Objective To study whether sulphur fumigation can cause changes to the content of imperatorin in Angelicae Dahuricae Radix (Baizhi).Methods The fresh samples of Angelicae Dahuricae Radix were collected from some cultivation bases. Half of each batch root was fumigated with sulfur according to the conventional method, and another half was cut into slices and dried naturally (i.e. without sulfur fumigation). The content of imperatorin was determined by HPLC on C18 column (4.6 mm×250 mm, 5μm) with a gradient mobile phase of acetonitrile-water solution system at the follow rate of 1.0 mL/min, 35℃ of the column temperature, and the max plot in 210-800 nm of the detective wavelength.ResultsTotally 29 batches of fresh roots ofAngelica dahurica were collected. The average contents of imperatorin were 0.202% in the Angelicae Dahuricae Radix with sulfur fumigation and 0.120% in the Angelicae Dahuricae Radix without sulfur fumigation. Compared with the corresponding samples without sulfur fumigation, the content of imperatorin in every Angelicae Dahuricae Radix with sulfur fumigation decreased by 6.77%-77.56% with an average decrease of 39.86%.Conclusion The content of imperatorin decreased significantly in every batch of Angelicae Dahuricae Radix with sulphur fumigation. It shows that the sulphur fumigation method was not suitable for producing and processing Angelicae Dahuricae Radix from fresh roots ofA. dahurica.

Objective To determine whether rTFPI could inhibit vascular thrombosis and salvage random pattern skin flaps following AIRC in rat models.Methods From April,2013 to June,2015,30 adult male Sprague-Dawley rats were randomized into 3 groups;a control group,an avulsion injury with roll compaction (AIRC) group,and an AIRC plus rTFPI therapy group.An 8.0 cm× 2.5 cm random flap was raised on the dorsum of each rat.The AIRC and AIRC plus rTFPI flaps were then altered with a device designed to simulate avulsion injury with roll compaction.After flap closure primarily,treatment was initiated immediately and continued for 3 days.Phosphate buffered saline was used in the control group and the AIRC group,while the AIRC plus rTFPI group received the recombinant Tissue Factor Pathway Inhibitor.Laser Doppler flowmetry and infra-red thermalgraphy were used on postoperative day three to assess nicrocirculatory blood flow and viability of the avulsed flaps.At postoperative day seven,final flap survival was determined.Using SPSS19.0 statistical analysis.Results The flap survival in AIRC group was only (32.7 ± 5.2)％ versus (62.5 ± 6.5)％ in control group,but the flap survival significantly increased (51.6 ± 8.2)％ after topical injecting rTFPI in experimental group.Statistically significant differences exist (P ＜ 0.05) between every two groups.The detection results of Laser-Doppler flowmetry and infra-red thermography showed that perfusion arrived the centre of the flaps in experimental group,while perfusion only arrived the proximal part of the flaps in the AIRC control group.Conclusion rTFPI therapy is effective in reducing ischemic necrosis of random pattern flaps following avulsion injury in the rat model.It suggests that rTFPI therapy may play an important role in clinical salvage of the failing avulsion injuries with roll compaction.

OBJECTIVE: To carry out genetic and metabolite analysis for an infant with cerebral creatine deficiency syndrome type 2 (CCDS2). METHODS: Clinical data of the child was collected. Whole-exome sequencing was carried out to identify potential variants by next generation sequencing. Candidate variants were confirmed by Sanger sequencing. Metabolites were determined by tandem mass spectrometry and magnetic resonance spectroscopy. Treatment was carried out following the diagnosis and genetic counseling for the affected family. RESULTS: Two novel heterozygous variants (c.289delC and c.392-1G>C) of the GAMT gene were identified in the proband, which were respectively inherited from her father and mother. In silico analysis suggested both variants to be pathogenic. Creatine (Cr) level of the child was very low, and cerebral guanidinoacetate (GAA) level was slightly increased. But both had recovered to normal in two weeks, and cerebral Cr level was significantly improved after two months. Intellectual and motor development of the child were significantly improved. CONCLUSION The child was diagnosed with CCDS type 2, for which pathogenic variants of the GAMT gene may be accountable. Treatment has attained a satisfactory effect for the patient.

Spinal cord injury is a common clinical disease secondary to spinal cord fractures that causes patients with motor and sensory dysfunction or even paralysis. In recent years, exosomes have participated in the occurrence and development of various diseases as nanometer-sized cell particles, and have received extensive attention. Exosomes derived from spinal cord tissue cells during spinal cord injury affect the injury process and tissue repair. In addition, exosomes as a new treatment for spinal cord injury have been widely studied. The authors document the mechanisms of various exosomes from spinal cord tissue and the repair effects of various cell-derived exosomes in spinal cord injury, in order to deepen the understanding of the role of exosomes in spinal cord injury and provide new ideas for studying the course and treatment of spinal cord injury.

Objective:To summarize and analyze the clinical and genetic characteristics of Chinese patients with adrenomyeloneuropathy (AMN).Methods:Clinical data were collected and analyzed retrospectively on AMN patients who were diagnosed by genetic testing in Shanghai Sixth People′s Hospital, Shanghai Jiao Tong University School of Medicine from May 2008 to August 2022. Clinical characteristics of AMN patients with different types of gene mutations were compared. Loe score was used to evaluate the severity of white matter demyelinating, and the serum levels of very long-chain fatty acids (VLCFA) in patients with or without white matter demyelinating were compared. The motor function of the AMN patients was assessed using the Expanded Disability Status Scale (EDSS), and the association between EDSS scores and the course of disease was analyzed.Results:A total of 23 male patients with onset age of (29.52±9.91) years were included in this study. The first symptom of all patients was abnormal lower extremities, of which 17 patients showed stiffness and weakness in their lower limbs (73.9%, 17/23), and 6 patients showed numbness and pain in both lower limbs (26.1%, 6/23). The occurrence of symptoms was not related to the type of gene mutation. White matter demyelination occurred in 33.3% (7/21) of patients over a disease duration of (7.67±4.46) years. There was no statistically significant difference in serum VLCFA level between the white-matter demyelination group and the non-demyelination group. The EDSS score was positively correlated with the disease duration ( r=0.57, P=0.006). Sixteen ABCD1 gene mutations were found in this study, among which c.5_19delinsTCTCCAGG (p.P2Lfs *12) was reported for the first time. Four probands belonging to different families carried the c.1415_1416del (p.Q472Rfs *83) variant. Conclusions:Lower limb movement disorders and sensory dysfunction are the prominent clinical manifestations in AMN patients, with deterioration of motor function associated with the course of disease. AMN may be converted to cerebral type and VLCFA concentration is not associated with the phenotypic changes. The c.1415_1416del (p.Q472Rfs *83) mutation is a hot spot mutation of the disease.

Objective:To analyze the clinical characteristics of acute pancreatitis.Methods:The retrospective case-control study was conducted. The clinical data of 558 patients with acute pancreatitis who were admitted to The First Affiliated Hospital of Xi′an Jiaotong University from June 2015 to June 2023 were collected. There were 352 males and 206 females, aged (46±15)years. Observation indicators: (1) general situations of acute pancreatitis patients; (2) etiology of acute pancreatitis patients; (3) severity of acute pancreatitis patients; (4) chronic diseases in acute pan-creatitis patients; (5) complications in acute pancreatitis patients; (6) subgroup analysis of patients with recurrent acute pancreatitis. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Bonferroni correction was used for pairwise comparison. Results:(1) General situations of acute pancreatitis patients. There were significant differences in gender, age, total duration of hospital stay, smoking, and alcohol consumption between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (2) Etiology of acute pancreatitis patients. There were significant differences in gallstones and hyperlipidemia between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (3) Severity of acute pancreatitis patients. Of the 443 patients with first episode of acute pancreatitis and 115 patients with recurrent acute pancreatitis, cases with mild acute pancreatitis, cases with moderate-severe acute pancreatitis, cases with severe acute pan-creatitis were 320 and 83, 24 and 9, 99 and 23, showing no significant difference between them ( P>0.05). (4) Chronic diseases in acute pancreatitis patients. There were significant differences in com-plication as hyperlipidemia, fatty liver and diabetes between the first episode of acute pancreatitis patients and the recurrent acute pancreatitis patients ( P<0.05). (5) Complications in acute pancrea-titis patients. There was no significant difference in terms of acute necrotic collection, acute peripan-creatic fluid accumulation, walled-off necrosis, pancreatic pseudocyst, infectious pancreatic necrosis, systemic inflammatory response syndrome, respiratory system complications, circulatory system complications, renal complications, sepsis, abdominal compartment syndrome, or pancreatic ence-phalopathy between the first episode of acute pancreatitis patients and the recurrent acute pancrea-titis patients ( P>0.05). (6) Subgroup analysis of patients with recurrent acute pancreatitis. ① Combination with chronic diseases. Of the 115 patients with recurrent acute pancreatitis, cases with mild acute pancreatitis, cases with moderate-severe acute pancreatitis, cases with severe acute pancreatitis were 83, 9, 23, and there were 25, 8, 11 cases of them with hyperlipidemia, respectively, showing a significant difference among them ( P<0.05). ② Complications. Of the 115 patients with recurrent acute pancreatitis, there were 44 cases with hyperlipidemia and 71 cases without hyper-lipidemia, and there were significant differences in acute peripancreatic fluid accumulation and renal complications between them ( P<0.05). Conclusions:Recurrent acute pancreatitis is more common in males. Compared with first episode of acute pancreatitis, cases with recurrent acute pancreatitis usually have younger age, shorter total duration of hospital stay, higher proportion of smoking and drinking. The etiology of recurrent acute pancreatitis is composed of lower levels of biliary diseases and higher levels of hyperlipidemia. Patients with recurrent acute pancreatitis have higher proportion of comorbidities as hyperlipidemia, fatty liver and diabetes. There was no signifi-cant difference in the incidence of complications between first episode of acute pancreatitis and recurrent acute pancreatitis. Compared with recurrent acute pancreatitis patients without concomi-tant hyperlipidemia, recurrent acute pancreatitis patients with concomitant hyperlipidemia are more prone to acute peripancreatic fluid accumulation and renal complications.

Objective:To explore the effects of psychological intervention based on resourcefulness theory on the management of aggression and violence attitude and resilience of emergency nurses.Methods:Totally 60 nurses who worked in the Emergency Department of the 904 Hospital, the People's Liberation Army Joint Logistic Support Force from January 2020 to December 2021 were selected by convenience sampling. According to the enrollment time, the nurses enrolled from January to December 2020 were included as the control group, and the nurses enrolled from January to December 2021 were included as the intervention group, with 30 nurses in each group. Nurses in the control group received routine psychological training, while nurses in the intervention group was trained with a psychological intervention program based on resourcefulness theory based on the training provided to the control group. The nurses were surveyed and the intervention effect was evaluated by Resourcefulness Scale, Management of Aggression and Violence Attitude Scale (MAVAS), Medical Professionals Resilience Scale (MeRS), and Nurses' Work Alienation Questionnaire (NWAQ) .Results:After intervention, the scores of Resourcefulness Scale, MAVAS and MeRS of nurses in the intervention group were higher than those in the control group, and the scores of NWAQ were lower than those in the control group, with statistical significance between the two groups ( P<0.05) . Conclusions:Psychological intervention based on resourcefulness theory can enhance the resourcefulness of emergency nurses, improve their management of aggression and violence attitudes, strengthen their deep understanding of work violence and their level of resilience, reduce their sense of alienation at work, and alleviate negative psychological emotions. Therefore, it is worth promoting in clinical practice.
