristics. MethodsClinical data from 10 reported cases of monkeypox in individuals residing in Changning District or identified by local medical institutions between July 20 and September 30， 2023， were collected. Epidemiological case investigations were conducted， and throat swabs， anal swabs， and rash swabs were collected by the treating medical institutions. Real-time fluorescence quantitative PCR was used for monkeypox virus nucleic acid testing， and descriptive epidemiological analysis was applied to analyze the epidemiological characteristics of the cases. ResultsAll 10 confirmed cases of human monkeypox infection were all young males with an average age of 35.4 years， all of whom belonged to the men who have sex with men （MSM） population， with no occupational clustering. The primary clinical symptoms included fever， rash， enlarged inguinal lymph nodes， and muscle soreness. Nine cases presented with a rash， and seven cases experienced fever symptoms. Among the 10 cases， one experienced fever， rash， enlarged lymph nodes， and muscle soreness； two had fever， rash， and enlarged lymph nodes； two had fever， rash， and systemic soreness； two had only a rash； one had fever or rash； and one was asymptomatic. Among the nine cases with a rash， the rash was mainly localized to the genital or anal area， with fewer cases presenting rashes on the limbs or trunk simultaneously. All cases reported a history of non-exclusive MSM behavior within 21 days before the onset of the disease. The interval between the last suspected high-risk exposure and the onset of symptoms was 4 to 10 days， with an average interval of 6.9 days. The time from the onset of fever to the appearance of a rash was 0 to 5 days， with an average of 1.87 days. ConclusionThe main clinical manifestations of human infection with monkeypox are fever， rash， and enlarged inguinal lymph nodes. The MSM population is a high-risk group for monkeypox infection， and its source of infection may be associated with MSM exposure. Early-stage symptoms are mild， leading to potential underdiagnosis. Additionally， patients may conceal information during the investigation process， which increases the difficulty of epidemic prevention and control.

CONCLUSIONS The incidence of ADR related to bevacizumab biosimilars is significantly higher than that of the original drugs， but there is no significant difference in the clinical manifestation of ADR. Clinicians can use bevacizumab biosimilars or original drugs based on the willingness of patients and their families.

Protective mechanism of amifostine on acute radiation injury by regulating gut microbiota / 中国药房

OBJECTIVE To explore the protective mechanism of amifostine on acute radiation injury mice. METHODS Thirty C57BL/6J mice were randomly divided into normal control group， model group and amifostine group （150 mg/kg）， with 10 mice in each group. Thirty minutes before irradiation， the mice in the amifostine group were intraperitoneally injected with amifostine； normal control group and model group were given constant volume of normal saline intraperitoneally； then acute radiation injury was induced by 4 Gy X-ray radiation in both model group and amifostine group. The white blood cell count （WBC）， platelet count and red blood cell （RBC） count in mice were detected 2 hours before irradiation and on days 1， 4， 7， 10 and 14 after irradiation； the changes in the proportion of WBC （neutrophils， lymphocytes and monocytes） on the 7th day after irradiation were analyzed. The 16S rRNA high-throughput sequencing was used to analyze the structure of gut microbiota in mice feces on the 7th day after irradiation， then its correlation with WBC was analyzed. RESULTS The counts of WBC on the 1st， 4th， 7th and 10th day after irradiation， platelet count on the 10th day after irradiation and RBC count on the 1st day after irradiation in the amifostine group were significantly higher than those in model group （P＜0.05）. Compared with normal control group，β diversity of gut microbiome showed significant change， relative abundance of Firmicutes increased and that of Bacteroidetes decreased in model group. Amifostine could reverse the change in β diversity of gut microbiome， and the relative abundance of Bacteroidetes and Firmicutes. The model group consisted of four distinct species， namely Allobaculum， Erysipelotrichia， Erysipelotrichales and Erysipelotrichaceae， which were significantly negatively correlated with the proportion of peripheral blood lymphocytes （P＜0.01）； amifostine group consisted of two distinct species， namely Lactobacillus murinus and L. crispatus， which were significantly negatively correlated with the proportion of neutrophils （P＜0.05）. CONCLUSIONS Amifostine significantly improves irradiation-induced injury by regulating dysbiosis of LY201816） gut microbiota.

Objective:To investigate the management of granulation tissue during surgery for infected congenital preauricular fistula and to assess the surgical outcomes. Methods:To summarize the surgical methods and the treatment of granulation methods in 140 cases of congenital preauricular fistula during the period of infection treated in our department from January 2018 to September 2022. The study divided patients into an observation group （79 patients） undergoing fistulectomy without granulation treatment, and a control group （61 patients） where fistulectomy and granulation resection were performed concurrently.. After six months of follow-up, the wound healing, recurrence rates, and the aesthetic assessment of granulation healing were evaluated using the Stony Brook Scar Evaluation Scale（SBSES）. Results:The two surgical approaches were applied to a total of 140 patients with infected congenital preauricular fistula. There was no statistical difference in wound healing and recurrence rates between the observation group and the control group. However, the observation group exhibited smaller scars. Conclusion:In cases of infected congenital preauricular fistula, surgical removal without excising granulation tissue is feasible, leading to effective healing and lesser scar formation.

Relationship between skeletal muscle mass loss and metabolic dysfunction-associated fatty liver disease among Chinese patients with metabolic dysregulation

SUMMARY OBJECTIVE: The aim of this study was to explore the correlation between skeletal muscle content and the presence and severity of metabolic dysfunction-associated fatty liver disease in patients with metabolic dysregulation in China. METHODS: A cross-sectional study was conducted among patients from the endocrinology outpatient department at Ningbo First Hospital, in Ningbo, China, in April 2021. Adult patients with metabolic dysregulation who accepted FibroScan ultrasound were included in the study. However, those without clinical data on skeletal muscle mass were excluded. FibroScan ultrasound was used to noninvasively evaluate metabolic dysfunction-associated fatty liver disease. The controlled attenuation parameter was used as an evaluation index for the severity of liver steatosis. Bioelectrical impedance analysis was used to measure the skeletal muscle index. RESULTS: A total of 153 eligible patients with complete data were included in the final analysis. As the grading of liver steatosis intensifies, skeletal muscle index decreases (men: Ptrend<0.001, women: Ptrend=0.001), while body mass index, blood pressure, blood lipid, uric acid, aminotransferase, and homeostatic model assessment of insulin resistance increase (Ptrend<0.01). After adjusting for confounding factors, a negative association between skeletal muscle index and the presence of metabolic dysfunction-associated fatty liver disease was observed in men (OR=0.691, p=0.027) and women (OR=0.614, p=0.022). According to the receiver operating characteristic curve, the best cutoff values of skeletal muscle index for predicting the metabolic dysfunction-associated fatty liver disease presence were 40.37% for men (sensitivity, 87.5%; specificity, 61.5%) and 33.95% for women (sensitivity, 78.6%; specificity, 63.8%). CONCLUSION: Skeletal muscle mass loss among patients with metabolic dysregulation was positively associated with metabolic dysfunction-associated fatty liver disease severity in both sexes. The skeletal muscle index cutoff value could be used to predict metabolic dysfunction-associated fatty liver disease.

Pharmacological Effect of Phellodendri Chinensis Cortex and Active Components on Gout： A Review / 中国实验方剂学杂志

Gout is a metabolic disease closely associated with hyperuricemia and urate deposition. Because of the complex pathogenesis， high morbidity， multiple complications， and increasingly young patients， gout has received worldwide attention. Currently， western medicine mainly treats gout by lowering the uric acid level and reducing inflammation， which， however， causes serious adverse reactions and has contraindications. Phellodendri Chinensis Cortex （PCC） is the dried bark of Phellodendron chinense， with the effects of clearing heat， drying dampness， purging fire， detoxifying， and treating sores. Studies have shown that PCC and its active components have anti-inflammatory， pain-relieving， uric acid-lowering， and anti-gout activities， with extensive sources and high safety. PCC and its active components could prevent and treat gout through multi-targets and multi-pathways， whereas the systematic review remains to be carried out. Therefore， this paper summarized the pharmacological activities and mechanisms of PCC and its active components in the treatment of gout. The available studies have shown that PCC and its active components exert the anti-gout effect by lowering the uric acid level， reducing inflammation， alleviating oxidative stress， and regulationg intestinal flora， and protecting the kidneys. Particularly， the active components represented by alkaloids contribute obviously to the therapeutic effect of of PCC. Herein， we analyzed the problems and future development of the research on PCC， aiming to provide theoretical support and a scientific basis for the research and development of new drugs against gout.

Effect of pharmacogenetic polymorphism on the antiplatelet aggregation effect of ticagrelor / 药学实践杂志

Objective To develop a pharmacogenomics study of ticagrelor in patients with acute coronary syndrome (ACS), identify the genetic factors that can predict individual differences in antiplatelet aggregation effects of ticagrelor, and provide a reference for the development of individualized regimens for ticagrelor. Methods 75 ACS patients of Chinese Han in a hospital in Fujian province in 2018 who met the entry criteria were recruited. The patient was given the tests for platelet function test, platelet aggregation rate and DNA detection. The whole exon sequencing method (WES) was used to detect the single nucleotide polymorphisms of SLO1B1, UGT2B7, P2Y12, PEAR1, ITGA2B and ITGB3. At the same time, the general clinical data of the patients were collected and recorded. The correlation between antiplatelet aggregation effects of ticagrelor and pharmacogenetic polymorphism was analyzed by one-way analysis of variance, multiple linear regression analysis and binary logistic regression analysis. Results One-way analysis of variance showed that SLCO1B1 rs2306283 mutant allele G could affect the antiplatelet aggregation effect of ticagrelor, the average platelet aggregation rate of patients carrying at least one allele G (AG+GG type) was significantly lower than that of wild homozygotes AA patients (8.07%±6.17% vs 13.88%±6.39%, P≤0.05). However, multivariate regression analysis after adjusting for confounding factors showed that SLCO1B1 rs2306283 mutant allele G was not an independent variable affecting the antiplatelet effects of ticagrelor (P>0.05). Conclusion Single nucleotide polymorphisms of genes related to ticagrelor transport receptors, targets, and platelet membrane receptors (including SLO1B1, UGT2B7, P2Y12, PEAR1, ITGA2B, ITGB3) in ACS patients of Han Chinese in Fujian province will not significantly affect the antiplatelet aggregation effect of ticagrelor, which provides a new treatment option for patients with genetic defects who are not suitable for clopidogrel.

Prevention and Treatment of Obesity Type 2 Diabetes Mellitus by Traditional Chinese Medicine Through AMPK Signaling Pathway： A Review / 中国实验方剂学杂志

Obesity type 2 diabetes mellitus （T2DM） strengthens insulin resistance （IR） and metabolic abnormalities and significantly increases the risk of heart disease， cancer， and other diseases， and it is characterized by IR and malnutrition. As a metabolic regulation center， adenosine phosphate activated protein kinase （AMPK） mainly responds to the changes in intracellular serine/threonine kinase adenosine monophosphate （AMP） levels. After its activation， AMPK converts the cell metabolism mode from synthesis to decomposition to improve energy metabolism and acts on pathological conditions such as inflammation， ischemia， obesity， and aging. In recent years， a large number of studies have found that AMPK is an important target for the treatment of obesity T2DM. Traditional Chinese medicine（TCM） monomers/extracts and TCM formulas mainly affect the mammalian target of rapamycin （mTOR）， recombinant sirtuin 1 （SIRT1）， nuclear factor erythroid 2-related factor 2 （Nrf2）， nuclear factor kappa-B （NF-κB）， and other key signaling factors by regulating the AMPK signaling pathway， so as to achieve a variety of effects such as regulating metabolism and autophagy， reducing oxidative stress and inflammatory response， and treating obesity T2DM. It also has advantages such as multiple targets， comprehensiveness， and low toxicity. The regulation of the AMPK pathway by TCM in the prevention and treatment of obesity T2DM has become an important research direction at the present and in the future， but there is no systematic summary and induction in this field. Therefore， this article attempts to summarize the composition and regulatory mechanisms of the AMPK signaling pathway in affecting obesity. It provides a review of the current research status of TCM in regulating the AMPK signaling pathway for the prevention and treatment of obesity T2DM， so as to provide a reference for the diagnosis and treatment of obesity T2DM in TCM and the development of new drugs.

ObjectiveTo investigate the effect and mechanism of Yiyi Fuzi Baijiangsan （YYFZBJ） on the apoptosis of colon cancer cell line HCT116. MethodYYFZBJ at different concentrations （0.5， 1， 2， 4， 6， 8， 10， 12， 14， 16 g·L-1） was used to intervene in HCT116 cells for 24， 48， 72 h. The cell counting kit-8 （CCK-8） method was used to determine the effect of YYFZBJ on cell proliferation in vitro. The cells were divided into a blank group， a capecitabine group（1.8 g·L-1）， and low-， medium-， and high-dose YYFZBJ groups （6， 10， and 14 g·L-1） and treated for 48 hours. Flow cytometry was used to detect the apoptosis. Hoechst 33342 staining was used to observe the apoptotic morphology of cells. Mitochondrial membrane potential （MMP） was analyzed by a mitochondrial-targeted deep-red fluorescent probe （Mito-Tracker Red CMXRos）. The expression of proteins related to the mitochondrial apoptosis pathway， such as B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cytochrome C （Cyt C）， cysteinyl aspartate-specific protease （Caspase）-9， Caspase-3， cleaved Caspase-9， and cleaved Caspase-3 was detected by Western blot. The mRNA levels of Bcl-2， Bax， Cyt C， Caspase-9， and Caspase-3 were determined by real-time polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， YYFZBJ （8， 10， 12， 14， 16 g·L-1） significantly inhibited the proliferation of HCT116 cells in vitro （P<0.05） in a dose-dependent manner. Compared with the blank group， the medium- and high-dose YYFZBJ groups and the capecitabine group showed increased apoptosis rates of colon cancer cells （P<0.05）. The YYFZBJ groups and the capecitabine group showed reduced number of colon cancer cells with significantly changed cellular morphology and cell apoptosis manifestations， such as strong dark blue fluorescence， nucleus concentration， shrinkage， and fragmentation. With the increase in the mass concentration of YYFZBJ， the blue fluorescence intensity was significantly enhanced. Compared with the blank group， the YYFZBJ groups and the capecitabine group showed reduced MMP in a dose-dependent manner， decreased protein and mRNA levels of Bcl-2， and increased protein expression of Bax， Cyt C， Caspase-9， Caspase-3， cleaved Caspase-9， and cleaved Caspase-3 and mRNA expression of Bax， Cyt C， Caspase-9， and Caspase-3 （P<0.05）. ConclusionYYFZBJ can induce the apoptosis of colon cancer HCT116 cells through the mitochondrial apoptosis pathway.
