ObjectiveTo investigate the clinical efficacy and mechanisms of Qigui Didang decoction in the treatment of kidney collateral stasis syndrome in patients with stage Ⅲ-Ⅳ diabetic kidney disease （DKD） in a real-world setting. MethodsPatients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome admitted to Beijing Aerospace General Hospital from January 2022 to December 2024 were selected for clinical study. According to treatment methods， patients were divided into the Qigui Didang decoction group （Qigui Didang decoction + conventional treatment） and the control group （conventional treatment alone）. A 1∶1 propensity score matching （PSM） method was used to reduce bias caused by confounding factors. Clinical efficacy， traditional Chinese medicine （TCM） symptom scores， renal function indicators， mRNA expression related to pathway mechanisms， glycolipid metabolism indices， and adverse reactions were compared between the two groups. ResultsA total of 120 patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome were included， including 62 cases in the Qigui Didang Decoction group and 58 cases in the control group. Before matching， there were statistically significant differences between the two groups in DKD stage， baseline urinary albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， and estimated glomerular filtration rate （eGFR） （P<0.05）. After matching， 47 cases were included in each group， and there was no statistically significant difference in baseline data between the two groups. After matching， the total clinical effective rate of the Qigui Didang decoction group was significantly higher than that of the control group （χ²=4.681， P<0.05）. Compared with data before treatment， the scores of primary and secondary TCM symptoms in the Qigui Didang decoction group were significantly decreased （P<0.05）. Compared with data before treatment， serum creatinine （SCr）， 24 h-UTP， and UACR levels were significantly decreased， while eGFR was significantly increased in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， the mRNA expression of silent information regulator 1 （Sirt1） was significantly upregulated， while the mRNA expression of nuclear factor-kappa B （NF-κB） and tumor suppressor protein p53 （p53） was significantly downregulated in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， fasting plasma glucose （FPG）， 2-hour postprandial plasma glucose （2 hPG）， glycated hemoglobin A1c （HbA1c）， total cholesterol （TC）， triglycerides （TG）， and low-density lipoprotein cholesterol （LDL-C） levels were decreased， while high-density lipoprotein cholesterol （HDL-C） levels were increased （P<0.05）. There was no statistically significant difference in adverse reactions between the two groups. ConclusionQigui Didang decoction combined with conventional treatment can significantly improve renal function， glycolipid metabolism， and TCM syndromes in patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome， with good safety. The mechanism may be related to the regulation of the Sirt1/NF-κB/p53 signaling pathway.

OBJECTIVE To optimize the management model of drugs used in investigator-initiated trial(IIT).METHODS With benchmarking analysis,based on the practical work experience of a tertiary specialized hospital in the field of IIT drug management in Shanghai,a thorough review was conducted,involving relevant laws,regulations,and academic literature to establish benchmark criteria and the evaluation standards.Starting from the initiation of IIT projects,a detailed comparative analysis of key processes was carried out,such as the receipt,storage,distribution,use and recycling of drugs for trial.The deficiencies in the current management of IIT drugs were reviewed in detail and a series of optimization suggestions were put forward.RESULTS It was found that the authorized records of drug management were missing,the training before project implementation was insufficient,and the records of receipt and acceptance of IIT drugs were incomplete.In light of these existing problems,improvement measures were put forward,including strengthening the training of drug administrators and stipulating that only drug administrators with pharmacist qualifications be eligible to inspect and accept drugs,etc.The related systems were improved,and 17 key points of quality control for the management of IIT drugs were developed.CONCLUSIONS A preliminary IIT drug management system for medical institutions has been established,which helps to improve the institutional framework of medical institutions in this field.

Image-guided fine needle aspiration technique has been widely used in various diagnostic and therapeutic procedures. However, if the target of the puncture is a malignant tumor, it is possible that tumor cells attached to the surface and core of the puncture needle may fall off, causing tumor cells to enter the puncture needle path and form needle path implantation metastasis, thereby reducing the patient's quality of life and treatment effectiveness. In this article, we have identified the causes of needle tract metastasis, elaborated on relevant measures to prevent tract metastasis, summarized the operating standards of fine needle puncture and the treatment methods for needle tract metastasis, in order to reduce the incidence of needle tract metastasis, improve the quality of life and treatment effectiveness of patients.

Abstract Low level light therapy utilizes the photochemical effect of red light to induce reactions in the irradiated body tissue to achieve the therapeutic effect. Myopia and amblyopia are diseases which threaten the eye health of children and adolescents. Red light has been used to treat amblyopia for decades. Recently, its application in myopia prevention and control has become a new hotspot. This review summarizes the application of low level red light in children and adolescents with myopia and amblyopia from the aspects of intervention mode, effect, factors, mechanism and safety to provide reference for future researches.

Isochrysis galbana is considered an ideal bait for functional foods and nutraceuticals of humans because of its high fucoxanthin(Fx)content.However,multi-omics analysis of the regula-tory networks for Fx biosynthesis in I.galbana has not been reported.In this study,we report a high-quality genome assembly of I.galbana LG007,which has a genome size of 92.73 Mb,with a contig N50 of 6.99 Mb and 14,900 protein-coding genes.Phylogenetic analysis confirmed the monophyly of Haptophyta,with I.galbana sister to Emiliania huxleyi and Chrysochromulina tobinii.Evolutionary analysis revealed an estimated divergence time between I.galbana and E.huxleyi of～133 million years ago.Gene family analysis indicated that lipid metabolism-related genes exhibited significant expansion,including IgPLMT,IgOAR1,and IgDEGS1.Metabolome analysis showed that the content of carotenoids in I.galbana cultured under green light for 7 days was higher than that under white light,and β-carotene was the main carotenoid,accounting for 79.09％of the total carotenoids.Comprehensive multi-omics analysis revealed that the content of β-carotene,antheraxanthin,zeaxanthin,and Fx was increased by green light induction,which was significantly correlated with the expression of IgMYB98,IgZDS,IgPDS,IgLHCX2,IgZEP,IgLCYb,and IgNSY.These findings contribute to the understanding of Fx biosynthesis and its regulation,pro-viding a valuable reference for food and pharmaceutical applications.

Objective:To investigate whether idebenone can improve behavioral disorders in mice with Parkinson disease (PD) by increasing PHB2 mediated mitophagy.Methods:In the first small experiment, thirty mice were randomly divided into normal control group, model group and treatment group according to the random number table method, with 10 animals in each group.The aim of this study was to observe the effect of idebenone on the behavior of Parkinson disease model mice. In the second experiment, 20 mice were randomly divided into blank control group, MPTP group, shRNA-PHB2 group and shRNA-PHB2+ MPTP group, with 5 mice in each group. The changes of tyrosine dehydrogenase (TH) in brain tissue were detected by immunofluorescence assay. In the third experiment, 30 mice were randomly divided into blank control group, shRNA-PHB2 group, MPTP+ idebenone group, shRNA-PHB2+ MPTP group, shRNA-PHB2+ idebenone group and shRNA-PHB2+ MPTP+ idebenone group, with 5 animals in each group. The aim of this study was to investigate the effect of idebenone on mitochondrial autophagy in mouse brain.C57BL-6 mice were intraperitoneally injected with MPTP to establish the animal model of chronic PD. Then 200 mg / kg idebenone was given by gavage for 21 days. And the expression of PHB2 in brain was inhibited by microinjection of adeno-associated virus 9 (AAV9) shRNA inhibin 2(PHB2) into lateral ventricle. The behavioral changes of the PD mice were detected by Morris water maze, and the changes of tyrosine dehydrogenase (TH) induced by inhibiting PHB2 were detected by immunohistochemistry. The protein expression of LC3 and PHB2 in substantia nigra of midbrain was detected by Western blot.The data were analyzed by GraphPad 7.0 and SPSS 22.0.Results:(1) In the water maze test data of the first small experiment, the repeated measurement ANOVA showed that the group-time interaction effects of latency of mice from 1 to 7 days were significant ( Ftime×group=20.51, P<0.05). Simple effect analysis showed that on the 5th, 6th and 7th day, the incubation period of the treatment group was significantly shortened (all P<0.05). Univariate analysis of variance showed that on the 7th day of the test, the differences between the control group and the model group, the model group and the treatment group, the control group and the treatment group were all statistically significant( t=-49.95, -21.81, 28.14; all P<0.01). In the third small experiment, repeated measurement analysis of variance showed that the interaction between time and group was significant ( Ftime×group=42.11, P<0.01). Simple effect analysis showed that compared with MPTP+ idebenone group, the latency of shRNA-PHB2+ MPTP+ idebenone group was significantly prolonged (all P<0.05). There were no significant difference between shRNA-PHB2+ MPTP+ idebenone group and shRNA-PHB2+ MPTP group except the 4th day ( P<0.05). On the 7th day, compared with MPTP+ idebenone group, the residence time of shRNA-PHB2+ MPTP+ idebenone group was significantly increased ( t=-34.36, P<0.001), but there was no significant difference between shRNA-PHB2+ MPTP group and shRNA-PHB2+ MPTP+ idebenone group ( t=2.94, P>0.05). (2)The results of immunofluorescence experiment showed that the relative expression of TH in the control group, model group, shRNA-PHB2 group and shRNA-PHB2+ MPTP group were (41.03±3.01), (24.20±4.18), (38.39±3.31) and (13.12±2.65), respectively. Compared with the control group, the expression of TH in the midbrain of the MPTP group was significantly down-regulated, the difference was statistically significant( t=7.98, P<0.01). Compared with the MPTP group, the expression of TH in shRNA-PHB2 group was down regulated ( t=-6.73, P<0.05). (3) Western blot results showed that the relative expression of LC3 in midbrain tissue of control group, shRNA-PHB2 group, MPTP+ idebenone group, shRNA-PHB2+ MPTP group, shRNA-PHB2+ idebenone group and shRNA-PHB2+ MPTP+ idebenone group were (0.86±0.07), (0.77±0.08), (0.42±0.05), (0.21±0.05), (0.66±0.09) and (0.27±0.07). The relative expression of PHB2 were (1.13±0.14), (0.56±0.11), (1.08±0.14), (0.27±0.07), (0.68±0.14) and (0.24±0.10). Compared with MPTP+ idebenone group, the relative expression of LC3 and PHB2 in shRNA-PHB2+ MPTP+ idebenone group was significantly decreased ( F=1.96, P<0.01). Conclusion:Idebenone can increase the level of mitophagy in PD mice through PHB2, thus improving the behavioral disorder.
