The Huangdi Neijing proposes the " using bitter herbs to nourish or purge" theory to guide clinical prescription and formulation of herbal remedies based on the physiological characteristics and functions of the five zang viscera, along with the properties and flavors of medicinal herbs. This study explored diabetic kidney disease pathogenesis and treatment based on the " using bitter herbs to nourish or purge" theory. Kidney dryness is a key pathological factor in diabetic kidney disease, and the disharmony of kidney dryness is an essential aspect of its pathogenesis. Strengthening is the primary therapeutic principle, and kidney dryness is a persistent factor throughout the occurrence and progression of diabetic kidney disease. In the early stage, the pathogenesis involves heat-consuming qi and injuring yin, leading to kidney dryness. In the middle stage, the pathogenesis manifests as qi deficiency and blood stasis in the collaterals, resulting in turbidity owing to kidney dryness. In the late stage, the pathogenesis involves yin and yang deficiency, with kidney dryness and disharmony. This study proposes the staging-based treatment based on the " need for firmness" characteristic of the kidney. The aim is to provide new insights for clinical diagnosis and treatment in traditional Chinese medicine by rationally using pungent, bitter, and salty medicinal herbs to nourish and moisturize the kidney. This approach seeks to promote precise syndrome differentiation and personalized treatment for different stages of diabetic kidney disease, thereby enhancing clinical efficacy.

Invasive fungal infections (IFIs) have become prominent global health threats, escalating the burden on public health systems. The increasing occurrence of invasive fungal infections is due primarily to the extensive application of chemotherapy, immunosuppressive therapies, and broad-spectrum antifungal agents. At present, therapeutic practices utilize multiple categories of antifungal agents, such as azoles, polyenes, echinocandins, and pyrimidine analogs. Nevertheless, the clinical effectiveness of these treatments is progressively weakened by the emergence of drug resistance, thereby substantially restricting their therapeutic utility. Consequently, there is an imperative need to expedite the discovery of novel antifungal agents. This review seeks to present an exhaustive synthesis of novel antifungal drugs and candidate agents that are either under current clinical investigation or anticipated to progress into clinical evaluation. These emerging compounds exhibit unique benefits concerning their modes of action, antimicrobial spectra, and pharmacokinetic characteristics, potentially leading to improved therapeutic outcomes relative to conventional antifungal regimens. It is anticipated that these novel therapeutic agents will furnish innovative treatment modalities and enhance clinical outcomes in managing invasive fungal infections.

AIM: To explore the clinical efficacy of 25G minimally invasive vitrectomy combined with 41G ultra-micro subretinal injection of tissue plasminogen activator(t-PA)in the treatment of subretinal hemorrhage(SMH).METHODS: Retrospective study. A totally 60 patients(60 eyes)who visited the Ophthalmology Department of Yuebei People's Hospital from June 2022 to September 2024 and were diagnosed with submacular hemorrhage were selected. According to different treatment methods, they were divided into a control group of 30 eyes(25G vitrectomy combined with intravitreal injection of t-PA)and an observation group of 30 eyes(25G vitrectomy combined with 41G subretinal injection of t-PA). The complete clearance rate of macular hemorrhage, best corrected visual acuity(BCVA), changes in intraocular pressure, central retinal thickness(CRT), the occurrence of postoperative complications were observed in the two groups of patients.RESULTS:The two groups of general data are comparable. After treatment for 7 d, the rate of complete clearance of macular hemorrhage was higher in the observation group than in the control group(100% vs 80%, P<0.05). There was no significant difference between the two groups in the comparison of BCVA at 1 d and 6 mo postoperatively(all P>0.05), and in the comparison of BCVA between the two groups at 7 d, 1, and 3 mo postoperatively, BCVA of the observation group was better than that of the control group(all P<0.05); and the intraocular pressure of the observation group was lower than that of the control group at 1 d, 7 d, and 1 mo postoperatively(all P<0.05), and there was no significant difference between the two groups in the comparison of intraocular pressure at 3 and 6 mo postoperatively(all P>0.05). There was no significant difference between the two groups in the comparison of CRT at 1 d and 6 mo postoperatively(all P>0.05), and CRT was lower than that of the control group at 7 d, 1 and 3 mo postoperatively(all P<0.05). The total incidence of complications in the observation group was not statistically different from that in the control group(0 vs 10%, P>0.05).CONCLUSION: The 25G minimally invasive vitrectomy combined with 41G ultra-microsubretinal injection of t-PA is more efficient in removing subretinal hemorrhage, promotes early anatomical restoration, and has a comparable long-term visual prognosis to the conventional method, with a favorable safety profile.

Electrical impedance tomography (EIT) represents an emerging medical functional imaging technology, which operates by applying safe-to-human excitation currents through surface-mounted electrodes, measuring boundary voltages between electrodes, and selecting appropriate image reconstruction algorithms to visualize resistivity in tomographic cross-sections. Compared to traditional medical imaging techniques, EIT offers non-invasive and radiation-free operation, high sensitivity to tissue resistivity changes, and superior temporal resolution, meeting the real-time requirements of clinical dynamic condition monitoring. This paper comprehensively reviews the research status of brain EIT technology, systematically summarizes its advantages and technical limitations in perioperative applications, and prospectively forecasts future development directions of perioperative brain EIT based on current research foundations and clinical application demands, with the aim of providing methodological references for further optimization and clinical promotion of this technology.

OBJECTIVE To compare the metabolomic characteristics of stage T1 papillary thyroid carcinoma(PTC)and nodular goiter(NG),and the relationship between metabolites and lymph node metastasis of PTC.METHODS Serum samples were collected from 60 patients with stage T1 PTC and 30 patients with NG who underwent thyroidectomy at the Department of Otolaryngology Head and Neck Surgery,Civil Aviation General Hospital between September 2021 and April 2022.The PTC group was divided into the N+ group with lymph node metastasis and the N-group without lymph node metastasis according to the presence or absence of lymph node metastasis.The serum metabolites of the N+ and N-groups and the PTC and NG groups were compared and analyzed using an ultra-performance liquid chromatography-mass spectrometry(UPLC-Q-Exactive-MS)coupled platform,and principal component analysis(PCA),partial least squares discriminant analysis(PLS-DA),and orthogonal partial least squares discriminant analysis(OPLS-DA)was performed using SIMCA-P 14.1 software.OPLS-DA modeling,combined with FDR-corrected Mann-Whitney-Wilcoxon test results and metabolite difference multiples in the two groups undergoing comparison,etc.to screen for potential small molecule metabolic markers,and to establish a joint diagnostic model by binary logistic regression analysis.RESULTS There were no significant differential metabolites between the N+ group with lymph node metastasis and the N-group without lymph node metastasis.Seven differential metabolites were found between PCA patients and NG patients,and the five relevant metabolic pathways were the pentose phosphate pathway,pentose and glucuronide interconversion,glycolysis/gluconeogenesis,fructose,and mannose metabolism,and fatty acid biosynthesis.The differential metabolite with an area under the ROC curve>0.9 was D-glyceraldehyde 3-phosphate,and another N-undecanoylglycine,uronic acid,and the area under the ROC curve for three metabolites,N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,was>0.8.CONCLUSION PTC patients differed from NG patients mainly in glucose metabolism and lipid metabolism,and D-glyceraldehyde 3-phosphate could be distinguished from NG patients with the aid of N-undecanoylglycine,uric acid,and triiodothyronine glucuronide,combined with imaging findings.Also,no significant differences in serum metabolites were found in the N+ group compared with the N-group,and the presence or absence of lymph node metastases did not affect serum metabolites in patients with stage T1 PTC.

Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Background and objective Neoantigen reactive T cell(NRT)has the ability to inhibit the growth of tumors expressing specific neoantigens.However,due to the difficult immune infiltration and the inhibition of tumor micro en-vironment,the therapeutic effect of NRT in solid tumors is limited.In this study,we designed NRT cells(7×19 NRT)that can express both interleukin-7(IL-7)and chemokine C-C motif ligand 19(CCL19)in mouse lung cancer cells,and evaluated the difference in anti-tumor effect between 7×19 NRT cells and conventional NRT cells.Methods We performed next-generation sequencing and neoantigen prediction for mouse Lewis lung carcinoma(LLC),prepared RNA vaccine,cultured NRT cells,constructed retroviral vectors encoding IL-7 and CCL19,transduced NRT cells and IL-7 and CCL19 were successfully ex-pressed,and 7×19 NRT was successfully obtained.The anti-tumor effect was evaluated in vivo and in vitro in mice.Results The 7×19 NRT cells significantly enhanced the proliferation and invasion ability of T cells by secreting IL-7 and CCL19,achieved significant tumor inhibition in the mouse lung cancer and extended the survival period of mice.The T cell infiltration into tumor tissue and the necrosis of tumor tissue increased significantly after 7×19 NRT treatment.In addition,both 7×19 NRT treatment and conventional NRT treatment were safe.Conclusion The anti-solid tumor ability of NRT cells is significantly enhanced by the arming of IL-7 and CCL19,which is a safe and effective genetic modification of NRT.

Objective To compare the analgesic effect and the effect on the success rate of reduc-tion of three doses of remifentanil combined with dexmedetomidine in the clamping reduction of cricoarytenoid joint dislocation.Methods Fifty-one patients with cricoarytenoid joint dislocation,30 males and 21 females,aged 18-80 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ-Ⅲ,were selected from April 2021 to December 2022 in the department of otolaryngology,head and neck surgery.The patients were randomly divided into three groups according to remifentanil dose:remifentanil 0.5 μg·kg-1·min-1 group(group A,n=17),remifentanil 1.0 μg·kg-1·min-1 group(group B,n=18),and remifentanil 1.5 μg·kg-1·min-1 group(group C,n=16).After admission,dexmedetomidine 0.6 μg·kg 1·h-1 was injected intravenously,and an ear,nose and throat anesthetic spray(2％lidocaine 2 ml)was used to administer surface anesthesia to the base of the tongue.A second surface anesthesia was administered to the throat at 5 minutes,and dexmedetomidine was stopped at 10 minutes.The supraglottic and periarticular cri-coarytenoid joints were subjected to superficial anesthesia for a third time under visual laryngoscope,and then remifentanil at corresponding doses was injected intravenously in three groups for 5 minutes,and the reduction operation began after the pumping was stopped.The success of the first reduction,the anesthesia quality satisfaction score of the surgeon and the recovery of remifentanil during the operation were recorded.VAS pain scores were recorded at the time of entry,3 minutes,30 minutes,and 6 hours after operation.The adverse reactions during operation and recovery were recorded.Results Compared with group B,the success rate of first reduction and the score of anesthesia quality satisfaction were significantly decreased in groups A and C(P＜0.05).Compared with group A,the ratio of additional remifentanil supplementation in groups B and C was significantly reduced,and the VAS pain score 3 minutes after surgery was significant-ly decreased(P＜0.05).Compared with group C,the proportion of mandibular manipulation ventilation in groups A and B was significantly reduced(P＜0.05).There was no significant difference in the incidence of bradyheart rate,nausea and vomiting,agitation,delirium and laryngeal spasm between the three groups.Conclusion Compared with remifentanil 0.5 and 1.5 μg·kg-1·min-1,remifentanil 1.0 μg·kg-1·min-1 combined with dexmedetomide sequential pumping provided good analgesic effect for the clamping reduction of cricoarytenoid joint dislocation,improved the success rate of the first reduction,more stable respiratory circulation and fewer perioperative adverse reactions.
