RESUMEN
@#Objective To investigate the relationship between atherosclerotic plaque characteristics and clinical symptoms in patients with unilateral moderate-to-severe stenosis of the extracranial segment of the internal carotid artery. Methods We included a total of 151 patients who underwent carotid endarterectomy for unilateral moderate-to-severe carotid stenosis [confirmed by carotid Doppler ultrasonography(CDU) and computed tomography angiography] at the Department of Neurosurgery of the First Affiliated Hospital of Soochow University. They were divided into symptomatic group and asymptomatic group according to clinical manifestations. The two groups were examined by CDU for the characteristics of carotid artery plaques(fibrous cap integrity,ulcerative plaques,plaque calcification,etc.) and the degree of vascular stenosis. Transcranial Doppler ultrasonography was performed to record the hemodynamic parameters(Vm,Vs,Vd,and PI) of bilateral middle cerebral arteries(MCA). Computed tomography perfusion imaging(CTP) was performed to record the parameters(CBF,CBV,MTT,and TTP) of bilateral basal ganglia and temporal lobes. The two groups were compared for carotid plaque characteristics and the degree of stenosis using the chi-square test,and for the differences in the hemodynamic parameters of MCA between the unaffected and affected sides and the CTP parameters of the basal ganglia and temporal lobe on the affected side using the independent samples t test and the Mann-Whitney U test. Results The symptomatic group was significantly older at the age of onset than the asymptomatic group(P<0.05). The incidence rates of ulcerative plaques and plaque surface calcification were significantly higher in the symptomatic patients with moderate/severe carotid stenosis than in the asymptomatic groups(P<0.05). The differences in Vm,Vs,and Vd of MCA between the unaffected and affected sides were significantly larger in the symptomatic moderate/severe stenosis groups than in the asymptomatic moderate/severe stenosis groups(P<0.05). There were significant differences in CBF,MTT,and TTP of the basal ganglia and temporal lobe on the affected side between severe stenosis groups(P<0.05),but those CTP parameters showed no significant differences between moderate stenosis groups(P>0.05). Conclusion Severe carotid artery stenosis can cause intracranial hypoperfusion,and moderate stenosis with unstable plaques can also produce clinical symptoms. It is of great clinical significance to evaluate carotid plaque characteristics and the degree of stenosis for individualized diagnosis and treatment.

Objective:To investigate the effect of helicobacter pylori (HP) infection and eradication treatment on small intestinal bacterial overgrowth (SIBO) in children.Methods:A prospective case-control study was conducted to select 68 children with symptoms of abdominal distension, abdominal pain, diarrhea and suspected digestive system diseases admitted to the Affiliated Hospital of Xuzhou Medical University from June 2021 to June 2022. They were divided into HP negative group and HP positive group according to HP infection. HP positive group received triple standardized HP eradication treatment, 14 days as a course of treatment. The baseline SIBO positive rate and gastrointestinal symptom rating scale (GSRS) score of the two groups were compared. The HP positive group was followed up for 4 and 12 weeks after drug withdrawal for quantitative assessment of gastrointestinal symptoms and LHBT. The SIBO positive rate, GSRS score of the two groups and the change of SIBO positive rate and GSRS score of the HP positive group before and after treatment were compared. The measurement data with normal distribution were expressed, and independent sample t-test was used for comparison between the two groups. M( Q1, Q3) was used to represent the measurement data of non normal distribution, and Mann Whitney U test was used to compare the two groups; Friedman test was used for comparison between multiple time points, and Nemenyi test was used for pairwise comparison. Four grid table or paired χ 2 test was used to compare the counting data between groups. Results:The positive rate of SIBO in HP negative group was lower than that in HP positive group (36.1% (13/36) vs 62.5% (20/32)), the difference was statistically significant (χ 2=4.72, P=0.030). Four weeks after drug withdrawal, the SIBO positive rate in HP positive group was higher than that before treatment (87.5% (28/32) vs 62.5% (20/32)), and 12 weeks after drug withdrawal was lower than that before treatment (21.9% (7/32) vs 62.5% (20/32)), with statistically significant differences (χ 2=8.00, P=0.008; χ 2=13.00, P<0.001). There was no statistically significant difference in GSRS score between HP negative group and HP positive group ( P=0.098). The clinical symptoms of 32 children in HP positive group were improved 4 and 12 weeks after HP eradication was stopped. GSRS scores were lower than those before treatment (8.0 (6.0, 12.8), 7.0 (5.0, 9.0) points vs 15.0 (12.0, 19.0) points) , and the differences were statistically significant ( Z values were -3.91, -4.68, respectively; all P<0.001). Conclusions:HP infection can increase the positive rate of SIBO in children with suspected digestive system diseases. The standardized triple HP eradication therapy may further aggravate the overgrowth of intestinal bacteria while treating HP infection, but this effect can be eliminated after 12 weeks of treatment.

Objective To investigate the efficacy of different courses of saccharomyces boulardii powder combined with triple therapy in eradicating helicobacter pylori(Hp)in children.Methods A total of 135 children with Hp-related gastritis who received initial treatment in the Department of Pediatrics,Affiliated Hospital of Xuzhou Medical University from October 2021 to June 2022 were selected and divided into three groups according to random number table method:group A,group B and group C,with 45 cases in each group.Group A:triple therapy(omeprazole + clarithromycin + amoxicillin)for 14 days;group B and group C:on the basis of triple therapy,saccharomyces boulardii powder was added from the first day of treatment for 2 weeks and 4 weeks,respectively.The adverse reactions during treatment were recorded,the levels of serum pepsinogen Ⅰ(PGⅠ)and pepsinogen Ⅱ(PGⅡ),clinical efficacy and Hp eradica-tion rate were observed 4 weeks after the end of treatment.Results The levels of serum PGⅠ and PGⅡ in the three groups after treat-ment were significantly lower than those before treatment(P<0.05),the levels of serum PGⅠ and PGⅡ in group B and group C after treatment were lower than those in group A(P<0.05),and the levels of serum PGⅠ and PGⅡ in group B were lower than those in group C after treatment(P<0.05).The clinical effective rates of group B(93.0%)and group C(90.4%)were higher than those of group A(62.5%)(P<0.05).The clinical effective rate of group B was higher than that of group C(P>0.05).The Hp eradication rate of group B and group C was significantly higher than that of group A(P<0.05),and the Hp eradication rate of group B was higher than that of group C(P>0.05).The incidence of diarrhea and loss of appetite in group B and group C were lower than those in group A(P<0.05);the incidence of diarrhea and loss of appetite in group B was lower than that in group C(P<0.05).There was no signifi-cant difference in the incidence of abdominal pain,nausea and vomiting among the three groups(P>0.05).Conclusion Saccharomy-ces boulardii decoction combined with triple therapy for 2 or 4 weeks can effectively regulate PG level,improve the eradication rate of Hp,and reduce the incidence of adverse reactions.It is suggested that 2 weeks is the best course of treatment.
RESUMEN
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.
