Evidence serves as the driving force shifting medical practice from empirical medicine towards evidence-based medicine. In the current era of information explosion, it is challenging for clinical surgeons to extract evidence from the vast pool of primary research literature to address clinical issues. Literature reviews, as a form of synthesized evidence, are particularly crucial for precise and efficient evidence utilization. A new form of review within the framework of evidence-based medicine, systematic reviews, also has widespread application in the surgical domain. With the development of methodological approaches in evidence-based medicine, the types of systematic reviews continue to diversify. This paper outlines and summarizes the common types and methodologies of systematic reviews in the surgical field, aiming to provide a clear framework for surgical practitioners to select evidence for both confirming and innovating clinical practices in specific clinical challenges.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

Objective To investigate the dynamic imaging features of a group of patients with anti-glutamic acid decarboxylase 65 （GAD65） antibody-associated neurological syndromes. Methods A retrospective analysis was performed for related data of the patients who were diagnosed with anti-GAD65 antibody-associated autoimmune neurological syndromes in The Second Hospital of Hebei Medical University from January 2018 to December 2021，including clinical features，treatment outcomes，and cranial magnetic resonance imaging （MRI） features at baseline and during follow-up. Results A total of 15 patients were enrolled，among whom there were 8 female patients and 7 male patients，with an age of onset of 28-72 years. The clinical syndromes included limbic encephalitis in 2 patients，temporal lobe epilepsy in 3 patients，and seizures in 7 patients，accounting for 80%，as well as stiff-person syndrome in 1 patient （6.67%） and cerebellar ataxia in 2 patients （13.3%）. Imaging findings showed that of all 15 patients，14 （93.3%） had brain atrophy at initial diagnosis，and only 1 young patient had no brain atrophy； 10 patients （67%） had abnormal signals in the bilateral or unilateral hippocampus，and 3 patients （20%） had abnormal signals in the cortex/subcortical regions. All 15 patients received first-line immunotherapy，and dynamic MRI follow-up was performed for 8 patients，with a follow-up time of half a year to 4 years. Follow-up results showed that based on clinical and imaging findings，the patients with abnormal signals in the cortex/subcortical regions had good response to immunotherapy，while those with abnormal signals in the bilateral or unilateral hippocampus had poor response to immunotherapy. Progressive brain atrophy was observed in all 8 patients receiving MRI follow-up.Conclusion The common imaging findings of anti-GAD65 antibody-associated autoimmune neurological syndromes include abnormal signals in the bilateral or unilateral hippocampus and abnormal signals in the cortex/subcortical regions，and there are differences in clinical manifestations and response to immunotherapy between these two types. Cranial MRI features have an important value in the diagnosis of anti-GAD65 antibody-associated syndromes. MRI examination may be used as an important method for monitoring disease progression and treatment outcome.

OBJECTIVE: To develop a digital intelligent multimodal shift handover system for the intensive care unit (ICU) and evaluate its application effect in ICU shift handovers. METHODS: A research and development team was established, consisting of 1 department director, 1 head nurse, 3 information technology engineers, 3 nurses, and 2 doctors. Team members were assigned responsibilities including overall coordination and planning, platform design and maintenance, pre-application training, collection and organization of clinical feedback, and research investigation respectively. A digital intelligent multimodal shift handover system was developed for ICU based on the Shannon-Weaver linear transmission model. This innovative system integrated automated data collection, intelligent dynamic monitoring, multidimensional condition analysis and visual reporting functions. A cloud platform was used to gather data from multi-parameter vital signs monitors, infusion pumps, ventilators and other devices. Artificial intelligence algorithms were employed to standardize and analyze the data, providing personalized recommendations for healthcare professionals. A self-controlled before-after method was adopted. Before the application of the ICU digital intelligent multimodal shift handover system (from December 2023 to March 2024), the traditional verbal bedside handover was used; from June 2024 to March 2025, the ICU digital intelligent multimodal shift handover system was applied for shift handovers. Questionnaires before the application of the shift handover system were collected in April 2024, and those after the application were collected in April 2025. The shift handover time, handover quality (scored by the nursing handover evaluation scale), satisfaction with doctor-nurse communication (scored by the ICU doctor-nurse scale) before and after the application of the handover system were compared, and nurses' satisfaction with the shift handover system (scored by the clinical nursing information system effectiveness evaluation scale) was investigated. RESULTS: After the application of the ICU digital intelligent multimodal shift handover system, the shift handover time was significantly shorter than that before the application [minutes: 20 (15, 25) vs. 30 (22, 40)], the handover quality was significantly higher than that before the application [score: 84.0 (78.0, 88.5) vs. 71.0 (55.0, 79.0)], and the satisfaction with doctor-nurse communication was also significantly higher than that before the application (score: 84.58±6.79 vs. 74.50±11.30). All differences were statistically significant (all P < 0.05). In addition, the nurses' system effectiveness evaluation scale score was 102.30±10.56, which indicated that nurses had a very high level of satisfaction with the ICU digital intelligent multimodal shift handover system. CONCLUSIONS The application of the ICU digital intelligent multimodal shift handover system can shorten the shift handover time, improve the handover quality, and enhance the satisfaction with doctor-nurse communication. Nurses have a high level of satisfaction with this system.

Objective:To analyze the monitoring results of human brucellosis prevention and control project in Gansu Province, in order to provide reference for the next revision of prevention and control plans.Methods:The data from the "China Disease Prevention and Control Information System" in Gansu Province from 2016 to 2022 and the annual data of human brucellosis cases reported by the active monitoring reports in various project counties (districts) were input into Excel 2016 software and a database was established. The epidemiological situation of brucellosis, the coverage of brucellosis prevention and control projects, the number of detected cases and health education were analyzed and compared by descriptive epidemiological method.Results:From 2016 to 2022, 70 to 82 out of 86 counties (districts) in Gansu Province were found to have human outbreaks of brucellosis, with brucellosis prevention and control projects covering 17 to 43 counties (districts). A total of 19 855 cases of human brucellosis were reported online in the province, with an average annual incidence of 11.07/100 000 and an annual incidence ranging from 6.03/100 000 to 20.89/100 000. There was a statistically significant difference in incidence among years (χ 2 = 5 264.84, P < 0.001). Through active monitoring, a total of 433 303 cases of brucellosis (tiger red plate agglutination test, RBT) were initially screened in project counties (districts) throughout the province, with 13 277 positive cases and a positive rate of 3.06% (13 277/433 303). Then the laboratory confirmed test (test-tube agglutination test, SAT) for brucellosis was carried out, with 9 967 positive cases and a positive rate of 2.30% (9 967/433 303). The infection rate of brucellosis in the population (SAT positive) was compared between different years, and the difference was statistically significant (χ 2 = 600.12, P < 0.001). In the project counties (districts), 7 481 confirmed cases of brucellosis were detected by active surveillance, and 15 794 cases were reported online, accounting for 47.37% (7 481/15 794) of the total number of cases reported online. The average awareness rate of brucellosis knowledge among medical personnel increased from 70.49% before training to 88.89% after training. The average awareness rate of brucellosis prevention and control knowledge among high-risk groups increased from 63.49% before health education to 89.05% after health education, and the behavior formation rate increased from 62.84% to 86.04%. Conclusions:From 2016 to 2022, the epidemic scope of human brucellosis in Gansu Province has been expanding year by year, and the coverage of prevention and control project is relatively small. The proportion of cases detected through active screening is relatively low. It is necessary to increase special funding investment, expand project coverage, strengthen high-risk group screening, education and behavioral intervention, and follow-up management of acute stage patient, so as to identify patients as early as possible and curb the upward trend of the epidemic.

Objective To investigate the clinical value of high resolution vascular wall imaging(HRVWI)in the diagnosis and treatment of central nervous system vasculitis(CNSV)in children.Methods A total of 36 children with CNSV underwent HRVWI examination were selected.The HRVWI imaging features,involved vessel types and stenosis degree were analyzed retrospectively and compared with magnetic resonance angiography(MRA).Combined with some patients'follow-up and reviewed imaging after treatment.Results HRVWI showed that all of the 36 children with CNSV had cerebral arteritis,and the affected inflammatory ves-sels showed varying degrees of focal arterial wall thickening and enhancement,mainly uniform thickening and centripetal enhance-ment of the affected arterial wall.Most were mid-enhanced,and the stenosis degree was mostly at level 1(21/36).According to the type of involvement cerebrovascular,there were 26 cases of large-medium vessel type,6 cases of small vessel type and 4 cases of mixed type.Compared with MRA,HRVWI had a higher sensitivity in diagnosing CNSV(P＜0.05).13 cases were followed up after treat-ment,and HRVWI showed cerebral vasculitis relief in 8 cases and progression in 5 cases,consistent with changes in clinical symp-toms and laboratory indicators.Conclusion The imaging features of CNSV in children with different causes are different.HRVWI has a high sensitivity in the diagnosis of CNSV in children.HRVWI plays an important role in the diagnosis and treatment of CNSV in children.

Objective:To explore the effects of home hospice care team service model in patients with end-stage malignant tumors and main caregivers, so as to provide intervention programs for improving the quality of life of patients with end-stage malignant tumors.Methods:In the prospective and controlled study, 106 patients with malignant tumors who received end-stage hospice care in Yuebei People′s Hospital and main caregivers from May 2021 to July 2021 were selected by convenience sampling method, and divided into trial group (53 pairs) and control group (53 pairs) according to the random number table method. The control group was treated with routine nursing intervention, and the trial group was given home hospice care team service model intervention based on the control group. The occurrence of falls and negative emotions and quality of life of patients, psychological stress of primary caregivers before and after intervention were observed by using Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Relative Stress Scale (RSS) and European Organization for Research and Treatment of Cancer Quality of Life Scale (EORTC QLQ-C30).Results:Finally, 103 patients and main caregivers completed the study, with 52 pairs in the control group and 51 pairs in the trial group. In the control group, the patients were 29 males and 23 females, aged (54.33 ± 12.24) years old,and the main caregivers were 22 males and 30 females, aged (41.67 ± 8.14) years old. In the trial group,the patients were 27 males and 24 females,aged (55.17 ± 10.56) years old,and the main caregivers were 24 males and 27 females, aged (43.62 ± 7.39) years old. After intervention, the total incidence of falls and the total incidence of fall complications in the trial group were 7.84% (4/51) and 1.96% (1/51), respectively, which were lower than 25.00% (13/52) and 11.54% (7/52) in the control group, the differences were statistically significant ( χ2=5.50, 4.75, both P<0.05). There was no significant difference in the score of SAS, SDS, RSS, EORTC QLQ-C30 before intervention between the two groups (all P>0.05). After intervention, the scores of SAS and SDS in trial group were (32.66 ± 3.18), (31.19 ± 4.50) points,which lower than those in control group (34.54 ± 3.91), (34.31 ± 4.03) points, the differences were statistically significant ( t=2.67, 2.51, both P<0.05). After intervention, the RSS scores of psychological distress, life disruption, negative emotion and total score of the main caregivers in trial group were (3.52 ± 0.48), (3.66 ±0.56), (3.47 ± 0.82), (10.65 ± 0.67) points, which were lower than those in the control group (4.74 ± 2.75), (4.67 ± 2.64), (4.12 ± 2.13), (13.53 ± 2.26) points, the differences were statistically significant ( t values were 2.04-8.73, all P<0.05). After intervention, the EORTC QLQ-C30 score in the trial group was (74.14 ± 5.64) points, which was lower than that in the control group (70.54 ± 7.07) points, the difference was statistically significant ( t=2.85, P<0.05). Conclusions:The application of home hospice care team service model can effectively reduce the risk of falls in patients with malignant tumor chemotherapy, improve the negative emotions of patients and the psychological stress state of their main caregivers, and improve the quality of life of patients.

Background::Genetic variants of dopaminergic transcription factor-encoding genes are suggested to be Parkinson’s disease (PD) risk factors; however, no comprehensive analyses of these genes in patients with PD have been undertaken. Therefore, we aimed to genetically analyze 16 dopaminergic transcription factor genes in Chinese patients with PD.Methods::Whole-exome sequencing (WES) was performed using a Chinese cohort comprising 1917 unrelated patients with familial or sporadic early-onset PD and 1652 controls. Additionally, whole-genome sequencing (WGS) was performed using another Chinese cohort comprising 1962 unrelated patients with sporadic late-onset PD and 1279 controls.Results::We detected 308 rare and 208 rare protein-altering variants in the WES and WGS cohorts, respectively. Gene-based association analyses of rare variants suggested that MSX1 is enriched in sporadic late-onset PD. However, the significance did not pass the Bonferroni correction. Meanwhile, 72 and 1730 common variants were found in the WES and WGS cohorts, respectively. Unfortunately, single-variant logistic association analyses did not identify significant associations between common variants and PD. Conclusions::Variants of 16 typical dopaminergic transcription factors might not be major genetic risk factors for PD in Chinese patients. However, we highlight the complexity of PD and the need for extensive research elucidating its etiology.

Background::Gastric cancer (GC), a malignant tumor with poor prognosis, is one of the leading causes of cancer-related deaths worldwide; consequently, identifying novel therapeutic targets is crucial for its corresponding treatment. NUF2, a component of the NDC80 kinetochore complex, promotes cancer progression in multiple malignancies. Therefore, this study aimed to explore the potential of NUF2 as a therapeutic target to inhibit GC progression. Methods::Clinical samples were obtained from patients who underwent radical resection of GC at Lanzhou University Second Hospital from 2016 to 2021. Cell count assays, colony formation assays, and cell-derived xenotransplantation (CDX) models were used to determine the effects of NUF2 on GC progression. Flow cytometry was used to detect the effect of NUF2 or quercetin on cell cycle progression and apoptosis. A live-cell time-lapse imaging assay was performed to determine the effect of NUF2 on the regulation of mitotic progression. Transcriptomics was used to investigate the NUF2-associated molecular mechanisms. Virtual docking and microscale thermophoresis were used to identify NUF2 inhibitors. Finally, CDX, organoid, and patient-derived xenograft (PDX) models were used to examine the efficacy of the NUF2 inhibitor in GC. Results::NUF2 expression was significantly increased in GC and was negatively correlated with prognosis. The deletion of NUF2 suppressed GC progression both in vivo and in vitro. NUF2 significantly regulated the mitogen-activated protein kinase (MAPK) pathway, promoted G2/M phase transition, and inhibited apoptosis in GC cells. Additionally, quercetin was identified as a selective NUF2 inhibitor with low toxicity that significantly suppressed tumor growth in GC cells, organoids, CDX, and PDX models. Conclusions::Collectively, NUF2-mediated G2/M phase transition and apoptosis inhibition promoted GC progression; additionally, NUF2 inhibitors exhibited potent anti-GC activity. This study provides a new strategy for targeting NUF2 to suppress GC progression in clinical settings.

Objective:To investigate the protective effects and mechanism of Shenyan 1 Prescription on renal fibrosis of unilateral ureteral obstruction (UUO) rats through TGF- β 1/Smad homologous 3 (Smad3) pathway regulating ferroptosis.Methods:Totally 48 male SD rats were divided into four groups: sham-operation group, UUO model group, and Shenyan 1 Prescription low-(10 drug/kg) , and high-dosage (20 crude drug/kg) groups according to random number table method, with 12 rats in each group. The UUO model was induced by the method of unilateral ureteral obstruction except for those sham-operation group. After modeling, rats received corresponding drugs or normal saline by gavage for 4 weeks, once per day. After 4 weeks, the body mass and the left kidney weight were measured. The 24 h urine protein and the levels of serum albumin (ALB), alanine aminotransferase (ALT), serum creatinine (SCr) and blood urea nitrogen (BUN) were detected by biochemical analysis method; the ROS level in renal tissue was measured using a chemical fluorescence assay kit, and the SOD and MDA levels in left renal tissue of rats were measured using ELISA method; the morphology of renal tissue and the specific blue staining of hemosiderin were observed using HE and Prussian blue staining methods, respectively; the expressions of transforming growth factor-β1 (TGF-β1), Smad3, glutathione peroxidase 4 (GPX4), and solute carrier family 1 member 5 (SLC1A5) were detected by Western blot.Results:Compared with the model group, the 24 h urinary protein excretion in Shenyan 1 Prescription high-dosage group decreased ( P<0.05), the serum ALB level increased ( P<0.05), the ALT level decreased ( P<0.05), and the expression of SLC1A5 in renal tissue decreased ( P<0.05); the left kidney weight/body decreased in Shenyan 1 Prescription low- and high-dosage groups ( P<0.05); the levels of serum ROS and MDA decreased ( P<0.05), and the activity of SOD significantly increased ( P<0.05); the expressions of TGF-β1 and Smad3 in renal tissue decreased ( P<0.05), and the expression of GPX4 increased ( P<0.05), and the renal pathological injury and ion deposition were improved. Conclusion:Shenyan 1 Prescription has a protective effect on the structure and function of renal tissues in UUO rats through regulating ferroptosis via inhibition of the TGF-β1/ Smad3 pathway to inhibit renal fibrosis of UUO rats.
