【Objective】 To investigate the condition of confidential unit exclusion(CUE) in Guangzhou, so as to ensure blood safety. 【Methods】 The number of CUE donors, demographic characteristics of CUE donors, reasons for CUE, and response time of CUE after blood donation in Guangzhou from 2009 to 2022 were statistically analyzed. 【Results】 From 2009 to 2022, the response ratios of CUE was 0.006 2% (260/4 170 984) and the ratios had statistically significant difference between different years(P<0.05). For the response ratios of CUE, no statistically significant difference was noticed in gender and occupation (P>0.05), but statistically significant differences were found in age, number of blood donations, education background, and marital status (P<0.05). Blood donors aged 18~30 (0.007 3%, P<0.05) and first-time blood donors (0.010 8%, P<0.05) were the main groups of CUE. High risk sexual behavior (28.46%, 74/260) was the primary reason for CUE. The CUE response peak was within 72 hours after blood donation, and the response ratios within 24-72 hours after blood donation was the highest (68.46%, 178/260). 【Conclusion】 CUE is a crucial measure to ensure blood safety. Detailed pre-donation health consultations are suggested for blood donors aged 18-30 and first-time blood donors so as to better excluding high-risk blood donors. Strengthening the publicity of CUE response and process, registering and classifying the reasons for CUE are also important.

The discarding rate in 2023 was lower than that in 2022 (0.54%, 2 868/534 854 U) vs (0.60%, 3 047/510 698 U) (P<0.01), and the non-test unqualified discarding rate (lipemic blood excluded) in 2023 was significantly lower than that in 2022(0.12%, 649/534 854 U) vs (0.19%, 991/510 698 U)(P<0.01). 【Conclusion】 The construction of supervision and management system of a whole business process based on blood bank management information system can meet the standardized service needs of managers at anytime and anywhere, continuously raise productivity and the standardization and scientific level of blood bank management, thus ensuring blood supply.

BACKGROUND:Cell derivative is cell-derived bioactive components,including decellularized extracellular matrix,exosome,apoptotic extracellular vesicle,and conditioned medium,has the effects on immune regulation,promoting angiogenesis,bone regeneration,ligament remodeling,and is capable of promoting stem cell chemotherapy,migration,proliferation,and adhesion.Its excellent characteristics make it a promising biomaterial for application and clinical translation in the field of periodontal tissue engineering. OBJECTIVE:To review the characteristics of cell derivatives(decellularized extracellular matrix,exosome,apoptotic extracellular vesicle,and conditioned medium)and its effect and the latest progress in the field of regenerative restoration of periodontal complex tissue structures. METHODS:We searched the articles on CNKI and PubMed databases with the search terms"regeneration,periodontal tissue,tissue engineering,decellularized matrix,exosome,apoptotic extracellular vesicle,condition medium"in Chinese and English,respectively.Finally,76 articles were included for analysis and discussion. RESULTS AND CONCLUSION:(1)Among those four cell derivatives,the decellularized extracellular matrix has the best mechanical properties and fibrous structure,serving as a biomimetic scaffold to provide physiochemical signals and participate in mechanical signaling in periodontal tissue engineering,providing supporting effect suitable for periodontal regeneration.Recently,the development of soluble decellularized extracellular matrix bioinks has enabled the fabrication of regenerative scaffolds for personalized periodontal defects.(2)Exosomes are the simplest cell derivatives that have immunomodulatory capacity,promoting cell migration and differentiation.As a carrier,they can be used to carry target molecules to regulate periodontal regeneration,promote ligament remodeling and bone regeneration,and are suitable for periodontal tissue engineering.(3)Apoptotic vesicles generated from apoptotic cells have a strong immunomodulatory effect and can recruit stem cells and macrophages,which determine the fate of stem cells through signal transduction and can enhance immunomodulation to promote periodontal regeneration.Engineered extracellular vesicle is considered to have the potential to initiate targeted internal immunomodulation.(4)The extraction of conditioned medium is simple and completely noninvasive,which provides essential nutrients and growth factors for tissue regeneration.These components are crucial for successful periodontal regeneration.Therefore,the conditioned medium is especially suitable for studying the interactions between cells in vitro and has an important role in high-throughput detection in the future.

BACKGROUND:Several studies have found that the total flavonoids of rhizome drynariae can promote neovascularization in the induced membrane,improve the biological properties of the induced membrane,and accelerate bone remodeling in the induced membrane,but the related molecular mechanisms still need to be further explored. OBJECTIVE:To explore the effect of total flavonoids of rhizome drynariae on bone remodeling in rat femoral Masquelet-induced membrane model by regulating H-type blood vessels. METHODS:Thirty-six male Sprague-Dawley rats were stratified by body mass and then randomly divided into blank group,model group and traditional Chinese medicine group,with 12 rats in each group.A 4-mm femoral bone defect model was established in all the rats.Bone defects in the model group and traditional Chinese medicine group were filled with polymethylmethacrylate bone cement.At 6 weeks after modeling,the tail bone of the rats was implanted in the blank group,as well as in the other two groups after removal of bone cement.The traditional Chinese medicine group was given 157.5 mg/kg per day of total flavonoids of rhizome drynariae at 3 days after bone implantation,while the model and blank groups were given the same amount of saline by gavage until the 8th week after bone implantation.Bone graft samples were taken for relevant testing at 8 weeks after implantation. RESULTS AND CONCLUSION:X-ray films showed that in the blank group,the fracture line in the defect area was clear,and only a small amount of bone callus formed;in the model group,the bone defect area still existed,where discontinuous cortical bone was visible;in the traditional Chinese medicine group,the defect area was filled with newborn bone tissues,the bone marrow cavity and part of the cortical bone formed,and the fracture line disappeared.Micro-CT scans showed that the amount of new bone in the defect area was low in the blank group,the number of bone trabeculae in the defect area was significantly increased in the model group,and a large amount of new bone tissue was filled in the bone defect area in the traditional Chinese medicine group.Hematoxylin-eosin staining results showed that in the blank group,only a small amount of new bone formed in the defect area and the quality of osteogenesis was poor;in the model group,there was more new bone tissue in the defect area,but some fibrous connective tissues were interspersed within the bone tissue;and in the traditional Chinese medicine group,a large amount of new bone formed in the defect area and the quality of osteogenesis was the best.CD31/Emcn immunofluorescence double-labeling staining results showed that the number of H-type blood vessels in the newborn bone tissue in the bone defect area of the blank group was sparse and sparsely distributed;compared with the blank group,there were more H-type blood vessels in the bone tissue in the bone defect area of the model group,and the blood vessels were distributed in relatively regular strips;the number of H-type blood vessels in the bone defect area of the traditional Chinese medicine group was the highest and the blood vessels were densely distributed.To conclude,the total flavonoids of rhizoma drynariae can upregulate the expression of H-type blood vessels to enhance the angiogenic-osteogenic effect,improve the osteogenic efficiency of the rat femoral Masquelet induced membrane model,and promote bone remodeling.

Objective:To investigate the clinical effect of the modified vertical rectus abdominis myocutaneous flap in repairing the skin and soft tissue defect after abdominoperineal resection for rectal cancer.Methods:This study was a retrospective observational study. From June 2019 to July 2022, five male patients with low rectal cancer who were conformed to the inclusion criteria were admitted to the Department of Basic Surgery of Xiangya Hospital of Central South University, with ages ranging from 65 to 70 years and the sizes of the perianal skin ulcers ranging from 5 cm×4 cm to 11 cm×9 cm, and all of them underwent abdominoperineal resection. The secondary skin and soft tissue defects in the perineum with an area of 8 cm×6 cm-14 cm×12 cm (with the depth of pelvic floor dead space being 10-15 cm) were repaired intraoperatively with transplantation of modified vertical rectus abdominis myocutaneous flaps with the skin area being 9 cm×7 cm-16 cm×12 cm, the volume of the muscle being 18 cm×10 cm×5 cm-20 cm×12 cm×5 cm, and the vessel pedicle being 18-20 cm in length. During the operation, most of the anterior sheath of the rectus abdominis muscle was retained, the flap was transferred to the recipient area through the abdominal cavity, the remaining anterior sheaths of the rectus abdominis muscle on both sides of the donor area were repeatedly folded and sutured, the free edge of the transverse fascia of the abdomen was sutured with the anterior sheath of the rectus abdominis muscle, and the donor area skin was directly sutured. After the operation, the survival of the transplanted myocutaneous flap was observed. The occurrence of complications in the perineal recipient area was recorded within 2 weeks after the operation. The recovery of the perineal recipient area and the abdominal donor area was observed during follow-up, and the occurrence of complications in the donor area of the abdomen as well as the recurrence of tumors and metastasis were recorded.Results:All transplanted myocutaneous flaps in 5 patients survived after surgery. One patient had dehiscence of the incision in the perineal recipient area 2 days after surgery, which healed after 7 d with intermittent dressing changes and routine vacuum sealing drainage treatment. In the other 4 patients, no complications such as incisional rupture, incisional infection, or fat liquefaction occurred in the perineal recipient area within 2 weeks after surgery. Follow-up for 6-12 months after discharge showed that the skin of the perineal recipient area had good color, texture, and elasticity, and was not bloated in appearance; linear scars were left in the perineal recipient area and the abdominal donor area without obvious scar hyperplasia or hyperpigmentation; no complications such as incisional rupture, incisional infection, intestinal adhesion, intestinal obstruction, or weakening of the abdominal wall strength occurred in the abdominal donor area, and the abdominal appearance was good with no localized bulge or formation of abdominal hernia; there was no local recurrence of tumor or metastasis in any patient.Conclusions:The surgical approach of using the modified vertical rectus abdominis myocutaneous flap to repair the skin and soft tissue defects after abdominoperineal resection for rectal cancer is relatively simple in operation, can achieve good postoperative appearances of the donor and recipient areas with few complications, and is worthy of clinical promotion.

Objective:To investigate the effects of aloperine(ALO)on cell behavior of colorectal cancer(CRC)cells through IL-6/tyrosine kinase 1(JAK1)/signal transducer and activator of transcription 3(STAT3)pathway.Methods:SW480 cells were grouped into CK group(normal culture of SW480 cells),ALO low-dose group(ALO-L group,0.2 mmol/L),ALO medium-dose group(ALO-M group,0.4 mmol/L),ALO high-dose group(ALO-H group,0.8 mmol/L)and ALO-H+activator(IL-6 activator recombinant human IL-6 protein)group(0.8 mmol/L+100 ng/ml).Proliferation of SW480 cells was detected by CCK-8 and plate cloning experi-ments;apoptosis of SW480 cells was detected by flow cytometry;Western blot was used to detect expressions of proliferating cell nu-clear antigen(PCNA),Bcl-2-associated X protein(Bax),IL-6,p-JAK1,p-STAT3 proteins in cells.After the above five groups of cells were co-cultured with natural killer cells NK-92MI,respectively,they were named as CK co-culture group,ALO-L co-culture group,ALO-M co-culture group,ALO-H co-culture group,and ALO-H+activator co-culture group,respectively.Levels of TNF-α and IFN-γ in supernatant and immune killing rate of NK-92MI in the co-culture system were detected.Results:Compared with CK group,OD450 value,clone formation rate,protein expressions of PCNA,IL-6,p-JAK1,p-STAT3 in SW480 cells in ALO-L group,ALO-M group and ALO-H group were decreased,while apoptosis rate and protein expression of Bax were increased,in a dose-dependent manner(P<0.05);compared with ALO-H group,OD450 value,clone formation rate,protein expressions of PCNA,IL-6,p-JAK1,p-STAT3 in SW480 cells in ALO-H+activator were increased,while apoptosis rate and protein expression of Bax were decreased(P<0.05);compared with CK co-culture group,levels of TNF-α and IFN-γ in supernatant of cells,and the immune killing rate of NK-92MI cells in ALO-L co-culture group,ALO-M co-culture group and ALO-H co-culture group were increased,and in a dose-dependent manner(P<0.05);compared with ALO-H co-culture group,levels of TNF-α and IFN-γ in supernatant of cells,and immune killing rate of NK-92MI cells in ALO-H+activator co-culture group were decreased(P<0.05).Conclusion:ALO may inhibit the proliferation,immune escape and promote apoptosis of SW480 cells by inhibiting IL-6/JAK1/STAT3 signaling pathway.

Objective:To investigate the efficacy of posterior reduction and fixation combined with pedicle subtraction osteotomy (PSO) in the treatment of ankylosing spondylitis (AS) kyphotic deformity complicated by upper cervical spine injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 8 patients with AS kyphotic deformity complicated by upper cervical spine injury, who were admitted to First Affiliated Hospital of Xinjiang Medical University from October 2010 to December 2022.

There were no significant differences in NDI scores at various time points after surgery ( P>0.05). The VAS scores were 2.0(1.0, 3.0)points, 1.5(1.0, 2.0)points, 0.5(0.0, 1.8)points, 0.5(0.0, 1.7)points, and 0.5(0.0, 1.8)points respectively, significantly lower than 3.5(3.0, 4.8)points preoperatively ( P<0.01). The VAS score at 3 months postoperatively was lower than that at 1 week postoperatively ( P<0.05), and the VAS score at 6 months postoperatively was lower than that at 3 months postoperatively ( P<0.05). There were no statistically significant differences in VAS scores at 6, 12 months postoperatively, and at the last follow-up ( P>0.05). There were no statistically significant differences between C 0-C 2 angle and C 1-C 2 angle preoperatively and at different time points postoperatively ( P>0.05). At 1 week and 3, 6, 12 months postoperatively and at the last follow-up, the CL values were -8.5(-5.3, -11.9)°, -8.6(-5.5, -11.9)°, -8.4(5.2, -12.1)°, -8.8(-5.6, -12.4)°, and -8.7(-5.3, -12.5)° respectively, significantly higher than 1.2(9.5, -4.8)° preoperatively ( P<0.01); the HT values were 6.1(4.5, 9.6)°, 6.1(4.3, 9.4)°, 6.0(4.2, 8.9)°, 6.0(4.2, 9.2)°, and 6.1(4.3, 9.2)° respectively, significantly lower than 17.0(10.3, 22.0)° preoperatively ( P<0.01); the CBVA values were (23.2±5.0)°, (23.1±4.8)°, (23.0±4.7)°, (23.1±4.7)°, and (23.1±4.9)° respectively, significantly lower than (44.1±9.8)° preoperatively ( P<0.01); the CSVA values were 5.2(4.2, 7.5)cm, 5.4(4.1, 7.1)cm, 4.7(4.0, 7.4)cm, 5.4(4.1, 7.0)cm, and 5.1(4.3, 6.5)cm respectively, significantly shorter than 9.0(7.8, 9.3)cm preoperatively ( P<0.01); the SVA values were 7.7(6.2, 13.7)cm, 7.5(6.0, 13.4)cm, 7.6(6.2, 13.2)cm, 7.4(6.3, 13.1)cm, and 7.5(6.2, 13.2)cm respectively, significantly shorter than 16.8(8.2, 27.2)cm preoperatively ( P<0.05). There were no statistically significant differences among CL, HT, CBVA, CSVA, and SVA values at different time points after surgery ( P>0.05). All the fractures healed at 12 months after surgery and Bridwell grade I healing was achieved at all the osteotomy sites. At the last follow-up, all the patients were classified as ASIA grade E, significantly improved compared with preoperatively ( P<0.01). One patient had transient C 8 nerve paralysis after surgery and recovered after 4 weeks′ treatment. The remaining patients did not develop any infection or internal fixation-related complications, such as broken rods, broken screws, or loose screws. Conclusion:For AS kyphosis deformity complicated with upper cervical injury, posterior reduction and fixation combined with cervicothoracic or thoracolumbar PSO can effectively promote functional recovery, relieve pain, maintain overall trunk balance, improve neurological symptoms, and reduce the incidence of complications.

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 effectiveness of single posterior osteotomy in the correction of rigid cervical spine deformities (CSD) and to explore the indications and key surgical techniques involved.Methods:A retrospective analysis was conducted on the clinical data of 9 patients with rigid CSD who underwent single posterior osteotomy correction between June 2012 and June 2023 in the Department of Spine Surgery at the First Affiliated Hospital of Xinjiang Medical University. The cohort comprised 4 males and 5 females, with a mean age of 19.8±27.2 years (range, 7-48 years). Among these, 5 cases were congenital CSD, 3 were post-tuberculosis deformities, and 1 was iatrogenic. Various coronal and sagittal alignment parameters were measured, including C 1, 2 angle, cervical lordosis (CL), structural scoliosis angle (SSA), structural kyphosis angle (SKA), head tilt (HT), C 2-C 7 sagittal vertical axis (CSVA), sagittal vertical axis (SVA), coronal balance distance (CBD), T 1 slope (T 1S), and the difference between T 1 tilt and cervical lordosis (T 1S-CL). Clinical outcomes were assessed using the neck disability index (NDI), visual analogue scale (VAS), and Scoliosis Research Society-22 questionnaire (SRS-22). Results:The average operation time was 273.9±76.1 min, with an average blood loss of 472.2±128.8 ml. All 9 patients were followed up for an average of 45.2±41.8 months (range, 12-116 months). A total of 7 patients underwent single-segment osteotomies (C 3, C 6 and C 7: 1 case each; C 5: 4 cases), and 2 patients underwent double-segment osteotomies (C 2 and C 7, C 3 and C 4). Four cases involved pedicle subtraction osteotomy (PSO), while 7 cases required vertebral column resection. The upper instrumented vertebra (UIV) was located at the occiput in 1 case and in the cervical spine in 8 cases. The lower instrumented vertebra (LIV) was located in the upper thoracic spine in 6 cases and in the cervical spine in 3 cases, with 2 of the latter cases having both UIV and LIV in the cervical spine. The average number of fused segments was 7.6±4.4 segments (range, 2-12 segments). All patients achieved successful bone fusion within an average of 8.8±3.2 months (range, 6-12 months). Preoperatively, the mean values for CL, SSA, SKA, HT, and CBD were 19.8° (17.2°, 30.5°), 27.4°(23.3°, 30.4°), 28.4°(25.6°, 30.1°), 9.0°(6.2°, 12.3°), and 18.5(12.3, 23.6) mm, respectively. Postoperative improvements were noted with values of -11.1°(-8.8°, -14.4°), 1.3°(0.8°, 1.6°), -11.1°(-8.6°, -14.5°), 1.6°(0.5°, 2.2°), and 9.4 (4.8-13.5) mm, respectively. At the final follow-up, these parameters were maintained, with values of -11.0°(-8.8°, -14.3°), 1.2°(0.8°, 1.5°), -11.0° (-8.6°, -14.3°), 1.5°(0.5°, 2.2°), and 9.4(4.8, 13.4) mm, respectively. Statistically significant improvements were observed between preoperative and postoperative measurements ( P<0.05), except for C 1, 2 angle, CSVA, SVA, T 1S, and T 1S-CL ( P>0.05). NDI and SRS-22 scores showed significant improvements postoperatively ( P<0.05), while VAS scores did not show a significant change ( P>0.05). Postoperative complications included transient nerve injury in two patients, one case of right central retinal artery occlusion, and one case of vertebral artery injury. Conclusion:This study confirms the safety and efficacy of single posterior osteotomy for treating rigid CSD of various etiologies. Standard PSO or modified techniques are effective for correcting cervical kyphosis, while hemivertebra resection and concave-side distraction are recommended for congenital scoliosis or kyphoscoliosis.

Objective To analyze the serum differential metabolites and metabolic pathways of patients with refractory gout of spleen deficiency and damp-heat type by metabolomics based on 1 H-NMR.Methods A total of 40 patients with refractory gout acute attack of spleen deficiency and damp-heat type were selected as gout group,and 20 healthy subjects were selected as healthy group.Erythrocyte sedimentation rate and serum C-reactive protein(CRP),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),serum adiponectin and creatinine levels were used as observation indicators.Serum metabolomics analysis was performed using 1 H-NMR method.The obtained data were subjected to principal component analysis(PCA)and orthogonal partial least squares discriminant analysis(OPLS-DA)to determine the corresponding metabolites and analyze the potential metabolic pathways of the differential metabolites.Results Compared with the healthy group,the erythrocyte sedimentation rate,serum CRP,IL-6,TNF-α and other inflammatory indicators and cell chemokine levels in the gout group were significantly increased(P＜0.01);the serum adiponectin level was significantly decreased(P＜0.01),and the serum creatinine level was significantly increased(P＜0.01).There were significant differences in the content of serum metabolites between the healthy group and the gout group.A total of 44 differential metabolites were obtained,involving 12 potential metabolic pathways such as aminoacyl tRNA biosynthesis,valine,leucine and isoleucine biosynthesis,alanine,aspartic acid and glutamic acid metabolism,glycolysis/gluconeogenesis,ketone synthesis and degradation,citric acid cycle(TCA cycle),glutathione metabolism,glyceride metabolism.Conclusion Acute attacks of refractory gout with spleen deficiency and damp-heat type may be associated with disorders of mitochondrial energy metabolism,leading to abnormalities in glucose metabolism,lipid metabolism,and amino acid metabolism.
