Objective To investigate the predictive value of Mayo adhesion probability(MAP)score for intraoperative bleeding during microchannel percutaneous nephrolithotomy(PCNL), so as to provide reference for optimizing surgical decisions.Methods A retrospective analysis was conducted on the clinical data of 86 patients who underwent microchannel PCNL at our hospital during Jan.2018 and Jul. 2025.Patients were divided into two groups based on preoperative CT-derived MAP scores:MAP score＜3 group(n=45)and MAP score≥3 group(n=41).Baseline characteristics, surgical parameters and outcome measures were compared between the two groups.Univariate and multivariate logistic regression analyses were performed to identify risk factors for intraoperative bleeding(defined as a postoperative hemoglobin decrease of ≥20 g/L). Results The incidence of intraoperative bleeding was significantly higher in the MAP score≥3 group than in the MAP score＜3 group(43.9% vs.20.0%, P=0.017).Multivariate analysis identified MAP score ≥3(OR=3.045, 95%CI:1.125-9.547, P=0.019), use of anticoagulant medication(OR=3.016, 95%CI:1.251-9.257, P=0.020), establishment of multiple tracts(OR=5.445, 95%CI:1.798-17.578, P=0.003), and operation time ≥90 minutes(OR=5.697, 95%CI:1.890-13.632, P=0.001)as risk factors for intraoperative bleeding.The area under the curve for the MAP score in predicting intraoperative bleeding was 0.704.Conclusion The MAP score is an independent risk factor for intraoperative bleeding during microchannel PCNL.Preoperative assessment can help identify high-risk patients and provide a basis for optimizing surgical decision-making.

As one of the core pathogenesis during treatment with traditional Chinese medicine，liver heat runs through different stages of liver disease. The interpretation of its meaning in different medicine categories（traditional Chinese medicine，Tibetan medicine，Mongolian medicine，Uygur medicine，Dai medicine，Yao medicine，etc.） is not unified， and the phenomena of the same name with different meanings，confusion， and misappropriation emerge. This seriously restricts the inheritance，innovation， and clinical application of traditional Chinese medicine and ethnomedicine. By tracing and analyzing liver heat， it is found that liver heat in traditional Chinese medicine is caused by disordered rest and diet， as well as internal injury due to emotional disorder， which leads to liver dysfunction， Qi stagnation， and heat turning to fire in the liver meridian. The liver heat in Tibetan medicine is caused by the accumulated heat of the liver nature and the evil heat in the liver， which stimulates the toxin of Chiba fever. The liver heat in Mongolian medicine derives from the abnormal diet and rest， making excessive Sheila accumulate in the liver and causing disease. The above etiologies are all related to diet， rest，exogenous evil，emotion，and so on， and the pathogenesis is related to the imbalance of Qi and the metabolic disorder of organs. The clinical symptoms are pain in the liver region，yellow eyes， bitter mouth， fever，digestion，and loss of appetite. The principle of treatment and compatibility of prescription are heat-based， with auxiliary detoxification. Other ethnomedicine， such as Uygur medicine， Dai medicine， Yao Medicine，Miao medicine， and She medicine do not have a clear discussion on liver heat，and their etiology， pathogenesis， treatment，and prescription are not systematic，mostly based on a single drug or proven prescriptions.Through the systematic tracing，mining，induction，analysis， and arrangement of the liver heat based on existing literature information database in China，this paper regarded syndrome as the outline and disease as the goal，clarified the similarities and differences of the pathogenesis of liver heat in traditional Chinese medicine，and determined the relationship between liver heat and liver disease and the status quo of syndrome and treatment.This review provides evidence and reference for clinical prevention and treatment，as well as drug development for liver disease.

Objective To evaluate the application effect of perioperative cluster nursing interventions in patients under-going robot-assisted radical prostatectomy.Methods A total of 122 prostate cancer patients who underwent robot-assisted sur-gery from January 2023 to December 2024 were divided into the control group(routine care,55 cases)and the observation group(cluster nursing,67 cases)according to the nursing methods.The psychological status,surgery-related indicators,postoperative recovery,incidence of perioperative complications,and patient satisfaction were compared between the two groups.Results The observation group demonstrated a statistically significant decrease in postoperative anxiety and depression scores compared to the control group(P=0.034,P=0.005).The observation group exhibited shorter operative time and less intraoperative blood loss,with both differences being statistically significant(P=0.016,P＜0.001).In terms of postoperative recovery,the obser-vation group showed faster recovery of bowel function,shorter time for catheter insertion and postoperative hospital stay compared to the control group(P=0.010,P＜0.001,P＜0.001).In the observation group,the incidence of systemic postoperative in-fection was lower than that of the control group(4.5％vs 18.2％,P=0.015).The perioperative hypothermia rate in the obser-vation group was lower than that of the control group(38.8％vs 60.0％,P=0.020).There was no statistically significant difference in postoperative urinary fistula rate between the two groups(P=0.477).The observation group achieved an overall patient satisfaction rate of 98.51％,with higher satisfaction scores compared to the control group(P=0.008).Conclusion Perioperative cluster nursing measures yield favorable outcomes in patients undergoing robot-assisted radical prostatectomy.It can not only shorten the operation time,promote the postoperative recovery of patients,but also reduce the anxiety and depression of patients and complica-tions,and improve patient satisfaction.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

With the development of precision medicine and molecular pathology, fluorescence in situ hybridization (FISH) technology has been widely promoted and applied in department of pathology. In FISH detection, the most commonly used probes are HER2 amplification probes and a variety of separation probes. When detecting pathological specimens using separation probes, some specimens may show atypical signals other than the typical red-green separation signals. The observation, understanding and interpretation of atypical signals may affect the results of FISH, which are related to molecular subtyping and drug treatment of the patient. Eight types of atypical signals of separation probes in FISH detection based on reading experience were summarized and analyzed. At the same time, this article provides evidence and analysis on whether the gene has been rearrangedthrough verification experiments, image analysis and experimental analysis in literature, aiming to enhance the understanding of readers to atypical signals of FISH separation probes.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P＞0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P＜0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective:To evaluate the clinical efficacy and safety of an antioxidant gel containing tea polyphenols combined with narrow-band ultraviolet B in the treatment of vitiligo.Methods:A single-center, randomized controlled clinical trial was conducted. From April 25 to June 27, 2024, patients with vitiligo were selected from the Department of Dermatology, Hangzhou Third People's Hospital. An open-label and researcher-blinded design was used. The patients were divided into 3 groups: a phototherapy group receiving phototherapy alone, a tea polyphenols combined group treated with an antioxidant gel containing tea polyphenols combined with phototherapy, and a positive control group treated with an antioxidant gel containing superoxide dismutase combined with phototherapy, with the treatment duration being 3 months. The efficacy was evaluated using the Vitiligo Area Scoring Index (VASI), and when the VASI was improved by ≥ 10%, the treatment would be considered effective. Changes in skin aging and skin barrier function indicators before and after treatment were assessed for 72 vitiligo lesions in the tea polyphenols combined group and for 72 lesions in the phototherapy group. Comparisons between the groups were performed using one-way analysis of variance, Fisher's exact test, chi-square test, or t test. Results:A total of 171 vitiligo patients with 307 target lesions were successfully followed up in this study, including 74 males and 97 females, and their ages ranged from 1 to 64 years. Among the 307 lesions, 95 were treated with phototherapy alone, of which 35 showed improvement, resulting in a total response rate of 36.8% and an average VASI improvement rate of 10.9%; adverse reactions occurred in 29 lesions (30.5%). Of 138 lesions treated with the antioxidant gel containing tea polyphenols combined with phototherapy, 73 showed improvement, resulting in a total response rate of 52.9% and an average VASI improvement rate of 24.0%; adverse reactions occurred in 10 lesions (7.2%). In the positive control group, 74 lesions were treated, and 40 showed improvement, resulting in a total response rate of 54.1% and an average VASI improvement rate of 18.3%; adverse reactions occurred in 5 lesions (6.8%). Compared with the phototherapy group, the tea polyphenols combined group showed a significantly increased total response rate and a VASI improvement rate (both P < 0.01), but a significantly decreased incidence rate of adverse reactions ( P < 0.001). No significant differences in the above indicators were observed between the tea polyphenols combined group and the positive control group (all P > 0.05). In addition, the changes in skin barrier function and skin aging indicators (except for wrinkle depth) before and after treatment were significantly reduced in the tea polyphenols combined group compared to the phototherapy group (all P < 0.05). After the phototherapy alone, the transepidermal water loss significantly increased ( P = 0.004), and the water content of the stratum corneum significantly decreased ( P = 0.012). However, no significant differences in skin barrier function or skin aging indicators were found between pre- and post-treatment in the tea polyphenols combined group ( P > 0.05) . Conclusion:The antioxidant gel containing tea polyphenols could effectively improve the efficacy of narrow-band ultraviolet B in the treatment of vitiligo, and alleviate skin aging and barrier damage caused by phototherapy.

This study evaluates the safety and early clinical outcomes of a novel 3D-printed titanium alloy "sleeve" component for revising fractured femoral stem prostheses in distal femoral megaprostheses without removing the fractured stem. The six patients included 2 males and 4 females, with an age range of 8-57 years. They were treated at Peking University People's Hospital between August 2020 and December 2023 and underwent revision surgery using the customized sleeve. A self-designed 3D-printed titanium alloy "sleeve" component was used for revision without removing the fractured stem, in the form of an external sleeve around the stem. Postoperative imaging was performed every three months to assess implant stability and bone integration. Functional outcomes were evaluated using the Musculoskeletal Tumor Society (MSTS)-93 score. All six patients successfully completed the surgery and follow-up, with surgical durations ranging from 120 to 230 minutes and intraoperative blood loss ranging from 150 to 800 ml. The follow-up period ranged from 6 to 46 months. At three months postoperatively, X-ray and CT imaging showed cortical bridging between the host bone and the "sleeve" component. By six months, full integration of the host cortical bone with the metal trabecular interface of the "sleeve" was observed. At the final follow-up, MSTS-93 scores ranged from 26 to 29 points, with no complications such as wound healing issues, implant loosening, fracture, infection, or degenerative arthritis. These findings suggest that 3D-printed titanium "sleeve" provide an effective, bone-preserving solution for femoral stem revision in oncologic megaprostheses, leading to favorable early stability and functional recovery.
