Endophytic fungi played an important role in the growth of its host plant. To investigate the mycorrhizal characteristics and the distribution of fungi in the root, an endangered wild plant-Dysosma versipellis was collected and observed by electron microscope. The results showed that the host was closely associated with endophytic fungi. The fungi were mainly distributed in the epidermis and cortex. The aseptate and septate fungi with swollen hyphae were observed in some cell of the cortex. The result provides a reference for the study of mycorrhizal structure of Dysosma genus and the interaction between the fungi and its host.

Objective To observe the curative effects of monosialotetrahexosyl ganglioside(GM1)on neonates with moderate and severe hypoxic-ischemic encephalopathy(HIE).Methods Eighty-six neonates with HIE were randomly divided into GM1 treatment group and control group.The control group(42 cases)were received routine treatment(including cerebrolysin and citicoline);the treatment group(44 cases)were given GM1 on the basis of routine treatment as early as possible(within 6 hours after birth).Brain CT,neonatal behavioral neurological assessment(NBNA)and children's development center of China(CDCC)at 12 months after birth were proformed in both groups.Results Brain CT,NBNA and CDCC markers in treatment group were better than those in control group(Pa

Objective To determine the effects of~(99)Tc-MDP on joint inflammation and bone destruc- tion in collagen-induced arthritis(CIA)rats model and its effect on tumor necrosis factor alpha(TNF-?). Methods CIA was induced by immunization of male SD rats with an emulsion of collagen.~(99)Tc-MDP or placebo was intravenous infused to rats for 20 days.Joint inflammation was assessed by arthritis index.Lesions of bone were assessed based on the histological changes in ankle joints,radiographic analysis in hind paw with Larsen score.Systemic TNF-?level was measured by radioimmune assay.Results~(99)Tc-MDP suppressed joint swelling(P

OBJECTIVETo discuss the therapeutic effect of thenar perforator flaps for the narrow cicatricial contracture at thumb and the first web.

METHODSFrom Aug. 2010 to Jan. 2012, 9 cases with narrow cicatricial contracture at thumb and the first web, were treated. The defect size after releasing the contracture ranged from 8 mm x 20 mm to 15 cm x 30 mm. The bilateral thenar perforator flaps beside the wound were designed which size was 10 mm x 25 mm to 15 mm x 35 mm. The wounds at donor sites were closed directly.

RESULTSAll the 9 flaps survived completely with primary healing. The patients were followed up for 6-18 months. The flaps had soft texture and good appearance. The shape of flaps and function of the fingers were satisfied after 6-18 months of follow-up. There was no scar contracture at incisions in thenar. The thumb motion was really normal. The abduction of first web was 70 degrees - 90 degrees degrees.

CONCLUSIONSThe thenar perforator flaps is one of the ideal methods for the treatment of narrow cicatricial contracture at thumb and the first web. The main artery is not sacrified.

AlM: To investigate the relationship between the anterior ischemic optic neuropathy ( AlON ) and the carotid artery change using doppler ultrasound.METHODS:Fifty-four cases of AlON patients and 54 cases of healthy control were observed, atherosclerotic spots were detected by the application of color ultrasound.RESULTS:ln AlON group of 54 patients, 38 cases appeared carotid atherosclerosis, accounting for 70%. The number of cases with hard plaque, soft plaque and mixed plaques were 18, 13, and 7 respectively, accounting for 33%, 24% and 13%. ln the control group, 20 cases were detected atherosclerotic change, accounting for 37%. And the number of cases with hard plaque, soft plaque and mixed plaques were 12, 5 and 3 respectively, accounting for 22%, 9%, 6%. Significant stenosis and velocity change were showed in neither AlON group nor control group. Compared with the control group, AlON group had more cases of atherosclerotic plaque, the difference was statistically significant (χ2=12. 836, P=0. 005)CONCLUSlON: The incidence of AlON is correlated with carotid atherosclerosis, and carotid ultrasonography is significantly valuable for AlON etiology and diagnosis.

OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.
