Objective: To explore the mediating role of psychological and physical aggression in the association between maternal emotional symptoms with emotional and behavioral problems in preschool children, so as to provide references for effective intervention of risk factors related to childrens emotional and behavioral problems. Methods: A longitudinal study was conducted to select 12 kindergarten children and their mothers in Wuhu City, Anhui Province by using stratified clustering sampling. The baseline survey was carried out in June 2021, followed up every six months, and a total of 3 followups were administered. Totally 853 valid questionnaires of junior class children were included by the survey data from baseline, second and thirl followups. The Depression Anxiety and Stress Scale-21 (DASS-21), the Parent-Child Conflict Tactics Scales (CTSPC) and the Strength and Difficulties Questionnaire (SDQ) were used to measure maternal emotional symptoms, psychological and physical aggression, and childrens emotional and behavioral problems, respectively. Results: The physical aggression of mothers towards children in boys was higher than in girls (t=3.53, P<0.05). The results of correlation analysis showed that maternal depressive symptoms were positively correlated with psychological aggression, physical aggression and childrens SDQ scores (r=0.20, 0.21, 0.18, P<0.01), maternal anxiety symptoms were positively correlated with psychological aggression, physical aggression and childrens SDQ scores (r=0.24, 0.22, 0.10, P<0.01), respectively; maternal stress symptoms were positively correlated with psychological aggression, physical aggression. The SDQ scores were positively correlated (r=0.26, 0.25, 0.18, P<0.01), and the scores of maternal psychological aggression and physical aggression were positively correlated with the SDQ scores of children (r=0.12, 0.16, P<0.01). The mediating analysis showed that after controlling for related confounding factors, psychological aggression played a partial mediating effect in the association between maternal depressive symptoms and childrens emotional and behavioral problems, and the mediating effect ratio was 8.05%. Physical aggression played a partial mediating effect in the association between maternal depression, anxiety and stress symptoms and childrens emotional and behavioral problems, which were 15.94%, 11.73% and 12.54% (P<0.05), respectively. Conclusions Psychological and physical aggression play mediating roles in the association between maternal emotional symptoms and childrens emotional and behavioral problems, and actively improving maternal emotional symptoms and their childrens discipline methods can help reduce the occurrence of emotional and behavioral problems in preschool children.

OBJECTIVE: To analyze the clinical characteristics of patients with emergency in-hospital cardiac arrest (IHCA) in Kashgar, Xinjiang Uygur Autonomous Region and the factors affecting the success rate of cardiopulmonary resuscitation. METHODS: Retrospectively selected patients who had cardiac arrest and cardiopulmonary resuscitation in the emergency department of the People's Hospital of 6 counties and cities in Kashgar area from January 2019 to January 2022. The clinical data of all patients were collected, including gender, age, major underlying diseases, the beginning and duration of resuscitation, the number of electric defibrillation acute physiology and chronic health evaluation II (APACHE II). According to whether the resuscitation was successful, all patients were divided into successful resuscitation group and failed resuscitation group. The clinical characteristics of the two groups were compared. Then, the influencing factors of the success rate of cardiopulmonary resuscitation in IHCA patients were analyzed by binary Logistic regression. RESULTS: A total of 1 376 patients were enrolled, including 1 117 cases of failed resuscitation and 259 cases of successful resuscitation. The success rate of resuscitation was 18.82%. Compared with the resuscitation failure group, the patients in the successful resuscitation group were younger (age: 49.10±20.99 vs. 58.44±18.32), the resuscitation start time was earlier [resuscitation start time ≤ 5 minutes: 76.45% (198/259) vs. 66.61% (744/1 117)], the proportion of cardiovascular and cerebrovascular diseases was lower [cardiovascular disease: 49.42% (128/259) vs. 58.19% (650/1 117), cerebrovascular disease: 17.37% (45/259) vs. 21.58% (241/1 117)], the number of electric defibrillation was lower [times: 0 (0, 2) vs. 1 (0, 1)], the proportion of endotracheal intubation was more [80.31% (208/259) vs. 55.60% (621/1 117)], APACHE II score was lower (13.75±8.03 vs. 17.90±4.63), and the difference was statistically significant (all P < 0.01). Binary Logistic regression analysis showed that age, start time of resuscitation, ventilation mode and APACHE II score were protective factors affecting the success rate of cardiopulmonary resuscitation in patients with emergency IHCA [age: odds ratio (OR) = 0.982, 95% confidence interval (95%CI) was 0.973-0.991, P < 0.001; resuscitation start time ≤ 5 minutes: OR = 0.629, 95%CI was 0.409-0.966, P = 0.034; tracheal intubation assisted ventilation: OR = 0.243, 95%CI was 0.149-0.397, P < 0.001; low APACHE II score: OR = 0.871, 95%CI was 0.836-0.907, P < 0.001], while underlying diseases (cardiovascular diseases) are a risk factor affecting the success rate of cardiopulmonary resuscitation (OR = 1.190, 95%CI was 1.015-1.395, P = 0.036). CONCLUSIONS Age, resuscitation start time, ventilation mode, APACHE II score and major underlying diseases (cardiovascular diseases) have a greater impact on the success rate of resuscitation in IHCA patients. The above factors are conducive to improving or formulating more effective rescue strategies for IHCA patients, so as to achieve the purpose of improving the success rate of clinical treatment.

Background: /Aim: The Barcelona Clinic Liver Cancer (BCLC) guidelines recommend systemic therapy as the only first-line treatment for patients with BCLC stage C hepatocellular carcinoma (HCC) despite its heterogeneity of disease extent. We aimed to identify patients who might benefit from combined transarterial chemoembolization (TACE) and radiation therapy (RT) by subclassifying BCLC stage C. Methods: A total of 1,419 treatment-naïve BCLC stage C patients with macrovascular invasion (MVI) who were treated with combined TACE and RT (n=1,115) or systemic treatment (n=304) were analyzed. The primary outcome was overall survival (OS). Factors associated with OS were identified and assigned points by the Cox model. The patients were subclassified into three groups based on these points. Results: The mean age was 55.4 years, and 87.8% were male. The median OS was 8.3 months. Multivariate analysis revealed a significant association of Child-Pugh B, infiltrative-type tumor or tumor size ≥10 cm, main or bilateral portal vein invasion, and extrahepatic metastasis with poor OS. The sub-classification was categorized into low (point ≤1), intermediate (point=2), and high (point ≥3) risks based on the sum of points (range, 0–4). The OS in the low, intermediate, and high-risk groups was 22.6, 8.2, and 3.8 months, respectively. In the low and intermediate-risk groups, patients treated with combined TACE and RT exhibited significantly longer OS (24.2 and 9.5 months, respectively) than those who received systemic treatment (6.4 and 5.1 months, respectively; P<0.0001). Conclusions Combined TACE and RT may be considered as a first-line treatment option for HCC patients with MVI when classified into low- and intermediate-risk groups.

Background: /Aim: We aimed to investigate the efficacy and safety of stereotactic body radiation therapy (SBRT) in elderly patients with small hepatocellular carcinomas (HCC). Methods: Eighty-three patients (89 lesions) with HCC who underwent SBRT between January 2012 and December 2018 were reviewed in this retrospective observational study. The key inclusion criteria were as follows: 1) age ≥75 years, 2) contraindications for hepatic resection or percutaneous ablative therapies, 3) no macroscopic vascular invasion, and 4) no extrahepatic metastasis. Results: The patients were 75-90 years of age, and 49 (59.0%) of them were male. Most patients (94.0%) had an Eastern Cooperative Oncology Group performance status of 0 or 1. Seventy-four patients (89.2%) had Child-Pugh class A hepatic function before SBRT. The median tumor size was 1.6 cm (range, 0.7-3.5). The overall median follow-up period was 34.8 months (range, 7.3-99.3). The 5-year local tumor control rate was 90.1%. The 3-year and 5-year overall survival rate was 57.1% and 40.7%, respectively. Acute toxicity grade ≥3 was observed in three patients (3.6%) with elevated serum hepatic enzymes; however, no patient experienced a worsening of the Child-Pugh score to ≥2 after SBRT. None of the patients developed late toxicity (grade ≥3). Conclusions SBRT is a safe treatment option with a high local control rate in elderly patients with small HCC who are not eligible for other curative treatments.

【Objective】 To assess three severe acute respiratorysyndrome coronavirus 2 (SARS-CoV-2) enzyme linked immunosorbent assays (ELISA) and one pseudotype lentivirus-based neutralization test (ppNAT) in detecting the convalescent plasma antibody levles from COVID-19. 【Methods】 30 COVID-19 convalescent plasma samples were screened for antibodies against SARS-CoV-2 using three kinds of SARS-CoV-2 ELISA reagents and one ppNAT test in Shenzhen. The controls consisted of plasma samples from 32 healthy blood donors in February 2019. The diagnostic efficacy analysis of various SARS-CoV-2 ELISA reagents was performed using real-time fluorescent Polymerase Chain Reaction (RT-PCR). We also analyzed correlation between different immunological reagents and the age, gender, hospitalization, and severity of illness. 【Results】 The positive yielding rate of ppNAT and three kinds of IgG ELISA was higher than that of IgM ELISA. The positive yielding rates of three kinds of IgG ELISA were 100%(30/30), 93.33%(28/30), and 96.67%(29/30) respectively, while the yielding rates in control group were all 0. The positive yielding rate of three IgM ELISAs were 93.33%(28/30), 70%(21/30)and 46.67% (14/30). All the cases from negative control group were negative for IgG and IgM. Pearson correlation coefficient was calculated; there was a strong correlation between ELISA reagent 2 IgG and ELISA reagent 3 IgG (r=0.765, P<0.01). The correlation between ppNAT, ELISA reagent 3 IgG and the age of recovered patients was 0.422 and 0.385, respectively (P<0.05), while no significant correlation was found between the duration of hospitalization, severity of illness, gender and antibody signal/cutoff (S/CO) (P>0.05). 【Conclusion】 In the convalescent plasma with nucleic acid confirmed covid-19, the yielding rates of different IgM antibodies varied greatly. Antibody levels were influenced by age to some extent.

Background: Oral metastasis by hepatocellular carcinoma (OMHCC) is extremely rare, and the prognosis had been reported quite poor due to simultaneous multiple organ metastases. In this study, we report clinical features and survival of 10 new cases of OMHCC and suggest the criteria for palliative surgery. Methods: A retrospective clinical study including 10 new cases of oral OMHCC between 2006 and 2016 was performed. Clinical features and survival analysis were examined. The recorded variables were age, sex, site of oral metastases, size of oral tumor (largest diameter), and survival after oral histopathologic diagnosis. Results: There was male (n=8) predilection of OMHCC. The mean survival time was 16.9 months. Patient age ranged from 40 to 71 years (mean 56.5). Eight mandibular and two maxillary lesions were found. One patient showed simultaneously the maxilla and the oral tongue involvement. The most often encountered symptoms were swelling (80%) followed by pain (60%), numbness (60%), bleeding (10%), and tooth mobility (10%). Four patients underwent operation due to spontaneous bleeding and swelling of the cancer. Overall (from onset of hepatocellular carcinoma) and truncated survival (from onset of OMHCC) were 71.9 and 13.1 months respectively. Conclusion The prognosis of OMHCC was quite poor. Oral and jaw bone examination should be included in patients with multiple metastasis of HCC. Palliative surgery might be performed in patients who reported spontaneous bleeding, severe pain, and oral dysphasia due to tumor enlargement.

Purpose: To investigate the safety and efficacy of hypofractionated radiation therapy (HFRT) in patients with non-small cell lung cancer who are unfit for surgery or stereotactic body radiation therapy (SBRT) at our institution. Materials and Methods: From May 2007 to December 2018, HFRT was used to treat 68 lesions in 64 patients who were unsuitable for SBRT because of central tumor location, large tumor size, or contiguity with the chest wall. The HFRT schedule included a dose of 50–70 Gy delivered in 10 fractions over 2 weeks. The primary outcome was freedom from local progression (FFLP), and the secondary endpoints included overall survival (OS), disease-free survival, and toxicities. Results: The median follow-up period was 25.5 months (range, 5.3 to 119.9 months). The FFLP rates were 79.8% and 67.8% at 1 and 2 years, respectively. The OS rates were 82.8% and 64.1% at 1 and 2 years, respectively. A larger planning target volume was associated with lower FFLP (p = 0.023). Dose escalation was not associated with FFLP (p = 0.964). Four patients (6.3%) experienced grade 3–5 pulmonary toxicities. Tumor location, central or peripheral, was not associated with either grade 3 or higher toxicity. Conclusion HFRT with 50–70 Gy in 10 fractions demonstrated acceptable toxicity; however, the local control rate can be improved compared with the results of SBRT. More studies are required in patients who are unfit for SBRT to investigate the optimal fractionation scheme.

Objective: The diagnostic accuracy of novice residents in evaluating the scrotal pathology by point-of-care (POC) ultrasonography(US) was compared with that by the conventional US to determine the level of experience required toachieve competency. Methods: Three novice residents underwent a one-day training course on identifying scrotal pathologies using POC US.They performed POC US on patients with an acute scrotum to identify five pathological findings. The diagnosis was confirmedby conventional scrotal US. The sensitivity and specificity of POC US by novice residents were calculated, and thechanges in sensitivity and specificity over time were observed. Results: Sixty-two patients were included; the overall sensitivity and specificity were 76.7% (95% confidence interval [CI],61.3%-88.2%) and 78.9% (95% CI, 54.4%-93.9%), respectively. Decreased blood flow in the testicle showed very goodspecificity (100%; 95% CI, 93.8%-100.0%). The sensitivity and accuracy were variable at first 18 scans of each resident,but increased after 18 scans and were maintained over time. Conclusion Although the diagnostic accuracy of novice residents in evaluating the scrotal pathology using POC US wasvariable at first, the accuracy improved over time, especially after 18 scans of each resident. Nevertheless, larger, longtermresearch is needed to confirm the results of this study.

Background/Aims: Stereotactic body radiation therapy (SBRT) is used as an alternative ablative treatment in patients with hepatocellular carcinoma (HCC) not suitable for curative treatments. The purpose of this prospective study was to evaluate the long-term efficacy of SBRT for small (≤5 cm) HCCs. Methods: A phase II, single-arm clinical trial on SBRT for small HCCs was conducted at an academic tertiary care center. The planned SBRT dose was 45 Gy with a fraction size of 15-Gy over 3 consecutive days. The primary endpoint was 2-year local control rate. Radiologic responses were assessed according to the Response Evaluation Criteria in Solid Tumors (RECIST, version 1.1) and the modified RECIST criteria. Results: Between 2013 and 2016, 50 patients (53 lesions) were enrolled, with a median follow-up period of 47.8 months (range, 2.9–70.6). Patients’ age ranged from 41 to 74 years, and 80% were male. Median tumor size was 1.3 cm (range, 0.7–3.1). The 2- and 5-year local control rates were 100% and 97.1%, respectively. The 5-year overall survival rate was 77.6%. Six months after SBRT, radiologic responses were evident in 44 lesions (83%) according to the RECIST criteria and 49 (92.4%) according to the modified RECIST criteria. None of the patients showed grade ≥3 adverse events. Conclusions SBRT showed excellent results as an ablative treatment for patients with small HCCs while showing minimal toxicities. SBRT can be a good alternative for both curative and salvage intents in patients with HCCs that are unsuitable for curative treatments.
