AIM: To investigate the influence of pterygium thickness and area on corneal refractive status.METHODS: Prospective longitudinal study. A total of 60 cases(60 eyes)of pterygium patients admitted to our hospital from January 2024 to September 2024 were randomly selected. All patients underwent pterygium excision combined with pedicle conjunctival flap transplantation for treatment. Optical coherence tomography(OCT)was used to measure the preoperative thickness of patient's pterygium, and a digital slit lamp microscope was used to measure the area of pterygium. The corneal refractive status(degree of corneal astigmatism and average curvature)and changes in uncorrected visual acuity of patients before surgery, 1 d, 1, and 3 mo after surgery were compared. The relationship between preoperative thickness and area of pterygium in patients and corneal refractive status indicators at different postoperative time points were analyzed, and Logistic regression was used to analyze the impact of pterygium thickness and area on postoperative visual improvement in patients.RESULTS: All patients completed follow-up after surgery for 3 mo. At 3 mo after surgery, visual acuity improved in 21 eyes(35%). The results of bivariate Pearson correlation analysis showed that the thickness and area of pterygium positively correlated with the degree of corneal astigmatism and uncorrected visual acuity before surgery and 1 d, 1, and 3 mo after surgery(all P<0.05), and negatively correlated with the average corneal curvature before surgery and 1 d, 1, and 3 mo after surgery(all P<0.05). Logistic regression analysis showed that the thickness and area of pterygium before surgery, high degree of corneal astigmatism, and low uncorrected visual acuity(large LogMAR value)were all risk factors for poor postoperative visual improvement in patients(OR>1, P<0.05). The large average corneal curvature before surgery was a protective factor for poor postoperative visual improvement in patients(OR<1, P<0.05).CONCLUSION: The increase in thickness and area of pterygium can, to some extent, improve corneal astigmatism, reduce the average curvature of the cornea, and affect postoperative visual recovery.

ObjectiveTo explore the changes in color, odor and chemical components during wine-processing of Chuanxiong Rhizoma(CR), identify differential markers, and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis(PLS-DA), principal component analysis(PCA), discriminant factor analysis(DFA) and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models, and differential components were screened out based on variable importance in the projection(VIP) value1. Then, high performance liquid chromatography(HPLC) was employed to detect the content changes of four components(ferulic acid, senkyunolide I, senkyunolide A and ligustilide) during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L*(brightness value), a*(red-green value) and b*(yellow-blue value). Based on chromaticity differences, the color reference ranges were established for moderately processed CR, including L* of 46.75-48.24, a* of 5.37-6.07 and b* of 20.32-21.70. In odor analysis, DFA revealed significant differences among processing stages, and 11 odor markers were identified, with four differential markers(4-hydroxy-3-butylphthalide, isopropyl butyrate, L-limonene and 1-methoxyhexane) based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection, with discrimination accuracy rates of 92.4% and 93.272% for color and odor, respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages, and four differential components were screened out, providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

ObjectiveTo investigate the possible mechanism of Jishe Qushi Capsule (脊蛇祛湿胶囊, JQC) in treating rheumatoid arthritis (RA) from the perspective of macrophage polarization mediated by neutrophil extracellular traps (NETs). MethodsTwenty-four female SD rats were randomly divided into four groups, blank control group, model group, JQC group, and peptidylarginine deiminase 4 (PAD4) inhibitor group with 6 rats in each group. All groups but the blank control group were subjected to the induction of collagen-induced arthritis (CIA). After successful model establishment, rats in the JQC group received intragastric administration of JQC 1.47 g/kg daily; rats in the PAD4 inhibitor group received intraperitoneal injections of the PAD4 inhibitor 4 mg/kg weekly. Rats in the blank, model, and PAD4 inhibitor groups received 2 ml of pure water daily by gavage. All treatments lasted 4 weeks. Joint lesions of each group were assessed on day 7, 14, 21, 28, and 35 after model establishment, and arthritis index (AI) scores were recorded. At 24 h after the final administration, histopathology of knee joints, including HE staining, safranin O-fast green staining, and TRAP staining, was performed. Flow cytometry was used to detect the counts of M1 and M2 macrophages in peripheral blood. ELISA was used to determine serum levels of TRACP, NETs, TNF-α, IL-1β, and iNOS. Western Blotting and qRT-PCR were used to measure MPO, NE, RANKL, OPG, and p65 protein and mRNA expression in knee cartilage tissue. ResultsCompared with the blank control group, the model group showed increased AI scores (P<0.05), marked synovial inflammatory infiltration, angiogenesis, and bone-cartilage destruction, increased TRAP-positive osteoclasts, increased M1 macrophages and decreased M2 macrophages, elevated serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), elevated MPO, NE, RANKL, and p65 protein/mRNA expression and decreased OPG protein/mRNA expression in knee cartilage tissue (P<0.05). Compared with the model group, the JQC group exhibited improved synovial inflammation, angiogenesis, and bone-cartilage damage, reduced AI scores on day 21, 28, and 35, decreased osteoclast counts, decreased M1 macrophages and increased M2 macrophages, reduced serum TRACP, NETs, TNF-α, IL-1β, and iNOS (P<0.05), decreased MPO, NE, RANKL, and p65 protein/mRNA expression and increased OPG expression (P<0.05). Compared with the PAD4 inhibitor group, the JQC group showed significantly lower AI scores, reduced M1 macrophages, increased M2 macrophages (P<0.05), reduced serum TRACP, TNF-α, IL-1β, and iNOS, decreased MPO, RANKL, and p65 expression, and increased OPG levels (P<0.05). ConclusionThe therapeutic mechanism of JQC for RA may involve inhibition of NETs formation, downregulation of the RANKL/NF-κB signaling pathway, and regulation of macrophage M1/M2 polarization imbalance, thereby suppressing osteoclastogenesis and inflammatory bone destruction.

Diabetic Peripheral Neuropathy (DPN) is one of the most common and harmful complications of type 2 diabetes. DPN's pathogenesis include high blood sugar-induced oxidative stress, inflammation, and mitochondrial dysfunction. These factors are combined to damage nerve fibers, leading to sensory issues, pain, and numbness. Through a coordinated effect, these factors trigger nerve fiber damage and lead to sensory abnormalities, pain and numbness in limbs, and other symptoms, seriously restricting patients' activities of daily living and mobility. Recent research highlights that cellular senescence plays a critical role in DPN. Cellular senescence is manifested by the loss of cell proliferation ability, and further aggravates nerve damage via oxidative stress, mitochondrial dysfunction, autophagy impairment, inflammatory reaction, and other mechanisms, accelerating DPN occurrence and progression. In terms of medical treatment, current methods focus on blood sugar control, pain relief medicine, and microcirculation improvement, while no therapy has been developed based on cellular senescence. In contrast, traditional Chinese medicine (TCM) shows a unique advantage in DPN prevention and treatment via cellular senescence modulation. TCM emphasizes a holistic approach, as well as syndrome differentiation and treatment, effective in anti-aging and nerve damage repair. Recent studies show that TCM active ingredients, including puerarin, ginsenosides, and berberine, can reduce inflammation, oxidative stress, and apoptosis via signaling pathway regulation, thereby slowing cellular senescence to alleviate nerve damage. Furthermore, TCM compounds such as Buyang Huanwutang, Taohong Siwutang, and Huangqi Guizhi Wuwutang exert synergistic effects on cellular senescence-related pathways to improve nerve health and reduce DPN clinical symptoms. Therefore, this paper reviews the literature related to the interaction between cellular senescence and DPN from the perspective of cellular senescence, summarizing the mechanism of DPN and TCM intervention strategies.

ObjectiveTo evaluate the clinical efficacy of Huayu Tongluo Formula (化瘀通络方, HTF) in patients with mid-stage diabetic kidney disease of blood stasis syndrome and explore its potential mechanisms. MethodsA multi-center, randomized, double-blind, placebo-controlled clinical trial was conducted. Ninety patients of mid-stage diabetic kidney disease of blood stasis syndrome were divided into a control group of 46 cases and a treatment group of 44 cases. Both groups received conventional western medicine treatment, the treatment group additionally taking HTF, while the control group taking a placebo of the formula. The treatment was administered once daily for 24 weeks. The primary outcomes included 24-hour urine total protein (24 h-UTP), serum albumin (Alb), glycated hemoglobin (HbA1c), and serum creatinine (Scr).The secondary outcomes included changes in levels of endothelin-1 (ET-1), nitric oxide (NO), vascular endothelial growth factor (VEGF), and traditional Chinese medicine (TCM) syndrome scores before and after treatment. Clinical efficacy was evaluated based on TCM syndrome scores and overall disease outcomes. Adverse reactions and endpoint events were recorded. ResultsIn the treatment group after treatment, 24 h-UTP, ET-1, and VEGF levels significantly decreased (P<0.05), Alb and NO levels significantly increased (P<0.05); while the TCM syndrome scores for edema, lumbar pain, numbness of limbs, dark purple lips, dark purple tongue or purpura, and thin, rough pulse all significantly decreased (P<0.05). In the control group, no significant changes were observed in any of the indicators after treatment (P>0.05).Compared with the control group, the treatment group showed significant reductions in 24 h-UTP, ET-1, and VEGF levels, and increases in Alb and NO levels (P<0.05). The TCM syndrome scores for edema, lumbar pain, dark purple tongue or purpura, and thin, rough pulse were all lower in the treatment group than in the control group (P<0.05). The total effective rate of TCM syndrome in the treatment group was 59.09% (26/44), and the overall clinical effective rate was 45.45% (20/44). In the control group, these rates were 15.22% (7/46) and 8.7% (4/46), respectively, with the treatment group showing significantly better outcomes (P<0.05). A total of 7 adverse events occurred across both groups, with no significant difference (P>0.05). No endpoint events occurred during the study. ConclusionOn the basis of conventional treatment of Western medicine, HTF can further reduce urinary protein levels and improve clinical symptoms in patients with mid-stage diabetic kidney disease of blood stasis syndrome. The mechanism may be related to its effects on endothelial function.

ObjectiveTo observe the intervention effect of Fufang Kangjiaolv capsules on anxiety-like behaviors in the rat model of chronic restraint stress (CRS) and explore the mechanism underlying the anti-anxiety effect via the microbiota-gut-brain axis. MethodsRats were assigned into blank, model, positive drug (diazepam, 1 mg·kg-1), and low-, medium-, and high-dose (0.75, 1.5, 3 g·kg-1, respectively) Fufang Kangjiaolv capsules groups. After 14 days of administration, the elevated plus maze test, open field test, light and dark box test, and marble burying test were performed. Hematoxylin-eosin staining was employed to observe the pathological changes in the hippocampus and colon of rats, and Nissl staining was conducted to observe the damage of hippocampal neurons. The gut microbiota was analyzed by 16S rRNA gene sequencing. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of zonula occludens-1 (ZO-1) and occludin in the colon of rats. The levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in the colon, serum, and hippocampus were determined by enzyme-linked immunosorbent assay. Western blot was employed to determine the protein levels of ZO-1, occludin, nuclear factor-κB p65 (NF-κB p65) in the colon tissue and NF-κB p65 and brain-derived neurotrophic factor (BDNF) in the hippocampal tissue. ResultsCompared with the blank group, the model group showed reductions in the time and frequency ratio of rats entering the elevated plus maze, the time and frequency of rats entering the central area of the open field, the time of entering the open box, the times of passing through the light and dark box, and the number of unburied beads (P<0.05, P<0.01). Compared with the model group, Fufang Kangjiaolv capsules ameliorated the anxiety of the model rats to varying degrees, and the high-dose group had the best effect, with increases in the proportions of time and frequency of rats entering the open arm in the elevated plus maze (P<0.05), the number of rats entering the central area in the open field (P<0.05), the time of entering the open box, the times of passing through the light and dark boxes, and the number of unburied beads (P<0.01). Moreover, the high-dose group showed alleviated pathological damage of hippocampal neurons and colon. The results of 16S rRNA gene sequencing showed that the model group had increased relative abundance of Firmicutes, Deferribacterota, Romboutsia, and Phascolarctobacterium, while it had decreased relative abundance of Bavcteroidota and Lactobacillus. The drug administration groups showed increased relative abundance of Bavcteroidota, Bacteroides, norank f norank o Clostridia UCG-014, and Blautia and decreased relative abundance of Firmicutes and Deferribacterota. Compared with the blank group, the model group showed down-regulated protein and mRNA levels of ZO-1 and occludin in the colon (P<0.01), elevated levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated protein level of NF-κB p65 in the colon and hippocampus (P<0.01), and down-regulated protein level of BDNF in the hippocampus (P<0.05). Compared with the model group, high-dose Fufang Kangjiaolv capsules up-regulated the mRNA levels of ZO-1 and occludin in the colon (P<0.01), lowered the levels of TNF-α, IL-6, and IL-β in the colon, serum, and hippocampus (P<0.01), up-regulated the protein levels of ZO-1 (P<0.01) and occludin (P<0.05) in the colon, down-regulated the protein level of NF-κB p65 in the colon and hippocampus (P<0.05), and up-regulated the protein level of BDNF in the hippocampus. ConclusionFufang Kangjiaolv capsules can reduce the anxiety-like behaviors in the rat model of CRS by regulating the gut microbiota disturbance, up-regulating the expression of tight junction proteins in the colon, repairing intestinal mucosal mechanical barrier, and down-regulating NF-κB/BDNF signaling pathway, thereby reducing peripheral and central inflammation. This study proves the hypothesis that Fufang Kangjiaolv capsules play an anti-anxiety role via the microbiota-gut-brain axis, providing a new idea for further research.

ObjectiveTo systematically organize the relevant research on the treatment of uterine fibroids with Xiaojie'an capsules through clinical evidence evaluation and comprehensive value analysis in the "6+1" dimension,highlighting the efficacy and characteristics of Xiaojie'an capsules. MethodsBased on evidence-based medicine,epidemiology,pharmacoeconomics,health technology assessment (HTA), and other methodologies,this study adopted qualitative and quantitative evaluation methods. Through a questionnaire survey,official website data information,published literature, and secondary evaluation of real world data,a total of "6+1" dimensions were used to build an evaluation system for the safety,effectiveness,economy,innovation,suitability,accessibility of Chinese patent medicines, and characteristics of traditional Chinese medicines. Results① Safety:From January 2009 to March 2023,the National Adverse Drug Reaction Monitoring Center reported 159 cases (248 cases) of general adverse reactions and four cases of serious adverse reactions to Xiaojie'an capsules,all of which were classified as general adverse reactions after expert judgment. Through literature search,a total of 6 865 patients were treated with Xiaojie'an capsules,of which 26 articles reported adverse reactions to Xiaojie'an capsules,resulting in a total of 244 adverse reactions. The clinical manifestations of adverse reactions to Xiaojie'an capsules include nausea,vomiting,stomach discomfort,diarrhea,rash,itching,dizziness,headache,insomnia,etc. The prognosis was good, and the drug surveillance system was sound. Based on the evaluation of known risks and sufficient evidence,in terms of known risk assessment, according to the monitoring results of the spontaneous reporting system (SRS), there were four cases of serious adverse reactions to Xiaojie'an capsules. After expert discussion, the four cases of serious adverse reactions were finally judged as general adverse reactions, and the known risks were considered to be small in combination with the known risk evaluation criteria. According to the types of studies carried out on Xiaojie'an capsules (randomized controlled trial and its systematic review, SRS data analysis, real world human experience studies, and non-clinical safety studies) and the evaluation criteria of sufficient evidence, it was considered that Xiaojie'an capsules had sufficient evidence. The safety evidence of this variety was sufficient, and the result was confirmed. ② Effectiveness: Meta-analysis results showed that the combination of Xiaojie'an capsules and Mifepristone tablets had better clinical efficacy compared to Mifepristone tablets alone and had a better effect in reducing the maximum uterine fibroid volume. Due to limitations and imprecision caused by downgrading factors,the quality of evidence was evaluated as Grade C. Based on comprehensive effectiveness evidence and value evaluation,the effectiveness evidence of this variety was relatively sufficient, and the results were clear ③ Economy:The economic evaluation results showed that treating one more patient with uterine fibroid required an additional cost of 5 438.57 yuan by using the combination of Xiaojie'an capsules and Mifepristone tablets,which was lower than the patient's willingness to pay (36 883 yuan according to 2022 National Bureau of Statistics data). This suggested that compared with using Mifepristone tablets alone,the combination of Xiaojie'an capsules and Mifepristone tablets had a certain economy. The sensitivity analysis results were relatively robust,indicating that this variety had good economy ④ Innovation:Currently,most traditional Chinese medicine treatments for uterine fibroids advocate the method of attacking evil,which can easily harm the body. However,Xiaojie'an capsules not only soften and disperse nodules but also balance supporting the body and supplementing deficiency. The comprehensive evaluation showed sufficient evidence of the innovation of this variety,and the results were confirmed. ⑤ Suitability: The service information of Chinese patent medicines derived from the drug was complete,and the questionnaire survey results showed that the drug was suitable for clinicians,nurses,pharmacists, and patients in multiple dimensions such as individual compliance,system, and management. The comprehensive evaluation of the suitability of the product had sufficient evidence and clear results. ⑥ Accessibility:The daily cost of Xiaojie'an capsules was 16.97 yuan,and the treatment cost was 407.16 yuan. It was affordable for urban residents and rural residents and was available for sale in 23 provinces, cities,municipalities,and autonomous regions across the country. The medicinal resources were abundant and sustainably supplied,and there was sufficient evidence of accessibility with clear results. ⑦ Characteristics of traditional Chinese medicine:Xiaojie'an capsules were derived from the classic Dai medicine formula of Dr. CHEN Benshan,a renowned Dai doctor,and they have been clinically used for over 20 years. Dai medicine originated from Xishuangbanna,Yunnan province,with the core theory of "four pagodas and five elements". The comprehensive evaluation showed that this variety exhibited significant characteristics of traditional Chinese medicine. ⑧ Comprehensive evaluation of clinical value:Based on the "6+1" dimensions mentioned above,combined with the multi-criteria decision analysis (MCDA) model and calculations using CSC v2.0 software,the results showed that there was sufficient evidence for the clinical value of Xiaojie'an capsules,and the results were clear. ConclusionThe comprehensive evaluation of Xiaojie'an capsules has sufficient evidence of safety and innovation,and the results are confirmed. The evidence of effectiveness,suitability,and accessibility is relatively sufficient,with clear results. The economy is good,and the characteristics of traditional Chinese medicine are prominent. The comprehensive evaluation of clinical value believes that there is sufficient evidence of the clinical value of Xiaojie'an capsules,and the results are clear. In the future,it is recommended to focus on clinical value, conduct high-quality and effective research that is in line with the characteristics of traditional Chinese medicine, and improve acute toxicity testing to provide a scientific and objective basis for clinical efficacy and safety research.

AIM: To investigate the impact of corneal fluorescein sodium(NaF)staining on the examination results of iTrace visual function analyzer(iTrace).METHODS: Prospective cohort study. Totally 100 patients(100 eyes)with ametropia who visited the outpatient department of Anhui Eye Hospital from April to November 2024 were recruited. They were divided into an experimental group and a control group, with 50 patients(50 eyes, and only the right eyes were selected for inclusion)in each group. In the experimental group, corneal staining was performed using fluorescein sodium staining test strips, while in the control group, 1 drop of 0.9% normal saline was instilled into the eyes. The iTrace examination was conducted before the intervention and at 5, 10, and 20 min after the intervention. The total corneal higher-order aberrations, spherical aberration, coma aberration, trefoil aberration, best sphere value(RO value), asphericity factor(Q value), and corneal vertical refractive power difference(IS value)at each time of examination were recorded and compared.RESULTS: There was no statistically significant difference in the baseline levels between the two groups(all P>0.05). Intra-group comparison revealed that the total higher-order aberrations, spherical aberration, coma aberration, and trefoil aberration measured 5 min after NaF staining in the experimental group were significantly increased compared with those before staining(all P<0.05). Inter-group comparison showed that the changes(differences from the baseline)in the total corneal higher-order aberrations, spherical aberration, coma aberration, and trefoil aberration measured by iTrace 5 min after the intervention in the experimental group were significantly greater than those in the control group(all P<0.05). There was no statistically significant difference in the changes(differences from the baseline)of various iTrace parameters measured at 10 and 20 min after the intervention between the two groups(all P>0.05). There was no statistical significance in the RO value, Q value, and IS value in the two groups(all P>0.05).CONCLUSION: Corneal NaF staining can cause a short-term increase in the wavefront aberration values(total corneal higher-order aberrations, spherical aberration, coma aberration, trefoil aberration)measured by iTrace, and it gradually disappears with the passage of time. However, it has no impact on the measurement of corneal topography parameters(RO value, Q value, IS value).

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams (FHTs) for long-term medication therapeutical management (MTM) in stroke patients, and empirically evaluate the service model. METHODS A pharmacist team, jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University (hereinafter referred to as “our hospital”), developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design, 170 stroke patients discharged from our hospital (July 2022-December 2023) and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group (88 cases) and control group (82 cases) according to random number table. The control group received routine FHTs care (without pharmacist involvement in the team collaboration), while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework, dynamic medication adherence management, medication safety monitoring, a home medication assessment system, and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention, involving medication adherence (adherence rate, adherence score), compliance rates for stroke recurrence risk factors [blood pressure, low-density lipoprotein cholesterol (LDL-C)], and incidence of adverse drug reactions (ADR). RESULTS After 12 months, the trial group exhibited significantly higher medication adherence rates, improved adherence scores, higher compliance rates for blood pressure and LDL-C targets compared to the control group (P<0.05). The incidence of ADR in the trial group (4.55%) was significantly lower than that in the control group (8.11%), though the difference was not statistically significant (P> 0.05). CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence, offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.
