ObjectiveTo evaluate the efficacy and possible mechanism of Wei's Huoxue Tongluo Formula （韦氏活血通络方，WHTF） in treating atrophic-stage non-arteritic anterior ischemic optic neuropathy （NAION） with qi deficiency and blood stasis. MethodsA total of 82 atrophic-stage NAION patients with qi deficiency and blood stasis were randomly divided into a treatment group and a control group， with 41 cases in each group. The treatment group was given oral administration of WHTF twice a day plus acupoint injection of distilled water 2 ml at Taiyang （EX-HN5） once daily， while the control group received injection of compound anisodine injection 2 ml at Taiyang （EX-HN5） once daily and oral administration of WHTF placebo twice a day. Both groups received treatment for a course of 14 days. The best-corrected visual acuity （BCVA）， optic disc perfusion density （PD）， flux index （FI）， macular superficial PD， vascular density （VD）， and traditional Chinese medicine （TCM） syndrome scores were compared between groups before treatment and on day 7 and day 14 of treatment. Additionally， mean defect （MD） and mean sensitivity （MS） of visual fields were measured before treatment and on day 14， along with safety evaluation. ResultsAfter treatment， both groups showed significant improvement in BCVA， visual field MD and MS， and TCM syndrome scores （P＜0.05 or P＜0.01）. On day 14 of treatment， the TCM syndrome score in the treatment group was significantly lower than that in the control group （P＜0.05）. There was no significant improvement in optic disc PD and FI， and macular superficial PD and VD after treatment in either group （P＞0.05） except that on day 7 the macular superficial foveal PD in the control group was significantly better than that in the treatment group （P＜0.05）. During the treatment period， no serious adverse events occurred in either group. ConclusionWHTF can improve the visual function indicators including visual acuity and visual field， as well as TCM syndrome scores in atrophic-stage NAION patients with qi deficiency and blood stasis. It shows clinical safety， although it does not appear to have a significant effect on optic disc or macular blood flow.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

A retrospective investigation was conducted to analyze the occupational exposure history, clinical manifestations, laboratory tests, imaging findings, and diagnosis and treatment of two cases of sequential latent occupational acute organotin poisoning. Both patients were successively employed in the same enterprise, engaged in crushing of waste polyvinyl chloride plastics, and thus potentially exposed to organotin hazards. Within several days of employment, both patients developed discomfort symptoms, and central nervous system impairment was observed, including short-term memory loss, slow response, and cognitive dysfunction. Hypokalemia was detected in both cases. Cranial magnetic resonance imaging showed abnormalities (multiple ischemic lesions in the bilateral frontal and parietal lobes), and urinary tin was positive. Symptoms relieved in both patients after treatments with tin-exclusion, potassium supplementation, and neurotrophic treatment. Based on the GBZ 26-2007 Diagnostic Criteria of Occupational Acute Trialkyltin Poisoning, and combined with worksite survey of occupational health and exclusion of cerebrovascular disease, viral encephalitis, and autoimmune encephalitis and other neurological disorders, both patients were diagnosed with mild occupational acute trialkyltin poisoning. Sequential latent occupational acute organotin poisoning is prone to misdiagnosis, with great difficulty in etiological identification. Comprehensive assessment of occupational exposure history and biomarker testing are essential for differential diagnosis. Early recognition and intervention improve prognosis, highlighting the need for strengthened occupational health supervision and protection in high-risk work posts.

Objective:To investigate the effects of dexmedetomidine (Dex) combined with propofol or cyclopropofol on postoperative stress in laparoscopic ovarian cancer surgery.Methods:A total of 120 ovarian cancer patients who underwent laparoscopic radical resection of ovarian cancer in the Second People′s Hospital of Hengshui from January 2022 to December 2023 were selected and divided into observation group and control group by random number table method, with 60 cases in each group. The control group was given Dex combined with propofol for compound anesthesia, and the observation group was given Dex combined with cyclopropofol for compound anesthesia. The perioperative indicators and intraoperative opioid dosage were compared between the two groups. The heart rate (HR) and mean arterial pressure (MAP) were compared at 3 min after entering the operating room (T 1), intubation (T 2), skin incision (T 3), extubation (T 4) and leaving the operating room (T 5). The Ramsay Sedation Scale (RSS) scores at T 1, T 2, T 3, T 4 and Prince-Henry scores at 2, 6, 12, 24 h after operation were compared. The serum levels of prostin E 2 (PGE 2) and cortisol (Cor) 1 day before operation and 12, 24, 48 h after operation, as well as the incidence of adverse events during treatment were compared between the two groups. Results:The anesthesia recovery time in the observation group was significantly shorter than that in the control group, and the intraoperative dosages of sufentanil and remifentanil were significantly less than those in the control group (all P<0.05). Compared with T 1, there were no significant differences in HR and MAP at T 2, T 3, T 4 in the observation group (all P>0.05); the HR and MAP at T 2, T 3, T 4 in the control group were significantly different from those at T 1 (all P<0.05), and the HR and MAP at T 2, T 3, T 4, T 5 in the observation group were lower than those in the control group (all P<0.05). The RSS scores at T 2, T 3 and T 4 in the observation group were significantly higher than those in the control group (all P<0.05). The Prince-Henry scores at 2, 6, 12, 24 h after operation in the observation group were significantly lower than those in the control group (all P<0.05). The serum PGE 2 and Cor levels at 12, 24 and 48 h after operation in the observation group were significantly lower than those in the control group (all P<0.05). The total incidence of postoperative adverse events in the observation group was 18.33%(11/60), lower than 23.33%(14/60) in the control group ( P<0.05). Conclusions:Compared with Dex combined with propofol, Dex combined with cyclopropofol for compound anesthesia can reduce postoperative stress response in laparoscopic ovarian cancer surgery, improve intraoperative sedation and postoperative analgesia, stabilize hemodynamics, and has good safety.

Objective To investigate cortical morphological changes and structural covariance network(SCN)topological features in patients with visuospatial neglect(VSN)after stroke.Methods A retrospective analysis was conducted on acute stroke patients admitted consecutively to the Department of Rehabilitation Medicine,Xuanwu Hospital,Capital Medical University,from December 2023 to February 2025.General and clinical data were collected and compared,including age,sex,stroke type(hemorrhagic or ischemic),and time from stroke onset to first brain MRI.All patients were assessed for VSN using the line bisection task,line cancellation test,and star cancellation test.Patients with VSN were assigned to the VSN group,and those without VSN to the non-VSN group.Brain MRI was used to collect patients' brain structural images.T1-weighted MRI data were processed using Freesurfer for whole-brain segmentation.Based on the Desikan-Killiany atlas,the cortex was parcellated into 68 regions per hemisphere,total intracranial volume and cortical parameters were extracted,including cortical area(CA),mean cortical curvature(CC),cortical thickness(CT),and cortical volume(CV).A region-specific asymmetry index(AI)was calculated for cortical parameters of each brain regions using(left-right)/(left+right)to assess cortical lateralization.Analyze the SCN of each cortical parameters through covariance matrix to reflect covariation pattern of each brain region's structural morphological alternations.SCN were constructed separately for each cortical parameter based on inter-regional Pearson correlation coefficients(absolute values),with intracranial volume,age,and sex controlled via linear regression.The resulting 68×68 SCN matrices were transformed into binary networks across a sparsity range of 0.1 to 0.4(in 0.01 steps),and graph theoretical analysis were performed.Permutation tests were used to compare the global and local graph theoretical metrics of cortical SCN under each cortical parameters with different sparsity.Global metrics included clustering coefficient,path length,small-worldness parameters(normalized clustering coefficient[Gamma],normalized path length[Lambda],and small-world index[Sigma]),global efficiency,and average local efficiency.Local metrics included nodal degree,betweenness centrality,and nodal efficiency.Results(1)A total of 109 acute stroke patients were included(81 males,28 females,aged 30-80 years,mean[64±9]years),with 54 in the VSN group and 55 in the non-VSN group.No significant differences were found in age,sex,stroke type,or time from stroke onset to MRI between two groups(all P＞0.05).(2)Comparison of cortical features(of different brain regions)between two groups showed significantly larger CA in the right insular surface area in the VSN group(2 466.50[2 143.75,2 662.50]mm2 vs.2 128.00[1 961.00,2 479.00)]mm2,P=0.037).No significant differences were observed in other regions or metrics(all P＞0.05).The VSN group has significantly lower AI values for CT in the right isthmus cingulate gyrus(-0.01[-0.05,0.03]vs.0.02[-0.01,0.06],P=0.028)and postcentral gyrus(-0.02[-0.04,0.00]vs.0.00[-0.02,0.02],P=0.026).No significant AI differences were observed in other regions or metrics(all P＞0.05).(3)For global network metrics:in the CA-based VSN,compared with the non-VSN group,Sigma values were significantly higher in the VSN group across multiple sparsity thresholds and at the average sparsity level(P＜0.01).In the CT-based SCN,Lambda values were significantly higher in the VSN group at most sparsity thresholds and at the average level(P=0.004).In the CC-based SCN,clustering coefficient and average local efficiency were significantly lower in the VSN group across most sparsity thresholds and average sparsity(P＜0.01).No significant differences were found in global metrics within the CV-based SCN.(4)For local metrics:in the CV-based SCN,compared with the non-VSN group,the VSN group showed significantly lower nodal efficiency in the left inferior temporal gyrus at most sparsity thresholds and at the average level(0.35[0.29,0.50]vs.0.65[0.51,0.72],P＜0.01).No significant differences in local metrics were observed in other SCN between the two groups.Conclusions Patients with VSN exhibit abnormal cortical morphology and SCN topology,characterized by reduced overall integration efficiency and weakened local connectivity,alongside enhanced small-worldness and possible compensatory reorganization.The conclusions of this study require further validation in multicenter,large-scale,prospective studies.

Objective To investigate the clinical application value of the combined detection of fecal syndecan 2(SDC2)and tissue factor pathway inhibitor 2(TFPI2)gene methylation in the diagnosis of colorectal cancer and advanced adenoma.Methods 124 pa-tients with colorectal lesions,including 43 colorectal cancer,52 advanced adenoma,and 29 non-advanced adenoma,and 46 patients with other gastrointestinal diseases such as colorectal inflammatory diseases,ulcers,etc.,who visited 5 hospitals in Zhengzhou from 2020 to 2023 were enrolled as the disease group.In addition,78 healthy individuals who underwent physical examinations in the same period were selected as the healthy control group.Their fecal samples were collected before undergoing colonoscopy,and the methyla-tion levels of SDC2 and TFPI2 genes were detected using the quantitative methylation-specific PCR(qMSP).Results The positive rates of the combined detection of SDC2 and TFPI2 gene methylation in the colorectal cancer group and advanced adenoma group(95.34％and 88.46％)were significantly higher than those in the non-advanced adenoma group(48.27％,x2=18.75/13.63,P＜0.05)and healthy controls(3.84％,x2=96.38/91.54,P＜0.05).In the colorectal cancer group,the postoperative positive rate of the combined detection in 34 patients with positive methylation of SDC2 and TFPI2(5.88％)was significantly lower than the preoperative positive rate(95.34％,x2=54.74,P＜0.05).Moreover,the mean Ct values of methylation of SDC2 and TFPI2 genes(32.38±3.72 and 31.85±3.21)in the colorectal cancer group were significantly lower than that in the advanced adenoma group(35.07±3.09 and 34.96±2.78,t=3.84 and 5.05,P＜0.05).The analysis results of the ROC curve showed that the sensitivities of SDC2,TFPI2,and their combination detection in the diagnosis of colorectal cancer were 86.40％,88.37％,and 89.35％,respectively,while in differenti-ating advanced adenoma they were 73.52％,66.73％,and 80.15％,respectively.The combined detection of SDC2 and TFPI2 in differ-entiating colorectal cancer and advanced adenoma achieved the highest diagnostic efficacy(AUCROC=0.889 and 0.738,respectively).Conclusion The combined detection of methylation of SDC2 and TFPI2 genes in fecal samples has high diagnostic value for colorectal cancer and advanced adenomas,and also has certain clinical application value for the progression and postoperative monitoring of the disease.

Objective:To investigate the impact of Wenyang Ligong Decoction on pregnancy outcomes after transcervical resection of adhesions (TCRA) in patients with intrauterine adhesions (IUA).Methods:A retrospective cohort study was conducted to collect clinical data from 151 patients with IUA who underwent TCRA in the Reproductive Medicine Department of the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine between January 2020 and January 2023. Patients were divided into a Traditional Chinese medicine (TCM) group (79 patients) and a control group (72 patients) based on whether they received Wenyang Ligong Decoction after TCRA. The TCM group received estrogen and progesterone sequential therapy post-surgery, combined with Wenyang Ligong Decoction for 2-3 menstrual cycles. The control only received sequential treatment with estrogen and progesterone.Pregnancy outcomes one year after surgery were compared between the two groups. After adjusting for confounding factors using multivariate Cox regression analysis, the effect of Wenyang Ligong Decoction on pregnancy outcomes after TCRA in patients with IUA was observed.Results:The live birth rate [54.43%　(43/79)], the ongoing pregnancy rate [56.96% (45/79)], and the clinical pregnancy rate [52.03% (49/79)] were higher in the TCM group than in the control [26.39% (19/72), P<0.001; 30.56% (22/72), P=0.001;37.50% (27/72), P=0.003], with statistically significant differences. There were no statistically significant differences in early abortion rate and late abortion rate between the TCM group and the control (all P>0.05). According to the stratified analysis by preparation methods, in the natural conception group, the live birth rate [60.78% (31/51)], the ongoing pregnancy rate [62.75% (32/51)], and the clinical pregnancy rate [68.63% (35/51)] in the TCM group were significantly higher than those in control group [21.43% (12/56), P<0.001; 26.79% (15/56), P<0.001; 33.93% (19/56), P<0.001]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the assisted reproductive technology group, there were no statistically significant differences in live birth rate, ongoing pregnancy rate, clinical pregnancy rate, early miscarriage rate, and late miscarriage rate between the two groups (all P>0.05). According to the stratified analysis by age, in the <35-year-old patients, the live birth rate [66.00% (33/50)], the ongoing pregnancy rate [70.00% (35/50)], and the clinical pregnancy rate [74.00% (37/50)] in the TCM group were significantly higher than those in control group [41.30% (19/46), P=0.015; 47.83% (22/46), P=0.027; 54.35% (25/46), P=0.044]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05). In the ≥35-year-old patients, the live birth rate [34.48% (10/29)], the ongoing pregnancy rate [34.48% (10/29)], and the clinical pregnancy rate [41.38% (12/29)] in the TCM group were significantly higher than those in control group [0%, P=0.001; 0%, P=0.001; 7.69% (2/26), P=0.004]; there were no statistically significant differences in early miscarriage rate and late miscarriage rate between the two groups (both P>0.05).Univariate Cox regression analysis showed that age, number of previous uterine cavity interventions, IUA score, degree of IUA, and endometrial thickness after TCRA were independent risk factors for live births, and age, IUA score, degree of IUA, intima thickness after TCRA, and treatment group were the influencing factors of persistent pregnancy (all P<0.05). After adjusting for confounding factors, multivariate Cox regression analysis showed that Wenyang Ligong Decoction significantly improved the live birth rate ( HR=3.19, 95% CI: 1.77-8.11, P=0.001) and the rate of continuous pregnancy ( HR=3.66, 95% CI: 1.80-7.48, P<0.001) in patients with IUA. Conclusion:Wenyang Ligong Decoction can significantly improve pregnancy outcomes after TCRA in patients with IUA.

Objective To investigate the effects of HIF1A-AS1 on the proliferation and apoptosis of gastric cancer cells lines BGC-823 and MKN28 and its possible mechanism.Methods The expression of HIF1A-AS1 in gastric cancer tissues was analyzed by bioinformatics.H1F1A-AS1 over expression and silenced BGC-823 and MKN28 cell strains were constructed.HIF1A-AS1 expression was detected by real-time PCR,cell proliferation was detected by CCK-8 assay,and apoptosis was detected by flow cytometry.Western blot was used to detect the expression of HIF1A protein in cytoplasm and nucleus and cellular immunofluorescence was used to detect HIF1A protein into nucleus.Results Models of BGC-823 and MKN28 gastric cancer cells with HIF1A-AS1 over-expression and silence were successfully constructed.HIF1A-AS1 over-expression decreased cell proliferation(P＜0.05),while HIF1A-AS1 over-expression significantly increased cell proliferation(P＜0.05).HIF1A-AS1 silencing significantly increased the apoptosis(P＜0.05),and HIF1A-AS1-over expression significantly decreased the apoptosis(P＜0.05).HIF1A-AS1 silencing inhibited the nucleation of HIF1A protein and over-expression promoted the nucleation of HIF1A pro-tein.HIF1A-AS1 silencing significantly decreased the expression of HIF1A cytoplasmic protein(P＜0.05)and over-expression of HIF1A-AS1 significantly increased the expression of HIF1A cytoplasm protein(P＜0.05).HIF1A-AS1 silencing significantly decreased the expression of HIF1A nuclear protein(P＜0.05)while HIF1A-AS1 over-expression significantly increased the expression of HIF1A nuclear protein(P＜0.05).Conclusions HIF1A-AS1 may promote the proliferation and inhibit apoptosis of BGC-823 and MKN28 gastric cancer cells by regulating the expression of parental gene HIF1A.
