Diabetic kidney disease （DKD）， a common complication of diabetes mellitus， is a leading global cause of end-stage renal disease （ESRD）. Current therapeutic strategies primarily focus on symptomatic management but exhibit limited efficacy in halting disease progression to ESRD， and some drugs carry non-negligible toxic side effects. Traditional Chinese medicine （TCM） has a long history in treating DKD， with single TCM and TCM compounds demonstrating unique advantages in multi-target， multi-pathway， and multi-effect therapeutic interventions. Tripterygium wilfordii （TW）， known for its effects in promoting blood circulation， dredging collaterals， dispelling wind， removing dampness， reducing swelling， and alleviating pain， contains bioactive components such as Tripterygium glycosides （TWG）， triptolide （TPL）， tripdiolide （TPD）， and celastrol （CEL）. The active ingredients possess various functions， including regulating immune-inflammatory balance， ameliorating renal fibrosis and glomerulosclerosis， combating oxidative stress， protecting podocytes， and improving glucose and lipid metabolism， all of which play a significant role in the treatment of DKD. This review summarized the mechanisms underlying the therapeutic effects of T. wilfordii and its active ingredients on DKD， aiming to provide insights for clinical management and novel drug development of DKD.

Objective To analyze the epidemiologic burden of colorectal cancer in Xishan District, Kunming City, Yunnan Province from 2018 to 2020. Methods Indicators of epidemiologic burden were calculated, including incidence rate, mortality rate, age-specific incidence/mortality rates, potential years of life lost (PYLL), and disability-adjusted life years (DALY) based on the National Disease Control and Prevention Center’s "Cancer Information Registration and Reporting System" and "Cause of Death Registration System". Results From 2018 to 2020, the ASR (China) for the incidence of colorectal cancer in Xishan District, Kunming City increased from 25.27/10⁵ to 26.29/10⁵, while the ASR (China) for mortality decreased from 17.11/10⁵ to 16.03/10⁵. The PYLL in 2018–2020 were 1399.63, 1376.78, and 1571.56 person-years, respectively, whereas the DALY in 2018–2020 were 1927.74, 1875.05, and 1945.17 person-years, respectively. The morbidity, mortality, PYLL, and DALY were generally higher in males than in females over 45 years of age. Conclusion Given the parallel trends of persistent incidence risk and steadily declining mortality for colorectal cancer in Xishan District, Kunming City, a three-tier prevention and control system centered on "lifestyle intervention–regular screening–positive case tracking" should be established, with a focus on covering high-risk populations, particularly males over 45 years of age.

Parkinson's disease （PD） is a common neurodegenerative disorder characterized by motor impairments， with its pathological mechanisms involving multiple processes such as the degeneration of dopaminergic neurons and the abnormal aggregation of α-synuclein. Current Western medical treatments face challenges including diminished long-term efficacy and motor complications. In recent years， Traditional Chinese Medicine （TCM） has demonstrated advantages in the prevention and treatment of PD through its systematic regulatory capabilities， featuring multi-component， multi-target， and multi-pathway approaches.This article systematically reviews the roles of seven key signaling pathways-NF-κB， AMPK/mTOR， PI3K/Akt， MAPKs， Nrf2/ARE， Wnt/β-catenin， and BDNF/TrkB-in the pathological process of PD and the regulatory mechanisms of TCM. Research indicates that active ingredients of Chinese herbs and compound formulations can synergistically modulate these pathways， exerting comprehensive effects in inhibiting neuroinflammation， alleviating oxidative stress， promoting autophagy to clear abnormal proteins， and enhancing neurotrophic support. These signaling pathways form a complex regulatory network through crosstalk among key nodal molecules， constituting an intricate regulatory system in PD pathology. The multi-target intervention characteristics of TCM align well with this network-based regulatory requirement， achieving integrated anti-inflammatory， antioxidant， autophagy-regulating， and neurorestorative effects through synergistic multi-pathway modulation. This article systematically outlines the mechanisms of TCM in the coordinated regulation of multiple pathways， providing a theoretical basis for elucidating the pathological process of PD and the intervention mechanisms of TCM， while also offering new perspectives and directions for modern research on TCM in the prevention and treatment of PD.

Objective To analyze survival outcomes and influencing factors among patients with colorectal cancer in Yunnan Province. Methods Clinical data were retrospectively collected from 4 892 patients with colorectal cancer. Survival data were obtained through follow-up. Overall survival (OS) was calculated by using the Kaplan-Meier method. Univariate analysis was performed by applying the log-rank test. Meanwhile, multivariate analysis employed the Cox proportional hazards regression model. Results The 1-, 3-, 5-, and 10-year OS rates for the entire cohort were 91.90%, 74.40%, 64.40%, and 28.70%, respectively. Univariate analysis revealed that age, ethnicity, region, differentiation grade, TNM stage, clinical stage, metastatic status, histological type, and treatment modality (chemotherapy, radiotherapy, and surgery) were associated with patient prognosis (all P<0.05). Multivariate analysis identified age (HR=1.250), region (HR=1.262), differentiation grade (HR=0.761), clinical stage (HR=3.128), and treatment modality (chemotherapy, HR=0.644; radiotherapy, HR=1.605; surgery, HR=0.384) as independent factors affecting survival prognosis in patients with colorectal cancer (all P<0.001). Conclusion Age, region, clinical stage, and treatment modality are independent factors influencing survival among patients with colorectal cancer in Yunnan Province. In clinical practice, these factors should be integrated to develop individualized prevention and treatment strategies, thereby improving patient outcomes.

Objectives:To explore the predictive value of residual Murray's law-based quantitative flow ratio(μQFR)on long-term vessel-oriented composite endpoints(VoCE).Methods:This retrospective study included 3 510 patients from the FAVOR Ⅲ China trial.Offline residual μQFR analysis was performed on all vessels(diameter≥2.5 mm)with 50%-90%stenotic lesions.Patients were stratified into high-,intermediate-,and low-risk groups based on residual μQFR tertiles.The primary endpoint was 3-year VoCE,defined as a composite of cardiac death related to the target vessel,target vessel-related spontaneous myocardial infarction,and ischemia-driven target vessel revascularization.Results:Offline analysis was performed on 5 256 vessels from 3 510 patients.The mean residual μQFR was 0.92±0.75.The high-risk group(residual μQFR≤0.91)with 1 554 patients(1 958 vessels);the intermediate-risk group(residual μQFR 0.92-0.96)with 1 211 patients(1 906 vessels);and the low-risk group(residual μQFR>0.96)with 745 patients(1 392 vessels).Over 3-year follow-up,VoCE occurred in 227 vessels(4.3%).The 3-year VoCE incidence was significantly higher in the high-risk group compared to the intermediate-and low-risk groups(6.2%vs.4.1%vs.2.5%,log-rank P<0.001),primarily driven by ischemia-driven target vessel revascularization(5.0%vs.3.0%vs.1.6%,log-rank P<0.001).Hypertension(OR=0.83,95%CI:0.72-0.96),hypercholesterolemia(OR=0.84,95%CI:0.73-0.97),bifurcation lesions(OR=0.72,95%CI:0.63-0.83),moderate/severe calcification(OR=0.70,95%CI:0.57-0.84),and tandem lesions(OR=0.59,95%CI:0.47-0.75)were independent predictors of lower residual μQFR values.Conclusions:Lower residual μQFR is significantly associated with increased VoCE risk during the 3-year follow up period.

Objective To evaluate the safety and efficacy of the Neuroform EZ self expanding stent for severe symptomatic intracranial atherosclerotic stenosis(sICAS).Methods Retrospectively enrolled consecutive patients with severe sICAS who underwent percutaneous transluminal angioplasty and stenting(PTAS)with a Neuroform EZ stent in the Department of Cerebrovascular Disease,Henan Provincial People's Hospital,from March 2020 to December 2022.Baseline demographic and clinical data were collected,including age,sex,hypertension,diabetes mellitus,coronary artery disease,dyslipidemia,hyperhomocysteinemia,transient ischemic attack(TIA)and ischemic stroke,smoking history,modified Rankin scale(mRS)score at admission,and National Institutes of Health stroke scale(NIHSS)score.Preoperative imaging data included target vessel(basilar artery,intracranial segment of the internal carotid artery,middle cerebral artery,and intracranial vertebral artery),lesion length,degree of stenosis,and vascular morphology according to the Mori classification(type A,lesion length＜5 mm with concentric or moderately eccentric stenosis;type B,lesion length＜10 mm with severely eccentric stenosis;type C,lesion length＞10 mm or arterial angulation＞90°).Technical success was defined as accurate delivery and deployment of the stent with complete coverage of the target lesion and immediate post deployment residual stenosis＜50%.Postoperative head CT was performed to detect intracranial hemorrhage.Periprocedural complications were recorded,including intracranial hemorrhage,arterial dissection,in stent thrombosis,and perforator occlusion occurring intraoperatively within 72 hours after the procedure.At one-month post-operation,patients were seen through outpatient follow-up for TIA,hemorrhagic or ischemic stroke,and all cause death.At 6 months after surgery,DSA or CT angiography(CTA)was performed to assess in stent restenosis(ISR,defined as＞50%stenosis within the stent or within5mm of its edges,or＞20%luminal loss).At 1 and 2 years postoperatively,ipsilateral ischemic stroke or TIA recurrence was assessed by outpatient visit or telephone follow up.Results A total of 76 patients with severe sICAS underwent PTAS with a Neuroform EZ stent(56 males,20 females,age 47-80 years,with a mean age of[61±10]years).(1)Within all patients enrolled,40 had middle cerebral artery,16 with basilar artery,6 with intracranial vertebral artery and 14 with intracranial internal carotid artery.The preprocedural lesion length was 2-15 mm,with a mean length of(6.2±2.5)mm,and stenosis severity was70%-99%,the mean severity was(83.2±6.9)%,with Mori type B being the most common type(57.9%[44/76]).(2)PTAS was successfully completed on all patients(technical success 100%).Pre dilation with a conventional balloon was performed in all cases(using balloon with diameter of 1.5-3.5mm,and stent with diameter of 2.5-4.5 mm and length of 15-30 mm).Immediate post procedural residual stenosis was(17.4±9.0)%,significantly lower than baseline(t=52.9,P＜0.05),with a mean difference of 65.8%(95%CI63.3%-68.3%).(3)Among all 76patients,one patient developed a flow limiting dissection post balloon angioplasty,which recovered after stent deployment.One patient with basilar artery stenosis experienced recurrent ischemic stroke at 5-day postoperatively,presenting with right sided weakness and coughing on liquids.Imaging showed an acute infarct in the left pons,considered perforator occlusion.The overall periprocedural complication rate was 2.6%(2/76).(4)No deaths occurred within 30 days after surgery.Sixty nine patients(90.8%)underwent 6 month imaging follow up with DSA(52 cases)or CTA(17 cases).ISR occurred in 12 patients(17.4%),including 6 asymptomatic and 6symptomatic cases.The ipsilateral ischemic stroke recurrence rate was 6.6%(5/76)at1 year and13.2%(10/76)at2years.Conclusions Neuroform EZstent assisted PTASappears safe and feasible for the treatment of severe sICAS.The long term effectiveness requires confirmation in large,multicenter,prospective studies.

Objective To investigate the characteristics of macrophage depletion by clodronate liposomes(CL)in a carbon tetrachloride(CCl4)-induced liver fibrosis mouse model,and to analyze the transcriptomic features.Methods Thirty-two C57BL/6 mice were divided randomly into plain control liposomes for clophosome(PL)and clodronate liposome(CL)groups(n=16 mice per group),and administered intraperitoneal injections of PL and CL,respectively.On day 5,each group was further divided into normal(N)and model(M)subgroups(n=8 mice per subgroup).Mice in group M received 10％CCl4 intraperitoneally to induce liver fibrosis,while mice in group N received an equal volume of olive oil.After 4 weeks,serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels were measured,and hepatic inflammation and collagen deposition were evaluated by hematoxylin/eosin and Sirius red staining,respectively.Total RNA was extracted from liver tissues for transcriptomic sequencing and subsequent differential gene expression analysis.Results Serum ALT and AST levels were significantly elevated in the PL-M group(P＜0.01),with fibrosis staging primarily at S3,compared with S1 in the CL-M group.Totals of 1462 and 2119 differentially expressed genes(|log fold change|＞2 and P＜0.05)were identified in the PL and CL groups,respectively.Gene Ontology analysis revealed enrichment in multiple biological processes,cellular components,and molecular functions in both models,and Kyoto Encyclopedia of Genes and Genomes analysis identified 29 significantly enriched pathways(P＜0.05).The upregulation of genes including Lgals7 and Timp1 and the downregulation of Mup-ps16 and Mup15 were validated by reverse transcription-quantitative polymerase chain reaction,consistent with transcriptomic trends(P＜0.05).Conclusions This study highlights the characteristics and transcriptomic features of macrophage depletion in the CCl4-induced liver fibrosis model,providing a theoretical reference for research on the immune mechanisms of liver fibrosis.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

Objective:To observe the changes in serum estradiol (E 2) levels in pregnant women of different gestational weeks and their predictive value for early intrauterine pregnancy outcomes. Methods:A retrospective study was conducted involving 375 pregnant women who were treated at the Affiliated Yangming Hospital of Ningbo University (Yuyao People's Hospital) from September 2021 to September 2023. The clinical data were categorized based on pregnancy outcomes into three groups: a normal pregnancy group ( n = 150), a threatened miscarriage with continued pregnancy group ( n = 150), and a miscarriage group ( n = 75). The serum estradiol (E 2) levels at different gestational weeks were compared among the three groups: 5 to < 6 weeks (35-41 days), 6 to < 7 weeks (42-48 days), and 7 to 8 weeks (49-55 days). The predictive value of serum E 2 levels for early intrauterine pregnancy outcomes across different gestational weeks was analyzed using Receiver Operating Characteristic (ROC) curves. Results:In the normal pregnancy group, the serum E 2 levels at different gestational weeks were as follows: (1 691.87 ± 532.21) pmol/L for 5 to < 6 weeks, (2 376.64 ± 788.36) pmol/L for 6 to < 7 weeks, and (3 576.30 ± 1,190.06) pmol/L for 7 to 8 weeks. These values were significantly higher than those in the threatened miscarriage with continued pregnancy group [(1 409.28 ± 473.49) pmol/L, (1 893.13 ± 563.15) pmol/L, (2 035.79 ± 612.47) pmol/L, t = 5.15, 11.68, 6.60, all P < 0.05] and the miscarriage group [(906.49 ± 338.09) pmol/L, (923.63 ± 365.39) pmol/L, (950.27 ± 378.89) pmol/L, t = 16.19, 15.45, 21.50, all P < 0.05]. The serum E 2 levels at different gestational weeks in the threatened miscarriage with continued pregnancy group were significantly higher than those in the miscarriage group ( t = 7.48, 10.81, 8.89, all P < 0.05). Both the normal pregnancy group and the threatened miscarriage with continued pregnancy group showed an increasing trend in serum E 2 levels with advancing gestational weeks ( t = 6.74, 18.55, 7.58, 9.82, 11.81, 2.24, all P < 0.05). In contrast, the serum E 2 levels in the miscarriage group also increased with advancing gestational weeks, but the differences were not statistically significant ( P > 0.05). The results from the receiver operating characteristic curve analysis indicated that the areas under the curve for predicting early intrauterine pregnancy outcomes based on serum E 2 levels at different gestational weeks were 0.857, 0.810, and 0.839, demonstrating excellent diagnostic efficacy. Conclusions:Dynamic monitoring of serum E 2 levels is beneficial for predicting early intrauterine pregnancy outcomes and providing guidance for clinical diagnosis and treatment.
