ObjectiveTo explore the risk factors of pulmonary complications in children with mycoplasma pneumoniae pneumonia.MethodsClinincal data of 341 children with mycoplasma pneumonia were retrospectively analyzed.Children under 2 months were divided into study group and control group according to X-ray or lung CT,the study group of children left lung sequelae in children and the control group without sequelae.Using statistical analysis methods to study the children age,sex,hot process,symptoms,signs,lung lesions,lesion type,white blood cells,erythrocyte sedimentation rate,C-reactive protein,antibiotics,gamma globulin,glucocorticoid application.ResultsAt electasis 30 cases,3 cases of bronchiectasis,bronchiolitis obliterans in 1 case.Logistic regression analysis showed that children fever ＞ 10d,pleural effusion,lesion in the right upper lung,X-ray showed a large shadow,pulmonary complications in children with pulmonary high risk of complications,including chest plot sequelae in children with lung fluid was a strong risk factor( P ＜ 0.01,OR =7.684).ConclusionChildren of fever ＞ 10d,pleural effusion,lesion in the right upper lung,X-ray showed a large shadow,pulmonary complications in children with pulmonary high risk of complications,clinical treatment should be noted.

OBJECTIVE To design pharmaceutical care pathway for the problems related to chemotherapy， and to evaluate whether it contributes to the detection and intervention of drug-related problems （DRPs） in chemotherapy patients. METHODS The pharmaceutical care pathway table and flow charts were constructed and implemented by pharmaceutical care practice experience. The patients who were admitted to our hospital for chemotherapy before and after the implementation of the pharmaceutical care pathway were divided into control group （before the implementation，60 cases） and observation group （after the implementation，64 cases）， respectively； the relevant medical records of patients in the control group were extracted to evaluate DRPs， and pharmaceutical care of chemotherapy-related problems was performed for patients in observation group to extract DRPs. The basic condition， chemotherapy condition， DRPs classification and intervention status， adverse reactions induced by chemotherapy， PCNE classification of DRPs， occurrence time of DRPs， and drug classes related to DRPs were compared between 2 groups. RESULTS There was no statistical significance in the basic situation， chemotherapy regimen and chemotherapy drug category between the two groups （P＞0.05）. DRPs occurred in 46 and 37 patients in control group and observation group， respectively. In both groups， DRPs mainly occurred during chemotherapy， and mainly in the early stage of chemotherapy. Using the new pathway， the detection of DRPs significantly increased from 52.17% in the control group to 91.89% in the observation group （P＜0.05）. The successful intervention rate of DRPs was significantly increased from 32.61% in the control group to 72.97% in the observation group （P＜ 0.05）. The incidence of adverse drug reactions significantly decreased from 28.33% in the control group to 12.50% in the observation group（P＜0.05）. The main problem type of DRPs in the control group was treatment effectiveness， which mainly involved adjuvant antitumor drugs， mainly due to the use of adjuvant anti-tumor drugs for off-label prescribing； that of the observation group was treatment effectiveness and treatment safety， which mainly involved vomiting drugs， mainly due to insufficient medication to prevent nausea and vomiting caused by chemotherapy. CONCLUSIONS The implementation of the pathway helps clinical pharmacists to detect and intervene in DRPs among chemotherapy patients， and reduces the occurrence of chemotherapy-induced adverse reactions.

Objective To explore the mechanism which drives nimbolide(NIM)in treating acute pneumonia caused by Staphylococcus aureus(S.auteus).Methods A mouse model of acute pneumonia caused by S.auteus was constructed through endotracheal intubation.After NIM treatment,the survival rate was observed,the amount of bacteria in the lung was tested by plate culture,and the expression of inflammatory cytokines in the lung tissues was detected with ELISA.After primary cultured peritoneal macrophages(PM)were infected with S.auteus,the effect of NIM on the expression of inflammatory cytokines and activation of inflammatory pathway were studied with ELISA and Western blotting,respectively.The effect of RNF114 knockdown by lentiviral shRNA infection on inflammation responses in PM was explored with ELISA and Western blotting.Results Acute infection of S.auteus in the lung could cause acute death in the mice,while NIM treatment significantly improved the survival rate and down-regulated the levels of inflammatory cytokines in the lung.However,it had no effect on the lung colonization of S.auteus in the short term.The results of in vitro experiments indicated that NIM may regulate RNF114 function to down-regulate the phosphorylation level of ERK,inhibit the activation of MAPK pathway,and thus suppress the expression of inflammatory cytokines.Conclusion NIM may inhibit the activation of MAPK pathway by regulating the function of RNF114,and thus suppress the expression of inflammatory cytokines in the lung,and finally inhibit the death of mice with acute pulmonary hyperinflammation caused by S.auteus.
