Type 2 diabetes mellitus （T2DM） and hypertension are common and frequent chronic non-communicable diseases， which often coexist in clinical practice， resulting in a large number of cardiovascular events and deaths， and their case fatality rate far exceeds that of other factors such as dyslipidemia and obesity. Based on the diagnostic standards， guidelines， and animal model evaluation methods of T2DM with hypertension at home and abroad， this study summarized， evaluated， and analyzed the characteristics of the existing animal models of T2DM with hypertension based on the clinical symptoms in traditional Chinese and Western medicine. The animal models showing high fitting degrees with the clinical symptoms in Western medicine are mainly established by injection of streptozocin （STZ） in SHR rats in the surgical induction and chemical induction methods and feeding a high-fat and high-salt diet combined with STZ injection in SD rats in the dietary induction methods. The models showcasing high fitting degrees with the clinical symptoms in traditional Chinese medicine （TCM） are mainly established by the surgical induction method. Considering the fitting degrees and the advantages and disadvantages， the ideal modeling method for T2DM with hypertension is the two-kidney， one clip （2K1C） method （a surgical induction method） combined with feeding a high-fat and high-sugar diet and STZ injection. However， the available models lack the characteristics of TCM and the evaluation indicators have poor specificity. This study found that there are few animal models of T2DM with hypertension considering the characteristics of both disease and syndrome， which may be related to the identification and attribution of TCM syndromes in animal macroscopic information. In view of this problem， it is suggested that the evaluation criteria should be established and improved for the animal models combining disease and syndrome， which can help to evaluate the fitting degree of the pathological characteristics of different syndromes in the animal models of T2DM with hypertension. In this way， ideal animal models of T2DM with hypertension can be established to simulate the disease occurrence and development in the human body. The animal models are expected to provide an ideal approach for the further research on the pathogenesis of T2DM and its prevention and treatment with TCM， which is of great significance for the treatment and prevention of T2DM with hypertension and the prognosis of its complications. At the same time， breakthroughs in the basic syndrome models of comorbidities are expected to lay a foundation for the leapfrog development of TCM research.

Severe pneumonia is one of the most common and critical respiratory diseases in clinical practice. It is characterized by rapid progression， difficult treatment， high mortality， and many complications， posing a significant threat to the life and health of patients. The pathogenesis of severe pneumonia is highly complex， and studies have shown that its occurrence and development are closely related to multiple signaling pathways. Currently， the treatment of severe pneumonia mainly focuses on anti-infection， mechanical ventilation， and glucocorticoids， but clinical outcomes are often not ideal. Therefore， finding safe and effective alternative therapies is particularly important. In recent years， with the deepening of research into traditional Chinese medicine （TCM）， it has gained widespread attention in the treatment of severe pneumonia. This paper reviewed the relationship between severe pneumonia and relevant signaling pathways in recent years and how TCM regulated these pathways in the treatment of severe pneumonia. It was found that TCM could regulate the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， NOD-like receptor protein 3 （NLRP3）， and nuclear factor E₂-related factor 2 （Nrf2） signaling pathways， playing a role in reducing the inflammatory response， inhibiting cell apoptosis and pyroptosis， improving oxidative stress， and other effects in the treatment of severe pneumonia. Among these pathways， it was found that all of them regulated inflammation to treat severe pneumonia. Therefore， reducing inflammation is the core mechanism by which Chinese medicine treats severe pneumonia. This review provides direction for the clinical treatment of severe pneumonia and offers a scientific basis for the research and development of new drugs.

The rupture of carotid vulnerable plaques is the core pathological basis for major cardiovascular and cerebrovascular events. However， the insufficient alignment between existing animal models and the clinical disease and syndrome characteristics of traditional Chinese and western medicine has limited research progress. In this study， biomedical databases in China and abroad were systematically searched， and the modeling mechanisms and evaluation systems of carotid vulnerable plaque animal models were systematically assessed based on diagnostic criteria of both traditional Chinese and western medicine. Analysis of the clinical correspondence indicated that existing animal models can be categorized into four types： simple high-fat diet， surgical induction combined with high-fat feeding， genetic engineering combined with high-fat feeding， and drug induction combined with high-fat feeding. Among these， the compound strategy of surgical induction combined with high-fat feeding has become the current mainstream approach， showing good concordance with western medicine. The study found that the double balloon injury rabbit model and the ApoE^-/- mouse carotid artery tandem constriction combined with high-fat feeding model demonstrated a high degree of clinical correspondence with both traditional Chinese and western medicine in terms of vulnerable plaque imaging and pathological features. Nevertheless， existing models still face significant technical limitations in faithfully simulating plaque pathology and in translating findings to clinical applications. To address these challenges， integrating complex comorbidity mechanism construction， multimodal dynamic mechanism monitoring， and collaborative evaluation systems of traditional Chinese and western medicine could enable the development of highly concordant carotid vulnerable plaque disease-syndrome combination animal models. Such models would provide a reproducible experimental platform for targeted drug development to regulate plaque stability and for individualized precision treatment， as well as a theoretical basis for innovation in clinical diagnostic and therapeutic strategies.

ObjectiveTo investigate the possible mechanism of Bushen Huoxue Granule （补肾活血颗粒， BHG） in treating Parkinson's disease （PD） from the perspecitve of dopamine （DA） homeostasis. MethodsSeventy-two mice were randomly divided into blank group， model group， madopar group and BHG low-， medium- and high-dose groups， with 12 mice in each group. Except for the blank group， all mice were administered intraperitoneal injections of 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine （MPTP） for 7 consecutive days to induce a PD model. On the day following the injection， BHG low-， medium- and high-dose groups were administered BHG at doses of 1.25， 2.5， and 5.0 mg/（g·d） by oral gavage， respectively， while the madopar group received madopar tablets at dose of 0.093 8 mg/（g·d） by oral gavage. The blank group and the model group were given 0.2 ml/10 g of distilled water by gavage. All treatments were given once daily for 14 days. Open field test， pole climbing test and grip test were used to evaluate the behavior of mice in each group. Immunohistochemistry was used to detect the expression of tyrosine hydroxylase （TH） in striatum. Nissl staining was used to detect the activity of striatal neurons. The contents of DA and 3,4-dihydroxyphenylacetic acid （DOPAC） in striatum were detected by ultra performance liquid chromatography tandem mass spectrometry. The number and volume of synaptic vesicles were observed by transmission electron microscope. The expression of vesicular monoamine transporter 2 （VMAT2） in striatum was detected by immunofluorescence. Western Blot was used to detect the expression of extracellular signal-regulated kinase （ERK）， phosphorylated ERK （p-ERK）， cAMP response element-binding protein （CREB）， phosphorylated CREB （p-CREB） and VMAT2 in striatum. ResultsCompared to the blank group， mice in the model group showed a significant decline in total distance and average speed in the open field test， along with an increase in total resting time； in the pole test， both the time required for the mice to turn completely downward （T-turn） and the total time taken to reach the bottom of the pole （T-total） were prolonged； forelimb grip strength was reduced； in the striatum， the mean optical density of TH， the average fluorescence intensity of VMAT2 protein， and DA content all decreased， while the number of striatal neurons was reduced， and the DOPAC/DA ratio was elevated； the levels of p-ERK/ERK， p-CREB/CREB， and VMAT2 in the striatum significantly decreased （P＜0.01）； transmission electron microscopy revealed that both the number and volume of synaptic vesicles in striatal neurons were markedly reduced. Compared to the model group， mice in the madopar group and BHG low-， medium- and high-dose groups showed significant improvements in all the above indicators （P＜0.05 or P＜0.01）. Compared to madopar group， the BHG high-dose group exhibited increased DA content and elevated p-CREB/CREB ratio in the striatum （P＜0.05）. Compared to the BHG low-dose group， the BHG high-dose group showed increased total distance and mean velocity， decreased total resting time， T-turn， and T-total， as well as enhanced forelimb grip strength； moreover， the average fluorescence intensity of VMAT2 protein， DA content， p-ERK/ERK， p-CREB/CREB， and VMAT2 levels in the striatum were all significantly elevated （P＜0.05 or P＜0.01）. ConclusionBHG may restore DA homeostasis and alleviate the damage of dopaminergic neurons by regulating ERK/CREB/VMAT2 signaling pathway.

In the context of high-quality development in medical institutions, the supply-processing-distribution(SPD) management mode has gradually been widely applied. The authors described in detail the procurement, supply, inventory, distribution, and settlement management of medical consumables and in vitro diagnostic reagents in a certain hospital under the SPD mode. It was found that SPD was conducive to strengthening the supervision of medical consumables and in vitro diagnostic reagents in the hospital, ensuring quality and safety of use, reducing hospital operating costs, and improving hospital′s competitiveness. However, attention should be paid to preventing data security risks, strengthening operational management, and improving the cost-benefit analysis of in vitro diagnostic reagents.

This study investigated the primary pathogenesis and syndrome evolution of different heart failure with preserved ejection fraction(HFpEF)stages based on the classical and clinical experience of traditional Chinese medicine(TCM),combined with the clinical characteristics of pre-heart failure,symptomatic heart failure,and advanced heart failure.This study summarizes and refines the three core syndrome factors:water,deficiency and blood stasis.Water-fluid retention was observed throughout these three stages,from the beginning to the end.With the advancement of the disease,the heart yang changes from stagnation to deficiency,water-fluid retention gradually increases,blood stasis becomes increasingly prominent,and the disease location develops dynamically from the upper to the middle and lower jiao.This study proposes three methods of treating HFpEF.The main pathogenesis of pre-heart failure is lung qi dysfunction-induced water retention,which can be treated by dispersing lung qi and transforming water retention using Fuling Xingren Gancao Decoction.The primary pathogenesis of symptomatic heart failure is yang and qi deficiency-induced water retention,which can be treated with tonifying yang,supplementing qi,and transforming water retention using Shengxian Decoction combined with Linggui Zhugan Decoction.The primary pathogenesis of advanced heart failure is yang deficiency with blood stasis and water retention affecting the heart,which can be treated with tonifying yang,circulating blood,and expelling water retention using Zhenwu Tingli Decoction.Chinese medicine can be flexibly added or subtracted according to the patients'concurrent patterns.However,the daily care of patients should be considered.This study explores the staging treatment of HFpEF from water,deficiency and blood stasis to provide a TCM clinical reference for treating HFpEF.

Objective To explore the impact of pH value of the reaction system on the properties of bovine hemoglobin modified with aldehydeated polyethylene glycol(PEG-bHb).Methods PEG-bHb conjugates were synthesized under varying pH conditions(6.0,6.5,7.4 and 8.0)of the reaction system while consistent molar ratios,temperature,and reaction time were maintained.The structural and functional attributes of PEG-bHb were characterized.Results The proportion of methemoglobin decreased with an increase in pH.In a weakly acidic reaction environment,the PEG-bHb was found to be relatively highly modified.At pH 6.5,the average number of PEG chains attached to the bHb surface was 6.86±0.38.Selective PEG modification of the N-terminal α-NH2 groups was more pronounced under weakly acidic conditions.Specifically,at pH 6.5,the modification efficiency of the N-terminal α-NH2 groups of bHb by aldehyde-activated PEG reached 95.4％for the α-chains and 99.3％for the β-chains.The PEG modification influenced the heme region microenvi-ronment of bHb,with minimal structural impact observed at pH 6.5.After modification,the oxygen affinity of PEG-bHb was enhanced,the Hill coefficient was reduced,and there were significant increases in colloid osmotic pressure,viscosity,and particle size,all of which differed markedly from the unmodified bHb group(P＜0.001).Conclusion The synthesis of PEG-bHb under weakly acidic conditions can result in a high degree of selective modification of the N-terminal α-NH2 groups and an overall high degree of modification.

Purpose: The Open Payments Program (OPP), established in 2013 under the Sunshine Act, mandated medical device and pharmaceutical manufacturers to submit records of financial incentives given to physicians for public availability. The study aims to characterize the gap in real general and real research payments between man and woman urologists. Materials and Methods: The study sample included all urologists in the United States who received at least one general or research payment in the OPP database from 2015 to 2021. Recipients were identified using the National Provider Identifier and National Downloadable File datasets. Payments were analyzed by geography, year, payment type, and years since graduation.Multivariable analysis on odds of being in above the median in terms of money received was done with gender as a covariate. This analysis was also completed for all academic urologists. Results: There was a total of 15,980 urologists; 13.6% were woman, and 86.4% were man. Compared to man urologists, woman urologists were less likely to be in the top half of total payments received (odds ratio [OR] 0.62) when adjusted for other variables.When looking at academic urologists, 18.1% were woman and 81.9% were man. However, woman academic urologists were even less likely to be in the top 50% of payments received (OR 0.55). Conclusions This study is the first to characterize the difference in industry payments between man and woman urologists. The results should be utilized to educate physicians and industry, in order to achieve equitable engagement and funding for woman urologists.

OBJECTIVE To investigate whether electroacupuncture(EA)ameliorates abnormal trigeminal neuralgia(TN)orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1.METHODS A mouse infraorbital nerve transection model(pT-ION)of neuropathic pain was established,and EA or sham EA was used to treat ipsilateral acu-puncture points(GV20-Baihui and ST7-Xia-guan).Golgi-Cox staining and transmission elec-tron microscopy(TEM)were administrated to observe the changes of synaptic plasticity in the hippocampus CA1.RESULTS Stable and per-sistent orofacial allodynia and anxiety-like behav-iors induced by pT-ION were related to changes in hippocampal synaptic plasticity.Golgi stain-ings showed a decrease in the density of dendritic spines,especially mushroom-type dendritic spines,in hippocampal CA1 neurons of pT-ION mice.TEM results showed that the density of synapses,membrane thickness of the postsynap-tic density,and length of the synaptic active zone were decreased,whereas the width of the synap-tic cleft was increased in pTION mice.EA attenu-ated pT-ION-induced orofacial allodynia and anx-iety-like behaviors and effectively reversed the abnormal changes in dendritic spines and syn-apse of the hippocampal CA1 region.CONCLU-SION EA modulates synaptic plasticity of hippo-campal CA1 neurons,and reduces abnormal oro-facial pain and anxiety-like behavior,providing evidence for a TN treatment strategy.
