Stroke is an acute cerebrovascular disease with high morbidity,disability and mortality.It has a rapid onset,multifarious morbidity and complex pathogenesis,with phlegm representing as an important pathogenic factor.The treatment of the acute phase of stroke is of paramount importance in determining the prognosis of patients.The method of eliminating phlegm and opening the orifices represents a pivotal approach within the domain of Chinese medicine for the treatment of the acute phase of stroke.Moreover,contemporary medical science has corroborated the efficacy of this method through the examination of its applications from a multitude of perspectives.In this paper,the theoretical basis of the method of eliminating phlegm and opening the orifices is elaborated in depth,and the mechanism and clinical application of this method in the acute phase of stroke,such as phlegm-heat and visceral solidity,phlegm-fire stasis,wind-phlegm obstruction,and phlegm-stasis inter-conjugation,are summarized in detail,with a view to providing references to the clinical treatments.

Objective To investigate the risk factors influencing postoperative recurrence of abdominal wall endometriosis(AWE).Methods A retrospective analysis was conducted on clinical data of 225 AWE patients who underwent surgery between January 2015 and December 2021.The follow-up period ranged from 30 to 108 months(mean,62.2±23.3 months).There were 16 cases of recurrence and 209 cases of non-recurrence.Univariate analysis and multivariate logistic regression were performed to identify factors associated with postoperative recurrence.Results Univariate analysis revealed that prior AWE resection history,preoperative VAS score,intraoperative lesion number,maximum diameter,and postoperative medication were significantly correlated with recurrence(P＜0.05).Multivariate logistic regression identified three independent risk factors for recurrence:prior AWE resection history(OR=4.082,95％ CI:1.019-16.354,P=0.047),multiple intraoperative lesions(OR=5.275,95％ CI:1.560-17.834,P=0.007),and absence of postoperative pharmacotherapy(OR=6.256,95％ CI:1.479-26.457,P=0.013).Conclusion Patients with a history of prior AWE excision,multiple lesions,or lack of postoperative pharmacotherapy are at higher risk of recurrence of AWE.

Objective:To explore the correlation between conventional ultrasound and contrast-enhanced ultrasound features and invasive histological features of T 1a clear cell renal cell carcinoma (ccRCC). Methods:A retrospective case series study was conducted. Sixty-seven T 1a ccRCC patients who were admitted to Shanxi Province Cancer Hospital from May 2018 to August 2023 were selected. According to the World Health Organization (WHO)/International Society of Urology and Pathology (ISUP) renal tumor grading system, the patients were divided into the low-grade group (WHO/ISUP grades 1-2, 53 cases) and the high-grade group (WHO/ISUP grades 3-4, 14 cases). The conventional ultrasound and contrast-enhanced ultrasound characteristics of two groups of patients were compared. Multivariate logistic regression model was used to analyze the independent factors of conventional ultrasound and contrast-enhanced ultrasound related to T 1a ccRCC with WHO/ISUP high grade. Results:There were no statistically significant differences in clinical characteristics between the two groups of patients (all P > 0.05). In conventional ultrasound examination, the proportion of patients with tumor exophytic rate <50% in the high-grade group was higher than that in the low-grade group [64.3% (9/14) vs. 34.0% (18/53)], and the difference was statistically significant ( χ2 = 4.23, P = 0.040); there were no statistically significant differences in the distribution of patients with different tumor maximum diameter, laterality, polarity, depth, echo, boundary, and shape between the two groups (all P > 0.05). In contrast-enhanced ultrasound examination, the proportion of patients lack of pseudocapsule sign in the high-grade group was higher than that in the low-grade group [57.1% (8/14) vs. 24.5% (13/53)], and the difference was statistically significant ( χ2 = 4.06, P = 0.044); there were no statistically significant differences in the distribution of patients with different perfusion mode, enhancement degree, enhancement uniformity, and regression mode between the two groups (all P > 0.05). Multivariate logistic regression analysis showed that the conventional ultrasound tumor exophytic rate < 50% (compared to exophytic rate ≥ 50%, OR = 3.732, 95% CI: 1.019-13.664, P = 0.047) and the absence of pseudocapsule sign (compared to the presence of pseudocapsule sign, OR = 4.357, 95% CI: 1.201-15.804, P = 0.025) on contrast-enhanced ultrasound were independent risk factors for high-grade T 1a ccRCC. Conclusions:T 1a ccRCC with the exophytic rate <50% and absence of pseudocapsule sign may have invasive histological features.

ObjectiveTo establish the quality standards for Sennae Folium（Cassia angustifolia） dispensing granules based on standard decoctions. MethodsHigh performance liquid chromatography（HPLC） specific chromatograms were established for 15 batches of Sennae Folium（C. angustifolia） standard decoctions and 10 of Sennae Folium（C. angustifolia） dispensing granules from different manufacturers， and the similarity evaluation， hierarchical cluster analysis（HCA） and principal component analysis（PCA） were performed. Linear calibration with two reference substances（LCTRS） and quantitative analysis of multi-components by single-marker（QAMS） were established for the common peaks in the specific chromatograms to determine the contents of main components in the decoction pieces， standard decoctions and dispensing granules， and to calculate their transfer rates from decoction pieces to standard decoctions and dispensing granules. ResultsThe similarities of specific chromatograms of 15 batches of Sennae Folium（C. angustifolia） standard decoctions and 10 batches of Sennae Folium（C. angustifolia） dispensing granules were all greater than 0.95， and a total of 8 characteristic peaks were calibrated， and five of them were identified， including kaempferol-3，7-O-diglucoside， apigenin-6，8-di-C-glucoside， quercetin-3-O-gentianoside， sennoside B and sennoside A. HCA and PCA results showed that there were certain differences in the composition of different batches of standard decoctions， but no clustering was observed in the production area. As the standard decoctions， the extract rate of 15 batches of samples was 26.54%-45.38%， the contents of kaempferol-3，7-O-diglucoside， apigenin-6，8-di-C-glucoside， quercetin-3-O-gentianoside， sennoside B and sennoside A were 12.16-19.26， 2.57-4.94， 3.27-5.11， 6.75-11.39， 4.69-7.79 mg·g^-1， and their transfer rates from decoction pieces to standard decoctions were 45.41%-79.02%， 29.12%-55.07%， 40.52%-67.90%， 24.72%-49.12%， 27.54%-49.34%， respectively. The extract rates of Sennae Folium（C. angustifolia） dispensing granules（C8-C10） were 38.10%-39.50%， the transfer rates of the above five components from decoction pieces to dispensing granules were 72.85%-73.58%， 53.43%-53.94%， 40.19%-40.74%， 24.62%-25.00%， 28.65%-29.11%， respectively， which were generally consistent with the transfer rates from decoction pieces to standard decoctions. ConclusionCompared with the relative retention time method， LCTRS has higher prediction accuracy and is more suitable for chromatographic columns. The established quality control standard of Sennae Folium（C. angustifolia） dispensing granules based on standard decoction is reasonable and reliable， and all indicators of samples from different manufacturers are within the range specified based on the standard decoction， which can provide reference for the quality control and process research of this dispensing granules.

ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker（QAMS） based on linear calibration using two reference substances（LCTRS）， explore the consistency between Hedyotis Herba dispensing granules and standard decoction， and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography（HPLC） specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules， and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C₁₈ columns， taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds， the retention times of the other 5 characteristic peaks were predicted and validated. Based on this， QAMS was developed to determine the contents of four components（deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid， and p-coumaric acid）. Then， the relative correction factors of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds， and each component was quantified accordingly. Finally， the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction， consistency of the specific chromatograms， contents and transfer rates of the indicator components as indexes， and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules， and four of them were identified by reference standards， namely deacetyl asperulosidic acid（peak 1）， deacetyl asperulosidic acid methyl ester（peak 3）， asperulosidic acid（peak 6） and p-coumaric acid（peak 7）. The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%， the contents of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid and p-coumaric acid were 6.62-19.70， 3.83-17.99， 1.57-6.69， 1.62-4.52 mg·g^-1， and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%， 34.03%-62.24%， 24.25%-43.70%， and 40.58%-73.71%， respectively. The extract rate， index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules（P1-P3）， produced by manufacturer A， were similar to those of the standard decoction prepared from the same batch of decoction pieces， and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules（P4-P10） from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield， consistency of specific chromatograms， contents and transfer rates of the four index components， the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction， indicating that the current production process is relatively reasonable.

ObjectiveTo establish the specific chromatogram of Chuanxiong Rhizoma dispensing granules（CRdg）， and to evaluate its quality by chemometrics and two reference substances for determination of multiple components（TRSDMC）. MethodsHigh performance liquid chromatography（HPLC） specific chromatograms were established using 13 batches of CRdg from 7 manufacturers， and preliminary quality evaluation was performed by similarity evaluation and chemometrics analysis. Eight characteristic peaks in the specific chromatogram of CRdg were measured on 22 different types of C₁₈ columns， and the actual retention times were recorded. Taking chlorogenic acid（peak 1） and senkyunolide A（peak 8） as double standard compounds， the retention times of the eight characteristic peaks were predicted by linear calibration using two reference substances（LCTRS）， and the method was validated on three other columns of different brands. Taking chlorogenic acid as reference peak， the relative correction factor method（RCFM） was used to quantify cryptochlorogenic acid， caffeic acid， ferulic acid， senkyunolide I and senkyunolide A， and the results were compared with the external standard method（ESM）. ResultsThe similarities of specific chromatograms of 13 batches of CRdg were all >0.90， and a total of 8 characteristic peaks were calibrated， and six of them were identified， including chlorogenic acid（peak 1）， cryptochlorogenic acid（peak 2）， caffeic acid（peak 3）， ferulic acid（peak 5）， senkyunolide I（peak 6） and senkyunolide A（peak 8）. Through chemometric analysis， it was found that ferulic acid， chlorogenic acid， senkyunolide I and cryptochlorogenic acid were the main components causing quality difference in CRdg， and the accuracy of LCTRS in predicting the retention time of 8 characteristic peaks was superior to that of the relative retention time method（RRT）. Further comparison of the results obtained from RCFM and ESM showed that there was no statistically significant difference between the two methods. ConclusionA quality evaluation method for CRdg based on HPLC specific chromatogram and TRSDMC is established， its qualitative accuracy is better than that of RRT， the quantitative accuracy is similar to that of ESM， and 4 quality-differentiated components among different manufacturers are found. This method is stable and reliable， and has reference value for the quality evaluation of other dispensing granules.

Objective To analyze the value of serum neutrophil count (NEUT), homocysteine (Hcy), adiponectin (APN) and blood glucose in predicting the occurrence of acute myocardial infarction (AMI) in patients with coronary heart disease. Methods The clinical data of 98 patients with coronary heart disease who were admitted to the hospital from March 2022 to March 2024 were collected retrospectively. Patients included were divided into AMI group (n=33) and non-AMI group (n=65) according to the presence and absence of AMI. Baseline data, complications, ultrasound examination data and laboratory examination data were collected. Multivariate logistic regression analysis was performed to identify the influencing factors of AMI in patients with coronary heart disease. The receiver operating characteristic curves were used to evaluate the predictive value of NEUT, Hcy, APN and blood glucose for AMI in patients with coronary heart disease. Results The levels of fasting plasma glucose (FPG), 2-hour postprandial plasma glucose (2hPG), glycosylated hemoglobin (HbA1c), NEUT, APN, Hcy, N-terminal pro B-type natriuretic peptide (NT-proBNP), C-reactive protein (CRP), red blood cell distribution width (RDW) and white blood cell (WBC) in the AMI group were higher than those in the non-AMI group (P<0.05). Logistic regression analysis found that FPG, 2hPG, HbA1c, NEUT, APN, Hcy, NT-proBNP, CRP, RDW, and WBC were independent influencing factors of AMI in patients with coronary heart disease (P<0.05). ROC curves indicated that the levels of FPG, 2hPG, HbA1c, NEUT, APN and Hcy were abnormally elevated in patients with coronary heart disease. Above indicators were helpful for predicting the occurrence of AMI. The area under the curve (AUC) and sensitivity of FPG for predicting AMI in patients with coronary heart disease were the best (P<0.05). Conclusion Abnormal elevated levels of FPG, 2hPG, HbA1c, NEUT, APN and Hcy are independent risk factors for AMI in patients with coronary heart disease. All of these indicators have predictive value.

Objective To construct a patient decision aid(PtDA)for exercise training in pa-tients with chronic obstructive pulmonary disease(COPD)and explore its impacts on decision-making quality of patients' exercise regimens.Methods The development of the PtDA for exercise training in COPD patients was accomplished through literature analysis,the Delphi method,and user surveys,followed by an intervention study.A total of 59 inpatients with COPD were included as study sub-jects.The control group received routine care along with general exercise training guidance,while the intervention group received routine care combined with shared decision-making for exercise training based on the PtDA.The decision conflict and decision preparedness levels of patients in both groups were compared before the intervention and on the day of discharge.The exercise self-efficacy of pa-tients was measured before intervention,on the day of discharge,and 1 month and 3 months after dis-charge.Results The intervention group had significantly lower scores for decision conflict and signif-icantly higher scores for decision preparedness and exercise self-efficacy compared with the control group(P＜0.05).Conclusion The PtDA for exercise training can improve decision conflict and de-cision preparedness in COPD patients,enhance their exercise self-efficacy levels,and provide references for healthcare professionals in improving exercise adherence.

Objective To explore the changes in the levels of serum myocardial injury markers troponin I(cTNI),myoglobin(MYO),creatine kinase isoenzyme(CK-MB),and N-terminal pro-B natriuretic peptide precursor(NT-proBNP)in elderly patients with hypertension complicated with heart failure and their clinical value.Methods A total of 110 elderly patients with hypertension complicated with heart failure in the hospi-tal from February 2022 to February 2024 were selected as the hypertension complicated with heart failure group.During the same period,110 patients with simple heart failure were selected as the heart failure group,and 110 patients with simple hypertension were selected as the hypertension group.The levels of serum cTNI,MYO,CK-MB and NT-proBNP in each group were compared.Multivariate Logistic regression was used to an-alyze the influencing factors of hypertension complicated with heart failure.The receiver operating characteris-tic(ROC)curve was drawn to analyze the diagnostic efficacy of serum cTNI,MYO,CK-MB and NT-proBNP for hypertension complicated with heart failure.Results Compared with the hypertension group,the levels of serum cTNI,MYO,CK-MB and NT-proBNP in the hypertension combined with heart failure group and the heart failure group increased(P＜0.05);Compared with the heart failure group,the levels of serum MYO and NT-proBNP in the hypertension combined with heart failure group increased(P＜0.05).The results of multi-variate Logistic regression analysis showed that NT-proBNP was an independent influencing factor for hyper-tension complicated with heart failure(P＜0.05).The results of the ROC curve showed that the areas under the curve of serum cTNI,MYO,CK-MB,and NT-proBNP alone and in combination for the diagnosis of hyper-tension complicated with heart failure were 0.768,0.729,0.687,0.904,and 0.905,respectively.The sensitivi-ties were 96.4％,50.0％,79.1％,90.0％and 90.9％respectively,and the specificities were 54.1％,100.0％,60.0％,78.2％and 75.0％respectively.Conclusion Serum cTNI,MYO,CK-MB and NT-proBNP are highly expressed in elderly patients with hypertension complicated with heart failure.The combination of the four has a high diagnostic value for hypertension complicated with heart failure.
