Objective To study the efficacy of Liangxue-Zhuyu decoction combined with montelukast in the treatment of henoch schonlein purpura (HSP) and its influence on immunologic function. Methods A total of 95 HSP children treated in department of pediatrics from February 2014 to December 2016 were enrolled, and then were randomly divided into observation group (n=48) and control group (n=47), meanwhile another 48 healthy children admitted to a medical examination were selected as the healthy group. The patients in the control group were given the treatment of oral montelukast sodium chewable tablets before sleeping (the dose:2-6 years old 4 mg/d, 6-14 years old 5 mg/d), and the patients in the observation group accepted the therapy of Liangxue-Zhuyu decoction based on the treatment of the control group.The course of the treatment in the two groups were 30d. The time of clinical symptom regression and adverse reactions were recorded, and the clinical efficacy was evaluated. Monoclonal antibody immunofluorescence method and Enzyme-linked immunosorbent assay (ELISA) were used to detect the levels of serum T lymphocyte subsets and INF-γ and IL-10 before and after treatment, and their differences among three groups were compared. Results The effective rates of the observation group was 95.8% (46/48), which was significantly higher than 76.6% (36/47) of control group (x 2=7.441,P<0.05).The subsided time of the symptoms,including purpura(5.0 ± 1.3 d vs.6.6 ± 2.6 d,t=3.816), abdominal pain(3.1 ± 2.1 d vs.4.1 ± 2.6 d,t=2.139),joint pain(4.3 ± 1.5 d vs.5.4 ± 1.9 d,t=3.416),fecal occult blood(4.5 ± 1.5 d vs.6.1 ± 1.9 d,t=4.404)of the observation group were significantly shorter than those of the control group(P<0.05).After the treatment,the CD4(45.14% ± 9.32% vs.41.02% ± 9.97%),CD8(25.10% ± 4.69% vs.21.52% ± 5.71%)of the observation group was significantly higher than those of the control group, and the CD4/CD8(1.62 ± 0.32 vs.1.95 ± 0.35)and IL-10(33.07 ± 1.86 pg/ml vs.53.92 ± 2.98 pg/ml)of the observation group was significantly lower than this of the control group (P<0.05). Conclusions The efficacy of the Liangxue-Zhuyu decoction combined with montelukast for HSP was definite,and the effect was rapid with little side effects. The mechanism might be related to regulating the secretion of T lymphocyte and IL-10, thereby to correct Th1/Th2 cell balance and disturbance of immune function.

Objective To investigate the effect of 3％ sodium chloride injection on fluid resuscitation in children with septic shock.Methods Eighty-four children with sepsis in intensive care unit were selected and divided into two groups according to random number table method,42 cases in each group.The control group was treated with 0.9％ sodium chloride injection for fluid resuscitation.The observation group was slowly given 3％ sodium chloride injection for fluid resuscitation.The changes of the two groups were observed.The success time of fluid resuscitation,hospitalization time and success rate of the two groups were compared.Results After intervention,the systolic blood pressure,central venous pressure and 24h urine output in the observation group were (85.6 ± 4.3) mmHg,(7.1 ± 0.5) cmH2O,(250.8 ± 11.9) mL,respectively,which in the control group were (66.9 ± 2.6)mmHg,(4.6 ±0.2)cmH2O,(50.1 ± 5.0)mL,respectively,the differences between the two groups were statistically significant (t =23.536,29.361 and 98.339,all P ＜ 0.05).The success time of fluid resuscitation,hospitalization time of the observation group were (6.7 ± 1.1) h,(4.1 ± 0.2) d,respectively,which were significantly shorter than those of the control group [(18.5 ± 2.3) h,(6.3 ± 0.5) d,t =29.272,25.838,all P ＜ 0.05).The success rate of treatment of the observation group (95.0％) was higher than that of the control group (65.0％) (x2 =7.941,P ＜ 0.05).Conclusion 3 ％ sodium chloride injection can effectively treat fluid resuscitation,improve tissue perfusion,shorten the hospitalization time and improve the success rate of treatment for children with septic shock.
