So far there exists no corresponding quality test procedures and grading standards for the seed of Prunus humilis, which is one of the important source of base of semen pruni. Therefor we set up test procedures that are adapt to characteristics of the P. humilis seed through the study of the test of sampling, seed purity, thousand-grain weight, seed moisture, seed viability and germination percentage. 50 cases of seed specimens of P. humilis tested. The related data were analyzed by cluster analysis. Through this research, the seed quality test procedure was developed, and the seed quality grading standard was formulated. The seed quality of each grade should meet the following requirements: for first grade seeds, germination percentage ≥ 68%, thousand-grain weight 383 g, purity ≥ 93%, seed moisture ≤ 5%; for second grade seeds, germination percentage ≥ 26%, thousand-grain weight ≥ 266 g, purity ≥ 73%, seed moisture ≤9%; for third grade seeds, germination percentage ≥ 10%, purity ≥ 50%, thousand-grain weight ≥ 08 g, seed moisture ≤ 13%.

Objective To explore the short term efficacy and safety of percutaneous transluminal renal artery stenting in patient with renal artery stenosis.Methods From January 2003 through June 2012,fifty hypertension patients with unilateral or bilateral renal artery stenosis ≥70% were successfully treated by percutaneous translumminal renal angioplasty with stent (PTRAS).There were 32 males and 18 females with an average age of (51.2 ± 12.3) years ranged from 21 ~78 years.The blood pressure level,dosage of anti-hypertension drugs and serum creatinine (Scr) of patients were documented and analyzed before and after stenting.All patients were clinically followed up for 6 months after stenting.Continuous variables were analyzed by using t-test for comparison among patients.Results The technical success rate was 100%.Of them,16 patients were cured,30 patients improved and 4 patients ineffective.There were significant differences in blood pressure,sCr and dosage of anti-hypertension drugs between post-stenting and prestenting [SBP (145.7 ±11.3) vs.(179.1 ±22.3) mmHg; DBP [(75.1±9.2) vs.(112.5 ±19.2)mmHg],sCr [(138.2 ±20.3) vs.(191.1 ±36.5) μmol/L] (P<0.01) and the dosage of antihypertension drug was dramatically decreased.And there were no adverse events found during follow-up period.Conclusions The success rate of PTRAS technique was high,and the blood pressure of patients could be effectively controlled by it,being beneficial to renal function.

AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).
CONCLUSlON: The application effect of microscopic pterygium resection combined with MMC is remarkable, and the joint of 0. 2mg/mL concentration of MMC is more safe and effective, and is worth popularizing in clinical application.

In the study, the effects of Panax notoginseng saponins (PNS) on alveolar epithelial to mesenchymal transition (EMT) and extracellular matrix degradation were observed in a type of human alveolar epithelial cell, A549 cells, stimulated by TGF-beta1. Firstly, MTT method was applied to evaluation of cellular proliferation and found that PNS from 12.5 mg x L(-1) to 200 mg x L(-1) dosage could not inhibit significantly cellular proliferation. Then, cells were divided into five groups, normal group, TGF-beta1 group, TGF-beta1 + 50 mg x L(-1) PNS group, TGF-beta1 + 100 mg x L(-1) PNS group and TGF-beta1 + 200 mg x L(-1) PNS group. Normal cells were not stimulatec by TGF-beta1; TGF-beta1 cells were only stimulated by TGF-beta1 and the other cells were stimulated by TGF-beta1 with different doses of PNS, respectively. After stimulation, cells and supernatants were collected for assays. Cellular roundness was applied to quantitative evaluation of morphological change. Immunocytochemistry was applied to examine E-cadherion, a-SMA and FN proteins expression in the cells. Enzyme linked-immunosorbent assay was applied to MMP-9 and TIMP-1 levels. The results showed that EMT of A549 cells was induced by TGF-beta1, showing significant change of roundness, E-cadherion, alpha-SMA and FN (P < 0.05, P < 0.01). Compared to TGF-beta1, PNS significantly inhibited the changes of roundness (P < 0.05), FN and alpha-SMA (P < 0.05, P < 0.01) and not significantly inhibited the change of E-cadherion. Furthermore, MMP-9 levels were significantly increased by TGFbeta1 stimulation (P < 0.05), without significant change of TIMP-1. Compared with TGF-beta1, PNS could significantly increase MMP-9 level (P < 0.05) and decrease TIMP-1 levels (P < 0.05, P < 0.01). In conclusion, PNS could inhibit alveolar epithelial cell EMT induced by TGF-beta1, with increase of extracellular matrix degradation ability, which showed anti-fibrosis of lung ability.

?AIM:To analyze the clinical features of Terrien marginal degeneration ( TMD) .?METHODS:Fifty-six patients(90 eyes) admitted in our hospital from January 2013 to January 2015 were selected as observation group.At the same period, 56 healthy (88 eyes) for corneal examination were as control group to analyze the clinical features of TMD. With immunohistochemistry and enzyme linked immunoassay method ( ELISA), the levels of HLA-DR, HLA-DQ and tumor necrosis factor-α( TNF-α) in blood samples of TMD patients were tested.?RESULTS:The transparent degree of the eye, lipid deposition in TMD patients with early, advanced, swelling and hole-wearing period were significantly different (χ2=10.85,χ2=65.32, P<0.05).Astigmatism in TMD patients with early and advanced, swelling and hole -wearing period were significantly different (P<0.05).The levels of HLA-DR, HLA-DQ and TNF-αin blood samples between the two groups were significantly different ( t=45.326, t=23.564, t=19.86, P<0.05).?CONCLUSION: Terrien's marginal degenerative is an inflammatory disease characterized by increased levels of TNF-α, HLA-DQ, and HLA-DR in peripheral blood, decreased corneal transparency, astigmatism and lipid deposition.This research provides experiment evidence for the mechanism of TMD.
