Objective To evaluate effect of comprehensive health intervention on serum lipids in obese children.Methods Totally 67 obese children (obesity group) who were treated in Baoan People's Hospital re-ceived one-year comprehensive health interventions. Another 65 normal-body-weighted children were recruited as control group.The changes of body height,weight,BMI,blood pressure (BP),and serum lipids were recorded before and after interventions.Results Compared with the control group,the weight,BMI,BP,TG,and LDL-C in the obesity group significantly decreased (P<0.05 or P<0.01).The BMI,BP,and TG in the obesity group were significantly improved after intervention (P<0.05 or P<0.01).HDL-C was significantly higher than the pre-intervention level (P<0.05),while was significantly lower than that in the control group (P

Objective To detect of clostridium perfringens by qPCR in mouse models and a clinical case in order to offer early diagnosis.Methods 40 Kunming mice were randomly grouped and intramuscular injected clostridium perfringens type A in leg 0.1 ml(3.5 × 109cfu/ml or 3.5 × 108cfu/ml or 3.5× 107cfu/ml,diluted with saline),while control group was injected with 9% sodium chloride 0.1ml.The mouse models and a clinical case were detected by qPCR.Results The death rate of 3.5 × 109,3.5 × 108,3.5 × 107cfu/ml and the blank group were 90%,70%,10% and 0% after intramuscular injection for 72 h spectively.The mean Ct values among these groups were 21.21 ±2.69,28.45 ±2.74,32.49 ±2.87 and 0.00 ± 0.00(P ＜ 0.05).The Ct values of the patient were 30.67 and 30.44.Conclusions Cclostridium perfringens could be successful identified with qPCR in mouse models when the mice still did not show any symptoms.

Objective: To compare the effect of enteral and parenteral nutrition on critically ill patients. Methods: 48 patients with critically ill in ICU were randomly divided into EN group and PN group.The nutritional index and the complication were compared between groups. Results: The levels of Hb,TP and ALB were significantly increased after EN,and the rates of complications in PN group were higher in PN group than that in EN group. Conclusion: Compared to parenteral nutritional support,enteral nutritional support can improve the nutritional condition and have less complications in critically ill patients.

Objective To explore the value of bone marrow megakaryocyte counts in predicting clinical response of thrombocytopenia (TP) in systemic lupus erythematosus (SLE) patients. Methods Thirty-one patients of SLE with severe TP (platelet ≤50×109/L) from Peking Union Medical College Hospital during 2007 to 2014 with appreciable bone marrow aspiration results were retrospectively analyzed. Their therapeutic responses were stratified and the correlation with clinical and laboratory findings including the megakaryocyte counts in bone marrow were evaluated with logistic multivariate regression. Results Totally fifteen patients obtained complete response (CR), eight patients obtained partial response (PR) and eight no response (NR). Megakaryocyte counts in bone marrow were (101±26)/slide, (156±48)/slide and (34±15)/slide respectively with statistically significant difference (χ2=6.632, P=0.036). Those NR patients had less megakaryocytes in their bone marrow compared with those with clinical response (CR+PR) (Z=-2.438, P=0.015). By ROC curve method, we found 20/slide might be a good cutoff of megakaryocyte counts in bone marrow for determining the therapeutic response of immunotherapy with a sensitivity of 91% and a specificity of 63% and a AUC (area under the curve) of 0.793. Those with 20/slide or less megakaryocytes in bone marrows only had a clinical effective response rate of 29% verse a response rate of 88% in those with more megakaryocytes in bone marrow. Conclusion Megakaryocyte counts in bone marrow may provide predictive value for therapeutic response of severe TP in SLE patients. Those patients with equal or less than 20/slide megakaryocytes in their bone marrow tend to have poor therapeutic response.

Objective To analyze the clinical characteristics and treatment Methods of severe com?plications after percutaneous tracheotomy( PDT) in neurosurgery patients,and to provide reference for the treat?ment and rescue of these patients. Methods A retrospective analysis of 578 cases after PDT was performed in Neurosurgery Intensive Care Unit ( NSICU ) of Xuanwu Hospital of Capital Medical University from 2005 to 2015. The types of complications,treatment method and prognosis were analyzed. Follow?up was 3 months to 1 year. Results Eighteen cases with severe complications,including bleeding,wound infection,asphyxia caused by tracheal mucosa suffocation,airway stenosis caused by granulation tissue,subcutaneous emphysema and neu?momediastinum,etc. After treatment and active rescue,most patients recovered,no patients die directly associated with surgery. Conclusion PDT plays an important role in the treatment of patients in NSICU,but it is still pos?sible to have serious complications,so physicians must understand and be prepared for complications,and pay more attention to prevent poor prognosis.

Objective To explore the therapic effect of the combination of endovascular embolization and clinical hormone in treatment of Kasabach-Merritt phenomenon (KMP),and analyze the advantages.Methods Six cases with KMP from May 2010 to June 2012 were retrospectively analyzed.All the patients underwent large dose hormone shock therapy after admission for 7-10 d.Subsequently,selective endovascular embolization was performed using Seldinger technique under general anesthesia Then,the hormone therapy was continued for 2 weeks after embolization.The platelet count and the effect were recorded.If the area of the tumor reduction is less than 50％,3-4 courses of local hardening treatment was conducted for the residual tumor.The local treatment used multipoint puncturing of the tumor and injection drugs under X-ray fluoroscopic monitoring until the tension of local vascular increased.Results On DSA,the lesions of all the 6 cases showed rich blood supply with a large number of hybrid distribution of tumor blood vessels.The lesions disappeared in 4 cases after 1-2 weeks combination therapy and no recurrence for 0.5-1.0 year follow-up.Two cases whose tumor reduced less than 50％ after combination therapy received local hardening treatment,and faded after 3-4 courses.The number of platelet for all patients kept normal and the spirit of the patients showed great improvement,the bleeding tendency and local soft tissue swelling was in remission.Subcutaneous blood stasis and petechiae disappeared.There were no serious adverse reaction and complications.Conclusion Combination therapy with endovascular embolization and clinical hormone for Kasabach-Merritt phenomenon has a good curative effect.

Objective:To investigate the efficacy and safety of brain protein hydrolysate injection in the treatment of elderly patients with parkinson.Methods:120 patients with parkinson were selected and randomly divided into two groups.The control group (57 cases) was treated by routine treatment,while the observation group (63 cases) was given brain protein hydrolysate injection on the basis of routine treatment.The UPDRS scores,SF-36 scores and adverse reactions during treatment were observed and recorded.Results:Before treatment,the UPDRS and SF-36 scores of both groups had no significant difference (P＞0.05).After treatment,the UPDRS scores of both groups were significantly decreased,and the UPDRS score of observation group was lower than that of the control group(P＜0.05).The social function,emotional function,mental health score of observation group were higher than those of the control group(P＜0.05).During treatment,1 cases of dizziness,1 cases of nausea were found in the control group.The adverse reaction rate was 3.5％.2 cases of insomnia,1 cases of fatigue,1 cases of dizziness and 1 cases of nausea were found in the observation group.The adverse reaction rate was 7.9％.There was no statistical difference in the incidence of adverse reactions between two groups (P＞0.05).Conclusion:Brain protein hydrolysate injection had significant effect on the Parkinson.It could improve the patients' thinking ability,mental health and quality of life with high safety.
