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 analyze the clinical efficacy of microwave ablation in the colorectal cancer with simultaneously multiple liver metastases that was initially evaluated as potentially resectable.Methods The patients with potentially resectable colorectal cancer with simultaneous multiple liver metastases treated in the De-partment of General Surgery of the First Affiliated Hospital of Hebei North University,the Center of Minimally Invasive Therapy in Oncology of Traditional Chinese and Western Medicine in Dongzhimen Hospital of Beijing U-niversity of Chinese Medicine,and the Second Department of General Surgery in the Fourth Hospital of Hebei Medical University from October 1,2018 to October 1,2020 were selected in this study.The general data,pathological features,treatment methods,and clinical efficacy of the patients were collected.According to the treatment methods,the patients were assigned into a surgical resection group(conversion therapy + laparoscopic primary resection +hepatectomy)and a microwave ablation group(conversion therapy +laparoscopic primary re-section +microwave ablation).The surgical indicators(operation duration,time to first postoperative anal ex-haust,hospital stay,etc.)and postoperative complications(anastomotic stenosis,anastomotic hemorrhage,incision infection,etc.)were compared between the two groups.The survival period was followed up,including the overall survival period and disease-free survival period,and the survival curves were drawn to analyze the clinical efficacy of the two treatment regimens.Results A total of 198 patients with potentially resectable color-ectal cancer with simultaneous multiple liver metastases were included in this study.Sixty-six patients were cured by neoadjuvant chemotherapy(FOLFOX or FOLFIRI),including 30 patients in the surgical resection group and 36 patients in the microwave ablation group(with 57 tumors ablated).After the first ablation,54(94.74%)tumors achieved complete ablation,and all of them reached no evidence of disease status after re-ablation.The microwave ablation group had shorter operation duration,less intraoperative blood loss,shorter time to first post-operative anal exhaust,shorter time of taking a liquid diet,shorter hospital stay,and lower hospitalization cost than the surgical resection group(all P<0.001).In addition,the microwave ablation group had lower visual analogue scale score(P<0.001)than the surgical resection group.The incidences of complications such as inci-sion infection(P =0.740),anastomotic fistula(P =1.000),and anastomotic stenosis(P =1.000),the over-all survival period(P =0.191),and the disease-free survival period(P =0.934)showed no significant differ-ences between the two groups.Conclusions For patients with colorectal cancer with simultaneous multiple liver metastases initially assessed as potentially resectable,laparoscopic primary resection +surgical resection/microwave ablation after conversion therapy was safe,effective,and had similar survival outcomes.Microwave ablation outper-formed surgical resection in postoperative recovery,economy,and tolerability,being worthy of clinical promotion.

Objective:To evaluate the effectiveness and safety of concurrent chemoradiotherapy combined with nimotuzumab in the treatment of patients with inoperable esophageal squamous cell carcinoma (ESCC).Methods:A retrospective analysis was conducted on the clinical data of 503 patients with inoperable ESCC who underwent concurrent chemoradiotherapy in the Department of Radiation Oncology, Changzhou No. 2 People′s Hospital Affiliated to Nanjing Medical University and Department of Radiation Oncology, Affiliated Hospital of Jiangnan University from 2014 to 2020. Among these patients, 69 received concurrent chemoradiotherapy combined with nimotuzumab (the combined therapy group) and 434 received concurrent chemoradiotherapy alone (the concurrent chemoradiotherapy group). Patients of both groups were matched at a ratio of 1∶2 using the propensity score matching (PSM) method. As a result, 168 patients were determined for clinical analysis, including 61 in the combined therapy group and 107 in the concurrent chemoradiotherapy group. The short-term efficacy and adverse reactions of both groups were compared. The overall survival (OS) curves and progression-free survival (PFS) curves were plotted using the Kaplan-Meier method for the Log-rank test.Results:The two groups showed no statistical difference ( P > 0.05) in clinical baseline characteristics after the PSM. The objective response rate (ORR) of the combined therapy group was significantly higher than that of the concurrent chemoradiotherapy group with statistically significant differences (85.2% vs. 71.0%, χ2 = 4.33, P = 0.037). There was no statistical difference (98.4% vs. 91.6%, P > 0.05) in the disease control rate (DCR) between the two groups. The combined therapy group had median PFS of 28.07 months and 1-, 3-, and 5-year PFS ratios of 78.2%, 37.5% and 29.1%, respectively. The concurrent chemoradiotherapy group had mPFS of 19.54 months and 1-, 3-, and 5-year PFS ratios of 72.9%, 28.3% and 21.3%, respectively. Both groups showed statistically significant differences in PFS ( χ2 = 4.49, P = 0.034). The combined group had median OS of 34.93 months and 1-, 3-, and 5-year OS ratios of 88.5%, 46.8% and 37.4%, respectively. The concurrent chemoradiotherapy group had mOS of 24.30 months and 1-, 3-, and 5-year OS ratios of 81.3%, 35.2% and 28.0%, respectively. Both groups showed statistically significant differences in OS (χ 2= 5.11, P = 0.024), but did not show statistical differences ( P > 0.05) in the severity degree of each adverse effect during the treatment. Conclusions:Concurrent chemoradiotherapy combined with nimotuzumab can improve the ORR and prolong the PFS and OS of patients with inoperable ESCC compared with concurrent chemoradiotherapy alone. Furthermore, combining with nimotuzumab does not increase adverse effects and can be tolerated by patients with high safety.

Immunosuppression is a key element of poor prognosis in patients with sepsis. The immune status assessment is a prerequisite for identifying immunosuppressed patients and clarifying the timing of immunotherapy. Exploring biomarkers for immune status assessment in sepsis has become a current hot spot. However, the availability of a large number of biomarkers in recent years has presented clinicians with a selection problem. There is four criteria for ideal biomarkers of sepsis immunosuppression for the screening of potential biomarkers of sepsis immunosuppression.

Objective:To confirm the efficacy and safety of cinepazide maleate injection in acute ischemic stroke patients with obvious motor function deficit.Methods:This study is a subgroup analysis of multi-center, randomized, double-blind, placebo-controlled phase Ⅳ clinical trial. A total 812 patients of acute ischemic stroke with obvious limb motor deficit [motor function of limbs score in National Institutes of Health Stroke Scale (NIHSS) ≥4] were enrolled in this subgroup analysis. Patients received either cinepazide maleate injection or placebo. The treatment period was 14 days and follow-up was 90 days. The efficacy endpoints included the proportions of patients with a modified Rankin Scale (mRS) score ≤2, mRS score ≤1 and Barthel Index <95 on day 90. Safety was evaluated by recording all adverse events, monitoring vital signs, laboratory parameters and electrocardiogram.Results:A total of 732 patients were involved in the final efficacy analysis (361 in cinepazide maleate group and 371 in control group). The baseline limb motor function score of NIHSS was 5.23±1.43 in the cinepazide maleate group whereas 5.20±1.36 in the control group. Logistic regression analysis showed that following treatment for 90 days, the proportion of patients with a mRS score ≤2 was significantly higher in the cinepazide maleate group than in the control group [56.0% (202/361) vs 44.2% (164/371), OR=0.60, 95% CI 0.44-0.82, P=0.002]. The proportion of patients with a mRS score ≤1 was higher in the cinepazide maleate group than in the control group [43.3% (139/361) vs 35.2% (118/371), OR=0.69, 95% CI 0.50-0.97, P=0.031]. The proportion of patients with a Barthel Index <95 on day 90 was significantly lower in the cinepazide maleate group than in the control group [45.2% (145/361) vs 55.2% (185/371), OR=0.64, 95% CI 0.46-0.88, P=0.007]. During the treatment and follow-up period, the incidence of the most common adverse events in the cinepazide maleate group was 50.4% (199/395). Constipation and abnormal liver function were more common, but there were no statistically significant differences between the two groups. Conclusion:Cinepazide maleate injection is superior to placebo in improving neurological function and activities of daily living, reducing disability, and promoting functional recovery and safe in patients with acute ischemic stroke with obvious limb motor deficit.

In the emergency of the outbreak of COVID-19 in December 2019, Shaanxi Provincial Health Committee mobilized several medical teams from major hospitals in the province, and, by relying on Xi’an Chest Hospital, jointly established an anti COVID-19 consortium to control and eradicate the epidemic in a short time. Information support is an important guarantee for winning this battle. In order to realize the efficient cooperation among multiple medical teams, we have carried out some exploratory and innovative information support services on the basis of the original information system of the chest hospital. In this process, we have gone through some detours. Some compromises were made on some problems that could not be solved in the short term. Finally, in an environment full of uncertainty, a set of information support management system with basically smooth operation was built through rapid trial and error adjustment. The system mainly includes the following aspects: support of the organizational structure and operation process of the anti-epidemic consortium, support for medical collaboration related businesses of multiple medical teams, and support for statistical reports and online meetings. Information support has played a very important role in this action, and this practice has also accumulated experience for us to deal with similar situations in the future.

Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.

Objective:To investigate the blood pressure change in patients with acute ischemic stroke (AIS) and hypertension treated with cinepazide maleate injection.Methods:This was a subgroup analysis of post-marketing clinical confirmation study of cinepazide maleate injection for acute ischemic stroke: a randomized, double-blinded, multicenter, placebo-parallel controlled trial, which conducted in China from August 2016 to February 2019. Eligible patients fulfilled the inclusive criteria of acute anterior circulation ischemic stroke with National Institutes of Health Stroke Scale (NIHSS) scores of 7-25. The primary endpoints were mean blood pressure of AIS patients treated with cinepazide maleate or control, which were assessed during the treatment period (14 days), and the proportion of the patients with normal blood pressure was analyzed after the treatment period. Furthermore, a subgroup analysis was performed to investigate a possible effect of the history of hypertension on outcomes.Results:This analysis included 809 patients with hypertension. There was no significant difference in patients blood pressure and the proportion of patients with normal blood pressure (60.5% vs. 59.0%, P>0.05) between cinepazide maleate group and control group. Conclusion:Administration of cinepazide maleate injection does not affect the management of clinical blood pressure in patients with AIS.

Objective : To investigate the clinical efficacy of anterolateral thigh flap(ALTF) repair on postoperative soft tissue defects in oral malignant tumors. Methods : The clinical data of 136 oral malignant tumor patients at the Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital from June 2017 to February 2019 were collected. All the patients had undergone enlarged tumor resection, and the defects were repaired simultaneously by ALTF. The flap survival rate and occurrence of postoperative complications were analyzed, and related functions were evaluated. Results : The flap survival rate was 97.1% (132/136). Diabetes and the operation time were related to inactivation of the anterolateral thigh flap (P < 0.05). Fifty-three patients (40.0%) had systemic complications, and 38 patients (27.9%) had complications in the operation area, among which the pulmonary infection rate was the highest (28.6%). One year after the operation, 52 patients (38.2%) scored 10 points in language function evaluation. The mouth opening score of 58 patients (42.6%) was 10 points, and the swallowing function score of 82 patients (60.3%) was 10 points. Conclusion ALTF is an ideal free flap to repair soft tissue defects in oral and maxillofacial malignant tumors after resection, with a high survival rate, small donor injury and good postoperative recovery of relevant functions.
