ABSTRACT
To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi'an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi 'an Children's Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

@#Abstract: Objective To explore the influencing factors of serum HBeAg loss in patients with chronic hepatitis B (CHB) and and provide evidence for effective treatment of CHB. Methods A follow-up cohort of HBeAg-positive CHB patients was established in the the Infectious Diseases Outpatient Clinic of hospital. Regular follow-up and laboratory test indicators were collected to analyze the changes of serum HBeAg in HBeAg-positive CHB patients during the follow-up period. The subjects were divided into the case group (serum HBeAg loss) and the control group (serum HBeAg not loss) according to whether serum HBeAg loss occurred. The baseline data characteristics of the two groups were analyzed and compared, and the influencing factors of serum HBeAg loss were analyzed by Cox univariate and multivariate regression. Results A total of 634 HBeAg-positive CHB patients were enrolled, with a total follow-up of 2 570.01 person-years. Among them, 237 cases of serum HBeAg loss occurred, with the mean follow-up time of 40.92 months, and the rate of HBeAg loss was 9.22/100 person-years. There were significant differences in HBV family history, antiviral therapy, baseline WBC, PLT, ALT, AST, T˗Bil, GGT, AFP, quantitative HBsAg and quantitative HBeAg between serum HBeAg loss group and serum HBeAg not loss group (P<0.05). Cox regression analysis showed that family history of HBV (HR 0.68, 95%CI:0.50-0.92, P=0.012), ALT (HR2.06, 95%CI:1.52-2.79, P<0.001), quantitative HBsAg (HR 0.68, 95%CI:0.48-0.95, P=0.024), quantitative HBeAg (HR 0.48, 95%CI:0.31-0.74, P=0.001) were independent influencing factors for HBeAg loss in HBeAg-positive CHB patients. Conclusions HBeAg-positive CHB patients without family history of HBV, initial ALT≥80 U/L, quantitative HBsAg<1 000 IU/ml, quantitative HBeAg<1 000 C.O.I are more likely to have serum HBeAg loss.
ABSTRACT
Objective @#To evaluate the effectiveness of interventions for human papillomavirus ( HPV ) vaccine hesitancy among female university students based on the precaution adoption process model (PAPM), so as to provide the evidence for improving the coverage of HPV vaccine in this population. @*Methods @#HPV vaccine hesitant female students were selected using a cluster sampling method from Zhejiang Chinese Medical University, and randomly assigned to the PAPM group and control group. Students in the PAPM group received PAPM-based interventions for HPV vaccine hesitancy, while students in the control group were given routine interventions. The HPV-related knowledge, HPV vaccine-related knowledge and HPV vaccine hesitancy scores were collected from both groups prior to interventions ( T0 ), 0 ( T1 ), 1 ( T2 ) and 3 months post-interventions ( T3 ), and the effectiveness of interventions was evaluated using analysis of variance for repeated measures.@*Results @#There were 147 students in the PAPM group and 141 students in the control group. In the PAPM group, 36.73% of the students majored in medical sciences, and 48.23% were freshmen; in the control group, 39.72% majored in medical sciences, and 50.35% were freshmen. The mean scores of HPV- and HPV vaccine-related knowledge were significantly greater in the PAPM group than in the control group, respectively ( T1, 5.29 vs. 4.91; T2, 4.27 vs. 4.22; T3, 4.22 vs. 4.04; P<0.05 ); however, no significant differences were detected in the HPV vaccine hesitancy scores between the two groups, respectively ( T1, 2.98 vs. 2.95; T2, 3.07 vs. 3.07; T3, 3.08 vs. 2.97; P>0.05 ). The mean scores of the confidence dimension ( T1, 3.37 vs. 3.23; T2, 3.48 vs. 3.40; T3, 3.38 vs. 3.25 ) and the dimension of influence by others ( T1, 3.44 vs. 3.33; T2, 3.42 vs. 3.37; T3, 3.46 vs. 3.27 ) were significantly greater in the PAPM group than in the control group (P<0.05), while the mean scores of the complacency dimension were significantly lower in the PAPM group than in the control group ( T1, 1.98 vs. 2.03; T2, 2.06 vs. 2.20; T3, 2.18 vs. 2.15; P<0.05 ).@*Conclusions @#PAPM-based interventions for HPV vaccine hesitancy may effectively improve the awareness of HPV and HPV vaccines, reduce complacency, and enhance the influence by others among female university students.
ABSTRACT
Bladder cancer is one of the most common types of cancer. Most gene mutations related to bladder cancer are dominantly acquired gene mutations and are not inherited. Previous comparative transcriptome analysis of urinary bladder cancer and control samples has revealed a set of genes that may play a role in tumor progression. Here we set out to investigate further the expression of two candidate genes, centromere protein U (CENPU) and mitochondrial ribosomal protein s28 (MRPS28) to better understand their role in bladder cancer pathogenesis. Our results confirmed that CENPU is up-regulated in human bladder cancer tissues at mRNA and protein levels. Gain-of-function and loss-of-function studies in T24 human urinary bladder cancer cell line revealed a hierarchical relationship between CENPU and MRPS28 in the regulation of cell viability, migration and invasion activity. CENPU expression was also up-regulated in in vivo nude mice xenograft model of bladder cancer and mice overexpressing CENPU had significantly higher tumor volume. In summary, our findings identify CENPU and MRPS28 in the molecular pathogenesis of bladder cancer and suggest that CENPU enhances the progression of bladder cancer by promoting MRPS28 expression.

ABSTRACT
Chansu has demonstrated adverse reactions in clinical settings, which is associated with its toxicity and limits its clinical applications. But there are methodological limitations for drug safety evaluation. In the current study, ultra-high performance liquid chromatography, lipidomic profiling, and molecular docking were used to systemically assess Chansu-induced acute inflammatory irritation and further identify the underlying drug targets. Compared with the EtOAc extract, Chansu water fraction containing indolealkylamines caused acute inflammatory irritation in rats, including acute pain (spontaneous raising foot reaction), and inflammation (paw edema). At the molecular level, lipids analysis revealed significantly higher levels of pro-inflammatory mediators of the COX and LOX pathways. However, anti-inflammatory mediators from the CYP 450, ALA, and DHA pathways markedly decreased after exposure to Chansu water fraction. Moreover, four indolealkylamines from Chansu showed a high theoretical affinity to a known irritation target, 5-HT

BACKGROUND: Urban barrier-free facilities are imperfect in China, but visually impaired people need barrier-free facilities urgently. OBJECTIVE: To understand the public’s cognition and problems about urban barrier-free facilities, and put forward improvement suggestions by researching the application status of barrier-free facilities in Shijiazhuang (taking tactile ground surface indicator as an example). METHODS: One hundred and eighteen citizens and 51 ordinary sanitation workers at Shijiazhuang were randomly selected, and underwent cognitive survey by questionnaire. Meanwhile, 60 visually impaired persons were tactile ground surface indicator using survey by questionnaire. RESULTS AND CONCLUSION: Most citizens, sanitation workers and visually impaired person have a certain understanding of tactile ground surface indicator, but the awareness rate is still low. Totally 7% citizens and 18% sanitation workers did not know the tactile ground surface indicator, and the travel rate of visually impaired people was extremely low, only 38% visually impaired person were able to travel frequently. More than 50% people thought that the tactile ground surface indicator had not actually effect. Only 19% citizens were more satisfied with the supervision, maintenance and maintenance of the tactile ground surface indicator. 56% visually impaired people believed that it had no practical effect, and 42% visually impaired people said that their travel range was less than 1 km. It means that the public cognition rate and the tactile ground surface indicator utilization rate are low. We also put forward improvement suggestions from three aspects: Strengthening publicity education and training, rehabilitation training for the visually impaired persons, strengthen construction and maintenance, so as to protect the rights and interests for disabled people, promote them return to society and improve their quality of life.
ABSTRACT
Malignant tumor is a disease that severely threaten human health. Common chemotherapeutical drugs currently used in clinical practice have some problems in severe side effects and chemoresistance. In contrast, natural venom peptides and artificially designed targeting peptides have excellent biological activities and potential druggability due to their small molecular weights and high affinity to tumor tissues. Thus, the methods for the discovery of anti-tumor peptides have attracted much attention. In this paper, we summarized the types of anti-tumor peptides from recent literatures. Then, we systematically reviewed screening theories, methods and applications based on traditional chromatographic separation, peptidomics, phage display, phenotypic screening, and artificial intelligence. These strategies and technologies will provide a methodological reference for accelerating anti-tumor peptides research.
ABSTRACT
Abstract Objective: This study aims to replicate the phenotype of Ltbp1 knockout mice in zebrafish, and to address the function of LTBP1 in craniofacial development. Methods: Whole mount in situ hybridization (WISH) of ltbp1 was performed at critical periods of zebrafish craniofacial development to explore the spatial-temporal expression pattern. Furthermore, we generated morpholino based knockdown model of ltbp1 to study the craniofacial phenotype. Results: WISH of ltbp1 was mainly detected in the mandibular jaw region, brain trunk, and internal organs such as pancreas and gallbladder. And ltbp1 colocalized with both sox9a and ckma in mandibular region. Morpholino based knockdown of ltbp1 results in severe jaw malformation. Alcian blue staining revealed severe deformity of Meckel's cartilage along with the absence of ceratobranchial. Three-dimension measurements of ltbp1 morphants jaws showed decrease in both mandible length and width and increase in open mouth distance. Expression of cartilage marker sox9a and muscle marker ckma was decreased in ltbp1 morphants. Conclusions: Our experiments found that ltbp1 was expressed in zebrafish mandibular jaw cartilages and the surrounding muscles. The ltbp1 knockdown zebrafish exhibited phenotypes consistent with Ltbp1 knockout mice. And loss of ltbp1 function lead to significant mandibular jaw defects and affect both jaw cartilages and surrounding muscles.

Background: Apatinib has been approved for the treatment of advanced gastric adenocarcinoma and gastric-esophageal junctional adenocarcinoma, but its efficacy is unknown for other advanced solid tumors. Aims and Objectives: We retrospectively reviewed the use of apatinib for multiple advanced-stage non-gastric cancers. Ninety-two patients from 7 hospitals who received additional treatment except apatinib more than once were enrolled. Materials and Methods: The primary end-point was the overall response rate (ORR), and the secondary end-points included progression-free survival (PFS), disease control rate (DCR), overall survival, and adverse reactions. We categorized all the patients into six groups according to their cancer type. Results: In the lung cancer group, the ORR was 9% (95% confidence interval [CI], 3%–23%), DCR was 88% (95% CI, 74%–96%), and median PFS was 3 months (95% CI, 1.9–5.4 months). In the cervical cancer group, the ORR was 25% (95% CI, 3%–65%), DCR reached 100%, and median PFS was 3.5 months (95% CI, 0.6–9.0 months). There were different ORRs between the other cancer groups. In addition, the most common adverse effect of apatinib was palmar–plantar erythrodysesthesia syndrome (37%), followed by proteinuria (14%) and hypertension (13%). Conclusion: These results suggest that apatinib might be effective for not only gastric cancer but also other carcinomas including lung cancer, colorectal cancer, cervical cancer, liver cancer, breast cancer, and nasopharyngeal cancer. Thus, apatinib is a promising targeted drug for multiple types of cancer
ABSTRACT
Left atrial diameter (LAD) has been considered an independent risk factor for atrial fibrillation (AF) relapse after pulmonary vein isolation (PVI). However, whether LAD or other factors are more predictive of late recurrence in patients with paroxysmal AF remains unclear. We aimed to evaluate the value of pulmonary vein (PV) parameters for predicting AF relapse 1 year after patients underwent cryoablation for paroxysmal AF. Ninety-seven patients with paroxysmal AF who underwent PVI successfully were included. PV parameters were measured through computed tomography scans prior to PVI. A total of 28 patients had recurrence of AF at one-year follow-up. The impact of several variables on recurrence was evaluated in multivariate analyses. LAD and the time from first diagnosis of AF to ablation maintained its significance in predicting the relapse of AF after relevant adjustments in multivariate analysis. When major diameter of right inferior pulmonary vein (RIPV) (net reclassification improvement (NRI) 0.179, CI=0.031-0.326, P<0.05) and cross-sectional area (CSA) of RIPV (NRI: 0.122, CI=0.004-0.240, P<0.05) entered the AF risk model separately, the added predictive capacity was large. The accuracy of the two parameters in predicting recurrence of AF were not inferior (AUC: 0.665 and 0.659, respectively) to echocardiographic LAD (AUC: 0.663). The inclusion of either RIPV major diameter or CSA of RIPV in the model increased the C-index (0.766 and 0.758, respectively). We concluded that major diameter of RIPV had predictive capacity similar to or even better than that of LAD for predicting AF relapse after cryoablation PVI.

ABSTRACT Folium Eriobotryae, the dried leaves of loquat (Eriobotrya japonica, (Thunb.) Lindl., Rosaceae), is a traditional Chinese medicine used to treat cough with phlegm in China. Fallen and growing loquat leaves were tested for their effect on coughing and expectoration in mice. HPLC-ELSD and HPLC-MS analyses of aqueous and ethanol extracts of fallen or growing leaves were used to identify the chemical components responsible for this effect. Both the aqueous and ethanol extracts of growing and fallen leaves of loquat contained antitussive and expectorant activities. Moreover, an aqueous extract of growing loquat leaves with a higher flavonoid content displayed a stronger expectorant activity while the ethanol extract of fallen loquat leaves that contained a higher content of triterpenoid acids induced a stronger antitussive activity.
ABSTRACT
@# Objective: To compare the safety and efficacy of bevacizumab plus cisplatin and cisplatin alone in the treatment of malignant pleural effusion of lung cancer patients. Methods: From November 2014 to November 2017, 27 patients diagnosed with lung cancer complicated with malignant pleural effusion at the department of Oncology, the Central Hospital of Huludao, were enrolled in this study. Fourteen patients received bevacizumab plus cisplatin and thirteen patients received cisplatin alone. The clinical efficacy and adverse reactions were compared between the two groups. Results: There was no significant difference in the general condition between the two groups before treatment(P>0.05). The bevacizumab group had better short-term efficacy than the cisplatin group and the difference was statistically significant(92.9% vs 61.5%, P<0.05). The main adverse reactions during the treatment were bone marrow suppression and gastrointestinal discomfort, etc. The incidence of adverse reactions was similar between the two groups, with no statistically significant difference(P>0.05). Conclusion: Compared with cisplatin alone, bevacizumab combined with cisplatin has better shortterm efficacy in the treatment of lung cancer patients with malignant pleural effusion. The adverse reactions were quite similar.

ABSTRACT
<p><b>OBJECTIVE</b>To study the change in ultrastructure of C6 glioma cells after photodynamic therapy (PDT), to compare morphological differences in necrosis and apoptosis before and after PDT treatment, and to evaluate the effect of photodynamic therapy on the blood brain tumor barrier (BTB) of C6 glioma.</p><p><b>METHODS</b>The model was produced by transplanting C6 glioma cells cultured in vitro using Peterson method into the caudate nuclei of Wister rats. The experiment group received PDT for two weeks after the operation. The sub-cellular structure, blood-brain-barrier (BBB) and BTB in both groups were observed under electron microscope.</p><p><b>RESULTS</b>Apoptosis in different phases and necrosis could be observed in some C6 glioma cells. Swelling occurred on the ultrastructure of cellular organs such as mitochondria and endoplasmic reticulum in most of the cells. Damage to the BTB, reduction of the number of cellular organs in endothelial cells of the capillary blood vessels, stretch of the tight junction, and enlargement of the gaps between endothelial cells were also seen in the experiment group. Meanwhile, limited impact on the normal sub-cellular structures and BBB was observed.</p><p><b>CONCLUSION</b>PDT could induce apoptosis and necrosis of C6 glioma cells due to the damage to the ultrastructure of mitochondria and endoplasmic reticulum. The weakened function of C6 glioma BTB initiated by PDT makes it possible to perform a combined therapy of PDT and chemotherapy for glioma.</p>
