Objective:To summarize characteristics and rules of blood pressure variability (BPV) in children with H-type hypertension, in an attempt to explore some basis for further selection of the time points of treatment.Methods:A total of 117 children diagnosed as essential hypertension in Children′s Hospital Affiliated to Capital Institute of Pediatrics from March 2018 to September 2019 were selected as the research objective.According to the serum level of homocysteine (Hcy), those children were divided into the simple essential hypertension group (74 cases, Hcy≤13.9 μmol/L) and the H-type hypertension group (43 cases, Hcy>13.9 μmol/L). All children received 24 h ambulatory blood pressure monitoring (24 h ABPM), and BPV indexes were recorded and subject to group comparison.Meanwhile, the serum Hcy level was monitored.Besides, the demographic data and such blood biochemical indexes as blood glucose, blood fat and renal function were recorded or measured for an analysis of the correlation between BPV and each index.Results:There were no significant differences in gender, age, body mass index (BMI) and biochemical indexes between the simple essential hypertension group and the H-type hypertension group (all P>0.05). Compared with the simple essential hypertension group, the H-type hypertension group had a significantly higher 24 h systolic blood pressure standard deviation [24 h SSD, (11.21±3.23) mmHg vs.(9.64±2.73) mmHg, 1 mmHg=0.133 kPa, t=-2.806, P<0.05], nighttime systolic blood pressure standard deviation [nSSD, (10.79±3.89) mmHg vs.(9.26±3.23) mmHg, t=-2.292, P<0.05], and nighttime diastolic blood pressure standard deviation [nDSD, (10.23±3.53) mmHg vs.(8.73±2.93) mmHg, t=-2.617, P<0.05]. Pearson correlation analysis showed that the serum Hcy level was significantly positively correlated with 24 h, SSD, nSSD and nDSD ( r=0.194, 0.183, 0.182, all P<0.05). Conclusions:24 h SSD in children with H-type hypertension is significantly higher, with an obvious increase in both nSSD and nDSD, and the serum Hcy level was significantly positively correlated with BPV, which suggested that it was required to effectively control the serum Hcy level, reduce the range of blood pressure fluctuation and select the optimal time points of treatment, thus delaying the progress of hypertension.

ObjectiveTo observe the clinical efficacy of modified Yigongsan combined with multi-enzyme tablets and bifidobacterium triple live powder on infantile anorexia with spleen-stomach Qi deficiency syndrome. MethodA total of 112 infantile patients anorexia with spleen-stomach Qi deficiency syndrome treated at Hebei Provincial Hospital of Traditional Chinese Medicine from January 2022 to June 2023 were enrolled and divided into a control group and an observation group， with 56 cases in each group， according to a random number table. Children in the control group were treated with multi-enzyme tablets and Bifidobacterium triple live powder， while those in the observation group were treated with modified Yigongsan in addition to the treatment in the control group. During the study， one case dropped out in the control group and two cases dropped out in the observation group. The clinical efficacy of the two groups of children was compared， including changes in traditional Chinese medicine （TCM） syndrome scores （main symptoms， secondary symptoms， tongue， and pulse）， time to restore normal food intake， and increase in body weight. Changes in calcium， iron， zinc levels， hemoglobin， and albumin levels before and after treatment， as well as changes in gastrointestinal hormones such as gastrin and motilin， vasoactive intestinal peptide， somatostatin， neuropeptide Y， orexin， and leptin， were observed. The occurrence of adverse reactions in the two groups of children during the study was also recorded. ResultThe total effective rate of children in the control group after treatment was 85.19% （46/54）， while that in the observation group was 98.15% （53/54） （χ² =5.939， P<0.05）. Compared with the control group， the time for food intake to return to normal in the observation group was shorter， and the increase in body weight was greater （P<0.05）. Compared with the results before treatment， the TCM syndrome scores （main symptoms， secondary symptoms， tongue， and pulse） in both groups of children significantly decreased， while the levels of calcium， iron， zinc， hemoglobin， albumin， gastrin， motilin， neuropeptide Y， and orexin increased， and the levels of vasoactive intestinal peptide， somatostatin， and leptin decreased （P< 0.01）. Compared with the control group after treatment， the improvement in the above indicators in the observation group was more significant （P<0.01）. The incidence of adverse reactions in the two groups of children during the treatment period was similar， and the difference was not statistically significant. ConclusionModified Yigongsan combined with multi-enzyme tablets and Bifidobacterium triple live powder is highly effective in treating infantile anorexia （spleen-stomach Qi deficiency syndrome）. After treatment， symptoms of the children were improved，appetite and food intake increased， gastrointestinal function was improved， body weight increased， and adverse reactions were few， indicating that the treatment was safe and reliable.
