OBJECTIVES: To evaluate the value of ⁶⁸Ga-DOTATATE and ¹⁸F-FDG PET/CT imaging in staging and treatment decision for gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN). METHODS: This retrospective analysis was conducted in 49 patients with GEP-NEN undergoing ¹⁸F-FDG and ⁶⁸Ga-DOTATATE PET/CT imaging at our hospital from August, 2020 to March, 2023, including 34 newly diagnosed patients and 15 patients with recurrence or metastasis after treatment. GEP-NEN were classified into G1, G2, and G3 neuroendocrine tumors (NET) and neuroendocrine carcinomas (NEC) based on pathological typing. The detection efficiency were classified into 4 patterns based on the number of positive tumor lesions detected by the two tracers: ⁶⁸Ga-DOTATATE>¹⁸F-FDG (A); ⁶⁸Ga-DOTATATE=¹⁸F-FDG (B); ⁶⁸Ga-DOTATATE<¹⁸F-FDG (C); and complementation (D). The value of dual-modality imaging in staging and treatment decision were evaluated by visual analysis. RESULTS: In the 49 patients with GEP-NEN, ⁶⁸Ga-DOTATATE PET/CT was superior to ¹⁸F-FDG PET/CT for detecting systemic tumor lesions (P<0.001) and more sensitive for detecting primary/recurrent lesions, lymph node metastasis, liver metastasis, and bone metastasis (P<0.05), while ¹⁸F-FDG PET/CT had higher detection rates for lung metastasis and peritoneal metastasis (P<0.05). In terms of the detection efficiency, Pattern A was found in 46.9% (23/49) patients, Pattern B in 38.8% (19/49), Pattern C in 12.2% (6/49), and Pattern D in 2.0% (1/49). The complementary value of ¹⁸F-FDG PET/CT to ⁶⁸Ga-DOTATATE PET/CT was 0% in G1 NET patients (0/13), 8.3% in G2 NET patients (2/24), 50% in G3 NET patients (3/6), and 33.3% in NEC patients (2/6). 12.2% (6/49) of the patients had their staging confirmed or changed due to additional lesions detected by ¹⁸F-FDG PET/CT imaging, resulting subsequently in establishment or adjustment of their treatment plans. CONCLUSIONS ⁶⁸Ga-DOTATATE PET/CT imaging should be the primary choice for GEP-NEN patients. Additional ¹⁸F-FDG PET/CT imaging can potentially improve precision of staging and treatment decision-making for G2, G3 and NEC patients but provides virtually no clinical benefits for G1 NET patients.

Background Mobile phone addiction has attracted widespread attention in society,and psychological abuse and neglect is an important factor in predicting mobile phone addiction,whereas limited research has been done to evaluate its impact on mobile phone addiction.Objective To explore the correlation of psychological abuse and neglect with mobile phone addiction,and to test the pathway of self-esteem and interpersonal alienation,so as to provide references for preventing and curbing mobile phone addiction in junior high school students.Methods In May 2022,a cluster sampling was utilized to select 800 students in two middle schools in a county of Hainan Province,and all students were assessed using Child Psychological Abuse and Neglect Scale(CPANS),Mobile Phone Addiction Index(MPAI),Rosenberg Self-esteem Scale(SES)and Interpersonal Alienation Scale of Adolescent StudentsAlienation Scale.Pearson correlation analysis was adopted to determine the correlation among the above-mentioned scales,and Process Macro 3.5 for SPSS was used to test the mediation effect.Results CPANS score was negatively correlated with SES score(r=-0.278,P<0.01),and positively correlated with Interpersonal Alienation Scale score and MPAI score(r=0.471,0.372,P<0.01).SES score was negatively correlated with Interpersonal Alienation Scale score and MPAI score(r=-0.438,-0.196,P<0.01).Interpersonal Alienation Scale score was positively correlated with MPAI score(r=0.392,P<0.01).Interpersonal alienation(indirect effect value was 0.104)played a mediation role in the relationship between psychological abuse and neglect and mobile phone addiction.Self-esteem and interpersonal alienation exhibited a chained mediation effect on the relationship between psychological abuse and neglect and mobile phone addiction(indirect effect value was 0.026),accounting for 6.99%of the total effect.Conclusion Psychological abuse and neglect can not only directly predict mobile phone addiction,but also can indirectly affect mobile phone addiction through separate mediation of interpersonal alienation or chained mediation of self-esteem and interpersonal alienation.

Objective To study the changes in serum immunoglobulin levels in children with thalassemia who undergo repeated blood transfusions and explore their correlation with delayed hemolytic transfusion reactions(DHTR).Methods Serum samples from children with thalassemia who received blood transfusion treatment from June 2022 to April 2023(ob-servation group)and healthy children who underwent physical examination(control group)in our hospital were collected.The levels of serum immunoglobulins(IgG subtype,IgM,IgA,IgE and IgD)were detected using flow cytometry CBA multi-factor quantitative detection technology,and the differences between the two groups were compared.The children were divided into 4 groups according to different transfusion numbers:≤10 numbers,11-30 numbers,31-50 numbers and＞50 numbers,and the differences between different blood transfusion numbers and serum immunoglobulin levels in each group were compared using one-way analysis of variance(ANOVA).Children with thalassemia with DHTR were in the hemolysis group,and children with thalassemia who did not experience DHTR were in the non-hemolysis group.The changes in serum immunoglobulins(IgG subtypes,IgM,IgA,IgE and IgD)between the two groups were compared to explore the correlation between serum immunoglobulins in thalassemia children with repeated transfusion and DHTR.Results The levels of IgG1,IgG3,IgG4 and IgA in the observation group were significantly higher than those in the control group,with the increase of(2.07±2.12),(0.67±2.03),(0.30±0.37)and(6.04±11.40)mg/mL,respectively,while the level of IgD in observation group was significantly lower than that in the control group,with a decrease of(0.03±0.01)mg/mL,P＜0.05.No significant difference was noticed in IgG2,IgM and IgE between the groups(P＞0.05).IgG1 and IgG4 both significantly increased with the number of blood transfusions.The IgG1 in the 4 groups increased sequentially as(0.30±0.62),(0.41±0.51)and(3.60±3.48)mg/mL,and IgG4 increased sequentially as(0.12±0.13),(0.22±0.07)and(0.21±0.38)mg/mL.IgG2,IgM and IgD showed a significant decrease,with IgG 2,IgM,and IgD in four groups decreased as(0.91±1.50),(0.14±0.10)and(0.05±0.05)mg/mL,respectively,showing significant differences with the number of blood transfusions(P＜0.05).No sig-nificant difference was found in IgG3,IgA and IgE with different number of transfusions(P＞0.05).IgG1,IgG3 and IgG4 in the hemolysis group were significantly higher than those in the non-hemolysis group,with an increase of(4.44±3.41),(0.73±1.26)and(0.52±0.40),respectively(P＜0.05).IgD in the hemolysis group was significantly lower than that in the non-hemolysis group,with a decrease of(0.00±0.06)mg/mL,P＜0.05.No significance was noticed in IgG2,IgM,IgA and IgE between the hemolysis group and the non-hemolysis group(P＞0.05).Conclusion The serum immunoglobulin levels of children with thalassemia who undergo repeated blood transfusions are abnormal.There are differences in correlation between the number of blood transfusions and serum immunoglobulin levels among children with thalassemia who undergo repeated blood transfusions.The relevant serum immunoglobulins for DHTR in children with thalassemia who undergo repeated blood transfusions are IgG1,IgG3 and IgG4.

Objective To assess the level of self-compassion in patients with lung cancer undergoing chemotherapy and identify its influencing factors in order to provide targeted intervention strategies for clinical nursing practice.Methods Using a convenience sampling method,a total of 110 patients with lung cancer who were hospitalized for chemotherapy in Fujian Cancer Hospital from January 2022 to December 2023 were selected.A general information questionnaire,self-compassion scale,M.D.Anderson symptom inventory-lung cancer,and perceived social support scale were used to investigate.Results The total score for self-compassion among lung cancer chemotherapy patients was(76.81±9.49)points,the total score for symptom burden was(112.05±35.98)points,and the total score for social support was(38.98±2.49)points.Self-compassion was negatively correlated with symptom burden(r=-0.849,P＜0.001)and positively correlated with social support(r=0.881,P＜0.001).Multiple linear regression analysis showed that age,gender,symptom burden and social support were the influencing factors of self-compassion in patients with lung cancer chemotherapy(P＜0.05).Conclusion The level of self-compassion among lung cancer chemotherapy patients is moderately low.Age,gender,symptom burden and social support were the factors influencing self-compassion of patients with lung cancer chemotherapy.Nursing staff should consider demographic characteristics and use strategies such as reducing symptom burden and improving social support to enhance self-compassion levels,thereby reducing negative emotions and improving the quality of life.

Objectives:To explore the cardiac magnetic resonance(CMR)features of early ventricular aneurysm formation in patients with acute anterior myocardial infarction. Methods:One hundred and eight patients with acute anterior myocardial infarction who underwent primary percutaneous coronary intervention and completed CMR scans within two weeks were retrospectively analyzed and divided into non-ventricular aneurysm group(n=72)and ventricular aneurysm group(n=36)according to the absence or presence of early ventricular aneurysm after primary percutaneous coronary intervention.The obtained CMR images were imported into CVI42 software for image analysis,and a logistic regression analysis model was established to evaluate CMR features useful for the diagnosis of early ventricular aneurysm formation. Results:Aging and larger area of late gadolinium enhancement(LGE)and worse left ventricular systolic function and lower myocardial strain were features of patients in the ventricular aneurysm group as compared to the non-ventricular aneurysm group.LGE area(OR=1.32,95%CI:1.071-1.628,P=0.009),apical angle(OR=1.24,95%CI:1.041-1.475,P=0.016),septal mitral annular plane systolic excursion(septal MAPSE,OR=0.36,95%CI:0.169-0.757,P=0.007)and global longitudinal strain(GLS,OR=0.53,95%CI:0.154-0.953,P=0.046)were associated with early ventricular aneurysm formation.ROC curves were analyzed for the above four CMR parameters,and the AUC were 0.922,0.921,0.905,and 0.814,respectively.The optimal cutoff values were 28.5%,90°,8.245 mm,and 10.155%,respectively. Conclusions:Estimation of LGE area,apical angle,septal MAPSE and GLS using CMR technique can help diagnose early ventricular aneurysm in patients with acute anterior myocardial infarction.

Objective:To explore relationships between problematic mobile phone use and interpersonal distress, depression and sleep quality using a combined variable- and person-centered approach.Methods:From December 2021 to January 2022, a total of 851 middle school students were measured by the mobile phone addiction index scale, the college students interpersonal comprehensive diagnostic scale, the center for epidemiologic studies depression scale, and the Chinese version of Pittsburg sleep quality index. Common method bias test, descriptive statistics, and correlation analysis were performed using SPSS 26.0 statistical software, and Mplus 8.8 software was used to construct structural equation models for latent profile analysis.Results:The score of problematic mobile phone use was(47.23±14.50), the score of interpersonal distress was(8.72±5.68), the score of depression was(14.80±10.28), the score of sleep quality was(5.51±2.78). Variable-centered analysis revealed that problematic mobile phone use had a significant direct effect on sleep quality (effect value=0.22, 95% CI=0.11-0.34), accounting for 40.74% of the total effect. The mediating effect of depression was found between problematic mobile phone use and sleep quality (effect value=0.08, 95% CI=0.03-0.14), accounting for 14.81% of the total effect. Interpersonal distress and depression had a chain mediating effect between problematic mobile phone use and sleep quality(effect value=0.22, 95% CI=0.16-0.30), accounting for 40.74%(0.22/0.54) of the total effect. Person-centered analysis revealed that problematic mobile phone use was divided into three potential profiles: mild use group(26.1%), moderate use group(54.7%) and severe use group(19.2%). Depression(moderate use group: effect size=0.05, 95% CI=0.02-0.10; severe use group: effect size=0.07, 95% CI=0.02-0.12) and interpersonal distress-depression(moderate use group: effect size=0.13, 95% CI=0.09-0.18; severe use group: effect size=0.21, 95% CI=0.15-0.28) had a significant relative mediating effect between problematic mobile phone use profiles and sleep quality. Conclusion:Adolescent problematic mobile phone use is heterogeneous, with both variable-centered and person-centered results indicating that depression and interpersonal distress-depression mediated the effects of adolescent problematic mobile phone use on sleep quality.

Objective To analyze the etiological characteristics and the variation of pathogens spectrum in hospitalized children with a-cute respiratory tract infection(ARTI)before and after COVID-19 under"the level B of management for class B"of infectious diseases(Level B for Class B)in Shenzhen,in order to provide reference for the clinical diagnosis,treatment and prevention of ARTI.Meth-ods The ARTI cases from January 8,2022 to July 30,2022 were selected as before"Level B for Class B",and the cases from Janu-ary 8,2023 to July 30,2023 were selected as after"Level B for Class B".The pharyngeal swab samples submitted for analyzing 11 common pathogens,such as COVID-19,influenza virus(Ⅳ),respiratory syncytial virus(RSV)and mycoplasma pneumoniae(MP)in the children with ARTI admitted to Shenzhen Children's Hospital.Results SARS-CoV-2 were detected as positive in 347 cases,a-mong which 225 cases were before"Level B for Class B"including 29 cases combined with other pathogens(12.89％,29/225)and human parainfluenza viruses(HPIV)was the most common(31.03％,9/29).After"Level B for Class B",SARS-CoV-2 were detec-ted as positive in 122 cases,including 28 cases combined with other pathogens(22.95％,28/122),and RSV was the most common(28.57％,8/28).There was a statistical difference between the positive rate of SARS-CoV-2 combined with other pathogens before and after"Level B for Class B"(X2=5.834,P=0.016).After"Level B for Class B",the total pathogen detection rate(positive for at least one pathogen)was 60.82％(2 864/4 709)in the spring(January 8,2023 to April 30,2023),and influenza virus A(IVA)(22.64％,1 066/4 709),rhinovirus(HRV)(19.86％,935/4 709)and RSV(13.29％,626/4 709)were the main pathogens,and there were 301 cases(6.39％,301/4 709)of mixed infections.In the summer(May 1,2023 to July 30,2023),the total detection rate of pathogens was 70.26％(4 012/5 710),among which RSV(21.63％,1 235/5 710),MP(13.91％,794/5 710),HPIV(10.05％,574/5 710)were the main pathogens,and there were 710 cases(12.43％,710/5 710)of mixed infections,all of which were significantly higher than the same period before"Level B for Class B".The difference was statistically significant(P＜0.05).Conclusion After"Level B for Class B"for COVID-19,the detection rate of 11 common pathogens increased significantly and the pathogen spectrum of ARTI changed significantly.

【Objective】 To investigate the changes in cellular immunity (peripheral blood lymphocyte subsets) and humoral immunity (serum immunoglobulin and ferritin) status among children with thalassemia who received repeated transfusions in Yunnan. 【Methods】 Forty-six children with thalassemia who underwent repeated blood transfusions from January 2020 to October 2022 were selected as the observation group. Forty children with thalassemia who did not receive blood transfusion were included in control group 1, and 46 healthy children underwent physical examination were included in control group 2. The differences in lymphocyte subsets, serum immunoglobulin levels and ferritin concentrations were compared among the three groups. 【Results】 For lymphocyte subsets: CD3⁺, CD4⁺ and CD4⁺/CD8⁺ in the observation group was lower than the control group 1 and 2: 57.60±8.36 vs 64.57±7.56 vs 66.58±5.65, 33.16±5.67 vs 38.62±8.36 vs 38.62±6.41 and 1.49±0.09 vs 2.32±0.15 vs 2.13±0.16, respectively; CD16⁺ CD56⁺ in the observation group was lower than the control group 2: 11.21±5.06 vs 16.70±7.92; CD8⁺ in the observation group was higher than control group 1 and control group 2: 26.63± 1.75 vs 20.60±1.43 vs 18.92±0.84; CD19⁺ in the observation group was higher than the control group 2: 24.06±6.42 vs 19.67 ±8.42, P<0.05, but no significant difference was noticed between the two control groups(P>0.05). For serum immunoglobulin and ferritin: IgG and ferritin in the observation group were higher than control group 1 and control group 2: 10.59±3.88 vs 7.02±3.88 vs 5.58±1.98 and 2 037.37±1 377.59 vs 72.63±56.71 vs 59.48±33.88. IgA in the observation group was higher than the control group 2: 1.06±0.92 vs 0.39±0.32(P<0.05), but no significant difference was noticed between the two control groups (P>0.05). The difference of IgM and IgE between the three groups was not significant (P > 0. 05). 【Conclusion】 The proportion of lymphocyte subsets in thalassemia children with repeated blood transfusion was imbalanced,and the level of immunoglobulin in humoral immunity was abnormal.

【Objective】 To share the experience of autologous platelet-rich plasma(PRP) combined therapy in successful treatment of refractory osteomyelitis with fractures in children. 【Methods】 One case of refractory osteomyelitis with fracture in children failed to respond to traditional treatment for more than 14 months. A total of 20 mL of whole blood was collected from the child, and 6 mL of PRP with 4 to 5 times concentration was prepared by secondary centrifugation. To prepare 2 cm×2 cm platelet concentrate gel (PG), 3 mL of PRP was mixed with a 0.3 mL activator which was then covered with an absorbable dressing. A three-way tube sprayed the remaining 3 mL of PRP and 0.3 mL activator into the surrounding tissues. 【Results】 The X-ray film of the patient followed up for 1 week showed that the fracture line was blurred, and the fracture end had obvious callus formation. The X-ray film reexamination at 4 months showed that the fracture end healed well, the fracture surface healed, and the osteomyelitis healed. 【Conclusion】 Autologous PRP has a good effect in the treatment of refractory osteomyelitis combined with fracture in children, which can provide a new method for clinical treatment.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.
