Cancer stands as a significant global public health challenge, and cancer screening serves as a pivotal strategy for reducing its mortality. Presently, only a limited number of cancer types have appropriate screening methods available. Traditional single-cancer screening approaches are fraught with limitations, including invasiveness, low accuracy, and poor patient compliance. Multi-cancer early detection (MCED) leveraging liquid biopsy technology enables non-invasive and efficient early detection of multiple cancers by analyzing biomarkers such as cell-free DNA, cell-free RNA, proteins, and metabolites in blood and other bodily fluids. This innovative approach substantially broadens the spectrum of detectable cancers and enhances population coverage, showcasing immense potential for improving existing cancer screening strategies. This expert consensus comprehensively reviews the progress of liquid biopsy-based MCED, biomarker selection and detection technologies, the criteria for cancer type selection, research design and clinical utility evaluation, as well as implementation pathways. The overarching goal of this consensus is to offer scientific guidance for further research and the widespread adoption of MCED, thereby facilitating the continuous optimization of cancer screening strategies.

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:Efficacy and safety of robot-assisted laparoscopic adrenalectomy as a treatment for large adrenal tumors.Three-dimensional(3D) reconstruction can effectively assist in preoperative planning of robotic adrenalectomy and reduce potential complications.Methods:We retrospectively reviewed the relevant information of patients who had a preoperative 3D reconstruction and underwent RA for adrenal masses larger than 10 cm. Thirteen male patients and sixteen female patients were included. The median(range) age was 43(25, 57) years old and the median tumor diameter was 12.1(10.3, 16.2) cm. The patients underwent preoperative CT enhancement scanning, and three-dimensional images were reconstructed based on the examination data. Robot-assisted laparoscopic adrenalectomy was performed under general anesthesia in 29 cases in this cohort.Results:All surgeries were completed successfully without major complications such as massive bleeding, secondary surgery, or even patient death. The median operative time was 131 (80, 245) min, and the median intraoperative bleeding was 330 (50, 2 200 ml) ml. 9 patients received blood transfusions. There were 11 cases of pheochromocytoma (37.9%), 10 cases of adenocarcinoma (34.5%) as well as 2 cases of teratoma (6.9%) and 6 cases of cortical carcinoma (20.7%). The patients were followed up for a median of 30 months after surgery. Except for 3 cases lost to follow-up and 2 patients with cortical cancer who developed recurrence or metastasis after surgery and died at 16 and 23 months after surgery, respectively, the remaining 24 cases have survived to date.Conclusions:RA is a safe and effective treatment for huge adrenal tumors. The 3D reconstruction could help the preoperative planning of RA and reduce potential complications.

Objective:To investigate the clinical characteristics, diagnosis and treatment of dermatomyositis with kidney neoplasm.Methods:The data of two patients with dermatomyositis complicated with kidney neoplasm in Tongji Hospital from January to February 2022 were retrospectively analyzed. The first case was a 55-year-old female, who was admitted with the chief complaints of recurrent erythema of upper extremities for 2 months and facial erythema for 1 month. Physical examination: erythema can be seen on upper limbs and face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Mi-2 antibody and anti-SSA /Ro-52 antibody were positive. Contrast CT showed nodular uneven enhancement in the right kidney with a size of 50 mm×41 mm. The second case was a 58-year-old female, who was admitted with the chief complaints of kidney occupying for a month. Physical examination: flaky erythema on face, no tenderness or percussion pain in kidney area. Myositis enzyme profile test showed that anti-Ro-52 antibody and anti-MDA5 antibody were positive. Contrast CT showed a significantly uneven enhanced mass with a size of about 50 mm×41 mm on left kidney. Both patients were diagnosed with kidney neoplasm before surgery and underwent laparoscopic partial nephrectomy in Tongji Hospital.Results:Both patients received regular oral prednisone after surgery. The pathological presentation of case 1 was papillary renal cell carcinoma, the facial erythema subsided 1 month after surgery, and there was no tumor recurrence for 13 months. The pathological presentation of case 2 was clear cell renal cell carcinoma, facial erythema subsided 2 weeks after surgery, and there was no tumor recurrence for 12 months.Conclusions:The diagnosis of dermatomyositis should be combined with clinical manifestations and laboratory examination, and the possibility of malignant tumor should be excluded due to the high likelihood of concomitant malignancy. For patients with dermatomyositis with kidney neoplasm, the main treatment is still surgery, and supplemented with glucocorticoid therapy.

Objective:To study the prevalence and distribution of adult thyroid diseases in urban and rural areas of Hebei Province.Methods:A multi-stage stratified cluster sampling method was used to select Renqiu City and Licun Town, Luquan City of Hebei Province as the urban and rural survey sites, respectively. Questionnaire survey, physical examination and thyroid B ultrasound examination were conducted on local permanent residents (≥ 5 years of residencies) over 18 years old. The fasting venous blood sample was collected to determine the serum thyroid function indicaters.Results:A total of 2 650 adults were surveyed, including 1 393 urban residents and 1 257 rural residents (1 357 males and 1 293 females). A total of 435 patients with thyroid diseases were diagnosed, the detection rate was 16.42%. There were seven thyroid diseases, including subclinical hypothyroidism (60.92%, 265/435), Hashimoto's thyroiditis (34.02%, 148/435), hypothyroidism (4.83%, 21/435), simple goiter (3.22%, 14/435), hyperthyroidism (2.53%, 11/435), subclinical hyperthyroidism (2.53%, 11/435), and thyroid cancer (1.84%, 8/435). The detection rates of thyroid diseases in urban and rural areas were 21.18% (295/1 393) and 11.14% (140/1 257), respectively. The detection rates of thyroid diseases in males and females were 11.42% (155/1 357) and 21.66% (280/1 293), respectively. The detection rates of thyroid diseases in 18-< 30, 30-< 40, 40-< 50, 50-< 60 and ≥60 years old were 13.46% (91/676), 14.81% (81/547), 15.42% (89/577), 20.94% (85/406) and 20.05% (89/444), respectively. There were statistically significant differences between different areas, gender and age groups (χ 2 = 48.54, 50.53, 14.68, P < 0.05). Conclusions:The detection rate of subclinical hypothyroidism in adults in urban and rural areas of Hebei Province is relatively high, followed by Hashimoto's thyroiditis. Attention should be paid to the screening, evaluation, and intervention of thyroid function among urban female populations.

In order to evaluate the efficacy and safety of Hexue Mingmu tablets in the treatment of diabetic retinopathy（DR） and retinal vein obstruction（RVO）， and to provide a basis for the clinical treatment of ophthalmic diseases， this paper obtained randomized controlled trials（RCTs） of Hexue Mingmu tablets in the treatment of DR and RVO by searching Chinese and English electronic databases and trial registration platforms（up to September 13， 2022）. The risk of bias in the included studies was assessed using RoB2.0， and Meta-analysis was performed using RevMan5.4. A total of 35 RCTs involving a total sample size of 3 261 patients were included. Meta-analysis results showed that compared with conventional western medical treatment alone， the combination of Hexue Mingmu tablets with conventional western medical treatment improved patients' macular thickness｛mean difference（MD） =-39.83， 95% confidence interval（CI） ［-51.60， -28.06］， P<0.000 01｝， improved corrected visual acuity｛risk ratio（RR）_dichotomous=1.09， 95% CI ［1.00， 1.18］， P=0.04； MD_{continuous variable}=0.15， 95% CI ［0.13， 0.17］， P<0.000 01｝， increased effective rate of fundus symptom improvement（RR=1.26， 95% CI ［1.22， 1.30］， P<0.000 01）， improved hemorheology index｛standard mean difference（SMD）=-1.53， 95% CI ［-2.04， -1.01］， P<0.000 01｝， shortened improvement time of fundus symptoms（MD=-5.53， 95% CI ［-5.96， -5.09］， P<0.000 01）， and there was no significant difference on adverse events between the two groups. The results show that treatment of DR and RVO with Hexue Mingmu tablets may improve the macular thickness and hemorheology index of patients， which can significantly enhance the effect of corrected visual acuity and clinical efficiency， and shorten the time to symptom improvement. However， the original literature is of low quality and the pooled results have some limitations. Subsequent studies should try to use uniform standard assessment criteria and testing methods， focus on the rigor of study design and implementation， and pay attention to the key outcomes of this disease and the clinical safety of medication， so as to provide more reliable evidence to support this kind of clinical problems.
