Cardiovascular diseases pose a serious threat to public health, and their prevalence is on the rise year by year. Vascular aging is an independent risk factor for cardiovascular diseases, and endothelial cell senescence is an early event in vascular aging. Its occurrence can lead to endothelium-dependent vasodilation dysfunction, reduced vascular permeability, and the release of the senescence-associated secretory phenotype (SASP). These vascular pathological changes further damage the vascular media, leading to vascular remodeling and reduced compliance, accelerating the progression of atherosclerosis, and ultimately resulting in cardiovascular diseases such as coronary heart disease and hypertension. Recent research of the investigators has revealed that SNRK, a new member of the AMPK family of cellular energy sensors, plays a key regulatory role in vascular development. Based on this finding, the investigators propose the scientific hypothesis that SNRK responds to both physiological and pathological aging stimuli through differential mechanisms and regulates the process of endothelial cell senescence. In this study, the investigators will explore the correlation between SNRKAS and carotid vascular structure and endothelial function by measuring the levels of the SNRK upstream lncRNA (SNRKAS) in participants' peripheral blood, in conjunction with carotid ultrasound examinations. The findings will provide a solid scientific basis for elucidating new mechanisms underlying the onset and progression of vascular aging and for identifying novel therapeutic targets.

This randomized, double-blind, single-dummy, multicenter clinical study, led by Principal Investigator Xue Fengxia at Tianjin Medical University General Hospital (sponsor and primary trial institution) and funded by Zhuzhou Qianjin Pharmaceutical Co., Ltd., evaluates the safety and efficacy of FuKe Qianjin Capsules combined with standard antibiotic therapy for chronic endometritis (CE) in women aged 20-40 years. CE, a common gynecological inflammation marked by uterine plasma cell infiltration from bacterial infection, is linked to infertility, repeated implantation failure (RIF), and recurrent miscarriage (RM); it is often underdiagnosed due to non-specific symptoms, and first-line doxycycline therapy is limited by antibiotic resistance and high recurrence. FuKe Qianjin Capsules, a nationally recognized Chinese herbal medicine for gynecological inflammations, align with traditional Chinese medicine (TCM) treatment principles for CE (damp-heat stasis with qi and blood deficiency) and reduce antibiotic resistance per domestic research. Approximately 300 eligible participants (confirmed CE via hysteroscopy/pathology, matching TCM syndrome, regular menstrual cycles, informed consent) will be enrolled across 10-15 Chinese centers, with exclusion for acute infections, gynecological malignancies/ severe uterine lesions, organ dysfunction, uncontrolled systemic diseases, pregnancy/lactation, drug hypersensitivity, or recent trial participation. All receive 14 days of oral doxycycline (100mg twice daily) and are randomized 1:1 to two double-blind groups (150 each): Experimental Group (56 days of FuKe Qianjin Capsules, 0.4g/capsule, 2 capsules three times daily) or Control Group (56 days of matched capsule placebo). The study includes a 28-day screening period, 56-day treatment phase, and 6-month post-treatment follow-up (in-person visits at Day 28±5/56±7; telephone/outpatient follow-up at 3/6 months). Efficacy assessments (hysteroscopy, TCM scoring, ultrasound), safety monitoring (vital signs, blood work, pregnancy testing), adverse event recording, and medication adherence checks occur at all visits, with ultrasound-confirmed clinical pregnancy rate as the key post-treatment outcome. The team monitors known drug adverse effects (mild gastrointestinal/skin/neurological symptoms for the capsules; gastrointestinal/photosensitivity/rare liver/blood issues for doxycycline) and hysteroscopy risks (mild bleeding, rare perforation), with emergency protocols in place. Participants may withdraw voluntarily at any time with no impact on regular care; all data/specimens are confidential, de-identified, and used only for study research (no commercial use). Overseen by the hospital's Institutional Ethics Committee and compliant with national research standards, the study's primary goal is to confirm the combined regimen's superior safety and efficacy over antibiotic monotherapy for CE, as well as its ability to improve reproductive outcomes and reduce recurrence. A positive result will establish this integrated Chinese-Western medicine approach as an evidence-based CE treatment, reducing antibiotic resistance and enhancing reproductive health for affected women, especially those with infertility, RIF, or recurrent miscarriage.

Acute lung injury is a common complication of subarachnoid hematoma (SAH), and a significant risk factor for death in patients with SAH. Unlike neurogenic pulmonary edema and pneumonia following brain injury, the clinical causes of pulmonary injury after SAH are not intracranial hypertension or pulmonary infection. Its occurrence is influenced by the release of catecholamines, the regulatory function of the hypothalamic-pituitary-adrenal (HPA) axis and systemic inflammatory response, but the specific mechanisms are still unclear. Therefore, delving into the pathological mechanisms of SAH-induced lung injury and developing therapeutic strategies based on the findings is of great importance to improve the prognosis of patients. Abnormal accumulation of hyaluronic acid in the lungs has been reported to be closely related to the pathological progression of various pulmonary injury diseases, such as chest trauma, pulmonary infection and chronic obstructive pulmonary disease. From this, the present research is aimed to explore the levels and dynamic changes of hyaluronic acid in the bronchoalveolar lavage fluid and blood of patients with acute lung injury following SAH, and to analyze its correlation with the prognosis of pulmonary complications, thereby providing assistance for the clinical diagnosis and treatment of SAH.

The goal of this observational study is to learn if a traditional Chinese herbal medicine (Xuanfei Jiangzhuo Decoction) works to help older adults recover from a COPD flare-up caused by the flu (influenza virus). The main questions it aims to answer are: Does the herbal medicine help participants feel better and recover faster? Does it lower the chance of getting a second infection from bacteria? Is the herbal medicine safe to use? Researchers will compare participants who choose to take the herbal medicine along with their standard flu treatment (Oseltamivir or Baloxavir) to participants who only take the standard flu treatment (Oseltamivir or Baloxavir). Participants will: Take the herbal medicine (a liquid drink) twice a day for 5 days, or just take their standard flu medicine for 5 days. Visit the clinic 4 times over 28 days for checkups and tests. Provide blood and stool samples to help researchers understand how the medicine affects the body and gut health. Answer simple questions about their cough, breathing, and energy levels.

In the field of diagnosing brain neurodegenerative diseases, it is now a well-established practice to inject positron-emitting tracers into the human body. These tracers bind to specific target proteins, allowing their distribution to be visualized via PET imaging. Currently, several research groups worldwide are engaged in developing and clinically validating their own tau imaging agents. This clinical research project aims to visualize abnormal tau pathology in the living human brain using \[18F\]NIDF PET imaging. \[18F\]NIDF is a 2-arene-azaindole-based tracer that offers stronger binding affinity to tau neurofibrillary tangles and reduced non-specific/off-target binding compared to existing tau-PET imaging agents. The study primarily focuses on evaluating the safety and diagnostic efficacy of \[18F\]NIDF PET imaging in human subjects.

\[18F\]FT8, a derivative of 1-(4-pyridyl)-4-piperazinyl arene (\[18F\]TPZA), exhibits high affinity for AL amyloid in myocardial tissue sections and shows no significant binding to transthyretin amyloid. By comparing its diagnostic performance against established clinical methods, including echocardiography, contrast-enhanced MRI, and relevant laboratory tests, this study aims to establish \[18F\]FT8 as the basis for a robust PET protocol for the direct visualization and differential diagnosis of AL amyloidosis . The study preimarily evaluates the safety and diagnostic efficacy of \[18F\]FT8 PET imaging in human subjects.

In order to solve the bottleneck problems of"zero balance displacement"and"large variation of breastmilk"in the study of iodine EAR of pregnant women, lactating women and infants, firstly, this study intends to clarify the rate of metabolism and distribution of iodine during pregnancy by 125I tracer, SPECT/CT in vivo small animal imaging and γ counting study. Then, the iodine balance study in rats was conducted to verify the degree of "zero balance value displacement"caused by the difference of iodine absorption and store in different organs and tissues under different iodine exposure levels, so as to determine the iodine selection conditions of subjects in the population experiment. To determine the EAR of pregnant women by optimizing the population iodine balance experiment. Secondly, we proposed to study the regulatory mechanism of NIS and Pendrin in the mammary gland of lactating rats under different iodine nutrition levels to clarify the range of breastmilk iodine compensation. Mammary cell experiments intend to clarify the mutual regulations of iodine nutrition, oestrogen, and NIS and Pendrin. Based on the results of animal and cellular experiments, and the effect of genetic, oestrogen and iodine status were considered, a cross-sectional study of lactating women was conducted to determine the normal reference range of breastmilk iodine after screening out the people with abnormal indicators. This study will solve the bottleneck problems and difficulties in the iodine RNI research for pregnant women, lactating women and infants, found the iodine nutritional compensatory mechanism under special physiology, and provide the scientific basis for obtaining the accurate EAR basic data and the revision of iodine DRIs.
