This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

Objective To analyze the development of nuclear medicine services in Hunan Province and to assess internal radiation doses among the nuclear medicine workers (NMWs) involved in iodine-131 radionuclide therapy. Methods Based on a survey of nuclear medicine institutions in Hunan Province, a total of 61 NMWs from seven hospitals providing iodine-131 therapy for thyroid cancer were selected as the study subjects by convenience sampling method. Thyroidal iodine-131 activity was measured using a portable gamma spectrometer to estimate internal dose and total annual effective dose. Results A total of 47 nuclear medicine institutions were reported in Hunan Province by 2023, most of which were public and tertiary hospitals, accounting for 38. Iodine-131 therapy was performed in 30 institutions, including nine for thyroid cancer. A total of nine participants had detectable thyroidal iodine-131 activity among 61 workers involved in iodine-131 thyroid cancer treatment, with the detection rate of 14.8%. Their internal radiation annual committed effective doses ranged from 0.100 to 1.584 mSv, with a mean of 0.499 mSv and median of 0.426 mSv. Except for one cleaner, the remaining eight physicians and nurses had the total annual effective doses ranging from 0.311 to 3.007 mSv, with a mean of 1.305 mSv, all below the annual dose limit of 20.000 mSv among radiation workers specified in national standard. Conclusion Internal exposure to iodine-131 among the NMWs should not be neglected. Standardized procedures and strengthened internal dose monitoring are recommended.

Objective:To investigate the effect of DExH-box helicase 9(DHX9)O-linked N-acetylglucosamine(O-GlcNAc)modifi-cation(O-GlcNAcylation)on the proliferation of hepatitis B virus(HBV)-associated hepatoma cells.Methods:The pAdTrack-TO4-DHX9-3Flag recombinant adenovirus plasmid was constructed by molecular cloning and transfected into HEK293 cells for packaging and amplification of the recombinant adenovirus AdDHX9.The interaction between DHX9 and O-GlcNAc transferase(OGT)was con-firmed using co-immunoprecipitation.The co-localization between DHX9 and OGT was measured by immunofluorescence.The level of DHX9 O-GlcNAcylation was determined using succinylated wheat germ agglutinin(sWGA)and glycosylated immunoprecipitation(IP).The effect of DHX9 O-GlcNAcylation on the proliferation of HBV-associated hepatoma cells was assessed using the colony-forming assay and cell growth curves.Results:The recombinant adenovirus AdDHX9 was successfully obtained,and DHX9 expression was confirmed by Western blot.DHX9 interacted with OGT,and the two proteins were co-localized on the nucleus.The sWGA and gly-cosylated IP experiments showed that DHX9 underwent O-GlcNAcylation,which was further enhanced by HBV infection.The colony-forming assay demonstrated that the number of cell clones was increased in the AdDHX9 group(386.667±15.630)compared with the AdGFP control group(142.667±7.572,P<0.001).Moreover,cell growth curves demonstrated that the overall cell growth rate was en-hanced in the AdDHX9 group(22.860±0.770)compared with the AdGFP control group(13.670±0.517,P<0.001).Conclusion:HBV infection promotes DHX9 O-GlcNAcylation,which enhances the proliferation of HBV-associated hepatoma cells.

Accurate identification of the glomerular ultrastructure is critical for the diagnosis of chronic kidney diseases,but the high cost of acquiring high-quality annotated data limits the application of fully-supervised learning.Therefore,a multi-class semi-supervised semantic segmentation framework based on segment anything model(MC4S-SAM)is proposed.After improving the mask decoder of segment anything model to enable multi-class semantic segmentation without requiring prompt information,the improved model is used to generate and refine pseudo-labels through a self-training strategy,and multi-level consistency regularization constraints are incorporated to enhance the model's performance.Experimental results show that,in the task of segmenting the glomerular mesangial ultrastructure,MC4S-SAM outperformes the fully-supervised model by 11.72%in mean intersection over union(mIoU)and 11.45%in mean Dice similarity coefficient(mDSC)when the labeled data accountes for 1/16 of the total.When the labeled data proportion is 1/4,the mIoU and mDSC reach 68.91%and 78.73%,respectively,demonstrating its significant potential for aiding the diagnosis of chronic kidney diseases.

Objective:To explore the clinical value of computed tomography-three-dimensional(CT-3D)imaging technique in assessing small airway disease(SAD)in children with asthma.Methods:A total of 104 pediatric patients with suspected SAD,who admitted to our hospital from September 2021 to August 2024,were selected,and they were divided into lesion group(48 cases,with obstruction in small airway)and control group(56 cases,lung function without abnormality)according to the results of test for pulmonary function.Both two groups underwent test for lung function and respiratory biphasic CT scan,and the manifestations of high resolution CT(HRCT)image were observed.The correlation between the SAD and the relative indicators of determining ventilation function of lung,which included maximum mid-expiratory flow(MMEF25-75%),forced expiratory flow at 75%vital capacity(FEF75%),forced expiratory flow at 50%vital capacity(FEF 50%),forced expiratory flow at 25%vital capacity(FEF25%)and forced expiratory volume at the first second(FEV1),was analyzed.Results:The MMEF25-75%,FEF75%,FEF50%,FEF25%and FEV1 in the lesion group were significantly lower than those of the control group(t=8.735,12.757,9.724,13.928,10.303,P＜0.05).The incidences of bronchial wall thickening,air retention,Mosaic sign and bronchiole obstruction of HRCT signs of the lesion group were significantly higher than those of the control group(x2=10.715,6.119,6.330,6.587,P＜0.05).Bronchial wall thickening significantly correlated with MMEF25-75%,FEF75%,FEF50%,FEF25%and FEV1(r=-0.360,-0.379,-0.374,-0.367,-0.268,P＜0.001),respectively,and the correlation between it and FEF75%was extremely strong.Air retention significantly correlated with FEF75%and FEV1(r=-0.249,-0.240,P＜0.05),respectively.The Mosaic sign significantly correlated with MMEF25-75%,FEF75%and FEV1(r=-0.236,-0.245,0.257,P＜0.05),respectively.Bronchial obstruction significantly correlated with MMEF25-75%,FEF75%,FEF50%and FEV1(r=-0.248,-0.271,-0.253,-0.275,P＜0.05),respectively.The incidence of asthma in the lesion group was significantly higher than that in the control group(x2=36.783,P＜0.05).Conclusion:The incidence of bronchiolar wall thickening,air retention,Mosaic sign and bronchiolar obstruction of HRCT signs significantly increase in SAD children.They highly correlated with the indicators of ventilation function of lung,especially FEF75%and FEV1,which can reflect the function of small airway at a certain extent.They have great value for identifying early SAD.The application of CT-3D imaging technique in SAD children has a certain of predictive value for the occurrence of asthma.

To provide scientific guidance and standardization for perioperative clinical nursing practice in patients undergoing percutaneous renal biopsy, relevant evidence on percutaneous renal biopsy nursing care was systematically retrieved and synthesized through an evidence-based approach. After two rounds of Delphi expert consultation and expert panel discussions, expert consensus on perioperative clinical nursing standards for patients undergoing percutaneous renal biopsy (hereinafter referred to as the "Consensus") was developed. The Consensus includes three primary themes: preoperative care, intraoperative care, and postoperative care, encompassing 21 secondary themes. It is characterized by scientific rigor, practical applicability, and comprehensiveness, and serves as a valuable reference and guide for clinical nursing professionals across medical institutions.
