Objective: To explore the associations of moderate to vigorous intensity physical activity (MVPA) and sedentary behavior (SB) among primary and secondary school students and their parents, so as to provide a scientific basis for formulating targeted physical activity promotion strategies for children and adolescents. Methods: From 2021 to 2022, basic information and 24 h movement behaviors of 2 484 pairs of students and their parents were collected from five primary and secondary schools in Haizhu District, Guangzhou City, with a convenient sampling combining with cluster sampling method. Component regression models were constructed to analyze the relationship between parental MVPA, SB and primary and secondary school students MVPA and SB, and a component isochronous substitution model was used to explore the effects of mutual substitution between parental MVPA, residual components (time use components other than SB during the 24 h period), and SB on the behavioral activities of MVPA and SB in primary and secondary school students. Results: Parental MVPA and SB of students in grade 1 to 3 were positively correlated with both students MVPA and SB ( β=0.06, 0.12, P <0.01). The component isochronous substitution model showed that substituting 10 and 20 minutes of MVPA for SB by parents in grade 1 to 3 was associated with an increase in MVPA of students, and substituting 10 and 20 minutes of residual ingredients for SB was associated with a decrease in SB of students, with mean changes of 0.8 (95% CI =0.4-1.2) and 1.4 (95% CI =0.7-2.2) and -1.4 (95% CI =-1.7 to -1.1) and -2.9 (95% CI =-3.4 to -2.3)( P <0.05). No statistically significant associations were observed between parents of students in grades 4 to 6 and 7 to 9 and students physical activity and sedentary behaviour ( P >0.05). Conclusions Parents of students in grades 1 to 3 increases MVPA and decrease SB are beneficial to increase MVPA and decrease SB of students. Parents could promote physical activity among primary and secondary school students, and the intervention gateway should be advanced, with the low grades as the optimal intervention period.

BackgroundSchizophrenia is a complex， chronic and severe mental disorder， and the pathogenesis of which has not been fully elucidated. The abnormalities in lipid metabolism and circulating metabolomes have already been implicated in the pathophysiology of schizophrenia. However， available studies have mainly focused on a few liposomes and circulating metabolites， failing to systematically reveal the mediating role of circulating metabolomes in the causal relationship between liposomes and schizophrenia. ObjectiveTo uncover mediating role of circulating metabolomes in the causal relationship between liposomes and schizophrenia， thereby providing biomarkers and potential therapeutic targets for the prevention and treatment of schizophrenia. MethodsData from Genome-Wide Association Studies （GWAS） were analyzed， taking data on 179 liposomes as exposure variables， data on 123 circulating metabolites as intermediate variables， and data on schizophrenia as outcome variable. A two-step， two-sample Mendelian randomization analysis was conducted using the inverse-variance weighted （IVW）， MR- Egger， Weighted median， and Weighted mode methods to study the causal relationship of liposomes with schizophrenia and the mediating role of circulating metabolomes in the relationship. ResultsIVW model identified 8 lipids associated with schizophrenia without reverse causality. There were 5 circulating metabolomes strongly associated with schizophrenia. Acetate played a significant mediating role in the causal relationship between phosphatidylinositol （18：0_18：2） and schizophrenia （P=0.023， 95% CI： 0.036~0.532）， accounting for 28.4% of the causal relationship. ConclusionThis study demonstrates a causal relationship between liposomes and schizophrenia， with phosphatidylinositol being a risk factor in the progression of schizophrenia， and acetate playing a mediating role in this process. ［Fund by National Natural Science Foundation of China General Program （number， 82271546）； Shanxi Merit Funding for Overseas Students Sci-Tech Activities Project （number， 20240041）； Shanxi Province Science and Technology Innovation Leading Talent Team Project （number， 202304051001049）； Shanxi Scientific Research Foundation for the Returned Overseas Chinese Scholars （number， 2022-190）； "Six Measures for Health Care Prosperity" Specialized Research Program （number， Y2024008）］

Objective For the development of the electronic patient-reported outcome measures(ePRO)for stroke,the scale′s equivalence,i.e,differential item functioning(DIF)was assessed,aiming to compare whether paper-and mobile-based collection methods affect the participants′responses.Methods The patient information was collected using the developed App,and the DIF was detected using the mean and covariance structure(MACS)model to analyse whether the scale maintained a good measurement equivalence after changing to mobile-based from paper-based.Results Items PHD7,PHD8,PHD14,PSD3,PSD9,SOD1,and SOD6 exhibited uniform DIF(P1＜α1),PHD9,PHD10,PHD11,PHD12,SOD5,and THD1 exhibited non-uniform DIF(P2＜α2),and SOD7 and THD2 exhibited both uniform and non-uniform DIF.The DIF between the different measurement modalities existed for the above 15 items;however,it was within the acceptable limit.Conclusion The mPRO patient follow-up system developed in this study by assessing the DIF between the scale′s different data collection methods confirmed that mobile-based data collection did not affect the participants′response,and the measurement method shift did not affect the scale measurement equivalence.The system yielded accurate and reliable measurements that can be used in clinical practice and optimized in its application course.

Objective:To elucidate the cytopathological characteristics,molecular subtypes,and clinical prognoses of metastatic breast car-cinoma with serosal effusions.Methods:Seventeen cases that included effusion cytology and clinical data were retrospectively analyzed.Two patients were diagnosed between April 2016 and September 2023 at the Suzhou Ninth Hospital Affiliated to Soochow University,and 15 patients were diagnosed at The First Affiliated Hospital of Soochow University.Cytopathological characteristics,molecular subtypes,and prognoses were analyzed.Results:The cytopathological features of metastatic breast carcinoma in serosal effusions were as follows:1)In-vasive ductal carcinoma:one cell type was relatively densely arranged in nests or colored spheres,which displayed an elevated nuclear/cyto-plasmic ratio,irregular nuclear membrane,and cytoplasmic mucin vacuoles.The other cell type was tiled,single scattered,and varied in size and shape,with enlarged nuclei and elevated nuclear/cytoplasmic ratio.2)Invasive lobular carcinoma:cells were scattered and uniform in size and shape.The nuclei had a relatively regular shape,but displayed an elevated nuclear-to-cytoplasmic ratio.Among the 17 breast can-cer cases,6 had transitioned in molecular subtyping,including 1 case from Luminal A to triple-negative type,1 case from Luminal B to hu-man epidermal growth factor receptor 2(HER-2)-overexpressing type,and 4 cases from Luminal B to triple-negative type.Conclusions:The cytopathological characteristics of serous effusion cells combined with immunocytochemical staining and fluorescence in situ hybridization(FISH)suggest that it is important to determine the origin and molecular typing of tumor cells.This provides an important basis for precise clinical treatment and prognosis.

Objective:To evaluate the relationship between prognostic nutritional index (PNI) and myocardial injury after non-cardiac surgery (MINS).Methods:This was a retrospective cohort study. The clinical data of adult patients ( n=2 203) who underwent liver resection surgery with general anesthesia at our center from January 2016 to August 2019 were retrospectively collected. The predictive value of preoperative PNI for MINS and the optimal cut-off value of PNI were evaluated and determined according to the receiver operating characteristic curve, and the patients were divided into 2 groups based on the cut-off value: high PNI group and low PNI group. Logistic regression analyses were applied to investigate the relationship between preoperative PNI and MINS. According to the same inclusion and exclusion criteria, the clinical data of patients at our center from January 2022 to December 2023 were collected as the validation set ( n=2 525), and they were grouped using the same PNI cutoff value. Logistic regression analyses were used to verify the relationship between PNI and MINS. Results:The receiver operating characteristic curve analysis showed that the area under the curve of preoperative PNI for predicting MINS was 0.651 (95% confidence interval [ CI] 0.602-0.699), with an optimal cut-off value of 46.193, and the specificity and sensitivity were 0.729 and 0.519 respectively. The integer 46 was considered as the optimal cutoff value for PNI, and the patients were divided into low PNI group (PNI<46, n=606) and high PNI group (PNI≥46, n=1 597). Both univariate and multivariate logistic regression analyses showed that preoperative low PNI was an independent risk factor for the occurrence of MINS (univariate: OR=2.873, 95% CI 2.063-4.003, P<0.001; multivariate: OR=1.844, 95% CI 1.241-2.600, P=0.003). The results in the validation set were still robust (univariate: OR=2.694, 95% CI 1.890-3.833, P<0.001; multivariate: OR=1.602, 95% CI 1.071-2.385, P=0.021). Conclusions:Preoperative low-level PNI is an independent risk factor for MINS, with a certain predictive value.

In various types of inspections and self-inspections, it was found that compliance and rationalization in diagnosis and charging were the more common problems in hospital, leading to refusal of medical insurance payment. In 2022, the failure mode and effect analysis was conducted in a Grade-A tertiary hospital in Jinhua to identify the high-risk points in the process of diagnosis and treatment and charging, and building six major information technology transformation scenarios and formulating specific transformation measures, to avoid or reduce the refusal of medical insurance payment in advance. Through the digital transformation of medical insurance supervision system, a whole process intelligent supervision has been implemented, including pre event review, mid event reminder and intelligent correction, and post event big data precise analysis. It promoted compliant diagnosis and treatment of medical personnel and accurate charging, which could provide reference for other medical institutions to use medical insurance funds reasonably.

Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.

BackgroundPsychological problems such as depression and anxiety are common in pregnant women， and many studies have found that body image disturbance is closely related to depression and anxiety symptoms. Still， there is large variability in previous findings. ObjectiveTo review the researches on the relation of body image disturbance to depression and anxiety in pregnant women， and to provide a reference for interventions targeting maternal body image disturbance and depression and anxiety symptoms. MethodsOn January 10， 2023， well qualified literature focusing on the relationship between body image disturbance and depression and anxiety symptoms in pregnant women were searched in PubMed， Embase， CINAHL， Web of Science， China National Knowledge Infrastructure （CNKI）， VIP databases， Wanfang Data Database and China Biology Medicine disc （CBMdisc） from inception to January 1， 2023. The research content， factors influencing body image disturbance and relevant findings were extracted and summarized for analysis. ResultsA total of 14 articles were included in this review. The body image disturbance in pregnant women was manifested predominantly by an excessive concern about body weight and shape， and was affected by demographic characteristics， sociocultural factors， obstetric factors and other factors. Furthermore， body image disturbance significantly predicted the occurrence of depression， and proved a close relationship with anxiety symptoms. ConclusionBody image disturbance seriously affects the physical functioning and psychological status of pregnant women and may further exacerbate the symptoms of depression and anxiety.

Objective:To investigate the clinical efficacy of thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point on lumbodorsal myofascial pain syndrome of cold-damp stagnation type.Methods:A total of 90 patients with lumbodorsal myofascial pain syndrome of cold-damp stagnation type admitted to Zhejiang Provincial Hospital of Integrated Traditional Chinese and Western Medicine from September 2021 to April 2022 were included in this study. They were randomly divided into three groups ( n = 30/group) using the random number table method. Patients in the Chinese herbal ointment group were treated by external application of Chinese herbal ointment at the trigger point. Patients in the thunder-fire moxibustion group were treated with thunder-fire moxibustion. Patients in the combined therapy group were treated with thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point. All patients were treated for 28 consecutive days. Clinical efficacy was compared among the three groups. Before and after treatment, the Visual Analogue Scale score, local tenderness score, Oswestry Disability Index score and Pittsburgh Sleep Quality Index score were compared among the three groups. Results:Total response rate (96.67%) in the combined therapy group was significantly higher than 73.33% in the thunder-fire moxibustion group and 66.67% in the Chinese herbal ointment group ( χ2 = 9.01, 4.70, both P < 0.05). Visual Analogue Scale score and local tenderness score in the combined therapy group were (1.96 ± 0.93) points and (1.00 ± 0.69) points, respectively, which were significantly lower than (2.43 ± 0.87) points and (1.37 ± 0.56) points in the thunder-fire moxibustion group and (2.77 ± 0.86) points and (1.50 ± 0.57) points in the Chinese herbal ointment group ( F = 6.22, 5.38, both P < 0.05). The Oswestry Disability Index score in the combined therapy group was (19.80 ± 3.80) points, which was significantly lower than (22.30 ± 2.82) points in the thunder-fire moxibustion group and (23.60 ± 3.71) points in the Chinese herbal ointment group ( F = 9.07, both P < 0.05). After treatment, the Pittsburgh Sleep Quality Index score in the combined therapy group was (5.30 ± 1.12) points, which was significantly lower than (6.50 ± 1.33) points in the thunder-fire moxibustion group and (6.73 ± 1.41) points in the Chinese herbal ointment group ( F = 10.59, both P < 0.05). Conclusion:Thunder-fire moxibustion combined with external application of Chinese herbal ointment at the trigger point is highly effective on lumbodorsal myofascial pain syndrome of cold-damp stagnation type than monotherapy. The combined therapy can markedly reduce pain and greatly improve lumbodorsal function and sleep quality.

Objective:To compare the clinical characteristics and prognosis of bacterial liver abscess in patients with or without diabetes mellitus (DM), to provide a reference for clinical diagnosis and treatment.Methods:Patients with bacterial liver abscesses hospitalized in Tongren Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to August 2021 were enrolled, and their clinical data were collected. The patients were divided into diabetic and non-diabetic groups for comparison according to whether they had comorbid DM. Statistical analysis was performed by chi-square test or Fisher′s exact test, and multivariate logistic regression analysis.Results:A total of 131 patients with bacterial liver abscesses were included, including 47 cases in the diabetic group and 84 cases in the non-diabetic group. The percentages of platelet count <100×10 9/L, C-reactive protein>10 mg/L, and total bilirubin>17.5 μmol/L were lower in the diabetic group than that in the non-diabetic group, and the differences were all statistically significant ( χ2=3.90, 6.44 and 5.56, respectively, all P<0.05). The percentage of multiple abscesses in the diabetic group was 10.6%(5/47), which was lower than 29.8%(25/84) in the non-diabetic group, and the difference was statistically significant ( χ2=6.24, P=0.012). The positive rate of pus culture for Klebsiella pneumoniae was 64.9%(24/37) in the diabetic group, which was higher than 41.5%(27/65) in the non-diabetic group, with a statistically significant difference ( χ2=5.13, P=0.023). The incidences of pleural effusion and abscesses at other sites in the diabetic group were 29.8%(14/47) and 10.6%(5/47), respectively, which were both higher than 14.3%(12/84) and 1.2%(1/84) in the non-diabetic group, respectively, and the differences were statistically significant ( χ2=4.55, Fisher′s exact test, both P<0.05). The proportion of hospital stays>21 d was 34.0%(16/47) in the diabetic group, which was higher than 16.7%(14/84) in the non-diabetic group, with a statistically significant difference ( χ2=5.15, P=0.023). DM (odds ratio ( OR)=2.654, 95% confidence interval ( CI) 1.020 to 6.907, P=0.046) and abscess maximum diameter>10 cm ( OR=11.045, 95% CI 4.493 to 27.154, P<0.001) were significant risk factors for hospital stay>21 d. Conclusions:Bacterial liver abscesses combined with DM are more common with single abscess, a higher rate of Klebsiella pneumoniae infection, and more likely to develop pleural effusions and abscesses at other sites. Liver abscesses>10 cm in maximum diameter and comorbid DM would prolong hospital stay.
