AIM: To evaluate the effects of glycemic control on refraction in diabetic patients. METHODS: Twenty newly diagnosed diabetic patients were included in this study. The random blood glucose, HbA1c levels, fasting C-peptide and postprandial 2h C-peptide were measured before treatment. The patients with random blood glucose higher than 12.0mmol/L and HbA1c level higher than 10.0% were selected. Refraction, intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length, and axial length were measured on admission and at the end of week 1, 2, 3 and 4 during glycemic control.RESULTS: A transient hyperopic change occurred in all the patients receiving glycemic control. The maximum hyperopic change was 1.60D (range 0.50±3.20D). Recovery of the previous refraction occurred between two and four weeks after insulin treatment. There was a positive correlation between the maximum hyperopic changes and the HbA1c levels on admission (r=0.84, P<0.05). There was a positive correlation between the maximum hyperopic changes and the daily rate of blood glucose reduction over the first 7 days of the treatment (r=0.53, P<0.05). During transient hyperopia, no significant changes were observed in the intraocular pressure, radius of the anterior corneal curvature, depth of the anterior chamber, lens thickness, vitreous length and axial length.CONCLUSION: Transient hyperopic changes occur after glycemic control in diabetic patients with severe hyperglycemia. The degrees of transient hyperopia are highly dependent on HbA1c levels before treatment and the rate of reduction of the blood glucose level.

155 endophytic fungi were isolated from Equisetum arvense L.,Impatiens chinensis L. and Myriophyllum verticillatum L. They were identified to 26 taxa. The antagonistic activities of these isolates against 6 isolates of plant pathogenic fungi were tested on the medium,and 37(23.9%) isolates were activitive against one or more phytopathogens. The percentage of antifungal active isolates from E. arvense L.,I. chinensis L. and M. verticillatum L. were 13.9%,29.2% and 37.1%,respectively. It was lower than that of terrestrial plants. The active isolates were mainly belonging to 5 genera including Cladosporium,Trichoderma and Geotrichum.

Objective To observe the effects of infrasound(IS)of different frequencies and intensities on the pathological morphology of the gastric mucosa(GM)in rats.Methods One hundred and forty male Sprague- Dawley rats were randomly and evenly divided into a control group(group A),an 8 Hz 90 dB group(group B),an 8 Hz 130 dB group(group C)and a 16 Hz 130 dB group(group D).IS with these frequencies and intensities was administered daily for 2 h to all groups except group A,which received sham infrasound.The other 70 rats were ran- domly and evenly divided into a second control group(group E)and an exposure group(group F),in which the rats were continuously stimulated by IS at 8 Hz and 130 dB for 2 h a day for 14 d.The pathological morphology of the GM in each group was observed at 1 d,7 d,14 d,21 d and 28 d after IS exposure.Results①Compared with group A,GM lesion scores were significantly increased in groups B,C and D at 1 d,7 d,14 d,21 d and 28 d(P＜0.01),but not in group B at 1 d.②Compared with group B,the GM lesion scores in group C were obviously in- creased at 1 d,7 d,14 d,21 d and 28 d,while scores were also obviously improved in group C in comparison with those in group D at 14 d,21 d and 28 d(P＜0.01).③The GM lesion scores in group F decreased gradually after IS,but were still higher than those in group E at 1 d,7 d,14 d,21 d and 28 d after IS.④The ultrastructures of the chondrosome and endocytoplasmic reticulum in GM cells were deformed after 8 Hz and 16 Hz IS.Conclusion 8 Hz 90 dB,8 Hz 130 dB and 16 Hz 130 dB IS can all result in GM damage in rats.The injury severity was closely related to the frequency,intensity and duration of the IS.Rats can adapt to IS after several exposures,and the damage tends to recover automatically.

OBJECTIVETo investigate the inhibitory effects of OMT on TGF-β1-induced CFBs proliferation, and then explore the mechanism.

METHODThe experiment was randomly divided into 6 groups as following: control group (serum free DMEM), model group (20 μg x L(-1) TGF-β1), OMT low dose group (1.89 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT medium dose group (3.78 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), OMT high dose group (7.56 x 10(-4) mol x L(-1) + 20 μg x L(-1) TGF-β1), SB203580 group (p38MAPK blocking agent, 1 x 10(-5) mol x L(-1) + 20 μg x L(-1) TGF-β1). Vimentin of CFBs was identified by immunocytochemical methods, α-SMA of myFBs as well. Inhibitory effects of OMT on CFBs proliferation was detected by the MTT assay. Picric acid Sirius red staining was analyzed collagen type I and collagen type III deposition. Western blot was determined the expression of p38MAPK, p-p38MAPK, collagen type I and collagen type III.

RESULTMTT results showed that OMT significantly inhibited CFBs proliferation induced by TGF-β1 (P < 0.01) α-SMA immunocytochemical experiments suggested that OMT could protect against the CFBs proliferation. OMT could significantly decrease the deposition of collagen type I and collagen type III by Western bloting and picric acid Sirius red staining. Western blot results showed that TGF-β1 enhanced p38MAPK phosphorylation, however OMT attenuated the phosphorylation of p38MAPK induced by TGF-β1 (P < 0.01).

CONCLUSIONOMT can inhibit the CFBs proliferation induced by TGF-β1, and its mechanism may be involved in inhibiting p38MAPK phosphorylation.

Objective:To observe the effect of warm-unblocking acupuncture plus fluticasone propionate nasal spray on the pulmonary ventilation, level of interferon-γ (IFN-γ) and sleep quality in patients with allergic rhinitis (AR). Methods: A total of 112 AR patients were enrolled between January 2013 and August 2018 and were divided into an observation group and a control group by the random number table method, with 56 cases in each group. Patients in the observation group received warm-unblocking acupuncture plus fluticasone propionate nasal spray, and patients in the control group only received fluticasone propionate nasal spray. The nasal symptom score, pulmonary function indexes, the levels of IFN-γ and interleukin (IL)-4 in serum, and sleep quality in the two groups were compared. Results: After treatment, the total effective rate in the observation group was higher than that in the control group (P＜0.05). The nasal symptom score dropped in both groups after treatment (both P＜0.05), and the score in the observation group was lower than that in the control group (P＜0.05). The pulmonary ventilation indexes all increased significantly after treatment in the observation group (all P＜0.05); the forced expiratory volume in 1 second (FEV1) to forced vital capacity (FVC) ratio (FEV1/FVC) and the forced expiratory flow at 50%, 75% and 25%-75% of the vital capacity (FEF50%, FEF75%, FEF25%-75%) increased after treatment in the control group (all P＜0.05); the pulmonary ventilation indexes were higher in the observation group than those in the control group (all P＜0.05). The level of IFN-γ increased significantly after treatment in the two groups (both P＜0.05) and the level of IL-4 dropped significantly (both P＜0.05); the observation group had a higher IFN-γ level (P＜0.05) and a lower IL-4 level (P＜0.05) compared with the control group. Regarding the Pittsburgh sleep quality index (PSQI), the scores of subjective sleep quality, habitual sleep efficiency and sleep disturbances and the general PSQI score decreased significantly after treatment in both groups (all P＜0.05), and the scores in the observation group were significantly lower than those in the control group (all P＜0.05). Conclusion: Warm-unblocking acupuncture plus fluticasone propionate nasal spray can effectively control the clinical symptoms and improve pulmonary function in the treatment of AR; this approach can regulate the levels of IFN-γ and IL-4 towards the normal range in AR patients; it can also improve patient’s sleep quality. This method can produce more significant efficacy than fluticasone propionate nasal spray used alone.

With reverse transcriptase PCR, the transcripton of copper homeostasis relative gene Afe0329 in Acidithiobacillus ferrooxians standard strain ATCC23270 was investigated. The further analysis of genes in this transcripton was analyzed employed by Vector NTI, Blast, TMHMM Server, PSORTb software and so on. From the DNA of different strains, the transcripton of Afe0329 was amplified using special primer pairs to identify the universality of it in the genome of A.ferrooxidans strains. The results showed that gene Afe0330 and Afe0331 were cotranscribed with Afe0329, and they were in a single transcripton. Gene Afe0329 was supported to express a P1b3-type ATPase which is a heavy metal ion pumping transmembrane protein, protein AFE0330 which expressed by gene Afe0330 was a cytoplasmic protein, no significant ho- mologous sequences of Afe0330 or Afe0331 had been obtained by Blast analysis. And the transcripton of Afe0329 was universal in genome of A. ferrooxidans strains.
