Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

ObjectiveTo analyze the epidemiological characteristics of 8 major respiratory pathogens in influenza-like illness (ILI) cases with acute respiratory infections at fever clinics in Huangpu District, Shanghai from 2015 to 2024, and to provide a scientific basis for the prevention and treatment of respiratory diseases. MethodsA retrospective study was conducted in Huangpu District. Individuals meeting the case definition of ILI from 2015 to 2024 was registered. Their nasopharyngeal swabs were collected for pathogen detection. A total of 8 respiratory viruses were tested, including Influenza A virus (Flu A), Influenza B virus (Flu B), adenovirus (ADV), enterovirus/human rhinovirus (EV/HRV), human parainfluenza virus (HPIV), human coronavirus (HCoV), respiratory syncytial virus (RSV), and human metapneumovirus (HMPV). ResultsFrom 2015 to 2019, a total of 344 ILI cases were tested, of which 192 out of 344 cases (55.81%) were tested positive for single respiratory pathogen. From 2023 to 2024, 1 557 ILI cases were tested, with 572 out of 1 557 cases (36.74%) being positive for single pathogen. From 2023 to 2024, the positive rate of single pathogen in ILI cases was significantly lower than that in 2015‒2019 (χ²=42.66, P<0.001). Specifically, the positive rate of Flu A (χ²=74.43, P<0.001) decreased, while that of HPIV (χ²=8.66, P=0.003) increased, both with statistically significant differences. According to the seasonal pattern, the epidemic intensity of Flu A decreased in summer, while that of HPIV increased in summer and autumn. Demographic results showed statistically significant differences in the positive rates of EV/HRV between genders (χ²=22.38, P<0.001), with males exhibiting a higher positive rate than females. No statistically significant differences were identified in the positive rates of single pathogen among different age groups (χ²=4.42, P=0.110). Nevertheless, statistically significant differences were noted when comparing the positive rates of EV/HRV, Flu A, Flu B and HPIV across different age groups (P<0.05). EV/HRV was more commonly detected in the 15‒<25 age group (10.93%), while Flu A and HPIV had the highest positive rates in the ≥60 age group (21.24% and 4.77%). Flu B had the highest positive rate in the 25‒<60 age group (11.26%). 52.63% of cases with co-infections occurred during winter, with the primary pathogens involved being EV/HRV (9 cases) and HCoV (6 cases). The most prevalent combination of co-infection was Flu A with EV/HRV. ConclusionThe prevalence of respiratory pathogens among ILI cases from 2023 to 2024 exhibited notable fluctuations compared to that from 2015 to 2019. Therefore, influenza surveillance should be strengthened, and attention should also be paid to the prevalence of respiratory pathogens such as HPIV. These findings have profound implications for future research, surveillance, vaccine planning, and public health policy making.

MethodsA single-center， randomized， parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine （TCM） pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group （conventional Western medicine treatment） and an experimental group （Yishen Jiangtang decoction combined with conventional Western medicine treatment）， with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters： Blood urea nitrogen （BUN）， serum creatinine （SCr）， estimated glomerular filtration rate （eGFR）， urinary albumin-to-creatinine ratio （UACR）， fasting blood glucose （FBG）， triglycerides （TG）， total cholesterol （TC）， and low-density lipoprotein cholesterol （LDL-C）. Enzyme-linked immunosorbent assay （ELISA） kits were used to measure serum glucose-regulated protein 78 （GRP78）， serum cysteinyl aspartate-specific protease-3 （Caspase-3）， and serum and urinary transforming growth factor-β₁ （TGF-β₁） levels before and after treatment. TCM symptom scores， TCM syndrome efficacy， and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3， as well as serum and urinary levels of TGF-β1， with renal function， proteinuria， and glucose and lipid metabolism indicators in patients with DKD. In addition， safety indicators were also monitored.

Moreover， the experimental group outperformed the control group in altering the indicators above （P<0.05）. Regarding TCM syndrome efficacy， the total response rate in the experimental group was 83.78%， which was higher than that （57.89%） in the control group （P<0.05）. Regarding overall clinical efficacy， the total response rate in the experimental group was 78.38%， which was higher than that （50.00%） in the control group （P<0.05）. ③ Mechanism outcomes： Compared with baseline levels， both groups showed declined serum levels of GRP78， Caspase-3， and TGF-β₁ and urinary level of TGF-β₁ after treatment （P<0.01）. Moreover， the experimental group showed greater declines than the control group （P<0.05）. The serum levels of GRP78， Caspase-3，and TGF-β₁ and the urinary level of TGF-β₁ in DKD patients showed positive correlations with BUN， SCr， UACR， and FBG and negative correlations with eGFR （P<0.05）. ④ Safety outcomes： Neither group showed drug-related adverse reactions， and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms， correct glucose and lipid metabolism disorders， and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

BACKGROUND:When performing percutaneous minimally invasive transforaminal lumbar interbody fusion to implant an intervertebral cage,due to the narrow operating range of the approach,there is a risk of nerve root injury or poor position of cage. To solve the above problems,a novel mechanical deformable press-fit cage (YP-cage) was invented.OBJECTIVE:To preliminarily evaluate the mechanical strength characteristics of this new lumbar fusion device YP-cage.METHODS:Static axial compression and torsion tests were conducted on 9,11,and 13 mm YP-cages (n=9) and poly (ether ether ketone) (PEEK)-cages (n=9). The force-displacement curves were collected to calculate yield displacement and load,ultimate load displacement and stiffness,yield angular displacement and torque,ultimate load and angle displacement torque and stiffness for comparative analysis. RESULTS AND CONCLUSION:(1) In the static axial compression test,YP-cage was superior to PEEK-cage in terms of stiffness,yield load,ultimate displacement,and load limit in three groups of tests (9,11,13 mm) (P<0.01),but the yield displacement of YP-cage was smaller than that of PEEK-cage (P<0.05). (2) In the static torsion test,there was no significant difference in the ultimate torsion angle between YP-cage and PEEK-cage in 9 mm group. YP-cage was lower thanPEEK-cage in yield torque,yield torsion angle,and ultimate torque (P<0.01),while YP-cage torsional stiffness was greater than PEEK-cage in 9 mm group and 11 mm group (P<0.01). (3) The results show that the novel press-fit mechanical lumbar cage has higher compressive strength than PEEK cage,but the torsional strength is not as good as PEEK-cage.

Objectives:To investigate the clinical efficacy and safety of posterior O-arm navigated internal fixation+osteotomy orthopedic surgery and anterior oblique lumbar interbody fusion(OLIF)+posterior O-arm navi-gated internal fixation in the treatment of patients with degenerative scoliosis.Methods:A retrospective anal-ysis was performed on the 55 patients with degenerative scoliosis who were treated in our hospital between May 2016 and June 2023.According to surgical method,the patients were divided into posterior O-arm navi-gated internal fixation+osteotomy orthopedic group(group A,20 cases)and anterior OLIF+posterior O-arm navi-gated internal fixation group(group B,25 cases).Group A consisted of 8 males and 12 females,aged 47-81(66.4±7.4)years old;Group B consisted of 8 males and 17 females,aged 52-81(67.4±8.2)years old.The pe-rioperative data of the patients were collected,and the visual analogue scale(VAS)score and Oswestry disabil-ity index(ODI)were recorded before operation,at postoperative 1 week and final follow-up to evaluate the clinical efficacy,and full-length spinal X-ray were taken in the standing position at the same time point to measure the coronal Cobb angle,sagittal vertical axis(SVA),lumbar lordosis(LL),intervertebral space height,vertebral fusion rate.The complications were recorded and compared between groups.Results:The patients were followed up for 18-38(26.5±5.3)months in group A and 20-36(24.3±4.2)months in group B,with no statistical difference(P＞0.05).Statistical differences(P＜0.05)were observed between group A and group B in operative time(219.0±25.7min vs 169.4±25.6min),intraoperative blood loss(1087.5±353.1mL vs 672.5±308.6mL),postoperative drainage volume(364.7±22.9mL vs 109.3±25.3mL),postoperative ambulation time(11.0±3.4d vs 6.3±1.8d),and number of blood transfusions(18 vs 8).The VAS scores were 6.2±0.9 points and 1.8±0.8 points in group A at postoperative 1 week and final follow-up respectively,which were 4.4±0.9 and 1.3±0.5 in group B,and group B was lower than group A at the same postoperative time point(P＜0.05).The ODI of group A and group B at postoperative 1 week were(22.8±4.8)％and(19.9±2.9)％,and group B was lower than group A(P＜0.05),while there was no significant difference between the two groups at final follow-up(P＞0.05).At postoperative 1 week and final follow-up,the sagittal SVA of group A was 47.0±1 1.5mm and 43.9±19.7mm,which was 35.2±19.9mm and 30.9±19.9mm in group B,and the sagittal correction in group A was better than that in group B(P＜0.05).There was no statistical difference between the two groups in coronal Cobb angle and LL at postoperative 1 week and final follow-up(P＞0.05).The intervertebral space height of group A was 48.1±8.2mm and 46.1±8.5mm at postoperative 1 week and final follow-up,which was 57.4±5.4mm and 56.3±5.6mm in group B,and group B was better than group A(P＜0.05).There were 2 cases of postoperative cerebrospinal fluid leakage,2 cases of delayed incision healing,1 case of nail and rod fracture,1 case of screw loosening in group A,and the complication rate was 30％(6/20);2 cases in group B had postoperative pain on the anteromedial side of the left thigh,and 2 cases had transient left hip flexion weak-ness,all of which recovered at follow-up,and the complication rate was 16％(4/25).The complication rate was higher in group A than group B(P＜0.05).Both groups had no incision infection or spinal cord injury complications.At final follow-up,the bone graft and fusion device were osseous fusion in both groups.Con-clusions:Both posterior O-arm navigated internal fixation+osteotomy orthopedic surgery and anterior OLIF+posterior O-arm navigated internal fixation can achieve satisfactory clinical efficacy in the treatment of degen-erative scoliosis,the former has better sagittal orthopedic effect,but has the problems of long operative time,large amount of bleeding,long postoperative bed rest,and many complications,while the latter has a similar scoliosis correction,as well as the advantages of minimally invasive,less traumatic,fast recovery and fewer complications,which can provide a new option for the minimally invasive treatment of degenerative scoliosis.

Objective To investigate the expression characteristics of poly(rC)-binding protein 1(PCBP1)in gastric cancer tissues and their clinical significances by bioinformatics analysis combined with experimental verification,and to identify its relationship with STIP1 homology and U-Box containing protein 1(STUB1).Specifically,this study aims to verify the expression patterns of PCBP1 and STUB1 in gastric cancer and determine their relationships with clinicopathological features by immunohistochemistry to provide a theoretical framework as well as potential intervention strategies for gastric cancer.Methods Data of PCBP1 expression in gastric cancer and adjacent tissues were obtained from TIMER 2.0 online analysis website.KEGG pathway enrichment analysis was performed using gastric cancer data(STAD)in the TCGA(the Cancer Genome Atlas)database,and its potential mechanism was determined.The main regulatory factor STUB1 was found in the fer-roptosis regulatory pathway.Subsequently,PCBP1 and STUB1 expressions in 33 cases of gastric cancer tissues and corresponding adjacent tissues were detected by immunohistochemistry.The collected cases were grouped according to different degrees of differentiation,age,gender,tumor size,depth of tumor invasion,TNM stage and pathological morphology.The positive expression rates of PCBP1 and STUB1 were observed.The correlation between the two proteins and the correlation between clinical and pathological features were analyzed by c2 test.Finally,the relationship between PCBP1 and STUB1 and malignancy of gastric cancer was further explored.Results Immunohistochemical results showed that the positive expression rate of PCBP1 in cancer tissues was 69.7%,which was significantly higher than that in adjacent tissues(48.5%).The positive expression rate of STUB1 in cancer tissues was 39.4%,which was lower than that in adjacent tissues(54.5%),statistically significant difference(P<0.05).The positive expression rate of PCBP1 was correlated with tumor differentiation,lymph node metastasis and Lauren classification(P<0.05),but not with patient's age,gender,depth of inva-sion,clinical stage,nerve infiltration,and intravascular tumor thrombus(P>0.05).The positive expression rate of STUB1 was correlated with tumor differentiation,depth of invasion,lymph node metastasis and Lauren classification(P<0.05).The Spearman correlation coefficient between PCBP1(cancer)and STUB1(cancer)was-0.413,with P=0.017(P<0.05),indicating that there was a significant negative correlation between them.Conclusion PCBP1 participates in the malignant progression of gastric cancer by regulating the main regulator STUB1 in the ferroptosis pathway.Theoretically,it provides a new insight into molecular mechanism as well as a potential therapeutic strategy for treating gastric cancer.

ObjectiveTo investigate the influence of entecavir （ETV） versus tenofovir alafenamide fumarate （TAF） on renal function in previously untreated patients with chronic hepatitis B （CHB）. MethodsA retrospective analysis was performed for the clinical data of 167 previously untreated CHB patients who received ETV or TAF treatment for at least 48 weeks at the outpatient service of Department of Infectious Diseases in The First Affiliated Hospital of Nanchang University from September 2019 to November 2023， and according to the antiviral drug used， they were divided into ETV group with 117 patients and TAF group with 50 patients. In order to balance baseline clinical data， propensity score matching （PSM） was used for matching and analysis at a ratio of 2∶1， and the two groups were compared in terms of estimated glomerular filtration rate （eGFR） and the incidence rate of abnormal renal function at week 48. According to eGFR at week 48， the patients were divided into normal renal function group and abnormal renal function group. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the influencing factors for abnormal renal function， and the receiver operating characteristic （ROC） curve was used to assess the performance of each indicator in predicting abnormal renal function. The Kaplan-Meier method was used to analyze the cumulative incidence rate of abnormal renal function， and the log-rank test was used for comparison. The analysis of variance with repeated measures was used to compare the dynamic changes of eGFR during antiviral therapy in CHB patients. ResultsAfter PSM matching， there were 100 patients in the ETV group and 50 patients in the TAF group. There were no significant differences in baseline clinical data between the ETV group and the TAF group （all P>0.05）， with an eGFR level of 112.29±9.92 mL/min/1.73 m² in the ETV group and 114.72±12.15 mL/min/1.73 m² in the TAF group. There was a reduction in eGFR from baseline to week 48 in both groups， and compared with the TAF group at week 48， the ETV group had a significantly lower eGFR （106.42±14.12 mL/min/1.73 m² vs 112.25±13.44 mL/min/1.73 m²， t=-2.422， P=0.017） and a significantly higher incidence rate of abnormal renal function （17.00% vs 4.00%， χ²=5.092， P=0.024）. After the patients were divided into normal renal function group with 131 patients and abnormal renal function group with 19 patients， the univariate analysis showed that there were significant differences between the two groups in age （Z=-2.039， P=0.041）， treatment drug （ETV/TAF） （χ²=5.092， P=0.024）， and baseline eGFR level （t=4.023， P<0.001）， and the multivariate Logistic regression analysis showed that baseline eGFR （odds ratio ［OR］=0.896， 95% confidence interval ［CI］： 0.841 — 0.955， P<0.001） and treatment drug （OR=5.589， 95%CI： 1.136 — 27.492， P=0.034） were independent influencing factors for abnormal renal function. Baseline eGFR had an area under the ROC curve of 0.781 in predicting abnormal renal function in CHB patients， with a cut-off value of 105.24 mL/min/1.73 m²， a sensitivity of 73.68%， and a specificity of 82.44%. The Kaplan-Meier curve analysis showed that the patients with baseline eGFR≤105.24 mL/min/1.73 m² had a significantly higher cumulative incidence rate of abnormal renal function than those with baseline eGFR>105.24 mL/min/1.73 m² （χ²=22.330， P<0.001）， and the ETV group had a significantly higher cumulative incidence rate of abnormal renal function than the TAF group （χ²=4.961， P=0.026）. With the initiation of antiviral therapy， both the ETV group and the TAF group had a significant reduction in eGFR （F=5.259， P<0.001）， but the ETV group only had a significant lower level of eGFR than the TAF group at week 48 （t=-2.422， P=0.017）； both the baseline eGFR≤105.24 mL/min/1.73 m² group and the baseline eGFR>105.24 mL/min/1.73 m² group had a significant reduction in eGFR （F=5.712， P<0.001）， and there was a significant difference in eGFR between the two groups at baseline and weeks 12， 24， 36， and 48 （t=-13.927， -9.780， -8.835， -9.489， and -8.953， all P<0.001）. ConclusionFor CHB patients initially treated with ETV or TAF， ETV antiviral therapy has a higher risk of renal injury than TAF therapy at week 48.

Objective:To compare the anterior long-segment fixation, posterior long-segment fixation, and combined anterior-posterior fixation in the treatment of ankylosing spondylitis with cervical fracture (ASCF).Methods:A retrospective study was conducted to analyze the 153 patients with ASCF who had been treated at Department of Orthopaedics, Peking University Third Hospital and Department of Orthopedics, Luoche Central Hospital between January 2014 and December 2023. The cohort included 86 males and 67 females, with an age of (41.6±11.5) years, a disease duration of (10.0±3.9) years, and an interval from injury to surgery of (3.3±1.4) d. By Frankel's classification for preoperative nerve injury, 57 cases were grade B, 51 grade C, and 45 grade D. Based on the surgical approaches, the patients were divided into 3 groups: an anterior group ( n=63) undergoing the anterior cervical long-segment fixation, a posterior group ( n=51) undergoing the posterior cervical long-segment fixation, and a combination group ( n=39) undergoing combined anterior-posterior cervical fixation. Surgical time, intraoperative blood loss, fracture healing, complications, and changes in Frankel grading for spinal cord injury were compared among the 3 groups. Results:There was no statistically significant difference in the preoperative general data among the 3 groups, indicating comparability ( P > 0.05). All patients were followed up for (33.5±12.0) months after surgery. In the anterior group, the surgical time [(103.0±16.8) min] was significantly shorter than that in the posterior group [(148.4±17.7) min] and that in the combination group [(228.5±23.9) min], the intraoperative blood loss [(92.8±27.8) mL] was significantly less than that in the posterior group [(477.5±109.5) mL] and that in the combination group [(769.5±136.9) mL], and the incidence of complications [9.5% (6/63)] was significantly lower than that in the posterior group [41.2% (21/51)] and that in the combination group [53.8% (21/39)] (all P<0.05). There was no statistically significant difference in the fracture healing time among the 3 groups ( P=0.111). At the last follow-up, X-ray and CT scans showed no loosening or breakage of internal fixation in all the 3 groups. The Frankel grading at the last follow-up: 12 cases of grade C, 15 cases of grade D, and 36 cases of grade E in the anterior group; 3 cases of grade B, 12 cases of grade C, 12 cases of grade D, and 24 cases of grade E in the posterior group; 6 cases of grade C, 12 cases of grade D, and 21 cases of grade E in the combination group. At the last follow-up, all patients showed a significant improvement compared to their Frankel grades before surgery ( P<0.001), but there was no statistically significant difference between the 3 groups ( H=2.238, P=0.327). Conclusions:In the treatment of ASCF, anterior long-segment fixation is advantageous over posterior long-segment fixation and combined anteri-or-posterior fixation due to its shorter surgical time, reduced intraoperative blood loss, and a lower complication incidence. All the 3 surgical approaches demonstrate comparable outcomes in terms of fracture healing time, radiographic stability, and final neurological recovery.
