Objective:To examine the impact of Developmental Human Resource Management Practices(D-HRMPs)on innova-tive performance of health professionals from the public hospitals.Methods:A questionnaire survey was conducted to collect data from health professionals in the public hospitals in Beijing,including D-HRMPs scale,innovation performance scale,inclusive lead-ership scale and team innovation atmosphere scale.Descriptive statistics and structural equation model were used for the analysis.Results:D-HRMPs had a direct effect on the innovation performance of public hospital health professionals.Inclusive leadership can positive-ly affect the implementation of D-HRMPs and the formation of team innovation atmosphere.Meanwhile,team innovation atmo-sphere plays a mediating effect,that is,D-HRMPs can actively promote the formation of team innovation climate,and further indi-rectly affect the innovation performance of employees.Conclusion:The directors of public hospitals can further explore the im-plementation of D-HRMPs,and pay attention to adopting inclusive leadership to deepen the reform of personnel management system,and promote high-quality development of public hospitals.

AIM: To assess the clinical efficacy of visual therapy in children with abnormal visual functions and asthenopia.METHODS: Retrospective case study. The data of 57 patients(114 eyes), aged 8.25±1.94 years, who underwent visual training at the optometry center of Xi'an Children's Hospital between January 2022 and April 2023, were collected. Patient assessments before and after training included refractive errors, a visual fatigue scale questionnaire, and visual function tests. These tests included the Worth 4 Dot for binocular vision, the Von Graefe method for measuring latent strabismus at distance and near, the gradient method for assessing the accommodative convergence/accommodation(AC/A)ratio, the push-up test for convergence near point, the negative lens method for amplitude of accommodation, the cross-cylinder test for accommodative response, and the flipper test for accommodative flexibility. Training programs were tailored based on the initial assessments of visual function and asthenopia. Comparisons were made between pre-training, 1 and 3 mo post-training evaluations.RESULTS: At baseline and 1 mo post-training, the visual fatigue scores were 26.00±6.77 and 19.57±8.90, respectively(P<0.05). Significant enhancements were observed in near phoria, convergence near point, and accommodative amplitude in both eyes, both negative relative accommodation(NRA)and positive relative accommodation(PRA), as well as accommodative flexibility in both eyes at 1 mo after therapy(all P<0.05), while no significant changes were found in distance phoria or accommodative response(all P>0.05). Furthermore, no significant differences were noted in the binocular amplitude of accommodation, NRA, PRA, and near phoria between 1 and 3 mo after training(all P>0.05). The visual function parameters of 30 patients with low myopia(SE: -1.99±1.22 D), 3 patients with low hyperopia(SE: +1.01±0.13 D)and 24 patients with emmetropia(SE: +0.25±0.11 D)were not statistically significant before training and at 1 mo after training(all P>0.05). Certain visual functions significantly improved at 1 mo after training, and most had returned normal by 3 mo.CONCLUSION: Vision therapy significantly enhances binocular visual function and alleviates symptoms of asthenopia in children with visual dysfunction. It is an effective, straightforward, and easily applicable method for relieving children's visual fatigue.

OBJECTIVE To screen the potential active components of Polygonum orientale flower against myocardial ischemia- reperfusion injury （MIRI） in rats based on physiological and pathological states. METHODS SD rats were divided into normal control group， normal administration group， MIRI control group and MIRI administration group， with 5 rats in each group. After drug intervention or modeling and drug intervention， chromatographic separation plasma samples were collected， and chromatographic separation and mass spectrometry data collection were performed by using UPLC-Q-TOF/MS. The prototype components and metabolites were analyzed by comparing the reference substance maps， the maps of each plasma sample， and the relevant literature. At the same time， the common peaks in plasma samples of rats in normal administration group and MIRI administration group were identified. Combined with principal component analysis and orthogonal partial least square-discriminant analysis， the differential transitional components were screened out according to the value of variable importance in the projection （VIP）＞1， to speculate the potential active components of P. orientale flower in rats under physiological and pathological states. The SD rats were divided into control group， MIRI group， positive control group （Compound danshen tablets 0.2 g/kg， 3 times a day）， and potentially active compound groups （10 mg/kg， twice a day）， with 5 rats in each group. The rats in administration groups were given relevant medicine intragastrically， for 3 consecutive days. The activity of superoxide dismutase （SOD）， the leakages of lactate dehydrogenase （LDH）， creatine kinase isoenzyme-MB （CK-MB） and cardiac troponin Ⅰ （cTnⅠ） in plasma were detected after the last administration. RESULTS Twenty-six main chromatographic peaks were obtained from the total ion chromatogram of the extract of P. orientale flower， and 14 of them were determined， including gallic acid， catechin， protocatechuic acid and so on. There were fifteen （including 6 absorbed prototype components and 9 metabolites） and nineteen transitional components （including 6 absorbed prototype components and 13 metabolites） in the plasma sample of normal rats and MIRI rats. Eight transitional components were detected in both normal rats and MIRI rats， and the VIP values of kaempferol glucuronidation metabolites， quercetin carbonylation metabolites and N-p-paprazine to the corresponding peak were higher than 1. Compared with MIRI group， the activities of SOD were increased significantly in the plasma of MIRI rats in each potential active compound group （P＜0.01）， and the leakages of LDH， CK-MB， and cTnⅠ in the plasma of MIRI rats were reduced significantly （P＜0.01）. CONCLUSIONS The potential anti-MIRI active components in extract of P. orientale flower are N-p-paprazine， quercetin， kaempferol and kaempferol-3-O-β-D-glucoside.

OBJECTIVE To investigate the effects and mechanism of galangin （GAL） on hepatocyte apoptosis in rats with obstructive jaundice （OJ） based on the Janus kinase 2 （JAK2）/signal transduction and activator of transcription 3 （STAT3） signaling pathway. METHODS Taking male SD rats as the object， the OJ model was established by double ligation of common bile duct， and 48 rats with successful modeling were randomly separated into OJ model group （model group）， low-dose GAL group （GAL-L group）， high-dose GAL group （GAL-H group） and high-dose GAL+JAK2 activator colivelin group （GAL-H+ colivelin group）， with 12 rats in each group； another 12 SD rats with laparotomy/abdominal closure without ligation were selected as sham operation group （sham group）. Each administration group was given relevant medicine intragastrically and/or intraperitoneally， once a day， for 7 consecutive days. After the last medication， the morphology of liver tissue in rats was observed； the serum levels of total bilirubin （TBIL）， direct bilirubin （DBIL）， alanine transaminase （ALT） and γ -glutamyltransferase （GGT）， as well as the levels of superoxide dismutase （SOD） and malondialdehyde （MDA） in mail：guoweishengjcy@126.com liver tissue were detected. The apoptotic rate of liver tissue cells， the expression levels of signaling pathway-related proteins （phosphorylated JAK2， JAK2， phosphorylated STAT3， STAT3） and apoptosis-related proteins [B cell lymphoma 2 （Bcl-2）， Bcl-2 related X protein （Bax）] were determined. RESULTS Compared with sham group， congestion of liver sinusoids， damage to liver lobules， disordered arrangement and swollen morphology of liver cells， the disappearance of nucleoli， and significant infiltration of inflammatory cells and fibrous tissue proliferation were observed in model group； the serum levels of TBIL， DBIL， ALT and GGT， the level of MDA in liver tissue， the apoptosis rate of liver cells， the protein expression of Bax， and the protein phosphorylation levels of JAK2 and STAT3 in liver tissue of model group were increased significantly （P＜0.05）； the level of SOD and the protein expression of Bcl-2 in liver tissue were decreased significantly （P＜0.05）. Compared with the model group， the pathological injuries of liver tissue were relieved in GAL-L group and GAL-H group， all quantitative indicators had significantly improved， and the effect of GAL-H group was more significant （P＜ 0.05）. Colivelin could significantly reverse the improvement effects of GAL on liver injury and related indicators of OJ rats （P＜ 0.05）. CONCLUSIONS GAL may inhibit liver cell apoptosis in OJ rats， improve liver function and alleviate oxidant stress， the mechanism of which may be associated with inhibiting JAK2/STAT3 signaling pathway.

Objective: To identify the stakeholders of prevention and control of obesity among middle school students and analyze their motivations and interest demands for participation, in order to provide constructive recommendations for facilitating their effective engagement of stakeholders in prevention and control of obesity among middle school students. Methods: Stakeholders and their types were identified through a combination of literature analysis and consultation with 17 experts in children and adolescents for prevention and control of obesity. From December 2023 to January 2024, by applying convenience sampling, face to face semi structured interviews were conducted with 11 individuals engaged in prevention and control of obesity for middle school students and focus group interviews were conducted with 48 students and parents. Thematic analysis was employed to obtain motivations and interest demands for stakeholder involvement in prevention and control of obesity. Results: A total of 29 subcategories within 7 major categories of stakeholders were identified, including government and relevant functional departments, non profit organizations and communities, forprofit organizations and individuals, schools, professional and technical personnel, families and individuals, and scientific research institutions, with 28 subcategories being confirmed stakeholders. Among these stakeholders, there were 3 types of cooperative relationships:management, cooperation, and service. There were some factors hindering cooperation among stakeholders including imperfections in specialized policies and lack of long term cooperative mechanisms, flaws and interest conflicts in the evaluation system, insufficiency of material resources, and poor health values. In response to these challenges, interviewees proposed to convene a working group for the prevention and control of adolescent obesity. They also suggested making a contract of responsibility, strengthening supervision over for profit organizations, enhancing advocating efforts for prevention and control of obesity, and increasing financial support. Conclusions The prevention and control of obesity for middle school students can be facilitated by forming a collaborative alliance based on the roles and relationships of stakeholders identified in the present study. Perceived conflicts of interest among stakeholders can be reconciled by employing strategies of interest integration, goal alignment, and spiritual integration, to enhance the feasibility, participation and sustainability of obesity intervention.

Objective:To analyze the prognosis,clinicopathological characteristics,and genetic mutation features of patients with very low-and low-risk gastrointestinal stromal tumors(GISTs).Methods:A retrospective data collection of 433 patients with very low-and low-risk GISTs,diagnosed by pathology after surgical or endoscopic resection at Tianjin Medical University Cancer Institute&Hospital,was conduc-ted to analyze clinical pathology and prognosis.Results:Compared with low-risk GIST,a higher proportion of patients with very low-risk GIST had gastric GISTs,a Ki-67 index≤3%,and 0-1 mitotic indexes/5 mm2,whereas the proportion of patients with small intestinal GIST was low(all P<0.05).Genetic testing was performed in 118 patients,and there was no significant difference in the mutation types and KITmutation types between low-risk and very low-risk GISTs(all P>0.05).Patient follow-up was conducted on 87 very low-risk and 210 low-risk GIST pa-tients without other concurrent diseases,with a median follow-up of 86(27-158)months.None of the patients with very low-risk GISTs showed progression;three cases of low-risk GIST had recurrence or metastasis,with progression-free survival(PFS)ranging from 27 to 84 months.The mitotic indices of the primary tumors in these three patients were all 4/5 mm2,which is close to the critical value between the low-and intermediate-risk GIST mitotic indices,and all had KIT exon11 mutations.After the first progression,these three patients were treated with imatinib,and all survived until the end of follow-up,with overall survival ranging from 116 to 155 months.Conclusions:Among patients with low-risk GISTs,a very small number with high mitotic indices may have the potential for recurrence or metastasis,but after re-currence or metastasis,they can still maintain long-term,high-quality survival through targeted therapy,surgery,and other treatment meth-ods.The possibility of postoperative progression in very low-risk patients with GIST is extremely low,and the follow-up interval can be ap-propriately extended to reduce medical costs and alleviate the psychological burden on the patients and their families.

Objective To compare the efficacy and difference of transvaginal natural orifice transluminal endoscopic surgery(v-NOTES),transumbilical laparoendoscopic single site surgery(TU-LESS)and traditional laparoscopic surgery in the treatment of ectopic pregnancy.Methods A total of 121 patients with ectopic pregnancy admitted to Yangzhou Maternal and Child Care Service Centre,Affiliated to Yangzhou University Medical School from June 2019 to June 2022 were retrospectively selected.According to different surgical methods,the included patients were divided into traditional laparoscopic group(49 cases),TU-LESS group(43 cases)and v-NOTES group(29 cases).Age,body mass index(BMI),hemoglobin(Hb),operation time,intraoperative bleeding,postoperative exhaust time,and 24h postoperative visual analogue scale(VAS)score,postoperative hospital stay and satisfaction of patients in each group were observed.Results The exhaust time and postoperative hospital stay in v-NOTES group were significantly shorter than those in traditional laparoscopic group and TU-LESS group,and 24h postoperative VAS score was significantly lower than that in traditional laparoscopic group and TU-LESS group(P<0.05).There was significant difference in postoperative satisfaction among three groups(H=57.364,P<0.001),and v-NOTES group>TU-LESS group>traditional laparoscopic group.Conclusion Compared with TU-LESS and traditional laparoscopic surgery,v-NOTES treatment of ectopic pregnancy recovery faster,less pain,more beautiful appearance,but need to be mastered by the operator.

Purpose: Patients with advanced biliary tract cancer (BTC) have a poor survival. We aim to evaluate the efficacy and safety of nab-paclitaxel plus gemcitabine and cisplatin regimen in Chinese advanced BTC patients. Materials and Methods: Eligible patients with locally advanced or metastatic BTC administrated intravenous 100 mg/m2 nab-paclitaxel, 800 mg/m2 gemcitabine, and 25 mg/m2 cisplatin every 3 weeks. The primary endpoint was progression-free survival (PFS). The secondary endpoints included overall survival (OS) and adverse events, while exploratory endpoint was the association of biomarkers with efficacy. Results: After the median follow-up of 25.0 months, the median PFS and OS of 34 enrolled patients were 7.1 months (95% confidence interval [CI], 5.4 to 13.7) and 16.4 months (95% CI, 10.9 to 23.6), respectively. The most common treatment-related adverse events at ≥ 3 grade were neutropenia (26.5%) and leukopenia (26.5%). Survival analyses demonstrated that carcinoembryonic antigen (CEA) levels could monitor patients’ survival outcomes. A significant increase in the number of infiltrating CD4+ cells (p=0.008) and a decrease in programmed death-1–positive (PD-1+) cells (p=0.032) were observed in the response patients. Conclusion In advanced BTC patients, nab-paclitaxel plus gemcitabine and cisplatin regimen showed therapeutic potential. Potential prognostic factors of CEA levels, number of CD4+ cells and PD-1+ cells may help us maximize the efficacy benefit.

Fibroblast growth factors (FGF) are a group of structurally related polypeptides which constitute an elaborate signaling system with their receptors. Evidence accumulated in the years suggests that the FGF family plays a key role in the repair of central nervous system injury. The main protective mechanisms include activating the expression of PI3K-Akt, peroxisome proliferator-activated receptor (PPARγ) and other signals; inhibiting NF-κB-mediated inflammatory response, oxidative stress and apoptosis; regulating neuronal differentiation and neuronal excitability as well as participating in protection of neurovascular units and nerve function repair. This paper comprehensively summarizes the latest research progress in FGF signaling related to diseases of the central nervous system such as cerebral infarction, cerebral hemorrhage, traumatic brain injury, Alzheimer's disease, Parkinson's disease, epilepsy and depression, aiming to provide scientific basis and reference for the development of innovative FGF drugs for the prevention and treatment of neurological diseases.

Objective:To explore the β-amyloid (Aβ) deposition pattern of subjects with the preclinical Alzheimer′s disease (AD), community-derived amnestic mild cognitive impairment (aMCI) and normal cognition (NC) from communities of Shanghai.Methods:According to the inclusion and exclusion criteria, 273 subjects (104 males, 169 females; age (64.2±7.6) years) were recruited from Shanghai community and memory clinics from December 2018 to July 2020. All subjects underwent MRI, 18F-AV45 PET imaging and neuropsychological scale tests and were grouped into AD, aMCI and NC groups based on clinical diagnosis. Differences in demographic information, the neuropsychological scale tests′ scores and positive rate of Aβ deposition among each group were analyzed by one-way analysis of variance or χ2 test. Aβ deposition patterns of AD and MCI groups were analyzed at voxel level, and the differences of Aβ deposition among different groups were compared. Results:Among 273 patients, the positive rates of Aβ deposition in AD, aMCI and NC groups were 84.4%(38/45), 36.4%(20/55) and 23.1%(40/173), respectively ( χ2=58.37, P<0.001). Among AD, aMCI, NC and NC (Aβ-) groups ( n=132), the education years of AD group was the lowest ((9.7±4.6) years; F=8.86, P<0.001). In addition, there were significant differences in the scores of several neuropsychological scale tests among AD, aMCI, NC groups and NC (Aβ-) group ( F values: 27.68-235.50, all P<0.001). Compared with subjects in NC(Aβ-) group, the Aβ depositions in the aMCI and AD groups were widely distributed in the whole cerebral cortex; and AD group had higher Aβ deposition in bilateral frontal, parietal, temporal, occipital lobe, cingulate gyrus and precuneus than aMCI group. Conclusions:The positive rate of Aβ deposition in the preclinical AD population from the Shanghai community is obtained. There are significant different Aβ deposition patterns in subjects at different stages of AD.
