Objective To evaluate the clinical effects of fiberoptic bronchoscopy and bronchoalveolar lavage in the treatment of refractory Mycoplasma pneumoniae pneumonia.Method The clinical data of 55 children with refractory Mycoplasma pneumoniae pneumonia were retrospectively analyzed during February 2015 to February 2016.Results Among those 55 children,30 cases who received the treatment of bronchoscopy and bronchoalveolar lavage were assigned to treatment group,and the other 25 cases were assigned to control group.17 children in treatment group and 13 children in control group had lung lamellar shadow.After treatment,the improvement rates were 100％ and 69.2％ in treatment group and control group,respectively.There was significant difference between two groups (P=0.026).The total effective rate in treatment group was 96.7％,which was significantly higher than that of control group (64.0％) (P=0.006).The length of hospital stay were significantly shorter and average treatment fee were significantly lower in treatment group than those in control group (P＜0.01).There were no severe adverse reactions in treatment group.Conclusion The effects of fiberoptic bronchoscopy and bronchoalveolar lavage with local application of drug were remarkable in the treatment of refractory mycoplasma pneumonia,and there were no severe adverse reactions.

BACKGROUND:In recent years, some studies have demonstrated that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cel s in vitro. OBJECTIVE:To observe the effect of injection of human umbilical blood cord mesenchymal stem cel s and ganglioside into rat lateral ventricles on neurological functional recovery from cerebral palsy. METHODS:Total y 60 cerebral palsy neonatal rats were delivered from pregnant rats which were modes were given intraperitoneal injection of lipopolysaccharide for 2 successive days on day 17 of gestation. Then those neonatal rats were randomly divided into five groups, including model group (n=10), sham transplantation group (n=10), stem cel transplantation group (n=18), ganglioside group (n=10) and combination group (n=12). Under stereotaxic instrument, umbilical blood cord mesenchymal stem cel s or ganglioside were injected into left lateral ventricles of the rat brain, respectively, and the sham transplantation group was given the same volume of phosphate buffered saline. Two rats from the stem cel transplantation group were put to death for immunofluorescence staining at 7, 14, 21 and 28 days after transplantation, respectively, and two rats in the combination group were kil ed for immunofluorescence staining at 14 days. Besides, al rats were underwent neurologic evaluation at 28 days after transplantation. RESULTS AND CONCLUSION:The umbilical blood cord mesenchymal stem cel s could survive, migrate and differentiate, which mainly distributed in the lateral ventricle, hippocampus and cortex. At 14 days after transplantation, positive expressions of BrdU and glial fibril ary acidic protein in the combination group were significantly higher than those in the stem cel transplantation group (P<0.05). In addition, compared with the model group, the holding time significantly prolonged and foot error times significantly decreased in the latter three groups (P<0.05), as wel as in the combination group compared with the stem cel transplantation and ganglioside groups (P<0.05). These results indicate that umbilical blood cord mesenchymal stem cel s and ganglioside can both improve neurological function of rats with cerebral palsy. Given that ganglioside can promote survival and differentiation of umbilical blood cord mesenchymal stem cel s in vivo, the combined transplantation is preferred.
