Objective:To investigate the efficacy of anatomical resection (AR) in the early stages of treating solitary hepatocellular carcinoma (HCC) combined with liver cirrhosis with a diameter of ≤5 cm in comparison to different surgical methods of preferential hepatic parenchymal preservation (non-anatomical liver resection, NAR).Methods:The clinical data of 1 390 cases with solitary HCC combined with liver cirrhosis at an early stage who underwent liver resection at Mengchao Hepatobiliary Hospital of Fujian Medical University and six other medical centers from September 2013 to May 2019 were retrospectively analyzed. Patients were divided into the AR group (486 cases) and the NAR group (904 cases) and the wide surgical margin (WSM) group (745 cases) and the narrow surgical margin (NSM) group (645 cases) according to whether they received AR and the width of the surgical margin (1 cm). The basic information of the patients, preoperative evaluation index data, and postoperative follow-up (follow-up every 3 months) were collected. The Kaplan-Meier method was used to plot the survival curve.The log-rank test was used to compare the difference in survival between the two groups. The Cox proportional hazards regression model was used to analyze the factors affecting the prognosis. Propensity score matching (PSM) was applied to reduce intergroup bias.Results:The overall survival (OS) rates for all patients at 1, 3, and 5 years were 95.5%, 79.9%, and 63.5%, respectively. The recurrence-free survival (RFS) rates were 81.5%, 59.0%, and 43.7%, respectively. There was a statistically significant difference in RFS rate between the AR group and the NAR group prior to PSM, but no statistically significant difference in OS rate (RFS rate: 47.0% vs. 41.9%, P<0.05; OS rate: 64.4% vs. 62.9%, P>0.05). The postoperative RFS rate and OS rate were significantly superior in the WSM group than those of the NSM group (RFS rate: 47.8% vs. 37.2%, P<0.001; OS rate: 69.0% vs. 57.3%, P<0.001). There was no statistically significant difference in OS rate and RFS rate between the AR group and the NAR group following PSM (RFS: 46.3% vs. 45.1%, P>0.05; OS rate: 64.0% vs. 64.3%, P>0.05).The 5-year OS and RFS rates in the WSM group were 66.8% and 60.2%, respectively. The 5-year OS and RFS rates for the NSM group were 48.7% and 41.4%, respectively, with a statistically significant difference ( P<0.05). Cox multivariate analysis indicated that serum albumin, tumor diameter, microvascular invasion, and surgical margin were independent prognostic factors affecting OS and RFS. The Child-Pugh grade and satellite lesions were independent prognostic factors affecting OS. Conclusion:Anatomical liver resection is not an independent risk factor for prognosis, but the state of the resection margin determines the prognosis of patients with solitary HCC combined with cirrhosis. Therefore, hepatic resection margins should be prioritized in such patients.

Objective To explore the diagnostic significance of fecal calprotectin(FC)in infectious diarrhea in children.Methods A total of 190 children with infectious diarrhea who were hospitalized in Hangzhou Children's Hospital from August 2021 to July 2024 were selected and divided into bacterial group(115 cases)and viral group(75 cases)according to type of pathogen.48 children who underwent health examination in the hospital during the same period were included in control group.The FC,white blood cell count(WBC),C-reactive protein(CRP),and procalcitonin(PCT)of three groups of children were detected.The diagnostic efficacy of FC,WBC,CRP and PCT for bacterial infectious diarrhea was evaluated by using the receiver operating characteristic(ROC)curve.Results The proportions of fever and hematochezia,the highest body temperature,frequency of defecation,and fecal white blood cells in bacterial group were significantly higher than those in viral group,while the proportion of vomiting was significantly lower than that in viral group(P＜0.05).There were statistically significant differences in levels of WBC,CRP,PCT and FC among three groups of children(P＜0.05),and the levels were all in the order of bacterial group＞viral group＞control group.The results of ROC curve showed that area under the curve(AUC)of FC for diagnosing bacterial diarrhea was 0.941,with a sensitivity of 87.0％and a specificity of 85.4％.The AUC,sensitivity and specificity of the diagnosis by FC combined with CRP were 0.987,93.0％and 97.9％respectively.Correlation analysis indicated that FC was positively correlated with WBC and CRP levels(r-0.221,0.159,P＜0.05).Conclusion FC is helpful in differentiating bacterial diarrhea from viral diarrhea,and the combined detection of FC and CRP can effectively improve the effectiveness of differential diagnosis and reduce the misdiagnosis rate.

Therefore, hepatic resection margins should be prioritized in such patients.

Objective To investigate the positive detection and epidemic characteristics of enter ovirus(EV),the pathogen of hand-foot-mouth disease(HFMD),in Hangzhou,and to provide scientific basis for formulating prevention and control strategies of HFMD in the future.Methods From January 2016 to December 2022,14 259 positive cases of enterovirus universal nucleic acid detected in Hangzhou Children's Hospital were collected and analyzed retrospectively by age,gender,detection time and other factors.Results The average positive detection rate of EV was 45.48%(14 259/31 354),among which the positive detection rate of boys was 27.20%and that of girls was 18.28%,the difference was statistically significant(P<0.01).The positive detection rate of EV in children of different ages decreased with the increase of age,and the positive detection rate of EV in children under 5 years old accounted for 90.38%of all positive children.Seasonally,enteroviruses were detected throughout the year,but the incidence was high in summer,and the total positive number from May to July accounted for 49.16%of the total detected number.In terms of year,the positive detection rate of EV has shown a downward trend year by year since 2016.Conclusion There are gender differences in enterovirus infection in Hangzhou,and boys are more susceptible to enterovirus infection,especially children under 5 years old need to pay attention to EV protection.In addition,HFMD has a certain seasonality,with a high incidence in summer,and the annual detection rate has declined year by year since 2016,which may be related to the promotion of vaccines and the improvement of health awareness.

Objective To explore the influence of impulsivity on digital addiction tendencies in patients with Wilson disease(WD)and its related factors.Methods A total of 66 patients with WD were included in the study which were divided into neurological WD group(42 cases)and hepatic WD group(24 cases)according to clinical manifestations.Sixty-six WD patients were included as the study subjects,including 24 cases of hepatic WD and 42 cases of neurological WD.The Chinese version of the Barratt impulsiveness scale(BIS-11-C)was used to assess patients'impulsiveness.Mobile phone addiction index(MPAI)evaluates the degree of dependence on mobile phone use.Cranial MRI was used to examine the location and cumulative frequency of the diseased brain region.Results Among the 66 WD patients,45 cases(68.2% )had the tendency of digital addiction,including 35 cases(53.0% )in the neurological WD group and 10 cases(15.2% )in the hepatic WD group.There was a statistically significant difference in the proportion of the two types of WD patients(P=0.001).The scores of BIS-11-C and MPAI scales in neurological WD group were higher than those in hepatic WD group(P<0.05).The out-of-control score in the MPAI scale is positively correlated with the attention impulsivity score(r=0.499,P=0.001),motor impulsivity score(r=0.553,P=0.001),unplanned impulsivity score(r=0.535,P=0.001),and impulse control score(r=0.653,P=0.001)in the BIS-11-C scale.Linear regression analysis showed a correlation between attention impulsivity score and frontal lobe lesions(B=-1.634,P=0.018).There was a correlation between loss of control score and frontal lobe lesions(B=-3.609,P=0.023).The withdrawal score was associated with the thalamus lesions(B=-5.047,P=0.007)and frontal lobe lesions(B=-2.204,P=0.024).Avoidance score was associated with parietal lobe lesions(B=-1.867,P=0.032).The low efficacy score was associated with the putamen lesions(B=-1.789,P=0.016)and frontal lobe lesions(B=-1.592,P=0.044).Conclusion Neurological WD patients have higher tendency of digital addiction than hepatic WD patients and the tendency of digital addiction is related to impulsivity.The digital addiction tendency of WD patients may be related to impulse control disorders caused by lesions in multiple brain regions such as the putamen,thalamus,and frontal lobe.

Freezing of gait is a common gait disorder in Parkinson disease (PD), which is highly disabling, situational and therapeutically challenging. At present, there is no clear and effective intervention method. In recent ten years, exercise training based on cognitive-motor dual tasks has been more and more used in the intervention treatment of freezing of gait of PD patients, and achieved certain clinical results. The muscle-brain crosstalk effect of exercise training promoting muscle secretory factors is crucial for freezing of gait rehabilitation of PD. There are differences in the effects of cognitive-motor dual tasks of different types and loads on gait, but the specific training types and loads and mechanism of action still need to be further elucidated. This paper focuses on the research progress of muscle-brain crosstalk mechanism in cognitive-motor interference effect of freezing of gait in PD patients, aiming to providing a new theoretical perspective for clinical cognitive-motor training intervention of freezing of gait in PD patients.

Objective:To investigate the value of cellular immune status before initial 131I treatment for predicting treatment response in young and middle-aged patients with papillary thyroid cancer (PTC). Methods:From March 2018 to April 2019, 150 young and middle-aged patients with PTC (46 males, 104 females, age (40.0±9.8) years) who underwent total thyroidectomy and neck lymph node dissection in the Affiliated Hospital of Qingdao University were enrolled retrospectively. All patients underwent radioablation 1-2 months after operation, and the serum lymphocyte subsets (CD3 + , CD4 + , CD8 + , CD4/CD8) as well as natural killer (NK) cells were detected 1 d before the initial 131I treatment. Patients were divided into excellent response (ER) group and non-ER group according to the response of 6-12 months after 131I treatment. Clinicopathological characteristics, preablative stimulated thyroglobulin (psTg), initial 131I dose and lymphocyte subsets that might affect the response to 131I treatment were analyzed (independent-sample t test, Mann-Whitney U test, χ2 test, multiple logistic regression analysis). ROC curve analysis was used to evaluate the predictive value of significant factors for non-ER. Results:Of 150 patients, 84 cases were in ER group (56.00%), and 66 cases (44.00%) were in non-ER group. Age ( z=-2.86, P=0.004), M stage ( χ2=13.64, P<0.001), psTg ( z=-8.94, P<0.001), initial 131I dose ( z=-7.60, P<0.001), CD4 + ( t=2.50, P=0.014), CD4/CD8 ( z=-2.22, P=0.027) of the two groups were significantly different. Multivariate analysis showed that psTg (odds ratio ( OR)=1.27, 95% CI: 1.16-1.40, P<0.001) and CD4/CD8 ( OR=0.39, 95% CI: 0.15-0.99, P=0.048) were independent factors for predicting 131I treatment response. The cut-off values of psTg and CD4/CD8 for predicting non-ER were 6.78 μg/L and 1.67, respectively. Conclusions:Cellular immune status before initial 131I treatment may predict treatment response in young and middle-aged patients with PTC. It indicates non-ER response when Tg is higher than 6.78 μg/L and CD4/CD8 is lower than 1.67.

The grading of evidence is an important factor in clinical decision-making. The current evidence grading system based on western medicine is limited in the clinical practice of traditional Chinese medicine （TCM）， therefore we propose the solutions to the development of grading system for TCM interventional evidence， following the international evidence grading standards， taking into considerations of the unique characteristics of TCM practice， based on the Grades of recommendation， assessment， development and evaluation （GARDE） evaluation system， and integrating with grading system regarding TCM classical literature and empirical evidence from modern famous doctors. The evidence from classical literature is suggested to be evaluated from three aspects including source of ancient medical records， comprehensive of treatment details， and the inheritance. The qualification of famous doctors， content integrity， and inheritance of experiences will be used to evaluate the evidence from famous doctors' experience. The multi-sourced evidence such as TCM classical literature， experience of modern famous doctors， and modern researches is mainly integrated in a qualitative way， and the overall level of evidence of TCM interventions will be graded consistently with the GRADE system based on modern research. The evidence from classical literature and modern famous doctors' experience will be assessed and considered as supplementary evidence， which will make the evaluation of clinical evidence more objectively and comprehensively， thereby guiding clinical practice further.
