ABSTRACT

In order to systematically evaluate the safety of Sanfu acupoint herbal patching, CNKI, SinoMed, VIP, Wanfang, PubMed, Medline, EMbase, and Cochrane Library were searched in accordance with PICOS principles, with a time limit from database establishment to December 2019. Meta-analysis was used for a single-group rate analysis and a weighted combination of these two groups on rates of adverse reactions. A total of 9 articles meeting the inclusion criteria were included in the analysis, involving 2 119 patients. The single-group rate Meta-analysis showed that the adverse reactions incidence was 9% in the treatment group(OR=0.10,95%CI[0.06, 0.19], P<0.000 01), and 9% in the control group(OR=0.10, 95%CI[0.07, 0.13], P<0.000 01). In combined statistics of all samples OR=1.81, 95%CI[1.04, 3.15], P=0.04, the incidence of adverse reactions in the treatment group was slightly higher than that of the control group. In the subgroup analysis, the incidence of adverse reactions in terms of both single-group rate and weighed rate in the treatment group was higher than that in the control group in the asthma subgroup, rhinitis subgroup, ≥18 years old subgroup, and application time 2 h subgroup, with statistically significant differences(P<0.05). The results of the Meta-analysis and systematic review suggested that the incidence of adverse reactions in clinical use of the Sanfu acupoints herbal patching was relatively low. The main types of adverse reactions were skin ulcers, blisters and other skin symptoms. The symptoms were relatively mild, which could be relieved by drug withdrawal or symptomatic treatment. It shows that the safety of the Sanfu acupoint herbal patching was relatively high, and the occurrence of adverse reactions was related to the original disease and age, mainly in asthma and rhinitis or patients over 40 years old. Affected by clinical heterogeneity, the conclusions of the application time subgroup need to be further improved.

ABSTRACT

Objective@#To provide an automatic method for segmentation and diameter measurement of type B aortic dissection (TBAD). @*Materials and Methods@#Aortic computed tomography angiographic images from 139 patients with TBAD were consecutively collected. We implemented a deep learning method based on a three-dimensional (3D) deep convolutional neural (CNN) network, which realizes automatic segmentation and measurement of the entire aorta (EA), true lumen (TL), and false lumen (FL). The accuracy, stability, and measurement time were compared between deep learning and manual methods. The intra- and inter-observer reproducibility of the manual method was also evaluated. @*Results@#The mean dice coefficient scores were 0.958, 0.961, and 0.932 for EA, TL, and FL, respectively. There was a linear relationship between the reference standard and measurement by the manual and deep learning method (r = 0.964 and 0.991, respectively). The average measurement error of the deep learning method was less than that of the manual method (EA, 1.64% vs. 4.13%; TL, 2.46% vs. 11.67%; FL, 2.50% vs. 8.02%). Bland-Altman plots revealed that the deviations of the diameters between the deep learning method and the reference standard were -0.042 mm (-3.412 to 3.330 mm), -0.376 mm (-3.328 to 2.577 mm), and 0.026 mm (-3.040 to 3.092 mm) for EA, TL, and FL, respectively. For the manual method, the corresponding deviations were -0.166 mm (-1.419 to 1.086 mm), -0.050 mm (-0.970 to 1.070 mm), and -0.085 mm (-1.010 to 0.084 mm). Intra- and inter-observer differences were found in measurements with the manual method, but not with the deep learning method. The measurement time with the deep learning method was markedly shorter than with the manual method (21.7 ± 1.1 vs. 82.5 ± 16.1 minutes, p < 0.001). @*Conclusion@#The performance of efficient segmentation and diameter measurement of TBADs based on the 3D deep CNN was both accurate and stable. This method is promising for evaluating aortic morphology automatically and alleviating the workload of radiologists in the near future.

ABSTRACT

Herpes simplex virus type 1 (HSV-1), as a pathogen usually leading to herpes labialis, has been found to cause more cases of genital herpes and be associated with the occurrence of neurological diseases such as Alzheimer′s disease (AD). AD is a chronic and progressive degenerative disease of the central nervous system, the pathogenesis of which has not been fully elucidated, and currently there is a lack of drugs that can effectively treat the disease. The hypothesis that HSV-1 infection is involved in the pathogenesis of AD has been discussed for a long time, but there is no definite evidence to prove it. This article briefly reviewed the research progress in the pathogenesis of AD caused by HSV-1.

ABSTRACT

Objective:To evaluate the feasibility of making individualized scanning and contrast injection protocol based on body mass index (BMI) and body weight during dynamic myocardial computed perfusion (CTP) imaging in order to get high-quality images while drastically reducing radiation dose.Methods:A total of 128 patients with coronary heart disease diagnosed by coronary CTA (CCTA) performed CTP from June, 2019 to March, 2020 were prospectively enrolled. Patients were divided into six groups: group 1, BMI<24 kg/m 2, ≤60 kg, 70 kV; group 2,BMI<24 kg/m 2, 61≤kg≤70, 70 kV; group 3, BMI 24-28 kg/m 2, 61≤kg≤70, 80 kV; group 4, BMI 24-28 kg/m 2, 71≤kg≤80, 80 kV; group 5, BMI 24-28 kg/m 2,>80 kg, 80 kV;group 6, BMI>28 kg/m 2,>80 kg, 100 kV. 200 mA was fixed for all patients. Contrast agent with iodine containing 370 mg/ml was used in all patients. The iodine delivery rates (IDR) for each group was 0.8, 1.0, 1.2, 1.4, 1.6, 2.0 g/s, respectively. The attenuation and noise of left ventricle (LV) and septal myocardial were measured to calculate signal to noise ratio (SNR) and contrast to noise ratio (CNR) of the images in each group. The Shapiro-Wilk test was conducted to assess the normality of quantitative data. Quantitative variables were compared using one-way ANOVA if normally distributed. Results:The LV attenuation of the six groups were (506±85), (513±77), (510±81), (456±74), (477±111), (462±43) HU, respectively. There was no significant difference among them ( F=2.249, P=0.054). SNR values of LV were 23±8, 20±5, 21±5, 19±4, 19±7, 19±4, and CNR values were 19±7, 17±4, 17±4, 16±4, 15±6, 15±4, respectively. There were no significant differences among them ( F=1.674, 1.736, all P>0.05). Under a single CTP scan, the radiation dose of 70, 80 and 100 kV groups were 1.6, 2.3 and 4.3 mSv, respectively. The does of the 70 kV group and 80 kV group were significantly lower than that of the 100 kV group, and the dose of the 70 kV group was also significantly lower than that of the 80 kV group (all P<0.001). Conclusions:The application of individualized scanning and contrast agent injection protocol based on IDR is feasible in myocardial CTP with successful image quality, and the radiation dose decreases significantly.

ABSTRACT

Objective:To probe the diagnostic performance of the combined evaluation of stenosis and plaque characteristics based on coronary computed tomography angiography (CCTA) in identification of myocardial ischemic lesions, using the invasive coronary angiography (ICA)-based fractional flow reserve (FFR) as the gold standard.Methods:From November 2018 to March 2020, the patients with suspected or known coronary artery disease and scheduled for ICA at 5 clinical trials centers were enrolled in this study. All the patients underwent CCTA, ICA and FFR in turn in one week. The luminal stenosis and plaque characteristics were measured and assessed including plaque burden, volume ratios of calcification and non-calcification, lesion length and CT vulnerable features. All culprit vessels were divided into FFR≤0.8 and FFR>0.8 groups, and the parameters of plaque characteristics were compared. The correlation of ischemic lesions with CCTA stenosis and plaque characteristics was analyzed by the logistic regression analysis. The ROC curve was used to evaluate the sensitivity and specificity of CCTA stenosis rate and plaque characteristics, meanwhile the area under curve (AUC) of each parameter was compared by Delong test.Results:Three hundred and sixty-six culprit vessels in 317 patients were analyzed in this study (169 vessels in ischemia group and 197 in nonischemia group). The plaque burden [34.3% (30.3%, 38.8%) vs. 32.4% (28.5%, 37.9%); Z=-2.622, P=0.009], proportion of CT vulnerable features [26.9% (45/169) vs.11.7% (23/197); χ 2=15.311, P<0.001] and lesion length [22.1 (14.4, 35.0) mm vs. 17.6 (11.0, 26.0) mm; Z=-4.388, P<0.001] in FFR≤0.8 group were higher than those in FFR>0.8 group. The results of logistic regression analysis revealed that CCTA stenosis, lesion length, and CT vulnerable features were significant predictors for myocardial ischemia (OR values: 3.794, 2.461, 1.027; P<0.001, P=0.002, P=0.002). The diagnostic performance of CCTA ≥50% stenosis alone in identification of ischemic lesions was low (AUC=0.625). When it combined high-risk plaque characteristics and lesion length, the AUC was improved to 0.714 with a statistical significance. Conclusions:CCTA stenosis, lesion length, and CT vulnerable features are major predictors in identification of myocardial ischemic lesions, and the combination will significantly improve the diagnostic performance of CCTA ≥50% stenosis.

ABSTRACT

Objective:To evaluate the accuracy of two-dimensional ultrasound(2D-US), three-dimensional volume ultrasound (3D-US) and ultrasound strain elastography (USE) in the measurement of preoperative tumor size of breast cancer and its influencing factors.Methods:A total of 101 patients with breast cancer in Nanfang Hospital of Southern Medical University from April to November 2016 were recruited in this study. The maximum diameter of the lesion was examined by 2D-US 3D-US and USE before core needle biopsy or surgery biopsy. The Bland-Altman analysis and intraclass correlation coefficient (ICC) were used to analyze the consistency between the ultrasonic technique measurements and the pathological measurements of postoperative lesion. Chi-square test or Fisher exact test was used to analyze whether the accuracy of three imaging techniques was affected by different clinical pathologic factors and imaging characteristics.Results:3D-US showed better agreement with histology than 2D-US and USE, with a higher ICC (ICC 3D-US=0.90>ICC 2D-US=0.81>ICC SUE=0.78) and low variation. In 3D-US, the accuracy rate of the age >40 years old group was higher than ≤40 years old group. In 2D-US, the measurement accuracy of invasive ductal carcinoma (IDC) without intraductal carcinoma in situ (DCIS) group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. The long diameter of lesion ≤2 cm group was more accurate than >2 cm group, IDC group was more accurate than invasive lobular carcinoma(ILC) group. In USE, the measurement accuracy of IDC without DCIS group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. All the differences mentioned above were statistically significant(all P<0.05). Conclusions:For accurate measurement of the size of breast cancer lesions, 3D-US is the best, which is least affected by clinicopathological factors and imaging features, followed by 2D-US and USE. This has certain significance for clinically determining the extent of breast cancer lesions.

ABSTRACT

Objective:To explore the clinical significance of the combined detection of Clara cell secretory protein 16 (CC16) and soluble receptor for advanced glycation end product (sRAGE) in the diagnosis and prognosis of acute respiratory distress syndrome (ARDS).Methods:100 ARDS patients admitted to the intensive care unit (ICU) of Chu Hsien-I Memorial Hospital of Tianjin Medical University from July 2019 to September 2020 were enrolled as the ARDS group, and 100 non-ARDS patients admitted to the ICU during the same period were enrolled as the control group. The general information, vital signs, blood gas analysis, serum CC16 and sRAGE levels, duration of mechanical ventilation, length of ICU stay and prognosis during hospitalization were collected. The receiver operating characteristic (ROC) curve was drawn and the area under ROC curve (AUC) was calculated to evaluate the clinical value of CC16 and sRAGE lonely or combination in the diagnosis and prognosis of ARDS.Results:The duration of mechanical ventilation in the ARDS group was significantly longer than that in the non-ARDS group (days: 15.44±3.04 vs. 12.61±3.73, P < 0.01), and the hospitalization mortality was higher (38.0% vs. 9.0%, P < 0.01), but there was no significant difference in gender, age, body mass index (BMI), acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score or the length of ICU stay between the two groups. There were 62 ARDS patients survived and 38 ARDS patients died during hospitalization. The APACHEⅡ score of the death group was significantly higher than that of the survival group (23.55±2.83 vs. 19.40±4.10, P < 0.01), but there was no significant difference in age, BMI, oxygenation index, mean arterial pressure, duration of mechanical ventilation or the length of ICU stay between the two groups. The serum levels of CC16 and sRAGE in the ARDS group were significantly higher than those in the non-ARDS group [CC16 (mg/L): 38.78±14.70 vs. 21.87±2.45, sRAGE (pg/L): 2 470.95±288.70 vs. 2 013.22±131.15, both P < 0.01]; and the serum levels of CC16 and sRAGE of ARDS patients in the death group were significantly higher than those in the survival group [CC16 (mg/L): 42.02±10.81 vs. 30.52±9.47, sRAGE (pg/L): 2 638.34±324.07 vs. 2 279.91±163.70, both P < 0.01]. ROC curve showed that the AUC of CC16 and sRAGE in the diagnosis of ARDS alone were 0.859 [95% confidence interval (95% CI) was 0.808-0.911] and 0.821 (95% CI was 0.762-0.879), and the best cut-off values were 25.76 mg/L and 2 203.00 pg/L, respectively; the AUC of combined detection of CC16 and sRAGE was 0.932 (95% CI was 0.900-0.965) with the sensitivity of 89.0% and the specificity of 87.6%. The AUC of CC16 and sRAGE in predicting the death of patients with ARDS during hospitalization were 0.747 (95% CI was 0.651-0.843) and 0.819 (95% CI was 0.737-0.902), and the best cut-off values were 32.95 mg/L and 2 554.50 pg/L, respectively; the AUC of combined detection of CC16 and sRAGE was 0.900 (95% CI was 0.828-0.972) with the sensitivity of 88.7% and the specificity of 84.5%. Conclusions:Serum CC16 and sRAGE have clinical value for the diagnosis and prognosis of ARDS. The combined detection of them is superior to individual detection for early prediction of ARDS and prognosis.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree with suspected mitochondrial functional defects through combined next-generation sequencing (NGS), copy number variation sequencing (CNV-seq), and mitochondrial DNA (mtDNA) sequencing.@*METHODS@#Clinical data of the proband and his family members were collected. The patient and his parents were subjected to family-trio whole-exome sequencing (WES), CNV-seq and mtDNA variant detection. Candidate variant was verified by Sanger sequencing.@*RESULTS@#Trio-WES revealed that the proband has carried compound heterozygous variants of the NDUFS1 gene, including a paternally derived c.64C>T (p.R22X) nonsense variant and a maternally derived c.845A>G (p.N282S) missense variant. Both variants may cause loss of protein function. No variant that may cause the phenotype was identified by CNV-seq and mtDNA variant analysis.@*CONCLUSION@#Children with suspected mitochondrial disorders may have no specific syndromes or laboratory findings. A comprehensive strategy including mtDNA testing may facilitate the diagnosis and early clinical interventions.

ABSTRACT

BACKGROUND: Protein degradation is the main reason of exercise induced muscle damage (EIMD). High-intensity exercise may lead to the misfolding of proteins and form aggregates, which is harmful to the ultrastructure of skeleton muscle. OBJECTIVE: To determine the formation and role of protein aggregate (especially the desmin aggregate) in EIMD. METHODS: Sixty-four adult male Sprague-Dawley rats (purchased from Beijing Vital River Laboratory Animal Technology Co., Ltd., China) were randomly divided into eight groups (control, post-exercise 0, 3, 6, 12, 24, 48, and 72 hours, eight rats in each). A damage model was established by downhill running (-16°, 16 m/min, 90 minutes). All rats were then killed at corresponding time points to take the soleus as specimen. Severity of damage was observed histologically under a transmission electron microscope. Expression of ubiquitin in the insoluble protein of soleus muscle was detected using western blot, and expression of desmin aggregates was observed by immunofluorescence double labeling. All experimental procedures were approved by the Beijing Sport University Institutional Review Board. RESULTS AND CONCLUSION: (1) After a large-load eccentric exercise, the sarcomere of the soleus muscle was widened, the Z-line was broken, and the myofibril was broken and distorted, all of which was most serious at 12 hours after exercise, and recovered completely at 72 hours after exercise. (2) Western blot results indicated that the expression of ubiquitin in the skeletal muscle increased first and then decreased after a large-load eccentric exercise. The expression peaked at 12 hours after exercise and returned to normal at 72 hours after exercise. (3)Overall expression of desmin aggregates significantly raised (P < 0.01) instantly when the EIMD occurred. It reached the peak at 12 hours after exercise, then reduced somewhat (P < 0.01) at 24 and 48 hours, and finally recovered at 72 hours. (4)These findings indicate that desmin aggregation may be one of the causes of EIMD.

ABSTRACT

BACKGROUND: A high-intensity eccentric exercise may lead to skeletal muscle damage, endoplasmic reticulum stress, increasing misfolded proteins. Aggrephagy works as an effective way of controlling quality of proteins and plays an important role in damage repair. OBJECTIVE: To discover the activation degree of aggrephagy in the damage repair process after an overload eccentric exercise, and to discuss the role of aggrephagy in the exercise-induced muscle damage, which is supplementary to the protein degradation pathway in skeletal muscle damage. METHODS: Sixty-four male adult Sprague Dawley rats were randomly divided into a static control group (n=8) and seven exercise groups according to post-exercise time (0, 3, 6,12, 24,48 and 72 hours, eight rats in each). Damage models were established by downhill running (-16°, 16 m/min, 90 minutes). Subsequently, the histological changes of the rat soleus muscle was observed under an electron microscope and protein expressions of histone deacetylase 6 and microtubule-associated protein 1 light chain 3II/I related to aggrephagy were detected using western bot assay. RESULTS AND CONCLUSION: (1) Under the transmission electron microscope, the rat soleus muscle was disordered and widened and appeared to have transient sarcomere, the Z line was water wave-like, broken and disappeared, and the mitochondria were swollen and unevenly distributed with an unclear structure after high-intensity eccentric exercise. The model rats suffered severest muscle damage at 12 hours and recovered completely at 72 hours after high-intensity eccentric exercise. (2) After one-time eccentric exercise, the expression of histone deacetylase 6 had a transient increase. The histone deacetylase 6 expression reached the peak at 6 hours, then gradually reduced and recovered at 72 hours after exercise. The microtubule-associated protein 1 light chain 3II/I expression was significantly increased at 3 hours after exercise, reached the peak at 12 hours, then reduced significantly and recovered at 72 hours after exercise. All these findings indicate that aggrephagy transiently happens and exerts important roles in the clearance of misfolded proteins, maintenance of cellular environmental homeostasis and recovery of skeletal muscle damage.

ABSTRACT

In this study, the clinical characteristics and drug combination rules of Danshen Chuanxiongqin Injection in the treatment of patients with cerebral infarction were analyzed. The inpatient information of 2 857 patients of cerebral infarction treated with Danshen Chuanxiongqin Injection in HIS database of 20 grade Ⅲ class A hospitals in China was collected, and a model was established by description analysis and Apriori algorithm, in order to explore the clinical characteristics and drug combination rules of Danshen Chuan-xiongqin Injection in the treatment of cerebral infarction. The results showed that among patients of cerebral infarction treated with Danshen Chuanxiongqin Injection, 1 727 patients were older than 65 years old, accounting for 69.61%, and 1 610 were males, accounting for 63.59%. Commonly used drugs included lipid-lowering agents, anticoagulant thrombolytic agents, antiplatelet agents, stimulants of brain metabolism, vasodilators and other Western drugs, as well as traditional Chinese medicines, such as blood-activating agents, heat-clearing agents and expectorant agents. The Western medicine with the highest use frequency in combination with Danshen Chuan-xiongqin Injection was aspirin enteric-coated tablets(1 528 cases, 53.48%). The traditional Chinese medicine with the highest use frequency in combination with Danshen Chuanxiongqin Injection was Xingnaojing Injection, with a total of 378 cases, accounting for 13.23%. Among them, the most commonly used Western drugs combined with Danshen Chuanxiongqin Injection were anticoagulant thrombolytic and antiplatelet drugs, with a usage rate as high as 83.48%. In order to further explore the drug combination rules of Danshen Chuanxiongqin Injection, the association analysis of drug combination in patients of cerebral infarction treated with Danshen Chuanxiongqin Injection was carried out. In clinical combination of two Western drugs, Atorvastatin Calcium Capsules+Cerebral Proteolytic Injection were the most common combination, with a support of 27.10%. In clinical combination with 3 Western drugs, Clopidogrel Bisulfate Tablets+Atorvastatin Calcium Capsules+Cerebral Proteolytic Injection were most commonly used, with a support of 15.90%. The results showed that the patients of cerebral infarction treated with Danshen Chuanxiongqin Injection were mainly elderly males, and often complicated with hypertension, coronary heart disease, diabetes and other basic diseases. The clinical application of Danshen Chuanxiongqin Injection was principally in line with the guidelines. In the treatment of cerebral infarction, it was often combined with Western medicine anticoagulant thrombolysis, antiplatelet drugs, traditional Chinese medicine blood-activating and stasis-dissolving prescription and other drugs with similar pharmacological effects, with an auxiliary therapeutic effect on patients of cerebral infarction complicated with other diseases, and can provide guidance for clinical medication.

ABSTRACT

OBJECTIVE@#To choose the disease-causing gene in a Chinese pedigree with ankylosing spondylitis (AS) by whole-exome sequencing (WES), and provide theory basis for mechanism of disease.@*METHODS@#Clinical data of AS pedigree were collected, including 2 males, the age were 48 and 18 years old, the course of disease were 23 and 4 years. Whole blood genomic DNA of AS was extracted to perform whole exome sequencing, the results were compared with human databases, common variations which had been reported were wiped out, then non synonymous single nucleotide variants(SNVs) from the family members were combined, and candidate genes was selected initially.@*RESULTS@#Totally 80 G data was obtained from AS family with high quality.By comparing results between patient and normal subject, and filtering with number of biological database, the result showed heterozygous mutation of JAK2 gene 12 exon c.1709 A>G (p.Tyr570Cys) may be the potential disease-causing gene. The variant c.1151T>C of MUC3A gene may be one of the causes of intestinal symptoms in the family members.@*CONCLUSION@#It is feasible to find t candidate gene mutations of AS by Exon sequencing. The mutation c.1709 A>G in gene JAK2 identified by whole exome sequencing might be the pathogenic mutation in this AS pedigree.

ABSTRACT

Cinnamomum cassis is one of the commonly used traditional Chinese medicines in China. Its genuine producing areas distribute in Guangdong and Guangxi provinces. As an important edible herb and export variety of China, the quality control and internationalization of quality standards of C. cassis is extremely significant. In the recent years, with the development of the cinnamon industry, relevant academic research and the upgrade of the international standards, it is necessary to summarize the quality-related progress of C. cassis. In the present review, the germplasm resources, specific quality marker(Q-marker) and quality standards of C. cassis were summarized on the basis of published research during the last 10 years.

ABSTRACT

Guizhi Fuling Capsules is a new-type traditional Chinese medicine preparation made by modern process method. It was widely used to treat uterine fibroids, pelvic inflammation, dysmenorrhea, endometriosis, mammary gland hyperplasia and other gynecological diseases. Under the combination of disease and syndrome, the diagnosis and treatment model of "Yizheng Tongbing, Yibing Tongzhi" with Chinese patent medicine has been widely used in clinical practice. Meanwhile, the effectiveness and safety have been given more and more attention. Based on the effectiveness of Guizhi Fuling Capsules, this paper preliminarily summarized the dominant diseases in randomized controlled trials and systematic reviews of Guizhi Fuling Capsules. On the basis of the basic theory of traditional Chinese medicine and modern pharmacological mechanism, the clinical efficacy and mechanism of Guizhi Fuling Capsules were explored. Finally, according to the traditional Chinese medicine theory of "Yizheng Tongbing, Yibing Tongzhi", all the clinical evidences were integrated to form an integrated evidence chain, so as to provide guidance for the safe and rational use of Guizhi Fuling Capsules.

ABSTRACT

To understand the family sex education for young children in rural areas of Sichuan province and analyze the influencing factors. A multi-stage random sampling method was used to select 2246 parents of kindergarten children from rural areas in Sichuan province for a questionnaire-based survey.The Chi-square test and Logistic regression model were used for data analysis. It was found 1132(52.33%)parents had implemented family sex education for young children and 1031(47.67%)had not.Young children having asked sex-related questions(=1.536,95%=1.257-1.878),parents thinking that early childhood sex education is necessary(=3.691,95%=2.029-6.717),and parents having the intention to know early childhood sex education(=1.700,95%=1.274-2.269),and kindergarten having implemented early childhood sex education(=3.316,95%=2.515-4.372)were promoting factors for parents to conduct early childhood sex education,whereas a total annual household income at the middle level(=0.664,95%=0.456-0.968)was a hindering factor for parents to conduct early childhood sex education. Parents of young children in rural areas of Sichuan province have poor awareness of sex education,and the proportion of parents who have never conducted sex education for children is high.The total annual income of the family,whether the children have asked about sex-related questions,parents' attitude towards early childhood sex education,and whether the kindergarten has conducted the early childhood sex education are important factors that influence the level of children's family sex education.

ABSTRACT

Objective To evaluate the effects of Cu2+ and Cd2+ at different concentrations on superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activity in Oncomelania hupensis. Methods Cu2+- and Cd2+-containing solutions were prepared at 7 concentrations, and O. hupensis snails were exposed to the solutions for 24 h, of 15 snails in each concentration. Then, the snail body was collected following removal of the snail shell and homogenated, and the SOD, CAT and POS activities were detected in the supernatants. Results With the increase of the Cu2+ concentration, the SOD activity appeared a rise followed by a reduction in O. hupensis snails, and the CTA activity appeared a decline-rise-decline tendency, while the POD activity showed a tendency towards rise followed by decline. With the increase of the Cd2+ concentration, the SOD activity appeared a rise followed by a reduction in O. hupensis snails, and the CTA activity appeared a decline- rise- decline tendency, while the POD activity showed a decline-rise-decline tendency. Conclusion Exposure to Cu2+ and Cd2+ at high concentrations results in a decline in the activity of SOD, CAT and POD in O. hupensis at the same time.
