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.

Tumor-associated tertiary lymphoid structures(TLSs)are ectopic lymphoid formations within tumor tissue,with mainly B and T cell populations forming the organic aggregates.The presence of TLSs in tumors has been strongly associated with patient responsiveness to immunotherapy regimens and improving tumor prognosis.Researchers have been motivated to actively explore TLSs due to their bright clinical application prospects.Various studies have attempted to decipher TLSs regarding their formation mechanism,structural composition,induction generation,predictive markers,and clinical utilization.Meanwhile,the scientific approaches to qualitative and quantitative descriptions are crucial for TLS studies.In terms of detection,hematoxylin and eosin(H&E),multiplex immunohistochemistry(mIHC),multiplex immunofluorescence(mIF),and 12-chemokine gene signature have been the top approved methods.However,no standard methods exist for the quantitative analysis of TLSs,such as absolute TLS count,analysis of TLS constituent cells,structural features,TLS spatial location,density,and maturity.This study reviews the latest research progress on TLS detection and quantification,proposes new directions for TLS assessment,and addresses issues for the quantitative application of TLSs in the clinic.

Objective:To retrospectively analyze the long-term survival (10-15 years) and late toxicity of nasopharyngeal carcinoma (NPC) patients after intensity-modulated radiotherapy (IMRT), aiming to provide reference for the optimal treatment of NPC.Methods:132 patients with NPC who were treated with IMRT in Sichuan Cancer Hospital from 2003 to 2009 were recruited. Among them, 3 patients were classified as stage Ⅰ, 22 cases of grade Ⅱ, 61 cases of grade Ⅲ, 43 cases of Ⅳ A and 3 cases of Ⅳ B, respectively. The median dose was 73.37Gy (66 to 85Gy), divided into 33 times. Twenty patients received radiotherapy alone, 112 cases of concurrent radiochemotherapy. The survival rate was calculated by Kaplan-Meier method and log- rank test. Univariate prognostic analysis was performed. Cox model was used to conduct multivariate prognostic analysis. The late radiation toxicity was evaluated by RTOG/EORTC criteria. Results:The median follow-up duration was 128 months (range, 3 to 191 months). The 10-and 15-year local control rates of NPC patients were 86.0% and 79.9%. The disease-free survival rates were 72.5% and 63.2%, and the overall survival (OS) rates were 65.2% and 57.1%. The local recurrence rate was 12.1%, and the distant metastasis rate was 16.7%. A total of 53 patients died, of whom 15 patients died of local recurrence, 20 patients died of distant metastasis and 18 patients died of other diseases (pneumonia, intracranial hemorrhage and accident, etc.). The 10-and 15-year non-tumor-related mortality rates were 11.3% and 13.6%. Univariate analysis showed that age, smoking habit, lactate dehydrogenase (LDH), T stage and clinical stage were the independent prognostic factors of OS in NPC patients. Multivariate analysis demonstrated that LDH, T stage and synchronous chemotherapy were the prognostic factors of OS in NPC patients. The incidence of gradeⅠ-Ⅱ late radiation injury (hearing impairment, dysphagia, dental caries and xerostomia) was 90.4%, and 8.5% for grade Ⅲ-Ⅳ late radiation injury (skin fibrosis, hearing impairment and radiation brain injury).Conclusions:The 10-and 15-year OS of NPC patients treated with IMRT is relatively high. With the prolongation of survival, the non-tumor-related mortality rate is increased. Distant metastasis is the main cause of treatment failure. The main late injuries include grade Ⅰ/Ⅱ hearing impairment, dysphagia, dental caries and xerostomia.

Objective:To investigate the isolation characteristics and the antibiotic resistance of Streptococcus pneumoniae in hospitalized children from the Bao′an District of Shenzhen for many consecutive years, and to provide evidence for the assessment as well as clinical prevention and treatment of Streptococcus pneumoniae infection. Methods:The isolation rate and sample source of Streptococcus pneumoniae isolates as well as age composition of hospitalized children in Bao′an Maternal and Child Health Hospital of Shenzhen city from January 2012 to December 2018 were retrospectively analyzed.The susceptibility of the isolates to antibiotics was tested by disk diffusion method and E-test method. Results:(1) From 2012 to 2018, a total of 90 807 specimens were retrospectively summarized, 9 193 strains of Streptococcus pneumoniae were isolated, with an isolation rate of 10.1%, which was the first pathogen; 98.68% (9 072/9 193 cases) from respiratory tract samples and 97.20% from sputum samples.Among 107 strains isolated from aseptic body fluid specimens, 97 strains were blood specimens. Streptococcus pneumoniae was the most common bacteria with positive culture in aseptic body fluids.(2) The isolation rate of Streptococcus pneumoniae was 10.7% in children under 2 years old, 10.2% in children between 2 and 5 years old and 4.1% in children over 5 years old.About 97% of Streptococcus pneumoniae isolates came from children under 5 years old.(3) According to breakpoints of non-meningitis strains, the sensitivity rate of parenteral Penicillin was 93.18%, the mediation rate was 6.79%, the resistance rate was only 0.03%, the lowest drug concentration to inhibit the growth of 50% bacteria(MIC 50) value was 0.50 and the lowest drug concentration to inhibit the growth of 90% bacteria(MIC 90) value was 2.00; the sensitivity rate of Ceftria-xone was 76.55%, the mediation rate was 20.18%, the resistance rate was 3.26%, the MIC 50 value was 1.00 and the MIC 90 value was 2.00; when interpreted by the breakpoint of meningitis strains, the resistance rate of extra-gastrointestinal Penicillin reached 77.22%, and the mediation rate of Ceftriaxone increased to 30.48% and the drug resistance rate reached 18.45%.The drug resistance rates of Erythromycin, Clindamycin, Tetracycline and Compound neomycin were all over 85.00%.The resistance rates against Levofloxacin and Chloramphenicol were 0.16% and 7.85% respectively.No Vancomycin-resistant Streptococcus pneumoniae was found. Conclusions:Streptococcus pneumoniae is the first bacterial pathogen causing respiratory tract and invasive infection in hospitalized children under 5 years old in this area.Penicillin is still the preferred drug for non-meningitis pneumococcal infection, but the drug resistance rate is high in meningitis patients.

OBJECTIVETo evaluate the effect of techniques of precise liver surgery for donor hepatectomy in living donor liver transplantation.

METHODSEighty-nine donors aged from 19 to 57 years were performed by the same surgical team from June 2006 to December 2013 in Chinese People's Liberation Army General Hospital.Individualized surgical program were developed according to preoperative imaging examination and hepatic functional reserve examination. The evaluation included liver function, liver volume, vascular anatomy and bile duct anatomy. According to the results after the operation, preoperative evaluation accuracy, postoperative donor liver function and postoperative complications were analyzed. ANOVA analysis was used to compare the difference of graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight. Pearson correlation test and linear regression analysis were used to verify the correlation between the estimated graft volume each method and actual graft postoperative weight.

RESULTSAll the 89 cases operation protocol as following, there were 5 cases with left lateral lobe graft, 10 cases with left lobe liver graft, 74 cases with right lobe graft. There were 59 cases with middle hepatic vein (MHV) harvested, and 30 cases without MHV. The mean graft volume by two-dimensional, three-dimensional calculation method and actual postoperative graft weight were (656.2±134.1) ml, (631.7±143.2) ml and (614.5±137.7) ml respectively. ANOVA analysis results showed that there were no statistically significant difference in the three methods (P>0.05). Compared to the actual postoperative graft weight, the average error rate of the two methods were 7.9% and 5.3% respectively. Pearson correlation test showed the graft volume calculated by two-dimensional and three-dimensional methods had a significantly positive correlation with actual graft weight (r=0.821, 0.890, P<0.01) and linear regression analyze showed the R2 were 0.674 and 0.792, respectively. The accuracy rate of preoperative evaluation about portal vein, hepatic vein, hepatic artery and bile duct were 100%, 100%, 97.8% and 95.5%, respectively. The preoperative plan and postoperative practical scheme coincidence rate was 95.5%. Overall donor complication rate was 7.4%. All donors were alive. Sixteen donors received right lobe hepatectomy with gallbladder preserved had a good liver function and gallbladder function.

CONCLUSIONThrough the precise preoperative evaluation, surgical planning, fine operation and excellent postoperative management, precise liver surgery technique can ensure the safety of donor in living donor liver transplantation.

In recent 20 years, the most important advancement of rectal cancer surgery is the total mesorectal excision(TME) and laparoscopic minimal invasive surgery. However, visualization of the distal rectum is still troublesome because of narrow pelvic, bulky tumor, and especially obese male patients. A possible solution for this situation is distal rectal mobilization by transanal minimally invasive surgery (TAMIS), or even pure transanal total mesorectal excision (taTME). When people applaud a new era of rectal cancer surgery is coming, we must also concern about the patients selection, the long-term follow up results and even the operative safety.

Objective To discuss the application effect of clinical nursing pathway of Traditional Chinese Medicine ( TCM) in facial paralysis patients. Methods A total of 80 cases of facial paralysis patients from February 2012 to August 2014 were randomly divided into the observation group ( n=40 ) and the control group (n=40) according to random number table method. The control group was adopted routine treatment and nursing care, while the observation group was given clinical nursing pathway of TCM treatment and nursing care. The average length of hospital stay, hospital expenses, nursing compliance and satisfaction were compared. Results The hospitalization time and cost of the observation group were (13 ± 2. 3) days and (7 382. 0 ± 123. 1) yuan, which were significantly better than those of the control group (t=10. 70, 39. 55, respectively;P<0. 05). In the observation group, 36 patients were totally complied, three patients were partially complied, and one patient was not complied, which were significantly better than those of the control group (Z=4. 96,P<0. 05). In the observation group, 37 patients were totally satisfied, three patients were basically satisfied, and no patient was not satisfied, which were significantly better than those of the control group (Z =4. 97,P <0. 05). Conclusions The application of TCM clinical nursing pathway in facial paralysis patients can reduce the length of hospital stay and hospital costs, and improve patients′care compliance and satisfaction.
