Objective To investigate the effects of subchronic arsenic exposure on caspase-3 expression in Leydig cells and serum testosterone level in rats. Methods Forty SD rats were divided into four groups based on body mass (160-220 g) by random number table, 10 in each group and treated with As2O3 through drinking water at the doses of 0.0 (distilled water), 2.0, 12.0 and 60.0 mg/L for 14 weeks. Blood sample from heart was collected, serum testosterone was measured by enzyme linked immunosorbent assay (ELISA); the testicular tissue of rats was taken, the expression of caspase-3 was assayed by immunohistochemical staining, and its average gray value was analyzed with image analysis software (Biomias). Results There were statistically significant differences of the serum testosterone levels between groups (F= 37.99, all P< 0.05). Compared with the control group [(3.082 3 ± 0.653 0) ng/L], serum testosterone levels in middle-dose and high-dose groups [(1.694 6 ± 0.255 4), (1.350 5 ± 0.281 9)ng/L] were significantly lower (all P< 0.05). The numbers of positive cells of caspase-3 were 8.10 ± 1.91, 9.80 ± 2.15,10.00 ± 1.83 and 10.90 ± 2.38 in each vision in the 4 groups, there were statistically significant differences between groups (F=3.17, all P<0.05), compared with the control group , the middle-dose and high-dose groups were significantly higher (all P<0.05);the average gray values of caspase-3 were 135.10 ± 6.89, 130.00 ± 3.30, 117.10 ± 4.28, and 113.10 ± 5.38, there were statistically significant differences between groups (F = 41.09, P < 0.05), compared with the control group, the middle-and high-dose groups were decreased (all P<0.05). Conclusions One possible mechanism of As2O3 on male germ cell toxicity may be through up-regulation of the expression of caspase-3 in Leydig cells of SD rats and initiating the pathway of the apoptosis signal, which can lead to increased apoptosis of Leydig cells, decreased concentrations of testosterone, and damaged reproductive function in rats.

Objective: To observe the clinical efficacy of combining auricular point sticking and a healthy diet to treat simple obesity in children aged 6-9 years old.Methods: A total of 190 eligible obese kids were divided into an observation group and a control group using the random number table method, with 95 cases in each group. The observation group was intervened by auricular point sticking plus guide on a healthy diet, while the control group was only provided with the guide on a healthy diet. The therapeutic efficacy was observed after intervention for three consecutive months, as well as the changes in body mass (BM), body mass index (BMI), waist circumference (WC), hip circumference (HC), and subcutaneous fat thickness. Results: After the 3-month intervention, the total effective rate was 91.6％ in the observation group, versus 74.7％ in the control group, and the between-group difference was statistically significant (P<0.01); in both groups, the BM, BMI, WC, HC, and subcutaneous fat thickness all decreased significantly (P<0.05), and were lower in the observation group than in the control group, showing statistical significance (P<0.05). Conclusion: Auricular point sticking plus a healthy diet is safe and effective in treating simple obesity in children, producing more significant efficacy than healthy diet intervention alone.

OBJECTIVETo study the combination of Mandibular distraction and orthognathic techniques for the reconstruction of adult hemifacial microsomia.

METHODSThe three-dimensional CT reconstruction data was used with Mimics for preoperation design. The osteotomy location, distraction vector, distraction distance were decided before operation with a surgical guider. At the first stage, internal distractor was implanted after ostetomy through an extra-oral approach. The distraction begun 5-7 days after operation with a frequency of 1 mm/day. After distraction, the distractor was maintained for 3-6 months. At the second stage, the distractor was removed. Le Fort I osteotomy was performed in order to correct the cross-bite and improve the facial contour. Usually, bone graft was inserted into the gap after Le Fort I osteotomy. The genioplasty was also performed if necessary.

RESULTS9 cases of adult hemifacial microsomia with severe mandibular deviation were treated. The facial asymmetry were improved greatly. 1 patient suffered an wound infection in the maxillary region after Le Fort I osteotomy and healed uneventfully with wound irrigation.

CONCLUSIONSMandibular distraction combined with orthognathic surgery is an effective procedure for adult hemifacial microsomia with complicated mandibular hypoplasia.

Objective To investigate the safty and accuracy ot estimating the living donor's graft volume with IQQA liver imaging evaluation system.Methods Between June 2007 and July 2010,123living liver donors were enrolled to undergo 16-slice CT scanning,then graft volume was estimated by both IQQA and manu-traced multi-slice spiral computed tomography (MSCT) approach.The graft volume and time consuming between IQQA and manu-traced MSCT were compared. Pearson Correlation test was uesd to verify the correlation between the estimated graft volume estimated each method and actual graft weight detected in operation.Linear correlation analysis was done.Results The mean graft volume by IQQA and manu-traced MSCT was (856.76 ± 162.18) and (870.64 ±172.54) cm3 respectively preoperation.Paired t-test showed there was no statistically significant difference between IQQA and MSCT methods (P＞0.05).It took mean ( 16.9 ± 1.4) min to calculatethe graft volume by IQQA and (39.3 ± 2.1 ) min by manu-traced MSCT,respectively (P＜0.05).The real graft volume was (632.59 ± 13 1.73) cm3.Pearson correlation test showed the graft volume calculated by either IQQA or MSCT method had a significantly positive correlation with the real graft weight (MSCT r =0.921,IQQA r =0.896,P＜0.01 ).Graft weight could be expressed in the equation:Actual graft weight =- 150.303 + 1.025 × IQQA value or =- 94.397 + 0.955 × MSCT value.Conclusion IQQA system has same accuracy with MSCT method in predicting the graft volume but consuming less time.IQQA system promotes the recognition of clinician on liver three dimensional anatomic structure.

OBJECTIVETo determine the effects of Jiji decoction (Traditional Chinese Medicine) on the cognitive function and oxidative stress in mice with vascular dementia (VD) induced by cerebral ischemia/reperfusion.

METHODSThirty-two mice were randomly divided into nonnal group (n = 8), sham group (operation, but no cerebral ischemia/reperfusi6n, n = 8), model group (vascular dementia model induced by cerebral ischemia/reperfusion, n = 8), and Jiji decoction-treated group (vascular dementia model plus treatment with Jiji decoction, n = 8). Fourteen days of treatment after operation, the cognitive behavior was measured in step-through test, spatial probe test and platform test. Afterwards, to assess the levels of oxidative stress, the activity of superoxide dismutase(SOD) and content of malonaldehyde (MDA) in brain of these mice were measured.

RESULTSData from step-through test indicated that the escaping latency of Jiji decoction-treated group was prolonged and the error counts were decreased significantly ( P <0.01) compared with those of model group. Data from spatial probe test indicated that the time of entering darkroom, the time of climbing height and the time of entering bright room in Jiji decoction-treated group were shortened and the counts of climbing height were increased (P < 0.05-0.01) significantly compared with those of model group. Data from platform test showed that the escaping latency of Jiji decoction-treated group was prolonged significantly (P < 0.01) compared with that of model group. Compared with normal and sham group, the activity of SOD was decreased and the content of MDA was increased in model group significantly (P < 0.01). Compared with those of model group, the levels of SOD and MDA in Jiji decoction-treated group were improved significantly (P < 0.01).

CONCLUSIONJiji decoction could improve cognitive function of VD mice. Its mechanism might be related with the inhibition of oxidative stiess in the brain.
