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.

In the surgical treatment of hemorrhoids, rectal prolapse, rectal cancer, anal fissures, or anal fistulas, inadvertent damage to the nerves or muscles responsible for bowel control may potentially lead to varying degrees of fecal incontinence (FI). Surgeons need to conduct preoperative assessments based on the patient's individual condition to select an appropriate surgical plan, aiming to minimize the incidence of postoperative FI and improve the patient's postoperative quality of life as much as possible while effectively treating the disease. Additionally, the proficiency of the surgeon's skills, appropriate preoperative dietary adjustments for the patient, regular bowel habits, and exercises targeting the pelvic floor muscles all contribute to reducing the incidence of postoperative FI in patients. For patients who have already developed FI after surgery, on the basis of suitable diet, regular bowel habits, and medication, clinical practitioners can adopt such methods as biofeedback, pelvic floor muscle exercise, sacral nerve stimulation, percutaneous tibial nerve stimulation, acupuncture, injectable bulking agents, anal or vaginal inserts, transanal irrigation, surgical interventions, psychological support, etc., to individualized treatment for patients' conditions. This article, combining the literature, summarizes the current status of common diseases that may lead to postoperative FI. It elaborates on strategies for the prevention and treatment of postoperative FI, aiming to serve as a reference for peers in the field.

Statistics show that 76.74% (4 688) of 6 109 patients with chronic wounds are those over 50 years of age; the proportion of patients with underlying diseases in all age groups above 50 years ranges from 78.25% to 100.00%; among the underlying diseases of chronic wound patients, the top four diseases are diabetes mellitus , cardiovascular and cerebrovascular diseases, hypertension, and respiratory diseases. The above underlying diseases and ages of patients are the susceptibility factors of corona virus disease 2019 released by National Health Commission of China. It is an unavoidable fact that patients with chronic wounds have to go to the hospital for treatment prescribed by the physician. At the same time, we found that there were not a few patients who go far afield because of various reasons when go to the hospital for treatment. During the period of epidemic prevention and control, this kind of "go far afield" style of seeking medical treatment may increase the exposure risk during transportation. Accordingly, we convened 36 wound care clinics in different regions in Shanghai to implement the "Five Measures" to encourage patients with chronic wounds to seek medical treatment proximately. The principle of this operation is that when seeking medical treatment, trying our best to reduce as much as possible the transportation distance for patients with chronic wounds to minimize the exposure risk during the epidemic period and eventually support the epidemic prevention and control campaign.

The clinicopathological features of 5 cases of micropapillary pattern of pure mucinous carcinoma (MPPPMC) of the breast were analyzed retrospectively. In this group, 5 cases of MPPPMC were all premenopausal women, whose age ranged from 37 to 48 years old. 3 cases had axillary lymph node metastasis, 3 cases had modified radical mastectomy, 1 case had breast conserving and sentinel lymph node biopsy, 1 case had breast conserving and axillary lymph node dissection, 1 case had oral endocrine drug and radiotherapy, 4 cases had oral endocrine drug and chemotherapy and radiotherapy, and 2 cases had oral targeted drug herceptin treatment. MPPPMC pattern is a kind of special type of pure mucinous carcinoma and invasive micropapillary carcinoma. The age of onset of this type is younger than that of mucinous carcinoma, and the prognosis of this type is worse than mucinous carcinoma. Whether it is an independent subtype of breast invasive micropapillary carcinoma or mucinous carcinoma has not reached consensus.

Objective: Exploring the effect of three-flap paltoplasty in preventing anterior palatal fistula for patients whose anterior fissures measured more than 0.5 cm. Methods: 12 patients aged 18-24 months with unilateral complete cleft palate were selected for the implementation of three-flap paltoplasty for cleft palate repair. Briefly, three-flap paltoplasty is based on the traditional two-flap paltoplasty method and involves the creation of a mucoperiosteal flap A in the contralateral palate in front of the fissure margin that is approximately half the size of the anterior palate. The flap A was sutured to the edge of the contralateral nasal mucosa, and the mucoperior flap of both sides of the loose fissure was sutured in layers, and the suture was removed two weeks after surgery. The recovery of cleft palate was observed. Results : All patients were followed up for 3 months, and 12 patients underwent successful repairs with no fistula and other complications. Conclusion Three-flap paltoplasty is an effective method of preventing anterior palatal fistula.

BACKGROUND:Alveolar distraction osteogenesis is an important method for treating alveolar bone atrophy, the osteogenesis process and biomechanics play a crucial role in the fol owing implantation and repair. At present, no related experimental studies are found.
OBJECTIVE:To analyze the biomechanical and histological characteristics of alveolar distraction osteogenesis in a canine model.
METHODS:Twelve adult mongrel canines received premolars extraction and alveoloplasty in mandible to establish an atrophy alveolar model. After 3 months, a segmental alveolar osteotomy was performed in the randomly selected unilateral atrophy alveolar and two intra-osseous distractors were placed. After a 7-days latency period, the alveolar ridge was augmented at a rate of 1.0 mm/d for 5 days. After a consolidation of 1, 2, and 3 months, the canines were sacrificed and the specimens of the distracted alveolar bone were harvested for clinical, radiographic, histological and biomechanical analysis.
RESULTS AND CONCLUSION:The alveolar distractors obtained good healing with surrounding tissue. The atrophy alveolar bones were augmented for (4.80±0.50) mm and (5.12±0.47) mm by clinical and radiographic findings immediately after distraction, respectively. The bone trabeculae in the distracted chamber matured from 1 to 3 months of consolidation by histological analysis. The shearing force of alveolar distraction chamber increased from 1 to 3 months. After 3 months’ consolidation, the shearing force of distracted chamber was comparable to host bone. The histological and biomechanical property of distracted alveolar chamber is comparable to host bone after 3 months’ consolidation.
