ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

Objective To measure the diameter of the corpus callosum in children aged 0-14 years using midsagittal high-resolution MRI,and to find the normal reference values of the diameter of the corpus callosum in children of different ages.Methods The imaging data of 967 children with normal brain MRI were retrospectively selected and grouped according to age.The anteroposterior diameter(APD),thickness of the genu(GT),thickness of the body(BT),thickness of the isthmus(IT),thickness of the splenium(ST)and fronto-occipital diameter(FOD)of the corpus callosum were measured on the midsagittal plane of the brain.The diameters of the corpus callosum on the midsagittal plane of the brain of children at different ages were measured.The correlation analysis between the diameter of the corpus callosum and age were performed.Results The APD,GT,BT,IT,ST and FOD were positively correlated with age(r=0.660,0.590,0.528,0.521,0.660,0.597,P<0.01).The IT variation was the greatest in the subregions of the corpus callosum.The growth peak of GT and ST of corpus callosum appeared before 2 years of age.Conclusion The establishment of the normal reference value of different subregions of the corpus callosum in children can help to accurately evaluate the development of the corpus callosum,which is conducive to the evaluation of the prognosis of diseases related to the corpus callosum.

Objective To explore the perioperative safety of video-assisted thoracic surgery (VATS) in Day Care Unit and the risk factors for delayed discharge under centralized management model. Methods The patients with VATS managed by the Day Care Unit of the Drum Tower Hospital Affiliated to Nanjing University Medical School in 2021 were retrospectively collected. The patients’ postoperative data and risk factors for delayed discharge were analyzed. Results A total of 383 patients were enrolled, including 179 males and 204 females with an average age of 46.09±14.82 years. Eleven (2.87%) patients developed grade 3-4 postoperative complications during the hospitalization. Eighteen (4.70%) patients visited unscheduled outpatient clinic within 7 days, and 6 (1.57%) patients were re-hospitalized within 30 days after discharge. The remaining patients had no significant adverse events during the 30-day follow-up. The average length of hospital stay was 2.27±0.35 d. The length of hospital stay was over 48 h in 48 (12.53%) patients. The independent risk factor for delayed discharge was lobectomy or combined resection (OR=3.015, 95%CI 1.174-7.745, P=0.022). Conclusion VATS can be safely conducted under the centralized management in Day Care Unit. The risk factor for delayed discharge is the extent of surgical resection.

Objective To investigate the expressions of extracellular matrix metalloproteinase inducer(EMMPRIN),matrix metalloproteinase-9(MMP-9),lysine demethylase 6B(KDM6B)proteins and their correlation with clinicopathologic features in invasive breast cancer,and analyze the correlation among the three proteins and their value in pathological diagnosis of invasive breast cancer.Methods The surgical biopsy specimens of 124 patients with invasive breast cancer who were admitted to the Department of Pathology,the Fifth Clinical Medical College of Henan University of Chinese Medicine/People's Hospital of Zhengzhou from January 2014 to December 2017 were selected as research subjects,and 20 low-grade intraductal carcinoma tissue specimens,27 high-grade intraductal carcinoma tissue specimens,and 22 adjacent tissue specimens＞1 cm away from the invasive breast cancer were selected as controls.The expressions of EMMPRIN,MMP-9 and KDM6B proteins in cancer-adjacent tissues,low-grade intraductal carcinoma tissues,high-grade intraductal carcinoma tissues and invasive breast cancer tissues were detected by immunohistochemistry.The relationship between the relative expressions of EMMPRIN,MMP-9 and KDM6B proteins and clinicopathologic features of invasive breast cancer was analyzed,Spearman correlation analysis was used to evaluate the correlation of EMMPRIN,MMP-9 and KDM6B proteins in breast cancer tissues,and receiver operating characteristic(ROC)curve was adopted to evaluate the diagnostic value of EMMPRIN,MMP-9 and KDM6B for invasive breast cancer.Results The relative expressions of EMMPRIN and MMP-9 proteins in high-grade intraductal carcinoma and invasive breast cancer tissues were significantly higher those in cancer-adjacent tissues and low-grade intraductal carcinoma tissues,and the relative expression of KDM6B protein was significantly lower than those in cancer-adjacent tissues and low-grade intraductal carcinoma tissues(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in invasive breast cancer tissues were significantly higher those in high-grade intraductal carcinoma tissues,and the relative expression of KDM6B protein was significantly lower than that in high-grade intraductal carcinoma tissues(P＜0.05);there was no statistically significant difference in the relative expressions of EMMPRIN,MMP-9 and KDM6B proteins between cancer-adjacent tissues and low-grade intraductal carcinoma tissues(P＞0.05).The relative expressions of EMMPRIN and KDM6B proteins were not related to the age,tumor location and tumor diameter of patients with invasive breast cancer(P＞0.05),and the relative expression of MMP-9 protein was not related to the age and tumor location of patients with invasive breast cancer(P＞0.05).Relative expressions of EMMPRIN,MMP-9 and KDM6B proteins were correlated with WHO grading,lymph node metastasis,and tumor,node and metastasis(TNM)staging of invasive breast cancer(P＜0.05),and the relative expression of MMP-9 protein was correlated with the tumor diameter(P＜0.05).In the WHO grades Ⅰ,Ⅱ,and Ⅲ of invasive breast cancer,the relative expressions of EMMPRIN and MMP-9 proteins increased sequentially,while the relative expression of KDM6B protein decreased sequentially(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in the lymph node metastasis group were significantly higher than those in the non-lymph node metastasis group,and the relative expression of KDM6B protein was significantly lower than that in the non-lymph node metastasis group(P＜0.05);the relative expressions of EMMPRIN and MMP-9 proteins in TNM stages Ⅲ-Ⅳ were significantly higher than those in stages Ⅰ-Ⅱ(P＜0.05),while the relative expression of KDM6B protein was significantly lower than that in stages Ⅰ-Ⅱ(P＜0.05).In the group of invasive breast cancer with diameter≤2 cm,2 to 5 cm,and＞5 cm,the relative expression of MMP-9 protein increased sequentially(P＜0.05).Spearman correlation analysis showed that the expression of EMMPRIN was positively correlated with MMP-9 protein in invasive breast cancer tissues(r=0.990,P=0.000),the expression of EMMPRIN was negatively correlated with KDM6B protein(r=-0.606,P=0.000),and the expression of MMP-9 was negatively correlated with KDM6B protein(r=-0.612,P=0.000).ROC curve analysis showed that the area under the curve(AUC)of EMMPRIN protein for diagnosing invasive breast cancer was 0.875[95％confidence interval(CI):0.823-0.926,P＜0.05],with an optimal threshold of 10.043,sensitivity of 79.0％,and specificity of 76.8％;the AUC of MMP-9 protein in diagnosing invasive breast cancer was 0.863(95％CI:0.808-0.917,P＜0.05),with an optimal threshold of 10.070,sensitivity of 74.2％,and specificity of 76.8％;the AUC of KDM6B protein in diagnosing invasive breast cancer was 0.267(95％CI:0.196-0.338,P＜0.05),with an optimal threshold of 11.003,sensitivity of 71.0％,and specificity of 98.6％.Conclusion EMMPRIN,MMP-9 and KDM6B are related to the occurrence and development of invasive breast cancer.Detection of the expressions of EMMPRIN,MMP-9 and KDM6B is helpful to the pathological diagnosis of invasive breast cancer and clinical judgment of invasion and metastasis of breast cancer.

Objective:To investigate the efficacy of double S-shaped elastic stable intramedullary nailing in the treatment of paediatric fractures of the distal tibia diaphyseal metaphyseal junction.Methods:From January 2018 to January 2022, a total of 25 children with fracture of the distal tibia diaphyseal metaphyseal junction were treated at Department of Pediatric Orthopedics, The Second Affiliated Hospital of Inner Mongolia Medical University. All of them were treated with closed reduction and double S-shaped elastic stable intramedullary nailing. There were 16 males and 9 females with an average age of (10.4±3.3) years, and 14 left sides and 11 right sides. The operation time, imaging results and complications were recorded after operation. At the last follow-up, the American Orthopaedic Foot & Ankle Society (AOFAS) scoring was used to evaluate the efficacy.Results:Closed reduction succeeded in all patients. The operation time was (55.6±23.7) min. Follow-up lasted (20.5±4.7) months for this cohort. Bony union was achieved in all patients after (11.5±2.7) weeks. No postoperative complications occurred in the patients, like infection, loss of reduction, disparity in length of lower limbs, delayed union or non-union. The AOFAS scoring at the last follow-up yielded 23 excellent and 2 good cases, and an excellent and good rate of 100% (25/25).Conclusion:In the treatment of paediatric fractures of the distal tibia diaphyseal metaphyseal junction, double S-shaped elastic stable intramedullary nailing is a safe, effective and feasible option.

One of the most common and significant symptoms for skin disorders is pruritus.Additionally,it serves as a significant catalyst for the exacerbation or reoccurrence of skin diseases.Pruritus seriously affects patients'physical and mental health,and even the quality of life.It brings a heavy burden to the patients,the families,even the whole society.The pathogenesis and regulation mechanisms for pruritus are complicated and have not yet been elucidated.Previous clinical studies have shown that itch worsens at night in scabies,chronic pruritus,atopic dermatitis,and psoriasis,suggesting that skin pruritus may change with circadian rhythm.Cortisol,melatonin,core temperature,cytokines,and prostaglandins are the main regulatory factors of the circadian rhythm of pruritus.Recent studies have shown that some CLOCK genes,such as BMAL1,CLOCK,PER,and CRY,play an important role in the regulation of the circadian rhythm of pruritus by regulating the Janus tyrosine kinase(JAK)-signal transducer and activator of transcription(STAT)and nuclear factor kappa-B(NF-κB)signaling pathways.However,the mechanisms for circadian clock genes in regulation of circadian rhythm of pruritus have not been fully elucidated.Further studies on the mechanism of circadian clock genes in the regulation of circadian rhythm of pruritus will lay a foundation for elucidating the regulatory mechanisms for pruritus,and also provide new ideas for the control of pruritus and the alleviation of skin diseases.

Objective:Exploring the effect of recovery-oriented family psychoeducation on the level of social support and family resilience of patients with schizophrenia in remission stage, providing theoretical basis for clinical application.Methods:Using a randomized controlled trial method and convenience sampling method, 60 patients with schizophrenia in remission who visited the outpatient department of the Affiliated Mental Health Center of Shanghai Jiao Tong University School of Medicine from April 2020 to March 2022 were selected as the study subjects, and they were divided into experimental group and control group, with 30 patients in each group according to their residence places. The control group was given routine health education; the experimental group was given the rehabilitation oriented family psychoeducation, before intervention and 3 months after intervention, Social Support Rating Scale and Family Resilience Questionnaire were used to evaluate the intervention effect.Results:A total of 60 patients were included in the control group, including 13 males and 17 females, aged (27.0 ± 6.5)years.In the experimental group, there were 14 males and 16 females, aged (28.0 ± 5.6) years. After intervention, the scores of subjective support, objective support and social support utilization in Social Support Rating Scale of the experimental group were 14.33 ± 3.36, 8.43 ± 1.63 and 9.60 ± 2.49, respectively, the control group were 16.20 ± 3.83, 10.00 ± 2.59 and 8.33 ± 2.28, respectively, and the differences were statistically significant ( t=2.00, 2.80, -2.05, all P<0.05). After intervention, the total score of Family Resilience Questionnaire and the scores of perseverance, support and harmony were 78.77 ± 9.61, 24.90 ± 3.07, 15.10 ± 2.23 and 23.63 ± 3.04, respectively. Higher than the control group 72.67 ± 15.96, 23.43 ± 4.92, 14.03 ± 3.60, 21.13 ± 5.13, the differences were statistically significant ( t values were -2.29--1.37, all P<0.05). Conclusions:Recovery-oriented family psychoeducation can improve the level of social support and family resilience of schizophrenia patients in remission.

Objective:To explore therapeutic efficacy and mechanism of puerarin(PUE)in treating of ulcerative colitis(UC).Methods:Network pharmacology and molecular docking technique were used to screen and analyze targets of PUE in regulating UC.C57BL/6 mice were given free access to 2.5%DSS aqueous solution for 7 days,and influence of PUE on changes in body weight and disease activity index(DAI)score were subsequently observed.Histopathological alterations of colon tissue were observed by HE staining,changes of goblet cell population in colon tissue were evaluated through Alcian blue staining;expressions of inflammatory factors in colon tissue were detected by qRT-PCR and ELISA.Effect of PUE on MODE-K cell viability and apoptosis were assessed by CCK-8 and flow cytometry.Results:A total of 38 common targets of PUE in modulating UC,such as AKT1,TNF,STAT3,CASP3,HIF1A and etc,mainly involving TNF,IL-17 and PI3K-Akt signaling pathway.In vivo experiments confirmed that PUE ameliorated degree of colon shortening,body weight and DAI scores and reduced inflammatory cell infiltration in mice.Besides,expressions of inflammatory factors in colon,such as TNF-α and IL-1β,were inhibited by PUE.Furthermore,in vitro experiments validated that PUE relieved DSS-induced apoptosis of epithelial cells.Conclusion:PUE alleviates occurrence and development of DSS-induced UC in mice.

Objective:To translate the Pediatric Epilepsy-Specific Health-Related Quality of Life (PedsQL TM Epilepsy Module) into Chinese and test its reliability and validity in children aged 5 to 7 years old and their parents. Methods:Brislin translation model was used for forward translation, back translation, harmonization, and proofreading of the PedsQL TM Epilepsy Module. Chinese version of PedsQL TM Epilepsy Module beta version was developed through cognitive interviews, expert consultations, and pre-surveys for cross-cultural adaptation of the scale. From April to November 2023, convenience sampling was used to select 420 children with epilepsy and their parents admitted to the Children's Hospital of Soochow University as participants for a questionnaire survey to test its reliability and validity. Results:A total of 840 questionnaires were distributed (420 for children and 420 for parents), and 394 valid questionnaires were collected from children and 400 valid questionnaires were collected from parents, and the effective response rates of the questionnaires were 93.81% (394/420) and 95.24% (400/420), respectively. Chinese version of PedsQL TM Epilepsy Module (child report version) included five dimensions and 28 items. Chinese version of PedsQL TM Epilepsy Module (parent agent report version) consisted of five dimensions and 29 items. The content validity indices at the item level were 0.800 to 1.00, while the content validity indices at the scale level were 0.978 and 0.979, respectively. Exploratory factor analysis of two versions of the scale showed that five common factors were extracted, with cumulative variance contribution rates of 64.557% and 75.205%, respectively. Confirmatory factor analysis showed that the models of the two scales fitted well. The total Cronbach's α coefficients of the two scales were 0.906 and 0.914, respectively, with Cronbach's α coefficients for each dimension ranging from 0.869 to 0.991. The total test-retest reliability coefficients of the scale were 0.998 and 0.995, respectively, and the test-retest reliability coefficients of each dimension were 0.803 to 0.995. Conclusions:Chinese version of the PedsQL TM Epilepsy Module has good reliability and validity, and is suitable for evaluating the health-related quality of life of children with epilepsy aged 5 to 7 years old in China.
