Objective To approach the clinical features of refractory Mycoplasma pneumoniae pneumonia (RMPP) in children and provide evidence for clinical treatment.Methods A retrospective analysis was conducted.Two hundreds and twenty children with Mycoplasma pneumoniae pneumonia (MPP) admitted to the Integrated Chinese and Western Medicine Hospital of Zhejiang Province were enrolled from January 2013 to June 2016.According to the criteria of diagnosis of MPP and RMPP,the patients were divided into a general group (172 cases) and a refractory group (48 cases).Their general information,incidence of pulmonary positive sign,laboratory data,radiological findings,complications,therapeutic situations and prognoses,etc.between the two groups were observated.Results There were no significant difference in gender distribution between the two groups,but the age of the refractory group was much older than that of the general group (years:7.15 ± 1.89 vs.4.86±2.16),and the fever duration in the refractory group was obviously longer than that in the general group (days:11.17±2.82 vs.6.27±2.29,P ＜ 0.01).the levels of C-reactive protein [CRP (mg/L):46.8 ± 18.6 vs.13.5 ± 8.4],erythrocyte sedimentation rate [ESR (mm/1 h):56.9 ± 14.8 vs.28.7 ± 10.2],incidence of positive pulmonary sign [100.0％ (48/48) vs.33.7％ (58/172)],the incidence of pulmonary segmental consolidation [81.3％ (39/48) vs.27.9％ (48/172)] and incidence of extra-pulmonary complications [83.3％ (40/48) vs.16.3％ (28/172)] were all higher in refractory group than those in general group (all P ＜ 0.01).All the patients were treated with macrolide antibiotics and traditional Chinese medicine,the patients in the refractory group was additionally treated with glucocorticoids,and a few of them were treated with gamma immunoglobulin and bronchoalveolar lavage;all of them recovered well,high temperature had returned to normal and the imageology findings recovered well,then they all discharged without any sequela such as bronchiectasis and pulmonary atelectasis.Conclusions Physicians should pay more attention to the MPP patients with longer fever duration (especially longer than 10 days),serious signs and symptoms,more complications,higher CRP and ESR and severe radiological findings.Besides early application of macrolide antibiotics,rational use of glucocorticoids,gamma immunoglobulin and bronchoalveolar lavage can be considered.

Isolated pancreatic islet cells from neonatal rats were cultured in vitro. Insulin release was significantly inhibited by interleukin-1?. Addition of testosterone to the IL-, 1?-impaired pancreatic islets could increase insulin release, suggesting a protective effect of testosterone on pancreatic islet cells. Testosterone also significantly increased the insulin content in islet cells, and this effect could be blocked by actinomycin-D, indicating that testosterone promoted the synthesis of DNA and insulin may be one of its major protective mechanism.

Objective To investigate the changes of serum transforming growth factor-β1 (TGF-β1),interleukin-10(IL-10) and interferon-γ(INF-γ) in elderly patients with hepatic fibrosis and their correlation with hepatic fibrosis.Methods One hundred and thirty-three patients diagnosed by pathological hepatic tissue were enrolled as case group who were in the first affiliated hospital of Xinxiang Medical University from 2007 to 2013.The enzyme-linked immunosorbent assay (ELISA) was applied to detect of serum levels of TGF-β1,IL-10and IFN-γ.Meanwhile 21 healthy people were recruited as control group.Results Comparison with the control group,the levels of TGF-β1 and IL-10 were significantly higher(TGF-β1:(217.4 ± 7.5) ng/L vs.(57.2±4.8) ng/L,t =15.61,P＜0.01;IL-10:(29.6 ±3.2) ng/L vs.(15.1 ±7.5) ng/L,t =11.44,P＜0.01),while IFN-γlevel was lower ((51.9 ± 3.5) ng/L vs.(75.8 ± 5.9) ng/L,P =0.03) in case group.The serum levels of TGF-β1,IL-10,IFN-γand stages of hepatic fibrosis was correlated and the correlation coefficients were 0.786,0.644 and-0.822 respectively (P ＜ 0.05).Conclusion Serum levels of TGF-β1,IL-10 and IFN-γ in patients with hepatic fibrosis are proved to be with ability of predicting the development of hepatic fibrosis and the post treatment.

Objective To clarity the role of VEGF and its receptors in laryngeal squamous cell carcinoma development and metastasis. Methods The protein and mRNA expression of VEGF and its receptors (Fit-1 and KDR) were examined by Western-blotting and semiquantitative reverse transcriptase polymerase chain reaction analysis in laryngeal squamouse cell carcinoma (20 specimens) and the adjacent non-neoplastic laryngeal tissues (18 specimens). Results The protein and mRNA expression levels of VEGF and its receptors(Fit-1 and KDR) were more abundant in laryngeal squamous cell carcinoma than that in the adjacent non-neoplastic laryngeal tissues (ordedy 4.32±2.21, 2.00±0.91. 1.20±0.55, 0.29~0.31. 2.50±1.69, 0.85±0.28. P<0.01). The expression of VEGF and its receptors(Fit-1 and KDR) in laryngeal squamous cell carcinoma was significantly higher in lymph node positive group than that in lymph node negative group (P<0.01 or P<0.05). Positive correlation was observed between VEGF and KDR in the laryngeal squamouse cell carcinoma and adjacent non-neoplastic laryngeal tissues (P<0.01). There was no correlation between VEGF and Fit-1 expression(P>0.05). Conclusion The intense expression of VEGF, Fit-1 and KDR in laryngeal squamous cell carcinoma provides strong evidence linking VEGF, Fit-1 and KDR expression to the angiogenesis associated with laryngeal squamous cell carcinoma. The positive correlation between VEGF expression and KDR expression clearly demonstrates that KDR is the main signaling receptor for VEGF in laryngeal squamouse cell carcinoma. The VEGF/KDR system plays a functional role in the progression of laryngeal squamous cell carcinoma.
