Objective To study the therapeutic effect of Xuefu Zhuyu Capsule combined with sacubitril valsartan on dilated cardiomyopathy.Methods A total of 70 patients with dilated cardiomyopathy who were hospitalized in the Hospital from January to December 2020 were selected as the research objects and random-ly divided into control group and experimental group,with 35 cases in each group.The control group was only treated with sacubitril valsartan,and the experimental group was treated with Xuefu Zhuyu Capsule combined with sacubitril valsartan.According to the patient's blood pressure and renal function,sacubitril valsartan was titrated from a small dose to the maximum dose.Xuefu Zhuyu Capsule was uesd 2.4 g each time,twice a day,and the treatment time was three months.The symptoms of heart failure,glycosylated hemoglobin(HbA1c),low density lipoprotein(LDL),total cholesterol(TC),triglyceride(TG),ALT,AST,N-terminal pro-brain natriuretic peptide(NT-proBNP),left ventricular end-systolic diameter(LVEDd),left ventricular end-dias-tolic diameter(LVEDs),ejection fraction(EF)and the incidence of arrhythmia were observed in the two groups after treatment.Results After treatment,the level of NT-proBNP in the experimental group was sig-nificantly lower than that in the control group(P＜0.05).There was no significant difference in LDL,TC,TG,LVEDd,LVEDs and EF between the two groups(P＞0.05).The incidence of atrial tachycardia and ven-tricular premature beat in the experimental group was higher than that in the control group(P＜0.05).Con-clusion Xuefu Zhuyu Capsule combined with sacubitril valsartan can significantly improve the symptoms of patients with heart failure and reduce the level of NT-proBNP,but it may increase the proportion of patients with atrial tachycardia and ventricular premature beats.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Background::Carotid intima-media thickness (IMT) and diameter, stiffness, and wave reflections, are independent and important clinical biomarkers and risk predictors for cardiovascular diseases. The purpose of the present study was to establish nationwide reference values of carotid properties for healthy Chinese adults and to explore potential clinical determinants.Methods::A total of 3053 healthy Han Chinese adults (1922 women) aged 18-79 years were enrolled at 28 collaborating tertiary centers throughout China between April 2021 and July 2022. The real-time tracking of common carotid artery walls was achieved by the radio frequency (RF) ultrasound system. The IMT, diameter, compliance coefficient, β stiffness, local pulse wave velocity (PWV), local systolic blood pressure, augmented pressure (AP), and augmentation index (AIx) were then automatically measured and reported. Data were stratified by age groups and sex. The relationships between age and carotid property parameters were analyzed by Jonckheere-Terpstra test and simple linear regressions. The major clinical determinants of carotid properties were identified by Pearson’s correlation, multiple linear regression, and analyses of covariance.Results::All the parameters of carotid properties demonstrated significantly age-related trajectories. Women showed thinner IMT, smaller carotid diameter, larger AP, and AIx than men. The β stiffness and PWV were significantly higher in men than women before forties, but the differences reversed after that. The increase rate of carotid IMT (5.5 μm/year in women and 5.8 μm/year in men) and diameter (0.03 mm/year in both men and women) were similar between men and women. For the stiffness and wave reflections, women showed significantly larger age-related variations than men as demonstrated by steeper regression slopes (all P for age by sex interaction <0.05). The blood pressures, body mass index (BMI), and triglyceride levels were identified as major clinical determinants of carotid properties with adjustment of age and sex. Conclusions::The age- and sex-specific reference values of carotid properties measured by RF ultrasound for healthy Chinese adults were established. The blood pressures, BMI, and triglyceride levels should be considered for clinical application of corresponding reference values.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Objective:To explore the correlation between middle cerebral artery (MCA) pulsatility index (PI) and total magnetic resonance imaging (MRI) burden in elderly patients with cerebral small vessel diseases (CSVD).Methods:A total of 203 CSVD inpatients aged 60 years and above who were hospitalized in the Department of Neurology of Hebei General Hospital from March 2017 to December 2020 were enrolled. The clinical data, transcranial Doppler ultrasound parameters and brain MRI data were collected. According to the total burden score, the patients were divided into low burden group (0-1 point) and high burden group (2-4 points). Univariate and multivariate Logistic regression analysis was used to analyze the correlation between MCA PI and total MRI burden in the elderly patients with CSVD. Subsequently, the receiver operating characteristic curve was used to evaluate the value of MCA PI for predicting the high MRI burden of CSVD in the elderly.Results:Hypertension ( OR=2.569, 95% CI 1.068-6.182, P=0.035), systolic blood pressure ( OR=1.033, 95% CI 1.006-1.061, P=0.016), creatinine ( OR=1.044, 95% CI 1.009-1.079, P=0.013) and MCA PI ( OR=1.125, 95% CI 1.087-1.166, P<0.001) were independently correlated with the increasing total MRI burden in the elderly patients with CSVD. Spearman rank correlation analysis revealed that there was strong and positive correlation between MCA PI and high MRI burden in the elderly patients with CSVD ( r=0.65, P<0.001). The analysis showed that when the cut-off for MCA PI was 1.11, it could identify high MRI burden of CSVD in the elderly. The area under the curve was 0.908 (95% CI 0.864-0.953, P<0.001). The sensitivity and specificity were 0.852 and 0.880, respectively. The positive predictive value was 92.38%, and the negative predictive value was 77.70%. Conclusion:The MCA PI is positively correlated with total MRI burden in the elderly patients with CSVD, and has a higher value in predicting the total MRI burden in the elderly CSVD patients, which probably bring brighter prospects for its clinical application.

ObjectiveTo investigate effect of conducting training of autism spectrum disorder （ASD） early screening skill on improving the ability to early identify ASD of medical staffs in primary care hospitals. MethodsIn September 2021， the training of ASD early screening skills was carried out for medical staffs from 20 primary care hospitals in Chengdu. After training， the training effect was evaluated. The numbers of referrals from primary care hospitals to superior hospitals， confirmed ASD as well as their average diagnostic age of children with ASD before and after training were used as evaluation indicators. ResultsAfter training， the number of children with suspected ASD referred by primary care hospitals was more than that before training ［（16.65±11.60） vs. （3.40±2.23）， t=5.431， P<0.01］， the number of children diagnosed with ASD was more than that before training［（6.85±4.93） vs. （2.45±1.67）， t=4.171， P<0.01］， and the differences were statistically significant. As for the diagnosed age of ASD children， after training， the average age was lower than that before training ［（34.95±11.67） vs. （42.2±14.64）， t=-2.553， P=0.019］. ConclusionTraining of ASD early screening skills for medical staffs in primary care hospitals may help to improve their ability to early screening ASD children.

Objective:To systematically evaluate the risk factors for postoperative pulmonary complications (PPCs) in elderly patients undergoing hip fracture surgery.Methods:PubMed, Embase, Cochrance Library, CBM, CNKI and Wanfang Databases were searched.Search strategy was subject word combined with random word.The case control and cohort studies involving the influencing factors for PPCs in elderly patients undergoing hip fracture from January 2000 to November 2020 were retrieved.PPCs included pneumonia, aspiration pneumonitis, pulmonary infections, respiratory failure, atelectasis and pleural effusion, etc.The quality of literatures was assessed by using Newcastle-Ottawa Scale, data were extracted and analysis was performed using RevMan5.3 software.Results:A total of 18 studies were finally enrolled, including 15 case control studies and 3 cohort studies.The results of analysis showed that the advanced age, male, history of smoking, low body mass index, history of cerebrovascular accident, history of chronic obstructive pulmonary disease, history of diabetes, preoperative albumin concentration<35 g/L, preoperative hemoglobin concentration<120 g/L, American Society of Anesthesiologists Physical Status classification≥Ⅲ, operation delay≥48 h and general anesthesia were the risk factors for PPCs ( P<0.05). Conclusions:There are numerous risk factors for PPCs in elderly patients undergoing hip fracture surgery, and advanced age, male, history of smoking, low body mass index, history of cerebrovascular accident, history of chronic obstructive pulmonary disease, history of diabetes, preoperative albumin concentration<35 g/L, preoperative hemoglobin concentration<120 g/L, American Society of Anesthesiologists Physical Status classification≥Ⅲ, operation delay≥48 h and general anesthesia are the risk factors for PPCs in elderly patients undergoing hip fracture surgery.

Insufficient remyelination due to impaired oligodendrocyte precursor cell (OPC) differentiation and maturation is strongly associated with irreversible white matter injury (WMI) and neurological deficits. We analyzed whole transcriptome expression to elucidate the potential role and underlying mechanism of action of lipocalin-2 (LCN2) in OPC differentiation and WMI and identified the receptor SCL22A17 and downstream transcription factor early growth response protein 1 (EGR1) as the key signals contributing to LCN2-mediated insufficient OPC remyelination. In LCN-knockdown and OPC EGR1 conditional-knockout mice, we discovered enhanced OPC differentiation in developing and injured white matter (WM); consistent with this, the specific inactivation of LCN2/SCl22A17/EGR1 signaling promoted remyelination and neurological recovery in both atypical, acute WMI due to subarachnoid hemorrhage and typical, chronic WMI due to multiple sclerosis. This potentially represents a novel strategy to enhance differentiation and remyelination in patients with white matter injury.

Objective:To describe the spectral-domain optical coherence tomography (SD-OCT) features of retinal tuft.Methods:A retrospective clinical study. From May 2019 to April 2020, 22 patients (22 eyes) diagnosed as retinal tuft by clinical fundus examination in Eye Hospital of Wenzhou Medical University at Hangzhou were included in the study. There were 9 eyes in 9 males and 13 eyes in 13 females. All patients underwent ultra-widefield laser scanning fundus photography and SD-OCT examination. SD-OCT was performed with a 55° wide-angle lens to observe the morphology, color, size and location of the lesions.Results:Twenty-six retinal tuft lesions were found in 22 eyes, all of which were solitary, gray, thylakoid and protrusion. SD-OCT images showed that all the lesions of retinal tuft showed a local protuberant appearance with moderate and hyperreflectivity, which was higher than the surrounding retina plane. In 22 lesions (84.62%, 22/26), there were one or more irregular hyporeflective cavities between the retinal neuroepithelial layers, and the other 4 lesions (15.38%,4/26) contained no hyporeflective cavities. In addition, 23 cases (88.46%, 23/26) with hyperreflective condensed cortical vitreous attached to the retina at the top of lesions, 8 cases (30.77%, 8/26) with retinal tear, and 6 cases (23.08%, 6/26) with shallow retinal detachment.Conclusions:In SD-OCT, the retinal tufts show moderate and strong local protrusion, which are higher than the surrounding retinal plane. In most of the lesions, there are multiple or single irregular weak reflex cavities, and there are hyperreflective condensed cortical vitreous attached to the retina at the top of lesions. Local retinal tears or shallow retinal detachment are present in some lesions.
