ABSTRACT

ObjectiveTo observe the possible mechanism of Xixin Decoction (洗心汤, XXD) in the prevention and treatment of Alzheimer 's disease(AD). MethodsFifty rapid aging model mice (SAMP8) were randomly divided into model group, probiotic group, high-, moderate- and low-dose group of XXD, with 10 mice in each group. Another 10 homologous anti-rapid aging mice (SAMR1) were set as control group. After 10 weeks of feeding, the control group and the model group were given 10 ml·kg-1·d-1 of distilled water by gavage, while the probiotic group (0.39 g·kg-1·d-1), the high-dose group of XXD (5.08 g·kg-1·d-1), the moderate-dose group of XXD (2.54 g·kg-1·d-1), and the low-dose group of XXD (1.27 g·kg-1·d-1) were given corresponding drugs or decoctions by gavage, once a day in all groups. After 10 weeks of intragastric administration, Morris water maze was used to detect the spatial learning and memory ability of mice in each group. HE staining was used to observe the pathological changes of hippocampal CA3 region and colon. The levels of β-amyloid 1-42 (Aβ1-42), lipopolysaccharide (LPS), serum amyloid A (SAA) and acetylcholine (ACH) in hippocampus and colon were detected by ELISA.The diversity of intestinal flora in mouse feces was detected by 16S rRNA sequencing. ResultsCompared to those in the control group, the levels of Aβ1-42,LPS, SAA increased, while the level of ACH decreased in the model group (P<0.05 or P<0.01). Compared to those in the model group, the escape latency period of the probiotic group was significantly shortened on the 2nd and 5th days, while the escape latency period was shortened, and the residence time in the target platform quadrant increased in the high-dose XXD group during the 2nd to 5th days; the escape latency period was shortened significantly in the moderate-dose XXD group on the 5th day (P<0.05 or P<0.01). Compared to those in the model group, the hippocampal neuron cells in the high- and moderate-dose XXD groups were arranged more closely, with decreased levels of SAA, Aβ1-42 and LPS, increased ACH level, Simpson and Shannon index (P<0.05 or P<0.01); the arrangement of hippocampal neuron cells in the probiotic group and the low-dose XXD group was relatively loose; the proportions of Bacteroidetes and Prevotella were significantly reduced in the probiotic group and the high-dose XXD group, while that of Firmicutes and Lactobacillus significantly increased (P<0.05 or P<0.01). Compared to those in the probiotic group and the high-dose XXD group, the number of goblet cells in the moderate-dose XXD group decreased, and the number of glands in the low-dose XXD group decreased with atrophy. The high-dose XXD group had decreased Aβ1-42 level in the hippocampus, increased ACH level in thehippocampus and colon tissue, and decreased SAA in the colon tissue than the moderate- and low-dose XXD groups (P<0.05 or P<0.01); moreover, the SAA level in the hippocampus was significantly higher in the low-dose XXD group than the high- and moderate-dose groups (P<0.01). ConclusionXXD can improve the spatial learning and memory ability of SAMP8, reduce the production and deposition of LPS, SAA and Aβ1-42 in brain and intestine, and increase the content of ACH. The mechanism of its prevention and treatment of AD maybe related to regulating intestinal microecology, affecting flora diversity and improving inflammatory response.

ABSTRACT

OBJECTIVE To investigate the efficacy and safety of aerosol inhalation of polycolistin B in the treatment of severe pneumonia combined with mechanical ventilation, and to provide a reference of real-world data for clinical drug therapy. METHODS A retrospective cohort study was conducted to analyze the clinical data of 87 patients with severe pneumonia combined with mechanical ventilation at the First Affiliated Hospital of Shandong First Medical University from January 2021 to February 2023. According to route of administration, all patients were divided into combined group (24 cases, receiving aerosol YXH2021ZX013) inhibition of polycolistin B combined with intravenous dripping) and routine group (63 cases, intravenous dripping of polycolistin B alone). The differences in efficacy (mortality,clinical response rate and bacterial clearance rate)and safety (elevated serum creatinine, bronchospasm and skin pigmentation) were compared between two groups; the influential factors of primary outcome index as mortality were analyzed through univariate analysis and multivariate Logistic regression analysis. RESULTS In terms of efficacy, there were no statistical differences in mortality(37.50% vs. 41.27%, P=0.749), clinical response rate (54.17% vs. 55.56%, P=0.907) and bacterial clearance rate (45.83% vs. 44.44%, P=0.907) between the two groups. In terms of safety, the incidence of bronchospasm in the combined group was significantly higher than that of the routine group (12.50% vs. 0, P=0.028), but the differences in incidence of elevated serum creatinine and skin pigmentation between two groups were not statistically significant (P>0.05). Univariate analysis showed that the moralities were higher in the case of infected with Acinetobacter baumannii, Klebsiella pneumoniae and combined use of quinolones (P<0.05); multivariate Logistic regression analysis showed that infection with A. baumannii (OR=3.36, P=0.014) and combined use of quinolones (OR=3.54, P=0.013) were independently associated with mortality (P<0.05). CONCLUSIONS For severe pneumonia patients with mechanical ventilation, intravenous dripping of polycolistin B combined with aerosol inhalation does not show superior efficacy compared with intravenous dipping of polycolistin B alone, but significantly increases the incidence of bronchospasm. Infection with A. baumannii and combined use of quinolones are independent risk factors for the increase of mortality.

ABSTRACT

Objective:To investigate the clinical efficacy of induced membrane technique in the staged treatment of adult chronic hematogenous osteomyelitis (CHOM) of long bone.Methods:The clinical data were retrospectively analyzed of the 22 adult patients with CHOM of long bone who had been admitted to the 920th Hospital, Joint Logistics Support Force of PLA from January 2016 to December 2019. There were 18 males and 4 females, aged from 16 to 56 years (average, 31.81 years). Their disease duration ranged from 0.6 to 42.0 years, averaging 18.4 years. By the Cierny-Mader anatomical classification, 4 cases were type Ⅰ, 6 cases Type Ⅲ, and 12 cases type Ⅳ. In the first stage, the bone defects were filled with antibiotic bone cement after thorough debridement. In the second stage when the infection had been controlled, the bone defects were repaired with bone grafts after removal of the bone cement. Bone healing time and complications were followed up. The treatment effects were evaluated by comparisons of the infection control indexes [including clinical manifestations like local redness, swelling, pus, and pain, and blood white blood cell count, C-Reactive protein (CRP), and erythrocyte sedimentation rate (ESR) as well] before the primary surgery, before the secondary surgery and at the last follow-up.Results:The volumes of the bone defects after stage-one debridement ranged from 54 cm 3 to 176 cm 3 (mean, 90.9 cm 3). All patients were followed up for 20 to 51 months (mean, 30.1 months) after surgery. All bone defects healed after 4 to 11 months (mean, 6.6 months). Postoperatively, infection developed at the bone extraction site of the posterior superior iliac spine in 3 cases and pain was observed at the donor site in one case, but the conditions were relieved after symptomatic treatment. Fracture and plate breakage occurred at the bone defect site in one case who had fallen down 7 months after operation, but responded to reoperation. The last follow-up revealed such symptoms as redness, swelling and pus discharge in none of the patients. The white blood cell count [(5.70 ± 1.57) × 10 9/L and (5.65 ± 1.58) × 10 9/L], CRP [(7.56 ± 2.57) mg/L and (7.25 ± 3.83) mg/L] and ESR [(9.64 ± 2.90) mm/h and (10.55 ± 5.23) mm/h] before the secondary surgery and at the last follow-up were significantly lower than those before the primary surgery [(8.24 ± 2.18) × 10 9/L, (49.54 ± 19.56) mg/L, and (42.68 ± 13.77) mm/h] (all P < 0.05). However, there were no significant differences between the indexes before the secondary surgery and at the last follow-up ( P > 0.05). Conclusion:In the staged treatment of adult CHOM of long bone, the induced membrane technique can effectively control infection, achieve repair of bone defects, and reduce complications.

ABSTRACT

Objective:To explore the value of blood lipids, serum interleukin-6 (IL-6) and thyroid-stimulating hormone (TSH) detection in patients with differentiated thyroid cancer.Methods:From Mar. 2016 to Oct. 2021, 120 cases of DTC were admitted to the DTC group, 138 patients with benign thyroid nodules were included in the benign group, and 100 healthy people undergoing the physical examination in our hospital during the same period. were enrolled in the control group. Triglyceride (TG) , total cholesterol (TC) , high density liptein cholesterol (HDL-C) , low density lipoprotein (LDL-C) , IL-6, and TSH were compared between groups, and statistically significant indexes were included for multivariate analysis of the occurrence of DTC. The sensitivity, specificity and optimal cut-off value were analyzed, and their relationship with the clinicopathological characteristics of DTC patients was analyzed.Results:Serum TSH and IL-6 levels from high to low were malignant group, benign group and control group, and HDL-C levels from high to low were control group, benign group and malignant group ( P<0.05) . There was no significant difference in the levels of TC, TG or LDL-C ( P>0.05) . Multivariate Llogistics regression analysis indicated that TSH and IL-6 may be risk factors for the occurrence of differentiated thyroid cancer (all OR>1, P<0.05) . HDL-C may be a protective factor for the occurrence of differentiated thyroid cancer ( OR<1, P<0.05) . The ROC curve was drawn to determine the optimal cut-off value of TSH for the diagnosis of differentiated thyroid cancer, AUC: 0.985, sensitivity was 93.25%, specificity was 96.34%, 95% CI: 0.949-1.000 ( P<0.001) ; the best cut-off value of IL-6 for the diagnosis of differentiated thyroid cancer was 48.96 ng/L, AUC: 0.980, sensitivity was 96.98%, the specificity was 91.53%, 95%CI: 0.956-1.000 ( P<0.05) ; the best cut-off value of HDL-C for the diagnosis of differentiated thyroid cancer was 1.441 mmol/L, AUC: 0.0.691, the sensitivity was 85.10%, the specificity was 48.06%, 95%CI: 0.563-0.812 ( P<0.05) . The serum levels of TSH and IL-6 in patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis, and the level of HDL-C was significantly lower than those in patients without lymph node metastasis ( P<0.05) . TNM staging The serum levels of TSH and IL-6 in patients with stage III and IV were significantly higher than those in patients with stage I and II, and HDL-C was significantly lower than that in patients with stage I and II ( P<0.05) . Conclusions:Serum IL-6, TSH and HDL-C are closely related to the occurrence of differentiated thyroid cancer. The detection of serum IL-6, TSH and HDL-C is helpful for the differentiation of benign and malignant thyroid nodules. The presence or absence of lymph node metastasis in patients with differentiated thyroid cancer is related to TNM staging, and the detection value is high.

ABSTRACT

Objective To explore the expression levels of YBX1 and FOXA1 in gastric cancer tissues and determine their relationship with prognosis. Methods A total of 131 patients with gastric cancer were studied, and the corresponding adjacent normal tissues of each patient were selected as the control. qRT-PCR and immunohistochemistry were used to detect the expression levels of YBX1 and FOXA1 in cancer tissues and adjacent tissues. The correlation between YBX1 and FOXA1 protein expression in gastric cancer tissues was expressed by Crammer's V coefficient, and the correlation between YBX1 mRNA and FOXA1 mRNA was analyzed by Pearson method. Kaplan-Meier method was used to analyze the relationship between YBX1, FOXA1 protein expression in gastric cancer tissues and the 5-year overall survival rate of patients. Univariate and multivariate Cox regression analyses were used to analyze the factors affecting the prognosis of patients with gastric cancer. Results Compared with paracancerous tissue, the levels of FOXA1 and YBX1 in cancer tissues were lower and higher, respectively (P < 0.05). A negative correlation was observed between YBX1 mRNA and FOXA1 mRNA in gastric cancer (r=-0.675, P < 0.05). The expression of YBX1 and FOXA1 proteins in gastric cancer tissues was negatively correlated (Crammer's V=-0.497, P < 0.001). The expression of YBX1 and FOXA1 proteins in gastric cancer tissue was related to the degree of differentiation, lymph node metastasis, and TNM staging (P < 0.05). The 5-year survival rate of the YBX1 negative expression group and the FOXA1 positive expression group were higher than those of the YBX1 positive expression group, and the FOXA1 negative expression group both P < 0.05). TNM staging and YBX1 were independent risk factors for death in patients with gastric cancer (P < 0.05), and FOXA1 was a protective factor (P < 0.05). Conclusion YBX1 is highly expressed and FOXA1 is lowly expressed in gastric cancer tissues; they are closely related to the disease progression and prognosis of patients with gastric cancer.

ABSTRACT

Objective: To analyze the efficacy of sinonasal adenoid cystic carcinoma (ACC) with perineural invasion (PNI), and explore the prognostic value of PNI on sinonasal adenoid cystic carcinoma. Methods: The clinical data of 105 patients with sinonasal ACC admitted to Cancer Hospital, Chinese Academy of Medical Sciences from January 2000 to December 2016 were retrospectively reviewed. All patients were restaged according to American Joint Committee on Cancer 8th edition. Follow-up visits were conducted to obtain information of treatment failure and survival outcome. The Log rank test was used for univariate analysis of prognostic factors, and Cox regression model was used for multivariate prognostic analysis. Results: The maxillary sinus (n=59) was the most common primary site, followed by the nasal cavity (n=38). There were 93 patients with stage Ⅲ-Ⅳ. The treatment modalities included surgery alone (n=14), radiotherapy alone (n=13), preoperative radiotherapy plus surgery (n=10), and surgery plus postoperative radiotherapy (n=68). The median follow-up time was 91.8 months, the 5-year local control (LC), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) rates were 72.6%, 73.0%, 52.9% and 78.0%, respectively. There were 33 patients (31.4%) with PNI-positive. The 5-year DMFS, PFS, and OS rates of PNI-positive group were 53.7%, 29.4% and 56.5%, respectively, which were significantly inferior to those of PNI-negative group (80.8%, 63.0% and 86.8%, respectively, P<0.05), while there was no significant difference in the 5-year LC rate between both groups (64.5% vs 76.5%, P=0.273). The multivariate Cox regression analysis showed PNI was one of the poor prognostic factors of DMFS (HR=3.514, 95%CI: 1.557-7.932), PFS (HR=2.562, 95%CI: 1.349-4.866) and OS (HR=2.605, 95%CI: 1.169-5.806). Among patients with PNI-positive, the 5-year LC, PFS and OS rates of patients received surgery combined with radiotherapy were 84.9%, 41.3% and 72.7%, respectively, which were significantly higher than 23.3%, 10.0% and 26.7% of patients receiving surgery or radiotherapy alone (P<0.05). Conclusion: The presence of PNI increases the risk of distant metastasis in patients with sinonasal ACC. Compared with patients with PNI-negative, the prognosis of patients with PNI-positive is relatively poor, and surgery combined with radiotherapy for PNI-positive sinonasal ACC results in good clinical outcomes.

ABSTRACT

Objective:To build a simple, rapid and accurate visual prediction model for identifying the ST-segment elevation myocardial infarction (STEMI) patients with high risk of no reflow during the primary percutaneous coronary intervention (PPCI).Methods:A retrospective study of STEMI patients treated by PPCI in China-Japan Friendship Hospital from January 2018 to June 2019 was performed. The clinical data including sex, age, comorbidities, personal history, Killip classification and laboratory examinations were collected. Whether the patients had no reflow during the PPCI were retrospective observed. Multivariable logistic regression analysis was used to identify risk factors. A nomogram was developed to predict no reflow risk among STEMI patients. C-index and Hosmer-Lemeshow goodness-of-fit test were used to verify the differentiation, consistency and clinical applicability of the model. Internal verification of the model was used by Bootstrap validation.Results:Of the included 280 patients, the prevalence of no flow rate was 30.7%. Killip class Ⅲ or Ⅳ ( OR=3.537, 95% CI: 1.665-7.514, P=0.002), mean platelet volume≥9 fL ( OR=4.003, 95% CI: 1.091-14.689, P=0.037), Glucose ≥7.8 mmol/L ( OR=2.315, 95% CI: 1.318-4.066, P=0.003) and time from symptoms to hospital ( OR=5.594, 95% CI: 2.041-15.328, P=0.002) were the independent risk factors of no flow (all P<0.05). The AUC of ROC curve in the prediction model was 0.731 (95% CI: 0.668-0.795). The calibration curves were close to the standard curve. Conclusions:The visual prediction model constructed in this study can early identify STEMI patients with high risk of no reflow, and may be helpful for physicians to provide prospective pre-treatment before the occurrence of no reflow during PPCI.

ABSTRACT

ObjectiveTo study the clinical efficacy of dapagliflozin combined with Shexiang Baoxinwan (SXBXW) in the treatment of acute heart failure with reduced ejection fraction (HFrEF) and syndrome of Qi deficiency and blood stasis. MethodA total of 176 patients hospitalized due to acute HFrEF (syndrome of Qi deficiency and blood stasis) were selected and randomized into control group, SXBXW group, dapagliflozin group, and SXBXW + dapagliflozin group (the latter three groups were called the intervention groups). The New York Heart Association (NYHA) class, 6-minute walk test (6MWT) score, Kansas City Cardiomyopathy Questionnaire (KCCQ) score, traditional Chinese medicine (TCM) syndrome score, N-terminal pro-brain natriuretic peptide (NT-proBNP), soluble suppression of tumorigenicity 2 (sST2), interleukin-6 (IL-6), and hypersensitive C-reactive protein (hs-CRP) of the patients were evaluated and measured at the time of admission, 1 week after treatment, and 2 weeks of treatment. Furthermore, the hospital stay, in-hospital mortality, and 30-day re-admission rate were recorded. Statistical analysis was performed to evaluate the efficacy of each group. ResultAfter 1 week of treatment, the SXBXW group exhibited superior NYHA class, KCCQ score, TCM syndrome score and curative effect, IL-6, and hs-CRP to the control group (P<0.05, P<0.01). After 2 weeks of treatment, the SXBXW group showed superior TCM syndrome score, TCM curative effect, and hs-CRP (P<0.05, P<0.01) to the control group. The dapagliflozin group was superior to the control group in terms of TCM syndrome score, NT-proBNP, and sST2 (P<0.05, P<0.01) after 1 week of treatment and in terms of NYHA class, KCCQ score, NT-proBNP, sST2, and hospital stay (P<0.05, P<0.01) after 2 weeks of treatment. The SXBXW + dapagliflozin group exhibited better efficacy than the control group in terms of NYHA class, 6MWT score, KCCQ score, TCM syndrome score and curative effect, NT-proBNP, sST2, IL-6, and hs-CRP (P=0.014) after 1 week of treatment and in terms of NYHA class, KCCQ score, TCM syndrome score and curative effect, NT-proBNP, sST2, IL-6, hs-CRP, and hospital stay (P<0.01) after 2 weeks of treatment. ConclusionSXBXW and dapagliflozin have good therapeutic effect on acute HFrEF and syndrome of Qi deficiency and blood stasis, and their combination demonstrated better therapeutic effect, with good safety and tolerability.

ABSTRACT

To investigate the effect of Fufang yinhua jiedu (FFYH) granules against coronavirus and its potential mechanism, we used Huh7, Huh7.5, H460, and C3A cell lines as in vitro models to evaluate the cytotoxicity and antiviral activity of FFYH by observation of cell pathogenic effect (CPE); and then the inhibitory effect of FFYH on the transcription expression of coronavirus RNA and inflammatory factor mRNA were evaluated by quantitive reverse transcription PCR (qRT-PCR); finally, the inhibitory effect of FFYH on the expression of coronavirus protein and its underlying mechanism against coronavirus were investigated by Western blot and immunofluorescence. Our results indicated that 50% toxic concentration (TC50) FFYH on Huh7, Huh7.5, H460, and C3A cells were 2 035.21, 5 245.69, 2 935.28 and 520 µg·mL-1, respectively; 50% inhibitory concentration (IC50) of FFYH on HCoV-229E in Huh7 and Huh7.5 cells were 438.16 and 238.54 µg·mL-1 with safety index (SI) of 4.64 and 21.99, respectively; IC50 of FFYH on HCoV-OC43 in H460 cells was 165.13 µg·mL-1 with SI of 17.78. Moreover, FFYH not only could inhibit the replication of coronaviruses (HCoV-OC43 and HCoV-229E) through inhibiting the transcription of viral RNA and the expression of viral protein, but also effectively suppress the expression of inflammatory factors interleukin-6 (IL-6), tumor necrosis factor α (TNF-α) and interleukin-8 (IL-8) at mRNA level caused by coronaviruses, which might be associated with the inhibitory effect of FFYH on mitogen-activated protein kinase (MAPK) pathway and the nuclear translocation of nuclear transcription factor-κB (NF-κB). In summary, our results demonstrated that FFYH exhibited a good in vitro anti-coronavirus effect, which provides a theoretical basis for its clinical use in the treatment of anti-coronavirus pneumonia.

ABSTRACT

Precisely delivering combinational therapeutic agents has become a crucial challenge for anti-tumor treatment. In this study, a novel redox-responsive polymeric prodrug (molecular weight, MW: 93.5 kDa) was produced by reversible addition-fragmentation chain transfer (RAFT) polymerization. The amphiphilic block polymer-doxorubicin (DOX) prodrug was employed to deliver a hydrophobic photosensitizer (PS), chlorin e6 (Ce6), and the as-prepared nanoscale system [NPs(Ce6)] was investigated as a chemo-photodynamic anti-cancer agent. The glutathione (GSH)-cleavable disulfide bond was inserted into the backbone of the polymer for biodegradation inside tumor cells, and DOX conjugated onto the polymer with a disulfide bond was successfully released intracellularly. NPs(Ce6) released DOX and Ce6 with their original molecular structures and degraded into segments with low MWs of 41.2 kDa in the presence of GSH. NPs(Ce6) showed a chemo-photodynamic therapeutic effect to kill 4T1 murine breast cancer cells, which was confirmed from a collapsed cell morphology, a lifted level in the intracellular reactive oxygen species, a reduced viability and induced apoptosis. Moreover, ex vivo fluorescence images indicated that NPs(Ce6) retained in the tumor, and exhibited a remarkable in vivo anticancer efficacy. The combinational therapy showed a significantly increased tumor growth inhibition (TGI, 58.53%). Therefore, the redox-responsive, amphiphilic block polymeric prodrug could have a great potential as a chemo-photodynamic anti-cancer agent.

ABSTRACT

Objective:To explore superior mediastinal lymph node zoning of thyroid cancer for accurate anatomical definition as a reference for surgical access. Methods:A method for zoning superior mediastinal lymph nodes for thyroid cancer was proposed. From Sep 2018 to Nov 2019, 36 cases of thyroid cancer with superior mediastinal lymph nodes metastases were reviewed. The diagnosis, surgical approaches, pathology, characteristics of lymph node metastasis, complications and follow-up results were analyzed.Results:The superior mediastinal lymph nodes were grouped into 10 areas: 1, 2Ra, 2Rb, 2La, 2Lb, 3A, 3P, 4R, 4La and 4Lb. According to the location of the superior mediastinum metastatic lymph nodes, direct vision approach through the neck incision, laparoscope-assisted approach, thracoscepy, laparoscope-assisted combined with thrascopy approach or conventional median sternotomy was performed for regional lymph node dissection. The average follow-up time was (10±4) months. No residual or recurrence of tumor in superior mediastinal area was found.Conclusions:The zoning of the superior mediastinal lymph nodes in thyroid cancer can be used as a guide for surgical approach to lymph node dissection .

ABSTRACT

Objective:To investigate the potential factors influencing the extent of coronary artery lesion in acute coronary syndrome (ACS) patients with an emphasis on the role of serum SIRT1.Methods:We assessed the clinical data from 81 ACS patients admitted to China-Japan Friendship Hospital. Serum SIRT1 was detected by enzyme linked immunosorbent assay (ELISA), and the extent of coronary artery lesion was evaluated by SYNTAX score before revascularization. All the patients were divided into two groups: high SYNTAX score (severe coronary artery lesion, n=38) and low SYNTAX score (moderate coronary artery lesion, n=43), by means of the median of SYNTAX score. Potential factors influencing SYNTAX score were analyzed through multiple linear regression analysis. Results:Compared with the low SYNTAX score group, patients in the high SYNTAX score group had higher serum SIRT1 level [379.38 (490.14) ng/L vs. 242.95 (173.85) ng/L, P<0.001] and frequency of coronary artery disease family history (42.11% vs. 20.93%, P=0.039). There was no statistical difference among other factors between the two groups. Serum SIRT1 was positively correlated with SYNTAX score in ACS patients ( R=0.452, P<0.010). Serum SIRT1 (ln adjusted), age and estimated glomerular filtration rate were independently correlated with SYNTAX score (ln adjusted) in multiple linear regression analysis (Adjusted R2=0.330, P<0.001). Conclusions:For the first time, we discussed the correlation of serum SIRT1 with extent of coronary artery lesion in ACS patients. Cardiologists should pay more attention to high-risk patients in order to improve the prognosis of ACS patients through timely revascularization strategies.

ABSTRACT

Multi-modal therapeutics are emerging for simultaneous diagnosis and treatment of cancer. Polymeric carriers are often employed for loading multiple drugs due to their versatility and controlled release of these drugs in response to a tumor specific microenvironment. A theranostic nanomedicine was designed and prepared by complexing a small gadolinium chelate, conjugating a chemotherapeutic drug PTX through a cathepsin B-responsive linker and covalently bonding a fluorescent probe pheophorbide a (Ppa) with a branched glycopolymer. The branched prodrug-based nanosystem was degradable in the tumor microenvironment with overexpressed cathepsin B, and PTX was simultaneously released to exert its therapeutic effect. The theranostic nanomedicine, branched glycopolymer-PTX-DOTA-Gd, had an extended circulation time, enhanced accumulation in tumors, and excellent biocompatibility with significantly reduced gadolinium ion (Gd

ABSTRACT

OBJECTIVE@#Bushen Tiansui formula (BSTSF), a traditional Chinese medicine prescription, has been widely used to treat Alzheimer's disease (AD). However, the mechanisms underlying its effects remain largely unknown. In this study, a rat AD model was used to study the effects of BSTSF on cognitive performance and expression of transfer RNA-derived small RNAs (tsRNAs) in the hippocampus, to determine whether treatment of AD with BSTSF could regulate the expression of tsRNAs, a novel small non-coding RNA.@*METHODS@#To generate a validated AD model, oligomeric amyloid-β@*RESULTS@#The learning and memory deficits of Aβ@*CONCLUSION@#This study identified a previously uncharacterized mechanism underlying the effects of BSTSF in alleviating the learning and memory deficits in Aβ

ABSTRACT

Objective To observe the protective effect of bisoprolol against hypoxia/reoxygenation injury of cardiac microvascular endothelial cells and explore the mechanism. Methods Left ventricular of cardiac microvascular endothelial cells (CMECs) were isolated from 8-week-old male C57BL/6N mice. CMECs were randomized into four groups: control group, vehicle group, hypoxia/reoxygenation group (H/R group), hypoxia/reoxygenation + bisoprolol group. The level of cell proliferation, apoptosis, superoxide anion, Cleaved caspase-3 and Nox2 expression were measured in each group. Results Compared with control group, H/R group had lower cell proliferation, higher apoptotic level, more superoxide anion level and the expression of Cleaved caspase-3 and Nox2 (P < 0.05). Furthermore, bisoprolol reversed hypoxia/reoxygenation-induced the decreased cell proliferation, the increased apoptosis, superoxide anion level, Cleaved caspase-3 and Nox2 expression (P < 0.05). Conclusion Bisoprolol can protect CMECs against hypoxia/reoxygenation injury by reducing the expression of Nox 2 that decreases oxidative stress.

ABSTRACT

Objective:To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in the treatment of post stroke cognitive impairment (PSCI). Method:Seven databases, including CNKI, WanFang, VIP, CBM, PubMed, The Cochrane library and ClinicalTrials.gov, were electronically searched for relevant randomized controlled trials (RCTs) of TCM in the treatment of PSCI. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of the included studies, descriptive analysis was carried out on the included studies, and the Meta quantitative analysis was carried out with RevMan 5.3 software. Result:A total of 16 RCTs were included with 1 296 participants, and they were assigned to the intervention group (n=649) and the control group (n=647). The results showed that TCM combined with western medicine group and TCM group were better than western medicine group in improving the scores of Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE), Barthel Index (BI), Activity of Daily Living (ADL), Chinese stroke scale (CSS) and National Institutes of Health stroke scale (NIHSS) of PSCI patients, and no serious adverse events were observed. Conclusion:TCM has potential advantages in improving the cognitive function of patients with PSCI, and it also has certain efficacy in improving the daily living ability and neurological impairment symptoms, and no serious adverse events have been observed. Due to the low quality of methodology included in the studies, in order to provide reliable basis for clinical decision-making, high-quality of RCTs are still needed to study the efficacy and safety of TCM for PSCI.
