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 quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

Objective: To explore the clinical characteristics and genotype of PROS1 gene related hereditary protein S deficiency (PSD) with the onset of pulmonary embolism in children. Methods: A family with pulmonary embolism was diagnosed as hereditary PSD in the Department of Pediatrics of Peking University First Hospital in November 2020, and the clinical data, including clinical manifestations, laboratory tests, imaging and genetic results, were collected for a retrospective research. The family members were also screened for protein S activity and PROS1 gene mutations. A literature search with "PROS1" "protein S deficiency" "homozygous" and "complex heterozygous" as key words was conducted at PubMed, China National Knowledge Infrastructure, and Wanfang Data Knowledge Service Platform (up to October 2021). Case reports of patients with PROS1 gene homozygous or complex heterozygous variants and related clinical features, protein S activity, and genotype were reviewed and analyzed. Results: The proband, a 14-year-old girl, was admitted to the hospital for a 9-day history of coughing and a 4-day history of chest pain in November 2020. After admission, laboratory tests showed that D-dimer was 8.38 mg/L (reference:<0.24 mg/L). An urgent CT pulmonary angiography confirmed bilateral pulmonary embolism and right lower pulmonary infarction, while an ultrasonography showed deep vein thrombosis in her left leg. Further examination revealed that protein S activity was less than 10%. The proband's second sister, a 12-year-old girl, was admitted to the hospital in December 2020. Her protein S activity was 8% and an ultrasonography showed deep vein thrombosis in her right leg. The protein S activity of the proband's father and mother were 36% and 26%, respectively. Trio-whole-exome sequencing detected compound heterozygous PROS1 gene variants (c.-168C>T and c.200A>C (p.E67A)) for the proband and her second sister, that were inherited from her father and mother, respectively. The proband's third sister's protein S activity was 28%; she and the proband's grandfather both carried c.200A>C (p.E67A) variants. The proband and her younger sister were treated with rivaroxaban and responded well during the 3-month follow-up. A total of 1 Chinese report in literature and 18 English literature were retrieved and 14 patients with protein S deficiency caused by homozygous or complex heterozygous variants of PROS1 gene were enrolled, including 8 male and 6 female patients. The ages ranged from 4 days to 35 years. Three patients experienced fulminant purpura or severe intracranial hemorrhage in early neonatal-period, while the remaining 11 patients developed venous thromboembolism in adolescence. Protein S activity was examined in 11 patients, and all showed less than 10% of activity. Missense variants was the most common type of gene variants. Conclusions: For children with pulmonary embolism, if there are no clear risk factors for thrombosis, hereditary protein S deficiency should be considered, and protein S activity should be examined before oral anticoagulant drugs. If protein S activity is less than 10%, protein S deficiency caused by homozygous or complex heterozygous variants should be considered.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Tumors are new organisms formed by uncontrollable cell proliferation of local tissues driven by various oncogenic factors. The cause of tumors is unknown with life-threating outcome. Tumors can be classified into benign tumors， borderline tumors， and malignant tumors according to their pathological properties. Among them， malignant tumor is commonly known as cancer， with no specific medicines or reliable cure means， so this is a hot spot and difficult point in current medical research. In ancient literatures， there are many records about the efficacy of Chinese herbal medicine in treating tumor， and modern pharmacological researches have shown that more and more active ingredients of traditional Chinese medicine（TCM） have gradually highlighted their inhibitory effect on various types of tumor. Caulis sinomenii has been used for treatment of rheumatic diseases in TCM for a long history. Sinomenine is a major bioactive alkaloid presented in C. sinomenii， which has demonstrated a wide range of pharmacological activities such as anti-inflammation， immunosuppression， analgesia and sedation， and due to its slightly soluble in water， it is commonly used in clinic in the form of hydrochloride， with its commercial name of Zhengqing Fengtongning. Recent studies show that sinomenine alone or combined with chemoradiotherapy can inhibit growth of several tumors significantly or in a synergistic way， so it is termed as an inhibitor of tumors. Anti-tumor effect of sinomenine involve inhibition of tumor cell proliferation， induction of tumor cell apoptosis， blockade of tumor cell cycle， suppression of tumor invasion and metastasis， induction of autophagy of tumor cells， and reversal of multidrug resistance of tumor cells. Upon combination with nanomaterials， it can enhance efficiency and reduce toxicity. Here we summarized and reviewed recent advances on basic anti-tumor research of sinomenine， and then made a classification and description according to its in vivo and in vitro pharmacological action and mechanism of action， so as to elucidate the great potential of sinomenine as a promising anti-tumor drug， and provide reference for further research on its anti-tumor mechanism.

To optimize the ethanol extraction technology parameters of Fengyin Decoction by orthogonal experiment combined with beetle antennae search(BAS)-genetic algorithm(GA)-back propagation neural network(BPNN). Based on single factor investigation, the extraction temperature, ethanol volume, extraction time, and ethanol concentration were used as orthogonal experiment factors, and entropy weight method was used to calculate the comprehensive scores of aloe-emodin, glycyrrhizic acid ammonium salt, rhein, emodin, chrysophanol, physcion, cinnamaldehyde, 6-gingerol, extraction ratio and fingerprint similarity. BAS-BPNN model was established, and then, GA was used to predict the optimal extraction process. The results showed that BAS-BPNN was optimized to obtain the optimal ethanol extraction process of Fengyin Decoction as follows: extraction temperature of 87 ℃, adding 9 times of 75 % ethanol, and extracting for 47 minutes, with a comprehensive score of 1.052 9. Meanwhile, the optimal process parameters obtained by orthogonal design were as follows: the extraction temperature of 80 ℃, adding 10 times of 75% ethanol, extracting for 30 minutes, with a comprehensive score of 1.003 7. The comprehensive score of the process obtained from the BAS-BPNN model was slightly better than that from the orthogonal test, indicating that the optimized process from BAS-BPNN model was more ideal, so it was finally determined as the best extraction process for Fengyin Decoction. The process of Fengyin Decoction obtained from BAS-GA-BPNN has high extraction efficiency and good stability, which provides reference for the subsequent development and quality control.

To study the clinical effect of oral sirolimus in the treatment of children with blue rubber bleb nevus syndrome (BRBNS) in the gastrointestinal tract, a retrospective analysis was performed on the clinical data and follow-up results of two children with BRBNS treated by sirolimus. The two children with BRBNS had gastrointestinal bleeding and anemia and were treated with sirolimus at a dose of 1 mg/day as part of treatment. The plasma concentration of the drug was maintained between 2.5-12.0 ng/mL. The children showed disappearance of gastrointestinal bleeding and improvements in anemia and coagulation function, and blood transfusion could be stopped during treatment, with no obvious adverse drug reactions. PubMed, Wanfang Data, and CNKI were searched for related articles on sirolimus in the treatment of BRBNS. A total of 26 cases of children with BRBNS, aged 0-18 years, were obtained. With the addition of the 2 cases in this study, sirolimus treatment achieved a satisfactory clinical effect in all 28 cases. Sirolimus may be effective and safe in the treatment of children with BRBNS, and further prospective studies are needed to evaluate the long-term efficacy of this drug.
