ObjectiveTo compare the diagnostic efficiency of 18F- FDG coincidence SPECT/CT and 99Tcm- MDP whole body bone scan (WBBS) in detecting malignancy.MethodsA total of 71 cases (male 45,female 26,mean age 59.2 ± 15.4 years) with clinically confirmed malignancy underwent both 99TcmMDP WBBS and 18F-FDG coincidence imaging within three weeks.The sensitivity,specificity,accuracy,positive and negative prediction value of these two imaging methods in detecting bone metastases were compared based on the results from pathology or clinical follow-up.x2test was used for data analysis.ResultsA total of 350 lesions (including primary,second malignancy and benign disease) in 71 patients were eval-uated.81.7％ (286/350) malignant lesions were identified by either 99Tcm-MDP WBBS (209/350,59.7％ ) or 18F-FDG coincidence imaging ( 141/350,40.3％ ) (x2 =25.65,P ＜ 0.01 ).The imaging findings of osteoblastic,osteolytic,mixed types of bone metastases by99Tcm-MDP WBBS and 18F-FDG coincidence imaging were significantly different (x2 =20.78,2.89 and 9.94,all P ＜ 0.05 ).The sensitivity,specificity,accuracy,false-positive,false-negative,positive and negative predictive values for detecting bone metastases by 18 F-FDG coincidence study and 99Tcm-MDP WBBS were as follows:11.72％ ( 15/128),91.67％(22/24),24.34％ (37/152),8.33％ (2/24),88.28％ (113/128),88.24％ (15/17),16.30％ (22/135) ; and 53.91％ (69/128),75.00％ ( 18/24),57.24％ (87/152),25.00％ (6/24),46.09％ (59/128),92.00％ (69/75),23.38％ ( 18/77 ).The sensitivity,accuracy,false-negative,positive-predicting value of the two methods had been significant different (x2 =32.70- 46.21,all P ＜ 0.01 ).When two methods were combined,the diagnostic efficiency could been improved.ConclusionThe 99Tcm-MDP WBBS and 18F-FDG coincidence imaging has a complementary role in detecting bone metastases.

The ideal treatment and recovery of osteoarticular injury remain to be resolved. Small intestinal submucosa (SIS), a naturally-occurring decellularized extracellular matrix, has been recognized as an ideal scaffold for tissue engineering and widely used in repairing various tissues and organs. Nowadays its application has also been gradually increased in the field of orthopedics. We reviewed laboratorial studies and clinical trails about the application of SIS in bone and joint repair, aiming to evaluate its effects on the repair of bone, cartilage, meniscus, ligament and tendon. SIS has showed promising results in repairing bone, meniscus, ligament or tendon. However, additional studies will be required to further evaluate its effects on articular cartilage and tendon-bone healing. How to optimize SIS material,is also a focused problem concerned with making SIS a potential therapeutic option with high value for orthopedic tissue repair.

Objective To evaluate distribution features of disrupted carotid plaque. Methods Forty-three subjects with duplex ultrasound evidence of 50% to 99% stenosis were retrospectively analyzed. Plaques were categorized as disrupted if there was MRI evidence of fibrous cap rupture. Quantity measured areas of the lumen (LA), wall (WA), and plaque components. The morphological parameters used were total vessel area, vessel burden index, eccentricity index. Mann-Whitney test and Chi-square test appropriate used SPSS (v. 12.0 ). Results There were 17 disrupted and 26 undisrupted lesions identified for comparison. Disrupted plaques showed a predominance of longer longitudinal length of large lip nucleus along the vessel wall (6 mm vs. 0 mm, U = 126, P <0.05 ), a large vessel burden (0.67 vs. 0.59, U =105, P <0.05), and high prevalence of thrombus (82.4% vs. 42.3 %, U = 132,P <0.05). In addition, disrupted plaques showed a different pattern of plaque distribution, having a more eccentric position of the lumen (3.68 vs. 2.79, U = 126, P < 0.05 ), a smaller lumen area (23.97 mm2 vs. 30. 18 mm2, U = 138, P<0.05) and a longer segment of stenosis when compared with the intact plaques. Conclusions Disrupted plaques have significantly different characteristics in terms of both axial and longitudinal distribution. A combination of multi-plane and multi-contrast high resolution MRI may provide valuable information about overall lesion morphology and its association to vulnerability.

OBJECTIVE To assess the efficancy of Yangxue Qingnao granules on simvastatin-induced vascular injury model in zebrafish. METHODS Since statins can inhibit vascular development in zebrafish,in this study,we developed a novel animal model using 1 to 3 day post-fertilization larval zebrafish by optimizing the doses and duration of simvastatin exposure.Five pro-angiogenic drugs with a variety of mechanisms were tested to validate the newly developed zebrafish model. Zebrafish was treated with different concentration of Yangxue Qingnao granules( 62.5,125 and 250 μg·mL-1)for 2 d then tested for the area of subintestinal vein vessels. RESULTS Vascular regeneration promoting effect of five pro-angiogenic drugs (calycosin, astragaloside, chlorogenic acid, ferulic acid and Panax Notoginseng Saponins)were 8-48%,24-51%,35-58%,28-75% and 37-69%,respectively.In 62.5,125 and 250 μg·mL-1Yangxue Qingnao granules group,vascular regeneration promoting effect were 21% (P>0.05), 84%(P<0.01) and 53%(P<0.01). CONCLUSION Our results demonstrate that the zebrafish vascular injury model validated in this study could be used for in vivo angiogenesis studies and drug screening and for assessing pro-angiogenic drugs with different mechanisms.Yangxue Qingnao granules could promote the vascular regeneration in zebrafish.

OBJECTIVETo evaluate clinical efficacy of electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery on postoperative pain and discomforts in patients with mixed hemorrhoids.

METHODSOne hundred and twenty cases of mixed hemorrhoids who received Milligan-Morgan operation were randomly divided into an electroacupuncture group, a sham electroacupuncture group and a blank group, 40 cases in each one. At the same time of basic treatment, the electroacupuncture was applied at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery in the electroacupuncture group, while shallow needling without electrical stimulation at sham acupoint (1 cm next to acupoint) was applied 30 min before surgery in the sham electroacupuncture group, while no treatment was given before the surgery in the blank group. The total dose of painkillers in the first 24 h after operation, the number of cases who received additional anesthetic in the operation, the self-score of most severity pain in the first 24 h after operation and sleeping time in the night of surgery were observed.

RESULTSThe differences of the numbers of cases who received additional anesthetic in the operation had no statistical significance among the three groups (all P > 0.05), but compared with the sham electroacupuncture group and blank group, the total dose of painkillers in the first 24 h after operation was reduced in the electroacupuncture group [(2.43 +/- 1.08) tablets vs (3.23 +/- 1.33) tablets, (3.10 +/- 1.22) tablets], and the score of most severity pain was also decreased (6.65 +/- 1.00 vs 7.48 +/- 0.96, 7.25 +/- 1.19), besides, the sleeping time in the night of surgery was increased [(220.63 +/- 85.50) min vs (162.00 +/- 92.69) min, (151.50 +/- 80.01) min, all P < 0.05].

CONCLUSIONThe electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery has effects of preemptive analgesia on postoperative pain for patients with mixed hemorrhoids.

OBJECTIVETo explore the clinical effects and significances of a cervical anterior Hybrid technique with posterior longitudinal ligament retained in treating cervical spondylosis.

METHODSThe clinical data of 138 patients with cervical spondylosis underwent cervical anterior Hybrid surgery were retrospectively analyzed from March 2009 to March 2013. There were 52 males and 86 females,the age ranged from 36 to 58 years old with an average of 45.3 years. Course of disease was from 3 to 16 months. Cervical spondylosis classification included 22 cases with nerve root type, 68 cases with myelopathic type, 48 cases with mixed type. All patients were treated with the primary Hybrid surgery and their cervical posterior longitudinal ligaments were retained in anterior decompression. JOA score and image examination were used to evaluate clinical effect, and image examination included range of motion of the replacement segment, range of motion of the whole cervical spine, the sagittal diameter of the spinal cord before and after operation.

RESULTSAll operations were successful and operation time was 60 to 125 min (averaged 90.6 min), perioperative bleeding was 10 to 60 ml (averaged 30.1 ml). All patients were followed up from 12 to 48 months with an average of 22.2 months. All pathological segments obtained fully decompression, reserved posterior longitudinal ligament had no obvious hypertrophy, proliferation and calcification. The prosthesis had good location and the incision healed well without complications. Upper limbs root symptoms were completely relieved in the patients with cervical spondylotic radiculopathy, muscle strengths and sensations got different recovery in the patients with cervical spondylotic myelopathy. JOA score was increased from preoperative 8.62±1.22 to final follow-up 14.26±1.47 (P<0.05). Artificial intervertebral discs were stabilized in the patients, the replacement segment and range of motion of whole cervical spine were respectively (14.2± 5.6)° and (33.8±10.3)°, there was no significant differences between preoperative and postoperative (P>0.05). Spinal cord sagittal diameter was increased from preoperative (5.2±1.3) mm to postoperative (8.8±0.5) mm (P<0.05).

CONCLUSIONAnterior cervical Hybrid surgery with posterior longitudinal ligament retained can achieve fully decompression and good clinical efficacy, we recommend retaining the normal posterior longitudinal ligament in surgery as complete as possible.

The research aimed to investigate the therapeutic effects and mechanisms of Opuntia dillenii Haw polysaccharide (OPS) on atherosclerosis of rats. First atherosclerotic rat models were established by high-fat and high-calcium diet. Thirty days later, the rats were treated with low dosage of OPS (0.2 g x kg(-1) x d(-1)) or high dosage of OPS (0.4 g x kg(-1) x d(-1)) by intraperitoneal injection for 60 days continuously. At the end of treatment, thoracic aorta rings were prepared and vasorelaxation of rat thoracic aorta in different experiment groups were determined by using 620M multi wire myograph system in vitro. Blood and livers of rats were collected. Then plasma levels of total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) of rats were separately determined using whole automatic biochemical analyzer; protein level of hepatic apolipoprotein B (ApoB) and that of hepatic diglyceride acyltransferase (Dgat1) were measured by Western Blot technique. Results showed that the ability of rat thoracic aorta to relax decreased markedly in the model group compared with that in the normal group, and significant differences existed in vasorelaxation ratios induced by different concentrations of carbamylcholine chloride (Carb) between these two groups (P < 0.01). After OPS treatment, the ability of rat thoracic aorta to relax improved markedly, the vasorelaxation ratios induced by Carb at 5 and 10 μmol x L(-1) were respectively 0.34 ± 0.08 and 0.62 ± 0.15 in the group treated with low dosage of OPS, while the ratios induced by Carb at 1 and 5 μmol x L(-1) were respectively 0.54 ± 0.08 and 0.98 ± 0.02 in the group treated with high dosage of OPS, which were all significantly different with those in the model group (P < 0.01). Plasma contents of TC, TG and LDL reduced significantly by the treatments both with low and high dosages of OPS compared with those in the model group (P < 0.01). Protein level of hepatic ApoB and that of hepatic Dgat1 decreased significantly after the treatment with high dosage of OPS compared with those in the model group (P < 0.01). These results indicate that OPS can markedly improve the vasorelaxation of thoracic aorta of atherosclerotic rats and has significant anti-atherosclerotic effect; inhibiting the expression of ApoB and Dgat1 and thus decreasing the amounts of TC, LDL and TG serving as one of the molecular mechanisms of its antiatherosclerosis effect.

OBJECTIVETo observe the protective effect of active fractions of Huanglian Jiedu Decoction (HJD) on primary cortical neuron injury after oxygen-glucose deprivation (OGD)/reperfusion (R) injury. Methods Using macroporous resin method, HJDFE30, HJDFE50, HJDFE75, and HJDFE95 with 30%, 50%, 75%, and 95% alcohol were respectively prepared. Then the content of active components in different HJD fractions was determined with reverse phase high-performance liquid chromatography (RP-HPLC). The OGD/R injury model was induced by sodium dithionite on primary cortical neurons in neonate rats. MTT assay was used to observe the effect of four fractions (HJDFE30, HJDFE50, HJDFE75, and HJDFE95) and seven index components of HJD on the neuron viability.

RESULTSRP-HPLC showed active component(s) contained in HJDFE30 was geniposide; baicalin, palmatine, berberine, and wogonside contained in HJDFE50; baicalin, berberine, baicalein, and wogonin contained in HJDFE75. The neuron viability was decreased after OGD for 20 min and reperfusion for 1 h, (P <0. 01), and significantly increased after administered with HJD, HJDFE30, HJDFE50, and HJDFE75 (P <0. 05, P <0. 01). Geniposide, baicalin, baicalein, palmatine, wogonside, and wogonin could increase the cortical neuron viability (P <0. 05, P <0. 01).

CONCLUSIONSHJDFE30, HJDFE50, and HJDFE75, as active fractions of HJD, had protective effect on primary cortical neuron injury after OGD/R. Furthermore, geniposide, baicalin, and baicalein were main active components of HJD.
