ABSTRACT
Objective@#To analyze the emotional and behavioral problems and associated factors of the only and non only child, and to provide some clues for further monitoring and intervention of psychological and behavioral development among preschool children.@*Methods@#Using a convenience sampling method, a total of 45 065 children enrolled in 153 kindergartens in 23 districts and counties of Chengdu were selected from May to June 2021 to investigate demographic characteristics and children s psycho behavioral development through online questionnaires filled out by their guardians. The Chi square tests were used to analyze whether the differences in abnormality rates of each dimension were statistically significant between the only and non only children. The emotional and behavioral problems of only children and non only children were analyzed by propensity score measurement.@*Results@#The detection rate of abnormal emotional behavior problems in children was 6.10%, including 6.34% in the only child group and 5.84 % in the non only child group. After matching, total difficulty score, and scores of emotional symptoms, conduct problems, hyperactive attention deficit, peer interaction, and social behavior differed between the only child group and the non only child group ( t =9.91, 8.97, 3.91, 15.57, -5.46, 4.08, P <0.01).@*Conclusion@#In terms of the total score of difficulties, emotional symptoms, moral problems, and hyperactivity attention defects, the non only child is better than the only child，but the opposite is true in terms of peer interaction and social behavior. Mental health conditions among the only child should be paid more attention. Whether or not the only child should be taken as an important consideration for preschool children s mental health care.
ABSTRACT
Objective@#To explore the relationship between fruit intake and the risk of overweight with obesity in children, so as to provide references for the prevention of childhood obesity.@*Methods@#From September to November 2014, a stratified cluster sampling method was used to select 6 369 children aged 6-12 from two elementary schools of a country in rural Chongqing for physical examinations and questionnaire surveys, and 1 814 children in grades 1-2 at baseline were followed up from March to May 2019. The relationship between fruit intake and the prevalence of overweight and obesity was analyzed.@*Results@#According to the percentile of fruit intake, the 6 369 children at baseline were assigned to three groups: Q 1 (< P 33.3 , fruit intake <100 g/d), Q 2 ( P 33.3 - P 66.7 , fruit intake:100-214.3 g/d), and Q 3 (> P 66.7 , fruit intake >214.3 g/d). For the baseline survey results, children in the Q 2 group had a lower weight and Body Mass Index (BMI) ( P <0.05); the prevalence of overweight and obesity among children in the Q 1 group was the highest (32.03%), and the prevalence of overweight and obesity among boys in the Q 2 group was the lowest (31.94%) after gender stratification ( P <0.05). The follow up survey results showed no significant differences between the three groups in terms of changes in height, weight, and BMI ( P >0.05); but the prevalence of obesity among youth in the Q 2 group was the lowest (5.07%, P <0.05). Compared with youth in the Q 2 group, the risk of obesity was higher among those in the Q 1 group at baseline survey ( OR=1.41, 95%CI=1.10-1.81, P <0.05), and was higher among those in the Q 3 group at follow up survey ( RR= 1.83, 95%CI=1.21-2.75, P <0.05).@*Conclusion@#Deviating from moderate fruit intake may increase the likelihood of overweight and obesity in children, and it is recommended that children are encouraged to consume fruits as part of a well balanced diet to prevent the occurrence of obesity.
ABSTRACT
Abstract This study aimed to compare the effects of diet and exercise of different intensities on antioxidant function, aortic endothelial cell function and serum lipids in NAFLD (nonalcoholic fatty liver disease) rats. Fifty Sprague-Dawley (SD) rats (180-220g) were randomly divided into two experimental groups and fed either a standard rodent chow diet (CON; n=10) or a high-fat diet (HFD; n=40). After 16 weeks, the animals that received the HFD were randomly separated into a high-fat control group (HFC; n=10) or three exercise training groups: HFD and low-intensity exercise (LE; n=10), HFD and moderate-intensity exercise (ME; n=10), and HFD and incremental intensity exercise (IE; n=10). These experimental rats keep sedentary or trained for the next six weeks. A detection kit was used to detect nitric oxide synthase (NOs), nitric oxide (NO), malondialdehyde (MDA) and other markers of aortic oxidative stress. The expression levels of endothelial nitric oxide synthase (e-NOS) and endothelin-1 (ET-1) were detected by immunohistochemistry. TC, TG, and other lipid metabolism parameters were detected by an automatic analyzer. Exercise with different intensities could improve lipid metabolism, enhance antioxidant function, reduce MDA (P<0.01), increase NO (P<0.01), and improve the expression of e-NOS and ET-1 (P<0.01) protein levels in NAFLD rats. Decreased blood lipids were exhibited in all exercise groups. Notably, the moderate-intensity exercise demonstrated more effect on increasing glutathione (GSH) contents (P<0.01) and decreased the expression of ET-1 protein levels (P<0.01). The results showed that exercise at different intensities improved lipid metabolism and enhanced anti-oxidation function. Moderate exercise could improve the function of aortic endothelial cells.
Resumen Este estudio tuvo como objetivo comparar los efectos de la dieta y el ejercicio a diferentes intensidades sobre la función antioxidante, la función de las células endoteliales aórticas y los lípidos séricos en ratas NAFLD (con enfermedad del hígado graso no alcohólico) y alimentados con una dieta estándar para roedores (CON; n = 10) o con una dieta alta en grasas (HFD; n = 40). Después de 16 semanas, los animales que recibieron HFD se separaron aleatoriamente en un grupo de control alto en grasas (HFC; n=10) o tres grupos de entrenamiento físico: HFD y ejercicio de baja intensidad (LE; n=10), HFD y ejercicio de intensidad moderada (ME; n=10), y HFD y ejercicio de intensidad incremental (IE; n=10). Estas ratas experimentales se mantuvieron sedentarias o entrenadas durante las próximas seis semanas. Se utilizó un kit de detección para determinar óxido nítrico sintetasa (NO), óxido nítrico (NO), malondialdehído (MDA) y otros marcadores de estrés oxidativo aórtico. Los niveles de expresión de la óxido nítrico sintetasa endotelial (e-NOS) y endotelina-1 (ET-1) se detectaron mediante inmunohistoquímica. El analizador automático detectó TC, TG y otros parámetros del metabolismo de los lípidos. El ejercicio con diferente intensidad mejoró el metabolismo de los lípidos, mejoró la función antioxidante, redujo la MDA (P <0,01), aumentó el NO (P <0,01) y mejoró la expresión de los niveles de proteína e-NOS y ET-1 (P <0,01) en ratas NAFLD. Se observó una disminución de los lípidos en sangre en todos los grupos de ejercicio. En particular, el ejercicio de intensidad moderada demostró un mayor efecto en el aumento del contenido de glutatión (GSH) (P<0,01) y disminuyó la expresión de los niveles de proteína ET-1 (P<0,01). Los resultados mostraron que el ejercicio a diferentes intensidades mejoró el metabolismo de los lípidos y mejoró función antioxidante. El ejercicio moderado podría mejorar la función de las células endoteliales aórticas.
ABSTRACT
Objective@#To explore whether psychological stress in early and mid puberty is predictive of adolescent healthrisk behaviors.@*Methods@#In April 2018, a total of 1 046 primary and secondary school students from grade 5 to 8 were recruited through purposive sampling. The basic information and psychological stress of the respondents were collected by questionnaire and physical examination. In addition, self reports of health risk behaviors were collected in October 2018. Logistic multiple regression analysis was used to analyze the relationship between psychological stress and health risk behaviors of adolescents.@*Results@#The reported health risk behaviors of the surveyed adolescents ranking from high to low were unreasonable physical activity (62.05%), food preferences (24.76%), fighting (21.03%), suicidal ideation (17.02%), ideation of running away from home (9.85%), low mood (8.80%), smoking (4.21%), drinking (3.73%), gambling (3.63%) and internet addiction (3.06%). Logistic multiple regression analysis showed that the high level of psychological stress was a risk factor for fighting ( OR =1.02, 95% CI =1.01-1.03), suicidal ideation ( OR =1.02, 95% CI =1.01-1.03), low mood ( OR =1.02, 95% CI =1.01-1.03), ideation of running away from home ( OR =1.02, 95% CI =1.01-1.03), unreasonable physical activity ( OR =1.01, 95% CI =1.00-1.02), smoking ( OR =1.02, 95% CI = 1.00-1.03), internet addiction ( OR =1.02, 95% CI =1.00-1.03), food preferences ( OR =1.01, 95% CI = 1.00-1.02) and gambling ( OR =1.02, 95% CI =1.01-1.04)( P <0.05).@*Conclusion@#Unreasonable physical activity and food preferences are most common health risk behaviors among adolescents. Psychological stress during early to middle puberty is predictive of adolescent health risk behaviors.

ABSTRACT
Objective@#To explore the status of depressive symptoms among adolescents in different pubertal stages in a district of Chongqing.@*Methods@#A self designed questionnaire and Children s Depression Inventory were administered among 1 001 students in a district of Chongqing. Score and associated factors of depressive symptoms of adolescents through descriptive statistical analysis, Chi square test, analysis of variance and Logistic regression analysis.@*Results@#The detection rate of depressive symptoms among adolescents in a district of Chongqing was 17.3%, and the total score of depression scale was (12.02±6.72). There were statistically significant differences in the inefficiency subscale score of boys across stages of genital, pubic hair, armpit hair and beard, and whether the first spermatorrhea has occurred( t/F =7.08，5.46，5.18，4.21，5.84， P <0.05), while significant differences were found in the anhedonia and inefficiency subscales scores among girls across different stages of breast, pubic hair and armpit hair, and whether menarche has occurred( t/F =19.43，4.92，3.98，7.35， P <0.05). Multivariate Logistic regression analysis showed that the absence of first spermatorrhea and menarche were associated with lower prevalence of depressive symptoms in boys and girls ( OR=0.60, 95%CI=0.36-0.98; OR=0.46, 95%CI =0.22-1.00), while pubic hair development was associated with higher prevalence of depressive symptoms in girls ( OR=9.58, 95%CI =1.28- 71.71 ).@*Conclusion@#The detection rate of depressive symptoms among adolescents is relatively low. Boys who have had the first spermatorrhea, and girls with advanced pubic hair development or have had menarche are more likely to suffer from depressive symptoms.
ABSTRACT
Objective@#To explore the influence of parental company before and after having second child on the emotional and behavioral problems of preschool firstborn children, and to provide a reference for emotional problems prevention of firstborn children.@*Methods@#Questionnaire survey was conducted among mothers of firstborn children who met the inclusion and exclusion criteria from two Grade A hospitals in Chongqing from March to December 2019. The average age of 845 firstborn children was (3.56±1.24) years old. The chi square test was used to compare the general characteristics and parent company of boys and girls. Rank sum test was used to compare the differences of emotional and behavioral problems of firstborn children with different parents company. Multiple linear regression models were used to compare the differences of internalizing, externalizing and total problems in firstborn children with different parents company.@*Results@#After having the second child, parents spent less time with their firstborn children, among which the decrease of the accompanying time of the mother and the total accompanying time of the parents were statistically significant( Z =3.76, 2.86, P <0.05). The scores of internalizing problem were higher when the mother s company time decreased ( B=1.18, 95%CI = 0.01 -2.36) and the parents total company time decreased( B=1.41, 95%CI =0.33-2.48). The scores of the externalizing problem ( B=1.25, 95%CI =0.10-2.39) and the total problem ( B=4.31, 95%CI =1.05-7.57) with the decrease of parents total company time were higher.@*Conclusion@#Parent company has an important influence on the emotional and behavioral problems of firstborn children. Firstborn children whose parents accompanying time decreases after having second children scored higher on emotional and behavioral problems.
ABSTRACT
Objective@#To compare the emotional and behavioral characteristics of preschool firstborn children across the transition to siblinghood with the only children in a district of Chongqing.@*Methods@#Data were derived from a cohort study on firstborn children transition to siblinghood. Totally 882 firstborn children (3.58±1.25) years old and 329 only children (3.98±1.02) years old were recruited from two hospitals and 19 kindergartens in a district of Chongqing, respectively. Their mothers filled out the parental version of Child Behavior Checklist (CBCL) and self designed questionnaire.@*Results@#The overall scores of emotional and behavioral problems of firstborn children and only children were (25.17±18.82) and (31.75±18.64). The results of rank sum test showed that the scores of the firstborn children in all dimensions, internalizing and externalizing behavior problems and overall emotional and behavioral problems were lower than those of the only children ( P <0.05). Chi square test results showed that the detection rates of internalizing, externalizing and overall emotional behavior problems in only children(12.77%, 13.07%, 14.59%) were higher than those in firstborn children(8.28%, 8.28%,8.16%) ( χ 2=5.62, 6.36, 11.09, P <0.05). Multiple linear regression showed that after adjusting for age, gender, family economic pressure, temperament type of children, family atmosphere and family type, the scores of internalizing problems, externalizing problems and overall problems of the only children were still higher than those of the firstborn children ( B =1.54, 2.32, 6.81, P <0.05).@*Conclusion@#The firstborn children across the transition to siblinghood show less emotional and behavioral problems than the only children, and the scores and detection rates of all types of emotional and behavioral problems of the firstborn children are lower than those of the only children.
ABSTRACT
Objective@#To explore the relationship between the emotional and behavioral problems and family relations of firstborn children from an urban area of Chongqing during the role transition period, to provide a scientific basis for creating a good family relationship and to reduce the occurrence of children s emotional behavior problems.@*Methods@#Totally 1 359 mothers of children in the role transition period were recruited from obstetric clinics at two Grade A hospitals in Chongqing, and mothers with informed consent using self designed questionnaire and parental version of the Child Behavior Checklist (CBCL). It was analyzed the association between family relationships and the emotional/behavioral problems of firstborn children of different ages. SPSS statistical software (version 20) was used for the descriptive statistical analysis, chi square test, and multiple linear regression analysis.@*Results@#The parental relationship (56.6%), mother child relationship (80.4%) and father child relationship (64.9%) of most firstborn children was good, and 61.7% of families enjoyed a harmonious atmosphere. For the age groups 1.5-5 years and 6-13 years, the respective CBCL total scores were (18.22±13.63) and (24.20±17.52), and the detection rates were 10.7% and 10.5%, respectively. The results of the multiple linear regression analysis showed that, for both age groups, firstborn children who had good parental relationships, good mother child relationships, good father child relationships, and a harmonious family atmosphere exhibited fewer internalizing, externalizing and overall emotional behavior problems ( P <0.05).@*Conclusion@#The total detection rate of emotional and behavioral problems among firstborn children in the role transition period, which is low. Good parental relationships, good parent child relationships, and a harmonious family atmosphere are protective factors against emotional and behavioral disorders in firstborn children during the role transition period.
ABSTRACT
Objective@#This study systematically reviewed the findings of studies on the factors influencing emotional and behavioral problems among firstborn children in transition to siblinghood, to provide a theoretical basis for the study of emotional behavior in firstborn children during role transition.@*Methods@#CBM, VIP, CNKI, WanFang Data, PubMed, Web of Science, OVID and EBSCO were electronically searched to collect studies on the relevant factors influencing the emotional and behavioral characteristics of firstborn children in transition to siblinghood (TTS) from inception to March 3rd, 2021. Literature screening and data extraction were conducted by two independent authors to evaluate the risk of bias in the included studies. The results of the included studies were summarized by qualitative analysis.@*Results@#A total of nine studies were included, comprising four prospective cohort studies and five cross sectional studies. Systematic evaluation results indicated three main types of factor associated with behavioral problems among firstborn children:factors of firstborn children (gender, age and temperament), family factors (parents upbringing, family relationships, family environment, social economy, maternal behavior and whether firstborn children knew that the second children would arrive), and social factors (relationships between teachers and students, peer relationships and life changes). The main factors affecting emotions were their own factors (age and self acceptance). Negative temperament in firstborn children, negative parenting styles, negative family relationships and family environments, prohibited behaviors among mothers, whether the firstborn children were informed of the arrival of the second children during pregnancy, poor relationships between teachers and students, peer relationships and life changes may increase the risk of emotional and behavioral problems among firstborn children. Whether other factors might have affected the results of the study is unclear.@*Conclusion@#Important factors influencing firstborn children s emotions and behaviors during TTS, must be confirmed through a high quality prospective cohort study. Intervention studies may be appropriate to verify the results and provide an empirical basis for behavioral interventions in firstborn children with different emotional problems.
ABSTRACT
Abstract@#With the amendment of China s family planning, the number of firstborn children has increased gradually, thus resulting in only children transitioning to non only children. The emotional changes and the mental and behavioral problems faced by these firstborn children have begun to receive extensive attention among scholars and society. Childhood emotional and behavioral problems can affect later adult life, such as by increasing the risk of maladjustment and peer rejection in adulthood. Research using innovative study designs is crucial to examine firstborn children s emotional and behavioral problems, and the factors influencing these problems. Empirical research on interventions will be highly important to ensure a healthy transition of firstborn children from only children to non only children.
ABSTRACT
@#Objective To analyze the risk factors of anastomotic leakage after esophagectomy. Methods The clinical data of 1 328 patients with esophageal cancer, who underwent esophagectomy in the First Affiliated Hospital of Henan University of Science and Technology from January 2010 to December 2016, were retrospectively analyzed. There were 726 males and 602 females, at an average age of 67.2±14.1 years. According to whether there was anastomotic leakage after operation, patients were divided into two groups: an anastomotic leakage group (167 patients) and a non-anastomotic leakage group (1 161 patients). Univariate and multivariate logistic regression analysis was used to identify related risk factors of anastomotic leakage after operation. Results The incidence of postoperative anastomotic leakage was 12.6% (167/1 328). Univariate analysis showed that body mass index, arrhythmia, chronic obstructive pulmonary disease (COPD), diabetes, preoperative albumin level, preoperative chemotherapy and chemoradiotherapy, lesion location, anastomosis types and postoperative pulmonary infection were associated with statistically significant increase in risk of cervical anastomotic leakage (P<0.05). Logistic regression analysis showed that preoperative COPD, lesion location and postoperative pulmonary infection were independent risk factors of cervical anastomotic leakage after esophagectomy (P<0.05). Conclusion The occurrence of cervical anastomotic leakage after esophageal cancer is related to many factors. The preoperative COPD, the lesion location and the postoperative pulmonary infection are independent high risk factors. Paying attention to these factors and doing perioperative management can effectively reduce the occurrence of anastomotic leakage.
ABSTRACT
Objective@#Longitudinal data were used in this study to examine the predictive effects of psychological stress in early puberty on subsequent anxiety and depression symptoms.@*Methods@#Objects from a puberty cohort of 998 children from 4 primary schools in Chongqing were included. Psychological stress was measured during their early puberty, and anxiety and depression were followed up after 4 years. Multiple linear regression was used to analyze the influence of psychological stress on anxiety and depression level in their middle puberty.@*Results@#The average score of psychological stress during early puberty was (34.79±24.78), and scores of anxiety and depression were (11.20±10.89) and (12.06±6.69), respectively, with detection rates of 14.03% and 15.63%. Girls had higher anxiety and depression scores than boys(F=51.58,5.48，P<0.05). The depression scores of children with different parents’ educational levelsand perceived parental relationship were different(F=6.74, 7.38, 10.49, P<0.05). The results of multiple linear regression showed that girls(β=4.38), higher psychological stress(β=0.13), older age (β=0.89) were risk factors for higher anxiety level. Children with higher psychological stress(β=0.05), older age(β=0.57), perceived worse parents’ relationship(β=1.19), lower maternal education (β=-1.00) had higher depression scores(P<0.05).@*Conclusion@#The psychological stress level, and age during early puberty had a positive predictive effect on anxiety and depression after 4 years. Simultaneously, girls were more prone to anxiety, and poor parental relationship and low maternal literacy were risk factors for children’s depression.
ABSTRACT
Objective@#To analyze the characteristics of puberty growth of boys and to explore the relationship between puberty growth and sexual development of boys.@*Methods@#Pubertal development of boys from grade 1 to grade 4 in Jiulongpo district of Chongqing was followed up once every six months. The data of height, weight, BMI, the age of first ejaculation and testicular development of boys from baseline to follow-up every 6 months for 5 years were analyzed. Based on peak height velocity (PHV), the average level of PHV and age at peak height velocity(PHA) were analyzed. ANOVA was used to compare the height growth rate of boys in different age groups before and after the first ejaculation. Kendall rank correlation was used to analyze the relationship between different stages of testicular development and BMI.@*Results@#The mean age of PHA was (11.72±1.03) years in adolescent height speed cohort, and the mean age of first ejaculation was (12.45±0.98) years before and after the first ejaculation cohort. There was significant difference in the increment of height before and after one year of the age of first ejaculation (P<0.05), the younger the age of the first ejaculation, the greater increase of height in the following year. The height, weight, BMI of boys aged 11 to 14 years were positively correlated with testicular volume(P<0.05).@*Conclusion@#The height growth of boys reached its peak one year before the first ejaculation, and began to decrease after first ejaculation, and the age of the first ejaculation of boys was negatively correlated with the increment of height in the following year, while the testicular development of boys was positively correlated with height, weight and BMI.
ABSTRACT
Objective@#To explore the association between different family factors and children’s puberty timing, and to provide a reference for further research on puberty development of children.@*Methods@#A prospective cohort study was conducted on a total of 1 237 children in one district, Chongqing, using targeted sampling. Cox regression was used to analyze the association between family factors and the puberty timing of children.@*Results@#The results of univariate analysis showed that baseline age and BMI were risk factors of early puberty timing in boys and girls (P<0.01). Breast development (HR=1.27, 95%CI=1.04-1.54) was observed earlier in vaginal delivery than in cesarean section. Self-conscious family economic condition is good is the protective factor for the early timing of girl’s menstruation (HR=0.81, 95%CI=0.66-0.99), pubic hair development(HR=0.80, 95%CI=0.65-0.97) and the boy’s puberty development (Testicular development HR=0.69, 95%CI=0.58-0.83, first ejaculation HR=0.62, 95%CI=0.49-0.78, external genitalia development HR=0.70, 95%CI=0.56-0.87, pubic hair development HR=0.66, 95%CI=0.54-0.80). The left-behind boys later observed testicular development (HR=0.74, 95%CI=0.57-0.96), first ejaculation (HR=0.71, 95%CI=0.50-0.99) and pubic hair development (HR=0.68, 95%CI=0.51-0.91). Testicular development (HR=1.26, 95%CI=1.01-1.58) was observed earlier in boys who felt their parents were close (P<0.05). The results of multivariate analysis showed that the timing of pubic hair development was later in floating girls (HR=0.79, 95%CI=0.65-0.96), and family factors had nothing to do with the puberty timing in boys.@*Conclusion@#In the study, left behind children, self-perceived of parents relationship and family economic conditions are the influencing factors of children’s puberty timing. However, after adjusted for age and BMI, this association was mainly found in pubic hair of girls. The association between family factors and other pubertal development events still needs to be confirmed by further follow-up investigation.
ABSTRACT
@#[Abstract] Objective: To investigate the expression and clinical significance of CEAmRNAin peritoneal lavage fluid for patients with gastric cancer after radical surgery. Methods: The clinical data of 139 gastric cancer patients, who underwent peritoneal lavage CEA mRNA detection after radical resection in the Comprehensive Cancer Centre of Drum Tower Hospital from January 2013 to December 2017 were retrospectively analyzed. Routine post-operative follow-up was conducted in all patients. The expression of CEA mRNA in peritoneal lavage fluid after radical resection of 139 gastric cancer patients was detected by RT-PCR. Chi-square test analysis was used to study the relationship between the expression of CEA mRNA in peritoneal lavage fluid and basic clinical features, histopathological data, hematological indicators and the recurrence pattern of GC patients. Logistic univariate and multivariate regression analyses were used to screen the influential factors affecting CEA mRNA expression. Results: CEA mRNA was positive in 44 (31.7%) of 139 patients. Analysis showed that there was no significant correlation between CEA mRNA expression and sex, age, pathological grade, Lauren type, HER2, EGFR, VEGFR and Ki67 (all P>0.05), but there was significant correlation between CEA mRNA expression and pathological type, vascular invasion, local invasion depth, lymph node metastasis and clinical AJCC stage (all P<0.05). The peritoneal recurrence rate of patients with positive CEA mRNA expression was significantly higher than that of patients with negative expression (P=0.012). Logistic univariate regression analysis showed that signet ring cell carcinoma (P=0.04, HR=2.810， 95% CI: 1.050-7.520), T stage (P=0.016，HR=6.329, 95% CI: 1.417-28.264), N stage (P=0.022，HR=3.068，95% CI: 1.172-8.027), AJCC stage (P=0.016，HR= 3.971, 95% CI: 1.295-12.173), nerve invasion (P=0.002, HR=6.738, 95% CI: 1.995-22.757) and vascular invasion (P<0.001, HR= 16.36, 95% CI: 3.85-69.512) were risk factors for positive CEA mRNA expression in peritoneal lavage fluid of patients with gastric cancer. Logistic multivariate regression analysis showed that vascular invasion (P<0.001, HR=21.314，95% CI: 4.21-107.907) was an independent risk factor for positive CEAexpression in peritoneal lavage fluid of gastric cancer patients. Conclusion: Gastric cancer patients with positive CEA mRNA in peritoneal lavage fluid have higher risk of peritoneal recurrence or metastasis and poorer prognosis. So, more aggressive anti-tumor treatments including local abdominal cavity treatment should be considered.
ABSTRACT
Objective To discuss how to preven wrong absorption of pancreatic pseudocyst using guided transmural drainage under endoscopic ultrasonography.Methods Retrospectively analyzed the clinical data of patients with pancreatic pseudocysts underwent operations of Endoscopic ultrasonography guided transmural drainage.Results 16 cases of pancreatic pseudocysts were finished with guided transmural drainage under endoscopic ultrasonography using needling to place bypass grafting with successful rate 100.0% of guided transmural drainage by needling. After needling, 2 cased happened regurgitation which led to wrongly absorbed, rate of occurrence is 12.5%. Generally, pancreatic pseudocysts of 16 cases disappeared completely with cure rate 100.0%. From above, stents were pulled out by endoscope in 3 cases while stents were removed voluntarily in another 13 cases.Conclusion Dorsal elevated position, detailed operation and esophageal annular tubes can effectively prevent wrong absorption of guided transmural drainage under endoscopic ultrasonography of pancreatic pseudocysts.
ABSTRACT
Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.
ABSTRACT
<p><b>OBJECTIVE</b>To summarize the clinical features and therapeutic approach of systemic lupus erythematosus (SLE) complicated by transverse myelitis (TM).</p><p><b>METHODS</b>The clinical characteristics, laboratory examinations, treatment and prognosis of 6 SLE cases with TM were retrospectively analyzed with review of the literatures.</p><p><b>RESULTS</b>The 6 patients consisted of 5 females and 1 male aged 14 to 36 years (mean 23 years). The mean duration from symptom onset of SLE to TM was 8 months (1 to 13 months). All the patients had lower limb hypodynamia, and 3 of them developed upper limb hypodynamia. MRI scanning of the spine identified lesions in the cervical spinal cord in 2 cases, thoracic lesions in 3 cases, and multiple involvement of the cervical, thoracic and lumbar cord in 1 case. Examination of the cerebrospinal fluid yielded no specific findings except for leukocytosis in 1 case and hypoglycemia in another. Five cases were treated with high-dose MP+CTX, and the other case was treated with MP (80 mg/day)+CTX. Five patients responded favorably to the treatment, while the other showed no obvious improvement.</p><p><b>CONCLUSION</b>TM is a rare complication of SLE affecting mostly young patients and occurring in the early stage of the disease. Early diagnosis and aggressive treatment might improve the prognosis.</p>
