ObjectiveThis study aims to explore the effect of ultrasound-guided superficial parasternal intercostal plane block on the quality of recovery and postoperative analgesia in patients undergoing sternotomy cardiac surgery. MethodsA total of 64 patients undergoing sternotomy cardiac surgery were selected for this study. They were randomly divided into two groups： one group received a superficial parasternal intercostal plane block with ropivacaine （the ropivacaine group）， while the other was given normal saline （the normal saline group）. The primary outcome was the Quality of Recovery-15 （QoR-15） score on postoperative day 1 in both groups， accompanied by a comparative analysis of the pain score and opioid usage. ResultsCompared with the normal saline group， the ropivacaine group exhibited a significantly higher QoR-15 score on postoperative day 1［（89.60±13.24） vs （81.18±12.78）， P=0.012］. The numerical rating scale at rest was significantly lower［（3.03±0.72） vs （4.26±0.93）， P<0.001］， and the numerical rating scale during coughing was also significantly reduced ［（4.40±0.89） vs （5.44±1.05）， P<0.001］. Concurrently， the cumulative morphine equivalent consumption during the initial 24 h postoperatively was significantly lower in patients who were administered the ropivacaine ［14.15 （4.95～30.00） mg vs 40.50 （19.25～68.18） mg， P=0.002］， and there was also a notable decrease in the rescue analgesia ［0.00 （0.00～0.00） mg vs 0.00 （0.00～100.00） mg， P=0.007］. ConclusionUltrasound-guided superficial parasternal intercostal plane block can significantly enhance the overall quality of recovery in patients undergoing sternotomy cardiac surgery on postoperative day 1. The technique contributes to improved postoperative analgesic effects and a reduction in opioid usage， thereby facilitating early postoperative recovery.

This case identifies novel mutation sites in the NNT gene, providing a basis for the early diagnosis and treatment of FGD4 patients.

Objective:To assess the risk of venous thromboembolism (VTE) and anticoagulation-related bleeding of acute critical emergency patients staying in the emergency department at least 72 h, so as to improve the ability of emergency physicians to identify risk factors of VTE and their awareness of safety prevention in these patients.Methods:Multicenter emergency internal medicine patients meeting the inclusion criteria at the same time were collected. Padua and Caprini scores were used to evaluate the risk of VTE and the HAS-BLED score was used to assess the risk of anticoagulation-related bleeding.Results:A total of 930 emergency patients from 7 medical centers were enrolled in our study from January 15, 2021 to March 15, 2021. The proportion of high-risk population with VTE was 50.22% with Padua score and 78.49% with Caprini score, respectively. The proportion of high-risk bleeding (HAS-BLED score) was 40.43%.Conclusions:More than half of the acute critical ill patients who stay in emergency department for more than 72 h are at high risk of VTE. This group of patients have a relatively low risk of anticoagulation-related bleeding.

Objective:To explore the effect of behavior change wheel strategy based on information asymmetry in the postoperative rehabilitation of patients with thoracolumbar fracture.Methods:From June 2020 to May 2021, 164 patients with thoracolumbar fracture in Spine Surgery who were admitted to the First Affiliated Hospital of Xinxiang Medical University were selected by convenience sampling as the research object. The patients were divided into observation group and control group according to random number table, 82 cases each. The control group adopted routine postoperative nursing management, while the observation group implemented the behavioral change wheel strategy based on nurse patient information asymmetry on the basis of the control group. After three months of intervention, the differences of kinesiophobia and recovery of lumbar and back function between the two groups were compared.Results:After intervention, the scores of kinesiophobia and recovery of lumbar and back function in the observation group at the end of the first, second and third months were lower than those in the control group, with statistically significant differences ( P<0.05) . Conclusions:The behavior change wheel strategy based on nurse patient information asymmetry can effectively alleviate postoperative kinesiophobia of patients undergoing thoracolumbar fracture surgery, and improve the recovery of lumbar and back functions after surgery.

Objective: To investigate vitamin D levels among primary and middle school students in Xicheng District, Beijing Municipality, and to examine the association of vitamin D levels with hemoglobin (Hb) and serum ferritin (SF) levels, so as to provide insights into the prevention of anemia among primary and middle school students. Methods: The first, third and fifth grade primary school students and the first grade junior high school students were sampled from Xicheng District in 2019, using the multistage stratified cluster sampling method, and students' gender, age, height, weight and Hb levels were collected. The 25-hydroxyvitamin D [25-( OH )D] was measured using electrochemiluminescence assay, and SF was detected using immunoturbidimetry. The vitamin D deficiency was determined according to the American College of Endocrinology guidelines. The associations of 25-( OH) D levels with Hb and SF levels were examined using Pearson correlation analysis and Spearman rank correlation analysis. Results: Totally 403 primary and junior high school students were investigated, including 196 boys ( 48.64% ) and 207 girls ( 51.36% ). There were 179, 114 and 110 students at ages of 6 to 8 years ( 44.41% ), 9 to 11 years ( 28.29% ) and 12 to 13 years ( 27.30% ), respectively. The mean 25-( OH )D level was ( 14.80±5.96 ) ng/mL among the study students, and there were 90 students ( 22.33% ) with severe vitamin D deficiency, 243 students ( 60.30% ) with vitamin D deficiency, 63 students ( 15.63% ) with vitamin D inadequacy and 7 students ( 1.74% ) with vitamin D sufficiency. The mean Hb level was ( 136.28±8.33 ) g/L and the median SF level (interquartile range) was 56.80 (14.36) ng/mL among the study students, respectively. The 25-( OH )D level positively correlated with Hb ( r=0.364, P<0.001 ) and SF levels ( rs=0.374, P<0.001 ), and after adjustment for age and body mass index, the 25-( OH )D still correlated positively with Hb ( r=0.157, P=0.048 ) and SF levels ( rs=0.174, P=0.022 ) . Conclusions Vitamin D deficiency is prevalent among primary and middle school students in Xicheng District, and the 25-(OH)-D levels correlate positively with Hb and SF levels. 25-( OH )-D deficiency may contribute to the development of anemia.

Objective : To investigate the status of occupational stress and analyze its influencing factors among frontline employees working in a chemical fiber manufacturing enterprise, so as to provide insights into the development of occupational stress interventions. Methods : The frontline employees working in a chemical fiber manufacturing enterprise were selected as the study subjects using a cluster sampling method in October 2018. The status of occupational stress was investigated using the Chinese version of the effort-reward imbalance ( ERI ) questionnaire. The influencing factors for occupational stress were identified using a multivariable logistic regression model. Results : A total of 1 780 questionnaires were sent out, and 1 115 valid ones ( 62.64% ) were recovered. Among the 1 115 respondents, there were 427 men ( 38.30% ) and 688 women ( 61.70% ), and 71.22% were at ages of 21 to 39 years. There were 561 respondents with < 1 year of service ( 50.31% ), and the longest length of service was 11 years. In addition, there were 1 069 respondents ( 95.87% ) exposed to high noise, and 346 respondents ( 31.03% ) were diagnosed at a high occupational-stress state and 769 ( 68.97% ) at a low state. Multivariable logistic regression analysis identified 5 years or longer of service ( OR=1.540, 95%CI: 1.057-2.245 ) and exposure to high noise ( OR=1.917, 95%CI: 1.004-3.659 ) as risk factors for occupational stress among frontline employees in the chemical fiber manufacturing enterprise. Conclusions There are 31.03% of frontline employees at a high occupational-stress state in the chemical fiber manufacturing enterprise, and a high occupational-stress state is associated with exposure to high noise and 5 years or longer of service.

Objective:To explore the clinical characteristics and etiology of children with alimentary tract hemorrhage so as to optimize the diagnosis and treatment.Methods:The clinical data of 2 054 children with alimentary tract hemorrhage in Kunming Children′s Hospital from January 2014 to December 2018 were retrospectively analyzed.Results:Among 2 054 children with alimentary tract hemorrhage, males was in 1 274 cases, females was in 780 cases, and the ratio of males to females was 1.6∶1; <3.0 years old was in 647 cases (31.5%), 3.0 to 5.9 years old was in 488 cases (23.8%), 6.0 to 8.9 years old was in 413 cases (20.1%), 9.0 to 11.9 years old was in 281 cases (13.7%), and ≥12 years old was in 225 cases (11.0%); upper alimentary tract hemorrhage was in 991 cases, lower alimentary tract hemorrhage was in 1063 cases. The top three causes of children with upper alimentary tract hemorrhage were acute or chronic gastritis/ gastric ulcer, anaphylactoid purpura and systemic serious infection; the top three causes of children with lower alimentary tract hemorrhage were intestinal polyps, anaphylactoid purpura and food protein allergic colitis. A rare causes of alimentary tract hemorrhage had Peutz-Jeghers syndrome, cavernous transformation of portal vein, Bartter syndrome, systemic lupus erythematosus, Budd-Chiari syndrome, annular pancreas, Reye syndrome, Klippel-Trenaunay syndrome, Evans syndrome and perianal angiectasia and so on.Conclusions:Alimentary tract hemorrhage is a common disease in pediatrics. With the increase of age, the proportion of children with alimentary tract hemorrhage decreased. The main causes of upper and lower alimentary tract hemorrhage are different in different age stages. In addition to paying attention to common causes, the rare causes of alimentary tract hemorrhage should be vigilant and recognized.

OBJECTIVE: To explore the genetic basis for a child with 46,XY disorders of sex development (DSD) and explore its genotype-phenotype correlation. METHODS: The child was subjected to whole exome sequencing (WES), and exons 1 to 7 of NR5A1 were subjected to multiplex ligation-dependent probe amplification (MLPA) analysis. RESULTS: The patient presented with rudimentary vulva of a female with Tanner stage 1. B-mode ultrasonography has detected ovary and uterus. The child was found to have a chromosome karyotype of 46,XY. WES revealed that the patient has harbored heterozygous deletion of exon 5 of the NR5A1 gene, which was a novel pathogenic variant inherited from the mother. No abnormality was found in the father. CONCLUSION The main symptoms of 46,XY DSD children are insufficient external genitalia masculinization, for which variants of the NR5A1 gene are an important cause. WES has improved the detection rate of genetic variants and provided a solid basis for genetic counseling of the affected families.

Objective:To investigate the neuroprotective effect of long-term prophylactic use of buphthalein on mice with permanent distal middle cerebral artery occlusion and its relationship with the nuclear factor erysid 2 related factor 2 (Nrf2) pathway.Methods:Nrf2 + /+ wild-type and Nrf2 -/- knockout mice were randomly divided into control group (equal volume vegetable oil), low-dose butylphthalide group (20 mg/kg) and high-dose butylphthalide group (60 mg/kg), with 6 mice in each group. The drug was administered once a day by gavage for 1 month, and then a permanent middle cerebral artery occlusion model was induced by electrocoagulation. After the model was made, the drug was continued and the mice were sacrificed on the 10 th day. The modified Longa grading scale and the rotating rod test were used to evaluate neurological deficits on the 3 rd and 10 th day after the model was made. After the mice were sacrificed, the cerebral infarct volume was measured by triphenyltetrazolium chloride staining. The brain water content was measured by dry and wet weight method. The expression of Nrf2 pathway related factors, including Nrf2, heme oxygenase 1 (HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1) were measured by quantitative real-time PCR and Western blotting. Results:On the 10 th day after modeling, compared with the Nrf2 -/- control group, the neurological deficit was significantly milder, the volume of cerebral infarction and brain water content were significantly smaller, and the mRNA and protein levels of Nrf2, HO-1 and NQO1 were significantly higher in the Nrf2 + /+ control group, and the differences were statistically significant ( P<0.05). For Nrf2 + /+ mice, compared with the control group, the cerebral infarct volume was significantly reduced ( P<0.05), the brain water content was significantly reduced ( P<0.05), and the neurological function recovery was significantly better ( P<0.05), and the levels of Nrf2, HO-1, and NQO1 mRNA and protein were significantly higher in the high-dose butylphthalide group (all P<0.05). For Nrf2 -/- mice, there were no significant differences in neurological function, cerebral infarction group volume, brain water content, Nrf2, HO-1, NQO1 mRNA and protein levels among the groups. Conclusion:Long-term butylphthalide pretreatment can significantly improve the neurological function, reduce cerebral infarction volume, reduce brain water content, and increase Nrf2, HO-1, NQO1 mRNA and protein expression levels in mice with permanent distal middle cerebral artery occlusion, suggesting butylphthalide may play a neuroprotective effect by up-regulating the expression of Nrf2 gene and its downstream antioxidant stress factors HO-1 and NQO1.

Objective:To investigate the predictive value of tumor regression rate after induction chemotherapy for survival of patients with locally advanced nasopharyngeal carcinoma.Methods:A total of 161 patients with stage Ⅲ-ⅣA nasopharyngeal carcinoma newly diagnosed at the Daping Hospital of Army Medical University from January 2009 to December 2012 were selected as the research subjects. The relationships between tumor size changes before and after induction chemotherapy and survival time were analyzed. Kaplan-Meier method was used to draw the survival curve accompanied with log-rank test. Cox regression analysis was used to analyze the risk factors affecting the prognosis of patients with nasopharyngeal carcinoma.Results:There were statistically significant differences in the tumor regression rate of primary lesions between N 1and N 2-3( Z=2.177, P=0.029), T 1-2and T 3-4( Z=-4.501, P<0.001)patients after induction chemotherapy. In N 1stage patients, the 5-year overall survival (OS) rates of patients with primary lesions achieving objective response ( n=18) and those without objective response ( n=19) after induction chemotherapy were 88.89% and 57.45%, and patients with cervical lymph node metastatic lesions achieving objective response ( n=19) and those without objective response ( n=18) were 86.72% and 49.10% respectively, with statistically significant differences ( χ2=6.023, P=0.014; χ2=7.441, P=0.006). In N 2-3stage patients, the 5-year OS rates of patients with primary lesions achieving objective response ( n=81) and those without objective response ( n=43) after induction chemotherapy were 77.56% and 50.70%, and patients with cervical lymph node metastatic lesions achieving objective response ( n=85) and those without objective response ( n=39) were 75.11% and 52.04% respectively, with significant differences ( χ2=8.037, P=0.005; χ2=7.268, P=0.007). Univariate Cox regression analysis showed that in patients with stage N 1, the tumor regression rate of primary lesions ( HR=0.048, 95% CI: 0.004-0.644, P=0.022), the efficacy of primary lesions ( HR=0.174, 95% CI: 0.037-0.830, P=0.028), the efficacy of cervical lymph node metastatic lesions ( HR=0.154, 95% CI: 0.033-0.725, P=0.017) after induction chemotherapy were significantly associated with OS; in N 2-3stage patients, the tumor regression rate of primary lesions ( HR=0.178, 95% CI: 0.056-0.564, P=0.003), the tumor regression rate of cervical lymph node metastatic lesions ( HR=0.081, 95% CI: 0.020-0.324, P<0.001), the efficacy of primary lesions ( HR=0.422, 95% CI: 0.228-0.781, P=0.006), the efficacy of cervical lymph node metastatic lesions ( HR=0.439, 95% CI: 0.238-0.813, P=0.009) after induction chemotherapy were significantly associated with OS. In multivariate Cox regression including N stage and tumor regression rate, N stage and efficacy, the interaction items were not statistically significant (all P>0.05). In T 1-2stage patients, the 5-year OS rates of patients with primary lesions achieving objective response ( n=45) and those without objective response ( n=13) after induction chemotherapy were 77.55% and 84.62%, and patients with cervical lymph node metastatic lesions achieving objective response ( n=43) and those without objective response ( n=15) were 78.89% and 80.00% respectively, with no significant differences ( χ2=0.239, P=0.625; χ2=0.005, P=0.943); in T 3-4stage patients, the 5-year OS rates of patients with primary lesions achieving objective response ( n=54) and those without objective response ( n=49) after induction chemotherapy were 78.90% and 45.00%, and patients with cervical lymph node metastatic lesions achieving objective response ( n=61) and those without objective response ( n=42) were 75.10% and 42.89% respectively, with significant differences ( χ2=13.615, P<0.001; χ2=12.752, P<0.001). Univariate Cox regression analysis showed that in patients with stage T 1-2, the tumor regression rate, the efficacy of primary lesions and cervical lymph node metastatic lesions after induction chemotherapy were not related to OS (all P>0.05); in T 3-4stage patients, the tumor regression rate of primary lesions ( HR=0.121, 95% CI: 0.033-0.444, P=0.001), the tumor regression rate of cervical lymph node metastatic lesions ( HR=0.126, 95% CI: 0.036-0.442, P=0.001), the efficacy of primary lesions ( HR=0.297, 95% CI: 0.150-0.588, P<0.001), the efficacy of cervical lymph node metastatic lesions ( HR=0.329, 95% CI: 0.173-0.625, P=0.001) after induction chemotherapy were significantly associated with OS. Multivariate Cox regression analysis showed that the interaction test of T stage and the efficacy of primary lesion trended to be statistically significant ( P=0.062). Conclusion:In patients with stage Ⅲ-ⅣA nasopharyngeal carcinoma, the responsiveness to induction chemotherapy in stage T 3-4patients has important value in predicting survival prognosis.
