ObjectiveTo explore the possible mechanisms of Shujin Jiannao Formula （舒筋健脑方） for cerebral palsy. MethodsThirty 7-day-old SD rats were randomly divided into normal group， model group， and Shujin Jiannao Formula group， with 10 rats in each group. The model group and Shujin Jiannao Formula group established a cerebral palsy model by the classic Rice-Vannucci method. After successful modeling， rats in Shujin Jiannao Formula group were given Shujin Jiannao Formula 16 g/（kg·d） by gavage， while the normal group and model group were given normal saline 10 ml/（kg·d） by gavage once a day. After one week of intervention， the rats' body weight was measured， and Zea-Longa scores， the righting reflex test， and the hindlimb suspension test were conducted for assessment； hematoxylin-eosin （HE） staining and Nissl staining were used to observe pathological changes in brain tissue， and the number of Nissl-positive neurons was counted； enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of inflammatory cytokines in the brain tissue， specifically interleukin-1β （IL-1β） and tumor necrosis factor-α （TNF-α）； immunofluorescence was used to detect the expression levels of neurofilament protein 200 （NF200） and myelin basic protein （MBP） in brain tissue； Western Blot analysis was conducted to determine the protein levels of phosphoinositide 3-kinase （PI3K）， protein kinase B （Akt/PKB/Rac）， and mammalian target of rapamycin （mTOR） in brain tissue. ResultsCompared with the normal group， rats in the model group showed significantly higher Zea-Longa scores and lower scores in the hindlimb suspension test （P＜0.01）； pathological findings revealed loose structure in the cerebral cortex， hippocampal atrophy， and neuronal damage in brain tissue. Levels of IL-1β and TNF-α elevated， and the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region reduced， and immunofluorescence intensity of NF200 and MBP， as well as protein expression levels of PI3K and mTOR， significantly decreased （P＜0.05 or P＜0.01）. Compared with the model group， rats in Shujin Jiannao Formula group showed decreased Zea-Longa scores and increased hindlimb suspension test scores （P＜0.05）； pathological damage in brain tissue alleviated， levels of IL-1β and TNF-α reduced， the number of Nissl-stained positive neurons in the cortex and hippocampal CA1 region increased， and the immunofluorescence intensity of NF200 and MBP， as well as the protein levels of PI3K and mTOR， significantly elevated （P＜0.05 or P＜0.01）. There were no statistically significant differences among the groups in body weight， body-turning time， or AKT protein levels in brain tissue （P＞0.05）. ConclusionShujin Jiannao Formula can improve the neurological function of rats with cerebral palsy， exert neurorestorative effects， and its mechanism of action may be related to the reduction of inflammatory response in brain tissue and the activation of the PI3K/AKT/mTOR signaling pathway.

Objective To evaluate the efficacy and safety of Qixian Tongluo Formula in the treatment of post-cerebral infarction paralysis with kidney deficiency and blood stasis syndrome,and to preliminarily explore the molecular mechanism of Qixian Tongluo Formula in improving impaired motor function from the perspective of cross-kingdom regulation of Chinese medicine microRNA(miRNA).Methods A pragmatic randomized controlled trial was conducted with 102 patients in the recovery period of post-cerebral infarction paralysis with kidney deficiency and blood stasis syndrome in our hospital.Patients were randomly divided into trial group and control group,with 51 cases in each group.The control group received standard Western medicine standard treatment,while the trial group received Qixian Tongluo Formula in addition to the standard treatment,with one dose per day,boiled in water,and taken warm after breakfast and dinner for a course of 2 months.The disability rate was used as the main efficacy indicator,and the incidence of adverse reactions was used as a safety indicator.miRNA from patient serum and Qixian Tongluo decoction were extracted respectively,and high-throughput sequencing was performed.The two sequences were compared to screen out the cross-kingdom gene transfer of Chinese medicine miRNA.Finally,its target genes of miRNA were predicted,and GO function and KEGG pathway enrichment analysis were carried out.Results A total of 67 patients completed the clinical trial,including 36 cases in the trial group and 31 cases in the control group;The disability rate in the trial group(13.9%)was lower than that in the control group(35.5%)(P<0.05);The incidence of adverse reactions was similar between the trial group(7.69%)and the control group(6.06%)(P>0.05);A total of 9530 Qixian Tongluo decoction miRNA sequences were screened,with 150 potentially involved in cross-kingdom gene transfer,including families such as miR-15 and miR-17;According to the target gene prediction of the top 10 miRNAs in cross-kingdom gene transfer of Chinese medicine,345 overlapping target genes were obtained;GO functional enrichment analysis revealed 16 biological processes,7 cellular components,and 2 molecular functions among the top 25 enriched functions,while KEGG pathway analysis mainly focused on the transforming growth factor-βsignaling pathway,neurotrophin signaling pathway,which are closely related to neural repair and functional recovery processes such as glial scar formation and synaptic plasticity after cerebral ischemia.Conclusion Qixian Tongluo Formula can significantly improve the functional independence level of patients with kidney deficiency and blood stasis syndrome in the recovery period of paralysis after cerebral infarction,offering a safe and effective treatment option for these patients;There were a large number of miRNAs in Qixian Tongluo decoction,some of which could cross-kingdom transferred into the human blood circulation,and promote the recovery of motor function in patients with cerebral infarction through multi-target,multi link and multi pathway gene network regulation.This study provides a new idea for subsequent clinical and basic research.

Objective:To investigate the impact of coronary angiography-derived index of microcirculatory resistance (caIMR) on the long-term prognosis of patients with coronary heart disease (CHD) undergoing elective percutaneous coronary intervention (PCI).Methods:The study was a retrospective cohort study conducted at a single centre. Patients who successfully underwent elective PCI with pre-and post-PCI caIMR measurements in Peking University First Hospital between August 2013 and December 2020 were included. Then patients were categorised into three groups based on pre-and post-PCI caIMR: post-PCI caIMR<25 U group, pre-PCI caIMR<25 U and post-PCI caIMR≥25 U group, and both pre-and post-PCI caIMR≥25 U group. Collected clinical data of patients, including comorbid diabetes mellitus.The primary endpoint was a composite endpoint, defined as a composite of all-cause death, non-fatal myocardial infarction, and any revascularisation. The association between caIMR-based groupings and clinical outcomes was analysed using Cox proportional hazards regression models.Results:A total of 625 patients who underwent successful elective PCI were included in the study, among whom 294 (47.0%) had stable angina. The age was (64.5±10.1) years, and 440 (70.4%) patients were male. Over a median follow-up of 3.69 (1.80, 5.80) years, 122 patients (19.5%) experienced composite endpoint events. Post-PCI caIMR≥25 U in combination with diabetes mellitus was associated with an increased risk of the composite endpoint compared to those with post-PCI caIMR<25 U and without diabetes mellitus (adjusted HR=2.13, 95% CI 1.17-3.88, P=0.014). In the combined analysis, compared with post-PCI caIMR<25 U group, those with both pre-and post-PCI caIMR≥25 U had higher risks of composite endpoint (adjusted HR=2.01, 95% CI 1.18-3.43, P=0.010) and any revascularisation (adjusted HR=2.12, 95% CI 1.17-3.84, P=0.013). The pre-PCI caIMR<25 U and post-PCI caIMR≥25 U group showed no statistically significant differences in any of the endpoints compared to post-PCI caIMR<25 U group. Conclusions:Integrated pre-and post-procedural assessment of caIMR may enhance risk stratification in patients with coronary heart disease. Persistent coronary microvascular dysfunction present both before and after PCI, as measured by caIMR, serves as an independent risk factor for adverse events in patients with coronary heart disease undergoing elective PCI.

Objective:To investigate the impact and clinical value of preoperative intra-aortic balloon pump(IABP)placement on the occurrence of postoperative atrial fibrillation(POAF)in elderly high-risk patients with coronary artery disease undergoing off-pump coronary artery bypass grafting(CABG).Methods:A retrospective cohort study was conducted, selecting 128 elderly(age≥60 years)patients with coronary artery disease who underwent isolated off-pump CABG and met high-risk criteria(≥2 high-risk factors)at Beijing Tongren Hospital.According to the occurrence of POAF, patients were divided into the POAF group(38 cases)and the non-POAF group(90 cases). Preoperative baseline data, preoperative IABP usage, intraoperative and postoperative indicators were collected and compared between the two groups.Univariate analysis was used to screen for differential variables, and multivariate logistic regression analysis was performed to identify the independent risk factors for POAF, focusing on the role and impact of preoperative IABP placement on POAF occurrence.Results:Among the 128 patients included, the incidence of POAF in patients with preoperative IABP placement was lower than that in patients without preoperative IABP placement[12.12%(4/33) vs.35.79%(34/95), χ2=6.512, P=0.011]; the preoperative IABP usage rate in the POAF group was significantly lower than that in the non-POAF group[10.53%(4/38) vs.32.22%(29/90), χ2=5.488, P=0.019]; the proportion of patients with preoperative left ventricular ejection fraction(LVEF)<40% in the POAF group was significantly higher than that in the non-POAF group[23.68%(9/38) vs.10.00%(9/90), χ2=4.140, P=0.042]; and the preoperative creatinine level in the POAF group was also significantly higher than that in the non-POAF group[(90.62±29.45)μmol/L vs.(81.31±20.18)μmol/L, t=2.066, P=0.041]. Multivariate logistic regression analysis showed that preoperative LVEF<40% was an independent risk factor for POAF occurrence( OR=11.862, 95% CI: 1.083-129.875, P=0.043), while preoperative IABP placement was an independent protective factor for POAF occurrence( OR=0.095, 95% CI: 0.016~0.583, P=0.011). The comparison of intraoperative and postoperative indicators between the two groups showed that multiple indicators in the POAF group were significantly worse than those in the non-POAF group.In terms of intraoperative indicators, the mean graft blood flow(mGF)of the graft vessels in the POAF group was lower[(18.25±8.84)ml/min vs.(21.24±7.13)ml/min, t=2.015, P=0.046], while the pulsatility index(PI)was higher(2.64±1.36 vs.2.18±1.07, t=2.045, P=0.043). In terms of postoperative laboratory indicators, the level of cardiac troponin I(cTnI)on the first postoperative day in the POAF group[(15.69±11.32)μg/L vs.(11.46±10.07)μg/L, t=2.092, P=0.038], the highest postoperative creatinine level[(128.23±74.29)μmol/L vs.(96.18±48.32)μmol/L, t=2.897, P=0.004], and the highest blood lactic acid level within 24 hours[(1.78±0.53)mmol/L vs.(1.54±0.62)mmol/L, t=2.085, P=0.039]were all significantly higher.In terms of postoperative recovery indicators, the duration of vasoactive drug use[(46.41±32.08)h vs.(36.21±22.39)h, t=2.058, P=0.042], mechanical ventilation time[(16.72±11.64)h vs.(12.19±9.68)h, t=2.275, P=0.025], and intensive care unit(ICU)stay time[(73.48±60.20)h vs.(54.89±39.29)h, t=2.070, P=0.040]in the POAF group were all significantly longer.The LVEF before discharge in the POAF group was also significantly lower than that in the non-POAF group[(43.08±16.24)% vs.(48.49±13.08)%, t=1.986, P=0.049]. Conclusions:Preoperative LVEF<40% is an independent risk factor for POAF occurrence after off-pump CABG in elderly high-risk patients with coronary artery disease, and preoperative prophylactic IABP placement can significantly reduce the occurrence of POAF in this population.

Objective:To analyze the influencing factors of knee joint stiffness in patients with tibial plateau fractures after arthroscopy and construct a predictive model.Methods:The clinical data of 154 patients with tibial plateau fractures from June 2020 to May 2023 in Xi'an Daxing Hospital were retrospectively analyzed. All patients were treated with arthroscopic assisted internal fixation surgery. The gender, age, body weight, fracture cause, Schatzker classification, osteoporosis, meniscus and ligament structure injury, lower limb malalignment, bone graft, knee extension device injury, internal fixation method, external fixation time, heterotopic ossification, Tscherne classification, drainage tube placement, debridement times, operation opportunity and anesthesia method were recorded. The patients were followed up for 1 year, and the occurrence of knee joint stiffness was recorded. The patients were divided into knee joint stiffness group and normal knee joint group. Multivariate Logistic regression was used to analyze the independent risk factors of knee joint stiffness after arthroscopy in patients with tibial plateau fractures. R language software package was used to construct the nomogram model for predicting the knee joint stiffness after arthroscopy in patients with tibial plateau fractures, calibration curve was drawn, and the Bootstrap method was used to verify the model discrimination. The predictive value of model was evaluated by the receiver operating characteristics (ROC) curve.Results:Among 154 patients with tibial plateau fractures, 28 patients developed knee joint stiffness after arthroscopy (knee joint stiffness group), with an incidence rate of 18.18%; 126 patients had normal knee joints (normal knee joint group). The proportions of obesity, meniscus and ligament structure injury, knee extension device injury, lower limb malalignment and heterotopic ossification in knee joint stiffness group were significantly higher than those in normal knee joint group, and there were statistical differences ( P<0.05 or <0.01); there were no statistical differences in gender composition, age, fracture cause, osteoporosis, Schatzker classification, bone graft, internal fixation method, external fixation time, Tscherne classification, drainage tube placement, debridement times, operation opportunity and anesthesia method between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that obesity, meniscus and ligament structure injury, knee extension device injury, lower limb malalignment and heterotopic ossification were independent risk factors for knee joint stiffness after arthroscopy in patients with tibial plateau fractures ( OR = 5.387, 4.613, 3.308, 3.178 and 4.579; 95% CI 1.207 to 24.034, 1.447 to 14.709, 1.063 to 10.291, 1.155 to 8.745 and 1.540 to 13.613; P<0.05 or <0.01). The body weight, meniscus and ligament structure injury, knee extension device injury, lower limb malalignment and heterotopic ossification were used as predictors to construct a nomogram model for predicting the knee joint stiffness after arthroscopy in patients with tibial plateau fractures. The calibration curve analysis result showed that the theoretical curve was basically consistent with the actual curve trend trajectory ( C- index = 0.861). The ROC curve analysis result showed that the model for predicting the knee joint stiffness after arthroscopy in patients with tibial plateau fractures had good accuracy (area under curve was 0.861), with the sensitivity of 92.9% and specificity of 73.0%. Conclusions:The patients with tibial plateau fractures have the risk of knee joint stiffness after arthroscopy, which may be related to patient obesity, meniscus and ligament structure injury, knee extension device injury, lower limb malalignment and heterotopic ossification. Based on these risk factors, a column chart risk prediction model can be constructed to visualize the risk and have certain predictive value for knee joint stiffness within 1 year after surgery.

BACKGROUND: The American Heart Association recently released a new cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the association between LE8 scores and the risk of chronic kidney disease (CKD) remains uncertain. We aimed to explore the association of LE8 scores with new-onset CKD and examine whether socioeconomic deprivation and genetic risk modify this association. METHODS: A total of 286,908 participants from UK Biobank and without prior CKD were included between 2006 and 2010. CVH was categorized using LE8 scores: low (LE8 scores <50), moderate (LE8 scores ≥50 but <80), and high (LE8 scores ≥80). The study outcome was new-onset CKD, ascertained by data linkage with primary care, hospital inpatient, and death data. Cox proportional hazard regression models were used to investigate the association between CVH categories and new-onset CKD. RESULTS: During a median follow-up of 12.5 years, 8857 (3.1%) participants developed new-onset CKD. Compared to the low CVH group, the moderate (adjusted hazards ratio [HR], 0.50; 95% confidence interval [CI]: 0.47-0.53) and high CVH (adjusted HR, 0.31; 95% CI: 0.27-0.34) groups had a significantly lower risk of developing new-onset CKD. The population-attributable risk associated with high vs. intermediate or low CVH scores was 40.3%. Participants who were least deprived ( vs.  most deprived; adjusted HR, 0.75; 95% CI: 0.71-0.79) and with low genetic risk of CKD ( vs.  high genetic risk; adjusted HR, 0.89; 95% CI: 0.85-0.94) had a significantly lower risk of developing new-onset CKD. However, socioeconomic deprivation and genetic risks of CKD did not significantly modify the relationship between LE8 scores and new-onset CKD (both P -interaction >0.05). CONCLUSION Achieving a higher LE8 score was associated with a lower risk of developing new-onset CKD, regardless of socioeconomic deprivation and genetic risks of CKD.
