BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

Objective　To analyze the clinical characteristics and prognostic factors for clinical cure in chronic hepatitis B virus (HBV) infected patients with pegylated interferon-α-2b (PEG-IFN-α-2b) based therapy. Methods　This is a retrospective study. Chronic HBV infected patients receiving PEG-IFN-α-2b therapy were enrolled in Yuncheng Central Hospital affiliated to Shanxi Medical University between August 2020 and November 2023. Treatment-naïve patients received PEG-IFN-α-2b monotherapy, while nucleoside (acid) analogs (NAs)-experienced patients received PEG-IFN-α-2b add-on therapy. The study endpoint was hepatitis B surface antigen (HBsAg) negative in accompany with HBV DNA below the detection limit (course of treatment < 48 weeks) or treatment for 48 weeks. The general characteristics, virological variables, blood routine test, and liver function of patients were collected at baseline and study endpoint. Student’s t test or Mann-Whitney U test was used for comparison. The prognostic factors of clinical cure were examined using univariate and multivariate stepwise logistic regression models. Results　A total of 61 chronic HBV infected patients were enrolled, including 39 males and 22 females. The age were (39.13±7.53) years. Twenty-one cases were treatment-naïve, while 40 patients were NAs-experienced. Nineteen cases were positive for HBV DNA at baseline. The baseline HBsAg levels were 211.30(50.93, 2 110.00) IU/mL. Thirty-four patients achieved clinical cure at the study endpoint with 25.50 weeks of median course of PEG-IFN-α-2b treatment. Twenty-seven patients did not achieve clinical cure at the study endpoint, and the course of treatment was 48 weeks. Clinical cure group had significant lower baseline HBsAg level when compared with non-clinical cure group [78.66(19.54, 204.60) IU/mL vs 2 078.00(442.20, 4 237.00) IU/mL, P<0.001]. At the study endpoint, the white blood cell, platelet, red blood cell, hemoglobin levels were lower than those in baseline (P<0.05), while alanine aminotransferase and asparatate aminotransferase levels were higher than those in baseline (P<0.05). There were no remarkable differences in blood routine tests or liver function between clinical cure and non-clinical cure group at either baseline or study endpoint (P>0.05). Baseline low HBsAg level was a predictor for clinical cure in patients receiving PEG-IFN-α-2b therapy (OR=0.998, 95%CI: 0.998-0.999). No severe adverse events were happened during therapy. Conclusion　PEG-IFN-α-2b-based therapy was well-tolerant, and could achieve high rate of clinical cure in chronic HBV-infected patients who had low baseline HBsAg level.

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.

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 investigate the antibacterial and osteogenic properties of biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants.Methods:After the fiber network structure of sodium hydrogen titanate was constructed by alkali thermal reaction on the surface of Ti6Al4V (noted as AT), it was biomimetically mineralized in the modified simulated body fluid to form a micro-nano topology with high specific surface area (noted as AT-CaP), and finally loaded with PVPI to construct a novel antibacterial osseointegration coating (noted as AT-CaP-PVPI). The study was conducted in AT, AT-CaP, and AT-CaP-PVPI groups, in each of which 3 parallel experiments were performed. The morphology and colony counting of Staphylococcus aureus on the coating surface were observed to detect the in vitro antibacterial performance of the coating. Fifteen male SD rats were randomly divided into 3 groups ( n=5): AT, AT-CaP, and AT-CaP-PVPI. After intramedullary injection of Staphylococcus aureus into the lower end of the femur in the SD rats, titanium rods coated with AT, AT-CaP, and AT-CaP-PVPI were inserted into the marrow cavity. The osteogenesis, volume ratio of new bone mass and number of trabeculae on the surface of the femoral implants were compared between the 3 groups 4 weeks after operation. Results:In AT and AT-CaP groups, a large number of bacteria grew in their inherent elliptical or spherical shape on the implant surface and a large number of colonies were seen on the plate; in AT-CaP-PVPI group, the bacteria on the coating surface exhibited membrane deformation and depression, some of them were completely broken and dissolved, and a large number died. There was almost no new bone formation around the implants in AT group; new bone scattered around the implants with discontinuous distribution in AT-CaP group; a great amount of new bone was seen around the implants with even distribution but no signs of infection in AT-CaP-PVPI group. The volume ratio of new bone mass and the number of trabeculae on the implant surface in AT-CaP-PVPI group were 0.453±0.206 and 6.055±0.536, respectively, significantly higher than those in AT group (0.046±0.028 and 1.667±1.249) and AT-CaP group (0.188±0.052 and 3.804±0.889) ( P<0.05). Conclusion:Biomimetic mineralized iodine-loaded coating with micro-nano topography on the surface of bone implants shows good antibacterial and osteogenic properties.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Objective To investigate the related factors of citrin deficiency(CD)complicated with liver failure(LF).Methods A retrospective analysis was performed on 91 patients with CD admitted to the department of pediatrics of Fujian Children's Hospital and Fujian Maternity and Child Health Hospital from January 2011 to August 2022,including 28 patients with LF(LF group)and 63 patients without LF(non-LF group).The general information of the patients(gender,age,body weight,feeding method and whether they were co-infected,whether they had light-colored stool,whether they had congenital heart disease,and whether they were accompanied by hepatomegaly)and laboratory indicators of the patients[white blood cell count(WBC),neutrophil count(NEU),hemoglobin(Hb),platelet count(PLT),C-reactive protein(CRP),blood lactic acid(Lac),blood ammonia,blood sodium,blood potassium,alanine aminotransferase(ALT),aspartate aminotransferase(AST),γ-glutamyl transpeptides(γ-GGT),total bilirubin(TBil),direct bilirubin(DBil),albumin,alkaline phosphatase(ALP),bile acid,cholesterol,uric acid,MB isoenzyme of creatine kinase(CK-MB),blood glucose(GLU),prothrombin time(PT),international standard normalized ratio(INR)were collected.The above indicators in two groups were compared,and the indicators with statistically significant differences in univariate analysis were included in Logistic regression analysis to find the correlated factors of CD complicated with LF.The predictive value of each related factor for CD complicated with LF was analyzed by drawing receiver operator characteristic curve(ROC curve).The area under the ROC curve(AUC)was used to evaluate the prediction efficiency of each factor.Results Compared with non-LF group,the patients in LF group had higher proportion of infections(60.7%vs.12.7%),higher TBil[μmol/L:242.50(210.95-278.68)vs.168.20(141.50-232.65)]and DBil[μmol/L:146.40(100.73-173.55)vs.79.40(65.39-99.60)],lower Hb(g/L:79.21±20.39 vs.94.75±12.56),PLT(×109/L:215.61±148.73 vs.377.63±163.00)and GLU(mmol/L:2.79±1.32 vs.4.10±1.36),worse prognosis[mortality:15.0%(3/28)vs.0.0%(0/63)],the differences were statistically significant(all P＜0.05).Logistic regression multi-factor analysis showed infections[odds ratio(OR)=5.160,95%credibility interval(95%CI)was 1.006-26.455,P = 0.049],decreased Hb(OR = 0.930,95%CI was 0.869-0.996,P = 0.037),decreased PLT(OR = 0.992,95%CI was 0.987-0.998,P = 0.009),decreased GLU(OR = 0.355,95%CI was 0.174-0.724,P = 0.004)and increased TBil(OR = 1.016,95%CI was 1.001-1.030,P = 0.034)were the related factors of CD complicated with LF.ROC curve analysis showed that Hb,PLT,GLU,TBil and the combined diagnosis had certain predictive value for CD complicated with LF[AUC and 95%CI were 0.754(0.639-0.868),0.756(0.646-0.867),0.749(0.644-0.854),0.807(0.717-0.898)and 0.944(0.897-0.992),respectively,all P = 0.000],among them,the combined diagnostic efficiency was the highest.When the best cut-off values of Hb,PLT,GLU and TBil were 86.50 g/L,254.50×109/L,3.29 mmol/L and 185.40 μmol/L,the sensitivity of Hb,PLT,GLU and TBiL were 74.6%,81.0%,76.2%and 96.4%,respectively,the specificity were 71.4%,63.3%,64.3%and 65.1%,respectively.Conclusion Infections,decreased Hb,PLT,GLU and increased TBil are the related factors associated with LF in CD,and combined diagnosis can improve the diagnostic efficiency.

Objective:To verify the prognostic significance of the tumor regression grade (TRG) for muscle-invasive bladder cancer (MIBC) patients undergoing radical cystectomy (RC) after neoadjuvant chemotherapy.Methods:The data of 70 MIBC patients treated with gemcitabine combined with cisplatin neoadjuvant chemotherapy and RC in Sun Yat-sen University Cancer Center between July 2016 to November 2021 were retrospectively reviewed. There were 65 males and 5 females, with an average age(59.79±10.56)years old. The patients accepted transurethral resection of bladder tumor (TURBT) specimens before neoadjuvant chemotherapy. Clinicopathological characteristics of patients were recorded and TRG was assessed. TRG evaluation criteria: TRG 1 was defined as no cancer residue, TRG 2 was defined as the proportion of residual cancer area to tumor bed area <50%, and TRG 3 was defined as the proportion of residual cancer area to the area of the tumor bed ≥ 50%. Chi-square test or Fisher's exact test were used to compare the relationship between patients' clinicopathological characteristics and TRG. The relationship between post-neoadjuvant therapy tumor and node(ypTN)stage, and survival, including overall survival(OS)and recurrence-free survival (RFS) were analyzed by Kaplan-Meier analysis. The pathologically locally descending disease was defined as (ypT < T 2 and ypN=N 0) and pathologically locally advanced disease was defined as (ypT≥T 2 and/or ypN ≥N 1). Cox regression was used for univariate and multivariate analysis of OS and RFS. Results:Chi-square test or Fisher exact test analysis showed TRG was significantly associated with ypT stage ( P < 0.001), ypN stage ( P = 0.002), lympho-vascular invasion ( P<0.001) and variant histology ( P<0.001). The OS of patients with TRG 1, TRG 2 and TRG 3 were 20.5(10.3, 31.8), 17.0(11.0, 30.8)and 15.0(11.0, 26.0) months, respectively, and the difference was significantly different( P = 0.037). The RFS of patients with TRG 1, TRG 2 and TRG 3 were 15.0(8.3, 25.5), 15.0(8.0, 27.0)and 11.0(4.5, 25.5) months, respectively, and the difference was significantly different ( P=0.029). There were significant differences between patients with pathologically locally descending disease and locally advanced disease in OS [18.5(10.3, 30.8)vs.15.0(11.0, 27.3)months, P = 0.013] and RFS [14.0(8.0, 24.0)vs. 11.5(8.0, 26.8)months, P = 0.012]. Among patients with locally advanced pathology, the OS was 19.5(11.0, 32.5)months for patients with TRG ≤2, 13.5(10.8, 26.0)months for patients with TRG 3( P=0.140). The RFS was 12.0(8.0, 31.0)months for those patients with TRG ≤2 and 11.0(6.0, 26.0)months for those patients with TRG 3( P = 0.180). Cox univariate analyses showed that patients with TRG 3 were associated with decreased OS ( HR = 6.043, 95% CI 1.170-31.213, P = 0.032) and RFS ( HR = 6.354, 95% CI 1.231-31.802, P = 0.027). Conclusions:This study showed that TRG was correlated with OS and RFS among patients. The patients who had the higher TRG had the worse prognosis. It was confirmed that TRG predicted the prognosis of patients undergoing radical cystectomy after neoadjuvant chemotherapy. Therefore, TRG assessment is recommend in pathology report for patients who had radical cystectomy after neoadjuvant chemotherapy.

Objective:To report pediatric endoscopic retrograde cholangiopancreatography (ERCP) intubation techniques and to analyze the influencing factors of pediatric ERCP in China.Methods:Retrospective analysis was performed on 90 cases of pediatric and adult ERCP operations respectively at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2016 to June 2020. The anatomic data, intubation time, and endoscopic intubation measures were reviewed. The anatomic differences in duodenal papilla between the children and adults were analyzed to find the factors affecting ERCP intubation time in children.Results:There were 88 cases of successful infantile intubation with the success rate of 97.8%, and 90 cases of successful adult intubation with the success rate of 100.0%. The intubation time in the pediatric group was 187±67 s, and that in the adult group was 247±86 s with significant difference ( t=5.220, P<0.001). The duodenal diameter of pediatric patients was 3.38±1.57 cm, and that of adult patients was 5.94±1.87 cm with significant difference ( t=9.832, P<0.001). The horizontal distance from the duodenal bulb to the papilla in pediatric patients was 2.44±1.15 cm, which was significantly shorter than 4.22±1.43 cm in adult patients ( t=9.077, P<0.001). Most duodenal papillae in children were hemispherical [flat 26.1% (23/88), hemispherical 51.1% (45/88), cylindrical 22.7% (20/88)], while most of those in the adult patients were cylindrical [flat 9.1% (8/88), hemispherical 23.9% (21/88), cylindrical 67.0% (59/88)]. The factors influencing the intubation time of ERCP in children by univariate analysis included the shape of duodenal papilla, duodenal papilla hardness, visual region, distance from junction of duodenal bulb and descending part to duodenal papilla, distance from duodenal papilla to endoscope, and degree of incising. Conclusion:Shorter and stiffer duodenal papillae in children with normal papilla orientation are associated with shorter intubation time. These indicators are favorable factors for intubation.
