BACKGROUND: Chinese traditional osteopathy is long in history, unique in manipulation and miraculous in therapeutic effect. But people understand it more m perception rather than in theory, more in application rather than in development. There is little research truly on the bioseience.OBJECTIVE: To probe into the macro-idea of Chinese traditional osteopathy, micro-mechanisms on characters and mathematics-physics models, aiming to provide new principles and approaches of treatment for the daily increased bone trauma, fracture and sport injury.SETTING: Physics and machine-electron college of a university, and its affiliated hospital.METHODS: Based on the natural concept of "integration between heaven and human being" and new concept of holistic medicine in Chinese traditional osteopathy, the macro-idea and characters of reduction and union of fracture are generalized from the characters of natural therapy and the biomechanical mechanisms and characters of reduction and union of fracture are summarized from the micro-reaction of bone repair and union so as to discover biomechanical mechanisms and characters of reduction and union of fracture and further to set up biomechanical models and mathematics-physics expressions during the treatment.RESULTS: Chinese traditional osteopathy envelopes macro-idea of "initiative reduction-functional union" in fracture and micro-mechanism on "stress adaptability-functional adaptability" of bone repair and union.CONCLUSION: Chinese traditional osteopathy compiles with the natural,green and non-traumatic therapy in bio-natural law of bone repair and union and supports the theme of "high thought and high skill".

This case report describes a 44-year-old woman with primary spinal cord malignant melanoma localized in the lumbar region. This is a very rare lesion. The patient presented with back pain and slight weakness in her lower extremities. Magnetic resonance imaging showed hyperintense signals on T1-weighted images and hypointense signals on T2-weighted images. The entire tumor was removed surgically. The patient's postoperative clinical examination revealed mild neurological improvements. Histopathological investigations confirmed the tumor was a malignant melanoma. When treating common lesions of the lumbar spinal cord with a benign appearance, surgeons should be aware of the potential for malignant tumors.

To prepare composite phospholipid liposomes containing total alkaloids of Strychnos nux-vomica with hydrogenated soybean phosphatidylcholine (HSPC) and 1, 2-dipalmitoyl-sn-glycero-3-phosphacholine (DPPC), and compare with normal DPPC thermosensitive liposomes for thermosensitive release property. Total alkaloids were extracted from S. nux-vomica with the impregnation method and further purified. Liposomes containing total alkaloids, thermosensitive liposomes and conventional thermosensitive liposomes without thermosensitive release property were prepared by ammonium sulfate transmembrane gradients and stealth liposome technique. Their encapsulation efficiency (EE), grain size, zeta potential and drug release behavior were compared. Their EEs and zeta potentials were almost identical; but the grain sizes of composite phospholipid liposomes and thermosensitive liposomes were significantly smaller than conventional liposomes. After comparing release behaviors of the three liposomes at 37, 43 degrees C, we found that the release of composite phospholipid liposomes was significantly lower than that of thermosensitive liposomes at 37 degrees C, but higher than that of thermosensitive liposomes at 43 degrees C. Meanwhile, conventional liposomes, with a very high phase-transition temperature, showed only slight release behavior at both temperatures. The study results showed that composite phospholipid liposomes had a better thermosensitive release behavior when the dosage of lysophosphatidic was reduced by 2. 5 times.

The tetrapeptide N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP), a physiological regulator of cell proliferation, has been principally reported as a potent inhibitor of the proliferation of haematopoietic stem cells and progenitors. The purpose of this study was to investigate whether the AcSDKP may directly affect the proliferative potential of human bone marrow mesenchymal stem cells (MSCs) in vitro. We added AcSDKP to the cultures of human bone marrow mononuclear cells and measured the number and average area of MSC colonies. MTT colorimetric assay and mitotic index determination were further used to examine the proliferative state of the third passage MSCs in subcultures with or without the addition of AcSDKP. In addition, we evaluated whether AcSDKP may kill MSCs by the trypan blue dye exclusion test. The results showed that the colony forming capacity, the number of viable cells and the mitotic index were reduced in human bone marrow MSCs cultured in 1x10(-12) mol/L to 1x10(-9) mol/L AcSDKP. Maximum inhibitory activity appeared in 1x10(-11) mol/L of AcSDKP. No difference in percent of living cells was observed between the MSC subcultures with and without the addition of AcSDKP. As a result, AcSDKP within a certain range of concentrations has negatively regulatory effects on the proliferation of human bone marrow MSCs in vitro.

OBJECTIVETo select optimal media and conditions for the tissue culture of Dendrobium lituiforum.

METHODThe basic media, light illumination condition, phytohormone, and natural aqueous extracts. were tested and compared. The chlorophyll contents and soluble protein contents were measured.

RESULTN6 medium was suitable for embryo germination and growth. 1/2 MS + NAA 0.5 mg x L(-1) cordd be used as the optimal protocorm multiplying media. Culture 20 days in darkness in advance, and then in light is useful to embryo germinate. 1/2 MS+ NAA 0-0.5 mg x L(-1) is beneficial to protocorm multiplication largely. N6 + 6-BA 2.0 mg x L(-1) + NAA 0.5 mg x L(-1) + 10% potato juice is useful to protocorm differentiation. Phytohormone and potato juice added to the media promoted chlorophyll content and souble protein content. N6 + NAA 0.5 mg x L(-1) + 10% banana juice is the best medium for plantlet rootage and strengthening.

CONCLUSIONConcentration of inorganic salt, nitrogen source and illumination condition are important to embryo germination and growth. The nitrogen source type has effect on the protocorm multiplication. The chlorophyll contents and souble protein contents may be index to indicate the growth condition of plantlets, which can help to select the optimal media.

This study was purpose to examine the effect of dimethyl sulfoxide (DMSO) and Tween 80 on the growth and viability of stromal cells (BMSC), colony-forming units for granulocytes and macrophages (CFU-GM) and bone marrow endothelial cell line (BMEC) from murine bone marrow in vitro, and to analyze the concentration-effect relationship. The colony yields of colony-forming units fibroblastic (CFU-F) and CFU-GM were assessed in the murine bone marrow cell cultures at various concentrations of DMSO or Tween 80 and in the control groups. The MTT assay and trypan blue exclusion were used to determine the cell viability and percentage of survival in BMSC and BMEC cultures with or without either of these organic solvents. The results showed that the colony yields of both CFU-F and CFU-GM were decreased significantly (p<0.05 or <0.01) at the concentrations (v/v final) of 2% DMSO or 0.005%-0.01% Tween 80 respectively, as compared with control. The cell viability and percentage of survival of BMSC and BMEC cultures were significantly reduced (p<0.05 or <0.01) at 0.5%-1.0% DMSO or 0.002%-0.005% Tween 80, as compared with control. With the increase of volume fractions of these solvents, the decreased percentages of corresponding measurements were increased by degrees. It is concluded that when the concentration of DMSO or Tween 80 goes to a certain level in cell culture medium, either of the organic solvents has an inhibitory action or/and cytotoxicity on the growth and viability of BMSCs, CFU-GM and BMECs. The growth inhibition and cytotoxic response are more significant at higher concentrations of these solvents.

OBJECTIVETo study the role of different lymphadenectomy in the treatment of selected clinical-stage IA non-small cell lung cancer.

METHODSAll 115 postoperative patients admitted from January 1997 to May 2002 with pathologic-stage T1 who had been preoperatively diagnosed as clinical-stage I A non-small cell lung cancer were divided into a radical systematic mediastinal lymphadenectomy (LA) group and a mediastinal lymph node sampling (LS) group. Impacts on morbidity, N staging, overall survival (OS) and disease-free survival (DFS) were evaluated in each group respectively. Associations between clinical-pathological parameters (age, sex, tumor location, tumor size, pathological type and lymph node metastases) and OS, DFS were analyzed. The cumulative OS and DFS was calculated by the Kaplan-Meier method and compared by the Log-rank test.

RESULTSThe mean number of dissected lymph nodes was (15.98 +/- 3.05) in LA group and (6.48 +/- 2.16) in LS group with a significant difference (P < 0.01). No statistically significant difference existed in modification of N staging, OS and DFS between LA group and LS group. However, for patients with lesions of a diameter more than 2 cm, 5-year OS in LA group was significantly higher than that in LS groups (LA vs. LS = 78.2% vs. 54.5% ,P < 0.05), also 5-year DFS was significantly higher (LA vs. LS = 75.1% vs. 51.3%, P < 0.05). For patients with lesions of 2 cm or less, 5-year OS and 5-year DFS were similar in both groups. The early surgery-related parameters (duration of surgery, drain secretion and morbidity) indicated a slighter invasion in LS group. In addition, patients with large cell carcinoma and adenosquamous carcinoma were associated with significantly poor 5-year OS (P < 0.05) , and patients with lymph node metastases were associated with poor 5-year OS as well as 5-year DFS (P < 0.01).

CONCLUSIONSAfter being intraoperatively identified as T1 stage, patients with lesions of more than 2 cm in clinical-stage IA non-small cell lung cancer should be performed with LA to get a better survival, and patients with lesions of 2 cm or less should be performed with LS to decrease invasion.
