Children have unique physiological and pathological characteristics, and their various system diseases are closely related to immune function, such as respiratory system, digestive system, nervous system, endocrine system, etc. These correlations are directly or indirectly related to the intestinal micro-ecosystem. In recent years, more and more study results show that as a major component of the human micro-ecosystem, the intestinal micro-ecosystem plays a decisive role in the important physiological functions of children such as immunity, metabolism, nutrition, etc. Children's intestinal micro-ecosystem is also associated with the treatment and prognosis of infectious diseases, chronic intestinal inflammatory diseases, allergic diseases, autoimmune diseases and metabolic diseases. In this paper, the related research of intestinal micro-ecology and some common diseases in pediatrics were summarized and discussed, the correlation between intestinal micro-ecology and pediatric diseases were deeply analyzed, in order to further understand the potential pathogenesis of pediatric diseases, and to provide new ideas for guiding the clinical treatment and long-term rehabilitation.

Objective:To observe the clinical efficacy of the rehabilitation technique of "regulating abdomen and dredging collaterals" in the treatment of children with global developmental delay (GDD), and to provide clinical experience and basis for promoting the rehabilitation treatment of GDD.Methods:Eighty-two children with GDD were selected and divided equally into the control and the treatment group according to the random number table method. The control group received conventional rehabilitation treatment, and the treatment group received "regulating abdomen and dredging collaterals" rehabilitation treatment on the basis of the conventional rehabilitation treatment. The duration of treatment for both groups was 5 times a week for 3 months. The developmental quotient (DQ) of the children in both groups was recorded using the Geselll Developmental Scale as an assessment tool to observe the scores of the five functional areas, i.e. gross motor, fine motor, language, adaptive, and personal-social.Results:At the end of the treatment, the DQ values of the children in both groups improved significantly in each energy area (all P<0.05). The treatment group outperformed the control group in terms of total effective rate and gross motor, language, and adaptability (all P<0.05), while the differences between the two groups in fine motor and personal-social energy areas were not statistically significant (all P>0.05). Conclusions:The "regulating abdomen and dredging collaterals" rehabilitation technique is clinically effective in the treatment of GDD, with significant improvement in gross motor, language, and adaptive energy areas.

Objective:To investigate the clinical effect of the "Tongluo" technique on gastrocnemius muscle hardness and muscle tone in children with spastic cerebral palsy (SCP) using shear wave elastography (SWE).Methods:Forty children with SCP who were treated at the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine from January 2020 to June 2021 were selected as the observation group and received the "Tongluo" technique intervention. At the same time, 20 normal children were selected as the control group, without any intervention. Compare the various indicators of the two groups at baseline and after 1.5 and 3 months of treatment, including Young’s modulus value of the medial gastrocnemius muscle at rest, the modified Ashworth scale (MAS) score, and the clinical spasm index (CSI) score. The changes in muscle tone and spasticity of SCP children before and after treatment were compared, and the differences in the Young’s modulus between MAS and CSI levels in SCP children as well as the correlation between MAS, CSI, and Young’s modulus were analyzed.Results:The difference in Young’s modulus values of the control group at baseline, after 1.5 and 3 months of treatment was not statistically significant (all P > 0.05). At baseline, after 1.5 and 3 months of treatment, Young’s modulus value, MAS score, and total CSI score gradually decreased in the observation group, and the differences obtained from pairwise comparisons were statistically significant (all P < 0.01). At the same intervention stage, Young’s modulus value of the observation group was higher than that of the control group, with a statistically significant difference ( P < 0.01). The MAS score results showed that Young’s modulus of the observation group increased with the increase in muscle tone, and there was a positive correlation between Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different muscle tones was statistically significant ( P < 0.05). The CSI score results showed that the Young’s modulus of the observation group increased with the increase in spasticity degree, and there was a positive correlation between the Young’s modulus and muscle tone ( P < 0.01), and the difference in Young’s modulus corresponding to different spasticity degrees was statistically significant ( P < 0.05). Conclusions:The muscle hardness of children with SCP is higher than that of normal children. The "Tongluo" technique can effectively improve muscle hardness, reduce muscle tone, and effectively improve muscle spasticity in children with SCP. The principle may be related to adjusting the internal structure of muscles to reduce muscle hardness. The results of this study can guide clinical rehabilitation and evaluation.

Objective    To evaluate the efficacy of video-assisted thoracoscopic sleeve lobectomy in the treatment of central non-small cell lung cancer. Methods    The clinical data of 105 patients with central non-small cell lung cancer who underwent sleeve lobectomy surgery in the Second Hospital of Shanxi Medical University and Shanxi Cancer Hospital from December 2014 to December 2019 were retrospectively analyzed, including 83 males and 22 females, with an average age of 57.4 (32.6-77.8) years and weight of 62.5 (52.4-79.1) kg. Thirty-five patients received video-assisted thoracoscopic sleeve lobectomy (a group A), and 70 patients received traditional thoracotomy sleeve lobectomy (a group B). The operation time, intraoperative blood loss, number of lymph node dissection, postoperative complication rate, early postoperative mortality, total thoracic drainage volume at 24 hours, time of indwelling chest tube after operation, pain score at 24 hours after operation, postoperative hospital stay, postoperative short-term (1 month, 6 months and 1 year) quality of life score and postoperative 3-year survival rate of two groups were compared. Results    There was statistical difference in the operation time (228.1±24.7 min vs. 175.0±23.7 min, P=0.02), postoperative complication rate (28.6% vs. 34.3%, P=0.04), postoperative pain score at 24 h (3.6±3.5 points vs. 5.9±2.0 points, P=0.03) and postoperative indwelling chest tube time (5.0±2.9 d vs. 8.4±2.1 d, P=0.04) between the two groups. There was no statistical difference in the intraoperative blood loss (182.5±36.9 mL vs. 189.8±27.5 mL, P=0.34), number of lymph node dissections (11.1±2.6 vs. 12.3±1.9, P=0.49), early postoperative mortality (2.9% vs. 4.3%, P=0.31), total thoracic drainage volume at 24 h after surgery (346.8± 91.1 mL vs. 329.8±101.4 mL, P=0.27), postoperative hospital stay (7.9±4.2 d vs. 8.5±3.4 d, P=0.39) and 3-year postoperative survival rate (68.6% vs. 72.9%, P=0.82) between the two groups. Conclusion    Video-assisted thoracoscopic sleeve lobectomy for the treatment of central non-small cell lung cancer is safe and feasible. Compared with traditional thoracotomy for sleeve lobectomy, fewer postoperative complications occur, body recovers faster and the quality of life is higher within the postoperative 6 months. Besides, the 3-year survival rate can achieve similar oncological prognosis results.
