OBJECTIVETo analyze micromovement of distal tihiofihular joints in different motion range of ankle joint ,and define the micromovement characteristic and range of distal tibiofihular joints.

METHODSTwelve normal Chinese were chosen. There were 9 males and 3 females, aged from 19 to 37 years old with an average (26.5 +/- 0.5) years. Detection terminals of laser photographic scanner were installed near the highest point between medial malleolus and lateral malleolos, the change of detection terminals on the position of dorsiflex, extension, introversion and eversion of ankle joint were scanned by 3D-laser scanner. The displacement of two detection terminals on the X ,Y and Z-axis (X-axis stands for the vertical-axis between coronal plane and Z-axis Y-axis stands for the vertical-axis between sagittal plane and Z-axis Z-axis stands for macroaxis of tibia).

RESULTSAlong with increased range of motion on the position of dorsiflex ,extension, introversion and eversion of ankle joint, the range of micromovement of distal tibiofibolar joints increased too. The max-displacement of X, Y and Z were respectively (1.04 +/- 0.12) mm, (1.70 +/- 0.16) mm and--(0.87 +/- 0.10) mm.

CONCLUSION3D-laser scanner can be used to determine the detailed displacement of distal tibiofibolar joint on the X , Y and Z, and measure the motion of distal tibiofibular joint. The method can be used to study the pathologic change of distal tibiofibular joint ,and provide basic biomechnics data for internal fixtor fitting for the characteristic of distal tibiofibular joint.

OBJECTIVETo compare the difference of the clinical efficacy on common peroneal palsy between the comprehensive therapy of electroacupuncture, moxibustion and moving cupping method and western medication.

METHODSNinety cases of common peroneal nerve palsy were randomized into a comprehensive therapy group and a western medication group, 45 cases in each one. In the comprehensive therapy group, electroacupuncture was applied to Yanglingquan (GB 34), Zusanli (ST 36), Xuanzhong (GB 39), Jiexi (ST 41), Taichong (LR 3), Zulinqi (GB 41) and the others, combined with warm moxibustion and moving cupping on the lateral side of the affected leg. The comprehensive therapy was used once a day. In the western medication group, vitamin B1 , 10 mg each time, 3 times a day; and mecobalamine, 0. 5 mg each time, three times a day were prescribed for oral administration. In the two groups, 15 days made one session, and the efficacy was observed after 2 sessions treatment.

RESULTSThe total effective rate of the improvement of sensory function and motor nerve function was 97. 8% (44/45) in the comprehensive therapy group and was 82. 2% (37/ 45) in the western medication. The efficacy in the comprehensive therapy group was better than that of the western medication (P<0. 01). The electrophysiological examination showed that the amplitude of motor conduction of deep peroneal nerve and that of sensory conduction of surficial peroneal nerve after treatment were improved remarkably as compared with those before treatment in the comprehensive therapy group (both P<0. 05). The amplitude of motor conduction of deep peroneal nerve was improved significantly in the comprehensive therapy group as compared with that in the western medication group (P<0. 05).

CONCLUSIONThe comprehensive therapy of electroacupuncture, moxibustion and moving cupping method achieves the significant efficacy on common peroneal nerve palsy as compared with western medication.

BACKGROUNDTourniquets used during total knee arthroplasty may lead to many complications. The aim of this study was to determine perioperative blood loss and its clinical relevance in total knee replacement surgery after applying a tourniquet.

METHODSFrom June 2009 to October 2009, 60 consecutive patients who underwent routine total knee arthroplasty were randomly divided into two groups and were treated with or without a tourniquet (30 patients/group). There were no significant differences in patient baseline characteristics between the two groups. We compared the two groups of patients in terms of intra- and postoperative bleeding, invisible or visible bleeding, and total blood loss.

RESULTSNone of the patients showed poor wound healing, lower extremity deep venous thrombosis or other complications. The amount of blood loss during surgery was lower in the tourniquet group than in the control group (P < 0.01). However, postoperative visible bleeding (P < 0.05) and occult bleeding (P < 0.05) were significantly greater in the tourniquet group than in the control group. There was no significant difference in the total amount of blood loss between the two groups (P > 0.05).

CONCLUSIONSTourniquet can reduce bleeding during total knee replacement surgery, but is associated with greater visible and invisible blood loss.

OBJECTIVETo explore the action mechanism of the immune active components of sappon wood (SWE) for antagonizing reject reaction by observing the influence of its ethyl acetate extract on mRNA expression of myocardial GrB in rat model of allogenic ectopic cardiac transplantation.

METHODSAnimal model of abdominal cardiac ectopic transplantation was established taking Wistar rat as the donor and SD rat as the receptor. The successfully modeled rats were randomly divided into the model group, the SWE group and the CsA group. GrB mRNA expression was detected by RT-PCR method and myocardial pathomorphologic picture was observed in routine.

RESULTSThe pathologic changes in the SWE group (23 scores) and the CsA group (14 scores) were milder than in the model group (31 scores), the former two could markedly alleviate the myocardial pathologic injury (P<0.05, P<0.01). The GrB mRNA expression in the model group was 1.3000 +/- 0.1207, the SWE group 0. 7070 +/- 0.1215, and the CsA group 0.6700 +/- 0.0997, respectively; compared with the model group, the latter two could obviously down-regulate the expression of GrB mRNA (P<0.01) and no significant difference was found between the latter two groups (P>0.05).

CONCLUSIONSWE could alleviate the pathologic change, down-regulate the mRNA expression of myocardial GrB in allogenic ectopic transplanted myocardium of rats, it is possibly one of the factors for its antagonizing effect against reject reaction.

OBJECTIVETo compare the effects of Roux-en-Y gastric bypass (RYGBP)procedures preserving different gastric volume on blood glucose of rats with non-obese type 2 diabetes.

METHODSA total of 36 Goto-Kakizaki rats randomly underwent one of the following procedures: gastric bypass with different types of anastomosis including the Roux-en-Y of total stomach excision(n=12), the Roux-en-Y of partial stomach excision(n=12) and the Roux-en-Y of stomach preservation(n=12). Rats were observed for 24 weeks after surgery. Body weight, food intake and fasting blood glucose level were tested at 0(preoperative), 1, 3, 6, 12, 24 weeks. Hemoglobin A1c(HbA1c) level was measured at 0, 12, 24 weeks and glucose tolerance test (OGTT) was performed in conscious rats before (baseline) and then 30, 60, 120, and 180 minutes. Change of blood glucose over time was depicted. Area under curve(AUC) of glucose tolerance were calculated.

RESULTSCompared with preoperative levels, the weight and food intake of all the rats were significantly decreased at 1 week after surgery(P<0.01). At 3 weeks after operation, the weight and food intake were significantly increased compared with 1 week after operation in the Roux-en-Y of partial stomach excision and the Roux-en-Y of stomach retention(P<0.01). In the Roux-en-Y of total stomach excision, the weight and food intake were significantly lower compared with other two groups(P<0.05). At 24 weeks after operation, the levels of fasting blood glucose were (7.3 ± 1.5), (7.5 ± 2.0) and (8.3 ± 1.3) mmol/L, which were lower than the preoperative levels [(13.2 ± 1.6), (13.6 ± 2.5) and (12.9 ± 2.0) mmol/L, P<0.01] in the three groups. There were no significant differences among the three groups(P>0.05). At 24 weeks after operation, the HbA1c levels were(6.3 ± 1.3)%, (6.4 ± 2.0)% and (7.0 ± 1.3)%, which were lower than the preoperative level[(10.2 ± 2.6)%, (9.6 ± 2.5) and (9.9 ± 2.0)%, P<0.01]. There were no significant differences among the three groups(P>0.05). The trend of the glucose tolerance test and AUC were similar in the three groups after operation.

CONCLUSIONRoux-en-Y gastric bypass in non-obese diabetic rats is effective in terms of glucose control and the efficacy of gastric bypass has no obvious association with the stomach volume.

OBJECTIVETo study the antiproliferation effect on HepG2 cells and its underlying mechanism of the active chemical composition of the Viburnum Odoratissimum.

METHODS3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) reduction assay and trypan blue dye exclusion assay were used to assess the effect of vibsane-type diterpenoids on the proliferation of various tumor cells. Alterations in cell cycle and apoptosis were determined by flowcytometry. The enzymatic activity of caspase-3/7 was measured by Apo-ONE homogeneous Caspase-3/7 Assay kit.

RESULTSCompound 1 #, a vibsane-type diterpenoid, was found to significantly inhibit the growth of HepG2 cells by anticancer proliferation activity screening. It was demonstrated that the modified groups on side chain coupled to C11 site affected the cell growth-inhibition activity of compounds by structure-activity analysis. In addition, HepG2 cell line was most sensitive to compound 1 #, which induced growth arrest of HepG2 cells in a dose- and time-dependent manner. Study on the mechanisms underlying these effects indicated that compound 1 # induced significant G0/G1 phase arrest of HepG2 cells in a time- and concentration-dependent manner. Meanwhile, It was found that higher concentrations of compound (5-10 micromol/L) caused evident increase in the unmber of apoptotic cells and dose-dependent activation of caspase-3/7.

CONCLUSIONVibsane-type diterpenoids could significantly inhibit the growth of HCC HepG2 cells. Induction of cell cycle arrest and apoptosis may play important roles in their anticancer effects.
