ObjectiveTo explore the establishment of performance assessment indicators for the classification and grading of public health staff in district-level Centers for Disease Control and Prevention (CDCs), and to provide a basis for such evaluations. MethodsThrough literature review and group interviews, performance evaluation indicators were developed based on competency evaluation. Experts were invited to evaluate the weight of performance evaluation indicators for public health staff from different categories, with the average value used to represent the weight of each indicator. ResultsTwenty-nine experts from universities in Shanghai, municipal CDCs, and district CDCs participated, yielding an expert authority coefficient of 0.86. The performance evaluation indicators for department managers were categorized into three levels, with 4 indicators at the primary level, 16 indicators at the secondary level, and 42 indicators at the tertiary level, while those for general staff included 4 primary indicators, 15 secondary indicators, and 36 tertiary indicators. Significant differences were observed in the weight coefficients of the primary indicators (internal operations, professional work, and learning and growth) between department managers and general staff. The top three secondary indicators for department managers were department management, monitoring and prevention, and level of expertise. For mid-level and senior staff, the top three secondary indicators were monitoring and prevention, level of expertise, and research work. The top three secondary indicators for junior staff were monitoring and prevention, professional expertise, and professional attitude. No significant statistical differences were found among tertiary indicators. ConclusionThe developed performance evaluation indicators are reliable. Staff at different levels and classifications should be evaluated using different performance evaluation standards to accurately reflect individual performance and contributions.

Oral squamous cell carcinoma (OSCC) is a malignant tumor that seriously threatens human health. Its typical biological characteristics include strong local invasiveness, high lymph node metastasis rate, and high recurrence rate after treatment. Hepatocyte growth factor (HGF), cellular-mesenchymal to epithelial transition factor (c-Met), and the HGF/c-Met signaling pathway are involved in the regulation of the occurrence and development of OSCC. HGF and c-Met proteins are overexpressed in OSCC, and multiple studies have suggested that they are significantly associated with the malignant characteristics of tumors and poor prognosis. Furthermore, the abnormal activation of the HGF/c-Met signaling pathway (driven by HGF-dependent autocrine/paracrine or non-dependent mechanisms such as MET gene mutations, amplification, fusion, and protein overexpression) can synergistically promote tumor cell invasion, metastasis, and angiogenesis by activating downstream signaling pathways. However, HGF/c-Met can also mediate immune escape by promoting lactate secretion increase, inducing programmed death ligand 1 (PD-L1) expression upregulation, activating and expanding myeloid-derived suppressor cells, and promoting the proliferation of regulatory T cells (Tregs). In addition, the crosstalk between the HGF/c-Met signaling pathway and key pathways such as phosphatidylinositide 3-kinases (PI3K)/protein kinase B (AKT), epidermal growth factor receptor (EGFR), Janus kinase (JAK)/signal transducer and activator of transcription (STAT3), and non-coding RNAs can also promote tumor progression. Currently, three types of targeted drugs have been developed targeting the HGF/c-Met pathway: HGF monoclonal antibody, c-Met monoclonal antibody, and tyrosine kinase inhibitors. Some of these drugs have entered clinical trials. However, the emergence of drug resistance during treatment, especially the bidirectional compensatory activation of alternative signaling pathways such as EGFR, has become a major challenge in clinical practice. This article aims to provide an in-depth analysis of the mechanism of action of the HGF/c-Met pathway in OSCC and its interaction with other pathways, and to review the current research status of existing therapeutic drugs. The aim is to provide an important theoretical basis for developing more effective combined treatment strategies and achieving individualized precise treatment, ultimately improving the clinical prognosis and quality of life of patients.

ObjectiveTo explore the relationship between self-assessed health and age-adjusted Charlson comorbidity index （AICC） in older adults， and to further analyze the differences in this relationship across gender groups. MethodsBased on the China health and retirement longitudinal study （CHARLS） database， this study selected data on basic characteristics， chronic disease status， depressive symptoms， and self-assessed health of older adults aged ≥60 years. Chi-square tests were used to perform a preliminary analysis of the association between these factors and AICC scores. A multifactorial ordered logistic regression model was constructed to assess the effects of each influencing factor on AICC， while multiple linear regression analysis was used to explore the linear relationship between self-rated health and AICC scores. Additionally. Stratified analysis by gender was performed to evaluate gender differences. ResultsA total of 10 911 participants were included， with a mean age of 67.40±5.94 years； 6 249 （57.3%） were male and 4 662（42.7%） were female. The distribution of AICC scores was categorized into low-risk， moderate-risk， higher-risk， and high-risk groups， accounting for 23.5%， 50.2%， 20.6%， and 5.7%， respectively. Multifactorial logistic regression analysis revealed that self-rated health was negatively associated with AICC in the total population and in the male geriatric group （OR=0.843， 95% CI： 0.776， 0.917， P=0.001）， （OR=0.886， 95% CI： 0.796 ， 0.987， P=0.028）， but did not reach statistical significance in the female geriatric group . Linear regression analysis further indicated a significant negative linear relationship between self-rated health and AICC （b=-0.485， 95% CI： -0.516，-0.455， P＜0.001）.This relationship was consistent in both male （b=-0.356， 95% CI： -0.406，-0.305， P＜0.001） and female （b=-0.373， 95% CI： -0.435，-0.310， P＜0.001） subgroups， with a stronger negative association in females. ConclusionSelf-rated health is significantly negatively associated with AICC， and attention should be given to self-rated health in the female geriatric population. Self-rated health can serve as an important tool for identifying elderly group at high risk of comorbidities providing a valuable basis for precise intervention.

ObjectiveTo observe the effect of earthworm protein on the expression of phosphatidylinositol 3-kinase/protein kinase B/nuclear factor E₂-related factor 2 （PI3K/Akt/Nrf2） pathway in the aorta of spontaneously hypertensive rats （SHR） and explore mechanism of earthworm protein in treating hypertensive vascular endothelial dysfunction （VED）. MethodTen 10-week-old Wistar Kyoto （WKY） rats and fifty SHR rats were selected for a week of adaptive feeding. WKY rats were selected as the normal group， and fifty SHR rats were randomized according to body weight into model， valsartan （8×10^-3 g·kg^-1·d^-1）， and high-， medium-， and low-dose （0.2， 0.1， 0.05 g·kg^-1·d^-1， respectively） earthworm protein groups. The normal and model groups were administrated with equal volume of double distilled water by gavage. During the drug intervention period， the general situations of rats in each group were observed and their blood pressure was monitored at specific time points every other week before and after administration. After 8 weeks of drug intervention， enzyme-linked immunosorbent assay was employed to measure the levels of angiotensin-Ⅱ （Ang-Ⅱ） and endothelin-1 （ET-1） in the serum of rats in each group. The corresponding kits were used to determine the levels of nitric oxide （NO）， malondialdehyde （MDA）， glutathione peroxidase （GPX）， superoxide dismutase （SOD）， and ferrous ion （Fe²⁺）. Hematoxylin-eosin （HE） staining was employed to observe the changes in the intima of the aorta. Fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA levels of PI3K， Akt， Nrf2， heme oxygenase-1 （HO-1）， and glutathione peroxidase 4 （GPX4） in the aortic tissue. Western blotting was used to determine the protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 in the thoracic aorta. ResultCompared with the normal group， the model group had decreased body mass， increased irritability， severe endothelial damage， elevated blood pressure and serum levels of Ang-Ⅱ， ET1， MDA， and Fe²⁺ （P<0.01）， lowered NO level （P<0.01）， and down-regulated mRNA and protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 in the aortic tissue （P<0.01）. Compared with the model group， drug intervention caused no significant change in the body mass， calmed the rats， alleviated the endothelial damage， lowered blood pressure and serum levels of Ang-Ⅱ， ET1， MDA， and Fe²⁺ （P<0.01）， elevated the NO level （P<0.05）， and up-regulated the mRNA and protein levels of p-PI3K （Tyr467/199）， PI3K， p-Akt （Ser473）， Akt， Nrf2， HO-1， and GPX4 （P<0.05）. ConclusionThe earthworm protein can exert antihypertensive effects by ameliorating VED in SHR. Specifically， it may regulate the PI3K/Akt/Nrf2 signaling pathway to inhibit oxidative stress and ferroptosis.

Objective To compare endoscopic thyroidectomy via transoral submental approach with open surgery for treating thyroid tumors in terms of the clinical effectiveness.Methods We retrospectively reviewed and analyzed the clinical data and follow-up records of 154 patients in the study,who were hospitalized for thyroidectomy in our hospital from January 2021 to June 2022.Among them,74 cases undergoing endoscopic thyroidectomy via transoral submental approach were assigned to the endoscopic group and 80 cases undergoing traditional open thyroid surgery to the open surgery group.Results All operations were completed successfully and safely in both groups,with no intermediate openings in the endoscopic group.Compared with the open surgery group,the endoscopic group had significantly fewer intraoperative blood losses[(19.46±10.24)mL vs.(32.05±15.87)mL],significantly less incision length[(1.95±0.30)cm vs.(7.05±0.60)cm],significant shorter operative time[(136.66±22.44)min vs.(82.75±15.20)min],and significantly less total postoperative drainage[(111.35±38.92)mL vs.(95.45±36.73)mL](all P＜0.05).Endoscopic patients had superior postoperative pain and cosmetic satisfaction compared to open patients,and the difference was statistically significant(P＜0.05).The two groups had no significant differences in the number of lymph node dissections,parathyroid hormone,and postoperative morbidity between the two groups(P＞0.05).Conclusion The endoscopic thyroidectomy via transoral submental approach can achieve the same clinical effectiveness as the traditional open surgery.However,it is advantageous in reducing intra-operative blood loss,relieving post-operative pain,and achieving a better cosmetic effects of neck incision,thus deserving clinical promotion and application.

BACKGROUND:The imbalance of matrix synthesis and degradation is the main cause of nucleus pulposus degeneration.Small molecule drug Kartogenin(KGN)can restore the balance of matrix synthesis and degradation.Sustained release of KGN using an appropriate drug delivery system is essential for the long-term and effective treatment of KGN.OBJECTIVE:To prepare the injectable hydrogel microspheres by encapsulating KGN with gelatin methacryloyl(GelMA)by microfluidic technology and to investigate the biocompatibility and biological function of nucleus pulposus cells.METHODS:β-Cyclodextrins(β-CD)and KGN were mixed firstly and then mixed with 10%GelMA at a volume of 1:9.Injectable hydrogel microspheres GelMA@β-CD@KGN were prepared by microfluidic technology.The micromorphology of the microspheres was characterized using a scanning electron microscope.The drug release of hydrogel microspheres immersed in PBS within one month was measured.Nucleus pulposus cells were isolated from SD rats and passage 1 cells were cultured in three groups.In the control group,nucleus pulposus cells were cultured separately.In the other two groups,GelMA@β-CD microspheres and GelMA@β-CD@KGN microspheres were co-cultured with nucleus pulposus cells.Cell proliferation was detected by CCK-8 assay and cell survival was detected by live/dead cell staining.Cells were cultured by two complete media with and without interleukin-1β with two kinds of microspheres.mRNA expressions of matrix synthesis and decomposing proteins in nucleus pulposus cells were detected by RT-PCR.RESULTS AND CONCLUSION:(1)Under the scanning electron microscope,the GelMA@β-CD@KGN microspheres after lyophilization were regularly spherical,highly dispersed,uniform in size and full in shape.GelMA@β-CD@KGN microspheres sustained drug release in vitro,reaching 62%of the total drug release at 30 days.(2)Live/dead cell staining showed that GelMA@β-CD@KGN could maintain the activity of nucleus pulposus cells.CCK-8 assay showed that GelMA@β-CD@KGN could promote the proliferation of nucleus pulposus cells.(3)In the complete media with and without interleukin-1β,mRNA expression of aggrecan and type Ⅱ collagen was higher in the GelMA@β-CD@KGN microsphere group than that in the GelMA@β-CD microsphere group(P<0.05,P<0.01);mRNA expression of matrix metalloproteinase 13 and platelet reactive protein disintegrin metallopeptidase 5 was lower than that in the GelMA@β-CD microsphere group(P<0.01).(4)These findings indicate that GelMA@β-CD@KGN microspheres have good biocompatibility and sustained drug release ability.As a drug delivery system,it is a kind of biomaterial with broad application prospects.

ObjectiveTo compare the development status of health facilities in different regions （non-agricultural and agricultural districts）and different types across four dimensions： organizational management， health environment， health activities， and health outcomes， to explore factors that may affect the current development status and summarize effective experiences， and to provide a foundation for the subsequent comprehensive， standardized， and effective promotion of health facility development and tiered and classified management. MethodsInvestigators conducted a health status survey based on the four dimensions for 50 health facilities in 16 districts of Shanghai， representing three types （including government agencies， enterprises， and communities）. Evaluation forms were filled out through on-site observation and document reviews， which were developed in accordance with the Shanghai Health Settings Evaluation Standards （for trial implementation in 2019）. ResultsThe average total score of health facilities in Shanghai was （88.42±11.93） points， with an overall excellence rate of 86.0%. The excellence rate of each dimension， from highest to lowest， were healthy environment （84.0%）， organizational management （82.0%）， health activities （78.0%）， and health outcomes （44.0%）. Health facilities in agricultural districts scored higher in both total score and average score on the organizational management dimension compared to non-agricultural districts. The excellence rate for the organizational management dimension was also higher in agricultural districts than in non-agricultural districts. There was no statistical significance in the total score， the score of each dimension， the overall excellence rate， and the excellence rate of each dimension among different types of health facilities （P>0.05）. ConclusionThe development of health facilities among government agencies， enterprises， and communities in Shanghai has begun to yield positive results. Health facilities in non-agricultural districts should actively draw on the experience of those in agricultural districts， particularly in organizational management， adjust development ideas and planning based on their own realities， so as to continuously improve the levels of development.

The development of health-promoting hospitals is an important part of the Healthy China Initiative， facilitating the transformation of medical institutions from a primary focus on medical and surgical treatments to a patient-centered approach prioritizing public health. To promote the scientific， standardized， and sustainable development of health-promoting hospitals， the Shanghai Municipal Center for Health Promotion， together with Shanghai General Hospital and other institutions， has jointly developed the Standards for the Development of Health⁃promoting Hospitals （Standards） in accordance with the principles of scientific rigor， feasibility， and advancing with the times. The Standards outlines the requirements for the development of health-promoting hospitals across four aspects： organizational and institutional guarantees， creation of a healthy environment， implementation of health education and promotion， and evaluation. It is applicable to all levels and types of public medical institutions in Shanghai， and can also be referred to and implemented by other medical institutions. The introduction of the Standards is of great significance for promoting the formation of a long-term mechanism in health-promoting hospitals. This paper introduces the basis， principles， main content， precautions， and implementation suggestions of the Standards. Taking into account relevant policies and standards， it interprets the technical aspects in the process of developing health-promoting hospitals， which is helpful for medical institutions and their management to better understand and apply the standards in their work.

The long-term presence of non-steroidal anti-inflammatory drugs (NSAIDs) in the environmental water samples not only affects the life safety of aquatic organisms and disturbs the ecoenvironment, but also poses a serious threat to human health. In this study, amino-functionalized Fe3O4 nanoparticles (Fe3O4-NH2) were firstly prepared by solvothermal method. Subsequently, polyethyleneimine (PEI) with a branched chain structure was successfully grafted onto Fe3O4 nanoparticles by Schiff base reaction in aqueous solution at room temperature using glutaraldehyde as a cross-linking agent, and a recyclable PEI-grafted magnetic nano-sorbent (Fe3O4@PEI) was synthesized and applied for the detection of NSAIDs in the environmental water samples. The compositional properties of Fe3O4@PEI were investigated by different characterization methods and the parameters affecting the extraction of NSAIDs were optimized. Due to high adsorption of Fe3O4@PEI for NSAIDs, the quantitative analysis of four NSAIDs in the environmental water samples, ketoprofen, naproxen, diclofenac and tolfenamic acid, was performed in combination with high-performance liquid chromatography. A good linear relationship between the chromatographic peak area and concentration was observed in the range of 1−500 µg/mL. The recoveries of the samples at three different spiked levels ranged from 85.6% to 107.8%; the intra-day precision was less than 7.8% (n=6); and the inter-day precision was less than 9.5% (n=3). The method is simple, rapid, accurate and reliable, and can be used for the analysis of NSAIDs in the environmental water samples．

ObjectiveTo investigate the current situation of health communication carried out by medical institutions in Shanghai through new media platforms such as WeChat， Weibo， Toutiao， Douyin， Kuaishou， Bilibili and WeChat Videos， and to propose targeted measures. MethodsBased on the systematic collection of new media accounts of medical institutions in Shanghai， and through the combination of keyword screening and manual audit， health communication data of medical institutions on new media platforms were determined. ResultsData from 1 117 new media accounts of 162 medical institutions in Shanghai were collected， including 610 WeChat official accounts， 105 WeChat video accounts， 89 Weibo accounts， 18 Bilibili accounts， 198 Douyin accounts， 37 Toutiao accounts， and 60 Kuaishou accounts， totaling 111 853 posts. After keyword sorting and manual screening， a total of 66 761 health science posts were collected， with WeChat Official Accounts， Douyin， and Weibo having the top three highest number of posts. Video-based new media such as Douyin， WeChat Videos， Kuaishou， and Bilibili had a better communication impact than text and image-based new media like WeChat Official Accounts， Weibo， and Toutiao. Among them， Douyin and Toutiao were the best platforms for video and text-image-based new media， respectively. ConclusionMedical institutions in Shanghai recognize the importance of new media in health communication and have made full use of various media platforms to carry out health communication，having a certain impact on health education. In the future， medical institutions should choose appropriate platforms based on target audiences and content characteristics， fully leverage the advantages of various platforms， explore innovative communication strategies， promote the dissemination of health knowledge， and enhance the health literacy of the public.
