Role of SIRTl/Nrf2/HO-l pathway in attenuation of learning and memory impairment by sevoflurane postcondition in a mouse model of hemorrhagic shock and resuscitation / 中国药理学通报

Aim To explore the role of SIRT1/Nrf2 / HO-1 in alleviating the cognitive function impairment by sevoflurane treatment in a mouse model of postoperative cerebral reperfusion. Methods C57BL/6J mice were randomly divided into five groups: sham operation group, hemorrhagic shock reperfusion group, sevoflurane postconditioning group, sevoflurane postcondition-ing + SIRT1 inhibitor group and sevoflurane postconditioning + Nrf2 inhibitor group. Mice were subjected to Morris water maze test after cerebral ischemia reperfusion. The ATP, superoxide dismutase (SOD), ROS and MDA contents in tissue of mice were detected. SIRT1, Nrf2 and HO-1 proteins in tissue were detected by Western blot. Results After hemorrhagic shock, the learning and memory ability of mice was reduced.ATP and SOD concentration in hippocampus was reduced , MDA and ROS concentration increased, and the SIRT, Nrf2 and HO-1 concentration was reduced. Sevoflurane improved the cognitive dysfunction and oxi-dative damage in postoperative mice, and the neuro-protective effect of sevoflurane on hemorrhagic shock and resuscitation mice was weakened followed with SIRT1 and Nrf2 inhibitors. Conclusion Sevoflurane probably alleviates the oxidative reaction damage and cognitive impairment caused by cerebral reperfusion in mice through SIRT1/Nrf2/H0-1 pathway.

The impact of amygdala glutamate receptors on cardiovascular function in rats with post-traumatic stress disorder / 生理学报

Post-traumatic stress disorder (PTSD) has been reported to be associated with a higher risk of cardiovascular disease. The amygdala may have an important role in regulating cardiovascular function. This study aims to explore the effect of amygdala glutamate receptors (GluRs) on cardiovascular activity in a rat model of PTSD. A compound stress method combining electrical stimulation and single prolonged stress was used to prepare the PTSD model, and the difference of weight gain before and after modeling and the elevated plus maze were used to assess the PTSD model. In addition, the distribution of retrogradely labeled neurons was observed using the FluoroGold (FG) retrograde tracking technique. Western blot was used to analyze the changes of amygdala GluRs content. To further investigate the effects, artificial cerebrospinal fluid (ACSF), non-selective GluR blocker kynurenic acid (KYN) and AMPA receptor blocker CNQX were microinjected into the central nucleus of the amygdala (CeA) in the PTSD rats, respectively. The changes in various indices following the injection were observed using in vivo multi-channel synchronous recording technology. The results indicated that, compared with the control group, the PTSD group exhibited significantly lower weight gain (P < 0.01) and significantly decreased ratio of open arm time (OT%) (P < 0.05). Retrograde labeling of neurons was observed in the CeA after microinjection of 0.5 µL FG in the rostral ventrolateral medulla (RVLM). The content of AMPA receptor in the PTSD group was lower than that in the control group (P < 0.05), while there was no significant differences in RVLM neuron firing frequency and heart rate (P > 0.05) following ACSF injection. However, increases in RVLM neuron firing frequency and heart rate were observed after the injection of KYN or CNQX into the CeA (P < 0.05) in the PTSD group. These findings suggest that AMPA receptors in the amygdala are engaged in the regulation of cardiovascular activity in PTSD rats, possibly by acting on inhibitory pathways.

Scientific basis of acupuncture on mesenchymal stem cells for treating ischemic stroke / 中国针灸

The scientific basis of acupuncture on mesenchymal stem cells (MSCs) for treating ischemic stroke (IS) is discussed. MSCs transplantation has great potential for the treatment of tissue damage caused by early stage inflammatory cascade reactions of IS, but its actual transformation is limited by various factors. How to improve the homing efficiency of MSCs is the primary issue to enhance its efficacy. As such, the possible mechanisms of acupuncture and MSCs transplantation in inhibiting inflammatory cascade reactions induced by IS are explored by reviewing literature, and a hypothesis that acupuncture could promote the secretion of stromal cell-derived factor-1α (SDF-1α) from ischemic foci to regulate SDF-1α/CXC chemokine receptor 4 (CXCR4) axis, thereby improving the homing efficiency of MSCs transplantation, exerting its neuroprotective function, and improving the bed transformation ability, is proposed.

Research progress in bioanalysis and pharmacokinetics of liposome nanomedicine / 药学学报

Liposome nanomedicine is a new drug preparation with nano scale, which is encapsulated by lipid bilayer vesicle structure. As a drug delivery carrier, liposome has many advantages such as good biocompatibility, biodegradation in vivo and strong targeting. The application of liposome nano drug delivery system can improve the pharmacokinetic behavior and efficacy of some drugs in vivo to a certain extent, and reduce toxic and side effects. After liposome nanomedicine enter into the body, free drugs will be released, so there will be loaded drugs and free drugs in the body. Loaded drugs are drug repositories, free drugs are related to their efficacy and adverse reactions. Therefore, the pharmacokinetics study of liposomes should focus on both loaded drugs and free drugs. Quantitative analysis of free drugs, liposome particles and their materials is a big challenge. The bioanalysis and pharmacokinetics of liposome nanomedicines will be introduced and discussed in this review. We hope this review will provide a reference for the development of liposome nanomedicine.

Research progress on the application of deep learning in choroidal segmentation / 国际眼科杂志(Guoji Yanke Zazhi)

In recent years, ophthalmology, as one of the medical fields highly dependent on auxiliary imaging, has been at the forefront of the application of deep learning algorithm. The morphological changes of the choroid are closely related to the occurrence, development, treatment and prognosis of fundus diseases. The rapid development of optical coherence tomography has greatly promoted the accurate analysis of choroidal morphology and structure. Choroidal segmentation and related analysis are crucial for determining the pathogenesis and treatment strategies of eye diseases. However, currently, choroidal mainly relies on tedious, time-consuming, and low-reproducibility manual segmentation. To overcome these difficulties, deep learning methods for choroidal segmentation have been developed in recent years, greatly improving the accuracy and efficiency of choroidal segmentation. The purpose of this paper is to review the features of choroidal thickness in different eye diseases, explore the latest applications and advantages of deep learning models in measuring choroidal thickness, and focus on the challenges faced by deep learning models.

Comprehensive Diagnosis of Mantle Cell Lymphoma / 中国实验血液学杂志

OBJECTIVE@#To explore the value of multiple detection methods based on histopathology and supplemented by bone marrow or peripheral blood sample detections in the comprehensive diagnosis of mantle cell lymphoma (MCL).@*METHODS@#The clinical, immunophenotypic, pathologic, cytogenetic and molecular features of 153 newly diagnosed MCL patients admitted to the hematology department of our hospital from May 2009 to September 2022 were analyzed.@*RESULTS@#144 (96.6%) of the 149 MCL patients who underwent marrow or peripheral blood IGH/CCND1 FISH detection at initial diagnosis were positive, of which 36 cases (24.2%) had a low proportion positive. The immunophenotypes in 115 patients were analyzed by flow cytometry (FCM), 89 cases (77.4%) conformed to MCL while 23 cases (20.0%) were initially diagnosed as B-cell lymphoproliferative disorders (B-LPD). Of the 75 cases who performed bone marrow biopsy, 50 cases (66.7%) had morphological and immunophenotypic characteristics consistent with MCL, 15 cases (20.0%) were classified as B-LPD, and 10 cases with no obvious abnormality. 77 patients underwent histopathology examination, of which 73 cases (94.8%) had typical clinicopathological features of MCL, including 2 CCND1 negative MCL, 2 pleomorphic variants, 5 pleomorphic variants and 4 cases diagnosed as other leukemia or lymphoma. Among 153 cases of MCL, 128 cases were classic MCL(cMCL), and another 25 cases (16.3%) were diagnosed as leukemic non-lymph node MCL (lnnMCL). The incidence of IGHV mutation, TP53 mutation and CD23 expression positive were significantly different between cMCL and lnnMCL.@*CONCLUSION@#Histopathology is still the main standard for the diagnosis of cMCL, and detection based on bone marrow or peripheral blood samples is an important means for the diagnosis of lnnMCL. Single marker or examination can cause a certain proportion of misdiagnosis. The accurate diagnosis of MCL depends on a combination of multiple detection methods.

Effects of Methionine Restriction on Proliferation, Cell Cycle, and Apoptosis of Human Acute Leukemia Cells / 中国实验血液学杂志

OBJECTIVE@#To investigate the effects of methionine restriction on proliferation, cell cycle and apoptosis of human acute leukemia cells.@*METHODS@#Cell Counting Kit-8 (CCK-8) assay was used to detect the effect of methionine restriction on HL-60 and Jurkat cells proliferation. The effect of methionine restriction on cell cycle of HL-60 and Jurkat cells was examined by PI staining. Annexin V-FITC / PI double staining was applied to detect apoptosis of HL-60 and Jurkat cells following methionine restriction. The expression of cell cycle-related proteins cyclin B1, CDC2 and apoptosis-related protein Bcl-2 was evaluated by Western blot assay.@*RESULTS@#Methionine restriction significantly inhibited the proliferation of HL-60 and Jurkat cells in a time-dependent manner (HL-60: r =0.7773, Jurkat: r =0.8725), arrested the cells at G2/M phase (P < 0.001), and significantly induced apoptosis of HL-60 and Jurkat cells (HL-60: P < 0.001; Jurkat: P < 0.05). Furthermore, Western blot analysis demonstrated that methionine restriction significantly reduced the proteins expression of Cyclin B1 (P < 0.05), CDC2 (P < 0.01) and Bcl-2 (P < 0.001) in HL-60 and Jurkat cells.@*CONCLUSION@#Acute leukemia cells HL-60 and Jurkat exhibit methionine dependence. Methionine restriction can significantly inhibit the proliferation, promote cell cycle arrest and induce apoptosis of HL-60 and Jurkat cells, which suggests that methionine restriction may be a potential therapeutic strategy for acute leukemia.

Evidence mapping analysis of traditional Chinese medicine intervention in pulmonary fibrosis / 中国中药杂志

This study utilized evidence mapping methodology to systematically identify, describe, and evaluate the evidence from relevant research on traditional Chinese medicine(TCM) interventions in patients with pulmonary fibrosis. CNKI, Wanfang, VIP, SinoMed, PubMed, Web of Science, EMbase, and Cochrane Library were searched from database inception to March 2023 for systematic reviews/Meta-analysis/network Meta-analysis on TCM interventions in pulmonary fibrosis. The quality of included studies was assessed using the AMSTAR 2 scale, and the evidence mapping approach was employed to present comprehensive information on populations, intervention methods, the sample size in systematic reviews/Meta-analysis, and conclusion classifications. Ultimately, 44 systematic reviews/Meta-analysis/network Meta-analysis were included. Apart from syndrome differentiation and treatment, TCM injections accounted for a significant proportion of the observed interventions. The treatment methods were mainly focused on nourishing Qi and Yin, promoting blood circulation, resolving stasis, and dredging collaterals. The results from the included studies demonstrated that TCM treatment for pulmonary fibrosis could improve efficacy, increase lung function, improve PaO_(2 )levels, increase the 6-minute walk distance(6MWD), alleviate clinical symptoms, and enhance patients' quality of life. Based on the assessment using the AMSTAR 2 scale, methodological issues were identified, including the lack of protocol registration, failure to provide a list of excluded literature, and incomplete explanations regarding the impact of heterogeneity and bias on the results. The evidence mapping revealed that 42 conclusions were beneficial, while two conclusions were potentially beneficial. Overall, the quality of evidence was relatively low, primarily due to methodological imprecision and publication bias. Although TCM showed certain efficacy in the treatment of pulmonary fibrosis, the quality of reported literature, methodological quality, and overall evidence quality need improvement. It is recommended to conduct high-quality and standardized studies in the future to provide better evidence-based guidance.

Effects of Compound Danshen Dripping Pills on Ventricular Remodeling and Cardiac Function after Acute Anterior Wall ST-Segment Elevation Myocardial Infarction (CODE-AAMI): Protocol for a Randomized Placebo-Controlled Trial / 中国结合医学杂志

BACKGROUND@#Ventricular remodeling after acute anterior wall ST-segment elevation myocardial infarction (AAMI) is an important factor in occurrence of heart failure which additionally results in poor prognosis. Therefore, the treatment of ventricular remodeling needs to be further optimized. Compound Danshen Dripping Pills (CDDP), a traditional Chinese medicine, exerts a protective effect on microcirculatory disturbance caused by ischemia-reperfusion injury and attenuates ventricular remodeling after myocardial infarction.@*OBJECTIVE@#This study is designed to evaluate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function after AAMI on a larger scale.@*METHODS@#This study is a multi-center, randomized, double-blind, placebo-controlled, parallel-group clinical trial. The total of 268 patients with AAMI after primary percutaneous coronary intervention (pPCI) will be randomly assigned 1:1 to the CDDP group (n=134) and control group (n=134) with a follow-up of 48 weeks. Both groups will be treated with standard therapy of ST-segment elevation myocardial infarction (STEMI), with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets 3 times daily after pPCI, and the control group treated with a placebo simultaneously. The primary endpoint is 48-week echocardiographic outcomes including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), and left ventricular end-systolic volume index (LVESVI). The secondary endpoint includes the change in N terminal pro-B-type natriuretic peptide (NT-proBNP) level, arrhythmias, and cardiovascular events (death, cardiac arrest, or cardiopulmonary resuscitation, rehospitalization due to heart failure or angina pectoris, deterioration of cardiac function, and stroke). Investigators and patients are both blinded to the allocated treatment.@*DISCUSSION@#This prospective study will investigate the efficacy and safety of CDDP in improving ventricular remodeling and cardiac function in patients undergoing pPCI for a first AAMI. Patients in the CDDP group will be compared with those in the control group. If certified to be effective, CDDP treatment in AAMI will probably be advised on a larger scale.

Plastic and reconstruction surgery for non-healing wound after posterior spinal surgery / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinical significance of different plastic surgeries in the treatment of poor healing wound after posterior spinal internal fixation.@*METHODS@#In this study, 16 patients with poor incision healing after posterior spinal internal fixation were retrospectively included, and dif-ferent plastic surgery treatment plans were determined according to the wound characteristics and defect condition. The measures included debridement, vacuum sealing drainage (VSD), and different tissue flaps according to the location and extent of the defect.@*RESULTS@#A total of 16 patients meeting the criteria were included, of whom 3 were treated with debridement combined with VSD and wound suture directly, 6 were treated with debridement combined with Z-flap for wound repair, 1 was treated with bilateral sacrospinous muscle flap for dural defect repair combined with Z-flap for skin wound repair, 1 was treated with lectus dorsi flap for wound repair, 3 were treated with the fourth lumbar artery perforator flap for wound repair. The wound was repaired with local rotating flap in 1 case and gluteus maximus musculocutaneous flap in 1 case. Among the 16 patients, 7 cases were positive for wound culture, including 3 cases of Staphylococcus aureus, 1 case of Pseudomonas aeruginosa, 1 case of Staphylococcus epidermidis, 1 case of Escherichia coli, 1 case of Klebsiella pneumoniae, and the other 9 cases were negative. After surgery, there were 7 patients with different degrees of poor wound healing, including 3 patients undergoing dressing change, 2 patients undergoing secondary debridement and suture, 1 patient undergoing free scalp skin graft, and 1 patient undergoing local effusion suction treatment. All the above 7 patients were discharged from hospital after improvement, and the remaining 9 patients had good first-stage wound hea-ling after surgery. None of the 16 patients underwent internal fixation.@*CONCLUSION@#Multiple factors could lead to poor wound healing after posterior spinal internal fixation. Early intervention, thorough debridement, removal of necrotic/infected tissue, and selection of suitable skin flap for effective wound fil-ling and covering were important means to ensure wound healing after spinal surgery and reduce removal of internal fixation.

OBJECTIVE@#The transformations that occur in diterpenoid alkaloids during the process of sand frying for Chinese herbal medicine preparation have yet to be clarified. This study investigated the structural changes that take place in 3-acetylaconitine during a simulation of heat-processing and evaluated the toxicity and biological activity of the pyrolysis products.@*METHODS@#The diterpenoid alkaloid 3-acetylaconitine was heated at 180 °C for 15 min to simulate the process of sand frying. The pyrolysis products were separated using column chromatography, and their structures were investigated using high-resolution electrospray ionization mass spectroscopy and nuclear magnetic resonance spectroscopy. Further, in vivo cardiotoxicity and acute toxicity of 3-acetylaconitine and its pyrolysis products were compared, and the aconitine-induced arrhythmia model was employed to evaluate the antiarrhythmic effect of the pyrolysis products.@*RESULTS@#Two new diterpenoid alkaloids, pyroacetylaconitine and 16-epi-pyroacetylaconitine, a pair of epimers at C-16, were isolated. After comparing the structures of these compounds, possible transformation pathways were proposed. Compared with the prototype compound, 3-acetylaconitine, the cardiotoxicity and acute toxicity of the heat-transformed products were significantly decreased. In the biological activity assay, the two pyrolysis products exhibited an effective increase in ventricular premature beat latency, a reduction in the occurrence of ventricular tachycardia, as well as an increase in the rate of arrhythmia inhibition, implying strong antiarrhythmic activity.@*CONCLUSION@#Compared with 3-acetylaconitine, its pyrolysis products displayed lower toxicity and good antiarrhythmic effects; thus, they have potential for being developed into antiarrhythmic medicines.

Feasibility and clinical benefits of the double-ProGlide technique for hemostasis after cryoballoon atrial fibrillation ablation with uninterrupted oral anticoagulants / 老年心脏病学杂志（英文版）

OBJECTIVE@#To access the efficacy and safety of the double-ProGlide technique for the femoral vein access-site closure in cryoballoon ablation with uninterrupted oral anticoagulants (OAC), and its impact on the electrophysiology laboratory time as well as hospital stay after the procedure in this observational study.@*METHODS@#Patients with atrial fibrillation undergoing cryoballoon ablation with uninterrupted OAC at Department of Cardiology, Beijing Anzhen Hospital, Capital Medical University, Beijing, China from May 2019 to May 2021 were enrolled in this study. From October 2020, double-ProGlide technique was consistently used for hemostasis (ProGlide group), and before that conventional manual compression was utilized (manual compression group). The occurrence of vascular and groin complications was accessed during the hospital stay and until the three-month follow-up.@*RESULTS@#A total of 140 participants (69.30% of male, mean age: 59.21 ± 10.29 years) were evaluated, 70 participants being in each group. Immediate hemostasis was achieved in all the patients with ProGlide closure. No major vascular complications were found in the ProGlide group while two major vascular complications were occurred in the manual compression group. The incidence of any groin complication was obviously higher in subjects with manual compression than patients with ProGlide devices (15.71% vs. 2.86%, P = 0.009). In addition, compared with the manual compression group, the ProGlide group was associated with significantly shorter total time in the electrophysiology laboratory [112.0 (93.3-128.8) min vs. 123.5 (107.3-158.3) min, P = 0.006], time from sheath removal until venous site hemostasis [3.8 (3.4-4.2) min vs. 8.0 (7.6-8.5) min, P < 0.001], bed rest time [8.0 (7.6-8.0) h vs. 14.1 (12.0-17.6) h, P < 0.001] and hospital stay after the procedure [13.8 (12.5-17.8) h vs. 38.0 (21.5-41.0) h, P < 0.001].@*CONCLUSIONS@#Utilization of the double-ProGlide technique for hemostasis after cryoballoon ablation with uninterrupted OAC is feasible and safe, which has the clinical benefit in reducing the total electrophysiology laboratory time and the hospital stay length after the procedure.

Change trend and prediction of lung cancer mortality in Suzhou in 2001-2020 / 公共卫生与预防医学

Objective To explore the epidemiological characteristics and trend of lung cancer mortality in Suzhou, to predict the future lung cancer mortality by ARIMA model, and to provide a scientific basis for the research of lung cancer prevention and control strategy. Methods The annual change percentage (APC) was used to analyze the annual change trend of lung cancer mortality from 2001 to 2020, and the ARIMA optimal model was employed to predict the lung cancer mortality from 2021 to 2025. Results The average annual crude mortality of lung cancer in Suzhou from 2001 to 2020 was 46.45/100 000, while the standardized mortality was 23.51/100 000. In recent 20 years, the crude mortality showed an upward trend and the standardized mortality showed a downward trend (APC crude rate = 2.51%, APC standardized rate = -0.78% , P < 0.001). The standardized mortality of lung cancer in men was 3.22 times that in women. The mortality of lung cancer in people over 45 years old increased with the increase of age, but the mortality in the 30-59 years old group showed a downward trend year by year. ARIMA model predicted that the annual trend of lung cancer crude mortality will tend to be flat in the next five years. Conclusion The crude mortality rate of lung cancer in Suzhou shows an upward trend, while the standardized mortality rate decreases year by year, suggesting that we should pay attention to the prevention and control of lung cancer in the elderly, accurately identify high-risk population of lung cancer, promote health publicity and education, carry out lifestyle intervention, and popularize the early screening of lung cancer.

Mechanism of Gardeniae Fructus in ameliorating rheumatoid arthritis based on metabolomics and intestinal microbiota / 中国中药杂志

Rheumatoid arthritis(RA), a chronic autoimmune disease, is featured by persistent joint inflammation. The development of RA is associated with the disturbance of endogenous metabolites and intestinal microbiota. Gardeniae Fructus(GF), one of the commonly used medicinal food in China, is usually prescribed for the prevention and treatment of jaundice, inflammation, ache, fever, and skin ulcers. GF exerts an effect on ameliorating RA, the mechanism of which remains to be studied. In this study, ultra-perfor-mance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS)-based serum non-target metabolomics and 16S rDNA high-throughput sequencing were employed to elucidate the mechanism of GF in ameliorating RA induced by complete Freund's adjuvant in rats. The results showed that GF alleviated the pathological conditions in adjuvant arthritis(AA) rats. The low-and high-dose GF lo-wered the serum levels of interleukin(IL)-6, tumor necrosis factor-α(TNF-α), IL-1β, and prostaglandin E2 in the rats(P<0.05, P<0.01). Pathways involved in metabolomics were mainly α-linolenic acid metabolism and glycerophospholipid metabolism. The results of 16S rDNA sequencing showed that the Streptococcus, Facklamia, Klebsiella, Enterococcus, and Kosakonia were the critical gut microorganisms for GF to treat AA in rats. Spearman correlation analysis showed that the three differential metabolites PE-NMe[18:1(9Z)/20:0], PC[20:1(11Z)/18:3(6Z,9Z,12Z)], and PC[20:0/18:4(6Z,9Z,12Z,15Z)] were correlated with the differential bacteria. In conclusion, GF may ameliorate RA by regulating the composition of intestinal microbiota, α-linolenic acid metabolism, and glycerophospholipid metabolism. The findings provide new ideas and data for elucidating the mechanism of GF in relieving RA.

Research status and prospect of remyelination in multiple sclerosis based on "inflammation-tissue" homeostatic coupling / 中国中药杂志

Multiple sclerosis(MS) shows the pathological characteristics of "inflammatory injury of white matter" and "myelin repair disability" in the central nervous system(CNS). It is very essential for MS treatment and reduction of disease burden to strengthen repair, improve function, and reduce disability. Accordingly, different from the simple immunosuppression, we believe that key to strengthening remyelination and maintaining the "damage-repair" homeostasis of tissue is to change the current one-way immunosuppression strategy and achieve the "moderate pro-inflammation-effective inflammation removal" homeostasis. Traditional Chinese medicine shows huge potential in this strategy. Through literature research, this study summarized the research on remyelination, discussed the "mode-rate pro-inflammation-effective inflammation removal" homeostasis and the "damage-repair" homeostasis based on microglia, and summed up the key links in remyelination in MS. This review is expected to lay a theoretical basis for improving the function of MS patients and guide the application of traditional Chinese medicine.
