ObjectiveTo observe the clinical efficacy and safety of Yishen Jiangtang decoction combined with conventional Western medicine treatment in managing stage G3A3 diabetic kidney disease （DKD） in the patients with the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis， and to explore its mechanism of inhibiting the endoplasmic reticulum stress （ERS）-apoptosis axis and delaying renal fibrosis （RF）. MethodsA single-center， randomized， parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine （TCM） pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group （conventional Western medicine treatment） and an experimental group （Yishen Jiangtang decoction combined with conventional Western medicine treatment）， with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters： Blood urea nitrogen （BUN）， serum creatinine （SCr）， estimated glomerular filtration rate （eGFR）， urinary albumin-to-creatinine ratio （UACR）， fasting blood glucose （FBG）， triglycerides （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C）. Enzyme-linked immunosorbent assay （ELISA） kits were used to measure serum glucose-regulated protein 78 （GRP78）， serum cysteinyl aspartate-specific protease-3 （Caspase-3）， and serum and urinary transforming growth factor-β₁ （TGF-β₁） levels before and after treatment. TCM symptom scores， TCM syndrome efficacy， and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3， as well as serum and urinary levels of TGF-β1， with renal function， proteinuria， and glucose and lipid metabolism indicators in patients with DKD. In addition， safety indicators were also monitored. ResultsA total of 75 patients completed the study （38 in the control group and 37 in the experimental group）. ① Baseline data： The two groups were comparable in terms of sex and age， with no statistically significant difference. ② Efficacy outcomes： Compared with baseline levels， both groups showed reductions in BUN， SCr， UACR， FBG， TG， TC， LDL-C， and TCM symptom scores （P<0.01） and increases in eGFR level （P<0.01）. Moreover， the experimental group outperformed the control group in altering the indicators above （P<0.05）. Regarding TCM syndrome efficacy， the total response rate in the experimental group was 83.78%， which was higher than that （57.89%） in the control group （P<0.05）. Regarding overall clinical efficacy， the total response rate in the experimental group was 78.38%， which was higher than that （50.00%） in the control group （P<0.05）. ③ Mechanism outcomes： Compared with baseline levels， both groups showed declined serum levels of GRP78， Caspase-3， and TGF-β₁ and urinary level of TGF-β₁ after treatment （P<0.01）. Moreover， the experimental group showed greater declines than the control group （P<0.05）. The serum levels of GRP78， Caspase-3，and TGF-β₁ and the urinary level of TGF-β₁ in DKD patients showed positive correlations with BUN， SCr， UACR， and FBG and negative correlations with eGFR （P<0.05）. ④ Safety outcomes： Neither group showed drug-related adverse reactions， and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms， correct glucose and lipid metabolism disorders， and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

Objective To investigate the expression of α7 nicotinic acetylcholine receptor (α7nAChR) in thymic T follicular helper cells (TFH) and its significance in patients with myasthenia gravis (MG). Methods Fifteen MG patients who underwent surgical treatment at the Myasthenia Gravis Comprehensive Diagnosis and Treatment Center of Henan Provincial People’s Hospital from June 2022 to June 2023 were selected as a MG group, including 7 males and 8 females, aged 12-30 years. Twelve patients who underwent partial thymectomy to optimize surgical field exposure during cardiac surgery at Fuwai Central China Cardiovascular Hospital from June 2022 to June 2023 were selected as a control group, including 5 males and 7 females aged 20-35 years. Thymus single cell suspension was obtained by grinding the thymus tissue, and flow cytometry was used to detect the expression of α7nAChR in TFH cells. The thymus cell suspension was purified using density gradient centrifugation, followed by immunomagnetic bead separation to obtain CD4+T cells. CXCR5 antibody and coupled magnetic beads were added to isolate TFH cells. Real-time fluorescent polymerase chain reaction and Western blotting were performed to further investigate the expression of α7nAChR in TFH cells. Results Compared with the control group, the proportion of thymic TFH cells in the MG group was significantly increased (P<0.05), along with significantly decreased mRNA and protein expression levels of α7nAChR within these cells (P<0.01). Conclusion The findings suggest that there is a reduced expression of α7nAChR within thymic TFH cells in MG patients, leading to weakened immunosuppressive function which may indirectly contribute to disease onset and progression.

Objective:To study the consistency between post-processing bone mineral density(BMD)values of multi-slice spiral computed tomography(MSCT)scan and the BMD value of quantitative computed tomography(QCT)for lumbar vertebra,so as to explore the feasibility of utilizing MSCT scan-based post-processing BMD values for lumbar vertebra in clinical practice.Methods:The MSCT equipment and QCT equipment were respectively adopted to conduct imaging scan for the L2-L4 of lumber vertebra of QRM-ESP145 European Spine Phantom(ESP),and L2-L4 of lumbar vertebra of adult sheep,and L2-L4 of lumbar vertebra of adult volunteer.The L2-L4 of ESP lumber vertebra and L2-L4 of lumbar vertebra of adult sheep were scanned respectively MSCT and QCT for three times,so as to measure BMD values.The L2-L4 of lumbar vertebrae of volunteers were scanned respectively by the two methods for one time according to the standard of clinical examination,which were reconstructed by three times so as to obtain mean of them.The BMD values of QCT scan were set as control group,and the BMD values of MSCT scan were set as experiment group.The experiment group was further divided into experiment 1 group[two dimension(2D)regional volumetric BMD values of the lumbar vertebra]and experiment 2 group[three dimension(3D)global volumetric BMD post-processing of the lumbar vertebra]according to the reliability of experiment.Then,the consistency between the MSCT 3D post-processing BMD values of three groups and QCT-measured BMD values was compared and analyzed.Results:The MSCT 3D post-processing BMD values of L2-L4 of ESP lumbar vertebra of three groups were respectively(120.83±0.97),(199.57±0.54)and(119.19±1.04)mg/cm3,and that of L2-L4 of lumbar vertebra of adult sheep of three groups were respectively(414.89±1.72),(410.50±0.77)and(420.25±2.71)mg/cm3,and that of L2-L4 of lumbar vertebra of volunteer were respectively(141.22±0.09),(137.38±0.37)and(152.03±1.03)mg/cm3.There were not statistically significant differences in BMD values between MSCT examination and QCT examination(P＞0.05).Conclusion:MSCT 3D post-processing BMD values on lumbar vertebra has high consistency with that of QCT measurements,which post-processing technique can replace QCT to conduct BMD examination,and reduce unnecessary radiation exposure and examination costs for patients.

Objective To observe the feasibility of transesophageal echocardiography(TEE)combined with agitated saline contrast echocardiography(ASCE)for identifying morphological characteristics of high-risk patent foramen ovale(PFO)and evaluating the risk of PFO related stroke.Methods Totally 212 PFO patients diagnosed by TEE combined with ASCE were enrolled,including 100 cases with cryptogenic stroke(CS)(CS group)and 112 without CS(non-CS group).Anatomical morphological characteristics of PFO were comparatively analyzed between groups to screen the independent factors of CS.Results In CS group,the left and right atrial opening diameters of PFO were all larger than those in non-CS group in both resting-state and stimulated state.The aortic root diameter in CS group was larger than that in non-CS group,and the incidence of atrial septal aneurysm(ASA),high activity of the atrial septum,inferior vena cava valve or Chiari network,large amount of right-to-left-shunt(RLS)in stimulated state,and multiple outlets of the oval valve in CS group were all higher than those in non-CS group(all P＜0.05).Logistic regression analysis showed that ASA,high atrial septal activity,large amount of RLS and multiple oval valve outlets were all independent factors associated with CS(OR=0.211,0.384,0.999,0.199,all P＜0.05).Conclusion TEE combined with ASCE could identify anatomical characteristics of high-risk PFO and assess the risk of PFO related stroke.

Alzheimer disease is a progressive neurodegenerative disorder which has emerged as a major public health concern with the global population aging, and the development of effective therapeutic agents has become increasingly urgent due to its rapid increase in prevalence. There is some progress in drug development, however, the majority of new drugs have failed to demonstrate sustained clinical efficacy in large-scale trials. In addition, high costs, severe side effects have further hindered the widespread application of these therapies. This article reviews recent progress in the development of pharmacological treatments for Alzheimer disease, focusing on disease-modifying therapies targeting amyloid-β and tau proteins, also analyzes the results of phase 2 and phase 3 clinical trials of traditional and novel drugs. Future research efforts should continue to explore novel therapeutic targets and strategies to offer more effective treatment options for patients with Alzheimer disease.

With the progress of medical insurance reform,the refinement of medical insurance management in pub-lic hospitals still fails to meet the actual demands for medical insurance work.Based on the existing problems of medical insurance management,it emphasizes the necessity of the refined management of medical insurance.By integrating be-havioral economics theory,it divides the refined management of medical insurance into five distinct stages:develop-ment planning,process-oriented platform,organizational framework,staff training programs and regulatory supervi-sion.The behavioral logic of the refined management of medical insurance in public hospitals is analyzed.Building on this analysis,the relevant key insights are summarized to provide a reference for promoting the public welfare-oriented reform of public hospitals and realizing the high-quality development of public hospitals.

Objective:To explore the time variations of the influence of the ultra-high dose rate irradiation (FLASH irradiation, FLASH-IR) and conventional dose rate irradiation (CONV-IR) of electron beams under different doses on the energy metabolism of triple-negative breast cancer cells MDA-MB-231.Methods:The basal metabolism of the MDA-MB-231 cells and normal breast epithelial cells MCF-10A was compared using a Seahorse XF Pro Metabolic Analyzer. Based on an irradiation platform with a thermionic cathode electron accelerator (6 MeV), the MDA-MB-231 cells were exposed to FLASH-IR (106 Gy/s) and CONV-IR (0.1 Gy/s) at 2 and 14 Gy, respectively. Meanwhile, a sham irradiation group was established under identical culture conditions. The mitochondrial metabolism and glycolytic metabolism of the cells at 4, 24, and 48 h post-irradiation were analyzed.Results:Compared to the MCF-10A cells, the MDA-MB-231 cells exhibited a greater reliance on glycolytic metabolism. Compared to those of the sham irradiation group, MDA-MB-231 cells in the 2 Gy CONV-IR group showed up-regulated ATP-linked respiration at 4, 24, and 48 h post-irradiation ( t = 2.69-3.70, P < 0.05). Their glycolytic level and glycolytic capacity were up-regulated only at 4 h post-irradiation and were down-regulated at 48 h ( t = 2.79, -4.44, P < 0.05). In contrast, there was no statistically significant difference in these indicators between the FLASH-IR and CONV-IR groups ( P > 0.05). However, the proton leak of the MDA-MB-231 cells in the FLASH-IR group was relatively down-regulated at 4 h post-irradiation and was significantly up-regulated at 24 h and 48 h post-irradiation compared with the CONV-IR group ( t = -2.45, 3.19, 6.51, P < 0.05). At 14 Gy, the MDA-MB-231 cells in the CONV-IR group showed progressively increased mitochondrial and glycolytic metabolism across all time points ( t = 2.48-12.14, P < 0.05). Notably, compared with the CONV-IR group, the MDA-MB-231 cells in the FLASH-IR group exhibited more significantly up-regulated basal respiration, ATP-linked respiration, and non-mitochondrial oxygen consumption ( t = 2.56-6.51, P < 0.05), as well as a higher glycolytic capacity at 24 h post-irradiation ( t = 2.86, P < 0.05). Conclusions:Low-dose (2 Gy) FLASH-IR induces relatively up-regulated proton leak in breast cancer cells MDA-MB-231 at 24 h post-irradiation. In contrast, under high-dose (14 Gy) FLASH-IR, the MDA-MB-231 cells show more pronounced mitochondrial metabolic stress and a higher demand for energy metabolism.

"Upper deficiency leading to vertigo" is one of the representative discussions on deficiency vertigo in Huang Di Nei Jing, which has laid the foundation for the rich development of the theory of "deficiency causing vertigo" in later generations. The brain lymphatic system can remove metabolic wastes and provide nutrients for the brain, which is involved in the development of many brain diseases. This study believes that the broad definition of "upper deficiency leading to vertigo", that is to say, vertigo is triggered by abnormalities in the local physiological functions of the brain orifices, can be used as a platform for the pathogenesis of vertigo. Based on the findings of modern medicine on the lymphoid system, the authors discussed the possible interactions between the lymphoid system, phlegm, blood stasis, deficiency, and other pathological factors of vertigo. β-amyloid, neurotransmitters, inflammatory mediators and other "toxic pathogenic factors" may also be an important cause of vertigo. This article attempted to explain the pathogenesis of "upper deficiency leading to vertigo" with the help of lymphoid system, in order to provide new thinking direction for the development of TCM clinical diagnosis and treatment of vertigo.

Objective To investigate the effects of Caenorhabditis elegans(C.elegans)endogenous U6 promoters on dpy-10 gene editing efficiency.Methods We screened endogenous U6 small nuclear RNA(snRNA)genes of C.elegans from the WormBase database and constructed 14 editing plasmids targeting dpy-10 by replacing the U6r07e5.16 promoter in the pSX524 plasmid(Peft-3::cas9::tbb-2 terminator::U6 r07e5.16::dpy-10 sgRNA)through molecular cloning.Gene editing was performed in wild-type C.elegans using a standardized microinjection protocol.Gene editing efficiency and the high-efficiency gene editing index were quantified based on the screening of dpy-10 mutant phenotypes in the F1 progeny.Results A total of 15 U6 snRNA genes(r07e5.16,f35c11.9,t20d3.13,k09b11.15,k09b11.16,w05b2.8,c28a5.7,f54c8.9,k09b11.11,k09b11.12,k09b11.14,t20d3.12,f54c8.8,f54c8.10,and k09b11.13)were identified from the WormBase database.Based on the editing efficiency and high-efficiency gene editing index,the activity of these promoters was evaluated,and 4 U6 promoters(w05b2.8,c28a5.7,f54c8.9,and k09b11.11)were found to have significantly enhanced gene editing success rates,outperforming other promoters,including U6r07e5.16 and U6k09b11.12,which are commonly used in the C.elegans research community.Notably,the gRNAF+E scaffold did not show superior editing efficiency over the gRNA scaffold when paired with the optimal U6w05b2.8 promoter.Conclusion In this study,U6 promoters that significantly improve gene editing efficiency in C.elegans are identified and the critical role of promoter optimization in CRISPR-Cas9 systems is highlighted.These findings provide a valuable foundation for improving genome editing strategies and offer new ideas for optimizing the CRISPR technology applied in nematode research.
