OBJECTIVETo establish a protocol of automated synthesis of 1-(2-chlorophenyl)-N-[(11)C]methyl-N-(1-methylpropyl)-3-isoquinoline carboxamide ((11)C-PK11195) as the positron-emitter-labeled ligand for peripheral benzodiazepine receptor (PBR) using a commercial synthesizer and explore the quality control methods for the resulting product.
METHODS(11)C-methyl iodide ((11)C-CH(3)I) was synthesized via liquid-phase distillation approach using a (11)C-iodomethane synthesizer. (11)C-PK11195 was prepared by (11)C-methylation of 1-(2-chlorophenyl)-N-(1-methylpropyl)-3-isoquinoline carboxamide (N-demethyl-PK 11195) as the precursor with (11)C-CH(3)I and purified by semi-preparative reversed phase high performance liquid chromatography (HPLC). The radiochemical purity, chemical purity and stability of the product were evaluated by HPLC, and the toxicity was assessed in normal mice. The factors that affected (11)C-PK11195 synthesis were also studied.
RESULTS(11)C-PK11195 was successfully synthesized using the TracerLab FX(F-N) synthesizer. The synthesis time was about 35 min from the end of (11)C-carbon dioxide production by cyclotron to the end of (11)C-PK11195 synthesis (EOS), with a (11)C-methylation reaction time of 3-4 min. The uncorrected radiochemical yield for (11)C-methylation was (33-/+5)%. Analysis with radio-analytical HPLC showed a radiochemical purity and chemical purity of the product both exceeding 99%, with a specific radioactivity of 30-65 GBq/micromol at EOS (from the end of radionuclide production). The (11)C-PK11195 synthesized was radiochemically stable at room temperature and showed low toxicity in normal mice.
CONCLUSIONThe (11)C-PK11195 injection can be conveniently prepared using an automated synthesizer for clinical use in positron emission tomography.

OBJECTIVE: Vertebral compression fractures (VCFs) are common complications of osteoporosis. The expansion of VCFs with a Sky Bone Expander is a new procedure which improves kyphotic deformities and decreases pain associated with VCFs. The purpose of this study was to investigate the preliminary results for the treatment of painful osteoporotic VCFs with a Sky Bone Expander. MATERIALS AND METHODS: Twenty-six patients with pain-causing VCFs were treated with a Sky Bone Expander. This operation involved the percutaneous insertion of the Sky Bone Expander into a fractured vertebral body transpedicularly. Following the expansion, the Sky Bone Expander was contracted and removed, resulting in a cavity to be filled with bone cement. All fractures were analyzed for improvement in sagittal alignment. Clinical complications, pain relief and ambulation status were evaluated 1 day, 1 week, 1 month, and 3 months after the operation. RESULTS: Twenty-four hours after the operation, all the patients treated experienced some degree of pain relief. In addition, no postoperative neurologic complications were noted. The average operative time was 42.4 +/- 15.5 min per vertebra. Moreover, an average cement volume of 3.5 mL (range, 2.5 +/- 5.0 mL) was injected per vertebra. The average anterior height was 18.4 +/- 5.1 mm preoperatively and 20.5 +/- 5.3 mm postoperatively (p < 0.01). Furthermore, the average midline height was 15.5 +/- 5.2 mm preoperatively and 18.9 +/- 4.0 mm postoperatively (p < 0.01). The Cobb angle improved from 18.5 +/- 8.2 degrees preoperatively to 9.2 +/- 4.0 degrees postoperatively (p < 0.01). The Visual Anabog Scale scores decreased from 7.7 +/- 1.8 points preoperatively to 3.1 +/- 2.0, 2.9 +/- 1.7, 2.6 +/- 1.5 and 2.9 +/- 11.3 after 1 day, 1 week, 1 month and 3 months after the operation, respectively. Cement extrusion was observed in four patients without any neurologic symptoms. CONCLUSION: As a result of this study, we can postulate that the expansion of compressed vetrebra with a Sky Bone Expander is a safe and minimally invasive procedure resulting in the restoration of vertebral body height and the relief of pain associated with VCFs.

OBJECTIVETo investigate the effects of 17-β estradiol (E(2)) and Porphyromonas gingivalis (Pg) W83 on the expression of interleukin (IL)-6 and IL-8 in human periodontal ligament cells (hPDLC).
METHODSPrimary cultures of hPDLC were established and the cells of passage four were treated with 10(-10) mol/L E(2), 10(-7) mol/L E(2) or PgW83 individually or E(2) combined with PgW83. The expression levels of IL-6 and IL-8 protein at 12 h and 24 h were measured with enzyme-linked immunosorbent assay and the levels of mRNA at 24 h were detected with real-time reverse transcriptase polymerase chain reaction.
RESULTSThe expression level of IL-6 reached (2482.88 ± 26.53) ng/L in hPDLC treated with Pg at multiplicity of infection (MOI) of 100 for 24 h, which was significantly higher than that in hPDLC treated with Pg at MOI of 10:1 [(734.09 ± 87.90) ng/L, P = 0.000], the controls [(425.8 ± 77.25) ng/L, P = 0.000] and that in hPDLC treated with Pg at MOI of 100 for 12 h [(1157.50 ± 234.65) ng/L, P = 0.000]. The expression level of IL-8 reached (4965.81 ± 1072.55) ng/L in hPDLC treated with Pg at MOI of 100 for 24 h, which was significantly higher than that in hPDLC treated with Pg at MOI of 10 [(803.51 ± 162.08) ng/L, P = 0.007], the controls [(400.75 ± 2.27) ng/L, P = 0.005] and that in hPDLC treated with Pg at MOI of 100 for 12 h [(1431.12 ± 82.78) ng/L, P = 0.001]. E(2) did not show remarkable effect on the expressions of IL-6 and IL-8. E(2) combined with Pg (MOI = 100:1) significantly promoted the expression levels of IL-6 at 24 h while did not influence those of IL-8. The relative mRNA level of IL-6 in hPDLC treated with 10(-10) mol/L E(2) or 10(-7) mol/L E(2) combined with Pg were 0.49 ± 0.15 (P = 0.021)and 0.53 ± 0.16 (P = 0.036) individually, which were significantly higher than that treated with Pg alone, 0.19 ± 0.06. The protein level of IL-6 in hPDLC treated with 10(-10) mol/L E(2) or 10(-7) mol/L E(2) combined with Pg were (5512.66 ± 1022.07) ng/L (P = 0.012) and (6988.78 ± 2279.13) ng/L (P = 0.000) individually, which were significantly higher than that treated with Pg alone, (3138.46 ± 183.72) ng/L.
CONCLUSIONSPgW83 significantly increased the expression levels of IL-6 and IL-8 in hPDLC in a dose-and time-dependent manner. Without the infection of periodontal pathogens, estrogen may exert no effect on the expression of IL-6 and IL-8 while it may promote the expression of IL-6 in hPDLC when combined with Pg, which may in turn promote the process of periodontal inflammation.

OBJECTIVETo compare the perioperative, functional and oncologic outcomes of patients with prostate cancer receiving laparoscopic radical prostatectomy (LRP) using three-dimensional (3D) versus two-dimensional (2D) imaging systems.
METHODSFrom February, 2014 to January 2016, 72 consecutive patients with clinically localized prostate cancer underwent LRP with 2D or 3D imaging systems performed by a single experienced surgeon. The baseline characteristics, perioperative data, and functional and oncologic outcomes of the patients were collected and analyzed.
RESULTSThirty-six patients underwent 3D LRP and the other 36 patients underwent 2D LRP. Compared with 2D LRP group, 3D LRP group had a significantly shorter operative time (167 vs 218 min, P<0.001), a smaller volume of intraoperative blood loss (86.11 vs 177.78 mL, P<0.001) and a better early urinary continence outcome (88.89% vs 63.89%, P=0.026). No significant differences were found between the two groups in terms of complications, potency outcome or biochemical recurrence-free rate.
CONCLUSIONCompared with 2D LRP, 3D LRP shortens the operative time, reduces intraoperative blood loss and is associated with a better early urinary continence outcome in patients with clinically localized prostate cancer.

OBJECTIVETo evaluate the effectiveness and safety of the meridian three-combined therapy for treatment of ordinary psoriasis.
METHODSA multi-central, randomized and positive drug controlled trial was adopted, and 233 cases were divided into an observation group of 116 cases and a control group of 117 cases. The observation group was treated with thread embedding at points, blood-letting puncture on the back of ear and auricular point pressing (i.e. meridian three-combined therapy). For thread embedding, 3-4 local points such ear points as Fei (CO14), Gan (CO12), Pizhixia (AT4), Shenmen (TF4) , cephalic and symmetric points of severe parts of the limb skin were selected according to the skin lesion position, and the treatment was given once each two weeks. For ear point tapping and pressing, 3-5 points were selected in each session. And the control group was treated with oral administration of Di yin Tablets, 5 tablets each time, twice each day. After treatment of 6 weeks, the clinical therapeutic effects, the score of skin lesion area, the scores for skin lesion severity and safety were compared in the two groups.
RESULTSThe markedly effective rate was 57.8 % in the observation group and 51.3% in the control group with no significant difference between the two groups (P>0.05); after treatment the scores for both the skin lesion area and the skin lesion severity were significantly decreased in the two groups compared with those before treatment (P<0.01), and with a significant difference between the two groups (P>0.05). And the incidence rate of the adverse reaction in the observation group was significantly lower than that in the control group.
CONCLUSIONThe meridian three-combined therapy is effective and safe for treatment of ordinary psoriasis.
