This paper systematically reviewed the concept of authentication studies on traditional Chinese medicine （TCM） classics and the research achievements of scholars across historical and contemporary periods. We categorized the authentication studies on TCM classics into four types， including work-oriented authentication research， metho-dological studies on authentication， extended authentication research， and single-book authentication. Multiple methods were applied comprehensively， including investigating bibliographic documents of successive dynasties， analyzing the academic contents of medical books， studying the textual characteristics of medical books， examining the cited references in medical books， verifying the biographies of authors， and analyzing the interpolations and accretions in medical books， to distinguish the authenticity of TCM classics. The academic value of authenticity identification of TCM classics is concluded in three aspects，i.e. it serves as an important means to distinguish authenticity from falsehood in TCM classics， an important guarantee for inheriting the essence of TCM literature， and a key to unlocking the academic treasure trove of TCM classics and achieving inheritance-based innovation， which will lay a solid documentary foundation for constructing identification methodologies and standardized systems.

Objective To investigate the relationship between the expression of nuclear factor ⅠB(NFⅠB)in myeloid cells and intestinal inflammation by constructing NFⅠB conditional gene knockout(cKO)mice.Methods Human Protein Atlas database,Genotype-Tissue Expression database,and FANTOM5 database were used to investigate the expression of NFⅠB in inflammatory cells.NFⅠB-floxed mice were constructed using CRISPR/Cas9 technology and hybridized with LyZ2-Cre transgenic mice.Myeloid specific NFⅠB cKO mice(NFⅠBfl/flLyz2-Cre)were obtained by self-crossing the progeny.After the genotype identification of mice by agarose gel electrophoresis,4 NFⅠB cKO mice of C57BL/6N strain were selected as experimental group,and 4 non-cKO mice were selected as control group.Both groups were induced with 2.5％dextran sulfate sodium salt(DSS)under the same condition to establish a chronic colitis model,and the severity of colitis was evaluated by clinical manifestations and histopathology.Results Analysis showed that NFⅠB was expressed in both myeloid granulocytes and monocytes,and the highest expression was found in neutrophils.NFⅠB cKO mice were successfully constructed using CRISPR/Cas9 technology and Cre-loxP system.DSS-induced enteritis NFⅠB cKO mice developed diarrhea,gross blood stools,reduced activity,and weight loss in a short time.The gross examination of the intestines showed that the colon of the NFⅠB cKO mice was significantly shorter than that of the non-cKO mice([8.23±0.35]cm vs[10.30±0.36]cm,P＜0.01).Intestinal H-E staining showed changes in mucosal glandular structure and connective tissue hyperplasia with extensive inflammatory cell infiltration in NFⅠB cKO mice.The histological score of NFⅠB cKO mice was significantly higher than that of non-cKO mice(4.25±0.50 vs 0.50±0.58,P＜0.01).Intestinal immunohistochemical staining showed that more CD11b positive cells were recruited in NFⅠB cKO mice than non-cKO mice.Conclusion Myeloid specific NFⅠB cKO mice have been successfully constructed,and NFⅠB in myeloid cells can reduce infiltration of immune cells(granulocytes or/and monocytes)to inhibit intestinal inflammation.

Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To investigate the effect of phosphorus-containing replacement solution for the prevention and treatment of hypophosphatemia during continuous renal replacement therapy (CRRT) in critically ill patients with blood phosphorus level ≤1.45 mmol/L, and to provide clinical reference.Methods:It was a historical prospective cohort study. The critically ill patients receiving CRRT with blood phosphorus ≤ 1.45 mmol/L in the intensive care unit of Henan Provincial People's Hospital from October 2021 to January 2023 and from April 2023 to January 2024 was selected as the study subjects. The patients were divided into test group (from April 2023 to January 2024) and control group (from October 2021 to January 2023) according to whether phosphate (1.0 mmol/L) was added to the replacement solution during CRRT, and the differences of clinical data before and after CRRT between the two groups were compared. The patients were divided into hypophosphatemia group and non-hypophosphatemia group according to whether blood phosphorus < 0.81 mmol/L within 24 h after the end of CRRT, and the differences of clinical data between the two groups were compared. Logistic regression analysis was used to analyze the related factors of hypophosphatemia.Results:A total of 149 critically ill patients with blood phosphorus level ≤1.45 mmol/L undergoing CRRT were enrolled in the study, with age of 64(47, 75) years and 87 males (58.4%). Among 149 patients, 84(56.4%) had hypophosphatemia after CRRT, and no hyperphosphatemia occurred. The incidence of hypophosphatemia in test group and control group was 40.0% (30/75) and 73.0% (54/74), respectively. There was no statistically significant difference in baseline clinical data before CRRT between test group and control group (all P>0.05). C-reactive protein ( Z=-3.356, P=0.001), blood calcium ( Z=-3.835, P<0.001) and proportion of hypophosphatemia ( χ2=16.467, P<0.001) in the test group were lower than those in the control group, and blood phosphorus ( Z=3.886, P<0.001) in the test group was higher than that in the control group within 24 h after CRRT. Compared with non-hypophosphatemia group, the proportion of parenteral nutrition ( χ2=6.802, P=0.009) and blood calcium within 24 h after CRRT ( Z=-2.515, P=0.012) in the hypophosphatemia group were higher, and blood phosphorus within 24 h after CRRT ( Z=-10.451, P<0.001), blood phosphorus after 24 h after CRRT treatment ( Z=-5.331, P<0.001) and the proportion of applied replacement solution containing phosphorus ( χ2=16.467, P<0.001) in the hypophosphatemia group were lower. The results of multivariate logistic regression analysis showed that parenteral nutrition ( OR=2.521, 95% CI 1.228-5.175, P=0.012) and application of phosphorus- containing replacement solution ( OR=0.241, 95% CI 0.119-0.491, P<0.001) were independent relevant factors of hypophosphatemia after CRRT in the whole cohort of patients. Conclusions:The application of phosphorus-containing replacement solution in critically ill patients with blood phosphorus level ≤1.45 mmol/L undergoing CRRT is safe and effective, and the incidence of hypophosphatemia is low. Application of phosphorus-containing replacement solution in critically ill patients with blood phosphorus level ≤1.45 mmol/L undergoing CRRT can reduce the incidence risk of hypophosphatemia after CRRT.

Objective:To design a novel model for experiments on in vitro irradiation with radioactive seeds using a treatment planning system (TPS) and 3D printing technology and to preliminarily validate the design scientific rigor of the model via experiments on isodose brachytherapy (BT) and external beam radiotherapy (EBRT) on glioma cells in mice. Methods:The TPS was employed to design the model′s shape and calculate the number and positions of radioactive seeds, and 3D printing technology was utilized to fabricate the experimental model. The GL261 cell line was selected for in vitro irradiation experiments, with the mice divided into the control, EBRT, and BT groups. Mice in the EBRT and BT groups were treated with EBRT and BT, respectively, at doses of 2, 4, and 6 Gy. Then, changes in their cell viability, proliferation, and the level of intracellular reactive oxygen species (ROS) were assessed. Results:The model for in vitro irradiation with radioactive seeds was successfully designed and fabricated. The single photon emission computed tomography (SPECT) verified a uniform radioactive distribution within the model, with no significant cold spots. The BT and EBRT groups displayed decreased cell viability with an increase in the radiation dose. Compared to the EBRT group, the BT group exhibited significantly reduced cell viability (51.33% vs. 22.00%, t = 10.94, P < 0.05) and clone counts (172.67 ± 13.11 vs. 53.67 ± 10.22, t = 8.73, P < 0.05), but a significantly increased level of ROS (102.52 ± 6.87 vs. 144.81 ± 6.01, t = -5.26, P < 0.05) at a dose of 6 Gy. Conclusions:An effective model of in vitro irradiation with radioactive seeds is designed based on TPS and 3D printing technology. This provides an experimental model tool and target for research on the BT and EBRT mechanisms.

Objective:To employ single-photon emission computed tomography (SPECT)/CT for isodose assignment in 125I brachytherapy, assess the correlation between photon counts and dose values, and develop a clinical γ-ray visualization model for 125I brachytherapy. Methods:125I radioactive seeds were filled into a self-made 3D printed stereotactic template to build a stereotactic model. The model was scanned by SPECT/CT for photon counts at 0.5, 1.0, 1.5, 2.0 cm from the outermost peripheral seeds, and the corresponding dose values were measured using the Treatment Planning System (TPS). The fitting curve for the photon counts and the dose values was plotted using SPSS 27.0 software. Results:The photon counts of γ rays at distances of 0.5, 1.0, 1.5, and 2.0 cm from the peripheral particles were 7 603.57±1 806.35, 4 018.26±1 315.72, 2 074.04±791.53, and 1 080.34±424.79, respectively, showing a significant difference ( F=743.72, P<0.01). The dose values (in Gy) in the TPS at distances of 0.5, 1.0, 1.5, and 2.0 cm from the peripheral particles were 208.05±37.57, 125.43±17.74, 86.76±17.67, and 61.55±14.39, respectively, which were significantly different ( F=930.46, P<0.01). The photon counts were linearly correlated with the dose values ( y=0.02 x+ 46.45, R2=81.2%, P<0.01). Conclusions:SPECT/CT-based γ-ray photon count detection can be used to assign doses for 125I brachytherapy, enabling the visualization of γ rays in 125I brachytherapy. This approach has a distinct advantage over TPS, laying the foundation for the establishment of an alternative system to TPS.

The construction,renovation,and expansion of general hospitals involve numerous infection control issues,including zoning,flow line design,and air flow direction.Although relevant regulations have specified infection control require-ments for hospital architectural design,infection control professionals often struggle to provide planning and design recommenda-tions from a professional perspective due to the lack of integrated guidelines.Based on this,this article summarizes the standards and key issues that should be considered during the planning and design of critical departments in general hospitals,aiming to provide reference for infection control professionals.

Objective:To observe the correlation between the level of advanced glycosylation end products (AGE) in skin and diabetic retinopathy (DR), and establish and preliminatively verify the nomogramolumbaric model for predicting the risk of DR.Methods:A clinical case-control study. A total of 346 patients with type 2 diabetes mellitus (T2DM) who were admitted to the Department of Endocrinology and Ophthalmology of the First Affiliated Hospital of Zhengzhou University from January 2023 to June 2024 were included in the study. Among them, 198 were males and 148 were females. The mean age was (54.77±10.92). According to whether the patients were accompanied by DR, the patients were divided into the non-DR group (NDR group) and the DR group (DR group), 174 and 172 cases, respectively. All patients underwent skin AGE detection using a noninvasive diabetes detector. Diabetes duration, hemoglobin A1c (HbA1c), fasting plasma glucose, Urea, creatinine (Crea), uric acid, total cholesterol, triglyceride, estimated glomerular filtration rate (eGFR), urinary albumin concentration (UALB), and body mass index (BMI) were collected in detail. Univariate analysis and multivariate logistic regression analysis were used to determine the independent risk factors for T2DM concurrent DR, and to construct a nomogram prediction model for DR risk. Receiver operating characteristic curve (ROC curve), calibration curve and decision curve (DCA) were used to evaluate the model.Results:Hypertension prevalence rate ( χ2=3.892), Diabetes duration ( Z=?7.708), BMI ( Z=?2.627), HbA1c ( Z=?4.484), Urea ( Z=?4.620), Crea ( Z=?3.526), UALB ( Z=?6.999), AGE ( Z=?8.097) in DR group were significantly higher than those in NDR group, with statistical significance ( P<0.05); eGFR was lower than that in NDR group, the difference was statistically significant ( Z=?6.061, P<0.05). Logistic regression analysis showed that AGE, diabetes duration, HbA1c, UALB and eGFR were independent risk factors for DR ( P<0.05). Based on the results of multi-factor regression analysis, a nomogram prediction model was constructed. The area under ROC curve of the model was 0.843, 95% confidence interval was 0.802-0.884, sensitivity and specificity were 79.1% and 75.9%, respectively. The calibration curve was basically consistent with the ideal curve. The results of DCA analysis showed that when the model predicted the risk threshold of patients with DR between 0.17 and 0.99, the clinical net benefit provided by the nomogram model was> 0. Conclusions:Skin AGE level is an independent risk factor for DR. The nomogram prediction model based on AGE, diabetes duration, HbA1c, eGFR and UALB can accurately predict the risk of DR, and has good clinical practicability.

Objective:To evaluate the safety and feasibility of double-port laparoscopic cholecystectomy (LC) combined with transcystic common bile duct (CBD) exploration using ultrafine choledochoscopy on patients with gallbladder stones and common bile duct stones.Methods:Clinical data of 35 patients undergoing double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy in Anhui No.2 Provincial People’s Hospital from December 2021 to June 2024 were retrospectively analyzed, including 8 males and 27 females, aged (45.8±18.1) years. In all patients, the diameter of the gallbladder duct was greater than 3 mm, the maximum diameter of the stones was less than 10 mm, and the number of stones was less than 5, and the gallbladder ducts were normal. Magnetic resonance cholangiopancreatography (MRCP) was used to measure the diameter of CBD, the number and the maximum diameter of stones. The operative time, intraoperative blood loss, postoperative anal exhaust time, postoperative hospital stay and complications (including abdominal infection, biliary tract infection, bile leakage, bleeding, etc.) of all patients were analyzed. The incidence of bile duct stenosis, residual stone or stone recurrence were followed up by telephone or outpatient review.Results:MRCP measurement indicated that the common bile duct diameter of patients was (8.1±1.3) mm. Single CBD stone occurred in 27 cases (77.1%, 27/35), and the mean maximum diameter of CBD stones was (3.9±1.3) mm. All patients successfully underwent the procedure. The operative time was (80.1±10.9) min, the intraoperative blood loss was (25.5±10.2) ml, the recovery time of postoperative anal exhaust was (17.3±4.7) h, and the postoperative hospital stay was (2.5±0.6) d. There were no complications such as abdominal and biliary tract infection, bile leakage and bleeding. All patients were followed up for 1-30 months, with a median follow-up time of 12 months. No biliary stricture, residual stones or recurrence occured during the follow-ups.Conclusion:In selected cases, double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy could be safe and feasible, with less trauma, quick recovery and short operative time.
