Objective To explore the impact of national volume-based procurement policies on the use of medicines in treatment of benign prostatic hyperplasia （BPH） and provide data support for the rational clinical use of medicines in BPH treatment. Methods Data on the use of BPH treatment medications from 2019 to 2023 were extracted from the Chinese Medicine Economic Information Network （CMEI）, covering 892 hospitals （including 645 tertiary hospitals and 247 secondary hospitals）. The changes in various indicators, including the consumption sum, Defined daily doses （DDDs）, Defined daily dose cost （DDDc）, and the ranking ratio （B/A） of these drugs were analyzed and compared. Results From 2019 to 2023, due to the influence of relevant policies, the overall consumption sums of medicines used in the sample hospitals in BPH treatment showed a trend of decreasing first and then rising steadily. The DDDs showed an overall upward trend, while the DDDc demonstrated a gradual decline. Tamsulosin and finasteride consistently ranked first and second in DDDs. The B/A value for tamsulosin was significantly higher than that of other BPH treatment medications. Conclusion The implementation of national centralized drug volume-based procurement policies and other policies from 2019 to 2023 had effectively reduced the economic burden of patients with benign prostatic hyperplasia. Tamsulosin and finasteride, which had the highest B/A in the two categories of α-blockers and 5α-reductase inhibitors, dominated the market for BPH treatment. The clinical use of BPH treatment medications was relatively rational.

Animal experiments are an essential component of life sciences and medical research. However, the external validity and reliability of individual animal studies are frequently challenged by inherent limitations such as small sample sizes, high design heterogeneity, and poor reproducibility, which impede the effective translation of research findings into clinical practice. Systematic reviews and meta-analysis represent a key methodology for integrating existing evidence and enhancing the robustness of conclusions. Currently, however, the application of systematic reviews and meta-analysis in the field of animal experiments lacks standardized guidelines for their conduct and reporting, resulting in inconsistent quality and, to some extent, diminishing their evidence value. To address this issue, this paper aims to systematically delineate the reporting process for systematic reviews and meta-analysis of animal experiments and to propose a set of standardized recommendations that are both scientific and practical. The article's scope encompasses the entire process, from the preliminary preparatory phase [including formulating the population， intervention， comparison and outcome （PICO） question, assessing feasibility, and protocol pre-registration] to the key writing points for each section of the main report. In the core methods section, the paper elaborates on how to implement literature searches, establish eligibility criteria, perform data extraction, and assess the risk of bias, based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis （PRISMA) statement, in conjunction with relevant guidelines and tools such as Animal Research： Reporting of in Vivo Experiments （ARRIVE) and a risk of bias assessment tool developed by the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE). For the presentation of results, strategies are proposed for clear and transparent display using flow diagrams and tables of characteristics. The discussion section places particular emphasis on how to scientifically interpret pooled effects, thoroughly analyze sources of heterogeneity, evaluate the impact of publication bias, and cautiously discuss the validity and limitations of extrapolating findings from animal studies to clinical settings. Furthermore, this paper recommends adopting the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to comprehensively grade the quality of evidence. Through a modular analysis of the entire reporting process, this paper aims to provide researchers in the field with a clear and practical guide, thereby promoting the standardized development of systematic reviews and meta-analysis of animal experiments and enhancing their application value in scientific decision-making and translational medicine.

ObjectiveTo explore the mechanism of modified Liuwei Dihuangtang in preventing and treating renal injury in diabetic kidney disease （DKD） via the angiotensin-converting enzyme 1 （ACE1）/angiotensin Ⅱ （AngⅡ）/angiotensin Ⅱ type 1 receptor （AT1R） axis. MethodFifty male SD rats were randomized into a normal group （n=8） and a modeling group （n=42）. The rats in the modeling group were fed with a high-sugar and high-fat diet for 6 weeks and intraperitoneally injected with 35 mg·kg^-1 streptozotocin （STZ） to establish the model of DKD. After successful modeling， the rats were randomized into model， traditional Chinese medicine （modified Liuwei Dihuangtang granules 21 g·kg^-1）， western medicine （losartan potassium， 33 mg·kg^-1）， and integrated Chinese and western medicine （losartan potassium 33 mg·kg^-1 combined with modified Liuwei Dihuangtang granules 21 g·kg^-1） groups. The levels of fasting blood glucose （FBG）， urinary protein （Up）， blood urea nitrogen （Bun）， and serum creatinine （SCr） were measured in each group after 8 consecutive weeks of drug intervention. Enzyme-linked immunosorbent assay was employed to determine the serum levels of ACE1， AngⅡ， and AT1R. Western blot was employed to measure the protein levels of ACE1， AngⅡ， and AT1R in the renal tissue. The pathological and morphological changes of the renal tissue were observed after hematoxylin-eosin （HE） staining， Masson staining， and periodic acid Schiff 's （PAS） staining. The fecal samples of rats in each group were collected for 16S rDNA high-throughput sequencing. ResultCompared with the normal group， the model group showed elevated levels of Up， FBG， Bun， SCr， ACE1， AngⅡ， and AT1R （P<0.01）， serious lesions in the renal tissue， up-regulated protein levels of ACE1， AngⅡ， and AT1R （P<0.01）， increased Firmicutes/Bacteroidetes （F/B） ratio， decreased relative abundance of Lactobacillus， and increased relative abundance of Moralella and Bifidobacteria. Compared with the model group， drug intervention lowered the levels of Bun， SCr， ACE1， AngⅡ， and AT1R （P<0.01） and alleviated the pathological changes in the renal tissue. Chinese medicine and integrated Chinese and western medicine lowered the levels of Up and FBG （P<0.01）， and western medicine and integrated Chinese and western medicine down-regulated the protein levels of ACE1， AngⅡ， and AT1R. In addition， Chinese medicine down-regulated the protein levels of AngⅡ （P<0.01） as well as ACE1 and AT1R （P<0.05）. Chinese medicine and integrated Chinese and western medicine decreased the F/B ratio， and western medicine and Chinese medicine increased the relative abundance of Blautia. Chinese medicine and integrated Chinese and western medicine increased the relative abundance of Lactobacillus， Ruminococcus undetermined genera， and Bifidobacteria， decreased the relative abundance of Moralella， and increased the Chao 1 and Ace indexes （P<0.05）. Compared with the western medicine group， the integrated Chinese and western medicine group showed lowered levels of Up （P<0.01）， Bun （P<0.05）， and ACE1 and AT1R （P<0.01）， down-regulated protein levels of ACE1， AngⅡ， and AT1R （P<0.05）， alleviated pathological changes in the renal tissue， increased relative abundance of Bifidobacteria， and increased Chao 1 and Ace indexes （P<0.05）. ConclusionModified Liuwei Dihuangtang combined with losartan potassium can mitigate renal fibrosis by regulating the ACE1/AngⅡ/AT1R axis， increasing the relative abundance of Lactobacillus and Bifidobacterium， reducing the relative abundance of Moralella， improving the richness and evenness of intestinal flora， and alleviating pathological damage in the renal tissue.

Drug-induced liver injury （DILI） has a complex mechanism involving various pathways with a synergistic effect on each other and a causal relationship with each other， among which immune response plays an important role in the pathogenesis of DILI. In the context of genetic background， drug active metabolites， drug-molecule complexes， and danger signal molecules may be used as the trigger factors for immune response in DILI， activating the mechanism of drug antigenic hypersensitivity， P-i hypothesis， and danger signal mechanism in innate immunity. The cascade reaction of innate immunity and adaptive immunity leads to the imbalance of the innate immune tolerance of the liver and thus causes immunoinflammatory injury of liver tissue. This article mainly elaborates on the immunological mechanism of DILI， in order to provide new ideas for the research and development of therapeutic targets for DILI and the methods for avoiding adverse drug reactions.

Clinically,pancreatic cancer is a highly aggressive tumor,and neurotropic growth is an important biological feature of pancreatic cancer.Nerve invasion brings great pain burden to patients,and it seriously affects the quality of life and the will to survive of patients.The"three-step analgesia principle"for the management of cancer pain proposed by World Health Organization(WHO)is a traditional therapeutic regimen for cancer pain.However,because of its obvious toxic side effects,poor efficacy,easy addiction,easy drug resistance,non-standard medication of clinical physicians,etc.,the"three-step analgesia principle"is unable to meet the needs of the patient's condition..In recent years,with the development of interventional technology and the development of extensive clinical trials,the interventional means,which is regarded as the"fourth step"of cancer pain management,has achieved great clinical effect,it includes various therapeutic methods and imaging-guided techniques such as neural destruction(denervation),125I particle implantation,patient-controlled analgesic pump technology,implantation of intrathecal drug infusion system,etc.,and clinical practice has proved that these techniques have significant clinical efficacy and they can provide a convenient,safe and effective treatment method for HCC patients.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To establish a lumbosacral triangle (composed of L 5 transverse process, S 1 superior articular process, sacral ala and iliac crest) classification and to guide L 5S 1 endoscopic surgery. Methods:A total of 647 patients with low back pain who admitted to Tianjin Hospital from January 2016 to October 2018 were retrospectively analyzed, including 315 males and 332 females, aged 42.9±15.1 years (range, 19-74 years). The L 5 transverse process sacral distance (TSD), inter trans-verse process length (ITL), interlaminar width (ILW), interlaminar height (ILH), iliosacral angle (ISA), iliac crest height (IH), intervertebral space height (ISH), intervertebral foramen height (IFH), and intervertebral foramen width (IFW) were measured based on lumbar spine anterior-posterior and lateral radiographs. Spearman correlation analysis and hierarchical cluster analysis were used to establish the lumbosacral triangle classification. A total of 822 patients underwent endoscopic L 5S 1 surgery based on lumbosacral triangle classification guidance and verification in Tianjin Hospital from January 2020 to December 2022, including 421 males and 401 females, aged 45.1±16.7 years (range, 15-79 years). The visual analogue scale (VAS) and Oswestry disability index (ODI) were compared before and after surgery, and the Macnab criteria were used to assess surgical outcomes. Results:Spearman correlation analysis showed positive correlations between IH and ISA ( r=0.75, P<0.001), IFH and IFW ( r=0.60, P<0.001), TSD and IFH ( r=0.53, P<0.001), and TSD and IFW ( r=0.40, P<0.001). There was a negative correlation between TSD and IH ( r=-0.46, P<0.001), TSD and ISA ( r=-0.42, P<0.001), IFW and ISA ( r=-0.41, P<0.001), IFW and IH ( r=-0.50, P<0.001), IFH and IH ( r=-0.42, P<0.001). According to Spearman correlation analysis, hierarchical cluster analysis and receiver operating characteristic curve, lumbosacral angle was divided into three types: Type 1, L5 transverse process overlapped with sacral alar; Type 2, 07 mm. Based on lumbosacral triangle classification, different endoscopic techniques were used at L5S1 in 822 patients, including interlaminar approach single-axis endoscopy, trans-foraminal approach single-axis endoscopy, trans-foraminal fenestration approach mobile microendoscopy and unilateral biportal endoscopy, the VAS and ODI of all the patients decreased than those preoperative in immediate postoperative period, half a year postoperative period and the final follow up, and the difference was statistically significant ( P<0.05). At the last follow-up, the Macnab score was excellent in 278 cases, good in 475 cases, and fair in 69 cases, with an excellent and good rate of 91.6% (753/822). Conclusion:Lumbosacral triangle classification is simple and practical, and can effectively guide L5S1 endoscopic surgery.

Objective:To establish an artificial intelligence-based surgical selection system utilizing deep learning to assist in the decision-making process for lumbar endoscopic surgery.Methods:General data of 1,110 patients who underwent percutaneous transforaminal endoscopic discectomy, 804 patients who underwent percutaneous interlaminar endoscopic discectomy, 923 patients who underwent mobile microendoscopic discectomy and 623 patients who underwent unilateral biportal endoscopic in Tianjin Hospital from January 2018 to June 2023 were included in the study. Clinical outcomes were assessed using the visual analogue scale (VAS) for leg and back pain, the Oswestry disability index (ODI), and MacNab criteria both before surgery and 12 months postoperatively. Using a random number table method, patients were divided into a training dataset (2,768 cases) and a test dataset (692 cases) at a ratio of 4∶1. Patient clinical symptoms, physical signs, and multi-modal imaging data were input into a deep learning model. This model was structured into three main modules: intervertebral disc detection, surgical necessity identification, and surgical recommendation. The final surgical method was determined using a convolutional neural network incorporating U-Net for segmentation and ResNet for classification. The accuracy and recall rates of each module were evaluated using the test dataset.Results:Compared to preoperative values, all patients showed significant improvements at the 12-month postoperative follow-up. For patients who underwent percutaneous transforaminal endoscopic discectomy, percutaneous interlaminar endoscopic discectomy, mobile microendoscopic discectomy, and unilateral biportal endoscopic surgery, the VAS scores for leg pain decreased from 7.69±0.80, 7.82±0.88, 7.62±0.69, and 7.56±1.00 preoperatively to 1.44±1.09, 1.35±0.82, 1.51±1.08, and 1.43±0.91 postoperatively. Similarly, the VAS scores for back pain decreased from 5.73±0.83, 6.17±0.99, 6.11±0.88, and 6.46±0.95 to 0.93±0.75, 1.01±0.67, 1.40±0.72, and 1.27±0.70, respectively. Additionally, the ODI significantly decreased from 39.91%±4.50%, 40.05%±8.05%, 47.08%±9.50%, and 44.43%±4.71% preoperatively to 5.77%±2.22%, 6.05%±2.31%, 8.51%±2.16%, and 9.51%±3.70% postoperatively, with all differences being statistically significant ( P<0.05). The excellent rate according to the MacNab criteria was 93.12% (3,222/3,460). In the deep learning model, the multi-modal data of 2,768 patients were input in the training set for deep learning to form a surgical identification and operation recommendation system, and the preoperative data of 692 patients were input in the test set to compare with the final operation method. In the intervertebral disc location module, the accuracy of location and designation of the five lumbar intervertebral discs was 97.1%(672/692). In the module of intervertebral disc need for surgery, the accuracy was 94.8%(3,280/3,460) and the recall rate was 91.9%(636/692). As for patients, the accuracy rate was 91.9%(636/692). In the operation recommendation module, the accuracy rate of operation recommendation based on intervertebral disc was 89.5%(569/636), and the accuracy rate of surgical recommendation based on patient was 82.2%(569/692). Conclusion:In this study, an artificial intelligent surgical procedures selection system based on deep learning was established, which could effectively integrate relevant data and accurately guide the selection of lumbar endoscopic surgery.
