It is believed that diabetes complicated with coronary heart disease is closely related to the functional interplay of the heart， spleen， and kidneys. This paper proposed the concept of the heart-spleen-kidney as a unified system for understanding and treating the disease. At the early stage， spleen and kidney deficiency leads to the internal accumulation of phlegm， dampness， and turbid lipids， causing impaired blood circulation and vascular obstruction， so treatment should focus on tonify the kidneys and strengthening the spleen， activating blood circulation and resolving stasis， using the self-prescribed Tangxin Maiwen Formula （糖心脉温方）. As the disease progresses， further decline of spleen and kidney function results in inadequate nourishment of the heart， leading to blood stasis and the accumulation of phlegm， dampness， and turbid lipids， which may transform into pathogenic heat and toxins， causing heart damage， then treatment should emphasize on boosting qi and nourishing yin， clearing heat， activating blood and resolving toxins， using the self-prescribed Tangxin Maiqing Formula （糖心脉清方）. In advanced stages， three zang organs， the heart， spleen， and kidneys， become severely impaired， leading to mental activity fail to be nourished and abnormal cognitive functions， so treatment should focus on harmonizing the three zang organs simultaneously， using the self-prescribed Yunpi Tiaoxin Decoction （运脾调心汤）. This approach aims to provide a clinical framework for the diagnosis and treatment of diabetes with coronary heart disease.

Objective: To investigate the epidemiological and spatio-temporal characteristics of influenza in Jiaxing City, Zhejiang Province, so as to provide insights into perfecting the prevention and control strategies of influenza. Methods: Data of influenza in Jiaxing City from 2019 to 2023 were collected from the Chinese Disease Prevention and Control Information System. Population data of the same period were collected from the Zhejiang Health Information Network Reporting System. The epidemiological characteristics of influenza were analyzed using descriptive analysis. Vector map information was collected from the Open Street Map, and the spatio-temporal clustering characteristics of influenza were analyzed using spatial autocorrelation and spatio-temporal scanning. Results: A total of 181 501 cases of influenza were reported in Jiaxing City from 2019 to 2023, with an average annual reported incidence of 653.93/105. The majority of cases were aged 5 to <15 years (59 785 cases, 32.94%). The majority of the occupations were students (78 239 cases, 43.11%) and pre-school children (33 715 cases, 18.58%). The county (city, district) with the highest reported incidence was Haining City (1 451.70/105), and the town (street) with the highest reported incidence was Chang'an Town (1 932.78/105). Spatial autocorrelation analysis showed that the incidence of influenza in Jiaxing City from 2019 to 2023 had positive spatial correlations (all Moran's I>0, all P<0.05), with a high-high clustering in the southern region. Spatio-temporal scanning analysis showed that there was a spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with the southern region being the primary-type clustering area and the period between November and January of the following year being the clustering time. Conclusion There was a significant spatio-temporal clustering of influenza in Jiaxing City from 2019 to 2023, with winter being the peak season and the southern region being the primary area.

AIM:This study aimed to investigate the effects of sinomenine hydrochloride(SIN)on the ultra-structure of renal tissue and the expression of interferon gene-stimulating factor in db/db mice.METHODS:Sixteen 12-week-old male db/db mice were randomly divided into two groups:a model group and a sinomenine hydrochloride(SIN)group,each consisting of 8 mice.An additional 8 wild-type(WT)mice served as the normal control group.The sinome-nine hydrochloride group was administered the treatment for 8 weeks,followed by a 20-week observation period,while the normal and model groups received an equal volume of saline via gavage.Weekly measurements were taken for body weight and fasting blood glucose.Serum creatinine(SCr)and blood urea nitrogen(BUN)levels were assessed,and 24-hour uri-nary microalbumin(ALB)levels,as well as serum inflammatory cytokines interleukin-1β(IL-1β),IL-6 and tumor necro-sis factor-α(TNF-α),were determined using ELISA.Pathological changes in renal tissue were evaluated through hema-toxylin-eosin(HE)staining,while ultrastructural alterations were examined using transmission electron microscopy.Im-munohistochemistry and Western blotting were employed to assess STING protein expression in renal tissue,and STING mRNA expression was quantified via RT-qPCR.RESULTS:Compared to the normal group,the model group exhibited significant increases in BUN,ALB,and SCr levels(P<0.01),alongside elevated inflammatory markers IL-1β,IL-6,and TNF-α(P<0.01).Notable pathological changes included leukocyte wall thickening in capillaries,inflammatory cell infiltration,increased mesangial matrix,disorganized and linear alignment of podocytes,and thickening of the basement membrane.Moreover,STING protein and mRNA expression levels were significantly elevated(P<0.01).In contrast,the sinomenine hydrochloride group demonstrated significantly reduced levels of renal function markers(BUN,ALB and SCr)compared to the model group(P<0.01),as well as decreased concentrations of inflammatory factors IL-1β,IL-6,and TNF-α(P<0.01).Improvements in renal histopathology included decreased leukocyte wall thickening,reduced inflam-matory cell presence,diminished mesangial matrix,and a significant reduction in foot process fusion,alongside thinner basement membranes.Both STING protein and mRNA expression levels were also significantly lower(P<0.01).CON-CLUSION:Sinomenine hydrochloride effectively mitigates renal tissue injury,improves ultrastructural alterations,and inhibits inflammatory responses in db/db mice.Its mechanism of action appears closely linked to the downregulation of STING protein and mRNA expression.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To explore the mechanisms of Buyang Huanwu Decoction(BYHWD)in reducing oxidative stress levels to protect the blood-brain barrier(BBB)in cerebral ischemia/reperfusion injury(CIRI)rats.Methods A middle cerebral artery occlusion/reperfusion(MCAO/R)model in rats was established via wire embolization method.PeriCam PSI laser speckle flow imaging was applied to detect whether the model was successfully established.Neurological deficits in the rats were evaluated by Zea Longa score,and histopathological changes in the rat brain were observed by HE staining.The degree of brain edema was detected by the dry and wet weight method.BBB permeability was detected by Evans blue staining,and ultrastructural changes to the BBB were observed by transmission electron microscopy.The levels of ROS,MDA and SOD activities,which are related to oxidative stress,were detected using kits.The expression levels of matrix metalloproteinase-9(MMP-9)were detected by immunohistochemical staining and Western blot.The expression levels of Occludin,ZO-1,and Claudin-5 tight junction proteins were determined via immunofluorescence and Western blot.Results BYHWD reduced neurological deficit scores,alleviated brain histopathological damage,alleviated BBB structural disruption,prolonged the appearance of dense regions in the tight junction structure,attenuated edema of the brain on the ischemic side,and reduced BBB permeability in MCAO/R rats.BYHWD decreased the levels of ROS and MDA,increased the activity of SOD,decreased the expression levels of MMP-9,and increased the expression levels of Occludin,Claudin-5 and ZO-1.Conclusions BYHWD can increase BBB tight junction protein expression levels,reduce the permeability of the BBB,protect the ultrastructure of the BBB,and reduce brain edema,and its mechanisms may be related to its antioxidant activity and inhibition of MMP-9 activation.

Objectives:To analyze the safety and clinical effect of airway diagnosis in multifactor suspicious difficult airway patients with complex mouth restriction after entering the operating room.Methods:From March 2018 to May 2023, a total of 21 patients with suspicious difficult airway with complex mouth restriction were collected from the Northwest Women′s and Children′s Hospital and the Third Affiliated Hospital of Air Force Military Medical University, who were evaluated according to LEMON airway evaluation rule. Ventilation capacity score, airway airway score with soft vision mirror and comprehensive airway score of difficult airway were performed after admission to the operating room. Patients diagnosed with non-difficult airway were divided into group N and patients diagnosed with difficult airway were divided into group D. The number and proportion of patients in the two groups were counted, and the process of airway diagnosis, the way of airway establishment, the results, the frequency of hypoventilation during airway establishment, the number of intubation, and the time of airway establishment were analyzed.Results:A total of 15 patients in group N, accounting for 71.4%, underwent rapid intravenous induction nasal intubation after diagnosis of non-difficult airway, and the intubation was successful all the time. No hypoventilation occurred in all patients during intubation. A total of 6 patients in the group D, accounting for 28.6%, were assisted by pure oxygen mask ventilation after diagnosis of difficult airway, and underwent awake nasotracheal intubation after recovery. 4 patients were successfully intubated once, 2 patients were successfully intubated twice, and 1 patient experienced one hypopnea during the evaluation of ventilation capacity. The airway establishment time of the group N was (9.3±0.8)min, and that of the group D was (20.0±2.0)min, the difference was statistically significant ( P<0.05). The airway establishment time of all patients was (12.0±5.0)min, and the awake intubation time was (12.0±0.7.0)min. The proportion of patients satisfied with anesthesia in the group N was higher than that in the group D, and the difference was statistically significant ( P<0.05). No agitation during sevoflurane induction or recovery was observed in both groups. Conclusions:The diagnosis procedure of difficult airway can be safely applied to patients with multi-factor suspicious difficult airway with complex mouth restriction. Most of these patients do not have truly difficult airways; The application of difficult airway diagnosis procedures in these patients can significantly reduce unnecessary awake endotracheal intubation; Compared with the direct choice of awake intubation, following the difficult airway diagnosis procedure does not increase airway establishment time in such patients.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the role of nucleotide-binding oligomerization domain 2(NOD2)modified by palmitoyltransferase(ZDHHC5)in brain injury after cardiopulmonary resuscitation(CPR)in mice.Methods Twenty-four male C57BL/6J mice were divided into the blank group,the control group,the ZDHHC5-si group and the NOD2-si group,with 6 mice in each group.Except for the blank group without any treatment,CPR modeling was performed in the other three groups.At 24 h before CPR,mice in the ZDHHC5-si group and the NOD2-si group were injected with ZDHHC5 siRNA and NOD2 siRNA via tail vein,respectively.The modified neurological deficit scale(mNSS)was used to evaluate the neurological function at 24 h,48 h and 72 h in each group.Blood samples and brain tissue were collected 72 h after modeling.Real-time fluorescent quantitative PCR(qPCR)was used to detect ZDHHC5 and NOD2 in brain tissue.The protein expression levels of IL-1β,TNF-α and IL-6 in plasma were detected by enzyme-linked immunosorbent assay(ELISA).Colorimetric method and thiobarbituric acid(TBA)method were used to detect protein expression levels of MDA and MPO in brain tissue,respectively.Western blot assay was used to detect expression levels of Cleaved Caspase-3,ZDHHC5 and NOD2 in brain tissue.HE pathological sections of brain tissue were observed under light microscope.The pathological sections of brain tissue were observed by TUNEL under fluorescence microscope.Results Compared with the blank group,the mNSS score,the expression levels of IL-1β,TNF-α,IL-6,MDA and MPO,and the protein expression levels of Cleaved Caspase-3,ZDHHC5 and NOD2 were significantly increased(P＜0.05),and brain tissue damage and cell apoptosis were aggravated in the other three groups.Compared with the control group,the above indicators were significantly decreased in the ZDHHC5-si group and the NOD2-si group(P＜0.05),and brain tissue damage and cell apoptosis were significantly attenuated.Compared with the NOD2-si group,the above parameters were significantly decreased(P＜0.05),and brain tissue damage and cell apoptosis were further attenuated in the ZDHHC5-si group.Conclusion In the mouse CPR model,NOD2 can produce palmitoylated NOD2 after regulated by ZDHHC5,which further promotes the release of inflammatory factors and causes neuronal apoptosis,ultimately damaging brain tissue and affecting neurological function.

Objective:To evaluate the health benefits and intervention efficiency of different strategies of initiating antihypertensive therapy for the primary prevention of cardiovascular diseases in a community-based Chinese population from the Chinese electronic health records research in Yinzhou(CHERRY)study.Methods:A decision-analytic Markov model was used to simulate and compare different antihy-pertensive initiation strategies,including:Strategy 1,initiation of antihypertensive therapy for Chinese adults with systolic blood pressure(SBP)≥140 mmHg(2020 Chinese guideline on the primary preven-tion of cardiovascular diseases);Strategy 2,initiation of antihypertensive therapy for Chinese adults with SBP≥130 mmHg;Strategy 3,initiation of antihypertensive therapy for Chinese adults with SBP ≥140 mmHg,or with SBP between 130 and 140 mmHg and at high risk of cardiovascular diseases(2017 American College of Cardiology/American Heart Association guideline for the prevention,detection,evaluation,and management of high blood pressure in adults);Strategy 4,initiation of antihypertensive therapy for Chinese adults with SBP≥ 160 mmHg,or with SBP between 140 and 160 mmHg and at high risk of car-diovascular diseases(2019 United Kingdom National Institute for Health and Care Excellence guideline for the hypertension in adults:Diagnosis and management).The high 10-year cardiovascular risk was de-fined as the predicted risk over 10％based on the 2019 World Health Organization cardiovascular disease risk charts.Different strategies were simulated by the Markov model for ten years(cycles),with parame-ters mainly from the CHERRY study or published literature.After ten cycles of simulation,the numbers of quality-adjusted life years(QALY),cardiovascular events and all-cause deaths were calculated to evaluate the health benefits of each strategy,and the numbers needed to treat(NNT)for each cardiovas-cular event or all-cause death could be prevented were calculated to assess the intervention efficiency.One-way sensitivity analysis on the uncertainty of incidence rates of cardiovascular disease and probabilis-tic sensitivity analysis on the uncertainty of hazard ratios of interventions were conducted.Results:A to-tal of 213 987 Chinese adults aged 35-79 years without cardiovascular diseases were included.Com-pared with strategy 1,the number of cardiovascular events that could be prevented in strategy 2 increased by 666(95％UI:334-975),while the NNT per cardiovascular event prevented increased by 10(95％UI:7-20).In contrast to strategy 1,the number of cardiovascular events that could be prevented in strategy 3 increased by 388(95％UI:194-569),and the NNT per cardiovascular event prevented decreased by 6(95％UI:4-12),suggesting that strategy 3 had better health benefits and intervention efficiency.Compared to strategy 1,although the number of cardiovascular events that could be prevented decreased by 193(95％UI:98-281)in strategy 4,the NNT per cardiovascular event prevented decreased by 18(95％UI:13-37)with better efficiency.The results were consistent in the sensitivity analyses.Conclusion:When initiating antihypertensive therapy in an economically developed area of China,the strategy combined with cardiovascular risk assessment is more efficient than those purely based on the SBP threshold.The cardiovascular risk assessment strategy with different SBP thresholds is suggested to balance health benefits and intervention efficiency in diverse populations.
