ABSTRACT
BACKGROUND:. Growth factor starts a new epoch of the research and application of wound healing, and the effect of the combination of Chinese tradition medicine and biomedicine in wound healing is still in the discussion.OBJECTIVE: To observe the effect in promoting wound healing of rats with bletilla colloid, a Chinese herbal medicine, as a carrier of exogenous high molecular weight nerve growth factor (HMW-NGF).DESIGN: The single sample observation was adopted in the identification of activities of HMW-NGF; The randomized control experiment with animal as subjects was adopted in the observation of the effect of the HMW-NGF mixed with the bletilla colloid as a carrier in promoting wound healing.SETTING: Department of Orthopaedics, Shenzhen Buji People's Hospital,and Department of Orthopaedics, Tongji Hospital Affiliated to Huazhong University of Science and Technology.MATERIALS: Forty SD rats aged 90-120 days of either gender were employed, with the body mass of 220-280 g; The freeze dried preparation of cattle seminal fluid with HMW-NGF with 1mg each.METHODS: From September 2001 to December 2004, the experiment was carried out in the Department of Orthopaedics in Shenzhen Buji People's Hospital and Central Laboratory of Department of Orthopaedics in Tongji Hospital Affiliated to Huazhong University of Science and Technolcolloid, HMW-NGF, HMW-NGF+ bletilla colloid were added into the serum-free medium (SFM), and the influences of them on the dorsal root lected and divided into 4 groups with 10 rats in each group. The rats of normal control group had no medicine on the wound. In the bletilla colloid group, the HMW-NGF group and the HMW-NGF+bletilla colloid group, incision size 2 cm was made at the back of each rat, and bletilla colloid,HMW-NGF, HMW-NGF+ bletilla colloid were applied respectively on the wound, once per day. The wound area was measured at day 3 and 10 after treatment, and the wound area was calculated by the image analysator. The category and the quantity of the emigrated cells were observed with light microscope, and the healing time of the wound was observed.tion under light microscope.the DRG of chick embryo was cultured, the reaction of evection growth around the ganglion in the HMW-NGF, HMW-NGF+ bletilla colloid with the dilution desity of 1:106-1: 108 was most significant, which was not seen in healing with HMW-NGF + bletilla colloid was significantly increased as compared with that in normal control group, the bletilla colloid group and the The healing time of the wound of the normal control group, the bletilla colloid group and the HMW-NGF group and the HMW-NGF+ bletilla colloid group were (19.5±0.7), (17.3±0.6), ( 16.6±0.7 )and ( 14.9±0.4 ) days respecvation of cut sheets 3 days after treatment: The quantity of polymorphonuclear leucocytes, histoleueocyteand fibroblast in the bletilla colloid group,the HMW-NGF group and the HMW-NGF+ bletilla colloid group were significantly larger than that in the normal control group, and the micrangium could be seen in the HMW-NGF group and the HMW-NGF+ bletilla colloid group. The observation of cut sheets 10 days after treatment: The granulation tissue in the HMW-NGF group and the HMW-NGF+ bletilla colloid group was compacter and had more micrangium as compared with the normal control group and the bletilla colloid group.CONCLUSION: HMW-NGF+ bletilla colloid has significant effect on promoting the healing of the wound at the earlier and later period, and the effect is better than that of bletilla colloid or HMW-NGF.
ABSTRACT
Objective To evaluate the relationship between intraocular pressure (IOP) and anterior chamber angle in patients with different types of acute angle-closure glaucoma after phacoemulsification and intraocular lens implantation. Design Retrospective case series. Participants 173 cases of acute angle-closure glaucoma coexisting cataract (173 eyes) in Mingren Eye Hospital from January, 2005 to June, 2007. Methods All patients with acute angle-closure glaucoma underwent phacoemulsification and intraocular lens implantation, and were examined with high-frequency ultrasound biomicroscopy (UBM). Anterior chamber depth (ACD), intraocular pressure (IOP) and anterior chamber angle (ACA) were measured. Follow-up was 1-48 weeks after surgery. Main Outcome Measures Intraocular pressure, phacoemulsification complications, re-open rate of anterior chamber angle. Results At 8th week after surgery, the rate of IOP control in pupillary block group, non-pupillary blocking group, and multimechanism group was 88.9%, 52.0%, 83.4%, respectively and there was a statistically significant between these groups (?2=7.13, P=0.022). At 48th week, the rate of IOP control was 54.2%, 33.3%, 35.8%, respectively(?2=12.56, P=0.003). Fifty patients were follow up with UBM, and 66.7% in pupillary block group, 33.3% in non-pupillary blocking group and 33.3% in multimechanism group in 48 weeks postoperatively showed evidence of the widened anterior chamber angle. No specific postoperative complications were found in this study compared with those with phacoemulsification without glaucoma. Conclusions The use of phacoemulsification and intraocular lens implantation for acute angle-closure glaucoma coexsiting cataract can get best IOP-controlled rates in pupillary block group. It is related to the degree of widened anterior chamber angle.
