Objective Platelet activating factor(PAF),which has been implicated in the pathophysiology of inflammation in asthma,is degraded and inactivated by PAF acetlhydrolase(PAF AH).To investigate the association of PAF AH activity with genotype in asthmatic children.Methods We studied 57 asthmatic children and 30 normal controls. The plasma PAF AH genotype was detected as representative case with 3 different genotypes (Val/Val,Val/Phe and Phe/Phe) by allele specific polymerase chain reaction(AS PCR).The PAF AH activity in plasam was examined by the changes of substrate assay.Results In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group,and plasma PAF AH activition was absent 15.4 %.In another three groups plasma PAF AH activation were absent 2 %-3 %.There was significant difference of plasma PAF AH activity among 3 groups of genotype(Val/Val,Val/Phe and Phe/Phe).In the similar genotype, there was no significant difference of plasma PAF AH activity between the groups of control and asthma.Conclusions There was imbalace of PAF/PAF AH in asthmatic children. In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group. PAF AH(Val279Phe) gene mutation was related with plasma PAF AH activity.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

OBJECTIVETo observe therapeutic effect of electroacupuncture (EA) on internet addiction disorder (lAD) and to preliminarily probe the mechanism.

METHODSForty-seven cases of TAD were randomly divided into a psychotherapy group and an EA plus psychotherapy group. The psychotherapy group were treated with cognition and behavior therapy, once every 4 days, 10 sessions constituting one course; the EA plus psychotherapy group were treated with EA at Baihui (GV 20), Sishencong (EX-HN 1), Hegu (LI 4), Taichong (LR 3), Neiguan (PC 6), Sanyinjiao (SP 6), etc. once every other day, for 20 sessions, in combination with the same psychotherapy as that in the psychotherapy group. Changes of score of lAD, score of anxiety self-rating scale (SAS), score of Hamilton anxiety scale (HAMA) and serum norepinephrine (NE) content before and after treatment were observed.

RESULTSThe total effective rate was 91.3% in the EA plus psychotherapy group and 59.1% in the psychotherapy group, the former being better than the latter (P<0.05). The scores for IAD, SAS, HAMA, and the se-rum NE content after treatment were significantly decreased in the two groups (both P<0.01). Those in the EA plus psychotherapy group were significantly lower than those in the psychotherapy group (P<0.05).

CONCLUSIONElectroacupuncture combined with psychologic interference can significantly improve anxiety state and the mechanism is possibly related with the decrease of NE in the body.

BACKGROUNDResection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas.

METHODSBetween 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35-84 years old). Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18-84 months).

RESULTSMean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7%) exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19-30).

CONCLUSIONSComputer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill.

OBJECTIVETo study the effects of strychnos alkaloids on the proliferation of adult rat neuroprogenitor cells.

METHODSStrychnos alkaloids free of strychnine and brucine were extracted from Strychnos nux vomica, and the effects of Strychnos alkaloids on the survival of HEK293 and PC12 cells were evaluated using MTT assay. In vitro cultured adult rat neuroprogenitor cells isolated from the hippocampus were treated with different concentrations of Strychnos alkaloids for 2 days, and the cell proliferation was assessed using BrdU incorporation assay.

RESULTSAt the concentration above 0.5 mg/ml, Strychnos alkaloids produced toxic effect against HEK293 cells (P<0.0001), while for PC12 cells, Strychnos alkaloids inhibited the cell survival at the concentration as low as 5 microg/ml (P<0.0001). After 2 days of exposure to 50 microg/ml Strychnos alkaloids, the neuroprogenitor cells showed significantly decreased number of BrdU-positive cells (P<0.01), but the total cell number remained stable when compared with that of the control cells (P>0.05), whereas at the concentration of 100 microg/ml, Strychnos alkaloids produced obvious cytotoxicity against the neuroprogenitor cells.

CONCLUSIONStrychnos alkaloids can significantly inhibit the proliferation of adult rat neuroprogenitor cells, and this effect is probably selective, suggesting the potential of Strychnos alkaloids as a new drug for treatment of neurocytoma.

This study was aimed to evaluate whether mesenchymal stem cells (MSCs) obtained from patients with myelodysplastic syndrome possess immunosuppressive effect. MSCs from bone marrow samples of MDS patients were isolated, cultured and expanded. MSCs were morphologically analyzed and their immunophenotype were determined by flow cytometry. Various amounts of MSCs were added into one-way mixed lymphocyte reaction. MSCs from MDS patients were tested for their ability to suppress in vitro proliferation of autologous and allogeneic peripheral blood lymphocytes (PBLs). The results showed that 3 x 10(3 - 1) x 10(5) MSCs from MDS patients could inhibit autologuous PBLs proliferation to (66.9 +/- 20.1)% - (30.2 +/- 5.9)% of maximal response, as well as inhibit allogeneic PBLs proliferation to (56.6 +/- 14.7)% - (20.5% +/- 9.7)% of maximal response, as compared with inhibitory ability of MSCs from healthy donors, there was no significant difference (P>0.05). It is concluded MSCs from patients with myelodysplastic syndrome also possess immunosuppressive activity.
