Quantitative analysis of macular microcirculation changes in diabetic retinopathy patients by optical coherence tomography angiography / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the macular microcirculation changes in patients with diabetic retinopathy(DR)by optical coherence tomography angiography(OCTA), and correlate the risk factors that may affect the macular microcirculation, so as to provide a clinical basis for early screening, diagnosis and therapeutic intervention for DR.METHODS: Retrospective study. A total of 75 patients(75 eyes)with type 2 diabetes mellitus(DM)who came to the ophthalmology outpatient clinic and ward of Xi'an Central Hospital from May to October 2022 were collected, and the DM patients were further divided into non-DR(NDR)group, non-proliferative DR(NPDR)group and proliferative DR(PDR)group, with 28 eyes, 25 eyes and 22 eyes in each group respectively. OCTA was applied to perform a 3mm×3mm blood flow imaging scan of the macular retina to automatically obtain the vascular density(VD)of the superficial retinal macular foveal, the parafoveal(1～3mm), as well as the macular 3mm×3mm and the area of macular foveal avascular zone(FAZ). Furthermore, the alteration of these parameters in patients with different degrees of DR was analyzed.RESULTS: Compared with the NDR group, the VD of the 3mm×3mm superficial retinal capillary(SCP)in the macular region was decreased in both PDR and NPDR group(all P<0.017), and the VD of the parafoveal was decreased in each quadrant(P<0.017), with the most significant decrease in the PDR group. The FAZ area of patients in the PDR and NPDR groups was significantly larger than that in the NDR group(P<0.017). Age, homocysteine, best corrected visual acuity(LogMAR), axial length and glycosylated hemoglobin(HbA1c)of patients with DR were negatively correlated with VD in the macular foveal(P<0.05), while homocysteine, best corrected visual acuity(LogMAR), axial length, and the duration of diabetes were negatively correlated with VD in the macular 3mm×3mm(P<0.05). Triglycerides, best corrected visual acuity(LogMAR), and HbA1c were negatively correlated with VD in the parafoveal(P<0.05), while total cholesterol and central macular thickness had no significant correlation with VD(P>0.05).CONCLUSION: The microcirculation changes in the macular area of DR patients can be monitored by OCTA, and the systemic condition of DR patients is closely related to their macular microcirculation.

Improved population coverage of the human papillomavirus vaccine after implementation of a school-based vaccination programme: the Singapore experience

INTRODUCTION@#Cervical cancer has a high disease burden in Singapore, and it is strongly associated with human papillomavirus (HPV) infections. Despite constant efforts to encourage vaccination, local HPV vaccine uptake remains low. Universal mass vaccination is a proven cost-effective method to reduce the cervical cancer disease burden. This paper reviews the newly implemented school-based HPV vaccination programme in Singapore and the factors that led to its success.@*METHODS@#Fully subsidised HPV vaccinations were offered to all Secondary 1 female students on an opt-in basis, starting as a rollout dose in 2019. One-time catchup vaccination was also offered to female students in Secondary 2-5. Eligible recipients were identified using enrolment data provided by Ministry of Education schools. A total of 19,144 students across 139 schools were offered the rollout dose, and 20,854 students across 140 schools were offered the catchup doses.@*RESULTS@#High vaccine uptake rates of 80.6%-87.3% were noted with the introduction of the school-based programme, translating to high vaccine coverage of 90.3%-93.4%. Only a small proportion of students (1.5%-1.9% per cohort) opted out. The rate of reported side effects, which were commonly known effects, was low at one in 1000. Among the students who reported side effects, those who received the second vaccine dose did so uneventfully.@*CONCLUSION@#High HPV vaccine coverage was achieved after implementation of the school-based immunisation programme. Timely assessment of knowledge lapses and targeted intervention, strong partnerships with stakeholders, constant on-site adaptation and positive social influence contributed to its success. This model can be applied to future school health programmes.

Prevalence and incidence of heart failure among community in China during a three-year follow-up / 老年心脏病学杂志（英文版）

BACKGROUND@#Epidemiological surveys on heart failure (HF) in Chinese community are relatively lacking. This study aimed to estimate the prevalence and incidence of HF among community residents in southern China.@*METHODS@#Baseline data of this prospective study was collected from 2015 to 2017 among 12,013 permanent residents aged ≥ 35 years in Guangzhou, China. The same survey process was carried out for individuals aged ≥ 65 years after a three-year follow-up.@*RESULTS@#The overall prevalence of HF in community residents aged ≥ 35 years was 1.06%. Male had significantly higher risk of HF prevalence [odds ratio (OR) = 1.50, P = 0.027]. The gender-adjusted risk of HF was 1.48 times higher per 10 years aging. HF prevalence was statistically associated with atrial fibrillation, valvular heart disease, hypertension and chronic obstructive pulmonary disease after adjusting for age and gender (OR = 8.30, 5.17, 1.11, 2.28, respectively; all P < 0.05). HF incidence in individuals aged ≥ 65 years were 847 per 100,000 person-years. Baseline atrial fibrillation, valvular heart disease, and diabetes mellitus were risk factors for HF incidence for individuals aged ≥ 65 years adjusting for age and gender (OR = 5.05, 3.99, 2.11, respectively; all P < 0.05). Besides, residents with new-onset atrial fibrillation and myocardial infarction were at significantly higher risk of progression to HF (OR = 14.41, 8.54, respectively; all P < 0.05).@*CONCLUSIONS@#Both pre-existing and new-onset cardiovascular diseases were associated with HF incidence in southern China. Management of related cardiovascular diseases may be helpful to reduce the incidence of HF.

The role and treatment strategies of ferroptosis in liver diseases / 药学学报

The discovery of regulatory cell death has led to new breakthroughs in the field of disease treatment. As a novel discovered regulatory cell death in the past decade, ferroptosis is characterized by abnormal increase of intracellular iron ions and peroxidative damage of cell membrane lipids, morphological features of mitochondrial volume reduction, increased mitochondrial membrane density, as well as mitochondria decrease or disappear. The mechanism of ferroptosis is mainly associated with factors such as iron metabolism disorder, lipid metabolism abnormality, amino acid antioxidant system imbalance and oxidative stress. Since the liver is the main organ of human body for storing iron ions, it is necessary to deeply investigate the mechanism of ferroptosis in liver diseases. Relevant studies have shown that ferroptosis plays different roles in various liver diseases and is closely related to the process of liver diseases, including drug-induced liver injury, alcoholic fatty liver disease, non-alcoholic fatty liver diseases, viral hepatitis, liver fibrosis and hepatocellular carcinoma. The aim of this review is to link ferroptosis and liver diseases, concentrating on the iron metabolism disorder, accumulation of lipid peroxides in cell membranes, imbalance of amino acid antioxidant system, hyperpolarization of mitochondrial membrane potential and its accumulation of lipid peroxides, oxidative stress-related transcription factors and other aspects. This review summarizes the regulatory mechanism, current situation and the roles of ferroptosis in liver diseases, in order to provide a new theoretical basis and ideas for the in-depth study of ferroptosis and the treatment of liver diseases.

A comparative study of artificial intelligence nasal polyp classification based on whole-slide imaging and JESREC diagnostic criteria / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the types and clinical characteristics of chronic rhinosinusitis with nasal polyps (CRSwNP) based on artificial intelligence and whole-slide imaging (WSI), and to explore the consistency of the diagnostic criteria of the Japanese epidemiological survey of refractory eosinophilic chronic rhinosinusitis (JESREC) in Chinese CRSwNP patients. Methods: The data of 136 patients with CRSwNP (101 males and 35 females, aging 14 to 70 years) who underwent endoscopic sinus surgery from 2018 to 2019 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analysed retrospectively. The preoperative clinical characteristics of patients were collected, such as visual analogue scale (VAS) of nasal symptoms, peripheral blood inflammatory cell count, total immunoglobulin E (IgE), Lund-Kennedy score and Lund-Mackay score. The proportion of inflammatory cells such as eosinophils, lymphocytes, plasma cells and neutrophils were calculated on the WSI of each patient through artificial intelligence chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0), and the specific type of nasal polyps was then obtained as eosinophilic CRSwNP (eCRSwNP) or non-eosinophilic CRSwNP (non-eCRSwNP). In addition, the JESREC diagnostic criteria was used to classify the nasal polyps, and the classification results were compared with the current gold standard for nasal polyps diagnosis (pathological diagnosis based on WSI). The accuracy, sensitivity and specificity of the diagnostic criteria of JESREC were evaluated. The data were expressed in M (Q1, Q3) and statistically analyzed by SPSS 17.0. Results: There was no significant difference between eCRSwNP and non-eCRSwNP in age distribution, gender, time of onset, total VAS score, Lund-Kennedy score or Lund-Mackay score. However, there was a significant difference in the ratio of nasal polyp inflammatory cells (eosinophils 40.5% (22.8%, 54.7%) vs 2.5% (1.0%, 5.3%), neutrophils 0.3% (0.1%, 0.7%) vs 1.3% (0.5%, 3.6%), lymphocytes 49.9% (39.3%, 65.9%) vs 82.0% (72.8%, 87.5%), plasma cells 5.1% (3.6%, 10.5%) vs 13.0% (7.4%, 16.3%), χ2 value was 9.91, 4.66, 8.28, 5.06, respectively, all P<0.05). In addition, eCRSwNP had a significantly higher level of proportion of allergic symptoms (nasal itching and sneezing), asthma, peripheral blood eosinophil and total IgE (all P<0.05). The overall accuracy, sensitivity and specificity of the JESREC diagnostic criteria was 74.3%, 81.3% and 64.3%, respectively. Conclusions: The eCRSwNP based on artificial intelligence and WSI has significant high level of allergic symptoms, asthma, peripheral blood eosinophils and total IgE, and the percentages of inflammatory cells in nasal polyps are different from that of non-eCRSwNP. The JESREC diagnostic criteria has good consistency in our research.

Traditional Chinese and Western Medicine in Treatment of Postmenopausal Osteoporosis： A Review / 中国实验方剂学杂志

Postmenopausal osteoporosis （PMOP） is a systemic disease characterized by increased bone fragility caused by insufficient estrogen secretion in women after menopause，resulting in decreased bone mass and damage to the microstructure of bone tissues. The main clinical manifestations are low back pain，osteoporotic fractures，spinal deformities，and multiple organ dysfunction. PMOP directly leads to high morbidity， high mortality， and a decline in the quality of life. In addition to miss diagnosis， it is often not treated in time. In recent years， significant progress has been made in the research on factors related to the pathogenesis of PMOP. Based on the previous findings in recent years，this article described three major pathogenesis of PMOP， including intestinal flora imbalance，oxidative stress，and abnormal differentiation of bone marrow mesenchymal stem cells （BMMSCs）， and analyzed the current status of PMOP treatment， such as syndrome differentiation and treatment，acupuncture and moxibustion，exercise therapy， and external treatment in traditional Chinese medicine （TCM）， and basic measures，drug intervention，and physical therapy in western medicine. Among them，drug intervention in western medicine treatment is generally divided into bone resorption inhibitors，bone formation promoters，and other mechanism drugs according to the mechanism of action. This article summarized the specific methods and effects or mechanisms of TCM and western medicine in the clinical treatment of PMOP，which is expected to provide a reference for formulating reasonable health management models and drug treatments in the future.

Anti-oxidative stress mechanism of velvet antler polypeptide in Alzheimer's disease model mice / 解剖学报

Objective To study the effect of velvet antler polypeptides (VAP) on antioxidant in Alzheimer' s disease model mice. Methods Eight months old male amyloid precursor protein (APP)/presenilin-l (PS1) double transgenic mice were selected as Alzheimer' s disease (AD) model and divided into the model group and the VAP intervention group, 12 in each group. Besides, normal mice of the same brood (with no transgene) were recruited as a control group (n= 12).After 6 months of intragastric administration, behavior, morphology and oxidative stress related indicators were detected.SH-SY5 cells were used to establish AD model of damaged by Ap2535. The expression levels of APP and p-secreatase-l(BACE1) protein in mouse hippocampus were detected by Western blotting. VAP intervention group SH-SY5Y cells was cultured with VAP (500 g/L) and amyloid P(Ap) 2535(25 ixmol/L) for 24 hours. Control group cells were normally cultured by DMEM medium. Cell apoptosis, membrane potential, reactive oxygen species (ROS) levels and oxidative stress related indexes were detected. Results In animal models, compared with the model group, the escape latency of mice in the VAP intervention group was shortened (P<0. 05). The neuronal cells in the CA1 region of the hippocampus of the model group were reduced and arranged disorderly. The arrangement of the VAP intervention group was relatively regular, and the morphology was significantly improved. Compared with the model group, senile plaques were decreased in the VAP intervention group. Compared with the model group, the malondialdehyde (MDA) content ol the VAP intervention group increased, and the superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) content increased, the difference was statistically significant. Compared with the control group, the APP and BACE1 content in the model group increased. Compared with the model group, the contents of APP and BACE1 in the VAP intervention group decreased, and the difference was statistically significant (P<0. 05). In the cell model, the apoptosis rates of the VAP intervention group decreased. Compared with the model group, the mitochondrial membrane potential of the VAP intervention group increased, the content ol ROS decreased, the content of MDA decreased, and the content of SOD and GSH-Px increased. The difference were statistically significant (P<0. 05). Conclusion VAP has a protective effect on oxidative stress damage caused by Alzheimer' s disease model animals and cells, which may be achieved by reducing ROS production and increasing the activity of antioxidant enzymes to reduce Ap deposition.

The Role of SPHK￣S1P Axis in Angiogenesis￣related Diseases / 中国生物化学与分子生物学报

Angiogenesis refers to the process of forming new blood vessels based on original blood vessels. Pathological angiogenesis is a sign of a series of diseases such as cancer, cardiovascular diseases, and retinopathy. Sphingosine 1-phosphate (S1P) is a signaling lipid synthesized by sphingosine kinase (SPHK) that exerts its diverse biological and pathophysiological roles through five G protein-coupled receptors (S1PR1-5) and initiates various signaling cascades by activating receptors that affect cell fate, vascular tension, endothelial function and integrity, and lymphocyte transport. The imbalance ofproduction and signal is closely related to pathological processes such as endothelial dysfunction and abnormal angiogenesis. Accumulating evidence suggests that the SPHK-S1P axis plays an important role in angiogenesis, especially in the development of tumors, diabetes retinopathy, atherosclerosis, myocardial infarction and other cardiovascular diseases. Studies on its roles and functions can provide new insights and drug therapeutic targets for the treatment of angiogenesis-related diseases. This review describes the molecular mechanisms by which the SPHK-S1P axis affects endothelial cell and smooth muscle cellproliferation, endothelial cell migration and the formation of lumen by endothelial cells, pericytes and smooth muscle cells through SPHK and S1PR1-5. The review also elaborates how the SPHK-S1P axis affects angiogenesis in tumors, cardiovascular diseases, diabetes and retinopathy through SPHK and S1PR1-5, and aims to provide new therapeutic strategy for related diseases by understanding the molecular mechanism of the SPHK-S1P axis in angiogenesis.

Practical Considerations for Converting Operating Rooms and Post-anaesthesia Care Units into Intensive Care Units in the COVID-19 Pandemic - Experience from a Large Singapore Tertiary Hospital

COVID-19 has spread globally, infecting and killing millions of people worldwide. The use of operating rooms (ORs) and the post-anaesthesia care unit (PACU) for intensive care is part of surge response planning. We aim to describe and discuss some of the practical considerations involved in a large tertiary hospital in Singapore. Firstly, considerations for setting up a level III intensive care unit (ICU) include that of space, staff, supplies and standards. Secondly, oxygen supply of the entire hospital is a major determinant of the number of ventilators it can support, including those on non-invasive forms of oxygen therapy. Thirdly, air flows due to positive pressure systems within the OR complex need to be addressed. In addition, due to the worldwide shortage of ICU ventilators, the US Food and Drug Administration has granted temporary approval for the use of anaesthesia gas machines for patients requiring mechanical ventilation. Lastly, planning of logistics and staff deployment needs to be carefully considered during a crisis. Although OR and PACU are not designed for long-term care of critically ill patients, they may be adapted for ICU use with careful planning in the current pandemic.

Clinical features of Wiskott-Aldrich syndrome: an analysis of 13 cases / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features of Wiskott-Aldrich syndrome (WAS) in children.@*METHODS@#A retrospective analysis was performed for the clinical data of 13 children with WAS.@*RESULTS@#All 13 children were boys, with a median age of onset of 3 months (range 1-48 months) and a median age of 24 months (range 1-60 months) at the time of diagnosis. Of the 13 children, only 3 had typical WAS and the remaining 10 children had X-linked thrombocytopenia (XLT). The mean WAS score was 2 (range 1-3), the mean platelet count was 20.5×10/L [range (13-46)×10/L], and the mean platelet volume was 8.1 fl (range 6.7-12.1 fl). Lymphocyte subsets and immunoglobulins were measured for 4 children, among whom 1 (25%) had a reduction in both the percentage of CD3T cells per lymphocyte and lymphocyte per nuclear cells, 1(25%) had a reduction in CD3CD56 NK cells. Among these 4 children, 1 (25%) had an increase in IgG, 2 (50%) had a reduction in IgM, 1 (25%) had a reduction in IgA, and 4 (100%) had an increase in IgE. A total of 14 gene mutations belonging to 13 types were found in 13 children, among which there were 9 missense mutations (65%), 2 splicing mutations (14%), 2 nonsense mutation (14%), and 1 frameshift mutation (7%). The median follow-up time was 39 months (range 3-62 months), and all 13 children survived.@*CONCLUSIONS@#Children with WAS often have a young age of onset, and most of them are boys. Major clinical features include thrombocytopenia with a reduction in platelet volume. Missense mutation is the main type of gene mutation.
