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 investigate the clinical features and risk factors of infection in patients with heat stroke (HS).Methods:The patients with HS who were admitted to the emergency departments of seven hospitals, including West China Hospital of Sichuan University, the Second Affiliated Hospital of Chengdu Medical College and so on, between July 01, 2020 and September 30, 2022 were retrospectively analyzed. The basic characteristics and laboratory test results of the patients were collected. The patients were divided into infected group and non-infected group according to the etiological results, and the differences in clinical characteristics between the different groups were compared. Multivariate logistic regression was used to screen variables, and the predictive model was established and ROC curve was performed to compare the predictive efficiency with SOFA score.Results:During the study period, a total of 183 patients with HS were included, and 156 patients were finally included for analysis according to the inclusion and exclusion criteria. Among them, 58 cases (37.2%) were in the infected group. The mortality of infected group was significantly higher than that of non-infected group (41.4% vs. 25.5%, P < 0.05). Compared with the patients in non-infected group, the infected gourp serum procalcitonin, direct bilirubin, alanine transaminase (ALT), creatinine, lactate dehydrogenase (LDH), creatine kinase isoenzymes, myoglobin, activated partial thromboplastin time (APTT) and respiratory support ratio at admission were significantly higher and albumin level was lower in infected group (all P < 0.05). Multivariate logistic regression analysis showed that myoglobin, ALT, APTT and respiratory support required at admission were independent risk factors for HS co-infection. A prediction model was constructed based on these four indicators, and the area under ROC curve of the prediction model was 0.846, which was better than SOFA score (0.732, P < 0.05). Conclusions:The prognosis of patients with heat stroke complicated with infection were obviously poor. Myoglobin, ALT, APTT and need for respiratory support at admission are risk factors for HS complicated with infection. The prediction model based on these four indicators is better than SOFA score for the early identification of the HS patients with infection.

Objective To investigate the evaluation and suggestion of the courses of Chinese Medicine for clinical students majoring in medical college. Methods In January 2017, at the end of the Chinese Medicine courses, a total of 35 clinical students of Capital Medical University were investigated through a questionnaire, mainly related to students' understanding of Chinese medicine; evaluation and suggestions for Chinese Medicine education and teaching. Results The majority of students believed that Chinese medicine was safe and effective. The proportion of believing worthing learning that the Chinese medicine accounted for 94.3% (33/35), and who believed Chinese medicine helpful for the clinical work accounted for 82.9% (29/35). However, the proportion of satisfaction with the current teaching method was 60% (21/35). Conclusions Most of the clinical students in this investigation have recognized the role of Chinese medicine, and have shown great interest in studying the course, but they are not satisfied with the current teaching. To improve the teaching quality of Chinese Medicine through the reform should be the direction of teachers' efforts in the future.

Objective To explore the effects of continuous nursing on postoperative urinary incontinence in patients with prostate cancer, so as to provide clinical evidence to improve the quality of postoperative and extended nursing care.Methods A total of 120 patients with prostate cancer underwent radical prostatectomy in the First Affiliated Hospital of Wenzhou Medical University from January 2016 to January 2017, who met the inclusion criteria were recruited in the research. The patients were randomly divided into experimental group and control group by sortition randomization method, with 60 cases in each. The patients in control group were given routine discharge health education, and the experimental group received continuous nursing on the basis of routine discharge nursing. Three months after discharge, the incidence, duration, frequency and quantity of urinary incontinence in the two groups were recorded by the International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF). A self-designed prostate cancer postoperative-related knowledge questionnaire, which evaluated the patients understanding prostate cancer care, was completed by the patients of the two groups. A self-designed satisfaction questionnaire was used to evaluate and compare the satisfaction of the two groups of patients to the quality of nursing.Results The incidence rate and the duration of postoperative urinary continence in the experimental group [16.7％,(4.1±2.8) d] were significantly lower than those in the control group (χ2=9.076,t=-2.630;P<0.05). After 3 months of discharge, the score of related knowledge and the satisfaction of nursing work in the experimental group were both higher than those of the control group, and the differences were statistically significant (P<0.05).Conclusions Continuous nursing care for discharged patients after prostatectomy can enhance patients' knowledge of disease, effectively reduce the incidence of postoperative incontinence, reduce urinary incontinence duration, and improve patients' satisfaction with nursing quality.

Objective To explore the real psychological experience in elderly patients with prostatic cancer after castration and to offer reference for formulating targeted interventions.Methods Totally 15 elderly prostatic cancer patients who received castration and total androgen blockade in the First Affiliated Hospital of Wenzhou Medical University from October 2014 to June 2016 were selected by convenient sampling and interviewed intensively.The data were analyzed by Colaizzi's seven-step method for qualitative studies.Results Totally 3 topics were summarized:the sense of uncertainty in elderly prostatic cancer patients after castration;changes in social adaptation;self-image disorder.Conclusions Various psychological crises,especially depression,are experienced in elderly prostatic cancer patients after castration.Therefore,continuous and extensive support is required for elderly prostatic cancer patients after castration.

Objective To study the clinical char acteristics and outcome of two lymphoma patients mimicking Beh?et's disease. Methods Lymphoma was diagnosed in two patients mimicking Beh?et's disease referred to our Department in 2015. A search on published similar cases in Chinese database and the Pubmed was also performed and then analyzed. Results Eight patients were indentified in this pooled analysis, six of which were non-Hodgkin lymphoma (NHL). All of the eight cases presented with cutaneous lesion, seven cases with fever, seven cases with oral ulceration and six cases with orogenital ulceration, respectively. Ocular involvement was present in four of the eight cases, two were with a positive pathergy test. Among feverish patients, six were moderate or high fever, four were high fever, one was low-grade fever. Neutropenia was found in four patients, and lymphocytoponia in four of five patients with detailed data. All patients fulfilled the 2014 International Criteria for Beh?et's Disease (ICBD) with an average score of (5.8 ±1.5), ranging from 4 to 8. Survival period ranged from one month to 36 months, with an average of 8 months. Conclusion For patients diagnosed as Beh?et's disease are finally diagnosed as lymphoma. For patients with Beh?et's disease present-ation but also present with mediate to high fever, atypical deepseated ulcer, neutropenia or lymphocytoponia, malignancy especially lymphoma should be investigated.

Objective To analyze the clinical features of systemic lupus erythematosus (SLE) com-plicated by noncirrhotic portal hypertention (NCPH),and improve the recognition of NCPH.Methods Clinical data from SLE complicated by NCPH in our hospital were retrospectively analyzed and summarized,while the related literatures were reviewed.Results Four patients diagnosed as SLE complicated by NCPH were all women.NCPH presented with the clinical features of portal hypertension with normal or slightly elevated transaminase.Anticardiolipin (ACL) antibodies were positive in 2 patients.Two patients underwent liver needle biopsy,showing nodular regenerative hyperplasia,of which,one with liver portal fibrosis.The treatment strategy was managing the primary disorder and controling of portal hypertention in four patients.Twenty-two cases of SLE complicated by NCPH were reviewed and analyzed,including 18 cases from related literatures and our 4 cases.Among the 22 cases,the mean time between the diagnosis of SLE and NCPH was eight years,of which one patient with NCPH before SLE,one diagnosed at the same time and the rest with NCPH after SLE.19％ (4/21) of patients presented with Raynaud's phenomenon and 18％ (4/22) complicated by pulmonary hypertension.In serological tests,patients presented with positive ACL anti-bodies [33％(7/21)] and anti-dsDNA [48％(10/21)],as well as increased IgG and γ-Globulin [38％(8/21)].Liver needle biopsy showed nodular regenerative hyperplasia or liver portal fibrosis with the prevalence of 80％ (16/20) and 25％ (5/20),respectively.Conclusion SLE complicated by NCPH is very rare clinically and is easily being misdiagnosed without obvious symptoms and signs in the early stage.Positive ACL antibodies and Raynaud's phenomenon maybe be closely related to SLE complicated by NCPH.

Objective To evaluate the clinical and radiographic characteristics and function of erosive hand osteoarthritis (EOA) patients. Methods Data were obtained from 19 patients with EOA, including their social conditions, clinical conditions, radiographic scores and hand function evaluation. The number of hand osteoarthritis (HOA) patients was 312. The control group consisted of non-EOA patients with hand osteoarthritis with a ratio of 4:1 to EOA patients. A non-parameter test analysis was performed. All data were analyzed by SPSS 23.0 statistical analysis, t test, χ2 test, Fisher exact probility and Spearman's correlations analysis were used for statistical analysis. Results Totally data of 19 patients were collected. Eighteen were female. Onset age was (56±8). Average duration was 56 (12~120) months. FIHOA scores of all the EOA patients were at least 5. All the erosions of 39 joints were characteristically central and erosive changes in 7 joints (18%) showed up as gull-wing. Among 39 erosive joints, including 12 (31%) E and 27 (69%) R, 34 (87%) distal interphalangeal joints were involved. Data analysis found out that EOA patients had longer disease duration (Z=2.610, P=0.009), more severe K-L level (44 ±11 vs 26 ±7, t=7.134, P<0.01), higher AUSCAN total score (28±6 vs 21±7, t=3.781, P<0.01) and higher AUSCAN function score (18±6 vs 12±6, t=4.042, P<0.01). The differences of ESR and CRP were not significant between EOA and non-EOA patients. Conclusion Erosions seen in EOA patients are centrally located gull-wing in the DIP joints. EOA patients have longer duration, more severe radiographic damage and worse joint function.

Objective To study different groups of deficiency rate of glucose-6-phosphate dehydrogenase (G6PD)and enzyme activity assay in the detection rate of female heterozygote in the Southeast Dongguan.Methods From January 2007 to April 2013,of 39 475 cases of test results were collected in Tangxia Hospital of Dongguan city,the gene frequency and the detec-tion rate of female heterozygote could be calculated through genetic equilibrium law in different group.Results The male de-ficiency rates of G6PD in different group were Adult group(A)5.03%,Neonatal Group(B)5.10% and Total group(C) 5.06%,respectively,and there were no significant difference between each groups (χ2 =0.0404,P =0.980).The detection rate of female heterozygote of A,B and C in each groups were 27.13%,14.49% and 23.87%,respectively,and the differ-ence were statistically significant between different groups (χ2 =32.26,P =0.000).Conclusion Prevalence of G6PD defi-ciency in this area was 5.06% and there were differences between the deficiency rate of G6PD in different populations.The enzyme activity assay in female heterozygote detection rate is not satisfactory,especially in group B,which is conducive to ge-netic counseling,prenatal diagnosis and birth defects,such as providing more comprehensive information.

Objective To analyze the risk factors associated with acute renal failure (ARF) in critically ill obstetric patients in intensive care unit (ICU).Methods A retrospective analysis of 192 critically ill obstetric patients admitted to the ICU for postpartum complications was conducted. There were 10 patients excluded because 3 died of amniotic embolism with massive hemorrhage in ICU and 7 had incomplete records, therefore, only 182 critically ill obstetric patients were enrolled in this study. According to the occurrence of ARF or not, the patients were divided into ARF group (68 cases) and non-ARF group (114 cases). The indicators of preeclampsia, HELLP syndrome (hemolysis, elevated liver enzymes, thrombocytopenia), acute fatty pregnancy liver, postpartum hemorrhage, sepsis were collected in the two groups. The main drugs used in the 4 days after delivery were as follows: ① plasma volume expanders: fluids (crystalloids, artificial colloids, hypertonic albumin and 4% serum albumin) and blood products (packed red cells, concentrated platelets, fibrinogen, fresh frozen plasma and activated factor Ⅶ); ② antifibrinolytic drug: tranexamic acid; ③ anti-hypertensive drugs: angiotensin-converting enzyme inhibitors (ACEI), diuretics; ④ nephrotoxic drugs: aminoglycosides, contrast agent. The above indexes were firstly analyzed by the univariate method, and the risk factors with statistical significance were further analyzed by multivariate logistic regression method to screen out the independent risk factors of developing ARF in critically ill obstetric patients in ICU.Results Univariate analysis showed that HELLP syndrome, tranexamic acid and hypertonic albumin infusion used in 4 days after delivery were the risk factors of ARF (χ2 value was 4.92, 4.29, 5.53, respectively, allP < 0.05). The multivariate logistic regression analysis showed: HELLP syndrome [odds ratio (OR) = 10.478, 95% confidence interval (95%CI) was 1.248 - 17.953,P = 0.030] and hypertonic albumin infusion used in 4 days after delivery [OR = 6.632, 95%CI was 1.211 - 16.328,P = 0.029] were the independent risk factors to develop ARF.Conclusions The occurrence of ARF in a critically ill obstetric patient in ICU is a process involving multiple factors, therefore, it is necessary to fully recognize the risk factors influencing the development of this disease; the presence of HELLP syndrome and hypertonic albumin infusion used in 4 days after delivery are the independent risk factors of developing ARF. Thus, particular attention should be paid to those patients with such high risk factors to decrease the incidence of ARF.
