Salvia miltiorrhiza is a traditional Chinese medicine (TCM) and is widely used as a clinically medication for its efficiency in treating cardiovascular disease. Due to TCM is a comprehensive system, the mechanism of S. miltiorrhiza treating cardiovascular disease through integrated multiple pathways are still unclear in some aspects. With the rapid progress of bioinformatics and systems biology, network pharmacology is considered as a promising approach toward reveal the underlying complex relationship between an herb and the disease. In order to discover the mechanism of S. miltiorrhiza treating cardiovascular disease systematically, we use the auxiliary mechanism elucidation system for Chinese medicine, built up a molecule interaction network on the active component targets of S. miltiorrhiza and the therapeutic targets of cardiovascular disease to offer an opportunity for deep understanding the mechanism of S. miltiorrhiza treating cardiovascular disease from the perspective of network pharmacology. The results showed that S. miltiorrhiza treating cardiovascular disease through ten pathways as follows: improve lipid metabolism, anti-inflammation, regulate blood pressure, negatively regulates blood coagulation factor and antithrombotic, regulate cell proliferation, anti-stress injury, promoting angiogenesis, inhibited apoptosis, adjust vascular systolic and diastolic, promoting wound repair. The results of this paper provide theoretical guidance for the development of new drugs to treat cardiovascular disease and the discovery of new drugs through component compatibility.

OBJECTIVE: This study was designed to find out the impact of micro-ecological environment on the incidence of allergic rhinitis after developing a model of allergic rhinitis on mice. METHOD: Sixty mice were randomly divided into GF group (n=30) and SPF group (n=30). Mice of GF group were fed in the germ-free environment and mice of SPF group were fed in the specific pathogen-free environment. Then each group were randomly divided into model group (20 mice) and control group (10 mice). Establish allergic rhinitis model in the mice of model group using ovalbumin (OVA) at the age of 6 weeks, observe and score the corresponding symptoms and signs that could been induced. Stain with hematoxylin eosin (HE) staining method for nasal mucosa to observe the morphological changes. Using enzyme linked immunosorbent assay to detect the concentration of IgE, IFN-γ and IL-4 in the peripheral blood serum. RESULT: The chi square test showed that the incidence of allergic rhinithis in the mice of GF group was significantly higher than that in the SPF group (P< 0. 05). HE staining showed that the nasal mucosas of allergic rhinitis positive reaction mice were highly congestive and edematous and had a large number of inflammatory cell infiltration, while there was no abnormal morphology of nasal mucosas in mice with no allergic rhinitis reaction. EOS counting displayed that the number of eosinophilic cells in nasal mucosa of positive allergic rhinitis reaction mice was increased significantly. The concentration of IgE and IL-4 in the serum of positive allergic rhinitis reaction mice was highly increased (P <0. 05), and IFN-γ was significantly decreased (P< 0.05). CONCLUSION The difference of micro-ecological environment may play a key role in the occurrence of allergic rhinitis in mice.

?AIM: To retrospectively analyze the surgical strategies and outcome of traumatic lens dislocation.?METHODS: Retrospective study. Clinical data of 105 cases ( 105 eyes ) diagnosed with traumatic lens dislocation from April to June 2014 in our hospital were recruited. According to position of dislocated lens and complicated situations, different surgical approaches were performed, including intracapsular lens extraction, phacoemulsification, vitrectomy through pars plana and lensectomy. Meanwhile, vitreo-retinal or anti-glaucoma surgeries were performed in complicated cases. Preoperative and postoperative LogMar ( Logarithm of the Minimum Angle of Resolution ) visual acuity were compared by paired t-test. Perioperative complications including expulsive choroidal hemorrhages and recurrent retinal detachment were recorded and assessed.?RESULTS: All 105 dislocated lenses were removed completely. Visual acuity of 91 eyes ( 86. 7%) were significantly improved postoperatively. The visual acuity of most patients was 0. 1-0. 3 ( 42 eyes, 40. 0%) and 1 patient’s visual acuity with lens subluxation reached more than 0. 8 postoperatively. Expulsive choroidal hemorrhages occurred in 1 eye intraoperatively and 1 eye postoperatively. Recurrent retinal detachment was observed in 2 eyes postoperatively.? CONCLUSION: According to position of the lens dislocation, personalized surgery strategy is critical for therapy of traumatic lens dislocation. Expulsive choroidal hemorrhage is one of most several complications and should be managed properly.

Objective To investigate the change of serum transforming growth factor(TGF)-?1 and vascular endothelial growth facter( VEGF) in children with different types of primary nephrotic syndrome( PNS). Methods Children involved in the experiments were divided into simple type group, 16 cases; nephrit was type group, 16 cases, collecting blood sample in prednison - pretreated stage and in prednison- treated stage;control group, 14 cases. Monoclonal EUISA detected TGF-?1 and VEGF. Results Serum level of TGF-?1 and VKGF in active stage of simple type were higher than those of remission stage. The level in nephritis type was no signifi cant difference between prednison- treated stage and prednison - pretreated stage. The level in nephritis type was significantly higher than that in simple type. Conclusion Monitoring the dynamic change of serum TGF-?1 and VEGF can assess the effect of prednison treatment,and evaluate the prognosis of nephrotic syndrome.

There were significant increase in urine protein excretion,raised malondialdehyde(MDA) level and expressions of NF-?B,p22phox and p47phox in renal tissue,and significant decrease in reduced glutathione,superoxide dismutase,vitamin C and E levels in type 2 diabetic Goto-Kakisaki rats after 12 weeks. There was obvious histomorphologic change in the kidneys.All the above indices were improved by intraperitoneal injection of?-lipoic acid(35 mg/kg q.o.d).Besides,significant positive correlations were found of MDA level to p22phox,p47phox and NF-?B in the renal tissue,?-lipoic acid seems to protect the diabetic kidney in this diabetic rat model via antioxidative effects.

ObjectiveTo evaluate the clinical safety and efficacy of SilverHawk directional atherectomy for femoropopliteal occlusive lesions. MethodsEighteen ischemia occlusive lesions in 11 patients of the lower extremity were treated with SilverHawk directional atherectomy.The mean lesion number was 1.6 ± 1. 1 per patient. The mean lesion length was ( 3.4 ± 2. 2 ) cm. The average degree of diameter stenosis was 96％ ± 14％. 9 lesions were totally occlusive. Clinical symptoms included claudication in 4 cases ( Rutherford classes: 3) and critical limb ischemia ( Rutherford classes: 4) in 7 cases. Lesions characteristics were divided by TASC classification: TASC B in 7 cases; TASC C in 1 case (in-stent occlusion); TASC D in 3 cases.Mean ABI was 0. 5± 0.4. Patency was evaluated with color duplex sonography or CTA besides clinical examination during follow-up.ResultsNine totally occlusive lesions were recanalizated successfully via intraluminal approach. 18 lesions achieved technical success (residual stenosis ＜50％ ) leaving 15％ ±7％ mean residual stenosis in mean (8 ±3)min, predilation was needed in one lesion ( in-stent occlusion) prior to atherectomy. Clinical symptoms improved or disappeared with mean ABI 1.07 ±0. 12 and Rutherford grades: 0 (n =9) and 1 (n =2). Patency rate was 100％ with mean 0. 93 ± 0. 14 ABI and Rutherford grades remain unchanged after follow-up of mean ( 9 ± 4 ) monthes.ConclusionsSilverHawk directional atherectomy is safe and effective for the treatment of lower extremity ischemia.

Objective: To evaluate the effect and safety of molecular targeted therapy of apatinib mesylate combined with multiple antigen stimulatiing cellular therapy in treatment of osteosarcoma and soft tissue sarcoma. Methods:Six patients with sarcoma were collected by the failure of surgery, radiation and chemotherapy treatment or refusal surgery, radiation and chemotherapy, and at least one month from the last treatment of surgery, radiation and chemotherapy. All of the patients at least received three cycle MASCTTM . From Day 1,everyone were given Apatinib 500 mg,po,qd ,until the disease progression. To measure the patient’s quality of life depending on EORTC QLQ-C30,meanwhile,detecting the cellular immunity function and circulating tumor cells(CTCs) of patients before treatment and one month after 3 cycle MASCTTM . At last, monitoring the cellular immune responses by the Enzyme-linked immuno spot ( ELISPOT) assay. Results: All of the four patients completed the treatment of 3 cycle MASCTTM . Only one patient reduced apatinib from 500 mg to 250 mg because of palmar-plantar erythrodyses-thesia. The response rates of the four patients received MASCTTM and apatinib mesylate after treatment were 1 for complete response (CR),3 for partial response (PR). The life quality and cellular immunity function were improved in all of the patients. ELISPOT assay suggested that the majority of antigen peptides could induce specific cytotoxic T lymphocytes( CTLs) response. The Progression-Free-Survival ( PFS) of four patients received MASCTTM and apatinib mesylate was 7,6,9 and 4 months ,while the response rates of the two patients received apatinib mesylate were 1 for ( Stable disease) SD,one for ( Progression disease) PD. And PFS of the two patients were one month and two months. Conclusion:Combination of MASCTTM and apatinib mesylate is safe,effective and were good prospects for application.
