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.

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 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.

Evaluating and identifying the occurrence risk of hepatocellular carcinoma (HCC) can make the gateway for prevention and diagnosis advance as well as assist in the early detection and intervention of future HCC occurrences within the population. Early-stage diagnosis and treatment are crucial for improving survival rates in patients with HCC. This article reviews the recent years' research progress in terms of combining three aspects-molecular markers, scoring models, and early-stage diagnostics-to predict the evaluation of HCC occurrence risk, with the hope of providing guiding significance for clinical practice.

ObjectiveTo investigate the effect of the multidisciplinary team （MDT） management model in improving the prognosis of patients with cirrhotic portal hypertension. MethodsA total of 86 patients with cirrhotic portal hypertension who were admitted to Shenzhen Third People’s Hospital from May 2022 to July 2024 were enrolled， and according to whether the MDT treatment regimen was implemented， they were divided into execution group with 51 patients and non-execution group with 35 patients. Baseline clinical data were collected， and the patients were observed in terms of gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death from admission to the end of follow-up （January 2025）. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. The Kaplan-Meier method was used to plot survival curves for the cumulative incidence rates of endpoint events （gastrointestinal bleeding， hepatic encephalopathy， liver cancer， and death）， and the Log-rank test was used for comparison between groups. The Cox proportional-hazards regression model analysis was used to investigate the effect of MDT management on the prognosis of patients. ResultsThere were significant differences between the execution group and the non-execution group in diameter of the portal vein （t=1.216， P=0.017） and ascites （χ²=4.515， P=0.034） at baseline. The patients were followed up for 14.6±6.2 months， and the survival curve analysis showed that there was a significant difference in the cumulative incidence rate of gastrointestinal bleeding between the two groups （χ²=4.573， P=0.024）， while there were no significant differences in the incidence rates of other outcome events between the two groups （all P>0.05）. The Cox regression analysis showed that the execution group had a reduced risk of gastrointestinal bleeding （hazard ratio=0.262， 95% confidence interval： 0.110 — 0.630， P=0.003）. ConclusionImplementation of the MDT treatment regimen can significantly reduce the short-term risk of gastrointestinal bleeding in patients with cirrhotic portal hypertension， while its long-term benefits require further follow-up verification.

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.

Hereditary angioedema(HAE)is a rare autosomal dominant disorder characterized by recur-rent,unpredictable episodes of skin and mucosal edema,which may affect the face,extremities,respiratory tract,gastrointestinal tract,and genitals,with a global prevalence of approximately 1 in 50 000.This case re-port presents a young female patient with a history of recurrent abdominal pain and multisite edema.During an acute episode,laboratory tests revealed decreased complement C4 levels along with reduced concentration and function of C1 esterase inhibitor.Computed tomography(CT)demonstrated bowel wall edema and pelvic effu-sion.Previously undiagnosed,the patient was admitted for this acute attack and was ultimately diagnosed with HAE following a multidisciplinary treatment(MDT)team discussion at our hospital.The rapid diagnosis and treatment of this case highlight the critical role of MDT in the management of complex and rare diseases.

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 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.
