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.

Objective:To dynamically study the iodine nutritional status of pregnant women in Guangxi Zhuang Autonomous Region (referred to as Guangxi), providing a basis for timely implementation of targeted prevention and control measures and scientific adjustment of intervention strategies.Methods:From 2015 to 2022, a survey was conducted in Guangxi on a county-by-county basis. One township/street was selected from each county based on the east, west, south, north, and center directions, and 20 pregnant women were selected from each township/street. Salt and urine samples were collected from the homes of pregnant women to detect salt and urine iodine levels.Results:A total of 78 034 pregnant women were surveyed from 2015 to 2022, with a median salt iodine concentration of 24.4 mg/kg. The overall coverage rate of iodized salt, qualification rate of iodized salt, consumption rate of qualified iodized salt, and the rate of non-iodized salt were 99.0% (77 250/78 034), 95.9% (74 105/77 250), 95.0% (74 105/78 034), and 1.0% (784/78 034), respectively. The comparison of qualified iodized salt consumption rates in different regions (cities) showed statistically significant difference (χ 2 = 3 801.28, P < 0.001), with Baise City had the highest (98.1%, 8 328/8 488) and Beihai City had the lowest (70.7%, 1 909/2 700); except for Beihai City, the consumption rate of qualified iodized salt in all other cities was over 90%. The median urinary iodine level among pregnant was 148 μg/L. The difference in urinary iodine levels among pregnant women between different years was statistically significant ( H = 2 516.52, P < 0.001), with the highest level in 2020 (169 μg/L) and the lowest level in 2015 (126 μg/L). From 2020 to 2022, the median urinary iodine level for pregnant women was ≥150 μg/L, while from 2015 to 2019, it was < 150 μg/L. There were statistically significant difference in urinary iodine levels among pregnant women in different regions (cities, H = 495.69, P < 0.001), with Liuzhou City and Guilin City had the highest levels (both at 156 μg/L), and Beihai City had the lowest level (132 μg/L). The median urinary iodine levels of pregnant women in the early, middle, and late stages of pregnancy were 154, 147, and 154 μg/L, respectively. There were statistically significant differences in urine iodine levels among pregnant women in different pregnancy stages ( H = 158.64, P < 0.001), with mid pregnancy being lower than early and late pregnancy ( P < 0.017). Conclusions:The overall iodine nutrition level of pregnant women in Guangxi is slightly insufficient, especially in coastal cities such as Beihai City. We should continue to adhere to the strategy of using iodized salt to prevent and control iodine deficiency disorders. At the same time, we should strengthen health education for pregnant women, and adopt targeted and precise iodine supplementation measures for pregnant women in different regions and during pregnancy.

Objective:To investigate the awareness and behavior of iodine deficiency disorders prevention and control knowledge among pregnant women in Guangxi Zhuang Autonomous Region (referred to as Guangxi), and provide a basis for further targeted health education.Methods:From June to August 2023, a cross-sectional study method was used conduct a questionnaire survey about the awareness and behavior of iodine deficiency disorders prevention and control knowledge on 819 pregnant women who underwent prenatal or inpatient examinations at county people's hospitals, maternal and child health centers, and township health centers in 14 counties of 7 cities in Guangxi.Results:A total of 819 valid questionnaires were collected in this survey. The score of iodine deficiency disorders prevention and control knowledge among pregnant women was (6.1 ± 2.8) points, with an awareness rate of 62.4% (511/819). There were statistically significant differences in the awareness rate of iodine deficiency disorders prevention and control knowledge among pregnant women of different ages, residence areas, fertility status, educational level, employmnet status, occupation, and per capita monthly income(χ 2 = 9.17, 37.51, 5.15, 87.12, 54.22, 50.17, 67.623, P < 0.05). There were statistically significant differences in various behaviors related to salt consumption habits, home salt packaging, awareness of which salt to eat, choices made when buying salt, salt preservation habits, whether or not the subject had eaten iodine-rich foods in the week before the survey, how often they had eaten iodine-rich foods in the year before the survey, and whether or not they had actively learned about iodine knowledge during pregnancy or before pregnancy between pregnant women with different levels of knowledge (χ 2 = 21.64, 12.81, 101.79, 123.20, 36.78, 59.76, 109.14, 98.10, P < 0.05). The main ways to obtain knowledge on prevention and control of iodine deficiency disorders were medical workers(71.3%, 381/534), traditional media(54.5%, 291/534), community advocacy(53.4%, 285/534), news client and new media(50.2%, 268/534). Conclusions:The overall awareness rate of iodine deficiency disorders prevention and control knowledge among pregnant women in Guangxi is not high. We should strengthen health education for pregnant women, especially young and multiparous women, those with low education and low income.

Objective:To investigate potential effective components of traditional Chinese medicine and their molecular mechanisms of action in the anti-angiogenic treatment of Kaposi′s sarcoma based on network pharmacology, and to predict key targets and signal pathways in the anti-angiogenic treatment of Kaposi′s sarcoma with traditional Chinese medicine.Methods:According to the previous network pharmacology-based analysis results, main chemical components and targets of Rhizoma Polygoni Cuspidati, Cortex Mori, Rhizoma Smilacis Glabrae and Fructus Perillae were obtained by using the traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP); potential therapeutic targets for angiogenesis and Kaposi′s sarcoma were obtained by searching the GeneCard, OMIM, DrugBank and TTD databases, and a Venn diagram was constructed to obtain targets for the interaction between Kaposi′s sarcoma and anti-angiogenic drug components; a protein-protein interaction model was constructed using the STRING 11.5 platform; the Cytoscape 3.6.0 software was used to construct the component-target visual network. Meanwhile, the Metascape platform was used to analyze the Gene Ontology (GO) functions and the enrichment of Kyoto Encyclopedia of Genes and Genome (KEGG) -based pathways. The main active ingredients and core targets obtained through the above analyses were then verified by molecular docking. Results:The core components of anti-Kaposi′s sarcoma angiogenesis drugs were resveratrol (degree: 142), quercetin (degree: 141), kaempferol (degree: 56), luteolin (degree: 56), β-sitosterol (degree: 37), arachidonic acid (degree: 36), naringenin (degree: 36), etc., and the core target was prostaglandin-endoperoxide synthase 2 (PTGS2). KEGG analysis revealed that the cancer signaling pathways were the important pathways related to the inhibiton of angiogenesis in Kaposi′s sarcoma; functional enrichment analysis showed that the positive regulation of cell migration was the most significantly enriched GO term in the biological process category. Molecular docking results showed that resveratrol, quercetin, kaempferol and luteolin had good affinity with PTGS2, especially quercetin and luteolin exhibited the strongest binding abilities to PTGS2, with the binding energies being -9.4 and -9.5 kcal/mol, respectively.Conclusion:This study showed that the 4 traditional Chinese medicines recorded in TCMSP (including Rhizoma Polygoni Cuspidati., Cortex Mori, Rhizoma Smilacis Glabrae and Fructus Perillae) may play an anti-angiogenic role by regulating cancer signaling pathways and acting on targets such as PTGS2, and predicted the possible anti-angiogenesis mechanisms of traditional Chinese medicines in Kaposi′s sarcoma.

As a representative chemotherapeutic drug, docetaxel (DTX) has been used for breast cancer treatment for decades. However, the poor solubility of DTX limits its efficacy, and the DTX based therapy increases the metastasis risk due to the upregulation of C-X-C chemokine receptor type 4 (CXCR4) expression during the treatment. Herein, we conjugated CXCR4 antagonist peptide (CTCE) with DTX (termed CTCE-DTX) as an anti-metastasis agent to treat breast cancer. CTCE-DTX could self-assemble to nanoparticles, targeting CXCR4-upregulated metastatic tumor cells and enhancing the DTX efficacy. Thus, the CTCE-DTX NPs achieved promising efficacy on inhibiting both bone-specific metastasis and lung metastasis of triple-negative breast cancer. Our work provided a rational strategy on designing peptide-drug conjugates with synergistic anti-tumor efficacy.

OBJECTIVE:
To investigate the influence of buried thread nasal augmentation on dorsal soft tissue of nose and revision rhinoplasty.
METHODS:
A clinical data of 29 patients requesting revision rhinoplasty after buried thread nasal augmentation, who were admitted between July 2017 and July 2019 and met the selection criteria, was retrospectively analyzed. All patients were female with an average age of 26.8 years (range, 18-43 years). The patiens were admitted to the hospital at 3-48 months after buried thread nasal augmentation (median, 15 months). Among them, there were 18 cases of insufficient nasal tip projection, 22 cases of insufficient nasal root projection, 7 cases of threads ectasia, 5 cases of threads exposure, 3 cases of infection, and 10 cases with two or more conditions. There were 9 cases of combined short nose deformity, 1 case of spherical hypertrophy of the nasal tip, 3 cases of deviation of the nasal columella, 3 cases of excessive width of the nasal base, and 1 case of nasal hump. Three infected patients only underwent threads removal and debridement. The rest patients underwent revision rhinoplasty, and the dorsum of the nose was made with polytetrafluoroethylene expansion; the tip of the nose was reshaped by taking autologous rib cartilage and alar cartilage in 16 cases, and by taking autologous septal cartilage and alar cartilage in another 10 cases. The threads and surrounding tissue specimens removed during operation were subjected to histologic observation. Nasal length and nasal tip projection were measured after revision rhinoplasty and the ratio was calculated to evaluate the nasal morphology; patient satisfaction was evaluated using the Likert 5-grade scale.
RESULTS:
Patients were followed up 12-48 months (mean, 18 months). Inflammation was controlled in 3 patients with infections caused by buried thread nasal augmentation. The remaining 26 patients had satisfactory results immediately after revision rhinoplasty. Before revision rhinoplasty and at 7 days and 6 months after revision rhinoplasty, the nasal length was (4.11±0.34), (4.36±0.25), and (4.33±0.22) cm, respectively; the nasal tip projection was (2.34±0.25), (2.81±0.18), and (2.76±0.15) cm, respectively; and the nasal tip projection/nasal length ratio was 0.57±0.08, 0.65±0.05, and 0.64±0.04, respectively. There were significant differences in the nasal length and the nasal tip projection between time points ( P<0.05). There was a significant difference in the nasal tip projection/nasal length ratio between pre- and post-operation ( P<0.05), but there was no significant difference between 7 days and 6 months after operation ( P>0.05). The Likert score for satisfaction ranged from 1.5 to 5.0 (mean, 4.05). During follow-up period of 26 patients, no nasal prosthesis was exposed, and the shape of the nose was stable, and the nasal skin of 5 patients with exposed threads could be seen with different degrees of scarring; there was no infection, cartilage resorption, and no cartilage deformation, displacement, or exposure. Histological observation showed that absorbable threads were not only absorbed after implantation, but also with the prolongation of time, the inflammatory changes in the surrounding tissues caused by decomposition and absorption of the threads showed a gradual aggravation of the first, the heaviest inflammatory reaction in 6 to 12 months, and then gradually reduce the trend.
CONCLUSION
After implantation of the absorbable thread into the subcutaneous tissue of the nasal dorsum, the nature of the thread is different from the body's own tissue, which will affect the soft tissue compliance of the nasal dorsum. The degradation and absorption of the thread will stimulate the infiltration of inflammatory cells and the proliferation of fibroblasts in the surrounding tissue and then form scar tissue, which will affect the design and effect of revision rhinoplasty.

Endocrinology and Metabolism 2023;38(5):493-503
The growing recognition of mitochondria’s crucial role in the regulation of white adipose tissue remodeling and energy balance underscores its significance. The marked metabolic diversity of mitochondria provides the molecular and cellular foundation for enabling adipose tissue plasticity in response to various metabolic cues. Effective control of mitochondrial function at the cellular level, not only in thermogenic brown and beige adipocytes but also in energy-storing white adipocytes, exerts a profound influence on adipose homeostasis. Furthermore, mitochondria play a pivotal role in intercellular communication within adipose tissue via production of metabolites with signaling properties. A more comprehensive understanding of mitochondrial regulation within white adipocytes will empower the development of targeted and efficacious strategies to enhance adipose function, leading to advancements in overall metabolic health.

Depressive disorder ranks as a major bur-den of disease worldwide,yet the current antidepressant medications are limited by frequent non-responsiveness and significant side effects.The lateral septum(LS)is thought to control of depression,however,the cellular and circuit substrates are largely unknown.Here,we identified a subpopulation of LS GABAergic adenosine A2A receptors(A2AR)-positive neurons mediating depres-sive symptoms via direct projects to the lateral habenula(LHb)and the dorsomedial hypothalamus(DMH).Activa-tion of A2AR in the LS augmented the spiking frequency of A2AR-positive neurons leading to a decreased activation of surrounding neurons and the bi-directional manipula-tion of LS-A2AR activity demonstrated that LS-A2ARs are necessary and sufficient to trigger depressive pheno-types.Thus,the optogenetic modulation(stimulation or inhibition)of LS-A2AR-positive neuronal activity or LS-A2AR-positive neurons projection terminals to the LHb or DMH,phenocopied depressive behaviors.Moreover,A2AR are upregulated in the LS in two male mouse mod-els of repeated stress-induced depression.This identifica-tion that aberrantly increased A2AR signaling in the LS is a critical upstream regulator of repeated stress-induced depressive-like behaviors provides a neurophysiological and circuit-based justification of the antidepressant poten-tial of A2AR antagonists,prompting their clinical transla-tion.

BACKGROUND:
Research on the relationship between residential altitude and hypertension incidence has been inconclusive. Evidence at low altitudes (i.e., <1,500 m) is scarce, let alone in older adults, a population segment with the highest hypertension prevalence. Thus, the objective of this study is to determine whether hypertension risk may be affected by altitude in older adults living at low altitudes.
METHODS:
This prospective cohort study collected data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS). We selected 6,548 older adults (≥65 years) without hypertension at baseline (2008) and assessed events by the follow-up surveys done in 2011, 2014, and 2018 waves. The mean altitude of 613 residential units (county or district) in which the participants resided was extracted from the Digital Elevation Model (DEM) of the National Aeronautics and Space Administration (NASA) and was accurate to within 30 m. The Cox regression model with penalized splines examined the linear or nonlinear link between altitude and hypertension. A random-effects Cox regression model was used to explore the linear association between altitude and hypertension.
RESULTS:
The overall rate of incident hypertension was 8.6 per 100-person years. The median altitude was 130.0 m (interquartile range [IQR] = 315.5 m). We observed that the exposure-response association between altitude and hypertension incidence was not linear. The shape of the exposure-response curve showed that three change points existed. Hypertension risk increased from the lowest to the first change point (247.1 m) and slightly fluctuated until the last change point (633.9 m). The risk decreased above the last change point. According to the categories stratified by the change points, altitude was only significantly associated with hypertension risk (hazard ratio [HR] = 1.003; 95% confidence interval [CI] = 1.002-1.005) under the first change point (247.1 m) after adjusting for related covariates.
CONCLUSION
Our study found that the association between altitude and hypertension risk might not be linear. We hope the further study can be conducted to confirm the generality of our findings.
