Objective To investigate the regulatory effect of miR-21 on ADAMTS-1 expression in pulmonary fibrosis model. Methods A mouse model of pulmonary fibrosis was established using bleomycin (BLM) anda model of pulmonary fibrosis was constructed in vitro , the expression level of miR-21 was measured by quantitative real-time polymerase chain reaction (qRT-PCR), while the protein expression of ADAMTS-1 was measured by Western blot. NIH3T3 were transfected with miR-21 mimics and inhibitor in vitro and the cellular expression of ADAMTS-1 was measured by Western blot. Results Compared with the blank group , in mouse models of pulmonary fibrosis , the miR-21 expressions in lung tissues at three time points after BLM-treatment were significantly up-regulated while an evident decrease in ADAMTS-1 expressions were observed (P < 0.01). In vitro pulmonary fibrosis model , NIH3T3 cells after TGF-β1 in concentration 5 μg/L stimulation down-regulated ADAMTS-1 expression and up-regulated miR-21 expression (P < 0.01). NIH3T3 transfected with miR-21 mimics and inhibitor, up-regulated miR-21 expression, while down-regulated ADAMTS-1 protein expression. Conclusions Up-regulation of miR-21 and Down-regulation of ADAMTS-1 might be involved in the progression of pulmonary fibrosis model; miR-21 could negatively regulate ADAMTS-1 expression.

?AlM: To analyze the result of ultrasound biomicroscopy ( UBM ) of patients with rhegmatogenous retinal detachment ( RRD ) who need to perform pars plana vitrectomy ( PPV ) to explore the value of clinical application of UBM at preoperation.
?METHODS:Patients who underwent PPV for RRD in our hospital from January to December 2014 were selected. The preoperative results of UBM were recorded and the positive findings of UBM were analyzed, the value of preoperative application of UBM was investigated.
?RESULTS:Totally 356 cases (357 eyes) of patients with RRD were received PPV. All patients were examined by UBM, 122 eyes ( 34. 17%) were positive, 56 eyes were ciliochoroidal detachment, 28 eyes were narrow anterior chamber angle, 6 eyes were chamber angle-closure, 28 eyes were ciliary body cyst, 4 eyes were iris cyst, 11 eyes were anterior proliferative vitreoretinopathy, 1 eye was retinal cyst. There were 12 eyes existing two lesions at the same times. ln this study, patients with choroidal detachment was detected by UBM in 56 eyes, the positive rate was 15. 7%, while 25 eyes was detected by B -ultrasonography, the positive was 7. 0%. The difference was statistical significant(χ2=13. 382, P<0. 05).
?CONCLUSlON: The patients with RRD have underwent PPV for the condition of illness, preoperative UBM can be examined to detect the condition of anterior chamber angle, iris, ciliary and anterior choroid, which is significant for comprehensively understanding the preoperative condition of patients, estimating the difficulty of the operation, and guiding operation and the postoperative follow-up.

In order to identify the chemical constituents of Yushu tablets comprehensively, we studied the chemical constituents of CHCl3 extract from Yushu tablets by the ultra performance liquid chromatography-electrospray ionization-ion trap-time of flight mass spectrometry (UPLC-ESI-IT-TOF/MS). It showed that there were more than 100 compounds separated, and forty-nine peaks among these were identified on the basis of high resolution mass spectrometry data and literature data reported. Determination of twelve peaks was further confirmed by standard substances. These components assigned to the different plant sources mainly included phenylpropanoids, triterpenoids, quinones and m-trihydroxybenzene compounds. By analyzing the chemical components of CHCl3 extract from compound Chinese medicine Yushu tablets comprehensively, this study provided the foundation for studying chemical components, pharmacodynamic substance and quality control of Yushu tablets.

AIM: To determine the effect of endogenous histamine on transient forebrain ischemia-induced neuronal injury at the late phase of reperfusion using histidine decarboxylase knockout ( HDC-KO) mice.METHODS:Wild-type (WT) and HDC-KO mice were subjected to bilateral common carotid artery occlusion for 30 min followed by 3 d or 15 d of reperfusion.At different time points after reperfusion, the body weight, mortality rate, learning and memory in fear conditioning test and hippocampal CA 1 neuronal density were evaluated .RESULTS: At 1 d after reperfusion , the body weight loss was observed in both WT and HDC-KO mice.At 4 d, 5 d, 6 d and 7 d after reperfusion, the increment in the body weight of the HDC-KO mice was significantly smaller than that of the WT mice .During the period between 8 d and 14 d after reperfusion, the mortality rate of the HDC-KO mice was higher than that of the WT mice (P<0.05).At 14 d after reperfusion , the HDC-KO mice exhibited more aggravated deficits in contextual and cue memory compared with the WT mice.Correspondingly , a more severe CA1 neuronal injury in the HDC-KO mice than that in the WT mice was ob-served at 15 d but not at 3 d after reperfusion (P<0.05).CONCLUSION:Endogenous histamine may attenuate learn-ing/memory deficits and neuronal injury at the late phase of ischemia /reperfusion.However, the involved mechanisms need to be further investigated .

Objective: To evaluate the clinical efficacy and safety of domestic faropenem in the treatment of acute bacterial infections. Methods: A multicenter, randomized, double blind and double simulation clinical study was conducted to compare the efficacy and safety of faropenem and cefaclor in the treatment of acute bacterial infection. Patients in trial group(n = 122) were given faropenem 250 mg，and in control group (n = 118) were given cefaclor 200 mg，3 times daily for 7 to 10 days.Results: The clinical cure rates were 33.61% and 27.12% in trail and control groups respectively and the clinical effective rates were 87.70% and 83.05% respectively. There was no significant difference in terms of clinical effectiveness between the two groups（P > 0.05）. The adverse reaction rates were 7.32% in trial group and 3.36% in control group（P > 0.05）. The adverse reaction of the trial group was mainly exaltation of aminotransferase, which did not affect the therapy. No severe adverse reaction was found.Conclusion: Domestic faropenem is effective and safe for the treatment of bacterial respiratory tract and urinary tract infections.
