The method of flying through the air is a qi-promoting and qi-circulating technique commonly used in clinical acupuncture. It includes four methods: the blue dragon wagging its tail, the white tiger shaking its head, the green turtle probing the cave and the red phoenix winging to the source and functions to circulate bodily meridian qi. The method of flying through the air was firstrecorded in Golden needle Fu. Later and modern doctors developed it on the basis of Golden needle Fu. This article straightens up the historical origin and development of four methods of flying through the air.

Objective To investigate the potential role of human cytomegalovirus lower matrix phosphoprotein 65 (HCMV pp65) in murine systemic lupus erythematosus (SLE).Methods The prokaryotic vector pET-28b and eukaryotic vector pcDNA 3.0 were constructed to express the HCMV pp65 protein.All the C57BL/6 mice were inoculated with pp65 eukaryotic vector intramuscularly five times at 2-week intervals and then were bled via the retro-orbital vein.Subsequently,indirect ELISA was used to evaluate the concentration of anti-pp65 IgG,anti-dsDNA and ANA.At the same time,IL-1 b,IL-6,and TNF-α were determined by competitive ELISA.Results The early onset of autoantibodies and an overexpression of IL-6 were observed in immunized male C57BL/6 mice.Conclusion HCMV pp65 triggers the deregulation of humoral immunity in C57BL/6 mice,which indicates that the immune responses induced by HCMV pp65 may be involved in the development of SLE.

We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy between the Tc-99m TRODAT-1 and Tc-99m ECD scan provides insight into the imbalance between direct and indirect circuits along the nigrostriatal pathway, as the fundamental genesis of HGHC. Furthermore, the hyperperfusion at the left thalamus represents thalamic disinhibition secondary to loss of pallidal negative control, which ultimately leads to HGHC through re-entrant outflow to the motor cortex.

BACKGROUND:The number of elderly patients with hip fracture is huge, and this population mainly combines with a variety of internal diseases. The general condition was bad. Compared to total hip arthroplasty, bipolar hemiarthroplasty can shorten operation time, reduce the time of anesthesia and improve surgical safety, but the operation using which fixation mode is always controversial.
OBJECTIVE:To compare the safety and curative effects of bipolar hemiarthroplasty with cementless or cement femoral stem prosthesis in elderly patients with osteoporotic complex hip fracture.
METHODS:From June 2007 to June 2010, 198 elderly patients with osteoporotic hip fracture aged more than 75 years old, who were treated with bipolar hemiarthroplasty in the People’s Hospital of Xinjiang Uygur Autonomous Region, China, were enroled in this study. Al patients were divided into cementless group (n=69) and cement group (n=129) according to the type of prognosis. Osteoporosis was treated conventionaly in both groups after replacement. Operation time, intraoperative blood loss, incidence of postoperative hip pain, out of bed activity time post surgery, Harris scores of last folow-up and loosening rate of the prognosis were compared between the two groups.
RESULTS AND CONCLUSION:176 of above 198 cases were folowed up for 48 to 84 months, including 122 in the cement group and 54 in the cementless group. Operation time was longer in the cement group than in the cementless group, but out of bed time was earlier in the cement group than in the cementless group post surgery, and there were significant differences (P < 0.05). The incidences of loosening and hip pain were more in the cement group than in the cementless group post surgery (P < 0.05). No significant difference in intraoperative blood loss and Harris scores of last folow-up was detected between the two groups (P > 0.05). The incidences of loosening rate were 5% and 4% in the cement and cementless groups, respectively, which showed significant differences (P< 0.05). These results indicate that bipolar hemiarthroplasty with or without cement for osteoporotic hip fracture in the elderly can obtain good middle- and long-term effects. Bipolar hemiarthroplasty with cement can reduce the out of bed time, but operation time was longer, and incidences of hip pain and loosening were higher in cement prosthesis than in cementless prosthesis.

Objective To evaluate the effects of four types of variance reduction techniques ( ring counter grid, high electron cutoff energy, termination of electron tracking in some structures, and emission direction?biased sampling of source) on the efficiency and accuracy of Monte Carlo simulation for the single source channel of the Leksell Gamma Knife. Methods The single source channel of the Leksell Gamma Knife was modeled using Monte Carlo software MCNP . Four types of variance reduction techniques were used to simulate the dose distribution in the water?like phantom. The computation efficiency and simulation result were compared between the four techniques. Results All techniques substantially improved the computation efficiency and had little effect on the accuracy of the simulation ( relative error less than 2. 5%) . However, if the electron cutoff energy was above 50 keV, the simulation became quite inaccurate due to neglect of the scattering of high?energy electrons and their dosimetric contribution to the penumbra. When the scattering of high?energy electrons and their dosimetric contribution to the penumbra were ignored, the dose to the Profile platform was overestimated and the dose to the penumbra was underestimated. Conclusions Rational use of variance reduction techniques can substantially improve the efficiency of Monte Carlo simulation for the single source channel of the Leksell Gamma Knife. However, the impact of variance reduction techniques on the accuracy of the simulation should be carefully evaluated.

Objective To develop whole breast irradiation with volumetric-modulated arc therapy (VMAT)-based hybrid intensity-modulated radiotherapy (IMRT) after breast conserving surgery for breast cancer,and to evaluate its value in clinical application.Methods Ten patients with breast cancer undergoing breast conserving surgery were enrolled.Two radiotherapy plans were designed based on hybrid fixed-beam IMRT/IMRT technique and hybrid VMAT/IMRT technique,respectively.One group received whole breast irradiation with a prescribed dose of 50 Gy in 25 fractions.The other group received whole breast irradiation with a prescribed dose of 50 Gy in 25 fractions,as well as simultaneous integrated boost to the tumor bed with 60 Gy in 25 fractions.The dosimetric parameters and delivery efficiency were compared between the two plans using paired t test.Results For patients treated with whole breast irradiation alone,there were no significant differences in conformity index and homogeneity index of target volume between the two plans (P=0.866,0.056);however,compared with the hybrid fixed-beam IMRT/IMRT technique,the hybrid VMAT/IMRT technique significantly increased the doses to organs at risk (OARs) and the number of monitor units (MUs) in the intensity-modulated field (P=0.000-0.050,P=0.002).For patients treated with whole breast irradiation with a simultaneous integrated boost to the tumor bed;however,the hybrid VMAT/IMRT technique significantly reduced the doses to the lung and spinal cord,number of MUs in intensity-modulated field,and delivery time compared with the hybrid fixed-beam IMRT/IMRT technique (P=0.004,0.001,0.000,0.000).Conclusions For patients treated with whole breast irradiation with a simultaneous integrated boost to the tumor bed,the hybrid VMAT/IMRT technique is highly promising for clinical application due to better OAR sparing and higher delivery efficiency.

Based on the structure and function of acupoint and in association of the definition and principle of sensor, the acupoint is the sensitive element, being sensitive to the physical stimulation with acupuncture and moxibustion and sensitively responded to the disorders; the acupoint is the sensing element, transforming the changes of the acupoint information via the complicated internet conduction, integration and regulation, so as to generate the effects on organic body; the acupoint is the conversion element, transforming every irritation into the bioelectric signal or optical signal so that the organic body could recognize it. Therefore, the acupoint is regarded as the sensor of information in the organic body.

OBJECTIVETo observe the metabolic, regulatory and anti-oxidative effects of modified Bushen Huoxue Decoction (BSHXD), a Chinese herbal medicine for kidney (Shen)-reinforcement and blood-activation, on an osteoarthritis (OA) rabbit model.

METHODSA rabbit model for knee joint OA was established by the classic Hulth's method. The OA model rabbits were randomized into 5 groups: the model control group, the positive control group treated with glucosamine sulfate, and the three BSHXD treated groups treated respectively with low, moderate, and high doses of BSHXD. In addition, a normal control group and a sham-operated group were set up. Experimental animals were sacrificed after a 7-week treatment, and pathological changes in cartilaginous tissue were estimated using the Mankin criteria. Hydroxyproline (Hyp) and malonaldehyde (MDA) contents in blood serum and urine, as well as superoxide dismutase (SOD) activity and nitric oxide (NO) content in blood serum and knee joint synovial homogenates were detected.

RESULTSMankin scoring showed insignificant statistical differences between the various treatment groups (P >0.05), but all were better than the model control group (P <0.05). Serum and urinary contents of Hyp and MDA as well as serum and synovial levels of NO were significantly lower, but the SOD activity in blood serum and synovial tissue was higher in the BSHXD treated groups than in the model group P <0.01); the effect of BSHXD was dose-dependent to some extent.

CONCLUSIONThe modified BSHXD shows an effect of improving cartilage metabolism in experimental rabbits with OA, and possesses osteo-chondric protective effects in antagonizing peroxidation injury.

OBJECTIVETo study the clinical effectiveness of implanting miniscrew serving as anchorage instead of molars in treating maxillary dental arch crowding and protrusive patients mandibular molars complete missing.

METHODSEight adult patients aged from 22 to 38, whose maxillary dental arch were crowding and protrusion, with mandibular molars missing were chosed. At the missing side, a miniscrew was implanted on the buccal surface, 11-13 mm away from the distal end of the second premolar. After implanting, a self-made miniscrew traction cap was attached to its supergingival section by keyway retention. Premolars and anterior teeth were tracted in turn to distal end. Intermaxillary traction II was made necessarily on the traction cap.

RESULTSSuccessful results were acquired after treating together with normal overbite, overjet and right occlusion relation. It took 24 months in the longest course, 15 months in the shortest course and 20.8 months on average.

CONCLUSIONThe implanting miniscrew anchorages could be used in maxillary dental arch crowding and protrusive patients with single molars complete missing.
