To analyze and explore the relationship between lactase activity and the structure of intestinal flora in infants under 1 year old. Method: Our hospital selected 60 infants and young children in the Haizhu Maternity and Child Health Hospital from August 2019 to September 2020 as the research objects. The infants in the experimental group were diagnosed as lactose intolerant infants, the control group were normal infants, and the experimental group and control group had 30 cases each. The relationship between lactase activity and intestinal flora structure. Result: The experimental group had fewer beneficial bacteria in the intestinal tract than the control group, but improved lactase activity by correcting the structure of the intestinal flora and alleviating symptoms of lactose intolerance. Conclusion: Infants and young children are prone to non-infectious diarrhea, and the causes are more complicated, but most of them are related to lactose intolerance. When infants and young children develop lactose intolerance, it is necessary to pay attention to the lack of beneficial bacteria in the intestinal tract. Targeted supplementation of probiotics (such as Lactobacillus reuteri, Clostridium butyricum, etc.) can correct the intestinal flora, improve lactase activity, and relieve symptoms of lactose intolerance.

The relationship between articulatory deficits and the development of syntax in children with severe articulation problems was investigated. Subjects in the experimental group were 30 normal elementary school children, enrolled in grades one through three, who had severe problems with articulation. Thirty normal children, free from any articulation errors, served as a control group. Children with defective articulation performed significantly less well in the areas of grammatical usage, and used shorter sentences. The relationship between phonological and syntactical errors is discussed, with implications for therapy.

Probiotics are a group of active microorganisms, which benefit the host by colonizing and changing the composition of host flora. It is of great significance to promote the development of human gastrointestinal nutrition and health by regulating the host mucosal and systemic immune function or regulating the balance of intestinal flora. The purpose of this study is to analyze the production activity of the enzyme, evaluate its biological characteristics and safety as a preventive drug, and provide reference for the research of enzyme production and compound enzyme preparation by probiotics. In this study, four groups of probiotics were set up: Clostridium butyricum experimental group, Lactobacillus plantarum experimental group, drinking water control group, and Bacillus licheniformis experimental group. In addition, a variety of complex enzyme experiments were set up to study the influence on the digestive tract and single factor experiment. The results showed that probiotics and compound enzyme preparations could significantly promote the intestinal digestibility. Under the effect of probiotics, the weight of the chicken was almost 1 Jin heavier than that of the control group, and the average digestibility was increased by 4.3%. The effect of the enzyme on digestibility is stronger than that of probiotics, but the final effect tends to be stable.

This study has explored the valence of sibship that may empower the self-esteem of children with asthma at the interpersonal, environmental control competence, emotionality management, and body-image levels. It has been assumed that the relationship between siblings may have a moderating effect on the negative impact that asthma has on child’s development. Seventy children suffering from chronic asthma have been involved: 40 children with siblings (experimental group) and 30 sibling-free children (control group). The children with asthma have exhibited higher levels of self-esteem in comparison with the sibling-free children. The results of the study, at the clinical significance level, highlight how meaningful could be the involvement of healthy siblings to support the development, and to ease the compliance of children suffering from asthma. The outcomes have confirmed the supportive valence of sibship for the self-esteem of the children with asthma.

The tremendous potential for autogenic feedback training in helping smokers to deal with their anxiety before and after termination as well as the need to make autogenic feedback training in a practical method for smoking termination prompted this study which: (1) investigated the changes in smoking activity in subjects who have had autogenic feedback training and those who have not; (2) investigated the relationship between the success in performing autogenic feedback and the success in smoking termination; and (3) investigated the effect of autogenic feedback training on anxiety reduction before and after smoking termination. Twenty-three subjects were randomly assigned to two groups. The first group received the autogenic feedback training initially while the second group served as the control. This control group became a second experimental group upon the completion of the first phase. The results of the study revealed that the autogenic feedback training was an effective adjunct to a smoking termination program. Eighty-one per cent reduction in smoking activity was found for the subjects that received the training.

The authors investigated the effect of the Peer Mediation with Young Children (PMYC) program on autonomy behavior of children trained to be mediators and on children mediated by trained peers. Previous findings have revealed higher levels of mediational teaching style and higher cognitive modifiability, a trait we believe to be associated with autonomy. The sample was composed of 40 pupils (20 pairs), randomly assigned to experimental or control groups (10 pairs each). The mediator in each pair was from third grade and the learner from first grade. The experimental children received instruction in the PMYC program, whereas the control children received general preparation for peer-assisted learning. Following the PMYC intervention, both groups participated in a peer-mediation condition. The interactions were videotaped and analyzed by the Observation of Autonomy Behavior Protocol. Experimental group children (mediators and learners) received significantly higher scores on autonomy behavior criteria than did the control group children.

Denaturing gradient gel electrophoresis (DGGE) analysis of 16S rRNA gene has been regarded as one of powerful tools for gaining insight into the bacterial diversity of intestinal system. In the present study, hyperlipidemia model was constructed in rat according to the tests of blood lipids. Fecal samples of rats were collected after 60d feeding, and DGGE was used to investigate the diversities of intestinal bacteria in the artificially-induced hyperlipidemia rats and normal rats. The results showed that two patterns had similarities, but there were also some different bacteria communities. Moreover, control group had much more bands than model group on gel, showing species in intestinal of model rats might be deduced by hyperlipidemia. It will be helpful to explore the relationship between hyperlipidemia and intestinal flora.

Abstract The studies involved gilts 6 weeks pre-partum allocated into the control and experimental groups. The experimental group received vitamin C at the dose of 2.5g/100 kg b.w./day. Faeces for analyses were collected for 3- and 6- week period of vitamin C dietary inclusion. The faecal material underwent quantitative and qualitative bacteriological evaluation. The count of Enterobacteriaceae was evaluated. The qualitative examination of these bacteria was made using the micro-plate method API 20E. Feed supplemented with vitamin C contributed to a statistically significant decline of the total bacterial count of Enterobacteriaceae in faeces. The qualitative bacterial analyses showed the presence of E. coli, Providecia sp., Proteus sp., and Salmonella sp. in the control and experimental groups. Enterobacter sp. was recovered only in the control group, while Lactobacillus sp. in the experimental group. The dietary administration of vitamin C significantly decreased the number of the studied bacterial species, except Salmonella rods. No statistically significant differences in the number of most blood morphotic elements following the 6- week supply of vitamin C were found; only the granulocyte count significantly increased, while lymphocyte numbers declined. Ascorbic acid inhibited the growth of pathogenic intestinal flora and reduced the pathogenic and relatively pathogenic bacteria count in the gastrointestinal tract and notably contributed to enhanced growth of beneficial bacteria.

In order to explore the changes of intestinal flora and serum levels of relevant substances in patients with gastric cancer before and after surgery with carbon nanoparticle laparoscopy, a total of 180 patients with early distal gastric cancer who adopted laparoscopic radical gastrectomy for distal gastric cancer in the general surgery department of TCM Hospital of Shi Jia Zhuang City from January 2018 to January 2020 were selected and randomly divided into two groups: traditional laparoscopic operation (control group) and carbon nanoparticle laparoscopic operation (experimental group) were adopted for treatment for the two groups, respectively. Postoperative evaluation included the difference between the two groups in the operative time, the efficiency of intraoperative lymph node dissection, and the number of lymph node detection. The adverse reactions, changes of intestinal flora before and after surgery in the two groups, and the serum levels of epidermal growth factor receptor (EGFR), interleukin-32 (IL-32), and gastrin 17 were evaluated. In the experimental group, the success rate of carbon nanoparticle tracer black staining reached 100%, and the operation time of the experimental group was significantly shorter than that of the control group ( P < 0.05 ). The lymph node detection rate of the experimental group was higher than that of the control group ( P < 0.05 ), but there was no significant difference in the lymph node metastasis rate between the two groups ( P > 0.05 ). The sentinel lymph node sensitivity of the experimental group reached 92.3%, and the specificity, accuracy, and positive and negative prediction rates reached 100%; the experimental group patients were with an obviously higher incidence of level I-II gastrointestinal reaction ( P < 0.05 ). Postoperative increases in Bifidobacteria and Lactobacillus were observed in both groups, while decreases in Enterococcus and Escherichia coli were observed in both groups ( P < 0.05 ). Moreover, the degree of increase and decrease in the experimental group was greater than that in the control group ( P < 0.05 ). The serum levels of EGFR, IL-32, and gastrin 17 in the two groups were significantly lower than those in the control group on 3 d, 7 d, and 15 d after surgery ( P < 0.05 ). In the radical gastrectomy for distal gastric cancer, carbon nanoparticle laparoscopy was not only helpful for the localization of small tumors but also for the thorough dissection of lymph nodes after the surgery, and the postoperative adverse reactions of carbon nanoparticle laparoscopy were also less, which was of great significance for the improvement of intestinal flora and the reduction of serum levels of EGFR, IL-32, and gastrin 17 in gastric cancer patients.
