BACKGROUND:There is no doubt that animal model of fracture is the basis of fracture healing research.The fracture animal mode is divided into open osteotomy model and closed fracture model.There is no research about the difference between two kinds of fracture rat models.OBJECTIVE:To compare the modeling process between open osteotomy model and closed fracture model in rats,and to compare fracture healing using radiograph.DESIGN,TIME AND SETTING:The randomized,controlled animal experiment was performed at the Laboratory of Department of Orthopaedics,Second Affiliated Hospital,Soochow University from January to May 2007.MATERIALS:A total of 40 SPF male Sprague Dawley rats,weighing(220?30) g,were randomly divided into an open osteotomy model group and a closed fracture model group,with 20 rats for each group.Electric swing saw was a kind of self-made percussion device for closed fracture models.METHODS:All rats in the open osteotomy model group received open osteotomy to create transverse fracture of the middle femur,and fixed using Kirschner wire.Rats in the closed fracture model group received retrograde Kirschner wire fixation,and midshaft femoral closed fracture induced by model establishment stent.MAIN OUTCOME MEASURES:Mean model establishment time;Successful rate of model establishment;Radiography of fracture healing at 2,3,4 and 8 weeks after surgery.RESULTS:Success rate of open osteotomy model establishment was 90%.Average modeling time was 17 minutes.Rate of malunion and nonunion was 40%.Successful rate of each closed fracture models was 85%,with average modeling time was 12 minutes.There was no malunion and nonunion.At 2,3 and 4 weeks after surgery,X-ray score was lower in the open osteotomy model group compared with the closed fracture model group(P 0.05).CONCLUSION:Model establishment of open osteotomy takes a longer time,with a high rate of malunion and nonunion.In near future or medium-term,fracture healing is significantly lagged.Thus,open osteotomy is not suitable for the study of early or medium-term fracture healing.

Objective To observe the clinical efficacy of bloodletting and cupping at Fengchi (GB 20) plus acupuncture in treating peripheral facial paralysis in acute stage.Method Sixty patients with peripheral facial paralysis in acute stage (disease duration ≤7 d) were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by bloodletting and cupping at Fengchi (GB 20) plus acupuncture, while the control group was treated with ordinary acupuncture. The two groups were treated once a day, 5 times a week, 2 weeks as a treatment course and 3 treatment courses in total. The House-Brackmann (H-B) facial nerve grading system was observed before and after the intervention, and the clinical efficacies in the two groups were compared. Result The total effective rate was 96.7% in the treatment group versus 93.3% in the control group, and the difference was not statistically significant (P>0.05). There were statistically significant differences in the H-B score between the two groups respectively after 2 and 3 treatment courses (P<0.05).Conclusion Bloodletting and cupping at Fengchi (GB 20) plus acupuncture is an effective approach in treating peripheral facial paralysis in acute stage.

BACKGROUND:There were stil lacking related clinical researches in the aspects of whether the total blood loss and hidden blood loss were connected with pathogenesis, whether the total blood loss and hidden blood loss were different among the patients who conducted total hip arthroplasty under different pathogenesis, and whether the preoperative intervention should be conducted for a particular cause? OBJECTIVE:To compare and analyze the hidden blood loss of patients with hip osteoarthritis and femoral neck fracture after total hip replacement. METHODS:The clinical data of 150 patients who received the unilateral total hip arthroplasty treatment from June 2013 to January 2015 were colected and analyzed, including 54 patients with hip osteoarthritis (30 male cases and 24 female cases ), 96 patients with femoral neck fracture (41 male cases and 55 female cases). The pre-and post-operative blood routine and intro-and post-operative blood loss and transfusion were recorded, and hidden blood loss during pen-operation period was evaluated. RESULTS AND CONCLUSION:Total blood loss was (1 616±216) mL, hidden blood loss was (699±102) mL, and hidden blood loss accounted for 43.3% of the total blood loss. The total blood loss was (1 742±254) mL in the hip osteoarthritis group, hidden blood loss was (758±127) mL, hidden blood loss accounted for 44.6% of the total blood loss; The average total blood loss was (1 470±189) mL in the femoral neck fracture group, hidden blood loss was (625±98) mL, hidden blood loss accounts for 42.1% of the total blood loss. The total blood loss and hidden blood loss in hip osteoarthritis group were significantly higher than those in the femoral neck fracture group (P< 0.05). However, there was no significant difference on the hidden blood loss accounts for the proportion of the total blood loss between two groups (P=0.419 3). These results suggest that the total blood loss and hidden blood loss are different for the patients who underwent total hip arthroplasty in the premise of both pathogenesis. Therefore, before the total hip arthroplasty, we should fuly take into account the primary cause of patients and estimate the total blood loss and hidden blood loss, so as to take appropriate preventive measures in time to ensure the safety of the replacement process.

Objective:To observe the clinical effect of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of dorsal wrist ganglion (DWG). Methods:A total of 63 patients with DWG were randomized into a treatment group (n=32) and a control group (n=31). Cases in the control group were treated with fire needle therapy. Based on the therapy given to the control group, cases in the treatment group were additionally given wheat grain-sized cone moxibustion therapy. Then the therapeutic efficacies and recurrence rate were evaluated. Results:After treatment, the overall effective rate was 93.8% in the treatment group, versus 77.4% in the control group, and the between-group comparison showed a statistical significance (P<0.05); 6 months after the treatment, the recurrence rate in the treatment group was obviously lower than that in the control group (P<0.05). Conclusion:The long-term and short-term effects of wheat grain-sized cone moxibustion combined with fire needle therapy in the treatment of DWG are better than those of fire needle therapy alone, and therefore, worth popularizing.

Undifferentiated and differentiated 3T3-L1 adipocytes were treated with 100 ng/ml tumor necrosis factor-?(TNF-?),and peroxisome proliferator-activated receptor-?2 (PPAR-?2) mRNA expression and adiponectin secretion in cultured cells were measured.The results showed that TNF-?suppressed PPAR-?2 mRNA expression and adiponeetin secretion in 3T3-L1 adipocytes (P

Lung cancer is the leading cause of death in malignant tumors. Surgery is one of the main treatments for early stage lung cancer. Idiopathic pulmonary fibrosis (IPF), one of the most common interstitial lung disease, is a chronic, progressive lung disease, characterized by insidious onset and progressive deterioration. It is reported that there are common pathways in idiopathic pulmonary fibrosis and lung cancer, and patients with IPF have a higher risk of lung cancer than the general population, whose prevalence was 3.34 times than that of the general population. The incidence of acute exacerbations of IPF and postoperative mortality was significantly higher in lung cancer patients complicated with IPF than those without IPF. The long-term outcomes of patients with IPF are dramatically worse than those without IPF. It was concluded that lobectomy has been still the standard surgical procedure for such patients, but sublobectomy should be taken as potential alternative choice for patients with high risk after preoperative evaluation. Moreover, further studies should be conducted on the prevention and treatment of acute exacerbation of IPF after surgery.

Objective:To investigate the effects of moxibustion on the serum metabolism in healthy human body based on the 1H nuclear magnetic resonance (1H NMR) metabolomics technology, and to find the differences in metabolites, as well as to elucidate the effects of moxibustion on healthy human body from the viewpoint of global metabolism. Methods:Sixty subjects of healthy young men from the enrolled students were randomly divided into a moxibustion group and a control group using random number table, with 30 cases in each group. Subjects in the moxibustion group accepted mild moxibustion on the right Zusanli (ST 36), once a day, 15 min for each time, and continuous treatment for 10 d; those in the control group did not receive any intervention. There were 28 cases in the moxibustion group and 23 cases in the control group after interventions. On the 1st day, 5th day and 10th day of the intervention, serum samples were collected from subjects of the two groups, and metabolic spectra were obtained by the1H NMR technology. Results: Before and after the intervention, serum1H NMR of the moxibustion group was significantly different, while the difference was insignificant in the control group. Metabolite changes in the moxibustion group were mainly in low density lipoprotein (LDL)/very low density lipoprotein (VLDL), valine, isoleucine, leucine, lactic acid, glutamine, citric acid, polyunsaturated fatty acids, creatine, glycine, glycerol, glucose, tyrosine, histidine, formic acid, alanine, lysine, acetic acid, and glutamic acid. Conclusion:Moxibustion can cause changes of serum metabolic patterns in healthy human by influencing the concentrations of branched-chain amino acids, polyunsaturated fatty acids, and other metabolites to strengthen body's metabolisms of amino acids and fatty acid.
