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 study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

Objective:To explore the RH genotype for a female with RhD(-) blood type and its molecular basis. Methods:A 26-year-old female who had attended the outpatient clinic of the First Affiliated Hospital of Zhengzhou University in August 2019 was selected as the study subject. Peripheral blood samples were collected from the proband and her parents for Rh phenotyping with gel card method. PCR-sequence-based typing (PCR-SBT) and DNA sequencing were used to determine the RHD zygosity and RH genotype of the proband and her parents. Homology modeling of Rh proteins was performed with bioinformatic software, and protein structural alterations caused by the variant was simulated by molecular dynamics. This study was approved by the Medical Ethics Committee of the First Affiliated Hospital of Zhengzhou University (Ethics No. 2023-KY-0870-003). Results:Serological tests showed that the proband and her father both had weakened e antigen of the Rh phenotype. PCR-SBT and DNA sequencing showed that the genotypes of the proband and her parents were dce/ dCE, dce/ DcE and dCE/ DcE, respectively. And the genotypes of the RHD and RHCE of the proband were RHD*01N.01/ RHD*01N.16, RHCE*01.01/RHCE*04, respectively. Protein simulation and molecular dynamics analysis revealed that the ce_16C variant resulted from RHCE* ce (c.48G>C) may alter the structure of intracellular and extracellular loops, mainly affecting the mobility of extracellular loops 2, 6 and intracellular loops 3, 4. Conclusion:Variant of the RHCE* ce allele c. 48G>C probably underlay the weakened e antigen in this proband.

Objective To explore the clinical value of serum protein kinase N1(PKN1),tumor necrosis factor receptor superfamily member 4(TNFRSF4),and DNA damage-inducible transcription factor 4(DDIT4)in predicting lymph node metastasis and prognosis of patients with endometrial cancer.Methods A total of 180 cases of endometrial cancer patients treated in Tangshan Maternal and Child Health Hospital from October 2019 to October 2021 were selected as endometrial cancer group.In addition,180 patients with benign uterine diseases treated in this hospital during the same period were selected as the benign disease group,and 180 healthy patients who underwent physical examination in this hospital were selected as the healthy group.The endometrial cancer group was divided into 42 cases with lymph node metastasis and 138 cases without lymph node metastasis according to whether lymph node metastasis occurred.The patients were divided into poor prognosis group and good prognosis group according to the follow-up results.The levels of serum PKN1,TNFRSF4 and DD1T4 in each group were compared,the influencing factors of patient prognosis were analyzed by Logistic model,and the predictive value of serum PKN1,TNFRSF4 and DDIT4 on prognosis of patients was analyzed by drawing the receiver operating characteristic curve.Results Compared with the healthy group,the levels of serum PKN1 and DDIT4 in endometrial cancer group and benign disease group were in-creased,and the levels of serum TNFRSF4 were decreased,with statistical significance(P＜0.05).The serum levels of PKN1 and DDIT4 in lymph node metastasis group were higher than those in no lymph node metasta-sis group,and the levels of TNFRSF4 were lower than those in no lymph node metastasis group,with statisti-cal significance(P＜0.05).The proportion of poor prognosis group with low differentiation degree,positive lymphovascular space invasion and myometrial infiltration≥1/2 was higher than that of good prognosis group,and the difference was statistically significant(P＜0.05).The levels of serum PKN1 and DDIT4 in the poor prognosis group were higher than those in the good prognosis group,and the levels of TNFRSF4 were lower than those in the good prognosis group,with statistical significance(P＜0.05).Serum PKN1,DDIT4,LVSI and myometrial infiltration were risk factors for the prognosis of endometrial cancer,and serum TN-FRSF4 was protective factor for the prognosis of endometrial cancer(P＜0.05).Serum PKN1,TNFRSF4 and DDIT4 combined predicted the prognosis of patients with endometrial cancer more effectively than each serum index alone(P＜0.05).Conclusion Serum PKN1,TNFRSF4 and DDIT4 are related to lymph node metasta-sis and prognosis of patients with endometrial cancer,and have high predictive efficacy for patient prognosis.

Objective To design a storage device for lymph node specimens of gynecological malignant tumors and to evaluate its application effect.Methods The specimen depository is composed of 3 parts,including storage frame,partition plate and marking plate.391 patients with gynecological malignant tumor surgeries requiring collection of retroperitoneal lymph nodes were selected in the operating room of a tertiary A hospital in Zhejiang Province from January to December 2022 in accordance with the operation schedule.They were randomly divided into an experimental group(n=196)and a control group(n=195).Patients in the experimental group used a newly developed storage device,while the control group was with traditional device.The incidence of additional verification specimens by doctors,the average time for disposing of lymph node specimens,and the job satisfaction survey of doctors and nurses were compared.Results Within a period of 12 months after utilizing this easily recognizable specimen storage device,the additional verification rate in the experimental group was 10.62％compared with the rate of 72.48％in the control group.The average time of disposing lymph node specimens was reduced from(8.3±0.9)to(5.2±0.3)minutes.Doctors and nurses in the experimental group reported a higher level of satisfaction for the specimen storage device(P＜0.05).Conclusion Utilizing the newly designed specimen storage device can help medical staff to alleviate their workload,enhance their work efficiency,raise their job satisfaction,and ensure the accuracy of pathological results.

Objective:To explore clinical value of nucleic acid detection for hepatitis B virus (HBV) screening in hospitalized patients.Methods:This cross-sectional study collected and analyzed plasma samples from patients admitted to 10 domestic medical institutions from July 2021 to December 2021. Serological immunoassay and nucleic acid screening were used to simultaneously detect hepatitis B markers such as hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), hepatitis B e Antigen (HBeAg), hepatitis B e antibody (HBeAb), hepatitis B core antibody (HBcAb),and HBV DNA. Statistical analysis was performed on the serology, nucleic acid test results and clinical information of the patients.Results:Of the 8 655 collected samples, HBsAg was positive in 216 (2.50%) samples,HBV DNA was positive in 238 (2.75%) samples ( P>0.05); 210 (2.43%) samples were positive for both HBsAg and HBV DNA, 28 (0.32%) were HBsAg negative and HBV DNA positive, 6 cases (0.07%) were HBsAg positive and HBV DNA negative. Conclusion:These results indicate that the HBV DNA testing is equally effective as hepatitis B virus serological detection for hepatitis B virus screening in hospitalized patients.
