Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective:To compare the preoperative presentation, intraoperative findings, and postoperative outcomes between middle ear cholesteatoma with tympanosclerosis （MECwTS） and middle ear cholesteatoma without tympanosclerosis （MECw/oTS）, thereby investigating the clinical characteristics of MECwTS. Methods:A retrospective analysis was conducted on the clinical data of 120 patients with middle ear cholesteatoma. Patients were divided into two groups based on the presence or absence of concomitant tympanosclerosis: the MECwTS group （n=49） and the MECw/oTS group （n=71）. All patients underwent preoperative evaluations including temporal bone CT, otoscopic examination, pure-tone audiometry, tympanometry, and assessment using the Zurich Chronic Middle Ear Inventory （ZCMEI-21） quality of life scale. All patients underwent canal wall down mastoidectomy with tympanoplasty. Concurrent ossicular chain reconstruction was performed: partial ossicular replacement prosthesis （PORP） in 83 cases and total ossicular replacement prosthesis （TORP） in 37 cases. Intraoperative disease severity was assessed using the Cholesteatoma Comprehensive Score Scale （CCSS）. Postoperative follow-up lasted at least one year and included pure-tone audiometry, otoscopic examination, and the ZCMEI-21 scale administered at ≥1 year post-surgery. Preoperative and postoperative air-bone gap （ABG） and ZCMEI-21 scores were compared between the MECwTS and MECw/oTS groups. Additionally, surgical efficacy was defined as a postoperative ABG ≤20 dB; the hearing improvement efficacy of PORP versus TORP was compared based on this criterion. Results: ①Preoperative ABG showed no significant difference between the MECw/oTS and MECwTS groups（P>0.05）. Postoperative ABG was （18.65±10.21） dB in the MECw/oTS group versus （22.55±9.53） dB in the MECwTS group, demonstrating a statistically significant intergroup difference （P<0.05）. ②Intraoperative CCSS scores were significantly higher in the MECwTS group （8.04±2.18） compared to the MECw/oTS group （5.93±1.44） （P<0.05）. ③Preoperative ZCMEI-21 scores showed no significant difference between groups （P>0.05）. Postoperative ZCMEI-21 scores were （22.24±8.11） in the MECw/oTS group versus （27.02±7.21） in the MECwTS group, indicating a statistically significant difference （P<0.05）. ④Postoperative ABG ≤20 dB was achieved in 54 patients （65.06%, 54/83） in the PORP group and 16 patients （43.24%, 16/37） in the TORP group. This difference in efficacy rates was statistically significant （P<0.05）. The overall efficacy rate for ossiculoplasty was 58.33% （70/120）. Conclusion: Patients with MECwTS exhibit more severe middle ear and mastoid pathology compared to those with MECw/oTS, resulting in poorer postoperative hearing levels and quality of life outcomes. Both PORP and TORP implantation can improve postoperative hearing to some extent; however, PORP appears to offer superior hearing improvement efficacy compared to TORP.

Objective To investigate the value of the nomogram model based on the apparent diffusion coefficient(ADC)value of the cervical spinal cord in predicting neurological recovery after cervical spondylotic myelopathy(CSM).Methods One hundred CSM patients undergoing decompression surgery were prospectively enrolled.All patients underwent conventional cervical spine MRI and sagittal position non-shared incentive diffusion weighted imaging(ZOOM-DWI)examination before surgery.The improvement rate of neurological function was calculated according to the modified Japanese Orthopaedic Association(mJOA)score before and 6 months after surgery and divided into the good improvement group(60 patients)and the poor improvement group(40 patients)according to the improvement rate.Independent risk factors for postoperative outcomes were determined by univariate and multivariate logistic regression.Then the prediction model based on the clinical-imaging feature(model 1)and clinical-imaging feature-ADC value(model 2)were established,the receiver operating characteristic(ROC)curve was drawn,and the DeLong test was performed to compare the discrimination efficiency of the two models.A nomogram,calibration curve,and clinical decision curve were drawn for model 2.Results Age,body mass index(BMI),diabetes mellitus,T2 hyperintense,cross-sectional area,and ADC values at the disc level of different segments were independent risk factors affecting the outcome of CSM.The area under the curve(AUC)of the ROC curve constructed by model 2(AUC=0.933)was higher than that of model 1(AUC=0.864).The DeLong test showed that the difference between the two models was statistically significant(P＜0.05).The nomogram,calibration curve,and decision curve analysis(DCA)of model 2 showed that it had good differentiation,accuracy,and clinical value.Conclusion The nomogram model based on ADC value can effectively predict the outcome of postoperative neurological recovery in CSM patients.

Objective To investigate the relationship between quantitative parameters of the histogram of global fat fraction(FF)in the infrapatellar fat pad(IPFP)and the severity of knee osteoarthritis(KOA).Methods A total of 120 patients were prospectively selected and divided into the non-KOA group(KL grade 0-1),the mild KOA group(KL grade 2),and the severe KOA group(KL grade 3-4)based on the Kellgren-Lawrence(KL)classification criteria of knee X-rays.The FF maps of the IPFP were obtained based on the mDIXON-Quant technique.The region of interest(ROI)was delineated using 3D Slicer software,and global histogram analysis was performed to obtain quantitative parameters,including mean,median,10th percentile(10th),90th percentile(90th),skewness,kurtosis,and entropy.Pearson or Spearman correlation analysis was used to evaluate the correlation between each quanti-tative parameter and the severity of KOA.The diagnostic efficacy was analyzed using the receiver operating characteristic(ROC)curves.Results As the progression of KL classification,the mean,median,percentiles,and kurtosis of the global FF histogram quantitative parameters in the IPFP decreased,while skewness and entropy increased,with statistically significant among the three groups(P＜0.001).The mean,median,10th,90th,and kurtosis showed negative correlations with the KL classification(r=-0.563,-0.448,-0.614,-0.294,-0.450),while skewness and entropy showed positive correlations with the KL classification(r=0.385,0.637),all of which were statistically significant(P＜0.05).The area under the curve(AUC)for diagnosing KOA were 0.799,0.725,0.828,0.636,0.741,0.688,and 0.830,respectively.The sensitivity of the 10th and entropy were 74.4％and 77.9％,respectively,and the specificity were 85.3％and 88.2％,respectively.Conclusion The quantitative parameters of the histogram of global FF in the IPFP are correlated with the severity of KOA and can reflect the pathophysiological changes in the IPFP.They can serve as objective indicators for diagnosing KOA and assessing its severity.

Objective To observe the value of fetal MRI in diagnosis of duodenal obstruction(DO).Methods A total of 35 fetuses with suspected DO according to MRI were retrospectively included.The length and the maximum diameter of the dilated duodenum were measured,so as site(categorized in descending order from proximal to distal as descending segment,horizontal segment and ascending duodenum/proximal jejunum)and the degree of obstruction(complete or incomplete)were assessed.Taken findings of labor induction specimen,postnatal neonatal surgery or follow-up data as standards,the positive predictive value(PPV)of MRI for diagnosing fetal DO was calculated,while the correlations of the measured parameters of dilated duodenum and the confirmed obstruction site/degree were analyzed.Results Among 35 fetuses,DO was confirmed in 34 fetuses,yielding an overall PPV of 97.14％(34/35)for MRI.In 34 fetuses with confirmed DO,there were 23 with descending DO(DDO),4 with horizontal DO(HDO)and 7 with ascending DO/proximal jejunum obstruction(ADO/PJO),including 12 with complete DO and 22 with incomplete DO.PPV of MRI for diagnosing DDO,HDO and ADO/PJO was 87.50％(21/24),50.00％(2/4)and 100％(7/7),respectively,for diagnosing complete and incomplete DO was 90.00％(9/10)and 84.00％(21/25),respectively.Both the length and the maximum diameter of fetal proximal dilated duodenum showed on MRI were positively correlated with the actual obstruction site(from proximal to distal)(rs=0.736,P＜0.001;rs=0.424,P=0.011,respectively),but had no significant rank correlation with the degree of obstruction(rs=-0.216,P=0.212;rs=-0.285,P=0.097,respectively).Conclusion Fetal MRI could effectively evaluate the length and the maximum diameter of dilated duodenum hence indicating the level and degree of DO.

Objective To investigate the changes in metabolites detected by magnetic resonance spectroscopy(MRS)in the dorsal thalamus of patients with cervical spondylotic myelopathy(CSM)and to analyze their correlation with spinal cord injury based on diffusion tensor imaging(DTI).Methods A total of 93 patients with CSM(patient group)and 67 healthy volunteers(control group)were selected.DTI parameters of the spinal cord and MRS parameters of the thalamus were compared between the two groups.Correlation analysis were performed among clinical features,conventional imaging features,DTI parameters,and metabolites in CSM patients.Multifacto-rial linear regression equations for thalamic metabolites based on the aforementioned characteristics were established.Results The fractional anisotropy(FA)value was significantly lower in the patient group than in the control group(P=0.005,t=2.874).The N-acetyl aspartate/creatine(NAA/Cr)ratio(P<0.001,Z=-5.922),choline/Cr(Cho/Cr)ratio(P<0.001,Z=-6.857),and myo-inositol/Cr(MI/Cr)ratio(P<0.001,Z=-6.573)were significantly lower in the patient group than in the control group.The NAA/Cr ratio(r=0.444,P<0.001),Cho/Cr ratio(r=0.308,P=0.003),and MI/Cr ratio(r=-0.489,P<0.001)were corre-lated with the FA value in the patient group.There was a correlation between the NAA/Cr ratio and the duration(r=-0.365,P<0.001).Multifactorial linear regression equations for each metabolites in the thalamus:NAA/Cr=0.833+1.520×FA-0.007×duration;Cho/Cr=0.209+0.774×FA;MI/Cr=1.566-1.722×FA+0.008×modified Japanese Orthopaedic Association(mJOA)score;glu-tamate/Cr(Glx/Cr)=0.942+0.009×duration.Conclusion CSM patients exhibit metabolic alterations in the dorsal thalamus,which are linearly correlated with the degree of spinal cord injury.

Objective: To investigate trends of incidence, mortality, and years of life lost (YLL) rate of lung cancer in cancer registration areas of Guizhou Province from 2017 to 2021, so as to provide references for formulating lung cancer prevention and control strategies and reducing the disease burden of lung cancer. Methods: The qualified lung cancer registration data from cancer registration areas of Guizhou Province from 2017 to 2021 were collected, the crude incidence and mortality of lung cancer were calculated by urban/rural areas, genders and ages. The standardized incidence and standardized mortality was calculated using the age structure of the standard population from the Fifth National Population Census in 2000. YLL was calculated using the standard life table from the Global Burden of Disease Study 2019. The disease burden of lung cancer was assessed using incidence, mortality, and YLL rate, and the trend in the disease burden of lung cancer from 2017 to 2021 was calculated using annual percent change (APC). Results : From 2017 to 2021, the crude incidence, standardized incidence, crude mortality, standardized mortality, YLL and YLL rate in Guizhou Province were 53.13/100 000, 37.58/100 000, 42.77/100 000, 29.44/100 000, 98.19 thousand person-years and 10.95‰, respectively. The standardized incidence and standardized mortality of lung cancer were higher in rural areas than in urban areas (39.45/100 000 vs. 34.23/100 000, 30.68/100 000 vs. 27.18/100 000). The standardized incidence and standardized mortality of lung cancer were higher in males than in females (49.34/100 000 vs. 26.47/100 000, 41.31/100 000 vs. 18.28/100 000). The crude incidence and crude mortality of lung cancer increased with age, peaking in the 80-<85 age group (360.84/100 000) and the ≥85 age group (414.85/100 000), respectively. From 2017 to 2021, the standardized incidence demonstrated downward trends in the total population, urban areas and males (APC=-6.590%, -5.829%, and -6.729%, all P<0.05). The standardized mortality demonstrated downward trends in urban areas and females (APC=-3.710% and -5.378%, both P<0.05). The YLL rate also showed downward trends in urban areas and females (APC=-3.957% and -3.631%, both P<0.05). Conclusions From 2017 to 2021, the overall disease burden of lung cancer in registration areas of Guizhou Province showed a decreasing trend. However, the disease burden remained relatively heavier in rural areas and males, with a relatively gradual change.

A traditional Chinese medicine(TCM)monomer is a bioactive compound extracted from Chinese herbal medicines possessing determined biological activity and pharmacological effects,and has gained much attention for treating neuronal diseases.However,the application of TCM monomers is limited by their low solubility and poor ability to cross the blood-brain barrier(BBB).Exosomes are small extracellular vesicles(EVs)ranging in size from 30 to 150 nm in diameter and can be used as drug delivery carriers that directly target cells or tissues with unique advantages,including low toxicity,low immunogenicity,high stability in blood,and the ability to cross the BBB.This review discusses the biogenesis,components,stability,surface modification,isolation technology,advantages,and disadvantages of exosomes as drug carriers and compares exosomes and other similar drug delivery systems.Furthermore,exosome-encapsulated TCM monomers exert neuroprotective roles,such as anti-inflammation,anti-apoptosis,anti-mitophagy,and anti-oxidation,in various neuronal diseases,including Alzheimer's disease(AD),Parkinson's disease(PD),multiple sclerosis(MS),and cerebral ischemia and reperfusion(CI/R)injury,as well as anti-drug resistance,anti-tumorigenesis,anti-angiogenesis,and promotion of apoptosis in brain tumors,providing more inspiration to promote the development of an exosome-based delivery tool in targeted therapy for neuronal diseases.
