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.

The aim of this paper is to apply Raman spectroscopy technique to develop rapid quantitative models for five kinds of Traditional Chinese Medicine containing CaCO3. In the experiment, Raman spectras of 67 batch of sample including Otolithum Sciaenae, Galaxeae Os, Ophicalcitum, Calcite, Stalactite and their mixture which had different content of CaCO3 were collected, and the quantitative models were established by using an improved siPLS to optimize the characteristic spectral bands and using the CaCO3 contents which were measured by EDTA titration method as references. Compared with the results by EDTA titration, the established quantitative model for CaCO, content showed a prediction result that the average relative deviation of the prediction results is 2. 71% and the average recovery rate was 100.46%, when the content is between 0.465 4-0.999 7, and when the characteristic spectral bands of 1 290-1 280, 730-714, 700-690, 660-650, 465-460, 455-445, 405-385 cm(-1) had been optimized. The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

Objective:To observe the effect of herbal cake-partitioned moxibustion on the expressions of mitogen-activated protein kinase (MEK1/2) and extracellular regulatory protein kinase (ERK1/2) in gastric tissues of rats with spleen deficiency syndrome, and to explore the possible mechanisms of herbal cake-partitioned moxibustion in treating spleen deficiency syndrome. Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group (group A), a model group (group B), a ranitidine group (group C), and a herbal cake-partitioned moxibustion group (group D) by random digit, 15 rats in each group. Rat models of spleen deficiency syndrome were made by intragastric administration of 4℃ 200% concentrated Da Huang (Radix et Rhizoma Rhei). After successful modeling, the rats in group C were treated with 25 mg/(kg·bw) ranitidine by intragastric adminstration and rats in group D were treated with herbal cake-partitioned moxibustion at Zusanli (ST 36) and Zhongwan (CV 12), for 8 d. Excepted for rats in group A, all the other rats were treated with indomethacin at 5 mg/(kg·bw) at 8:00 a.m. on the second day after finishing all the intervention and sacrificed 7 h later to isolate the stomach. Histopathological changes of the gastric tissues were observed under light microscope after hematoxylin-eosin (HE) staining. The protein expressions of MEK1/2 and ERK1/2 in the gastric tissues were detected by immunohistochemistry. Results:After intervention, the gastric mucosal injury in group B was significantly severer than that in group A, with large breakage and ablating; the damage of gastric mucosa was decreased in group C compared with group B; the gastric mucosal surface remained relatively complete, and the status of breakage and ablating was significantly improved. After intervention, compared with group A, the protein expressions of MEK1/2 and ERK1/2 in gastric tissues of the other groups were significantly higher (P<0.01). Compared with group B, the protein expressions of MEK1/2 and ERK1/2 in group C and D were significantly higher (allP<0.01). Compared with group C, the protein expressions of MEK1/2 and ERK1/2 in group D were significantly higher (P<0.01). Conclusion: Herbal cake-partitioned moxibustion promotes the repair of gastric mucosa in rats with spleen deficiency syndrome, via improving protein expressions of MEK1/2 and ERK1/2 in gastric tissues, as well as activating MEK/ERK signaling pathway.

OBJECTIVETo prepare the superparamagnetic iron oxide (SPIO)-labeled antisense oligodeoxynucleotide (ASODN) probe and evaluate the application of this probe in cellular magnetic resonance imaging (MRI).
METHODSWe prepared the SPIO-labeled ASODN probe using chemical cross linking method to conjugate SPIO to ASODN, detected its configuration by atomic force microscopy, determined the conjugating rate and biology activation by high performance liquid chromatography, and detected the stability by polyacrylamide gel electrophoresis. After that, we transfected the SK-Br3 oncocytes which had over-expression of the c-erbB2 oncogene by this probes, observed the intracellular iron distribution by optical microscope, measured iron content by atomic absorption spectroscopy, and observed the signal change by MRI.
RESULTSAtomic force microscope showed that the SPIO-labeled ASODN probe was mostly spherical and well-distributed, with a diameter of 25-40 nm and a conjugating rate of 100%. This probe had inhered biological activity and stability. In addition, light microscopy revealed an intracellular uptake of iron oxides in the transfected SK-Br3 oncocyte, and the iron content of the group of transfected SK-Br3 oncocytes was significantly higher than those of other contrast groups (all P < 0.01). MRI showed that transfected SK-Br3 oncocyte had the lowest signal among all other cells (all P < 0.05).
CONCLUSIONSWe prepared the SPIO-labeled ASODN probe successfully. It can effectively transfect SK-Br3 oncocyte and enter SK-Br3 oncocyte, and thus reduce the signal intension in MRI.

OBJECTIVETo observe the clinical efficacy of acupuncture combined with massage on infiltrative exophthalmos so as to provide a more effective treatment for infiltrative exophthalmos in hyperthyroidism.
METHODSForty-five cases of infiltrative exophthalmos were randomly divided into an acupuncture massage group (25 cases) and a western medicine group (20 cases). In acupuncture massage group, acupuncture was applied mainly at Jingming (BL 1), Qiuhou (EX-HN 7), Chengqi (ST 1) and Shangming (Extra); and massage was applied in combination on the back of the neck and the local points around the orbit. In western medicine group, Dexamethasone and Methotrexate were used for intravenous infusion, and Prednisone was for oral administration. The exophthalmos extent and clinical efficacy were compared between two groups.
RESULTSBefore and after the treatment, the exophthalmos extents were (20.27 +/- 1.22) mm and (18.11 +/- 0.87) mm in acupuncture massage group and were (20.34 +/- 1.20) mm and (19.47 +/- 1.11) mm in western medicine group separately, indicating remarkable improvement in two groups (both P < 0.01). The improvement in acupuncture massage group was superior remarkably to that in western medicine group (P < 0.01). The total effective rate (83.3%, 40/48) in acupuncture massage group was superior to that (53.8%, 21/39) in western medicine group, and with less adverse reaction.
CONCLUSIONAcupuncture combined with acupoint massage is an advanced therapy and has definite efficacy on infiltrative exophthalmos, which is superior to the conventional treatment in western medicine.

The medical CT scanner is rapidly evolving from the fan-beam mode to the cone-beam geometry mode. In this paper, a new cone-beam pseudo Lambda tomography was proposed based on the Noo's fan beam super-short scan formula and FDK framework. The proposed pseudo-LT algorithm, which avoids the computation of any PI line and any differential operation, has a significant practical implementation, thus leading to the images with quality improvement and reduced artifacts. The results in the simulation studies confirm the observation that the new algorithm can improve the image resolution over the traditional algorithms with noise projection data.
