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 evaluate the safety and feasibility of transumbilical single-port transabdominal preperitoneal hernioplasty plus cholecystectomy (SILS-TAPP+LC).Methods:The clinical data of 52 adult patients who underwent [SILS-(TAPP+LC)] from Mar, 2019 to Oct, 2021 at the Affiliated Hospital of Nantong University were retrospectively analyzed.The perioperative indicators, postoperative complications and follow-up data were analyzed.Results:All operations were successfully completed without conversion to open or multi-port laparoscopic surgery.The duration of surgery was (49.2 ± 7.5) min. Three patients experienced gallbladder rupture, and there was no bladder or intestinal injury during the surgery.During the 20-24 months of postoperative follow-up period,4 patient developed seroma in the postoperative period, 4 patients complained foreign body sense in the inguinal region, 3 patients reported chronic pain, but no other complications, such as biliary fistula, recurrence, mesh infection, or trocar hernia, were observed.Conclusion:SILS-(TAPP+LC) was a safe and feasible approach associated with little postoperative pain and rapid recovery.

Objective To evaluate the predictive values of serum neutrophil gelatinase-associated lipocalin (NGAL), urine NGAL, serum cystatin C (Cys-C) and serum creatinine (Scr) for early delayed graft function (DGF) in kidney transplant recipients. Methods Clinical data, blood and urine samples of 159 kidney transplant recipients were collected. All recipients were divided into the DGF group (n=42) and immediate graft function (IGF) group (n=117) according to the incidence of DGF. Clinical data of all recipients were analyzed. The changes of serum NGAL, urine NGAL, Cys-C and Scr levels were statistically compared between two groups. The predictive values of different markers for early DGF were assessed. Results Among 159 kidney transplant recipients, DGF occurred in 42 cases with an incidence rate of 26.4%. There were statistically significant differences in donor age, cold ischemia time of donor kidney and complement-dependent cytoxicity (CDC) between the two groups(all P < 0.05). Within postoperative 2 weeks, the serum NGAL levels in the DGF group were higher than those in the IGF group (all P < 0.05). The Cys-C, Scr and urine NGAL levels in the DGF group were higher compared with those in the IGF group within 3 weeks after kidney transplantation(all P < 0.001). Serum NGAL, urine NGAL, Cys-C and Scr levels had certain predictive values for early DGF in kidney transplant recipients. Cys-C yielded the highest predictive value with a cut-off value of 4.73 mg/L, sensitivity of 0.833, specificity of 0.812 and area under the curve (AUC) of 0.895. Conclusions Cys-C has higher predictive value for early DGF in kidney transplant recipients compared with serum NGAL, urine NGAL and Scr.

Objective:To investigate the morphological characteristics of skull base in children with hemifacial microsomia (HFM) by three-dimensional reconstruction and measurement of skull base.Methods:Three-dimensional spiral CT data of HFM children with unilateral involvement who had not received any treatment from the First Center of Maxillofacial Plastic Surgery, Plastic Surgery Hospital of the Chinese Academy of Medical Sciences from February 2010 to December 2020 were collected. The patients were divided into four groups according to the Pruzansky-Kaban classification standard: Ⅰ, Ⅱa, Ⅱb and Ⅲ. The three-dimensional reconstruction and measurement of the skull base were performed using Mimics 17.0 software. Linear measurements of the skull base included the distance from tuberculum sellae to optic canal (OT), foramen rotundum (FrT), foramen ovale (FT), internal acoustic meatus (IT), hypoglossal canal (HT), and the distance from anterior clinoid process to the lesser wing of the sphenoid bone (ClS) and the petrous ridge of the temporal bone (ClP). The measurement indexes of skull base angle included anterior cranial angle (ACA), middle cranial angle (MCA), posterior cranial angle (PCA), and petrous ridge angle (PRA). SPSS 26.0 software was used for statistical analysis of the measurement result. Paired t-test was used for comparison within each group, and one-way ANOVA was used for comparison between different types. P<0.05 was statistically significant. Results:A total of 40 children with HFM were collected, with 10 cases in each group. The result of skull base angle measurement showed that the MCA of the healthy side of typeⅠHFM was significantly larger than that of the affected side, and the MCA and PRA of the healthy side of type Ⅲ HFM were larger than those of the affected side ( P<0.05). There was no significant difference in the angle of skull base between the healthy side and the affected side of typeⅡa andⅡb HFM ( P>0.05). In terms of linear distance measurement of skull base, FrT and HT on the healthy side of typeⅠHFM were longer than those on the affected side; FrT, IT, HT and ClP on the healthy side of typeⅡa HFM were significantly longer than those on the affected side; IT, HT and ClP on the healthy side of typeⅡb HFM were longer than those on the affected side; and HT on the healthy side of type Ⅲ HFM was longer than those on the affected side ( P<0.05). The difference between FrT and ClP (affected / healthy) of four types of HFM was statistically significant ( P<0.05). Conclusions:The morphology of HFM is different between the affected side and the healthy side. As for the angle of skull base, MCA was obvious smaller in the affected side than that in the healthy side in the type Ⅰ and type Ⅲ HFM. As for the linear measurement, the distance from the hypoglossal canal to the tuberculum sellae on the affected side is shorter than that on the healthy side in each type HFM, indicating that the growth and development of the cranial base on the affected side is affected in a certain degree.

Objective:To analyze the clinical and chest CT features in a family with interstitial lung disease(ILD), and assess the probable causative gene mutations for the family.Methods:In order to identify the etiology of the proband′s ILD, the pedigree was investigated.The clinical data of five proband′s pedigree members were collected, and the chest HRCT examination was performed on four proband′s pedigree members with respiratory symptoms.The human whole exon sequencing was performed on the proband′s blood samples, then its deleterious effects were assessed.Subsequently, the strong pathogenic mutation was validated by Sanger sequencing.Results:According to the family survey, there were five patients with ILD in the family, including three males and two females.One of them died.The surfactant protein C(SFTPC)gene(exon4, c.342G>T, p.K114N)was found in all four surviving patients.The mutation was considered to be originated from the father of the proband, and the pathogenic mutation was considered, which was not included in the databases and was a noval mutation.In addition, the clinical manifestations of different patients in the family were significantly different.Conclusion:The novel mutation of p. k114n in SFTPC gene can lead to ILD in children, and the mutation has incomplete exons in family members.Chest CT and whole exon sequencing play an important role in the diagnosis of ILD in children.

Objective To study and analyze the risk factors in children with type 1 diabetes and formulate preventive health measures. Methods A total of 112 children with type 1 diabetes treated in our hospital from January 2017 to October 2019 were selected as the type 1 diabetes group, and 50 healthy children who underwent physical examination during the same period were selected as the control group. Multifactor logistic regression analysis was used to analyze predisposing factors of type 1 diabetes in children, and preventive health measures was proposed. Results The results of multivariate logistic regression analysis indicated that maternal age, passive smoking during pregnancy, milk feeding time, and children's respiratory infections were independent risk factors for children with type 1 diabetes (OR: 6404, 6.903, 6.417, 8.256, P <0.05). Conclusion Maternal age, passive smoking during pregnancy, milk addition time, and children's respiratory infections were independent risk factors for children with type 1 diabetes. Strengthening health education, breastfeeding as soon as possible, and preventing respiratory infections can help reduce the incidence of children with type 1 diabetes.

OBJECTIVE: To analyze the clinical and genetic characteristics in a girl with 2q37 deletion syndrome. METHODS: Genomic DNA was extracted from peripheral blood samples taken from the patient and her parents, and was subjected to whole exome sequencing (WES) and low-coverage massively parallel copy number variation sequencing (CNV-seq). Candidate CNVs were verified by chromosomal karyotyping analysis and fluorescence quantitative PCR. RESULTS: The child was found to harbor a 6 Mb heterozygous deletion in 2q37 by WES and CNV-seq. The deletion has encompassed 98 genes with a range from GBX2 to LINC01881, and was de novo in origin. The result of fluorescence quantitative PCR was consistent with that of WES and CNV-seq. However, karyotyping analysis has failed to detect the deletion. CONCLUSION The patient was diagnosed with 2q37 deletion syndrome. Combined WES and CNV-seq method features high resolution, high throughput, and high sensitivity, which can significant raise the diagnostic rate for patients with mental disorder, multiple malformations and unknown syndromes.

BACKGROUND: Bronchial sleeve lobectomy is essential surgical approach to treat centralized lung cancer. It is the best reflected the principle of lung cancer surgery, "remove tumor completely while minimize pulmonary function loss". Bronchial pleural fistula (BPF) is not common but very severe complication of bronchial sleeve lobectomy, that is usually fatal. Present article is to explore clinical effect on prevention of bronchial pleural fistula (BPF) in bronchial sleeve lobectomy, by wrapping brachial anastomosis with pedicled pericardial fat flap. METHODS: Clinical data of 39 non-small cell lung cancer (NSCLC) patients who underwent surgical resection during January 2016 to May 2019 in Lung Cancer Center of West China Hospital, Sichuan University were collected and retrospectively analyzed. All of the patients underwent bronchial sleeve lobectomy and a brachial anastomosis wrapping with pedicled pericardial fat flap. RESULTS: All patients recovered well and were discharged within 6 d-14 d after operation. No BPF occurred, nor other severe complications, such as reoperation needing intrathoracic bleeding, several pneumonia and respiratory failure, and life threatening cardiac arrhythmia. Only one patient (1/39) had several anastomotic stenosis and consequential atelectasis of residual lung in operative side 6 months after surgery. CONCLUSIONS Wrapping bronchial anastomosis with pedicled pericardial fat flap in bronchial lobectomy for centralized NSCLC is a simple and effective approach to prevent BPF, thus safety of the operation could be significantly improved.

Objective: To investigate the expression of long non-coding RNA (lncRNA)H19 in gallbladder cancer and its relationship with clinicopathological parameters and prognosis. Methods: 74 cases of allbladder cancer resected in our hospital were collected and studied. At the same time, 66 cases of benign gallbladder lesions were selected as benign lesion group. The expression of lncRNA H19 in tissues was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). The correlation between lncRNA H19 expression and clinicopathological parameters of gallbladder cancer patients was analyzed.The patients were followed up for 3 years and COX was used to analyze the prognostic factors affecting the survival rate.The survival was analyzed by Kaplan-Meier curve. The survival differences of lncRNA H19 expression groups were detected by Log-Rank method. Results: The expression level of lncRNA H19 in gallbladder cancer was significantly higher than that in benign lesions (P<0.05). The expression of lncRNA H19 was correlated with stage, differentiation and lymph node metastasis (P<0.05). Age, sex, histological grade, stage and depth of invasion of gallbladder cancer had no significant correlation with 3-year survival rate (P>0.05). The survival rate of patients with differentiated tumors and non-metastatic lymph nodes were higher (P<0.05). The survival rate of patients with low expression of lncRNA H19 was significantly higher than those with high expression of lncRNA H19 (P<0.05). Tumor differentiation, lymph node metastasis and lncRNA H19 expression were independent risk factors affecting the prognosis of patients with gallbladder cancer. Conclusions LncRNA H19 is highly expressed in gallbladder cancer, which is closely related to the degree of differentiation, lymph node metastasis and survival rate of patients.
