Lung cancer constitutes the most prevalent and lethal malignant tumor in China. Approximately 85% of lung cancer diagnoses correspond to the non-small cell histological subtype [non-small cell lung cancer (NSCLC)]. Despite surgery being the mainstay for early-stage disease, postoperative recurrence remains high and adjuvant chemotherapy offers limited benefit. In recent years, targeted therapy has demonstrated substantial advantages in driver mutation-positive NSCLC. To this end, the Lung Cancer Medical Education Committee of the Chinese Medical Education Association developed guidelines based on a systematic review of evidence through November 2025, using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach and a modified Delphi method. Focusing on epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK), and addressing ROS proto-oncogene 1 (ROS1), B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation, and mesenchymal-epithelial transition factor (MET) exon 14 (METex14) skipping, the guideline covers molecular testing, neoadjuvant/adjuvant therapy, perioperative strategies, minimal residual disease monitoring, and postoperative surveillance. It defines testing requirements, specifies stage-directed and subtype-specific treatments, and standardizes minimal residual disease monitoring. These recommendations emphasize precision and feasibility to improve survival and quality of life.

Objective To investigate the causes and management strategies for lower limb ischemic necrosis following xenogeneic heterotopic heart transplantation from a multigene-edited pig to a rhesus monkey. Methods A xenogeneic heterotopic heart transplantation was performed on December 16, 2023, at the Institute of Experimental Animals of Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital, using a quintuple-gene-edited pig as the donor and a rhesus monkey as the recipient. On postoperative day (POD) 9, the recipient monkey underwent left lower limb amputation due to ischemic necrosis. Blood samples were collected at various time points after transplantation for analysis of hematologic parameters, liver and renal function, myocardial enzymes, and coagulation profiles. Ultrasound and computed tomography (CT) were used to evaluate anastomotic patency and cardiac structure. Immunological assays, including complement-dependent cytotoxicity (CDC) and IgG/IgM antibody detection, combined with clinical observations, were employed to assess rejection type and therapeutic response. Results The recipient monkey survived for 46 days after transplantation. Echocardiography demonstrated preserved biventricular systolic function in the recipient’s native heart, with left ventricular ejection fraction (LVEF) consistently exceeding 50%. In the donor pig heart, left ventricular endocardial thickening was noted on POD 9, followed by right ventricular endocardial thickening on POD 24, while LVEF remained around 35%. No hyperacute or acute rejection was detected immunologically. CDC positivity ranged between 3.4% and 5.1%, with IgG/IgM antibody binding trends consistent with CDC results. Following amputation, the recipient exhibited elevated inflammatory markers, coagulopathy, and reactive thrombocytosis, which later normalized. Immunohistochemical staining of the necrotic limb revealed arterial and venous thrombosis; however, no T-cell or B-cell infiltration was observed in vascular structures, thrombi, nerves, muscles, fascia, or skin tissues, with CD3 and CD20 staining both negative. Conclusion Limb ischemia after xenogeneic heart transplantation may be associated with lower extremity vascular thrombosis triggered by local trauma in the context of transplantation-induced inflammatory activation and coagulation dysfunction. While no clear lymphocyte-mediated rejection was observed, further studies are needed to explore the potential role of non-lymphocyte-mediated immune mechanisms.

ObjectiveTo explore the coercive experience of involuntarily hospitalized adolescents with mental disorders during the admission process and hospitalization， providing references for formulating targeted nursing interventions. MethodsSemi-structured interviews were conducted with 15 involuntarily hospitalized adolescents with mental disorders selected from October to December 2023， and the themes were summarized and extracted by content analysis. ResultsA total of 3 themes and 10 sub-themes were extracted， which were used to elaborate the essential contents， causes， and improvement methods of coercive experience. These encompassed the multi-dimensional content of coercive experience （complex emotional experience， different physical sensations， and contradictory cognitive evaluation）， the multi-faceted causes of coercive experience （insufficient personal preparation， inadequate parental communication， and strict medical management system）， as well as the phased improvement of coercive experience （adequate communication before hospitalization， patient notification before coercive intervention， respecting for demands during coercive intervention， and comforting explanation after coercive intervention）. ConclusionThe essential content of the coercive experience of involuntarily hospitalized adolescents with mental disorders is complex and has various causes， which require cooperation from multiple parties to improve. Therefore， parents should respect the expression of their children’s self-will， and medical staff should respect patients’ autonomy， establishing a protection-constrained doctor-patient relationship model and collaborating to reduce the use of coercive interventions， to improve the overall medical satisfaction of adolescents with mental disorders.

China is facing the double burden of high incidence of lung cancer and tuberculosis epidemic. Lung cancer combined with tuberculosis has a high incidence and complexity in clinical practice. High-risk groups include immunocompromised people, long-term smokers and people with a history of tuberculosis. The coexistence of the two diseases not only increases the difficulty of diagnosis and treatment decision-making, but also increases the risk of treatment-related adverse reactions and drug interactions. The guideline was developed by Committee of Integrated Rehabilitation for Lung Cancer, Chinese Anti-Cancer Association; Chinese and Western Integrated Lung Cancer Committee of Chinese Anti-Cancer Association; Society of Tuberculosis, Chinese Medical Association, aiming to standardize the diagnosis and treatment of lung cancer complicated with pulmonary tuberculosis. The guideline emphasizes the core position of combined diagnosis of multimodal imaging, etiology and pathology. It is proposed that anti-tuberculosis and anti-tumor treatment should be coordinated under the framework of multidisciplinary team, and drug interactions and timing optimization should be paid attention to. For surgical treatment, minimally invasive resection combined with systematic lymph node dissection is recommended after infection control. Systemic therapy requires individualized risk stratification and dynamic monitoring of efficacy and adverse reactions. Based on evidence-based medicine and Chinese clinical practice, combined with the accessibility of drugs and technologies, this guideline proposes a whole-process management pathway covering screening, diagnosis, treatment and follow-up, in order to improve the prognosis and quality of life of patients.

OBJECTIVE: The self-defined multidisciplinary (endocrinology, vascular surgery, and orthopedics) scoring system (EMO scoring system for short) was designed. The feasibility of the EMO scoring system to guide the proximal tibial transverse transport (TTT) for diabetic foot wounds was preliminarily explored. METHODS: Based on the current commonly used clinical criteria for diabetic foot judgment, expert consensus, guidelines, and related research progress in the treatment of diabetic foot wounds, combined with clinical experience, a set of EMO scoring systems including endocrinology, vascular surgery, and orthopedics was formulated. The criteria for selecting conservative treatment, TTT after baseline improvement, and TTT based on scoring results was proposed. A total of 56 patients with diabetic foot wounds who were admitted between September 2017 and July 2022 and met the selection criteria was taken as the study subjects. Among them, 28 patients were treated with TTT and 28 patients were treated conservatively. The patients were graded according to the EMO scoring system, the corresponding treatment methods were selected, and the actual treatment methods and results of the patients were compared. RESULTS: The EMO scoring system was formed through literature retrieval and clinical experiences. The system included three criteria, namely endocrinology (E), macrovascular disease (M), and orthopedics (O), which were divided into multiple subtypes according to the relevant evaluation items, and finally the diabetic foot wound was divided into 8 types, which correspondingly selected TTT, TTT after baseline improvement, and conservative treatment. All 56 patients were followed up 12 months after treatment. Among them, the wound healing rate of the TTT group was 85.71% (24/28), which was higher than that of the conservative treatment group [53.57% (15/28)]. At 12 week after treatment, CT angiography showed that there were more small blood vessels in the wound and ipsilateral limb in TTT group than in the conservative treatment group. Based on the EMO scoring system, 14 of the 56 patients needed conservative treatment, 29 patients needed TTT, and 13 patients needed TTT after baseline improvement. Compared with the clinical data of the patients, the wound healing rate of the patients judged to be TTT was 75.86% (22/29), of which 21 cases were actually treated with TTT, and the healing rate was 90.48%; 8 patients were treated conservatively, and the healing rate was 37.50%. The wound healing rate of the patients judged to be conservative treatment was 92.86% (13/14), of which 1 case was actually treated with TTT, and the healing rate was 100%; 13 cases were treated conservatively, and the healing rate was 92.31%; 1 case experienced minor amputation. The wound healing rate of the patients judged to TTT after baseline improvement was only 30.77% (4/13), of which 6 cases were actually treated with TTT, and the healing rate was 66.67%; 7 cases were treated conservatively, and the healing rate was 0. CONCLUSION EMO scoring system can comprehensively evaluate the diabetic foot wounds, and make personalized judgment on whether TTT treatment is feasible, so as to improve the level of diabetic foot wound treatment and the prognosis of patients.

OBJECTIVE: To explore clinical effective and safety of subarachnoid block (SA), adductor canal block (ACB), and femoral nerve block (FNB) for early analgesia in anterior cruciate ligament (ACL) reconstruction. METHODS: From September 2022 to October 2023, 90 patients with ACL rupture who received unilateral knee arthroscopic ACL reconstruction were selected and divided into ACB group, FNB group and SA group according to different anesthesia methods, with 30 patients in each group. There were 12 males and 18 females in ACB group, aged from 18 to 60 years old with an average of (33.3±13.8) years old;14 patients with gradeⅠand 16 patients with gradeⅡaccording to American Society of Aneshesiologists (ASA);13 patients on the left side and 17 patients on the right side. There were 15 males and 15 females in FNB group, aged from 18 to 60 years old with an average of (33.5±12.9) years old;15 patients with gradeⅠand 15 patients with gradeⅡ;16 patients on the left side and 14 patients on the right side. There were 16 males and 14 females in SA group, aged from 18 to 60 years old with an average of (31.0±12.6) years old;18 patients with grade I and 12 patients with gradeⅡ;17 patients on the left side and 13 patients on the right side. In ACB and FNB groups, the nerve block of ACB and FNB were performed under ultrasound guidance before SA anesthesia with 15 ml of 0.3% ropivacaine. Visual analogue scale (VAS) and quadriceps muscle strength at rest and passive movement were recorded and compared among 3 groups at 4, 8, 12, 16, 24 and 48 h after operation, as well as the dosage of tramadol injection analgesics, incidence of nausea and vomiting, nerve block time and other complications within 48 h after operation were compared. RESULTS: All patients were followed up for 11 to 20 (15.8±2.4) months. VAS at 4, 8, 12, 16, 24 and 48 h after operation of SA group was significantly higher than that of ACB and FNB groups, with statistical significance (P<0.05). There were no significant difference in VAS of rest and passive movement at 4, 8, 12, 16, 24 and 48 h after operation between ACB group and FNB group(P>0.05). At 4, 8, 12 and 16 h after operation, the quadriceps muscle strength in SA and ACB groups was higher than that in FNB group, with statistical significance (P<0.05);but there was no statistical significance in quadriceps muscle strength among three groups at 24 and 48 h after operation(P>0.05). One patient occurred nausea and vomiting in ACB group, 2 patients in FNB group and 5 patients in SA group, and no significant difference among three groups (χ²=0.352, P=0.171). The dosage of tramadol in SA group was (300.00±136.50) mg, which was higher than that in FNB group (168.33±73.70) mg and ACB(163.33±70.70) mg, and the difference was statistically significant (P<0.05). There was no significant difference in nerve block time between ACB group and FNB group (t=1.964, P=0.054). There was no puncture site bleeding, local anesthesia drug poisoning and hematoma formation among three groups. CONCLUSION Both FNB and ACB could provide good early analgesia after ACL reconstruction, but ACB group has little effect on quadriceps muscle strength. Patients could have early postoperative functional training without pain, which is more beneficial to the recovery of knee joint function, and could reduce the use of analgesic drugs, without serious complications, which is safe and reliable method.

The aim of this investigation was to determine the optimal storage medium for testicular hypothermic transportation and identify the ideal concentration for the application of the protective agent 5-aminolevulinic acid (5-ALA). Furthermore, this study aimed to explore the underlying mechanism of the protective effects of 5-ALA. First, we collected and stored mouse testicular fragments in different media, including Hank's balanced salt solution (HBSS; n = 5), Dulbecco's Modified Eagle Medium/Nutrient Mixture F-12 (DMEM/F12; n = 5), and alpha-minimum essential medium (αMEM; n = 5). Storage of testicular tissue in HBSS preserved the integrity of testicular morphology better than that in the DMEM/F12 group ( P < 0.05) and the αMEM group ( P < 0.01). Testicular fragments were subsequently placed in HBSS with various concentrations of 5-ALA (0 [control], 1 mmol l -1 , 2 mmol l -1 , and 5 mmol l -1 ) to determine the most effective concentration of 5-ALA. The 2 mmol l -1 5-ALA group ( n = 3) presented the highest positive rate of spermatogonial stem cells compared with those in the control, 1 mmol l -1 , and 5 mmol l -1 5-ALA groups. Finally, the tissue fragments were preserved in HBSS with control ( n = 3) and 2 mmol l -1 5-ALA ( n = 3) under low-temperature conditions. A comparative analysis was performed against fresh testes ( n = 3) to elucidate the underlying mechanism of 5-ALA. Gene set enrichment analysis (GSEA) for WikiPathways revealed that the p38 mitogen-activated protein kinase (MAPK) signaling pathway was downregulated in the 2 mmol l -1 5-ALA group compared with that in the control group (normalized enrichment score [NES] = -1.57, false discovery rate [FDR] = 0.229, and P = 0.019). In conclusion, these data suggest that using 2 mmol l -1 5-ALA in HBSS effectively protected the viability of spermatogonial stem cells upon hypothermic transportation.
