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.

Objective To investigate the relationship of ventricular and pulmonany function in preoperation,perioperation and postoperation in penumonectomies.Methods FEV 1%,FVC% and treadmill exercise test of preoperation and postoperation were compared.SPO 2 and ECG of preoperation,perioperation and postoperation also were compared.To give airway oxygen during good-lung ventilation in operation in 43 patients.Results Findings of obove mentioned markers measurement in preoperation,perioperation and postoperation at one week,three months were shown the pulmonary function of postoperation was changed appearently when FEV 1%

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.

Objective To observe the effect of rapid reduction of physical activity on bone mass (BMC), bone mineral density (BMD)and bone metabolism in growing rats. Methods 48 male SD rats were divided into the high-intensity exercise group (T1, n=12), high tolow-intensity exercise group (T2, n=12), low-intensity exercise group (T3, n=12) and control group (Con, n=12). During the first 6 weeks,the rats in T1 and T2 group ran on treadmill with high intensity, while rats in T3 group took low-intensity treadmill exercise. 6 rats were sacrificedfrom each group at the end of 6th week. BMC, BMD of femur were measured with DEXA. Alkaline phosphatase (ALP), osteocalcin(BGP), tartrate-resistant acid phosphatase (TRACP) were detected with ELISA. The exercise intensity of T2 group was reduced rapidly to alow level as in T3 group, but remained in the other 2 groups. At the end of the second 6 weeks, the other rats were investigated again. ResultsCompared with the first measurements, ALP and BGP of the T2 group decreased significantly (P<0.05), and TRACP increased (P<0.05). There was no significant difference in BMC and BMD of femur (P>0.05). Conclusion Rapid reduction of physical activity can suppressbone formation and stimulate bone resorption of long bone among growing rats.

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 .

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.
