Objective To study the effects of early application of integrated traditional Chinese medicine (TCM)and western medicine and massage on the incidence and severity of pneumonia and prognosis in the therapeutic course of infants with cytomegalovirus(CMV)infection infantile cholestatic hepatopathy(ICH)accompanied by gastric volvulus(GV). Methods A prospective randomized controlled trial was conducted. 120 infants 1-6 months old with CMV infection ICH and complicated with GV inpatients were divided into treatment group and control group (each,60 cases). The TCM Lidanheji(consisting of artemisiae capillaris 30 g,weeping forsythia 30 g,Chinese goldthread 5 g,prepared rhubarb 5 g,unpeeled root of herbaceous peony 30 g,cassia 5 g,fruit of citron or trifoliate orange 10 g,large-headed atractylodes 10 g,fruit of Chinese magnoliavine 10 g,pangolin scale 3 g and licorice root 5 g)for oral administration or enema and ganciclovir intravenous injection were given to both groups. In the control group,based on the above treatment,postural and diet therapy,prokinetics(domperidone)were given in cases with GV. The massage treatment was only applied for treatment of GV in treatment group. The pneumonia in both groups was treated in accord to the conventional diagnosis and treatment for infantile pneumonia,bronchiolitis,severe pneumonia and the guide and management of infantile community acquired pneumonia. The total number of cases with pneumonia and its severity occurring before and after treatment in the course of the disease,the clinical therapeutic effects of ICH, GV and infantile pneumonia,the clinical physical signs,biochemical indexes and the time of hospitalization were observed and compared between the two groups. Results Compared with control group,after treatment the curative rate and total effective rate of ICH,GV,infant pneumonia in treatment group were significantly higher〔the curative rate of ICH:83.05%(49/59)vs. 71.93%(41/57),total effective rate:96.61%(57/59)vs. 91.23%(52/57);the curative rate of GV:72.88%(43/59)vs. 51.79%(29/56),total effective rate:96.61%(57/59)vs. 78.57%(44/56);the curative rate of infant pneumonia:81.08%(30/37)vs. 67.44%(29/43),total effective rate:100%(37/37)vs. 100%(43/43),P<0.05 or P<0.01〕. In the treatment group,the total number of cases with pneumonia occurring in the therapeutic course and the incidence of severe pneumonia were significantly less than those in the control group〔the occurrence of pneumonia:12 cases vs. 21 cases,the incidence of severe pneumonia:16.67%(2/12) vs. 42.86%(9/21),P<0.05 or P<0.01〕. The enlargement of liver and spleen,the level of total bilirubin(TBil), direct bilirubin(DBil),total bile acids(TBA)and alanine aminotransferase(ALT)in two groups after treatment were significantly lower than those before treatment,the changes being more marked in treatment group(P<0.05 or P<0.01). The time of stay in hospital in treatment group was remarkably shortened(days:21.32±3.26 vs. 27.38±6.09, P<0.05). Conclusion Early interference with combined TCM and western medicine and massage for treatment of infants with CMV infection ICH accompanied by GV can significantly decrease the incidence of pneumonia and its severity occurring in the disease course,therefore this therapeutic method is beneficial to the treatment and prognosis of infants with CMV infection ICH.
