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 investigate the change of interleukin （IL）-18 and Th1， Th2 of CD3⁺CD8^- T helper lymphocytes in pediatric liver transplantation with cytomegalovirus （CMV） infection. MethodsA total of 40 pediatric patients who underwent pediatric liver transplantation were collected. Patients were divided into the CMV group （n=20） and the non-infected group （n=20） according to whether CMV infection occurred. The plasma IL-18 levels were determined by enzyme-linked immunosorbent assay （ELISA）. The expression percentage of IFN-γ and IL-10 of CD3⁺CD8^- T lymphocytes （Th1 and Th2） in peripheral blood were determined with flow cytometry. ResultsThe expression level of plasma IL-18 significantly increased in the CMV group compared with that in non-infected group （P<0.01）. The expression percentage of Th1 in peripheral blood significantly decreased in the CMV group compared with that in non-infected group （P<0.01）. No significant difference was found in the expression percentage of Th2 between CMV group and non-infected group. IL-18 levels were negatively correlated with the Th1 （P<0.05）. ConclusionThe elevated IL-18 levels along with polarized Th 1 subsets’ imbalance involves in the pathogenesis of CMV infection in pediatric liver transplantation.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Objective:To investigate the changes of respiratory function and lung volume after bariatric surgery using spiral CT three-dimensional imaging technology.Methods:Using the prospective study method, the medical records of 30 subjects undergoing sleeve gastrectomy (LSG) in the Eighth Department of General Surgery, the Second Hospital of Hebei Medical University from Jan. 2023 to Jun. 2024 were collected. Among them, 12 were males and 18 were females, aged from 20 to 45 years, with the average age of 31.1 years old. Chest CT scans were completed within 1 week before surgery and 6 months after surgery. The subject′s CT plain scan reconstructed thin-layer images of the mediastinal window were transferred to a GE workstation, and the lung volumes of both lungs and each lobe and the tracheal wall area of the five bronchial segments (RB1, RB4, RB10, LB1 + 2 and LB10) were calculated as a percentage of the airway cross-sectional area (WA%), and the posterior intercostal position corresponding to the diaphragm was recorded. Paired t-test and rank-sum test were used to compare preoperative and postoperative differences.Results:Compared with pre-operation, the subject′s body mass index decreased significantly 6 months after bariatric surgery [(42.22±7.31) kg/m 2vs (30.12±5.59) kg/m 2,t=7.31, P<0.001)]. Except for left lower lobe [(1.15±0.23) L vs (1.27±0.24) L, t=1.97, P=0.054] and right middle lobe [(0.57±0.16) L vs (0.83±0.16) L, t=1.38, P=0.172], the remaining lung parts were significantly larger after surgery than before surgery: right upper lobe [(0.80±0.17) L vs (0.94±0.19) L, t=2.79, P=0.007], right lower lobe [(1.08±0.14) L vs (1.22±0.19) L, t=3.23, P=0.002], left upper lobe [(1.12±0.20) L vs (1.24±0.23) L, t=2.26, P=0.014]. Overall, right lung volume [(2.44±0.33) L vs (2.79±0.41) L, t=3.62, P=0.001], left lung volume [(2.27±0.36) L vs (2.52±0.39) L, t=2.53, P=0.014] and total lung volume [(4.71±0.60) L vs (5.30±0.71) L, t=3.48, P=0.001] all increased significantly at 6 months after surgery compared with before surgery. All five segments of bronchus (WA%) were significantly reduced after surgery than before surgery: RB1: [(62.82±4.66) vs (66.85±3.99), t=3.60, P=0.001]; RB4: [(61.24±5.28) vs (64.31±5.51), t=2.20, P=0.031]; RB10: [(60.03±4.64) vs (62.97±5.73), t=2.18, P=0.033]; LB1+ 2: [(63.61±5.05) vs (67.90±4.30), t=3.54, P=0.001]; LB10: [(58.73±6.49) vs (62.01±5.06), t=2.17, P=0.034)]. The posterior intercostal position corresponding to the diaphragm dropped from an average of 7-8 intercostal spaces to 8-9 intercostal spaces, with a significant difference (rank mean 22.77 vs 38.23, Z=-3.67, P<0.001). Conclusion:Bariatric surgery can significantly reduce weight, reduce the pressure of chest and abdominal, improve lung compliance, reduce the internal pressure of the chest, lower the diaphragm, expand the lung volume and airway cross-sectional area, restore the original airway anatomy and respiratory physiology, so it can effectively improve the respiratory function and lung structure abnormalities caused by obesity.

Objective To compare the clinical effect between cannulated compression countersunk head screws(CS)and anatomical locking compression hook plate(LCP)for fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ.Methods A total of 60 patients with fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ from May 2021 to May 2023 were retrospectively analyzed.Of them,20 patients were treated by internal fixation with cannulated compression countersunk head screws(CS group),and other 40 patients were treated by internal fixation with anatomical locking compression hook plate(LCP group).The postoperative therapeutic effects were evaluated by using the Visual Analogue Scale(VAS)and the American Orthopaedic Foot and Ankle Society(AOFAS)Midfoot Scale.Incidences of postoperative complications were also recorded.Results The operations were successfully completed in all the 60 patients.The operation time in the CS group was shorter than that in the LCP group[37(15-74)min vs.50.5(28-102)min,P=0.002].The VAS score in the CS group immediately after surgery was lower than that in the LCP group[3(2-5)vs.4(2-5),P=0.004],and there was no significant difference between the two groups at 3,6,and 12 months after surgery and at the last follow-up(P＞0.05).At the 3rd month after operation,the AOFAS score in the CS group was better than that in the LCP group[52(23-62)vs.49(23-62),P=0.038],and there was no significant difference between the two groups at 6 and 12 months after surgery and at the last follow-up(P＞0.05).In the LCP group,there were 1 case of superficial wound infection,3 cases of long-term chronic pain,6 cases of foreign body sensation,5 cases of removal of the internal fixation by a second operation after one year postoperatively.In the CS group,there was only 1 case of foreign body sensation.Conclusions Both cannulated compression countersunk head screws and anatomical locking compression hook plate can effectively fix fractures of proximal fifth metatarsal bone at Lawrence zone Ⅰ.Compared with anatomical locking compression hook plate,cannulated compression countersunk head screws can shorten operation time,reduce postoperative pain,and facilitate early functional rehabilitation.

Objective:To compare the impacts of external fixation of different durations on rehabilitation outcomes after open repair of acute Achilles tendon rupture.Methods:A prospective cohort study was conducted to analyze the clinical data of patients with unilateral acute closed Achilles tendon rupture admitted to Peking University Third Hospital from August 2020 to August 2023. Patients were divided into Group A ( n=96), Group B ( n=347), Group C ( n=346), and Group D ( n=105) based on different postoperative immobilization durations (0, 2, 4 and 6 weeks, respectively). After all the patients received identical open repair procedure, Group A was rehabilitated immediately but the other groups were rehabilitated with the same protocol after removal of the external fixation. Four groups were compared in terms of recovery time of one-leg heel-rise height (OHRH), recovery time of light exercise (LE) in brisk walking and jogging and recovery time of range of motion (ROM). Visual analogue scale (VAS) scores were also compared at 2, 4, 6 and 8 weeks postoperatively. Achilles tendon total rupture score (ATRS) and American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores were evaluated at 6, 8, 10, 12, 14 and 16 weeks postoperatively.

Conclusion:For patients with unilateral acute Achilles tendon rupture, two weeks of postoperative external fixation after open repair can shorten the time of returning sports, alleviate pain, and promote functional recovery, without increasing the risk of complications.

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.

Objective To evaluate the clinical efficacy and safety of Huoxue Jiedu Prescription in the treatment of polycythemia vera with heat toxicity and blood stasis syndrome.Methods Totally 155 patients of polycythemia vera with heat toxicity and blood stasis syndrome from 5 hospitals including Langfang Traditional Chinese Medicine Hospital from October 2022 to March 2024 were collected.Patients were divided into an observation group(79 cases)and control group(76 cases)using a random number table method.Both groups received conventional Western medicine treatment.The observation group was given Huoxue Jiedu Prescription,one dosage per day,taken orally twice a day;both groups received one treatment course of one month,and three treatment courses were observed.The efficacy of Western medicine and TCM syndromes was observed,and the total symptom assessment scale of myeloproliferative neoplasms(MPN-10)scores,hematological indicators,coagulation function before and after treatment were compared.The safety indicators of the two groups were monitored.Results The control group and observation group lost 2 and 4 cases,respectively.The total effective rate of Western medicine in the observation group was 90.67%(68/75),while the control group was 67.57%(50/74),with statistical significance(P<0.01).The total effective rate of TCM syndromes in the observation group was 94.67%(71/75),while in the control group was 71.62%(53/74),with statistical significance(P<0.01).Compared with before treatment,the total score of MPN-10 in both groups significantly decreased(P<0.05);after treatment,the total score of MPN-10 in the observation group was lower than that in the control group(P<0.05).Compared with before treatment,both groups showed significant reductions in hemoglobin,white blood cell count,hematocrit and platelet count after treatment(P<0.05);after treatment,the above hematological indicators in the observation group were better than those in the control group(P<0.05).Compared with before treatment,the levels of D-dimer and fibrinogen in both groups significantly decreased after treatment,and the activated partial thromboplastin time and prothrombin time were significantly shortened(P<0.05);after treatment,the observation group showed better improvement in the coagulation function indicators compared to the control group(P<0.05).There were no significant adverse reactions in the two groups.Conclusion Huoxue Jiedu Prescription can improve clinical efficacy of polycythemia vera with heat toxicity and blood stasis syndrome,improve hematological indexes,reduce coagulation indexes,and has good safety.

Objective:To systematically review risk prediction models for frailty in maintenance hemodialysis (MHD) patients.Methods:Relevant literature on frailty risk prediction models for MHD patients were retrieved from PubMed, Web of Science, Embase, Cochrane Library, CINHAL, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc from inception to March 25, 2024. Two researchers independently screened the literature and extracted data. The PROBAST tool was used to assess the methodological quality of the prediction models. Meta-analysis of predictive factors was conducted using Stata 16.0 software.Results:A total of 13 studies were included, comprising 19 frailty risk prediction models for MHD patients. All studies exhibited a high risk of bias. Six studies conducted internal validation, and three studies conducted external validation. The area under the receiver operating characteristic curve ( AUC) of the included prediction models ranged from 0.720 to 0.998. Meta-analysis revealed that age [ OR=1.149, 95% CI (1.070, 1.234), P<0.001], female gender [ OR=4.472, 95% CI (1.799, 11.117), P<0.001], nutritional score [ OR=2.650, 95% CI (1.010, 6.970), P=0.048], comorbidities [ OR=1.990, 95% CI (1.500, 2.650), P<0.001], and serum albumin [ OR=0.830, 95% CI (0.790, 0.880), P<0.001] were significant influencing factors for frailty in MHD patients. Conclusions:Risk prediction models for frailty in MHD patients are still in the research stage. Healthcare professionals should pay close attention to frailty risks in older patients, females, those with malnutrition, comorbidities, and low serum albumin levels, and implement timely interventions.

Objective:To explore the potential causal relationships between major depressive disorder(MDD),anxiety disorder(AD)and various highly prevalent cancers from the genetic perspective.Methods:Sum-mary statistics from large-scale genome-wide association studies(GW AS)were analyzed using a bidirectional two-sample Mendelian randomization(MR)approach.The inverse variance weighting method(IVW)was usedas the main analytical approach.The intercept term of MR-Egger regression and the MR-PRESSO method were adopted for the pleiotropy test.Results:The IVW analysis revealed potential causal relationships between MDD and breast cancer[OR(95％CI):1.11(1.01-1.22),P＜0.05],AD and lung cancer[OR(95％CI):1.30(1.02-1.65),P＜0.05],and between colon cancer and MDD[OR(95％CI):1.05(1.00-1.11),P＜0.05].The results of the pleiotropy test showed that the intercept terms of the MR-Egger regression were not statistically significant,indica-ting the absence of pleiotropy.The MR-PRESSO method detected outliers only in the relationship between MDD and breast cancer.The association between MDD and breast cancer remained significant after correction for outliers[OR(95％CI):1.10(1.03-1.17),P＜0.05].Conclusion:The study suggests that MDD may be a risk factor for breast cancer,AD may increase the risk factor for lung cancer,and colon cancer may elevate the risk factor of MDD.Moreover,the possibility of reverse causal relationships has been excluded in all these cases.
