One hundred and seventy-two strains of endophytic fungi were isolated from Taxus mairei,Cephalotaxus fortunei and Torreya grandis cv.merrillia.The result of the antifungal assay shows that ninety strains of the fungi have antagonism against one or more botanical pathogenic fungi,such as Neurospora sp.,Trichoderma sp.,Fusarium sp.etc.The percentage of antifungal strains to tested strains are as follows:40% Cephalotaxus fortunei,54.2% Taxus mairei,57.1% Torreya grandis cv.merrillia.Thirty-five strains have high antifungal activities,and their inhibition zone diameter is at least 15mm.The active endophytic fungi were identified as 18 genera,most of which belong to Paecilomyces and Fusarium etc.

OBJECTIVETo study the surgical reconstruction of secondary fracture deformities of the nasal-orbital ethmoid area.

METHODSTypical bicoronal and subciliary incisions or the adjacent scar incision were employed to expose the fractured area. The flattened nasal bone was narrowed by curved osteotomy along the medial orbital rims and trimed with a bur. 2-3 pieces of cranial outer table were used to reconstruct the nasal framework, which were fixed to the frontal bone with mini-plates. After the medial orbital wall and orbital floor were exposed, the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with autogenous cranial outer table or Medpor. The medial canthal tendons were anchored superior-posteriorly to the lacrimal fossa with transnasal wires.

RESULTSFrom December 1996 to December 2001, 34 cases of severe nasal-orbital ethmoid fracture deformities were repaired with this technique. Of them, 12 cases had combined orbital-zygomatic fracture, 4 cases had fontal sinus fracture, 1 case had Le Fort II and 1 case had Le Fort III fracture. All the patients recovered well and their facial appearance improved greatly.

CONCLUSIONSThe key points for surgical reconstruction of the periorbital post-fracture deformities are narrowing the flattened nasal root by curved osteotomy, the nasal framework reconstruction with autogenous bone graft, the orbital wall repair to correct enophthalmos, and most importantly, the medial canthal tendon reduction and canthal plasty.

OBJECTIVEFor anti-inflammation, relieving pain and decreasing acute toxicity, the best condition for extracting procedure of Psammosilene tunicoides was chosen. And the relationships between several solvent extracts and pharmacodynamic index were studied.

METHODUniform design with multi-targets was used in the optimization process, and the evaluate index were the results of anti-inflammation, relieving pain and LD50 were employed as the evaluating indexes. At the same time, the contents of the extracts, water extract, acetic ester extract and ether extract were determined.

RESULTThe best condition is that the medicinal material is optimized with 8 times of water (pH 6-7) and 2 h of each time. The best condition is satisfactory by test verification. And the pharmacodynamic actions of anti-inflammation, relieving pain and LD, were not obviously related to the dry extracts, water extract, acetic ester extract and ether extract.

CONCLUSIONUniform design method with pharmacodynamic index has the merit of being relaated to the function and symptom directly. The extracted twice technology condition optimized is stable, feasible and suitable for industry production. And it is not suitable to take the solvent extracts as quality control index related to the function and symptom.

OBJECTIVEBased on magnetic beads based weak cation exchange chromatography (MB-WCX), matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) and ClinProTools software, the polypeptides of serum about occupational medicamentosa-like dermatitis induced by trichloroethylene (OMLDT) patients were studied, and a diagnostic model of OMLDT was built.

METHODSAccording to diagnostic criteria of OMLDT, serum of 28 OMLDT patients and 28 controls which were diagnosed by Shenzhen prevention and treatment center for occupational disease were collected. With the combination of MB-WCX and MALDI-TOF-MS, the polypeptides fingerprint of serum of 14 OMLDT patients and 14 controls were detected, what's more, the ClinProTools software and SNN algorithm was used for screening characteristic polypeptides and establishing diagnostic model of OMLDT. Then other objects were applied to validate the model to evaluate accuracy.

RESULTSA total of 159 peaks were attained by ClinProTools software, of which 33 peaks were statistical content (P < 0.05). What is more, comparing with the control group, 20 peaks in case group were decreased, and 13 peaks were increased. Two peaks of them were identified, that is 2106.29 and 3263.78, to classify and determine that two groups by receiver operating characteristic curve (ROC) analysis.2D peaks distribution map certified this finding and the area under the ROC curve was closed to 1. A model was established by SNN algorithm, whose cross validation and recognition capability were 87.5% and 98.5%, respectively. Its sensitivity and specificity were 84.8% and 82.1%, separately, which displayed good separating capacity.

CONCLUSIONIn the combination of MB-WCX, MALDI-TOF-MS and ClinProTools software, specifical different polypeptides were screened and OMLDT diagnostic model was built primarily. Also, the model and the results were positively validated, which would play a significant role in early diagnosis.

OBJECTIVETo observe the difference in the efficacy on lumbar intervertebral disc protrusion (LIDP) between Santong tuina therapy and conventional tuina therapy.

METHODSMulti-central, random and controlled clinical trial was carried out. One hundred and twenty cases of LIDP were randomized into an observation group and a control group, 60 cases in each one. In observation group, Santong tuina therapy was used. In control group, conventional tuina therapy was adopted. The clinical efficacy was observed in two groups, and lumbar vertebral function was scaled before and after treatment in two groups.

RESULTSThe total effective rate was 95.0% (57/60) in observation group and was 96.7% (58/60) in control group, without significant statistical difference in comparison (P > 0.05). The cured and markedly effective rate was 81.7% (49/60) in observation group and was 63.3% (38/60) in control group, indicating significant statistical difference in comparison (P < 0.05). The self-comparison of lumbar vertebral function before and after treatment presented statistical significance in either observation group (12.25 +/- 3.15, 25.56 +/- 5.27) or control group (13.32 +/- 3.26, 20.46 +/- 4.25, both P < 0.05); additionally, there was significant difference in the comparison between groups after treatment (P < 0.05). The therapy adopted in observation group improved lumbar vertebral function much significantly.

CONCLUSIONIn the treatment of LIDP, Santong tuina therapy achieves much better clinical efficacy as compared with conventional tuina therapy.

OBJECTIVETo explore the possibility of using distraction osteogenesis to repair skull defect.

METHODS17 goats with one year age were chosen randomly. The animals were divided to 3 groups. Group A includes 7 goats, a 3.0 cm x 2.2 cm rectangle skull defect is created on both sides of parietal area. Group B includes 5 goats, a 2.2 cm x 2.2 cm square skull defect was created on right side of parietal area. Group C includes 5 goats, a 3 cm x 1 cm rectangle skull defect was created on both sides of parietal area. Accordingly, different size of transport discs were created on right side of skull and the distraction apparatus is implanted. 3-D CT was done to measure the skull defect on group A. Biomechanical test was done on group B. Process of bone formation illustrated by histological stain, scan and transparent electric microscope was observed on group C.

RESULTSGroup A measured by 3-D CT showed that skull defect of experimental side have been repaired by distraction osteogenesis. There was definitely difference between experimental and control side (P < 0.01). Group B measured by biomechanical test showed no definitely difference between experimental and normal side (maximum load P = 0.235 > 0.05, rigidity P = 0.213 > 0.05). Group C showed that the process of bone formation was typical intramembranous.

CONCLUSIONSThe evidence showed that skull defect of goat can be repaired by distraction osteogenesis.

OBJECTIVETo present a new method for correction of prominent malar complex by L-shaped osteotomy through an intraoral incision.

METHODSBased on the anatomical characteristics of the malar complex, we designed a new L-shaped osteotomy for malar eminence reduction. The procedure includes oblique incision of the upper part of the mala, vertical incision of the anterior part of the mala and "greenstick" fracture of the zygomatic arches. According to the severity of malar prominence, we resect part of the anterior-inferior part of the mala and lower the malar complex.

RESULTSThis method was used in 39 patients with prominent malar complex. Of them, 32 were symmetrical and 7 were unsymmetrical. All the patients obtained good results.

CONCLUSIONL-shaped osteotomy for correction of prominent malar complex is a relatively ideal surgical method with the advantages of simpler manipulation, fewer complications, better result, and ensuring the intactness of the structural characteristics of the malar complex.
