Objective To explore the clinical efficacy and safety of one-stage posterior lesion removal and internal spinal fixation in patients with lumbar Brucellosis spondylitis.Methods The clinical data of 24 patients admitted from October 2017 to October 2022 were retrospectively analyzed,2 patients were lost to follow-up at 10 months after surgery,at the final 22 cases were included in the study,including 13 males and 9 females with an average age of(52.00±6.89)years old,were treated with one-stage posterior lesion removal and internal spinal fixation.The operation time,intraoperative bleeding,follow-up time,ery-throcyte sedimentation rate(ESR)and C-reactive protein(CRP)before and after operation were recorded.The pain visual ana-logue scale(VAS),Oswestry disability index(ODI),the Japanese Orthopaedic Association(JOA)score for neurofunction,American Spinal Injury Association(ASIA)spinal cord injury grade and modified MacNab criteria were ussed to evaluate the efficacy.Results All patients were followed up from 12 to 30 months with an average of(17.41±4.45)months.The operation time was 70 to 155 min with an average of(1 16.59±24.32)min;the intraoperative bleeding volume was 120 to 520 ml with an average of(275.00±97.53)ml.CRP and ESR levels decreased more significantly at 1 week and at the final follow-up than pre-operative levels(P＜0.05).VAS,JOA score and ODI at 1 week and at the latest follow-up were more significantly improved than preoperative results(P＜0.05).There was no significant difference between ASIA preoperative and 1 week after operation(P＞0.05),and a significant difference between preoperative and last follow-up(P＜0.05).In the final follow-up,21 patients had ex-cellent efficacy,1 patient had fair,and there was no recurrence during the follow-up.Conclusion One-stage transpedicular le-sion removal and internal spinal fixation,with few incisions and short operation time,helps the recovery of neurological func-tion,and the prognosis meets the clinical requirements,which can effectively control Brucella spondylitis.

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 exploxe the analgesic effect of general anesthesia combined with different concentrations of ropivacaine and transverse abdominis plane block on laparoscopic appendectomy(LA).Methods LA patients from Xiamen University Affiliated Zhongshan Hospital from January 2022 to July 2023 were included.All patients underwent general anesthesia combined ropivacaine plane block of the transverse abdominis muscle.According to the different concentrations of ropivacaine,patients were divided into high concentration group(0.50％,20 mL),medium concentration group(0.375％,20 mL)and low concentration group(0.25％,20 mL).The dosage of fentanyl,postoperative bleeding,time of first press of the analgesic pump,and number of presses among three groups of patients were recorded and compared.The postoperative vital signs(mean arterial pressure and heart rate),pain level(NRS),comfort level(BCS)(1 h,6 h,12 h,and 24 h),and incidence of postoperative adverse reactions were observed and compared.Results This study included a total of 90 LA patients,with 30 cases in each group.The first press of the analgesic pump in the low concentration group was significantly shorter than that in the medium and high concentration groups(P＜0.05),while the number of presses was significantly higher than the other two groups(P＜0.05).The mean arterial pressure and heart rate significantly decreased with the increase of ropivacaine concentration at 1 hour after surgery(P＜0.05);compared with 1 hour after surgery,the average arterial pressure and heart rate of patients in the medium concentration group and low concentration group significantly increased at 6 hours after surgery(P＜0.05),and no significant changes occurred thereafter.The NRS scores of patients in the high concentration group were significantly lower than those in the medium and low concentration groups at all four postoperative time points(P＜0.05);the NRS scores of patients in the medium concentration group were significantly lower than those in the low concentration group at four postoperative time points(P＜0.05).The BCS scores of the low concentration higher than those of the medium concentration group and low concentration group an 1 h,6 h and 24 h.The incidence of adverse reactions in the high concentration group was significantly higher than that in the low concentration group and the medium concentration group(P＜0.05);there was no significant difference in the incidence of adverse reactions between the medium concentration group and the low concentration group(P＞0.05).Conclusion General anesthesia combined with 0.50％ropivacaine abdominal transverse muscle plane block has a significant analgesic effect and high comfort for patients undergoing LA,but the risk of postoperative adverse reactions is high,and the plan needs to be adjusted according to the actual situation.

Objective: To understand the improvement effect of Lycium barbarum polysaccharide (LBP) on the intestinal flora of mother mice during pregnancy and their offspring who experienced chronic stress, and provide new ideas for improving the effect of stress on the intestinal tract. Methods: From July to October 2019, 24 SPF-grade female SD rats were selected and divided into control group, stress group, and stress+LBP group, with 8 rats in each group. A chronic unpredictable mild stimulation model during pregnancy was established (21 days) , and 40 mg/kg LBP solution was administered by gavage on the 8th day of stress. Venous blood from the medial canthus of the female mice was collected on the 1st day before stress and on the 1st, 7th, 14th and 21st days, respectively. Cortisol was measured and corticosterone concentration was calculated. The fresh feces of famale mice after stress and 20-day postnatal offspring mice were collected, and Illumina Miseq sequencing technology, alpha diversity and community composition were used to analyze the diversity and structure of intestinal flora. Results: On the 7th and 14th days of stress, the plasma corticosterone concentration of female mice in the stress group and stress+LBP group was higher than that in the control group (P<0.05) . In the Alpha diversity of female mice, the Ace index of the stress group was lower than that of the control group (P<0.05) . The analysis of intestinal flora structure showed that at the species level, the proportions of Lachnospiraceae and Lactobacillus in the stress+LBP group were higher than those in the stress group and control group. At the order level, the proportion of Clostridiales in the stress+LBP group was higher than that in the stress group and lower than that in the control group, while the proportion of Lactobacillales was higher than that in the stress group and control group. In the Alpha diversity of the offspring group, the Shannon index, Ace index and Chao index of the stress+LBP offspring group were higher than those of the stress offspring group (P<0.05) . The proportion of Lactobacillus in the stress+LBP offspring group was higher than that in the control offspring group and stress offspring group, and the proportions of Lachnospiraceae and Ruminococcaceae in the stress+LBP offspring group were higher than those in the stress offspring group, the proportion of Bacteroidales in the stress+LBP offspring group was lower than that in the stress offspring group, and the proportion of Clostridiales in the stress+LBP offspring group was higher than that in the stress and control offspring groups. Conclusion: The intervention of LBP may improve the changes in the intestinal flora diversity, abundance and flora structure of mother mice and offspring caused by pregnancy stress, thereby maintaining the balance of intestinal flora.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

OBJECTIVE: To analyze the difference in clinical efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) under Quadrant channel system combined with microscope and percutaneous pedicle screw in the treatment of degenerative lumbar spondylolisthesis. METHODS: A total of 114 patients with single-segment degenerative lumbar spondylolisthesis from June 2015 to February 2019, were divided into three groups according to the surgical methods, such as the MIS-TLIF under the microscope surgery group ( microscope group), MIS-TLIF combined with percutaneous pedicle screw technique surgery group(percutaneous group) and posterior lumbar interbody fusion surgery group (open group). In the microscope group, there were 12 males and 26 females, aged from 42 to 83 years with an average of (63.29±9.09) years. In the percutaneous group, there were 16 males and 22 females, aged from 45 to 82 years with an average of (63.37±7.50) years. In the open group, there were 12 males and 26 females, aged from 51 to 82 years with an average of (63.76±8.21) years. The general conditions of operation, such as operation time, intraoperative blood loss, postoperative drainage, length of surgical incision, frequency of intraoperative fluoroscopy and postoperative time of lying in bed were recorded to analyze the differences in surgical related indicators. Visual analogue scale (VAS) of waist and leg pain in preoperative and postoperative period (3 days, 3 months, 6 months and 12 months) were recorded to evaluate pain remission;Oswestry Disability Index(ODI), Japanese Orthopaedic Association (JOA) score were recorded to evaluate the recovery of waist and leg function on preoperative and postoperative 12 months. The lumbar spondylolisthesis rate and intervertebral height at 12 months after operation were recorded to evaluate the reduction of spondylolisthesis. The Siepe intervertebral fusion standard was used to analyze the intervertebral fusion rate at 12 months after operation. RESULTS: ①All 114 patients were followed up more than 1 year, and no complications related to incision infection occurred. In the microscope group, there was 1 case of subcutaneous effusion 8 days after operation. After percutaneous puncture and drainage, waist compression, and then the healing was delayed. In the percutaneous group, 2 cases of paravertebral muscle necrosis occurred on the side of decompression, and the healing was delayed after debridement. In open group, there was 1 case of intraoperative dural tear, which was packed with free adipose tissue during the operation. There was no postoperative cerebrospinal fluid leakage and other related complications.① Compared with microscope group, percutaneous group increased in operation time, intraoperative blood loss, postoperative wound drainage, surgical incision length, intraoperative fluoroscopy times, and postoperative bed rest time. In open group, intraoperative blood loss, postoperative wound drainage, surgical incision length, and postoperative bed rest time increased, but the intraoperative fluoroscopy time decreased. Compared with percutaneous group, the intraoperative blood loss, wound drainage, surgical incision length, and postoperative bed rest time in open group increased, but operative time and the intraoperative fluoroscopy time decreased(P<0.05). ②ODI and JOA scores of the three groups at 12 months after operation were improved compared with those before operation (P<0.05), but there was no significant difference between the three group(P>0.05). ③Compared with microscope group, the VAS of low back pain in percutaneous group increased at 3 days after operation, and VAS of low back pain in open group increased at 3 days, and 12 month after operation. Compared with percutaneous group, the VAS low back pain score of the open group increased at 3 months after operation (P<0.05). ④ The lumbar spondylolisthesis rate of the three groups of patients at 12 months afrer operation was decreased compared with that before operation(P<0.05), and the intervertebral heigh was increased compared with that before operation(P<0.05), however, there was no significant difference among three groups at 12 months afrer operation(P>0.05). ⑤ There was no significant difference between three groups in the lumbar fusion rate at 12 months afrer operation(P>0.05). CONCLUSION The MIS-TLIF assisted by microscope and the MIS-TLIF combined with percutaneous pedicle screw are safe and effective to treat the degenerative lumbar spondylolisthesis with single-segment, and the MIS-TLIF assisted by microscope may be more invasive, cause less blood loss and achieve better clinical efficacy.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

OBJECTIVE: To explore the genetic basis and pregnancy outcome of fetuses with urinary system anomalies. METHODS: Ultrasonographic features, genetic testing and pregnancy outcomes of 337 fetuses with urinary system anomalies identified by prenatal ultrasonograhy were collected for analysis. RESULTS: Ultrasonographic features of the fetuses were mainly characterized by hydronephrosis or hydronephrosis, polycystic kidney disease, and renal dysplasia. Thirty four fetuses (10.1%) were found to harbor a genetic defect, including 14 numerical chromosomal disorders, 10 structural chromosomal aberrations, and 10 pathogenic copy number variations (CNVs). In 31 cases, the parents elected induced labor. For the 303 fetuses with negative findings, 142 were born by spontaneous delivery or Caesarean section, 48 cases underwent induced labor, 1 case had miscarriage, and the remaining 112 cases had unknown or missed pregnancy outcomes. CONCLUSION Hydronephrosis or hydronephrosis, polycystic kidney disease, and renal dysplasia are the most common findings among fetuses with urinary system anomalies. Approximately 10.1% of such fetuses are positive by genetic testing.
