Objective: To compare the efficacy of moxibustion with different doses for knee osteoarthritis (KOA), and explore the correlation between moxibustion dose and clinical efficacy. Methods: Sixty-eight patients with KOA who met the inclusion criteria were randomly divided into a 20-minute moxibustion group and a 40-minute moxibustion group by the random number table method, with 34 cases in each group. Dubi (ST 35), Neixiyan (EX-LE 4) and Heding (EX-LE 2) were used for moxibustion in the two groups. Each treatment lasted 20 min or 40 min for each point in the 20-minute moxibustion group and 40-minute moxibustion group, separately; the treatment was given 3 times a week and lasted for 4 weeks. The visual analog scale (VAS), Western Ontario and McMaster University osteoarthritis index (WOMAC) and traditional Chinese medicine (TCM) symptom scores were evaluated before and after treatment to compare the efficacy between different moxibustion doses for KOA. Results: After treatment, the total effective rate was 87.5％ in the 40-minute moxibustion group, versus 70.0％ in the 20-minute moxibustion group, and the difference in the total effective rate between the two groups was statistically significant (P<0.05). After treatment, the VAS scores, the total WOMAC scores and the component scores of pain, stiffness and dysfunction, and the TCM symptom scores in both groups all changed significantly when compared with those before treatment (all P<0.05). After treatment, the between-group differences in the VAS score, the total WOMAC score and the component scores of pain and dysfunction, and the TCM symptom score were statistically significant (all P<0.05), while the difference in the stiffness score in WOMAC showed no statistical significance (P>0.05). Conclusion: Either 20-minute moxibustion or 40-minute moxibustion can relieve pain, improve stiffness, dysfunction, and TCM symptoms for KOA; and 40-minute moxibustion is better in relieving pain, improving dysfunction and TCM symptoms.

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

ObjectiveTo investigate the value of a digital three-dimensional reconstruction technique in the treatment of hepatic alveolar echinococcosis (HAE).MethodsThe computed tomography scan data for 13 patients with HAE who were admitted to the First Affiliated Hospital of Xinjiang Medical University from February 2011 to October 2011 were reconstructed and analyzed by a three-dimensional reconstruction system to assess resectability,and to facilitate surgical planning and individualized virtual surgery.The results of preoperative analysis were compared with the results of actual operations.ResultsThe three-dimensional models of the liver were reconstructed successfully,and intrahepatie lesions and vessels were clearly displayed.One patient received an autologous liver transplantation,10 underwent hepatectomy,and 2 received percutaneous transhepatic cholangial drainage.Virtual operation planning was carried out for 11 patients using the three-dimensional reconstruction system.The mean volume of the liver to be resected was predicted to be 920 ml (range,339-2678 ml),and the mean percentage of liver to be resected to the total liver volume was predicted to be 45％ ( range,23％ -68％ ).The mean volume o[ the actual liver resection was 834 ml (range,315-2250 m[),and the mean percentage of actual liver resected to the total liver volume was 42％ (range,22％ -70％ ),which was consistent with the results of preoperative three-dimensional reconstruction.All patients were followed up for 2-8 months,and no severe complications such as liver failure,hemorrhage and bile leakage were detected.ConclusionDigital three-dimen-sional reconstruction is helpful in the diagnosis and treatment of HAE and effectively reduces surgical risks.
