Objective To systematically review the literature evaluating efficacy and adverse events of propranolol for infantile hemangiomas (IHs).Methods We searched the Cochrane,Medline,Wiley,CNKI and Wanfang Databases for all studies on the response of IHs to propranolol only which were published between June 2008 and May 2013.Results A total of 23 studies were collected,including 14 case reports and 2 follow-up studies which were without random and control;another 6 studies were clinical controlled trials and 1 study was RCT.Total 716 patients were included,and never received other treatments before propranolol.Propranolol was initiated at a mean age of (4.5 ± 0.5)months at a mean dose of 2.1 mg/kg/day and for a mean treatment duration of (9.7±9.2) months.The effective rate for patients with IHs treated with propranolol was 97％ (691/716),and patients after treatment completion reported IHs recurred in 8.6 ％ of patients.The adverse effects rate was 31％(223/7167) which most common adverse events were changes in sleep (n=35),gastrointestinal reaction (n =52) and decreased heart rate (n =73),and 5 patients discontinued the treatment because of the serious adverse events.Conclusions This systematic review of 716 patients treated with propranolol for IHs show a high rate of efficacy and a low rate of serious adverse events,and it is a better treatment of infantile hemangioma,but we should pay more attention to the serious adverse events and strictly select indications.

Objective To investigate the effects of miR-335-5p on the proliferation and apoptosis of osteoblasts which were exposed to high glucose condition, and explore its possible molecular mechanisms. Methods MC3T3-E1 osteoblasts were divided into four groups:control group(5. 5 mmol/L glucose), high glucose group(HG group, 22. 0 mmol/L glucose), agomir-335-5p group(transfected with agomir-335-5p and exposed to 22. 0 mmol/L glucose) , and agomir negative control group( agomir NC group, transfected with agomir negative control and exposed to 22. 0 mmol/L glucose), cultured for 7 days. Cell proliferaton, cell apoptosis, expressions of miR-335-5p and dickkopfhomolog1(DKK1)mRNA,proteinlevelsofDKK1andcysteinylaspartate-specificproteinase-3(caspase-3) were detected using MTT, flow cytometry, quantitative realtime PCR and western blot, respectively. Results Compared with control group, the expression of miR-335-5p mRNA and cell proliferation in HG group were significantly decreased(P<0. 05), while cell apoptosis and the protein levels of DKK1 and caspase-3 were increased significantly(P<0. 05), the expression of DKK1 mRNA did not change (P>0. 05). The miR-335-5p mRNA expression and cell proliferation in agomir-335-5p group were higher than those in HG group and agomir NC group(P<0. 05). However, Cell apoptosis and the protein levels of DKK1 and caspase-3 in agomir-335-5p group were lower than those in HG group(P<0. 05). Conclusion High glucose inhibits the proliferation and induce the apoptosis of MC3T3-E1 osteoblast through decreasing the expression of miR-335-5p and subsequently increasing the DKK1 expression.

BACKGROUND/OBJECTIVES: Sanghuangporus sanghuang (SS) has various medicinal effects, including anti-inflammation and anticancer activities. Despite the extensive research on SS, its molecular mechanisms of action on lung cancer are unclear. This study examined the impact of an SS alcohol extract (SAE) on lung cancer using in vitro and in vivo models.MATERIALS/METHODS: Different concentrations of SAE were used to culture lung cancer cells (A549 and H1650). A cell counting kit-8 assay was used to detect the survival ability of A549 and H1650 cells. A scratch assay and transwell cell invasion assay were used to detect the migration rate and invasive ability of SAE. Western blot analysis was used to detect the expression of B-cell lymphoma-2 (Bcl-2), Bcl2-associated X (Bax), cyclin D1, cyclin-dependent kinases 4 (CDK4), signal transducer and activator of transcription 3 (STAT3), and phosphorylated STAT3 (p-STAT3). Lung cancer xenograft mice were used to detect the inhibiting ability of SAE in vivo.Hematoxylin and eosin staining and immunohistochemistry were used to detect the effect of SAE on the structural changes to the tumor and the expression of Bcl-2, Bax, cyclin D1, CDK4, STAT3, and p-STAT3 in lung cancer xenograft mice. RESULTS: SAE could inhibit lung cancer proliferation significantly in vitro and in vivo without cytotoxicity. SAE suppressed the viability, migration, and invasion of lung cancer cells in a dose and time-dependent manner. The SAE treatment significantly decreased the proapoptotic Bcl-2/Bax ratio and the expression of pro-proliferative proteins Cyclin D1 and CDK4 in vitro and in vivo. Furthermore, SAE also inhibited STAT3 expression. CONCLUSIONS SAE reduced the cell viability and suppressed cell migration and invasion in human lung cancer cells. Moreover, SAE also exhibited anti-proliferation effects in vivo. Therefore, SAE may have benefits in cancer therapy.

Objective Evaluating the effects of Bushen-Gufeigao and breathing movements on the patients with chronic obstructive pulmonary disease of Lung and kidney deficiency TCM pattern. Methods The patients with chronic obstructive pulmonary disease of lung and kidney deficiency TCM pattern were recruited and randomly divided into two groups the treatment group (32 cases) and the control group (34 cases). The control group was treated with the conventional medicine, and the treatment group were added Bufei-Gushengao and breathing movements based on the treatment of control group. Both groups were treated for 1 month. The changes of the clinical symptoms, lung function and frequency of attack and duration of each attack in 10 months after treatment were observed. Results After the treatment, compared with the control group, the TCM patterns scores (5.32 ± 2.67 vs. 9.12 ± 4.11, t=4.424) of the treatment group significantly decreased, while the FVC (3.00 ± 0.49 L vs. 2.71 ± 0.47 L, t=2.408), FEV1 (2.27 ± 0.44 L vs. 1.85 ± 0.54 L, t=3.496), and the percentage of FEV1%(75.62 ± 6.84 vs. 66.86 ± 9.32, t=4.333) increased significantly. In the 10 mouths after the treatment, the treatment group showed significantly fewer patients who had attacked more than 6 times than that in the control group, and the duration of attacks showed significantly fewer minutes in the treatment group than the control group (5.56 ± 1.45 d vs. 8.06 ± 1.80 d, t=6.190). Conclusion Bushen-Gufeigao and breathing movements can effectively improve patient's lung function and symptoms.
