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

Ferroptosis is an iron-dependent cell death caused by phospholipid peroxidation damage of polyunsaturated fatty acids on cell membranes and involves several pathways, including the iron homeostasis regulatory pathway, the cystine glutamate reverse transporter (system Xc) pathway and the voltage-dependent anion channel (VDAC) pathway. Ferroptosis is involved in the development of several diseases (e. g. myocardial infarction, stroke, cancer and degenerative diseases). The ubiquitination is an important post-translational modification of various protein molecules in the organism. Studies have shown that regulating the ubiquitination of ferroptosis pathway-related molecules can control cellular ferroptosis. Targeting the ubiquitination of ferroptosis pathway-related molecules can effectively promote or inhibit ferroptosis, which is expected to be a new strategy for the treatment of cancer or cardiovascular diseases. In this paper we review the progress of the ferroptosis pathways and the ubiquitination modification of ferroptosis-related molecules.

ABSTRACT

OBJECTIVES@#To study the characteristics of vincristine-induced peripheral neuropathy (VIPN) in children with acute lymphoblastic leukemia (ALL) and the factors influencing the development of VIPN.@*METHODS@#The children with ALL, aged 1-18 years, who were treated with CCCG-ALL2015 or CCCG-ALL2020 regimen in the Affiliated Hospital of Guizhou Medical University from January 2018 to February 2022 were enrolled as subjects. According to the influence of age on risk, the children were divided into 1-10 years group with 91 children and >10 years group with 29 children. VIPN was graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (5th edition), and the incidence rate, severity, and type of VIPN were compared between different groups.@*RESULTS@#A total of 120 children were enrolled in this study, among whom 56 (46.7%) developed VIPN. The >10 years group had a significantly higher incidence rate of VIPN than the 1-10 years group (69% vs 40%, P<0.05). Among the 56 children with VIPN, 12 (21%) had grade 3 VIPN or above, and 44 (79%) had grade 2 VIPN. There were 77 cases of autonomic nerve symptoms (59.7%), 42 cases of peripheral nerve injury (32.5%), and 10 cases of cranial nerve injury (7.8%). There were no significant differences in the severity and type of VIPN between the groups with different ages, sexes, degrees of risk, or treatment regimens (P>0.05). The results of binary logistic regression analysis showed that age is the influencing factor for the occurrence of VIPN (P>0.05).@*CONCLUSIONS@#There is a relatively high incidence rate of VIPN in children with ALL, with the highest incidence rate of autonomic nervous symptoms. The incidence of VIP in children over 10 years old is relatively high.

ABSTRACT

Objective::To study the chemical structure and morphological features of a polysaccharide BHP-1 isolated and purified from the bulbs of Lilium davidii var. unicolor. Method::Thermogravimetry (TG) and scanning electron microscopy (SEC) was used to determine the thermal characteristics and the surface morphology changes of the polysaccharide BHP-1, respectively. The chemical structure of BHP-1 was analyzed by gas chromatography-mass spectrometer (GC-MS), partial acid hydrolysis, sodium periodate oxidation-Smith degradation and nuclear magnetic resonance (NMR). Result::The results showed that the backbone of the polysaccharide BHP-1 mainly contained α-(1→4)-linked D-glucopyranosyl and β-(1→4)-linked D-mannopyanosyl, and the branches were probably linked at the O-2 and/or O-3 of the mannosyl and glucosyl residues, with T-α-D-glucopyranosyl as a terminal structure. It was a natural mannoglucose containing a small amount of O-acetyl group. BHP-1 began to degrade at 220 °C, and the degradation ended at 520 ℃, indicating a good thermal stability, smooth surface and a large number of depressions. The depressions were formed by closely interlaced and sunken sheet layers with irregular holes. Conclusion::BHP-1 was a natural mannoglucose with a good thermal stability, smooth surface, a large number of depressions and irregular holes, and contained a small amount of O-acetyl group. Its chemical structure was reported for the first time.

ABSTRACT

Thin layer chromatography, high performance liquid chromatography and multivariate statistical analysis were integrated in current study to provide a basis for the quality evaluation and the standard improvement of Paridis Rhizoma(Chinese name: Chong-lou). The results demonstrated that the primary saponins in the two authorized sources of Paridis Rhizoma were polyphyllinsⅠ, Ⅱ and Ⅶ, while the rhizome of Trillium tschonoskii an adulterant of Paridis Rhizoma was rich of polyphyllin Ⅵ. Therefore, the apparent content of polyphyllin Ⅵ plays a determinant role towards the source authentication of raw materials and decoction slices of Paridis Rhizoma, whose adulterants frequently occur in the market. Moreover, the contents of polyphyllin Ⅵ in the two authorized sources could meet the requirements of Chinese Pharmacopoeia. Therefore, we suggested that polyphyllin Ⅵ should not be omitted from the quality standard of Paridis Rhizoma in the Chinese Pharmacopoeia, and on the other side, polyphyllinsⅠ, Ⅱ and Ⅶ should be the eligible quality indicators. The study aims to sound information and evidences for the quality evaluation of Paridis Rhizoma, and also to provide a theoretical basis for the standard revision of Paridis Rhizoma in the future Chinese Pharmacopoeia.

ABSTRACT

Objective:To study the efficacy of integrative medicine on congenital muscular torticollis. Methods:From October, 2017 to September, 2019, 80 children with congenital muscular torticollis were divided into group 1 (n = 40) and group 2 (n = 40) according to different treatment schemes. Group 1 received comprehensive physiotherapy, including passive stretching, head control training, posture correction and family rehabilitation. Group 2 received Tuina in addition. Before and six months after treatment, the root mean square (RMS) of surface electromyography of bilateral sternocleidomastoid muscles in supine neutral position, neck rotation and stretch, and the range of motion of passive neck rotation and lateral flexion, and the angle of head deviation from the midline to the affected side were compared. Results:Before treatment, the RMS of sternocleidomastoid muscle in each position was lower in the affected side than in the healthy side (P < 0.01), and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side was less than that of the other side (P < 0.01) in both groups; however, no significant difference was found between two groups (P > 0.05). After treatment, the RMS of EMG of sternocleidomastoid muscle in each position, and the range of motion of neck when lateral flexion to the healthy side and rotation to the affected side improved (|t| > 3.290, P < 0.01) in both groups, and were better in group 2 than in group 1 (t > 2.401, P < 0.05); the angle of head deviation from the midline to the affected side significantly decreaed (t > 15.075, P < 0.001) in both groups, and was significantly less in group 2 than in group 1 (t = -4.971, P < 0.001). Conclusion:Integrative medicine is effective on infant with congenital muscular torticollis, which is superior to comprehensive physiotherapy only.

ABSTRACT

Morphine addiction causes the disturbance in the dopaminergic transmission. The activity of dopaminergic neurons in patients with stress depression is reduced. These studies indicate a strong correlation between morphine addiction and stress depression, which involvement of one or more common neurobiological mechanisms. The dysfunction of dopaminergic neurotransmission from the ventral tegmental area(VTA) to the nucleus accumbens (NAc), prefrontal cortex (mPFC), amygdala (Amy), hippocampus (Hip), and striatum (ST) plays an important role in regulating morphine addiction and stress depression. This article summarizes the mechanism of the dopaminergic transmission regulating morphine addiction and stress depression.

ABSTRACT

OBJECTIVE@#To comparatively study the toxicity of four metal-containing nanoparticles (MNPs) and their chemical counterparts to the air-blood barrier (ABB) permeability using an in vitro model.@*METHODS@#ABB model, which was developed via the co-culturing of A549 and pulmonary capillary endothelium, was exposed to spherical CuO-NPs (divided into CuO-40, CuO-80, and CuO-100 based on particle size), nano-Al2O3 (sheet and short-rod-shaped), nano-ZnO, nano-PbS, CuSO4, Al2(SO4)3, Zn(CH3COO)2, and Pb(NO3)2 for 60 min. Every 10 min following exposure, the cumulative cleared volume (ΔTCL) of Lucifer yellow by the model was calculated. A clearance curve was established using linear regression analysis of ΔTCL versus time. Permeability coefficient (P) was calculated based on the slope of the curve to represent the degree of change in the ABB permeability.@*RESULTS@#The results found the increased P values of CuO-40, CuO-80, sheet, and short-rod-shaped nano-Al2O3, Al2(SO4)3, and Pb(NO3)2. Among them, small CuO-40 and CuO-80 were stronger than CuO-100 and CuSO4; no difference was observed between Al2(SO4)3 and sheet and short-rod-shaped nano-Al2O3; and nano-PbS was slightly weaker than Pb(NO3)2. So clearly the MNPs possess diverse toxicity.@*CONCLUSION@#ABB permeability abnormality means pulmonary toxicity potential. More studies are warranted to understand MNPs toxicity and ultimately control the health hazards.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the parents' compliance in non-hospital settings during the operation of expressed breast milk bank.</p><p><b>METHODS</b>In September 2014, a questionnaire survey was carried out to investigate the parents' willingness about feeding the inpatient neonates with maternal expressed breast milk, to evaluate the effectiveness of the breast milk feeding supporting system, and to monitor the compliance in non-hospital settings during the delivery of maternal expressed breast milk. Improvements in education were made according to the results. A second survey was done in September 2015.</p><p><b>RESULTS</b>A total of 340 questionnaires were sent out, and 338 usable questionnaires were returned. According to the time when the questionnaires were sent out, they were divided into two groups: 2014 group (n=229) and 2015 group (n=109). The age of most mothers was 20-30 years in the 2014 group and 30-40 years in the 2015 group. Most mothers delivered at the West China Second Hospital of Sichuan University in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (74.3% vs 61.6%; P<0.05). Guidance was given to mothers in the presence of insufficient breast milk production in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (91.7% vs 79.9%; P<0.05). Both groups had good family compliance in the collection, storage, and transport of breast milk. There were no significant differences in their compliance with washing hands, sterilizing instruments, and using a clean special refrigerator between the two groups. The expressed breast milk was transported strictly according to the procedure in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (100% vs 87.1%; P<0.05).</p><p><b>CONCLUSIONS</b>Before and after improvements in the health education, most parents have good compliance in the collection, storage, and transport of breast milk.</p>

ABSTRACT

<p><b>BACKGROUND</b>Polypharmacy and potentially inappropriate medications (PIMs) are prominent prescribing issues in elderly patients. This study was to investigate the different prevalence of PIM use in elderly inpatients between 65-79 years of age and 80 years or older, who were discharged from Geriatric Department in West China Hospital.</p><p><b>METHODS</b>A large-scale cohort of 1796 inpatients aged 65 years or over was recruited. Respectively, 618 patients were 65-79 years and 1178 patients were 80 years or older. Updated 2012 Beers Criteria by the American Geriatric Society was applied to assess the use of PIM among the investigated samples.</p><p><b>RESULTS</b>A review of the prescribed medications identified 686 patients aged 80 years or older consumed at least one PIM giving a rate of 58.2%. Conversely, 268 (43.4%) patients aged 65-79 years consumed at least one PIM (χ2 = 40.18, P < 0.001). Patients aged 80 years or older had higher hospitalization expenses, length of stay, co-morbidities, medical prescription, and mortality than patients aged 65-79 years (all with P < 0.001). Patients aged 80 years or older were prescribed with more benzodiazepines, drugs with strong anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin. In multiple regression analysis, PIM use was significantly associated with female gender, age, number of diagnostic disease, and number of prescribed medication.</p><p><b>CONCLUSIONS</b>The finding from this study revealed that inpatients aged 80 years or older encountered more PIM use than those aged 65-79 years. Anticholinergic properties, megestrol, antipsychotics, theophylline, and aspirin are medications that often prescribed to inpatients aged 80 years or older. Doctors should carefully choose drugs for the elderly, especially the elderly aged 80 years or older.</p>

ABSTRACT

The output and agronomic characters of 3-year-old Panax notoginseng cultured under stereo structure (upper, middle and down layers) were investigated, and the annual change of N, P and K of its planting soil were also studied. Results showed that, compared with field cultured Panax notoginseng, growth vigour and output of stereo-cultivation were significantly lower. But the total production of the 3 layers was 1.6 times of field. The growth vigor and production of P. notoginseng was in the order of upper layer > middle layer > down layer. The content of ginsenoside in rhizome, root tuber and hair root of P. notoginseng was in the order of upper layer > field > middle layer > down layer. Organic matter content and pH of stereo-cultivation soil decreased with the prolonging of planting time, which with the same trend of yield. Organic matter content of stereo-cultivation soil was significantly higher than field, but the pH was significantly lower. Contents of total and available N, P and K in stereo-cultivation soil and field decreased with the prolonging of planting time. The content of N and P were in the order of upper layer > middle layer > yield > down layer, the content of K was in the order of upper layer > middle layer > down layer > yield. Compared with field, the proportion of N and P in the organ of underground (rhizome, root tuber and hair root) of upper layer were increased, while decreased in middle and down layers. Proportion of K in underground decreased significantly of the 3 layers. In conclusion, the agronomic characters and production of stereo-cultivation were significantly lower than that of yield. But the total production of the 3 layers were significantly higher than field of unit area. And the aim of improving land utilization efficiency was achieved. Nutritions in the soil of stereo-cultivation were enough to support the development of P. notoginseng, which was not the cause of weak growth and low production. The absorbing ability of P. notoginseng to N, P and K nutrients was decreased by stereo-cultivation mode. So, improve the growth vigour of P. notoginseng from the perspective of adjusting the stereo-cultivation mode so as to improve the nutrient absorption capacity is the future direction.

ABSTRACT

Light intensity, gas temperature, soil temperature and gas exchange parameters were determined of three years old Panax notoginseng planted on different layers seedbed and different location (left, middle, right) of the same layer in greenhouse. Result show that diurnal variation of light intensity, gas temperature and soil temperature showed that upper layer > middle layer > lower layer; different locations of the same layer showed that light intensity of upper layer was not different among different locations; light intensity of middle and lower layer in right and left were the same, and significantly higher than those in the middle position; the gas temperature of each layer all with less different of each location; soil temperature of 12 cm depth is the lowest, and was gradually increased to the upper and lower surface; net photosynthetic efficiency of P. notoginseng showed that upper layer > middle layer > lower layer; there were significant correlation between soil temperature, stomatal conductance, intercellular CO2 concentration and photosynthetic rate were correlated with light intensity significantly; transpiration rates had notable correlation with light intensity and gas temperature. All above indicated that net photosynthesis rate of P. notoginseng was affected by light intensity directly, gas temperature and soil temperature indirectly. Inconclusion, stereoscopic cultivation of P. notoginseng was practicable in present study. The planting quality of P. notoginseng under stereoscopic cultivation could be improved by ameliorate the structure of seedbed to enhance the light intensity of middle and lower layer. Increase the thickness of the seedbed to decrease the temperature difference of soil. Further the management of ventilation facilities of greenhouse to control the gas temperature.
