Objective To investigate the feasibility of translocation of pedicled buccal fat pad in the treatment of the temporomandibular joint ankylosis(TMJA)by measuring the diameter of buccal fat pad and related anatomical structures of the transverse blood vessels,nerves and temporomandibular joint.Methods A total of 40 adult head and neck specimens were randomly divided into group A and group B,with 20 cases in each group.The morphology of the buccal fat pad in group A was observed,and its size and compression diameter through blood vessels and nerves were measured.The anatomical structures of the temporomandibular joint in group B were observed and measured.Results The volume of buccal fat pad in group A was(10.10±1.10)mL on the left side and(9.70±1.50)mL on the right side.The longitudinal axis length of buccal fat pad was(28.18±1.35)mm on the left side and(29.47±1.12)mm on the right side;Transverse axis length of buccal fat pad was(18.56±1.67)mm on the left side and(18.97±1.73)mm on the right side;There are facial artery,facial vein,maxillary artery branch,facial nerve buccal branch and so on through the buccal fat pad.In group B,the sagittal section of the temporomandibular joint disc presented S-type in 15 cases(75.0%),L-type in 3 cases(15.0%),and transitional type in 2 cases(10.0%).Anterior and posterior diameter of the articular disc was(14.42±1.94)mm on the left side and(15.34±1.37)mm on the right side;inside and outside diameter of the articular disc was(20.18±1.77)mm on the left side and(19.57±1.32)mm on the right side.Branches of maxillary artery and superficial temporal artery were respectively distributed within and outside the joint.Conclusion The pedicled buccal fat pad has a constant anatomical position,abundant blood supply,strong tissue repair,anti-infection ability and"buffer pad"function,which can reduce the formation of scar after surgery for TMJA,reduce the postoperative recurrence rate,and contribute to the recovery of joint function after surgery.

Purpose::The reconstruction of Allen's type IV fingertip amputation is a clinical challenge. Our team designed bilateral unequal-sized hallux osteo-onychocutaneous free flaps for the long-term reconstruction of Allen's type IV fingertip amputation and conducted a retrospective study with a 5-year follow-up aims to evaluate the effects of this technique.Methods::A retrospective analysis with a 5-year follow-up including 13 patients with Allen's type IV fingertip amputation who were admitted to our hospital from January 2010 to January 2017 was conducted. The patients were treated with bilateral unequal-sized hallux osteo-onychocutaneous free flaps. The operation time, intraoperative blood loss, and complications were recorded, and the survival rate of the transplanted flaps was calculated. During the 5-year follow-up after operation, the nail growth time was recorded and the finger appearance was observed. At the last follow-up appointment, the length, width, and girth of the reconstructed fingertip and contralateral normal fingertip, range of motion of the reconstructed fingertip and contralateral normal fingertip, Semmes-Weinstein test (for the evaluation of tactile sensation), and two-point discrimination testing results were recorded. SPSS 22.0 software was used for the statistical analysis and the data are presented as mean ± SD.Results::The mean operation time was (5.62 ± 0.51) h, the mean intraoperative blood loss was (34.15 ± 3.13) mL, and the survival rate of the transplanted flaps was 100%. During the 5-year follow-up, the average nail growth time was (10.14 ± 1.98) months and the average bone union time was (3.78 ± 0.91) months. The length, width, and girth of the reconstructed fingertip were (31.52 ± 3.73) mm, (17.82 ± 1.74) mm, and (59.75 ± 3.04) mm, respectively, which did not differ from those of the contralateral normal fingertip. The range of motion of the reconstructed fingertip was (12.15 ± 2.79) degrees which is different from that of the contralateral normal fingertip. The average tactile sensation evaluated via the Semmes-Weinstein test and the average two-point discrimination test of the reconstructed fingertip were (0.39 ± 0.17) g and (7.46 ± 1.14) mm, respectively, which were not different from those of the contralateral normal fingertip. The average Maryland score of feet in the donor area was 87.66 ± 7.39, which was satisfactory.Conclusion::Bilateral unequal-sized hallux osteo-onychocutaneous free flaps are an effective method to reconstruct Allen's type IV fingertip amputations with a satisfactory appearance and good sensory function.

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 compare the clinical efficacy of the H-Loop knotless double-row technique and the suture bridge technique in repairing L-shaped rotator cuff tears under arthroscopy.Methods:A retrospective analysis was performed on 58 patients with L-shaped rotator cuff injuries who underwent arthroscopic repair at Sun Yat-sen Memorial Hospital, Sun Yat-sen University, between January 2019 and December 2021. The H-Loop knotless double-row technique was used in 16 cases (8 males and 8 females, mean age 63.69±8.78 years), while the suture bridge technique was used in 42 cases (24 males and 18 females, mean age 61.02±7.02 years). The American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles Shoulder Score (UCLA), Simple Shoulder Test (SST), shoulder range of motion, and muscle strength were evaluated and compared between the two groups one year after surgery.Results:The follow-up period was 12.81±0.98 months for the H-Loop group and 13.29±0.94 months for the suture bridge group. No significant differences were found between the groups in terms of age, sex, dominant hand, preoperative symptom duration, tear shape, tear size, or long head tendon amputation (P>0.05). The operative time was significantly shorter in the H-Loop group 67.50±16.02 minutes compared to the suture bridge group 76.67±13.19 minutes ( t=2.234, P=0.031). Additionally, the number of anchors used was significantly lower in the H-Loop group 2.00±0 compared to the suture bridge group 4.14±0.35 ( t=16.573, P<0.001). The ASES scores increased significantly in both groups: from 57.44±15.91 to 92.00±4.41 in the H-Loop group and from 58.21±16.58 to 87.71±6.19 in the suture bridge group ( F=53.439, P<0.001; F=72.511, P<0.001). Similarly, the UCLA scores improved from 20.63±3.79 to 31.56±3.65 in the H-Loop group and from 20.83±5.78 to 30.36±4.71 in the suture bridge group ( F=57.788, P<0.001; F=50.043, P<0.001). The Constant-Murley scores also showed significant improvement: from 68.50±15.31 to 87.5±8.70 in the H-Loop group and from 66.21±16.51 to 86.33±9.14 in the suture bridge group ( F=6.733, P<0.001; F=30.173, P<0.001). SST scores increased from 6.38±3.76 to 9.06±2.59 in the H-Loop group and from 6.55±3.31 to 9.17±2.45 in the suture bridge group ( F=2.847, P<0.001; F=11.096, P<0.001). The shoulder flexion range of motion increased from 158.75°±21.25° to 178.75°±47.07° in the H-Loop group and from 139.29°±45.12° to 179.76°±3.42° in the suture bridge group ( t=3.814, P=0.002; t=5.877, P<0.001). Shoulder abduction motion increased from 145°±45.46° to 178.75°±3.42° in the H-Loop group and from 135.24°±47.07° to 179.76°±1.54° in the suture bridge group ( t=2.952, P=0.001; t=6.185, P<0.001). Muscle strength improved from 53.36±25.21 N to 73.69±24.09 N in the H-Loop group and from 43.31±24.49 N to 61.8±30.07 N in the suture bridge group ( t=4.916, P<0.001; t=5.623, P<0.001). The ASES score at one year post-surgery was significantly higher in the H-Loop group 92.00±4.41 compared to the suture bridge group 87.71±6.19 ( t=2.529, P=0.014). There were no significant differences in UCLA scores, Constant-Murley scores, SST scores, shoulder motion, or muscle strength between the groups ( P>0.05). Conclusion:The H-Loop technique provides a good early curative effect. Compared to the traditional suture bridge technique, the H-Loop technique offers a higher early postoperative ASES score, shorter operative time, and fewer anchors required.

Purpose: Protective ileostomy and colostomy are performed in patients undergoing low anterior resection with a high leakage risk. We aimed to compare surgical, medical, and daily care complications between these 2 ostomies in order to make individual choice. Methods: Patients who underwent low anterior resection for rectal tumors with protective stomas between January 2011 and September 2018 were enrolled. Stoma-related complications were prospectively recorded by wound, ostomy, and continence nurses. The cancer stage and treatment data were obtained from the Taiwan Cancer Database of our Big Data Center. Other demographic data were collected retrospectively from medical notes. The complications after stoma creation and after the stoma reversal were compared. Results: There were 176 patients with protective colostomy and 234 with protective ileostomy. Protective ileostomy had higher proportions of high output from the stoma for 2 consecutive days than protective colostomy (11.1% vs. 0%, P<0.001). Protective colostomy resulted in more stoma retraction than protective ileostomy (21.6% vs. 9.4%, P=0.001). Female, open operation, ileostomy, and carrying stoma more than 4 months were also significantly associated with a higher risk of stoma-related complications during diversion. For stoma retraction, the multivariate analysis revealed that female (odds ratio [OR], 4.00; 95% confidence interval [CI], 2.13–7.69; P<0.001) and long diversion duration (≥4 months; OR, 2.33; 95% CI, 1.22–4.43; P=0.010) were independent risk factors, but ileostomy was an independent favorable factor (OR, 0.40; 95% CI, 0.22–0.72; P=0.003). The incidence of complication after stoma reversal did not differ between colostomy group and ileostomy group (24.3% vs. 20.9%, P=0.542). Conclusion We suggest avoiding colostomy in patients who are female and potential prolonged diversion when stoma retraction is a concern. Otherwise, ileostomy should be avoided for patients with impaired renal function. Wise selection and flexibility are more important than using one type of stoma routinely.

Metabolic dysfunction-associated fatty liver disease (MAFLD) is an increasingly common liver disease worldwide. MAFLD is diagnosed based on the presence of steatosis on images, histological findings, or serum marker levels as well as the presence of at least one of the three metabolic features: overweight/obesity, type 2 diabetes mellitus, and metabolic risk factors. MAFLD is not only a liver disease but also a factor contributing to or related to cardiovascular diseases (CVD), which is the major etiology responsible for morbidity and mortality in patients with MAFLD. Hence, understanding the association between MAFLD and CVD, surveillance and risk stratification of MAFLD in patients with CVD, and assessment of the current status of MAFLD management are urgent requirements for both hepatologists and cardiologists. This Taiwan position statement reviews the literature and provides suggestions regarding the epidemiology, etiology, risk factors, risk stratification, nonpharmacological interventions, and potential drug treatments of MAFLD, focusing on its association with CVD.
