Objective To evaluate the overall implementation of the WS 76-2020 standard in Anhui Province, China and identify and analyze the factors affecting the implementation of the standard, and to provide a basis for the effective implementation and revision of WS 76-2020. Methods According to the requirements of the Notice of the Department of Regulations in National Health Commission on the 2024 assessment of implementation of mandatory standards, an evaluation of radiological health standards was organized and conducted in Anhui Province. The evaluation involved the three dimensions of standard implementation status, technical content of the standards, and effectiveness of standard implementation, with subsequent data analysis. Results The total evaluation score for WS 76-2020 was 87.83 points, indicating that the standard effectively guided the quality control testing of medical X-ray diagnostic equipment. However, stability testing was either underutilized or not performed in practice. The qualified rate of X-ray diagnostic equipment in the province was 94.26%, with equipment performance issues identified as the leading contributor to non-qualified instances. Expert discussions highlighted recommendations particularly concerning the operability, applicability, and scientific rigor of the standard. Conclusion It is recommended to strengthen the dissemination and training for the standard, promote medical institutions to voluntarily conduct stability testing, provide supplementary clarifications or revisions for problematic clauses, and standardize quality control testing techniques for radiological diagnostic equipment.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To summarize the clinical experience of the treatment for complex aortic coarctation with extra anatomic bypass and anatomic correction techniques. Methods The clinical data of patients with complex aortic coarctation treated in the First Affiliated Hospital of Nanjing Medical University and Friendship Hospital of Ili Kazakh Autonomous Prefecture between April 2012 and November 2020 were retrospectively reviewed. Results A total of 12 patients were enrolled, including 5 males and 7 females aged 11-54 (34.3±16.2) years. Extra anatomic bypass grafting was performed in 8 patients and anatomic correction was performed in 4 patients. The operations were successful in all patients. There was no perioperative death. The average cardiopulmonary bypass time was 203.0±46.0 min (7 median incision patients), and the average intraoperative blood loss was 665.0±102.0 mL. The average postoperative ventilator support time was 32.3±7.5 h, and the average postoperative hospital stay time was 10.2±4.3 d. The mean drainage volume of median incision was 1 580.0±360.0 mL, and the mean drainage time was 9.3±2.7 d. The mean drainage volume of left thoracotomy was 890.0±235.0 mL, and the mean drainage time was 4.8±2.5 d. One patient had a transient hoarse after operation and recovered 6 months later. The follow-up period ranged from 2 to 10 years with an average time of 81.0±27.0 months. All patients had a recovery of hypertension, cardiac afterload after 2 years postoperatively. One patient who received an artificial blood vessel replacement in situ was examined stenosis recurrence at the third year after discharge. Others were asymptomatic during the follow-up period. There were no death or other complications. Conclusion The treatment strategy for complex aortic coarctation should be individualized according to the anatomical features and concomitant heart diseases. Extra anatomic bypass technique is a safe and feasible choice.

ObjectiveTo investigate the effects of Shegan Mahuangtang and its pungent and bitter Chinese herbs on the expression of transient receptor potential vanilloid-1 (TRPV1) and bitter taste receptor 14 (TAS2R14) in the lung tissue of the rat model of cold asthma. MethodSeventy SD rats were randomized into 7 groups: normal, model, Shegan Mahuangtang, pungent Chinese herbs, bitter Chinese herbs (6.43 g·kg-1), dexamethasone (0.5 g·kg-1), and Guilong Kechuanning (10 g·kg-1). The rat model of cold asthma was established by intraperitoneal injection and subcutaneous injection of 10% ovalbumin (OVA) and aluminium hydroxide in the limbs, combined with 2% OVA atomization and cold (2-4 ℃) stimulation. The rats were treated with corresponding drugs by gavage and atomization, and the normal and model groups were treated with the same amount of normal saline for 3 weeks. After the last excitation, airway inflammation and cell proliferation were observed by hematoxylin-eosin (HE), periodic acid-Schiff (PAS), and Masson staining of the lung tissue. The levels of interleukin-5 (IL-5), tumor necrosis factor-α (TNF-α), thymic stromal lymphopoietin (TSLP), and transforming growth factor-β1 (TGF-β1) in the serum were measured by enzyme-linked immunosorbent assay (ELISA). The expression of TRPV1 and TAS2R14 was detected by immunofluorescence. The expression of TRPV1, TAS2R14, phospholipase Cβ2 (PLCβ2), B-cell lymphoma-2 (Bcl-2), and α-smooth muscle actin (α-SMA) in the lung tissue was determined by Western blot. ResultCompared with the normal group, the model group showed decreased water intake, food intake, and body weight, increased airway inflammatory cell infiltration, goblet cell proliferation, tissue fibrosis and collagen deposition, elevated levels of IL-5, TNF-α, TSLP, and TGF-β1 in the serum (P<0.01), upregulated expression of TRPV1, PLCβ2, and α-SMA, and downregulated expression of TAS2R14 and Bcl-2 (P<0.05, P<0.01). Compared with model group, Shecgan Mahuangtang, pungent Chinese herbs, and bitter Chinese herbs increased the water intake, food intake, and body weight, reduced the inflammatory cell infiltration and goblet cell proliferation, alleviated tissue fibrosis and collagen deposition, lowered the levels of IL-5, TNF-α, TSLP, and TGF-β1 in the serum (P<0.01), downregulated the expression of TRPV1, PLCβ2, and α-SMA, and upregulated the expression of TAS2R14 and Bcl-2 (P<0.05, P<0.01). ConclusionShegan Mahuangtang and its pungent and bitter Chinese herbs can reduce OVA-induced airway inflammation, downregulate the expression of TRPV1, PLCβ2, and α-SMA, and upregulate the expression of TAS2R14 and Bcl-2 in asthmatic rats. Moreover, bitter Chinese herbs outperformed pungent Chinese herbs, and the combination of them enhanced the therapeutic effect. It is suggested that Shegan Mahuangtang and its pungent and bitter Chinese herbs may ameliorate the OVA-induced airway inflammation by inhibiting TRPV1 and activating TAS2R14.

Objective:To explore the uptake characteristics and temporal changes of 68Ga-fibroblast activation protein inhibitors (FAPIs) and 18F-FDG in the anastomotic site of reconstructed digestive tracts after radical surgery for gastrointestinal adenocarcinoma. Methods:A cohort of 43 patients (28 males, 15 females; age range 28-79 years) who underwent radical surgery for gastrointestinal adenocarcinoma and underwent 18F-FDG PET/CT follow-up between November 2020 and June 2022 in the First Affiliated Hospital of the Air Force Medical University was prospectively included. One week after the 18F-FDG PET/CT examination, 68Ga-FAPI-04 PET/CT imaging was performed. ROIs were drawn on the PET images at the highest uptake level of anastomotic sites of reconstructed digestive tract and abdominal wall incisions, and SUV max and target-to-background ratio (TBR) were determined. χ2 test, one-way analysis of variance, Kruskal-Wallis rank sum test (Bonferroni correction) and Wilcoxon signed-rank test were supplied. Results:There were 86 surgical wounds (13 gastric-intestinal anastomotic sites, 14 esophagus-intestinal anastomotic sites, 16 intestinal-intestinal anastomotic sites, and 43 abdominal wall incisions) included. In 68Ga-FAPI-04 PET imaging, SUV max of gastric-intestinal anastomotic sites was higher than that of abdominal wall incisions, with a statistically significant difference (adjusted P=0.014). The TBR did not show statistically significant differences among different types of surgical wounds ( H=3.88, P=0.275). In 18F-FDG PET imaging, SUV max of gastric-intestinal, esophagus-intestinal, and intestinal-intestinal anastomotic sites were all higher than that of abdominal wall incisions, with statistically significant differences (adjusted all P<0.001). There were no statistically significant differences in TBR among different types of surgical wounds ( H=3.02, P=0.388). In 68Ga-FAPI-04 PET imaging, the TBR of all types of anastomotic sites exhibited a decreasing trend with increasing postoperative time. Except for intestinal-intestinal anastomotic sites, the differences in TBR between < 0.5-year and ≥ 1.5-year groups were statistically significant for other types of surgical wounds (adjusted P<0.05). In 18F-FDG PET imaging, the TBR of abdominal wall incisions showed a decreasing trend with increasing postoperative time. However, the TBR of other types of surgical wounds did not show a decreasing trend, and the differences in TBR among different time groups were not statistically significant ( H values: 0.53-2.75, P values: 0.252-0.768). In comparing the two PET imaging agents, for all surgical wounds within the <0.5-year and 0.5-1.5-year groups, the 68Ga-FAPI-04 TBR was consistently higher than the 18F-FDG TBR ( z values: -3.17 and -2.55, P values: 0.002 and 0.011). However, in the ≥1.5-year group, the TBR values tended to be consistent, and the differences were not statistically significant ( z=-0.70, P=0.485). Conclusions:The 18F-FDG uptake in the anastomotic sites of reconstructed digestive tracts reaches a low level under half a year after surgery and does not significantly change over time, while the 68Ga-FAPIs uptake remains relatively high within the first 1.5 years after surgery but decreases over time. These patterns suggest that clinical attention should be paid to the differential diagnosis of anastomotic inflammation or fibrosis, which resulting in agent uptake and local tumor recurrence.

To evaluate the safety and efficacy of neoadjuvant radiohormonal therapy for oligometastatic prostate cancer (OMPC), we conducted a 3 + 3 dose escalation, prospective, phase I/II, single-arm clinical trial (CHiCTR1900025743), in which long-term neoadjuvant androgen deprivation was adopted 1 month before radiotherapy, comprising intensity modulated radiotherapy to the pelvis, and stereotactic body radiation therapy to all extra-pelvic bone metastases for 4-7 weeks, at 39.6, 45, 50.4, and 54 Gy. Robotic-assisted radical prostatectomy was performed after 5-14 weeks. The primary outcome was treatment-related toxicities and adverse events; secondary outcomes were radiological treatment response, positive surgical margin (pSM), postoperative prostate-specific antigen (PSA), pathological down-grading and tumor regression grade, and survival parameters. Twelve patients were recruited from March 2019 to February 2020, aging 66.2 years in average (range, 52-80). Median baseline PSA was 62.0 ng/mL. All underwent RARP successfully without open conversions. Ten patients recorded pathological tumor down-staging (83.3%), and 5 (41.7%) with cN1 recorded negative regional lymph nodes on final pathology. 66.7% (8/12) recorded tumor regression grading (TRG) -I and 25% (3/12) recorded TRG-II. Median follow-up was 16.5 months. Mean radiological progression-free survival (RPFS) was 21.3 months, with 2-year RPFS of 83.3%. In all, neoadjuvant radiohormonal therapy is well tolerated for oligometastatic prostate cancer.
