BACKGROUND: Our previous studies have found that the Kangguzengsheng Capsules can promote fracture healing.OBJECTIVE: To explore the influence of Kangguzengsheng Capsules-containing serum on the proliferation andosteogenic differentiation of bone marrow mesenchymal stem cells.METHODS: Forty Sprague-Dawley rats were randomly divided into four groups. The capsule powder was resolved into1 mL natural saline and intragastrically administered into rats according to 1.16 g/100 g, 3.48 g/100 g, 10.44 g/100 g in low,medium and high dose groups. Rats in control group were given equal volume of natural saline. After consecutiveadministration for 12 days, blood samples from the abdominal aorta were collected and serum samples were isolated andpreserved until use. Bone marrow mesenchymal stem cells were isolated and purified by the whole marrow adhesion method,and identified by flow cytometry. Harvested cells were divided into four groups and cultured in the osteogenic culture mediumcontaining different kinds of serum samples as described above. MTT method was adopted to test the cell proliferation at 24,48 and 72 hours of culture. Alkaline phosphatase activity in cells was detected at 7 and 14 days of culture. Alkalinephosphatase staining was performed at 7 days of culture, and alizarin red staining performed at 14 days of culture.RESULTS AND CONCLUSION: Compared with the blank control group, bone marrow mesenchymal stem cells showedno significant changes in the proliferative ability and alkaline phosphatase activity in the low dose group, but these twoindices were significantly increased in the high and medium dose groups at 48 and 72 hours of culture or at 7 and 14days of culture, respectively (P < 0.05). Cells positive for alkaline phosphatase and alizarin red staining were observed inthe low, medium and high dose groups, and the cell staining was most remarkable in the high dose group. To conclude,Kangguzengsheng Capsules-containing serum can promote the proliferation and osteogenic differentiation of bonemarrow mesenchymal stem cells.

This paper explored the joint teaching model between universities and hospitals.Clinical practice teaching based on medical ethics was carried out,choosing academic leader of teaching and research section of medical ethics as the core and relying on ethic committee of affiliated hospital as the support.Three teaching methods were integrated:theoretical introduction-case analysis-multi-role discussion(doctor,patient's organization,medical ethic specialist),which rendered ethical teaching more practical and operational.Facing the dilemma of present hospital environment,introducing medical ethic and other human sciences into clinical practices and other medical organization was evidently a better choice than strengthening police forces in hospital.

Objective:To evaluate facial soft tissue 3-deminsion changes of skeletal Class Ⅲmalocclu-sion patients after orthognathic surgery using structure light scanning technique .Methods:Eight patients [3 males and 5 females, aged ( 27.08 ±4.42 ) years ] with Class Ⅲ dentoskeletal relationship who underwent a bimaxillary orthognathic surgical procedure involving advancement of the maxilla by Le FortⅠosteotomy and mandibular setback by bilateral sagittal split ramus osteotomy (BSSO) and genioplasty to correct deformity were included .3D facial images were obtained by structure light scanner for all the patients 2 weeks preoperatively and 6 months postoperatively .The facial soft tissue changes were evalua-ted in 3-dimension.The linear distances and angulation changes for facial soft tissue landmarks were ana-lyzed.The soft tissue volumetric changes were assessed too .Results: There were significant differences in the sagittal and vertical changes of soft tissue landmarks .The greatest amount of soft tissue change was close to lips.There were more volumetric changes in the chin than in the maxilla , and fewer in the forehead .Conclusion: After biomaxillary surgery , there were significant facial soft tissue differences mainly in the sagittal and vertical dimension for skeletal Class Ⅲ patients .The structure light 3 D scan-ning technique can be accurately used to estimate the soft tissue changes in patients who undergo orthog-nathic surgery .

Objective To observe the effects of decimeter wave irradiation on the rehabilitation of the acute peripheral nerve injury of rats. Methods Eighty Sprague-Dawley rats(200～250 g)were randomly divided into 2 groups:group A,the decimeter wave irradiation group and group B,the blank control group.The right sciatic nerves of all the rats were crushed with forceps to establish the experimental animal model of acute peripheral nerve injury.Then the rats of group A were exposed to decimeter wave irradiation for 10 minutes every day for 8 weeks.The rats of group B were also fixed on a table as those in group A but receive no decimeter irradiation.At different time points observation with light and electron microscopy,immunochemical staining,axon morphometric analysis,electrophysiological examination were carried out.Results Morphometric analysis showed that at different time points after operation the recovery of nerves in group A was better than that in group B.Axon morphometric analysis showed that the number,the diameter and the thickness of sheath of myelinated nerve fibers in group A were greater than those in group B. Electrophysiological assessment showed that the latency was shorter,the amplitude was higher,and the nerve conduction velocity was faster in group A than those in group B at the end of 8 weeks of decimeter wave treatment after operation.Conclusion Decimeter wave had significant effects on the rehabilitation of the acutely injured peripheral nerves.

BACKGROUND: Resistin has been shown to play an important role in the pathogenesis and progression of osteoarthritis. OBJECTIVE: To investigate the correlation between resistin level in serum and synovial fluid and the severity of knee osteoarthritis. METHODS: Seventy-four patients with knee osteoarthritis and 79 healthy individuals were recruited. The Noyes score method was used to assess articular cartilage damage arthroscopically. The severity of knee osteoarthritis was evaluated according to the Western Ontario McMaster University Osteoarthritis (WOMAC) score. The radiographic severity of knee osteoarthritis was assessed by the Kellgren-Lawrence (K-L) grading system. The levels of resistin and cross linked C-telopeptide of type Ⅱ collagen (CTX-Ⅱ) in serum and synovial fluid were determined by ELISA. RESULTS AND CONCLUSION: The resistin level in the synovial fluid was positively correlated with the radiographic severity of knee osteoarthritis, WOMAC pain, WOMAC function, and WOMAC total scores, but showed no correlation with the WOMAC stiffness score. There were no significant correlations between the serum level of resistin and WOMAC total scores, subscale or K-L Grading system in the the osteoarthritis patients. Multiple regression analysis showed that the correlation between the synovial fluid level of resistin and WOMAC scores was of significance after removal of other confounding factors, and the resistin level in the synovial fluid was positively correlated with Noyes scores and CTX-Ⅱ level. These results suggest that the resistin level in the synovial fluid can serve as a potential biomarker reflecting the severity of knee osteoarthritis and cartilage degenerative degree in patients with osteoarthritis.

OBJECTIVETo evaluate the alveolar bone thickness and root length changes of anterior teeth with cone-beam computed tomography (CBCT).

METHODSCBCT scans were taken for 12 skeletal Class III patients who accepted the improved corticotomy (IC) procedures during pre-surgical orthodontics. The CBCT data in T1 (the maxillary dental arch was aligned and leveled) and T2 (extraction space closure) were superimposed and the alveolar bone thickness at root apex level and root length measurements were done.

RESULTSFrom T1 to T2, the buccal alveolar bone thickness for the upper lateral incisors increased from (1.89±0.83) to (2.47±1.02) mm (P<0.05), and for central incisors and for canines from (2.32±0.71) to (2.68±1.48) mm and from (2.28±1.08) to (2.41±1.40) mm, respectively. According to Sharpe Grading System, the root resorption grade for 69 teeth of 72 was located in Grade 1, two teeth in Grade 2, one tooth in Grade 3.

CONCLUSIONSThe improved corticotomy had the potential to increase the buccal alveolar bone thickness and the root resorption in most teeth was in Grade 1 according to Sharpe grading system.

Disease anthropology takes disease as the research object and uses anthropological methods to study disease. In the 1970s, a French anthropologist named Francois Laplantine foundedetiology and the therapeutic method to study disease using"opposite mode". Based on Francois Laplantine' s mode of disease etiology:ontologi-cal mode and relevance theory mode, this paper discussed the formulation process and relationship between ontolog-ical mode and relevance theory mode of western medicine and argued that moral trauma can be accepted for and can be attributed to the pathogenic factors in the relevance theory mode of disease etiology.
