Objective To investigate the effect of Salvia miltiorrhiza injection on proliferation , apoptosis and expression of hydroxyproline in human embryonic lung fibroblast cells. Methods TGF-β1 was administered to induce the proliferation in human embryonic lung fibroblast cells; the effect of Salvia miltiorrhiza injection on the number of human embryonic lung fibroblast cells was detected by MTT method; ki67 expression by immunocytochemical method;cell apoptosis by flow cytometry and the expression of hydroxyproline by colorimetry method. Results TGF-β1(0, 2.5, 5, 10, 20, 40 μg/L)could up-regulate cell number of human embryonic lung fibroblast cells in a dose-dependent manner , while the OD value of human embryo lung fibroblasts cells declined pretreated with Salvia miltiorrhiza injection in a dose-dependent manner and Salvia miltiorrhiza injection could induce the apoptosis and down regulated hydroxyproline expression in human embryo lung fibroblasts cells. The results of flow cytometry indicated that cell apoptosis increased after treated with Salvia miltiorrhiza injection when compared with TGF-β1 group (P < 0.05). Meanwhile, Salvia miltiorrhiza injection could down regulate the expression of hydroxyproline (P < 0.01). Conclusions Salvia miltiorrhiza injection can target human embryonic lung fibroblast cells , play a potent role in the airway remodeling through the promotion of its apoptosis and down regulate the expression of hydroxyproline.

Objective To assess the vision-related quality of life(VRQL) in patients with age-related maculopathy (AMD) and the related factors in Shanghai. Methods The VRQL of 105 patiens with AMD and 105 without (the control group) in Shanghai was investigated via Chinese-version low vision quality of life questionnaire. Resutls The Cronbach ? coefficient of the questionnaire is 0.97 in the patients with AMD, whose scores of the various quality of life were significantly lower than those in the control group. The more the exudative defect happened, or the longer the disease course developed, the lower the sccores were. All the scores of the scales and the total questionnaire were significantly related to the better or worse monocular visual acuity. The better monocular visual acuity was the first independent risk factor affecting all aspects of VRQL in pateints with AMD. Conclusions Decreased visual acutiy may gradually impair the VRQL in patients with AMD. Chinese-version questionnaire of low vision quality of life can provide the general information of the VRQL in patients with AMD.

The resistance rate to imipenem was the lowest (3.6%) and to amikacin, cefoperazone/sulbactam was 29.5%-77.4%.Conclusion The resistance rates to common the antibacterial in A.baumanii are high and the resistance pattern is wide. It is important to select antibiotics according to the antibiotics sensitivity in vitro.

Objective　To study the efficacy, safety and related characteristics of ethylcellulose microcapsules containing tubeimoside as a vascular embolization agent. Methods　The ethylcellulose microcapsules containing tubeimoside was prepared using tubeimoside from bolbostemma paniculatum of Chinese medicinal herb as the core, and ethylcellulose as the shell. Transcatheter renal arterial embolization was performed with the microcapsules in 30 New Zealand white rabbits. Results　The microcapsules were white, spherical, and smooth particles, with its size to range from 40-180 μm, and its drug content was 36%(W/W); It was divergened best in 40% meglucamine diatrizoate and suspended stably, easily injected through 3 F catheter without occlusion. All of the microcapsules ruptured in about 20 days when immersed in physiological saline at 37℃. The embolized kidneys were smaller than the normal kidneys in weight and volume after 30 days（tw=102.1, tv=38.0, P<0.001）. Serial slices of the kidneys showed that the microcapsules remained mainly at the interlobular artery and the arterial arch, which measured from 110 μm to 350 μm in diameter. The vessels maintained occlusive after 30 days without formation of collateral circulation. Conclusion　Ethylcellulose microcapsules containing tubeimoside were safe and effective with angioembolic function and slow-release. It was a potential peripheral artery embolization agent.

Objective To observe the subfoveal choroidal thickness (SFCT) and choriocapillary blood flow area (CBFA) in the patients with idiopathic macular hole (IMH).Methods This is a prospective clinical study.Thirty-two patients with unilateral IMH (4 in stage 2,17 in stage 3,11 in stage 4) and 32 age-and sexmatched normal controls were enrolled in this study.All eyes were divided into three groups,including group A (32 affected eyes),group B (32 fellow eyes) and group C (32 normal eyes of controls).There was no significant difference in age (t=0.865) and gender (x2=0.000) in IMH patients versus normal control subjects (P＞0.05).There was no significant difference in refraction (F=0.957) and ocular axial length (F=0.562) between group A,B and C.The SFCT was detected by enhanced depth imaging of spectral-domain optical coherence tomography (OCT).The CBFA was detected by OCT angiography.The differences of SFCT and CBFA in three groups were analyzed by Kruskal-Wallis and non-parametric test.Results The mean SFCT was (182.53 ±64.52) μtm in group A,(199.21 t73.07) μtm in group B and (254.21 ±56.85) μtm in group C respectively.The SFCT was thinner in group A and B than that in group C (Z=-4.362,-3.190;P＜0.05),but was the same in group A and B (Z=-1.171,P＞0.05).The mean CBFA was (5.09±0.31) mm2 in group A,(5.41 ±0.20) mm2 in group B and (5.39±0.15) mm2 in group C respectively.The CBFA was reduced in group A than that in group B and C (Z=-4.467,-4.048;P＜0.05),but was samc in group B and C (Z=0.420,P＞0.05).Conclusion SFCT and CBFA are both reduced in IMH eyes.
