Objective To investigate the therapeutic effect of large dose mucosolvan combined variant flow rate continuous positive airway by nasal mask on neonatal respiratory distress syndrome(NRDS).Methods One hundred and fourteen newborns with NRDS were randomly divided into treatment group(58 cases) and control group(56 cases),on the base of same combined therapy,the cases in control group only underwent oxygen-absorbing by head set with the flow rate 4-6 L/min,and the cases in treatment group were given large dose mucosolvan(Ambroxol Hydrochloride) 30 mg/(kg?d) + 5%GS 20 mL,for two times and variant flow rate continuous positive airway by nasal mask(NCPAP),the parameter setting flow rate 6-8 L/min,FiO_2 0.4-0.6,pressure 5-8 cm H_2O.The clinical symptom and blood gas analysis after 12 and 48 hours were observed and compared the changes of pa(O_2),pa(CO_2),pa(O_2)/FiO_2 in two groups.Results The dyspnea and groan in 44 cases in the treatment group lessoned or vanished,pa(O_2) rised and pa(CO_2) lowered,the oxygenation index obviously increased,the cases with RDS grade Ⅰand gradeⅡ had better therapeutic effect,and the cases with RDS grade Ⅲ(X-ray)and Ⅳ had not manifest effect,the total effective rate was 75.8% in treatment group and 26.7% in control group.There were significant difference in therapeutic effect and oxygenation index between two groups.Conclusions Large dose mucosolvan(combi)-ning variant flow rate continuous positive airway by nasal mask can significantly improve the ventilation and oxygenation function and there are significant therapeutic effect in NRDS,especially in the NRDS grade Ⅰand gradeⅡ,the trachea cannula may be avoided and mechanical ventilation rate may be decreased if the therapeutic method can be used in earlier period.

Objective To detect v raf murine sarcoma viral oncogene homologue B1 (BRAF) in the synovial fluid of rheumatoid arthritis (RA) and to investigate its clinical significance in RA.Methods Synovial fluid samples were obtained from patients with RA and osteoarthritis (OA).Serum samples were obtained from patients with RA,OA and heathy controls.The presence of BRAF in the synovial fluid and sera were examined by enzyme-linked immunosorbent assay (ELISA).Western blotting was used to detect the expression of BRAF protein in the synovial tissue of RA and OA.The associations between the BRAF and the clinical features and laboratory parameters of RA were evaluated.Data analysis were performed using t test and Spearman's association analysis.Results ① The level of BRAF in the synovial fluid of RA [(84±59) ng/ml] was significantly higher than OA [(38±41) ng/ml] (t=3.290,P=0.002).② The level of BRAF in the sera of RA patients [(22.0±12.5) ng/ml] was also higher than OA [(6.8±7.5) ng/ml,t=3.882,P＜0.01] and healthy controls [(4.8±2.2) ng/ml,t=6.766,P＜0.01].③ In RA patients,the BRAF protein level in the synovial fluid [(102±52) ng/ml] was significantly higher than that in the serum [(21±12) ng/ml] (t=-4.316,P=0.003).④The expression level of BRAF in the synovial tissue of RA (0.284±0.045) was higher than that in OA patients (0.191±0.013,t=3.169,P=0.034).⑤ The level of BRAF in the synovial fluid had a negative correlation with disease duration (r=-0.40,P=0.019) and a positive correlation with rheumatoid factor (RF) levels (r=0.37,P=0.03).Conclusion The presence of BRAF in the synovial fluid and synovium of RA indicates that BRAF may play a role in the pathogenesis of RA,especially in the early stage.

Objective To investigate the mechanism of liposome PGE1 on the survival of the expanded flap.Methods The minipigs were set up as an animal model.They were divided into 2 groups.The expanded flaps (8 cm ×2 cm) were designed and elevated on the back of an minipig.An image analysis technology was used to evaluate the survival rate of the expanded flap,while realtimePCR technique was used to investigate the molecular mechanism.Results The survival area of the expanded flap in the Lipo PGE1 group was significantly enlarged (P＜0.01) compared with the control group.The VEGF,iNOS and Ang-1 gene expression decreased,but TGF-β1 gene expression increased.But there was no significant difference between two groups (P＞0.05).Conclusions The Lipo PGE1 could promote survival rate of the expanded flap,but the mechanism does not involve the regulation of VEGF,iNOS,Ang-1 and TGF-β1 gene expression.

Objective To summarize the clinical characteristics of 15 cases of Poland's syndrome and to explore the suitable treatment strategies. Methods A retrospective study of 15 adult patients with Poland's syndrome was conducted and the related literature was reviewed. According to the development of pectoralis muscles and breast, chest deformities were classified into 2 grades: mild and severe. Mild form was limited to absence of partial pectoralis major muscle, with variable hypoplasia of other minor components (such as the size of breast and the size and position of the nipple-areola complex), leading to a mild chest wall asymmetry. Severe form was characterized by absence or severe hypoplasia of the pectoralis major muscle and mammary gland with an evident chest wall asymmetry. Combined with gender, adult patients were divided into 4 types: female mild, female severe, male mild, and male severe. Each type had its own treatment strategies based on its anatomic features: silicone implant insertion for female mild type;latissimus dorsi muscular flap transposition and silicone implant insertion for female severe type;fat injection for male mild type;latissimus dorsi muscular flap transposition for male severe type of the patients. From 2003 to 2008, 15 adult cases were admitted to our ward, aged from 16 to 34 years.The case number of each type was 6, 6, 2 and 1, respectively. One severe female patients rejected any surgical interventions;the others were all treated as the above. Results Follow-up periods ranged from 6 months to 4 years. This series had got satisfactory results with good breast symmetry and natural texture. All the latissimus dorsi muscular flaps survived well. No postoperative complications, such as implant capsular contracture or implant displacement, were observed. Conclusion The manifestations of Poland's syndrome are extremely varied. This classification method is simple but useful, which could effectively direct the individualized treatment for the complete and adequate rehabilitation. Latissimus dorsi muscular flap, pedicled or free transplanted, pulsing silicone implant in females, are the first choices for severe chest deformations of this syndrome.

Objective To study clinical significance of anti-momoner C-reactive protein (anti- mCRP) antibody in systemic lupus erythematosus (SLE) and assess the relationship between serum CRP and anti-mCRP antibody.Methods Enzyme-linked immunosorbent assay (ELISA) was applied to determine serum level of anti-mCRP antibody in 113 pateints with SLE,65 patients with other rheumatic diseases,including primary Sjgren syndrome,rheumatoid arthritis,osteoarthritis,ankylosing spondylitis and systemic sclerosis,and 32 healthy controls.Serum level of CRP was evaluated by turbidimetry.Clinical manifestations and laboratory indicators of the patients were all recorded.Results Serum level of anti- mCRP antibody in SLE patients was significantly higher than that in patients with other rheumatic diseases and healthy controls,respectively (t=2.502 and 5.352,respectively,P 0.05).Titer of anti-mCRP antibody closely correlated with systemic lupus erythematosus disease activity index score (r=0.248,P0.05). Conclusions Level of Anti-mCRP antibody increased significantly in patients with SLE,which associated with disease activity of SLE and can be used as a valuable marker in evaluating activity of SLE.
