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 explore the different characteristics of tumor recurrence after liver transplantation (LT)and hepatectomy(HC)in patients with hepatocellular carcinoma(HCC).Methods The literatures about tumor recurrence of HCC after LT and HC were reviewed and their characteristics were compared.Results There are distinctions of recurrence rates,time,common sites between the recurred tumors after LT and HC,and their correlation factors and mechanisms of recurrence are also different.Conclusion Preventive measures should be strengthened and treatments should be more targeted according to the different characteristics of tumor recurrence after LT and HC to improve postoperative life quality and increase the survival rate.

AIM:To evaluate the efficacy of treating traumatic optic neuropathy( TON) with mouse nerve growth factor.
METHODS: We searched the Cochrane Library, Pubmed, Medline, CNKI, Wanfang database and VIP to collect randomized controlled trials ( RCTs ) of using mouse nerve growth factor for TON. The quality of the included trials was assessed and poor-qualified trials were eliminated before the meta - analysis was conducted.
RESULTS:Seven RCTs with a total of 399 eyes included were retrieved, and OR=3. 78 with a 95%CI of [ 2. 35, 6.06], the difference was significant (P<0. 01).
CONCLUSION:The existing evidence supports that the prognosis of TON is better when mouse nerve growth factor are adopted in treatment, but there is still a need for well-planned, large-scale and multicenter RCTs to verify it.

PAX6 gene plays an important role in embryological development, and the mutation of this gene may result incongenital aniridia, retinoblastoma, macula hypoplasia, Peters' anomaly and so on. A brief introduction of the background PAX6 gene, and the association between PAX6 and retinal diseases were summarized in this review.

BACKGROUND:Nowadays, most of the studies regarding tissue engineering bone have mostly focused on critical-size bone defects of the backbone; however, there are less studies and reports on its spinal fusion. OBJECTIVE:To explore the feasibility of xenogeneic deproteinized cancelous bone as bone tissue engineering scaffold in the treatment of spinal intertransverse fusion. METHODS:The cancelous part in the distal femur of adult pigs was obtained to prepare xenogeneic deproteinized cancelous bone. After combined with the recombinant human bone morphogenetic protein, the xenogeneic deproteinized cancelous bone was combined with bone marrow mesenchymal stem cels to prepare tissue engineering bone. Twenty-four goats were obtained to prepare intertransverse bone bed, and randomly divided into two groups: observation and control groups. In the observation group, the tissue engineered bone was implanted into the left side, and the xenogeneic deproteinized cancelous bone of recombinant human bone morphogenetic protein was implanted into the right side. In the control group, the autologous iliac bone was implanted into the left side, and xenogenic deproteinization cancelous bone was implanted into the right side. At the 4th, 8th and 12th weeks after implantation, the fusion segment was obtained for gross observation, X-ray observation, histological observation and biomechanical testing. RESULTS AND CONCLUSION:X-ray films showed that the implant materials from these two groups were fixed wel and reliably. At different time points after implantation, the implant materials from each group were al in good position. There were no purulent and necrotic tissues around the material. Soft tissue ingrow and wraping were present. There were no effusions and necrosis surrounding the implant materials. The imaging and histological performance in the tissue engineering bone group outperformed that in the recombinant human bone morphogenetic protein xenogenic deproteinized cancelous bone group and xenogenic deproteinized cancelous bone group, which was the most close to the autogenous bone. At the 12th week after implantation, the maximum bending load in the tissue engineering bone group was the most close to the autogenous iliac bone group. There was no significant difference between these two groups. These results demonstrate that as bone tissue engineering scaffold, xenogenic deproteinized cancelous bone has a certain application feasibility in the treatment of spinal intertransverse fusion.
