AIM: To investigate and analyze serum nitric oxide synthase 4(NOX4)and matrix metalloproteinase(MMP)-2 expressions in patients with diabetes mellitus(DM)complicated with neovascular glaucoma(NVG)and their clinical significance.METHODS: A prospective study was conducted on 161 patients with DM complicated with NVG admitted to Handan City Eye Hospital(The Third Hospital of Handan)from June 2020 to June 2023. Based on whether complications occurred 1 a after trabeculectomy in the study group patients, they were divided into a group with good prognosis(n=90)and a group with poor prognosis(n=71). During the same period, 161 patients with chronic angle-closure glaucoma without iris neovascularization were selected as the control group. ELISA method was applied to detect the expression levels of serum NOX4 and MMP-2. ROC curve was plotted to evaluate the diagnostic value and postoperative complication prediction value of NOX4 and MMP-2 in patients with DM complicated with NVG. Pearson method was applied to analyze the correlation of NOX4 and MMP-2 with vascular endothelial growth factor(VEGF)and interleukin-6(IL-6). Multivariate Logistic regression was applied to analyze the influencing factors of postoperative complications in the study group.RESULTS:The general information of the study group and control group of patients is comparable. Compared with the control group, the expression levels of serum NOX4, MMP-2, VEGF, and IL-6 in the study group were significantly increased(P<0.001). According to Pearson analysis, serum NOX4 and MMP-2 levels significantly positively correlated with VEGF and IL-6 levels, respectively(P<0.001). According to ROC curve, the AUC of NOX4 combined with MMP-2 in the diagnosis of DM complicated with NVG was better than that of individual diagnosis of NOX4(Z=3.341, P<0.05)and MMP-2(Z=2.788, P<0.05). The duration of DM, the proportion of people with intraocular pressure >21 mmHg, and the expression levels of NOX4, MMP-2, VEGF, and IL-6 in the poor prognosis group were all higher than those in the good prognosis group(P<0.001). The duration of DM, intraocular pressure >21 mmHg, the levels of NOX4, MMP-2, VEGF, and IL-6 were all risk factors for poor prognosis in DM patients with NVG(P<0.001). According to ROC curve, the combined prediction of NOX4 and MMP-2 for postoperative complications in patients with DM complicated by NVG was superior to the AUC predicted by NOX4(Z=3.727, P<0.05)and MMP-2(Z=2.219, P<0.05), respectively.CONCLUSION:NOX4 and MMP-2 are upregulated in the serum of patients with DM complicated by NVG. Combined detection of these two markers holds significant clinical value for the early diagnosis and prognosis of patients with DM complicated by NVG.

ObjectiveTo investigate the mechanisms by which Bushen Tongluo Jiangzhuo prescription improves renal fibrosis in rats with chronic kidney disease (CKD) through the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsSeventy specific pathogen-free (SPF) Sprague-Dawley (SD) rats were randomly divided into a control group (n=15) and a modeling group (n=55). Rats in the modeling group were administered a 2.5% adenine suspension at a dose of 200 mg·kg-1·d-1 by gavage for 4 weeks to establish a CKD model. Successfully modeled rats were randomly divided into a model group, an irbesartan group (20.25 mg·kg-1·d-1), and Bushen Tongluo Jiangzhuo prescription low-, medium-, and high-dose groups (5.82, 11.64, and 23.28 g·kg-1·d-1, respectively), with 10 rats in each group. Each group was administered an equal volume of physiological saline, the corresponding concentration of irbesartan, or Bushen Tongluo Jiangzhuo prescription by gavage for 12 weeks. Body weight and renal function indices were dynamically monitored. Serum creatinine (SCr), blood urea nitrogen (BUN), urine albumin-to-creatinine ratio (ACR), 24-hour urinary total protein (24 hUTP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) levels were measured using an automatic biochemical analyzer. Renal histopathological changes were observed by hematoxylin-eosin (HE) and Masson staining. Immunohistochemistry (IHC) was used to detect the expression of PI3K, Akt, phosphorylated Akt (p-Akt), and mTOR in renal tissues. Western blot was performed to assess the protein expression of PI3K, p-Akt, Akt, phosphorylated mTOR (p-mTOR), and mTOR in renal tissues. Real-time quantitative polymerase chain reaction (Real-time PCR) was used to determine the mRNA expression levels of PI3K, Akt, and mTOR in renal tissues. ResultsCompared with the model group, rats in the irbesartan group and the low-, medium-, and high-dose Bushen Tongluo Jiangzhuo prescription groups showed significantly decreased levels of SCr, BUN, ACR, 24 hUTP, IL-1β, IL-6, and TNF-α (P<0.01). AST levels were significantly increased (P<0.01), while no significant difference was observed in ALT levels. Histopathological examination revealed that, compared with the model group, renal tubular epithelial cell edema and necrosis and Bowman's capsule dilation were alleviated, inflammatory cell infiltration was reduced, and interstitial and glomerular fibrosis was markedly improved in all treatment groups, with the most pronounced effect observed in the high-dose Bushen Tongluo Jiangzhuo prescription group. Real-time PCR results showed that mRNA expression levels of PI3K, Akt, and mTOR were significantly downregulated in the high-dose group (P<0.01). IHC results demonstrated that PI3K and p-Akt expression levels in renal tissues were significantly decreased in the high-dose group (P<0.01). Western blot analysis further confirmed that the expression levels of PI3K, p-Akt/Akt, and p-mTOR/mTOR were significantly reduced in the high-dose group (P<0.01). ConclusionBushen Tongluo Jiangzhuo prescription improves renal function indices in CKD rats, reduces collagen deposition in renal tissues, and decreases serum inflammatory factor levels. Its protective effect on renal function may be achieved by activating autophagy through downregulation of the PI3K/Akt/mTOR signaling pathway, thereby alleviating renal fibrosis.

To investigate the changes in peripheral blood immune cells before and after the onset of septic shock in patients with malignant tumors, and to analyze the relationship between these immune cells and patient prognosis. A retrospective study was conducted, enrolling perioperative tumor patients who were transferred to the intensive care unit (ICU) due to septic shock at Shanxi Provincial Cancer Hospital between October 2018 and December 2019.Changes in lymphocyte counts and subsets were compared before and after septic shock (measured prior to septic shock onset and within 72 hours after onset).A multivariate Logistic regression model was used to analyze the relationship between these immune indicators and the 28-day mortality risk in tumor patients following septic shock. A total of 47 tumor patients transferred to the ICU due to septic shock were included.There were 32 males and 15 females, with a mean age of (63.9±11.2) years.Gastrointestinal tumors were the most common tumor type (76.60%, 36/47), and abdominal/pelvic infection (65.96%, 31/47) was the primary source of infection.Within 28 days after ICU transfer, 12 patients died and 35 survived. Compared to pre-septic shock levels, lymphocyte counts significantly decreased after septic shock[530(300, 830) cells/μL Perioperative tumor patients experience acute depletion of peripheral blood lymphocyte subsets following septic shock.Among various immune indicators, regulatory T cell count serves as an independent predictor of short-term mortality risk.Evaluating baseline immune function in such patients may help optimize treatment strategies and improve overall prognosis.

This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine (TCM) for gastroesophageal reflux disease (GERD). Studies demonstrate that TCM, based on the "disease-syndrome combination" approach, exhibits multi-target advantages in alleviating symptoms of various GERD subtypes, promoting mucosal repair, regulating emotions, and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy, strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions, promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory, human experience and clinical trial evidence, and optimizing integrated traditional and western medicine models to enhance GERD management.

Employing bibliometric methods and adhering to principles of textual research, this study systematically investigated prescription source, formula name, composition evolution, dose evolution, origin, processing, ancient and modern applications of Xiaofengsan. Xiaofengsan, also known as Renshen Xiaofengsan and Chantui Xiaofengsan, was first recorded in the Taiping Huimin Hejijufang(hereafter referred to as Jufang) of the Southern Song dynasty. The formula composition included Schizonepetae Spica, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Notoptery Rhizoma et Radix, Bombyx Batryticatus, Saposhnikoviae Radix, Poria, Cicadae Periostracum, Pogostemonis Herba, Ginseng Radix et Rhizoma, Magnoliae Officinalis Cortex and Citri Reticulatae Pericarpium, a total of 12 medicinal materials. In terms of the evolution of formula composition, formulas across dynasties largely aligned with those recorded in Jufang, with only minor variations in application. The results of the formula dosage research indicated that one dose of medication in Jufang corresponded to the following modern dosages:Schizonepetae Spica of 82.6 g, Glycyrrhizae Radix et Rhizoma of 82.6 g, Chuanxiong Rhizoma of 82.6 g, Notoptery Rhizoma et Radix of 82.6 g, Bombyx Batryticatus of 82.6 g, Saposhnikoviae Radix of 82.6 g, Poria of 82.6 g, Cicadae Periostracum of 82.6 g, Pogostemonis Herba of 82.6 g, Ginseng Radix et Rhizoma of 82.6 g, Magnoliae Officinalis Cortex of 20.65 g and Citri Reticulatae Pericarpium of 20.65 g, the origins of all the constituent drugs were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The results of the investigation into the decoction method indicated that the aforementioned drugs should be finely ground into powder(pass through the No.5 sieve), and 8.26 g was taken for each dose, which was taken with the clear liquid obtained by steeping tea leaves in boiling water for several minutes. This mixture was administered three times daily, 30 min after meals. The ancient functional indications of this formula mainly involved dispelling wind-heat, eliminating pathogenic factors and regulating the middle Jiao. It primarily treated all wind-heat syndromes manifesting as skin diseases, predominantly affecting the upper body, especially the head and face. The diseases involved in modern applications were mostly dermatological diseases, including urticaria, eczema, atopic dermatitis and others. In this paper, by combing the relevant ancient literature, the key information of Xiaofengsan was textual researched, in order to provide reference for the modern application and development of this formula.

Objective To analyze the influenza-like illness (ILI) data in Ordos City from 2017 to 2023 and conduct nucleic acid detection of the virus to understand the local influenza epidemic situation, and to provide a reliable basis for influenza prevention and control in the city. Methods Real-time quantitative polymerase chain reaction (qPCR) was used to identify virus subtypes in ILI throat swab samples. Comparisons of positive rates were conducted using the chi-square test, with a significance level of α=0.05. Results From 2017 to 2023, a total of 3,283,434 outpatient and emergency visits were recorded at the Ordos City Central Hospital, including 74,159 ILI cases, with an ILI proportion of 2.26%. The majority of ILI cases (74.43%) occurred in children aged 0~14 years old. The overall positive rate of influenza virus nucleic acid detection was 10.87%, with the highest proportion being subtype A (seasonal H3) at 43.03%. The highest detection rate was observed in the 5~14 years age group, with statistically significant differences in positive rates across age groups (χ2=155.638, P<0.001). Influenza peaks occurred mainly from November to March of the following year. From January to April, three types of influenza were prevalent alternately or mixed, while from October to December, subtype A (seasonal H3) predominated. Positive rates varied significantly across months (χ2=250.923, P<0.001). The temporal trends of ILI proportions and PCR-positive rates were consistent. Conclusion Influenza in Ordos City exhibits distinct seasonal and age distribution characteristics, with alternating or mixed circulation of three virus types. Continued efforts are needed to strengthen influenza surveillance, especially the prevention and control of influenza in infants and adolescents.
7.Current status of diagnosis and treatment in patients with high myopia combined with glaucoma
International Eye Science 2026;26(5):800-804
High myopia combined with glaucoma(HMG), as a refractory subtype of glaucoma, poses significant challenges due to overlapping structural alterations of both conditions,leading to difficulties in differential diagnosis and a notably high missed diagnosis rate. Optical coherence tomography(OCT)revealed that rapid thinning of the temporal retinal nerve fiber layer is a key biomarker for the early diagnosis of HMG, and reference values for physiological thinning have been established. In addition, artificial intelligence(AI)-assisted diagnostic systems have demonstrated considerable potential in scenarios such as fundus image analysis and data interpretation. Global collaborative initiatives on HMG are currently constructing multicenter databases to support the training and validation of AI models.In terms of treatment, the strategy for intraocular pressure control needs to be further optimized,including setting lower target intraocular pressure, paying attention to medication specificity, while emphasizing neuroprotection and lifestyle interventions. Innovative treatments, including stem cell therapy, have progressed to phase II clinical trials, with some patients exhibiting measurable improvements in visual acuity. Furthermore, individualized management based on disease stratificationis is still required. Future developments are expected to focus on precision medicine, early screening programs, and interdisciplinary collaboration, with the goal of improving visual outcomes in patients with HMG.

OBJECTIVE To analyze the impact of the diagnosis-related groups (DRG) payment reform on the length of stay and medical costs in patients with chronic obstructive pulmonary disease (COPD) in Kashgar region, aiming to provide localized empirical evidence for the optimization of regional medical insurance payment methods. METHODS Based on the inpatient settlement database of the Xinjiang Uygur Autonomous Region Healthcare Security Administration, settlement data of COPD inpatients from 17 medical institutions in Kashgar region between January 1, 2022, and December 31, 2024, were extracted. The overall changes in patients’ length of stay and costs were compared before and after the reform. Subsequently, interrupted time series analysis (ITSA) was employed to explore the impact of the DRG payment reform on these variables. RESULTS Following the reform, both the average length of stay and various cost decreased significantly compared to the pre-reform period ( P <0.001). At the overall sample level, the average length of stay, average total cost, average drug cost, average medical service cost, and average examination cost per admission all demonstrated significant long-term downward trends after the reform ( P <0.05). However, the decrease in average out-of-pocket costs and the increase in average consumable costs per admission were not statistically significant ( P >0.05). In tertiary medical institutions, the average length of stay and all categories of costs (except average consumable costs per admission) exhibited significant long-term upward trends after the reform ( P <0.05); conversely, in secondary and lower-level medical institutions, the average length of stay, average total cost, average drug cost, average medical service cost, and average examination cost per admission showed significant long-term downward trends ( P <0.05). CONCLUSIONS The DRG payment reform has achieved an overall effect of reducing the length of stay and controlling costs in COPD patients from Kashgar region. However, the effects vary across different levels of medical institutions: secondary and lower-level institutions show a long-term downward trend in length of stay and costs, whereas tertiary institutions exhibit a long-term upward trend. Furthermore, patients’ out-of-pocket financial burden does not show significant improvement.

[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.

ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.
