Health communication aims to improve public health attitudes and behaviors by propagating health information. It plays an important role in promoting public health literacy and "Healthy China Initiative". The basic theories of health communication include "7 W" and Theory of Planned Behavior. Clinicians with profound medical expertise and a wealth of clinical practice play key roles in the communication, and they hold an unparalleled advantage in health communication by delivering authoritative and trustworthy information to the public. The capacity of health communication among clinicians in the nation is determined by various factors including professional characteristics, policy support, dissemination platforms and pathways, time and effort. Meanwhile, some problems in the research on the health communication capacity of clinicians remain, such as lack of well-established motivation systems, limited dissemination pathways, and imperfect evaluation frameworks. In some regions of China, health communication performance has been considered as part of the professional title evaluation for clinical physicians. Medical institutions and universities have also initiated relevant training and practice programs. It is crucial to improve evaluation frameworks, strengthen training pathways and effectiveness assessment, promote interdisciplinary integration, and enhance the role of clinicians in health communication in the future.

ObjectiveTo investigate the mechanism by which Mingshi prescription regulates the retinal melanopsin-dopamine （Opn4-DA） axis in myopic mice to inhibit endoplasmic reticulum （ER） stress in the retina and sclera， thereby delaying axial elongation associated with myopia. MethodsSixty 4-week-old male SPF-grade C57BL/6J mice were randomly divided into a normal group， a form-deprived myopia group （FDM group）， an intrinsically photosensitive retinal ganglion cells ablation group （ipRGCs group）， a Mingshi Prescription group （MSF group， 5.2 g·kg^-1）， and an ipRGCs + MSF group （5.2 g·kg^-1）. Except for the normal group， all other groups underwent FDM modeling. Additionally， the ipRGCs and ipRGCs + MSF groups received retinal ipRGC ablation. Three weeks after modeling， the MSF and ipRGCs + MSF groups were administered Mingshi prescription via continuous gavage for six weeks. After refraction and axial length were measured in all mice， eyeballs were collected along with retinal and scleral tissues. Pathological and morphological changes in the retina， choroid， and sclera were observed using periodic acid-Schiff （PAS） staining. Western blot was employed to detect the relative protein expression levels of dopamine D1 receptor （DRD1）， C/EBP homologous protein （CHOP）， and glucose-regulated protein 78 （GRP78） in the retina， and CHOP and GRP78 in the sclera. Real-time PCR was used to detect the relative mRNA expression of Opn4， CHOP， and GRP78 in the retina， and CHOP and GRP78 in the sclera. Immunofluorescence staining （IF） was performed to detect the expression of Opn4 and DRD1 in retinal tissues. ResultsCompared with the normal group， the FDM group showed a significant myopic shift in refraction （P<0.05） and a significant increase in axial length （P<0.05）. The retinal layers were thinner， the number of ganglion cells was reduced， and collagen fibers in the sclera were loosely arranged with evident gaps. Opn4 and DRD1 protein and mRNA expression in the retina were significantly decreased （P<0.05）， while CHOP and GRP78 protein and mRNA expression in both retinal and scleral tissues were significantly increased （P<0.05）. Compared with the FDM group， the ipRGCs group exhibited further increases in myopic refraction and axial length （P<0.05）， more pronounced thinning and looseness in the retinal， choroidal， and scleral layers， lower expression of Opn4 and DRD1 protein and mRNA in the retina （P<0.05）， and higher expression of CHOP and GRP78 protein and mRNA in the retina and sclera （P<0.05）. Compared with the FDM group， the MSF group showed significantly reduced refractive error and axial length （P<0.05）， with improved cellular number， arrangement， and thickness in ocular tissues， increased Opn4 and DRD1 protein and mRNA expression in the retina （P<0.05）， and reduced CHOP and GRP78 protein and mRNA expression in both retina and sclera （P<0.05）. Similarly， the ipRGCs + MSF group showed significant improvements in terms of the above items compared with the ipRGCs group （P<0.05）. ConclusionMingshi Prescription delays myopic axial elongation and refractive progression by regulating the Opn4-DA axis in the retina of myopic mice， thereby inhibiting ER stress in the retina and sclera. This intervention promotes Qi and blood nourishment of the eyes， softens the fascia， and restores ocular rhythm.

ObjectiveTo investigate the effects of Chaihu and Longgu Mulitang （CLMT） on hippocampal neural damage in the mouse model of depression via the extracellular signal-regulated protein kinase （ERK）/cAMP-response element-binding protein （CREB） signaling pathway. MethodsSeventy-eight male C57BL/6 mice were randomly allocated into normal control， model， low/medium/high-dose （2.89， 5.78， and 11.56 g·kg^-1， respectively） CLMT， and paroxetine （10 mg·kg^-1） groups. A depression model was established by chronic unpredictable mild stress （CUMS） combined with social isolation. Behavioral tests were carried out to evaluate depressive-like behaviors. Hematoxylin-eosin staining and Nissl staining were performed to assess hippocampal morphology and neuronal damage. Immunofluorescence was employed to detect glial fibrillary acidic protein （GFAP） and ionized calcium-binding adapter molecule 1 （Iba1）. Real-time PCR was employed to measure the mRNA levels of ERK and CREB. Western blot was employed to determine the expression of ERK/CREB pathway proteins and brain-derived neurotrophic factor （BDNF） in the hippocampal tissue. Molecular Operating Environment （MOE） software was used for molecular docking to evaluate the interactions between CLMT components and target proteins. ResultsCompared with the normal control group， the model group showed decreased sucrose preference （P0.01）， increased tail-suspension immobility time （P0.01）， decreased activity in the central region of the open field test （P0.01）， and decreased activity in the middle and open-arm region of the elevated plus maze test （P0.01）. The hippocampal area in the model group showed wrinkled cells and a reduction in the number of cells， neurons with reduced sizes and Nissl bodies， enhanced fluorescence intensity of GFAP and Iba1 （P0.01）， and down-regulated expression of phosphorylated （p）-ERK， p-CREB， and BDNF （P0.05， P0.01） and mRNA levels of ERK and CREB （P0.01）. Compared with the model group， the CLMT group showed increased body weight （P0.05， P0.01）， restored cell morphology， with only a small number of ruptured cells， normal neuronal structure and morphology with obvious nuclei and abundant Nissl bodies， weakened fluorescence intensity of GFAP and Iba1 （P0.05， P0.01）， up-regulated mRNA levels of ERK and CREB （P0.05， P0.01） and protein levels of phosphorylated （p）-ERK， p-CREB， and BDNF in the hippocampal tissue （P0.05， P0.01）. The results of molecular docking indicated that nine active ingredients in CLMT had good binding affinity with ERK and CREB. ConclusionCLMT may ameliorate the hippocampal nerve injury in the mouse model of depression by regulating the ERK/CREB pathway.

Objective:To explore the current status of rumination in inpatients with metastatic prostate cancer (mPCa) under the disease coping mechanism, and analyzing its influencing factors.Methods:From March 2021 to December 2022, 267 mPCa inpatients at the Tenth People's Hospital of Tongji University were selected as the study subject using convenience sampling. The survey was conducted using the General Information Questionnaire, Chinese Version of Event Relate Rumination Inventory (C-ERI), Medical Coping Modes Questionnaire (MCMQ), International Prostate Symptom Score (IPSS), and Social Support Revalued Scale (SSRS), and the factors influencing the rumination in patients were analyzed.Results:This study collected 260 valid questionnaires, with an effective response rate of 97.4% (260/267). The total score of rumination in 260 mPCa patients was (31.08±6.46), with invasive rumination and purposeful rumination scores of (14.13±4.44) and (16.95±4.55), respectively. The initial prostate-specific antigen index, confrontation medical coping modes were the influencing factors of invasive rumination in mPCa patients ( P<0.05). The initial prostate-specific antigen index, course of disease, social support, and confrontation medical coping style were the influencing factors of purposeful rumination in mPCa patients ( P<0.05) . Conclusions:The rumination of mPCa patients is above the medium level, and is influenced by multiple factors under the disease coping mechanism. Clinical medical and nursing staff should combine the clinical situation and characteristics of mPCa patients, provide personalized interventions as early as possible, and assist patients in improving their positive cognitive processing abilities.

Objective:To evaluate the safety and feasibility of the laparoscopic indocyanine green (ICG) fluorescence imaging during the sentinel node navigational surgery for the early gastric cancer.Methods:Patients with <4 cm early gastric cancer were chosen. 0.5 ml ICG (2.5 mg/ml) was preoperatively injected into submucosa around the lesion in four points by the endoscopy. The sentinel lymph node basin including the stained tissue and lymph node (LN) were completely resected guided by the fluorescence mapping under ICG laparoscopy. The specimen was inspected by frozen pathology section. The radical gastrectomy was dependent on the pathology result.Result:Between 2019 and 2021, a total of 18 patients were included in the final analysis. Most tumors (16/18) located in the middle or distal stomach. Median tumor size was 2.0 cm. Lymph vessel invasion was revealed in five cases and perineural invasion in three cases. According to AJCC tumor grading system, tumor depth was classified as Tis in 2 cases, T1a in 5 cases and T1b in 11 cases. Lymph node metastasis (LNM) was revealed in four patients (4/18, 22%). Median sentinel lymph node basins per patient were 2 (range, 1-5). An average 6 (range, 2-13) LNs were harvested in each case, including 6 (1-13) ICG stained LNs and 1 (0-5) non stained LNs. All of four LNM patients were detected by sentinel node navigational surgery. The rate of the sensitivity and accuracy were 100% and 100%, respectively. The median follow-up for the entire group was 58.3 months (0.3-59.9 months), with no recurrence or metastasis observed in any patient.Conclusion:The sensitivity and accuracy of the laparoscopic indocyanine green fluorescence imaging during the sentinel node navigational surgery were satisfactory.

Objective:To analyze the clinical characteristics and prognosis of patients with myelodysplastic syndrome (MDS) with a bone marrow nucleated erythroid cell proportion of greater than or equal to 50% (MDS-E) .Methods:The clinical characteristics and prognostic factors of patients with MDS-E were retrospectively analyzed by collecting the case data of 1 436 newly treated patients with MDS diagnosed in the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences from May 2014 to June 2023.Results:A total of 1 436 newly diagnosed patients with complete data were included in the study, of which 337 (23.5%) patients with MDS-E had a younger age of onset and lower neutrophil and platelet counts compared with those in patients with an erythroid cell proportion of less than 50% (MDS-NE) (all P<0.05). The proportion of MDS cases with ring sideroblasts (MDS-RS) was higher in the MDS-E group than in the MDS-NE group, and multi-hit TP53 mutations were more enriched in the MDS-E group than in the MDS-NE group (all P<0.05). Among patients with MDS-RS, the frequency of complex karyotypes and the TP53 mutation rate were significantly lower in the MDS-E group than in the MDS-NE group (0 vs 11.9%, P=0.048 and 2.4% vs 15.1%, P=0.053, respectively). Among patients with TP53 mutations, the frequencies of complex karyotypes and multi-hit TP53 mutations were significantly higher in the MDS-E group than in the MDS-NE group (87.5% vs 64.6%, P=0.003 and 84.0% vs 54.2%, P<0.001, respectively). Survival analysis of patients with MDS-RS found that the overall survival (OS) in the MDS-E group was better than that in the MDS-NE group [not reached vs 63 (95% CI 53.3-72.7) months, P=0.029]. Among patients with TP53 mutations and excess blasts, the OS in the MDS-E group was worse than that in the MDS-NE group [6 (95% CI 2.2-9.8) months vs 12 (95% CI 8.9-15.1) months, P=0.022]. Multivariate analysis showed that age of ≥65 years ( HR=2.47, 95% CI 1.43-4.26, P=0.001), mean corpuscular volume (MCV) of ≤100 fl ( HR=2.62, 95% CI 1.54-4.47, P<0.001), and TP53 mutation ( HR=2.31, 95% CI 1.29-4.12, P=0.005) were poor prognostic factors independent of the Revised International Prognostic Scoring System (IPSS-R) prognosis stratification in patients with MDS-E. Conclusion:Among patients with MDS-RS, MDS-E was strongly associated with a lower proportion of complex karyotypes and TP53 mutations, and the OS in the MDS-E group was longer than that in the MDS-NE group. Among patients with TP53 mutations, MDS-E was strongly associated with complex karyotypes and multi-hit TP53 mutations, and among TP53-mutated patients with excess blasts, the OS in the MDS-E group was shorter than that in the MDS-NE group. Age of ≥65 years, MCV of ≤100 fl, and TP53 mutation were independent adverse prognostic factors affecting OS in patients with MDS-E.

Objective To analyze the causal relationship between serum sex steroid hormone levels and myopia with the Mendelian randomization(MR)methods.Methods Sex hormone genetic tools classified by sex were publicly availa-ble summarized statistical data from the Genome-wide association study(GWAS)of the UK Biobank Consortium on sex hormone-binding globulin(SHBG),total testosterone(TT),bioavailable testosterone(BT),and estradiol(E2).The GWAS summarized statistical data for myopia were obtained from publicly available data published by the FinnGen Consorti-um R10.All data were downloaded from April 18 to April 31,2024 from the corresponding databases and analyzed.All re-sults from the MR study were mainly analyzed by inverse-variance weighting(IVW)method.Results The study showed that a higher serum SHBG level in European increased the risk of myopia development in women(IVW,OR=1.152,95％CI:1.014-1.308,P=0.029);low serum TT level(IVW,OR=0.821,95％CI:0.697-0.967,P=0.018)and serum BT lev-el(IVW,OR=0.820,95％CI:0.691-0.972,P=0.022)increased the risk of myopia development in women.There was no causal relationship between serum SHBG,TT,and BT levels and myopia in men.There was no causal effect between E2 level and myopia in women and men.The stability of our findings was supported by sensitivity analysis.Conclusion In-creased serum SHBG level and decreased serum TT and BT levels are associated with an increased risk of myopia in women,whereas no such association is found in men.There is no causal relationship between E2 and myopia.

Diabetic retinopathy(DR)is one of the major complications of diabetes mellitus, characterized by neurodegeneration and microangiopathy. Currently, the treatment of DR is mainly focused on the management of late complications and has not achieved the desired clinical outcome. Evidence suggests that the PI3K/AKT pathway, as one of the important intracellular signaling pathways during the cell cycle, is involved in the whole process of DR pathogenesis. This article focuses on the structural composition, activation and blocking pathways, conduction pathways, regulatory mechanisms and biological functions of the PI3K/AKT signaling pathway to review its role in DR and to explore the potential of targeting the PI3K/AKT pathway for the treatment of DR.
