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.

Background::Cardiovascular disease (CVD) has emerged as the leading cause of death from prostate cancer (PCa) in recent decades, bringing a great disease burden worldwide. Men with preexisting CVD have an increased risk for major adverse cardiovascular events when treated with androgen deprivation therapy (ADT). The present study aimed to explore the prevalence and risk evaluation of CVD among people with newly diagnosed PCa in China.Methods::Clinical data of newly diagnosed PCa patients were retrospectively collected from 34 centers in China from 2010 to 2022 through convenience sampling. CVD was defined as myocardial infarction, arrhythmia, heart failure, stroke, ischemic heart disease, and others. CVD risk was estimated by calculating Framingham risk scores (FRS). Patients were accordingly divided into low-, medium-, and high-risk groups. χ2 or Fisher’s exact test was used for comparison of categorical variables. Results::A total of 4253 patients were enrolled in the present study. A total of 27.0% (1147/4253) of patients had comorbid PCa and CVD, and 7.2% (307/4253) had two or more CVDs. The enrolled population was distributed in six regions of China, and approximately 71.0% (3019/4253) of patients lived in urban areas. With imaging and pathological evaluation, most PCa patients were diagnosed at an advanced stage, with 20.5% (871/4253) locally progressing and 20.5% (871/4253) showing metastasis. Most of them initiated prostatectomy (46.6%, 1983/4253) or regimens involving ADT therapy (45.7%, 1944/4253) for prostate cancer. In the present PCa cohort, 43.1% (1832/4253) of patients had hypertension, and half of them had poorly controlled blood pressure. With FRS stratification, as expected, a higher risk of CVD was related to aging and metabolic disturbance. However, we also found that patients with treatment involving ADT presented an originally higher risk of CVD than those without ADT. This was in accordance with clinical practice, i.e., aged patients or patients at advanced oncological stages were inclined to accept systematic integrative therapy instead of surgery. Among patients who underwent medical castration, only 4.0% (45/1118) received gonadotropin releasing hormone antagonists, in stark contrast to the grim situation of CVD prevalence and risk.Conclusions::PCa patients in China are diagnosed at an advanced stage. A heavy CVD burden was present at the initiation of treatment. Patients who accepted ADT-related therapy showed an original higher risk of CVD, but the awareness of cardiovascular protection was far from sufficient.

Alkali-salinity exerts severe osmotic, ionic, and high-pH stresses to plants. To under-stand the alkali-salinity responsive mechanisms underlying photosynthetic modulation and reactive oxygen species (ROS) homeostasis, physiological and diverse quantitative proteomics analyses of alkaligrass (Puccinellia tenuiflora) under Na2CO3 stress were conducted. In addition, Western blot,real-time PCR, and transgenic techniques were applied to validate the proteomic results and test the functions of the Na2CO3-responsive proteins. A total of 104 and 102 Na2CO3-responsive proteins were identified in leaves and chloroplasts, respectively. In addition, 84 Na2CO3-responsive phospho-proteins were identified, including 56 new phosphorylation sites in 56 phosphoproteins from chloro-plasts, which are crucial for the regulation of photosynthesis, ion transport, signal transduction, and energy homeostasis. A full-length PtFBA encoding an alkaligrass chloroplastic fructose-bisphosphate aldolase (FBA) was overexpressed in wild-type cells of cyanobacterium Synechocystis sp. Strain PCC 6803, leading to enhanced Na2CO3 tolerance. All these results indicate that thermal dissipation, state transition, cyclic electron transport, photorespiration, repair of pho-tosystem (PS) Ⅱ, PSI activity, and ROS homeostasis were altered in response to Na2CO3 stress, which help to improve our understanding of the Na2CO3-responsive mechanisms in halophytes.

CONCLUSIONS： Roflumilast can improve lung function and dyspnea in Asian COPD patients， but it can increase the risk of ADR.

Background Thyroid associated ophthalmopathy (TAO) is an autoimmune disease.Current research on the pathogenesis focuses on common autoantigen.Insulin-like growth factor-1 receptor (IGF-1R) is necessary for the function of IGF-1,also IGF-1 plays an important role in signaling pathway of thyroid stimulating hormone receptor (TSHR).Objective This study was to investigate the effects of IGF-1 on the proliferation,expression of IGF-1R and TSHR on cultured orbital fibroblasts (OFs) derived from TAO.Methods Human orbital tissue was obtained from 17 TAO patients who received orbital adipectomy and 4 normal controls who received cosmetic surgery in West China Hospital from March 2016 to June 2016.OFs were cultured by explant culture with DMEM/F12 containing 5％ fetal bovine serum and identified by immunochemistry.The OFs were treated with different concentrations of IGF-1.IGF-1 at different concentrations (0,50,100,125 μg/L) was added into the medium,respectively,and the proliferation of the cells (absorbancy) was detected by MTS.The percentages of IGF-1R and TSHR expressions in the cells were assayed by flow cytometry.Results Cultured cells appeared to be spindle-like in shape and grew well with abundant cytoplasm.The characteristics of the cells derived from TAO patients were consistant with normal ones.The cells showed the positive response for vimentin and absent respose for desmin,S-100,myoglobin and cytokeratin.The proliferative values of OFs were gradually elevated with the increase of IGF-I dose in both TAO group and normal group (Fgroup =219.639,P＜0.001;F ion =17.752,P＜0.001) with the optimal effects in 100 μg/L IGF-1.The expression levels of IGF-1R in the OFs were (0.009 1 ±0.008 7)％,(0.095 3±0.023 3) ％,(0.083 7±0.022 7) ％ and (0.070 9 ± 0.024 1) ％ in the TAO group,and those in the normal group were (0.0023± 0.0006)％,(0.0093±0.0012)％,(0.0073±0.0015)％ and (0.0083±0.0012)％ after treatment of 50,100,125 μg/L IGF-1.The expression levels of IGF-1 R were significantly higher after treatment of 50,100 and 125 μtg/L IGF-1 than those treatment of 0 μg/L IGF-1 in both TAO group and normal group,and the expression levels of IGF-1R in the OFs were significantly increased in the TAO group compared with the normal group (all at P＜0.05).No statistical difference was seen in the TSHR expression between the TAO group and normal group after treatment of 0,50,100 and 125 μg/L IGF-1 (Fgroup =0.133,P ＞ 0.05;F ion =0.004,P ＞ 0.05).Conclusions IGF-1 can promote the proliferation of OFs and up-regulate the expression of IGF-1R in OFs.However,IGF-1 dose not play a regulating effect on the expression of TSHR in OFs.

Objective To investigate the expression levels of tumor necrosis factor alpha (TNF-α),interleukin-6(IL-6) and the change of serum ferritin in patients with intracranial aneurysm and its clinical significance.Methods 22 patients with intracranial aneurysm and 16 cases of traumatic brain injury who recevied operation in Department of Neurosurgery in Quzhou People's Hospital from Jan.2014 to Jan.2015 were enrolled as observation group and control group.The intracranial aneurysm tissues and normal cerebral vascular tissues were collected respectively to detect the situation of inflammatory cell infiltration,and the expression of TNF-α and IL-6 was detected by HE staining and immunohistochemical staining.The serum was collected on hospitalized,postoperative 3 days and postoperative 7 days to detect serum ferritin.Results The positive cells were observed in the observation group after immunohistochemical staining,in which the expression levels of TNF-α [(0.194 ± 0.074) vs.(0.135 ± 0.047),t =2.799] and IL-6 [(0.152 ± 0.057) vs.(0.103 ± 0.028),t =3.494] were significantly higher than those in the control group(P =0.008,0.001).The serum ferritin level in the observation group was significantly higher than that in the control group at postoperative 3d [(232.25 ± 105.26) ng/mL vs.(169.51 ± 66.24) ng/mL,t =2.097] and postoperative 7d[(263.39 ± 114.73) ng/mL vs.(166.57 ± 73.71) ng/mL,t =2.955] (P =0.043,0.005).The difference of serum ferritin on different day in the observation group also was statistically significant(F =8.625,P =0.003).Conclusion The expression levels of TNF-α and IL-6 in intracranial aneurysms were high,which may be one of the important factors in the formation of intracranial aneurysms,and it provides an important reference of early prevention and drug treatment for patients with intracranial aneurysm.The serum ferritin is related to the rupture and hemorrhage of intracranial aneurysm,which can be used to judge prognosis and guide rational treatment,and worth further study to confirm.

Objective To evaluate the clinical effects of thoracic close drainage with thin drainage tube assisted to thick drainage tube after video-assisted thoracic surgery(VATS)lobectomy. Methods We ret-rospectively reviewed 89 patients received VATS lobectomy in Chinese PLA General Hospital from January 2014 to September 2014. The patients with non-small cell lung cancer were divided into two groups:treatment group (50 patients)and control group(39 patients). Treatment group took thin tube assisted to thick tube of thoracic close drainage and control group took general thoracic closed drainage tube. We studied the operation time,the bleeding of operation,the number of lymph node dissection,time of first activity out of bed,the hospitalization time of post-operation,post-operative complications,the days of post-operative drainage,drainage volume,the effect of drainage,the VAS evaluation score of post-operative pain in the two groups. Results Compared with control group,there was no statistical significance in the differences of the time of operation[(2. 58 ± 0. 57)h vs(2. 57 ± 0. 50)h;t = 0. 127,P = 0. 681],bleeding of operation[(108. 00 ± 52. 84)ml vs(114. 10 ± 107. 18)ml;t = 0. 352,P = 0. 334],the number of lymph node dissection[(14. 20 ± 5. 95)vs(11. 21 ± 4. 71);t = 2. 576,P = 0. 068)],the staying time of drainage[(5. 66 ± 2. 53)d vs(5. 82 ± 2. 02)d;t =0. 324,P = 0. 219],the postoperative drainage volume[(1 141. 76 ± 819. 26)ml vs(1 022. 95 ± 464. 84) ml;t = 0. 889,P = 0. 367]and the occurrences of the post-operative complications(8. 00% vs 10. 25% ;χ2 =1. 750,P = 0. 726). There was statistical significance in the differences of the post-operative time of off-bed [(11. 28 ± 8. 78)h vs(13. 97 ± 7. 83)h;t = 4. 027,P = 0. 045],the time from surgery to discharge [(8. 36 ± 2. 63)d vs(9. 56 ± 2. 89)d;t = 2. 952,P = 0. 043]and the drainage effect(costophrenic angle sharp:72. 0% vs 46. 2% ;χ2 = 5. 329,P = 0. 017). In the two groups,there were statistical significance differences in scores of VAS for the 24 to 72 hours resting and coughing of post-operation:24 h[(2. 78 ± 1. 13)vs(3. 74 ± 1. 68);t = 3. 226,P < 0. 001)],48 h[(1. 98 ± 0. 59)vs(3. 33 ± 1. 72);t = 5. 189,P <0. 001)],72 h[(1. 94 ± 0. 55)vs(3. 15 ± 1. 60);t = 5. 010,P < 0. 001)],coughing[(3. 64 ± 1. 23)vs (5. 33 ± 1. 95);t = 5. 005,P < 0. 001)]. Conclusion The thin drainage tube assisted to thick drainage tube for thoracic close drainage make the drainage more effective,release the pain,shorten the hopital stay;moreo-ver,it is simple and safe for operation and easy to popularize with high modified value.

Objective To approach the risk factors of bronchopulmonary dysplasia(BPD)with very low birth weight infants whose gestational age less than 32 weeks,thus it could provide a basis direction for prevention.Methods To summarize 70 neonates with BPD in October 2012 to October 2014 in our hospital, and randomly select 70 very low birth weight infants didn't have oxygen requirement of gestation age less than 32 weeks as control group.The perinatal risk factors,oxygen therapy and use caffeine were analyzed by using the statistical analysis of Chi-square test and logistic regression,so the risk factors and prevention direc-tion of BPD could be provided.Results Male gender were more prone to BPD(P ﹦0.000).Gestational age (P ﹦0.000)and birth weight(P ﹦0.002)were statistical lower in infants with BPD compared with no BPD.Family history of asthma,fetal distress,amniotic fluid turbidity,pulmonary hemorrhage,respiratory dis-tress syndrome,use of pulmonary surfactant,patent ductus arteriosus,intrauterine infection,ventilator time,na-sal continuous positive airway pressure /nasal intermittent positive pressure ventilation time,duration of oxy-gen therapy and use of caffeine were statistical significances (P 〈0.05,respectively).Logistic regression analysis demonstrated that gender(OR ﹦3.574,P ﹦0.003),gestational age≥28 weeks(OR ﹦58.665,P ﹦0.002), birth weight 〈1 250 g(OR ﹦36.453,P ﹦0.012)and ventilator time(OR ﹦703.696,P ﹦0.000)were independent risk factors for BPD infants.Using of caffeine(OR ﹦0.025,P ﹦0.010)and nasal continuous positive airway pressure/nasal intermittent positive pressure ventilation(OR ﹦0.004,P ﹦0.002)were protective factors for BPD infants. Conclusion The incidence of BPD could be reduced by strengthening prenatal care,minimizing intrauterine in-fection and preterm delivery,reducing the patent ductus arteriosus by strict fluid management,using mechanical ventilation rationally,choosing a non-invasive mechanical ventilation and caffeine.

Objective To investigate the effects of monocyte chemoattractant protein-1 (MCP-1) on the migration of neural stem cells in vivo. Methods The brain injured rat model was established with cortical micro-injection of lipopolysaccharide in Sprague-Dawley rats. The tissue of brain was immunohistochemistrically stained to detect the expression of MCP-1 and nestin 3 d, 5 d, and 7 d after modeling. Results The expression of MCP-1 increased, and reached a peak 5 d after modeling. The nestin-positive cells was found in the lipopolysaccharide injected area 7 d after modeling. Conclusion MCP-1 may induce the endogenous neural stem cells migrate to lipopolysaccharide injection area in vivo.

OBJECTIVE: To investigate the meaning of the mutation screening, prevalence, inheritance and the intervention or the prevention for the specific drugs in 10 families with non-syndrome hearing loss in Yunnan Province, China. METHOD: To do a questionnaire about the cases of ten families with non-syndrome hearing loss and to draw a detailed matriarchal family tree detailed. Following that, the A1555G mutation-positive individuals were detected and confirmed using DNA extracting, PCR amplification and sequencing for family volunteer. RESULT: There are 96 members have attended the blood collection in these ten families. Thirty-six of them had the normal hearing and 60 of them had the sensory neural hearing loss. However, 4 out of those had no A1555G point mutation, and 92 had A1555G point mutation (95.8%). While 7 of those were Heterogeneity, the rest were all homogeneous mutation. There were also 73 patients who had amino glycoside antibiotic medication history. However all the rest cases had a history of amino glycoside antibiotic medication were not clear yet. CONCLUSION The proportion of patients with drug-induced deafness is high in Yunnan province and the mutation rate of mitochondrial DNA A1555G is also high. It is worthy to do DNA 12SrRNA A1555G mutation screening for drug intervention and prevention.
