Objective To investigate whether perfusion-weighted imaging (PWI) can be used to evaluate blood perfusion of patients with leukoaraiosis (LA), its relationship to clinical features, and the therapy effect of LA. Methods The 44 patients with LA were recruited in the study. All the subjects were examined with both conventional and dynamic susceptibility contrast-enhanced perfusion MR imaging, 13 of them repeated the examinations after the treatment. The shapes and sizes of the biggest lesions in each patient were confirmed by conventional MR imaging, then the values of relative cerebral blood volume (rCBV), relative cerebral blood flow (rCBF) and relative mean transit time (rMTT) in each lesion were calculated respectively. Furtherly, a Pearson's correlation analysis was performed to show whether these values were correlated with mini-mental state examination (MMSE)scores or activities of daily living (ADL) scores. Results The 44 lesions of all the subjects showed significant decreases in rCBV (0. 797 ± 0. 160) and rCBF (0. 779± 0. 164) but increase in rMTT (1. 029±0. 073). There were positive correlations between rCBV and MMSE (r = 0. 524, P =0. 000), between rCBV and ADL (r=0. 621, P=0. 000), between rCBF and MMSE (r=0. 555, P=0. 000), and between rCBF and ADL (r= 0. 690, P= 0. 000), and negative correlations between rMTTand MMSE (r=-0.307, P=0.043), and between rMTT and ADL (r=-0.434, P=0. 003). The blood perfusion was enhanced in 10 out of 13 patients who received the repeated examinations after the treatment, most of whom showed the improvement of clinical symptoms.Conclusions Perfusion MR imaging can assess hemodynamic alterations in LA, which could reflect the clinical symptoms. Moreover, the changes of blood perfusions can be used to evaluate and monitor the therapy effect of LA.

OBJECTIVETo observe therapeutic effect of photoelectric treatment instrument on simple obesity.

METHODSSixty cases of simple obesity were randomly divided into two groups, 30 cases in each group. The treatment group were treated with photoelectric treatment instrument combined with acupuncture, i.e. after acupuncture, the electrodes of XS-998A photoelectric treatment instrument were placed at points of the abdomen, with the laser out-put head on Shenque (CV 8), Shuifen (CV 9) or the parts with much fat, or close to the liver area for the patient of fat liver. The control group were treated with routine acupuncture alone. Changes of main symptoms and signs, and BMI before and after treatment were investigated in the two groups.

RESULTSThe symptoms and signs, and BMI were more significantly improved in the treatment as compared with the control group with a significant difference between the two groups (P < 0.05).

CONCLUSIONAcupuncture combined with laser radiation at the relative area on the abdomen can increase the therapeutic effect on obesity.

OBJECTIVETo investigate the application of three-dimensional CT(3D-CT) in the treatment of oblique facial clefts with mandibular outer cortex, including the surgical design and results assessment.

METHODSFrom Jan. 2003 to Dec. 2013, 22 cases with oblique facial cleft, who underwent mandibular outer cortex onlay bone graft were retrospectively studied. 3D images from CT data were reconstructed before operation for design. Then the mandibular outer cortex onlay bone transplant was performed to reconstruct the bone defect and cleft. 3D CT was performed 5-10 days postoperatively and 6- 12 months postoperatively to assess the facial symmetry.

RESULTSAccording to the results of CT measurement, the average volume of the orbital bone defects on the affected side decreased by(64. 6 ± 14. 4)% 5 to 10 days after operation. The average volume of the maxillary and zygomatic bone defects on the affected side decreased by(71.4 ± 15.7)% after surgery. After 6 to 12 months,the average recovery of the mandibular donor site was (57. 9 ± 13. 9)% of the removed mandibular outer cortex. The average absorption of grafted bones was(24.7 ± 25.6 )%. The average height difference between the centre of pupils on both sides before surgery was(3.76 ± 1.27) mm,which decreased to( 1. 15 ± 1.00) mm 5 to 10 days after surgery(P =0. 000) , and( 1.35 ± 1. 13) mm 6 to 12 months after surgery(P = 0. 003). The relapse may be caused by the absorption of the grafted bones.

CONCLUSIONS3D-CT can be used for preoperative design and postoperative assessment in the treatment of oblique facial cleft with mandibular outer cortex.

Phytantriol (PT), ethanol (ET) and water were used to prepare in situ cubic liquid crystal (ISV2). The pseudo-ternary phase diagram of PT-ET-water was constructed and isotropic solution formulations were chosen for further optimization. The physicochemical properties of isotropic solution formulations were evaluated to optimize the composition of ISV2. In situ hexagonal liquid crystals (ISH2) were prepared based on the composition of ISV2 with the addition of vitamin E acetate (VitEA) and the amount of VitEA was optimized by in vitro release behavior. The phase structures of liquid crystalline gels formed by ISV2 and ISH2 in excess water were confirmed by crossed polarized light microscopy and small angle X-ray scattering, respectively. Rheological properties of ISV2 and ISH2 were studied by a DHR-2 rheometer. In vitro drug release studies were conducted by using a dialysis membrane diffusion method. Pharmacokinetics was investigated by determination of sinomenine hydrochloride (SMH) concentration in synovial membrane after intra-articular injection of SMH-loaded ISH2 in adjuvant-induced arthritis rats. The optimal ISV2 (PT/ET/water, 64 : 16 : 20, w/w/w) loaded with 6 mg x g(-1) of SMH showed a suitable pH, injectable and formed a cubic liquid crystalline gel in situ with minimum water absorption in the shortest time. The optimal ISV2 was able to sustain the drug release for 144 h. The optimal ISH2 system was prepared by addition of 5% VitEA into PT in the optimal ISV2 system. This ISH2 (PT/VitEA/ET/water, 60.8 : 3.2 : 16 : 20, w/w/w/w) was an injectable isotropic solution with suitable pH. The new ISH2 was able to sustain the drug release for more than 240 h. Local pharmacokinetics study indicated that the retention time and AUC(0-∞) of ISH2 group were increased significantly compared with that of SMH solution group and the AUC(0-∞) of ISH2 group was 6.01 times higher than that of SMH solution group. The developed ISH2 was suitable for intra-articular injection that may apply to patients in the treatment of rheumatoid arthritis.
