Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder primarily caused by pathogenic variants in the TSC1 or TSC2 genes. It is characterized by multisystem hamartomatous lesions and neuropsychiatric manifestations. Here we report a young male patient with TSC involving multiple organs, caused by a heterozygous frameshift mutation in TSC2 (c.2071delC, p.Arg691Alafs^*7). The patient initially presented with classic facial angiofibromas and hypomelanotic macules, and subsequently developed psychiatric and behavioral disturbances with auditory hallucinations. Neuroimaging revealed an intracranial mass lesion, which was confirmed as a subependymal giant cell astrocytoma on postoperative histopathology following surgery performed at an outside institution. After admission, the patient underwent a comprehensive diagnostic workup, and multidisciplinary treatment evaluation revealed extensive multisystem involve-ment, including the nervous system, skin, kidneys, lungs, heart, eyes, pancreas, liver and bones. Combined with relevant literature, this article discusses the molecular mechanisms, clinical phenotypes, and comprehensive management of TSC, in order to provide a reference for the standardized and individualized management of this disease.

OBJECTIVE To explore the mechanism by which Qingre antai decoction improves pregnancy outcomes of threatened abortion rats with blood heat syndrome. METHODS The pregnant rats were randomly divided into normal group， model group， dydrogesterone group （0.002 g/kg）， and Qingre antai decoction group （44.1 g/kg）， with 13 rats in each group. Except for normal group， other groups were given warming-yang Chinese medicine and corresponding drugs intragastrically， once a day， for 12 consecutive days. On the 13th day of pregnancy， a single intragastric administration of mifepristone （5 mg/kg） was performed to establish a model of threatened abortion with blood heat syndrome. On the 14th day of pregnancy， the abortion rate and uterine coefficient were calculated； the pathological morphology of pregnant uterine was observed； the serum levels of 3，5，3′-triiodothyronine （T3）， thyroid hormone （T4）， thyroid stimulating hormone （TSH）， as well as the levels of vascular endothelial growth factor （VEGF） and nitric oxide （NO） in the pregnant uterus were all determined； the expressions of mRNA and protein related to Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） and phosphatidylinositol 3-kinase （PI3K）/protein kinase B （AKT） pathways were detected. RESULTS Compared with normal group， the model group exhibited endometrial tissue damage， a reduced number of decidual cells， and a significant presence of blood stasis within the uterus； abortion rate， the serum levels of T3， T4 and TSH， the mRNA expressions of JAK2， STAT3 and suppressor of cytokine signaling 3 （SOCS3） as well as protein expressions of p-JAK2， p-STAT3 and SOCS3 in the pregnant uterus were increased significantly （ P ＜0.05）； uterine coefficient， the levels of VEGF and NO in pregnant uterus， mRNA expressions of VEGFR2， PI3K， AKT and endothelial nitric oxide synthase（eNOS）， protein expressions of VEGFR2， PI3K and eNOS as well as phosphorylation level of AKT in the pregnant uterus were significantly reduced （ P ＜0.05）. Compared with model group， the endometrial tissue damage and congestion in the Qingre antai decoction group were significantly improved， and the levels of the aforementioned quantitative indicators were significantly reversed （ P ＜0.05）. CONCLUSIONS Qingre antai decoction can improve the pregnancy outcomes in rats with threatened abortion of blood heat syndrome， the mechanism of which may be associated with inhibiting JAK2/STAT3 pathway and activating PI3K/AKT pathway.

ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective To analyze the situation of monitoring occupational individual radiation doses from external exposure in radiation diagnosis and treatment institutions in a city of Guangdong Province from 2020 to 2022, and to provide a scientific basis for optimizing the radiation protection management in this city. Methods Occupational individual radiation doses from external exposure were monitored using thermoluminescent dosimeters. The recovery rate of personal dosimeters, monitoring results, and data on verification of doses exceeding the investigation level over the three-year period were collected. Data processing and statistical analysis were performed using Excel and SPSS 24.0. Results The average recovery rate of personal dosimeters in the city from 2020 to 2022 was 92.5%. The difference in recovery rates among different institutions in 2021 and 2022 was statistically significant (P<0.05). The mean annual effective dose ranged from 0.20 to 0.36 mSv, with the highest dose observed among the interventional radiology staff (0.42 mSv). The overall distribution of the mean annual effective dose differed significantly across the years (P<0.05). Over the three years, there were 87 instances where individual doses exceeded the investigation level, with 72.4% of these cases attributed to incorrect wearing of dosimeters. Conclusion The individual dose monitoring for radiation workers in this city was generally well-managed. However, it is necessary to further strengthen daily supervision, management, and education on radiation protection, with particular attention given to occupational exposure protection for staff working in interventional radiology and those operating radioactive sources in industrial settings.

Objective To establish quality evaluation method of Andrographis paniculata standard decoction by UPLC. Methods 21 batches of Andrographis paniculata standard decoctions were prepared according to the standardization method of TCM decoction pieces. The UPLC characteristic chromatograms analysis method was established. With andrographolide as a reference, quantitative analysis of multi-components by single marker （QAMS） was established for new neoandrographolide, 14 deoxyandrographolide and dehydrated andrographolide. The results were compared with the external standard method （ESM） to determine the accuracy of the method. Results Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition） was used to analyze and compare the characteristic chromatograms, and seven common peaks were determined and five were identified including luteolin-7-O-β-D-glucuronide, andrographolide, neoandrographolide, 14-deoxyandrographolide and dehydroandrographolide. The RSDs of content results of each component by QAMS and ESM were all within 3%. Conclusion The determination method was reliable and accurate, which could be used to reflect the intrinsic quality of Andrographis paniculata standard decoction comprehensively and provide the basis for the quality evaluation of Andrographis paniculata formula granules and other preparations.

Spastic lower limb paralysis is a common complication following central nervous system injury, including stroke, cerebral palsy, and brain or spinal cord trauma, with high incidence and complex conditions. In recent years, minimally invasive treatment techniques have rapidly advanced, offering new avenues to improve motor function and quality of life for these patients. However, clinical decision-making involves multidisciplinary input, such as rehabilitation, neurosurgery, orthopedics, and standardized treatment guidelines are lacking. This review systematically summarizes commonly used minimally invasive treatments for spastic lower limb paralysis, including their mechanisms, indications, efficacy, and limitations, and compares findings from domestic and international studies. The aim is to provide guidance for clinical decision-making, optimize treatment strategies, and promote development of individualized therapies.

Although video-assisted thoracoscopic surgery (VATS) offers clear advantages, including minimal trauma and rapid recovery, stable intraoperative visualization still depends heavily on the camera assistant. Traditional manual endoscope holding is therefore susceptible to several limitations, including image instability, assistant fatigue, and poor coordination with the primary surgeon. Operating in complex and confined anatomical spaces with a rigid thoracoscope further increases the demands on hand-eye coordination. Thoracoscopic camera-holding technology has progressively evolved from passive support systems to active camera holders and robot-assisted thoracic surgery (RATS) platforms, and is now advancing toward artificial intelligence-driven tracking and intelligent control. Based on this, a series of devices, including multifunctional intelligent assistant arms and active camera-holding arms for thoracic surgery, have been developed and have attracted increasing attention. This article reviews the development of intelligent camera-holding assistant arms and discusses related advances and future directions in the field.

Xuefu zhuyu decoction is a classic formula for promoting blood circulation and resolving blood stasis， characterised by its remarkable ability to treat different diseases with the same approach. Qi stagnation and blood stasis， the primary syndrome for which this formula is indicated， has been found through modern medical research to be intrinsically linked to a wide range of pathophysiological processes， including microcirculatory disorders， abnormalities in hemorheology， inflammatory responses and endothelial dysfunction； which opens up vast scope for the innovative application of traditional formulas. In terms of pharmacological effect and mechanism， the formula exerts a synergistic regulatory effect across multiple key pathological pathways， including the regulation of coagulation function， the maintenance of vascular structure and function， anti-inflammatory and immunomodulatory actions， the mitigation of oxidative stress， and the modulation of programmed cell death （such as pyroptosis and ferroptosis）. This systematically demonstrates its scientific rationale， which is based on integrated regulation through multiple constituents， multiple targets and multiple pathways. In terms of clinical application， the formula has expanded from cardiovascular diseases to multiple disciplines， including gastroenterology， respiratory medicine， urology， neurology， endocrinology， gynaecology and andrology， with evidence-based medical evidence continuing to accumulate. Current research still faces bottlenecks such as a relatively low level of clinical evidence， insufficient systems biology analysis of the mechanisms underlying the compound’s formulation， and a weak correlation between quality control indicators and therapeutic efficacy. Future efforts should focus on conducting multicentre randomised controlled trials for conditions where the formula demonstrates particular efficacy， deepening research into the relationship between integrated pharmacology and spectrum-efficacy relationship， and promoting the precise application and formulation innovation of classical herbal formulas.
