Objective:To investigate the extent and characteristics of parenting stress experienced by fathers of children aged 0-6 in three provinces of Eastern China, and to compare the quality of their marital relationships within each latent class, in order to provide reference for developing intervention strategies for different categories of fathers.Methods:Using cross-sectional survey methods, fathers with children aged 0-6 years were recruited using convenience sampling from December 2020 to March 2021 from Anhui province, Zhejiang province and Jiangsu province in Eastern China. Data were collected through a general information questionnaire, the Parenting Stress Index-Short Form, and the Locke-Wallace Marital Adjustment Scale.Latent profile analysis was used to determine the classification, Kruskal-Wallis H test was used to compare the difference of marital quality. Results:A total of 657 questionnaires were distributed and 604 valid questionnaires were recovered. The age of 604 fathers was (32.50 ± 6.26) years, the score of parenting stress was (89.70 ± 17.87) and the score of marriage quality was (108.36 ± 22.28). The characteristics of parenting stress among fathers of young children were categorized into three latent profile types: "high stress-negative parenting group" (88 people accounting for 14.6%), " medium stress- poor interaction group" (329 people accounting for 54.5%), and " low stress-positive parenting group" (187 people accounting for 30.9%). The scores of marriage quality were (99.94 ± 23.81), (106.52 ± 19.84), (115.56 ± 23.70) points among these three latent classes with significant differences ( H=35.89, P<0.05). Conclusions:The study identifies three latent classes of parenting stress among fathers of children aged 0-6, each associated with varying levels of marriage quality. Therefore, targeted interventions aimed at improving fathers′ parenting stress and marriage quality, and helping create family environments where children can grow up healthy.

Objective To study the syntactic impairment characteristics of wh-question comprehension and expression in Chinese non-fluent aphasic patients.Methods The differences in comprehension and expression be-tween 25 non-fluent aphasic patients and 25 normal subjects were tested in the form of sentence-figure matching and elicitation-repetition to analyze syntactic impairment characteristics related to sentence patterns,question objects,and question words.Results The patients with non-fluent aphasia had impaired comprehension and expression of specific interrogative sentences,and the order of correct comprehension was:(active interrogative sentence,object pseudo-split interrogative sentence)＞(subject pseudo-split interrogative sentence,passive interrogative sentence),and the order of correct expression was:active interrogative sentence＞(pseudo-split interrogative sentence,pas-sive interrogative sentence).Conclusion The pattern of impaired comprehension and expression of wh-question was similar in patients with Chinese non-fluent aphasia.The main influences on syntactic structure included the object of questioning(subject-object)and the type of sentence.Obstacles were more pronounced in sentences with wh-move-ment and non-canonical order.

Patients with specific language impairment(SLI)have normal intelligence but experience difficul-ties in language comprehension and expression.At present,the cause of the disease has not been determined,and only a few potential causes are being discussed,among which the relationship between auditory processing abilities and language problems of this group has attracted much attentions.An increasing number of studies employ electro-physiological techniques to investigate the auditory processing abilities of SLI patients,accumulating substantial evi-dence.Therefore,this study reviewed empirical research on the auditory processing abilities of SLI patients from the perspectives of auditory brainstem response,middle-latency response,and long-latency response.It aims to eluci-date the characteristics of auditory processing in SLI patients,analyze its relationship with language disorders,and offer insights into the diagnosis and treatment of SLI patients.

Children with specific language impairment(SLI)have normal cognitive abilities but experience language deficits.The heterogeneity of language disorders makes SLI children optimal subjects for investigating the correlation between language ability and theory of mind.This paper provides a comprehensive review of foreign em-pirical studies examining the relationship between language ability and theory of mind in SLI groups from various perspectives.The findings indicate that specific types of language disorders exhibit delayed development in theory of mind,which is closely associated with their language ability deficits.Among all linguistic elements,syntactic de-fects demonstrate the most concentrated evidence regarding their impact on theory of mind.It is noteworthy that al-though SLI children offer valuable insights into the correlation between language and theory of mind,further investi-gation is still required to comprehensively comprehend this association.The present study also provides recommenda-tions for future research endeavors in this domain.

Objective:To explore the effect of comprehensive geriatric assessment-based family empowerment program combined with tongue three-needle in dysphagia after senile stroke.Methods:From February 2017 to February 2019, we selected 50 senile stroke patients with dysphagia in Harrison International Peace Hospital. All patients were randomly divided into experimental group and control group, 25 cases in each group.Experimental group used the comprehensive geriatric assessment-based family empowerment program combined with tongue three-needle for treatment, and control group was treated with the simple tongue three-needle. We compared the swallowing function, velocity of hyolaryngeal excursion, nutritional status and treatment effect of patients between two groups before and after treatment.Results:After intervention, scores of Water Swallowing Test and Videofluoroscopic Swallowing Study of patients of both groups were lower than those before intervention, and scores of Water Swallowing Test and VFSS of patients in experimental group were lower than those in control group with statistical differences ( P<0.05) . The score of Min Nutrition Assessment Short Form (MNA-SF) , serum albuminand hemoglobin of experimental group were better than those of control group with statistical differences ( P<0.01) . The total effective rate of experimental group was higher than control group also with a statistical difference ( P<0.01) . Conclusions:The use of comprehensive geriatric assessment-based family empowerment program combined with tongue three-needle in dysphagia after senile stroke can significantly improve patients' swallowing function, promote the physical recovery of patients which has high clinical application value.

OBJECTIVETo evaluate the inhibitory effect of total bufadienolides from toad venom against H22 tumor in mice and preliminarily analyze the structures of the metabolites in tissues.

METHODHPLC and LC-MS were used for analysis of the chemical composition of TBFs. High, middle and low dosages of TBFs were orally administered or intra-peritoneally injected to H22 tumor-bearing mice for thirteen days. The animals were killed and the tumors were stripped and weighed. The metabolites in the tissues such as heart, liver, spleen, lung and kidney, were analyzed by HPLC and LC-MS.

RESULTThe chemical composition of TBFs were identified by comparison of the retention times with those of reference substances, on-line UV spectra and MS data. Its main components are concerned with gamabufotalin, arenobufagin, bufotalin, resibufagin, cinobufotalin, bufalin, cinobufagin and resibufogenin. TBFs had no obvious influence on body weight of H-22 tumor-bearing mice orally administered and the inhibition rate against tumor were 14.76%, 16.38% and 10.32% for low (5 mg x kg(-1)), middle (10 mg x kg(-1)) and high dosage (20 mg x kg(-1)), respectively. The mice intra-peritoneally injected with middle and high-dose of TBFs gained body weight slower than the control mice on the 5th day and recovered on the 13th day. The inhibition rate against tumor were 17.30%, 19.80% and 40.95% for low (1.5 mg x kg(-1)), middle (3 mg x kg(-1)) and high dose (6 mg x kg(-1)), respectively. The inhibitory effect took on dose-dependent manner. Based on the HPLC analyses on heart, liver, spleen, lung and kidney, bufadienolides were found in the liver tissue and 11 compounds of them were tentatively identified by LC-DAD-MS.

CONCLUSIONTBFs by oral administration had no inhibitory effect against H22 tumor in mice, however, TBFs by intra-peritoneal injection displayed the significantly inhibitory effect, accompanying some toxicity for early duration of the study. The identification of bufadienolides in the liver provides a good basis for the further investigation of the metabolic pathways of TBFs in vivo.
