Phyllosphere and epiphytes have attracted significant interest of more and more researchers by their unique biological characteristics. Progress of research on phyllosphere and epiphytes was summarized in this paper, and the special emphasis was put on the characteristic of phyllosphere, microbial communities, invasion and the location of bacteria on leaf surfaces. Some ideas for further studies on phyllosphere microbes were also proposed.

A total of 1140 medical workers from 8 public hospitals of secondary and tertiary levels in Anhui were surveyed with questionnaire. Their knowledge of the reform, acknowledgement of key points of the reform, desire of participating in the reform and other factors that may influence the reform were investigated as categorized by their hospital, position, title and age. This study comes up with such recommendations as reinforcing communications on public hospital reform, reforming the compensation mechanism to clarify government responsibilities, probing into a better model for multi-institution practice of certified physicians, and encouraging private capital to participate in medical service while ensuring its non-profit nature, and improving the performance appraisal mechanism to ensure incentives of medical workers. These recommendations aim to enable the health administrators in their decision making.

Objective To evaluate the imaging features of patients with vascular cognitive impairment (VCI) induced by Subcortical Ischemic Vascular Disease (SIVD), through magnetic resonance diffusion tensor imaging ( DTI ) and proton spectroscopy ( MRS ) technology. Methods A total of 52 patients with SIVD were enrolled. After analysis of scale score, 32 patients with cognitive impairment were assigned to VCI group and 20 patients with no cognitive impairment were assigned to control group. Both group received DTI and MRS examination. The mean values of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of the bilateral temporal, frontal, parietal and occipital white matter regions as well as in the bilateral centrum semiovale were calculated. The peak value of MRS of N-acetyl aspartate (NAA) , choline ( Cho), creatine (Cr) and phaseomannite ( mI ) were calculated. Results Compared with control group, FA decreased in the region of temporal, frontal, parietal as well as in the centrum semiovale , and ADC increased in VC[group ( P ＜ 0.05 ) . In the frontal regions and centrum semiovale,the VCI patients had a significant FA decrease. The ADC value increased obviously in the temperal lobe.Spectrum analysis results showed, NAA/Cr was lower than control group in VCI group in the frontal lobe (1.43 ±0.08 vs 1.53 ± 0. 92), while mI/Cr was higher than control group in the temporal lobe(0. 51 ±0. 06 vs 0. 46 ± 0. 07 ) ( P ＜ 0. 05 ). Conclusion FA in the temporal and centrum semiovale regions of VCI group and NAA in the temporal white matter regions decreased obviously. DTI and MRS could provide a reference value for early diagnosis and assessment of VCI.

Successful pain management of perioperative shoulder arthroscopy may allow patients to go home earlier, improve the quality of life in perioperative period, and facilitate rehabilitation. A comprehensive method to perioperative pain control has three stages including preoperative, intraoperative and postoperative phase. Successful pain reduction should begin preoperatively because of an excellent communication between patient and physician, moreover, preoperative analgesia also should be administered. Intraoperative efforts should include local wound infiltration and the administration of anesthetic medication intra-articularly. Postoperative management should include oral analgesics, constant infusion devices, Patient Controlled Analgesia (PCA), sedative-hypnotic drug, continuous cryotherapy and vicarious treatment.

Background Posterior capsular opacification (PCO) following the extracapsular extract of cataract is associated with the proliferation and migration of residual lens epithelial cells (LECs).Study showed that the incidence of PCO is higher in diabetic patients than those of non-diabetes.So if insulin-like growth factor-1 (IGF-1) participates in the pathogenesis of PCO deserve research.Objective This study was to explore the active mechanism of IGF-1/IGF-1 receptor (IGF-1 R) system in the migration of LECs and offer theoretical basis for clinical prevention and treatment of PCO.Methods Human lens epithelial cell lines (HLEC-B3) were cultured and passaged in DMEM.The cells were identified using fluorescence immunocytometry.IGF-1 with the concentrations of 0,30,90 μg/L were added into the medium separately for 48 hours.The numbers of migrated cells were calculated by Transwell test.The cells were cultured in DMEM containing 0,1.5,30,60,90 μg/L IGF-1,and the expressions of IGF-1 Rα and IGF-1Rβ in the cells were assayed and compared by Western bolt.Results The cultured showed the positive response for α-crystallin anibody with red fluorescence in the cellular membrane.Twelve hours after Transwell incubation,the number of migrated cells (Median) was 0(0,1),10(10,11) and 29(27,31) in the 0 μg/L IGF-1 group,30 μg/L IGF-1 group and 90 μg/L IGF-1 group,respectively,showing a significant difference among the 3 groups (Z=12.610,P=0.002).The number of migrated cells in the 30 μg/L IGF-1 group and 90 μg/L IGF-1 group was significantly more than that of the 0 μg/L IGF-1 group (both at P =0.008),and the number of migrated cells in the 90 μg/L IGF-1 group was significantly more than that of the 30 μg/L IGF-1group (P =0.009).Western blot assay showed that the expressions of IGF-1Rα and IGF-1Rβ in the cells were significantly different among the 0,1.5,30,60,90 μg/L IGF-1 groups (F=63.700,130.530,both P =0.000).The expressions of IGF-1 Rα and IGF-1Rβ were gradually elevated as increase of IGF-1 doses when then concentration of IGF-1 was ＞ 30 μg/L,with significant differences among the different concentrations groups (all at P＜0.05).Conclusions IGF-1 can upregulate the expressions of IGF-1R in HLEC-B3 cells in vitro in a dose-dependent manner.Also,IGF-1 enhances the migration ability of HLEC-B3 cells.These results suggest that activation of IGF-1/IGF-1R system may be associated with the pathogenesis of PCO.

Objective To explore role of functional neck dissection for lower collar-shaped incision at hair margin behind ear in the treatment of differentiated thyroid cancer. Methods The clinical data of 11 patients with thyroid papillary carcinoma who underwent func-tional neck dissection for lower collar-shaped incision at hair margin behind ear were retrospectively analyzed. Results The incisions of all patients were unseen in daily life and patients were satisfied with the postoperative appearances. No case of shoulder syndrome,postoperative local recurrence and distant metastasis was observed. Conclusion Functional neck dissection for lower collar-shaped incision at hair margin behind ear is effective in the treatment of differentiated thyroid cancer. Meanwhile it can obviously improve patients’ postoperative appearance and life quality,therefore it is worth clinical application.

Objective:To study the effects of dexamethasone,cyclophosphamide,cyclosporin A and mycophenolate mofetil on the expression of Dectin-1 and TLR2 receptor in RAW264.7 cell line.Methods:In vitro culturing RAW264.7 macrophages ,the cells were given different doses of dexamethasone and cyclophosphamide ,cyclosporin A and mycophenolate mofetilfor 24 h.The influence of different immunosuppresants on cell proliferation was detected by CCK-8 assay.Dectin-1,TLR2 mRNA and protein levels of change were detected with RT-PCR technique and flow cytometry .Results:CCK-8 cell proliferation toxicity experiment results showed that with the increase of the dose of dexamethasone ,cyclophosphamide ,Cyclosporin A and mycophenolate mofetil ,the different degree of inhibi-tion of RAW264.7 cell proliferation in mice can be saw after the intervention of 24 h (P<0.05).After 24 h of dexamethasone stimula-tion,Dectin-1 mRNA and protein level decreased,TLR2 mRNA and protein levels elevated (P<0.05).However cyclophosphamide had no obvious influence on Dectin-1 and TLR2 ( P>0.05 ) .Mycophenolate mofetil and cyclosporin A could both inhibit the expression of Dectin-1 and TLR2 (P<0.05).Conclusion:There are significant differences among the regulatory functions of various immunosupres -sants on the expression of pattern recognition receptors .Different immunosuppressive agents exert their inhibitory effects on immune rec-ognition process of fungal pathogens not only by selectively regulating their target PRRs expression ,but also by inhibiting the growth and proliferation of macrophages .
