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 advantages and limitations of transcutaneous electrical acupoint stimulation (TEAS) in the treatment of patients with severe gastrointestinal function injury in intensive care unit (ICU) by analyzing dynamic changes of intestinal fatty acid binding protein (I-FABP), D-lactic acid and citrulline. METHODS: A prospective single-center randomized controlled trial was conducted. Patients with severe gastrointestinal function injury admitted to the ICU from February 2021 to January 2024 were enrolled [age > 18 years old, acute gastrointestinal injury (AGI) grade 2 to 3, stable hemodynamics]. Patients with different AGI grades were randomly assigned in a 1:1 ratio to the TEAS group and the control group using simple randomization. Both groups received conventional treatment and enteral nutrition (EN). In addition, the TEAS group underwent TEAS at the Neiguan and Zusanli points for 30 minutes per session, twice daily for 7 days. Baseline data, including age, gender, underlying diseases, and primary diagnoses, were recorded. Three intestinal biomarkers, such as I-FABP, D-lactic acid, and citrulline were measured before and after 7 days of treatment. EN tolerance indicators and 28 days survival status were documented. The differences in various indicators were compared between the two groups, subgroup analyses were conducted based on AGI grading, and interaction between AGI grade and TEAS were analyzed. The 28-day Kaplan-Meier survival curves were generated for both groups. RESULTS: Finally, 133 patients were included, with 68 in the TEAS group and 65 in the control group. Baseline characteristics were comparable between the two groups. A comparison of the dynamic changes in intestinal biomarkers revealed that the I-FABP level in both groups decreased after treatment compared to pre-treatment, with a more pronounced reduction in the TEAS group. The least square mean difference (LS Mean difference) for the corrected I-FABP level between the two groups during the observation period was -0.23 μg/L [95% confidence interval (95%CI) was -0.45 to -0.01], which was statistically significant (P = 0.041). Additionally, a significant interaction with AGI was observed (P = 0.004). Post-treatment, D-lactic acid level decreased in both groups compared to pre-treatment, with a more significant reduction in the TEAS group. The LS Mean difference for the corrected D-lactic acid level was -0.08 mmol/L (95%CI was -0.11 to -0.05), which was statistically significant (P < 0.001), and the interaction with AGI was also significant (P = 0.005). There was no significant change in citrulline levels between the two groups before and after treatment. The LS Mean difference for the corrected citrulline level was -0.17 μmol/L (95%CI was -1.87 to 1.53), which was not statistically significant (P = 0.845), and no significant interaction with AGI was observed (P = 0.913). Comparison of EN tolerance parameters between the two groups revealed that the TEAS group had a longer total EN time (hours: 72±31 vs. 60±28) and higher total EN calories (kJ: 11 469.23±7 237.34 vs. 6 638.76±5 098.37), as well as a higher 70% target caloric attainment rate (52.9% vs. 32.3%) compared to the control group (all P < 0.05). The incidence of abdominal distension after EN was lower in the TEAS group than that in the control group (23.5% vs. 43.1%, P < 0.05), while the incidence of diarrhea after EN was higher in the TEAS group (22.1% vs. 7.7%, P < 0.05). There were no significantly differences in AGI grade reduction rate, post-EN vomiting/gastric retention rate, incidence of feeding interruption, and 28-day survival rate between the two groups. Furthermore, there were no significantly interaction between these observation measures and AGI. Kaplan-Meier survival analysis showed that there was no significantly difference in 28-day cumulative survival rate between the TEAS group and the control group [Log-Rank test: P = 0.501, hazard ratio (HR) = 0.81, 95%CI was 0.43-1.51), and there was no significantly interaction with AGI (P = 0.702). CONCLUSIONS The advantage of TEAS in the treatment of ICU patients with severe gastrointestinal function injury lies in its ability to reverse intestinal cell necrosis and promote the reconstruction of intestinal barrier function. Additionally, gastrointestinal tolerance is significantly improved, and both the duration and total calories of EN are increased. However, the limitation of TEAS therapy is that it does not promote the recovery of intestinal cell absorption and synthesis function in the target patients. Moreover, it may lead to nutrient solution overload due to improved gastrointestinal tolerance. Furthermore, TEAS does not appear to improve 28-day cumulative survival rate in the target patients.

Objectives:To explore the morphological changes of the superficial and deep thoraolumbar paraspinal muscles on both convex and concave sides during rest and contraction states in patients with mod-erate adolescent idiopathic scoliosis(AIS),and their effects on scoliosis angle,to analyze the relations between scoliosis angle and the morphological changes of paraspinal muscles.Methods:21 AIS patients(thoracic Cobb angle 20°-45°,S-shaped with the main curve in thoracic segment,4 males and 17 females,aged 13.9±1.6 years old)treated in our hospital from July 2020 to December 2023 and 21 healthy subjects(7 males and 14 females,aged 14.6±1.4 years old)were prospectively enrolled.The morphological data of thoracolumbar paraspinal muscles were collected with musculoskeletal ultrasound,including the resting thickness and thick-ness during maximum voluntary isometric contraction(MVIC)of superficial erector spinae(ES)and multifidus(MF)muscles of AIS patients on both convex and concave sides(left and right sides of healthy controls).The differences in resting thickness,contraction thickness,change rate of contraction thickness,and total resting thickness and total contraction thickness(ES+MF)of superficial and deep thoracolumbar paravertebral muscles between the two groups were analyzed,and the structural characteristics of the thoracolumbar paravertebral muscles on the convex and concave sides of AIS were analyzed.The correlation between Cobb angle in tho-racolumbar segment and morphological indexes(resting thickness,contraction thickness change rates)of ES and MF muscles was analyzed,and the influence of scoliosis severity on the morphology of superficial and deep paravertebral muscle was further analyzed.Results:In AIS patients,the mean thoracic Cobb angle were 31.62°±7.68°,and mean lumbar Cobb angle were 19.52°±6.48°.Comparing with healthy controls,patients with AIS were significantly different in resting thickness,contraction thickness and thickness change rates of tho-racic paraspinal muscles on both convex and concave sides,and the resting thickness of ES in thoracic seg-ment on concave side was less than that on the convex side,which of MF was less on the convex side than on the concave side(P＜0.01).The contraction thickness of thoracic MF muscles on the convex and concave sides in S-type AIS patients was smaller than that in healthy controls(P＜0.05),while the contraction thickness of thoracic ES muscles on the convex and concave side wasn't statistically different from that of healthy con-trols,and the contraction thickness change rate of ES muscles on the convex and MF on the concave side of thoracic segment in AIS patients was significantly decreased(P＜0.05).There was no significant difference in the total resting thickness of thoracic(convex and concave)paravertebral muscles(ES+MF)between AIS patients and the corresponding segments(left and right)of control group(P＞0.05),and there was no statistically signifi-cant difference in the total resting thickness of thoracic paravertebral muscle between the convex and concave sides of AIS patients(P＞0.05).The total contraction thickness of thoracic paravertebral muscle(ES+MF)in AIS patients was lower than that in control group(P＜0.05).Compared with the control group,the resting thickness,contraction thickness and thickness change rate of lumbar MF muscle on the convex and concave sides in AIS patients were significantly reduced(P＜0.05),and the contraction thickness change rate of the lumbar ES muscle on the concave side was less than that of the control group(P＜0.05).There were no significant differ-ences in resting thickness and contraction thickness between the convex and concave paravertebral muscles in AIS patients(P＞0.05).The total resting thickness(ES+MF)and total contraction thickness(ES+MF)of lumbar(convex and concave)paraspinal muscles in AIS patients were lower than those in control group(P＜0.05).There was a significant negative correlation between the Cobb angle of the main thoracic curve and the rest-ing thickness of the thoracic MF muscle on the concave and the change rate of the contraction thickness of the thoracic ES muscle on the convex in S-type AIS patients(r=-0.53/-0.45,P＜0.05).There was no signifi-cant correlation between the Cobb angle of lumbar segment and the change rates of the resting thickness and contraction thickness of ES and MF muscles on both convex and concave sides(P＞0.05).Conclusions:In pa-tients with moderate S-type AIS,there are different muscle morphological changes in the paraspinal muscles on both convex and concave sides of the main thoracic curve,and the concave paravertebral muscle is more affected by scoliosis;The contraction function of the bilateral deep core stabilizing muscles in the lumbar re-gion is markedly decreased.Different patterns of superficial and deep muscle atrophy and contractility decline may be a key cause of spinal movement disorder and scoliosis progression in AIS patients.

Background and Aims:According to the Chinese Guidelines for the Diagnosis and Treatment of Colorectal Cancer(2023 Edition),patients with early-stage colorectal cancer who present with high-risk factors require additional radical surgery following endoscopic resection.However,due to the relatively low rate of lymph node metastasis in early colorectal cancer,some patients may not benefit from such supplemental surgery.Therefore,accurately identifying patients who are truly likely to benefit and refining the indications for supplemental surgery are pressing clinical challenges.This study was conducted to investigate the risk factors and distribution patterns of lymph node metastasis following additional radical surgery through retrospectively analyzing a large single-center cohort,thereby providing evidence-based support for clinical decision-making.Methods:Clinicopathologic data were retrospectively reviewed for patients with early-stage colorectal cancer who underwent additional radical surgery at Fudan University Shanghai Cancer Center between 2008 and 2023.Binary Logistic regression and multivariate analyses were performed to identify risk factors associated with lymph node metastasis,and the distribution characteristics of metastatic lymph nodes were further examined.Results:A total of 417 patients were included in the study,with lymph node metastasis confirmed in 36 cases(8.63％)postoperatively.Over time,the number of patients undergoing supplemental surgery increased,while the proportion of cases with residual cancer decreased.Among 243 patients included in the risk factor analysis,univariate analysis indicated that submucosal invasion depth of SM2 or greater,poor tumor differentiation,positive vascular invasion,and tumor location were high-risk factors for lymph node metastasis.Multivariate analysis identified invasion depth(P=0.039)and tumor location(P=0.014)as independent risk factors.Among the metastatic cases,58.3％involved a single lymph node;63.9％of metastases were limited to the first station,and 36.1％extended to the second station,with no metastasis found at the third station.Only four patients had preoperative imaging suggestive of lymph node enlargement.Conclusion:Although the number of supplemental surgeries following endoscopic resection of early-stage colorectal cancer has increased significantly,the actual rate of lymph node metastasis remains low,suggesting a potential risk of overtreatment.Submucosal invasion depth ≥SM2 and tumor location are independent risk factors for metastasis.D2 lymph node dissection is deemed necessary,while the diagnostic value of imaging remains limited.Clinical decisions should prioritize precision and individualized treatment planning.

Objective To provide experimental evidence for selecting acupuncture timing in clinical practice,the optimal time for enhancing the brain effects of electroacupuncture at the Hegu acupoint(LI4)by observing brain imaging data,hemodynamic changes and differences in brain functional connectivity across the twelve traditional Chinese time periods were determined.Methods Thirty-six C57BL/6 mice were randomly divided into 12 groups corresponding to each of the twelve time periods(Zi,Chou,Yin,Mao,Chen,Si,Wu,Wei,Shen,You,Xu,Hai),with 3 mice per group.Each mouse received electroacupuncture stimulation using the same protocol.Brain imaging data and dynamic hemodynamic changes were collected using functional ultrasound imaging(FUS)ultrasound imaging technology every 0.4 s over a total duration of 420 s,covering pre-acupuncture(resting state),during acupuncture(task state),and post-acupuncture(post-task state)phases.The hippocampal region(HIP)was used as the observation point to analyze changes in functional connectivity between HIP and other brain regions before and after acupuncture.Results Compared to other time periods,the Mao group exhibited the largest whole-brain activation area and the highest average activation signal intensity.The hemodynamic signal increase in the hippocampal region was more pronounced,and the post-acupuncture blood flow signal intensity remained significantly higher than the pre-acupuncture resting state.Functional connectivity data revealed that,using 0.2 as the standard value,the Mao group showed the greatest number of altered brain regions before and after acupuncture.Notably,only in the Mao group was there a significant enhancement in connectivity between the bilateral hippocampal regions.Conclusion The immediate effects of electroacupuncture at the Hegu acupoint(LI4)and brain functional connectivity vary significantly across different time periods,aligning with the traditional Chinese medicine theory of meridian qi and blood flow.Mao time is identified as the optimal period.

Objective:To explore the mediating effect of attitudes to aging between intergenerational support and health behavior in elderly stroke patients.Methods:From March 2023 to February 2024, elderly stroke patients hospitalized in the Department of Neurology at Beijing Tongren Hospital, Capital Medical University, were selected as study subjects using convenience sampling. The survey was conducted using the General Information Questionnaire, Attitudes to Ageing Questionnaire (AAQ), Intergenerational Support Scale (ISS), and Stroke Health Behavior Questionnaire (SHBQ). Pearson correlation was employed to analyze the relationships among attitudes to aging, intergenerational support, and health behavior. AMOS 21.0 software was used to construct the structural equation model and verify the mediating effect.Results:A total of 250 questionnaires were distributed, and 243 valid questionnaires were collected, with a valid response rate of 97.20%. The AAQ, ISS, and SHBQ scores of 243 elderly stroke patients were (70.57±9.03), (19.74±3.65), and (71.67±5.50), respectively. Attitudes to aging were positively correlated with both intergenerational support and health behavior ( P<0.05), and intergenerational support was positively correlated with health behavior ( P<0.05). Intergenerational support had a direct positive effect on health behavior (β=0.552), and attitudes to aging had a direct positive effect on health behavior (β=0.632). Attitudes to aging partially mediated the relationship between intergenerational support and health behavior, accounting for 38.12% (0.340/0.892) of the total effect. Conclusions:Attitudes to aging partially mediates the relationship between intergenerational support and health behavior. Improving intergenerational support may foster positive attitudes to aging, thereby promoting the development of healthy behavior among elderly stroke patients.

Purpose To measure the spatial resolution in MRI quality control testing automatically based on the American College of Radiology(ACR)phantom using the support vector machine(SVM)method,and the feasibility,accuracy and measurement speed of this method are explored.Materials and Methods Quality control tests were performed using eight MRI devices at Beijing Friendship Hospital of Capital Medical University.A retrospective study was conducted on 71 MRI quality control test images collected based on ACR phantoms between 2017 and 2019.The images were preprocessed by binarization,extraction region of interest and so on.An SVM-based classification model was constructed for analyzing the spatial resolution of dot arrays in row and column directions.The dataset was randomly split into a training set and a test set.The generalization performance of the classification model in this study was evaluated through accuracy,precision,recall and F1 score on the test set.Comparing the results of spatial resolution measurements obtained by both manual and automatic method,we demonstrated the feasibility and accuracy of the method.Additionally,the time taken for the automatic spatial resolution measurement was recorded.Results In this study,the proposed method of automatically measuring the spatial resolution of ACR phantom test images using SVM was feasible,high accuracy and short time.In classification performance test,the accuracy of the spatial resolution of the row directional latices was 95%,the precision was 100%.The accuracy of the spatial resolution of the column directional latices was 97%,the precision was 100%.Among the test cases,the results of automatic measurements matched those of manual measurements in 13 out of 14 cases.On average,automatic spatial resolution measurement took 0.158 seconds per case.Conclusion This study achieves automatic measurement of spatial resolution in MRI quality control based on the ACR phantom using SVM method.The method demonstrates high accuracy and fast measurement speeds,holding significant implications for future rapid MRI quality control stability testing.

Purpose To explore an automatic detection method for quality control performance indicators of radio frequency coils based on American College of Radiology(ACR)phantom,and verify its accuracy stability and computational efficiency.Materials and Methods A retrospective study was conducted on 50 quality control images collected based on ACR phantom in Beijing Friendship Hospital,Capital Medical University from May 2017 to July 2019.The measurement and calculation methods of signal noise ratio(SNR),percent image uniformity(PIU)and percent signal ghosting(PSG)were used to automatically calculate the above indicators using a self-designed program in Python.A simple linear regression analysis on the automatically calculated SNR,PSG and PIU values compared to the manually measured results was performed,and Bland-Altman analysis was used to calculate the percentage difference to evaluate the consistency and bias between the performance indicators calculated by the two methods.The time consumption of two detection methods was compared to verify their computational complexity and efficiency.Results There was a strong correlation between the performance indicators SNR,PSG and PIU of radio frequency coils measured and calculated automatically and manually(r=0.991 4,0.992 8 and 0.909 8,all P<0.0001).The Bland-Altman results showed that most of the data fall within the 95%confidence interval and were evenly distributed.In terms of computational complexity and efficiency,compared to the complex manual delineation and calculation of 2-3 minutes per case,automatic detection could simultaneously obtain SNR,PSG and PIU values in less than 1 second.Conclusion The automatic and manual measurement methods have good consistency,and the automatic detection method is easy to operate,which is helpful for the daily quality control work and performance monitoring of radio frequency coils.

Objective:To evaluate the efficacy of eradication therapy based on potassium-competitive acid blocker (P-CAB) for Helicobacter pylori( HP) infection in re-eradication therapy (the second-line therapy treatment after initial eradication failure of HP infection) and determine whether it can achieve the ideal eradication rate (90%). Methods:From January 2022 to December 2023, the clinical data of patients who received vonoprazan-based HP re-eradication therapy were collected in Department of Gastroenterology, the First Affiliated Hospital of Soochow University. The patients were divided into 4 groups according to their different HP treatment regimens, including VAMB group (vonoprazan 20 mg, quaque die( qd)+ amoxicillin 1 g, bis in die( bid)+ minocycline 100 mg, bid+ potassium bismuth citrate 220 mg, bid; 156 cases), VA group (vonoprazan 20 mg, bid+ amoxicillin 1 g, ter in die( tid); 44 cases), VMFB group (vonoprazan 20 mg qd+ minocycline 100 mg, bid+ furazolidone 100 mg, bid+ potassium bismuth citrate 220 mg, bid; 42 cases), and VAFB group (vonoprazan 20 mg, qd+ amoxicillin 1 g, bid+ furazolidone 100 mg, bid + potassium bismuth citrate 220 mg, bid; 13 cases). All the 4 groups of patients took the medication for 14 days. The 13C or 14C urea breath test would be conducted 4 weeks after the treatment. The overall eradication rate to evaluate the treatment efficacy. The eradication rate and adverse reaction rate were calculated for each group, and the eradication rates and adverse reaction rates between groups were compared using the chi-square test or Fisher′s exact test. Results:The total eradication rate of HP infection based on P-CAB therapy was 91.8% (234/255), and the total adverse reaction rate was 5.1% (13/255). The eradication rate and adverse reaction rate were 92.9% (145/156) and 3.2% (5/156) in the VAMB group, 84.1% (37/44) and 0 in the VA group 95.2% (40/42) and 11.9% (5/42) in the VMFB group, 12/13 and 3/13 in the VAFB group, respectively. Additionally, there was no statistical difference in the eradication rate among the 4 groups (Fisher′s exact test, P=0.227), but there was a statistical difference in the adverse reaction rates (Fisher′s exact test, P=0.002), and the adverse reaction rate of the VAFB group was higher than that of VAMB and VA groups and the differences were statistically significant (both Fisher′s excact test, P=0.016 and 0.010). Conclusions:The total HP re-eradication rate based on P-CAB therapies can reach 91.8%, achieving the ideal eradication rate of HP infection. The VA therapeutic regimen has the lowest incidence of adverse reactions, representing a novel therapeutic option for HP re-eradication.
