Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Breast cancer (BC) is most commonly diagnosed worldwide. Liquiritigenin is a flavonoid found in various species of the Glycyrrhiza genus, showing anti–tumor activity. This article was to explore the influences of liquiritigenin on the biological behaviors of BC cells and its underlying mechanism. BC cells were treated with liquiritigenin alone or transfected with oe-HSP90 before liquiritigenin treatment. RT-qPCR and Western blotting were employed to examine the levels of HSP90, Snail, E-cadherin, HSC70, and LAMP-2A. Cell viability, proliferation, migration, and invasion were evaluated by performing MTT, colony formation, scratch, and Transwell assays, respectively. Liquiritigenin treatment reduced HSP90 and Snail levels and enhanced E-cadherin expression as well as inhibiting the proliferation, migration, and invasion of BC cells. Moreover, liquiritigenin treatment decreased the expression of HSC70 and LAMP-2A, proteins related to chaperone-mediated autophagy (CMA). HSP90 overexpression promoted the CMA, invasion, and migration of BC cells under liquiritigenin treatment. Liquiritigenin inhibits HSP90-mediated CMA, thereby suppressing BC cell growth.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective: To investigate the association between obesity and insomnia among adults, so as to provide insights into obesity control and sleep health improvements among adult populations. Methods: Sixteen communities were randomly sampled from Longgang District, Shenzhen City using a multistage cluster sampling method, and permanent residents at ages of 18 years and older living in these communities were recruited as study subjects. Subjects' gender, age, educational level and marital status were collected using a self-designed questionnaire, and the body mass index ( BMI) was calculated. The sleep quality was evaluated using the Insomnia Severity Index ( ISI ), and the correlation between obesity and insomnia was evaluated using a multivariable logistic regression model. Results: A total of 10 434 questionnaires were allocated, and 9 425 valid questionnaires were recovered, with an effective recovery rate of 90.33%. The respondents included 3 448 men ( 36.58% ) and 5 977 women ( 63.42% ), and 6 940 respondents ( 73.63% ) were at ages of 18 to 44 years. There were 778 respondents with underweight ( 8.25% ), 5 522 with normal weight ( 58.59% ), 2 209 with overweight ( 23.44% ) and 916 with obesity ( 9.72% ). Among all respondents, 1 149 respondents were detected with insomnia, with a detection rate of 12.19%, including 839 subjects with mild insomnia ( 8.90% ), 247 subjects moderate insomnia ( 2.62% ) and 63 subjects with severe insomnia ( 0.67% ). Multivariable logistic regression analysis showed a statistically significant correlation between obesity and insomnia ( OR=2.179, 95%CI: 1.824-2.603 ). Conclusions There is a significant correlation between obesity and insomnia. Body weight management and sleep health education shall be intensified among adults.

OBJECTIVE：To investigate th e cognition ，attitude and behavior of part of drug practitioners in Shenzhen on compensation of adverse drug reaction （ADR）injury，and to provide relevant reference for the establishment of ADR injury compensation system. METHODS ：Taking marketing authorization holder （MAH），staff of medical institutions at the second level or above and drug regulatory authorities in the relevant meeting held in Shenzhen in 2018 as objects ，on-the-spot anonymous investigation of “questionnaire star ”was used to collect and analyze the cognition ，attitude（including attitude towards ADR compensation and ADR compensation system ）and behavior of the above-mentioned personnel to ADR compensation. The relevant suggestion was put forward. RESULTS & CONCLUSIONS ：A total of 172 questionnaires were collected （all being valid ）. In term of cognition ，the respondents generally had high awareness of ADR （response rate of ADR concept was 82.0％）. In term of attitude to ADR injury compensation ，100 respondents（58.1％）believed that ADR after medication should be compensated ，and 147 respondents（85.5％）believed that compensation should be made for serious and fatal adverse reactions. In term of attitude to ADR injury compensation system ，respondents thought that ADR damage compensation funds be undertaken by MAH for 131 case times （76.2％）. As for the difficulties in the implementation of ADR compensation ，it was considered that the evaluation of the correlation between adverse reactions and drugs led to the difficulties in the implementation of ADR compensation （143 case times ， 83.1％）；most respondents thought that the first thing to do in the implementation of ADR compensation system was to implement laws and regulations （145 case times ，84.3％）. In term of behavior ，104 respondents（60.5％）had processed costs due to ADR ， most of whom chose self-resolved （85 cases，81.7％）；112 respondents （65.1％） chose to inform medical personnels or pharmacies directly. It is suggested that the relevant departments in Shenzhen should explore and establish ADR injury compensation mechanism in Shenzhen by establishing a public oriented platform and mechanism for ADR science popularization （setting up relevant departments ，supervising the public propaganda of news media ，expanding the public propaganda to the commu nity），exploring and establishing ADR injury compensation mechanism （setting up a special legislative pilot of ADR injury regulations ，setting up ADR injury appraisal committee ），and increasing the investment in ADR testing （fully using of “Internet+”Big Data ，allocating special funds ）.

In order to diagnose and evaluate the human spinal lesions through the paravertebral muscles, a paravertebral muscle monitoring system based on surface EMG signals was designed. The system used surface mount electrodes to obtain the surface myoelectric signal (sEMG) of paravertebral muscle. The signal was filtered and amplified by the conditioning circuit. The signal was collected by the microcontroller NRF52832 and was sent to the mobile APP. After the signal was preprocessed by the wavelet threshold denoising algorithm in APP, the time and frequency characteristics of the sEMG signal reflecting the functional state of the muscle were extracted. The calculated characteristic parameters was displayed in real time in the application interface. The experimental results show that the system meets the design requirements in analog signal acquisition, digital processing of signals and calculation of characteristic parameters. The system has certain application value.
