ABSTRACT

italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

ABSTRACT

@#Lung cancer is the malignancy with the highest incidence and mortality rate in China. In recent years, the popular use of low-dose computed tomography in the population has led to an increase in the detection rate of pulmonary nodules. The National Comprehensive Cancer Network (NCCN) updated and released the NCCN clinical practice guidelines in oncology for non-small cell lung cancer (version 2.2023) on February 17, 2023. This article will interpret the main updates of the new guideline and compare it with the domestic lung cancer treatment guidelines, providing new ideas for the diagnosis and treatment of lung cancer for Chinese clinicians.

ABSTRACT

The use of immune checkpoint inhibitor (ICI) has significantly improved the efficacy of different types of malignancies, but the immune-related adverse event (irAE) callsed by ICI involves multiple organs and systems, affects the treatment, threatens the health of patients and even endangers their life. Therefore, it is necessary to select biomarkers to predict and monitor the occurrence of irAE, assist in the early diagnosis of high-risk patients, and guide individualized treatment. Recent studies have shown that some certain cytokines may be involved in the genesis and development of irAE. The article provides a review of studies related to cytokines and irAE to provide a reference for clinical prediction and monitoring of irAE.

ABSTRACT

Vigabatrin-associated brain abnormalities on magnetic resonance imaging (VABAM) is a relatively rare side effect of vigabatrin, most of which are asymptomatic. However, there will be extremely rare cases with hyperkinetic disorders, myoclonus, tremor, and acute encephalopathy under certain circumstances. VABAM is often underappreciated by physicians and its accurate incidence remains unclear. A female infant who was diagnosed with infantile spasms and required adrenocorticotropic hormone therapy accompanied by various antiseizure medicines was reported. Unfortunately, she became lethargic and her spasm deteriorated gradually after vigabatrin exposure. Her brain magnetic resonance imaging revealed abnormal signals bilaterally in the dorsal midbrain, thalamus, and rostral part of the pallidum. She had a seizure amelioration and became lively as a result of vigabatrin withdrawal. In the meanwhile, magnetic resonance imaging returned to normal. Attempts were made to discover the risk factors of VABAM and potential pathogenesis. Further understanding of the disease should contribute to decreasing misdiagnosis and making precise decisions.

ABSTRACT

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

ABSTRACT

In recent years, laparoscopic surgery and robotic surgery have been widely used, and various intraoperative image navigation systems have also developed rapidly. However, the liver itself has a complex vessel and duct system, which increase the difficulty of liver surgery. The augmented reality image navigation system combines the three-dimensional reconstructed image of the liver with the real liver anatomy, which presents the specific relationship between the tumor location and the surrounding vessels for the surgeon. Compared with other intraoperative image navigation methods, augmented reality has its unique advantages. This paper provides an overview of current advances in registration technology in augmented reality image navigation system, and focuses on its applications in liver surgery, including laparoscopic surgery and robotic surgery. Finally, the technological problems and difficulties still faced at present are summarized, and future directions worth studying in this field are proposed.

ABSTRACT

Head and neck tumors often have complex anatomical structures and are adjacent to important organs. Radiation injury caused by conventional radiotherapy technology is the main dose-limiting factor. Carbon ion beam has become the most ideal radiation to replace photon due to its excellent relative biological effect and Bragg peak. By 2019, 32 000 people worldwide have received carbon ion radiotherapy (CIRT). Despite the efficient tumor killing ability of this technology, radiation injury cannot be avoided. This article reviews the types and incidence of moderate to severe radiation injury caused by CIRT in head and neck cancer to provide a comprehensive understanding of the potential risks in CIRT.

ABSTRACT

To explore the application value of whole exome sequencing (WES) in the diagnosis of prenatal and postnatal neurodevelopmental disorders (NDDs). A total of 70 patients diagnosed with NDDs who underwent WES at the Medical Genetics Center of the Maternal and Child Health Hospital of Hubei Province between June 2020 and July 2021 were retrospectively analyzed. Genomic DNA was extracted from peripheral blood samples and amniotic fluid. WES-based copy number variant (CNV) analysis was integrated into the routine WES data analysis pipeline. The results showed that a molecular diagnosis rate could be made in 21/70 (30%) cases. Of 21 positive cases, 14 (23%) cases were detected by single-nucleotide variant/small insertion/deletion (SNV/Indel) analysis, of which 12 variants were novel, 6 (9.8%) cases were detected by WES-based CNV analysis, and 1 (1.6%) case was detected by a combination of both. The diagnostic yield of WES combined with CNV analysis was higher than that of SNV/Indel analysis alone (30%, 21/70 vs. 20%, 14/70). Of the 28 prenatally diagnosed cases, 6 cases were found to have inherited parental variation for NDDs, 10 cases were found not to have the same pathogenic variation as the proband, and the remaining 12 cases were found to have no pathogenic or likely pathogenic variation that could explain the NDDs phenotype. Clinical follow-up showed that 5 families opted for abortion and the remaining had no current abnormalities. In conclusion, WES may be an effective method to clarify the genetic etiology and prenatal diagnosis of NDDs, which is helpful in assessing the prognosis to aid clinical management and reproductive guidance.

ABSTRACT

BACKGROUND@#There are few data comparing clinical outcomes of complex percutaneous coronary intervention (CPCI) when using biodegradable polymer drug-eluting stents (BP-DES) or second-generation durable polymer drug-eluting stents (DP-DES). The purpose of this study was to investigate the safety and efficacy of BP-DES and compare that with DP-DES in patients with and without CPCI during a 5-year follow-up.@*METHODS@#Patients who exclusively underwent BP-DES or DP-DES implantation in 2013 at Fuwai Hospital were consecutively enrolled and stratified into two categories based on CPCI presence or absence. CPCI included at least one of the following features: unprotected left main lesion, ≥2 lesions treated, ≥2 stents implanted, total stent length >40 mm, moderate-to-severe calcified lesion, chronic total occlusion, or bifurcated target lesion. The primary endpoint was major adverse cardiac events (MACE) including all-cause death, recurrent myocardial infarction, and total coronary revascularization (target lesion revascularization, target vessel revascularization [TVR], and non-TVR) during the 5-year follow-up. The secondary endpoint was total coronary revascularization.@*RESULTS@#Among the 7712 patients included, 4882 (63.3%) underwent CPCI. Compared with non-CPCI patients, CPCI patients had higher 2- and 5-year incidences of MACE and total coronary revascularization. Following multivariable adjustment including stent type, CPCI was an independent predictor of MACE (adjusted hazard ratio [aHR]: 1.151; 95% confidence interval [CI]: 1.017-1.303, P  = 0.026) and total coronary revascularization (aHR: 1.199; 95% CI: 1.037-1.388, P  = 0.014) at 5 years. The results were consistent at the 2-year endpoints. In patients with CPCI, BP-DES use was associated with significantly higher MACE rates at 5 years (aHR: 1.256; 95% CI: 1.078-1.462, P  = 0.003) and total coronary revascularization (aHR: 1.257; 95% CI: 1.052-1.502, P  = 0.012) compared with that of DP-DES, but there was a similar risk at 2 years. However, BP-DES had comparable safety and efficacy profiles including MACE and total coronary revascularization compared with DP-DES in patients with non-CPCI at 2 and 5 years.@*CONCLUSIONS@#Patients underwent CPCI remained at a higher risk of mid- to long-term adverse events regardless of the stent type. The effect of BP-DES compared with DP-DES on outcomes was similar in CPCI and non-CPCI patients at 2 years but had inconsistent effects at the 5-year clinical endpoints.

ABSTRACT

Objective: To estimate the risk for type 2 diabetes mellitus (T2DM) death attributed to insufficient whole grain intake in seven regions of China from 2005 to 2018. Methods: Based on China National Nutrition and Health Surveys and China Adult Chronic Disease and Nutrition Surveillance, ordinary Kriging method and locally weighted regression were used to estimate the level of whole grain intake of Chinese residents from 2005 to 2018. Based on the results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 and Chronic Diseases Risk Factors Surveillance in China, we calculated the population attributable fraction (PAF), attributable death number and attributable mortality rate of T2DM due to insufficient whole grain intake in people aged ≥20 years in different regions of China, and we used the 2010 Chinese census data to compare the changes in T2DM deaths attributed to insufficient intake of whole grains in seven regions of China. Results: The whole grain intake levels of Chinese people over 20 years old in 2002, 2010 and 2015 were 19.0 g/d, 14.3 g/d and 19.8 g/d, respectively. The estimated overall whole grain intake level was 20.1 g/d in Chinese residents in 2018, and the intake level was 19.4 g/d in men and 20.8 g/d in women. Among the seven regions, the intake level was highest in northern China (47.4 g/d) and lowest in southwestern China (6.0 g/d). In 2018, the PAF was lowest in northern China (12.8%) and highest in southwestern China (19.3%). From 2005 to 2018, the PAF varied in the seven regions, and the PAF in northeastern China fluctuated around 18.5%. Other regions showed downward trends, especially in northern China and northwestern China, decreased by 26.4% and 21.2%, respectively. Over the past 14 years, the number of attributable deaths in the seven regions showed upward trends, with the highest annual average growth rate of 6.7% in southern China and the lowest annual average growth rate of 2.4% in northern China. In 2018, the standardized T2DM mortality rate attributed to insufficient whole grain intake in China was 3.13/100 000, and the attributable mortality was 3.21/100 000 in men and 3.05/100 000 in women. The standardized attributable mortality rate was highest in southwestern China (3.97/100 000) and lowest in northern China (1.78/100 000). From 2005 to 2018, the standardized attributable mortality rate increased by 11.5% in men and decreased by 8.1% in women. The standardized attributable mortality rate in southwestern, southern and central China increased by 23.7%, 21.3% and 4.2%, respectively. The standardized attributable mortality rate in northern, northwestern, eastern and northeastern China decreased by 20.9%, 11.0%, 4.5% and 3.9%, respectively. Conclusion: The whole grain intake level of Chinese residents was low, and the whole grain intake of residents in all seven regions should be increased, especially in the southwest, and men should have more whole grain intake than women to reduce the death risk in patients with T2DM.

ABSTRACT

Objective: To describe the prevalence of alcohol consumption and the burden of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption in adults aged ≥20 years in 31 provinces in China from 2005 to 2018. Methods: Data from several national representative surveys was used to estimate provincial alcohol exposure level of adults aged ≥20 years from 2005 to 2018 by using kriging interpolation and locally weighted regression methods. Global disease burden research method and data, and China's death cause surveillance data were used to calculate the population attributable fraction (PAF) of hemorrhagic stroke and hypertensive heart disease and the deaths due to alcohol consumption in men and women aged ≥20 years in 31 provinces in China. China census data of 2010 were used to calculate the attributable standardized mortality rate. Results: In 2005 and 2018, the prevalence of alcohol consumption was 58.7% (95%CI: 57.8%-59.5%) and 58.4% (95%CI: 57.6%-59.3%), respectively, in men and 17.0% (95%CI: 16.6%-17.4%) and 18.7% (95%CI:18.1%-19.3%), respectively, in women. The daily alcohol intake was 24.6 (95%CI: 23.8-25.3) g and 27.7 (95%CI: 26.8-28.7) g, respectively, in men and 6.3 (95%CI: 6.0-6.5) g and 5.3 (95%CI: 5.0-5.6) g, respectively, in women. Alcohol exposure level was higher in the provinces in central and eastern China than in western provinces. The lowest exposure level was found in northwestern provinces. From 2005 to 2018, the PAF of hemorrhagic stroke death due to alcohol consumption increased from 5.5% to 6.8%, the attributable deaths increased from 50 200 to 59 100, while the PAF of hypertensive heart disease death due to alcohol consumption increased from 7.0% to 7.7%, the attributable deaths increased from 15 200 to 29 300. The PAF of hypertensive heart disease and hemorrhagic stroke was higher in men than in women, and in central and eastern provinces than in western provinces. In 2018, the standardized mortality rates of hemorrhagic stroke and hypertensive heart disease attributed to alcohol consumption were 4.58/100 000 and 2.11/100 000, respectively. Conclusions: The prevalence of alcohol consumption in men and daily alcohol intake of drinkers were relatively high in China, especially in eastern provinces. Alcohol exposure level was lower in women than in men. Regional measures should be taken to reduce the alcohol intakes in men and current drinkers in order to reduce the health problems caused by alcohol consumption.

ABSTRACT

OBJECTIVE To analyze the odor composition changes of two kinds of traditional Chinese medicine sachet (children type and adults type) with different placement time by using ultra-fast gasphase electronic nose technology. METHODS The change rule of sachet components at different storage times was analyzed by gas chromatography. At the same time, the qualitative results were obtained by combining electronic nose with Arochembase database. Discriminant factor analysis was used to analyze the overall odor composition differences of the two sachet samples. RESULTS A total of 10 odor compositions were identified in children-type sachet, including α-pinene and β-pinene as the functional index compositions; five odor compositions of children-type sachet disappeared after 0.25 days, and most of them disappeared after 7 days; the cumulative contribution rate of discriminant factor analysis was 99.225%. A total of 8 odor compositions were identified in adult-type sachets, including α-pinene and α-phellandrene as the functional index compositions; four odor components disappeared after the adult-type sachet was placed for 0.25 days; after 15 days of placement, the peak 6-8 disappeared, and the intensity of peak 5 decreased by 34.3% compared with 0 day of placement; the cumulative contribution rate of discriminant factor analysis was 91.965%. CONCLUSIONS With the extension of storage time, the smell and composition of the two traditional Chinese medicine sachets are decreasing. It is recommended that the use time of children-type sachet is 7 days, and that of adult-type sachet is 15 days.

ABSTRACT

Objective:To compare the influence of single and staged percutaneous coronary intervention (PCI) on long-term prognosis in patients with multi-vessel coronary artery disease.Methods:Using prospective research methods, 1 832 patients with multi-vessel coronary artery disease from January to December 2013 in Fuwai Hospital, Chinese Academy of Medical Sciences were selected. According to the time of PCI, the patients were divided into single PCI group (1 218 cases) and staged PCI group (614 cases). The patients were followed up for 2 years, the primary endpoint was major cardiovascular and cerebrovascular event (MACCE), including target vessel-related myocardial infarction (TV-MI), target vessel-related revascularization (TVR), cardiogenic death and stroke, and the secondary endpoint was stent thrombosis. The propensity score matching (PSM) was applied to balance the discrepancies between 2 groups, and the baseline and follow-up data were compared. The Kaplan-Meier survival curves were drawn to evaluate the survival rates events; multifactor Cox proportional risk regression was used to analyze whether staged PCI was an independent risk factor for the endpoint events.Results:The in-hospital stay, duration of procedure and synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score in single PCI group were significantly lower than those in staged PCI group: (5.54±3.09) d vs. (9.50±4.06) d, (43.12±28.55) min vs. (79.54±44.35) min, (14.04±7.63) scores vs. (18.51±7.79) scores, and there were statistical differences ( P<0.01); there were no statistical difference in complete revascularization rate and SYNTAX score after PCI between 2 groups ( P>0.05). Based on 2-year follow-up, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.5% (6/1 218) and 2.0% (12/614) vs. 0.4% (5/1 218), and there were statistical differences ( P<0.01). Kaplan-Meier survival curves analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were better than those in staged PCI group (99.5% vs. 97.9% and 99.6% vs. 98.0%, P<0.01). Multifactor Cox proportional risk regression analysis results showed that staged PCI was an independent risk factor for stent thrombosis ( HR = 3.91, 95% CI 1.25 to 12.18, P = 0.019). After PSM, the incidences of TV-MI and stent thrombosis in staged PCI group were significantly higher than those in single PCI group: 2.1% (13/614) vs. 0.7% (4/614) and 2.0% (12/614) vs. 0.5% (3/614), and there were statistical differences ( P<0.05); Kaplan-Meier survival curve analysis results showed that the event-free survival rates of TV-MI and stent thrombosis in single PCI group were significantly higher than those in staged PCI group: (99.3% vs. 97.9% and 99.5% vs. 98.0%, P<0.05); multifactor Cox proportional risk regression analysis results showed that staged PCI was not an independent risk factor of stent thrombosis ( HR = 2.29, 95% CI 0.58 to 9.00, P = 0.234). Both before and after PSM, there were no evidences for interaction between the type of angina pectoris and staged PCI ( P>0.05). Conclusions:Although a seemingly increase exists in the incidence of TV-MI and stent thrombosis in the staged PCI group, staged PCI is an independent risk factor neither for MACCE and its components, nor for stent thrombosis. In addition single PCI reduces the in-hospital days and duration of PCI procedure, which may be a relatively reasonable approach to clinical practice.

ABSTRACT

Objective:To explore the value of tumor stroma ratio (TSR) in non-small lung cancer (NSCLC) tissue in predicting the efficacy of tumor immunotherapy.Methods:The clinical and histopathological data of patients with stage ⅢB-Ⅳ NSCLC treated with immune checkpoint inhibitors in the Renmin Hospital of Wuhan University from January 2017 to December 2020 were collected. Taking 50% as the TSR boundary value, the patients were divided into low TSR group (≤50%) and high TSR group (>50%) . The histopathological features, 4-cycle objective response rate (ORR) and disease control rate (DCR) , 6-cycle ORR and DCR, and progression-free survival (PFS) were compared between the two groups. Univariate and multivariate Cox regression models were used to analyze the prognostic factors related to PFS.Results:A total of 50 patients were included, including 27 with low TSR and 23 with high TSR. There were no significant differences between the two groups in age ( χ2=0.59, P=0.441) , gender ( P=0.578) , smoking history ( χ2=0.12, P=0.730) , histopathological type ( χ2=2.33, P=0.313) , TNM stage ( χ2=0.22, P=0.636) , 4-cycle ORR ( χ2=0.48, P=0.487) and DCR ( P=0.593) , 6-cycle ORR ( χ2=0.05, P=0.818) and DCR ( P=0.641) . The incidence of brain metastasis was higher in the high TSR group than that in the low TSR group [34.8% (8/23) vs. 7.4% (2/27) , χ2=4.23, P=0.040]. Kaplan-Meier survival analysis showed that the PFS in the low TSR group was significantly longer than that in the high TSR group (15.6 months vs. 10.2 months, χ2=13.84, P<0.001) . Univariate analysis showed that TSR value ( HR=0.29, 95% CI: 0.14-0.58, P<0.001) and brain metastasis ( HR=2.38, 95% CI: 1.12-5.05, P=0.024) were correlated with the worse prognosis of NSCLC patients. Multivariate Cox regression analysis showed that TSR value was an independent prognostic factor for NSCLC immunotherapy ( HR=0.32, 95% CI: 0.14-0.70, P=0.004) . Conclusion:TSR is an independent predictor of immunotherapy for NSCLC, but whether it can predict the short-term efficacy of immunotherapy for advanced NSCLC still needs further research.

ABSTRACT

The purpose of this study was to investigate how Zuogui pills from the Kidney-tonifying and Nourishing Yin formula, in combination with the gonadotrophin-releasing hormone antagonist cetrorelix, affected the ovarian local oxidative stress response in decreasing ovarian reserve (DOR) mice. All animal experiments were carried out in accordance with the guidelines and standards established by Jinan University's Experimental Animal Management Committee. Cyclophosphamide (CTX)-treated DOR mice were given Zuogui pills, cetrorelix, or a combination of the two drugs intragastrically. After treatment, there were changes in the estrous cycle, serum sex hormone levels, oxidative stress-related indexes, growth biochemical factor levels, and SIRT1/P53/P21 expression. In comparison to the model group, the Zuogui pills and the cetrorelix+Zuogui pills group had significantly prolonged estrous periods and shortened interestrous periods, and the cetrorelix+Zuogui pills group had a significantly shortened cycle length. Follicle-stimulating hormone (FSH) decreased and estradiol (E2) increased in all treatment groups compared to the model group, oxidative stress indexes nitric oxide synthase (NOS), nitric oxide (NO), and reactive oxygen species (ROS) decreased, growth biochemical factors brain derived neurotrophic factor (BDNF) and growth differentiation factor 9 (GDF-9) concentrations increased significantly, and leukemia inhibitory factor (LIF) showed no significant change. SIRT1/P53/P21 immunohistochemical results revealed that, when compared to the model group, the expression of SIRT1 increased while the expression of P53 and P21 proteins decreased in all treatment groups, with the cetrorelix+Zuogui pills group having the largest decrease, with significant differences in all indicators. We conclude that cetrorelix combined with Zuogui pills for kidney nourishing and Yin recipe improved the oxidative stress response in the follicle by regulating the SIRT1/P53/P21 pathway, reducing peroxide product production, protecting ovarian function, and regulating ovarian hormone secretion, and its efficacy is superior to that of cetrorelix or Zuogui pills alone.

ABSTRACT

Objective: To explore and compare the effect of standard or prolonged dual antiplatelet therapy (DAPT) on the long-term prognosis of elderly patients with coronary heart disease complicated with diabetes mellitus after drug-eluting stent (DES) implantation. Methods: Consecutive patients with diabetes mellitus, ≥65 years old, underwent DES implantation, and had no adverse events within 1 year after operation underwent percutaneous coronary intervention (PCI) from January to December 2013 in Fuwai Hospital were enrolled in this prospective cohort study. These patients were divided into three groups according to DAPT duration: standard DAPT duration group (11 ≤ DAPT duration≤ 13 months) and prolonged DAPT duration group (13<DAPT duration≤ 24 months; DAPT duration>24 months). All the patients were followed up at 1, 6 months, 1, 2 and 5 years in order to collect the incidence of major adverse cardiovascular and cerebrovascular events (MACCE), and type 2 to 5 bleeding events defined by the Federation of Bleeding Academic Research (BARC). MACCE were consisted of all cause death, myocardial infarction, target vessel revascularization or stroke. The incidence of clinical adverse events were compared among 3 different DAPT duration groups, and Cox regression model were used to analyze the effect of different DAPT duration on 5-year long-term prognosis. Results: A total of 1 562 patients were enrolled, aged (70.8±4.5) years, with 398 female (25.5%). There were 467 cases in standard DAPT duration group, 684 cases in 13<DAPT duration≤ 24 months group and 411 cases in DAPT duration>24 months group. The patients in standard DAPT duration group and the prolonged DAPT duration groups accounted for 29.9% (467/1 562) and 70.1% (1 095/1 562), respectively. The 5-year follow-up results showed that the incidence of all-cause death in 13<DAPT duration≤ 24 months group (4.8%(33/684) vs. 8.6%(40/467),P=0.011) and DAPT duration>24 month group(4.1%(17/411) vs. 8.6%(40/467),P=0.008) were significantly lower than in standard DAPT group. The incidence of myocardial infarction in 13<DAPT duration≤ 24 months group was lower than in standard DAPT duration group (1.9%(13/684) vs. 5.1%(24/467),P=0.002). The incidence of MACCE in 13<DAPT duration≤ 24 months group was the lowest (standard DAPT duration group, 13<DAPT duration≤ 24 months group and DAPT duration>24 month group were 19.3% (90/467), 12.3% (84/684), 20.2% (83/411), respectively, P<0.001). There was no significant difference in the incidence of stroke and bleeding events among the three groups (all P>0.05). Multivariate Cox analysis showed that compared with the standard DAPT group, prolonged DAPT to 13-24 months was negatively correlated with MACCE (HR=0.601, 95%CI 0.446-0.811, P=0.001), all-cause death (HR=0.568, 95%CI 0.357-0.903, P=0.017) and myocardial infarction (HR=0.353, 95%CI 0.179-0.695, P=0.003). DAPT>24 months was negatively correlated with all-cause death (HR=0.687, 95%CI 0.516-0.913, P=0.010) and positively correlated with revascularization (HR=1.404, 95%CI 1.116-1.765, P=0.004). There was no correlation between prolonged DAPT and bleeding events. Conclusions: For elderly patients with coronary heart disease complicated with diabetes mellitus underwent DES implantation, and had no MACCE and bleeding events within 1 year after operation, appropriately prolonging of the DAPT duration is related to the reduction of the risk of cardiovascular adverse events. Patients may benefit the most from the DAPT between 13 to 24 months. In addition, prolonging DAPT duration does not increase the incidence of bleeding events in this patient cohort.

ABSTRACT

The terpenoids in Pogostemon cablin have complex structures and abundant pharmacological effects. Patchouli alcohol(PA) and pogostone(PO) have a high medicinal value by virtue of anti-tumor, anti-inflammatory, antibacterial, antioxidant, and other biological activities. Due to the low content of terpenoid metabolites in P. cablin, the study of biosynthesis and metabolism regulation can provide a biosynthetic basis for obtaining high-content terpenoids. In this study, key enzyme genes in biosynthesis, transcription factors in metabolism regulation, spatio-temporal expression of terpene synthase were reviewed, aiming to provide a reference for the development, protection, and utilization of P. cablin resources.

ABSTRACT

Tumor cells and tumor microenvironment (TME) are closely related. It is known that many factors will change the TME, then affect tumor development, however the change of TME is also inseparable from tumor cells. More and more studies have confirmed that the regulation of TME is the key to anti-tumor therapy. Therefore, it is critical to understand the effect of tumor cells on TME.
