Fuxiong has a long history of cultivation. Since its first record in the Beneficial Formulas from the Taiping Imperial Pharmacy of the Song Dynasty, Fuxiong had always been used by ancient physicians and became a preponderant variety for some reasons during the periods of the Ming Dynasty, Qing Dynasty, and Republic of China. However, as for modern use, only Chuanxiong Rhizoma is valued, and the medicinal value of Fuxiong is gradually being overlooked. This article systematically researches the nomenclature, producing area, origin, and efficacy of Fuxiong, proving that the planting technology of Fuxiong matured in the Song Dynasty at the latest, slightly later than the emergence of Chuanxiong Rhizoma in the Sui and Tang Dynasties. Over the years, the producing area of Fuxiong has not undergone significant changes, and it is mainly cultivated within Jiangxi province. According to the analysis of the origin of Xiongqiong, combined with modern genetic research, it can be basically clarified that the early source of Xiongqiong may not be single. With the popularization of cultivation, Chuanxiong Rhizoma became a Dao-di herb earliest, gradually replacing Xiongqiong and being recognized clinically. After cultivation, the polyploidy of Chuanxiong Rhizoma varieties formed stable inheritance, forming the later Fuxiong. Medical experts have gradually deepened their understanding of the efficacy of Fuxiong. Initially, they believed that it was a substitute for Chuanxiong Rhizoma and had weaker efficacy than Chuanxiong Rhizoma. Medical experts in Jin and Yuan Dynasties such as Zhu Danxi and Dai Sigong believed that Fuxiong was good at relieving stagnation. Books and records of materia medica in the Ming and Qing Dynasties explicitly proposed the great ability of Fuxiong to relieve stagnation. Fuxiong should be distinguished from Chuanxiong Rhizoma when applied, and the application differences should be clearly reflected in medical records. Based on the comprehensive research in this article, it can be concluded that although most of ancient physicians have attached great importance to genuineness of Chuanxiong Rhizoma, Fuxiong, as a dominant variety of traditional application, has a clear historical context and significant efficacy characteristics, worthy of further in-depth study.

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.

RBM46 is a germ cell-specific RNA-binding protein required for gametogenesis, but the targets and molecular functions of RBM46 remain unknown. Here, we demonstrate that RBM46 binds at specific motifs in the 3'UTRs of mRNAs encoding multiple meiotic cohesin subunits and show that RBM46 is required for normal synaptonemal complex formation during meiosis initiation. Using a recently reported, high-resolution technique known as LACE-seq and working with low-input cells, we profiled the targets of RBM46 at single-nucleotide resolution in leptotene and zygotene stage gametes. We found that RBM46 preferentially binds target mRNAs containing GCCUAU/GUUCGA motifs in their 3'UTRs regions. In Rbm46 knockout mice, the RBM46-target cohesin subunits displayed unaltered mRNA levels but had reduced translation, resulting in the failed assembly of axial elements, synapsis disruption, and meiotic arrest. Our study thus provides mechanistic insights into the molecular functions of RBM46 in gametogenesis and illustrates the power of LACE-seq for investigations of RNA-binding protein functions when working with low-abundance input materials.

【Objective】 To explore the predictive value of preoperative liver function for massive blood transfusion (MBT) in patients undergoing ascending aorta surgery. 【Methods】 Data from 238 patients undergoing ascending aorta surgery in the Department of Cardiovascular Surgery at The Affiliated Lihuili Hospital of Ningbo University were collected. Preoperative liver function tests were performed for all patients. Based on the perioperative transfusion volumes of red blood cell suspension, patients were divided into the MBT group, non-MBT group, and no blood transfusion (NBT) group. Clinical data during the perioperative period were compared among different groups. Receiver operating characteristic curve (ROC curve) analysis was used to assess the predictive value of liver function indicators for MBT and determine cut-off values. 【Results】 Compared with the non-MBT group and NBT group, the MBT group showed statistically significant differences in preoperative levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), direct bilirubin (DBIL), and serum albumin (SA) (P<0.05). ROC curve analysis revealed that AST had the largest area under the curve (AUC) for predicting MBT, with a value of 0.723. ALT had the highest specificity for predicting MBT at 86.7%, and SA had the highest sensitivity at 89.7%. When AST >28.50 U/L, ALT >40.00 U/L, SA ≤34.55 g/L, and DBIL >4.25 μmol/L, there was a significant increase in the transfusion volume of various blood components and the incidence of MBT. 【Conclusion】 Preoperative liver function indicators (AST, ALT, SA, DBIL) have a moderate predictive value for MBT in patients undergoing ascending aorta surgery.

Objective:This study aimed to explore the clinical application value of the indication selection criteria for bi-pedicled deep inferior epigastric arterial perforator flap(DIEP) versus pedicled transverse rectus abdominis myocutaneous flap(TRAM) combined with DIEP for breast reconstruction.Methods:The clinical data of patients who underwent delayed bi-pedicled abdominal flap breast reconstruction after breast cancer surgery in the Department of Oncoplastic and Reconstructive Breast Surgery and Department of Mammoplasty, Plastic Surgery Hospital, Chinese Academy of Medical Sciences from January 2008 to April 2022 were retrospectively analyzed. According to the indications for each procedure, corresponding blood supply source was selected. Subsequently, patients were divided into two groups: bi-pedicled DIEP group and pedicled TRAM+ DIEP combined flap group according to the type of blood supply source. The indication selection criteria for pedicled TRAM+ DIEP combined flap was as follows: lack of two groups of recipient vessels; no dominant perforator in the abdominal donor site; previous abdominal liposuction or abdominal surgery with large dissection range and severe scar; patients were unable to tolerate prolonged surgery or had high risk factors for microsurgery. A comparison of breast reconstruction surgery characteristics was conducted between the two groups. Independent-samples t-test, rank sum test, Chi-square test and Fisher’s exact probability method were used to analyze various data including age, body mass index (BMI), time interval between breast cancer surgery and breast reconstruction surgery, history of radiotherapy, history of chemotherapy, history of smoking, history of lower abdominal surgery, history of hypertension, original surgical incision type, length and width of flap, hospitalization length, preoperative and postoperative conditions, as well as postoperative complications. Statistical significance was defined at P<0.05. Results:A total of 54 patients who underwent unilateral breast reconstruction were included in this study with a mean age of 42.2 years (range, 30-59 years). The pedicled TRAM+ DIEP combined flap group consisted of 21 patients with a mean age of 42.7 years (range, 33-56 years) while the bi-pedicled DIEP group comprised 33 patients with a mean age of 41.8 years (30-59 years). Out of the 54 patients, a total of 38 were eventually followed up, comprising 14 in the pedicled TRAM+ DIEP combined flap group and 24 in the bi-pedicled DIEP group. The average follow-up duration for the pedicled TRAM+ DIEP combined flap group was 42 months (range, 6-69 months). Abdominal bulge occurred in one patient, while another patient experienced abdominal hernia. The average follow-up duration for the bi-pedicled DIEP group was 47 months (6-179 months), with no reported cases of abdominal bulge or abdominal hernia. There were no statistically significant differences observed between the two groups regarding age, BMI, time interval between breast cancer surgery and breast reconstruction surgery, history of radiotherapy or chemotherapy, history of smoking, history of lower abdominal surgery, history of hypertension, original surgical incision type, length and width of flap, hospitalization length or time to ambulation (all P>0.05). However, there was a statistically significant difference noted in duration of surgery between the pedicled TRAM+ DIEP combined flap group and bi-pedicled DIEP group [6.0(5.5-6.5) hours vs. 8.5(8.0-8.8) hours] ( P<0.01). Comparison analysis revealed no statistically significant differences in terms of partial flap necrosis (0/21 vs. 1/33), abdominal incision dehiscence (2/21 vs. 2/33), abdominal bulge (1/14 vs. 0 /24) or abdominal hernia (1/1 vs. 0/24) between the two groups ( P>0.05). Conclusion:For patients who needed bilateral vascular pedicled lower abdominal wall for breast reconstruction, utilizing a pedicled TRAM+ DIEP combined flap did not increase surgical complication risks. The proposed indication selection criteria for using a pedicled TRAM + DIEP combined flap outlined in this study could serve as guidance when choosing methods for bi-pedicled abdominal flap breast reconstruction.

Objective:To preliminarily evaluate the outcome of fat grafting breast augmentation using filtration-adsorption technique.Methods:Patients undergoing autologous fat grafting (AFG) breast augmentation between July of 2020 and March of 2021 were retrospectively reviewed at Breast Plastic and Reconstructive Surgery Center, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College. Patients with complete data who followed up for at least 3 months were included. The lipoaspirates were processed with filtration-adsorption technique and AFG breast augmentation were performed (filtration-adsorption group), and then sedimentation method which was commonly used clinically was set as the control group (sedimentation group). During the follow-up, breast palpation and ultrasound inspection were performed, and the breast volumetric change between preoperative and postoperative was quantitatively compared by three-dimensional scanning technique. Demographic and surgical details were statistically analyzed. Postoperative breast volume retention rates and complication rates were calculated and compared. Normally distributed continuous variables were described in the form Mean±SD, and t-test was used for analysis. Non-normal distributed continuous variables were described in the form of M ( Q1, Q3) and analyzed by Mann-Whitney U test. The classified data were analyzed by Fisher exact probability test. Results:A total of 20 female patients (40 breasts) were included, including 10 patients (20 breasts) aged (31.4±2.5) years in sedimentation group and 10 patients (20 breasts) aged (28.5±4.4) years in the filtration-adsorption group. The fat injection volume in the filtration-adsorption group was 151.1 (125.0, 175.0) ml, and 165.0 (151.3, 196.3) ml in sedimentation group, respectively, with no statistical significance ( P>0.05). The breast volume retention rate in filtration-adsorption group was (62.93±14.06)%, which was significantly higher than that in sedimentation group (24.97±11.02)% ( P<0.01). During postoperative breast ultrasound examination, 2 breasts in sedimentation group had palpable nodules (< 6 mm), 1 breast had ultrasonically detectable but clinically inaccessible nodules (< 4 mm), while only 1 breast in the filtration-adsorption group had an oil cyst (4 mm×2 mm). The complication rate in the filtration-adsorption group was lower than that in sedimentation group[5.0%(1/20) vs. 15.0%(3/20), P>0.05]. Conclusion:The filtration-adsorption technique is an ideal method for fat grafting, which would multiply the volume retention rate in large-volume AFG breast augmentation and reduce the rate of complications.

Objective To investigate the distribution of mosquito species and their associated viruses, and identify Culex pipiens subspecies in Hami City, Xinjiang Uygur Autonomous Region. Methods Mosquitoes were captured using mosquito trapping lamps method in Yizhou District, Yiwu County, and Balikun County of Hami City in mi-July, 2019 and 2020. The species and subspecies of all captured mosquitoes were characterized. In addition, the flavivirus, alphavirus, bunyavirus, Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis virus and West Nile virus were detected using reverse-transcription PCR assay in captured mosquitoes. Results A total of 1 496 mosquitoes were captured from Yizhou District, Yiwu County, and Balikun County of Hami City, belonging to 3 genus and 3 species. Cx. pipiens was the dominant mosquito species (986 mosquitoes, 65.91%), followed by Aedes caspius (457 mosquitoes, 30.55%), while Culiseta alaskaensis had the lowest number (53 mosquitoes, 3.54%). All captured Cx. pipiens mosquitoes were identified as Cx. pipiens pipiens based on the terminalia of male mosquitoes. RT-PCR assay tested negative for flavivirus, alphavirus, bunyavirus, Japanese encephalitis virus, Liaoning virus, Tahyna virus, tick-borne encephalitis or West Nile virus in captured Cx. pipiens mosquitoes. Conclusions There were 3 species of mosquitoes in Hami City from 2019 to 2020, including Cx. pipiens, Ae. Caspius and C. alaskaensis, with Cx. pipiens as the dominant mosquito species, and all captured Cx. pipiens mosquitoes were Cx. pipiens pipiens; however, no arboviruses were detected.

Objective: To investigate the clinicopathological features of very well-differentiated adenocarcinoma (VWDA) of the stomach. Methods: The clinicopathological data of 12 cases of VWDA of the stomach were collected retrospectively at the People's Liberation Army Joint Logistics Support Force 989 Hospital (formerly 152 Hospital), Pingdingshan, China, from January 2013 to May 2021. The histological characteristics and immunophenotypes were observed and analyzed with review of current literature. Results: There were 8 males and 4 females with a median age of 63 years (range 47 to 80 years). The tumor involved in the upper part of the stomach in 6 cases, the middle part in 2 cases, and the lower part in 4 cases. The median diameter of the tumors was 17 mm (range 5-65 mm). The tumor cells were similar to absorbent cells, Paneth cells, foveolar epithelial cells, and goblet cells. The cells were arranged in a single layer, and the nuclei were slightly enlarged and located at the base. The nuclei were fusiform to slightly irregular, with loss of nuclear polarity. Early tubular VWDA was found in 9 cases, and the tumor glands were similar to intestinal metaplasia. In two cases the tumors infiltrated into the submucosa. The lesions in the mucosa and submucosa showed the glands with cystic expansion, bending, branching, spiky and abortive growth pattern. One case of early papillary tubular VWDA was confined to the mucosal layer and composed of foveolar-type epithelial cells. There were two cases of advanced papillary tubular VWDA, which consisted of foveolar-type epithelial, pyloric glands, or mucinous neck cells and were associated with intra-lymphatic cancer embolus and lymph node metastases. Background mucosal atrophy and intestinal metaplasia were observed in all cases. Immunohistochemical staining showed intestinal type VWDA in 1 case, mixed gastrointestinal type VWDA in 9 cases, and gastric type VWDA in 2 cases. The Ki-67 proliferation index of 8 cases limited to the mucosa was 40%-70%, 2 cases of infiltration into the submucosa and 2 cases of advanced carcinoma was 10%-25%. All the tumors showed a wild type of p53 protein expression pattern and negative HER2. Adenocarcinoma or high-grade dysplasia was diagnosed on preoperative biopsy in 5 cases, and chronic atrophic gastritis with intestinal metaplasia in 7 cases. The median follow-up time was 28 months (range 12-72 months). No recurrence was found in the 10 patients with early cancer. Of the two patients with advanced carcinoma, one patient had lung metastases and the other died. Conclusions: Gastric VWDA is a rare low-grade malignancy with structural features of highly differentiated adenocarcinoma and extremely low cytological atypia. The diagnostic value of structural abnormality is significantly greater than cytological atypia. The invasive growth of irregular glands in the deep mucosa and submucosa is reliable evidence for diagnosis. The diagnosis of intramucosal VWDA is challenging and very difficult in some biopsy specimens.
