ABSTRACT

The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often co-morbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.

ABSTRACT

Modern medicine has made remarkable achievements in safeguarding people's life and health, however, it is increasingly found that in the face of complex diseases, selective targeting of single target is often difficult to produce a comprehensive rehabilitation effect, and is prone to induce drug resistance, toxic side effects. Traditional Chinese medicine (TCM) has a long history of clinical application, and its clinical value in the treatment of complex diseases such as cardiovascular and cerebrovascular diseases, digestive diseases, skin diseases, rheumatism and immunity diseases, and adjuvant treatment of tumors has been proven to have obvious advantages. However, its modern research is relatively lagging behind, and in the face of the aging society and the characteristics of the modern disease spectrum, the traditional knowledge-driven research paradigm seems to be stuck in a bottleneck and difficult to make greater breakthroughs. Focusing on the key issues of TCM development in the new era, the clinical value-oriented strategy becomes to be a new research paradigm of TCM inheritance and innovation development, and dominant diseases would be the focus of the TCM inheritance and innovation development, which has been highly valued in recent years by the TCM academia and the relevant national management departments. Based on the clinical value, a series of policies are formulated for the selection and evaluation of the TCM dominant diseases (TCMDD), and exploratory researches about the clinical efficacy characteristics, the modern scientific connotation interpretation were carried out. The clinical value-oriented research paradigm of TCMDD inheritance and innovation development has been initially formed, which is characterized by strong policy support as the guarantee, systematic and standardized selection and evaluation methods as the driving force, scientific and effective research on internal mechanisms as the expansion, and effective clinical guidelines and principles as the transformation, which is of great value in promoting the high-quality development of the industries and undertaking of TCM. In this paper, the main policy support, selection and evaluation methods, therapeutic effect characterization, and modern scientific connotation research strategies of TCMDD in recent years have been comprehensively sorted out, with a view to providing the healthy and benign development of the research on TCMDD.

ABSTRACT

Ischemic stroke (IS) is a severe cerebrovascular disease with a high incidence, mortality, and disability rate. The first-line treatment for IS is the use of recombinant tissue plasminogen activator (r-tPA). Regrettably, numerous patients encounter delays in treatment due to the narrow therapeutic window and the associated risk of hemorrhage. Traditional Chinese medicine (TCM) has exhibited distinct advantages in preventing and treating IS. TCM enhances cerebral microcirculation, alleviates neurological disorders, regulates energy metabolism, mitigates inflammation, reduces oxidative stress injuries, and inhibits apoptosis, thereby mitigating brain damage and preventing IS recurrence. This article summarizes the etiology, pathogenesis, therapeutic strategies, and relationship with modern biology of IS from the perspective of TCM, describes the advantages of TCM in the treatment of IS, and further reviews the pharmacodynamic characteristics and advantages of TCM in the acute and recovery phases of IS as well as in post-stroke complications. Additionally, it offers valuable insights and references for the clinical application of TCM in IS prevention and treatment, as well as for the development of novel drugs.

ABSTRACT

Body mass index (BMI) has been increasing globally in recent decades. Previous studies reported that BMI was associated with sex hormone levels, but the results were generated via linear regression or logistic regression, which would lose part of information. Quantile regression analysis can maximize the use of variable information. Our study compared the associations among different regression models. The participants were recruited from the Center of Reproductive Medicine, The First Hospital of Jilin University (Changchun, China) between June 2018 and June 2019. We used linear, logistic, and quantile regression models to calculate the associations between sex hormone levels and BMI. In total, 448 men were included in this study. The average BMI was 25.7 (standard deviation [s.d.]: 3.7) kg m-2; 29.7% (n = 133) of the participants were normal weight, 45.3% (n = 203) of the participants were overweight, and 23.4% (n = 105) of the participants were obese. The levels of testosterone and estradiol significantly differed among BMI groups (all P < 0.05). In linear regression and logistic regression, BMI was associated with testosterone and estradiol levels (both P < 0.05). In quantile regression, BMI was negatively associated with testosterone levels in all quantiles after adjustment for age (all P < 0.05). BMI was positively associated with estradiol levels in most quantiles (≤80th) after adjustment for age (all P < 0.05). Our study suggested that BMI was one of the influencing factors of testosterone and estradiol. Of note, the quantile regression showed that BMI was associated with estradiol only up to the 80th percentile of estradiol.

ABSTRACT

Radiation-induced intestinal injury(RIII), a common complication of radiotherapy for pelvic malignancies, affects the quality of life and the radiotherapy efficacy for cancer. Currently, the main clinical approaches for the prevention and treatment of RIII include drug therapy, hyperbaric oxygen therapy, and surgical treatment. Among these methods, drug therapy is cost-effective. Traditional Chinese medicine(TCM) containing a variety of active components demonstrates mild side effects and good efficacy in preventing and treating RIII. Studies have proven that TCM active components, such as flavonoids, terpenoids, phenylpropanoids, and alkaloids, can protect the intestine against RIII by inhibiting oxidative stress, regulating the expression of inflammatory cytokines, modulating the mitochondrial apoptosis pathway, adjusting intestinal flora, and suppressing cell apoptosis. These mechanisms can help alleviate the symptoms of RIII. The paper aims to provide a theoretical reference for the discovery of new drugs for the prevention and treatment of RIII by reviewing the literature on TCM active components in the last 10 years.

ABSTRACT

Objective: To analyze the clinicopathological features and gene mutations of primary gastrointestinal stromal tumors (GISTs) of the stomach and intestine and the prognosis of intermediate- and high-risk GISTs. Methods: This was a retrospective cohort study. Data of patients with GISTs admitted to Tianjin Medical University Cancer Institute and Hospital from January 2011 to December 2019 were collected retrospectively. Patients with primary gastric or intestinal disease who had undergone endoscopic or surgical resection of the primary lesion and were confirmed pathologically as GIST were included. Patients treated with targeted therapy preoperatively were excluded. The above criteria were met by 1061 patients with primary GISTs, 794 of whom had gastric GISTs and 267 intestinal GISTs. Genetic testing had been performed in 360 of these patients since implementation of Sanger sequencing in our hospital in October 2014. Gene mutations in KIT exons 9, 11, 13, and 17 and PDGFRA exons 12 and 18 were detected by Sanger sequencing. The factors investigated in this study included: (1) clinicopathological data, such as sex, age, primary tumor location, maximum tumor diameter, histological type, mitotic index (/5 mm2), and risk classification; (2) gene mutation; (3) follow-up, survival, and postoperative treatment; and (4) prognostic factors of progression-free survival (PFS) and overall survival (OS) for intermediate- and high-risk GIST. Results: (1) Clinicopathological features: The median ages of patients with primary gastric and intestinal GIST were 61 (8-85) years and 60 (26-80) years, respectively; The median maximum tumor diameters were 4.0 (0.3-32.0) cm and 6.0 (0.3-35.0) cm, respectively; The median mitotic indexes were 3 (0-113)/5 mm² and 3 (0-50)/5 mm², respectively; The median Ki-67 proliferation indexes were 5% (1%-80%) and 5% (1%-50%), respectively. The rates of positivity for CD117, DOG-1, and CD34 were 99.7% (792/794), 99.9% (731/732), 95.6% (753/788), and 100.0% (267/267), 100.0% (238/238), 61.5% (163/265), respectively. There were higher proportions of male patients (χ²=6.390, P=0.011), tumors of maximum diameter > 5.0 cm (χ²=33.593, P<0.001), high-risk (χ²=94.957, P<0.001), and CD34-negativity (χ²=203.138, P<0.001) among patients with intestinal GISTs than among those with gastric GISTs. (2) Gene mutations: Gene mutations were investigated in 286/360 patients (79.4%) with primary gastric GISTs and 74/360 (20.6%) with primary intestinal GISTs. Among the 286 patients with gastric primary GISTs, 79.4% (227/286), 8.4% (24/286), and 12.2% (35/286), had KIT mutations, PDGFRA mutations, and wild-type, respectively. Among the 74 patients with primary intestinal GISTs, 85.1% (63/74) had KIT mutations and 14.9% (11/74) were wild-type. The PDGFRA mutation rate was lower in patients with intestinal GISTs than in those with gastric GISTs[ 0% vs. 8.4%(24/286), χ²=6.770, P=0.034], whereas KIT exon 9 mutations occurred more often in those with intestinal GISTs [22.2% (14/63) vs. 1.8% (4/227), P<0.001]. There were no significant differences between gastric and intestinal GISTs in the rates of KIT exon 11 mutation type and KIT exon 11 deletion mutation type (both P>0.05). (3) Follow-up, survival, and postoperative treatment: After excluding 228 patients with synchronous and metachronous other malignant tumors, the remaining 833 patients were followed up for 6-124 (median 53) months with a follow-up rate of 88.6% (738/833). None of the patients with very low or low-risk gastric (n=239) or intestinal GISTs (n=56) had received targeted therapy postoperatively. Among 179 patients with moderate-risk GISTs, postoperative targeted therapy had been administered to 88/155 with gastric and 11/24 with intestinal GISTs. Among 264 patients with high-risk GISTs, postoperative targeted therapy had been administered to 106/153 with gastric and 62/111 with intestinal GISTs. The 3-, 5-, and 10-year PFS of patients with gastric or intestinal GISTs were 96.5%, 93.8%, and 87.6% and 85.7%, 80.1% and 63.3%, respectively (P<0.001). The 3-, 5-, and 10-year OS were 99.2%, 98.8%, 97.5% and 94.8%, 92.1%, 85.0%, respectively (P<0.001). (4) Analysis of predictors of intermediate- and high-risk GISTs: The 5-year PFS of patients with gastric and intestinal GISTs were 89.5% and 73.2%, respectively (P<0.001); The 5-year OS were 97.9% and 89.3%, respectively (P<0.001). Multivariate analysis showed that high risk (HR=2.918, 95%CI: 1.076-7.911, P=0.035) and Ki-67 proliferation index > 5% (HR=2.778, 95%CI: 1.389-5.558, P=0.004) were independent risk factors for PFS in patients with intermediate- and high-risk GISTs (both P<0.05). Intestinal GISTs (HR=3.485, 95%CI: 1.407-8.634, P=0.007) and high risk (HR=3.753,95%CI:1.079-13.056, P=0.038) were independent risk factors for OS in patients with intermediate- and high-risk GISTs (both P<0.05). Postoperative targeted therapy was independent protective factor for PFS and OS (HR=0.103, 95%CI: 0.049-0.213, P<0.001; HR=0.210, 95%CI:0.078-0.564,P=0.002). Conclusions: Primary intestinal GIST behaves more aggressively than gastric GISTs and more frequently progress after surgery. Moreover, CD34 negativity and KIT exon 9 mutations occur more frequently in patients with intestinal GISTs than in those with gastric GISTs.

ABSTRACT

Objective: To study the construction of a prognostic model for hepatocellular carcinoma (HCC) based on pyroptosis-related genes (PRGs). Methods: HCC patient datasets were obtained from the Cancer Genome Atlas (TCGA) database, and a prognostic model was constructed by applying univariate Cox and least absolute shrinkages and selection operator (LASSO) regression analysis. According to the median risk score, HCC patients in the TCGA dataset were divided into high-risk and low-risk groups. Kaplan-Meier survival analysis, receiver operating characteristic (ROC) curves, univariate and multivariate Cox analysis, and nomograms were used to evaluate the predictive ability of the prognostic models. Functional enrichment analysis and immune infiltration analysis were performed on differentially expressed genes between the two groups. Finally, two HCC datasets (GSE76427 and GSE54236) from the Gene Expression Omnibus database were used to externally validate the prognostic value of the model. Univariate and multivariate Cox regression analysis or Wilcoxon tests were performed on the data. Results: A total of 366 HCC patients were included after screening the HCC patient dataset obtained from the TCGA database. A prognostic model related to HCC was established using univariate Cox regression analysis, LASSO regression analysis, and seven genes (CASP8, GPX4, GSDME, NLRC4, NLRP6, NOD2, and SCAF11). 366 cases were evenly divided into high-risk and low-risk groups based on the median risk score. Kaplan-Meier survival analysis showed that there were statistically significant differences in the survival time between patients in the high-risk and low-risk groups in the TCGA, GSE76427, and GSE54236 datasets (median overall survival time was 1 149 d vs. 2 131 d, 4.8 years vs. 6.3 years, and 20 months vs. 28 months, with P = 0.000 8, 0.034 0, and 0.0018, respectively). ROC curves showed good survival predictive value in both the TCGA dataset and two externally validated datasets. The areas under the ROC curves of 1, 2, and 3 years were 0.719, 0.65, and 0.657, respectively. Multivariate Cox regression analysis showed that the risk score of the prognostic model was an independent predictor of overall survival time in HCC patients. The risk model score accurately predicted the survival probability of HCC patients according to the established nomogram. Functional enrichment analysis and immune infiltration analysis showed that the immune status of the high-risk group was significantly decreased. Conclusion: The prognostic model constructed in this study based on seven PRGs accurately predicts the prognosis of HCC patients.

ABSTRACT

Objective: To analyze the genetic characteristics of varicella-zoster virus (VZV) in people aged 20 years and under in Yichang City of Hubei Province from 2019 to 2020. Methods: Based on the Yichang Health Big Data Platform, we investigated cases 20 and under clinically diagnosed as herpes zoster in three hospitals from March 2019 to September 2020. Collecting vesicle fluid and throat swab samples of the cases and completing questionnaires to obtain basic information. Real-time fluorescent quantitative PCR was used for positive identification of the virus. PCR amplification of VZV's open reading frame (ORF) and sequencing of the products to determine the VZV genotype. Analyze mutations at some specific single nucleotide polymorphism (SNP) sites. Results: Among 46 cases of herpes zoster, the male to female ratio was 1.3∶1 (26∶20) and the age ranged from 7 to 20 years old. Fifteen cases had been vaccinated against varicella, including 13 and 2 cases of 1 and 2 doses, respectively. VZV strains were detected in 34 samples (73.91%), all belonging to Clade 2. Phylogenetic tree analysis of the nucleotide of ORF22 showed, compared with Clade 2 referenced strains, the sequence matching degree of nucleotide for all 34 samples was 99.0% to 100.0%. Conclusion: The main VZV strain causing herpes zoster in people aged 20 years and under in Yichang from 2019 to 2020 was Clade 2.

ABSTRACT

Objective To compare the diagnostic performance of PI-RADS v2.1 and PI-RADS v2 in the detection of clinically significant prostate cancer(csPCa) by Meta-analysis. Methods The major biomedical databases were searched (CNKI, CBM, Medline, and Embase) with the keywords "PIRADS v2.1" or "PI-RADS v2.1". The Quality Assessment of Diagnostic Accuracy Studies Tool v2 (QUADAS-2) was used to evaluate literature quality. Meta-analysis was performed using STATA17.0 and ReMan5.4 software. Forest plots were used to represent the sensitivity and specificity of PI-RADS v2.1 and PI-RADS v2 for each study. Sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were combined, and diagnostic performance was evaluated using asummary receiver operating characteristic curve (SROC). Subgroup analysis was performed on three covariables: tumor location, threshold, and the nationality of authors. Results A total of 12 studies were included, involving 3 158 patients and 3 243 lesions. Forall zones and the whole gland, PI-RADS v2.1 had a larger area under the SROC curve (AUC) for csPCa performance, compared with PI-RADS v2. Subgroup analysis: PI-RADS v2.1 also had a larger area under the SROC (AUC) to detect transitional zone csPCa. Different diagnostic thresholds: when a score of 4 was used for the threshold, PI-RADS v2.1 had the maximum area under SROC (AUC) for csPCa performance detection. Author nationality: Researches of PI-RADS v2.1 in Chinese authors had the largest area under the SROC (AUC) in detecting csPCa performance. Conclusion Compared with PI-RADS v2, the diagnostic performance of PI-RADS v2.1 in detecting csPCa is not obviously improved and overall specificity is still low.

ABSTRACT

Objective:To investigate the disability status of patients with inflammatory bowel disease (IBD) in China and to identify the influencing factors of the inflammatory bowel disease disability index (IBD-DI).Methods:From October 1 to December 31, 2021, a total of 1 170 IBD patients were recruited from 7 IBD centers and WeChat public platforms in China. All the patients were surveyed by the IBD-DI questionnaire, which included demographic information, disease activity, medication history, treatment and surgical history. Demographic information included gender, age, income status, etc. Multiple linear regression was used to analyze the influencing factors of IBD-DI.Results:Among the 1 170 IBD patients, 746 patients (63.76%) were male and 424 patients (36.24%) were female; there were 871 cases (74.44%) of Crohn′s disease(CD), 277 cases (23.68%) of ulcerative colitis (UC) and 22 cases (1.88%) of inflammatory bowel disease undassified (IBDU). The age was 36.00 years old (29.00 years old, 45.00 years old), and the IBD-DI score was 9.00 (5.00, 15.00). The results of multiple linear regression analysis revealed that the disease activity ( β=0.65, t=22.33, P<0.001), current treatment with enteral nutrition ( β=0.09, t=3.06, P<0.001), and history of perianal surgery ( β=0.06, t=2.12, P=0.034) were influencing factors of IBD-DI in the CD patients. Disease activity ( β=0.65, t=14.37, P<0.001), household per capita annual income ( β=-0.16, t=-3.59, P<0.001), current usage of immunosuppressants ( β=0.12, t=2.66, P=0.008), current treatment with enteral nutrition ( β=0.12, t=2.57, P=0.011), and the duration of each exercise ( β=-0.12, t=-2.67, P=0.008) were influencing factors of IBD-DI in UC patients. Conclusions:Disability is common in Chinese IBD patients, and their IBD-DI were different. Disease activity is the most important factor affecting IBD-DI. The IBD-DI is higher in IBD patients receiving enteral nutrition treatment, CD patients with a history of perianal surgery and UC patients with current usage of immunosuppressants. However, household per capita annual income and the duration of each exercise are negatively correlated with IBD-DI in UC patients.

ABSTRACT

Objective:To investigate the efficacy of work-amusement activities combined with daytime rehabilitation technology for schizophrenia in remission.Methods:A total of 218 patients with schizophrenia in remission who received treatment in Shaoxing 7 th People's Hospital from September 2018 to April 2020 were prospectively included in this study. They were randomly divided into an observation group ( n = 109) and a control group ( n = 109). Both groups were treated with routine drugs. Based on this, the control group was treated with daytime rehabilitation technology, and the observation group was treated with daytime rehabilitation technology combined with work-amusement activities. After 12 weeks of treatment, curative effect, Positive and Negative Symptom Scale (PANSS) and Montreal Cognitive Assessment (MoCA) scores were compared between the two groups. Results:After 12 weeks of treatment, total response rate in the observation group was significantly higher than that in the control group (91.74% vs. 77.06%, χ2 = 8.92, P < 0.05). After treatment, PANSS score in the observation group was significantly decreased compared with that before treatment [(33.12 ± 4.19) points vs. (40.54 ± 5.32) points, t = 11.44, P < 0.05). After treatment, PANSS score in the control group was significantly decreased compared with that before treatment [(35.02 ± 4.33) points vs. (40.54 ± 5.32) points, t = 8.55, P < 0.05). After treatment, PANSS score in the observation group was significantly lower than that in the control group ( t = 3.29, P < 0.05). After treatment, MoCA score in the observation group was significantly increased compared with that before treatment [(27.14 ± 2.89) points vs. (23.39 ± 2.48) points, t = 10.28, P < 0.05]. After treatment, MoCA score in the control group was significantly increased compared with that before treatment [(26.02 ± 2.73) points vs. (23.41 ± 2.56) points, t = 7.28, P < 0.05]. After treatment, MoCA score in the observation group was significantly higher than that in the control group ( t = 2.94, P < 0.05). Conclusion:The efficacy of work-amusement activities combined with daytime rehabilitation technology is marked on schizophrenia in remission, which can markedly improve mental symptoms and cognitive function.

ABSTRACT

Objective:To explore the application effect of case-based learning (CBL) combined with three-dimensional (3D) imaging technology in thoracic surgery probationary teaching.Methods:Ninety thoracic surgery interns in the Affiliated Hospital of Yangzhou University, China in 2019 were selected and divided into the conventional theoretical teaching group (group A), CBL group (group B), and CBL combined with 3D imaging technology group (group C) according to the random number table method. Group A was taught with conventional theory; group B was taught by CBL; in group C, 3D imaging software was used to reconstruct computed tomography data based on CBL. The theoretical scores of the three groups were evaluated respectively, and a questionnaire survey was conducted on the students (including whether the teaching is conducive to stimulating the interest and enthusiasm of learning, whether it is conducive to the establishment of clinical thinking, evaluation of advantages and disadvantages of the teaching method, and whether the teaching method is conducive to the mastery of theoretical knowledge). SPSS 20.0 was used for analysis of variance, t test, and Chi-square test. Results:The theoretical score of group A (85.83±4.62) was the lowest, and the theoretical score of group B was significantly lower than that of group C (89.71±5.84 vs. 94.60±6.28); the answer time of group C (286.68±77.56 seconds) was the shortest, and the answer time of group B was significantly shorter than that of group A (359.78±80.55 vs. 423.31±83.53 seconds, P<0.001). Group C was significantly better than group B and group A in the aspects of stimulating interest and enthusiasm in teaching, conducive to the establishment of clinical thinking, advantages of the teaching method, and conducive to the mastery of theoretical knowledge, and group B was significantly better than group A ( P<0.001). Conclusion:The combination of CBL and 3D reconstruction technology improves the recognition of thoracic surgery interns to the teaching method, increases their theoretical scores, stimulates their learning interest and enthusiasm, cultivates their clinical thinking, and enhances their mastery of theoretical knowledge.

Objective:To investigate the mechanism of depression between social capital and cognitive function of the elderly in nursing institutions, and provide new ideas for improving the cognitive function of the elderly.Methods:This study was a cross-sectional survey. Using the convenient sampling method to collect the general information questionnaire, the Geriatric Depression Scale (GDS), Social Capital Scale and Montreal Cognitive Assessment Scale (MoCA) of 218 elderly people from three elderly nursing institutions including Shenyang Health Care Centre, Songpu Nursing Home and Colourful Sunshine City Pension Service Centre in Shenyang from July 2020 to January 2021.Results:A total of 218 questionnaires were distributed and 202 valid questionnaires were recovered. The effective recovery rate was 92.7%. The scores of the cognitive function, depression and social capital of the elderly were (23.60 ± 4.25), (6.38 ± 4.35) and (75.41 ± 8.61). Depression scores were negatively correlated with social capital scores and cognitive function scores ( r = - 0.401, - 0.481, both P<0.05); there was a positive correlation between social capital scores with cognitive function scores ( r = 0.338, P<0.05). There was a mediating effect of depression between social capital and cognitive function, accounting for 42.1%. Conclusions:While improving the cognitive function of the elderly in nursing institutions by improving the level of social capital, it is necessary to pay attention to the mediatingeffect of depression, strengthen the psychological counseling of the elderly, promote mental health, and further reduce the occurrence and development of cognitive decline in the elderly.

ABSTRACT

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

ABSTRACT

This study screened excellent carriers for co-loading tanshinone Ⅱ_A(TSA) and astragaloside Ⅳ(As) to construct antitumor nano-drug delivery systems for TSA and As. TSA-As microemulsions(TSA-As-MEs) were prepared by water titration. TSA-As metal-organic framework(MOF) nano-delivery system was prepared by loading TSA and As in MOF by the hydrothermal method. Dynamic light scattering(DLS), transmission electron microscopy(TEM), and scanning electron microscopy(SEM) were used to characterize the physicochemical properties of the two preparations. Drug loading was determined by HPLC and the effects of the two preparations on the proliferation of vascular endothelial cells, T lymphocytes, and hepatocellular carcinoma cells were detected by the CCK-8 method. The results showed that the particle size, Zeta potential, and drug loading of TSA-As-MEs were(47.69±0.71) nm,(-14.70±0.49) mV, and(0.22±0.01)%, while those of TSA-As-MOF were(258.3±25.2) nm,(-42.30 ± 1.27) mV, and 15.35%±0.01%. TSA-As-MOF was superior to TSA-As-MEs in drug loading, which could inhibit the proliferation of bEnd.3 cells at a lower concentration and improve the proliferation ability of CTLL-2 cells significantly. Therefore, MOF was preferred as an excellent carrier for TSA and As co-loading.

ABSTRACT

Objective To observe the effect of excess oxygen supply for different time periods on the mitochondrial energy metabolism in alveolar epithelial type Ⅱ cells. Methods Rat RLE-6TN cells were assigned into a control group (21% O2 for 4 h) and excess oxygen supply groups (95% O2 for 1,2,3,and 4 h,res-pectively).The content of adenosine triphosphate (ATP),the activity of mitochondrial respiratory chain complex V,and the mitochondrial membrane potential were determined by luciferase assay,micro-assay,and fluorescent probe JC-1,respectively.Real-time fluorescence quantitative PCR was employed to determine the mRNA levels of NADH dehydrogenase subunit 1 (ND1),cytochrome b (Cytb),cytochrome C oxidase subunit I (COXI),and adenosine triphosphatase 6 (ATPase6) in the core subunits of mitochondrial respiratory chain complexes Ⅰ,Ⅲ,Ⅳ,and Ⅴ,respectively. Results Compared with the control group,excess oxygen supply for 1,2,3,and 4 h down-regulated the mRNA levels of ND1 (q=24.800,P<0.001;q=13.650,P<0.001;q=9.869,P<0.001;q=20.700,P<0.001),COXI (q=16.750,P<0.001;q=10.120,P<0.001;q=8.476,P<0.001;q=14.060,P<0.001),and ATPase6 (q=22.770,P<0.001;q=15.540,P<0.001;q=12.870,P<0.001;q=18.160,P<0.001).Moreover,excess oxygen supply for 1 h and 4 h decreased the ATPase activity (q=9.435,P<0.001;q=11.230,P<0.001) and ATP content (q=5.615,P=0.007;q=5.029,P=0.005).The excess oxygen supply for 2 h and 3 h did not cause significant changes in ATPase activity (q=0.156,P=0.914;q=3.197,P=0.116) and ATP content (q=0.859,P=0.557;q=1.273,P=0.652).There was no significant difference in mitochondrial membrane potential among the groups (F=0.303,P=0.869). Conclusion Short-term excess oxygen supply down-regulates the expression of the core subunits of mitochondrial respiratory chain complexes and reduces the activity of ATPase,leading to the energy metabolism disorder of alveolar epithelial type Ⅱ cells.

ABSTRACT

Diabetic retinopathy(DR), one of the common complications of diabetes, is a major cause of blindness. Traditionally, DR has been considered primarily a microvascular disease, and as research has progressed, it is now believed that disruption of the neuro-glia-vascular unit(NVU)and imbalance in its coupling mechanisms(coupling)play a key role in the early onset of DR. Understanding the cellular and molecular basis of NVU and how diabetes alters normal cellular communication and disrupts the cellular environment is important for the early prevention and treatment of DR. This paper summarizes the retinal NVU and its involvement in the molecular mechanism of DR pathogenesis, DR treatment based on retinal NVU repair, and discusses the future prospects and problems of DR.
